Description

Humidification air purifier and its control method {Apparatus for both humidification and air cleaning, and contolling method the same}

The present invention relates to a humidifying air purifier and a control method therefor.

An air purifier is understood as a device that inhales and purifies contaminated air and then exhausts the purified air. As an example, the air cleaner may include a blower for introducing external air into the air cleaner and a filter capable of filtering dust or bacteria in the air.

A humidifier is understood as a device that sucks in air, humidifies it, and discharges it to provide moisture to the air. Conventional humidifiers are divided into a vibrating humidifier that atomizes water from a diaphragm and discharges it into the air, and a natural evaporative humidifier that naturally evaporates from a humidifying filter. The natural evaporative humidifier rotates the disk using a driving force, and a disk-type humidifier in which water is naturally evaporated from the surface of the disk in the air, and a humidifying filter-type humidifier that is naturally evaporated by air flowing in a humidified medium soaked with water. Are distinguished.

In recent years, humidifying air purifiers have been developed that add a humidifying function to an air cleaner. Particularly, in a humidified air purifier, a technology in which a fan motor of a blower is automatically controlled according to an external environment, that is, changes in ambient temperature or illuminance, has been developed.

Prior art document Korean Patent Publication No. 10-2016-0077263 (July 04, 2016) discloses an air purifier and a control method thereof. Specifically, the prior art document discloses a technique for reducing the noise caused by the rotation of the blowing fan by turning on the lighting unit as the illuminance becomes dark and operating in the silent mode.

However, the air purifier disclosed in the prior art document has the following problems.

In the case of the conventional air purifier, the rotational speed of the fan motor may be reduced according to the change in illuminance, but the fan motor control is not performed considering various environmental factors such as humidity or air cleanliness, so that the humidity control is not accurately performed. there was.

1.Public number (public date): 10-2016-0077263 (July 4, 2016) 2. Name of invention: Air purifier and control method.

This embodiment is proposed to solve the above problems, and by operating a fan motor control in consideration of a number of environmental factors, it is an object to provide a humidifying air purifier and a control method that can quickly create a comfortable indoor environment Is done.

In addition, an object of the present invention is to provide a humidifying air purifier and a control method of the fan motor that can determine the rotation speed of the fan based on environmental factors of relatively worse conditions.

In addition, an object of the present invention is to provide a humidifying air purifier and a control method thereof that can be efficiently operated by adjusting the brightness of the lighting unit and the display, as well as the rotational speed of the fan motor in response to environmental changes (eg, illuminance).

The control method of the humidifying air purifier according to the present embodiment is characterized in that it detects the humidity of the air, the air cleanliness, and controls the humidifying filter motor and the fan motor based on the detected humidity and air cleanliness.

At this time, the rotational speed of the fan motor increases as the sensed humidity decreases, and increases as the sensed air cleanliness decreases, so that the humidity can be maintained at an appropriate level.

Also, a humidity level corresponding to the sensed humidity may be determined, and a cleanliness level corresponding to the sensed air cleanliness may be determined. And after comparing the humidity level and the cleanliness level, the rotation speed of the fan motor can be determined based on a factor having a relatively lower level among the humidity level and the cleanliness level. The indoor environment can be quickly created.

The humidifying filter motor is turned on when the detected humidity is less than a certain humidity, and turned off when the detected humidity is greater than a certain humidity, so that the humidity can be properly maintained.

In addition, the ambient illuminance of the humidifying air purifier is detected, and it may be determined whether the detected illuminance is less than a reference value.

At this time, when the sensed illuminance is less than the reference value, the rotational speed of the fan motor may be reduced to the first RPM. In addition, if the sensed illuminance changes to a reference value or more while the fan motor rotates at the first RPM, the rotational speed of the fan motor may be increased to a second RPM higher than the first RPM.

In addition, when the sensed illuminance is less than the reference value, the lighting unit may be operated, and the brightness of the display may be kept low as the first brightness.

