Description

Technical Field

[0001] The utility model relates to the technical field of air - energy water heaters, and specifically, to a heat - pipe pressure - bearing anti - scaling air - energy water heater. Background Technique

[0002] As an energy - saving and environment - friendly hot - water supply device, air - energy water heaters have been widely used in modern life. Existing air - energy water heaters mainly absorb heat from the outside air through a refrigerant and transfer it to the heating coil in the condenser, and then conduct the heat to the water to be heated to increase the water temperature. However, there are still some deficiencies in this heat - transfer method.

[0003] On the one hand, the heat - exchange method adopted by traditional air - energy water heaters has relatively low efficiency. There is a certain thermal resistance in the heat - transfer process between the refrigerant and the heating coil, which leads to large heat losses in the energy - transfer process, thus reducing the overall energy - utilization efficiency. On the other hand, a layer of scale is likely to form on the surface of the heating coil after long - term use. The presence of scale will significantly increase the resistance of heat transfer, making it difficult for heat to be effectively transferred to the water. At the same time, it will also exacerbate the corrosion problem of the equipment and shorten the service life of the equipment. In addition, due to the limitation of the heating - coil structure, it is very difficult to effectively remove the formed scale, which will greatly affect the heat - transfer efficiency between the condenser and the water to be heated during the subsequent use of the water heater. No effective solution has been proposed for the problems in the related technology. Content of the Utility Model

[0004] In view of the problems in the related technology, the utility model provides a heat - pipe pressure - bearing anti - scaling air - energy water heater to overcome the above - mentioned technical problems existing in the existing related technology.

[0005] Therefore, the specific technical solution adopted by the utility model is as follows:

[0006] A heat - pipe pressure - bearing anti - scaling air - energy water heater, comprising a condenser. A pressure - bearing water tank is fixedly installed below the condenser. A cold - water pipe is fixedly installed on one side of the pressure - bearing water tank. The bottom of the condenser is fixedly connected with a heat pipe. A cleaning cylinder is fixedly connected to the surface of the heat pipe. A return spring is fixedly connected to the top of the cleaning cylinder. The end of the return spring is fixedly connected with a transmission plate. Cleaning rings are fixedly installed on both sides of the surface of the transmission plate. The heat pipe is slidably connected with the cleaning rings. The transmission plate is matched with the inner wall of the cleaning cylinder. Drainage holes are opened on both sides of the surface of the transmission plate. The end of the cold - water pipe is connected to the cleaning cylinder in a penetrating manner.

[0007] Furthermore, in order to compress and input the heat in the external air into the condenser, a conveying pipeline is fixedly connected to one side of the surface of the condenser. The end of the conveying pipeline is fixedly connected to the outdoor unit of the water heater. An evaporator is fixedly installed inside the outdoor unit of the water heater, and a compressor is fixedly connected to one side of the evaporator.

[0008] Furthermore, in order to discharge and use the hot water in the pressure-bearing water tank, a hot water pipe is fixedly installed on one side of the pressure-bearing water tank.

[0009] Furthermore, in order to enable the cold water pipe to drive the transmission plate to move downward through water pressure when delivering water into the cleaning cylinder, the drainage volume of the cold water pipe is greater than the drainage volume of the drainage holes on both sides of the surface of the transmission plate.

[0010] Furthermore, in order to supply power to each electrical component in the water heater, a power interface is opened on one side of the surface of the condenser.

[0011] Furthermore, in order to control the discharged water of the cold water pipe and the hot water pipe, stop valves are rotatably installed on one side of the surfaces of the cold water pipe and the hot water pipe.

[0012] Furthermore, in order to stably place the pressure-bearing water tank and the condenser, a stabilizing base is fixedly connected to the bottom of the pressure-bearing water tank.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. After injecting the cold water to be heated into the cleaning cylinder through the cold water pipe, the water pressure in the cleaning cylinder makes the transmission plate drive the cleaning ring to move downward on the surface of the heat pipe. When the water pressure in the cleaning cylinder is balanced with the outside, the return spring at the top of the cleaning cylinder drives the transmission plate and the cleaning ring to move upward on the surface of the heat pipe through its own elastic force. Thus, each time the cold water pipe delivers water, the cleaning ring continuously wipes the surface of the heat pipe, effectively preventing the scale in the cylinder from adsorbing on the surface of the heat pipe and affecting the heat transfer efficiency of the condenser.

[0015] 2. Through the heat pipe installed at the end of the condenser, one end of the heat pipe is in contact with the refrigerant, and the other end is in contact with water. Through the relatively high heat conduction efficiency of the heat pipe itself, compared with the heating coil in the traditional condenser, the heat in the refrigerant can be more effectively transferred to the water, greatly improving the heat utilization rate of the refrigerant, and it is more convenient to clean the surface of the heat pipe to prevent the influence of scale.

