Description

Cooker with deodorizer {Cooker having deodorizing apparatus}

The present invention relates to a cooking appliance provided with an odor removing device. More particularly, the present invention relates to a cooking appliance provided with an odor removing device configured to suppress the occurrence of food odor during cooking by collecting and removing food odor generated during cooking.

Cooking utensils are widely used in everyday household life, and are widely known by domestic and overseas manufacturers in large quantities and can be purchased and used commercially. It can have shape and size. As shown in FIG. 1, such a cooking appliance is usually provided with a main body 1 having a closed bottom and an upper end of the main body 1 in order to facilitate the input of the contents to be cooked and the withdrawal of the cooked contents after cooking. Consists of a lid (2) to cover the opening formed in the, the lid (2) is formed by a simple punching steam outlet (3) for adjusting the air pressure inside during cooking.

However, the conventional cooking utensils of the lid 2 and the main body 1 maintain the gap so that the lid 2 can be easily detached from the main body 1 by pressing a metal plate or the like. It is designed to be placed on its own weight, but the thickness of the metal plate itself can be deformed by external force during handling, so that deformation of the lid 2 or the main body 1 is not easy to attach or detach the lid 2. In addition, since the metal constituting the lid 2 has a high thermal conductivity, a separate plastic having a lower thermal conductivity than the metal plate in the center of the lid 2 so that the lid 2 can be easily opened in a heated state after cooking. Since the handle 4 has to be mounted, there is a problem that the productivity of the lid 2 itself is lowered.

However, a problem larger than the above-mentioned problems is that in the case of the conventional lid 2, the steam outlet 3 is formed by perforating the lid 2 in order to discharge the steam generated during cooking.

Conventional steam outlet (3) formed by a simple perforation had a problem that the smell is released from the food cooked with steam.

Odor emitted from the food to be cooked is itself a scattering of low molecular weight substances into the air, a loss of active ingredients in the food, and also in the space in which the cooking proceeds due to the release of odor during cooking It is perceived by the human sense of smell. The sense of smell is known to be the most fatigued organ in the body's senses, and in fact, persistent smells cause numbness of the sense of smell, and you can no longer feel the smell above a certain threshold.

Therefore, it is empirically known that the cooker actually desires to eat the food after cooking.

In particular, the odor-causing substances that occur during cooking of food are mainly components such as fat or protein, and they float in the air and stick to anywhere in the living environment such as walls, floors, ceilings, clothing, curtains, and so on. There was a causal problem.

Accordingly, the present inventors have completed the present invention by developing a cooking appliance equipped with an odor removing device to remove odor emitted during cooking.

It is an object of the present invention to provide a cooking appliance equipped with an odor removing device that can remove odors that may be generated during cooking.

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

As schematically shown in Figure 2, the cooking appliance equipped with an odor removing device according to the present invention is to cover the main body 1 to which the food to be cooked is a porous membrane made of water-repellent fibers in the lid (2) ( 8), the coolant is put into the inner container 22 formed thereon to cool and condense the odor-causing substances in the vapor evaporated and scattered into the atmosphere via the porous membrane 8 to suppress the release into the atmosphere. Characterized in that.

The main body 1 into which the food is put may be understood to be the same as or similar to the main body 1 of the conventional cooking utensil. The main body 1 is mainly made of metal and is directly placed on a heat source to directly heat and cook the food contained therein. . Covering the main body (1) includes a lid (2) mainly formed of metal, the lid (2) is equipped with an odor removing device.

The odor removing device may be provided in the lid 2 in the following configuration.

A circular rib 7 having a plurality of lattice-shaped grooves 6 formed therein is formed to protrude upward while having an inner space penetrating vertically in a part of the lid 2. The circular rib 7 may be integrally formed with the lid 2, and a plurality of lattice grooves 6 are formed in the circular rib 7. The grid-shaped groove 6 is placed on the porous membrane 8 described later.

