Technical Field

[0001] This utility model relates to the field of electric water heater technology, specifically to an automatic scale cleaning device for electric water heaters. Background Technology

[0002] Electric water heaters are water heaters that use electricity as an energy source for heating. They are one of the three major types of water heaters, along with gas water heaters and solar water heaters. Electric water heaters can be divided into three types according to their heating power: storage type, instant type, and quick-heating type.

[0003] With the rapid development of technology, electric water heaters are being used in a wider range of scenarios and are now commonly found in transportation vehicles such as trains and high-speed trains. As their usage frequency continues to increase, cleaning the scale inside the heating chamber has become an important part of daily maintenance.

[0004] However, traditional cleaning methods usually require disassembling and transporting the entire equipment to the maintenance workshop, which is then completed by multiple people working together. This method is not only time-consuming and labor-intensive, but also prone to leaving blind spots in the cleaning process. Furthermore, improper operation may damage the equipment. In addition, conventional cleaning often relies heavily on chemical cleaning agents, and the resulting wastewater and chemical residues are discharged directly, causing significant environmental pollution. Utility Model Content

[0005] This invention provides an automatic scale cleaning device for electric water heaters. Through the synergistic action of a magnetic circulation pump and an adjustable pressure reducing valve, the flushing pressure can be adjusted according to the actual operating conditions of the electric water heater, effectively reducing scale residue and realizing the recycling of wastewater, thus reducing environmental impact. At the same time, the return wastewater is filtered by a filter element, which not only ensures the cleaning effect inside the electric water heater, but also facilitates the maintenance of the cleaning device by the operator. This solves the problems mentioned in the background art, such as the time-consuming and easily damaging nature of manual cleaning methods for electric water heaters.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Reference Figures 1-5 An automatic scale cleaning device for electric water heaters includes a water storage tank 1 fixedly connected to a movable base. The movable base consists of a fixed plate, pulleys, and casters. The pulleys and casters are installed at the bottom of the fixed plate, facilitating the movement and positioning of the cleaning device. A control box 2 fixedly connected to the movable base is located on one side of the water storage tank 1. The device also includes a magnetic circulation pump 3 fixedly installed inside the control box 2. The control box 2 has a control switch for controlling the magnetic circulation pump 3 to start. The input end of the magnetic circulation pump 3 is fixedly connected to a water supply pipe 4 connected to the water storage tank 1. The output end of the magnetic circulation pump 3 is fixedly connected to an adjustable pressure reducing valve 5 for controlling the water flow. The adjustable pressure reducing valve 5 can control the water flow rate to prevent excessive water flow impact from damaging the inside of the electric water heater. A filter element is installed inside the water storage tank 1 through a return water pipe. The filter element extends into the inner cavity of the water storage tank 1 and is used to filter the returned cleaning liquid, removing internal impurities and improving the cleaning quality of the circulating cleaning liquid.

[0020] Specifically, through the coordinated operation of the magnetic circulation pump 3 and the adjustable pressure reducing valve 5, the flushing pressure can be dynamically adjusted according to the actual operating conditions of the electric water heater, effectively reducing scale accumulation and residue, and realizing the recycling of wastewater, thereby reducing the impact on the environment. At the same time, the filter element filters the return wastewater, which not only ensures the cleaning effect inside the electric water heater, but also facilitates the maintenance and management of the cleaning device by the operator.

[0021] The return water pipe includes a circular pipe 6 that is fixedly connected to the water storage tank 1. Two connecting rods 61 are fixedly connected to the bottom of the circular pipe 6. A support plate 62 is fixedly connected between the bottoms of the two connecting rods 61. The support plate 62 is circular in shape.

[0022] Specifically, the return water pipe allows the cleaning solution containing scale to be guided back to the water storage tank 1, avoiding environmental pollution caused by direct discharge. At the same time, it can also limit the installation of the filter element, which helps to improve the efficiency of its maintenance and replacement.

[0023] The filter element includes a filter element 7 inserted into the round tube 6. The filter element 7 is an ion exchange resin filter element 7, model number: RC-D10, which is mainly used to remove and alleviate scale. The bottom of the filter element 7 abuts against the top of the support plate 62. The top of the filter element 7 is provided with a sealing cover 8, which is threaded onto the round tube 6. The sealing cover 8 is provided to prevent dust from entering the filter element 7 when the cleaning device is not in use.

[0024] Specifically, by setting up the filter element, one end of the external water pipe is connected to the outlet of the electric water heater, and the other end is inserted into the inlet of the filter element 7. This not only effectively filters out impurities in the cleaning solution, but also enables the positioning of the external water pipe, improving its stability during use.

[0025] A door 9 is rotatably mounted on the water storage tank 1. A sealing gasket 10 is fixedly connected to the door 9 and abuts against the opening of the water storage tank 1. The water storage tank 1 is provided with a buckle, and the movable fastener of the buckle is fixedly connected to the water storage tank 1. The fixed fastener of the buckle is fixedly connected to the door 9. The buckle is used to fix the door 9, which can increase the stability of the door 9 in use.

[0026] Specifically, by using the door 9 in conjunction with the sealing gasket 10, it is not only convenient for operators to clean and maintain the inside of the water storage tank 1, but also to effectively seal the water storage tank 1, preventing external dust from entering and avoiding contamination of the cleaning solution.

[0027] In this utility model, when cleaning scale inside the electric water heater, first take a connecting water pipe and connect its two ends to the water inlet of the electric water heater and the water outlet of the adjustable pressure reducing valve 5, respectively; then take another connecting water pipe and connect its two ends to the water outlet of the electric water heater and the water inlet of the filter element 7, respectively. After the two connecting water pipes are installed, use external clamps to fix the water pipes.

[0028] After the water pipes are fixed, the operator starts the magnetic circulation pump 3 through the switch on the control box 2 and adjusts the water flow speed using the adjustable pressure reducing valve 5. When the magnetic circulation pump 3 is working, it draws the cleaning liquid from the water storage tank 1 and pumps it into the electric water heater to achieve a thorough flushing of the inner cavity of the electric water heater, effectively removing the scale attached to the inner wall. After the scale dissolves, the wastewater enters the filter element 7 through the connecting water pipe. After being filtered by the filter element 7, the cleaning liquid and scale particles are separated. The system can circulate and continuously flush, thereby improving the cleaning effect inside the electric water heater.

[0029] As the usage time increases, the filter element 7 gradually becomes saturated and the filtration efficiency decreases. At this point, the operator can remove the filter element 7 from the round tube 6 and replace it with a new filter element 7 to restore and further improve the filtration performance of the cleaning device.

[0030] Components not described in detail in this article are existing technologies.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
