Water storage type water heater

Abstract

The invention relates to a water storage type water heater. The water storage type water heater comprises a shell, a heat preservation layer, an inner container, a water inlet pipe, a water outlet pipe and a heating rod, a lifting plate is arranged right above the water inlet pipe, a reset spring is arranged on each of the two sides of the water inlet pipe, the upper ends of the reset springs areconnected with the bottom surface of the lifting plate, the other ends of the reset springs are connected to the inner container, a sliding groove is formed in the upper surface of the lifting plate,two sliding blocks are arranged on the sliding groove in a sliding mode, the sliding blocks are connected with the portions, close to one sides of the sliding blocks, of the inner wall of the slidinggroove through springs, the sliding blocks are provide with cylindrical cleaning rods in the direction facing the heating rod, and the cleaning rods are connected with the sliding blocks through bearings directly. According to the water storage type water heater, the situation that the heating rod is corroded by water scale can be prevented, then the service life of the heating rod is prolonged, the heat conduction efficiency between the heating rod and the water is improved, and the situation that cold water directly rushes into the upper end part of the inner container, and then the temperature of hot water is influenced also can be prevented.

Description

technical field [0001] The invention relates to a water storage type water heater. Background technique [0002] When a new water heater is first used, there is no scale attached to the surface of the heating rod, and the heating rod can quickly transfer heat to the water. However, after a period of use of the water heater, scale is attached to the surface of the heating rod, and the heat of the heating rod cannot be conducted as quickly as possible. Water supply affects the heating efficiency of water, and the temperature of the heating rod itself will increase higher than before, resulting in waste of energy, and will also affect the service life of the heating rod and electric water heater, and the probability of accidents will also increase. Contents of the invention [0003] The object of the present invention is to provide a storage water heater in order to overcome the disadvantages of the prior art. [0004] In order to achieve the purpose of the invention, the te...
