Description

A kitchen hood capable of removing grease and sterilizing polluted smoke generated in the kitchen.

The present invention relates to a kitchen hood, and more particularly, to a kitchen hood capable of discharging purified air by inhaling odors, steam and smoke generated when food is cooked to remove grease, odors and microorganisms.

When cooking food using a gas stove for cooking appliances at a general home or restaurant, when frying or meat is heated, steam or smoke containing oil is generated from the food, which causes the smell of oil around the heating appliance and in the house. and the smell of food remains.

In particular, since a relatively large amount of smoke and odors are generated in specialized restaurants such as fast food and restaurants, a range hood for sucking and discharging odors and smoke is installed above the heating device.

However, if only odors and smoke are inhaled and discharged to the outside as they are, the surrounding air may be polluted with smoke containing a large number of microorganisms and grease, and may cause discomfort to neighbors. Although there is no regulation related to this in Korea yet, most Western countries are already regulating the sterilization and purification of smoke generated in restaurants in terms of environmental preservation.

[Figure 1]

[Figure 1] is a picture of the exhaust duct of a fast food restaurant. If the smoke generated from the food is discharged without sterilization, as in [Fig. In this case, grease or pollutants may fall into the restaurant, and the polluted air is discharged as it is, which adversely affects the environment outside the building.

Accordingly, in recent years, a hood capable of purifying and discharging smoke generated during cooking has been developed. However, the conventional sterilization hood has a problem in that air purification is not performed effectively or even if its function is initially expressed, oil stains are deposited in the hood, so that it must be cleaned or replaced periodically.

Recently, a hood that sterilizes microorganisms in smoke generated during smoke cooking has been known, but apart from that it is suitable for home use, when a large number of oil molecules are contained in smoke, such as in a specialty restaurant, it cannot be decomposed, so air purification is effective. could not be done In other words, since the prior art does not effectively remove the oil molecules in the smoke, the finally exhausted air was not completely purified, and oil stains as shown in [Figure 1] are attached to the devices for sterilization, so management is still difficult. existed.

Hereinafter, the present invention will be described in detail with reference to the contents described in the accompanying drawings. However, the present invention is not limited or limited by the exemplary embodiments. The same reference numerals provided in the respective drawings indicate members that perform substantially the same functions.

Objects and effects of the present invention can be naturally understood or made clearer by the following description, and the objects and effects of the present invention are not limited only by the following description. In addition, in describing the present invention, when it is determined that a detailed description of a known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

1 shows a perspective view of a kitchen hood 1 according to an embodiment of the present invention. 2 shows a cross-sectional view of the kitchen hood 1 according to the embodiment of the present invention. 1 and 2 , a kitchen hood 1 according to an embodiment of the present invention includes an exhaust port 3 , an intake port 20 , a primary sterilization unit 30: 301, 303, and a secondary sterilization unit 50 : 501 , 503 ), the injection hole 70 , and the drain hole 90 may be included.

The inlet 20 is provided at the lower portion of the hood 1 and may collect the contaminated smoke 5 and introduce it to the inside. The kitchen hood 1 according to the present embodiment uses water 7 that circulates up and down and does not have a separate fan, so the smoke 5 should be able to be purified while naturally moving from the bottom to the top. Therefore, it is preferable that the inlet 20 is disposed in the lower front of the hood 1 , and thus the smoke collected is introduced into the lower portion of the hood 1 without a separate fan.

The primary sterilization unit 30 branches the cavity inside the hood 1 with an inclined partition wall, and polluted smoke introduced from the suction port 20 as the water sprayed from the injection port 70 circulates up and down in the branched cavity. (5) oil can be removed.

The primary sterilization unit 30 may include a first partition wall 301 and a second partition wall 303 .

In the first partition wall 301, the lower part 3011 forms the ceiling of the intake port 20, and the upper part 3013 is bent in the inner cavity of the hood 1 to form a cavity A having a “∩” shape in longitudinal section. .

In the present embodiment, a light transmitting window 3015 may be installed on the body of the first partition wall 301 . The light transmitting window 3015 is provided with a transparent glass material that can visually confirm the circulation of the internal water 5 . It is preferable that the hood 1 is manufactured so that an external operator can check whether the internal sterilization device is operating properly. Accordingly, the operator can directly check the circulation of the water 7 swirling in the cavity A through the light-transmitting window 3015, and the case where a problem occurs in the water fountain 70 can also be immediately confirmed, so that the purification ability is secured. It is possible to use the hood (1) in

The second partition wall 303 protrudes in a gradient in the direction of the bent upper part 3013 of the first partition wall 301 to guide the water 7 sprayed from the injection hole 70 into the cavity A of the first partition wall 301 . can do. The second partition wall 303 has a predetermined angle upward and protrudes inside the hood 1 . The cavity inside the hood 1 is divided into an A area and a B area by the first partition wall 301 and the second partition wall 303 . The second partition wall 303 forms a predetermined interval with the upper portion 3013 of the first partition wall 301 .

