Description

  The present invention relates to a dust removal system that removes dust in indoor air.

  In recent years, the number of patients with pollen allergy and house dust allergy has increased, which has become a major social problem. Especially in recent years, since the airtightness of houses has increased dramatically, it is obliged to ventilate for 24 hours by the Building Standards Law. However, it is difficult to remove pollen and house dust with a size of several microns or more, and floor cleaning is difficult. The current situation is that it is frequently required. Under such circumstances, household dust removal devices are effective in purifying indoor air, so demand is rapidly increasing. Currently, the penetration rate exceeds 35% and will continue to spread further in the future. I can expect.

  Conventional home air purifiers have a suction port on the front or side of the main body, suck in room air in the vicinity of the suction port, provide a blower outlet at a position that hits the upper side of the main body, and follow the upward blowing louver A form in which the wind is blown only in the direction is typical. In such a conventional method, the room air can be circulated in the space and the room air sucked from the suction port can be efficiently purified, but there is a problem that only the room air can be purified. In the first place, pollen and house dust with a size of several microns or more do not float in the air for a long time even if they soar, and most of them are sedimented by gravity and deposited on the floor. For this reason, since the domestic air cleaner can only circulate room air, there has been a problem that it is difficult to remove pollen and house dust accumulated on the floor surface.

On the other hand, there is a dust collector and a dust collection system that employ an air cleaning method that can effectively and quickly clean air stains generated in a room (see, for example, Patent Document 1). This is a system that sucks indoor air into the main body and blows it out, a dust collecting means that collects dust contained in the room air upstream of the air blowing means, and an air inlet that sucks indoor air into the main body And by installing a plurality of dust collectors provided with outlets for blowing out the intake air, a circulating flow flows along the floor and ceiling surfaces, so that dust can be collected effectively. It is.
Also provided is a first intake means that can be opened and closed provided on the side of the main body, a second intake means that can be opened and closed provided at the lower part of the main body, and a control means for opening and closing the first intake means and the second intake means. There is an air cleaner (see, for example, Patent Document 2). By providing the air intake means as described above, pollen and house dust that have been swollen by human action can be removed.
Furthermore, there exists an air cleaner provided with the air path which blows the air before discharging | emitting from an exhaust port toward the floor which is an installation surface of a dust removal apparatus (for example, refer patent document 3). This can blow up the pollen and house dust that accumulates on the floor surface and soar into the air.

JP 2003-79540 A (Page 6, FIG. 5) JP 2008-212463 A (8th and 9th pages, FIG. 1) JP 2006-136804 A (4th, 5th page, FIG. 2)

However, the dust collector and the dust collection system according to Patent Document 1 are designed to allow a circulating flow to flow along the floor surface and the ceiling surface, and the amount of air circulation can be increased. When the flow of air is unidirectional, there is a problem that it is not possible to create an air flow state that soars dust on the floor surface with high efficiency.
Moreover, in this dust collector, the main body is restrained in the direction of the floor surface and the ceiling surface and is fixed by a fixture. For this reason, the effect in a specific area can be obtained, but when operating in a different area, the fixture must be removed and installed again, and the height of the body is up to the ceiling surface For this reason, there is a problem that workability is very poor including the work of attaching to the ceiling surface.

Moreover, although the air cleaner which concerns on patent document 2 can remove the pollen and house dust which soared by operation | movement of a person, it cannot actively raise the pollen and house dust which accumulated on the floor surface. Therefore, there is a problem that pollen and house dust existing in the room cannot be efficiently removed.
In addition, pollen and house dust generated at a relatively long distance from the suction port fall again to the floor due to gravity settling before reaching the suction port, so it can be collected at the suction port with high efficiency. May be limited to pollen and house dust deposited on the floor near the inlet.

