Description

[Detailed Description of the Invention] This invention relates to a heater, and more particularly to a heater in which an openable and closable lid is provided on an exhaust section for discharging hot air from a heat source such as a gas burner.

In the above heater, it is not preferable to ignite the heat source with the exhaust passage closed with the lid.

As shown in FIG.
When the lid F is open, the switch C closes in conjunction with a lid F that can be opened and closed.
It is known that the switch C is opened when the lid F is closed (for example, the switch C is opened in 1983).
No. 53218). Note that B is a power source and G is an ignition switch. According to this, when the lid F closes the exhaust part E, the switch C interposed in the circuit A is open, so even if the ignition switch G is turned on, the sparker S will not operate and the heat source D will not operate. Don't ignite it. However, in this case, since I had operated the ignition, I naturally assumed that the ignition would ignite, and after a while I realized that it had not ignited, which caused the inconvenience.

Therefore, this invention proposes a heater that does not have the above-mentioned disadvantages, and will be described in detail below with reference to the drawings. In FIGS. 2 and 3, reference numeral 1 denotes a heat source such as a gas burner, and a discharge section 2 from which hot air is discharged is provided with a lid 3 that can be opened and closed. 4 is an ignition control knob for igniting the heat source 1;

Reference numeral 5 denotes a notification member such as a buzzer, a lamp, etc., and switches 7 and 8 are interposed in the notification circuit 6.
This switch 7 is controlled in conjunction with the opening and closing of the discharge section 2 of the lid 3, and is closed when the lid 3 closes the discharge section 2, and when the lid 3 opens the discharge section 2. Sometimes it's open. On the other hand, the switch 8 is controlled by the ignition control knob 4, and is closed at the ignition position and opened at the extinguishing position. 9 is a heat source,
Reference numeral 10 denotes an operating pin of the switch 7 controlled by the lid 3. In this example, an ignition sparker 11 is provided in a sparker circuit 12 that shares the power source 9 and switch 8, and is useful for ignition when a burner is used as the heat source 1.

Here, when the lid 3 closes the discharge part 2, if you try to ignite the heat source 1 by operating the ignition control knob 4 to allow gas flow, etc., the switch 8 closes and the switch 7 also closes the lid 3. Since the position is closed, the notification circuit 6 is formed and the notification member 5
is activated, the buzzer sounds, and the lid body 3 is removed from the discharge section 2.
Notify that the is closed.

Next, when the lid body 3 does not close the discharge part 2, the switch 7 is open, so the ignition operation knob 4
Even if the switch 8 is closed by igniting the
is not formed, so the notification member 5 will not operate and the buzzer will not sound. At this time, since the discharge part 2 is not covered by the lid 3, there is no problem even if the heat source 1 is ignited, and there is no need for notification, and the heater can be used.

Since the sparker circuit 12 which shares the power source 9 and the switch 8 with the notification circuit 6 is formed when the switch 8 is turned on, the sparker 11 is activated and the heat source 1 is turned on.
Useful for ignition when used as a burner. Even when the lid body 3 closes the discharge part 2, the switch 8 is turned on and the sparker 11 is activated by the ignition operation of the ignition control knob 4, but according to the following embodiment, such Even better without any problems.

That is, in FIG. 4, the switch 13 controlled by the lid 3 is a double-headed switch, and the notification circuit 6
It is also connected to the sparker circuit 12, and when the lid 3 closes the discharge section 2 as shown, the contact piece 14 of the switch 13 connects with the contact 15 to close the notification circuit 6. At the same time, the sparker circuit 12 is opened. When the lid 3 opens the discharge section 2, the contact piece 14 of the switch 13 connects with the contact 16 to close the sparker circuit 12 and open the notification circuit 6.

Here, when the lid body 3 closes the discharge part 2, when an attempt is made to ignite the heat source 1 by operating the ignition control knob 4 to allow gas flow, etc., the switch 8 closes and the switch 13 closes its contact piece 14. Since it is in contact with the contact 15, a notification circuit 6 is formed and a buzzer sounds when the notification member 5 is activated to notify that the lid 3 is closing the discharge portion 2. At this time, the sparker circuit 12 is open, so the sparker 11 does not operate and ignition does not occur when the heat source 1 is used as a burner.

Next, when the lid body 3 does not close the discharge part 2, the contact piece 14 of the switch 13 is in contact with the contact point 16, so when the ignition operation knob 4 is operated to ignite, the switch 8 is turned on. Therefore, the sparker circuit 1
2 is closed, the sparker 11 is activated and the burner serving as the heat source 1 is ignited. At this time, the notification circuit 6 is open, so the notification member 5 is not activated and the buzzer does not sound.

The lid 3 for opening and closing the exhaust passage 2 of the heat source 1 explained as an example serves as a back guard when it is open, and serves as an excellent interior decoration when it is closed. However, another example is a lid that can be opened and closed at the exhaust part of the heat source of a grill, and which prevents foreign matter from falling into the interior by closing the exhaust part. Of course, this is a good idea, and in this case, it is even more advantageous because the heat source is installed in a location where it is difficult to see.

As explained above, the heater of the present invention is designed so that even if the ignition operation is performed while the heat exhaust part 2 of the heat source 1 is closed with the lid 3 closed, the notification member 5 will notify it and the conventional heater There are no such inconveniences.
