Abstract

PURPOSE:To obtain a remote operator capable of quick inversion of operating conditions by reading the operating condition of a normally closed switch, when the closing motion of the switch is detected, inverting the operating motions of equipments, integrating the detection times of the closing motions of the switch and causing the equipments to take an inversion stand-by condition wherein the operating conditions can be inverted after given times of detection are reached. CONSTITUTION:A sequence controller 31 applies a detection voltage to each remote controller and detects whether or not the operating switch of a main remote controller 50 is closed at a given time interval. When the closing condition of the operating switch are detected twice, the operating condition is inverted such that, the operation is initiated when the equipment is in a stand-by condition and, inversely, the operation is inverted to the stand-by condition when the equipment is in operation. After the closing condition of the operating switch is detected and the operating condition is inverted, the opening condition of the operating switch is detected and all the detection times of the opening conditions including intervening detection times of the closing conditions are integrated. When the integrated detection times of opening conditions reach a given value of the times, an inversion stand-by condition wherein an inverting operation can be executed is brought about.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a remote control device that includes a plurality of display elements on an operating section that includes an operation switch for instructing to start or stop a device.

[Prior Art] As a remote control device, a switch circuit including a variable resistance circuit and a normally open operation switch (hereinafter referred to as "switch") is installed in an operating section located away from the device to control the operation of the device. They are installed in parallel, and the operation part and the control part are connected with two electric wires, and a voltage with a constant voltage direction is supplied from the control part to the operation part. There are devices that detect changing voltages, determine target control values for devices, and control the start and stop of operation of devices.

In addition, for example, in a gas water heater, there is a first display circuit that displays when the supplied voltage contains an alternating current component and is equal to or higher than a predetermined voltage, and the effective value (effective voltage) of the supplied voltage. A second display circuit that displays when the voltage is higher than a predetermined voltage is provided in parallel with the variable resistance circuit and the switch circuit of the operating section.When the C1 operation starts, the second display circuit displays the operation, and when the combustion starts, the second display circuit displays the operation. It has been considered that each display circuit performs an independent display, such as a combustion display using a display circuit.

In this way, when displaying each display while driving,
While supplying each type of voltage for display, these voltages are interrupted for a minute time at regular intervals to supply only a constant voltage for reading the status of the variable resistance circuit and switch, and during that time, the variable resistance circuit is It is detected by reading the setting status and the open/closed status of the operation switch.

In addition, if you repeatedly operate the switch, and the control unit quickly responds to the switch operation and reverses the operating state and repeats the operation and stop, the supply will decrease when the operation starts. Since the voltage for display by the second display circuit is intermittently supplied accordingly, a pseudo signal similar to that in the case where the supplied voltage contains an AC component is generated, and the second display circuit generates a pseudo signal. In the display circuit No. 1, the alternating current component of this pseudo signal causes combustion to be displayed even though combustion is not actually occurring.

Therefore, when the operating state is reversed in response to the switch, as shown in FIG. Perform inversion (Stellaf 52),
After that, the number of continuous detections of the open state of the switch is counted from among the open and closed states of the switch read at fixed time intervals (step 53), and only when this continues for a predetermined number of times (YES at step 54), the reversing operation is performed. The system enters a possible standby state (step 55) and waits for the switch to close again. On the other hand, if the number of consecutive detections of the switch open state is less than the predetermined number of times (No in step 54).
Then, the number of consecutive detections of the open state of the switch is counted again. If the time does not continue within the predetermined time (No in step 54), the reversal operation between running and stopping is not performed.

[Problem to be solved by the invention 1 However, if the user tries to immediately return the operating state to the original state after reversing it for a month, if the user presses the switch repeatedly in a hurry, the open state of the switch may change. Because the process does not continue, a predetermined period of time corresponding to the time from when the switch is finally stopped until the predetermined number of times is counted has elapsed.
It does not go into reversal standby mode. Therefore, the operating state of the equipment cannot be reversed during that time. For this reason, if the operation is performed in a hurry, there is a problem that the reversing operation will not be performed until a long time has elapsed since the initial operation for reversing was started, which increases the irritation of the user.

The present invention provides a remote control device that includes two display circuits on the operating section that display information based on two types of supply voltages, and a switch for starting and stopping the operation. To provide a remote control device which prevents a blue-light display unrelated to the vehicle from being displayed and which can quickly reverse the operating state in response to a user's request.

