Detailed description of the invention
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of device of built-in injection washing assisant, comprise Venturi tube 4 and washing assisant container 9, particularly, at washing machine internal, Venturi tube 4 is set, Venturi tube 4 one end is connected with water box 2 by the second water injection conduit 3, and the other end of Venturi tube 4 is connected with washing machine second water intaking valve 8; Be provided with Venturi tube joint 11 in " throat " of Venturi tube 4, washing assisant container 9 is connected with Venturi tube 4 with Venturi tube joint 11 by tube connector 10, and washing assisant container 9 is provided with liquid level alarm device.
During use, be connected by washing machine first water intaking valve 1 by the first water inlet pipe 5 with tap outlet, the second water intaking valve 8 is connected with tap outlet by the second water inlet pipe 7, liquid level alarm device detects washing assisant amount, when washing assisant amount is inadequate, and filling washing assisant, washing assisant amount is enough, start washing machine, computer board is selected " automatically adding ", washing machine enters water filling program, computer board controls the first water intaking valve 1 advanced person water a little while, such as 3 to 5 seconds, then the second water intaking valve 8 is opened, current pass through Venturi tube, produce " negative pressure " in Venturi tube joint and suck washing assisant, washing assisant enters washing machine along current, the computer board of washing machine is by programme-control second water intaking valve 8 working time, when washing assisant amount reaches appointment consumption, second water intaking valve 8 is closed, stop injecting current and liquid washing assisant by the second water intaking valve 8, when inflow reaches washing machine appointment water level, the computer board of washing machine is closed by programme-control first water intaking valve 1, and washing machine starts washing.
When not needing automatically to add washing injecting, as long as sealed by Venturi tube joint 11 sealing nut 12, neither needing dismounting, also not affecting washing machine outward appearance.
Washing machine first water intaking valve refers to washing machine electromagnetic valve, washing machine inflow electromagnetic valve is generally pilot valve, the present invention is directed to the operation principle of pilot valve and propose technical scheme of the present invention in conjunction with goal of the invention, in order to the technical scheme of the present invention of understanding clearly, simply introduce the operation principle of pilot valve below, shown in Fig. 4, Fig. 5.When water intaking valve no power, iron core is under the elastic force effect of spring, withstand on downwards on rubber valve, seal the centre bore of rubber valve, if at this moment connected at water source, water is introduced into A chamber, B chamber is entered subsequently by the aperture on rubber valve, at this moment A, B chamber is all full of water, applies certain hydraulic pressure to rubber valve simultaneously.Now, rubber valve seals the path of A chamber to C chamber, and washing machine is not intake.When entering water electromagnetic valve is energized, the iron core of entering water electromagnetic valve can under the effect of electromagnetic force, the pressure overcoming spring moves upward, centre bore on such rubber valve is opened, water in B chamber flows into C chamber by centre bore, the path entering B chamber due to current in A chamber only has the aperture on rubber membrane, flow velocity is very slow, therefore the pressure in B chamber reduces rapidly, hydraulic pressure in A chamber will soon more than the hydraulic pressure in B chamber, rubber valve is backed down, as shown in Figure 5, the water entered in A chamber flows directly into C chamber, washing machine starts water inlet, the present invention is when injecting liquid washing assisant, remain first water flowing, therefore liquid washing assisant can not pollute damage electromagnetic valve.
Be more than one of embodiment of the present utility model, for those skilled in the art, do not spend performing creative labour, multiple change can be done in the basis of above-described embodiment, can the purpose of this utility model be realized equally.But this change obviously should in the protection domain of claims of the present utility model.
