[0051] The refrigerator 100 provided in the embodiment of the utility model can have various implementation forms. Figures 1 to 10 This is a specific implementation of the refrigerator 100 of the utility model. In this embodiment, the refrigerator 100 includes a box body 10, a door body 20 and a power box 30.

[0052] The directions described in the text are based on the direction in which the user faces the refrigerator 100, wherein the left and right sides are distinguished by the direction in which the user faces the refrigerator 100, the side facing the user when the refrigerator 100 is in use is defined as the front side, and the side opposite thereto is defined as the rear side, and the upper and lower sides of the refrigerator 100 when generally working normally are defined to distinguish the up and down.

[0053] like Figure 1 As shown, the box body 10 is used to form the overall appearance of the refrigerator 100. The box body 10 is roughly in the shape of a rectangular parallelepiped frame. The top of the box body 10 and the bottom of the box body 10 are opposite ends. From the top of the box body 10 to the bottom of the box body 10 is the height direction of the box body 10. The left side of the box body 10 and the right side of the box body 10 are opposite sides. From the left side of the box body 10 to the right side of the box body 10 is the width direction of the box body 10. The front side of the box body 10 and the rear side of the box body 10 are opposite sides. From the front side of the box body 10 to the rear side of the box body 10 is the thickness direction of the box body 10. The box body 10 includes a box shell 11 and an inner liner 12. The inner liner 12 is arranged in the box shell 11, and an installation space is formed between the two, which is used to install other component structures of the refrigerator 100 and form a foam insulation layer. A refrigeration chamber 15 is provided inside the inner tank 12. The refrigeration chamber 15 is used to place goods. The refrigeration chamber 15 has a chamber opening, and the chamber opening direction is arranged toward the front side of the box body 10. The refrigeration chamber 15 can be in a refrigerated temperature environment, a frozen temperature environment, or a normal temperature environment. A door body 20 is provided at the chamber opening. The door body 20 is arranged in a straight plate shape at the front side of the box body 10. The door body 20 can be connected to the box body 10 in an openable and closable manner to open or close the refrigeration chamber 15.

[0054] It can be understood that the refrigerator 100 also includes a refrigeration system (not shown) and an air supply system (not shown), and the refrigeration system and the air supply system are electrically connected to a power supply component, and the power supply component is used to supply electricity to each component of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0055] The refrigeration system is installed in the box 10, and the refrigeration system is used to provide cold air to the refrigeration chamber 15. The refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device, and a refrigerant. Each component is distributed at different positions of the box 10 according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process and an evaporation process. The compression process is: after the power cord of the refrigerator 100 is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor of normal temperature and high pressure, and is cooled to a saturated refrigerant liquid. The throttling process is as follows: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device, where it is throttled and depressurized, and the refrigerant becomes wet steam at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat for gasification, which lowers the temperature of the evaporator and its surroundings, achieving refrigeration, and turning the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor, and the above process is repeated. Energy conversion is performed through the change in the state of the refrigerant, and the heat in the refrigerator 100 is transferred to the air outside the box, thereby achieving the refrigeration cycle of the refrigerator 100.

[0056] The air supply system is installed in the box 10 to provide power for the flow of cold air; the air supply system generally includes a fan and an air supply duct defined in the box 10. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan; in other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box 10 is also defined to form an air duct cavity, which is connected to the air supply duct and the refrigeration chamber 15 respectively, so that the air supply duct is connected to the refrigeration chamber 15 through the air duct cavity; it should be noted that the inner liner 12 is provided with an air outlet, which is used to connect the air duct cavity and the refrigeration chamber 15. The cold air generated by the refrigeration system enters the air duct cavity through the air supply duct through the operation of the fan, and flows from the air outlet to the refrigeration chamber 15 to cool the refrigeration chamber 15. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall of the inner liner 12 on the side opposite to the opening of the refrigeration chamber 15 or on the side wall of the inner liner 12 on the side adjacent to the opening of the refrigeration chamber 15; it should also be noted that the refrigeration system and the air supply system belong to common knowledge in the field and will not be described in detail here.

