Description

  The present invention relates to a dishwasher for washing dishes, and more particularly, to a dishwasher in which the state of operation and operation is notified by sound.

A dishwasher of this type is already known as illustrated in FIG. 7 (see, for example, Patent Document 1). This thing has doors b and c which open up and down, for example in the opening of the front of main part a containing a washing tub. The doors b and c are opened and closed in conjunction with each other by operating a handle d provided on the lower door b. By closing the opening with the doors b and c, the cleaning tank is sealed, and the nozzles at various places where the cleaning liquid is supplied by the pump sprays the cleaning water in various directions to prevent water leakage. For this reason, if the doors b and c are closed abnormally, water leakage cannot be prevented. Therefore, Patent Document 1 provides detection switches e and f that detect the opening and closing of the doors b and c at the left and right positions of the lower door b to detect the opening and closing of the door, and the door closed state is abnormal. Is disclosed, and the contents of the notification can be notified by the difference in the number, interval, and length of the notification sounds. Patent Document 1 describes that the notification means is a piezoelectric buzzer and may be replaced by a speaker or a light emitting diode, and that the response is more reliable than the case where an abnormality is detected by a single detection switch.
JP 2000-325289 A

  By the way, when notifying according to the open / closed state of the door with sound using a piezoelectric buzzer and a speaker, it may be difficult to hear depending on the user or the environment such as sound notification or operation sound in other equipment. is there. In this aspect, the louder the notification sound is, the easier it is for the user to notice and the easier it is to understand. On the other hand, if the notification sound is loud, it will interfere with sound notification on other devices, but even users who have relied on the initial sound notification will become accustomed to using it, and it will be easier to notice the sound notification. In the end, it may be annoying and annoying to get used to the sound notification before the sound notification is required.

  However, if the sound notification in the same state is performed at any time like the one described in Patent Document 1, it is not possible to cope with the difference in necessity and desire for sound notification depending on the time and the case as described above.

  Moreover, even if it is going to notify the content simultaneously with alerting | reporting by the difference in the number of sound alerting | reporting with a piezoelectric buzzer, a speaker as described in patent document 1, the number and interval, time, the blinking number of light alerting by a light emitting diode, and time, etc. It is difficult to understand and the user needs to get used to knowing the contents. Such a problem becomes more serious as the content of the notification becomes plural.

  A first object of the present invention is to provide a dishwasher that is easy to use and is less dissatisfied, which can respond to different demands and desires for sound notifications depending on time and circumstances. To make it easier to understand by voice.

  In order to achieve the above object, the dishwasher of the present invention has sound notification means, volume switching means for switching the volume of notification by the notification means, and volume display means for displaying the switched volume. When the volume switching means is operated, the volume display means displays that the volume switching start state is displayed. After that, when the volume switching means is operated, the display state of the volume display means is changed and the volume switching means One feature is that control means for switching the volume for receiving and notifying the volume switching is provided.

  In such a configuration, when the operation of the volume switching means is operated when the notification means notifies the operation or operation state with the sound of the volume displayed by the volume display means, the control means causes the volume display means to Display the switching start state and notify the user, and by the operation of the volume switching means thereafter, the control means changes the display state of the volume display means and notifies the user that the volume switching time is reached. On the other hand, the volume to be notified is changed upon receiving the volume switching.

  Further, the dishwasher of the present invention has sound notification means, volume switching means for switching the volume of notification by the notification means, and a display element for displaying the volume. When the volume switching means is operated, the display element Another feature is that a control means for switching the sound volume for flashing is provided.

  In such a configuration, the control means causes the display element to blink when there is an operation of the volume switching means, although the notification means notifies the operation or operation status with the sound of the volume displayed by the volume display means. The volume is switched while notifying the user to that effect.

In a further configuration, there are a plurality of display elements, and the control means changes the display elements that are turned on according to the volume.
The control means turns on the plurality of display elements in accordance with the volume, so that the user can be clearly notified of the switching state of the plurality of volumes.

When the volume switching operation is “volume off”, the control means turns off the display element and
In a further configuration that switches to `` sound cut '',
Since the control means turns off the display element in response to the volume switching operation of “volume off”, while clearly informing the user that the volume is switched off due to the difference from the lighting status at the time of sound notification Switching to “sound cut” can be performed.

The notification means notifies the switched volume by voice, and in a further configuration,
Since the notification means notifies the switched volume by voice, the difference in the switched volume can be clearly notified by the user.

