Abstract
The dust collecting device of the present application includes: a suction source that generates a suction force for sucking dust and a suction airflow for conveying the dust; a dust storage unit for storing dust conveyed by the suction airflow; an ion generating unit that generates ions; and an ion supply section that generates a supply air flow that supplies ions generated by the ion generation section to the dust storage section with power consumption smaller than that of the suction source.
Description
Technical Field
The present invention relates to a dust collecting device that sucks dust and stores the sucked dust.
Background
A suction type dust collecting device (e.g., a dust collector or a recovery device that recovers dust from the dust collector) has a suction source that generates a suction force for sucking the dust and generates a suction air flow for transporting the dust. The dust collecting device is configured to store dust carried by the suction air flow in a dust storage portion (see patent document 1).
The dust collecting device of patent document 1 further includes an ion generating unit for removing static electricity generated in the dust storage unit. The ion generating unit is configured to release ions into the suction airflow, and to discharge static electricity generated in the dust storage unit by allowing the ions to flow to the dust storage unit by the suction airflow.
The ions have not only a deodorizing effect but also a deodorizing effect. However, in order to obtain a deodorizing effect of dust in the dust storage section to a degree that allows a user to recognize, it is necessary to supply ions to the dust storage section for a longer period of time (for example, about 3 hours) than the cleaning time. That is, in the cleaner of patent document 1, if the deodorizing treatment of the dust in the dust storage part is to be performed, the suction source must be operated for a long period of time in order to supply the ions to the dust storage part.
However, the suction source consumes a large amount of power because it is configured to generate a suction force for sucking dust. Therefore, if the suction source is operated for a long period of time in order to deodorize the dust in the dust storage portion, the power consumption of the cleaner becomes excessive.

Detailed Description
The embodiments will be described in detail below with reference to the drawings, but for the sake of easy understanding by those skilled in the art, for example, detailed descriptions of already known matters or repeated descriptions of substantially the same configuration may be omitted. Furthermore, the figures and the following description are provided to enable those skilled in the art to fully understand the present invention, and are not intended to limit the subject matter recited in the scope of the present invention.
As shown in fig. 1, the dust collecting device may be configured as a recovery device 200 that recovers dust from the dust collector 100.
(integral Structure of vacuum cleaner)
As shown in fig. 1 and 2, the vacuum cleaner 100 includes: a suction nozzle 130 for sucking dust; a cleaner body 110 mounted at the rear of the suction nozzle 130; a grip 140 extending upward from the upper end 112 of the cleaner body 110. The grip 140 is a portion to be gripped by a user when the cleaner 100 is in use. As shown in fig. 1, in a state where the cleaner 100 is mounted on the collecting device 200, the cleaner body 110 and the grip 140 are in an upright posture standing upright with respect to the suction nozzle 130, and can be changed from the upright posture to a posture tilted rearward when the cleaner 100 is in use.
The suction nozzle 130 includes a nozzle housing 132 having a width wider than that of the cleaner body 110 so as to form a wide suction space 131 for sucking dust. The nozzle housing 132 is wide in the width direction, and can support the cleaner body 110 and the grip 140 in a state in which the cleaner body 110 and the grip 140 in the upright posture are difficult to tilt in the left-right direction. That is, as long as the upright cleaner body 110 and the grip 140 are not subjected to external force, the suction nozzle 130 can support the cleaner body 110 and the grip 140 in a state in which the upright posture of the cleaner body 110 and the grip 140 is maintained.
The suction space 131 of the suction nozzle housing 132 is opened toward the floor at a front side portion of the suction nozzle housing 132. On the rear side of the opening portion, the suction space 131 is closed based on the bottom 134 of the suction nozzle housing 132. A rotary cleaning brush 133 is disposed in the suction space 131, and the cleaning brush 133 is exposed from the nozzle housing 132 through an opening of the suction space 131 so as to be contactable with the floor.
The cleaner body 110 has a frame 111 elongated in the up-down direction. The lower end of the frame 111 is attached to the rear of the nozzle housing 132 so as to allow the cleaner body 110 to tilt in the front-rear direction.