[0057] In the refrigerator 100, if Figures 1 to 10As shown, the power box 30 is installed on the box shell 11. The power box 30 is used to accommodate power distribution components. The power box 30 is pre-fixed on the box shell 11, and a foaming process will be performed later to fix the power box 30 to the box shell 11. The power box 30 includes an end panel 31, a side panel 32, and a bottom shell plate 33. The end panel 31 abuts against the side of the box shell 11 away from the inner liner 12, and the end panel 31 is the main component for the power box 30 to be connected with the box shell 11; the side panel 32 is connected to the end panel 31, the side panel 32 passes through the box shell 11, and the side panel 32 extends toward the inside of the box shell 11; the bottom shell plate 33 is arranged on the side of the side panel 32 away from the end panel 31. Among them, an embedding groove 311 is arranged on the end panel 31, and the embedding groove 311 is arranged in the shape of an annular groove on the side of the end panel 31 close to the box shell 11. The embedding groove 311 is provided with a sealing gasket 315, which is clamped between the end panel 31 and the box shell 11, and extends along the periphery of the end panel 31. The sealing gasket 315 is clamped between the end panel 31 and the box shell 11, and the fitting clearance between the power box 30 and the box shell 11 is absorbed by the deformation of the sealing gasket 315, thereby avoiding the foaming leakage at the joint position of the power box 30 and the box shell 11 during the foaming process; and because the sealing gasket 315 is embedded in the embedding groove 311, the deformation amount of the sealing gasket 315 to the outside can be reduced, thereby improving the tightness of the sealing gasket 315, further reducing the probability of foaming leakage, and improving the qualified rate of the product.

[0058] Furthermore, a mounting opening 115 is provided at the top of the box shell 11, and the mounting opening 115 penetrates the box shell 11. The shape of the mounting opening 115 corresponds to the shape of the power box 30, and the mounting opening 115 is used for embedding and installing the power box 30. It can be understood that the mounting opening 115 can also be provided on other sides of the box shell 11, and it is sufficient to ensure that a position for embedding the power box 30 is provided on the box shell 11, and the specific opening position of the mounting opening 115 is not limited.

[0059] Furthermore, the power box 30 is installed on the top of the box shell 11. The end panel 31 abuts against the outer wall of the box shell 11 to locate the installation position of the power box 30. The end panel 31 is an annular plate structure, and the end panel 31 is arranged around the outside of the installation opening 115. The embedding groove 311 is an annular groove shape and is arranged on the side of the end panel 31 close to the box shell 11. The embedding groove 311 corresponds to the shape of the end panel 31, and the embedding groove 311 is arranged around the outside of the installation opening 115. The sealing gasket 315 is an annular strip structure, and the sealing gasket 315 is an elastic soft part. The sealing gasket 315 is embedded in the embedding groove 311. The sealing gasket 315 is used to seal the joint position between the end panel 31 and the box shell 11, thereby preventing foaming and leakage.

[0060] Furthermore, the side panel 32 extends from the inner diameter of the end panel 31 toward the inside of the box shell 11, and the side panel 32 is inserted into the installation opening 115. The bottom shell plate 33 is arranged on the side of the side panel 32 away from the end panel 31, and the bottom shell plate 33 is generally in the shape of a straight plate. The bottom shell plate 33 covers one side of the side panel 32, and the extension plane of the bottom shell plate 33 is parallel to the extension plane of the end panel 31. The bottom shell plate 33, the side panel 32 and the end panel 31 are enclosed to form a chamber to accommodate power distribution components. In this embodiment, the bottom shell plate 33, the side panel 32 and the end panel 31 are integrated to improve the load-bearing performance of the power box 30.

[0061] Further, the side panel 32 is provided with a twist buckle 321. The twist buckle 321 is provided on one side of the side panel 32 in the first direction. The twist buckle 321 is convexly provided on the outer side of the side panel 32 in a long strip shape. The twist buckle 321 and the end panel 31 are arranged at intervals so that the box shell 11 can be inserted between the twist buckle 321 and the end panel 31. In this embodiment, the twist buckle 321 is provided with a guide surface 3215. The guide surface 3215 is provided at one end of the twist buckle 321 away from the side panel 32. The guide surface 3215 is inclined in a direction from the end away from the side panel 32 to the end close to the side panel 32 in a shape of gradually approaching the end panel 31. The guide surface 3215 is provided to facilitate the insertion of the box shell 11 between the twist buckle 321 and the end panel 31, and at the same time, provide the space required for flipping the power box 30 after the box shell 11 is inserted.