When switching to another volume during the voice notification of the switched volume, the control means interrupts the voice notification of the current volume and notifies the voice of the switched another volume.
When the volume switched by the notification means is informed, if the control means is switched to another volume, the control means interrupts the voice notification of the volume at that time, and notifies the voice of the switched another volume. The sound volume can be notified in real time for the sound volume that is switched each time regardless of the sound volume notification during the previous switching.

The control means includes notification data in which the audio data corresponding to the switched volume, the non-voice data corresponding to the waiting time for enabling the volume switching, and the audio data corresponding to the switching being enabled are continuously provided. In a further configuration for performing notification of the switched volume by reading,
When switching to another volume in the middle of notifying the volume switched by the notification means, the control means interrupts the notification of the volume at that time and is switched to notify about the switched another volume. Switching is performed by reading out and using notification data in which voice data corresponding to the selected volume, non-voice data corresponding to the waiting time for enabling the volume switching, and voice data corresponding to the switching being enabled are read and used. The voice notification when switching is enabled when the waiting time has expired can be achieved by one notification data read out once while the response to the interrupting switching of the voice notification by the next switching operation before the elapse of time before becomes effective.

When the control means is not operated for a predetermined time after the sound volume switching means is operated, the control means notifies the sound that the change is set for the sound volume being switched at that time.
Since the next operation is not performed for a predetermined time after the previous switching operation by the volume switching means, the control means notifies the user of the volume so that the volume by the previous switching operation is set to be valid. At the same time as switching the volume, you can clearly announce the volume.

Notification is performed at the switched volume.
Since the notification volume at the time of the volume switching operation by the volume switching means is performed at the switched volume, the voice notification can be performed while making the user feel the switched volume.

When the volume switching is “volume switching”, the volume switching notification is performed at any volume that can be switched by the volume switching means.
Even when the volume switching by the volume switching means is “Volume off”, the user is informed that the switch to “Volume off” has been made by notifying at any volume that can be switched by the switching means. Can be notified.

  According to one feature of the dishwasher of the present invention, in order to notify the operation or operation state at the volume displayed by the volume display means, the repeated operation of the volume switching means is performed by a change in the display of the volume display means. While notifying the user of the distinction between the switching start state and the switching point without any special notification means, the volume can be switched accurately, and the volume can be easily and accurately switched according to the desired and environment. It is possible to provide a dishwasher that is easy and does not cause dissatisfaction due to excessive volume.

  According to another feature of the dishwasher according to the present invention, the volume of the operation or operation is notified by flashing the display element when there is a volume switching operation, while the volume display means displays the volume. The volume can be switched easily and accurately according to the user's wishes and environment so that the user can switch the volume without blinking the display element. It is possible to provide a dishwasher that is easy and does not cause dissatisfaction due to excessive volume.

  By turning on the plurality of display elements according to the volume, it is possible to clearly notify the user of the switching state of the plurality of volumes and to make it easier to use.

  By turning off the display element in response to the volume switching of “Volume off”, the user is clearly informed and notified of the “Volume off” switching state, and the user will not be notified of the sound thereafter. You can avoid anxiety and distrust.

  By notifying the switched sound volume by voice, the user can be clearly notified, and a dishwasher that is easy to use can be provided.

  When the switched volume is informed, if the volume is switched to another volume, the sound notification of the volume at that time is interrupted and the sound notification is made for the switched another volume. Although it takes time, the notification of the volume that can be switched each time can be notified to the user in real time without being affected by the volume notification at the time of the previous switching, and there is no confusion that the switching operation and the corresponding voice notification will shift in time It can be easy to use.

  When switching to a different volume while reporting the switched volume, the sound corresponding to the switched volume is interrupted to notify the switched volume and notify the switched volume. It can be dealt with by simple data processing using read-out notification data in which data, voiceless data corresponding to a waiting time for enabling volume switching, and voice data corresponding to the switching being enabled are continuous. . Therefore, the cost can be reduced.

  Since the setting to enable switching when the next operation is not performed for a predetermined time after the previous switching operation is performed with audio notification to the user, the user is advised about the volume switching setting delayed from the time of the last switching operation. A dishwasher that can be run without confusion and is easy to use can be provided.

  The notification volume at the time of the volume switching operation is performed at the switched volume, and the switched volume can be switched easily and accurately while making the user feel the switched volume.

