Referring to fig. 1-6, in some embodiments, a refrigeration appliance includes a press housing 100, a first mounting ring 200, a second mounting ring 300, and a first filter 400. The side wall of the press bin 100 is provided with an air inlet 110, a first mounting ring 200 is arranged at the air inlet 110, a second mounting ring 300 is embedded at the inner side of the first mounting ring 200, the outer ring surface of the second mounting ring 300 is detachably connected with the outer ring surface of the first mounting ring 200, the air inlet 110 is blocked by covering the air inlet 110 by a first filter 400, and the edge of the first filter 400 is pressed between the first mounting ring 200 and the second mounting ring 300.

By adopting the refrigeration appliance provided by the embodiment of the disclosure, the first filter 400 is arranged at the air inlet 110 of the press bin 100, so that impurities such as dust in the air flow flowing into the air inlet 110 are filtered, and the pollution of the air flow to the inside of the press bin 100 is reduced. The first mounting ring 200 is disposed at the air inlet 110, the second mounting ring 300 is embedded inside the first mounting ring 200, and the first filter 400 is mounted by sleeving the second mounting ring 300 on the first mounting ring 200. When the first filter 400 is installed, only the first filter 400 is required to be paved on the first mounting ring 200, the second mounting ring 300 is pressed to enable the second mounting ring 300 to be embedded into the first mounting ring 200, and at the moment, the edge of the first filter 400 is pressed in the gap between the first mounting ring 200 and the second mounting ring 300 to complete installation and fixation. When the first filter 400 needs to be disassembled for cleaning or replacement, the extruded first filter 400 can be separated only by taking the second mounting ring 300 out of the first mounting ring 200. The assembling and disassembling efficiency of the first filter 400 at the air inlet 110 can be improved, and the maintenance cost of the refrigeration appliance can be reduced.

Optionally, the refrigerator further comprises a housing 500. The inside of the housing 500 is provided with a refrigerating compartment, and the press house 100 is provided at the bottom of the housing 500. Like this, refrigeration compartment is used for storing articles such as food and is kept fresh, sets up press storehouse 100 in the bottom of casing 500, and press storehouse 100 and refrigeration compartment rationally occupy the inside space of casing 500, have improved the inside space utilization of casing 500.

Optionally, the refrigeration appliance comprises a refrigerator.

Optionally, the refrigeration appliance further comprises a refrigeration system. The refrigerating system is composed of an evaporator, a condenser 120 and a compressor 130, the evaporator is disposed at a rear sidewall of the refrigerating compartment, and the condenser 120 and the compressor 130 are disposed in the press bin 100. In this way, the high-temperature and high-pressure refrigerant flowing out of the compressor 130 flows into the condenser 120 to perform condensation heat release, and the refrigerant after the condensation heat release flows into the evaporator to perform evaporation heat absorption, so that the heat exchange between the evaporator and the refrigerating compartment reduces the ambient temperature in the refrigerating compartment, so that the internal environment of the refrigerating compartment is kept at a low temperature, and the food materials are better stored.

It will be appreciated that the refrigeration system should also include the necessary components of a throttling element, a liquid reservoir, etc., and will not be described in detail herein.

Optionally, both the condenser 120 and the compressor 130 are disposed within the press bin 100. In this way, the air flow flowing in through the air inlet 110 exchanges heat with the condenser 120 and the compressor 130 respectively and then is blown out, so as to dissipate heat of the condenser 120 and the compressor 130, and ensure the normal operation of the refrigeration system.

Optionally, the side wall of the press bin 100 is further provided with an air outlet 140, and the second filter 600 is disposed at the air outlet 140. In this way, the external air flow enters the press bin 100 through the air inlet 110 for heat exchange, and the air flow after heat exchange flows out to the outside through the air outlet 140, so that the heat in the press bin 100 is discharged to the outside. The second filter 600 is disposed at the air outlet 140, so as to reduce the risk of pollution caused by external pollutants such as dust entering the press bin 100 through the air outlet 140.

It is understood that the second filter element 600 is identical to the first filter element 400 in terms of its mounting structure, and will not be described in detail herein.

Optionally, the air inlet 110 and the air outlet 140 are respectively disposed on two opposite sidewalls of the press bin 100. Thus, the air inlet flow flowing in from the air inlet 110 can flow out from the press bin 100 without changing the flowing direction, thereby reducing the loss of air pressure and improving the heat dissipation effect.

Optionally, the flow area of the air inlet 110 and the flow area of the air outlet 140 are the same. In this way, the air inlet 110 and the air outlet 140 are matched, so that the condenser 120 and the compressor 130 in the press bin 100 can be better cooled.

Optionally, the line connecting the center of the air inlet 110 and the center of the air outlet 140 is parallel to the direction of air flow within the press bin 100. Thus, the air inlet flow of the air inlet 110 can more smoothly flow out through the air outlet 140, further reducing the loss of wind pressure and improving the heat dissipation effect.

