Description

  The present invention relates to a dishwasher, and more particularly to abnormality notification by a display element.

  Conventionally, dishwashers having a large number of display elements such as LEDs in the display section have been provided to the market in response to the multifunctionalization of dishwashers. In such devices, in addition to the normal contents displayed by the display element, various contents are reported by an expression based on a combination of many display elements (for example, see Patent Document 1). ).

  FIG. 6 is a side cross-sectional view of the drawer-type dishwasher described in Patent Document 1. In FIG. 6, the dishwasher is accommodated in the system kitchen K. The dishwasher is provided with a washing tub 102 inside a housing 101 having an opening at the front. The washing tub 102 has a door body 103 that covers the front opening, an upper and lower two-stage tableware basket 105 that houses the tableware 104 is disposed therein, and an upper surface is opened. A cleaning nozzle 106 is rotatably provided below the tableware basket 105, and the cleaning water stored in the cleaning tank 102 is pumped by the cleaning pump 107 and sprayed from the cleaning nozzle 106 to clean the tableware 104. Moreover, the washing tank 102 has a rail 108 below the left and right lateral sides, and is supported by the housing 101 so as to be movable in the front-rear direction.

  An operation unit 109 is provided on the upper portion of the door body 103, and the operation setting for dish washing is performed by the user. A control unit 110 is provided between the cleaning tank 102 and the door body 103, and the control unit 110 controls a series of operations such as a cleaning process, a rinsing process, and a drying process based on operation settings. In addition, the control unit 110 drives a display element of the display unit 112 to be described later, and monitors whether there is an abnormality during operation.

  FIG. 7 is a front view of an operation unit 109 of a conventional dishwasher, and includes a plurality of operation switches 111 and a display unit 112 on which course names and the like are displayed by LEDs that are a plurality of display elements. Normally, the display unit 112 displays the course set by the user for operation by lighting individual LEDs. However, Patent Document 1 discloses that the accumulated operation time is displayed by the operation of an inspection operator at the time of inspection or repair. Specifically, “For example, when the accumulated operation time is 1000 hours or more as a display method, the drying lamp is turned on, when 2000 hours or more, the reserved lamp is turned on, and when it is 4000 hours or more, the standard lamp is turned on. If the lamp is turned on and the lamp is turned on for a little more than 8000 hours, the accumulated operation time can be displayed by the combination of lighting and extinguishing of the four display lamps. The accumulated operation time when the lamp is turned on and the others are extinguished is 9000 hours or more and less than 10,000 hours, and the accumulated operation time can be displayed in detail by increasing the number of display lamps. .

As another usage method of the display unit as described above, an abnormality notification for informing a situation of a defect that occurs during use of the device is conceivable. FIG. 8 is a front view of another conventional dishwasher, and shows the structure of the front door body 113. The door body 113 includes a drawer handle portion 114 at the upper center, an exhaust port 115 on the left side of the drawer handle portion 114, and an operation portion 116 on the right side. FIGS. 9A and 9B each show an operation unit 116 having three operation switches 111, that is, a power switch 117, a start switch 118, and a course selection switch 119, and a display unit 120. FIGS. The number of display elements of the display unit 120 is different from 9 (b). In FIG. 9A, six kinds of course display have six LEDs, and in FIG. 9B, two kinds of course display have two LEDs. FIG. 9B is provided in a device that pursues ease of use through simple operation due to diversification of functions.

  FIG. 10 is a diagram showing the content of an abnormality and the display of the abnormality, classifying the type of abnormality and the content of the abnormality, and showing the display method for each abnormality content according to the difference in the number of display elements. When there are many display elements as shown in FIG. 9A, it is possible to distinguish and notify all the abnormalities by the combination of blinking display elements. On the other hand, when there are only two display elements as shown in FIG. 9B, the combination of blinking display elements is limited, so that both blinks are recognized so that the number of blinks can be recognized. This display is repeated at a predetermined interval. In this case, the number of blinks can be increased corresponding to the number of abnormal contents to be notified, but in actuality, the number of blinks is set to an appropriate number within a range in which the number of blinks can be visually judged (in FIG. Times and continuous blinking), the contents of abnormality notification are classified and displayed.

