In order to make the objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.

Fig. 1 is a schematic structural view of a refrigeration apparatus in an embodiment of the present invention, the schematic structural view being a perspective view in a housing groove portion.

As shown in fig. 1, the refrigerating apparatus 10 includes a cabinet 100 and a receiving groove 300 for receiving a power module (not shown in fig. 1).

In some specific examples, the refrigeration device 10 may be an appliance, such as a refrigerator or freezer, adapted to store items and keep them cool.

Specifically, the refrigeration appliance 10 may include a cabinet 100, and the cabinet 100 may include a cabinet body and a door body. The box body is used for forming a cavity which is suitable for storing articles and is provided with a taking and placing opening; the door body is connected with the box body and is suitable for moving relative to the box body to open or close the taking and placing opening of the chamber.

Fig. 2 is a schematic view of the structure of a wall in an embodiment of the invention.

Referring to fig. 1 and 2, the wall 200 includes at least one exposed end 210. The receiving groove 300 is disposed in the wall 200 and has an inlet 310 formed at the end 210. The power module 20 may be disposed in the receiving groove 300 through the inlet 310.

In some specific examples, the wall 200 may be formed by a box body. It should be noted that the wall 200 formed by the box body should include at least one exposed end 210 to facilitate the placement of the receiving groove 300 and its entrance 310.

In other preferred embodiments, the wall 200 may also be formed by a door. The door body typically includes at least one exposed end 210. For example, the door body mounted to one side of the cabinet body may include an upper end portion, a lower end portion, and side end portions.

Referring to fig. 1, the refrigeration appliance 10 includes two half-opened door bodies, with a wall 200 formed by one of the door bodies and having exposed upper, lower and side ends.

In other specific examples, the receiving groove 300 may also be located at a side or lower portion of the wall 200 and have an inlet 310 formed at a side or lower end portion.

However, in the example shown in fig. 1, the inlet 310 of the receiving groove 300 is disposed at the side end of the wall 200, which may affect the aesthetic appearance of the door body; the entrance of the receiving groove 300 is formed at the lower end of the wall 200, which makes the use of the receiving groove 300 inconvenient. Thus, it is preferable that the receiving groove 300 is provided at an upper portion of the wall 200 and has an inlet 310 formed at an upper end portion.

Fig. 3 is a schematic structural view of the power consuming module according to the embodiment of the present invention, which is illustrated in a perspective view at the embedded portion.

As shown in fig. 3, the power module 20 may include an insertion portion 21 and a top cover 22 positioned above the insertion portion 21. The power module 20 is fitted into the housing groove 300 through the fitting portion 21, and the inlet 310 is closed by the top cover 22. The insertion portion 21, the top cover 22 and the receiving groove 300 are preferably made of non-metal materials. The power utilization module 20 further includes a power utilization element 23, and the power utilization element 23 is disposed in the insertion portion 21 and is received in the receiving space formed by the receiving groove 300 along with the insertion portion 21.

In some specific examples, the receiving groove 300 has an inner contour matching an outer contour of the embedding part 21 so that the embedding part 21 can be tightly embedded in the receiving groove 300.

In other embodiments, the insert 21 may be integrally formed with the cover 22, and both may be made of a non-metal material, such as a plastic material.

The insertion portion 21 further has a receiving cavity therein for receiving the electric element 23, so as to better fix and support the electric element 23 in the receiving cavity 300.

In some specific examples, the power consuming elements 23 may include one or more of communication elements, display elements, or sensing elements, among others.

Fig. 4 is a partial schematic view of a wall in an embodiment of the invention.

As shown in fig. 4, the end 210 is provided with a first recess 211 adapted to receive the top cover 22.

In some specific examples, the first recess 211 is sized and configured to cooperate with the top cover 22 to better receive the top cover 22 and to provide a top surface of the top cover 22 that is flush with a top surface of the end 210.

In other embodiments, the cover 22 may be fixedly attached to the wall 200.

With continued reference to fig. 3 and 4, the top cover 22 may be provided with a screw 24, the wall 200 and the end portion 210 thereof may be provided with a threaded hole 212 in the first recess 211 for engagement with the screw 24, and the top cover 22 may be fixedly attached to the end portion 210 of the wall 200 by screwing the screw 24 to the threaded hole 212.

