The present invention relates to an air purifier.

Background Art Conventionally, an air purifier has been widely used as an apparatus for purifying air by trapping dust and the like suspended in air. An air purifier is usually provided with a motor, a fan, and a filter, and a fan is rotated by a motor to inhale air inside, and the suctioned air is passed through a filter to capture dust and the like with a filter to purify the air. Such an air purifier is described in document 1.

The air purifier includes a dust collecting filter and a deodorizing filter, and dust and odor contained in the air are removed by passing the air through these filters.

However, in the air purifier described in Document 1, since the dust collecting filter and the deodorizing filter are arranged so as to overlap in the thickness direction of the air purifier, the depth of the air purifier is increased and the installation area becomes large (a large installation place is required). There is a problem.

In addition, in order to improve the performance of the air cleaner, it is possible to increase the size of the fan and the filter, but in this case as well, there is a problem such as an increase in the installation area of the air cleaner.

In addition, another object of the present invention is to provide an air cleaner that can purify air efficiently.

In order to achieve the above object, the present invention provides an air purifier in which a fan is rotated by a motor to suck in air, and the sucked air is purified by passing through a filter and exhausted from the exhaust port. Each of the constituent units including the two upper and lower stages are arranged, and the inlet and exhaust ports for the upper constituent unit and the inlet and exhaust ports for the lower constituent unit are respectively distributed up and down, the gas concentration in the air It has a gas sensor which detects and a moving object detection sensor which detects the object moving in a room, and controls the motor of the said up-and-down structural unit separately according to the detection output of a gas sensor and a moving object detection sensor.

For example, the motor of the upper component unit is driven by the detection signal of the gas sensor, and the motor of the lower component unit is driven by the detection signal of the moving object sensor.

Alternatively, the motor of the upper component unit is driven more centrally than the motor of the lower component unit by the detection signal of the gas sensor, and the motor of the lower component unit is driven more centrally than the motor of the upper component unit by the detection signal of the moving object sensor. do. Specifically, the motor of the upper component unit is driven faster than the motor of the lower component unit by the detection signal of the gas sensor, and the motor of the lower component unit is faster than the motor of the upper component unit by the detection signal of the moving object sensor. To drive.

Moreover, the detection output level by a gas sensor and the detection output level by a moving object sensor are compared, and the motor of an up-and-down structural unit is controlled based on the larger detection output level.

Examples of the moving object detecting sensor include detecting the movement of a person by a pyroelectric infrared sensor.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail with reference to an accompanying drawing. 1 is a front view showing the configuration of an air cleaner 1 according to an embodiment of the present invention. 2 is a figure which shows the state which cut | disconnected the air cleaner 1 shown in FIG. 1 by the cutting line A-A.

The air purifier 1 is installed indoors, for example, to take in air outside the device, to clean the air, and to discharge the air out of the device, thereby to clean the air in the room. The external shape of the air cleaner 1 is partitioned by the thin housing 2 whose length of the front-back direction is short compared with the length of the left-right direction. The front face of the housing 2 has an approximately rectangular upper front face plate 3 covering approximately the upper half of the front face of the housing 2 and a substantially rectangular lower front covering the lower half of the front face of the housing 2. The face plate 4 is attached. Moreover, the operation panel 5 as an operation display part is attached between the front faceplate 3 and the lower front faceplate 4 of the front face of the housing | casing 2. Moreover, the upper exhaust port 6 is formed in the right side of the upper part of the housing 2 when seen from the front side, and the lower exhaust port 7 is formed in the left side of the lower part of the housing 2 as seen from the front side.

The upper front face plate 3 is provided with a plurality of elongated upper inlet ports 8 extending from the top to the bottom of the upper front face plate 3. In addition, a gas sensor 10 and a moving object detecting sensor 11 are provided inside the upper front plate 3.

The gas sensor 10 is formed of a metal oxide semiconductor and is well known for detecting a reducing gas generated by smoking or the like. The moving object detecting sensor 11 is called a pyroelectric infrared sensor. The moving object detecting sensor 11 receives far-infrared rays emitted from the surface of the human body and the wearer's body, and a person moves to generate a pyroelectric effect on the pyroelectric infrared sensor to detect a person's movement. will be.

The lower front face plate 4 is provided with a plurality of elongated lower inlet ports 9 extending from the top to the bottom of the lower front face plate 4.

The upper exhaust port 6 is for purifying the air sucked from the upper inlet 8 as described later, and then exhausting the air. The air sucked from the upper inlet 8 is swirled by broken lines in FIG. The upper fan casing 40 of the shape is moved and exhausted from the upper exhaust port 6. The lower exhaust port 7 is for purifying the air sucked from the lower intake port 9 as described later, and then evacuating the air. The air sucked from the lower intake port 9 is vortex indicated by broken lines in FIG. It moves in the lower fan casing 50 of a shape, and is exhausted from the lower exhaust port 7.

