Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dehumidifying clothes dryer with a heat exchanger 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 they are installed.

Conventionally, this type of clothes dryer has generally had a configuration as shown in FIGS. 3 and 4.

The configuration will be described below with reference to the drawings.

As shown in the figure, there is a rotary drum 2 that can freely rotate within a main body 1, a circulating air path 4 that includes this rotating drum 2 and has a heating body 3, and a cooling device for cooling the circulating air in this circulating air path 4. An air path 6, a corrugated similar exchange type fan 6, and a fan case 7 are provided, and the dynamic exchange type fan 6 blows internal circulation air and cooling air, respectively. Cooling air for cooling the circulating air is sucked in through the intake port 9 of the back plate 8 provided on the rear surface of the main body 1 and flows into the cooling vortex chamber 1.
0 and is discharged from an exhaust port 13 provided on the bottom surface.

Further, the rotary drum 2 and the heat exchange type fan 6 are rotationally driven by the power of a motor 12 provided at the upper part of the main body 1.

To explain the operation in the above configuration, when the material to be dried is put into the rotating drum 2 and the motor 12 is operated, the circulating air in the circulating air path 4 is heated by the heating element 3, the water content of the material to be dried is evaporated, and heat exchange is performed. Cooling air and circulating air are blown by the type fan 6 to condense moisture in the circulating air path 4, and the condensed water is drained from the drain port 14.

Problems to be Solved by the Invention In such conventional dehumidifying clothes dryers, cooling air is taken in only through the intake port 9 of the back plate 8, so if there is a wall behind the back plate 8, an appropriate gap is created. Even if the cooling air is secured and installed, there is a problem that cooling air cannot be effectively taken in, and the dehumidifying efficiency of the heat exchange fan 6 is reduced.

The present invention solves the above problems, and aims to provide a dehumidifying clothes dryer that can effectively suck in cooling air and improve dehumidification efficiency.

Means for Solving the Problems In order to achieve the above objects, the dehumidifying clothes dryer of the present invention includes a rotary drum that is freely rotatable in the main body, a circulating air path that includes the rotary drum and has a heating element, and a circulating air path that includes the rotating drum and has a heating element. A cooling air path for cooling the air in the air path, a corrugated heat exchange fan for blowing circulating air and cooling air, respectively, and a built-in heat exchange fan that separates the circulating air path and the cooling air path. The apparatus is configured to include a fan case and a blowing means for introducing cooling air into the cooling air path.

In the above-described configuration, cooling air is forcibly introduced into the cooling air path by the blowing means, so even if there is an obstacle such as a wall behind the back plate during installation, the cooling air can be taken in.

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.

The characteristic configuration of this embodiment is that it is provided with a blowing means for introducing cooling air into the cooling air path described in the conventional example. That is, in addition to the air inlet 9 of the back plate 8, an air blowing means 15 is provided inside the main body 1. Air blowing means 15
consists of a fan 16, an intake fan case 17, an intake wind cylinder 19, and a driving belt 18, and is installed inside the main body 1 at a corner diagonally opposite to the motor 12.

The suction side of the intake fan case 17 is connected to the wind cylinder 19, and the exhaust side is connected to the cooling vortex chamber 10 of the fan case 7. An inlet is provided on the front surface of the main body 1, and this is connected to the intake side of the wind cylinder 19. Connected.

To explain the operation in the above configuration, when the motor 12 rotates, the fan 16 is rotated via the belt 18, cooling air is taken in from the wind barrel 19, and the air discharged from the intake fan case 1a is transferred to the cooling air path 5. It is introduced into the cooling vortex chamber 1o, and pseudo-exchange is performed by the heat exchange type fan 6.

According to the dehumidifying clothes dryer of the embodiment, the cooling air is introduced into the cooling whirlpool chamber 10 by the blowing means 15, so even if there is an obstacle such as a wall behind the back plate 8, the main body Air is sucked in from the front of 1. In the above embodiment, the fan 16 is rotated via the belt 18, but a dedicated motor for the fan may be provided separately from the motor 12 and directly connected to the fan to rotate. As long as the air volume is secured, the same performance can be obtained even without the intake port on the back plate.

Effects of the Invention As is clear from the description of the embodiments above, according to the dehumidifying clothes dryer of the present invention, by providing an air blowing means for introducing cooling air into the cooling air path, a wall is formed behind the back plate. Cooling air can be effectively sucked in even if there are obstacles such as, improving dehumidification performance and shortening drying time.
