Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and more specifically, to a refrigerator and a control method of the refrigerator. Background Art

[0002] With the rapid development of user demand and market, in related technologies, refrigerators have an air curtain function. When the refrigerator door is opened, the fan drives the cold air to form a three-dimensional air curtain to isolate the cold air on the side of the compartment close to the door, thereby preventing the exchange of cold and heat between the inside and outside of the compartment, reducing the loss of cold air when the user opens the refrigerator door, and reducing the temperature fluctuation of the compartment.

[0003] In addition, since the air-cooled refrigerator will quickly take away the humid air in the refrigerator during the air supply process, the flow of wind will also accelerate the transpiration of plants, which is not conducive to the preservation of fruits and vegetables stored in the compartment. Therefore, the refrigerator also has a humidification function, that is, a water box is provided on the refrigerator, and liquid is stored in the humidification water box. The fan drives the cold air to flow and pass through the water box, so that the cold air carries part of the liquid to flow to the compartment, thereby increasing the humidity inside the compartment.

[0004] However, the temperature and humidity control of the related art intermediate chamber is inconvenient. Summary of the invention

[0005] Based on this, the present application provides a refrigerator and a control method for the refrigerator. The refrigerator is equipped with a fan to provide airflow for the humidification air duct, the wind curtain air duct and the refrigeration air duct at the same time to simplify the structural design of the refrigerator, and the on-off state of the humidification air duct is controlled by setting a first air door, and the on-off state of the refrigeration air duct is controlled by setting a second air door, so as to control the temperature and humidity of the storage room respectively as needed, for convenient control.

[0006] In a first aspect, the present application provides a refrigerator, comprising:

[0007] The box body has a storage room, an air duct for air flow, an air curtain outlet and a refrigeration outlet, the air duct includes a humidification air duct, an air curtain air duct and a refrigeration air duct, the humidification air duct and the air curtain air duct are both connected to the air curtain outlet, the refrigeration air duct is connected to the refrigeration outlet, the air curtain outlet and the refrigeration outlet are both connected to the storage room, and the air outlet direction of the air curtain outlet is along the height direction of the storage room;

[0008] A fan is connected to the air duct and is configured to generate an air flow;

[0009] A water box, the water box is configured to store humidification liquid, and the water box is disposed in the humidification air duct;

[0010] A first damper that can be opened and closed, the first damper is located in the humidification air duct and between the air inlet of the air duct and the water box, and the first damper is configured to control the on and off state of the humidification air duct;

[0011] The second air door can be opened and closed. The second air door is located in the refrigeration air duct and is configured to control the on-off state of the refrigeration air duct.

[0012] The refrigerator of the present application forms a storage room for storing items by arranging a box body, and forms an air duct on the box wall of the box body, arranges a fan to disturb the flow of cold air to form an airflow, and drives the airflow into the storage room, arranges a water box to store humidifying liquid, arranges a humidifying air duct and arranges the water box in the humidifying air duct so that the airflow carries the humidifying liquid while flowing, arranges an air curtain air duct for the airflow to flow and form a three-dimensional air curtain, arranges an air curtain outlet for the airflow of the humidifying air duct and the air curtain air curtain duct to enter the storage room, and arranges a refrigeration air duct and a refrigeration air outlet for the airflow to flow and enter the storage room to carry out wind For cooling, a first air door is provided in the humidifying air duct between the water box and the air inlet of the air duct, and the on-off state of the humidifying air duct between the water box and the air inlet of the air duct is controlled by opening and closing the first air door, so as to adjust the temperature according to the humidity in the storage room; a second air door is provided in the refrigerating air duct, and the on-off state of the refrigerating air duct is controlled by opening and closing the second air door, so as to adjust the temperature according to the storage room. In this way, the wind curtain function, humidification function and air cooling function of the refrigerator can be driven by setting up one fan, thereby simplifying the structure of the refrigerator, and the humidification function and air cooling function can be independently regulated, and the control of the refrigerator is more convenient.

[0013] In some embodiments of the present application, the water box has a water box air inlet and a water box air outlet arranged in sequence along the flow direction of the air flow in the humidification air duct, and the water box air inlet and the water box air outlet are respectively located on opposite sides of the water box, and the first air gate is located between the air inlet of the air duct and the water box air inlet.

[0014] With such arrangement, the airflow can pass through the air inlet and the air outlet of the water box, and then the airflow carries part of the humidification liquid into the storage chamber, thereby increasing the humidity in the storage chamber. Since the air inlet and the air outlet of the water box are respectively located on opposite sides of the water box, and along the flow direction of the airflow of the humidification air duct, the airflow can go straight in and out of the water box, which can not only reduce the flow resistance of the airflow, but also help to simplify the structural design of the water box. The first air door is arranged between the air inlet of the air duct and the air inlet of the water box, and the first air door is closed to cut off the path of the airflow entering the air inlet of the water box, and the airflow cannot enter the inside of the water box.

[0015] In some embodiments of the present application, the first damper is rotatably connected to the humidification air duct; and / or, the second damper is rotatably connected to the refrigeration air duct.

[0016] With such arrangement, the first air door can be rotated relative to the humidification air duct to be in an open state or a closed state, thereby controlling the on-off state of the humidification air duct. The second air door can be rotated relative to the refrigeration air duct to control the open and closed state of the second air door, thereby controlling the on-off state of the humidification air duct.

