Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a safety device for a smokeless roaster equipped with an air purification device for removing generated smoke.

(Prior technology) There is a roaster equipped with a cooking part such as a gas burner in the center of the table, and the smoke that is generated when cooking yakiniku etc., including oil components, can rise and diffuse freely so as not to contaminate the room. The structure is such that the air is forcibly drawn into the exhaust passage provided inside the table, purified by the air purification device provided in the exhaust passage, and then exhausted into the room from the exhaust port at the bottom of the table. was.

For example, as shown in Japanese Utility Model Application No. 60-57331.

(Problem to be Solved by the Invention) However, since high-temperature air such as combustion gas is sucked into the exhaust passage, an abnormality in the exhaust passage may cause the inside of the exhaust passage to become abnormally high temperature, causing a fire or other problem within the exhaust passage. There was a risk of inviting And if gas continues to escape during a fire,
Furthermore, there was a risk that it would encourage the fire and increase the damage.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to detect abnormal temperature rise in the exhaust passage, cut off the gas supply, and stop the air purification device, thereby preventing the occurrence of fire.

(Means for solving the problem) The technical means is to place a roaster in a recess formed on the top surface of the table, and to install a gas burner below it, to direct the smoke generated from the food to the surrounding surface of the recess. The smoke is sucked into the exhaust passage at the bottom of the table from the smoke inlet provided in the table.
In a smokeless roaster that exhausts air outside the table from an exhaust port after being purified by an air purification device 7 provided in an exhaust passage, a temperature sensor is installed in the exhaust passage, and the temperature sensor detects an abnormal temperature rise. In this case, a control device is provided that cuts off the gas supply to the gas burner, stops the air purification device, and activates an alarm buzzer.

(Function) According to the present invention, when some kind of abnormality occurs in the exhaust passage and the temperature rises abnormally, the temperature sensor 49 detects this and activates the control device 59 to control the flow of gas to the gas burner 17. Since the supply is cut off and air purifying devices such as the electric precipitator 31 and the blower 33 are stopped, the occurrence of a fire can be prevented.

Furthermore, since the alarm buzzer 61 is also activated, it is possible to notify surrounding people of an abnormality.

The embodiment of the present invention is constructed as described above, and when the roaster 1 is used, smoke generated from cooking such as grilled meat is removed from the smoke intake port 41 into the exhaust path by the suction action of the blower 33. The air is sucked into the room 10 below through the communication path 42, the upper duct part 24, and the lower duct part 25 through the exhaust port 34 of the air blower ja 33, and is exhausted outside the table main body 2 through the ventilation port 45 of each side plate 7. be done.

When passing through this exhaust path, smoke, dust, etc. are removed by a filter 27, an electrostatic precipitator 31, etc., and the air is cooled and purified by a cooling unit 32.

If the inside of the exhaust passage abnormally rises in temperature due to some abnormality, the temperature sensor 49 detects and operates, and the control device 59 closes the electromagnetic on-off valve 56 and closes the electrostatic precipitator 31, blower m33, etc. The electrical equipment is stopped, and the roaster 1 is then stopped, thereby preventing a subsequent rise in temperature in the exhaust passage and preventing the occurrence of a fire.

In the event that a fire or the like occurs in the exhaust passage, the electromagnetic on-off valve 56 is closed, thereby preventing secondary disasters due to gas leakage. Furthermore, since the electric precipitator 31 and the blower 33 are stopped, it is possible to prevent the supply of fresh air to the fire area, effectively preventing an increase in disasters, and ensuring the safety of the equipment. Further, by sounding the alarm buzzer 61, the people around are alerted and safety can be ensured.

Further, since the temperature sensor 49 is provided in a relatively high temperature portion located in front of the air inflow side of the electric precipitator 31 in the exhaust path, detection efficiency is improved and safety can be improved.

Furthermore, even in the event of a power outage, the electromagnetic on-off valve 56 is operated to close, thereby improving safety.

In addition, since each pilot burner 54, each spark plug 57, and each flame iron 58 are arranged in one place, maintainability such as point arrangement or maintenance can be improved.

In the above embodiments, the frame load 58 is used as the light-off sensor, but a thermocouple may also be used. Alternatively, when the flame of the pilot burner 54 leaves the flame rond 58, it may be recognized that the flame has gone out, and the solenoid on-off valve 56 is activated. It is also possible to adopt a configuration in which the electromagnetic on-off valve 56 is actuated by recognizing that the light has gone out.

(Effects of the Invention) According to the present invention, the rostle is disposed in the recess formed on the top surface of the table, and a gas burner is provided below it, and the smoke generated from the food is absorbed into the smoke intake provided on the circumference of the recess. In a smokeless roaster that sucks air from the mouth into an exhaust passage at the bottom of the table, purifies it with an air purification device provided in the exhaust passage, and then exhausts the air outside the table from the exhaust opening, in which a temperature sensor is installed in the exhaust passage. A control device is installed that cuts off the gas supply to the gas burner, stops the air purification device, and activates an alarm buzzer when the temperature sensor detects an abnormal temperature rise. If the temperature rises abnormally due to some reason, the temperature sensor activates the control device, cuts off the gas supply to the gas burner, and stops the air purification device, preventing the subsequent rise in temperature in the exhaust path. Heat can be prevented and fire outbreak can be effectively prevented. Additionally, the security buzzer can alert people around you, which has the advantage of improving safety.
