Therefore, the dust collecting box is configured so that the dust collecting filter can be attached and detached.

Japanese Unexamined Patent Publication No. 2009-15611

By the way, the dust collecting filter may be removed when cleaning or maintaining the dust collecting box. In order to prevent the dust collection box from being attached to the cleaning device when the dust collection filter is not attached, conventionally, the cleaning device has a detection mechanism for detecting whether or not the dust collection filter is attached. Is provided. The detection mechanism is known to include, for example, a detector that displaces when the dust collecting filter is mounted and does not displace when the dust collecting filter is not mounted, and a switch unit that detects the displacement of the detector. ing. However, when the dust collecting filter is made of a soft material, even if the dust collecting filter is attached, the detector in contact with the dust collecting filter may not be displaced and may not be detected by the switch unit. is there.

An object of the present invention is to provide a dust collector capable of reliably detecting the presence or absence of a dust collection filter in a dust collection accommodating portion, and a cleaning device including the dust collector.

(1) The dust collector according to one aspect of the present invention includes a dust collection accommodating unit, a dust collection filter, a sensor unit, and a member to be detected. The dust collecting accommodating portion is supported by a predetermined mounting portion. The dust collecting filter is detachably provided in the filter accommodating portion in the dust collecting accommodating portion, and has a flexible material that is deformed by receiving a pressing force. The sensor unit has a displacement member that is displaced by receiving an operating force, and operates in response to the displacement of the displacement member. The detected member is provided in the filter accommodating portion so as to be displaceable. The detected member is arranged at a first position where the acting force can be applied to the displacement member in the first mounted state in which the dust collecting filter is mounted in the filter accommodating portion. Further, the detected member is displaced between the first position and a second position separated from the first position and retractable from the displacement member in a non-mounted state in which the dust collecting filter is not mounted. It is freely configured.

With such a configuration, when the dust collecting accommodating portion is attached to the mounting portion in the first mounting state in which the dust collecting filter is attached to the filter accommodating portion, the detected member comes into contact with the displacement member. As a result, a pressing force in the mounting direction from the detected member to the displacement member is applied to the displacement member as an operating force for displace the displacement member. As a result, the sensor unit operates according to the displacement of the displacement member. This makes it possible to reliably detect the presence or absence of the dust collection filter in the dust collection accommodating portion.

(2) The dust collecting accommodating portion is configured to be removable from the mounting portion. When the dust collecting filter is in the first mounting state and the dust collecting accommodating portion is mounted on the mounting portion, the detected member uses the pressing force in the mounting direction on the mounting portion as the operating force. It is applied to the displacement member. Further, in the detected member, when the dust collecting filter is not mounted and the dust collecting accommodating portion is mounted on the mounted portion, the displacement member pushes the dust collecting member toward the second position in the retracting direction. It receives pressure and is displaced to the second position.

Since it is configured in this way, it is possible to reliably detect the presence or absence of a dust collecting filter in the dust collecting accommodating portion even in a dust collecting device in which the dust collecting accommodating portion is detachably attached to the mounting portion. is there.

(3) The dust collecting accommodating portion has an opening for sending an air flow from the filter accommodating portion to the mounting portion side in the second mounting state in which the dust collecting accommodating portion is mounted on the mounting portion. The displacement member projects outward from the mounting portion. Further, in the second mounting state, the first position of the detected member is a position capable of contacting the protruding end portion of the displacement member, and the second position is a direction away from the protruding end portion. It is a position separated by.

(4) The detected member has an extending portion extending from the back surface of the edge portion of the opening toward the center of the opening at the first position. When the dust collecting filter is in the first mounting state, the extending portion abuts on the protruding end portion of the displacement member to apply a pressing force in the mounting direction to the displacement member. Further, in the unmounted state of the dust collecting filter, the extending portion receives a pressing force in the retracting direction from the displacement member and is displaced to the second position.

(5) The detected member is a plate-shaped member having a ventilation portion for passing the air flow through the opening and covering the opening from the inside of the filter accommodating portion at the first position. Further, the lower end portion of the detected member is supported on the back surface of the lower edge portion of the opening. Further, the extending portion extends downward from the upper end portion of the detected member.

As a result, it is possible to specifically realize a configuration in which the member to be detected is displaced between the first position and the second position.

(6) The detected member may be supported so as to be slidable between the first position and the second position inside the filter accommodating portion.

(7) One end of the detected member may be rotatably supported inside the filter accommodating portion, and the extending portion may be provided at the other end of the detected member.

Even with this configuration, the detected member can be displaced between the first position and the second position.

