Problems solved by technology
But the first method is difficult to realize for the fast-heating electric water heater with a small heating tank
The second method is very troublesome to install the water resistor between the inlet of the water heater and the water mixing valve
The two methods are also difficult to install for a large number of fast-heating electric water heaters already in use
Therefore, some people in the industry have invented spiral water flow channels, mosquito-repellent incense flow channels, etc., but the structure of the spiral water flow channel is too large, which is not conducive to installation.

Embodiment
[0020] Embodiment: a kind of electric water heater anti-shock protection device, such as figure 1 As shown, it includes an insulating upper cover 1, an insulating lower cover and an insulating water tank plate 2. A group of water flow guide structures is formed on the upper end surface of the insulating water tank plate. The lower end surface of the insulating water tank plate is closed to form the insulating lower cover. Sealing rings are provided on the sealing surfaces of both the insulating water tank tray and the insulating upper cover, specifically, a first silicone ring 8 is provided between the outermost waterway wall and the insulating upper cover, and the innermost waterway wall is connected to the insulating upper cover. A second silicone ring 9 is provided between the upper covers, and a third sealing ring 10 is provided between the rest of the channel wall and the insulating upper cover, which combines the traditional independent insulating sink pan and the insulat...

The invention discloses an electric-shock prevention protector of an electric water heater. Water flow guiding structures are formed on a plurality of insulation water groove plates of the electric-shock prevention protector. Runners are determined jointly by an upper insulation cover, a lower insulation cover, the insulation water groove plates and the water flow guiding structures thereon, water flows into the water flow guiding structures in the insulation water groove plates from the upper insulation cover. By the special design of the water flow guiding structures, water flow direction of the adjacent runners in the water flow guiding structures are not in the same direction but flow in opposite direction, the cross section area and the length of each runner effectively guarantee that possible leakage current contacting with users actually is lower than the national corresponding standards of electric water heaters on the condition of regulated water flow and electric conduction rate in electric leakage accidents, so that safety in use is guaranteed, and further, the insulation water groove plates and the lower insulation cover which are used to be independent are integrated, structure is simplified, sealing performance is enhanced, and product reliability is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of electric water heaters, and in particular relates to an electricity safety device for electric water heaters. Background technique [0002] At present, various types of electric water heaters use leakage switches and anti-leakage circuits, relying on the grounding of electric water heaters to solve the problem of preventing electric shock. There are potential safety hazards. If the water heater itself leaks electricity during use, and the above-mentioned problem of irregular grounding wires is added, it will be difficult to guarantee water safety. [0003] At present, some manufacturers use the water resistance method to share the leakage voltage, and increase the resistance value of the water flow by lengthening the water flow channel to meet the leakage prevention requirements and ensure that the human body is not shocked. Some have lengthened insulation inlet and outlet pipes installed in the hot wat...
