Detailed implementation manners

[0039] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0040] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0041] For ease of description, spatial relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation other than the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or motion state change, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will subsequently be oriented as "above" or "over" other elements or features. Therefore, the exemplary term "below" can include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0042] In existing electric water heaters, the water inlet pipe directly feeds water into the inner tank of the electric water heater.

[0043] However, this method will impact the water layer in the inner tank of the electric water heater, resulting in a relatively low hot water output rate of the electric water heater.

[0044] In order to solve the technical problem in the prior art that the direct feeding of water into the inner tank of the electric water heater by the water inlet pipe leads to a relatively low hot water output rate of the electric water heater, the present application provides a water heater device that can reduce the impact on the water layer in the inner tank of the water heater when water enters through the water inlet pipe and improve the hot water output rate of the water heater.

[0045] Referring to Figures 1 - 17 , the present application provides a water heater device 01. The water heater device 01 includes a water heater inner tank 10 and a water inlet guiding structure 20. The water heater inner tank 10 is provided with a water inlet 11 and a water storage cavity 12. The water inlet guiding structure 20 includes a water inlet pipe 100 and a guiding component 200. The water inlet pipe 100 is provided with a water inlet end 110 and a water outlet end 120. The water outlet end 120 passes through the water inlet 11. The guiding component 200 is located in the water storage cavity 12 and is connected to the water outlet end 120. The water inlet end 110 is used to connect to an external water pipe.

[0046] In this embodiment, a diversion assembly 200 is provided at the water outlet end 120 of the water inlet pipe 100, so that the diversion assembly 200 diverts the water flowing out of the water outlet end 120 and then slowly enters the lower layer of the inner tank of the water heater. In this way, the impact on the water layer in the inner tank of the electric water heater when the water inlet pipe 100 intakes water can be reduced, thereby effectively improving the hot water output rate of the water heater. For example, the hot water output rate of the water heater can be increased to more than 90%.

[0047] In some possible implementation manners, the diversion assembly 200 includes a first diversion member 210, a second diversion member 220, a drain pipe 230, and a fixing member 240. The drain pipe 230 is sleeved on the outer periphery of the first diversion member 210, the second diversion member 220 is sleeved on the outer periphery of the drain pipe 230, the fixing member 240 includes a relatively arranged first connection end 241 and a second connection end 242. The first connection end 241 is connected to the water outlet end 120 of the water inlet pipe 100, the second connection end 242 passes through the water inlet 11 of the inner tank, and the second diversion member 220 is fixed to the second connection end 242.

[0048] Among them, the first diversion member 210 is a hollow pipe, which can be a diversion plug head. Water enters from the lower part, and water guiding holes 211 are provided in the upper part. The inside of the first diversion member 210 is a first flow channel.

[0049] The drain pipe 230 can be made of stainless steel, and water outlet holes 231 are provided on the pipe wall. The space between the first diversion member 210 and the drain pipe 230 is a second flow channel.

[0050] The second diversion member 220 can be an umbrella-shaped plastic cap. The second diversion member 220 is fixed on the fixing member 240 and cooperates with the drain pipe 230 and the first diversion member 210. The space between the drain pipe 230 and the second diversion member 220 is a third flow channel.

[0051] In some embodiments, the fixing member 240 adopts a hollow design. In this way, not only can water discharge be facilitated, but also the fixing member 240 can have a certain elasticity. When installing the water nozzle into the inner tank, the diameter of the fixing member 240 can be compressed, which is convenient for installation.

[0052] In some embodiments, when the second diversion member 220 is sleeved on the outer periphery of the fixing member 240, the second diversion member 220 can be fixed by the limiting block 246 on the fixing member 240.

[0053] Refer to Figure 8 , when the water heater is working, the incoming water flow passes through the first flow channel of the first diversion member 210 from the joint of the water inlet pipe 100, is buffered and flows into the second flow channel through the water guiding holes 211 on the first diversion member 210, flows into the third flow channel from the water outlet holes 231 of the drain pipe 230 after the flow rate and pressure are reduced, and finally flows out from the second diversion member 220 and slowly enters the water heater.

