Description

Technical Field

[0001] The invention belongs to the technical field of water heaters, and in particular relates to an anti-scaling air energy water heater. Background Art

[0002] Air source water heater, also known as air source heat pump water heater, is an energy-efficient device that uses heat pump technology to absorb heat from the air to heat water. Air source water heater works on the "reverse Carnot" principle, extracting heat from the outdoor air and transferring it to the water in the indoor water tank, thereby heating domestic water.

[0003] The air-energy water heater using a built-in condenser has a compact structure and can directly contact the water in the water tank. The heat transfer is direct, which reduces heat loss. However, the water quality in the area used is relatively hard, and scale is easily formed on the surface of the condenser, affecting the heat exchange efficiency, so it needs to be descaled. Summary of the invention

[0004] The present invention aims to solve the problem that scale will be generated when the air energy water heater is used in a hard water area in the prior art, and proposes the following technical solution:

[0005] An anti-scaling air-energy water heater, comprising: a water storage tank and a descaling assembly, wherein a water inlet pipe and a water outlet pipe are respectively arranged on both sides of the water storage tank, the descaling assembly comprises a rotating shaft and a power member, a mounting frame with a cleaning brush is fixedly connected to the middle of the rotating shaft, and one side of the cleaning brush is in contact with the inner surface of the water storage tank and the surface of a condenser coiled in the water storage tank;

[0006] The cold water entering through the water inlet pipe impacts the power part, causing it to rotate the rotating shaft, and the cleaning brush then cleans the generated scale.

[0007] As a preferred embodiment of the above technical solution, the power part includes a mounting disk, a rotating block is rotatably inserted inside the mounting disk, and a plurality of impact plates are circumferentially arranged on the outer side of the rotating block. The cold water entering through the water inlet pipe impacts the impact plate to push the rotating block to move, and the plurality of impact plates enter the impact position in turn to rotate the rotating block to provide power for the rotating shaft.

[0008] As a preferred embodiment of the above technical solution, a water inlet and a water outlet are provided on the surface of the mounting plate, and a surface on one side of the water outlet is tangent to the circular inner wall surface of the mounting plate.

[0009] As a preferred embodiment of the above technical solution, the descaling assembly also includes a lifting member, which includes a lifting block and a plug-in block. The lifting block is fixedly connected to the mounting plate, a guide wheel is provided on the top of the lifting block, the guide wheel shaft is fixedly connected to the rotating shaft, one end of the plug-in block is fixedly connected to the rotating shaft, and the other end of the plug-in block is movably plugged into the rotating block.

[0010] As a preferred embodiment of the above technical solution, the surface of the lifting block is arranged in an irregular wavy shape, and the guide wheel matches its surface.

[0011] As a preferred embodiment of the above technical solution, a return spring is arranged between the plug-in block and the rotating block, and two ends of the return spring are fixedly connected to the plug-in block and the rotating block respectively.

[0012] As a preferred embodiment of the above technical solution, the middle part of the rotating shaft and the mounting frame are filled with buoyancy materials. When the water level inside the water tank is higher than the middle part of the water tank, the rotating shaft and the mounting frame float up and drive the guide wheel to leave the position of the lifting block to make the lifting part inoperable.

[0013] As a preferred embodiment of the above technical solution, it also includes: a water heater shell and a control mechanism, and a heat-insulating material is arranged between the water heater shell and the water storage tank. The water heater shell, the control mechanism and the water storage tank constitute a "water heater internal unit".

[0014] The beneficial effects of the present invention are:

[0015] 1. Use the incoming water flow to provide power for the power parts to rotate the rotating shaft, and the cleaning brush will rotate to clean the scale attached to the inner wall surface of the water storage tank to prevent the generated scale from affecting the heating work of the air energy water heater;

[0016] 2. Under the protection of the mounting plate, the rotating block drives multiple impact plates to rotate inside the mounting plate, which can reduce the influence of external water flow, water pressure and other factors on the power parts, making the driving force of the power parts on the rotating shaft more stable;

[0017] 3. The lifting piece can be moved back and forth in the vertical direction when the rotating shaft rotates, so that the cleaning brush can better clean the scale. When the water level inside the water tank is higher than the middle of the water tank, the buoyancy received by the rotating shaft and the mounting frame is greater than the tension of the return spring, and the guide wheel leaves the position of the lifting block to disable the lifting piece, thereby reducing the wear of the lifting piece. At the same time, due to the increase in resistance encountered by the cleaning brush and the rotating shaft during rotation, it is converted from a cleaning state to a stirring state, thereby accelerating the mixing speed of the water flow inside the water tank.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the specification.

