[0034] Refrigeration equipment includes refrigerators, freezers, refrigerators and other equipment, which can generate cold air to refrigerate and freeze items to extend the shelf life of items.

[0035] The refrigeration device may include a housing, a refrigeration system and a controller. A refrigeration compartment may be provided on the front side of the housing for accommodating articles. A press chamber may be provided on the rear side of the housing. At least part of the refrigeration system may be accommodated in the press chamber. The refrigeration system is capable of generating cold energy and providing the cold energy to the refrigeration compartment, thereby refrigerating or freezing articles in the refrigeration compartment. The controller may be accommodated in the housing, and the controller may be electrically connected to the refrigeration system so as to be able to control the operation of the refrigeration system.

[0036] However, during the operation and defrosting process of the refrigeration system, the humidity and temperature in the compressor compartment can rise. When the controller is running, it will also generate a lot of heat, which will cause the temperature in the compressor compartment to rise. The high temperature and high humidity environment in the compressor compartment will affect the operation of the refrigeration system, reduce the refrigeration efficiency of the refrigeration system, and corrode the controller and refrigeration system, reducing the service life of the refrigeration system and the controller.

Figure 4 yes Figure 2 The structure shown in FIG. 1 is a schematic diagram of the structure after removing the press cover plate.

[0040] See also Figures 1 to 4 The utility model provides a refrigeration device, which may include: a housing 100, a refrigeration system 200, a controller (not shown in the figure), a press cover plate 300 and a ventilation channel 400. The peripheral side of the housing 100 may be opened to form a press chamber 120. The refrigeration system 200 may be at least partially located in the press chamber 120. The controller may be accommodated in the press chamber 120, and the controller may be electrically connected to the refrigeration system 200 to control the operation of the refrigeration system 200. The press cover plate 300 may be covered on the press chamber 120, and an air outlet 310 may be opened in the middle of the press cover plate 300. The press cover plate 300 may be provided with an exhaust fan 320 at the air outlet 310. The exhaust fan 320 may be electrically connected to the controller so that the controller can control the operation of the exhaust fan 320. Air inlets 330 may be opened on both sides of the length direction of the press cover plate 300. The air outlet 310 may be located between the two air inlets 330. The ventilation channel 400 may be accommodated in the press chamber 120. An air inlet 430 may be opened in the press chamber 120 at one end of the ventilation channel 400, and an exhaust port 440 may be opened toward the press cover plate 300 at the other end of the ventilation channel 400, and the exhaust port 440 may be connected to the air outlet 310 of the press cover plate 300, so that the ventilation channel 400 can discharge the gas in the press chamber 120 to the outside through the air inlet 430, the exhaust port 440, and the air outlet 310.

[0041] When the refrigeration equipment is in use, the controller can control the exhaust fan 320 to start up to extract the gas in the compressor chamber 120 to the outside.

[0042] When the exhaust fan 320 is started, the outside air enters the compressor chamber 120 through the air inlets 330 on both sides. After entering the compressor chamber 120, the outside air flows toward the air inlet 430 to drive the high-temperature and high-humidity gas in the compressor chamber 120 into the ventilation channel 400. Afterwards, under the action of the exhaust fan 320, the high-temperature and high-humidity gas is discharged to the outside through the exhaust port 440 of the ventilation channel 400 and the air outlet of the compressor cover plate 300, thereby effectively reducing the temperature and humidity in the compressor chamber 120, ensuring the safe and stable operation of the refrigeration system 200 and the controller, preventing the refrigeration system 200 and the controller from being corroded, and extending the service life of the refrigeration system 200 and the controller.

[0043] See also Figures 2 to 4 In this embodiment, the front side of the housing 100 may be opened to form a refrigeration compartment 110 for accommodating items. The rear side of the housing 100 may be opened to form a press chamber 120, which may be used to accommodate at least part of the refrigeration system 200 and the controller.

[0044] In some embodiments, the press chamber 120 can also be disposed on the left or right side of the housing 100 .

Figure 6 It is a structural schematic diagram of a press cover plate of the utility model. Figure 7 It is a structural schematic diagram of the press cover plate of the utility model from another perspective.

[0046] See also Figures 2 to 7 In this embodiment, the refrigeration device may include a press cover plate 300. The press cover plate 300 may be disposed on the rear side of the housing 100. The press cover plate 300 may be an openable cover disposed on the press bin 120. The press cover plate 300 may extend in the left and right directions. An air outlet 310 may be provided in the middle of the press cover plate 300 to discharge the gas in the press bin 120. Air inlets 330 may be provided on both sides of the length direction of the press cover plate 300 to allow external gas to enter the press bin 120.

