The lower main body side engaging portion 28 having the property sandwiches the lower door side engaging portion 27.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the user performs cooking by heating, the food is placed on the grill 13 in a state where the door 11 is opened and the tray 14 is pulled forward. Thereafter, the handle 17 is held and the door 11 is pushed in the direction of the entrance 16 to slide the tray 13 and insert the food into the cooking chamber 12. When the door 11 is continuously pushed, the upper packing 24 first hits the upper front surface of the inlet 16 as shown in FIG. In this state, the door 11 still remains inclined in the entrance direction due to the urging force of the holding means 18. When the door 11 is further pushed from this state, the door 11 starts to rotate around the insertion hole 23 and moves so that the door 11 becomes vertical against the urging force of the holding means 18. As a result, the position of the upper door side engaging portion 25 rises as the door 11 rotates and engages with the upper main body side engaging portion 26. At the same time, the lower door side engaging portion 27 provided at the lower portion of the door 11 approaches the lower main body side engaging portion 28 and engages with each other. Simultaneously with the above series of operations, as shown in FIG. 4, the inclined surface 29 provided at the lower portion of the door 11 rides on the support member 30 on the main body side, and the entire door 11 is pulled upward. As a result, the upper door side engaging portion 25 is raised, and thus is engaged with the upper main body side engaging portion 26 more deeply.

  When the user starts cooking while the door 11 is closed by the above operation, the air blower 8 rotates to cool the electronic components, and at the same time, the heater 15 is energized and becomes red hot. The cooked food in the cooking cabinet 12 is heated and cooked by the heating of the heater 15.

  By the way, at the time of such heating cooking, since the air blower 8 is rotating in the main body 1, the internal pressure of the cooking cabinet 12 is likely to increase due to the entry of air from the gap. In addition, when fish is being cooked, the internal pressure may increase suddenly, often due to rupture due to moisture expansion of the epidermis. In such a case, if the door 11 is not firmly closed, there may be a problem that smoke in the cabinet leaks from the gap between the door 11 and the main body 1.

  However, in the present embodiment, both the upper part and the lower part of the inlet 16 of the cooking cabinet 12 are securely closed by the closing means provided with the door 11 above and below, and even if the pressure in the cooking cabinet 12 rises, Even if the seal packing provided on the door is deteriorated or deformed during cleaning, smoke leakage from the gap between the door and the main body can be sufficiently suppressed. Further, this configuration can exhibit a sufficient effect even when the packing 24 is slightly deteriorated or deformed during cleaning.

  Further, in the present embodiment, when the door 11 is opened, the upper part is tilted in the direction of the inlet 16 and is rotated so that the door 11 becomes substantially vertical in conjunction with the closing operation of the lower closing means. Thus, the upper portion of the door 11 is engaged with the upper portion of the inlet 16, so that the upper and lower closing operations of the door 11 can be effectively combined at one time, and the operability of the door 11 is obtained.

  Further, in this embodiment, the upper portion of the door 11 is engaged with the upper portion of the inlet 16 by lifting the door 11 upward in conjunction with the closing operation of the lower closing means, so that the engagement portion of the engaging portion can be increased. And the closing effect is further improved.

  In the present embodiment, the lower closing means employs a configuration in which one of the springs sandwiches the other. However, for example, a configuration that pulls both together using a magnet may be used. A protrusion having a downward or upward convex shape provided in the lower portion may be fitted into a hole or a throttle portion provided on the main body side.

  As described above, the heating cooker according to the present invention reduces smoke leakage to the outside by improving the closed state of the door. For example, not only the heating cooker but also the entrance and the door It can also be applied to a door configuration such as a furnace having
