Description

In the present invention, a cooking heating body that is formed in a flat plate shape along the horizontal direction and in which a heating portion is formed only on the lower surface portion of the upper surface portion and the lower surface portion is disposed on the upper side inside the rectangular parallelepiped heating chamber. Provided,
An exhaust pipe that forms an exhaust passage for guiding the cooked exhaust generated in the heating chamber toward the upper exhaust outlet is disposed on the upper side of one of the four side walls of the heating chamber. Connected in a protruding position,
The present invention relates to a heating cooker in which an exhaust induction path for guiding cooking exhaust generated in the heating chamber to an inflow port on a lower side of the exhaust path is formed between the heating body for cooking and a ceiling portion of the heating chamber.

  Such a cooking device for heating causes the cooking exhaust generated in the heating chamber to flow through the exhaust induction path between the cooking heating body and the ceiling portion of the heating chamber and below the exhaust passage formed inside the exhaust pipe. While being guided to the inlet, the exhaust is discharged from the exhaust outlet at the top of the exhaust pipe. As a conventional example of such a heating cooker, there is a grill provided with a grill burner as a heating body for cooking (for example, , See Patent Document 1).

Incidentally, the grill of Patent Document 1 is an extension cylinder that forms an extension guide path that communicates with the exhaust guide path on the upper side part of the rear side wall part to which the exhaust pipe is connected among the four side wall parts of the heating chamber. The part is provided in a state extending in the horizontal direction, and an exhaust pipe is connected to an end of the extension cylinder part.
That is, the grill of Patent Document 1 is configured such that the cooked exhaust generated in the heating chamber is guided to the exhaust path through the exhaust guide path and the extension guide path.

  In the grill disclosed in Patent Document 1, even if a flame is generated inside the heating chamber due to, for example, ignition of oil flowing out from the cooking object, this flame is caused by the exhaust induction path or the extension induction. In the process of flowing through the passage, the flame is extinguished by contacting and cooling the ceiling of the heating chamber and the upper surface of the grill burner, and in the process of flowing through the exhaust induction passage and the extension induction passage, Even if the fire is not extinguished, the flame can be extinguished by contacting the exhaust pipe and cooling in the process of flowing through the exhaust passage.

  As described above, in the grill disclosed in Patent Document 1, even if a flame is generated inside the heating chamber, since the action of cooling the flame is large, the flame jumps out from the exhaust outlet to the outside. Although it is unthinkable to be in a normal use state, it is desired to enhance the cooling action of the flame in order to further improve safety.

  As a technique for enhancing the cooling action of the flame, Patent Document 2 discloses a technique in which a porous flame extinguishing member constituted by a lath net is installed in a flow path through which cooking exhaust flows, and Patent Document 3 Discloses a technique for forming a flow path through which cooking exhaust flows in a serpentine flow path.

Therefore, it is conceivable to apply the technique disclosed in Patent Document 2 to the grill of Patent Document 1 and provide, for example, a porous flame-extinguishing member in a state crossing the exhaust passage (hereinafter referred to as a first assumed conventional example). Called).
In addition, the technique disclosed in Patent Document 3 is applied to the grill of Patent Document 1, and a meandering exhaust passage that communicates with the exhaust guide path or the extension guide path is provided. It is conceivable to connect an exhaust pipe to (hereinafter referred to as a second assumed conventional example).

JP 2003-135286 A JP 2008-194372 A JP 2000-111052 A

  In the first assumed conventional example, even if the flame flows in the exhaust passage, the flame is appropriately cooled and extinguished by the cooling action of the porous flame extinguishing member provided across the exhaust passage. However, since the flame extinguishing member composed of a lath net is expensive, there is a disadvantage that the manufacturing cost increases.

  In the second assumed conventional example, even though the flame flows into the exhaust passage due to the cooling action of the meandering exhaust passage, the flame can be appropriately cooled and extinguished. Since the overall configuration is complicated by providing the meandering exhaust passage, the manufacturing cost is considerably increased, and the cooked exhaust is exhausted due to the meandering exhaust passage. Due to the increase in the exhaust resistance, there is a disadvantage that it is difficult to increase the amount of heating for cooking the cooking object.