[0047] See also Figures 2 to 7 In this embodiment, the air outlet 310 can be located between the two air inlets 330 so as to divide the compressor chamber 120 into two parts, left and right. When the outside gas enters the compressor chamber 120 through the air inlets 330 on both sides, the gas can flow toward the ventilation channel 400 in the middle, and finally be discharged to the outside through the air outlet 310 under the action of the exhaust fan 320. The setting of the air outlet 310 and the two air inlets 330 can divide the total flow of the gas into two parts, left and right, so as to effectively reduce the flow length of the gas on both sides, thereby improving the flow efficiency of the gas and improving the discharge efficiency of the high-temperature and high-humidity gas in the compressor chamber 120.

[0048] See also Figures 5 to 7 In this embodiment, the press cover plate 300 may be provided with mesh covers 331 at the two air inlets 330. The mesh covers 331 can effectively prevent foreign debris from entering the press chamber 120, thereby ensuring the safety of various components in the press chamber 120.

[0049] In some embodiments, the press cover plate 300 can be integrally formed with the mesh cover 331. In other embodiments, a plurality of air intake micro holes are provided on both sides of the press cover plate 300. The plurality of air intake micro holes are arranged in an array. The plurality of air intake micro holes are combined to form an air inlet 330 for external air to enter the press chamber 120.

[0050] See also Figures 5 to 7 In this embodiment, the press cover plate 300 may be provided with an exhaust fan 320 at the air outlet 310. The exhaust fan 320 can realize the gas exchange between the gas in the press chamber 120 and the external gas.

[0051] The exhaust fan 320 can be arranged at the junction of the inside of the compressor chamber 120 and the outside. According to the Bernoulli principle, due to the high gas flow rate at the exhaust fan 320, a low pressure area is formed at the exhaust fan 320. The low pressure area at the exhaust fan 320 causes the gas in the compressor chamber 120 to flow toward the air inlet 430 of the ventilation channel 400 under the action of negative pressure suction, and then be discharged to the outside through the exhaust port 440 and the air outlet 310.

[0052] In addition, the exhaust fan 320 is arranged at the junction of the inside of the compressor chamber 120 and the outside. When the gas in the compressor chamber 120 flows toward the ventilation channel 400, the refrigeration system 200 and the controller in the compressor chamber 120 do not affect the flow of the gas, and the gas will not impact the refrigeration system 200 and the controller, thereby reducing the kinetic energy loss during gas flow, ensuring the flow rate of the gas in the compressor chamber 120, and improving the cooling and dehumidification efficiency in the compressor chamber 120.

[0053] In some embodiments, the exhaust fan 320 may be an axial flow fan.

[0054] In other embodiments, the exhaust fan 320 can be disposed at the exhaust port 440 of the ventilation channel 400, and the left and right side walls of the exhaust fan 320 can abut against the two inner side walls of the ventilation channel 400. The exhaust fan 320 is connected to the press cover plate 300 to cover the air outlet 310.

[0055] Figure 8 yes Figure 7 Schematic diagram of part of the structure shown in . Fig. 9 It is a structural schematic diagram of a press bin of the utility model. Fig.10It is a structural schematic diagram of the utility model in which the upper side wall and the front side wall are removed from the press chamber.

[0056] See also Figure 4 , Figures 6 to 10 In this embodiment, the refrigeration device may include a ventilation channel 400. The ventilation channel 400 may be accommodated in the press chamber 120. The ventilation channel 400 may extend in the front-to-back direction. An air inlet 430 and an air outlet 440 may be respectively provided at both ends of the ventilation channel 400. The air inlet 430 of the ventilation channel 400 may be located in the press chamber 120 so that the gas in the press chamber 120 can enter the ventilation channel 400 through the air inlet 430. The air outlet 440 of the ventilation channel 400 may be connected to the air outlet 310 so that the gas in the ventilation channel 400 can be discharged to the outside under the action of the exhaust fan 320.

[0057] In some embodiments, the air inlet 430 of the ventilation channel 400 may extend deep into the interior of the press chamber 120. A side wall of the press chamber 120 relative to the press cover plate 300 is a guide wall 121, that is, the front side wall of the press chamber 120 is a guide wall 121. A ventilation gap 122 may be provided between the air inlet 430 of the ventilation channel 400 and the guide wall 121.

[0058] The setting of the ventilation gap 122 can further increase the gas flow speed at the intersection of the ventilation channel 400 and the compressor chamber 120, so that the gas in the compressor chamber 120 can flow into the ventilation channel 400 more efficiently and finally be discharged to the outside through the exhaust port 440 and the air outlet 310.

