A car refrigerator is a typical portable refrigerator, which generally refers to a refrigerator that can be installed and used in a vehicle. In addition, some portable refrigerators are equipped with batteries and can be used outside the vehicle. A car refrigerator is a continuation of a household refrigerator, and can use semiconductor electronic refrigeration technology or compressor refrigeration technology.

[0003] At present, the mobile refrigerators on the market have a single function, generally only a refrigeration function. With the gradual development of technology, mobile refrigerators with ice-making functions have also been launched on the market. The ice-making function is set as a functional module in the mobile refrigerator. The ice cubes produced by the ice-making module can be taken out directly by the user and added to the beverage for drinking. Especially in hot summer weather, people hope to drink ice-cold frozen water quickly. The conventional practice is to add ice cubes to drinking water so that the drinking water can be quickly cooled to form frozen water. In this process, cooling takes time and cannot achieve the purpose of direct drinking. It can be seen that the current mobile refrigerators cannot produce frozen water that can be drunk immediately, and it is difficult to meet the use needs. Summary of the invention

[0046] Currently, the mobile refrigerators on the market have a single function, generally only refrigeration function, and some have added ice making function. However, there is no special function to produce direct drinking chilled water. People can only add the produced ice cubes to drinking water and cool it to form chilled water. In this process, cooling takes time and cannot be drunk immediately. The current mobile refrigerators cannot produce direct drinking chilled water and are difficult to meet the needs of use.

[0047] Here, the embodiment of the present application provides a new type of mobile refrigerator and its ice-making device, which redesigns the ice-making module in the mobile refrigerator and integrates the ice-making and chilled water making functions. It can not only make ice cubes but also make chilled water, effectively improving the overall performance of the mobile refrigerator. It is now described in detail.

[0048] Please also read Figure 1 , Figure 2 and Figure 3 A mobile refrigerator includes a cold storage cabinet and an ice making device of the present application. The ice making device includes an ice making mechanism 1, an ice storage box 2, a filter mechanism 3 and a water tank 4.

[0049] The ice storage box 2 is used to store ice cubes, and a leak hole 21 is provided at the bottom of the ice storage box 2. In this embodiment, the ice storage box 2 can preferably be arranged in a drawer type, so that the ice storage box 2 can be directly pulled out or pushed into the mobile refrigerator by the user.

[0050] The ice-making mechanism 1 comprises an ice-maker 11, a water-carrying bag 12 and a driver 13. The ice-maker 11 is arranged on the water-carrying bag 12 and can make ice from the water in the water-carrying bag 12. The output end of the driver 13 is connected to the water-carrying bag 12, and the driver 13 is used to drive the water-carrying bag 12 to flip onto the ice storage box 2, so as to pour the manufactured ice cubes onto the ice storage box 2.

[0051] The water tank 4 is connected to the ice-making mechanism 1 through a pipe 5, on which a water pump 6 is provided. The water pump 6 is used to generate power for the water flow in the pipe 5, thereby forming a circulating water circuit inside the ice-making device.

[0052] The filter mechanism 3 is arranged between the ice storage box 2 and the water tank 4. The filter mechanism 3 includes a receiving chamber 31 located on the water tank 4 and a filter hopper 32 arranged at the bottom of the receiving chamber 31. The receiving chamber 31 is used to receive the ice water flowing out of the leak hole 21 of the ice storage box 2. The "ice water" here can be understood as a substance mixed with liquid water and solid water (ice), which is a two-phase mixture.

[0053] The filter 32 is used to filter the ice water in the receiving chamber 31, guide the filtered liquid water into the water tank 4, and mix it into the water stored in the water tank 4. After multiple cycles, the temperature of the water stored in the original water tank 4 is rapidly reduced, thereby producing frozen water that can be directly drunk.

[0054] Compared with the prior art, the ice-making device provided in the present application improves the ice-making device of the mobile refrigerator. The ice-making device includes an ice-making mechanism 1, an ice storage box 2, a filtering mechanism 3 and a water tank 4 arranged in sequence. The water tank 4 is connected to the ice-making mechanism 1 through a pipe 5, thereby forming a circulating water circuit to achieve repeated ice making.

