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 energy water heater is a new type of water heater, which has many advantages such as high efficiency, energy saving and environmental protection. The working principle of air energy water heater is to heat water by absorbing heat energy from the air. It is mainly composed of compressor, condenser, expansion valve and evaporator. The compressor compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas, and then transfers the heat to the water in the water tank through the condenser to increase the temperature of the water. After cooling in the condenser, the refrigerant becomes a high-pressure liquid, and then reduces the pressure and temperature through the expansion valve to become a low-temperature and low-pressure liquid, and finally enters the evaporator to absorb the heat energy in the air to complete a cycle. Compared with traditional electric water heaters and gas water heaters, air energy water heaters have significant advantages. First, it is very energy-saving. Because it mainly obtains heat from the air, instead of directly consuming electricity to heat water like electric water heaters, its power consumption is only about a quarter of that of electric water heaters. For example, a family may need to pay 100 yuan for electricity per month using an electric water heater, while using an air energy water heater may only cost about 25 yuan. Secondly, air energy water heaters are environmentally friendly and pollution-free. It does not produce waste gas and waste residue, and is environmentally friendly. Moreover, it is highly safe. There is no risk of gas leakage and electric shock, and it is more assured to use. The water tank capacity of air-energy water heaters usually has a variety of options to meet the needs of different families. Generally speaking, the larger the family population, the larger the required water tank capacity. In addition, the service life of air-energy water heaters is longer, up to 10-15 years. In terms of installation, it requires a certain amount of space and is usually installed outdoors or on a balcony.

[0003] Air-energy water heater is an energy-saving household appliance, which mainly uses a compressor, an expansion valve, a water tank, an evaporator and the heat in the air to heat the water. The heat exchange tube is directly introduced into the water tank, so that the water in the water tank does not come into contact with electricity, which improves the safety performance. However, the existing air-energy water heater has the following problems when in use: The heat exchange tubes of air-energy water heaters are divided into outer disc type and inner disc type. Among them, the inner disc heat exchange tube can directly contact with water in the water tank, which can improve the heat exchange efficiency and is widely used. However, due to the water quality problem in the water tank, scale will form on the surface of the inner disc heat exchange tube during long-term use, affecting the thermal conductivity. The existing air-energy water heater is not convenient to clean the scale on the inner disc heat exchange tube in time, which affects the heating effect of the inner disc heat exchange tube.

[0004] Therefore, a scale-proof air-energy water heater is needed to solve the problem in the prior art that it is inconvenient to clean the scale on the inner disc heat exchange tube in time, thereby affecting the heating effect of the inner disc heat exchange tube. Summary of the invention

[0023] A specific embodiment of the present invention, as Figure 1-Figure 11 As shown, an anti-scaling air-energy water heater is disclosed, including a water tank 100, a fixed ring 101 is fixed on one side of the water tank 100, a plurality of inner plate heat exchange tubes 102 distributed in a circle are fixed on one side of the fixed ring 101, a movable ring 200 is arranged in the water tank 100, a plurality of sleeve holes 201 distributed in a circle and matched with the inner plate heat exchange tubes 102 are opened on one side of the movable ring 200, a plurality of scrapers 203 distributed in a circle and corresponding to the sleeve holes 201 are arranged on one side of the movable ring 200, three connecting rods 202 distributed in a circle are fixed on the edge of one side of the scraper 203, one end of the connecting rod 202 is fixed to one side of the movable ring 200, and a pushing assembly is arranged on the other side of the water tank 100.

[0024] As a further solution of the present invention, the pushing assembly includes a fixed frame 301, which is fixed to the other side of the water tank 100. An L-shaped tube 300 is fixed to the inner wall of the fixed frame 301. A first piston 303 is movably engaged at a horizontal position inside the L-shaped tube 300. A moving rod 302 is fixed at one end of the first piston 303. The moving rod 302 can move through the L-shaped tube 300. A second piston 400 is movably engaged at a vertical position inside the L-shaped tube 300. A counterweight column 401 is fixed to the bottom surface of the second piston 400, and a float bucket 402 is fixed to the bottom surface of the counterweight column 401.

[0025] By setting the pushing assembly, when water is injected into the water tank 100 , the float 402 will slowly rise, thereby compressing the air inside the L-shaped tube 300 , and the air pushes the first piston 303 to move, and the movement of the first piston 303 pushes the fixing plate 304 to move, so that the first magnet 307 is close to the second magnet 501 .

[0026] As a further solution of the present invention, a fixing plate 304 is fixed to one end of the moving rod 302 , and a plurality of first magnets 307 distributed in a circumference are fixed to one side of the fixing plate 304 .

