(Embodiment 1)
FIG. 1 shows a perspective view of a room provided with the indoor dust collector in Embodiment 1 of the present invention.

  In FIG. 1, a plurality of air blowing means 7 a and 7 b are provided in the room above the wall surface 50 and the wall surface 53 near the indoor ceiling. A dust collecting means 8 is provided at one corner near the floor surface in the room.

  The dust collecting means 8 is configured integrally with the control unit 9 and incorporates air blowing means 7a and 7b and dust detecting means 81 for detecting dust. The dust detection means 81 actually detects the amount of dust in the intake air by irradiating laser light like a particle counter used in a clean room or the like and recognizing the level of scattered light due to dust. The controller 9 controls the dust collecting means 8 and the air blowing means 7a and 7b based on the output of the dust detecting means 81. The air blowing means 7a, 7b and the dust collecting means 8 constitute an indoor dust collecting device.

  FIG. 2 shows a block diagram of the indoor dust collector of Embodiment 1 of the present invention.

  As shown in FIG. 2, the dust collecting means 8 includes a dust detecting means 81, a first infrared communication part 82, a control part 9, a first air blowing part 83, a dust collecting filter 84, an intake guide 85, an exhaust guide 86, and direction control. The control unit 9 controls the first air blowing unit 83 based on the output of the dust detection unit 81, and intake is performed from the outside of the dust collection unit 8 through the dust collection filter 84 and the intake guide 85. At this time, dust is collected by the dust collection filter 84. Further, the air that has been sucked in and dust has been filtered by the dust collection filter 84 is discharged into the room through the direction control unit 87 and the exhaust guide 86.

  The direction control unit 87 has a so-called louver shape and changes its inclination angle according to an instruction from the control unit 9 to change the direction of the exhaust air. In addition, the control unit 9 transmits a control signal to the blowing unit 7 by infrared light through the first infrared communication unit 82. The blower means 7 includes a second infrared communication unit 71, a blower control unit 72, and a second blower unit 73. The blower control unit 72 receives a control signal from the control unit 9 through the second infrared communication unit 71, and performs control. The 2nd ventilation part 73 is controlled according to a signal, and the wind volume and the wind direction of the wind which the 2nd ventilation part 73 generate | occur | produces (The detail of the change of an air volume and a wind direction is not shown in figure).

  About the dust collector comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 3 shows an operation flow of the indoor dust collector of the present invention.

  First, when the dust collecting means 8 of the dust collecting device is activated, the dust detecting means 81 starts detecting dust floating in the room (step 1). When dust is detected by the dust detection means 81, the control section 9 transmits a control signal to the blower means 7a through the first infrared communication section 82 and starts the operation of the first blower section 83. The outside air is inhaled. Furthermore, the control part 72 of the ventilation means 7a receives the control signal from the control part 9 through the 2nd communication part 71, controls the 2nd ventilation part 73, and starts ventilation from the 2nd ventilation part 73 (step 2).

  Similarly, the blower 7b starts blowing in response to an instruction from the control unit 9.

  Here, the installation position and the wind direction of the dust collection airflow 10 and the air blowing means 7a and 7b will be described.

  In the dust collecting air flow 10, the wind exhausted upward from the dust collecting means 8 hits the ceiling, and then flows along the ceiling to the wall facing the dust collecting means 8 in the room, where it hits the wall and descends toward the floor, Thereafter, the flow circulates in the room toward the dust collecting means 8 along the floor.

  The air blowing means 7a is installed in the vicinity of the ceiling of the wall surface 50 in the room so as to assist in flowing along the ceiling of the dust collecting air flow 10, and blows air from the back side in FIG. In addition, the air blowing means 7b spreads the exhaust air from the dust collecting means 8 throughout the room, and its own air blows against the wall surface 50, descends toward the floor along the wall surface 50, and then moves along the floor to the dust collecting means 8. The air is blown toward the right side (in the direction of the wall surface 50) of the dust collecting means 8 in FIG.

