The present invention relates to an ignition device for gas appliances such as gas ovens. In particular, the present invention relates to an automatic ignition apparatus for a gas appliance that is configured to automatically ignite the heating means through the ignition means while the gas valve opening and closing means and the ignition control means are simultaneously operated by the operation control means by the closing operation of the door.

In the conventional case, the ignition device of the gas appliance generally arrows the spindle 30 via a knob 31 fixed to the end of the spindle 30 so as to protrude out of the body of the apparatus as shown in FIG. 4. Push in the "L" direction to move the blocking member 32 to open the gas valve 33 and at the same time rotate the spindle 30 through the knob 31 to rotate the waste 34 by a certain angle cock body The gas outlet 35a formed in the 35 and the waste hole 34a coincide with each other so that the gas inlet 34b, the waste hole 34a, and the gas outlet 35a communicate with each other.

Accordingly, the gas supplied to the gas inlet 35b is supplied to the pilot burner along the pilot gas supply pipe through the open guide groove 35c and the waste hole gas outlet.

At the same time, the pilot burner is ignited by the spark generated from the spark plug. At this time, the thermocouple is heated to generate an electromotive force. The generated electromotive force keeps the gas valve open by magnetizing the magnet inside the gas valve, and gas continues to the main burner. At this time, the main burner is a pilot burner. Was ignited by sparks.

Such a conventional ignition device is not only very inconvenient to use because the consumer performs direct ignition by using a knob (ignition cock), and the consumer has to hold the knob for a certain time in order to heat the thermocouple. If it is released before this, there are several drawbacks in use such as ignition failure.

Therefore, the present invention is equipped with the operation control means inlevers 4 for controlling the ignition device in the door predetermined position of the gas machine, in order to solve the conventional drawback as described above and the opening and closing of the door in the body of the device The operation control means is operated via the inlevers 4 by the operation, the opening and closing means inspins 14 for opening and closing the gas passage and the ignition control means inspins 16 for igniting the ignition means. The present invention will be described in detail with reference to the accompanying drawings.

In the ignition device of the gas appliance 18, the knob 3 and the pushing surface 4a are provided at both sides while the bracket 2 having the locking hole 2a is engaged inside the door 1, and the hole is at the middle surface. And the lever 4, which is an operation control means formed with a projection 4b which engages with and engages, and the bracket and the lever are fastened by the fixing means 5 while matching the holes and the projections so that the lever 4 is fixed. The shaft is configured to be able to flow left and right, and the cock is provided with a micro switch 8, a gas inlet 9a, and a gas outlet 9b connected to the spark plug 7 inside the body 6 of the apparatus. The body 9 is mounted to match the lever 4 which is the operation control means, but the guide body 9c is formed in the cock body 9 so that the blocking member 10 is provided on the elastic member 11 to one side thereof. A gas valve 12 connected intactly by a built-in, and on the other side, the release preventing ring body 13 is located in the guide groove 9c. A switch for inserting the spindle 14, which is a fixed opening and closing means, to be operated by the lever 4, which is an operation control means, and actuating the sealing member 15, the elastic member 11 'and the micro switch 8 thereto. By sequentially inserting and fixing the lever 16, the spindle is moved forward through the lever, which is an operation control means, by the closing operation of the door 11 to move the switch member 16 and the blocking member 10 of the gas valve 12. At the same time, as the gas is advanced, the gas is supplied and the micro switch 8 is turned on so that the ignition and heating means are ignited.

Here, the front of the door (1) is formed with a long groove so that the left and right flow of the lever (4). Unexplained reference numeral 17 is a holding member to prevent gas leakage from the cock body, 19 is a pilot burner, 20 is a thermocouple, 21 is a solenoid valve, 22 is a main burner, 23 is a thermostat, 24 is It is a heat detection rod.

