Description

BACKGROUND

1. Field of the Invention

The present invention relates to an exhaust device and a cooking device comprising the same, and more particularly to an exhaust device used for the purpose of sucking and removing polluted air generated during a cooking process and a cooking device comprising the same.

2. Discussion of Related Art

In general, a kitchen is provided with a worktop in which a heating device such as an electric oven or a gas oven for cooking such as boiling or baking by applying high heat to food is arranged.

Here, an object to be cooked heated by a high heat of the heater arranged in the countertop generates pollutants such as smoke, odor and oil fume during heating. Such contaminants can float around due to the heat and spread around the kitchen or an indoor space. The contaminants distributed in this way present an unpleasant odor and cause a feeling of repugnance. In particular, in a closed kitchen, contamination becomes a factor lowering a worker's attention and detrimental to the worker's health.

Accordingly, a fume extractor is installed in the kitchen to discharge pollutants such as smoke, odors and oil fumes generated during cooking to the outside.

Such a fume extraction device can have a fume extraction body, which forms an outer shape of the fume extraction device, and a suction opening, which is formed in a lower side, and a fan, which is set up to generate an air flow for sucking the air into the fume extraction body and the air to the outside drain.

Also, the fume extractor device may further include a filter installed in the main body to filter the air sucked into the body and a pipe configured to form a channel for discharging the air sucked into the body to the outside after passing through passed through the filter.

The operation of the fume extractor device configured as described above is as follows.

Impurities are generated in the process where an item to be cooked is heated by a heating device on a countertop and rise or are forced to rise due to their own rising force, which is caused by an intrinsic temperature higher than the temperature of the surrounding air or due to airflow , which is formed by the fan of the extractor hood. The impurities that have risen in this way can flow through the filter and be discharged through the pipe connected to an external duct.

The range hood can suck air and debris to some extent near the suction port formed in the bottom of the hood body, but it is difficult for the range hood to properly suck air and debris far from the suction port. This is because the farther the air and contaminants are from the suction port, the more the flow velocity decreases as the inverse of the square of the distance from the suction port.

That is, in the conventional fume extractor device, the suction performance is rapidly reduced as the air and impurities are farther from the suction port, and an increase in the suction flow rate of an induced draft fan does not proportionally increase the collection efficiency of the impurities.

Nevertheless, the suction flow rate of the suction fan can be increased to increase a suction force of the extractor device, but in order to double the suction flow rate of the suction fan, the power consumption of the suction fan should be increased by a factor of 2 ³ , that is, by a factor of 8. Therefore, there is a problem that the power consumption is excessively increased and thus the noise is greatly increased.

Considering this aspect, it can be seen that the collection of pollutants is only carried out efficiently if the suction opening of the extractor hood is close to the source of the pollutants. That is, in order to effectively perform the collection of impurities, the range hood should be installed at the lowest possible position so that the suction port of the range hood can be as close as possible to the position where the item to be cooked is heated.

However, it is not easy to set the installation height of the range hood device to achieve the purpose of improving the collection efficiency of the impurities and the purpose of improving the cooking efficiency at the same time. For example, when the installation height of the fume hood is lowered, the collection efficiency of the impurities of the fume hood can be improved, but restrictions on cooking devices that can be placed on a heating device increase accordingly. That is, a lower installation height of the extractor device only allows the use of cooking devices at a low height.

Conversely, when the installation height of the range hood increases, cooking using high-altitude cooking appliances becomes possible, but the distance between the source of impurities and the suction port of the range hood increases accordingly, and thus the possibility is high that the collection efficiency of the Contamination of the extractor device decreases.

In recent years, the use of range hoods integrated in the cooking area (downdraft range hood) instead of a range hood installed on the ceiling has gradually become more widespread because of advantages in terms of space utilization and design.

A range hood integrated into the cooking area is installed in a heating device such as an electric oven or installed in a kitchen island itself instead of being installed on the ceiling. The extractor hood integrated into the cooking area is superior to a extractor hood installed on the ceiling in terms of space utilization and design.

Prior art document 1 (European Patent Application Laid-Open No. 3553388) discloses an example of an extractor hood integrated into the cooking area.

With reference to 14 and 15 For example, a downdraft extractor (21) disclosed in prior art document 1 may be installed in a countertop (4) provided with a cooking surface (22). The downdraft extractor (21) can be installed on the cooking surface (22) or installed adjacent to the cooking surface (22).

The downdraft extractor (21) can have a vapor extraction body (213) and a suction opening (212) can be formed in a front side of the vapor extraction body (213).

The extractor body (213) may be provided in the form of a box protruding upwards from a top of the cooking surface (22) forming a plane. For example, the hood body (213) may be provided in the shape of a box whose front and rear dimension is shorter than the widthwise dimension thereof.

Also, the suction port (212) may be formed to pass through the front of the hood body (213) in the front and rear direction. Impurities produced by a cooking device arranged on the worktop (22) can be sucked into the extractor body (213) via the suction opening (212) which is arranged behind the cooking device. The impurities can be sucked in downwards in the extractor body (213). The downdraft extractor (21) disclosed in prior art document 1 may be provided to be able to move up and down with respect to the cooking plate (22).

