Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] A refrigerator is a common household appliance that can keep food or other items at a constant low temperature. The refrigerator includes a box body and a drawer disposed in the box body, and the drawer forms a storage space in a negative pressure state, so as to store food in the storage space in a negative pressure state.

[0003] When food needs to be put into the drawer or taken out of the drawer, a pressure relief device is usually used to relieve pressure on the drawer so that air outside the drawer can enter the receiving space in a negative pressure state. However, the pressure relief device used for the pressure relief process of the drawer receiving space has a single function. Utility Model Content

[0004] The embodiment of the present application provides a refrigerator, which can solve the technical problem of the single function of the pressure relief device used in the pressure relief process of the drawer accommodating space.

[0005] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0006] A box body, wherein the box body defines a mounting cavity having an opening on one side;

[0007] A drawer is movably arranged in the installation cavity; when the drawer is in a locked state, the drawer is located in the installation cavity, the drawer forms a storage space in a negative pressure state, and the storage space has an opening communicating with the outside of the drawer; when the drawer is in a pressure relief state, the drawer is movable relative to the box body;

[0008] The pressure relief device comprises a sealing member and a control member connected to each other, wherein the sealing member is movably arranged at the opening; when the drawer is in the locked state, the control member drives the sealing member to close the opening; when the drawer is switched from the locked state to the pressure relief state, the control member drives the sealing member to separate from the opening;

[0009] A functional element, wherein the control end of the functional element is connected to the control component, and the control component is used to control the opening or closing of the functional element.

[0010] In the refrigerator of the embodiment of the present application, when the drawer is in a locked state, the drawer is located in the installation cavity, and the drawer forms a storage space in a negative pressure state, so that food can be stored in the storage space in a negative pressure state. The storage space has an opening connected to the outside of the drawer, and the sealing member blocks the opening to ensure the sealing of the storage space, and the outside of the drawer is not connected to the storage space.

[0011] When the storage space of the drawer is depressurized, the seal can be driven to detach from the opening through the control member to allow air outside the drawer to enter the storage space, and the drawer is converted from a locking state to a depressurization state, thereby realizing the depressurization process of the drawer. The depressurization process of the drawer is more convenient, so that the drawer can be movable relative to the box body, and the storage space of the drawer can be exposed, so as to realize the taking and placing of food in the storage space.

[0012] Furthermore, when the drawer's storage space is depressurized, the control component can also control the functional element through the control end of the functional element to open or close the functional element, thereby realizing other functions of the drawer through the functional element, so that the pressure relief device can not only be used to realize the pressure relief process of the drawer's storage space, but also control the opening or closing of the functional element, thereby enriching the function of the pressure relief device.

[0013] In some embodiments of the present application, the pressure relief device further includes a base, the control member is movably disposed on the base, and the control member has a first position and a second position;

[0014] When the control member is in the first position, the control member controls the sealing member to close the opening; when the control member moves from the first position toward the second position, the control member drives the sealing member to separate from the opening.

[0015] In this arrangement, when the control member is in the first position, the control member controls the sealing member to close the opening; when the control member moves from the first position toward the second position, the control member drives the sealing member to separate from the opening. When the drawer storage space is depressurized, the position of the control member can be adjusted so that the control member can move from the first position toward the second position, so that the sealing member is driven by the control member to gradually separate from the opening of the storage space, thereby achieving the depressurization process of the drawer.

[0016] When it is necessary to form a negative pressure state in the accommodating space, the position of the control member can be adjusted so that the control member can move from the second position to the first position. The control member drives the sealing member to close the opening, thereby making the accommodating space airtight, so that a negative pressure state can be formed in the accommodating space through a vacuum device, etc.

[0017] In some embodiments of the present application, the functional element includes a reminder, and the reminder is at least configured as:

[0018] In the process of the control member driving the sealing member to separate from the opening, when the control member is in the second position, the reminder member is used to indicate that the drawer is in the pressure relief state; when the control member is not in the second position, the reminder member is used to indicate that the drawer is not in the pressure relief state.

[0019] In this way, when the control member drives the sealing member to disengage from the opening, when the control member is in the second position, the sealing member completely disengages from the opening, so that the accommodating space is connected with the outside of the drawer through the opening, and the reminder member can be used to indicate that the drawer is in a pressure relief state, thereby allowing the user to more conveniently and quickly determine the state of the drawer completing pressure relief through the reminder member.

[0020] During the process of the control member driving the sealing member to disengage from the opening, when the control member is not in the second position, the reminder member is used to indicate that the drawer is not in a pressure relief state, the accommodating space is still in a negative pressure state, and there is a binding force between the drawer and the box body. The reminder member can be used to remind the user not to pull the drawer, so as to avoid the possibility of deformation or damage caused by excessive force between the drawer and the box body, thereby extending the service life of the drawer.

[0021] In some embodiments of the present application, the functional element includes a reminder and a pressure sensing element, and the pressure sensing element is connected to the control end of the reminder; the reminder is configured as follows:

[0022] When the control element is in the first position and the pressure sensing element obtains that the accommodating space is in a negative pressure state, the reminder element is used to indicate that the drawer is in the locked state;

[0023] When the control element is in the second position, the reminder element is used to indicate that the drawer is in the pressure relief state;

[0024] When the control element is between the first position and the second position and the pressure sensing element obtains that the accommodating space is in a negative pressure state, the reminder element is used to indicate that the drawer is not in the pressure relief state;

[0025] When the control member is between the first position and the second position and the pressure sensing member obtains that the accommodating space is not in a negative pressure state, the reminder member is used to indicate that the drawer is in the pressure relief state.

[0026] In this way, when the control element is in the first position and the pressure sensing element obtains that the accommodating space is in a negative pressure state, the reminder element is used to indicate that the drawer is in a locked state, so as to remind the user not to open the drawer at this time. When the control element is in the second position, the reminder element is used to indicate that the drawer is in a pressure relief state, so as to remind the user that the drawer can be opened at this time.