JP 2011-251034 A

  However, in the conventional configuration, when the number of display elements is small as in the display unit shown in FIG. 9B, practical display methods such as a combination of blinking are limited, and there are a lot of contents to be notified of abnormality. However, the number of items that can be displayed is limited. In such a case, the content of the abnormality to be subdivided in a certain type of abnormality is displayed as a roughly classified abnormality type. For example, in the case of D abnormality in FIG. 10, there are two types of abnormality of the component c: “open and abnormal” and “short and abnormal”. It will be the same display.

  In this way, even if an abnormality is reported on the display unit, it is displayed roughly classified information, so that the details of the abnormality are not transmitted to the user and the inspection operator, and the user and the inspection are inspected. There was a problem that the worker could not take a quick response without obtaining accurate information on the symptoms of the device.

  The present invention solves the above-described conventional problems, and in a dishwasher that reports an abnormality by a display element such as an LED, the content of the abnormality notification is first displayed with the information of the roughly classified abnormality. If the content of the abnormality is subdivided, the details of the abnormality are detailed to the user of the device and the inspection operator by configuring the information to be displayed for the second time. It aims at providing the dishwasher which can alert | report accurately and accurately.

  In order to solve the above-described conventional problems, the dishwasher of the present invention operates based on an operation unit having a switch for setting a driving operation, a display unit for displaying a setting state by a display element, and an operation setting by the switch. And a control unit that drives the display element of the display unit, the control unit monitors whether there is an abnormality during operation, and notifies the abnormality by the display unit when an abnormality occurs. When the abnormality notification is made, it is handled by classifying a large number of abnormalities roughly classified into multiple stages, such as a large classification roughly classifying a large number of abnormalities and a small classification further subdividing the major classification. The contents are displayed and subsequently the contents of the small classification are sequentially displayed in accordance with the classification stage.

  In this way, the structure of displaying the details of abnormality subdivided by multiple displays makes it possible to display the contents of all abnormalities even if the number of display elements is small. On the other hand, it is possible to provide a dishwasher capable of informing the details of the abnormality.

  The dishwasher of the present invention can display the contents of all abnormalities even when the number of display elements is small, and can notify the user and the repairer of the details of abnormalities.

A control unit that drives the display element, and the control unit is configured to monitor whether there is an abnormality during operation, and to notify the abnormality by the display unit when an abnormality occurs, and perform the abnormality notification Sometimes, the classification of the abnormality is roughly classified into multiple stages such as a large classification roughly classifying the contents of anomalies and the above-mentioned major classification, and the contents of the major classification are displayed first, followed by the above-mentioned The contents of the small classification are sequentially displayed according to the classification stage.

  With this configuration, in the information of abnormality notification when an abnormality occurs, the content of the abnormality subdivided by multiple displays is displayed, so that the content of all abnormalities is displayed even if the number of display elements is small. Therefore, it is possible to provide a dishwasher capable of notifying a user or an inspection worker of the details of a detailed abnormality.

  According to a second invention, in the first invention, when the abnormality notification is performed, the control unit first displays the contents of the major classification, and classifies the contents of the minor classification after a predetermined time. The display is sequentially performed according to the above, and a series of these displays is repeated. With this configuration, the user or the inspection operator can acquire detailed abnormality contents from abnormality notifications repeatedly displayed in sequence, and can understand the symptoms of the device.

According to a third invention, in the first invention, when the abnormality notification is made, the control unit first displays the contents of the major classification, and receives an input from a predetermined switch during the display, so that the minor classification is displayed. The contents are displayed, and the next classification is sequentially displayed in response to an input from a predetermined switch in accordance with the classification stage. With this configuration, the user or the inspection operator can acquire detailed abnormality contents from the abnormality notifications sequentially displayed at the timing of performing input by a predetermined switch, and can understand the symptoms of the device.
In a fourth aspect based on the first or second aspect, before the control unit displays the contents of the large classification and the contents of the small classification, the contents to be displayed next on the display section in advance are displayed. The display is configured to identify whether the major classification or the minor classification.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
FIG. 1 is a front view of a dishwasher according to Embodiment 1 of the present invention and shows a door 1 of a drawer type dishwasher. FIG. 2 is an enlarged view of a main part of the dishwasher shown in FIG. 1 and shows an operation unit 4 provided on the upper part of the door body 1. In addition, the basic structure as a dishwasher is the same as that of the past, and is shown by FIG.