[0017] In some embodiments of the present application, the water box includes a box body, and the box body has an inner cavity;

[0018] A partition, the partition is configured to separate the inner cavity into a water holding cavity and a ventilation cavity, the water box air inlet and the water box air outlet are located on opposite sides of the ventilation cavity, and the partition has an avoidance opening;

[0019] And a water absorbing component is located in the ventilation cavity and extends into the water containing cavity through the avoidance opening.

[0020] With such arrangement, the water-absorbing member can be extended into the water-containing cavity to absorb the humidified liquid. When the air flow enters the ventilation cavity through the air inlet of the water box, the air flow blows through the water-absorbing member and takes away some of the moisture on the water-absorbing member, and then flows out of the ventilation cavity through the air outlet of the water box, and finally enters the storage room through the air outlet of the wind curtain.

[0021] In some embodiments of the present application, the fan is connected to the side wall of the box, the refrigeration air duct is located on the side wall of the box, and the humidification air duct and the air curtain air duct extend from the side wall of the box to the top wall of the box.

[0022] In this arrangement, since the evaporator 700 is arranged on the side wall of the box and is located below the fan, arranging the refrigerated air duct on the side wall of the box can shorten the flow path of the refrigerated air duct to reduce the loss of cold air during air flow, and arranging the refrigerated air outlet on the rear side wall of the box can make the refrigerated air duct discharge air from the rear side of the storage room and then blow it evenly to the front side of the storage room, which can achieve a better air cooling effect in the storage room.

[0023] In some embodiments of the present application, the side wall of the box body has a first flow cavity, the top wall of the box body has a second flow cavity and two third flow cavities, the two third flow cavities are located on opposite sides of the second flow cavity along the thickness direction of the box body, the first flow cavity and the second flow cavity together form a humidification air duct, and the first flow cavity and the third flow cavity together form an air curtain air duct.

[0024] Such an arrangement can make the parts of the humidification duct and the wind curtain duct on the side wall of the box body connected to each other, while the parts of the humidification duct and the wind curtain duct on the top wall of the box body are isolated from each other. The fan drives the airflow to flow along the first flow cavity, and when it flows to the junction of the side wall of the box body and the top wall of the box body, it begins to diverge, and then the airflow flows along the second flow cavity and the third flow cavity to the wind curtain outlet respectively, thereby simplifying the air duct structure design of the side wall of the box body.

[0025] In some embodiments of the present application, the refrigeration air duct includes a first refrigeration air duct and a second refrigeration air duct, and the airflows of the first refrigeration air duct and the second refrigeration air duct have opposite flow directions.

[0026] With this arrangement, air can enter the storage room from refrigerated air outlets at different locations, thereby evenly cooling the storage room.

[0027] In a second aspect, the present application provides a refrigerator control method, which is applied to the refrigerator provided in the first aspect, and the method includes:

[0028] Determine the temperature and humidity values ​​inside the storage compartment of the refrigerator;

[0029] If the humidity value is lower than the preset humidity threshold, the first damper is controlled to open;

[0030] If the temperature value is higher than the preset temperature threshold, the second air door is controlled to open.

[0031] In this way, the opening and closing control of the first damper and the second damper can be realized through the above control method, thereby conveniently realizing the temperature control and humidity control of the refrigerator.

[0032] In some embodiments of the present application, the present application provides a method for controlling a refrigerator, and if the humidity value is lower than a preset humidity threshold, controlling the first air door to open, specifically includes:

[0033] Determine the open and closed status of the refrigerator door;

[0034] If the door body is in a closed state and the humidity value is lower than a preset humidity threshold, the first air door is controlled to open.

[0035] In this way, the above control method determines the open and closed state of the door body, and then confirms whether there is a user standing in front of the storage room, so as to avoid moisture in the airflow sticking to the user when the door body is opened, affecting the user experience.

[0036] In a third aspect, the present application provides a refrigerator, comprising:

[0037] The box body has a storage room, an air duct for air flow and an air curtain outlet, the air duct is connected to the storage room, the air duct includes a humidification air duct, an air curtain air duct and a refrigeration air duct, and the humidification air duct and the air curtain air duct are both connected to the air curtain outlet;

[0040] A first damper, the first damper is configured to control the on / off state of the humidification air passage;

[0041] The second damper is configured to control the on / off state of the refrigeration air duct.

[0042] The refrigerator of the present application provides airflow for the humidification air duct, the air curtain air duct and the refrigeration air duct by setting a fan, and then provides power for the humidification, air curtain and air cooling of the refrigerator by one fan.

The second air door is set in the refrigeration air duct to control the on-off state of the refrigeration air duct by controlling the opening and closing state of the second air door, thereby adjusting the temperature in the storage room. The first air door and the second air door are independently controlled. Therefore, the temperature and humidity of the refrigerator are more convenient to control. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] In the related art, the refrigerator has air cooling function, air curtain function and humidification function. The air cooling function mainly relies on the cold air circulation in the compartment of the refrigerator to reduce the temperature inside the compartment. When the refrigerator starts to operate, the motor drives the compressor to start working, sucking in the refrigerant in the low pressure and normal temperature state, and compressing it into a high temperature and high pressure gas. These refrigerants in the high temperature and high pressure state are sent to the condenser after leaving the compressor. Since the temperature of the refrigerant entering the condenser is higher than the room temperature, the heat is dissipated outward through the condenser, so that the temperature of the refrigerant is reduced and condensed from gas to liquid, and then the refrigerant leaves the condenser and flows to the evaporator. The pressure of the refrigerant drops suddenly in the evaporator. Due to the sharp drop in pressure in the evaporator, the refrigerant evaporates violently, from liquid to gas, and the temperature drops during this process. Therefore, the evaporator can cool the surrounding air to form cold air. If it is necessary to allow a large amount of cold air to enter the interior of the compartment to quickly reduce the temperature inside the compartment, a fan is also required to be arranged on the periphery of the condenser, and the cold air is driven by the fan to flow into the interior of the compartment. Since heat always transfers from a higher temperature to a lower temperature, the higher temperature items in the room exchange heat with the cold air, thus achieving the purpose of air cooling. After the above process is completed, the refrigerant medium re-enters the compressor, thus starting the next cycle.

