Abstract

PURPOSE:To enhance heating effect due to convection by a method wherein natural air feeding is effected by utilizing draft for an exhaust gas hood. CONSTITUTION:High-temperature exhaust gas, discharged out of an infrared burner 5, flows verticaly upward due to the buoyancy thereof along an exhaust gas guide 6 extending upwardly from the back side of the infrared burner, thereafter, flows from an exhaust port 7 along the lower surface of the exhaust gas guide 8 extending downwardly at the dack side of the exhaust port 7 and is discharged from the exhaust port 7. In above-described constitution, low-temperature air at the back side of the main body of the gas stove is fed by the draft of the exhaust gas and the viscosity of the air through an opening 9 provided between the exhaust gas guides 6, 8 is mixed with the exhaust gas and the ex- haust gas temperature is decreased. According to the temperature decrease, the circulation of the air in a room is promoted, hot air is not easy to stagnate at the upper layer of a living space and the room heating due to the convection may be effected effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an exhaust hood used in a gas stove, and is intended to more effectively provide a heating effect by convection.

Structure of a conventional example and its problems The exhaust hood 1 of a conventional gas stove leads the exhaust gas from the burner 2 directly to the exhaust, as shown in FIG. Therefore, the temperature of the exhaust gas is much higher than the indoor temperature, and the temperature of the exhaust gas from the appliance 3 is as shown in Figure 2. i
Due to the effect of the heat, the heating of the indoor space is not effective in terms of energy consumption, resulting in energy loss.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and aims to more efficiently perform heating by convection in a gas stove.

Structure of the Invention In order to achieve this object, the present invention provides an exhaust guide device RL that includes an air supply device that naturally supplies air to an exhaust hood using a draft.

With this configuration, the exhaust gas drained from the gas stove mixes with the surrounding air on the way to the exhaust hood, lowers its temperature, and prevents it from accumulating in the double layer of the room due to buoyancy.

This has the effect of heating people's living spaces more effectively.

Description of Embodiments 1 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 3 shows a gas stove according to an embodiment of the present invention,
FIG. 4 shows an example of the configuration of the exhaust guide device.

The high lli+'t exhaust gas discharged from the infrared burner 5 flows vertically upward due to buoyancy, flows along the exhaust guide 6 that extends upward from the rear of the infrared burner, and then flows downward from the exhaust lower to the rear. It flows along the −F plane of the guide 8 and is discharged from the exhaust lower. The exhaust guide device is
The exhaust guides 8 connected to the exhaust lower are on the upper side, and the exhaust guides 6 near the infrared burner 5 are on the lower side, so that they are overlapped with a gap.

In the above configuration, low-temperature air is supplied from the rear surface of the gas stove body through the opening 9 provided between the exhaust guide 6 and the exhaust guide 8 due to the draft of v1 air and the viscosity of the air, mixes with the exhaust gas, and exhausts the air. It has the effect of lowering the temperature.

Effects of the Invention As described above, the following effects can be obtained by using the exhaust guide device according to No. 11-1.

(1) During exhaust, low-temperature indoor air is supplied from the rear and sides using buoyancy and viscous force, mixes with high-temperature exhaust gas, and lowers the exhaust temperature, promoting indoor air circulation and reducing It prevents hot air from escaping into the two layers of the living space, and provides effective heating through convection, resulting in energy savings.

+21 It has the effect of increasing 411 degrees of qi,
The temperature of the appliance around the exhaust port also decreases, reducing the possibility of burns caused by the appliance or ignition even if flammable materials are near the appliance, thereby improving safety.

(3) Since no extra space is required to lower the exhaust gas temperature, the device can be made smaller, resulting in a space-saving effect.
