Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking grill for cooking an object to be cooked, such as fish, on a grill in the grill by heating it with the heat of the gas burner. The present invention relates to a cooking grill having a function of adjusting the exhaust resistance of the combustion gas in the grill chamber discharged from the exhaust port immediately after ignition until reaching a heat stable state.

[0002]

2. Description of the Related Art Conventionally, as this type of cooking grill,
What cooks food such as fish placed on the grill in the grill and ignites the gas burner provided on the inner wall of the grill, and heats the cook by the flame of the gas burner and the heat of the combustion gas. Is commonly known. The combustion gas is exhausted from the exhaust port that is usually provided in the depth of the grill, but the combustion gas that retains thermal energy due to the combustion of the gas is sufficient to heat the food. Being exhausted without being used, the heating efficiency of the food to be cooked decreases, it takes time to cook the food to be cooked, or the food to be cooked does not burn well, and the cooking performance of the grill deteriorates. In the first place, gas consumption increases and it is very uneconomical.

Therefore, in order to improve the cooking performance and thermal efficiency of such a grill, the exhaust area of the exhaust port provided at the depth of the grill cabinet is made small so that the combustion gas exhausted from the exhaust port is reduced. It is well known that the technical measure of increasing exhaust resistance has been generally adopted. As a result, the combustion gas in the grill cabinet is kept as much as possible in the grill cabinet, and the gas heat is used to heat the food to be cooked.

[0004]

However, according to such a generally known cooking grill, it is effective at the time when the gas burner is ignited and the inside of the grill is filled with the combustion gas and becomes in a heat stable state. Is. In other words, the combustion gas with sufficient heat in the grill chamber stays in the grill chamber for a long time before being discharged from the exhaust port, and the heat of this combustion gas is effectively used to heat the food to be cooked. Will be.

On the other hand, however, in a state where the exhaust resistance of the exhaust port from which the combustion gas is exhausted remains large, the exhaust port is still immediately after the food is placed on the grill in the grill and the gas burner is ignited. Because the exhausted combustion gas draft is not effective, the exhaust resistance is too large and the inside of the chamber is O ₂
It was feared that there would be a shortage and the ignition transfer at the initial stage of ignition would not be successful, resulting in poor ignition.

Further, the supply of combustion air (secondary air) supplied from the lower side of the grill in the grill chamber is insufficient because the draft at the exhaust port is not yet effective, and complete combustion cannot be obtained. , Furthermore, because the draft does not work, the intake of primary air for combustion into the gas burner becomes insufficient, resulting in a gas-rich mixture, and the combustion speed may be delayed than the outflow speed from the flame mouth, causing a lifting phenomenon. There was also a problem.

The present invention has been made in order to solve such a problem, and an object of the present invention is to make a gas burner poorly ignited or combustible immediately after ignition due to a large exhaust resistance in a grill cabinet. It is an object of the present invention to provide a cooking grill in which the above-mentioned problem is solved or adverse effects such as lifting phenomenon are avoided.

[0008]

In order to achieve this object, the cooking grill of the present invention is provided with a gas burner for heating and cooking an object to be cooked, such as fish, on the inner wall surface of the grill chamber and the depth of the grill chamber. Is provided with an exhaust port for discharging the combustion gas from the gas burner, and the exhaust flow path of the combustion gas leading to the exhaust port has a small exhaust resistance of the combustion gas discharged from the exhaust port at the time of ignition of the gas burner,
The gist is that exhaust resistance adjusting means is provided for variably adjusting the exhaust resistance so that the exhaust resistance increases as the temperature inside the grill increases.

In this case, a partition is provided in the depth of the grill compartment to separate the cooked product side and the exhaust port side, and the first exhaust flow path is formed on the lower side of the partition and an appropriate portion of the partition is provided. A second exhaust passage is formed in the second exhaust passage, and an opening / closing member for opening / closing the second exhaust passage is provided in the second exhaust passage. The opening / closing member is open at the time of ignition of the gas burner. It is desirable to control the opening and closing so that it closes when the temperature inside the refrigerator rises.

