[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Specifically, the refrigeration device involved in the present application is a refrigerator, which includes a box body. The refrigeration compartments in the box body include a cold storage compartment and a freezer compartment. The front ends of the cold storage compartment and the freezer compartment are respectively provided with ports for introducing food. The cold storage compartment is used to insure food, and the freezer compartment is used to freeze food.

[0058] An ice-making device is arranged in the box body for making ice cubes needed in daily life.

[0059] The ice-making device includes a water supply assembly and an ice-making assembly. The water supply assembly is installed in the housing 100 and includes a water storage tank and a water supply pipe group connected to the water storage tank.

[0060] The water storage tank is specifically installed in the cold storage room, in an environment where the temperature range inside the box is above 0 degrees to avoid freezing.

[0061] The ice-making assembly is installed in the freezing chamber and connected to the water supply pipe assembly to make ice cubes from the fluid transported from the water supply pipe assembly.

[0062] refer to Figure 1-Figure 4 The present application proposes a refrigeration device, which includes a box body 100, the box body 100 includes an outer shell and an inner shell, an insulation layer is formed between the outer shell and the inner shell, a refrigeration inner cavity is formed in the box body 100, and the refrigeration inner cavity specifically includes a refrigeration cavity and a freezing cavity, which is used to classify and store items to be refrigerated or frozen.

[0063] Ports for introducing food are respectively arranged at the front ends of the refrigerating chamber and the freezing chamber. The refrigerating chamber is used to insure food, and the freezing chamber is used to freeze food. Door bodies 110 are respectively hinged on the front sides of the refrigerating chamber and the freezing chamber for controlling the switch of the ports for introducing food.

[0064] A display device 200 is installed on the door body 110 of the refrigerating chamber. The display device 200 specifically includes a fixing bracket 210 , an adjustment component and a display panel 220 .

[0065] The fixing bracket 210 is detachably connected to the surface of the door body 110 , and the display panel 220 is connected to the fixing bracket 210 via an adjustment assembly.

[0066] The adjustment assembly includes a telescopic member 250 and a rotating member 240 . One end of the telescopic member 250 is connected to the fixed bracket 210 , and the other end is connected to the display panel 220 through the rotating member 240 .

[0067] The display panel 220 can move along a direction perpendicular to the door body 110 or rotate relative to the door body 110 under the action of the adjustment assembly.

[0068] That is, the telescopic member 250 and the rotating member 240 provide support for the display panel 220, and the telescopic member 250 drives the display panel 220 to move closer to or away from the door body 110. The telescopic member 250 is used to meet the user's specific horizontal adjustment of the display panel 220 relative to the door body 110. The user can push or pull the display panel 220 horizontally according to the actual viewing distance requirements.

[0069] The rotating member 240 can adjust the display panel 220 to a preset angle relative to the door body 110, realize multi-directional flip adjustment, and maintain the adjusted angle to adapt to users of different heights and different viewing directions, providing a better user experience.

[0070] refer to Figure 5 , Figure 6 Specifically, in some embodiments of the present application, the telescopic member 250 is a telescopic sleeve, the telescopic member 250 includes a plurality of telescopic units 251, the telescopic member 250 includes a first end 2501 and a second end 2502, the first end 2501 is connected to the fixed bracket 210, and the second end 2502 is connected to the rotating member 240.

[0071] When the telescopic member 250 is in the retracted state, adjacent telescopic units 251 are mutually sleeved. Specifically, the telescopic unit 251 near the second end 2502 is sleeved inside the telescopic unit 251 near the first end 2501, so that the height dimension of the telescopic member 250 after contraction is small, saving storage area.

[0072] In the fully retracted state, the overall height dimension of the telescopic member 250 is the height of a single telescopic unit 251, so as to reduce the distance between the display panel 220 and the door body 110 in the retracted state.

[0073] In the extended state, the telescopic member 250 gradually shrinks along the direction from the first end 2501 to the second end 2502 , that is, the telescopic member 250 is tapered as a whole, so that the telescopic members 250 can be sleeved with each other in the contracted state.

[0074] The material of the telescopic member 250 can be metal, rubber or plastic. After the user applies force, the telescopic member 250 can be extended to a target length within a certain range and maintained at the length, thereby providing support for the display panel 220 .

[0075] The telescopic member 250 can be manually stretched and pushed in. When fully retracted, the telescopic units 251 fit into each other and when stretched, can be extended to different lengths as needed.

[0076] In other embodiments of the present application, the telescopic member 250 may also be configured as an automatically telescopic structure.

[0077] The telescopic member 250 is an electric push rod, and a button for controlling the extension and retraction of the electric push rod is provided on the display panel 220. When the user presses and holds the extension button, the electric push rod extends, and when the user releases the extension button, the electric push rod stops extending.

[0078] Similarly, a shortening button for controlling the shortening of the electric push rod is provided on the display panel 220. When the user long presses the shortening button, the electric push rod shortens. When the shortening button is released, the electric push rod stops shortening.