[0065] Since the door of the refrigerator needs to be opened frequently to take out the items placed inside the compartment, but opening the door will make the inside of the compartment and the outside of the compartment connected, since heat is always transferred from a higher temperature place to a lower temperature place, the cold air inside the compartment will flow out to the outside of the compartment, thereby increasing the temperature inside the compartment and reducing the refrigeration effect of the refrigerator. Therefore, an air curtain can be set on the front side of the compartment. When the door of the refrigerator is opened, the fan drives the cold air to form a three-dimensional air curtain that isolates the cold on the side of the compartment close to the door, thereby preventing the cold and heat exchange between the inside and the outside of the compartment, reducing the cold loss during the user's use of the refrigerator with the door open, and reducing the temperature fluctuation of the compartment.

[0066] In addition, since the air-cooled refrigerator will quickly take away the humid air in the refrigerator during the air supply process, the flow of air will also accelerate the transpiration of plants, which is not conducive to the preservation of fruits and vegetables stored in the compartment. Therefore, the refrigerator also has a humidification function, that is, a water box is set on the refrigerator, and liquid is stored in the humidification water box. The fan drives the cold air to flow and pass through the water box, so that the cold air carries part of the liquid to the compartment, thereby increasing the humidity inside the compartment.

[0067] However, the temperature and humidity control of the intermediate chamber in the related technology is less convenient. The inventors have found that this is because if independent control of temperature and humidity is to be achieved, the refrigerator needs to be equipped with a fan to drive cold air to form a three-dimensional wind curtain, and a wet fan to drive cold air through the water box, and even a fan to drive cold air into the compartment. Therefore, the refrigerator needs to be equipped with two to three fans, and the opening and closing of each corresponding fan is controlled to control whether to form a wind curtain, whether to humidify the compartment, and whether to air-cool the compartment. This not only increases the complexity of the structural design, but also increases the processing cost of the refrigerator.

[0068] And if the number of fans is simplified, for example, one fan is used to drive cold air for air cooling, form an air curtain and humidify the compartment at the same time, then the temperature and humidity must be controlled at the same time, that is, when the fan is turned on, the cold air will form a three-dimensional air curtain in front of the compartment at the same time, and humidify the compartment and air-cool the compartment at the same time. When the fan is turned off, the air curtain function, the humidification function and the air cooling function will all be turned off, so the independent control of temperature and humidity cannot be achieved, and the control of the refrigerator is less convenient.

[0069] In order to solve the above technical problems, the refrigerator in the embodiment of the present application is provided with a fan to provide airflow for the humidification air duct, the wind curtain air duct and the refrigeration air duct at the same time, so as to simplify the number of fans and further simplify the structural design of the refrigerator, and control the on-off state of the humidification air duct by setting a first air door, and control the on-off state of the refrigeration air duct by setting a second air door, so as to respectively adjust the temperature and humidity of the storage chamber as needed, thereby facilitating the control of the temperature and humidity of the refrigerator.

[0070] Figure 1 A schematic diagram of the structure of a refrigerator provided in an embodiment of the present application; Figure 2 for Figure 1 Refer to the top view of Figure 1 and Figure 2 As shown, an embodiment of the present application provides a refrigerator, which includes: a box body 100, the box body 100 has a storage chamber (not shown in the figure), an air duct 110 for air circulation, an air curtain outlet 120 and a refrigeration outlet 130, the air duct 110 includes a humidification air duct 111, an air curtain air duct 112 and a refrigeration air duct 113, the humidification air duct 111 and the air curtain air duct 112 are both connected to the air curtain outlet 120, the refrigeration air duct 113 is connected to the refrigeration air outlet 130, the air curtain outlet 120 and the refrigeration air outlet 130 are both connected to the storage chamber, and the air outlet direction of the air curtain outlet 120 is along the height direction of the storage chamber.

[0071] The fan 200 is connected to the air duct 110 , wherein the fan 200 is configured to generate airflow.

[0072] The water box 300 is configured to store humidification liquid, and the water box 300 is disposed in the humidification air duct 111. The water box 300 can be connected to the housing 100 in a detachable manner, for example, the water box 300 can be connected to the housing 100 in a snap-fit ​​manner, so that the water box 300 can be removed from the housing 100 to replenish the humidification liquid.

[0073] The first damper 400 can be opened and closed. The first damper 400 is located in the humidification air duct 111 and between the air inlet of the air duct 110 and the water box 300 . The first damper 400 is configured to control the on-off state of the humidification air duct 111 .

[0074] The second damper 500 can be opened and closed. The second damper 500 is located in the refrigeration air duct 113 and is configured to control the on / off state of the refrigeration air duct 113. The second damper 500 can be disposed at one end of the refrigeration air duct 113 near the refrigeration air outlet 130.

[0075] It is understandable that the refrigerator provided in the embodiment of the present application may further include at least two door bodies 600, the box body 100 may have at least two storage chambers, one for refrigeration and preservation, and the other for freezing and preservation, and the door body 600 may be rotatably connected to the box body 100 to open or close the storage chamber. The two door bodies 600 may be spaced apart along the height direction of the refrigerator, or may also be spaced apart along the width direction of the refrigerator.

