As shown in conjunction with fig. 1 to 7, an embodiment of the present disclosure provides a refrigerator including: a liner 10 and a drawer assembly. The side wall of the liner 10 is provided with a cooling air port 101 and a dehumidifying air port 104; the drawer assembly comprises a drawer cover plate 20, and a moisture permeable assembly 30 is arranged on the drawer cover plate 20; the cooling air port 101 is correspondingly arranged at the side part of the moisture permeable assembly 30, so that the blown air flow avoids the moisture permeable assembly 30; the dehumidifying air outlet 104 is disposed corresponding to the moisture permeable component 30, so that the blown air flows through the moisture permeable component 30 to take away the moisture penetrating from the moisture permeable component 30.

By adopting the refrigerator provided by the embodiment of the disclosure, the drawer is provided with a relatively closed space through the drawer cover plate 20, and the humidity in the drawer is regulated through the moisture permeable assembly 30, so that a relatively stable humidity environment is maintained in the drawer, namely, the aim of moisturizing is fulfilled; the dehumidifying air port 104 is arranged corresponding to the moisture permeable assembly 30, so that the blown air flows through the moisture permeable assembly 30 to take away the water vapor above the moisture permeable assembly 30, thereby increasing the humidity difference at two sides of the moisture permeable assembly 30, and accelerating the water vapor to permeate the moisture permeable assembly 30 to reduce the humidity in the drawer; the cooling air port 101 is correspondingly arranged at the side part of the moisture permeable assembly 30, so that blown air flow avoids the moisture permeable assembly 30, and the humidity balance at two sides of the moisture permeable assembly 30 is prevented from being damaged, thus, when the humidity in the drawer is higher than the humidity requirement, the air is simultaneously discharged through the cooling air port 101 and the dehumidifying air port 104, and the cooling and the dehumidifying are simultaneously carried out; when the humidity in the drawer meets or is lower than the humidity demand, only the cooling air port 101 is used for air outlet so as to avoid the humidity in the drawer from being reduced, so that a relatively stable humidity environment is kept in the drawer, and the demand of a user for moisturizing and preserving food stored in the freezing compartment or the temperature-changing compartment is met.

The side wall of the liner 10 is provided with an air supply channel, and the cooling air port 101 and the dehumidifying air port 104 are both communicated with the air supply channel. The air flow output by the air supply duct is blown out into the storage space defined by the liner 10 through the cooling air port 101 and the dehumidifying air port 104, and the refrigeration function is exerted. The air flows blown out from the cooling tuyere 101 and the dehumidifying tuyere 104 are the same in both humidity and temperature. The effect generated by the relative moisture permeable assembly 30 is different only for the different positions, so that the air port is functionally defined according to the purpose of the air port generated by the moisture permeable assembly 30, namely the cooling air port 101 and the dehumidifying air port 104.

The drawer component is placed in the storage space defined by the inner container 10, and is covered by the drawer cover plate 20, so that a relatively airtight space is formed inside the drawer, and air flows blown out of the cooling air port 101 and the dehumidifying air port 104 can be prevented from entering the drawer, and directly acts on the surface of food materials, so that serious water loss of the food materials is caused, and the edible taste and quality of the food materials are affected.

The drawer assembly comprising the drawer cover plate 20 can maintain food materials in the drawer in a high humidity environment, but the humidity exceeds a preset value, so that not only the taste and quality of the food materials in the drawer are affected, but also the freezing and refrigerating effects of the food materials are reduced. Therefore, the drawer cover plate 20 with the moisture permeable assembly 30 provided in this embodiment not only can realize the purpose of covering the drawer to form a closed space, but also can regulate the humidity of the environment in the drawer through the moisture permeable assembly 30, so as to ensure that the food in the drawer is in a humidity environment which can give consideration to both fresh-keeping and freezing effects.

The dehumidifying air port 104 is disposed corresponding to the moisture permeable component 30, and the air flow blown out from the dehumidifying air port 104 flows over the moisture permeable component 30 to blow away the moisture permeated from the moisture permeable component 30. In this way, the humidity difference exists between the inside humidity and the outside humidity of the moisture permeable assembly 30, so that the moisture in the drawer can continue and accelerate to be permeated out to the drawer, that is, the moisture in the drawer is accelerated to permeate the moisture permeable assembly 30 to the outside of the drawer, and the humidity in the drawer is reduced.

