Technical Field

[0001] The present disclosure relates to the field of household appliances, and in particular to a refrigerator. Background Art

[0002] As people's living standards continue to improve, refrigerators have become a necessity in people's lives. Refrigerators can store food in a certain temperature environment and keep the food fresh. With the increasing requirements for food preservation, the accuracy of temperature control is getting higher and higher, especially the supercooling storage technology of food has very high requirements for the refrigerator temperature.

[0003] In the related art, since the supercooling state of food is relatively unstable, if it suddenly encounters a low-temperature, high-flow airflow, it is easy to break the supercooling state and cause the food to freeze, resulting in food damage. Utility Model Content

[0004] In view of this, the present disclosure provides a refrigerator capable of automatically adjusting the cooling capacity according to the intensity of cold wind.

[0005] Specifically, the present disclosure is implemented through the following technical solutions.

[0006] According to a first aspect of an embodiment of the present disclosure, a refrigerator is provided, comprising a storage chamber, a baffle and a drive assembly. The storage chamber is provided with a accommodating cavity and an air duct connected to the accommodating cavity. The baffle is movably arranged in the storage chamber, and has a closed state that closes at least part of the air duct. The drive assembly comprises an airbag and a transmission member connected to the airbag. At least part of the airbag is located in the air duct. The transmission member is connected to the baffle. When the airflow temperature of the air duct is lower than a preset temperature, the airbag can shrink or expand to drive at least part of the transmission member to shrink or expand, and the transmission member drives the baffle to move so that the baffle is in a closed state.

[0007] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects.

[0008] When the refrigerator is working, the airflow is blown into the storage chamber through the air duct to store the food in the storage chamber in a certain temperature environment to keep the food fresh. When the airflow temperature in the air duct is lower than the preset temperature, the airbag arranged in the air duct can shrink or expand, and the airbag is connected to the transmission member, so that the transmission member also shrinks or expands. The transmission member is connected to the baffle, so that the transmission member drives the baffle to move, and the baffle closes at least part of the air duct, thereby reducing the amount of airflow entering the storage chamber and reducing the amount of cold air in the storage chamber. Prevent the food in the storage chamber from being frozen by the low-temperature and high-flow airflow. Ensure the freshness of the food and improve the reliability of the refrigerator.

[0009] The technical solution of the present disclosure is further described below.

[0010] In one embodiment, the transmission member includes a telescopic portion and a connecting portion connected to the telescopic portion. The telescopic portion is hollow, and the telescopic portion is communicated with the airbag, and the telescopic portion is connected to the stopper through the connecting portion.

[0011] In one embodiment, when the air flow temperature of the air duct is lower than a preset temperature, the volume of the gas in the airbag shrinks to shrink the telescopic portion, and the telescopic portion pulls the stopper through the connecting portion.

[0012] In one embodiment, the telescopic portion and the blocking member are respectively arranged on both sides of the air duct, so that when the telescopic portion contracts, the blocking member can be pulled to move in a direction close to the air duct.

[0013] In one embodiment, when the air flow temperature of the air duct is lower than a preset temperature, the volume of the gas in the airbag expands to expand the telescopic portion, and the telescopic portion pushes the stopper through the connecting portion.

[0014] In one embodiment, the telescopic portion and the blocking member are disposed on the same side of the air duct, and the blocking member is disposed closer to the air duct relative to the telescopic portion, so that when the telescopic portion expands, it can push the blocking member to move in a direction closer to the air duct.

[0015] In one embodiment, the refrigerator includes a fresh-keeping chamber, and the storage chamber is the fresh-keeping chamber.

[0016] In one embodiment, the refrigerator further comprises a telescopic member, which is disposed around the inner wall of the air duct. When the air flow temperature of the air duct is lower than a preset temperature, the telescopic member can be retracted to close at least part of the air duct.

[0017] In one embodiment, the refrigerator further includes an elastic member, which is disposed around the inner wall of the air duct, and the elastic member is fixedly connected to the inner wall of the air duct, and the elastic member is fixedly connected to the telescopic member.

[0018] In one embodiment, the elastic member is sandwiched between the inner wall of the air duct and the telescopic member.

[0032] As people's living standards continue to improve, refrigerators have become a necessity in people's lives. Refrigerators can store food in a certain temperature environment and keep the food fresh. With the increasing requirements for food preservation, the accuracy of temperature control is getting higher and higher, especially the supercooling storage technology of food has very high requirements for the refrigerator temperature.

[0033] In the related art, there are many methods for supercooling food, such as electromagnetic field technology, but since the supercooling state of food is relatively unstable, if it suddenly encounters low-temperature and high-flow airflow, it is easy to break the supercooling state and cause the food to freeze, resulting in food damage.

[0034] Based on this, the present disclosure provides a refrigerator that can automatically adjust the cooling capacity according to the cold wind intensity, thereby preventing the low-temperature and high-flow airflow from damaging the food in the refrigerator and improving the reliability of the refrigerator.

