JPS6391442A - Ventilating method for smoke, etc. generated from gas range - Google Patents

Abstract

PURPOSE:To prevent the diffusion of smoke and hot air, etc. generated from a gas range and remove the change in room temp. caused by the effect of ventilation by forming an air curtain in such a manner that outdoor air is sucked up and then is discharged around the gas range. CONSTITUTION:An air curtain is formed around a gas range 5 by discharging outside air from the air outlet 2a at the peripheral edge part of a hood type ventilator A installed at the upper part of the range 5. This air curtain encloses the smoke and hot air, etc. generated from the range 5 to prevent their diffusion and induce them into the ventilator A. As the air quantity sucked by a fan motor 3 of the ventilator A is larger than that discharged into the air curtain, the smoke and hot air, etc. are not diffused in a room. As the air in the room is scarcely exhausted outside the room, room temp. in a kitchen, etc. is not hardly affected by ventilation. Therefore, as the efficiency of space cooling and heating in summer and winter is satisfactory, the expense for space cooling and heating can be greatly reduced.

Description

[Detailed description of the invention] The non-emission January sucks in outdoor air and blows it out around the gas range to form an air curtain to prevent smoke, hot air, etc. generated from the gas range from spreading. This paper relates to a method for ventilating smoke, etc. generated from a gas range, where the indoor temperature does not change due to ventilation.

Conventionally, as a method for ventilating smoke and the like generated from a gas range, there is generally a method of using a ventilation fan or the like to exhaust smoke, hot air, etc. together with indoor air. When ventilation is performed using these methods, smoke and hot air tend to spread throughout the room.Especially in winter and summer, when the room is being heated or cooled, ventilation can also dissipate hot and cold air along with smoke. This will disturb the effectiveness of heating and cooling systems. For this reason, you have to adjust the air conditioning even more strongly, which increases air conditioning costs considerably.Also, if you use this type of ventilation fan for a long period of time, the smoke and odors will spread, staining the ceiling and lighting equipment, and the smell will also come into the room. There was a drawback that it was difficult to hygienically manage rooms such as kitchens with stains.The present invention is intended to eliminate this in view of the above drawbacks.
In other words, an air curtain is formed by drawing in outside air and blowing it out around the gas range.The air curtain surrounds smoke, hot air, etc. generated from the gas range, prevents them from dispersing, and eliminates indoor dirt. To provide a method for ventilating smoke, etc. generated from a gas range, which reduces the amount of smoke generated from a gas range, does not affect indoor temperature by ventilation, saves energy, and greatly reduces heating and cooling costs.

Embodiments of the present invention will be described below based on the drawings. (A)
is a hood-type ventilation device installed above the gas range (5), and this ventilation device! i (A) includes at least a frame (L) made of a plate material approximately formed on the casing, a hood body (2) that is slidably attached to the inside of the frame (1), and an exhaust fan motor (3). ) and a suction fan motor (4). The hood body (2) has an air outlet (2a) with a large number of holes in its peripheral edge, and an air curtain is formed by blowing out the outside air from the lower floor from the air outlet (2a). Ru. Further, the inside of the frame (1) and the back surface of the hood body (2) are sealed to form a ventilation path, and an inlet (2b) is provided on the outdoor side of the hood body (2).

Furthermore, the suction plowing force of the exhaust fan motor (3) is set to be greater than the capacity of the fan motor (4) for sucking in outside air. is discharged. (6) is the cooking table and (7) is the wall.

In this way, the ventilation method of the present invention blows out outside air from the peripheral air outlet (2a) of the hood type ventilation device (A) installed above the gas range (5), so that the air curtain can 5) Formed around. This air curtain surrounds smoke, hot air, etc. generated from the gas range (5), prevents their diffusion, and introduces them into the ventilation system (A). Moreover, the amount of air blown out inside the air curtain is sucked by the fan motor (3) of ventilation [1 (A)] and discharged outside, so smoke and hot air are not diffused into the room, and the indoor air is almost Since it is not discharged outdoors,
Ventilation has almost no effect on the indoor temperature in the kitchen, etc. Therefore, the efficiency of air conditioning and heating in winter and summer is good, so air conditioning costs can be significantly reduced, and in addition, ceilings and ceilings caused by smoke and odors, which have been problems in the past, have been reduced. A room such as a kitchen can be kept extremely clean without worrying about stains on lighting equipment or bad odors.

Claims (1)

[Claims] A hood type ventilation device (A) is provided above the gas range (5), and outside air is blown out from the peripheral air outlet (2a) of the ventilation device (A) to create an air curtain. The air curtain surrounds the smoke, hot air, etc. generated from the gas range (5), and the air within this air curtain is sucked in by the ventilation device (A) in an amount equal to or greater than the amount of air blown out, and is discharged to the outside. How to ventilate smoke, etc. generated from a gas range.
