Background

With the development of economy and the improvement of the living standard of people, refrigeration equipment such as air conditioners, refrigerators or freezers and the like become common household appliances for thousands of households. The vacuumizing process in the production process of the refrigeration equipment is an important process in the production process of the refrigeration equipment, and poor vacuumizing can cause the problems of shortened service life of a compressor of the refrigeration equipment, loud sound during working, increased running power consumption and the like.

In the related art, the vacuum pumping result of the refrigeration equipment is usually determined based on the positive vacuum pump indication index, for example, when the indication value of the vacuum pumping equipment is smaller than the set threshold value, the red light of the vacuum pumping equipment indicator light is changed into the green light, which indicates that the vacuum pumping result of the refrigeration equipment is qualified. However, in the above scheme, when a pipeline of the refrigeration equipment slightly leaks, the vacuumizing result of the refrigeration equipment is still judged to be qualified, which may cause refrigerant leakage in the use process of the refrigeration equipment, and further cause a problem that normal refrigeration cannot be performed. Therefore, how to provide an accurate vacuum result determination scheme has become one of the technical problems to be solved at present.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

FIG. 1 is a flow chart illustrating a method of determining a vacuum result according to an exemplary embodiment; the method of the embodiment can be applied to a vacuum result determination device (e.g., a data processor, a smart phone, a tablet computer, a notebook computer, etc. integrated in the vacuum device).

As shown in fig. 1, the method comprises the following steps S101-S103:

in step S101, in response to detecting that the vacuum-pumping device completes the vacuum-pumping process of the target refrigeration device, a first indication value of the vacuum-pumping device is obtained.

In this embodiment, in the process of producing or maintaining the target refrigeration equipment, when the target refrigeration equipment needs to be subjected to the vacuumizing process, the vacuumizing equipment may be connected with the target refrigeration equipment, and the target refrigeration equipment may be subjected to the vacuumizing process. After the vacuum-pumping process is completed, in order to determine the vacuum-pumping result of the target refrigeration equipment (i.e. to check whether the vacuum degree of the target refrigeration equipment is qualified), a current indication value of the vacuum-pumping equipment may be obtained (for convenience of distinguishing, this value is named as a first indication value). It is worth mentioning that when the first indication value is obtained, the target cooling device is connected to the vacuum extractor.

For example, the target refrigeration device may include a refrigerator, an air conditioner, a freezer, an ice bar, and the like, and the vacuum pumping device may include a vacuum pumping pump, which is not limited in this embodiment.

In step S102, a difference between the first and second indicated values is determined.

In this embodiment, after the first indication value of the vacuum pumping device is obtained in response to detection that the vacuum pumping device completes a vacuum pumping process on the target refrigeration device, a difference between the first indication value and the second indication value may be determined. The second vacuumizing equipment indication value is an indication value of the vacuumizing equipment under the target condition, and the target condition comprises the condition that the target refrigerating equipment is not vacuumized and is not connected with the vacuumizing equipment.

For example, before the target device is subjected to the vacuum-pumping process, an indication value of the vacuum-pumping device may be obtained (for convenience of distinguishing, the indication value is named as a second indication value), and then a difference between the first indication value and the second indication value may be calculated.

In step S103, a vacuum pumping result of the target refrigeration equipment is determined based on the first indication value and the difference value.

In this embodiment, after determining the difference between the first indication value and the second indication value, the evacuation result of the target refrigeration equipment may be determined based on the first indication value and the difference.

In an embodiment, after determining a difference between the first indication value and the second indication value, the difference may be determined based on a preset difference threshold, and the first indication value may be determined based on a preset indication value threshold, so that the first indication value may be determined based on a determination result of the two values. For example, when the difference is judged to be excessive based on a preset difference threshold value, it may be judged that the pipe of the target refrigeration equipment is slightly leaked, and when the first indication value is judged to be excessive based on a preset indication value threshold value, it may be judged that the vacuum degree of the target equipment is not qualified.

