Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clothes dryer, and particularly to a clothes dryer that always has stable drying performance regardless of its installation state.

Conventionally, in so-called rotary drum dryers, where clothes are placed in a rotating drum and hot air is blown to dry them, drying efficiency is improved by blowing hot air concentrated at the bottom of the rotating drum, where the clothes are always located. It has been experimentally confirmed that this is the case.

However, such dryers can be roughly divided into two types: those that are placed on the floor and those that are placed on a stand above the washing machine. It goes without saying that operating parts such as the timer knob are easier to operate when they are located at the top, and conversely, it is easier to operate these parts when they are located at the bottom.

Therefore, when placing the dryer on a stand, the dryer itself is often placed upside down compared to when placed on the floor.

However, when the drum is inverted in this way, hot air is blown from above the rotating drum, and the drying efficiency is lower than when the drum is placed on the floor, that is, when hot air is blown from below the rotating drum.

The present invention solves the above-mentioned drawbacks and changes the position of the ventilation hole to the rotating drum using a shielding plate, so that even if the dryer is turned upside down depending on the installation conditions, its performance will change. The purpose of the present invention is to provide a clothes dryer which has a high drying function and is free from drying.

The structure of the clothes dryer of the present invention includes a heat source, a fan,
A rotary drum having a cylindrical bearing part, a rotating drum driven by a motor, and a hot air intake port to the rotating drum, the hot air intake port being adjacent to a drum cover that pivotally supports the cylindrical bearing part. A shielding plate having a hot air passage hole for changing the position of the hot air blowing hole into the rotating drum is disposed adjacent to the rotary drum.

In detail, a rotating shielding plate that only partially has a hot air passage port is installed at the hot air blowing port of the rotating drum, so that hot air can only be blown into the rotating drum in one direction. Even if the main body of the dryer is reversed depending on the installation conditions, the rotating shield plate is also reversed at the same time, and the hot air passage port is located below the rotating drum. It is designed to blow warm air into it.

Next, embodiments according to the present invention will be described based on the respective figures.

Here, FIG. 1 is a schematic vertical sectional view of a clothes dryer according to an embodiment of the present invention installed on the floor, FIG. 2 is a front view thereof, and FIG. 3 is a rotating shield plate thereof. , FIG. 4 is a schematic vertical sectional view of the device shown in FIG. 1 when it is inverted and installed upside down, and FIG. 5 is a front view thereof.

First, in FIGS. 1 and 2, there is a clothes slot 2 on the front side of the outer frame 1, a door 3 pivotally supported on the outer frame 1 so as to be able to open and close the clothes slot 2, and a timer 4. A control panel 5 for controlling electrical components such as the like is arranged.

Further, legs 6 are attached to the lower part, and a back plate 8 that supports the exhaust port 7 is attached to the rear.

A drum cover 9 having an opening is disposed corresponding to the clothes input port 2 of the outer frame 1 and is supported by the outer frame 1. A heat source 10 is disposed below, and an air intake port 11 of the outer frame 1 is provided. It has come to be linked with

Further, the drum cover 9 further includes a bearing 14 for rotatably supporting the bearing cylindrical portion 13 on the front surface of the rotating drum 12, and a heat source 1 inside the rotating drum 12.
A sealing material 15 is attached to prevent air from entering from a point other than zero.

Furthermore, on the front surface of the rotating drum 12,
A hot air intake port 16 related to a hot air blowing port, a lifter 17 for stirring clothes on the inner surface, and a motor 21 on the rear surface supported under the outer frame 1 via a pulley 18, a tension pulley 19, and a belt 20. A pivot shaft 2 for pivoting rotation by
2. Filter case 2 to prevent thread waste generated inside the rotating drum 12 from flowing out.
3. Filter 24 is attached.

The above-mentioned motor 21 is installed at the rear of the outer frame 1.
A fan 28 is disposed whose rotation is transmitted and rotated by a pulley 25, a belt 26, and a pulley 27, and this is rotatably supported by a fan shaft 30 fixed to a beam 29 supported by the outer frame 1. .

The above fan 28 includes a fan casing 31,
The fan casing 31 is housed in a casing cover 32, and the fan casing 31 rotatably supports the shaft 22 of the rotating drum 12 through a bearing 33.

In addition, in the drum cover 9 on the front surface of the rotating drum 12, a bearing 34, a hot air passage port 35, and a hot air passage port 35 are provided above and below the outer frame 1, as shown in FIG. A rotary shielding plate 38 is rotatably disposed and has a stopper 37 corresponding to a rotation stopper pin 36 which is inserted into and supported by one of the insertion openings.

