Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a refrigeration device. Background Art

[0002] At present, in the market, when opening the door of a refrigerator, in addition to overcoming the influence of the door's own weight, it is also necessary to overcome the influence of the negative pressure of the refrigerator's refrigeration. Negative pressure is the air in the cabinet that contracts when it is cooled after a long period of refrigeration, causing the air pressure in the cabinet to be significantly lower than that in the outside world, forming a huge pressure difference. In order to avoid the above negative pressure, existing products often adopt the following methods: First, a convex rib is designed on the cabinet, and the soft PNC door seal is partially lifted by the rib to form a gap. When the pressure in the cabinet is lower than that in the outside world, the outside air will enter the box through the gap until the internal and external air pressures reach a balance; second, a groove is designed on the cabinet to directly form a ventilation channel. When the pressure in the cabinet is lower than that in the outside world, the outside air will enter the cabinet through the groove until the internal and external air pressures reach a balance; third, air holes are added to the soft PVC door seal. When the pressure in the box is lower than that in the outside world, the outside air will enter the box through the air holes until the internal and external air pressures reach a balance. The above methods are implemented on the same principle, that is, to achieve air pressure balance by connecting the solid inner liner with the outside world. Therefore, they all have the following problems: as a storage device for frozen food, the freezer has extremely high requirements for sealing and heat preservation during refrigeration; but since negative pressure will only be formed in the freezer box under refrigeration, the above method just destroys the sealing and heat preservation requirements of the freezer; especially in long-term refrigeration state, due to the continuous entry of a large amount of outside air into the refrigeration equipment cabinet, the frost on the inner wall of the box will gradually increase, which will lead to a decrease in the heat transfer efficiency of the evaporator and a decrease in the refrigeration efficiency; the size and number of the air permeable channels directly affect the effect of pressure balance: although too large or too many channels are conducive to the air pressure balance effect, they are not conducive to heat preservation and sealing; too small or too few channels may not be able to achieve the air pressure balance effect, especially if they are too small, due to the large temperature difference between the air inside and outside the box, it is very easy to cause frost and ice blockage in the channels, resulting in ventilation failure; the above-mentioned ribs, grooves or air holes are all located on the visible surface of the appearance, which seriously affects the appearance of the product.

[0003] At present, most refrigerator products on the market use front door handles. Such handles are large in size and protrude from the cabinet body. In daily use, they not only increase the required placement space, but also pose safety hazards such as being touched. At the same time, the door handles will also increase the packaging size of the product, resulting in increased packaging and transportation costs. At present, there are also refrigerator door handles designed to be foldable in the market to save the space occupied by the door handles, but such designs are complex in structure, costly, and difficult to repair.

[0004] Therefore, it is a technical problem to be solved urgently to develop a refrigeration device that will not be affected by negative pressure when the door of the refrigeration device is opened and can be opened smoothly. When the door of the refrigeration device is closed, the air inside the cabinet and outside the cabinet will not circulate, which will not cause a decrease in refrigeration efficiency.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0080] In some embodiments of the present application, a refrigeration device is provided, such as Figures 1 to 12As shown, the refrigeration equipment includes a door body 100 and a cabinet body 200. As a frozen food storage device, the refrigeration equipment has extremely high requirements for sealing and heat preservation during refrigeration; however, since negative pressure is formed in the cabinet body 200 of the refrigeration equipment under refrigeration, the refrigeration equipment needs to overcome not only the influence of the deadweight of the door body 100 but also the influence of the refrigeration negative pressure in the cabinet body 200 during the process of opening the door body 100. The so-called "negative pressure" means that after a long period of refrigeration, the air in the cabinet body 200 contracts when it is cold, causing the air pressure in the cabinet body 200 to be significantly lower than that in the outside, forming a huge pressure difference.

[0081] The door body 100 is connected to the cabinet body 200 in an openable and closable manner. In the process of opening the door body 100 relative to the cabinet body 200, in addition to overcoming the weight of the door body 100, it is also necessary to overcome the effect of the negative pressure in the cabinet body 200 on the door body 100. Therefore, it will cause inconvenience to the user to open the door body 100.

[0082] Therefore, a ventilation passage needs to be formed between the door body 100 and the cabinet body 200 to allow air flow inside and outside the cabinet body 200 to flow, thereby solving the problem of negative pressure inside the cabinet body 200.

[0083] In the existing refrigeration equipment, convex ribs can be provided on the cabinet 200, or grooves can be provided on the cabinet 200, so that the outside air can enter the cabinet 200 through the gap. It is also possible to add air holes on the soft PVC door seal to achieve the circulation of air inside and outside the cabinet 200.