On the contrary, only when the difference is judged not to exceed the set difference threshold value and the first indication numerical value does not exceed the set indication numerical value, the target refrigeration equipment can be judged not to leak and the vacuum degree is qualified. In this case, it can be determined that the evacuation result of the target refrigeration apparatus is acceptable. Therefore, the problem that the vacuumizing result of the refrigeration equipment is judged to be qualified under the condition that the pipeline of the refrigeration equipment slightly leaks in the related technology can be solved.

In another embodiment, the manner of determining the vacuum pumping result of the target refrigeration equipment based on the first indication value and the difference value can also be referred to the following embodiment shown in fig. 2, and will not be described in detail herein.

As can be seen from the above description, in this embodiment, by responding to the detection that the vacuum-pumping device completes the vacuum-pumping process on the target refrigeration device, obtaining a first indication value of the vacuum-pumping device, then determining a difference value between the first indication value and a second indication value, and further determining the vacuum-pumping result of the target refrigeration device based on the first indication value and the difference value, since the first indication value of the vacuum-pumping device is obtained when the vacuum-pumping process on the target refrigeration device is completed and the target refrigeration device and the vacuum-pumping device are in a connected state, and the difference value between the first indication value and the second indication value when the vacuum-pumping process on the target refrigeration device is not performed is determined, further determining the vacuum-pumping result of the target refrigeration device based on the first indication value and the difference value can be achieved subsequently, compared with the scheme that the vacuumizing result of the refrigeration equipment is judged only based on the indication value of the vacuumizing equipment in the related art, whether the pipeline of the target refrigeration equipment leaks slightly or not can be accurately detected based on the difference value, and the accuracy of judging the vacuumizing result of the target refrigeration equipment can be improved.

FIG. 2 is a flow chart showing how the evacuation result of the target refrigeration appliance is determined based on the first indicator value and the difference value in accordance with an exemplary embodiment. The present embodiment is exemplified by how to determine the evacuation result of the target refrigeration equipment based on the first indication value and the difference value on the basis of the above-described embodiments. As shown in fig. 2, the step S103 of determining the vacuum pumping result of the target refrigeration equipment based on the first indication value and the difference value includes the following steps S201 to S203:

in step S201, the first indication value is compared with a first preset threshold value, and the difference value is compared with a predetermined difference threshold value.

In this embodiment, after acquiring a first indication value of the vacuum pumping device and determining a difference between the first indication value and a second indication value, the first indication value may be compared with a first preset threshold, and the difference may be compared with a predetermined difference threshold.

The size of the first preset threshold may be set based on actual needs, for example, set to 15Pa, and the like, which is not limited in this embodiment.

The predetermined difference threshold may be determined based on sampling statistics of the sample refrigeration equipment and the vacuum-pumping equipment on the current production line, and the specific determination manner may be referred to the embodiment shown in fig. 3, which will not be described in detail herein.

In step S202, in response to determining that the first indication value is smaller than the first preset threshold and the difference value is smaller than the difference threshold, determining the vacuum pumping result of the target refrigeration equipment as a first result. And the first result is used for representing that the vacuumizing result of the target refrigeration equipment is qualified.

In this embodiment, after comparing the first indication value with a first preset threshold and comparing the difference with a predetermined difference threshold, if it is detected that the first indication value is smaller than the first preset threshold and the difference is smaller than the difference threshold, the vacuum pumping result of the target refrigeration equipment may be determined as the first result, that is, the vacuum pumping result of the target refrigeration equipment is determined to be qualified.

In one embodiment, an indicator light of the vacuum-pumping device can be triggered to turn to green light to prompt the user that the vacuum-pumping result of the target refrigeration device is qualified.

In step S203, in response to determining that the first indication value is greater than or equal to the first preset threshold value, or the difference value is greater than or equal to the difference threshold value, determining the vacuum pumping result of the target refrigeration equipment as a second result. And the second result is used for representing that the vacuumizing result of the target refrigeration equipment is unqualified.

