Abstract

The utility model discloses an automatic water supply and water stop device for a solar water heater, which comprises a single-chip microcomputer, a power supply, a water level sensor, a keyboard, a display, an alarm, a time relay, a clock chip, an electronically controlled two-way valve and a water pipe; Connect single-chip microcomputer, time relay and electric control two-way valve; Said single-chip microcomputer connects water level sensor, keyboard, display, alarm and clock chip respectively; Said single-chip microcomputer connects time relay through photocoupler; Said time relay connects electric control two-way valve; both ends of the electronically controlled two-way valve are connected to water pipes; the utility model can pre-set the time of water supply through a simple and reasonable automatic water supply device and water stop device, and the time relay delay time is up, and the power is automatically cut off. Therefore, the electric control two-way valve is also cut off, and the valve spring resets to realize automatic water cutoff, which can avoid the occurrence of water overflow.

Description

A kind of solar water heater automatically send water and stopping device

Technical field

The utility model the utility model belongs to solar water heater field, and what be specifically related to a kind of solar water heater send water and stopping device automatically.

Background technology

The storage tank of existing solar water heater is installed on above roof mostly, by upper and lower conduit road, be connected to indoor, water on solar water heater, generally when overflow pipe water outlet, manual-lock water supply valve, during upper water, often can run into following problems: as above suddenly busyly during water go out or cut off the water, forget again and close water supply valve, at home nobody time, when sleeping soundly or seeing TV (listening to the music) sound is excessive and cause can't hear spilling water sound, all can cause water resource to be wasted in a large number, and because of the water of water tank be that cold water brings the inconvenience that needs to postpone bathing or the bathing of going out to user entirely.

Summary of the invention

The utility model is exactly for the deficiencies in the prior art, and what a kind of rational in infrastructure, the generation that can avoid spilling water phenomenon was provided send water and stopping device automatically.

The notebook automatic heat radiation frame that can dispel the heat timely and effectively, save electric energy simultaneously and be convenient to carry.

For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises single-chip microcomputer, power supply, level sensor, keyboard, display, alarm, the time relay, clock chip, automatically controlled two-port valve and water pipe; Described power supply connects respectively single-chip microcomputer, the time relay and automatically controlled two-port valve; Described single-chip microcomputer connects respectively level sensor, keyboard, display, alarm and clock chip; Described single-chip microcomputer is by photoelectrical coupler connect hours relay; The described time relay connects automatically controlled two-port valve; Described automatically controlled two-port valve two ends connecting water pipe.

Further, described time relay time delay is set by single-chip microcomputer turn-off time.

As preferably, the matrix keyboard that described keyboard is three rows and four columns; Described display is model 1602 liquid crystal displays; Described alarm is buzzer.

Further, described keyboard forms by the 10 numeric keys of upper water time, on & off switch and pressure key of cutting off the water is set.

Further, described display displaying time and water level.

The utility model beneficial effect:

The utility model, by automatic water-supply apparatus and the stopping device of advantages of simple, can preset the time of water, and time relay delay time arrives, auto-breaking, thereby the also power-off of automatically controlled two-port valve, valve spring resets and realizes automatic shutoff, can avoid spilling water phenomenon to occur.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

1-single-chip microcomputer; 2-power supply; 3-level sensor; 4-keyboard; 5-photoelectrical coupler; The 6-time relay; The automatically controlled two-port valve of 7-; 8-water pipe; 9-display; 10-alarm; 11-clock chip.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described, following each described only for the specific embodiment of the present utility model is described, to the not restriction of the utility model protection domain.

As shown in drawings, the utility model comprises single-chip microcomputer 1, power supply 2, level sensor 3, keyboard 4, display 9, alarm 10, the time relay 6, clock chip 11, automatically controlled two-port valve 7 and water pipe 8; Described power supply 2 connects respectively single-chip microcomputer 1, the time relay 6 and automatically controlled two-port valve 7; Described single-chip microcomputer 1 connects respectively level sensor 3, keyboard 4, display 9, alarm 10 and clock chip 11; Described single-chip microcomputer 1 is by 5 connect hours of photoelectrical coupler relay 6; The described time relay 6 connects automatically controlled two-port valve 7; The time relay 6 delay times arrive, auto-breaking, and the also power-off of automatically controlled two-port valve 7, described automatically controlled two-port valve 7 two ends connecting water pipes 8, thus stop upper water.

The described time relay 6 time delays are set by single-chip microcomputer 1 turn-off time, single-chip microcomputer 1 pre-deposits the time of water in a plurality of water level correspondences, during upper water, by level sensor 3, judge current water level, the water level that current water level and single-chip microcomputer 1 are prestored is compared, determine the time of the time relay 6 delay cut-offs, when there is exsiccosis, described alarm 10 sends warning, and described alarm 10 is buzzer; The matrix keyboard that described keyboard 4 is three rows and four columns, described keyboard 4 forms by the 10 numeric keys of upper water time, on & off switch and pressure key of cutting off the water is set; Described display 9 is model 1602 liquid crystal displays, described display 9 displaying times and water level.

Above-described embodiment; it is an example of the present utility model; be not for limiting enforcement of the present utility model and extent of competence, all or technical schemes of being equal to identical with content described in the utility model claim, all should be included in the utility model protection domain.
