[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] See Figures 1-14The layout of this spray-type ice maker includes a body 1, a water tank 2, and an ice-making evaporator 3. An ice-making chamber 4 is provided inside the body 1, and the ice-making evaporator 3 is located inside the ice-making chamber 4. An installation window 5 communicating with the ice-making chamber 4 is provided on the front side of the body 1. The water tank 2 is detachably installed on the installation window 5. When the water tank 2 is installed on the installation window 5, the ice-making chamber 4 is closed. When the water tank 2 is removed from the installation window 5, the ice-making chamber 4 is opened to expose the ice-making evaporator 3, so that the ice-making evaporator 3 can be maintained through the installation window 5.

[0032] The ice evaporator 3 is arranged horizontally on the ice chamber 4, and the water tank 2 is arranged horizontally on the installation window 5. The horizontal arrangement of the ice chamber 4 and the installation window 5 makes the overall structure more compact and suitable for installation in limited spaces. The installation window 5 is located in front of the ice chamber 4, and the water tank 2 is installed and removed from the front. This layout is ergonomic and convenient for users to operate.

[0033] The main body 1 is provided with a positioning mounting groove 6, and the water tank 2 is provided with a positioning strip 7 on the rear side. The positioning strip 7 is positioned and inserted into the mounting groove 6.

[0034] The bottom of the positioning strip 7 is provided with a support part 8, and the bottom wall of the mounting groove 6 is provided with a support surface 9. The positioning strip 7 is supported on the support surface 9 through the support part 8, so that the rear side of the water tank 2 is supported on the body 1.

[0035] The positioning strip 7 has several limiting ribs 10 distributed laterally on its front side, and the mounting groove 6 has a limiting part 11 on its front side, with the limiting ribs 10 pressing against the limiting part 11 forward; the positioning strip 7 has a limiting surface 12 on its rear side, and the mounting groove 6 has a limiting mating surface 13 on its rear side, with the limiting surface 12 pressing against the limiting mating surface 13 backward; this structure allows the water tank 2 to be positioned on the body 1 from front to back.

[0036] The front side of the body 1 is provided with an installation horizontal bar 14 that extends into the installation window 5. The positioning installation groove 6 is provided on the installation horizontal bar 14. The rear side of the water tank 2 is provided with a limit groove 15. The positioning bar 7 is located on the rear side of the limit groove 15. The installation horizontal bar 14 is positioned and inserted into the limit groove 15. This structure allows the water tank 2 to be positioned left and right on the body 1.

[0037] The lower part of the body 1 has a support part 16 protruding forward. The bottom of the water tank 2 is supported on the support part 16. Combined with the aforementioned positioning of the water tank 2 on the body 1 in all directions, the water tank 2 can only move upward after installation. Therefore, when disassembling the water tank 2, you only need to pull the water tank 2 upward. When installing the water tank 2, you only need to insert the water tank 2 downward into the body 1, which makes the disassembly and assembly of the water tank 2 very convenient.

[0038] The water tank 2 is equipped with a first top cover 31, which is fixed to the water tank 2 by a buckle. Water can be added to the water tank 2 by removing the first top cover 31.

[0039] The main body 1 includes an outer shell 17 and an inner liner 18 disposed inside the outer shell 17. The inner liner 18 is provided with an ice-making chamber 4 and an ice storage chamber 19 arranged vertically. An ice storage container 20 is pulled out from the ice storage chamber 19. The ice storage container 20 is an ice basket. The ice storage chamber 19 and the ice-making chamber 4 are arranged in a stepped manner to form an installation window 5 between the ice storage chamber 19 and the ice-making chamber 4. The installation window 5 is located above the ice storage chamber 19. This structure organically integrates the installation position of the water tank 2, the ice-making chamber 4 and the ice storage chamber 19 into one, compressing the overall volume of the machine.

[0040] The top of the outer casing 17 is covered with a second top cover 32, and a mounting strip 14 is provided on the front side of the second top cover 32.