  The flow of the dust collection airflow 10 circulating in the room varies depending on the exhaust airflow amount and the wind direction of the dust collection means 8 and the blown airflow amount and the wind direction of the blower means 7. Therefore, the control unit 9 performs control while switching the exhaust air volume and the wind direction of the dust collecting means 8 and the air flow rate and the air direction of the air blowing means 7 in a plurality of patterns every predetermined time so that the dust collecting air flow 10 flows through the entire room. For example, the operating conditions when the exhaust air volume of the dust collecting means 8 is large, the wind direction is directly above, the air volume of the air blowing means 7a is small, the air direction is parallel to the wall surface 50, the air volume of the air blowing means 7b is small, and the air direction is the wall surface 50 direction are pattern A. Then, in the pattern A, the dust collection air flow 10a flowing on the left side of the room in FIG. Further, when the exhaust air volume of the dust collecting means 8 is large, the wind direction is substantially right (the direction of the wall surface 50), the air volume of the air blowing means 7a is large, the air direction is parallel to the wall surface 50, the air volume of the air blowing means 7b is large, and the air direction is the wall surface 50 direction. Assuming that the operating condition is pattern B, in pattern B, dust collection air flow 10b flowing on the right side from the center of the room in FIG.

  These air blowing patterns are such that the air flow generated by the air blowing means 7 and the air flow of the dust collecting means 8 do not weaken or cancel each other at the place where the air blowing means 7a and 7b are installed, and the dust collecting air flow 10 is not in the entire room. The size of the room and the layout information of the furniture are set in advance.

  As a result, a circulating airflow flowing through the entire room is formed by the airflow control of the dust collector 8 and the air blowing means 7 by the control unit 9.

  Subsequently, in the operation flow of FIG. 3, when a predetermined time (for example, 1 minute) set in advance has elapsed (step 3), the control unit 9 controls the exhaust air volume of the dust collecting means 8, the wind direction, and the blown air volume of the air blowing means 7, The wind direction is changed (step 4). When a predetermined time (for example, 1 minute) has elapsed (step 3), the control unit 9 confirms the detection state of the dust detection means 81 (step 6), and returns to step 2 if dust is detected. Then, the exhaust air volume and the wind direction of the dust collecting means 8 and the blow air volume and the air direction of the air blowing means 7 are changed again (step 2).

  That is, after the dust collecting air flow 10 is generated by the air blowing means 7a and 7b and the dust collecting means 8, the control unit 9 performs the exhaust air flow rate, the wind direction and the air blowing means 7 by the control unit 9 every predetermined time while the dust is detected. The air flow rate and the wind direction are changed so that the dust collection airflow 10 flows through the entire room.

  If no floating dust is detected in step 6, it is determined whether or not a predetermined time (for example, 2 minutes) has elapsed since that time (step 7). When the predetermined time has elapsed, the air blowing means 7a and 7b and the dust collecting means 8 are stopped (step 5). Then, the process returns to the first step 1 for waiting for detection of floating dust.

As described above, in the present embodiment, the dust detection means 81 incorporated in the dust collection means 8 detects dust floating in the room, so that the dust collection means 8 and the air blowing means 7a and 7b are operated in cooperation. Is started, and while the dust is detected, the dust collecting means 8 and the air volume and direction of the air blowing means 7a and 7b are changed every predetermined time to generate a dust collecting airflow 10 that circulates and flows through the entire room, It becomes possible to efficiently collect floating dust.

  In the present embodiment, it is assumed that the air blowing means 7 and the dust collecting device 8 are composed of one unit, but this can be appropriately selected according to necessity, such as the size and shape of the room, and the installation location. The configuration is not limited to the configuration of the embodiment itself.

