[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. 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.

[0060] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0061] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0062] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0063] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0064] refer to Figure 1-Figure 4The present application provides a refrigeration device, mainly referring to a refrigerator, which includes a box body, and the box body includes an outer shell 100 and an inner shell 200. The outer shell 100 and the inner shell 200 are both shell structures.

[0065] The outer shell 100 is arranged on the outer side of the inner shell 200. A refrigeration chamber is formed in the inner shell 200. The refrigeration chamber may be a refrigerator chamber or a freezer chamber for storing items to be refrigerated.

[0066] An insulating inner cavity is formed between the outer shell 100 and the inner liner 200 for filling with insulating materials. The insulating materials are used to insulate the inner liner 200 and reduce the transfer of cold.

[0067] A food introduction port is formed at the front end of the box body, and the food introduction port is opened and closed through the door body.

[0068] A control box 400 is installed in the inner tank 200. The control box 400 is the control center of the refrigerator and is responsible for monitoring and controlling the temperature, humidity and other parameters of the cold refrigeration chamber.

[0069] The control box 400 contains various sensors and circuit boards, through which it can sense the temperature changes inside the refrigeration chamber and control the refrigeration and defrosting of the refrigeration chamber and the freezer chamber according to the set temperature requirements.

[0070] The control box 400 also has some other functions, such as controlling the lighting of the refrigerator, adjusting the speed of the fan, monitoring the open and close status of the door, etc. It can also communicate with the display screen and control panel of the refrigerator, so that the user can easily adjust the settings and modes of the refrigerator.

[0071] In order to prevent the control box 400 from occupying the space of the refrigeration chamber, a mounting position 230 extending toward the outer shell 100 is formed on the side wall of the inner liner 200 . In the use state, the control box 400 is installed in the mounting position 230 .

[0072] During the manufacturing process of the refrigerator, a tooling part 300 is preset in the installation position 230. The tooling part 300 is used to provide support for the installation position 230 to avoid pressure on it when the insulation material is filled in the insulation cavity, causing the size of the installation position 230 to be deformed, affecting the subsequent assembly of the control box 400.

[0073] Specifically, after the inner liner 200 and the outer shell 100 are installed, the insulation material is filled into the insulation inner cavity through a foaming mold. The insulation material is specifically a foaming material. After being filled into the insulation inner cavity, it can expand rapidly and fill the insulation inner cavity, forming an insulation layer on the outside of the inner liner 200 to avoid the transfer of cold in the inner liner 200.

[0074] refer to Figure 3 , Figure 5 , Figure 6The outer shell 100 is a shell structure with an opening on the front side. The inner shell 200 includes a body 210 and a connecting outer edge 220 formed on the periphery of the body 210 . The connecting outer edge 220 is connected to the front side of the outer shell 100 and fixed on the outer shell 100 .

[0075] The size of the mounting position 230 on the inner liner 200 is adapted to the control box 400 to provide a stable support for the mounting position 230 and prevent it from being deformed.

[0076] The tooling piece 300 is also formed with a conformal surface that matches the inner wall of the installation position 230 . The tooling piece 300 is configured to be fixed in the installation position 230 when the insulation material is filled into the insulation inner cavity to prevent the installation position 230 from being deformed.

[0077] In order to save materials and reduce costs, the tooling piece 300 is designed to be in a shell shape while ensuring the structural strength of the tooling piece 300 .

[0078] In some embodiments of the present application, the tooling part 300 includes a limiting portion 310 and an overlapping portion 320 . The overlapping portion 320 is an outer edge structure formed on the periphery of the limiting portion 310 and bent outward, and the conformal surface is formed on the outer side of the limiting portion 310 .

[0079] An installation opening is formed on the installation position 230 , and the tooling piece 300 and the control box 400 are both connected to the installation position 230 from the installation opening.

[0080] The size of the overlapping portion 320 is larger than the outer peripheral size of the mounting opening on the mounting position 230 , and a connecting recess 233 is formed on the peripheral side of the mounting opening, and the connecting recess 233 is formed on the inner liner 200 .

[0081] In the installed state, the limiting portion 310 extends into the installation position 230, and the overlapping portion 320 is connected to the connecting recess 233 on the peripheral side of the installation opening.

[0082] In order to avoid damage to the inner liner 200 , mechanical connections such as screws are avoided as much as possible between the tooling 300 and the inner liner 200 , and connecting holes are avoided from being opened on the inner liner 200 to affect the insulation and structural strength of the inner liner 200 .

[0083] refer to Figure 1 In some embodiments of the present application, the tooling piece 300 is detachably connected to the mounting position 230 by gluing.