  The present invention has been made in view of the above circumstances, and its purpose is to suppress an increase in manufacturing cost and to suppress a flame cooling action while suppressing an increase in exhaust resistance for exhausting cooked exhaust. It is in the point of providing the heating cooker which can raise and improve safety | security further.

The cooking device according to the present invention is formed in a flat plate shape along the horizontal direction, and the heating body for cooking in which the heating portion is formed only on the lower surface portion of the upper surface portion and the lower surface portion is the interior of the rectangular parallelepiped heating chamber. Provided on the upper side of
An exhaust pipe that forms an exhaust passage for guiding the cooked exhaust generated in the heating chamber toward the upper exhaust outlet is disposed on the upper side of one of the four side walls of the heating chamber. Connected in a protruding position,
Between the heating body for cooking and the ceiling part of the heating chamber, an exhaust induction path for guiding cooking exhaust generated in the heating chamber to an inlet on the lower side of the exhaust path is formed, The first characteristic configuration is
A cooling air flow path is formed for flowing cooling air along the upper surface of the ceiling portion of the heating chamber and the outer surface of the exhaust pipe,
A deflecting plate portion is provided for deflecting the cooked exhaust flowing in the exhaust passage toward the inner surface of the exhaust pipe.

  That is, when the cooking exhaust flows through the exhaust passage, the exhaust pipe becomes in a high temperature state, so that an upwardly flowing air flow is generated in the outer peripheral portion of the exhaust pipe, and the draft action by the air flow causes an external flow. Air can be introduced into the cooling air flow path as cooling air, and the cooling air can be flowed through the cooling air flow path to cool the ceiling portion of the heating chamber and the exhaust pipe.

Therefore, in the unlikely event that a flame is generated inside the heating chamber due to, for example, ignition of oil flowing out from the object to be cooked, in the process of this flame flowing through the exhaust induction path, The flame is extinguished by being cooled in contact with the upper surface of the grill burner.
In particular, since the ceiling portion of the heating chamber is cooled by the cooling air flowing through the cooling air flow path, the cooling action of the flame is appropriately exhibited.

Further, even if the flame is not extinguished in the process of flowing through the exhaust guide path, it can be extinguished by contacting the exhaust pipe and being cooled.
In particular, since the exhaust pipe is cooled by the cooling air flowing through the cooling air flow path, the cooling action of the flame is appropriately exhibited.

  In addition, when the flame flows through the exhaust passage, the deflection plate portion deflects the flame toward the inner surface of the exhaust tube, so that the flame flowing through the exhaust passage is in contact with the deflection plate portion. Due to the contact and contact with the exhaust pipe, it is cooled accurately and extinguished.

  As described above, since the cooling action of the flame is enhanced by flowing the cooling air through the cooling air flow path and by providing the deflection plate portion in the exhaust path, the flame is generated inside the heating chamber. Even if it occurs, it can be extinguished accurately.

  The flow of the cooling air through the cooling air flow path can be performed by using the draft action of the air flow rising and flowing in the outer peripheral portion of the exhaust pipe. Therefore, it is possible to enhance the cooling effect of the flame while suppressing an increase in manufacturing cost.

  Further, since the deflecting plate portion simply changes the direction in which the cooked exhaust flows, it is possible to suppress an increase in exhaust resistance for exhausting the cooked exhaust by installing the deflecting plate portion.

  In short, according to the first characteristic configuration of the present invention, it is possible to further improve safety by suppressing an increase in manufacturing cost and further suppressing an increase in exhaust resistance for exhausting cooked exhaust and enhancing a cooling action of the flame. The cooking device which can be made can be provided.