In the housing 111, various members for sucking up dust on the floor and storing the sucked dust are incorporated. Specifically, as shown in fig. 1, a suction pipe 113 extending in the vertical direction is disposed in the lower portion of the housing 111. Further, a dust storage chamber 152 is provided above the suction pipe 113, and a dust storage filter 115 that captures dust and allows air to pass through is provided in the dust storage chamber 152. A suction fan 116 for generating upward suction force for sucking up dust on the floor is disposed above the dust storage filter 115. A battery 117 that supplies power to the suction fan 116 is disposed on the upper side of the suction fan 116.
As shown in fig. 3, the dust storage chamber 152 is provided with a dust discharge port 124 that opens to the front side surface of the housing 111. The dust discharge port 124 is opened (state shown in fig. 3) or closed (state shown in fig. 1 and 2) based on the cover 121. The cover 121 is configured to be swingable up and down, and to close the dust discharge port 124 in an upright posture (closed posture) as shown in fig. 1 and 2. On the other hand, the lid 121 shown in fig. 3 swings downward from the closed position by a predetermined angle (swing angle of 90 ° or less). When the cover 121 is in the posture shown in fig. 3, the opening portion of the dust storage chamber 152 is opened. That is, the cover 121 is in an open position to open the dust discharge port 124. The lid 121 is provided with a biasing member 150 for biasing the lid 121 to the closed position, so as to prevent the lid 121 from unnecessarily opening. For example, the urging member 150 may be formed of a torsion spring wound around the swing shaft of the cover 121 so as to apply an upward swinging-direction urging force to the cover 121.
The dust 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 includes 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 therethrough on the one hand and traps dust contained in the air on the other hand. As a result, dust sucked up by the suction force 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 in the vertical direction below the dust storage chamber 152, and forms a flow path through which dust flows when the cleaner 100 is in use. The suction pipe 113 is fixed to the housing 111, and when the cleaner body 110 is tilted rearward from the upright posture (posture shown in fig. 1), it is tilted rearward together with the housing 111. When the cleaner body 110 is in the upright posture, the lower end of the suction pipe 113 is brought into contact with the bottom 134 of the nozzle housing 132. That is, when the cleaner body 110 is in the upright posture, the lower end of the suction pipe 113 is closed based on the bottom 134 of the suction nozzle housing 132. When the cleaner body 110 is tilted rearward from the upright posture, the lower end of the suction pipe 113 moves in the direction indicated by the arrow a in fig. 1. As a result, the internal space of the suction pipe 113 is in communication with the suction space 131 of the nozzle housing 132.
A check valve 114 closing the upper end of the suction pipe 113 when the suction fan 116 is not operated is installed at the upper end of the suction pipe 113. In detail, only the rear end portion of the check valve 114 is fixed to the suction pipe 113, and the remaining portion is allowed to be in a state of being separated from the upper end of the suction pipe 113 when receiving the upward suction force of the suction fan 116. The check valve 114 may also be formed, for example, from a thin rubber sheet. In this case, when the suction fan 116 is operated, the check valve 114 is bent upward by the upward suction force of the suction fan 116, and the opening at the upper end of the suction pipe 113 can be opened.
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 rotate based on the motor to generate an upward air flow.

The recovery device 200 includes: a frame 210; a frame 210 is mounted at the front and a base plate 220 of the cleaner 100 can be mounted at the rear. A dust flow path 230 having one end opened to the outside of the housing 210 is provided in the housing 210 of the recovery device 200 so as to allow dust in the dust storage chamber 152 of the dust collector 100 to flow in. A dust storage portion 240 for storing dust collected via the dust flow path 230 is connected to the other end portion of the dust flow path 230. A suction source 250 that generates a suction force for sucking dust in the dust storage chamber 152 and also generates a suction airflow for transporting the dust to the dust storage portion 240 is disposed below the dust storage portion 240. Further, a deodorizing unit 270 for deodorizing the dust stored in the dust storage unit 240 is provided at the rear side of the suction source 250. In order to control the deodorizing treatment unit 270 and the suction source 250, a control unit 260 is disposed below the suction source 250.
As shown in fig. 5, the housing 210 includes: an upper portion 212 having a rear wall 214 abutting against the cleaner body 110 when the cleaner 100 is mounted; a lower portion 211 formed smaller in the front-rear direction than the upper portion 212.