[0027] During the process of the control member driving the sealing member to separate from the opening, the control member is between the first position and the second position, and the pressure sensing member obtains that the accommodating space is not in a negative pressure state, so that the accommodating space can be connected with the outside of the drawer through the opening, and the reminder member can be used to indicate that the drawer is in a pressure relief state, so that the user can more conveniently and quickly determine the state of the drawer completing pressure relief through the reminder member.

[0028] In the process of the control member driving the sealing member to disengage from the opening, when the control member is between the first position and the second position, and the pressure sensing member obtains that the accommodating space is not in a negative pressure state, the reminder member is used to indicate that the drawer is not in a pressure relief state, and the accommodating space is still in a negative pressure state. There is a binding force between the drawer and the box body, and the reminder member can be used to remind the user not to pull the drawer, so as to avoid the possibility of deformation or damage caused by excessive force between the drawer and the box body, thereby extending the service life of the drawer.

[0029] In some embodiments of the present application, the functional element includes a ventilation component, which is disposed in the accommodating space and is configured as follows:

[0030] When the control element is in the first position, the ventilation element is not in a working state;

[0031] When the control member is not in the first position, the ventilation member is in a working state, and the ventilation member is at least used to drive air to flow outside the drawer and in the accommodating space.

[0032] With such arrangement, when the control element is in the first position, the drawer is in a locked state, the accommodating space is in a negative pressure state, and the ventilation element is not in a working state, so there is no need to ventilate the accommodating space through the ventilation element.

[0033] When the control member is not in the first position, the control member drives the sealing member to disengage from the opening, the storage space can be connected with the outside of the drawer through the opening, the ventilation member can be in a working state, and the ventilation member is at least used to drive air to flow outside the drawer and in the storage space, thereby speeding up the flow of air in the storage space and reducing the possibility of food in the storage space generating odor.

[0034] In some embodiments of the present application, the functional element includes a ventilation element and a position sensor, the position sensor is used to obtain the position of the accommodating space and the box, the position sensor is connected to the control end of the ventilation element, and the ventilation element is configured as follows:

[0035] When the control element is not in the first position and the position sensor obtains that the accommodation space is facing the box body, the ventilation element is not in a working state;

[0036] When the control member is not in the first position and the position sensor obtains that at least a portion of the accommodating space is not facing the box body, the ventilator is in a working state, and the ventilator is connected to the outside of the drawer through the accommodating space.

[0037] In this arrangement, when the control member is in the first position and the position sensor obtains that the storage space is facing the box body, the drawer is in a locked state, the storage space is in a negative pressure state, and the ventilation member may not be in a working state, so there is no need to ventilate the storage space through the ventilation member.

[0038] When the control component is not in the first position and at least part of the storage space obtained by the position sensor is not facing the box body, the control component drives the sealing component to separate from the opening, and the storage space can be connected with the outside of the drawer through the opening and the top, and the ventilation component can be in a working state. The ventilation component is at least used to drive air to flow outside the drawer and in the storage space, thereby speeding up the flow of air in the storage space and reducing the possibility of food in the storage space generating odor.

[0039] In some embodiments of the present application, the pressure relief device further includes a transmission structure, an input end of the transmission structure is connected to the control element, and an output end of the transmission structure is connected to the sealing element.

[0040] With such an arrangement, when the position of the seal needs to be adjusted so as to drive the seal to move relative to the opening through the control member, the control member is moved so that the control member can drive the seal to close or open the opening through the transmission structure, thereby connecting the control member and the seal through the transmission structure, making the movement of the seal more convenient.

[0041] In some embodiments of the present application, the transmission structure includes a first connecting rod and a second connecting rod, and the first end of the first connecting rod is rotatably disposed on the drawer;

[0042] The middle portion of the second connecting rod is connected to the second end of the first connecting rod, the first end of the second connecting rod is connected to the control member, and the second end of the second connecting rod is connected to the sealing member;

[0043] The distance between the first end of the second connecting rod and the first end of the first connecting rod is greater than the distance between the second end of the second connecting rod and the first end of the first connecting rod.

[0044] With such arrangement, when the position of the sealing member needs to be adjusted so as to drive the sealing member to move relative to the opening through the control member, the control member is moved so that the control member can drive the sealing member to block or open the opening through the transmission structure.

[0045] The control member can drive the first connecting rod to rotate relative to the drawer through the second connecting rod, so that the control member can drive the sealing member to move through the connected first connecting rod and the second connecting rod, so that the control member and the sealing member can be connected through the transmission structure, and the distance between the first end of the second connecting rod and the first end of the first connecting rod is greater than the distance between the second end of the second connecting rod and the first end of the first connecting rod. The transmission structure can form a labor-saving lever structure, so that the movement of the sealing member is more labor-saving and convenient.

[0046] In some embodiments of the present application, the pressure relief device includes an elastic member, a first end of the elastic member is connected to the base, a second end of the elastic member is connected to the control member, and the elastic member is at least used to drive the control member to move toward the first position.

[0047] With such a configuration, when the position of the seal needs to be adjusted so as to drive the seal to move relative to the opening through the control member, the control member is moved so that the control member moves from the first position toward the second position, the elastic member is deformed, and the control member drives the seal to separate from the opening, thereby realizing the pressure relief process of the drawer accommodating space.

[0048] When the pressure relief process of the drawer storage space is completed, the elastic member can be reset, and the elastic member drives the control member to move from the second position toward the first position, so that the control member drives the sealing member to close the opening, so as to reduce the possibility that the sealing member is not reset, so that the storage space cannot be sealed, and the preservation effect of the food is affected.