And, while the lighting unit is operated and the brightness of the display is maintained at the first brightness, if the detected illuminance changes to a reference value or higher, the operation of the lighting unit is stopped and the second brightness is brighter than the first brightness. Can be maintained as.

According to this embodiment, since the rotational speed of the fan motor can be efficiently determined based on the humidity of the air and the cleanliness of the air, there is an advantage of quickly creating a comfortable indoor environment.

In addition, since a fan motor can be driven based on environmental factors in a relatively worse condition among a plurality of environmental factors, there is an advantage in that precise control of the fan motor is possible.

In addition, since the rotation speed of the fan motor as well as the brightness of the lighting unit and the display can be adjusted in response to changes in illuminance, power consumption is greatly reduced and ease of use is greatly improved.

For example, the control unit 500 may control to increase the rotational speed of the fan motor 530 when the sensed humidity and / or cleanliness level is low. Conversely, when the detected humidity and / or cleanliness level is high, the control unit 500 may control to reduce the rotational speed of the fan motor 530.

Hereinafter, a method for controlling a smart clean mode of the present invention will be described in more detail with reference to the drawings.

9 is a flow chart showing a detailed control method for the smart clean mode of the humidified air purifier according to an embodiment of the present invention.

Referring to FIG. 9, in step S21, the humidified air purifier 10 may receive a smart clean mode from a user.

For example, the display 510 may be provided with a number of buttons for selecting various modes such as a smart clean mode or a smart sleep mode, and a user may select a smart clean mode through a smart clean mode select button.

When the smart clean mode is selected, in step S22, the controller 500 detects the current humidity to determine the humidity level. Here, the humidity level may mean a humidity section indicated by the detected humidity. That is, a plurality of humidity levels divided into various humidity sections may exist in the humidity level.

According to an embodiment, the humidity level may include a first humidity level, a second humidity level, and a third humidity level.

The first humidity level may mean a case where the detected humidity is less than 45%. That is, when the sensed humidity corresponds to the first humidity level, it means that the indoor humidity is relatively low. At this time, the humidifying filter motor 520 is turned on, and the fan motor 530 can be rotated at a high speed. have. By high speed, it may mean about 400 RPM.

The second humidity level may mean a case where the detected humidity is 40% or more and less than 65%. That is, when the sensed humidity corresponds to the second humidity level, it means that the indoor humidity is in a comfortable state. At this time, the humidifying filter motor 520 may be turned on, and the fan motor 530 may be rotated at medium speed. have. By medium speed, it may mean about 320 RPM.

The third humidity level may mean a case where the detected humidity is 65% or more. That is, when the sensed humidity corresponds to the third humidity level, it means that the indoor humidity is relatively high. At this time, the humidifying filter motor 520 may be turned off, and the fan motor 530 may be rotated at a low speed. have. By low speed, it may mean about 250 RPM.

Next, in step S23, the controller 500 controls the humidifying filter motor 520 according to the determined humidity level.

Specifically, when the determined humidity level corresponds to the first humidity level or the second humidity level, the control unit 500 may control the humidification filter motor 520 to be turned on. Then, the humidification filter motor 520 may rotate the humidification filter 530 at a constant RPM. Therefore, the humidity in the room can be increased or kept constant.

In addition, when the determined humidity level corresponds to the third humidity level, the control unit 500 may control to turn off the humidifying filter motor 520. Then, the rotation of the humidifying filter 530 is stopped, so that the humidity in the room can be reduced.

That is, the controller 500 can maintain the indoor humidity in an optimal state by turning on / off the operation of the humidifying filter motor 520 according to the current humidity state.

Next, in step S24, the control unit 500 may detect the amount of dust in the air and the concentration of pollutants, and then in step S25, determine the cleanliness level according to the detected amount of dust and the concentration of pollutants.

