The present invention relates to an exhaust hood, and more particularly, it is possible to continuously provide the supply of oxygen that may be insufficient in the room due to combustion in the countertop through the outer duct, and to provide the combustion air necessary for the countertop in the duct and the outside. The present invention relates to an exhaust hood that can freely adjust the temperature of a room according to a season by replacing it with indoor air or outdoor air through a duct.

In general, cooking (調理) refers to the technique of trimming, slicing and preparing foods to cook foods or to soak and season them in order to make food ingredients good and delicious.

In addition, cooking is intended to cook foods that are difficult to digest, add flavors to other foods as main ingredients, and provide useful nutrients to the human body.

Among the recipes, there are various ways to cook, such as boiling, roasting, baking, boiling, frying, holding, cooking, and steaming.

There are five types of cooking methods that can be heated: fire, water, wood, gold, and earth. The fire is roasted by direct fire. Baking fish or baking potatoes belong to this category, and water is a steaming recipe that uses steam to heat it. In addition, wood (Wood) is a method of heating through wood (木質) is steamed through the wood through the poor conductor of heat, steaming and steaming has a unique taste. Gold refers to a cooking method made by using a metal pot such as iron, copper, and aluminum, such as boiling, frying, and ups and downs. Finally, earthenware is a cooking method using a roasting pan, a giblets, and stones.

Such various cooking methods include a countertop in which heating means, such as an electric heater or a gas stove, is disposed to boil, stir, bake, boil, fry, support, and steam food by applying high temperature heat to food.

At this time, the cooked products inevitably cause an odor due to the high temperature of the heating means placed on the countertop. The smell is SMELL as the food is cooked and the dispersed fine particles float in the air and touch the sense of smell of the person. It is a sensory feeling caused by stimulating cells, and this smell is especially acute when cooking Cheonggukjang (인 國 醬), which is a type of traditionally boiled miso.

And, when cooking fish or meat or boiling a favorite food such as coffee, a kind of broad-concept cooking, the intensity of the smell becomes even worse.

In this way, the smells generated from the heating of the cooked foods are mostly disgusting or unpleasant odors, and perform a bad function causing disgust. In particular, the smells generated in an enclosed kitchen not only cause intensive psychological and mental effects on the worker, Severe physiological effects can cause abnormalities in breathing rhythms, coughing, increased blood pressure due to irritating odors, loss of appetite and nausea and vomiting due to lower digestive and water intake, and olfactory deterioration due to changes in hormone secretion. have.

Odor can also have adverse effects on mental health, such as insomnia, facial disturbances, anxiety, malaise, hysteria, and may involve vomiting and headaches.

Therefore, the present applicant is to propose an exhaust hood that can more easily discharge all the odor generated in the process of heating the workpiece using the flow of air.

The present invention has been made through the proposal as described above, the purpose is to replace the combustion air required in the countertop as indoor air or outdoor air through the inner duct and the outer duct according to the season temperature It is possible to freely control and provide an exhaust hood that can continuously provide the supply of oxygen that can be insufficient in the room due to the combustion of the countertop through the outer duct.

The present invention for achieving the above object,

It is installed in the upper part of the countertop for cooking food and has a built-in exhaust fan for discharging the indoor polluted air to the outside through the hood filter and the duct is installed along the inner surface of the main body having a downward discharge hole In the exhaust hood comprising an intake fan,

The intake fan is installed on the upper part of the main body and communicates with the inner duct for receiving indoor air and the outer duct for receiving outdoor air as its basic features in technical construction.

Hereinafter, a preferred embodiment of the exhaust hood according to the present invention will be described with reference to the drawings. There may be a plurality of embodiments of the present invention, and through this embodiment, the objects, features, and advantages of the present invention can be better understood.

1 and 2 are schematic cross-sectional views of the kitchen provided with the countertop 40 as a schematic view illustrating the flow of air to explain the exhaust hood 100 according to the present invention.

For example, FIG. 1 is not applied to the present invention. The main body 13 having an exhaust fan 12 for discharging indoor contaminated air to the outside via the hood filter 11 is disposed on the countertop 40. Is represented.

Typically, when the exhaust fan 12 is rotated while cooking food, air containing odor particulates coming from the countertop 40 is partially leaked out through the hood filter 11 as shown by the dotted arrows in FIG. 1. Exit, the other part is to turn away from the main body 13 to the flow of indoor air and to stay as it is or to exit through the exhaust fan 12 again.

Before the exhaust fan 12 is operated, the flow of air may be changed at any time according to the movement of an object existing in the room, and when the window or the front door is opened, it may be determined according to the flow of air from the outside.

