DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. In the following description, 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.

The present invention will be described below with respect to the air cleaner and its filter life indication method. In particular, the present invention proposes an air cleaner and a filter life display method thereof for displaying the remaining life of the filter step by step using the filter remaining life indicator. In this way, the user can check the remaining life of the filter to recognize the specific replacement time of the filter.

1 is a block diagram showing the configuration of an air cleaner according to an embodiment of the present invention.

As shown, the air cleaner includes a control unit 100, a memory 110, an input unit 120, a display unit 130, a filter life determination unit 140, a fan driver 150, and a filter unit 160. do.

Referring to FIG. 1, the controller 100 controls the overall operation of the air cleaner, and controls a function for displaying the remaining life of the filter step by step using the filter remaining life indicator according to an embodiment of the present invention. And processing.

The memory 110 stores a program and various data for the overall operation of the air cleaner.

The input unit 120 includes a plurality of function keys, and provides a control signal corresponding to a key pressed by the user to the controller 100. In addition, the input unit 120 may be configured as a wireless communication device, for example, an infrared sensor so as to receive various control signals through a remote control.

The display unit 130 displays status information generated during operation of the air cleaner and limited numbers and letters. In particular, the display unit 130 displays a filter remaining life indicator according to an embodiment of the present invention. crystal display).

The filter life determiner 140 detects an operating state of the fan driving unit 150 to determine a service life of the filter, and determines a remaining life of the filter based on a predetermined maximum available life and a difference between the determined service life. . Here, the operation state of the fan driving unit 150 may be sensed using various sensors, for example, an operating time of the motor for driving a fan (not shown), operating intensity, and the like, and stored in a memory. Based on the air volume by intensity, the product life of the filter can be determined by accumulating the product of the air volume of the operating intensity and the operating time. Here, the air volume means the amount of air sucked for a unit time and passes through the filter. The filter life determination unit 140 calculates a percentage of the remaining life for the maximum available life to determine the remaining life ratio, and displays the filter remaining life indicator on the display unit 130 according to the determined remaining life ratio to display the filter. Displays the remaining life in stages. Here, the filter remaining life indicator is composed of a plurality of remaining life indicator bars, and as the determined remaining life ratio decreases, the remaining life indicator bars displayed on the filter remaining life indicator decreases. In addition, when there are a plurality of filters having different replacement cycles, the filter life determination unit 140 initializes the remaining life ratio of the filter having a short replacement cycle when the filter having a short replacement cycle is replaced, The remaining replacement cycle raises the remaining life rate of the long filter.

The fan driver 150 includes a motor and performs a function of driving a fan (not shown). Here, the fan (not shown) sucks contaminated air in the room and discharges the purified air to the room as the motor rotates.

The filter unit 160 is composed of a plurality of filters, and purifies the air sucked by the fan (not shown). For example, the filter unit 160 may include a pre-filter for removing a relatively large dust contained in air, a deodorizing filter for removing odors, a dust collecting filter for collecting dust by electric action, a hepa filter for removing fine dust, and ultraviolet rays. It may include at least one of the ultraviolet filter for disinfecting the air using.

2 is a flowchart illustrating a filter life display method of an air cleaner according to an embodiment of the present invention.

Referring to FIG. 2, as the power is turned on in step 201, the air cleaner senses an operation state of a motor for driving a fan in step 203 to determine a used life of the filter. For example, the air cleaner may detect the operation time and the operating intensity of the motor, and may calculate the product life of the filter by accumulating and calculating the product of the operating intensity and the operating time based on the amount of air for each strength stored in the memory. Here, the air volume means the amount of air sucked for a unit time and passes through the filter.

Then, the air cleaner determines the remaining life of the filter based on the difference between the predetermined maximum usable life and the determined service life in step 205.

Thereafter, the air cleaner calculates the percentage of the remaining life for the maximum usable life in step 207 to determine the remaining life ratio, as shown in Equation 1 below.