Further, in this case, as means for controlling the opening / closing of the opening / closing member, the opening / closing member is urged to open / close via the heat responsive member, and the heat responsive member senses the heat of the combustion gas so that the second A preferred embodiment is one in which the exhaust passage of is configured to be closed.

In the second cooking grill of the present invention, a gas burner for heating and cooking an object to be cooked such as fish is provided on the left and right inner wall surfaces of the grill cabinet, and the combustion gas generated by the gas burner is provided in the depth section of the grill cabinet. Is provided with an exhaust port for discharging the gas, and a partition wall for partitioning the cooked object side and the exhaust port side is provided in the depth part of the grill cabinet.
The exhaust flow path of the
Of the second exhaust flow passage is provided with an opening / closing member for opening and closing the second exhaust flow passage, and the opening / closing member is open at the time of ignition of the gas burner and is open in the grill cabinet. The gist is that the opening and closing is controlled so as to close when the temperature rises.

In particular, the cooking grill of the second invention is
Compared to the heating method in which side burners are provided on both the left and right sides of the inner wall of the grill cabinet (which replaces the conventional gas burner on the ceiling surface), the heating efficiency of the cooked food on the grill is inferior. It is effective as a solution to the drawbacks. The side burner type has the advantage that the height of the grill can be reduced, but the grilling performance is inferior to that of the ceiling burner type and it is difficult to grill to the middle. Therefore, it can be covered by applying the present invention.

[0013]

According to the cooking grill of the present invention having the above structure, according to the first aspect of the invention, the fish set in the grill by the gas burner provided on the inner wall surface of the grill. The food to be cooked is heated and cooked, and the combustion gas of the gas burner is exhausted from the exhaust port provided in the depth of the grill cabinet, but when the gas burner is ignited, the exhaust resistance of the combustion gas exhausted from the exhaust port is Even if the draft of the exhaust port is not effective because it is small, it is ignited quickly, and if the temperature in the grill chamber rises due to continued combustion, the exhaust resistance increases, so the combustion gas stays in the grill chamber for as long as possible. And stays and is used for heating the food.

In this case, according to the second aspect, at the time of ignition of the gas burner, not only the first exhaust passage formed on the lower side of the partition wall provided at the depth of the grill cabinet, Since the second exhaust passage formed at an appropriate portion of the partition wall is also opened, the exhaust resistance is small, and the gas burner is quickly ignited even if the draft does not work. When the temperature inside the grill chamber rises and the second exhaust passage is closed, the combustion gas is exhausted from the exhaust port only through the first exhaust passage, so the exhaust resistance rises, and as a result, After all, the combustion gas stays in the grill for a long time as much as possible, and the food to be cooked is efficiently cooked.

According to the second aspect of the present invention, the food to be cooked in the grill cabinet is heated and cooked by the heat of the gas burners provided on both left and right sides of the grill cabinet,
The operation is the same as in the case of claim 2 described above, and therefore will be omitted. However, in the case of a heating method using a side burner, in particular, the partition wall provided in the depth of the grill chamber prevents the flow of combustion gas through the exhaust port, and the partition wall provides a combustion gas trapping state. The decrease in heating efficiency of the cooked food due to the burner method is eliminated.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows an example in which a cooking grill according to an embodiment of the present invention is applied to a table stove.
As shown in the figure, in this table stove 10, gas stoves 14a and 14b are arranged on the surface of the table top plate 12, while spark plugs 18a and 18b of the gas stoves 14a and 14b are provided on the surface of the front plate 16 respectively. . A cooking grill 20 for heating an object to be cooked such as fish is provided at the center of the table stove 10.

FIG. 2 shows the internal structure of the cooking grill 20. As shown in the figure, the grill 20 for cooking is provided with a grill 24 for placing an object to be cooked F such as fish in a grill cabinet 22 having a depth. Upper fire burners 26a and 26b (only the upper fire burner 26a on one wall is shown in this drawing) are provided facing each other on the inner wall surface of the. Further, lower fire burners 27a and 27b (only the lower fire burner 27a of one wall is shown) are provided facing each other on both side walls of the grill under the grill 24.

