Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention uses a control device such as a microcomputer to wash and rinse laundry according to its condition.

The present invention relates to a washing machine control device that controls spin-drying time and water flow strength.

BACKGROUND ART Conventionally, a control device for a washing machine of this type has a configuration as shown in FIG. That is, the input means 1 is a switch for setting and inputting each content of water flow, washing time, rinsing, and spin-drying time, and is composed of a group of switches including a water flow selector switch, a wash time selector switch, a rinse selector switch, and a spin-dry time selector switch. .

The control means 2 controls a series of sequential operations of washing, rinsing, and dehydration, and the input switch discriminating means 2a
A process content determining unit 2b that discriminates the type of switch of the input unit 1 and determines the process content selected by the input unit 1, a storage unit 2d that stores predetermined process content, and a load described below. A series of sequential operations of washing, rinsing, and dehydration are controlled by the control unit 2 based on the signal from the amount detecting means 1o. The display means 3 displays the setting contents of the input means 1, the washing time setting display section 3a is composed of a plurality of indicator lights for displaying the washing time setting, and the rinse setting display section 3b is shown in FIG. As shown, kurayiri as a type of rinse.

Consists of indicator lights that display the standard and speed settings, and the dehydration time setting display section 3C similarly displays the dehydration time as 5/,
It consists of an indicator light that displays the setting of 319%'. The control means 2 also drives the motor 7 by means of a bidirectional thyristor 4.6. 6 is a phase advance capacitor, and 8 is an AC power supply. The capacitor voltage detection means 9 is the capacitor 6.
The load amount detection means 1o detects the amount of load applied to the motor 7 based on the detection signal.

Under the control of the control means 2, while the one bidirectional thyristor 4 remains off, the other bidirectional thyristor 6 is intermittently turned on and off to drive the motor 7. When the motor 7 is started, the voltage change across the capacitor 6 is detected by the capacitor voltage detection means 9, and the amount of load applied to the motor 7 is calculated based on the time it takes to reach a predetermined voltage value. The amount is detected by the amount detection means 10. Based on the detected data, washing, rinsing, spin-drying times, and the strength of the water flow were controlled.

Problems to be Solved by the Invention In such a conventional configuration, when a user washes clothes, load amount detection is always performed regardless of whether the user wishes to do so or not, and the time and water flow strength of the entire process are automatically controlled. You end up doing it. For example, there is a problem in that it is not possible to control only rinsing or dehydration, not to control rinsing or dehydration, or to increase or weaken the strength of the water flow.

The present invention is intended to solve these problems, and aims to allow the user to control the process by detecting the load amount at any time.

Means for Solving the Problems In order to achieve the above object, the washing machine control device of the present invention includes input means for setting each process content of washing, rinsing, and spin-drying steps or automatic control by a sensor, respectively;
A control means for controlling a series of sequential operations of each step is provided, and the control means is configured to perform control by sensor detection only when the above equation 1 is satisfied.

Function: When washing clothes, the user can automatically control the process time and the strength of the water flow by detecting the load amount and wash clothes under optimal conditions only when desired.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1, 2, and 3. Components that are the same as those in the conventional configuration are given the same reference numerals, and detailed explanation thereof will be omitted. In FIG. 1, the rinse setting display section 3 in the display means 3
As shown in Figure 2, b indicates the type of rinsing: sensor, penetration, and standard.

It consists of an indicator light that displays the speed setting.

Here, the indicator light of the sensor is an indicator light for indicating that control is in progress to automatically set the optimum process time and water flow strength according to the amount of laundry by detecting the load amount. Similarly, in the dehydration time setting table, display section 3c shows sensors 5' and 3' as the dehydration time.

It consists of an indicator light that displays the %' setting. Further, the control means 2 is composed of a microcomputer, and the switching means 2
C is for switching the control section 2e to be controlled only by the load amount detection means 1o only when the process content determination means 2b determines that automatic control by the sensor is set.

Only when automatic control by sensor is selected by the user using the rinse selector switch or dehydration time selector switch that constitutes the input means 1, the load amount detected by the load amount detection means 1o during intermittent dehydration is Control subsequent rinsing, dehydration time and water flow strength accordingly. Therefore, when the sensor indicator light in the rinse setting display section 3b is selected, the time and strength of the water flow during the rinsing process is controlled, and when the sensor indicator light in the dehydration time setting display section 3c is selected, the dehydration process is performed. will be controlled.

Next, the operation of this embodiment will be explained using a flowchart. FIG. 3 shows the main part of a flowchart under the control of the microcomputer 2.

In step 11, the microcomputer 2 uses the input switch determining means 2a to determine whether the rinse changeover switch has been pressed, and if it has been pressed, in step 12, the process content determining means 2b determines whether the sensor has been selected. If so, the sensor indicator light in the rinse setting display section 3b is turned on in step 13. If it is not selected, in step 18 the lover, standard or speed indicator light is turned on. Further, in step 19, the microcomputer 2 uses the input switch determining means 2a to determine whether or not the dehydration time selection switch has been pressed, and if it has been pressed, the microcomputer 2 determines whether the sensor has been selected by the process content determining means 2b in step 2o. , if selected, the sensor indicator light of the dehydration time setting display section 3c is turned on in step 21. If it has not been selected, the indicator light 6', 3' or %' is turned on in step 22.

When the sensor is selected, the microcomputer 2 determines in step 14 whether or not an intermittent dehydration process is being performed. If the intermittent dehydration process is in progress, the load amount is detected in step 16, and based on that, the subsequent process time is determined in step 16,
7 to control the strength of the water flow.

In this example, the amount of laundry was detected and the process was controlled by detecting the voltage across the capacitor voltage in the motor, but other sensors that detect ultrasonic waves, light, etc. ,weight.

It is also possible to detect various conditions of the laundry, such as the degree of dirtiness or temperature of the water, and control the washing process according to these conditions.

Effects of the Invention As described above, according to the present invention, when washing clothes, the user can:
Only when desired, it is possible to automatically control rinsing, dehydration time, and water flow strength by detecting the load amount to wash in the optimal condition. For example, it is possible to control only during rinsing or dehydration, and it is possible to respond to the process time specified by the user without controlling only during rinsing or dehydration.
