Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an improvement on the structure of a refrigerator. Background Art

[0002] As a common household appliance, refrigerators are also one of the most power-consuming appliances. There are many factors that affect the energy consumption of refrigerators, among which the sealing of the door seal is an important factor. In order to reduce the cold leakage of refrigerators, improve the refrigeration effect, and reduce electricity consumption, improving the sealing performance of the door seal is the most direct way.

[0003] However, the door seals of existing refrigerators are mostly provided with a circle of sealing strips between the door body and the cabinet body. Sometimes, gaps are formed due to the bending of the door body decorative strips and uneven foaming, which will cause cold leakage.

[0004] In order to further enhance the sealing, some refrigerators are arranged with two layers of sealing strip structures, which are set on different steps. The double-layer sealing effect is achieved by the cooperation of the inner and outer layers of sealing strips. There is a gap between the existing double-layer sealing strips when they are closed. The gap between the two layers of sealing strips can easily cause cold and hot air to converge and remain, resulting in local gap condensation, affecting the user experience.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

[0043] In some embodiments of the present application, a refrigerator is provided.

[0044] The refrigerator comprises a cabinet body 100. The cabinet body 100 defines an outer shape of the refrigerator. An accommodating space is defined in the cabinet body 100. One end of the cabinet body 100 is open to form an open end of the cabinet body.

[0045] In some embodiments, the refrigerator may be a horizontal refrigerator, the cabinet opening end of which is formed at the top of the cabinet 100 , and the user takes out and puts items that need to be stored at low temperatures from the cabinet opening end at the top.

[0046] The inner liner 200 is arranged in the accommodating space of the cabinet 100, and a storage space 210 is defined inside the inner liner 200;

[0047] An insulated storage space 210 is defined inside the inner liner 200 as a storage compartment for storing items that need to be kept at low temperatures. The inner liner 200 is open toward the opening end of the cabinet 100 to form an opening end of the inner liner 200. In order to achieve good heat transfer and thermal conductivity, the inner liner 200 is generally made of metal.

[0048] An open portion is formed at the top circumference of the cabinet 100 and the top circumference of the inner container 200 .

[0049] The cabinet opening 300 is connected to the cabinet body 100 and the top of the inner container 200 to seal the open portion formed between the cabinet body 100 and the top of the inner container 200 .

[0050] In some embodiments, an annular clamping flange 350 is formed on the outer side of the cabinet opening 300 , and an annular insertion slot 360 is formed on the inner side of the cabinet opening 300 , and the notch of the insertion slot 360 is arranged downward.

[0051] During assembly, the cabinet opening 300 is buckled at the open part, and its outer side is clamped on the outer surface around the cabinet body 100 through the clamping flange 350, and its interior is plugged and matched with the inner liner 200 through the insertion groove 360 ​​to realize the connection between the cabinet opening 300 and the inner liner 200 and the cabinet body 100.

[0052] To achieve cooling of the storage space 210, in some embodiments, an evaporator tube is wound around the inner wall of the inner tank 200 and connected to the compressor via a refrigerant pipeline to transfer cold energy to the inner tank 200 and the internal storage space 210 through the evaporator tube.

[0053] The cabinet door 400 is connected to the cabinet body 100 and is used to open and close the storage space 210 .

[0054] In some embodiments, the cabinet door 400 is arranged above the cabinet body 100 , and one side of the cabinet door 400 is rotatably connected to the cabinet body 100 via a hinge, so as to open or close the storage space 210 by rotating relative to the cabinet body 100 .

[0055] In some embodiments, the cabinet door 400 includes a door front shell 420, which is used to form the front surface of the cabinet door 400;

[0056] The door liner 410 is arranged in parallel with the door front shell 420 , and when the door body is closed, it is at least partially inserted into the storage space 210 to cooperate with the cabinet opening 300 to close the cabinet body 100 .

[0057] The door end stop 430 is connected between the door front shell 420 and the door liner 200, and is surrounded by the door front shell 420 and the door liner 410 to form a foaming cavity, in which the foaming cavity is filled with foaming material to achieve heat preservation and insulation of food in the storage space 210 when the cabinet door 400 is closed.

[0058] The sealing component 500 is arranged on the door liner 410 and / or the cabinet opening 300 . A plurality of sealing components 500 are provided. The plurality of sealing components 500 are arranged in sequence from the outside to the inside along the cabinet body 100 .

[0059] The storage space 210 disposed in the inner container 200 of the cabinet 100 is located at the innermost part, and the direction from the outside to the inside of the cabinet 100 refers to the direction from the direction away from the storage space 210 to the direction close to the storage space 210 .

