The present invention relates to a pronunciation control of a home telephone apparatus, in particular a washing machine, having sound generating means.

Conventionally, home telephone apparatuses equipped with sound generating means have been known, but mainly by buzzers. As a conventional home telephone apparatus equipped with such a Myeong-dong detector, Japanese Patent Laid-Open Publication No. Hei 4-197390, Japanese Patent Laid-Open Publication Hei 3-188987 and Japanese Patent Laid-Open Publication No. 63-214282 You can pick up a washing machine. They are equipped with a myeongdong device such as a buzzer in the washing machine, and sound when the washing machine stops running or an error occurs. One example is the volume that is initially small, and gradually increases over time. In the latter two cases, a melody generating means is provided to generate high melody at the start or end of washing.

The conventional example described in Japanese Patent Application Laid-Open No. Hei 4-197390 is to notify the user of the operation termination of the washing machine or the occurrence of abnormality by the sound of the Myeong-Dong. Therefore, no consideration has been given to the setting of the washing operation by pressing the operation button of the washing machine and the notification of the progress of washing by sound. For this reason, the visually impaired person who has difficulty in viewing and confirming the display apparatus cannot recognize the correct setting of the washing operation and the progress of washing by sound.

In addition, even if the lighting time and the volume of the Myeongdong Gorge are controlled, the height of the tone is constant, so the tone is monotonous, and the type of the tone that is pleasant to be heard by the user is limited. In addition, it is difficult to express the tone by pressing the tone button and expressing each washing process in a different tone.

In addition, since the control of the volume is performed by controlling the amplitude of the voltage applied to the Myeong-dong detector, a means for generating a variable voltage such as a D / A converter is required.

In addition, the prior art described in the above-mentioned Japanese Patent Publication No. Hei 3-188987 or Japanese Patent Laid-Open Publication No. 63-214282 is intended to inform the user of the end of the washing machine or the occurrence of an abnormality by a melody sound. You can choose your favorite melody, and the latter allows you to register and use your own melody. However, when the operation button switch (hereinafter referred to as an operation button) is pressed, there is a lack of means for informing the user about the set value of the operation button washing and the washing operation, and the user has correctly accepted the button operation. It is difficult to set the operation to ensure that the washing operation is performed correctly for the visually impaired who cannot obtain a sense of security, and is particularly difficult to see and confirm the display device. In the latter case, it is inconvenient to check whether or not the intended melody is correctly input when the user inputs the melody created by the user by operating the operation button. In addition, cost increases because a special melody generating means such as a melody IC is required.

In addition, the conventional apparatus is not considered to increase or decrease the high pitch sound by a sound volume appropriate to the user's preference, and further increases the cost by using a special volume increasing means such as a conventional volume adjusting dial to increase or decrease the volume. Becomes

(From these two hits, it becomes the scale of 'Le', 'Mi', 'Pa').

Here, in the present specification, "sound" means sound of an audible frequency band, and "volume" means sound pressure level at a predetermined distance.

When the control means reads the signal by pressing the operation button, it immediately calculates and outputs a sound signal. As a result, the sound is generated by the sound generating means at the same time as the operation button is pressed. By varying the volume, tone, frequency, and duration of the sound signal for each operation button, a sound of a different tone can be generated according to each operation button. When the same button is pressed once, the setting value of the device operation is changed by the so-called toggle operation. The sound of a different tone can be generated according to each setting value.

In addition, since the control means executes the operation control of the device and calculates and outputs the sound signal, the control signal is calculated and generated immediately at the end of each step of the device operation or at the occurrence of the error. The generation can be notified to the user by the sound of a different tone according to each process or type of abnormality.

In addition, when the sound signal is a square wave with a constant voltage amplitude, the time ratio of the presence or absence of the voltage in one cycle is controlled so that the volume control can be performed without the need for a variable voltage generation circuit.

In addition, if a specific button is provided on the operation button and the button can be set to stop all or part of the sound generation or to reduce the volume in advance, the user may be bothered by the generation of unnecessary sound or disturb the people around. There is no work.

When the control means reads a signal generated by pressing the operation button, at least one element of the volume, frequency, or duration according to the type of operation setting value or operation button causes the sound generation means to sound. At the start, end or abnormality of each process in the washing operation, the sound generating means is sounded so as to generate a sound corresponding to the above-mentioned each process or type of abnormality, and the volume control is executed.

EMBODIMENT OF THE INVENTION Hereinafter, Embodiment 1 of the washing machine which is one of the typical home telephone apparatuses is demonstrated, referring drawings. 1 is a diagram showing the configuration of Embodiment 1 of a washing machine according to the present invention. The operation button 1 is a group of buttons for the user to set the washing operation such as driving, stopping or washing time of the washing machine, rinsing frequency, and the like. The control unit 2 is an arithmetic control unit which reads the signal from the operation button 1 and executes the operation control of the washing machine according to this, and is a commercially available microprocessor or the like. The display panel 3 is a fluorescent display panel for displaying a set value of the washing operation by the operation button 1, abnormalities such as the progress of washing such as washing, rinsing, and the like that cannot be dehydrated. The signal of the display content is output from the control unit 2. The sound generating means 4 (e.g., Myeongdong Kogi, hereinafter same) is a sounding body such as a piezoelectric buzzer that generates sound by the application of an electric signal, and the electric signal is output from the control unit 2. The washing machine mechanism 6 is an eastern part that performs washing operations such as a motor, a clutch, an electromagnetic valve, and the like. The washing machine driving circuit 5 generates driving power of the washing machine mechanism 6 according to a control signal output from the controller 2. The sensor 8 is a series of sensors for measuring information necessary for the control of the washing machine, such as the weight of the laundry, the level of the washing tank, the turbidity of the washing water, the concentration of the detergent, the control unit 2 is the interface circuit to the signal from the sensor 8 Lead through (7).

2 shows an example of the operation button 1 and the display panel 3. The user sets the washing operation by each button below the display panel 3, and starts the washing machine by pressing the start / pause button. If the same button is pressed during operation of the washing machine, the operation of the washing machine is paused, and pressing again resumes the operation. The course button is a button for the user to select a washing course according to the type and quantity of laundry. The course button is selected from the seven courses recorded on the display panel above the button. In the "manual" course, the user sets the washing operation such as washing time, rinsing frequency, etc. by each button. In the "standard" course, the control unit 2 automatically sets the washing operation in accordance with a measurement value such as the weight of the laundry by the sensor 8. Each button of course, quantity, washing, rinsing, and dehydration selects several setting values with one button each.The setting value changes sequentially with each press, and the initial setting value is returned when all the setting values are passed. Go back. The set value is displayed on the display panel 3. Also, the hour and minute buttons increase by one between the hour and minute displays on the display panel 3 each time the button is pressed.