(8) The sensor unit has a switch unit that operates according to the displacement of the displacement member. The displacement member is rotatably supported by the mounting portion, extends from the center of rotation, receives the operating force from the member to be detected, and extends from the center of rotation to operate the switch portion. It has a detector and. In such a configuration, the present invention is suitable.

(9) The cleaning device according to another aspect of the present invention includes each of the above-mentioned dust collectors.

According to the present invention, it is possible to reliably detect the presence or absence of a dust collecting filter in the dust collecting accommodating portion.

[Filter detection mechanism 50]
FIG. 4 is a schematic diagram showing the configuration of the filter detection mechanism 50. The filter detection mechanism 50 is used for determining the presence or absence of the dust collecting filter 80 mounted in the collection box 16, and is a rotatably supported rotating member 51 (an example of the displacement member of the present invention). It operates according to the displacement. As shown in FIG. 4, the filter detection mechanism 50 is fixed to an internal frame of the apparatus main body 11, specifically, an internal frame of the support holder 17, and has a rotating member 51 and a switch portion 52 (the present invention). An example of a switch unit) and an elastic member 53.

Specifically, the switch unit 52 is a limit switch. The switch unit 52 operates in response to the rotation (displacement) of the rotating member 51. The switch unit 52 includes a switch main body 521 having a built-in contact, an actuator 522 that transmits an external force to the switch main body 521, and a plunger 523 that operates the contact of the switch main body 521 in response to the operation of the actuator 522. The switch unit 52 is connected to the control unit 40, and the control unit 40 determines that the dust collection filter 80 is mounted on the collection box 16 by receiving a detection signal indicating that the switch unit 52 has been activated. To do. On the other hand, when the detection signal is not received, the control unit 40 determines that the dust collection filter 80 is not attached to the collection box 16.

The switch unit 52 is not limited to a mechanical switch such as a limit switch. For example, the switch unit 52 may be a reflective or transmissive photo interrupter. When the switch unit 52 is a reflection type photo interrupter, the second detector 512 of the rotating member 51 is arranged at a reflection position where the light emitted from the light emitting element is reflected and deflected to the light receiving element. The switch unit 52 operates to output the detection signal. When the switch unit 52 is a transmissive photointerruptor, the switch unit 52 operates when the second detector 512 of the rotating member 51 is arranged in the detection region from the light emitting element to the light receiving element. The detection signal is output.

As shown in FIG. 4, the rotating member 51 is rotatably supported by a frame (not shown) inside the support holder 17. The rotating member 51 is displaced according to the fact that the collection box 16 to which the dust collecting filter 80 is mounted is mounted on the box mounting portion 171 of the support holder 17. Specifically, the rotating member 51 is arranged at an undetected position (position shown in FIG. 4) when the collection box 16 is not mounted on the box mounting portion 171. Further, even when the collection box 16 to which the dust collecting filter 80 is not mounted is mounted on the box mounting portion 171, the rotating member 51 is arranged at the undetected position. On the other hand, when the collection box 16 to which the dust collecting filter 80 is mounted is mounted on the box mounting portion 171, the detected member 90 (see FIG. 7) described later is attached to the rotating member 51 during the mounting process of the collection box 16. By abutting and pressing, the rotating member 51 that has received the pressing force rotates and is displaced in the rotation direction D11 from the undetected position to the detected position (position shown in FIG. 6), and is arranged at the detected position. Will be done. In the present embodiment, when the rotating member 51 is arranged at the detection position, the rotating member 51 operates the actuator 522 of the switch unit 52 to operate the switch unit 52.

The rotating member 51 includes a support shaft 510, a first detector 511 (an example of the first detector of the present invention), and a second detector 512 (an example of the second detector of the present invention).

The rotating member 51 is formed in a long arm shape, and a support shaft 510 extending in the same direction as the width direction (horizontal direction D3) of the apparatus main body 11 is provided at a substantially center in the longitudinal direction thereof. The support shaft 510 is rotatably supported by a shaft hole (not shown) provided in the frame of the support holder 17. As a result, the rotating member 51 can rotate between the undetected position and the detected position with the support shaft 510 as the center of rotation.