The second partition wall 303 guides the water 7 to the A cavity at an angle formed, and since the induced water is convected by the first partition wall 301 and drained to the lower part of the hood 1, there is a short circuit in the B cavity. A lamp 501 for sterilization may be provided without concern.

The primary sterilization unit 30 can effectively remove oil molecules in the contaminated smoke 5 . Since the primary sterilization unit 30 uses water 7 , oil molecules in the smoke 5 are mixed and washed away together with the water 7 . In this case, the microorganisms in the smoke 5 that are dissolved in water are also primarily filtered, so that the purification ability of the secondary sterilization unit 50 can be sufficiently secured thereafter.

The secondary sterilization unit 50 may remove microorganisms in the contaminated smoke that has passed through the primary sterilization unit 30 by irradiating light with an ultraviolet wavelength. In the secondary sterilization unit 50, the contaminated smoke 5 passing through the primary sterilization unit 30 is introduced into the space opened between the first bulkhead 301 and the second bulkhead 303, so that secondary sterilization will be performed.

The secondary sterilization unit 50 may include a UV-C lamp 501 and a sliding means 503 .

The UV-C lamp 501 generates ultraviolet light and ozone to effectively sterilize microorganisms in smoke. When the sliding means 503 is not provided in the secondary sterilization unit 50 , the UV-C lamp 501 may be disposed on the second partition wall 303 .

Ultraviolet light is a band of light that exists between a wavelength of 1000 to 4000 Å (angstrom) and can be broadly classified into three areas. 1) Ultraviolet rays with a range of 3000~4000Å have the longest wavelength among ultraviolet rays, so they are also called Lang Wave and commonly called UV-A. 2) Ultraviolet with a range of 2800~3200Å is called Middle Wave because it is the middle part of the UV wavelength, and it has a strong Suntanning Effect between 3000~3200Å. It is commonly referred to as UV-B. 3) Ultraviolet with a range of 1800~2800Å is also called Short Wave because it has the shortest wavelength among ultraviolet wavelengths. As a singularity, at this time, there is an effect of forming ozone (O3) in the 1000-2000Å band.

In the embodiment of the present invention, it is particularly preferable that the UV-C lamp 501 for generating an ultraviolet wavelength in the 1000 to 2000 Å band is provided in the secondary sterilization unit 50 . When the UV-C lamp 501 is used, there is no gas generation as in the chlorine sterilization method, there is no corrosiveness or toxicity, there is no increase or decrease of PH, and toxic substances cannot be generated even by reaction with external substances. In particular, the UV-C lamp 501 can almost completely purify the polluted smoke 5 because ozone is generated, so it is particularly suitable for the present invention.

[Figure 2]

[Figure 2] shows the exhaust duct cleaned using UV-C lamp (501). This is the appearance when the UV-C lamp 501 is irradiated on the exhaust duct shown in [Fig.

The sliding means 503 may be disposed on the second partition wall 303 and may be discharged in a lateral direction of the hood 1 . In this case, the UV-C lamp 501 is preferably disposed on the sliding means (503). In addition, the sliding means 503 may be provided with a protective cover (5011). The present embodiment described above has the advantage of a structure in which the UV-C lamp 501 does not come into contact with oil or water so that the protective cover 5011 is not required, but accidents such as discharge or short circuit with a small amount of water flowing into the cavity B generation?? Therefore, a protective cover 5011 surrounding the UV-C lamp 501 may be provided on the sliding means 503 .

The sliding means 503 may be engaged with the guide groove formed on the upper portion of the second partition wall 303 to be discharged to the side surface of the hood 1 . The sliding means 503 has a hardness formed on the front surface where the UV-C lamp 501 is provided, so that when the UV-C lamp 501 is mounted, the irradiation angle is widened so that the entire B cavity can be irradiated with ultraviolet rays.

The injection port 70 may be drawn into the lower surface of the primary sterilization unit 30 to spray water in an upward direction. The drain port 90 is connected to the lower surface of the hood 1 , and the injection hole 70 is disposed inside the hood 1 , and the water circulated inside the hood 1 may be discharged. The injection port 70 penetrates through the drain port 90 and is exposed to the lower surface of the primary sterilization unit 30 . A fixing clamp 901 may be provided at the drain 90 , and the fixing clamp 901 may be fixed such that the injection hole 70 faces upward.
