Description

Technical Field

[0001] This utility model belongs to the field of household appliances, specifically, it relates to ice makers, and more particularly to the evaporator tube structure of ice makers. Background Technology

[0002] The demand for ice has been long-standing. Originally, ice was obtained by filling molds with water and freezing it in the freezer compartment of a refrigerator. However, in more demanding settings like upscale restaurants and bars, a smaller, dedicated machine was desired to produce ice, leading to the development of the ice maker. The basic structure of this ice maker consists of an ice-making cup filled with water; an evaporator tube runs above the cup, with several protruding cooling ends that extend into the cup. These cooling ends gradually condense the water around them into ice. Before the ice on each cooling end solidifies, the cup is inverted, and the evaporator tube heats up, removing the ice from the cooling ends. This yields the same number of ice blocks as the cooling ends. Because temperature diffusion is isotropic, ice produced in this way has a uniform thickness in all directions; for example, when the cooling end has a hemispherical head, the resulting ice block also has a hemispherical head. Clearly, traditional ice-making methods cannot achieve this effect.

[0003] In this type of ice maker, after ice is formed using the cooling end as the ice nucleus, it remains submerged in water within the ice-making cup and is subject to buoyancy. This buoyancy may affect the evaporator tube, causing it to shift and thus impacting the entire ice-making process. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide an evaporator tube structure for an ice maker that can maintain stability.

[0005] Therefore, the technical solution adopted by this utility model is as follows: the evaporation tube structure of the ice maker includes an evaporation tube and an ice maker frame, the evaporation tube passing through the ice maker frame and forming a spiral inside it; the characteristic is that the inlet and outlet tubes of the evaporation tube passing through the ice maker frame are arranged adjacently; there is a large notch on the frame wall, and there are two semi-circular first small notches inside the large notch for placing the inlet and outlet tubes of the evaporation tube; it also includes a pressing block, the overall shape of the pressing block is consistent with the large notch, so that it can be assembled with the large notch and fixed by screws, the pressing block also has two semi-circular second small notches, which correspond one-to-one with the first small notches and are assembled into a complete circle; the circle formed by the first small notches and the second small notches is interference-fitted with the inlet and outlet tubes of the evaporation tube.

[0006] The evaporator tube, located within the frame, is fixedly connected to at least one connecting piece; the connecting piece is connected to the frame by screws.

[0007] This invention can fix the evaporator tube to the frame, preventing it from changing position due to buoyancy or other reasons; on the other hand, it can be installed and removed with a small number of screws, which is beneficial for arranging or replacing other parts in the frame. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of this embodiment.

[0009] Figure 2 This is a schematic diagram of a pressing block. Detailed Implementation

[0010] See the attached drawings. This embodiment includes an ice maker frame 1 and an evaporator tube 2. The evaporator tube is coiled inside the frame and connected to the outside via an inlet pipe 21 and an outlet pipe 22. The frame has a large notch and two smaller first notches. Since the large notch has been filled by the pressure block 3, it is not shown in the figure. After being filled by the pressure block 3, it fits with the frame and still presents a complete geometric shape.

[0011] Figure 2 The shown block and its position Figure 1 The state of the middle is reversed so that the two second small notches 31 at the bottom can be presented; it is not hard to imagine that the first small notch on the frame is the same shape as it and is pieced together to form a complete round hole, so that the inlet pipe 21 and the outlet pipe 22 are both locked in the two round holes.

[0012] The evaporator tube is fixedly welded with connecting piece 23 in Shanghai, and is also connected to the frame with screws.
