DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer provided with a lint collecting device for collecting lint that is separated from the clothes when the clothes are dried and collected.

[0002]

2. Description of the Related Art Rotary drum type clothes dryers include a method in which wet laundry is put in a drum, hot air is supplied into the drum while rotating the drum, and the warm air contains the moisture of the laundry. The clothes are dried by repeating a process of exhausting water from the air, condensing water vapor contained in the exhausted warm air, converting the water into water, and discharging the water outside the machine. That is,
Hot air is circulated through the rotating drum, and in the process, moisture contained in the laundry is taken in as steam, and the taken-in steam is condensed and dried. Laundry is separated from lint during the drying process and moves with the warm air.If the lint enters the circulation air path, the air path is blocked and the drying time is prolonged. Will cause problems.

[0003] Therefore, in this type of clothes dryer, a lint collecting device composed of a net filter is provided in the circulation air passage after passing through the clothes so as not to hinder the drying operation. In many cases, the lint collecting device is provided on the leeward side of the clothing, that is, at a location corresponding to a hot air outlet on the rear surface of the rotary drum. The lint collected by the lint collecting device causes pressure loss in the circulation air passage as described above, causes a decrease in the amount of circulation air, and causes a decrease in a drying function. It needs to be removed regularly.

As shown in FIG. 29, a conventionally used lint collecting device is a net filter 32 using a polyester net or the like, and a synthetic fiber or the like for collecting fine dust passing through the net filter 32. Has a double filter structure of a non-woven fabric filter 31 made of non-woven fabric, and is attached to a filter guard (also referred to as a filter cover) 33 so that clothes do not directly touch the filter surface. Will be installed. In this case,
These filters 31 and 32 are formed by a back filter 34 as shown in FIG.
That is, it is mounted inside the filter guard 33 in FIG.

[0005]

In the conventional clothes dryer having the lint collecting device constructed as described above, the lint accumulates in the filters 31 and 32. 31 had to be cleaned. Regarding this cleaning, when suction is performed by a vacuum cleaner, dust such as lint accumulated on the front surface of the net filter 32 is removed by the filter guard 3 shown in FIGS.
3, the filter guard 33 must be removed and cleaned.

That is, in the back filter 34, the dusty dust that has passed through the net filter 32 and the non-woven fabric filter 31 may be wiped about once every six months with a soft cloth moistened with water as shown in FIG. However, in the net filter 32 and the nonwoven fabric filter 31, dust removed from the filter guard 33 and sucked using a vacuum cleaner as shown in FIG. 30 or brushed as shown in FIG. An operation such as peeling off the kind is required. Therefore, it is troublesome and troublesome, and it is unsanitary because it touches the dusty filter every time. Furthermore, when the components in the detergent used for washing, the softener component, etc. remain in the clothes, or when the glued clothes are dried, both the net filter 32 and the nonwoven fabric filter 31 are in a clogged state. But it was not easy to clean.

In recent years, there are many laundry types, that is, a type in which a clothes dryer is installed through a stand above a washing machine and used, and in this type, the clothes dryer is located at a high position. Therefore, it was difficult to reach the lint collecting device at the rear of the rotating drum, making it difficult to maintain. Also,
As a result, they are often used without being cleaned. If you continue to use the clothes dryer without cleaning the filter or with severe clogging in this way, not only will the hot air flow deteriorate, you will not be able to achieve the full performance of the clothes dryer, Lint may leak into the body from the gaps in the bearings, etc., and accumulate in the motors, etc., causing the motor temperature to rise, or even cause a serious accident such as a fire. Simplification of cleaning of the lint collecting device when using the machine has been an important issue in clothes dryers.

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation of the prior art, and has as its object to provide a lint collecting device which can easily remove lint, is hygienic and has excellent usability. An object of the present invention is to provide a clothes dryer. Another object is to provide a clothes dryer that can be easily cleaned with a vacuum cleaner.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a clothes dryer which rotates a drum in which clothes are stored and supplies warm air to dry the clothes. In the clothes dryer provided with a lint collecting device for collecting the lint in a circulation air passage after passing through the clothing, the lint collecting device includes a filter for collecting the dust, a filter for supporting the filter and the recirculation. and a filter guard that is attached to the air passage
The filter guard is divided into grids by partition walls.
Was the partitioned plurality of vent paths are formed, a plurality of dust collecting chamber between said with the ventilation channel filter is formed,
The dust collection chamber opens toward a clothes removal door,
This is achieved by configuring the filter and the filter guard to be separable .

