Abstract

A dust collector is provided with fan devices (7) arranged in a room and generating a dust collecting airflow (12) in the entire room by changing the direction and volume of the airflow in a manner associated with each other, and the dust collector is also provided with a dust collecting section (8) provided near a floor surface (5a) in the room and collecting dust moving with the dust collecting airflow (12). The dust collecting airflow (12) is generated as a swirl flow having a rotation axis substantially perpendicular to the floor surface (5a). This causes that force with which the dust tries to move with the dust collecting airflow (12) and force with which the dust tries to move downward by gravity do not cancel each other and, as a result, the dust can more easily move with the airflow, enabling easier collection of the dust.

Description

Dust collector

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a dust collection apparatus that generates an air flow in a room and collects dust into a dust collection unit.

Heretofore, as a dust collecting apparatus of this type, for example, a dust collecting unit having a blower and having an exhaust port directed upward is disposed at a corner of the room, and a dust collecting airflow circulating in the room by exhaust air from the exhaust port is used. There is an example which collects dust in a dust collection part by making it generate (for example, refer to patent documents 1).

FIG. 4 is a side view of the dust collecting apparatus in a state where the conventional dust collecting apparatus described in Patent Document 1 is installed in a room and a side view of the indoor space thereof. In this indoor space, the floor surface 5a is disposed on the lower side and the ceiling surface 5b is disposed on the upper side.

In FIG. 4, the dust collection unit 1 has a blower 2, and an intake port 3 is provided on the front surface. An exhaust port 4 is provided at the upper side. The dust collection unit 1 is placed at a corner of the room, and the air exhausted from the exhaust port 4 rises from the floor surface 5a to the ceiling surface 5b to generate a dust collection air flow 5 circulating in the room. The dust collection air flow 5 flows upward along the wall surface 5c and then flows along the ceiling surface 5b. Furthermore, it flows along the wall surface 5 c opposite to the dust collection unit 1, and then flows along the floor surface 5 a and is sucked into the air inlet 3. Dust is collected to the dust collection unit 1 by the dust collection air flow 5.

In addition, there is an example in which a plurality of dust collecting units having a blower and a plurality of switchable air inlets and air outlets are disposed in the room and synchronized operation is performed to enhance the dust collection performance (for example, Patent Document 2) reference).

FIG. 5 is a side view of the dust collecting apparatus 1 in a state where the conventional dust collecting apparatus 1 described in Patent Document 2 is installed in a room and the indoor space thereof as viewed from the side. In this indoor space, the floor surface 5a is disposed on the lower side and the ceiling surface 5b is disposed on the upper side.

In FIG. 5, the dust collection unit 1 has a blower 2. In addition, the dust collection portion 1 has a height from the floor surface 5a to the ceiling surface 5b, and the intake port 3 (3a, 3b) and the exhaust port 4 (4a) are provided at both the floor surface 5a and the ceiling surface 5b. , 4b). When intake is performed from the intake port 3a near the ceiling surface 5b, exhaust is performed from the exhaust port 4b near the floor surface 5a. Conversely, when intake is performed from the intake port 3b near the floor surface 5a, exhaust is performed from the exhaust port 4a near the ceiling surface 5b. In addition, a plurality of dust collection units 1 (two in FIG. 5 are illustrated) are disposed in the room. Exhaust air is exhausted from the exhaust port 4b near the floor surface 5a of a certain dust collection unit 1 and intake is performed from the air intake port 3b near the floor surface 5a of the other dust collection unit 1 Occurs. Also, by switching the air inlet 3 (3a, 3b) and the air outlet 4 (4a, 4b) in reverse, the dust collection air flow 5 also reaches the shadow of furniture etc. which the dust collection air flow 5 did not reach in the first operation. And can collect more dust.

However, in the above-described conventional configuration, the dust collection air flow is a swirling flow having a rotation axis in a substantially horizontal direction on the floor surface 5a in the room, and depending on the position in the room, for example, near the wall surface 5c shown in FIGS. There will be a flow towards you. Where the air flow is directed upward, there is a problem that the force of the dust moving downward by gravity and the force of the dust moving on the swirling flow cancel each other and the dust becomes difficult to move.

