[0038] The embodiment of the present invention provides an air energy heat pump water heater, which solves the problem that the water heater itself increases scale and air circulation becomes low due to a long time, resulting in reduced heat exchange, thereby improving the heat exchange efficiency of the air energy heat pump water heater and meeting people's daily needs.

[0039] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems. The overall idea is as follows: during the use of the air-energy heat pump water heater, the filter on the bellows is first cleaned to improve the air circulation, thereby accelerating the heat absorption and evaporation of the refrigerant. The vaporized refrigerant heats the water through the heat exchange tube. At the same time, the surface of the heat exchange tube is cleaned to avoid scale adhesion and thus improve the heat exchange rate. Secondly, the water in the water tank is stirred and shaken to avoid the temperature of the water close to the heat exchange tube being higher than the temperature of the water far away from the heat exchange tube, so that the water in different areas can be in contact with the heat exchange tube circulation, thereby further accelerating the heat exchange rate.

[0040] See also Figures 1 to 6 The present invention provides an air energy heat pump water heater, and the technical solution is as follows:

[0041] An air energy heat pump water heater, comprising:

[0042] A water heater housing 1, which can be used to provide support when the water heater is installed;

[0048] A debris removal mechanism 5 for improving heat exchange efficiency is provided on the right side of the water heater housing 1 .

[0049] The compressor 3 draws low-temperature and low-pressure gaseous refrigerant from the evaporator 2 through the heat exchange tube 6 and compresses it into high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant enters the water tank 30 through the heat exchange tube 6 to exchange heat with water, releasing heat to increase the water temperature. The high-temperature and high-pressure gaseous refrigerant becomes liquid refrigerant after releasing heat energy. The liquid refrigerant enters the evaporator 2 through the heat exchange tube 6 to absorb heat from the outdoor air and evaporates again into low-temperature and low-pressure gaseous refrigerant. The above process is repeated to produce hot water. The water tank 5 can store water.

[0050] As an embodiment of the present invention, refer to Figure 1 and Figure 2 A protective cover 7 is fixedly connected to the right top wall of the water heater housing 1 , a sound insulation cotton 8 is fixedly installed on the inner wall of the protective cover 7 , and a motor 9 is fixedly connected to the top inner wall of the protective cover 7 .

[0051] The motor 9 can be used to drive the impurity removal mechanism 5. The operation of the impurity removal mechanism 5 can improve the heat exchange efficiency. At the same time, the sound insulation cotton 8 can effectively prevent the motor 9 from making excessive noise and affecting people's normal life.

[0052] As an embodiment of the present invention, refer to Figure 2 and Figure 3 The output shaft of the motor 9 is fixedly connected to a reciprocating screw 10, which extends all the way to the bottom inner wall of the water tank 30 and is rotatably connected to the bottom inner wall of the water tank 30. The outer side of the reciprocating screw 10 is spirally driven with a connecting block 11, and the left side of the connecting block 11 is fixedly connected to a ring brush 12, and the bristles of the ring brush 12 are in contact with the surface of the heat exchange tube 6.

[0053] The motor 9 drives the reciprocating screw 10 to rotate, the reciprocating screw 10 drives the connecting block 11 to move up and down, the connecting block 11 drives the annular brush 12 to move up and down, and the annular brush 12 moves up and down to effectively clean the scale on the surface of the heat exchange tube 6 inside the water tank 30, thereby improving the heat exchange efficiency and accelerating the rise of water temperature.

[0054] As an embodiment of the present invention, refer to Figure 2 and Figure 4 A ring gear 13 is rotatably connected to the inner wall of the water tank 30, a gear 14 is meshedly connected to the right inner wall of the ring gear 13, the inner wall of the gear 14 is fixedly connected to the reciprocating screw 10, and a shift rod 16 is symmetrically fixedly connected to the top side wall of the ring gear 13, and a plurality of shift plates 17 are fixedly connected to the inner sides of the two shift rods 16.

[0055] The gear 14 drives the ring gear 13 to rotate, the ring gear 13 drives the lever 16 to rotate, the lever 16 drives the paddle 17 to rotate, and the rotation of the paddle 17 can effectively stir the water in the water tank 30, thereby improving the fluidity of the water and accelerating the increase of the water temperature.