Figure pat00001

Thereafter, the air cleaner displays the remaining life of the filter on the display unit according to the remaining life ratio determined in steps 209 to 225. For example, as shown in FIG. 3A, the remaining filter life indicator in the form of a battery may be displayed on the display unit to display the remaining life of the filter step by step. The filter remaining life indicator is composed of a plurality of remaining life indicator bars, and as the determined remaining life ratio decreases, the remaining life indicator bars displayed on the filter remaining life indicator decrease as shown in FIG. do. This will be described in detail below, and the following description will be given by taking an example of a filter remaining life indicator composed of four remaining life indicator bars.

First, the air purifier checks in step 209 whether the determined residual life rate is greater than a first threshold (eg, 75%).

In step 209, when the determined remaining life ratio is greater than the first threshold, the air cleaner displays all four remaining life indicator bars of the filter remaining life indicator in step 211, and returns to step 203 to perform the following steps. Repeat it. Accordingly, the user can recognize that the remaining life of the filter is 75% or more by checking the four remaining life indicator bars of the filter remaining life indicator.

On the other hand, in step 209, when the determined remaining life ratio is not greater than the first threshold, the air cleaner determines whether the determined remaining life ratio is greater than a second threshold (eg, 50%) in step 213. do.

In step 213, if the determined remaining life ratio is greater than the second threshold, the air cleaner displays three remaining life indicator bars of the four remaining life indicator bars of the filter remaining life indicator in step 215, and the 203. Return to step and repeat steps below. Accordingly, the user can recognize that the remaining life of the filter is 50% or more by checking the three remaining life indicator bars of the filter remaining life indicator.

On the other hand, in step 213, if the determined remaining life ratio is not greater than the second threshold, the air cleaner determines whether the determined remaining life ratio is greater than a third threshold (eg, 25%) in step 217. do.

In step 217, when the determined residual life ratio is greater than a third threshold, the air cleaner displays two remaining life indicator bars of the four remaining life indicator bars of the filter remaining life indicator in step 219, and the 203. Return to step and repeat steps below. Accordingly, the user can recognize that the remaining life of the filter is 25% or more by checking the two remaining life indicator bars of the filter remaining life indicator.

On the other hand, in step 217, if the determined residual life ratio is not greater than a third threshold, the air cleaner determines whether the determined residual life ratio is greater than a fourth threshold (eg, 0%) in step 221. do.

In step 221, when the determined remaining life ratio is greater than a fourth threshold, the air cleaner displays one remaining life indicator bar among four remaining life indicator bars of the filter remaining life indicator in step 223, and the 203. Return to step and repeat steps below. Accordingly, the user can recognize that the remaining life of the filter is 0% or more by checking one remaining life indicator bar of the filter remaining life indicator.

On the other hand, in step 221, when the determined residual life ratio is not greater than a fourth threshold, the air cleaner displays zero remaining life indicator bars among four remaining life indicator bars of the filter remaining life indicator in step 225. . That is, all four remaining life indicator bars of the filter remaining life indicator are not displayed. Accordingly, the user can recognize that the remaining life of the filter is 0% or less and it is time to replace the filter by checking the zero remaining life indicator bars of the filter remaining life indicator.

The air cleaner then terminates the algorithm according to the invention.

On the other hand, the air cleaner may be composed of a plurality of filters, the replacement cycle for each filter may be different. For example, a pre-filter disposed at the outermost side to remove relatively large dust contained in air may have a shorter replacement cycle than other filters, and a hepa filter disposed relatively inside to remove fine dust. In this case, the replacement cycle may be relatively long compared to other filters. Therefore, it is necessary to display the remaining life of each filter so that the user can identify the remaining life of each filter to distinguish between the filter that needs to be replaced and the filter that does not need to be replaced.

To this end, the present invention further proposes an air cleaner and a filter life display method thereof for displaying the remaining life of the filter step by step using the filter remaining life indicator for each filter. Here, the replacement of the filter having a short replacement cycle affects the remaining life ratio of the filter having a long replacement cycle. For example, an air cleaner consisting of an A filter with a replacement cycle of 3 months and a B filter with a replacement cycle of 12 months, if you replace the A filter after 3 months of use, the replacement cycle is Less dust collection can be achieved with a 12 month B filter, which increases the remaining life of the B filter with a 12 month replacement cycle. Therefore, if a filter having a relatively short replacement cycle is replaced, it is necessary to increase the remaining life ratio of the filter having a long replacement cycle. On the other hand, replacing a filter with a relatively long replacement cycle does not affect the percentage of life remaining of a filter with a short replacement cycle.