In addition, although a central air flow is generated toward the center of the swirling flow along with the swirling flow, this air flow also flows upward depending on the position in the room. Therefore, with regard to the central air flow as well, there is a problem that the force of the dust moving downward due to gravity and the force of the dust moving on the central air flow cancel each other and the dust becomes difficult to move.
Tokuhei 6-24641 JP 2003-79540 A

The present invention solves the above-mentioned conventional problems, and by efficiently setting the dust collection air flow in the entire room as an air flow suitable for collecting dust without using the air flow that cancels the gravity of the dust. Abstract: Provided is a dust collecting apparatus capable of collecting dust.

That is, the dust collecting apparatus according to the present invention is disposed in one room in a room, or in a plurality in cooperation with each other in a room to change the wind direction and the air volume to generate dust collecting air flow in the entire room. And a dust collection unit for collecting dust moving on the dust collection air flow.

With such a configuration, the dust collection air flow is a swirling flow having a rotation axis substantially perpendicular to the floor surface in the entire room. By making the dust collection air flow into such a swirling flow, the air flow flows horizontally in any space in the room. As a result, since the air flow in the vertical direction is eliminated, the force of the dust moving downward by gravity and the force of moving on the swirling flow can not be offset each other. Also, since the central air flow toward the center of the swirling flow generated along with the swirling flow is also a horizontal flow, the force of the dust moving downward by gravity and the force of moving on the central air flow are canceled I will not go away. Therefore, the dust can move more easily without staying in a predetermined area of any space in the room.

That is, the dust collection device of the present invention generates a swirling flow having a rotation axis substantially perpendicular to the floor surface in the entire room. This makes it easier for the dust to move on the air flow because the gravity applied to the dust and the force to move on the air flow do not cancel each other, and a dust collection device that collects dust more efficiently can be realized. .

Hereinafter, an embodiment of the present invention will be described using the drawings. In the following drawings, the same components are denoted by the same reference numerals, and the description may be omitted. The present invention is not limited by the present embodiment.

Embodiment 1
FIG. 1 is a perspective view of a room provided with a dust collecting apparatus according to a first embodiment of the present invention.

In FIG. 1, a plurality of air blowers 7 (7a, 7b) are provided indoors, and a dust collection unit 8 is provided near the floor surface 5a. Further, an air intake device 9 integrally formed with the air blower 7 is provided in the room, and air is blown to the room. In addition, an exhaust device 10 integrally formed with the dust collection unit 8 is provided indoors, and an air conditioner 11 a as an air conditioner 11 is provided near the ceiling. Here, the blower 7a and the intake device 9 are connected and integrated on the back side of the wall surface 5c by a blower pipe (not shown) or an intake pipe (not shown). Further, the dust collection unit 8 and the exhaust device 10 are disposed and integrated in the same housing (not shown).

The blower 7a, the intake device 9 and the air conditioner 11a provided near the ceiling are configured to perform ventilation so as to generate a swirling flow having a rotation axis substantially perpendicular to the floor surface 5a. Therefore, the blower 7 b in the vicinity of the floor surface 5 a is configured to blow air toward the dust collection unit 8. With these configurations, the swirling flow has a rotation axis substantially perpendicular to the floor surface 5a. That is, as shown in FIG. 1, a part of the blower 7 b operates to generate a swirling flow, and the rest operates to blow air toward the dust collection unit 8.

By the way, on the floor surface 5a, a part of the air flow is operated to generate a swirling flow by the air flow toward the dust collection part 8 by the three air blowers 7b placed at the corners of the room. The remaining air flow is configured to form a dust collection air flow 12 which is a swirling flow such that the rotation shaft is positioned near the dust collection unit 8.

In the room, a dust sensor 13 is provided which irradiates laser light (not shown) and detects the presence or absence of dust with scattered light of the laser light from dust.

The operation and action of the dust collecting apparatus configured as described above will be described below.

