Description

Technical Field

[0001] The utility model relates to the technical field of ice making machines, and particularly relates to an ice making module. Background Technique

[0002] An ice making machine is a refrigeration mechanical device that cools water through an evaporator with a refrigerant in a refrigeration system, uses the refrigeration system with water as a carrier, and makes ice after passing through a certain device under the energized state. According to the principle of the evaporator and different production methods, the shapes of the generated ice cubes are also different.

[0003] When the existing ice making machine is working, water is injected into the water expansion tube, and then a refrigerant is added into the copper tube outside the water expansion tube to achieve the effect of evaporation refrigeration, so that the water in the water expansion tube quickly freezes into ice.

[0004] However, in the actual use process of the existing refrigerating machine, people will find that since the copper tube is arranged outside the water expansion tube, when injecting the refrigerant, the refrigerant needs to flow along the copper tube and then conduct the temperature to the evaporation barrel through the copper tube, which will greatly increase the evaporation time and thus reduce the evaporation efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide an ice making module to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an ice making module, including an evaporation barrel, a water expansion tube and a screw. The water expansion tube is sleeved outside the evaporation barrel. A refrigerant inlet and a refrigerant outlet are arranged at positions close to both ends on the side of the water expansion tube. One end of the evaporation barrel is provided with a planetary gear speed reducer and the other end is provided with a discharge end cover. A water injection port is arranged at a position of the evaporation barrel close to the planetary gear speed reducer. The screw is arranged inside the evaporation barrel. The screw is connected to the output end of the planetary gear speed reducer. The evaporation barrel is fixedly connected to the planetary gear speed reducer. The input end of the planetary gear speed reducer is connected with a DC brushless motor. One end of the screw passes through the discharge end cover through a connecting shaft and is connected with an ice pushing cap. A plurality of through discharge ports are opened on the discharge end cover. By injecting water into the evaporation barrel and injecting a refrigerant between the evaporation barrel and the water expansion tube through the refrigerant inlet, the refrigerant is in direct contact with the evaporation barrel, so that the water in the evaporation barrel quickly freezes into ice, increasing the evaporation area of the refrigerant, and achieving a 1 / 3 reduction in volume for the same ice production; using a DC brushless motor plus a planetary gear speed reducer reduces energy consumption, improves work efficiency and enhances torque at the same time.

[0007] Preferably, the inner wall of the evaporation barrel is provided with threads opposite to the spiral direction of the screw. The reverse threads on the inner wall increase the evaporation area and ensure that the ice wall will not slip as the screw rotates.

[0008] Preferably, a foaming layer is sleeved outside the hydro-expansion tube. The foaming layer is 110g high-density foaming, which realizes high strength while keeping the cold quantity from dissipating.

[0009] Preferably, spiral grooves are provided on the side wall of the hydro-expansion tube. The side wall of the hydro-expansion tube is set to be spiral to ensure the integrity of evaporation and improve the evaporation effect.

[0010] Preferably, the discharge ports are annularly and regularly distributed on the discharge end cover, and the shape of the discharge ports can be prefabricated.

[0011] Preferably, one side of the ice-pushing cap close to the discharge end cover is conical, and ice-pushing blocks are arranged on the side of the ice-pushing cap. The ice-pushing cap and the ice-pushing blocks are used to cut the ice cubes and send the ice cubes into the ice storage bucket at the same time.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By injecting a refrigerant between the evaporation barrel and the hydro-expansion tube, the present utility model enables the refrigerant to be in direct contact with the evaporation barrel, thereby increasing the evaporation area of the refrigerant, realizing rapid evaporation, and improving the evaporation effect at the same time. Anti-thread is provided on the inner wall of the evaporation barrel to ensure that the ice wall will not slip as the screw rotates.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: an ice making module, including an evaporation barrel 3, a water expansion tube 4, and a screw 8. The water expansion tube 4 is sleeved outside the evaporation barrel 3. A refrigerant inlet 401 and a refrigerant outlet 402 are provided at positions near both ends of the side of the water expansion tube 4. One end of the evaporation barrel 3 is provided with a planetary gear reduction box 1, and the other end is provided with a discharge end cover 5. A water injection port 301 is provided at a position of the evaporation barrel 3 near the planetary gear reduction box 1. The screw 8 is arranged inside the evaporation barrel 3, and the screw 8 is connected to the output end of the planetary gear reduction box 1. The evaporation barrel 3 is fixedly connected to the planetary gear reduction box 1. The input end of the planetary gear reduction box 1 is connected to a DC brushless motor 2. One end of the screw 8 passes through the discharge end cover 5 through a connecting shaft and is connected to an ice pushing cap 6. A plurality of through discharge ports 501 are opened on the discharge end cover 5. By injecting water into the evaporation barrel 3 and injecting a refrigerant between the evaporation barrel 3 and the water expansion tube 4 through the refrigerant inlet 401, the refrigerant is in direct contact with the evaporation barrel 3, so that the water in the evaporation barrel 3 evaporates and freezes quickly, increasing the evaporation area of the refrigerant, and reducing the volume by 1 / 3 for the same ice production; using a DC brushless motor plus a planetary gear reduction box reduces energy consumption, improves work efficiency, and enhances torque at the same time.

[0023] Furthermore, the inner wall of the evaporation barrel 3 is provided with threads opposite to the spiral direction of the screw 8. While increasing the evaporation area, the reverse threads on the inner wall ensure that the ice wall does not slip as the screw 8 rotates.

[0024] Furthermore, a foaming layer 7 is sleeved outside the water expansion tube 4. The foaming layer 7 is 110g high-density foaming, which realizes high strength while retaining the cold quantity without loss.

[0025] Furthermore, spiral grooves are provided on the side wall of the water expansion tube 4. Setting the side wall of the water expansion tube 4 in a spiral shape ensures the integrity of evaporation and improves the evaporation effect.

[0026] Furthermore, the discharge ports 501 are annularly and integrally distributed on the discharge end cover 5, and the shape of the discharge ports 501 can be prefabricated.

[0027] Furthermore, one side of the ice-pushing cap 6 close to the discharge end cover 5 is conical, and a pushing block 601 is provided on the side of the ice-pushing cap 6. The ice-pushing cap 6 and the pushing block 601 are used to cut the ice cubes and send the cut ice cubes into the ice storage barrel at the same time.

[0028] In summary, when the device is in use, only need to start the DC brushless motor 2, so that the DC brushless motor 2 drives the screw 8 to rotate through the planetary gear speed reducer 1. While the screw 8 rotates, it drives the ice-pushing cap 6 to rotate. Then, water is injected into the evaporation barrel 3. At the same time, a refrigerant is injected between the water expansion tube 4 and the evaporation barrel 3 through the refrigerant inlet 401, so that the refrigerant directly contacts the evaporation barrel 3, causing the water inside the evaporation barrel 3 to freeze quickly. And the foaming layer 7 provided outside the water expansion tube 4 can retain the cold quantity without loss. At the same time, as the screw 8 rotates, the formed ice will be extruded from the discharge port 501 of the discharge end cover 5, and the extruded ice cubes will be cut as the ice-pushing cap 6 rotates.

[0029] It should be noted that: the entire device is controlled by the total control button. Since the devices matched with the control button are common devices and belong to the existing mature technologies, the electrical connection relationship and the specific circuit structure are not described in detail here.
