Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment, and more particularly to a refrigeration equipment with a return gas pipe assembly. Background Technology

[0002] As people's living standards improve, the use of household refrigeration equipment is becoming increasingly widespread. Because the indoor temperature of a refrigerated room is usually much lower than the ambient temperature surrounding the refrigeration equipment, condensation often occurs during operation, negatively impacting user experience.

[0003] Whether condensation occurs in refrigeration equipment is mainly related to two factors: the surface temperature of the equipment and the relative humidity of the outside air. During operation, users have observed condensation on the surface of the capillary tubes inside the compressor compartment. For users in the Yangtze River basin and coastal areas, the high humidity, especially during the rainy season when it can reach up to 90%, causes severe condensation on the capillary tubes, even forming on the return pipe. This condensation drips onto the compressor support plate, creating a safety hazard. Summary of the Invention

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0019] It should be understood that terms such as "upper," "lower," "outer," and "inner," used herein to indicate spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms "spatial relative position" may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0020] The present invention discloses a refrigeration device, which includes a box body, the inside of which is filled with a foam layer 1 to form a storage chamber.

[0021] Specifically, the refrigeration equipment can be any product that provides refrigeration and storage functions for users, such as refrigerators, freezers, and wine cabinets. The cabinet includes an outer shell and an inner liner, with a foam layer 1 filling the space between the outer shell and the inner liner. This foam layer can be polyurethane foam or other materials that can provide insulation for the refrigeration equipment.

[0022] The enclosure defines storage compartments for placing items. The number of storage compartments can be adjusted according to user needs. The refrigeration conditions of different storage compartments can be adjusted according to user needs, such as setting different refrigeration temperatures to meet different storage conditions. Specifically, these can be refrigerator compartments, variable temperature compartments, freezer compartments, etc.

[0023] The refrigeration equipment also includes a door, which is used to open and close the cabinet to create a sealed environment, maintain the temperature of the storage room, and facilitate users to put and take items in the storage room.

[0024] The refrigeration equipment also includes a refrigeration system and a return gas pipe assembly 100, wherein the refrigeration system includes at least a compressor, a condenser, and an evaporator. Figure 1 As shown, the return air pipe assembly 100 includes a return air pipe 3 and a capillary tube 5.

[0025] In this embodiment of the invention, the refrigeration system further includes a dryer filter, and the compressor, condenser, dryer filter, capillary tube 5, and evaporator are connected in sequence. One end of the return gas pipe 3 is connected to the evaporator, and the other end is connected to the compressor.

[0026] Specifically, such as Figure 2As shown, the return air pipe 3 includes a first section 301 embedded in the foam layer 1 and a second section 303 that passes through the foam layer 1 and is connected to the compressor. The capillary tube 5 includes a winding portion 501 that wraps around the outer surface of the first section 301, so that the capillary tube 5 with a temperature difference and the return air pipe 3 can exchange heat in the foam layer 1. Compared with the conventional solution of setting the heat exchange point at the engine compartment partition, this further increases the temperature of the capillary tube surface and avoids condensation in the capillary tube inside the engine compartment, thereby solving the safety hazards caused by capillary tube condensation.

[0027] In this embodiment of the invention, the compressor is installed in a compressor compartment with a partition 7. The partition 7 has partition holes through which the return gas pipe assembly passes. The foam layer 1 fills the compressor compartment. The second section 303 of the return gas pipe 3, which is connected to the compressor, is located in the compressor compartment.

[0028] like Figure 2-5 As shown, the first section 301 of the return pipe 3 includes a heat exchange section 3001 wound by the winding part, and a connecting section 3003 connecting the heat exchange section 3001 and the second section 303. Specifically, the heat exchange section 3001, the connecting section 3003, and the second section 303 are connected in sequence. The heat exchange section 3001 and the connecting section 3003 are both located inside the foaming layer 1, while the second section 303 is located inside the compressor chamber outside the foaming layer 1.