In addition to the first feature configuration described above, the second feature configuration of the cooking device according to the present invention includes:
The exhaust pipe has a quadrangular cross section,
A plurality of the deflecting plate portions having different positions in the longitudinal direction of the exhaust passage are alternately installed with respect to a pair of opposing wall portions of the exhaust pipe, and cantilevered from the wall portion It is characterized in that it is provided in a protruding posture protruding in a shape.

  That is, since the exhaust path becomes a bent path due to the presence of the deflecting plate portions alternately installed on the pair of opposing wall portions of the exhaust pipe, when a state in which the flame flows through the exhaust path occurs, While the flowing flame is flowing in a meandering state, it can be cooled by repeatedly contacting the deflecting plate portion and the exhaust tube, so that the flame extinguishing action can be exhibited well.

  In other words, when a state where the flame flows in the exhaust path occurs, the flame flowing in the exhaust path can be sufficiently cooled while being repeatedly brought into contact with the deflector plate and the inner surface of the exhaust path, so that the flame is appropriately extinguished. It becomes possible.

  In short, according to the second characteristic configuration of the present invention, in addition to the operational effects of the first characteristic configuration, it is possible to provide a heating cooker that can accurately extinguish the flame flowing in the exhaust passage.

In addition to the first feature configuration described above, the third feature configuration of the cooking device according to the present invention includes:

The plate portion is provided in a state where the plate portion is supported in a cantilever manner in an inclined posture that extends away from the heating chamber and toward the lower side.

  In other words, even when the flame flows through the exhaust guide passage, it may be extinguished by cooling the flame by contact with the extension cylinder when the flame flows through the extension guide passage. It becomes.

  When the flame flows from the extension cylinder part to the inside of the exhaust pipe without being extinguished when the flame flows through the extension guide path, the flame is caused by the deflection action of the lower deflection plate part. Since the fluid flows while being in contact with the bottom surface of the extension tube portion and the inner surface of the exhaust tube, the cooling operation by the bottom surface of the extension tube portion and the cooling operation by the inner surface of the exhaust tube can be exhibited and the flame can be extinguished.

  In other words, even when the flame flows through the exhaust guide path, it may be extinguished when the flame flows through the extension guide path, and further, the flame flows through the extension guide path. When the state where the flame flows from the extension cylinder part to the inside of the exhaust pipe without being extinguished sometimes, the cooling action by the bottom face of the extension cylinder part and the cooling action by the inner face of the exhaust pipe are accurately exhibited, It is possible to extinguish the flame, and the flame extinguishing function can be improved.

  In short, according to the third characteristic configuration of the present invention, it is possible to provide a heating cooker that can improve the flame extinguishing function in addition to the operational effects of the first characteristic configuration.

In addition to the third feature configuration, the fourth feature configuration of the heating cooker of the present invention,
Of the pair of wall portions located in the perspective direction of the exhaust pipe with respect to the heating chamber, an upper deflection plate portion serving as the deflection plate portion on a heating chamber separation side wall portion located on the side away from the heating chamber. Is provided in a state where it is positioned above the lower deflection plate portion and is supported in a cantilever manner in a posture that extends toward the side closer to the heating chamber. .

  That is, since the exhaust path has a bent path shape due to the presence of the lower deflection plate portion and the upper deflection plate portion, when the flame flows through the exhaust passage, the flowing flame is While being allowed to flow in a meandering state, it can be brought into contact with the lower deflection plate portion and the upper deflection plate portion, and repeatedly brought into contact with the exhaust pipe to be cooled, so that the flame extinguishing action can be satisfactorily exhibited. it can.

  That is, when a state where the flame flows in the exhaust passage occurs, the flame flowing in the exhaust passage is brought into contact with the lower deflection plate portion and the upper deflection plate portion, and repeatedly on the inner surface of the exhaust passage. Since it can fully cool, making it contact, it becomes possible to extinguish exactly.

  In short, according to the fourth characteristic configuration of the present invention, in addition to the operational effects of the third characteristic configuration, it is possible to provide a heating cooker that can more accurately extinguish the flame flowing in the exhaust passage.

