Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] A freezer is a common refrigeration equipment. A freezer generally includes a cabinet body with a storage room, a cabinet door for opening or closing the storage room, and a refrigeration system for providing cold air to the storage room. When the freezer is refrigerated, that is, when the refrigeration system is running, the air temperature in the storage room decreases and the volume shrinks. Since the storage room is a closed space, negative pressure is formed in the storage room, making it difficult to open the cabinet door. A ventilation device is generally provided in the door body, which can balance the air pressure in the storage room and the external space, relieve the negative pressure in the storage room, and facilitate users to open the cabinet door at any time.

[0003] In the related art, the cabinet door usually includes a door liner, a door shell and an insulation layer that are arranged relatively and connected, and a storage space is enclosed between the door liner and the door shell. The door liner is provided with a first air vent. The door shell is provided with a second air vent. The insulation layer is filled in the storage space. The ventilation device is located in the storage space and is wrapped by the insulation layer. The ventilation device generally includes a mounting seat, an air vent and a ventilation valve. The mounting seat is fixed to the door liner by tape. The mounting seat is provided with an air vent, one end of the air vent is connected to the first air vent, the other end of the air vent is connected to the first end of the air vent, and the second end of the air vent is connected to the second air vent. The air valve is arranged on the air vent to control the on and off of the air in the air vent. When the air valve is in an open state, the air in the external space enters the air vent through the second air vent, and enters the storage room through the air vent and the first air vent to relieve the negative pressure in the storage room.

[0004] However, in the refrigerator in the related art, when the insulation layer is made by foaming the insulation material, the insulation material is easy to leak from between the mounting base and the door liner. Utility Model Content

[0005] The disclosed embodiment provides a refrigerator, which can solve the technical problem in the related art that when the insulation layer is made by foaming the insulation material, the insulation material is easily leaked from between the mounting seat and the door liner.

[0011] The mounting seat is provided with a ventilation channel, wherein the ventilation channel forms a first opening on the mounting seat, and the first opening is communicated with the second end of the ventilation tube; the ventilation channel forms a second opening at the bottom end of the mounting seat, and the second opening is opposite to the first ventilation hole; a second connecting protrusion is provided on the circumferential side of the bottom end of the mounting seat, and the second connecting protrusion is butted against the first connecting protrusion;

[0012] A sealing ring, wherein a connecting recessed portion is arranged on the inner side of the sealing ring, and the connecting recessed portion is sleeved on the first connecting protruding portion and the second connecting protruding portion.

[0013] In the refrigerator of the disclosed embodiment, the sealing ring can be sleeved on the first connecting protrusion and the second connecting protrusion via the connecting recess. The sealing ring seals the first connecting protrusion and the second connecting protrusion and can block the foamed heat-insulating material to prevent the heat-insulating material from leaking from between the mounting seat and the door liner as much as possible.

[0020] In some embodiments of the present disclosure, a first avoidance recess is provided on a side of the second sealing portion facing away from the door liner, and the first avoidance recess abuts against a partial surface of the mounting seat.

[0021] Such an arrangement can make the second sealing portion tightly abut against a part of the surface of the mounting seat, thereby improving the sealing performance of the connection between the mounting seat and the door liner and preventing interference between the mounting seat and the sealing ring as much as possible.

[0023] With such arrangement, during the installation of the second seal, the fourth sub-connection recess of the fourth seal can be firstly sleeved on the first connection part and the fifth connection part, and the sixth sub-connection recess of the sixth seal can be sleeved on the third connection part and the seventh connection part. Then the fourth seal and the sixth seal are pushed so that the fifth sub-connection recess of the fifth seal is sleeved on the fourth connection part and the eighth connection part. The first connection part and the fifth connection part can guide the fourth seal through the fourth sub-connection recess, and the third connection part and the seventh connection part can guide the sixth seal through the sixth sub-connection recess, so that the fifth sub-connection recess of the fifth connection part can be accurately sleeved on the fourth connection part and the eighth connection part, thereby preventing the second seal from being deflected as much as possible, and improving the position accuracy and convenience when installing the second seal.

[0024] In some embodiments of the present disclosure, a second avoidance recess is provided on a side of the fifth sealing portion facing away from the door liner, and the second avoidance recess abuts against a partial surface of the mounting seat.

