[0002]

2. Description of the Related Art FIG. 4 shows various model examples of combustion equipment with a remote controller. (A) of the same figure shows a capacity-switching type water heater, in which the equipment main body is housed in an equipment case 67, and the water entering from the water supply pipe 1 is burned by the burner 2 to generate the hot water heat exchanger 3 When heated, the water is heated to be hot water, and this hot water is guided to a desired hot water supply place such as a kitchen through the hot water supply pipe 4. This kind of equipment is provided with a control device 5, and the control device 5 is connected with a remote controller 14 for setting a hot water discharge temperature, displaying a hot water discharge set temperature and the like via a signal line 62.

According to the operation program, the control device 5 rotates the combustion fan 7 when receiving a water incoming signal from the flow rate sensor 6, and at least the solenoid valve 8 in the gas supply passage 19, the proportional valve 10, and the capacity switching valves 11a and 11b. After opening one side, the igniter electrode 12 is driven to perform point ignition, and after the flame is detected by the frame rod electrode 13, the hot water temperature detected by the hot water temperature sensor 15 becomes the set temperature set by the remote controller 14. As described above, the opening amount of the proportional valve 10 is controlled, and at the same time, the rotation control of the combustion fan 7 is performed according to the combustion amount to control the hot water supply operation. In controlling the hot water supply operation, the control device 5 switches the capacity switching valves 11a and 11b according to the required heat amount.

When the required amount of heat is small, the capacity switching valve 11
When only a is opened, one-sided combustion of the A side of the burner 2 is performed. When the required heat amount is large, the capacity switching valve 11b is further opened to perform multi-sided combustion of the A side and the B side. In the figure, 9 is a fan rotation detection sensor for the combustion fan, 16 is a water temperature sensor, and 17 is a water temperature sensor.
Indicates a water quantity control valve for adjusting the water quantity.

FIG. 4 (b) shows a bath kettle, and the same parts as those of the water heater shown in FIG. 4 (a) are designated by the same reference numerals. This kind of bath can be remote controller 14 etc.
When the reheating operation is commanded, the control device 5 rotates the circulation pump 20 of the reheating circulation pipe 18 to circulate the hot and cold water in the bathtub 21 through the reheating circulation pipe 18. When the running water switch 22 detects the flow of hot water, the control device 5 rotates the combustion fan 7, opens the solenoid valve 8, burns the burner 2 by point ignition, and circulates the hot water circulating through the reheating heat exchanger 23. The water is heated to reheat the hot water in the bathtub 21. And
When the bath temperature detected by the bath temperature sensor 24 reaches the bath set temperature set by the remote controller 14, the reheating operation is stopped.

FIG. 4 (c) shows a compound water heater having a reheating function. The hot water heat exchanger 3 side performs the same operation as that shown in FIG. 4 (a) to perform hot water supply operation. Further, on the reheating heat exchanger 23 side, the hot water in the bathtub 21 is reheated by performing the same operation as that of the bath kettle shown in FIG. This hot water supply and reheating operation are performed by the control device 5, which opens the pouring valve 25 such as a solenoid valve to reheat the hot water produced on the hot water supply heat exchanger 3 side to recirculate the circulation line 18 It is equipped with a function to drop water into the bathtub 21 via the water tank, and pouring water when the water level sensor 26 using a pressure sensor or the like reaches the set water level set by the remote controller 14 or the like. The valve 25 is closed to stop the filling of water, and then the circulation pump 20 is started to perform the reheating operation.

By the way, when inspecting the operating states of the circulating pump of the water heater or bathtub, the actuator such as the combustion fan, and the sensors such as the temperature sensor and the flow sensor, the water heater or bathtub is used. Operate according to the operation program, wait until the operation of the actuator to be inspected and the step operation position of the operation program where the sensor signal is read, check the operating state of the actuator to be inspected, and monitor the sensor output data of the inspection object. Therefore, inspections for the presence or absence of breakdowns were performed manually.

[0008]

However, as described above, when inspecting an actuator or the like of a combustion device, the appliance is operated in accordance with an operation program, and waits until a program position where the inspected actuator or the like operates. Since it must be done, there was a problem that the inspection took too long.

