Description

  The present invention relates to a laundry dryer and a dryer provided with means for drying laundry such as clothes.

FIG. 8 is a longitudinal sectional view seen from the side showing the structure in the vicinity of an air outlet 132a for drying of a conventional washing and drying machine.
Conventionally, washing of laundry such as clothes by a washing / drying machine is performed by using a high-temperature and low-humidity drying air flow generated by a blower fan and a heat source above the door 109 through a blow duct 132 as shown in FIG. The air is sent to the outlet 132a, and an air flow is blown into the washing / dehydrating tub 103 through the outlet 132a (arrow α10 in FIG. 8) to evaporate the moisture from the laundry and to discharge the evaporated moisture to the outside of the machine. It is done by.

As a method for removing moisture evaporated from the laundry, an exhaust system in which the air containing the evaporated moisture is discharged out of the laundry dryer as it is and new air is constantly supplied, and moisture evaporated from the laundry is included. There is a dehumidification method in which the air is cooled and condensed to dehumidify and the same air is circulated in the washing / dehydrating tank 103.
In home-use washing and drying machines, a dehumidification system that does not discharge moisture into the room is often used in order to prevent an increase in humidity in the room where the washing and drying machine is installed.

The washing and drying machine is required to have a short drying time, low power consumption, a good finish of drying (less wrinkles of laundry such as clothes), and less damage to the laundry.
Among these, with regard to the finish with good drying, there are some laundry dryers in which the wrinkles of the laundry are generated by the tangling or twisting of the laundry during the drying, and therefore the tangling or twisting of the laundry is less likely to occur.

JP 62-44299 A JP-A-9-774 JP-A-2005-080946 JP 2002-346272 A

  By the way, even if there is no tangling or twisting of the laundry, if the amount of laundry such as clothes increases with respect to the volume of the washing / dehydrating tub 103, the laundry cannot be sufficiently spread, so the laundry is bent. It is dried as it is and wrinkles occur. On the other hand, the larger the volume of the washing / dehydrating tank 103, the more laundry such as clothes can be spread.

However, in home-use washer / dryers, the size of the washer / dryer is limited due to the limitation of the area of the installation location and the import path (corridor and door) to the installation location. It is difficult.
For this reason, laundry such as clothes that care about the finish of drying is separated from other general laundry, and there is only a method of drying by reducing the amount of laundry such as clothes. However, it is not realistic to perform time-consuming drying a plurality of times, and laundry such as clothes is dried by hanging, and the dryer is not used.

FIG. 9 is a longitudinal sectional view, seen from the side, showing the structure in the vicinity of the air outlet 232d for drying of another conventional washing and drying machine.
Therefore, as shown in FIG. 9, a blowing duct 232 having a small opening area of the blowing port 232 d toward the center of the washing / dehydrating tub 203 is provided above the door 209, and a high temperature is discharged from the narrow blowing port 232 d of the duct 232. A high speed warm air is blown into the washing / dehydrating tub 203, directly blown onto the laundry (arrow α11 in FIG. 9), and a laundry dryer that stretches and dries the wrinkle of the laundry has appeared.

The door glass 209g is formed with a glass peripheral plate 209g1 and a glass back plate 209g2 formed continuously from the glass peripheral plate 209g1 and projecting in a convex shape toward the washing / dehydrating tub (drum) 203 side.
However, this type of washing / drying machine aims to improve the finish such as reducing wrinkles after drying the laundry, and the direction of the hot air outlet 232d is directed to the laundry directly. There is no warm air that directly hits the side plate 209g1, the door 209, and the bellows 200 that seals the outer tub 202 with water.

  Therefore, in the drying process, evaporation of water droplets remaining on the glass peripheral side plate 209g1 of the door glass 209g and the bellows 200 is slow, and lint such as lint of laundry that is generated during drying is applied to the glass peripheral side plate 209g1 and bellows 200 of the door glass 209g. Since it adheres to the remaining water droplets and is dried as it is, the lint is fixed, and the phenomenon that the lint remains on the glass peripheral plate 209g1 and the bellows 200 at the end of the drying occurs.