Furthermore, the air cleaner according to Patent Document 3 can blow up the air to pollen and house dust that accumulates on the floor surface, and the wind blown to the floor is the front direction of the main body, There is a problem that the pollen and house dust that have risen are pushed out toward the front of the main body. In this case, in order to form the air path to the suction port, it is necessary for the blown air to form an ascending air current. However, Patent Document 3 does not have such description.
In addition, even if the blown wind collides with a wall or the like existing in front and rises, if it is relatively far away from the suction port, it will fall to the floor again due to gravity settling before reaching the suction port. Therefore, there is also a problem that it cannot be collected at the suction port with high efficiency.
Furthermore, regardless of the presence of a person, the pollen and house dust on the floor surface may rise, so there is a risk that the pollen and house dust will rise in the indoor space where the person exists.

  The present invention has been made in order to solve the above-described problems. Soot pollen and house dust deposited on the floor are raised in the air, and soared pollen and house dust are increased. The purpose is to clean and remove indoor air efficiently.

A dust removal system according to the present invention includes a plurality of dust removal devices for removing dust in room air, and each of the dust removal devices includes a suction port through which the room air is sucked into the main body, and the suction port. and air cleaning means for dust is removed and clean air from the indoor air sucked from the air outlet in which the clean air is blown out of the body, to communicate the suction port and the air outlet, the air and air passage cleaning means is arranged, suck the indoor air into the main unit from the suction port, send the clean air through the air passage to said outlet, and then blowing the clean air from the outlet comprising a blowing means, the at least single one of the plurality of dust removing device is provided with position detecting means for detecting the position of the other of the dust removing device, said dust removal of the counterpart by the position detecting means The position of the apparatus is confirmed, and the clean air blown out through the air outlet collides with the clean air blown out through the air outlet by the counterpart dust removing device, and the plurality of dust removals At least one of the apparatuses includes a main body rotating means for rotating at least a part of the main body or the entire main body around a predetermined axis, and the main body rotating means includes at least a part of the main body or the entire main body. By rotating, the position detection means switches the detection direction for detecting the position of the other dust removing device .

According to the present invention, a plurality of dust removing devices can detect each other's position and collide each blowing air, so that dust such as pollen or house dust on the floor can be raised, By soaring, it can be sucked into the suction port of each device by riding in the suction air, and dust in the indoor air can be removed with high efficiency, and the frequency of human cleaning with a vacuum cleaner etc. is reduced, saving time and labor Dramatically reduced.
Moreover, each dust removal apparatus should just be installed in the same space, does not need to fix a place with a fixture etc., and is very excellent in workability | operativity at the time of installation.

The heat source part is not particularly limited, and for example, a heater using a nichrome wire or a PTC ceramic heater is used. Or when it is set as the structure provided with the refrigerating cycle system in the main body 102, it is good also as what uses the heat | fever generate | occur | produced by this. Moreover, said blower outlet 104 has the shape which assembled the board in parallel, and is provided with the louver (not shown) which can switch the direction of the clean air which blows off up and down and right and left. The position detection sensor 105 is an infrared sensor of a type that receives infrared rays radiated from an object and generates a thermoelectromotive force according to the amount of energy, but detects the absolute amount (temperature) of the energy. It may be configured by a pyroelectric infrared sensor or a thermopile sensor that can perform the above, or an ultrasonic sensor that measures a distance, an infrared laser, a geomagnetic sensor, a radio wave sensor, or the like. And said infrared radiation | emission part 106 should just emit infrared rays, such as LED or a discharge lamp.
The "air purifying means" described in the claims of the present invention is an air purifying filter or an air purifying filter 601 described later, "blower means" is a blower, "position detecting means" is a position detection sensor 105, or described later. The position detection sensor 205, the position detection sensor 505, the position detection / human body detection sensor 109 or the position detection / human body detection sensor 209, and the “heating means” correspond to a heat source unit.

In the present embodiment, an air cleaning filter is used as a device for cleaning indoor air, but the present invention is not limited to this. For example, an electric dust collector, an air cleaning filter, and an electric dust collecting device are used. A combination of devices may also be used.
Further, as shown in FIG. 1, the suction port 103 is installed on the upper surface of the main body 102 and sucks room air from above, but is not limited thereto, and the front surface of the main body 102 is not limited thereto. Or it is good also as a structure which is installed in a side surface and inhales indoor air from the front direction or a horizontal direction, respectively. Or it is good also as a structure installed in any one or all surfaces among the upper surface of the main body 102, a front surface, or a side surface.

