Description

AIR CLEANER CALCULATING INFORMATION FOR ITS USED SPACE}

The present invention relates to an air purifier that obtains information on used space, and more particularly, automatically obtains information on the area or volume of an indoor space in which the air purifier is used, and informs the user or operates the air purifier according to the obtained information. It relates to an air purifier that obtains space information that can be automatically controlled.

Recently, for reasons of air pollution and building energy efficiency improvement, the indoors are increasingly blocked from the outside environment.If contaminated air generated indoors continues to circulate indoors without exchanging with outside air, it is fatal to people who engage in indoor activities for a long time. It can lead to disease outbreaks.

Accordingly, the use of air purifiers to reduce indoor pollution is increasing rapidly in a situation in which external discharge of indoor pollutants is limited because it is blocked from the external environment.

In general, an air purifier is an air purifier that filters contaminants and fine dust in the air sucked through an intake port in the process of forcibly circulating indoor air by blowing, and discharges only clean air to the discharge port.

These air purifiers can be divided into small, medium, and large, depending on their cleaning ability. Before the product is released, the air purifier's performance test, which is a cleaning ability test, is performed, and the rated area is marked and released.

Although each air purifier has a rated exclusive area, users can use an air purifier in a space much larger than the rated exclusive area to reduce air cleaning efficiency, or use an air purifier in a space much smaller than the rated exclusive area. It is also wasting power by running air purifiers with high power. In addition, even when the air purifier is used in a space similar to the rated exclusive area, the actual size of the space in which the air purifier operates may have a big difference from what users think due to items placed in the indoor space such as furniture. do.

Advantages and features of the present invention, and a method of achieving them will become apparent with reference to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms, and only these embodiments make the disclosure of the present invention complete, and are common knowledge in the technical field to which the present invention pertains. It is provided to completely inform the scope of the invention to those who have, and the invention is only defined by the scope of the claims. The same reference numerals refer to the same elements throughout the specification.

Hereinafter, the present invention will be described with reference to drawings for explaining an air purifier for obtaining space information according to embodiments of the present invention.

The air purifier for obtaining used space information according to an embodiment of the present invention may include a dust sensor and a used space information calculating unit. In addition, a notification unit and a control unit may be further included.

The dust sensor is mounted on the air purifier and measures the concentration of dust in the space where the air purifier is located. At this time, the dust sensor is a sensing method such as an optical dust sensor that measures the dust concentration by irradiating light and receiving the light scattered by the particles, and a resistive dust sensor measuring the dust concentration by detecting the change in resistance between electrodes by particles. It is not limited to, and all types of known dust sensors can be used.

In addition, as will be described later with reference to the drawings, the air purifier according to an embodiment of the present invention may be an electric dust collection type air purifier, but is not limited thereto, and is applied to and used in filter type air purifiers and other types of air purifiers. There can be.

The used space information calculation unit calculates information on the area or volume of the space where the air purifier is actually used by using the dust concentration value measured by the dust sensor.

Before the air purifier is released as a product, it conducts the purifying ability test, which is the performance test of the air purifier, and accordingly, the purifying capacity index or the rated exclusive area is marked and sold. At this time, the cleaning ability is calculated by the following equation (1),

In this case, the rated application area is defined as the area of the room that can reduce the indoor particle concentration to 50% of the initial particle concentration by operating the air purifier for 10 minutes according to the air purifier standard. At this time, the height of the indoor ceiling is calculated based on 2.4m, and when applied to the above formula for cleaning capacity, the rated exclusive area (

It can be obtained by consciousness.

In the same way as described above, through the cleaning ability test, the cleaning ability index or rated exclusive area indicating the cleaning performance of the product can be obtained.

In this way, the used space information calculation unit operates the actual air purifier with the rated exclusive area value or the purification capacity index value obtained in advance through the purification ability test before the air purifier is released, and operates the air purifier at a predetermined time interval (

), the value of the dust concentration measured by the dust sensor (

,

By substituting) into Equation 1, information on the volume or area of the space in which the air purifier is actually used can be calculated.

The notification unit notifies the user of a visual or an audible signal of information about the space in which the air purifier is actually used, obtained by the used space information calculation unit. For example, by forming a display device on the main body of the air purifier, the area or volume of the space in which the air purifier is actually used is displayed, or compared with the rated exclusive area, and information about this can be visually transmitted to the user. In addition, this information may be transmitted to the user aurally through a method such as a voice message or an alarm.