With continued reference to fig. 4, the first recess 211 may also be provided with a second recess 213 adapted to receive a depression of the screw 24, with the top end of the threaded hole 212 being located within the second recess 213. In this manner, the screw 24 is better secured in the threaded hole 212 and the top surface of the screw 24 is flush with the top surface of the end 210.

With continued reference to fig. 4, end 210 is further provided with channels 220 at its portion located at the periphery of inlet 310. The guiding groove 220 can guide the liquid around the inlet 310 to a position far away from the inlet 310, so as to prevent the power module 20 disposed in the accommodating groove 300 from being eroded by the liquid.

Fig. 5 is a partial schematic view of an end portion in an embodiment of the invention.

Referring to fig. 4 and 5, the guide groove 220 includes a guide section 221 and a drainage section 222. The flow guide section 221 is disposed around the periphery of the inlet 310, and the liquid discharge section 222 is in communication with the flow guide section 221 and extends beyond the end face 214 of the end portion 210.

FIG. 6 is a partial side cross-sectional view of a wall in an embodiment of the invention.

In conjunction with fig. 5 and 6, the guide groove 220 has an inner bottom wall continuously lowered in the gravity direction G in a direction from the guide section 221 toward the liquid discharge section 222. The inner bottom wall is formed on the end surface of the inner bottom of the guiding gutter 220, and the liquid flowing into the guiding gutter 220 can flow in the guiding gutter 220 along the inner bottom wall. In this way, the liquid around the inlet 310 can flow along the flow guiding section 221 to the liquid discharging section 222 and further out of the end surface 214 of the end portion 210 under the action of its own weight.

In the technical solution provided by the embodiment of the present invention, the gravity direction G is a vertical downward direction.

Referring to fig. 6, a predetermined angle may be formed between S1 and S2 by marking a plane of the end surface 214 of the end portion 210 as S1 and a plane of the inner bottom wall of the guide groove 220 as S2.

In some specific examples, the plane S1 in which the end face 214 of the end portion 210 lies may be parallel to a horizontal plane. In this manner, a predetermined angle is formed between the plane S2 of the inner bottom wall and the horizontal plane. The included angle may make the inner bottom wall of the guiding groove 220 have a slope, so as to guide the liquid around the inlet 310 to a position far away from the inlet 310 through the guiding groove 220, thereby preventing the power module 20 from being eroded by the liquid.

With continued reference to fig. 4 and 5, the flow guide section 221 is located within the first recess 221 and may be covered under the top cover 22. In this way, the liquid in the first recess 221 can flow along the flow guiding section 221 to the liquid discharging section 222 and out of the end surface 214 of the end portion 210 under the action of its own weight.

Fig. 7 is a schematic flow guide diagram of a flow guide groove in an embodiment of the invention.

Referring to fig. 4, 5, and 7, the second recess 213 may communicate with the flow guide section 221. The guide channel 220 may further include a second recess 213 communicating with the guide section 221. The second recess 213 may guide the liquid in the first recess 211 to the liquid discharge section 222 through the flow guiding section 221, or directly to the liquid discharge section 222.

In the example shown in fig. 4, 5, and 7, two second recesses 213 are provided in the first recess 211. The two second recesses 213 are respectively located at both sides of the first recess 211. Wherein, a second recess 213 is connected to the side of the flow guiding section 221 away from the liquid discharging section 222; the other second recess 213 is respectively connected to the side of the flow guiding section 221 close to the liquid discharging section 222 and the liquid discharging section 222, that is, the flow guiding section 221 and the liquid discharging section 222 can be connected through the second recess 213.

In order to smoothly discharge the liquid out of the end surface 214 of the end portion 210, the guide groove 220 has an inner bottom wall continuously decreasing in the direction of gravity along a direction sequentially pointing to the second recess 213 communicating with the side of the guide section 221 away from the liquid discharge section 222, the guide section 221, the second recess 213 communicating with the side of the guide section 221 close to the liquid discharge section 222, and the liquid discharge section 222.

Also, a predetermined angle is formed between the inner bottom wall and the horizontal plane, so that the inner bottom wall has a slope to guide the liquid around the inlet 310 to a position far from the inlet 310 through the guide groove 220, thereby preventing the power module 20 from being corroded by the liquid.

With continued reference to fig. 4, the wall 200 is also provided with a liquid collection portion 230 at a location proximate the end 210 thereof. The liquid collecting portion 230 is located below the end portion 210 and communicates with the liquid discharging section 222, and is used for collecting the liquid guided out through the guiding groove 220.