In detail, as shown in fig. 5, the upper portion 212 is formed to form an inner space having a substantially rectangular shape in a plan view, and includes a rear wall 214, a front wall 217, a right wall 218, and a left wall 219. The dust flow path 230, the dust storage portion 240, the suction source 250, and the deodorizing treatment portion 270 are housed in the inner space of the upper portion 212. In a state where the upper portion 212 is in contact with the cleaner body 110, the dust flow path 230 communicates with the dust storage chamber 152 of the cleaner 100. The lower portion 211 is recessed forward relative to the rear wall 214 of the upper portion 212, and a receiving space 213 for receiving the suction nozzle 130 is formed behind the lower portion 211. A control unit 260 is disposed in the lower portion 211.
A rear wall 214 of the upper portion 212 is provided with a recess 215 for connecting the cleaner body 110. The recess 215 has a cross-sectional shape complementary to the front portion of the cleaner body 110 on the rear wall 214, and extends in the up-down direction as shown in fig. 6. The front portion of the cleaner body 110 in the upright posture is fitted into the groove portion 215. In this state, the cleaner body 110 is positioned in the width direction (left-right direction) of the groove portion 215 based on fitting in the groove portion 215.
As shown in fig. 6, the rear wall 214 is formed with a recovery port 216 of a rectangular shape in the groove portion 215. The recovery port 216 is formed in: when the cleaner body 110 is in the upright posture and the front portion of the cleaner body 110 is fitted into the recess 215 while the cleaner 100 is mounted on the base plate 220, the position overlapping the dust discharge port 124 shown in fig. 3 in the front-rear direction is set. That is, the recovery port 216 faces the dust discharge port 124 of the cleaner 100 when the cleaner 100 is mounted to the recovery apparatus 200. The recovery port 216 has a size that allows the cover 121 to enter the recovery port 216 when the cover 121 of the 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 so as to protrude from the outer side surface of the rear wall 214 through the small holes, respectively. These detection pieces 261 are used to detect the fitting of the cleaner body 110 into the groove portion 215.
The detection piece 261 is biased in a direction protruding from the rear wall 214, and is pushed into the small hole by the cleaner body 110 when the cleaner body 110 is fitted into the groove 215, so as to be immersed in the small hole. A signal generating unit 262 configured to detect whether or not the detection piece 261 is in a state of being immersed in the small hole and generate an activation signal when the detection piece 261 is detected to be immersed in the small hole is disposed in the housing 210. The signal generating unit 262 is electrically connected to the control unit 260 shown in fig. 1.
As shown in fig. 1, the dust flow path 230 is disposed in the upper portion 212 of the housing 210. The dust flow path 230 has: a lower flow passage 231 having the recovery port 216 described above; an upper flow path 232 which is disposed at a position higher than the lower flow path 231 and is connected to the dust storage portion 240. An intermediate flow path 233 extending in the up-down direction 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 intermediate flow path 233. An ion inlet 271 through which ions for deodorizing dust in the dust storage portion 240 flow is formed in the intermediate flow path 233.
The dust storage part 240 has a larger volume than the dust storage chamber 152 of the cleaner 100. As shown in fig. 5, the dust storage portion 240 is configured to form a space having a rectangular shape in 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. The rear wall 241 is provided with an opening to which the upper flow path 232 of the dust flow path 230 is connected. A circular opening is formed in the bottom wall 245, and a dust filter 247 is attached to the opening. The dust removal filter 247 is configured to trap dust on the one hand and allow air to pass through on the other hand.
A suction source 250 is disposed below the dust filter 247, and the suction source 250 is configured to suck air in the dust storage portion 240 through the dust filter 247. The suction force of the suction source 250 acts on the cover 121 of the cleaner 100 through the dust storage 240 and the dust flow path 230 when the cleaner 100 is mounted to the collecting device 200. The suction source 250 is configured to tilt the cover 121 from the closed position to the open position against the biasing force of the biasing member 150 and to obtain a suction force of a magnitude that sucks dust in the dust storage chamber 152. For example, the suction source 250 may be provided with a fan and a motor for rotationally driving the fan.
