The washing and dehydrating tub 8 has a bottomed cylindrical shape and has a main body plate 8a formed of a stainless steel plate or the like. A plurality of through holes 8a1 (only a part of which is shown) for water and air passage are formed in the main body plate 8a. The washing and dehydrating tub 8 has a rotary impeller 8b at the inner bottom surface.
The outer tub 9 has a cylindrical shape with a bottom, and coaxially encloses the washing and dehydrating tub 8, and an outer tub cover 9a is provided at an upper portion thereof. The user of the washing and drying machine 1 can open the outer lid 4 and the lid member 9b of the outer tub cover 9a to move the laundry into and out of the washing and dehydrating tub 8 through the opening 5.
The driving device 10 is disposed at the outer center of the bottom surface of the tub 9. The driving device 10 has a motor 10a and a coupling mechanism 10b, and is configured such that a rotation shaft 10c of the driving device 10 penetrates the outer tub 9 and is coupled to the washing and dehydrating tub 8 and the rotary impeller 8b. The coupling mechanism 10b has a function of transmitting the rotational power of the motor 10a to at least one of the washing/dehydrating tub 8 and the rotary impeller 8b.
The water supply unit 7 is provided on the depth side of the upper surface cover 3. The water supply unit 7 supplies tap water from the water supply hose connection port 6 to the input device 11 and the water-cooling dehumidification means (not shown). The water supply unit 7 can supply tap water or bath water from the water supply hose connection port 6 into the outer tub 9 through the water supply hose 13 from between the outer tub 9 and the washing and dehydrating tub 8. The water supply unit 7 can supply tap water from the water supply hose connection port 6 to the upper part of the washing and dehydrating tub 8 through the cleaning hose 14.
The falling portion 15 provided on the bottom surface of the outer tub 9 communicates with the lower communication pipe 16. The lower communication pipe 16 is connected to the wash water discharge passage 18 via the drain valve 17.
A drain hose, not shown, for sending drain water to the outside of the machine is connected to the washing water discharge path 18.
In addition, by closing the drain valve 17, the washing water and the rinsing water can be stored in the outer tub 9. Further, by opening the drain valve 17, the water (wash water, rinse water) in the outer tub 9 can be discharged to the outside of the washing and drying machine 1 through the wash water drain passage 18.
A drying duct 12 as an air blowing passage is integrally provided with the back surface of the tub 9. A water-cooling dehumidifying mechanism (not shown) is incorporated in the drying air duct 12, and the water supply unit 7 supplies cooling water (tap water) to the water-cooling dehumidifying mechanism. The cooling water flows along the wall surface (metal plate made of stainless steel or the like) of the drying air duct 12, flows into the drop portion 15, and is discharged to the outside of the machine through the lower communication pipe 16 and the washing water drain passage 18.
An outlet of the drying air duct 12 is connected to an inlet of a fan 20 as an air blowing unit, and an outlet of the fan 20 is connected to a heater 21. The outlet of the heater 21 is connected to a blow nozzle 24 via a blowing air duct 22 and a corrugated tube 23 made of rubber. That is, the fan 20 serving as the blowing unit blows the air blown from the blowing nozzle 24 to the laundry put into the inner tub.
That is, when the fan 20 is driven, the air in the outer tub 9 flows into the drying duct 12. The air water-cooled and dehumidified by the drying duct 12 is discharged from the fan 20, heated by the heater 21, and blown out into the washing and dehydrating tub 8 from the blow-out nozzle 24 as high-temperature and low-humidity air.
Although not shown, a temperature sensor for detecting the temperature of the washing water and the temperature of the air discharged from the washing water discharge path 18 to the outside of the machine during the drying operation is provided between the lower communication pipe 16 and the water discharge valve 17.
The washing and dehydrating tub 8 has a balance ring (also referred to as a fluid balancer) 8c formed of synthetic resin or the like at an upper end edge portion of the main body plate 8a. The balance ring 8c is formed by injecting a fluid having a large specific gravity into the interior thereof, and has a function of maintaining the balance of rotation by removing eccentricity by the movement of the fluid in the balance ring 8c when the eccentricity is generated due to the offset of the laundry or the like at the time of rotation of the washing and dehydrating tub 8.
The outer tub cover 9a has a substantially semicircular inlet and is attached to an upper end edge of the outer tub 9. A cover member 9b is provided at the inlet port to be attached so as to be openable and closable. Although not shown, a connection port to which the bellows 23 is connected and a connection port to which a cleaning hose 14 for cleaning a tub, which will be described later, is connected are provided on the depth side (rear side) of the outer tub cover 9 a.
In the outer tub cover 9a, a water spreader 25 is fixed to a lower surface of the outer tub cover 9a via a plurality of screws. The water sprinkling device 25 is formed in a substantially annular shape and is disposed so as to rotate along the peripheral edge of the outer tub cover 9 a.
The washing and drying machine 1 further includes a dust collecting device 26 near a connection portion between the drying air duct 12 and the suction bellows 28, and the dust collecting device 26 collects a part of the cleaning water flowing through the drying air duct 12 as an air blowing passage and causes the collected dust to flow into the air blowing passage to clean the collected dust. The dust collecting device 26 in the present embodiment is formed of resin, and is not limited thereto as long as predetermined mechanical strength and workability can be obtained, and it may be formed of other materials such as metal.
Fig. 2 shows the arrangement of the outer tub 9, the dust collecting device 26, the duct cover 27, and the suction bellows 28. The dust collecting device 26 is attached so as to be sandwiched between the outer tub 9 and the duct cover 27. The dust collecting device 26 is provided in a partial region (a region of a part of the connection portion) where the fan 20 serving as the air blowing portion and the drying air duct 12 serving as the air blowing passage are connected.
Fig. 3 is a perspective view of the dust collection device 26. The dust collecting device 26 includes: a slope part 26a as a water collecting part for collecting a part of the washing water, and a hole 26b for injecting the collected part of the washing water into a nozzle 26c as a dust collecting part where dust is accumulated. The nozzle 26c has a plurality of nozzles, each of which has a structure in which the cross-sectional area decreases as it goes downward, and has a comb-tooth shape.
As a result, the air circulating in the dry air duct 12 flows upward from below in the drawing, and at this time, the dust contained in the air is retained in the portion of the nozzle 12c (dust retention portion S in fig. 4) serving as the dust collection portion. Further, by providing the nozzle 12c to collect the dust, a part of the washing water flowing toward the slope portion 26a as the water collecting portion is circulated to the nozzle 12c through the hole 26b, whereby the dust retention portion S can be sufficiently washed.
Fig. 4 is a front sectional view of the outer tub 9, the dust collecting device 26, the duct cover 27, and the suction bellows 28 in an attached state. W denotes cleaning water, and S denotes a dust retention portion. The washing water W flowing through the back side of the suction bellows 28 falls to the slope portion 26a of the dust collecting device 26 and is conveyed to the upper side of the dust retention portion S. Then, the cleaning water W is injected into the dust retention section S through the hole 26b formed in the dust collection device 26. This enables the dust retention portion S to be sufficiently cleaned. The cleaning water W is water for cleaning the air blowing passage, and is not cooling water used in the drying operation.