[0076] In the related art, if the humidity and temperature of the storage room need to be regulated separately, multiple fans 200 need to be provided. In the embodiment of the present application, the fan 200 is connected to the box body 100. The box wall of the box body 100 is provided with a humidification air duct 111, an air curtain air duct 112 and a refrigeration air duct 113. The humidification air duct 111, the air curtain air duct 112 and the refrigeration air duct 113 share the same fan 200. That is to say, when the fan 200 is working, the blades of the fan 200 disturb the cold air around the evaporator 700 to form multiple airflows, and flow along the humidification air duct 111, the air curtain air duct 112 and the refrigeration air duct 113 respectively. This not only simplifies the number of fans 200, but also simplifies the structure of the refrigerator and reduces the cost of the refrigerator.

[0077] in, Figure 1 The flow route of the airflow is shown in the figure, and the flow direction of the airflow can be referred to as shown by the dotted arrow. The humidification air duct 111, the wind curtain air duct 112 and the refrigeration air duct 113 can take in air together through the air inlet of the air duct 110, and the humidification air duct 111 and the wind curtain air duct 112 can discharge air together through the wind curtain air outlet 120, and the refrigeration air duct 113 can discharge air through the refrigeration air outlet 130. The water box 300 can directly use the fan 200 that forms the wind curtain to realize the flow of water mist, without the need to carry the fan 200 separately, which can simplify the structure of the box body 100 to a certain extent and save costs.

[0078] When the air flow flows through the wind curtain duct 112 to the wind curtain outlet 120, the air flow forms a three-dimensional wind curtain on the side of the storage room close to the door body 600, so as to isolate the inside of the storage room and the outside of the storage room through the wind curtain. When the door body 600 is opened, the heat exchange between the inside of the storage room and the outside of the storage room can be isolated, thereby reducing the temperature fluctuation of the storage room.

[0079] When the air flow flows through the humidification air duct 111 to the wind curtain outlet 120, since the water box 300 is set in the humidification air duct 111, the air flow needs to flow from one side of the water box 300 to the other side of the water box 300, and take away the humidification liquid stored in the water box 300, and then enter the storage room from the wind curtain outlet 120. In this way, when the air flow flowing through the humidification air duct 111 enters the storage room through the wind curtain outlet 120, the front side of the storage room close to the door body 600 can not only form a three-dimensional wind curtain, but also increase the humidity inside the storage room.

[0080] When the air flows through the refrigeration air duct 113 to the refrigeration air outlet 130, the storage room can be cooled by air so that the temperature inside the storage room is maintained at a preset temperature threshold. There can be multiple refrigeration air ducts 113 and refrigeration air outlets 130, and the multiple refrigeration air outlets 130 are dispersedly arranged at various positions of the box body 100, so that the air flow is evenly dispersed to various parts of the storage room through the multiple refrigeration air outlets 130, so as to evenly reduce the temperature of various parts of the storage room.

[0081] In order to achieve independent control of the humidity of the storage room, a first damper 400 that can be opened and closed is provided in the humidification air duct 111. For example, the first damper 400 is movably connected to the humidification air duct 111, or the first damper 400 is rotatably connected to the humidification air duct 111. In this way, when the humidity in the storage room is low and humidification is required, the first damper 400 is opened to keep the humidification air duct 111 unobstructed, and the air flow can flow from the water box 300 and take away a certain amount of moisture, and finally enter the storage room through the air curtain outlet 120. When the humidity in the storage room is high and humidification is not required, the first damper 400 is closed to cut off the flow of the humidification air duct 111, and the air flow from the fan 200 can enter the storage room from the air curtain outlet 120 along the air curtain air duct 112, and enter the storage room from the refrigeration air outlet 130 along the refrigeration air duct 113, thereby forming a three-dimensional air curtain and cooling the storage room.

[0082] In order to achieve independent control of the temperature of the storage room, a second damper 500 that can be opened and closed is provided in the refrigeration air duct 113. For example, the second damper 500 is movably connected to the refrigeration air duct 113, or the second damper 500 is rotatably connected to the refrigeration air duct 113. In this way, when the temperature in the storage room is high and needs to be cooled down, the second damper 500 is opened to keep the refrigeration air duct 113 unobstructed, and multiple air flows can flow along each refrigeration air duct 113 and enter the storage room through the refrigeration air outlets 130 dispersed in various places, so as to quickly reduce the temperature in the storage room. When the temperature in the storage room is low and does not need to be cooled down, the second damper 500 is closed to keep the refrigeration air duct 113 in a cut-off state, and the air flow from the fan 200 can flow along the air curtain air duct 112 and the humidification air duct 111, and finally enter the storage room from the air curtain air outlet 120, thereby forming a three-dimensional air curtain at the front side of the storage room and humidifying the storage room.

[0083] It should be noted that the humidity and temperature of the refrigerator can also be controlled at the same time. Exemplarily, when the temperature in the storage room is high and the humidity in the storage room is low, the first damper 400 and the second damper 500 can be opened, so that the airflow from the fan 200 can flow along the wind curtain duct 112, the humidification duct 111 and the refrigeration duct 113 respectively, so as to cool the storage room, form a three-dimensional wind curtain at the front side of the storage room, and humidify the storage room at the same time. Alternatively, when the temperature in the storage room is low and the humidity in the storage room is high, the first damper 400 and the second damper 500 can be closed, so that the airflow from the fan 200 can only flow along the wind curtain duct 112 and flow out from the wind curtain outlet 120 to form a three-dimensional wind curtain at the front side of the storage room.

