[First embodiment]
FIG. 1 is a perspective view showing a cleaner according to the first embodiment. FIG. 2 is a cross-sectional view illustrating the cleaner according to the first embodiment. The cleaner 10, for example, cleans the window glass using a liquid such as a cleaning liquid, and then sucks and removes the liquid attached to the window glass, which is an example of the object. The cleaner 10 operates with power supplied from a DC power supply. In the present embodiment, the cleaner 10 operates by the electric power supplied from the power tool battery 100 used for the power tool.

  The cleaner 10 includes a case 20, a motor unit 30, a tank unit 40, a nozzle unit 50, a battery mounting unit 80, and a control circuit 90. The cleaner 10 may further include a power tool battery 100.

  The case 20 defines the outer shape of the cleaner 10. The case 20 is formed in a cylindrical shape. The case 20 houses the motor unit 30 and the control circuit 90 in an internal space. The case 20 has an accommodating portion 21 in which a tank unit 40 can be attached and detached at a front portion of an outer periphery. The nozzle unit 50 is connected to the upper part of the case 20. The case 20 has a battery mounting portion 80 disposed at a lower portion of the outer periphery. In the case 20, a handle 22 and a switch 23 are arranged.

  The handle 22 is a grip that is gripped by the user. The handle 22 is arranged at the rear of the case 20. The outer shape of the handle 22 is defined by the handle housing 221. The handle housing 221 is formed integrally with the case 20.

  The switch 23 is a switch operated by a user to drive or stop the cleaner 10. The switch 23 switches between driving and stopping the cleaner 10 each time the switch 23 is operated. The switch 23 is arranged at the front of the handle 22. The switch 23 is operable with the user holding the handle 22. The switch 23 includes a trigger operation member 231, an elastic member 232, and a trigger signal output unit 233.

  The trigger operation member 231 is arranged at the front of the handle 22. The trigger operation member 231 is arranged to be able to advance and retreat in an opening 222 formed in the handle housing 221. More specifically, at least a part of the trigger operation member 231 is disposed in the opening 222. At least a part of the trigger operation member 231 projects forward from the front surface of the handle housing 221. The trigger operation member 231 is a block-shaped member. The trigger operation member 231 has a front end surface 231a facing forward. In the Y-axis direction, the trigger operation member 231 is disposed at the center of the handle 22. In the Y-axis direction, the center of the trigger operation member 231 coincides with the center of the handle 22.

  The trigger operation member 231 is switched between start and stop of the motor 11 by being pulled into the opening 222. When the user releases his / her hand, the trigger operation member 231 returns to the original position by the elastic force of the elastic member 232.

  The elastic member 232 is disposed inside the handle housing 221. One end of the elastic member 232 in the axial direction is fixed inside the handle housing 221, and the other end is fixed to the trigger operation member 231. The elastic member 232 applies an urging force for returning the trigger operation member 231 pulled into the opening 222 to the original position. More specifically, the elastic member 232 contracts when the trigger operation member 231 is pulled into the opening 222, and urges the trigger operation member 231 forward.

  The trigger signal output unit 233 includes an electronic circuit that can output a trigger signal by operating the trigger operation member 231. The trigger signal output unit 233 is disposed inside the handle housing 221. The trigger signal is a command signal for starting the motor 11. The contact of the trigger signal output unit 233 turns ON when the retracted amount of the trigger operation member 231 is equal to or larger than the threshold. The contact of the trigger signal output unit 233 is turned off when the retracted amount of the trigger operation member 231 is less than the threshold. More specifically, the trigger signal output unit 233 outputs a command signal for driving the motor 11 when the retraction amount of the trigger operation member 231 is equal to or more than the threshold value, and drives the motor 11 when the retraction amount of the trigger operation member 231 is less than the threshold value. Stop the output of the command signal.

  When the trigger operation member 231 is pulled into the inside of the handle housing 221, the trigger operation member 231 contacts the trigger signal output unit 233, and the trigger signal output unit 233 outputs a trigger signal to the control circuit 90. When the operation of the trigger operation member 231 by the user is released, the trigger operation member 231 is separated from the trigger signal output unit 233 by the elastic force of the elastic member 232. When the trigger operation member 231 moves away from the trigger signal output unit 233, the output of the trigger signal from the trigger signal output unit 233 is stopped.

