[0002] An ice maker is a refrigeration machine that uses a refrigeration system to cool water through an evaporator to produce ice. It employs a refrigeration system with water as the carrier, and produces ice by passing the water through a device when powered on. Depending on the evaporator's principle and production method, the resulting ice blocks can have different shapes, including cube ice, extruded ice, and crescent-shaped ice.

[0027] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.
[0028] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.
[0029] Please refer to Figures 1-3 As shown, this application provides an ice maker, including a housing 1. The housing 1 is equipped with a compressor 3, a condenser 5, and an evaporator. The condenser 5 is connected to both the compressor 3 and the evaporator. The evaporator is connected to the compressor 3. The evaporator includes a first receiving box 7, in which an ice tray 13 is provided. A heating wire 9 is provided on the outside of the first receiving box 7. The heating wire 9 is arranged around the first receiving box 7, increasing the contact area between the heating wire 9 and the first receiving box 7. This ensures that each side wall of the first receiving box 7 is surrounded by the heating wire 9. During de-icing, the heat from the heating wire 9 can be transferred from each side wall to the ice tray 13, thereby significantly improving the de-icing speed.
[0030] Furthermore, the heating wires 9 are spirally or meanderingly arranged around the outside of the first receiving box 7 from top to bottom or bottom to top. This arrangement ensures that the outside of the first receiving box 7 is equipped with heating wires 9 from bottom to top, so that each side wall has high heat during de-icing. This not only increases the de-icing speed but also prevents uneven heating of the ice tray 13 from affecting the quality of de-icing.
[0031] like Figures 4-6 As shown, the evaporator also includes a second receiving box 8, which is located outside the first receiving box 7. The second receiving box 8 has a through hole for a pipe to pass through. The housing 1 has a platform 2, on which a first connecting part and an ice-receiving port are provided. The second receiving box 8 is connected to the first connecting part, and the first receiving box 7 is located below the ice-receiving port. Specifically, the opening of the first receiving box 7 has an outwardly flared protrusion that overlaps the ice-receiving port. The first connecting part is located on the lower surface of the platform 2 and is a slot. Since the heating wire 9 and the first pipe 12 are located outside the first receiving box 7, the second receiving box 8 isolates the heating wire 9 and the first pipe 12 from the external environment inside the housing 1, preventing damage to the heating wire 9 and the first pipe 12.
[0032] In one embodiment of this disclosure, a dryer filter 6 is also included, which is connected to both the evaporator and the condenser 5. The compressor 3 includes a pump assembly and a receiver for holding the refrigerant. After the compressor 3 starts operating, the refrigerant flows from the receiver into the condenser 5 and the dryer filter 6 sequentially. The refrigerant is condensed in the condenser 5 and then dried in the dryer filter 6. The dried refrigerant then enters the evaporator and cools the water in the ice tray 13. The water in the ice tray 13 is gradually cooled over time and with the progress of the refrigeration cycle, eventually freezing into ice. Finally, the refrigerant flowing through the evaporator returns to the compressor 3 via a pipeline. After ice making is complete, the refrigerant stops working in the evaporator, and simultaneously, the heating wire 9 starts working to heat the evaporator, melting the ice at the point where it contacts the corresponding ice tray 13, thus performing the de-icing process.
[0033] It should be noted that the ice tray 13 in this application can be a square ice tray, a spherical ice tray, a cylindrical ice tray, a crescent-shaped ice tray, or an irregularly shaped ice tray. Furthermore, the ice maker in this application does not require adding water to the ice tray 13; instead, stainless steel ice cubes adapted to the shape of the ice tray 13 are placed inside to cool the ice cubes. The stainless steel ice cubes can replace the function of traditional ice cubes, providing a longer cooling duration, and the melting of the stainless steel ice cubes will not affect the taste of the beverage. Moreover, the stainless steel ice cubes can be reused.
[0034] The compressor 3 has a first outlet, and the condenser 5 has a first inlet. The first outlet is connected to the first inlet via a first pipe 12. The first pipe 12 is at least partially spiral or meandering around the outside of the first receiving box 7. When the refrigerant enters the first pipe 12, it begins to cool the water in the ice tray 13. Specifically, the first pipe 12 and the heating wire 9 are alternately arranged around the outside of the first receiving box 7. The first pipe 12 spirals or meanders around the outside of the first receiving box 7 from top to bottom or bottom to top, increasing the contact area between the refrigerant and the first receiving box 7 and improving ice-making efficiency. During ice making, the refrigerant can be felt on all side walls, resulting in a more uniform cooling trend in each ice tray 13, thereby accelerating the ice-making speed.
[0035] like Figure 1 As shown, in one embodiment of this disclosure, the housing 1 is provided with a bottom plate 10 and a side plate 11. The compressor 3 is disposed on the bottom plate 10, and the condenser 5 is disposed on the side plate 11. A control button is also provided on the tabletop 2, which is used to control the operation of the compressor 3 and the heating element 9. A battery pack 15 for powering the ice maker is also connected to the side plate 11.
[0036] Please continue reading. Figure 1 As shown, in one embodiment of this disclosure, an evaporator and a condenser 5 are connected in series with a solenoid valve 14. The solenoid valve 14 is connected in series with the evaporator and the condenser 5 to achieve the switching between the evaporator and the condenser 5. During ice making, refrigerant enters the evaporator and cools the water in the ice tray 13 until the water in the ice tray 13 freezes into ice. During de-icing, the solenoid valve 14 converts the original evaporator into a condenser 5, heating the ice tray 13 to facilitate the de-icing of the ice.
[0037] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
