The present invention relates to a kitchen exhaust hood, and more particularly, it relates to a kitchen exhaust hood, and more particularly, it relates to a kitchen exhaust hood which is capable of quickly discharging smoke or vapor generated during cooking, And a kitchen exhaust hood in which a simple and hygienic cooking environment is realized.

The exhaust hood is installed on the upper part of the cooking device provided in the kitchen, so that the ventilation device is installed to separate the smoke, the smell and the vapor generated in the cooking process outdoors to establish a pleasant cooking environment, It is difficult to collect the vapors completely so that the smell of food spreads into the indoor space or the wall surface is contaminated by the vapor.

No. 10-1306756 discloses a structure in which three long exhaust slots are provided at the bottom of the exhaust hood and an elongated vertical plate is provided below the left and right surfaces of the exhaust hood, To prevent the inflow of outside air into the cooking space by guiding the discharge path to the indoor space and to prevent the inflow of the outside air into the cooking space, thereby providing a range hood in which a fully upward air flow is formed.

However, in the prior art, since the exhaust structure for collecting soot and noxious gas is formed in a slot shape, the reverse flow resistance is increased and the discharge path is not straight, so that secondary resistance is generated in the circulation process of the air, There is a problem that the operation noise of the motor is increased and the circulating air bumps against the inner wall and the operation noise is increased.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method and apparatus for cleaning and maintaining And an object of the present invention is to provide a kitchen exhaust hood in which management is simple and a sanitary cooking environment is realized.

In order to achieve the above object, the present invention is characterized in that a cooking space 11 is formed to extend downward along the periphery of a hood 3 provided with an exhaust duct 1, and an opening 13 is formed at one side And an air inflow part 20 penetrating the outer circumferential surface of the exhaust duct 1 so as to form an inclined angle with the exhaust direction and connected to the air blowing port 21 to introduce outside air, .

At this time, the cover 10 is characterized in that a plurality of ventilation holes 15 are formed along the periphery of the lower end so as to smoothly circulate the air.

The cover (10) is coupled to the hood (3) so as to be openable and closable around the hood (3).

The air inlet 20 is inclined along the tangential direction of the outer circumferential surface of the exhaust duct 1 to form a vortex in the exhaust duct 1.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an exhaust hood for a kitchen, wherein the exhaust hood for the kitchen can be easily used because smoke and vapor generated during cooking are quickly discharged, operation noise is reduced, foreign matter adhesion on the inner side of the structure is reduced, And a cover 10 and an air inlet 20 so that a simple and hygienic cooking environment can be realized.

1 and 2, the cover 10 extends downward along the periphery of the hood 3 provided with the exhaust duct 1 and surrounds the periphery of the cooking utensil (the gas stove in the case of the illustrated embodiment) By forming the isolated cooking space 11, it is possible to prevent the air contaminated by the smoke, the food odor, and the vapor generated in the cooking process from diffusing into the indoor space. Since the cover 10 is used in a state adjacent to flame or heat, it is preferable to use a flame retardant or flame retardant material such as a metal plate or glass, flame-retarded plywood, fabric, film or the like.

At this time, the cover 10 is partly opened to form an opening portion 13 for the operation of the cooking device, the input of the material, and the handling of the finished dish. The opening portion 13 is formed in front of the cooking device The position and the shape of the cooking utensil can be selectively changed according to the size, shape and cooking method of the cooking utensil.

However, the opening 13 is provided with a step 13a for preventing the contaminated air from diffusing into the indoor space. Since the contaminated air is heated to the heating of the cooking process, it is naturally moved to the upper side of the cooking space 11 by the convection phenomenon as shown in FIG. 2, So that the air is exhausted to the outside through the exhaust duct 1 provided in the upper part of the cooking space 11. [

As shown in FIGS. 3 and 4, it is also possible to further include an opening / closing door 14 on the cover 10. The opening and closing door 14 may be variously modified such as a slide, a sliding door, a folding or a curtain, and it is preferable to adopt a transparent material such as a film, a synthetic resin, or glass so that the cooking process can be visually confirmed. As shown in FIG. 4, when the opening / closing door 14 is closed in the cooking process, the outflow of polluted air to the outside of the cooking space 11 is completely blocked, and thus the exhausting efficiency is improved. The additional effect of reducing the heat loss of the cooking process appears.

Meanwhile, the cover 10 is formed with a plurality of ventilation holes 15 along the periphery thereof so as to smoothly circulate air. The air circulation of the cooking space 11 isolated by the cover 10 and the opening and closing door 14 can be freely performed due to the formation of the ventilation hole 15. This prevents the occurrence of soot or thermal power deterioration due to incomplete combustion in the cooking process It is resolved. The ventilation hole 15 is formed at the lower end of the cover 10 so that the inflow air does not disperse the polluted air that is sparking during cooking and reduces the thermal power or is rising toward the exhaust duct 1, But it is also possible to additionally provide a separate control plate 16 which can be opened and closed as in the embodiment shown in FIG. 5 so that the amount of inflow air can be adjusted to the situation.

