[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0023] First embodiment:

[0024] like Figures 1-3 As shown, this utility model provides a pipe filtration device for a hot water unit, including a water storage tank 1 for storing water. The water storage tank 1 is equipped with a water inlet pipe 11 for inlet water and a water outlet pipe 12 for outlet water. The water outlet pipe 12 is connected to a water flow control component 2 for controlling the water flow circulation direction. The water flow control component 2 is connected to a heat exchanger 13 for heat exchange. The heat exchanger 13 is equipped with a water outlet end 14, and the other end of the water outlet end 14 is connected to a filter component 3 for filtering the pipe. The top of the filter assembly 3 is provided with a drain pipe 15 for drainage, and the other end of the drain pipe 15 is provided with a connecting pipe 16 for connection. The filter assembly 3 includes a filter tank 31 for installation and a connecting pipe 32 for connection. The connecting pipe 32 is connected to the water outlet 14. The inner cavity of the filter tank 31 is provided with a filter screen 33 for filtration. The filter tank 31 is also provided with a discharge pipe 34 for connecting the drain pipe 15. One end of the discharge pipe 34 passes through the filter tank 31 and the filter screen 33 and is located inside the filter screen 33. In actual use, the staff can first fill the water tank 1 with water through the water filling pipe 11. Then, the staff can control the water flow control component 2 to make the water in the water filling pipe 11 flow into the heat exchanger 13 to achieve the effect of heat exchange. After heat exchange, the water will flow through the outlet 14 to the filter tank 31, and the filter screen 33 installed in the filter tank 31 will achieve the effect of filtration. Finally, it will be discharged through the discharge pipe 34 to the drain pipe 15, and then connected to the corresponding hot water supply point through the connecting pipe 16.

[0025] During this process, when the staff needs to clean the filter screen 33, they can connect water to the connecting pipe 16 and change the direction of the water flow by controlling the water flow control component 2. At this time, the water flowing in from the connecting pipe 16 will be discharged outward through the filter screen 33 into the filter tank 31. In this process, the particles and impurities attached to the connecting pipe 32 can be removed.

[0026] It is worth mentioning that the number of connecting pipes 16 in this embodiment is two, one end of which is connected with the drain pipe 15, and the other end is used to connect the hot water use end, and the other end is used to connect the water source required for cleaning the filter screen 33.

[0027] The technical effects brought by the above embodiment are: by setting the filter assembly 3, the pipe can be effectively filtered, avoiding damage to the equipment inside the unit due to the presence of rust and other impurities during use, and shortening the service life of the equipment; by setting the discharge pipe 34 inserted into the inside of the filter screen 33, it can effectively clean the filter screen 33 during use, thereby avoiding the occurrence of blockage after long-term use.

[0028] As a preferred technical solution in this embodiment: the bottom of the filter tank 31 is also provided with a blowdown pipe 35 for draining water, and the other end of the blowdown pipe 35 is connected with the second branch pipe 22. In actual use, when the worker starts to clean the communicating pipe 32, the impurities washed off from the filter screen 33 in the filter tank 31 can be effectively discharged by opening the blowdown pipe 35, thereby ensuring the convenience of cleaning the communicating pipe 32 and effectively ensuring the convenience during use. It is worth mentioning that the blowdown pipe 35 in this embodiment is provided with a valve for controlling the on-off.

[0029] As one preferred technical solution in the embodiment, the water flow control assembly 2 comprises a first branch pipe 21 and a second branch pipe 22 for connection, one end of the first branch pipe 21 and the second branch pipe 22 is in communication with the water outlet pipe 12, and the other end of the first branch pipe 21 and the second branch pipe 22 is connected with 25, which is in communication with the heat exchanger 13, the first branch pipe 21 is provided with a circulating water pump 23 for controlling water flow circulation and a second control valve 24 for controlling water flow on-off. The water outlet pipe 12 is provided with a first control valve 121 for controlling water flow on-off and a drain outlet 122 for draining water. In actual use, when the staff controls the water heater to work normally, first, one of the second control valves 24 is closed, then the staff controls the circulating water pump 23 to drive the water in the water storage tank 1 to realize the effect of circulation, the water flow control assembly 2 is used for heat exchange, and the filtering assembly 3 is used for filtering effect, finally, the connecting pipe 16 is connected to the place where hot water is needed. When the internal part of the filtering assembly 3 needs to be automatically cleaned, the staff can control one of the second control valves 24 to close the first branch pipe 21, control the other second control valve 24 to open the second branch pipe 22, open the drain outlet 122 provided on the water outlet pipe 12 and close the first control valve 121, at this time, the staff can control the circulating water pump 23 to control the water flow from the filtering assembly 3 to the water outlet pipe 12 through the second branch pipe 22, and then discharged through the drain outlet 122 provided on the water outlet pipe 12, so as to realize the effect of discharging the sewage after cleaning.

[0030] The technical effects brought by the above embodiment are that the second branch pipe 22 is provided, which can effectively realize the effect of discharging the sewage after cleaning the filter screen 33, and ensures the convenience during cleaning the filter screen 33.
