Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a door body for a refrigerator and a refrigerator. Background Art

[0002] At present, when a freezer is in use, the temperature inside the freezer decreases due to the refrigeration effect inside the freezer, which reduces the air pressure inside the freezer, causing the air pressure inside the freezer to be lower than the air pressure outside the freezer, resulting in negative pressure, making it difficult to open the freezer door. The formation process of the negative pressure phenomenon is roughly as follows: after the door is opened, gas exchange occurs between the inside and outside of the freezer compartment, and hot air from the outside enters the freezer compartment; after the door is closed, the temperature of the hot air in the compartment gradually decreases under the effect of refrigeration, and the pressure in the compartment decreases, resulting in a pressure difference between the inside and outside of the freezer. This causes the user to need a lot of force to open the door.

[0003] The related technology discloses a door body with an air pressure balancing function, including an insulation door and a handle, the insulation door including an outer shell and a door lining, an insulation layer is arranged between the outer shell and the door lining, a ventilation pipe is also arranged in the insulation door, a first through hole is opened on the side wall of the outer shell, a second through hole is opened on the door lining, the ventilation pipe is connected between the first through hole and the second through hole, and a valve for opening and closing the first through hole is arranged on the handle.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The valve in the related art is a sealing ball. As the door is opened and closed, the sealing ball is easy to roll, and the relative position of the sealing ball and the first through hole may shift, so that the sealing ball cannot completely close the first through hole, causing cold leakage. Moreover, as the door is opened and closed, the structural strength of the connection between the sealing ball and the handle decreases, and the sealing ball is easy to fall off from the handle, thereby failing to close the first through hole.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0044] Combination Figure 1-7 As shown, an embodiment of the present disclosure provides a door body 10 for a refrigerator, and the refrigerator includes a box body, and the door body 10 is arranged in the box body and defines a refrigeration space together with the box body. The door body 10 includes a vent 20 and a damper 30. The vent 20 is configured to connect the refrigeration space and the external environment. The vent 20 includes a first end 21 and a second end 22, the first end 21 is connected to the external environment, and the second end 22 is connected to the refrigeration space. The damper 30 is arranged at the first end 21, and when subjected to an external force, the damper 30 can be rotated to expose the first end 21, so that the inside of the vent 20 is connected to the external environment; after the external force is eliminated, the damper 30 can be rotated to a position covering the first end 21, so that the inside of the vent 20 is separated from the external environment.

[0045] The door body 10 for a refrigerator provided by the embodiment of the present disclosure is adopted, and a vent pipe 20 is arranged on the door body 10. The first end 21 of the vent pipe 20 is connected to the external environment, and the second end 22 is connected to the refrigeration space. A damper 30 is arranged at the first end 21. When the damper 30 is opened, the refrigeration space and the external environment are connected through the vent pipe 20, the refrigerator is depressurized, and the pressure difference inside and outside the refrigerator is balanced, so that the user can open the door more labor-saving; when the damper 30 is closed, the refrigeration space and the external environment are separated by the damper 30, and gas exchange cannot be carried out through the vent pipe 20. The refrigeration space is in a closed state, which can prevent cold leakage and save energy. Moreover, compared with the related art, the damper 30 in the embodiment of the present disclosure has a simple structure, does not roll, and has better structural stability.

[0046] Optionally, the damper 30 includes a tube body 31 and a cover body 32. The tube body 31 is disposed at the first end 21, and the tube body 31 is provided with a cavity 311 extending along its length direction. The cavity 311 is communicated with the first end 21. The cover body 32 is rotatably connected to the tube body 31, and when subjected to an external force, the cover body 32 can rotate relative to the tube body 31 to expose the outlet of the cavity 311; after the external force is eliminated, the cover body 32 can rotate relative to the tube body 31 to cover the outlet of the cavity 311.

