Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration technology, and in particular to a refrigeration device. Background Technology
[0002] Frost typically occurs on the evaporator of refrigeration equipment, especially for air-cooled evaporators. When the ambient temperature is low, the evaporation temperature of the evaporator is also low, making it prone to frost formation on its surface. Frost on the evaporator surface can impede the conduction and dissipation of cold energy, ultimately affecting the cooling performance of refrigeration equipment (such as refrigerators). When the frost layer on the evaporator surface reaches a certain thickness, it not only significantly increases energy consumption but also greatly shortens the lifespan of the refrigeration system. Therefore, it is necessary to defrost the evaporator surface regularly.
[0003] For refrigeration equipment using counter-current defrosting technology, a corresponding piping layout is designed based on its technical characteristics, ultimately resulting in four pipes connected to a four-way valve. During counter-current defrosting, the condenser switches from a heat dissipation device to a cooling device. At this time, the pipes connected to the condenser are low-temperature pipes, causing moisture in the air to condense on these pipes, resulting in ice, frost, and condensation. When the refrigerator switches to normal cooling, the condenser reverts to heat dissipation mode, and the pipes connected to it are high-temperature pipes, melting the frost that condensed in the previous state into water. This water can drip onto the user's floor; furthermore, it may flow to the four-way valve motor, causing an electrical short circuit and rendering the valve malfunction. Utility Model Content

[0046] For ease of description and understanding, the refrigeration equipment is used upright as a reference. The direction facing the user is considered front, and the direction away from the user is considered back. The height of the refrigeration equipment is the vertical direction, and the width of the refrigeration equipment is the horizontal direction. The direction facing the center of the refrigeration equipment is considered inside, and the direction away from the center of the refrigeration equipment is considered outside.
[0047] Figure 1 This is a partial structural schematic diagram of the refrigeration equipment of this utility model. Figure 2 This is a connection block diagram of the first embodiment of the refrigeration system of this utility model.
[0048] See Figure 1 and Figure 2 This embodiment provides a refrigeration device for storing items at low temperatures. The refrigeration device can be a refrigerator, a refrigerated display case, a refrigerated wine cabinet, or a freezer. The refrigeration device includes a cabinet body, a cabinet liner disposed within the cabinet body, a rotatable door covering the cabinet body, and a refrigeration system disposed within the cabinet body.
[0049] The inner liner is located inside the cabinet; the inner liner forms a refrigeration chamber with an open front, where food is placed for low-temperature storage.
[0050] In some embodiments, a shelf is provided inside the liner, which is located in the refrigeration room for carrying items; the refrigeration system is used to provide cooling to the space inside the refrigeration room, so as to provide cooling to the items inside the refrigeration room.
[0051] The cabinet door is closable and closes to the front of the cabinet, allowing the refrigeration compartment inside the cabinet to be opened or closed for placing or removing items. In this embodiment, the cabinet door is rotatable and closes to the front of the cabinet to open and close the refrigeration compartment.
[0052] A cooling duct is formed outside the cabinet outside the cooling room. The cooling duct is used to introduce air from the cooling duct into the cooling room for cooling.
[0053] The refrigeration system transfers cooling energy to the air within the refrigeration duct, providing cool air to the refrigerated rooms so that the air within the refrigeration duct can be cooled. The refrigeration duct can selectively connect with the refrigerated rooms to guide air from the refrigeration duct into the refrigerated rooms, thereby cooling the refrigerated rooms.
[0054] In some embodiments, the refrigeration compartment includes a refrigerator compartment and a freezer compartment, and the refrigeration duct can deliver cooling capacity to the refrigerator compartment and the freezer compartment respectively, so that the air in the refrigeration duct can transfer the cooling capacity to the refrigerator compartment and the freezer compartment respectively, so as to maintain the refrigeration environment in the refrigerator compartment and the freezer compartment.
[0055] There is a foam layer between the inner liner and the outer body of the refrigeration chamber. The foam layer is filled with foam material, which surrounds the upper, lower, left, right and rear side walls of the refrigeration chamber, thereby insulating the refrigeration chamber and maintaining its temperature.
[0056] A refrigeration system is used to release heat from refrigeration equipment into the external environment and to provide cooling to the refrigerated room to maintain a low-temperature environment. The refrigeration system includes components such as a compressor 100, a condenser 200, an evaporator 400, and a capillary tube 300. The compressor 100, condenser 200, capillary tube 300, and evaporator 400 are connected sequentially, and the outlet of the evaporator 400 is connected to the inlet of the compressor 100, thereby forming a channel for refrigerant circulation within the compressor 100, condenser 200, capillary tube 300, and evaporator 400. In this embodiment, the evaporator 400 is disposed within a refrigeration duct.
