Description

  The present invention relates to a cleaning device, and more particularly to a suction cleaning module.

  With the rapid development of automation technology and artificial intelligence, robots are playing an increasingly important role in the human environment. In recent years, service robots have been rapidly developed mainly for cleaning robots. Cleaning robots are widely classified into industrial robots and home robots according to the International Robot Federation (IFR). In recent years, home floor cleaning robots (electric vacuum cleaners) have grown rapidly and have become mainstream products with annual production exceeding 2.5 million units in the market. The global production value of cleaning robots is estimated to increase 6-fold from US $ 300 million in 2007 to US $ 1.8 billion in 2014, which has a huge potential for development.

  One of the consideration items regarding the cleaning robot is the cleaning performance. This cleaning performance varies depending on the configuration of the brush and the vacuum module. If only the vacuum module is used, a larger suction force is required to suck the heavy granular powder particles, which increases power consumption and noise. In addition to the configuration using only the vacuum module, there is a configuration combining a brush module and a vacuum module. The brush module is used to collect granular powder particles such as dust and dust and guide them to the suction holes of the vacuum module for removing them by suction. However, even if a brush module is used, currently available vacuum cleaning devices still cannot operate with satisfactory cleaning performance while maintaining low power consumption and low noise.

  Patent Document 1 discloses one conventional automatic vacuum cleaner. This is an autonomous floor cleaning robot that can perform a floor cleaning operation using a vacuum module to assist the cleaning operation of the brush module while mainly using the brush module. In this autonomous floor cleaning robot, the dust cartridge and the fan blower are modularized and configured to be integrated in the rear part of the robot, and the dust cartridge is provided as a flat drawer in the autonomous floor cleaning robot housing. It is configured to be inserted. Further, in Patent Document 2, a user moves a first cleaning unit that performs an automatic cleaning operation while moving within the area to be cleaned, that is, a robot cleaner and an area to be cleaned coupled to the first cleaning unit. A robot cleaning system including a second cleaning unit that performs a manual cleaning operation, that is, a manual cleaner, is disclosed. The first cleaning unit has a dust outlet for delivering dust to the second cleaning unit, and is coupled to the second cleaning unit via the dust outlet. Therefore, the robot cleaning system can remove dust and debris collected in the robot cleaner during the manual cleaning operation without disassembling the robot cleaner. Patent Document 3 discloses a dust collector for an autonomous floor cleaning device. This is a container that is mounted in an air flow path that opens to the upper surface of the autonomous floor cleaning device. Since this air flow path is designed to be removable from the fan blower of the autonomous floor cleaning device, the entire dust collector can be taken out from the upper surface of the autonomous floor cleaning device.

  The present invention provides a smart suction cleaning module having an improved suction channel. This suction channel is disposed next to the dust collection space of the suction cleaning module, and can prevent a reduction in dust collection capacity due to a reduction in the suction force of the fan blower.

  The present invention provides a smart suction cleaning module characterized by an integrated configuration of a dust collection channel and a dust collector and a configuration in which an intelligent detection function is integrated into a very slim fan blower. With these configurations, since the rotation of the fan blower is controlled according to the function of the intelligent detection function, the suction force of the suction cleaning module related to the rotation speed of the fan blower can be controlled in an automatic and intelligent manner. Intelligent detection functions include dust concentration detection, detection of whether the dust collector is full, detection of whether the dust collector cover is closed, and detection of filter damage. That is, the fan blower has control hardware and control firmware for controlling the fan blower according to the detection result to change the rotation speed. For example, increasing the amount of granular powder particles present in the air stream increases the rotational speed of the fan blower and increases the suction force of the suction cleaning module. Also, the fan blower is stopped when the dust collector is full or the filter is damaged. In addition to the use of sensors such as an infrared sensor to realize the intelligent detection function, other sensors that can detect voltage / current fluctuations in the suction cleaning module can be used to reduce cleaning power with lower power consumption and noise. Used to improve.

  In addition, the present invention provides a smart suction cleaning module characterized by a configuration that allows the size to be flexibly adjusted while maintaining a smooth air flow in the dust collection channel. With this configuration, the size of the dust collector can be easily adjusted without having to redesign the dust collection channel to suit various vacuum cleaners. For this reason, the dust collection space of the dust collector can be maximized for various vacuum cleaners. Also, for convenience of use, the smart suction cleaning module of the present invention further comprises a quick cleanup structure and a modular suction inlet set. The quick clean-up structure and the dust collector provided with a lower opening or a drawer opening allow the user of the suction cleaning module to allow the granular powder particles to fall naturally from the dust collector with a simple operation I can do it. Therefore, it is not necessary to disassemble the entire suction cleaning module and dirty hands.