[0025] Such an arrangement can make the fifth sealing portion tightly abut against a part of the surface of the mounting seat, thereby improving the sealing performance of the connection between the mounting seat and the door liner and preventing interference between the mounting seat and the sealing ring as much as possible.

[0026] In some embodiments of the present disclosure, at two opposite ends of the first seal and the second seal, one is provided with an inserting recess, and the other is provided with an inserting protrusion, and the inserting protrusion is inserted into the inserting recess.

[0027] With such arrangement, the first seal and the second seal can be connected by means of the plug-in recess and the plug-in protrusion, which can improve the connection strength between the first seal and the second seal, thereby preventing the first seal and the second seal from separating as much as possible and improving the structural reliability of the sealing ring.

[0081] In order to make the purpose, implementation mode and advantages of the present disclosure clearer, the exemplary implementation mode of the present disclosure will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present disclosure. Obviously, the described exemplary embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments.

[0082] It should be noted that the brief description of terms in the present disclosure is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of the present disclosure.

[0087] The refrigerator in the related art has a technical problem that when the insulation layer is made by foaming the insulation material, the insulation material is easy to leak from the mounting seat and the door liner. The inventor has found that the reason is that the mounting seat is fixed to the door liner by tape, resulting in poor sealing between the mounting seat and the door liner. When the insulation layer is made by foaming the insulation material, the insulation material is easy to leak from the mounting seat and the door liner.

[0088] In view of this, an embodiment of the present disclosure provides a refrigerator, wherein a mounting portion is provided on a side of a door liner facing a door shell, a first air vent is provided on the mounting portion, and a first connecting protrusion is provided on a circumferential side of the mounting seat. The air vent in the mounting seat forms a second opening opposite to the first air vent at the bottom end of the mounting seat, and a second connecting protrusion is provided on the circumferential side of the bottom end of the mounting seat, the second connecting protrusion being opposite to the first connecting protrusion. A sealing ring is provided, and the sealing ring is configured as a sealing sleeve provided on the first connecting protrusion and the second connecting protrusion that are connected to each other, so that the first connecting protrusion and the second connecting protrusion are sealed and connected, thereby improving the sealing between the mounting portion and the mounting seat, thereby improving the sealing between the door liner and the mounting seat, and further preventing the thermal insulation material from leaking from between the door liner and the mounting seat as much as possible.

[0089] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0090] refer to Figure 1 and Figure 2 , the refrigerator of the embodiment of the present disclosure may include a cabinet body 100 and a door body 200. The cabinet body 100 may be configured with a storage chamber 110. The storage chamber 110 may be used to store items such as food. The door body 200 may be rotatably connected to the cabinet body 100 for opening or closing the storage chamber 110. Exemplarily, the door body 200 may be rotatably connected to the cabinet body 100 via a hinge assembly 300. In some possible implementations of the embodiment of the present disclosure, a storage basket may also be provided in the storage chamber 110, and the user may place items in the storage basket. By providing the storage basket, the space utilization rate of the storage chamber 110 may be improved.

[0091] Exemplarily, the cabinet 100 may include a cabinet housing 130, a cabinet liner 120, and a first insulation layer (not shown in the drawings). The cabinet housing 130 may be configured with a storage chamber with an open top. The cabinet housing 130 may form the appearance of a refrigerator. The cabinet liner 120 may be located in the storage chamber, and the cabinet liner 120 may be configured with a storage chamber 110 with an open top. The storage chamber 110 is used to place items such as food. The first insulation layer may be filled between the cabinet liner 120 and the cabinet housing 130 to insulate the storage chamber 110, reduce the heat exchange between the storage chamber 110 and the outside of the refrigerator, and thus reduce the energy consumption of the refrigerator. Exemplarily, in some possible implementations of the present disclosure, the insulation material may be foamed and filled between the cabinet housing 130 and the cabinet liner 120 to form a first insulation layer.

[0092] The cabinet 100 may further include a cabinet frame 140. The cabinet frame 140 may be located between the cabinet liner 120 and the cabinet housing 130, and connect the top edge of the cabinet housing 130 and the top edge of the cabinet liner 120. The cabinet frame 140 may connect the cabinet housing 130 and the cabinet liner 120 to form a complete cabinet 100, and may improve the appearance of the refrigerator. In addition, when the insulation layer is made by a foaming process, the cabinet frame 140 may form a closed space in the accommodation chamber between the cabinet liner 120 and the cabinet housing 130, so that the insulation material is blocked after foaming, thereby preventing the insulation layer from leaking as much as possible.