The first detector 511 extends obliquely backward and downward from the support shaft 510. In other words, the first detector 511 extends obliquely downward from the support shaft 510 toward the front side wall 173 side of the box mounting portion 171. Specifically, the first detector 511 penetrates the through window 174 formed in the front side wall 173 rearward, and the contact portion 515 (protruding end portion) at the tip thereof reaches the internal space of the box mounting portion 171. Has reached. That is, in the state where the rotating member 51 is in the undetected position, the first detector 511 protrudes rearward and outward from the front side wall 173 of the box mounting portion 171. Therefore, when the collection box 16 is mounted on the box mounting portion 171 while the rotating member 51 is in the undetected position, the contact portion 515 is transferred from the detected member 90 (see FIG. 7) described later. Receives pressing pressure. That is, the contact portion 515 is arranged at a position where the collection box 16 can come into contact with the detection portion 95 (see FIG. 8) of the detected member 90, which will be described later, in the process of mounting the collection box 16 on the box mounting portion 171.

The second detector 512 extends forward from the support shaft 510. When the rotating member 51 rotates in the rotation direction D11, the second detector 512 is a portion that operates the switch unit 52 at the detection position. A pressing portion 516 for pressing the head portion of the actuator 522 is provided at the tip of the second detector 512. A stopper 518 is provided below the second detector 512. As a result, the rotating member 51 is restricted from rotating in the rotation direction D12 opposite to the rotation direction D11.

The elastic member 53 is provided on the support shaft 510. The elastic member 53 is, for example, a torsion coil spring. When the rotating member 51 is urged toward the rotation direction D12 by the elastic member 53 and no other external force is acting on the rotating member 51, the second detector 512 hits the stopper 518 of the rotating member 51. It is held in the undetected position where it touches. The elastic member 53 is not limited to the torsion coil spring, and may be a coil spring or the like that urges the second detector 512 of the rotating member 51 toward the stopper 518.

Since the filter detection mechanism 50 is configured in this way, as shown in FIG. 5, when the bottom of the collection box 16 is placed on the bottom plate 172 of the box mounting portion 171 and then the collection box 16 is pushed forward, it is covered. The detection unit 95 (see FIG. 8) of the detection member 90 comes into contact with the contact portion 515 of the rotating member 51. As a result, the rotating member 51 rotates toward the rotation direction D11, the pressing portion 516 of the second detector 512 presses the actuator 522, and the switch portion 52 operates.

[Collection Box 16]
FIG. 7 is a perspective view showing the configuration of the collection box 16. FIG. 8 is a diagram showing a cross-sectional structure of the upper part of the collection box 16.

The collection box 16 collects dust and other debris (suctioned material) sucked from the intake nozzle 18 (see FIG. 2), and is formed in a box shape having a cavity inside. As shown in FIG. 7, the collection box 16 is formed in a thin rectangular shape in the front-rear direction D2. A suction port 61 for guiding the air sucked from the intake nozzle 18 to the inside is formed in the bottom portion 161 of the collection box 16.

As shown in FIG. 8, a filter accommodating portion 65 is provided on the upper side inside the collection box 16. The filter accommodating portion 65 is provided with a dust collecting filter 80 (an example of the dust collecting filter of the present invention) and a detected member 90 (an example of the detected member of the present invention). In the filter accommodating portion 65, the space in the front-rear direction D2 is partitioned by the front side wall 162 and the middle plate 163 separated rearward from the front side wall 162, and the space in the left-right direction D3 is divided by the side walls of the collection box 16 in the left-right direction D3. The space is partitioned, and the space in the vertical direction D1 is partitioned by the bottom plate 165 from the front side wall 162 to the middle plate 163 and the upper side wall of the collection box 16.

An opening 62 is formed in the front side wall 162 forming the wall surface on the front side of the filter accommodating portion 65. The opening 62 is for sending an air flow from the filter accommodating portion 65 toward the external intake port 155 in the box-mounted state (an example of the second mounting state of the present invention) in which the collection box 16 is mounted on the box mounting portion 171. It is a through opening of. In the box-mounted state, the opening 62 is connected to the intake port 155 (see FIG. 2). Further, the opening 62 is also a through opening for allowing the first detector 511 of the rotating member 51 to enter the inside of the filter accommodating portion 65 in the box-mounted state.

When air is sucked from the intake nozzle 18 by the intake fan 151, the air flow enters the inside of the collection box 16 from the suction port 61, advances upward through the collection box 16, and collects dust from the ventilation port 67 of the filter accommodating portion 65. It passes through the filter 80 and flows into the intake port 155 through the opening 62. Then, when passing through the dust collection filter 80, dust, dust, and the like are removed.

