Description

An air purifier for oil vapor and an oil vapor filter {AIR PURIFIER FOR OIL MIST AND OIL MIST FILTER}

The present invention relates to an oil vapor air purifier and an oil vapor filter for removing oil vapor generated during food cooking. is about

Demand for air purifiers has grown at an average annual rate of 12% or more since 2012 due to the deterioration of air quality such as fine dust and ultrafine dust for several years. On the other hand, when cooking at home, heated oil is vaporized and the oil mist suspended in the air in the form of a mist acts as a carcinogen together with ultrafine dust, making it difficult for non-smokers to develop lung cancer. It is also considered to be the main cause.

However, existing air purifiers mainly focus on supplying clean air by filtering fine and ultra-fine dust in the atmosphere. Discontinue use and advise to cook. This is because the oil vapor in the air sticks to the air purifier filter in the form of oily grease, and the lifespan of the filter is drastically shortened and furthermore, it causes the failure of the air purifier.

Accordingly, recently, several air purifiers dedicated to the kitchen for filtering oil vapor have been proposed. However, in all of the previously proposed technologies, the oil vapor filter is installed inside the housing that forms the exterior of the air purifier, and the sensor detects the contamination of the filter installed inside to inform the replacement time, etc. There was a problem in that it was impossible to accurately determine the contamination of the oil filter only when a separate sensor configuration was required to detect the contamination or when used in combination with the main filter sensor for fine dust filtration.

1 schematically shows the external structure of an air purifier for oil vapor according to an embodiment of the present invention. The air purifier for oil vapor according to the present invention, like a conventional air purifier, includes a housing having an air inlet and an air outlet, a blower fan for flowing air so that air is introduced into the inlet and discharged through the outlet, and the air inside the housing It consists of a configuration including at least one or more filter materials mounted on the flow path. In this configuration, the air purifier for oil vapor according to the present invention includes an air intake port provided on a first surface of the housing, and an oil vapor filter as the at least one filter material, wherein the oil vapor filter is a first surface of the housing. It consists of a configuration in which the front surface of the oil vapor filter is completely exposed to the outside on the air intake surface of the

Specifically, as shown in FIG. 1 , in the air purifier for oil vapor according to the present invention, the first surface 110 of the housing 100 has an opening 114 functioning as an air inlet and a frame 112 surrounding the opening. ) shape, and has a structure in which the oil vapor filter 210 is exposed to the outside through the opening 114 to filter oil vapor in the air. In other words, the present invention may be configured in a configuration in which the oil vapor filter is directly exposed on the inlet through which air is first introduced, that is, the opening 114 in a completely open form. This is to enable the user to easily check whether the oil vapor filter is contaminated with the naked eye by providing the oil vapor filter so that the entire surface is exposed to the outside.

In addition, as shown in FIG. 9 , the oil vapor air purifier of the present invention has a housing 100 that forms the exterior of the air purifier, including a polyhedron, and has various shapes such as conical, cylindrical, and water drop shapes, and the oil vapor By configuring the filter 210 with a material having elasticity, the oil vapor filter may be configured to cover the suction port surface by adapting to the shape of the various housings. That is, the present invention is characterized in that the front surface of the oil vapor filter is completely exposed to the outside on the air intake port formed on the surface of the housing. However, the structure may be adopted without limitation.

FIG. 2 exemplarily shows a structure in which a filter material is installed inside the housing 100 according to an embodiment of the air purifier for oil vapor shown in FIG. 1 . As shown, a mesh filter 220 is mounted inside the housing 100 adjacent to the rear surface of the oil vapor filter 210 installed so as to be exposed to the first surface 110 of the housing, and the oil vapor as the mesh filter 220 is It can function as a support for the filter and at the same time allow the residual oil vapor to condense through the temperature difference. To this end, the mesh filter is preferably made of a metal material. In the case of a typical air purifier, the mesh filter is configured to be disposed at the forefront of the filter material, but in the air purifier for oil vapor of the present invention, the mesh filter 220 is positioned at the rear of the oil vapor filter 210 in consideration of the above functions. It has a design feature.

Then, on the air flow path between the metal mesh filter 220 and the blowing fan 300, a deodorizing filter 230 and a HEPA filter 240 that may contain activated carbon and zeolite may be selectively installed. have. Activated carbon and zeolite components of the deodorization filter can be effectively removed by adsorbing odors and harmful gases contained in the air, and can be replaced with materials with similar functions. It has the effect of removing The air purifier of the present invention essentially includes an oil vapor filter 210 and a mesh filter 220 , and at least one of the deodorizing filter 230 and the HEPA filter 240 may be optionally provided. These optional filters may include special filters according to the user's selection in addition to the deodorization filter and the HEPA filter.

