Directly-heated type solar water heater

Abstract

The invention relates to a directly-heated type solar water heater which has a structure that a water storage tank body is arranged on a base; a water inlet pipe, a water outlet pipe, an overflow pipe and an exhaust pipe are arranged on the water storage tank body; a water inlet valve is arranged on the water inlet pipe, and a water outlet valve is arranged on the water outlet pipe; the upper part of the water storage tank body is provided with a heat absorption bottom plate; the heat absorption bottom plate is in contact with the water surface of the water storage tank body; the edge of the upper surface of the heat absorption bottom plate is provided with a heat absorption side plate of which the head and the tail are connected to form a cylinder shape; the upper surface of the heat absorption bottom plate in the inner hole position of the cylinder-shaped heat absorption side plate is provided with a honeycomb heat-absorbing body; a vacuum glass cover plate is covered on the edge of the top end of the heat absorption side plate, and the water storage tank body is arranged in an inclined way; and an integral thermal insulation layer is installed on the outer wall surfaces of the water storage tank body and the heat absorption side plate. The invention has the advantages of simple and stable structure, convenient manufacture, installation and maintenance, low cost, large heat absorption area, favorable heat absorption effect, no dead angle, and the like, thereby being quite suitable for installation and use in a common household.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a direct heating solar water heater. Background technique [0002] At present, with the increasing shortage of mineral energy and the continuous improvement of people's awareness of environmental protection, solar water heaters have entered the homes of more and more residents, and have become auxiliary supply devices for domestic hot water. However, because the current solar water heaters are made of vacuum heat collecting tubes, most of the vacuum heat collecting tubes rely on imports, and the manufacturing process of the vacuum heat collecting tubes is relatively complicated, which leads to the high price of the vacuum heat collecting tubes, which makes the general price of solar water heaters relatively high, and many residents cannot Bear, inhibit the promotion of solar water heaters. Contents of the invention [0003] The purpose of the present invention is to overcome the deficie...