[0010] Further, as a countermeasure for a laundry type, in which the lint collecting device at the rear of the rotating drum is difficult to reach, a long dedicated suction opening substantially corresponding to the depth of the rotating drum is provided with a clothes dryer. Prepare it in the frame. In this case, the suction diameter of the suction port may be set to a diameter that can cover the entire surface of the filter guard.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view showing the structure of a clothes dryer employing a lint collecting device according to one embodiment of the present invention. In the figure, a clothes dryer includes an outer frame (machine frame) 1.
And a drum 3 housed in the outer frame 1, a drive mechanism 30 for the drum 3, a dry air supply mechanism 40 for supplying drying air into the drum 3, and a yarn discharged outside the drum 3. It mainly comprises a lint collecting mechanism 50 for collecting lint.

Inside the outer frame 1, the drum 3 has a front side via a drum support 17 attached to the outer frame front plate 1-1 of the outer frame 1, and a rear side with the outer frame 1. A drum shaft 9-fixed to a drum fan support plate 9 mounted behind
1 are rotatably mounted via drum bearings 3-1. The drum 3 stores clothes and stirs the clothes. The stirring is performed by attaching the motor base 4-1 to the outer frame 1.
By means of a motor 4 mounted via That is, the rotation of the motor 4 is transmitted via the drum belt 15 which is tensioned by the drum driving pulley 4-2 and the tension applying pulley 13. On the front surface of the outer frame body front plate 1-1, a door 2, which is opened and closed when clothes are taken in and out of the drum 3, is attached by a hinge so as to be freely opened and closed.

A fan casing 8 and a fan 6 housed in the fan casing 8 are provided behind the drum exhaust port 3-2 of the drum 3. The fan casing 8 is fixed to the drum / fan support plate 9, and the fan 6 is rotatably supported by a fan shaft 9-2 fixed to the drum / fan support plate 9. The fan 6 is driven by the motor 4 via a fan drive pulley (not shown) attached to the motor 4 and a fan belt 10.

The fan casing 8 comprises a fan 6 and a partition plate 7
Thus, the front side and the back side are partitioned into a circulation side A and a cooling side B. On the circulation side A, air in the drum 3 is circulated. On the cooling side B, outside air is introduced from a back plate intake port 14-1 provided on a back plate 14 covering the rear surface of the outer frame 1, and a back plate exhaust port is provided. It is a so-called heat exchange type of a front and back wing type that discharges air from 14-2. The air sucked by the fan 6 and supplied into the drum 3 from the circulation side A via the circulation duct 11 is supplied to the heating element 5 located below the drum support 17 and immediately before the drum intake port 17-1.
And heated into the drum 3.

Immediately before the drum exhaust port 3-2 of the drum 3, a lint collecting device 16 for collecting dust such as lint generated from clothes in the drum 3 is installed, and a collecting net 19-1.
Is detachably attached to a filter support base 19 having

As shown in the exploded sectional view of FIG. 6 and the sectional view of the assembled state of FIG. 7, the lint collecting device 16 includes a filter guard 16-1, a net filter 16-2, and a nonwoven fabric filter 1.
6-3.