Since the liquid around the inlet 310 of the receiving groove 300 is small, the liquid collected at the liquid collecting part 230 by the guiding groove 220 can be naturally evaporated to be dry.

Fig. 8 is an exploded view of a wall in an embodiment of the invention.

In the example shown in fig. 8, the wall 200 is formed by a door body of the refrigeration appliance 10.

Fig. 8 illustrates four directions, i.e., up, down, front, and rear, which are determined based on the viewing angle from which the door body faces the user in the normal use state. The front represents the direction of the door body close to one side of a user, the rear represents the direction of the door body far away from one side of the user, the upper represents the direction of the top of the door body, and the lower represents the direction of the bottom of the door body. It should be understood that from other viewing angles of the door body, there may be up, down, front, and back directions corresponding to the respective viewing angles; the up, down, front and rear directions illustrated in fig. 8 are only for convenience of describing technical aspects of the embodiments of the present invention and do not constitute a limiting explanation of the aspects.

As shown in fig. 8, the wall 200 formed by the door body may further include an insulation layer (not shown in fig. 8), a metal plate 240, and a door inner container 250.

The insulation layer is located inside the end portion 210 and defines a receiving space of the receiving groove 300 together with the end portion 210. At least a portion of the receiving groove 300 is located in the adiabatic layer, and the inner sidewall of the end portion 210 and the adiabatic layer serve to form a partial boundary of the receiving space.

In the technical solution provided by the embodiment of the present invention, the inner side of the end portion 210 is a side of the end portion 210 facing the interior of the door body.

In some specific examples, the receiving groove 300 may extend in a plane perpendicular to the thickness direction of the wall 200. Further, the receiving groove 300 may also extend in a length direction of the wall 200. Thus, the thickness of the heat insulation layer occupied by the accommodating groove 300 can be reduced, and the risk of condensation of the power consumption element in the power consumption module 20 is reduced.

In the example shown in fig. 8, the thickness direction of the wall 200 is the front-rear direction of the wall 200, and the longitudinal direction of the wall 200 is the vertical direction of the wall 200.

The metal plate 240 is located inside the end 210, in front of the insulation layer. In one or more preferred embodiments, the metal plate 240 is further provided with a notch 241 at a portion thereof facing the electric element 23. In this way, no metal material or little metal material is provided around the power consumption element 23, so that the wireless signal of the power consumption module 20 can be improved.

The wall 200 may also include a front panel 260 disposed inside the end 210 and attached to the front of the metal plate 240. In some specific examples, the front panel 260 may also be used to form a partial boundary of the receiving space.

Door liner 250 is positioned inside end 210, behind the insulation. In some specific examples, the door inner bladder 250 may also be used to form a partial boundary of the receiving space.

Wall 200 may also include at least one edge card. The side cards may include at least one of a top card 271, a side card 272, and a bottom card 273. End 210 may be formed by an edge card with the insulating layer, metal plate 240, both located on the inside of the edge card.

Referring to fig. 8, the wall 200 includes an upper card 271, a side card 272, and a lower card 273, which are all made of a non-metal material. The upper end portion for disposing the receiving groove 300 is formed by the upper clip 271.

In some specific examples, the plane of the end surface of the upper clip 271 can be parallel to the horizontal plane. However, considering that the thickness of the upper clip 271 is limited, the angle between the plane of the end surface of the upper clip 271 and the plane of the inner bottom wall of the guiding groove 220 may be limited to be greater than or equal to 1 ° to less than or equal to 3 °, so that the inner bottom wall of the guiding groove 220 has a slope to guide the liquid around the inlet 310 to a position far away from the inlet 310 through the guiding groove 220.

In the technical solution provided by the embodiment of the present invention, the power consumption module 20 may include a power consumption element 23 having a wireless communication function. In some specific examples, the power utilization element 23 may be a Printed Circuit Board (PCB) integrated with a wireless communication antenna.

In order to increase the wireless signal of the electric element 23, it is possible to consider both a spatial range closer to the electric element 23 and a spatial range farther from the electric element 23. For a spatial range closer to the electric element 23, the electric element 23 should be used within the range from any object. For a spatial range that is far from the electric element 23, the electric element 23 should be used within the range without interference from any metal object.

In order to solve the above problems, new designs may be made from both the power module 20 and the wall 200, respectively.

