Description

A gas measuring device that proposes a customized filter, and an air purifier including the same {GAS SENSING DEVICE FOR SUGGESTING CUSTOMIZED FILTER AND AIR PURIFIER INCLUDING THE SAME}

The present invention relates to a gas measuring device that proposes a customized filter and an air purifier including the same, which proposes a customized filter corresponding to the detected harmful gas, and informs the replacement time of the filter according to the concentration data of the detected harmful gas. It relates to a gas measuring device that proposes a customized filter and an air purifier including the same.

In general, indoor air, which is not well ventilated, is always contaminated by various bacteria, dust, or harmful gas, and such indoor contaminants easily penetrate into the human body and act as a factor of occurrence of various diseases.

In recent years, there are many situations in which ventilation is not possible due to the influence of fine dust, and air purifiers are widely used not only in homes, but also in offices and stores.

An air purifier is a device that purifies contaminated air and converts it into fresh air. It refers to a device that passes air through a filter to remove dust and bacteria and remove bad odors. Specifically, the air purifier includes a gas sensor that detects harmful gas, a filter that purifies the harmful gas, and a display device that displays the gas information and the filter information. Accordingly, the user can know the replacement information of the filter provided in the air purifier or the detected harmful gas information. However, since such an air purifier is provided with one gas sensor and a filter corresponding thereto, it is difficult to detect various types of harmful gases.

Recently, in order to compensate for these shortcomings, an air purifier having a plurality of gas sensors has been developed. As a patent for such an air purifier, Korean Patent Registration No. 10-1695596 (hereinafter referred to as'Prior Art 1') It is known what has been described.

The air purifier of the prior art 1 includes a plurality of gas sensors, so that various types of harmful gases can be easily detected. However, the air purifier of the prior art 1 has a disadvantage in that when a plurality of gas sensors detects a plurality of harmful gases, it only guides the concentration of each harmful gas and cannot guide a customized filter corresponding to the harmful gas. In addition, since there is a limitation in the number of filters installed, there is a disadvantage in that all filters corresponding thereto are not provided even when various harmful gases are detected.

Recently, an air purifier that can be used by replacing a dedicated filter as necessary has been released. The air purifier includes a plurality of filters depending on the purpose, such as a filter for infants and filters for pets, and is optionally provided with a filter inside the air purifier. However, such an air purifier selects a filter after the user predicts the necessity, and the required filter may not be the same as the user's prediction. In this case, there is a disadvantage that the efficiency of the air purifier is deteriorated.

On the other hand, as a patent related to an air purifier related to the filter replacement indication, it is known that disclosed in Japanese Laid-Open Patent No. 2016-099369 (hereinafter referred to as “Prior Art 2”).

The air purifier of the prior art 2 includes a filter replacement lamp, so that the filter replacement lamp is turned on when the filter needs to be replaced. However, since the air purifier of the prior art 2 informs the replacement time based on the life of the input filter regardless of whether the filter is actually used or not, there is a disadvantage in that the filter replacement information is not accurate. In other words, there is a disadvantage that even an unused filter is replaced after a previously input time.

The above-described objects, features, and advantages will become more apparent through the following detailed description in connection with the accompanying drawings, and accordingly, a person having ordinary knowledge in the technical field to which the invention belongs will be able to easily implement the technical idea of the invention. .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a gas measurement device according to a preferred embodiment of the present invention, and FIG. 2 is a block diagram of an air purifier including the gas measurement device of FIG. 1.

Referring to FIGS. 1 and 2, the air purifier 1 purifies contaminated air and includes a gas measuring device 10 and a filter unit 20.

The gas measurement device 10 is a matching unit that detects harmful gases, and matches a detection unit 110 that detects different harmful gases, respectively, and a filter 210 corresponding to the harmful gas detected by the detection unit 110 It includes a guide unit 130 for guiding the filter 210 corresponding to the harmful gas detected by the 120 and the detection unit 110. In this case, the gas measuring device 10 may be provided inside the air purifier 1 or may be separately provided outside the air purifier 1. In addition, the filter 210 corresponding to the harmful gas may be the filter 210 included in the filter unit 20.

