Description

Technical Field

[0001] This utility model relates to the field of ice maker technology, and in particular to an evaporator and an ice maker. Background Technology

[0002] Bullet-shaped ice makers on the market have evaporators equipped with an air inlet pipe 101 and an air return pipe 102, such as... Figure 6 As shown, the air inlet pipe 101 and the air return pipe 102 are arranged on the evaporator body 100, which makes the width of the evaporator relatively large. This will occupy a lot of space in the ice maker, making the size of the ice maker, especially the width, relatively large. As a result, the ice maker occupies a lot of space, has a small capacity, and has high mail order costs.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide an evaporator and ice maker that are simple in structure, small in size, occupy little space, have a reasonable layout, and are highly practical, so as to overcome the shortcomings of the prior art.

[0005] An evaporator designed for this purpose includes an evaporator body, an inlet pipe, and a return pipe, characterized in that: the inlet pipe and the return pipe are arranged vertically on the evaporator body, and the inlet pipe and the return pipe overlap at least partially in the top or bottom view projection direction, so as to reduce the width of the evaporator without changing the ice production capacity.

[0006] The intake pipe is located above the return pipe; there is a gap between the intake pipe and the return pipe, or the intake pipe and the return pipe are fitted together.

[0007] The intake pipe includes a first horizontal pipe section, and the return pipe includes an inclined pipe section. The inclined pipe section is set at an angle, with the upper end of the inclined pipe section at the same height as the first horizontal pipe section, and the non-upper part of the inclined pipe section located below the first horizontal pipe section.

[0008] The return pipe also includes a second horizontal pipe section, which is located at the lower end of the inclined pipe section. The first horizontal pipe section and the second horizontal pipe section are distributed vertically in sequence.

[0009] The evaporator body includes a U-shaped heat exchange tube. A first connecting pipe section and a second connecting pipe section are respectively provided on both sides of the heat exchange tube. The first connecting pipe section is connected to one end of the air inlet pipe, and the second connecting pipe section is connected to the upper end of the inclined pipe section.

[0010] The first connecting pipe section, the second connecting pipe section, and the first horizontal pipe section are located at the same height.

[0011] The first horizontal pipe section and the inclined pipe section are staggered.

[0012] The second horizontal pipe section is located directly below the first horizontal pipe section.

[0013] The first horizontal pipe section has a first vertical connecting pipe section that is bent downwards at the other end. The second horizontal pipe section has an inclined pipe section connected at one end and a second vertical connecting pipe section that is bent downwards at the other end.

[0014] An ice maker designed for this purpose includes a body, on which an ice-making chamber and the evaporator are provided, characterized in that: an air inlet pipe and an air return pipe are distributed vertically within the ice-making chamber, and a through hole is provided on the side of the ice-making chamber, through which the air inlet pipe and the air return pipe pass into the ice-making chamber.

[0015] The evaporator of this invention adopts an upper and lower layout for the air inlet pipe and the air return pipe, making full use of the vertical space. This allows the evaporator to be made smaller, especially its width, which can be made to within 180mm. This, in turn, reduces the width of the ice maker, allowing the packaging width of the ice maker to be within 200mm, increasing the container capacity and significantly reducing the mail order cost per unit.