As shown in FIGS. 6A and 6B, in order to easily attach and detach each of the above-mentioned filter materials to the inside of the housing, the user can easily attach and detach the desired types of optional filters in the desired arrangement order on the inside of the housing and each filter material. Demountable means (220a, 250a) such as a detachable groove and a handle may be provided respectively. Optionally, it is also possible to attach the filter using an easily detachable means such as a magnet. At this time, the special filters including the deodorizing filter 230 and the HEPA filter 240 mounted inside the housing are configured with the same size and structure, so that the user can easily arrange the filters in the desired order or add/remove filters. It is preferable to do

On the other hand, it is preferable that the inside of the housing has a pyramidal structure in which the longitudinal cross-sectional area of the air flow passage becomes narrower from the air intake port 114 side to the discharge port 124 side. That is, by designing the air intake, the filter material to which the filter material is mounted, and the blower fan to have a smaller longitudinal cross-sectional area in the order, the flow and purification of the introduced air are promoted, and consequently, the air purification efficiency can be improved.

An exemplary installation structure of the oil vapor filter of the present invention is described with reference to FIGS. 2 and 3 . 3 shows the structure of the frame 112 of the first surface of the housing formed so that the oil vapor filter 210 is exposed to the outside through the suction opening.

As shown in FIG. 3 , the lower frame 112b of the opening 114 formed on the first surface 110 of the housing 100 is positioned so that the suction opening is located at a height spaced apart from the bottom surface of the installation site by a predetermined distance. It has a width w extending a certain length from the bottom surface. The reason for locating the intake opening 114 for air containing oil vapor at a height spaced apart from the floor by a certain distance is a design in consideration of the use of the air purifier of the present invention to remove oil vapor generated during food cooking. In other words, when cooking food by placing a cooking pot or frying pan on a gas range or an electric range, the actual oil vapor is emitted upwardly from the bottom by the height of the cooking utensils and emitted upwards into the air. Accordingly, when the suction opening of the air purifier is effectively positioned in the area where the oil vapor is actually emitted, the oil vapor removal efficiency may be further improved. In consideration of this, in the present invention, the width w of the lower frame of the opening 112b is designed to match the height of the cooking pot, etc., so that the suction opening 114 is located at a height spaced a predetermined distance from the installation floor. There is one characteristic.

In addition, the oil vapor filter 210 wound in a roll shape is mounted inside the housing and inside the lower frame 112b having the width adjusted as described above. Specifically, the oil vapor filter 210 includes a portion in use installed on the first surface 110 of the housing so as to be exposed to the outside by the length of the intake opening, and an unused portion of a predetermined length continuously extending from the portion in use. In addition, the unused part is maintained inside the housing in a structure wound in a roll form as a replacement part when the part being used later becomes contaminated and replaced. That is, the oil vapor filter of a certain length including the replacement part is wound in a roll shape and mounted and stored inside the lower frame 112b inside the housing, and the part currently in use is released from the roll and exposed to the outside through the suction opening. is installed On the other hand, in the illustrated embodiment, the oil vapor filter is wound and accumulated in a roll form as an example, but the accumulation structure of the oil vapor filter is not limited thereto.

The configuration of the oil vapor filter 210 is not particularly limited as long as it is a configuration capable of filtering oil vapor of 1 to 10 μm, but preferably the first filter layer and the first filter layer are finer than the first filter layer coated on the first filter layer. It may be composed of a double structure consisting of a second filter layer of tissue. In addition, when the oil vapor filter in use becomes contaminated, it is easily removed from the accumulation structure and replaced with a new, unused oil vapor filter retained in the accumulation structure, the oil vapor filter of the present invention provides a predetermined amount over the entire extended length. It may include a perforated line in which an incision is formed in the form of a dotted line. Meanwhile, as will be described later, a cutting means such as a knife or a hot wire may be additionally provided at the outlet of the oil vapor filter to easily cut the used filter.

In addition, the oil vapor filter of the present invention may be configured to include a fiber filter layer, which may be composed of a non-woven fabric, and a pattern layer partially coated thereon. Here, the pattern layer is formed on the outer surface of the fiber filter layer in contact with the outside air among both surfaces. As shown in FIG. 4 , the surface 210a of the fiber filter layer may have a configuration in which a predetermined pattern is formed with a material 210c not contaminated by oil vapor or an oil vapor-friendly material 210b. 4 (a) shows a state in which the oil vapor filter is not contaminated by use, and FIG. 4 (b) is a case in which a material 210c not contaminated by oil vapor is partially formed on the surface 210a of the fiber filter layer. , the surface 210a of the fiber filter layer is contaminated by the use of an oil vapor filter, and the portion 210c on which the pattern is formed is not contaminated, indicating a state in which the pattern is clearly contrasted. In addition, FIG. 4(c) shows that when a pattern is formed on the surface 210a of the fiber filter layer with an oil vapor affinity material 210b superior in oil vapor adsorption performance, the surface 210a of the fiber filter layer by the use of an oil vapor filter The portion 210b on which the pattern is formed is further contaminated, indicating a state in which the pattern is visualized. In this way, it is also possible to form a pattern with a material having better oil vapor absorption than the fiber filter layer, for example, an oil paper material, so that the degree of contamination of the oil vapor filter can be checked by discoloration of the pattern portion. By configuring in this way, there is an advantage in that it is possible to determine the replacement time by easily distinguishing the contamination state of the entire filter with the naked eye. It is preferable that the pattern is partially formed within a limit that does not interfere with the function of the fiber filter layer, such as dots, lines, and patterns.

