[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0029] refer to Figures 1 to 3 As shown, in some embodiments of the refrigerator provided by the utility model, the refrigerator includes a cabinet 1, a cabinet door, a first detection device, a second detection device and an adjustment device, the cabinet 1 is used to store items, the cabinet door can be opened and closed on the cabinet 1, the first detection device is configured to detect whether the cabinet door is opened, the second detection device is configured to detect the working temperature target value in the cabinet 1, the adjustment device is signal-connected with the first detection device and the second detection device, and the adjustment device is configured to determine the humidity adjustment target according to whether the cabinet door is opened detected by the first detection device and the working temperature target value in the cabinet 1 detected by the second detection device.

[0030] In the above embodiment, the regulating device determines the humidity regulation target based on whether the cabinet door is opened as detected by the first detection device and the working temperature target value in the cabinet 1 as detected by the second detection device. This can make the determined humidity regulation target more accurate, which is conducive to more accurate and effective regulation of the humidity in the cabinet 1, achieving better dehumidification effect, reducing frost in the cabinet 1, solving the problem of secondary frost caused by frosting and accumulation of defrost water, and improving the heat exchange efficiency and operation reliability of the refrigerator.

[0031] Moreover, by determining different humidity adjustment targets based on whether the door is opened and the different target working temperature values ​​in the cabinet 1, the humidity adjustment can correspond to different adjustment targets under different conditions, so that the humidity adjustment can adapt to the current working state of the refrigerator, which is conducive to improving the adaptability of the humidity, improving the humidity adjustment effect, and meeting the different needs of different scenarios.

[0032] In some embodiments, the refrigerator further includes a humidity regulating structure, the regulating device is signal-connected to the humidity regulating structure, and the regulating device is configured to open the humidity regulating structure to perform humidity regulation after determining a humidity regulation target.

[0033] By setting the humidity adjustment structure, humidity adjustment can be achieved by opening the humidity adjustment structure after determining the humidity adjustment target.

[0034] There are many options for the specific implementation of the humidity adjustment structure.

[0035] In some embodiments, the refrigerator also includes a storage chamber 2, a cooling air duct 3 and a return air duct arranged in the box body 1, the storage chamber 2 is used to store items, the cooling gas in the cooling air duct 3 is used to cool the items, and the return air duct is used to discharge the gas after cooling the items.

[0036] Cooling gas flows in the cooling air duct 3 , and the cooling gas cools down the items in the storage chamber 2 . The cooled gas is discharged through the return air duct.

[0037] In some embodiments, the refrigerator further includes a refrigeration component, which is used to cool the gas, and the cooled gas enters the cooling air duct 3.

[0038] like Figure 2 As shown, the refrigerator also includes a cold conduction plate 7 arranged between the cooling air duct 3 and the storage chamber 2. The cooling gas is blown toward the cold conduction plate 7. After the cold conduction plate 7 is cooled, it exchanges heat with the objects in the storage chamber 2 to achieve the effect of cooling the objects.

[0039] In some embodiments, the humidity adjustment structure includes a damper 4 disposed on the return air duct, and when the damper 4 is in an open state, the water vapor in the box 1 enters the return air duct.

[0040] By setting a damper 4 on the return air duct, after opening the damper 4, the rapid flow of return air in the return air duct will form a negative pressure in the return air duct. Therefore, under the action of the pressure difference, the water vapor in the box 1 can diffuse into the return air duct, thereby achieving the effect of dehumidifying the box 1.

[0041] In some embodiments, the temperature of the return air in the return air duct is lower than the temperature of the gas in the box 1, which can enhance the dehumidification effect.

[0042] In some embodiments, the humidity regulating structure further includes a first driving device, which is drivingly connected to the damper 4 and is configured to drive the damper 4 to move relative to the return air duct so that the damper 4 is opened or closed.

[0043] By providing the first driving device, the damper 4 can be driven to move relative to the return air duct to achieve opening or closing of the damper 4.

[0044] In some embodiments, the first driving device may be configured to drive the damper 4 to rotate relative to the return air duct, so as to open or close the damper 4 by rotation.

[0045] In other embodiments, the first driving device may be configured to drive the damper 4 to translate relative to the return air duct, so as to open or close the damper 4 by means of up-and-down or left-and-right translation.

[0046] The first driving device can be an oil cylinder, an air cylinder or a motor.

[0047] By providing the first driving device, the adjusting device can realize the opening and closing of the damper 4 by adjusting the first driving device.

[0048] In some embodiments, the humidity adjustment structure includes ventilation holes 5 disposed on the side wall of the cooling air duct 3 , and the ventilation holes 5 connect the cooling air duct 3 and the storage chamber 2 .

