Burners 2 provided on the left and right side surfaces of grill storage 12
Reference numeral 0 denotes an all-primary-air burner having a combustion surface formed by penetrating a large number of small flame openings in a plane plate of porous ceramics and inhaling most of air required for combustion as primary air. An ignition electrode (not shown) is provided facing the burner 20.

An exhaust chamber 50 is provided at the back of the grill chamber 12 through a partition wall 52, and a communication port 54 which opens to the partition wall 52 and communicates the grill chamber 12 and the exhaust chamber 50 is provided with a grill 22. It is provided below. Therefore, the exhaust path is configured so that the combustion exhaust gas generated from the burner 20 is discharged from the exhaust port 51 through the exhaust chamber 50.

At the front center of the top plate 10, a rectangular upper window hole 10a for confirming an object F to be cooked in the grill storage 12 is opened. A grill top plate 30 serving as a ceiling of the grill storage 12 has an upper window hole 1 facing the upper window hole 10a.
A rectangular lower window hole 30a slightly smaller than 0a is opened. Between the top plate 10 and the grill top plate 30,
A heat insulating material 33 is provided around the lower window hole 30a to prevent the juice spilled out from the cooking pot from the cooking stove from entering the gap.
The heating to 0 is suppressed.

On top of the upper window 10a, the upper window 10
A viewing window 40 made of heat-resistant glass having a rectangular shape larger than a is provided. This viewing window 40 has a window handle 3 at the rear.
4 is fitted into a frame 35 provided with the same. A packing 32 is provided on the outer periphery of the frame 35 to fill a gap between the upper window 10a and the frame 35, and the viewing window 40 is configured to be detachable from the upper window 10a. A superhydrophilic photocatalyst combining a titanium oxide (TiO ₂ ) photocatalyst with an appropriate composition is formed on both upper and lower surfaces of the viewing window 40.

A shutter 41 is provided below the viewing window 40 to isolate the inside of the grill storage 12 from the viewing window 40.
The left and right ends of the shutter 41 are supported by a guide 31 having an L-shaped front section welded to the grill top plate 30,
It is provided so as to be slidable in the front-rear direction. Also, shutter 4
Spring hook 41a opened to the left and right in front of 1 and grill storage 1
2 The tension spring 42 is locked to the upper part of the front surface, and the shutter 41 is urged in the forward direction (forward).

The rear part of the shutter 41 is connected to a piano wire 43. As shown in FIG. 3, the piano wire 43 is connected to an upper roller 44 provided at the center of the back side of the grill storage 12.
And a lower roller 45 provided on the bottom surface on the center rear side of the grill storage 12, and the tip thereof is connected to one end (rear side) of a lever 47 provided below the bottom surface of the grill storage 12.
The lower roller 45 is configured to rotate left and right around a shaft 46 fixedly provided on the bottom surface of the grill storage 12 and change its direction freely. The lever 47 is rotatably provided around a fulcrum 49 provided on the bottom surface of the grill storage 12, and its tip projects to the front right side of the body, and is fitted with an opening / closing knob 48.

Therefore, the lever 47 is connected to the extension spring 42.
3 is urged in the clockwise direction in FIG. 3 via the piano wire 43 by the pulling force, and reaches a closed position (left) where it comes into contact with a stopper (not shown) and stops. When the opening / closing knob 48 is turned to the open position (right), the rear end of the lever 47 turns left, moves away from the lower roller 45, pulls the piano wire 43, and slides the shutter 41 in the rear direction. As a result, the shutter 41 is located below the grill top plate 30 (back side).
Then, the viewing window 40 appears, and light enters into the grill storage 12, so that the inside of the grill storage 12 can be checked well to the back of the grill storage 12.

According to the grill 1 described above, the operation buttons 7
When 1c is pressed, an on-off valve for opening and closing a gas flow path to the burner 20 is opened, fuel gas is ejected from the burner 20, and ignition is performed by continuous discharge of an ignition electrode.

The high-temperature combustion exhaust gas generated by the burner 20 during cooking temporarily accumulates in the upper part of the grill storage 12 and communicates with the communication port 5.
4 and is discharged through the exhaust chamber 50. Therefore, the food F is heated by the radiant heat and the retained exhaust heat, and the food F is efficiently cooked.