[0025] Example

[0026] Figure 1-Figure 5 In the invention, an anti-scaling air energy water heater comprises: a water storage tank 10 and a descaling assembly, wherein a water inlet pipe 11 and a water outlet pipe 12 are respectively arranged on both sides of the water storage tank 10, and the descaling assembly comprises a rotating shaft 20 and a power member 50, and a mounting frame 30 with a cleaning brush 40 is fixedly connected to the middle of the rotating shaft 20, and one side of the cleaning brush 40 is in contact with the inner surface of the water storage tank 10 and the surface of the condenser coiled in the water storage tank 10;

[0027] The cold water entering the water inlet pipe 11 impacts the power member 50 to drive the rotating shaft 20 to rotate, and the cleaning brush 40 cleans the generated scale.

[0028] Cold water enters the water tank 10 from the water inlet pipe 11, and the water flows through the impact power member 50 to drive the rotating shaft 20 to rotate, and the mounting frame 30 rotates accordingly so that the cleaning brush 40 cleans the scale on the inner wall surface of the water tank 10. The cold water is heated by the condenser and stored in the water tank 10, and the heated hot water flows out from the water outlet pipe 12 for use.

[0029] The incoming water flow is used to provide power to the power member 50 to rotate the rotating shaft 20, and the cleaning brush 40 rotates accordingly to clean the scale attached to the inner wall surface of the water storage tank 10 to prevent the generated scale from affecting the heating work of the air-energy water heater.

[0030] Figure 2-Figure 5 In the figure, the power part 50 includes a mounting disk 51, a rotating block 52 is rotatably inserted inside the mounting disk 51, and a plurality of impact plates 53 are circumferentially arranged on the outer side of the rotating block 52. The cold water entering the water inlet pipe 11 impacts the impact plate 53 to push the rotating block 52 to move. The plurality of impact plates 53 enter the impact position in turn to rotate the rotating block 52 to provide power for the rotating shaft 20.

[0031] A water inlet and a water outlet are formed on the surface of the installation plate 51 , and a surface on one side of the water outlet is tangent to the circular inner wall surface of the installation plate 51 .

[0032] After the water flows out from the water inlet pipe 11, it impacts the impact plate 53 to push the rotating block 52. Multiple impact plates 53 enter the impact position in turn to rotate the rotating block 52, and the rotating shaft 20 rotates accordingly. The water flows in from the water inlet and is discharged from the water outlet position as the impact plate 53 rotates, avoiding the return water flow from affecting the incoming water flow.

[0033] Under the protection of the mounting plate 51 , the rotating block 52 drives the multiple impact plates 53 to rotate inside the mounting plate 51 , which can reduce the impact of external water flow, water pressure and other factors on the power component 50 , making the driving force of the power component 50 on the rotating shaft 20 more stable.

[0034] Figure 3-Figure 4 In the figure, the descaling assembly also includes a lifting member 60, and the lifting member 60 includes a lifting block 61 and a plug-in block 62. The lifting block 61 is fixedly connected to the mounting plate 51, and a guide wheel 63 is provided on the top of the lifting block 61. The rotating shaft of the guide wheel 63 is fixedly connected to the rotating shaft 20, one end of the plug-in block 62 is fixedly connected to the rotating shaft 20, and the other end of the plug-in block 62 is movably plugged into the rotating block 52.

[0035] The surface of the lifting block 61 is arranged in an irregular wave shape, and the guide wheel 63 matches its surface.

[0036] A return spring 64 is disposed between the plug-in block 62 and the rotating block 52 , and two ends of the return spring 64 are fixedly connected to the plug-in block 62 and the rotating block 52 , respectively.

[0037] When the rotating shaft 20 rotates, the guide wheel 63 moves and rotates on the surface of the lifting block 61. Since the surface of the lifting block 61 is irregularly wavy, the rotating shaft 20 drives the mounting frame 30 and the cleaning brush 40 to move back and forth in the vertical direction, and the plug-in block 62 moves accordingly and is reset by the return spring 64.

[0038] The lifting member 60 can reciprocate the rotating shaft 20 in the vertical direction when the rotating shaft 20 rotates, so that the cleaning brush 40 has a better cleaning effect on scale.

[0039] Figure 2 In the embodiment, the middle parts of the rotating shaft 20 and the mounting frame 30 are filled with buoyancy materials. When the water level inside the water tank 10 is higher than the middle part of the water tank 10, the rotating shaft 20 and the mounting frame 30 float up and drive the guide wheel 63 to leave the position of the lifting block 61, making the lifting member 60 inoperable.

[0040] When the water level inside the water tank 10 is higher than the middle of the water tank 10, the buoyancy received by the rotating shaft 20 and the mounting frame 30 is greater than the tension of the return spring 64, and the guide wheel 63 leaves the position of the lifting block 61 to render the lifting member 60 inoperable, thereby reducing the wear of the lifting member 60. At the same time, due to the increase in resistance encountered by the cleaning brush 40 and the rotating shaft 20 during rotation, it is converted from a cleaning state to a stirring state, thereby accelerating the mixing speed of the water flow inside the water tank 10.

[0041] It also includes: a water heater shell and a control mechanism, and a heat-insulating material is arranged between the water heater shell and the water storage tank 10. The water heater shell, the control mechanism and the water storage tank 10 constitute a "water heater internal unit".

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