[0059] See also Figure 4 , Figures 6 to 10 In this embodiment, the ventilation channel 400 may include two side plates 410, a bottom plate 420 and a top plate. The two side plates 410, the bottom plate 420 and the top plate may all extend in the front-rear direction. The two side plates 410 may be arranged at intervals in the left-right direction. The bottom plate 420 and the top plate may both be located between the two side plates 410. The bottom plate 420 may be connected to the lower portion of the beam side plates 410. The top plate may be connected to the upper portion of the two side plates 410.

[0060] In some embodiments, the top plate may overlap with the upper side wall of the press chamber 120 , that is, the upper side wall of the press chamber 120 , the two side walls, and the bottom plate 420 are combined to form the ventilation channel 400 .

[0061] In some embodiments, in a plane perpendicular to the axis of the air outlet 310, the projection of the exhaust fan 320 may be located within the enclosed range of the projection of the ventilation channel 400 to ensure the exhaust efficiency of the exhaust fan 320. Since the air outlet 310 is smaller than the size of the ventilation channel 400, the air outlet 310 forms a low-pressure area under the action of the exhaust fan 320, so that the gas in the ventilation channel 400 can flow quickly toward the low-pressure area, so as to improve the exhaust efficiency of the ventilation channel 400 and improve the cooling and dehumidification efficiency of the compressor chamber 120.

[0062] In some embodiments, the rear end of the ventilation channel 400 can be attached to and connected to the press cover plate 300 to prevent the gas in the press chamber 120 from flowing to the air outlet 310 through the gap between the ventilation channel 400 and the press cover plate 300, thereby ensuring that the gas in the front and rear of the press chamber 120 is discharged to the outside through the ventilation channel 400, thereby improving the cooling and dehumidification efficiency in the press chamber 120, and ensuring the reliability and stability of cooling and dehumidification.

[0063] See also Figure 4 , Figures 6 to 10 In this embodiment, the refrigeration device may include a refrigeration system 200. At least a portion of the refrigeration system 200 may be accommodated in the press chamber 120.

[0064] The refrigeration system 200 may include a condenser 210. The condenser 210 may be housed in the compressor chamber 120. The condenser 210 may be disposed close to a side wall of the ventilation passage 400. On the one hand, the condenser 210 generates heat during operation. When the outside air flows from the air inlet 330 toward the air inlet 430, the outside air can take away part of the heat and be discharged to the outside through the ventilation passage 400 to reduce the temperature in the compressor chamber 120. On the other hand, the heat generated by the condenser 210 during operation can be partially transferred to the side wall of the ventilation passage 400, and the heat on the ventilation passage 400 can be further reduced under the flow of gas, thereby further reducing the temperature in the compressor chamber 120.

[0065] In some embodiments, the condenser 210 may be disposed in contact with a side wall of the ventilation passage 400 .

[0066] See also Figure 4 , Figures 6 to 10In this embodiment, the refrigeration system 200 may further include an evaporator (not shown in the figure). The evaporator may be arranged on the side of the condenser 210 away from the ventilation channel 400. The evaporator may be arranged opposite to an air inlet 330 of the compressor cover plate 300. When the external gas enters the compressor chamber 120 from the air inlet 330, the gas flows through the evaporator, and the gas can absorb part of the cold on the evaporator. After that, the gas flows through the condenser 210 so that part of the cold in the gas can cool the condenser 210. Finally, the gas after flowing through the condenser 210 flows into the air inlet 430 of the ventilation channel 400, and is discharged to the outside along the ventilation channel 400 and the air outlet 310. The setting position of the evaporator, the condenser 210 and the ventilation channel 400 can effectively improve the energy utilization rate of the refrigeration system 200 and improve the cooling efficiency of the compressor chamber 120.

[0067] See also Figure 4 , Figures 6 to 10 In this embodiment, the refrigeration system 200 may further include a compressor 230. The compressor 230 may be disposed on a side of the ventilation passage 400 away from the condenser 210. The compressor 230 may be located between the air inlet 330 and the air outlet 310. When external air enters the compressor chamber 120 through the air inlet 330, the external air can flow on the surface of the compressor 230, thereby reducing the temperature of the surface of the compressor 230. In addition, the external air can also drive the high-temperature and high-humidity gas in the compressor chamber 120 to flow toward the ventilation passage 400, so as to be discharged to the outside through the ventilation passage 400, thereby reducing the temperature and humidity in the compressor chamber 120.

[0068] In some embodiments, the compressor 230 may be located between the left air inlet 330 and the ventilation passage 400 , and the condenser 210 and the evaporator may be located between the ventilation passage 400 and the right air inlet 330 .

