Detailed Implementation
[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0040] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0041] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.
[0042] In existing electric water heaters, the inlet pipe directly connects the water to the inner tank of the water heater.
[0043] However, this method can impact the water level inside the water heater, resulting in a relatively low hot water output rate.
[0044] In order to solve the technical problem that the hot water output rate of electric water heaters is relatively low due to the water inlet pipe directly introducing water into the inner tank of the water heater in the prior art, this application provides a water heater device that can reduce the impact of water entering the water inlet pipe on the water layer in the inner tank of the water heater and improve the hot water output rate of the water heater.
[0045] See Figures 1-17 This application provides a water heater device 01, which includes a water heater inner tank 10 and a water inlet guide structure 20. The water heater inner tank 10 is provided with a water inlet 11 and a water storage chamber 12. The water inlet guide structure 20 includes a water inlet pipe 100 and a guide assembly 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 guide assembly 200 is located in the water storage chamber 12 and connected to the water outlet end 120. The water inlet end 110 is used to connect to an external water pipe.
[0046] This embodiment provides a flow guiding component 200 at the outlet 120 of the inlet pipe 100. The flow guiding component 200 guides the water flowing out of the outlet 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 of the inner tank 10 of the electric water heater when water enters through the inlet pipe 100 can be reduced, thereby effectively improving the hot water output rate of the water heater, for example, increasing the hot water output rate of the water heater to more than 90%.
[0047] In some possible implementations, the flow guiding assembly 200 includes a first flow guiding member 210, a second flow guiding member 220, a drain pipe 230, and a fixing member 240. The drain pipe 230 is sleeved on the outer periphery of the first flow guiding member 210, and the second flow guiding member 220 is sleeved on the outer periphery of the drain pipe 230. The fixing member 240 includes a first connecting end 241 and a second connecting end 242 disposed opposite to each other. The first connecting end 241 is connected to the outlet end 120 of the water inlet pipe 100, and the second connecting end 242 passes through the water inlet 11 of the inner tank. The second flow guiding member 220 is fixed to the second connecting end 242.
[0048] The first guide element 210 is a hollow tube, which can be a guide plug. Water enters from the bottom and a water guide hole 211 is provided at the top. The first guide element 210 has a first flow channel inside.
[0049] The drain pipe 230 can be made of stainless steel, and the pipe wall is provided with a water outlet 231. The second flow channel is between the first flow guide 210 and the drain pipe 230.
[0050] The second guide 220 can be an umbrella-shaped plastic cap. The second guide 220 is fixed on the fixing member 240 and cooperates with the drain pipe 230 and the first guide 210. The third flow channel is between the drain pipe 230 and the second guide 220.
[0051] In some embodiments, the fixing member 240 adopts a hollow design, which not only facilitates water flow but also gives the fixing member 240 a certain degree of elasticity. When the water nozzle is installed into the inner tank, the diameter of the fixing member 240 can be compressed, making installation easier.
[0052] In some embodiments, when the second guide member 220 is sleeved on the outer periphery of the fixing member 240, the second guide member 220 can be fixed by the limiting block 246 on the fixing member 240.
[0053] See Figure 8 When the water heater is working, the incoming water flows through the inlet pipe 100 connector, through the first flow channel of the first guide member 210, and is buffered by the water guide hole 211 on the first guide member 210 before flowing into the second flow channel. After the flow rate and pressure are reduced, the water flows into the third flow channel from the outlet hole 231 of the drain pipe 230, and finally flows out from the second guide member 220 and slowly enters the water heater.
[0054] Thus, by setting the first guide component 210, the second guide component 220 and the drain pipe 230, the water flow from the outlet end 120 of the inlet pipe 100 can be buffered before flowing into the inner tank of the water heater. This reduces the impact on the water layer of the inner tank 10 of the electric water heater when water enters through the inlet pipe 100, protects the water layer distribution of the inner tank 10 of the water heater, and effectively improves the hot water output rate of the water heater.
[0055] In some possible implementations, the flow guiding assembly 200 further includes a scale inhibitor 250 and a scale inhibitor cap 260. The second flow guiding member 220 is provided with a first receiving groove 221, the scale inhibitor 250 is located in the first receiving groove 221, and the scale inhibitor cap 260 is located at the top of the second flow guiding member 220 and is detachably connected to the second flow guiding 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 easily precipitated and form hard limescale, which reduces the heating efficiency of the water heater.
[0057] By providing scale inhibitor 250 in the second flow guide 220, the formation of scale (mineral deposits) on the inner tank can be prevented or reduced.
[0058] In addition, by providing the scale inhibitor cap 260, the scale inhibitor 250 stored inside the second flow guide 220 can be prevented from overflowing.
[0059] In addition, the scale inhibitor cap 260 is detachably connected to the second flow guide 220 and the fixing member 240, which facilitates the assembly and replacement of the scale inhibitor cap 260.
[0060] In some possible implementations, the scale inhibitor cover 260 is provided with a mounting hole 263, and the second connecting end 242 of the fixing member 240 is provided with a limiting part 2421. The second connecting end 242 passes through the mounting hole 263, and the limiting part 2421 abuts against the scale inhibitor cover 260. In this way, the stability of the connection between the scale inhibitor cover 260 and the fixing member 240 can be improved.