The cooling air port 101 is correspondingly arranged at the side part of the moisture permeable assembly 30, and the air flow blown out from the cooling air port 101 avoids the upper part of the moisture permeable assembly 30, i.e. the upper part of the moisture permeable assembly 30 is guaranteed to be windless as much as possible, thereby avoiding damaging the humidity balance at the two sides of the moisture permeable assembly 30. Thus, under the condition that the temperature of the cooling air outlet 101 is reduced, the humidity environment in the drawer can be kept stable.

When the humidity in the drawer is higher than the humidity demand, the air is discharged through the cooling air port 101 and the dehumidifying air port 104 at the same time, and the cooling and the dehumidifying are carried out at the same time; when the humidity in the drawer meets or is lower than the humidity demand, only the cooling air port 101 is used for air outlet so as to avoid the humidity in the drawer from being reduced, so that a relatively stable humidity environment is kept in the drawer, and the demand of a user for moisturizing and preserving food stored in the freezing compartment or the temperature-changing compartment is met.

The moisture permeable assembly 30 includes a moisture permeable film 50, and the moisture permeable film 50 has a three-layer structure of a hydrophobic layer, a water-conductive layer, and a hydrophilic layer, respectively. Wherein the hydrophobic layer faces into the drawer. The moisture permeability pore diameter of the moisture permeable membrane 50 is above a certain humidity threshold, and can be adjusted by itself according to the humidity value. Illustratively, the moisture permeability function starts when the humidity value is greater than 80% of the relative humidity, and the larger the humidity, the larger the moisture permeability aperture will be, the faster the moisture permeability rate, and when the humidity is less than 80% of the relative humidity, the moisture permeability aperture is locked, preventing the humidity from decreasing. The moisture permeable assembly 30 having the moisture permeable film 50 has an active moisture regulating function, and can ensure that the covered space of the moisture permeable film 50 has a specific humidity value. Thereby ensuring the fresh-keeping effect of the food materials with the humidity. In order to protect the moisture permeable film 50, non-woven fabrics are respectively added on two sides of the film, and plastic packaging is performed on the periphery, so that the moisture permeable film 50 is prevented from being damaged by external violence.

Alternatively, both the cooling tuyere 101 and the dehumidifying tuyere 104 are provided higher than the upper surface of the moisture permeable assembly 30.

In the case that the cooling air port 101 and the dehumidifying air port 104 are higher than the upper surface of the moisture permeable assembly 30, the air flow blown out by the cooling air port 101 and the dehumidifying air port 104 flows through the space above the drawer cover plate 20, so that on one hand, smooth circulation of the air flow is guaranteed, namely, the refrigerating air flow is blown to the storage space of the liner 10, so that the air flow circulates in the storage space, and the purpose of refrigeration is realized; on the other hand can blow away in time the steam that permeates out from the moisture permeability subassembly 30 through the air current that dehumidifies wind gap 104 blew off for the inside and outside humidity of moisture permeability subassembly 30 exists humidity difference, makes the steam in the drawer can continue and accelerate to permeate out to the drawer, accelerates the steam in the drawer promptly and permeates outside the moisture permeability subassembly 30 to the drawer, has so reduced the humidity in the drawer.

Optionally, the moisture permeable assembly 30 is located at the middle region of the drawer cover 20, and the length direction of the moisture permeable assembly 30 is consistent with the air flow direction passing through.

The moisture permeable assembly 30 is located in the middle region of the drawer cover 20, so that the moisture in the drawer flows to the middle region, which helps to ensure that the humidity conditions around the drawer are consistent, and avoid excessive local humidity and excessive local dryness.

In addition, the moisture permeable assembly 30 is disposed in the middle area of the drawer cover 20, that is, the drawer cover 20 is symmetrically disposed, so that the overall structural strength of the drawer cover 20 and the stability in the use process can be ensured.

