In addition, the attached drawings and the following descriptions are provided to allow those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

(the overall structure of the vacuum cleaner) FIG. 1 is a schematic cross-sectional view of a stick cleaner 100 . FIG. 2 is a front view of the vacuum cleaner 100 . The vacuum cleaner 100 will be described with reference to FIGS. 1 and 2 .

The vacuum cleaner 100 has: a suction nozzle 130 for sucking dust on the floor; a vacuum cleaner body 110 mounted on the suction nozzle 130 so as to be tiltable in the front-rear direction relative to the suction nozzle 130; 112 extends upwards and is set. The vacuum cleaner body 110 and the grip part 140 shown in FIG. 1 and FIG. 2 are provided in an upright posture relative to the suction nozzle 130, and do not tilt forward from the upright posture. When the vacuum cleaner 100 is in use, the vacuum cleaner body 110 and the grip portion 140 are held by the user in a posture tilted backward relative to the suction nozzle 130 .

The suction nozzle 130 is equipped with the nozzle cover 132 wider than the cleaner main body 110, and forms the wide suction space 131 for sucking dust. The nozzle cover 132 is wide in the width direction, and can support the cleaner body 110 and the grip 140 in a state where the cleaner body 110 and the grip 140 are not easily tilted left and right in the upright posture. That is, as long as the upright cleaner body 110 and the handle 140 are not subjected to external force, the suction nozzle 130 can support the cleaner body 110 and the handle 140 while maintaining the upright posture of the cleaner body 110 and the handle 140 .

The inner space of the nozzle cover 132 functions as a suction space 131 for sucking dust on the floor surface. The suction space 131 opens toward the floor surface in the front portion of the nozzle cover 132 . In the rear side of the opening portion, the suction space 131 is closed by the bottom 134 of the nozzle cover 132 . A rotary scraper brush 133 is arranged in the suction space 131 , and the scraper brush 133 passes through the opening of the suction space 131 and is exposed from the nozzle cover 132 so as to be able to contact the floor surface.

The cleaner body 110 has a case 111 that is elongated in the vertical direction. The lower end of the housing 111 is attached to the rear of the nozzle cover 132 so as to allow the cleaner body 110 to tilt in the front-rear direction. The upper portion of the housing 111 becomes thinner toward the upper end 112 of the housing 111 , and a gripping portion 140 extends upward from the upper end 112 . The grip part 140 is a rod-shaped part having a thickness that can be gripped by a user. As shown in FIG. 2 , an operation unit 141 (operation button) operable by a user is provided on the grip unit 140 .

Inside the casing 111 are arranged various components for sucking up dust on the floor surface and storing the sucked up dust. As shown in FIG. 1 , a suction pipe 113 extending in the vertical direction is arranged inside the lower portion of the housing 111 , and a check valve 114 is attached to the upper end of the suction pipe 113 . A dust storage part 115 and a dust collection source 116 are provided above the check valve 114 , and the dust collection source 116 is provided above the dust storage part 115 . In addition, a battery 117 for supplying electric power to the dust suction source 116 is arranged above the dust suction source 116 . The suction source 116 is configured to generate upward suction force by receiving electric power from the battery 117 in response to the operation of the operation unit 141 . For example, the dust suction source 116 can also be composed of a fan and a motor.

The suction pipe 113 is fixed in the housing 111, and when the cleaner body 110 tilts backward from the upright posture (the posture shown in FIG. 1 ), it tilts backward together with the housing 111. When the cleaner body 110 is in an upright position, the lower end of the suction pipe 113 is in contact with the bottom 134 of the nozzle cover 132 . That is, when the cleaner body 110 is in an upright position, the lower end of the suction pipe 113 is closed by the bottom 134 of the nozzle cover 132 . When the cleaner body 110 tilts backward from the upright position, the lower end of the suction pipe 113 will move in the direction indicated by the arrow A in FIG. 1 . As a result, the inner space of the suction pipe 113 is in a state of communicating with the suction space 131 of the nozzle cover 132 .