The filter guard 16-1 is shown in FIGS.
The front view and the cross-sectional view of the filter guard, and the net filter 16-2 along the outer periphery on the back side as shown in FIG.
Is formed, and a partition wall 16-1-1 is formed on the front side in a ridge shape. This partition wall 16
The portion surrounded by -1-1 is open front and rear, serves as a ventilation path through which circulating air flows, and functions as a dust collection chamber when combined with the net filter 16-2. The partition wall 16-1-1 comprises a wall portion 16-1-1-1 formed in an annular shape at equal intervals from the center, and a wall portion 16-1-1-2 extending radially from the center in the radial direction. As can be seen from FIG. 3, the taper is formed such that the width of the rear side becomes slightly narrower. This is in consideration of die cutting and dust collection. In addition, the partition wall 16-1-1,
It is formed substantially perpendicular to the net filter 16-2 in consideration of the ease of cleaning the collected dust. With this configuration, since the entire surface of the filter guard 16-1 is partitioned in a grid by the partition wall 16-1-1, the strength is increased, and the width of the partition wall can be reduced to 1.5 mm or less. The room can be large.

The radial wall portion 16-1-1-2 of the partition wall 16-1-1 is not made continuous as shown in FIG. 2, but as shown in FIG. Part 16-
When formed so as to be staggered with respect to 1-1-1 as a boundary, the interval between the radial wall portions 16-1-1-2 adjacent to each other with the circumferential wall portion 16-1-1-1 interposed therebetween is reduced. Since it becomes narrower, the strength can be further increased. As a result, the width of the partition wall 16-1-1 can be further reduced, and the dust collection chamber can be further increased.

As shown in the front view of FIG. 4 and the sectional view of FIG.
16-2-3 and receiving portion 16-2 elastically engaged with
-1 is integrally formed, and a polyester net 16-2-2 is stretched between the receiving portions 16-2-1. The receiving portion 16-2-1 is provided at a position corresponding to the partition wall 16-1-1 of the filter guard 16-1 on the back surface of the frame 16-2-3. In this embodiment, a polyester net is illustrated, but any other synthetic resin formed in a net shape may be used. However, heat resistance enough to withstand warm air for drying is necessary. Further, the filter guard 16-1 and the net filter 16-2 can be integrally formed so as to be inseparable. However, in consideration of the substance of the cleaning, there is a case where the lint collecting device 16 is detached and cleaned. In this case, the work is easier if the net filter 16-2 can be separated from the filter guard 16-1.

The nonwoven fabric filter 16-3 is made of a nonwoven fabric made of synthetic fiber having an appropriate thickness.
As can be seen, the frame 16- of the net filter 16-2
It is mounted on the back of 2-3. As shown in FIG. 7, the lint collecting device 16 in which the respective portions are formed is provided with the frame 16-2 of the net filter 16-2 on the mounting portion 16-1-3 on the back surface of the filter guard 16-1. -3 is elastically engaged, and the receiving portion 16-2-2 is brought into contact with the rear surface of the partition wall 16-1-1. As a result, the space separated by the partition wall 16-1-1 and the net 16-2-2 becomes the dust collection chamber 16-1-2 which was touched before.

Returning to FIG. 1, the main structure of the clothes dryer will be described. The casing discharge port 8-1 and the drum intake port 17-1 of the fan casing 8 are connected to a circulation duct 11 having a drain port 11-1 on the way. And in front of the circulation duct 1
2 are connected in a state where airtightness is maintained. Thus, the air in the drum 3 is transferred from the drum 3 to the lint collecting device 1.
6 → drum exhaust port 3-2 → fan casing 8 (circulation side A) → casing discharge port 8-1 → circulation duct 11 → front of circulation duct 12 → heating element 5 → drum intake port 17-1 (hot air outlet) → The air circulates like the drum 3, and a circulation air path circulating in this order is formed.

Reference numeral 18 denotes a control device for controlling the operation of the motor 4, the heating element 5 and the like, and is attached to the outer frame front plate 1-1 via a panel 18-1. The partition plate 7 has a so-called labyrinth seal structure. In the case of this embodiment, the labyrinth seal structure is such that a rib having a comb-shaped cross section integrally provided on the outer periphery of the fan 6 and a rib having a comb-shaped cross section provided on the partition plate 7 are mutually incompatible. Refers to a configuration in which projections and depressions are engaged in a contact state.

In operation of the clothes dryer constructed as described above, first, the motor 4 and the heating element 5 are energized, the motor 4 starts rotating, the drum 3 and the fan 6 are respectively driven to rotate, and the heat is further generated. The body 5 generates heat and the warm air is supplied into the drum 3, and the stored clothes are agitated and the drying operation is performed.