[0084] In some embodiments, the first damper 400 can be set at any position in the humidification air duct 111, as long as the on-off state of the humidification air duct 111 can be controlled. In order to achieve a better control effect, the first damper 400 is set in the humidification air duct 111 between the water box 300 and the air inlet of the air duct 110. In this way, when the first damper 400 is in a closed state, the humidification air duct 111 leading to the water box 300 is cut off, the airflow cannot continue to flow, and the airflow cannot take away the moisture in the water box 300. If the first damper 400 is set in the humidification air duct 111 between the water box 300 and the air curtain outlet 120, the airflow can still flow in the water box 300 and take away some moisture.

[0085] The refrigerator of the embodiment of the present application includes a housing 100, a fan 200, a water box 300, a first air door 400 and a second air door 500. The housing 100 includes a storage chamber, an air duct 110, an air curtain air outlet 120 and a refrigeration air outlet 130. The air duct 110 includes a humidification air duct 111, an air curtain air duct 112 and a refrigeration air duct 113. A storage room for storing articles is formed by arranging a box body 100, and an air duct 110 is formed on the box wall of the box body 100; a fan 200 is arranged to disturb the flow of cold air to form an airflow and drive the airflow into the storage room; a water box 300 is arranged to store humidification liquid; a humidification air duct 111 is arranged and the water box 300 is arranged in the humidification air duct 111 so that the airflow carries the humidification liquid while flowing; an air curtain air duct 112 is arranged to allow the airflow to flow and form a three-dimensional air curtain; an air curtain outlet 120 is arranged to allow the airflow of the humidification air duct 111 and the air curtain air duct 112 to enter the storage room; a refrigeration air duct 113 and a refrigeration air outlet 130 are arranged to allow the airflow to flow and enter the storage room for air cooling. To cool down, a first damper 400 is provided in the humidifying duct 111 between the water box 300 and the air inlet of the air duct 110, so that the on-off state of the humidifying duct 111 between the water box 300 and the air inlet of the air duct 110 is controlled by opening and closing the first damper 400, so as to facilitate regulation according to the humidity in the storage room; a second damper 500 is provided in the refrigerating duct 113, so that the on-off state of the refrigerating duct 113 is controlled by opening and closing the second damper 500, so as to facilitate regulation according to the temperature in the storage room. In this way, the wind curtain function, humidification function and air cooling function of the refrigerator can be driven by providing a fan 200, thereby simplifying the structure of the refrigerator, and the humidification function and air cooling function can be independently regulated, and the control of the refrigerator is more convenient.

[0086] Figure 3 A schematic diagram of the structure of a water box in a refrigerator provided in an embodiment of the present application; Figure 4 for Figure 3 Front view of Figure 5 for Figure 3 Rear view of the . Figures 1 to 5 As shown, in a possible implementation, the water box 300 has a water box air inlet 310 and a water box air outlet 320 which are arranged in sequence along the flow direction of the air flow of the humidification air duct 111, and the water box air inlet 310 and the water box air outlet 320 are respectively located on opposite sides of the water box 300, and the first air gate 400 is located between the air inlet of the air duct 110 and the water box air inlet 310.

[0087] In this way, the water box air inlet 310 and the water box air outlet 320 are arranged at intervals along the air flow direction of the air flow, and the air flow can pass through the water box air inlet 310 and the water box air outlet 320, so that the air flow carries part of the humidification liquid into the storage chamber, thereby increasing the humidity in the storage chamber. Since the water box air inlet 310 and the water box air outlet 320 are respectively located on opposite sides of the water box 300 and along the flow direction of the air flow of the humidification air duct 111, the air flow can go straight in and out of the water box 300, which can not only reduce the flow resistance of the air flow, but also help to simplify the structural design of the water box 300.

[0088] By setting the first damper 400 between the air inlet of the air duct 110 and the water box air inlet 310, when the storage chamber does not need to be humidified, closing the first damper 400 can cut off the path of the airflow entering the water box air inlet 310, and the airflow cannot enter the interior of the water box 300.

[0089] In some embodiments of the present application, the first damper 400 is rotatably connected to the humidification air duct 111 , and / or the second damper 500 is rotatably connected to the refrigeration air duct 113 .

[0090] It should be understood that the first damper 400 may be rotatably connected to the humidification air duct 111, and the second damper 500 may be rotatably connected to the refrigeration air duct 113. Alternatively, the first damper 400 may be rotatably connected to the humidification air duct 111, and the second damper 500 may be openably and closably connected to the refrigeration air duct 113 by other means. Alternatively, the second damper 500 may be rotatably connected to the refrigeration air duct 113, and the first damper 400 may be openably and closably connected to the humidification air duct 111 by other means.

[0091] With such arrangement, the first damper 400 can be rotated relative to the humidification air duct 111 to be in an open state or a closed state, thereby controlling the on / off state of the humidification air duct 111. The second damper 500 can be rotated relative to the refrigeration air duct 113 to control the open / closed state of the second damper 500, thereby controlling the on / off state of the humidification air duct 111.

[0092] The first damper 400 may include a first rotating shaft and a first damper body (not shown in the figure), the first damper body is connected to the first rotating shaft, and the first rotating shaft is rotatably connected to the humidification air duct 111. In order to realize automatic driving of the first damper 400, the refrigerator may also include a first driving member, the first driving member is drivably connected to the first rotating shaft to drive the first rotating shaft to rotate, and then the first rotating shaft synchronously drives the first damper body to rotate relative to the humidification air duct 111, so that the first damper body is opened, and the humidification air duct 111 is in a passage state, or the first damper body is closed, and the humidification air duct 111 is in a disconnected state.

