(Overall Configuration of Exhaust Device for Cookware)
FIG. 1 is a perspective view of an exhaust device for cooking utensils according to Embodiment 1. FIG. FIG. 2 is a front view of the cooking utensil exhaust device according to Embodiment 1. FIG. FIG. 3 is a side view of the cooking utensil exhaust device according to Embodiment 1. FIG.

As shown in FIG. 1, the cooking utensil exhaust device 100 according to the present embodiment includes a housing 120 forming a cooking chamber 110 having an opening 105, and an upper portion of the housing 120 that is installed in the cooking chamber 110 to It is characterized by having an exhaust part 130 for exhausting odors and an exhaust flow adjustment plate 140 attached to the housing 120 so as to be openable and closable so as to block a part of the upper side of the opening 105 .

As shown in FIGS. 1 to 3, the housing 120 has a base 125 that supports the cooking chamber 110 at its lower portion. Cooking utensils (not shown) are stored in the cooking chamber 110 above the pedestal 125, and the cook uses the cooking utensils. The cooking chamber 110 is formed so as to be surrounded from three directions by left and right side panels 115 and 116 and a rear panel 117 of the housing 120 . The side panels 115 and 116 and the rear panel 117 are attached without a gap so as to ensure airtightness. An opening 105 is formed on the front side of the cooking chamber 110 for the cook to cook.

The upper part of the housing 120 serves as an exhaust part 130 for exhausting oily smoke from the cooking chamber 110 . The exhaust unit 130 sucks oily smoke and odors from the upper surface of the cooking chamber 110, removes oil, smoke, and odors with a filter, and exhausts the purified exhaust air from the rear side exhaust port 139 provided on the top surface of the housing 120. , through a duct (not shown) to the outside. The detailed configuration and action of exhaust section 130 will be described later.

An exhaust flow adjustment plate 140 is attached to the lower side of the exhaust hole 135 so as to be able to open and close so as to block a part of the opening 105 . The exhaust flow adjustment plate 140 can open toward the front side of the housing 120 as indicated by the arrow in FIG. The exhaust flow adjusting plate 140 is closed except when cleaning.

The exhaust flow adjustment plate 140 has the function of narrowing the opening area of the opening 105 to increase the wind speed of the air sucked in from the opening 105, the function of guiding the air sucked in from the opening 105 to the lower surface of the exhaust unit 130 without stagnation, and the exhaust flow adjusting plate 140 having the function of It also has the function of preventing the air that has risen to the lower surface of the portion 130 from leaking into the room.

Since the exhaust flow adjustment plate 140 has these functions, the air sucked from the opening 105 rises without stagnation. Therefore, oily smoke and odors in the cooking chamber 110 are efficiently guided to the exhaust section 130, and heat transfer to the housing 120 can be reduced.

In addition, since oily smoke generated from the cooked food does not reach the cook's face, the safety of the cook can be ensured and the cooking work can be carried out comfortably. Furthermore, the oily smoke in the cooking chamber 110 is efficiently guided to the exhaust part 130, so the oily smoke collection rate is improved. Therefore, the energy saving of the exhaust part 130 can also be achieved.

In addition, since the exhaust flow adjustment plate 140 is provided on the front side of the upper part of the housing 120, in other words, on the front side of the exhaust section 130, there is an additional effect that noise such as fan noise of the exhaust section 130 can be blocked. can also be expected. The detailed configuration and action of the exhaust flow adjusting plate 140 will be described later.
(Structure of exhaust section)
FIG. 4 is a cross-sectional view taken along line AA of the cooking utensil exhaust device 100 shown in FIG. FIG. 5 is a diagram showing an exhaust passage formed around the straightening plate 138 by the inner panel 133 of the exhaust section 130 and the straightening plate 138 shown in FIG.

The exhaust part 130 has a fan 132 for sucking oily smoke and odors from the cooking chamber 110 and discharging them through an exhaust port 139 . Between the fan 132 and the cooking chamber 110 (see FIG. 2), the housing 120 is inclined from the front side toward the rear panel 117 (inclined downward from left to right in the drawing), and the lower part of the exhaust part 130 is An overall covering inner face panel 133 is attached. Although FIG. 4 illustrates the case where the inner panel 133 is inclined, the present invention is not limited to this, and the inner panel 133 may be provided horizontally. Further, in this case, the rectifying plate 138 may be provided inclined, or may be provided horizontally. A circular intake port 134 is opened in the central portion of the inner panel 133 . A disk 136 that rotates at high speed simultaneously with the fan 132 during exhaust operation is provided on the fan 132 side of the intake port 134 . The disk 136 has a filter function, and blows off the oil content of oil smoke sucked from the intake port 134 toward the oil guard 137 by centrifugal force.

