Description

  The present invention relates to an indoor dust collector that collects dust while generating an airflow in a room.

  Conventionally, as this type of indoor dust collector, there is one that has a dust collecting part that collects dust while generating airflow in the room, and that collects dust more reliably by changing the airflow ( For example, see Patent Document 1).

  FIG. 4 shows a plan view of the room where the conventional indoor dust collector described in Patent Document 1 is installed.

  In FIG. 4, a conventional indoor dust collector is constituted by a dust collector 1 and an airflow measuring device 2. The dust collecting unit 1 generates an air flow for collecting dust and collects floating dust. The airflow measuring device 2 determines whether or not the floating dust 3 around the airflow measuring device 2 can be collected depending on whether the airflow generated by the dust collecting unit 1 can be detected. Moreover, the airflow measuring device 2 is configured to be able to carry around the room freely. Based on the determination of the airflow measurement device 2, the dust collecting unit 1 changes its operation, and reliably collects the floating dust 3 around the airflow measurement device 2 and cleans the air.

JP 11-193944 A

  However, in the configuration of the conventional indoor dust collector as described in Patent Document 1, it is not possible to reduce the total amount of dust existing in the room by generating a dust collection airflow in the whole room for dust collection. However, for example, it becomes a shadow when viewed from above, such as the interior of furniture or under furniture, and dust will intrude into the non-deposition area where dust does not fall if there is no air flow, and dust will accumulate in the past There was a problem that dust would accumulate in the non-deposited areas that were not.

  In addition, in the conventional indoor dust collector, when there is an air curtain part that generates, for example, a cut-off air current that prevents dust from entering the non-deposition area, in addition to the dust air flow, the mutual air current is generated. It has a problem that dust collection cannot be performed efficiently due to the influence, and that dust cannot be prevented from entering the non-deposition region.

  The present invention solves the above-described conventional problems, and provides an indoor dust collector capable of preventing dust from entering and accumulating in a non-deposition area while maintaining dust collection performance by a dust collection airflow. The purpose is to do.

In order to solve the above-described conventional problems, the indoor dust collector of the present invention includes a dust collecting unit that generates a dust collecting air flow in the entire room and collects floating dust, and a non-deposition region in which dust does not fall if there is no air flow. The air curtain unit is disposed around the air curtain unit to prevent floating dust from entering the non-deposition region by generating a block air flow, and the air curtain unit moves the block air flow in a direction in which the dust collection air flow is not disturbed. By flowing, it is possible to prevent dust from entering the non-deposition area while maintaining the dust collection performance of the floating dust by the dust collection airflow.

  The indoor dust collector of the present invention can prevent dust from entering the non-accumulating region while maintaining the dust collection performance by the dust collection airflow, and thus efficiently collects the floating dust in the entire room. The deposition area can also be reliably kept clean.

  According to a first aspect of the present invention, there is provided a dust collecting portion that generates a dust collecting air flow in the entire room and collects floating dust, and is arranged around a non-deposition area where dust does not fall if there is no air flow, thereby generating a non-destructive air flow. An air curtain portion is provided to prevent the floating dust from entering the accumulation area, and the air curtain portion is configured to flow the blocking airflow in a direction in which the dust collection airflow is not disturbed. It is possible to prevent dust from entering the non-deposition area while maintaining the dust collection performance.

  In the second invention, in particular, the air curtain part of the first invention does not direct the cut-off airflow to the dust collecting part, and the floating dust is collected to the most important dust collecting part in the dust collecting airflow. The dust collection performance can be maintained because it is surely not disturbed.

  According to a third aspect of the invention, in particular, the air curtain part of the first or second aspect of the invention is configured such that a cut-off air current is blown out toward a wall surface or a floor surface. It loses wind speed and spreads around the wall or floor. On the other hand, since the dust collection airflow mainly flows through a large space in the center of the room away from the wall surface or floor surface in the entire room, the cut-off airflow does not disturb the dust collection airflow.

  According to a fourth aspect of the invention, in particular, the air curtain part of any one of the first to third aspects of the invention comprises a blow-out part that blows off a cut-off air flow and a suction part that sucks the cut-off air blown out of the blow-out part. The blowing section predicts a change in the cut-off airflow due to the influence of the dust collection airflow, and changes the wind speed and the wind direction so that the cut-off airflow after the change is directed to the suction section. Since the air flows reliably from the blow-out part to the suction part, the surrounding dust collecting air current is not disturbed.

  According to a fifth aspect of the invention, in particular, the air curtain part of any one of the first to third aspects of the present invention comprises a blow-out part that blows off a cut-off air current and a suction part that sucks the cut-off air current blown from the blow-out part. The suction unit predicts a change in the cutoff airflow due to the influence of the dust collection airflow, and changes the suction strength and direction according to the wind speed and direction when the changed cutoff airflow reaches the suction unit. In this way, the interrupted airflow flows more reliably from the blowing part to the suction part, so that the surrounding dust collecting airflow is not disturbed.