As described above, the cleanliness level may increase as the level of cleanliness increases as the detected amount of dust and the concentration of contaminants decrease, and the level of cleanliness may decrease as the concentration of sensed dust and the concentration of contaminants increases. At this time, the cleanliness level may be divided into a plurality of cleanliness level sections.

According to an embodiment, the cleanliness level may include a first cleanliness level, a second cleanliness level, a third cleanliness level, and a fourth cleanliness level.

The first cleanliness level may mean a case in which the detected amount of dust or the concentration of contaminants is greater than or equal to the first reference value.

The second cleanliness level may refer to a case in which the detected amount of dust or the concentration of contaminants is less than the first reference value and is greater than or equal to the second reference value. At this time, the second reference value is defined as a value smaller than the first reference value.

The third cleanliness level may mean a case in which the detected amount of dust or the concentration of contaminants is less than the second reference value, and is greater than or equal to the third reference value. At this time, the third reference value is defined as a value smaller than the second reference value.

The fourth cleanliness level may mean a case in which the detected amount of dust or the concentration of contaminants is less than the third reference value.

In summary, the first cleanliness level may be understood to be the highest level of indoor air pollution, and the fourth cleanliness level may be understood to be the level with the lowest indoor air pollution. And, among the reference values, the first reference value may be the largest value and the fourth reference value may be the smallest value.

Next, in step S26, the controller 500 controls the fan motor 530 based on the determined humidity level and cleanliness level.

Specifically, as the cleanliness level is lowered, the control unit 500 may increase the rotational speed of the fan motor 530. Conversely, the higher the cleanliness level is, the control unit 500 may reduce the rotational speed of the fan motor 530.

For example, the control unit 500 may increase the rotational speed of the fan motor 530 when the humidity level corresponds to the first humidity level, and when the humidity level corresponds to the third humidity level, the fan The rotational speed of the motor 530 can be reduced.

In this embodiment, the rotational speed of the fan motor 530 according to the humidity level and cleanliness level may be tabulated and stored in the memory. For example, the rotational speed of the fan motor according to the humidity level and the cleanliness level may be determined as shown in Table 1 below.

division Humidity Less than 45%

Referring to [Table 1], it can be seen that when the humidity level corresponds to the first humidity level, the fan motor 530 is rotated at a high speed (eg, 400 RPM) regardless of the cleanliness level.

However, when the humidity level corresponds to the third humidity level, it can be seen that the rotation speed of the fan motor 530 changes according to the cleanliness level. That is, in a specific humidity level section, the rotation speed of the fan motor 530 may vary based on the cleanliness level.

Specifically, in the present invention, after comparing the humidity level and the cleanliness level, the rotation speed of the fan motor 530 is determined based on a factor having a relatively lower level among the humidity level and the cleanliness level after comparison. You can. That is, it is possible to adjust the rotational speed of the fan motor 530 on the basis of the environmental factors in a relatively worse condition among the plurality of environmental factors.

According to the configuration of the present invention, the rotational speed of the fan motor 530 may be adjusted in consideration of both the humidity level and the cleanliness level, as well as an environmental factor having a relatively lower level among the humidity level and the cleanliness level. Since the fan motor 530 can be controlled on the basis of, there is an effect that can quickly create an optimal indoor environment in accordance with environmental changes.

Meanwhile, in the present embodiment, after the humidifying filter motor 520 is first driven, the fan motor 530 may be driven. This is because the humidification filter motor 520 is first driven so that the humidification filter 330 is rotated so that humidification of air can be achieved. Therefore, in order to efficiently discharge humidified air, it is preferable that the humidifying filter motor 520 is driven first.

10 is a flow chart showing a control method for a smart sleep mode of a humidified air purifier according to an embodiment of the present invention.

Referring to FIG. 10, the control unit 500 may receive a command for a smart sleep mode from a user, and operate the humidified air purifier 10 in a smart sleep mode.

