[0001] System for ventilation [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen ventilation system, and more particularly, to a kitchen ventilation system that minimizes air pollution in a kitchen by causing heat, odor, and contaminants generated during a heating operation on a kitchen countertop to flow toward an exhaust hood. ≪ / RTI >

Generally, the kitchen environment, which is hermetically sealed by a pollution source such as heat, smell, pollutants, and harmful substances, which is generated during cooking in a gas stove or an electric cooking stove on a countertop, is rapidly deteriorated, So that the exhaust gas is forcibly exhausted.

A universal kitchen ventilation system includes a cooking stove extending horizontally from a wall surface for cooking food, a gas stove placed on the cooking stove, and an exhaust hood disposed on the cooking stove, When the exhaust hood is operated by using a switch in the course of heating, not only the heat and the smell generated from the inside of the heating container but also fine dust and contaminants around the countertop are discharged using the exhaust hood.

Conventional kitchen ventilation systems use a ventilation hood to expect a good intake of contaminants directly underneath the exhaust hood but inhale contaminants remaining in areas adjacent to the wall or in front of the gas stove Difficulty can result in contaminated air being diffused throughout the kitchen before being vented through the exhaust hood. That is, in the past, only 70% of the pollutants generated during the exhaust hood operation are discharged, while the remaining 30% of the air is increased due to the heat, thereby spreading into the kitchen interior and ceiling.

Accordingly, it is an object of the present invention to provide an air conditioner in which air discharged from an exhaust passage module disposed at the rear of a gas cooking stove forms air curtains on a wall surface side of a kitchen so that contaminants, And to provide a kitchen ventilation system that allows the user to smoothly enter the hood.

According to another aspect of the present invention, there is provided a kitchen ventilation system including a cooking chamber extending from a wall, a cooking stove disposed on the cooking chamber, a hollow exhaust passage module positioned behind the cooking stove on the cooking chamber, And an exhaust hood located above the exhaust flow channel module, wherein the exhaust flow channel module is formed with a nozzle hole passing through the inside and the outside of the exhaust flow channel module, and the nozzle hole may be formed to be inclined upward.

It may be preferable that the diameter of the nozzle hole gradually decreases toward the upper direction.

The exhaust passage module may include a first front portion disposed below the nozzle hole and a second front portion disposed on the upper side of the first front portion with respect to the nozzle hole.

The second front portion may be formed of a curved surface having at least one inflection point.

The second front portion may have a first curved portion convex to the cooking stove side and a second curved portion connected to the first curved portion and recessed toward the cooking stove side.

Preferably, the kitchen ventilation system further includes an air supply module connected to the exhaust air flow module and having an air inlet pipe and a blower fan.

The diameter of the nozzle hole may preferably be in the range of 0.1 mm to 3.0 mm.

The present invention provides a kitchen ventilation system in which air along a curved surface formed in an exhaust passage module disposed at the rear of a gas cooking stove forms an air curtain toward a wall surface of a kitchen, So that it is smoothly drawn into the exhaust hood arranged on the upper side, thereby minimizing the spread of contaminants in the kitchen.

In the present invention, a small amount of air is discharged along a nozzle hole of an exhaust flow channel module to exhaust a pollutant generated directly from the gas stove, and at the same time, air flowing through the upper part of the gas stove Induce circulation. The air curtain formed on the rear wall of the gas stove through the above-described structure prevents contaminants such as grease, which are generated during the cooking process, from being stretched, thereby ensuring a comfortable working space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A kitchen ventilation system 100 according to the present invention will be described with reference to the accompanying drawings. The embodiments described below are provided for illustrative purposes only and do not limit the technical scope of the invention.

The overall configuration description of the kitchen ventilation system 100

The configuration of the kitchen ventilation system 100 according to the present invention will be described with reference to Figs. 1 and 2. Fig.

The kitchen ventilation system 100 includes a cooking stove 30 extending from the wall surface 10, a stove 32 disposed on the cooking stove 30, a hollow exhaust duct 32 located behind the stove 32 on the cooking stove 30, An exhaust hood 20 located above the exhaust flow path module 50 and an air supply module 40 disposed under the countertop 30.

The air supply module 40 includes a case 45 in which an inlet 41 and an outlet 43 are formed, a blowing fan 42 rotatably arranged in the case 45, (Not shown).

The kitchen ventilation system 100 may further include a wireless controller 70 that enables the ventilation fan 42 and the exhaust hood 20 to operate wirelessly. The user can adjust the operation intensity of the blower fan 42 and the exhaust hood 20 by using the wireless controller 70. [

A nozzle hole 57 penetrating the inner and outer surfaces of the exhaust passage module 50 is formed in a front portion of the exhaust passage module 50 facing toward the cooking stove 32. The nozzle hole 57 is formed obliquely upward.

