As shown in fig. 5, an embodiment of the present disclosure provides a refrigeration device including a door body for the refrigeration device.

The refrigerating apparatus is internally constructed with a storage space for storing articles to be refrigerated or frozen. The refrigerating device refrigerates to reduce the temperature of the internal storage space, thereby realizing the low-temperature preservation of the articles. After the refrigerating device is used for refrigerating, the temperature of the storage space is reduced, and the air pressure in the storage space is reduced. At this time, the air pressure outside the refrigerating device is larger than the air pressure difference between the outside and the inside of the air pressure refrigerating device in the storage space. This differential pressure acts on the door body for the refrigeration device. When the door body needs to be opened, the acting force is applied to the door body by the internal and external air pressure difference of the refrigerating device, so that a user can difficultly open the door body.

As shown in fig. 1 to 4, the embodiment of the present disclosure provides a door body for a refrigeration device, and the door body includes a door body 100, a handle assembly 200, an air pressure balancing seat 300, and a sealing assembly 400. The door body 100 is configured with a communication passage 110, and the inside of the refrigerating apparatus can communicate with the outside of the refrigerating apparatus through the communication passage 110. The handle assembly 200 is arranged on the door body 100, and the handle assembly 200 can rotate between a first position and a second position; the air pressure balance base 300 is connected with the handle assembly 200, and the handle assembly 200 rotates to drive the air pressure balance base 300 to rotate. The sealing assembly 400 is disposed in the communicating channel 110, and the sealing assembly 400 is connected to the air pressure balancing seat 300, and the air pressure balancing seat 300 rotates to drive the sealing assembly 400 to move along the axial direction of the communicating channel 110.

When the handle assembly 200 is in the first position, the handle assembly 200 locks the door body 100 and the seal assembly 400 seals the communication passage 110; when the handle assembly 200 is at the second position, the handle assembly 200 unlocks the door body 100, the sealing assembly 400 is reset, and the inside and the outside of the refrigeration device are communicated through the communication channel 110, so that the outside air enters the inside of the refrigeration device, and the inside and outside air pressure of the refrigeration device is balanced.

The handle assembly 200 is disposed on the door body 100, and when the handle assembly 200 is at the first position, the handle assembly 200 locks the door body 100 to prevent the door body 100 from being opened by mistake. When the handle assembly 200 rotates to the second position, the handle assembly 200 releases the locking of the door body 100, so that the door body can be smoothly opened. The air pressure balance base 300 is connected with the handle assembly 200, and the handle assembly 200 rotates to drive the air pressure balance base 300 to rotate. The door body 100 is configured with a communication channel 110, the sealing assembly 400 is arranged in the communication channel 110, and the rotation of the air pressure balancing seat 300 can drive the sealing assembly 400 to move along the axial direction of the communication channel 110. When the handle assembly 200 is in the first position, the seal assembly 400 seals the communication passage 110. That is, when the handle assembly 200 locks the door body 100, the door body 100 cannot be opened, and the inside and the outside of the refrigeration apparatus are not communicated. Therefore, the cold energy in the refrigerating device can be prevented from being dissipated to the outside, and energy loss is avoided. When the handle 201 is rotated to the second position, the sealing assembly 400 is reset, and the communication between the inside and the outside of the refrigeration device is realized. When the handle assembly 200 unlocks the door body, that is, when a user needs to open the door body, the inside and the outside of the refrigeration device are communicated through the communication channel 110 by the rotation of the handle assembly 200. The external air enters the inside of the refrigerating device through the communicating channel 110 to increase the air pressure inside the refrigerating device, so that the internal and external air pressures of the refrigerating device are balanced, and the door body can be smoothly opened.

By adopting the optional embodiment, the balance of the internal and external air pressures of the refrigerating device can be realized when the door body is opened only by normally rotating the handle assembly 200. The action of opening the door body is simple, the operation of a user is convenient, and the use experience of the user is improved.

