Description

The present invention relates to a grilled stove with a grill used to bake an object to be cooked such as fish.

Grills used to bake fish and other cooked foods and grilled stoves with grills have been widely used in the past.

Then, as such a grill (stove with a grill), Patent Document 1 states.
A grill (stove with a grill) equipped with a grill, a burner for heating the food to be cooked contained in the grill, and an exhaust pipe (exhaust duct) that communicates with the grill and exhausts exhaust gas.
(A) A frame trap is provided in the exhaust stack (exhaust duct) to prevent the flame generated by the ignition in the grill from overflowing from the exhaust stack (exhaust duct) to the outside.
(B) A pipe that allows air to flow in and out of the exhaust stack (exhaust duct) from both ends that are open to the atmosphere outside the exhaust stack (exhaust duct) and flows through the inside penetrates the exhaust stack (exhaust duct). A grill (a stove with a grill) equipped with a frame trap (flame extinguishing member) consisting of a pipe provided so as to cross an exhaust pipe (exhaust duct) is described.

Then, in this grill (conro with grill), the exhaust gas flowing through the exhaust pipe (exhaust duct) flows so as to lick the outer peripheral surface of the pipe, so that even if a flame is generated in the grill. It is said that the flame is cooled and extinguished by contacting the outer peripheral surface of the pipe.

Japanese Patent No. 4678693

As described above, in the case of the grill (conro with grill) of Patent Document 1, the flame generated by the ignition in the grill chamber is extinguished by touching the pipe and being cooled by the air flowing inside the pipe. However, by opening both ends of the pipe to the atmosphere outside the exhaust stack (exhaust duct), air flows into the pipe and it depends on the pipe being cooled, and it depends on the inside of the pipe. Since the amount of air flowing into the pipe is large or small, it is left to the atmosphere and situation at that time (it does not have a configuration for actively inflowing air), so the cooling performance of the pipe is limited, and more. The reality is that there is room for improvement when trying to ensure a reliable flame-extinguishing effect.

The present invention solves the above-mentioned problems, and even if a flame is generated by ignition in the grill, the generated flame is surely cooled and the flame is discharged to the outside from the exhaust stack (exhaust duct). It is an object of the present invention to provide a highly reliable grill and a stove with a grill that can prevent the overflow.

In order to solve the above problems, the stove with a grill of the present invention
A grill storage in which the upper opening is covered with a top plate, a burner for heating the food to be cooked stored in the grill storage, and cooking exhaust generated in the grill storage are outside the case main body. A stove with a grill equipped with an exhaust stack that discharges to the outside and a grill having a flame-extinguishing member that prevents flames generated by ignition in the grill chamber from overflowing from the exhaust stack to the outside.
A hollow cooling pipe is provided on the grill as a flame extinguishing member for cooling and extinguishing the exhaust gas passing through the inside of the exhaust stack.
The top plate is provided with an exhaust port for exhausting cooking exhaust generated in the grill.
The exhaust stack may (a) penetrate the top plate from the lower surface side to the upper surface side with a predetermined gap interposed between the top plate and the peripheral edge of the exhaust port. , (B) A predetermined gap is interposed between the upper end portion and the peripheral edge portion of the exhaust port of the top plate, from the lower surface side of the top plate toward the exhaust port, and does not penetrate the exhaust port. In addition to being arranged in a mode
An intake hole is provided on the front side surface of the case body so as to communicate with the gap via a communication passage in the case body.
One end of the cooling pipe opens toward the front, the bottom, and the direction between the front and the bottom of the case body, and the other end of the cooling pipe is the rear of the case body. It is characterized by opening in either the upward direction and the direction between the rear and the upper direction.

In the present invention, one end and the other end of the cooling pipe are names given to distinguish both ends of the cooling pipe, and one end of the cooling pipe is called one end and the other end. Although the portion is called the other end, both are only relative, and the one end may be called the other end and the other end may be called the other end.