  Even when the volume is switched to “Volume off”, the user is informed at any volume that can be switched by the switching means, and the user is anxious and distrustful that no further sound or voice notification will occur. You can avoid things like hugging.

  Hereinafter, a dishwasher according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6 to provide an understanding of the present invention. Note that the following description is a specific example of the present invention and does not limit the contents described in the scope of claims.

  The dishwasher according to the present embodiment has the basic configuration as described above, and has a washing tank 2 for storing and washing dishes in the main body 1 shown in FIG. An opening 1b having a door 1a for taking in and out of the cleaning tank 2 is provided. When the door 1a is closed, the hook piece is elastically engaged with the engaging portion provided around the opening 1b so that the door 1a is locked in the closed state. When the door 1a is opened by operating the handle, the lock is automatically performed. It is to be released. The washing tank 2 is supplied with washing water from the water supply valve 3 and accumulates at the bottom. The washing water stored at the bottom of the washing tank 2 is supplied to a washing nozzle (not shown) provided in the washing tank 2 by the washing pump 4 and is ejected from the washing nozzle toward the dishes stored in the washing tank 2. To do. There is a water level detection means 10 at the bottom of the cleaning tank 2 to detect the water level in the cleaning tank 2 and output it as an electrical signal. On the other hand, a heater 5 is disposed at the bottom of the cleaning tank 2 to heat the cleaning water and enhance the cleaning effect of the cleaning water. In conjunction with this, a temperature detection means 9 such as a thermistor (not shown) attached to the bottom of the cleaning tank 2 from the outside is provided, and the water temperature of the cleaning water and the temperature of the cleaning tank 2 are detected by heat conduction. Used for temperature control. A drainage pump 6 that discharges cleaning water in the bottom of the cleaning tank 2 and a blower fan 7 that sends steam in the cleaning tank 2 out of the main body 1 from the exhaust port and dries the dishes after cleaning are also around the cleaning tank 2. Is provided. In the main body 1 around the opening 1b, door opening / closing detection means 8 for detecting opening / closing of the door 1a is provided. The main body 1 also drives the water supply valve 3, the washing pump 4, the heater 5, the drainage pump 6, the blower fan 7, etc. via the load control means 11, and sequentially controls each step of washing, rinsing and drying. Built in.

  For such control, an operation panel 13 as shown in FIG. 2 is provided on the front surface of the main body 1 below the door 1a. The operation panel 13 includes a power-on switch 14 for turning on / off the power, a power-off switch 15, a start switch 16 as a start input means for starting and pausing, a course switch 17 for setting a course, and a drying switch. Input means 21 provided with a drying switch 18 and the like for setting time, and operation display means 22 for performing display according to those operations using LEDs or the like are provided.

  The control device 12 is constituted by a microcomputer or the like, and the load control means 11 is selected according to the input set by the input means 21 and the input information from the door opening / closing detection means 8, the temperature detection means 9, and the water level detection means 10. The load such as the water supply valve 3, the cleaning pump 4, the heater 5, the drainage pump 6, and the blower fan 7, the operation display means 22 such as LED, and the notification means 31 are controlled in accordance with a predetermined sequence. The notification means 31 is normally operated when a closing abnormality detected by door opening / closing information from the door opening / closing detection means 8, a water supply abnormality or drainage abnormality detected by water level information from the water level detection means 10, or an operation end. For these reasons, an abnormality detection means 32 for determining and detecting an abnormality is provided as an internal function of the control device 12. The load control means 11 and the control device 12 are supplied with the power generated by the power circuit 133.

  Here, an outline of a series of operations of the dishwasher as described above will be described. When the user places dishes in the dish basket and stores them in the washing tub 2, puts detergent, closes the door 1a, and starts operation by operating the power switch 14 and the start switch 16, first the washing tub 2 Tap water is supplied from the water supply valve 3 until the water level detecting means 10 detects a predetermined water level at the bottom of the water supply valve 3. The cleaning pump 4 and the heater 5 are energized, and the cleaning water is jetted from the cleaning nozzle toward the dishes by the cleaning pump 4 while being heated.

  At this time, the temperature detection means 9 detects the temperature of the cleaning water, and the control device 12 always knows the temperature of the cleaning water. When the temperature of the cleaning water reaches a predetermined temperature, or when a predetermined time has elapsed from the start of cleaning, the control device 12 ends the cleaning process, energizes the drain pump 6 and temporarily drains the cleaning water.