A check valve 114 is installed on the upper end of the suction pipe 113, and the aforementioned check valve 114 blocks the upper end of the suction pipe 113 when the dust suction source 116 is not activated. Specifically, only the rear end of the check valve 114 is fixed to the suction tube 113 , and the rest of the check valve 114 is allowed to receive an upward external force to be in a state away from the upper end of the suction tube 113 . The check valve 114 can also be made of, for example, a thin rubber plate. In this case, when the dust suction source 116 is activated, the check valve 114 can be deformed upward due to the upward suction force of the dust suction source 116 , so as to open the opening of the upper end of the suction pipe 113 .

In order not to interfere with the upwardly bent check valve 114 , the dust storage portion 115 is fixed in the housing 111 at a position spaced upward from the check valve 114 . Dust storage unit 115 is provided to prevent dust from flowing into dust suction source 116 .

The dust storage part 115 has a shape of a container opening downward, and the inner space of the dust storage part 115 is used as a dust storage space for storing dust. Specifically, as shown in FIG. 3 , dust storage unit 115 has: mesh filter 118 forming the peripheral surface and upper surface of dust storage unit 115 ; and holding frame 119 configured to hold mesh filter 118 . The mesh filter 118 allows air to pass through and on the other hand captures dust contained in the air. As a result, the dust sucked up by the suction force of the dust suction source 116 is stored in the dust storage space surrounded by the mesh filter 118 .

In order to avoid interference with the check valve 114, the dust storage part 115 is arrange|positioned at the position separated upward from the check valve 114. As shown in FIG. Therefore, as shown in FIG. 1 and FIG. 4 , the space between the dust storage unit 115 and the check valve 114 functions as a communication path 120, and the aforementioned communication path 120 is used to release the dust stored in the dust storage unit 115. discharge. As shown in FIG. 4 , a discharge port 124 is formed on the front wall of the housing 111 to open into the communication path 120 . The discharge port 124 faces forward when the casing 111 is in an upright position. In order to open and close the discharge port 124 , a cover body 121 is attached to the casing 111 .

On the front wall of the casing 111 , a swivel shaft portion 123 rotatable around a substantially horizontal axis is provided below the discharge port 124 , and the cover 121 is configured to swivel up and down around the swivel shaft portion 123 . The lid body 121 shown in FIG. 1 assumes an upright posture, and is in a closed posture for closing the discharge port 124 . At this moment, the rotating shaft portion 123 is located at the lower end of the cover body 121 . On the other hand, the cover body 121 shown in FIG. 4 is swung downward by a predetermined angle (rotation angle of 90° or less) from the state of the closed posture. When the cover body 121 takes the posture shown in FIG. 4 , the cover body 121 becomes a state inclined upward from the rotation shaft portion 123 and is separated from the discharge port 124 . That is, the lid body 121 assumes an open posture in which the discharge port 124 is opened.

A potential energy imparting member 150 for imparting potential energy to the lid body 121 toward the closed posture may be provided on the rotation shaft portion 123 . For example, the potential energy imparting member 150 may also be formed by a torsion spring wound around the rotation shaft 123 to impart potential energy to the cover 121 in an upward rotation direction.

The cover body 121 is provided with a notch 125 recessed into a V-shaped cross section. On the other hand, a stop portion 126 protruding into the notch portion 125 is disposed on the front wall of the housing 111 . The stop portion 126 abuts against the cover body 121 when the cover body 121 rotates downward by a predetermined angle from the closed position.

In detail, the notch portion 125 has: a lower edge surface 127, which is close to the stop portion 126 when the cover body 121 is rotated downward; and an upper edge surface 128, which is away from the stop portion when the cover body 121 is rotated downward. 126. The lower edge surface 127 is configured to be in contact with the stopper portion 126 before the lid body 121 swung downward is in a horizontal posture. As a result, the cover body 121 is held by the housing 111 in the opened posture inclined upward from the pivot shaft portion 123, and does not swivel downward beyond the opened posture shown in FIG. 4 . In addition, the upper edge surface 128 is formed so as not to prevent the lid body 121 from taking the closed posture, and can be separated from the stopper portion 126 when the lid body 121 is in the closed posture.