[F stage for solving the problem] The present invention provides a first display circuit that displays using a predetermined alternating current component in the supply voltage, and a second display circuit that displays when the effective voltage of the supply chamber is equal to or higher than a predetermined voltage. an operating section that includes a display circuit and a switch circuit including a normally open switch, and in which the first display circuit, the second display circuit, and the switch circuit are connected in parallel; and two electric wires connected to the operating section. is connected to the normally open switch, and supplies an electric current with a constant voltage direction to the operating section in order to read the operating state of the normally open switch.
and a control unit that supplies a predetermined voltage for display by the second display circuit during operation of the device, and reverses the operating state and the stopped state of the Ia device according to the operating state of the normally open switch. In the remote control device, the control unit reads the operating state of the normally open switch at regular intervals, and reverses the operating operation of the device when a closing operation of the normally open switch is detected in a reversal standby state. At the same time, after the device reverses the operating operation, the number of detections of the opening operation of the normally open switch is accumulated, and after the number of detections of the opening operation according to the accumulation reaches a predetermined number, the number of detections of the opening operation of the normally open switch is increased. The technical means is to put the equipment into a reversal standby state where it can perform reversal operations.

In the present invention, the operating state of the normally open switch is read at regular intervals, the normally open switch is closed in the reversal standby state, and as a result of the reading, the closing operation of the normally open switch is detected. When this occurs, the operating state of the device is reversed.

Therefore, the operating state of the device can be reversed with only a short period of operation.

Further, after the operating state is reversed, when the opening operation of the normally open switch is detected, the number of detections is accumulated, and when the accumulated number of detections reaches a predetermined number, the state is set to a reversal standby state.

On the other hand, if the number of times the open state of the switch is detected after the reversal operation is less than the predetermined number of times, the reversal standby state does not occur and the operating state continues.

Therefore, even if the normally open switch J is pressed many times during operation, once it is reversed to the stopped state, the stopped state will continue until the switch detects the open state a predetermined number of times. Since the predetermined voltage for display is not supplied at this time, a pseudo signal for operating the first display circuit is not generated.

On the other hand, if the user quickly presses the switch many times in an attempt to return the operating state to the original state immediately after reversing the operating state, an open state will occur between the closed states of the switch. is detected and the number of times of detection is accumulated, so the device enters a reversal standby state while being pressed again and again, and the operating state of the device is reversed immediately after that when the closed state is detected.

[Effects of the Invention] In the present invention, since the reversing operation is performed when the closed state of the switch is detected, the device can be reliably reversed just by lightly operating the switch.

In addition, the number of times the switch is detected as open is accumulated, and if it reaches a predetermined number of times, it will enter the reverse standby state. When the open state during that time is accumulated and detected a predetermined number of times, the reversal standby state is entered, and the reversal can be performed by detecting the closed state immediately after that.

Therefore, there is no need to stop the switch closing operation and wait for a certain period of time before entering the reverse standby state.
It is possible to give a sense of satisfaction to the user without making the user feel embarrassed.

Furthermore, since the reversal operation after reversal is performed only after a predetermined number of open states have been detected, the voltage for displaying by the second display circuit is supplied intermittently in a short period of time. Therefore, it does not act as an alternating current component for displaying by the first display circuit.

Therefore, no abnormal display is performed in the first display circuit.

Next, the sub remote control 60 will be explained.

As shown in FIG.

When giving priority to the sub remote controller 60, the circuit is closed together with the priority switch S 2 and the priority lamp upper 5 is turned on.

Next, the control device 30 and each functional section of the control device 30 will be explained.

In the control device 30, when the control device 30 is connected to a power line, a power source (5) (not shown) is always operating, and the microcomputer is operating in a standby state.

In the sequence control unit 31, when the control equipment 30 is connected to the power line, it is always in a startup standby state, and the resistor 4
1.41a respectively detected terminals 36.37
and each terminal type between terminals 38 and 39 [VS. , V60, the predetermined operating mode is determined.

In the sequence control section 31, each terminal voltage . , V6°, as shown in Figure 5 or Figure 6, read 0.5 to 2.5V as the set temperature voltage,
3.5-5V is read as disconnection detection type, 0.05
V or less is read as the short circuit detection voltage between terminals 36 and 37 and between terminals 38 and 39.

