Description

      The present invention relates to a gas stove baking oven used for a gas stove having an automatic fire extinguishing device that cuts off or minimizes the supply of gas when a preset temperature is reached.

      Some gas stoves are equipped with an automatic fire extinguishing device that cuts off or minimizes the supply of gas at a preset temperature. This automatic fire extinguisher is useful for preventing ignition of cooking oil that has been overheated during cooking of fried foods, and also for preventing air-burning. For gas stoves with multiple burners, only one burner should be installed. However, those manufactured after October 2008 are installed in all burners.

          Note that this type of automatic fire extinguishing apparatus has a thermal sensor in which a thermal sensor is erected at the center of a burner as disclosed in, for example, Japanese Patent Laid-Open No. 11-201460, and the thermal sensor is placed on the bottom surface of a pan or the like. The temperature of the bottom surface is detected by contact, and when the bottom surface reaches a preset temperature (about 250 ° C.), the gas supply is automatically cut off or minimized.

When using a burner with an automatic fire extinguisher to burn a fish or salmon, the gas sensor is cut off in a very short time and the fire is automatically extinguished because the thermal sensor is in contact with the saucer of the grill. The supply of gas is minimized and a so-called fire is generated. Since the soup is contained in a pan or the like, the temperature of the bottom surface directly hit by fire does not exceed 100 ° C. even when heated. For this reason, the automatic fire extinguishing device does not operate.
However, in a baking machine, the saucer part does not correspond to soup, and a direct fire is directly applied, so the temperature immediately exceeds 250 ° C. (a preset temperature), so that the fire is automatically extinguished in a very short time. With this, a burner equipped with an automatic fire extinguishing device cannot grill fish and carp using a grill.

          In addition, the inventor considered that such a situation (automatic fire extinguishing in a short time) might be avoided by opening the central part of the saucer part of the pottery, that is, the part where the automatic fire extinguishing device contacts. It was done, but because the edge of the opening was overheated, the automatic fire extinguisher was activated in a short time of about 1 minute, and the fire was extinguished, and then the fire was extinguished when 5 minutes 30 seconds passed.

In order to solve such a problem, a gas net-fired device in which the automatic fire extinguishing device is not activated has been devised (Japanese Patent Laid-Open No. 07-248119). This gas net-fired machine is equipped with a red-hot plate with an open-spaced net on the upper surface and a heat-sensitive sensor springed upward in a sensor protection ring provided in the center of the burner. And a cap-shaped heat insulating cover made of heat-resistant heat insulating material that is detachably attached to the sensor protection ring, and is configured to shut off the gas supply at the output of the thermal sensor. .

          However, as of December 12, 2007, “Safety Measures for Gas Stoves-Amendments to the Enforcement Order of the Gas Business Law and the Act on Ensuring Safety of Liquefied Petroleum Gas and Optimization of Transactions” (Product Safety of the Ministry of Economy, Trade and Industry) Section) “It is legally obligated to install cooking oil overheat prevention devices and extinguishing safety devices for all burners”. The “cooking oil overheating prevention device” is an “automatic fire extinguishing device that cuts off or minimizes the supply of gas when a preset temperature is reached”.

If cooking oil overheat prevention device (automatic fire extinguishing device) is installed in all the burners, the conventional gas stove ware cannot be used.
As long as it is described in Patent Document 2, a gas stove equipped with an automatic fire extinguishing device can be used. However, since the cap-shaped thermal barrier cover must be in close contact with the thermal sensor, the size and shape of the thermal sensor It is necessary to prepare a wide variety according to the situation.

      The present invention was devised in view of the above circumstances, and even a gas stove equipped with an automatic fire extinguishing device can be used stably regardless of the size and shape of the thermal sensor. The purpose is to provide a vessel.

      The stove for gas stove according to the present invention is provided with a saucer part that is inclined so that a gas fire hits upward from the central part along the peripheral part, and a recess is formed in the central part of the saucer part. Characteristically, food is placed on a saucer and heated.

      In the gas stove baking apparatus according to the present invention, the heat is easily transmitted to the outside from the central part of the dish by inclining the tray part. For this reason, the temperature of the part where the thermal sensor contacts during heating, that is, the temperature of the central part of the tray does not rise too much. Therefore, even if the thermal sensor is activated and cooking is not performed sufficiently as in the past, the gas supply is cut off or minimized by the operation of the automatic fire extinguishing device, and it is prevented from becoming a fire. Can be baked.

The experiment was conducted under the following conditions.
As the gas stove, the one provided with the thermal sensor S in all the mouths made by Paloma Industry Co., Ltd. and Rinnai Co., Ltd. was used. These gas stoves are provided with a thermal sensor S which shuts off or minimizes the gas supply at about 250 ° C. Some of these gas stoves can change the operating temperature of the thermal sensor to about 290 ° C.

