Description

Technical Field

[0001] The invention relates to the technical field of water heaters, and in particular to a water storage heater capable of conveniently treating scale. Background Art

[0002] During the long-term use of the heater, due to water quality problems, scale is easily accumulated in its inner tank. These scales not only affect the thermal efficiency of the equipment, but may also cause damage to the equipment or shorten its service life. There are two main traditional descaling methods: The first is physical cleaning: that is, after disassembling the equipment, use a high-pressure water gun to directly flush the internal scale. Although this method can directly remove most of the visible scale, the operation is complicated and time-consuming, especially for some equipment with complex structures (such as compact inner tank design, dense pipes, etc.). The disassembly process is very cumbersome, and frequent disassembly and assembly may cause damage to the equipment, reducing its sealing and overall performance. The second is chemical cleaning: that is, dissolving the scale by injecting a descaling agent into the inner tank. This method is suitable for large-capacity containers that cannot be easily disassembled or heaters with complex built-in structures. However, for those cases where the scale on the surface of the inner tank is severe and stubborn, relying solely on descaling agents may not be able to completely remove all the scale, and sometimes mechanical means are required to assist in cleaning. Summary of the invention

[0011] Further description, it also includes filter screens symmetrically distributed along the guide frame, the filter screens are fixedly connected to the inlet of the guide frame, and the fan blades are in contact with adjacent filter screens.

[0012] Further explanation, the sewage discharge assembly includes a sewage discharge pipe, the sewage discharge pipe is fixedly connected to one side of the water tank, the inlet of the sewage discharge pipe is connected to the inner tank, a cylinder is fixedly connected to one side of the inner tank close to the sewage discharge pipe, the telescopic rod of the cylinder is fixedly connected to a baffle, and the baffle blocks the inlet of the sewage discharge pipe.

[0013] It is further explained that the sewage discharge component also includes a liquid level sensor, which is fixed to the guide frame and electrically connected to the water pump through the controller.

[0014] The beneficial effects of the present invention are: 1. The present invention utilizes the impact force of the descaling solution to make the rotating nozzle rotate and spray the descaling solution, which can perform multi-directional flushing of the scale inside the entire inner tank, combining the advantages of physical cleaning and chemical cleaning, eliminating the disadvantages of each cleaning, and improving the cleaning effect. At the same time, the fixed nozzle and the rotating nozzle spray each other to prevent scale from forming on the fixed nozzle and the rotating nozzle, and the flushed scale can be discharged in time.

[0015] 2. In order to overcome the problem of weakened flushing force caused by gravity, the present invention uses a rotating ring to push and pull two adjustment plates with the help of a guide groove to form an automatic control system, so that when the flushing nozzle of the rotating nozzle rotates from bottom to top, the spray volume of the descaling solution is increased, and at the same time the rotation speed of the rotating nozzle is slowed down, thereby extending the flushing time and enhancing the flushing effect.

At the same time, the sewage nozzle is connected through the pressure relief pipe, so that the descaling solution in the rotating nozzle is finally discharged to the sewage nozzle, thereby increasing the impact force at the sewage nozzle and improving the sewage discharge effect.

[0018] 5. The present invention provides front and rear guide blocks so that the dirt flowing to the right in the inner tank can be more accurately introduced into the sewage discharge assembly, thereby accelerating the discharge of the dirt.

[0019] 6. The present invention can prevent scale impurities in the inner tank from entering the guide frame by setting a filter, thereby preventing scale impurities from entering the fixed nozzle and the rotating nozzle, and further preventing the respective bell-mouth nozzles and the flushing nozzles from being blocked. At the same time, the impurities on the filter can be automatically scraped off when the fan blades rotate, thereby keeping the filter clean, avoiding additional manual cleaning work, and ensuring the normal operation of the system.

[0020] 7. After the rotating nozzle rotates and cleans for a period of time, the present invention controls the movement of the baffle frame through the cylinder to achieve rapid sewage discharge, reducing the time cost of downtime maintenance. The liquid level sensor is used to monitor the liquid level in the inner tank and control the operation of the water pump accordingly, realizing automated management and improving the safety and convenience of operation.

DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0036] Embodiment 1: A water storage heater with convenient scale treatment, such as Figures 1 to 5As shown, it includes a base 101, a water tank 102 is fixedly connected to the top of the base 101, an inner tank 103 is fixedly connected to the water tank 102, a pipe is fixedly connected to the upper left part of the water tank 102, the pipe penetrates into the inner tank 103, and the descaling agent and water are poured into the inner tank 103 through the pipe, a guide frame 104 is fixedly connected to the lower part of the water tank 102, the right side of the guide frame 104 is connected to the inner tank 103, a water pump 105 is fixedly connected to the water tank 102, the water pump 105 is connected to the guide frame 104, a sewage nozzle 106 is fixedly connected to the lower left part of the inner tank 103, at least one heating pipe 107 is fixedly connected to the water tank 102, the heating pipe 107 penetrates into the inner tank 103, a fixed nozzle 108 is fixedly connected to the inner tank 103, and the inner tank 103 The internal rotation is connected with a rotating nozzle 109 which is symmetrically distributed along the front and rear of the fixed nozzle 108. The fixed nozzle 108 is located between the front and rear rotating nozzles 109. The sewage nozzle 106, the fixed nozzle 108 and the rotating nozzle 109 are all connected to the left side of the guide frame 104. The fan blade 110 is fixedly connected to the right side of the rotating nozzle 109. The fixed nozzle 108 is provided with six groups of bell-mouth nozzles 111 which are symmetrically distributed along the front and rear of the fixed nozzle 108. The rightmost bell-mouth nozzle 111 faces the adjacent fan blade 110. The diameter of the rightmost bell-mouth nozzle 111 is larger than the diameters of the other bell-mouth nozzles 111. The rotating nozzle 109 is provided with six flushing nozzles, and the flushing nozzles and the bell-mouth nozzles 111 are staggered.

[0037] When the heater stops heating, the inner tank 103 can be descaled, and the specific descaling operation is as follows: first, the descaling agent is poured into the inner tank 103 through the pipeline, and then the inner tank 103 is filled with water through the pipeline. The descaling agent and water are mixed to obtain a descaling solution. Then, the water pump 105 is started. The water pump 105 draws the descaling solution in the inner tank 103 through the guide frame 104 to the sewage nozzle 106, the fixed nozzle 108 and the rotating nozzle 109. The descaling solution in the fixed nozzle 108 flows to the right to the two larger-diameter trumpet nozzles 111 on the front and rear of the rightmost side, and is sprayed onto the fan blades 110 on the front and rear sides respectively. The impact force of the descaling solution causes the fan blades 110 to rotate, and the fan blades 110 drive the rotating nozzle 109 to rotate synchronously The rotating nozzle 109 drives the multiple flushing nozzles thereon to rotate, so that the descaling solution in the rotating nozzle 109 is rotated and sprayed out. At the same time, the descaling solution in the fixed nozzle 108 is sprayed out through the multiple trumpet-mouth nozzles 111 with smaller diameters on the front and rear sides thereof during the process of flowing to the trumpet-mouth nozzle 111 with larger diameter on the far right, and the rotating nozzle 109 on the front and rear sides are respectively flushed. The descaling solution sprayed by the flushing nozzles of the rotating nozzle 109 can also flush the fixed nozzle 108. In addition, the flushed dirt is settled at the bottom of the inner tank 103 due to gravity. The descaling solution sprayed by the sewage nozzle 106 can flush the scale settled at the bottom of the inner tank 103 to the right into the sewage assembly for discharge outside the heater.

[0038] In summary, the present invention utilizes the impact force of the descaling solution to cause the rotating nozzle 109 to rotate and spray out the descaling solution, so as to perform multi-directional flushing of the scale inside the entire inner tank 103, combining the advantages of physical cleaning and chemical cleaning, eliminating the disadvantages of each cleaning, and improving the cleaning effect. At the same time, the fixed nozzle 108 and the rotating nozzle 109 spray each other to prevent scale from forming on the fixed nozzle 108 and the rotating nozzle 109, and the flushed scale can be discharged in time through the sewage discharge component.

[0039] like Figure 6 and Figure 7 As shown, it also includes an adjustment plate 201 symmetrically distributed along the guide frame 104. The adjustment plate 201 is slidably connected to the guide frame 104, and the adjustment plate 201 is slidably connected to the fixed nozzle 108. A rotating ring 202 is fixedly connected to the left side of the rotating nozzle 109, and a guide groove is opened on the right side of the rotating ring 202. The rotating ring 202 is slidably connected to the adjacent adjustment plate 201 through the guide groove. When the flushing nozzle of the rotating nozzle 109 rotates from bottom to top, the rotating ring 202 pushes the adjustment plate 201 to slide close to the fixed nozzle 108 through the guide groove.