(deodorization treatment section of recovery apparatus)
A deodorizing treatment unit 270 for deodorizing the dust in the dust storage unit 240 is provided near the lower flow path 231 of the dust flow path 230. As shown in fig. 7, the deodorizing treatment unit 270 includes an ion flow path 272 through which ions for deodorizing dust flow. The ion flow channel 272 includes: an upstream end 273 provided below the lower flow path 231 of the dust flow path 230; a downstream end 275 connected to the ion inflow port 271 of the dust flow path 230; an intermediate portion 277 connecting the upstream end 273 with the downstream end 275.
The upstream end portion 273 forms a flow path extending in the left-right direction, and an ion supply portion 274 for generating a supply air flow for supplying ions to the dust storage portion 240 is arranged at the upstream end portion 273. Since ions are lighter than dust, the ion supply unit 274 is configured to operate with less power consumption than the suction source 250 for sucking dust. For example, the ion supply unit 274 may include: a fan; and a motor for rotating the driving fan with lower power consumption than the motor of the suction source 250.
The intermediate 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 intermediate portion 277 is connected to the downstream end portion 275. The flow path cross section of the junction of the intermediate portion 277 and the downstream end portion 275 is narrower than the flow path cross section elsewhere in the ion flow path 272.
The downstream end portion 275 forms a flow path extending obliquely upward from the upper end of the intermediate portion 277 toward the ion inflow port 271. A valve body 276 for opening and closing the ion flow passage 272 is housed in the downstream end 275 of the ion flow passage 272. In the present embodiment, a ball valve is used as the valve body 276. The valve body 276 shown in fig. 7 is positioned to close the upper end of the intermediate portion 277, and in the following description, the position of the valve body 276 shown in fig. 7 is referred to as a "closed position". Further, the valve body 276 is formed to be lightweight and to the extent that it can float based on the supply air flow generated by the ion supply portion 274.
As shown in fig. 8, an ion release tube 280 protruding from the side wall of the upstream end 273 toward the inside of the ion flow channel 272 is provided at the upstream end 273 of the ion flow channel 272. An ion generating cassette 281 is fixed to an outer surface of the ion flow passage 272. An ion generating portion 282 configured to release ions into the ion flow path 272 via the ion release cylinder 280 is disposed in the ion generation cartridge 281.
The ion generating unit 282 includes: a rod-shaped discharge electrode 283 arranged substantially coaxially with the ion release tube 280; an annular counter electrode 284 disposed between the discharge electrode 283 and the ion discharge tube 280 so as to face the discharge electrode 283. The voltage applying unit 285 is connected to the discharge electrode 283, and a voltage is applied to the discharge electrode 283 by the voltage applying unit 285. The counter electrode 284 is fixed in the ion generating cassette 281 in a grounded state, and when a voltage is applied to the discharge electrode 283 by the voltage applying unit 285, a potential difference is generated between the discharge electrode 283 and the counter electrode 284, and a discharge is generated therebetween. Ions are generated based on the discharge.
The voltage applying unit 285 of the ion generating unit 282, the ion supplying unit 274, and the pumping source 250 are electrically connected to the control unit 260, and are controlled by the control unit 260.
(description of operation)
When the suction fan 116 of the cleaner 100 is operated during cleaning, the check valve 114 is opened based on the suction force generated by the suction fan 116, and dust on the floor is sucked into the dust storage chamber 152 via the suction nozzle 130 and the suction pipe 113. The dust flowing into the dust storage chamber 152 is trapped by the dust storage filter 115. When the cleaning operation is completed, the suction fan 116 of the cleaner 100 is stopped, and the check valve 114 closes the upper end of the suction pipe 113. Therefore, the dust collected by the dust storage filter 115 does not fall down to the suction pipe 113 and stays in the dust storage chamber 152.
In order to collect dust stored in the dust storage chamber 152 of the dust collector 100, the dust collector 100 is mounted to the collecting device 200. Specifically, the cleaner 100 is placed on the base plate 220 of the recovery apparatus 200 in a state where the cleaner body 110 and the grip 140 are in an upright posture. When the cleaner body 110 in the upright posture is fitted into the recess 215 of the recovery device 200, the lid 121 of the cleaner 100 and the recovery port 216 of the recovery device 200 face each other in the front-rear direction. In this state, the detection piece 261 of the recovery device 200 is pushed forward by the cleaner body 110, and the detection piece 261 is immersed in the small hole of the rear wall 214.
