Description

Dust collection device

The invention relates to a dust collecting device for attracting dust and storing the attracted dust.

A suction-type dust collector (for example, a vacuum cleaner or a recovery device that collects dust from a vacuum cleaner) has a suction source that generates a suction force that attracts dust and generates a suction airflow that transports the dust. The dust collector is configured to store the dust transported by the suction airflow in the dust storage unit (see Japanese Patent Laid-Open No. 2012-75446).

The dust collector of JP-A-2012-75446 further includes an ion generating unit in order to remove static electricity generated in the dust storage unit. The ion generating part is configured to release ions in the suction airflow, and let the ions flow to the dust storage part along the suction air flow, thereby performing static elimination treatment against static electricity generated in the dust storage part.

Ions not only have a static elimination effect, but also have a deodorizing effect. However, in order to obtain a deodorizing effect on the dust in the dust storage to a degree recognizable by the user, it is necessary to supply ions to the dust storage for a longer time (for example, about 3 hours) than the cleaning time. That is, in the vacuum cleaner disclosed in Japanese Patent Application Laid-Open No. 2012-75446, in order to deodorize the dust in the dust storage, it is necessary to activate the suction source over a long period of time in order to supply ions to the dust storage.

However, the suction source is configured to generate a suction force for attracting dust, and consumes a large amount of power. Therefore, if the suction source is activated over a long period of time for deodorizing the dust in the dust storage unit, the power consumption of the vacuum cleaner becomes excessive.

An object of the present invention is to provide a dust collector capable of deodorizing dust while suppressing power consumption.

The dust collecting device in this disclosure has: a suction source that generates a suction force that attracts dust, thereby generating a suction airflow that transports the dust; a dust storage unit that stores dust transported by the suction airflow; and an ion generation unit that generates ions; And the ion supply unit generates a supply airflow for supplying ions generated from the ion generation unit to the dust storage unit with power consumption smaller than that of the suction source.

The above-mentioned dust collector can deodorize dust while suppressing power consumption.

The purpose, characteristics and advantages of the present invention will become more apparent with the following detailed description and attached drawings.

form for carrying out the invention Hereinafter, the embodiments will be described in detail while referring to the drawings. However, in order to facilitate understanding by those skilled in the art, for example, detailed descriptions of well-known items may be omitted, or substantially the same items may be omitted.

As shown in FIG. 1 , the dust collector can be configured as a collection device 200 for collecting dust from a vacuum cleaner 100 .

(the overall structure of the vacuum cleaner) As shown in Figures 1 and 2, the vacuum cleaner 100 has: a suction nozzle 130 for inhaling dust; a vacuum cleaner body 110 installed at the rear of the suction nozzle 130; The grip portion 140 is a portion that can be gripped by a user when the vacuum cleaner 100 is used. As shown in FIG. 1 , when the vacuum cleaner 100 is mounted on the recovery device 200, the vacuum cleaner body 110 and the grip portion 140 are set to stand upright with respect to the suction nozzle 130, but when the vacuum cleaner 100 is used, it can be set from an upright position. A posture in which the posture is tilted backward.

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 suction space 131 of the nozzle cover 132 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.

Inside the housing 111, various components are built in for sucking up dust on the floor surface and storing the sucked up dust. Specifically, as shown in FIG. 1 , a suction pipe 113 extending in the vertical direction is arranged inside the lower portion of the casing 111 . In addition, a dust storage chamber 152 is provided above the suction pipe 113, and a dust storage filter 115 is arranged in the dust storage chamber 152. The dust storage filter 115 captures dust while allowing air to pass through. On the upper side of the dust storage filter 115, the suction fan 116 is arrange|positioned, The said suction fan 116 generate|occur|produces the upward suction force which sucks up the dust on the floor surface. A battery 117 for supplying electric power to the suction fan 116 is arranged above the suction fan 116 .