[0079] refer to Figure 7 , Figure 8 The rotating member 240 is used to rotate the display panel 220 to a target angle after the telescopic member 250 is extended, so as to adapt to different viewing angles of the user.

[0080] The rotating member 240 is a spherical joint, which is similar to a universal joint. After the user applies force, the display panel 220 can be rotated to a preset angle in any direction along the rotating member 240 .

[0081] The specific implementation method of the rotating member 240 is the existing technology, and its working principle is not the design focus of this application, so it will not be elaborated here.

[0082] Specifically, the spherical joint includes a fixed portion 242 and a rotating portion 243 . The fixed portion 242 is connected to the second end 2502 of the telescopic member 250 via a fastener 252 , and the rotating portion 243 is used to connect to the display panel 220 .

[0083] Specifically, a penetrating connecting hole 2422 is formed on the side wall of the fixing portion 242, and a through hole is formed on the second end 2502 of the telescopic member 250. The fastener 252 is a connecting shaft extending along the radial direction of the telescopic member 250. Both ends of the connecting shaft pass through the second end 2502 of the telescopic member 250 and the connecting holes 2422 on the fixing portion 242, respectively, to connect and fix the second end 2502 of the telescopic member 250 and the fixing portion 242.

[0084] After the telescopic member 250 is extended to a certain length, the user can rotate the display panel 220 to avoid interference between the display panel 220 and the door body 110 .

[0085] The rotating portion 243 rotates a target angle relative to the fixing portion 242 , and rotates the display panel 220 to a direction that is convenient for the user to observe.

[0086] In order to improve the integrity of the display device 200 , the display panel 220 is protected.

[0087] refer to Fig.10 A mounting opening 2111 is formed on the fixing bracket 210 . When the telescopic member 250 is in the telescopic state, the display panel 220 is retracted into the mounting opening 2111 , and the outer surface thereof is flush with the front side of the fixing bracket 210 .

[0088] The size of the installation opening 2111 is not smaller than the display panel 220 . When the telescopic member 250 is retracted, the display panel 220 is retracted to the inside of the installation opening 2111 , and the outer surface of the display panel 220 is flush with the outer surface of the fixing bracket 210 .

[0089] Combination Figure 4 The mounting opening 2111 is close to one side of the door body 110 , that is, a support portion is formed on the inner side of the mounting opening 2111 , and a connecting back plate 260 is detachably connected to the support portion, and the first end 2501 of the telescopic member 250 is detachably connected to the connecting back plate 260 .

[0090] Specifically, the support portion includes an upper support portion 214 and a lower support portion 215 formed at the upper and lower ends of the installation opening 2111 . The upper support portion 214 and the lower support portion 215 are support protrusions formed at the upper and lower ends of the installation opening 2111 and extending toward the door body 110 .

[0091] The upper and lower ends of the connecting back plate 260 are respectively connected to the upper supporting portion 214 and the lower supporting portion 215 by welding or other methods, so that an installation inner cavity is formed between the connecting back plate 260 and the installation opening 2111 .

[0092] When the display panel 220 is in the retracted state, the telescopic member 250 and the rotating member 240 are retracted into the installation inner cavity.

[0093] The telescopic member 250 and the connecting back plate 260 are connected and fixed via an adapter 270 .

[0094] refer to Fig.10 , Fig.11 In order to reduce the size of the display device 200 protruding from the door body 110 , the adapter 270 includes an annular adapter ring 271 and connecting beams 272 dispersedly formed on the periphery of the adapter ring 271 .

[0095] Specifically, the connection beams 272 are evenly arranged along the circumference of the adapter ring 271 to improve the stability of the connection.

[0096] A matching surface that matches the outer side of the first end 2501 of the telescopic member 250 is formed on the inner side of the adapter ring 271 , and the matching surface is a conical surface that gradually contracts in a direction away from the door body 110 .

[0097] The first end 2501 of the telescopic member 250 is connected to the mating surface.

[0098] Specifically, the outer wall of the telescopic unit 251 located at the first end 2501 of the telescopic member 250 is connected to the mating surface.

[0099] During installation, the adapter ring 271 is covered on the outside of the telescopic part 250. Since the inner diameter of the adapter ring 271 is compatible with the outer wall size of the telescopic unit 251 at the corresponding position, no additional fixing structure is required on the adapter ring 271 to achieve the connection and fixation between the telescopic part 250 and the connecting back plate 260.

[0100] The adapter 270 and the connecting back plate 260 are detachably connected by mechanical connection.

[0101] Specifically, a fixing hole is formed on each connecting beam 272 , and the connecting beam 272 is detachably connected to the connecting back plate 260 by fastening screws.

[0102] Combination Figure 4 In order to facilitate the connection and fixation between the display panel 220 and the spherical joint, a display back panel 230 is also arranged between the spherical joint and the display panel 220.