[0093] Similarly, the second damper 500 may include a second rotating shaft and a second damper body (not shown in the figure), the second damper body is connected to the second rotating shaft, and the second rotating shaft is rotatably connected to the refrigeration duct 113. In order to realize automatic driving of the second damper 500, the refrigerator may also include a second driving member, the second driving member is rotatably connected to the second rotating shaft to drive the second rotating shaft to rotate, and then the second rotating shaft synchronously drives the second damper body to rotate relative to the refrigeration duct 113, so that the second damper body is opened, and the refrigeration duct 113 is in a passage state, or the second damper body is closed, and the refrigeration duct 113 is in a disconnected state.

[0094] Figure 6 for Figure 3 AA section view of the Figures 2 to 6 As shown, in some embodiments, the water box 300 includes a box body 330, a partition 340 and a water absorbent 350, and the box body 330 has an inner cavity 331. The partition 340 is configured to separate the inner cavity 331 into a water containing cavity 3311 and a ventilation cavity 3312, the water box air inlet 310 and the water box air outlet 320 are located on opposite sides of the ventilation cavity 3312, and the partition 340 has an avoidance opening. The water absorbent 350 is located in the ventilation cavity 3312 and extends into the water containing cavity 3311 through the avoidance opening.

[0095] Among them, the water holding chamber 3311 is located below the ventilation chamber 3312. The water holding chamber 3311 is used to store humidification liquid. The water absorbent 350 can be extended into the water holding chamber 3311 to absorb the humidification liquid. When the air flow enters the ventilation chamber 3312 through the water box air inlet 310, the air flow blows through the water absorbent 350 and takes away part of the moisture on the water absorbent 350, and then flows out of the ventilation chamber 3312 through the water box air outlet 320, and finally enters the storage room through the wind curtain air outlet 120.

[0096] Exemplarily, the water absorbent member 350 may be a water absorbent sponge, which has more pores, can absorb more humidifying liquid, and has a larger evaporation surface.

[0097] In addition, a water inlet (not shown in the figure) may be provided on the box body 330. Since the water containing cavity 3311 and the ventilation cavity 3312 may be connected through the avoidance port, the water inlet may be provided on the side wall of the box body 330 having the water containing cavity 3311, or the water inlet may be provided on the side wall of the box body 330 having the ventilation cavity 3312. In other words, if the water inlet is provided on the side wall of the box body 330 having the water containing cavity 3311, the humidification liquid may directly enter the water containing cavity 3311 through the water inlet and be stored in the water containing cavity 3311, and the water absorbing member 350 may extend into the water containing cavity 3311 to absorb the humidification liquid. If the water adding port is arranged on the side wall of the box body 330 having the ventilation cavity 3312, the humidifying liquid can first enter the ventilation cavity 3312 through the water adding port, and then sink to the water containing cavity 3311 through the avoidance port, so as to store the humidifying liquid in the water containing cavity 3311. When the humidifying liquid passes through the ventilation cavity 3312, the water absorbent member 350 can absorb part of the humidifying liquid. After the water on the surface of the water absorbent member 350 evaporates, the water absorbent member 350 can extend into the water containing cavity 3311 through the avoidance port to absorb the humidifying liquid.

[0098] Reference Figure 3 As shown, the humidification water box 300 may also include a plugging cover 360 correspondingly arranged at the water inlet. For example, the plugging cover 360 may be threadedly connected to the water inlet, that is, the water inlet is provided with an internal thread, and the outer wall of the plugging cover 360 is provided with an external thread matching the internal thread, and the external thread is screwed on the internal thread. When it is necessary to add humidification liquid, the plugging cover 360 is rotated to disengage the plugging cover 360 from the water inlet, and then the humidification liquid is injected into the water box 300 through the water inlet, and then the plugging cover 360 is rotated again to screw the plugging cover 360 with the water inlet thread and tighten the connection, so that adding water is more convenient.

[0099] In order to make the box body 330 detachably connected to the case body 100, one of the case body 100 and the box body 330 can be provided with a buckle, and the other of the case body 100 and the box body 330 can be provided with a slot. For example, a plurality of buckles are provided along the circumference of the box body 330, and a slot is provided at a corresponding position of the case body 100. The box body 330 can be detachably connected to the case body 100 by snapping the buckles into the slots.

[0100] Reference Figure 1 and Figure 2 As shown, in a possible implementation, the fan 200 is connected to the side wall of the box 100, the refrigeration air duct 113 is located on the side wall of the box 100, and the humidification air duct 111 and the wind curtain air duct 112 extend from the side wall of the box 100 to the top wall of the box 100.

[0101] Since the evaporator 700 is arranged on the side wall of the cabinet 100 and is located below the fan 200, arranging the refrigerated air duct 113 on the side wall of the cabinet 100 can shorten the flow path of the refrigerated air duct 113 to reduce the cold loss during the flow of the air flow, and arranging the refrigerated air outlet 130 on the rear side wall of the cabinet 100 can make the refrigerated air duct 113 discharge air from the rear side of the storage room and then blow it evenly to the front side of the storage room. Such an arrangement can achieve a better air cooling effect in the storage room.

[0102] Since the wind curtain outlet 120 is located on the front side of the box body 100 close to the door body 600, and the humidification air duct 111 and the wind curtain air duct 112 both need to discharge air through the wind curtain outlet 120, the humidification air duct 111 and the wind curtain air duct 112 need to extend from the side wall of the box body 100 to the top wall of the box body 100, thereby forming the wind curtain outlet 120 on the front side of the top wall of the box body 100.