The buzzer button is a button for the user to set the stop of the ringing sound of the sound generating means 4, the volume reduction, etc., if necessary, and the setting state is the upper right of the hour and minute display of the display panel 3. Is indicated by a symbol.

FIG. 3 shows an example of the form of change in the set value by pressing each button of water quantity, washing, rinsing and dehydration. The quantity button sets the water supply amount, the washing button sets the washing time, the rinsing button sets the rinsing frequency, and the dehydrating button sets the dehydration time. When setting to "No setting", respectively, the control part 2 automatically sets each setting value according to the measured value by the sensor 8. As shown in FIG.

At the same time as the user presses the operation button 1, the sound generating means 4 generates short sounds corresponding to each button and each set value. 4 is a flowchart showing the operation of the control unit 2 in the generation of sound by pressing the operation button 1. When the user presses the power button to turn on the washing machine, the control unit 2 displays the initial setting value of each washing operation on the display panel 3, and sets the counter of the setting value to 0 for each button (S- One). When the user presses any button of the operation button 1, the control unit 2 reads a signal by pressing the button (S-2), and first determines which button (S-3). If the button is pressed at that time (S-4), the counter of the set value of the button is increased by one. However, if the settable size is reached with the button, it is reset to zero. For example, in the case of the quantity button, since there are six setting values shown in FIG. 3, the counter is increased to 1 and resets to 0 if it is 6 (S-5). At the same time, the display between the setting value of the washing operation by the button and the setting on the display panel 3 is changed. In the case of the quantity button, since the initial setting value is " automatic (no setting) ", the setting value is changed to " high "

If the setting of the set value is valid at that time (S-7), the control unit 2 calculates and generates a sound signal corresponding to this and outputs it to the sound generating means 4 (S-8). Then, the control unit 2 waits for the operation button 1 to be pressed again.

If the press of the button is invalid (S-4), the control unit 2 calculates and generates a sound signal indicating invalidity and outputs it to the sound generating means 4 (S-9). For example, when the washing course is set to "standard", the washing time is automatically set, so pressing of the washing button is invalid. In addition, even if the button itself is valid, if the set value to be set by the button is invalid (S-7), the control unit 2 calculates and outputs a sound signal indicating invalidity to the sound generating means 4. (S-9). For example, in the case of reserving a washing end time, the user repeatedly presses the hour and minute buttons until the desired reservation time is displayed. As a result, when the difference between the present time and the reservation time being displayed is small and washing is not possible at the reservation time, the reservation time is invalidated and a sound indicating invalid is generated when the hour and minute buttons are pressed. In addition, when some of the settable values settable by pressing one button are invalid, the settable values themselves may be removed as the object of the setting.

In addition, the generation of the sound can be stopped or the volume can be reduced by setting the buzzer button.

5 is an example of a sound generated by pressing each button. These are set to different sounds according to each button and each set value by one button. These are all square waves with constant amplitude. The water volume button continuously raises the frequency of the sound to express the feeling of the water level rising by the water supply. The higher the quantity, the longer the sound generation time and the larger the frequency increase. Also, the volume is attenuated with time in order to make it sound pleasant. The washing button uses two or three melodies, such as `` me, wave, sol, '' and the volume of each melody is attenuated with time.

6 shows an example of waveforms of sound signals generated by button presses. This sound is generated when the washing course is set to "blanket" by the course button, and is written in the bottom column of FIG. This is a two-melody melody with the same feeling as `` pa-sol '', which is 50ms for each note and 100ms in total. The voltage amplitude of the square wave is kept constant at 5V. The period of the square wave in each sound is constant at T ₁ = 0.38 ms (frequency 2.6 kHz) and T ₂ = 0.34 ms (frequency 2.9 kHz), respectively, and voltage is present (5 V) and no (0 V) within one period. The volume is controlled by changing the time ratio of. In order to attenuate the volume with the dismissal note time t in each of the negative voltage causes the τ _1, τ ₂ for the first time _{T 1/2, T 2/} 2 , and the attenuation with time t. In the intermediate time t = 25ms in the first sound is substantially zero in the τ ₁ = T _1/4, and in, the vicinity of one negative end of t = 50ms. The control unit 2 generates and outputs data of a sound signal at a constant sampling period, for example, T _S = 10 μS (frequency f _S = 100 kHz) by digital operation. Since the sound signal is a square wave with a constant amplitude, the voltage oil (5V) is expressed as 1, and the nothing (0V) is expressed as 0. For example, in the first period of the first sound, nineteen ones and nineteen zeros are continuously output.

FIG. 7 is a diagram showing a time variation of the voltage ratio, the time ratio of no voltage, and the volume in one cycle of the square wave in the waveform of FIG. The square wave of waveform value 1 or 0 and period T, and the time of waveform value 1 in one period are made into (tau) (0 <= (tau) / T <= 1). When the square wave is expanded by Fourier series, the amplitude a _n of the nth harmonic becomes a _n = (2 / nπ) · sin (nπ · τ / T). n = 0 is the direct current component, and n = 1 is the fundamental wave component. The amplitude a _n of the AC component that contributes as a negative decreases with the harmonic order n, and the amplitude a ₁ of the fundamental wave component is the maximum. In addition, if the sound generating means 4 such as a piezoelectric buzzer has a narrow reproduction frequency band and can accommodate the frequency of the square wave (the reciprocal of the period T) in the frequency band, only the fundamental wave component contributes as sound. Therefore, the relationship between the time ratio τ / T where the waveform value is 1 in one period of the square wave and the volume v of the generated sound by the sound generating means 4 is approximately v = b · sin (nπ · τ / T) (B is a constant coefficient). Therefore, even if the amplitude of the square wave is constant, it is possible to control the volume by controlling the time ratio between voltages in one cycle.

It demonstrates again with reference to FIG. As the information necessary for the control unit 2 to calculate and generate the sound signal when the operation button 1 is pressed, as shown in the same drawing, in the case of a melody sound such as a washing button, the negative number, the frequency or period of each sound is shown. In the case of continuous rise or fall of frequencies such as the generation time and the quantity button, the frequency and the generation time of both ends may be recorded for each button and each set value. With this information, a sound algorithm can be calculated and created in real time with a simple algorithm. The attenuation of the volume can be obtained by decreasing the voltage significant time tau in one period of the square wave at a constant rate, and the continuous rise or fall of the frequency can be obtained by increasing or decreasing the period of the square wave at a constant rate.

Although the washing machine has been described as an example, the present invention is not limited thereto, and the present invention can also be applied to home telephone apparatuses having a large number of operation buttons such as a microwave oven and a number of setting menus by the same button.

