By opening the lid 26, washing is performed in the rotating drum 20 via the aquarium clothing entrance 27 and the rotating drum clothing entrance 28. The laundry is put in and the laundry can be taken out from the rotary drum 20. Since the lid body 26 is provided on the upward inclined surface 25a, the user can reduce the degree of bending his / her waist when putting in and out the laundry.

  As shown in FIG. 2, the suspensions 29 a and 29 b are constructed by suspending the suspension from the water tank 22 and suspended from the housing 25. The water tank 22 is supported by dampers 30a and 30b fixed to the lower end of the housing 25. With the above configuration, the water tank 22 is supported in an anti-vibration manner, and vibrations accompanying the rotation of the water tank 22 are prevented from being transmitted to the housing 25.

  The drying function includes an exhaust port 34, a dehumidifying means accommodating chamber 35, a heat exchanger 37, a water injection valve 39, a water injection nozzle 38, a lint collecting filter 40, a blower duct 41, a blower fan (blower means) 33, and a heating duct 42. The heater (heating means) 43, the hot air blowing path 36, and the blowing port 44 form a circulation path. The configuration and operation will be described below.

  Due to the rotation of the blower fan 33, the air in the rotary drum 20 exits from the through hole 21 formed in the peripheral surface into the water tank 22 and enters the dehumidifying means accommodation chamber 35 from the exhaust port 34 provided in the upper part of the trunk of the water tank 22. Inflow. A heat exchanger 37 and a water injection nozzle 38 serving as a dehumidifying means are disposed in the dehumidifying means accommodation chamber 35, and water injected by opening the water injection valve 39 is sprinkled from the water injection nozzle 38 onto the heat exchanger 37. Therefore, the air containing moisture exhausted into the dehumidifying means accommodation chamber 35 is cooled and dehumidified. The air dehumidified in the dehumidifying means accommodating chamber 35 passes through the lint collecting filter 40 provided in the air duct 41 and is guided to the rear of the water tank 22, and the heating pipe 42 provided on the back surface of the water tank 22. , Heated by the heater 43, sent to the hot air blowing path 36 provided at the rear of the water tank 22, and blown into the water tank 22 from the air outlet 44 provided at the upper back of the water tank 22. Since the air blown into the water tank 22 flows into the rotary drum 20 from the air holes 21 formed on the bottom surface of the rotary drum 20, moisture is taken away from the laundry by the dehumidified and heated air, and the rotation of the rotary drum 20 is performed. The drying of all the laundry is promoted by the agitation, and the laundry is dried by repeating this air circulation for a predetermined time.

  As shown in FIG. 3, the dehumidifying means accommodation chamber 35 is integrated with a water tank 22 formed into a substantially cylindrical shape by resin molding, and is located on the upper right side (position of about 45 degrees) when viewed from the front of the water tank 22. An exhaust port 34 that is formed at the same time and is opened toward the dehumidifying means accommodation chamber 35 by opening a part of the side peripheral wall of the water tank 22 is formed. The exhaust port 34 opens in a substantially tangential direction of the rotation direction of the rotary drum 20.

  Further, a left rib 55 having a through hole 55a is provided on the side peripheral surface of the upper left portion (position of about 45 degrees) when viewed from the front of the water tank 22, and the water tank 22, the rotating drum 20, the motor 23, a drying function, and the like are united. The integrated water tank unit is integrally provided at a substantially center of gravity in the front-rear direction. On the other hand, on the outer peripheral surface of the dehumidifying means accommodating chamber 35 formed simultaneously on the side peripheral surface of the upper right portion when viewed from the front of the water tank 22, a stepped portion 35a is formed in one step, A right rib 56 having a through hole 56a is integrally provided at a substantially center of gravity position in the front-rear direction of the water tank unit in which the water tank 22, the rotating drum 20, the motor 23, the drying function and the like are unitized.

Further, the suspension 29 b is formed in a hook shape at both ends, one end is hooked on the upper right side of the housing 25, and the other end is hooked on the through hole 56 a of the right rib 56. Here, the suspension 29b is set shorter than the suspension 29a, and the suspension 29a and the suspension 29b are individually set with a spring constant so that the water tank unit can be balanced on the left and right.

  The operation of the above configuration will be described.