The downdraft extractor (21) can move up and protrude to an upper portion of the worktop (4) in a state of being inserted into a lower portion of the worktop (4) and in such a state of protruding to the upper The downdraft extractor (21) can suck in the impurities in the area of the worktop (4).

Likewise, the downdraft extractor (21) can move down to the lower portion of the worktop (4) and be reinserted into the lower portion of the worktop (4).

The downdraft extractor (21) can also provide a function of a display device. i.e. a kitchen appliance (2) disclosed in prior art document 1 may be the downdraft extractor (21), a display device (20) or a device having the functions of both the downdraft extractor (21) and the display device (20) has, be.

The display device (20) of the prior art document 1 may have an extension element (201). The extension element (201) can be provided on the extractor body (213) or the extractor body (213) itself can be the extension element (201).

An imaging surface element (207) can be formed in the extension element (201). The imaging sheet (207) can be formed by a surface treatment of a plastic or glass plate, can be formed by a transparent refractive sheet sandwiched between a plurality of extension members (201), or can be formed by a screen mounted on the extension member (201). is trained.

A projector (3) can be installed on the cooking surface (22). The projector (3) can output an image toward the imaging sheet (207), and the image output from the projector (3) can be projected onto the imaging sheet (207). When the image output from the projector (3) is projected onto the imaging sheet (207), digital content can be output onto the display device (20).

In prior art document 1, the suction port (212) and an imaging surface member (215) are provided together on the hood body (213). i.e. the suction port (212) is provided at a lower end portion of the front of the fume hood body (213), and the imaging sheet (215) is disposed above the suction port (212). As an example, the imaging sheet (215) may be provided on the fume hood body (213) and provided in a shape covering the entire upper surface of the suction port (212).

The steam generated by the cooking device placed on the cooking surface (22) can move backwards towards the suction port (212) and can be sucked into the downdraft extractor (21) through the suction port (212).

The vapor moving rearwardly toward the suction port (212) as described above may become an obstacle blocking viewing of the screen output via the display device (20) from the front.

That is, if the vapor moving backwards towards the suction opening (212) blocks the view of the display device (20) from the front or interferes with the image output of the projector (3), there can be a problem in that the visibility of the screen output is reduced via the display device (20). Also, when the steam moving rearward toward the suction port (212) comes into contact with the front of the hood body (213) as described above, a phenomenon in which water drops are deposited on the front of the hood body ( 213) form.

The water drops that are formed on the front of the extractor body (213) can disturb the screen output via the display device (20) and can reduce the visibility of the corresponding screen.

Moreover, in the prior art document 1, the display device (20) is arranged behind the cooking surface (22) and accordingly the screen is output from behind the cooking surface (22). Accordingly, in a state where a cooking device is placed on the cooking surface (22), part of the screen output from the display device (20) is obscured by the cooking device, and thus a problem may arise that the screen output on the display device (20) is not is correctly visible.

Also, the odor filter may be made of activated carbon or the like that removes odor, and the dust filter is a filter used for removing particulate matter. The active filter can improve the performance using plasma, UV light or the like, which decomposes the odor molecules to a greater extent without releasing any impurity such as ozone.

The filter 145 can be any of the above filters or can be a combination of the above filters.

Meanwhile, the main body 110 may have a body front 111 and a body back 113 . The body front 111 is arranged in front between the body front 111 and the body back 113 and may form an outside of the front of the main body 110 . Also, the body rear 113 is located between the body front 111 and the body rear 113 behind and may form an outer side of a rear of the main body 110 .

The body front 111 and the body rear 113 may be arranged in the front-rear direction with the exhaust air flow path 110a interposed therebetween. That is, the body front 111 may be located in front of the exhaust air flow path 110a, and the body rear 113 may be located behind the exhaust air flow path 110a can be arranged. In other words, the exhaust air flow path 110a may be arranged between the body front 111 and the body rear 113, which are arranged to be spaced a certain distance from each other in the front-rear direction.

An upper portion of the exhaust airflow path 110a may be clad by a body top 115 . The body top 115 may be coupled to the body front 111 and the body rear 113 from above, and may cover the exhaust flow path 110a from above.

The main body 110 configured as described above may be provided to be able to move up and down. The main body 110 may move up and protrude above the worktop 111 from the top panel 23 , or may move down and be accommodated in the space formed below the worktop 11 and the top panel 23 .

A space of a certain volume capable of accommodating the exhaust duct 140 and the main body 110 may be formed under the countertop 11 and the top plate 23, i. H. in the body 10. The main body 110, which has moved down under the countertop 11 and the top plate 23, can be accommodated in the space in the body 10. Also, an upper end of the main body 110 thus moved downward can be inserted into the body 10 so as not to protrude from the countertop 11.