  The motor unit 30 is a drive source of the cleaner 10. More specifically, the motor unit 30 generates a flow of air that sucks the liquid attached to the window glass. The motor unit 30 includes a motor 31, an output shaft 32, and a fan 33.

  The motor 31 rotates a fan 33 for generating a suction force capable of sucking the liquid attached to the window glass. The motor 31 is rotated by electric power supplied from the power tool battery 100. The motor 31 is connected to a fan 33 via an output shaft 32. The motor 31 is disposed downstream of the fan 33 inside the case 20. The rotation of the motor 31 is controlled via a control circuit 90.

  The output shaft 32 transmits the rotational force of the motor 31 to the fan 33. The output shaft 32 is connected on the same axis as the rotation shaft of the motor 31.

  The fan 33 rotates in conjunction with the rotation of the motor 31 to generate a suction force capable of sucking the liquid attached to the window glass. The fan 33 generates a flow of air capable of sucking the liquid. The fan 33 is disposed downstream of the suction port 55 and upstream of the outlet 56. The fan 33 is arranged inside the case 20 on the upstream side of the motor 31. In the present embodiment, the fan 33 is a centrifugal fan. The fan 33 blows air outward in the radial direction. The fan 33 is connected to the rotation shaft of the motor 31 via the output shaft 32. The fan 33 rotates when the motor 31 rotates. When the fan 33 rotates, the liquid adhering to the window glass together with the air is sucked into the case 20 from the suction port 55.

  The tank unit 40 stores the sucked liquid. The tank unit 40 is disposed downstream of the fan 33 of the motor unit 30. The tank unit 40 is detachable from the storage section 21 of the case 20. The tank unit 40 has a box-shaped tank 41.

  The tank 41 stores a liquid. The tank 41 has an opening 411 at the top. The opening 411 communicates with the space inside the case 20. The tank unit 40 is disposed downstream of the suction port 55. By removing the tank 41 from the storage section 21, the stored liquid can be discharged. The tank 41 preferably has a backflow prevention mechanism to prevent the stored liquid from inadvertently flowing out.

  The nozzle unit 50 will be described with reference to FIGS. FIG. 3 is a perspective view showing a nozzle unit of the cleaner according to the first embodiment. FIG. 4 is a side view showing the tip of the nozzle unit of the cleaner according to the first embodiment. The nozzle unit 50 sucks the liquid attached to the window glass together with the air, and blows out the air to the window glass. The nozzle unit 50 is connected to an upper part of the case 20. The nozzle unit 50 has a head housing 51, a first wiper member (wiper member) 52, a second wiper member (wiper member) 53, a blowout guide member 54, a suction port 55, and a blowout port 56.

  The head housing 51 defines the outer shape of the nozzle unit 50. The head housing 51 is formed in a box shape extending in the left-right direction. Inside the head housing 51, a flow path 511 communicating with the suction port 55 and a flow path 512 communicating with the outlet 56 are formed. The flow path 511 and the flow path 512 are separated by a partition wall 513.

  The flow path 511 is defined by a part of the inner peripheral surface of the head housing 51 and the partition wall 513. The flow path 512 is defined by a part of the inner peripheral surface of the head housing 51 and the partition wall 513. The flow channel 512 is disposed above the flow channel 511 inside the head housing 51. The partition wall 513 is arranged along the direction of air flow.

  The first wiper member 52 is a guide for sucking the liquid collected by the second wiper member 53. The first wiper member 52 guides the collected liquid to the suction port 55. The first wiper member 52 is disposed on the periphery of the suction port 55 so as to face the second wiper member 53. The first wiper member 52 is arranged below the tip of the head housing 51. The first wiper member 52 is formed in a horizontally long plate shape. The first wiper member 52 has a longitudinal direction along the X-axis direction. The first wiper member 52 has an acute triangular cross-sectional shape when viewed in the X-axis direction. The first wiper member 52 is formed of an elastic body such as elastically deformable rubber. The first wiper member 52 is deformed when pressed against the window glass, and comes into close contact with the window glass.