As mentioned above, what is shown in FIG. 1 is for the floor-standing mode, and the operation and effects in this case will be explained next.

Now, when the clothes are put into the rotating drum 12 and the timer 4 is set, the motor 21 is driven and the heat source 10 is turned on.

The rotary drum 12 is rotated by the motor 21, and the clothes are agitated and rotated, and the fan 28 is rotated, and the air is sucked in through the intake port 11 of the outer frame 1, passes through the heat source 10, and is aired into hot air. This removes moisture from the clothes in the rotating drum 12, and the exhaust port 7
The air is evacuated and drying is performed.

Thus, the clothes in the rotating drum 12 are rotated and agitated by the lifter 17, and the moisture in the clothes is uniformly removed, but the clothes are always lifted upward by the lifter 17 and even as they fall , which is located below the rotating drum 12 for the longest time.

This increases drying efficiency by blowing hot air intensively into the above-mentioned portions.

To this end, as shown in FIG. 3, a rotary shielding plate 38 having a hot air passage port 35 which is intended to variably restrict the hot air blowing port into the rotary drum 12 by rotation is installed inside the rotary drum 12. By disposing the warm air intake port 16 in front of the drum cover 9 and inside the drum cover 9, the hot air can flow through the rotary shielding plate 3.
Rotating drum 1 from only the hot air passage port 35 of 8.
However, the hot air passage opening 35 of the rotation shielding plate 38 is positioned below the rotating drum 12 by the rotation stop pin 36 supported by the outer frame 1. Since the air passes through the warm air passage port 35 and is blown from below the rotating drum 12, efficient drying can be achieved as described above.

Next, the above structure is rotated and placed upside down on a stand as shown in FIGS. The air is blown from above, reducing drying efficiency.

Therefore, as shown in Fig. 4, the rotation stop pin 3
6 is replaced by 180 degrees and supported by the outer frame 1, the frictional force between the bearing cylindrical portion 13 of the rotating drum 12 and the bearing 34 of the rotating shielding plate 38 causes the rotating shielding plate 38 to support the rotating drum 12. in the same direction as
It rotates in the direction of arrow A shown in FIG.

This rotation is prevented by the stopper 37
6 and is held at that point, the hot air passage port 35 of the rotating shield plate 38
Even when the drum is turned upside down as shown in Fig. 4, it is placed below the rotating drum 12, and hot air is blown out from below the rotating drum 12, allowing efficient drying. .

As described above, according to the configuration according to the above embodiment, even if the dryer main body is turned upside down depending on the installation state, it is possible to always blow hot air intensively from below the rotating drum 12. , which always allows for efficient drying.

Moreover, the position of the balloon can be changed by going to the customer's house and changing the position of the rotation stopper pin 3 depending on the installation condition.
It has the advantage and feature that it can be changed freely and easily just by changing the position of the rotation stopper pin 36, and the rotation stopper pin 36 is arranged inside the door 3 and does not protrude to the outside. There is no risk of it getting caught on it, and at the same time it does not spoil the appearance.

Although the above embodiment has a structure of a rotatable rotary shield plate having a hot air passage port, this does not have to be rotatable, and may be a rotary drum, for example. Relating to a hot air passage hole for changing the position of the hot air blowing hole into the rotating drum, which is provided near the cylindrical part of the bearing or on the drum cover without friction. The shielding plate has shutters on the top and bottom that can be opened and closed, and in the case of the embodiment shown in Fig. 1, only the lower shutter is used, and in the case of the embodiment shown in Fig. 4, the upper shutter (in this case, located on the lower side) is used. The same effect as in the previous embodiment can be expected by opening only the opening (within the opening) from the outer frame side.

Furthermore, in the above embodiment, the hot air intake port is provided on the rotating drum, but this may also be provided on the drum cover side. This is similar in that a shielding plate can be provided adjacent to the drum cover and close to the hot air intake port.

Furthermore, in the above embodiment, instead of providing a separate rotation stop pin, the screws that screw the outer frame and the drum cover are made a little longer, and if this is used as a double-use configuration, productivity will be improved. .

As described above, the present invention has a rotating drum that includes a heat source, a fan, a cylindrical bearing part, is driven by a motor, and a hot air intake port to the rotating drum, in which the cylindrical bearing part is attached to the shaft. A shielding plate having a hot air passage hole for changing the position of the hot air blowing hole into the rotating drum is arranged adjacent to the supporting drum cover and close to the hot air intake hole. Therefore, according to the present invention, it is possible to provide a clothes dryer that does not change its performance even if it is turned over depending on the installation conditions of the dryer, and has high drying performance. This invention can be said to have practical effects.