First, when the dust collector is activated, the dust sensor 13 checks the presence or absence of dust in the room. When dust is detected, the blowers 7 (7a, 7b), the intake device 9, the exhauster 10, and the air conditioner 11 are operated to generate the dust collection air flow 12.

The blower 7 (7a, 7b), the intake device 9, the exhaust device 10, and the air conditioner 11 adjust the air volume and the wind direction so that the air flow generated by each other does not cancel each other, and generate the collected air flow 12 serving as a swirling flow. ing. Dust in the room is conveyed by the dust collection air flow 12 and collected to the dust collection unit 8.

The dust collection air stream 12 starts from the suction device 9 and flows to the exhaust system 10 so as to swirl the entire room. Since the dust collection air flow 12 flows in the entire room, dust in the entire room can be collected.

Further, the dust collection air flow 12 is a swirling flow having a rotation axis substantially perpendicular to the floor surface 5a. Therefore, the force received by the dust from the swirling air flow is only the force in the horizontal direction and the force in the downward direction, and does not cancel the gravity acting in the downward direction, so that the dust can be collected more efficiently.

Further, since the air flow drawn toward the center direction of the swirling flow generated in the vicinity of the floor surface 5a along with the swirling flow also becomes a flow in the horizontal direction, the force received from the attracted airflow also cancels the gravity acting in the downward direction. Dust can be efficiently collected to the center of the swirling flow.

After the operation for a predetermined time, the dust sensor 13 checks again for the presence or absence of dust, and if there is no dust, the dust collection device is stopped.

In the present embodiment, the dust collection apparatus is configured to form only the dust collection air flow 12 of a certain pattern. However, the air flow rate and the air flow direction of the air blower 7, the air suction device 9, the exhaust air device 10, and the air conditioner 11 may be adjusted and switched to different dust collection air streams 12 to improve dust collection efficiency.

In the first embodiment, the air flow from the air blower 7a, the air suction device 9 and the air conditioner 11a is used to generate a swirling flow having a substantially vertical rotation axis with respect to the floor surface 5a. . However, the dust collection device of the present invention is not limited to the above configuration, and the same effect can be obtained even if the air blower 11a is replaced with the air conditioner 11a.

A series of operations of air blower 7, intake device 9, exhaust device 10, air conditioner 11, dust sensor 13 and adjustment of air volume and air direction in the first embodiment are electrically controlled by control means not shown. Are configured.

That is, the dust collecting apparatus according to the present invention is disposed in one room in a room, or in a plurality in cooperation with each other in a room to change the wind direction and the air volume to generate dust collecting air flow in the entire room. And a dust collection unit that collects dust moving on the dust collection air flow.

With such a configuration, dust can be more easily transferred by moving in an air stream, and dust can be collected more efficiently.

Further, the dust collection air flow is a swirling flow having a rotation axis substantially perpendicular to the floor surface, and the blower is one of the blowers such that the rotation axis of the swirling flow on the floor is positioned at the dust collection portion. The unit operates to generate a swirling flow, and the rest is configured to blow air toward the dust collection unit.

With such a configuration, the force of the dust moving up in the dust collecting air flow and the force of moving down by gravity do not cancel each other, and the dust does not become difficult to move. Can be moved more easily on the air stream, and dust can be collected more efficiently.

Further, the rotational shaft of the swirling flow is formed at a position close to the dust collection portion, and the dust can be efficiently moved to the dust collecting portion and collected on the swirling flow. Furthermore, dust can be more efficiently collected to the dust collection portion also by the suction air flow drawn toward the center of the swirling flow generated near the floor surface along with the swirling flow.

Here, the blower 7a and the intake device 9 are connected and integrated on the back side of the wall surface 5c by a blower pipe (not shown) or an intake pipe (not shown). Further, the dust collection unit 8 and the exhaust device 10 are disposed and integrated in the same housing (not shown).