The length direction of the moisture permeable assembly 30 is consistent with the flowing air flow direction, which can be understood that the moisture permeable assembly 30 is arranged along the air flow direction, a certain area is reserved for the air flow blown out from the cooling air port 101, the air flow blown out from the cooling air port 101 is prevented from flowing through the moisture permeable assembly 30, the humidity balance inside and outside the moisture permeable assembly 30 is damaged, and the stability of the humidity environment in the drawer is further affected.

Alternatively, the cooling tuyere 101 includes a first tuyere 102 and a second tuyere 103, and the first tuyere 102 and the second tuyere 103 are respectively disposed at two sides of the moisture permeable assembly 30.

The cooling tuyere 101 has a function of blowing out an air flow and cooling and refrigerating the whole chamber. Especially, when the drawer cover plate 20 is covered on the top of the drawer, the air flow cannot directly contact with food materials in the drawer, and the air flow and the food materials cool and refrigerate through indirect heat exchange, so that the cooling rate of the food materials is slower.

Through setting up first wind gap 102 and second wind gap 103, can increase the air current flow that blows out, the air current that blows out from first wind gap 102 and second wind gap 103 flows through the regional remaining drawer apron 20 of non-moisture permeability subassembly 30, can help accelerating the heat transfer rate between air current and drawer apron 20 and the drawer to accelerate the rate of indirect heat transfer between air current and the food material, and then promote the refrigerating rate of food material.

In addition, the first air port 102 and the second air port 103 are respectively disposed on two sides of the moisture permeable assembly 30, so that pressure balance on two sides of the moisture permeable assembly 30 is facilitated under the condition that the air flows are blown out from the first air port 102 and the second air port 103, the air flows are further prevented from flowing above the moisture permeable assembly 30, and the purpose that the air flows blown out from the cooling air port 101 are avoided from the moisture permeable assembly 30 is achieved.

Optionally, the dehumidifying tuyere 104 is located between the first tuyere 102 and the second tuyere 103.

The dehumidifying tuyere 104 is located between the first tuyere 102 and the second tuyere 103, and it is understood that the dehumidifying tuyere 104, the first tuyere 102 and the second tuyere 103 are disposed on the same side. In this way, under the condition that the dehumidifying air port 104, the first air port 102 and the second air port 103 blow air simultaneously, the air flows blown out by the three air ports have the same flow direction, so that smooth flow of the air flows is facilitated, air flow disturbance is avoided, and stability of the refrigerator in the use process is facilitated to be ensured.

It should be noted that, the dehumidifying air port 104 is located between the first air port 102 and the second air port 103, especially located at the middle position of the first air port 102 and the second air port 103, which is helpful for ensuring the air pressure balance above the drawer cover 20, i.e. ensuring the stability of the air flow under the condition that the three air ports are opened together for blowing.

Optionally, the drawer assembly further comprises: a drawer body 70 having a storage cavity; the humidity sensor 80 is disposed on the drawer body 70 for detecting the humidity in the storage cavity.

The drawer body 70 has a storage cavity in which food material is stored. The opening of the drawer body 70 is located at the top, and the drawer cover 20 is disposed on the top of the drawer body 70 to close the opening of the drawer body 70 at the top.

The humidity sensor 80 is disposed on a side wall of the drawer body 70, and it is understood that the humidity sensor 80 is embedded on the side wall of the drawer body 70 to detect the humidity in the storage cavity. Thus, the data detected by the humidity sensor 80 is helpful for users to know the humidity condition in the drawer in time on one hand, and can be associated with other components on the other hand, so that the humidity condition in the drawer can be automatically controlled and regulated, the requirements of the users are met, and the use experience of the users is improved based on automatic control.

In practical applications, the humidity sensor 80 is not located on the flow path of the air flow blown out from the cooling air port 101 and the dehumidifying air port 104, so that detection errors caused by the air flow continuously acting on the humidity sensor 80 can be avoided.

Optionally, the cooling air port 101 is provided with a first air door, the first air door is connected with the humidity sensor 80, and the first air door triggers an action according to a signal transmitted by the humidity sensor 80 to open or close the cooling air port 101.