[0027] The first magnet 307 can be fixed by the setting of the fixing plate 304 , and the first magnet 307 can cooperate with the second magnet 501 by the setting of the first magnet 307 .

[0028] The first magnet 307 and the second magnet 501 are arranged close to each other on one side and are of the same polarity.

[0029] As a further solution of the present invention, a central column 305 is fixed to the middle of one side of the fixing plate 304 , and a plurality of first baffles 306 distributed in a circumference are fixed to the outer side wall of the central column 305 .

[0030] The first baffle 306 is provided to separate adjacent first magnets 307 , thereby preventing adjacent first magnets 307 from influencing each other.

[0031] As a further solution of the present invention, a mounting ring 500 is fixed to the inner wall of the movable ring 200, a plurality of circumferentially distributed second magnets 501 are fixed to one side of the mounting ring 500, and a plurality of circumferentially distributed second baffles 502 are fixed to one side of the mounting ring 500.

[0032] The second magnet 501 is provided so that the second magnet 501 can cooperate with the first magnet 307 , and the second baffle 502 is provided so that adjacent second magnets 501 can be separated to avoid mutual influence between adjacent second magnets 501 .

[0033] This solution has the following working process: open the valve of the tap water pipe connected to the water inlet pipe 800, and the tap water enters the water tank 100 through the water inlet pipe 800. The water in the water tank 100 rises slowly, causing the float 402 to rise slowly. The rise of the float 402 drives the counterweight column 401 to rise. The rise of the counterweight column 401 drives the second piston 400 to rise. The rise of the second piston 400 drives the air in the L-shaped tube 300, and then drives the first piston 303. The movement of the first piston 303 drives the first magnet 307 to move. Since there is a repulsive force between the first magnet 307 and the second magnet 501, the second magnet 501 is pushed by the first magnet 307. The movement of 501 drives the moving ring 200 to move, so that the scraper 203 moves. The scraper 203 scrapes and cleans the outer wall of the inner plate heat exchange tube 102, and scrapes the dirt on the outer wall of the inner plate heat exchange tube 102. At this time, the spring 505 is stretched, and the inner plate heat exchange tube 102 heats the water in the water tank 100. When hot water is used, the valve of the pipe connected to the drain pipe 801 is opened, and the hot water is discharged from the drain pipe 801 to the corresponding position. When the water in the water tank 100 is slowly discharged, the float 402 slowly descends, the first piston 303 slowly resets, and the spring 505 slowly resets until the first magnet 307 and the second magnet 501 return to their initial positions.

[0034] When cleaning the dirt on the side where the first magnet 307 and the second magnet 501 are close to each other, the two electric push rods 701 are started at the same time, and the electric push rods 701 drive the housing 600 to move downward, so that the friction plates 604 on both sides contact the first magnet 307 and the second magnet 501 respectively. At this time, the incomplete rack 605 is manually pulled up and down to rotate the gear 602, and then the friction plates 604 on both sides rotate to clean the side where the first magnet 307 and the second magnet 501 are close to each other.

[0035] According to the above working process, it can be known that: by setting the float barrel 402, when the water in the water tank 100 slowly increases, the air in the L-shaped tube 300 can be pushed, thereby pushing the first piston 303 to move, so that the first magnet 307 is close to the second magnet 501, and the scraper 203 is set, so that the dirt on the outer wall of the inner disk heating tube can be scraped and cleaned, and by the spring 505, after the water in the water tank 100 is discharged, the movable ring 200 can be reset, so that the dirt on the outer wall of the inner disk heat exchange tube 102 can be easily cleaned to avoid affecting the heating effect of the inner disk heat exchange tube 102.

[0036] By setting the incomplete rack 605 and the gear 602, the friction plate 604 can be rotated, and the friction plate 604 can be used to clean the dirt on the side where the first magnet 307 and the second magnet 501 are close to each other, thereby preventing the dirt adsorbed on the side where the first magnet 307 and the second magnet 501 are close to each other from affecting the magnetic force of the first magnet 307 and the second magnet 501.

[0037] As a further solution of the present invention, a retaining ring 403 is fixed to the bottom of the inner wall of the L-shaped tube 300 at a vertical position.

[0038] The stop ring 403 is provided to prevent the second piston 400 from moving out of the L-shaped tube 300 .

