BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking stove equipped with a grill for heating food to be cooked in a grill storage.

[0002]

2. Description of the Related Art Conventionally, as a general structure of a so-called muffled grill, for example, shown in FIG. 4, there is known a general structure of a grill which is capable of heating and cooking an object to be cooked from the entire surface by containing combustion gas. . The illustrated grill 200 includes a grill 21 on which the object F is placed, a tray 22 which is pulled out while sliding the grill 21 thereon, and an all-primary which heats the object F by burning fuel gas. Pneumatic grill burner 2
7, a grill storage 26 for accommodating them, and an exhaust chamber 32 provided at the back of the grill storage 26 and guiding the combustion gas generated by the combustion of the grill burner 27 to the outside of the body. The mouth 31 is opened.

[0003] A communication port 34 is opened in a partition wall 33 that separates the grill chamber 26 from the exhaust chamber 32, and the upper end of the communication port 34 is located at a position slightly lower than the mounting surface of the grill 21 on which the object F is placed. It is formed as follows. In addition, a cooling passage 23 is provided on the bottom surface of the grill storage 26 in communication with the bottom of the exhaust chamber 32, and an air introduction port 24 through which external air can enter the cooling passage 23 is opened at a front portion thereof.

At the center of the front of the grill storage 26, there is provided a grill handle 15 which is fixed integrally with the tray 22 and pulls the tray 22 forward, and an opening / closing door 16 which opens and closes when the tray 22 is pulled out. The opening / closing door 16 is provided with a viewing 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 warehouse 26, and the grill 21 placed on the tray 22 is simultaneously pulled out.

[0005] When an ignition operation is performed on the grill 200, the fuel gas ejected from the grill burner 27 is ignited and combustion starts. The generated combustion gas is stored in the grill storage 2
6, the cooking object F is wrapped by the heat of combustion and is heated to every corner to cook well, and then overflows into the communication port 34 and flows into the exhaust chamber 32, where the exhaust chamber 32 is drafted.
It rises inside and flows out of the body. Accordingly, external air flows in from the air inlet 24 and is sucked into the cooling passage 23 to cool the tray 22 and prevent the tray 22 from being heated, so that the grill can be used properly as a waterless grill.

In such a grill 200, when it is desired to see how the food F to be cooked in the grill storage 26 is burned, the grill storage 26 is provided through the viewing window 17 provided in the opening / closing door 16.

There is a disadvantage that it is difficult to perform, and since the front portion 110A of the top plate 110 protrudes above the viewing window 17, in order to firmly observe the food F, the line of sight is more than that of the front portion 110A of the top plate 110. They had to go down, which contributed to this drawback.

When the grill handle 15 is pulled out, the grill 21 and the pan 22 are simultaneously taken out of the grill chamber 26, and at the same time, the opening and closing door 16 is opened and closed in conjunction with the above. The combustion gas in the grill storage 26 leaks out of the gap 18 between the front panel and the opening / closing door 16, and there is a problem that heat efficiency and cooking performance deteriorate. Such an opening / closing door 16 is the receiving pan 2
In the case of the type that opens and closes in conjunction with pulling out 2, the gap 18 cannot be eliminated due to its structure. Particularly, in the grill which can perform the above-mentioned grilling, the presence of such a gap 18 has been a serious problem since the combustion gas trapped in the grill storage 26 leaks out. Further, since the front portion 110A of the top plate 110 is heated by the combustion gas leaked from the gap 18, the front portion 110A of the top plate 110 may be burned when touching the front portion 110A during use of the grill.

A handle for removal may be provided in the viewing window 47.
Through this viewing window 47, the cooking status of the cooking object F during the heating cooking can be confirmed. With such a configuration, the combustion gas does not leak from the front side of the grill storage 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 notch 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 storage 2
Since the lighting inside 6 can be obtained sufficiently, the grill storage 26
Inside is easy to see.

Next, the operation of the grill 20 will be described.
When the operation button 12c is pressed to the full, gas is supplied to the grill burner 27, and is ignited directly by a continuous spark from an electrode (not shown) to start combustion. Since the generated combustion gas is high in temperature, as shown by the dashed 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, and the upper exhaust port 32 It is discharged to the outside from 31.

