Description

  The present invention relates to an exhaust device for cooking utensils.

  A cooking device may be installed on a floor in a store such as a convenience store, a supermarket, or a department store, and freshly cooked dishes may be provided (sold) to customers.

  When cooking in a store, it is required to ensure the safety of the cook and to prevent odors and the like generated during cooking from drifting in the store.

  In order to meet this requirement, in Patent Document 1, a lid that can be opened and closed by sliding up and down on the front surface of the cooking apparatus is provided, and the lid is closed during cooking to ensure the safety of the cooker and exhaust the stove. A cooking apparatus that efficiently collects the food is disclosed.

JP-A-6-74507

  However, in the conventional cooking apparatus, in order to ensure the safety of the cook and to efficiently exhaust, the lid must be opened and closed at the end of cooking. Opening and closing the lid during cooking is troublesome for the cook and increases the work load on the cook.

  Further, when the lid is closed, heat is easily generated in the casing of the cooking apparatus. Since the heat insulation of the housing is not so good, the housing is likely to become hot and it is difficult to ensure the safety of the cook.

  Then, this invention aims at provision of the exhaust apparatus for cooking appliances which can reduce a work burden of a chef, can ensure a chef's safety | security, and can exhaust efficiently.

  In order to achieve the above object, the present invention provides a casing that forms a cooking chamber having an opening, an exhaust that is installed in the upper portion of the casing and exhausts oily smoke and odors in the cooking chamber, and an upper portion of the opening. It is an exhaust apparatus for cooking appliances having an exhaust flow adjusting plate attached to the upper part of the housing so as to close the part.

  According to the present invention, since it is not necessary to open and close the lid one by one at the end of cooking, the work load on the cook can be reduced. Moreover, since the exhaust flow adjusting plate is attached so as to block a part of the upper portion of the opening, the oil smoke and odor in the cooking chamber can be efficiently exhausted. Furthermore, since heat is not generated in the cooking chamber by efficient exhaust, the casing and the exhaust flow adjusting plate are not easily heated, and the safety of the cook can be ensured.

[Embodiment 1]
(Overall configuration of cooking appliance exhaust system)
FIG. 1 is a perspective view of the cooking appliance exhaust device according to the first embodiment. FIG. 2 is a front view of the cooking appliance exhaust device according to the first embodiment. FIG. 3 is a side view of the cooking appliance exhaust device according to the first embodiment.

  As shown in FIG. 1, the cooking appliance exhaust device 100 according to the present embodiment includes a casing 120 that forms a cooking chamber 110 having an opening 105, and oil smoke in the cooking chamber 110 that is installed on the upper portion of the casing 120. It is characterized by having an exhaust part 130 for exhausting odor and an exhaust flow adjusting plate 140 attached to the casing 120 so as to be openable and closable so as to block a part of the upper side of the opening part 105.

  As shown in FIGS. 1 to 3, the lower part of the casing 120 is a pedestal 125 that supports the cooking chamber 110. A cooking utensil (not shown) is stored in the cooking chamber 110 at the top of the gantry 125, and the cook uses the cooking utensil to cook. The cooking chamber 110 is formed so as to be surrounded from three directions by the left and right side panels 115 and 116 and the back panel 117 of the housing 120. The side panels 115 and 116 and the back 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 so that the cook can cook.

  The upper part of the housing 120 is an exhaust part 130 for exhausting the oil smoke in the cooking chamber 110. The exhaust unit 130 sucks oil smoke and odor from the upper surface of the cooking chamber 110, removes oil, smoke, and odor by a filter, and exhausts purified air from a back side exhaust port 139 provided on the top surface of the housing 120. , It is discharged outside through a duct (not shown). The detailed configuration and operation of the exhaust unit 130 will be described later.

  An exhaust flow adjusting 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 adjusting plate 140 can be opened toward the front side of the housing 120 as indicated by an arrow in FIG. Exhaust flow adjustment plate 140 is closed except for cleaning.

  The exhaust flow adjusting plate 140 has a function of narrowing the opening area of the opening 105 to increase the wind speed of air sucked from the opening 105, a function of guiding the air sucked from the opening 105 to the lower surface of the exhaust part 130, and exhaust A function of preventing the air rising up to the lower surface of the portion 130 from leaking into the room.

