Detailed Description

In order to make the present utility model better understood by those skilled in the art, the following description of the present utility model will be made in detail with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which a person skilled in the art would obtain without making any inventive effort, are within the scope of the utility model.

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1 to 3, an embodiment of the present utility model proposes a refrigeration apparatus 10, where the refrigeration apparatus 10 may be an ice chest or a container, and the refrigeration apparatus 10 may include a cabinet 20 and a refrigeration system 100, and the refrigeration system 100 may be located in the cabinet 20, so as to facilitate refrigeration of the refrigeration system 100 in the cabinet 20.

Referring to fig. 3 and 4, the refrigeration system 100 may include a freezing evaporator 110, a compressor 120, a condenser 130, and a first throttling device 140, and the freezing evaporator 110, the compressor 120, the condenser 130, and the first throttling device 140 may be sequentially connected through refrigerant lines such that the freezing evaporator 110, the compressor 120, the condenser 130, and the first throttling device 140 form the first refrigeration cycle 101.

The freeze evaporator 110 may evaporate a liquid refrigerant into a gaseous refrigerant and absorb heat. The compressor 120 can compress the gaseous refrigerant to change the low-pressure gaseous refrigerant into the high-pressure gaseous refrigerant, so as to help the refrigerant to provide heat absorption from the high-temperature environment and heat release to the low-temperature environment, and to help the circulation of the refrigerant to be smooth. The compressor 120 may be a scroll compressor or a rotor compressor. The condenser 130 may condense the gaseous refrigerant into a liquid refrigerant and emit heat. The first throttling device 140 may be a capillary tube or an expansion valve, and the first throttling device 140 may change the high-pressure liquid refrigerant into a low-temperature low-pressure liquid refrigerant. The first throttling device 140 may reduce the pressure of the refrigerant so that the refrigerant can absorb heat from the air and evaporate normally.

The refrigeration system 100 may further include a second throttling device 150 and a refrigeration evaporator 160, and the second throttling device 150 and the refrigeration evaporator 160 may be disposed in parallel with the first throttling device 140, with the second throttling device 150, the refrigeration evaporator 160, the refrigeration evaporator 110, the compressor 120, and the condenser 130 forming the second refrigeration cycle 102.

The refrigeration system 100 may further include a three-way valve 170, where the three-way valve 170 may be connected to a refrigerant line connection between the condenser 130, the first throttling device 140 and the second throttling device 150 through a refrigerant line, so as to control a flow direction of the refrigerant flowing out of the condenser 130, thereby controlling the operation conditions of the first refrigeration cycle 101 and the second refrigeration cycle 102.

The refrigeration system 100 may also include a refrigeration fan 180, where the refrigeration fan 180 may drive air to the refrigeration evaporator 160, accelerating the efficiency of the heat exchange of the air with the refrigeration evaporator 160.

Taking the second refrigeration cycle 102 as an example, when the refrigeration system 100 is refrigerating for a long time, the temperature of the refrigeration space 202 is low, typically lower than 0 ℃, the refrigerant in the refrigeration evaporator 160 is required to continue absorbing heat, and the temperature of the refrigerant in the refrigeration evaporator 160 should be lower than the temperature of the air in the refrigeration space 202, so the temperature of the refrigerant in the refrigeration evaporator 160 is also lower than 0 ℃. Also, the air in the refrigerated space 202 tends to contain moisture, and the moisture of the air in the refrigerated space 202 may freeze when it hits the refrigeration evaporator 160 below 0 ℃ to form frost.

When the refrigeration evaporator 160 is in the defrosting state, that is, the second refrigeration cycle 102 stops running (the refrigerant is not circulated any more), the refrigeration fan 180 operates, so that the air is driven to flow to the refrigeration evaporator 160, thereby defrosting the refrigeration evaporator 160, so that the air flowing to the refrigeration evaporator 160 for defrosting is more moist, and at the moment, the air in the cabinet 20 is more moist.

