It is now possible to issue commands to indicate failures of combustion equipment.

[0020] The operation command unit 21 controls the display unit 18 and the memory in response to commands input from the command input operation unit 22. 23 and the failure location indicating section 24, and in response to the instruction, the communication section 20 and a remote control 12 to communicate with the control device 2 of the combustion equipment.

[0021] The memory 23 has a memory part 23a and a reference part 23b, and the memory part 23a has a memory part 23a and a reference part 23b. Memorize the structure diagram of the vessel. Figure 4 shows an example of a bathtub with a water heater. In the case of this bathtub with water heater, the structural diagram shown in FIG. 4 is stored in the memory section 23a. . In addition, in Figure 4, 25 is a bathtub, 26 is a bath pot, 27 is a bath burner, 28 is a water level sensor, 29 indicates the reheating heat exchanger, 30 indicates the hot water heat exchanger, and 31 indicates the hot water burner. .

[0022] The failure location indicator 24 displays the failure code of each part of the combustion equipment and the part overwritten on each part. It is equipped with a comparison table with the address of the failure mark shown on the side of the control device 2 of the combustion equipment. When a failure judgment signal (failure code) is added from the The address of the failure mark is added to the display section 18.

[0023] The display unit 18 displays a graphical representation of the failure location of the combustion equipment in response to commands from the command input operation unit 22. , the display of information stored in the memory 6 of the control device 2, and the information input using the command input operation section 22. Displays correction values, etc.

[0024] Next, the operation of the device of this embodiment will be explained. For example, the fuel used at home When inspecting equipment for failure, bring the monitor device 17 with you and make sure it has a connector. The monitor device 17 is detachably attached to the remote control 12 using the connecting wire 33 provided by the monitor device 17. This is it The monitor device 17 is indirectly connected to the combustion equipment control device 2 via the remote control 12. It becomes possible to communicate. In this state, enter the model of the combustion equipment using the command input operation section 22. When a fault display command is issued, this command is sent to the operation command unit 21 to indicate the fault location. It is applied to the control device 2 via the display section 24, the display section 18, and the communication section 20. Memory 23 is Combustion equipment that is inspected for failure based on the combustion equipment model code specified in the inspection section 23b Find out the structural diagram of Display it on the screen 18a.

[0025] On the other hand, when a failure display command is applied to the control device 2, it is stored in the memory 7. The fault information, that is, the fault code, is read out and added to the fault location indicator 24. Ru. For example, if the sensor signal of the water level sensor 28 of the combustion equipment is abnormal, the failure judgment unit 4, it is determined that the water level sensor 28 has failed, and the code for that water level sensor is It will be stored in the memory 7 as a fault code, and the water level sensor will be sent from this memory 7. This code is added to the failure location indicating section 24 as a failure code.

[0026] The failure location indicating unit 24 detects a failure mark corresponding to the failure code. . In the above example, the address of the fault mark attached to the water level sensor is detected, and the fault mark The address signal of is added to the display section 18. Display unit 18 indicates the failure in the structure diagram of the combustion equipment. Water level sensor 28 as shown in Figure 3 when the fault mark 32 at the position is lit or flashing. Notify of a failure. In addition, in this embodiment, the abnormality is the water level sensor, The current output of that water level sensor is, for example, 5.000 V, and that the current output of that water level sensor is It also indicates in text that the normal specified value is 2.000 to 3.000 V. Ru.

[0027] A malfunction repair worker can tell that the malfunctioning part is the water level sensor just by looking at this malfunction display. You can immediately find out where the water level sensor is installed. Therefore, the trouble can be repaired quickly.

[0028] In addition, the command input operation unit 22 commands the readout and display of data possessed by the control device 2. When doing this, you need to press the button to issue a read command and what data to read. give instructions. For example, in the case of the combustion equipment shown in Figure 4, reading the bathtub water level data When you want to output water, you can issue a command to that effect to import water from the water level sensor 28. The water level data is read out from the memory 6, and the read data is displayed on the display section. Displayed on 18 screens.

[0029] Furthermore, when issuing a data correction command using the command input operation section 22, the command to that effect is , a command as to what data is to be corrected, and a command as to the amount of correction. For example, bath water The temperature detected by the temperature sensor is 2℃ lower than the actual temperature of the bath water. When the hot water is in the bathtub, use the command input operation unit 22 to issue a correction command for bath water and increase the correction value by +2°C. , those command signals are applied to the data correction section 5 via the communication section. Then, the data correction unit 5 corrects the detected temperature of the bathtub water by +2°C to adjust the temperature of the bathtub water. Correct the detected temperature to the correct value. As a result, the bath can be heated to the set temperature correctly. becomes possible.

Check the operation behavior in the dummy state by giving it to the control device 2 This has the effect of being able to do the following. For example, to prevent freezing, For example, when the detected temperature of Inspections of combustion equipment should be carried out if measures are taken to prevent freezing by heating. Even if the contractor goes for an inspection during the daytime when the temperature is relatively warm, the outside temperature is below 0℃. Therefore, check whether the anti-freezing means is working properly. become unable to do so. In this embodiment, in such a case, the outside temperature is input from the command input operation section 22. Enter the outside temperature correction value so that the temperature is below 0℃, or set the outside temperature as By inputting a dummy temperature of minus 1°C, the control device can detect that the outside temperature is below 0°C. It determines that the temperature has fallen and starts anti-freezing operations. Dummy data like this By inputting the This is very convenient because it allows you to check the operation of the system under simulated environmental conditions.

[0031] It should be noted that the present invention is not limited to the above embodiments, and may be implemented in various ways. obtain. For example, in the above embodiment, the memory 23 of the monitor device 17 is The structure diagrams of the various combustion equipment that are used are memorized by model code, but this Even if the storage medium of the memory is inserted from the outside as shown by the broken line in Figure 1, good. In this case, for example, a floppy disk, etc. Structure diagrams and other necessary information can be stored using storage media. By inserting the Operations such as data reading and data correction can be performed. Moreover, the new type When a combustion device is developed and sold, or when the model is changed In the case of 23, write a new structure diagram of the combustion equipment of this new type or model change, or If this writing is not possible, it is necessary to replace the memory 23, but the storage medium In the plug-in method, a new floppy containing structural diagrams of new models and model changes, etc. This can be done just by making it, which is very convenient.

[0032] Further, in the above embodiment, the monitor device 17 was connected to the remote control 12, but this could be connected to the combustion engine. It may also be directly connected to the control device 2 of the device.

[0033] Furthermore, in the above embodiment, a failure mark with a sun pattern is used as a means of notifying the failure location. However, an arrow mark or the like may also be used. In addition, the mark of the failure location can be identified by color. It may be a method.

[0034] Furthermore, in this embodiment, a failure mark was used to notify the location of the failure; The mark is omitted, and the malfunctioning operating part (part or device) itself in the structure diagram is lit, blinking, or covered. The notification may be made using means such as error identification.

[0035] Furthermore, in this example, failure marks are placed on the devices and parts of individual operating parts in the structure diagram. However, one fault mark is used to mark the fault specified in the fault location indicator 24. The fault is displayed by moving the fault mark on the screen to the address position of the fault each time. You may also do so.

[0036] Furthermore, in this example, a gas combustion type water heater, a bathtub with a water heater, a space heater, and a water heater are used. We have explained a monitor device that can be applied to combustion equipment for bathtubs that do not have a Of course, it can also be applied to equipment such as oil-burning water heaters.