[0084] After the tooling piece 300 is placed in the installation position 230 , the tooling piece 300 is fixed on the installation position 230 by gluing with adhesive strips.

[0085] The adhesive strip is an adhesive structure with a certain width. An adhesive strip is respectively provided on the upper and lower sides of the tooling piece 300 to adhere and fix the tooling piece 300 .

[0086] After the warm material injection molding is completed, the adhesive portion is disassembled, so that the tooling piece 300 is removed from the installation position 230, which is convenient for the subsequent assembly of the control box 400.

[0087] refer to Figure 7-Figure 11 In some other embodiments of the present application, a snap portion 312 is formed on the limiting portion 310, and a snap connection portion 232 adapted to the position of the snap portion 312 is formed on the inner wall of the mounting position 230, and the tooling 300 can be detachably installed in the mounting position 230 by snap connection.

[0088] refer to Fig. 9 The buckle portion 312 is a convex portion formed on the outer wall of the limiting portion 310 and extending outward, and the clamping portion 232 is a concave portion formed on the side wall of the installation position 230 and extending inward.

[0089] During installation, as the limiting portion 310 is installed, the buckle portion 312 is correspondingly engaged with the engaging portion 232 , so that the tooling component 300 is engaged with the installation position 230 .

[0090] After the warm material injection molding is completed, the tooling piece 300 is moved outward, the buckle portion 312 is disengaged from the clamping portion 232, and the tooling piece 300 is removed from the installation position 230, so as to facilitate the subsequent assembly of the control box 400.

[0091] Combination Figure 5 The control box 400 is fixed to the connection recess 233 by fastening screws or other fasteners. The connection recess 233 is formed with a connection hole. The fastening screws fix the control box 400 to the connection hole to fix the control box 400.

[0092] Since the control box 400 requires an external power supply and realizes signal transmission, an external wiring harness is required, and the wiring harness includes wires for providing power to the control box 400 and signal wires connected to the display component and the like.

[0093] One end of the wiring harness is connected to a power source or a display component, and the other end extends from the mounting position 230 to the inner side of the inner tank 200 to be connected to the control box 400 .

[0094] Combination Fig.10 A wiring hole 231 is formed on the mounting position 230, and a wire passing hole 311 is formed on the side wall of the limiting portion 310. The wire passing hole 311 is adapted to the position of the wiring hole 231 for the wiring harness to pass through.

[0095] The wire-passing hole 311 may be a through-hole structure or a cutout formed on the side wall of the limiting portion 310 .

[0096] In the traditional way, after the wire harness passes through the installation position 230, it hangs freely in the inner liner 200. During the filling process of the insulation material, the foaming mold may squeeze the wire harness, causing deformation and damage to the wire harness, affecting the operation of the control box 400.

[0097] In some embodiments of the present application, a protective cavity is formed in the tooling piece 300 , and the wire harnesses passing through the wiring holes 231 and the wire passing holes 311 are collected in the protective cavity.

[0098] The protective cavity is formed in the limiting portion 310 , and the upper part of the protective cavity is at least partially covered by the overlapping portion 320 . After the wiring harness is output from the wiring hole 231 and the wire passing hole 311 , it is collected in the protective cavity.

[0099] refer to Figure 7 In some embodiments of the present application, at least one support portion 240 is formed on the side wall of the refrigeration chamber along the height direction, each support portion 240 includes two support protrusions relatively arranged on both sides of the refrigeration chamber, each support protrusion is constructed to be arranged along the depth direction of the refrigeration chamber, and a support groove 241 is formed on each support protrusion.

[0100] Each supporting protrusion may be a continuous integral structure extending along the depth direction of the refrigeration chamber or may be composed of a plurality of discontinuous parts.

[0101] Combination Fig.13 A supporting shelf 250 is provided on each supporting portion 240 , and both ends of the supporting shelf 250 are movably installed in the corresponding supporting groove 241 , and the supporting shelf 250 moves back and forth along the supporting groove 241 , which is convenient for users to clean.

[0102] In some embodiments of the present application, an installation cavity is further formed between the outer shell 100 and the inner shell 200 . The installation cavity is located at the lower side of the inner shell 200 and is used to install a refrigeration system.

[0103] The refrigeration system includes a compressor, a condenser and a refrigeration circuit (not shown). The refrigeration circuit is connected between the condenser and the compressor and arranged on the back side of the inner tank 200 to provide cooling to the refrigeration chamber.

[0104] The refrigeration circuit is also a freezing circuit, which includes a freezing capillary tube and a freezing evaporator connected to the outlet side of the freezing capillary tube, wherein the freezing capillary tube is connected to the outlet side of the condenser, and the freezing evaporator is connected to the inlet side of the compressor.