The cover 10 is openably and closably coupled to the hood 3 so as to be adjustable in position and width. For this, a separate fixing structure such as a rail or a hook is formed around the hood 3 to which the cover 10 is coupled. By changing the position of the cover 10 as shown in FIG. 6, The hood and the exhaust duct can be easily cleaned and repaired. For this purpose, it is preferable that the cover 10 adopts a structure that is easily deformable, such as a foldable structure that can be folded or a divided structure made of a plurality of plate materials.

On the other hand, the air inlet 20 penetrates the outer circumferential surface of the exhaust duct 1 so as to form an inclination angle with the exhaust direction, and the air outlet 21 is connected to force the outside air into the exhaust duct 1. As shown in FIG. 2, the outside air forced by the air blowing port 21 forms an air flow in the spraying direction, sweeps out the polluted air raised by the convection, and discharges the polluted air to the outside. Since the intake and blowing means, such as a fan or a motor, provided in the inside of the exhaust duct 1 are not disposed, oil or foreign substances contained in the polluted air are quickly discharged without being adhered to improve the cleanliness of the inside of the exhaust duct 1 Therefore, it is possible to solve the unhygienic situation in which foreign matter adhered to the cooking cavity 11 is dropped, and the convenience of the cleaning operation is improved.

Since the inflow of the contaminated air is prevented by the jetting pressure of the air blowing port 21 that receives the outside air and supplies the outside air to the inside of the exhaust duct 1, So that the life of the device is prolonged and the necessity of cleaning or maintenance work is reduced, thereby improving convenience of maintenance.

However, since the circulation resistance of the air is reduced due to the simplification of the internal structure of the exhaust duct 1, it is possible to reduce the volume of the air blown by the blower 21, A low output fan with low operation noise is used to solve the problem of operating noise which is a problem of the existing exhaust hood. As shown in the embodiments of FIGS. 1 and 2, the exhaust duct It is possible to selectively adopt the form of being exposed to the outside or inserted in the inside of the exhaust duct 1.

7 shows an embodiment of the air inflow part 20, wherein the air inflow part 20 is formed to be inclined along the tangential direction of the outer circumferential surface of the exhaust duct 1. As the injection direction is inclined, the air injected from the air inlet 20 circulates along the inner surface of the exhaust duct 1 in a spiral shape to form a vortex. Due to the nature of the vortex that sucks the surrounding air, The efficiency of the exhaust hood is further improved and the air drawing the spiral along the inner circumferential surface of the exhaust duct 1 is adhered to the inner circumferential surface of the exhaust duct 1 There is an additional effect of reducing the amount of the product.

8 shows another embodiment of the air inlet 20, wherein a plurality of the air inlet 20 are spaced apart from each other along the circumference of the exhaust duct 1. Each of the air inflow portions 20 can be selectively applied with a linear or vortex type air injection by varying the angle of engagement and air is simultaneously blown from the plurality of air inflow portions 20, So that the intake and exhaust efficiency is improved.

8 (a), each of the air inflow portions 20 may be provided with the air blowing outlets 21 individually. However, in the state of being coupled with the air blowing outlets 21 as shown in FIG. 8 (b) It is also possible to realize a jetting structure in which a plurality of air inflow portions 20 can be simultaneously controlled by one blowing means by using the housing 23 coupled to the periphery of the duct 1.

The hood (3) is provided with an air inlet port (30) in which an air speed increasing path (31) is formed so that the sectional area becomes narrower toward the upper side. The air intake port 30 is formed with a plurality of airflow increasing passages 31 by a partition 33 across the inside of the hood 3 and is provided with a variety of air increasing passages 31, And each of the air speed increasing passages 31 is formed in a shape in which the sectional area becomes narrower toward the upper part so as to increase the flow rate of the air introduced into the air increasing path 31, thereby improving the discharge efficiency of the polluted air. Referring to the respective drawings, the operating state of the exhaust hood provided with the inlet port 30 is as follows. Since the air inside the hood 3 is discharged by the operation of the air outlet 21, the internal pressure is lowered, The air is forcibly introduced into the hood 3 and the flow rate of the air passes through the air speed increasing passage 31 where the cross-sectional area becomes narrower as the inflow of the contaminated air is increased. The internal pressure of the suction port 30 is reduced in proportion to the suction force of the contaminated air, thereby further improving the exhaust efficiency.

As described above, when the exhaust speed is increased in the process of passing through the narrow air increasing passage 31 as described above, the contact time between the surface of the hood 3 and the intake port 30 and the contaminated air is reduced, In particular, in the case of the wind visor as shown in FIG. 10, it is also possible for the user to adjust the flow rate of the air by adjusting the angle of engagement of the partition 33 forming the air speed increasing passage 31 .