According to this embodiment, since only the simple information such as the frequency and the generation time of the sound is recorded for each button and each set value, and the sound signal is calculated and output in real time, the button is pressed with a small amount of recording data. Each button can produce a different tone depending on its setting. In addition, since the sound signal is a square wave with a constant amplitude, the sound signal can be output to one digital output terminal. In addition, since the volume control is performed by controlling the time ratio between voltage and non-voltage within one period of the square wave, it is possible to generate a variety of sound expressions due to the time variation of the volume and to generate a pleasant volume attenuation type sound. Therefore, even when a visually impaired person who has difficulty in seeing and confirming the display is used, it is possible to execute while confirming the setting of the selection operation by the operation button negatively, and no mistake of pressing the operation button occurs.

8 is a flowchart showing the procedure of the washing process of the washing machine of the present embodiment by the operation of the control unit 2. At the end of each washing process such as washing and rinsing at the start of operation of the washing machine and at the end of washing, the control unit 2 generates a high sound indicating this. Examples of each notice will be described next with reference to FIGS. 9 and 10.

When the user turns on the washing machine and sets the washing operation by the operation button 1, the control unit 2 generates a sound corresponding to each button and each set value every time the button is pressed (t- One). Then, when the user presses the start button, the control unit 2 generates an alarm at the start of washing and starts operation of the washing machine (t-2). The controller 2 executes water supply as the first washing process (t-3), and stops the water supply when the water level of the washing tank reaches a predetermined value (t-4). Then, the control unit 2 executes washing as the next washing step (t-5), and generates a notice indicating this at the end of washing (t-6). Then, the control unit 2 executes the rinsing as the next washing step (t-7), and generates a notice indicating this at the end of the rinsing (t-8). Then, the control unit 2 performs dehydration as the last washing process (t-9), and generates a notice indicating the end of washing at the end of dehydration (t-10).

9 and 10 show one example of the start of washing and the end of water supply. Each sound is longer than the sound generated at the time of the button press so that the user does not hear even when the user is away from the washing machine. The notice at the start of washing is a sound that simply expresses the course or process of washing to be performed in the future. For example, when the washing course is set, the melody sound generated by pressing the course button is extended or the sound generated by pressing each button when the washing operation such as washing is set is performed. To be continuous notes. For example, when the washing course shown in Fig. 9 (a) is set to manual, the 100mS two-tone melody “Do and Le” generated by the button press is shown in Fig. 9 (b). As described above, the five-melody melody of 300 mS is referred to as "do, le, do, le, do-". Alternatively, as shown in Fig. 9 (c), when the quantity is set to "high" and the washing time is set to "12 minutes" in the "manual" course, the amount of water generated by pressing each button is washed, washed and rinsed. , It occurs continuously in the process of dehydration. In addition, when the washing course is "standard" and the control unit 2 automatically sets the quantity and the like, the sound generated when the automatically set quantity and the like are manually set by pressing a button is used.

Similarly, the sound of the end of each washing process is also set to extend the sound generated by pressing a button at the time of operation setting of each washing process. For example, the sound generated at the time of button press when the quantity is set to "high" is 500 mS of the generation time shown in FIG. 10 (a), and continuously rises from a frequency of 2.2 kHz to 5.7 kHz, with a volume attenuation type sound. The lower sound at the end of water supply is the sound extended to 1000mS as shown in the same drawing (b).

The washing machine according to the present embodiment generates an error notification notifying when an abnormality requiring the user's treatment such as impossibility of dehydration occurs during operation. 11 is a flowchart showing the operation of the control unit 2 when dehydration is impossible.

When the control unit 2 tries to start dehydration (t-9), when the lid of the washing tank is opened and the dehydration impossibility due to the deflection of the laundry in the washing tank is detected by a signal from the sensor 8 (u-1) An error message indicating this is generated and the operation of the washing machine is paused. The occurrence time is extended together with the number of occurrences of the notice, and the first time is set to 1 second (u-2). For example, when the user's treatment is executed within a predetermined time of about one minute and the abnormality is eliminated (u-3), the control unit 2 resumes dehydration (t-9).

If the abnormality is not solved within a predetermined time (u-3), the control unit 2 generates an error notification again. The occurrence time is extended from the previous time, for example, 2 seconds (u-4). As in the previous case, when the abnormality is resolved within a predetermined time (u-5), the control unit 2 resumes dehydration (t-9), and when it is not eliminated (u-5), further extends the time. For example, it generates an error notification for 3 seconds (u-6). If the abnormality is resolved within a predetermined time (u-7), the control unit 2 resumes dehydration (t-9), and if it is not resolved (u-7), cuts off the power of the washing machine. According to the present embodiment, while an error occurs and the error is not solved, the error notification is repeatedly generated at a certain time and the occurrence time of the notification is extended for each occurrence, so that even if the user does not hear the error notification, Since the error notification that is not heard is repeatedly generated, the user rarely hears the error notification. In addition, a limit is set on the number of occurrences of the error notification, and when the limit is reached, the washing machine is turned off, so that even if the treatment is not performed due to the absence of the user, Waste can be reduced.

When the washing machine according to the present embodiment determines that there is a lack of detergent or when there is an oversufficiency in a setting value of a washing operation such as a washing time set by the user, a washing machine indicating this can be generated to request the user's treatment. 12 is a flowchart showing the operation of the control unit 2 in the case where it is determined that the detergent is insufficient at the start of washing.

The control part 2 complete | finishes water supply and produces the high pitched sound indicating this (t-4). When it is determined that the concentration of the detergent is insufficient due to the electrical conductivity of the wash water measured by the sensor 8, the light transmittance, and the like (v-1), the control unit 2 generates a high sound indicating this, Pause operation (v-2). When the user adds the detergent and the concentration of the detergent reaches a predetermined value (v-3), the control unit 2 immediately starts washing (t-5). When the detergent concentration does not reach the predetermined value (v-3), the control unit 2 starts the suspension after a predetermined time (v-4) (t-5). According to the present embodiment, since the user is informed of the lack of detergent before washing, the judgment is made. Therefore, if the user forgets to put the detergent and lacks the input of the detergent and wants to wash the water, the washing is performed as it is. There is a number.

13 is another example, in which a flow chart showing the operation of the control unit 2 in the case where the number of rinses set by the user is finished and the residual concentration of the detergent is greater than or equal to a predetermined value, is recommended to the user for further rinsing. to be.

If the user sets the number of rinses twice and the control unit 2 finishes this (t-7), and determines that the detergent concentration of the wash water at this point is more than a predetermined value and that rinsing is necessary again (w- 1), the control unit 2 generates a notice for recommending adding a rinse once (w-2). When the rinse button is operated within a predetermined time (w-3), the control unit 2 immediately starts rinsing (w-5). If the operation of the hang button is not performed within a certain time (w-3), the control unit 2 follows the user's preset setting of whether or not to follow the recommendation (w-4). In case of pouring, a rinse time is automatically added (w-5), and in case of non-pouring, rinsing is immediately terminated to generate a notice indicating this (tB). According to the present embodiment, when it is determined that the rinse is insufficient, the user's treatment is recommended by notification, and when the user's treatment is not performed within a predetermined time, the rinse is automatically added according to the user's preset. If the user does not carry out the treatment, the washing operation is performed according to the user's prior intention, even if the washing time is extended, or the washing time is performed according to the user's scheduled time without extending the washing time. You can choose whether or not to exit.

