Next, the outline | summary of a series of operation | movement of the dishwasher 40 is demonstrated.

A user (not shown) of the dishwasher 40 arranges the dishes in a dish basket (not shown) and stores them in the washing tank 2. Then, detergent is thrown in and the door 1a is closed. Thereafter, the power input switch 14 and the start input unit 16 are operated to start the operation of the dishwasher 40. When operation of the dishwasher 40 starts, tap water is supplied from the water supply valve 3 to the bottom part of the washing tank 2 until the water level detection part 10 detects a predetermined water level. Then, while the washing pump 4 and the heater 5 are energized, the washing water is heated, and the washing pump 4 blows out from the washing nozzle toward the dishes.

At this time, the temperature detection unit 9 detects the temperature of the washing water, and the control device 12 always monitors the temperature of the washing water. When the temperature of the washing water reaches a predetermined temperature or when a predetermined time elapses from the start of washing, the control device 12 ends the washing stroke. At the same time, the drain pump 6 is energized, and once washing water is drained from the bottom of the washing tank 2.

As described above, a series of operations of washing, rinsing and drying of the dishwasher 40 are performed.

In the conventional dishwasher, when an abnormality is detected by the abnormality detection part or when operation | movement is complete | finished, it reports to a user by a simple buzzer sound or LED. In the dishwasher 40 of the present invention, as shown in FIG. 1, the report unit 3l includes a plurality of selectable sound units 31a, melody report unit 31b, and buzzer report unit 31c. I have a way to report. The voice report unit 31a reports using "voice", the melody report unit 31b reports using "melody", and the buzzer report unit 31c reports using "buzzer". In addition, the input unit 21 has a report switching unit 33. The report switching unit 33 selects and switches the types of reports such as "voice", "melody", "buzzer", and the like. Alternatively, the report switching unit 33 may stop the report by "off". For example, the report switching unit 33 is constituted by one switch 33e. As the switch 33e is repeatedly pressed, the reporting method can be changed in a rotary manner. The changed state of the selected report is displayed by the LEDs 33a, 33b, 33c, 33d provided in the operation display unit 22. That is, as the switch 33e is repeatedly pressed, the LEDs 33a to 33d light up in sequence. According to this, the status of the selected report is confirmed, and the reporting method is selected. Moreover, when abnormality detection by the abnormality detection part 32 or operation | movement is complete | finished, the control part 34 using the internal function of the control apparatus 12 reports according to the selected report method. In addition, the LEDs 33a, 33b, 33c, 33d constitute a display element.

The voice report unit 31a and the melody report unit 31b can use a common output device (not shown) such as a speaker. In some cases, the buzzer reporting unit 31c may also use a common output device. However, the buzzer report part 31c has the advantage that there is little cost increase and simple drive control is realized by employing an output device having a simple configuration such as a piezoelectric buzzer.

In the report control, at the time of abnormality detection or at the end of the operation, the control unit 34 controls and drives the report unit 31, and the report is performed by a sound that is easy to be notified even to a user who is away. That is, the report is made in accordance with the selection result of "voice", "melody", "buzzer", or "off" switched by the report switching unit 33. For example, the user can report the contents of the report in an easy-to-recognize manner at the time of abnormal detection or at the end of the operation by selecting and changing the contents of the report in the order of "voice" or "melody" which are easy to understand. have. In addition, the reporting method may be simplified due to a familiarity or a balance with a use environment such as another device. In some cases, the simplest "buzzer" may be selected. In addition, "off" not reporting to sound may be selected. As described above, the user can freely select and set four types of reporting methods. As a result, in the case of abnormal detection and end of operation, the report in the form of sound which is easy to be notified even to the user who is away from the dishwasher 40 is easy to recognize the contents of the report "voice" "melody" "buzzer" The switch is simplified in the order of "off".

In addition, when the user wishes to omit the report, the report is executed by using a report method based on the user's selection. As a result, a report is made which allows for easy-to-use, accurate and agile response. In addition, there is provided a dishwasher 40 which is free from complaints by excessive reports, is not confused with reports by other devices, and executes appropriate reports.