The detection piece 261 is immersed in the small hole, and is detected by the signal generating unit 262. The signal generating unit 262 generates an activation signal based on the detection of the sinking of the detection piece 261 into the hole. The start 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 time in response to the reception of the start signal.
When the suction source 250 is operated, the suction force of the suction source 250 acts on the cover 121 facing the recovery port 216 via the dust storage portion 240 and the dust flow path 230. The cover 121 is tilted downward from the closed position closing the dust discharge port 124 as shown in fig. 3 by receiving the suction force of the suction source 250 to an open position opening the dust discharge port 124, and the dust discharge port 124 is opened. As a result, the dust chamber 152 of the cleaner 100 communicates with the inner space of the dust storage 240 via the dust flow path 230. In this state, a suction airflow is generated to cause dust in the dust storage chamber 152 of the dust collector 100 to flow into the dust flow path 230, and the dust in the dust storage chamber 152 flows into the dust flow path 230 by the suction airflow and flows into the dust storage portion 240 of the recovery device 200. In the dust storage portion 240, dust is captured by the dust removal filter 247, and stored in the dust storage portion 240.
During operation of the suction source 250, the valve body 276 disposed at the downstream end 275 of the ion flow channel 272 connected to the dust flow channel 230 is held at the closed position by gravity. Therefore, the suction air flow does not flow to the ion flow channel 272 but flows toward the dust storage portion 240.
When the operation time of the suction source 250 is completed, the control unit 260 stops the suction source 250. As a result of the suction source 250 being stopped, the suction force acting on the cover 121 of the cleaner 100 is lost, and the cover 121 returns to the closed position by the urging member 150. When the cover 121 returns to the closed position, the dust discharge port 124 of the cleaner 100 is closed. At this time, as shown in fig. 1, the recovery port 216 of the recovery device 200 is also closed by the cover 121.
The dust storage portion 240 has a larger volume than the dust storage chamber 152 of the cleaner 100, and can store a large amount of dust. When a large amount of dust is accumulated in the dust storage portion 240, odor generated from the dust may become a problem. In order to suppress odor generated from dust, the control unit 260 operates the ion generating unit 282 and the ion supplying unit 274 after the suction source 250 is stopped. The control unit 260 operates the ion generating unit 282 and the ion supplying unit 274 for a period of time (for example, about 3 hours) for which it is considered that a sufficient deodorizing effect can be obtained for the dust in the dust storage unit 240. The operation time of the ion generating portion 282 and the ion supplying portion 274 is longer than the time required for the suction source 250 to collect dust from the cleaner 100 (i.e., the operation time of the suction source 250).
When the ion generating unit 282 operates, the voltage applying unit 285 applies a voltage to the discharge electrode 283. As a result, a potential difference is generated between the discharge electrode 283 and the counter electrode 284. Based on this potential difference, a discharge is generated between the discharge electrode 283 and the counter electrode 284. Ions are generated based on the discharge. Ions are released into the ion flow channel 272 via the ion release tube 280 by a potential of discharge between the discharge electrode 283 and the counter electrode 284.
At this time, the ion supply portion 274 generates a supply air flow. As shown in fig. 9, the supply air flows to float the valve body 276. That is, the valve body 276 moves to an open position that opens the ion flow channel 272. As a result, the upper end of the intermediate portion 277 of the ion flow passage 272 is opened, and a flow passage for supplying ions released into the ion flow passage 272 to the dust flow passage 230 is opened. Ions flow into the dust flow path 230 through the ion inlet 271 together with a supply air flow (see an arrow in fig. 9) flowing through the ion flow path 272. At this time, the collection port 216 of the dust flow path 230 is closed by the cover 121 of the cleaner 100, and therefore, the supply air flow flowing into the dust flow path 230 flows toward the dust storage 240. Ions reach the dust storage part 240 based on the supply air flow flowing toward the dust storage part 240, and the dust in the dust storage part 240 is deodorized.
In the above-described embodiment, the ions are carried to the dust storage portion 240 not based on the suction air flow generated by the suction source 250 for collecting dust from the dust collector 100 but based on the supply air flow generated by the ion supply portion 274 separately provided from the suction source 250. Since the ion supply portion 274 generates the supply air flow with less power consumption than the suction source 250, the power consumption does not become excessive even if the ion supply portion 274 operates for a long time.