[0049] By arranging ventilation holes 5 on the side wall of the cooling air duct 3, the cooling air duct 3 and the storage chamber 2 can be connected when the ventilation holes 5 are opened, so that the cooling gas in the cooling air duct 3 can enter the storage chamber 2 through the ventilation holes 5, thereby reducing the humidity in the storage chamber 2.

[0050] By providing the ventilation holes 5, the cooling gas is introduced into the storage chamber 2, thereby achieving the effect of induced dehumidification.

[0051] In some embodiments, the humidity regulating structure further includes a sealing plate and a second driving device, the second driving device is drivingly connected to the sealing plate, and the second driving device is configured to drive the sealing plate to move relative to the cooling air duct 3 to open or close the ventilation hole 5.

[0052] By providing the sealing plate and the second driving device, the sealing plate can be driven to move by the second driving device to realize opening or closing of the ventilation hole 5 .

[0053] In some embodiments, the second driving device may be configured to drive the sealing plate to rotate relative to the cooling air duct 3 so as to open or close the ventilation hole 5 by rotation.

[0054] In other embodiments, the second driving device may be configured to drive the sealing plate to translate relative to the cooling air duct 3 so as to open or close the ventilation hole 5 by means of up-and-down or left-and-right translation.

[0055] The second driving device can be an oil cylinder, an air cylinder or a motor.

[0056] By providing the second driving device, the adjusting device can realize the opening and closing of the ventilation hole 5 by adjusting the second driving device.

[0057] The shape of the ventilation hole 5 can be circular, square or other shapes.

[0058] The flow area of ​​the ventilation hole 5 is constructed to be able to adjust the humidity in the box body 1 without affecting the moisture content of the items in the box body 1, preventing the cooling gas from taking away the moisture on the surface of the items and affecting the quality of the items.

[0059] In some embodiments, the regulating device is configured to determine the humidity regulating target according to the working temperature target value in the cabinet 1 when the first detecting device detects that the cabinet door is opened.

[0060] In some embodiments, the target working temperature value in the box 1 includes above 0°C. At this time, the box 1 can be used to store fruits and vegetables. The adjustment device is configured to determine the humidity adjustment target to be less than or equal to the first preset value when the target working temperature value in the box 1 is above 0°C.

[0061] In some embodiments, the first preset value can be 70%. Controlling the humidity of fruits and vegetables within 70% can effectively maintain the freshness of fruits and vegetables and ensure the moisture content of fruits and vegetables. At the same time, it can effectively reduce frost in the box 1 and improve the heat exchange efficiency and operation reliability of the refrigerator.

[0062] In some embodiments, the working temperature target value in the box 1 includes 0°C and below. At this time, the box 1 can be used to store fresh meat items. The adjustment device is configured to determine the humidity adjustment target to be the humidity in the box 1 less than or equal to a second preset value when the working temperature target value in the box 1 is 0°C and below, wherein the second preset value is a humidity preset value determined according to the floating temperature value, and the floating temperature value is the sum of the temperature in the box 1 after the door is opened and closed and the preset temperature value.

[0063] By setting the second preset value to the humidity preset value determined according to the floating temperature value, the magnitude of the humidity adjustment target value can be appropriately reduced, thereby effectively avoiding secondary frosting or refreezing and ensuring the freezing quality of meat products.

[0064] Among them, there are various choices for the specific implementation manner of determining the second preset value according to the floating temperature value.

[0065] In some embodiments, the preset temperature value is 5°C to 7°C, such as 5°C, 6°C, and 7°C.

[0066] In some embodiments, the correspondence between the floating temperature value and the second preset value is set as follows:

[0067] When the floating temperature value T1 satisfies 0°C < T1 ≤ 1.5°C, the second preset value is 70%;

[0068] When the floating temperature value T1 satisfies 1.5°C < T1 ≤ 2.5°C, the second preset value is 60%;

[0069] When the floating temperature value T1 satisfies 2.5°C < T1 ≤ 6°C, the second preset value is 50%;

[0070] When the floating temperature value T1 satisfies T1 > 6°C, the second preset value is 40%.

[0071] In some embodiments, the refrigerator further includes a temperature detection device configured to detect the temperature inside the cabinet 1. The working temperature target value inside the cabinet 1 includes floating around 0°C (such as -2°C to 2°C). At this time, the cabinet 1 can be used to store seafood products. The adjustment device is configured to determine that the humidity adjustment target is that the humidity inside the cabinet 1 is less than or equal to the first preset value when the working temperature target value inside the cabinet 1 is floating around 0°C (such as -2°C to 2°C) and the temperature inside the cabinet 1 is greater than 0°C; and determine that the humidity adjustment target is that the humidity inside the cabinet 1 is less than or equal to the third preset value when the working temperature target value inside the cabinet 1 is floating around 0°C (such as -2°C to 2°C) and the temperature inside the cabinet 1 is less than or equal to 0°C, where the third preset value is the humidity preset value determined according to the temperature difference between the temperature at the moment when the cabinet door is opened and the temperature inside the cabinet 1 after the cabinet door is opened and then closed.