In addition, by setting the buzzer button, it is possible to stop the generation of the high pitched sound entirely or to limit the volume of the high pitched sound only to the minimum necessary high sound, such as at the end of washing or when abnormality occurs.

FIG. 14 is a flowchart showing the operation of the control unit 2 in the case where the user performs a specific button operation at any point in time during the operation of the washing machine to generate a high sound representing the washing process in progress at that point in time. .

If the user executes a specific button operation such as pressing a course button at any time during the operation of the washing machine (y-1), the control unit 2 determines the washing process currently in progress and the remaining time in the process. do. For example, if the washing time is set to 12 minutes and 8 minutes have passed since the start of washing, it is determined that the remaining time of washing is 4 minutes (y-2). Then, the controller 2 is a sound representing the current washing process and the remaining time in the process, which is generated when the operation time closest to the remaining time of the sound generated when the button for setting the washing operation of the washing process is pressed. Choose a note to play, and this occurs. For example, if the remaining time of washing is 4 minutes, as shown in FIG. 3, the closest setting value of the washing time is 5 minutes, so that a sound when the button is pressed when the washing time is set to 5 minutes is generated. do. Similarly, when the setting of the rinsing frequency is 2 times and the first time is finished and the second time is in progress, the sound when the button is pressed when the rinsing frequency is set to 1 time is generated (y-3).

According to the present embodiment, even a visually impaired person who has difficulty in seeing and confirming the display can know the washing process currently in progress by sound, including the remaining time by rough calculation.

Although the example of the start and end of a process and the notice of an error state were demonstrated using the washing machine as an example, it is not limited to this, A home telephone apparatus, such as a microwave oven, may be sufficient.

Here, a method of correcting the fluctuation of the volume due to the frequency of the sound generating means 4 by using a method of controlling the volume ratio by controlling the time ratio between voltages and zeros in one period of the square wave is performed. It demonstrates, referring FIG. The dotted line in the figure indicates that a square wave voltage having a constant amplitude is applied by changing the frequency to a piezoelectric buzzer widely used as the sound generating means 4 with a fixed time ratio of 1 to 1 in a cycle. This is an example showing the relationship between the frequency of the case and the volume of the piezoelectric buzzer. Since the volume is increased in a narrow frequency band around 2.3 kHz, even when a melody is generated in the scale from the drawing to the sole, the volume fluctuates according to the pitch, resulting in a somewhat unnatural melody sound.

Therefore, by changing the time ratio of the presence / absence of voltage in one period of the square wave according to the frequency, the fluctuation of the volume due to the frequency can be corrected. In the example of the figure, as shown in FIG. 1, the time ratio τ / T with and without voltage in the scale from the diagram to the sole is a frequency characteristic opposite to the volume of the piezoelectric buzzer. The volume of is substantially constant as shown by the solid line in the figure, and can eliminate the fluctuation of the volume due to the pitch.

16 is an explanatory diagram showing another embodiment of the washing machine according to the present invention. The block diagram is the same as in FIG. That is, the operation button 1 is a group of button switches in which the user sets the washing operation such as driving, stopping or time of the washing machine, rinsing frequency, and the like. The control unit 2 is an arithmetic controller that reads the signal from the operation button 1 and executes the operation control of the washing machine in accordance with the signal, and is configured using a commercially available microprocessor or the like. The display panel 3 is a display device which displays the set value of the washing operation by the operation button 1 and the occurrence of abnormalities such as the progress of washing such as washing and rinsing or the inability to dehydrate, and is configured using a fluorescent display panel or the like. . The display content is controlled according to the signal output from the control unit 2. The sound generating means 4 is a sounding body such as a piezoelectric buzzer that sounds when an electric signal is applied, and the electric signal is generated by the controller 2.

The washing machine section 6 is a driving part such as a motor, a clutch, an electromagnetic valve, etc. necessary for performing a washing operation. The washing machine driving circuit 5 generates the driving power of the washing machine mechanism 6 according to the control signal output from the controller 2.

The sensor 8 is a series of sensors that measure information necessary for the control of the washing machine, such as the weight of the laundry, the level of the washing tank, the turbidity of the washing water, the concentration of the detergent, and the like, and the control unit 2 is a signal from the sensor 8. Is read through the interface circuit 7.

Fig. 31 shows an external perspective view of a washing machine employing the present invention. That is, the washing machine has a top cover 21 on the outer frame box 20, a lid 22, and a display operation unit 23 disposed at the front center of the top cover 21. The display panel is integrally arranged and arranged as shown in FIG. In the top cover 21 on the back side of the display operating section 23, the control unit 2, the washing machine driving circuit 5, the interface circuit 7, and the sound generating means 4 are arranged on the same substrate. Moreover, the washing tank, the washing | cleaning mechanism part 6, and the sensor 8 (not shown) are accommodated in the outer frame box.

An example of the display operation unit 23 is shown in FIG.

16 shows an example of the operation button 1 and the display panel 3. Around the display panel 3, the course setting button 1a, which executes the setting of the washing operation, starts the washing machine by pressing it, and starts / stops the operation by pressing it again while pressing it during operation. The pause button 1b and the power button 1c are arranged.

The course setting button 1a is an operation button for the user to select a washing course according to the type or amount of laundry, and selects one of seven courses displayed (formatted) on the display panel 3 above the button. The "manual" course is a course in which a user sets washing operations such as washing time and rinsing frequency with each button. The "standard" course is a course in which the control unit 2 automatically sets the washing operation in accordance with measured values such as the weight of the laundry by the sensor 8. And each button of course, quantity, washing, rinsing, and dehydration is to select several setting values with one button each. When pressing once, the setting value is changed sequentially and the initial setting It is used to return to the value. The set value is displayed on the display panel 3. Incidentally, the hour and minute buttons are used to increase the display value of hours and minutes on the display panel 3 by "1" each time it is pressed.

In addition, when the display and the operation unit are described in more detail, 10 denotes a course display unit, each time the course button 18 is pressed in accordance with the laundry, the washing policy such as standard, blanket, soak, strength, and saving is displayed. (For example, by enclosing the corresponding letter). The time display unit 12 displays the current time, reservation time, and remaining time. The washing content display unit 13 displays the contents and the progress of washing, rinsing, and dehydration. For example, the ongoing process flashes during operation. Denoted at 14 is a detergent amount and quantity display unit, and the detergent cup mark indicates the standard of the detergent amount and also displays the standard of the quantity. Reference numeral 15 denotes a level, which contributes to the arrangement of the main body. Numeral 16 denotes the substance of (1a), which is water quantity, washing, rinsing, and dehydration button. Reference numeral 17 denotes a reservation and time alignment button, and 18 denotes a course button. In the present example, the height of the sound is changed for each button as in the case of doramipa solari, but furthermore, a different melody is sounded at the start and end of each process.

