[0002] The description in this part only provides background information related to the disclosure of the utility model and does not constitute prior art.

[0003] An ice maker is a refrigeration mechanical device that cools water through an evaporator by a refrigerant of a refrigeration system to generate ice. It adopts a refrigeration system with water as a carrier, and manufactures ice after passing through a certain device under the energized state. According to different principles and production methods of the evaporator, the shapes of the generated ice cubes are also different; generally, ice makers are classified into pellet ice makers, flake ice makers, cube ice makers, round ice makers, tube ice makers, shell ice makers, etc. according to the ice shape.

[0004] Most of the existing ice makers are set as single-system ice makers. Specifically, a single-system ice maker refers to a heat exchange system composed of only a set of compressors, pipelines and throttling device units in an ice maker. However, if higher ice-making production capacity needs to be satisfied, it is necessary to improve the refrigeration capacity of the compressor and other structures of the ice maker, which will significantly increase the cost of the ice maker and have worse safety. At the same time, the efficiency of the existing ice maker is relatively low, especially in the evaporator area, and it is difficult to achieve efficient heat exchange.

[0033] Please refer to Figure 1-2 , an independent dual-system ice maker for this embodiment; wherein the independent dual-system ice maker includes:

[0034] A frame 1, the frame 1 includes a first side and a second side arranged vertically, and the first side and the second side are arranged opposite to each other;

[0035] A first evaporator 2a and a second evaporator 2b, the first evaporator 2a and the second evaporator 2b are arranged on the first side;

[0036] A first condenser 3a and a second condenser 3b, the first condenser 3a and the second condenser 3b are arranged on the second side;

[0037] A first compressor 4a and a second compressor 4b, the first compressor 4a and the second compressor 4b are arranged between the first side and the second side;

[0038] A water tank 5 and a water pipe 6, the water tank 5 is arranged at the bottom of the frame 1, one end of the water pipe 6 is connected to the water tank 5, and the other end leads to the tops of the first evaporator 2a and the second evaporator 2b;

[0039] Wherein, the outlet of the first compressor 4a is connected to the first condenser 3a, the first condenser 3a is connected to the first evaporator 2a after passing through a first throttling device 7a, and the first evaporator 2a is connected to the inlet of the first compressor 4a; the outlet of the second compressor 4b is connected to the second condenser 3b, the second condenser 3b is connected to the second evaporator 2b after passing through a second throttling device 7b, and the second evaporator 2b is connected to the inlet of the second compressor 4b;

[0040] A fixing frame 9 is provided on the first side surface. The center of the fixing frame 9 includes a partition frame 91. The first evaporator 2a and the second evaporator 2b are arranged in the fixing frame 9 on both sides of the partition frame 91 in an up-and-down stacked manner.

[0041] For the above structure, during installation, a support plate can be arranged between the first compressor 4a and the second compressor 4b, and the first compressor 4a and the second compressor 4b are vertically placed on a narrow side of the frame 1. Then, when installing the first evaporator 2a and the second evaporator 2b, the first evaporator 2a and the second evaporator 2b are placed corresponding to each other up and down, and the sizes of the first evaporator 2a and the second evaporator 2b are matched, so that one side of the first evaporator 2a is adjacent to the second evaporator 2b, and the first evaporator 2a is supported on the partition frame 91, and the second evaporator 2b is arranged at the bottom of the partition frame 91. The first condenser 3a and the second condenser 3b are arranged on the second side surface corresponding to the first evaporator 2a and the second evaporator 2b, so that a relatively spacious pipeline organization space is formed between the first side surface and the second side surface in this system, and the first throttling device 7a and the second throttling device 7b for controlling the refrigerant heat exchange are exactly arranged in the area where the frame 1 avoids the pipeline.

[0042] With the above structure, during use, the operator only needs to fill the water tank 5 with a sufficient amount of water, start the external water pump to direct the water in the water tank 5 to the areas of the first evaporator 2a and the second evaporator 2b through the water pipe 6, and at the same time start the first compressor 4a and the second compressor 4b to run. During the operation process, the first evaporator 2a and the second evaporator 2b are respectively cooled, so that the normal temperature water flowing through the first evaporator 2a and the second evaporator 2b is cooled. Specifically, the water gradually forms ice cubes in the ice-making grids adjacent to one side of the first evaporator 2a and the second evaporator 2b. After the ice cubes are completely formed, devices such as an ice pusher are used to make the ice cubes fall off into the ice collection tank at the bottom of the first evaporator 2a and the second evaporator 2b, completing the ice-making process of this independent dual-system ice maker.