  In the sixth aspect of the invention, in particular, the air curtain part of the first aspect of the invention is installed on the long side of the opening of the non-deposition region, and the cut airflow is made to flow toward the short side of the opening. Therefore, compared with the case where it is arranged on the short side, the distance that the cut-off air flow must reach to prevent the invasion of floating dust is shortened, so that the cut-off air flow can be weakened and the dust collection air flow is not disturbed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
FIG. 1 is a perspective view of a room where an indoor dust collector is installed according to Embodiment 1 of the present invention, and FIG. 2 is a schematic diagram showing an air flow near the floor surface of the room where the indoor dust collector is installed. FIG.

  In FIG. 1, the indoor dust collector in this Embodiment is comprised from the dust collection part 4 installed in the room, and air curtain parts 5A and 5B. A bed 6 is arranged as furniture in the room. The bottom of the bed 6 is a shadow when viewed from above, and is a non-deposition region 7 where dust does not fall if there is no airflow.

  The dust collecting unit 4 sucks air from the entire room and blows air again into the room, thereby generating a dust collecting air flow 8 in the whole room and collecting the floating dust 9.

  In the present embodiment, the two air curtain portions 5A and 5B are arranged around the bed 6, and operate separately to generate the cut-off air currents 10A and 10B, respectively.

  The air curtain portion 5A disposed on the side surface of the bed 6 far from the dust collection portion 4 is provided on the long side of the opening (not shown) of the non-deposition region 7 and has a wide shape. A cut-off air flow 10A is generated. On the other hand, the air curtain part 5B arranged on the side surface close to the dust collecting part 4 of the bed 6 is provided on the short side of the opening, and generates a cut-off air flow 10B in a substantially horizontal direction with respect to the floor surface. Yes. In addition, the air curtain part 5 </ b> B allows the cut-off air flow 10 </ b> B to flow toward the wall surface in the direction opposite to the dust collecting part 4.

  In FIG. 2, a bed 6 is provided in the room, and a lower portion of the bed 6 is a non-deposition region 7.

  In addition, a dust collection part 4 and air curtain parts 5A and 5B are arranged in the room, and a dust collection air flow 8 directed toward the dust collection part 4 is generated near the floor surface of the room. A part of the dust collection airflow 8 is located on the lower side of the bed 6 and on the side far from the dust collection unit 4 where the air curtain unit 5A is disposed on the upstream side, and on one side near the dust collection unit 4 the air curtain unit The side where 5B is disposed flows on the downstream side.

  The operation and action of the indoor dust collector in the present embodiment configured as described above will be described below.

  First, when the indoor dust collector is operated, the dust collection unit 4 generates a dust collection airflow 8 in the entire room. As a result, the dust collection air flow 8 always flows in the non-deposition region 7 (shaded portion) under the bed 6. The floating dust 9 tries to enter the non-deposition region 7 along with the dust collection airflow 8, but here, in the present embodiment, the air curtain portions 5A and 5B are operated.

  The air curtain portion 5A generates a cut-off air flow 10A from the long side of the opening of the non-deposition region 7 toward the floor surface. The cutoff air flow 10A is formed from the long side of the opening so as to prevent the floating dust 9 from entering from the opening of the non-deposition region 7 and reaches the floor surface. This is because the cut airflow 10A can be easily formed because a weak airflow is reached as compared with the case where the airflow is made to reach the other short side.

The cut-off air flow 10A that has reached the floor surface loses wind speed due to the collision with the floor surface and diffuses around the floor surface. On the other hand, since the dust collection air flow 8 mainly flows through a wide space in the center of the room away from the wall surface or floor surface, the diffused cutoff air flow 10A hardly affects the dust collection air flow 8.

  The air curtain part 5 </ b> B generates a cut-off air flow 10 </ b> B from the short side of the opening of the non-deposition region 7 toward the wall surface in the direction opposite to the dust collecting part 4. Similarly to the air curtain portion 5A, the cut-off air flow 10B that has reached the wall surface loses the wind speed due to the collision with the wall surface and diffuses around the wall surface.

  On the other hand, since the dust collection air flow 8 mainly flows through a wide space in the center of the room away from the wall surface or floor surface, the diffused cut air flow 10B hardly affects the dust collection air flow 8.

  When air is blown from the short side opposite to the drawing to the dust collecting unit 4, the shut-off air flow 10B disturbs the dust collecting air flow 8 flowing to the dust collecting unit 4 and reduces the dust collection rate. End up. Further, when air is blown from the long side to the short side as in the case of the air curtain portion 5A, since the position on the floor surface where the blocking air flow 10B collides and diffuses is close to the dust collecting portion 4, the diffused blocking air flow 10B. Will disturb the dust collecting air flow 8.