[0069] See also Figure 4 , Figures 6 to 10 In this embodiment, a water box 130 may be further provided in the compressor chamber 120. The water box 130 may be located below the evaporator. The water box 130 may carry condensed water generated when the refrigerator is running. The water box 130 may also carry defrosting water generated when the refrigerator is defrosted.

[0070] When the exhaust fan 320 is running, external air can flow through the surface of the water box 130 to partially convert the water in the water box 130 into water vapor, and finally discharge it to the outside through the ventilation channel 400, thereby effectively reducing the humidity in the water box 130.

[0071] In some embodiments, the water box 130 extends along the length direction of the press cover plate 300. In a plane perpendicular to the up-down direction, the projection of the ventilation channel 400 is located within the enclosed range of the projection of the water box 130. The external air entering through the air inlets 330 on both sides can flow over the water box 130, so that the water in the water box 130 is converted into water vapor and discharged to the outside, thereby improving the dehumidification efficiency of the press chamber 120.

[0072] In this embodiment, a temperature sensor (not shown in the figure) may be provided in the press chamber 120. The temperature sensor can detect a temperature signal in the press chamber 120. The temperature sensor can be electrically connected to the controller and transmit the temperature signal to the controller.

[0073] In some embodiments, when the temperature sensor detects that the temperature in the press bin 120 is low, the temperature sensor transmits a temperature signal to the controller, so that the controller can control the exhaust fan 320 to stop running according to the temperature signal, thereby reducing the energy cost of the refrigeration equipment. When the temperature sensor detects that the temperature in the press bin 120 is high, the controller can control the exhaust fan 320 to run after receiving the temperature signal, so as to reduce the temperature and humidity in the press bin 120.

[0074] In other embodiments, the controller can preset multiple temperature ranges, and different temperature ranges correspond to different rotation speeds of the exhaust fan 320. When the controller determines that the temperature signal transmitted by the temperature sensor belongs to a certain temperature range, the controller can control the rotation speed of the exhaust fan 320 to change. When the rotation speed of the exhaust fan 320 increases, the exhaust volume of the exhaust fan 320 can be increased, thereby improving the cooling and dehumidification efficiency of the compressor chamber 120.

[0075] In this embodiment, a humidity sensor (not shown in the figure) may be provided in the press chamber 120. The humidity sensor can detect a humidity signal in the press chamber 120. The humidity sensor can be electrically connected to the controller and transmit the humidity signal to the controller.

[0076] In some embodiments, when the humidity sensor detects that the humidity in the press chamber 120 is low, the humidity sensor transmits a humidity signal to the controller, so that the controller can control the exhaust fan 320 to stop running according to the humidity signal, thereby reducing the energy cost of the refrigeration equipment. When the humidity sensor detects that the humidity in the press chamber 120 is high, the controller can control the exhaust fan 320 to run after receiving the humidity signal, so as to reduce the humidity and humidity in the press chamber 120.

[0077] In other embodiments, the controller can preset multiple humidity ranges, and different humidity ranges correspond to different rotation speeds of the exhaust fan 320. When the controller determines that the humidity signal transmitted by the humidity sensor belongs to a certain humidity range, the controller can control the rotation speed of the exhaust fan 320 to change. When the rotation speed of the exhaust fan 320 increases, the exhaust volume of the exhaust fan 320 can be increased, thereby improving the cooling and dehumidification efficiency of the compressor chamber 120.

[0078] See also Figures 1 to 10 In the present invention, when the refrigeration equipment is in use, the operation and defrosting process of the refrigeration system 200 can increase the humidity and temperature in the compressor bin 120, and the controller can increase the temperature in the compressor bin 120. At this time, the controller can control the exhaust fan 320 to operate to extract the gas in the ventilation channel 400 and discharge it to the outside.

[0079] When the exhaust fan 320 is in use, the outside air enters the compressor chamber 120 through the air inlets 330 on both sides, and flows toward the air inlet 430 of the ventilation channel 400 under the action of the negative pressure suction at the exhaust fan 320. On the one hand, when the air flows in the compressor chamber 120, the high-temperature and high-humidity air in the compressor chamber 120 can be brought into the ventilation channel 400, and finally discharged to the outside through the exhaust port 440 and the air outlet 310, so as to effectively reduce the temperature and humidity in the compressor chamber 120, ensure the safe and stable operation of the refrigeration system 200 and the controller, and prevent moisture from corroding the controller.

[0080] On the other hand, the exhaust fan 320 is arranged on the press cover plate 300, which can realize the gas circulation between the press chamber 120 and the external environment. When the gas flows in the press chamber 120, the exhaust flow rate at the air outlet 310 will not be affected by various equipment components in the press chamber 120, thereby ensuring the exhaust efficiency.

[0081] Although the present application has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present application can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