  Furthermore, in the present embodiment, the dust collector is configured to form only two patterns of the dust collecting air flow 10, but the air volume and the wind direction of the air blowing means 7 and the dust collecting means 8 are adjusted to be different dust collecting air flows 10. Alternatively, the switching may be performed in a pattern that is regularly or temporally biased to change the circulation flow of the dust collection airflow 10 in the room to increase the dust collection efficiency.

  Furthermore, the air volume and the air direction are set so that the air currents of the air blowing means 7 and the dust collector 8 do not cancel each other out. However, these air currents are positively collided and collected based on the air currents generated thereby. The dust airflow 10 may be formed so as to flow in various places in the room.

  In the first embodiment, the control signal is transmitted and received by infrared light. However, the present invention is not limited to this structure, and wireless communication using radio waves instead of infrared light may be used. Similar effects can be obtained.

(Embodiment 2)
FIG. 4 shows a perspective view of the room provided with the indoor dust collector in Embodiment 2 of the present invention.

  In FIG. 4, the air conditioner 11 is provided near the ceiling of the wall surface 51 in the room.

  The air conditioner 11 is a so-called air conditioner that can change the wind direction up and down and left and right by a louver. As in the first embodiment, dust collecting means 8 is provided at one corner near the floor surface in the room.

  The dust collection means 8 is different in that the direction control unit 87 can change the inclination angle of the louver in the left-right direction to change the wind direction not only up and down but also in the left-right direction. Since other parts are the same as those in the first embodiment, description thereof is omitted.

  The control unit 9 transmits a control signal to the air conditioner 11 by infrared light through the first infrared communication unit 82.

  The first infrared communication unit 82 transmits signals using infrared light as described above, and has a function of a so-called learning-type remote controller that stores the signal pattern of the infrared remote controller, and is previously air-conditioned in the room. By storing the signal pattern of the device 11, the air volume and the air direction (louver direction control) of the air conditioner 11 can be controlled from the dust collecting means 8. The air conditioner 11 receives a control signal from the control unit 9 through the remote control light receiving unit, and changes the air flow rate and direction according to the control signal.

  Moreover, the 1st infrared communication part 82 can perform the cooperation with the other air-conditioning equipment which uses the existing infrared remote control by transmitting information using infrared light.

  About the dust collector comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 5 shows an operation flow of the indoor dust collector of the present invention.

  First, when the dust collecting means 8 of the dust collecting device is activated, the dust detecting means 81 starts detecting dust floating in the room (step 11). When dust is detected by the dust detection means 81, the control section 9 transmits a control signal to the air conditioner 11 through the first infrared communication section 82 and starts the operation of the first blower section 83, and the dust collection means 8. The outside air is inhaled. Further, the air conditioner 11 starts blowing with the air volume and the air direction instructed based on the control signal from the control unit 9 (step 12).

  Here, the airflow blown from the dust collection airflow 10, the air conditioner 11, and the dust collection means 8 will be described.

  6 and 7 are a side view and a top view, as seen from the side, of the indoor space for explaining the state of the dust collecting airflow 10 formed by the air conditioner 11 and the dust collecting means 8. In FIG. 6, when the air direction of the air conditioner 11 is downward in the floor direction and the wind direction of the dust collecting means 8 is directly above the ceiling direction, the air flow blown downward from the air conditioner 11 is sucked by the dust collecting means 8 and collected. The wind exhausted from the dust means 8 to the upper part of the room hits the ceiling, and then flows along the ceiling toward the air conditioner 11 to become a dust collection air flow 10c circulating in the room.

  7A shows the airflow direction of the air conditioner 11 in the right direction when viewed from the air conditioner 11 (in the direction of the wall 51 in FIG. 7A), and the airflow direction of the dust collection means 8 as seen from the dust collection means 8 is rightward (see FIG. 7). (The wall surface 53 direction of (a)) (the vertical direction is downward) The airflow blown rightward from the air conditioner 11 is sucked into the dust collecting means 8 and exhausted rightward from the dust collecting means 8. It becomes the dust-collecting airflow 10f that merges with the airflow and hits the wall surface 53 in the room and then flows along the wall surface 53 toward the air conditioner 11 and circulates in the room.