  The second dust removing device 201 has the same configuration as the first dust removing device 101, and includes a main body 202, a suction port 203, a cleaning filter (not shown), and a heat source (not shown). 2), an air outlet 204, a blower (not shown), a position detection sensor 205, an infrared radiation unit 206, a distance measuring means 207, and a main body rotating means (not shown). These operations and functions are the same as those provided in the first dust removing device 101.

(Dust removal operation of the dust removal device)
Next, the dust removing operation of the dust removing device will be described with reference to FIG.
First, when a blower installed in the main body 102 in the first dust removing device 101 is driven, a suction air 111 that is a flow of room air is generated in the vicinity of the suction port 103, and the suction air 103 passes through the main body 102. The suction wind 111 is sucked in. The indoor air sucked into the main body 102 as the suction air 111 is cleaned by the air purification filter to remove dust such as pollen and house dust, and becomes purified air. The clean air purified by the normal air filter is warmed by the heat source unit, and blown out as a blown air 112 from the blower outlet 104 toward the floor surface obliquely below.

  Also in the second dust removing device 201, the suction air 211 is sucked into the main body 202 from the suction port 203 and the clean air is blown out from the air outlet 204 by the same operation as the first dust removing device 101. It is blown out toward the floor surface diagonally below.

(Dust removal system updraft generation operation)
Next, in the dust removal system constituted by the first dust removal device 101 and the second dust removal device 201, the operation of raising dust such as pollen and house dust present on the floor surface will be mainly described.

  The first dust removing device 101 detects the infrared rays emitted from the infrared radiation unit 206 provided in the second dust removing device 201 by the position detection sensor 105 provided in the first dust removing device 101, thereby removing the second dust. Check the position of the device 201. At this time, the first dust removing device 101 can be easily operated by rotating the main body 102 by the main body rotating means included in the first dust removing device 101, thereby widening the viewing angle detected by the position detection sensor 105. The position can be confirmed. Here, the first dust removing device 101 arbitrarily changes the direction of the blown air 112 blown out from the air outlet 104 by controlling the main body rotating means or the louver provided in the air outlet 104. In this case, the blowing air 112 is blown out from the outlet 104 in the direction of the second dust removing device 201 whose position has been confirmed.

  Similarly, the second dust removing device 201 detects the infrared rays emitted from the infrared radiation unit 106 provided in the first dust removing device 101 by the position detection sensor 205 provided in the second dust removing device 201, thereby The position of the dust removing device 101 is confirmed. At this time, the first dust removing apparatus 201 can be easily installed in the first dust removing apparatus 101 by rotating the main body 202 by the main body rotating means included in the first dust removing apparatus 201 and widening the viewing angle detected by the position detection sensor 205. The position can be confirmed. Here, the second dust removing device 201 arbitrarily changes the direction of the blown air 212 blown out from the air outlet 204 by controlling the main body rotating means or the louver provided in the air outlet 204. In this case, the blown air 212 is blown out from the blower outlet 204 toward the second dust removing device 201 whose position has been confirmed.

  The position detection sensor 105 provided in the first dust removal device 101 and the position detection sensor 205 provided in the second dust removal device 201 operate in conjunction with each other by confirming the positions as described above. The blown air 112 and the blown air 212 are blown toward the dust removing device, and the blown air 112 and the blown air 212 are caused to collide with each other. The blown air 112 and the blown air 212 that have collided generate an updraft. The rising airflow causes floor surface dust 301 such as pollen or house dust present on the floor surface to rise upward and become floating dust 302. This floating dust 302 is further lifted upwards to become rising dust 303 and rides on the suction air 111 on the first dust removing device 101 side or the suction air 211 on the second dust removing device 201 side, It is transported in the direction of the first dust removing device 101 or the second dust removing device 201 and is sucked into the suction port 103 or the suction port 203. Moreover, since the blowing air 112 in the 1st dust removal apparatus 101 and the blowing air 212 in the 2nd dust removal apparatus 201 are each warmed by the heat source part with which each is provided, since warmed air tends to rise, it is larger. Generate updraft. In addition, the warming blowing air 112 and the blowing air 212 should just be temperature higher than room temperature.

