Description

Description: TECHNICAL FIELD The present invention utilizes a control device such as a microcomputer to control washing, rinsing, dehydration time and water flow intensity according to the state of laundry. The present invention relates to the control device.

2. Description of the Related Art Conventionally, a control device for a washing machine of this type has a configuration as shown in FIG. That is, it comprises a control means 1 for controlling a series of sequential operations of washing, rinsing and dehydration, and a switch group of a water flow changeover switch, a washing time changeover switch, a rinse changeover switch and a dehydration time changeover switch. An individual input unit 2 for individually setting and inputting the contents of the washing time, rinsing, and dehydrating time, and an individual display unit 3 for displaying the contents set corresponding to the individual input unit 2 are provided. The individual display means 3 includes a washing time setting display section 3a composed of a plurality of indicators for displaying the setting of the washing time, and as shown in FIG. From the rinse setting display section 3b composed of the indicator lamps for displaying, and the dehydration time setting display section 3c similarly composed of the indicator lamps displaying the setting of 5 ', 3', 1/2 'as the dehydration time. Has become. The operation of the motor 8 is controlled by controlling the bidirectional thyristors 5 and 6 of the drive circuit by the control means 1. Further, the voltage change across the phase advancing capacitor 7 of the motor 8 is detected by the capacitor voltage detecting means 10, and the load amount applied to the motor 8 from the voltage change detected by the capacitor voltage detecting means 10 is detected by the load amount detecting means. It is detected at 11 and a signal is given to the control means.

The control means 1 is composed of a microcomputer, and FIG. 3 shows the relationship between its basic configuration and external circuits. That is, the microcomputer receives the output of the individual input means 2 by a built-in program and outputs a signal to the motor drive means 12 composed of the bidirectional thyristors 5 and 6 and the motor 8.

Specifically, an input unit that receives the output of the individual input means 2
1b, an output unit 1d that outputs a signal to the motor driving means 12
And an operation control unit 1c that controls the internal storage unit 1a, the input unit 1b, and the output unit 1d to perform a data comparison operation.

By the control of the control means 1, the one bidirectional thyristor 5 is kept in the off state and the other bidirectional thyristor 6 is intermittently turned on and off repeatedly to drive the motor 8. When the motor 8 is started, the voltage change across the capacitor 7 is detected by the capacitor voltage detecting means 10
The load amount applied to the motor 8 is detected by the load amount detecting means 11 according to the time until the voltage value reaches a predetermined voltage value. Then, on the basis of the detected load data, the washing, rinsing, dehydration time and the strength of the water flow are controlled, and the contents of the display section composed of a plurality of indicator lights of the individual display means 3 are corrected each time. It was a thing.

Problems to be Solved by the Invention In such a conventional configuration, when the user is laundering, load detection is always performed regardless of whether he / she desires, and time and water flow strength are automatically controlled. In addition, since the displayed contents change each time, the user may be mistaken for malfunction. Further, there is a problem that the contents set by the load amount detection cannot be displayed because the type or number of display units is limited.

The present invention solves such a problem by allowing the user to control the subsequent process by load amount detection at any time, and at that time, the displayed contents do not change each time, so that the user can The purpose of this is to display at a glance that the load detection control is being performed and store the user's desired settings so that it is not necessary to reset the settings at each washing. Is.

Means for Solving the Problems In order to solve this problem, the present invention uses a changeover switch which is a conventional individual input means as it is, and a rinse setting constituted by a plurality of indicator lamps as a display means. One sensor indicator lamp is provided for each of the display unit and the dehydration time setting display unit, and setting storage means for storing the setting contents of each is provided.

Operation With this configuration, when washing, the user can use the conventional changeover switch which is an individual input means as it is, and only when desired, automatically control the process time and the strength of the water flow by detecting the load amount, It is possible to wash under the optimal conditions.As a display method at that time, by providing a dedicated sensor indicator light, it is clear that the load amount is being detected or the process is being controlled, and there is a concern that it may be mistaken for malfunction. Disappear. Then, by storing the setting contents in the setting storage means, it becomes unnecessary to reset the setting at each washing.

