That is, the second blower fan (123) can increase or decrease the rotation speed so that the shower air with the controlled amount of outdoor air is sprayed from the second discharge port (122).

Fig. 3 is a control block diagram showing the control configuration of an air wash device according to the first embodiment.

Figure 3 briefly describes the configuration described in Figures 1 and 2, or the description thereof is omitted.

Referring to FIG. 3, the air wash device (100) may include first and second air modules (210, 220), a sensor module (230), and a control module (240).

The first air module (210) can drive the first injection device (110) described in FIGS. 1 and 2.

That is, the first air module (210) can inject curtain air (ar) from the first injection device (110) under the control of the control module (240) to distinguish between the indoor space (S1) and the entrance space (S2).

Here, the curtain air (ar) can be sprayed in a vertical direction, i.e., from the top to the bottom of the entrance, and the air volume of the curtain air (ar) can be varied to correspond to the air volume of the shower air (war) sprayed from the second air module (220), but is not limited thereto.

The first air module (210) may be turned on and operated at the same time as the second air module (220) under the control of the control module (240) to spray air (ar) for the curtain, or may be turned on and operated at a time before the turning on time of the second air module (220) to spray air (ar) for the curtain, but is not limited thereto.

In addition, the first air module (210) may be turned off at the same time as the second air module (220) under the control of the control module (240) to block the air (ar) for the curtain being sprayed, or may be turned off at a time later than the turning off time of the second air module (220) to block the air (ar) for the curtain being sprayed, but is not limited thereto.

The second air module (220) can spray shower air (war) from the second spray device (120) into the entrance space (S2) under the control of the control module (240).

Here, the second air module (220) can be turned on and sprayed with shower air (war) at a time point after the turn-on operation time of the first air module (210), or can be turned on and sprayed with shower air (war) at the turn-on operation time of the first air module (210).

At this time, the shower air (war) can be sprayed in a vertical direction from the top of the entrance to the bottom, or in a diagonal direction from the top of the entrance to the side, and if the second spray device (120) is installed on the side of the entrance, it can be sprayed in the side direction, but is not limited thereto.

The sensor module (230) may include first to third sensor units (232 to 236).

The first sensor unit (232) can output a first signal (as1) of high level when the front door (10) changes from a closed state to an open state.

Here, the first sensor unit (232) may include at least one of a proximity sensor that detects the open state of the front door (10) and outputs a first signal (as1) of a high level and a first signal (as1) of a low level by detecting the closed state, and a light sensor that outputs a first signal (as1) in response to a change in the amount of light when the front door (10) is changed from a closed state to an open state. In the embodiment, the first sensor unit (232) is described as including a proximity sensor.

That is, the first sensor unit (232) can be installed on either the front door (10) or the doorpost (20), and when including the proximity sensor, it can output a first signal (as1) of high level or low level depending on whether the side of the front door (10) and the side of the doorpost (20) are detected with each other.

The second sensor unit (234) can output a second signal (as2) corresponding to the height of a person located in the entrance space (S2).

That is, the second sensor unit (234) may include an infrared sensor that transmits an infrared signal to measure a person's height and outputs a received second signal (as2), but is not limited thereto.

The third sensor unit (236) may include a dust sensor capable of measuring the amount of dust (as3) in the entrance space (S2).

The control module (240) may include a condition judgment unit (242), a calculation unit (244), and a control unit (246).

The condition judgment unit (242) can determine whether the injection condition for determining whether the second air module (220) is turned on is satisfied after the first signal (as1) corresponding to the open state of the front door (10) is input from the first sensor unit (232), the first air module (210) operates, and air (ar) for curtains is sprayed.

The above injection condition may be a time condition for the front door (10) to be maintained in the open state, and the condition judgment unit (252) may determine that the injection condition is satisfied if the maintenance time of the first signal (as1) for the front door (10) to be maintained in the open state, i.e., the time for which the same level value is maintained from the input time, exceeds the standard maintenance time set in the above injection condition.

When a high-level first signal (as1) is input from the first sensor unit (232), the control unit (246) confirms that the front door (10) is open, and operates in an air blocking mode to distinguish between the indoor space (S1) and the front door space (S2), thereby controlling the first air module (210) to spray curtain air (ar).

Here, the control unit (246) can control the curtain air (ar) to the first blocking air volume when the air blocking mode is in operation, and prevent outdoor air from flowing into the indoor space (S1) when the front door (10) is open.

At this time, when a second signal (as2) is input from the second sensor unit (244) during the air blocking mode operation, the output unit (244) can calculate the height of a person based on the second signal (as2).

The control unit (246) switches the air blocking mode to the dust blocking mode when the second signal (as2) is input, and can increase the curtain air (ar) from the first blocking air volume to the second blocking air volume.

Thereafter, the control unit (246) can control the second air module (220) to spray shower air (war) at a preset wind speed corresponding to the height of the person calculated by the calculation unit (244).