[0047] In this way, the cover 32 and the tube body 31 are rotatably connected, and the opening and closing of the damper 30 is controlled by the change of the relative position of the cover 32 and the tube body 31, so as to realize the connection and separation between the inside and outside environment of the vent pipe 20. When the cover 32 is subjected to external force, the cover 32 can rotate relative to the tube body 31 to expose the outlet of the cavity 311. At this time, the first end 21 of the vent pipe 20 is unobstructed, and the air of the external environment can enter the refrigeration space from the vent pipe 20 under the action of the pressure difference, balancing the air pressure inside and outside the refrigerator, making the user's door opening process more labor-saving. After the external force is eliminated, the cover 32 can rotate relative to the tube body 31 to cover the outlet of the cavity 311. At this time, the inside and outside environment of the vent pipe 20 are separated, and the refrigeration space is in a closed state, which can prevent the leakage of cold and save energy.

[0048] Optionally, combined Figure 3 As shown, the door body 10 further includes a handle 40, which is disposed outside the damper 30 and includes a body 41 and a pressing structure 42. The pressing structure 42 can move toward the damper 30 relative to the body 41 to apply a force to the cover 32, thereby opening the damper 30.

[0049] In this way, by applying a force to the cover body 32 through the pressing structure 42, the cover body 32 is rotated relative to the tube body 31 to expose the outlet of the cavity 311, thereby realizing the opening of the damper 30. At this time, the inside of the ventilation pipe 20 and the external environment are connected, the pressure of the refrigerator is released, and the pressure inside and outside the refrigerator tends to be balanced, making the process of opening the door more labor-saving for the user.

[0050] Optionally, combined Figure 2 and Figure 3 As shown, the handle 40 further includes an elastic member 43 , which is disposed between the pressing structure 42 and the body 41 , and is connected to the pressing structure 42 and the body 41 , respectively.

[0051] When the user applies force to the pressing structure 42, the elastic member 43 is compressed by the force, stores elastic potential energy, and drives the pressing structure 42 to move relative to the body 41 toward the damper 30; when the external force disappears, the elastic member 43 releases the elastic potential energy, thereby driving the pressing structure 42 to move relative to the body 41 away from the damper 30, thereby changing the position of the pressing structure 42 relative to the body 41 to open or close the damper 30. Moreover, the structure is simple, the operation is easy, and the cost is saved.

[0052] Optionally, the elastic member 43 is a spring or a spring sheet.

[0053] Optionally, combined Figure 4 and Figure 5 As shown, the pressing structure 42 includes an abutting portion 421, which abuts against the cover 32. When the pressing structure 42 moves toward the damper 30 relative to the body 41, a force is applied to the cover 32, so that the cover 32 rotates relative to the tube body 31 to expose the outlet of the cavity 311.

[0054] In this way, through the abutment cooperation between the abutment portion 421 and the cover body 32, when the pressing structure 42 moves toward the damper 30 relative to the main body 41, the abutment portion 421 applies a force to the cover body 32, so that the cover body 32 rotates relative to the tube body 31 to expose the outlet of the cavity 311. At this time, the interior of the ventilation pipe 20 is connected to the external environment, and the air of the external environment can enter the refrigeration space from the ventilation pipe 20 under the action of the pressure difference, thereby balancing the air pressure inside and outside the refrigerator, making the user's door opening process more labor-saving.

[0055] For example, the cover body 32 and the tube body 31 are rotatably connected via a rotating shaft, and the rotating shaft includes a fixed member 315 and a rotating member 322. The fixed member 315 is provided on the tube body 31, and the rotating member 322 is provided on the cover body 32. It can be understood that if the rotating shaft is located in the upper area of ​​the outlet of the cavity 311, then the position on the cover body 32 that abuts against the abutting portion 421 must be located above the rotating member 322, so that the rotation of the cover body 32 can be achieved.

[0056] Optionally, combined Figure 6 As shown, the tube body 31 includes a baffle 316 , and the fixing member 315 is disposed on the baffle 316 .