[0039] As a further solution of the present invention, three limiting columns 503 distributed in a circle are fixed to one side of the fixing ring 101, a fixing rod 504 is fixed to one end of the limiting column 503, one end of the fixing rod 504 is fixed to the inner wall of the water tank 100, a spring 505 is provided on one side of the outer wall of the limiting column 503, one end of the spring 505 is fixed to one side of the fixing rod 504, and the other end of the spring 505 is fixed to one side of the movable ring 200.

[0040] By setting the limiting column 503, the position of the movable ring 200 can be movably limited, and by setting the spring 505, the spring 505 can be stretched when the movable ring 200 moves, so that after the water in the water tank 100 is discharged, the spring 505 can pull the movable ring 200 to return to its original position.

[0041] As a further solution of the present invention, the top surface of the inner wall of the water tank 100 is movably engaged with the shell 600, and the bottom of the inner wall of the shell 600 is movably connected with a rotating shaft 601 close to one side, and a gear 602 is fixed to the outer wall of the rotating shaft 601, and mounting plates 603 are respectively fixed at both ends of the rotating shaft 601, and a friction plate 604 is fixed to one side of the mounting plate 603. An incomplete rack 605 is movably engaged with the top surface of the inner wall of the shell 600, and the incomplete rack 605 is meshed with the gear 602. A limiting hole 606 is provided on the bottom surface of the incomplete rack 605, and a positioning column 607 is fixed to the bottom surface of the inner wall of the shell 600, and the positioning column 607 is engaged in the limiting hole 606.

[0042] By setting the incomplete rack 605 and the gear 602, the rotating shaft 601 can rotate, and by setting the friction plate 604, the side where the first magnet 307 and the second magnet 501 are close to each other can be scrubbed separately, thereby cleaning the dirt on the side where the first magnet 307 and the second magnet 501 are close to each other, avoiding affecting the magnetic force of the first magnet 307 and the second magnet 501.

[0043] As a further solution of the present invention, positioning plates 700 are fixed to the tops of the two opposite side surfaces of the outer wall of the shell 600, and two electric push rods 701 are fixed to the top surface of the water tank 100. The output ends of the electric push rods 701 are fixed to the bottom surface of the positioning plates 700.

[0044] The housing 600 can be moved by the electric push rod 701 , so that the friction plate 604 can be moved between the first magnet 307 and the second magnet 501 .

[0045] As a further solution of the present invention, a water inlet pipe 800 is connected through one side of the top surface of the water tank 100, and a drain pipe 801 is connected through one side surface of the water tank 100.

[0046] Through the provided water inlet pipe 800 , tap water can enter the water tank 100 through the water inlet pipe 800 , and through the provided drain pipe 801 , the heated hot water can be transported to a corresponding location through the drain pipe 801 .

[0047] In summary: open the valve of the water pipe connected to the water inlet pipe 800, and the tap water enters the water tank 100 through the water inlet pipe 800. The water in the water tank 100 rises slowly, causing the float 402 to rise slowly. The rise of the float 402 drives the counterweight column 401 to rise. The rise of the counterweight column 401 drives the second piston 400 to rise. The rise of the second piston 400 drives the air in the L-shaped tube 300, and then drives the first piston 303. The movement of the first piston 303 drives the movement of the first magnet 307. Since there is a repulsive force between the first magnet 307 and the second magnet 501, the second magnet 501 is pushed by the first magnet 307, and the second magnet 501 moves. The movable ring 200 is driven to move, so that the scraper 203 moves, and the scraper 203 scrapes and cleans the outer wall of the inner disk heat exchange tube 102, and scrapes off the dirt on the outer wall of the inner disk heat exchange tube 102. At this time, the spring 505 is stretched, and the inner disk heat exchange tube 102 heats the water in the water tank 100. When hot water is used, the valve of the pipe connected to the drain pipe 801 is opened, and the hot water is discharged from the drain pipe 801 to the corresponding position. When the water in the water tank 100 is slowly discharged, the float 402 slowly descends, the first piston 303 slowly resets, and the spring 505 slowly resets until the first magnet 307 and the second magnet 501 return to their initial positions.

[0048] When cleaning the dirt on the side where the first magnet 307 and the second magnet 501 are close to each other, the two electric push rods 701 are started at the same time, and the electric push rods 701 drive the housing 600 to move downward, so that the friction plates 604 on both sides contact the first magnet 307 and the second magnet 501 respectively. At this time, the incomplete rack 605 is manually pulled up and down to rotate the gear 602, and then the friction plates 604 on both sides rotate to clean the side where the first magnet 307 and the second magnet 501 are close to each other.

[0049] The inner plate heat exchange tube 102 and the electric push rod 701 can be purchased on the market. They are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
