[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0045] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0046] In some embodiments, please refer to the accompanying drawings. Figures 1-6A self-cleaning chiller includes a cabinet 1, a water tank 2, a circulating cooling mechanism 3, a cleaning mechanism 4, and a turbulence-disrupting mechanism 5. The water tank 2 is fixedly installed on the left side of the bottom of the cabinet 1 via a bracket. An inlet pipe for feeding water to be cooled into the water tank 2 is fixedly installed on the upper left side of the water tank 2. An outlet pipe for discharging cooled water is fixedly installed on the lower right side of the water tank 2. The right end of the outlet pipe passes through the right end of the cabinet 1 and extends to the right.

[0047] The cabinet 1 is equipped with a circulating cooling mechanism 3 for cooling the water in the water tank 2.

[0048] like Figure 2 and Figure 3 As shown, the circulating cooling mechanism 3 includes a compressor 31, a condenser 32, a spiral evaporator 33, and a fan 34; the compressor 31 is fixedly installed on the right side of the bottom of the cabinet 1; the condenser 32 is fixedly installed on the inner wall of the rear side of the cabinet 1; the feed end of the spiral evaporator 33 is fixedly connected to the upper rear end of the water tank 2; the discharge end of the spiral evaporator 33 is fixedly connected to the lower front end of the water tank 2.

[0049] A connecting pipe is fixedly installed between the compressor 31 and the condenser 32, so that the compressor 31 and the condenser 32 are connected.

[0050] A connecting pipe is fixedly installed between the condenser 32 and the spiral evaporator 33, so that the condenser 32 and the spiral evaporator 33 are connected.

[0051] A connecting pipe is also fixedly installed between the spiral evaporator 33 and the compressor 31, so that the spiral evaporator 33 and the compressor 31 are connected.

[0052] The casings of the two fans 34 are fixedly installed at the rear end of the condenser 32;

[0053] The compressor 31 contains refrigerant;

[0054] An expansion valve is also fixedly installed on the connecting pipe between the condenser 32 and the spiral evaporator 33.

[0055] The interior of the water tank 2 is equipped with a cleaning mechanism 4 for cleaning the spiral tube of the spiral evaporator 33;

[0056] like Figure 4 As shown, the cleaning mechanism 4 includes an upward control component 41, a downward control component 42, a limiting component, and a moving component; the upward control component 41 and the downward control component 42 have the same structure but different installation positions; the upward control component 41 is installed on the upper side of the water tank 2; the downward control component 42 is installed on the lower side of the water tank 2.

[0057] The upward control component 41 and the downward control component 42 are connected to the limit component;

[0058] The limiting component is used to control the moving component to move up and down along a spiral trajectory; the moving component used to clean the outer surface of the spiral tube of the spiral evaporator 33 is connected to the limiting component;

[0059] The active component is equipped with a turbulence mechanism 5 for controlling the water flow near the spiral evaporator 33 and improving the cooling effect;

[0060] In this invention, the water to be cooled flows into the water tank 2 through the inlet pipe installed at the left end of the water tank 2; then the compressor 31 works, which compresses the refrigerant into high-pressure gas, and then the high-pressure gas enters the condenser 32 through the connecting pipe. At this time, the fan 34 works, which causes the refrigerant entering the condenser 32 to exchange heat. At this time, the refrigerant releases heat and condenses into liquid, which flows into the expansion valve through the connecting pipe. Then the liquid refrigerant is depressurized through the expansion valve and becomes a low-temperature, low-pressure mixture of liquid and gas, which flows into the spiral evaporator 33. Then the refrigerant can absorb the heat of the water in the water tank 2 and evaporate into gas again, which returns to the compressor 31 through the connecting pipe, thereby completing the circulating cooling of the water in the water tank 2.

[0061] When cooling is performed, if the water quality is poor and the temperature difference between the water and the outer surface of the spiral tube in the spiral evaporator 33 is large, scale is easily generated on the spiral tube in the spiral evaporator 33.

[0062] At this time, the upward control component 41 and the downward control component 42 work simultaneously, causing the limit component to move upward. During the movement, the operation of the limit component will also cause the movable component to move upward along the outer surface of the spiral tube in the spiral evaporator 33 in a spiral trajectory.

[0063] During the movement of the movable component, the outer surface of the spiral tube in the spiral evaporator 33 is cleaned. After the movable component moves to the upper side of the spiral evaporator 33, the upward control component 41 and the downward control component 42 work again to make the limiting component and the movable component move down. By repeating the above operation, the outer surface of the spiral tube in the spiral evaporator 33 can be cleaned in all directions, reducing the scale residue in the water tank 2 and ensuring the cooling quality of the water. When the movable component moves along the surface of the spiral tube of the spiral evaporator 33, the movable component will also control the movement of the turbulence mechanism 5. At this time, the operation of the turbulence mechanism 5 will disturb the water near the outer surface of the spiral evaporator 33 to flow, thereby improving the cooling efficiency of the water.

[0064] like Figure 4As shown, both the upward control component 41 and the downward control component 42 are composed of a rotating shaft 43, a winding reel 44, a drive motor 45, and a cable 46; the front and rear ends of the rotating shaft 43 of the upward control component 41 are rotatably mounted on the upper side of the front and rear inner walls of the water tank 2; the front and rear ends of the rotating shaft 43 of the downward control component 42 are rotatably mounted on the lower side of the front and rear inner walls of the water tank 2.

