Abstract
The utility model discloses a washing machine provided with a turbidity sensor, which comprises the turbidity sensor (4). The washing machine is characterized in that the turbidity sensor (4) is installed on a drain pipe (3); and an outgoing line of the turbidity sensor (4) is connected with a computer board of the washing machine (1). A control circuit (6) is connected with an output circuit (7) in parallel and then connected with an input circuit (5) in series so as to form the turbidity sensor; the input circuit (5) is formed by connecting a 5V voltage source and a resistor (R1) in series; an infrared light-emitting diode is sequentially connected with a resistor (R2) and a slide rheostat (4) in series so as to the control circuit (6); and an optocoupler triode is sequentially connected with a resistor (R3) and a resistor (R5) in series so as to form the output circuit (7). In the utility model, the turbidity sensor is installed on the drain pipe, and the structure is simple and the use is convenient. According to the identified result, the demanded rinsing times are controlled, thus achieving the function of saving water.
Description
Technical field
The utility model relates to a kind of washing machine, relates in particular to a kind of washing machine that is provided with turbidity sensor.
Background technology
Rotary drum washing machine on market at present, in entire work process, wash, the consumption of water has been got well by the program setting in the computer plate fully in the processes such as rinsing, procedure time is changeless, no matter how dirty clothing have, even clean clothing also will bear mode of washing and wash time than dirty linen, water wasting, take the electricity, time-consuming.During laundry at present, mainly judge by user's observation and experience whether clothing cleans up, do not judge yardstick accurately, thereby the number of times of uncontrollable rinsing uses for washing and brought great inconvenience.Along with development of times, society develops to the economizing type direction, needs the energy-conservation washing machine of a kind of energy.
The utility model content
In order to solve prior art problems, the purpose of this utility model is to provide a kind of washing machine that turbidity sensor is installed, it is simple in structure, easy for installation, can effectively detect the muddy degree of slurry by turbidity sensor, identify whether clothes is cleaned, thereby number of times, the time of control rinsing are played energy-conservation effect.
Technical solution adopted in the utility model is:
A kind of washing machine that turbidity sensor is installed comprises turbidity sensor 4, it is characterized in that: described turbidity sensor 4 is installed on the drainpipe 3, and the lead-out wire of turbidity sensor 4 is connected with washing machine 1 computer plate.
Aforesaid a kind of washing machine that turbidity sensor is installed is characterized in that: described turbidity sensor comprises input circuit 5, control circuit 6 and output circuit 7, and described control circuit 6 is connected in parallel with output circuit 7 and is connected with input circuit 5; Described input circuit 5 is composed in series by 5v voltage source and resistance R 1, and described infrared light-emitting diode and resistance R 2 and slide rheostat R4 are composed in series control circuit 6 successively, and described optocoupler triode and resistance R 3 and resistance R 5 are composed in series output circuit 7 successively.
Operation principle of the present utility model is: after the turbidity sensor energising, infrared light-emitting diode is luminous, light lotus root triode is at its opposite side, when water when passing through between the two, the turbidity situation of water can influence the power that light lotus root triode is accepted infrared light-emitting diode light, thereby make turbidity sensor under different turbidity situations, export different voltage, produced a feedback signal, thereby the computer plate that makes washing machine judge the washing machine clothes whether wash clean do not have, in the process of washing, if by judging that clothes cleans up, can reduce the quantity of rinsing, so just can reach the effect of water saving.
The beneficial effects of the utility model are:
The utility model is equipped with turbidity sensor on drainpipe, simple in structure easy to use.When rinsing finished draining, the computer plate was accepted the signal that turbidity sensor is sent, and identified the muddy degree of water, and the number of times according to the result who identifies controls the needs rinsing reaches the effect that economizes on resources.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model turbidity sensor circuit structure diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of washing machine that turbidity sensor is installed comprises turbidity sensor 4, and described turbidity sensor 4 is installed on the drainpipe 3, and the lead-out wire of turbidity sensor 4 is connected with washing machine 1 computer plate.
As shown in Figure 2, described turbidity sensor 4 comprises input circuit 5, control circuit 6 and output circuit 7, and described control circuit 6 is connected in parallel with output circuit 7 and is connected with input circuit 5; Described input circuit 5 is composed in series by 5v voltage source and resistance R 1, and described infrared light-emitting diode and resistance R 2 and slide rheostat R4 are composed in series control circuit successively, and described optocoupler triode and resistance R 3 and resistance R 5 are composed in series output circuit successively.
When rinsing is finished, washings in the washtub 2 discharge by drainpipe 3, detect feedback signal of generation by 4 pairs of different turbidity situations of turbidity sensor, washing machine 1 computer plate received signal, judge whether wash clean of washing machine clothes, control number of times, the time of needs rinsing according to the result who identifies, thereby realize cleaning the function of promptly stopping, finally reach the effect of water saving.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