As the upper fire burners 26a and 26b, all primary combustion type burners are used in this embodiment. Although the details are omitted because they are not the gist of the present invention, a heat radiation plate made of a ceramic material having innumerable flame openings is provided on the inner wall surface of the grill cabinet 22, and a gas pipeline provided on the back side of the heat radiation plate. When a mixture of fuel gas and air is sent through the air-fuel mixture and the mixture is blown out from the flame mouth of the heat radiation plate into the grill chamber 22, it burns on the surface of the heat radiation plate, The upper surface of the cooking target F is heated by radiant heat. Also, the lower heat burners 27a, 27
In b, a Bunsen burner is used to heat the lower surface of the food F.

An exhaust port 28 for exhausting combustion gas generated by heating of the upper fire burners 26a and 26b and the lower fire burners 27a and 27b in the grill cabinet 22 is provided at the depth of the grill cabinet 22 at the table stove 10. A partition wall 30 is provided facing the surface 12 of the table top and partitioning the inside of the grill 22 into the cooked food F side and the exhaust port 28 side. The lower end of the partition wall 30 extends below the height of the grill 24 so that the combustion gas generated by the ignition combustion of the upper burners 26a and 26b passes through the lower side of the partition wall 30. A first exhaust passage 32 is formed to be discharged from the exhaust port 28.

On the other hand, on the upper wall surface portion of the partition wall 30, there is provided a vent hole 34 through which the combustion gas in the grill case 22 can flow toward the exhaust port 28, and the upper fire burners 26a, 26b and the lower fire burner 27a, A second exhaust flow path 36 is formed through which the combustion gas from 27b passes through the vent hole 34 and is discharged from the exhaust port 28. The vent hole 34 is provided with an opening / closing lid 38 for opening and closing the vent hole 34.
That is, in the first embodiment shown in FIG. 2, one end of the opening / closing lid 38 is pivotally attached to the partition wall 30 via the support shaft 40, and the other end side of the opening / closing lid 38 is connected via the shape memory alloy spring 42. At room temperature, the vent hole 34 is open, and the shape memory alloy spring 42 is urged to open and close by sensing the heat of the combustion gas passing through the vent hole 34. The shape memory alloy spring 42 of this embodiment is a heat responsive member which is made of a bidirectional shape memory alloy material which is contracted at room temperature and has an expansion and contraction characteristic of being expanded by heat.

Returning to FIG. 1, the auxiliary members of the cooking grill 20 will be described. In order to put a food item F such as fish in and out of the cooking grill 20 on the front plate 16 of the table stove 10. An opening / closing door 44 of the grille 22 is provided on the front plate 16 of the opening / closing door 44.
a, 26b and the spark plug 4 of the lower heat burner 27a, 27b
6 is provided.

According to the cooking grill 20 thus constructed, the opening / closing door 44 is now opened and the grill cabinet 22 is opened.
When the material to be cooked F is placed on the grill 24 inside and the ignition plug 46 is twisted to ignite the upper fire burners 26a and 26b and the lower fire burners 27a and 27b in the grill chamber 22, the ignition time is still at the grill chamber. Although the flow of the combustion gas toward the exhaust port 28 is not generated in the inside of 22 and the draft is not effective, in addition to the first exhaust passage 32 provided in the lower portion of the partition wall 30, Since the vent hole 34 forming the exhaust passage 36 is open, the exhaust resistance leading to the exhaust port 28 is not so large.

Therefore, the transition of ignition of the upper burners 26a, 26b and the lower burners 27a, 27b at the time of ignition is successful, ignition is performed safely and reliably, and the combustion gas immediately after ignition is especially the second exhaust gas flow. It is promptly guided to the exhaust port 28 through the passage 36. The rapid combustion gas flow causes the upper-burner 26a, 26b and the lower-burner 27a, 27b themselves to smoothly supply the air-fuel mixture, and the combustion speed of the air-fuel mixture becomes the outflow speed from the flame mouth. It is avoided that the lifting phenomenon occurs later than that, and the supply of the secondary air into the grill cabinet 22 (supplied from the lower side of the opening / closing door 44 into the grill cabinet 22) is immediately started, which is good. An ignition combustion state is obtained.

