The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Please refer to the attached Figure 1 , which shows a refrigeration device that effectively prevents ice from forming and avoids damage to the compressor caused by ice. The controllable magnetic attraction characteristics of the electromagnet are utilized, a float is added inside the water tank, and the float is controlled to rise and fall by the electromagnet, thereby causing water flow disturbance in the refrigeration water tank, making the water temperature in the water tank dynamically uniform under the turbulent effect, overcoming the phenomenon of easy ice formation caused by local low temperature, thereby obtaining a refrigeration device that can effectively prevent ice formation.

[0028] in Figure 1 and Figure 2 The present invention shows an overall anti-icing refrigeration device, including an outer water tank 10 and an inner water tank 20, wherein refrigeration elements are evenly distributed on the outer wall of the inner water tank 20. Specifically, in the implementation of the product, the refrigeration element is actually a refrigeration tube 30, wherein the outer water tank 10 is filled with water, and the refrigeration tube 30 is coiled on the outer wall of the inner water tank 20, and there is a gap space between the bottom of the inner water tank 20 and the outer water tank 10, and a float disturbance structure 40 is provided in the gap space.

[0029] The floating ball disturbance structure 40 includes a floating ball upright rod 41, a floating ball 42, and an electromagnet 43. The floating ball upright rod 41 is arranged at the bottom of the outer water tank 10 and vertically faces the inner water tank 20. The floating ball 42 is penetrated by the floating ball upright rod 41 and is limited by the floating ball upright rod 41. A limiting piece for clamping the floating ball 42 is provided at the top of the floating ball upright rod 41. The electromagnet 43 is arranged at the bottom outside the outer water tank 10, and a ferromagnetic metal 421 attracted by magnetic force is embedded in the bottom of the floating ball 42. The working principle and process of the entire float disturbance structure 40 are as follows: when the electromagnet is not energized, no magnetic force is generated, and the float 42 floats to the top under normal buoyancy, and is limited to the highest position by the limiter of the float upright 41. When the electromagnet 43 is energized, a magnetic force is generated to adsorb the float 42 with ferromagnetic metal 421, and move the float 42 downward from the highest position until it is attached to the bottom of the outer water tank 10. This up and down floating process causes the water in the outer water tank to be mixed and turbulent to uniform the water temperature.

[0030] Based on this process, there is no doubt that the float 42 should be designed to be hollow and watertight inside to ensure that its density is less than that of water. When the electromagnet 43 is not energized, the float 42 floats to the upper limit position of the float rod 41.

[0031] Please refer to the attached Figure 4 , which shows the structure of the float 42, wherein the float 42 includes a central main body 422 and a float blade 423, wherein a vertical rod hole 425 is provided at the center of the central main body 422, the float blade 423 has a plurality of petals evenly distributed on the outer circumference of the main body 422, and the float blade 423 has a plurality of through holes 424.

[0032] Please refer to the attached Figure 3 The outer water tank 10 includes an outer water tank drain port 11 and an outer water tank water inlet 12. The outer water tank drain port 11 is arranged at the bottom of the outer water tank 10, and the outer water tank water inlet 12 is arranged at the top of the outer water tank 10. The process of water entering from the top and draining from the bottom is completed. An outer water tank exhaust port 14 is also arranged at the top of the outer water tank 10.

[0033] The inner water tank 20 is a cylinder, and an inner water tank water inlet 21 and an inner water tank water outlet 22 are provided on the top thereof.

[0034] The inner water tank 20 is also provided with an inner water tank pressure relief port 23 and an inner water tank air inlet 24, both of which are arranged at the top of the inner water tank 20. The inner water tank pressure relief port 23 can release the excessive pressure in the water tank, while the inner water tank air inlet 24 is used to inject gas into the water tank for pressurization when the pressure is insufficient.

[0035] The refrigeration element is arranged outside the inner water tank 20. The refrigeration element is actually one or more refrigeration pipes 30 spiraled on the outer circumferential wall of the inner water tank, and liquid refrigerant is poured into the refrigeration pipes 30. The water in the inner water tank is cooled by circulating refrigeration of the liquid refrigerant.

[0036] The refrigeration pipe 30 starts from the top of the inner water tank and winds to the bottom of the inner water tank, and leads out from the bottom to a straight pipe vertically upward from the bottom. The top where the winding starts is the refrigerant inlet 31, and the end of the straight pipe is the refrigerant outlet 32.

[0037] A temperature sensor 13 is provided at the bottom of the outer water tank 10 , and a water level sensor 15 is provided in the outer water tank 10 .

[0038] The anti-icing refrigeration device involved in the utility model utilizes the magnetic attraction of an electromagnet to adsorb a floating ball with ferromagnetic metal, and controls the floating ball to fluctuate in an external water tank, thereby causing a disturbance in the water flow in the refrigeration water tank, so that the water temperature in the water tank is dynamically uniform under the turbulent effect, overcoming the phenomenon of easy freezing caused by local excessively low temperature, thereby obtaining a refrigeration device that can effectively prevent freezing.