(the overall structure of the recovery device) The dust stored in the dust storage unit 115 can be recovered by the recovery device 200 shown in FIG. 5 . The recovery apparatus 200 is provided with the housing|casing 210 and the base board 220, the housing 210 is attached to the front part, and the vacuum cleaner 100 is mounted in the rear part. A dust flow path 230 is provided in the casing 210 of the recovery device 200 , and one end of the dust flow path 230 is opened outside the casing 210 for the dust recovered from the vacuum cleaner 100 to flow in. The other end of the dust channel 230 is connected to the recovery chamber 240 , and a suction source 250 is disposed below the recovery chamber 240 . The suction source 250 is electrically connected to the control unit 260 in the casing 210 and operates under the control of the control unit 260 .

The casing 210 has: an upper part 212 for accommodating the dust flow path 230 , a recovery chamber 240 and a suction source 250 ; and a lower part 211 for accommodating the control part 260 . The upper portion 212 is a portion that contacts the cleaner body 110 when the cleaner 100 is mounted so that the dust flow path 230 communicates with the communication path 120 of the cleaner 100 . In order to avoid interference with the suction nozzle 130 protruding forward from the cleaner body 110, the lower part 211 of the housing 210 is formed smaller than the upper part 212 in the front-rear direction, and a hole for accommodating the suction nozzle 130 is formed behind the lower part 211. The accommodating space 213.

The upper part 212 of the housing 210 includes: a rear wall 214 formed to be connectable with the vacuum cleaner body 110 . Specifically, as shown in FIG. 6 , a groove portion 215 complementary to the front portion of the cleaner body 110 is provided on the rear wall 214 . As shown in FIG. 7 , the groove portion 215 is extended in the vertical direction. The front side portion of the cleaner body 110 in the upright posture is fitted into the groove portion 215 .

As shown in Figure 7, in the groove portion 215, a pair of small holes are formed on the upper part of the rear wall 214, and a pair of detection pieces 261 are arranged, and the aforementioned pair of detection pieces 261 are detected from the rear wall 214 through these small holes. The outer surfaces are each protruding. The detection pieces 261 are used to detect that the vacuum cleaner body 110 has been inserted into the groove portion 215 .

The detection piece 261 is endowed with potential energy in the direction protruding from the rear wall 214. When the cleaner body 110 is inserted into the groove 215, the cleaner body 110 will be pressed into the small hole to become immersed in the small hole. The signal generating part 262 is arranged in the casing 210, and the aforementioned signal generating part 262 is configured to detect whether the detection piece 261 is in the state of being submerged in the small hole, and generates an activation signal when detecting that the detection piece 261 is submerged in the small hole. . The signal generation unit 262 is electrically connected to the control unit 260 shown in FIG. 5 .

As shown in FIG. 5 , the dust flow path 230 is disposed in the upper portion 212 of the housing 210 and extends in the vertical direction. The upper end (the other end) of the dust passage 230 is connected to the recovery chamber 240 . As shown in FIG. 7 , a recovery port 216 opened in the rear wall 214 is formed in the concave groove portion 215 at the lower end (one end) of the dust flow path 230 .

The recovery port 216 is formed at the following position: when the vacuum cleaner 100 is placed on the pedestal plate 220 when the vacuum cleaner body 110 is in an upright posture, and the front part of the vacuum cleaner body 110 is fitted into the groove portion 215, it is the same as that shown in FIG. 4 . The positions where the discharge ports 124 overlap in the front-rear direction. That is, the recovery port 216 faces the discharge port 124 of the vacuum cleaner 100 when the vacuum cleaner 100 is installed in the recovery device 200 . The recovery port 216 has a size that allows the cover body 121 to enter the recovery port 216 when the cover body 121 of the vacuum cleaner 100 is in the open posture of FIG. 4 .

The recovery chamber 240 is provided to recover the dust that has flowed in from the dust storage unit 115 through the dust flow path 230 . The recovery chamber 240 is configured to allow the air inside the recovery chamber 240 to be sucked out by the suction source 250 on the lower side of the recovery chamber 240 . Recovery chamber 240 has a larger volume than dust storage unit 115 provided in vacuum cleaner 100 .

The suction source 250 is configured to suck the air in the recovery chamber 240 . When the vacuum cleaner 100 is installed in the recovery device 200 , the suction force of the suction source 250 acts on the cover 121 of the vacuum cleaner 100 through the recovery chamber 240 and the dust flow path 230 . The suction source 250 is configured to obtain an attractive force of a magnitude that overcomes the potential energy imparting force of the potential energy imparting member 150 of the cover 121, tilts the cover 121 from the closed position to the open position, and attracts the inside of the dust storage part 115. The attraction of dust. For example, the suction source 250 may also be composed of a fan and a motor.