  Next, tap water is newly supplied and drained by performing the same operation as the above-described washing process for several minutes. After repeating this rinsing process several times, an operation similar to a cleaning process called a heating rinsing process is performed, and when a predetermined temperature is reached or when a predetermined time elapses, this is finished and drained. Finally, the blower fan 7 is operated to discharge the steam in the cleaning tank 2 to the outside of the apparatus, and at the same time, the heater 5 is energized to heat the dishes and dry the attached water droplets.

  In such a configuration, instead of using a simple buzzer sound or LED in the past to operate the notification means 31 at the time of abnormality detection by the abnormality detection means 32 or when the operation is completed, this embodiment is implemented. In this embodiment, as shown in FIG. 1, as the notification means 31, a voice notification means 31a, a melody notification means 31b, and a buzzer notification means 31c are provided so that notification by "voice", "melody", and "buzzer" can be performed. In addition, the input means 21 is provided with notification switching means 33 for switching between “speech”, “melody”, “buzzer” or “off” for these notifications, and for example, displays the switching state in the rotary system by one switch. While the LEDs 33a to 33d provided in the means 22 can be confirmed by being repeatedly turned on sequentially, the abnormality detecting means And to perform the notification in accordance with the switching of the notification by the control means 34 using the internal function of the control unit 12 to the abnormality detection time and operation end by 2. Note that the voice notification unit 31a and the melody notification unit 31b can be a common output device, and in some cases, the buzzer notification unit 31c can also be a common output device. However, if a simple buzzer notification means 31c such as a piezoelectric buzzer is adopted, there is an advantage that the cost is hardly increased and the drive control is simplified.

  In such notification control, when the abnormality is detected or when the operation is finished, the control unit 34 operates the notification unit 31 to perform notification with a sound that is easy to notify a remote user. Since it is performed in accordance with the switching of “voice”, “melody”, “buzzer” or “off”, the user can switch to selecting “voice” and “melody” in order of easy-to-understand information, and become familiar and other devices. Users will be able to simplify the notification status based on the relationship with the usage environment, etc. Four types of notification states can be set. As a result, notifications with sounds that are easy to notify remote users regarding anomaly detection and operation termination are simplified in the order of “voice”, “melody”, “buzzer”, and “off”, which are easy to understand. Accordingly, it is possible to provide a dishwasher that is easy to use based on the selection of the user who wants to omit omission, and is capable of providing an accurate and quick response, and that is less susceptible to dissatisfaction due to excessive notification and other devices.

  However, the present invention is effective even when notification is performed by at least two of “voice”, “melody”, and “buzzer”.

  Further, in the present embodiment, the volume switching means 35 for changing the volume when the control means 34 performs notification by “speech”, “melody”, and “buzzer” is provided as the input means 21. The switching state in the rotary system such as “medium” and “large” can be confirmed while the LEDs 35a to 35c provided as the operation display means 22 can be confirmed by being repeatedly turned on sequentially. As a result, the user sequentially changes the volume to “low”, “medium”, “high”, etc., regardless of the difference in the type of notification mode, by the volume switching means 35, based on his / her wishes and environment. be able to.

  In this case, the volume of “melody” and “buzzer” can be set to “constant volume” only, and the volume switching means 35 can change only the volume of “voice”. In this way, a constant volume is set in the notification mode for “melody” and “buzzer” that does not affect the user and the environment, for example, it is easy to notify a remote user, and an appropriate constant volume that does not affect the user and the environment. On the other hand, in the “voice” notification mode that easily affects the user and the environment, the volume can be changed by the volume switching means 35.

  In the state where the notification is switched to “OFF”, the control means 34 can operate the notification means 31 when an abnormality is detected by the abnormality detection means 32. Thereby, even when the notification is switched to “OFF”, when the abnormality is detected, the notification means 31 is operated to notify, so that it is possible to avoid the notification of the abnormality.

  Next, a specific notification control example shown in FIG. 3 by the control device 12 will be described. When a notification request is confirmed in step S1, a notification switching state is determined in step S2. Next, in step S3, an abnormality is determined, and when it is a notification of an abnormality such as a door closing abnormality, a water supply abnormality, a drainage abnormality, or the like, an abnormality is notified according to the switched mode determined in step S2.

  Specifically, if the abnormality is a door closing abnormality, notification data corresponding to the notification switching related to the door closing abnormality is read in step S4, and the notification means 31 corresponding to the notification switching is stepped in step S8. Driven by the notification data read in S4, it is notified that the door is closed abnormally.

