Embodiment 1

[0013] The solar water heater includes a main water tank 1, a heat collecting pipe 2, and a bracket 3. The main water tank 1 is provided with an exhaust overflow hole 11, and the main water tank 1 is fixed on the bracket 3. It also includes an auxiliary water tank 4, and an inlet and outlet water tank is opened on the auxiliary water tank. hole 41, the heat collecting tube 2 includes an inner tube 21 and an outer tube 23, a vacuum layer 24 is formed between the outer tube 23 and the inner tube 21, a layer of coating 22 is covered on the wall of the inner tube 21, and both ends of the heat collecting tube 2 are As an opening, one end of the heat collecting pipe 2 is connected to the inside of the main water tank 1 , and the other end is connected to the inside of the auxiliary water tank 4 .

[0014] The auxiliary water tank 4 is a cuboid with a capacity of 1 / 30 of the main water tank 1, and the water inlet and outlet 41 are opened on the wall of the auxiliary water tank 4.

Embodiment 2

[0016] The auxiliary water tank 4 is a cuboid with a capacity of 1 / 40 of the main water tank 1. The water inlet and outlet 41 are opened at the bottom of the auxiliary water tank 4, directly below the mouth of the outermost heat collecting pipe 2. Other structures are the same as in Embodiment 1.

Embodiment 3

[0018] The auxiliary water tank 4 is a cuboid with a capacity of 1 / 50 of the main water tank 1 , and the water inlet and outlet 41 are opened on the side wall of the auxiliary water tank 4 . Other structures are the same as in Embodiment 1.

Abstract

The invention relates to a water heater, in particular to a solar water heater. The solar water heater includes a main water tank, a heat collecting pipe, and a support. There is an exhaust overflow hole on the side of the main water tank. The main water tank is fixed on the support. It also includes an auxiliary water tank. A vacuum layer is formed between the tube and the outer tube, the outer tube and the inner tube, and the inner tube wall is covered with a layer of coating. Both ends of the heat collecting tube are open. to the inside of the auxiliary water tank. The double-opening and double-pass pipe design also makes the cleaning of the heat collecting pipe particularly easy, and the water inlet and outlet holes are set on the auxiliary water tank, so that the water in the water heater can be fully utilized and energy is saved.

Description

technical field [0001] The invention relates to a water heater, in particular to a solar water heater. Background technique [0002] With the continuous strengthening of people's awareness of environmental protection, more and more consumers tend to choose solar water heaters. The heat collecting tube is the core component of the solar water heater, and the existing heat collecting tubes all have one end open and one end closed, forming the shape of a U-shaped tube. First of all, tap water is prone to scale after repeated heating in the heat collecting tube of this shape, and accumulates on the closed end of the heat collecting tube, which is very difficult to clean. The capacity will become smaller and smaller, which not only affects the heating effect of the water heater, but also affects the service life of the water heater. Secondly, the water inlet and outlet of the existing solar water heaters are all arranged on the main water tank. Since the water inlet and outlet ...
