[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
If the heater keeping switch 102 is operated, the combustion control unit 103 outputs to the heater control unit 104. On the basis of this signal, the heater control unit 104 controls the heater warm display unit 10.
5, the heater control unit 104 turns ON or OFF the heater 106 in response to the output from the heater temperature detection unit 107 which detects the temperature of the vaporization heater 106 while performing the lighting output.
An FF signal is sent to keep the vaporization heater 106 warm. Thereby, the preheating time of the heater is shortened, the time from ON of the operation switch 101 to the ignition is shortened, and the output is sent from the combustion control unit 103 to the combustion unit 108 for combustion.

[0003]

However, the above-described conventional apparatus which can ignite in a short time is popular because it shortens the waiting time until the ignition, but the power supply to the vaporization heater 106 can be performed even when the apparatus is not operating. There was a problem that the economy was poor. In particular, this type of combustion apparatus is provided with a timer operation function for starting combustion at a preset time. However, when the timer is set at the time of setting the timer operation, the combustion is intended to start combustion after a predetermined time. Although it is not necessary to energize the vaporization heater 106 from the beginning, it is energized,
It wastes power. In addition, as in the above, some types of combustion devices have a function of automatically stopping combustion when room temperature reaches a set temperature and automatically restarting combustion when the temperature falls below the set temperature. In such a combustion device, when the combustion is stopped at room temperature, the vaporization heater 106 does not need to be energized, but is energized, and wasteful power is consumed.

The present invention has been made in view of such a problem, and has as its object to suppress wasteful power consumption and improve economic efficiency.

[0005]

In order to achieve the above object, the present invention provides a heater insulation switch, a timer operation unit,
The combustion control unit includes a heater insulation display unit and a combustion control unit. When the heater insulation mode is selected by the heater insulation switch, the heater insulation operation and the heater insulation operation are performed according to the presence or absence of a timer waiting signal from the timer operation unit. so as to change the state of the display, when the timer waiting signal is present gives an off instruction to the heater insulation display unit together with the issue deenergization instruction to vaporization heater to the heater controller and a heater holding
Even if the temperature switch is operated, it does not accept the warming mode,
When there is no timer wait signal, a lighting instruction is issued to the heater heat retaining display unit, and the heater warming operation or the heater normal heating operation is selected according to the presence or absence of the operation start signal,
Alternatively, a heater insulation switch, a room temperature detection unit and a temperature setting unit, a heater insulation display unit, and a combustion control unit are provided.
The combustion control unit issues a lighting instruction to the heater heat retention display unit when the heater heat retention mode is selected by the heater heat retention switch, and changes the state of the heater heat retention operation according to the presence or absence of the automatic combustion stop signal by the room temperature control. Before
When there is an automatic combustion stop signal, the vaporizer temperature drops.
Also, it is configured not to perform the heat retention operation, and to select the heater heat retention operation or the heater heating operation according to the presence or absence of the operation start signal when there is no automatic combustion stop signal.

[0006]

According to the present invention, the above-described structure allows the heater to be kept warm.
In addition to realizing short-time ignition , the power supply to the vaporization heater is stopped at the time of waiting for the timer during the timer operation or at the time of the automatic combustion stop which stops the combustion in relation to the room temperature, thereby preventing wasteful power consumption. .

Accepts and stops current time setting, timer time setting, and timer operation. Further, the combustion control section 4 automatically repeats stop and restart of combustion during operation based on outputs from the temperature setting section 5 and the room temperature detecting section 6. Numeral 7 denotes a heater warming display section, which is turned on when in the heater warming mode, and turned off when not. Reference numeral 8 denotes a heater control unit for controlling energization of the vaporization heater 9 based on the output from the combustion control unit 4, 10 a heater temperature detection unit for detecting the temperature of the vaporizer heated by the vaporization heater 9, and 11 a combustion unit. It is.

Next, the operation of the control device having the above configuration will be described with reference to FIG. Fig. 2
Operation and heat conduction of the vaporization heater 9 when the heater operation is performed.
5 is a flowchart showing a display operation of a heat retention display section 7;
You. First, when the heater warming mode is stopped, a signal is sent to the combustion control unit 4 together with the operation switch 1 being turned on. Since the combustion controlling unit 4 is not in the heater warming mode, a light-off signal is sent to the heater warming display unit 7. Normal heater ON /
A signal for setting the OFF level is sent to the heater control unit 8, and a signal from the heater temperature detection unit 10 is received to control the temperature of the vaporization heater 9 according to the normal heater ON / OFF level. At the same time, the combustion control unit 4 outputs to the combustion unit 11 to perform combustion.

Next, when the heater insulation switch 2 is operated during the stop of combustion to enter the insulation mode, the combustion controller 4 sends a lighting signal to the heater insulation display 7 to turn on / off the heater insulation.
A signal for setting the FF level is sent to the heater control unit 6,
In response to a signal from the heater temperature detector 10, the temperature of the vaporization heater 9 is controlled in accordance with the heater ON / OFF level for keeping the temperature.

In this state, when the operation switch 1 is turned on and the combustion operation is started, the combustion control unit 4 sends a lighting signal to the heater keeping display unit 7 and sends a signal for setting a normal heater ON / OFF level to the heater control unit 6. And receives a signal from the heater temperature detector 10 to control the temperature of the vaporization heater 9 according to the normal heater ON / OFF level. At the same time, the combustion control unit 4 outputs to the combustion unit 11 to perform combustion.

On the other hand, when the timer operation unit 3 is operated to enter the timer waiting state, the combustion control unit 4 sends a light-off signal to the heater heat display unit 7 and stops the control of the vaporization heater 9 even in the heater heat mode. A signal to be transmitted is sent to the heater control unit 8. Then, a signal for stopping the combustion unit 11 is sent. Similarly, when the combustion is stopped, the combustion control unit 4 stops the heater ON / OFF control,
The heat insulation display is turned off, and even if the heater insulation switch 2 is operated, the heat insulation mode is not accepted, and the power consumption due to the energization of the vaporization heater is suppressed.

When the room temperature detected by the room temperature detecting unit 6 becomes higher than the temperature set by the temperature setting unit 5 and the combustion is stopped, the operation is performed according to the flowchart shown in FIG.