Optionally, the condenser 120 and the compressor 130 are disposed between the air inlet 110 and the air outlet 140, and the condenser 120 and the compressor 130 are sequentially arranged along the air flow direction in the press bin 100. Thus, the air inlet flow flowing in from the air inlet 110 can better flow through the condenser 120 and the compressor 130, so that the heat exchange efficiency is improved, and the heat dissipation effect is increased. The condenser 120 is used as a main part of the refrigeration system for heat dissipation, and the condenser 120 is arranged on the windward side of the compressor 130, so that the air inlet flow firstly flows through the condenser 120 for heat exchange and then flows through the compressor 130, and meanwhile, the compressor 130 is prevented from blocking the air inlet flow, the heat exchange effect of the condenser 120 is improved, and the normal operation of the refrigeration system is ensured.

Optionally, a heat dissipation fan 150 is further disposed in the press bin 100, the heat dissipation fan 150 is disposed on the leeward side of the compressor 130, the air inlet end of the heat dissipation fan 150 faces the air inlet 110, and the air outlet end faces the air outlet 140. In this way, negative pressure is provided by the operation of the heat dissipation fan 150, so that the air flow sucked into the air inlet 110 exchanges heat, and the air flow after heat exchange can be blown out through the air outlet 140. The heat dissipation fan 150 is arranged on the leeward side of the compressor 130, so that negative pressure generated by the heat dissipation fan 150 can better act on the sides of the compressor 130 and the condenser 120, and meanwhile, the heat dissipation fan 150 is prevented from blocking air inlet flows of the sides of the compressor 130 and the condenser 120.

Optionally, the thickness of the first filter 400 is less than or equal to one third of the thickness of the first mounting ring 200. Thus, the first filter 400 has a larger thickness to form a certain barrier to the air flow, and the second mounting ring 300 is difficult to press into the first mounting ring 200 when the first filter 400 is press-fitted with the first mounting ring 200 and the second mounting ring 300, so that the first mounting ring 200 is broken. Therefore, the thickness of the first filter 400 is set to be less than or equal to one third of the thickness of the first mounting ring 200, which not only can ensure the filtering effect of the first filter 400, but also can reduce the wind resistance of the first filter 400, so that the first filter 400 can be efficiently pressed.

It is understood that the thickness of the first mounting ring 200 refers to the thickness of the first mounting ring 200 in the axial direction of the first mounting ring 200.

Alternatively, the thickness of the first filter 400 is equal to one-fourth of the thickness of the first mounting ring 200. In this way, the thickness of the first filter element 400 is set to be equal to one fourth of the thickness of the first mounting ring 200, so that the filtering effect of the first filter element 400 can be guaranteed, the wind resistance of the first filter element 400 can be reduced, and the first filter element 400 can be efficiently pressed.

Alternatively, the thickness of the first filter 400 is 1mm.

Alternatively, the thickness of the second filter 600 is the same as that of the first filter 400. In this way, the second filter 600 is easily installed and removed.

In one embodiment, the first filter 400 comprises filter cotton. Like this, the filter effect of filter pulp is better, can be efficient filter impurity such as dust in the air inlet air current, reduces the risk of condenser 120 surface area ash.

Optionally, the second filter 600 comprises filter cotton. In this way, the filtering effect of the second filter 600 on the air-out flow can be improved, and the risk of dust in the press house 100 blowing into the external environment can be reduced.

For example, since the refrigerator is mostly placed in an indoor environment for use, the compressor housing 100 continuously sucks in indoor air through the air inlet 110 to exchange heat and then blows the air into the indoor environment again through the air outlet 140. By arranging the filter cotton at the air inlet 110 and the filter cotton at the air outlet 140, indoor air can be purified for a long time, so that impurities such as dust in the indoor air are sucked into the first filter 400 of the air inlet 110 and the second filter 600 of the air outlet 140.

In another embodiment, the first filter 400 includes a filter mesh. Thus, the wind resistance of the filter screen is relatively small while filtering impurities such as dust in the air inlet flow, the influence on the flow of the heat exchange air flow in the press bin 100 is small, and meanwhile, the cost of the filter screen is low, and the cost of frequent replacement and consumption of the first filter 400 is low.

Optionally, the second filter 600 comprises a filter mesh. Thus, the wind resistance of the air outlet air flow is reduced while the impurities such as dust in the air outlet air flow are filtered. The cost can be reduced when the second filter 600 is replaced.

In another embodiment, the first filter 400 at the air inlet 110 is filter cotton, and the second filter 600 at the air outlet 140 is a filter screen. In this way, since the inlet air flow flowing in at the air inlet 110 comes from the outside of the press bin 100, dust and impurities in the inlet air flow are more, and the windward side surface of the condenser 120 is easy to accumulate ash. And the air outlet 140 blows air-out flow from the inside of the press bin 100, so that the air-out flow has less dust and impurity content. Therefore, the first filter 400 at the air inlet 110 is set as filter cotton, and the second filter 600 at the air outlet 140 is set as a filter screen, so that the influence on the heat exchange air flow can be reduced, and the cost is reduced.