In addition to any of the first to fourth characteristic configurations described above, the fifth characteristic configuration of the cooking device according to the present invention is as follows.
The deflecting plate portion is formed of a non-porous plate material.
The non-porous shape means a state where a plurality of holes are formed or a state where no holes are formed at all.

  In other words, the non-porous plate material can be manufactured at a lower cost than the porous plate material, so that the deflecting plate portion can be manufactured at a lower cost. The installation of the plate portion can be performed in a form that reduces the manufacturing cost.

  In short, according to the fifth characteristic configuration of the present invention, in addition to the operational effects of the first to fourth characteristic configurations, it is possible to reduce the manufacturing cost by installing the deflection plate portion in order to enhance the cooling effect of the flame. The cooking device which can be performed with the form which aims at can be provided.

It will be discharged to the place.

(Grill extinguishing structure)
As shown in FIG. 4, a deflection plate portion K that deflects cooking exhaust flowing in the exhaust path R toward the inner surface of the exhaust cylinder 6 is provided.
The deflection plate portion K is formed of a non-porous plate material, and in the present embodiment, two deflection plate portions K having different positions in the longitudinal direction of the exhaust passage R are used. Is provided in a projecting posture in which the exhaust tube 6 is alternately installed with respect to a pair of opposing wall portions 6H and projects in a cantilevered manner from the wall portion 6H.

  Specifically, the deflection plate portion is provided at the lower end portion of the side wall portion 6f of the heating chamber located on the side where the grill chamber 2 is present, of the pair of wall portions 6H positioned in the perspective direction of the exhaust pipe 6 with respect to the grill chamber 2. The lower deflection plate portion 17 as K is provided in a state where it is supported in a cantilever manner in an inclined posture extending away from the grill cabinet 2 and toward the lower side.

The deflecting plate portion 18 is provided in a state where the deflecting plate portion 18 is positioned above the lower deflecting plate portion 17 and is supported in a cantilever manner so as to extend toward the side closer to the grill box 2. .

Incidentally, the length corresponding to the lateral width direction of the exhaust passage R of the lower deflection plate portion 17 and the upper deflection plate portion 18 is the length over the entire width of the exhaust passage R in this embodiment. However, the length may be slightly shorter than the lateral width of the exhaust path R.
Further, the protruding length corresponding to the front-rear width direction of the exhaust passage R of the lower deflection plate portion 17 and the upper deflection plate portion 18 is about half the front-rear width of the exhaust passage R in this embodiment. However, it may be implemented in a form that is longer or shorter than this length.

Therefore, even if a flame is generated inside the grill 2 due to ignition of the oil flowing out from the cooking object 3 inside the grill 2, this flame is generated by the exhaust guide path 14 or the extension guide. In the process of flowing through the passage 14T, the flame is extinguished by contacting and cooling the ceiling 2a of the grill cabinet 2 and the upper surface of the grill burner 1.
In particular, the ceiling portion 2a of the grill cabinet 2 is cooled by the cooling air flowing through the cooling air flow path Q, so that the cooling action of the flame is appropriately exhibited.

Further, even if the flame does not extinguish in the process of flowing through the exhaust guiding path 14 and the extended guiding path 14T, the flame is brought into contact with the exhaust pipe 6 in the process of flowing through the exhaust path R to be cooled and extinguished. It will be.
In particular, since the exhaust pipe 6 is cooled by the cooling air flowing through the cooling air flow path Q, the cooling action of the flame is appropriately exhibited.

  Moreover, since the flame is deflected toward the inner surface of the exhaust cylinder 6 by the deflecting plate portion K when the flame flows in the exhaust path R, the flame flowing in the exhaust path R is deflected. By the contact with the plate part K and the contact with the exhaust pipe 6, it is cooled accurately and extinguished.

  According to this embodiment, the lower deflection plate portion 17 and the upper deflection plate portion 18 form a bent path in which the exhaust path R flows in a meandering state. It is possible to bring out the flame extinguishing effect satisfactorily by bringing the deflecting plate portion 17 and the upper deflecting plate portion 18 into contact with each other and additionally bringing the flame into contact with the exhaust pipe 6.