(Embodiment 2)
FIG. 3 is a schematic diagram showing the airflow near the floor surface in the room where the indoor dust collector in Embodiment 2 of the present invention is installed. In addition, the same code | symbol is attached | subjected to the same part as the indoor dust collector in the said Embodiment 1, and the description is abbreviate | omitted.

  In FIG. 3, a bed 6 is provided in the room, and a lower portion of the bed 6 is a non-deposition region 7.

  In the present embodiment, the air curtain portion 5A disposed on the side surface of the bed 6 far from the dust collection portion 4, that is, the upstream side of the dust collection air flow 8 in the non-deposition region 7 is constituted by the blowout portion 11A and the suction portion 12A. On the other hand, the air curtain portion 5B arranged on the side surface close to the dust collecting portion 4 of the bed 6, that is, on the downstream side of the dust collecting air flow 8 in the non-deposition region 7, is composed of the blowing portion 11B and the suction portion 12B. Other configurations are the same as the indoor dust collector in the first embodiment.

  Each of the blowout portions 11A and 11B has a blower for blowout (not shown) inside, can change the wind speed of the shutoff airflows 10A and 10B, and has a louver 11D at the blowout port 11C at the same time. And the wind direction of the interruption | blocking airflow 10 can be changed. Similarly, the suction units 12A and 12B also have suction fans (not shown) inside, and can change the force for sucking and guiding the cut air flows 10A and 10B, respectively. At the same time, each of the suction ports 12C has a louver 12D, and the direction of sucking and guiding the cut-off airflows 10A and 10B can be changed.

  As described above, different airflows 10A and 10B are generated in the air curtain part 5A placed on the upstream side and the air curtain part 5B placed on the downstream side, respectively.

  The operation and action of the indoor dust collector in the present embodiment configured as described above will be described below.

  First, when the indoor dust collector is operated, the dust collection unit 4 generates a dust collection airflow 8 in the entire room. As a result, the dust collection air flow 8 always flows in the non-deposition region 7 under the bed 6. The air curtain parts 5A and 5B are operated because the floating dust 9 tends to enter the non-deposition area 7 along with the dust collection airflow 8.

  The air curtain unit 5A changes the operation of the blowing unit 11A and the suction unit 12A so that the cut-off air flow 10A blown from the blowing unit 11A flows smoothly to the suction unit 12A. Similarly, the air curtain unit 5B changes the operation of the blowing unit 11B and the suction unit 12B so that the cut-off airflow 10 blown from the blowing unit 11B flows smoothly to the suction unit 12B.

  The cut-off airflows 10 </ b> A and 10 </ b> B blown out from the blowing units 11 </ b> A and 11 </ b> B affect the dust collection airflow 8 flowing under the bed 6, and the wind direction is directed to the downstream side of the dust collection airflow 8. The blowing units 11A and 11B change the blowing wind direction of the cut-off airflows 10A and 10B based on, for example, the operating conditions of the dust collecting unit 4 and the surrounding airflow measured by the blowing units 11A and 11B and the suction units 12A and 12B. .

  As a result, the interrupting airflows 10A and 10B draw a curve and flow through a longer distance to the suction parts 12A and 12B, so that the blowing speeds of the blowing parts 11A and 11B are further increased.

  As the cut-off airflows 10A and 10B change, the suction force and the suction direction are also changed in the suction units 12A and 12B. When there is no dust collection airflow 8, each of the blocking airflows 10A and 10B flows straight from the blowing portions 11A and 11B. However, the blocking airflows 10A and 10B draw a curve and have different angles than before. In order to reach 12A and 12B, the louver 12D of the suction port 12C is adjusted to the angle and the suction direction is changed.

  Moreover, since the wind speed and the air volume of the cut-off airflows 10A and 10B reaching the suction units 12A and 12B also change with the operation change of the blowout units 11A and 11B, the cut-off airflows 10A and 10B that have reached are sucked as they are and cannot be completely sucked. The suction force is adjusted so that the blocking airflows 10A and 10B do not flow to the surroundings, or conversely, the suctioning force is excessively increased and the surrounding air is not sucked excessively. The adjustment of the suction force is performed based on, for example, the operating conditions of the blowing units 11A and 11B, the ambient airflow measured by the blowing units 11A and 11B, and the suction units 12A and 12B.

  As a result of these operations, the strength of the dust collecting airflow 8 is different between the upstream side and the downstream side of the non-deposition region 7, so that the upstream air curtain portion 5A and the downstream air curtain portion 5B are formed. The cutoff airflows 10A and 10B are different.

  The configurations in the above embodiments can be used in appropriate combinations as needed, and the present invention is not limited to the configurations in the above embodiments themselves.

  As described above, the indoor dust collector according to the present invention can prevent dust from entering the non-deposition area while maintaining the dust collection performance by the dust collection airflow. It can be applied to various devices that generate