The specific structure of the cabinet 20 can refer to the following embodiments, and since the refrigeration device 10 adopts all the technical solutions of all the embodiments described below, at least has all the beneficial effects brought by the technical solutions of the embodiments described below, and will not be described in detail herein.

Referring to fig. 2 and 4, the embodiment of the present utility model further provides a cabinet 20, where the cabinet 20 may be applied to a refrigeration device 10, and the refrigeration device 10 may be a refrigerator or a container. In the following embodiments, the cabinet 20 is mainly used for a refrigerator, and other cases requiring the cabinet 20 may be referred to for implementation.

Referring to fig. 2 to 6, the cabinet 20 may include a case 200 and a moisturizing drawer 300, the case 200 may have a refrigerating compartment 201, a refrigerating space 202, and a humidifying air duct 203, and an air inlet 203a of the humidifying air duct 203 may be communicated with the refrigerating space 202. The moisturizing drawer 300 may be located in the refrigerator compartment 201, the moisturizing drawer 300 may include a drawer body 310 and a moisturizing film 320, the moisturizing film 320 may be provided to the drawer body 310, the humidification duct 203 may be adapted to guide air of the refrigerating space 202 to the moisturizing film 320, for example, an air outlet 203b of the humidification duct 203 may be adapted to guide air of the refrigerating space 202 to the moisturizing film 320. So, humidification wind channel 203 can be with the comparatively moist air water conservancy diversion of refrigeration space 202 to moisturizing film 320, moisturizing film 320 can collect the comparatively moist moisture of air from humidification wind channel 203 to and adjust drawer body 310's moisture, and moisturizing film 320 has the effect of keeping out the wind, helps avoiding humidification wind channel 203 direct air supply to drawer body 310's inside, reduces the risk that the moisture of the fruit vegetables that moisturizing drawer 300 stored was taken away to the air, makes moisturizing drawer 300 have good humidity under the regulation of moisturizing film 320, thereby has improved refrigeration plant 10's fresh-keeping effect, and then has improved user experience and feel.

In addition, the humidity of the moisturizing drawer 300 can be adjusted by the moisturizing film 320, so that the moisturizing drawer 300 is maintained stably, and the moisturizing drawer 300 is not directly blown with cold air, so that the temperature of the moisturizing drawer 300 is maintained stably, and the temperature and the humidity of the moisturizing drawer 300 are stable.

In addition, the cabinet 20 does not need an external water source to supplement water to the moisturizing drawer 300, and does not need energy-consuming components such as electric heating or a water mist generator, so that the moisturizing drawer 300 can keep high humidity. The moisturizing drawer 300 can be a fully-sealed bin, is not easily influenced by direct blowing of cold air during refrigeration, keeps stable humidity, and is more beneficial to the preservation of fruits and vegetables (the environment with stable temperature and humidity is beneficial to the preservation); the moisture-retaining film 320 can collect moisture in the drawer body 310, and redundant moisture can be stored in the moisture-retaining film 320, so that condensation cannot be formed due to the fact that the drawer body 310 forms a sealed bin, and fruits and vegetables are not easy to spoil due to the fact that the moisture-retaining drawer 300 does not contain condensed water.

It can be appreciated that the humidifying air duct 203 can guide the more humid air in the refrigerating space 202 to the humidifying membrane 320 under the action of the refrigerating fan 180, so that the humidifying membrane 320 can collect the more humid water from the humidifying air duct 203. In addition, the water molecules may move from a place where the humidity is high to a place where the humidity is low, so that the moisturizing film 320 may adjust the water molecules inside the drawer body 310, thereby allowing the moisturizing film 320 to adjust the humidity of the drawer body 310.

In some embodiments, the housing 200 may be provided with a freezing compartment (not shown), which may be provided at the bottom of the cabinet 20 and opposite to the refrigerating compartment 201, and the first refrigeration cycle circuit 101 of the refrigeration system 100 may be used to control the amount of cold air of the freezing compartment, helping to lower the temperature of the freezing compartment, so that the freezing compartment may freeze food.

