Normal-pressure water storage water heater

Abstract

The invention discloses a normal-pressure water storage water heater which comprises a heat preservation water tank; the heat preservation water tank is internally provided with a heating element and a water level controller; the heat preservation water tank is provided with a temperature controller, a water inlet pipe and a water outlet pipe; one end of the water inlet pipe is connected with a tap water pipe, and the other end of the water inlet pipe is connected with a water inlet of the water level controller; the water outlet end of the water outlet pipe is connected with unidirectional check valves with consistent water outlet direction and a supercharging water pump in series and is also communicated with a pressure stabilizing water tank provided with a water pressure switch, a water valve, a shower head and the like. According to the invention, the using effect of a normal-pressure heat preservation water tank water heater with low manufacturing cost, which is equal to that of a pressure bearing heat preservation water heater with high manufacturing cost, can be realized, meanwhile, the water leakage generation ratio of the water temperature water tank is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of water heater manufacturing, in particular to a water storage type water heater including an insulated water tank or an insulated water tank (hereinafter, the insulated water tank or the insulated water tank is collectively referred to as the insulated water tank in the present invention). Background technique [0002] Existing water heaters can be roughly divided into instant water heaters and storage-type water heaters with insulated water tanks. Two types of water heaters. The water storage type water heater of the pressure-bearing insulated water tank, the insulated water tank is directly connected with the water inlet pipe of the tap water. The water outlet of this water heater can obtain the water outlet pressure which is basically the same as the tap water pressure, which is convenient to supply water to the higher water outlet. It can also meet the water outlet pressure required by the bathroom s...

AI Technical Summary

Problems solved by technology

The water storage type water heater of the pressure-bearing insulated water tank, the insulated water tank is directly connected with the water inlet pipe of the tap water. The water outlet of this water heater can obtain the water outlet pressure basically the same as the tap water pressure, which is convenient for water supply to the higher water outlet. It can also meet the water outlet pressure required by the shower in the bathroom. However, in order to withstand the pressure of the water and the pressure of the tap water, the structural strength of the pressure-bearing thermal insulation water tank requires high thickness and strength performance requirements of the constituent materials, so the manufacturing cost is correspondingly lower. At the same time, because the insulation water tank is always under pressure, when any part of the insulation water tank cannot withstand the water pressure, there will be water leakage, which may cause adjacent rooms to be flooded, causing unnecessary losses
