Description

[Detailed Description of the Invention] The present invention relates to a rotating drum type clothes dryer, and the cabinet housing the rotating drum can be used in common for both exhaust type and dehumidifying type clothes dryers.

Embodiments of the present invention shown in the drawings will be described in detail below. Note that FIGS. 1 to 3 show the invented clothes dryer of the exhaust type, and FIGS. 4 to 7 show the invented clothes dryer of the dehumidifying type.

In the figure, 1 is a cabinet having a clothes input port 2 on the front, 3 is a door for opening and closing the clothes input port 2,
Reference numeral 4 denotes a rotary drum rotatably installed inside the cabinet 1, which has an opening for putting in clothes at the center of the front surface, an air intake section 5 consisting of a large number of small holes on its outer periphery, and a large number of small holes at the center of the rear surface. An air discharge section 6 consisting of a hole is formed. Reference numeral 7 denotes a front cover that covers the air intake section 5 and forms a passage between it and the front surface of the rotating drum 4, and a heater 8 is installed inside the front cover. 9 is an air intake port formed on the front surface of the cabinet 1; 10 is a fan case that is installed inside the cabinet 1 with its suction side aligned with the air intake port 9; together with the front cover 7, the fan case extends from the air intake port 9 to the air intake portion 5. Forms an intake passage. 11
is a motor installed in the cabinet 1, a fan 12 is attached to one end of the rotating shaft in the fan case 10, and the rotating drum 4 is connected to the other end via a pulley and a belt. The drum 4
Rotate. Reference numeral 13 denotes a rear cover that covers the air exhaust section 6 and forms an exhaust passage 14 between it and the rear surface of the rotary drum 4;

A heat exchanger 16 has a water receiving box 17 connected to the outlet side and together with the box 17 constitutes a heat exchange unit, and is interposed between the exhaust passage 14 and the vent 15. The above-mentioned cabinet 1 has a space necessary for incorporating a heat exchange unit and an accompanying cooling fan, etc. at the inner bottom thereof. That is,
When a heat exchange unit is installed in the cabinet 1, a cooling passage 18 is formed in the inner bottom so that both ends thereof are open to the outer bottom surface, and a heat exchanger 16 and a cooling fan (not shown) are installed in the cooling passage 18. Arrange.
In this case, the cooling fan uses the motor 11 as a driving source and rotates via transmission means such as a pulley or a belt. 19 is a drainage hose that guides the condensed water generated in the heat exchanger 16 to the outside; 20 is an exhaust passage 14;
This is an exhaust duct that is connected to the end of the cabinet 1 and exhausts the air to the rear of the cabinet 1, and is used when a heat exchange unit is not installed.

Reference numeral 21 denotes a communication cover that is attached to the front of the cabinet 1 to cover the intake port 9 and the ventilation port 15 and connect the two ports 9 and 15, and has a relatively large opening 22 on the front.
has. 23 is an intake filter disposed in the opening 22 of the communication cover 21, and 24 is also the opening 2.
2, and is used selectively with the intake filter 23. Note that the intake filter 23 and the closing plate 24 have, for example, an elastic engagement piece, and are removably disposed in the opening 22 of the communication cover 21 using this elastic engagement piece.

In the above configuration, when assembled as a dehumidifying type clothes dryer, a heat exchange unit is installed at the inner bottom of the cabinet 1, as shown in FIGS. 4 to 7.
The cooling fan and the components of the cooling passage 18 are installed, and the opening 22 of the other communication cover 21 is closed with the closing plate 2.
4 to connect the intake port 9 and the ventilation port 15. However, in this state, heater 8 and motor 1
1 and starts operation, the rotating drum 4 rotates to agitate the items to be dried such as clothes, and the cooling fan forcibly blows cooling air (outside air) into the cooling passage 18 to cool the heat exchanger. While the dry air is cooled by the fan 12, the dry air is repeatedly circulated in the following order: heating by the heater 8 → drying of the material to be dried inside the rotating drum 4 → cooling and dehumidifying in the heat exchanger 16 → It will proceed with drying of dried items, and will function as a dehumidifying type clothes dryer.

In addition, when using an exhaust type clothes dryer, the first
As shown in FIGS. 3 to 3, the exhaust duct 20 is connected to the end of the exhaust passage 14 without incorporating the heat exchange unit, the cooling fan, the components of the cooling passage 18, etc., and the opening 22 of the communication cover 21 is connected to the exhaust duct 20. An intake filter 23 is disposed at. However, when the heater 8 and the motor 11 are energized to start operation in this state, dry air is sucked in from outside the machine through the intake filter 23 and moist dry air is discharged from the exhaust duct 20 to the outside of the machine. It will act as a dryer.

In this way, the intake filter 23 and the blocking plate 24
It can be converted into a dehumidifying type and an exhaust type by replacing it with a heat exchanger, attaching and detaching a heat exchange unit, etc., and many parts such as the cabinet 1 can be shared.

The present invention is not limited to the embodiments described above and shown in the drawings, and may be modified as appropriate without departing from the scope of the invention, such as by providing the intake port 9 and the ventilation port 15 on the side or rear surface of the cabinet 1. Of course, it can also be implemented.

As described above, according to the configuration of the present invention, it is possible to switch between the dehumidifying type and the exhaust type by replacing the intake filter and the blocking plate, attaching and detaching the heat exchange unit, etc., and many parts including the cabinet are shared by both types. This is extremely useful in practice.