Furthermore, at least a portion of the main body 110 which has been moved down into the body 10 as described above can be inserted into the exhaust duct 140. For example, the main body 110 can move up and down in a state where at least a portion of the main body 110 is inserted into the exhaust duct 140 . Here, a lower end of the exhaust air flow path 110a may be connected to the exhaust air duct 140 in the exhaust air duct 140, and accordingly the exhaust air flow path 110a and the exhaust air duct 140 may be connected.

Meanwhile, the exhaust device 100 of the present embodiment may further include a display 120 . The display 120 may be provided to output an image on the main body 110 . Here, the image output from the display 120 may be in a form including at least one of text and images.

When the main body 110 moves up and down, the positions of the suction port 112 and the display 120 may change as well. When the main body 110 moves up and protrudes above the worktop 111 and the top plate 23, the worktop 11, the suction port 112 and the display 120 can also be placed above the worktop 11 and the top plate 23. When the main body 110 moves down and is inserted into the body 10, the suction port 112 and the display 120 are arranged in the body 10 as well.

[Arrangement Structure of Suction Port]

As described above, the suction port 112 may be provided in the main body 110 . The suction port 112 may be arranged on a front side of the main body 110 or arranged on a side surface of the main body 110 . In the present embodiment, the suction port 112 is exemplified as being arranged at a front side of the main body 110 .

The suction port 112 located at the front of the main body 110 may be formed at the front of the body 111 . The suction port 112 may be formed to penetrate through the body front 111 in the front and rear direction. A rear side of the suction port 112 formed in this way may be connected to the exhaust air flow path 110a in the main body 110, and a front side of the suction port 112 may be opened toward the front side of the main body 110.

According to the present embodiment, the suction port 112 may be arranged at the front of the main body 110 and may be arranged at a position shifted in the lateral direction. In other words, the suction port 112 may be arranged at a position closer to a side end portion of the main body 110 than to a side center of the main body 110 .

Specifically, the suction port 112 may be arranged at a position further from the lateral center of the main body 110 than the cooking surfaces 23a and 23b in the lateral direction.

Also, a pair of suction ports 112 may be arranged at the front of the main body 110 in the lateral direction. Any one of the pair of suction ports 112 may be located at a position further offset to one side in the lateral direction from the cooking surfaces 23a and 23b, and the other of the pair of suction ports 112 may be located at one position more to the other side in the lateral direction from the cooking surfaces 23a and 23b.

That is, the cooking surfaces 23a and 23b may be disposed between the pair of suction ports 112 arranged in the lateral direction, and each of the suction ports 112 may be disposed between the lateral end portion of the main body 110 and the cooking surfaces 23a and 23b or between the other side end portion of the main body 110 and the cooking surfaces 23a and 23b. The pair of suction ports 112 can be described as being located on outer sides of the cooking surfaces 23a and 23b in the lateral direction.

Furthermore, compared to the display 120, the suction port 112 can be arranged at a position farther from the lateral center of the main body 110 in the lateral direction. Specifically, the display 120 may be arranged between the pair of suction ports 112 arranged in the lateral direction.

Each of the suction ports 112 may be disposed between one side end portion of the main body 110 and the display 120 or between the other side end portion of the main body 110 and the display 120 . The pair of suction ports 112 can be described as being located on outer sides of the display 120 in the lateral direction.

Contaminated air generated by a cooking device placed on top of the heater 20 may be collected by the exhaust device 100 placed behind. Since the suction ports 112 are arranged on the outer sides of the cooking surfaces 23a and 23b and the display 120 in the lateral direction as described above, the polluted air can be collected by the exhaust device 100 at a position that is toward an end portion of the exhaust device 100 in the lateral direction instead of being collected on an outside of the exhaust device 100 in the lateral direction.

For example, the polluted air from a cooking device placed on the heating device 20 may move backward to be offset toward any direction along the lateral direction and sucked into the exhaust device 100, or may be divided to both sides and into the Exhaust device 100 are sucked.

In particular, the polluted air generated from a cooking device located at a position offset to the left side of the heater 20 may move in a direction between a left direction and a rear direction and may be introduced into the intake port 112 which is arranged on the left side of the exhaust device 100 .

Also, polluted air generated from a cooking apparatus located at a position offset to the left of the heater 20 may move in a direction between a rightward direction and a rearward direction and may be introduced into the intake port 112. which is arranged on the right side of the exhaust device 100.

Also, the polluted air generated from a cooking device arranged at a center of the heating device 20 may move in a lateral direction while being divided to both sides and may be introduced into each of the suction ports 112 arranged on both sides of the exhaust device 100 are. Accordingly, the polluted air can be sucked into the exhaust device 100 while the contact with the exhaust device 100, particularly the front side of the main body 111, is minimized.

Since collection of polluted air is performed as described above, an occurrence of a situation where the polluted air blocks the front view of the exhaust device 100, particularly the display 120, can be greatly reduced.