On the other hand, when the exhaust fan 12 is driven, a discharge force is applied to draw the surrounding air based on the hood filter 11 and discharge it to the outside, so that most of the indoor air passes through the hood filter 11 of the main body 13. The flow trajectory flowing into the center is implemented.

However, as shown in FIG. 1, the flow of air introduced into the hood filter 11 by the driving of the exhaust fan 12 is very limited, thereby discharging all of the indoor air containing odor fine particles coming from the countertop 40. It is pointed out that the efficiency of ventilation is not very satisfactory because some polluted air has to stay indoors like the flow direction of the arrow like a solid line.

That is, the air containing the odor fine particles coming from the countertop 40 is spread out in accordance with the flow of air to the front and forth, while the discharge force discharged through the hood filter 11 by the driving of the exhaust fan 12 is extremely limited. Then there was a problem that can not accommodate all the contaminated air.

In order to overcome this phenomenon, the exhaust hood 100, which was filed by the applicant on May 09, 2000, and received the decision of maintaining technology evaluation on April 06, 2001, has an upper part of the countertop 40 when ventilation is required. The exhaust hood 100 has been proposed to be widened in the horizontal direction and to improve its size when not in use.

3 is a perspective view showing an exhaust hood 100 according to the present invention, Figure 4 is a side view showing an exhaust hood 100 according to the present invention, Figure 5 is a plan view showing an exhaust hood 100 according to the present invention. .

3 to 5, the exhaust hood 100 according to the present invention is installed in the upper portion of the countertop 40 for cooking food to discharge the indoor air polluted through the hood filter 11 to the outside It is based on the main body 13 having an exhaust fan 12 to be made.

Inside the main body 13, a hood filter 11 is installed in an approximately 135 ° direction inclined with the moving direction of the contaminated air having odor particulates coming from the countertop 40 while communicating with the exhaust fan 12. .

The reason why the hood filter 11 is installed to be inclined with the moving direction of the contaminated air rising from the countertop 40 is that indoor counterparts are installed horizontally rather than horizontally in consideration of the position of the countertop 40 being installed close to the wall of the building. In order to more easily discharge the smell of food.

For example, when the hood filter 11 is installed horizontally, the result is that the hood filter 11 is disposed vertically in the wall and the corner space of the building, and thus does not act widely on the odor particulates that can spread out from the countertop 40.

On the other hand, when the hood filter 11 forms a predetermined inclination (preferably 135 °), the hood filter 11 may not only act on the whole odor microparticles spreading out from the countertop 40 but also in combination with the movable plate 22 to form the hopper as a whole. Since it can be implemented can be greatly improved the ventilation efficiency of the indoor air.

The movable plate 22 is coupled to the hinge 21 on the front upper portion of the main body 13 as shown in the side view showing the on-off time of the exhaust hood 100 shown in FIG. 6 and the driving means 30. If it is spread by the hinge 21 is rotated about the hinge 21 is symmetrically spread from the hood filter 11 to realize the hopper shape as a whole, and in the case of being narrowed by the drive means 30 inverted about the hinge 21 As it is rotated, it is concealed into the main body 13 to implement a very simple structure.

At this time, the drive means 30 is started to discharge the odor fine particles generated when cooking food to the outside, the movable plate 22 is unfolded, and the structure implemented in the hopper shape with the hood filter 11 is a countertop 40 It is realized by the action of collecting the contaminated air spreading all the way from the front and back more broadly, and conversely, when the movable plate 22 is closed, it is concealed into the main body 13 so that its size can be minimized as a whole. Not only is simplified, but it also shows the benefits of utilizing the interior space such as kitchen more widely.

In addition, the exhaust hood 100 according to the present invention further includes an intake fan 23 that sucks air in the room above the front of the main body 13, and the intake fan 23 is along the inner surface of the movable plate 22. The installed duct 24 communicates.

In addition, in the exhaust hood 100 according to the present invention, when the indoor polluted air is discharged by the rotation of the exhaust fan 12, the indoor air introduced through the intake fan 23 and the duct 24 is provided with the countertop 40. The nozzle 25 which determines the trajectory of the air to be accelerated and joined together with the contaminated air coming from the) and discharged toward the hood filter 11 is installed in communication with the lower end of the duct 24.

It is preferable that the nozzle 25 maintains a predetermined angle (preferably an angle of 45 °) toward the hood filter 11, and in view of the fact that the hood filter 11 is installed at an inclination angle of 135 °. Indoor air injected through the (25) realizes a structure that can be passed through the hood filter 11 in a straight line to improve the discharge efficiency of the polluted air.

On the other hand, even if the movable plate 22 is unfolded by the driving means 30 to implement the hopper shape together with the hood filter 11, the odor particulates spreading out from the countertop 40 in all directions may not be partially discharged. In this case, as shown in FIG. 2, the air flows by the intake fan 23 which re-intakes indoor or outdoor air and then merges and accelerates and discharges the air together with the contaminated air through the nozzle 25. By forming the track separately, the odor fine particles can be almost completely discharged to the outside by the intake fan 23 and the exhaust fan 12.