As shown in FIG. 3 , the dust storage chamber 152 is provided with a dust outlet 124 opened on the front surface of the casing 111 . The dust outlet 124 is opened (the state shown in FIG. 3 ) or closed (the state shown in FIGS. 1 and 2 ) by the cover body 121 . The cover body 121 is configured to be rotatable up and down, and closes the dust outlet 124 in the upright posture (closed posture) shown in FIGS. 1 and 2 . On the other hand, the cover body 121 shown in FIG. 3 is rotated downward by a predetermined angle (rotating angle of 90° or less) from the closed position. When the cover body 121 takes the posture shown in FIG. 3, the opening portion of the dust storage chamber 152 is opened. That is, the lid body 121 is in the open posture which opens the dust discharge port 124. As shown in FIG. In addition, the lid body 121 is provided with a potential energy imparting member 150 that imparts potential energy to the lid body 121 toward the closed posture, thereby preventing the lid body 121 from taking the open posture unnecessarily. For example, the potential energy imparting member 150 may also be formed by a torsion spring wound around the rotation shaft of the cover 121 to impart potential energy to the upward rotation direction of the cover 121 .

The dust storage filter 115 in the dust storage chamber 152 has a shape of a container opened downward. Specifically, as shown in FIG. 4 , the dust filter 115 has a mesh filter 118 forming the peripheral surface and the upper surface of the dust filter 115 , and a holding frame 119 configured to hold the 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 of the suction fan 116 is stored in the space surrounded by the mesh filter 118 .

As shown in FIG. 1 , the suction pipe 113 extends vertically below the dust storage chamber 152 to form a flow path for dust to flow when the vacuum cleaner 100 is in use. 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 suction fan 116 is not activated. Specifically, only the rear end of the check valve 114 is fixed to the suction pipe 113 , and the rest of the check valve 114 is allowed to be away from the upper end of the suction pipe 113 by the upward suction force of the suction fan 116 . The check valve 114 can also be made of, for example, a thin rubber plate. In this case, when the suction fan 116 operates, the check valve 114 can be deformed upward due to the upward suction force of the suction fan 116 , thereby opening the upper end of the suction pipe 113 .

The suction fan 116 is fixed to the upper side of the dust storage chamber 152 . The suction fan 116 includes: a motor; and a blade portion formed to generate an upward airflow by being rotated by the motor.

That is, the recovery port 216 faces the dust discharge port 124 of the vacuum cleaner 100 when the vacuum cleaner 100 is installed in the recovery device 200 . Recovery port 216 has a size that allows cover 121 to enter recovery port 216 when cover 121 of vacuum cleaner 100 is in the open position of FIG. 3 .

A pair of small holes are formed on the upper side of the recovery port 216 , and a pair of detection pieces 261 are provided. The pair of detection pieces 261 respectively protrude from the outer surface of the rear wall 214 through the small holes. 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 part 262 is electrically connected to the control part 260 shown in FIG. 1 .

As shown in FIG. 1 , the dust flow path 230 is disposed in the upper portion 212 of the casing 210 . The dust flow path 230 includes a lower flow path 231 having the above-mentioned recovery port 216 , and an upper flow path 232 disposed at a higher position than the lower flow path 231 and connected to the dust storage unit 240 . An intermediate flow path 233 extending vertically is provided between the upper flow path 232 and the lower flow path 231 , and the upper flow path 232 and the lower flow path 231 are connected by the middle flow path 233 .

Dust storage unit 240 has a larger volume than dust storage chamber 152 of vacuum cleaner 100 . As shown in FIG. 5 , the dust storage part 240 is configured to form a rectangular space in a plan view, and includes a rear wall 241 , a front wall 242 , a right wall 243 , a left wall 244 and a bottom wall 245 . An opening is provided in the rear wall 241 , and the opening is connected to the upper flow path 232 of the dust flow path 230 . A circular opening is formed in the bottom wall 245, and the dust filter 247 is attached to this opening. The dust filter 247 is configured to capture dust while allowing air to pass through.

A suction source 250 is disposed below the dust filter 247 , and the suction source 250 is configured to suck the air in the dust storage unit 240 through the dust filter 247 . 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 dust storage part 240 and the dust flow path 230 . The suction source 250 is configured to obtain a suction force of a magnitude that overcomes the potential energy imparting force of the potential energy imparting member 150, tilts the lid body 121 from the closed position to the open position, and attracts dust in the dust storage chamber 152. force. For example, the suction source 250 may also be composed of a fan and a motor that rotates and drives the fan.

