Description

Technical Field

[0001] This utility model relates to the technical field of ice makers, and specifically to an evaporator for an ice maker with an exhaust structure. Background Technology

[0002] In existing ice makers, water is injected into the inner ice-making tank through the inlet pipe. The liquid in the inner tank freezes into ice along the inner wall of the tank through heat exchange. Driven by a motor, the ice blade screw rotates, scraping the frozen ice layer into smaller pieces. The blades of the ice blade screw, rotating with the screw, transport the smaller pieces of ice upwards to the extrusion head. The smaller pieces of ice are discharged through the extrusion holes of the extrusion head, forming the final desired ice block shape.

[0003] However, because the water contains air, the ice blade screw will squeeze the air out during the ice-making process in the ice-making inner barrel, forming a certain amount of gas inside the ice-making inner barrel. If this gas accumulates to a large amount, it will cause a relatively large air bubble in the inner cavity of the ice-making inner barrel, which will affect the water intake of the ice-making inner barrel and affect the ice-making of the entire ice-making inner barrel, thus causing the cylinder to freeze. Utility Model Content

[0004] This invention proposes an evaporator for an ice maker with a venting structure. The venting structure, integrated into the ice blade screw, effectively solves the problem of gas accumulation inside the ice-making inner barrel. During ice making, when gas is generated inside the inner barrel, it is expelled along the venting structure, preventing the formation of large air bubbles and ensuring smooth water intake, thus preventing cylinder freezing. This venting structure is integrated into the ice blade screw, eliminating the need for additional venting components, resulting in a compact structure that does not affect the original ice-making efficiency. The active venting mechanism of the structure can adapt to different ice-making conditions, significantly improving stability, especially during high-frequency ice making.

[0005] An ice maker evaporator with an exhaust structure designed for this purpose includes an ice blade screw rotatably mounted on the inner ice barrel for scraping ice from the inner wall of the inner ice barrel, and the ice blade screw is provided with an exhaust structure for discharging gas from inside the inner ice barrel.

[0006] The exhaust structure is located near the ice outlet of the inner ice-making tank.

[0007] The ice-making inner barrel is provided with a water inlet, and the air inlet and outlet of the exhaust structure are both far away from the water inlet, and the air outlet of the exhaust structure is located outside the ice-making inner barrel.

[0008] The exhaust structure includes an air inlet located on the side of the ice blade screw. The air inlet is connected to the ice-making inner barrel and is located away from the water inlet of the ice-making inner barrel. The air inlet is positioned opposite to the ice-pushing outlet of the ice blade screw.

[0009] The ice blade screw includes a rod body, one end of which is located outside the ice-making inner barrel and is provided with an ice-penetrating head. The ice-penetrating head is provided with an air outlet that forms an exhaust structure.

[0010] The air outlet runs vertically through the top and bottom of the ice-removing head, and the inner diameter of the air outlet at the top of the ice-removing head gradually increases towards the outside of the ice-removing head.

[0011] The exhaust structure includes an exhaust channel disposed within the rod body. The exhaust channel is disposed within the rod body along the length direction of the rod body, with one end of the exhaust channel connected to an air inlet and the other end of the exhaust channel connected to an air outlet.

[0012] The air intake direction of the air inlet and the exhaust direction of the exhaust channel are not parallel and form an angle A.

[0013] The ice blade screw is provided with a transverse air intake channel. One end of the air intake channel extends transversely to connect to the exhaust channel, and the other end of the air intake channel extends transversely to connect to the air inlet.

[0014] The shaft of the ice blade screw and the ice-gripping head are coaxially arranged, and the air outlet and the exhaust channel are connected and coaxially arranged.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] The venting structure integrated into the ice blade screw effectively solves the problem of gas accumulation inside the ice-making cylinder. During ice making, when gas is generated inside the ice-making cylinder, it is expelled along the venting structure, preventing the formation of large air bubbles and ensuring smooth water intake, thus preventing cylinder freezing. This venting structure is integrated into the ice blade screw, eliminating the need for additional venting components, resulting in a compact structure that does not affect the original ice-making efficiency. The active venting mechanism of the structure can adapt to different ice-making conditions, significantly improving stability, especially during high-frequency ice making.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0023] See Figures 1-4 An ice maker evaporator with an exhaust structure includes an ice blade screw 2 rotatably mounted on an inner ice barrel 1 for scraping ice from the inner wall of the inner ice barrel 1, and an exhaust structure 3 on the ice blade screw 2 for discharging gas from inside the inner ice barrel 1.

[0024] The venting structure 3 installed on the ice blade screw 2 effectively solves the problem of gas accumulation inside the ice-making inner barrel 1. During ice making, when gas is generated inside the ice-making inner barrel 1, the gas is discharged along the venting structure 3, preventing gas from accumulating and forming large bubbles inside the ice-making inner barrel 1, thus ensuring smooth water intake and preventing cylinder freezing. This venting structure 3 is integrated into the ice blade screw 2, eliminating the need for additional venting components, resulting in a compact structure that does not affect the original ice-making efficiency. The active venting mechanism of the venting structure 3 can adapt to different ice-making conditions, significantly improving stability, especially during high-frequency ice making.

[0025] The exhaust structure 3 is located near the ice outlet of the ice-making inner barrel 1.