[0049] In a second aspect, an embodiment of the present application provides a refrigerator, including a box body, a drawer, a pressure relief device and a functional element;

[0050] The drawer is movably arranged in the installation cavity of the box body; when the drawer is in a locked state, the drawer is located in the installation cavity, and the drawer forms a storage space in a negative pressure state, and the storage space has an opening communicating with the outside of the drawer; when the drawer is in a pressure relief state, the drawer is movable relative to the box body;

[0081] As described in the background art, in the related art, a refrigerator includes a box body and a drawer disposed in the box body, and the drawer forms a storage space in a negative pressure state, so as to store food in the storage space in a negative pressure state. When food needs to be put into the drawer or taken out of the drawer, it is usually necessary to use a pressure relief device to relieve the pressure of the drawer so that the air outside the drawer can enter the storage space in a negative pressure state.

[0082] However, when using the pressure relief device to achieve the pressure relief process of the drawer, it is usually necessary to remove the seal from the opening of the drawer so that the storage space of the drawer can be connected to the outside of the drawer. When the pressure relief of the drawer is completed, the seal needs to be reinstalled on the opening of the drawer to achieve the re-sealing of the drawer storage space. In addition, since the pressure relief device can usually only be used to achieve the pressure relief process of the drawer, the function of the pressure relief device is single.

[0083] In view of this, in the refrigerator of the embodiment of the present application, when the drawer is in a locked state, the drawer is located in the installation cavity, and the drawer forms a storage space in a negative pressure state, so that food can be stored in the storage space in a negative pressure state. The storage space has an opening connected to the outside of the drawer, and the sealing member blocks the opening to ensure the sealing of the storage space, and the outside of the drawer is not connected to the storage space.

[0084] When the storage space of the drawer is depressurized, the seal can be driven to detach from the opening through the control member to allow air outside the drawer to enter the storage space, and the drawer is converted from a locking state to a depressurization state, thereby realizing the depressurization process of the drawer. The depressurization process of the drawer is more convenient, so that the drawer can be movable relative to the box body, and the storage space of the drawer can be exposed, so as to realize the taking and placing of food in the storage space.

[0085] Furthermore, when the drawer's storage space is depressurized, the control component can also control the functional element through the control end of the functional element to open or close the functional element, thereby realizing other functions of the drawer through the functional element, so that the pressure relief device can not only be used to realize the pressure relief process of the drawer's storage space, but also control the opening or closing of the functional element, thereby enriching the function of the pressure relief device.

[0086] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0092] 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.

[0093] An embodiment of the present application provides a refrigerator, including a body 100, the body 100 includes a top and a bottom arranged along the length direction, a storage compartment can be formed inside the body 100, the storage compartment can include a refrigerating compartment and a freezing compartment, so that food can be refrigerated or frozen in the storage compartment and the freezing compartment.

[0094] The refrigerator of the present application may include a door body. The door body may include a door body liner and a door body shell, and the door body may at least be used to open and close the storage space, and the door body may be used to form a relatively closed space of the cabinet 100, so that the storage compartment of the cabinet 100 can maintain a relatively constant temperature and reduce the rising speed of the storage compartment temperature.

[0095] In some possible implementations, the box body 100 defines an installation cavity 110 having a side opening 231. The installation cavity 110 may be located in a storage compartment, for example, the installation cavity 110 may be located in a refrigerator compartment, or the installation cavity 110 may also be located in a freezer compartment.

[0096] Exemplarily, the refrigerator may include a drawer 200. The drawer 200 is movably disposed in the mounting cavity 110. When the drawer 200 is in a locked state, the drawer 200 is located in the mounting cavity 110, and the drawer 200 may form a receiving space 230 in a negative pressure state, so that food to be stored can be accommodated in the receiving space 230 in a negative pressure state. When the drawer 200 is in a depressurized state, the drawer 200 is movable relative to the housing 100, so that the drawer 200 can be moved into or out of the mounting cavity 110 to achieve the taking and placing of food.

[0097] The storage space 230 has an opening 231 connected to the outside of the drawer 200. When the drawer 200 is in a locked state, the opening 231 is closed so that the storage space 230 is in a negative pressure state. When the storage space 230 of the drawer 200 is depressurized, the opening 231 is opened so that the air outside the drawer 200 enters the storage space 230, and the drawer 200 is converted from the locked state to the depressurized state, thereby realizing the depressurization process of the drawer 200.

[0098] The refrigerator may include a pressure relief device 300. The pressure relief device 300 may include a sealing member 320. The sealing member 320 may be movably disposed at the opening 231, and the sealing member 320 may close or open the opening 231 to achieve sealing and pressure relief of the accommodation space 230.

[0099] The pressure relief device 300 may include a control member 330. The control member 330 is connected to the sealing member 320, and the control member 330 may drive the sealing member 320 to move relative to the drawer 200. When the drawer 200 is in a locked state, the control member 330 may drive the sealing member 320 to close the opening 231. When the drawer 200 is switched from the locked state to the pressure relief state, the control member 330 may drive the sealing member 320 to disengage from the opening 231.

[0100] When the drawer 200 is in a locked state, the drawer 200 is located in the installation cavity 110, and the drawer 200 forms a receiving space 230 in a negative pressure state, so that food can be received in the receiving space 230 in a negative pressure state. The receiving space 230 has an opening 231 connected to the outside of the drawer 200, and the sealing member 320 blocks the opening 231, thereby ensuring the sealing of the receiving space 230, and the outside of the drawer 200 is not connected to the receiving space 230.

[0101] When the storage space 230 of the drawer 200 is depressurized, the seal 320 can be driven to disengage from the opening 231 through the control member 330 to allow the air outside the drawer 200 to enter the storage space 230. The drawer 200 is converted from a locked state to a depressurized state, thereby realizing the depressurization process of the drawer 200. The depressurization process of the drawer 200 is more convenient, so that the drawer 200 can be movable relative to the box body 100, so that the storage space 230 of the drawer 200 can be exposed, so as to realize the taking and placing of food in the storage space 230.