The start / pause button 1b is composed of two buttons, “cold water” and “hot water”. The “cold water” button is supplied with tap water from the beginning to perform washing, and “hot water” is a pump built in a washing machine. It is used to set up to perform washing by receiving remaining hot water of bucket. However, when the rinsing of the finish or the remaining hot water in the bucket is gone, it is automatically switched to the supply of tap water.

The circuit system of the control part 2 and the sound generating means 4 is illustrated in FIG. The control unit 2 is composed of, for example, an 8-bit microcomputer. An operation button, an LED of a display panel or a terminal of a fluorescent display panel, a washing machine driving circuit, and an interface circuit are connected to the input / output terminals of the microcomputer (not shown). The sound generating means 4 is composed of a transistor 27 and a piezoelectric buzzer 25. In a ROM built into the microcomputer, software for generating a signal for driving the piezoelectric buzzer 25 in advance is stored.

When the sound generation process is executed, a square wave having an amplitude of 5 V as shown in FIG. 11 is output to the output terminal 26 of the microcomputer. By the square wave output, the transistor 27 is turned on or off (off). As a result, a square wave signal having an amplitude of 7 V is applied between the positive electrodes of the voltage reducer 25. As a result, the piezoelectric element in the piezoelectric buzzer 25 vibrates due to the electric distortion, and the vibration is radiated into the atmosphere as sound waves. If the square wave signal is 1mS in period, sound waves with a frequency of 1kHz are emitted. The volume can be changed by changing the duty ratio of the square wave signal.

FIG. 17 shows an example of a change in the set value by pressing each button of water quantity, washing, rinsing and dehydration. The quantity button is used to set the water supply, the washing button at the time of washing, the rinse button to set the number of rinses, and the dehydration button to set the dehydration time. "No setting" means that the control unit 2 automatically sets the water supply amount according to the measured value by the sensor 8 for the quantity of water, and omits the process for washing, rinsing and dehydration.

The control unit 2 executes a control in which the sound generating means 4 generates a pop sound corresponding to each button or setting value while the user presses the operation button 1.

FIG. 18 is a flowchart showing the operation of the control unit 2 for ringing the sound generating means 4 in response to the press of the operation button 1. When the user presses the power button 1c to turn on the washing machine, the control unit 2 displays the initial setting value of each washing operation on the display panel 3, and sets the counter of the setting value for each button to &quot; 0 &quot;. (X-1). When the user presses any one of the operation buttons 1, the control unit 2 reads the signal by pressing the button (x-2), and first determines which button (x-3). Then, if the press of the button at that time is effective (x-4), the counter of the set value of the button is increased by "1". However, when the settable value settable by the above button is reached, it is reset to "0". For example, in the case of the quantity button, since there are six setting values, if the counter is increased to "1" to "6", it is reset to "0" (x-5). Next, the setting value of the washing operation by the button and the display of the setting value on the display panel 3 are changed. In the case of the quantity button, since the initial setting value is "no setting (automatic)", it changes to the next setting value "high" (x-6). If the setting of the setting value is effective (x-7) at that time, the control unit 2 calculates and generates a sound signal corresponding to the setting value and outputs the sound signal to the sound generating means 4 to make it sound (x). -8). Then, the controller 2 again waits for a signal lead by pressing the operation button 1.

If the pressing of the button is invalid (x-4), the control unit 2 calculates and generates a sound signal indicating invalidity, outputs it to the sound generating means 4, and makes it sound (K-9). For example, when the washing course is set to "standard", washing time is automatically set, so pressing of the washing button is invalid.

In addition, even if the button itself is valid, even if the setting value to be set by the button is invalid (x-7), the control unit 2 calculates and generates a sound signal indicating invalidity and sends the sound signal to the sound generating means 4. Print it and make it ring (x-9). For example, in the case of reserving the washing end time, the user repeats pressing the hour and minute buttons until the desired time is displayed. In this setting, if the difference between the current time and the reservation time being displayed is small and the laundry cannot be finished by the time until the reservation time, the reservation time is invalidated so that a sound indicating invalid is generated when the hour and minute buttons are pressed. Sounding means (4). In addition, when a part of setting values which can be set by the press of one button is contained, the said invalid setting value itself may be removed as a setting object.

19 shows an example of a sound generated by pressing each button. (Example 1) in the figure shows an example of different sounds for each set value by one button. I am doing it. However, in order to show that it is a reference | standard about an initial setting value, it is set as 2 sound of "FIG. In FIG. 19 (Example 2), each button has a different sound. I am doing it.

The sound of (Example 1) is shown by () in FIG. 17, and the sound of (Example 2) is shown by [] in FIG. However, since the piezoelectric buzzer or the like generally used as the sound generating means 4 has a narrow frequency band, the range of the scale is such that the volume reduction from the maximum volume falls within a predetermined value within, for example, -10 dB. For example, it should be within 1 octave. For example, since the minute buttons in Fig. 16 have 60 types of setting values by one button, ranging from 0 to 59 minutes, the sound generated at the time of button press is not made different from the whole set value. 0 minutes is "degree" and "10" units other than 0 minutes are set to "me", and other than "re".

20 shows an example of a waveform of a sound signal generated in response to a button press. This example is a sound generated when the washing course is set to "standard" by the course button. This is a three-note sound of "do-do" with a short silence, which is 210mS in total with 100mS of sound each and 10mS of silence. The sound signal is a square wave whose amplitude is constant, and whose amplitude is 5V and the period T = 0.48mS (frequency 2093Hz). The time ratio of voltage high (5V) and low (0V) in one cycle shall be 1: 1. The control unit 2 generates and outputs data of a sound signal at a constant sampling period, for example, T _S = 10 μS (sampling frequency f _S = 100 kHz) by calculation. The negative signal expresses the voltage high (5V) as "1" and the low (0V) as "0". Therefore, the control unit 2 alternately outputs 24 "1s" and the same number of "0" s during 100mS of the first sound, and continuously outputs "0" as silent during 10mS of the second sound, During the 100mS of the third sound, the same data as the first one is output.

Again, return to the description with reference to FIG. When the operation button 1 is pressed, the control unit 2 calculates and generates a sound signal, and as information necessary for outputting the sound signal, the negative number, the frequency and period of each sound, and the occurrence time are recorded as shown in the same drawing. It is good to keep. The control unit 2 can calculate and generate a sound signal in real time based on these information.