[0062] Further, the side panel 32 is provided with a snap-fit ​​buckle 322. The snap-fit ​​buckle 322 and the twist buckle 321 are arranged on both sides of the side panel 32 opposite to each other, that is, the snap-fit ​​buckle 322 and the twist buckle 321 are arranged on both sides of the side panel 32 in the first direction, respectively. The snap-fit ​​buckle 322 is used to fix the flipped power box 30 on the box shell 11, and then the power box 30 is fixed by the snap-fit ​​buckle 322 and the twist buckle 321. In this embodiment, the side panel 32 is provided with a mounting groove 325 at a position corresponding to the snap-fit ​​buckle 322. The snap-fit ​​buckle 322 is arranged in the mounting groove 325 to provide a space required for deformation during the snap-fitting process of the snap-fit ​​buckle 322 and the box shell 11. It can be understood that the mounting groove 325 can be directly opened on the side panel 32 in the shape of a groove, or a convex strip in the same extending direction as the side panel 32 can be arranged on the outer side of the side panel 32, and the mounting groove 325 runs through the convex strip. The function of the mounting groove 325 here is to provide the space required for the snap buckle 322 to produce elastic deformation, and there is no restriction on whether the mounting groove 325 adopts a through structure, or whether it is set on the side panel 32 or on the convex strip. It should be noted that if the mounting groove 325 is directly opened on the side panel 32, a through structure cannot be used to communicate with the inside of the power box 30, so as to avoid the foam from leaking from the mounting groove 325 into the power box 30 during the foaming process.

[0063] Further, the snap-fit ​​buckle 322 includes a connecting portion 3221, an elastic portion 3222, an extending portion 3223 and a supporting portion 3224. The two ends of the connecting portion 3221 are connected to the inner walls of the two sides of the mounting groove 325, the connecting portion 3221 is in a strip shape and extends along the second direction, and the two ends of the connecting portion 3221 are both connected and fixed to the inner wall of the mounting groove 325. The elastic portion 3222 is in a strip shape and extends from the connecting portion 3221 to the end panel 31. The extension part 3223 is arranged at one end of the elastic part 3222 away from the connecting part 3221. The extension part 3223 is arranged to be gradually close to the embedding groove 311 along the direction of the elastic part 3222 toward the end panel 31. The extension part 3223 is extended obliquely to facilitate the engagement of the snap button 322 with the box shell 11, that is, the box shell 11 pushes the extension part 3223 to move during the engagement until the box shell 11 slides between the snap button 322 and the end panel 31. The top holding part 3224 is arranged at one side of the extension part 3223 close to the end panel 31. The top holding part 3224 is arranged in parallel with the end panel 31. The top holding part 3224 is used to abut against the box shell 11 to increase the abutting area of ​​the snap button 322 with the box shell 11, thereby improving the reliability of the snap button 322 engaging the box shell 11. In this embodiment, a cushion block 316 is arranged in the embedding groove 311. The gasket 316 is arranged in the embedding groove 311 in the shape of a convex block. The setting position of the gasket 316 corresponds to the setting position of the snap buckle 322. The gasket 316 protrudes from the embedding groove 311 toward the snap buckle 322. By setting the gasket 316, the local pressure on the sealing gasket 315 is increased after the box shell 11 is inserted between the snap buckle 322 and the end panel 31, thereby improving the sealing performance of the sealing gasket 315 at the position of the snap buckle 322, and at the same time improving the stability of the snap connection between the snap buckle 322 and the box shell 11.

[0064] Furthermore, the twist buckles 321 are arranged in multiple numbers, each twist buckle 321 is arranged on the same side of the side panel 32, and each twist buckle 321 is arranged at intervals along the side wall of the side panel 32; the number of the snap buckles 322 is the same as the number of the twist buckles 321, and each snap buckle 322 is arranged on the side of the side panel 32 away from the twist buckle 321, and each snap buckle 322 is arranged one by one with each twist buckle 321 on both sides of the side panel 32 in the first direction. By arranging the twist buckles 321 and the snap buckles 322 in a one-to-one correspondence, the reliability of the connection between the power box 30 and the box shell 11 is improved, and at the same time, the force distribution on both sides of the power box 30 is ensured to be balanced, the deformation of the power box 30 is reduced as much as possible, and the sealing performance of the sealing gasket 315 at the joint position between the power box 30 and the box shell 11 is improved.