FIG. 9 is a perspective view schematically showing the configurations of the dust collecting filter 80 and the member to be detected 90. As shown in FIG. 9, the dust collecting filter 80 includes a flexible sponge-like holding member 81 (an example of the flexible material of the present invention) formed in a rectangular parallelepiped shape corresponding to the internal space of the filter accommodating portion 65, and a sheet. It has an air filter 82 in the shape of a shape. The holding member 81 is for holding the air filter 82. The holding member 81 is a porous soft member having innumerable holes inside, and is a material that easily deforms when a pressing force is received from the outside. For example, a urethane sponge (soft urethane foam) that is easily dented by the pressing force. ). An air filter 82 is wound around the holding member 81. As the air filter 82, for example, a polyester non-woven fabric, a metal mesh filter, a HEPA filter, a ULPA filter, or the like can be applied.

In the present embodiment, the dust collecting filter 80 can be attached to and detached from the filter accommodating portion 65 through the vent 91 and the opening 62. For example, the user can remove the dust filter 80 made of a soft material from the vent 91 and the opening 62 by compressing it. Further, the user can mount the dust collecting filter 80 in a compressed state from the opening 62 and the vent 91 inside the filter accommodating portion 65.

The detected member 90 is provided inside the filter accommodating portion 65 so as to be displaceable in the front-rear direction D2. The detected member 90 is placed in a predetermined first position (position shown in FIG. 8) in a filter mounted state (an example of the first mounted state of the present invention) in which the dust collecting filter 80 is mounted on the filter accommodating portion 65. Be placed. Here, in the first position, when the collection box 16 is mounted on the box mounting portion 171 in the filter mounted state, the detected member 90 comes into contact with the contact portion 515 of the rotating member 51, and the detected member 90 is contacted. It is a position where an operating force in the rotation direction D11 can be applied to the contact portion 515. In the present embodiment, the detected member 90 has the first position and the second position separated rearward from the first position in a state where the dust collecting filter 80 is not mounted on the filter accommodating portion 65 and the filter is not mounted. It is freely displaceable with (the position shown by the broken line in FIG. 8). Here, in the second position, even when the collection box 16 is mounted on the box mounting portion 171 but the filter is not mounted, the detected member 90 comes into contact with the contact portion 515 of the rotating member 51. It is a position where it can be retracted backward from the contact portion 515 without doing so.

Specifically, as shown in FIGS. 8 and 9, the detected member 90 is a plate-shaped member that covers the opening 62 from the inside of the filter accommodating portion 65 at the first position. The detected member 90 is, for example, a plate-shaped member made of a hard synthetic resin or metal. A rectangular vent 91 (ventilation portion of the present invention) is formed in a substantially central portion of the member to be detected 90 to allow air flow from the inside of the filter accommodating portion 65 toward the outside of the opening 62.

Further, as shown in FIG. 8, the lower end portion 92 of the detected member 90 is supported on the back surface of the lower edge portion 621 of the opening 62. Specifically, on the back surface of the lower edge portion 621, an upward hook-shaped support rail 66 extending in the left-right direction D3 is provided, and the lower end portion 92 is supported by the support rail 66. Further, a portion other than the lower end portion 92 of the detected member 90 is not supported. Therefore, in the detected member 90, when the filter is not attached, the upper end portion 93 of the detected member 90 is in contact with the back surface of the upper edge portion 622 of the opening 62, and the detected member 90 is bent. The upper end portion 93 can be displaced from the back surface of the upper edge portion 622 to the second position separated from the back surface side to the inner side.

Further, the detected member 90 is provided with a detecting portion 95 (an example of the extending portion of the present invention) extending from the upper end portion 93 of the vent port 91 toward the center of the vent port 91. That is, the detection unit 95 extends downward from the upper end portion 93. The detection unit 95 is a portion detected by the filter detection mechanism 50. As shown in FIG. 8, the detection unit 95 extends from the back surface of the upper edge portion 622 of the opening 62 toward the center of the opening 62 in a state where the detected member 90 is arranged at the first position.

In the present embodiment, the detection unit 95 is provided at a position capable of contacting the contact portion 515 of the first detector 511 of the rotating member 51 in the process of mounting the collection box 16 on the box mounting portion 171. There is. Therefore, in the box-mounted state in which the collection box 16 is mounted on the box-mounted portion 171 and the detected member 90 is arranged at the first position, the detection unit 95 abuts on the rotating member 51. It is possible to come into contact with the portion 515. In this case, the second position where the detected member 90 can be displaced in the box-mounted state is a position separated from the contact portion 515 in a direction away from the rear with respect to the first position.