In addition, the oil vapor filter of the present invention may have a configuration in which a first filter layer made of nonwoven fibers and a second filter layer made of a finer structure than the first filter layer are formed on the first filter layer. At this time, the second filter layer is a filter layer through which the air that has passed through the first filter layer is additionally filtered, and is formed on the inner surface that does not come into contact with external air among both surfaces of the first filter layer, and includes a non-woven fabric or pulp material. It may be made of material. Since the first filter layer is made of a fine structure having smaller pores than the first filter layer, it is preferable to have a thinner thickness than the first filter layer, for example, 1 mm or less in order to minimize airflow obstruction. In addition, the oil vapor filter of the present invention has a predetermined pattern with a material that is not partially contaminated by oil vapor or an oil vapor-friendly material on the other surface on which the second filter layer is not formed among both surfaces of the first filter layer composed of nonwoven fibers. The formed pattern layer may be further provided. As described above, by additionally configuring the pattern layer using a material having different oil vapor adsorption performance from the first filter layer, there is an advantage in that the contamination state of the oil vapor filter can be easily distinguished with the naked eye to determine the replacement time.

Next, a configuration for replacing the contaminated oil vapor filter in the oil vapor air purifier of the present invention will be described with reference to FIGS. 1 and 5 . In each of (a) and (b) of Figure 5, the structure of the oil vapor filter outlet 116 according to the embodiment of the present invention is illustrated by way of example.

As shown in FIG. 1 , the end of the currently used oil vapor filter installed to be exposed through the opening 114 to the upper portion of the upper frame of the opening of the first surface 110 of the air purifier housing according to an embodiment of the present invention is a little bit out Specifically, as shown in FIG. 4A , an oil vapor filter outlet 116 in the form of a slit through which the used oil vapor filter can be discharged from the end is formed in the upper frame 112a of the upper frame of the opening 114 . It is configured to discharge the used oil vapor filter by pulling the exposed end upward through the oil vapor filter outlet 116 .

That is, in the present invention, when the used oil vapor filter is replaced, the oil vapor filter installed to be exposed through the opening slides upward along the frames on both sides of the opening and is discharged through the oil vapor filter outlet 116. are doing In this case, the upward sliding movement of the used oil vapor filter may be performed by the user pulling the filter end exposed to the upper part 112a of the upper frame. In addition, by selectively configuring a rotary knob on the outer side of the housing that is interlocked with the oil vapor filter roll holding means inside to unwind or operate the wound roll, and by operating the rotary knob so that the wound roll is unwound upward. It may be set to induce upward sliding of the used oil vapor filter and expose the unused oil vapor filter to the opening. It is preferable to appropriately select the specific exhaust mechanism of the oil vapor filter in consideration of specific materials such as tensile strength or stiffness of the oil vapor filter.

In addition, a guide means is provided inside the frame on both sides of the housing to stably guide the movement of the filter when the oil vapor filter slides upward, keeping the oil vapor filter moving slightly away from both edges of the rear surface of the oil vapor filter adjacent to the opening surface. can be The guide means may be formed in the form of projections 118 inside the frame on both sides of the housing as shown in FIG. There is no limitation, and it is also possible to have a structure formed to extend long along the inner side of the frame on both sides.

In addition, by utilizing the frictional force of the oil vapor filter, the oil vapor filter can slide and move upward without separating the first surface 110 of the housing having the opening formed thereon from the main body 120 .

On the other hand, the upper and lower views in (b) of FIG. 5 are views viewed from the planar direction and the front direction of the upper frame 112a of the opening 114, respectively, and the oil vapor filter outlet of the upper frame 112a of the opening. It shows a configuration in which the frame pollution prevention means 116a is provided on one side adjacent to the 116 . This is a means formed by different inclination from one side of the upper frame to prevent the front side of the contaminated filter from directly contacting one side of the upper frame when sliding the contaminated oil vapor filter upward for replacement of the oil vapor filter. It may be provided integrally or detachably with the frame 112a. The frame pollution prevention means 116a may be made of a material that is not easily contaminated by the adsorbed oil vapor, for example, may be made of the same material as the upper frame. The frame pollution prevention means may be used for supporting the perforated line when the oil vapor filter is cut along the perforated line. In addition, it is also possible to include a cutting means capable of cutting the oil vapor filter in the frame pollution prevention means 116a so that the contaminated use of the discharged oil vapor filter can be cut and removed through the cutting means.

In the above, the configuration related to the replacement of the oil vapor filter in the embodiment in which the accumulation structure of the oil vapor filter is provided as in the embodiment of FIGS. 1 to 5 has been described. However, as shown in FIG. 9, when the housing forming the exterior of the air purifier has a cylindrical shape, a conical shape, etc. and an elastic material oil vapor filter covers the intake surface, the used filter is pulled out of the housing when replacing the filter. It can be replaced by removing it and putting a new filter on it.