That is, since the polluted air generated near the left side of the exhaust device 100 can be collected from the left side of the exhaust device 100, and the polluted air generated near the right side of the exhaust device 100 can be collected from the right side of the exhaust device 100 , a problem in which the view of the display 100 is blocked by the polluted air can be dealt with effectively.

Also, when the dirty air collection is performed as described above, it becomes difficult for the dirty air to come into contact with the front side of the main body 110 .

As the contact between the main body 110 and the polluted air increases, the possibility of increasing contamination of the front side of the main body 110 increases. Soot, oil, etc. contained in the polluted air contaminate the main body 110 while moving are in contact with the main body 110, and thus the degree of contamination of the front side of the main body 110 can be increased and the visibility of an image output via the display 120 can be reduced.

Likewise, the contact between the front of the main body 110 and the polluted air causes condensation on the front of the main body 110. The condensation on the front of the main body 110 can not only contaminate the outside of the exhaust device 100, but also distort the image output via the display 120 and reduce the visibility of the corresponding image.

However, when the collection of polluted air is performed as described above, making it difficult for the polluted air to come into contact with the front side of the main body 110, it is not only easy to keep the outside of the exhaust device 100 clean but also the quality and visibility of an image output via the display 120 can be effectively improved.

Furthermore, the exhaust air device 100 can have a cladding. The trim is provided to trim the display 120 from the front or back.

As an example, the covering can be provided in the form of a transparent film. The bezel can cover the front or back of the display 120 and serve to protect the display 120 from impact and contamination. In the present embodiment, panels 122 and 124 are shown as being arranged on the front and back of display 120 by way of example. The fairings 122 and 124 can dress the front and back of the display 120 and protect the display 120 .

The cover 122 (hereinafter referred to as “front cover”) configured to cover a front side of the display 120 can protect the display 120 from the front side of the exhaust device 120 . The front panel 122 can protect the display 120 so that the display 120 is not contaminated by polluted air generated from the front of the exhaust device 100, impurities from a cooking appliance, and so on. Likewise, the front cover 122 can protect the display 120 from physical impacts exerted by a cooking appliance and the like.

Also, the shroud 124 (hereinafter referred to as “back shroud”) may be disposed at the rear of the display 120 and may shroud the rear of the display 120 between the display 120 and the exhaust flow path 110a. The back cover 124 can protect the display 120 so that the display 120 is not polluted due to the polluted air etc. flowing through the exhaust air flow path 110a.

As another example, as in 6 shown, a display 120a may be located on the back 113 of the body.

In this case, the display 120a can output an image from the rear of the main body 110 toward the front. Also, the front body 111 located in front of the display 120a may be formed of a transparent material to allow an image output from the display 120a to be seen clearly from the front of the front body 111.

The cover 126 can protect the display 120a so that the display 120a is not contaminated due to the polluted air etc. flowing through the exhaust air flow path 110a.

[Detailed structure of the display]

7 12 is a view schematically showing a structure of the exhaust device according to an embodiment of the present invention.

With reference to 2 and 7 For example, the display 120 can be provided in a form that includes a waveguide display. The display 120 may be provided to implement light transmitted from the stand alone projector 130 through the waveguide display in an image.

The waveguide display is a display that uses optical technology in which light is captured in a transparent thin optical medium and propagated and transmitted to provide an image.

A property of light is that when it is incident from a dense medium onto a thinner medium, it is totally reflected without being refracted beyond a specific angle of incidence. Using this property, light can be guided in the medium without its own reflective coating. An optical waveguide system utilizing total internal reflection is usually composed of a thin medium having a thickness of a few millimeters or less. In such an optical waveguide system, a coupler configured to input or output image light to or from a medium may be additionally arranged.

The display 120 using the optical waveguide system may include an incoupler 121, a waveguide 123, and an outcoupler array.

The projector 130 can be arranged in front of the incoupler 121 . Light transmitted from the projector 130 may be collimated into parallel light and introduced into a medium of the display 120 via the incoupler 121 .

The light introduced into the medium of the display 120 via the incoupler 121 can travel through the waveguide 123 in this way. The incoupler 121 and the waveguide 123 can be connected in the lateral direction. The waveguide 121 connected to the incoupler 121 in this way can totally reflect the light introduced through the incoupler 121 and transmit the light in the lateral direction.

According to the present embodiment, the incoupler 121 may be arranged on one side of the waveguide 123 in the lateral direction, and the outcoupler array may be arranged on the other side of the waveguide 123 in the lateral direction. The outcoupler array can be connected to the waveguide 123 in the lateral direction. That is, the incoupler 121, the waveguide 123, and the outcoupler array can be continuously arranged in the lateral direction.

The light that is totally reflected by the waveguide 123 and travels in the lateral direction can be output via the outcoupler array. Here the outcoupler array can be designed so that only a portion of the total guided light exits the medium. Additionally, the remaining guided light trapped in the medium can be retransmitted by total internal reflection and then a portion of the remaining guided light can be output again.

By repeating such a process in the outcoupler array, an image can be provided in a greatly expanded area compared to a viewable area in a conventional display.