The control unit automatically controls the cleaning operation of the air purifier according to the information on the volume or area of the space in which the air purifier is actually used obtained by the used space information calculation unit. For example, it is possible to automatically control the cleaning operation of the air purifier by comparing the value of the rated exclusive area of the air purifier and the area of the space in which the air purifier obtained by the space information calculation unit is actually used.

More specifically, if the value of the area calculated by the space information calculation unit is larger than the value of the rated exclusive area of the air purifier, increase the rotation speed of the fan that flows air inside the air purifier or the air purifier of the electric dust collection method. By controlling to increase the level of the voltage applied to the dust collecting unit, it can be controlled to increase the air cleaning power of the air purifier. Since it is actually used in a larger area than the rated exclusive area of the air purifier, the air purifier of the air purifier is operated by increasing the air purifying power so that the indoor air can be purified in a short time. However, if the value of the area calculated by the use space information calculation task is relatively too large compared to the rated exclusive area value, even if the air purifier is operated by increasing the air cleaning power in the above manner, there will be a limit to purifying the indoor air. Therefore, in this case, it would be desirable to notify the user that the air purifier is currently disposed in an appropriate space and is not being used through the notification unit.

On the contrary, if the value of the area calculated by the space information calculation unit is smaller than the value of the rated exclusive area of the air purifier, control to lower the rotation speed of the fan or the voltage applied to the dust collecting unit to reduce the air purifying power of the air purifier. It can be controlled to slightly lower the power consumption but reduce unnecessary power waste.

Hereinafter, a configuration of an air purifier that obtains space information according to an embodiment of the present invention will be described in more detail.

1 is a perspective view of an air purifier according to an embodiment of the present invention, FIG. 2 is a perspective view showing the interior in FIG. 1, FIG. 3 is a perspective view showing a modified example of a dust collecting unit in FIG. 2, and FIG. 4 is It is a side cross-sectional view of FIG. 3.

The housing 100 serves as the main frame of the air purifier, and internally accommodates or mounts constituent parts such as an ion generating unit 110, a dust collecting unit 120, a fan 130, and a dust sensor 140 to be described later. Provide a space to do. In addition, an operation button 105 for controlling power, air volume, operation mode, etc. of the air purifier may be formed on one side of the housing 100, and a display device 106 for outputting information provided by the air purifier to the user is provided. Can be formed. In addition, an inlet 104 for introducing contaminated air may be formed in the lower part of the housing 100, and a discharge port 102 for discharging purified air may be formed along the circumference of the upper side of the housing 100. have.

The ion generating unit 110 generates ions that charge particulate matter such as dust to have polarity. At this time, the ion generating unit 110 is formed of a microfiber discharge electrode 110, generates positive ions or negative ions by high voltage, and discharges them to the outside of the housing 100. Accordingly, dust particles in the indoor space outside the housing 100 may be charged to the cathode or the anode by ions generated in the ion generating unit 110. The microfiber discharge electrode 110 may be made of a microfiber made of a carbon fiber or a SUS material, and according to this configuration, there is an advantage in that a high concentration of ions may be generated when a fixation eye is applied to the electrode and ozone is not generated.

In this case, the discharge electrode 110 constituting the ion generating unit 110 and generating ions is preferably formed to protrude outside the housing 100 as shown in FIG. 1. When the discharge electrode 110 is formed inside the housing 100 and is discharged through a predetermined discharge port, it is confirmed by experiment that ions are destroyed inside the housing 100 and a large amount of ions are not discharged into the atmosphere of the indoor space. Therefore, as in the present embodiment, the discharge electrode 120 protrudes out of the housing 100 so that a large amount of ions are spread out, so that dust particles in the atmosphere of the indoor space can be charged more efficiently. have. In the drawing, the ion generating unit 110 is formed only on one side of the housing 100, but the present invention is not limited thereto, and for example, the ion generating unit 110 is additionally provided on the other side along the circumference of the housing 110. Can be formed.

