Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an indoor dehumidifier. More specifically, the present invention relates to an underfloor dehumidifying unit that is installed under the floor to dry laundry, dehumidify a room, prevent dew condensation, and the like.

[0002]

2. Description of the Related Art Hitherto, as a dehumidifier used indoors, those used for drying clothes, bedding and the like are known. For example, JP-A-2-142510, JP-A-6-7597, JP-A-6-81497, JP-A-Hei 1
Techniques related to the above are described in each gazette such as 0-305195. In each of the above prior arts, a drying room for storing laundry hung on a hanger and bedding hung on a support bar, a drying air blowing device for blowing drying air into the drying room, and a drying room. A clothes drying device including a dehumidifier for dehumidifying exhausted moist air is disclosed.

That is, after a drying chamber, a drying air blowing device, and a dehumidifying device constitute a circulation path, the air dehumidified by the dehumidifying device is heated by heating means or mixed with the outside air. Then, the air is blown into the drying chamber again as drying air, and this is repeated to dry the laundry.
On the other hand, Japanese Utility Model Application Laid-Open No. 5-78798 discloses an underfloor storage in which a dehumidifier is installed inside a below-floor storage and the dehumidifier is combined with a ventilation fan with a damper to dehumidify the inside of the storage.

[0004]

The above-mentioned clothes drying apparatus including a dehumidifying apparatus is generally used indoors, but the apparatus occupies a large space, and is used particularly in a relatively small place such as a washroom. Sometimes there is a problem that it is difficult to use. In addition, portable indoor dehumidifiers have already been put into practical use not only for drying clothes but also for dehumidifying closed rooms and preventing dew condensation in winter. There is still a problem in terms of utilization. On the other hand, the underfloor storage in which the dehumidifier is installed is for the purpose of preventing decay of stored items stored in the storage, and therefore, it is difficult to cope with other purposes. The present invention has been conceived under such a situation, and it is possible to effectively use a floor surface and to effectively dry clothes, dehumidify and dry a room, and prevent dew condensation. It is an object of the present invention to provide a compact dehumidifier that can be used.

[0005]

According to the present invention, the following technical measures are taken to solve the above-mentioned problems. That is, according to the present invention, there is provided a dehumidifier, a dehumidifying unit including a box housing the dehumidifier, and a lid covering an upper opening of the box, wherein the dehumidifying unit includes the lid and the floor surface. Are installed under the floor so as to be substantially flush with each other, and the lid is provided with an intake port and a first exhaust port.
With such a configuration, indoor air including humidity is introduced into the dehumidifier from the intake port, and after being dehumidified in the dehumidifier, is again blown into the room from the first exhaust port as drying air, Thus, indoor dehumidification is performed.

Further, it is preferable to provide a second exhaust port in a side surface portion located below the floor of the box. The second exhaust port is provided for exhausting the exhaust gas from the dehumidifier to the outside, and can be used selectively or simultaneously with the first exhaust port. Particularly in summer, by using the second exhaust port, it is possible to prevent a temperature rise in the room due to exhaust heat.

In addition, it is preferable that the intake port and the first exhaust port provided substantially on the same plane as the floor have a lattice structure which can be opened and closed. In this way, when the underfloor dehumidifying unit of the present invention is not used, the intake port and the exhaust port can be closed to prevent dust and dirt from entering the unit. Further, it is preferable to provide a filter on the back surface of the intake port and the first exhaust port having the openable and closable lattice structure. By detachably mounting the filter, even when the present unit is used, it is possible to more reliably prevent dust and dirt from entering the inside.

[0008] A compressor type heat exchanger can be used as the dehumidifier. In this system, the humid air from the room is cooled in a cooling unit through which a refrigerant such as compressed Freon flows, and the moisture is separated as condensed water.
After cooling, the air from which the moisture has been separated is heated by the heat radiating section, and is again blown into the room through the exhaust port as drying air.

[0009] As the dehumidifier, a zeolite-type moisture adsorption device can be used. In this method, humid air from the room is brought into contact with a dehumidifying rotor carrying a special zeolite, and moisture is adsorbed to fine pores of the special zeolite to perform dehumidification. The adsorbed water is desorbed by heating the dehumidification rotor, and the dehumidification rotor regenerated after desorption of water can be used again for water adsorption.

The box housing the dehumidifier is usually a substantially rectangular parallelepiped. The entire top surface of the box is open, and the entire opening is covered with a lid. By doing so, the entire interior can be seen by removing the lid, so that the interior can be easily inspected and parts replacement of the dehumidifier can be easily performed. Furthermore, when the underfloor dehumidifying unit of the present invention is not used or becomes unnecessary, it can be effectively used as a underfloor storage.
