The grill box 11 has a substantially box-like shape, and a drawer-type grill door device 20 in which a grill tray is detachably mounted and is detachably accommodated in the grill chamber 11. Hereinafter, the grill unit 10 will be described with reference to FIGS. 2 to 6, the top plate of the grill chamber 11 is omitted (the same applies to the following drawings).

  The grill chamber 11 is formed by pressing a thin metal plate or joining the ends of the thin metal plate by welding or screws to form a substantially box shape. The front is open to the front side of the main body case 2. An opening 12 is provided, and an exhaust duct 13 that opens to an intake / exhaust port 6 provided in the top plate 3 of the main body case 2 is provided on the rear surface side.

  A pair of fixed guide rails 14a and 14b having a U-shaped cross section (only one of the fixed guide rails 14a is shown in the figure. In this description, it may be simply described as 14), but it is attached by screws, welding or the like with the openings facing each other. Although not shown, a heating element such as a sheathed heater or a halogen heater is disposed on the lower surface of the top plate of the grill chamber 11, and the upper surface of the bottom plate is maintained at a predetermined distance from the bottom plate. A heating body such as a sheathed heater that is horizontally deployed from the back surface to the front surface of the grill chamber 11 is disposed.

  The grill door device 20 has a pair of slide rails 23a and 23b (hereinafter referred to as the following) that are U-shaped in cross section and are connected to both sides of the rear surface of the grill door 21 via a pull-down mechanism 25 described later. The slide rails 23a and 23b are fitted on the outside of the fixed guide rails 14a and 14b provided in the grill chamber 11 so as to be slidable in the front-rear direction. The front and rear sides of the opposed slide rails 23a and 23b are formed in a frame shape by holding the connecting arms 24a and 24b for maintaining the distance between them and reinforcing them. When opening and closing 20, the cooked food placed on the grill pan 40 is not distorted due to the weight balance of the cooked food, and can operate smoothly.

In addition, the grill door device 20 is provided with a pull-down mechanism 25 so that when the grill door 21 is pulled out, the grill door 21 is lowered to make it easy to take out the grill pan 40 and the cooked food thereon. ing.
One end of the pull-down mechanism 25 is fixed to a pull-down connecting arm 33 (FIG. 4) provided on the back side of the grill door 21, and the other end is pivotally supported on the slide rails 23 a and 23 b by a connecting pin 27. The pull-down arms 26a and 26b (hereinafter sometimes simply referred to as 26), the substantially middle portion in the vertical direction is pivotally supported by the pins 31 on the slide rails 23a and 23b, and the lower portion is pulled down by the pull-down arms 26a and 26b. It consists of holding arms 30a and 30b (hereinafter simply referred to as 30) that are slidably connected via a pin 32 to a sliding hole 28 provided in the longitudinal direction of 26b.

  The grill pan 40 on which the food to be heated is placed and cooked is formed of a stainless steel plate or a highly corrosion-resistant metal plate having a surface subjected to enamel coating treatment. A flange 42 bent outward is provided at the upper end.

Next, the operation of the grill unit 10 according to the present embodiment configured as described above will be described.
As shown in FIG. 2 to FIG. 4, the flange 42 of the grill pan 40 on which the food to be heated (not shown) is placed on the dish portion 41 is placed on the slide rails 23 a and 23 b. Then, when the handle 22 is put in and the grill door device 20 is pushed into the grill chamber 11, the slide rails 23a and 23b move along the fixed rails 14a and 14b, and the grill door 21 closes the opening 12. The grill door device 20 and therefore the grill pan 40 are accommodated in the grill chamber 11.

  At this time, the pull-down arms 26a and 26b rotate about the connecting pin 27 and become substantially horizontal along the slide rails 23a and 23b, and the holding arms 30a and 30b also rotate about the pin 31. At the same time, the lower pin 32 moves to the front side in the sliding hole 28 and becomes substantially horizontal between the sliding rails 23a, 23b and the pull-down arms 26a, 26b, so that the grill door 21 is in the grill chamber 11. The opening 12 is closed. The state at this time is shown in FIG.

  In this state, power is supplied to the heating bodies provided at the top and bottom of the grill chamber 11, and the cooked food on the grill pan 40 is heated and cooked. At this time, steam and smoke generated by heating and cooking are discharged to the outside through the duct 13 through the intake / exhaust port 5.

  When cooking is finished, as shown in FIG. 5, the user holds the handle 22 of the grill door 21 and pulls out the grill door device 20 from the grill chamber 11. When the grill door 21 is pulled out to the maximum extent, the pull-down arms 26a and 26b rotate obliquely downward from the horizontal state around the connecting pin 27 as shown in FIG. Then, it becomes a pull-down state.

At the same time, the pin 32 provided at the lower part of the holding arms 30a and 30b and connected to the sliding hole 28 of the pull-down arms 26a and 26b moves to the rear end portion with the displacement of the sliding hole 28, and the holding arm 30a. , 30b are rotated. At this time, the pin 32 acts as a stopper for the pull-down arms 26a and 26b, and the pull-down arms 26a and 26b are held in that position and do not rotate any further.
Thereby, the grill door 21 is positioned obliquely downward with respect to the slide rails 23a and 23b.

  Further, when the holding arms 30a and 30b are in the pull-down state, the upper ends thereof protrude from the upper surfaces of the slide rails 23a and 23b. As a result, the grill door 21 tilts and the upper ends of the holding arms 30a and 30b push up the flange 42 of the grill pan 40 placed on the slide rails 23a and 23b. As described above, a gap is generated between the slide rails 23 a and 23 b and the flange 42. Therefore, the grill pan 40 on which the cooked food is placed can be easily lifted and removed by inserting a fingertip or a hook into the gap.

  In this way, the holding arms 30a and 30b rotate with the tilting of the pull-down arms 26a and 26b to lift the grill pan 40, so that the upper end of the holding arms 30a and 30b is obliquely chamfered or greased. By doing so, it can operate more smoothly.

  7 and 8 show another example of the grill unit 10 according to the present embodiment. In this example, the holding arms 30a and 30b are moved from the slide rails 23a and 23b when the holding arms 30a and 30b are in a horizontal state. As long as it does not protrude, the upper part is formed in a substantially T shape with a wide width, and the grill pan 40 is lifted in a balanced and stable manner.

According to the present embodiment, when the grill door device 20 is pulled out from the grill chamber 11, the grill door 21 tilts obliquely downward due to the pull-down, so that the height difference between the upper side of the grill door 21 and the grill tray 40 is reduced. It becomes easy to take out the grill pan 40 and the cooked food placed thereon.
Further, the upper ends of the holding arms 30a and 30b automatically lift the grill pan 40 by pull-down, and a gap is formed between the slide rails 23a and 23b, so that the grill pan 40 can be easily removed.

Furthermore, since the grill pan 40 has its flange 42 mounted on the slide rails 23a and 23b fitted outside the fixed guide rails 14a and 14b, the grill pan 40 is wide between the top plate and the grill pan. The width of 40 can be formed to be substantially equal to the width of the grill chamber 11, whereby the use space of the grill chamber 11 can be set to the maximum in the use of the grill unit 10.
For this reason, even a larger material than before can be cooked.
