【発明の詳細な説明】 〔産業上の利用分野〕 本発明は洗濯機、さらに詳細には、衣類の布質を判断
する洗濯機の制御装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine, and more particularly, to a control device for a washing machine that determines the quality of clothing.
従来の洗濯機には、衣類の量に応じて水流および洗い
時間を決定する方式がある。2. Description of the Related Art A conventional washing machine has a method of determining a water flow and a washing time according to the amount of clothes.
従来の技術では、一般に衣類の量によって水流，洗い
時間などを決定しており、例えば衣類の量が少ない場合

ランジェリ等の薄物衣類を多く洗った場合は衣類の傷み
が懸念され、最適な洗濯機の制御方法に至っていない。In the prior art, the water flow and the washing time are generally determined according to the amount of clothing. For example, when the amount of clothing is small, the washing time is reduced with a weak current, and when the amount of clothing is large, the washing time is increased with a strong current. Because it was long, the washing power was weak when washing large clothes such as sheets and bath towels a little,
When a lot of thin clothes such as lingerie are washed, there is a concern that the clothes may be damaged, and an optimum method of controlling a washing machine has not been achieved.
本発明の目的は、衣類の布質を判断するための布質の

することによって達成される。The object is to provide an outer frame, an outer tub suspended in the outer frame, a washing and dewatering tub provided in the outer tub, and a stirring blade rotatably installed in the washing and dewatering tub. A motor that rotationally drives the agitating blades and the washing and dewatering tub, a cloth quality detection unit that detects the quality of clothing put into the washing and dewatering tub, and tap water into the washing and dewatering tub. In the washing machine having a water supply means for injecting water, the cloth quality detection means supplies tap water to the washing and dewatering tub at a predetermined water level by the water supply means, and then the clothes put into the washing and dewatering tub are washed with the cloth. The stirring blade is rotated intermittently a plurality of times, and the back electromotive force of the motor generated during the inertial rotation of the stirring blade to stop is detected as a terminal voltage of a driving capacitor of the motor, and a cycle of the terminal voltage is detected. After obtaining, the tap water is washed and removed by the water supply means. Water to the bath, rate of change in the cycle of the terminal voltage when changing the water level, is achieved by a structure for determining the quality of the clothes based on the rate of change of the cycle.

位まで給水する。In the cloth amount detection process, reverse stirring is performed for 0.4 seconds ON-1 second OFF, and the back electromotive force of the motor 8 when the rotating body 6 rotates by inertia at the time of OFF is converted to the terminal voltage of the motor 8 driving capacitor 8a. detecting Te, which was converted into a DC square wave pulse, is to determine the laundry weight by measuring the time t 1 between the pulses.
Namely when the laundry is large large resistance to the rotating body 6, the time t 1 between impeded coasting pulse becomes longer, the time between pulses opposite in the case where the amount of laundry is small
t 1 becomes shorter. The time between pulse measurement measures the width t 1 rise time of 3 shot th pulse of one shot th pulse of pulse-wave detection which detects (i) (ii) in the circuit shown in FIG. 3 ( This is repeated 20 times, and the total time is compared with the relationship between the washing amount and the time stored in the microcomputer in advance, the washing amount is determined, the water level is automatically set according to the washing amount, and the water is supplied to the specified water level.

ΔＴを求める。Further, in the step of supplying water to the optimum level, by changing the detection level, performs the above-mentioned cloth amount detection step, measuring the width t 1 of the pulse rise time. For example, when it is determined that the laundry level is 4.0 kg and the water level is high, the laundry amount detection process is performed four times, and the types of laundry of different types of clothing (large clothing such as sheets and bath towels and thin clothing such as lingerie). The pulse rise time width t 1 at each water level is as shown in FIG. 5, and the difference ΔT between the pulse rise time width t 1 at the minimum water level and the optimum water level is obtained.

に高くなる。From the above, it is possible to determine the type of clothing based on the magnitude of the change rate ΔT and m of the pulse rise time width t 1 when the detected water level is changed. For example, ΔT and ΔT of large clothing such as sheets and bath towels can be determined. Since m is large and thin objects such as lingerie are small, the strength of water flow suitable for various kinds of clothes (for example, motor By controlling the ratio of the ON time to the OFF time of the energizing time and the OFF time and the number of rotations), washing, rinsing, dehydrating time, etc. By shortening the time with the water current, it becomes possible to control the washing that suits various kinds of clothing. In addition, it is possible to determine the type of clothing based on the amount of fluctuation (maximum value-minimum value) and the magnitude of the deviation value due to the number of detections (20 times in this embodiment) during the above-described cloth amount detection process. sixth variation value R 1 of garments stiff jeans such as diagrams of order greater than thin clothing variation value R 2 such as plugs, a table constant depending on the type of clothing that is set in the microcomputer in advance control device In comparison, the types of clothing are determined, and the above-described washing process is performed. Further, the accuracy is further improved by using a combination of the clothing type discriminating means described above.
