BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer, and more particularly to a clothes dryer that does not use a heater.
In particular, the present invention provides a dryer suitable for drying small items such as underwear indoors.

[0002]

2. Description of the Related Art Conventionally, clothes are dried by forcedly blowing heated air into a rotary drum or a casing. In this case, since a heater is required to obtain heated air, there is a problem that the space for housing the heater is increased in size. Therefore, in recent years, a ventilation type clothes dryer has been proposed in which room air is circulated and supplied to the casing to dry clothes with low-temperature air (actual Kaihei 2-112).
297).

In Japanese Utility Model Application Laid-Open No. 2-112297, an air inlet is opened at the top of the casing, an air outlet is opened at the bottom of the casing, and a fan chamber and a clothes storage chamber to be dried are provided inside the casing. By activating the fan housed in the fan chamber, the room air taken in from the air intake is blown toward the clothes to be dried.

[0004]

In the conventional ventilation type clothes dryer, the clothes are dried by circulating the indoor air, that is, the low temperature air, so that the heating device such as a heater can be omitted to make it compact. Although there is an advantage that it can be done and it is easy to handle, in this conventional ventilation type clothes dryer, the air flow is blown from the blower toward the clothes to be dried, so the wind flow is not dried. The flow follows the surface of the clothing. At this time, since the wind flows in a laminar flow, there is no movement of air on the surface of the clothes to be dried, and evaporation of water contained in the clothes cannot be expected.
As a result, there is a problem in that the processing time until the clothes to be dried are completely dried becomes long.

Further, the conventional ventilation type clothes dryer has a problem that it is a stationary type and always requires a large installation space. The present invention has been made paying attention to such a point, and while adopting a ventilation drying method using low temperature air,
An object of the present invention is to provide a small-sized ventilation type clothes dryer that can be completely dried in a short time.

[0006]

In order to achieve the above-mentioned object, according to the present invention, a lid plate is pivotably supported on a casing having an open upper surface so that the lid plate can swing upward and downward, and the upper opening is formed by the lid plate. It is configured so that it can be opened and closed, and a blower fan and an electric motor that drives this fan are arranged at the bottom of the casing, and the discharge port of the blower fan is arranged so as to face the discharge port formed at the lower side wall of the casing. The clothes placing table formed in a folding screen shape with a plate made of a ventilation material is placed in the upper opening so that the ridge line portion is horizontal, and the clothes placing table is extended to cover the opening. It is characterized in that it can be switched to a storage posture in which it is stored in the casing sideways in this state.

[0007]

In the present invention, the cover plate is pivotably supported on the casing having an open upper surface so that the upper opening can be opened and closed by the cover plate, and the blower fan and the blower are installed at the bottom of the casing. An electric motor that drives the fan is arranged, and the discharge port of the blower fan is arranged so as to face the exhaust port formed in the lower part of the side wall of the casing. The garment placing table is placed with its ridge lined sideways, and it can be switched between a use position where the garment placing table is expanded to cover the opening and a storage position where the garment placing table is stored horizontally in the casing when folded. Therefore, when the clothes placing table is expanded to the opening of the casing and the blower fan is operated, the inside of the casing is in a negative pressure state and suction air is formed to penetrate the clothes placing table. ,clothing Suction air will act on the dry clothes placed on the table. Therefore, when the clothes to be dried are placed on the placing table, the treated air flows in a state of penetrating the clothes and removes the water present inside the clothes, so that the clothes can be strongly dried in a short time.
