Embodiment Construction

[0014] see figure 1 , the present invention is a washing machine with intelligent rinsing function, which is equipped with a turbidity sensor and a control panel, the turbidity sensor is implanted in the drain pipe, and the turbidity sensor detects the rinsing water in the dehydration state of the rinsing process when the motor rotates The resulting foam is tested.

[0015] Connect the wiring terminal to the control board through the output sampling line. The turbidity sensor is driven by the PWM power supply, and the emitter of the turbidity sensor emits to the receiver.

[0016] The sampling and measuring device AD ​​on the control board is connected with the microprogram controller MCU, and the microprogram controller MCU is connected with the power source PWM. The control circuit on the control board is connected with the turbidity sensor and connected with the microprogram controller MCU.

[0017] The drainpipe is bent to have a certain height, and the turbidity sensor...

Abstract

The invention relates to a washing machine capable of intelligently rinsing, which is provided with a turbidity sensor and a control panel. The turbidity sensor is arranged in a drain pipe and detects the foam generated in the rising water during the rotation of a motor in a dewatering state in a rinsing process, a wire connecting terminal is connected with the control panel by an output sampling wire, the turbidity sensor is driven by a power supply, and a transmitting pole of the turbidity sensor transmits toward a receiving pole. A sampling measurement device arranged on the control panel is connected with a microprogrammed control unit connected with the power supply. A control circuit arranged on the control panel is connected with the turbidity sensor and carries out calibration and examination through the calibration of the turbidity sensor and the sampling circuit. The machine judges whether further rinsing is needed according to rinsing foam turbidity detected by the turbidity sensor after each rinsing, thereby achieving good rinsing effect and effectively avoiding waste of water and electric energy.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine with an intelligent rinsing function. Background technique [0002] Existing fully automatic washing machines generally have a fixed number of rinses, or users can choose the number of rinses by themselves. This type of washing machine cannot make a relatively accurate judgment on the number of rinses according to different situations such as different clothes loads, detergent usage, and washing water levels during actual laundry by the user. The washing machine of this kind of rinsing method will produce the problem of insufficient or too many times of rinsing when washing clothes. If the number of times of rinsing is not enough, a good rinsing effect cannot be achieved, and if the number of times of rinsing is too many, the amount of water and electric energy will be wasted. [0003] When rinsing clothes, the turbidity of the rinse water is very low, and the turbidity NT...
