Abstract

The utility model relates to a circulating water saving washing machine, comprising an outer housing, a washing barrel arranged in the outer housing, a water storage pot arranged therebetween and a double-way water pump arranged therebetween and used for controlling the water current to flow in two directions. The utility model has the advantages of simple structure; can directly be improved on the prior washing machine with low cost. When in use, the sewage discharged at the first time of washing is generally and directly discharged through a controllable three-way valve because of much dirt; the relatively clean utilizable water discharged at the last time of washing can be used as the first washing water at the next washing and can be stored in the water storage pot in advance. Compared with the prior method, the utility model can save 25%-30% water quantity.

Description

A kind of circulating water-saving washing machine

Technical field

The utility model relates to a kind of household electrical appliance, specifically a kind of circulating water-saving washing machine that makes full use of water resource.

Background technology

Existing washing machine generally is that water inlet pipe is connected in the wash bucket, clothing wash and dehydration in each procedure all water is emitted, and no longer be used, cause the waste of resource, particularly automatic washing machine is all the more so.

The utility model content

The technical problems to be solved in the utility model provides a kind of circulating water-saving washing machine that can utilize once more the water that use in washing machine is crossed.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

A kind of circulating water-saving washing machine comprises washing machine shell and is installed on washtub in the shell, also is provided with the water storage cylinder between shell and washtub, and the two way water pump by a controllable flow two-way flow between water storage cylinder and the washtub is communicated with.

Also be connected with a controlled three-way valve between above-mentioned two way water pump and the washtub, the valve port one of controlled three-way valve is connected with washtub, and valve port two connects externally drained pipe, and valve port three is connected with two way water pump.Controlled three-way valve inside is provided with the spool of an activity, and spool is that two ends are the cylinder of spherical shape, also is provided with the back-moving spring that the electromagnetic valve and that moves to valve port two of control spool makes spool move to valve port three between spool and valve port two inwalls.

As the improvement to such scheme, above-mentioned water storage cylinder is 2 or 3 of shape unanimity, is arranged at the washtub periphery respectively, is communicated with by the communicating pipe that is positioned at water storage cylinder bottom portion between each water storage cylinder.Washing machine shell is provided with the water storage cylinder and is communicated with the gauge that is used to observe and detect water storage cylinder middle water level, and gauge is provided with the water level detection switch of a connection washing machine internal control circuit.Be provided with gap at water storage cylinder top, gap is communicated with washtub.

The utility model is simple in structure, can directly improve on existing washing machine, and cost is low.In use, because the sewage that discharge first pass washing back is dirtier, generally directly discharge by controlled three-way valve; To cleaner, the first pass slurry when can be used for next time washing then can be deposited in the water storage cylinder in advance for the utilized water of discharging after last time cleaning.In this way water than existing washing machine product mode of washing compare and can save 25～30% water yields.

Description of drawings

Accompanying drawing 1 is the utility model example structure schematic diagram; The controlled three-way valve structural representation of accompanying drawing 2 the utility model.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model structural principle is described in further detail below in conjunction with specific embodiment and accompanying drawing:

Shown in accompanying drawing 1～2, the washing machine that present embodiment disclosed comprises washing machine shell 1, is provided with washtub 2 in the shell 1, in the space between washtub 2 and shell 1 water storage cylinder 3 is installed.Water storage cylinder 3 in this programme is two, and the water storage cylinder also can be provided with one or more according to various model washing machines inner space size certainly, exemplifies no longer one by one at this.But its quantity and layout should be considered the mechanical balance of whole washing machine.

Washing machine shell 1 is provided with and is communicated with the gauge 32 that is used to observe and detect water storage cylinder 3 middle water levels with water storage cylinder 3.Gauge 32 is provided with the water level detection switch 33 of a connection washing machine internal control circuit.When the water level in the gauge 32 reaches water level detection switch 33 height, make water level detection switch 33 the two poles of the earth conductings by the charged ion in the water, be passed in the washing machine internal control circuit thereby produce signal.Also be provided with gap 34 at water storage cylinder 3 tops, gap 34 is communicated with washtub 2.Be communicated with by communicating pipe 31 between the two water storage cylinders 3.Then be communicated with between water storage cylinder 3 and the washtub 2 by controlled three-way valve 5 and the two way water pump 4 that is positioned at the bottom.Controlled three-way valve 5 has valve port 1, valve port 2 52 and valve port 3 53.Valve port 1 and washtub 2 internal communication, valve port 2 52 is communicated with externally drained pipe, and valve port 3 53 is communicated with two

way water pump

4, and 53 of two way water pumps directly are communicated with water storage cylinder 3 bottoms.Controlled three-way valve 5 inside are provided with the spool 54 of an activity, spool 54 is the cylinder of spherical shape for two ends, also is provided with the back-moving spring 55 that the electromagnetic valve 56 and that moves to valve port 2 52 of control spool 54 makes spool 54 move to valve port 3 53 between spool 54 and valve port 2 52 inwalls.

Twice water after owing to wash clothes is dirtier, generally no longer utilizes, and this moment, controlled three-way valve 5 interior spools 54 were close in the endoporus of valve port 3 53, and sewage is directly entered the controlled three-way valve 5 from valve port 1, discharged from valve port 2 52 again.After owing to wash clothes last is cleaner relatively all over rinse water, can utilize once more, automatically start electromagnetic valve 56 by the washing machine internal control circuit this moment, spool 54 is drawn close to valve port 2 52 places, and with valve port 2 52 sealings, start two way water pump 4 simultaneously, current are flowed in the water storage cylinder 3 from washtub 2.The water yield in the water storage cylinder 3 can be known from gauge 32, when the water yield reaches a certain amount of, triggers water level detection switch 33, and the washing machine internal control circuit obtains water level signal by water level detection switch 33.When the water yield surpassed water storage cylinder 3 internal capacities, unnecessary water can flow into the washtub 2 from gap 34.At this moment, the water in the water storage cylinder 3 can be used as the first pass water when washing clothes for the second time.During use, only need to open washing machine, the washing machine internal control circuit starts two way water pump 4 and electromagnetic valve 56 automatically by the signal that water level detection switch 33 detects, and the water storage in the water storage cylinder 3 is entered in the washtub 2 through two way water pump 4, controlled three-way valve 5 successively from water storage cylinder 3.

So circulation goes round and begins again, and has made full use of the water that more totally can utilize once more that produces in the laundry processes, and the utilization rate of the water resource of Ti Gaoing has been saved limited water resource greatly.
