Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate-type cooker equipped with a hot plate on the top facing an internal burner.

Conventionally, in this type of cooker, combustion exhaust from the burner is generally exhausted to the outside through an exhaust duct that blocks the burner so that it does not accumulate inside the cooker body, but even with this type of cooker, radiant heat from the burner and The heat from the combustion exhaust flowing into the exhaust duct heats the inside of the cooker to a fairly high temperature, which tends to damage control parts such as gas cocks and electrical equipment housed within the cooker.

The purpose of the present invention is to provide a cooking device that eliminates such inconveniences, and the inside of the cooking device main body 3, which is equipped with a hot plate 2 on the upper surface facing the internal burner 1, is A rear chamber 5 housing an exhaust duct 4 leading to the
and a front chamber 7 which accommodates a gas cock and other control parts 6 are separated by a heat shielding wall 8, and the mixing pipe 1a of the burner 1 is faced into the front chamber 7 through the heat shielding wall 8. , an outside air intake hole 9 is formed in the front chamber 7, and the front and rear chambers are provided with a ventilation gap 13 in the middle of the heat shield wall 8 that communicates with the outside air; A heat shield plate 15 is provided between the heat plate 2 and the hot plate 2 with a gap 14 connected to the ventilation gap 13;
The ventilation gap 14 is communicated with outside air through a ventilation hole 20 provided in the upper part of the side wall of the cooking device main body 3 in front of the front edge of the hot plate 2.

The illustrated cooking device main body 3 includes a pair of left and right burners 11 in a rear chamber 5 separated by a heat shielding wall 8, and a pair of left and right burners 11 extending from each burner 1, 1 to an exhaust pipe 10 on the rear side. Exhaust duct 4,
The front chamber 7 accommodates control parts 6 such as gas cocks, switch devices, and solenoid valves that are operated by a pair of operators 11 and 11 on the front corresponding to each burner 1, 1. The burner 1°1 is fitted and supported by a heat shielding wall 8 at a mixing pipe 1atla extending forward from its lower end, and gas nozzles 12 provided in a front chamber 7 are arranged to face each other.

The ventilation gap 13 allows outside air to be introduced into the ventilation gap 13 from a ventilation hole 16 at the lower end thereof, passes through the gap 14, and passes through the ventilation hole 18 formed in the support bracket 17 at the front end of the heat shield plate 15 and the gap on the outside. The air is discharged to the outside through a vent hole 20 formed in a front panel 19, which is a side wall of the cooking device main body 3.

Next, to explain the operation, according to the combustion operation of each burner 1, the mixing pipe 1 is passed from the outside air intake hole 9 through the inside of the front chamber 7.
A flow of outside air is generated toward the front chamber 7, and the front chamber 7 is cooled, and the heat from the rear chamber 5, which is heated by the burner 1゜1 and the exhaust ducts 4, 4, is also blocked by the heat shield wall 8. Therefore, the temperature rise in the front chamber 7 is prevented as much as possible.

In this case, the outside air flowing into the ventilation gap 13 between the front and rear double heat insulation walls 8 and 8 provides a more effective heat shielding effect, and the outside air flowing from the ventilation gap 13 into the gap 14 allows the hot plate 2 to It is cooled at the front end, and together with the heat shield plate 15 on the upper part of the front chamber 7, the hot plate 2 is cooled.
Heat transfer to is also prevented as much as possible.

Also, by cooling the front end of the hot plate 2, the burner 1
Even if the temperature directly above the front end reaches, for example, about 500°C, the front end is maintained at about 50°C, so even if you accidentally touch the front end when operating the front controller 11, you will not get burned. Moreover, it is possible to cook new food while keeping cooked food by placing cooked food on the front end, which greatly improves usability.

In this way, according to the present invention, the inside of the cooking device main body 3 is divided into front and rear chambers 5 and 7 by the heat shielding wall 8, and the burner 1 in the rear chamber 5 is divided into the front and rear chambers 5, 7.
In addition to preventing the heat from the exhaust duct 4 from reaching the inside of the front chamber 7, the mixing pipe 1a of the burner 1 is made to face the inside of the front chamber 7, and an outside air intake formed in the front chamber 7 is provided. A flow of outside air is caused from the hole 9 toward the mixing tube 1a, and the heat shielding wall 8 is provided in two layers in the front and back with a ventilation gap 13 communicating with the outside air in the middle, and furthermore, the front chamber 7 is A heat shield plate 15 is provided at the top with a gap 14 connected to the upper end of the ventilation gap 13 between it and the hot plate 2, and the ventilation gap 14 is connected to the cooking device body in front of the front edge of the hot plate 2. 3.Communicate with outside air through the ventilation hole 20 provided in the upper part of the wall,
The conduction heat transmitted to the front chamber 7 side via the hot plate 2 and the heat shield wall 8 is cut off by the gap 13.14, and the natural ventilation flowing through the gap 13.14 causes the heat shield wall 8 and the heat shield wall 8 on the front chamber 7 side to The heat from the hot plate 2 can be carried away to the outside, thereby effectively insulating the rear chamber 5 from the heat from the burner 1, and also being cooled by the air cooling effect caused by the flow of outside air toward the mixing tube 1a, resulting in a synergistic effect. In front room 7
This has the effect that the temperature rise inside the front chamber 7 is prevented as much as possible, and the control components 6 housed in the front chamber 7 are not damaged by heat.
