  First, as shown in FIGS. 3 and 5, the front side of the protruding portion 46 of the heating cooker 1 according to the present embodiment is a stepped space 55 that is cut out in a stepped manner. The front surface of the protrusion 46 is preferably closer to the cooking chamber 2 than the rotation center line C of the door 3.

  In addition, the door 101 of the substantially uniform thickness equivalent to the conventional heating cooker is shown with a dashed-two dotted line for the comparison with the heating cooker 1 which concerns on this embodiment. The lower end of the conventional door 101 is substantially uniformly thick and does not have the stepped space 55. Therefore, the lower end front edge 101a of the door 101 is located on the front side of the lower end front edge 46a of the protrusion 46 according to the present embodiment.

  Next, as shown in FIG. 6, the heating cooker 1 according to this embodiment is in the middle of opening the door 3 (and naturally during the closing), and the lower end front edge 46 a of the protruding portion 46 closes the door 3. The locus | trajectory which approaches the cooking chamber 2 without approaching the saucer 17 side from the position a is drawn (broken line in FIG. 6). In particular, when the position a (that is, the position of the front edge 46a at the lower end of the protrusion 46 when the door 3 is closed) is spaced approximately equal to the distance from the cooking chamber 2 to the rotation center line of the door 3. Alternatively, when the door 3 is closer to the cooking chamber 2 than the rotation center line of the door 3, the lower end front edge 46 a only moves away from the tray 17.

  On the other hand, the conventional heating cooker sinks downward from the initial position X when the lower edge front edge 101a of the door 101 closes the door 3 while the door 3 is being opened (and naturally when the door 3 is being closed). It cannot approach the side and collide with the tray 17 and avoid interference (two-dot chain line in FIG. 6). That is, in the conventional cooking device, it is necessary to secure a large gap with respect to the saucer 17 in consideration that the lower end front edge 101a of the door 101 is closer to the saucer 17 than the initial position X (a saucer indicated by a two-dot chain line). 102).

  In addition, even when the lower end front edge 46a is farther from the cooking chamber 2 than the rotation center of the door 3, the lower end front edge 46a is closer to the tray 17 than the lower end front edge 101a of the door 101 in the conventional cooking device, The amount of gap to be secured can be reduced.

  Moreover, the heating cooker 1 which concerns on this embodiment will flow out the water | moisture content which generate | occur | produced at the time of cooking and accumulated on the boundary of the heating chamber 2b and the door 3, if the door 3 is opened. In particular, moisture dripping on the inner surface of the door 3 (that is, the surface on the cooking chamber 2 side) reaches the lower end front edge 46a along the lower end rear edge of the protrusion 46. Moisture that reaches the lower end front edge 46a of the protrusion 46 is dropped from the lower end front edge 46a and received by the tray 17. (Dashed arrow D).

  Accordingly, the water accumulated in the heating chamber 2 b flows out of the heating chamber 2 b and reaches the tray 17, or drops from the door 3 to the front edge 46 a of the lower end of the protruding portion 46 and reaches the tray 17 to reach the tray 17. Does not leak. Further, the inner surface of the door 3 (that is, the surface on the cooking chamber 2 side) is substantially flat and prevents moisture from dripping, allowing the water to flow out smoothly.

  Next, as shown in FIG. 7, the heating cooker 1 according to the present embodiment turns the inner surface of the door 3 upward when the door 3 is fully opened. Although some water droplets remain on the inner surface of the door 3, it is flat up to the immediate vicinity of the cooking cabinet 2, so that it is easy to wipe off the remaining water.

  Therefore, the heating cooker 1 according to the present embodiment includes a protrusion 46 on the door 3, thereby providing a gap separating the door 3 (more specifically, the protrusion 46) and the tray 17 when the door 3 is closed. It is possible to make it as narrow as possible, and when the door 3 is fully open, the substantially flat inner surface of the door 3 can be revealed.

  In addition, the cooking device 1 according to the present embodiment includes the tray 17 positioned below the door 3 and the protruding portion 46, thereby reliably guiding the moisture accumulated in the heating chamber 2 b to the tray 17. Can do.

  Furthermore, the heating cooker 1 which concerns on this embodiment can discard the water | moisture content collected on the saucer 17 easily by providing the saucer holding | maintenance part 43 in the cooking chamber 2. FIG.

  Furthermore, the heating cooker 1 according to the present embodiment integrally forms the protruding portion 46 with the door 3, so that the door 3 (more specifically, the protruding portion 46) and the tray 17 are connected in a state where the door 3 is closed. The gap between them is as narrow as possible, and an impression that is continuously arranged can be given.

  Moreover, since the heating cooker 1 which concerns on this embodiment is making the protrusion part 46 hang down to the tray 7 side rather than the lower end of the outer box 6, shortening of the lower end part of the outer box 6, and the outer box 6 whole are small. The cost of the outer box 6 that generally uses a coated iron plate is reduced.

  Therefore, according to the heating cooker 1 according to the present embodiment, the moisture accumulated at the boundary between the door 3 and the heating chamber 2b is smoothly guided to the tray 17 so that the moisture is hardly left inside the door 3, and Whether the door 3 is opened or closed, it is possible to provide a clean appearance.
