Abstract

PROBLEM TO BE SOLVED: To provide a roaster, equipped with a seismic sensor, responding surely only when the sensor has received earthquake. SOLUTION: A seismic sensor 22 is placed on a floor 19 through a weight 21 under a condition that the sensor 22 is isolated from the table 1 or the casing type frame 20 of a roaster. When earthquake has occurred, the operating signal of the seismic sensor is transmitted to the opening and closing valve of a gas burner through a control circuit 16. According to this method, when drinking and eating men surround the table 1 and they kick the table by feet of them, the vibration of the kicking will not be transmitted to the seismic sensor, whereby the malfunction of the seismic sensor can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roaster used for installing a gas burner substantially above a central portion of a roaster table, cooking food on the burner, and eating and drinking around the table. Things.

[0002]

2. Description of the Related Art Conventionally, the above-mentioned roaster has been used in restaurants and barbecue restaurants. Since a gas burner is used in this roaster, it is desirable that the supply of fuel gas to the gas burner be automatically stopped if an earthquake occurs.

Therefore, like other gas burner-using devices, for example, a stove or a hot air heater, an automatic fire extinguishing measure in which a seismic sensor is incorporated in the roaster and the operation of the sensor stops the refueling of the gas burner. It is possible to take. However, the roaster cannot take automatic fire extinguishing measures as in the known technique.

[0004] This is because the roaster table is not usually fixed to a hard floor, but is merely placed on the floor surface. The table vibrates easily when people kick the table with their legs. In particular, the table is about as tall as an office table, and is therefore more susceptible to vibration than if it were subjected to a lateral load.

The inventors of the present invention have studied a method of mounting a seismic sensor which is sensitive only when the table is subjected to earthquake vibration in the roaster used as described above. The present inventors have found the fact that the seismic sensor can be mounted on the floor via a specific member without directly mounting the sensor on the floor, and completed the present invention. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a roaster including a seismic sensor that reliably responds only to an earthquake.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a gas burner is installed at a substantially upper portion of a table placed on a floor, and food is cooked on the gas burner. In addition, in a roaster adapted to eat and drink around the table, a seismic sensor is placed on the floor via a weight, and a seismic signal of the seismic sensor is transmitted via a control circuit to the on-off valve of the gas burner. Means that can be transmitted to the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. The device of the present invention
As shown in FIGS. 1 and 2, basically, a rectangular table 1 placed on a floor 19, a circular drop 2 provided substantially in the center of the table 1, and a drop 2 A funnel-shaped outer hook 3 locked to the mouth 2, a bottomed cylindrical inner hook 5 concentrically disposed and locked inside the outer hook 3 with a predetermined gap 4 therebetween, It is composed of a gas burner 7 mounted on the bottom 6 of the inner pot 5, a hollow bottomed pan-shaped water tank 8 locked in the inner pot 5, and a rostor 9 installed above the water tank 8. ing.

[0008] In the roaster constructed as described above, when people who eat and drink roast meat on the roster 9 surrounding the table 1, the smoke generated at that time causes the outer kettle 3 and the inner kettle to close the gap 4. 5, through the through-hole 11 of the top ring 10 installed at the upper end portion, enters the gap 4, and then passes through the exhaust pipe 12 of the outer kettle 3, and is installed in the middle of the exhaust pipe 12 (shown in FIG. None) to exhaust air outside.

The gas supply pipe 1 is connected to the gas burner 7.
Fuel gas is supplied from 3. An optical sensor 14 is provided outside the outer kettle 3, and the combustion unit 1 of the gas burner 7 is provided.
When the flame 5 has extinguished, the optical sensor 14 is electrically responsive, and the responsive signal is transmitted to the control panel 16 as a control circuit. Then, an operation signal is sent from the control panel 16 to an on-off valve 17 provided in the middle of the gas supply pipe 13 so that the supply of the fuel gas to the gas burner 7 is stopped. The on-off valve 17 has a knob 1
An on-off valve 17 can be opened and closed by manually operating the knob 18.

Further, in the apparatus according to the present invention, a weight 21 is provided on the floor 19 on which the roaster is installed, inside the casing-like frame 20 which is a component of the table 1. And the seismic sensor 22 is fixed thereon. The signal line 23 extending from the seismic sensor 22 is connected to the control panel 1.
6 (FIG. 2). In the present invention, the “floor” does not mean an unstable floor in which the seismic sensor 22 itself is sensitive to vibration other than the earthquake.

In the roaster having such a structure, when the gas burner 7 is ignited, the casing frame 2
When a plurality of cooks surround the circumference of 0, their legs naturally touch the casing-like frame 20. If the device uses a gas burner that has been conventionally known, a seismic sensor is mounted on the main body of the device. At that time, the seismic sensor operates and the supply of fuel gas to the gas burner stops.

However, in the roaster according to the present invention, the seismic sensor 22 is installed on the floor 19 via the weight 21 and the weight 21 itself is placed firmly on the floor 19. Therefore, when the floor is shaken only by the earthquake, it operates in response to the shake, and the operation signal is transmitted to the control panel 16 through the signal line 23. Then, the on-off valve 17 provided in the gas supply pipe 13 from the control panel 16 is closed, and the supply of the fuel gas to the gas burner 7 is stopped. Even if a person who eats and drinks around the table 1 surrounds and kicks the table 1 with his / her feet, the vibration is not transmitted to the seismic sensor 22, so that malfunction of the seismic sensor 22 can be prevented.

Since the seismic sensor 22 is attached to the weight 21, when the roaster is installed on the floor 19, the seismic sensor 22 is attached to the weight 21 in advance, and the signal line 23 is connected to the sensitive sensor 22. Once connected, the seismic sensor 22 can be easily set on the floor 19 in a non-contact state with the frame 20 simply by placing the weight 21 on the floor.

The present invention can be implemented by partially modifying the above-described embodiments without departing from the essence of the invention and without significantly impairing the effects of the invention. For example, the weight 21 may be made of any material and may have any shape as long as the weight 21 can be set by simply placing the weight 21 on the floor 19.

[0015]

As described in detail above, the present invention has an excellent effect that it is possible to provide a roaster equipped with a seismic sensor that reliably senses only when receiving an earthquake.
