Description

Range hood unit for kitchen with auxiliary intake {APPARATUS FOR RANGEHOOD HAVING SUBSIDIARY INHALE HOLE IN KITCHEN}

The present invention relates to a range hood device for a kitchen, and more particularly, to prevent contaminated air (hereinafter referred to as "polluted air") consisting of water vapor, smoke, odors, and polluted gases generated in the kitchen from spreading in the kitchen. The present invention relates to a range hood apparatus for a kitchen having an auxiliary suction port for collecting polluted air more efficiently.

Generally, in the case of a kitchen, contaminated air, which is composed of steam, smoke, odors, and polluted gases generated when cooking various foods, is severely generated. In particular, in the case of commercial or large kitchens in which a large amount of food is cooked, the amount of contaminated air is increased. Therefore, in order to discharge these contaminated air or heat to the outside of the kitchen, a hood apparatus is generally installed at the top of a heating apparatus or a range, and contaminated air containing heat or food particles generated from a kitchen table through a collecting portion formed in the hood apparatus. Inhaled and discharged to the outside. Generally, the polluted air generated in the kitchen rises in the direction of the kitchen ceiling due to the high temperature, and thus, the hood device is generally installed on the ceiling of the kitchen or the top of the countertop, and the polluted air sucked by the exhaust fan acts as a duct. It is usually discharged to outside.

In general, the range hood device for a kitchen is manufactured and installed in a limited size because the cooking space of the cooker should be secured and the space inside the kitchen is limited. Therefore, when food smell, smoke, heat and polluted air generated during cooking are increased, it is difficult to collect them 100% and discharge them to the outside. In order to increase the collection efficiency to increase the size of the range hood produced and installed, not only the production cost increases but also the cooking space is narrowed there is a problem that the activity of the cooker is generated. Furthermore, if the range hood, which is mainly installed on the ceiling, is enlarged, the kitchen may become dark.

Therefore, the hot contaminated air generated during cooking rises to the ceiling with odors, smoke, and contaminants, and some of them are discharged to the outside by the hood device, but some of them are convection out of the hood's collection range. Will spread to Therefore, there is a need for a highly efficient hood device that collects contaminated air within a range that does not significantly increase the production cost and does not increase the area occupied by the hood.

The present invention is the size of the range hood device, which is limited in size and installation space, the same size as that of the general kitchen range hood device, but has a secondary suction inlet to more efficiently collect the polluted air. That is, it is installed in the upper part of the kitchen in the same way as a general hood device, and is installed in the first exhaust duct and firstly sucks the polluted air through the first suction port opened vertically, and discharges it to the outside, and the front or upper foot of the range hood. A second exhaust duct having a second suction port is further installed in the trap to further collect contaminated air that is not collected at the first suction port and rises.

The surface formed with the inlet port may be manufactured in a line type, louver type, perforated type, etc. according to a selection, and a filter is installed inside each of the first inlet port and the second inlet port so that the air from which contaminant particles are removed is discharged to the outside. can do. In addition, each of the first exhaust duct (first inlet) and the second exhaust duct (second inlet) may be separately operated by connecting a separate exhaust fan, or may be connected together and exhausted by one exhaust fan. When one exhaust fan is used jointly, the intakeable air flow rate of the second intake port has a value ranging from 20 to 50% of the first intake air flow rate. That is, the first suction port serves as the main suction port, and the second suction port serves as the auxiliary suction port.

According to the range hood apparatus for a kitchen according to the present invention, it is possible to improve the collection rate of contaminated air within a limited space range without increasing the size of the range hood. In addition, it is relatively advantageous in terms of cost since it is not necessary to make the hood itself large to improve the collection rate.

In addition, unlike the existing improved range hood, there is no need to install a separate supply and exhaust fan and a supply and exhaust mechanism in order to discharge the contaminated air that is not collected and rise and spread, thus eliminating the factor of cost increase. have.

In the range hood apparatus for a kitchen according to an embodiment of the present invention, the first suction port 11 is provided to effectively remove the contaminated air that rises due to a high temperature because it is positioned above the kitchen counter, and the first suction port ( A second suction port 21 is additionally installed to remove the contaminated air rising out of 11).

The first suction port 11 refers to one end of the first hood duct 10 which is provided inside the range hood device and communicates with the outside, and the second suction port 21 is the second exhaust duct. Mean one end opened to the outside of the (20). The shape of the first and second exhaust ducts 10 and 20 is not limited, and generally a circular duct may be used. The first and second exhaust ducts 10 and 20 serve as passages through which the air sucked from the first and second suction ports 11 and 21 passes through the action of the exhaust fan 30. If necessary, a filter may be installed inside the duct to filter contaminants in contaminated air during exhaust. The negative pressure chamber 13 is provided at a portion where the first exhaust duct 10 and the second exhaust duct 20 meet. Polluted air is sucked through the first exhaust duct 10 and the second exhaust duct 20 in the negative pressure chamber 30 and discharged to the outside.

If necessary, one end of the first inlet 11 may be further provided with a first inlet cover 12 to more efficiently collect contaminated air. The first inlet cover 12 is a funnel shape having a large cross-sectional area in a direction away from the first inlet 11, and contaminated air is collected to the first inlet 11 along the inclined surface of the first inlet cover 12, so that the collection rate is reduced. Can improve. The second inlet 21 may be provided with a cover, but the second inlet 21 has a structure in which the raised air is sucked and exhausted from the side, and thus, unlike the first inlet 11, the cover is provided with the cover. The cover having a certain angle and range allows only a limited range of contaminated air to be sucked in, so that the collection rate may be rather low. Therefore, it is preferable that the second suction port 21 is not provided with a cover for a separate collection.
