Description

  The present invention relates to a dishwasher for washing dishes. More specifically, the present invention detects an input state from a start / pause input means and a door open / close state when the operation is paused or restarted from a pause during operation. The present invention relates to a dishwasher that performs voice notification.

  A dishwasher of this type is already known as illustrated in FIG. 6 (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. The technique which alert | reports is disclosed. 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

  However, in the simple sound notification by the piezoelectric buzzer and the speaker described in Patent Document 1 and the light notification by the light emitting diode, the open / close state of the door and the start / temporary state when the operation is temporarily stopped or restarted from the temporary stop. It is difficult to notify the state of stop input means and abnormal closing of the door.

  For example, it is difficult to understand the content of notifications by notifying the content at the same time as the notification due to differences in the number, interval, and length of notification sounds, the number of blinking light emitting diodes, intervals, and time. Need to get used to it. In addition, as a condition for pausing the operation during driving, the door may be opened, or a pause may be input from the start / pause input means, or a combination thereof may be considered. For example, the door may be opened. When the operation is paused by inputting a pause from the start / pause input means, in order to return from the pause state to the operation state, the door is closed and the start / pause input means is used. You need to enter a restart.

  In addition, when the door is opened and the operation is temporarily stopped, in order to return the operation from the temporary stop state to the operation state, the door may be closed. Since there are a plurality of cases in which the method is restored, the user may be confused.

  Furthermore, there are complicated conditions such as whether the right or left door is closed abnormally with respect to the door closing abnormality that may occur when the door is opened or closed. As described above, improvement is desired regarding the pause state during the operation in a wide variety of ways, the method of returning from the pause state, and the notification of the abnormal closing of the door.

  In addition, the notification sound is easily recognized by the user even in a distant place, but there is a problem that the notification sound is not noticed when it is interrupted by the operation sound, operation sound, or notification sound of other home appliances, and it is difficult to determine which device the notification is made.

  Therefore, the present inventor detects the input state from the start / pause input means and the door open / closed state when the operation is temporarily stopped during the operation of the dishwasher, and notifies the user by voice so as to be intuitive. I thought.

  An object of the present invention is to provide a dishwasher capable of detecting in an easy-to-understand manner the voice by detecting the input state from the start / pause input means and the door open / closed state when the vehicle is paused or restarted from the pause during operation. It is to provide.

In order to achieve the above object, the dishwasher of the present invention has a start / pause input means for starting or pausing operation, a door opening / closing detection means, and a notification means for performing a voice notification. As a control to resume operation after pausing , if the input state from the start / pause input means changes during operation and the operation is paused, there is an input from the start / pause input means resuming control operation, if the detection state of the door opening detection means during the operation was paused operation changes, and a resume control the operation detection state of the door opening and closing detection means is closed, during operation If one of the input state from the start / pause input means and the detection state of the door open / close detection means changes and the other state changes after the temporary stop, the door open / close And a control resumes operation by input has been entered from the start / pause input unit together with the detection state of knowledge means is closed, as a control for performing notification when restarted from the start / pause input means The notification content is changed according to the input state and the detection state of the door opening / closing detection means, and the notification means performs voice notification.

  In such a configuration, when the preliminary work for dishwashing in the dishwasher is completed, the user starts the operation by operating the start input means, opens the door for the purpose of adding dishes during the operation, There is a case where the operation is temporarily stopped by inputting a pause from the stop input means, but when the operation is restarted from the pause of the operation, the control means detects the door open / close detection means and the start / pause input means. The content of the notification is changed by voice according to the input state of the vehicle, so that the user is clearly informed of the difference between the door open / closed detection state and the input state of the start / pause input means when restarting from a pause. The user can return from the paused state to the operating state without any confusion.

When the operation is paused, the notification content is changed according to the input state from the start / pause input means and the detection state of the door opening / closing detection means, and the notification means performs voice notification. In the configuration, when the operation is paused, the control means changes the notification content by voice according to the detection state of the door opening / closing detection means and the input state of the start / pause input means, so that the user can It is possible to clearly recognize the difference between the detection state of the door opening / closing and the input state of the start / pause input means, and it is possible to return from the pause state to the operation state without confusion.

