Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order that those skilled in the art can easily carry out the present invention. In the following detailed description of the preferred embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In the drawings, like reference numerals are used throughout the drawings.

In addition, in the entire specification, when a part is referred to as being 'connected' to another part, it may be referred to as 'indirectly connected' not only with 'directly connected' . Also, to "include" an element means that it may include other elements, rather than excluding other elements, unless specifically stated otherwise.

1 is a configuration diagram of an air purifier capable of recognizing a filter according to an embodiment of the present invention.

Referring to FIG. 1, an air purifier 100 capable of recognizing a filter according to an embodiment of the present invention includes a transmitter 110, a filter 120, a filter recognizer 130, a controller 140, (150) and a display unit (160).

The blowing fan 110 may be configured to include an air blowing fan and a motor for driving the air blowing fan 110 so that external air flows into the air purifier 100 by forming a flow of air.

Here, the blowing fan can be rotated by the motor to form a flow of air. In addition, the rotation speed of the motor (i.e., revolutions per minute (RPM)) can be controlled by the control unit 140. [

The filter unit 120 filters the contaminants contained in the air flowing into the air cleaner 100. For example, the filter unit 120 may be configured to adsorb contaminants in the air flowing into the air cleaner 100 And so on.

The filter unit 120 may include one or more filters. For example, various types of filters such as a prefilter, a functional filter, a HEPA filter, a deodorization filter, Can be mounted. Here, the pretreatment filter is for removing relatively large dust, hair, and pet hair, and the functional filter is for removing antibacterial, pollen, house dust mite, bacteria, bacteria, etc., and the HEPA filter is used for removing fine dust, And the deodorization filter is for removing various odors and noxious gases in the room.

In addition, the filter unit 120 may be configured by mounting filters of various capacities. Here, the capacity of the filter may vary depending on the area, height, depth, etc. of the filter.

The filter recognition unit 130 is for recognizing the type or capacity of the filter mounted on the filter unit 120.

For example, each filter mounted on the filter unit 120 is provided with an identification unit (for example, an identification tag, a specific projection, predetermined color, etc.) for identifying the type of the filter, 130 can identify the type of filter mounted on the filter unit 120 using means for recognizing the identification unit provided in the filter (for example, tag recognition means, projection detection means, color recognition means, etc.) .

In another example, the filter recognition unit 130 recognizes the area, height, depth, and the like of each filter mounted on the filter unit 120 through various sensors (for example, a magnet sensor or the like) can do.

In addition, when the type or capacity of the filter is not identified according to the above description, the filter recognition unit 130 may recognize that the filter is not properly installed in the filter unit 120. [

The control unit 140 controls the operation of the air cleaner 100 and includes a central processing unit (CPU), a graphics processing unit (GPU), a microprocessor, an application specific integrated circuit (ASIC) Programmable gate arrays (FPGAs), and the like.

Specifically, when the filter is installed in the filter unit 120, the control unit 140 may change the control setting value for the operation of the air cleaner 100 according to the type or capacity of the filter recognized by the filter recognition unit 130 Can be set. Here, the control set value for the operation of the air cleaner 100 may be set to a predetermined value based on a default value of the rotational speed of the motor of the blower 110 (for example, a rotational speed setting value for each blowing step, (For example, use time, flow rate, etc.) for determining the replacement cycle of the battery.

In addition, the control unit 140 can control the cleaning function of the air cleaner 100, the determination of the replacement period of the filter, and the alarm function according to the control set values set differently according to the type or capacity of the filter. The function of the air cleaner 100 is well known to those skilled in the art, and thus a detailed description thereof will be omitted.

The storage unit 150 is for storing information necessary for control setting of the air cleaner 100 and may be implemented, for example, as a non-volatile memory (e.g., ROM, flash memory, etc.).

For example, the storage unit 150 may store control setting value information that is determined differently according to the type or capacity of the filter.

The display unit 160 displays information related to the operation of the air cleaner 100 under the control of the controller 140 and provides the information to the user. For example, the display unit 160 may be implemented as an LED panel, a touch screen, or the like.

For example, the display unit 160 may display the type or capacity information of the filter recognized by the filter recognition unit 130.

As another example, the display unit 160 may notify the user through the filter abnormal mounting alarm information display if the filter recognizing unit 130 recognizes that the filter is not normally mounted.

2 is a flowchart of a control setting method of an air cleaner capable of recognizing a filter according to another embodiment of the present invention.

Referring to FIG. 2, when a filter is installed in the filter unit of the air cleaner (S21), the filter is recognized (S22). Here, the recognition of the filter can recognize the type or capacity of the filter, and in addition, recognize that the filter is not normally mounted.

Thereafter, the control setting value of the air cleaner is set according to the filter recognition result (S23), the operation of the air cleaner can be performed according to the control setting value (S24), and if necessary, the operation information of the air cleaner is displayed (S25).

The control setting method described above with reference to Fig. 2 can be performed by the air purifier shown in Fig. 2 are the same as those described above with reference to FIG. 1, so that a duplicate description thereof will be omitted.

The present invention is not limited to the above-described embodiments and the accompanying drawings. It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