For example, assuming that the height of a person is 1 meter 80 centimeters, the control unit (246) can control the shower air (war) to be sprayed at a set wind speed corresponding to 1 meter 80 centimeters, i.e. 100, within the preset lookup table when the height of the person calculated by the calculation unit (244), i.e. 1 meter 80 centimeters, is 100.

However, assuming that the height of the person is 1 meter 10 centimeters for an infant, the control unit (246) can control the shower air (war) to be sprayed at a set air volume corresponding to 1 meter 10 centimeters, i.e. 130, within the preset lookup table when the height of the person calculated by the calculation unit (244), i.e. 1 meter 10 centimeters, is 130.

As described above, the control unit (246) can increase the air volume of the shower air (war) when the user is an infant compared to the air volume of the shower air (war) when the user is an adult.

In addition, the control unit (246) can vary the spraying time of shower air (war) depending on the presence or location of a person when an infrared sensor capable of detecting a person or an image sensor capable of capturing an image of a person is included in the sensor module (230), but is not limited thereto.

The control unit (246) can control the second air module (220) to stop spraying the shower air (war) when the spraying duration of the shower air (war) exceeds the set standard spraying time while operating in the dust blocking mode.

And, when the control unit (246) stops spraying the shower air (war), it can control the dust blocking mode to be switched to the air blocking mode so that the spraying of the curtain air (ar1) stops after a predetermined time has elapsed.

Meanwhile, the control unit (246) can control the spraying of the shower air (war) to be stopped when the dust amount (as3) is input from the third sensor unit (236) after the shower air (war) is sprayed during the dust blocking mode operation and the dust amount (as3) decreases to a set standard dust amount.

At this time, when the spraying of shower air (war) is stopped according to the amount of dust (as3), the control unit (246) can stop the spraying of shower air (war) even if the spraying duration of the shower air (war) does not exceed the above-mentioned standard spraying time.

In this way, the air wash device according to the embodiment has the advantage of being able to easily remove dust regardless of whether the person is an adult or an infant by spraying shower air at a set air volume corresponding to the height of a person located in the entrance space.

Fig. 4 is a control block diagram showing the control configuration of an air wash device according to the second embodiment.

Referring to FIG. 4, the air wash device (100) may include first and second air modules (310, 320), a sensor module (330), a communication module (340), and a control module (350).

The first air module (310) can drive the first injection device (110) described in FIGS. 1 and 2.

That is, the first air module (310) can inject curtain air (ar) from the first injection device (110) under the control of the control module (350) to distinguish between the indoor space (S1) and the entrance space (S2).

Here, the curtain air (ar) can be sprayed in a vertical direction, i.e., from the top to the bottom of the entrance, and the air volume of the curtain air (ar) can be varied to correspond to the air volume of the shower air (war) sprayed from the second air module (320), but is not limited thereto.

The first air module (310) may be turned on and operated at the same time as the second air module (320) under the control of the control module (350) to spray air (ar) for the curtain, or may be turned on and operated at a time before the turning on time of the second air module (320) to spray air (ar) for the curtain, but is not limited thereto.

In addition, the first air module (310) may be turned off at the same time as the second air module (320) under the control of the control module (350) to block the air (ar) for the curtain being sprayed, or may be turned off at a time later than the turning off time of the second air module (320) to block the air (ar) for the curtain being sprayed, but is not limited thereto.

The second air module (320) can spray shower air (war) from the second spray device (120) into the entrance space (S2) under the control of the control module (350).

Here, the second air module (320) may be turned on at a time point after the on-operation time of the first air module (310) to spray shower air (war), or may be turned on at the on-operation time of the first air module (310) to spray shower air (war).

At this time, the shower air (war) can be sprayed in a vertical direction from the top of the entrance to the bottom, or in a diagonal direction from the top of the entrance to the side, and if the second spray device (120) is installed on the side of the entrance, it can be sprayed in the side direction, but is not limited thereto.

The sensor module (330) may include first to third sensor units (332 to 336).

The first sensor unit (332) can output a first signal (as1) of high level when the front door (10) changes from a closed state to an open state.

Here, the first sensor unit (332) may include at least one of a proximity sensor that detects the open state of the front door (10) and outputs a first signal (as1) of a high level and a first signal (as1) of a low level by detecting the closed state, and a light sensor that outputs a first signal (as1) in response to a change in the amount of light when the front door (10) is changed from a closed state to an open state. In the embodiment, the first sensor unit (332) is described as including a proximity sensor.

That is, the first sensor unit (332) can be installed on either the front door (10) or the doorpost (20), and when including the proximity sensor, it can output a first signal (as1) of high level or low level depending on whether the side of the front door (10) and the side of the doorpost (20) are detected with each other.

The second sensor unit (334) can output a second signal (as2) corresponding to the height of a person located in the entrance space (S2).

That is, the second sensor unit (334) may include an infrared sensor that transmits an infrared signal to measure a person's height and outputs a received second signal (as2), but is not limited thereto.