The filter function is not limited to the disk 136 that rotates at high speed simultaneously with the fan 132 during the exhaust operation, and may be a filter that does not rotate during the exhaust operation.

In addition, a rectifying plate 138 is arranged on the inner panel 133 to form an exhaust flow path for oily smoke and odor in the outer peripheral portion of the inner panel 133 in a closed state, which is rotatably attached to one end of the inner panel 133 as a fulcrum. It is The rectifying plate 138 is arranged so as to cover the intake port 134 opened in the center of the inner panel 133 and to form a gap between the inner panel 133 and the rectifying plate 138 . The plate surface of the straightening plate 138 is not parallel to the plate surface of the inner panel 133, and the gap between the plate surface of the straightening plate 138 on the side of the exhaust flow adjusting plate 140 and the inner surface panel 133 is the rear surface. It is arranged to be inclined with respect to the inner panel 133 so as to be wider than the interval between the plate surface of the current plate 138 on the panel 117 side and the inner panel 133 . Therefore, by closing the rectifying plate 138, the flow velocity of oily smoke and odor in the cooking chamber 110 (see FIG. 2) is increased, and a flow path is formed in which the smoke flows without stagnation. It should be noted that the current plate 138 can be opened in the direction of the arrow in FIG. 4 (downward in the drawing). It should be noted that the current plate 138 has a substantially plate shape, and the plate shape may have a bent portion or a curved portion. In addition, the shape of the inner panel 133 is not limited to a shape recessed toward the downstream side, and may be flat without a recess.

An exhaust flow adjustment plate 140 is attached to the lower side of the exhaust hole 135 so as to be openable and closable. The exhaust flow adjustment plate 140 can be opened in the direction of the arrow in FIG. 4 (to the left in the drawing). Opening the exhaust flow adjustment plate 140 facilitates cleaning of the inner surface of the exhaust flow adjustment plate 140 and the outer surface of the current plate 138 . Further, when the straightening plate 138 is opened, cleaning of the inner surface of the inner panel 133, the disk 136, and the inner surface of the straightening plate 138 becomes easy.

FIG. 5 is a diagram showing an exhaust passage formed around the straightening plate 138 by the inner panel 133 of the exhaust section 130 and the straightening plate 138 shown in FIG. FIG. 5 is a view of the lower portion of the exhaust section 130 viewed from the direction of the white arrow in FIG. The direction of the white arrow is the direction perpendicular to the surface of the inner panel 133 .

As shown in FIG. 5 , the current plate 138 is arranged so that the channel on the front side of the housing 120 is larger than the channel on the back side. As a result, the amount of air taken in from the front side of the cooking chamber 110 becomes larger than the amount of air taken in from the rear side.

Specifically, as shown in FIG. 5, the width of the exhaust flow path formed by the inner panel 133 and the current plate 138 in the direction of the side panels 115 and 116 of the housing 120 is c. In addition, the width of the exhaust flow path formed by the inner panel 133 and the current plate 138 in the direction of the exhaust flow adjustment plate 140 is a. Further, the width of the exhaust flow path formed by the inner panel 133 and the current plate 138 in the direction of the rear panel 117 of the housing 120 is b . The widths of these exhaust passages have a relationship of a>c>b.

If the dimensions of the exhaust flow path formed around the current plate 138 by the inner panel 133 and the current plate 138 are made uneven, the amount of oily smoke and odor flowing from the cooking chamber 110 into the housing 120 is can be adjusted for each direction.

In the case of FIG. 5, the amount of air flowing from the opening 105 (see FIG. 2) of the cooking chamber 110 to the exhaust flow adjustment plate 140 side is the largest. Also, the amount of air flowing toward the side panels 115 and 116 of the housing 120 is the next largest, and the amount of air flowing toward the rear panel 117 of the housing 120 is the smallest. Therefore, it is possible to effectively prevent the oily smoke generated from the cooked food from coming into contact with the cook's face. In addition, the heat generated in the cooking chamber 110 can be prevented from being directly transmitted to the side panels 115 and 116, ensuring the safety of the cook.