[0072] In this embodiment, the working temperature target value inside the cabinet 1 includes floating around 0°C (such as -1°C to 1°C or -2°C to 2°C). According to whether the actual temperature inside the cabinet 1 is greater than 0°C, it is divided into two humidity adjustment methods, which can achieve more accurate and targeted humidity adjustment and better effects.

[0073] In this embodiment, the first preset value can be 70%.

[0074] By setting the third preset value to the humidity preset value determined according to the temperature difference between the temperature at the moment when the box door is opened and the temperature inside the box body 1 after the box door is opened and then closed, a more accurate and humidity adjustment target adapted to the actual operation situation inside the box body 1 can be determined, thereby effectively improving the dehumidification effect and ensuring the refrigeration quality of seafood items.

[0075] Among them, there can be multiple choices for the specific implementation manner of determining the third preset value according to the temperature difference between the temperature at the moment when the box door is opened and the temperature inside the box body 1 after the box door is opened and then closed.

[0076] In some embodiments, the correspondence relationship between the temperature difference between the temperature at the moment when the box door is opened and the temperature inside the box body 1 after the box door is opened and then closed and the third preset value is set as follows:

[0077] When the temperature difference T2 satisfies 0°C < T2 ≤ 0.5°C, the third preset value is 70%;

[0078] When the temperature difference T2 satisfies 0.5°C < T2 ≤ 1.5°C, the third preset value is 60%;

[0079] When the temperature difference T2 satisfies 1.5°C < T2 ≤ 5°C, the third preset value is 50%;

[0080] When the temperature difference T2 satisfies T2 > 5°C, the third preset value is 40%.

[0081] Among them, T2 = the temperature T inside the box body 1 after the box door is opened and then closed 关 - the temperature T at the moment when the box door is opened 开 。

[0082] In some embodiments, the refrigerator further includes a refrigeration component, the refrigeration component is configured to provide cooling gas for cooling items, the working temperature target value inside the box body 1 includes 0°C and below and -2°C to 2°C, and the adjustment device is further configured to lower the temperature inside the box body 1 by 1°C to 2°C when the refrigeration component stops operating when the working temperature target value inside the box body 1 is 0°C and below and -2°C to 2°C.

[0083] By lowering the temperature inside the box body 1 when the refrigeration component stops operating, the temperature inside the box body 1 can be made lower when the refrigeration component stops operating, which is more conducive to humidity adjustment. Moreover, after the stop temperature of the refrigeration component is lowered, the refrigeration time of the refrigeration component will become longer, which is more beneficial to the dehumidification effect.

[0084] In some embodiments, the refrigerator further includes a humidity detection device 6, and the humidity detection device 6 is configured to detect the humidity inside the box body 1.

[0085] By providing the humidity detection device 6, the humidity inside the box body 1 can be detected in real time, so as to determine a suitable adjustment target according to the humidity level.

[0086] In some embodiments, the humidity detection device 6 is disposed near the air damper 4, which is conducive to improving the accuracy of humidity detection. The temperature detection device may also be disposed near the air damper 4.

[0087] In some embodiments, the adjustment device is in signal connection with the humidity detection device 6. The adjustment device is configured to determine whether to initiate humidity adjustment according to the humidity recovery rate inside the cabinet 1 when the first detection device does not detect an opening action of the cabinet door, and to determine the humidity adjustment target according to the working temperature target value inside the cabinet 1 when the determination result is that humidity adjustment needs to be initiated.

[0088] When the cabinet door does not have an opening action, that is, when the cabinet door remains closed all the time, it is determined whether to initiate humidity adjustment by detecting the humidity recovery rate inside the cabinet 1. When the determination result is that humidity adjustment needs to be initiated, the adjustment device determines the humidity adjustment target according to the working temperature target value inside the cabinet 1; when the determination result is that humidity adjustment does not need to be initiated, the air damper 4 and the ventilation hole 5 remain closed.

[0089] Among them, the specific operation of determining whether to initiate humidity adjustment may be to determine whether the humidity recovery rate D inside the cabinet 1 is greater than or equal to the preset rate D1. If D≥D1, it is determined that humidity adjustment needs to be initiated; if D<D1, it is determined that humidity adjustment does not need to be initiated.

[0090] As Figure 3 shown, based on the refrigerator in the above embodiments, the dehumidification steps of the refrigerator provided by the present utility model include:

[0091] Detecting whether the cabinet door has an opening action;

[0092] Detecting the working temperature target value inside the cabinet 1; and

[0093] Determining the humidity adjustment target according to whether the cabinet door has an opening action detected by the first detection device and the working temperature target value inside the cabinet 1 detected by the second detection device.

