Description

Technical Field

[0002] An ice maker is a device that produces ice. In the scorching summer heat, people use the ice to make cold dishes and foods, which is an effective way to cool down. Ice makers are increasingly used in our daily lives and work. Ice makers are generally divided into immersion ice makers, flow ice makers, and extrusion ice makers. Extrusion ice makers offer excellent ice dispensing quality and continuous ice production, making them increasingly popular with consumers in recent years. The existing squeeze-type ice maker's circulating water circuit typically includes upper and lower water tanks, a water supply pump, an ice evaporator, and circulating pipes. Over time, scale and dirt may accumulate in various parts of the circulating water circuit due to sedimentation. To address this issue, existing ice makers also have technical solutions with self-cleaning functions. However, these automatic cleaning methods typically use a full-liquid cleaning method, which results in insufficient flushing force and makes it difficult to completely clean scale and dirt in the circulating water circuit. In particular, scale and dirt located within the ice evaporator and circulating pipes are difficult to flush out, resulting in poor overall self-cleaning effectiveness, affecting the use of the ice maker and the quality of ice produced. Therefore, it is necessary to improve and optimize the structure of the ice maker to enhance the effectiveness of the self-cleaning function in its application. Utility Model Content

They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention. Figure 1-7The ice maker shown in the figure includes an upper water tank body 1, an ice-making evaporator assembly 2, a lower water tank 3, a water supply pump 4, a pressure water pump 5 and a controller 6. The upper water tank body 1, the ice-making evaporator assembly 2, the lower water tank 3, the water supply pump 4 and the pressure water pump 5 are connected by water pipes to form a circulating water circuit; the upper water tank body 1 is provided with an upper water tank cavity 101 and an ice storage tank 102, the upper water tank cavity 101 is provided with an upper water tank water inlet 7 and an upper water tank water outlet 8, and the ice storage tank 102 is provided with an evaporator installation port 9; the ice-making evaporator assembly 2 includes an ice-making cylinder 201 and an evaporator 202, the evaporator 202 is sleeved on the outside of the ice-making cylinder 201, and the lower part of the ice-making cylinder 201 is provided with an ice-making water inlet 10, and the ice-making water inlet 10 is connected to the upper water tank water outlet 8; the ice-making cylinder 2 01 has an ice outlet 11 at the top, and the top of the ice-making cylinder 201 is located in the evaporator mounting port 9; the pressure water pump 5 is arranged between the upper water tank body 1 and the ice-making evaporator assembly 2, and its water inlet end is connected to the upper water tank water outlet 8, and the water supply end is connected to the ice-making water inlet 10, for supplying water to the ice-making cylinder 201; the lower water tank 3 is provided with a lower water tank outlet 12, and the water supply pump 4 is arranged between the lower water tank 3 and the upper water tank body 1, and its water inlet end is connected to the lower water tank outlet 12, and the water supply end is connected to the upper water tank inlet 7, for supplying water to the upper water tank cavity 101; the controller 6 is electrically connected to the water supply pump 4 and the pressure water pump 5, and is used to control the start or stop of water supply of the water supply pump 4 and the pressure water pump 5.

[0030] The main design principle of the ice maker of this embodiment is to add a pressure water pump 5 to the water circuit structure and combine the relevant components into a circulating water circuit, so that when the ice maker is self-cleaning, it can have a higher water flow pressure and flow rate, which is conducive to flushing and forcibly removing impurities such as scale in the water circuit, thereby improving the self-cleaning effect of the ice maker.

[0031] As shown in the accompanying drawings, in this embodiment, a float switch 13 for detecting the water level information of the upper water tank cavity 101 is provided on the upper water tank body 1. The water level of the upper water tank cavity 101 is controlled by the detection and control of the float switch 13 to meet the different control requirements of ice making water supply and cleaning water supply for the ice maker.

[0032] As shown in the accompanying drawings, in this embodiment, the lower water tank 3 is further provided with a lower water tank drain port 18, that is, the ice maker of this embodiment has a drainage function. The lower water tank drain port 18 is opened on the bottom surface of the lower water tank 3, and the opening and closing of the lower water tank drain port 18 can be controlled by an electric valve switch or a manual valve switch. When the ice maker is operating normally, the lower water tank drain port 18 is in a closed state. When drainage is required, the lower water tank drain port 18 is opened, and the water in the lower water tank 3 is discharged from the lower water tank 3 to the outside.

[0033] In a preferred embodiment, as shown in the accompanying drawings, in this embodiment, an upper water tank drain pipe 14 is further provided on the upper water tank body 1, and the upper water tank drain pipe 14 is connected to the lower water tank drain port 18. In this way, during the self-cleaning process of the ice maker, the lower water tank drain port 18 can be in a closed state to facilitate circulating flushing and cleaning. After the self-cleaning is completed, the final dirty cleaning water can be directly connected to the lower water tank drain port 18 through the upper water tank drain pipe 14 and discharged outward.

[0034] As shown in the accompanying drawings, in this embodiment, the water inlet 7 of the upper water tank is arranged in the vertical direction, and a water shield 15 is provided at the water inlet 7 of the upper water tank. Based on the structural arrangement of this embodiment, due to the obstruction of the water shield 15, the water flow will not splash out of the upper water tank cavity 101, and a larger flow rate can be used to supply water to the upper water tank cavity 101 to ensure the water supply speed, so as to perform high-flow-rate flushing and cleaning of the circulating water circuit of the ice maker and improve the self-cleaning efficiency.

[0035] As shown in the accompanying drawings, in this embodiment, the upper water tank water inlet 7 is arranged on one side of the upper water tank cavity 101, and the upper water tank water outlet 8 is arranged on the other side of the upper water tank cavity 101 relative to the upper water tank water inlet 7, so as to optimize the arrangement positions of the various components of the ice maker, and its layout is more reasonable, which is conducive to improving assembly efficiency and reducing the cost of improving and optimizing the structure of the ice maker.

[0036] In a preferred embodiment, the ice maker includes an upper cover 16, and a sterilizing device is provided on the upper cover 16 corresponding to the upper water tank cavity 101, as shown in the attached figure. Figure 7 As shown, the sterilization device of this embodiment is specifically an ultraviolet sterilization lamp 17 installed and fixed on the upper cover 16 of the ice maker. After installation, the ultraviolet sterilization lamp 17 is aligned with the direction of the upper water tank cavity 101. In this way, the controller 6 can control the start of the disinfection and sterilization function, sterilize the ice-making water in the upper water tank cavity 101, and then supply water for ice making, thereby ensuring the quality of the ice cubes produced.

[0037] In this embodiment, the water supply tank body 1 is an integrally formed part, which is convenient for production, processing and assembly, thereby improving assembly efficiency.

[0038] The above description is only for the preferred embodiment of the present invention, which should not be construed as limiting the claims. The present invention is not limited to the above embodiment, and its specific structure is allowed to be varied. In short, all variations made within the scope of protection of the independent claims of the present invention are also within the scope of protection of the present invention.
