Constant temperature water heater

Abstract

Thermostatic water blender in shape of framework composed of two pieces of composite insulating tube and elbow, tee joint and thermo valve is connected to water inlet and water outlet on main body of water heater. The thermo valve is positioned at a framework composed of two pieces of composite insulating tube and tee joint for hot water. Hot water pipe or cold water pipe in the composite insulating tube is composition piece of coil pipe and dual waterway pipe. The compact structure reduces space needed, lowers cost and provides good appearance. An attemperator is added to the water blender. Thus, temperature of water is adjustable so as to meet users' requirement for adjusting fine difference of temperature in range of specific temperature.

Description

technical field [0001] The invention relates to a water heater, in particular to a constant temperature water heater. Background technique [0002] There is a common problem in the water heaters currently on the market, that is, the user controls the outlet water temperature by adjusting the water mixing valve when in use, and the outlet water temperature will fluctuate due to changes in water pressure, making people feel fluctuating. It is hot, and accidents of hot water injury sometimes occur. In order to solve this problem, a Chinese patent CN2600761Y titled "Constant Temperature Water Heater" provides a water heater with a constant outlet water temperature, which mainly improves the water mixing valve connected to the bottom of the existing water heater. In this way, the temperature of the outlet water will be prevented from fluctuating due to the change of water pressure. At the same time, an insulating pipe is connected to the inlet and outlet pipes of the electric wa...

Problems solved by technology

[0004] Although this patent solves the problems of water temperature stability and leakage current, in order to meet the length requirements of the insulating pipe, the thermostatic valve is installed outside the "back"-shaped insulating pipe body frame formed by the cold and hot water insulating pipes. like figure 1 shown

Such a structure makes the structure of the constant temperature insulation device occupy a large space and the structure is not compact. When the insulating tube is added with a decorative cover, more materials are used, which increases the cost of the product and is also very unsightly; Different needs to adjust the outlet water temperature
