[0002] Ice cubes have become accessories in life, and miniaturized ice-making devices have gradually entered families. Especially in the hot summer, people can conveniently make ice while sitting at home and enjoy the cool taste that ice cubes bring to beverages and beer. An ice maker is an electrical device that can automatically make ice. At present, ice makers usually use a refrigeration system composed of a compressor, a condenser, an evaporator, and an expansion valve for refrigeration, providing low temperature for the ice-making mechanism to make ice.

[0003] For example, the patent number CN219868632U discloses an ice maker. An ice storage shell is arranged in its ice storage cavity. The ice storage shell is detachably installed in the ice storage cavity. A plurality of water filtering holes are formed in the bottom of the ice storage shell. There is a spacing between the bottom of the ice storage shell and the bottom of the ice storage cavity to facilitate water to drip through the water filtering holes to the bottom of the ice storage cavity. A drain port is arranged at the bottom of the ice storage cavity. The drain port is connected to the outside of the machine shell through a pipeline to facilitate the discharge of accumulated water. In the above structure, since the bottom of the ice storage shell is provided with water filtering holes, when the ice storage shell (ice storage box) is taken out of the machine, obvious water droplets flow out, resulting in water stains around the machine. Summary of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] The problem to be solved by the utility model is to provide an ice maker with an ice storage box for water supply to overcome the defect that the holes in the bottom of the existing ice storage box are likely to cause water stains around the machine.

[0006] (II) Technical Solutions

[0007] To solve the above technical problem, the utility model provides an ice maker with an ice storage box for water supply, which includes a housing. A fixed water tank and a detachably openable ice storage box are arranged at the front end of the housing. After installation, the ice storage box is located above the water tank. An accommodating cavity for storing water or ice is arranged in the ice storage box. A water passing port is arranged at the bottom position of the accommodating cavity. The accommodating cavity can be communicated with the water tank through the water passing port. When the ice storage box filled with water is installed on the housing, the water passing port is communicated with the inner cavity of the water tank, and the water in the accommodating cavity is discharged into the water tank through the water passing port.

[0008] This solution adopts the concept of integrating the ice box and the water box, and uses a single movable part (ice box) to store ice and add water. The water tank can be set inside the shell. Compared with the traditional structure of ice box for ice storage and water box for water addition, the number of external movable parts is reduced, the structure is simpler, and the operation is easier. In addition, the bottom of the ice box does not need to be hollowed out. When the ice box is pulled out, the control switch is automatically turned off, and no water drops will flow out, ensuring that the surrounding area of ​​the machine is clean and tidy.

[0009] In some embodiments, the water outlet is arranged at the bottom side end position of the ice storage box, and a control switch for opening or closing the water outlet is installed at the water outlet; when the ice storage box is installed on the shell, the control switch opens the water outlet; when the ice storage box is removed from the shell, the control switch closes the water outlet.

[0010] This solution adopts a control switch to control the automatic opening and closing of the water outlet, which has a high degree of automation and is more convenient to use.

[0011] In some embodiments, the control switch is a one-way valve, which includes a valve stem slidably mounted in the water outlet and a sealing valve plate mounted at the end of the valve stem for opening and closing the water outlet, and a driving wall corresponding to the valve stem is provided on the housing or the water tank; when the ice storage box is mounted on the housing, the driving wall pushes the valve stem to make the sealing valve plate detach from the water outlet, thereby opening the water outlet. A spring is installed between the valve stem and the water tank, and the spring is sleeved on the valve stem, and the spring always makes the sealing valve plate tend to move toward the water outlet; when the ice storage box is removed from the housing, the spring makes the sealing valve plate fit the water outlet, thereby closing the water outlet.

[0012] In this solution, the control switch adopts a one-way valve, which can not only ensure the realization of the function but also has a simpler structure.

[0013] In some embodiments, the ice storage box is withdrawable and mounted at the front end of the shell; and / or a water level mark is provided on the inner wall of the accommodating cavity.

[0014] In this solution, the ice storage box is installed by pulling out, which is more convenient to operate; a water level scale is set to facilitate observation of the water level when adding water to prevent excessive water addition.

[0015] In some embodiments, a limiting protrusion is symmetrically provided on the bottom wall of the inner end of the ice storage box, and the limiting protrusion is used to limit the direct withdrawal of the ice storage box; the inner end of the ice storage box is provided with an inclined portion, and the limiting protrusion is located at the end of the inclined portion; and the top of the inner end of the ice storage box is provided with a recessed portion corresponding to the inclined portion.

[0016] In this solution, when the ice storage box is pulled out, the limiting bump can abut against the housing to block the ice storage box, thereby restricting the complete extraction of the ice storage box, avoiding the risk of the ice storage box falling when it is completely pulled out, and ensuring the safety of use. The inclined part and the concave part are arranged in cooperation, so that the height dimension of the inner end of the ice storage box is reduced. When the ice storage box is horizontally pulled out to the end, the ice storage box can be tilted so that the limiting bump can cross the extraction opening of the housing, so that the ice storage box can be completely taken out, and it is also convenient to put the ice storage box into the housing.