The input state from the start / pause input means and the door open / close detection when there is no change in the input from the start / pause input means and the detection state of the door open / close detection means after a predetermined time has elapsed after the operation is paused. According to a further configuration in which the notification content is changed according to the detection state of the means, and the notification means performs voice notification , the control means when the operation is temporarily stopped after a predetermined time has elapsed after the operation is temporarily stopped. Provides a sound notification according to the detection state of the door open / close detection means and the input state of the start / pause input means , preventing the user from leaving the dishwasher in a pause state for a long time. can do.

  There are a plurality of door opening / closing detection means corresponding to a plurality of locations of the door, and the control means is audible according to whether the detection state of the plurality of door opening / closing detection means is combined with opening and closing. In a further configuration that changes the notification content, the open / closed state of the door is detected at multiple locations of the door by multiple door open / close detection means, which may be affected by the door stagnation or the elastic rebound of the locking mechanism to the closed position. The difference between the detection states of the plurality of door opening / closing detection means corresponds to the fact that the difference in the closed state can be partially achieved, and the control means combines the opening and closing with the plurality of detection states of the door opening / closing. Depending on whether or not there is a change in the voice notification content, when the operation is paused or restarted from the pause, the door opening / closing detection status, whether there is a closing abnormality such that the door is partially open, The input status of the start / pause input means It is possible to clearly communicate to the user to have.

  According to the dishwasher of the present invention, when the operation is paused and restarted, the contents of the notification by voice are changed according to the input state of the start / pause input means and the detection state of the door opening / closing detection means, and Since the difference between the input state of the stop input means and the detection state of the door opening / closing is clearly communicated to the user, the user knows exactly the input state of the start / pause input means and the door opening / closing state when restarting the operation. If there is an abnormality in closing, it can be dealt with immediately, and if there is no abnormality in closing, you can move on to the next operation with peace of mind.

  Also, the difference in the partial opening / closing state at multiple locations of the door is made to correspond to the difference in the detection status of the door opening / closing at multiple locations, and whether or not opening and closing are combined in multiple detection states The content of the notification at the site is changed, and the user is clearly informed of the presence or absence of a closing abnormality such that the door is partially open, so the user is careful about the partial closing abnormality of the door that is often overlooked. Without knowing that there is a closing error, you can immediately respond to it, or you can move on to the next operation with peace of mind.

  Hereinafter, a dishwasher according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5 for the 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. 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 start / pause input means for starting and pausing operation, and a course switch 17 for setting a course. An input means 21 provided with a drying switch 18 for setting a drying time and an operation display means 22 for performing display according to those operations by means of 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 power generated by the power circuit 33.

  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 The 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 tub 2 to the outside of the apparatus, and at the same time, the heater 5 is intermittently 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 and a buzzer notification means 31b are provided, and these are controlled by the control means 34 so that notification by voice or buzzer can be performed.

  Next, a description will be given of a control example of notification at the time of restart after the specific operation shown in FIG. 3 by the control device 12 is temporarily stopped. In step S1, an input from the start / pause input means is made during operation. If it is present or if the detection state of the door opening / closing detection means is open, the operation is temporarily stopped, and the process proceeds to step S2, S3 or S5 depending on the state change.

  If the door is only open, the process proceeds to step S2, waits until the door changes to the closed state again, and when the door changes to the closed state again, in step S4, the notification means informs the operator that “the operation has been resumed” by voice. To resume operation.

  If the state change at step S1 is only a pause, the process waits at step S3 until a start is input again from the start / pause input means, and when a restart is input, the process proceeds to step S4.

  If the state change in step S1 is the door open and temporarily stopped, the process waits in step S5 until there is an input from the start / pause input means again or a change in the detection state of the door open / close detection means is detected. If there is an input from the start / pause input means again in step S5 or if a change in the detection state of the door opening / closing detection means is detected, the process proceeds to step S4, S6 or S8 depending on the change in state. If the state change in step S5 is closing the door and restarting, the process proceeds to step S4. If the state change in step S5 is only the door closed, the process proceeds to step S6, the notification means notifies the user of "Please press the start switch", and waits until the restart is input in step S7. When restart is input, the process proceeds to step S4. If the state change in step S5 is only restart, the process proceeds to step S8, and a notification means informs the user of "Please close the door" by voice, and waits until the door is closed in step S9. If closed, it will progress to step S4 and will complete | finish control of the alerting | reporting at the time of restart after stopping driving | operation.