As described above, the first dust removing device 101 and the second dust removing device 201 detect the positions of each other and collide with the blowing air, so that dust such as pollen or house dust on the floor is raised. Further, when the dust soars, it is sucked into the suction port provided in each dust removing device on the suction wind, and the dust in the room air can be removed with high efficiency.
In addition, the highly efficient dust removal operation as described above reduces the frequency of human cleaning with a vacuum cleaner or the like, and dramatically reduces time and labor.
The first dust removing device 101 and the second dust removing device 201 are each provided with a louver at each outlet, and further provided with a main body rotating means, and the blowing direction of the blowing air 112 and the blowing air 212 is changed. Since it can be freely changed, it is possible to cause the blowing air 112 and the blowing air 212 to collide with each other with high accuracy, and it is possible to eliminate the need to consider the installation position and orientation of the main body 102 and the main body 202. .
Moreover, since the 1st dust removal apparatus 101 and the 2nd dust removal apparatus 201 are each provided with a heat-source part and can blow out the warm blowing air 112 and the blowing air 212, they generate a bigger upward airflow. Since dust such as pollen and house dust can be lifted up efficiently, dust removal can be realized more efficiently.
Furthermore, the first dust removing device 101 and the second dust removing device 201 only have to be installed in the same space, and it is not necessary to fix the place with a fixture or the like, so that the workability at the time of installation is improved. Very good.

In the present embodiment, the first dust removing device 101 and the second dust removing device 201 are each provided with a position detection sensor. However, the present invention is not limited to this, and at least one of the positions is located. A configuration including a detection sensor may be employed. At this time, the main body rotation driving means may be provided only in the dust removing device provided with the position detection sensor. However, in order to collide the blown wind efficiently, a configuration in which position detection sensors are provided with each other is preferable.
In the present embodiment, the first dust removing device 101 and the second dust removing device 201 are each provided with a louver. However, the present invention is not limited to this, and one of them is provided with a louver. It is good. The same applies to the heat source unit.
In the present embodiment, the main body rotating means is configured to rotationally drive the main body 102 about a predetermined axis of the main body 102. However, the present invention is not limited to this, and at least the position detection sensor 105 is provided. A part of the main body 102 or a part of the main body 102 provided with at least the air outlet 104 may be rotationally driven.
Further, in the present embodiment, the first dust removing device 101 (or the second dust removing device 201) is positioned by rotating the main body 102 (or the main body 202) by the main body rotating means provided in itself. Although the configuration is such that the viewing angle detected by the detection sensor 105 (or position detection sensor 205) is widened, the present invention is not limited to this, and is connected to the position detection sensor 105 (or position detection sensor 205). The detection angle of the position detection sensor 105 (or the position detection sensor 205) may be switched by the rotation driving unit having the above rotation axis so that the viewing angle to be detected is widened.

FIG. 2 is a diagram illustrating an updraft surface of room air in the dust removal system according to Embodiment 1 of the present invention.
As shown in FIG. 2, the distance measuring means 107 provided in the first dust removing apparatus 101 and the distance measuring means 207 provided in the second dust removing apparatus 201 are respectively connected to the counterpart dust removing apparatus. And measure the distance. At this time, the first dust removing device 101 (or the second dust removing device 201) makes the shortest distance between the dust removing devices based on the distance information measured by the distance measuring unit 107 (or the distance measuring unit 207). The inter-device coupling line 401, the intermediate point 402 of the inter-device coupling line 401, and the intermediate plane 403 that intersects the intermediate point 402 and is perpendicular to the inter-device coupling line 401 are obtained. Then, the first dust removing device 101 and the second dust removing device 201 perform control so that the rising air flow generated by causing the blown air to collide with each other rises so as to include the intermediate plane 403.

  With the above-described operation, the first dust removing device 101 and the second dust removing device 201 can generate a wide range of updrafts by the respective blowing winds, and can increase the soaring of dust such as pollen or house dust. Can be realized efficiently.