When the combustion gas flows from the second exhaust passage 36, the heat of the combustion gas is sensed by the shape memory alloy spring 42, and the shape memory alloy spring 42 expands to cause the opening / closing lid 38. The ventilation hole 34 is closed. As a result, the exhaust of the combustion gas from the second exhaust passage 36 is stopped, and the outflow of the combustion gas in the grill case 22 to the exhaust port 28 is prevented from flowing through the first exhaust passage 3 provided below the partition wall 30.
It will be done only through 2. Therefore, since the exhaust resistance of the combustion gas leading to the exhaust port 28 becomes large, the residence time of the combustion gas in the grill case 22 becomes long, and the heat of the combustion gas is sufficiently used for heating the food F. Then, the combustion gas whose temperature has been lowered is discharged from the exhaust port 28.

FIG. 3 shows an exhaust structure of a cooking grill according to a second embodiment of the present invention. In this embodiment, an opening / closing lid made of a bimetal material is used instead of the opening / closing of the opening / closing lid by the shape memory alloy spring 42 as the heat responsive member. That is, as shown in FIG. 3, in the second embodiment, the opening / closing lid 50 made of a bimetal material is attached to the vent hole 34 provided in the partition wall 30 to form the second exhaust flow passage 36, and one end of which is screwed. 51 It is provided by stopping. The opening / closing lid 50 made of the bimetal material has the vent holes 34 opened at room temperature, and the thermal expansion of the cooking target F side is performed so that the vent holes 34 are closed by sensing the heat of the combustion gas passing through the vent holes 34. Exhaust port 28 with small coefficient
It is configured by bonding metal materials having a large thermal expansion coefficient on the side.

Thus, also in this second embodiment, as in the case of the first embodiment described above, the vent hole 3 is provided at the time of ignition of the upper fire burners 26a, 26b and the lower fire burners 27a, 27b.
Since 4 is open and the exhaust resistance leading to the exhaust port 28 is not so great, the ignition of the upper flame burners 26a, 26b and the lower flame burners 27a, 27b can be performed smoothly and safely.

The exhaust port 28 is ignited by ignition of the gas burner.
When the discharge of the combustion gas to the second exhaust passage 36 is started, the bimetal material opening / closing lid 50 of the ventilation hole 34 provided in the second exhaust passage 36 detects the heat of the combustion gas and closes the ventilation hole 34. The exhaust resistance leading to the exhaust port 28 in the grill case 22 increases. Therefore, after the second exhaust flow path 36 is closed, the combustion gas in the grill case 22 remains in the grill case 2.
After the thermal energy stays in the chamber 2 for a relatively long time and is used for heating the food F, the temperature is lowered and the exhaust port 2 passes through the first exhaust passage 32 provided in the lower portion of the partition wall 30.
8 and is discharged.

In the case of the second embodiment as well, at the time of ignition, the exhaust gas resistance in the grill case 22 is small, so that a rapid flow of combustion gas is generated, so that the upper burner 26 is discharged.
a, 26b and the lower heat burners 27a, 27b themselves are smoothly supplied to prevent the lifting phenomenon from occurring, and the secondary air supply to the inside of the grill 22 is immediately started, which is preferable. Therefore, a good ignition combustion state can be obtained.

The embodiment shown in FIG. 4 is a modification of the second embodiment shown in FIG. That is, in this embodiment, the opening / closing lid made of the bimetal material is used as the second exhaust passage 36.
Instead of being provided in the vent hole 34, it is provided in the outlet 52 of the second exhaust passage 36 that communicates with the exhaust port 28.

