BACKGROUND OF THE INVENTION
The present invention relates to a table stove in which a plurality of stove parts and at least one of these stove parts are provided with temperature and flame detection means constituting a tempura fire prevention device, a falling-off safety device, and the like.
[0002]
[Prior art]
The stove section of the table stove is provided with a combustion state detection means such as a temperature sensor using a thermistor or a flame sensor using a thermocouple, etc., and a magnet solenoid valve that opens and closes the gas flow path to the gas burner These sensors and magnet solenoid valves are connected to the controller, and the controller controls the operating state of the stove according to the detection signal obtained from the sensor. In other words, when the pan bottom temperature obtained by the temperature sensor reaches a predetermined temperature, the controller closes the magnet solenoid valve and extinguishes the gas burner. When the power is reduced, the extinguishing safety device is configured to close the magnet electromagnetic valve and shut off the gas supply.
On the other hand, the above-mentioned stove section is widely used as a two-part type, and in consideration of ease of use, one is a standard burner, the other is a high-heat burner suitable for Chinese cuisine, and one that is installed by changing the heat power on the left and right. There is a tempura fire prevention device using the temperature sensor, one provided on the standard burner side and the other provided on the high thermal power burner side. And because it is safer not to make the wall side a strong thermal burner in consideration of the location of the table stove, the heating power setting of the stove part is reversed left and right so that it can be handled regardless of which side becomes the wall side Of course, in this case, the temperature sensor is also provided on the other side of the stove.

[Problems to be solved by the invention]
This is specifically shown in the internal explanatory diagram of the table stove 20 of FIG. 3, where the top plate and the gas burner are omitted. That is, FIG. 6A shows a type in which the grill portion 20a is at the center and the temperature sensor 24 is provided in the left-side stove portion 22, and FIG. In either case, since the controller 21 is attached to the left inner wall of the table stove 20, in the case of FIG. 5A, the distance between the temperature sensor 24 and the thermocouple 25 and the controller 21 is short, and is indicated by a dotted line. However, in the case of FIG. 5B, since the distance from the controller 21 to the temperature sensor 24, the thermocouple 25, the magnet solenoid valve 26, etc. is increased, the lead wires 27, 27,. It is necessary to extend the length along the gas pipe 28 or the like, and the relay connector 29 or the like is also used. Therefore, the parts and wiring specifications differ between the left and right types in this way, and this leads to an increase in cost at the time of parts manufacture and assembly.
Further, in the table stove 20, high voltage cables 32, 32... Connecting the igniter 30 for ignition and the ignition electrodes 31, 31. In the form of FIG. 3B in which the wiring becomes long, the lead wire 27 such as the temperature sensor 24 is easily affected by the induction noise of the high-voltage cable 32, leading to a decrease in the reliability of the safety device that handles a minute level voltage. . This noise can also occur due to the relay connector 29 interposed.
[0004]
Therefore, the invention according to claim 1 is a table container that can maintain the performance of the safety device without being affected by the noise caused by the high-voltage cable or the relay connector, and can reduce the cost by simplifying the component configuration and assembly work. The purpose is to provide a filter.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory diagram of the inside of the table stove, in which the top plate, the gas burner, etc. are omitted and the internal wiring state is mainly shown. This table stove 1 is provided with stove parts 3 and 4 on the left and right sides of the grill 2 arranged in the center, respectively, where the stove part 3 side is set to the standard heating power and the stove part 4 side is set to the strong heating power. ing. Reference numeral 5 denotes an igniter, from which high voltage cables 7, 7,... Are routed to ignition electrodes 6, 6,. Further, in the stove section 3, a thermistor 8 for detecting the temperature at the bottom of the pan, a thermocouple 9 for detecting the flame of the gas burner, and a flasher 10, and a magnet for opening the gas flow path by pushing the ignition button 11 are opened. An electromagnetic valve 12 is provided. On the other hand, the stove section 4 is similarly provided with a thermocouple 9a and a magnet electromagnetic valve 12a in the flashing device 10a. Here, the thermocouple 9a detects the flame of the gas burner, which are connected in series. A thermocouple circuit is configured in which the magnet electromagnetic valve 12a opened by the push operation of the ignition button 11a is held open by electric power.
And, on the inner surfaces of the left and right side walls of the table stove 1, mounting seats 14a and 14b provided with screw holes are formed at symmetrical positions around the grill 2, and the mounting seats 14a and 14b are respectively The burner controller 13 assembled in the order of the mounting base 13a, the substrate 13b, and the cover 13c can be screwed. The controller 13 is connected to a battery switch 15, an igniter 5, a substrate switch, an igniter switch, or the like provided in the flasher 10 to perform well-known ignition control, or monitor a thermoelectromotive force of the thermocouple 9 to detect a magnet solenoid valve. The tempura fire that automatically extinguishes the heat by shutting off the adsorption current to the magnet solenoid valve 12 when the pan bottom temperature detected by the thermistor 8 reaches a predetermined temperature. This constitutes a prevention device.
[0007]
In the case of the table stove 1 configured as described above, in the case of FIG. 1 in which the thermistor 8 is provided on the side of the stove part 3, if the burner controller 13 is screwed to the mounting seat 14a on the left side wall, the stove part It can be connected to the three-side thermocouple 9 and the thermistor 8 at the shortest distance. On the other hand, when the stove section 3 has a strong heating power, the stove section 4 has a standard heating power, and the thermistor 8 is provided on the stove section 4 side, the burner controller 13 is screwed to the mounting seat 14b on the right side wall as shown in FIG. If it is stopped, this can also be connected to the thermocouple 9a and the thermistor 8 on the stove 4 side in the shortest distance. In this case, the thermocouple 9 on the stove section 3 side is connected in series with the magnet solenoid valve 12. Since the right mounting seat 14b has a slightly narrow space due to the gas pipe 2a to the grill 2, the burner controller 13 is formed by reducing the size in advance in consideration of the mounting here.
Thus, if the mounting seats 14a and 14b of the controller 13 are formed in the vicinity of the left and right kitchen parts 3 and 4, respectively, the mounting position of the burner controller 13 can be selected according to the position of the kitchen part where the thermistor 8 is used. In either case, the lead wires 16, 16,... Of the thermistor 8, the thermocouples 9, 9a, etc. can be separated from the high voltage cables 7, 7,. Accordingly, it is possible to operate the extinguishing safety device and the tempura fire prevention device with high reliability without detecting the influence of the induction noise from the high voltage cable 7. Of course, since the relay connector by extending the lead wire becomes unnecessary, the possibility of the influence of relay noise is also eliminated. In addition, when the controller is on either the left or right side, the lead wires 16 can be connected in the same form without changing the length, so that the wiring work can be simplified and the parts can be shared, leading to cost reduction.
[0008]
In the above-described embodiment, the mounting seats 14a and 14b are provided at symmetrical positions. However, the mounting seats 14a and 14b are not limited to symmetrical positions as long as they can be connected to the left and right with at least the same lead wires. Here, both the left and right sides of the table stove side wall (the upper position in FIGS. 1 and 2) are selected here, but the temperature of the substrate does not rise during combustion of the gas burner, and other members such as gas pipes. As long as the conditions such as not contacting with each other and other members not disturbing the wiring work are satisfied, the front position of the side wall (the lower position in FIGS. 1 and 2), the rear wall, and the like can be selected.
Furthermore, the controller mounting structure may be other than the above-described screw fastening, and the mounting portions may be formed on the left and right with an arbitrary structure.