[0035] like Figures 1 to 3 As shown, the refrigerator 10 includes a storage chamber 100, a blocking member 200 and a driving assembly 300. The storage chamber 100 is provided with a receiving cavity 110 and an air duct 120 communicated with the receiving cavity 110. The blocking member 200 is movably arranged in the storage chamber 100, and has a closed state of closing at least part of the air duct 120. The driving assembly 300 includes an airbag 310 and a transmission member 320 communicated with the airbag 310. At least part of the airbag 310 is located in the air duct 120. The transmission member 320 is connected to the blocking member 200. When the air flow temperature of the air duct 120 is lower than a preset temperature, the airbag 310 can shrink or expand to drive at least part of the transmission member 320 to shrink or expand, and the transmission member 320 drives the blocking member 200 to move so that the blocking member 200 is in a closed state.

[0036] In this way, when the refrigerator 10 is working, the airflow is blown into the accommodating cavity 110 of the storage chamber 100 through the air duct 120 to store the food in the accommodating cavity 110 in a certain temperature environment to maintain the freshness of the food. When the airflow temperature of the air duct 120 is lower than the preset temperature, the airbag 310 arranged in the air duct 120 can shrink or expand, and the airbag 310 is connected to the transmission member 320, so that the transmission member 320 also shrinks or expands. The transmission member 320 is connected to the baffle 200, so that the transmission member 320 drives the baffle 200 to move, and the baffle 200 closes at least part of the air duct 120, thereby reducing the amount of airflow entering the accommodating cavity 110 and reducing the amount of cold air in the accommodating cavity 110. Avoid freezing of the food in the accommodating cavity 110 due to the low-temperature and large-flow airflow. The freshness of the food is guaranteed and the reliability of the refrigerator 10 is improved. When the air flow temperature of the air duct 120 returns to the preset temperature, the airbag 310 also returns to its original state, so that the transmission member 320 returns to its original state and drives the blocking member 200 to open the air duct 120, so that the air flow flows into the accommodating chamber 110 again to preserve the food in the storage chamber 100.

[0037] Optionally, the airbag 310 and the transmission member 320 are detachably fixedly connected, for example, by screwing, clamping, etc.

[0038] It should be noted that the storage chamber 100 may be a refrigeration chamber, a fresh-keeping chamber, etc. of the refrigerator 10 .

[0039] In some embodiments, the storage chamber 100 is a fresh-keeping chamber of the refrigerator 10 .

[0040] It is understandable that the cold air of the fresh-keeping room can be generated by the freezing room and transferred to the fresh-keeping room by the freezing room. It can also be that the fresh-keeping room is provided with a refrigeration device, and the refrigeration device transfers the cold air to the fresh-keeping room.

[0041] like Figure 3 as well as Figure 4 As shown, in some embodiments, the transmission member 320 includes a telescopic portion 321 and a connecting portion 322 connected to the telescopic portion 321. The telescopic portion 321 is hollow, and the telescopic portion 321 is connected to the airbag 310, and the telescopic portion 321 is connected to the blocking member 200 through the connecting portion 322. In this way, when the airflow temperature of the air duct 120 is lower than the preset temperature, after the airflow blows to the airbag 310, the airbag 310 shrinks or expands, and the telescopic portion 321 is connected to the airbag 310, so that the telescopic portion 321 also shrinks or expands, and drives the blocking member 200 to close at least part of the air duct 120 through the connecting portion 322. Thereby reducing the amount of airflow entering the accommodating chamber 110 and reducing the amount of cold air in the accommodating chamber 110. Preventing the food in the accommodating chamber 110 from being frozen by the low-temperature and high-flow airflow. The freshness of the food is ensured and the reliability of the refrigerator 10 is improved.

[0042] It should be noted that the telescopic portion 321 and the connecting portion 322 can be manufactured in one piece or can be manufactured separately and then assembled.

[0043] It should be noted that when the air flow temperature of the air duct 120 is lower than the preset temperature, the air flow blows to the airbag 310 , and the airbag 310 may shrink or expand, so as to drive the stopper 200 to close at least part of the air duct 120 .

[0044] like Figure 3 As shown, in some embodiments, when the air flow temperature of the air duct 120 is lower than a preset temperature, the volume of the gas in the airbag 310 shrinks to shrink the telescopic portion 321. The telescopic portion 321 pulls the stopper 200 through the connecting portion 322.