In this embodiment, after comparing the first indication value with a first preset threshold and comparing the difference with a predetermined difference threshold, if it is detected that the first indication value is greater than or equal to the first preset threshold, or the difference is greater than or equal to the difference threshold, the vacuum pumping result of the target refrigeration equipment may be determined as a second result, that is, it is determined that the vacuum pumping result of the target refrigeration equipment is not qualified.

In one embodiment, the indicator light of the vacuum-pumping device can be triggered to change to a red light to indicate that the vacuum-pumping result of the target refrigeration device is not qualified.

As can be seen from the above description, in this embodiment, by comparing the first indication value with a first preset threshold value and comparing the difference value with a predetermined difference threshold value, when it is determined that the first indication value is smaller than the first preset threshold value and the difference value is smaller than the difference threshold value, the vacuum pumping result of the target refrigeration equipment is determined to be qualified, and when it is determined that the first indication value is greater than or equal to the first preset threshold value or the difference value is greater than or equal to the difference threshold value, the vacuum pumping result of the target refrigeration equipment is determined to be unqualified, so that the vacuum pumping result of the target refrigeration equipment can be accurately determined based on the first indication value and the difference value.

FIG. 3 is a flow chart illustrating how the difference threshold is determined in accordance with an exemplary embodiment; the present embodiment takes how to determine the difference threshold as an example to illustrate on the basis of the above embodiments. As shown in fig. 3, the present embodiment may further include, on the basis of the above-mentioned embodiment, determining the difference threshold based on the following steps S301 to S304:

in step S301, for a first number of non-leaking refrigeration apparatuses, a maximum difference of the indicated values of the evacuation apparatuses after the evacuation process and before the evacuation process is determined as a first maximum difference.

The non-leakage refrigeration equipment can comprise refrigeration equipment with a non-leakage pipeline.

In one embodiment, a first target number of sample refrigeration devices may be tested based on a predetermined testing method to obtain the first number of no-leak refrigeration devices. It is understood that the first target number is greater than or equal to the first number.

It should be noted that the preset inspection method may be set based on actual needs, such as a helium inspection method in the related art (i.e., a method of introducing helium gas into the refrigeration equipment to determine whether there is a leakage in the pipeline of the refrigeration equipment through a helium gas leakage amount), and this embodiment does not limit this.

In step S302, a minimum difference in the indicated value of the evacuation device after the evacuation process and before the evacuation process is obtained for a second number of slightly leaking refrigeration devices.

The slight leakage refrigeration equipment comprises refrigeration equipment, wherein although a pipeline leaks, the leakage amount in a preset time period is smaller than a set threshold value.

It should be noted that the leakage amount in the preset time period may be set based on actual needs, for example, the leakage amount is set to be less than 0.3g per year, and the present embodiment does not limit this.

In one embodiment, a second target number of sample refrigeration devices may also be tested for the second number of light leak refrigeration devices based on a predetermined test method such as the helium test method described above. It is understood that the second target number is greater than or equal to the second number.

In step S303, after the second number of slightly leaking refrigeration devices are repaired to obtain the second number of non-leaking refrigeration devices, for the second number of non-leaking refrigeration devices, a maximum difference between indication values of the vacuuming device after the vacuuming process and before the vacuuming process is determined as a second maximum difference.

In an embodiment, after the second number of slight-leakage refrigeration devices are repaired, the repaired refrigeration devices may be inspected based on the preset inspection method to ensure that the second number of slight-leakage refrigeration devices are maintained as leakage-free devices, so that the second number of leakage-free refrigeration devices can be obtained.

In step S304, in response to determining that the difference between the first maximum difference and the second maximum difference is less than a set difference threshold and the first maximum difference is less than the minimum difference, the first maximum difference is determined to be the difference threshold.