Since the supply air flow is generated with small power consumption, the suction air flow generated with relatively large power consumption becomes weaker than that. However, since the ions carried by the supply air flow are lighter than the dust carried by the suction air flow, they can be carried to the dust storage portion 240 even with a weaker supply air flow.
Since the ions carried by the supply air flow are used to deodorize the dust carried by the suction air flow to the dust storage portion 240, the generation timing of the supply air flow is set after the generation timing of the suction air flow. That is, the operation time of the ion supply unit 274 is set to be after the operation time of the pumping source 250, and these operation times do not overlap in time. Since the ion supply unit 274 and the suction source 250 do not operate simultaneously, the peak value of the consumed power of the recovery device 200 can be suppressed.
By shifting the operation time of the ion supply unit 274 and the suction source 250, the supply air flow for ion transportation and the suction air flow for dust transportation do not obstruct the flow of each other. Therefore, a piping structure connecting the ion flow path 272 to the dust flow path 230 is allowed. By adopting such a piping structure, a part of the dust flow path 230 (that is, a flow path section of the dust flow path 230 from the ion inlet 271 to the dust storage 240) can be used for both ion transport and dust transport. In this case, compared with a recovery device having a structure in which the ion flow channel 272 extends from the ion supply unit 274 to the dust storage unit 240, the recovery device 200 can be miniaturized.
In the above-described embodiment, in order to prevent the suction air flow from flowing from the dust flow path 230 to the ion flow path 272 via the ion inlet 271, the valve body 276 is disposed at the downstream end 275 of the ion flow path 272. The valve body 276 is held at a closed position closing the upper end of the intermediate portion 277 of the ion flow passage 272 by the action of gravity while the suction airflow flows in the dust flow passage 230. Therefore, the suction gas flow does not flow into the ion flow channel 272. On the other hand, when the supply air flow for ion transport is generated by the ion supply portion 274, the valve body 276 floats up by the supply air flow, and the upper end of the intermediate portion 277 of the ion flow channel 272 is opened. As a result, ions pass through the ion flow path 272 and the dust flow path 230 in this order, and reach the dust storage portion 240. Thus, no electrical control is required for opening and closing the valve body 276.
In the above embodiment, a ball valve is used as the valve body 276. Alternatively, the valve body 276 may be configured to employ a thin plate-like valve member. Alternatively, a solenoid valve may be used as the valve body 276, but electrical control may be required.
In the above-described embodiment, the valve body 276 is disposed at the downstream end 275 of the ion flow channel 272. Alternatively, the valve body 276 may be disposed at the middle portion 277 or the upstream end portion 273 of the ion flow channel 272.
In the above embodiment, the ion flow passage 272 is connected to the dust flow passage 230. Alternatively, the ion flow channel 272 may be connected to the dust storage portion 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 is stopped. However, the present invention is not limited thereto, and the control unit 260 may cause the ion supply unit 274 and the ion generation unit 282 to operate periodically.
In the above embodiment, the dust collecting device is configured as the recovery device 200 that recovers dust from the dust collector 100. Alternatively, the dust collecting device may be constructed as the dust collector 100. In this case, as shown in fig. 10, the deodorizing treatment part 270 may be formed at the periphery of the suction pipe 113 of the cleaner 100.
For example, the ion inflow port 271 may be provided to the suction pipe 113. The ion flow channel 272 may be connected to the suction pipe 113 at the ion inflow port 271 and may extend downward. An ion supply 274 may be provided at a lower end of the ion flow channel 272 to generate an upward supply air flow, and a valve body 276 may be provided at a downstream end 275 of the ion flow channel 272. Further, the ion generating portion 282 may be configured to release ions in the ion flow channel 272 in an upper side of the ion supplying portion 274. The voltage applying unit 285 of the ion supply unit 274 and the ion generating unit 282 may be connected to the control unit 263.
The control unit 263 may be connected to a posture sensor 264 that can detect whether the cleaner body 110 of the cleaner 100 is in an upright posture or in a tilted posture after tilting 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 the upright posture.