For this purpose, the outcoupler array can have several outcouplers 125 . In the outcoupler array, the multiple outcouplers 125 may be continuously arranged in the lateral direction.

Accordingly, only a portion of the light that is totally reflected from the waveguide 123 and travels in the lateral direction can exit through the outcoupler 125 closest to the incoupler 121, and after the remaining guided light is totally reflected and moves to the side again moved in the same direction, a portion of the remaining guided light can be output again via another outcoupler 125. By repeating the above process over the multiple outcouplers 125 continuously arranged in the lateral direction, an image can be output through the display 120 of the present embodiment. According to the present embodiment, the projector 130 may be arranged in front of the incoupler 121 and may be arranged between the incoupler 121 and the cooking surfaces 23a and 23b.

That is, the projector 130 can be arranged between the incoupler 121 and the cooking surfaces 23a and 23b in the front and rear direction and arranged at a position adjacent to the incoupler 121 in the lateral direction. Between the display 120 and the cooking surfaces 23a and 23b, the projector 130 can transmit light toward the display 120 for image output. The projector 130 can be arranged at a position closer to the incoupler 121 in the entire area of the display 120 and can transmit light toward the incoupler 121 .

In particular, the projector 130 can be arranged at a position closer to the incoupler 121 than the cooking surfaces 23a and 23b. That is, the projector 130 may be located between the cooking surfaces 23a and 23b and the incoupler 121 and located closer to the incoupler 121 than to the cooking surfaces 23a and 23b.

That is, the projector 130 can transmit light for image output while being located at a position very close to the display 120, and the display 120 can efficiently output an image using the light transmitted from the projector 130 in this way .

As described above, by outputting an image using the waveguide display, the display 120 of the present embodiment can provide an image in a more expanded area compared to a viewable area in a conventional display.

The display 120 of the present embodiment can efficiently output the light transmitted from the projector 130 on the entire display 120 even in a state where a length between the display 120 and the projector 130 is much shorter than a length of the display in the lateral direction is.

This is because the display 120 of the present embodiment is provided in the form to which a waveguide display is applied. Image output through the display 120 can be sufficiently performed efficiently even in a state where the projector 130 is installed in a narrow space between the cooking surfaces 23a and 23b and the incoupler 121 and at a position closer to the incoupler 121 than the cooking surfaces 23a and 23b is installed.

That is, by allowing an image to be implemented on the display 120 using the projector 130 installed in a narrow space between the exhaust device 100 and a heater 20, the exhaust device 100 of the present embodiment can effectively provide an image while suppressing an increase in the overall size of the exhaust device and the cooking apparatus 100 comprising the same.

Also, the incoupler 121 may be arranged at a position closer to a side end portion of the main body 110 than to a side center of the main body 110 . The projector 130 arranged in front of the incoupler 130 may be arranged at a position closer to the lateral end portion of the main body 110 than the lateral center of the main body 110 like the incoupler 121 . Also, compared to the cooking surfaces 23a and 23b, the incoupler 121 and the projector 130 can be arranged at positions farther from the lateral center of the main body 110 in the lateral direction. The incoupler 121 and the projector 130 may be arranged in an area between the rightmost cooking surface 23b and a right end portion of the main body 110, for example.

That is, the incoupler 121 and the projector 130 may be arranged at a staggered position in the lateral direction.

Due to the characteristic of the waveguide display to transmit incident light through the incoupler 121 in the lateral direction and output an image, the incoupler 121 is inevitably arranged at a position offset in the lateral direction in the display 120 . Otherwise, an image can be output only on a part of the main body 110, and it is difficult to output an image on the entire surface of the main body 110.

Also, when the incoupler 121 is arranged at a position offset in the lateral direction as described above, the projector 130 that transmits the light toward the incoupler 721 is inevitably like the incoupler 121 at one in the lateral direction offset position arranged.

Also, the incoupler 121 may be arranged at a position closer to the intake opening 112 than at the lateral center of the main body 110 is located. Also, the projector 130 may be disposed at a position closer to the suction port 112 than the lateral center of the main body 110 like the incoupler 121 , and disposed below the suction port 112 .

Since the incoupler 121 and the projector 130 are disposed at such positions, light transmitted from the projector 130 can be introduced into the incoupler 121 without being affected by the polluted air sucked into the suction port 112 .

According to the present embodiment, when polluted air generated from the cooking device is sucked into the suction port 112, the polluted air does not move below the suction port 112. This is because a height of a cooking device is usually higher than a height of the bottom end of the intake port 112 is.

Therefore, when the incoupler 121 and the projector 130 are arranged at the positions described above, light transmitted from the projector 130 can travel toward the incoupler 121 across an area where no polluted air exists.

That is, by ensuring that the propagation of light transmitted from the projector 130 is not disturbed by polluted air, the exhaust device 100 of the present embodiment can improve the quality and visibility of an image output via the display 120 effectively.

[Exhaust Operation of Exhaust Device]

8th until 10 12 are views showing operation examples of the exhaust device according to an embodiment of the present invention.

