  • Magnetron 16 an electric circuit including electronic components connected to latch switch unit 8, heat insulation plate 20, and damper unit 5 are disposed on the cooling passage.
  • heating cooker 50 of the present embodiment configured as described above, unpleasant sound and vibration generated during the closing operation of door 3 can be reliably reduced and even in a state where the disposition space and the disposition position are limited, easy action can be performed.
  • the heating cooker 50 of the embodiment in the closed state of door 3, there is a configuration in which penetration of moisture or the like into the inside portion of the casing via damper opening 10a of abutment end 14a of damper unit 5 is prevented. Therefore, the heating cooker 50 of the embodiment has an excellent operability, high safety, high reliability, and a small size.
  • the heating cooker since it is necessary to have a multifunctional high function and a small size and furthermore, there is a high heat region, there is a problem that the component disposition is greatly limited.
  • the heating cooker of the present disclosure by providing a small-sized damper unit having a splash-proof and dust-proof effect and high placement tolerance with a simple configuration, a small-sized and highly reliable heating cooker can be configured.
  • the heating cooker of the present disclosure unpleasant sound generated during the closing operation of the door can be reliably reduced, vibrations during the closing operation of the door can be suppressed, easy action with respect to the limitation of the disposition space and the disposition position can be performed and further, penetration of foreign matter into the inside portion of the casing can be prevented. Therefore, the heating cooker of the present disclosure is a small-sized heating cooker with high reliability, which has an operability by the user.
  • the present disclosure configurations that can reduce unpleasant sound generated during the closing operation of the door, suppress vibrations during the closing operation of the door, and perform easy action with respect to the limitation of the disposition space and the disposition position are provided, and thus special effects that have excellent operability by the user and have high reliability are obtained. Therefore, since the present disclosure can be applied to various heating cookers including a microwave oven which is a microwave heating apparatus and a small-sized and highly reliable heating cooker can be provided on the market, the heating cooker of the present disclosure is useful.