  In FIG. 1, the door body 1 is provided with a drawer handle portion 2 at the upper center, an exhaust port 3 on the left side of the drawer handle portion 2, and an operation portion 4 on the right side. A control unit 5 is provided on the back side of the door body 1. In FIG. 2, the operation unit 4 includes a power switch 6, a start switch 7, a course selection switch 8, and a display unit 9. The display unit 9 displays either a standard course or a power saving course set by the user using the course selection switch 8 by using an LED as a display element. Here, only two display elements are used, and the number is relatively small. In addition, the display method by LED is not limited, In FIG. 2, LED illuminates the character from the back side, However, Other methods, such as lighting LED before a character, may be sufficient.

  The control unit 5 controls a series of operations such as a cleaning process, a rinsing process, and a drying process based on the operation setting. Moreover, the control part 5 drives LED of the display part 9, and also monitors the presence or absence of the abnormality during driving | operation. And when abnormality generate | occur | produces during driving | running | working, while performing the predetermined | prescribed operation | movement corresponding to the content of abnormality, it is comprised so that abnormality notification may be performed by the display part 9. FIG.

  However, since there are only two LEDs on the display unit 9 of the dishwasher in the first embodiment as shown in FIG. 2 and there are 13 items of abnormalities to be notified as shown in FIG. The combination of lighting and blinking of two LEDs cannot be displayed. In the present invention, as shown in the first display column of the abnormality display in FIG. 3, first, the types of abnormality are roughly classified and display is performed by nine types of blinking. Next, as shown in the second display column of the abnormality display in FIG. 3, the display is performed by two types of blinking methods corresponding to the detailed abnormality contents.

  FIG. 3 will be described in detail. FIG. 3 is a diagram showing the contents of the dishwasher abnormality and the display of the abnormality in the first embodiment of the present invention, and the stepwise classification for displaying the details of the abnormality and the details of the abnormality are shown. Show. In FIG. 3, “abnormality type” is a large classification in which a large number of abnormalities are classified into nine types. The “abnormality content” is a small classification that classifies abnormalities that can be subdivided in the large classification. In the “abnormality display”, the “first display” is a display on the display unit 9 for notifying the major classification, that is, the type of abnormality. In the first display, the “power saving” LED is turned on for 1 second as a break, and then the entire LED is blinked twice to nine times and continuously (arbitrarily many times) in nine types. The “second display” is a display on the display unit 9 for notifying a small classification, that is, a detailed abnormality content. In the second display, the “standard” LED is turned on for 1 second as a break, and then blinking is performed once or twice. As described above, by displaying the contents of the abnormality classified into the two stages sequentially over the two stages, it becomes possible to notify the user and the inspection operator of the details of the abnormality.

  Although not shown in FIG. 3, if there are three or more subdivisions for the second subcategory, the total number of blinks may be increased accordingly. In addition, if it is necessary to further subdivide the subcategory, create a display for the third and subsequent times, and display it sequentially from the first time to the third and subsequent times. Can be notified.

The operation and action of the dishwasher configured as described above and having a relatively small number of display elements mounted on the display unit will be described below with reference to the flowchart of FIG. FIG. 4 is a flowchart of notification of abnormality of the dishwasher in Embodiment 1 of the present invention. This flowchart starts from detecting an abnormality during stoppage or operation. During stoppage or operation, the control unit 5 constantly monitors the presence / absence of an abnormality and determines the presence / absence of abnormality detection by various signals (STEP 1). When detecting an abnormality (YES in STEP 1), the control unit 5 determines an abnormality notification item based on the type of abnormality and the content of the abnormality in FIG. 3 (STEP 2). Next, the determined item is displayed for the first time. Before any of the nine types blink, the “power saving” LED is turned on for 1 second, and then all LEDs are turned off for 0.5 second. (STEP3).