As shown in fig. 3, in some alternative embodiments, seal assembly 400 includes a resilient seal 401 and a press block 402. The elastic seal 401 is located in the communication passage 110 with a gap between the elastic seal 401 and the inner sidewall of the communication passage 110. The press piece 402 is connected with the elastic seal 401. When the handle assembly 200 rotates to the first position, the pressing block 402 moves towards the air pressure balance seat 300, the elastic sealing element 401 is pressed between the pressing block 402 and the air pressure balance seat 300, and the elastic sealing element 401 radially extends to abut against the inner side wall of the communication channel 110 to seal the communication channel 110. When the handle assembly 200 is rotated to the second position, the pressing block 402 is moved away from the air pressure balance seat 300, the elastic sealing member 401 is reset, so that a gap is formed between the elastic sealing member 401 and the inner side wall of the communication passage 110, and the communication passage 110 communicates the inside and the outside of the refrigeration device.

With this alternative embodiment, the elastic seal 401 is located in the communication passage 110, and the elastic seal 401 has a gap between the elastic seal 401 and the inner side wall of the communication passage 110 in the initial state. When the door body 100 needs to be locked, the handle 201 rotates to the first position, and the air pressure balance seat 300 is driven to rotate. The air pressure balance seat 300 rotates to drive the pressing block 402 to move towards the air pressure balance seat 300 along the axial direction of the communication channel 110, and the elastic sealing element 401 is pressed between the pressing block 402 and the air pressure balance seat 300. The elastic seal 401 is subjected to a pressing force in the axial direction of the communication passage 110, so that the elastic seal 401 extends in the radial direction of the communication passage 110 to abut against the inner side wall of the communication passage 110, so that the elastic seal 401 seals the communication passage 110.

When it is necessary to unlock the door body 100 to open the door body 100, the handle assembly 200 is rotated to the second position. The handle assembly 200 rotates to drive the pressing block 402 to move away from the air pressure balance seat 300 along the axial direction of the communication channel 110, so that the pressing block 402 and the air pressure balance seat 300 do not apply acting force on the elastic sealing element 401. The elastic sealing member 401 is restored without being applied with force such that a gap is provided between the elastic sealing member 401 and the inner sidewall of the communication passage 110 to allow the communication passage 110 to communicate the inside and the outside of the refrigerating apparatus. The air outside the refrigerating device can flow into the inside of the refrigerating device through the gap in the communicating channel 110, so that the internal and external air pressures of the refrigerating device are balanced, and the acting force applied to the door body due to the air pressure difference is reduced, so that the door body can be smoothly opened.

In some alternative embodiments, elastomeric seal 401 includes a sealing rubber ring 4010, wherein sealing rubber ring 4010 is disposed around a circumferential sidewall of press block 402. The sealing rubber ring 4010 is bent, and the bent angle faces the air pressure balance seat 300. When the sealing assembly 400 moves towards the air pressure balance seat 300, the pressing block 402 drives the sealing rubber ring 4010 to abut against the air pressure balance seat 300, so that the sealing rubber ring 4010 extends along the axial direction of the communication channel 110.

With this optional embodiment, the sealing rubber ring 4010 is wound around the circumferential sidewall of the pressing block 402, and the sealing rubber ring 4010 is bent, and the bend angle faces the air pressure balance seat 300. Thus, when the seal assembly 400 moves toward the air pressure balance base 300, the seal ring 4010 abuts against the air pressure balance base 300. Under the continuous acting force of the pressing block 402, the angle of the bevel of the sealing rubber ring 4010 is gradually increased, so that the sealing rubber ring 4010 extends along the axial direction of the communication channel 110 to abut against the inner side wall of the communication channel 110, and the communication channel 110 is sealed.