[0060] In some embodiments, the sealing component 500 is an EPDM sealing strip, a silicone rubber sealing strip, a chloroprene rubber sealing strip, a nitrile rubber sealing strip or a polyurethane rubber sealing strip.

[0061] The sealing components 500 are arranged in plurality along the cabinet body 100 from the outside to the inside, so as to realize multi-layer sealing inside and outside the refrigerator cabinet body 100. The plurality of sealing components 500 are used to form multi-level partitions between the inner and outer spaces of the cabinet body 100, so as to ensure the reliability and stability of the sealing and ensure the sealing effect.

[0062] In some embodiments, a plurality of sealing components 500 are arranged on the cabinet opening 300 and arranged in sequence from the outside to the inside along the cabinet body 100. When the cabinet door 400 is closed, the plurality of sealing components 500 are compressed and connected to achieve sealing.

[0063] In some embodiments, multiple sealing components 500 are arranged on the door liner 410 and arranged in sequence from the outside to the inside along the cabinet body 100. When the cabinet door 400 is closed, the cabinet door 400 and the cabinet opening 300 cooperate with each other to compress the multiple sealing components 500 to achieve sealing.

[0064] In some embodiments, some of the multiple sealing components 500 are arranged on the cabinet opening 300, and some of the sealing components 500 are arranged on the door liner 410. Multiple sealing components 500 are alternately arranged on the cabinet opening 300 and the door liner 410 along the cabinet body 100 from the outside to the inside.

[0065] When the cabinet door 400 is closed, both the sealing component 500 on the door liner 410 and the sealing component 500 on the cabinet opening 300 can be compressed by the squeezing force of the cabinet door 400 and the cabinet opening 300 to seal the cabinet opening 300 and the cabinet door 400 .

[0066] The sealing component 500 is arranged partially on the cabinet opening 300 and partially on the door liner 410. This can prevent the problem of sealing failure caused by installing the sealing component 500 on one of the components. Because the sealing component 500 is assembled on the door liner 410 or the cabinet opening 300, if the door liner 410 or the cabinet opening 300 is deformed due to assembly deviation or processing deviation, the position of the sealing component 500 will be changed, and complete sealing cannot be performed, which affects the sealing performance of the sealing component 500.

[0067] A plurality of sealing components 500 are provided and installed on two different components, so that when the sealing component 500 above one of the components fails due to processing deviation or deformation, the sealing component 500 on the other component can still ensure its sealing effect.

[0068] When the cabinet door 400 is closed, the plurality of sealing components 500 are deformed and connected to each other by the extrusion of the cabinet door 400 and the cabinet opening 300 to seal the cabinet opening 300 and the door liner 410 .

[0069] When multiple sealing components 500 are arranged on the door liner 410 and / or the cabinet opening 300, when the cabinet door 400 is closed, the door liner 410 and the cabinet opening 300 on the cabinet door 400 cooperate with each other. At this time, the sealing components 500 located between the door liner 410 and the cabinet opening 300 will be compressed, and the squeezed multiple sealing components 500 will be deformed, and the multiple sealing components 500 will be fitted and connected together.

[0070] During the setting, the spacing between the multiple sealing components 500 can be reasonably set to ensure that they can fit and connect with each other after being pressed.

[0071] In the arrangement of the existing multi-layer sealing strips of the refrigerator, there is a gap between adjacent sealing strips. When the cabinet door 400 is closed, there is also a gap between adjacent sealing strips. In this way, when the refrigerator is running for cooling, the cold air flowing out from the storage space 210 of the refrigerator may pass through the inner sealing strip and be deposited on the cabinet opening 300 at the gap position between the inner sealing strip and the outer sealing strip. At the same time, external airflow may also enter this gap from the outer sealing strip.

[0072] At this time, the internal cold air flow and the external hot air may meet and remain in the gap between the two layers of sealing strips. The meeting of cold and hot air flow will produce condensation in this gap, affecting the user experience.

[0073] In order to avoid the above-mentioned problem, when the cabinet door 400 is closed, the plurality of sealing components 500 are squeezed and connected to each other to form a large sealing area.

[0074] Adjacent sealing components 500 are closely connected, that is, there is no gap between any adjacent sealing components 500 after being closely connected, forming an integral sealing area, so that the cold air flowing out of the storage space 210 cannot be deposited at the cabinet opening 300.