Also, the terminal voltage V of the main remote controller 501111. For the lowest voltage read as set temperature information, 0.
Even lower than 5V and 0.05 as short circuit detection voltage
0.05□~0.3V higher than V)! Read the pressure as the operation switch operation voltage.

On the other hand, regarding the terminal voltage V6o of the sub-remote controller 611, since the setting temperature voltage of 0.5 to 2.5■ is detected only when the priority switch SW2 is closed, the setting temperature voltage is The time when the sub-remote controller 60 is detected is determined to be the priority use time of the sub-remote controller 60.

Conversely, when the priority switch SW2 is in the open state, the terminal T-voltage gVbo becomes higher than the set temperature voltage of 0.5 to 2.5V, so when 3.5 to 5■ is detected. When the main remote controller 50 is used.

Thus, for the terminal voltage V 611 3.5.~5
When the voltage of In the 1-death state, there is no problem in practice because the controller is not involved.

The operating mode is determined by each terminal voltage. ,V(,o is
2, the connection state or conduction state is determined based on the set disconnection detection type or the set temperature and voltage.

The operating modes include a multi mode in which the main remote controller 50 and sub remote controller 60 are connected together, an automatic mode in which no remote controllers are connected, and a single mode in which only the main remote controller 50 is connected. There is.

The sequence control unit 31 operates in a mode other than the l-operation mode, when operation No. 18 of the operation switch SWI is detected, the sequence control unit 31 enters the operation standby state, and in the automatic mode, the operation standby state is maintained at all times.

In the case of multi-mode, when the operation signal of the operation switch SWI is detected and the operation signal becomes standby, the priority switch S
Based on the terminal voltage V6o of the sub-remote controller 60 equipped with W2, it is determined which remote controller is to be controlled based on the set temperature information, and the set temperature from the selected remote controller is transmitted to the temperature control controller 32. .

In addition, in the operation standby state, it is in the operation special state,
The selected remote controller selection information is transmitted to the display control unit 35.

Note that the sequence control unit 31 applies a detection type JI V rei to each remote controller as described later, and for the main remote controller 50, it checks whether the operation switch SWI is closed or not at intervals of 30m5 by 3mS. Detected.

This detection is very accurate, and the closed state of the operation switch SWI is 2.
When the JJI detection is detected, the operation starts in the operation standby state, and conversely, while the operation is in progress, the operation is stopped and the operation is switched to the operation standby state, and the respective operation states are reversed.

In addition, after detecting the closing operation of the operating switch SWI and reversing the operating state, it detects the open state of the operating switch SWI, and also detects the open state, including when an open state is detected in the meantime. All the times are accumulated, and when the accumulated number of open state detections reaches 8 times, a state of inversion standby in which a reversal operation is possible is entered.

As a result, if the operation switch SWI is not pressed after the closed state is detected twice and the 'C1 operation is reversed, the open state will be continuously detected, so the shortest time from the first time the open state is detected is 231 m5. Once this period has elapsed, an instruction for reversing the operation can be given by the operation switch SW1 at any time thereafter.

In addition, even if you immediately press the operation switch SWI over and over again with the intention of returning to operation after giving an instruction to stop operation from the operation switch SWI while driving, the operation switch SWI will not open. Since the number of detections is calculated by FB and the state is set to a reversal standby state, the operation can be reversed by pressing the operation switch SW1 many times.

This stabilizes the control state and eliminates unnecessary changes in operation.

In the standby state, the power to the drive circuits for driving the blower 12 and multi-valve of the gas water heater 1 is turned on, and when water flow to the heat exchanger 13 is detected by the water flow switch 19, a predetermined flow is activated. Combustion is started by performing ignition sequence control, and when water flow stoppage is detected, combustion is stopped by fire extinguishing sequence control.

In the operation standby state and the operation state, the temperature control section 32 has the following functions:
The set temperature voltage from the selected remote controller is already read before water flow is detected, and the hot water temperature thermistor 25
The amount of heating is determined from the detected temperature information and transmitted to the combustion control section 33.