[0094] In some embodiments, the operation of determining the humidity adjustment target according to whether the cabinet door has an opening action detected by the first detection device and the working temperature target value inside the cabinet 1 detected by the second detection device includes:

[0095] When the first detection device detects an opening action of the cabinet door, determining the humidity adjustment target according to the working temperature target value inside the cabinet 1;

[0096] When the first detection device does not detect that the door is opened, whether humidity adjustment needs to be started is determined based on the humidity recovery rate in the box 1. When the judgment result is that humidity adjustment needs to be started, the humidity adjustment target is determined based on the working temperature target value in the box 1.

[0097] In some embodiments, when the first detection device detects that the door is opened, the operation of determining the humidity adjustment target according to the working temperature target value in the box body 1 includes:

[0098] When the target working temperature in the box 1 is above 0°C, the humidity adjustment target is determined to be that the humidity in the box 1 is less than or equal to a first preset value;

[0099] When the target working temperature in the box 1 is 0°C or below, the humidity adjustment target is determined to be that the humidity in the box 1 is less than or equal to a second preset value, wherein the second preset value is a humidity preset value determined according to the floating temperature value, and the floating temperature value is the sum of the temperature in the box 1 after the door is opened and closed and the preset temperature value, and the preset temperature value is 5°C to 7°C;

[0100] When the working temperature target value in the cabinet 1 is -2℃~2℃, if the temperature in the cabinet 1 is greater than 0℃, the humidity adjustment target is determined to be the humidity in the cabinet 1 less than or equal to the first preset value; if the temperature in the cabinet 1 is less than or equal to 0℃, the humidity adjustment target is determined to be the humidity in the cabinet 1 less than or equal to the third preset value, wherein the third preset value is a humidity preset value determined based on the temperature difference between the temperature at the moment the cabinet door is opened and the temperature in the cabinet 1 after the cabinet door is opened and closed.

[0101] like Figure 3 As shown, in one embodiment, the dehumidification step of the refrigerator includes:

[0102] When the door is detected to be open, the function control status in the current cabinet 1 is determined immediately. If the target working temperature in the cabinet 1 is above 0°C, the functional area in the cabinet 1 is the fruit and vegetable storage area Q1; if the target working temperature in the cabinet 1 is 0°C or below, the functional area in the cabinet 1 is the fresh meat storage area Q2; if the target working temperature in the cabinet 1 fluctuates above and below 0°C (for example, -1°C to 1°C or -2°C to 2°C), the functional area in the cabinet 1 is the seafood storage area Q3;

[0103] When the functional area in the box body 1 is Q1, the damper 4 and the ventilation hole 5 are opened until the humidity in the box body 1 satisfies d≤d1, and the damper 4 and the ventilation hole 5 are closed.

[0104] When the functional area in the cabinet 1 is Q2, the temperature value T1 is detected (T1=the temperature value in the cabinet 1 after the door is closed+6°C), and the second preset value d2 is determined according to the T1 value. At this time, the damper 4 and the vent 5 are opened, the shutdown temperature of the refrigeration component is lowered by 1°C to 2°C, and the refrigeration operation is performed until the humidity in the cabinet 1 satisfies d≤d2, the damper 4 and the vent 5 are closed, and the temperature control point in the cabinet 1 is switched to the original set value control operation;

[0105] When the functional area in the cabinet 1 is Q3, if the current temperature T in the cabinet 1 is greater than 0°C, the damper 4 and the vent 5 are opened until the humidity in the cabinet 1 satisfies d≤d1, and the damper 4 and the vent 5 are closed; if the current temperature in the cabinet 1 is T≤0°C, the temperature difference T2 before and after the cabinet door is opened and closed is detected, and the third preset value d3 is determined according to the value of T2. At this time, the damper 4 and the vent 5 are opened, the shutdown temperature of the refrigeration component is lowered by 1°C to 2°C, and the refrigeration operation is performed until the humidity in the cabinet 1 satisfies d≤d3, the damper 4 and the vent 5 are closed, and the temperature control point in the cabinet 1 is switched to the original set value control operation;

[0106] When it is detected that the door is not opened, it is determined whether the humidity recovery rate D in the current cabinet 1 satisfies D≥D1. If so, the aforementioned humidity adjustment program is entered; if not, the damper 4 and the ventilation hole 5 remain closed until the refrigerator door is opened or the humidity recovery rate changes.

[0107] The embodiment of the utility model detects the opening and closing conditions of the cabinet door and the working conditions inside the cabinet, and in combination with the temperature and humidity changes inside the cabinet, opens the damper and the ventilation holes to make the humidity inside the cabinet lower than the preset value, thereby achieving the effect of induced dehumidification at low temperature, solving the problems of excessive humidity inside the cabinet and easy frost on the wall due to frequent opening and closing of the door, and improving the heat exchange efficiency and operation reliability of the refrigerator.
