Abstract

The invention discloses an external automatic water feeding device of a solar water heater. The device comprises a water inlet and outlet pipe and a water feeding and draining pipe, wherein the water inlet and outlet pipe is arranged at the lower part of a water storage tank; and the water feeding and draining pipe is communicated with the water inlet and outlet pipe. The device is characterized in that the water inlet and outlet pipe is communicated with a first annular pipe; the annular pipe is simultaneously communicated with the water feeding and draining pipe and a water level control device; the other end of the water feeding and draining pipe is communicated with a second annular pipe; the second annular pipe is simultaneously communicated with a bath pipe and a tap water pipe; and control valves are arranged on the first annular pipe and the second annular pipe. The device provided by the invention can be configured with an existing solar water tank, thus not only can the failure rate be low, but also the structure is simple, and the manufacturing cost is low.

Description

technical field

[0001] The invention relates to a solar water heater, in particular to an external automatic water supply device for the solar water heater. Background technique

[0002] Solar energy is an inexhaustible source of energy. With the development of society and the advancement of science and technology, the use of solar energy has attracted more and more attention from the whole society, and solar water heaters have entered thousands of households along with the advancement of science and technology. Wanhu provides people with a healthy life. At present, the replenishment methods of solar water heaters used by people include manual replenishment, intelligent automatic replenishment, and fool-type automatic replenishment. Of course, manual replenishment is more troublesome. Currently existing intelligent or fool-type water replenishment methods generally have the defects of high failure rate, complex structure, and high production cost. Contents of the inventio...