In automatic mode, the system is always on standby, and when water flow is detected, the temperature is set in advance by a day-lag switch (not shown) at a constant temperature (for example, 42°C, 60°C).
℃ or 75℃) as the set temperature, and in standalone mode, it is ready to start! 3, and in the same way as when the main remote controller is prioritized in the multi mode described above, it operates only according to the operation status of the main remote controller 50, and at this time, the main remote controller 50 is disconnected due to a poor connection, etc. If the connection state is abnormal, such as a short circuit between the two, the automatic mode is activated, and the above-mentioned constant temperature is set as the set temperature.

The combustion control unit 33 controls the blower 12 and the governor proportional valve 23 in accordance with the heating amount determined by the temperature control control unit 32 to change the combustion amount of the burner group 11 to f)IJ#.

Based on the information of the selected remote controller and the combustion information detected by the flame rod 15, the display control unit 35 displays each rung of each remote controller 50, 60 in three types: on, off, and blinking, depending on the respective operating conditions. A control signal for controlling each is sent to the remote control drive circuit ii'840.40a.

Before explaining the control contents of the display control section 35, the remote control drive circuit 40.40 controlled by the display control section 35 will be described.

In the remote control drive circuit 40, each switching transistor 43.45 applies a respective voltage to the terminal 36 only when turned on by a control signal, and when both transistors 43.45 are turned off, voltage is applied from the 5V power supply. Only the voltage of resistor 4 is used as the detection voltage v ram.
2 to terminal 36.

When the transistor 43 that directly supplies power from the 5V power supply and the transistor 45 that directly supplies power from the 12V power supply are both off, the detection voltage V roI from the power supply is determined by the variable resistance in the main remote controller 50. A voltage is applied to the series circuit consisting of the parallel circuit of the circuit 51 and the operation switch circuit 52 and the resistor 42, and the voltage is applied to the terminal 7-36.
Depending on the operating state of the variable resistance circuit 51 in the main remote controller 50, the terminal voltage V is determined according to the combined resistance.

The display control section 35 controls each remote control 50.60 according to the control state of the sequence control W section 31 via the remote control drive circuit 40.40a configured as described above.

The lighting, blinking, and extinguishing of each lamp is controlled depending on the operating status of the gas water heater 1: whether it is in standby mode, whether it is in combustion mode, and whether an abnormality is occurring. Further, a separate display is performed for each remote controller 50, 60 depending on whether or not that remote controller is in a priority state.

The relationship between the display state on each remote controller 50, 60 and the operating state of the gas water heater 1 is summarized in 1k.

Similarly, the short circuit detection voltage between terminals 38 and 39 is 0.0.
If 5V or less is detected, the remote control drive circuit 40
The power supply by each transistor 43a, 45a in a is stopped.

The water flow control unit 34 controls the electric water flow control device 18 based on the temperature information detected by the outlet hot water temperature thermistor 25 to limit the flow rate exceeding the capacity of the water from passing through the heat exchanger 13 by ptL.

Next, the operation of the gas water heater 1 of this embodiment having the above configuration will be explained in the case of multi-mode with reference to FIG. 12.

When the control device 30 is connected to the power line and is in the startup standby state, if the operation switch SW1 of the main remote controller 50 is operated and detected as an operation signal (YES in step 1), the priority switch SW is activated as the operation standby state.
The operation lamp of the remote controller selected according to the setting state of step 2 lights up, and the operation lamp of the non-priority remote controller lights up or blinks (step 2). At this time, if the sub remote controller 60 is selected, the priority lamp L5 lights up together with the driving rungs I and 4.

At this time, as shown in Figure 7, only the detection voltage VRE is applied to the selected remote control at a predetermined period, and while each lamp is blinking or blinking, the user When the hot water temperature is set using the variable resistance circuit of the selected remote control, the terminal voltage corresponding to the resistance value of the variable resistance circuit is read as a set temperature signal (step 3).
〉.

At this time, the detected temperature signal is also read from the outlet hot water temperature thermistor 25, and the combustion amount is determined using these as heating information.

Thereafter, when a hot water tap (not shown) is opened and water flowing through the heat exchanger is detected (YES in step 4), ignition control is performed in a predetermined sequence (step 5) and combustion is started.

At this time, the blower 12 and the governor proportional valve 23 are controlled based on the already determined combustion amount, and combustion is started with the combustion amount according to the set temperature.

When ignition is detected (YES in step 6), the combustion lamps of each remote control are lit (step 7).
.

