Problems solved by technology

[0003] In view of the above solutions, it is necessary to provide heating pipe installation holes and anode rod installation holes on the inner tank of the water heater. Setting multiple installation holes on the inner tank not only increases the processing difficulty and cost, but also reduces the heat preservation effect of the inner tank. Water leakage is prone to occur, and the reliability of the water heater is not high

Abstract

The invention discloses a water heater, and relates to the technical field of household appliances. The water heater comprises a liner, a cover plate, an exchanging pipe and a mounting assembly, wherein an opening end is arranged at one end of the liner; the exchanging pipe is arranged in the liner, and one end of the exchanging pipe is fixed on the cover plate; the exchanging pipe comprises a pipe body and a heater arranged in the pipe body; the pipe body is insulated from the heater; the mounting assembly enables the cover plate and the opening end of the liner to be in sealed and insulatedconnection; and an external power source is electrically connected with the liner and the pipe body through the mounting assembly. According to the water heater provided by the invention, the number of mounting holes in the liner is reduced, the structure is more reasonable, and the performance of the water heater is better.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a water heater. Background technique [0002] Aiming at the inner tank corrosion problem of the water heater, there are usually two solutions in the prior art: (1) Install the anode rod in the inner tank of the water heater as the anode, the inner tank is usually made of metal as the cathode, and forms a closed loop through water as the medium , by sacrificing the anode rod itself to prevent corrosion of the inner tank; (2) install the anode rod in the inner tank of the water heater, apply an external current, so that the anode rod is electrically connected to the positive pole of the power supply, and the inner tank is electrically connected to the negative pole of the power supply, and then Water is used as the medium to form a closed circuit, and the electrochemical protection is used to prevent the corrosion of the inner tank, and the anode rod itself does not ne...
