Description

An apparatus that guides how to use an air purifier, and a medium storing a program to run a method that guides how to use an air purifier}

The present invention relates to an apparatus for guiding a user of an air purifier on how to properly use the air purifier, and a medium on which a program for executing the method for guiding how to use the air purifier is recorded.

An air purifier is a device that sucks polluted indoor air, purifies the air using a filter, and discharges the purified air. That is, a filter is a key component in an air purifier.

However, if the method of using the air purifier is not appropriate, the lifespan of the filter may be shortened. Accordingly, the filter replacement cycle is shortened, which may cause unnecessary waste of resources and environmental pollution due to garbage discharge. In addition, the filter replacement cost increases, which may be a complaint of users who use air purifiers. Users' complaints may cause distrust in the product. In addition, the burden on product producers increases as post-service costs increase due to complaints from users to service centers or inquiries about product use.

As a case in which the method of using the air purifier is not appropriate, there is a case where the air purifier is operated in an environment where a lot of smell is generated, such as during cooking. In this case, the smell is attached to the filter, which reduces the use time of the filter.

In the prior art, a control method such as forcibly stopping an operation of an air purifier after detecting a smell or gas has been used. However, this conventional method, as a result, does not prevent contamination of the filter, and may also occur in cases where the operation is not in accordance with the user's intention.

When the mobile terminal (300 in FIG. 1) or the user terminal (400 in FIG. 1) performs step S300, the mobile terminal (300 in FIG. 1) or the user terminal (400 in FIG. 1) uses the result stored in step S200. The air purifier (100 in FIG. 1) connected to itself and transmitting the second data (data2) or the third data (data3) can determine whether the number of days satisfying the operating condition during cooking during the set period is equal to or greater than the reference date. there is.

Next, a notification may be sent to the user (step S400). The notification sent in step S400 may be in the form of a pop-up message or e-mail. In addition, the contents of the notification sent in step S400 are that the air purifier is currently being used during cooking, that the life of the filter can be shortened if the air purifier is used during cooking, and that the air purifier is used if the fine dust concentration is not high. It may include any one or more of the fact that it is more preferable to cook while ventilating without cooking.

Step S400 may be transmitted at an arbitrarily determined time during the day or when a time period to be determined starts. Accordingly, the user of the air purifier can stop the operation of the air purifier before he/she starts cooking, and as a result, the life of the filter of the air purifier can be prevented from being shortened due to odors generated during cooking.

Depending on the embodiment, the notification sent in step S400 is a link capable of stopping the operation of the air purifier at the time the user receives the notification message or at the time set by the user (eg, the time the user starts cooking). may also include

The service server (200 in FIG. 1) transmits the first message (msg_p) to the mobile terminal (300 in FIG. 1) or the second message (msg_m) to the user terminal (400 in FIG. 1), thereby completing step S400. can be done

The air purifier ( 100 in FIG. 1 ) may perform step S400 by generating a visual and/or audible notification through a user interface ( 150 in FIG. 2 ).

The mobile terminal (300 in FIG. 1) or the user terminal (400 in FIG. 1) may perform step S400 by displaying a predetermined message.

FIG. 5 is an operational flowchart for explaining a method of collecting driving data during cooking among the methods shown in FIG. 4 . Each step shown in FIG. 5 may be performed by the service server 200, the mobile terminal 300, or the control unit 520 of the user terminal 400, or the control unit of the air purifier 100 (130 in FIG. 2). may be performed by

Hereinafter, what is performed in the service server (200 in FIG. 1) will be described as an example.

First, data for each viewpoint may be generated based on the first data (step S210). A time point serving as a criterion for generating data for each time point may be arbitrarily selected. For example, data for each time point may be generated every hour. The first data generated by the air purifier ( 100 in FIG. 1 ) may include odor contamination and information on whether the air purifier is operating. The service server (200 in FIG. 1 ) converts the average value of odor contamination levels of the first data generated (or received) between 4:00 and 5:00 and information indicating whether the air purifier is operating at 5:00 as 5:00 data. can be created and saved. The service server ( 200 in FIG. 1 ) may generate hourly data for each of the plurality of air purifiers in the same manner and store the generated hourly data in association with a unique number of each of the plurality of air purifiers.

Next, it is determined whether or not the air purifier is in an operating state during cooking based on the nth time point data and the n−1th time point data, and based on the determination result, operation data during cooking may be collected (step S220).

For example, the service server determines the odor contamination degree of the n-th time point data (eg, the average value of odor contamination degrees from the n-1 th time point to the n-th time point data), the odor contamination degree of the n-th time point data (eg, , the average value of odor contamination from the n-2th point to the n-1th point), and if the air purifier continues to operate during the time period to be determined, it is determined that the air purifier satisfies the operation condition during cooking. can do. Here, the n-th point of view may be any one point in time within the time period to be determined. That is, when the odor contamination degree rapidly increases within the time period to be determined, it may be determined that the odor contamination degree increases as cooking is performed. Instead of determining whether the air purifier continues to operate during the time period to be determined, it may be determined whether the air purifier is operating at the nth point in time.

The service server may additionally consider a condition in which the odor pollution level of the n-1 th time data is not zero. That is, if the odor contamination degree of the n-1th point of time data is 0, it can be considered that the air purifier is not in operation, so it can be determined that the user of the air purifier does not need to perform step S400 of FIG. 4 .

The air purifier 100 , the mobile terminal 300 , or the user terminal 400 may also collect driving data while cooking in a manner similar to that described above.

As described above, the present invention has been described with reference to the drawings illustrated, but the present invention is not limited by the embodiments and drawings disclosed in this specification, and various modifications are made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that variations can be made. In addition, although the operational effects according to the configuration of the present invention have not been explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the corresponding configuration should also be recognized.
