DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figure 1-Figure 6 As shown, an air-energy water heater with anti-scaling function includes a water tank 1 for storing hot water, a cleaning brush 2 for cleaning the water tank 1, a driving ring 6 and a hot water pipe 7 for providing power to the cleaning brush 2, the cleaning brush 2 is provided with a tensioner 3 for elastically contacting the inner wall of the water tank 1, a fan blade 4 for stirring and a scraper 5 for removing stains on the inner wall of the water tank 1, the cleaning brush 2 is arranged at the inner center of the water tank 1, the driving ring 6 passes through the bottom of the water tank 1 and is connected to the center of the cleaning brush 2, the hot water pipe 7 is installed on both sides of the water tank 1, the cleaning brush 2 is annular, the tensioner 3 is arranged on the annular surface of the cleaning brush 2, the fan blade 4 array is arranged on the side of the driving ring 6 and is connected to the tensioner 3, and the scraper 5 is arranged on the outside of the cleaning brush 2.

[0026] The hot water pipe 7 is used to supply and discharge hot water to the water tank 1. When the water heater is cleaned, the hot water in the water tank 1 is first discharged and the hot water pipe 7 is closed to ensure the cleaning effect. The inside of the water tank 1 is cleaned by adding cleaning liquid to the water tank 1 and the driving ring 6 drives the cleaning brush 2 to avoid repeated opening of the water tank 1, which may affect its sealing and heat preservation capabilities. The driving ring 6 carries the cleaning brush 2 to perform eccentric wheel movement inside the water tank 1. Whenever it contacts the inner wall of the water tank 1, an impact force is generated. In order to prevent damage to the water tank 1 and the cleaning brush 2, a tensioner 3 is used to reduce the impact force and increase the contact force between the cleaning brush 2 and the inner wall of the water tank 1. The fan blade 4 is used to stir the cleaning liquid in the water tank 1 to improve the cleaning effect. The scraper 5 is used to increase the friction between the cleaning brush 2 and the inner wall of the water tank 1 to remove stubborn stains.

[0027] See also Figure 1 to Figure 4 As shown, the tensioner 3 is provided with a telescopic rod 31, a rolling ball 32 and a connecting rod 33. Two telescopic rods 31 are arranged on the annular surface of the cleaning brush 2. The rolling ball 32 is rollingly arranged on the top of the telescopic rod 31. The connecting rod 33 is installed between the two telescopic rods 31.

[0028] The rolling ball 32 ensures that the tensioner 3 can contact the inner wall of the water tank 1 at any angle and reduce the friction between the two. The telescopic rod 31 prevents the tensioner 3 from breaking in the collision. The connecting rod 33 enables the two telescopic rods 31 to have the ability to move synchronously.

[0029] See also Figure 4 and Figure 5 As shown, the groove 311 is arranged on the annular surface of the cleaning brush 2 , the bottom of the telescopic rod 31 is installed in the groove 311 , and the first spring 312 is surrounded on the outside of the telescopic rod 31 .

[0030] The groove 311 provides positioning for the installation of the telescopic rod 31, and the first spring 312 provides elasticity for the tensioner 3. When the tensioner 3 passes through the hot water pipe 7, it will temporarily lose contact friction with the inner wall of the water tank 1. Two telescopic rods 31 are used to prevent the tensioner 3 from getting stuck in the hot water pipe 7 and causing the movement of the cleaning brush 2 to stop.

[0031] See also Figure 4 As shown, the striker 331 is arranged at the center of the connecting rod 33 , the valve port 332 is arranged on the annular surface of the cleaning brush 2 and corresponds to the position of the striker 331 , the ring frame 334 is installed in the valve port 332 , and the second spring 333 is arranged on the ring frame 334 .

[0032] When the tensioner 3 is squeezed, the striker 331 on the connecting rod 33 hits the valve port 332, and the cleaning fluid stored in the fan blade 4 flows out from the valve port 332, which is convenient for cooperating with the scraper 5 to clean the stains on the inner wall of the water tank 1. The ring frame 334 provides positioning for installing the second spring 333, and the second spring 333 provides reset capability for the valve port 332, so that the valve port 332 can continuously discharge the cleaning fluid.

[0033] See also Figure 5 As shown, the fan blade 4 is provided with through holes 41 and a water storage tank 42 . The through holes 41 are arranged in an array on the surface of the fan blade 4 , and the water storage tank 42 is arranged in the fan blade 4 and communicated with the through holes 41 .

[0034] The through hole 41 is used to guide the cleaning liquid inside the water tank 1 to the water tank 42, and discharge it through the valve port 332 connected to the water tank 42, ensuring that the fan blade 4 can spray the cleaning liquid to the inner wall of the water tank 1 to improve the cleaning effect.

[0035] See also Figure 3 to Figure 6 As shown, a waterproof rod 61, a bias chamber 62 and a motor 63 are provided on the driving ring 6. The waterproof rod 61 is installed on the lower surface of the driving ring 6 and connected to the upper surface of the bias chamber 62. The motor 63 is installed at the bottom of the water tank 1 and connected to the lower surface of the bias chamber 62.

[0036] The waterproof rod 61 is used to prevent cleaning liquid or hot water from entering the bias chamber 62. The bias chamber 62 is used to drive the cleaning brush 2 to perform eccentric wheel movement, and the motor 63 provides power for the rotation of the driving ring 6.

[0037] See also Figure 6 As shown, a gear set 621 and a rotating shaft 622 are provided in the bias chamber 62 . There are two rotating shafts 622 , one connected to the driving ring 6 and the other connected to the motor 63 . The gear set 621 is provided at the connection of the two rotating shafts 622 .

[0038] The gear set 621 enables the cleaning brush 2 to rotate around its own center while eccentrically revolving, thereby preventing the same point on the cleaning brush 2 from continuously rubbing against the inner wall of the water tank 1. The rotating shaft 622 is used to transmit power to ensure the completion of the self-rotation and revolution of the cleaning brush 2.

[0039] See also Figure 1 and Figure 2 As shown, the switch valve 71 is arranged on the hot water pipe 7, the inlet 72 is arranged at the top of the water tank 1, and the sewage outlet 73 is arranged at the bottom of the water tank 1.

[0040] The switch valve 71 is used to open or close the hot water pipe 7, the inlet 72 is used to add cleaning liquid to the water tank 1, and the sewage outlet 73 discharges the sewage and impurities after cleaning into the water tank 1. Then, clean water is added from the inlet 72 for secondary cleaning to discharge the cleaning liquid.
