Description

DETAILED DESCRIPTION OF THE INVENTION The present invention guides hot air from a heat source into a rotating drum, sends the high-temperature and humid air generated in the rotating drum into a heat exchanger to dehumidify it, and dehumidifies the material to be dried. The present invention relates to a dehumidifying clothes dryer for drying, and more specifically, to an improvement in a cooling path through which cooling air for cooling the heat exchanger passes.

This type of conventional dehumidifying clothes dryer is equipped with a circulating air path that sends high-temperature and humid air generated in a rotating drum to a heat exchanger and circulates it through a heated air cylinder that has a heating element inside. However, the airtightness of the sliding parts and connecting parts of the functional parts that make up the circulating air path is currently not perfect due to deterioration of the seals, variations in the dimensions of the functional parts, etc.

In order to achieve perfect airtightness, it is necessary to make major structural improvements to sliding parts and connecting parts, use special materials, eliminate variations in functional parts, etc., which would make the product extremely expensive. However, it is accompanied by many difficulties.

On the other hand, even if there is a small gap, the product's function is fully fulfilled, and as mentioned above, the airtightness is not perfect at present. A complete wall here means 100% airtight.

Therefore, under such a circulating air path, during operation, a small amount of circulating air may leak into the interior space of the aircraft, causing hot and humid air to condense on the interior walls of the aircraft, reducing the quality of electrical components, and increasing the temperature of the aircraft. This had negative effects such as increasing the

The present invention solves the above-mentioned conventional problems by connecting the air intake opening of the cooling blower provided in the main body to cool the heat exchanger and the outside air intake port provided in the main body to reduce the space inside the main body. By communicating through the heat exchanger and discharging the air blown to the heat exchanger to the outside of the main unit, the small amount of hot and humid air leaking into the main unit is immediately exhausted to the outside of the machine, preventing dew condensation inside the main unit.
This is intended to prevent the temperature of the aircraft from rising.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the main body of the dryer, 2 is a rotary drum rotatably supported in the main body 1, 3 is a heater which is a heating element installed in the middle of the circulating air path, and 4 is heated by the heater 3. This is a circulation fan that guides the heated 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 air duct 6, and is further removed from the dew condensation vibro and the plate fins 7. heat exchanger 8
is sent into the dew condensation vibe θ. The air that has passed through the condensation pipe 6 passes through the drainage duct 9, is reheated by the heater 3, and is sucked into the rotating drum 2 again.

As mentioned above, the circulating air path for dry air is mainly formed by the inside of the rotating drum 2, the air duct 6, the dew condensation vibro of the heat exchanger 8, and the drainage duct 9, and sealing members etc. By keeping it airtight, the dry air flows in the direction of arrow a without leaking to the outside.

1o is a drive motor, which connects the rotating drum 2 and circulation fan 4.
is rotated via bells) 11 and 12. A cooling fan 13 is provided on the coaxial core of the drive motor 1o, that is, at the end of the rotating shaft 1oa. This cooling fan 13 and the fan casing 14 constitute a cooling device. The cooling fan 13 is composed of a centrifugal fan or the like, and the air suction opening 14a provided in the fan casing 14 opens into the main body 1, and the fan casing 1
4, the air blown by the cooling fan 130 rotations is guided to the plate fins 7 of the heat exchanger 8 by the knee 6. 16 is a cover surrounding the heat exchanger 8;
One end side communicates with the air discharge side of the fan casing 14: 1=-9, and the other end of the cover 15 communicates with the outside of the machine via an exhaust port 16 formed on the bottom surface of the main body 1.

A 17-piece outside air intake port 17 is formed in the main body 1, and a removable intake filter 18 is attached to the outside air intake port 17. The air intake opening 14a and the outside air intake port 17 communicate with each other via the space within the main body 1, thereby forming an intake path. That is, the rotation of the cooling fan 13 reduces the pressure of the air inside the main body 1, and the outside air is taken in from the outside air intake port 17. Arrow a indicates the flow of drying air, and arrow s indicates the flow of cooling air.

Moreover, 19 is a drainage port provided at the bottom of the drainage duct 9.

In the above configuration, by rotating the drive motor 10 and energizing the heater 3, the rotation of the circulation fan 4 causes dry air heated by the heater 3 to enter the rotating drum 2 as shown by the arrow a. The high-temperature and humid air generated here passes through the dew-condensing vibro of the heat exchanger 8.

On the other hand, as the cooling fan 130 rotates, as shown by the arrow, the outside air of the main body 1 is transferred through the air intake opening 14a of the fan casing 14 covering the intake port 17, the cooling fan 13, and the fan casing 14. cover 15
The outside air guided inside the plate fins 7 of the heat exchanger 8
pass between.

As a result, the heat exchanger 8 is cooled as a whole, the hot and humid air inside the dew condensing vibro is cooled, and water droplets are condensed on the inner wall of the dew condensing vibro. These water droplets are pushed out from inside the dew condensation vibro by wind pressure and gravity in the direction in which the circulating air passes, and are discharged to the outside of the machine through a drain port 19 provided in the drain duct 9.

The cooling air subjected to the heat exchange action exits from the cover 16 and is discharged to the outside of the machine through an exhaust port 16 provided on the lower surface of the main body 1.

As described above, the intake path of the cooling fan 13 is
Since the air intake opening 14a and the outside air intake port 17 are configured to communicate with each other through the internal space of the main body 1, the cooling fan 13
Due to the zero rotation, the air inside the main body 1 is depressurized, and outside air is taken in through the outside air intake port 17. At this time, air intake opening 1
A small amount of dry air, that is, high-temperature and humid air leaking into the main body 1 from a small gap in the circulating air path is also taken in from 4a and discharged to the outside of the machine.

Further, since an air intake path can be formed by communicating the outside air intake port 17 and the air intake opening 14a through the space inside the main body 1, the outside air intake port 17 can be formed at any position on the wall surface of the main body 1. In addition, the air intake opening 14a may be placed at any position within the main body 1, allowing flexibility in design, for example, allowing the product to be made into a interconnect. This allows for an advantageous design.

As described above, according to the present invention, in particular, in the cooling structure of a heat exchanger for dehumidification, the air intake opening of the cooling blower and the outside air intake port provided in the main body are connected through the space inside the main body. By operating the above-mentioned air blower, the air inside the main body is depressurized and an intake path is formed through which outside air is taken in from the outside air intake port, so that a trace amount of dry air (
It is possible to quickly exhaust hot and humid air outside the aircraft, prevent condensation on the internal walls of the main body, and reduce the rise in temperature of the aircraft.In addition, the connection duct between the air intake opening of the cooling blower and the outside air intake port, etc. This eliminates the need for other parts, simplifying the structure and streamlining assembly. Furthermore, the outside air intake port, which is the intake port for cooling air, can be placed anywhere on the wall of the main body, and the air intake opening can be placed anywhere inside the main body. This has great effects, such as streamlining the design.