As described above, according to this embodiment, since the sound corresponding to each button and the set value can be generated when the operation button 1 is pressed, the user is assured that the setting of the washing operation is accepted reliably. Particularly, for the visually impaired who has difficulty in seeing and confirming the display, the setting of the washing operation can be performed without fail while confirming negatively. If only basic data such as sound frequency and generation time are recorded and maintained for each generated sound, the control unit 2 can calculate and output a sound signal in real time according to the basic data. Volume can generate many kinds of sounds according to each button and setting value. In addition, instead of calculating and producing a sound signal in real time at the time of pronunciation, the control unit 2 records waveform data of the sound signal itself so that the control unit 2 reads and outputs the waveform data sequentially when sound is generated. good.

Next, an operation of generating a high noise when the washing machine finishes washing or when an abnormality occurs is described. 21 is a flowchart showing an operation performed by the controller 2 in accordance with the progress of the washing process of the washing machine. The control unit 2 executes the control for causing the sound generating means 4 to ring loudly so as to generate a high sound indicating this at the start of operation, at the end of each washing process such as washing and rinsing, and at the end of washing. Examples of each notice are shown in FIGS. 22 and 23.

When the user inputs the power button 1c of the washing machine and sets the washing operation by the operation button 1a, the control unit 2 generates a sound corresponding to each button and the set value every time the button is pressed. The sound generating means 4 is controlled (z-1). When the user presses the start button 1b, the control unit 2 controls the sound generating means 4 so as to generate a high noise at the start of washing, and starts operation of the washing machine (z-2). The notice sound is made different when the "cold water" is pressed in the start button 1b and the "hot water" is pressed. The controller 2 executes water supply as the first washing process (z-3), stops the water supply when the level of the washing tank reaches a predetermined value, and controls the sound generating means 4 to generate a high sound of the end of the water supply. (Z-4). Then, washing is performed as the next washing step (z-5), and the sound generating means 4 is controlled to generate a high sound indicating this at the end of washing (7-6). Then, rinsing is performed as the next washing step (z-7), and the sound generating means 4 is controlled to generate a high sound indicating this at the end of the rinsing (z-8). Then, dehydration is performed as the final washing step (z-9), and the sound generating means 4 is controlled to generate a high sound indicating the end of washing at the end of the dehydration (z-10). In addition, when the start button 1b is pressed during the washing operation, the control unit 2 controls the sound generating means 4 so as to generate a sound for a short time, and temporarily stops the operation of the washing machine, and then the start button 1b is pressed again. Operation is resumed by controlling the sound generating means 4 so as to generate a high pitch of the washing machine. The short-time sound is, for example, a two-point sound with a 10 mS silence between two 100 mS sounds, such as "Sol and Sol". In addition, the notice of the said washing | cleaning reconnection may be the same as that of the said washing start, and may differ.

Similarly to the sound generated when the button is pressed, only the basic data such as the frequency and duration of the sound are recorded and maintained for the high pitched sound, and when the high pitched sound is generated, the control unit 2 generates a sound signal according to the basic data. Compute and output in time. The waveform data of the high pitched sound may be recorded so that the waveform data is sequentially read out at the time of generating the high pitched sound.

22 shows an example of a high note occurring from the start of washing to the end of washing. Each notice sound is longer than the sound generated at the time of button press so that the user does not hear even when the user is away from the washing machine. And, in order to express the progress of the washing, when the high notes are connected to each other in the order of the washing process, the music with a friendly feeling that matches the preference is configured. The example in FIG. 22 is a double version of the "joy of joy" in Beethoven's ninth symphony. As a result, the first two measures at the start and restart of the washing, the third and fourth measures at the end of the water supply, the 5th and 6th measures at the end of the washing, and the seventh and eighth measures at the end of the rinsing for 4 seconds. Doing. At the end of the laundry, the occurrence time is extended so as not to be heard in particular, so that it occurs for 16 seconds after the 9th measure. In addition, when two notes of the same pitch are continued like the first part, a silence of about 10mS is inserted in between so as not to be heard as a long continuous note.

FIG. 23 shows another example of the high pitched sound. This is a combination of two French folk songs, "On the Bridge of Avignon" and "The Bells". When the "cold water" of the start button 1b is pressed, the former is generated, and when the "hot water" is pressed, the latter is generated as a notice. In this example, the notice is generated at the start of washing, resumption, and termination, and no notice is generated at the end of the process. At the start of washing, the first two measures, the third and fourth measures are generated for four seconds each, and at the end of washing, the first two measures are generated for eight seconds.

According to this embodiment, since the high sound corresponding to the washing operation to be executed in the future such as cold water and hot water is generated at the start of washing, the user can confirm by sound that the intended washing operation is performed, and in particular, even if the visually impaired You can run the laundry without this. In addition, by generating familiar pieces of music in order from the beginning in order to suit the progress of washing, the user can know the progress of washing by himself even if he is away from the washing machine. Although this embodiment has been described for the case where the high sound is generated at the end of each step of the washing operation, the high sound during washing may be omitted so that the high sound is generated only at the start and end of the washing or only at the end of the washing.

The washing machine according to the present embodiment generates an error notice informing the user when an abnormality that requires the user to intervene during operation such as impossibility of dehydration occurs during operation. 24 is a flowchart showing the operation of the control unit 2 in the case where a non-dehydrated state occurs.

When the control unit 2 intends to start the dehydration process (z-9 in FIG. 21), the control unit 2 detects an inability to dehydrate by the opening of the lid of the washing machine or the washing of the laundry in the washing tank by a signal from the sensor 8. In the case (d-1), the sound generating means 4 is controlled so as to generate an error notifying notifying this, and the operation of the washing machine is temporarily stopped. This notice makes a sound with a sense of urgency to show an abnormality, for example, "midomi" ”, So that two sounds of about 100mS are generated continuously. This notice shall be extended with the number of occurrences, and the first time shall be 1 second (d-2). For example, when the user's treatment is executed within a predetermined time (1 minute) and the abnormality is solved (d-3), the control unit 2 resumes dehydration (z-9). If the abnormality is not solved within the predetermined time (d-3), the control unit 2 controls the sound generating means 4 to generate an error notification sound again. At this time, the generation time is extended from the previous time, for example, for 2 seconds (d-4). As in the previous time, when the abnormality is resolved within the predetermined time (d-5), dehydration is resumed (z-9), and when not resolved (d-5), the time is further extended, for example, for 3 seconds. The sound generating means 4 is controlled to generate an error notification of (d-6). If the abnormality is resolved within the predetermined time (d-7), dehydration is resumed (z-9), and if it is not resolved (d-7), the power source of the washing machine is cut off (d-8).

According to this embodiment, while the abnormal state occurs and this is not solved, the error notification is repeatedly generated at a certain time, and the occurrence time of the notification is extended for each occurrence, so that the user cannot hear the error notification. In this case, since the error notification can be generated with almost no hearing, the error notification hardly occurs. In addition, a limit is set on the number of occurrences of the error notification, and when the limit is reached, the washing machine is turned off, so that even if no action is taken due to the absence of the user, the waste or power of the surroundings due to the error notification is prevented. Waste can be reduced.