At this time, if ignition is not detected within a predetermined time (No in step 6), the operation rung is turned off and the combustion lamp is blinked (step 8).

Thereafter, the combustion lamp continues to blink until an off signal is not given by the operation switch SW1 (No in step 9>, YES in step 9 when the operation switch SW1 is operated and an off signal is given), and the combustion lamp continues to blink. The lamp goes out (step 10).

Also, if a misfire is detected during combustion (YES in step 11), the process moves to step 8 and onwards.

After ignition is detected, if misfire is not detected (NO in step 1) and water flow is not stopped (step 1
2: NO〉, repeat steps after Stellagts, and thereafter,
The set temperature and tapped water temperature are constantly read at predetermined intervals, and the combustion amount is determined accordingly.

If water flow is stopped (YES in step 12)
, combustion is stopped and the combustion lamp is turned off (step 13).

After that, if the off signal from the operation switch SWI is not given (NO in step 14), the process moves to step 2 and the operation standby state is resumed.

After combustion is stopped, an off signal is given by the operation switch SWI (YES in step 14);
The operation lamp is turned off (step 15).

In addition, if the instruction to start operation is not given by the operation switch SWI (No in Step No. 1)
, combustion does not start even if water is supplied.

The reversal operation by the tl operation of the operation switch SWI in steps 1, 9, and 14 described above is the 13th
As shown in the figure, the following is done:

In each operating state, it is determined whether or not the closing operation of the operation switch SWI is detected (step 21). If it is detected twice in a row, it is determined whether the
If YES in step 21), the operation is reversed (step 23).

On the other hand, if the closing operation of the operation switch SWI is not detected (No in step 21) or if the closing operation is detected less than twice (No in step 22), the inversion standby state is maintained and two consecutive Wait for the detection of the closing operation.

Note that the two consecutive detections of the closing operation are performed to prevent malfunctions caused by external noise, and basically one detection is sufficient.

After the operation is reversed, it is determined whether or not the open state of the operation switch SWI is detected, and if the open state is detected (YES in step 24), the number of times the open state is detected is accumulated at the start of FM. (Step 25).

Conversely, if the open state is not detected, such as when the operation switch SW1 is kept pressed (No in step 24), the start of integration is waited until the open state is detected.

When integrating the number of detections of the open state, even if the open state is not detected after the start of integration, the detection of the open state is ignored and only the number of detections of the open state is integrated.

As a result, if the number of detections of the open state reaches 8 times (YES in step 26), the reversal operation enters a judicial reversal standby state (step 27), and the process goes to step 21 and thereafter detects the closed state. wait.

If the number of times the open state has been detected is less than eight times (No in step 26), the state waits until the number of times the open state is detected is eight times, and the state is set to an inversion standby state.

Therefore, for example, as shown by the solid line in FIG.
If the operation switch SWI is first operated at time t2 and the operation switch SWl is pressed again and again after performing a reversal operation at time t2, the open state is detected at time t3 and then 8.
Therefore, at the final time t4, a reversal operation is performed and the operating state returns to its original state.

In this case, as shown by line 6 & in FIG. 14, if the operation switch SWI is opened immediately after the reversal operation, the reversal becomes possible at time t5, which is earlier than time t3.

On the other hand, in the conventional case, since the open state needs to be detected eight consecutive times after the user gives up and stops operating the operation switch, there is a considerable delay in entering the inversion standby state.

As described above, in this embodiment, when the operation switch is operated, the reversal operation is performed immediately if it is in the reversal standby state, and even if the user attempts to return to the original operating state immediately after performing the reversal operation, Even if the switch is repeatedly operated, the reversal operation can always be performed during the operation.

In addition, since the open state must be detected at least 8 times to reverse the operation, the power for lighting the operation lamp will not be supplied intermittently in a short period of time, and the combustion lamp will be turned on by a false signal. Never.

In this embodiment, water flow is detected by the water flow switch, but water flow may be detected by a flow rate detection signal from a flow rate sensor.

In the above embodiments, a gas water heater is shown, but a water heater equipped with a combustor that uses other fuels such as petroleum, or a water heater that uses electric heating may also be used, and the device is not limited to a water heater. An air conditioner or the like may be used as long as the remote control device has a display element on its operation section.