[0105] The freezing evaporator is arranged at the rear side of the refrigeration chamber and is used for supplying cold to the refrigeration chamber.

[0106] After the refrigerant enters the condenser from the compressor and is cooled, it enters the freezing capillary tube. After passing through the freezing capillary tube, the refrigerant reaches the freezing evaporator and then returns to the compressor, forming a refrigeration cycle.

[0107] In other embodiments of the present application, a lighting component (not shown) is provided in the inner tank 200. The lighting component is disposed on the supporting shelf 250. The lighting component is in an open state to illuminate the inner tank 200 when the refrigerator door is open, and is in a closed state when the refrigerator door is closed.

[0108] The lighting component in the present application is configured such that when the support shelf 250 is connected in place, the circuit of the lighting component is in an on state, and the lighting component can be switched on and off according to the state of the door body.

[0109] When the supporting shelf 250 is disassembled, the lighting component is in a power-off state, and the lighting component is always in a power-off state and will not be turned on as the door body is opened.

[0110] That is, the lighting element is turned on only when the corresponding supporting shelf 250 is in the connected state and the door of the refrigerator is in the open state.

[0111] When the support shelf 250 is not connected in place or the door of the refrigerator is not opened, the lighting component is in an off state and no lighting action is performed.

[0112] refer to Fig.14 , Fig.15 Specifically, a male end connection part 251 is provided on the rear side of the supporting shelf 250, and a female end connection part 260 is provided on the rear wall of the refrigeration chamber. The female end connection part 260 is connected to the power supply through a line, and the male end connection part 251 is connected to the lighting component line.

[0113] The positions of the male end connection part 251 and the female end connection part 260 are adapted to each other. The male end connection part 251 is connected to or disconnected from the female end connection part 260 as the supporting layer frame 250 moves, so as to facilitate powering on or off of the lighting component.

[0114] A switch is provided on the line between the female end connection part 260 and the power supply. The switch is connected to the control system signal, and the switch state of the door body is also connected to the control system signal.

[0115] When the supporting shelf 250 is in the installed state, the female connecting part 260 and the male connecting part 251 are connected, and the lighting component is connected to the power supply. At this time, when the refrigerated door is opened, the control system controls the switch component to turn on, and the lighting component is powered on. When the door is closed, the control system controls the switch component to turn off, and the lighting component is powered off.

[0116] Specifically, at least one static contact 262 is formed on the female end connection part 260, and at least one moving contact 252 extending toward the rear wall of the refrigeration chamber is formed on the male end connection part 251. In the installed state, the moving contact 252 is in contact and connected with the corresponding static contact 262.

[0117] The male end connection part 251 is formed with an inserting recess that matches the size of the female end connection part 260 , and the female end connection part 260 is detachably connected in the inserting recess.

[0118] The plug-in recess is specifically a groove structure with an opening toward the rear wall of the refrigeration chamber. The female end connection part 260 is plugged into the plug-in recess, which can prevent the liquid formed in the refrigeration chamber from damaging the connection, improve the safety of the connection, and play a waterproof role.

[0119] Furthermore, in order to ensure a tight connection between the stationary contact 262 and the moving contact 252 , an elastic member 261 is disposed between the stationary contact 262 and the female end connecting portion 260 .

[0120] During the connection process between the male end connection part 251 and the female end connection part 260, as the connection deepens, the moving contact 252 and the static contact 262 come into contact, and the elastic member 261 is compressed. The elastic member 261 can improve the tightness of the connection between the moving contact 252 and the static contact 262, thereby avoiding misalignment or separation of the moving contact 252 and the static contact 262, which would affect the power supply of the lighting component.

[0121] The specific disconnection states of the male end connection part 251 and the female end connection part 260 are described in detail below:

[0122] When the supporting shelf 250 is removed from the refrigeration chamber, the male connection part 251 and the female connection part 260 are disconnected. Specifically, the moving contact 252 on the male connection part 251 gradually moves away from the static contact 262 on the female connection part 260 until the moving contact 252 is completely separated from the static contact 262. At this time, the power supply line between the lighting component and the power supply is completely cut off.

[0123] When the support shelf 250 is cleaned or overhauled and installed in the refrigeration room, both ends of the support shelf 250 gradually extend to the rear end of the refrigeration room along the support recesses on the two support portions 240 arranged on the side walls of the refrigeration room. As the support shelf 250 goes deeper, the moving contact 252 on the support shelf 250 gradually approaches the static contact 262 located on the rear wall of the refrigeration room.