  The second wiper member 53 is a wiper that wipes off the liquid attached to the window glass together with the first wiper member 52. The second wiper member 53 collects the liquid attached to the window glass and guides the collected liquid to the suction port 55. The second wiper member 53 is arranged on the peripheral edge opposite to the suction port 55 so as to face the first wiper member 52. The second wiper member 53 is disposed at an intermediate portion of the tip of the head housing 51. The second wiper member 53 is arranged at an interval from the first wiper member 52. The second wiper member 53 is formed in a horizontally long plate shape. The second wiper member 53 is formed of an elastic body such as elastically deformable rubber. The second wiper member 53 is deformed when pressed against the window glass and comes into close contact with the window glass. The space formed between the second wiper member 53 and the first wiper member 52 communicates with the suction port 55.

  The blowout guide member 54 is a guide plate that guides the air blown out to the window glass. The blow-out guide member 54 is arranged on the periphery of the blow-out port 56 so as to face the second wiper member 53 with a space therebetween. The blowout guide member 54 is arranged above the top end of the head housing 51. The blowing guide member 54 is formed in a horizontally long plate shape. The space formed between the outlet guide member 54 and the second wiper member 53 communicates with the outlet 56.

  It is preferable that the length d1 of the blowing guide member 54 from the tip of the head housing 51 is shorter than the length d2 of the second wiper member 53 from the tip of the head housing 51. Thereby, when the second wiper member 53 is pressed against the window glass and deformed, the possibility that the space between the blow-out guide member 54 and the second wiper member 53 is blocked is reduced.

  The suction port 55 is a suction port that sucks the liquid wiped by the first wiper member 52 and the second wiper member 53 together with air. The suction port 55 is a suction port of the fan 33. The suction port 55 is an opening formed at the tip of the head housing 51. The suction port 55 communicates with the flow path 511.

  The outlet 56 is an outlet that blows out air to the window glass. The outlet 56 is an exhaust port of the fan 33. The outlet 56 is an opening formed at the tip of the head housing 51. The outlet 56 communicates with the flow channel 512. The outlet 56 communicates with the suction port 55 inside the head housing 51.

  It is preferable that the nozzle unit 50 configured as described above is used in a posture in which the first wiper member 52 and the second wiper member 53 are lowered toward the suction port 55 from the front end that comes into contact with the window glass.

  Returning to FIG. 2, the flow path and the space formed inside the case 20 will be described. Inside the case 20, a partition wall 61, a partition wall 62, a partition wall 63, a guide plate 64, and a scattering prevention plate 65 are arranged, and these form a flow path and a space.

  The partition wall 61 defines a flow path 71 between the sucked air and the liquid inside the case 20. The partition wall 61 is arranged at an upper portion inside the case 20. The partition wall 61 is formed in a cylindrical shape. The axis of the partition wall 61 has a slope that decreases toward the rear side. The diameter of the partition wall 61 is increased from the upper end to the lower end. The upper end of the partition wall 61 is continuous with the wall defining the flow path 511 of the nozzle unit 50. The lower end of the partition wall 61 faces the fan 33. The partition wall 61 is arranged in a state where at least a part of the radial outside of the fan 33 is opened. The space inside the partition wall 61 becomes a flow path 71 communicating with the suction port 55 and the flow path 511. A space 72 is defined by the outer peripheral surface of the partition wall 61 and the inner peripheral surface of the case 20.

  The partition wall 62 defines a flow path 73 of the air blown out to the window glass inside the case 20. The partition wall 62 is disposed so as to face the upper portion of the inner peripheral surface of the case 20. The partition wall 62 is formed in a plate shape. The partition wall 62 is disposed at a distance of about several mm from the inner peripheral surface of the case 20. The upper end of the partition wall 62 is continuous with the wall defining the flow path 512 of the nozzle unit 50. The partition wall 62 has a lower end portion 621 located at an intermediate portion in the vertical direction inside the case 20. The space defined by the partition wall 62 and the inner peripheral surface of the case 20 is a flow path 73 communicating with the outlet 56 and the flow path 512. The space defined by the partition wall 62, the partition wall 63, the guide plate 64, and the scattering prevention plate 65 is a flow path 74 that connects the space 72 and the flow path 73.

