[Industrial applications]

 The present invention relates to a clothes dryer, and more particularly to a clothes dryer that does not use a heater.

[0002]

[Prior art]

 Conventionally, clothes are dried by forcedly blowing heated air into the rotary drum or casing. In this case, since a heater is required to obtain the heated air, there is a problem that the space for accommodating 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 (Japanese Utility Model Publication No. 2-112297).

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 the fan chamber and the clothes to be dried are placed inside the casing. A room is formed, and the room air taken in from the air intake is blown toward the clothes to be dried by activating the fan housed in the fan room.

[0004]

[Problems to be solved by the device]

 In the conventional ventilation type clothes dryer, clothes are dried by circulating indoor air, that is, low-temperature air. Therefore, the heating device such as a heater can be omitted and the structure can be made compact and the handling is simple. However, in this conventional ventilation type clothes dryer, since the blower blows the compressed air toward the clothes to be dried, the air flow is along the surface of the clothes to be dried. 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 it cannot be expected that water contained in the clothes evaporates. As a result, there is a problem in that it takes a long time to completely dry the clothes to be dried. The present invention has been made paying attention to such a point, and an object thereof is to provide a ventilation type clothes dryer which can completely dry in a short time while adopting a ventilation drying method using low temperature air. .

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention forms a drying unit and a fan accommodating part up and down inside a casing having an outside air intake opening at the top, and a fan and a fan driving part in the fan accommodating part. A motor is arranged so that the outside air taken into the casing from the outside air inlet passes through the drying section and reaches the fan accommodating section, with the outlet of the blower fan facing the exhaust outlet opening at the bottom of the casing. The feature is that a mountain-shaped mounting table made of a plate made of a ventilation material is arranged in the drying section in a state where a plurality of mountain-shaped portions are arranged side by side.

[0006]

[Action]

 According to the present invention, a drying section and a fan accommodating section are vertically formed inside a casing having an outside air intake opening at an upper part, and a blower fan and a fan drive motor are arranged in the fan accommodating section to remove the outside air intake. The outside air taken into the casing from the inlet passes through the drying section and reaches the fan storage section.The discharge port of the blower fan is placed so as to face the exhaust port that opens at the bottom of the casing. Since a mountain-shaped mounting table made of a plate made of a ventilation material is arranged with a plurality of mountain-shaped portions arranged side by side, when clothes to be dried are placed on the mountain-shaped mounting table, suction air is blown to the clothes to be dried. As a result, the treated air flows through the clothes to carry away the water present inside the clothes, and the air on the surface of the clothes to be dried is constantly observed. Evaporation of water from the surface of clothing Become a lively, it becomes possible to strongly dry in a short period of time.

【Example】

 The drawings show an embodiment of the present invention. FIG. 1 is a partially cutaway perspective view of a ventilation type clothes dryer, and FIG. This clothes dryer has a box-shaped casing (3) composed of a main body part (1) having an open upper surface and a lid body (2) for closing the opening part, and a drying part (4) and a fan housing. The fan (6) and the fan driving motor (7) are arranged in the fan housing, and the discharge port (8) of the blower fan (6) is formed in the main body part ( It is arranged so as to face the air outlet (9) formed in the lower part of the side wall of (1), and the outside air intake (10) is opened on the ceiling surface of the lid (2).

A communication hole (12) is opened in the center of a partition wall (11) that partitions the drying section (4) and the fan accommodating section (5). Further, a placing table (13) for clothes or the like is arranged in the drying section (4) which is the upper side of the partition wall (11). The mounting table (13) is a synthetic resin plate having open cells, and is formed in a shape in which the mountain shape is continuous in the lateral direction.

Further, a filter material (14) such as a non-woven fabric or a net is attached to the outside air intake (10) opened in the lid (2) of the casing (3), and fine dust in the room is attached. Are prevented from flowing into the casing. Although not shown in the figure, an exhaust passage is connected to the outside of the exhaust port (9) and the inside of the exhaust passage is formed into a detour so that noise such as wind noise of the blower fan can be silenced. May be.

In the clothes dryer thus formed, clothes to be dried (15) such as clothes and towels are placed on the placing table (13) in a folded state, and the blower fan (6) is operated. Due to the air suction action of the blower fan (6), a flow of suction air from top to bottom is generated in the drying section (4), and the material to be dried (15) is positioned in the air flow.

Further, since the mounting table (13) formed of the open-cell synthetic resin plate is positioned so as to partition the drying section (4), the air flow formed in the drying section (13) is not affected. The flow is formed so as to penetrate through the material to be dried (15) and the mounting table (13), and the material to be dried (15) is pressed against the mounting table (13) by wind pressure. Then, the wind penetrating the material to be dried (15) absorbs the moisture remaining inside the material to be dried (15) or takes it out to the surface. Moreover, since the mounting table (15) is formed in a mountain shape, the air flow in the drying section (4) flows along the surface on the upper side of the material to be dried and along the lower surface of the mounting table (13). Since a streamline also flows, the contact time between the wind and the material to be dried is long, and the material to be dried is dried in a short time.

FIG. 3 shows the drying time when the wind speed at the air outlet (9) is set to 0.5 m / sec and a cotton cloth, a synthetic fiber cloth, or a woolen sock is used as the material to be dried. It is a graph which shows the relationship with a dry matter moisture residual amount. In this case, the dried object was lightly squeezed by hand and spread on the mounting table (13) for the experiment. For cotton cloth and synthetic cloth, one cloth was folded in two (2 layers) and two cloths were folded in two (4 layers).

In the above embodiment, the mounting table (13) is formed of an open-cell synthetic resin plate, but may be formed of a mesh body such as a wire mesh, a sintered metal plate body, or a porous metal plate. . In this case, the mounting table (13) needs to have both air permeability and self-supporting property, and it is desirable that a fine opening is exposed at least on the upper surface on which the material to be dried is mounted. Further, an infrared irradiation lamp may be arranged below the mounting table (13) so that the clothes to be dried are bulky treated with far infrared rays or near infrared rays emitted from the infrared irradiation lamp. .