Note that the present invention is effective even when the report is made using at least two reporting methods of "voice", "melody" and "buzzer". For example, it is also possible to report by a combination of "voice" and "melody" and to report by a combination of "voice" and "buzzer". As a result, the degree of recognition of the user is further increased.

In addition, the input unit 21 has a volume switching unit 35. The volume switching unit 35 is used to switch the volume of the report. That is, the volume switching part 35 selects the volume of the report by "voice", "melody", and "buzzer". For example, the volume switching part 35 is comprised by one switch 35d. As the switch 35d is repeatedly pressed, the volume is switched in a rotary manner such as "small", "medium", "large", "off". The state of the switched and selected volume is displayed by the LEDs 35a, 35b, 35c provided in the operation display unit 22. That is, as the switch 35d is repeatedly pressed, the LEDs 35a to 35c light up sequentially. In this way, the volume of the report is switched and operated while the state of the volume of the report is confirmed. Therefore, the user can switch and select the volume by the volume switching unit 35 based on the user's desire or the relationship of the environment in which the dishwasher 40 is installed. In addition, for example, "small", "medium", "large", "off", and the like are sequentially switched for the volume. The volume switching can be freely selected irrespective of the type of the report mode.

In addition, the volume of "melody" and "buzzer" is fixed only to "constant volume", and the volume switching unit 35 may switch only the volume of "audio". As a result, reports of "melody" and "buzzer", which are difficult to influence the user's selection or the situation of the environment, are performed at a constant volume, and are easily notified to a user who is in a remote place. In addition, the reporting mode of "melody" and "buzzer" is set to an appropriate constant volume which is not affected by the user's selection or the state of the environment, and in addition, in the reporting mode by "voice", the volume switching unit ( 35), the volume can be changed. That is, in the report mode by "voice", the report information is recognized by the content of the voice. For this reason, the report by "voice" is easily influenced by the user's selection or the state of the environment. Therefore, as the volume of the report by "voice" is freely varied, the volume easily perceived by the user is appropriately selected.

In addition, even when the report is set to "off", when the abnormality is detected by the abnormality detecting unit 32, the control unit 34 can operate the reporting unit 31. As a result, even when the report is switched to " off ", the report unit 31 is operated to perform the report. In this way, reporting at the time of abnormality is performed correctly.

Next, a control example of the report processing performed by the control device 12 will be described with reference to FIG. 4.

First, as shown in FIG. 4, in step S1, a report request is confirmed. If the report request is confirmed, in step S2, the switching state of the report is determined. Next, in step S3, the abnormality detection unit 32 performs the abnormality determination. As a result of the abnormality detection unit 32 determining the abnormality, in the case of abnormality such as a door closing abnormality, a water supply abnormality, a drainage abnormality, or the like, the abnormality report is performed by the report mode according to the report switching state determined in step S2.

For example, when the determined abnormality is the door closing abnormality, in step S4, report data relating to the door closing and corresponding to the report switching state is read out and stored in the storage unit 41. Moreover, in step S8, the report part 31 corresponding to the report switching state is driven based on the report data read in step S4, and reports that it is more than door closing.

If the determined abnormality is a water supply abnormality, in step S5, report data relating to the water supply abnormality and corresponding to the report switching state is read out and stored in the storage unit 41. In addition, in step S8, the report unit 31 corresponding to the report switching state is driven based on the report data read in step S5, and reports that the water supply is abnormal.

If the determined abnormality is a drainage abnormality, in step S6, report data relating to the water supply abnormality and corresponding to the report switching state is read out and stored in the storage unit 41. In addition, in step S8, the report part 31 corresponding to the report switching state is driven based on the report data read in step S6, and reports that it is more than a multiple.

In addition, in step S3, when it determines with the abnormality detection part 32 not being abnormal, the completion | finish of operation is reported. That is, in step S7, report data relating to the end of the operation and corresponding to the report switching state is read out and stored in the storage unit 41. In addition, in step S8, the report unit 31 corresponding to the report switching state is driven based on the report data read in step S7 to report that the operation is completed.

On the other hand, if it is determined in step S2 that the switching state of the report is "off", the report displayed in steps S3 to S8 is not performed. In addition, in step S9, the operation end is confirmed. When the operation end is confirmed, the buzzer report unit 31c simply reports. In addition, the simple report made by the buzzer report part 31c is a simple report compared with the report made through step S3-step S8.

