Of the display unit 12 for displaying various functional states according to the control signal of 11), the buzzer sound generating unit 13 for generating a buzzer sound under the control of the microcomputer 11 at the time of an error, and the microcomputer 11 A load driving unit 14 which is switched on and off according to the control operation to supply operating power to the motor 4, and a water level sensing unit 15 which detects the water level of the water supplied into the washing tank and inputs it to the microcomputer 11; , A water supply valve 17 for supplying water in the washing tank, and a drain valve 9 for draining turbid water when the washing is completed.

In the conventional washing machine configured as described above, when the user selects and operates only the washing stroke, the user first puts laundry and detergent into the washing tank 1, sets the washing stroke by pressing the washing key through the key input unit 10, and sets the washing time. When set, the microcomputer 11 initially determines the water level according to the amount of laundry, and then turns on the water supply valve 17 through the load driving unit 14 to supply hot water and cold water to the washing tank 1 up to the set water level. At this time, when the water supply in the washing tank 1 is completed to a certain level, the water level detector 15 detects the water level in the washing tank 1 and inputs it to the microcomputer 11.

The microcomputer 11 compares the water level input from the water level detecting unit 15 with the set water level, and turns off the hot water and cold water valves 2 'and 2 through the load driving unit 14 so that no more washing water is supplied. Do not At the same time, the motor 4 is rotated clockwise and counterclockwise alternately during the set washing time.

The rotational force generated by the motor 4 is transmitted to the pulsator 8 through the pulleys 5 '5, the V belt 6, and the clutch 7 to wash the laundry.

When washing is completed in this manner, the microcomputer 11 turns on the drain valve 9 through the load driving unit 14 to drain the turbid water in the washing tank 1 to complete the washing administration.

When all the strokes selected by the user are finished, the microcomputer 11 displays the user visually as shown in the display unit 12, such as End, and drives the buzzer sound generator 13 to make a buzzer sound for a predetermined time.

In addition, if water is not supplied to the set water level within a predetermined time in the washing administration, the microcomputer 11 determines that the water supply is abnormal and stops all the operations and notifies the occurrence of an abnormal state of the washing machine. It indicates an error and makes a buzzer sound for a certain time. In this case, OE in case of drainage error, UE in case of unbalance error, and dF in case of door open error are displayed on the display unit 12 as well as buzzer sound generation unit 13 as in the case of water supply. To control the buzzer sound.

The buzzer sound generated at this time may be determined as shown in FIG. 3 differently from the buzzer sound at the end of the administration. And the operation flow during the washing administration is as shown in FIG.

However, in the prior art, when an error (IE, OE, UE, dF) occurs due to the immaturity of the consumer, an error indication and a buzzer sound on the display unit when the washing machine stops operating. There is a hassle to look for the instruction manual for the indication of, and if there is no instruction manual, a problem such as a malfunction of the washing machine and a request for repair to the service center occurs.

Therefore, in order to solve the conventional problems, the present invention is to create a voice control method of the washing machine so that consumers can easily know the cause by informing each other of the abnormal state by voice when the abnormal state occurs in the washing machine. When described in detail with reference to the accompanying drawings as follows.

5 is a block diagram of a washing machine equipped with a voice generator of the present invention, as shown in FIG. 5, which controls the overall washing machine system operation according to a user's selection key signal input from the key input unit 10; The display unit 12 displays various functional states according to the control signal of the microcomputer 11, and is switched on and off according to the control operation of the microcomputer 11 to supply operating power to the motor 4. The load driving unit 14, the water level detecting unit 15 which detects the water level of the water supplied into the washing tank and inputs it to the microcomputer 11, and generates the situation according to the contents when an error occurs due to each situation during washing. And a sound generation unit 16, a water supply valve 17 for supplying water into the washing tank, and a drain valve 18 for draining turbid water when the washing is completed.

In addition, the voice generator 16 includes an address ADD output from the microcomputer 11 as shown in FIG. A voice IC 19-1 for recognizing a voice according to a pulse, and an amplifying unit 19-2 for amplifying the voice to a predetermined level when the voice corresponding to the address is output from the voice IC 19-1; And a volume controller 19-3 which adjusts the volume of the voice input from the amplifier 19-2 according to the control signal and outputs the volume to the speaker SP.

Referring to the operation and effects of the present invention configured as described above in detail.

As described with reference to the flow chart shown in Figure 7 with respect to the washing administration as in the prior art, when the user puts the laundry and detergent in the washing tank and press the washing key through the key input unit 10 to set the washing administration and washing time micro The computer 11 turns on the water supply valve 17 by controlling the load driving unit 14 to supply the laundry to the set water level according to the laundry.

Accordingly, the water is supplied to the washing tank through the water supply valve 17 to a predetermined level. When water is supplied to the washing tank to a predetermined level, the water level detecting unit 15 detects the water level in the washing tank 1 and inputs it to the microcomputer 11. The microcomputer 11 compares the input water level with the set water level, and if it is the same, turns off the water supply valve 17 through the load driving unit 14, and then rotates the motor 4 clockwise and counterclockwise to wash time. Wash it for a while.

However, when the water supply valve 17 is turned on to supply water to the washing tank, if the water supply is not completed within a predetermined time within a predetermined time, the microcomputer 11 determines that the water supply error occurs and drives the display unit 12 together with the IE. Look through the voice generator 16 to see if the water enters well.

In addition to the error as described above, when the selected stroke is completed, the display unit 12 displays End, and the voice generating unit 16 generates a voice message indicating that the washing is finished, and during each stroke of washing and rinsing dehydration. If the voice confirmation key of the key input unit 10 is pressed, a message is generated regarding the ongoing administration such as washing is in progress. The voice contents thereof are as shown in FIG.

The operation of the voice generator 16 will now be described with reference to the flowchart of FIG. 9.

In order to generate a voice, first, power is supplied from the microcomputer 11 to the speaker SP, and the volume of the voice volume (eg, weak) is input by the volume control key of the key input unit 10. 19-3). Then, the address 1 (ADD1) data corresponding to the first bar of the voice and The pulses are output to the voice IC 19-1 in the same waveform as the eighth (b) and (a).

Then, the voice IC 19-1 recognizes data input through the address line only when the input of the ST port is low, and outputs the voice corresponding to the address to the amplifier 19-2. At this time, if the signal AOUT output from the voice IC 19-1 to the amplifying unit 19-2 is output as analog as shown in (d) of FIG. 8, the microcomputer ( Busy port to 11) The output goes low as in (c) of Figure 8 and goes high when the analog output ends.

Therefore, in order to output the address ADD2 of the well, the busy line in the microcomputer 11 Check and change from low to high to output address ADD2 to voice IC 19-1 and to output SP pulse.

When the output of all voices to be generated in this way is finished, the power supplied to the speaker SP is cut off to eliminate electrical noise of the speaker SP.
