Description

[0001] The present invention relates to an air cleaner having a humidifying function and a dehumidifying function,

The present invention relates to an air cleaner having a humidifying and dehumidifying function, and more particularly, to an air cleaner for sterilizing foreign substances such as fine dust and bacteria in the room air to supply clean air, Air purifier.

Indoor air, especially the indoor air, flows in and out through the opening / closing of doors, residents' moving and window ventilation. In the case of rain or in winter season, ventilation through windows is not done well, And such turbid room air may cause respiratory disease, allergic skin disease, headache, or the like to the occupant or may be unpleasant.

Therefore, it is necessary to circulate the air in a residential space or a work space where a person lives. For this reason, the building law enforces the installation of a ventilation system in a building. Such a ventilation system can be divided into a natural circulation type and a forced circulation type .

The natural circulation system has a disadvantage in that the circulation amount of the air is limited due to the ventilation system through the windows and the like and thus the ventilation is not sufficiently performed. Accordingly, recently, forced circulation type ventilation System, and an air purifier is one example of such a system.

Such an air cleaner sucks indoor air through a fan, and then filters and discharges the air through a filter or the like, thereby ventilating the indoor air. At the same time, the indoor air is cleaned. Most of the air cleaners have a filter, Therefore, in order to keep indoor air comfortably, it is inconvenient to separately provide a humidifier or a dehumidifier that can adjust the indoor humidity separately from the air purifier.

In order to solve the above inconvenience, an air purifier having a humidity control function as well as an air purifying function has been developed and used. As one example of such an air purifier, there is a multipurpose purifier having a humidifying and dehumidifying function disclosed in Japanese Patent Application No. 1175158 Air purifiers.

As shown in FIG. 1, the multipurpose air cleaner disclosed in the above patent document includes a main body 100 in the form of a rectangular box having a lid that can be opened and closed on an upper surface thereof and an outlet for discharging purified air at an upper portion of the front surface; A charcoal storage container 200 having a perforated structure and a plurality of holes formed on an entire surface of the main body 100, ; A partition plate installed in the middle of the inner wall of the main body so as to vertically divide the inner wall of the main body 100 and the outer wall of the char storage vessel 200; A blowing fan 300 mounted on the main body 100 below the partition plate to supply outside air to the inner char storage container 200; A heater 400 installed on a bottom surface of the main body 100 to heat the stored water and an ultrasonic vibrator for generating water vapor; A sterilizing lamp provided on an inner upper surface of the main body 100 to sterilize air purified through charcoal; And a valve that is provided on the outer surface of the main body to communicate with the bottom surface of the main body 100 and is capable of discharging the stored water to dehumidify or humidify the indoor air.

However, most conventional humidifying / dehumidifying air purifiers including the multipurpose air cleaner disclosed in the above-mentioned patent documents are provided with a humidifying water reservoir and a dehumidifying water reservoir separately. When water is fully charged in the dehumidifying water reservoir, If there is no water in the humidifying water tank, humidification is not done, so it is troublesome to replenish water frequently or empty the water tank.

In addition, although the conventional multi-function air cleaner has an air purifying function, it is disadvantageous in that it does not sufficiently remove fine dust and sufficiently sterilize by filtering out foreign substances through a filter or sterilizing using plasma.
