[0019] The following is combined with Figure 1-6 This application is described in further detail.

[0020] The present application embodiment discloses a water heater heat dissipation component. Figure 1 and Figure 2 The water heater heat dissipation component includes an inner tank 1 and a heating plate 2. The inner tank 1 is rectangular and fits on the heating plate 2. Two inner tanks 1 are provided and are respectively located on both sides of the heating plate 2. The inner tank 1 is provided with a water inlet pipe 3 and a water outlet pipe 4. The water inlet pipe 3 and the water outlet pipe 4 are both connected to the inner tank 1. Combination Figure 3 and Figure 4A heat sink 5 is arranged in the inner tank 1. The heat sink 5 is fixedly arranged on the surface of the inner tank 1 that is attached to the electric heating plate. The heat sink 5 includes a bottom plate 51 and a plurality of heat conducting plates 52. The bottom plate 51 is fixedly arranged on the surface of the inner tank 1 that is attached to the electric heating plate. The heat conducting plates 52 are arranged on the bottom plate 51. The plurality of heat conducting plates 52 are parallel to each other and flow channels 6 are left between them. Under the action of the flow channels 6, cold water is convenient to flow in the gaps between the heat sinks 5, thereby increasing the contact area between the cold water and the heat conducting plates 52, and improving the heating efficiency of the cold water. The heating plate 2 heats the bottom wall of the inner tank 1 and transfers the heat to the heat conducting plates 52, and the heat conducting plates 52 heat the cold water.

[0021] When heating cold water, start the heating plate 2, which heats the inner tank 1. Then, inject cold water into the inner tank 1 through the water inlet pipe 3. After the cold water enters the inner tank 1, it enters between the heat conducting plates 52. The heating plate 2 transfers the heat through the inner tank 1 to the bottom plate 51 and the heat conducting plates 52, and then to the cold water, thereby heating the cold water. Since the heat sink 5 has good thermal conductivity, it can quickly transfer the heat inside the water heater to the water flow, thereby improving the heating efficiency of the water heater.

[0022] Reference Figure 4 Due to the obstruction of the heat conducting plate 52, the cold water cannot be smoothly injected into the inner tank 1. Therefore, in the embodiment of the present application, an arc groove 7 is provided on the heat conducting plate 52, and the arc groove 7 is directly opposite to the water inlet pipe 3 and the water outlet pipe 4. The cold water injected into the inner tank 1 through the water inlet pipe 3 flows from the arc groove 7 into the space between the heat conducting plates 52; under the action of the arc groove 7, there is a certain gap between the bottom wall of the arc groove 7 and the wall of the inner tank 1, which facilitates the injection of cold water into the inner tank 1. The cold water passes through the buffer of the arc groove 7 and then enters the flow channel 6 between the heat conducting plates 52, thereby facilitating the injection of cold water into the inner tank 1.

[0023] Reference Figure 4 In order to further increase the contact area between the cold water and the heat conducting plate 52, a plurality of dividing grooves 8 are provided on the plurality of heat conducting plates 52. The length direction of the dividing grooves 8 is perpendicular to the heat conducting plate 52. The plurality of dividing grooves 8 are parallel to each other and are spaced apart on the heat conducting plate 52. After the cold water is injected into the inner tank 1, the cold water first enters the arc groove 7, and then flows along the flow channel 6. When the cold water flows to the dividing grooves 8, the cold water enters the remaining flow channels 6 along the dividing grooves 8, which facilitates the heat conducting plate 52 to heat the cold water.

[0024] Reference Figure 3 In order to facilitate the installation of the heating plate 2 and the inner pot 1, two clamping plates 9 are also included. The inner pot 1 on both sides of the heating plate 2 is clamped between the two clamping plates 9, and the outer side of the inner pot 1 is attached to the clamping plates 9. The two clamping plates 9 are fixedly connected by bolts 10; after the heating plate 2 and the inner pot 1 are attached, the two clamping plates 9 are placed on both sides of the inner pot 1, and then the two clamping plates 9 are clamped by bolts 10, so that the heating plate 2 and the inner pot 1 are fixedly installed, and the operation is simple and convenient.

[0025] Reference Figure 4 , Figure 5 and Figure 6 When the inner tank 1 heats the cold water for a long time, the calcification in the cold water forms more scale on the bottom plate 51 and the heat conducting plate 52, which results in a smaller contact area between the cold water and the heat conducting plate 52, and the scale has a certain obstruction effect on the flow channel 6, resulting in a decrease in the heating efficiency of the cold water; at the same time, the heat sink 5 is located in the inner tank 1, which makes it impossible to conveniently remove the heat sink from the inner tank 1, thereby making it impossible to conveniently clean the heat sink 5. Therefore, in the embodiment of the present application, a scraper 11 is provided between the heat conducting plates 52, and the scraper 11 is rectangular or long, and both sides of the scraper 11 are The scraper 11 is fitted with the heat conducting plate 52 and slides along the length direction of the heat conducting plate 52. A driving device 12 is provided in the inner tank 1 for driving the scraper 11 to slide and scrape off scale on the surface of the heat conducting plate 52. When the heat sink 5 has been used for a long time, the scraper 11 is driven by the driving device 12 to move along the flow channel 6. When the scraper 11 moves in the flow channel 6, the scale on the surface of the heat conducting plate 52 is scraped off. At the same time, cleaning water is injected into the inner tank 1, and the cleaning water is used to rinse the scraped scale, so that the scraped scale is removed from the inner tank 1, thereby restoring the heating efficiency of the heat conducting plate 52 for cold water.

