DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a control apparatus for a humidifying air purifier according to the present invention will be described with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a diagram illustrating a schematic configuration of a control apparatus for a humidifying air cleaner according to an embodiment of the present invention. Referring to FIG.

1, the controller of the humidifying air cleaner according to the present embodiment includes a water supply unit 110, an air humidification unit 120, a control unit 130, and a sterilizing unit 140. [

The humidifying air purifier according to an embodiment of the present invention sucks outside air through an air suction part and discharges the humidified air through a humidifying air discharging part. The air humidifying part 120 humidifying air introduced into the body of the humidifying air purifier And a water supply unit 110 for supplying water for humidification to the air humidifier unit 120.

In the humidifying air purifier according to the present embodiment, the air sucked into the main body is purified and humidified while passing through the humidifying part 120, and is discharged through the humidifying air discharging part.

The air suction unit is detached at the front of the main body, and filters the air sucked from the outside and transfers the air to the air humidifying unit 120. The air humidifying unit 120 humidifies the air introduced through the air suction unit . The air humidification unit 120 absorbs moisture by the water supplied from the water supply unit 110.

Although not shown in detail in the drawing, the air humidifying unit includes a desorption water tank (not shown) slidably attached to and detached from a humidifying / desorbing unit (not shown), a humidification module rotatably coupled to the desorption water tank (Not shown). The desorption water tank (not shown) receives water supplied from the water supply unit 110. Since the desiccant water tank (not shown) is slid through the desiccant opening (not shown) formed on the side surface of the main body, the air humidification unit 120 can be easily detached and attached, .

Meanwhile, the humidification module (not shown) is rotatably coupled to the desorption water tank (not shown) to humidify air sucked through the air suction unit. To this end, the humidification module (not shown) absorbs water while being wetted by the water supplied from the water supply part 110, and improves absorption and diffusion of water through rotation.

In this embodiment, the water supply unit 110 sterilizes the water stored in the water supply unit 110 and selectively supplies the water to the humidification module (not shown) of the air humidification unit 120.

The water supply unit 110 includes a water supply member (not shown) that is detachably attached to the main body, a water supply member (not shown) for selectively flowing water from the water supply member (not shown) And sterilizing unit 140 for sterilizing water contained in the water (not shown). The water supply unit 110 continuously sterilizes the water in the water tub member (not shown) by the sterilizing unit 140, and sterilized water is supplied to the air humidification unit 120 through a water supply member (not shown) To the humidifying module (not shown).

For reference, the water bottle member (not shown) is provided in a transparent or translucent form so that the user can check the inside of the water bottle member, and the sterilizing unit 140 is coupled to the inside of the water bottle member. This allows the user to easily check the water level of the water bottle member (not shown), and also allows the user to visually confirm the state in which water stored in the water bottle member (not shown) is sterilized by the sterilizing unit 140 The sterilization reliability of the product can be further improved.

In this embodiment, the sterilizing unit 140 sterilizes water contained in a water supply unit (not shown) of the water supply unit 110 using an electrolysis method.

However, the sterilization method using electrolysis has a disadvantage that a disinfection odor (e.g., a smell) is generated when excessive electrolysis is performed. Accordingly, the present embodiment provides a control device and method for securing water sterilization power through electrolysis of water while at the same time preventing the generation of disinfection odor due to excessive electrolysis.

Hereinafter, a method of sterilizing the control unit 130 using an electrolysis method will be described with reference to FIGS. 2 to 4. FIG.

2 is a flowchart illustrating a method of controlling a humidifying air cleaner according to an embodiment of the present invention.

As shown in FIG. 2, when the power button is inputted in the waiting state of the humidifying air purifier (S101), the controller 130 enters the air purifying (hearing) mode (S102).

When the humidification button is inputted in the state of entering the air cleaning (air-purifying) mode as described above (S103), the humidification mode is entered (S104).

When the humidifying air purifier enters the humidification mode as described above, the controller 130 checks the seating state of the water bottle member (not shown) (S105).

E.g., whether the water bottle (i.e., the water bottle member) is properly seated, water is contained in the water bottle, and the like.

When the seating state of the bucket member (not shown) is normal as described above (YES in S105), the controller 130 controls the electrolysis current in the initial stage of sterilization (that is, the initial stage of electrolysis) The electrolysis is performed for the predetermined electrolysis time (i.e., the electrolysis time) in response to the feedback current (S106).

The electrolysis time to be carried out in accordance with the electrolytic current can be carried out based on the condition table as shown in Fig.

3 is a diagram illustrating a condition table for performing electrolysis according to an embodiment of the present invention, and FIG. 4 is a timing chart illustrating an electrolysis method according to an embodiment of the present invention .

3 and 4, the sterilizing power of water is secured through electrolysis and the generation of disinfection odor due to excessive electrolysis is prevented .

3 and 4, the controller 130 performs initial electrolysis after initialization of the humidifying air cleaner (for example, after initialization of an electrolysis operation such as re-input of a power cord or re-insertion of a water bottle) In case of carrying out, electrolysis is carried out for the pre-specified operating time, and then it is kept in the waiting state for the specified pause time.

The operating time depends on the magnitude of the electrolytic current (i.e., the feedback current through the water in the bucket member).

For example, when the electrolytic current is 0.7 A (second reference electrolytic current) or more, the operation time is 3 minutes. When the electrolytic current is 0.35 A (first reference electrolytic current) or more, the operation time is 5 minutes. When the electrolytic current is less than 0.35 A, Is electrolyzed for 9 minutes. Here, the operation time (i.e., the electrolysis execution time) according to the electrolytic current can be derived through testing, and is an exemplary value, and thus may be changed in another embodiment.

After the initial one-time electrolysis (e.g., from the second electrolysis), the operating time (i.e., electrolysis time) is relatively short (i.e., relative to the initial one) Perform electrolysis.

For example, when the electrolytic current is 0.35 A (the first reference electrolytic current) or more, the operation time is 1 minute, and when the electrolytic current is less than 0.35 A, the operation time is 2 minutes. Here, the operation time (i.e., the electrolysis execution time) according to the electrolytic current can be derived through testing, and is an exemplary value, and thus may be changed in another embodiment.

At this time, the dwell time between the operation time (i.e., the electrolysis execution time) may be set to 3 hours (i.e., the electrolysis cycle may be set at 3 hour intervals) For example, operation stop, dehumidification mode release, automatic sterilization stop, etc.) can be applied.

Accordingly, when it is assumed that the humidifying air purifier is operated for 10 hours, a total of four electrolytic operations including a rest time can be performed.

Herein, the dwell time can be derived through testing, and is an exemplary value, so it may be changed in other embodiments.

As described above, according to the present embodiment, the sterilizing power of water is secured through the electrolysis of water in the water tank of the humidifying air purifier which can purify and humidify the air sucked from the outside, and at the same time, the disinfection odor due to excessive electrolysis Can be prevented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, I will understand the point.
