Description

The washing machine automatic water saving device

(1) technical field

The utility model relates to waste water and recycles the field.Being applicable to the washing machine manufacturing industry, specifically, is a kind of washing machine automatic water saving device.

(2) background technology

The earth that current mankind is depended on for existence is faced with the harm of water resource exhaustion, China particularly, populous, the water source is rare, and " using water wisely " is not slogan, but state basic policy, various for this reason water saving fixtures, particularly the waste water recycle device arises at the historic moment, for example abroad with some city of China, the grey water system of the existing unified Treating Municipal Sewage in residential quarter, but disposal cost costliness.China national practical new-type patent: 01200830.3 " family expenses automatic water saving device " begun to use, facts have proved than the economic manyfold of sub-district grey water system.But along with the deep development of country's water saving cause, the cylinder body of " family expenses automatic water saving device " automatic water-saving barrel section and washing machine can be merged, thereby reduce external automatic water-saving barrel section, improve family's plane utilization rate, reduce the domestic water saving cost.

(3) summary of the invention

The utility model main purpose increases the washing machine function, and the washing machine automatic water saving device of a kind of design and installation in washing machine inside is provided.

The purpose of this utility model is to be achieved by following technical proposals:

The photoelectricity automatic identification device is installed in washing machine cylinder body gutter both sides, and gutter connects above the filtration beds of the start and stop switch pump of water level control and non-maintaining strainer; The other end is connected to draining valve above the non-maintaining strainer filtration beds; Above the non-maintaining filtration beds rotating vane is arranged, the rotational automatic slag thing that washes away of energy when draining; Connect non retern valve below the non-maintaining strainer filtration beds, the water after the filtration can not refluxed; Non retern valve connects the underlying pump intake; The underlying pump outlet connects water storage by upper hose and wraps the mouth of a river, and the mouth of a river connects the water-closet tank bottom by sewer pipe under the water storage bag, injects the water-closet tank flush toilet automatically; Water storage has been wrapped the exhaustion spill pipe, and the water storage bag is provided with the full water microswitch, and water completely can stop retaining automatically, and carries out draining automatically; On washing machine control panel face, functional select switch is installed, functional select switch comprise the identification of washing machine drainage PROGRAMMED AUTO, photoelectricity automatically, manual drainage, manual water storage function, reach the purpose that artificial individual character is selected water-saving function; The automatic water saving device circuit is connected with the washing machine drainage circuit, and it is integrated to realize doing washing, economize on water, and has increased the Water-Saving for Washing Machine function.

The beneficial effects of the utility model are: (1) increases the Water-Saving for Washing Machine function, can be automatically and manually select the draining and the retaining of washing and washings, family's using water wisely in a large number automatically; (2) easy to install, reduce the domestic water saving investment, reduce domestic water saving and use floor area.

(4) description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is circuit theory diagrams of the present utility model.

(5) specific embodiment

Be further described below in conjunction with 1 pair of the utility model water-saving system of accompanying drawing.

As shown in Figure 1, the utility model is installed in the washing machine bottom by water pump 17, the photoelectricity identifier 15 of a pair of infrared light emission and receiving tube is installed in gutter 12 both sides of washing machine cylinder body 11, and delivery port 12 is connected to above non-maintaining strainer 13 filtration bedss and connects the start and stop switch pump 18 of water level control; Connecting non retern valve 16 below non-maintaining strainer 13 filtration bedss can not reflux the water after the filtration; The other end water valve 14 that runs in above non-maintaining strainer 13 filtration bedss, there is rotating vane when draining, to rely on the rotational automatic slag thing that washes away of current energy above the filtration beds, non retern valve 16 connects water pump 17 water inlets, water pump 17 delivery ports were connected upper hose 21 and were connected water storage bag 23 filling pipe ends, water storage bag 23 has exhaustion spill pipe 22, and the logical sewer pipe 25 in 23 times mouths of a river of water storage bag connects the automatic water filling flush toilet 33 in water-closet tank 31 bottoms and forms water-saving system; PROGRAMMED AUTO, photoelectricity are installed automatically, setting pressure switch 24 is formed the automatic water saving device Circuits System that increases on manual drainage and retaining selector switch 19, the water storage bag 23 on the washing machine; Running water pipe 32 inserts as standby from Water tank for urinal top, and washing machine sewage enters Odour seal 35 by draining valve 14, and sewer pipe 25 is connected to water tap 26, does other washing and use in sewage reservoir 34.

2 pairs of the utility model circuit are further described in conjunction with the accompanying drawings.When PROGRAMMED AUTO SD-1, the automatic SD-2 of photoelectricity, manual drainage SD-3 and retaining SD-4 selector switch SD, selector switch SD being installed on the washing machine placing a retaining SD-1 automatic program control, be that SD-1-1 disconnection, SD-1-2 connect control circuit of the washing machine in the circuit diagram 1, contact 5,6 loop works are opened draining valve 8 during the washing draining, and underlying water pump 9 does not start; Once, draining valve 8 is failure to actuate during secondary rinsing draining, contact 6,7 loop works underlying water pumps 9 start.When selector switch SD places the closed photoelectricity of two retaining SD-2 to discern automatically, the SD-1-1 closure, SD-1-2 disconnects, during washing machine drainage, washing