[0054] In this way, by providing the first flow guide member 210, the second flow guide member 220, and the drain pipe 230, the incoming water flow at the water outlet end 120 of the water inlet pipe 100 can be buffered before flowing into the inner tank of the water heater, thereby reducing the impact on the water layer in the inner tank 10 of the electric water heater when the water inlet pipe 100 admits water, protecting the water layer distribution in the inner tank 10 of the water heater, and effectively improving the hot water output rate of the water heater.

[0055] In some possible embodiments, the flow guide assembly 200 further includes a scale inhibitor 250 and a scale inhibitor cover 260. The second flow guide member 220 is provided with a first receiving groove 221, the scale inhibitor 250 is located in the first receiving groove 221, the scale inhibitor cover 260 is provided at the top of the second flow guide member 220, and is detachably connected to the second flow guide member 220 and the fixing member 240.

[0056] The water in the inner tank 10 of the water heater usually contains minerals such as calcium and magnesium. During the heating process, these minerals are likely to precipitate and form hard water scale, which will reduce the heating efficiency of the water heater.

[0057] By providing the scale inhibitor 250 in the second flow guide member 220, the formation of water scale (mineral deposits) on the inner tank can be prevented or reduced.

[0058] In addition, by providing the scale inhibitor cover 260, the overflow of the scale inhibitor 250 stored inside the second flow guide member 220 can be prevented.

[0059] In addition, the scale inhibitor cover 260 is detachably connected to the second flow guide member 220 and the fixing member 240, facilitating the assembly and replacement of the scale inhibitor cover 260.

[0060] In some possible embodiments, the scale inhibitor cover 260 is provided with an installation hole 263, the second connection end 242 of the fixing member 240 is provided with a limiting portion 2421, the second connection end 242 passes through the installation hole 263, and the limiting portion 2421 abuts against the scale inhibitor cover 260. In this way, the connection stability between the scale inhibitor cover 260 and the fixing member 240 can be improved.

[0061] In some possible embodiments, the second flow guide member 220 is provided with a second receiving groove 228 and a first locking structure 222. The second receiving groove 228 is disposed opposite to the first receiving groove 221. The first locking structure 222 is disposed in the second receiving groove 228. The first locking structure 222 includes a lock catch 2221 and an abutting portion 2222. The scale inhibitor cover 260 is provided with a locking groove 261. When the scale inhibitor cover 260 is connected to the second flow guide member 220, the lock catch 2221 is embedded in the locking groove 261, and the scale inhibitor cover 260 abuts against the abutting portion 2222.

[0062] In some possible embodiments, the latch 2221 is provided with a guiding inclined surface 21, and the first locking structure 222 can push the scale inhibitor cover 260 to move radially along the second flow guide member 220 through the guiding inclined surface 21.

[0063] In this way, by providing the guiding inclined surface 21 on the latch 2221, the scale inhibitor cover 260 can be guided to move radially along the second flow guide member 220, so that when the scale inhibitor cover 260 touches the guiding inclined surface 21 of the second flow guide member 220, it can be automatically aligned and inserted, reducing the error of manual alignment and improving the convenience of assembling the scale inhibitor cover 260.

[0064] In some possible embodiments, the scale inhibitor cover 260 is provided with a water permeable hole 262, and the water permeable hole 262 is arranged close to the scale inhibitor 250.

[0065] In this way, the water in the water storage cavity 12 of the water heater inner tank 10 can fully contact the scale inhibitor 250 in the second flow guide member 220 through the water permeable hole 262 of the scale inhibitor cover 260.

[0066] In some possible embodiments, the scale inhibitor cover 260 may be provided with a limiting hole 264, and the second flow guide member 220 may be provided with a limiting post 226. The limiting post 226 is provided with a protruding portion 2261. When the scale inhibitor cover 260 is connected to the second flow guide member 220, the protruding portion 2261 abuts against the scale inhibitor cover 260. In this way, the cooperation between the limiting hole 264 and the limiting post 226 can improve the connection stability between the scale inhibitor cover 260 and the second flow guide member 220, and prevent the scale inhibitor cover 260 from loosening or shifting due to vibration or other external forces.