That is, the glass back plate 209g2 of the door glass 209g formed in a convex shape toward the washing / dehydrating tub 203 is always in contact with the laundry, so that lint does not easily adhere, but the glass peripheral side plate 209g1 and the bellows 200 are Since external force does not work and warm air is not blown in, a phenomenon occurs that lint is difficult to remove once attached.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a washing / drying machine and a drying machine that can prevent lint such as lint from adhering to doors and bellows and improve maintainability.

In order to achieve the above object, a dryer according to the first aspect of the present invention includes an outer tub having an opening through which laundry is taken in and out, a rotational motor installed in the outer tub and driven by a motor, and at the opening of the outer tub. comprising a tank for laundry having an opening opposing is accommodated, and a door for opening and closing the opening of the outer tub, and a drying mechanism with fan, and a drying duct, the door of the inner tub A dryer having a first window plate portion that protrudes toward the opening and a second window plate portion that is continuously formed around the first window plate portion, wherein the drying is performed during a drying operation. Dry blowing means for directly blowing the wind generated by the mechanism and flowing through the drying air path onto the laundry contained in the inner tub, and the wind generated by the drying mechanism in the middle of the air path of the dry blowing means through openings formed in, attached can spray on the second window pane unit lint removal And a means.

  The washing / drying machine according to the second aspect of the present invention performs washing and rinsing by rotating the inner tub when the washing water and the rinsing water are stored in the outer tub in the drying machine of the first aspect of the present invention. Has a washing function.

The blower unit 28 shown in FIG. 2 includes a fan impeller (not shown) for creating an air flow for drying, a fan case 28b, and a fan motor 28a for driving the fan impeller.
The fan case 28b incorporates a heater 31 (see FIG. 4) that heats the air sent from the fan impeller.

As shown in FIG. 4, the discharge port of the blower unit 28 is connected to a warm air duct 30. The warm air duct 30 is made of a rubber bellows tube 30a and a bellows tube joint 30b (see FIGS. 2 and 5). Is connected to the hot air blowing air passage 32 provided in the outer tank cover 2d.
A temperature sensor (not shown) is provided at the intake port and the discharge port of the blower unit 28.

In the present embodiment, as shown in FIG. 2, since the air blowing unit 28 is provided on the upper right side in the housing 1k, the hot air blowing air passage 32 is provided at a position on the upper right side of the outer tank cover 2d, The distance from the unit 28 to the hot air blowing air passage 32 is made as short as possible.
The drum-type washing and drying machine 1 directly applies high-speed wind to laundry such as clothes and stretches wrinkles generated in the laundry such as clothes by the force of the wind. A hot air blowing air passage 32 for directing the wind directly onto the laundry.

<Hot air blowing air path 32>
Next, details of the hot air blowing air passage 32 will be described.
5 is provided along the opening 2c of the outer tub 2 from the front side of the outer tub cover 2d of the outer tub 2 (see FIG. 6).
As shown in FIG. 6, the hot air blowing air passage 32 has flow paths 32 b and 32 c formed therein, and a bellows pipe joint 30 b is attached to the inlet 32 e of the hot air blowing air passage 32. A nozzle 32d (see FIG. 5) is formed at the outlet of 32c.

As shown in FIG. 6, the inner diameter of the opening 2 c of the outer tub cover 2 d and the opening of the washing and dehydration tub 3 are prevented so that clothing does not enter between the washing and dehydration tub 3 and the outer tub cover 2 d of the outer tub 2. The inner diameter of 3a is set almost the same.
And as shown in FIG. 5, the exit part 32a of the warm air blowing air path 32 protrudes inwardly from the inner peripheral surface of the opening part 2c, and as shown in FIG. 3 is formed so as to open toward the inside, and the warm air (arrow β1 in FIG. 6) from the nozzle 32d directly hits the laundry in the washing and dewatering tub 3.

  In addition, when there is too much jumping-out amount from the opening part 2c of the outer tank cover 2d of the exit part 32a, there exists a possibility of inhibiting the movement of laundry, such as clothing, at the time of washing or drying. Therefore, as shown in FIG. 5, the nozzle of the outlet part 32a is formed into a flat slit shape, the amount of protrusion of the outlet part 32a is reduced, and as shown in FIG. The surface shape of the outlet portion 32a of the blowing air passage 32 is configured to change smoothly.

