Thus, as shown in FIG. 12, when tap water is discharged from the side water spout 50b1 of the water channel member 50, as shown by the solid arrow, it hits the bottom surface 9a2 of the concave portion 9a1 (see FIG. 8 ) formed in the outer cylinder cover 9a, Then, it falls onto the upper surface 8c1 of the outer peripheral portion of the balance ring 8c of the washing and dehydrating drum 8 . At this time, the washing and dehydrating drum 8 rotates at high speed, so the tap water falling on the upper surface 8c1 of the outer peripheral portion of the gimbal 8c is scattered to the inner peripheral surface 9s of the outer cylinder 9 due to the centrifugal force when the washing and dehydrating drum 8 rotates. The tap water scattered to the inner peripheral surface 9s of the outer cylinder 9 flows down in the vertical direction along the inner peripheral surface 9s of the outer cylinder 9 by the action of gravity. In addition, a plurality of side water spouts 50b1 are formed in the water channel member 50, and tap water is scattered by centrifugal force. Therefore, tap water is sprayed on the entire inner peripheral surface 9s of the upper part of the outer cylinder 9, and then flows downward. As a result, tap water flows through the entirety of the inner peripheral surface of the outer cylinder 9 from the upper part to the lower part. Thereby, dirt and dust can be removed from the entire inner peripheral surface of the outer cylinder 9, and adhesion of dirt and dust can be suppressed.

In addition, as shown in FIG. 12 , when tap water is sprayed from the bottom surface side water spout 50a1 of the water channel member 50, the tap water is sprayed onto the outer peripheral surface 8s of the upper portion (balance ring 8c) of the washing and dehydrating tub 8. The tap water sprayed on the outer peripheral surface 8s flows down vertically along the outer peripheral surface 8s of the washing and dehydrating tub 8 by gravity. In addition, a part of the tap water dripped from the side water spout 50b1 to the upper surface 8c1 of the outer peripheral portion, as shown by the thin dotted line in FIG.

By spraying tap water to the top (outer peripheral portion) of the washing and dehydrating cylinder 8 from the side water spray port 50b1 and the bottom surface side water spray port 50a1 of the water channel member 50 like this, the inner peripheral surface 9s of the outer cylinder 9 and the washing can be suppressed. Also, the dirt and dust on the outer peripheral surface 8s of the dehydration cylinder 8 are attached.

In addition, in the tub washing and spraying step S19, the washing and dehydrating tub 8 is rotated at high speed while the tap water supplied in the water supply step S16 is stored in the bottom of the outer tub 9, so that the washing and dehydrating tub 8 attached to the washing and dehydrating tub can be removed. Dirt and dust on the outer bottom surface of the cylinder 8 can also suppress the adhesion of dirt and dust.

In the drain step S20, the process control unit 112 opens the drain valve 14 to drain the rinse water in the tub 9.

In the spin-drying step S21, after the draining is completed, the process control unit 112 rotates the washing and spin-drying tub 8 at a high speed to remove moisture contained in the clothes.

Moreover, when the mode which performs a series of operation from washing to drying is set, drying process S22 is performed after dehydration process S21. In the drying process S22, the process control part 112 opens the cooling water supply solenoid valve 12c, energizes the heater 22, and drives the fan 21. After the drying process (S22) ends, the user opens the outer cover 3 and the cover part 9c to take out the clothes, closes the cover part 9c and the outer cover 3, and presses a predetermined button (such as a start button), thereby starting the following cylinder cleaning spray Step S23.

In the tub cleaning and showering step S23 , tap water is sprayed from the water passage member 50 onto the outer peripheral surface 8s of the washing and dehydrating tub 8 and the inner peripheral surface 9s of the outer tub 9 in the same manner as the tub cleaning and showering step S19 described above.

In addition, the tub washing shower steps S19 and S23 can be set ON/OFF by a switch provided in the washing and drying machine 1A.

As described above, in the washing and drying machine 1A according to the first embodiment, the outer cylinder cover 9a is provided with a water supply path (water channel member 50 ) extending in the circumferential direction of the washing and dehydrating tub 8 , and the water supply path is provided with The tap water supplied from the water supply unit 12A (water supply means) is sprayed to the side water spray port 50b1 on the upper portion (outer peripheral portion upper surface 8c1) of the washing and dehydrating tub 8. As shown in FIG. Thus, by supplying water to the water channel member 50 during the rotation of the washing and dehydrating drum 8, the tap water is scattered to the inner peripheral surface 9s of the outer cylinder 9, whereby dirt and dust adhering to the inner peripheral surface 9s of the outer cylinder 9 can be removed. , In addition, it can inhibit the adhesion of dirt and dust. This can suppress the adhesion of dirt and dust, thereby suppressing the growth of mold and the generation of odors. Furthermore, it is possible to prevent or suppress dust from adhering to the laundry during washing.

In addition, in the first embodiment, the bottom surface side water spray port 50a1 is provided to the outer peripheral surface 8s (outer peripheral surface of the balance ring 8c) of the washing and dehydrating tub 8, so that the dirt adhering to the washing and dehydrating tub 8 can be removed. Dirt and dust on the outer peripheral surface 8s, and adhesion of dirt and dust can also be suppressed. In this way, the adhesion of dirt and dust can be suppressed, thereby suppressing the growth of mold and the generation of peculiar smell, and it is also possible to prevent and suppress the adhesion of dust to laundry during washing.

In addition, the amount of water used can be suppressed by controlling the timing for executing the cartridge cleaning shower steps S19 and S23 by the process control unit 112 . That is, by performing the washing between the rinsing step and the dehydration step, clean tap water can be used for washing, so that the cartridge can be washed efficiently.

In addition, by scattering tap water by centrifugal force to clean the inner peripheral surface of outer cylinder 9 , the amount of water used can be reduced compared to cleaning by strongly splashing tap water.

The present invention is not limited to the above-mentioned embodiments. For example, as shown in FIG. The group of the through-holes 8a1 located in the upper layer and the group of the through-holes 8a1 located in the lower layer are arranged so as to overlap in the vertical direction. Thereby, the water discharged from the through-hole 8a1 located in the upper stage and the water discharged from the through-hole 8a1 located in the lower stage at the time of spin-drying are partially overlapped and discharged to the outer cylinder 9. Thereby, it is possible to prevent an area (linear area) where the water discharged during dehydration does not come into contact with on the inner peripheral surface of the outer cylinder 9 (central portion in the vertical direction of the main body plate 8 a ). In addition, although the vertical type washing-drying machine 1A, 1B was demonstrated here, it is applicable also to 1 C of drum-type washing-drying machines.

Above, as the washing machines of the first and second embodiments, the washing and dehydrating tub 8 has been described as a vertical washer-dryer in which the axis of rotation of the washing and dehydrating tub 8 is approximately vertical, and as the washing machine of the third embodiment, a rotary tub The drum-type washer-dryer 1C in which the rotation axis of the (washing and dehydrating tub) is substantially horizontal is described, but it is not limited thereto, and may be a vertical washing machine or a front-loading washing machine without a drying function.