The sensing unit 110 includes a plurality of gas sensors 111 for detecting different harmful gases. For example, five gas sensors 111 may be provided to detect each of the five harmful gases, but the spirit of the present invention is not limited thereto.

The five harmful gases are representative five of the harmful gases, and refer to ammonia, acetic acid, acetaldehyde, toluene, and formaldehyde. In particular, among them, formaldehyde is a substance that causes atopy and respiratory diseases, and toluene is a substance that causes sick house syndrome. Accordingly, when there is a user with a specific disease, the harmful gas related to the disease may be input into the second storage unit 30 to be described later. The specific method will be described later.

The matching unit 120 stores a matching table in which a plurality of harmful gases and a plurality of filters 210 are matched. Specifically, in the matching table of the matching unit 120, all of the plurality of harmful gases detectable by the detection unit 110 are stored, and the filters 210 corresponding to each of the harmful gases are matched and stored. For example, in the matching table of the matching unit 120, a filter 210 is ammonia, b filter 210 is acetic acid, c filter 210 is acetaldehyde, d filter 210 is toluene, and e filter 210 Can be stored as corresponding to formaldehyde respectively. That is, information on the filter 210 corresponding to the harmful gas detectable by the detection unit 110 may be known through the matching unit 120.

When the detection unit 110 detects the harmful gas, the guide unit 130 may guide the filter 210 corresponding to the harmful gas detected by the detection unit 110 through the matching unit 120. In this case, the guide unit 130 may be guided by voice through a speaker or guided through a display through a screen. For example, when toluene is detected by the sensing unit 110 and the guiding unit 130 is provided as a speaker, the guiding unit 130 informs, "The filter corresponding to the detected toluene gas is a d filter." can do.

In addition, when a plurality of harmful gases are simultaneously sensed by the detection unit 110, the guide 130 may sequentially guide the harmful gases detected by the detection unit 110 according to concentration. Specifically, the guide unit 130 may guide a harmful gas having a high concentration among the harmful gases detected by the detection unit 110. For example, when toluene and formaldehyde are sensed by the sensing unit 110 and formaldehyde is detected at a higher concentration than toluene, the guide unit 130 indicates “The filter corresponding to the sensed formaldehyde is an e filter, The filter that corresponds to toluene is the d filter.”

When the concentration exceeding the reference value for each gas is detected by the detection unit 110, the gas exceeding the reference value may be guided through the guide unit 130. In this case, the reference value set in the sensing unit 110 may be differently determined according to the user. Specifically, if there is an atopy patient, the reference value of formaldehyde that causes atopy may be input to a lower value. Accordingly, the sensing unit 110 may guide through the guide unit 130 even when the formaldehyde is detected in a small concentration.

The accumulated concentration data of the harmful gas detected by the detection unit 110 is stored in the first storage unit 140. The first storage unit 140 accumulates and stores the harmful gas detected by the detection unit 110, and the accumulated data information of the first storage unit 140 can be transmitted to the outside through the first communication unit 150. have.

Meanwhile, the filter unit 20 includes a plurality of filters 210. Specifically, the filter unit 20 purifies harmful gases, and the filter 210 may be provided in the air purifier 1 to be replaced by a preset number. In this case, the number of filters 210 provided in the filter unit 20 may be less than the number of gas sensors 111 provided in the sensing unit 110. For example, when five gas sensors 111 are provided in the sensing unit 110 to detect five harmful gases, the filter unit 20 includes three filters 210 inside the air purifier 1 And, it is possible to separately store the two filters 210 outside the air purifier (1).