[0067] In some possible embodiments, the second flow guide member 220 may be provided with a first threaded hole 227, and the scale inhibitor cover 260 may be provided with a second threaded hole 265. In this way, through the first threaded hole 227 and the second threaded hole 265, the scale inhibitor cover 260 can be threadedly connected to the second flow guide member 220, thereby further improving the connection stability between the scale inhibitor cover 260 and the second flow guide member 220.

[0068] In some possible embodiments, the second flow guide member 220 is provided with a through hole 223 and a plurality of flow guiding portions. The plurality of flow guiding portions are arranged in the second receiving groove 228 and are spaced apart circumferentially along the through hole 223.

[0069] In some possible embodiments, the flow guiding portion includes a plurality of first flow guiding portions 224 and a plurality of second flow guiding portions 225. The plurality of first flow guiding portions are close to the through hole 223 and are spaced apart circumferentially along the through hole 223. The second flow guiding portions 225 are spaced apart from the through hole 223. The arc length of the first flow guiding portion 224 is less than the arc length of the second flow guiding portion 225.

[0070] In some possible embodiments, the diversion portion is arranged in an arc shape. The diversion portion includes a concave surface 22, a convex surface 23, and a reinforcing rib 24. The reinforcing rib 24 is disposed on the concave surface 22 and fixed to the bottom end of the second diversion member 220. The convex surface 23 faces the through hole 223.

[0071] Since the convex surface 23 has a relatively large radius of curvature, it can more effectively disperse the impact force of the water flow. When the high-speed water flow hits the convex surface 23, due to its curved surface characteristics, the impact force will be dispersed over a larger area, thereby reducing local stress concentration.

[0072] Moreover, by arranging the convex surface 23 to face the through hole 223, the water flow can flow from the mounting hole 263 of the second diversion member 220 to the first diversion portion 224 and be diffused to the second diversion portion 225 through the first diversion portion 224.

[0073] In addition, by providing the reinforcing rib 24, the overall rigidity and anti-deformation ability of the diversion portion can be improved.

[0074] By making the arc length of the first diversion portion 224 shorter than that of the second diversion portion 225, the water flow can be quickly and evenly dispersed, preventing the water flow from concentrating in a certain area. That is, the shorter arc length of the first diversion portion 224 enables the water flow to be dispersed within a short time.

[0075] The longer arc length of the second diversion portion 225 allows more water flow to adhere to the second diversion portion 225, thereby enhancing the flow retardation effect of the second diversion portion 225.

[0076] In some possible embodiments, the fixing member 240 includes a fixing portion 243 and a connecting portion 244 that are connected to each other. The connecting portion 244 is located at the first connection end 241, and the fixing portion 243 is located at the second connection end 242. The connecting portion 244 is provided with a convex rib 245, and the diameter of the connecting portion 244 is smaller than the diameter of the fixing portion 243.

[0077] Since in some production processes, the water nozzle of the inner tank is not enameled, by providing the convex rib 245 on the connecting portion 244, the contact between the water nozzle of the inner tank and water can be reduced, thereby delaying the corrosion of the water nozzle.

[0078] In addition, in the production process of the inner tank, there may be irregular small enamel particle protrusions inside the water nozzle of the inner tank. Therefore, the diameter of the connecting portion 244 is smaller than the diameter of the fixing portion 243. That is, the diameter reduction can prevent the fixing member 240 from being lifted by small enamel particles to form an indentation, which may further cause the inner diameter of the fixing member 240 to decrease, making it difficult to disassemble and assemble the water inlet pipe 100.

[0079] In some possible embodiments, a joint of the water inlet pipe 100 may be provided. The joint of the water inlet pipe 100 is connected to the water inlet pipe 100. The joint of the water inlet pipe 100 may be made of an insulating material, preferably a hydrophilic insulating material such as PPR, PA, or PP. A return water waterway flow channel may be provided inside. The joint of the water inlet pipe 100 may include an internal thread connecting member 101 and an external thread connecting member 102. The internal thread connecting member 101 may be threadedly connected to the water inlet 11 of the inner tank.