The housing 2 is formed with an upper compartment 12 partitioned to occupy approximately the upper half of the housing 2 and a lower compartment 13 partitioned to occupy approximately the lower half of the housing 2. The upper partition 12 is partitioned by the upper front face plate 3 in the front side. In addition, the upper compartment 12 is provided with a fine dust filter 14 and a deodorizing filter 15 behind a predetermined dimension of the upper front face plate 3.

The fine dust filter 14 is a size that can cover the upper intake port 8 formed in the upper front plate 3, and is composed of a high-performance filter capable of capturing fine dust. The deodorization filter 15 is about the same size as the fine dust filter 14, and is comprised with the activated carbon which can adsorb a bad smell, and the filter which can capture gas components. And the deodorizing filter 15 is arrange | positioned so that it may overlap in the thickness direction of the fine dust filter 14 and the housing 2.

In addition, the upper partition chamber 12 is provided with a partition member 15 constituting a part of the upper fan casing 40, and the upper motor 17 is attached to the partition member 16. In addition, a fan 18 is attached to the rotary shaft 17a of the upper motor 17.

The fan 18 is a so-called sirocco fan, and when the fan 18 is rotated, air is sucked from the front center side so that the air is discharged in the radial direction of the fan 18. Therefore, when the fan 18 is rotated, as shown by arrow B in FIG. 2, air outside the device is sucked from the upper intake port 8 and passes through the fine dust filter 14 and the deodorization filter 15, and the fan 18 ) In the radial direction. In addition, the upper fan casing 40 is connected to the upper exhaust port 6 so that air flowing in the radial direction of the fan 18 is exhausted out of the apparatus from the upper exhaust port 6 as indicated by arrow C in FIG.

In this manner, the upper constituent unit 25 including the upper motor 17, the fan 18, the fine dust filter 14, and the deodorizing filter 15 is provided at the upper end in the housing 2.

The lower partition chamber 13 is partitioned by the lower front face plate 4 in the front side. In addition, the lower partition chamber 13 is provided with a coarse dust filter 19 and a pollen-only filter 20 behind a predetermined dimension of the lower front face plate 4.

The coarse dust filter 19 is a size which can cover the lower inlet 9 formed in the lower front face plate 4, and is composed of a filter capable of capturing large dust. In other words, the coarse dust filter 19 is a filter having a larger gap than the fine dust filter 14, and the fine dust filter 14 is a high performance filter, and the coarse dust filter 19 is a low performance filter.

The pollen filter 20 is about the same size as the coarse dust filter 19, and is composed of a filter capable of capturing pollen. The pollen filter 20 is arranged so as to be superposed in the thickness direction of the coarse dust filter 19 and the housing 2.

In addition, the lower partition chamber 13 is provided with the partition member 21 which comprises a part of the lower fan casing 50, and the lower motor 22 is attached to this partition member 21. As shown in FIG. In addition, a fan 23 is attached to the rotating shaft 22a of the lower motor 22.

The fan 23 is a so-called sirocco fan. When the fan 23 is rotated, air is sucked from the front center side, and the air is discharged in the radial direction of the fan 23. Therefore, when the fan 23 is rotated, as shown by arrow D in FIG. 2, air outside the device is sucked from the lower intake port 9 and passes through the coarse dust filter 19 and the pollen filter 20, and the fan ( 23) flows in the radial direction. Further, the lower fan casing 50 is connected to the lower exhaust port 7 so that air flowing in the radial direction of the fan 23 is exhausted out of the device from the lower exhaust port 7 as indicated by arrow E in FIG.

As such, the lower end unit 26 includes the lower motor 22, the fan 23, the coarse dust filter 19, and the pollen filter 20 at the lower end of the housing 2.

3 is a block diagram showing the electrical configuration of the main part of the air cleaner 1. The air cleaner 1 is provided with a control unit 24 for controlling each part of the air cleaner 1. The control unit 24 includes a microcomputer, a ROM, a RAM, and the like. Moreover, the control part 24 is made to input the signal from the operation panel 5, the gas sensor 10, and the moving object detection sensor 11, The display form of the operation panel 5, an upper motor according to these signals. The drive of the 17 and the lower motor 22 is controlled.

Thus, when the operation panel 5 is operated by the user and the power of the air cleaner 1 is turned on, the gas sensor 10 and the moving object detection sensor 11 start detecting the pollutant in the air. . The operation operation based on the detection output of these sensors 10 and 11 will be described below.