  Thereafter, the determined item is displayed for the first time (STEP 4). Next, after all the LEDs are turned off for 1 second, the “standard” LEDs are turned on for 1 second, and all the LEDs are turned off for 0.5 seconds (STEP 5). Thereafter, the determined item is displayed for the second time (STEP 6). Thereafter, after all the LEDs are turned off for 1 second (STEP 7), if there is no input from the power switch 6, the process returns to STEP 3, and the first display and the second display of the items determined in accordance with the abnormality content are repeated. For example, in the case of the E1 abnormality of FIG. 3, it is displayed in STEP 4 with all blinks six times, and in STEP 6 with all blinks once. Further, taking the case where the type of abnormality is C abnormality as an example, all four blinks are displayed in STEP 4 and there is no display in STEP 6. Finally, when the power switch 6 is input (YES in STEP 8), the abnormality notification mode is exited and the power is turned off (STEP 9).

  As described above, in the dishwasher of the first embodiment, when an abnormality is detected, an abnormality notification display that roughly classifies the content of the abnormality is displayed for the first time, and the subdivided contents are continuously displayed. By displaying the second time and repeating these series of displays, even if the number of display elements is small, it is possible to display all the contents of many abnormalities, and the user and inspection work The details of the abnormality can be notified to the person. And a user and an inspection worker can acquire detailed contents of abnormalities from abnormality notices repeatedly displayed sequentially, and can understand the symptoms of the device.

(Embodiment 2)
The basic configuration of the dishwasher in the second embodiment of the present invention is the same as the configuration of the dishwasher described in the first embodiment. The difference is that when the control unit performs abnormality notification, the contents of the major classification are displayed first, and then the contents of the minor classification are displayed sequentially according to the classification stage, and the flowchart is different. .

  The operation and action will be described below with reference to the flowchart of FIG. FIG. 5 is a flowchart of abnormality notification of the dishwasher in the second embodiment of the present invention. This flowchart starts from detecting an abnormality during stoppage or operation. During stoppage or operation, the control unit 5 constantly monitors the presence / absence of an abnormality and determines the presence / absence of abnormality detection by various signals (STEP 1). When detecting an abnormality (YES in STEP 1), the control unit 5 determines an abnormality notification item based on the type of abnormality and the content of the abnormality in FIG. 3 (STEP 2). Next, the determined item is displayed for the first time (STEP 3). Next, except for the power switch 7 which is a key for turning off the abnormality notification, for example, the course selection switch 8 is pressed (Yes in STEP 4), and if the abnormal content is subdivided (YES in STEP 5), it is determined. The item is displayed for the second time (STEP 6).

  For example, in the case of the E1 abnormality of FIG. 3, it is displayed in STEP 3 with all blinks six times, and in STEP 6 with all blinks once. Further, if the type of abnormality is C abnormality, for example, it is displayed in STEP 3 with all blinks four times, and even if the course selection switch 8 is pressed (Yes in STEP 4), the abnormality content is not subdivided content. Therefore (NO in STEP5), the display is turned off (STEP7). Finally, when the power switch 6 is input (YES in STEP 8), the abnormality notification mode is exited and the power is turned off (STEP 9).

As described above, in the dishwasher of the second embodiment, when an abnormality is detected, the abnormality notification display in which the content of the abnormality is roughly classified is displayed for the first time, and then the abnormality notification display is not turned off. It is possible to display all of the contents of many abnormalities even when the number of display elements is small, because it is configured to display the subdivided contents for the second time by inputting a predetermined switch. Thus, it is possible to notify the user and the inspection worker of the details of the abnormality. Then, the user or the inspection operator can acquire the details of the abnormality from the abnormality notification sequentially displayed at the timing when the input is performed by the predetermined switch, and can understand the symptom of the device.

  As described above, the dishwasher according to the present invention can display the contents of all abnormalities even if the number of display elements is small due to the structure of displaying the contents of abnormalities subdivided by multiple displays. Therefore, it is possible to notify the user and inspection workers of the details of abnormalities, and in particular, with the diversification of functions, the device pursues ease of use through simple operation with fewer display elements. Useful.