[0057] The enclosure contains a cooling duct that supplies cold air to the cooling compartment, providing cooling capacity. The refrigeration system exchanges heat with the air within the duct, transferring cooling capacity to the air inside the duct, thus creating cold air within the duct. This cold air is then transferred to the cooling compartment, thereby cooling it.
[0058] The refrigeration duct and the refrigeration chamber are connected, allowing air to circulate between them. This transfers cold air from the refrigeration duct to the refrigeration chamber and heat from the refrigeration chamber to the refrigeration duct. The low-temperature, low-pressure liquid refrigerant in the evaporator 400 exchanges heat with the refrigeration duct and is converted into a low-temperature, low-pressure gaseous refrigerant. This low-temperature, low-pressure gaseous refrigerant in the evaporator 400 is then transported to the compressor 100, where it is compressed into a high-temperature, high-pressure gaseous refrigerant.
[0059] The high-temperature, high-pressure gaseous refrigerant in compressor 100 is delivered to condenser 200, where it releases heat to the surrounding environment, thus converting into a low-temperature, high-pressure liquid refrigerant. This low-temperature, high-pressure liquid refrigerant then undergoes throttling and pressure reduction via capillary tube 300, transforming into a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant is then delivered to evaporator 400 and exchanged with the air in the refrigeration duct.
[0060] The specific structure and connection relationships of the refrigeration system are described in reference to the refrigeration system in related technologies, and will not be repeated here.
[0061] It should be noted that a compressor compartment 101 is formed on the inner bottom of the housing, and the compressor 100 and condenser 200 are installed inside the compressor compartment 101.
[0062] Figure 3 This is a schematic diagram of the structure of the four-way valve of this utility model.
[0063] See Figures 1 to 3 The refrigeration system also includes a four-way valve 500, whose four ports are connected to the compressor 100, condenser 200, and evaporator 400 respectively via pipes. Specifically, the four-way valve 500 includes a valve body 510 and a motor 520. The valve body 510 is configured with four ports, namely the first port 501, the second port 502, the third port 503, and the fourth port 504.
[0064] In some embodiments, the outlet and inlet of the compressor 100 are respectively connected to the first port 501 and the second port 502 of the valve body portion 510 via pipes. The outlet of the compressor 100 is connected to the first port 501 via a pipe, and the inlet of the compressor 100 is connected to the second port 502 via a pipe. The evaporator 400 is connected to the third port 503 of the valve body portion 510 via a pipe; the condenser 200 is connected to the fourth port 504 of the valve body portion 510 via a pipe, and the evaporator 400 and the condenser 200 are connected by a pipe. The four-way valve 500 can selectively open each port via the motor portion 520.
[0065] In one mode, the first interface 501 and the third interface 503 are connected, and the second interface 502 and the fourth interface 504 are connected, so that the medium in the compressor 100 can pass through the four-way valve 500, the condenser 200, the evaporator 400, the four-way valve 500 and the compressor 100 in sequence for refrigeration of the refrigeration equipment.
[0066] In another mode, the first interface 501 and the fourth interface 504 are connected, and the second interface 502 and the third interface 503 are connected, so that the medium in the compressor 100 can pass through the four-way valve 500, the evaporator 400, the condenser 200, the four-way valve 500 and the compressor 100 in sequence for defrosting of the refrigeration equipment.
[0067] In some embodiments, an evaporating dish 600 is provided inside the compressor chamber 101, which can collect and contain defrosting water from the refrigeration equipment. The evaporating dish 600 is located directly below the four-way valve 500, and each interface of the valve body portion 510 is located below the motor portion 520. After the condensation on the outer periphery of the pipes connected to each interface melts, the melted water moves downward under the action of gravity, and the melted water on each pipe will not flow to the motor portion 520, thus ensuring that it will not be damaged and effectively guaranteeing the normal operation of the four-way valve 500.
[0068] In some embodiments, a connecting plate 530 is fixed to the four-way valve 500; the connecting plate 530 is fixed to the bottom wall or side wall of the press chamber 101. The connecting plate 530 facilitates the fixing of the four-way valve 500 inside the press chamber 101.
[0069] See again Figure 2 In the first embodiment of the refrigeration system, the outlet and inlet of the compressor 100 are respectively connected to the first interface 501 and the second interface 502 of the valve body 510 via pipes; the evaporator 400 is connected to the third interface 503 of the valve body 510 via the first pipe 710; the condenser 200 is connected to the fourth interface 504 of the valve body 510 via the second pipe 720; the evaporator 400 and the condenser 200 are connected by pipes. Water melted on the outer periphery of the first pipe 710 and the second pipe 720 can be guided into the evaporating dish 600, effectively preventing the water melted on the first pipe 710 and the second pipe 720 from flowing to the user's base plate or the motor part 520 of the four-way valve 500.