[0124] When the moving contact 252 and the static contact 262 begin to contact, the support frame 250 is not fully installed. As the support frame 250 continues to move inward, the elastic member 261 at the other end of the static contact 262 is compressed a certain distance. Under the action of its own elastic force, the elastic member 261 can make the moving contact 252 and the static contact 262 directly contact stably.

[0125] The present application also proposes a refrigeration device, which specifically refers to a refrigerator. The refrigerator includes a box body, and the box body includes an outer shell 100 and an inner shell 200. The outer shell 100 is arranged on the outside of the inner shell 200.

[0126] A refrigeration chamber is formed in the inner liner 200, and the refrigeration chamber can be a refrigerator or a freezer. A heat-insulating inner cavity is formed between the outer shell 100 and the inner liner 200, and the heat-insulating inner cavity is used to fill heat-insulating materials.

[0127] A mounting position 230 extending toward the outer shell 100 is formed on the side wall of the inner shell 200 , and the mounting position 230 is used for detachably mounting the control box 400 .

[0128] Before installing the control box 400 , a tooling piece 300 is connected inside the installation position 230 . The tooling piece 300 is configured to provide support to the installation position 230 during the process of filling the thermal insulation material, so as to increase the structural strength of the installation position 230 .

[0129] The tooling piece 300 includes a limiting portion 310 and an overlapping portion 320 . The overlapping portion 320 is an outer edge structure formed on the periphery of the limiting portion 310 and bent outward, and a conformal surface is formed on the outer side of the limiting portion 310 .

[0130] The mounting portion is formed with a mounting opening, and a connecting recess 233 is formed around the mounting opening. The connecting recess 233 is formed on the inner container 200 , and a connecting hole is formed on the connecting recess 233 .

[0131] The setting of the tooling part 300 can be achieved in the following ways:

[0132] Method 1:

[0133] A through hole is formed on the overlapping portion 320 of the tooling piece 300, and the tooling piece 300 is detachably connected to the connecting recess 233 by fasteners. The size of the overlapping portion 320 is larger than the mounting opening on the mounting position 230. In the installed state, the limiting portion 310 extends into the mounting position 230, and the overlapping portion 320 is connected to the connecting recess 233 on the peripheral side of the mounting opening.

[0134] Method 2:

[0135] In order to improve the structural strength of the tooling piece 300 , the tooling piece 300 is designed to be a solid structure, on which a wire storage chamber is formed, and the opening position of the wire storage chamber corresponds to the routing hole 231 on the hole installation position 230 .

[0136] The wiring harness for connecting with the control box 400 is stored in the wiring storage chamber through the wiring hole 231 to prevent the foaming mold from damaging it.

[0137] Method 3:

[0138] The tooling piece 300 is detachably connected to the mounting position 230 via a snap-fit ​​connection. A snap-fit ​​portion 312 is formed on the limiting portion 310, and a snap-fit ​​portion 232 adapted to the position of the snap-fit ​​portion 312 is formed on the inner wall of the mounting position 230. The tooling piece 300 is detachably installed in the mounting position 230 via a snap-fit ​​connection.

[0139] The buckle portion 312 is a convex portion formed on the outer wall of the limiting portion 310 and extending outward, and the engaging portion 232 is a concave portion formed on the side wall of the mounting position 230 and extending inward.

[0140] During installation, as the limiting portion 310 is installed, the buckle portion 312 is correspondingly engaged with the engaging portion 232 , so that the tooling component 300 is engaged with the installation position 230 .

[0141] After the warm material injection molding is completed, the tooling piece 300 is moved outward, the buckle portion 312 is disengaged from the clamping portion 232, and the tooling piece 300 is removed from the installation position 230, so as to facilitate the subsequent assembly of the control box 400.

[0142] The refrigeration equipment involved in the present application has a tooling piece 300 detachably connected to the mounting position 230 of the inner liner 200. The tooling piece 300 supports the mounting position 230 on the inner liner 200. During the process of filling the insulation material into the insulation cavity, the tooling piece 300 can effectively prevent the mounting position 230 from being deformed, thereby improving the structural strength of the mounting position 230.

[0143] After the insulation material is filled and formed, the tooling 300 is removed from the installation position 230, and then the control box 400 is fixed in the installation position 230;

[0144] The tooling piece 300 can be reused in different refrigeration equipment, which can prevent the inner liner 200 from being deformed due to the extrusion of the thermal insulation material during the foaming process and prevent the assembly size from changing.

[0145] In addition, during the foaming process, the wiring harness can also be collected in the tooling part 300 to avoid being squeezed by the mold during the foaming process, which may cause deformation and damage to the wiring harness.

[0146] 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.

[0147] 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.
