Abstract

The invention relates to a non-pressure bearing operation wall mounting type solar water heater hot water supply pressurization control device. The technical points of the device are that an increasing pump which is arranged on a hot water supply and water supplementing pipe is utilized; when using hot water, an infrared sensor sends signals into a controller regulator, and then the controller regulator gives out commands to start the increasing pump to work. The beneficial effect of the device is that a heat storage water tank operates in the non-pressure bearing status; the service life of the heat storage water tank is greatly prolonged; and the manufacture cost is greatly reduced; in addition, the device has the function of leading cool water in the hot water supply and water supplementing pipe to automatically cycle to the heat storage water tank and solves the waste phenomenon that before using hot water, the cool water in the hot water supply and water supplementing pipe is firstly let out.

Description

The wall mounting type solar water heater hot water supply pressurization control device of non-pressure bearing operation

Technical field

The present invention relates to a kind of wall mounting type solar water heater hot water supply pressurization control device of non-pressure bearing operation, be applicable to split and integral wall hanging type solar water heater.

Background technology

Wall-hanging solar water heater commonly used at present includes heat storage water tank, solar thermal collector, is positioned at parts such as the heat exchanger of heat storage water tank, heat supply water pipe, filling pipe; The two ends of heat exchanger are connected with solar thermal collector.Its course of work is as follows: the medium in the heat exchanger is heated by solar thermal collector, carry out heat exchange by the running water in heat exchanger and the heat storage water tank then, running water in the storage tank is heated, when using hot water, need to adopt top water mode to move, promptly make running water enter heat storage water tank, utilize the pressure of running water to make the hot water that flows out in the heat supply water pipe that pressure be arranged, do not have pressure and can't use otherwise go out hot water by filling pipe.The shortcoming of above-mentioned wall-hanging solar water heater is that heat storage water tank is a press-bearing water tank, because of the difference variation of every day bigger, the press-bearing water tank and the welding position thereof that make of metal material expand with heat and contract with cold because of difference variation produces, thereby the generation fatigue effect, the fatigue effect of described metal material and welding position is limited, as surpassing its limit, press-bearing water tank will leak, in case leak when not reaching design service life, a whole set of water heater will subscription rate, causes unnecessary economic loss.

The invention has the beneficial effects as follows to make heat storage water tank, prolonged the service life of heat storage water tank greatly in not artesian condition work; And significantly reduced manufacturing cost; In addition, it also has makes hold concurrently cold water in the filling pipe of heat supply water be circulated to function in the heat storage water tank automatically, has solved and bleed off the heat supply water wasting phenomenon of cold water in the filling pipe of holding concurrently earlier before with hot water.

Description of drawings

Fig. 1 is structural representation of the present invention (automatic controller and infrared sensor, remote controller in the drawings do not draw).

The specific embodiment

By embodiment shown in Figure 1 as can be known, it includes heat storage water tank 4, solar thermal collector 1; It is characterized in that it also includes heat supply water hold concurrently filling pipe 13, return pipe 6, the water flow switch 12 (for commercially available prod) that is output as pulse signal, booster pump 11, first magnetic valve 5, second magnetic valve 8, pressure limiting valve 7 (its effect is the pressure that reduces running water, and protection increases the safety of pump and whole device), automatic controller, heat supply water valve 9, infrared sensor, remote controller; Described solar thermal collector 1 is connected with heat storage water tank 4 by heat collector feed pipe 2 and heat collector return pipe 3; A hold concurrently end of filling pipe 13 of described heat supply water is connected with heat storage water tank 4, its other end is connected with running water pipe, on described heat supply water is held concurrently filling pipe 13, described second magnetic valve 8, pressure limiting valve 7, booster pump 11, water flow switch 12 are housed successively from an end that is connected with running water pipe; Holding concurrently filling pipe 13 with the heat supply water between the pressure limiting valve 7 on, described booster pump 11 is connected with the heat supply water pipe 10 that heat supply water valve 9 is housed by threeway; Described booster pump 11 is held concurrently filling pipe 13 with the heat supply water between the pressure limiting valve 7 on by threeway with described first magnetic valve 5 be housed be connected with return pipe 6, described return pipe 6 stretches into the tip position place in the heat storage water tank 4; The directional bearing of described infrared sensor be with the dead ahead of hot water point or directly over; The input of described automatic controller is connected by the output of lead with infrared sensor, water flow switch 12 respectively; The output of described automatic controller is controlled the break-make of the power supply of described first magnetic valve 5, second magnetic valve 8, booster pump 11 respectively; Described remote controller and the receiver radio communication that is contained in the automatic controller.

The course of work of present embodiment is as follows:

1, be used for the split wall-hanging solar water heater:

At first open heat supply water valve 9, after flowing out low amounts of water, turn off heat supply water valve 9 at once, this moment, water flow switch 12 output arteries and veins signals were given automatic controller, automatic controller sends instruction respectively makes the booster pump 11 and first magnetic valve 5 start 1 minute simultaneously, the cold water that heat supply water is held concurrently in the filling pipe is circulated in the heat storage water tank, booster pump 11 enters the preparation work state then, in the time period of setting, when human body stands in hot water point place, infrared sensor sends signal and gives automatic controller, at this moment automatic controller sends instructions and starts booster pump 11 work, is the hot water supercharging in the heat supply water pipe 10.Can use hot water, can adjust big and little (promptly regulate the size of the operating voltage that increase pump) of the water yield by the key that adds deduct on the remote controller this moment, stops after the water in the time period of setting, and automatic controller sends the work that instruction stops booster pump.

2, be used for integral wall hanging type solar water heater (both as a whole structures of solar thermal collector and heat storage water tank):

The heat supply water course of work that cold water in the filling pipe is circulated in the heat storage water tank of holding concurrently is identical with the split wall-hanging solar water heater.

Because of the delivery port installation site of whole wall hanging solar water heater heat storage water tank is lower than water nozzle, hot water can not flow out automatically, need manually press start key on the automatic controller or the start key on the remote controller during with hot water, make booster pump enter the preparation work state, in the time period of setting, human body stands in hot water point place, infrared inductor sends signal and gives automatic controller, automatic controller can start the water supercharging that booster pump is the heat supply water pipe, can use hot water, can adjust the water yield big and little by the key that adds deduct on the remote controller this moment, stops after the water that automatic controller can send the work that instruction stops booster pump in the time period of setting.