[0070] The first pipe 710 extends from top to bottom into the compressor chamber 101. The portion of the first pipe 710 within the compressor chamber 101 includes a first section and a second section. The second section bends from the lower end of the first section and extends upward, with its upper end connected to the third interface 503. This arrangement ensures that the lowest point of the first pipe 710 within the compressor chamber 101 is located at the junction between the second and first sections. Water on the outer periphery of the first pipe 710 drips from this lowest point into the evaporating dish 600 under gravity, effectively preventing water from flowing onto the four-way valve 500 and protecting the four-way valve 500.
[0071] In some embodiments, the second pipe 720 includes at least a connecting section and a guiding section; the connecting section extends vertically; the upper end of the connecting section is connected to the fourth interface 504; the guiding section extends upward from the lower end of the connecting section and connects to the condenser 200. A low point is formed at the lower end of the connecting section in the second pipe 720, and water on the outer periphery of the second pipe 720 drips from this low point into the evaporating dish 600 under the action of gravity, effectively preventing water outside the second pipe 720 from flowing onto the four-way valve 500, thus protecting the four-way valve 500.
[0072] In some implementations, a condenser-evaporator tube 210 is connected in series between the compressor 100 and the first interface 501. The condenser-evaporator tube 210 is housed in an evaporating dish 600 for the evaporation of water in the evaporating dish 600.
[0073] Figure 4 This is a schematic diagram of the second embodiment of the refrigeration system of this utility model.
[0074] See Figure 4 In the second embodiment of the refrigeration system, the outlet and inlet of the compressor 100 are respectively connected to the first interface 501 and the second interface 502 of the valve body 510 via pipes; the evaporator 400 is connected to the third interface 503 of the valve body 510 via the first pipe 710; the condenser 200 is connected to the fourth interface 504 of the valve body 510 via the second pipe 720; the evaporator 400 and the condenser 200 are connected by pipes. Water melted on the outer periphery of the first pipe 710 and the second pipe 720 can be guided into the evaporating dish 600, effectively preventing the water melted on the first pipe 710 and the second pipe 720 from flowing to the user's base plate or the motor part 520 of the four-way valve 500.
[0075] In the second embodiment of the refrigeration system, the first pipe 710 and the second pipe 720 refer to the structure of the first pipe 710 and the second pipe 720 in the first embodiment of the refrigeration system.
[0076] In some embodiments, a decondensation pipe 810 is provided between the outlet of the compressor 100 and the first interface 501, and the decondensation pipe 810 is located above the compressor compartment 101; one end of the decondensation pipe 810 is connected to the outlet of the compressor 100 through a pipe; the other end of the decondensation pipe 810 is connected to the first interface 501 of the four-way valve 500 through a third pipe 730; the third pipe 730 extends from top to bottom into the compressor compartment 101.
[0077] The defrosting pipe 810 can be used for defrosting the refrigeration compartment and / or the cabinet door. The defrosting pipe 810 is connected to the first interface 501 via a third pipe 730, which extends downwards into the compressor compartment 101. The connection of the third pipe 730 to the first interface 501 ensures that the melted water outside the third pipe 730 can be directed to the evaporating dish 600.
[0078] In some embodiments, the decondensation pipe 810 extends downward and then upward within the compressor chamber 101, and connects to the first interface 501 after extending upward. The lowest point of the decondensation pipe 810 within the compressor chamber 101 is lower than the first interface 501, thereby effectively preventing water on the outer periphery of the decondensation pipe 810 from flowing to the first interface 501, thus protecting the four-way valve 500.
[0079] Figure 5 This is a structural schematic diagram of the third embodiment of the refrigeration system of this utility model.
[0080] See Figure 5 In the third embodiment of the refrigeration system, the outlet and inlet of the compressor 100 are respectively connected to the first interface 501 and the second interface 502 of the valve body 510 via pipes; the evaporator 400 is connected to the third interface 503 of the valve body 510 via the first pipe 710; the condenser 200 is connected to the fourth interface 504 of the valve body 510 via the second pipe 720; the evaporator 400 and the condenser 200 are connected by pipes. Water melted on the outer periphery of the first pipe 710 and the second pipe 720 can be guided into the evaporating dish 600, effectively preventing the water melted on the first pipe 710 and the second pipe 720 from flowing to the user's base plate or the motor part 520 of the four-way valve 500.
[0081] In the third embodiment of the refrigeration system, the first pipe 710 and the second pipe 720 refer to the structure of the first pipe 710 and the second pipe 720 in the first embodiment of the refrigeration system.