[0055] The filter mechanism 3 is arranged between the ice making mechanism 1 and the water tank 4, and includes a receiving chamber 31 and a filter hopper 32. The receiving chamber 31 is located on the water tank 4 and can receive ice water flowing out of the ice storage box 2. The filter hopper 32 is arranged at the bottom of the receiving chamber 31 and extends into the water tank 4, filtering out liquid water in the ice water and guiding it into the water tank 4. The water temperature in the original water tank 4 is rapidly reduced, and after multiple cycles, frozen water is formed for direct drinking, so that ice making and direct drinking frozen water can be produced at the same time.

[0056] In the above process, based on the circulating water circuit structure of the ice-making device of the present application, as the water temperature in the water tank 4 gradually decreases, the temperature of the water directed to the water-carrying pocket 12 for ice making becomes lower, which is beneficial to accelerate ice making and thus improve ice making efficiency.

[0057] In addition, the ice-making device of the present application can also control the ice maker 11. In addition to making ice, the ice maker 11 can also be used to prepare water for ice making in the water carrying bag 12. After refrigeration, the driver 13 drives the water carrying bag 12 to flip and output it directly to the water tank 4, so that the water stored in the water tank 4 becomes chilled water, thereby realizing the function of independently producing chilled water.

[0058] It can be seen that in the mobile refrigerator provided in the embodiment of the present application, the ice-making device can not only produce ice cubes but also produce chilled water during the ice-making process, thereby effectively improving the overall performance of the mobile refrigerator and meeting the user's usage needs.

[0059] In a conventional mobile refrigerator with an ice-making function, the ice-making part and the ice-storing part of the ice-making module are generally connected by an inclined channel, so that the formed ice cubes slide from the inclined channel to the ice-storing part. Such an internal layout occupies a large space, resulting in the inability to reduce the size of the entire machine.

[0060] Here, in the embodiments of the present application, please refer to Figure 1 , Figure 2 and Figure 3 The ice-making mechanism 1, the ice storage box 2 and the water tank 4 in the ice-making device are arranged in sequence from top to bottom and vertically aligned, and the bottom of the water tank 4 is connected to the ice-making mechanism 1 through a pipe 5. The vertical alignment of the components inside the ice-making device is conducive to reducing the occupied width of the ice-making device, thereby improving the compactness between the components and maximizing the saving of the internal space of the mobile refrigerator.

[0061] Among them, the driver 13 can preferably be a flip motor that can drive the object to rotate. The driver 13 is arranged on one side of the water carrying bag 12. The output end of the driver 13 is connected to one end of the water carrying bag 12, and drives the water carrying bag 12 to flip in a horizontal state.

[0062] Thus, the driver 13 is used to drive the water carrying bag 12 to flip so that the opening of the water carrying bag 12 after flipping faces downward, thereby directly pouring the produced ice cubes onto the ice storage box 2. Compared with the internal layout of the traditional ice making module, the inclined channel between the ice making part and the ice storage part is eliminated, the space occupied by the ice making device inside the mobile refrigerator is saved to the maximum extent, and it is helpful to reduce the overall volume of the mobile refrigerator.

[0063] For the structure of the water storage box, in one embodiment of the present application, please refer to Figure 3 The bottom of the ice storage box 2 is a filter grid formed by a plurality of leak holes 21 . When the ice storage box 2 is installed on the mobile refrigerator, the ice storage box 2 is located above the water tank 4 so that the filter grid is located within the receiving range of the receiving chamber 31 .

[0064] In this way, the ice cubes and ice water received by the ice storage box 2 are filtered once by the filter grid at the bottom of the ice storage box 2, so that the ice cubes remain on the ice storage box 2 for use. The ice water is filtered out by the filter grid and flows into the receiving chamber 31 for secondary filtration, so that the liquid water can subsequently flow into the water tank 4 to form directly drinkable frozen water.

[0065] For the structure of the filter mechanism 3, in one embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 5The filtering mechanism 3 also includes a cover body 33 located at the bottom of the receiving chamber 31. The cover body 33 covers the opening of the water tank 4, which is beneficial to prevent the water stored in the water tank 4 from overflowing when the mobile refrigerator is in an accidental situation such as tilting or falling, thereby achieving an anti-dumping effect and effectively solving the internal leakage problem of the mobile refrigerator.