[0056] As an embodiment of the present invention, refer to Figure 2 and Figure 5 Tuning forks 18 are fixedly connected to the outer walls of the plurality of paddle plates 17 , and the plurality of tuning forks 18 penetrate the paddle rod 16 . A grinding plate 19 is fixedly installed on the inner wall of the water tank 30 , and the inner wall of the grinding plate 19 contacts the plurality of tuning forks 18 .

[0057] The paddle 17 drives the tuning fork 18 to rotate, and friction occurs between the tuning fork 18 and the grinding plate 19. The tuning fork 18 generates high-frequency vibration through friction, and the tuning fork 18 drives the paddle 17 to vibrate. The rotation of the paddle 17 increases the water flowability and further increases the water flowability through vibration, thereby further accelerating the rise in water temperature.

[0058] As an embodiment of the present invention, refer to Figure 2 and Figure 5 , the dial plate 17 is made of metal.

[0059] The metal-made plate 17 can effectively reduce the corrosion rate and increase the service life.

[0060] As an embodiment of the present invention, refer to Figure 2 and Figure 6A first bevel gear 20 is fixedly sleeved on the outer side of the reciprocating screw rod 10, a second bevel gear 21 is meshedly connected to the left side of the first bevel gear 20, a cross bar 22 is fixedly connected to the left side of the second bevel gear 21, a circular plate 23 is fixedly connected to the left end of the cross bar 22, a short bolt 24 is fixedly connected to the upper left side wall of the circular plate 23, a brush rod 25 is rotatably connected to the left side wall of the water heater housing 1, a slide groove 26 is opened on the left side of the brush rod 25, the short bolt 24 contacts the inner wall of the slide groove 26, and the brush rod 25 contacts the bellows 4.

[0061] The reciprocating screw 10 drives the first bevel gear 20 to rotate, the first bevel gear 20 drives the second bevel gear 21 to rotate, the second bevel gear 21 drives the cross bar 22 to rotate, the cross bar 22 drives the circular plate 23 to rotate, the circular plate 23 drives the short bolt 24 to rotate, and the short bolt 24 will slide along the inner wall of the slide groove 26 while rotating in a circle. At the same time, the short bolt 24 is in contact with the inner wall of the slide groove 26, so the short bolt 24 will not drive the slide groove 26 to rotate, which in turn causes the slide groove 26 to drive the brush rod 25 to swing at the rotating connection between the brush rod 25 and the water heater housing 1. The swing of the brush rod 25 can clean the filter on the bellows 4 to avoid the long-term use of the filter resulting in a decrease in air circulation. The decrease in air circulation will cause the speed of liquid refrigerant absorbing heat and gasifying to decrease. On the contrary, the overall heat exchange efficiency can be effectively improved by cleaning.

[0062] As an embodiment of the present invention, refer to Figure 2 , the number of teeth of the first bevel gear 20 is five times the number of teeth of the second bevel gear 21.

[0063] The number of teeth of the second bevel gear 21 is less than that of the first bevel gear 20 , so that when the first bevel gear 20 rotates, the second bevel gear 21 can rotate faster, thereby significantly improving the cleaning speed of the filter screen by the brush rod 25 .

[0064] As an embodiment of the present invention, refer to Figure 2 A liquid inlet pipe 27 is fixedly connected to the upper right side of the water tank 30, and a liquid outlet pipe 28 is fixedly connected to the lower right side of the water tank 30. Valves 29 are fixedly installed on the outer side walls of the liquid inlet pipe 27 and the liquid outlet pipe 28.

[0065] By installing valves 29 on the liquid inlet pipe 27 and the liquid outlet pipe 28, it is easier to control the water in the water tank 30. When drainage is required, the valve 29 on the liquid outlet pipe 28 can be opened, and when water injection is required, the valve 29 on the liquid inlet pipe 27 can be opened.