Further, the flow path 32b and the flow path 32c of the hot air blowing air path 32 shown in FIGS. 5 and 6 are configured so that there is no useless protrusion or a sudden change in the air flow direction, and the flow path toward the nozzle 32d. The area is gradually reduced.
As a result, pressure loss and fluid noise generated when high-speed drying air flows through the flow paths 32b and 32c are reduced.

<Lint removal outlets 32f1, 32f2 in the hot air outlet 32>
The hot air outlet path of the hot air outlet 32 is a main stream that flows directly from the flow paths 32b and 32c to the laundry following the nozzle 32d, and branches as a branch in the middle of the main path. A multipath is formed, and the tributary flow is a flow in which hot air is applied from the inside to the glass peripheral side plate 9g1 of the door glass 9g.
Thus, the tributary of the hot air outlet path blows lint such as lint attached to the glass peripheral side plate 9g1 and the bellows 10 of the door glass 9g by wind pressure, and the water droplets remaining on the glass peripheral side plate 9g1 and the bellows 10 Promotes evaporation.

Specifically, as shown in FIG. 6, lint such as lint attached to the glass peripheral side plate 9 g 1 of the door 9 and the bellows 10 is removed from the hot air blowing air passage 32 at a location facing the flow passage 32 b. Two lint removal outlets 32f1 and 32f2 (refer to FIG. 5) are opened.
These two lint removal outlets 32f1 and 32f2 (see FIG. 5) are formed so as to penetrate in the direction of the wind flowing in the flow path 32b (the direction of warm air).
The two lint removal outlets 32f1, 32f2 are separated from each other substantially symmetrically with respect to the center line c of the flow paths 32b, 32c shown in FIG. 5, and along the circumferential direction of the glass peripheral side plate 9g1 of the door glass 9g. It is formed in the position.

Here, the ratio of the opening area of the lint removal outlets 32f1 and 32f2 (see FIG. 5) to the opening area of the nozzle 32d is approximately 1:20.
Thus, by reducing the opening area of the lint removal outlets 32f1 and 32f2 relative to the opening area of the nozzle 32d, the hot air is blown from the lint removal outlets 32f1 and 32f2. It is possible to suppress a decrease in the drying performance of the laundry S due to the blowing of warm air.
The ratio between the opening area of the lint removal outlets 32f1 and 32f2 (see FIG. 5) and the opening area of the nozzle 32d depends on the amount of air flowing through the flow paths 32b and 32c and the air speed, but is a washing and dewatering tank. In order to improve the finish of drying of the laundry S in No. 3, a wind speed of 95 to 100 m / s applied directly to the laundry S from the nozzle 32d is required. Therefore, the following knowledge has been obtained by setting the wind speed directly applied to the laundry S from the nozzle 32d to 95 to 100 m / s.

For example, the opening area of the lint removal outlets 32f1 and 32f2 in the tributary path in the hot air outlet 32 shown in FIGS. 5 and 6 is about 5% (about 14 mm) of the opening area (275 mm ² ) of the mainstream nozzle 32d. ² and having 2 holes each having a diameter of 3 mm, a good lint adhesion suppressing effect can be obtained.
Here, in order to improve the finishing of the laundry S in the washing and dewatering tub 3, the wind speed from the main nozzle 32d needs to be 95 to 100 m / s. open area fraction of (14 mm ²⁾ reduces the opening area of the main stream of the nozzle 32d, and a 261 mm ^2. In this case, the opening area of the outlet 32f1,32f2 a lint removal (14 mm ²⁾ is about 5.4% open area of the nozzle 32d (261mm ^2).

<Flow of warm air during drying operation>
The flow of warm air from the drying mechanism during the drying operation by the control device 38 (see FIG. 2) is as follows.
When the air blowing unit 28 shown in FIG. 2 is operated and the heater 31 (see FIG. 4) is energized, as shown by the arrow β1 in FIG. Hot air blows in. At the same time, as indicated by an arrow α4 in FIG. 6, warm air is blown out from the lint removal outlets 32f1 and 32f2 (see FIG. 5) and the glass peripheral side plate 9g1 of the door 9 is indicated by arrows α51 and α52 in FIG. 1 and flows along the circumference of the glass peripheral side plate 9g1 of the door 9 as indicated by arrows α71 and α72 in FIG.