As shown in fig. 2 to 4, alternatively, the air pressure equalizing seat 300 is configured with a communication hole 320 and an escape space 310 communicating with each other, the escape space 310 is opened toward the sealing assembly 400, and the escape space 310 is used to escape the sealing assembly 400. Along the axial direction of the communicating channel 110, one end of the sealing rubber ring 4010 is connected with the pressing block 402, and the other end of the sealing rubber ring 4010 can abut against the side wall at the opening of the avoiding space 310.

With this alternative embodiment, the seal assembly 400 is moved toward the air balance seat 300, and the air balance seat 300 is configured with an escape space 310, and the escape space 310 is used to escape the seal assembly 400. Optionally, the sealing assembly 400 may be connected to the air pressure balance base 300 through the escape space 310.

One end of the sealing rubber ring 4010 is connected with the pressing block 402, the other end of the sealing rubber ring 4010 can abut against the side wall of the opening of the avoiding space 310, and a bevel is formed between one end of the sealing rubber ring 4010 and the other end of the sealing rubber ring 4010. When the pressing block 402 moves the sealing rubber ring 4010 to the air pressure balance seat 300, the sealing rubber ring 4010 presses the side wall at the opening of the avoiding space 310, and the sealing rubber ring 4010 moves in the avoiding space 310 to compress the air in the avoiding space 310. The communication hole 320 communicates with the avoidance space 310 to allow the gas in the avoidance space 310 to flow to the outside to reduce the gas pressure in the avoidance space 310. When the pressing block 402 moves away from the air pressure balance base 300, the sealing rubber ring 4010 is conveniently separated from the air pressure balance base 300. Thus, the resistance of the sealing assembly 400 during movement can be reduced, and the reliability and stability of the balance air pressure of the door body of the refrigerating device can be improved.

In some alternative embodiments, the air pressure balance base 300 includes a base 301 and a slide 302. The slide way 302 is arranged at one side of the seat body 301, the slide way 302 extends along the rotation direction of the air pressure balancing seat 300, and the distance from the end of the slide way 302 to the wall surface of the seat body 301 is gradually reduced or gradually increased along the axial direction of the communicating channel 110. The sealing assembly 400 further comprises a connecting member 403, the connecting member 403 extends towards the air pressure balancing seat 300, the end of the connecting member 403 abuts against the end of the slide way 302, and the connecting member 403 can move relative to the end of the slide way 302. The air pressure balance base 300 rotates to drive the sealing assembly 400 to move away from the air pressure balance base 300 or move towards the air pressure balance base 300.

With this alternative embodiment, the slide way 302 extends along the rotation direction of the air pressure balance base 300, the connecting member 403 extends towards the air pressure balance base 300, and the end of the connecting member 403 abuts against the end of the slide way 302, so that the sealing assembly 400 is driven to move when the air pressure balance base 300 rotates. The connecting member 403 moves relative to the end of the slide 302, and the distance from the end of the slide 302 to the wall surface of the holder body 301 in the axial direction of the communicating passage 110 gradually decreases or gradually increases. When the slide way 302 rotates, the connecting member 403 is driven to gradually decrease or gradually increase in distance from the wall surface of the seat body 301. In this way, the distance between the sealing element 400 and the wall surface of the seat body 301 is gradually decreased or increased, so that the sealing element 400 moves away from the air pressure balance seat 300 or moves toward the air pressure balance seat 300 along the axial direction of the communication channel 110.

Optionally, the seat 301 is located in the communication channel 110.

In some alternative embodiments, the slide 302 is located on a side of the seat 301 facing away from the sealing assembly 400, when the handle assembly 200 is located at the first position, the distance from the end of the connecting member 403 to the wall surface of the seat 301 is a first distance, and when the handle assembly 200 is located at the second position, the distance from the end of the connecting member 403 to the wall surface of the seat 301 is a second distance, and the first distance is greater than the second distance.

That is, in the case that the distance between the end of the slide 302 and the wall surface of the seat 301 gradually decreases, the distance between the sealing assembly 400 and the air pressure balancing seat 300 gradually increases; in the case that the distance between the end of the slide way 302 and the wall surface of the seat body 301 gradually increases, the distance between the sealing assembly 400 and the air pressure balancing seat 300 gradually decreases.

