[Configuration of damper unit 5]
FIG. 5 is a cross-sectional view showing the configuration of the damper unit 5. The damper unit 5 has a damper 12 having a shock absorbing tip 12a that contracts when it contacts the door 3 and absorbs the shock, and a damper holding part for holding the damper 12 and attaching it to the heat insulating plate 20 that is a heat insulating member. 13, and a damper cap 14 that is constantly pressed in a direction in contact with the door 3 by the shock absorbing tip 12 a of the damper 12.

  The damper cap 14 can come into contact with the door 3. When the door 3 is in the opened state, the damper cap 14 protrudes from the damper opening 10 a of the outer edge 10 of the heating chamber and the outer peripheral portion of the protruding base of the contact end 14 a. It has a flange part 14b formed so as to expand radially, and a sliding part 14c that slides along a linear groove formed in the damper holding part 13. The contact end 14a, the flange portion 14b, and the sliding portion 14c of the damper cap 14 are integrally formed by resin molding. The sliding portion 14c is formed in a groove formed in the damper holding portion 13 in association with the contraction operation of the shock absorbing tip portion 12a after the contact end 14a contacts the door 3 during the closing operation of the door 3. It is comprised so that it may slide linearly along. Also, a flange tip 14d is formed at the outer peripheral end of the flange 14b, and this flange tip 14d is the position of the front end of the sliding portion 14c. The damper cap 14 that is constantly pressed by the shock absorbing tip 12a of the damper 12 is formed with a pressing surface 14e. Is formed on the back side.

  The damper cap 14 configured as described above is configured to slide and move to the damper holding portion 13 along the front-rear direction of the heating chamber 2 (substantially pressing direction of the contact end 14a against the door 3). ing. The damper holding portion 13 is positioned in contact with the positioning protrusion 15 formed on the heat insulating plate 20 and is securely attached to a predetermined position of the heat insulating plate 20.

  The damper 12 used in the damper unit 5 in the first embodiment is an oil damper, and has a configuration in which the shock absorbing tip 12a moves in the contraction direction to attenuate the shock at the time of contact. In the present disclosure, an example in which an oil damper is used as the damper 12 will be described. However, the configuration of the present disclosure is not limited to the oil damper, and the door 3 and the contact end 14a are not in contact with each other. Any means may be used as long as it has a shock absorbing function for absorbing the shock and the door 3 slowly and smoothly shifts to the closed state, and is appropriately used in consideration of the specification and shape of the damper.

  As shown in FIG. 5, the damper cap 14 having the abutting end 14 a is constantly pressed by the shock absorbing tip 12 a of the damper 12, and in the opened state of the door 3, the heating that is the outer peripheral portion of the heating chamber opening 2 a. It contacts the inner surface of the outdoor edge 10. In the open state of the door 3, the flange tip 14 d formed at the front side end of the sliding portion 14 c of the damper cap 14 is in reliable contact with the inner surface of the heating chamber outer edge 10.

  As shown in FIG. 5, the damper opening 10 a formed at the outer edge 10 of the heating chamber and projecting the contact end 14 a of the damper cap 14 is formed by bending the edge portion inward. A flange portion 14b is formed so as to expand radially from the protruding root of the contact end 14a that can protrude from the damper opening 10a, and a flange tip 14d is formed on the outer peripheral edge of the flange portion 14b. Since the flange tip 14d protrudes in the direction of the inner surface of the heating chamber outer edge 10 where the damper opening 10a is formed, the damper cap 14 is pressed by the damper 12 when the door 3 is opened. The flange tip 14d is in reliable contact with the inner surface of the outer edge 10 of the heating chamber.

  As described above, in the opened state of the door 3, the flange tip 14 d reliably contacts the inner surface of the heating chamber outer edge 10, and the damper opening 10 a is closed by the flange 14 b. For this reason, it is prevented that the water | moisture content and foreign material by the vapor | steam from the heating chamber 2, etc. enter the inside of the heating chamber outer edge part 10 through the opening 10a for dampers, and especially the penetration | invasion to the damper unit 5 is prevented. Thus, in the opened state of the door 3, since the damper opening 10a is reliably closed by the flange 14b, the oil content in addition to the moisture that may reduce the function in the damper 12 that suppresses vibration, It is configured to reliably prevent entry of foreign matters such as dust.

  In addition, in the damper unit 5 in the heating cooker of Embodiment 1, the protrusion direction of the shock absorption front-end | tip part 12a of the damper 12 is a diagonally upward direction. The pressing surface 14e of the damper cap 14 that is constantly pressed by the shock absorbing tip 12a of the damper 12 is formed on a surface that is orthogonal to the protruding direction of the shock absorbing tip 12a. For this reason, the pressing surface 14e is a surface inclined with respect to the pressing direction (substantially horizontal direction) of the contact end 14a, which is the front-rear direction of the heating chamber 2 of the damper cap 14. That is, the pressing surface 14 e is formed on a surface that is oblique to the sliding direction of the damper cap 14. As described above, the pressing surface 14e of the damper cap 14 that is constantly pressed by the shock absorbing tip portion 12a is a surface orthogonal to the protruding direction of the shock absorbing tip portion 12a, and is skewed with respect to the pressing direction of the contact end 14a. By adopting such a surface, the tolerance of the arrangement position of the damper unit 5 can be increased while maintaining the shock absorbing ability of the damper 12. Note that, on the pressing surface 14e of the damper cap 14, a skew angle of ± 10 degrees is preferable with respect to the pressing direction (substantially horizontal direction) of the contact end 14a.

  FIG. 6 is a diagram illustrating a specific configuration of the damper unit 5 in the heating cooker according to the first embodiment. 6A is a front view, FIG. 6B is a top view, and FIG. 6C is a right side view. 6 (d) and 6 (e) are perspective views, FIG. 6 (d) is a diagram seen from the upper right side on the front side, and FIG. 6 (e) is a diagram seen from the upper side on the back side. is there.

  As shown in FIG. 6, the damper 12, the damper holding portion 13, and the damper cap 14 in the damper unit 5 are unitized and miniaturized, and can be easily attached to a desired position. Further, in the damper unit 5, the damper holding portion 13 attached to the heat insulating plate 20 is disposed between the damper 12 and the heat insulating plate 20, and the side surface portion of the damper 12 opposite to the heat insulating plate 20 is largely opened. In addition, the heat transfer from the heating chamber 2 is prevented, and cooling is reliably performed by the fan 17 (see FIG. 7) that is a cooling means that forms an air flow that flows along the heat insulating plate 20 that is a heat insulating member. It is configured to be.

It is the structure which can respond easily also in a state. In the first embodiment, when the door 3 is closed, moisture or the like is prevented from entering the housing through the damper opening 10a of the contact end 14a of the damper unit 5. Yes. Therefore, the heating cooker of Embodiment 1 is excellent in operability, and becomes a small heating cooker with high safety and reliability.

  As described above, the heating cooker has a problem that it is necessary to be multifunctional and highly functional and to be configured in a small size, and further, because there is a high heat region, the arrangement of parts is largely regulated. ing. However, in the cooking device of the present disclosure, a small and highly reliable cooking device is constructed by providing a small damper unit having a drip-proof and dust-proofing effect with a simple configuration and a high placement tolerance. It becomes possible.