Moreover, as mentioned above, in the dishwasher 40 of this invention, the volume switching part 35 and the volume display part 45 are used, and the volume of the report of the report part 31 which used the sound is switched. As a result, the voice report unit 31a which executes the report by "voice", the melody report unit 31b which executes the report by "Melody" and the buzzer report unit 31c which performs the report by "Buzzer" The volume of the report, such as), is easily and accurately switched by the volume switching unit 35. Moreover, the volume display part 45 is comprised by display elements, such as LED35a-35c which show the switched volume.

For example, when the switch 35d is pressed and the volume switching unit 35 is operated, the volume display unit 45 indicates that the volume switching start state is in effect. For example, when the volume switching unit 35 is operated, the volume display unit 45 is switched at the present time by the control from the control unit 34, so that the display element corresponding to the selected volume is turned off, flashes, It changes to the state of lighting. That is, any one of the LEDs 35a to 35c changes from off to flashing. This notifies that the volume switching start state has been reached. Thereafter, when the volume switching unit 35 is operated, the display state of any one of the LEDs 35a to 35c of the volume display unit 45 changes from flashing to lighting, for example. As a result, the volume switching unit 35 receives the volume switching, and determines the report volume of the report unit 31 based on the selected volume.

As mentioned above, the volume display part 45 displays the state of the operation or switching operation | movement which switch the volume of report. The user can easily recognize whether the volume switching operation is in the starting state, the volume is selected, or whether the volume selection is accepted. That is, the user can accurately perform the switching operation of the volume while visually recognizing the state of the operation displayed on the volume display unit 45. In addition, the volume display part 45 is controlled by the control part 34 at this time.

Thus, the volume switching part 35 is repeatedly operated in the state which the volume display part 45 displayed the state of the operation of volume switching, or the state of operation. When the volume switching unit 35 is operated, the display of the volume display unit 45 changes in response to the operation of the volume switching unit 35. In this way, even if there is no special notification unit, the user can be notified of the distinction between the switching start state and the switching state accurately, and the user can switch the volume accurately. In addition, the volume of the report can be freely switched simply and accurately freely in accordance with the user's desire or the environment in which the dishwasher 40 is installed. Thus, there is provided a dishwasher 40 which is easy for the user to use and which is difficult to complain to the user of the excessive volume.

In addition to the LEDs described above, an organic EL display element, an LC D liquid crystal display element, or the like can be used for the display element used as the volume display unit 45. In either case, the display having simple distinction such as off, flashing, lighting, etc., which have described the LEDs 35a to 35c as an example, is possible. Therefore, when the volume switching unit 35 is operated to start volume switching, the display element flashes, and switching control of the volume to be reported is executed. As a result, the volume switching operation is notified to the user by the blinking of the display element even without other special notification unit.

The dishwasher 40 of the present invention has a plurality of LEDs 35a to 35c as shown in FIG. 3. Moreover, the control part 34 makes a change by turning on LED35a-35c etc. according to switching of a volume, selection. In this way, as the control unit 34 lights the plurality of LEDs 35a to 35c in accordance with the volume, the switching state of the volume can be clearly reported to the user. For example, as shown in Fig. 3, the report volume is switched to three types of "large", "medium" and "small". On the basis of the switching of the reported volume, the three LEDs 35a, 35b, and 35c correspond to the volume "small", "medium" and "large" respectively selected. The difference in the volume to be switched is recognized by the user as the difference between the LEDs 35a to 35c which are lit at that time. Moreover, around each LED 35a-35c, the character display 45a of "large", "medium", and "small" corresponding to the volume to be displayed is provided. Accordingly, the user can clearly recognize the volume being switched. Moreover, each LED 35a-35c has the magnitude | size corresponding to the magnitude | size of the volume to display, so-called area. Specifically, for example, the lengths of the LEDs 35a to 35c each have a length corresponding to the volume displayed. As a result, at the switching start time or switching time point, the correspondence between the LEDs 35a to 35c which are blinking and lighted and the volume is accurately performed. Therefore, the user can intuitively recognize whether the volume is one of "large", "medium" and "small". For this reason, the volume switching convenience is further aimed, and the dishwasher 40 which is easy to use is provided.