[0066] In this embodiment, if Figure 4 and Figure 5 As described above, one side of the water tank 4 is provided with an operation groove 41 for manual operation to pull the water tank 4 out of the mobile refrigerator, so that the inner wall of the water tank 4 has a boss 42 corresponding to the position of the operation groove 41. In coordination, a shelf bar (not shown) opposite to the boss 42 is also provided on the inner wall of the water tank 4, so that the cover body 33 can be placed on the boss 42 and the shelf bar, thereby covering the opening of the water tank 4.

[0067] In other embodiments (not shown), an inner convex ring (not shown) is provided on the inner wall of the entire water tank 4 so that the cover 33 can be placed on the inner convex ring and can also cover the opening of the water tank 4.

[0068] In this embodiment, if Figure 5 As described above, the cover 33 divides the water tank 4 into a receiving chamber 31 and a water storage chamber 43, which are arranged vertically. The receiving chamber 31 is located above the water storage chamber 43. The filter hopper 32 is arranged on the cover 33 and extends into the water storage chamber 43. The ice water collected in the receiving chamber 31 is filtered by the filter hopper 32, and the liquid water obtained flows out of the filter hopper 32 and is guided to the water storage chamber 43 of the water tank 4, where it is mixed with the original stored water to reduce the temperature and produce directly drinkable frozen water.

[0069] In the examples of this application, please refer to Figure 4 The cover body 33 is also provided with a water inlet 331 , and the filter hopper 32 is detachably arranged on the water inlet 331 of the cover body 33 .

[0070] In this way, when adding water to the water tank 4, the cover body 33 does not need to be removed, and the water inlet 331 on the cover body 33 can be used for water replenishment. The filter hopper 32 is a detachable plugging member on the water inlet 331, and can be removed from the cover body 33 during the water adding operation. When the water replenishment is completed, it is reinstalled on the cover body 33 to block the water inlet 331 to prevent tipping.

[0071] For the structure of the filter hopper 32, in one embodiment of the present application, please refer to Figure 4 , Figure 5 and Figure 6The filter hopper 32 includes an upper port 321 and a lower port 322, and the filter hopper 32 is preferably a tapered cylinder whose inner diameter gradually decreases from the upper port 321 to the lower port 322. In this embodiment, the filter hopper 32 is preferably a conical structure, so that the interior of the filter hopper 32 is smooth and avoids the formation of a corner, so that the ice water can flow smoothly to the lower port 322, thereby improving the flow smoothness.

[0072] In this embodiment, the upper port 321 of the filter bucket 32 ​​is preferably matched with the water inlet 331 on the cover body 33, and an outer convex ring 323 is provided on the upper port 321 of the filter bucket 32, and the outer convex ring 323 is arranged around the outer circumference of the upper port 321. The outer convex ring 323 is used to be suspended on the water inlet 331 of the cover body 33, so as to facilitate the disassembly and assembly of the filter bucket 32.

[0073] The outer convex ring 323 on the filter bucket 32 ​​is preferably a flange bent outward on the upper port 321 of the filter bucket 32, which is easy to process and shape, thereby reducing the processing cost.

[0074] The lower port 322 of the filter bucket 32 ​​is preferably a flat port, which can only allow liquid water to pass through, which is beneficial for filtering the solid in the ice water, thereby obtaining completely liquid frozen water.

[0075] In addition, the flat opening of the lower port 322 of the filter bucket 32 ​​plays a role in preventing water from backflowing from the lower port 322 of the filter bucket 32 ​​to the recovery chamber 31, effectively solving the problem of internal water seepage in the mobile refrigerator under unexpected conditions (such as tipping over).

[0076] In one embodiment of the present application, please refer to Figure 5 and Figure 7 The ice making device also includes a sterilizing device 7, which is arranged on the pipeline 5. The sterilizing device 7 can preferably be composed of an LED UV sterilizing lamp module, and sterilizes the water flowing through the pipeline 5 by ultraviolet rays.