Action 1

When the gas sensor 10 detects a gas component in the air, the upper motor 17 is driven to rotate the fan 18. Then, the air outside the device is sucked into the upper compartment 12 through the upper inlet 8. At this time, the air is purified through the fine dust filter 14 and the deodorizing filter 15. The purified air is then exhausted from the upper exhaust port 6.

Gases generated when smoking cigarettes and the fine dust accompanying them are easy to float in the upper space, and upwards where most of these gas components and accompanying dusts are present by detecting gas components by the gas sensor 10. The air in the space is sucked into the upper constituent unit 25 and purified to remove them efficiently. As the detection output of the gas sensor 10 increases (as the gas concentration increases), the control of the speed of the upper motor 17 becomes high, so that these can be removed more efficiently.

In addition, when the moving object detecting sensor 11 detects the movement of the human body, the lower motor 22 is driven to rotate the fan 23. Then, the air outside the device is sucked into the lower compartment 13 through the lower inlet 9. At this time, the air is purified through the coarse dust filter 19 and the pollen filter 20. The purified air is then exhausted from the lower exhaust port 7.

When a human moves, dust or pollen that has accumulated on the floor is blown off, so that the movement of the human body is detected by the moving object detecting sensor 11 so that the air in the lower space where most of the dust and pollen that has been blown is present in the lower component unit ( 26) It is possible to remove these dust and pollen efficiently by inhalation and purification. As the detection output of the moving object detection sensor 11 increases (moves become frequent), the control of the speed of the lower motor 22 becomes high, and these can be removed more effectively.

When both the gas sensor 10 and the moving object detecting sensor 11 detect the movement of the gas component and the human body, the speeds of the respective motors 17 and 22 are controlled by the respective sensors.

Action 2

In operation 1, the motor 17 of the upper component unit is selectively driven by the detection signal of the moving object sensor 11 by the detection signal of the gas sensor 10, respectively. However, in operation 2, the motor 17 of the upper configuration unit is driven more centrally than the motor 22 of the lower configuration unit by the detection signal of the gas sensor 10, and the detection signal of the moving object detection sensor 11 is used. The motor 22 of the lower component unit is driven more centrally than the motor 17 of the upper component unit.

Specifically, the operation shown in FIG. 4 is performed. That is, the detection level of the gas sensor 10 is set in four stages (the higher the value, the higher the gas concentration), and when the level is "0" (the air is not contaminated by the gas), the upper and lower motors 17 and 22 are used. ) Are all stopped, and when the level is "1", only the upper motor 17 is rotated at the lowest speed at the lowest speed. At the level "2", the upper motor 17 is rotated at a medium speed higher than the low speed. The lower motor 22 is rotated at low speed. Thereby, the air of the upper space in which the gas component and the micro dust accompanying it exist mostly is sucked in and purified by the upper structural unit 25, and it can remove them efficiently.

In addition, when the level is "3", it is regarded that contamination is spread throughout the room, and both the upper and lower motors 17 and 22 are rotated at medium speed, but the upper motor 17 is rotated at the highest speed and the lower motor 22 is rotated. ) May be rotated at medium speed.

Also, the detection level of the moving object detecting sensor 11 is also set in four stages (the larger the value, the more the movement of the moving object (human body) becomes), and the level is &quot; 0 &quot; The upper and lower motors 17 and 22 are stopped. When the level is &quot; 1 &quot;, only the lower motor 22 is rotated at the lowest speed and the lower motor 22 is rotated when the level is &quot; 2 &quot;. The upper motor 17 was rotated at the same time as the intermediate speed was rotated higher than the low speed. As a result, the air in the lower space in which most of the dust and pollen that has flown from the floor due to human movement is mainly taken in and purged by the lower constituent unit 26, so that they can be removed efficiently.

At the level "3", dust and the like are regarded as being blown up and spread throughout the room, and the upper and lower motors 17 and 22 are all rotated at medium speed. However, the lower motor 22 is rotated at the highest speed and the upper portion is rotated. The motor 17 may be rotated at an intermediate speed.

When both the gas sensor 10 and the moving object detection sensor 11 detect gas concentration and a moving object, operation | movement is performed based on the one where the detection level is larger. For example, when the detection level of the gas sensor 10 is "2" and the detection level of the moving object sensor 11 is "1", the upper motor 17 is rotated at an intermediate speed based on the gas sensor 10. The lower motor 22 is rotated at low speed.

When the detection level of the gas sensor 10 and the moving object sensor 11 is the same, the up-and-down motors 17 and 22 rotate by the same rotation speed. For example, when both detection levels are "2", both the up-and-down motors 17 and 22 rotate at medium speed.