Next, a method of increasing or decreasing the volume by a square wave having a constant amplitude will be described. FIG. 25 is a diagram showing the relationship between the high and low time ratios of the waveform values and the volume in one period of the square wave. In a square wave of amplitude 1 and period T, the time at which the waveform value in one cycle is accumulated is τ (0 ≦ τ / T ≦ 1). If the square wave is expanded by Fourier series, the amplitude an of the nth harmonic is

an = (2 / nπ) sin (nπ · τ / T)

It becomes n = 0 is a direct current component and n = 1 is a fundamental wave component. The amplitude an of the AC component that contributes as a negative decreases with the harmonic order n, and the amplitude a1 of the fundamental wave component is maximum. A general piezoelectric buzzer or the like widely used as the Myeongdong Gorge 4 has a narrow reproduction frequency band. Therefore, when a fundamental wave component is included in the reproduction frequency band, harmonic components of n = 2 or more are out of the frequency band, Contributing almost consists only of fundamental wave components. Therefore, the relationship between the time ratio τ / T in which the waveform value in one period of the square wave is high and the sound pressure level v of the sound generating means 4 is approximately v = b · sin (nπ · τ / T) ( b is a constant coefficient), even if the amplitude of the square wave is constant, the volume can be increased or decreased by increasing or decreasing the time ratio of the waveform value in one cycle.

The sound signal is a high and low binary square wave of the waveform value and increases or decreases the volume ratio by increasing or decreasing the time ratio of the waveform value within one period of the square wave, so that the control unit 2 outputs one digital output. Since the sound signal can be output by the terminal, no analog variable voltage generating means is required.

Next, the operation of the control unit 2 for stopping or resuming the generation of the button operation sound or the high pitched sound or changing the volume by the above method by the specific operation of the operation button 1 is shown in the flowchart of FIG. A description will be given with reference to FIG. In this embodiment, when an operation button other than the power button 1c is continuously pressed in the operation button 1 for a predetermined time or longer, sound generation is stopped, resumed, and volume change is executed.

In the case of the course setting button 1a, the button operation sound is targeted, and in the case of the start / pause button 1b, the high sound is targeted. The loudness of the sound generated is three stages of large, small, and stop, and the large and small time ratios τ / T in which the waveform values in one cycle of the square wave are high are 0.5 and 0.25, respectively. Therefore, the volume change pattern has four types shown in the lower part of FIG.

The control unit 2 executes the initial setting described with reference to FIG. 18 when the user inputs the power button 1c of the washing machine. At this time, each volume change counter for the button operation sound and the high tone sound is set to the value previously set. If the previous set value is not maintained due to a power failure or the plugging and unplugging of the power plug, the reset value is reset to "0" (x-1 in FIG. 18). When the user presses the operation button 1, the control unit 2 reads the signal by the button press (x-2 in Fig. 18), and discriminates the pressed button (x-3 in Fig. 18). Control the sound generating means 4 to generate a sound according to the button and the set value (from x-4 to x-8 or x-9 in FIG. 18). For example, if it does not continue for a predetermined time of about 2 seconds, the control unit 2 returns to the standby state of the button press signal wait. If it continues for more than a certain time (a-1), the control part 2 produces | generates the expression sound of the volume change as shown in FIG. 13 according to the pattern of volume change, and increases the value of the said volume change counter by "1". Let's do it. However, when the original value is "3", it resets to "0". Then, the volume is changed or sound generation is stopped. The volume is changed by changing the time ratio τ / T in which the waveform value in one square wave period is high as shown in the lower part of FIG. For example, when changing from large to small, the ratio is changed from 0.5 to 0.25. In the case of stopping the generation of sound, the output of the sound signal itself is stopped (a-2). If the user keeps pressing the same button even after the sound of the volume change expression is finished, the user is instructed to execute the volume change from the stop to the stop or the stop to the stand, and the value of the volume change counter is "1". Alternatively, in the case of "3" (a-3), the expression sound of the volume change is generated, and the value of the volume change counter is increased to "1" or reset to "0". In the same manner as above, the volume is changed or sound generation is stopped (a-4). Then, it waits to wait for the pressing of the operation button 1 again.

FIG. 27 shows an example of the expression sound of volume change. The frequency is 2 kHz, the generation time is 1 second, and the volume is increased or decreased in accordance with the volume change pattern. For example, if the volume change pattern is large to small, the first 0.2 seconds of the volume is set to the volume band and the last 0.2 seconds to be the volume level, and the volume is continuously decreased from the large to the small level for 0.6 seconds. . The waveform of the sound signal in this case is shown in the lower part of the same drawing. If the sampling cycle is set to 10 µS, one cycle consists of 50 data at 2 kHz. For the first 0.2 seconds, the ratio of "1" and "0" data in one cycle is 25:25, the last 0.2 seconds is 12:38, and the number of "1" data is 25 to 12 for 0.6 seconds in the middle. To decrease continuously. Therefore, at the time of 0.5 second, the ratio of "1" data and "0" data is 19:31.

In this embodiment, it is possible to stop, resume or change the volume of the button operation sound and the high sound by the specific operation of the operation button 1, so that it is not necessary to add new operation means for performing this operation. Do not.

In addition, since the sound that continuously increases or decreases from the volume before the change to the volume after the change at the time of volume change is generated as the expression sound of the volume change, the user can realize what volume change has been performed.

Next, the operation of the control unit 2 in the case of switching the allocation of the generated sound at the time of button operation by the specific operation of the operation button 1 will be described with reference to the flowchart of FIG. In this embodiment, as shown in Fig. 19 (Example 1), ascending scale in order of the set value by one button, or as shown in Fig. 19 (Example 2), ascending scale in order of each button arrangement It is assumed that the switching is performed.

When the user continuously presses two buttons of the operation button 1 simultaneously for a predetermined time or more, the control unit 2 executes the above switching process. When the user presses the operation button 1, the control unit 2 controls the sound generating means 4 to generate a sound according to the button and the set value (x-8 or x-8 in FIG. 18). Up to -9). If the button press does not continue for a predetermined time, for example, about 2 seconds (a-1 in Fig. 26), the control unit 2 returns to the standby state of the button press again. If it continues for a predetermined time or more (Fig. 26-1), if there is only one button, the volume change operation shown in Fig. 12 is executed, and if two buttons are simultaneously, Fig. 28 (b-1) The above switching is executed (b-2). Then, the apparatus waits for the operation button 1 to be pressed again.

Next, refer to the flowcharts of FIGS. 29 and 30 for the operation of the control unit 2 in the case of selecting a note to be used by the user from among several melodies and registering a melody created by the user and adding it to the selector. Explain. This embodiment selects and registers a melody by continuously pressing three or more buttons other than the power button 1c of the operation button 1 simultaneously for a predetermined time or more. An example of the notice of the end of washing will be described.

