A rack 17 is provided in the center lower surface of the moving table 12 in the loading / unloading direction, and a pinion 18 is engaged with the rack 17. The pinion 18 is fixed to a rotating shaft (power transmission shaft) 19. One end of the rotating shaft 19 is rotatably supported by a bracket 20 provided on the grill warehouse bottom base 13, and the other end is grill grill bottom base 13. It is rotatably supported on one side wall.

  A flat L-shaped bracket 22 is provided on the outside of the side wall of the grill warehouse bottom base 13 on which the other end of the rotary shaft 19 is rotatably supported. (For example, a DC motor with a brake) 23 is attached. A worm wheel 25 is attached to the other end of the rotary shaft 19 via a heat insulating torque limiter 24, and the worm wheel 25 meshes with a worm gear 26 attached to the rotary shaft of the motor 23. . The heat insulation torque limiter 24 includes a limiter constituent member 24a, a limiter constituent member 24b, and a compression spring member 24c. The end faces of the limiter constituting member 24a and the limiter constituting member 24b are arranged so as to face each other, and an uneven surface is formed on each of the facing faces. The compression spring member 24c is engaged with the outer periphery of one end of the limiter constituting member 24b, and presses the limiter constituting member 24b toward the limiter constituting member 24a with a predetermined elastic force.

  At least one of the limiter constituting member 24a and the limiter constituting member 24b constituting the heat insulating torque limiter 24 is made of a heat insulating material having a low thermal conductivity such as a heat resistant resin, and the uneven surface formed on the surfaces facing each other is, for example, The rotation torque below a predetermined value is transmitted from one side to the other. The limiter component 24b resists the elastic force of the compression spring member 24c when the rotation torque exceeds the predetermined value. The projections move in the directions, and the concave and convex surfaces are disengaged from each other, so that torque exceeding the predetermined value is not transmitted. Further, as described above, since at least one of the limiter component 24a and the limiter component 24b is made of a heat insulating material, the heat from the grill 11 transmitted through the rotary shaft 19 is insulated by the heat insulation torque limiter 24, It is prevented from being transmitted to the rotating shaft of the motor 23 via the worm wheel 25 and the worm gear 26. Further, since the heat insulating plate 21 is interposed between the outside of the side wall of the grill warehouse bottom base 13 and the bracket 22 as described above, the heat of the grill warehouse bottom base 13 is not transmitted to the motor 23 through the bracket 22. ing.

That is, the door holding shaft 28, the bracket 29, and the door holding shaft guide block 30 constitute an interlocking mechanism that moves the door 27 in conjunction with the moving table 12.

  When the moving table 12 is moved in the loading / unloading direction by the moving table driving mechanism, the door holding shaft 28 moves while sliding on the upper surface of the door holding shaft guide block 30, and as shown in FIG. When it moves in the drawing direction, the door holding shaft 28 rotates about a portion 28b parallel to the door 27, the portion 28d contacts the lower surface of the moving table 12, and the door 27 is lowered by a predetermined dimension. Thereby, the door 27 does not get in the way to put and remove cooked food (not shown) on the grill 16 on the tray 15 placed on the moving table 12, and the cooked food can be taken in and out. It becomes easy. Thus, the interlocking mechanism that moves the door 27 in conjunction with the moving table 12 also has a door lowering mechanism that lowers the predetermined dimension when the door 27 moves a predetermined amount in the pull-out direction.

  As shown in FIG. 7, the guide mechanism 14 is attached to the inner surfaces of both side walls of the grill warehouse bottom base 13. The guide mechanism 14 includes a slide rail 40 having a cross-sectional configuration as shown in FIG.

Rail. The intermediate rail 42 has a substantially C-shaped cross section having ball guide grooves (rolling grooves) 45, 45 in the longitudinal direction of the outer surface formed by curving upper and lower ends (both ends in the width direction) of the belt-shaped metal plate outwardly in an arc shape. This is a rail having a substantially I-shaped cross section formed by joining two rails 46 and the rear surfaces of the two rails 46 and 46 to each other. Similarly to the fixed rail 41, the moving rail 43 has a ball guide groove (rolling groove) in the longitudinal direction of the inner surface formed by bending the upper and lower ends (both ends in the width direction) of the belt-like metal plate in an inward arc shape. ) 47, 47 is a rail having a C-shaped cross section.

  The ball cage 48 is a plate-like body formed in a U-shaped cross section, and its upper and lower refracting edges are between the intermediate rail 42 and the ball guide grooves 45 and 44 of the upper and lower refracting edges of the fixed side rail 41, and the intermediate rail. Two are arranged so as to be positioned between the ball guide grooves 45 and 47 of the upper and lower refracting edges of the moving rail 43 and the plurality of balls 49 are rotatably held by the upper and lower refracting edges. Further, the ball cages 48 and 48 are moved between the intermediate rail 42 and the fixed rail 41 and between the intermediate rail 42 and the movable rail 43 as the intermediate rail 42 and the movable rail 43 move. ing.