  Since the exhaust flow adjusting plate 140 has these functions, the air sucked from the opening 105 rises without stagnation. For this reason, the oil smoke and odor in the cooking chamber 110 are efficiently guided to the exhaust part 130, and heat transfer to the housing 120 can be reduced.

  In addition, oil smoke generated from the food is not applied to the face of the cook, so the safety of the cook can be ensured and a comfortable cooking operation can be performed. Furthermore, since the oil smoke in the cooking chamber 110 is efficiently guided to the exhaust part 130, the collection rate of oil smoke is improved. Therefore, energy saving of the exhaust part 130 can also be achieved.

Further, since the exhaust flow adjusting plate 140 is provided on the front side of the upper portion of the casing 120, in other words, on the front side of the exhaust unit 130, an incidental effect that noise such as a fan sound of the exhaust unit 130 can be insulated. Can also be expected. The detailed configuration and operation of the exhaust flow adjusting plate 140 will be described later.
(Exhaust structure)
FIG. 4 is a cross-sectional view of the exhaust device 100 for cooking utensil shown in FIG. FIG. 5 is a view showing an exhaust passage formed by the inner surface panel 133 and the rectifying plate 138 of the exhaust unit 130 shown in FIG. 4 around the rectifying plate 138.

  The exhaust unit 130 includes a fan 132 for sucking oil smoke and odor from the cooking chamber 110 and discharging them to the 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 the left to the right in the drawing), and the lower portion of the exhaust unit 130 is An inner panel 133 that covers the entire surface is attached. Although FIG. 4 illustrates the case where the inner panel 133 is inclined, the present invention is not limited thereto, and the inner panel 133 may be provided horizontally. In this case, the current plate 138 may be provided in an inclined manner or may be provided horizontally. A circular air inlet 134 is opened at the center of the inner panel 133. A disk 136 that rotates at the same time as the fan 132 during exhaust operation is provided on the fan 132 side of the air inlet 134. The disk 136 has a filter function, and blows off oil components of the oil smoke sucked from the air inlet 134 toward the oil guard 137 by centrifugal force.

  The filter function is not limited to the disk 136 that rotates at the same time as 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 that forms an exhaust passage for oily smoke and odors on the outer peripheral portion of the inner panel 133 in a state where the inner panel 133 is pivotally attached and closed with one end of the inner panel 133 as a fulcrum is disposed on the inner panel 133. Has been. The rectifying plate 138 is disposed so as to cover the air inlet 134 opened at the center of the inner surface panel 133 and to form a gap between the inner surface panel 133 and the rectifying plate 138. In the rectifying plate 138, the plate surface of the rectifying plate 138 is not parallel to the plate surface of the inner surface panel 133, and the distance between the plate surface of the rectifying plate 138 on the exhaust flow adjusting plate 140 side and the inner surface panel 133 is the back surface. It is inclined with respect to the inner surface panel 133 so as to be wider than the distance between the plate surface of the current plate 138 on the panel 117 side and the inner surface panel 133. Therefore, by closing the rectifying plate 138, the flow rate of oil smoke and odor in the cooking chamber 110 (see FIG. 2) is increased, and a flow path that flows without stagnation is formed. The rectifying plate 138 can be opened in the direction of the arrow in FIG. Note that the rectifying plate 138 has a substantially plate shape, and the plate shape may have a bent portion or a curved portion. Moreover, the inner surface panel 133 is not limited to the shape recessed toward the downstream side, and may be planar without any recess.

  An exhaust flow adjusting plate 140 is attached to the lower side of the exhaust hole 135 so as to be freely opened and closed. The exhaust flow adjusting plate 140 can be opened in the direction of the arrow in FIG. When the exhaust flow adjusting plate 140 is opened, cleaning of the inner surface of the exhaust flow adjusting plate 140 and the outer surface of the rectifying plate 138 is facilitated. Further, when the current plate 138 is opened, cleaning of the inner surface of the inner surface panel 133, the disk 136, and the inner surface of the current plate 138 becomes easy.

  FIG. 5 is a view showing an exhaust passage formed by the inner surface panel 133 and the rectifying plate 138 of the exhaust unit 130 shown in FIG. 4 around the rectifying plate 138. FIG. 5 is a view of the lower part of the exhaust part 130 as seen from the direction of the white arrow in FIG. The white arrow direction is a direction orthogonal to the plate surface of the inner panel 133.

