Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dehumidifying clothes dryer that has a dehumidifying function using a heat exchanger and dries clothes.

Conventional configurations and their problems Conventionally, in general dehumidifying clothes dryers, in order to increase the efficiency of heat exchange, the size of the heat exchanger was almost the same as the size (width) of the main unit. It is. On the other hand, due to the size and space of the cooling fan, the location of the cooling fan may not necessarily correspond to the center of the heat exchanger.
In particular, if the cooling fan a and the circulation fan b are arranged side by side on the same axis as shown in FIG. 1, taking compactness into consideration, the cooling fan a will lean from either the left or the right with respect to the heat exchanger c. When air is blown in this state, the flow of cooling air mostly hits the fins on one side of heat exchanger c, as shown by arrow d, and not much cooling air flows to the fins on the opposite side of cooling fan a, resulting in heat exchange. The problem was that the efficiency of the equipment was poor. In FIG. 1, the same reference numerals as in FIGS. 2 and 3, which will be described later, indicate the same members.

Purpose of the Invention It is an object of the present invention to provide a dehumidifying clothes dryer that solves these conventional problems, improves the efficiency of the heat exchanger, and makes the clothes dryer more compact. .

Structure of the Invention In order to achieve the above object, the present invention includes a cooling fan that blows air to cool a heat exchanger, and a wind barrel that configures a cooling air path for the heat exchanger, and the wind barrel is connected to the cooling fan. A cooling air outlet is also provided on the side of the heat exchanger on the far side, making it easier for the cooling air to flow not only toward the cooling fan side but also in the direction of the outlet, so that the cooling air hits the entire heat exchanger. This improves the efficiency of the heat exchanger.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 and 3, reference numeral 1 denotes a rotating drum for storing clothing, which is rotationally driven by a motor 2 via a belt 3. 4 is a heater for heating the circulating air entering the rotating drum 1; 5 is a heat exchanger; 6
is a circulation fan that blows circulating air, and the air intake cylinder 7
The air inside the rotating drum 1 is sucked in through the rotary drum 1 and blown to the heat exchanger 5. 8 is a cooling fan for blowing cooling air to the heat exchanger 5, and the air intake hole 9 is inserted from the outside.
Air is sucked in through the heat exchanger 5 and sent to the heat exchanger 5.

Reference numeral 10 denotes a wind cylinder for sending cooling air to the heat exchanger 5, and is configured to cover the outside of the heat exchanger 5. Cooling air inlet 10
a, an outlet 10b is formed, and an outlet 10c is also provided in a portion of the wind barrel 10 on the side surface of the heat exchanger 5 opposite to the cooling fan 8.

The circulation fan 6 and the cooling fan 8 are located on the same shaft 11, and are connected to the motor 2 via a pulley 12 and a belt 13.
It rotates by receiving the rotational force of.

Reference numeral 14 denotes an outer shell of the dryer, and an exhaust port 15 for cooling air is provided on the lower surface of the outer shell. 16 is a drainage hose for discharging water condensed by the heat exchanger 5. Further, in the figure, black arrows indicate circulating (dry) air paths, and white arrows indicate cooling air paths.

The operation in the above configuration will be explained. When the operation starts, the hot and humid air in the rotating drum 1 is sucked in by the circulation fan 6 through the intake air cylinder 7 and sent to the heat exchanger 5. So cooling fan 8
The hot and humid air is cooled by the low-temperature air sent in, dew condensation occurs within the heat exchanger 5, and the water is discharged to the outside through the drain hose 16. Further, the air exiting the heat exchanger 5 is heated by the heater 4 and enters the rotating drum 1 as high-temperature dry air. At this time, the more dew water is in the heat exchanger 5, the faster the clothes in the rotating drum 1 will dry.
Dryer performance improves.

Here, in order to increase the amount of dew water, heat exchanger 5
It is necessary to apply cooling air to the entire cooling fin.

With the configuration of this embodiment, the cooling air flows through the outlet 10.
It also becomes easier to flow toward c, allowing the cooling air to pass through the entire heat exchanger 5, increasing the heat exchange efficiency of the heat exchanger 5, increasing dew condensation, and improving drying performance. be.

Furthermore, as shown at 17 in FIG.
It becomes easier to flow in this direction, and the heat exchange efficiency mentioned above is further increased.

Effects of the Invention As is clear from the above embodiments, according to the present invention,
Even if the cooling air blowing position of the cooling fan is not in the center of the heat exchanger, the cooling air is distributed throughout the fins of the heat exchanger, improving heat exchange efficiency and the drying performance of the dryer. I can,
Moreover, since the arrangement position of the cooling fan can be changed relatively freely in terms of design, a compact clothes dryer can be provided depending on the arrangement position.
