The door cover side water droplet guide portion 33 has a curved surface 33a having a curvature from the main body 10 side (rear side) toward the front side (front side) of the door 11. The door cover-side water droplet guide portion 33 has a dimension such that an extension line of the curved surface 33 a intersects the door-side water droplet guide portion 31.

  The surface on the main body 10 side of the door cover-side water droplet guide portion 33 is not limited to a curved surface, and may be formed by a straight line inclined from the main body 10 side to the front side of the door 11. In this case, the straight extension line is set so as to intersect the door-side water droplet guide part 31.

  The end portion of the door-side water droplet guide portion 31 is formed to be longer downward than the end portion of the door cover-side water droplet guide portion 33 when the door 11 is closed. That is, the end portion of the door-side water droplet guide portion 31 is formed longer on the main body 10 side than the end portion of the door cover-side water droplet guide portion 33 when the door 11 is opened (see FIG. 5).

  As shown in FIG. 1, a case 40 is provided at the lower front portion of the main body 10. The case 40 conceals the legs (not shown) of the main body 10 and the lower part (bottom plate 10 b) of the main body 10, and has an external design effect of the main body 10. A water storage container 21 is provided at the center of the case 40. The water storage container 21 stores water used for the steam unit 20 described later to generate superheated steam. The water storage container 21 is surrounded by a guide 40b provided in the case 40, and can be inserted / removed in the front / rear direction along the guide 40b.

The water receiver 40a is below the gap between the door 11 (door cover 32) and the main body 10 and the inner box 12 when the door 11 is closed, and below the end of the door-side water droplet guide 31 when the door 11 is open. (See FIG. 5).

  The case 40 may have a drain outlet that guides water accumulated in the water receiver 40a to a drainage tank that is detachably provided at a predetermined position of the main body 10, or the case 40 may be configured to be removable.

  Next, the effect | action of the microwave oven 1 in this embodiment is demonstrated using FIG. 4 and FIG.

  FIG. 4 shows the state of condensed water when the door 11 is closed. FIG. 5 shows a state in which condensed water is guided to the water receiver 40a of the case 40 when the door 11 is open.

  When the microwave oven 1 is during steam cooking by the steam unit, the door 11 is closed as shown in FIG. At this time, the generated steam is accommodated in the heating chamber 17 until the door 11 is opened. Most of the steam adheres to the inner wall of the heating chamber 17 and the door 11 and is condensed. The condensed water W adhering to the door 11 is dropped downward along the door 11 by gravity. In particular, a large amount of condensed water W accumulates in the gap between the door 11 and the main body 10 or the inner box 12.

  When the steam cooking is finished, the door 11 is opened by the user, and the door 11 is opened as shown in FIG. The condensed water W further moves to the lower end side of the door 11 due to the impact of the door 11 being opened, and reaches the door cover side water droplet guide portion 33. The door cover side water droplet guide part 33 has a curved surface 33a from the main body 10 side to the door 11 side, and the extended line of the curved surface 33a intersects with the door side water droplet guide part 31. The transmitted condensed water W falls on the door-side water droplet guide unit 31.

  After the condensed water W falls on the door-side water droplet guide unit 31, a part of the condensed water W remains on the door-side water droplet guide unit 31, and a part of the condensed water W falls on the water receiver 40 a of the case 40 along the door-side water droplet guide unit 31. The condensed water W is finally guided to the water receiver 40a and stored in the water receiver 40a.

  Here, FIG. 6 is an enlarged view showing a microwave oven 50 as a comparative example of the microwave oven 1 shown in FIG.

  The microwave oven 50 shown in FIG. 6 is provided with a water receiver 40a at the lower part of the main body 10, but the condensed water W passing through the door 11 and the main body 10 is not guided to the water receiver 40a, and the microwave oven 50 is placed on the installation surface of the microwave oven 50. It will fall. As a result, it is necessary to clean the condensed water that has fallen on the installation surface by the user. On the other hand, the microwave oven 1 in the present embodiment can suitably guide the condensed water W due to the steam generated in the heating chamber 17 to the water receiver 40a with a simple structure.

  Moreover, the microwave oven 1 provided the door side water droplet guide part 31 which extended the front surface of the door 11 further below. The door-side water droplet guide portion 31 functions to hide the bottom plate 10b of the main body 10 at a position lower than the door 11 in front view, instead of the door 11 or the cabinet 10a.

  Here, FIG. 7 is a cross-sectional view of the microwave oven in which the lower end portion of the cabinet when the door-side water droplet guide portion 31 is not provided is indicated by a dotted line, and corresponds to FIG. When the door-side water droplet guide portion 31 is not provided, it is conceivable to extend the lower end of the cabinet 10a downward as indicated by a dotted line in order to hide the bottom plate 10b for an aesthetic effect on appearance. Since the cabinet 10a is generally an expensive coated iron plate, it is preferable that the cabinet 10a is downsized from the viewpoint of reducing the manufacturing cost of the microwave oven 1.