Referring to the effect of the present invention configured as described above are as follows. When the gas appliance 18 shown in FIG. 3 is to be used, that is, when the user wishes to place food in the appliance and then cooks it, the knob 3 protruding to the outside of the door 1 is provided. As shown in Fig. 3, when the door 1 is closed in the fixed state, the lever 4, which is an operation control means fastened to the bracket 2 by the fixing means 5, passes through the door. As the pushing surface (4a) of the through contact with the spindle 14 located in the guide groove (9c) of the cock body (9) while penetrating the sealing member (15) and pushes it so that the gas passage, that is, Figure 1 (b) and Likewise, the blocking member 10 (which is in contact with the spindle) of the gas valve 12 that has blocked the guide groove 9c is moved to the gas valve side while contracting the elastic member 11 (Fig. 1 (a). Accordingly, when the gas inlet 9a, the gas outlet 9b and the guide groove 9c are opened as shown in FIG. Since the communication is supplied to the gas sending inlet (9a) in the supplied gas side is a pilot burner (19) ignition means in accordance with the gas supply pipe through the open groove (9c) and a gas delivery port (9b).

At this time. The gas introduced into the guide groove 9c is not leaked by the sealing member 15 and the air holding member 17. In addition, as described above, the switch lever 16, which is an ignition control means fixed to the spindle 14 at the same time as the blocking member 10 is opened by the movement of the spindle 14, is moved by the micro switch 8 by the movement of the spindle. To the micro switch 8 attached to the cock body 9, the spark is generated at the ignition plus 7 of the pilot burner 19 by the power supply, so that the pilot burner 9 is ignited. Lose.

When the thermocouple 20 of the pilot burner 19 is heated and electromotive force is generated after the pilot burner ignition (after 5-7 seconds), the magnet of the gas valve 12 embedded in the guide groove 9c of the cock body 9 As the magnet (not shown) is magnetized, the blocking member 10 of the gas valve 12 is kept open as shown in FIG. Accordingly, as the solenoid valve 21 is opened, gas is supplied to the main burner, which is a heating means, through the main burner gas supply passage, and is ignited by the flame of the pilot burner.

As described above, when the gas valve 12 is opened and the main burner 22 is ignited, the consumer moves the knob protruding out of the door 1 from the "use" position to the "disable" position. The pushing surface 4a of 4) is displaced on the center line of the spindle 14 as shown in FIG. 2 (b). At this time, the spindle 14 is supported between the switch lever 16 and the sealing member 15. By the restoring force of the elastic member 11 ', as shown in FIG. 1 (c), the switch lever 16 is also returned to its original position and turned off from the micro switch 8 so that the spark plug 7 is discharged. Is blocked.

On the other hand, since the ring body 13 inserted and fixed to the spindle 14 is caught on the inner surface of the sealing member 15 while the spindle 14 is in the original position by the restoring force of the elastic member 11 ', the moving distance of the spindle 14 To prevent the spindle from leaving (see Figures 1 (b) (c) and 2 (b)).

Here, the thermal power control of the main burner 22 is controlled by the thermostat (THERMO STAT) 23, the solenoid valve 21, the heat sensing rod 24, that is, the indicated temperature of the thermostat 23 According to the thermal sensing rod 24 to control the amount of gas while controlling the solenoid valve 21 by sensing the heat temperature to adjust the thermal state of the main burner. I briefly explained it for this purpose.)

On the other hand, when the gas appliance is to be stopped after the cooking is completed, if the temperature of the thermostat 23 is set to 0 °, since the heat sensing rod 24 does not detect heat, the solenoid valve 21 is turned off to supply gas. As the pilot burner is extinguished, the electromotive force is not generated in the thermocouple 20 so that the magnetization force of the gas valve is extinguished. That is, as shown in FIG. 1 (b), since the gas passage is blocked and the gas supply is stopped, the heating and ignition means such as the main burner and the pilot burner are extinguished to stop the heating of the apparatus.

On the other hand, since the lever 4, which is the operation control means, is fixed to the fixing means 5 so as to be movable left and right on the bracket 2 that is fastened to the inside of the door 1, the lever is selected when "stop" or "use" is selected. It is operated smoothly around the fixing means, and the protrusions 4b and the holes 2a of the brackets are matched to each other, so that the levers do not flow without artificial force, so the lever can be used more safely.

As described above, the present invention provides a door control operation of the ignition control means in position lever 16 and the opening / closing means pins 14 installed inside the apparatus by installing the operation lever for the gas control door. It is possible to automatically perform the ignition and extinguishing of the main burner by operating as it is a very practical design that can solve the weaknesses such as inconvenient use, which was a factor in the ignition means of the conventional gas appliances.