  If the abnormality is a water supply abnormality, the notification data associated with the water supply abnormality is read in step S5, the notification data corresponding to the notification switching is read, and the notification means 31 corresponding to the notification switching is read in step S8. To notify that the water supply is abnormal.

  If the abnormality is a drainage abnormality, the notification data related to the drainage abnormality is read in step S6, the notification data corresponding to the notification switching is read, and the notification means 31 corresponding to the notification switching is read in step S8. To inform that there is an abnormality in drainage.

  If it is not abnormal in step S3, the operation is completed. In step S7, the notification data corresponding to the notification switching is read and the notification means 31 corresponding to the notification switching is stepped in step S8. It is driven by the notification data read in S7 to notify that the operation has been completed.

  On the other hand, if the notification switching in step S2 is off, the notifications in step S4 to step S8 are not performed, and the operation end is confirmed in step S9 and then the buzzer notification means 31c passes through steps S4 to S8. Simple notification compared to.

  In addition, as described above, the operation of switching the sound volume of “speech”, “melody”, and “buzzer” by the sound volume changing means 35 by the sound alert means 31a, the melody alert means 31b, the buzzer alert means 31c, etc. of the alert means 31 is easy and easy. In order to perform accurately, the sound notification means 31, the volume switching means 35 for switching the volume of notification by the notification means 31, and the display elements such as the LEDs 35a to 35c described above for displaying the switched volume are provided. When the volume switching means 35 is operated using the used volume display means 135, the control means 34 switches the volume display means 135 to the volume display means 135, for example, the one corresponding to the currently switched volume is turned off, blinking, or turned on. And more specifically, the volume switching start state by changing from turning off to blinking. Then, when the volume switching means 35 is operated, the display state of the volume display means 135 is changed from blinking to lighting, for example, so that the volume switching by the volume switching means 35 is accepted and the notification volume is switched. Good. As a result, if the operation of the sound volume switching means 135 is operated when the notification means 31 notifies the operation or operation state with the sound of the sound volume displayed by the sound volume display means 135, the control means 34 causes the sound volume display means 135 to It is informed that the user is in a volume switching start state, and the control means 34 changes the display state of the volume display means 135 by the subsequent operation of the volume switching means 135 to indicate the volume switching time point. Is notified to the user, and the volume to be notified is switched by receiving the volume switching.

  As a result, in order to notify the state of operation or operation at the volume displayed by the volume display means 135, the repeated operation of the volume switching means 35 is switched without special notification means by the change in the display of the volume display means 135. While notifying the user of the distinction between the starting state and the switching point, the volume can be switched accurately, and the volume can be switched easily and accurately according to the desired and environment, making it easy to use and due to excessive volume. It is possible to provide a dishwasher that is less likely to cause dissatisfaction.

  Here, the display elements that can be used as the volume display means 135 include organic EL display elements and LCD liquid crystal display elements in addition to the above-described LEDs, all of which are simply turned off, blinking, and turned on as described for the LEDs 35a to 35c. When the volume switching means 35 is operated, the display element is blinked, and the volume to be notified is controlled so that the switching is performed without any special notification means by the blinking of the display element. It is possible to provide a dishwasher that is easy to use by changing the volume easily and accurately according to the desired and environment, and that does not cause dissatisfaction due to excessive volume. .

  In relation to having a plurality of display elements such as the LEDs 35a to 35c described above shown in FIG. 2, in this embodiment, the display elements such as the LEDs 35a to 35c that the control means 34 is turned on according to the sound volume. To change. As described above, the control unit 34 lights the display elements such as the plurality of LEDs 35a to 35c according to the volume, so that the user can be clearly notified of the switching state of the plurality of volumes. In the example shown in FIG. 2, in order to switch the notification volume to three types of “large”, “medium”, and “small” as described above, three LEDs 35a to 35c are associated with each other, and the LED 35a that lights the difference in the volume to be switched. -35c can be displayed to the user, and each LED 35a-35c is clearly indicated to the user with a character display 135a of "large", "medium" and "small" corresponding to the volume to be displayed. ing. At the same time, each of the LEDs 35a to 35c is assumed to have a size corresponding to the volume level to be displayed, specifically, a length, and the LEDs 35a to 35c that are flashed or lit at the switching start time or switching time. Since the user can easily understand whether the corresponding sound volume due to the difference is “high”, “medium”, or “small”, the dishwasher in which various selection operations are performed can be easily used.