Further, in the present invention, one end of the cooling pipe is opened in any direction of the front, the bottom, and the direction between the front and the bottom, so that the opening is literally exactly forward, the bottom, and the like. It is not limited to the case where the cooling pipe is oriented in any of the directions in between, and as described in the embodiments described later, one end of the cooling pipe is tilted in the front-rear direction (axial direction of the cooling pipe). It also includes openings formed by cutting in an aspect that are obliquely oriented and at the same time oriented in any of the forward, downward, and directions between the front and the bottom. ..

Similarly, the other end of the cooling pipe opening in any direction of the rear, the top, and the direction between the rear and the top literally means that the opening is rear, top, The other end of the cooling pipe is inclined with respect to the front-rear direction (axial direction of the cooling pipe) as described in the embodiment described later, and is not limited to the case where the direction is one of the directions in between. It also includes openings that are diagonally oriented and at the same time oriented in any of the forward, downward, and directions between the front and the bottom, which are formed by cutting in the manner in which is there.

Further, in the stove with a grill of the present invention, as the cooling pipe, a front cooling pipe arranged on the outside of the exhaust stack in a manner in contact with the front outer surface of the exhaust stack, and a rear outer surface of the exhaust stack. It is preferable that at least one of the rear cooling pipes arranged on the outside of the exhaust stack is provided in contact with the exhaust pipe.

Further, as the cooling pipe, both the front side cooling pipe and the rear side cooling pipe are arranged, and
It is preferable that the inside of the exhaust stack is provided with a deflector that deflects the exhaust gas flowing in the exhaust stack to the front side and the rear side.

Further, it is preferable that the cooling pipe is arranged so that the central portion penetrates the exhaust stack in the left-right direction and the one end and the other end are located outside the exhaust stack.

The stove with a grill of the present invention is configured as described above, and the cooling gas (air) can be reliably passed through the cooling pipe. Therefore, a flame is generated by the fire inside the grill. In some cases, this flame is also cooled by the cooling pipe and extinguished.

As a result, it becomes possible to provide a highly reliable stove with a grill that can suppress and prevent the flame from overflowing from the exhaust stack to the outside.

Further, the top plate constituting the stove with a grill of the present invention is provided with an exhaust port for exhausting the cooking exhaust generated in the grill storage, and the exhaust stack is (a) the peripheral edge of the exhaust port of the top plate. A predetermined gap is interposed between the portion and the top plate is penetrated from the lower surface side to the upper surface side, or (b) between the upper end portion and the peripheral portion of the exhaust port of the top plate. It is arranged so as to face the exhaust port from the lower surface side of the top plate and not to penetrate the exhaust port with a predetermined gap interposed therebetween, and on the front side surface of the case body, a continuous passage in the case body. Since the intake hole that communicates with the above-mentioned gap is arranged via the above, the temperature of the air around the exhaust gas rises due to the temperature rise of the exhaust pipe due to the use of the grill, and the draft effect due to the increased temperature air. As a result, an ascending flow is generated in the gap, and air flows in from the intake hole communicating with the gap through the communication passage in the case body.

Then, the air that has flowed into the case body from the intake hole flows through the case body from the front to the rear through the communication passage, and together with the rising flow generated in the gap between the exhaust stack and the peripheral edge of the exhaust port of the top plate. , It leaks from the inside of the case body to the outside.

Here, considering the flow of air flowing into the case body from the intake hole, the air flow includes (a) a flow of air flowing into the case body from the intake hole from the front to the rear, and (b). The flow from downward to upward (upward flow due to the draft effect) generated in the gap between the exhaust port of the top plate and the exhaust stack, (c) the flow from front to rear in (a) above, and (b) above. There is a flow from the direction between the front and the bottom to the direction between the back and the top, which is a mixture of the flow from the bottom to the top of the.

Therefore, as in the present invention, one end of the cooling pipe opens toward the front, the bottom, and the direction between the front and the bottom of the case body, and the other end of the cooling pipe is the case. By making the structure open toward the rear, upper, and between the rear and the upper of the main body, the cooling gas (air) is surely passed through the cooling pipe. Even if a flame is generated by a fire inside the grill, the flame can be efficiently extinguished by cooling the flame with a cooling pipe.