Therefore, the applicant has proposed an inspection system for automatically inspecting combustion equipment such as a water heater. As shown in FIG. 3, this inspection system connects an inspection device 28 to a combustion device 27, and, for example, the detection data stored in the memory of the combustion device 27, such as sensor detection data and actuator operating state data, is inspected by the inspection device side. Read out to store in the memory of the inspection device side, analyze this intake data on the inspection device side to judge the abnormality of the components such as sensors and actuators that make up the combustion equipment, and the judgment result (inspection result) Is informed by the informing unit 40 of the inspection device 28, and the device can be inspected promptly.

FIG. 2 shows a block configuration of a proposed example of the combustion device 27 and its inspection device 28. In the figure, the inspection device 28 is provided with an interrupt control unit 60. The interrupt control unit 60 is a combustion control unit 30 of the combustion device 27.
It has a function of setting numerical values of instrument control conditions and giving commands for inspection, and has a built-in microcomputer.This microcomputer has an interrupt command output unit 31, a data reading unit 32, and a data reading unit. An output unit 33,
SIO port 59, data determination unit 36, data correction unit 37
An external command / drive unit 38, an external response detection unit 39, and a data input unit 42.

The interrupt command output unit 31 has a memory 44 and an operation command output unit 46. The memory 44 stores a program for outputting an interrupt operation command for setting control conditions of the instrument and inspecting various components constituting the instrument. In the proposed example, the interrupt operation command is formed by a password and an aggregate of one or more commands.

The password is a signal indicating the start of the operation command, and the command is a component of the device, for example,
Various sensors such as the flow rate sensor 6, fan rotation detection sensor 9, frame rod electrode 13, hot water temperature sensor 15, incoming water temperature sensor 16, running water switch 22, bath temperature sensor 24, and water level sensor 26 of the equipment shown in FIG. 4, The solenoid valve 8, the proportional valve 10, the capacity switching valves 11a and 11b, the igniter electrode 12, the water quantity control valve 17, the circulating pump 20, the hot water supply valve 25, etc. are used as constituent elements, and the operation commands of each constituent element are encoded and identified. In the proposed example, the commands are classified into the following five types.

The one type of command is for instructing an on / off operation of an operation switch of a remote controller such as a water heater, a bath heater, or a compound water heater with a reheating function. In contrast, a command for CM01 is given, a switch-off operation command for hot water supply operation is given as CM00, a reheating switch-on operation command for the bathtub remote controller is given as CM11, and an OFF operation is also CM1.
The ON / OFF operation command of the switch of the remote controller is given as a coded command, such as 0.

The second type of command is to cancel a desired step operation in the sequence program (operation program) for performing the operation operation of the appliance, and by issuing this command, a predetermined combustion operation of the appliance is given. This means that the program operation is canceled, and when the operation check of the appliance is performed according to the combustion operation program, the unnecessary program operation can be omitted and the operation such as the check can be completed in a short time.

The third type of command is for instructing the compulsory operation of the equipment. For example, the water amount control valve 17, the actuator such as the pouring valve 25 are compulsorily operated, hot water supply, reheating, and water filling. This is to issue a command to forcibly select the operation mode such as. The fourth kind of command is
It is an operation command that sets the numerical value of the control condition etc. With this command, for example, the hot water supply temperature is set, the maximum and minimum valve opening drive current of the proportional valve is set, and the set water level of the water filling is changed. Or a timer or the like is used to set the time. The final fifth type of command is to read detection data from a sensor or the like, or to read the operating state of each component such as an actuator (monitor command),
For example, with this command, signals of sensors such as the hot water temperature sensor 15 and the running water switch 22 are read, whether the remote control switch is in the on state or the off state,
Alternatively, a state monitor such as whether the burner is in a combustion state or a combustion stop state is performed.

In the proposed example, a password and one or more of these various commands are aggregated to create an interrupt operation command, and the interrupt program stored in the memory 44 of the interrupt command output unit 31 starts with the password. It is created by arranging commands in chronological order using a set of one or more commands, and in the proposed example, this interrupt program is a dedicated program in the interrupt mode for setting the condition of the instrument and checking. It is functioning.
The operation command output unit 46 arranges interrupt operation commands after the password as the same command regardless of the type and model of the appliance, and adds the interrupt operation commands to the data output unit 33.