[0043] In the above process, the first evaporator 2a, the first condenser 3a, and the first compressor 4a form an independent heat exchange system. At the same time, the second evaporator 2b, the second condenser 3b, the second compressor 4b, and the second throttling device 7b form another independent heat exchange system. The two systems operate synchronously. Therefore, the loss of the ice-making function of the entire system caused by the damage of a single component is avoided. That is to say, when one of the systems stops operating, the other system continues to work. At the same time, the first evaporator 2a and the second evaporator 2b are stacked, and the first evaporator 2a and the second evaporator 2b share the side of a common rack 1. After the ice cubes are made, they jointly fall into the cabin in the same direction, significantly saving space. Moreover, the first evaporator 2a and the second evaporator 2b play a role in maintaining the cooling temperature of each other for the ice-making grids on one side for generating ice cubes, having high energy-saving performance. And with the setting of the fixed frame 9, the first evaporator 2a and the second evaporator 2b adjacent to it are installed on both sides of the partition frame 91, so that the first evaporator 2a, the second evaporator 2b, and the ice-making grids and other structures on one side are actually in a state of being quickly detachable, and different types of ice-making grids can be installed according to needs to meet various ice-making requirements.

[0044] Furthermore, the first compressor 4a and the second compressor 4b are arranged in an up-and-down stacked manner between the first side and the second side, and the first condenser 3a and the second condenser 3b are arranged in an up-and-down stacked manner on the second side. Specifically, the first evaporator 2a, the first condenser 3a, and the first compressor 4a are jointly arranged on the upper side of the rack 1, and the second evaporator 2b, the second condenser 3b, and the second compressor 4b are jointly arranged on the lower side of the rack 1. That is to say, in this embodiment, a set of heat exchange system composed of the first evaporator 2a, the first condenser 3a, and the first compressor 4a is arranged on the top of the rack 1, and a set of heat exchange system composed of the second evaporator 2b, the second condenser 3b, and the second compressor 4b is arranged on the bottom of the rack 1, and the structures at the corresponding positions of the top and the bottom are in one-to-one correspondence, so as to occupy less space and leave a complete rectangular space between the racks 1 for facilitating the organization of pipelines.

[0045] Further, a ice guiding groove 8 is provided at the bottom of the first evaporator 2a, and the width dimension of the ice guiding groove 8 matches the width dimension of the first evaporator 2a. In this embodiment, based on the fact that the first compressor 4a and the second compressor 4b are stacked vertically, the ice guiding groove 8 is provided at the bottom of the first evaporator 2a and is disposed adjacent to the second evaporator 2b. Specifically, the top of the ice guiding groove 8 closely adheres to the edge of the ice making grid at the bottom of the first evaporator 2a, and the opening gradually expands, so that the ice cubes detached from the ice making grid of the first evaporator 2a can all fall intact into the pipeline of the ice guiding groove 8. The bottom of the ice guiding groove 8 is connected to an ice collecting groove for placing ice cubes, so that even if the first evaporator 2a and the second evaporator 2b are separate independent structures, the ice cubes in the ice making grids on one side can all fall into the same area together, facilitating the operator to collect the ice cubes.

[0046] Further, the first throttling device 7a is disposed on one side of the frame 1 away from the first evaporator 2a, the second throttling device 7b is disposed on one side of the frame 1 away from the second evaporator 2b, and the first throttling device 7a and the second throttling device 7b are stacked vertically and disposed on the same side of the frame 1. With the above structure, a relatively large space is left vacant at the middle position of the frame 1, so as to facilitate the organization of other structures such as water pumps, ice pushing devices and sensors.

[0047] The content disclosed above is only the preferred feasible embodiment of the present utility model, and does not limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present utility model are included in the scope of the patent application of the present utility model.

[0048] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0049] Although the present application is depicted through embodiments, those of ordinary skill in the art know that the present application has many variations and changes without departing from the spirit of the present application. It is hoped that the appended embodiments include these variations and changes without departing from the present application.