[0045] like Figure 3 As shown, in some embodiments, the telescopic portion 321 and the blocking member 200 are respectively arranged on both sides of the air duct 120, so that when the telescopic portion 321 contracts, the blocking member 200 can be pulled to move in a direction close to the air duct 120. In this way, when the air flow temperature of the air duct 120 is lower than the preset temperature, and at least part of the airbag 310 is located in the air duct 120, the volume of the gas in the airbag 310 contracts, driving the contraction portion to contract. The telescopic portion 321 and the blocking member 200 are respectively arranged on both sides of the air duct 120, and when the telescopic portion 321 contracts, the blocking member 200 is pulled to move in a direction close to the telescopic portion 321, that is, the blocking member 200 moves in a direction close to the air duct 120, thereby closing at least part of the air duct 120, thereby reducing the amount of airflow entering the accommodating chamber 110, and reducing the amount of cold air in the accommodating chamber 110. Prevent the food in the accommodating chamber 110 from being frozen by the low-temperature and high-flow airflow.

[0046] It can be understood that the telescopic portion 321 and the blocking member 200 are respectively disposed on opposite sides of the air duct 120 , that is, the telescopic portion 321 and the blocking member 200 are disposed opposite to each other, and the air duct 120 is located between the telescopic portion 321 and the blocking member 200 .

[0047] like Figure 4 As shown, in other embodiments, when the air flow temperature of the air duct 120 is lower than a preset temperature, the volume of the gas in the airbag 310 expands to expand the telescopic portion 321. The telescopic portion 321 pushes the stopper 200 through the connecting portion 322.

[0048] like Figure 4As shown, in some embodiments, the telescopic portion 321 and the baffle 200 are arranged on the same side of the air duct 120, and the baffle 200 is arranged close to the air duct 120 relative to the telescopic portion 321, so that when the telescopic portion 321 expands, it can push the baffle 200 to move in the direction close to the air duct 120. In this way, when the air flow temperature of the air duct 120 is lower than the preset temperature, and at least part of the airbag 310 is located in the air duct 120, the volume of the gas in the airbag 310 expands, driving the contraction portion to expand. The telescopic portion 321 and the baffle 200 are arranged on the same side of the air duct 120, and the baffle 200 is arranged close to the air duct 120 relative to the telescopic portion 321, so that when the telescopic portion 321 expands, it pushes the baffle 200 to move in the direction away from the telescopic portion 321, that is, the baffle 200 moves in the direction close to the air duct 120, thereby closing at least part of the air duct 120, thereby reducing the amount of airflow entering the accommodating cavity 110 and reducing the amount of cold air in the accommodating cavity 110. The food in the accommodating chamber 110 is prevented from freezing due to the low-temperature and high-flow airflow.

[0049] like Figure 5 As shown, in some embodiments, the refrigerator 10 further includes a telescopic member 400, which is disposed around the inner wall of the air duct 120. When the air flow temperature of the air duct 120 is lower than a preset temperature, the telescopic member 400 can be retracted to close at least a portion of the air duct 120. In this way, when the air flow temperature of the air duct 120 is lower than a preset temperature, the telescopic member 400 disposed on the inner wall of the air duct 120 is cooled and the air flow is stopped. Figure 3 The contraction in the X direction shown enables the telescopic member 400 to close at least a portion of the air duct 120 , thereby reducing the amount of airflow entering the accommodating cavity 110 and reducing the amount of cold air in the accommodating cavity 110 .

[0050] It should be noted that the telescopic member 400 may be made of a material with a relatively large thermal expansion coefficient, such as polyimide, aluminum, magnesium, and the like.

[0051] like Figure 5 As shown, in some embodiments, the refrigerator 10 further includes an elastic member 500, which is disposed around the inner wall of the air duct 120, and the elastic member 500 is fixedly connected to the inner wall of the air duct 120, and the elastic member 500 is fixedly connected to the telescopic member 400. In this way, the elastic member 500 is disposed around the inner wall of the air duct 120, and when the air flow temperature of the air duct 120 is lower than a preset temperature, the telescopic member 400 will shrink, and the elastic member 500 can play a sealing role when the telescopic member 400 shrinks, thereby preventing air flow from blowing into the accommodating cavity 110 from other positions.

[0052] like Figure 5As shown, in some embodiments, the elastic member 500 is sandwiched between the inner wall of the air duct 120 and the telescopic member 400. In this way, by sandwiching the elastic member 500 between the inner wall of the air duct 120 and the telescopic member 400, the sealing effect of the elastic member 500 when the telescopic member 400 is contracted can be further improved.

[0053] It should be noted that there may be many specific implementations of the elastic member 500, including but not limited to rubber, etc., as long as it can play a sealing role when the telescopic member 400 contracts.

[0054] The components included in the "component", "device" and "equipment" disclosed in the present invention can also be flexibly combined, that is, modular production can be carried out according to actual conditions and modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in the present device.

[0055] The division of the above components in the present disclosure is only one of the embodiments, for the convenience of reading, rather than limiting the scope of protection of the present disclosure. As long as the above components are included and have the same functions, they should be understood as equivalent technical solutions of the present disclosure. In the description of the present disclosure, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present disclosure.

[0056] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0057] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0058] In the present disclosure, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0059] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixedly arranged on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-fitting, integral molding fixation, welding, etc., which can be achieved in traditional technologies and will not be repeated here.

[0060] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the utility model concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