[0102] For example, the refrigerator may include a functional element 400. The control end of the functional element 400 may be connected to the control element 330, and the control element 330 is multiplexed to control the opening or closing of the functional element 400, so that the functions of the control element 330 are more abundant.

[0103] When the pressure in the storage space 230 of the drawer 200 is released, the control component 330 can also control the functional element 400 through the control end of the functional element 400, so that the functional element 400 is opened or closed, thereby realizing other functions of the drawer 200 through the functional element 400, so that the pressure relief device 300 can not only be used to realize the pressure relief process of the storage space 230 of the drawer 200, but also control the opening or closing of the functional element 400, thereby enriching the function of the pressure relief device 300.

[0104] In some possible embodiments, the refrigerator may include a refrigeration system, which can be used to supply cold air to the storage room at least. The refrigeration system includes a compressor, a condenser, an expansion valve and an evaporator. The refrigerant circulates in the components of the refrigeration system to achieve a refrigeration effect.

[0105] Exemplarily, the main flow process of the refrigerant in each component is: the refrigerant enters the condenser after passing through the compressor, enters the expansion valve after passing through the condenser, enters the evaporator after passing through the expansion valve, and flows back to the compressor after passing through the evaporator.

[0106] The compressor compresses the refrigerant gas at high temperature and high pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid phase refrigerant in the high temperature and high pressure state in the condenser into a low pressure liquid phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant or heat exchange with the material to be cooled.

[0107] In some possible implementations, the drawer 200 may include a main body 210, which may be a rectangular box structure with a top opening 231. A receiving space 230 is formed in the main body 210, and the receiving space 230 may be a cavity structure with a top opening. Food materials may be put into the receiving space 230 through the top opening 231 of the receiving space 230, or food materials in the receiving space 230 may be taken out from the top opening of the receiving space 230.

[0108] Exemplarily, the drawer 200 may include a drawer door 220. The drawer door 220 may be disposed at the front end of the main body 210, and the drawer door 220 may at least be used to push and pull the main body 210, thereby enabling the entire drawer 200 to be pulled and drawn in the installation cavity 110. When the entire drawer 200 is fully pushed into the installation cavity 110, the drawer door 220 may close the front opening 231 of the accommodating space 230, thereby forming a closed accommodating space 230.

[0109] The left and right sides of the main body 210 are provided with guide rails, which can extend in the front-to-back direction of the box body 100. A slide groove (not shown in the figure) matching with the guide rail can be arranged on the inner side wall of the installation cavity 110, so that the guide rail can slide forward and backward in the slide groove, and then the main body 210 can move forward and backward in the installation cavity 110 along the slide groove, thereby improving the stability of the drawer 200 in the installation cavity 110.

[0110] The left and right sides of the main body 210 may be provided with rollers, respectively. The rollers may be arranged at intervals at the rear end of the guide rail, and the rollers and the guide rail are located on the same straight line. The rollers may slide in the slide groove with the guide rail, the top surface of the rollers may protrude from the top surface of the guide rail, and the bottom surface of the rollers may protrude from the bottom surface of the guide rail. The rollers may roll in contact with the top and bottom surfaces of the slide groove, thereby avoiding direct contact between the guide rail and the slide groove, reducing the friction between the main body 210 and the inner wall of the installation cavity 110, and enabling the drawer 200 to be smoothly pulled and moved in the installation cavity 110.

[0111] The refrigerator may include a sealing ring 240, which may be provided at least one of the drawer 200 and the cabinet 100. When the drawer 200 is completely placed in the installation cavity 110 in the refrigerator, the sealing ring 240 can be clamped at the front port of the drawer door 220 and the installation cavity 110 of the cabinet 100, so as to seal the installation cavity 110 through the sealing ring 240, thereby achieving sealing of the accommodating space 230.

[0112] In some possible implementations, the drawer 200 may include an air extraction device, and an air extraction port of the air extraction device may be in communication with the accommodation space 230. When the drawer 200 is in a locked state, the drawer 200 is located in the installation cavity 110, and the air extraction device can extract the air in the accommodation space 230, so that the accommodation space 230 forms a negative pressure state.

[0113] The vacuum device can be set as a vacuum pump or other structure to reduce the air content in the storage space 230 through the vacuum pump. Compared with reducing the oxygen content in the storage space 230, reducing the air content in the storage space 230 can reduce the air pressure in the storage space 230, thereby placing the food in a negative pressure state, further improving the preservation effect of the food.

[0114] In some possible implementations, the pressure relief device 300 may further include a base 310, and the control member 330 may be movably disposed on the base 310. The base 310 may be disposed on the drawer door 220, or the base 310 may be disposed on the body 210, and the control member 330 may be connected to the drawer 200 through the base 310.

[0115] The control member 330 may have a first position and a second position. When the control member 330 is in the first position, the control member 330 controls the sealing member 320 to close the opening 231. When the control member 330 is in the second position, the control member 330 controls the sealing member 320 to open the opening 231. When the control member 330 moves from the first position to the second position, the control member 330 drives the sealing member 320 to separate from the opening 231.

[0116] Exemplarily, when the pressure in the storage space 230 of the drawer 200 is released, the position of the control member 330 can be adjusted so that the control member 330 can move from the first position toward the second position, so that the sealing member 320 gradually separates from the opening 231 of the storage space 230 under the drive of the control member 330, and the storage space 230 is connected with the outside of the drawer 200 through the opening 231, thereby realizing the pressure relief process of the drawer 200.

[0117] When it is necessary to form a negative pressure state in the accommodating space 230, the position of the control member 330 can be adjusted so that the control member 330 can move from the second position to the first position. The control member 330 drives the sealing member 320 to close the opening 231, thereby making the accommodating space 230 airtight, so that a negative pressure state can be formed in the accommodating space 230 by a vacuum device, etc.