  In one embodiment, the present invention provides a suction cleaning module. The suction cleaning module is a second housing having a first housing and an outer shell connected to the bottom of the first housing and having a dust collection space, and a suction channel between the outer shell and the first housing.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

1A and 1B are a developed view and a three-dimensional view of the suction cleaning module according to the first embodiment of the present invention. 2A and 2B are a schematic view showing a cut surface of the suction cleaning module according to the first embodiment and a cross-sectional view of the suction cleaning module.
In the first embodiment, the suction cleaning module 2 includes a first housing 20, a third housing 21, a second housing 22, a fan blower 23, and an operating mechanism 24. The first housing 20 has a suction inlet 200 and a dust collection opening 202. The second housing 22 is connected to the bottom of the first housing 20 and has an outer shell portion and a dust collection space 224. A suction channel 26 is formed between the outer shell portion and the first housing 20, and the dust collection is performed. The space 224 communicates with the suction channel 26. The third housing 21 has a filtration outlet 201 and is coupled to the first housing 20 and the second housing 22. In the present embodiment, the first housing 20 and the third housing 21 are integrally formed. However, in another embodiment, the first housing 20 and the third housing 21 may be formed separately.

  As shown in FIGS. 2A and 2B, a filter 226 is disposed between the third housing 21 and the interfaces of the first and second housings 20 and 22. A groove 203 is formed in the first housing 20 above the filter 226, and a receiving groove 204 is formed in the second housing 22 below the filter 226. The filter 226 is fitted into the frame 25 and surrounded. The upper portion of the frame 25 is inserted into the groove 203, and the bottom portion of the frame 25 is received in the receiving groove 204 by inserting one or more protrusions 250 formed on the bottom portion of the frame 25 into the corresponding recess of the receiving groove 204. . In addition, arrangement | positioning of the filter 226 in the 1st housing 20 can be changed according to an actual requirement, and is not limited to this embodiment.

  The second housing 22 is pivotally coupled to the first housing 20 at a position corresponding to the dust collection opening 202 and selectively contacts the third housing 21 to close the dust collection opening 202 or open at a certain inclination angle. Can be driven to rotate. The dust collection opening 202 is located between the first housing 20 and the third housing 21. In the present embodiment, the second housing 22 includes a base panel 220, a front panel 221, a pair of side panels 222, and a pair of rotating shafts 223. The front panel 221 is connected to one side end of the base panel 220, and each side panel 222 is connected to the base panel 220 and the front panel 221 at two sides and is sandwiched between them. For this reason, a dust collection space 224 is formed in the second housing 22. Through holes 2220 are formed at positions corresponding to the rotation shafts 223 of the side panels 222, and the pair of rotation shafts 223 are fitted into the corresponding through holes 2220, so that the second housing 22 is attached to the housing. It can be connected to both sides in a pivotable manner. As shown in FIG. 1A, a part of each rotating shaft 223 protruding from the first housing 20 is further coupled to the power transmission component 225. In addition, although a pair of rotation axis | shaft 223 is shown by embodiment of FIG. 1A, it is not limited to this. In other embodiments, for example, only one pivot shaft may be fitted on one side of the housing. The power transmission component 225 used in this embodiment is a gear. In FIG. 2A, the front panel 221 has a flow guide surface 2210 that is located on one side of the suction inlet 200 and forms a dust collection channel 26 in the first housing 20. In the present embodiment, the flow guide surface is a curved surface, but is not limited to this, and may be any shape to form various dust collection channels. Since the dust collection channel 26 is formed in the first housing 20 using the second housing 22 and no additional parts are required, not only can the dust collection space of the second housing 22 be increased, Increased air flow smoothness.