[0065] A winding reel 44 is fixedly installed in the middle of the rotating shaft 43;

[0066] The drive motor 45 is fixedly installed on the outer wall of the water tank 2; and the output end of the drive motor 45 is fixedly connected to the rotating shaft 43.

[0067] One end of the cable 46 is fixedly connected to the inner ring of the winding reel 44; the other end of the cable 46 is connected to the limiting component.

[0068] like Figure 5 and Figure 6 As shown, the limiting assembly includes a rotating ring 47, a fixed shaft 412, and a fixed cylinder 414; the upper and lower ends of the fixed shaft 412 are fixedly connected to the rear inner wall of the water tank 2 via brackets; a guide thread groove 413 is provided on the outer end of the fixed shaft 412; a ball bearing that is slidably connected to the guide thread groove 413 is installed inside the fixed cylinder 414; and the fixed cylinder 414 is slidably connected to the fixed shaft 412; the rotating ring 47 is symmetrically rotated and installed at the upper and lower ends of the fixed cylinder 414.

[0069] The other end of the cable 46 is fixedly connected to the rotating ring 47;

[0070] The fixed cylinder 414 is connected to the movable component;

[0071] The pitch of the guide thread groove 413 is the same as the pitch of the spiral tube of the spiral evaporator 33;

[0072] like Figure 5 As shown, the movable component includes a connecting plate 48, a movable plate 49, a fixing ring 410, and guide rollers 411; the right side of the connecting plate 48 is fixedly connected to the outer wall of the fixed cylinder 414; the left side of the connecting plate 48 is fixedly connected to the movable plate 49; guide rollers 411 that are rotatably mounted on the left and right sides of the inner top end of the movable plate 49 and are rolledly connected to the outer surface of the spiral evaporator 33; a fixing ring 410 is fixedly mounted on the front side of the inner top end of the movable plate 49.

[0073] The inner ring of the fixing ring 410 is fixedly equipped with bristles; the bristles are evenly distributed in a circumferential array at equal intervals in the inner ring of the fixing ring 410.

[0074] Guide roller 411 is connected to the turbulence mechanism 5;

[0075] like Figure 5As shown, the turbulence mechanism 5 includes a driven shaft 51 and rotating blades 52; the driven shaft 51 is fixedly installed at the lower end of the guide roller 411; a plurality of rotating blades 52 are fixedly installed at the lower end of the driven shaft 51; the rotating blades 52 are evenly distributed in a circular array on the driven shaft 51.

[0076] In this invention, during cooling, the drive motor 45 of the upward control component 41 operates, driving the rotating shaft 43 to rotate. The rotation of the rotating shaft 43 drives the take-up reel 44 to rotate, which in turn pulls the cable 46 to perform a winding action. At the same time, the drive motor 45 of the downward control component 42 operates, driving the rotating shaft 43 to rotate. The rotation of the rotating shaft 43 drives the take-up reel 44 to rotate, and the take-up reel 44 of the upward control component 41 and the take-up reel 44 of the downward control component 42 rotate in opposite directions. At this time, the take-up reel 44 of the downward control component 42 will unwind the cable 46, causing the cable 46 to move upward.

[0077] When the cable 46 moves upward, it will drive the rotating ring 47 and the fixed cylinder 414 to move upward together. At this time, the ball installed inside the fixed cylinder 414 will slide along the guide thread groove 413 opened at the outer end of the fixed shaft 412. Since the pitch of the guide thread groove 413 is the same as the pitch of the spiral tube of the spiral evaporator 33, the fixed cylinder 414 will drive the moving plate 49 and the connecting plate 48 to move upward along the fixed shaft 412 in a spiral trajectory. At the same time, under the friction force generated by the outer surface of the spiral tube in the spiral evaporator 33 on the guide roller 411, the guide roller 411 will move along the outer surface of the spiral evaporator 33 along the moving plate 49 and the connecting plate 48 in a spiral trajectory.

[0078] As the fixed cylinder 414 moves upward, the rotating ring 47 will rotate, so that the cable 46 always has an upward traction force on the fixed cylinder 414; and prevent the cable 46 from getting tangled.

[0079] Furthermore, during the movement of the moving plate 49, the bristles installed on the inner ring of the fixing ring 410 will clean the outer surface of the spiral evaporator 33 to prevent scale buildup.

[0080] Similarly, when the moving plate 49 moves to the upper side of the spiral tube in the spiral evaporator 33, the drive motor 45 of the upward control component 41 works to unwind one end of the cable 46, and the drive motor 45 of the downward control component 42 works to wind up the other end of the cable 46. At this time, the cable 46 will move downward, causing the moving plate 49 to move downward along the surface of the spiral tube of the spiral evaporator 33.

[0081] Furthermore, when the guide roller 411 rotates, it will drive the driven shaft 51 to rotate. The rotation of the driven shaft 51 will drive multiple rotating blades 52 to rotate together. The rotation of the rotating blades 52 will disturb the water flow near the outer surface of the spiral evaporator 33, thereby improving the water cooling efficiency.

[0082] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