The fan 130 forms a flow of air inside and outside the housing 100. As shown in FIG. 1, it is formed in the upper portion of the housing 100 to introduce air in the indoor space through the inlet 104 under the housing 100, and formed in the housing 100 through the dust collecting unit 120. A flow of air discharged through the discharge port 102 is formed. Accordingly, the ions radiated into the atmosphere of the indoor space by the ion generator 110 charge the particles of the indoor space, and the charged particles flow into the housing 100 by the flow of air formed by the fan 130 It is purified through the filter 150 and the dust collecting unit 120, and the purified air may be discharged through the discharge port 102.

In the interior of the housing 100, a filter 150 for filtering dust having a relatively large particle size or a functional filter 150 for removing odor may be installed, and the upper portion of the filter 150 is charged by ions. A dust collecting part 120 is formed to collect the collected particles by electric force.

The dust collecting unit 120 is formed in a plate shape and generates a potential difference between the first electrode 121 and the second electrode 122 having different polarities, so that the positive or negatively charged particles are converted into an electrode having the opposite polarity. It is guided by the force of and collected. In the present invention, the plurality of first electrodes 121 and the second electrodes 122 are formed so as to be repeated with each other in parallel with the movement path of the charged particles, thereby further increasing the dust collection efficiency.

As described above, the used space information calculation unit (not shown) uses the value of the rated exclusive area or the purification capability index of the air purifier and the dust concentration value measured by the dust sensor 140 for a predetermined time interval. Calculate information about the area or volume of the space actually used. Since a detailed description of this has been described above, it will be omitted.

The control unit (not shown) controls the operation of the air purifier.In particular, in the present invention, information on the area or volume of the space in which the air purifier determined by the calculation unit is actually used, as described above, By comparison, the rotation speed of the fan 130 or the magnitude of the voltage applied to the dust collecting unit 120 can be automatically controlled.

3 and 4 show a modified example of the above-described dust collecting unit 120, in which a plurality of plate-shaped first electrodes 121 and second electrodes 122 are arranged to repeat each other. A plurality of the first electrode 121 and the second electrode 122 are repeated in the same shape as the first dust collecting part 120a in a space adjacent to the first dust collecting part 120a along the flow direction of 120a and air. It may be composed of the disposed second dust collecting unit 120b. In this case, the widths of the gaps between the first electrode 121 and the second electrode 122 in the first dust collecting unit 120a and the second dust collecting unit 120b may be different from each other. That is, as shown in FIGS. 3 and 4, the distance between the two electrodes 121 and 122 in the first dust collecting unit 120a positioned at the bottom is between the two electrodes 121 and 122 in the second dust collecting unit 120b. Compared to the gap of the gap, the size of the gap can be formed larger.

The magnitude of the electric field between the two electrodes 121 and 122 with different polarities is proportional to the magnitude of the voltage and inversely proportional to the distance between the two electrodes 121 and 122. Therefore, if the distance between the two electrodes 121 and 122 is narrow, The narrower it is, the better the dust collecting power.

In the present invention, the controller (not shown) compares the value of the rated exclusive area of the air purifier with the information on the area or volume of the space in which the air purifier is actually used, which is obtained by the space information calculation unit. The rotation speed or the voltage applied to the dust collecting unit 120 may be controlled to vary.

In addition, the control unit may control on/off of a voltage applied to the first dust collecting unit 120a or the second dust collecting unit 120b. For example, if the area of the space in which the air purifier is actually used is large, compared with the value of the rated exclusive area of the air purifier and calculated by the space information calculator Is turned on and the power applied to the first dust collecting unit 120a is turned off, or both the power applied to the first dust collecting unit 120a and the second dust collecting unit 120b are turned on to collect the charged particles. You can increase it. Conversely, when the area of the space actually used by the air purifier obtained by the used space information calculation unit compared to the rated exclusive area value of the air purifier is small, the control unit is configured to have a relatively weak dust collecting power compared to the second dust collecting unit 120b. 1 The control unit can automatically control the operation of the air purifier to consume and minimize power by turning on the power applied to the dust collecting unit 120a and turning off the power applied to the second dust collecting unit 120b. . For reference, FIG. 4 shows a state in which charged particles are collected in the first dust collecting part 120a by applying power only to the first dust collecting part 120a.

The scope of the present invention is not limited to the above-described embodiments, but may be implemented in various forms within the scope of the appended claims. Without departing from the gist of the present invention claimed in the claims, any person of ordinary skill in the art to which the present invention belongs is considered to be within the scope of the description of the claims of the present invention to various ranges that can be modified.