Figure 9 is another partial side cross-sectional view of a wall in an embodiment of the invention.

As shown in fig. 9, the wall 200 may be formed by a door body of the refrigeration apparatus 10, and includes a front panel 260, a metal plate 240, a heat insulating layer 270, and an inner container 250, which are sequentially disposed.

The accommodating groove 300 is disposed in the heat insulation layer 270, and the accommodating groove 300 is made of a non-metal material. The housing groove 300 is provided with the power module 20. The power consuming module 20 includes an insertion portion 21. The insert 20 has a receiving cavity 25 adapted to receive the electrical element 23.

In some specific examples, the embedded portion 21 of the power consuming module 20 is made of a non-metal material, and the sidewall of the accommodating cavity 25 is not in contact with the power consuming element 23 and keeps a certain distance.

The specific distance may be generally in millimeter level, and is related to the performance and parameters of the wireless communication antenna in the power consumption element 23, and the specific value may be set according to the specific performance and parameters of the wireless communication antenna in the power consumption element 23.

In this way, by providing a specific distance between the electric element 23 and the side wall of the accommodating cavity 25, the wireless signal of the electric element 23 is prevented from being affected by an object (e.g., the non-metallic embedded part 21) in a close spatial range, so as to improve the wireless signal strength of the electric element 23.

Further, it is necessary to ensure that the wireless signal of the electric element 23 is not interfered by a metal object in a spatial range far from the electric element.

To solve this problem, the refrigeration device 10 may also be made to include no metal within a specific ellipsoidal spatial range a centered on the powered element 23 to reduce or eliminate interference of the metal with the wireless signal of the powered element 23.

The specific ellipsoid spatial range is related to the performance and parameters of the wireless communication antenna in the power consumption element 23, and the specific value can be set according to the specific performance and parameters of the wireless communication antenna in the power consumption element 23.

In some specific examples, the absence of metal in the specific ellipsoidal spatial range a centered on the electric element 23 may be defined by defining that no metal is included in the specific spatial range B in front of and behind the accommodation groove 300.

Referring to fig. 9, the specific spatial range B of the front and rear sides of the accommodating groove 300 is greater than or equal to the specific ellipsoidal spatial range a centered on the electric element 23.

In some specific examples, the receiving groove 300 is located in the insulation layer 270, and the door inner container 250 is located behind the insulation layer 270, and the chamber of the refrigeration equipment 10 is located behind the door inner container 250.

Generally, the chamber of the refrigeration device 10, the door inner container 250 and the insulation layer 270 do not include metal, so that the rear part of the accommodating groove 300 in the insulation layer 270 does not include metal, and the rear part of the electric element 23 in the accommodating groove 300 does not include metal, so that the wireless signal of the electric element 23 can be prevented from being interfered by metal.

Referring to fig. 8 and 9, the metal plate 240 may be provided with a notch 241 at a portion thereof facing the electric element 23.

In the technical solution provided by the embodiment of the present invention, the size of the notch 241 cannot be too small or too large, and too small may cause the metal plate 240 to greatly interfere with the wireless signal of the electric element 23, and too large may weaken the strength of the metal plate 240, and affect the function of the metal plate as the supporting structure.

Fig. 10 is a schematic projection view of an electric element in the embodiment of the present invention in a plane in which a metal plate is located.

As shown in fig. 10, in some preferred embodiments, an orthographic projection 23' of the power consuming element 23 in the plane S in which the metal plate 240 is located may be located in the notch 241.

In other preferred embodiments, the orthographic projection 23' of the power consuming element 23 in the plane S in which the metal plate 240 is located may also coincide with the notch 241.

In this way, the wireless signal of the electric element 23 can be prevented from being interfered by metal in front of the electric element.

Although the front panel 260 may be disposed in front of the metal plate 240, the front panel 260 is usually made of no metal, for example, it may be made of glass, so that the presence of the front panel 260 does not generate a large interference to the wireless signal of the electric element 23.

In summary, by adopting the above technical solution provided by the embodiment of the present invention, the specific space ranges B at the front and the rear of the accommodating groove 300 do not include metal. Further, the specific space range B in front of and behind the accommodating groove 300 is greater than or equal to the specific ellipsoidal space range a centered on the electric element 23. This ensures that the wireless signal of the electric element 23 is not interfered by a metal object in a spatial range far from the electric element.