Also in the modification shown in FIG. 4, the opening / closing lid 50 made of the bimetal material has the second exhaust passage 36 opened at room temperature, and the thermal expansion of the opening / closing lid 50 is closed by sensing the heat of the combustion gas. It is composed by laminating two kinds of materials having different coefficients, which is the second one shown in FIG.
This is the same as the case of the embodiment.

Also in the modification shown in FIG. 4, the second exhaust passage 36 is opened at the time of ignition so that the gas burner is smoothly ignited, and the second flow path of the combustion gas causes the second exhaust passage 36 to ignite.
After the exhaust gas flow path 36 is closed, the combustion gas in the grill case 22 is discharged through the first exhaust gas flow path 32 on the lower side of the partition wall 30, so that the cooked food F has good cookability. Will be things.

FIG. 5 shows still another embodiment of the present invention. In the embodiment shown in FIGS. 5A and 5B, the oil damper member 54 for opening / closing the opening / closing door 38 of the ventilation hole 34 and the gas burners 26a, 26b, 2 are provided.
An operating member 56 that rotates in conjunction with the ignition plug 46 that ignites 7a and 27b, and a link member 58 that connects the operating member 56 and the oil damper member 54 are attached to the inner wall surface of the grill case 22. There is. When the spark plugs 46 of the gas burners 26a, 26b, 27a, 27b are turned to ignite the burners, at the same time, the operating member 56 in the grill case 22 is rotated as indicated by the arrow in FIG. As the oil damper member 54 is operated via 58, the opening / closing door 38a of the vent hole 34 is opened and the oil damper member 54 is opened.
The second exhaust passage 36 is opened as shown in (b). Therefore, the exhaust resistance to the exhaust port 28 at the time of ignition is small, and the ignition of the gas burners 26a, 26b, 27a, 27b is smoothly transferred to the ignition so that ignition failure does not occur and a good ignition combustion state is ensured. Is obtained.

After the gas burner is ignited, the oil damper member 54 is automatically returned to the position shown in FIG.
It returns to the original state shown in (a). Therefore grill room 2
Under the stable combustion condition in 2, the opening / closing door 3 of the vent hole 34
8a is closed and the second exhaust passage 36 is closed, so that the combustion gas in the grill case 22 passes through the first exhaust passage 32 provided exclusively below the partition wall 30 and the exhaust port 2a.
We are going to 8. In this state, the second exhaust passage 3
As described above, since 6 is closed, the exhaust resistance of the combustion gas is large, and the cooking target F is effectively heated by the combustion gas.

FIG. 6 shows another embodiment of the present invention.
In this embodiment, the gas burners 26a, 26b, 27a,
The micro switch 60 is turned on by the rotation of the operation member 56 on the inner wall surface of the grill case 22 which is interlocked with the operation of the spark plug 46 for igniting 27b, and the eccentricity provided on the drive shaft of the motor 62 by the ON signal of the my roller switch 60. The cam member 64 rotates, and as shown by the solid line in FIG. 6, the opening / closing door 38a of the ventilation hole 34 is opened to form the second exhaust passage 36. At the same time, the timer 68 of the controller 66 is activated to allow the motor 62 to restart after a certain period of time elapses when the gas combustion state in the grill case 22 is stabilized.
Is driven again to open and close the door 3 as shown by the phantom line in FIG.
8a is closed, and the second exhaust flow path 36 is closed.

Also in this embodiment shown in FIG. 6, since the second exhaust passage 36 is opened immediately after the ignition of the gas burner, the exhaust resistance of the combustion gas in the grill case 22 is small and a smooth ignition operation is possible. The second exhaust flow path 3
In the stable combustion state where 6 is closed, the exhaust resistance of the combustion gas in the grill case 22 is large, so that the cooking target F is quickly cooked.

In the embodiment of FIG. 6, the opening / closing door 38a of the vent hole 34 is opened / closed by driving the motor 62, but this is not to be understood by this, and an electromagnetic solenoid (not shown) is used instead of the motor driving. The opening / closing door 38a is opened by exciting the electromagnetic solenoid based on the ON signal of the micro switch 60, and the opening / closing door 38a is closed by demagnetizing the electromagnetic solenoid after a predetermined time by the timer 68. Also achieves the same purpose.

