descaling water heater

Abstract

The invention relates to a descaling water heater. The descaling water heater includes a bracket, a water storage tank, a transparent tube and a heat collecting tube; the heat collecting tube is divided into two layers, the outer layer is a heat absorbing tube made of hard material, The inner layer is a helical tube formed by spirally curling long shrapnel; the heat-absorbing tube extends into the water storage tank; the upper end of the helical tube is fixed on the water storage tank, and the lower end is installed on the turntable; on the turntable A through hole is opened, and a fouling chamber is fixed below the turntable; a smashing rod is installed on the axis of the heat collecting tube, one end of the crushing rod is installed on the water storage tank, and the other end is installed on the bracket There are crushing needles extending radially along the crushing rod on the circumferential direction of the crushing rod, the length of the crushing needles is less than the radius of the heat collecting tube; Blockage of water pipes and personal injury.

Description

technical field [0001] The invention relates to a water heater, in particular to a water heater which is convenient for descaling. Background technique [0002] A water heater is a tool that provides hot water for a limited range. After years of development, water heaters are divided into the following categories: storage electric water heaters, instant electric water heaters, instant electric water heaters, gas water heaters, solar electric water heaters and air Source water heaters; among them, solar water heaters are favored by the majority of users for their advantages of environmental protection, energy saving, and convenience; traditional solar water heaters guide cold water into heat collecting tubes, and the heat collecting tubes absorb light energy and heat the cold water. The hot water is sent back to the water storage tank; during the long-term heating process, scale is easy to harden in the heat collecting tube. With the increase of scale, the heat transfer perfo...

[0002] A water heater is a tool that provides hot water for a limited range. After years of development, water heaters are divided into the following categories: storage electric water heaters, instant electric water heaters, instant electric water heaters, gas water heaters, solar electric water heaters and air Source water heaters; among them, solar water heaters are favored by the majority of users for their advantages of environmental protection, energy saving, and convenience; traditional solar water heaters guide cold water into heat collecting tubes, and the heat collecting tubes absorb light energy and heat the cold water. The hot water is sent back to the water storage tank; during the long-term heating process, scale is easy to harden in the heat collecting tube. With the increase of scale, the heat transfer performance of the heat collecting tube decreases, and the diameter of the heat collecting tube becomes smaller, which makes the heating of the water heater The descaling effect and water output speed are rapidly declining, so descaling has become one of the problems that water heaters need to solve urgently; currently, in the descaling of water heaters, drug descaling is mostly used. This method can only gradually dissolve the surface scale, and the descaling effect is slow and ineffective. Thorough, and it is easy to cause drug residues, which is harmful to the human body
