[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] See also Figure 1 , is a thyristor constant temperature electric heating hot water boiler disclosed in the embodiment of the present application, comprising a cabinet 1, the front side of the cabinet 1 is a control cabinet 11, and the rear side is a function cabinet 12, please refer to Figure 2 The function cabinet 12 is fixedly provided with an electric heating furnace 2, which includes a water storage tank. The function cabinet 12 is provided with a water supply pump 31, the output end of which is connected to the water storage tank, and the input end of which is connected to a water source. The function cabinet 12 is provided with a filter box 4, and a filter pump 32 is provided outside the filter box 4, the input end of which is connected to the water storage tank, and the output end of which is connected to the filter box 4. Please refer to Figure 3 A dispersion plate 41 and a filter plate 42 are installed in the filter box 4. The dispersion plate 41 is a porous plate. The filter plate 42 is located below the dispersion plate 41. A circulation pump 33 is also provided on the side of the filter box 4. The input end of the circulation pump 33 is connected to the filter box 4, and the output end is connected to the heating pipeline.

[0036] Specifically, there are minerals in tap water, which generate calcium carbonate, magnesium hydroxide, magnesium carbonate, calcium sulfate and other substances when heated, and form scale after aggregation and precipitation. A filter box 4 is arranged behind the water storage tank, and the heated water is filtered through the filter box 4 before entering the heating pipe.

[0037] In this way, by filtering the heated water, the possibility of scale components entering the heating pipes is reduced, thereby reducing the impact of scale on the heating pipes.

[0038] In some feasible ways, the electric heating furnace 2 and the control cabinet 11 are prior art and will not be described here. The functional cabinet 12 is a rectangular cabinet, and the filter box 4 can be selected as a rectangular box. A dispersion plate 41 and a filter plate 42 are installed in the filter box 4. The dispersion plate 41 is a porous plate, and the filter plate 41 is a filter material suitable for the particle size of scale particles. The filter plate 42 is installed below the dispersion plate 41. After the hot water enters the filter box 4 through the filter pump 32, it falls on the dispersion plate 41. When the dispersion plate 41 has a porous structure, the water flows to the filter plate 42 at various positions more evenly, so that all parts of the filter plate 42 participate in the filtration, thereby increasing the service life of the filter plate 42 and improving the filtration efficiency. The filtered water is sent to the heating pipe through the circulation pump 33, and then flows back to the water storage tank for circulation after passing through the heating pipe. Some losses will occur during the circulation process, and the water supply pump 31 is used to replenish the water in time to keep the water level in the water storage tank normal.

[0039] As a specific implementation of a thyristor constant temperature electric heating hot water boiler provided in the application, please refer to Figure 2 A muddy water fan blade 51 is rotatably installed in the water tank, and the rotating shaft of the muddy water fan blade 51 passes through the water tank and is connected to a rotating driving member 52.

[0040] Generally speaking, the substances that constitute scale are mainly produced after water is heated. When the water in the water tank is heated, some scale will be deposited. By setting the muddy water blades 51, the water is continuously stirred when it is heated, so that the substances that constitute scale cannot be deposited, and more of them follow the water flow into the filter box 4 to complete the filtration, thereby reducing the generation of scale in the water tank.

[0041] For further information, see Figure 4 The rotating driving member 52 includes a driving box 521, in which a driving impeller 522 is installed. A water inlet pipe and a water outlet pipe are respectively arranged on both sides of the driving box 521. The water inlet pipe is connected to the output end of the circulation pump 33, and the water outlet pipe is connected to the heating pipe. The water inlet pipe faces the blades of the driving impeller 522.

[0042] It should be understood that by providing the driving box 521 and the driving impeller 522 , the water flow of the circulating pump 33 drives the driving impeller 522 to rotate, thereby driving the muddy water blades 51 to rotate.

[0043] In some feasible embodiments, the driving box 521 is a rotating box body with a semicircular outer side. The output end of the circulating pump 33 passes through the driving box 521 in the tangential direction. The driving impeller 522 is coaxially connected to the muddy water blades 51. When the water flow of the circulating pump 33 hits the driving impeller 522, the driving impeller 522 rotates, driving the muddy water blades 51 to rotate.

[0044] As another specific implementation of a thyristor constant temperature electric heating hot water boiler provided in the application, please refer to Figure 3A plate changing port 401 is opened on one side of the filter box 4 , a plate changing frame 402 is slidably installed in the plate changing port 401 , the plate changing frame 402 is sealed and connected to the plate changing port 401 , and the filter plate 42 is installed on the plate changing frame 402 .

[0046] In some feasible embodiments, sliding grooves are provided on both sides of the position of the filter box 4 opposite to the plate changing port 401, and the plate changing frame 402 is a rectangular frame. The plate changing frame 402 can be slidably installed in the sliding grooves, and a rectangular plate is fixedly installed at one end of the plate changing frame 402 located on the outside of the filter box 4, and the rectangular plate is bolted and sealed to the filter box 4.

[0047] As a specific embodiment of a thyristor constant temperature electric heating hot water boiler provided in the application, a plurality of nozzles 421 are arranged in a linear array above the filter plate 42, the nozzles 421 are fixedly connected to the filter box 4, the nozzles 421 are connected to the output end of the circulation pump 33, and an electromagnetic valve is arranged between the nozzles 421 and the circulation pump 33.

[0048] It should be understood that by setting up the nozzle 421 controlled by the solenoid valve, after filtering for a period of time, the upper end of the filter plate 42 is flushed through the nozzle 421, and the scale attached to the top of the filter plate 42 is flushed to one side, reducing the blockage of the filter plate 42 and thereby reducing the maintenance of the filter plate 42.

[0049] In some feasible embodiments, the spraying direction of the nozzle 421 is parallel to the upper end surface of the filter plate 42 .

[0050] As a specific implementation of a thyristor constant temperature electric heating hot water boiler provided in the application, a water level gauge is provided on the inner side of the filter box 4 near the bottom, and the water level gauge is connected to the circulation pump 33 .

[0051] It should be understood that by setting a water level gauge to monitor the water level at the bottom of the filter box 4 and connecting the circulation pump 33, when the water level is lower than the warning water level, the circulation pump 33 is controlled to be suspended to reduce the possibility of air being sucked into the heating pipe.

[0052] Furthermore, a water level gauge is also installed near the top of the inner side of the filter box 4 , and the water level gauge is connected to the filter pump 32 , and the water level gauge is connected to an alarm device.

[0053] It should be understood that by setting a water level meter, the possibility of water overflow caused by untimely filtration of the filter plate 42 in the filter box 4 is reduced. When the water level is too high, the water level meter controls the filtration pump 32 to be paused and triggers an alarm to remind the staff to replace and clean the filter plate 42.

[0054] In some feasible embodiments, the water level meter is connected to the control part of the control cabinet 11 , and the feedback signal controls the circulation pump 33 or the filter pump 32 .