The control unit 2 executes the initial setting described with reference to FIG. 18 when the user turns on the washing machine. At this time, the button operation sound and the melody are the last set values. If the previous set value is not maintained due to a power failure or the like, it is reset to "0" (x-1 in FIG. 18). If the operation button 1 is pressed, the control unit 2 controls the sound generating means 4 to generate a sound according to the button and the set value (x-8 in FIG. 18 or x-8 or x). Up to -9). Then, when the pressing of the operation button 1 does not continue for a predetermined time of, for example, about 2 seconds, the control unit 2 returns to the standby state of waiting for button pressing. If the pressing continues for a predetermined time (a-1 in Fig. 26), the number of simultaneous button pressing is determined (c-1). In the case of one, the volume change processing of the button operation sound and the high pitched sound is executed. In the case of two simultaneous operations, the button operation sound is switched. In the case of three or more simultaneous melody numbers, "1" is increased. However, if it is a final value, it resets to "0". Then, the melody sound of the number is generated, and the melody sound is selected as the note sound. Here, the melody of the final number is a melody registered by the user. Therefore, in the case of non-registration, a pop such as "beep, beep" indicating non-registration, instead of the melody sound, performs control to generate a sound (c-2). If the new melody number is not the final value, the controller 2 waits again to wait for the operation button 1 to be pressed.

If the final value (c-3), the user can register the melody created by the user. In this state, the user plays and inputs the melody created by the user by the operation button 1 to perform registration. First, the allocation of the sound generated when the operation button 1 is pressed is switched so as to be a rising scale in the arrangement of the buttons as shown in, for example, FIGS. 16 and 19 (Example 2). This allows the user to execute the melody performance input using the operation button 1 as a keyboard (c-4). However, if the button is not pressed at all within a certain period of time, for example, about 3 seconds (c-5), the registration of the melody is canceled and the sound allocation at the time of button press is returned to its original state. . In this case, the melody registered last time or the unregistered melody is selected as the notice (c-6). If the simultaneous pressing of three or more buttons continues for a predetermined time of about 2 seconds (c-7), the melody registration is not executed and the melody of the next number is shifted. Therefore, the melody number returns to "0". If the press is within a certain time, the measurement of the playing time is started with the time at which the button is first pressed as the starting point of the playing (c-8). And every time the signal of a button press is read, control of the sound generating means 4 is performed so that the sound of the pitch allocated to the said button is produced | generated. Thereby, the user can perform the melody input operation in the sense of playing the keyboard musical instrument (c-9). The control unit 2 encodes and records the pitch and the time of pressing allotted to the buttons simultaneously pressed. The time without button press is a comma and records the time and the sign indicating silence (c-10). If the playing time reaches a certain threshold, for example, about 10 seconds, or when the button is not pressed for a certain time, for example, about 3 seconds (c-11), the melody recorded above is recorded as the end of the performance. Perform playback. Here, the user checks whether or not the intended melody could be registered (c-12). If the user wants to re-enter the performance input for a performance failure, for example, the user starts the recording within a predetermined time of, for example, about 3 seconds, and the control unit 2 executes pressing the button within the predetermined time (c-13). , Record the melody again. If the button is not pressed for more than the predetermined time (c-13), as the end of the registration of the melody, the allocation of the sound generated at the time of the button press is returned to its original state (c-14) and waits for the button to be pressed again. do.

In this embodiment, the notification of the end of washing is selected and registered. However, the selection and registration of other notes can also be executed by the same operation. In addition, although the number of melody registrations of a user is set to one, you may make it possible to register several melodies as needed.

According to this embodiment, since the selection and registration of the notice sound can be executed by the specific operation of the operation button 1, it is not necessary to add new operation means for executing this. Also, the sound generated when the operation button is pressed is assigned to the rising scale in the arrangement of the buttons, the information of pressing the button is assigned to the rising scale in the arrangement of the melody, and the information of the pressing of the button is assigned to the melody. As the information is pronounced and recorded, the user can register while confirming the high notes created by the user with the sense of playing the keyboard musical instrument.

According to the present invention, when the operation button of the home telephone is pressed, a different sound is generated according to each button and each set value, so that even if a visually impaired person who has difficulty in seeing and confirming the display is negatively confirming the setting of the device operation by the button, It can be run without fail. In addition, at the end of the device operation or when an abnormality occurs, the sound is also notified at the end of each process of the device, so that even a visually impaired person or a user away from the device can grasp the progress of the device by sound. In addition, when a user-set setting value such as lack of detergent or rinsing frequency causes excessive shortage of the operation of the device, the device is notified to the user negatively and the user's operation is temporarily waited. The failure of the operation can be eliminated.

In addition, the generation of sound can be stopped by the user's setting or limited to the minimum necessary, such as the sound of the end or abnormality, or the volume can be reduced. There is no harm.

In addition, since only basic data such as frequency and generation time of sound are recorded as data for generating sound, and a sound signal is calculated and produced in real time according to this, various sounds can be generated with a small amount of data. Since the sound signal is a square wave with a constant amplitude, and the volume is controlled by a high and low time ratio between waveforms within one cycle, a single digital output terminal can generate a variety of sounds with volume changes.

In addition, according to the present invention, since different sounds are generated depending on each button and each set value at the time of button operation of the washing machine, the user can be assured that the setting of the washing operation by the button operation is correctly accepted. In particular, even a visually impaired person who has difficulty seeing and confirming the display can operate the washing machine without fail.

In addition, when a washing operation is finished or an abnormality occurs, a melody or the like can be generated at the end of each process in operation, if necessary, so that the progress of the washing operation can be grasped by sound even when the user is away from the washing machine. There is. Moreover, if the said high pitched sound is made into the characteristic sound for washing machines, a user will not be confused with the high pitched sound of another apparatus.

In addition, since the sound signal of the generated sound is a square wave having a constant amplitude and increases or decreases the volume by increasing or decreasing the time ratio of the waveform value, only the output signal using one digital output terminal is used without using a voltage variable terminal. You can increase or decrease the volume. In addition, since the volume increase / decrease setting, the stop and resume of sound generation can be performed by the specific operation of the operation button already set, it is not necessary to provide new operation means for volume increase or decrease.

In addition, as the sound generated at the time of button operation, ascending scales such as the dome pasol are assigned in the arrangement order of the operation buttons, and the information of each button press is read back to the assigned pitch and recorded, so that the user can feel the keyboard musical instrument. You can register your own melody.

As the data for generating the sound, basic data such as the frequency and the generation time of the sound are encoded and recorded, and the sound signal is calculated and produced in real time according to these data, so that various sounds can be generated with a small amount of recording data. have.