Accordingly, the object to be cooked F is heated by the high-temperature combustion gas accumulated in the upper portion of the grill storage 26, so that heat energy can be effectively used, gas consumption is small, and energy is saved. Further, since the airtightness of the front side of the grill storage 26 is maintained, the combustion gas does not leak wastefully from the front side of the grill storage 26, and all the combustion gas passes through the exhaust chamber 32 and the exhaust port 31. , The object to be cooked F can be cooked more efficiently. The object to be cooked F
When the grill door 42 is opened to perform the return, etc., unlike the conventional grill, the viewing window 47 does not open in conjunction with the conventional grill, so that the amount of leaked combustion gas can be suppressed, and the 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 the grill 21 in and out is provided below the grill burner 27, the grill door 42 is opened and the grill When the 21 is pulled out from the grill chamber 26, the high-temperature combustion gas trapped in the upper part of the chamber is unlikely to overflow from the door opening 41,
The temperature drop in the cooking cabinet can be reduced, and when the grill 21 is pushed into the grill cooking cabinet 26 again, cooking is immediately resumed at a cooking cabinet temperature suitable for heating and cooking the object to be cooked F, thereby further improving thermal efficiency. The gas consumption can also be reduced.

Further, since there is no gap between the viewing window 47 and the front panel 45 which existed in the conventional grill, the combustion gas trapped above the grill storage 26 is subjected to combustion gas.
The front portion 11A of the top plate 11 is not heated by the high-temperature combustion gas because the front portion 11A does not leak from the front side. For this reason, even if the user touches the front portion 11A of the top plate 11 while using the grill 20, there is no fear of burns or the like.

Further, the heating of the cooking object F placed in the center portion, which is far from the grill burner 27 and receives little heat due to radiant heat, is supplemented by the convection of the combustion gas, so that the entire cooking object F is more uniformly burned. . Moreover, since the grill top plate 25 is formed in a V-shape, the combustion gas can be more effectively collected at the central portion as shown by the dashed arrow in the figure, and can be heated more uniformly.

In such grilled cooking, when the combustion gas fills the inside of the grill chamber 26 and overflows from the communication port 34, 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 is generated between the exhaust chamber 32 and the outside, and a sufficient upward draft force is generated in the exhaust chamber 32. With this sufficient drafting force, the combustion gas is smoothly discharged to the outside of the grill through the exhaust chamber 32, and external air is sucked into the cooling passage 23 from the air inlet 24 on the bottom of the grill warehouse 26, and is discharged to the lower surface of the pan 22. It flows along and cools the pan 22. Thus, the grill is
It can be properly used as a waterless grill that does not fill with water, and the object to be cooked F can be roasted.

Further, even if the grilled burner G and the dried food F are overheated due to forgetting to extinguish the fire of the grill burner 27, etc. Is provided, the flame is blocked by the flame shield device 35 and does not overflow from the exhaust port 31 to the outside of the body, which is extremely safe.

When observing the degree of burning of the cooking object F during the heating cooking through the viewing window 47, the lighting into the grill storage 26 is not blocked by the front portion 11A of the top plate 11, but more. Therefore, the object F to be cooked in the grill storage 26 can be well observed, and the depth of the grill storage 26 can be observed. Moreover, since it is not necessary to bother to look inside the grill storage 26 from below the front portion 11A of the top plate 11, the user must be in a mid-rear posture when observing the interior of the grill storage 26, but the degree of the conventional It can be reduced compared to.

Further, since the viewing window 47 can be removed by putting a hand into the grill storage 26 through the door opening 41 and pushing it from the inside of the grill storage 26, cleaning of the viewing window 47 itself and the interior of the grill storage 26 can be performed. Viewing window 4
7 can be maintained neatly, and the inside of the grill storage 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 at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. is there.

[0031]

As described in detail above, according to the stove with grill of the present invention, since the combustion gas does not leak out from the gap unnecessarily, the heat energy by the combustion of the fuel gas is used to heat and cook the object to be cooked. You can use it effectively. Further, since the viewing window does not open and close in conjunction with the opening and closing door, the amount of combustion gas leaking when the opening and closing door is opened can be suppressed, and heat energy can be used more effectively. In addition, since the combustion gas in the grill chamber does not leak from the front portion of the grill, the front portion of the top plate is not heated by the leaked combustion gas. Safe to touch.
In addition, since the viewing window can be removed, it is easy to clean the viewing window itself and the inside of the grill storage, so that the viewing window can be kept clean and the interior of the grill storage can be easily viewed forever. In addition, the lighting inside the grill storage is not blocked by the top plate, and more lighting is obtained,
It is possible to observe the cooking object in the grill storage well, and to be able to observe deep into the grill storage. Moreover, since there is no need to bother to look inside the grill storage from below the top plate, the user must be in a mid-lumbar posture when observing the interior of the grill storage, but the degree can be reduced as compared with the conventional one.

Further, according to the cooking stove with the grill according to the second aspect of the present invention, since the combustion gas trapped inside the grill storage does not leak out from the gap unnecessarily, it is particularly applied to a grill which can be grilled. In that case, the advantages can be fully exhibited. In addition, even when the open / close door is opened to return the food to be cooked, etc., the viewing window does not open in conjunction with it, so the amount of combustion gas that leaks out can be suppressed, further enhancing We can show advantage.