  The fan blower 23 has an inlet 230 and an outlet 231, and is coupled to the third housing 21 so that the inlet 230 is disposed at a position corresponding to the filtered outlet 201. In the embodiment shown in FIG. 2A, the third housing 21 further has an inclined surface 211 at a position corresponding to the fan blower 23 in which the filtration outlet 201 is provided, and the inlet 230 is received in the filtration outlet 201. The fan blower 23 is inclined by an angle θ with respect to the horizontal plane. Since the fan blower 23 is inclined by the inclined surface 211, the inflow port 230 is positioned corresponding to the dust collection channel 26, and the air flow in the dust collection channel 26 directly flows into the inflow port 230 after passing through the filter 226. Thereby, the advancing path | route of the airflow in a suction cleaning module is shortened, and the suction loss by the conventional long flow path of a fan air blower can be avoided.

  An actuating mechanism 24 coupled to the first housing 20 can generate a movement that rotates the second housing 22. In the present embodiment, the operating mechanism 24 includes a pair of levers 240 that are slidably fitted in grooves 207 formed on the side surface of the first housing 20. Each lever 240 includes a rib 241 and a slot 242 formed on one side of the rib 241. A power output component 243 coupled to the power transmission component 225 is received in the slot 242. The power output component 243 is a linear gear. By pushing the pair of levers 240 downward and linearly moving the levers 240 downward, the power output component 243 is driven to move linearly and rotates the power transmission component 225. In this embodiment, a pair of levers 240 is used, but a single power output component 243 is driven using a single lever 240, and a single power transmission component 225 is moved to a single rotation shaft 223. May be selected to rotate around and close the dust collection opening 202 or open at a certain angle of inclination. A rod 244 is connected to the upper part of the lever 240 in order to improve the ease of operation of the operating mechanism 24 by the user. As a result, the user can apply force to the lever 240 without any difficulty. The rod 244 is not one of the essential components of the suction cleaning module of the present invention, and may be selectively used according to actual requirements.

  Please refer to FIG. 3A and FIG. 3B which are schematic views showing the operation of the second housing in the suction cleaning module according to the first embodiment of the present invention. As shown in FIG. 3A, when the lever 240 is pushed and not moved downward linearly, the dust collection opening 202 is blocked by the base panel 220 of the second housing 22. As soon as the lever 240 is pushed and moved linearly downward, the power output component 243 also moves downward in response to the downward movement of the lever 240, and the gear of the power output component 243 is the same as the gear of the power transmission component 225. Since it is meshed and engaged, the power transmission component 225 is driven to rotate counterclockwise. Due to the counterclockwise rotation of the power transmission component 225, the base panel 220 of the second housing 22 is tilted as shown in FIG. 3B, the dust collection opening 202 appears, and the dust and dust in the second housing 22 are naturally caused by gravity. Allow it to fall. By forming the downward opening in the second housing 22, not only the structure of the second housing 22 is simplified, but also the user of the suction cleaning module can easily remove the granular powder particles by pushing the lever 240. It is possible to fall naturally from the dust collector and is very convenient. Apparently, after the dust in the second housing 22 is thrown away, the second housing 22 rotates back to its original position by pulling the lever 240 upward. In other embodiments, an elastic member such as a spring may be used to provide power to return the lever 240 to its original position.

  As shown in FIGS. 1A and 2A, the cartridge base 27 having a slot 270 formed at a position corresponding to the suction inlet 200 is fitted into the suction inlet 200 of the first housing 20. The cartridge base 27 further includes a dust remover 271 and a flow guide 272. Note that when the dust collection opening 202 is closed by the second housing 22, the front panel 221 of the second housing 22 abuts against the cartridge base 27. In the present embodiment, the dust remover 271 and the flow guide 272 are inserted into the grooves on both sides of the slot 270, respectively. Further, the cartridge base 27 can be fixed to the housing 20 by two fixing panels 273 arranged on both sides thereof. The dust remover 271 is configured to stir the dust on the floor so that the dust is sucked into the suction cleaning module through the suction inlet 200. A flow guide 272 disposed on one side of the dust remover 271 is used to ensure that the dust that has been stirred is sucked into the suction inlet 200 without leakage. In the present embodiment, the dust remover 271 has a sawtooth structure. Further, since the cartridge base 27 can be removed and replaced, the user can select the cartridge base 27 having the specific dust remover 271 according to the material of the floor. For example, in the case of a wooden floor, the cartridge base 27 having a soft plastic dust remover 271 is selected, and in the case of a tile floor, the cartridge base 27 having a hard plastic dust remover 271 is selected. In the case of carpet cleaning, the cartridge base 27 having the brush-shaped dust remover 271 is selected. Therefore, the suction cleaning module of the present invention can be adapted to all kinds of floor cleaning by simply changing the cartridge base 27 according to the floor. The cartridge base 27 and the dust remover 271 can be selected according to actual requirements, and there are no restrictions.