[0103] Among them, the fan 200 can be arranged in the central part of the rear side wall of the box body 100, and the humidification air duct 111, the wind curtain air duct 112 and the refrigeration air duct 113 are radially arranged on the surrounding side of the fan 200, so that one fan 200 can provide airflow for the humidification air duct 111, the wind curtain air duct 112 and the refrigeration air duct 113 at the same time.

[0104] Figure 7 A schematic diagram of the top structure of a refrigerator box provided in an embodiment of the present application; Figure 8 This is a schematic diagram of the side structure of the refrigerator provided in the embodiment of the present application. Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, in some embodiments of the present application, the side wall of the box body 100 has a first flow cavity 140, and the top wall of the box body 100 has a second flow cavity 150 and two third flow cavities 160, the two third flow cavities 160 are located on opposite sides of the second flow cavity 150 along the thickness direction of the box body 100, the first flow cavity 140 and the second flow cavity 150 together form a humidification air duct 111, and the first flow cavity 140 and the third flow cavity 160 together form a wind curtain air duct 112.

[0105] That is to say, the parts of the humidification duct 111 and the wind curtain duct 112 on the side wall of the box body 100 can be connected to each other, while the parts of the humidification duct 111 and the wind curtain duct 112 on the top wall of the box body 100 can be isolated from each other. The fan 200 drives the airflow to flow along the first flow cavity 140. When it flows to the junction of the side wall of the box body 100 and the top wall of the box body 100, it begins to diverge. Then the airflow flows along the second flow cavity 150 and the third flow cavity 160 to the wind curtain outlet 120 respectively. In this way, the structural design of the air duct 110 on the side wall of the box body 100 can be simplified.

[0106] In the specific setting, a plurality of guides may be arranged in the first circulation cavity 140 so that the airflow flows in different directions along the guides. For example, a guide may be arranged on the side of the side wall of the box body 100 close to the top wall of the box body 100 so that the airflow begins to diverge when it flows to the junction of the side wall of the box body 100 and the top wall of the box body 100, and then when entering the top wall of the box body 100, the airflow flows along the second circulation cavity 150 and the third circulation cavity 160 respectively. Since the second circulation cavity 150 is provided with a first damper 400, the first damper 400 can control the on-off state of the second circulation cavity 150, and then the second circulation cavity 150 and the third circulation cavity 160 can be in the passage state at the same time, or the second circulation cavity 150 is in the off-circuit state and the third circulation cavity 160 is in the passage state.

[0107] A guide member for guiding the airflow to the refrigerated air outlet 130 may also be provided in the first circulation cavity 140. In this way, the flow direction of the airflow is guided by the guide member so that the airflow coming out of the fan 200 flows in different directions to the wind curtain outlet 120 and the refrigerated air outlet 130 respectively.

[0108] Reference Figure 1 As shown, in some embodiments of the present application, the refrigeration air duct 113 includes a first refrigeration air duct 1131 and a second refrigeration air duct 1132, and the airflow directions of the first refrigeration air duct 1131 and the second refrigeration air duct 1132 are opposite. In this way, the airflow can enter the storage room from the refrigeration air outlets 130 at different positions, thereby evenly cooling the storage room.

[0109] It should be noted that the storage chamber can be divided into different storage spaces for storing different items. For example, a plurality of shelves can be arranged above the storage chamber to form a plurality of storage layers, and two drawers can be arranged below the storage chamber. The two drawers are arranged at intervals along the width direction of the refrigerator to form a temperature-changing drawer and a dry and wet drawer arranged side by side, wherein the airflow in the first refrigeration duct 1131 flows toward the top of the cabinet 100 to lower the temperature of each storage layer, and the airflow in the second refrigeration duct 1132 flows toward the bottom of the cabinet 100 to lower the temperature of the drawer.

[0110] Among them, a second air door 500 can be set in the first refrigeration air duct 1131 and the second refrigeration air duct 1132 to respectively control the on-off state of the first refrigeration air duct 1131 and the on-off state of the second refrigeration air duct 1132. In this way, the storage layer, the temperature-variable drawer and the dry-wet drawer can form a space with independent temperature control, so that the user can adjust the temperature of the storage layer, the temperature-variable drawer and the dry-wet drawer according to storage needs.

[0111] It should be noted that the box body 100 may also have a return air outlet (not shown in the figure), which is located at the bottom of the storage room. The airflow entering the storage room from the wind curtain outlet 120 and the refrigerated air outlet 130 can eventually flow back to the evaporator 700 through the return air outlet, and after heat exchange and cooling with the evaporator 700, it can re-enter the storage room from the wind curtain outlet 120 and / or the refrigerated air outlet 130.

[0112] Fig. 9 Schematic diagram of the refrigerator control method provided in the embodiment of the present application Figure 1 . Reference Fig. 9 As shown, the embodiment of the present application also provides a refrigerator control method, which is applied to the refrigerator provided by the above embodiment, and the method includes:

[0113] S101. Determine the temperature and humidity inside a storage compartment of a refrigerator.

[0114] Among them, a temperature detection unit and a humidity detection unit can be set inside the storage room, and both the temperature detection unit and the humidity detection unit are electrically connected to the control unit of the refrigerator. The temperature detection unit detects and obtains the current temperature value inside the storage room, and the humidity detection unit detects and obtains the current humidity value inside the storage room, and feeds back to the control unit of the refrigerator to compare the current humidity value with the preset humidity threshold. When the humidity value is lower than the preset humidity threshold, the control unit controls the first damper 400 to open; when the humidity value is higher than or equal to the preset humidity threshold, the control unit controls the first damper 400 to close, and compares the current temperature value with the preset temperature threshold. When the temperature value is lower than the preset temperature threshold, the second damper 500 is controlled to open; when the temperature value is lower than or equal to the preset temperature threshold, the second damper 500 is controlled to close.

