Solar water heater

Abstract

The invention discloses a solar water heater. The solar water heater comprises a water tank, a support and at least one heat-absorbing tube, wherein the heat-absorbing tube is communicated with the water tank; the water tank and the heat-absorbing tube are supported by the support; the solar water heater further comprises an electric heating unit which comprises a heating coil; the water tank comprises a first liner and a second liner arranged under the first liner; the second liner is communicated with the bottom of the first liner by use of a pipeline; the heating coil is arranged in the first liner; the support comprises a base and at least one frame; the water tank is supported by the base; the frame is arranged on one side of the water tank, and the bottom of the frame is fixedly connected with the base; a blind hole is formed in the frame; the closed end of the heat-absorbing tube is embedded in the blind hole slantwise and downwards, and the open end of the heat-absorbing tube is communicated with the water tank slantwise and upwards. The solar water heater is provided with two liners; the heating coil is arranged in the first liner at the top for local heating, the time of waiting for hot water is shortened, the space is saved due to the arrangement of the support and the heat-absorbing tube, and the bearing problem of the slantwise vertical end heat-absorbing tube is solved.

Description

technical field [0001] The invention relates to a solar water heater. Background technique [0002] Such as figure 1 As shown, the solar water heaters currently on the market include a water tank 01, a heat absorbing pipe 03 and a support 02. The water tank 01 communicates with the heat absorbing pipe 03, and the support 02 supports the water tank 01 and the heat absorbing pipe 03. The heat absorbing pipe 03 is generally shoe stand. The solar energy absorbed by the heat absorbing pipe 03 is converted into heat energy, and the water in the water tank 01 is heated. However, the inclined vertical heat absorbing tube takes up a lot of space, bears a lot, and puts a lot of pressure on the bracket. In addition, the water tank is a single liner with a fixed water volume: when the volume of the liner is too small, the water that can be heated is less and the solar energy cannot be fully utilized under ideal weather conditions; In an unfavorable situation, the large amount of wat...

Problems solved by technology

However, the inclined vertical heat absorbing tube takes up a lot of space, bears a lot of weight, and puts a lot of pressure on the bracket

In addition, the water tank is a single liner with a fixed water volume: when the volume of the liner is too small, the water that can be heated is less and the solar energy cannot be fully utilized under ideal weather conditions; In an unsatisfactory situation, the large amount of water will cause the temperature to rise slowly, and the water temperature will hardly reach the target temperature, making it unusable