[0065] Furthermore, a fixing buckle 323 is also provided on the side panel 32. The fixing buckle 323 is provided on one side of the side panel 32 close to the embedding groove 311, and is used to press and clamp the box shell 11. In this embodiment, the fixing buckle 323 includes an expansion portion 3231 and a hooking portion 3232. The expansion portion 3231 is in the shape of a long strip, and one end of the expansion portion 3231 close to the bottom shell plate 33 is connected to the side panel 32. The expansion portion 3231 is inclined along the bottom shell plate 33 toward the end panel 31 and gradually approaches the embedding groove 311. The expansion portion 3231 is elastically set on the side panel 32 by the inclined setting. During the clamping process of the box shell 11, the box shell 11 pushes the expansion portion 3231 to move toward the side panel 32 until the box shell 11 passes through the fixing buckle 323, and then the expansion portion 3231 restores its deformation, clamping the box shell 11 between the fixing buckle 323 and the end panel 31 for clamping. The hook portion 3232 is arranged at one end of the expansion portion 3231 close to the end panel 31, and the hook portion 3232 extends from the expansion portion 3231 toward the side panel 32. The hook portion 3232 is used to increase the contact area between the fixing buckle 323 and the box shell 11, thereby improving the stability of the fixing buckle 323 clamping to the box shell 11.

[0066] Further, the fixing buckles 323 are provided in plurality, and each fixing buckle 323 is arranged at intervals around the side panel 32 to improve the stability of the connection between the power box 30 and the box shell 11. In this embodiment, the fixing buckles 323 are symmetrically arranged on both side surfaces of the side panel 32 in the second direction.

[0067] The utility model also discloses a refrigerator 100, comprising a box body 10, a door body 20 and a power box 30. The box body 10 comprises a box shell 11 and an inner liner 12, the inner liner 12 is arranged in the box shell 11, and a refrigeration chamber 15 is arranged inside the inner liner 12. The door body 20 is connected to the box body 10 to open or close the refrigeration chamber 15. The power box 30 is installed on the box shell 11; the power box 30 comprises an end panel 31, a side panel 32 and a bottom shell plate 33; the end panel 31 abuts against a side of the box shell 11 away from the inner liner 12, the side panel 32 passes through the box shell 11, and the bottom shell plate 33 is arranged on a side of the side panel 32 away from the end panel 31. Among them, an embedding groove 311 is provided on the end panel 31, and a sealing gasket 315 is provided in the embedding groove 311; during installation, one side of the power box 30 is connected to the box shell 11, and then the power box 30 is rotated with the side connected to the box body 10 as the axis until the two sides of the sealing gasket 315 are respectively attached to the box shell 11 and the end panel 31. By first connecting one side of the power box 30 to the box shell 11, and then flipping the power box 30, the installation method of flipping ensures that during the installation process of the sealing gasket 315, one side of the sealing gasket 315 is first clamped between the box shell 11 and the end panel 31, and as the power box 30 is flipped, the sealing gasket 315 is gradually clamped, so that the internal stress generated by the sealing gasket 315 during the extrusion process can be effectively discharged, thereby improving the tightness of the two sides of the sealing gasket 315 with the end panel 31 and the box shell 11, avoiding foaming and leakage at the joint position of the power box 30 and the box shell 11, and further improving the yield rate.

[0068] In summary, the embodiment of the utility model provides a refrigerator 100, which has the following beneficial effects:

[0069] By opening an annular embedding groove 311 on the end panel 31 and arranging a sealing gasket 315 in the embedding groove 311, the sealing gasket 315 is clamped between the end panel 31 and the box shell 11, and the sealing gasket 315 absorbs the fitting gap between the power box 30 and the box shell 11. The embedding groove 311 improves the tightness of the sealing gasket 315, thereby avoiding foaming leakage at the joint position of the power box 30 and the box shell 11 during the foaming process, thereby improving the qualified rate of the product.

[0070] By setting a sealing gasket 315 to absorb the fitting clearance between the power box 30 and the box shell 11, it is no longer necessary to precisely control the fitting pressure between the power box 30 and the box shell 11. Therefore, the twist buckle 321 and the snap buckle 322 can be used for fixing, and screw fixing is no longer required. While saving parts, the installation operation is simpler and more convenient, thereby improving assembly efficiency and reducing the cost of the refrigerator 100.

[0071] By arranging the twist buckle 321 and the snap buckle 322 on both sides of the side panel 32 opposite to each other, during installation, the twist buckle 321 is first snapped with the box shell 11, and then the power box 30 is rotated with the side provided with the twist buckle 321 as the axis until the snap buckle 322 is snapped with the box shell 11, thereby completing the snap connection and fixation between the power box 30 and the box shell 11. One side is first fixed and then gradually extends to the other side as it rotates, so the sealing gasket 315 is first clamped and clamped on one side and then gradually extends to the other side, thereby releasing the stress inside the sealing gasket 315, thereby improving the tightness of the two sides of the sealing gasket 315 with the end panel 31 and the box shell 11, further avoiding foaming and leakage at the joint position of the power box 30 and the box shell 11, and improving the product qualification rate.
