Abstract

The invention provides a multifunctional anti-electric-shock water heater. The water heater comprises a shell, a liner, a heat preservation layer, an insulated water inlet pipe and an insulated wateroutlet pipe and is characterized in that the portions, corresponding to each other, of the bottoms of the shell and the liner are provided with two through holes shared by water inlet and outlet pathsrespectively, the heat preservation layer is provided with a water inlet and outlet channel, a vertical composite pipe formed by the water inlet pipe and the water outlet pipe is arranged in the water inlet and outlet channel, the water outlet pipe in the vertical composite pipe extends upwards into the liner, and a water outlet of the upper end of the water inlet pipe in the vertical composite pipe is located on the bottom in the liner. The lower end of the vertical composite pipe is connected with a horizontal water inlet and outlet pipe, and the two ends of the horizontal water inlet and outlet pipe are connected with a water outlet port and a water inlet port respectively. An anti-electric-shock connector is arranged in the horizontal water inlet and outlet pipe, and insulation watercolumns in the vertical composite pipe and the horizontal water inlet and outlet pipe can lower voltage transmitted to the anti-electric-shock connector to the safety voltage or below. A user of the water heater can be protected when other electric appliances leak electricity, and the problem that a ground wire is electrified when the electric water heater leaks electricity can also be solved.

Description

technical field

[0001] The invention belongs to the technical field of electric water heater manufacturing, and relates to the improvement of an electric shock prevention structure, in particular to a multifunctional electric shock prevention water heater. Background technique

[0002] In the current electric water heater industry, in order to prevent electric water heaters from leaking or ground wires from causing harm to water heater users, there have been a number of patent applications for electric water heaters with "anti-electric wall structures". Leakage protection for water in and out. The anti-shock principle of the existing "anti-electric wall structure" technology is: through a certain length of isolated water column (the length of the isolated water column is greater than 53 times the square of the inner hole radius) to form a water resistance with a larger resistance value, using the principle of resistance voltage division, Reduce the leakage voltage below the...
