When the door 50 is closed by rotating around the hinge pins 57 and 58, the lock receiving portion on the side of the door 50 becomes the lock portion 17 of the housing 10. Lock to.

  In a state in which the door 50 is locked, the glass plate 53 provided on the back surface of the opening / closing door 50 covers the entire circumference in the frame of the support member 60 with respect to the packing 15 provided around the opening 11. The casing 10 can be sealed (held in an airtight state). The door 50 can be unlocked by operating the handle 51 in the unlocking direction.

  Further, a rotation restricting roller (an example of the “rotation restricting portion” of the present invention) 97 is provided on the free end side of the upper end surface of the opening / closing door 50 via a mounting plate (corresponding to “attaching member” of the present invention) 55. It is attached. As shown in FIGS. 3 and 6, the mounting plate 55 extends from the upper end surface of the opening / closing door 50 to the back side (Z direction) of the housing 10, and is adjacent to the plate flange 64 on the left and right in the X direction. It has become a relationship. And the rotation control roller 97 is being fixed to the back surface side of the attachment plate front-end | tip. The rotation restricting roller 97 is engaged with the guide groove 82 to restrict the opening / closing door 50 from opening any more when the opening / closing door 50 rotates to the limit angle θ from the unlocked state. .

  Specifically, as shown in FIG. 5, a roller introducing portion 85 is provided at the start end portion of the guide groove 82. The roller introducing portion 85 is provided between the outer peripheral plate 83 and the inner peripheral plate 84 and extends in an arc shape from the starting end of the guide groove 82 toward the rear side (Z direction) of the housing 10. As shown in FIG. 5, the roller introduction portion 85 has a circular arc shape on the outer peripheral side and a tapered shape on the inner peripheral side, the rear end portion 85A is narrow, and the width of the central portion is wide.

  When the door 50 is locked, the rotation restricting roller 97 is positioned at the rear end portion 85A of the roller introducing portion 85 as shown in FIGS. After unlocking, when the handle 51 is pulled to the front right, the open / close door 50 rotates about the hinge pins 57 and 58 while sliding to the right together with the support member 60. As a result, the rotation restricting roller 97 moves along the roller introducing portion 85.

  When the opening / closing door 50 rotates to the limit angle θ, as shown in FIGS. 7 and 9, the rotation restricting roller 97 moves from the roller introduction portion 85 to the entrance portion of the guide groove 82, and enters the groove of the guide groove 82. To fit. The rotation restricting roller 97 fitted in the guide groove 82 can only move in the horizontal direction, and cannot move in any other direction. Therefore, the rotation of the opening / closing door 50 can be restricted. In this example, the limit angle θ of the open / close door 50 is “10 °”, but the limit angle θ is preferably “20 °” or less.

  After that, as shown in FIG. 10, the opening 51 formed on the front surface of the housing 10 is opened by further pulling the handle 51 and sliding the entire support member 60 including the open / close door 50 to the right. I can do it. Therefore, a cooking object such as a food can be taken in and out of the cooking chamber 20A inside the housing through the opening 12.

  Further, when closing the door 50, pulling the handle 51 in the reverse direction and sliding the entire support member 60 including the door 50 leftward, the rotation restricting roller 97 eventually introduces the roller from the guide groove 82. Move to section 85. After the rotation restricting roller 97 moves to the roller introducing portion 85, the rotation restricting roller 97 moves back along the arc of the roller introducing portion 85, so that the open / close door 50 is closed with the hinge pins 57 and 58 as the shaft while sliding in the horizontal direction. Rotate in the direction.

  When the entire support member 60 including the opening / closing door 50 moves to the closing position at the stroke end, when the opening / closing door 50 is pushed back through the handle 51, the lock receiving portion of the opening / closing door 50 is moved to the housing 10. Lock to the lock unit 17.

  Thus, the steam convection oven M has a structure that opens and closes the opening / closing door 50 by a combined operation of rotation and sliding, and is a structure that restricts the opening angle of the opening / closing door 50 to the limit angle θ. Therefore, as shown in FIG. 11, it is possible to reduce the occupation area of the opening / closing door 50 (D dimension part shown in FIG. 11) when the door is opened, and the door does not block the passage. In addition, the mark in FIG. 11 has shown the cooking worker.

  As shown in FIG. 4, the mounting plate 55 is attached to the upper end surface of the door 50 through a hinge (hinge plate) 56, and the vertical direction about the hinge shaft 56A of the hinge 56 (the present invention). In the “dissociation direction”). Therefore, when the mounting plate 55 is flipped upward as shown in FIG. 12, the rotation regulating roller 97 fixed to the tip of the mounting plate 55 can be removed from the roller introducing portion 85 and the guide groove 82. When the rotation restricting roller 97 is removed, the free end side of the opening / closing door 50 is in a free state, so that the opening / closing door 50 can be rotated more than the limit angle as shown in FIG. By doing in this way, there exists an advantage that it becomes easy to perform the maintenance operation | work of the door 50. FIG.

3. Explanation of Effects As described above, the steam convection oven M can be used widely in the kitchen passage because the opening / closing door 50 does not block the passage when the opening / closing door 50 is opened, and the workability is good. In addition, since the opening / closing door 50 is configured to slide horizontally along the front surface of the housing 10, it is easy to open and close the door. In addition, since the entire support member 60 including the open / close door 50 is slid, the open / close door 50 is difficult to tilt and the operation is stable when sliding.

  The steam convection oven M has a structure that restricts the opening angle of the opening / closing door 50 to the limit angle θ by fitting the rotation restricting roller 97 into the guide groove 82 that guides the sliding operation of the opening / closing door 50. In other words, the guide groove 82 has a structure that serves both as a slide function guide function and an opening angle regulating function. Therefore, it is not necessary to provide a dedicated member for restricting the movement of the rotation restricting roller 97, so that the number of parts can be reduced, and the configuration of the apparatus can be simplified.

  Further, since the steam convection oven M is provided with the roller introducing portion 85 at the start end portion of the guide groove 82, the rotation restricting roller 97 can be smoothly introduced into the guide groove 82.
