Detailed description of the invention
Washing machine, in order to detect the dirty degree of laundry water in laundry processes, to avoid producing overwass, water wasting expense electricity or situation about not washing clean, is typically provided with the turbidity transducer for detecting laundry water dirt degree in washing machine.Turbidity transducer is typically arranged on the position of drain valve or drain pipe by existing washing machine, thus, turbidity transducer can only detect in drainage procedure, and easy residual foam at drain valve or drain pipe, turbidity transducer is affected by residual foam, cause testing result inaccurate, easily produce the situation of overwass.In order to solve the problems referred to above, the present embodiment proposes a kind of rotary drum washing machine, including outer barrel and inner barr, turbidity transducer for detecting laundry water dirt degree is installed in outer barrel, being provided with groove bottom the inwall of outer barrel, be provided with discharge outlet in groove, turbidity transducer is installed in groove.Due to waterflow stabilization near discharge outlet, the water yield is relatively big, all can detect the dirty degree of water in laundry and drainage procedure, it is possible to avoid dirty deposition to affect the accuracy of turbidity transducer detection.
Concrete, as Figure 1-3, the present embodiment rotary drum washing machine includes outer barrel 1 and interior bucket (not shown), the bottom of outer barrel 1 has discharge outlet 11, connecting in discharge outlet 11 and have drain pipe and drain valve, when drain valve is opened, discharge outlet is for discharging the laundry water in outer barrel 1.In order to improve drainage effect, groove 12 it is provided with bottom the inwall of outer barrel 1, discharge outlet 11 is arranged in groove 12, due to waterflow stabilization in groove 12, the water yield is relatively big, and during laundry and draining, the water in groove 12 is all flowing, thus, the turbidity transducer 2 of detection laundry water dirt degree is arranged in groove 12 by the present embodiment.During washing of drum type washing machine medicated clothing, rotated by impeller, add that the common effect of detergent and water makes clothes washing clean.Judge the standard that clothes washing is clean, i.e. detected the dirty degree of laundry water by turbidity transducer 2, when the dirty degree of laundry water is reduced to setting value, then it is assumed that washes clean, washing can be terminated.Turbidity transducer 2 is arranged in the groove 12 of outer barrel 1 by the present embodiment, and dirt can be avoided to deposit to the surface of turbidity transducer 2, makes turbidity transducer 2 produce erroneous judgement, causes rinsing times to increase, cause energy waste.
In order to avoid dirty being deposited on turbidity transducer 2 further, reduce the accuracy of turbidity transducer 2 detection, as it is shown on figure 3, the lowest part of the transmitting terminal 21 of turbidity transducer 2 and receiving terminal 22 is higher than the lowest part on groove 12 surface.Thus, the surface of turbidity transducer 2, every time when turbidity transducer 2, all can be washed away by washings, prevents the dirty surface being deposited on turbidity transducer 2, affects accuracy of detection.
First below the structure of turbidity transducer 2 is illustrated.
As shown in Figure 4,5, turbidity transducer 2 includes a cylindrical matrix 24, and the side of cylindrical base 24 is provided with installation portion, and installation portion is installed on the outer wall of outer barrel 1.It is provided with transmitting terminal 21 and receiving terminal 22, transmitting terminal 21 and receiving terminal 22 on one end face of cylindrical base 24 and is used for detecting the dirty degree of laundry water, be positioned at outer barrel 1.Being provided with signal output part 25 on another end face of cylindrical base 24, signal output part, for being exported by detection signal, is positioned at outside outer barrel 1.
Wherein, installation portion includes at least two mounting ear 23 being installed on turbidity transducer 2, offers installing hole on mounting ear 23, and installing hole can be screwed hole.The mounting ear 23 of turbidity transducer 2 is installed on the outer wall of outer barrel 1 by screw or bolt.
Light-emitting component is installed on the end face of transmitting terminal 21, the end face of receiving terminal 22 is provided with photo-sensitive cell.The light-emitting component of transmitting terminal 21 sends a number of light, the photo-sensitive cell of receiving terminal 22 is arrived through liquid in bucket, photo-sensitive cell is according to the quantity accepting light, feeding back different magnitudes of voltage to the control system of washing machine, the control system of washing machine judges the dirty degree of liquid in bucket according to the size of magnitude of voltage.
In the present embodiment, light-emitting component connects with the computer board of washing machine with the lead-out wire of photo-sensitive cell.When liquid within the cartridge is in time passing through between transmitting terminal 21 and receiving terminal 22, the dirty degree of liquid in bucket can affect the power of the photo-sensitive cell reception light of receiving terminal 22, photo-sensitive cell produces a feedback signal according to light intensity, by signal by signal output part 25 feedback to the computer plate, with this, computer board judges that washings is the cleanest, reach Based Intelligent Control washing machine.
Secondly, outer barrel 1 is illustrated with turbidity transducer 2 mounting means.
The installing hole 3 of circle is offered in groove 12 bottom the inwall of outer barrel 1, turbidity transducer 2 is installed at installing hole 3, wherein, the transmitting terminal 21 of turbidity transducer 2 and receiving terminal 22 are positioned at the inner side of outer barrel 1, and the signal output part of turbidity transducer 2 is positioned at the outside of outer barrel 1.
The cylindrical base 21 of turbidity transducer 2 is coordinated with installing hole 3 by sealing ring 4, and sealing ring 4 is possible to prevent outer barrel 1 to leak.Preferably, being provided with sealing ring mounting groove 13 on the outer wall of outer barrel 1, sealing ring 4 is positioned in sealing ring mounting groove 13, and turbidity transducer 2 contacts with sealing ring 4.
Being provided with at least two mounting post 14 on the outer wall of outer barrel 1, the mounting ear 23 of turbidity transducer 2 is fixed in mounting post 14.Preferably, being provided with screwed hole in mounting post 14, mounting ear 23 is installed in mounting post 14 by screw or stud.
The mounting ear 23 of turbidity transducer 2 is installed on the outer wall of outer barrel 1 by screw or bolt, it is internal that the transmitting terminal 21 of turbidity transducer 2 and receiving terminal 22 stretch into outer barrel 1 by installing hole 3, mounting means the most easily realizes, and the volume in outer barrel 1 will not be taken, the most important thing is, turbidity transducer 2 convenient maintenance and replacement.
In sum, the present embodiment rotary drum washing machine, by changing installation site and the mounting means of turbidity transducer, improves the accuracy of washing machine liquid in bucket dirt degree detecting.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