In addition, when the volume to be switched and selected is " off ", the control section 34 turns off the LEDs 35a to 35c. As a result, the control unit 34 clearly notifies that the volume of neglect is selected as " off ". Thus, the control part 34 turns off LED35a-35c according to the volume switching operation of "off". As a result, the case where the report by sound is selected and the case where the report by the sound is set to "off" and the report without sound is selected is easily selected by the difference in the lighting state of the LEDs 35a to 35c. You are notified. Since the user can easily recognize that the "sound off" has been selected, the user is restrained from feeling anxious or distrusted since no report using the sound is made thereafter.

In addition, the display of the state of the switching operation | movement of the volume switching part 35 is not limited only to the display by the volume display part 45. FIG. For example, when the report mode by the audio | voice report part 31a is selected by the report switching part 33, the volume switched volume in the volume switching part 35 is an audio | voice report part 31a. It may be reported by voice by). As a result, the user is notified of the difference in the switched volume more clearly. As a result, a dishwasher 40 that is easier to use is provided.

In addition, when the volume switched by the volume switching unit 35 is switched to another volume during the voice report by the voice report unit 31a, the control unit 34 reports information on the volume at that time. The voice report may be stopped, and the voice report may be reported on information about a new separate volume switched by the volume switching unit 35. As a result, the volume of the volume switched by the volume switching unit 35 is reported in real time. For this reason, the volume switching operation and the voice report corresponding to the operation are not shifted in time, and the user can execute the volume switching operation without any confusion.

As described above, when the voice report is switched, the control section 34 executes a new report action following the interruption of the voice report. Hereinafter, a detailed description will be given with reference to FIG. 5.

As shown in Fig. 5, the report data Dx for the report X at the time of volume switching is continuous first audio data D1, non-voice data D2, and second audio data D3, respectively. It includes. The first audio data D1 is audio data corresponding to the converted volume. The unvoiced data D2 is unvoiced data corresponding to the wait time t until the volume change becomes effective. The second audio data D3 is audio data that is reported in response to the effective voice switching.

When the volume is switched by the volume switching unit 35, the report data Dx is read and stored in the storage unit 41. According to the report data Dx stored in the storage unit 41, the audio report of the information regarding the switched volume is performed. FIG. 5 shows an example of executing report X as the volume is switched to "large", for example. In addition, an example is shown in which the next volume switching operation is executed while the report X is being reported by voice, that is, before the waiting time t for which the switching is valid has elapsed. That is, the next volume switching operation is performed in the middle of the report by the first audio data D1 or the non-voice data D2. In addition, by the next volume switching operation, it is switched to another volume "medium". Thereby, the control part 34 interrupts the report (X) of the volume at that time, and performs the report (Y) regarding the other volume "medium" switched next. Here, the report data Dy for the report Y at the time of volume switching includes continuous first audio data D1, non-voice data D2 and second audio data D3, respectively. The first audio data D1 is audio data corresponding to the converted volume. The unvoiced data D2 is unvoiced data when it corresponds to the waiting time t until the volume change becomes effective. The second audio data D3 is audio data that is reported in response to the effective voice switching. When the volume is switched, the report data Dy is read out and stored in the storage unit 41. The report volume Dy stored in the storage unit 41 reports the converted volume. 5 shows an example of executing report Y as the volume is switched to "medium".

In the audio report after the volume switching operation, the next switching operation is performed until the waiting time t expires, that is, until the completion of the reporting of the first audio data D1 and the unvoiced data D2. If not present, volume switching becomes effective. In addition, the switching setting of the volume is performed, and with this, the switching setting by the second audio data D3 is reported. Regarding switching to either volume, it corresponds to the first audio data D1, the non-voice data D2 for the waiting time t for validating the switching of the volume, and the volume switching being valid. The report data D in which the second audio data D3 is continuous is used. In addition, the report data D is read out corresponding to the switched volume, stored in the storage unit 41, and used for reporting. Therefore, only when the next switching operation is performed before the predetermined time t before the volume switching becomes effective, control of interruption of the voice report and switching to the voice report corresponding to the next voice switching operation are performed.