Referring to fig. 4, in one embodiment, the first mounting ring 200 is embedded in the air inlet 110, and an outer ring surface of the first mounting ring 200 is connected with an opening edge of the air inlet 110. Thus, when the first mounting ring 200 is embedded in the air inlet 110 and matched with the first mounting ring 200 through the second mounting ring 300, the first mounting ring 200, the second mounting ring 300 and the filter element can be embedded in the plane where the air inlet 110 is located, so that the first mounting ring 200, the second mounting ring 300 and the first filter element 400 are prevented from protruding, and interference with the external environment is avoided.

Optionally, the shape of the first mounting ring 200 is adapted to the air inlet 110, and the shape of the second mounting ring 300 is adapted to the first mounting ring 200. In this way, the first mounting ring 200 can be smoothly embedded in the air inlet 110, and the second mounting ring 300 can be smoothly embedded in the first mounting ring 200 to be matched with the first mounting ring 200 to press-fit the first filter 400.

Optionally, the air inlet 110 has a circular opening structure, and the first mounting ring 200 and the second mounting ring 300 are both circular ring structures. In this way, the connection stability between the first mounting ring 200 and the edge of the air inlet 110 is stronger, and the stress of the first mounting ring 200 and the second mounting ring 300 is more uniform, so that deformation is not easy to occur.

It can be appreciated that the mounting structure at the air outlet 140 is the same as the mounting structure at the air inlet 110, and will not be described here.

In another embodiment, as shown in fig. 5, the first mounting ring 200 is disposed at the air inlet 110, and the projection of the air inlet 110 falls inside the first mounting ring 200 along the direction perpendicular to the plane of the air inlet 110. In this way, the first mounting ring 200 is covered at the air inlet 110, and the projection of the air inlet 110 can fall into the first mounting ring 200, the first mounting ring 200 forms a surrounding structure to the air inlet 110, so that the influence of the first mounting ring 200 on the overflow area of the air inlet 110 can be reduced, and the air intake of the air inlet 110 is ensured.

Alternatively, in the case that the second mounting ring 300 is embedded in the first mounting ring 200, the projection of the air inlet 110 falls inside the second mounting ring 300 in the direction perpendicular to the plane of the air inlet 110. In this way, the second mounting ring 300 can also form a surrounding structure for the air inlet 110, so as to reduce the influence of the second mounting ring 300 on the flow area of the air inlet 110, and further ensure the air intake of the air inlet 110.

In one embodiment, the first mounting ring 200 is removably disposed at the air intake 110. Like this, make first collar 200 can dismantle maintenance and change, can realize the synchronous dismantlement of first collar 200, second collar 300 and first filter 400 through dismantling first collar 200 moreover, when needs are clean first filter 400, also can choose to dismantle first collar 200, avoid dismantling second collar 300 and cause the damage to first filter 400 and lead to first filter 400 unable reuse after clean.

It can be appreciated that the first mounting ring 200 and the air inlet 110 can be connected by a detachable structure such as a fastening slot, which is not described herein.

In a specific embodiment, the outer annular surface of the first mounting ring 200 is detachably connected to the mouth edge of the air inlet 110.

In another specific embodiment, the side wall of the first mounting ring 200 is detachably connected to the inner wall of the press bin 100 corresponding to the periphery of the opening edge of the air inlet 110.

In one embodiment, as shown in connection with fig. 6, the windward side of the second mounting ring 300 is provided with a carrying handle 310. In this way, when the second mounting ring 300 is embedded inside the first mounting ring 200, in order to provide an application point for the disassembly of the second mounting ring 300, the side wall of the second mounting ring 300 is provided with the lifting handle 310, and the second mounting ring 300 can be pulled to be separated from the inner side of the first mounting ring 200 through the lifting handle 310, so that the disassembly efficiency of the second mounting ring 300 is improved.

Optionally, the lifting handle 310 is movably connected to a side wall of the second mounting ring 300, and the lifting handle 310 can move toward or away from the second mounting ring 300. Thus, when the second mounting ring 300 needs to be detached, the lifting handle 310 can be pulled outwards, so that the lifting handle 310 moves back to the second mounting ring 300, the force application area of the lifting handle 310 is increased, and the lifting handle 310 is better operated to pull the second mounting ring 300 from the inner side of the first mounting ring 200. When the second mounting ring 300 is not required to be detached, the lifting handle 310 can be pushed to move towards the second mounting ring 300, so that the protruding length of the lifting handle 310 is reduced, and the risk that the lifting handle 310 interferes with the external environment is reduced.

Optionally, the lift handle 310 includes a sleeve 311 and a telescoping rod 312. One end of the sleeve 311 is embedded in the side wall of the second mounting ring 300, the other end of the sleeve is provided with an opening, one end of the telescopic rod 312, which faces the second mounting ring 300, is embedded in the sleeve 311 in a telescopic manner along the opening, and one end of the telescopic rod 312, which faces the second mounting ring 300, is provided with a limiting part, so that the telescopic distance of the telescopic rod 312 can be limited.