  Next, a specific control example of notification when the operation by the control device 12 is temporarily stopped will be described with reference to FIG. 4. In step S11, there is an input from the start / pause input means during operation, or When the detection state of the door opening / closing detection means changes to open, the operation is temporarily stopped, and the process proceeds to step S12, S13 or S14 depending on the state change.

  If the door is only open, the process proceeds to step S12, and a notification is made by the notification means such as “The operation has been stopped due to the door opening”. If the change in state is only a temporary stop in step S11, the process proceeds to step S13, and a notification is made by the notification means such as “the operation has been stopped by the temporary stop switch”. If the change in the state in step S11 is that the door is open and temporarily stopped, the process proceeds to step S14, and the notification means notifies the user that the operation has been stopped by the door open / temporary stop switch. The control of the notification when it is temporarily stopped is finished.

  Next, after the operation by the control device 12 is temporarily stopped, when a predetermined time has elapsed and the input from the start / pause input means and the detection state of the door opening / closing detection means are not changed, the notification means informs by voice. A specific control example for performing the operation will be described with reference to FIG. 5. If there is an input from the start / pause input means during operation in step S21, or if the detection state of the door open / close detection means is changed to open, the operation is performed. Is temporarily stopped, and the process proceeds to step S22, S25 or S28 depending on the state change.

  If only the door is open, the process proceeds to step S22. If the door is still open in step S22, it is determined whether or not a predetermined time has elapsed since the operation was temporarily stopped in step S23. If the door is closed, a notification such as “Please close the door” is given by the notification means in step S24, and this series of operations is continued until the door is detected closed in step S22. When it is detected in step S22 that the door is closed, the process proceeds to step S31, and a notification means notifies the user that “driving has been resumed” by voice, and the driving is resumed.

  If it is determined in step S21 that the state change is only temporary stop, the process proceeds to step S25. If restart is not yet input in step S25, whether or not a predetermined time has elapsed since the operation was temporarily stopped in step S26. If it is determined that the predetermined time has elapsed, in step S27, a notification such as “please press the start switch” is issued by the notification means, and this series of operations is detected in step S25 as a restart input. Continue until. If a restart input is detected in step S25, the process proceeds to step S31.

  If it is determined in step S21 that the change in the state is the door open and temporarily stopped, the process proceeds to step S28. If the door does not change to the closed state and the restart is not input in step S28, the operation is temporarily stopped in step S29. It is determined whether or not a predetermined time has elapsed, and if the predetermined time has elapsed, a notification such as “Please close the door and press the start switch” is made by voice by means of notification in step S30. This series of operations is continued until the door close and restart inputs are detected in step S28. When it is detected in step S28 that the door is closed and restarted, the process proceeds to step S31. The notification means informs the user that the operation has been resumed by voice, and the operation is resumed. Then, when there is no change in the input from the start / pause input means and the detection state of the door opening / closing detection means, the control for performing sound notification is ended.

  Further, in the present embodiment, a plurality of door opening / closing detection means for detecting the opening / closing state of the door 1a are provided corresponding to a plurality of locations of the door 1a, such as 8a, 8b,. Depending on the detection state of the means 8a, 8b,..., The door 1a is determined to be completely open, completely closed, or abnormally closed, and when the operation is paused and restarted, depending on the determined state. By performing control that performs voice alerts such as “Please close the door” and “Do not close the door completely, please close it,” the user can Clearly recognizes the door state even if the door 1a is bent or the elastic repulsion of the locking mechanism to the closed position affects the door partially and may cause a door closing error. Yes, you can move on to the next task with peace of mind

  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.

  According to the present invention, the input state from the start / pause input means and the open / closed state of the door can be informed in an easy-to-understand manner at the time of temporary stop during operation or restart from the temporary stop in the dishwasher.