  The partition wall 63 partitions the space in which the motor 31 is arranged from the flow path 73 and the flow path 74. The partition wall 63 is arranged at an intermediate rear portion of the case 20. The partition wall 63 faces the lower end 621 of the partition wall 62. The partition wall 63 is arranged apart from the lower end 621 of the partition wall 62. The partition wall 63 is formed in a plate shape. The partition wall 63 has a slope that decreases toward the rear side. The partition wall 63 has an upper end connected to the guide plate 64. The lower end of the partition wall 63 is connected to the inner peripheral surface of the case 20.

  The guide plate 64 guides the sucked liquid to the tank 41. The guide plate 64 separates a space in which the motor 31 is arranged and a space in which the fan 33 is arranged. The guide plate 64 is arranged so as to face the lower end of the partition wall 61. The guide plate 64 is arranged apart from the lower end of the partition wall 61. The guide plate 64 is arranged downstream of the fan 33. The guide plate 64 is disposed downstream of the outlet of the flow path 71. The guide plate 64 is formed in a plate shape. The guide plate 64 has a slope that decreases toward the front side. The guide plate 64 is inclined in a direction different from the flow direction of the flow path 71. In the present embodiment, the normal of the guide plate 64 is parallel to the flow direction of the flow path 71. The air and the liquid that have passed through the flow path 71 come into contact with the guide plate 64. The lower end of the guide plate 64 faces the opening 411 of the tank 41. The output shaft 32 penetrates the guide plate 64. A through hole formed in the guide plate 64 and through which the output shaft 32 passes is sealed. The guide plate 64 is provided with a scattering prevention plate 65 at the upper end.

  The scattering prevention plate 65 restricts the sucked liquid from scattering. The anti-scattering plate 65 is erected from the upper end of the guide plate 64 to the upper front. The scattering prevention plate 65 extends in a direction different from that of the guide plate 64. The scattering prevention plate 65 is separated from the lower end of the partition wall 61. The scattering prevention plate 65 is disposed outside the fan 33 in the radial direction. The scattering prevention plate 65 is formed in a plate shape. Of the air and liquid blown outward by the fan 33 in the radial direction, the splash prevention plate 65 comes into contact with the air blown upward. When the gas comes into contact with the scattering prevention plate 65, the gas flows around the scattering prevention plate 65 and flows to the flow path 73 via the flow path 74. Further, the liquid rebounds on the scattering prevention plate 65, falls downward, and flows into the tank 41.

  The channel 71, the space 72, the channel 73, and the channel 74 communicate with each other. The flow path 71 is a space inside the partition wall 61. The flow path 71 communicates with the suction port 55 and the flow path 511 of the head housing 51. In the flow channel 71, air and liquid that have been suctioned from the suction port 55 and passed through the flow channel 511 of the head housing 51 flow. The flow path 71 has a fan 33 disposed upstream.

  The space 72 is a space inside the case 20 outside the partition wall 61. In the space 72, air and liquid blown radially outward from the flow path 71 by the fan 33 pass. In the space 72, the air flows toward the flow path 73 by the flow of the air toward the outlet 56. In the space 72, the liquid flows downward into the tank 41.

  The flow path 73 is a space defined by the partition wall 62 and the inner peripheral surface of the case 20. In the flow path 73, air blown from the outlet 56 flows through the flow path 512 of the head housing 51. Air flows into the channel 73 from the channel 74. The flow path 73 is arranged downstream of the fan 33.

  The flow path 74 communicates the space 72 with the flow path 73. The flow path 74 has a labyrinth structure. In the flow path 74, air flowing toward the flow path 73 through the space 72 flows. The flow path 74 is disposed downstream of the space 72 and upstream of the flow path 73.

  The battery mounting unit 80 will be described with reference to FIG. FIG. 5 is a perspective view showing a battery mounting portion of the cleaner according to the first embodiment. The battery mounting section 80 is arranged at a lower rear portion of the outer periphery of the case 20. The battery mounting portion 80 is capable of attaching and detaching the battery 100 for the electric tool. The battery mounting section 80 has a function as an adapter for connecting the power tool battery 100 to the control circuit 90. When the power tool battery 100 is mounted on the battery mounting section 80, the power tool battery 100 and the control circuit 90 are electrically connected. The battery mounting section 80 has a mounting surface 81 on which the power tool battery 100 is mounted.