[0093] Exemplarily, the door body 200 may include a door liner 210, a door shell 220, and a second insulation layer (not shown in the drawings). The door liner 210 may face the storage chamber 110 when the door body 200 is closed. The door shell 220 is arranged opposite to the door liner 210 to form the appearance of the refrigerator. The second insulation layer may be filled between the door liner 210 and the door shell 220 to insulate the storage chamber 110 when the door body 200 is closed, reduce the heat exchange between the storage chamber 110 and the outside of the refrigerator, and thus reduce the energy consumption of the refrigerator. Exemplarily, in some possible implementations of the present disclosure, the second insulation layer may be formed by foaming the insulation material and filling it between the cabinet shell 130 and the cabinet liner 120.

[0094] The refrigerator of the disclosed embodiment may further include a refrigeration system (not shown in the drawings), which is used to provide cold for the storage chamber 110. Exemplarily, the refrigeration system may include a compressor, a condenser, a capillary tube, and an evaporator connected in a loop. When the refrigeration system is running, the compressor compresses the refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor, and transports the refrigerant vapor to the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate a high-temperature and low-pressure refrigerant liquid, which is transported to the capillary tube. After the capillary tube depressurizes the refrigerant liquid, the high-pressure and low-temperature refrigerant liquid is converted into a low-pressure and low-temperature refrigerant liquid, which is transported to the evaporator. After the evaporator receives the low-pressure and low-temperature refrigerant liquid, it boils it under isobaric conditions, absorbs heat and vaporizes it to form refrigerant vapor to reduce the temperature in the storage chamber 110.

[0095] The refrigerator of the disclosed embodiment may further include a ventilation device 400, which can balance the air pressure between the storage chamber 110 and the outside of the refrigerator, relieve the negative pressure state in the storage chamber 110, and facilitate the user to open the cabinet door at any time.

[0096] For example, reference Figure 3 , Figure 4 and Figure 5 , the door liner 210 may be provided with a first air vent 211. The door shell 220 may be provided with a second air vent 221. The ventilation device 400 may be located between the door liner 210 and the door shell 220, and may be wrapped by a second heat-insulating layer to achieve a ventilation function without affecting the appearance and heat-insulating performance of the refrigerator. The ventilation device 400 may be connected to the first air vent 211 and the second air vent 221. The air outside the refrigerator may enter the ventilation device 400 through the second air vent 221, and then enter the storage chamber 110 from the ventilation device 400 and the first air vent 211, so that the air pressure inside the storage chamber 110 is balanced with the air pressure outside the refrigerator, thereby relieving the negative pressure state inside the storage chamber 110 and facilitating the user to open the cabinet door at any time.

[0097] Continue to refer Figure 6 and Figure 7The ventilation device 400 may include a ventilation tube 410 and a mounting seat 420, and the first end of the ventilation tube 410 may be communicated with the first ventilation hole 211. The mounting seat 420 may be provided with a ventilation channel S, and the ventilation channel S forms a first opening H1 on the mounting seat 420, and the first opening H1 may be communicated with the second end of the ventilation tube 410. The ventilation channel S may form a second opening H2 at the bottom end of the mounting seat 420, and the second opening H2 may be communicated with the first ventilation hole 211. The air outside the refrigerator may enter the ventilation tube 410 through the first ventilation hole 211, then enter the ventilation channel S of the mounting seat 420 through the first opening H1, and then enter the storage chamber 110 through the second opening H2 and the second ventilation hole 221.

[0098] Exemplarily, the air vent 410 may include a detachably connected first pipe segment 411 and a second pipe segment (not shown in the drawings). The first end of the first pipe segment 411 may be communicated with the first air hole 211, the second end of the first pipe segment 411 may be communicated with the first end of the first pipe segment 411, and the second end of the first pipe segment 411 may be communicated with the first opening H1 of the air passage S. Since the air vent 410 includes a detachably connected first pipe segment 411 and a second pipe segment, when the first pipe segment 411 or the second pipe segment is worn or damaged, it can be removed and replaced without replacing the entire air vent 410, thereby reducing the maintenance cost and time of the air vent 410. In addition, the length and configuration of the first pipe segment 411 and the second pipe segment may be adjusted according to specific needs to adapt to different models of refrigerators.
