Abstract

PURPOSE:To enable to easily judge whether switch operation is extinguishing operation or igniting operation of a burning apparatus, by providing an indication lamp for indicating that change to burning state is caused by the switch operation. CONSTITUTION:In starting combustion, a switch 3 is pushed. Thereupon, current is passed to an indication lamp 9 via a normally opened relay switch 6 and a normally closed switch 8, and at the same time, current is also supplied to a delay circuit 7. Thus, operation is started. After passing of a certain time from starting of current supply to the delay circuit 7, the normally closed switch 8 is opened and an indication lamp 9 is extinguished. Since a normally closed switch 11 is closed simultaneously with extinguishing of the indication lamp 9, current is supplied to a load controlling circuit 10 for starting combustion. At the same time, a normally opened relay switch 12 is closed and current is supplied to the indication lamp 9. Thus, the lamp 9 is lighted and indicates combustion. In extinguishing the apparatus, on the other hand, the switch 3 is pushed again.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a smoking appliance in which ignition and extinguishment of a burner are performed by repeatedly pressing a push-button switch, that is, by pulses.

Previously, the applicant filed Utility Application No. 11059 (1983-]
As shown in Japanese Patent Publication No. 28570, a flip-flop circuit is provided in the control circuit of the combustion appliance, and the flip-flop 70 is reversed by the pulse output by suppressing the push-button switch, and the combustor or fire extinguisher is operated. Suggested combustion appliances.

However, in this example, when a burn is detected, the combustion indicator lamp lights up, but no display is made during that time, and since the combustion command and the extinguishing command are performed in the same operation, the user is required to give the burn command until the ignition is started. I was unable to confirm where I went. In addition, because of this, the operation of pressing and suppressing the switch every time was repeated, making the operating state unclear, making it extremely inconvenient to use.

The present invention aims to solve the above-mentioned problems, and will be specifically explained below based on an embodiment shown in the drawings.

(1) is a power switch provided on the negative side power line of the step-down transformer (2). (3) is a step-down transformer (2)
This is a push-button switch installed on the power supply line on the secondary side of the device, and the contact is closed by compression. (4) is a control circuit that turns off the relay (IRL) in conjunction with the operation of switch (3), and includes transistors (Ql), (
Q2) constitutes a bistable multivibrator flip-flop circuit (5), connects a relay (IRL) to its output terminal, and presses the switch (3) to generate a pulse Ij flow and converts it into a flip-flop. operation (inversion operation), and when the transistor (C2) is conductive, the relay (IR
I,) is set to turn on. (6) is a normally open type relay switch of the relay (IRL), and the switch (6) is a normally open type relay switch of the relay (IRL).
) are connected in 16 columns with delay circuits (7) between the power lines on the secondary side of the step-down transformer (2), and this delay circuit (7)
) in parallel with the normally closed switch (8) which opens after a certain period of time when the delay circuit (7) is energized and the light emitting diode (A).
A series circuit is connected with the display lamp (9) which has been completed. OQ is also on the secondary side of step-down transformer (2)? This is a load control circuit that controls the negative side of the solenoid valve, igniter, etc. connected in series with the normally open switch 0υ of the delay circuit (7) between the U power supply lines. Q is a normally open type relay switch that closes when the flame detection relay (not shown) in the load side auxiliary circuit is activated by flame detection, and this switch 02J is a normally closed type switch (3) marked 1] 1J. Bypass combustion indicator lamp (9)
It is connected to. Shoden oil; 1 switch (su, switch (

Hereinafter, in the first embodiment, when using the device, first turn on the power switch (]). At this time, power is also supplied to the control circuit (4), but in this case, a charging current initially flows through the capacitor (CO) connected to the transistor (Ql) side, and a voltage drop due to the resistor (R1) causes (at point R1) Since the potential is low, the transistor (C2) remains at A, while the transistor (Ql) is at a high potential (R
A base current flowing from one point brings the device into a conductive state, and this conductive state is maintained. This base current is a resistance (R2
), (R3), and (R4), so the relay (IRI, ) cannot be operated in A. Therefore, when performing burning (χ), it is sufficient to suppress the switch (3), and the pulse current shunted through the capacitor (C1) makes the transistor (9, 2) conductive, and therefore the transistor (Ql
) becomes stable, and the relay (IRL) is activated by the conduction of the transistor (C2). When the relay (IRL) is activated, the indicator lamp (
9) is energized, and at the same time, the delay circuit (7) is also energized and starts operating. After a certain period of time after the delay circuit (7) is energized, the normally closed switch (8) is opened and the indicator lamp (9) is opened.
) goes out. At the same time as this indicator lamp (9) turns off, the normally closed switch 0υ closes, so the load control circuit 00

rr+7. Then, the flame detection relay is activated, the normally open type relay suite f04 is closed, and the indicator lamp (9) is turned on again and the combustion is started by this lamp (9).

To extinguish the fire at v3, press switch (3) 14 times 1
1- Do. At that time, the relay (IRL) turns off due to the inversion of the transistors (Ql) and (C2), and combustion stops +l.
And of course, the indicator lamp (9) does not have a chevron shape, but a flashing light.

By the way, in the conventional example where each command for P burning and extinguishing is issued by repeatedly suppressing the switch (3), the switch (3)
It was unclear whether press 1 [G] was a combustion command or a fire extinguishing command, but according to the embodiment, when the control circuit (4) receives a combustion command, the indicator lamp (9) indicates that the combustion Since the light is first lit and then turned off, it is possible to confirm the switch operation, and it is easy to distinguish whether the light is in the molten state or the extinguished state. Further, in this embodiment, the lamp for confirming combustion is also used as the indicator lamp (9), but it does not necessarily have to be used also, and it may be provided in the monologue. Furthermore, in this actual HM example, we have explained using a normal discreet 1 circuit, but as shown in Figure 2, a microcomputer controls the flip-flop inversion 11p and the indicator lamp turning on and off when a combustion command is received. may be performed by program processing. That is, Qυ′44
Input terminal r-(2) of operation signal on microfun computer
It is connected to the left of the transistor @, which is in a completely cut-off state, and a push-button switch 8 is connected to the human power (2) circuit of the transistor (c).

The flame detection signal is received from the input terminal -C (1) from the flame detection 3/1 (1st eye, ≠).In the microcomputer Qυ, the human power i/:M (2) When the potential of 4'7 j becomes low, the flag is inverted, and if this flag is in the combustion state, the output terminal (2) is temporarily set to low output, and then the output terminal (2) is set to high. If a flame detection signal is input to the input terminal 01, the output terminal r-C
! It is set so that the output is low.

In this embodiment, when the switch (C) is suppressed, the transistor becomes conductive, so the potential at the input terminal (C) decreases.
The flag in the microcomputer Cυ is inverted, and if the flag indicates the combustion state, the output terminal -r-(
The output of (a) goes low, the indicator lamp (c) is temporarily energized, and turns off after the point 11:I'. Then, the output of the output terminal (c) decreases, and the negative 4jJ control circuit (2f
1 starts operating and combustion occurs, and the combustion is k s”f,
Then, the output from the flame detection circuit lowers the output from the 11-degree output terminal, and the indicator lamp (A) turns on to indicate combustion. Then, press the operation switch C7J again during combustion.
Since the 4th river is low, the flag of the microcomputer II Tsukinotsu is reversed, and at this time, if the flag indicates the extinguishing state, the output terminals r・(5) and (a) both become high output and the combustion is stopped. In this embodiment as well, when the combustion state is reached by operating the switch, the indicator lamp lights up and the 4th operation is activated.