(Explanation of the action of the vacuum cleaner at the time of cleaning work) The cleaner 100 is held by the user in a posture in which the cleaner body 110 and the grip 140 are inclined rearward with respect to the suction nozzle 130 during the cleaning operation. By making the cleaner main body 110 and the grip part 140 inclined backward with respect to the suction nozzle 130, it becomes easy to move the suction nozzle 130 forward while pushing. In this state, the inner space of the suction pipe 113 communicates with the suction space 131 of the suction nozzle 130 .

Afterwards, when the user operates the operation part 141 to activate the dust suction source 116 , the dust suction source 116 will generate an upward suction force. By this attractive force, the check valve 114 bends upward. As a result, the upper end of the suction tube 113 is opened.

When the upper end of the suction pipe 113 was opened, the suction force of the dust suction source 116 would act on the suction space 131 of the suction nozzle 130, and the dust on the floor surface would be sucked into the suction space 131. After that, the dust flows into the dust storage part 115 through the suction pipe 113 . The dust storage unit 115 captures dust and stores the captured dust.

When the user moves the suction nozzle 130 forward, the suction nozzle 130 may touch an obstacle, causing the vacuum cleaner 100 to be impacted. The cover 121 is given potential energy in the direction of closing the discharge port 124 by the potential energy imparting member 150 , so that the discharge port 124 is difficult to open even when the vacuum cleaner 100 receives an impact force. Even if the cover 121 is rotated due to the impact force and the discharge port 124 is temporarily opened, the discharge port 124 opens obliquely upward when the cleaner body 110 is tilted backward relative to the suction nozzle 130 . Therefore, the dust in the dust storage unit 115 is less likely to fall from the discharge port 124 .

When the cleaning operation is completed, the user operates the operation part 141 to stop the dust collection source 116 . As a result, since the suction force of the suction source 116 disappears, the check valve 114 returns to its original state and closes the upper end of the suction pipe 113 . Therefore, even if the dust in the dust storage unit 115 falls from the dust storage unit 115 , it remains in the communication path 120 .

(Explanation of the operation of the recovery device when collecting dust) The user attaches the vacuum cleaner 100 to the collection device 200 in order to collect the dust accumulated in the dust storage unit 115 of the vacuum cleaner 100 . Specifically, the user sets the vacuum cleaner 100 on the base plate 220 of the recovery device 200 , and sets the vacuum cleaner body 110 and the grip portion 140 in an upright posture. When the cleaner body 110 in the upright position fits into the groove 215 of the recovery device 200 , the cover 121 of the cleaner 100 faces the recovery port 216 of the recovery device 200 in the front-rear direction. Moreover, with the vacuum cleaner body 110 inserted into the groove portion 215 of the recovery device 200 , the detection piece 261 of the recovery device 200 will be pushed forward and submerged in the small hole of the rear wall 214 .

The fact that the detection piece 261 is immersed in the small hole is detected by the signal generation unit 262 . The signal generator 262 generates an activation signal in response to the detection that the detection piece 261 is submerged into the small hole. The activation signal is transmitted from the signal generating unit 262 to the control unit 260, and the control unit 260 operates the suction source 250 for a predetermined period in response to receiving the activation signal.

When the suction source 250 operates, the suction force of the suction source 250 acts on the cover 121 facing the recovery port 216 through the recovery chamber 240 and the dust flow path 230 . The lid body 121 receives the suction force of the suction source 250 , and as shown in FIG. 8 , tilts downward from a closed position for closing the discharge port 124 to an open position for opening the discharge port 124 . At this time, the upper end portion of the cover body 121 enters the lower end portion of the dust flow path 230 through the recovery port 216 .

When the cover 121 is rotated downward, the discharge port 124 will be opened. As a result, the dust storage space of the dust storage unit 115 is in a state of communicating with the recovery chamber 240 through the communication path 120 , the recovery port 216 , and the dust flow path 230 . Therefore, the dust stored in the dust storage part 115 flows into the recovery chamber 240 through the communication path 120 , the recovery port 216 and the dust flow path 230 sequentially by the suction force of the suction source 250 . As a result, the dust is recovered into the recovery chamber 240 .