Note that the exhaust unit 130 can also be configured as follows. For example, when an opening/closing sensor for detecting opening/closing of the rectifying plate 138 is provided in the exhaust unit 130 or the inner panel 133, and the opening/closing sensor detects that the rectifying plate 138 is opened while the fan 132 and/or the disk 136 is rotating. may turn off fan 132 and/or disk 136 . This can prevent injury from accidentally touching fan 132 and/or disk 136 while fan 132 and/or disk 1366 are rotating.

Further, an opening/closing sensor for detecting opening/closing of the exhaust flow adjusting plate 140 is provided on the exhaust unit 130 or the side panels 115 and 116, and the opening/closing sensor opens the exhaust flow adjusting plate 140 while the fan 132 and/or the disk 136 is rotating. If so, the fan 132 and/or disk 136 are stopped. This can prevent injury from accidentally touching the fan 132 and/or the disk 136 while the fan 132 and/or the disk 136 are rotating.
(Structure of Exhaust Flow Adjusting Plate 140)
6A is an enlarged view of a portion D of the exhaust flow adjusting plate shown in FIG. 4. FIG. FIG. 6B is a diagram showing another aspect of the exhaust flow adjusting plate shown in FIG. 6A.

The exhaust flow adjusting plate 140 has a heat insulating layer so that the heat of oil smoke or odor from the cooking chamber 110 sucked by the exhaust part 130 does not heat the outer surface of the exhaust flow adjusting plate 140 .

A heat insulating layer is formed by a structure as shown in FIG. 6A or FIG. 6B. As shown in FIG. 6A, the exhaust flow adjustment plate 140 is formed of two panels, a front panel 140a and a rear panel 140b, and an air layer 140c is formed as a heat insulating layer between the front panel 140a and the rear panel 140b. ing. The air layer 140c prevents the heat of greasy smoke and odor in the cooking chamber 110 from being transmitted from the rear panel 140b to the front panel 140a.

The air layer 140c of the exhaust flow adjusting plate 140 prevents the heat in the cooking chamber 110 from being transferred to the interior of the cooking chamber 110, thereby preventing the temperature in the room from rising, and preventing the cook from accidentally touching the outer surface of the exhaust flow adjusting plate 140. Even if you do, you will not get burned. Moreover, since the air layer 140c also functions as a sound insulation layer and a sound absorption layer, noise from the exhaust section 130 can be blocked.

Also, as shown in FIG. 6B, the exhaust flow control plate 140 is formed of two panels, a front panel 140a and a rear panel 140b, and a heat insulating material forming a heat insulating layer between the front panel 140a and the rear panel 140b. 140d is filled. The heat insulating material 140d prevents the heat of oil smoke and odor in the cooking chamber 110 from being transmitted from the rear panel 140b to the front panel 140a. As the heat insulating material 140d, it is preferable to use a material having a greater heat insulating effect.

Since the exhaust flow adjusting plate 140 has a heat insulating layer formed by the heat insulating material 140d, the heat in the cooking chamber 110 is prevented from being transmitted into the room, thereby preventing the temperature in the room from rising, and preventing the cook from accidentally adjusting the exhaust flow. Even if you touch the outer surface of the plate 140, you will not get burned. Moreover, if a material having excellent sound insulation properties is employed as the heat insulating material 140d, the noise from the exhaust section 130 can be effectively blocked and absorbed.

6A and 6B illustrate the case of providing the air layer 140c and the case of filling the heat insulating material 140d, but the space between the front panel 140a and the rear panel 140b may be a vacuum structure. However, in this case, it is necessary to increase the strength of the front panel 140a and the rear panel 140b, or to provide a reinforcing material in the space between the front panel 140a and the rear panel 140b.

The longitudinal direction (horizontal (horizontal) direction in FIG. 2) of the exhaust flow adjusting plate 140 substantially matches the length of the opening 105 in the lateral direction, and is preferably laterally long.

As described above, the exhaust flow adjusting plate 140 has the function of narrowing the opening area of the opening 105 (see FIG. 2) to increase the wind speed of the air sucked in from the opening 105, and the function of smoothing the air sucked in from the opening 105. It also has a function of leading to the lower surface of the exhaust portion 130 . Therefore, the vertical and horizontal dimensions of the exhaust flow adjusting plate 140 are important.

