Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention directs hot air from a heat generating source into a rotating drum and has a high In? This invention relates to a dehumidifying clothes dryer that sends humid air into a heat exchanger, dehumidifies it, and dries objects to be dried.

Conventional structure and its problems Conventionally, in this type of dehumidifying clothes dryer, the intake and exhaust ports of the air path for cooling the heat exchanger are arranged on the bottom of the main body, and the space under the main body is A system was adopted in which cold air was sucked in from the tank and the air used for heat exchange was exhausted downward.

However, in this structure, since the heat exchanger is provided in the lower space of the main body, the center of the drum corresponding to the clothes input port is located at a relatively high position, and as a result, the height of the clothes input port is increased. It was expensive and inconvenient to use.

In addition, when the outside temperature is low, dew condensation occurs on the inner walls of the main body. Conventionally, this was removed by providing holes in the main body for cold air intake or by equipping the main body with a motor cooling fan. The cooling air path was not sufficiently sealed, reducing heat exchange performance and making the assembly of the structure 9 complicated.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks and aims to improve usability in response to the increasing demand for dryers to be installed using space on the machine. This prevents dew condensation on the inner walls of the main body at low temperatures.

Structure of the Invention In order to achieve the above objects, the dehumidifying clothes dryer of the present invention rotatably supports a rotating drum in the main body of the device, and the main body is provided with a clothes inlet to allow hot air from a heat source to flow through the dryer. A dehumidifying clothes dryer in which high-temperature and humid air from the rotating drum is guided into the drum and sent into a heat exchanger, and the heat exchanger is disposed in the upper part of the device body to cool the heat exchanger. The intake port for the air path of the tank is provided on the top surface of the device body, and the exhaust port is provided on the bottom surface of the device body, and the device body other than the intake port and the exhaust port is of a nearly sealed structure, and the heat exchanger is cooled. The air path is formed using the space inside the main body.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is the main body of the dryer, 2 is a rotating drum rotatably supported within the main body 1, 3 is a heater provided in the middle of the circulating air passage, and 4 is the hot air heated by the heater 3, which is transferred into the rotating drum 2. The high-temperature and humid air that has passed through the rotating drum 2 through the circulating fan passes through the ventilation duct 5,
Furthermore, it is sent into the dew condensation vibro 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 of the heat exchanger 8 passes through the drainage duct 9, is reheated by the heater 3, and is re-inhaled into the rotating drum 2.

As mentioned above, the dry air circulation path is connected to the rotating drum 2.
．． Circulation fan 4. Air duct 5. Heat exchanger8. Drainage duct9. It is formed by the vicinity of the heater 3, and by keeping these members airtight with each other using a sealing member or the like, the circulating air flows in the direction of arrow a.

1o is a cooling fan installed inside the main body 1, and this fan 1o
The cooling air passes between the plate fins 7 of the heat exchanger 8 and cools the hot and humid air passing through the dew condensing tube 6. Therefore, water droplets are formed on the inner wall of the dew condensing vibro. This water is pushed out of the dew condensation vibro of the heat exchanger 8 by wind pressure and gravity in the direction in which the circulating air passes, and is discharged to the outside of the machine from a drain pipe 11 provided in the discharge duct 9.

Reference numeral 12 denotes a drive motor that rotates the rotating drum 2 and the circulation fan 4 via belts 13 and 14, and simultaneously drives the circulation fan 4. A cooling fan 1o is rotationally driven via a belt 15.

Here, the heat exchanger 8 is disposed in the upper part of the main body 1, and an air intake port 1 for cooling the heat exchanger is provided.
6 is provided on the top surface of the main body 1, and the air that has cooled the heat exchanger 8 is pushed out of the main body 1 through an exhaust port 17 provided on the bottom surface of the main body 1.

The main body 1 other than the intake port 16 and the exhaust port 17 has a substantially sealed configuration, and the air heat exchanged by the cooling fan 10 is sent to the exhaust port 17 using the space inside the main body 1 as a cooling air path. , will be pushed out from here. The air flow at this time is indicated by arrows.

According to the above configuration, the heat exchanger 8 and the cooling fan 10 are disposed in the upper part of the main body 1, and the air intake port 16 is arranged in the upper part of the main body 1.
By providing it on the top surface, as shown in Fig. 2, the height X of the clothes input port 1a is smaller than y, and the height of the clothes input port 12L is lower than before, making it easier to put in and take out clothes. The ease of use is significantly improved.

Still, the exhaust port 17 is formed on the bottom surface of the main body 1, and the heat exchanger 8
By forming a cooling air path using the space inside the main body 1, humid air leaking due to deterioration of the airtight seal in the circulating air path can be forcibly exhausted, and the cooling air path can be forcibly exhausted from the main body 1 when the outside temperature is low. Prevents condensation from forming on the inner walls.

By improving the position of the air intake and exhaust ports of the air path for cooling this heat exchanger,
If the height of the clothes slot corresponding to the rotating drum can be lowered than before, such as when setting it above the washing machine,
Clothes can be put in and taken out easily, and dew condensation does not occur on the inner walls of the main body, eliminating problems such as deterioration of insulation performance of electrical parts and falling water droplets.