Further, as the cooling pipes, a front cooling pipe arranged on the outside of the exhaust stack in a manner of contacting the front outer surface of the exhaust stack and a cooling pipe arranged on the outside of the exhaust stack in a manner of contacting the rear outer surface of the exhaust stack. If at least one of the rear cooling pipes is provided, there is no risk of obstructing the flow of cooking exhaust gas in the exhaust pipe, and even when dust accumulates on the cooling pipe, the high temperature that passes through the exhaust pipe is high. It is possible to realize a stove with a grill that can suppress the generation of an offensive odor by being heated and decomposed in direct contact with the exhaust gas.

Further, both the front cooling pipe and the rear cooling pipe are arranged as the cooling pipes, and the exhaust flowing in the exhaust stack is deflected to the front side and the rear side inside the exhaust stack. When the body is arranged, the deflector promotes the exhaust flowing in the exhaust stack to come into contact with the inner walls in front of and behind the exhaust stack, so that the flame is effectively cooled and the flame is extinguished. Is done effectively.

Further, when the cooling pipe is arranged so that the central portion penetrates the exhaust pipe in the left-right direction and one end and the other end are located outside the exhaust pipe, the cooling pipe is discharged. Since the portion penetrating the cylinder in the left-right direction is in direct contact with the exhaust gas, a sufficient flame-extinguishing effect can be obtained.

(See Figures 2-5). Further, the grill storage 31 is provided with a rectifying plate 34 for rectifying generated smoke, combustion gas, and the like.

<Characteristic configuration of the stove with a grill according to the first embodiment of the present invention>
Next, the characteristic configuration of the grilled stove 100 according to the first embodiment of the present invention will be described. In the following description, when the stove 100 with a grill is used, the side where the user is normally located (the side where the grill door 33a is provided) is defined as the front, and the left and right when the user is viewed from the front to the rear.

In the first embodiment, an exhaust port 91 (FIG. 1) through which the exhaust pipe H penetrates from the lower surface side to the upper surface side is provided on the back side of the upper surface of the case body 101 covered with the top plate TP. That is, in the stove with grill 100 of the first embodiment, an exhaust port 91 for exhausting the cooking exhaust generated in the grill storage 1 is provided in the region on the back side of the top plate TP, and the exhaust stack H Is configured to penetrate the exhaust port 91 from the lower surface side to the upper surface side of the top plate TP with a gap G interposed between the top plate TP and the peripheral edge portion of the exhaust port 91.

Then, in the stove 100 with a grill of the first embodiment, the flame generated by the ignition in the grill storage 31 is discharged before and after the exhaust pipe H that discharges the cooking exhaust generated in the grill storage 31 to the outside of the case main body 101. A cooling pipe 11 for cooling the exhaust pipe H is provided as a flame extinguishing member for preventing the cylinder H from overflowing to the outside.

More specifically, the grilled stove 100 of the first embodiment is a cooling pipe 11 which is a flame extinguishing member, and is in contact with the front outer surface H1 of the exhaust stack H as shown in FIGS. 2 and 3. It is provided with two cooling pipes, a front cooling pipe 11a arranged on the outside and a rear cooling pipe 11b arranged on the outside of the exhaust stack H in a manner in contact with the rear outer surface H2 of the exhaust stack H.

Further, as shown in FIG. 2, an intake hole 22 is provided on the front side surface (front surface) of the case body 101, and between the grill storage 31 and the top plate TP in the case body 101. The region is configured to function as a communication passage 21 for communicating the gap G between the intake hole 22 and the peripheral portion of the exhaust pipe H and the peripheral portion of the exhaust port 91 of the top plate TP.

That is, when the grill burners 41 and 42 burn, the combustion exhaust gas (cooking exhaust) of the grill burners 41 and 42 flows through the exhaust stack H, so that the temperature of the exhaust stack H rises and becomes near the outer periphery of the exhaust stack H. The existing air is heated, the air existing near the outer periphery of the exhaust stack H rises due to the draft effect, and is discharged to the outside from the gap G between the exhaust stack H and the peripheral edge of the exhaust port 91 of the top plate TP. It is configured as follows.

