[Composition of the cover, base and rear frame]

The cover 41 is made of, for example, metal such as aluminum or non-magnetic stainless steel, and has a shape extending in the longitudinal direction. The upper surface 41a of the cover 41 is formed in an upwardly convex shape. The lower surface 41f of the cover 41 is also formed in an upwardly convex shape along the shape of the upper surface 41a. The lower surface of the front end 41b on the side where the conditioning container is placed in the direction orthogonal to the longitudinal direction of the lid 41 is in contact with the rear frame 30 of the top plate portion 20 via the distal end of the base 50. Therefore, it is possible to suppress the moisture ejected from the conditioning container from entering the inside of the main body casing 10 from the front end 41b. Moreover, the shape of the eaves in which the opening 41d is opened is formed on the side of the rear end 41c extending from the front end portion 41b to the rear upper side. It is preferable that the rear end 41c of the cover 41 is extended to the rear upper side than the rear edge of the opening portion 31. Even when the moisture ejected from the conditioning container passes over the upper surface 41a of the lid 41, it is possible to suppress entry into the inside of the main body casing 10 from the opening portion 31. Further, the exhaust air discharged from the opening 31 can be efficiently guided to the upper rear side without being directed upward in the opening portion 31.

A screw hole 41e screwed by a screw 51 (see Fig. 6) to be described later is formed on the lower surface 41f of the cover 41.

The susceptor 50 is made of, for example, a resin such as ABS resin, and has a frame shape extending in the longitudinal direction along the shape of the cover 41, and includes a wind direction plate portion 51 in the longitudinal direction. a plurality of spacers 52, 53, 54, and 55 for reinforcing in a direction orthogonal to the longitudinal direction are provided at a plurality of ends and between the both ends, and a through hole 52a into which the screw 51 is inserted is formed at a center of the spacer, 53a, 54a, 55a, etc. In the first embodiment, seven spacers are provided (see Fig. 3). In other words, both ends (two places) in the longitudinal direction of the cover 41, the upper part (two places) of the adjacent boundary of the three openings 31a, 31b, and 31c, and the upper part of the center part of the longitudinal direction of each opening (3 places) ). The spacers are provided at both ends of the cover 41 in the longitudinal direction, the three openings 31a, Since the upper portions of the adjacent boundaries of 31b and 31c are arranged, the pressure loss to the exhaust air from the opening portion 31 can be suppressed.

Further, the front portions of the respective spacers are provided with receiving portions 52b, 53b, 54b, 55b and the like that abut against the lower surface 41f of the cover 41. Since the bearing is disposed at the front of each of the spacers, for example, even if a part of the conditioning container is placed on the upper surface of the cover 41, since the weight of the conditioning container is received by the plurality of receiving portions, the strength of the base 50 becomes high. . Further, in the rear portion of each of the spacers, the wind direction plate fixing portions 52c, 53c, 54c, 55c and the like for fixing the wind direction plate portion 51 are provided, and the wind direction plate fixing portion rectifies the direction of the exhaust air from the opening portion 31 into the opening portion. Since the exhaust air which is discharged from the opening 31 is prevented from being enlarged and discharged in the longitudinal direction of the opening 31 from the opening 41d of the cover 41.

In a state where the cover 41 is attached to the base 50, the cover 41 can be attached to the rear frame 30 via the base 50 by inserting the screw 51 from the lower side of the rear frame 30.

The ejected moisture cannot enter the body casing from the front end portion of the cover. Further, if the water does not extend beyond the front end portion of the lid to the upper lid of the eaves shape, the opening portion cannot be reached, and the main body casing can be prevented from entering the opening portion. Further, the cross-sectional area of the opening through which the cooling air is discharged is easily ensured, and the required body cooling performance can be ensured. Further, since the cooling air discharged from the opening is guided to the lower surface of the cover and rearward and upward, the cooling air that hits the wall is diffused as compared with the case of the rear side, and the occurrence of condensation on the wall is suppressed. .

Moreover, since the upper surface of the cover is formed in a convex shape, it is possible to obtain the harmony of the shape of the top plate and the cover of the flat surface without impairing the appearance of the cover.

Further, since the cover is made of metal and has heat resistance, a part of the high-temperature conditioning container is accidentally placed on the upper surface of the cover, and the cover can be prevented from being thermally deformed. Further, it is possible to obtain the harmony of the color tone of the flat top plate and the cover without impairing the appearance of the cover.

Moreover, since the cover is supported from below by the base, the mounting strength of the cover can be increased.

Further, since the susceptor includes the wind direction plate portion, the discharge direction of the cooling air can be appropriately set, and the occurrence of condensation on the wall can be suppressed.

Moreover, since the susceptor is made of resin, it has the advantage that the susceptor is easy to manufacture.

Further, in the heating conditioner according to the first embodiment, the cover is provided to cover the opening for discharging the cooling air for cooling the components in the main body casing, but the cooling air for cooling the components in the main body casing may be sucked.
