Abstract

PURPOSE:To make it possible to capture the dust in a circulation route of the clothing drying machine which circulates and supplies the air heated by a heater into a drum by providing the air circulation route with a water reservoir part for storing the water generated by dehumidification and blowing the water of this water reservoir part to a mist form. CONSTITUTION:A hot air inlet 14 formed in the lower part of an annular drum supporting panel 6 provided to face a clothing inlet and outlet port 4 and a vent port 8 of a partition plate 7 disposed in the rear part of a machine frame 1 communicate and are connected by the circulation route 13. The circulation route 13 consists of an L-shaped duct 15 fixed to the drum supporting panel 6 and a cylindrical circulation casing 16 mounted to the rear surface of the partition plate 7. This duct 15 is provided with the heater 17 and is provided with a double side fan 24 of a heat exchange type across the circulation casing 16. The water reservoir part 40 is provided at the bottom end of a circulation pipe 19 integral with the circulation casing 16 in such a case. The condensed water stored therein is blown up to the mist form by a water wheel 39 rotated at a high speed to stick and drop the dust in the air into the mist water, which is then discharged by a drain hole 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying clothes dryer configured to dehumidify high-temperature and high-humidity air from the inside of a drum, heat it by a heater, and send it into the drum again.

[0002]

2. Description of the Related Art This type of dehumidifying clothes dryer is disclosed in Japanese Patent Application Laid-Open No. 2-257997, in which a water content of water condensed by a heat exchanger is provided in an air circulation path. It collects the dust in the air and passes it there to remove dust from the circulating wind.

[0003]

However, since the partition plate from the upper part is inserted into the water reservoir in order to pass the circulating air through the water in the water reservoir, the circulation path is formed by the partition plate. There is a problem that the air passage resistance increases due to the cutoff, which reduces the amount of circulating air into the drum and deteriorates the drying time and efficiency.

The present invention has been made in view of the above circumstances, and an object thereof is to enable removal of dust without reducing the amount of circulating air.

[0005]

According to the present invention, in a dehumidifying clothes dryer configured to dehumidify hot and humid air from the inside of a drum, heat it by a heater and send it into the drum again. A water reservoir for accumulating water generated by the dehumidification is provided in the circulation path, and a blowing device for blowing up the water in the water reservoir is provided.

[0006]

According to the present invention, the water accumulated in the water reservoir is blown up in the form of mist by the blow-up device, and the dust contained in the circulating wind passing therethrough falls due to the attachment of the mist and is removed.

As the blowing device, there are used a water turbine for directly blowing water in the water reservoir, a fan for blowing strong water to the water surface to blow water, and the like.