When the cleaner body 110 is in the upright posture, the lower end of the suction pipe 113 is closed by the bottom 134 of the nozzle housing 132 of the nozzle 130. In this state, if the ion supply unit 274 generates a supply air flow, the supply air flow flows into the suction tube 113 through the ion inflow port 271 and flows upward. The upward flow of the supply air 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 portion). During this time, if the ion generating portion 282 releases ions into the ion flow channel 272, the ions flow into the dust storage chamber 152 (dust storage portion) by the supplied air flow, and the dust in the dust storage chamber 152 (dust storage portion) is deodorized.
The deodorizing treatment portion 270 shown in fig. 10 is provided in the stick-type vacuum cleaner 100. Alternatively, the deodorizing treatment unit 270 may be incorporated in a cylinder type cleaner.
(effects etc.)
The dust collecting device according to the above embodiment has the following features and the following effects.
One aspect of the above embodiment relates to a dust collecting device including: a suction source that generates a suction force for sucking dust and generates a suction airflow for transporting the dust; a dust storage unit for storing dust conveyed by the suction airflow; an ion generating unit that generates ions; and an ion supply unit that generates a supply air flow for supplying ions generated by the ion generation unit to the dust storage unit, with power consumption smaller than that of the suction source.
According to the above configuration, in order to send the ions into the dust storage portion, the ions can be sent into the dust storage portion by the supply air flow generated by the ion supply portion, and the air flow as strong as the suction air flow generated by the suction source for transporting the dust can be omitted. Accordingly, the ion supply portion can be configured to generate the supply air flow with less power consumption than that of the suction source. Therefore, in order to obtain the deodorizing effect on dust, the consumed power of the dust collecting device does not become excessive even if the ion supply unit is operated for a long time.
In the above configuration, the dust collecting device may further include: and a control unit for controlling 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, the control unit stops the pumping source and then operates the ion supply unit and the ion generation unit, so that the ion supply unit and the ion generation unit do not operate simultaneously with the pumping source. Therefore, the peak value of the consumed electric power of the dust collecting device can be suppressed.
In the above configuration, the dust collecting device may further include: a dust flow path connected to the dust storage part so that the suction air flows to the dust storage part; and an ion flow path extending from the ion supply unit so as to allow the supply air flow. The ion flow path may be connected to the dust flow path so that the supplied air flow flows from the ion flow path into the dust storage portion via a part of the dust flow path.
According to the above configuration, the ion flow path is connected to the dust flow path so that the supply air flow flows from the ion flow path to the dust storage portion via a part of the dust flow path, and therefore, a part of the flow path for supplying ions to the dust storage portion can use the dust flow path. Therefore, compared with a structure in which the ion flow path is connected to the dust storage portion independently of the dust flow path, the dust collection device can be miniaturized.
In the above configuration, the dust collecting device may further include: a dust flow path connected to the dust storage part so that the suction air flows to the dust storage part; an ion flow path extending from the ion supply unit so as to allow the supply air flow; and a valve body for opening and closing the ion flow passage. The ion flow path may be connected to the dust flow path so that the supplied air flow flows from the ion flow path into the dust storage portion via a part of the dust flow path. The valve body may be configured to be held in a closed position closing the ion flow passage when the ion supply section is not in operation, and to be displaced to an open position opening the ion flow passage based on the supplied air flow when the ion supply section is in operation.
According to the above configuration, the suction source is operated before the ion supply section is operated, and the suction airflow flows in the dust flow path. Although the ion flow path is connected to the dust flow path, the ion flow path is closed by the valve body at this time. Therefore, the suction air flow can flow into the dust storage portion without flowing into the ion flow path. Thereafter, if the ion supply section is operated, the valve body in the closed position is displaced to the open position based on the supply air flow, and the supply air flow can reach the dust storage section via the ion flow path.
In the above configuration, the dust collecting device may further include: and a control unit for controlling 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 a time set by operating the suction source.
According to the above configuration, the control unit operates the ion supply unit and the ion generation unit for a time longer than the time for operating the suction source, and therefore, can supply ions to the dust storage unit for a relatively long time. If ions are supplied to the dust storage part for a long time, dust in the dust storage part can be deodorized based on the ions.

The dust collecting device of the above embodiment can be suitably applied to a device used for cleaning work.