  The lid 26 is opened, the laundry is put into the rotating drum 20, a required amount of detergent is put into the detergent inlet provided in the water supply unit 31, and the operation is performed from the operation panel provided on the surface of the housing 25. When a start operation is performed, a predetermined amount of water corresponding to the laundry is supplied from the water supply unit 31 into the water tub 22, and the rotating drum 20 is rotationally driven by the motor 23, whereby the washing process is performed. When the washing process is completed, the dirty washing water is discharged from the drainage unit 32, the rotating drum 20 is rotated at a high speed, the washing water is dehydrated, and water is newly supplied from the water supply unit 31 into the water tank 22. Then, the rinsing process is performed. When the rinsing process is completed, a dehydrating process is performed in which the rotating drum 20 is rotated at a high speed to dehydrate the rinse water contained in the laundry. When the operation course for performing the drying process subsequent to the dehydration process is selected, the air in the water tank 22 is exhausted to dehumidify it from the air containing moisture, and heated and dried again as hot air in the water tank 22. A drying step of blowing air is performed.

  As shown in FIG. 1, when the drying process is performed, the laundry progresses and yarn waste is easily generated from the laundry, and flows into the dehumidifying means accommodation chamber 35 from the exhaust port 34 by air blowing (arrow A). ). The lint and the like existing in the air are configured so that only the air is filtered by the lint collecting filter 40 provided at the inlet of the blower duct 41 and the lint and the like do not flow into the blower duct 41 and the heating duct 42. However, there are many cases where it adheres to the inner wall of the heat exchanger 37 or the dehumidifying means accommodation chamber 35 before that. If the attachment of yarn waste or the like increases, the dehumidifying function or the air blowing function is lowered, so it is necessary to remove the yarn waste or the like attached in the dehumidifying means accommodation chamber 35.

  In the present embodiment, as will be described with reference to FIG. 3, in order to remove lint and the like adhering in the dehumidifying means accommodating chamber 35, the rotation of the rotary drum 20 at a predetermined number of revolutions during the rinsing process is performed. The water splashed in the direction (arrow B) can be vigorously flowed into the dehumidifying means accommodation chamber 35 from the exhaust port 34 (arrow C), and the lint etc. adhering to the heat exchanger 37 and the pipe wall can be washed away. . Note that the predetermined rotation speed of the rotating drum 20 in this case may be any rotation speed at which water jumps up and rotates along the inner wall of the water tank 22 due to the centrifugal force of rotation of the rotating drum 20 (for example, rotation When the diameter of the drum 20 is about 500 ± 50 mm, about 150 r / min).

  As described above, since the exhaust port 34 is opened in a substantially tangential direction of the rotation direction of the rotary drum 20, water stored below the water tank 22 in the rinsing step is splashed by the rotary drum 20. Then, it scatters in the tangential direction of the rotating direction of the rotating drum 20 and flows into the dehumidifying means accommodating chamber 35 from the exhaust port 34 with a great force. By repeating this during the rinsing step, the attached lint etc. are washed away. In the dehumidifying means storage chamber 35, a drainage path is formed in which water generated by dehumidification or water injected from the water injection nozzle 38 flows into the water tank 22 and is discharged from the drainage part 32 to the outside. Washed out lint and the like are also discharged to the outside along with the waste water.

  With the above effect, the reliability as a washing and drying machine is improved, and in the present embodiment, the dehumidifying means accommodation chamber 35 is formed integrally with the water tub 22, and the suspension 29 b is formed on the side peripheral wall of the dehumidifying means accommodation chamber 35. By adopting a configuration for mounting, it is possible to reduce the number of components and make it compact.

  In the first embodiment, the dehumidifying means accommodating chamber 35 is provided on the side peripheral surface of the upper right portion when viewed from the front of the water tank 22, but the dehumidifying means accommodating chamber 35 is opposite from the front of the water tank 22. Even if it is provided on the side peripheral surface of the upper left portion as viewed and other configurations are formed in reverse, the same effect can be obtained.

  Further, in the first embodiment, the configuration in which the rotary drum 20 is arranged in an inclined manner is shown, but the same configuration can be made when the rotary drum 20 is arranged in the horizontal direction.

  As described above, the drum type washing and drying machine according to the present invention has a configuration in which the dehumidifying means accommodation chamber is provided adjacent to the upper portion of the side peripheral surface of the water tank and the suspension is attached to the side peripheral wall of the dehumidifying means accommodation chamber. Since other parts such as a water tank elastically supported by the housing can be made compact, it is useful as an industrial device having a drying function.