[0084] The above methods are used to solve the problem of negative pressure, all of which achieve air pressure balance by connecting the cabinet 200 with the outside world. However, they all have the following problems:

[0085] As a frozen food storage device, the refrigeration equipment has extremely high requirements for sealing and heat preservation during refrigeration. However, since negative pressure is formed in the refrigeration state, the above method just destroys the sealing and heat preservation requirements of the refrigeration equipment. In particular, in the long-term refrigeration state, since a large amount of external air continuously enters the cabinet 200, the frost on the inner wall of the cabinet 200 will gradually increase, thereby causing the evaporator heat transfer efficiency to decrease and the refrigeration efficiency to decrease.

[0086] The size and number of ventilation channels directly affect the effect of pressure balance: too large or too many channels may help to achieve pressure balance, but are not conducive to thermal insulation and sealing; too small or too few channels may fail to achieve pressure balance. In particular, too small channels may easily be blocked by frost and ice due to the large temperature difference between the air inside the cabinet and the outside world, resulting in ventilation failure.

[0087] The ribs, grooves or air holes mentioned above are all located on the visible surface, which seriously affects the appearance of the product.

[0088] In some embodiments of the present application, a sealing ring 400 is used between the cabinet body 200 and the door body 100 to achieve sealing between the two in a relatively closed state.

[0089] In some embodiments of the present application, Figure 8 , Fig.11 As shown, an inner liner 210 is disposed in the cabinet 200. An airflow passage 110 is formed in the door 100, and one end of the airflow passage 110 is connected to the inner liner 210. The gas in the inner liner 210 can enter into the airflow passage 110.

[0090] A refrigeration chamber is formed in the inner container 210 , and the refrigeration chamber is communicated with the air flow passage 110 .

[0091] In some embodiments of the present application, Figure 2 As shown, the refrigeration device further includes a handle unit 300. The handle unit 300 is connected to the door body 100, and the door body 100 can be opened and closed relative to the cabinet body 200 by pulling the handle unit 300.

[0092] In some embodiments of the present application, when the handle unit 300 is pulled, the airflow passage 110 can be connected to the outside of the cabinet 200, and when the external force on the handle unit 300 is removed, the airflow passage 110 is disconnected from the outside of the cabinet 200. In this state, the problem of negative pressure and the problem of reduced heat transfer efficiency and reduced refrigeration efficiency caused by the airflow passage 110 being always connected to the outside of the cabinet 200 can be solved.

[0093] In some embodiments of the present application, Figure 3 As shown, the handle unit 300 includes a rotating portion 310 , and the rotating portion 310 includes a sealing assembly.

[0094] like Figure 8 As shown, during the process of the rotating portion 310 rotating relative to the cabinet 200 under the action of external force, the sealing component is opened relative to the air flow passage 110. Fig.11 As shown, when the rotating portion 310 rotates to a reset position relative to the cabinet 200 when the external force disappears, the sealing assembly seals the other end of the airflow passage 110 .

[0095] like Figure 8 , Fig.10 As shown, the rotating portion 310 drives the sealing assembly to open and close relative to the airflow passage 110, thereby realizing the opening and closing of the airflow passage 110 in communication with the outside.

[0096] In some embodiments of the present application, Figure 4 , Figure 5 , Figure 6 As shown, the handle unit 300 further includes a fixing portion 320 . The fixing portion 320 is connected to the door body 100 .

[0097] The rotating portion 310 can rotate relative to the fixing portion 320 under the action of an external force.

[0098] The rotating portion 310 rotates relative to the fixed portion to a reset position when the external force disappears.

[0099] The reset position is a state where the rotating portion 310 and the fixing portion 320 are in contact with each other.

[0100] In some embodiments of the present application, Figure 4 , Figure 5 , Figure 6 As shown, a plurality of through holes 321 are formed on the fixing portion 320. Both ends of the through holes 321 are respectively connected to the air flow passage 110 and the outside of the cabinet 200.

[0101] In some embodiments of the present application, the end of the airflow passage 110 communicating with the cabinet 200 is defined as a first end, and the end of the airflow passage 110 communicating with the through hole 321 is defined as a second end.

[0102] Specifically, the cross-sectional area of ​​the through hole 321 is smaller than the cross-sectional area of ​​the second end portion of the airflow passage.

[0103] The through holes 321 pass through the fixing portion 320. A plurality of the through holes 321 are in communication with the air flow passage 110. When the rotating portion 310 rotates to the fixing portion 320, the sealing component abuts against the through holes 321.

[0104] In some embodiments of the present application, Figure 3 As shown, the sealing assembly includes a plurality of sealing columns 3111. The number of the sealing columns 3111 is equal to the number of the through holes 321, and the plurality of sealing columns 3111 are respectively used to seal the plurality of through holes 321.

