にも優れたものとなって商品性を高めることができる。According to this embodiment having the structure described in -I-, the door 17 is composed of the door frame 18 and the inner plate 19, and since both can be integrally molded, it is sufficient to treat them as one component in terms of parts management. , and also eliminates the need to assemble the 17i117. Therefore, compared to the conventional configuration in which these parts had to be molded separately and then assembled one by one using screws or the like, this is extremely advantageous in terms of parts management and assembly work, and manufacturability is greatly improved. Furthermore, since the door frame 18 and the inner plate 19 are integrated at the joint 20 with their resins fused to each other, unlike a structure in which they are joined by screws, engagement claws, etc., there is no gap between them. It has no generation, has excellent airtightness, and has an excellent appearance, which can improve marketability.

ることができる。Furthermore, in view of the fact that the door frame 18 and the inner plate 19 are integrally molded, the outer periphery of the joint 20 between the two is positioned outside the annular shielding wall 21 that is airtightly separated from the opening 3. This prevents the hot air inside the drum 5 from hitting at least the outer peripheral portion of the joint 20. As a result, even though the joint 20 of the door 17 is more susceptible to adverse thermal effects than other parts, the entire joint 20 is exposed to hot air and its hardening strength is reduced. This can prevent this from happening, thereby increasing the fixing strength of the inner plate 19 to a level comparable to that of screwing, and also preventing deformation due to thermal effects. Furthermore, especially in this embodiment, since the pivot shaft 23 of the door 17 is formed into a cylindrical shape with slotted grooves instead of the conventional solid shaft, the following incidental effects of feature a of this embodiment are also obtained. Obtainable. That is,
For example, if a strong impact force is applied to the pivot part of the door 17, such as by forcefully opening the door 17 with excessive force, the outer box There was a problem that the front plate would break at the force-receiving hole portion. When such damage occurs, it is necessary to replace the front plate in order to repair it, but since the front plate is large and expensive, and has a structure that supports the front side of the drum, it is difficult to replace it. It requires a lot of effort. On the other hand, in this embodiment, door 1
Since the structure is such that the strength of the axis 23 of D+f 17 is reduced relative to tlJ, if an impact force that would damage the front plate 2 is applied, the axis 23 of D+f 17 will be damaged first before the front plate 2 is damaged. It will break. Therefore, in such a case, it is sufficient to replace the door 17, which is small, cheap, and easy to replace, and overall repair costs and labor can be sufficiently reduced.

Even if it is designed to break, the same effect as described in -L can be achieved.

An annular shielding wall portion 31 is integrally protruded from an annular region surrounding the door frame 28, and has a surrounding wall portion 29a suspended from the surrounding wall portion 28b of the door frame 28 on the outer periphery. As shown in FIG. 8, on the surface of the inner plate 29 facing the drum 5, a large number of reinforcing ribs 32 are integrally molded radially between the annular shielding wall 31 and the surrounding wall 29a. The portion where the reinforcing ribs 32 are formed is covered by the joint portion 30 from the front side. Further, when the door is closed, the tip of the annular shielding wall 31 comes into contact with the front end surface of the gasket 22, and the back side of the door is thus airtightly divided with the annular shielding wall 31 as a boundary.
This is similar to the example.

ことができる。Furthermore, since the reinforcing ribs 32 are integrally molded on the inner plate 29,
The strength of the inner plate 29 and the entire door can be sufficiently increased, and deformation caused by the opening and closing operations of the door can be suppressed accordingly, making it possible to improve the operability of opening and closing the door, and also to achieve cost advantages. Since resin such as polypropylene can be used, manufacturing costs can also be reduced. Furthermore, since the t+li strong ribs 32 are provided in the forming area of the joint portion 30, even if so-called flesh marks occur on the inner plate 29 due to the reinforcing ribs 32, this will be avoided during molding of the door frame 28. Since it is hidden, it does not reach the surface of the door, and it is possible to reliably prevent the appearance from being damaged.

することができるものである。The present invention is not limited to the embodiments described above and shown in the drawings; for example, the door frame and the inner panel may be made of the same resin but different in color (different materials). Alternatively, as a combination other than the resins already exemplified, for example, the door frame 18 may be made of high-strength resin and the inner plate 19, which does not require relatively strength, may be made of inexpensive resin. The present invention can be modified and implemented in various ways without departing from the gist, such as application to equipment that uses warm air and hot water.