The porous membrane (8) is laminated on the lattice groove (6) in the circular rib (7) with the membrane fastener (9) to function to filter the material discharged to the outside during cooking, it is made of water-repellent fibers. The water-repellent fiber is processed into a membrane of woven or nonwoven fabric, and about 0.2 μm of vapor through holes are formed at about 1.5 billion per square centimeter, porosity of about 82%, and water pressure of 4 to 7 kg / cm ^2. The moisture permeability (based on 24 hours) is 2g / cm ² , the contact angle with respect to water can be preferably used to about 118 degrees. The porous membrane 8 made of a water-repellent fiber material has a property of easily passing molecular water vapor at the same time without permeating water droplets having large particle sizes, and having water repellency due to a large contact angle with water. It does not stick to the porous membrane 8 made of processed fibers with water droplets, and is easily separated from the porous membrane 8 and does not remain. As a raw material of the water-repellent fibers constituting these porous membranes, a resin selected from the group consisting of fluororesin, polyvinyl chloride, polypropylene, polyvinyl alcohol, polycarbonate, and the like may be used. The water-repellent fibers as the porous membrane 8 made of the water-repellent fibers can be selected and used among those commercially traded under trade names such as 'Gore Tex' or 'Zitex'. In addition to Gore-Tex and Zytex, water-repellent fibers with similar characteristics are mass-produced and commercially supplied by leading manufacturers, and can be appropriately selected and used by those skilled in the art. Is easily understood.

The porous membrane 8 may be fixed by the membrane fastener (9). The membrane fastener 9 is for preventing the porous membrane 8 made of the water-repellent fiber from being separated from the circular ribs 7 by water vapor pressure, and also similar to the lattice groove 6, and is generally lozenge-shaped. A plurality of holes may be formed so as to cross the rod-like ribs with each other, but like the lattice grooves 6, they are not necessarily limited to the shape of the rhombic hole as described above. It is obvious to those skilled in the art that similar variations can be used to achieve the same purpose.

The porous membrane 8 and the membrane fastener 9 may be fixed to prevent the separation by the separation preventing device (10). The departure prevention tool 10 may be integrally fixed to the upper end of the circular rib 7 by a conventional method such as ultrasonic fusion as shown in FIG. 3 according to one specific embodiment of the present invention.

A heat resistant o-ring 11 may be interposed between the porous membrane 8 made of the water-repellent fiber and the lattice groove 6, which smoothly supports the porous membrane 8 made of the water-repellent fiber. At the same time it serves to increase the sealing between the lattice groove 6 and the porous membrane (8). The O-ring 11 may be manufactured using a heat resistant elastic material such as silicone resin.

The outer container 21 is to insulate the inner container 22 containing the coolant from the atmosphere to maintain the cool air for a long time, and is integrally fixed to the outer wall of the circular rib 7.

The inner container 22 is also fixed to the outer wall of the circular rib (7) as well as the outer container 21 is fixed to be located in the outer container 21, the coolant is received therein and discharged through Cooling of the odor causing substances generated during cooking of the food from the vapor to prevent the odor causing substances to be diffused into the atmosphere, thus the odor can be removed.

The coolant contained in the inner container 22 may be selected from the group consisting of water, ice, salt, and the like, and in the case of ice water, to further reduce cold air and to add salt as an electrolyte to maintain cold air for a long time. It is to be understood that such coolants are also known to the extent that they will be readily understood by those of ordinary skill in the art.

The inner container 22 and the outer container 21 may be covered by a single cover 23 to be sealed, and a vent 24 is formed at the center of the cover 23, so that the inside of the main body 1 It is configured to discharge the vapor pressure due to the heat applied during cooking of the food into the atmosphere.