[0040] Since the descaling solution is not only pushed by the pressure provided by the water pump 105, but also decelerated by the gravity when the flushing nozzle of the rotating nozzle 109 rotates from bottom to top, the flushing force is weakened, thereby weakening the flushing effect. In order to overcome the influence of gravity, when the flushing nozzle of the rotating nozzle 109 rotates from bottom to top, the amount of the descaling solution sprayed is increased, and the rotation speed of the rotating nozzle 109 is slowed down, so as to prolong the flushing time and enhance the flushing effect. The specific operation is as follows: When the rotating nozzle 109 rotates, it drives the rotating ring 202 to rotate synchronously. When the flushing nozzle of the rotating nozzle 109 rotates from bottom to top, the rotating ring 202 pushes the two adjustment plates 201 closer to each other through the guide groove, so that the distance between the two adjustment plates 201 is reduced, thereby reducing the amount of descaling solution entering the fixed nozzle 108 from the guide frame 104, resulting in an increase in the amount of descaling solution entering the rotating nozzle 109 from the guide frame 104, thereby enhancing the flushing force of the rotating nozzle 109. At the same time, the flushing force of the fixed nozzle 108 is weakened, which reduces the rotation speed of the fan blade 110, thereby slowing down the rotation speed of the rotating nozzle 109 and extending the flushing time of the rotating nozzle 109. Conversely, when the flushing nozzle of the rotating nozzle 109 rotates from top to bottom, the flushing force of the rotating nozzle 109 is weakened and the flushing time of the rotating nozzle 109 is shortened.

[0041] like Figure 8 and Fig. 9As shown, it also includes a pressure relief pipe 301, the right side of the pressure relief pipe 301 is connected to the rotating nozzle 109, the left side of the pressure relief pipe 301 is connected to the sewage nozzle 106, and two pressure valves 302 are fixedly connected to the upper right side of the pressure relief pipe 301, and the two pressure valves 302 correspond to the two rotating nozzles 109 respectively.

[0042] Although the flushing nozzle of the rotating nozzle 109 can be flushed by the descaling solution sprayed from the bell-mouth nozzle 111, there is still the possibility of the flushing nozzle being blocked during long-term use. When the flushing nozzle is blocked and the internal hydraulic pressure of the rotating nozzle 109 increases, the pressure valve 302 is opened under pressure, and the descaling solution in the rotating nozzle 109 enters the pressure relief pipe 301 through the pressure valve 302, which has the effect of timely pressure relief protection, thereby increasing the service life of the rotating nozzle 109 and preventing the rotating nozzle 109 from rupture due to pressure. In addition, the sewage nozzle 106 is connected through the pressure relief pipe 301, so that the descaling solution in the rotating nozzle 109 is finally discharged to the sewage nozzle 106, thereby increasing the impact force at the sewage nozzle 106 and improving the sewage discharge effect.

[0043] like Fig.10 and Fig.11 As shown, it also includes a guide block 401 symmetrically distributed along the front and rear of the guide frame 104, and the guide block 401 is fixedly connected to the right side of the guide frame 104. By setting the front and rear guide blocks 401, the dirt flowing to the right in the inner tank 103 can be more accurately introduced into the sewage discharge component, thereby accelerating the discharge of the dirt. The inlet of the guide frame 104 is fixedly connected with a filter screen 402 symmetrically distributed along the guide frame 104, and the fan blade 110 is in contact with the adjacent filter screen 402. By setting the filter screen 402, the scale impurities in the inner tank 103 can be prevented from entering the guide frame 104, thereby preventing the scale impurities from entering the fixed nozzle 108 and the rotating nozzle 109, thereby preventing the respective bell-mouth nozzles 111 and the flushing nozzles from being blocked. In addition, when the fan blade 110 rotates, it will scrape off the impurities on the filter screen 402 in time, thereby achieving the effect of automatically cleaning the filter screen 402.

[0044] like Figures 11 to 13As shown, the sewage discharge assembly includes a sewage discharge pipe 501, which is fixedly connected to the right side of the water tank 102. The inlet of the sewage discharge pipe 501 is connected to the inner tank 103. The right side of the inner tank 103 is fixedly connected to a cylinder 502, and the telescopic rod of the cylinder 502 is fixedly connected to a blocking frame 503. The blocking frame 503 blocks the inlet of the sewage discharge pipe 501. After the rotating nozzle 109 rotates and cleans for a period of time, the telescopic rod of the cylinder 502 is controlled to extend to the right, so that the blocking frame 503 moves to the right until it no longer blocks the inlet of the sewage discharge pipe 501. At this time, the sewage accumulated in the inner tank 10 The scale on the right side is quickly discharged into the drain pipe 501, and then discharged out of the heater through the drain pipe 501. A liquid level sensor 504 is fixedly connected to the guide frame 104. The liquid level sensor 504 is electrically connected to the water pump 105 through the controller. When the scale is discharged into the drain pipe 501, a small amount of descaling agent solution in the inner tank 103 will be discharged along with the scale. When the liquid level of the descaling agent solution in the inner tank 103 drops to the liquid level sensor 504, the liquid level sensor 504 controls the water pump 105 to stop in time through the control module.
