Description
Technical field
The utility model relates to the technical field of washing machine, especially refers to a kind of digital water level control device of washing machine.
Background technology
Existing pulsator washing machine structure and water inlet demonstration; As shown in Figure 1, comprise the impeller 1 ', interior bucket 2 ', the outer bucket 3 ' and shell 4 ' that set gradually from the inside to the outside, outer bucket 3 ' below is provided with drive unit 5 '; Impeller 1 ' all can be by drive unit 5 ' driven rotary with interior bucket 2 '; Simultaneously, the upper frame of shell 4 ' is provided with the water inlet pipe 8 ' of bringing water valve 81 ' into, and the outer setting of outer bucket 3 ' has a wireway 9 '; One end of wireway 9 ' is connected with the sidewall of outer bucket 3 '; The other end of wireway 9 ' is connected with a level sensor 10 ', and this level sensor 10 ' is electrically connected with control circuit board, and the water intaking valve 81 ' on the water inlet pipe 8 ' is is just opened and closed by this control circuit board control.And the interior barrel structure of washing machine; As shown in Figure 2; The top of interior bucket 2 ' is provided with gimbal 6 ', is vertically arranged with multiple row water hole 21 ' on the sidewall of interior bucket 2 ', and top side wall is provided with a circle spillway hole 22 '; Interior bucket 2 ' bottom is provided with spilled water hole 23 ', and this spilled water hole 23 ' also supplies the driving shaft 51 ' of drive unit 5 ' to run through simultaneously.
When washing machine was started working, water intaking valve 81 ' was opened, and running water is from water inlet pipe through water injection box 7 ' and flowing in barrel 2 '; Current in the bucket 2 ', also can be full of whole outer bucket 3 ' through the spilled water hole 23 ' of water hole 21 ' on the interior bucket 2 ' sidewall and interior bucket 2 ' bottom in being full of, also be; Outer bucket 3 ' is connected with interior bucket 2 ', and all being full of between outer bucket 3 ' and the interior bucket 2 ' has water, and an end of wireway 9 ' is connected with outer bucket 3 ' inside; So; Level sensor 10 ' just can detect the hydraulic pressure in outer barrel 3 ', interior barrel 2 ' constantly, controls the keying of water intaking valve 81 ' then, after the water in the interior bucket 2 ' reaches designated water level; Level sensor 10 ' is closed through control circuit board control water intaking valve 81 ', and washing machine then begins washing.
To sum up, existing washing machine, its water level control all is to realize through above-mentioned this wireway bound water level sensor.
But, because existing pulsator washing machine, all need be full of current between the sidewall of bucket and outer bucket in during laundry, and real current of participating in washing only in barrel in that part of, this makes water resource waste bigger; Meanwhile; Because current frequently pass in and out between interior bucket, outer bucket; After continuing to use; In zone between the sidewall of bucket and outer bucket also become the space of sheltering evil people and countenance evil practices, in the cellulose of the incrustation scale in the running water, the educt of washing powder, clothing, the organic matter of human body and the dust that clothing is brought into very easily are trapped in bacterium between bucket and the sidewall outward barrel.
Based on above-mentioned drawback, urge the internal barrel structure of people to improve, preferably; Be to select a kind of sealed interior bucket for use, as shown in Figure 3, bucket sidewall and bottom all seal setting in the sealing formula; Only be positioned near the upper edge, top and be provided with circle spillway hole and a rhone, so during washing machine work, current no longer flow into outer bucket with interior barrel between the zone; During dehydration, current in the interior bucket and the moisture content in the clothing are all discharged from rhone; Under this situation, there is not water between outer bucket and the interior bucket, the implementation of above-mentioned this wireway bound water level sensor just at all can't be in order to the height of the water level in the bucket in detecting.
The utility model content
The utility model technical problem to be solved is that a kind of digital water level control device that is applicable to the washing machine of sealed interior bucket is provided to above-mentioned prior art present situation, and it need not to come sensed water level according to the interior hydraulic pressure of outer bucket, and water level control is more accurate.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the digital water level control device of this washing machine; Comprise water intaking valve, the water injection box that communicates with water inlet pipe on the water inlet pipe that is installed in washing machine and be arranged on the washing machine and can control the control circuit board that water intaking valve opens and closes; It is characterized in that: also comprise the electronic flowmeter that is arranged on the water inlet pipe and coupled electronic flow signal generator; Wherein, Said electronic flow signal generator and control circuit board are electrically connected; This electronic flow signal generator can send to control circuit board with the inflow numerical signal of electronic flowmeter gained, and control circuit board opens and closes according to resulting Numerical Control water intaking valve.
Compared with prior art; The water-level control apparatus advantage of the utility model is: through the utilization of electronic flowmeter and electronic flow signal generator; Realized the digital metering and the control of inflow, abandoned thoroughly that traditional dependence hydraulic pressure detects, the mode of control water level, the metering of water level, control are more accurate; And make the sealed interior application of barrel technology in washing machine become possibility, very suitable.Simultaneously, the method for controlling water level of the utility model only relies on the digital data transmission of electronic flow signal generator, and step is simple, and the control of control circuit board more directly, effectively.
