BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stove with a grill provided with a grill for heating and cooking an object to be cooked in a grill cabinet.

[0002]

2. Description of the Related Art Conventionally, there is known a general structure of a grill which is capable of heating a cooking object from its entire surface by burning combustion gas, that is, a so-called muffle grill, as shown in FIG. 4, for example. . The grill 200 shown in the figure has a grill 21 on which the food F is placed, a saucer 22 which slides and pulls out the grill 21 while the net 21 is placed thereon, and a primary unit which burns fuel gas to heat the food F. Pneumatic grill burner 2
7 and a grill case 26 for accommodating them, and an exhaust chamber 32 provided at the back of the grill case 26 for guiding the combustion gas generated by the combustion of the grill burner 27 to the outside of the body. The mouth 31 is opened.

A communication port 34 is opened in a partition wall 33 that separates the grill chamber 26 and the exhaust chamber 32, and the upper end of the opening is at a position slightly lower than the surface on which the food F to be cooked is placed on the grill 21. Is formed as. In addition, a cooling passage 23 is provided on the bottom surface of the grill case 26 so as to communicate with the bottom portion of the exhaust chamber 32, and an air introduction port 24 through which external air can enter the cooling passage 23 is opened in the front portion thereof.

In the center of the front of the grill cabinet 26, there are provided a grill handle 15 which is integrally fixed to the pan 22 and pulls the pan 22 forward, and an opening / closing door 16 which opens and closes in conjunction with pulling out the pan 22. The opening / closing door 16 is provided with a peep window 17 made of glass. When the grill handle 15 is pulled out to the front, the tray 22 fixed to the grill handle 15 slides on the bottom surface of the grill cabinet 26, and the grill 21 placed on the tray 22 is pulled out at the same time.

When the grill 200 is ignited, the fuel gas ejected from the grill burner 27 is ignited to start combustion. The generated combustion gas is used for grill 2
6 Withdrawing upwards, the food to be cooked F is wrapped by the heat of combustion to be heated up to every corner for good cooking, and then overflows into the communication port 34 and flows into the exhaust chamber 32, and is exhausted by the draft force.
It rises inside and flows out of the body. Along with this, the outside air flows in from the air introduction port 24 and is sucked into the cooling passage 23 to cool the saucer 22 and prevent the saucer 22 from being heated, so that it can be properly used as a waterless grill.

[0006] In such a grill 200, when it is desired to see the degree of burning of the food F to be cooked in the grill cabinet 26, the grill cabinet 26 is opened through the peep window 17 provided in the opening / closing door 16.
I'm observing the inside.

[0007]

However, when the grill handle 15 is pulled out, the grill 21 and the saucer 22 are simultaneously taken out from the grill cabinet 26, and at the same time, the opening / closing door 16 is opened and closed simultaneously. There is a problem that combustion gas in the grill case 26 leaks out through the gap 18 between the front panel of the stove 100 with a grill and the opening / closing door 16, and the heat efficiency and the cooking performance deteriorate. In such a type that the opening / closing door 16 is opened / closed in conjunction with pulling out the tray 22, the gap 18 cannot be eliminated owing to its structure. Particularly, in the above-described grill that can be grilled, the presence of such a gap 18 has been a serious problem because the combustion gas that has been trapped inside the grill chamber 26 leaks out. Further, since the front part 110A of the top plate 110 is heated by the combustion gas leaking from the gap 18, there is a possibility that the front part 110A of the top plate 110 may be burned when the grill is used. It is an object of the present invention to solve the above problems, to make it easier to observe an object to be cooked in a grill cabinet, and to further improve thermal efficiency and cooking performance.

A handle for removal may be provided on the viewing window 47.
Through the viewing window 47, the cooking status of the food F to be cooked can be confirmed. With such a configuration, the combustion gas does not leak from the front side of the grill case 26.

The front portion 11A of the top plate 11 located above the viewing window 47 is cut out in a U shape as shown in FIG. 2 to form a cutout portion 11B, which does not protrude from the instrument body. . Therefore, there is no obstruction between the upper part of the viewing window 47 and the user's eyes, and the grill cabinet 2
Since the lighting in 6 can be sufficiently obtained, the grill cabinet 26
The inside becomes easier to see.

Next, the operation of the grill 20 will be described.
When the operation button 12c is pushed all the way, gas is supplied to the grill burner 27 and is ignited directly by continuous sparks from an electrode (not shown) to start combustion. Since the generated combustion gas has a high temperature, as shown by a broken line arrow in FIG. 1, the combustion gas is filled in the grill chamber 26 above the communication port 34 and then overflows from the communication port 34 into the exhaust chamber 32, so that the upper exhaust port It is discharged from 31 to the outside.