In addition, before the predetermined time (t) elapses before the volume switching becomes effective, the first audio data (D1) before the report reaches the report by the second audio data (D3) after the effective waiting time (t) is not. It means when there is a switching operation during the reporting of the audio data D2. Therefore, the report is shifted to the voice report when the volume switch is valid when the waiting time t expires, that is, the report by the second voice data D3 that is reported after the waiting time t expires and the switching is completed. An action may be read once once for each volume switching operation. Therefore, these audio reports are executed by the configuration of a simple data processing used for reading one report data D. FIG. For this reason, the dishwasher 40 by which accurate audio | reporting is performed at low cost can be obtained.

In addition, the control by the control part 34 performs a volume switching setting based on the volume already switched at the time when the 2nd operation is not performed for a predetermined time, after the volume switching part 35 is operated. This volume switching setting is also reported by voice. As the next operation is not performed between the previous volume switching operation by the volume switching unit 35 for a predetermined time, the control unit 34 validates the volume by the previous switching operation. For this reason, at the same time as the volume switching setting, the sound volume to the user is clearly notified. This voice notification is realized by simple data processing as described above. From the point where the volume switching operation is finally performed, the volume switching setting is set to a time delay. However, since information on the set volume is appropriately reported by voice, the volume switching is executed without confusing the user. As a result, the dishwasher 40 which is easy to use is provided.

In addition, you may report by the sound or audio | voice by volume change operation to the switched volume. In this way, since the report volume at the time of the volume switching operation performed by the volume switching unit 35 is performed by the switched volume, the user can operate the volume switching while the switched volume is realized by the user. As a result, the report volume at the time of the volume switching operation is performed at the volume to which the volume has been switched, and the volume switching operation is easily and accurately performed while the switched volume is realized by the user. According to this, the dishwasher 40 which is easy to use is provided.

In addition, when the volume switching is set to "volume off", the audio report of the volume switching may be performed at any one volume that can be switched by the volume switching unit 35. Thereby, even when the volume switching by the volume switching part 35 is "volume off", a voice report is reported to the user that volume switching was performed by "volume off". Therefore, even when the volume switching is "volume off", the voice report is made to the user, and the user recognizes that it is set to "volume off" clearly. For this reason, the dishwasher 40 which is easy to use is provided without a voice report being performed, and a user not being insecure or distrustful.

Next, an example of the volume switching control performed by the control part 34 of the control apparatus 12 is demonstrated using FIG.

First, in step S31, it is determined whether or not there is a volume switching operation. If it is determined that there is a volume switching operation, in step S32, the volume that is switched and set at this point in time is confirmed. The volume to be checked includes the volume set initially, and is, for example, "large", "medium", "small", "off". The switching operation of the volume is switched by the rotary method in order every time of those switching operations from the confirmation result in step S32. In addition, the order of sending in order of volume switching is not limited to "large", "medium", "small", "off". For example, "small", "medium", "large" and "off" may be used.

In the procedure shown in FIG. 6, if the current volume is "large" on the control of the volume switching operation, the next volume is switched to "medium". Similarly, if the current volume is "medium", the next volume is switched to "small"; if the current volume is "small", the next volume is switched to "off"; if the current volume is "off", The volume is switched to "large". That is, it is switched to the rear volume once. In this way, for example, when the current volume is "large", the control shifts to the control for switching to the volume "medium" in step S33 or below. Similarly, if the current volume is "medium", the control shifts to the volume "small" in step S41 or below. If the current volume is " small ", the control proceeds to the switching control to the volume " off " If the current volume is " off, " the control shifts to the volume " large "

As an example of the volume switching operation, the volume "large" is confirmed in step S32, and the switching control to the volume "medium" of step S33 or less is demonstrated in detail below.