With reference to 4 until 8th For example, each of the suction ports 112 arranged at a lateral position of the exhaust device 100 may be provided to be opened and closed separately.

An opening/closing component 160 for opening/closing the intake port 12 may be provided on the exhaust device 100 . The opening/closing component 160 may include a plurality of opening/closing members configured to open/close each of the suction ports 112 .

As an example, the opening/closing member may be arranged at the suction port 112 and directly open/close the suction port 112 .

As another example, the opening/closing member may be arranged at a lower end of the exhaust air flow path 110a or arranged between the lower end of the exhaust air flow path 110a and the suction port 112 . The opening/closing member can open/close the exhaust air flow path 110a to indirectly open/close the suction port 112 . In this case, the exhaust air flow path 110a may preferably be divided into a portion connected only to the suction port 112 located on one side in the lateral direction and a portion connected only to the suction port 112 located at the other side in the lateral direction.

Furthermore, the opening/closing component 116 may further include an opening/closing driving component configured to generate a force required for the opening/closing operation of the opening/closing member. As an example, the opening/closing driving component may be provided in a form having a plurality of driving motors to operate each opening/closing member separately.

Meanwhile, the cooking device of the present embodiment may further include a detection component 170 . The detection component 170 can detect positions of the cooking surfaces 23 a and 23 b on which a cooking device is placed, out of the plurality of cooking surfaces 23 a and 23 b provided on the heating device 20 . That is, the detection component 170 can detect the cooking surfaces 23a and 23b of a cooking device arranged thereon out of the plurality of cooking surfaces 23a and 23b.

As an example, the sensing component 170 may be provided in a form comprising a load cell, a proximity sensor, a camera, or any other sensor or visual inspection algorithm that can identify a positional dimension of the cooking device. In this case, a proximity sensor or a load cell can be arranged for each of the cooking surfaces 23a and 23b, and each proximity sensor can detect whether or not a cooking appliance is present.

As another example, the detection component 170 may be provided in a form that detects whether or not a heating component disposed in each of the cooking surfaces 23a and 23b is in operation. In this case, without that an independent sensor has to be installed in the cooking surfaces 23a and 23b, a control signal from a control unit 180 arranged to control the operation of the heating component can be used as information to identify whether the heating component is in operation or not.

According to the present embodiment, each of the suction ports 112 can be opened/closed independently, and the opening/closing of each suction port 112 can be controlled based on a result controlled by the detection component 170 .

For example, when only any one of the plurality of heating components arranged in a lateral direction operates or a cooking device is placed only on any one of the heating components, from the pair of suction ports 112 arranged in the lateral direction only any one of the suction openings 112 which is closer to the heating component in operation or the heating component on which the cooking device is placed may be opened.

As an example, as in 8th shown when only a heating component of the cooking surface 23a (hereinafter referred to as a “left cooking surface”) arranged to be offset to the left side operates or a cooking device arranged only on the left cooking surface 23a, For example, only one suction port 112 (hereinafter referred to as “left suction port”) located on the left side out of the pair of suction ports 112 may be opened.

When only the left suction port 112 is opened as described above, suction of polluted air generated from the cooking apparatus can be performed only through the left suction port 112.

As another example, as in 9 shown when only a heating component of the cooking surface 23b (hereinafter referred to as a “right cooking surface”) arranged to be offset to the right operates or a cooking device arranged only on the right cooking surface 23a only one suction port 112 (hereinafter referred to as “right suction port”) located on the right side out of the pair of suction ports 112 may be opened. When only the right suction port 112 is opened as described above, suction of polluted air generated from the cooking apparatus can be performed only through the right suction port 112.

When the opening/closing of the suction ports 112 is performed as described above, the suction of the polluted air is performed through the suction port 112 which is closest to a point where the polluted air is generated. Thus, the efficiency of collecting the polluted air can be increased very effectively.

Also, when the opening/closing of the suction ports 112 is performed as described above, only the suction port 112 near a point where the polluted air is generated is opened and the other suction port 112 is closed. That is, as large as a cross-sectional area occupied by the closed suction port 112, a cross-sectional area on which a suction force generated by an exhaust device 100 acts is reduced, and thus the suction air acting via the open suction port 112 can be increased very effectively.

Accordingly, since a distance between a point where suction occurs and a point where polluted air is generated is reduced, and at the same time, the suction force of the exhaust device 100 is also increased, the polluted air collection performance of the exhaust device 100 can also be improved be improved very effectively.

Also, when the opening/closing of the suction ports 112 is performed as described above, and accordingly the suction of polluted air is performed via the suction port 112 closest to the point where the polluted air is generated, occurrence of contact between the front of the main body 110 and the polluted air can be substantially reduced.