  The first housing 20 further includes a sensor 206 for detecting the state of the second housing 22 at a position corresponding to the dust collection space 224. The sensor 206 is provided for detecting the state of the second housing 22. This state detection includes detection of whether the second housing 22 is in the closed position or the open position, or detection of whether the amount of dust accumulated in the second housing 22 exceeds a specific threshold value. When the amount of dust accumulated in the second housing 22 exceeds a specific threshold, the sensor 206 is covered with dust, so that an alarm signal can be issued to the control unit 28. When the dust collector is in the open position as shown in FIG. 2B, the sensor 206 is covered by the second housing 22, so that another alarm signal can be issued to the control unit 28. The control unit 28 instructs the alarm unit to issue an alarm according to the received alarm signal to inform the user that the second housing 22 is full or the second housing 22 is not properly closed.

  In the present embodiment, the control unit 28 is mounted on the fan blower 23. The control unit 28 can determine whether the dust accumulated in the second housing 22 has exceeded a specific threshold according to the received alarm signal. When the threshold value is exceeded, the control unit 28 instructs the alarm unit 280 to issue an alarm to notify the user, and at the same time, the fan blower 23 is stopped and the dust in the second housing 22 can be removed. The sensor 206 is not limited to this, but may be an infrared sensor. The alarm unit may be an audio device, a light emitting device, or the like. The first housing 20 further includes another sensor 208 for detecting the state of the filter 21 between the filter 226 and the fan blower 23. Sensor 208 is provided to detect whether filter 226 is damaged and may be a powder sensor. The sensor 208 transmits a detection signal to the control unit 28. The amount of dust present in the airflow passing by the sensor 208 increases significantly when the filter 226 is damaged, so an increase in dust concentration is detected and the detection result is shown in the signal from the sensor 208. Is recognized by the control unit 28. The controller 28 determines that the filter 226 is damaged as soon as the amount of dust present in the airflow passing by the sensor 208 for a specific period exceeds a specific threshold, and alerts the alarm unit 280. The fan blower 23 is stopped. The first housing 20 further includes a powder sensor 209 at a position corresponding to the suction inlet 200 for detecting the amount of dust entering the suction inlet 200 and emitting a dust concentration signal to the control unit 28 accordingly. Therefore, the control unit 28 can issue a control signal for adjusting the suction force of the suction cleaning module by controlling the rotational speed of the fan blower 23 according to the received dust concentration signal. Moreover, in order to implement | achieve smart control, the control part 28 is comprised so that the voltage / current fluctuation | variation of the fan air blower 23 may be detected and used as basic data for controlling the rotational speed of the fan air blower 23. Thereby, not only the cleaning performance of the present suction cleaning module is greatly improved, but also the suction cleaning module can operate with lower power consumption and lower noise.

  Please refer to FIG. 5, which is a schematic diagram showing a cut surface of an automatic vacuum cleaner using the suction cleaning module of the present invention. As shown in FIGS. 1A and 5, the automatic vacuum cleaner 3 has a case 30, and the suction cleaning module 2 is accommodated in the case 30. A control panel 31 is disposed on the surface of the case 30 and is used as an operation interface of the automatic vacuum cleaner 3 and for displaying alarm information regarding the suction cleaning module 2. The automatic vacuum cleaner 3 can be driven to move by drive wheels and idle wheels 32 according to a control signal from the control unit. Therefore, when the suction cleaning module 2 detects that the amount of dust has increased, the control unit issues a control signal for increasing the suction force of the suction cleaning module and automatically improves the cleaning performance. The vacuum cleaner 3 is controlled to reciprocate, that is, repeatedly move back and forth.

  Please refer to FIG. 6A and FIG. 6B which are a developed view and a three-dimensional view of the suction cleaning module according to the second embodiment of the present invention. The suction cleaning module of the second embodiment is basically the same as that illustrated in FIG. 1A, but the operating mechanism 29 of FIGS. 6A and 6B is different from the operating mechanism 24 of FIG. 1A. In the second embodiment, the actuation mechanism 29 includes a pair of levers 290 coupled to both sides of the first housing 20. Each lever 290 has a power output component 291 coupled to the power transmission component 225. Therefore, the lever 290 can be rotationally driven so that the power transmission component 225 performs a rotational motion for inclining the second housing 22. In the second embodiment, a pair of levers 290 are used, but a single power output component 291 is driven using a single lever 290 and a single power transmission component 225 is rotated by a single rotation. It may be selected to rotate around the axis 223 to close the dust collection opening 202 or to open at a certain tilt angle.