(Deodorization treatment section of the recovery unit) The deodorization processing part 270 for deodorizing the dust in the dust storage part 240 is provided near the lower flow path 231 of the dust flow path 230 . As shown in FIG. 7 , the deodorization processing unit 270 has an ion flow path 272 through which ions for deodorizing dust flow. The ion flow path 272 includes: an upstream end portion 273, which is arranged on the lower side of the lower flow path 231 of the dust flow path 230; a downstream end portion 275, which is connected to the ion flow inlet 271 of the dust flow path 230; and an intermediate portion 277, which is connected to the upstream end 273 and downstream end 275 .

The upstream end portion 273 is formed with a flow path extending in the left-right direction, and an ion supply unit 274 is disposed on the upstream end portion 273. The ion supply unit 274 generates a supply airflow for supplying ions to the dust storage unit. 240. Since ions are lighter than dust, ion supply unit 274 is configured to operate with lower power consumption than suction source 250 for attracting dust. For example, the ion supply unit 274 may be composed of a fan and a motor, and the motor rotates and drives the fan with lower power consumption than the motor of the suction source 250 .

The middle portion 277 extends upward from the upstream end portion 273 on the left side of the lower flow path 231 of the dust flow path 230 , and the upper end of the middle portion 277 is connected to the downstream end portion 275 .

The downstream end portion 275 has a flow path extending obliquely upward from the upper end of the intermediate portion 277 toward the ion inflow port 271 . A valve 276 for opening and closing the ion flow path 272 is accommodated at the downstream end portion 275 of the ion flow path 272 . In this embodiment, a ball valve is used as the valve 276 . In addition, the valve 276 shown in FIG. 7 is located at the position which closes the upper end of the intermediate part 277, and the position of the valve 276 shown in FIG. 7 is called a "closed position" in the following description. In addition, the valve 276 is formed so lightly that it can be floated by the supply airflow generated by the ion supply unit 274 .

As shown in FIG. 8 , an ion release cylinder 280 is provided at the upstream end 273 of the ion flow path 272 , and the ion release cylinder 280 protrudes from the side wall of the upstream end portion 273 to the inside of the ion flow path 272 .

A voltage application unit 285 is connected to the discharge electrode 283 , and a voltage is applied to the discharge electrode 283 by the voltage application unit 285 . The opposite electrode 284 is fixed in the ion generating box 281 in a grounded state, and when the voltage applying part 285 applies a voltage to the discharge electrode 283, a potential difference will be generated between the discharge electrode 283 and the opposite electrode 284, thereby creating an electric potential difference between them. Discharge occurs in between. Ions are generated by this discharge.

The voltage applying part 285 , the ion supply part 274 and the suction source 250 of the ion generating part 282 are electrically connected to the control part 260 and controlled by the control part 260 .

(Explanation of action) During cleaning operation, when the suction fan 116 of the vacuum cleaner 100 is activated, the check valve 114 is opened by the suction force generated by the suction fan 116, and the dust on the ground will be sucked up to the ground through the suction nozzle 130 and the suction pipe 113. Dust storage room 152. Dust flowing into the dust storage chamber 152 is captured by the dust storage filter 115 . When the cleaning operation is finished, the suction fan 116 of the vacuum cleaner 100 is stopped, and the check valve 114 closes the upper end of the suction pipe 113 . Therefore, the dust captured by the dust storage filter 115 does not fall to the suction pipe 113 but stays in the dust storage chamber 152 .

In order to recover the dust accumulated in the dust storage chamber 152 of the vacuum cleaner 100 , the vacuum cleaner 100 is attached to a recovery device 200 . Specifically, the cleaner 100 is installed on the base plate 220 of the recovery device 200 in a state where the cleaner body 110 and the grip portion 140 are 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. In this state, the detection piece 261 of the recovery device 200 is pushed forward by the vacuum cleaner body 110 , and the detection piece 261 is 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 generation unit 262 to the control unit 260, and the control unit 260 activates the suction source 250 for a predetermined time 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 dust storage portion 240 and the dust flow path 230 . The cover body 121 receives the suction force of the suction source 250, and as shown in FIG. 3 , tilts downward from the closed posture of closing the dust discharge port 124, and becomes the opening posture of opening the dust discharge port 124, so that the dust discharge port 124 becomes an open state. . As a result, dust storage chamber 152 of vacuum cleaner 100 communicates with the internal space of dust storage unit 240 through dust flow path 230 . In this state, the dust in the dust storage chamber 152 of the vacuum cleaner 100 is generated to flow into the dust flow path 230, and the dust in the dust storage chamber 152 will flow in the dust flow path 230 along the suction air flow, and flow into the recovery device. In the dust storage part 240 of 200. In the dust storage unit 240 , dust is captured by the dust removal filter 247 and stored in the dust storage unit 240 .