The data reading section 32 reads the unique data (ID data) of the instrument to be set and the inspection target. This I
The D data includes, for example, specification data such as product type, model, hot water supply capacity, exhaust variation, gas type, inspection standard value, inspection target item, inspection standard and its tolerance, and the like, and this ID data is the ID data input unit 41. The input data is read by the data reading unit 32, and the read data is added to the interrupt command output unit 31 by a key operation of a keyboard, a bar code input, or a card input such as a memory card. ing. The data output unit 33 receives the interrupt operation command from the interrupt command output unit 31 as an interface and S
It is added to the combustion control unit 30 of the combustion equipment 27 through the signal line 29 which is a communication means through the IO port 59.

The external sensor 43 shown in FIG. 2 is a sensor for inspecting and correcting (calibrating) the sensor used in the appliance. For example, the hot water outlet temperature of the water heater shown in FIG. 4 (a). When inspecting the sensor 15 and the flow sensor 6,
An external temperature sensor is attached to a pipeline connected to the hot water supply pipe 4, and an external flow meter is connected to a pipeline connected to the water supply pipe 1. Then, the external command / driving unit 38 detects (reads) the hot water temperature from the external temperature sensor, which is an external sensor.
Issue a command and issue a command to read the detected flow rate to the external flow rate sensor. These commands are performed in response to the operation command of the command output from the interrupt command output unit 31, the signal read by the operation of this external command / drive unit 38 is detected by the external response detection unit 39, and the data determination unit Added to 36.

The data determination unit 36 detects the detection signal (the detected temperature or the detected flow rate in the above example) of the external sensor 43 obtained from the external response detection unit 39 and the sensor 47 in the device 27 which is the same as the detection target.
The sensor detection signals of the hot water temperature sensor and the flow rate sensor in the above example are compared with the external sensor 43 as a reference sensor,
It is determined whether the sensor 47 used in the device 27 is normal. If the difference between the detection value of the sensor 47 used in the instrument 27 and the detection value of the external sensor 43 is within a predetermined allowable range, it is determined to be normal, and if it exceeds the allowable range, it is defective. To determine. Then, when the command of the operation command requests the notification of the determination result, the determination result of the inspection target sensor is displayed on the display unit of the notification unit 40 including the liquid crystal screen and the like. Note that the notification of the notification unit 40 is not limited to screen display, and other forms of notification such as a buzzer and a lamp may be performed as necessary. The notification unit 40 is not necessarily integrated with the inspection device, and the number is not limited to one.

When the command of the interrupt operation command requests data correction, the data correction unit 37 obtains the difference between the detection value of the external sensor 43 and the detection value of the sensor 47 used in the instrument 27. Instrument sensor 47 against external sensor 43
The amount of correction of the deviation is calculated by calculation, and the calculated correction value is transmitted via the data output unit 33 to the combustion control unit 30 on the appliance 27 side.
Is supplied to. This correction value is written in the setting data memory 54 on the combustion control unit 30 side, the detection value of the sensor 47 is corrected by the correction calculation unit (not shown) on the combustion control unit side, and based on this corrected sensor signal. The combustion operation is controlled.

A combustion control unit which is a control device on the side of the combustion device 27
30 has a built-in microcomputer, and this microcomputer has a data input unit 48, a main operation control unit 50, a command / drive unit 51, a data output unit 52, a memory clear command unit 53, and setting data. It has a memory 54, a mode converter 49, a SIO port 59, and a monitor signal input / output unit 55. The data input unit 48 receives an operation command of an interrupt sent from the interrupt control unit 60 side through the SIO port 59 and the signal line 29, and according to the command request,
It is added to the main operation control unit 50 and the setting data memory 54.

The main operation control unit 50 has a built-in operation program for controlling the normal combustion operation of the appliance 27, and controls the combustion operation according to this operation program.

A conversion table 45 is provided in the main operation controller 50.
This conversion table 45 translates and converts the command code of the interrupt operation command into the actual operation command signal of the component of the instrument. For example, when the code of the command in the operation command is RD40 of the rotational speed reading command of the combustion fan, this code RD40 is translated into an actual operation command signal for detecting the rotational speed of the combustion fan. The conversion table 45 is table data (table data) showing the relationship between the code of each command and the corresponding operation command signal for actual operation.
With reference to the table data, the code of the command given according to the progress of the interrupt program is immediately translated into the actual operation command signal. The table data of the conversion table 45 is given as data corresponding to the address configuration of the memory to which the operation program of the main operation control unit 50 is given and the configuration of the control target element such as the actuator used in the instrument. In this case, the interrupt operation command (command) is converted into an actual operation command of a form adapted to each device. In this specification, the operation command signal is
For example, it may mean a command accompanied by driving of the constituent elements such as a valve opening command, or may mean a command not accompanied by driving such as a data read command.