It is conceivable that although the upper part of the cleaner body 110 is inserted into the groove 215 to press the detection piece 261, the lower part of the cleaner body 110 is away from the rear wall 214 of the recovery device 200, and in this state the The vacuum cleaner 100 is installed in the recovery device 200 . Like this, when the vacuum cleaner body 110 is installed obliquely with respect to the recovery device 200, as shown in FIG. A space is created between the rear walls 214 of 200 . In addition, it is conceivable that the discharge port 124 opens obliquely downward, and the dust falling from the dust storage part 115 to the communication path 120 is scattered from the discharge port 124 by the action of gravity.

The dust falling from the discharge port 124 by gravity can be received by the cover 121 . That is, the lid body 121 is held in an open posture in which it is swung downward from the discharge port 124 . Therefore, when the cover 121 is in the open position, the space between the front side portion of the housing 111 of the vacuum cleaner 100 and the rear wall 214 of the recovery device 200 faces the recovery device on the lower side of the discharge port 124 . 200 outstanding. Therefore, even if the dust falls from the outlet 124 , it can be received by the cover 121 .

At this time, the cover body 121 of the vacuum cleaner 100 enters the interior of the recovery device 200 through the recovery port 216 of the recovery device 200 . Therefore, the dust can be prevented from falling by the cover 121 , and move from the outlet 124 of the vacuum cleaner 100 to the recovery port 216 of the recovery device 200 to flow into the recovery device 200 .

The suction source 250 of the recovery device 200 stops after operating for a predetermined time. At this time, dust may remain on the cover 121 . Even if dust remains on the cover body 121 , since the cover body 121 assumes an upwardly inclined posture from the swivel shaft portion 123 , the dust will slide down toward the swivel shaft portion 123 side. Therefore, it is possible to prevent dust from falling from the front end side of the cover body 121 . While the dust is sliding toward the rotating shaft 123 , the cover 121 rotates upward around the rotating shaft 120 by the force of the potential energy imparting member 150 to close the discharge port 124 . Therefore, the dust remaining on the cover 121 can return to the communication path 120 between the dust storage part 115 and the check valve 114 through the outlet 124 .

In addition, in the above-mentioned embodiment, when the lid body 121 is in the open position, it protrudes from the housing 111 of the vacuum cleaner 100 in a state inclined upward obliquely. Alternatively, the lid body 121 may protrude from the casing 111 of the cleaner 100 in a substantially horizontal posture when it is in the opened posture.

In addition, in the above-described embodiment, the lid body 121 is turned up and down to take the closed posture or the open posture. Alternatively, the cover body 121 may be removable from the casing 111 of the vacuum cleaner 100, and may be attached to the casing 111 of the vacuum cleaner 100 in two postures of an open posture and a closed posture. In this case, when collecting dust toward the recovery device 200 , the user temporarily removes the cover 121 in the closed position from the housing 111 of the cleaner 100 , and then attaches the cover 121 to the case of the cleaner 100 in the open position. Body 111. In this state, as long as the user installs the vacuum cleaner 100 on the recovery device 200 and activates the recovery device 200 , the dust flowing from the vacuum cleaner 100 to the recovery device 200 can be prevented from falling and the dust can be recovered to the recovery device 200 . Afterwards, when the user uses the vacuum cleaner 100 , the cover 121 in the open position can be temporarily removed from the housing 111 of the vacuum cleaner 100 , and installed in the housing 111 of the vacuum cleaner 100 in the closed position. As a result, the user can use the vacuum cleaner 100 in a state where the discharge port 124 is closed by the cover body 121 .

Moreover, in the said embodiment, the cleaner main body 110 is attached to the suction nozzle 130 so that it can tilt backward from an upright posture by an operation of a user. As an alternative, the cleaner body 110 may not be able to tilt backward. In this case, the vacuum cleaner 100 can be used with the vacuum cleaner main body 110 maintaining the upright posture.

In the above-mentioned embodiment, although the cleaner body 110 does not tilt forward from the upright position, it is also possible to allow the cleaner body 110 to tilt forward as long as the cover body 121 in the open position can maintain the tilted upward position. tilt.

