Built-in water-supplying device for solar water heater

Abstract

This invention discloses one solar heater water supply device, which comprises water exit tube and water in tube fixed on heater water box side, wherein, the hinged water in block piston is at water in mouth connected with float sphere inside heater box; the said water in tube is fixed on top of heater water box through sealing ring; the said water in block piston is on water in tube wall or heater water box inner wall.

Description

technical field [0001] The invention relates to a solar water heater, in particular to an improvement to a water supply device of the solar water heater. Background technique [0002] The traditional solar water heater water supply device includes two pipes, a water inlet pipe and an overflow pipe. The solar water heater supplies water to the water tank by means of the water inlet pipe until water flows out from the overflow pipe to prompt people to turn off the tap to stop the water supply. During the water supply process of this water supply device, someone must take care of it, otherwise it will cause waste of water resources, and it is very inconvenient to use. [0003] For this reason, the solar water heater that can automatically supply water has occurred on the market, and its automatic water supply device is nothing more than two kinds of structural types. An automatic water supply device is an electronically controlled water supply device composed of electrical com...

Problems solved by technology

First of all, the auxiliary water tank of the automatic water supply device is connected to the atmosphere, and the water level difference between the auxiliary water tank and the main water tank of the solar water heater is very small, which inevitably causes defects such as slow water supply speed and easy fouling of the water inlet pipe wall. Even the normal water supply will directly affect the use of solar water heaters; secondly, the connection between the auxiliary water tank and the main water tank is inserted into the main water tank of the water heater through an outlet pipe on the auxiliary water tank, and the outlet pipe of the auxiliary water tank is connected to the jack of the main water tank of the water heater. The sealing between them is realized by the annular rubber ring. Due to the weight of the auxiliary water tank and the increase of the load after being filled with water, coupled with the influence of outdoor strong winds, this structure is easy to cause damage to the sealing ring and make the auxiliary water tank connected to the main water tank. Water leakage at the place; moreover, due to the existence of the auxiliary water tank, the manufacturing cost and structural complexity of the solar water heater are also increased