First, in step S33, the LED 35b indicating the volume "medium" flashes, indicating that the transition to the volume "medium" has been made. Next, in step S34, the voice report by the report data D corresponding to the volume "medium" is started. Next, in step S35, it is determined whether or not the corner where the next volume switching operation has been performed is obtained. Steps S34 and S35 are performed until the first audio data D1 and the switching valid waiting time t end. It is repeated (step S36). If the time D1 + t ends without the next volume switching operation, the volume "middle" switched from the volume "large" identified in step S32 becomes valid, and the flow proceeds to step S37. Next, in step S37, the volume is switched to the volume " medium ", and the voice report by the second voice data D3 is performed. In step S38, the "medium" LED 35b is turned on, indicating that the switching setting to the volume "medium" is completed. Subsequently, the process proceeds to step S57 to determine whether or not the audio report by the second audio data D3 has ended. When the audio report by the second audio data D3 ends, the process returns to the end of the report volume switching process.

In step S35, when there is a next volume switching operation, the report control by the report data D by the volume "middle" is interrupted midway, and the switching control about the volume "small" which is the rear end of the volume "middle" is interrupted. To fulfill. That is, the process shifts to the control of step S41 or less, and the process of switching the report volume is continued.

In addition, in step S32, when it is confirmed that the current volume is "medium", and shifts to the control for switching to the volume "small" of step S41 or less, the process is performed similarly to the operation after step S33 mentioned above. In addition, in step S32, when it is confirmed that the present volume is "small", and the control shifts to the switching to the volume "off" of step S51 or less, the process is performed similarly to the operation after step S33 mentioned above. In addition, in step S32, when it is confirmed that the current volume is "off", and shifts to the control for switching to the volume "band" of step S51 or less, the processing is performed in the same manner as the operation after step S33 described above. In addition, in the control of switching to the volume "off" of the step S51 or less, as shown in Fig. 6, the LED 35a corresponding to the "small" of the current volume switching confirmed in step S32 flashes to start the control. do. When the volume switching to "small" becomes effective, the LED 35a corresponding to "small" goes out. Accordingly, it is preferable for the user to easily recognize that the volume is set to "off".

In addition, the open / close state of the door 1a is detected by the door open / close detection unit 8. Moreover, the abnormality regarding the opening / closing state of the door 1a is reported. At this time, when there is a start input from the start input unit 16, the control unit 34 controls the voice report unit 31a to set the contents of the report by voice. In this case, the setting of the report content reported by the voice is set to, for example, "the door is open" or "the door is not completely closed" according to the detection state of the door open / close detection unit 8. In this way, the setting of the report content is set in conjunction with the start input unit 16, the door open / close detection unit 8, and the audio report unit 31a. Moreover, the abnormality regarding the opening / closing state of the door 1a is the abnormality of the closing of the door 1a, etc., for example.

When the preliminary work of dishwashing in the dishwasher 40 is finished, the user operates the start input unit 16 to start the operation of the dishwasher 40. In the preliminary work of dish washing, tableware is arrange | positioned in the dish basket and is accommodated in the washing tank 2, for example. Or detergent is thrown in and the door 1a is closed. When the start input unit 16 is operated and operation is started, the control unit 34 controls the voice report unit 31a in accordance with the detection state of the door open / close detection unit 8, and sets the report content by voice. . As a result, the difference in the detection state of the door opening and closing at the start of operation is clearly communicated to the user. As a result, the user knows whether the opening / closing state of the door 1a is correctly performed at the start of the operation of the dishwasher 40, and can respond immediately if there is an abnormality of closing. In addition, when there is no closing abnormality, the user can safely perform the following operation.

In addition, when the user responds appropriately to the closing abnormality reported by the voice, and the closing abnormality is solved, a voice report indicating that the closing abnormality has been eliminated may be reported. In addition, a voice report indicating that the closing abnormality has been eliminated is not reported, and a report such as "Start driving at the course" may be reported as the restart operation is performed. That is, the report is made in accordance with the restart operation, and the operation of the dishwasher 40 is started. In addition, when there is no closing abnormality, a report regarding abnormal closing of the door is not performed, and driving may be started with a voice report such as "Start driving at the course". Thus, as the operation of the dishwasher 40 is started, the dishwasher 40 which is conveniently used is provided.