  7B shows the airflow direction of the air conditioner 11 in the left direction when viewed from the air conditioner 11 (the direction of the wall 53 in FIG. 7B), and the air direction of the dust collecting means 8 is leftward when viewed from the dust collection means 8. 7 (b), the airflow blown to the left from the air conditioner 11 hits the wall surface 53, flows along the wall surface 53 and is sucked by the dust collecting means 8, and from the dust collecting means 8. The air that has been exhausted to the left merges, hits the wall surface 51 in the room, and then flows along the wall surface 51 toward the air conditioner 11 and becomes a dust collection airflow 10g that circulates in the room.

  When the airflow as described above is viewed throughout the room, the control unit 9 of the dust collecting means 8 controls the air blowing direction of the air conditioner 11 and the dust collecting means 8 simultaneously in the horizontal and vertical directions. The operation condition when the horizontal direction is the right, the wind direction of the dust collecting means 8 is the vertical upward direction, and the horizontal right direction is the pattern c. In the case of pattern c, the combined dust collection airflow 10 shown in FIGS. 6 and 7A is obtained, and an airflow that circulates in the room tilted to the right when viewed from the front of FIG. 4 like the dust collection airflow 10h shown in FIG. It becomes.

  On the other hand, an operation condition when the airflow direction of the air conditioner 11 is vertically downward and horizontal leftward, and the wind direction of the dust collecting means 8 is vertically upward and horizontal leftward is a pattern d. In the case of pattern d, a combined dust collection airflow 10 shown in FIGS. 6 and 7B is obtained, and an airflow that circulates in the room tilted to the left when viewed from the front of FIG. 8 as in the dust collection airflow 10j shown in FIG. It becomes.

Subsequently, in the operation flow of FIG. 5, when a predetermined time (for example, 1 minute) elapses (step 13), the control unit 9 changes the exhaust direction of the dust collecting means 8 and the blowing air direction of the blowing means 7 ( Change to operation instruction pattern d) (step 14). When a predetermined time (for example, 1 minute) has elapsed (step 13), the control unit 9 confirms the detection state of the dust detection means 81 (step 16), and returns to step 12 if dust is detected. Then, the exhaust direction of the dust collecting means 8 and the blowing air direction of the blowing means 7 are changed again (step 12). That is, after the dust collecting air flow 10 is generated by the air blowing means 7a and 7b and the dust collecting means 8, the control unit 9 performs the exhaust direction of the dust collecting means 8 and the air blowing of the air blowing means 7 every predetermined time while the dust is detected. The wind direction is changed.
If no floating dust is detected in step 16, it is determined whether or not a predetermined time (for example, 2 minutes) has elapsed since that time (step 17). When the predetermined time elapses, the air blowing means 7a and 7b and the dust collecting means 8 are stopped (step 15). Then, the process returns to the first step 1 for waiting for detection of floating dust.

  As described above, in the present embodiment, the dust detection unit 81 incorporated in the dust collection unit 8 detects dust floating in the room, and the operation of the dust collection unit 8 and the air conditioner 11 is started. While the dust is detected, the wind direction of the dust collecting means 8 and the air conditioner 11 is changed every predetermined time, thereby generating a dust collecting air flow 10 that circulates the entire room, and efficiently floating the dust. It becomes possible to collect dust.

  In the present embodiment, one dust collector 8 is used, and the indoor air conditioner 11 is used as the blowing means 7 and no other blowing means is used. However, this is necessary for the size and shape of the room. However, the present invention is not limited to the configuration of the embodiment itself.