[0077] In this way, the water in the mobile refrigerator can be kept clean, and the ice cubes or frozen water that are conveniently made can be drunk directly, ensuring healthy drinking.

[0078] For the overall structure of the mobile refrigerator, in the embodiments of the present application, please refer to Figure 7 The ice-making device also includes a shell 8, which has a side opening 81. The side opening 81 corresponds to the positions of the ice storage box 2 and the water tank 4. The ice storage box 2 and the water tank 4 can be pulled out or pushed into the shell 8 through the side opening 81.

[0079] On the one hand, the ice storage box 2 can be pulled out or pushed into the housing 8 like a drawer. On the other hand, before the water tank 4 is pulled out, the water tank 4 can be lifted through the side opening 81 to separate the bottom of the water tank 4 from the pipe 5, and then the water tank 4 can be pulled out from the side opening 81. This is conducive to the separation operation of the water tank 4 and the pipe 5.

[0080] As described above, since the water tank 4 is detachably arranged on the mobile refrigerator, a protective structure that can prevent water leakage after separation needs to be arranged between the bottom of the water tank 4 and the pipe 5.

[0081] Here, in the embodiments of the present application, please refer to Figure 5 , Figure 8 and Fig. 9 A one-way valve 9 is provided at the connection portion between the bottom of the water tank 4 and the pipeline 5. The one-way valve 9 includes a bracket 91, an elastic member 92, a piston 93 and a ejector pin 94. A water outlet 44 is provided at the bottom of the water tank 4, and the bracket 91 is arranged on the water outlet 44 of the water tank 4.

[0082] The elastic member 92 may preferably be a spring, which is disposed on the bracket 91 and connected to the piston 93 . The elastic member 92 is used to push the piston 93 toward the water outlet 44 so that the piston 93 keeps blocking the water outlet 44 .

[0083] The ejector pin 94 is arranged on the connection end of the pipe 5, specifically, on the connection head of the pipe 5. When the pipe 5 is connected to the bottom water outlet 44 of the water tank 4, the ejector pin 94 can push the piston 93 up from the water outlet 44 to open the water outlet 44.

[0084] Therefore, a one-way valve 9 is provided at the connection part between the bottom of the water tank 4 and the pipe 5, so that the water outlet 44 of the water tank 4 can be automatically blocked when the water tank 4 is separated from the pipe 5, thereby preventing water leakage of the water tank 4. After the water tank 4 is installed back into the mobile refrigerator, the pipe 5 is connected to the water outlet 44 at the bottom of the water tank 4, and the piston 93 is pushed by the ejector pin 94 to automatically open the water outlet 44, thereby ensuring that the water circulation system in the ice-making device is unblocked and the ice-making device works normally.

[0085] Regarding the overall structure of the mobile refrigerator, the mobile refrigerator can be used as a vehicle refrigerator, installed in a vehicle compartment and connected to the vehicle power supply. In the embodiment of the present application, the mobile refrigerator can also be used as an independent device and separated from the vehicle. A rechargeable battery (not shown) is also provided on the power supply part of the mobile refrigerator, and the rechargeable battery is used to power the mobile refrigerator. The rechargeable battery has a charging interface so as to connect to a power supply for charging.

[0086] As an example, the rechargeable battery can preferably be a 12-24V rechargeable battery, and the charging interface on the rechargeable battery can be connected to the vehicle-mounted charger. In addition, the charging interface on the rechargeable battery can also be preferably a USB interface, which can be charged by connecting a power source outside the vehicle through a cable, effectively meeting the use requirements.

[0087] Preferably, the rechargeable battery is detachably arranged on the mobile refrigerator, so that the rechargeable battery can be removed separately for charging, or directly replaced with a new rechargeable battery for rapid battery life use.

[0088] In addition, in one embodiment of the present application (not shown in the figure), a handle and rollers are provided on the mobile refrigerator, and the rollers are arranged at the bottom of the mobile refrigerator to facilitate the relocation of the mobile refrigerator.

[0089] In this embodiment, the handle may include a pulling handle and a lifting handle, and the lifting handle is convenient for the user to directly lift the mobile refrigerator to a new location.