[0057] In this way, the baffle 316 can prevent the cold air in the refrigeration space from overflowing from the connection between the fixed part 315 and the rotating part 322 to the external environment, thereby preventing the refrigerator from leaking cold air and saving energy.

[0058] Optionally, combined Figures 2 to 6As shown, the tube body 31 includes a first tube body 312, a second tube body 313 and a limiting structure 314. The first tube body 312 is inserted into the first end 21, and the second tube body 313 is connected to the first tube body 312 and extends out of the first end 21. The cover body 32 is disposed on the second tube body 313. The limiting structure 314 is disposed between the first tube body 312 and the second tube body 313. One side of the limiting structure 314 abuts against the body 41, and the other side abuts against the pipe opening of the first end 21.

[0059] The first tube body 312 is inserted into the first end 21, the second tube body 313 is connected to the first tube body 312 and extends out of the first end 21, and the cover body 32 is arranged on the second tube body 313. In this way, from the outside to the inside of the refrigerator, the pressing structure 42, the cover body 32, the second tube body 313, and the ventilation pipe 20 are arranged in sequence. By controlling the position of the cover body 32 relative to the second tube body 313, the connection or separation of the internal and external environments of the ventilation pipe 20 is controlled, thereby realizing the pressure relief or sealing of the refrigerator to meet various needs.

[0060] The limiting structure 314 is arranged between the first tube body 312 and the second tube body 313. One side of the limiting structure 314 abuts against the main body 41, and the other side abuts against the pipe mouth of the first end 21. In this way, not only can the installation position of the first tube body 312 and the second tube body 313 be preliminarily located, but also the first tube body 312 and the second tube body 313 can be limited from moving outward or inward during subsequent use.

[0061] Optionally, combined Figure 4 and Figure 5 As shown, the limiting structure 314 is annular and sleeved on the outer peripheral side of the tube body 31 .

[0062] It can be understood that the ring includes two concentric circles, the outer circumference of the small circle overlaps with the outer circumference of the tube body 31, and the radius of the large circle is larger than the diameter of the first end 21 of the ventilation tube 20 to achieve a limiting effect.

[0063] Optionally, combined Figure 5 As shown, a spiral structure 3121 is provided on the outer circumference of the first tube body 312 .

[0064] In this way, the spiral structure 3121 is provided on the outer peripheral side of the first tube body 312 , which can facilitate the first tube body 312 to be rotated and inserted into the first end 21 of the ventilation pipe 20 to complete the connection with the first end 21 .

[0065] Optionally, combined Figure 6 and Figure 7 As shown, the second tube body 313 is engaged with the main body 41 .

[0066] In this way, the handle 40 and the damper 30 are connected together through the clamping connection between the second tube 313 and the body 41 .

[0067] Optionally, combined Figure 6 and Figure 7 As shown, a mounting hole 411 having a thickness of the main body 41 is provided on a surface facing the second tube 313 , and the second tube 313 cooperates with the pressing structure 42 after passing through the mounting hole 411 .

[0068] Optionally, the second tube body 313 includes a buckle 3131 , and the main body 41 is correspondingly provided with a buckle slot 412 , and the buckle 3131 is connected to the buckle slot 412 , so that the main body 41 is connected to the second tube body 313 .

[0069] In this way, the second tube body 313 is clamped with the main body 41, the first tube body 312 is plugged with the first end 21 of the ventilation pipe 20, the limiting structure 314 abuts between the main body 41 and the first end 21, the position of the tube body 31 in the inner and outer directions of the door body 10 is fixed, and the fixing method is simple and easy to assemble.

[0070] Optionally, combined Figure 2 and Figure 5 As shown, the cover body 32 is provided with a groove 321, and the damper 30 further includes a counterweight 33, which is arranged in the groove 321. The counterweight 33 is configured to rotate the cover body 32 under its own gravity to cover the outlet of the cavity 311, thereby closing the cavity 311.