[0105] In some embodiments of the present application, in order to enable the plurality of sealing columns 3111 to seal the through hole 321, the sealing columns 3111 are used to block the communication between the airflow passage 110 and the airflow outside the cabinet 200. Therefore, the specific structural form of the sealing columns 3111 is not limited, and the sealing columns 3111 can adopt various different structural forms.

[0106] Specifically, the sealing column 3111 may be a cylindrical structure. The through hole 321 may be a cylindrical hole. The end of the sealing column 3111 may be inserted into the through hole 321 to seal the through hole 321 .

[0107] Specifically, the end of the sealing column 3111 may also abut against the end of the through hole 321 , thereby closing the through hole 321 . In this case, the cross-sectional area of ​​the sealing column 3111 is greater than the cross-sectional area of ​​the through hole 321 .

[0108] In some embodiments of the present application, the rotating portion 310 includes a rotating end 311 and an opening and closing end 312. The rotating portion 310 is rotatably connected to the fixed portion 320 via the rotating end 311. When the rotating portion 310 rotates relative to the fixed portion 320, the opening and closing end 312 opens and closes relative to the fixed portion 320.

[0109] The fixing portion 320 is provided with a plurality of first mounting holes, and an equal number of second mounting holes are provided at corresponding positions on the door body 100 . A plurality of fasteners 322 pass through the first mounting holes and the second mounting holes in sequence to achieve a detachable connection between the fixing portion 320 and the door body 100 .

[0110] In some embodiments of the present application, the rotating portion 310 further includes a handle body 313 , a rotating shaft 314 and a reset driving component 315 .

[0111] The rotating end 311 and the opening and closing end 312 are respectively formed at two ends of the handle body 313 .

[0112] Both ends of the rotating shaft 314 are connected to the fixing portion 320 .

[0113] The rotating end 311 of the handle body 313 is rotatably connected to the rotating shaft 314 . The opening and closing end 312 is opened and closed by the rotation of the rotating end 311 relative to the rotating shaft 314 .

[0114] The reset driving component 315 can drive the handle body 313 to rotate relative to the rotation shaft 314 .

[0115] Specifically, the reset driving component 315 includes a torsion spring. The torsion spring is extended along the length direction of the handle body 313.

[0116] The middle portion of the torsion spring is detachably connected to the rotating portion 310 , and the two ends of the torsion spring are detachably connected to the fixing portion 320 .

[0117] Specifically, Fig.12 As shown, the torsion spring includes two end connecting portions 3151 , two torsion spring bodies 3152 , and a middle connecting portion 3153 connected between the two torsion spring bodies 3152 .

[0118] Two plug-in components 323 are provided at corresponding positions of the fixing portion 320 , and plug-in holes are formed on the plug-in components 323 . The two end connection portions 3151 are respectively inserted into the two plug-in components 323 , so that the relative positions between the end connection portions 3151 and the fixing portion 320 are fixed.

[0119] An inserting groove 3131 is formed on the handle body 313 , and the middle end connecting portion 3153 is inserted into the inserting groove 3131 , so that the relative positions of the middle end connecting portion 3153 and the handle body 313 are fixed.

[0120] In some embodiments of the present application, the rotation shaft 314 is used to limit the coaxial rotation of the torsion spring body 3152 and the handle body 313 .

[0121] The two torsion spring bodies 3152 are sleeved outside the rotating shaft 314 , and the torsion spring drives the rotating part 310 to rotate around the rotating shaft 314 relative to the fixed part 320 until it rotates to a reset position.

[0122] Two ends of the rotating shaft 314 are fixedly connected to the fixing portion 320 .

[0123] Two ends of the rotating shaft 314 are rotatably connected to the rotating end 311 of the rotating portion 310 .

[0124] The torsion spring can drive the rotating portion 310 to rotate relative to the fixing portion 320 to a reset position.

[0125] In some embodiments of the present application, Figure 3 , Figure 8 As shown, the opening and closing end 312 of the rotating part 310 is formed with a buckle part 316. A buckle accommodating cavity 317 is formed between the buckle part 316 and the fixed part 320. When the user extends his hand into the buckle accommodating cavity 317, the user applies force at the buckle part 316 to drive the opening and closing end 312 of the handle body 313 to rotate relative to the rotating end 311.

[0126] Specifically, an inclined portion 3121 with an inclined angle that tilts outward is formed at the opening and closing end 312, so that a hand-holding cavity 317 is formed between the inclined portion 3121 and the fixing portion 320 to ensure that the top of the user's finger can be inserted.

[0127] In some embodiments of the present application, shaft holes 318 are respectively formed at both ends of the rotating end 311 of the handle body 313, and the shaft holes 318 are sleeved outside the rotating shaft 314, so that the rotating end 311 can rotate relative to the rotating shaft 314. The two ends of the rotating shaft 314 extend from the two shaft holes 318 and are fixedly connected to the fixing part 320.