  As shown in FIG. 5, the rectifying plate 138 is arranged such that the flow path on the front side is larger than the flow path on the back side of the housing 120. Thereby, the amount of air sucked from the front side of the cooking chamber 110 becomes larger than the amount of air sucked from the rear side.

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

  If the size of the exhaust passage formed around the rectifying plate 138 is made uneven by the inner surface panel 133 and the rectifying plate 138, the amount of oil smoke and odor flowing from the cooking chamber 110 to the inside of the case 120 is reduced. It 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. In addition, the amount of air that flows to the side panels 115 and 116 side of the housing 120 is the next largest, and the amount of air that flows to the rear panel 117 side of the housing 120 is the smallest. For this reason, it can prevent effectively that the oily smoke which generate | occur | produced from the cooking thing covers a chef's face. In addition, it is possible to prevent the heat generated in the cooking chamber 110 from being directly transmitted to the side panels 115 and 116, thereby ensuring the safety of the cook.

  In addition, the exhaust part 130 can also be comprised as follows. For example, when an opening / closing sensor for detecting opening / closing of the rectifying plate 138 is provided in the exhaust part 130 or the inner panel 133 and the fan 132 or / and the disk 136 is rotating, the opening / closing sensor detects that the rectifying plate 138 is opened. The fan 132 or / and the disk 136 may be stopped. Thus, it is possible to prevent the fan 132 or / and the disk 1366 from accidentally touching the fan 132 or / and the disk 136 during the rotation.

Further, an opening / closing sensor for detecting opening / closing of the exhaust flow adjusting plate 140 is provided in the exhaust unit 130 or the side panels 115, 116, and the exhaust flow adjusting plate 140 is opened by the opening / closing sensor while the fan 132 or / and the disk 136 is rotating. If detected, the fan 132 and / or the disk 136 are stopped. Thus, it is possible to prevent the fan 132 or / and the disk 136 from accidentally touching the fan 132 or / and the disk 136 during the rotation.
(Configuration of exhaust flow adjusting plate 140)
6A is an enlarged view of a portion D of the exhaust flow adjusting plate shown in 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 outer surface of the exhaust flow adjusting plate 140 is not heated by the heat of oil smoke or odor from the cooking chamber 110 sucked by the exhaust unit 130.

  The heat insulating layer is formed by a structure as shown in FIG. 6A or 6B. As shown in FIG. 6A, the exhaust flow adjusting 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 oil smoke and odor heat from the cooking chamber 110 from being transmitted from the rear panel 140b to the front panel 140a.

  Since the exhaust flow adjusting plate 140 has the air layer 140c, the heat of the cooking chamber 110 is prevented from being transmitted to the room to prevent the indoor temperature from rising, and the cook accidentally touches the outer surface of the exhaust flow adjusting plate 140. If you do, you will not be burned. Moreover, since the air layer 140c functions also as a sound insulation layer and a sound absorption layer, the noise from the exhaust part 130 can also be blocked.

  Further, as shown in FIG. 6B, the exhaust flow adjusting plate 140 is formed of two panels, a front panel 140a and a rear panel 140b, and a heat insulating material that forms a heat insulating layer between the front panel 140a and the rear panel 140b. 140d is filled. The heat insulating material 140d prevents oil smoke and odor heat from 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 larger heat insulating effect.

  By having the heat insulation layer formed by the heat insulating material 140d in the exhaust flow adjusting plate 140, the heat of the cooking chamber 110 is prevented from being transmitted into the room, and the cook adjusts the exhaust flow by mistake. Even if the outer surface of the plate 140 is touched, there is no burn. In addition, if a material having excellent sound insulation is employed as the heat insulating material 140d, noise from the exhaust part 130 can also be effectively blocked and absorbed.

  6A and 6B illustrate the case where the air layer 140c is provided and the case where the heat insulating material 140d is filled, 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 exhaust flow adjusting plate 140 has a longitudinal direction (left and right (horizontal) direction in FIG. 2) that is substantially the same as the length of the opening 105 in the left and right direction, and is preferably horizontally long.

