The invention is capable of other embodiments and of being practiced or of being carried out in various ways.

DETAILED DESCRIPTION

(14) FIG. 1 illustrates a drain cleaner 10 according to one embodiment. The illustrated drain cleaner 10 is a free standing drain cleaner 10. The drain cleaner 10 includes a base unit 14 having a frame 18, a motor 22, a drum 26, and a cable 30. The motor 22 and the drum 26 are supported by the frame 18. The cable 30 is at least partially housed in the drum 26, with a leading end 34 of the cable 30 extending outside of the drum 26. The drum 26 is rotatably supported by the frame 18 such that the drum 26 can rotate relative to the frame 18. In the illustrated embodiment, rotation of the drum 26 is driven by the motor 22, and rotation of the drum 26 causes the cable 30 to rotate. In addition to rotating, the cable 30 can also be displaced in an axial direction so that the cable 30 can be fed into the drain. Specifically, the leading end 34 of the cable 30 is fed into a drain to unclog the drain and remove debris. In the illustrated embodiment, the leading end 34 is manually guided into a drain by a user pulling the cable 30 out of the drum 26 and feeding the cable 30 into the drain. The leading end 34 of the cable 30 may include an auger head 38 or other tool attachment to help unclog the drain.

(15) As shown in FIGS. 2 and 3, the illustrated drain cleaner 10 is provided with a handle 42 disposed on the cable 30. In some embodiments, the handle 42 assists in rotating the cable 30 as well as guiding the cable 30 into the drain. Referring to FIGS. 4-11, the handle 42 has an elongated body 44 having an open section 46 and a partially closed section 50. The partially closed section 50 includes a channel 54 that leads to the open section 46. The open section 46 includes a U-shaped prong 58 with a through hole 60 that aligns with the channel 54. The handle 42 provides a passage 62 for the cable 30 to pass through. Specifically, the handle 42 engages with the cable 30 such that the cable 30 extends through the channel 54, across the open section 46, and through the hole 60 in the prong 58. A portion of the cable 30 is exposed within the channel 54 and the open section 46 to enable the user to pull or push the cable 30 into or out of the drain while grasping the handle 42.

(16) The handle 42 further includes an actuator 66 for starting and stopping rotation of the cable 30. Pressing on the actuator 66 will actuate the motor 22 to start rotating the drum 26 and the cable 30. Releasing the actuator 66 will stop rotation of the drum 26 and the cable 30. In the illustrated embodiment, the actuator 66 includes a first button 67 that when pressed rotates the drum 26 a first direction (e.g., clockwise) and a second button 68 that when pressed rotates the drum a second direction opposite the first direction (e.g., counter-clockwise) In the illustrated embodiment, the actuator 66 is disposed on the partially closed section 50 of the handle 42 along a bottom surface 70 of the handle 42. In other embodiments, the actuator 66 is disposed on a side surface 74 or a top surface 78 of the handle 42. The configuration of the handle 42 allows the user to control the rotation of the cable 30 while also pulling the cable 30 in an axial direction to feed the cable 30 into the drain. Specifically, the user may grasp the cable 30 with the same hand that engages the actuator 66 for controlling the cable 30 rotation. Additionally, the user may grasp the open section 46 of the handle 42 with a second hand to allow for two-handed extension and retraction of the cable 30.

(17) The handle 42 is moveable relative to the cable such that the cable 30 can slide through the passage 62 as the cable 30 is fed into the drain. In other words, the handle 42 can be positioned proximate the leading end 34 of the cable 30 when the cable 30 is retracted within the drum 22. The cable 30 can also slide through the passage 62 relative to the handle 42 as the leading end 34 is extended into the drain. The handle 42 is also movable with the cable 30 and with respect to the base unit 14. As shown in FIGS. 2 and 3, the handle 42 can move from a first position proximate the base unit 14 of the drain cleaner 10 (FIG. 2) to a second position away from the base unit 14 of the drain cleaner 10 (FIG. 3). Accordingly, the handle 42 allows for control of the motor 22 from a position that is remote from the base unit 14.

(18) With reference to FIG. 12, in some embodiments, the handle 42 communicates wirelessly with the motor 22 so that a wire or cord is not necessary when the handle 42 is in a position that is remote from the base unit 14. The handle 42 can communicate with the motor 22 via any known wireless communication, such as radio or optical transceivers, Bluetooth, WiFi, etc. As such, the handle 42 may support a first wireless communication device 82. Accordingly, the drain cleaner 10 may include a second wireless communication device 86 on the base unit 14 for receiving a signal from the first wireless communication device 82. In addition, the drain cleaner 10 may also include an indicator to indicate that the handle 42 is paired or in communication with the motor 22. For example, the drain cleaner 10 may include an LED light on one or both of the base unit 14 or the handle 42. The LED light may flash or light up when the handle 42 is wirelessly paired with the motor 22.

(19) With continued reference to FIG. 12, a first power source 90 is supported on the base unit 14. The first power source 90 is electrically coupled to the motor 22, a first processor 94, and the second wireless communication device 86. The first power source 90 may be a battery pack, such as a rechargeable power tool battery pack. Alternatively, the first power source 90 may include circuitry for receiving power from an external AC power source.

(20) The handle 42 includes a second power source 98 supported by the body 44 to provide power to the first wireless communication device 82, a second processor 102, and the actuator 66. The second power source 98 may be, for example, one or more batteries. In the illustrated embodiment, the handle 42 may include a battery receptacle 106 for receiving the batteries to power the handle 42. In some embodiments, the handle 42 may be hardwired to the base unit 14 to communicate with the motor 22 and/or for receiving AC power.

(21) In operation, when a user presses the actuator 66 on the handle 42, the first wireless communication device 82 sends a signal to the second communication device 86. The signal is interpreted by the first processor 94, and the first processor 94 instructs the motor 22 to actuate. If the first button 67 is pressed, the processor 94 instructs the motor 22 to rotate in a first direction. Alternatively, if the second button 68 is pressed, the processor 94 instructs the motor 22 to rotate in a second direction that is opposite the first direction.

(22) In some embodiments, the motor 22 can be actuated by other actuators. For example, the motor 22 is actuated by a foot pedal 110. Stepping down on the foot pedal 110 actuates the motor 22 to start rotating the drum 26, and thus, rotating the cable 30. When a user releases the pedal 110, the motor 22 will stop rotating the drum 26 and the cable 30 will stop spinning within the drain. The foot pedal 110 is located proximate to or remotely from the base unit 14. In some embodiments, the drain cleaner 10 includes a switch 114 located on the base unit 14 for actuating the motor 22. The drain cleaner 10 can include any combination of actuators including the handle 42, the foot pedal 110, and the switch 114 for actuating the motor 22. When the drain cleaner 10 includes more than one actuator, the drain cleaner 10 may further include a control switch 118 to changed modes of operation between the different actuators. For example, the control switch 118 is set to allow one of the actuators (e.g., the handle 42) to actuate the motor 22, while deactivating the other actuators (e.g., the foot pedal 110 and the switch 114 on the base unit 14).

(23) Additionally, in one embodiment, the drain cleaner 10 includes a braking mechanism that will actively stop the spinning of the cable 30 when the user discontinues pressing the actuator 66 to cause the cable 30 to stop spinning. In other words, rather than simply deactivating the motor 22 and allowing the drum 26 and cable 30 to stop spinning, the braking mechanism can actively slow down rotation of the drum 26 and the cable 30. The braking mechanism can include a mechanical brake, electrical motor 22 braking, or any other type of known braking mechanism.
