Description

[Detailed Description of the Invention] This invention relates to a control device for a stove with an upper and lower wick.

If a timer is installed in a stove that uses indoor air for combustion, such as a top-and-bottom stove, and the timer automatically starts combustion after a certain period of time, this is usually done by setting the timer at bedtime. Although it is used in such a way that the room is warm when you wake up the next morning, combustion starts while you are still sleeping, creating the problem of oxygen deficiency. For this reason, for example, when combustion is started by setting a timer, the combustion operation of the stove is stopped after about one hour. By the way, with something like this, it is quite possible to wake up during the one-hour combustion period and switch the stove from the temporary combustion state set by the timer to the continuous combustion state. However, when switching from temporary combustion state to continuous combustion state, the power is turned off.
If the fire goes through the wick, the wick may fall and extinguish the fire in a top-and-bottom stove.

This idea was devised to solve these problems, and it is a control for a top-and-bottom wick type stove that can smoothly switch from combustion to continuous combustion by setting a timer without extinguishing the combustion, improving practicality. The purpose is to provide equipment.

Examples of this invention will be described below with reference to the drawings.

A reset relay 7 is connected to a commercial AC power source 1 through a current fuse 2, a stop side contact 3a of a run/stop switch 3, a seismic switch 4, an overheating thermostat 5, and a diode 6 in series. The reset relay 7 includes a surge voltage absorbing diode 8.
are connected in parallel. The normally open contact 7m of the reset relay 7 is connected in parallel to the stop side contact 3a of the changeover switch 3. Further, an abnormally high voltage protection varistor 9 is connected to the power supply 1 via the power supply fuse 2. In addition, the power source 1
The combustion fan motor 12 is connected to the power supply heater 2, the normally open contact 7m of the reset relay 7, the operation side contact 3b of the run/stop switch 3, the first timer contact 10, and the second timer contact 11 in series. ,
The ignition control circuit 13 and the operation display circuit 14 having an operation lamp are connected to each other, and a core fall prevention solenoid 16 is connected via a diode 15.
are connected. The first and second timer contacts 1
The continuous operation side contact 17c of the first operation state changeover switch 17 is connected in parallel to the series circuit of 0 and 11. Note that the timer operation side contact 17t of the first changeover switch 17 is a non-connection side contact. A surge voltage absorbing diode 18 is connected in parallel to the solenoid 16. The ignition control circuit 13 includes a timer circuit 19, a switching contact 20 driven by the timer circuit 19, a gear motor 21 that raises the wick impregnated with fuel, and an ignition 22 that ignites the raised wick. A gear motor 21 is connected in parallel to the switching contact 19 through one contact 20a of the switching contact 20, and an ignition 22 is connected in parallel through the other contact 20b. The timer circuit 19 sets the switching contact 20 to one contact 20a side when not energized, and sets the switching contact 20 to the other contact 20a when energized, for example, about 25 seconds have elapsed.
I am trying to switch it to the 0b side. When the ignition 22 is energized, it operates for a certain period of time. Further, the power supply 1 includes the current fuse 2, the normally open contact 7m of the reset relay 7, the operation side contact 3b of the operation/stop changeover switch 3, the first core contact 10, and the first changeover switch. The first and second timer contacts 10,
A timer motor 24 that drives the motor 11 is connected. Note that the continuous operation side contact 23c of the second changeover switch 23 is a non-connection side contact. A timer display circuit 25 having a timer lamp is connected in parallel to the timer motor 24. The timer motor 24 is connected to an operating knob 27 of a timer operating dial 26 shown in FIG. 2, and the timer time (0 to 12 hours) is set by rotating the operating knob 27 clockwise. I have to. When the operation knob 27 is located in the range of 0 to 12 hours (however, the 0 position is not included), the first timer contact 10 is closed and the second timer contact 11 is open, and the above-mentioned Operation knob 2
7 is located in the range of 0 to OFF (not including the fully loaded position), the first and second timer contacts 10 and 11 are both closed, and the operation knob 27 is turned OFF. When in the position, the first timer contact 10 is open and the second timer contact 11 is closed. The timer motor 24
When energized, the operating knob 27 is rotated counterclockwise as time passes. Further, the time required for the operation knob 27 to rotate through the range is set to, for example, one hour.