The present invention is advantageous in that the air discharged from the exhaust flow path module 50 moves along the curved surface formed on the nozzle hole 57 and the front surface of the exhaust flow path module 50 by the Bernoulli neatness and the coanda effect, The air curtain C region can be formed adjacent to the wall surface 10 of the kitchen. The area of the air curtain C is an air flowing layer having a predetermined thickness and a source of heat such as heat, odor, and contaminant introduced from the front of the heating vessel 35 and the counter top 30 placed on the cooking stove 32, .

In addition, the area of the air curtain (C) causes air circulation flow from the front of the cooking stove (30) continuously by acting to suck and amplify ambient air of 10 to 30 times by discharging air at a high speed It is possible to create a pleasant kitchen indoor environment.

Explanation of the configuration of the exhaust flow channel module 50

Hereinafter, the exhaust flow path module 50, which is a core component of the kitchen ventilation system 100 of the present invention, will be described with reference to FIG.

The exhaust flow path module 50 includes a first front portion 51 disposed at a predetermined distance from the wall surface 10 in the direction of the stanchion 32 and a second front portion 51 disposed at an upper portion of the first front portion 51 And a top portion 56 connecting the second front portion 55 to the wall surface 10.

The first front portion 51 includes a first inner surface portion 52 and a second inner surface portion 53 connected to the first inner surface portion 52 inwardly. The intersection points of the first inner surface portion 52 and the second inner surface portion 53 protrude relatively to the wall surface 10 side. That is, the inner surface of the first front surface portion 51 is kept away from the wall surface 10 with respect to the protruding portion 54.

The second front portion 55 has a first curved portion 55a convex to the stanchion 32 side and a second curved portion 55b connected to the first curved portion 55a and recessed toward the stanchion 32 side. It can be seen that the inflection point is formed at the portion connecting the first curved portion 55a and the second curved portion 55b when the second front portion 55 is viewed. With this principle, the second front portion 55 can form a plurality of inflection points to form two or more curved portions.

The nozzle hole 57 may be formed between the first front portion 51 and the second front portion 55 so as to be gradually narrowed toward the upper direction. The shape of the nozzle hole 57 will now be described using the Bernoulli theorem of the formula (1), which is a known energy equation.

Bernoulli's theorem states that the energy of the fluid must be preserved and it shows the relationship between velocity and pressure in the process of air flow through the nozzle hole 57. In the present invention, when the influence of the positional variable in the nozzle hole 57 is not large, a phenomenon occurs in which the velocity is low and the pressure is low at a relatively different point when the velocity is low at one point and the pressure is high .

The air ejected from the nozzle hole 57 moves along the second front portion 55, causing a change in the distribution of the pressure. The diameter of the nozzle hole 57 decreases from the inlet 61 toward the outlet 63 so that the air flowing through the inlet 61 of the nozzle hole 57 flows through the outlet 61, (63), the velocity is increased by Bernoulli's theorem. Here, it is preferable that the diameter of the nozzle hole is set in a range of 0.1 mm or more and 3.0 mm or less.

In addition, the air discharged to the outlet portion 63 of the nozzle hole 57 tends to flow at a high speed along the outer surface of the second front portion 55 due to the Coanda effect. That is, the flow (reference numeral 66) from the inside of the exhaust flow path module 50 through the nozzle hole 57 causes the surrounding flow flow 67 approaching from the periphery of the stanchion 32 onto the second front portion 55 To the exhaust hood 20 side.

This change can be made possible by the Coanda effect found by H. Coanda, where fluids ejected horizontally from the surface of the object generally advance rapidly along the surface of the object, And a low pressure distribution is formed in the main body. In other words, if a fluid is ejected through a thin slit such as a capillary, it will appear to bend along the surface if there is a curved wall adjacent to the outflow direction. The Coanda effect can be applied to the present invention as a physical phenomenon that is applied to other fields of industry such as exhaust and ventilation, wire laying, optical fiber laying for communications, and large boiler cleaning.

As described above, in the kitchen ventilation system according to the present invention, a small amount of air is discharged along the nozzle hole of the exhaust channel module to exhaust the pollutant generated directly from the gas stove, and at the same time, the coanda effect and the Bernoulli theorem And induces air circulation in the upper part of the gas stove through the used flow. Through this process, the air curtain is formed on the side of the wall of the kitchen so that contaminants generated during cooking using the gas stove can be smoothly drawn into the exhaust hood disposed on the upper side of the gas stove, thereby minimizing the spread of contaminants in the kitchen It is effective.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