When a harmful gas is detected by the detection unit 110 and the filter 210 corresponding to the harmful gas detected by the guide unit 130 is guided, the filter 210 is not provided inside the air purifier 1 I can. At this time, any one of the filters 210 provided in the filter unit 20 may be replaced with the filter 210 guided by the guide unit 130. That is, the filter 210 that is not required can be replaced with the filter 210 guided by the guide unit 130 and used. For example, when a, b, c filter 210 is provided in the filter unit 20, acetaldehyde and formaldehyde are detected in the sensing unit 110, and c in acetaldehyde in the guide unit 130 When the filter 210 corresponds and the e filter 210 corresponds to formaldehyde, any one of the a and b filters 210 that are not required may be replaced with the e filter 210. That is, the filter 210 may be selectively mounted on the filter unit 20 according to the gas sensed by the detection unit 110 and the matching result stored in the matching unit 120.

The information of the filter 210 is stored in the second storage unit 30. The second storage unit 30 stores the remaining life of each filter 210, and may communicate with the gas measurement device 10 through the second communication unit 40. Specifically, the second storage unit 30 may receive the accumulated concentration of the harmful gas stored in the first storage unit 140 and calculate the remaining life of the filter 210. For example, the second storage unit 30 subtracts the accumulated concentration data of the harmful gas corresponding to each filter 210 received from the first storage unit 140 from the available time of each filter 210 to filter. The remaining life of 210 can be saved. Accordingly, the remaining life of the filter 210 corresponding to the undetected harmful gas during the remaining life of the filter 210 stored in the second storage unit 30 may be stored without decreasing.

Information of any one of the sensing unit 110, the filter unit 20, and the guide unit 130 is displayed through the display unit 50. The display unit 50 displays information on the harmful gas detected to the outside, information on the filter 210, or information on the customized filter 210 guided through the guide unit 130, and includes a display 510 or a speaker ( 520). For example, the display unit 50 displays the remaining life of the filter 210 calculated according to the accumulated concentration data of the harmful gas through the display 510, or through the speaker 520 according to the accumulated concentration data of the harmful gas. It may inform whether the calculated filter 210 needs to be replaced.

In addition, when a harmful gas related to a specific disease stored in the second storage unit 30 is detected by the detection unit 110, the display unit 50 may highlight and display the harmful gas information. For example, when atopy is input to the second storage unit 30, when formaldehyde causing atopy is detected by the detection unit 110, the display unit 50 indicates that the detected harmful gas is formaldehyde. They can be displayed in color or in different voices. Accordingly, the harmful gas information required by the user can be more effectively displayed.

3 is a flowchart illustrating a measurement process of the gas measuring device of FIG. 1. At this time, the gas measuring device 10 will be described as an example that is separately provided outside the air purifier (1).

The gas measurement device 10 may detect harmful gas through the detection unit 110. In this case, the sensing unit 110 may simultaneously detect a plurality of harmful gases through the plurality of gas sensors 111. For example, six gas sensors 111 may be provided in the sensing unit 110.

The first storage unit 140 may store reference values of each of the harmful gases detectable by the detection unit 110. Accordingly, when the detection unit 110 detects the harmful gas, it may be possible to determine whether the detected harmful gas is a value greater than or equal to a reference value or a value less than or equal to a reference value. In this case, the reference value of the harmful gas may be input differently according to the user. Specifically, all harmful gases may be different for each specific space or individual. For example, when there is a patient with a specific disease in a place where the air purifier 1 is used, the harmful gas that causes the specific disease may be more harmful to the user suffering from the disease than the user who does not have the disease. In this case, the reference value of the harmful gas causing a specific disease may be input low. Accordingly, harmful gases that are harmful to the user can be more effectively detected.

When the measured value of the harmful gas detected by the detection unit 110 exceeds the reference value, the guide 130 may guide the filter 210 corresponding to the harmful gas detected by the detection unit 110. Specifically, the matching unit 120 may match and store the filters 210 corresponding to each harmful gas. That is, the guide unit 130 may guide the harmful gas customized filter 210 detected through matching information stored in the matching unit 120.