At this time, the intake fan 23 directly sucks the remaining air in the room, and is installed to be discharged to the outside via the hood filter 11 and the exhaust fan 12 to improve the ventilation efficiency of the room as well as the same temperature in the room. By directly controlling the flow of air having a temperature that can overcome the condensation that may occur inside the duct 24 by the temperature difference has the advantage of preventing corrosion or electrical adverse effects due to moisture and water droplets in advance. .

7 is a bottom view of the exhaust hood 100 according to the present invention.

Exhaust hood 100 according to the present invention is installed on the upper portion of the worktop 40 for cooking food body having a built-in exhaust fan 12 for discharging the contaminated air to the outside through the hood filter 11 ( 13 is provided along the inner surface of the intake fan 23 to communicate with the duct 24 having a downward discharge hole 26 as shown in FIG.

At this time, the intake fan 23 is installed in the upper portion of the main body 13 is in communication with the inner duct 51 for receiving the indoor air and the outer duct 52 for receiving the outdoor air.

The indoor air or outdoor air provided via the inner duct 51 and the outer duct 52 is sucked by the suction force of the intake fan 23, and then injected into the discharge hole 26 through the duct 24 to produce a countertop. The core of the present invention is that it can provide the combustion air required in 40).

In one preferred embodiment, when the amount of air required for combustion in the countertop 40 in one winter season is provided only with indoor air, circulation of the air in the room itself is prioritized to obtain an additional advantage of improving the room temperature. On the other hand, when the amount of air required to burn in the countertop 40 in the summer only by the outdoor air can be preferable because it can suppress the rise of the indoor temperature by the fresh air of the outdoor.

Of course, the amount of air introduced by the intake fan 23 from the indoor and outdoor can be adjusted by the adjusting member 60 provided between the inner duct 51 and the outer duct 52, and the adjusting member 60 is a rotation shaft 61 provided between the inner duct 51 and the outer duct 52 as an embodiment, and the inner duct 51 and the outer duct 52 with the rotation shaft 61 as the center axis. It includes a control plate 62 that can adjust the amount of air indoors or outdoors while rotating in the direction.

More specifically, when the throttle plate 62 is in close contact with the inner duct 51 with the pivot shaft 61 as the center axis, the inner duct 51 is closed and the outer duct 52 is opened so that the outdoor air When only the inflow, the control plate 62 is in close contact with the outer duct 52, the outer duct 52 is closed and the inner duct 51 is opened so that only indoor air can be introduced. In addition, the inflow rate of the outdoor air or indoor air may be adjusted according to the position of the control plate 62 between the inner duct 51 or the outer duct 52.

In addition, the adjustment member 60 further includes a rotation motor 63 connected to the rotation shaft 61 to rotate forward and reverse, and a control switch for controlling forward rotation and reverse rotation of the rotation motor 63. Further provided with (64) to be able to adjust the control panel 62 manually or automatically to increase the ease of use.

On the other hand, the drive means 30 for moving the movable plate 22 is generally capable of button or remote control, and this drive means 30 is realized by forward and reverse rotation of the motor 31.

For example, the drive means 30 is provided in the transverse direction at the front lower portion of the main body 13, the gear 32 is rotated forward or reverse by the motor 31, and the circular arc on the side of the movable plate 22 It can be realized by interlocking of the toothed rail 33 is formed in the shape to be engaged with the gear 32, it can be employed in various ways, such as belt type or rope type.

That is, when the user turns on the driving means 30 to ventilate the indoor air, the movable plate 22 is unfolded in the horizontal direction while the motor 31 rotates forward and pushes the toothed rail 33 engaged with the gear 32. On the countertop 40, a wide hopper shape is disposed, while when the user turns off the driving means 30, the motor 31 is rotated in reverse to draw the toothed rail 33 engaged with the gear 32. ) Can be concealed into the body 13 to minimize its size.

As described above, according to the exhaust hood 100 according to the present invention, the combustion air required by the countertop 40 may be utilized as indoor air or outdoor air through the inner duct 51 and the outer duct 52 according to the season. There is an advantage that can freely control the temperature of the room.

That is, in the case of providing the necessary amount of air to be burned in the countertop 40 in the winter only with indoor air, the circulation of the air in the room itself is prioritized, and thus, an additional advantage of improving the room temperature may be obtained. In the case where the necessary air amount to be burned by the countertop 40 is provided only by the outdoor air, there is an advantage of suppressing the increase in the indoor temperature caused by the fresh air in the outdoor.