Referring to fig. 4 and 5, the case 200 may include a housing 210, an outer contour of the housing 210 may be substantially rectangular or square, and the refrigerating compartment 201, the refrigerating space 202, the humidifying air duct 203, and the moisturizing drawer 300 may be located in the housing 210. The housing 210 has a protective function to protect various components disposed within the housing 210.

The housing 200 may further include a liner 220, where the liner 220 may be located within the housing 210, and where the liner 220 may be coupled to the housing 210 by screws or snaps, etc. The cabinet 220 may be formed with a refrigerating compartment 201, and the refrigerating compartment 201 may be used to cool food.

Referring to fig. 4 and 6, the case 200 may further include a duct board 230, the duct board 230 may be disposed in the case 210, the duct board 230 may be further connected to the case 210 by means of a buckle or a screw, etc., so that the duct board 230 and the case 210 form the refrigerating space 202,

the refrigerated space 202 may house a refrigerated evaporator 160. The second refrigeration cycle 102 of the refrigeration system 100 may control the amount of cold in the refrigerated space 202. When the second refrigeration cycle 102 of the refrigeration system 100 is in a refrigerated state, the refrigeration system 100 may generate cool air in the refrigerated space 202; when the refrigeration system 100 stops operating the second refrigeration cycle 102, the refrigeration system 100 is in a defrosting state, that is, the refrigeration evaporator 160 in the refrigeration system 100 needs to be defrosted, the refrigeration system 100 can generate more humid air in the refrigeration space 202, so that the air in the refrigeration space 202 is more humid, and the humidifying air duct 203 can guide the more humid air in the refrigeration space 202 to the humidifying membrane 320 under the action of the refrigeration fan 180, and the humidifying membrane 320 can absorb moisture in the humid air to adjust the humidity in the humidifying drawer 300.

In addition, the refrigerated compartment 201 and the refrigerated space 202 may be located on opposite sides of the air duct board 230, which facilitates the proper placement of the various components of the refrigeration appliance 10, thereby making the refrigeration appliance 10 more compact.

A humidifying air duct 203 may be formed between the air duct plate 230 and the case liner 220 in a surrounding manner, for example, a convex rib 240 may be disposed on a side of the air duct plate 230 facing the case liner 220, and the convex rib 240 may be abutted against a side of the case liner 220 facing the air duct plate 230; for another example, a side of the case container 220 facing the air duct plate 230 may be provided with a protruding rib 240, and the protruding rib 240 may be abutted against the side of the air duct plate 230 facing the case container 220, so that the air duct plate 230 and the case container 220 form the humidifying air duct 203, and the structure is simple and the cost is low. In addition, the specific shape of the ribs 240 may be designed according to the height and the extending direction of the humidification duct 203.

The air inlet 203a of the humidifying air duct 203 may be provided with a refrigerating fan 180, so that air in the refrigerating space 202 is guided to the humidifying air duct 203, thereby helping the humidifying air duct 203 guide air in the refrigerating space 202 to the humidifying membrane 320.

In some embodiments, the moisturizing film 320 can be located on top of the drawer body 310. In this way, the water molecules of the moisturizing film 320 sink under the action of gravity and gradually permeate into the drawer body 310, thereby facilitating the humidification of the fruits and vegetables stored in the drawer body 310. In addition, the fruits and vegetables stored in the drawer body 310 volatilize water upwards under the action of transpiration, and the moisturizing film 320 is arranged at the top of the drawer body 310 to facilitate absorption of water in the drawer body 310 (water molecules can move from a region with higher humidity to a region with lower humidity), so that the humidity in the drawer body 310 can be adjusted more effectively.