[0061] In some possible implementations, the second flow guide 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 latch 2221 and an abutment 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 220, the latch 2221 is embedded in the locking groove 261, and the scale inhibitor cover 260 abuts against the abutment portion 2222.
[0062] In some possible implementations, the latch 2221 is provided with a guide ramp 21, through which the first locking structure 222 can push the scale inhibitor cap 260 to move radially along the second guide member 220.
[0063] Thus, by providing a guide slope 21 on the latch 2221, the scale inhibitor cover 260 can be guided to move radially along the second flow guide 220, so that the scale inhibitor cover 260 can be automatically aligned and inserted when it touches the guide slope 21 of the second flow guide 220, reducing the error of human alignment and improving the convenience of assembling the scale inhibitor cover 260.
[0064] In some possible implementations, the scale inhibitor cap 260 is provided with a water permeable hole 262, which is located close to the scale inhibitor 250.
[0065] In this way, the water in the water storage chamber 12 of the inner tank 10 of the water heater can fully contact the scale inhibitor 250 in the second guide member 220 through the water permeable hole 262 of the scale inhibitor cover 260.
[0066] In some possible implementations, the scale inhibitor cap 260 may be provided with a limiting hole 264, and the second flow guide 220 may be provided with a limiting post 226. The limiting post 226 has a protrusion 2261. When the scale inhibitor cap 260 is connected to the second flow guide 220, the protrusion 2261 abuts against the scale inhibitor cap 260. In this way, the cooperation between the limiting hole 264 and the limiting post 226 can improve the stability of the connection between the scale inhibitor cap 260 and the second flow guide 220, and prevent the scale inhibitor cap 260 from loosening or shifting due to vibration or other external forces.
[0067] In some possible implementations, the second flow guide 220 may be provided with a first threaded portion 227, and the scale inhibitor cap 260 may be provided with a second threaded portion 265. In this way, the scale inhibitor cap 260 can be threadedly connected to the second flow guide 220 through the first threaded portion 227 and the second threaded portion 265, thereby further improving the stability of the connection between the scale inhibitor cap 260 and the second flow guide 220.
[0068] The first threaded portion 227 and the second threaded portion 265 can be threaded holes.
[0069] In some possible implementations, the second guide member 220 is provided with a through hole 223 and a plurality of guide portions, the plurality of guide portions being disposed in the second receiving groove 228 and arranged at circumferential intervals along the through hole 223.
[0070] In some possible implementations, the flow guide includes a plurality of first flow guides 224 and a plurality of second flow guides 225. The plurality of first flow guides are close to the through hole 223 and are arranged at intervals along the circumference of the through hole 223. The second flow guides 225 are arranged at intervals away from the through hole 223. The arc length of the first flow guide 224 is smaller than the arc length of the second flow guide 225.
[0071] In some possible implementations, the flow guide is arranged in an arc shape, and the flow guide includes a concave surface 22, an 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 flow guide 220, and the convex surface 23 is disposed toward the through hole 223.
[0072] Because the convex surface 23 has a large radius of curvature, it can more effectively disperse the impact force of the water flow. When a high-speed water flow impacts 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.
[0073] Furthermore, by setting the outer convex surface 23 toward the through hole 223, water can flow out of the mounting hole 263 of the second guide member 220 and flow to the first guide section 224, and then diffuse through the first guide section 224 to the second guide section 225.
[0074] In addition, by setting the reinforcing ribs 24, the overall rigidity and deformation resistance of the guide section can be improved.
[0075] By making the arc length of the first guide section 224 smaller than the arc length of the second guide section 225, the water flow can be quickly guided to be evenly dispersed, preventing the water flow from concentrating in a certain area. That is, the arc length of the first guide section 224 is relatively short, which allows the water flow to be dispersed in a short time.
[0076] The longer arc length of the second guide section 225 allows more water to adhere to it, thereby enhancing its flow-slowing effect.
[0077] In some possible implementations, the fastener 240 includes a fixing part 243 and a connecting part 244 connected to each other. The connecting part 244 is located at the first connecting end 241, and the fixing part 243 is located at the second connecting end 242. The connecting part 244 is provided with a protruding rib 245, and the diameter of the connecting part 244 is smaller than the diameter of the fixing part 243.
[0078] Since the water taps in the inner tank are not enamelened in some manufacturing processes, the presence of ribs 245 at the connection 244 can reduce the contact between the water taps and water, thereby delaying the corrosion of the water taps.
[0079] In addition, during the manufacturing process of the inner tank, there may be irregular small enamel particles protruding inside the water tap of the inner tank. Therefore, the diameter of the connecting part 244 is smaller than the diameter of the fixing part 243. That is, the reduction in diameter can prevent the fixing part 240 from being pushed up by the small enamel particles and causing an inward concavity, which in turn leads to a reduction in the inner diameter of the fixing part 240, making it difficult to disassemble and assemble the water inlet pipe 100.
[0080] In some possible implementations, a water inlet pipe 100 connector can be provided, which connects to the water inlet pipe 100. The water inlet pipe 100 connector can be made of insulating material, preferably hydrophilic insulating materials such as PPR, PA, and PP. It can have a return water flow channel inside. The water inlet pipe 100 connector can include an internal threaded connector 101 and an external threaded connector 102. The internal threaded connector 101 can be threadedly connected to the water inlet 11 of the inner tank.