  In the present embodiment, the dust removing system is configured by two dust removing devices, ie, the first dust removing device 101 and the second dust removing device 201. However, the present invention is not limited to this. Alternatively, it may be configured by three or more dust removing devices and operated in conjunction with each other.

Embodiment 2. FIG.
(Overall configuration of dust removal system)
FIG. 3 is a diagram showing the configuration of the dust removal system and the indoor air circulation operation according to Embodiment 2 of the present invention. The following description will focus on differences from the configuration and operation of the dust removal system according to Embodiment 1 described above.
As shown in FIG. 3, in the present embodiment, a second dust removing device 501 is installed instead of the second dust removing device 201 in the first embodiment. The second dust removing device 501 includes a cylindrical main body 502, a suction port 503 that is installed on the upper surface of the main body 502 and sucks room air into the main body 502 as a suction air 511, and pollen contained in the sucked room air. Or an air purifying filter (not shown) installed in the main body 502 for removing and cleaning dust such as house dust, a heat source part (not shown) for warming clean air cleaned by the air purifying filter, A blower outlet 504 for blowing clean air warmed by the heat source unit, a blower (not shown) for circulating indoor air sucked from the suction inlet 503 to the air passage in the main body 502, and the first dust removing device 101 A position detection sensor 505 that is a non-contact type infrared sensor for detecting the position of the infrared ray, an infrared radiation unit 506 that emits infrared rays to the outside, and a first dust removing device Distance measuring means 507 measures the distance between 101 and comprises a body rotating means for rotating the body 502 about a predetermined axis of the body 502 (not shown).

  The air outlet 504 is arranged over the entire circumference of the cylindrical main body 502, and blows out the air blow 512 around the entire circumference and toward the floor surface obliquely below. Moreover, this blower outlet 504 has the shape which assembled the board in parallel, and is provided with the louver (not shown) which can switch the direction of the clean air which blows off up and down and right and left.

(Effect of Embodiment 2)
As in the above configuration, the air outlet 504 in the second dust removing device 501 blows the blown air 512 around the entire circumference and toward the floor surface obliquely below. Dust such as pollen or house dust present on the surrounding floor can be raised. At this time, when the second dust removing device 501 is installed in the vicinity of the indoor wall, the blown air 512 blown out from the blowout surface of the blowout port 504 facing the wall side is The dust that has collided with the wall to become an updraft and soared by the updraft, rides on the suction air 111 in the first dust removal device 101 or the suction air 511 in the second dust removal device 501, respectively. Since it is sucked into the apparatus, highly efficient dust removal can be realized.
Furthermore, by attaching the louver provided in the air outlet 504 upward, it is possible to remove dust adhering to the curtain, furniture, television, AV equipment, or the like.

In the present embodiment, the main body 502 is configured to be cylindrical, but is not limited thereto, and may have other shapes.
Further, as shown in the first embodiment, the position detection sensor 505 is connected to the position detection sensor 505 instead of the main body rotation means in order to widen the angle of view to be detected, and is driven to rotate with one or more rotation axes. By changing the detection direction of the position detection sensor 505 by means, the viewing angle to be detected may be widened. In this case, the main body rotation means may not be provided.
Furthermore, although the dust removal system in this Embodiment is comprised by the 2nd dust removal apparatus 501 provided with the 1st dust removal apparatus 101 and the cylindrical main body 502, it is not restricted to this. Any of the dust removing devices may be configured by a dust removing device having a cylindrical main body similar to the second dust removing device 501.

Embodiment 3 FIG.
(Overall configuration of dust removal system)
FIG. 4 is a diagram showing the configuration of the dust removal system and the indoor air circulation operation according to Embodiment 3 of the present invention. The following description will focus on differences from the configuration and operation of the dust removal system according to Embodiment 1 described above.
As shown in FIG. 4, a liquid particle generation unit 108 is provided on the upper surface of the main body 102 in the first dust removing device 101.