The third sensor unit (336) may include a dust sensor capable of measuring the amount of dust (as3) in the entrance space (S2).

The communication module (340) can receive weather information (ws) transmitted from an external server (SV).

Here, the communication module (340) can receive weather information (ws) through wired or wireless communication with an external server (SV), and can be an IoT sensor capable of measuring indoor air pollution levels and outdoor air pollution levels, but is not limited thereto.

In the embodiment, the communication module (340) is described as a module device capable of communicating with an external server (SV), but may be an IoT device or an IoT sensor, and is not limited thereto.

The control module (350) may include a condition judgment unit (352), a calculation unit (354), a decision unit (356), and a control unit (358).

The condition judgment unit (352) can determine whether the injection condition for determining whether the second air module (320) is turned on is satisfied after the first signal (as1) corresponding to the open state of the front door (10) is input from the first sensor unit (332), the first air module (310) operates, and air (ar) for curtains is sprayed.

The above injection condition may be a time condition for the front door (10) to be maintained in the open state, and the condition judgment unit (252) may determine that the injection condition is satisfied if the maintenance time of the first signal (as1) for the front door (10) to be maintained in the open state, i.e., the time for which the same level value is maintained from the input time, exceeds the standard maintenance time set in the above injection condition.

When a high-level first signal (as1) is input from the first sensor unit (332), the control unit (358) confirms that the front door (10) is open, and operates in an air blocking mode to distinguish between the indoor space (S1) and the front door space (S2), thereby controlling the first air module (310) to spray curtain air (ar).

Here, the control unit (358) can control the curtain air (ar) to the first blocking air volume when the air blocking mode is in operation, and prevent outdoor air from flowing into the indoor space (S1) when the front door (10) is open.

At this time, when a second signal (as2) is input from the second sensor unit (354) during the air blocking mode operation, the output unit (354) can calculate the height of a person based on the second signal (as2).

The control unit (358) switches the air blocking mode to the dust blocking mode when the second signal (as2) is input, and can increase the curtain air (ar) from the first blocking air volume to the second blocking air volume.

Here, the decision unit (356) can determine the spray temperature and spray conditions of shower air (war) according to the weather information (ws) input from the communication module (340).

That is, weather information (ws) may include at least one of temperature and humidity, but is not limited thereto.

For example, if the weather information (ws) includes information that the current temperature is -1 degree Celsius and the humidity is 80%, the decision unit (356) may determine that the clothes of a person located in the entrance space (S2) are wet with rain or snow, and may determine the spray temperature of the shower air (war) to be higher than the standard spray temperature, the wind speed to be higher than the standard wind speed, and the spray time of the shower air (war) to be longer than the standard spray time so that foreign substances attached to the clothes of the person can be easily shaken off.

Thereafter, the control unit (358) can control the second air module (320) to spray shower air (war) at a preset wind speed corresponding to the height of the person produced by the production unit (354) and the spray temperature and spray time of the shower air (war) determined by the decision unit (356).

For example, assuming that the height of a person is 1 meter 80 centimeters for an adult, the control unit (358) can control the shower air (war) to be sprayed at the spray time and the spray temperature at the set wind speed corresponding to 1 meter 80 centimeters, i.e. 100, within the preset lookup table when the height of the person calculated by the calculation unit (354), i.e. 1 meter 80 centimeters, is calculated.

However, assuming that the height of the person is 1 meter 10 centimeters for an infant, the control unit (358) can control the shower air (war) to be sprayed at the spray time and temperature described above at the set wind speed corresponding to 1 meter 10 centimeters, that is, 130, within the preset lookup table when the height of the person calculated by the calculation unit (354), that is, 1 meter 10 centimeters, is calculated.

As described above, the control unit (358) can increase the air volume of the shower air (war) when the user is an infant compared to the air volume of the shower air (war) when the user is an adult.

In addition, the control unit (358) can vary the spraying time of shower air (war) depending on the presence or location of a person when an infrared sensor capable of detecting a person or an image sensor capable of capturing an image of a person is included in the sensor module (330), but is not limited thereto.

The control unit (358) can control the second air module (320) to stop spraying the shower air (war) when the shower air (war) is sprayed during the spraying time while operating in the dust blocking mode.

And, when the control unit (358) stops spraying the shower air (war), it can control the dust blocking mode to be switched to the air blocking mode so that the spraying of the curtain air (ar1) stops after a predetermined time has elapsed.

Meanwhile, when the control unit (358) receives the dust amount (as3) from the third sensor unit (336) after the shower air (war) is sprayed during the dust blocking mode operation, and the dust amount (as3) decreases to a set standard dust amount, the control unit can control the spraying to stop even if the shower air (war) does not satisfy the spraying time.

In this way, the air wash device according to the embodiment has the advantage of being able to easily remove dust regardless of whether the person is an adult or an infant and the current state of clothing by changing the spray temperature and spray time of shower air according to the height and weather conditions of the person located in the entrance space and then spraying shower air at a set wind speed.
