Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The magnetic float water level monitor for solar water heater as shown in fig. 1 and 2 comprises a measuring tube 1 which is through in the middle and is longitudinally arranged, and the lower port 11 of the measuring tube is communicated with the lower part of a water storage cylinder 91 in the solar water heater 9, thereby forming a communicating vessel structure. In order to prevent the water in the solar water heater from overflowing from the upper port 12 of the metering tube 1, the upper port of the metering tube is not lower than the overflow water level line arranged in the solar water heater, namely, the upper port 12 is not lower than the height of the overflow port 92 arranged on the water storage cylinder.

Meanwhile, a floating block 2 is arranged in the metering pipe and can float up and down along with the change of the water level in the metering pipe. A magnet 3 is fixedly provided in the slider. And the outer side of the metering tube is provided with at least two reed pipes 4 which can be magnetized by the magnet to realize conduction, and each reed pipe is connected with a control device 5 which can control the opening and closing of an upper water electromagnetic valve in the solar water heater through a lead so as to achieve the purpose of monitoring and controlling the water level in the water storage cylinder 91 in real time.

In addition to the above embodiments, the measuring tube 1 is made of stainless steel.

On the basis of the above embodiment, a fixed sleeve 6 is fixedly arranged on the outer side of the metering tube 1, the fixed sleeve is provided with a plurality of mounting holes matched with the reed pipes one by one, and the reed pipes 4 are mounted in the mounting holes in an inserting manner and are connected with the fixed sleeve in an inserting manner.

On the basis of the above-mentioned embodiment, the fixing sleeve is made of plastic, or other materials with good insulating effect can be used.

As shown in fig. 3a and 3b, in the actual use process, although the lower part of the water storage cylinder 91 is equipped with two water inlet pipes, because the manufacturers are different, the design positions of the water inlet pipes are different, some are arranged at the bottom of the water storage cylinder, and some are arranged at the lower part of the side of the water storage cylinder, because the utility model discloses can adapt to the solar water heater of various model structures, the concrete structure of the metering tube can be "L" type structure, also can be "J" structure to realize that the part used for the float to move up and down in the metering tube is in the vertical state.

The following is a detailed description of the working principle of the present invention, and the number of reed pipes is three, wherein the three reed pipes 4 are respectively set at 1, a point a equal to the overflow water level of the solar water heater, 2, a point B when 30% of the solar water heater remains, and 3, a point C when the water in the solar water heater is dry.

When tap water is supplied to the solar water heater, the water level of the solar water heater rises slowly, and the floating block 2 rises along with the water level and drives the magnet 3 in the floating block to rise together. When the solar water heater is filled with water (namely the water level reaches the set overflow water level line), the magnet rises to a point A at the same horizontal height as the reed pipe 4 at the highest position, the contact of the reed pipe at the highest position is closed under the action of the magnetic force of the magnet 3, the R2 resistor is switched on, the C pole and the E pole of the BG1 base B are electrified, the J1 relay is attracted, and the

contacts

1 and 3 are disconnected. The J2 relay loses power, so that the

J3 contacts

1 and 2 are powered off, and the water supply solenoid valve stops supplying water to the solar water continuously.

When the water level of the solar water heater is reduced to 30% in the using process, the magnet 3 descends to a point B along with the floating block 2 and is located at the same horizontal position with one of the three reed switches, at the moment, the reed switch at the position is closed under the action of the magnet 3 to switch on the C1 electrolytic capacitor and trigger the conduction of the C pole and the E pole of the BG2 transistor, so that the pin 3 of the IC time-base integrated circuit is output at a high level, the J4 relay is attracted, the

contacts

1 and 2 of the J4 relay are closed to charge the C4 electrolytic capacitor, and meanwhile, the light-emitting diode and the buzzer which are connected in parallel with the C4 motor capacitor give out sound and light prompts. At the moment, after the IC time-base integrated circuit delays for 5 minutes (the delay time can be set specifically according to specific conditions), the circuit is turned over, the 3 feet become low level, the J4 relay is released, the 1 and 2 contacts in the J4 relay are disconnected, meanwhile, the 1 and 3 contacts are attracted, the C4 electrolytic capacitor discharges, the C pole and the E pole of the BG3 collector are triggered to be conducted through the R9 resistor, the J5 relay 1 and the J5 relay 2 are closed, the J2 and the J3 relay 1 and the J3 contact are triggered to be closed, and then the power supply of a magnetic feeding valve in the solar water heater is switched on, so that water can be automatically fed into the solar water heater. (the operation of the phase can ensure that the user of the solar water heater has certain buffering time, and the situation that the water is immediately changed into cold water when the water consumption reaches 30 percent due to the instant water supply of the solar water heater is prevented).

When the solar water heater 9 uses hot water, the floating block 2 drives the magnet 3 to descend and agree with the horizontal height with the reed pipe arranged at the point C of the waterless position, at the moment, the contact of the reed pipe 4 at the point C is closed under the magnetization effect of the magnet, the relay of J2 and the relay of J3 are directly started to be sucked, at the moment, the water supply electromagnetic valve is switched on and opened, and the solar water heater realizes the automatic water supply function.