  The guide mechanism 14 is configured such that the fixed rail 41 of the slide rail 40 is fixedly attached to the inner surfaces of both side walls of the grill warehouse bottom base 13 and the moving base 31 is attached to the moving rail 43. As shown in FIG. 8B, the moving base 31 includes a horizontal portion 31a, a vertical portion 31b that descends vertically from the edge of the horizontal portion 31a, and a side portion of the vertical portion 31b so as to cover the upper portion of the slide rail 40. The moving table holding part 31c which holds the end part of the moving table 12 formed in FIG. As shown in FIG. 9B, grooves 31d and 31e are provided at predetermined intervals on the side wall of the moving table holding portion 31c. The groove 31d is formed vertically, and the groove 31e is formed in an L shape in which the vertical portion and the horizontal portion communicate with each other. In addition, since the guide mechanism 14 covers the upper portion of the slide rail 40 with the horizontal portion 31a of the moving base 31, oil or the like released from cooked food such as fish and meat is prevented from entering the slide rail 40. it can.

  In order to mount the moving table 12 on the moving base 31, after inserting the support pin 12c into the groove 31d of the moving table holding portion 31c of the moving base 31, the moving table 12 is moved to the right in the drawing and FIG. As shown, the support pin 12c is inserted into the horizontal portion of the groove 31e, and then the moving table 12 is lowered so that the support pin 12b is inserted into the groove 31d. In order to remove the moving table 12 from the moving base 31, the front end of the moving table 12 is lifted up, the support pin 12b is removed from the groove 31d, the moving table 12 is moved to the left in the drawing, and the moving table 12 is further moved. This is done by lifting the rear end of the table 12c and allowing the table 12c to escape from the groove 31e.

  In the grill having the above configuration, when the motor 23 is started by operating a control means (not shown) and the motor 23 is rotated forward, the rotational force of the motor 23 is transmitted to the worm wheel 25 via the worm gear 26. The rotational force is converted into a linear motion force in the pulling direction of the moving table 12 via the heat insulating torque limiter 24, the rotating shaft 19, the pinion 18 and the rack 17, and the moving table 12 is pulled out from the opening of the grill box 11. . The door 27 attached to the door holding shaft 28 also moves in conjunction with the drawing movement of the moving table 12. When the movable table 12 reaches the vicinity of the drawer end point position, as shown in FIG. 6, the door holding shaft 28 rotates around the portion 28b supported by the bracket 29, and the door 27 is lowered by a predetermined dimension. The operation switch of the control means may be assigned to any of the switches SW1 to SW4 arranged on the front panel of the main grill 10.

  In this state, water is applied to the bottom of the tray 15 placed on the moving table 12, and cooked food (not shown) such as fish or meat is placed on the grill 16. Thereafter, when the control means is operated to start the motor 23 and reversely rotate the motor 23, the rotational force of the motor 23 is transmitted to the worm wheel 25 via the worm gear 26, and the rotational force is transmitted to the adiabatic torque limiter. 24, the rotary table 19, the pinion 18, and the rack 17 are converted into a linear motion force in the pull-in direction of the moving table 12, and the moving table 12 is pulled into the inside from the opening of the grill box 11. In conjunction with the movement of the moving table 12, the door holding shaft 28 is also pulled. At this time, since the door holding shaft 28 slides on the upper surface of the door holding shaft guide block 30, the door 27 gradually rises and coincides with the opening of the grill box 11 in the vicinity of the retracting end point of the moving table 12. The opening is closed with the door 27.

  After the moving table 12 is stored in the grill cabinet 11, heating means such as a grill burner (not shown) is activated to cook the cooked food. During this cooking, the inside of the grill cabinet 11 is heated to a high temperature, and the heat is transmitted to the outer wall of the grill cabinet 11. As described above, a heat insulating plate is provided between the outer wall of the grill cabinet bottom base 13 and the bracket 22. Since 21 is interposed, the heat of the outer wall is not transmitted to the motor 23 through the bracket 22. The heat in the grill 11 is transmitted to the rotary shaft 19 via the moving table 12, the rack 17 and the pinion 18, and at least one of the limiter component 24a and the limiter component 24b of the heat insulation torque limiter 24 is The heat is not transmitted to the motor 23 via the worm wheel 25 and the worm gear 26 because it is composed of a heat insulating member having a low thermal conductivity such as a heat resistant resin.

  Further, since the heat insulation torque limiter 24 is provided as described above, when the movement table 12 is blocked by an obstacle or the like, an excessive torque of the motor 23 is transmitted to the movement table 12 side through the rotary shaft 19. Even if the motor 23 stops due to a power failure or the like and does not rotate, the movable table 12 can be pulled out by manually pulling the door 27 (front plate) 27a and pulling it 27a.

  When the door 27, the moving table 12 and the door holding shaft 28 are to be removed and cleaned, the moving table 12 is pulled out to the pulling end point as shown in FIG. The support table 12b is lifted out of the groove 31d, the moving table 12 is moved leftward in the drawing, and the support table 12c is moved out of the groove 31e by lifting the rear end of the moving table 12. The door 27, the moving table 12, and the door holding shaft 28 can be integrally removed from the moving base 31.
