The motor 9 has two drive shafts (a first drive shaft 9a and a second drive shaft 9b). The rotational force of the first drive shaft 9a is transmitted to the rotating drum 1 via the first transmission belt 9c, causing the rotating drum 1 to rotate. Rotation of the rotary drum 1 is performed in order to constantly move the clothes W contained therein without stopping at a fixed position. The rotational force of the second drive shaft 9b is transmitted to the fan rotating shaft 8c of the dehumidification fan 8a via the second transmission belt 9d, thereby rotating the dehumidification fan 8a. An air current is formed inside the rotary drum 1 by the rotation of the dehumidifying fan 8a.

The combustion unit 10 comprises a gas burner 10a, a gas injection nozzle 10b, and a gas supply valve device 10c. The fuel gas supplied from the gas supply valve device 10c is injected from the gas injection nozzle 10b toward the gas inlet 10d of the gas burner 10a. As a result, the fuel gas is led to the gas burner 10a together with the air around the gas inlet 10d and burned to heat the outside air. Combustion air supplied to the gas burner 10a is also taken in from the air supply port 2c at the bottom of the housing 2, as is the air for heating.

The hot air duct 11 extends from above the gas burner 10 a to a hot air outlet 5 a formed in the ring plate 5 . The hot air heated and generated by the gas burner 10 a is led to the hot air outlet 5 a through the hot air duct 11 and sent into the rotating drum 1 .

The warm air sent into the rotary drum 1 dries the clothes W stored in the rotary drum 1, passes through the filter unit 6, and goes to the moisture exhaust fan 8a. At this time, lint generated from the clothes W is captured by the filter unit 6 .

The high-humidity hot air that has passed through the filter unit 6 and is directed to the moisture exhaust fan 8a enters from the front side of the moisture exhaust fan 8a, goes to the outer periphery of the moisture exhaust fan 8a, is concentrated in the exhaust path 7, and is discharged from the exhaust port 7a to the outside of the machine. discharged to

It will be in a standing state so as to protrude toward you.

On the other hand, as shown in FIGS. 4 and 6, the front plate 22 has an extension portion 22a extending rearward (toward the rear lid 23) from the upper edge thereof. The height of the upper surface of the extended portion 22 a corresponds to the height of the upper surface of the top plate 20 when the top plate 20 is attached to the housing component 27 . Therefore, the upper surface of the extended portion 22a forms the upper surface of the housing 2 together with the upper surface of the top plate 20 (see FIG. 2). A plate-shaped first locked portion 22b extends downward from the lower surface of the extended portion 22a.

In the case component 27, the front plate 22 is attached to the case component 27 by hooking the first locked portion 22b to the main body portion 26c of the reinforcing member 26 from above. That is, the front plate 22 is fixed to the housing component 27 via the reinforcing member 26 .

As a result, the front plate 22 and the housing component 27 can be fixed to the housing component 27 (and thus the housing 2) without screwing the front plate 22 from the front side. It's becoming As a result, the housing 2 not only prevents deterioration of workability during assembly, but also improves the appearance of the front side.

In the case 2, after the front plate 22 is attached to the case component 27 as described above, the main body portion 26c of the reinforcing member 26 and the first edge portion 24a and the second edge portion 24b of the side plate 24 are The front plate 22 is fixed to the housing component 27 by screwing from the rear.

This is for the purpose of making it possible to easily attach and detach the front plate 22 to and from the housing component 27, and to improve the appearance by making the screw fastening invisible on the front side.

However, the housing for a clothes dryer of the present invention is not limited to such a configuration, and the front plate may be detachably attached to the housing component without intervening the reinforcing member. For example, when a hole for screwing and a part for closing the hole are used, the reinforcing member may be omitted and the front plate may be attached to the housing part only by screwing.

In addition, in the housing 2 , the reinforcing member 26 maintains the space between the pair of left and right side plates 24 together with the bottom plate 21 . Therefore, in the case 2 , even if the front plate 22 is removed and only the case component 27 is used, the pair of side plates 24 can be kept upright with respect to the bottom plate 21 .

Therefore, when the reinforcing member is omitted, it is preferable to separately provide means for maintaining the space between the left and right side plates so that the left and right side plates stand upright with respect to the bottom plate. For example, the left and right side plates and the front plate may be configured as one component, and the bottom plate may be detachably attached to the component.

Further, in the housing 2 of the present embodiment, the reinforcing member 26 is used to make the front plate 22 and the top plate 20 easily detachable. Therefore, the first end portion 26a, which is one end portion of the reinforcing member 26, is fixed to the upper end of the first edge portion 24a of the pair of left and right side plates 24 on the front plate 22 side. The second end portion 26b, which is the other end portion, is fixed to the upper end of the second edge portion 24b of the pair of side plates 24 on the other front plate 22 side.

However, the housing for a clothes dryer of the present invention is not limited to such a configuration, and the reinforcing member may be bridged between the left and right side plates. Specifically, each of the left and right ends of the reinforcing member may be fixed to the left and right side plates. For example, in the case of a structure in which the front plate and the top plate are not locked to the reinforcing member, the front plate may be positioned below the upper edges of the left and right side plates and at the central portion in the front-rear direction.