The blower 7a, the intake device 9 and the exhaust device 10 adjust the air flow and the air flow so that the air flow generated by each other does not cancel each other, and generate the swirling flow having a rotation axis substantially perpendicular to the floor surface 5a. Is configured to

Further, in FIG. 2 apart from the dust collection unit 8, for example, the blower 7c at the central portion of the room has a blowing area larger than that of the other blowers 7a. Therefore, the air volume is the same as that of the other air blowers 7a, and air can be blown at a slow air velocity.

According to the above-described configuration, the amount and direction of air flow are adjusted so that the air currents generated from one another do not cancel each other, and the dust collection air flow 12 serving as a swirling flow having a rotation axis substantially perpendicular to the floor surface 5a is generated.

First, when the dust collecting apparatus is activated, the air suction device 9, the air blowing device 7a, the air blowing device 7c, and the exhaust device 10 blow air to generate the dust collection air flow 12.

The air volume of the air blower 7c separated from the dust collection unit 8 is the same as that of the other air blowers 7a, and the air flow is slow at a slow wind speed, so that the balance of the swirling flow is broken. The rotational shaft of the swirling flow is formed in a flow direction in which the wind velocity of the air blown away from the air blower 7c is strong by the air suction device 9 and the two air blowers 7a, that is, near the dust collecting portion 8.

With such a configuration, it is possible to further ventilate the room without affecting the dust collection air flow generated by the air blower.

In addition, the blower operates in cooperation with an air conditioner in the room to generate dust collection air flow.

With such a configuration, the dust collection airflow can be generated with a small amount of air blower, and the dust collection airflow is not disturbed by the air conditioner.

Further, in the blower of the dust collection apparatus according to the second embodiment, among the plurality of blowers, the blower disposed at a position farthest from the dust collection unit has the same air volume as the other blowers and has a slow wind speed It is assumed that the air is blown by the

With such a configuration, the rotational axis of the swirling flow on the floor surface 5a is disposed at a position close to the dust collection portion, whereby the balance of the swirling flow is lost. As a result, since the rotational shaft of the swirling flow is formed at a position close to the dust collection portion, dust can be efficiently collected to the dust collection portion.

Third Embodiment
FIG. 3 shows a plan view of a room provided with a dust collection apparatus according to a third embodiment of the present invention.

Further, furniture 14 is placed inside the room, and a part of the room is substantially divided by the furniture 14.

In each room, a dust collection air flow 12 which is a swirling flow is formed by adjusting the air volume and the air flow direction so as not to cancel the air flow generated by the air blower 7 with each other by the air blower 7. In FIG. 3, the dust collection air flow 12 is composed of three swirling flows according to the shape of the room. Further, the swirling direction of the adjacent swirling flow is reverse rotation.

First, when the dust collecting apparatus is activated, the blower 7 starts blowing air and generates the dust collection air stream 12. Dust in the room is conveyed by the dust collection air flow 12 and collected in the dust collection unit 8.

As shown in FIG. 3, the dust collection air flow 12 is roughly divided into three swirling flows, and the swirling directions of the adjacent swirling flows are reverse rotations so that the air flows of each other do not cancel each other out. It has become.

Then, dust in each room is collected to the dust collection unit 8 by the respective swirling flows. Therefore, dust is collected in the entire room even when dust collection is performed in a room where it is difficult to perform dust collection in a single swirling flow in which the room is substantially divided by a room or furniture that does not have a square shape. Can be collected in one place.

The series of operations of the blower 7 and the adjustment of the air volume and the air direction in the third embodiment are electrically controlled by a control means (not shown).

That is, in the dust collection apparatus of the third embodiment, the blower is configured to perform the blower so as to generate a plurality of swirling flows in the room.

With such a configuration, it is difficult to perform dust collection with a single swirling flow that swirls the entire room, such as a room that is substantially divided by a room that is not a square and furniture that is difficult to collect dust Even in the case of the above, dust collection can be performed efficiently.

The configurations in Embodiments 1 to 3 described above can be used in appropriate combination as needed. Moreover, the structure of the dust collector of this invention is not restricted to the structure of embodiment itself mentioned above.
