Electrode type water heater capable of adjusting descaling powder automatically

Abstract

The invention discloses an electrode type water heater capable of adjusting descaling powder automatically. The electrode type water heater comprises an insulating shell and an insulating end cover encapsulated at one end of the insulating shell. The insulating shell is internally provided with at least one set of parallel electrode sets located at the lower half segment of the insulating shell in a spaced manner. The electrode sets are fixedly arranged on the insulating end cover through sealing pieces. The insulating shell is further internally provided with insulating pieces located at the upper half segment of the insulating shell. The top ends of the insulating pieces are connected with insulating pull rods driven by a power mechanism. The bottom end of each insulating piece extends into the spaces in each electrode set. The insulating pieces can be driven by the power mechanism to move up and down in the spaces in of the corresponding electrode set so that the circuit can be in the disconnected state or the power output state. By the adoption of the structure, dirt can be cleaned through the insulating sleeves, power can be adjusted as well, the service life is prolonged greatly, the manufacturing use cost is very low, the use requirement of people is met, and the electrode type water heater has good application and population value.

Description

technical field [0001] The invention relates to a water heater, in particular to an electrode type water heater with adjustable automatic descaling power. Background technique [0002] Traditional water heaters have heat transfer medium loss when heating water, and the power cannot be adjusted. Later, water heaters with adjustable power appeared on the market, but their structural design is very complicated, and the manufacturing and use costs are high, which is not conducive to popularization and use. Some electrode water heaters have a simple and reasonable structural design and good practicability, but they do not have the function of descaling, and once the electrode surface is scaled, the power will be greatly reduced or even invalid, resulting in a very short service life and high replacement costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electrode type water heater with adjustable power for auto...
