  FIG. 2 is a side view drawn so that the internal structure of the washing machine in the embodiment of the present invention can be understood. In the following description, a drum type washing / drying machine provided with a heat pump type dehumidifying / drying means will be described as an example.

  As shown in FIG. 2, a rotating drum 1 in which a large number of through holes are formed and which is rotated and accommodates laundry is provided in a water tank 2.

The control circuit 100 controls the water supply and drainage into the water tank 2 and the rotation of the rotating drum 1 to perform washing, rinsing, and dehydration steps (hereinafter, these three steps are collectively referred to as “washing operation”). To implement.

  Further, the control circuit 100 drives the blower fan 4 which is a blower, and the laundry is dried by circulating the air in the water tank 2 through the circulation blower passages 9 and 11 including the dehumidifier and the heater. It is supposed to be.

  Here, as an example, the dehumidifying means and the heating means are constituted by an evaporator 19 and a condenser 17 that constitute an air conditioner connected to the compressor 16 by a refrigerant circuit, and the air in the water tank 2 is circulated and blown by the blower fan 4. By introducing air from the circulating air introduction pipe 5 introduced into the paths 9 and 11, water vapor is condensed in the evaporator 19, and heating is performed again in the condenser 17. The inside is repeatedly blown and exposed to the laundry in the rotating drum 1 to be efficiently dried. Hereinafter, the configuration will be described in more detail.

  As shown in FIG. 2, the drum-type washing / drying machine includes a rotating drum 1 in which a water tank 2 is suspended in a washing machine body 210 by a suspension structure (not shown) and is formed in a bottomed cylindrical shape in the water tank 2. However, the axial center direction is inclined downward from the front side toward the back side.

  On the front side of the aquarium 2, a clothing doorway leading to the opening end of the rotary drum 1 is formed, and a door 35 that closes an opening provided on an upward inclined surface formed on the front side of the washing machine body 210 so as to be openable and closable. By opening, the laundry can be taken in and out of the rotary drum 1 through the clothing doorway.

  Since the door 35 is provided on the upward inclined surface, it is possible to carry out the work of putting in and out the laundry without bending down, and in general, compared with a drum-type washing and drying machine in which the laundry is taken in and out from the horizontal opening. Workability has been improved.

  The rotating drum 1 has a large number of through-holes communicating with the water tank 2 on its peripheral surface, and agitation protrusions (not shown) are formed at a plurality of positions on the inner peripheral surface. The rotary drum 1 is rotationally driven in the forward and reverse directions by a motor 3 attached to the back side of the water tank 2. In addition, a water injection pipe and a drain pipe 40 (not shown) are piped to the water tank 2, and water injection and drainage into the water tank 2 are performed by control of a water injection valve and a drain valve 27 (not shown).

  The door 35 is opened, laundry and detergent are put into the rotating drum 1, the operation panel provided at the upper front of the washing machine body 210 is operated, and the control circuit 100 provided inside the washing machine body 210. Operation is started through control by.

  A predetermined amount of water is injected into the water tank 2 from the water injection pipe, and the rotary drum 1 is driven to rotate by the motor 3 to start the washing process. By the rotation of the rotating drum 1, the laundry accommodated in the rotating drum 1 is lifted in the rotating direction by the stirring protrusion provided on the inner peripheral wall of the rotating drum 1, and agitated to fall from the lifted appropriate height position. Since the operation is repeated, the laundry has the effect of tapping and washing.

  After a predetermined washing time, the dirty washing liquid is discharged from the drain pipe 40, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation of rotating the rotary drum 1 at a high speed. Rinsing is performed by pouring water from the road. Also in this rinsing process, the laundry stored in the rotating drum 1 is rinsed by repeating the stirring operation in which the laundry is lifted and dropped by the stirring protrusion by the rotation of the rotating drum 1.

  This drum-type washing / drying machine has a function of drying laundry stored in the rotary drum 1 and dehumidifies the air in the water tank 2 as shown in FIG. The circulation air flow paths 9 and 11 described above for heating and blowing the dried air into the water tank 2 again are formed.

  In the middle of the circulation air flow paths 9 and 11, a dehumidifying means such as an evaporator 19, a heating means such as a condenser 17, and a blower fan 4 that is a blower means are arranged.

  By rotationally driving the blower fan 4, an air flow is generated in the circulation blower paths 9 and 11, and the air in the rotary drum 1 containing the laundry flows from the water tank 2 to the blower fan 4 side through the through holes. The circulated air introduction pipe 5 is exhausted.

  The air exhausted to the circulating air introduction pipe 5 is dehumidified by dewing moisture in the evaporator 19 located upstream of the blower fan 4 and is also heated by heat exchange with the condenser 17 and is always dried. High temperature air.

  The dried high-temperature air is sent from the blower fan 4 to the circulation airflow paths 9 and 11 from the water tank 2 to be blown into the water tank 2. The high-temperature dry air blown into the water tank 2 enters the rotary drum 1 through the through holes, escapes to the water tank 2 while being exposed to laundry such as clothes, and is again introduced to the circulating air introduction conduit 5. The Thus, a drying process is implemented by the repetition of the circulation of the air in the circulation ventilation paths 9 and 11.

  Further, in the drying process using such a circulation air passage, foreign matter such as lint mainly generated from laundry such as clothes is circulated in the circulated air, and the eyes of the evaporator 19 and the condenser 17 are circulated. It is difficult to perform a drying process such as clogging, biting into the rotating part of the blower fan 4, and deposition on the inner surface of the blower fan 4, and maintenance is required.

  In order to remove such foreign matter, a filter for removing foreign matter in the circulating air is arranged in the middle of the circulating air passage (specifically, upstream of the evaporator 19, the condenser 17, and the blower fan 4). As a result, even if foreign matter enters the air after the laundry is dried, it is collected by the filter when passing through the filter and does not enter the circulating air downstream. . Therefore, the functions of the evaporator 19, the condenser 17, and the blower fan 4 are maintained for a long time.
