Abstract

PURPOSE:To prevent dangerous condition such as carbonization or ignition of surrounding units caused by heat from a gas discharging cylinder under utilization of a simple structure by a method wherein the discharged gas from a self- cooling fan is applied for shielding heat against the discharging cylinders for oven and grill. CONSTITUTION:A heater device 13 is provided with a grill 14 storing an item to be heated and heating the same, an oven 15, a combustion chamber 17 having a burner 16 therein, a fan 18 for supplying heat of the combustion chamber 17 to the oven 15, a motor 19 for driving the fan 18, a self cooling fan 20 for cooling the motor 19, a discharging cylinder 21 for the self-cooling fan 20, and the gas discharging cylinders 22 for the grill 14 and oven 15. With this arrangement, the discharging heat at the oven and grill is shielded by the gas flow from the discharging cylinder of the self-cooling fan. Thus, the heat may not be reached to the system kitchen. Therefore, the danger of carbonization or ignition of the surrounding units caused by the heat from the gas discharging cylinder is eliminated and a safe operation can be assured.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating device incorporated into a so-called system kitchen consisting of a sink, shelves, etc.

The structure of a conventional example and its problems The conventional heating device will be explained below with reference to the drawings. The system kitchen (
(not shown). 6 is a top plate that forms part of the system kitchen, and 7 is an opening into which a stove is installed. Exhaust gas from the grill section 2 and oven section-3 is exhausted from an exhaust pipe 8 and an exhaust pipe 9. 10 is a fan that supplies hot air from the combustion chamber 5 to the open portion 3; 11 is a motor that drives the fan 10; and 12 is a fan that cools the motor 11.

The operation of the above configuration will be explained below.

Since the exhaust air from the grill section 2 and the open section 3 is extremely hot, the exhaust pipes 8 and 9 become hot, and the rear top plate 6 also becomes hot and carbonizes, posing the risk of ignition. .

Therefore, the temperature of the exhaust pipe 9 is lowered by supplying exhaust gas, which is not too hot, after cooling the motor 11 sucked in by the fan 12 to the exhaust pipe 9.

However, even with this configuration, the temperature was not lowered sufficiently, and the top plate 6 at the rear of the system kitchen was still overheated.

Next, another configuration will be explained using FIG. 2.

Hereinafter, the same members VC will be given the same numbers. In FIG. 2, a heat shield plate 1o is provided between the exhaust pipe 9 and the top plate 6 on the rear side of the system kitchen. A gap 12 is provided between the heat shield plate 10, the outer plate 11 of the heating device 1, and the exhaust pipe 9 as a passage through which heated gas rises in order to improve the heat shield effect.

According to this configuration, the heat of the exhaust pipe 9 is transferred between the heat shield plate 1o and the air gap 12.
The heat shielding effect was achieved to some extent due to the rising airflow. However, several heat shield plates 1Q are required, and heat shield plates 1
0, the exhaust pipe section on the top surface of the heating device 1 becomes very large, and the heat shield plate 1
This also increases costs, such as requiring o.

OBJECTS OF THE INVENTION In view of the above-mentioned conventional drawbacks, the present invention provides a space-saving, cost-saving heating control device having an exhaust pipe with sufficient heat insulation.

Structure of the Invention In order to achieve the object B, the present invention is composed of a grill part, an exhaust pipe of an open part, and an exhaust pipe of a self-cooling fan of a motor for supplying hot air to the open part.

With this configuration, the heat from the exhaust air from the open and grill areas is blocked by the airflow from the exhaust stack of the self-cooling fan, preventing it from reaching the system kitchen, making it safer.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 3, the heating device 13 includes a grill section 14 for storing and heating an object to be heated, an open section 15, a combustion chamber 17 provided with a burner 16, and a fan 18 for supplying heat from the combustion chamber 17 to the open section 16. , a motor 19 that drives the fan 18
, a natural cooling fan 20 that cools the motor 19, an exhaust pipe 21 of the natural cooling fan 2o, a grill section 14, and an open section 15.
It has an exhaust pipe 22. 23 is the front part of the top plate of the system kitchen consisting of a sink, shelves, etc., and 24 is the rear part of the top board of the system kitchen.

According to the above configuration, the area around the exhaust pipe 220 from which the exhaust gas of the grill part 14 and the open part 15 comes out becomes very high temperature, but the exhaust pipe is blocked by the rising air which is not hot because it only cools the motor 19 of the exhaust pipe 21. 22 will not reach the rear part 24 of the top plate of the system kitchen. Further, since the upward air current in the exhaust pipe 21 is forced to flow by the fan 2o, the exhaust pipe 21 does not require a space unlike a conventional heat shield plate.

Effects of the Invention As described above, according to the present invention, by using the exhaust air from the self-cooling fan to insulate heat from the exhaust stack in the open or grill area, carbonization and ignition of peripheral equipment due to heat from the exhaust stack can be prevented with a simple configuration. can eliminate the risk of