The cooling air port 101 is provided with a first air door, and the opening and closing of the cooling air port 101 can be controlled through the first air door. Under the condition that the first air door is connected with the humidity sensor 80, according to the signal transmitted by the humidity sensor 80, namely under the condition that the detected humidity in the drawer is lower than the minimum humidity threshold value, the first air door is triggered to act, and the cooling air port 101 is closed, so that the continuous reduction of the temperature in the storage space of the liner 10 can be avoided, and the continuous reduction of the humidity can be avoided. It should be noted that the minimum humidity threshold may be the minimum humidity requirement required in the room.

In general, the cooling air inlet 101 is not frequently opened and closed due to humidity fluctuation detected by the humidity sensor 80, so that the cooling requirement of other drawers in the compartment or stored food materials is not affected. I.e. it can be understood that the cooling tuyere 101 is normally opened. Only when the cooling temperature is adjusted, the opening and closing of the cooling tuyere 101 is adjusted.

Optionally, the dehumidifying tuyere 104 is provided with a second air door, and the second air door is connected with the humidity sensor 80, and the second air door triggers an action according to a signal transmitted by the humidity sensor 80 so as to open or close the dehumidifying tuyere 104.

The dehumidifying tuyere 104 is provided with a second damper, by which opening and closing of the dehumidifying tuyere 104 can be controlled. When the second damper is connected to the humidity sensor 80, the second damper is triggered to operate to close the dehumidifying air outlet 104 in response to a signal transmitted from the humidity sensor 80, that is, when it is detected that the humidity in the drawer is lower than the first humidity threshold. Therefore, the continuous reduction of the humidity in the drawer can be avoided, and the moisture preservation and fresh keeping requirements of food materials are influenced. When the humidity in the drawer is detected to be higher than the second humidity threshold value, the second air door is triggered to act, and the dehumidifying air port 104 is opened. Like this, through the air current that dehumidifies wind gap 104 blowout, take away from the steam that permeates out of the moisture permeability subassembly 30, increase the humidity difference of the inside and outside both sides of moisture permeability subassembly 30, accelerate the steam in the drawer and permeate through wet film 50, reduce the humidity in the drawer, satisfy the food material to the requirement of fresh-keeping humidity.

Optionally, the drawer cover 20 is configured with a hollowed-out area, and the moisture permeable assembly 30 includes: the moisture permeable film 50 is embedded in the hollowed-out area of the drawer cover plate 20, so that when the drawer cover plate 20 is covered on the opening of the drawer body 70, the moisture in the drawer body 70 is permeated out through the moisture permeable film 50, and the humidity in the drawer body 70 is regulated.

The moisture permeable film 50 is embedded in the hollow area of the drawer cover 20, and the moisture permeable film 50 can only transmit water vapor and cannot transmit air. In this way, when the drawer cover 20 is covered on the opening of the drawer body 70, the water vapor in the drawer is transmitted out of the drawer through the moisture-transmitting film 50, so as to achieve the purpose of adjusting the humidity in the drawer body 70, and the humidity in the drawer meets the requirement.

The moisture permeability pore diameter of the moisture permeable membrane 50 is above a certain humidity threshold, and can be adjusted by itself according to the humidity value. Illustratively, the moisture permeability function starts when the humidity value is greater than 80% of the relative humidity, and the larger the humidity, the larger the moisture permeability aperture will be, the faster the moisture permeability rate, and when the humidity is less than 80% of the relative humidity, the moisture permeability aperture is locked, preventing the humidity from decreasing. The moisture permeable assembly 30 having the moisture permeable film 50 has an active moisture regulating function, and can ensure that the covered space of the moisture permeable film 50 has a specific humidity value. Thereby ensuring the fresh-keeping effect of the food materials with the humidity.