  On the other hand, the microwave oven 1 in this embodiment fulfill | performs the function of the cabinet 10a which the door side water droplet guide part 31 conceals the baseplate 10b as mentioned above. For this reason, the cabinet 10a can be reduced in size, and as a result, the manufacturing cost of the microwave oven 1 can be reduced.

  As shown in FIG. 5, the microwave oven 1 is provided with the door cover side water droplet guide portion 33, so that the distance between the front surface 10d of the main body 10 and the rear surface (door cover 32) of the door 11 is a distance D2. be able to. As a result, when the door cover side water droplet guide portion 33 is not provided, the distance between the front surface 10d and the door 11 is D1, and the distance between the front surface 10d and the door 11 can be reduced by (D1-D2). it can. As a result, it becomes difficult for the food waste to fall into the case 40 (water receiver 40a). Moreover, since the door cover side water droplet guide part 33 has the effect | action which hides the case 40 with respect to a user, the dew condensation water W collected on the water receiver 40a does not contact eyes.

  In addition, the door side water droplet guide part 31 of the microwave oven 1 may be configured as the microwave ovens 60 and 70 as the second and third embodiments shown in FIGS. 8 and 9. In the microwave ovens 60 and 70 in the second and third embodiments, configurations and parts corresponding to those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 8 is a diagram illustrating a microwave oven 60 according to the second embodiment.

  The microwave oven 60 includes a door-side water droplet guide 61 that functions as a water receiver when the door 11 is open. The door-side water droplet guide portion 61 has a thickness direction wall portion 62 that is further extended in the thickness direction of the door 11 in a direction orthogonal to the end portion of the door-side water droplet guide portion 31 in FIG. The thickness direction wall portion 62 is formed so that the dew condensation water W falling from the end portion of the thickness direction wall portion 62 is guided to the water receiver 40 a of the case 40 in a state where the door 11 is closed.

  The door-side water droplet guide portion 61 has a thickness direction wall portion 62, and thus functions as a water receiver that temporarily stores the condensed water W when the door 11 is opened. Moreover, the door side water droplet guide part 61 drops the condensed water W temporarily stored in the water receiver 40a when the door 11 is closed. The microwave oven 60 having such a door-side water droplet guide 61 can reliably collect the condensed water W in the water receiver 40a regardless of whether the door 11 is open or closed.

  FIG. 9 is a diagram illustrating a microwave oven 70 according to the third embodiment. In addition, illustration of case 40 is abbreviate | omitted in FIG.

  The microwave oven 70 includes a door-side water droplet guide 71 that functions as a water receiver when the door 11 is closed and opened. The door-side water droplet guide portion 71 is orthogonal to the thickness-direction wall portion 72 configured in the same manner as the thickness-direction wall portion 62 in the door-side water droplet guide portion 61 of FIG. The surface direction wall 73 is further extended toward the door 11 direction. The surface direction wall 73 is formed to have a length that is not orthogonal to the extended line of the curved surface 33 a of the door cover side water droplet guide 33. Note that the curvature and dimensions of the curved surface 33a may be set so as not to intersect with the surface-direction wall portion 73.

  When the door 11 is open, the door-side water droplet guide unit 71 functions as a water receiver that temporarily stores the dew condensation water W in the same manner as the door-side water droplet guide unit 61. At this time, even if a slight impact is applied to the door 11 or the like, the surface direction wall 73 functions as a lid for the water receiver, so that it does not flow out to the installation surface of the microwave oven 70. When the door 11 is closed, the door-side water droplet guide unit 61 functions as a water receiver having the thickness direction wall portion 62 as a bottom surface and the surface direction wall portion 73 as a side surface.

  In the microwave oven 70 having such a door-side water droplet guide portion 71, the condensed water W dripped from the door 11 is stored in the door-side water droplet guide portion 71 regardless of whether the door 11 is open or closed. . For this reason, since the case 40 does not need to serve also as a water receiver, the design freedom of the case 40 can be increased.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  For example, the door-side water droplet guide portions 31, 61, 71 and the door cover-side water droplet guide portion 33 may be provided in a part of the front left / right direction of the door 11. The water receiver 40a of the case 40 may be provided over the front left and right of the main body 10 or may be provided in part. The case 40 may be provided with a gutter for guiding the condensed water W falling from the door-side water droplet guide portion 31 to the water receiver 40a on the upper portion of the guide 40b that surrounds and guides the water storage container 21.