[0029] Furthermore, the connecting section 3003 and the second section 303 are fitted with a first heat shrink tubing 9. The first heat shrink tubing 9 can be made of PVC, and its inner diameter matches the outer diameter of the return air pipe, so that the inner wall of the first heat shrink tubing 9 is simultaneously fitted to the outer walls of both the connecting section 3003 and the second section 303. This fitted first heat shrink tubing 9 improves the thermal conductivity of the return air pipe 3 surface, reduces condensation in the return air pipe 3 within the compressor chamber, and eliminates the safety hazards caused by condensation in the return air pipe assembly 100.

[0030] In an embodiment of the present invention, the first heat shrink tube 9 of the connecting section 3003 is covered with a first insulation tube 11, the inner diameter of the first insulation tube 11 matches the outer diameter of the heat shrink tube, and the inner wall of the first insulation tube 11 is fitted to the outer wall of the heat shrink tube 9.

[0031] In addition, such as Figure 6 As shown, the first heat shrink tube 9 of the second segment 303 is covered with a second insulation tube 13. The inner diameter of the second insulation tube 13 matches the outer diameter of the first heat shrink tube 9, and the inner wall of the second insulation tube 13 is fitted to the outer wall of the first heat shrink tube 9.

[0032] Furthermore, a rubber plug 15 with a through hole is provided between the first insulation pipe 11 and the second insulation pipe 13. The rubber plug 15 is sealed and fixed on the partition hole, and the capillary tube 5 and the return air pipe 3 pass through the through hole and enter the compressor chamber.

[0033] In an embodiment of the present invention, the capillary tube 5 further includes a fixing portion 503 wrapped around the outer surface of the first insulation tube 11 and an extension portion 505 passing through the rubber plug 15 and entering the compressor chamber. One end of the extension portion 505 is connected to the dryer filter in the refrigeration system. Both the fixing portion 503 and the extension portion 505 are fitted with a tightly fitting second heat shrink tubing 17. The second heat shrink tubing 17 fitted to the capillary tube 5 improves the thermal conductivity of the capillary tube 5 surface, further reduces the condensation problem of the capillary tube 5 in the compressor chamber, and eliminates the safety hazards caused by condensation of the capillary tube 5.

[0034] Specifically, the second heat shrink tubing 17 can be made of PVC material, and the first insulation tube 11 and the second insulation tube 13 can be made of rubber and plastic tubing. The diameter of the rubber and plastic tubing can be selected according to the outer diameter of the first heat shrink tubing 9, so that the first insulation tube 11 and the second insulation tube 13 are tightly fitted to the first heat shrink tubing 9. At the same time, both ends of the first insulation tube 11 and the second insulation tube 13 are fixed to the return air tube 3 by cable ties 19.

[0035] In this embodiment of the invention, the connecting section 3003 and the second section 303 of the return air pipe 3 are fitted with a tightly fitting first heat shrink tube 9. The first heat shrink tube 9 in the foam layer 1 is fitted with a tightly fitting first insulation tube 11. The fixing part 503 of the capillary tube 5 is wrapped around the outer surface of the first insulation tube 11. The first insulation tube 11 set in the foam layer 1 not only plays the role of heat preservation of the return air pipe, but also plays the role of separating and fixing the return air pipe assembly 100.

[0036] Furthermore, a second insulating tube 13 is tightly fitted onto the first heat shrink tubing 9 inside the press chamber. Simultaneously, a rubber plug 15 with a through hole is installed between the first insulating tube 11 and the second insulating tube 13. The rubber plug 15 is sealed within the partition hole, allowing the return air pipe assembly 100 within the foam layer to enter the press chamber through the through hole. The second insulating tube 13 insulates the return air pipe 3 inside the press chamber, further reducing condensation on the return air pipe 3 in conjunction with the first heat shrink tubing 9, thus eliminating the safety hazard caused by condensation on the return air pipe assembly 100.