[0017] In some embodiments, a handle is installed at the outer end of the ice storage box, and damping bumps are symmetrically arranged at one end of the bottom of the ice storage box close to the handle.

[0018] In this solution, the damping bumps can block the movement of the ice storage box, have a certain damping effect, have a better feel in use, and also prevent the ice storage box from being accidentally pulled out.

[0019] In some embodiments, the housing includes a heat preservation outer shell for forming the water tank, and the ice storage box is horizontally slidably installed on the heat preservation outer shell; a water pump is installed at the bottom of the heat preservation outer shell, and the water inlet end of the water pump communicates with the water tank.

[0044] The following describes the technical solutions provided by each embodiment of this application in conjunction with the accompanying drawings.

[0045] Refer to Figures 1 to 13 , this utility model provides an ice storage box water supply type ice maker, which includes a housing 1. A fixed water tank 11 and a detachable and openable ice storage box 5 are provided at the front end of the housing 1. After installation, the ice storage box 5 is located above the water tank 11. An accommodation cavity 501 for storing water or ice is provided in the ice storage box 5, and the water tank 11 is used for caching water. A water passing port 502 is provided at the bottom position of the accommodation cavity 501. The accommodation cavity 501 can be communicated with the water tank 11 through the water passing port 502. When the ice storage box 5 filled with water is installed on the housing 1, the water passing port 502 is communicated with the inner cavity of the water tank 11, and the water in the accommodation cavity 501 is discharged into the water tank 11 through the water passing port 502.

[0046] Refer to Figures 2 to 4 , the water passing port 502 is provided at the inner side end position of the bottom of the ice storage box 5, and a control switch 51 for opening or closing the water passing port 502 is installed at the water passing port 502. When the ice storage box 5 is installed on the housing 1, the control switch 51 opens the water passing port 502. When the ice storage box 5 is detached from the housing 1, the control switch 51 closes the water passing port 502.

[0047] This structure adopts the concept of integrating an ice box and a water box. Before the ice maker works, the user can add water to the ice storage box. After installing the ice storage box on the housing, the control switch 51 automatically opens, and the water in the ice storage box 5 automatically flows into the water tank 11. By using a single movable part (the ice storage box) for ice storage and water addition, the water tank can be set inside the housing. Compared with the traditional structure of using an ice box for ice storage and a water box for water addition, the number of external movable parts is reduced, the structure is simpler, and the operation is more convenient. Moreover, there is no need to hollow out the bottom of the ice storage box 5. When the ice storage box is pulled out, the control switch 51 automatically closes, and no water droplets will flow out, ensuring that the surrounding of the machine is clean and tidy.

[0048] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 shown, the control switch 51 is a one-way valve, which has a simple structure and good use effect. The one-way valve includes a valve stem 511 slidably installed in the water passing port 502 and a sealing valve plate 512 installed at the end of the valve stem 511 for opening and closing the water passing port 502. A driving wall 103 corresponding to the valve stem 511 is provided on the housing 1 or the water tank 11, and the driving wall 103 is used to drive the valve stem 511 to slide. In this embodiment, since the water tank 11 is fixedly arranged inside the housing 1 and the ice storage box 5 is slidably installed on the water tank 11, the driving wall 103 is arranged on the inner wall of the water tank 11. When the ice storage box 5 is installed on the housing 1, the driving wall 103 pushes the valve stem 511 to make the sealing valve plate 512 disengage from the water passing port 502, thereby opening the water passing port 502.

[0049] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 shown, a spring 513 is installed between the valve stem 511 and the water tank 11. The spring 513 is sleeved on the valve stem 511, and the spring 513 always makes the sealing valve plate 512 tend to move towards the water passing port 502. When the ice storage box 5 is removed from the housing 1, the driving wall 103 disengages from the valve stem 511. Under the spring force of the spring 513, the spring 513 makes the sealing valve plate 512 fit the water passing port 502, thereby closing the water passing port 502. With this structure, when the ice storage box is pulled out, the spring 513 makes the water passing port 502 automatically close, and no water droplets will flow out of the ice storage box, ensuring that the surrounding of the machine is clean and tidy.

[0050] In some embodiments, such as Figure 3 shown, the ice storage box 5 can be slidably installed at the front end of the housing 1; and / or, a water level scale line is provided on the inner wall of the accommodation cavity 501. With this structure, the ice storage box 5 is installed in a sliding manner, which is more convenient for operation; by setting the water level scale line, it is convenient to observe the water level during water addition to prevent overwatering.