As described above, the cleaning robot 10 of the present embodiment includes a collection box 16, a dust collection filter 80, a filter detection mechanism 50, and a member to be detected 90. Therefore, when the collection box 16 is mounted on the box mounting portion 171 while the dust collecting filter 80 is mounted on the filter accommodating portion 65, the detecting portion 95 of the detected member 90 is mounted on the rotating member 51. It contacts the contact portion 515. As a result, the pressing force from the detection unit 95 to the contact portion 515 in the mounting direction to the box mounting portion 171 is applied to the rotating member 51 as the operating force for rotating the rotating member 51 in the rotating direction D11. To. In this case, the pressing force is larger than the elastic force of the elastic member 53. Therefore, the detection unit 95 rotates the rotating member 51 in the rotation direction D11 against the elastic force of the elastic member 53. As a result, the pressing portion 516 of the second detector 512 of the rotating member 51 presses the actuator 522, and the switch portion 52 operates. In this case, the control unit 40 can determine that the dust collection filter 80 is mounted while the collection box 16 is mounted.

If the detected member 90 is not provided, the contact portion 515 of the rotating member 51 directly contacts the dust collection filter 80 when the collection box 16 is mounted on the box mounting portion 171. In this case, since the dust collecting filter 80 is made of a soft material, the contact portion 515 is buried in the dust collecting filter 80, the rotating member 51 does not rotate in the rotation direction D11, and the switch portion 52 does not operate. There is a risk. On the other hand, in the present embodiment, since the contact portion 515 contacts the detection portion 95 of the detected member 90, the rotating member 51 can be reliably rotated in the rotation direction D11, and the switch portion 52 can be rotated. It can be operated reliably.

Further, when the collection box 16 is mounted on the box mounting portion 171 without the filter mounted on the dust collecting filter 80, even if the detected member 90 is arranged at the first position, the detection unit 95 does not apply the operating force to the contact portion 515. Specifically, when the detection unit 95 comes into contact with the contact portion 515 during the mounting process of the collection box 16, the elastic force of the elastic member 53 causes the contact portion 515 to move from the contact portion 515 to the detection unit 95 in the retracting direction toward the second position side. Pressing pressure is applied. As shown in FIG. 10, the detected member 90 moves from the first position to the second position by receiving this pressing force. In this case, since the rotating member 51 is held at the undetected position, the switch unit 52 does not operate. In this case, in the mounted state of the collection box 16, the control unit 40 can determine that the dust collecting filter 80 is not mounted.

As described above, in the present embodiment, when the dust collecting filter 80 is not mounted on the filter accommodating portion 65, the detected member 90 is freely displaceable between the first position and the second position. Therefore, even if the collection box 16 is mounted on the box mounting portion 171, the detected member 90 retracts to the second position. Therefore, it is possible to prevent the rotating member 51 from rotating in the rotation direction D11 and the switch portion 52 from malfunctioning.

In the above-described embodiment, the filter detection mechanism 50 is illustrated as an example of the sensor unit of the present invention, but the present invention is not limited to this configuration. For example, the switch unit 52 may integrally include the rotating member 51. In this case, the switch unit 52 is an example of the sensor unit of the present invention.

Further, in the above-described embodiment, the detected member 90 is exemplified as an example of the detected member of the present invention, but the present invention is not limited to this configuration. For example, as shown in FIG. 11, the detected member 90A may be applied instead of the detected member 90. The detected member 90A has a detection unit 95 capable of contacting the contact portion 515, and the detection unit 95 can contact the contact portion 515 of the rotating member 51 inside the filter accommodating portion 65. It is supported so as to be slidable between the first position and the second position separated from the contact portion 515 in the direction away from the contact portion 515. Specifically, a slide rail 97 is provided on the top surface of the filter accommodating portion 65, and the member to be detected 90A is slidably supported in the front-rear direction D2 by the slide rail 97.

Further, as shown in FIG. 12, the detected member 90B may be applied instead of the detected member 90. The upper end portion of the detected member 90B is rotatably supported by a support portion 98 provided inside the filter accommodating portion 65, and the detection portion 95 is provided at the lower end portion on the other side. .. The support portion 98 is provided on the back surface of the upper edge portion 622 of the opening 62. By rotatably supporting the upper end portion of the detected member 90B, the detected member 90B has a first position where the detection portion 95 can abut the contact portion 515 of the rotating member 51 and a contact portion. It is rotatable to and from a second position separated from 515 in a direction away from it.

Further, in the above-described embodiment, the configuration in which the collection box 16 is detachable from the box mounting portion 171 has been illustrated, but the configuration is not limited to this configuration of the present invention. For example, the present invention can be applied to a cleaning device or a dust collecting device in which the collecting box 16 is fixed to the box mounting portion 171 and the dust collecting filter 80 is detachably attached to the filter accommodating portion 65.