That is, polluted air generated from a cooking device located at a position shifted to the left (hereinafter referred to as “left cooking device”) is sucked into the left suction port 112 located on the left side of the exhaust device 100, and polluted air generated from a cooking device located at a position shifted to the right (hereinafter referred to as “right cooking device”) is sucked into the right suction port 112 located on the right side of the exhaust device 100 . In this way, polluted air generated from the cooking apparatus can be sucked into the suction ports 112 without passing through the center of the main body 110 in the lateral direction while contact with the main body 110 is minimized.

As yet another example, as in 10 As shown, when the heating components on both the left and right sides operate or a cooking device is placed on the heating components on both the left and right sides, the suction ports 112 on both sides can be opened.

When the suction ports 112 on both sides are opened as described above, suction of polluted air generated from a cooking apparatus can be performed via the suction ports 112 arranged on both sides. In the above state, polluted air generated from a front side of the exhaust device 100 may be divided to both sides, move backward, and then be collected from both sides of the exhaust device 100 .

[Image output operation of exhaust device]

11 until 13 12 are views showing image output states of the display according to an embodiment of the present invention.

With reference to 4 and 11 For example, the display 120 can be divided into multiple output areas A and B in the lateral direction. The display 120 may be provided to output an image on at least one selected from the plurality of output faces A and B.

The following describes the operation of the display 120 using an example in which the display 120 is divided into two output areas A and B. FIG. According to the present embodiment, the display 120 can output an image on at least any one of the two output surfaces A and B based on a result detected by the detection component 170 .

For example, when only one of the plurality of heating components arranged in the lateral direction operates or a cooking device is arranged only on any one of the heating components, the display 120 can output an image on one of the output surfaces A and B , which does not overlap in the fore and aft direction with the operating heating component or the cooking surfaces 23a and 23b having a cooking device placed thereon.

As an example, as in 11 shown, when none of the heating components are operating or no cooking device is placed on any of the heating components, the display 120 can output an image on both of the two output surfaces A and B.

In this case, since there is no obstacle blocking the view of the display 120 from the front of the display 120, image outputs on all of the output faces A and B can be displayed efficiently on the front.

As another example, as in 12 As shown, when only the heating component of the right cooking surface 23b is in operation or a cooking device is placed only on the right cooking surface 23b and is offset to the right, the display 120 can only output an image on the output surface A (hereinafter referred to as a "left Output area"), which is arranged on the left side from the two output areas A and B.

That is, an image is not output on the output surface B (hereinafter referred to as “right output surface”) that is likely to be blocked by a cooking device or has a view that is blocked by polluted air generated by the cooking device, and a Image is output only on the left output face A, which is not obstructed by the cooking device and is not so badly affected by the polluted air.

Yet another example, as in 13 shown, when only the heating component of the left cooking surface 23a is in operation or a cooking device is placed only on the left cooking surface 23a, the display 120 can only output an image on the right output surface B, which is on the right side of the two output surfaces A and B is arranged.

That is, an image is not output on the left output face A which is very likely to be obstructed by a cooking appliance or has a view obstructed by polluted air generated by the cooking appliance, and an image is output only on the right output face B emitted that is not obstructed by the cooking apparatus and is not as severely affected by the polluted air.

When an image is output on only one of the output surfaces as described above, an image cannot be output on an output surface that is likely to be obstructed by a cooking appliance, or has a view obstructed by polluted air generated by the cooking appliance, and an image can only be output on an output surface that is clearly visible to a user.

[Actions and effects of the exhaust device]

Actions and effects of the exhaust device according to the present invention are described below embodiment with reference to FIG 4 and 12 described.

In the exhaust device 100 of the present embodiment, the suction port 112 may be arranged at each of both side portions of the main body 110, and the display 120 may have the plurality of discharge surfaces A and B arranged in the lateral direction.

According to the present embodiment, the suction ports 112 are arranged at both side parts of the main body 110 without being arranged at the lower part or the upper part of the main body 110 .

In a case where the suction ports 112 are arranged at the lower portion of the main body 110, there arises a problem that a distance between a point where suction occurs and polluted air increases with an increase in the height of the cooker . If the distance between the point where suction occurs and the polluted air increases in this way, the polluted air collecting performance of the exhaust device 100 is inevitably deteriorated.

Of course, such a problem may also occur when the suction ports 112 are arranged at the upper portion or both side portions of the main body 110. However, an increase in distance relative to an increase in height of the cooker is greatest when the suction ports 112 are located at the lower portion of the main body 110 .

Also, in the case where the suction ports 112 are located at the lower portion of the main body 110 , polluted air generated from a cooking device moves downward and is sucked into the suction ports 112 . Assuming that the height of the cooking apparatus is similar to the height of the main body 110, polluted air generated from the cooking apparatus moves downward from an upper end side of the main body 110 and moves toward the suction ports 112.

In this process, contact inevitably occurs in a very large area between the polluted air and the main body 110, and thus a problem in which a degree of pollution of the front side of the main body 110 is increased may occur.

Also, as described above, the flow of contaminated air may serve to contaminate the front of the display 120 or obstruct the view of the display 120 from the front and thus become a factor in reducing the visibility of an image output by the display 120.