As a result, warm air blown from the nozzle 32d into the washing and dewatering tub 3 (see arrow β1 in FIG. 4) hits the wet laundry S, warms the laundry S, and moisture evaporates from the laundry S.
Also, the warm air blown out from the lint removal outlets 32f1 and 32f2 flows through the glass peripheral side plate 9g1 of the door 9 (arrows α51 and α52 in FIG. 6, arrows α71 and α72 in FIG. 1), and the glass peripheral side plate 9g1 of the door 9 and The lint adhering to the bellows 10 is blown away, and the evaporation of water adhering to the glass peripheral side plate 9g1 and the bellows 10 is accelerated by the wind pressure and heat of the hot air, and the adhesion of lint to the glass peripheral side plate 9g1 and the bellows 10 is suppressed. The

In this way, the air that has removed the moisture of the laundry S and evaporated the moisture adhering to the glass peripheral side plate 9g1 and the bellows 10 to become hot and humid flows from the small through hole provided in the washing and dewatering tub 3 to the outer tub 2. 4 and 3, the air is sucked into the drying duct 29 from the air inlet 2 a and flows through the drying duct 29 from the bottom to the top.
Cooling water flows down on the wall surface including the water cooling and dehumidifying mechanism inside the drying duct 29, and the hot and humid air is cooled and dehumidified by coming into contact with the cooling water to become dry low temperature air, which is indicated by an arrow β2 in FIG. As shown, it enters the filter duct 27.

Then, as shown by the arrow β3 in FIG. 2, the lint is removed through the mesh filter 8a provided in the filter duct 27 and enters the intake duct 33 as shown in FIG. 4, as shown by the arrow β4 in FIG. Then, it is sucked into the blower unit 28.
Then, it is heated again by the heater 31 shown in FIG. 4, and blown again into the washing and dewatering tub 3 from the nozzle 32d (arrow β1 in FIG. 4), and as shown by the arrow α4 in FIG. The hot air circulates through the glass peripheral side plate 9g1 of the door 9 from 32f1 and 32f2.

<Effects of lint removal outlets 32f1, 32f2>
As described above, the two lint removal outlets 32f1 and 32f2 (see FIG. 5) are formed so as to penetrate in the direction of the wind flowing in the passage 32b. As is clear from FIG. 6, the warm air that travels through 32b is blown out from the lint removal outlets 32f1 and 32f2 with a small loss, as shown by the arrow α4 in FIG. 6, and blows against the glass peripheral side plate 9g1 of the door 9. It flows on the glass peripheral side plate 9g1 as indicated by arrows α51 and α52 in FIG.

Also, as shown in FIG. 5, the two lint removal outlets 32f1, 32f2 are formed at positions along the circumferential direction of the glass peripheral side plate 9g1 so as to be separated from each other. The hot air thus flowed flows on the glass peripheral side plate 9g1 as indicated by an arrow α71 in FIG. 1, and the hot air blown out from the lint removal outlet 32f2 flows as indicated by an arrow α72 in FIG.
As a result, lint such as lint on the glass peripheral side plate 9g1 and on the bellows 10 is blown off, and moisture adhering to the entire glass peripheral side plate 9g1 and the entire bellows 10 is accelerated by heat and air flow, Adhesion of lint such as lint to the glass peripheral side plate 9g1 and bellows 10 can be effectively suppressed.

  Further, as described above, the lint removal outlets 32f1 and 32f2 (see FIG. 5) are used to reduce the wind speed from the nozzle 32d to the laundry S, and the opening area of the nozzle 32d is reduced to the lint removal outlets 32f1 and 32f2. The wind speed from the nozzle 32d can be secured by reducing the opening area.