In some embodiments, the drawer body 310 may be provided with a receiving space 311 and a through hole (not shown), the through hole may be communicated with the receiving space 311, the moisturizing film 320 may be provided at the through hole, for example, the moisturizing film 320 may be located above the through hole; for another example, the moisture-preserving film 320 may be located at the through hole, so that water molecules of the moisture-preserving film 320 are conveniently introduced into the accommodating space 311 through the through hole, and the accommodating space 311 may accommodate fruits and vegetables, so as to improve user experience.

Referring to fig. 5 and 7, the moisturizing film 320 may include a water-absorbing layer 321 and a wind shielding layer 322 stacked, the wind shielding layer 322 may face the accommodating space 311, and the water-absorbing layer 321 may face away from the accommodating space 311.

The water-absorbing layer 321 may have various options, for example, the water-absorbing layer 321 may be a paper pulp water-absorbing layer; for another example, the water absorbing layer 321 may be a sponge water absorbing layer so that the water absorbing layer 321 may collect water molecules in the air.

The wind shielding layer 322 may be a polyethylene wind shielding layer, so that the wind shielding layer 322 can shield wind and allow water molecules to penetrate, and helps to avoid the humidifying air duct 203 from directly blowing to the accommodating space 311 of the drawer body 310.

The moisture-preserving film 320 may further include a protective layer 323, the protective layer 322 may be a non-woven protective layer, and the protective layer 323 is disposed above the water-absorbing layer 321, so as to reduce the risk of abrasion between the water-absorbing layer 321 and the air, and thus protect the water-absorbing layer 321.

The moisturizing film 320 is horizontally disposed on the drawer body 310. Thus, the water molecules of the moisturizing film 320 can be uniformly arranged on the moisturizing film 320, so that the water molecules are prevented from being gathered on any side of the moisturizing film 320, and the water molecules can be uniformly permeated into the drawer body 310 under the action of gravity, so that the humidifying effect of the moisturizing film 320 is effectively improved.

Referring to fig. 4 and 5, the cabinet 20 may further include an air guiding structure 400, for example, the air guiding structure 400 may be an air guiding strip 410; for another example, the air guiding structure 400 may be an air guiding plate. The air deflector may be connected to the cabinet 220 or the duct board 230 by means of screws or snap-in. The air guide structure 400 may be provided in the refrigerating compartment 201 between the moisturizing film 320 and the air outlet 203b of the humidification duct 203. In this way, the air guiding structure 400 can guide the moist air from the air outlet 203b of the humidifying air duct 203 to the surface of the moisturizing film 320, so that the moisturizing film 320 can collect the water molecules in the moist air.

The air guiding structure 400 includes a plurality of air guiding strips 410, the plurality of air guiding strips 410 are arranged at intervals, and the air guiding strips 410 extend from the moisture-preserving film 320 toward the air outlet 203b of the humidifying air duct 203. In this way, the air guiding strip 410 can make the moist air blown out from the air outlet 203b of the humidifying air duct 203 directly blow onto the moisturizing film 320 to collide with the air flow, so that the moisturizing film 320 is assisted to collect water molecules to the greatest extent.

In some embodiments, the spacing between the moisture-retaining film 320 and the air guiding structure 400 is L, wherein L is 10mm to 15mm in size. Specifically, the value of L may be, but is not limited to: 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm and 15mm. In this way, most of the air blown out from the air outlet 203b of the humidification duct 203 can effectively flow to the surface of the moisturizing film 320 through the air guide structure 400, and the air blown out from the air outlet 203b of the humidification duct 203 can be reduced from flowing out to the gap between the air guide structure 400 and the moisturizing film 320.

Referring to fig. 4 to 6, the cabinet 20 may further include a shelf plate 500, the shelf plate 500 may be provided in the refrigerating compartment 201, the shelf plate 500 may be connected to the cabinet 220 or the outer case 210 by means of screws or snaps, and the shelf plate 500 may help a user to place articles. The shelf plate 500 may be located above the moisturizing drawer 300.