Illustratively, as shown in connection with fig. 5-7, the moisture permeable assembly 30 further includes a lower seat 40 and a moisture permeable membrane 50. The lower seat 40 is provided with a first hollowed-out part 401 for covering the top of the drawer; the moisture permeable film 50 is arranged above the lower seat 40; wherein, the inside wall of the first hollow portion 401 is configured with an upwardly inclined water vapor guiding surface 402 and a downwardly inclined condensed water guiding surface 403, and the condensed water guiding surface 403 is located above the water vapor guiding surface 402 and is disposed in an intersecting manner. In this way, the moisture permeable assembly 30 is located at the top of the drawer, and the moisture in the drawer moves to the moisture permeable membrane 50 through the first hollowed-out portion 401 of the lower seat 40, so that the purpose of moisture permeability, namely moisture regulation, is achieved through the moisture permeable membrane 50; through the steam guide surface 402 and the condensed water guide surface 403 of the first hollowed-out portion 401, not only the fluidity of steam can be increased, but also the condensed water formed by condensation inside the moisture permeable membrane 50 can be guided, so that the steam and the condensed water are prevented from being frozen inside the lower seat 40 and the moisture permeable membrane 50, and the frosting quantity can be effectively reduced.

In the case that the lower seat 40 is horizontally placed, the inner sidewall of the first hollowed-out portion 401 protrudes outwards and has a triangular or triangular-like cross section. As can be understood, the condensed water guide surface 403 and the water vapor guide surface 402 are two intersecting planes in which the inner side wall of the first hollowed-out portion 401 protrudes outward. Wherein the condensate water guide surface 403 is located above the water vapor guide surface 402.

Under the condition that the drawer cover plate 20 with the moisture permeable assembly 30 is covered on the drawer body 70, water vapor in the drawer body 70 flows upwards along the water vapor guide surface 402, in the flowing process, water drops carried in the water vapor are condensed into condensed water after contacting the water vapor guide surface 402, then slide downwards along the obliquely arranged water vapor guide surface 402, and drop into the drawer body 70, so that the water vapor in the drawer can be reduced from being discharged, and the water vapor can be prevented from being frosted on the side wall of the first hollowed-out part 401, so that the blockage is caused, and the flow of the water vapor is influenced.

Because the drawer cover 20 plays a role of indirectly cooling food materials in the drawer, the outside air of the drawer is lower than the temperature in the drawer, so when the vapor in the drawer is higher than the set humidity and is emitted through the moisture permeable assembly 30, the vapor contacted with the lower cover is condensed, that is, the vapor is condensed on the condensed water guide surface 403 of the first hollowed-out part 401, so as to form condensed water. Based on the inclined arrangement of the condensate water guide surface 403, the condensate water flows down the inclined surface, thereby avoiding condensation and freezing on the condensate water guide surface 403. In addition, the condensed water guiding surface 403 faces the moisture permeable membrane 50, so that not only can steam flow along the condensed water guiding surface 403 to guide condensed water, but also the contact area between the steam on the first hollowed-out portion 401 and the moisture permeable membrane 50 can be increased.

Optionally, a water stop step 404 is configured at the intersection of the water vapor guiding surface 402 and the condensed water guiding surface 403, and the water stop step 404 is used for stopping water drops carried in water vapor moving to the water stop step 404 along the water vapor guiding surface 402 from continuing to move upwards; wherein, both ends of the water stop step 404 are respectively connected with the top of the water vapor guide surface 402 and the bottom of the condensed water guide surface 403.

The water stop step 404 is located at the intersection of the water vapor guiding surface 402 and the condensed water guiding surface 403, and the bottom of the condensed water guiding surface 403 protrudes from the top of the water vapor guiding surface 402. When the water vapor in the drawer moves upwards to the water stop step 404 along the water vapor guide surface 402, water drops carried in part of the water vapor are attached to the water vapor guide surface 402, and under the guide of the inclined arrangement of the water vapor guide surface 402, the water drops attached to the water vapor guide surface 402 move downwards to drop. And the water drops carried in the other part of the water vapor move to the water stop step 404, adhere to the surface of the water stop step 404 under the stop action of the water stop step 404, and then drop into the drawer. It should be noted that, the water stop step 404 not only can be used to stop the water drop in the vapor, but also can play a certain role in blocking the upward movement of the vapor, and can further prolong the time that the vapor is located in the drawer. Also, the water droplets in the water vapor include not only water droplets originally carried but also water droplets formed by condensation of the water vapor during movement.