When the handle assembly 200 is located at the first position, the sealing assembly 400 moves towards the air pressure balance base 300 to press the elastic sealing member 401 between the pressing block 402 and the air pressure balance base 300. When the handle assembly 200 is in the second position, the sealing assembly 400 moves away from the air pressure balancing seat 300, and the elastic sealing member 401 is reset, so that the communication passage 110 communicates the inside and the outside of the refrigeration device. The first distance in the first position is greater than the second distance in the second position, so that the third distance between the sealing assembly 400 and the air pressure balance seat 300 in the first position is less than the fourth distance between the sealing assembly 400 and the air pressure balance seat 300 in the second position.

Optionally, a sum of the first distance and the third distance is equal to a sum of the second distance and the fourth distance.

Optionally, the connecting member 403 is connected to the pressing block 402, and the connecting member 403 passes through the avoiding space 310 and abuts against the slide way 302.

The connecting piece 403 drives the pressing block 402 to move, so that the stress of the sealing rubber ring 4010 is more uniform, and the sealing effect of the sealing rubber ring 4010 on the communication channel 110 is improved.

In some alternative embodiments, the end of the connecting element 403 protrudes toward the slide way 302 to form a protrusion, the protrusion is engaged with the slide way 302, and the wall surface of the protrusion facing the seat 301 abuts against the wall surface of the slide way 302.

The handle assembly 200 includes a handle 201 and a fixing member 202, the handle 201 is sleeved on the rotation shaft 303, and the fixing member 202 passes through the handle 201 and is located in the fixing hole 330.

With this alternative embodiment, the rotating shaft 303 is provided with a fixing hole 330 along the radial direction of the rotating shaft 303, and the fixing member 202 is located in the fixing hole 330 through the handle 201. Therefore, the handle assembly 200 can be driven to move when rotating, and meanwhile, the handle assembly 200 and the air pressure balance seat 300 can be prevented from moving relatively, so that the door can work normally, and the stability and the reliability of the operation of the door are improved.

Alternatively, the fixing member 202 includes a bolt or a pin body, etc.

As shown in fig. 3, in some alternative embodiments, the door body for the refrigeration device further includes an elastic assembly 500, the elastic assembly 500 is supported between the air pressure balancing seat 300 and the sealing assembly 400, and the elastic assembly 500 is used for providing a force to the sealing assembly 400 away from the air pressure balancing seat 300.

With this alternative embodiment, the elastic member 500 is supported between the air pressure balance seat 300 and the sealing member 400, and when the handle assembly 200 is rotated to the second position, the elastic member 500 provides a force to the sealing member 400 away from the air pressure balance seat 300, so that the sealing member 400 can be reset to enable the communication passage 110 to communicate the inside and the outside of the refrigeration apparatus. When the handle assembly 200 is rotated to the first position, the air pressure balance base 300 overcomes the force of the elastic assembly 500, so that the sealing assembly 400 seals the communication channel 110.

For example, the slide way 302 is located on a side of the seat body 301 facing away from the sealing assembly 400, the connecting member 403 extends toward the air pressure balancing seat 300, and a distal end of the connecting member 403 abuts against an end of the slide way 302. When the handle assembly 200 is rotated from the first position to the second position, the distance from the end of the slide 302 to the wall of the seat 301 gradually decreases. The resilient assembly 500 is supported between the air balance seat 300 and the seal assembly 400, and the resilient assembly 500 provides a force to the seal assembly 400 away from the air balance seat 300, i.e., provides a force to the connector 403 adjacent to the slide 302. So that the connecting piece 403 is always abutted to the slideway 302, the sealing assembly 400 is reset, and the communicating channel 110 is communicated with the inside and the outside of the refrigerating device, thereby improving the reliability and the stability of the door body.
