Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a rotating drum type clothes dryer for general household use, and more particularly to an improvement in a lint collecting device.

Conventional Structure and Problems Conventional clothes dryers of this type have a structure in which a drum containing clothes is rotated, and warm air heated by a heater is supplied into the drum and exhausted through an exhaust passage. has been done. Then, the net installed in the exhaust path collects the lint coming out of the clothes (if the lint accumulates on the net, it creates resistance to the air flow, reduces the volume of hot air supplied to the drum, and slows down the drying speed. As a result, the drying efficiency and rate decrease rapidly.

For this reason, it is necessary to clean the lint from the net every time the dryer is used, but in reality, the dryer is often used without being cleaned, resulting in poor drying efficiency.

Purpose of the Invention The present invention solves the conventional problems such as: By automatically removing the lint that has accumulated in the net, it is not necessary to clean the lint every time, and the deterioration of drying efficiency is avoided. This is to prevent

Structure of the Invention The present invention comprises a lint collecting device disposed in an exhaust passage consisting of a lint collecting net and a lint collecting net surrounding the lint collecting net. lint on the collection net is moved to the lint collection net side.

Description of examples FIG. 1 shows the overall structure of a clothes dryer according to the present invention.

Reference numeral 1 denotes a main body in which a drum 2 is rotatably provided, a lid 4 for opening and closing a clothes input port 3 is provided on the front, and a front plate 6 is airtightly closed inside with a backing 5 interposed therebetween. The front plate 6 has an exhaust lower on the rear surface, and a drum support provided on the drum side at the outer peripheral edge slidably supports the sheet 8. On the other hand, a heater mounting plate 10 is fixed to the rear of the main body 1 by a support plate 9, and a heater support fitting 12 supporting the heater 11 with an insulating material and a bearing fitting having a bearing 13 are mounted on the heater mounting plate 10. 14 is provided at the rear of the drum 2 by means of a bearing 13, and a shaft 15 is rotatably supported. 16
is a backing provided on the outer peripheral edge of the heater number board 10,
It slides into contact with the drum 2 and airtightly seals the gap between the two.

Air intake ports 17 and 1 on the main body and heater plate 10, respectively.
8, and the air flowing in from these intake ports (d
It is heated by the tram 11 and supplied into the drum from the intake port 19 of the tram 2.

20 is an exhaust pipe connected to the 1iF air 1]7 of the front plate 6, a lint collecting device 21 is provided close to the exhaust 07, and a fan 22 is arranged in the middle. A motor 23 drives the fan 22, and a bell 25 for rotating the drum 2 is attached to the pulley 24 of the motor.

In this clothes dryer, the drum 2 is rotated by driving the motor 23, and the fan 22 is activated, and the air sucked in from the rear intake port is heated by the heater 11 and becomes warm air to the tram 2. being sucked inward. Clothes are dried in this warm air (d l-ram) and discharged from the exhaust lower of the front plate 6 to the outside through the exhaust pipe 2o.Then, the lint coming out from the clothes is collected by the lint collecting device 21. Ru.

Next, the lint collecting device will be explained with reference to FIGS. 2 and 3.

Reference numeral 26 denotes a net support, which has a ring-shaped frame piece 27 in the center, a frame piece 28 on the outside thereof, and has a handle 30 on the top with a protrusion 29 for fixing to the front plate 6. A circular lint collecting net 31 is attached to the piece 2A, and a ring-shaped lint collecting net 32 is attached between the frame pieces 2 and 28 with the exhaust port T side being concave. The net support 26 is inserted into the exhaust pipe 20 through the insertion opening 33 provided in the front plate 6, the protrusion 29 is fitted into the retaining hole 34 of the front plate, and the lower end is inserted into the exhaust pipe 20 through the insertion opening 33 provided in the front plate 6. It is fixed by coming into contact with the inner protrusion 35. At this time, the insertion port 33 is closed by the handle 30.

Reference numeral 36 denotes a blade, and a cylindrical boss portion 37 provided at the center thereof is fixed to the front plate 6 and rotatably mounted on the sides of the shaft 3. 39
The spring is inserted between the seat 40 provided at the end of the shaft 38 and the closed surface of the boss portion 37, and the blade 36 is inserted into the collection net 31.
It is biased in the direction away from. Note that in this example ((−
The sizes of the net 31 and the blades 36 are approximately the same as the exhaust lower formed by a large number of ventilation holes.

Next, this operation will be explained.

After drying the clothes, the warm air supplied into the tram 2 is transferred to the exhaust pipe 2 from the air-loss lower part of the front plate by the suction force of the fan 22.
The lint that enters the lint and comes out of the clothes is collected by the net 31. On the other hand, the vane 36 receives the wind pressure and compresses the spring 39 and rotates. In this state, the blade 36 rotates in contact with the Neno 1-31, so the lint collected on the Neno 1-31 is pushed out to the outer periphery by the blade 36, and is accumulated on the collecting Neno 1-32 by wind pressure. Ru. Since the net 32 has a concave surface on the exhaust port γ side, it can hold a considerable amount of lint.

If the lift accumulated in the net 32 exceeds a certain amount,
The handle portion 30 of the net support 26 may be removed from the exhaust pipe by hand and cleaned. At this time, the blade 36 is
Since the net is separated from the net due to the pressure of the net, there is no problem in inserting or removing the net.

In the above example, the air that has absorbed moisture within the drum is initially discharged to the outside, but it may also be circulated to the heater side again for dehumidification.

Effects of the Invention As described above, according to the present invention, the lits on the lint collection net are removed by the blades that automatically rotate during drying, so there is no inconvenience such as limiting the amount of ventilation of the lint collection net. , without reducing drying efficiency. It's sweet, but the lint collecting gunesoto doesn't need to be cleaned every time, so it's convenient for some users.
