Description

Portable cooking fume hood

[0001] The present invention relates to an air purification device that absorbs and purifies smoke generated from a cooking vessel, and more specifically, to a portable cooking fume hood that can absorb and purify oil components and fine dust, liquefy and discharge oil components through cooling, and is capable of separating the cover and filter to make cleaning, replacement, and maintenance easier.

[0002] Typically, grilling places create an unpleasant atmosphere due to the smoke generated from the grill. Furthermore, the smoke carries with it the oil from the meat, polluting the interior. The oil's components can impart an odor to both the griller and the person grilling. Grilling meat or fish, in particular, generates a lot of smoke, exposing those around the grill to the smoke. This can lead to the smell permeating their clothes, as well as the oily residue, making them extremely uncomfortable.

[0003]

[0004] Therefore, in order to quickly remove or ventilate the smoke and preserve the flavor of the meat, grilling establishments are equipped with ventilation devices. Representative examples include a method of directly connecting the burner to the chimney, such as Utility Model Application No. 20-1984-0002609, “Bulgogi Grill with Odor and Smoke Removal Device,” or a method of installing an external chimney on the top of the burner, such as Smoke Exhaust Induction Device for Meat Grilling Application No. 20-1987-0014443.

[0005] However, this method of directly connecting to the burner requires excessive power to suck in the smoke and has the problem of poor efficiency, and the upper flue method increases the installation cost significantly, the device is too bulky and inconvenient to handle, and during the process of discharging the smoke, the oil component contained in the smoke gets on the surface of each tube, causing the inside to become contaminated and shortening the lifespan of the device.

[0006]

[0007] To solve these problems, the applicant of the present application filed an application for an 'air purification hood' in patent application number 10-2023-59149 on May 8, 2023, and the present invention proposes a 'portable cooking fume hood' that is a further improvement of the application.

[0008] The purpose of the present invention is to provide a portable cooking fume hood that can absorb and purify oil components and fine dust, and can discharge the absorbed oil components by liquefying them through rapid cooling.

[0023] The above portable cooking fume hood is structured so that smoke sucked in through the front moves inward by a fan provided at the inner front end of the front cover (30), and then oil components and fine dust contained in the smoke are filtered out by a plurality of filters, and the purified smoke is discharged to the outside by a fan provided at the inner rear end of the exhaust cover (60).

[0024]

[0025] On the lower rear side of the body (10), as shown in Fig. 2, a connection part (12) is formed for supplying power by connecting a power cord, and on the upper rear side, a function lever (13) is provided to perform various functions such as turning the power on / off, controlling suction power, and LED lighting, and between the connection part (12) and the function lever (13), an oil pan (80) is provided that is detachably connected to the inside of the insertion part (14).

[0026]

[0027] The above body (10) has a cone shape with a large diameter at the lower side that is settled on the ground as shown in FIG. 3 and a diameter that becomes smaller as it goes upward. A guide part (11) extending up and down is formed on the upper front side of the body (10), and a rotation cover (20) configured to be able to rotate up and down by connecting a rotation shaft (21) to a hinge part (22) on the upper side of the body (10) is provided.

[0028] A front cover (30) is coupled to the front of the above-mentioned rotary cover (20), a suction cover (31) is coupled to the rear inner side of the above-mentioned front cover (30), and a suction fan (32) is coupled to the inner side of the above-mentioned suction cover (31) so as to be able to rotate around the central part of the rotary cover (20) by a rotation shaft.

[0029] On the lower side of the front cover (30), a guide (30a) inserted into the guide part (11) of the body (10) is formed with the front side forming an arc shape, and on the inner circumferential surface of the front cover (30), an inlet (30b) communicating with the inner side of the guide (30a) is formed.

[0030] A front filter (40) and a filter cover (41) are combined on the front inner side of the front cover (30), and a plurality of filters are installed on the inner side of the front filter (40) and sealed by the filter cover (41), and the front filter (40) and the filter cover (41) are configured to be detachable from the front cover (30), thereby facilitating cleaning and replacement of the filter.