[0051] In some embodiments, such as Figure 4 and Figure 9As shown, on the bottom wall of the inner end of the ice storage box 5, limiting bumps 503 are symmetrically arranged. The limiting bumps 503 are used to prevent the direct extraction of the ice storage box 5. An inclined portion 504 is arranged at the inner end of the ice storage box 5. The limiting bumps 503 are located at the end of the inclined portion 504. A recessed portion 505 corresponding to the inclined portion 504 is arranged at the top of the inner end of the ice storage box 5. In this structure, with the arrangement of the limiting bumps 503, when the ice storage box 5 is extracted, the limiting bumps 503 can abut against the housing to block the ice storage box 5, thereby restricting the complete extraction of the ice storage box 5, avoiding the risk of the ice storage box 5 falling when it is completely extracted, and ensuring the safety of use. The cooperation of the inclined portion 504 and the recessed portion 505 is set to reduce the dimension of the ice storage box 5 in the height direction at the inner end. When the ice storage box 5 is horizontally extracted to the end, the ice storage box 5 can be tilted to facilitate the limiting bumps 503 to cross the extraction opening of the housing, so that the ice storage box 5 can be completely taken out, and it is also convenient to put the ice storage box 5 into the housing.

[0052] In some embodiments, as Figure 4 and Figure 9 shown, a handle 52 is installed at the outer end of the ice storage box 5. At one end of the bottom of the ice storage box 5 close to the handle 52, damping bumps 506 are symmetrically arranged. In this structure, with the arrangement of the damping bumps 506, when the ice storage box 5 is pulled, the damping bumps 506 can block the movement of the ice storage box 5, having a certain damping effect, with a better feel in use, and also preventing the ice storage box 5 from being accidentally pulled out.

[0053] In some embodiments, as Figure 6 、 Figure 8 and Figure 9 shown, the housing 1 includes a heat-insulating outer shell for forming the water tank 11. The ice storage box 5 is horizontally slidably installed on the heat-insulating outer shell. A water pump 10 is installed at the bottom of the heat-insulating outer shell. The water inlet end of the water pump 10 communicates with the water tank 11, and the water outlet end of the water pump 10 is connected to the inner water box 3.

[0054] In some embodiments, as Figure 2 as well as Figures 10 to 12As shown in the figure, a freezing chamber 101 is formed above an ice storage box 5 in a housing 1. An evaporator 2 is disposed in the freezing chamber 101 and extends in the front-rear direction. A plurality of ice-making die heads 21 extending downward are evenly distributed on the evaporator 2. An inner water box 3 capable of accommodating the ice-making die heads 21 is rotatably installed in the freezing chamber 101. An outer water box 4 capable of rotating synchronously with the inner water box 3 is sleeved outside the inner water box 3. A drainage channel 401 is formed between the inner water box 3 and the outer water box 4. One end of the outer water box 4 is provided with a drainage port 402, and the drainage channel 401 communicates with a water tank 11 through the drainage port 402. With this structure, by means of the arrangement of the inner water box and the outer water box, a drainage channel is formed between the inner and outer water boxes. Through the drainage channel and the drainage port provided on one side of the outer water box, it is ensured that when pouring water to drop the ice after ice-making is completed, the remaining water in the inner water box can only enter the water tank through the drainage channel and the drainage port, and will not enter the ice storage box. Among them, in this embodiment, an ice-making machine for bullet ice is taken as an example for illustration, and the structures of the above-mentioned ice storage box and water tank can also be used in other ice-making machines.

[0055] In some embodiments, as Figure 2 、 Figure 10 and Figure 13 shown, an ice-making outer shell 12 is disposed outside the freezing chamber 101 of the housing 1. The inner water box 3 and the outer water box 4 are installed in the ice-making outer shell 12. A motor for driving the inner water box 3 and the outer water box 4 to rotate together is installed on the ice-making outer shell 12. One end of the ice-making outer shell 12 is provided with a water discharge channel 121 corresponding to the drainage port 402, and the water discharge channel 121 communicates with the water tank 11. The housing 1 further includes an outer cover shell 14. A bracket 15 is installed at the rear side inside the outer cover shell 14. A compressor 7 is installed between the water tank 11 and the bracket 15. A condenser 8 and a cooling fan 9 for dissipating heat from the condenser 8 are installed on the bracket 15.

[0056] During ice-making, a water pump 10 adds water in the water tank 11 to the inner water box 3. Then the compressor 7 is started, and the evaporator 2 refrigerates. The ice-making die heads 21 of the evaporator 2 are immersed in the clear water part of the inner water box 3 to freeze. After ice-making is completed, the inner water box 3 and the outer water box 4 rotate synchronously to pour water. The remaining water in the inner water box 3 is poured into the drainage channel 401, and then discharged into the water tank 11 through the drainage port 402 and the water discharge channel 121. After drainage is completed, the compressor 7 switches the pipeline through an electromagnetic valve to heat the evaporator 2, and the ice cubes on the ice-making die heads 21 fall into the ice storage box 5. Finally, the inner water box 3 and the outer water box 4 rotate synchronously to reset.

[0057] For the same and similar parts among the various embodiments in this specification, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0058] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