  Further, although only the air direction of the air conditioner 11 and the dust collecting means 8 is changed, the air volume may be changed as appropriate. For example, the airflow is gradually increased within a predetermined time, and after reaching the maximum, the airflow is also changed so as to gradually decrease the airflow, so that the state of the dust collection airflow 10 flowing in the room changes, and the airflow flowing through the entire room is further increased. A dust stream can be formed.

A position recognizing means 26 for calculating and recording the movement trajectory of the automatic mobile cleaner body 21; a buffer means 28 for detecting contact with an obstacle installed in front of the automatic mobile cleaner body 21; A time measuring means 32 for measuring time such as an elapsed time from the electric power; a setting input means 31 for a user to input an instruction to start and stop the automatic mobile vacuum cleaner body 21 or change various settings; An object detection unit 22, a direction detection unit 23, a distance recognition unit 24, a position recognition unit 26, a buffer unit 28, a setting input unit 31, and a control unit 25 that controls the travel unit 27 in response to the output of the time measuring unit 32. ing.

  The direction detecting means 23 is constituted by a gyro sensor that outputs a signal proportional to the angular velocity, and a circuit that integrates the output signal of the gyro sensor and converts it into an angle.

  The automatic mobile vacuum cleaner main body 21 includes an infrared light transmission unit (not shown), and the second infrared communication unit 71 of the blowing unit 7 or the first infrared communication unit 82 of the dust collection unit 8. Information and control signals are exchanged using infrared light.

  About the dust collector comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the dust collecting means 8 of the dust collector is activated, the dust detecting means 81 starts detecting dust floating in the room. When dust is detected, the control of the dust collecting means 8 is performed as in the first embodiment. The air blowing means 7a, 7b and the dust collecting means 8 are blown by the control signal from the section 9 to form dust collecting airflows 10a, 10b circulating in the room. The dust collected in the room is transported by the dust collecting airflows 10 a and 10 b and collected by the dust collecting means 8. After the dust detection unit 81 stops detecting dust and the air blowing unit 7 and the dust collecting unit 8 operate for a predetermined time (for example, 2 minutes), the control unit 9 stops the air blowing unit 7 and the dust collecting unit 8.

  The control unit 9 further transmits information and a control signal using infrared light from the first infrared communication unit 82 after a predetermined time has elapsed from the predetermined time (5 minutes), and the automatic mobile vacuum cleaner main body 21 is red. By receiving it with an external light transmission unit (not shown), the automatic mobile vacuum cleaner main body 21 starts its operation and cleans the indoor floor surface. Here, the operation of the automatic mobile vacuum cleaner main body 21 will be described.

  After the automatic mobile vacuum cleaner main body 21 is activated, the automatic mobile vacuum cleaner main body 21 starts moving forward, and an obstacle is detected within a predetermined distance (for example, 10 cm) by the obstacle detection means 22 in front of the automatic mobile vacuum cleaner main body 21. When detected, the control unit 5 controls the traveling means 7 to stop the automatic mobile vacuum cleaner main body 21 and perform random angular rotation (for example, 90 degrees to the left). At this time, the control unit 5 reversely rotates the left and right driving wheels 9 by the traveling means 7 while monitoring the rotation angle of the main body 1 by the direction output of the direction detecting means 3 (the left driving wheel moves backward and the right driving wheel moves forward). As a result, the main body 1 is rotated 90 degrees to the left (counterclockwise). After the rotation is completed, the vehicle starts moving forward again and continues straight ahead of the automatic mobile vacuum cleaner main body 21 until the obstacle detection means 22 detects the obstacle. Thereafter, while repeating this operation, cleaning is performed for a preset time based on the size of the room.

  The automatic mobile vacuum cleaner main body 21 can remove dust having a heavy weight such as sand accumulated on the floor without being able to get on the dust collecting air flow 10 by cleaning the floor in the room.