The moisture evaporating from the clothes passes through the lint collecting device 16 together with the circulating wind, and flows into the circulation side A of the fan casing 8 through the drum exhaust port 3-2. Also back plate 14
Outside air flows into the cooling side B of the fan casing 8 from the back plate intake port 14-1, and is exhausted from the back plate exhaust port 14-2. In the outer peripheral portion of the fan 6, the circulating air and the cooling air are separated by a labyrinth seal portion with the partition plate 7 without entering and exiting. Here, the circulation side A and the cooling side B of the fan casing 8 on the front and back of the fan 6. Heat exchanged between
Moisture contained in the circulating wind is condensed and becomes water, which flows from the casing discharge port 8-1 of the fan casing 8 to the circulating duct 1.
1 and is discharged out of the machine through the drain port 11-1.
Thus, a series of drying operations of the clothes dryer are continued.

In this series of drying steps, dust such as lint generated from clothes in the tram 3 is collected by the lint trap 16 and thereafter does not enter downstream of the circulating wind. That is, dust such as lint flows into the lint collecting device 16 together with the circulating wind, is captured by the net filter 16-2-2, and is deposited in the dust collection chamber 16-1-2. Fine dust is also captured by the lint accumulated in the dust collection chamber 16-1-2.

When the drying operation is completed and the lint collecting device 16 is to be cleaned, the lint collecting device 16 is mounted on the filter support base 19 as shown in the explanatory view of FIG. The suction port 20 may be brought to the front of the lint collecting device 16 and the lump C of lint collected in each dust collecting chamber 16-1-2 may be sucked. Normally, such a cleaning method is sufficient. However, as the operation is repeated, fine dust passing through the net filter 16-2 is removed.
-3, and the drying time may be prolonged. In this case, the lint collecting device 16 may be removed from the filter support 19, and the nonwoven fabric filter 16-3 may be removed and individually cleaned. However, this depends on the state of use, but once every several tens of times is sufficient, and the labor of cleaning can be greatly reduced as compared with the related art.

In this embodiment, the partition 16-1
-1 and the receiving portion 16-2-1 are configured to be in contact with each other, but since the lint and the like accumulated in the dust collecting chamber 16-1-2 are sucked by the vacuum cleaner, the partition wall 16-1-1. The distance between the first portion 1 and the receiving portion 16-2-1 only needs to be such that lint can be cut in each dust collecting chamber 16-1-2. Therefore, any configuration may be used as long as the lint lump C is cut by the partition wall 16-1-1 even if a gap of 0.5 to 1 mm is generated. If there is a gap, if there is a risk that the vacuum cleaner will not cut due to the output, each dust collecting chamber 16-
1-2 needs to be configured to be completely independent of the adjacent dust collection chamber 16-1-2. As an independent configuration, the filter guard 16-1 and the net filter 16-2 may be formed integrally as described above, or as shown in the front view of FIG. 10 and the cross-sectional view of FIG.
A recess 16-2-1-1 is formed in the receiving portion 16-2-1 of the filter guard 16 as shown in the exploded view of FIG.
The rear end 16-1-1-3 of the -1 partition wall 16-1-1 is fitted into the recess 16-2-1-1, and the two are elastically engaged with each other as shown in the assembly sectional view of FIG. It may be configured to match.

FIG. 14 is a front view, and FIG.
As shown in the line sectional view, the frame 1 of the net filter 16-2
A projection 16-2-1 having an L-shaped cross section is provided at the rear end of the yoke of 6-2-3.
17 and the rear end 16-1-1-3 of the same filter guard as described above as shown in the exploded sectional view of FIG.
As shown in the assembly drawing of FIG.
A configuration may be employed in which the two are elastically fitted to the protrusions on which the protrusions are formed, and the two are brought into close contact with each other.