Therefore, when the food to be cooked is placed in the main body 1, the lid 2 provided with the odor removing device is covered, and the main body 1 is heated to cook the food, steam and odor causing substances are heated during the heating. It is discharged from the food in (1), and at the same time, the expanded air by heating is discharged together. The water vapor and the odor causing substance are introduced into the inner container 22 via the porous membrane 8 fixed in the circular rib 7. The inner container 22 contains a coolant to liquefy or solidify water vapor and odor causing substances. The liquefied or solidified water droplets or odor causing substances are not introduced into the main body 1 again by the porous membrane 8, and remain in the inner container 22 as they are. However, only air that is not liquefied or solidified by the coolant may be discharged into the atmosphere through the air vent 24 formed in the center of the cover 23.

For example, when trimethylamine is described as a representative component of the odor causing substance, the boiling point of this component is about 124 ° C and the melting point is 35 ° C. Thus, the food may be heated during cooking and diffused into the atmosphere, but may be solidified by contact with a coolant maintained at approximately 0 to minus 25 ° C., and once solidified, may not diffuse into the atmosphere. In particular, in the case of frying, since the heating to a high temperature of about 180 to 200 ℃ may be intensified, the present invention will be able to solidify and remove it by the coolant.

In particular, a rubber packing 25 may be further mounted on the upper end of the inner container 22, and the rubber packing 25 may maintain airtightness when the inner container 22 is covered by the cover 23. It serves to suppress the release of the coolant, water vapor or odor causing substances contained in the inner container 22 to the outside.

In the present invention, it is also possible to mount the non-return plate 16 of the elastic material in place of the membrane fastener 9, as shown in Figure 5, the non-return plate 16 is connected to the disc of the elastic material on one side (18) is formed to form a cut line 17 in a circular shape, which can be formed so that the inner portion can be varied with respect to the edge portion by making a circular cut using a blade by a conventional press working or the like. As such, the non-return plate 16 of the elastic material can be easily understood by those skilled in the art, and may be purchased and used commercially.

In addition, according to another specific embodiment of the present invention, the release preventing device 10 may be formed to have a thread 14 protruding downward toward the bottom thereof, as shown in FIG. The screw groove 15 formed on the inner circumferential surface of the rib 7 may be detachably mounted by screwing.

In addition, by applying a conventional coupling method, such as the use of a separate fastener such as a screw, it is also possible to couple the phase departure prevention tool 10 and the circular rib 7 to each other, the departure prevention tool 10 and the circular The coupling between the ribs 7 is also possible by the application of other coupling methods and the like, which can be easily understood by those skilled in the art, and the present invention provides these separation preventing devices 10 and circular ribs. It is obvious that it is not limited by the method of joining (7).

It can be understood that the handle 12 is merely for ease of gripping and handling.

In addition, a rubber packing 13 may be attached to an edge of the lid 2, and the rubber packing 13 may be made of the same or similar material as the O-ring 11, and may be made of a heat-resistant elastic material such as silicone resin. It can be produced using.

The rubber packing 13 serves to tightly seal between the lid 2 and the main body 1 of the cooking utensil according to the present invention so that water vapor containing a cooking smell of food is not discharged elsewhere.

In addition, according to another embodiment of the present invention, as shown in FIG. 6, instead of the porous membrane 8, the conical body 26, the beads 27 and the fine mesh net 28 accommodated therein. A check valve made can be used. It can be understood that this check valve also has a function of allowing the movement of the gas upwards and, on the contrary, suppressing the downward movement of the liquid or solid phase coolant or the like. In particular, the fine mesh net 28 for preventing separation from the conical body 26 of the beads 27 and making gas into a fine bubble is fixed to the upper portion of the conical body 26 by the mantle fixture 29. Can be.

Therefore, according to the present invention, the odor causing substance generated during cooking together with water vapor is cooled by the coolant contained in the inner container 22 constituting the odor removing device provided in the lid 2 covering the main body 1 to liquefy or solidify. By suppressing the diffusion of the substance as the odor as it is to the atmosphere there is an effect that can suppress the smell during cooking.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
