Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an operating state display mechanism for various appliances such as combustion appliances such as water heaters, household electric appliances, and electronic equipment.

(Prior art and its problems) The operation of various instruments is monitored by appropriate operation control means based on sensors installed at desired locations.
Although it has been conventional practice to control and display the operating status on multiple indicators, the conventional display mechanism for abnormal operation of various types of equipment has been to display the operating status during normal operation. In addition to the display that displays the information, there is also a mechanism in which a special display is provided in the event of an abnormality, and the display is automatically displayed on this display, and when an abnormality occurs and the equipment stops, the operator can set up a special display. There is a mechanism that displays the details of the abnormality on an appropriate display when operated.

However, the former mechanism requires a dedicated display in case of an abnormality, which poses problems in terms of value and space for the operation panel, etc., and the latter is cumbersome as it requires special operations. There are drawbacks such as.

(Means and effects for solving the problems) The present invention aims to solve the above-mentioned conventional drawbacks. That is, the present invention will be explained in conjunction with the embodiment shown in FIG. In various devices configured to display on the display devices 3a, 3b, 3c..., the display device 3
Display output means 4 for operating a, 3b, 3c...
A normal data display control means 5, an abnormal data display control means 6, and a switching means 7 are provided as a means for controlling the operation, and the switching means 7 is used to determine whether the operation is normal or abnormal by the operation control means 2. At the same time, the display output means 4 is selectively controlled by the switching means 7 and the normal or abnormal data display control means 5 and 6. An alarm display warning of the occurrence of the abnormality and the contents of the abnormality are displayed on appropriate display devices 3a and 3 via the display output means 4, respectively.
b, 3c, . . . Each means itself can be easily constructed using appropriate circuits, elements, etc. using well-known techniques, and may also be constructed using a microcomputer. Indicator 3a, 3
b, 3c... are also LEDs, electric lights, etc. as appropriate.

Next, the present invention will be described in detail based on an example in which the present invention is applied to a water heater. Fig. 2 shows the operation panel of the water heater, where numeral 10 is the operating switch, 3a is the display, and the switches collectively designated 11 are the bath automatic switch, bath follower switch, etc. This indicates the fire switch and washing water inlet switch, and is 3b.
is a comprehensive list of the corresponding display devices. Reference numeral 12 is the hot water temperature setting switch;
c indicates the display. As shown in the figure, the switch generally designated by the reference numeral 13 is a switch for setting the bath boiling temperature and the amount to be poured into the bathtub, and 3d comprehensively represents the corresponding display. The indicators 3c and 3d are composed of a plurality of display sections to display the degree or amount.

In the above configuration, the operation of the water heater can be started by pressing the operation switch 10,
It can be known that the vehicle is in operation by the lighting of the display 3a. The operating amount of the water heater can be appropriately set using the setting switches 12 and 13, and the setting state can be determined by lighting up one of the plurality of display sections of the display devices 3c and 3d, for example, as shown in FIG. This can be known by the lighting of the fifth display section as shown in FIG. In this way, when the water heater is operating normally, the operation control means 2 controls the sensors 1a and 1.
It is determined whether the operation is normal based on the signals from b, 1c, . Data display section 3
Display on a, 3b, 3c, 3d...

For example, when an abnormality occurs in hot water combustion and the operation control means 2 determines that the operation is abnormal using the sensor 1a, the switching means 7 is activated and the data of the abnormality data display control means 6 is displayed on the display output means. 4, and accordingly, the displays 3a, 3b, . . . which had been displaying normal data will now display abnormal data. Of course, it is not necessary to display abnormal data on all displays, but display abnormal data on the minimum number of displays necessary, and maintain the other displays as normal. Also good. The data displayed on the displays 3a, . . . by the abnormality data display control means 6 is an alarm warning of the occurrence of an operational abnormality and the details of the abnormality. For example, in the case of Fig. 3b, the operation indicator 3a is lit in a state different from the normal state,
That is, the alarm is caused to blink as a warning, and at the same time, any one of the plurality of display sections on the display 3c used to display the hot water temperature setting is lit continuously or blinked to indicate the abnormality. The correspondence between the illuminated display section and the content of the abnormality can be confirmed, for example, using the abnormality content correspondence table shown in FIG. 4, and in this way, the content of the abnormality can be quickly dealt with. Here, the alarm may be displayed on the display in a state different from the normal display state, and this display may be made by blinking other indicators of the display 3a, etc. as appropriate. Further, the display of the abnormality content is also performed on the display 3 according to the type of abnormality content to be displayed.
It may be displayed in any of a, 3b, 3c, 3d, .

(Effects of the invention) Thus, when an abnormality occurs in the equipment, the invention automatically switches the display and displays an alarm of the abnormality on the display that had previously displayed normal data. This has the advantage that the contents can be displayed, and abnormalities can be quickly dealt with. In particular, the present invention has the advantage that it is not troublesome because the content of the malfunction is displayed automatically, and it does not require a dedicated display for displaying the malfunction, which reduces cost increases and simplifies the operation panel. play. The latter effect becomes more pronounced as the number of operational abnormalities to be displayed increases. It goes without saying that the present invention can be used not only for the water heater shown in the embodiment but also for various appliances having a plurality of data display devices.
