Description

Detailed Description of the Invention The present invention introduces hot air from a heat generating source into a rotating drum, and sends the high-temperature and humid air generated in the rotating drum to a heat exchanger to dehumidify the material to be dried. The present invention relates to a dehumidifying clothes dryer, and more specifically, to an improvement in a cooling air path through which cooling air for cooling the heat exchanger passes.

In conventional dehumidifying clothes dryers of this kind, surrounding air is sent into the heat exchanger side using a blower fan to cool the heat exchanger, but the intake and exhaust ports for the cooling air are Since it was installed on the top or bottom of the dryer body, the air used for cooling the heat exchanger naturally
Air intake and exhaust must be carried out on the top or bottom of the main body, and when the main body is installed, a space for the air intake and exhaust must be provided on the top or bottom of the main body in addition to the main body space. Therefore, an installation space larger than the external dimensions of the main body is required, and the current situation is that this type of clothes dryer has installation restrictions. In recent years, there has been a need to consider space saving when installing electrical appliances indoors due to the domestic housing situation.

In addition, in a laundry type clothes dryer that performs air intake and exhaust air on the lower surface of the main body, it is necessary to take measures such as providing an opening hole in the shelf of the unit stand on which it is placed.

The present invention solves the above-mentioned conventional problems, and embodiments thereof will be described below with reference to all the accompanying drawings.

In the figure, 1 is the main body of the dryer, 2 is a rotary drum that is rotatably supported within the main body 1, 3 is a heater that is a heat source installed in the circulating air path, and 4 is heated by the heater 3. A circulation fan that guides hot air into the rotating drum 2.
Due to the rotation of the circulation fan 4, the high-temperature and humid air that has passed through the rotating drum 2 passes through the ventilation duct 6, and further,
It is sent into the dew condensation vibrator e of the heat exchanger 8 which is composed of the dew condensation vibro and the plate fins 7. The air that has passed through the dew condensation vibro is reheated by the heater 3 through the drainage duct 9 and sucked into the rotating drum 2 again.

As mentioned above, the dry air circulation path is mainly formed by the rotary drum 2, the air duct 5, the dew condensation vibro of the heat exchanger 8, and the drainage duct 9, and sealing members etc. By keeping it airtight, the circulating air flows in the direction of arrow a without leaking to the outside.

10 is a drive motor that rotates the rotating drum 2 and the circulation fan 4 via bell) 11.12' (i7, and at the same time,
Cooling fan 13 provided on the coaxial core of the drive motor 1o
Rotate. The cooling fan 13 is composed of a centrifugal fan, and the air suction side is directed toward the front of the main body 1.
The air intake port 14 provided on the front surface of the air inlet 14 is connected to the air intake side through an air intake cylinder 16 that is integrated with a fan casing 16 that accommodates a cooling fan 13. Fan casing 1
A heat exchanger 8 is installed on the outlet side of the heat exchanger 5, and the air passing between the plate fins 7 of the heat exchanger 8 is configured to be discharged to the front of the main body 1 through an exhaust air cylinder 17. .

Specifically, an exhaust port 18 is provided on the front surface of the main body 1- in which the intake port 14 is formed, and an exhaust air cylinder 16 is connected to this.

Reference numeral 19 indicates an intake filter detachably attached to the intake port 14, and arrows indicate the flow of cooling air.

20 is a drain port provided at the bottom of the drain duct 9, and 21 is a drain port for discharging dehumidified water droplets to the outside of the machine.

In the above configuration, by rotating the drive motor 1o and energizing the heater 3, the rotation of the circulation fan 4 causes the air heated by the heater 3 to enter the rotating drum 2 as shown by the arrow, and the air generated here The hot and humid air passes through the dew condensation vibro of the heat exchanger 8.

On the other hand, due to the rotation of the cooling fan 13, outside air is transferred to the air intake port 14 on the front surface of the main body 1, as shown by the arrow. Intake wind cylinder 16. It reaches the heat exchanger 8 via the fan casing 16, and is further discharged via the exhaust air cylinder 17 to the exhaust port 18 on the front surface of the main body 1.

As a result, the heat exchanger 8 is cooled as a whole, and the high-temperature and humid air in the dew condensing vibrator e is cooled, and water droplets form on the inner wall of the dew condensing vibrator to form dew condensation. These water droplets are pushed out from within the dew condensation vibro by wind pressure and gravitational force in the direction in which the circulating air passes, and are discharged to the outside of the machine through a drain port 20 provided in the drain duct 9.

Here, the air suction side of the cooling fan 13 for cooling the heat exchanger 8 is connected to the intake port provided on the front surface of the main body 1 through the intake air cylinder 16, and the Since the exhaust port 18 is provided to discharge the air after being subjected to the cooling action to the outside of the main body 1 through the exhaust air cylinder 16, the cooling air is taken in and exhausted from the front of the main body 1, as shown in FIG. The flow form of the air flows like this.

Specifically, as shown in FIG. 6, by sucking and exhausting the cooling air at the front of the main body 1, it is possible to install the cooling air in a space-saving manner, and even in close contact with the main body 1, thereby saving space.

Figure 6 shows the intake and exhaust configuration of a conventional clothes dryer.
When exhaust is performed on the top surface of the main body, the gap X' between the ceiling and the ceiling becomes extremely large due to the necessity of an intake and exhaust passage, as shown in Figure (A). In this case, it is also necessary to ensure a gap y' on the side surface of the main body 1, which requires a very large space for installation, which imposes restrictions on installation.

However, as is clear from the above embodiments, according to the present invention, the installation space of the dehumidifying dryer can be kept to a minimum, making it possible to respond to residential situations with space saving, and without having any adverse effect on the drying and dehumidifying performance. It is possible to obtain the installation state without giving.