<< Modified form of lint removal outlet >>
FIG. 7 is a cross-sectional enlarged view taken along the line BB in FIG. 5 of the modified embodiment, and is a cross-sectional view of the hot air blowing air passage 32 of the modified embodiment.
As shown in FIG. 7, the modified hot air blowing air passage 32 has the lint removal outlets 42f1, 42f2 changed from the positions of the lint removal outlets 32f1, 32f2 of the embodiment shown in FIG. Formed.
Since the other configuration is the same as that of the above-described embodiment, the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  Specifically, the lint removal blowout ports 42f1 and 42f2 in the modified hot air blowout air passage 32 penetrate in a direction different from the direction of the wind (warm air) in the flow path 32c, and the lint removal blowout airflow. The angle θ with respect to the glass peripheral side plate 9g1 of the door 9 on the near side (left side of the central axis c1 in FIG. 7) of the central axis c1 of the ports 42f1, 42f2 with respect to the outer side region of the glass peripheral side plate 9g1 is 90 degrees. It is formed to be inclined so as to have the above obtuse angle.

In this manner, the lint removal outlets 42f1 and 42f2 penetrate in a direction different from the direction of the wind of the flow path 32c, so that the amount and speed of the air blown from the lint removal outlets 42f1 and 42f2 are changed to the flow path 32c. It is possible to reduce the amount compared to the case of forming a through-hole in the direction of the wind (warm air).
Accordingly, the lint removal outlets 42f1 and 42f2 are formed so as to penetrate in a direction different from the direction of the wind of the flow path 32c when the air flow rate and the wind speed of the flow paths 32b and 32c of the hot air blowout air flow path 32 are large. Thus, it is possible to apply hot air to the glass peripheral side plate 9g1 of the door 9 while reducing the air volume and the wind speed.
Therefore, when the blowout air volume and air velocity from the lint removal outlets 42f1 and 42f2 are large, for example, when the noise from the lint removal outlets 42f1 and 42f2 is high, the air volume and wind speed are reduced to suppress noise. it can.

  Also, as shown in FIG. 7, the lint removal outlets 42f1, 42f2 are formed so as to be inclined so that the angle θ of the central axis c1 of the central axis c1 with respect to the outer side region of the glass peripheral side plate 9g1 becomes an obtuse angle of 90 degrees or more. Then, the warm air blown out from the lint removal outlets 42f1, 42f2 is guided on the glass peripheral side plate 9g1 of the door 9 as shown by the arrow α6, and the lint of the glass peripheral side plate 9g1 and the lint of the bellows 10 are blown off. At the same time, it is possible to promote the evaporation of water adhering to these locations, and to effectively suppress the adhesion of lint to the glass peripheral side plate 9g1 of the door 9 and the bellows 10.

Similarly to the embodiment, the opening area of the lint removal outlets 42f1, 42f2 of the hot air outlet path 32 is set to about 1/20 of the opening area of the nozzle 32d, and the nozzle 32d and the lint removal outlet 42f1, The hot air blowing from 42f2 is secured.
For example, after the ratio of the opening area of the branch lint removal outlets 42f1 and 42f2 in the warm air outlet 32 and the opening area of the main nozzle 32d is 1/20, the opening area of the nozzle 32d is used for lint removal. The air velocity from the nozzle 32d is secured by reducing the opening area of the air outlets 42f1, 42f2, and the air volume from the nozzle 32d is set to 1.52 m ³ / min (min) and the air velocity is 96 m / s (second), and the lint is set. The air volume from the removal outlets 42f1, 42f2 is set to 0.08 m ³ / min (min) and the wind speed is 96 m / s (sec).

Alternatively, when the warm air flowing through the flow paths 32b and 32c has a wind speed of 96 m / s and an air volume of 1.6 m ³ / min, the lint removal outlets 42f1 and 42f2 of the added tributary path are the opening areas of the mainstream nozzle 32d. The effect was confirmed with an opening area of about 5% (≈5.09%) of (275 mm ² ) (about 14 mm ² , 2 holes with a diameter of 3 mm).

Further, the lint removal outlets 42f1 and 42f2 of the tributary path have about 3% (≈2.9%) (about 8 mm ² , diameter 2.3 mm holes) of the opening area (275 mm ² ) of the mainstream nozzle 32d. The effect was confirmed even with the opening area of). In addition, if it reduces from about 3%, an effect will become less and the amount of lint (dust) adhesion will increase.
From the above, it is considered that the desired effect can be obtained when the opening area of the lint removal outlets 42f1 and 42f2 of the tributary path is about 2.5% to 6% of the opening area of the mainstream nozzle 32d.