A ventilation gap 204 may be formed between the shelf plate 500, the moisturizing drawer 300, and the case 200, the ventilation gap 204 may be communicated with the humidification duct 203, and the moisturizing film 320 may be located in the ventilation gap 204. The housing 200 may be provided with an air return opening 205, and the air return opening 205 may be in communication with the ventilation gap 204 and the refrigerated space 202. In this way, the humid air in the refrigerating space 202 can flow from the humidifying air duct 203 to the ventilation gap 204 under the action of the refrigerating fan 180, then flow from the ventilation gap 204 to the return air inlet 205, and finally flow from the return air inlet 205 to the refrigerating space 202, thereby forming a circulation loop of the humid air.

The cabinet 20 may further include a humidification damper 600, and the humidification damper 600 may be located in the humidification duct 203 to open or close the humidification duct 203. Thus, when the humidification damper 600 turns on the humidification duct 203, the second refrigeration cycle 102 stops operating, the refrigeration evaporator 160 is in a defrost state (stops operating), and the humidification duct 203 can guide the humidified air of the refrigeration space 202 to the humidification film 320 under the action of the refrigeration fan 180. In addition, the cabinet 20 may control the flow rate of the humidified air at the outlet 203b of the humidification duct 203 by controlling the opening of the humidification damper 600, thereby helping to precisely control the amount of air of the humidification duct 203 that guides the humidified air of the cooling space 202 to the humidification film 320.

In some embodiments, the housing 200 may also have a cooling air duct 206, and the cooling air duct 206 may be disposed between the duct plate 230 and the cabinet 220. For example, a side of the air duct plate 230 facing the case liner 220 may be provided with a rib 240, and the rib 240 may abut against the side of the case liner 220 facing the air duct plate 230; for another example, a side of the case container 220 facing the air duct plate 230 may be provided with a protruding rib 240, and the protruding rib 240 may be abutted against the side of the air duct plate 230 facing the case container 220, so that the air duct plate 230 and the case container 220 form the cooling air duct 206, and the structure is simple and the cost is low. In addition, the specific shape of the ribs 240 may be designed according to the height and the extending direction of the cooling air duct 206.

The cooling air duct 206 may be in communication with the cooling space 202 and the refrigerated compartment 201, and the cooling air duct 206 is located above the humidification air duct 203. In this way, the cooling air duct 206 is located above the humidifying air duct 203, and when the second refrigeration cycle 102 is operated, the cooling air duct 206 can quickly guide the cool air in the cooling space 202 to the refrigerating compartment 201, so that the cool air can be quickly settled in the refrigerating compartment 201.

The cabinet 20 may also include a refrigeration damper 700, and the refrigeration damper 700 may be positioned in the refrigeration channel 206 to open or close the refrigeration channel 206. In this way, when the cooling damper 700 is turned on the cooling air duct 206, the second cooling circulation loop 102 operates normally, the refrigeration evaporator 160 operates normally, and the cooling air duct 206 guides the cool air of the cooling space 202 to the refrigerating compartment 201 under the action of the refrigerating fan 180. In addition, the cabinet 20 may control the flow rate of the cold air flowing from the cooling air duct 206 to the refrigerating compartment 201 by controlling the opening degree of the cooling air door 700, thereby helping to precisely control the amount of the cold air flowing from the cooling air duct 206 to the refrigerating compartment 201.

It will be appreciated that the humidification duct 203 is provided with a humidification damper 600 and the refrigeration duct 206 is provided with a refrigeration damper 700 to facilitate the flow of cool air and humidified air in the refrigerated space 202 to the humidification duct 203 and the refrigeration duct 206, respectively. When the refrigeration system 100 is in the defrost state, moist air flows to the moisturizing film 320 through the humidifying damper 600, thereby humidifying the moisturizing drawer 300. And during humidification, having a separate humidification duct 203 is not affected by the cooling duct 206.

In some embodiments, the refrigerated compartment 201 may be in communication with the ventilation gap 204, such that air located in the refrigerated compartment 201 may be returned to the refrigerated space 202 through the return air inlet 205 to form a refrigerated air circulation loop.