[0075] At the same time, external air cannot enter the cabinet opening 300 and accumulate because there is no gap between adjacent sealing components 500. Therefore, it can effectively avoid the internal cold air flow and the external hot air flow from converging at the gap between the sealing components 500 to produce condensation, thereby solving the problem of local condensation and improving user experience.

[0076] In some embodiments of the present application, a plurality of sealing components 500 are provided and arranged on the cabinet opening 300 or the door liner 410. When the cabinet door 400 is closed, adjacent sealing components 500 are connected by being fitted up and down.

[0077] In some embodiments, multiple sealing components 500 are all installed on the cabinet opening 300 or the door liner 410, and the sealing components 500 are made of the same material. The sealing components 500 on the cabinet opening 300 or the door liner 410 are set to different heights. The heights of the multiple sealing components 500 are set to gradually decrease from the outside to the inside of the cabinet opening 300, or gradually increase from the outside to the inside of the cabinet opening 300.

[0078] When the cabinet door 400 is closed, the door liner 410 and the cabinet opening 300 cooperate to squeeze the sealing component 500 on the cabinet opening 300 or the door liner 410, so that any adjacent sealing components 500 of different heights are connected together up and down to form an integral sealing area with good sealing effect.

[0079] In some embodiments, multiple sealing components 500 are all installed on the cabinet opening 300 or the door liner 410, and sealing components 500 made of materials with different deformation amounts are selected, and the sealing components 500 on the cabinet opening 300 or the door liner 410 are set to have the same height.

[0080] When the cabinet door 400 is closed, the door liner 410 and the cabinet opening 300 cooperate to squeeze the sealing component 500 on the cabinet opening 300 or the door liner 410, so that any adjacent sealing components 500 with different deformation amounts at the same height can be connected together vertically.

[0081] In some embodiments of the present application, a plurality of sealing components 500 are provided and arranged on the cabinet opening 300 or the door liner 410. When the cabinet door 400 is closed, the side surfaces of adjacent sealing components 500 are fitted and connected to each other.

[0082] When installing multiple sealing components 500, all of them are installed on the cabinet opening 300 or the door liner 410, and the sealing components 500 are made of the same material, and the multiple sealing components 500 are set to the same height.

[0083] When the cabinet door 400 is closed, the door liner 410 and the cabinet opening 300 cooperate to squeeze the sealing component 500 on the cabinet opening 300 or the door liner 410, so that the inner and outer sides of the sealing component 500 at the same height are fitted and connected to each other.

[0084] In some embodiments of the present application, a plurality of sealing components 500 are provided, some of the sealing components 500 are arranged on the cabinet opening 300, and some are arranged on the door liner 410. The sealing components 500 arranged on the cabinet opening 300 and the sealing components 500 arranged on the door liner 410 are alternately arranged in sequence from the outside to the inside of the cabinet opening 300. When the cabinet door 400 is closed, adjacent sealing components 500 overlap and fit together up and down.

[0085] In some embodiments, the sealing component 500 on the cabinet opening 300 and the sealing component 500 on the door liner 410 are made of the same material, the sealing component 500 on the cabinet opening 300 is set to the same height, and the sealing component 500 on the door liner 410 is set to another height and the heights are the same.

[0086] The sealing components 500 on the cabinet opening 300 and the sealing components 500 on the door liner 410 are arranged alternately. Since the sealing components 500 on the cabinet opening 300 and the sealing components 500 on the door liner 410 are at different heights, the sealing components 500 on the adjacent cabinet openings 300 and the sealing components 500 on the door liner 410 are not flush.

[0087] At this time, when the cabinet door 400 is closed, the sealing component 500 at the cabinet opening 300 and the sealing component 500 on the door liner 410 will overlap and fit together, and any adjacent sealing components 500 of the multiple sealing components 500 will overlap and fit together, thereby realizing a fitting connection of the multiple sealing components 500.

[0088] In some embodiments, the sealing component 500 on the cabinet opening 300 and the sealing component 500 on the door liner 410 are in a flush state, but the sealing component 500 on the cabinet opening 300 and the sealing component 500 on the door liner 410 have different deformation amounts. When the cabinet door 400 is closed, the difference in deformation amounts of the sealing components 500 with different deformation amounts is used to achieve the upper and lower overlapping and fitting of the sealing components 500 on the cabinet opening 300 and the door liner 410.

[0089] In some embodiments of the present application, a plurality of sealing components 500 are provided, some of the sealing components 500 are arranged on the cabinet opening 300, and some are arranged on the door body. The sealing components 500 arranged on the cabinet opening 300 and the sealing components 500 arranged on the door body are alternately arranged in sequence from the outside to the inside of the cabinet body 100. When the cabinet door 400 is closed, the sides of adjacent sealing components 500 are fitted and connected to each other.