The air existing near the outer periphery of the exhaust stack H rises and is discharged to the outside through the gap G between the exhaust stack H and the peripheral edge of the exhaust port 91 of the top plate TP, so that the inside of the case body 101 becomes negative pressure. Therefore, air at room temperature flows in from the outside of the case body 101 through the intake holes 22 provided on the front side surface (front surface) of the case body 101.

Then, the air sucked from the intake hole 22 flows from the front to the rear through the communication passage 21, and as described above, from the gap G between the exhaust pipe H and the peripheral edge of the exhaust port 91 of the top plate TP. It will be discharged to the outside.

Note that, in FIG. 2, the air that flows into the case body 101 from the intake hole 22 and flows out from the gap G between the exhaust stack H and the peripheral edge of the exhaust port 91 of the top plate TP via the communication passage 21. The flow of is schematically illustrated by the dashed arrow.

Further, in the grilled stove 100 according to the first embodiment, the end portion of the front cooling pipe 11a is placed on one end side (right side in the first embodiment) of the front cooling pipe 11a in the front-rear direction (in the axial direction of the cooling pipe). An inflow portion 12a that opens toward the front (diagonally forward) is provided by cutting diagonally with respect to the direction (orthogonal direction) (see FIG. 3).

Further, on the other end side of the front cooling pipe 11a (left side in the first embodiment), the rear end is formed by cutting the end of the front cooling pipe 11a diagonally in a manner inclined with respect to the front-rear direction. An outflow portion 13a that opens toward (obliquely rearward) is provided (see FIG. 3).

Two first deflecting bodies 61 (61a, 61b) of the second deflecting body 61b for deflecting toward the inner wall H12 are provided (see FIG. 2).

Since the stove 100 with a grill according to the first embodiment is configured as described above, when a flame is generated in the grill storage 31, the flame passes through the exhaust stack H to cool the front cooling pipe 11a and the rear side. When it reaches the vicinity of the portion where the pipe 11b is in contact, it is cooled by being in contact with the inner wall of the portion in the exhaust stack H.

Further, as described above, deflecting bodies 61 (61a, 61b) for promoting contact with the inner walls (front inner wall H11 and rear inner wall H12) of the exhaust stack H of the cooking exhaust are arranged in the exhaust stack H. Therefore, the cooking exhaust is surely in contact with the inner wall of the exhaust pipe H, and the cooling of the cooking exhaust is promoted.

As a result, even when a flame is generated in the exhaust stack H, it is possible to realize a stove with a grill capable of efficiently extinguishing the flame.

Further, as the cooling pipe 11, the front cooling pipe 11a and the rear cooling pipe 11b are arranged on the outside of the exhaust pipe H, so that there is no risk of obstructing the flow of the cooking exhaust gas in the exhaust pipe. Further, even when dust is accumulated on the front cooling pipe 11a and the rear cooling pipe 11b, it is heated by directly contacting with the high-temperature exhaust gas (cooking exhaust) flowing through the exhaust pipe H and decomposed. It is possible to provide a stove with a grill that can suppress the occurrence of an offensive odor.

When configured as in the second embodiment, the first cooling pipe 111a and the second cooling pipe 111b arranged so as to penetrate the exhaust pipe H come into direct contact with the cooking exhaust flowing through the exhaust pipe H. Therefore, even if a flame is generated inside the exhaust pipe H, it is possible to efficiently extinguish the flame.

Further, also in the case of the second embodiment, the first cooling pipe 111a and the second cooling pipe 111b are provided with the air inflow portions 112a and 112b and the air outflow portions 113a and 113b configured as described above. Therefore, the air sucked from the intake hole 22 on the front surface of the case main body 101 efficiently enters the first cooling pipe from the inflow portions 112a and 112b of the first cooling pipe 111a and the second cooling pipe 111b that open toward the front. Since the air flows into the inside of the second cooling pipe 111a and the second cooling pipe 111b and is discharged to the outside from the outflow portions 113a and 113b, the cooling of the first cooling pipe 111a and the second cooling pipe 111b is promoted. Therefore, from this point as well, it is possible to efficiently extinguish the flame.