[0024] According to an embodiment of the present utility model, a heat pipe pressure-bearing scale-preventing air energy water heater is provided.

[0025] Embodiment 1:

[0026] As Figures 1-4As shown in the figure, a heat pipe 4 pressure-bearing scale prevention air energy water heater according to an embodiment of the present invention includes a condenser 1, which is used to condense high-temperature and high-pressure gas into liquid and release heat; a pressure-bearing water tank 2 is fixedly installed below the condenser 1, and a cold water pipe 3 is fixedly installed on one side of the pressure-bearing water tank 2 for injecting cold water into the pressure-bearing water tank 2; the bottom of the condenser 1 is fixedly connected to a heat pipe 4, one end of the heat pipe 4 is in contact with the refrigerant, and the other end is in contact with the water in the pressure-bearing water tank 2 for efficiently transferring heat; a cleaning cylinder 5 with an open bottom is fixedly connected to the surface of the heat pipe 4, a return spring 6 is fixedly connected to the top of the inner wall of the cleaning cylinder 5, the end of the return spring 6 is fixedly connected to a transmission plate 7, and cleaning rings 8 are fixedly installed on both sides of the surface of the transmission plate 7. The heat pipe 4 is slidably connected to the cleaning rings 8, and a carbon fiber composite material is provided on the inner wall of the cleaning rings 8 for wiping and cleaning the surface of the heat pipe 4; the transmission plate 7 is matched with the inner wall of the cleaning cylinder 5, and a pair of drainage holes 9 are opened on both sides of the surface of the transmission plate 7. The end of the cold water pipe 3 is connected to the cleaning cylinder 5 in a penetrating manner.

[0027] As Figures 1-4 shown, a conveying pipeline 10 is fixedly connected to one side of the surface of the condenser 1, the end of the conveying pipeline 10 is fixedly connected to a water heater outdoor unit 11, and an evaporator 12 is fixedly installed inside the water heater outdoor unit 11 for absorbing heat from the surrounding air and evaporating the refrigerant; a compressor 13 is fixedly connected to one side of the evaporator 12 to compress the refrigerant to make it into a high-temperature and high-pressure gas and send it to the condenser 1 through a conveying pipe; a hot water pipe 14 is fixedly installed on one side of the pressure-bearing water tank 2 for discharging and using the hot water in the pressure-bearing water tank 2; the drainage volume of the cold water pipe 3 is much larger than the sum of the drainage volumes of the two drainage holes 9 on the surface of the transmission plate 7. When the cold water pipe 3 conveys water into the cleaning cylinder 5, a large water pressure is formed in the cleaning cylinder 5 to push the transmission plate 7 to move downward; a power supply interface 15 is opened on one side of the surface of the condenser 1 for providing power to each electrical component in the water heater; stop valves 16 are rotatably installed on one side of the surfaces of the cold water pipe 3 and the hot water pipe 14 for controlling the discharge of water from the cold water pipe 3 and the hot water pipe 14; a stabilizing base 17 is fixedly connected to the bottom of the pressure-bearing water tank 2 for stably placing the pressure-bearing water tank 2 and the condenser 1.

[0028] In order to facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0029] In summary, by means of the above technical solution of the present utility model, during actual use, heat is absorbed from the surrounding air by the evaporator 12, and after the refrigerant evaporates, the compressor 13 compresses the refrigerant to make it into a high-temperature and high-pressure gas, which is sent into the condenser 1 through the conveying pipeline 10. The condenser 1 condenses the high-temperature and high-pressure refrigerant gas into a liquid and releases heat to be transferred to the heat pipe 4, and the cold water in the pressure-bearing water tank 2 is heated through the transfer of the heat pipe 4; when the pressure-bearing water tank 2 is filled with water through the cold water pipe 3, the injected water first enters the cleaning cylinder 5. Since the drainage capacity of the drainage holes 9 on the transmission plate 7 is much smaller than the water injection volume of the cold water pipe 3, a relatively large water pressure is formed in the cleaning cylinder 5, causing the transmission plate 7 to pull the return spring 6 to elongate and drive the cleaning ring 8 to move downward on the surface of the heat pipe 4. When the water pressure in the cleaning cylinder 5 gradually balances with the outside, the return spring 6 at the top of the cleaning cylinder 5 drives the transmission plate 7 and the cleaning ring 8 to move upward on the surface of the heat pipe 4 through its own elastic force. Thus, each time the cold water pipe 3 conveys water, the cleaning ring 8 continuously wipes the surface of the heat pipe 4 to prevent scale from adsorbing on the surface of the heat pipe 4 and affecting the heat transfer efficiency of the heat pipe 4.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
