Abstract

PROBLEM TO BE SOLVED: To always obtain an efficient dried condition and reduce the drying time and the electric power consumption and further the drying cost, by automatically opening/closing a shutter in accordance with the condition whether or not a drying shelf is charged in the drying chamber and opening the shutter when the drying shelf is charged. SOLUTION: When a drying shelf 19 is set in a feed opening 3 of clothes as shown in the drawing, the hinge 19a of the drying shelf 19 gets into contact with a shelf-detection sensor 22 installed at the feed opening 3 of clothes and constituted of a piezoelectric element or the like and signal currents flow to detect the drying shelf 19. This detected signal is processed by a controller to drive a drive motor 18-1 for the shutter and open the shutter 18 by operating a drive cam 18-2 for the shutter. To the contrary, when the drying shelf 19 is removed from the feed opening 3 of clothes, the shutter 18 is closed. In this way, when the drying shelf 19 is set at the opening, the shutter is automatically opened and when it is removed from the opening, the shutter is automatically closed to execute a partly exhausting type drying.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer, and more particularly, to a drying chamber in which a drying shelf is detachably mounted, and a very small amount of clothing such as a wool sweater is placed on the drying shelf. It relates to improvement of a clothes dryer for drying.

2. Description of the Related Art One era ago, the mainstream of clothes dryers in Japan was the exhaust type, which had a simple structure and good drying efficiency, but the exhaust type exhausts all moisture contained in clothes to the room as humid air. Therefore, there are drawbacks such as the room getting wet and uncomfortable, and the room being moldy due to moisture.Currently, the dehumidifying type that does not emit moisture to the room by returning humid air to water with a heat exchanger and draining it It has become.

[0003] However, according to the dehumidification-type clothes dryer, although the humidity in the room is eliminated, the drying efficiency is inferior to that of the exhaust-type clothes dryer, the drying time is longer, and the power consumption is correspondingly reduced. There is a problem that the drying cost increases and the drying cost increases.

Therefore, in recent years, a ventilation path leading to the outside of the dryer frame has been provided in the circulation air path of the dehumidification-type clothes dryer so that it can be opened and closed. When the ventilation path is closed, the dehumidification type is opened. There has been proposed a clothes dryer employing an opening / closing lid that is partially switched to exhaust so that it can be used.

[0007] In this method, the clothes are placed on a drying shelf, so that the clothes can be dried only by the warm air without giving a mechanical rotating force to the clothes, and the clothes are protected from the shape collapse and the cloth shrinkage. When drying clothes such as sweaters using a drying shelf in a partially exhausted dehumidification-type clothes dryer, the drying time is reduced by about 20 to 30% compared to a normal dehumidification-type clothes dryer. It is confirmed that it can be done.

However, in the above-described conventional dehumidifying-type clothes dryer, even when the dryer is operated with a drying shelf installed in the drying chamber, a partially exhaust-type opening / closing lid is provided. If you do not open it, it is the same as general dehumidification drying, and although only a very small amount of clothing is dried, the drying efficiency is poor, the drying time is long, and the power consumption is correspondingly large. As a result, the drying cost increases.

Immediately after dehydration by the washing machine, the moisture contained in the clothing is about 45% of the weight of the clothing. As shown in FIG. 4, when 5.0 kg of the clothing is dehydrated by the fully automatic washing machine, the moisture is still 2.4.
If all of this is exhausted as humid air into the room, the room will be moist, giving people discomfort and the walls will mold, so it will be condensed as much as possible with the dehumidifying method, and the humid air into the room will be removed. Reduce. When dried by the dehumidification method, about 1.3 kg of water is discharged from the drain port 17-1 as water outside the machine. Leakage from the labyrinth seal and other seals to the outside of the machine can be reduced to about 1.1 kg, and the room cannot be closed. Ventilation ensures that people are not at a discomfort level or that the walls do not mold.

Therefore, when the moisture contained in the clothes is small, that is, when the clothes are dried outside and fresh-dried (dryness of 90% or more), the evaporating rate is increased if a partial exhaust method is used to dry the clothes. The time is short, the drying cost can be reduced, and the disadvantages of the dehumidification method can be minimized.

At the outer peripheral portion of the blower 8, the circulating air and the cooling air are separated by a labyrinth seal portion with the partition plate without entering and exiting. Heat exchanged between the sides
Part of the moisture contained in the circulating wind is condensed into water, flows into the circulation duct 17 from the casing discharge port 12-1 of the fan casing 12, and is discharged outside the machine from the drain port 17-1. Most of the moisture contained in the circulating air is exhausted from the exhaust port 17-2 of the circulating duct 17 to the outside of the machine, and outside air is sucked in instead of the exhausted air.

く、乾燥コストの点で有利である。
As described above, according to the present invention, in a partially exhausted type dehumidification-type clothes dryer, the drying time can be reduced by about 20 to 30% as compared with a normal dehumidification-type clothes dryer. At the time of drying, it is possible to prevent forgetting to open the partially exhaust switching type opening / closing lid by installing a drying shelf, to ensure partial exhaust drying, to always enjoy an efficient drying form, and to shorten the drying time However, the power consumption is small by that amount, which is advantageous in terms of the drying cost.