In the device according to the embodiment of the present invention configured as described above, the operation/stop changeover switch 3 is connected to the stop side contact 3a.
In this state, when the power plug is inserted into the outlet and the power supply 1 is turned on, the reset relay 7 is energized and its normally open contact 7m is closed to enter standby. For example, if a user sets a timer at 11 p.m. and wakes up at 7 a.m. the next morning, and wants to have the timer burn operation performed one hour before that time, the user should set the operation knob 27 to the 7 hour position, and set the timer to the first, second, and third positions. second changeover switch 17,
23 is set to the timer operation side contacts 17t and 23t, and the operation/stop changeover switch 3 is switched to set it to the operation side contact 3b. As a result, energization to the timer motor 24 is started via the normally open contact 7m of the reset relay 7, the operation side contact 3b of the run/stop changeover switch 3, and the timer operation side contact 23t of the second changeover switch 23. The display circuit 25 displays the timer operation. This state continues until 6am the next morning. and the next morning 6
When the time comes, the operating knob 27 reaches the "0" position and the timer motor 24 closes the second timer contact 11. As a result, energization to the gear motor 21 is started, and the wick impregnated with fuel starts to rise, and at the same time, the combustion fan motor 12
And the core drop prevention solenoid 16 operates.
Further, an operation display circuit 14 displays the operation status. When approximately 25 seconds have elapsed, the timer circuit 19 switches the switching contact 20 from one contact 20a to the other contact 20b, and energization of the ignition 22 is started. This starts ignition of the wick and starts the combustion operation. When this combustion operation continues for one hour, the operation knob 27 reaches the "off" position, the first timer contact 10 is opened by the timer motor 24, and the power supply to the timer motor 24 is stopped. The energization of the ignition control circuit 13, fan motor 12, and core fall prevention solenoid 16 is stopped. In this way, the wick falls, the combustion is extinguished, and the timer combustion operation ends. Therefore, when the user wakes up at 7 a.m. the next morning, the room will be sufficiently warm. Furthermore, even if the person sleeps past 9 o'clock, the combustion operation will be completed in one hour, so there is no danger of oxygen starvation in the room.

Incidentally, the user may wake up during the timer combustion operation before 7 o'clock the next morning. In such a case, the user must switch from the timer operation state to the continuous operation state, but this switching is done by switching the first and second operation state changeover switches 17 and 23 to the timer operation side contact 17.
t, 23t to the continuous operation side contacts 17c, 23c. As a result of this switching operation, the series circuit of the first and second timer contacts 10 and 11 is short-circuited by the continuous operation side contact 17c of the first changeover switch 17, so that combustion will occur regardless of the operation of the timer contacts. The operation will continue. Moreover, this switching operation prevents the wick from falling and combustion to be temporarily interrupted. In addition, this switching operation opens the timer operation side contact 23t of the second changeover switch 23, stopping the power supply to the timer motor 24, and thereby the operation knob 27 stops rotating at the position shown by the dotted line in the figure. , Displays continuous operation status. Furthermore, since switching between timer operation and continuous operation is performed only by two changeover switches, the configuration is simple.

As detailed above, according to this invention, the wick impregnated with fuel is raised and held when energized to perform the combustion operation, and when the wick is de-energized, the wick is dropped to extinguish the fire. When the timer is running, the timer contact is operated to control the current to be energized for a certain period of time after the end of the specified timer time, and when the continuous operation is to be performed, the current is continuously energized regardless of the timer contact's operation.
Switching from a state in which electricity is energized for a certain period of time due to timer operation to continuous operation can be performed without passing through a de-energized state by using the first and second operating state changeover switches that are linked to each other. , to provide a control device for a top-and-bottom wick type stove that can smoothly switch from timer operation to continuous operation without extinguishing combustion, can easily confirm the display of continuous operation, has a simple configuration, and can improve practicality. It is.