In this way, by the operation 1 or the operation 2, efficient air purification suitable for the type of air pollution can be performed.

In addition, the upper constituent unit 25 and the lower constituent unit 26 are arranged in two upper and lower stages, and the inlet 8 for the upper constituent unit and the exhaust port 6 and the inlet 9 for the lower constituent unit and Since the exhaust ports 7 are respectively distributed up and down, more air can be sucked and purged from a wide range, and the purified air can be discharged to a wide range, thereby improving the capacity of the air cleaner. Although the capacity can be improved, the depth of the air purifier can be prevented from increasing so that the installation area can be kept small.

In addition, in the structure of the above embodiment, the fine dust filter 14 which is a high performance filter is used for the upper structure unit 25, and the coarse dust filter 19 which is a low performance filter relatively to the lower structure unit 26 is used. ) Can be used to purify the air efficiently. In other words, since small dust and the like float in the upper space and large dust and the like exist in the lower space, small dust and the like are reliably captured by the fine dust filter 14 of the upper constituent unit 25, Even the coarse dust filter 19 of the lower configuration unit 26 can be sufficiently captured. Therefore, the filter can be efficiently used. Moreover, compared with the case where the fine dust filter 14 is used for both the upper structure unit 25 and the lower structure unit 26, the fine dust filter 14 can be reduced and cost can be reduced.

The above description is for explaining the present invention and should not be interpreted as limiting the invention described in the claims or reducing the scope. In addition, each part structure of this invention is not limited to the said Example, A various deformation | transformation is possible within the technical scope as described in a claim.

For example, although the upper component unit 25 and the lower component unit 26 use different filters, respectively, one common filter can be used. In this case, what is necessary is just to provide the operation panel 5 provided in the center part of the housing 2 in the upper part or the side part of a housing.

In addition, although the exhaust ports 6 and 7 of the upper structural unit 25 and the lower structural unit 26 are distributed left and right, it is not necessary to specifically limit a place, if it is distributed up and down, for example, the upper structural unit ( The exhaust port of 25 may be provided on the upper surface of the housing 2, and the exhaust ports of the lower configuration unit 26 may be provided in two places on both the left and right sides of the housing 2. In addition, although the inlet ports 8 and 9 of the upper constituent unit 25 and the lower constituent unit 26 are also provided over approximately the entire front surface of the housing 2, the locations are particularly limited as long as they are dispersed up and down. There is no.

In addition, although the pyroelectric infrared sensor is used as the moving object detection sensor 11, the motion of a person may be detected by the Doppler effect of the ultrasonic wave reflected and returned to the moving person using an ultrasonic sensor.

According to the present invention, a component unit including a motor, a fan, and a filter is disposed in two stages up and down, and the intake and exhaust ports for the upper component unit and the inlet and exhaust ports for the lower component unit are distributed up and down, respectively. As a result, the air purifier can be prevented from increasing in depth even though it can suck and purify more air from a wide range and release the purified air to a wide range, thereby improving the air purifier's capacity. Can be kept small.

Furthermore, it has a gas sensor which detects the gas concentration in air, and a moving object sensor which detects the object moving inside, and controls the motor of the upper and lower component units separately according to the detection output of a gas sensor and a moving object sensor. It becomes possible to purify air efficiently.

For example, when the motor of the upper component unit is driven by the detection signal of the gas sensor and the motor of the lower component unit is driven by the detection signal of the moving object sensor, the air can be purified efficiently. That is, gas generated when smoking a cigarette and the fine dust accompanying it are easy to float in the upper space, and the upper space in which most of these gas components and accompanying dust exist by detecting gas components by a gas sensor. Can be removed efficiently by inhaling and purifying the air into the upper component unit. In addition, when the human moves, dust or pollen that has accumulated on the floor is blown off, so that the movement of the human body is detected by the moving object sensor, so that air in the lower space in which most of the blown dust or pollen exists is sucked into the lower component unit. By purification, these dusts and pollen can be removed efficiently.

Further, the motor of the upper component unit is driven (e.g., driven at a high speed) more intensively than the motor of the lower component unit by the detection signal of the gas sensor, and the motor of the lower component unit is driven upward by the detection signal of the moving object sensor. Even if driven more intensively than the motor of the constituent unit (for example, driven at a higher speed), as in the case described above, most of the gas generated when smoking a cigarette floating in the upper space or the like is attached to the fine dust and the lower space. The dust and pollen that has flown from the floating floor can be efficiently removed by the upper and lower components.

Furthermore, if the detection output level by the gas sensor and the detection output level by the moving object sensor are compared, and the motors of the upper and lower constituent units are controlled based on the larger detection output level, it is suitable for the type of air pollution. Air purification can be performed efficiently.