Moreover, the door opening / closing detection part 8 may have several door opening and closing detection parts 8a and 8b which detect the opening / closing state of the door 1a in the several left and right positions of the door 1a. If the door open / close detection unit 8 has a plurality of door open / close detection units 8a and 8b, and the abnormality detection unit 32 determines that the state of detection of the plurality of door open / close detection units 8a and 8b is all open, the door It is determined that 1a is in a fully open state. In addition, when it is determined that the door 1a is in the fully open state, even if the start input unit 16 is operated, reporting by voice is not performed. That is, since the door 1a is in a fully open state, it is considered that the operation of the dishwasher 40 is not started, and no report by voice is performed. Accordingly, the user accurately recognizes that an abnormality of closing the door is occurring.

Further, the door open / close detection unit 8 has a plurality of door open / close detection units 8a and 8b, and the abnormality detection unit 32 determines that the state of detection of the plurality of door open / close detection units 8a and 8b is a mixture of open and closed. If it is, it is determined that the door 1a is in a partially closed state. In addition, the door 1a is in the partially closed state, for example, the locking mechanism of the door 1a or the locking mechanism in the closed position may be affected by elastic repulsion or the like, so that the door 1a may be partially closed. This is assumed. In addition, when it is determined that the door 1a is in the partially closed state, an audio report is issued to the effect that the door 1a is in the partially closed state. Accordingly, the open / closed state of the door 1a is accurately transmitted to the user due to the difference between the case where the report by voice and the report by the voice are not.

As described above, the plurality of door opening / closing detection parts 8a and 8b are provided, and the difference in the partial opening / closing state of the door 1a is reflected in the difference in the detection result of the plurality of door opening / closing detection parts 8a and 8b. . Further, based on the detection results of the plurality of door opening / closing detection units 8a and 8b, it is clearly communicated to the user as the presence or absence of a report by audio at the start of driving. That is, the user can move to the next operation in peace as there is no closing abnormality when operation is started in the state in which there is no audio report regarding door opening and closing at the start of operation of the dishwasher 40. In addition, it is possible to avoid confusion with reports of other devices, etc., which are cumbersome to the user, by the blind voice report, so that the report information is correctly recognized.

In addition, when the detection states of the plurality of door open / close detection units 8a and 8b are all changed to closed, the control unit 34 reports by voice. In this way, since a report by voice is performed, the user can clearly recognize that the door 1a has been changed to a completely closed state. The sound in this case may be set to, for example, "the door is closed, driving starts at the course" or "start driving at the course". In this way, a report by voice is made in response to the detection state of the plurality of door opening / closing detection parts 8a and 8b being changed to closed, and the user is clearly informed that the door 1a is changed to the fully closed state. For this reason, the user transfers to the next operation in peace, as there is no closing abnormality, without giving strange attention to the partial closing abnormality of the door 1a which tends to be overlooked.

In addition, in the detection state of the some door opening / closing detection part 8a, 8b, the control part 34 sets the report content by audio | voice with the opening and closing being mixed or not. The report content by sound is, for example, when the opening and the closing are mixed in the detection state of the plurality of door opening / closing detection parts 8a and 8b. Is performed. For example, when the detection states of the plurality of door opening and closing detection units 8a and 8b are all open, the report content by sound is set to "silent voice". For example, when the detection state of the plurality of door opening / closing detection units 8a and 8b is changed to closed, the report content by the voice is, "The door is closed and starts driving in the course" or " Start driving on the course ”.

Thus, the opening / closing state of the door 1a is detected by the plurality of door opening / closing detection parts 8a and 8b, and based on the difference in the detection state of each door opening / closing detection part 8a and 8b, A partial closed state is determined. Moreover, the control part 34 sets the report content by audio | voice by the opening and closing | mixing or the opening and closing | mixing not mixed in the several detection state of opening and closing of the door 1a. Thus, for example, the presence or absence of an abnormality in closing, such as the door 1a being partially opened, is clearly communicated to the user.

As mentioned above, opening and closing are mixed in the detection state of the several door opening and closing detection parts 8a and 8b based on the difference of the partial opening and closing state in the detection state of the several door opening and closing detection parts 8a and 8b. Based on the information being made or not mixed, the report content by voice is set. As a result, the presence or absence of the closing abnormality such as the door 1a being partially opened is clearly communicated to the user. Therefore, the user can easily recognize the presence or absence of the closing abnormality without paying attention to the partial closing abnormality of the door 15a which tends to be overlooked. As a result, the user can respond to the closing abnormality immediately. Along with this, the user can move to the next task with confidence.