[0031]

[0032] As shown in Fig. 4, a fixing portion (40a) is formed on the back surface of the front filter (40) to which a pair of elastic portions (41a) formed on both sides of the filter cover (41) are fixed, so that it can be easily attached and detached, and a nozzle (40b) that is inserted into the inlet (30b) of the front cover (30) is formed protruding on the lower side of the front filter (40).

[0033]

[0034] Fig. 5 sequentially shows a plurality of filters installed on the inside of a front filter (40). Two oil barrier grease filters (50) are installed on the front, a carbon filter (51) is installed on the back of the oil barrier grease filter (50), and an activated carbon filter (52) is installed on the back of the carbon filter (51).

[0035] The above oil barrier grease filter (50) and carbon filter (51) can be used semi-permanently by separating them from the front filter (40), washing them with water, and drying them. The smoke generated during cooking is sucked in by the suction fan (32) to adsorb oil particles.

[0036] The configuration and operation of the above oil barrier grease filter (50), carbon filter (51), and activated carbon filter (52) have been described in detail in patent application number 10-2023-59149 previously filed by the applicant of the present application, so a detailed description thereof will be omitted below.

[0037]

[0038] In the present invention, a cooling element (53) is added to the back surface of an activated carbon filter (52) so that the oil component adsorbed on the filter can be quickly cooled and liquefied, thereby allowing it to be discharged through a nozzle (40b).

[0039] That is, the oil component adsorbed on the oil barrier grease filter (50) and carbon filter (51) is cooled by the cooling element (53) and liquefied, thereby falling through the nozzle (40b) inserted into the inlet (30b) of the front cover (30), and the fallen oil falls into the oil receiver (80) through the discharge port (15) formed to communicate with the guide (30a) on the upper side of the insertion portion (14) as shown in FIG. 6.

[0041] Meanwhile, a rear cover (60) is coupled to the back surface of the rotary cover (20) as shown in FIG. 3, and an exhaust cover (61) and an exhaust fan (62) are coupled to the rear inner side of the rear cover (60), a rear filter (70) and a filter cover (71) are coupled to the front inner side, and an activated carbon filter (52) is detachably installed on the inner side of the rear filter (70) to purify the sucked air and discharge it back to the outside.

[0042] Between the above exhaust fan (62) and the rotary cover (20), a center cap (23) is firmly fixed to the rotary cover (20) by a fixing pin (23a), and the center cap (23) is inserted into a groove formed concavely in the center of the exhaust fan (62), thereby supporting the exhaust fan (62) so that it does not vibrate up and down or left and right when it rotates.

[0043]

[0044] The present invention is configured so that the cover (20) (30) (60) can be rotated downward by a guide (30a) inserted into the guide portion (11) as shown in FIG. 7, thereby tilting the front cover (30) toward cooking vessels of various sizes and shapes to maximize smoke intake, and at this time, the guide (30a) rotates downward without shaking and without being separated left and right along the guide portion (11), thereby providing a smoother rotational motion and solid durability.

[0045]

[0046] The portable cooking fume hood of the present invention configured as described above has a suction fan (32) and an exhaust fan (62) provided on the front cover (30) and the rear cover (60), so that the smoke generated during cooking is quickly sucked in, purified, and then discharged, thereby preventing indoor air contamination by food smoke, and discharging purified air, thereby having the advantage of performing the function of an air purifier.

[0047] In addition, by configuring the oil barrier grease filter (50) and carbon filter (51) that can be washed and used, and the activated carbon filter (52) that can be replaced, to be removable, oil components and fine dust can be removed at the same time, and maintenance is more convenient because it is easy to wash, and the maximum amount of smoke can be quickly inhaled by the guide (30a) that rotates the cover (20), (30), and (60).

[0048] In addition, the cooling element (53) that quickly cools the oil component adsorbed on the oil barrier grease filter (50) and carbon filter (51) transfers the liquefied oil to the nozzle (40b) and collects it in the oil collector (80), thereby making the maintenance of the hood easier.