By the way, in the operation program of the conventional appliance, the operation command of each step of the program is given with the address of the memory as an address. For example, the rotation start command of the combustion fan is given to the address 10 of the memory, the ignition command by the igniter electrode. Is given as an address, such as address 15 in memory. However, in the system in which the address is used as an address unit, the contents of the program are different when the device type and the like are different, so that the operation command of the same component is given to different addresses every time the device type is different. For example, the instruction to start the rotation of the combustion fan is given to address 10 in the memory for some types of equipment, while it is given to address 11 in the other types of equipment. Since the storage positions are different, there is a problem in that when an interrupt program for inspecting an instrument or the like is to be created, a separate program must be created for each different instrument model or model.

In the proposed example, in order to solve such a problem, an interrupt program for operation command output is created by using the operation of each element constituting the instrument as a command. Therefore, according to the interrupt program for operation command output of the proposed example, when inspecting an instrument and setting numerical values of control conditions, if one interrupt program is prepared, the same inspection and control can be performed for instruments of different models. It becomes possible to set the numerical value of the condition, and the combustion control unit 30
By issuing the same command command to the side, the response operation of the same command can be performed.
The mode conversion unit 49 is configured to have a hard switch 68, and when the pin is inserted into the hard switch 68, the hard switch 68 is turned on and outputs a mode switching signal when the loop path is closed. A switch-off signal is output when the hard switch 68 is turned off and the loop path is opened.

The main operation control section 50 sends a mode switching signal from the mode conversion section 49, that is, when a pin is inserted into the hard switch 68 and the loop path is short-circuited, the operation mode is changed from the operation mode according to the operation program to the interrupt operation command. Switching to the interrupt mode to operate is performed. By this mode switching, the main operation control unit 50 performs operation control according to the command request of the interrupt operation command. On the other hand, when the main operation control unit 50 is operating in the interrupt mode, the mode conversion unit 49
When the switch-off signal is applied from, that is, when the pin of the hard switch 68 is pulled out, the operation mode is switched from the interrupt mode to the operation mode.

The memory clear command section 53 stores data in the setting data memory 54 when a switch-off signal is applied from the mode conversion section 49, that is, when the operation mode of the main operation control section is switched from the interrupt mode to the operation mode. Outputs a memory clear command.

The setting data memory 54 is composed of an erasable and erasable non-volatile memory such as an EEPROM. This setting data memory 54 is operated by the data setting command of the command included in the interrupt operation command during the operation in the interrupt mode. It stores setting data that should be retained without being erased and data such as dummy temporarily stored for inspection. Then, when the memory clear command is issued from the memory clear command unit 53, the data that does not need to be stored and retained is erased.

The controlled element 56 constitutes the device 27,
For example, it means an actuator such as the solenoid valve 8, the proportional valve 10, the capacity switching valves 11a and 11b, the water amount control valve 17, and the circulation pump 20 of the device shown in FIG. When the command of the interrupt operation command commands the drive operation of the controlled element, the command / drive unit 51 drives the controlled element 56 according to the command request. For example, when the command of the operation command requests the rotation start of the combustion fan 7, the rotation start of the combustion fan 7 is performed according to this request.

The monitor signal input / output unit 55 detects the sensor to be monitored based on the monitor command of the command included in the operation command.
The detection value of 47 is read, and this read signal is supplied to the data output unit 52 or stored in the setting data memory 54 in response to a command request. The data output unit 52 receives the monitor signal applied from the monitor signal input / output unit 55 through the signal line 29 and the SIO port 59, which are communication means, and the interrupt control unit 60.
Signal processing according to the command, for example, data determination by the data determination unit 36 and data correction by the data correction unit 37 as described above are performed, and monitor data is displayed on the notification unit 40, for example, a message is displayed. Displayed by.

By the way, the combustion control unit 30 of the combustion device 27
Signal communication with the interrupt control unit 60 of the inspection device 28 is performed by a signal having a rectangular waveform, that is, a digital signal, via the SIO port 59 and the signal line 29. Further, the combustion control unit 30 and the remote controller 14 are each provided with a standard port 58, and the combustion control unit 30 and the remote controller 14 communicate with each other through the standard port 58 and the signal line 62 by a sine waveform signal, that is, an analog signal. Is done.