Normally, since the opening / closing knob 48 is in the closed position and the shutter 41 is closed, the food F
The baked fat G and oil smoke do not adhere to the viewing window 40. When it is desired to check the state of cooking, the user can open the shutter 41 by operating the opening / closing knob 48 to the open position to look inside the grill storage 12. After confirmation, open / close knob 48
When the user releases his / her hand, the urging force of the tension spring 42 automatically returns to the closed position, thereby closing the shutter 41 and preventing the viewing window 40 from being stained with oil again. Therefore, as long as the opening / closing knob 48 is not operated, the shutter 41 is always closed by the urging force of the tension spring 42, thereby preventing forgetting to close.

After cooking, if the viewing window 40 becomes dirty, the user grasps the window handle 34, removes the viewing window 40 from the body, and rinses with water. At this time, dirt can be easily washed away by the superhydrophilic photocatalyst formed in the viewing window 40.

Generally, when light is applied to a semiconductor serving as a photocatalyst, electrons existing in the valence band jump over the band gap and move to the conduction band. At this time, holes are formed in the valence band where electrons have disappeared, and an oxidation reaction occurs. One conduction band contains electrons and a reduction reaction occurs. The titanium oxide photocatalyst of the present embodiment has a strong oxidizing power and oxidizes water called adsorption water present on the surface of titanium oxide by holes,
Hydroxy radicals (.OH), which have very strong oxidizing power, are generated to decompose organic compounds and turn them into harmless substances such as carbon dioxide and water.

As described above, the titanium oxide photocatalyst causes an oxidation reaction when irradiated with light such as sunlight or a fluorescent lamp, and decomposes dirt (organic compound) attached to the viewing window 40 to secure a view. The degree of burning of the article to be cooked F can be confirmed well. Moreover, since the shutter 41 is normally closed and the degree of contamination of the viewing window 40 is reduced, the decomposition reaction by the photocatalyst works effectively. That is, shutter 4
Due to the synergistic effect of protection by 1 and decomposition by photocatalyst,
The visibility of the viewing window 40 is improved, and the degree of burning of the object to be cooked F can be more properly confirmed.

Further, the photocatalyst of the present embodiment has a feature of being superhydrophilic, and when irradiated with ultraviolet rays, the contact angle with water is reduced from tens of degrees or more to 0 degrees, and water is not repelled at all. Therefore, immediately after the burner 20 is ignited, the water vapor in the grill storage 12 is cooled on the surface of the viewing window 40 and countless water droplets are formed, thereby preventing fogging. In other words, water droplets are not formed on the superhydrophilized surface and a uniform water film is formed, so that it is possible to prevent the occurrence of fogging.
And the position of the object F to be cooked can be confirmed. The turning window 61a of the opening / closing door 61 may be similarly surface-treated with a superhydrophilic photocatalyst to prevent the occurrence of fogging.

Since the superhydrophilic surface has a higher affinity for water than oil stains, even if oil adheres to the viewing window 40, it can be easily separated by merely putting it in water. Dirt can be removed. Accordingly, only washing with water is required without using a detergent, which prevents a user from getting rough and does not pollute a river.

Since this superhydrophilic photocatalyst is treated on both the upper and lower surfaces of the viewing window 40, dirt from the grill storage 12 (lower surface) and dirt from the cooking pot by spilling (upper surface).
Is easy to drop.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and it is needless to say that the present invention can be carried out in various modes without departing from the gist of the present invention. is there. For example, in the present embodiment, a description has been given of a single-sided grill, but the present invention may be applied to a double-sided grill provided with burners above and below a grill. Further, a burner may be provided on an upper portion such as a ceiling surface of a grill storage. Also, the configuration may be such that the viewing window is not detached from the grill storage. Further, the surface of the viewing window may be treated with a fluororesin. In this case, the water repellency of the fluororesin makes it easier for the dirt to be repelled, and the dirt is less likely to adhere to the viewing window. Further, the dirt can be easily removed, and the degree of burning of the food can be confirmed well. . Further, the product cost may be reduced without performing surface treatment on the viewing window.