[0118] In some embodiments of the present application, the pressure relief device 300 may further include a transmission structure 340. The input end of the transmission structure 340 may be connected to the control member 330, and the output end of the transmission structure 340 may be connected to the sealing member 320. The control member 330 may drive the sealing member 320 to close or open the opening 231 through the transmission structure 340, so that the process of the control member 330 driving the sealing member 320 is more convenient.

[0119] When the position of the seal 320 needs to be adjusted so as to drive the seal 320 to move relative to the opening 231 through the control member 330, the control member 330 is moved so that the control member 330 can drive the seal 320 to block or open the opening 231 through the transmission structure 340, thereby connecting the control member 330 and the seal 320 through the transmission structure 340, making the movement of the seal 320 more convenient.

[0120] In some embodiments of the present application, the transmission structure 340 includes a first connecting rod 341 and a second connecting rod 342. The first end of the first connecting rod 341 can be rotatably disposed on the drawer 200. The middle portion of the second connecting rod 342 can be connected to the second end of the first connecting rod 341, the first end of the second connecting rod 342 can be connected to the control member 330, and the second end of the second connecting rod 342 is connected to the sealing member 320.

[0121] When the position of the sealing member 320 needs to be adjusted so as to drive the sealing member 320 to move relative to the opening 231 through the control member 330 , the control member 330 is moved so that the control member 330 can drive the sealing member 320 to block or open the opening 231 through the transmission structure 340 .

[0122] The transmission structure 340 can be set as a force-saving lever structure. For example, the distance between the first end of the second connecting rod 342 and the first end of the first connecting rod 341 is greater than the distance between the second end of the second connecting rod 342 and the first end of the first connecting rod 341 .

[0123] The control member 330 can drive the first link 341 to rotate relative to the drawer 200 through the second link 342, so that the control member 330 can drive the seal 320 to move through the connected first link 341 and the second link 342, so that the control member 330 and the seal 320 can be connected through the transmission structure 340, and the distance between the first end of the second link 342 and the first end of the first link 341 is greater than the distance between the second end of the second link 342 and the first end of the first link 341. The transmission structure 340 can form a labor-saving lever structure, so that the movement of the seal 320 is more labor-saving and convenient.

[0124] Exemplarily, the second end of the second connecting rod 342 may be provided with a connecting portion 343. One end of the connecting portion 343 away from the second connecting rod 342 may extend toward the drawer door 220, and one end of the connecting portion 343 away from the second connecting rod 342 may be connected to the sealing member 320, so that the sealing member 320 can be connected to the second connecting rod 342 through the connecting portion 343, thereby increasing the distance between the second end of the second connecting rod 342 and the drawer door 220, and reducing the possibility of the second connecting rod 342 being interfered by the drawer door 220 during the rotation process.

[0125] The connection direction of the sealing member 320 and the rotation axis of the transmission structure 340 can be set parallel to the extension direction of the second connecting rod 342. When the control button 330 drives the sealing member 320 to leave the opening 231 through the transmission structure 340, the movement direction of the control button 330 is set parallel to the movement direction of the sealing member 320.

[0126] By adopting the above technical solution, when the control button 330 drives the seal 320 to detach from the opening 231 through the transmission structure 340, the moving direction of the control button 330 and the moving direction of the seal 320 can be set parallel, so that the seal 320 is easier to detach from the opening 231, thereby making the movement process of the seal 320 more convenient.

[0127] A reinforcement member 344 may be provided between the rotation axis and the second end of the second connecting rod 342. The first end of the reinforcement member 344 may rotate around the rotation axis, and the second end of the reinforcement member 344 may be fixedly connected to the second end of the second connecting rod 342. The reinforcement member 344, the first connecting rod 341, the second connecting rod 342 second end and the portion of the second connecting rod 342 between the connection point together form a triangle, so that the structure of the transmission structure 340 is more stable.

[0128] The reinforcement member 344 and the second connecting rod 342 can be relatively fixedly connected. For example, the reinforcement member 344 and the second connecting rod 342 can be connected by plugging or threading, so that the reinforcement member 344 and the second connecting rod 342 can be formed separately, and the connection position of the reinforcement member 344 and the second connecting rod 342 is more flexible to adapt to different usage modes.

[0129] Alternatively, the reinforcement member 344 and the second connecting rod 342 may be integrally provided to facilitate the molding process of the reinforcement member 344 and the second connecting rod 342. Moreover, compared with the spliced ​​reinforcement member 344 and the second connecting rod 342, the connection structure of the integrally formed reinforcement member 344 and the second connecting rod 342 is more stable, the connection position of the reinforcement member 344 and the second connecting rod 342 does not need to be positioned, and the installation process of the reinforcement member 344 and the second connecting rod 342 is also more convenient.

[0130] Alternatively, the reinforcement 344 can also be integrally provided with the connecting portion 343, so that the reinforcement 344 and the connecting portion 343 can be integrally installed on the second end of the second connecting rod 342, and the reinforcement 344 is installed on the rotating shaft, thereby making the installation of the reinforcement 344 and the connecting portion 343 more convenient.

[0131] Since the connecting portion 343, the first connecting rod 341 and the second connecting rod 342 are fixedly connected, and the seal 320 is fixedly connected to the connecting portion 343, the moving direction of the seal 320 is approximately perpendicular to the direction of the line connecting the seal 320 and the rotating axis of the transmission structure 340. By setting the direction of the line connecting the opening 231 and the rotating axis of the transmission structure 340 perpendicular to the direction of the opening 231, when the seal 320 begins to close or disengage from the opening 231, the moving direction of the seal 320 can be approximately parallel to the direction of the opening 231.