  As described above, in the present embodiment, the dust collection airflow 12 becomes the dust collection airflows 10a and 10b circulating in the room, and the dust floating in the dust collection means 8 can be efficiently collected. Further, dust having a heavy weight such as sand accumulated on the floor surface without being able to get on the dust collecting air flow 10 can be removed by the automatic mobile vacuum cleaner main body 21.

  In the present embodiment, the automatic mobile vacuum cleaner body 21 starts the automatic mobile vacuum cleaner body 21 every time after a certain period of time has elapsed after the air blowing means 7 and the dust collecting means 8 are stopped. When the automatic movement cleaner body 21 is activated every predetermined operating time of the dust collecting means 8 (for example, every time the air blowing means 7 and the dust collecting means 8 are operated for 3 hours), the same effect can be obtained. At the same time, the power consumption of the entire apparatus can be suppressed.

  In the present embodiment, the automatic mobile vacuum cleaner main body 21 and the dust collecting means 8 are provided. However, the present invention is not limited to this configuration. The dust collector 8 and the automatic mobile vacuum cleaner main body 21 are integrated. The dust that is formed and floated in the above and heavy dust may be collected by the automatic mobile vacuum cleaner main body 21.

FIG. 11 is an explanatory diagram of an indoor map stored in the position recognition means 26 of the automatic mobile vacuum cleaner main body 21 according to Embodiment 4 of the present invention. FIG. 12 is a perspective view of the room to which a cleaning priority area of the indoor dust collector in Embodiment 3 of the present invention is added.

  The fourth embodiment is different only in the operation of the self-propelled cleaning main body 21, and the main body configuration is the same as that of the third embodiment.

  The position recognizing means 6 includes the position information of the main body 21 calculated from the rotation angle (moving direction) of the main body 21 detected by the direction detecting means 3 of the main body 1 and the moving distance of the main body 1 detected by the distance recognizing means 4. The movement trajectory is stored on two-dimensional map coordinates as shown in FIG.

  The coordinates in FIG. 11 are defined such that the coordinates increase as the X and Y axes move to the left and upward, respectively, and one coordinate is approximately the same as the width of the main body 21 (for example, 30 cm). In the present embodiment, it is assumed that the uppermost Y coordinate value in the movement region shown in FIG. The correspondence with FIG. 12 is that the right end corner of the room near the automatic mobile vacuum cleaner 21 in FIG. 12 is the P0 point, the corner of the room where the dust collecting means 8 is installed is the P2 point in FIG. The location of the corner (the diagonal position of the corner where the dust collecting means 8 is placed) is the point P1 in FIG.

  In addition, arrangement information of furniture such as indoor chiffons is also input in advance. As in the third embodiment, the control unit 9 forms dust collection airflows 10a and 10b by the airflow control of the dust collection means 8 and the airflow means 7a and 7b, and further the dust collection airflow 10a, The location where the air volume is low or the puddle location of 10b is stored in advance in the position recognition means 26 together with the map in which the indoor shape is recorded (priority areas A and B in FIG. 11).

The operation and action will be described below.
As in the third embodiment, the automatic mobile vacuum cleaner main body 21 does not detect the dust by the dust detection means 81 and is activated by the control unit 9 of the dust collection means 8 after a predetermined time has elapsed. The important area as shown in FIG. 11 is cleaned from the indoor two-dimensional map.

  That is, after starting, the control unit 25 controls the traveling means 27 to move from the point P0 to the priority area A (area starting from the coordinates (4, 2)) based on the map information. And move to the priority area B (area starting from the coordinates (8, 5)) for cleaning.

  As described above, in the present embodiment, the automatic mobile vacuum cleaner main body 21 cleans the floor surface of the indoor important area, so that it does not get on the dust collection airflow 10 circulating in the room and accumulates on the floor surface. It is possible to remove the heavy dust and the dust that has settled at the place where the dust collection airflow 10 is weak.

  The configuration in each of the first to fourth embodiments described above can be used in appropriate combination as necessary, and is not limited to the configuration of the embodiment itself.
