Energy-saving water heater

Abstract

The invention relates to an energy-saving water heater. The shell is injection-molded into an integral body and separated into a left control chamber and a right heating chamber by a partition, wherein a wiring board in the control chambers is connected with an electrothermal tube switch which is composed of upper and lower contact spring tabs and a hydraulic pressure switch; the hydraulic pressure switch is formed by inserting an elastic cup, which is provided with an expansion link and installed on the partition, into a cover with a through hole in the middle; the inner wall of the heating chamber is provided with a transverse water inlet duct; the side wall of the transverse water inlet duct is provided with a cold water outlet which is tangential to the inner wall of the heating chamber; a ceramic valve core and a handle are connected to constitute a rotatable integral body; and the ceramic valve core is formed by connecting movable and fixed chips in a sleeve, a bottom plate, a seal ring and a rotary handle. The invention has the advantages of simple and compact structure, small size, easy assembly and maintenance, and convenient and flexible operation. The electric heater isautomatically connected by using the hydraulic pressure switch, only one water inlet tube is required, the user can use the water heat without adding accessories, and cold water can become hot water within 3 seconds; no bubbles are produced in the heating chamber; and thus, the invention greatly enhances the thermal efficiency and the effluent rate and prolongs the service life of the electrothermal tube.

Description

technical field [0001] The invention relates to an electric water heater, in particular to an energy-saving water heater that is instant on and heats quickly. Background technique [0002] Existing water heaters, such as electric water heaters, gas water heaters, and solar water heaters, have large capacity, large volume, and difficult maintenance. In addition, because the installation location and the use location are not in the same place, hot water will not flow out immediately when used, and a lot of water needs to be installed. The cold water in the long section of the water pipe is let off, and a section of hot water will be left in the water pipe after use, which not only wastes water resources but also wastes energy and time. [0003] Patent No. 200520117067.X "A Fast Electric Water Faucet with Two-way Water Inlet" also provides an electric water faucet with two-way water inlet, fast electric heating, time-saving, energy-saving, water-saving and solar water heaters. ...

[0002] Existing water heaters, such as electric water heaters, gas water heaters, and solar water heaters, have large capacity, large volume, and difficult maintenance. In addition, because the installation location and the use location are not in the same place, hot water will not flow out immediately when used, and a lot of water needs to be installed. The cold water in the long section of the water pipe is released, and there will be a section of hot water in the water pipe after use, which wastes water resources, energy and time

[0003] Patent No. 200520117067.X "A Fast Electric Water Faucet with Two-way Water Inlet" also provides an electric water faucet with two-way water inlet, fast electric heating, time-saving, energy-saving, water-saving and solar water heaters. When the power is not connected, This faucet can still be used as an ordinary faucet to provide cold water, but it adopts a double water inlet structure. When using it, two cold and hot water inlet pipes need to be installed, and the cold and hot water inlet pipes need to be connected with the cold and hot water on the two-way ceramic valve core. It can only be used when the water port is connected, and its control mechanism is more complicated. There is a manual switch between the control handle and the two-way ceramic valve core. The manual switch, water pressure switch, and electric heater are connected in series. , Electromagnetic coil connection of the relay