[0041] An electrical chamber 21 is formed between the inner rear wall of the outer shell 17 and the outer rear wall of the inner liner 18. A drain valve 22 and a water pump 23 are installed within the electrical chamber 21. A water inlet chamber 24 is formed between the bottom wall of the inner liner 18 and the ice storage container 20. The inlet end of the drain valve 22 is connected to the water tank 2, and the outlet end of the drain valve 22 is connected to the water inlet chamber 24. The inlet end of the water pump 23 is connected to the water inlet chamber 24, and the outlet end of the water pump 23 is connected to the ice maker evaporator 3. The water tank 2, the ice storage container 20, and the water inlet chamber 24 are arranged vertically, and the ice maker evaporator 3, the drain valve 22, and the water pump 23 are also arranged vertically, making full use of the vertical and horizontal space and the front and rear space of the machine body 1. The drain valve 22 and water pump 23 are arranged horizontally, which can make full use of the left and right space of the body 1. At the same time, the two small electrical components are placed side by side, making the wiring in the electrical room 21 more compact and easier to maintain. When the drain valve 22 is opened, the water in the water tank 2 flows into the water inlet chamber 24 of the inner tank 18, and water is discharged from the bottom of the water tank 2. The drain valve 22 and the water inlet chamber 24 are located below the water tank 2. When the water pump 23 is working, it draws the water in the water inlet chamber 24 to the ice evaporator 3 for ice making. The ice blocks then fall downward into the ice storage container 20 for collection. The above ice making process is existing technology and will not be described in detail here.

[0042] An electrical compartment 21 is equipped with a partition 25, which divides the electrical compartment 21 into an upper chamber 26 and a lower chamber 27. The installation window 5, ice-making chamber 4, and upper chamber 26 are arranged sequentially front to back. The ice storage chamber 19 and lower chamber 27 are also arranged sequentially front to back. The ice-making chamber 4 and upper chamber 26 are arranged vertically above and below the lower chamber 27, respectively. A defrosting evaporator 28 is installed in the upper chamber 26. A compressor 29, condenser 30, drain valve 22, and water pump 23 are installed in the lower chamber 27. The compressor 29, condenser 30, and ice-making evaporator 3 are connected sequentially. The outlet pipe 37 of the ice-making evaporator 3, the defrosting evaporator 28, and the compressor 29 are connected sequentially. A water tank 2, ice-making evaporator 3, and defrosting evaporator 28 are arranged sequentially front to back. Water flows from the water tank 2 and is sprayed onto the ice-making evaporator 3 to make ice. The defrosting evaporator 28 is arranged close to the ice-making evaporator 3 to facilitate rapid heat absorption during defrosting. The ice container 20, drain valve 22, and compressor 29 are arranged sequentially front to back. The water inlet chamber 24, water pump 23, and compressor 29 are also arranged sequentially front to back. As the core heat source and vibration source, compressor 29 is placed in the corner of the rearmost lower chamber 27. The drain valve 22 and water pump 23 for water supply are arranged in front of compressor 29 to reduce the impact of the heat generated by compressor 29 on other components. The defrosting evaporator 28 and compressor 29 are arranged vertically, while compressor 29 and condenser 30 are arranged horizontally. The two main heat-generating components are placed side by side and can share the heat dissipation air duct, which is conducive to heat dissipation. In addition, the layout of the above components can make regular use of the vertical, horizontal, front, and back space of the body 1. The components are arranged closely in the three dimensions of length, width, and height, maximizing space utilization. Such a regular arrangement is conducive to modular assembly and standardized wiring on the production line.

[0043] The upper chamber 26 is also equipped with a dryer filter 33, a capillary tube 34, a solenoid valve 35, and a liquid receiver 36. The compressor 29, condenser 30, dryer filter 33, capillary tube 34, and the first inlet of the ice-making evaporator 3 are connected in sequence. The compressor 29, condenser 30, solenoid valve 35, liquid receiver 36, and the second inlet of the ice-making evaporator 3 are connected in sequence. The high-pressure gas generated by the compressor 29 enters the condenser 30, and then releases heat through the condenser 30 to form a low-temperature refrigerant. The low-temperature refrigerant passes through the dryer filter 33 and the capillary tube 34 in sequence and enters the ice-making evaporator 3. This path is a conventional refrigeration path. The high-pressure gas generated by compressor 29 enters condenser 30, and then releases heat through condenser 30 to form low-temperature refrigerant. The low-temperature refrigerant enters ice-making evaporator 3 through solenoid valve 35 and liquid receiver 36 in sequence. This path is the de-icing path, used for de-icing in ice-making evaporator 3. This path makes the temperature of the ice mold higher than that of the ice mold in the refrigeration path, causing the surface of the ice to melt slightly, so that the ice automatically falls off, which is beneficial for de-icing. In the conventional refrigeration path, the refrigerant returns to compressor 29 as a low-pressure liquid, while in the de-icing path, the refrigerant returns to compressor 29 as a high-pressure gas.

[0044] A water collection tray 38 is provided below the defrosting evaporator 28. The water collection tray 38 is integrally set on the partition plate 25. When the refrigerant passes through the defrosting evaporator 28, it absorbs heat and then returns to the compressor 29 to form a cycle, which can melt the ice layer on the surface of the ice-making evaporator 3. When the defrosting evaporator 28 is working, condensate is generated on its surface, and the condensate falls into the water collection tray 38 for collection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
