Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a clothes dryer, and particularly to a clothes dryer that can be easily switched between an exhaust type and a dehumidification type.

[Prior art]

There are two types of conventional clothes dryers: an exhaust type that exhausts humid warm air indoors, and a dehumidifying type that uses a heat exchanger to dehumidify humid warm air and does not exhaust humid warm air indoors. Since the structures of the exhaust type and dehumidifying type are significantly different, it has been impossible to combine the functions of both the exhaust type and dehumidifying type.

[Purpose of the invention]

An object of the present invention is to provide a clothes dryer that can be easily switched between an exhaust type and a dehumidification type depending on the operating environment and use.

[Summary of the invention]

The clothes dryer according to the present invention has an opening/closing door on the front of the outer frame, a rotating drum, and a blower fan inside the outer frame.

In a clothes dryer that includes a heat source and a motor that drives the rotating drum and a blower fan, and in which the inside of the outer frame is part of the air passage, the back cover includes a bearing part of the rotating drum, and an inside of the rotating drum. An exhaust port that communicates with the inside of the outer frame, an intake port that communicates with the inside of the outer frame, and a ventilation path means attachment part that communicates these exhaust ports and intake ports are provided, and a drainage port is provided on the bottom of the outer frame. This is what I did.

[Embodiments of the invention]

An embodiment of the clothes dryer according to the present invention will be described based on FIGS. 1 and 2.

Here, FIG. 1 is a longitudinal cross-sectional view of a clothes dryer according to an embodiment of the present invention with a ventilation cover locked thereto, and FIG. 2 is an exploded schematic diagram showing a reduced main part thereof oriented horizontally. FIG.

That is, 1 is an outer frame, IA is an opening/closing door, 2 is a rotating drum rotatably supported inside the outer frame 1, 3 is a semiconductor heater related to a heat source, and 4 is a heat source that passes through the semiconductor heater 3. ,
A centrifugal fan-shaped blower fan blows hot air into the rotating drum 2, 5 is a cooling fan, and 6 is a belt drive for the rotating drum 2 with a belt 7, and the blower fan 4 and the cooling fan 5 are directly connected. 8 is a motor for driving the motor 6 and the cooling fan 5 in the outer frame 1.
This is a bulkhead cover for a sump that is isolated by the interior of the sump.

Reference numeral 9 denotes a back cover, and the back cover 9 has a bearing 11 that pivotally supports the rotary drum 20 rotating shaft 10 on its recessed stepped wall 9A, and a bearing 11 that is connected to the inside of the rotary drum 2, as shown in FIG. An exhaust port 12 that communicates with the inside of the outer frame 1 and an intake port 13 that communicates with the inside of the outer frame 1 are provided, and a ventilation cover 23 relating to ventilation path means, which will be described later, indicates a ventilation path.

The exhaust port 12 is located at a position facing the ventilation port 14 around the rotation axis IO of the rotating drum 20, and between the outer circumferential portion of the vent port 14 of the rotating drum 2 and the outer circumferential portion of the exhaust port 12, Seal felt 1 fixed on the back cover 9 side
5 prevents hot air discharged from the rotating drum 2 from leaking into the outer frame 1.

Furthermore, a lint filter 16 for preventing lint from being discharged through the exhaust port 12 is removably attached to one end of the rotating shaft 10 on the front surface of the ventilation port 14 inside the rotating drum 2. It is something.

The back cover 9 and the outer frame 1 are fixed together using mounting screws 26 shown in FIG. 2, and are completely sealed by the contact surface between the back cover 9 and the outer frame 1.

A centrifugal fan-shaped ventilation fan 4 is located inside the outer frame 1 of the intake port 13 at a position facing the intake port 13, and this ventilation fan 4 causes the air taken in from the intake port 13 to The flow is heated by the semiconductor heater 3, and hot air is blown into the interior of the rotating drum 2 through the drum support 170 and the ventilation holes 18.

The outer peripheral portion of the drum support 17 supports one end of the rotating drum 2 via a self-lubricating sliding bearing 19.

In addition, air is taken in by the cooling fan 5 from the cooling air intake port 20 on the front side of the outer frame 1 to cool the coil part of the motor 6.
The cooling air is discharged to the back cover 9 through a cooling air duct 21, and 22 is a cooling air duct 21 which is designed to be exhausted to the back cover 9.
It is a drain hole provided on the bottom of the.

As above, exhaust port 12. Inlet port 13 and drain port 22
Other than that, it has a closed structure, and the inside of the outer frame 1 is thus sealed.

Reference numeral 23 denotes a ventilation cover for the ventilation path means which is detachably attached to the back cover 9 of the embodiment described above, and as shown in FIG. The ventilation cover 23 is removably attached to the fitting part 9B and the locking hole 9C by a fitting protrusion 24 and a screw 25 related to the attachment part. A ventilation path can be formed between the exhaust port 12 and the intake port 13.

Now, when the air is operated with the ventilation cover 23 shown in the figure attached, a circulation air path is formed through the blower fan 4 that circulates from the semiconductor heater 3 through the inside of the rotating drum 2 and from the exhaust port 12 to the intake port 13. The material to be dried is dried inside the rotating drum 2, and the circulating air containing moisture condenses on the inner wall of the outer frame 1 due to the temperature difference between the inside and outside of the outer frame 1, and is dehumidified by the circulating air.

The water droplets condensed on the inner wall of the outer frame 1 are removed from the outer frame 1.
Water is drained outside the machine through a drain port 22 on the bottom of the machine.

In this case, by discharging the cooling air from the cooling fan 5 to the back cover 9 through the cooling air duct 21, the effect of cooling the ventilation cover 23 whose temperature has become high due to the circulating air can be achieved as desired. It is possible.

That is, as described above, the device can be used as a dehumidifying type device, and on the other hand, if the ventilation cover 23 is removed and the device is operated, it can be used as a normal exhaust type device. .

As described above, according to the present embodiment, the insertion portion 9B of the back N9, the locking hole 9C+/therefore, the ventilation cover forms a ventilation path between the exhaust port 12 and the intake port 13. 23 can be installed and removed, which makes it easy to use the dehumidifying type and the exhaust type, which is a feature of the dehumidifying type; it does not make the room in which it is installed damp, and is also a feature of the exhaust type. , the temperature inside the rotating drum does not rise, and the material to be dried is less likely to shrink.

In addition, what used to be produced as two models, a dehumidifying type and an exhaust type, can now be equipped with both dehumidifying and exhaust functions, so production of two models can now be reduced to producing one model. This makes it possible to improve productivity and streamline production.

Therefore, the ventilation cover 2 related to the ventilation path means of the above embodiment
3 can be made into a duct-like shape, and a corresponding attachment part can be provided on the back cover.

In addition, in the above embodiment, the ventilation cover 2 is provided on the back cover 9.
Insert part 9B and locking hole 9C related to the attachment part, which attaches item 3.
However, the stepped wall 9A may be used as an attachment part, and the ventilation cover may be simply fitted and locked; in this case, the This has the advantage that handling operations become easier.

Furthermore, it is not necessary to use the above-mentioned recessed step wall or dish-shaped structure, but it is not prohibited to configure the camera back so that there is a ventilation gap between the back cover and the ventilation cover.

〔Effect of the invention〕

□ According to the present invention, a clothes dryer that can be easily switched between an exhaust type and a dehumidifying type can be obtained, and it can be said that the invention has excellent practical effects.