  Further, the lower deflection plate portion 17 is supported in a cantilever manner on the lower end of the heating chamber side wall portion 6f of the exhaust pipe 6 in an inclined posture extending away from the grill box 2 and toward the lower side. Since the flame flowing from the extension guide path 14T to the exhaust path R is brought into contact with the lower surface of the extension cylinder part 2T and the inner surface of the heating chamber separating side wall part 6r of the exhaust cylinder 6, the flame extinguishing action is achieved. It can be exhibited well.

[Another embodiment]
Next, another embodiment is listed.
(1) In the above embodiment, the case where two deflection plate portions K are installed as the deflection plate portions K alternately installed on the pair of opposing wall portions 6H of the exhaust pipe 6 is exemplified. One or more deflecting plate portions K may be alternately installed on a pair of opposing wall portions 6H of the exhaust pipe 6.
Further, for example, only one lower deflection plate portion 17 of the lower deflection plate portion 17 and the upper deflection plate portion 18 is installed, and one deflection plate portion K is attached to the wall portion of the exhaust tube 6. You may implement with the form installed in 6H.

(2) In the above-described embodiment, the pair of wall portions 6H facing the exhaust tube 6 are a pair of wall portions 6H positioned in the perspective direction of the exhaust tube 6 with respect to the grill box 2, that is, the heating chamber existence side wall portion 6f. Although the case where the deflection plate K is installed on the heating chamber separation side wall 6r is illustrated, a pair of wall portions 6H positioned in the lateral width direction of the exhaust tube 6 as a pair of opposing wall portions 6H of the exhaust tube 6. In addition, a deflection plate K may be installed.

Moreover, as a pair of wall part 6H which the exhaust pipe 6 opposes, a pair of wall part 6H located in the perspective direction with respect to the grill warehouse 2 of the exhaust pipe 6, and a pair of wall part 6H located in the horizontal width direction of the exhaust pipe 6 A deflection plate K may be installed in each of the above.
In this case, it is a matter of course that all the deflecting plate portions K are installed at different positions in the longitudinal direction of the exhaust path R.

(3) In the above-described embodiment, the case where the deflection plate portion K is formed of a plate material in which no hole is formed is exemplified. A plurality of flame passing holes for allowing the flame flowing in the exhaust passage R to pass therethrough may be formed at a location close to the wall portion 6H of the deflecting plate portion K.

  In the case of this configuration, a part of the flame flowing in the exhaust passage R passes through the plurality of flame passage holes without being deflected by the deflecting plate portion K. Since the amount of flame deflected toward the inner surface of the exhaust pipe 6 can be reduced, the temperature rise of the wall portion 6H of the exhaust tube 6 on the side where the deflection plate portion K is supported and the deflection plate portion K are supported. There is an advantage that it is possible to adjust the balance between the temperature rise of the wall portion 6H of the exhaust pipe 6 on the opposite side to the exhaust side.

(4) In the above embodiment, when the extension cylinder portion 2T that forms the extension guide path 14T is provided and the lower deflection plate portion 17 and the upper deflection plate portion 18 are installed as the deflection plate portion K. However, the extension cylinder 2T may be omitted.

(5) In the above embodiment, the case where the exhaust pipe 6 is connected to the rear surface part 2d corresponding to the rear side wall part 2H among the four side wall parts 2H of the grill warehouse 2 as a heating chamber is exemplified. For example, you may implement in the form connected to the side surface part 2c corresponding to the left-right side wall part 2H among the four side wall parts 2H of the grill warehouse 2. FIG.

(6) In the above embodiment, the case where the grill A2 as the heating cooker is equipped on the gas stove is illustrated, but the grill A2 may be formed as a single grill device.

(7) In the above-described embodiment, the case where the grill burner 1 is provided as the cooking heater is illustrated, but the cooking heater may be provided with an electric heater.