[0082] In some embodiments, a return pipe 820 is provided between the inlet of the compressor 100 and the second interface 502, and the return pipe 820 is located above the compressor chamber 101; one end of the return pipe 820 is connected to the inlet of the compressor 100 via a pipe; the other end of the return pipe 820 is connected to the second interface 502 via a fourth pipe 740; the fourth pipe 740 extends downward into the compressor chamber 101. The second interface 502 is located below the motor section 520, thereby effectively preventing melted water outside the fourth pipe 740 from flowing into the motor section 520, thus protecting the four-way valve 500.
[0083] A capillary tube 300 is connected in series between the evaporator 400 and the condenser 200; the outer periphery of the return gas pipe 820 is attached to the outer periphery of the capillary tube 300 so that it can exchange heat with the medium inside the capillary tube 300 and recover the cold and heat inside the capillary tube 300.
[0084] In some embodiments, the return air pipe 820 extends downward and then upward within the compressor chamber 101, and connects to the second interface 502 after extending upward. The lowest point of the return air pipe 820 within the compressor chamber 101 is lower than the second interface 502, thereby effectively preventing water on the outer periphery of the return air pipe 820 from flowing to the second interface 502, thus protecting the four-way valve 500.
[0085] Figure 6 This is a structural schematic diagram of the fourth embodiment of the refrigeration system of this utility model.
[0086] See Figure 6 In the third embodiment of the refrigeration system, the outlet and inlet of the compressor 100 are respectively connected to the first interface 501 and the second interface 502 of the valve body 510 via pipes; the evaporator 400 is connected to the third interface 503 of the valve body 510 via the first pipe 710; the condenser 200 is connected to the fourth interface 504 of the valve body 510 via the second pipe 720; the evaporator 400 and the condenser 200 are connected by pipes. Water melted on the outer periphery of the first pipe 710 and the second pipe 720 can be guided into the evaporating dish 600, effectively preventing the water melted on the first pipe 710 and the second pipe 720 from flowing to the user's base plate or the motor part 520 of the four-way valve 500.
[0087] In the fourth embodiment of the refrigeration system, the first pipe 710 and the second pipe 720 refer to the structure of the first pipe 710 and the second pipe 720 in the first embodiment of the refrigeration system.
[0088] In the fourth embodiment of the refrigeration system, the third pipe 730 refers to the structure of the third pipe 730 in the second embodiment of the refrigeration system. In the fourth embodiment of the refrigeration system, the fourth pipe 740 refers to the structure of the fourth pipe 740 in the third embodiment of the refrigeration system.
[0089] The lowest point of the pipes at each interface of the four-way valve 500 is lower than the four-way valve 500 itself, so that water around the periphery of each pipe will not flow to the four-way valve 500, effectively protecting the four-way valve 500.
[0090] See again Figure 1 The refrigeration equipment also includes a cooling fan 900, which is located inside the compressor compartment 101. Horizontally, a four-way valve 500 is located on the side of the condenser 200 facing away from the cooling fan 900. The arrangement of the four-way valve 500 and its various pipes ensures that the airflow from the cooling fan 900 is not obstructed from reaching the condenser 200, thus enabling better heat dissipation from the condenser 200 and improving the refrigeration efficiency of the equipment.
[0091] In one embodiment, the connecting plate 530 is fixed to the top side wall of the press plate, the connecting plate 530 is arranged vertically, and the four-way valve 500 is arranged vertically to occupy less space in the horizontal direction.
[0092] Figure 7 This is a partial structural schematic diagram of the second embodiment of the refrigeration equipment of this utility model.
[0093] See Figure 7 In the second embodiment of the refrigeration equipment, the connecting plate 530 is fixed to the side wall of the compressor compartment 101, and the connecting plate 530 is inclined toward the condenser 200 in at least one direction from above. The inclined connecting plate 530 drives the four-way valve 500 to be inclined, so as to make full use of the space in the compressor compartment 101 by utilizing the space in the vertical and horizontal directions.
[0094] Figure 8 This is a partial structural schematic diagram of the third embodiment of the refrigeration equipment of this utility model.
[0095] See Figure 8 The refrigeration equipment also includes a cooling fan 900, which is located inside the compressor compartment 101. Horizontally, a four-way valve 500 is positioned between the cooling fan 900 and the condenser 200. The cooling fan 900 controls airflow within the compressor compartment 101, facilitating heat dissipation for the compressor 100 and condenser 200. The four-way valve 500 has downward-facing ports, with corresponding piping connecting upwards to the valve, thus minimizing horizontal space usage and allowing for more horizontal space within the compressor compartment 101 to accommodate other components, fully utilizing the space within the compartment.
