Problems solved by technology

That is, the water storage liner and its pipeline of the electric water heater are in a sealed state. At this time, the pressure in the water storage liner of the electric water heater and its piping system is equal to the sum of the pressure of the tap water system and part of the heating pressure, but the pressure of the tap water system Usually very high, so in order to ensure safety, the existing water heater liner needs to be able to withstand high pressure, the processing of the liner needs to have a material with sufficient thickness and strength, and the normal use of the water heater does not require excessive pressure, so The material consumption of the liner and the cost of the entire water heater are relatively high, which affects the further popularization and use of electric water heaters

Embodiment Construction

[0007] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0008] The present invention includes a shell, a closed inner tank 5, an electric heater, electric control components, a water inlet 6, a water outlet 7, a water outlet valve 4, and a water mixing valve 3, and a solenoid valve is arranged between the water inlet 6 and the inner tank 5 2. Solenoid valve 2 can be of normally closed type (open only when energized) or normally open type (closed only when energized). There is a pressure relay 1 in the inner tank, and the pressure relay 1 can also be of normally closed type (when the pressure is lower than a certain value) or normally open type (the switch is disconnected when the pressure is lower than a certain value), the specific installation position of the pressure relay 1 can be any position connected to the inner tank 5, without the need to control the water level like some open systems Li...

Abstract

An electric water heater with controllable constant pressure is composed of shell, internal container, electric heater, electric controller, water inlet, water discharging valve, water mixing valve, electromagentic valve between water inlet and internal container, and pressure relay in the internal container. When the pressure in internal container reaches a predefined value, the pressure relay is actuated to close the electromagnetic valve, so disconnecting the internal container to running water. When its pressure is lowered to a predefined value, the electromagnetic valve is opened and thewater is supplied to the internal container.

Description

1. Technical field [0001] The invention is a water heater, especially an electric water heater with constant and controllable pressure. 2. Background technology [0002] With the improvement of people's living standards, electric water heaters have won the general approval of people for their elegant appearance, clean and hygienic, multi-channel water supply, and convenient use. More and more people use electric water heaters. But generally can multi-way water supply heat storage type electric water heater at present, its water storage system is not communicated with the atmosphere except being communicated with the tap water supply system because each water outlet valve is closed when non-water use state. That is, the water storage liner and its pipeline of the electric water heater are in a sealed state. At this time, the pressure in the water storage liner of the electric water heater and its piping system is equal to the sum of the pressure of the tap water system and pa...