[0132] It should be noted that when it is necessary to move the control member 330 from the first position toward the second position so that the control member 330 drives the seal 320 to gradually separate from the opening 231, since the accommodating space 230 is in a negative pressure state, the accommodating space 230 will produce a certain adsorption force on the seal 320, so that the process of the seal 320 separating from the opening 231 is subject to a certain resistance. By setting the transmission structure 340 as a labor-saving lever structure, the process of the control member 330 driving the seal 320 to separate from the opening 231 can be made more labor-saving, and the control member 330 can be moved more easily from the first position to the second position, making the pressure relief process of the drawer 200 more convenient.

[0133] In some embodiments of the present application, the pressure relief device 300 may include an elastic member. A first end of the elastic member may be connected to the base 310, and a second end of the elastic member may be connected to the control member 330. The elastic member is at least used to drive the control member 330 to move toward the first position.

[0134] When the position of the seal 320 needs to be adjusted so as to drive the seal 320 to move relative to the opening 231 through the control member 330, the control member 330 is moved so that the control member 330 moves from the first position toward the second position, the elastic member is deformed, and the control member 330 drives the seal 320 to disengage from the opening 231, thereby realizing the pressure relief process of the drawer 200 accommodating space 230.

[0135] When the pressure relief process of the drawer 200 storage space 230 is completed, the elastic member can be reset, and the elastic member drives the control member 330 to move from the second position toward the first position, so that the control member 330 drives the sealing member 320 to close the opening 231, so as to reduce the possibility that the sealing member 320 is not reset, so that the storage space 230 cannot be sealed, thereby affecting the preservation effect of the food.

[0136] In some possible implementations, the functional element 400 includes a reminder 410. The reminder 410 may be configured as at least:

[0137] When the control member 330 drives the sealing member 320 to separate from the opening 231 and the control member 330 is in the second position, the reminder member 410 is used to indicate that the drawer 200 is in a pressure relief state and the accommodating space 230 is connected with the outside of the drawer 200 through the opening 231 .

[0138] During the process of the control member 330 driving the sealing member 320 to disengage from the opening 231, when the control member 330 is in the second position, the sealing member 320 completely disengages from the opening 231, so that the accommodating space 230 is connected with the outside of the drawer 200 through the opening 231, and the reminder member 410 can be used to indicate that the drawer 200 is in a pressure relief state, so that the user can more conveniently and quickly determine the state of the drawer 200 completing pressure relief through the reminder member 410.

[0139] When the control member 330 drives the sealing member 320 to separate from the opening 231 and the control member 330 is not in the second position, the reminder member 410 is used to indicate that the drawer 200 is not in a pressure relief state and the air pressure in the accommodating space 230 is less than the atmospheric pressure.

[0140] In the process of the control member 330 driving the sealing member 320 to disengage from the opening 231, when the control member 330 is not in the second position, the reminder member 410 is used to indicate that the drawer 200 is not in a pressure relief state, the accommodating space 230 is still in a negative pressure state, and there is a binding force between the drawer 200 and the box body 100. The reminder member 410 can be used to remind the user not to pull the drawer 200, so as to avoid the possibility of deformation or damage due to excessive force between the drawer 200 and the box body 100, thereby extending the service life of the drawer 200.

[0141] The control end of the reminder member 410 may be closer to the second position relative to the first position. When the control member 330 is in the second position, the control member 330 contacts the control end of the reminder member 410, so that the reminder member 410 can indicate that the drawer 200 is in a pressure relief state. When the control member 330 is not in the second position, the control member 330 does not contact the control end of the reminder member 410, so that the reminder member 410 can indicate that the drawer 200 is not in a pressure relief state.

[0142] It should be noted that when the drawer 200 is completely placed in the installation cavity 110 in the refrigerator, the sealing ring 240 can be clamped at the front port of the drawer door 220 and the installation cavity 110 of the cabinet 100, so as to seal the installation cavity 110 through the sealing ring 240. When the accommodating space 230 is in a negative pressure state, there is a squeezing and bonding force between the end face of the sealing ring 240 and the cabinet 100. When the user pulls the drawer 200, there is a bonding force and a pulling force between the end face of the sealing ring 240 and the cabinet 100, which is opposite to the bonding force between the sealing ring 240 and the drawer 200, so that the sealing ring 240 may be separated from the drawer 200, or part of the sealing ring 240 may be subjected to uneven force, so that the sealing ring 240 may also be deformed or damaged.

[0143] In some possible implementations, the functional element 400 may include a reminder 410 and a pressure sensing element 411. The pressure sensing element 411 may be connected to a control end of the reminder 410. The reminder 410 is configured as follows:

[0144] When the control member 330 is in the first position and the pressure sensing member 411 detects that the accommodation space 230 is in a negative pressure state, the reminder member 410 is used to indicate that the drawer 200 is in a locked state. When the control member 330 is in the second position, the reminder member 410 is used to indicate that the drawer 200 is in a pressure relief state.

[0145] When the control member 330 is between the first position and the second position, and the pressure sensing member 411 obtains that the accommodating space 230 is in a negative pressure state, the reminder member 410 is used to indicate that the drawer 200 is not in a pressure relief state. When the control member 330 is between the first position and the second position, and the pressure sensing member 411 obtains that the accommodating space 230 is not in a negative pressure state, the reminder member 410 is used to indicate that the drawer 200 is in a pressure relief state.

[0146] By adopting the above technical solution, when the control member 330 is in the first position and the pressure sensing member 411 obtains that the accommodating space 230 is in a negative pressure state, the reminder member 410 is used to indicate that the drawer 200 is in a locked state, so as to remind the user not to open the drawer 200 at this time. When the control member 330 is in the second position, the reminder member 410 is used to indicate that the drawer 200 is in a pressure relief state, so as to remind the user that the drawer 200 can be opened at this time.

[0147] When the control member 330 drives the sealing member 320 to disengage from the opening 231, the control member 330 is between the first position and the second position, and the pressure sensing member 411 obtains that the accommodating space 230 is not in a negative pressure state, so that the accommodating space 230 can be connected with the outside of the drawer 200 through the opening 231. The reminder member 410 can be used to indicate that the drawer 200 is in a pressure relief state, so that the user can more conveniently and quickly determine the state of the drawer 200 completing pressure relief through the reminder member 410.