Further, in the embodiment shown in FIG. 7, the opening / closing door 38a is opened by driving the motor 62 based on the ON signal of the micro switch 60.
A temperature sensor 70 for detecting the exhaust temperature of the combustion gas is provided at the mouth, and when the exhaust temperature of the combustion gas detected by the temperature sensor 70 reaches a predetermined temperature (set temperature), an instruction from the controller 66 is issued. The motor 62 is driven again to close the opening / closing door 38a. The function and effect of this configuration are the same as those in the above-described various embodiments, and therefore will not be described again.

8 (a) and 8 (b) also show another embodiment of the present invention, the operating piece 72 is integrally formed with the opening / closing door 38b from the opening shaft (pivot shaft) 40 portion of the opening / closing door 38b. Piled up,
A spindle 76 that allows the thermoelement member 74 to move back and forth is linked to this. Also in this embodiment, the opening / closing door 38b is normally opened and the second exhaust passage 36 is formed, but the grease (oil) in the thermo element member 74 is ignited by the combustion of the combustion gas in the grill case 22 by the ignition of the burner. When thermally expanded by the temperature of the thermoelement member 7
The spindle 76 of No. 4 moves forward and pushes the operating piece 72 integrated with the opening / closing door 38b, so that the opening / closing door 38b is closed and the second exhaust passage 36 is formed as indicated by a phantom line in FIG. It will be blocked. When the temperature of the inside of the grill case 22 is lowered after using this grill, the volume of grease (oil) in the thermo element member 74 is automatically restored to the original level, so that the opening / closing door 3
8b can be obtained in an open state (that is, a state in which the second exhaust passage 36 is formed) as shown by the solid line in FIG. 8 (a). It can be said that this is in a standby state for the next use of the grill.

FIGS. 9 (a) and 9 (b) also show another embodiment of the present invention. In this embodiment, the gas burners 26a, 26b, 27a, 27b are interlocked with the ignition plug 46 to rotate. The operating member 56 that moves and the operating piece 72 that hangs integrally on the opening shaft (pivot shaft) 40 of the opening / closing door 38b are linked by a link member 58. In this embodiment, the magnet 78 is provided on the upper surface of the opening / closing door 38b, and when the opening / closing door 38b is opened by the burner ignition operation, the magnet 78 sticks to the metal plate on the inner wall surface of the grill and the opening / closing door 38b is released and held. When the inside of the refrigerator 22 becomes hot, the magnetic force of the magnet 78 becomes weaker and moves away from the inner wall surface of the grill.
As shown in (b), the opening / closing door 38b is closed.

8 (a), 8 (b) or 9 shown in FIG.
In the case of the embodiments shown in (a) and (b) as well, the same actions and effects as those of the various embodiments described before can be obtained, and therefore the duplicated description will be omitted. Although various embodiments have been described above, the present invention is not limited to these embodiments, and it goes without saying that various modifications and improvements are applied.

[0041]

As is apparent from the above description, in the cooking grill of the present invention, the exhaust resistance of the combustion gas leading to the exhaust port is small at the normal temperature immediately after or immediately after ignition of the gas burner, and after the ignition of the gas burner. When the flow of the combustion gas occurs, the exhaust resistance becomes large. Therefore, in the ignition operation of the gas burner, the ignition transition does not occur smoothly and the ignition failure does not occur, and after the gas burner is ignited, the combustion gas is not discharged from the exhaust port immediately but rather slightly. Since the food to be cooked stays in the grill for a long time, the food to be cooked can be quickly cooked.
Moreover, in combination with the improvement of the combustibility of the gas burner (securing a sound CO / CO ₂ ratio at the time of ignition, avoiding the lifting phenomenon, etc.), the thermal energy of the combustion gas is sufficiently supplied to the food to be cooked. It is economical and economical.