[0090] In some embodiments, the sealing component 500 on the cabinet opening 300 and the sealing component 500 on the door liner 410 are made of the same material, and the sealing components 500 installed in the two are in a flush state. After the cabinet door 400 is closed, the inner and outer sides of the sealing component 500 on the cabinet opening 300 and the sealing component 500 on the door liner 410 are fitted and connected.

[0091] In some embodiments, a plurality of sealing components 500 are provided, some of the sealing components 500 are arranged on the cabinet opening 300, and some are arranged on the door body, and the sealing components 500 are made of the same material.

[0092] The plurality of sealing components 500 on the door liner 410 are at a certain height, and the plurality of sealing components 500 on the door liner 410 are arranged adjacent to each other in sequence, forming a group of sealing components 500 of the door liner 410;

[0093] The plurality of sealing components 500 on the cabinet opening 300 are at another height, and the plurality of sealing components 500 on the cabinet opening 300 are arranged adjacent to each other in sequence to form a cabinet opening 300 sealing component 500 group.

[0094] When the cabinet door 400 is closed, adjacent side surfaces of the sealing component 500 on the door liner 410 are fitted and connected to each other, adjacent side surfaces of the sealing component 500 on the cabinet opening 300 are fitted and connected, and the sealing components 500 on the door liner 410 and the sealing components 500 on the cabinet opening 300 at adjacent positions of the sealing component 500 group of the door liner 410 and the sealing components 500 group of the cabinet opening 300 overlap and fit together.

[0095] When arranging, arrange the sealing components 500 of the door liner 410 on the outside, and arrange the sealing components 500 of the cabinet opening 300 on the inside;

[0096] Alternatively, the sealing component 500 group of the door liner 410 is arranged on the inner side, and the sealing component 500 group of the cabinet opening 300 is arranged at the outer side.

[0097] In some embodiments of the present application, the cabinet opening 300 includes: a first cabinet opening portion 310 formed on the outer circle of the cabinet opening 300;

[0098] The door liner 410 is formed with a cabinet opening matching portion 411 arranged corresponding to the position of the first cabinet opening portion 310 . When the cabinet door 400 is closed, the cabinet opening matching portion 411 of the door liner 410 is attached to the first cabinet opening portion 310 .

[0099] The sealing component 500 is disposed on the first cabinet opening portion 310 and / or the cabinet opening matching portion 411 .

[0100] The plurality of sealing components 500 may be disposed on the first cabinet opening portion 310 , or disposed on the cabinet opening 300 , or partially disposed on the first cabinet opening portion 310 and partially disposed on the cabinet opening matching portion 411 .

[0101] In some embodiments, the first cabinet opening portion 310 is a main body portion constituting the cabinet opening 300 , and a top surface thereof is a main body plane of the cabinet opening 300 with a larger area.

[0102] When multiple sealing components 500 are arranged on the cabinet opening matching part 411 and / or the first cabinet opening part 310, when the cabinet door 400 is closed, the multiple sealing components 500 can be connected in sequence and completely spread out on the first cabinet opening part 310 constituting the main body of the cabinet opening 300.

[0103] The first cabinet opening portion 310 is a plane with a relatively large area. After the sealing component 500 is fitted and connected, the first cabinet opening portion 310 is completely sealed, so that the internal air cannot be deposited above the first cabinet opening portion 310 of the cabinet opening 300. At the same time, the external air flow cannot enter the first cabinet opening portion 310 and intersect with the internal cold air, thereby effectively avoiding the problem of condensation caused by the intersection of internal and external airflows due to the existence of gaps between adjacent sealing components 500.

[0104] In some embodiments of the present application, the cabinet opening matching portion 411 includes a first matching portion 4111;

[0105] and a second matching portion 4112 extending downwardly from the first matching portion 4111;

[0106] The first matching portion 4111 is a first matching section formed on the door liner 410, and a first matching surface is formed at the bottom of the first matching section;

[0107] The second matching portion 4112 is a second matching segment, which is connected to the first matching segment via the connecting segment 4115 , and a second matching surface is formed at the bottom of the second matching segment.

[0108] The plurality of sealing components 500 are partially embedded in the first matching portion 4111 , and partially embedded in the first cabinet opening portion 310 or the second matching portion 4112 which is located opposite to the second matching portion 4112 .