[0115] S102: If the humidity value is lower than the preset humidity threshold, control the first damper 400 to open.

[0116] In this way, when the humidity detection unit detects that the humidity value is lower than the preset humidity threshold, it means that the interior of the storage room needs to be humidified, and the humidity detection unit feeds back the detection result to the control unit, and the control unit controls the first damper 400 to open. When the first damper 400 is opened, the humidification air duct 111 is in a passage state, and the fan 200 drives the air flow to flow along the humidification air duct 111 and enter the storage room through the air curtain outlet 120. The air flow humidity in the humidification air duct 111 is high, so that the air humidity inside the storage room can be increased to increase the humidity value to the preset humidity threshold.

[0117] S103: If the temperature value is higher than the preset temperature threshold, the second damper 500 is controlled to open.

[0118] Thus, when the temperature detection unit detects that the temperature value is higher than the preset temperature threshold, it indicates that the interior of the storage room needs air cooling, and the temperature detection unit feeds back the detection result to the control unit, and the control unit controls the second air door 500 to open. When the second air door 500 is opened, the refrigeration air duct 113 is in a passage state, and the fan 200 drives a large amount of air flow to flow along the refrigeration air duct 113 and enter the storage room through the refrigeration air outlet 130, thereby quickly reducing the air temperature inside the storage room to reduce the temperature value to the preset temperature threshold.

[0119] Fig.10 Schematic diagram of the refrigerator control method provided in the embodiment of the present application Figure 2 . Reference Fig.10 As shown, specifically, S102, if the humidity value is lower than the preset humidity threshold, controlling the first damper 400 to open includes:

[0120] S1021. Determine the open or closed state of the door 600 of the refrigerator.

[0121] S1022: If the door body 600 is in a closed state and the humidity value is lower than a preset humidity threshold, the first damper 400 is controlled to open.

[0122] It should be noted that since the wet mist flows out from the wind curtain outlet 120, that is, it is mixed with the three-dimensional wind curtain on the front side of the storage room, before humidifying the storage room, it is necessary to first determine the open or closed state of the door body 600 to avoid the user standing in front of the storage room at this time, so as to avoid the moisture in the wet mist from sticking to the user.

[0123] If the door body 600 is in the open state, it means that there is a user standing in front of the storage room. At this time, the airflow blown out from the wind curtain outlet 120 should form a three-dimensional wind curtain to prevent the loss of cold air. However, the airflow blown out from the wind curtain outlet 120 should not contain too much moisture to avoid it getting on the user's body and causing a poor user experience. Therefore, at this time, no matter what the humidity value in the storage room is (for example, before opening the door body 600, the first air door 400 is in the open state, and the water box 300 is humidifying the storage room), the first air door 400 should be temporarily closed to keep the humidification air duct 111 in an open state, so that the gas blown out from the wind curtain outlet 120 contains less moisture.

[0124] If the door body 600 is in a closed state and the humidity value is lower than the preset humidity threshold, the storage room can be safely humidified to increase the humidity value in the storage room.

[0125] It should be noted that no matter whether the door body 600 is in an open state or a closed state, the wind curtain outlet 120 can always form a three-dimensional wind curtain from top to bottom to isolate the loss of cold air, and the refrigerated air outlet 130 can provide airflow to the rear side of the storage room to evenly cool the storage room according to the temperature control needs.

[0126] In addition, when the storage chamber does not need humidification and air cooling, the first damper 400 and the second damper 500 can be closed at the same time, or the fan 200 can be controlled to be closed.

[0127] An embodiment of the present application also provides a control device for a refrigerator. The control device for a refrigerator provided in this embodiment may include a control unit and a detection unit. The detection unit may include a humidity detection unit and a temperature detection unit.

[0128] Among them, the temperature detection unit is used to determine the temperature value inside the storage chamber of the refrigerator, the humidity detection unit is used to determine the humidity value inside the storage chamber, and the control unit is used to control the first damper 400 to open when the humidity value is lower than the preset humidity threshold, and control the second damper 500 to open when the temperature value is lower than the preset temperature threshold.

[0129] In some implementations, the detection unit may further include a door detection unit, which is used to determine the open and closed state of the door 600 and feed back the detection result to the control unit, and the control unit is also used to control the first damper 400 to open when the door 600 is in a closed state and the humidity value is lower than a preset humidity threshold. Alternatively, the control unit is also used to control the first damper 400 to close when the door 600 is in an open state and the first damper 400 is in an open state.

The refrigerator of the embodiment of the present application provides airflow for the humidification air duct 111, the air curtain air duct 112 and the refrigeration air duct 113 by setting the fan 200, and then provides power for the humidification, air curtain and air cooling of the refrigerator at the same time. By setting the first air door 400 in the humidification air duct 111, the on-off state of the humidification air duct 111 is controlled by controlling the opening and closing state of the first air door 400, so as to adjust the humidity in the storage room. By setting the second air door 500 in the refrigeration air duct 113, the on-off state of the refrigeration air duct 113 is controlled by controlling the opening and closing state of the second air door 500, so as to adjust the temperature in the storage room. The first air door 400 and the second air door 500 can be controlled independently. Therefore, the temperature and humidity of the refrigerator are more convenient to control.
