[0002] The function of the anti-electric wall is not only to block the possible leakage of the electric water heater itself, but also to block the safety threat to the shower person caused by the charged ground wire or the charged water pipe. When the electric water heater is powered on, even if the water in the heating tank has electricity, the resistance of the water itself will be attenuated under the action of the anti-electric wall, thereby achieving the purpose of electrical isolation, so that the voltage at both ends of the water inlet and outlet of the water heater reaches almost zero and an extremely weak current of less than 0.02mA / kw.

In the process of the cold water flow diffusing, it will cause a large disturbance to the water layer, causing the water temperature in the inner tank to drop rapidly, reducing the output efficiency of hot water.

[0004] Therefore, further improvement is needed. Utility Model Content

[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] First embodiment

[0027] like Figure 1-5 As shown, a water pipe for preventing electric shock and an electric water heater are provided. The water pipe for preventing electric shock includes an adapter 1 and a water pipe assembly 2 arranged on the adapter 1. The water pipe assembly 2 includes an inner tube 201 and an outer tube 202. The inner tube 201 is connected with the adapter 1 and inserted on the adapter 1. A slow flow structure 3 is sleeved on the inner tube 201. When cold water is discharged, the cold water is discharged from the outer tube 202 at a slow flow under the action of the slow flow structure 3. The slow flow structure 3 includes a slow flow sleeve 301. The slow flow sleeve 301 is provided with a guide groove 3011 for draining stains.

[0028] Specifically, the slow-flow structure 3 can effectively slow down the speed of the water flow, prevent the water from flowing in the inner tank of the electric heater, make the cold water slowly flow to the hot water area, avoid affecting the heating effect, maintain the cold and hot stratification effect in the water heater, ensure the water temperature inside the electric water heater is stable, and improve the output efficiency of hot water.

[0029] Further, if Figure 3 As shown, a slow flow space 4 is formed between the slow flow structure 3 and the outer tube 202, and a gap a of the slow flow space 4 is 0.05-2.5 mm.

[0030] Specifically, the size of the gap a is to achieve a smooth flow of cold water in the inner tank. Generally, the smaller the gap a is, the better the effect of the slow-flow structure 3 is.

[0031] It should be noted that the size of the gap a can also be adjusted according to the specific application scenario to achieve the best effect.

[0032] Preferably, the gap a is 0.05, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, or 2.5 mm.

[0033] Further, if Figure 3 As shown, the slow-flow sleeve 301 is sleeved on the inner tube 201 and is tightly connected to the inner tube 201 .

[0034] Specifically, the slow-flow sleeve 301 can be tightly connected to the inner tube 201, so that the water flow can be sufficiently decelerated when passing through the slow-flow sleeve 301, so that the water flow can be discharged more smoothly, which can improve the efficiency and energy saving of the electric water heater.

[0035] Further, if Figure 3 As shown, the length dimension c of the slow-flow sleeve 301 is 5 mm ≤ c ≤ 150 mm.

[0036] Specifically, the length size range of the slow-flow sleeve 301 can reduce the water flow velocity, thereby achieving slow water discharge.

[0037] Preferably, the length dimension c of the slow flow sleeve 301 is 5 mm, 10 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, or 150 mm.

[0038] Further, if Figure 3 As shown, the slot size b of the guide slot 3011 is 0.2 mm ≤ b ≤ 9.5 mm.

[0039] Specifically, the slot size b of the flow groove 3011 is 0.2mm to 9.5mm to ensure effective cleaning of drainage stains; if the slot size is too large, the stains may not be completely removed, affecting the drainage effect; if the slot size is too small, it may not be able to effectively prevent the accumulation of stains.

[0040] Preferably, the slot size b is 0.2 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or 9 mm.

[0041] Further, if Figure 4 and Figure 5 As shown, at least one guide groove 3011 is provided, and at least one guide groove 3011 is arranged around the slow-flow sleeve 301 .

[0042] Specifically, a guide groove 3011 can be set on the slow-flow sleeve 301; or multiple guide grooves 3011 can be set around the slow-flow sleeve 301, as long as the guide grooves 3011 can discharge stains, so as to avoid poor drainage.

[0043] Further, if Figure 5 As shown, the guide groove 3011 is in an inclined shape, a straight flow shape, an arc shape, or a snake shape.

[0044] Specifically, the shape of the guide groove 3011 can further ensure the maximization of the drainage effect.

[0045] Further, if Figure 3 As shown, the outer tube 202 is provided with a plurality of drainage holes 2021 evenly spaced apart, and the spacing distance d between the drainage holes 2021 and one end of the slow-flow sleeve 301 is 3 mm ≤ d ≤ 150 mm.

[0046] Specifically, the spacing distance d between the drainage hole 2021 and one end of the slow-flow sleeve 301 can make the water flow more evenly dispersed and flow during drainage, thereby avoiding water flow concentration or blockage.

[0047] Preferably, the spacing distance d is 3 mm, 5 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, or 150 mm.

[0048] An electric water heater comprises an outer shell and an inner tank arranged in the outer shell. The inner tank is provided with a water pipe interface, and an anti-electric wall water pipe is arranged on the water pipe interface. One end of a water pipe assembly 2 extends into the inner tank.

[0049] Second embodiment

[0050] like Figure 6 As shown, the anti-electricity wall water pipe is different from the first embodiment in that:

[0051] At least one slow-flow sleeve 301 is provided, and at least one slow-flow sleeve 301 is arranged on the inner tube 201 at a relative interval.

[0052] Specifically, one slow-flow sleeve 301 can be provided, or there can be multiple slow-flow sleeves 301. Multiple slow-flow sleeves 301 are segmentedly sleeved on the inner tube 201, which helps to slow down the water flow speed, improve the drainage stability, and improve the efficiency and energy saving of the electric water heater.