[0128] In existing refrigeration equipment products, front door handles are mostly used. Such handles are large in size and protrude from the cabinet body. In daily use, they not only increase the required placement space, but also pose safety hazards such as being touched. At the same time, the door handles will also increase the packaging size of the product, resulting in increased packaging and transportation costs. In the current market, there are also refrigerator door handles designed to be foldable to save the space occupied by the door handles, but such designs are complex in structure, costly, and difficult to repair.

[0129] Therefore, in some embodiments of the present application, the handle unit 300 is extended along the side of the door body 100.

[0130] Specifically, the fixing portion 320 is extended along a side surface of the door body 100 .

[0131] Specifically, when no external force is applied to the rotating part 310, that is, when it is not in use, the rotating part 310 abuts against the fixing part 320, thereby saving the space occupied by the handle unit 300, thereby reducing the overall size of the refrigeration device, saving packaging costs, and reducing damage to the refrigeration device during transportation.

[0132] In some embodiments of the present application, a limit stop portion 319 is further provided on the rotating portion 310 .

[0133] The rotating portion 310 can rotate relative to the fixed portion 320 under the action of an external force. When the rotating portion 310 rotates relative to the fixed portion 320 to an extreme position, the extreme stop portion 319 abuts against the fixed portion 320 .

[0134] During the process of the rotating part 310 rotating relative to the fixed part 320 until the limit stop part 319 abuts against the fixed part, the airflow passage 110 is connected with the outside, so that the airflow in the inner tank 210 in the cabinet body 200 can flow and the negative pressure phenomenon can be alleviated. Then, when the limit stop part 319 and the fixed part 320 are in abutment, the handle body 313 continues to apply force, and the handle body 313 can drive the door body 100 to open relative to the cabinet body 200.

[0135] In some embodiments of the present application, Figure 2 , Figure 8 As shown, the limit stop portion 319 is extended along the rotating end 311 of the handle body 313 .

[0136] There is no limitation on the specific structure of the limit stopper 319 .

[0137] Specifically, the limit stop portion 319 may be a stop boss extending along the length direction of the top of the handle body 313 .

[0138] In some other embodiments, the limit stop portion 319 may also be a plurality of stop protrusions spaced apart along the length direction of the top of the handle body 313 .

[0139] When the handle body 313 drives the limit stopper 319 to rotate to the limit position, the limit stopper 319 abuts against the fixing portion 320 to prevent the handle body 313 from further rotating. Thus, the handle body 313 can more conveniently drive the door body 100 to rotate relative to the cabinet body 200.

[0140] In some embodiments of the present application, before the action of pulling the handle body 313 occurs, the sealing component abuts against the end of the airflow passage 110, ensuring the sealing of the refrigeration chamber in the inner liner 210 of the cabinet 200, thereby ensuring the refrigeration effect in the refrigeration chamber, and avoiding the aggravation of the frost on the inner wall of the inner liner 210 of the cabinet 200 due to the continuous entry of a large amount of external air into the refrigeration chamber under a long-term refrigeration state. Then, the user pulls the opening and closing end 312 of the handle body 313, and the opening and closing end 312 rotates around the rotating end 311. At the same time, the sealing component rotates with the handle body 313, so that the sealing component is separated from the end of the airflow passage 110, so that the airflow passage 110 is opened, one end of the airflow passage 110 is connected to the refrigeration chamber, and the other end of the airflow passage 110 is connected to the atmosphere outside the cabinet 200 in this state, so that the gas outside the cabinet 200 and the gas in the refrigeration chamber can circulate through the airflow passage.

[0141] By setting a cabinet 200, an inner liner 210 is set in the cabinet 200; an airflow passage 110 is formed in the door 100, and one end of the airflow passage 110 is connected to the inner liner 210; by setting a handle unit 300, it can be used to drive the door 100 to open and close relative to the cabinet 200; the handle unit 300 includes a rotating part 310, and the rotating part 310 rotates relative to the cabinet 200 through a rotating end 311. A sealing component is provided on the rotating part 310. When the rotating part 310 rotates relative to the cabinet 200 under the action of an external force, The sealing component is separated from the air flow passage 110, so that the air flow passage 110 is opened, and the gas in the inner tank 210 of the cabinet 200 is exchanged with the air flow outside the cabinet 200 through the air flow passage 110, thereby solving the problem of negative pressure in the inner tank of the cabinet 200. When the external force is removed, the rotating part 310 rotates to the reset position relative to the cabinet 200, and the sealing component re-seals the air flow passage 110 to block the flow of air between the outside of the cabinet 200 and the inside of the cabinet 200, thereby avoiding the problem of reduced refrigeration efficiency and frosting.

[0142] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0143] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