The proposed example is constructed as described above. Next, an operation example in the inspection of the instrument will be briefly described. First of all, combustion equipment (equipment) installed and used in ordinary households
When an abnormality occurs in 27 and the instrument user requests the inspection of the instrument, a service person etc. carries the inspection device 28 and visits the installation place (home etc.) of the instrument, and a plurality of pieces are read from the front cover of the instrument. By removing the screw, removing the front cover, connecting the SIO port 59 of the inspection device 28 and the SIO port 59 of the combustion device 27 with the signal line 29, and turning on the hard switch 68 of the mode conversion unit 49, The combustion control unit 30 is switched from the operation mode to the interrupt mode.

By advancing the interrupt program in this state, the command for each step operation of the interrupt program is added to the main operation controller 50 of the combustion controller 30 with the password at the head. Then, the command of the interrupt program is converted into an actual operation command signal by the conversion table 45, the main operation control unit 50 by the control operation according to the command request, the operating state and control conditions of the control target element 56 of the appliance 27, For example, the hot water supply temperature of the water heater is set. In this way, the operations required for the inspection and the setting of the numerical values proceed efficiently according to the interrupt program, so that the target control condition setting and the inspection operation are performed extremely efficiently in a short time. And after the inspection,
The inspection device 28 is removed from the combustion device 27, and the front cover of the combustion device 27 is attached to the original device.

In the proposed example, the operation program provided to the main operation control unit 50 of the combustion control unit 30 is used to perform the numerical setting of the control condition and the inspection operation without using the interrupt program. You can That is,
In the proposed example, by outputting the interrupt operation command from the interrupt command output unit 31, the operation according to the command of the interrupt operation command causes the main operation control unit 50 on the combustion control unit 30 side.
Since it is performed by the operation control of the operation command of the main operation control unit 50 according to the operation command of the interrupt, and the unnecessary step operation of the operation program (for numerical setting and inspection of control conditions By outputting a command to cancel (unnecessary step operation), the main operation control unit 50 performs operation control with an operation program in which unnecessary step operation is omitted, and the purpose is to use this shortened operation program. Desired operations such as numerical setting of control conditions and inspection are performed in a short time.

Further, in the proposed example, it is possible to perform operations such as numerical setting of control conditions and inspection without using the interrupt program or the operation program of the main operation control unit. That is, by issuing an interrupt operation command from the interrupt command output unit 31, the operation according to the command of the interrupt operation command is performed on the combustion control unit 30 side, for example, the hot water supply of the water heater of FIG. If you want to monitor the temperature detected by the temperature sensor 15, by adding an interrupt operation command with the command for reading the signal of the hot water temperature sensor to the combustion control unit 30 side, the combustion control unit 30 side can add this command to this command. By performing the operation according to
The temperature detected by the hot water temperature sensor 15 is displayed on the notification unit 40, and the hot water temperature sensor can be monitored by this display. Further, when it is desired to change the valve opening amount of the water amount control valve 17, by adding a coded variable valve opening amount operation of the water amount control valve 17 to the combustion control unit 30 side as a command, the water amount control valve by the instructed amount. The valve opening amount of 17 is variable.

As described above, in the case where the operation command of each constituent element of the combustion device is issued on a one-off basis, the external input means of the interrupt command shown in FIG. 2 (for example, keyboard, card, bar code, personal computer, etc.) is used. By inputting the encoded command using the input means) 63, this command is added to the combustion control unit 30 side, translated by the conversion table 45, and the operation according to the command can be performed.

By the way, in the above proposed example, the combustion equipment
When inspecting the operation state of 27, as described above, unless a serviceman or the like removes the plurality of screws from the front cover of the instrument and removes the front cover, the combustion control unit 30 of the combustion device 27 and the inspection device 28 Can not be connected, and after the inspection, the front cover must be attached again with multiple screws,
There is a problem that it takes time to attach and detach the inspection device 28 to and from the appliance control device (combustion control part).

Further, the equipment is not always installed in a place where it can be easily inspected. For example, when a serviceman asks for inspection of the equipment, the equipment is installed on the wall surface on the second floor. Without tools, it is impossible to inspect the equipment, and it is necessary to prepare a ladder etc. and start again, or there is a problem that it is dangerous because it is work at a high place.

The present invention has been made in order to solve the above problems, and an object thereof is to attach an external inspection device for inspecting an instrument to a device to be inspected with a remote controller which can be attached / detached without taking a space. It is to provide a combustion device.
