Detailed Description

The present embodiment provides a refrigerating and freezing apparatus. Fig. 1 is a schematic structural view of a refrigerating and freezing apparatus according to an embodiment of the present invention, and fig. 2 is a schematic partial structural view of the refrigerating and freezing apparatus according to an embodiment of the present invention, and as shown in fig. 1 and 2, the refrigerating and freezing apparatus includes a cabinet 20 and a door 30, a compressor compartment and a storage compartment are provided in the cabinet 20, and the door 30 is used to open and close the storage compartment. The box 20 has a press bottom plate 21 and a press cover plate 22 for defining a compressor bin; the press cover plate 22 is vertically disposed and disposed at one edge of the press base plate 21. Preferably, the compressor bin is disposed at the bottom rear side of the case 20, and the press cover plate 22 is disposed at the rear edge of the press base plate 21.

In order to improve the problem of deformation of the press cover 22 during a drop of the refrigerator freezer, the refrigerator freezer further comprises a guide 30 and at least one energy absorption block 40, as shown in fig. 2 to 4. The guide device 30 is mounted to the case 20 and has at least one guide bar 31, each guide bar 31 having a lower end and an upper end. The lower end of each guide bar 31 is adjacent to the edge, i.e. the lower end of the guide bar 31 is at or near the intersection of the press bottom plate 21 and the press cover plate 22. The lower end of each guide bar 31 passes through the press bottom 21 to allow the above-mentioned edge of the press bottom 21 to move on the guide bar 31. The press cover 22 is provided separately from the press base 21 so that the press cover 22 is arranged not to obstruct the movement of the above-mentioned edge on the guide bar 31. It should be noted that the separation is provided to mean that the two do not hinder the movement of each other. Each energy absorbing block 40 is slidably mounted to a corresponding guide bar 31 on the upper side of the press bottom plate 21, and each energy absorbing block 40 is configured to slide on the corresponding guide bar 31 on the lower side thereof after being subjected to a force from the press bottom plate 21.

When the refrigeration and freezing device provided by the embodiment of the invention falls, the press bottom plate 21 deforms upwards to impact the press cover plate 22, an upward acting force is generated on each energy absorption block 40, each energy absorption block 40 can move along the corresponding guide rod 31, and the falling impact energy is converted into the kinetic energy and the gravitational potential energy of the energy absorption block 40, so that the problem of improving the deformation of the press cover plate 22 is solved. Further, the guide means 30 is plural and is provided at intervals in sequence along the above-mentioned edge.

In some embodiments of the invention, the lower end of the press cover plate 22 has a flap 221, the flap 221 being located on the underside of the press base plate 21. The lower end of each guide bar 31 may be mounted to the flange 221. In some alternative embodiments, the upper end of each guide bar 31 is mounted to the casing 20, such as the bottom steel of the casing 20, and the bottom steel and the structure connected to the bottom steel are disposed on the upper side of the compressor to separate the compressor compartment from the foaming layer of the casing 20.

The press base plate 21 includes a connecting plate portion 211, the connecting plate portion 211 having the above-described edge, and the connecting plate portion 211 being higher than the lowest position of the press base plate 21. That is, the above-mentioned edge of the press base 21 is disposed at a distance from the lowest position of the press base 21. The press bottom plate 21 further comprises a flange arranged at the edge and located inside the press cover plate 22. The provision of the flange 221 and/or the flange enables the press base plate 21 and the press cover plate 22 to close the compressor compartment and enables the press base plate 21 and the press cover plate 22 to be arranged separately.

In some embodiments of the invention, each energy absorbing block 40 is magnetically attached to the housing 20. For example, each energy absorbing block 40 may be an energy absorbing iron piece, and a magnet is mounted to the lower end of each guide bar 31. Also for example, each energy absorbing block 40 is a magnet block; the press bottom plate 21 may be made of a magnetic material, or an iron piece may be provided on the press bottom plate 21. In some embodiments of the present invention, a damping fluid is disposed within each guide rod 31 to increase the conversion of fall impact energy into kinetic, gravitational potential, and internal energy, among others.

In some embodiments of the present invention, each guide 30 has two guide rods 31, and the upper ends of the two guide rods 31 are connected together. For example, each guide bar 31 includes a vertical section, and an arc-shaped section provided at an upper end of the vertical section and bent toward the other guide bar 31. The refrigerating and freezing device further comprises a first deformation energy absorption device 50 which is arranged between the two energy absorption blocks 40 and is arranged on the two guide rods 31. The first deformation energy absorption device 50 is a spring. In some alternative embodiments of the present invention, the refrigeration and freezing apparatus further comprises at least one second deformation energy absorbing device, each second deformation energy absorbing device is disposed on the upper side of one energy absorbing block 40, and the upper end of each second deformation energy absorbing device is fixedly disposed. The second deformation energy absorption device can be a spring. The first deformation energy-absorbing device 50 or the second deformation energy-absorbing device can convert the falling impact energy into deformation energy, such as elastic potential energy.