When the corresponding filter 210 is guided through the guide unit 130, the first storage unit 140 may store accumulated concentration data of the harmful gas detected by the detection unit 110. Accordingly, as the detection unit 110 repeatedly detects the harmful gas, concentration data of the harmful gas may be accumulated and stored in the first storage unit 140.

When the detection unit 110 does not detect the harmful gas exceeding the reference value, the gas measurement device 10 may immediately terminate the measurement of the harmful gas.

As the gas measuring device 10 is separately provided outside the air purifier 1, the gas measuring device 10 can measure harmful gas regardless of the location. In addition, before the air purifier 1 is provided, since harmful gas can be detected only by the gas measuring device 10, it is possible to have an effect of knowing whether the air purifier 1 is required.

4 is a flow chart showing a measurement process of the air purifier of FIG. 2. At this time, the gas measuring device 10 will be described as an example that is provided in the air purifier.

The gas measurement device 10 may detect harmful gas through the detection unit 110. In this case, the sensing unit 110 may simultaneously detect a plurality of harmful gases through the plurality of gas sensors 111. For example, five gas sensors 111 may be provided in the sensing unit 110.

In addition, a plurality of filters 210 may be provided in the filter unit 20. At this time, the number of filters 210 provided in the filter unit 20 may be less than the number of gas sensors 111, for example, when five gas sensors 111 are provided, the filter 210 is 3 Dogs may be provided.

The first storage unit 140 may store reference values of each of the harmful gases detectable by the detection unit 110. Accordingly, when the detection unit 110 detects the harmful gas, it may be possible to determine whether the detected harmful gas is a value greater than or equal to a reference value or a value less than or equal to a reference value.

When the measured value of the harmful gas detected by the detection unit 110 exceeds the reference value, the guide 130 may guide the filter 210 corresponding to the harmful gas detected by the detection unit 110. In this case, the filter 210 guided by the guide unit 130 may or may not be provided in the filter unit 20. When the filter 210 guided by the guide unit 130 is not provided in the filter unit 20, the filter 210 provided in the filter unit 20 is not guided by the guide unit 130 It can be replaced with the filter 210 guided at (130). That is, the filter 210 required at the time of detecting the harmful gas can be easily replaced and used.

When the corresponding filter 210 is guided through the guide unit 130, the first storage unit 140 may store accumulated concentration data of the harmful gas detected by the detection unit 110. Accordingly, as the detection unit 110 repeatedly detects the harmful gas, concentration data of the harmful gas may be accumulated and stored in the first storage unit 140.

The remaining life of the filter 210 may be displayed on the display unit 50 according to the concentration data of the harmful gas stored in the first storage unit 140. Specifically, the second storage unit 30 in which the usable time of each filter 210 is stored is the residual of each filter 210 by subtracting the accumulated concentration data of the harmful gas transmitted from the first storage unit 140. Life can be known. That is, by using the accumulated concentration data of the detected harmful gas, the remaining life of the filter 210 corresponding to the undetected harmful gas can be maintained as it is.

When there is a filter 210 whose remaining life is less than or equal to the reference value among the filters 210, the display unit 50 may display the replacement time of the filter 210. Specifically, the display unit 50 may notify whether the filter 210 needs to be replaced through the display 510 or the speaker 520. That is, as the remaining life of the filter 210 is calculated through the accumulated concentration data of the detected harmful gas, it is possible to prevent the filter 210 from being replaced more than necessary, and thus, maintenance cost may be reduced. .

The gas measuring apparatus and the air purifier including the gas measuring apparatus and the air purifier including the same have been described as specific embodiments as described above as a specific embodiment, but this is only an example, and the present invention is not limited thereto, and the basis disclosed in this specification It should be construed as having the widest scope according to ideas.