4 is a flowchart illustrating a method of displaying a life of each filter having a different replacement cycle of the air cleaner according to an embodiment of the present invention.

Referring to FIG. 4, in step 401, the air cleaner determines the remaining life ratio of the filter for each of the plurality of filters having different replacement cycles, and the remaining filter ratio according to the determined remaining life ratio. Display the remaining life indicator bar on the life indicator. For example, for an air cleaner consisting of an A filter with a replacement cycle of 3 months and a B filter with a replacement cycle of 12 months, determine the remaining lifespan ratio of the A and B filters, and determine the A, B Display the remaining life indicator bar on the filter remaining life indicator for the filter.

Thereafter, the air cleaner determines whether the A filter having a short replacement period is replaced in step 403.

When it is determined in step 403 that the A filter having a relatively short replacement period is not replaced, the air cleaner determines whether the B filter having a relatively long replacement period is replaced in step 405.

In step 405, when it is determined that the B filter with a relatively long replacement period is not replaced together with the A filter with a shorter replacement period, the air cleaner returns to step 401 and repeats the following steps.

On the other hand, when it is determined in step 405 that the A filter having a short replacement period is not replaced but the B filter having a long replacement period is replaced, the air cleaner determines the remaining life ratio of the B filter in step 407. After initializing to 100%, the process returns to step 401 and repeats the following steps. As such, replacement of a B filter with a relatively long replacement cycle does not affect the percentage of life remaining of the A filter with a shorter replacement cycle.

In contrast, when it is determined in step 403 that the A filter having a relatively short replacement period is replaced, the air cleaner determines whether the B filter having a relatively long replacement period is also replaced in step 409.

In step 409, when it is determined that the A filter having a short replacement period is replaced but the B filter having a long replacement period is not replaced, the air cleaner measures the remaining life ratio of the A filter at 100 in step 411. After initializing to% and increasing the residual life ratio of the B filter, as shown in Equation 2, the process returns to step 401 and repeats the following steps.

Figure pat00002

As such, the replacement of the A filter with a relatively short replacement cycle affects the remaining life ratio of the B filter with a long replacement cycle, thereby raising the residual life ratio of the B filter with the long replacement cycle. When the remaining life ratio of the B filter increases, the remaining life indicator bar displayed on the corresponding filter remaining life indicator may increase, or may be maintained according to the existing remaining life ratio.

On the other hand, when it is determined in step 409 that the B filter having a relatively long replacement period is also replaced together with the A filter having a shorter replacement period, the air cleaner determines the remaining life ratio of the A filter and the B filter in step 413. After initializing the remaining life ratio of each to 100%, go back to step 401 and repeat the following steps.

Figure 5 is an exemplary view showing a comparison of the residual life ratio with time of the air cleaner according to an embodiment of the present invention and the prior art.

Referring to FIG. 5, the air filter comprising an A filter having a replacement cycle of 3 months and a B filter having a replacement cycle of 12 months, when the prior art is applied, the remaining life of the B filter having a replacement cycle of 12 months The rate decreases constantly with time, regardless of the replacement of the A filter with a replacement cycle of 3 months. Accordingly, despite the fact that the new filter A has less dust collection on the B filter and the remaining life of the B filter is increased, the air purifier has come to replace the B filter after 12 months of the B filter replacement cycle. You will be informed. However, when the present invention is applied, as the remaining life ratio of the B filter having the replacement cycle of 12 months is increased by the replacement of the A filter having the replacement cycle of 3 months, it is possible to recognize the user with a more accurate replacement time. Through this, the present invention can prevent unnecessary frequent replacement of the filter having a relatively long replacement cycle.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention. Therefore, the scope of the present invention should not be limited by the illustrated embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