Moreover, in the dishwasher 40 of this invention, the door open / close detection part 8 demonstrated the structure which has two door open / close detection parts 8a and 8b. However, the door open / close detection unit 8 is not necessarily limited to two. That is, three or more may be provided according to the structure of the dishwasher 40 or the structure of the door 1a, the opening-closing part of the door 1a, and the structure of the lock part. In addition, the door 1a is not limited to one, and the two-piece door 1a may be used. Moreover, when the two-door door 1a is used, it is set as the structure by which the several door opening / closing detection part 8 is provided in each door 1a, and the abnormality of closing of the door 1a is also detected with high precision. do.

Next, the control example of the door opening / closing state report performed by the control apparatus 12 is demonstrated using FIG.

First, as shown in FIG. 7, it is confirmed in step S21 whether the start input part 16 is on. If the start input unit 16 is on, in step S22, the on / off of the door open / close detection unit 8a is determined. When the door open / close detection unit 8a is on, in step S23, the on / off of the door open / close detection unit 8b is determined. In this way, when it is determined that both of the door opening and closing detection units 8a and 8b are on, the door 1a is determined to be completely closed. Accordingly, the process proceeds to step S24 based on the condition that the door 1a is completely closed. For example, ". The voice report (A) is made by the voice such as "Start driving on the course", and the flow of the door opening / closing status report ends.

If it is determined in step S22 that the door open / close detection unit 8a is turned off, the process proceeds to step S25 and it is determined whether the door open / close detection unit 8b is on. In step S25, when it is determined that the door open / close detection unit 8b is off, since both of the door open / close detection units 8a and 8b are off, the door 1a is opened completely or in a clear state for the user. It is determined. For this reason, the voice report is omitted, and the flow of the door open / close state report ends.

Furthermore, when it is determined in step S25 that the door open / close detection unit 8b is on, it is determined in step S26 whether the door open / close detection unit 8a is on again. In addition, in step S26 and step S23, when it is determined that the door open / close detection part 8b is off, either of the door open / close detection parts 8a and 8b is on, and which is off. That is, in the door open / close detection parts 8a and 8b, the opening and the closing are mixed. In this case, it is determined that the door 1a is partially open and is in a closed or abnormal state. In step S27, the voice report B is performed by a voice such as "the door is not completely closed". After the audio report B is performed, the flow of the door open / close state report ends.

In addition, when the flow of door open / close state reporting ends when the door 1a is not judged to be closed, the flow of door open / close state reporting may be started again, and the operation of the dishwasher 40 is stopped. You may be. In any case, since the door 1a is not completely closed, the operation of the dishwasher 40 is not started.

In addition, when it is determined in step S26 that the door open / close detection unit 8a is turned on, the door 1a is determined to be completely open, the audio report is omitted, and the flow of the door open / close state report ends. That is, although it is determined in step S22 that the door open / close detection unit 8a is off, in step S26, it is determined that the door open / close detection unit 8a is on this time. Therefore, it is determined that the operation of the door open / close detection unit 8a is unstable, it is determined that the door 1a on the safety side is completely open, and the flow of the door open / close state report ends.

Moreover, the control example of the door opening / closing state report was demonstrated about the structure which the door opening / closing detection part 8 has two door opening / closing detection parts 8a and 8b. However, the door open / close detection unit 8 is not necessarily limited to two. When there are more than two door opening / closing detection parts 8, the determination of each door opening and closing detection part 8 is performed sequentially, and whether the door 1a is fully open or fully closed, or it is partially closed. It is determined whether or not it is processed. In addition, reports may be executed based on these determination results.

According to the present invention, the start input unit receives the start of operation of the main body, the door open / close detection unit detects the open / closed state of the door, the report unit reports the state of the main body using at least voice, and the control unit inputs the start input unit. When the door opening and closing detection unit detects, the report volume is adapted to the user's wishes or the environment by the configuration of changing the report content by the report unit in accordance with the detection state and is easy to use. A dishwasher is provided.