  As described above, the exhaust flow adjusting plate 140 narrows the opening area of the opening 105 (see FIG. 2) and increases the wind speed of the air sucked from the opening 105, and does not stagnate the air sucked from the opening 105. And a function of leading to the lower surface of the exhaust portion 130. For this reason, the dimensions of the exhaust flow adjusting plate 140 in the vertical and horizontal directions are important.

  The exhaust flow adjusting plate 140 closes at least 20% of the opening 105. Thereby, the oil smoke and odor in the cooking chamber 110 can be efficiently exhausted. Moreover, it can suppress that the heat in the cooking chamber 110 propagates indoors. Moreover, the noise from the exhaust part 130 can be suppressed. The exhaust flow adjusting plate 140 is more preferably in a state where 30% to 70% of the opening 105 is closed. According to this, since an effect is exhibited more and a cooking space can be secured, cooking can be performed without opening and closing the exhaust flow adjusting plate 140.

  Moreover, since the opening area of the opening part 105 of the cooking chamber 110 will become small if the dimension of the vertical direction of the exhaust flow adjustment board 140 is enlarged, the collection rate of oily smoke and an odor improves. If the collection rate is improved, oily smoke and odor are less likely to leak from the cooking chamber 110, and the oily smoke and odor are sucked into the exhaust part 130 before the inside of the housing 120 is accumulated, so that the heat insulation is improved. 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 this embodiment, the exhaust flow adjusting plate 140 has a horizontally long shape whose longitudinal direction substantially coincides with the length of the opening 105 in the left-right direction.

In consideration of cooking workability, it is sufficient if the opening size in the vertical direction of the opening 105 can be secured at least about 30 cm. That is, the height of the portion where the opening is not blocked may be 30 cm or more. In the present embodiment, this is expressed as 70% or less of the area of the opening 105. In addition, the exhaust flow adjusting plate 140 is 30% or more of the opening 105 in order to effectively exhaust oil smoke and odor in the cooking chamber 110 and to suppress the noise from the exhaust 130. It is desirable to block the area.
(Configuration of opening / closing mechanism of exhaust flow adjusting plate 140)
7A to 7F are views for explaining the opening / closing mechanism of the exhaust flow adjusting plate 140. FIG. As shown in these drawings, the exhaust flow adjusting plate 140 is attached so as to be freely opened and closed by an opening / closing support portion 145 attached to the upper portion of the housing 120.

  FIG. 7A is a cross-sectional view taken along the line B-B of the cooking appliance exhaust device 100 shown in FIG. 2, and shows the exhaust flow adjustment plate 140 and the opening / closing support portion 145 in a state where the exhaust flow adjustment 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 at 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 adjusting plate 140 and the opening / closing support portion 145 in a state where the exhaust flow adjusting 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 adjusting plate 140 is supported by an opening / closing support portion 145 on the upper portion of the housing 120 so as to be freely opened and closed in the direction of the arrow shown. The opening / closing support portion 145 is provided at one side end portion of the exhaust flow adjusting plate 140. The opening / closing support portion 145 may be provided at both end portions (left and right directions in the drawing) of the exhaust flow adjusting plate 140.

  The opening / closing support part 145 can be stored in a storage part 147 provided on the side surface of the housing 120 as shown in FIGS. 7C, 7D, and 7F. The storage unit 147 is a hollow space formed in the side panel 115 of the housing 120 and extending from the front side end of the side panel 115, and the opening at the front side end of the side panel 115 is an exhaust flow adjusting plate When 140 is closed, it is closed by the exhaust flow adjusting plate 140. 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 housed in the housing portion 147, so that oil contamination of the opening / closing support portion 145 can be prevented. Further, the opening of the storage portion 147 is airtight by the plate surface of the exhaust flow adjusting plate 140, and oil stains of the storage portion 147 can be prevented.

  Specifically, as shown in FIG. 7A, in a state where the exhaust flow adjustment plate 140 is closed, the opening / closing support portion 145 is folded and stored in a 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 adjusting plate 140 is opened at the first angle, the second angle, and 90 degrees, the slide 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.

  As described above, the opening / closing support portion 145 of the exhaust flow adjusting plate 140 does not come into contact with the oil smoke when the exhaust flow adjusting plate 140 is closed. When the exhaust flow adjusting plate 140 is closed, the opening / closing support portion 145 enters the hollow space generated by the two-layer structure of the side panel 115. When the exhaust flow adjustment plate 140 is closed, the opening opened to accommodate the opening / closing support portion 145 is covered by the exhaust flow adjustment plate 140. For this reason, the opening / closing support part 145 and the opening do not touch oily smoke.