[0026] The exhaust structure 3 is positioned near the ice outlet of the ice-making inner barrel 1, allowing for targeted discharge of concentrated gases released during the ice-extrusion process. Since the ice outlet is a critical area where the ice blade screw 2 crushes ice, gas tends to accumulate there. The proximity of the exhaust structure 3 quickly guides the gas, preventing large bubbles from forming within the ice-making inner barrel 1. This design optimizes the gas discharge path, coordinating exhaust with the ice-extrusion action. It does not interfere with the normal ice-extrusion of the extrusion head, while maintaining pressure balance within the ice-making inner barrel 1 through efficient localized exhaust, further reducing the risk of cylinder freezing and significantly improving stability during high-frequency ice making.

[0027] The ice-making inner barrel 1 is provided with a water inlet 9, and the air inlet and outlet of the exhaust structure 3 are both far away from the water inlet 9, and the air outlet of the exhaust structure 3 is located outside the ice-making inner barrel 1.

[0028] The air inlet and outlet of the exhaust structure 3 are both far from the water inlet 9, and the outlet is located outside the ice-making inner tank 1, which prevents the water flow from the water inlet 9 from interfering with the exhaust process. By isolating the exhaust path from the water inlet area, backflow of water or gas is avoided, ensuring efficient unidirectional exhaust. At the same time, the external exhaust design allows the gas to be directly discharged into the environment, effectively eliminating the accumulation of gas inside the ice-making inner tank 1.

[0029] The exhaust structure 3 includes an air inlet 4 located on the side of the ice blade screw 2. The air inlet 4 is connected to the ice-making inner barrel 1 and is located away from the water inlet end of the ice-making inner barrel 1. The air inlet 4 is located opposite to the ice-pushing outlet point of the ice blade screw 2.

[0030] The air inlet 4 of the exhaust structure 3 is located on the side of the ice blade screw 2 and away from the water inlet of the ice-making inner barrel 1, enabling it to accurately capture the gas accumulated on the upper part of the ice-making inner barrel 1. Since gas density is lower than water, the high-position design of the air inlet 4 prioritizes the discharge of gas rather than liquid, preventing blockage of the exhaust channel 6. When the ice blade screw 2 rotates, the air inlet 4 dynamically covers the inner wall area of ​​the ice-making inner barrel 1, creating an active scavenging effect and enhancing exhaust efficiency. This structure is simple and reliable, requiring no external power source; continuous exhaust is achieved solely through the movement of the ice blade screw 2, reducing energy consumption and maintenance costs. The air inlet 4 is positioned opposite to the ice-pushing outlet point of the ice blade screw 2 to prevent blockage of the air inlet 4 when the ice blade screw 2 is discharging ice.

[0031] The ice blade screw 2 includes a rod body 5, one end of which is located outside the ice-making inner barrel 1 and is provided with an ice-removing head 8. The ice-removing head 8 is provided with an air outlet 7 forming an exhaust structure 3.

[0032] The blade screw 2's shaft 5 extends to the outside of the ice-making inner barrel 1, and an ice-dispensing head 8 with an air outlet 7 is provided at its end, achieving integrated venting and ice dispensing functions. As the terminal component of the blade screw 2, the ice-dispensing head 8 directly exhausts air through its air outlet 7, shortening the gas emission path and reducing flow resistance. The linkage design between the shaft 5 and the ice-dispensing head 8 ensures that the venting process is synchronized with the ice-making rhythm, preventing gas stagnation.

[0033] The air outlet 7 extends vertically through the top and bottom of the ice-removing head 8, ensuring that the air outlet 7 is connected to the exhaust channel 6. The inner diameter of the air outlet 7 at the top of the ice-removing head 8 gradually increases towards the outside of the ice-removing head 8 to ensure smooth exhaust.

[0034] The exhaust structure 3 includes an exhaust channel 6 disposed within the rod body 5. The exhaust channel 6 is disposed within the rod body 5 along the length direction of the rod body 5. One end of the exhaust channel 6 is connected to the air inlet 4, and the other end of the exhaust channel 6 is connected to the air outlet 7.

[0035] The air intake 4 is positioned in a non-parallel manner with the exhaust channel 6, forming an angle A.

[0036] The direction of the air inlet 4 is at a non-parallel angle A with the direction of the exhaust channel 6, forming an airflow guiding structure that enhances gas intake efficiency. The angle A design causes the air inlet 4 to generate a negative pressure effect when rotating, actively drawing in the dispersed gas inside the ice-making inner barrel 1.

[0037] In this embodiment, a filter screen may be provided at the air inlet 4 to prevent ice from entering along the air inlet 4.

[0038] The ice blade screw 2 is provided with a transverse air intake channel 10. One end of the air intake channel 10 extends transversely to connect to the exhaust channel 6, and the other end of the air intake channel 10 extends transversely to connect to the air intake port 4.

[0039] The shaft 5 of the ice blade screw 2 and the ice-gripping head 8 are coaxially arranged, and the air outlet 7 is connected to the exhaust channel 6 and is coaxially arranged.

[0040] In this embodiment, the ice-making inner barrel 1 is provided with an ice-squeezing head 11, and the ice-squeezing head 11 is provided with an ice-squeezing hole 12. The ice-squeezing head 11 is sleeved on the top position of the ice-making inner barrel 1, and the ice-making inner barrel 1 is provided with a water inlet connector 13 near its lower part. The water inlet connector 13 is provided corresponding to the water inlet 9.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