In detail, in step S31, the humidified air purifier 10 may receive a smart sleep mode from a user.

For example, the display 510 may be provided with a number of buttons for selecting various modes such as a smart clean mode or a smart sleep mode, and a user may select a smart sleep mode through a smart sleep mode selection button.

When the smart sleep mode is selected, in step S32, the controller 500 controls the humidifying filter motor 520 according to the humidity level.

Specifically, the control unit 500 determines the current humidity level through the humidity sensor 570, and determines whether the humidifying filter motor 520 operates according to the determined humidity level.

That is, when the current humidity level corresponds to the first humidity level or the second humidity level, the controller 500 turns on the humidifying filter motor 520, and when the current humidity level corresponds to the third humidity level, The humidifying filter motor 520 may be turned off.

Next, in step S33, the control unit 500 controls to detect the ambient light of the humidifying air cleaner 10. That is, the control unit 500 may check whether or not the user has turned off the room for sleeping through the illuminance sensor 560.

In step S34, the controller 500 determines whether the current illuminance is less than a reference value. That is, the control unit 500 determines whether or not the indoor light is off.

If the current illuminance is less than the reference value, in step S35, the control unit 500 turns on the lighting unit 540. That is, when the room is dark, the illumination unit 540 may be operated to gently reflect or diffuse light emitted from the illumination source. Therefore, even if the room is dark, since the lighting unit 540 can function as a mood lamp or a guide lamp, there is an effect of improving user convenience.

In addition, in step S36, the controller 500 may set the brightness of the display 510 to the first brightness. Here, the first brightness may mean a brightness that is lower than the brightness of the display 510 at normal times. That is, when the room becomes dark, the light intensity of the display 510 is lowered, thereby reducing power consumption.

In addition, in step S37, the control unit 500 may control the fan motor 530 to a first RPM. Here, the first RPM may mean a rotational speed lower than the rotational speed of the fan motor 530 at normal times. That is, when the room becomes dark, the rotational speed of the fan motor 530 decreases, thereby reducing noise caused by driving the fan motor 530 and reducing power consumption.

Next, in step S38, the control unit 500 determines whether or not the current illuminance exceeds the reference value. That is, the control unit 500 may check whether the user has turned on the room through the illuminance sensor 560.

As a result of the determination, when the current illuminance does not exceed the reference value, that is, when the indoor lighting is not performed, the controller 500 may repeatedly perform the steps S35 to S37.

If, in steps S34 and S38, when the current illuminance exceeds the reference value, that is, when the indoor lighting is made, in step S39, the control unit 500 turns off the lighting unit 540. That is, when the room becomes bright, since the lighting unit 540 does not need to be turned on, power consumption can be reduced by turning off the lighting unit 540.

In addition, in step S40, the controller 500 may set the brightness of the display 510 to the second brightness. Here, the second brightness may mean the brightness of the display 510 during normal use. The second brightness may have a brightness that is brighter than the first brightness. Therefore, the information displayed on the display 510 can be easily recognized even in a bright indoor environment.

In addition, in step S41, the control unit 500 may control the fan motor 530 to a second RPM. Here, the second RPM may mean the rotational speed of the fan motor 530 at normal times. The second RPM may be greater than the first RPM. Therefore, when the room becomes bright, the control unit 500 may increase the rotational speed of the blowing fan 480, thereby improving air filtering and humidifying performance.

Meanwhile, in the present embodiment, steps S35, S36, and S37 have been described as being sequentially performed, but are not limited thereto. For example, the operations of steps S35, S36, and S37 may be performed simultaneously, and may be sequentially performed in an ordered state.

Likewise, the operations of steps S39, S40, and S41 may be performed simultaneously, and of course, they may be performed sequentially with the order reversed.

According to the configuration of the present invention, since the lighting unit, the display and the fan motor of the humidifying air purifier can be controlled in consideration of the user's sleeping state, power consumption is reduced and ease of use can be improved.