For example, when the maximum difference between the indication values of the vacuuming equipment after the vacuuming process and before the vacuuming process is determined as the first maximum difference a for the first number of non-leakage refrigerating equipments, and the minimum difference B between the indication values of the vacuuming equipment after the vacuuming process and before the vacuuming process is obtained for the second number of light-leakage refrigerating equipments, the second number of light-leakage refrigerating equipments may be repaired to obtain the second number of non-leakage refrigerating equipments, and then the maximum difference between the indication values of the vacuuming equipment after the vacuuming process and before the vacuuming process may be obtained for the second number of non-leakage refrigerating equipments to be determined as the second maximum difference C, on the basis of which, if the difference between the first maximum difference and the second maximum difference is detected to be smaller than the set difference threshold (wherein, the set difference threshold may be set to a small value based on actual needs, i.e., such that A ≈ C) and the first maximum difference is less than the minimum difference (i.e., A ≈ C < B), the first maximum difference A may be determined as the difference threshold.

In an embodiment, the method of this embodiment may further include acquiring the number of the vacuum-pumping devices on the current production line, and then determining the first number and/or the second number based on the number of the vacuum-pumping devices and a preset ratio.

For example, if the number of vacuum-pumping devices on the current production line is 60, the first number of leak-free refrigeration devices can be determined according to a ratio greater than 1/3, i.e., the number of leak-free refrigeration devices is greater than 20. Similarly, a second number of light leak refrigerators may be determined on a scale greater than 1/3, i.e., the number of light leak refrigerators may be greater than 20. It is understood that in practical applications, the number of the non-leakage refrigeration devices can be greater than or equal to or less than the number of the slight-leakage refrigeration devices based on actual needs, and the embodiment does not limit the number.

As can be seen from the above description, in this embodiment, by determining, for a first number of non-leakage refrigeration apparatuses, the maximum difference between indication values of the evacuation apparatuses after the evacuation process and before the evacuation process as a first maximum difference, and for a second number of slight-leakage refrigeration apparatuses, obtaining the minimum difference between indication values of the evacuation apparatuses after the evacuation process and before the evacuation process, and then after performing maintenance on the second number of slight-leakage refrigeration apparatuses to obtain the second number of non-leakage refrigeration apparatuses, for the second number of non-leakage refrigeration apparatuses, determining, as a second maximum difference, the maximum difference between indication values of the evacuation apparatus after the evacuation process and before the evacuation process, and then in response to determining that the difference between the first maximum difference and the second maximum difference is smaller than a set difference threshold, and the first maximum difference is smaller than the minimum difference, the first maximum difference is determined as the difference threshold, so that the difference threshold can be accurately determined, the vacuumizing result of the target refrigeration equipment can be determined subsequently based on the difference threshold and the comparison result of the difference between the first indication value and the second indication value, and the accuracy of the vacuumizing result determination of the target refrigeration equipment can be improved.

FIG. 4 is a block diagram illustrating an evacuation result determination device according to an exemplary embodiment; the device of the embodiment can be applied to a vacuumizing result judging device (such as a data processor, a smart phone, a tablet computer, a notebook computer and the like integrated in the vacuumizing device).

and the vacuumizing result judging module 130 is configured to judge a vacuumizing result of the target refrigeration equipment based on the first indication value and the difference value.

As can be seen from the above description, in this embodiment, by responding to the detection that the vacuum-pumping device completes the vacuum-pumping process on the target refrigeration device, obtaining a first indication value of the vacuum-pumping device, then determining a difference value between the first indication value and a second indication value, and further determining the vacuum-pumping result of the target refrigeration device based on the first indication value and the difference value, since the first indication value of the vacuum-pumping device is obtained when the vacuum-pumping process on the target refrigeration device is completed and the target refrigeration device and the vacuum-pumping device are in a connected state, and the difference value between the first indication value and the second indication value when the vacuum-pumping process on the target refrigeration device is not performed is determined, further determining the vacuum-pumping result of the target refrigeration device based on the first indication value and the difference value can be achieved subsequently, compared with the scheme that the vacuumizing result of the refrigeration equipment is judged only based on the indication value of the vacuumizing equipment in the related art, whether the pipeline of the target refrigeration equipment leaks slightly or not can be accurately detected based on the difference value, and the accuracy of judging the vacuumizing result of the target refrigeration equipment can be improved.