  Further, when the volume switching operation is “turn off” of the volume, the control means 34 turns off the display elements such as the LEDs 35 a to 35 c and switches the volume to “turn off”. As described above, when the control unit 34 turns off the display elements such as the LEDs 35a to 35c according to the volume switching operation of “OFF”, the volume “OFF” switching state is caused by the difference from the lighting state at the time of sound notification. Will be switched to “sound cut” while clearly displaying and announcing to the user, so that the user will not feel anxiety or distrust about the absence of sound notification after that. Can do.

  Moreover, the notification means 31 can notify the switched sound volume by the voice notification means 31a in accordance with the switching by the notification switching means 33. Thereby, the difference in the switched sound volume can be clearly notified to the user, and a dishwasher that is easy to use can be provided.

  In this case, when switching to another volume during the voice notification of the switched volume by the voice notification means 31a, the control means 34 interrupts the voice notification of the volume at that time, and the voice for the switched another volume. Voice notification is made by the notification means 31a. As a result, when the volume switched by the voice notification means 31a is notified, if the volume is switched to another volume, the control section 34 interrupts the voice notification of the volume at that time, and the voice for the switched another volume. Since the notification is made, the notification of the volume to be switched can be performed in real time for the volume to be switched each time regardless of the volume notification at the time of the previous switching, and the switching operation and the corresponding voice notification are temporally performed. It can be easy to use without any confusion.

  In this way, the control means 34 takes the voice data D1 corresponding to the switched sound volume as shown in FIG. 4 and the waiting time t for enabling the volume switching to take measures for the new notification accompanied by the interruption of the voice notification. The switching sound volume is informed by reading out the informing data D in which the non-speech data D2 of minutes and the audio data D3 corresponding to the fact that the switching has been made effective. As a result, as illustrated in FIG. 4, during the notification 1 that the volume is switched to, for example, “high” by the previous switching operation of the voice notification unit 31 a, that is, the waiting time t during which switching is valid. When the data D1 or D2 is not passed, and when the volume is switched to another volume, for example, “medium” by the next switching operation, the control means 34 interrupts the current volume 1 and switches the volume. When the notification 2 is performed by voice about another volume “medium” and the next switching operation is not performed until the waiting time t expires, that is, until the notification with the data D1 and D2 is completed, the switching is enabled and the volume switching setting is made valid. The switching setting is notified by the data D3, and the switching of the audio data D1 and the volume is made effective for switching to any volume. And voiceless data D2 Chi hours, the notification data D and the audio data D3 is successively corresponding to that as valid the switching becomes well be used read in response to the switched volume. Accordingly, when there is a switching operation during the next switching operation before the elapse of the predetermined time t when the switching is not effective, that is, during the notification with the data D1 and D2 before the notification reaches the notification with the audio data D3 after the effective waiting time t. The voice notification when switching is enabled at the expiration of the waiting time t, that is, the switching is completed when the waiting time t has expired, while switching the voice notification to the next switching operation is interrupted. The notification measure that shifts to the notification by the data D3 can be achieved by one notification data D that is read once for each volume switching operation. Therefore, it is possible to cope with this by simple data processing using one piece of notification data D, and the cost can be reduced.

  Such control of the control means 34 achieves voice notification that the sound volume is switched at that time when the sound volume switching means 35 is not operated for a predetermined time after the sound volume switching means 35 is operated. In this case, since the next operation is not performed for a predetermined time after the previous switching operation by the volume switching unit 35, the control unit 34 switches the volume by the previous switching operation to be valid and sets the volume to the user. Since the notification is made, the user can clearly notify the user of the volume at the same time as the volume switching setting, easily realized by the above data processing, and confused by the user about the volume switching setting after the last switching operation. It is possible to provide a dishwasher that is easy to use, and that can be switched without giving a light.

  In addition, notification by sound or voice accompanying the switching of the volume is performed at the switched volume. As described above, when the notification volume at the time of the volume switching operation by the volume switching means 35 is performed at the switched volume, it is possible to perform voice notification while making the user feel the switched volume. As a result, the notification volume at the time of the volume switching operation can be performed at the switched volume, and the switched volume can be switched easily and accurately while making the user feel the switched volume.