[0148] In the process of the control member 330 driving the sealing member 320 to disengage from the opening 231, when the control member 330 is between the first position and the second position, and the pressure sensing member 411 obtains that the accommodating space 230 is not in a negative pressure state, the reminder member 410 is used to indicate that the drawer 200 is not in a pressure relief state, and the accommodating space 230 is still in a negative pressure state. There is a binding force between the drawer 200 and the box body 100. The reminder member 410 can be used to remind the user not to pull the drawer 200, so as to avoid the possibility of deformation or damage due to excessive force between the drawer 200 and the box body 100, thereby extending the service life of the drawer 200.

[0149] The control end of the reminder member 410 may be closer to the second position relative to the first position. When the control member 330 is in the second position, the control member 330 contacts the control end of the reminder member 410, so that the reminder member 410 can indicate that the drawer 200 is in a depressurized state.

[0150] When the control member 330 is not in the second position, the control member 330 is not in contact with the control end of the reminder member 410, and when the pressure sensing member 411 obtains that the accommodating space 230 is in a negative pressure state, the pressure sensing member 411 and the control member 330 jointly control the reminder member 410 so that the reminder member 410 can indicate that the drawer 200 is not in a pressure relief state.

[0151] When the control member 330 is not in the second position, the control member 330 is not in contact with the control end of the reminder member 410, and the pressure sensing member 411 obtains that the accommodating space 230 is not in a negative pressure state, the pressure sensing member 411 and the control member 330 jointly control the reminder member 410 so that the reminder member 410 can indicate that the drawer 200 is in a pressure relief state.

[0152] It is easy to understand that when the pressure of the receiving space 230 of the drawer 200 is released, the control member 330 can drive the sealing member 320 to separate from the opening 231, so that the air outside the drawer 200 enters the receiving space 230, and the drawer 200 is converted from the locked state to the pressure relief state, thereby realizing the pressure relief process of the drawer 200. In addition, the reminder member 410 and the pressure sensing member 411 cooperate with each other to detect the air pressure in the receiving space 230, and remind the user through the reminder member 410, thereby reducing the possibility of damage to the drawer 200 and the sealing ring 240.

[0153] In some possible implementations, the functional element 400 may include a ventilation element 420. The ventilation element 420 is disposed in the accommodation space 230. The ventilation element 420 may be used to speed up the flow of air in the accommodation space 230. The ventilation element 420 may be configured as follows:

[0154] Exemplarily, when the control member 330 is in the first position, the ventilator 420 is not in operation. When the control member 330 is not in the first position, the ventilator 420 is in operation, and the ventilator 420 is at least used to drive air to flow outside the drawer 200 and the accommodating space 230.

[0155] It should be noted that the ventilation component 420 is arranged in the accommodating space 230, which can be used to refer to that the ventilation component 420 is arranged in the accommodating space 230 as a whole, or it can also be used to refer to that part of the ventilation component 420 is arranged in the accommodating space 230, so as to speed up the flow rate of air in the accommodating space 230.

[0156] By adopting the above technical solution, when the control member 330 is in the first position, the drawer 200 is in a locked state, the storage space 230 is in a negative pressure state, and the ventilation member 420 is not in a working state, so there is no need to ventilate the storage space 230 through the ventilation member 420.

[0157] When the control member 330 is not in the first position, the control member 330 drives the sealing member 320 to disengage from the opening 231, and the storage space 230 can be connected with the outside of the drawer 200 through the opening 231. The ventilation member 420 can be in a working state. The ventilation member 420 is at least used to drive the air to flow outside the drawer 200 and the storage space 230, thereby speeding up the flow of air in the storage space 230 and reducing the possibility of food in the storage space 230 generating odor.

[0158] It should be noted that when food is stored in the storage space 230 for a long time, the storage space 230 is in a negative pressure state, which makes it easy for the food to adhere to the smell of the food, thereby affecting the storage of the food. In the process of the control member 330 driving the sealing member 320 to separate from the opening 231, although air can enter the storage space 230 through the opening 231, the air flows slowly after entering the storage space 230 due to the low flow speed of the air, making it difficult for the smell of the food in the storage space 230 to dissipate.

[0159] The control end of the ventilation member 420 may be closer to the second position relative to the first position. When the control member 330 is in the second position, the control member 330 contacts the control end of the ventilation member 420, so that the accommodation space 230 is ventilated through the ventilation member 420. When the control member 330 is not in the second position, the control member 330 does not contact the control end of the ventilation member 420, so that the ventilation member 420 does not ventilate the accommodation space 230.

[0160] By arranging a ventilation component 420 in the storage space 230, the ventilation component 420 can at least be used to drive air to flow outside the drawer 200 and in the storage space 230, thereby accelerating the flow of air in the storage space 230, accelerating the dissipation speed of the odor of the food in the storage space 230, and reducing the possibility of the food in the storage space 230 generating odor.

[0161] In some possible implementations, the functional element 400 may include a ventilation element 420 and a position sensor 421. The position sensor 421 is used to obtain the positions of the accommodating space 230 and the box 100. The position sensor 421 is connected to the control end of the ventilation element 420. The ventilation element 420 is configured as follows:

[0162] When the control member 330 is not in the first position and the position sensor 421 obtains that the accommodation space 230 is facing the box body 100, the ventilator 420 is not in the working state. When the control member 330 is not in the first position and the position sensor 421 obtains that at least part of the accommodation space 230 is not facing the box body 100, the ventilator 420 is in the working state, and the ventilator 420 is connected to the outside of the drawer 200 through the accommodation space 230.