In addition, the valve 276 is kept in the closed position by the action of gravity during the operation of the suction source 250 , and the valve 276 is arranged at the downstream end 275 of the ion flow path 272 connected to the dust flow path 230 . Therefore, the suction air flow does not flow to the ion flow path 272 but flows toward the dust storage unit 240 .

When the operation time of the suction source 250 ends, the control unit 260 stops the suction source 250 . As a result of the stop of the suction source 250 , the suction force acting on the cover 121 of the vacuum cleaner 100 disappears, and the cover 121 returns to the closed position by the potential energy imparting member 150 . When the cover 121 returns to the closed position, the dust outlet 124 of the vacuum cleaner 100 is closed. At this time, as shown in FIG. 1 , the recovery port 216 of the recovery device 200 is also in a closed state by the lid body 121 .

The dust storage part 240 has a larger volume than the dust storage chamber 152 of the vacuum cleaner 100, and can store a large amount of dust. When a large amount of dust is accumulated in the dust storage unit 240 , the odor generated from the dust may become a problem. In order to suppress the odor generated from dust, the control unit 260 operates the ion generating unit 282 and the ion supply unit 274 after the suction source 250 stops. The control unit 260 operates the ion generating unit 282 and the ion supply unit 274 for a period of time (for example, about 3 hours) that is considered to provide a sufficient deodorizing effect on the dust in the dust storage unit 240 . The operation time of the ion generating part 282 and the ion supply part 274 is longer than the length of time required to collect dust from the vacuum cleaner 100 by the suction source 250 (that is, the operation time of the suction source 250 ).

When the ion generating part 282 operates, the voltage applying part 285 applies a voltage to the discharge electrode 283 . As a result, a potential difference is generated between discharge electrode 283 and counter electrode 284 . This potential difference generates a discharge between the discharge electrode 283 and the counter electrode 284 . Ions are generated by this discharge. The ions are released into the ion channel 272 through the ion release cylinder 280 by the force of the discharge between the discharge electrode 283 and the counter electrode 284 .

At this time, the ion supply unit 274 generates a supply airflow. As shown in FIG. 9 , the supply air flow floats the valve 276 . That is, the valve 276 moves to the open position that opens the ion flow path 272 . As a result, the upper end of the middle portion 277 of the ion flow path 272 is opened, so that the flow path for supplying the ions released into the ion flow path 272 to the dust flow path 230 is opened. The ions flow into the dust flow path 230 through the ion flow port 271 together with the supply air flow (see arrow in FIG. 9 ) flowing in the ion flow path 272 . At this time, since the recovery port 216 of the dust flow path 230 is closed by the cover 121 of the cleaner 100 , the supply airflow flowing into the dust flow path 230 flows toward the dust storage unit 240 . The ions reach the dust storage unit 240 by the supply airflow flowing toward the dust storage unit 240 to deodorize the dust in the dust storage unit 240 .

In the above embodiment, the ions are transported to the dust storage part 240 not by the suction air flow but by the supply air flow generated by the suction source 250 for recovering the dust from the vacuum cleaner 100. The airflow is an airflow generated by the ion supply unit 274 provided separately from the suction source 250 . Since the ion supply unit 274 generates the supply airflow with lower power consumption than the suction source 250 , even if the ion supply unit 274 is operated for a long time, the amount of power consumption does not become excessive.

Since the supply airflow is generated with a small power consumption, it may become weaker than the suction airflow generated with a large power consumption. However, since the ions transported by the supply air flow are lighter than the dust transported by the suction air flow, they can be transported to the dust storage unit 240 even by a weak supply air flow.

