Next, the operation of the washing/drying machine S according to the present embodiment during the drying operation will be described.
As shown in FIG. 1, during the drying operation, the washer/dryer S rotates the rotor disk 4 forward and backward while rotating the fan 61 (see FIG. 5) in the drying unit 60 at high speed. As a result, the air in the outer tank 2 is sucked out into the bottom circulation path 20, and when it passes through the vertical dehumidifying path 21, the cooling water flowing down from the cold water dehumidifying section 22 installed in the vertical dehumidifying path 21 is cooled. Cools and dehumidifies by touch. The cooled and dehumidified drying air is passed through the filter 51 to collect foreign matter such as lint, heated by the heater 63 (see FIG. 2), and then blown into the washing and dehydrating tub 3 from the outlet 23a. . Then, when the drying of the laundry is detected using a temperature sensor (not shown), the drying operation ends.

As described above, the washing and drying machine S according to this embodiment includes the housing 1, the washing and dehydrating tub 3, the drying unit 60, the filter storage case 52, the tray 71, and the first elastic member 80. It has The drying unit 60 has a blower motor 62 that rotates a fan 61 that blows drying air into the washing/dehydrating tub 3 . The filter housing case 52 is arranged below the drying unit 60 and detachably houses the filter 51 . The tray 71 is attached to the housing 1 and supports the drying unit 60 and the filter housing case 52 . The first elastic member 80 is made of rubber and interposed between the drying unit 60 and the filter housing case 52 . By screwing the drying unit 60 to the tray 71 , the drying unit 60 is pressed against the filter storage case 52 via the first elastic member 80 .

In this embodiment, by screwing the drying unit 60 to the tray 71, the first elastic member 80 is compressed between the drying unit 60 and the filter storage case 52 and pressed against both of them. Let me. Therefore, the drying air that has passed through the filter storage case 52 can be reliably sent to the drying unit 60 while suppressing leakage by the first elastic member 80 . For this reason, the drying unit 60 can be configured so as not to be screwed to the filter housing case 52 . The vibration of the blower motor 62 is absorbed by the first elastic member 80 and is suppressed from being transmitted to the filter housing case 52 . As a result, even if the blower motor 62 of the drying unit 60 is rotated at high speed, the vibration of the blower motor 62 is less likely to be transmitted to surrounding members such as the filter storage case 52, thereby reducing noise. On the other hand, by rotating the blower motor 62 at a high speed, it is possible to apply a large amount of drying air to the clothes. As a result, wrinkles in the clothes can be reduced, and the dried finish state is improved.
Therefore, according to the present embodiment, it is possible to provide the washer/dryer S capable of reducing the noise during the drying operation while improving the dried finished state of the clothes.

Further, in this embodiment, the drying unit 60 is screwed to the tray 71 via the second elastic member 85 made of rubber. In this configuration, the second elastic member 85 suppresses the vibration of the blower motor 62 from being transmitted to the tray 71 . This further reduces noise during the drying operation.

Further, in the present embodiment, the number of attachment portions 72 closer to the exit 69 than the entrance 68 in the unit case 64 is greater than the number of attachment portions 72 closer to the entrance 68 than the exit 69 . Here, the wind pressure in the unit case 64 is greater near the outlet 69 through which the drying air flows than near the inlet 68 . However, by increasing the number of mounting portions 72 screwed to the tray 71 near the outlet 69 than near the inlet 68, it is possible to suppress leakage from the vicinity of the outlet 69 even with high-speed wind and a large amount of drying air. be able to.

Further, in this embodiment, the unit case 64 has a duct portion 67 forming a curved flow path on the downstream side in the drying air flow direction, and the outlet 69 is formed at the tip of the duct portion 67. there is In this configuration, the wind pressure increases in the curved flow path of the duct portion 67, but since the number of mounting portions 72 increases near the outlet 69, it is possible to suppress the drying air from leaking from the vicinity of the outlet 69. .

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the described configurations. Moreover, it is possible to add, delete, or replace a part of the configuration of the embodiment described above with another configuration.

For example, in the above-described embodiment, the first elastic member 80 is configured to include the inner peripheral portion 81 and the outer peripheral portion 82, but is not limited to such a shape. The first elastic member 80 may have, for example, a ring plate shape with a rectangular cross section or an O-ring shape with a circular cross section. Alternatively, the first elastic member 80 may be configured to include only the inner peripheral portion 81, for example.
