(Embodiment 1)
FIG. 1 shows a detailed view of the cooking device according to the first embodiment of the present invention.

  In FIG. 1, a cooking chamber 12 that has a door 11 that opens and closes a front opening and that heats an object to be heated, a tray 13 that is stored in the cooking chamber, and a movable body that is linked to the tray 13. 14 and at least one pair of rails 15 that hold the movable body 14 and have a sliding portion that slides the movable body 14, and the rail 15 is connected to the end face side of the rail 15 by a connecting member 16. The connecting member 16 is brought into contact with an abutting surface formed in a cross section on the end surface side of the movable body 14 of the rail 15 and is provided at a predetermined distance away from the abutting surface on the side opposite to the end surface. The internal thread portion is tightened so that the tightening direction of the screw is along the length direction of the rail.

  About the structure regarding the door opening and closing of the heating cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  In order to smoothly open and close the door 11 of the heating cooker, it is necessary to slide the rail 15 smoothly. To smoothly slide the rail, the distance between the movable bodies 14 of at least one pair of rails is constant. And a mechanism for maintaining the parallelism of the at least one pair of rails with respect to the sliding portion of the movable body 14 is required (see FIG. 3). Therefore, the connecting member must abut at right angles to the sliding direction of the rail. That is, the contact surface formed by a cross section on the end surface side of the movable body 14 with which the connecting member 16 is contacted needs to be formed at right angles to the sliding direction of the rail 15. In the configuration according to the conventional invention, the contact surface is formed by processing such as bending. In bending, the degree of springback or the like varies depending on variations in the physical characteristics of the workpiece, so variations in processing accuracy such as flatness of the contact surface and perpendicularity to the sliding direction of the rail 15 are suppressed. It is hard to do. On the other hand, in the present invention, the contact surface is formed by a simple processing method such as cutting or cutting, and the processing accuracy such as the flatness of the contact surface and the perpendicularity to the sliding direction of the rail 15 is improved. The variation is less likely to occur compared to the configuration according to the conventional invention. Variation in perpendicularity of the contact surface with respect to the sliding direction of the rail 15 can be suppressed. Further, unlike the conventional configuration (see FIG. 7), the screw tightening direction is along the length direction of the rail in the female thread portion provided at a predetermined distance away from the end surface with respect to the contact surface. The rigidity of the joint between the connecting member and the rail can be increased by reducing the degree of freedom between the rail and restraining the connecting member at one point separated from the one plane by a predetermined distance. (See FIG. 8).

As described above, in the present embodiment, the connecting member 16 is brought into contact with the contact surface formed by the cross section on the end surface side of the movable body 14 of the rail 15, and the predetermined surface on the opposite side to the end surface with respect to the contact surface. By tightening the screw tightening direction so that the tightening direction of the screw is along the length direction of the rail, it is difficult to cause variations in processing, and the rigidity of the joint between the connecting member and the rail is sufficient. Therefore, deformation due to external force applied to the door at the time of opening / closing or assembling is difficult to occur. Therefore, the perpendicularity of the contact surface of the connecting member and the rail sliding direction can be easily maintained, and at least one pair of rail movable bodies 14 is provided. And the parallelism of the at least one pair of rails with respect to the sliding portion of the movable body 14 can be maintained, and a cooking device having a door that can be opened and closed smoothly can be obtained.

  By having the connecting member fixing component 17 attached to the tip of the movable body 14, it is easy to process the contact surface and the female screw portion that contact the movable body 14. Further, since the cross-sectional shape of the abutting surface that abuts the movable body 14 can be changed relatively freely, the rigidity of the joint portion is sufficiently high, and deformation due to an external force applied to the door at the time of opening / closing or assembling is difficult to occur. There is an advantage that it is easy to maintain the squareness of the contact surface of the connecting member and the rail sliding direction. In addition, even if the design of the door and the shape and size of the attachment portion are changed, there is an advantage that the other parts of the rail 15 can be shared without changing only by changing the shape of the connecting member fixing component 17. Further, by creating the shape of the connecting member fixing component 17 so that it can be incorporated into the shape of a commercially available rail, a member having a limited shape such as a commercially available rail can also be used. There is an advantage that the product can be made cheaper and have a higher commercial value. In this invention, it can be set as the heating cooker which has the door which can be opened and closed smoothly, and is excellent in assembling property and member workability.