Since the ions transported by the supply air flow are used to deodorize the dust transported to the dust storage unit 240 by the suction air flow, the generation time of the supply air flow is set after the generation time of the suction air flow. That is, the operating time of the ion supply unit 274 is set after the operating time of the suction source 250 , and these operating times do not overlap in time. Since the ion supply unit 274 and the suction source 250 do not operate at the same time, peaks in the power consumption of the recovery device 200 can be suppressed.

By staggering the operation time of the ion supply unit 274 and the suction source 250, the supply air flow for ion transport and the suction air flow for dust transport do not obstruct the flow of each other. Therefore, it is permissible to employ a piping structure in which the ion flow path 272 is connected to the dust flow path 230 . By adopting such a piping structure, a part of the dust flow path 230 (that is, the flow path section from the ion inflow port 271 to the dust storage part 240 of the dust flow path 230 ) can be used for both ion transport and dust transport. In this case, the recovery device 200 can be downsized compared with a recovery device having a structure in which the ion flow path 272 is extended from the ion supply part 274 to the dust storage part 240 .

In the above embodiment, the valve 276 is arranged at the downstream end 275 of the ion flow path 272 in order to prevent the suction air from the dust flow path 230 from flowing into the ion flow path 271 through the ion inflow port 271 . The valve 276 is held at a closed position that blocks the upper end of the middle portion 277 of the ion flow path 272 by the action of gravity while the suction air flow flows in the dust flow path 230 . Therefore, the suction airflow does not flow into the ion flow path 272 . On the other hand, when the supply air flow for ion transport is generated by the ion supply unit 274 , the valve 276 is floated by the supply air flow, and the upper end of the intermediate portion 277 of the ion flow path 272 is opened. As a result, the ions sequentially pass through the ion flow path 272 and the dust flow path 230 to reach the dust storage unit 240 . In this way, the opening and closing operation of the valve 276 does not require electrical control.

In the above embodiment, a ball valve is used as the valve 276 . Alternatively, the valve 276 may be formed using a thin plate-shaped valve component. Alternatively, a solenoid valve may also be used as the valve 276, but electrical control becomes necessary.

In the above embodiment, the valve 276 is arranged at the downstream end portion 275 of the ion flow path 272 . Alternatively, the valve 276 may also be disposed at the middle portion 277 or the upstream end portion 273 of the ion flow path 272 .

In the above embodiment, the ion flow path 272 is connected to the dust flow path 230 . Alternatively, the ion channel 272 may also be connected to the dust storage part 240 .

In the above embodiment, the control unit 260 operates the ion supply unit 274 and the ion generation unit 282 after the suction source 250 stops. Not limited thereto, the control unit 260 may operate the ion supply unit 274 and the ion generation unit 282 periodically.

In the above-described embodiment, the dust collector is configured as the collection device 200 for collecting dust from the vacuum cleaner 100 . Alternatively, the dust collector may also be configured as the vacuum cleaner 100 . In this case, as shown in FIG. 10 , the deodorizing unit 270 may be formed around the suction pipe 113 of the vacuum cleaner 100 .

For example, the ion inflow port 271 can also be disposed on the suction tube 113 . The ion flow channel 272 can also be connected to the suction tube 113 in the ion inflow port 271 and extended downward. An ion supply unit 274 is provided at the lower end of the ion flow path 272 to generate an upward supply air flow, and a valve 276 may be provided at a downstream end portion 275 of the ion flow path 272 . In addition, the ion generation part 282 may be provided on the upper side of the ion supply part 274 to release ions into the ion flow path 272 . The ion supply unit 274 and the voltage application unit 285 of the ion generation unit 282 can be connected to the control unit 263 .

The control unit 263 can also be connected to the posture sensor 264, and the posture sensor 264 can detect whether the vacuum cleaner body 110 of the vacuum cleaner 100 has become an upright posture or has become a tilted posture tilted from the upright posture. In this case, the control unit 263 is configured to operate the ion supply unit 274 and the voltage application unit 285 for a predetermined period of time when the posture sensor 264 detects that the cleaner body 110 is in an upright posture.

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 of the suction nozzle 130 . In this state, when the ion supply part 274 generates a supply airflow, the supply airflow flows into the suction pipe 113 through the ion inflow port 271 and flows upward. The supply air flow flowing upward in the suction pipe 113 opens the check valve 114 of the suction pipe 113 upward, and flows into the dust storage chamber 152 (dust storage unit). During this period, as long as the ion generation part 282 releases ions to the ion flow path 272, the ions will flow into the dust storage chamber 152 (dust storage part) along the supply air flow, and the dust in the dust storage chamber 152 (dust storage part) will Deodorize.