In a case where the suction ports 112 are disposed at the upper portion of the main body 110 , polluted air generated from a cooking device may be moved upward and sucked into the suction ports 112 . That is, in a case where the height of the cooking apparatus is lower than the height of the main body 110, polluted air generated from the cooking apparatus moves up to the upper portion of the main body 110 and moves toward the suction ports 112.

Even in this case, the degree of pollution of the front side of the main body 110 is increased due to the flow of the polluted air, and a problem that visibility of an image output through the display 120 is reduced may occur.

In view of such aspects, the suction ports 112 are arranged on both sides of the main body 110 in the present embodiment.

When the suction ports 112 are disposed on both side portions of the main body 110 as described above, polluted air generated from a cooking apparatus can move to the suction port 112 near a source of the polluted air.

i.e. contaminated air produced by a right cooking appliance may move toward the right intake port 112 and may be introduced into the intake ports 112, and contaminated air produced by a left cooking appliance may travel toward the left intake port 112 and into that intake port 112 to be initiated.

When the flow of the polluted air occurs as described above, the polluted air can be sucked into the exhaust device 100 while the contact with the front of the main body 110 is minimized.

Also, since collection of polluted air is performed as described above, an occurrence of a situation where the polluted air blocks the view of the exhaust device 100, particularly the display 120 from the front, can be greatly reduced.

In this way, not only is it easy to keep the outside of the exhaust device 100 clean, the quality and visibility of an image is improved Output from the display 120 can be effectively enhanced.

Also, the display 120 of the present embodiment cannot output an image over either of the output faces A and B that are likely to be blocked by a cooking appliance or have a view blocked by polluted air generated by the cooking appliance, and can output an image only over the others one of the output surfaces A and B which is not obstructed by the cooking apparatus and is not so badly affected by the polluted air.

For example, when the cooking device is placed only on a heating component of the right cooking surface 23b, the display 120 can output an image only on the left output surface A out of the two output surfaces A and B.

Here, of the pair of suction ports 112 , only the right suction port 112 located on the right side can be opened, and suction of polluted air generated from the cooking apparatus can be performed only through the right suction port 112 .

Accordingly, polluted air moves from the cooking device located in the right cooking surface 23b toward the right suction port 112 located further to the right of the cooking device. That is, the polluted air generated by the cooking device disposed on the right cooking surface 23b can flow toward the right suction port 112 immediately without flowing over the left discharge surface A at the front.

As a result, an image output of the display 120 becomes visible to the user in a state where the view of the image is not obstructed by either the polluted air or the cooking appliance. In this way, the visibility of the image output by the display 120 can be improved very effectively.

That is, by reducing a distance between a point where the suction occurs and the polluted air, an effect of providing a further improved polluted air collection performance can be provided, and at the same time, an effect of improving the visibility of the image output can be provided provided by the display 120 by preventing the view of the image output of the display 120 from being obstructed by the cooking appliance or polluted air.

As described above, the exhaust device 100 of the present embodiment can simultaneously provide a function of collecting and removing pollutants and a function of displaying an image, and by including methods such as adjusting a position where polluted air is sucked or adjusting a position where an image is output are used, visibility in the image output via the display 120 can be effectively improved.

Also, by minimizing the contact between the polluted air and the front side of the main body 110 and sucking the polluted air from both sides in the lateral direction, the exhaust device 100 of the present embodiment can simultaneously achieve an effect of keeping the outside of the exhaust device 100 clean and an effect of Provide improvement in the quality and visibility of the image output by the display 120.

By allowing an image output area to be changed according to the position of a cooking device, the exhaust device 100 of the present embodiment can effectively improve the visibility of an image output via the display 120 .

In addition, the exhaust device 100 of the present embodiment can simultaneously provide an effect of providing an improved collection performance of polluted air and an effect of improving the visibility of an image output by the display 120.

According to an exhaust air device and a cooking device having the same, a function of collecting and removing impurities and a function of displaying an image can be provided at the same time and by comprehensively using methods such as adjusting a position where polluted air is sucked or that Setting a position where an image is output are used, visibility of an image output via the display can be effectively improved.

Also, by minimizing contact between the polluted air and a front side of the main body and sucking the polluted air from both sides in the lateral direction, the present invention can simultaneously have an effect of keeping an outside of an exhaust device clean and an effect of improving quality and visibility in the image output provided by the display.

By allowing an image output surface to be changed according to the position of a cooking device, the present invention can be also effectively improve the visibility of an image output through the display.

Also, the present invention can simultaneously provide an effect of providing an improved collection performance of polluted air and an effect of improving the visibility of an image output through the display.

Also, by implementing an image on a display using a projector installed in a narrow space between the exhaust device and a heating device, the present invention can effectively provide the image while an increase in the overall size of the exhaust device and the cooking apparatus comprising the same is prevented.

Furthermore, by ensuring that the propagation of light transmitted from the projector is not disturbed by polluted air, the present invention can effectively improve the quality and visibility of an image output via the display.