The exhaust flow adjusting plate 140 blocks at least 20% or more of the opening 105 . As a result, oily smoke and odors in the cooking chamber 110 can be efficiently exhausted. Moreover, it is possible to suppress the heat in the cooking chamber 110 from propagating into the room. Also, noise from the exhaust part 130 can be suppressed. More preferably, the exhaust flow adjustment plate 140 blocks 30% or more and 70% or less of the opening 105 . According to this, since the cooking space can be secured while the effect is exhibited more effectively, cooking can be performed without opening and closing the exhaust flow adjusting plate 140 .

In addition, if the vertical dimension of the exhaust flow adjustment plate 140 is increased, the opening area of the opening 105 of the cooking chamber 110 is decreased, so that the collection rate of oily smoke and odor is improved. If the collection rate is improved, oily smoke and odors are less likely to leak from the cooking chamber 110, and the oily smoke and odors are sucked into the exhaust section 130 before they accumulate inside the housing 120, resulting in high heat insulation. On the other hand, if the vertical dimension of the exhaust flow adjusting plate 140 is too large, it becomes difficult for the cook to cook. For this reason, in the present embodiment, the exhaust flow adjustment plate 140 has a horizontally elongated shape whose longitudinal direction substantially matches the length of the opening 105 in the left-right direction.

Considering the workability of cooking, it is sufficient if the vertical opening dimension of the opening 105 can be secured at least about 30 cm. In other words, the height of the portion where the opening is not closed should be 30 cm or more. In this embodiment, this is expressed as 70% or less of the area of the opening 105 . In addition, in order to efficiently exhaust the oily smoke and odor in the cooking chamber 110 and suppress the noise from the exhaust part 130, the exhaust flow adjustment plate 140 must be 30% or more of the opening part 105. It is desirable to block the area of
(Configuration of opening/closing mechanism of exhaust flow adjustment plate 140)
7A to 7F are diagrams for explaining the opening and closing mechanism of the exhaust flow adjustment plate 140. FIG. As shown in these figures, the exhaust flow adjusting plate 140 is attached to the upper part of the housing 120 so as to be openable and closable by means of an opening/closing support 145 .

7A is a BB cross-sectional view of the cookware exhaust device 100 shown in FIG. 2, showing the exhaust flow adjusting plate 140 and the opening/closing support 145 when the exhaust flow adjusting plate 140 is closed. FIG. 7B is a perspective view showing a state in which the exhaust flow adjusting plate 140 is closed. FIG. 7C is a perspective view showing a state in which the exhaust flow adjusting plate 140 is opened to the first angle. FIG. 7D is a perspective view showing a state in which the exhaust flow adjusting plate 140 is opened at a second angle larger than the first angle. FIG. 7E is a diagram showing the exhaust flow adjustment plate 140 and the opening/closing support 145 when the exhaust flow adjustment plate 140 is opened in FIG. 7A. FIG. 7F is a perspective view showing a state in which the exhaust flow adjusting plate 140 is opened 90 degrees.

As shown in FIG. 7A, the exhaust flow adjustment plate 140 is supported by an opening/closing support portion 145 at the upper portion of the housing 120 so as to be freely opened and closed in the arrow direction. The opening/closing support portion 145 is provided at one side end portion of the exhaust flow adjustment plate 140 . Note that the opening/closing support portions 145 may be provided at both side end portions of the exhaust flow adjusting plate 140 (horizontal direction in the figure).

The opening/closing support portion 145 can be stored in a storage portion 147 provided on the side surface of the housing 120 as shown in FIGS. 7C, 7D, and 7F. The storage part 147 is a hollow space formed in the side panel 115 of the housing 120 and extending from the front end of the side panel 115. It is closed by the exhaust flow control plate 140 when 140 is closed. The hollow space of the side panel 115 is formed by making the side panel 115 into a two-layer structure. When the exhaust flow adjusting plate 140 is closed, the opening/closing support portion 145 is stored in the storage portion 147, so that the opening/closing support portion 145 can be prevented from being contaminated with oil. Further, the airtightness of the opening of the storage portion 147 is ensured by the plate surface of the exhaust flow adjustment plate 140, so that the storage portion 147 can be prevented from being contaminated with oil.

Specifically, as shown in FIG. 7A , when the exhaust flow adjustment plate 140 is closed, the opening/closing support portion 145 is folded and stored in the storage portion 147 provided on the side surface of the housing 120 . Further, as shown in FIG. 7B , the opening of the storage portion 147 is closed by the plate surface of the exhaust flow adjusting plate 140 .