(Dust removal operation of the dust removal device)
As in the first dust removing device 101 in the first embodiment, when the blower installed in the main body 102 is driven, a suction air 111 that is a flow of room air is generated in the vicinity of the suction port 103, Suction air 111 is sucked into the main body 102 from the mouth 103. At this time, the liquid particle generating unit 108 releases liquid particles 121 such as water, and the rising dust 303 such as pollen or house dust floating above the liquid particle generating unit 108 is adsorbed by the liquid particles 121, and the dust adsorption Particles 304 are formed. Since the dust adsorbing particles 304 increase in weight, they drop in weight and are sucked into the suction port 103 by riding on the suction air 111, and dust is removed inside the main body 102.

(Effect of Embodiment 3)
As described in the first embodiment, as described in the first embodiment, dust such as pollen or house dust is soared by the updraft generated by the first dust removing device 101 and the second dust removing device 201. In addition to removing the dust by putting the dust on the suction air 111 and the suction air 211 and removing the dust in the main body, it is adsorbed to the liquid particles and dropped by gravity. Furthermore, the dust removal capability can be improved.

Although the liquid particles generated by the liquid particle generator 108 in the present embodiment have been described as being water or the like, the present invention is not limited to this, and other liquids may be used.
Further, as shown in FIG. 4, the liquid particle generating unit 108 is configured to be installed only in the first dust removing device 101. However, the configuration is not limited to this, and the second dust removing device 201 side is not limited thereto. Or it is good also as a structure installed in both the 1st dust removal apparatus 101 and the 2nd dust removal apparatus 201. At this time, when the liquid particle generating unit is installed in both the first dust removing device 101 and the second dust removing device 201, the dust removing ability can be further improved.
Further, as shown in FIG. 5, it goes without saying that a second dust removing device 501 including a cylindrical main body 502 may be installed instead of the second dust removing device 201 in FIG. 4. Also in this case, as shown in FIG. 5, the liquid particle generation unit 108 is configured to be installed only in the first dust removing device 101, but is not limited to this, and the second particle generator 108 is not limited thereto. It is good also as a structure installed in the dust removal apparatus 501 side or in both the 1st dust removal apparatus 101 and the 2nd dust removal apparatus 501.

Embodiment 4 FIG.
(Overall configuration of dust removal system)
FIG. 6 is a diagram showing the configuration of the dust removal system and the indoor air circulation operation according to Embodiment 4 of the present invention. The following description will focus on differences from the configuration and operation of the dust removal system according to Embodiment 1 described above.
As shown in FIG. 6, in the present embodiment, the main body 102 of the first dust removing device 101 is the second dust that is the counterpart in place of the position detection sensor 105 in the first embodiment. In addition to a position detection function for confirming the position of the removal device 201, a position detection and human body detection sensor 109 is also provided which has a human body detection function for detecting the presence or absence of a nearby person. Similarly, in the second dust removing device 201, the main body 202 has a position detection function for confirming the position of the first dust removing device 101 which is the counterpart in place of the position detection sensor 205 in the first embodiment. In addition, a position detection / human body detection sensor 209 having a human body detection function for detecting the presence or absence of a nearby person is provided.
The “human body detection means” described in the claims of the present invention corresponds to the position detection / human body detection sensor 109 or the position detection / human body detection sensor 209.

(Configuration of air purification filter and air path switching device)
7 and 8 are diagrams showing configurations of an air purification filter and an air path switching device provided in the dust removing device according to Embodiment 4 of the present invention.
The main body 102 in the first dust removing device 101 and the main body 202 in the second dust removing device 201 are each provided with an air purifying filter 601 as shown in FIGS. This air purifying filter 601 includes a low-pressure loss filter 602 in which the pressure loss of circulating air is small and a high-pressure loss filter 603 in which the pressure loss of circulating air is large. An air path switching device 604 is provided in the air path upstream of the air cleaning filter 601. As shown in FIG. 7, the air path switching device 604 switches the air path so as to circulate air as the low pressure loss filter circulating air 612 that flows only to the low pressure loss filter 602, or is shown in FIG. As described above, the air path is switched so that air is circulated as the high-pressure loss filter circulation air 613 that circulates only through the high-pressure loss filter 603.