Example Hereinafter, an example of the present invention will be described with reference to FIGS. 1, 2, and 4. In the figure, description of the same parts as those in the conventional example will be omitted. In FIG. 1, as the individual display means 3, as shown in FIG. 2, 3b is a rinse setting display section which is composed of indicator lights for displaying detailed, standard, speed and sensor settings as rinse types. is there. Here, the sensor indicator light is an indicator light for indicating that it is under control so as to automatically set the optimum process time and water flow intensity according to the amount of laundry by detecting the load amount.
Denoted at 3c is a dehydration time setting display section which is similarly composed of 5 ', 3', 1/2 'as dehydration time and an indicator lamp for displaying sensor settings. Reference numeral 4 denotes a setting storage means for storing the setting content displayed by the individual display means 3, which is constituted by a non-volatile memory and stores the setting content even after the power of the washing machine is turned off.

When the power of the washing machine is turned on, the control means 1 inputs the setting of the washing time, rinsing and dehydration time from the setting storage means 4 and displays the setting contents on the setting display means 3. The control means 1 controls the rinse setting display section 3b and the dehydration time setting display section of the individual display means 3 according to the settings input from the setting storage means 4.
In the case of displaying a sensor indicator lamp among a plurality of indicator lamps constituting 3c, and by the user, the sensor indicator lamp is similarly selected by the rinse changeover switch or the dehydration time changeover switch constituting the individual input means 2. Only then, based on the load amount detected by the load amount detecting means 11 during intermittent dehydration, the subsequent rinsing, dehydration time and water flow strength are set and controlled.

Therefore, if only the sensor indicator lamp in the rinse setting display section 3b is selected, the sensor indicator lamp in the dehydration time setting display section 3c is controlled by controlling only the time during the rinsing process and the strength of the water flow. If only one is chosen, only the time during the dehydration process will be controlled.

After the completion of all the steps, the operated setting contents are output to and stored in the setting storage means 4.

Next, the operation of this embodiment will be described using a flowchart. FIG. 4 shows a main part of a flow chart under the control of the control means 2.

After the power supply of the control means 2 is turned on, the setting storage means 4 is set in step 21.
Further, each setting of the washing time, rinsing and dehydration time is input, and in step 22, each setting is displayed on the setting display means 3. In step 23, it is judged whether or not the rinse changeover switch is pressed. If it is pressed, it is judged in step 24 whether or not the sensor is selected, and if it is selected, the sensor indicator lamp is turned on in step 25. If it is not selected, the special, standard or speed indicator light is turned on. In step 34, the control means 1 determines whether or not the dehydration time changeover switch has been pressed, and if so, it determines whether or not the sensor has been selected in step 35, and if so, the sensor indicator lamp is turned on in step 36. Light. If not selected, turn on the indicator light of 5'or 3'or 1/2 '. And when the sensor is selected, step 26
Then, the control means 1 determines whether it is an intermittent dehydration process. If it is an intermittent dehydration process, the load amount is detected in step 27, and based on that, the subsequent process time is controlled in step 28, and the water flow strength is controlled in step 29. In step 30, it is judged whether or not the operation of each process is completed. If all the processes are completed, in step 31, the washing time, rinse and dehydration settings are output to the setting storage means 4 and stored therein.

In this embodiment, the non-volatile memory is used as the setting storage means, but the volatile memory may be stored in a battery or the like as long as the setting contents can be stored even after the power of the washing machine is turned off. . Further, in the present embodiment, the setting content is stored after the completion of all the steps, but the setting may be stored each time the individual input means 2 inputs.

EFFECTS OF THE INVENTION As is clear from the above description of the embodiments, according to the present invention, the user automatically controls the rinsing, the dehydration time and the strength of the water flow by detecting the load amount only when desired when washing. It is possible to wash in an optimal state by doing so, and as a display method in that case, it is possible at a glance that load amount detection or process control is being performed by providing a dedicated sensor indicator lamp on the individual display means for display. As the display contents do not change each time, there is no fear of mistaken operation, and since the setting contents of washing, rinsing, and dehydration are stored in a non-volatile memory, the user can set each washing. There is no need to re-do, and there is an effect that only the desired process can be automatically controlled and the washing can be performed in the optimum state with one touch.