  Further, when the volume switching is “volume switching”, the notification of the volume switching is performed at any volume that can be switched by the volume switching means 35. As a result, even when the volume switching by the volume switching means 35 is “volume off”, notification to any volume that can be switched by the switching means 35 has been made, so that switching to “volume reduction” has been performed. Can be voice-informed to the user. Therefore, even when the volume switching is “volume reduction”, the user is informed at any volume that can be switched by the switching means 35, and the user is uneasy that the notification by sound or voice is not performed thereafter. Avoiding mistrust.

  Next, the specific volume switching control example shown in FIG. 5 by the control device 12 will be described. When a switching operation is performed in step S31, the current volume is switched including the initial setting in step S32. One of “large”, “medium”, “small”, and “cut” is determined. Based on the judgment result, each time the switching operation is performed, the control is switched to the rotary method sequentially. If the current volume is “high”, it is “medium”, “medium” is “small”, and “small” is “small”. If the current volume is “high”, the current volume is set to “medium” in step S33 and subsequent steps so that the volume is switched to “large” if it is “off”. If the volume is “medium”, the volume “OFF” is switched to the volume “OFF” control in step S41 and below, and if the current volume is “LOW”, the volume “OFF” is switched to step S51 and below. If there is, the process shifts to “large” switching control in step S61 and thereafter. For example, in the case of the volume “medium” switching control in step S33 and subsequent steps, the LED “middle” blinks to indicate that the transition to the volume “medium” has been switched, and in step 34 the volume “middle” is switched. Voice notification by the notification data D corresponding to “medium” is started. Next, while determining whether or not the next switching operation has been performed, the processing is repeated until the voice data D1 of the notification data D + the switching effective waiting time t ends. When D1 + t ends without the next switching operation, the switching to the volume “medium” confirmed in step S32 is validated, the process proceeds to step S37 to switch to the volume “medium”, and the LED “medium” is lit in step S38. To indicate that the setting to switch to “medium” is complete. Next, the process proceeds to step S57, and the process returns after waiting for the end of the notification of the data D3 for notifying that the volume setting of the notification data D has been set. When the next switching operation is performed in step S35, the notification control by the notification data D at the volume “medium” is interrupted, and the control shifts to the switching control for the volume “small” which is the rear stage of the volume “medium”. That is, the process proceeds to control after step S41. Even when the current volume is “medium” in step S32 and the control shifts to the “small” volume control in step S41 and lower, the current volume is “off” in step S32 and the volume “off” in step S51 and lower is switched. Even in the case of shifting to control, the control is not particularly changed in the case of shifting to the switching control in which the volume is “OFF” in step S32 and the volume is set to “large” in step 61 or less. In the switching control to “OFF”, as shown in the figure, the current switching LED “Small” determined in Step S32 is blinked to start the control, and when the switching becomes valid, the LED “Small” is turned off. It is easy to understand and suitable.

  Furthermore, in this embodiment, when the opening / closing of the door 1a is detected by the door opening / closing detection means 8, and the opening / closing state of the door 1a such as an abnormal closing of the door 1a is notified by voice, the start switch 16 for starting operation, When there is a start input from the start switch 16 using the opening / closing detection means 8 and the voice notification means 31a, the control means 34 makes a sound by the voice notification means 31a according to the detection state of the door opening / closing detection means 8. Change the notification content to "Door is open", "Door is not fully closed", "Door is open", etc. As a result, when the preliminary work for dishwashing in the dishwasher is completed, the user operates the start switch 16 to start operation. At this time, the control means 34 is configured to detect the door opening / closing detection means 8 by the sound notification means 31a. Since the notification content by voice is changed as described above in accordance with the detected state, the difference in the detected state of the door opening and closing at the start of operation can be clearly communicated to the user. As described above, when the notification content by voice is changed according to the door opening / closing detection state at the start of driving and the difference in the door opening / closing detection state is clearly communicated to the user, the user opens / closes the door 1a at the start of driving. Knowing the state accurately, if there is a closing error, you can respond immediately, and if there is no closing error, you can move on to the next operation with peace of mind.

  Here, when the user responds to the closing abnormality and the closing abnormality is resolved, a notification such as “Start driving on the course” is given with a voice notification to that effect or by a restart operation without voice notification. If there is no closing abnormality, it is convenient to use if the operation is started with voice notification.

