Water heater capable of being descaled

Abstract

The invention relates to a water heater capable of being descaled. The water heater capable of being descaled comprises a support, a water storage tank, transparent pipes and heat collection pipes. Each heat collection pipe is divided into an inner layer and an outer layer. Each outer layer is a heat absorbing pipe made from a hard material. Each inner layer is a spiral pipe formed by spiraling and curling a long-strip elastic piece. The heat absorbing pipes extend into the water storage tank. The upper end of each spiral pipe is fixed to the water storage tank, and the lower end of each spiral pipe is installed on a rotary plate. Through holes are formed in the rotary plates. A scale accumulation cavity is further fixed to the lower portion of each rotary plate. A smashing rod is further arranged on the axis of each heat collection pipe. One end of each smashing rod is installed on the water storage tank, and the other end of each smashing rod is installed on the support. Smashing pins extending in the radial direction of the smashing rod are further distributed on the periphery of each smashing rod. The length of the smashing pins is smaller than the radius of the corresponding heat collection pipe. The water heater capable of being descaled is ingenious in structure and capable of being descaled completely and efficiently, and meanwhile water pipe blockage and human body harms are not caused.

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 per...

[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