In any case, the close contact between the partition wall 16-1-1 and the receiving portion 16-2-1 becomes more reliable, and the dust collecting chamber 1
Dusts such as lint can be independently accumulated in 6-1-2. In addition, the above-mentioned concave part 16-2-1-1 or L
The character-shaped projection 16-2-1-2 is determined in consideration of a required area set in the net 16-2-2, and further in consideration of productivity in mold production and collection performance. It should be noted that the net 1 is not attached to the partition wall 16-1-1 without taking such an elastic engagement structure.
6-2-2, the rear end 16-1-1-3 of the partition wall 16-1-1 is protruded as shown in an exploded sectional view of the filter guard and the net filter in FIG. As shown in the assembly cross-sectional view of FIG. 19, when the net filter 16-2 is attached, the net 16-2-2 may be deformed by its own elasticity and may be brought into close contact with an appropriate tension. However, in this case, it is necessary to properly set the elastic force of the net 16-2-2 and the protrusion amount of the partition wall 16-1-1.

If the net 16-2-2 does not have elasticity, the shape cannot be set as shown in FIG. If the above-described concave portion or L-shaped protrusion is formed in the receiving portion 16-2-1, it is considered that the collection area is reduced and the collection efficiency is deteriorated. As shown in the cross-sectional views of FIG. 21 and FIG. 21, a rib 19-2 as a frame is provided at a position corresponding to the partition wall 16-1-1 of the filter guard 16-1, and the filter 19-1 is provided between the ribs 19-2. Can be introduced. When the filter support 19 is configured in this manner, the partition wall 1 is formed as shown in the sectional view of FIG.
6-1-1 Between the rear end 16-1-1-3 and the tip of the rib 19-2, the net 16-2-2 and the nonwoven fabric filter 16-
3 are sandwiched, and the dust collecting chamber 16-1-2 and the net 16-2-
There is no gap between the two.

In this embodiment, dust such as lint collected in the lint collecting device 16 is suctioned and cleaned by a vacuum cleaner. In this case, the clothes dryer is installed at a high position above the washing machine 24, so that the suction opening may not easily reach the deep portion of the drum 3. However, a storage part 25 for storing the suction port 21 having a long cylindrical tip is provided at a part of the outer frame body 1 of the clothes dryer, in this embodiment, at the bottom, and the suction port 21 is inserted into the storage part 25 so that it can be taken out from the front. If stored as an attachment, the mouthpiece can be replaced and cleaned as needed. For this reason, the dedicated suction port 21 having a long cylindrical end is connected to the filter guard 16-1 of the lint collecting device 16 from the opening of the outer frame body front plate 1-1 provided with the door 2.

It is also possible to suck all the dust accumulated in each dust collecting chamber 16-1-2 at once without moving the tip of the suction port 21 to each dust collecting chamber 16-1-2.

As shown in FIGS. 33 and 34, the shape of the filter guard dust collecting chamber 16-1-2 of the lint collecting device 16 is made slightly larger than the outer shape of the suction port 20.
If the suction port 20 is inserted into the dust collection chamber 16-1-2 and sucked, the operation is slightly more troublesome than the suction port 20 formed slightly larger than the opening of the dust collection chamber 16-1-2 shown in FIG. However, the suction force is not dispersed and one dust collection chamber 16-1
-2, so that the amount of leftover yarn waste is reduced. In the case of the method in which the suction port 20 is inserted into the dust collection chamber 16-1-2, the shape that can be easily fitted is a cylinder (circle).

As shown in the sectional view of FIG. 24, the exclusive suction port 21 has a taper 21-3 so that the suction side (downstream in the suction direction) is narrowed, and a net filter 21-4 is formed at the base end. Is provided, the dust sucked from the lint collecting device 16 is collected by the net filter 21-4. Therefore, when cleaning is completed,
If 1 is removed and inverted on a trash box as shown in FIG. 25, the collected dust including lint can be discarded as it is. Also, if the taper 21-3 is reversed as shown in FIG. 26 and the net filter 21-4 is made detachable, when the cleaning is completed, the suction port 2 as shown in FIG.
1 can be inverted to remove the net filter 21-4, brought to the trash can and easily discarded. If the net filter 21-4 is provided at the base of the suction port 21 as described above, the sucked lint and the like are mostly accumulated in the net filter 21-4. Is economical without accumulation.