Experiment 1
First, using a conventional gas stove baking oven, 1 Paloma Kogyo Co., Ltd. 2 Rinnai Co., Ltd. Both of them are burners on the high thermal power side, and the thermal power is set to high fire, with a thermal sensor (operating temperature about 250 ° C) Set.
Measure the temperature of the mesh part at 1 minute and 3 minutes after ignition.
The measurement location is the central part of the net and the peripheral part of the net 1 minute later, central part 44 degrees, peripheral part 40 degrees
3 minutes later 89 ° central area 150 ° peripheral area 2 1 minute central area 104 ° peripheral area 102 °
3 minutes later Central part 98 degree Periphery part 100 degree

Experiment 2
Bake two bowls under the same conditions as in Experiment 1.
1 Finish in 10 minutes ... The wrinkles become soft but do not swell.
10 minutes high fire time is 4 minutes 1 second High fire rate 40%
The net temperature at the end of 10 minutes is 65 degrees
With normal firepower, the firewood can be cooked in about 5 minutes. However, even if the thermal sensor is activated and it takes a long time (10 minutes), the rice cake cannot be cooked sufficiently.
5 and 6 are images of the back and front of the bag at the end.
2 Finished in 10 minutes ... One swelled.
10 minutes high fire time is 3 minutes 15 seconds
The net temperature at the end of 10 minutes is 55 degrees. FIGS. 7 and 8 are images of the back and front of the bag at the end.

      What is found from these experiments 1 and 2 is that a gas stove equipped with the thermal sensor S cannot successfully bake the food with a conventional gas stove baking oven. This is because the saucer portion of the conventional gas stove baking oven is overheated, so that the supply of gas is immediately minimized so that it becomes a fire and the heating temperature is lowered.

Next, an experiment using the gas stove baking apparatus 100 according to the embodiment of the present invention was performed.
Experiment 3
1 Paloma Kogyo Co., Ltd. 2 Rinnai Co., Ltd. Both of them were burners on the high thermal power side, the thermal power was set to high heat, and the thermal sensor was set (operation temperature about 250 ° C.).
Measure the temperature of the mesh part at 1 minute and 3 minutes after ignition.
The measurement location is the center of the net and the periphery of the net 1 1 minute later 41 ° of the central part 180 ° of the peripheral part
3 minutes later, central part 65 degrees, peripheral part 350 degrees or more 2 1 minute later, central part 81 degrees, peripheral part 200 degrees
3 minutes later, central part 100 degrees, peripheral part 350 degrees or more

Experiment 4
Bake two bowls under the same conditions as in Experiment 2.
1 5 minutes and 40 seconds.
5 minutes 40 seconds high fire time is 3 minutes 52 seconds high fire rate 68%
The temperature of the net at the end of 5 minutes and 40 seconds is not less than 300 degrees. FIG. 9 is an image of the eyelid at the end.
2 4 minutes and 30 seconds.
High fire time during 4 minutes and 30 seconds is 2 minutes and 42 seconds.
The temperature of the net at the end of 4 minutes and 30 seconds is 240 degrees. FIG. 10 is an image of the bag at the end.

          What is found from these experiments 3 and 4 is that the flame from the gas stove burner hits almost uniformly from the center to the end of the saucer in the case of the conventional oven used in experiments 1 and 2. The temperature difference between the central part of the net part and the peripheral part is 2 to 60 degrees, and when the temperature of the part where the food is placed is around 250 degrees suitable for baking the food, the temperature at the center of the saucer part also rises. S is activated, and the gas supply is cut off or minimized, resulting in a fire. As a result of the melting fire, the flame does not rise upward from the slit provided in the saucer part, and it is difficult to get burnt. On the other hand, when the gas stove baking apparatus 100 according to the embodiment of the present invention is used, the flame from the gas stove burner is caused to rise until the temperature in the center rises due to the inclination of the flame on the saucer part. By moving outward from the center, the temperature difference of 120 degrees or more is created between the center of the net and the periphery, and the temperature of the portion where the food is placed becomes around 250 degrees within 3 minutes, which is shorter than the conventional product. Ingredients can be baked in heating time. In addition, since the temperature rise in the central part is small relative to the temperature in the peripheral part, the thermal sensor S does not operate, and the ratio of high fire is higher than in the conventional product, and by tilting the saucer part on the outside upper side Since the slit of the saucer part is provided on the direction of the flame to go, the flame is more likely to rise upward, and the food can be burnt and burnt.

          In the above-described embodiment, the inclination angle of the saucer portion is 8 to 8 because the flame and heat of the gas stove burner are efficiently transmitted to the foodstuff and can be used stably when installed in the gas stove of the gas stove. 10 degrees is good.

          Furthermore, in the above-described embodiment, a type in which the intermediate net part 140 in which a punching metal plate is coated with ceramics is provided between the tray part 110 and the net part 130 may be used.

          In the above-described embodiment, the plurality of slits 112 are provided in the bottom surface portion 111 of the tray portion 110. However, the slits 112 may not be formed.

Further, in the above-described embodiment, the tray part 110 is open, but a cover body that covers the entire tray part 110 may be provided. In this case, the cover body may be of a type that is hinged to the tray part 110 so as to be openable and closable, or may be of a type that is separate from the tray part 110 and is detachable. When the cover body is provided with a sight glass made of tempered glass, it is possible to confirm the grilled state of food such as fish.

Further, in the above-described embodiment, the tray part 110 has a rectangular thin dish shape, but may be circular. In this case, the net part 130 is also circular, and it may be of a type that does not have a handle portion and that is used by placing it on the circular saucer part 110.
The inclined portion may have a curved shape.