  Please refer to FIG. 7A and FIG. 7B, which are schematic diagrams showing the operation of the suction cleaning module according to the second embodiment of the present invention. As shown in FIG. 7A, when the lever 290 is not rotated, the dust collection opening 202 is closed by the base panel 220 of the second housing 22. On the other hand, as soon as the lever 290 is rotated clockwise, the power output component 291 rotates corresponding to the rotation of the lever 290, and the gear of the power output component 291 meshes with and engages with the gear of the power transmission component 225. Therefore, the power transmission component 225 is driven to rotate counterclockwise. As a result of the counterclockwise rotation of the power transmission component 225, the base panel 220 of the second housing 22 is tilted by a certain tilt angle as shown in FIG. Allow it to fall naturally due to gravity. Apparently, after the dust in the second housing 22 is thrown away, the second housing 22 rotates back to its original position by pulling the lever 290 counterclockwise. In other embodiments, an elastic member such as a spring may be used to provide power to return the lever 290 to its original position.

The fan blower 43 has an upper shell 434 and a lower shell 435, and the motor 430 and the fan 431 are accommodated in a space between these shells. The inlet 432 is located at a position corresponding to the filtration outlet 420. As shown in FIG. 8, a frame seat 46 for mounting the filter 460 is disposed at a position corresponding to the first housing on the surface of the second housing 41, and the suction inlet 440 is disposed in the first housing 40 in the suction channel 44. And the second housing 41. The suction inlet 440 of the suction channel 44 is designed such that the cartridge base 47 having the slot 470 is fitted at a position corresponding to the suction inlet 440. The cartridge base 47 further includes a dust remover 471 and a flow guide 472 on both sides of the slot 470, respectively. The structure of the cartridge base 47 is the same as that described in the above embodiment, and further description is omitted. Further, the power sensor 441, the dust collection state sensor 450, and the filter sensor 424 may be provided in the suction cleaning module 4. Since these operate in the same manner as the sensors 206, 209, and 208 described in the above embodiment, further description is omitted.

  As shown in FIGS. 8 and 9, a first opening 422 is formed at a position corresponding to the first housing 40 and the second housing 41 of the third housing 42. First retaining frames 423 are disposed on both sides of the first opening 422. In addition, the second housing 41 is formed in the dust collector 411 between the first housing 40 and the second housing 41, the channel panel 410 forming the shell, the dust collector 411 coupled to the channel panel 410, and the first housing 41. And a second retaining frame 412 that is disposed on both sides of the second opening 413 disposed corresponding to the opening 422 and is coupled to the first retaining frame 423. In the present embodiment, the second retaining frame 412 has a buckle slot 414 into which the protrusion 462 of the frame rack 461 is inserted. A plurality of ribs 463 that support the filter 460 can be formed on the frame rack 461. In addition, a handle 48 is formed in the first housing 40 in order to make it easy for the user to pull out the modularized parts of the first housing 40 and the second housing 41 from the third housing 42.

  Please refer to FIG. 10, which is a schematic diagram showing a method of fitting the suction cleaning module shown in FIG. 8 to the automatic vacuum cleaner. Similar to that shown in FIG. 5, the automatic vacuum cleaner 3 has a case 30 for accommodating the suction cleaning module 4. Moreover, the automatic vacuum cleaner 3 has a driving wheel and an idle wheel 32 and can be driven to move according to a control signal. When the suction cleaning module 4 detects a large amount of dust, it increases the suction force of the suction cleaning module 4 and instructs the automatic vacuum cleaner to move back and forth repeatedly to completely remove the dust. Please refer to FIG. 11, which is a schematic diagram showing a method of throwing away dust from the suction cleaning module shown in FIG. When the dust collected in the suction cleaning module 4 exceeds a specific amount, the user opens the case 30 of the automatic vacuum cleaner 3 and removes a modularized part composed of the first housing 40, the second housing 41, and the filter 460. The case 30 can be pulled upward. In addition, since the filter 460 is mounted on the frame rack 461, the user can easily remove the frame rack 461 from the second retaining frame 412 and discard dust from the second housing 41.
