Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a range hood for kitchens, and in particular to a range hood for kitchen use, in which tta is artificially generated and fresh outside air and contaminated inside air are simultaneously and automatically activated. This invention relates to a kitchen range hood that uses an artificial tornado mechanism.

BACKGROUND OF THE INVENTION Conventional kitchen range hoods generally use an exhaust fan for exhausting air. Therefore, in an airtight cooking room such as an apartment, air is not supplied and the exhaust efficiency is poor, and since there is only a suction action, the suction is not directional, so the collection efficiency of smoke and steam is poor, and the surrounding Since it sucks in a large amount of air and has a large air volume, it consumes a lot of electricity. In addition, because smoke and steam are once diffused and then sucked in, not only do surrounding walls and suction surfaces get dirty with oil and smoke, but air supply vents must be installed to improve exhaust efficiency. Many problems arose, including the need to open windows, which hindered the effectiveness of heating and cooling.

Problems to be Solved by the Invention Problems to be solved by the present invention lie in attempts to solve the problems caused by conventional methods. In other words, ■ creating an artificial tornado above the gas range in order to increase exhaust efficiency; ■ creating an artificial tornado that simultaneously sucks in fresh outside air and polluted internal air; There are problems that the present invention aims to solve, such as forming an air curtain in the central space of the gas range to generate gas.

Means for Solving the Problems The present invention was developed to solve the above problems, and includes a suction hood equipped with a suction blower that sucks in and blows fresh outside air, and A range hood main body is provided with an exhaust hood equipped with an internal exhaust blower for sucking and discharging inside air, and an air curtain blow-off pipe is provided with an air blow-off hole for blowing out the sucked air. Curtain blow-off pipes are installed on a gas range that faces two corners of the range hood main body and has walls on two sides, forming air curtains that extend in opposite directions from the air blow-off holes of the air curtain blow-off pipes. , and a kitchen range hood that generates an artificial tornado in the free space at the center of the gas stove by the wake action of the air curtain, and collects and discharges exhaust gas, smoke, steam, etc. generated when the gas stove is used. Furthermore, an air curtain blower is attached to the suction blower, and the exhaust blower is operated simultaneously to generate an air curtain and an artificial wind turbine at the same time, thereby eliminating fresh outdoor air and indoor polluted air. All these problems can be solved by providing simultaneous and automatic ventilation. That is, the means for solving the problems of the present invention are as follows:
■In order to generate an artificial tornado in the free space in the center of the gas range, an air curtain is formed between the gas range and the range hood, and the center can be sucked in through an exhaust blower.■Air curtain The air that forms the tornado and the air that is exhausted as an artificial tornado can be operated at the same time. ■ The air that circulates fresh outdoor air and the contaminated air indoors can also be operated at the same time and also serves as a ventilation operation. It's about what I tried to do, etc.

For production The present invention applies the principle of generating an artificial tornado.

First, in the artificial tornado mechanism of the present invention, several air blowing pipes are arranged between shielding plates provided with suction ports, and a circulating flow is created in the air curtain that is continuously formed in the space between the air blowing pipes. (Formation of swirling air?7ri, and this circulation flow (
This is a mechanism that creates an artificial tornado by sucking air from the center of a swirling air current. In other words, the principle of this mechanism is that centrifugal force is applied to the circulating flow (swirling airflow) by air circulation (air curtain), and negative pressure is generated in the center by suction at the center, which causes the air to elongate in the direction of suction. Circulating flow (swirling airflow) in which a core is formed and the centripetal force and centrifugal force on this negative pressure core are balanced
This turns into a vortex (spiral flow), which converges at the center of the circulation flow (& circulation flow) and artificially generates a tornado in the suction direction.

Next, through this artificial tornado generation effect and the generated Qiang Lane,
The function of collecting and discharging contaminated air, etc. generated in a gas range can be performed simultaneously and automatically.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a kitchen range hood using an artificial electric current mechanism according to the present invention, and 1 is the main body of the range hood. A range hood main body 1 is provided with a suction hood 2 having an internal suction blower and an exhaust hood having an internal exhaust blower. The suction blower 3 and the exhaust blower 5 may be those commonly used in the past, but the suction blower 3 can also be used as a blower for forming an air curtain, which will be described later.

Reference numeral 6 denotes an air curtain blowing bar provided with air blowing holes 7, and is attached to the suction blower Ia3.

The air blowing holes 7 are formed by drilling small holes at equal intervals, and may be small holes opened vertically as shown in FIG. 8 is an air curtain formed by air blown out from the air blowing hole 7 of the air curtain blowing pipe. The air curtain 8 is formed between the gas range 9 and the range hood main body 1 by an air curtain blow-off pipe 6 in the opposite direction (in the direction of the arrow) with a phase IL. By forming the air curtain 8 and suction by the exhaust blower 5, an artificial tonne @A can be generated in the free space at the center of the gas range 9. Note that in order to prevent artificial G 8 A from forming in the gas stove IO portion, the air blowing hole 7 of the air curtain blowing pipe is not provided on the side of the gas stove IO. Note that I+ is a cooking table.

FIG. 2 shows the artificial electric current generation mechanism applied to the range hood of the present invention and its principle. When air is sucked into each air curtain blowout pipe by the suction blower Ja3 shown in FIG. is surrounded by an air curtain 8.

Due to the wake action of the air curtain 8, the swirling airflow B (circulation flow) continues into the space below the air suction port.
occurs, and a core portion C is formed within the swirling airflow B (circulation flow) due to air suction [ID suction. That is, when a circulating flow is formed within the air curtain 8, centrifugal force is applied to the air molecules by this circulating flow, while negative pressure is generated in the center of the circulating flow due to suction, but this negative pressure area Due to centrifugal force, it does not reach the periphery, but forms a core portion C along the center of the circulating flow, which extends for an average length. This negative pressure core part C applies centripetal force to the circulating air molecules, and within the range where centrifugal force and centripetal force are balanced, the circulating flow becomes a vortex flow (spiral flow) and converges at the center while heading toward the air suction port. An artificial tornado will occur.

The fluid characteristics of this artificial tornado are that a) the suction is directional (the velocity of the flow toward the suction port does not change even if it moves away from the suction port); accelerated, C negative pressure core part or the center of the circulating flow is formed first and extends averagely toward the suction port;
(d) The balance between centrifugal force and centripetal force allows tornadoes to be formed at any speed from low to high speeds.

Effects of the Invention Since the present invention is configured as described above, it has the following effects.

A. Since the artificial tornado generation mechanism can be used to generate an artificial tornado in the center of the gas stove, smoke, steam, exhaust gas, etc. generated on the gas stove can be collected.

B. By using a range hood that is equipped with a suction blower and an exhaust blower, it is possible to generate an artificial tornado and the collected contaminated air at the same time.

First, since the range hood is equipped with a suction hood and an exhaust hood, fresh outside air can be sucked in to form an air curtain, while contaminated inside air can be exhausted to the outside, making it effective for indoor ventilation. Can also be used together.

By taking advantage of the characteristics of artificial tornadoes, such as increased suction directionality and collection efficiency, 1. For example, it is possible to achieve a high-performance exhaust effect with a small amount of wind (1 ton).

From the above-mentioned specific effects, the present invention has advantages in terms of production,
It is possible to provide a kitchen range hood that is practical from all aspects such as handling, equipment, and economy.
