Embodiment Construction

[0020] Such as figure 1 , Figure 5 As shown, the water level signal acquisition device is a cylindrical device made of plastic or non-magnetic metal shell, and there are through water pipes at both ends. On the casing 1, the main vibration coil (A-B) 3 and the feedback coil (C-D) 4 are wound from top to bottom. Inside the cavity is a floating ball 2 containing iron blocks. The lower end of the device is a connecting pipe connected to the water heater tank 13. 5. This structure constitutes the whole 6 of the water level signal acquisition device.

[0021] Such as figure 2 As shown, the main vibration coil (A-B) 3 and the feedback coil (C-D) 4 on the water level signal acquisition device 6 together with the signal acquisition circuit form an inductive feedback high-frequency oscillator 102, and the circuit diagram of the inductive feedback high-frequency oscillator is as follows image 3 As shown, the output signal of the inductive feedback high-frequency oscillator 102 is ...

Abstract

The invention discloses an automatic water supplying and breaking system of a solar water heater. A water level signal acquisition device (6) of a floating ball (2) with an iron block inside is mounted on a water tank overflow pipe (14) and externally provided with a main oscillation coil (3) and a tickler coil (4). The two coils, an inductive feedback high-frequency oscillator (102), a micro-control signal processor (9), a relay (10) and an electromagnetic valve (7) are sequentially connected, and the electromagnetic valve (7) and the other electrode of the relay (10) are connected with a 220V mains supply. By the aid of the automatic water supplying and breaking system, automatic water supplying and automatic water breaking in case of water overflowing are realized. As the coils are free of contact with water, the automatic water supplying and breaking system of the solar water heater is long in service life and reliable in working, and performance of the solar water heater is effectively improved. The automatic water supplying and breaking system can be provided to manufacturing factories of the solar water heaters to be mounted on products before leaving the factories and can be mounted on used products, so that both old and new customers are facilitated. The automatic water supplying and breaking system has the advantages of simple structure, convenience in operation, high practical value and marketing prospect.

Description

technical field [0001] The invention relates to a water supply device for a solar water heater, in particular to an automatic water supply system for a solar water heater. Background technique [0002] The upper end of the existing solar water heater water tank has a water full return pipe leading to the room, and people judge that the solar water heater on the roof is filled with water according to the flow of water from the return pipe, that is, the water supply valve is closed to complete the water supply. Due to the influence of water pressure and the water shortage volume of the water tank, it is difficult to determine the water supply time. Therefore, the user cannot stay by the water outlet for a long time. Usually, after opening the water supply valve, he is busy with other housework, or even It took too long to get on the water and I forgot to close it and went out. This situation often causes a large amount of water to overflow back into the room, which wastes wat...