  The mounting surface 81 includes a lower surface of the battery mounting unit 80 facing downward. The battery mounting section 80 has a mounting terminal. The mounting terminal is arranged on the mounting surface 81 of the battery mounting section 80.

  The control circuit 90 will be described with reference to FIG. FIG. 6 is a block diagram showing a cleaner according to the first embodiment. The control circuit 90 controls the cleaner 10. The control circuit 90 includes a control circuit board and is disposed inside the case 20. The control circuit 90 includes a processor such as a CPU (Central Processing Unit), a main memory including a nonvolatile memory such as a ROM (Read Only Memory) and a volatile memory such as a RAM (Random Access Memory), and an input / output. And an interface including a circuit.

  The switch 23 and the motor 31 are connected to the control circuit 90. The control circuit 90 drives the motor 31 while the command signal for driving the motor 31 is output from the trigger signal output unit 233. The control circuit 90 stops the motor 31 when the output of the command signal for driving the motor 31 from the trigger signal output unit 233 is stopped. The control circuit 90 includes a power supply circuit that converts the voltage of the power tool battery 100 into a voltage suitable for the motor 31.

  The power tool battery 100 is a power source for a portable power tool. The power tool battery 100 includes a plurality of lithium ion battery cells that are electrically connected. The power tool battery 100 can be charged by a charger (not shown) and used repeatedly. The power tool battery 100 is detachable from the battery mounting portion 80 by sliding.

  The power tool battery 100 has a battery terminal. The battery terminal is arranged on the upper surface of the power tool battery 100. The power tool battery 100 has a raised portion 101 that protrudes upward at a rear portion of the power tool battery 100.

  The power tool battery 100 is detachable from the battery mounting unit 80. When the power tool battery 100 is mounted on the battery mounting portion 80, the power tool battery 100 is slid forward from behind the battery mounting portion 80 so that the upper surface of the power tool battery 100 and the mounting surface 81 face each other. . By sliding the power tool battery 100, the front part of the raised part 101 comes into contact with the front part of the battery mounting part 80. In addition, a battery claw 102 protruding from the upper surface of the power tool battery 100 is provided on the upper surface of the power tool battery 100. The battery claw 102 is urged upward by an elastic member. The battery claw 102 is inserted into a battery mounting recess 82 provided at the rear of the battery mounting section 80. Thereby, the power tool battery 100 and the battery mounting portion 80 are positioned, and the power tool battery 100 is mounted on the battery mounting portion 80.

  When the power tool battery 100 is mounted on the battery mounting portion 80, the upper surface of the power tool battery 100 and the mounting surface 81 face each other. In a state where the power tool battery 100 is mounted on the battery mounting portion 80, the battery terminal and the mounting terminal are connected. As a result, the power tool battery 100 and the battery mounting portion 80 are electrically connected.

  When removing the power tool battery 100 from the battery mounting section 80, the battery button 103 is operated. Battery button 103 is connected to an elastic member that biases battery claw 102. Therefore, when the battery button 103 is operated, the battery claw 102 is disengaged from the battery mounting concave portion 82, and the battery 100 for a power tool is released from the battery mounting portion 80. By sliding the power tool battery 100 forward from the battery mounting section 80, the power tool battery 100 is removed from the battery mounting section 80.

  Next, with reference to FIGS. 7 and 8, a description will be given of a usage method and an operation of the cleaner 10 configured as described above. FIG. 7 is a schematic diagram illustrating an example of a method of using the cleaner according to the first embodiment. FIG. 8 is a side view showing the tip of the nozzle unit when the cleaner according to the first embodiment is used. The description will be made on the assumption that the window glass has been cleaned by the user using a liquid such as a cleaning liquid.

  The user slides and attaches the charged power tool battery 100 to the battery mounting portion 80 of the cleaner 10.