  Therefore, it is possible to prevent the oil from adhering to and sticking to the opening / closing support portion 145 and to smoothly open and close the exhaust flow adjusting plate 140. Moreover, even if oil adheres to the opening / closing support part 145, the frequency of cleaning is less than that exposed.

Note that the opening / closing support portion uses, for example, a damper, screwing, claw engagement, a roller catch, a magnet, or the like (configuration of the side panel 115).
8 is a cross-sectional view taken along the line C-C of the cooking appliance exhaust device 100 shown in FIG. 3. FIG. 9A is an enlarged view of a portion E of the side panel 115 of the 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. 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 oil smoke or odor in the cooking chamber 110.

  The heat insulating layer is formed by a structure as shown in FIG. 9A or 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 oil smoke and odor heat from the cooking chamber 110 from being transmitted 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, there is no burn. Further, since the heat of oil smoke and odor in the cooking chamber 110 is difficult to be transmitted to the outer panel 115b, the heat during cooking hardly affects the room temperature. Therefore, even when the room is kept cool with an air conditioner in summer, it is difficult to transmit the temperature into the housing 120. Therefore, it is possible to reduce a decrease in the temperature inside the casing 120 and solve the problem that it takes time to increase the temperature of the oil.

  Further, 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 that forms a heat insulating layer is formed between the inner panel 115a and the outer panel 115b. Filled. The heat insulating material 115d prevents oil smoke and odor heat from the cooking chamber 110 from being transmitted from the inner panel 115a to the outer panel 115b. As the heat insulating material 115d, a material having a larger heat insulating effect is preferably used. Moreover, if the heat insulating material 115d is excellent in sound insulation, the cooking sound in the cooking chamber 110 can be effectively absorbed.

  9A and 9B illustrate the case where the air layer 115c is provided and the case where the heat insulating material 115d is filled, 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 to provide a reinforcing material 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 adjusting plate 140 is provided on the front surface of the exhaust portion 130 provided on the upper portion of the housing 120, and the inner surface panel 133 is provided on the lower surface of the exhaust portion 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.

  Moreover, since the heat-insulating layer is provided on the exhaust flow adjusting plate 140 and the side panels 115 and 116 of the housing 120, heat during cooking is hardly transmitted, and the safety of the cook can be ensured.

[Embodiment 2]
This embodiment is an embodiment in which a vortex plate is provided inside the exhaust flow adjusting plate 140 of the cooking appliance exhaust device 100 according to the first embodiment.

  The present embodiment is the same as the cooking appliance exhaust device 100 according to the first embodiment except that a suppression plate is provided inside the exhaust flow adjusting plate 140. Therefore, only the configuration and operation of the suppression plate will be described.

  FIG. 10A is a diagram illustrating a first aspect of the exhaust flow adjusting plate 140, which is the cooking appliance exhaust device 100 according to the second embodiment. FIG. 10B is a diagram showing a second mode of the exhaust flow adjusting plate 140. FIG. 10C is a diagram showing a third mode of the exhaust flow adjusting plate 140.

  As shown in FIGS. 10A to 10C, the suppression plate 150 protrudes linearly toward the rectifying plate 138 or protrudes curvedly toward the rectifying plate 138. The suppression plate 150 of the first aspect shown in FIG. 10A protrudes vertically from the inner surface of the exhaust flow adjustment plate 140 toward the rectifying plate 138. The suppression plate 150 extends linearly in the longitudinal direction of the exhaust flow adjustment plate 140 (from the front side to the back side of the paper surface of FIG. 10A). For this reason, the exhaust flow guided from the cooking chamber 110 (see FIG. 2) to the inner surface panel 133 is blocked by the suppression plate 150, and becomes a vortex between the inner surface of the exhaust flow adjustment plate 140 and the inner surface of the suppression plate 150. The flow rate can be adjusted. In addition, since the exhaust flow that has not been exhausted flowing from the top to the bottom of the exhaust flow adjusting plate 140 is redirected by the suppression plate 150, it can be prevented from leaking into the room. The suppression plate 150 may be provided over the entire longitudinal direction width of the exhaust flow adjusting plate 140 or may be provided partially.