[0103] The display panel 220 is pre-connected to the outer side of the display back plate 230 by gluing or other methods.

[0104] The rotating portion 243 is fixed to the display back plate 230 by screw connection, so as to avoid damage to the display panel 220 during the process of fixing the rotating portion 243 and the display panel 220 .

[0105] Under the action of the retractable member 250 and the rotating member 240 , the display back plate 230 and the display panel 220 are retracted and turned synchronously.

[0106] The display back plate 230 is connected to the support portion. A plurality of fixing beams 241 are formed on the rotating portion 243. The fixing beams 241 are provided with fixing holes. The fixing beams 241 are detachably connected to the display back plate 230 by fastening screws.

[0107] The display panel 220 is connected to the housing 100 via a wiring harness to provide the power required during operation.

[0108] refer to Figure 4 , Figure 6 , Figure 8 as well as Fig. 9 Correspondingly, in order to facilitate the passage of the wiring harness and provide protection for the wiring harness, a front threading hole 231 is provided on the display back panel 230, a through threading hole 244 is formed on the rotating member 240, a rear threading hole 261 is formed on the connecting back panel 260, and a through middle channel 253 is formed in the telescopic member 250.

[0109] From front to back, the front wire threading hole 231, the wire threading hole 244, the middle channel 253 and the rear wire threading hole 261 together form a wire threading channel for the wire harness to pass through.

[0110] One end of the wiring harness is connected to the display screen, and the other end passes through the wiring passage and the door body 110 and then is connected to the box body 100.

[0111] refer to Fig. 9 In other embodiments, the fixing bracket 210 includes a front panel 211 and supporting beams 212 formed on both sides of the front panel 211, and the fixing bracket 210 is a sheet metal integrally formed structure.

[0112] The installation opening 2111 is formed on the front panel 211 , and the supporting vertical beams 212 are formed at bends on both sides of the front panel 211 extending toward the door body 110 .

[0113] An inwardly bent portion 213 is formed on the supporting beam 212, and the bent portion 213 is flush with the surface of the door body 110. A fixing hole is formed on the bent portion 213, and the bent portion 213 is connected and fixed to the door body 110 by fastening screws and other structures.

[0114] For the refrigeration equipment involved in the present application, the user can push or pull the display panel 220 horizontally according to the actual viewing distance requirements; the rotating member 240 can adjust the display panel 220 to a preset angle relative to the door body 110, and realize multi-directional flip adjustment to adapt to users of different heights and different viewing directions, thereby providing a better user experience.

[0115] In addition to the above-mentioned display device 200, a drawer is also provided in the freezing chamber of the refrigeration equipment. The drawer can store items by category to facilitate users to take them out.

[0116] At least one set of guide rail components is arranged between the drawer and the inner container. The guide rail components include a fixed guide rail component and a movable guide rail component. The fixed guide rail component extends along the depth direction of the inner container, and the movable guide rail component is movably connected to the fixed guide rail component.

[0117] That is, the fixed guide rail members are arranged in pairs and symmetrically on the two side walls of the inner container.

[0118] Correspondingly, the movable guide rail members are also arranged in pairs and are cooperatively connected to the corresponding fixed guide rail members.

[0119] An air flow channel is arranged between the refrigerating chamber and the freezing chamber, and a fan component is arranged in the air flow channel or in the freezing chamber. When the fan component is turned on, the air flow in the freezing chamber is driven to be transported to the refrigerating chamber through the air flow channel.

[0120] A switch portion is formed in the air flow channel for controlling the switch of the air flow channel.

[0121] Because the freezer produces odor due to long-term storage of frozen food when in use, the odor is blown to the refrigerator compartment with the air flow under the action of the fan and spreads in the refrigerator compartment, causing users to have a bad experience when using the refrigerator compartment, and also causing contamination to other food in the refrigerator compartment.

[0122] In view of the above problems, the present application provides an adsorption assembly and a sensor in the airflow channel, wherein the adsorption assembly includes at least two adsorption members spaced apart in the airflow channel along the flow direction of the airflow.

[0123] A plurality of sensors are respectively arranged at the input end and the output end of each adsorbent, and are used to detect the airflow components before and after flowing through the corresponding adsorbent.

[0124] When the switch is turned on, each sensor monitors the odor concentration.

[0125] When the adsorbent works well, the odor concentration detected by the upstream and downstream corresponding sensors should be greatly reduced, and the difference is large. When the difference is less than the preset value, the controller reminds the user to replace the corresponding adsorbent.

[0126] The difference between the sensors upstream and downstream of each adsorbent is connected to the display panel 220 signal through the controller. The display panel 220 can display the odor concentration difference of the upstream and downstream sensors corresponding to each adsorbent, so as to facilitate the user to observe the working status of the adsorbent in real time, with a higher degree of intelligence.

[0127] 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.

[0128] 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.