The deodorization processing part 270 shown in FIG. 10 is provided in the stick type (stick type) cleaner 100. As shown in FIG. Alternatively, the deodorizing processing unit 270 may be incorporated in a canister type cleaner.

(effect, etc.) The dust collector of the above-mentioned embodiment has the following characteristics and exhibits the following effects.

The dust collecting device in one aspect of the above-mentioned embodiment includes: a suction source that generates a suction force for attracting dust, thereby generating a suction air flow that transports the dust; a dust storage unit that stores dust transported by the suction air flow; and an ion generation unit that uses The ion generation; and the ion supply unit generates a supply airflow for supplying ions generated from the ion generation unit to the dust storage unit with power consumption smaller than that of the suction source.

According to the above configuration, the supply air flow generated by the ion supply unit in order to send ions into the dust storage unit only needs to be able to send ions into the dust storage unit, and does not need to be as strong as the suction air flow generated by the suction source to transport dust. degree. Therefore, the ion supply unit may be configured to generate the supply airflow with power consumption smaller than that of the suction source. Therefore, even if the ion supply is operated for a long time in order to obtain a deodorizing effect on dust, the power consumption of the dust collector does not become excessive.

In the above configuration, the dust collector may further include a control unit that controls the suction source, the ion supply unit, and the ion generation unit. The control unit may be configured to operate the ion supply unit and the ion generation unit after stopping the suction source.

According to the above configuration, since the control unit activates the ion supply unit and the ion generation unit after stopping the suction source, the ion supply unit and the ion generation unit do not operate simultaneously with the suction source. Therefore, the peak value of the power consumption of the dust collector can be suppressed.

In the above configuration, the dust collecting device may also include: a dust flow path connected to the dust storage part for the suction air flow to flow toward the dust storage part; and an ion flow path extended from the ion supply part for the supply air flow to flow. The ion flow path can also be connected to the dust flow path, so that the supply air flows from the ion flow path through a part of the dust flow path into the dust storage part.

According to the above configuration, since the ion flow path is connected to the dust flow path for the supply air flow to flow into the dust storage part from the ion flow path through a part of the dust flow path, the dust flow path can be utilized as a device for supplying ions to the dust storage part. part of the flow path. Therefore, compared with the structure in which the ion flow path is connected to the dust storage part differently from the dust flow path, the dust collector can be downsized.

In the above configuration, the dust collecting device may further include: a dust flow path connected to the dust storage part for the suction air flow to flow toward the dust storage part; an ion flow path extended from the aforementioned ion supply part for the supply air flow to flow ; and a valve to open and close the ion flow path. The ion flow path can also be connected to the dust flow path, so that the supply air flows from the ion flow path through a part of the dust flow path into the dust storage part. The valve may also be configured to be held at the closed position for closing the ion flow path when the ion supply unit is not in operation, and to be displaced to the open position for opening the ion flow path when the ion supply unit is in operation.

According to the above configuration, the suction source is activated before the ion supply unit is activated, and the suction air flow is made to flow in the dust flow path. The ion flow path is connected to the dust flow path, but at this time, the ion flow path is closed by a valve. Therefore, the suction airflow does not flow into the ion flow path, but can flow into the dust storage part. Afterwards, as long as the ion supply part operates, the valve at the closed position will be displaced to the open position by the supply airflow, and the supply airflow can pass through the ion flow path to reach the dust storage part.

In the above configuration, the dust collector may further include a control unit that controls the suction source, the ion supply unit, and the ion generation unit. The control unit may be configured to operate the ion supply unit and the ion generation unit for a time longer than the time set for the operation of the suction source.

According to the above configuration, since the control unit operates the ion supply unit and the ion generation unit over a period longer than the time for operating the suction source, ions can be supplied to the dust storage unit over a relatively long period of time. As long as the ions are supplied to the dust storage part over a long period of time, the dust in the dust storage part can be deodorized by the ions.

Industrial availability The dust collecting device of the above-mentioned embodiment is suitably utilized as a device used for cleaning work.