[0026] Reference Figure 4 , Figure 5 and Figure 6 In the embodiment of the present application, the driving device 12 includes a reel 121 rotatably arranged on the side wall of the inner tank 1, two reel 121 are arranged and are respectively located at both ends of the heat conducting plate 52, the driving device 12 also includes a pull rope 122 reeled on the reel 121, the pull rope 122 has high temperature resistance, corrosion resistance and high strength physical and chemical properties, the pull rope 122 is located between the heat conducting plates 52 and is fixedly arranged on the scraper 11, and the driving device 12 also includes a driving member for driving the reel 121 to rotate and pull the scraper 11 to slide; Reference Figure 4 , Figure 5 and Figure 6 The driving member includes a fan blade 123 arranged on a fixed winding shaft 121. The shell of the inner tank 1 is provided with a water inlet channel 13. The water inlet channel 13 is located on the end surface of the shell of the inner tank 1. The water inlet channel 13 includes two horizontal channels 131 and a vertical channel 132 arranged between the horizontal channels 131. The fan blade 123 is eccentrically arranged in the horizontal channel 131. Cleaning water is injected into the water inlet channel 13 and enters the vertical channel 132 to impact the fan blade 123 and drive the winding shaft 121 to rotate.

[0027] When scraping off the scale on the heat conduction plate 52, cleaning water is injected into the water inlet channel 13, and the cleaning water is injected into the vertical channel 132 through the horizontal channel 131, and impacts the fan blades 123, thereby driving the winding shaft 121 to rotate. The winding shaft 121 rotates to reel in or release the pull rope 122, thereby driving the scraper 11 to move in the flow channel 6, thereby scraping off the scale on the heat conduction plate 52. The operation is simple and convenient.

[0028] Reference Figure 4 , Figure 5 and Figure 6 In order to facilitate the removal of the scraped scale by cleaning water after scraping, a water passage 14 is provided on the scraper 11, and the water passage 14 is parallel to the length direction of the heat conducting plate 52; at the same time, under the action of the water passage 14, the cold water injected into the inner tank 1 through the water inlet pipe 3 can enter the flow channel 6 through the water passage 14.

[0029] Reference Figure 4 , Figure 5 and Figure 6 When there is a lot of scale on the heat conduction plate 52, the resistance of the scraper 11 is large, which may make it difficult for the cleaning water and the fan blades 123 to drive the scraper 11 to move in the flow channel 6. Therefore, in the embodiment of the present application, the driving member also includes a forced rotation member, which includes a cross bar 124 arranged in the horizontal channel 131 and a vertical bar 125 arranged in the vertical channel 132. The forced rotation member also includes a bevel gear 126. The bevel gear 126 is located at the ends of the cross bar 124 and the vertical bar 125 and meshes with each other. The bevel gear 126 is also located on the vertical bar 125 and the winding shaft 121 and meshes with each other; when the cleaning water cannot drive the winding shaft 121 to rotate, the cross bar 124 is rotated. Under the action of the bevel gear 126, the cross bar 124 drives the vertical bar 125 to rotate, and the rotation of the vertical bar 125 drives the winding shaft 121 to rotate forcibly, thereby driving the scraper 11 to move out of the flow channel 6.

[0030] Reference Figure 4 , Figure 5 and Figure 6 In the embodiment of the present application, both ports of the water inlet channel 13 are provided with blocking members, and the water inlet end and the water outlet end of the water inlet channel 13 are sealed. The blocking members include plugging heads inserted into the two ports of the water inlet channel 13. The plugging heads are inserted into the water inlet channel 13 to block the water inlet channel 13, and the operation is simple and convenient.

[0031] The implementation principle of a water heater heat dissipation component in the embodiment of the present application is: When heating cold water, start the heating plate 2, which heats the inner tank 1. Then, inject cold water into the inner tank 1 through the water inlet pipe 3. After the cold water enters the inner tank 1, it enters between the heat conducting plates 52. The heating plate 2 transfers the heat through the inner tank 1 to the bottom plate 51 and the heat conducting plates 52, and then to the cold water, thereby heating the cold water. Since the heat sink 5 has good thermal conductivity, it can quickly transfer the heat inside the water heater to the water flow, thereby improving the heating efficiency of the water heater.

[0032] When the inner tank 1 has been used for a long time, cleaning water is injected into the water inlet channel 13, and the cleaning water is injected into the vertical channel 132 through the horizontal channel 131, and impacts the fan blades 123, thereby driving the reel 121 to rotate. The reel 121 rotates to reel in or release the pull rope 122, thereby driving the scraper 11 to move in the flow channel 6, thereby scraping off the scale on the heat conduction plate 52. At the same time, the injected cleaning water removes the scraped scale from the inner tank 1.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
