Description

A kind of washing machine intelligent water-saving tank

Technical field

The utility model relates to a kind of water-saving box, particularly a kind of washing machine intelligent water-saving tank.

Background technology

At present, the shortage of water resource has become the main restricting factor of current global social and economic development; Rational utilization of water resources; It is the task of top priority of human kind sustainable development; And using water wisely is the key point of water resources rational use; Be the most fast, the most feasible, safeguard one of approach of sustainable utilization of water resource the most effectively, Constructing Water-saved Society, be solve China's shortage of water resources problem the most at all, the most effective strategic measure.

The washing machine of being sold on the market at present all is that waste water and the clear water behind the rinsing clothes that washing machine washs behind the clothes are directly entered downcomer when work, does like this and has wasted great amount of water resources, so prior art is still perfect inadequately.

Summary of the invention

The purpose of the utility model is: provide a kind of simple in structure, safe and reliable, but the easy installation and removal using water wisely, effectively utilize a kind of washing machine intelligent water-saving tank of water resource, to overcome the deficiency of prior art.

The utility model is to be constructed as follows: a kind of washing machine intelligent water-saving tank; Comprise water-saving box; Water-saving box is provided with the water inlet pipe that is connected with washing machine sewer pipe; Water inlet pipe is provided with pH value sensor and solenoid directional control valve, and pH value sensor signal output is connected with the signal input part of single-chip microcomputer, and the signal output part of single-chip microcomputer is connected with solenoid directional control valve; The delivery port of solenoid directional control valve one end is connected with catch basin with filter through pipeline, and the delivery port of the solenoid directional control valve other end is connected with drainpipe.

Solenoid directional control valve is the two-position three way solenoid directional control valve.

Owing to adopted technique scheme; The drainpipe of washing machine is connected with the water inlet pipe of water-saving box, when behind the washing machine cleaning clothes during draining, the water body pH value sensor of flowing through; The PH numerical value that the pH value sensor will detect in the water feeds back in the single-chip microcomputer; When solenoid directional control valve did not obtain commutation signal, water body communicated with sewage effluent through solenoid directional control valve, and this moment, wash water directly entered sewer; And when pH value is lower than the predetermined parameters value; After single-chip microcomputer sends actuating signal to solenoid directional control valve, the solenoid directional control valve switching-over, water body communicates with catch basin through solenoid directional control valve; The water of discharging during washing machine rinsing at this moment just flows into catch basin, for the utilization once more in later stage; Compared with prior art, the utility model not only has advantage simple in structure, safe and reliable, but and designs ingenious, easy installation and removal using water wisely, effectively utilizes advantages such as water resource.

Description of reference numerals: 1-water-saving box, 2-water inlet pipe, 3-PH value sensor, 4-solenoid directional control valve, 5-single-chip microcomputer, 6-filter, 7-catch basin, 8-drainpipe.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.

The enforcement of the utility model: a kind of washing machine intelligent water-saving tank; As shown in Figure 1; Comprise water-saving box 1, water-saving box 1 is provided with the water inlet pipe 2 that is connected with washing machine sewer pipe, and water inlet pipe 2 is provided with pH value sensor 3 and solenoid directional control valve 4; PH value sensor 3 signal output parts are connected with the signal input part of single-chip microcomputer 5; The signal output part of single-chip microcomputer 5 is connected with solenoid directional control valve 4, and the delivery port of solenoid directional control valve 4 one ends is connected with catch basin 7 with filter 6 through pipeline, and the delivery port of solenoid directional control valve 4 other ends is connected with drainpipe 8.

Solenoid directional control valve 4 is the two-position three way solenoid directional control valve, and its Applicable media is the little liquid of gas, water and viscosity such as steam, and scope range of the fluctuation of voltage is ± 10%, and valve body material is a stainless steel.

PH value sensor 3 is a prior art products, and pH value sensor 3 can directly invade or insert in the water, its output current 4-20mA, and output voltage 10-36V, the work range is 0-14PH, and precision is 2% of a full scale, and operating temperature is-5 ℃-55 ℃.

It is that STMicroelectronics company produces that single-chip microcomputer 5 is selected a kind of in the STC series monolithic, this type single-chip microcomputer for use, and the single-chip microcomputer operating voltage is 5.5V-3.4V (a 5V single-chip microcomputer); The highest frequency clock is 80M, and the flash memory is 8k, and RAM is 512bit; Can erasable repeatedly programming; Operating temperature range is 40-80 ℃, built-in watchdog circuit, and internal electric source electric power system, clock circuit and reset circuit all pass through special treatment.

Use single-chip microcomputer 5 can realize the Based Intelligent Control of this device.

Filter 6 can filter the foreign material that enter in the catch basin 7, and catch basin 7 can be made corresponding size according to actual needs, and catch basin 7 can directly take out from water-saving box 1, and the water that then the inside is stored is poured out and utilized.

During the utility model work; At first the drainpipe with washing machine is connected with the water inlet pipe 2 of water-saving box 1; And in single-chip microcomputer 5 input predetermined parameters value (as 7.2), draining behind the washing machine cleaning clothes, the water body of the discharge pH value sensor 3 of at first flowing through; The PH numerical value that pH value sensor 3 will detect in the water feeds back in the single-chip microcomputer 5; When solenoid directional control valve 4 did not obtain commutation signal, water body communicated with sewage effluent through drainpipe 8 through solenoid directional control valve 4, and this moment, wash water directly entered sewer; And when pH value is lower than 7.2; After single-chip microcomputer 5 sends actuating signal for solenoid directional control valve 4, solenoid directional control valve 4 switching-overs, water body communicates with catch basin 7 through solenoid directional control valve 4; The water of discharging during washing machine rinsing at this moment just flows into catch basin 7, for the utilization once more in later stage.