  The restraint plate 150 of the second mode shown in FIG. 10B is curved and protrudes upward from the inner surface of the exhaust flow adjustment plate 140 toward the rectifying plate 138. The suppression plate 150 extends in the longitudinal direction of the exhaust flow adjustment plate 140 in the same manner as the suppression plate 150 of FIG. 10A.

  The restraint plate 150 of the third aspect shown in FIG. 10C has the attachment position of the restraint plate 150 shown in FIG. 10B on the lower surface side of the exhaust flow adjustment plate 140.

  Thus, by providing the suppression plate 150 of the first to third aspects of the present embodiment, the flow rate of the exhaust flow can be adjusted, and leakage of the exhaust flow that could not be exhausted to the indoor side can also be prevented. In addition, the shape and protrusion length of the suppression board 150 can be suitably changed according to the desired purpose. For example, the shape of the suppression plate 150 may be L-shaped, or may be a shape that extends linearly in the rear side and obliquely upward.

[Embodiment 3]
The third embodiment is an embodiment in which the plate surface of the rectifying plate 138 of the cooking appliance exhaust device 100 according to the first embodiment is arranged in parallel to the plate surface of the inner panel 133.

  FIG. 11 is a diagram illustrating a cross section of the exhaust unit 130 in the cooking apparatus exhaust device 100 according to the third embodiment. FIG. 12 is a view showing an exhaust flow path formed around the rectifying plate 138 by the inner surface panel 133 and the rectifying plate 138 of the exhaust part 130 shown in FIG. 12 is a view of the lower part of the exhaust part 130 as seen from the direction of the white arrow in FIG. The white arrow direction is a direction orthogonal to the plate surface of the inner panel 133.

  The present embodiment is the same as the cooking appliance exhaust device 100 according to the first embodiment, except that the plate surface of the rectifying plate 138 is arranged in parallel to the plate surface of the inner panel 133.

  When the plate surface of the rectifying plate 138 is arranged in parallel to the plate surface of the inner surface panel 133, the flow rate of oil smoke and odor in the cooking chamber 110 (see FIG. 2) is increased, and a flow path is formed that flows without stagnation.

  As shown in FIG. 12, the rectifying plate 138 is arranged so that the flow path on the front side is larger than the flow path on the rear side of the casing 120. Thereby, the amount of air sucked from the front side of the cooking chamber 110 becomes larger than the amount of air sucked from the rear side.

  Specifically, as shown in FIG. 12, the width of the exhaust flow path formed by the inner surface panel 133 and the rectifying plate 138 in the direction of the side panels 115 and 116 of the housing 120 is c. Further, the width of the exhaust flow path formed by the inner panel 133 and the rectifying plate 138 in the direction of the exhaust flow adjusting plate 140 is a. Furthermore, the width of the exhaust passage formed by the inner surface panel 133 and the rectifying plate 138 in the direction of the rear panel 117 of the housing 120 is a. The widths of these exhaust passages have a relationship of a> c> b.

  If the size of the exhaust passage formed around the rectifying plate 138 is made uneven by the inner surface panel 133 and the rectifying plate 138, the amount of oil smoke and odor flowing from the cooking chamber 110 to the inside of the case 120 is reduced. It can be adjusted for each direction.

[Embodiment 4]
The fourth embodiment is an embodiment in which the exhaust flow adjusting plate 140 of the cooking appliance exhaust device 100 according to the first embodiment is detachable.

  FIG. 13 is a perspective view of the cooking appliance exhaust device according to the fourth embodiment. The cooking apparatus exhaust apparatus 100 according to the present embodiment is configured such that the exhaust flow adjusting plate 140 of the first embodiment can be removed. FIG. 13 shows a state in which the exhaust flow adjusting plate 140 is removed.

  If the exhaust flow adjusting plate 140 is detachable, the exhaust flow adjusting plate 140 itself can be easily cleaned. Moreover, since the opening area of the opening part 105 of the cooking chamber 110 becomes large, cleaning of the inner surface panel 133 and the baffle plate 138 becomes easy.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to said embodiment, It can implement as various forms based on the technical idea described in the claim. Needless to say, they are also within the scope of the present invention.