Therefore, since the food F to be cooked is heated by the high temperature combustion gas accumulated in the upper part of the grill cabinet 26, the thermal energy can be effectively used and the gas consumption amount is small and energy can be saved. Further, since the airtightness of the front side of the grill cabinet 26 is maintained, the combustion gas does not unnecessarily leak from the front side of the grill cabinet 26, and all the combustion gas passes through the exhaust chamber 32 and the exhaust port 31. Since it is discharged from, the cooking target F can be cooked more efficiently. Also, the food to be cooked F
Unlike the conventional grill, the peep window 47 does not open even when the grill door 42 is opened for the purpose of turning back, etc., so that the amount of combustion gas that leaks can be suppressed, and thermal efficiency is further improved. Is improved. In this case, as shown in FIG. 1, if the upper end position of the door opening 41 provided for taking in and out the grill 21 is provided below the grill burner 27, the grill door 42 is opened and the grill is opened. When 21 is pulled out from the grill cabinet 26, high temperature combustion gas trapped in the upper part of the cabinet does not easily overflow from the door opening 41,
It is possible to reduce the temperature drop in the refrigerator, and when the grill 21 is pushed into the grill chamber 26 again, the cooking temperature is promptly restarted at the temperature suitable for the cooking of the food F, and therefore the thermal efficiency is further improved. Even better, the gas consumption can be reduced.

Further, since there is no gap between the viewing window 47 and the front panel 45, which has been present in the conventional grill, the combustion gas trapped above the grill cabinet 26 is generated.
Since it does not leak from the front side, the front portion 11A of the top plate 11 is not heated by the high-temperature combustion gas. Therefore, even if the user touches the front portion 11A of the top plate 11 while using the grill 20, there is no fear of getting burned or the like.

Further, the cooking target F placed in the central portion, which is far from the grill burner 27 and receives little heat by radiant heat, is supplemented with the heating by the convection of the combustion gas, so that the entire cooking target F can be baked more uniformly. . Moreover, since the grill top plate 25 is formed in a V shape, the combustion gas can be more effectively collected in the central portion as shown by the broken line arrow in the figure, and the heating can be performed more uniformly.

When the combustion gas fills the inside of the grill chamber 26 and overflows from the communication port 34 in such moji-yaki cooking, the air in the exhaust chamber 32 rises, and the upstream (exhaust chamber) and downstream (exhaust chamber) of the exhaust port 31 ( A large temperature difference occurs between the exhaust chamber 32 and the outside of the body, and a sufficient upward draft force is generated in the exhaust chamber 32. Due to this sufficient draft force, the combustion gas is smoothly discharged to the outside of the grill through the exhaust chamber 32, and at the same time, the outside air is sucked into the cooling passage 23 from the air introduction port 24 on the bottom surface of the grill case 26, and the lower surface of the pan 22 is provided. It flows along and cools the saucer 22. Thus, the grill is the saucer 22.
It can be properly used as a waterless grill that does not fill with water and can bake the food F to be cooked.

Further, even if the grill burner 27 is forgotten to extinguish the fire or the like, the fallen burned fat G or the dried cooked substance F becomes overheated, and even if an ignition occurs in the grill chamber 26, a porous plate is provided in the exhaust chamber 32. Since the flame shielding device 35 formed in 1 is provided, the flame is blocked by the flame shielding device 35, does not overflow from the exhaust port 31 to the outside of the body, and is extremely safe.

When the burnt condition of the food F being cooked is observed through the peep window 47, the lighting of the inside of the grill 26 is not blocked by the front part 11A of the top plate 11, and more Therefore, the food F to be cooked in the grill cabinet 26 can be observed well, and the deep inside of the grill cabinet 26 can be observed. Moreover, since it is not necessary to look inside the grill cabinet 26 from below the front portion 11A of the top plate 11, the user must be in a middle waist posture when observing the inside of the grill cabinet 26, which is the same as the conventional one. Can be reduced compared to.

Further, since the peep window 47 can be removed by putting a hand in the grill cabinet 26 through the door opening 41 and pushing from inside the grill cabinet 26, the peep window 47 itself and the grill cabinet 26 can be cleaned. Peep window 4 because it can be done easily
7 can be kept clean and the inside of the grill cabinet 26 is easy to see.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the scope of the present invention. is there.

[0029]

As described above in detail, according to the cooking stove with a grill of the present invention, since the combustion gas does not unnecessarily leak from the gap, the cooking energy is heated and cooked with the heat energy generated by the combustion of the fuel gas. It can be used effectively. Furthermore, since the viewing window does not open and close in conjunction with the opening / closing door, it is possible to suppress the amount of combustion gas leaking when the opening / closing door is opened, and it is possible to use heat energy more effectively. In addition, since the combustion gas inside the grill does not leak from the front part of the grill, the front part of the top plate is not heated by the leaked combustion gas. It is safe to touch.
Moreover, since the peep window can be removed, the peep window itself and the inside of the grill can be easily cleaned, so that the peep window can be kept clean and the inside of the grill can be easily viewed forever.

Further, according to the cooking stove with a grill of claim 2 of the present invention, since the combustion gas which is purposely kept inside the grill does not leak out unnecessarily from the gap, it is particularly applied to the grill which can be burnt. In that case, the advantage can be fully exerted. In addition, even when the opening / closing door is opened to return the food to be cooked, the peep window does not open in conjunction with it, so the amount of combustion gas that leaks can be suppressed, further increasing the muffled burning. You can exercise your strengths.
