Abstract

PURPOSE:To expedite a dehumidification function by the turbulent flow of circulation air and to improve dehumidification performance by providing a projecting part intersecting orthogonally to the flowing direction of the air at the inner wall of a duct comprising part of a drying air route including a rotary drum and provided with a heater. CONSTITUTION:When a material to be dried is thrown in the rotary drum 2 and a motor is rotated, the circulation air on the drying air route 4 is heated by the heater 3, and a water component in the material to be dried is evaporated, and humidity is condensed by a heat exchange type fan 6, and the circulation air flows in the duct 12. The humidity is eliminated from the air, but, since still high temperature and high humidity exist, the air is cooled by a stream of the air in a main body 1, and dew consensation occurs on the inner wall of the duct 12. The duct 12 is molded in thin thickness, and the projecting part 13 is provided at the inner wall so as to intersect orthogonally to the flowing direction of the circulation air, therefore, the circulation air generates the turbulent flow in the duct 12, and humidified air is always switched on the wall plane of the duct 12, which expedites the dehumidification function.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a clothes dryer equipped with a heat exchange fan.

BACKGROUND OF THE INVENTION In recent years, clothes dryers have been widely used to streamline daily life, and dehumidifying types equipped with heat exchangers have become mainstream in order to improve the indoor environment in which clothes dryers are installed.

Conventionally, this type of clothes dryer has generally had a configuration as shown in Japanese Patent Publication No. 60-56618.

The configuration will be explained below with reference to FIG.

As shown in the figure, the clothes dryer includes a main body 1, a rotary drum 2 rotatably provided in the main body 1, a dry air path 4 including the rotary drum 2 and a heating body 3, and a dry air path 4 including the rotary drum 2 and a heating body 3. a cooling air path 5 for cooling the circulating air in 4;
A heat exchange type fan 6 for blowing circulating air and cooling air into the dry air path 4 and cooling air path 5, respectively, and a fan holder 77 containing the heat exchange type fan 6 are provided.

The dry air path 4 is provided with an abbreviated-shaped duct 8 made of a synthetic resin material or the like on the downstream side of the heat exchange type fan 6,
This duct 8 is connected to a case 79 of the heating body 3. The rotary drum 2 and the heat exchange type fan 6 are driven to rotate by the power of a motor 10 provided on the upper surface of the main body 1.

In the above configuration, the dehumidifying effect is originally performed by the heat exchange fan 6.
However, the duct 8 is made of a thin synthetic resin material, and the circulating air flowing through the duct 8 has high humidity, so the duct 8 is cooled by the air inside the main body 1. Although it is a slight amount, dew condenses on the inner wall of the duct 8 and a dehumidifying effect is achieved. Then, when the material to be dried is put into the rotating drum 2 and the motor 1o is operated, the circulating air in the drying air path 4 is heated by the heating element 3 and the water content of the material to be dried is evaporated. The moisture is condensed, and the condensed water is drained from the drain port 11 via the duct 8.

Problems to be Solved by the Invention In such conventional clothes dryers, improvements such as heat exchange fans have been made to improve dehumidification performance, but there are limitations, and it is necessary to dehumidify inside the duct 8 to improve performance. Nothing had been done.

The present invention solves the above problems, and aims to provide a clothes dryer that can promote dehumidification in the duct and improve dehumidification performance.

Means for Solving the Problems In order to achieve the above object, the present invention has a structure in which the inner wall of the i4 duct of the clothes dryer of the present invention is provided with a convex portion perpendicular to the flow direction of the circulating air.

Effect: In the above configuration, turbulent flow of circulating air occurs within the duct, and this turbulent flow promotes the dehumidification effect.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. In this embodiment, the same components as those shown in the above-mentioned conventional example are given the same reference numerals, and the explanation thereof will be omitted.

A characteristic feature of this embodiment is that a convex portion is provided on the inner wall of the duct. That is, the heat exchange type fan 6 of the dry air path 4
A duct 12 is provided on the downstream side of the heating element 3, and this duct 12 is connected to the case 79 of the heating element 3. The duct 12 has an abbreviated shape, is thinly molded from a synthetic resin material, and has several protrusions 13 on its inner wall so as to be orthogonal to the flow direction of the circulating air.

To explain the operation in the above configuration, when the material to be dried is put into the rotating drum 2 and the 7-10 is operated, the circulating air in the drying air path 4 is heated by the heating element 3, and the water content of the material to be dried is evaporated. The heat exchanger fan 6 condenses the moisture and forces the circulating air into the duct 12. Although this air has been dehumidified, it is still hot and humid, so it is cooled by the air flow inside the main body 1 and condenses on the inner wall of the duct 12. The duct 12 is formed thin and has a convex portion 13 on its inner wall so as to be orthogonal to the flow direction of the circulating air, so the convex portion 13 causes turbulence in the circulating air within the duct 12, causing it to become damp. In addition, the ducts are constantly replaced on the wall of the duct 12 to promote the dehumidification effect.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, by providing the inner wall of the duct with a convex portion that intersects IM in the flow direction of the circulating air, the dehumidification effect due to the turbulent flow of the circulating air can be improved. dehumidification performance can be improved.
