Description

Technical Field

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

[0002] The bullet ice evaporator is the core component of an ice maker. It is generally constructed by welding 304 stainless steel pipes and 304 stainless steel ice-making heads. The 304 stainless steel pipe serves as the main pipe, and the 304 stainless steel ice-making heads are welded onto and connected to the main pipe. The main pipe carries refrigerant and delivers it to the 304 stainless steel ice-making heads. When the 304 stainless steel ice-making heads come into contact with water, they freeze to form bullet ice. For example, the bullet ice evaporator used in a bullet ice-type ice maker disclosed in CN212227450U, and another example is an evaporator disclosed in CN215765867U. In order to overcome the problem of the steel pipe springing back when bending, the evaporator is designed by splicing and welding a cover plate and a base plate to form a main pipe. The ice-making heads are welded to the base plate, but the structure is still a bullet ice evaporator, that is, it includes a main pipe and multiple ice-making heads set on the main pipe.

[0003] However, existing bullet ice evaporators are all made of heat-conducting materials, such as 304 stainless steel pipes as main pipes and 304 stainless steel ice-making heads as ice-making heads. For example, an evaporator disclosed in CN215765867U has a base plate, cover plate, and bullet head made of stainless steel, while the insert is made of copper.

[0004] When the refrigerant flows through the main pipe, the ice-making head is constantly exchanging heat, resulting in a considerable loss of cooling capacity from the main pipe. This not only wastes energy but also makes it difficult to improve the icing efficiency of the ice-making head. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a bullet ice evaporator that is beneficial for saving energy and improving the icing efficiency of the ice-making head; and to provide an ice maker that uses the aforementioned bullet ice evaporator, which is beneficial for saving energy and improving the icing efficiency.

[0006] The technical solution of this utility model is: a bullet ice evaporator, including a main pipe and multiple ice-making heads disposed on the main pipe. The main pipe circulates refrigerant and delivers the refrigerant to the ice-making heads. The ice-making heads are made of thermally conductive material and are made of heat-insulating material. The main pipe is provided with a connecting hole on the lower side of the pipe, and an ice-making head is installed in each connecting hole.

[0007] With the above structure, this utility model has the following advantages:

[0008] This disclosure improves upon existing technology by using a pipe made of heat-insulating material as the main pipe. This pipe can be integral or composed of two or more pieces bonded together. In this way, the heat exchange when the refrigerant flows through the main pipe is greatly reduced compared to existing technologies. That is, the heat exchange of evaporation and heat absorption is significantly reduced when the refrigerant flows through the main pipe, thereby transferring more energy to the ice-making head. In other words, the heat exchange of evaporation and heat absorption mainly occurs in the ice-making head, thereby improving the icing efficiency of the ice-making head.

[0009] In summary, this disclosure is beneficial for saving energy and improving the icing efficiency of ice-making heads.

[0010] Preferably, the main pipe is made of plastic tubing.

[0011] As a preferred option, the ice-making head is made of stainless steel. Attached image description:

[0016] To better understand this application, various aspects of this application will be described in more detail below with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely illustrative of exemplary embodiments of this application and are not intended to limit the scope of this application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0017] In the accompanying drawings, the thickness, size, and shape of the objects have been slightly exaggerated for illustrative purposes. The drawings are for illustrative purposes only and are not drawn to scale.

[0018] It should also be understood that the terms “comprising,” “including,” “having,” “containing,” “comprise,” and “containing”, when used in this specification, indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0019] like Figures 1 to 3As shown, this disclosure proposes a bullet ice evaporator, including a main pipe 1 and a plurality of ice-making heads 2 disposed on the main pipe 1. The main pipe 1 circulates refrigerant and delivers the refrigerant to the ice-making heads 2. The ice-making heads 2 are cylindrical bodies made of thermally conductive material. The main pipe 1 is a pipe made of thermally insulating material. A connecting hole 3 is provided on the lower side of the pipe, and an ice-making head 2 is installed in each connecting hole 3.

[0020] This disclosure also proposes an ice maker, including a compressor, wherein the bullet ice evaporator is connected to the compressor.

[0021] When this invention is installed in an ice maker, the main pipe 1 is connected to the compressor via the inlet pipe 4 and the outlet pipe 5. The compressor pumps the refrigerant into the main pipe 1 through the inlet pipe 4 and guides it back to the compressor through the outlet pipe 5, thereby driving the compressor to circulate the refrigerant along the pipeline for refrigeration and ice making.

[0022] In some embodiments, the main pipe 1 is made of plastic, which not only has better thermal insulation performance but is also easy to manufacture. Of course, in addition to plastic, any other thermal insulation material suitable for this disclosure can be used in this disclosure.

[0023] The ice-making head 2 can be made of stainless steel and installed through the connecting hole 3. It can be connected by adhesive or other suitable connection methods, so that the refrigerant passes through these ice-making heads 2 in sequence.

[0024] When understanding this utility model, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that is understood, so I will not elaborate further here.

[0025] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