As shown in FIGS. 7C to 7F, when the exhaust flow adjustment plate 140 is opened to the first angle, the second angle, and 90 degrees, the sliding portion 143 shown in FIG. 7A is rotatably attached to the fulcrum 141. Then, the support rod 142 and the slide portion 143 are exposed from the opening of the storage portion 147 .

In this way, the opening/closing support portion 145 of the exhaust flow adjusting plate 140 does not come into contact with oily smoke when the exhaust flow adjusting plate 140 is closed. When the exhaust flow adjustment plate 140 is closed, the opening/closing support 145 enters the hollow space created by the two-layer structure of the side panel 115 . Further, when the exhaust flow adjusting plate 140 is closed, the exhaust flow adjusting plate 140 covers the opening for accommodating the opening/closing support portion 145 . Therefore, the opening/closing support part 145 and the opening do not come into contact with oily smoke.

Therefore, oil is prevented from adhering to and sticking to the opening/closing support portion 145, and the exhaust flow adjustment plate 140 can be opened and closed smoothly. Also, even if oil adheres to the opening/closing support portion 145, the frequency of cleaning is less than if it were exposed.

Note that the opening/closing support may be, for example, a damper, a screw, an engagement by a nail, a roller catch, a magnet, or the like (configuration of the side panel 115).
FIG. 8 is a CC cross-sectional view of the cookware exhaust system 100 shown in FIG. 9A is an enlarged view of part E of side panel 115 of housing 120 shown in FIG. FIG. 9B is a diagram showing another aspect of the side panel 115 of the housing 120 shown in FIG. 9A. Note that the configuration of the side panel 116 is the same as the configuration of the side panel 115 .

The side panels 115 and 116 of the housing 120 forming the cooking chamber 110 have heat insulating layers so that the outer surfaces of the side panels 115 and 116 are not heated by the heat of the oily smoke or odor in the cooking chamber 110 .

A heat insulating layer is formed by a structure as shown in FIG. 9A or FIG. 9B. The side panel 115 is formed of two panels, an inner panel 115a and an outer panel 115b, and an air layer 115c is formed as a heat insulating layer between the inner panel 115a and the outer panel 115b. The air layer 115c prevents the heat of greasy smoke and odor in the cooking chamber 110 from being transferred from the inner panel 115a to the outer panel 115b.

Since the side panel 115 has the air layer 115c, even if the cook accidentally touches the outer surface of the side panel 115, he/she will not be burned. In addition, since the heat of the oily smoke and odor in the cooking chamber 110 is less likely to be transmitted to the outer panel 115b, the heat during cooking is less likely to affect the room temperature. Therefore, even when the room is kept cool by an air conditioner in summer, the temperature is less likely to be transmitted to the inside of the housing 120 . Therefore, it is possible to reduce the decrease in the temperature inside the housing 120 and solve the problem that it takes time for the temperature of the oil to rise.

Also, as shown in FIG. 9B, the side panel 115 is formed of two panels, an inner panel 115a and an outer panel 115b, and a heat insulating material 115d forming a heat insulating layer is provided between the inner panel 115a and the outer panel 115b. filled. The heat insulating material 115d prevents the heat of greasy smoke and odor in the cooking chamber 110 from being transferred from the inner panel 115a to the outer panel 115b. As the heat insulating material 115d, it is preferable to use a material having a greater heat insulating effect. In addition, if a material having excellent sound insulation properties is employed as the heat insulating material 115d, the cooking noise in the cooking chamber 110 can be effectively absorbed.

9A and 9B illustrate the case of providing the air layer 115c and the case of filling the heat insulating material 115d, the space between the inner panel 115a and the outer panel 115b may be a vacuum structure. However, in this case, it is necessary to increase the strength of the inner panel 115a and the outer panel 115b, or provide a reinforcing member in the space between the inner panel 115a and the outer panel 115b.

As described above, according to the cooking utensil exhaust device 100 according to the present embodiment, the exhaust flow adjustment plate 140 is provided on the front surface of the exhaust section 130 provided on the upper part of the housing 120, and the inner surface panel 133 is provided on the lower surface of the exhaust section 130. Since the rectifying plate 138 is provided, the air sucked from the opening 105 of the cooking chamber 110 can be efficiently exhausted. Therefore, the heat insulation of the cooking chamber 110 can be improved.

In addition, since the exhaust flow control plate 140 and the side panels 115 and 116 of the housing 120 are provided with heat insulating layers, the heat during cooking is difficult to transmit, and the safety of the cook can be ensured.
