Abstract

The invention discloses a sectional water feeding type solar water heater. A water storage tank (1) is connected with two water outlets, one water outlet is positioned in the top end of the water storage tank and connected with a water return pipe (4) through a pipeline, and a water outlet valve SV1 is arranged on the pipeline of the water outlet; the other water outlet is positioned in the middleof the water storage tank and connected with the water return pipe through a pipeline, and a water outlet valve SV2 is arranged on the pipeline of the water outlet; water of the water return pipe flows to a water bucket (2), and the top end of the water bucket is connected with a movable arm (5) used for controlling a travel switch SQ to be switched on and switched off; and the solar water heaterfurther comprises a thermistor Rt1, a photoresistor Rs1 and a peripheral circuit, wherein the thermistor Rt1 is mounted in the water storage tank and used for sensing the water temperature, the photoresistor Rs1 is used for sensing the illumination intensity, and the peripheral circuit is connected with the thermistor Rt1, the photoresistor Rs1, the water outlet valve SV1, the water outlet valveSV2, a water inlet valve SV3 and the travel switch SQ. According to the solar water heater, the water feeding level can be automatically selected according to the illumination intensity of sunlight and the water temperature condition.

Description

technical field

[0001] The invention relates to a solar water heater, in particular to a solar water heater with water supply in sections, and belongs to the technical field of tap water supply. Background technique

[0002] Solar water heater is a device that uses sunlight to heat water temperature. The conversion of solar energy into heat energy mainly relies on vacuum heat collectors. Using the principle of hot water floating and cold water sinking, the water can be micro-circulated to achieve the required hot water, saving energy and environmental protection.

[0003] Now many families have installed solar water heaters, but the water storage tanks of many solar water heaters use float balls to control the water level of the water tank, but such water storage tanks often maintain the full water level, and the entire water storage tank is filled with water, which makes spring, When there is insufficient sunlight in autumn or winter, the water temperature cannot rise to th...

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] like figure 1 As shown, a segmented solar water heater includes an upper water pipe 3 connected to a faucet. One water outlet is located at the top of the water storage tank 1 and connected to the return pipe 4 through a pipeline, and an outlet valve SV1 is set on the pipeline, and the other water outlet is located at the middle of the water storage tank 1 and connected to the return pipe through a pipeline 4. Set the water outlet valve SV2 on its pipeline, the water from the return pipe 4 flows to the bucket 2, and the top of the bucket 2 is connected to the boom 5 used to control the closing and disconnection of the travel switch SQ, and also includes the water tank 1 for installation Thermistor Rt1 for sensing water temperature, photoresistor Rs1 for sensing light intensity, and peripheral circuits connected with thermistor Rt1, photoresistor Rs1, water outlet va...