[0071] In this way, when there is no external force, the gravity of the counterweight block 33 itself can make the cover body 32 fit relatively tightly on the tube body 31 to cover the outlet of the cavity 311, thereby isolating the air flow between the inside of the ventilation pipe 20 and the external environment, and ensuring the sealing of the refrigeration space.

[0072] Optionally, combined Figure 2 and Figure 3 As shown, the door body 10 further includes a door shell 50, a door lining 60 and a decoration box 70. The door lining 60 is arranged inside the door shell 50, and a heat preservation layer is arranged between the door lining 60 and the door shell 50. The ventilation pipe 20 is arranged inside the heat preservation layer. The decoration box 70 is connected to the second end 22, and the decoration box 70 is provided with a ventilation hole 71, and the ventilation hole 71 is located inside the door lining 60.

[0073] That is, the door body 10 of the embodiment of the present disclosure is a door body 10 with an air pressure balance function. A vent pipe 20 connecting the inside and outside of the refrigerator box is provided in the insulation layer of the door body 10. The outer pipe opening (first end 21) of the vent pipe 20 is connected to the tube body 31 of the damper 30. The tube body 31 is provided with a cavity 311, and the cavity 311 is opened or closed by the cover body 32. In actual use, when the door body 10 is closed, a negative pressure will be formed inside the refrigerator box due to the low temperature. When the user needs to open the door body 10, it is only necessary to drive the cover body 32 to open the cavity 311, and the vent pipe 20 is connected with the external environment. Under the action of the external atmospheric pressure, the external air enters the vent pipe 20 and enters the refrigeration space through the vent hole 71 on the decorative box 70 to achieve air pressure balance, thereby achieving air pressure balance inside and outside the box.

[0074] By arranging the vent 20 in the insulation layer, arranging the damper 30 between the vent 20 and the external environment, and arranging a pressing structure 42 for opening and closing the damper 30 on the handle 40, when the user opens the door, the damper 30 is driven to open by the pressing structure 42, so that the vent 20 is connected to the external environment. In this way, under the action of the external atmospheric pressure, the external air enters the refrigeration space through the vent 20 to balance the pressure inside the refrigerator, and the door opening operation is performed after the requirement of the internal and external air pressure balance is achieved, which saves effort to open the door and improves the user experience.

[0075] Optionally, the door body 10 further includes a gas processing structure, which is disposed in the decoration box 70 and is used to process the gas entering the decoration box 70 from the ventilation pipe 20. The gas processing structure includes at least one of a molecular sieve and a sterilization block.

[0076] In this way, the air entering the ventilation pipe 20 from the external environment is sterilized and / or dehydrated by the gas processing structure placed in the decorative box 70, and the treated air is allowed to enter the refrigeration space, reducing the impact on the internal environment of the box.

[0077] The embodiment of the present disclosure provides a refrigerator, comprising a cabinet and a door 10. The door 10 is openably disposed on the cabinet, and defines a refrigeration space together with the cabinet.

[0078] The freezer can be a vertical freezer or a horizontal freezer.

[0079] Optionally, there are two pressing structures 42 , which are arranged opposite to each other in the up-down direction or in the left-right direction. There are also two vent pipes 20 and two dampers 30 , and each vent pipe 20 corresponds to one damper 30 and one pressing structure 42 .

[0080] It can be understood that when the refrigerator is a vertical refrigerator, the pressing structure 42 is relatively arranged along the up-down direction of the body 41; when the refrigerator is a horizontal refrigerator, the pressing structure 42 is relatively arranged along the left-right direction of the body 41.

[0081] In this way, by increasing the number of ventilation pipes 20, the air pressure balance time inside and outside the refrigerator can be further accelerated, the door opening waiting time can be shortened, and the user experience can be improved.

[0082] In addition, in order to further speed up the pressure relief speed, the diameter of the ventilation pipe 20 can also be thickened to increase the air intake volume to further shorten the door opening waiting time.
