2. Description of the Related Art Conventionally, as this type of dust collecting apparatus, there is an electric vacuum cleaner generally used at home. This vacuum cleaner has a suction fan for sucking air into the main body, a dust collecting means for collecting dust sucked from a suction nozzle, an exhaust port downstream of the suction fan, and a suction hose upstream of the suction fan. A suction nozzle that communicates and sucks dust is provided. When using this electric vacuum cleaner to clean dust on the floor of the room, etc., the clothes basket, small articles such as a trash box, chairs, etc., which are placed on the floor of the room, are cleaned manually. Since the suction width of the dust on the floor depends on the width of the suction nozzle, the dust on the entire floor or the portion to be cleaned is sucked while reciprocating the suction nozzle.

Further, when cleaning dust accumulated on the surface of a washing machine, a washing unit, an object stand, etc., a dedicated suction nozzle with a brush is used to collect the dust or wipe it with a rag.

In the case of dehumidifying the room, the heat pump type dehumidifier having a basic system composed of a compressor, an evaporator and a condenser is operated to remove water from the room.

Further, in the case of drying clothes, the clothes are dried in the clothes-drying place in the sun and dried by using a clothes dryer having an air-cooling dehumidifying function in which indoor air is used as cooling air.

[0006]

However, in the electric vacuum cleaner of the prior art described above, the person who cleans the suction nozzle of the electric vacuum cleaner does not clean the entire floor surface or the surface of the portion to be cleaned. It is necessary to move it. This method requires manual work, is time-consuming and labor-intensive, and is a chore. Further, it is necessary to perform the cleaning work while cleaning up small items, cushions, chairs, etc. placed on the floor surface, which requires much more labor for the cleaning work.

Further, since the suction nozzle does not reach the upper part of the upper part of the washbasin unit, the storage table, etc., the dust accumulated on the surface is often left uncleaned and accumulated. When cleaning this part, it is necessary to prepare a step and ride on it to perform the cleaning work, which has a problem that workability is extremely poor.

Further, when dehumidifying indoor water by using a dehumidifier, heat is released into the room and the temperature in the room rises, so that the humidity decreases but it is uncomfortable. Especially when driving in relatively high temperatures such as the rainy season and summer, the discomfort becomes even stronger.

Further, when clothes are dried by a clothes dryer, the heat of the heater used for drying is used for drying clothes as in the dehumidifier, but the heat is released into the room and the temperature in the room rises, which is uncomfortable. is there.

Further, since the collection of dust in the room, the dehumidification of the room, and the drying of clothes are carried out by respective dedicated devices, it is necessary to move the device to a required place each time the device is installed or used. And it was inconvenient to use.

The present invention solves the above-mentioned conventional problems, and has a dust collecting function of automatically collecting dust accumulated on the floor surface of the room and the surfaces of the washing machine, the washing unit, the table, and the like. It is an object of the present invention to provide a device with a dust collecting device that has at least one of a dehumidifying function of dehumidifying indoor humidity and a drying function of drying clothes.

2 is different from the structure of FIG. 2 in that the structure of the dehumidifying means is different and an adsorbent is used. The dehumidifying method for dehumidifying the indoor air and drying the object to be dried will be described. First, in order to adsorb moisture in the air, the flow path switching means 17 is set to the a side, and the dehumidifying means 15 is allowed to pass air for a certain time. When a certain amount of water is adsorbed on the adsorbent, which is the dehumidifying means 15, the regenerating process starts. The regeneration process is heating means 16
And the flow path switching means 17 is switched to the b side. The air taken in through the intake port 4 is heated by the heating means 16 and releases the moisture adsorbed by the dehumidifying means 15. The hot and humid air passes through the exhaust port 18, the exhaust passage 19, and the exhaust port 20 and is discharged outdoors. After continuing this regeneration process for a certain period of time, the adsorption process is performed again. By repeating this adsorption and regeneration, the room is dehumidified.

As described above, since the dehumidifying means 15 is provided, dehumidification in the room and dehumidification during drying can be performed, and the humidity environment in the room does not deteriorate. Furthermore, the dust that has become lighter is more likely to scatter, and the dust collection efficiency is improved.