[0163] When the control member 330 is in the second position, the control member 330 contacts the control end of the ventilation member 420, so that the accommodating space 230 is ventilated through the ventilation member 420. When the control member 330 is not in the first position, and the position sensor 421 obtains that the accommodating space 230 is facing the box body 100, the ventilation member 420 is not in the working state, and the drawer 200 is located in the installation cavity 110, so that the ventilation member 420 does not ventilate the accommodating space 230.

[0164] When the control component 330 is not in the first position and the position sensor 421 obtains that at least a portion of the storage space 230 is not facing the box body 100, the drawer 200 is located outside the installation cavity 110, and the ventilation component 420 is in a working state. The ventilation component 420 is connected to the outside of the drawer 200 through the storage space 230 to ventilate the storage space 230 through the ventilation component 420.

[0165] By adopting the above technical solution, when the control component 330 is in the first position and the position sensor 421 obtains that the storage space 230 is facing the box body 100, the drawer 200 is in a locked state, the storage space 230 is in a negative pressure state, and the ventilation component 420 may not be in a working state, so there is no need to ventilate the storage space 230 through the ventilation component 420.

[0166] When the control component 330 is not in the first position and the position sensor 421 obtains that at least a portion of the storage space 230 is not facing the box body 100, the control component 330 drives the sealing component 320 to disengage from the opening 231, and the storage space 230 can be connected with the outside of the drawer 200 through the opening 231 and the top, and the ventilation component 420 can be in a working state. The ventilation component 420 is at least used to drive air to flow outside the drawer 200 and the storage space 230, thereby accelerating the flow of air in the storage space 230 and reducing the possibility of food in the storage space 230 generating odor.

[0167] It is easy to understand that the functional element 400 may include at least one of a reminder component 410 and a ventilation component 420, and this embodiment of the present application does not further limit this.

[0168] In summary, when the drawer 200 is in the locked state, the drawer 200 is located in the installation cavity 110, and the drawer 200 forms a receiving space 230 in a negative pressure state, so that food can be accommodated in the receiving space 230 in a negative pressure state. The receiving space 230 has an opening 231 connected to the outside of the drawer 200, and the sealing member 320 blocks the opening 231, thereby ensuring the sealing of the receiving space 230, and the outside of the drawer 200 is not connected to the receiving space 230.

[0169] When the storage space 230 of the drawer 200 is depressurized, the seal 320 can be driven to disengage from the opening 231 through the control member 330 to allow the air outside the drawer 200 to enter the storage space 230. The drawer 200 is converted from a locked state to a depressurized state, thereby realizing the depressurization process of the drawer 200. The depressurization process of the drawer 200 is more convenient, so that the drawer 200 can be movable relative to the box body 100, so that the storage space 230 of the drawer 200 can be exposed, so as to realize the taking and placing of food in the storage space 230.

[0170] Furthermore, when the pressure in the storage space 230 of the drawer 200 is relieved, the control component 330 can also control the functional element 400 through the control end of the functional element 400, so that the functional element 400 is opened or closed, thereby realizing other functions of the drawer 200 through the functional element 400, so that the pressure relief device 300 can not only be used to realize the pressure relief process of the storage space 230 of the drawer 200, but also control the opening or closing of the functional element 400, thereby enriching the function of the pressure relief device 300.

[0171] The functional element 400 may include a reminder 410. When the control member 330 is in the first position and the pressure sensing member 411 obtains that the accommodating space 230 is in a negative pressure state, the reminder 410 is used to indicate that the drawer 200 is in a locked state, so as to remind the user not to open the drawer 200 at this time. When the control member 330 is in the second position, the reminder 410 is used to indicate that the drawer 200 is in a pressure relief state, so as to remind the user that the drawer 200 can be opened at this time.

[0172] When the control member 330 drives the sealing member 320 to disengage from the opening 231, the control member 330 is between the first position and the second position, and the pressure sensing member 411 obtains that the accommodating space 230 is not in a negative pressure state, so that the accommodating space 230 can be connected with the outside of the drawer 200 through the opening 231. The reminder member 410 can be used to indicate that the drawer 200 is in a pressure relief state, so that the user can more conveniently and quickly determine the state of the drawer 200 completing pressure relief through the reminder member 410.

[0173] The functional element 400 may include a ventilator 420. When the control element 330 is in the first position, the drawer 200 is locked, the receiving space 230 is in a negative pressure state, and the ventilator 420 is not in a working state, so the receiving space 230 does not need to be ventilated by the ventilator 420.

[0174] When the control member 330 is not in the first position, the control member 330 drives the sealing member 320 to disengage from the opening 231, and the storage space 230 can be connected with the outside of the drawer 200 through the opening 231. The ventilation member 420 can be in a working state. The ventilation member 420 is at least used to drive the air to flow outside the drawer 200 and the storage space 230, thereby speeding up the flow of air in the storage space 230 and reducing the possibility of food in the storage space 230 generating odor.

[0176] The drawer 200 is movably arranged in the installation cavity 110 of the box body 100; when the drawer 200 is in a locked state, the drawer 200 is located in the installation cavity 110, and the drawer 200 forms a receiving space 230 in a negative pressure state, and the receiving space 230 has an opening 231 connected to the outside of the drawer 200; when the drawer 200 is in a pressure relief state, the drawer 200 is movable relative to the box body 100;

[0177] The pressure relief device 300 includes a sealing member 320 and a control member 330 connected to each other. The sealing member 320 can be movably disposed at the opening 231. The control member 330 can at least be used to drive the sealing member 320 to close or open the opening 231.

[0178] When the accommodating space 230 of the drawer 200 is depressurized, the control member 330 drives the sealing member 320 to separate from the opening 231, so that the air outside the drawer 200 enters the accommodating space 230, and the drawer 200 is converted from the locked state to the depressurized state;

[0179] The control element 330 controls the functional element 400 through the control terminal of the functional element 400, and the functional element 400 is turned on or off.