  As shown in FIG. 7, the user holds the handle 22 of the cleaner 10 and faces the tip of the nozzle unit 50 to the window glass. More specifically, the user positions the cleaner 10 in the area where the liquid is desired to be removed from the window glass. The user presses the first wiper member 52 and the second wiper member 53 against the window glass in a posture in which the nozzle unit 50 is lowered toward the suction port 55 from the front end portion in contact with the window glass.

  The user pulls in the trigger operation member 231 to drive the motor 31 to rotate the fan 33. The cleaner 10 sucks the liquid attached to the window glass together with the air from the suction port 55. Further, the cleaner 10 blows air from the outlet 56 to the window glass.

  The user slides the cleaner 10 downward with the first wiper member 52 and the second wiper member 53 pressed against the window glass with the first wiper member 52 facing downward.

  As shown in FIG. 8, the liquid adhering to the window glass is wiped off by the first wiper member 52 and the second wiper member 53. More specifically, the liquid adhering to the window glass is collected by the second wiper member 53, and is wiped by the first wiper member 52 being guided to the suction port 55. The wiped liquid is sucked together with air from the suction port 55. Air is blown out from the outlet 56 to the portion of the window glass facing the outlet 56. Thereby, the surface of the window glass is dried. In addition, if the liquid adhering to the window glass remains without being sucked from the suction port 55, the liquid is removed by the blown air.

  The air and liquid sucked from the suction port 55 will be described. The air and the liquid sucked from the suction port 55 pass through the flow path 511 and the flow path 71. The air and the liquid are blown radially outward by the fan 33 near the outlet of the flow path 71. The liquid blown out by the fan 33 enters the tank 41 by its own weight or guided by the guide plate 64. Among the liquids blown out by the fan 33, the liquid blown upwards hits the scattering prevention plate 65 and is rebounded. The rebounded liquid enters the tank 41 by its own weight or guided by the guide plate 64. The air blown out by the fan 33 flows through the space 72 toward the flow path 74. The air that has flowed into the flow path 74 flows toward the flow path 73. In addition, even if the liquid flows into the flow path 74, the flow path 74 has a labyrinth structure, so that the liquid is prevented from entering the flow path 73. The air that has flowed into the flow path 73 passes through the flow path 512, is blown out from the outlet 56, and is exhausted.

  In this way, the user sucks and removes the liquid adhering to the window glass together with the air while slowly sliding the cleaner 10 along the window glass. By moving the cleaner 10 in this manner, after the liquid attached to the window glass is sucked in the portion facing the suction port 55, the surface of the window glass is dried by the air blown out from the outlet 56.

  By moving the cleaner 10 in the advancing direction in this manner, the user shifts the cleaner 10 to the window glass space where the liquid has not yet been removed. Then, the cleaner 10 is positioned at a portion where the liquid has not yet been removed, and the cleaner 10 is similarly moved downward from above to remove the liquid.

  As described above, according to this embodiment, the liquid attached to the window glass can be removed by suction together with the air. Further, according to the present embodiment, the surface of the window glass can be dried by the air blown out from the outlet 56 after the liquid attached to the window glass is sucked in the portion facing the suction port 55. . In this manner, the present embodiment can more reliably remove the liquid attached to the window glass.

  In the present embodiment, the exhaust air of the fan 33 is blown out from the outlet 56 toward the window glass. According to the present embodiment, the exhaust air of the fan 33 can be used for drying the window glass. According to the present embodiment, since the exhaust port of the fan 33 does not need to be disposed in the case 20, it is possible to restrict the exhaust air from being blown toward the user.

  In the present embodiment, a single fan 33 can generate a suction force for sucking the liquid attached to the window glass and supply air for drying the window glass. According to the present embodiment, the efficiency of liquid removal by the cleaner 10 can be improved.

  In the present embodiment, the air sucked from the suction port 55 and the liquid can be separated by the guide plate 64 and the scattering prevention plate 65. In the present embodiment, the splash prevention plate 65 can restrict the liquid from flowing through the flow path 74 and flowing into the flow path 73. In the present embodiment, since the flow path 74 has a labyrinth labyrinth structure, even if the liquid flows into the flow path 74, it can be restricted from flowing into the flow path 73.

  According to the present embodiment, the liquid sucked from the suction port 55 can be guided to the tank 41 by the guide plate 64.
