Therefore, circular downward convex shapes 38a and 38b projecting downward from the bottom surface 31 are provided so as not to deteriorate the balance when placed on a flat surface.

  As shown in FIGS. 8 and 9, the grill 60 includes a frame body 61, placement parts 62 a to 62 n, and shift prevention parts 63 a and 63 b. When the grill net 60 is viewed from above, as shown in FIG. 9, it has a rectangular shape that is long in the front-rear direction, and the placing portions 62 a to 62 n are arranged in parallel with the first straight portion 61 a provided in the frame body 61. It is welded and fixed at a constant interval so as to connect the second straight portions 61b.

Further, a slip prevention part 63a is placed on the front side of the placement part 62a, and a slip prevention part 63b is placed on the rear side of the placement part 62n so as to connect the first straight part 61a and the second straight part 61b. It is welded and fixed so as to protrude upward from the portions 62a to 62n.

  The first straight portion 61a and the second straight portion 61b are bent downward on the front side and the rear side. The shape seen from the front side and the shape seen from the rear side are the same shape, and although the central part is lifted up slightly, leg portions 61c and 61d having a substantially U shape are formed.

  The grill 60 is arranged such that the leg portion 61c is positioned between the positioning convex portions 39a, 39b provided on the front side of the bottom surface 31 of the tray 30 and the front side wall 32a, and the leg portion 61d is provided on the rear side. The positioning projections 39c, 39d and the rear side wall 32b are disposed so as to be positioned when placed on the tray 30.

The frame 61 is formed of a single steel wire, and there is a joint portion 61e that is welded and joined to both ends of the steel wire at the substantially lower center of the leg portion 61c. The leg portion 61 c comes into contact with the saucer 30 when it is placed on the saucer 30, but the joint portion 61 e is located at a location that is slightly raised above the location that comes into contact with the saucer 30.

In the case of butt joining, the joint location may be slightly shifted and a step may be formed. However, since the joining portion 61e is located at a location that is slightly lifted above the location that contacts the tray 30, it does not rattle or damage the tray due to the level difference.

Also, if the first straight portion 61a and the second straight portion 61b have the joint portion 61e, the appearance is not good, but it is difficult to notice because it is located below the leg portion 61c, and the appearance impression Is hard to be damaged.
In the first embodiment of the present invention, the frame 61 is described as an example in which the steel frame 61 is configured by one steel wire and joined at one location. However, the frame body 61 is configured by two steel wires and is joined at two locations. In this case, in addition to the joint portion 61e of the leg portion 61c, the joint portion may be provided at a location slightly raised above the location where the leg portion 61d contacts the tray 30.

As described above, the grill net 60 is formed with U-shaped leg portions 61c and 61d on the front side and the rear side, so that a heavy cooking object 90 such as a pan is placed as shown in FIG. Even if it is placed, it can receive the load firmly in the front and rear, so that the grill 60 does not deform.

Moreover, since the leg parts 61c and 61d are U-shaped, it is difficult to obstruct the path of the hot air supplied from the back outlet 19 into the heating chamber 9, and the hot air is smoothly placed on the mounting parts 62a to 62d. The air is blown below 62n and inside the saucer 30, and does not adversely affect cooking.

Furthermore, even if the to-be-cooked object 90 which slides like a pan is mounted and it accommodates in the heating cabinet 9, or it pulls out from the heating cabinet 9, it protrudes upwards rather than the mounting parts 62a-62n. The to-be-cooked object 90 is not greatly displaced by the anti-displacement members 63a and 63b that are fixed to each other, so that cooking is not hindered.

Then, since the front and rear of the grill net 60 are the same shape, the front and rear may be facing either side when placed on the saucer 30, and it is not necessary to pay attention to the direction, so that the usability is good. In addition, the grill 60 has the same shape at the front and back, is easy to hold and has good cleaning properties, and therefore is less likely to be deformed when washed.

  The flow of hot air in the heating chamber 9 will be described in detail based on the structure of the grill 60 and the tray 30. The air sucked into the fan / heater chamber 28 is heated by the hot air circulation heater 21 to be heated in the fan / heater chamber. It becomes hot air while passing through 28.

Further, the rear outlet 19 and the air direction members 19 a to 19 d are provided at a position lower than the front side wall 32 a of the tray 30. In other words, the front side wall 32a is higher than the rear outlet 19 and the air direction members 19a to 19d.

Therefore, it is difficult for hot air to directly hit the door body 7, and as shown in FIG. 6A, the door 7 is provided at a position lower than the height of the highest position of the handle 7a than the height to the front side wall 32a. Further, the temperature rise of the handle portion 71 of the handle 7a is suppressed.

Then, the upper airflow direction member 19a provided above the rear outlet 19 projects forward from the rear side wall 32b of the tray 30 as shown in FIGS. 3 and 6B. Further, the upper wind direction member 19a protrudes to the front side of the lower wind direction member 19b, and is inclined from the middle toward the bottom surface 31 of the tray 30 so that the hot air surely enters the space between the grill 60 and the tray 30. It comes to flow.

  The hot air that has flowed into the space between the grill 60 and the tray 30 flows forward as shown in FIG. 10A while heating the lower surface side of the cooking object placed on the grill 60. The rear outlet 19 is at a lower position than the front side wall 32a, and further flows toward the bottom surface 31 by the upper wind direction member 19a, so that the hot air flows smoothly along the front side wall 32a above the heating chamber 9.

  Since the left side wall 32c and the right side wall 32d are inclined so as to rise from the rear to the front as described above, the hot air flowing in the side surface direction is also moved outward by the side walls as shown in FIG. It passes through the saucer 30 on which the grill 60 is placed without spreading, flows forward while heating the lower surface side of the food placed on the grill 60, and smoothly along the front side wall 32a. It comes to flow above the heating chamber 9.

Therefore, the hot air that has flowed smoothly above the heating chamber 9 reaches the circulating-air intake port 15, passes through the upper surface duct 17 a, and passes through the rear duct 17 b and is provided on the rear surface intake port 18 provided on the rear surface of the heating chamber 9. It is sent to the fan / heater chamber 28 through the fan case intake port 24a that communicates with the fan case, and smoothly circulates, so that the food to be cooked is evenly cooked and the cooking finish is improved.

  As described above, according to the heating cooker according to the first embodiment of the present invention, the U-shaped legs are formed on the front side and the rear side of the grill net, so that a heavy object to be cooked is placed thereon. However, it is possible to receive the load firmly in the front and back, the grill does not deform, and the user does not have to worry about placing the food to be cooked, so that the usability is improved.