  In particular, the door opening / closing detection means 8 has a plurality of door opening / closing detection means 8a, 8b,... For detecting the open / closed state of the door 1a as shown in FIG. When the detection states of the plurality of door open / close detection means 8a, 8b,... Are all open by 34, a voice notification is given in consideration of the fact that the door 1a is completely open and is not in a situation of starting operation. Do not. Thereby, the open / closed state of the door 1a is detected at a plurality of locations of the door 1a by the plurality of door open / close detecting means 8a, 8b,..., And the door 1a is bent or elastically repelled by the locking mechanism to the closed position. The fact that the difference in the closed state can be partially caused by an influence corresponds to the difference in the detection state of the plurality of door opening / closing detection means 8a, 8b,... And the plurality of door opening / closing detection means 8a, 8b at the start of operation. Of the differences in the door open / closed detection states, it is possible to clearly tell the user whether or not all the detection states are open as a difference between performing voice notification and not performing it. In this way, by correlating the difference in the detection state of the door opening / closing at the plurality of locations with the difference in the partial opening / closing status at the plurality of locations of the door 1a, whether or not all the detection statuses are opened at the start of the operation by voice. If the user is clearly informed of the presence / absence of this notification, the user can move on to the next operation with peace of mind that there is no abnormality in closing if there is no audio notification regarding opening / closing of the door at the start. Further, the dark voice notification does not affect the troublesomeness to the user or listening to other device notifications.

  Moreover, when all the detection states of the plurality of door opening / closing detection means 8a, 8b,... Change to closed, the control means 34 notifies by voice so that all of the plurality of door opening / closing detection states change to closed. Corresponding to this, the control means 34 notifies by voice, so that the user can be clearly informed that the door 1a has changed to the completely closed state. In this case, the sound may be “The door is closed, ... start driving on the course", "... start driving on the course", etc. Thus, in response to the fact that all of the detection states of the door opening and closing have all changed to closed, a voice notification is made, and when clearly telling the user that the door 1a has changed to the fully closed state, The user can move on to the next operation without worrying about the abnormal closing of the door 1a, which is often overlooked, and without worrying about the abnormal closing.

  Further, in response to whether the detection state of the plurality of door opening / closing detection means 8a, 8b,... Is combined with opening and closing, the control means 34 changes the notification content by voice to “the door is completely closed. `` No '', `` No voice '', `` Door closed, ・ Start driving on course '' or `` Start driving on course '', etc. The door opening / closing detection means 8a, 8b,... Is detected at a plurality of positions of the door 1a, and the door 1a is partially closed. Corresponding as a difference in state, the control means 34 changes the notification content by voice depending on whether or not opening and closing are combined in a plurality of door open / closed detection states, and the door 1a is partially opened. Clearly indicate to the user whether there is a closing error I can tell. In this way, whether the opening and closing are combined in the plurality of detection states by corresponding the difference in the detection states of the door opening and closing in the plurality of locations to the difference in the partial opening / closing states in the plurality of locations of the door 1a. If the content of the notification by voice is changed, the user is clearly informed of the presence or absence of a closing abnormality such that the door 1a is partially opened, and the user partially closes the door 1a which is often overlooked. You can immediately respond by knowing whether or not there is a closing error, or move on to the next work without anxiety.

  Next, a specific control example of the door opening / closing state notification shown in FIG. 6 by the control device 12 will be described. When the start switch 16 is confirmed to be turned on in step S21, the door opening / closing detection means 8a is turned on in step S22. If it is on, it is determined in step S23 that the door opening / closing detection means 8b is on. Under the condition that both the door opening / closing detection means 8a and 8b are on and the door 1a is completely closed, the process proceeds to step S24, and the voice notification A is performed with a voice such as “.. starts driving on the course” and returns. .

  If the door opening / closing detection means 8a is off in step S22, the process proceeds to step S25 to determine whether the door opening / closing detection means 8b is on. If both the door open / close detecting means 8a and 8b are off, the door 1a is completely or clearly open to the user, so that the voice notification is omitted and the process returns.

  If the door opening / closing detection means 8b is off in step S25, it is determined in step S26 whether the door opening / closing detection means 8a is on. If the door opening / closing detection means 8b is off in steps S26 and S23, both door opening / closing detection means are detected. Since either 8a or 8b is on, and one of them is off and on and off are combined, and the door 1a is partially closed, it is a closed abnormality. It returns with a sound such as “It is not completely closed”. Note that when the door opening / closing detection means 8a is on in step S26, the door 1a is completely open, so the voice notification is omitted as described above, and the process returns.

  In the present invention, the volume of sound notification in the dishwasher can be switched as necessary or desired.