(effect, etc.) The vacuum cleaner 100 and the recovery device 200 of the above-mentioned embodiment have the following features and exert the following effects.

The vacuum cleaner according to one aspect of the above embodiment is configured to be connected to a recovery device having a recovery chamber for collecting dust. The vacuum cleaner has: a dust suction source, which generates an attractive force for attracting dust; a dust storage part, which has a dust storage space, and the dust storage space stores the dust attracted by the dust suction source; The dust storage space can be connected with the recovery room of the recovery device; and the cover can open and close the communication path. The cover opens the communication path in the posture of receiving dust, so as to prevent the dust from falling between the recovery device and the vacuum cleaner.

According to the above configuration, when the cover body opens the communication path in a state where the cleaner is connected to the recovery device, the dust storage space communicates with the recovery chamber of the recovery device. As a result, the dust in the dust storage space can be allowed to be discharged to the recovery device through the communication path. At this time, since the cover body opens the communication path in a posture of receiving dust, it is possible to suppress the dust from falling between the cleaner and the recovery device.

In the above configuration, the cover body may be configured to be able to swing downward from a closed posture for closing the communication passage to an open posture for opening the communication passage. The vacuum cleaner may also be further provided with a stopper, and the aforementioned stopper, when the cover is rotated from the closed position to the open position, at the position where the cover is rotated by a predetermined angle and has become an obliquely upward position, the cover will stop.

According to the above configuration, when the cover body is rotated downward by a predetermined angle from the closed posture of closing the communication passage, the rotation of the cover body is stopped by the stopper. At this time, since the cover body is inclined upward, even if the dust remains on the cover body after collecting the dust toward the recovery device, the dust will return to the cleaner side, making it difficult to spill from the front end of the cover body. .

In the above configuration, the cover body may be configured to be able to rotate between a closed posture for closing the communication passage and an open posture for opening the communication passage. The cleaner may further include a potential energy imparting member that imparts potential energy to the lid toward the closed posture.

According to the above configuration, since the potential energy is applied to the closed position by the potential energy imparting member, the cover body becomes less likely to take the open position unnecessarily. Therefore, for example, it is possible to prevent the communication path from being opened when the vacuum cleaner is not attached to the recovery device.

In the above configuration, the vacuum cleaner may further include: a casing forming a communication path and accommodating a dust collection source and a dust storage portion; and a suction nozzle for sucking dust by the suction force of the dust collection source. The housing may be attached to the suction nozzle in such a manner that it can be tilted backward from the upright position by the operation of the user. The cover body may also be provided to open and close the communication path opened on the front wall of the casing.

According to the above configuration, the user can tilt the housing backward relative to the suction nozzle, and perform cleaning work while pushing out the suction nozzle. At this time, by tilting the case backward, the communication path opened on the front wall of the case opens obliquely upward, and the lid that has closed the opening of the communication path acts on the body that maintains the closed position due to gravity. direction. Therefore, the lid body becomes difficult to open during cleaning work.

The collection device of one aspect of the above-mentioned embodiment is configured so that the above-mentioned vacuum cleaner can be attached. The recovery device has: a recovery room for recovering dust; a dust flow path, one end of which is connected to the recovery room, and communicates with the communication path when the vacuum cleaner is installed in the recovery device; In this state, the suction force acts on the cover to make the cover open to open the communication path, and in the state where the cover is in the open position, the dust is sucked into the recovery chamber through the communication channel and the dust flow channel. The cover body is formed so as to enter the dust flow path when it is in the open position.

According to the above configuration, when the suction source applies a suction force to the cover to open the cover with the cleaner attached to the recovery device, the dust flow path of the recovery device communicates with the communication path. In this state, the suction force of the suction source can act on the dust in the dust storage part through the dust flow path and the communication path. Therefore, the dust in the dust storage space flows into the recovery chamber of the recovery device through the communication path and the dust flow path. At this time, since the cover is in the state of entering the dust flow path, the dust is prevented from falling by the cover and moves toward the other end of the dust flow path.

Industrial availability The vacuum cleaner and recovery device of the above-mentioned embodiments are suitably utilized as devices used in cleaning work.