[0066] As an embodiment of the present invention, refer to Figure 2 The outer side of the cross bar 22 is fixedly sleeved with the inner ring of the bearing 15 , and the outer side of the bearing 15 is fixedly connected to the top inner wall of the water heater housing 1 .

[0067] The bearing 15 can provide a stable supporting force for the cross bar 22 when it rotates, thereby preventing the cross bar 22 from deviating during rotation and affecting normal use.

[0068] Working principle: The low-temperature and low-pressure gaseous refrigerant is sucked in from the evaporator 2 through the heat exchange tube 6 by the compressor 3 and compressed into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant enters the water tank 30 through the heat exchange tube 6 to exchange heat with water, releasing heat to increase the water temperature. The high-temperature and high-pressure gaseous refrigerant becomes liquid refrigerant after releasing heat energy. The liquid refrigerant enters the evaporator 2 through the heat exchange tube 6 to absorb heat from the outdoor air and evaporates again into a low-temperature and low-pressure gaseous refrigerant. The above process is repeated to produce hot water. The water tank 5 can store water. The motor 9 can be used to drive the impurity removal mechanism 5. The heat exchange efficiency is improved by the operation of the impurity removal mechanism 5. At the same time, the sound insulation cotton 8 can effectively prevent the motor 9 from making excessive noise and affecting people's normal life. The motor 9 drives the The multi-thread rod 10 rotates, and the reciprocating thread rod 10 drives the connecting block 11 to move up and down, and the connecting block 11 drives the annular brush 12 to move up and down, and the annular brush 12 moves up and down to effectively clean the scale on the surface of the heat exchange tube 6 inside the water tank 30, thereby improving the heat exchange efficiency and accelerating the rise of water temperature. The gear 14 drives the ring gear 13 to rotate, and the ring gear 13 drives the lever 16 to rotate, and the lever 16 drives the paddle 17 to rotate. The rotation of the paddle 17 can effectively stir the water in the water tank 30, thereby improving the fluidity of the water and accelerating the rise of water temperature. The paddle 17 drives the tuning fork 18 to rotate, and the tuning fork 18 rotates and rubs against the grinding plate 19, and the tuning fork 18 generates high-frequency vibration through friction, and the tuning fork 18 drives the paddle 17 to vibrate. The rotation of the paddle 17 increases the water fluidity while The vibration further increases the fluidity of water, thereby further accelerating the rise in water temperature. The metal paddle 17 can effectively reduce the corrosion rate and increase the service life. The reciprocating screw 10 drives the first bevel gear 20 to rotate, the first bevel gear 20 drives the second bevel gear 21 to rotate, the second bevel gear 21 drives the cross bar 22 to rotate, the cross bar 22 drives the circular plate 23 to rotate, the circular plate 23 drives the short bolt 24 to rotate, and the short bolt 24 will slide along the inner wall of the slide groove 26 while rotating in a circle. At the same time, the short bolt 24 is in contact with the inner wall of the slide groove 26, so the short bolt 24 will not drive the slide groove 26 to rotate, thereby causing the slide groove 26 to drive the brush rod 25 to swing at the rotating connection between the brush rod 25 and the water heater housing 1, and the swing of the brush rod 25 can clean the filter on the bellows 4. The filter screen is cleaned to avoid long-term use of the filter screen, which may lead to reduced air circulation. Reduced air circulation will lead to a decrease in the speed of liquid refrigerant absorbing heat and vaporizing. On the contrary, cleaning can effectively improve the overall heat exchange efficiency. The number of teeth of the second bevel gear 21 is less than that of the first bevel gear 20. When the first bevel gear 20 rotates, the second bevel gear 21 can rotate faster, thereby significantly improving the cleaning speed of the filter screen by the brush rod 25. By installing valves 29 on the liquid inlet pipe 27 and the liquid outlet pipe 28, it is easier to control the water in the water tank 30. When drainage is required, the valve 29 on the liquid outlet pipe 28 can be opened. When water injection is required, the valve 29 on the liquid inlet pipe 27 can be opened. The bearing 15 can provide a stable supporting force for the cross bar 22 when it rotates.Avoid the cross bar 22 from deviating during rotation, which may affect normal use.
