Description

BRIEF DESCRIPTION OF DRAWINGS

(1) FIG. 1A illustrates a robotic vacuum dustbin with the motor unit removed embodying features of the present invention.

(2) FIG. 1B illustrates the removed robotic vacuum motor unit embodying features of the present invention.

(3) FIG. 2 illustrates the installation of the motor and impeller unit into the dustbin and the dustbin into the robotic vacuum chassis embodying features of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

(4) The present invention will now be described in detail with reference to an embodiment thereof as illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps and/or structures have not been described in detail in order to not unnecessarily obscure the present invention.

(5) Various embodiments are described below, including methods and techniques. The disclosure described herein is directed generally to a utilitarian dustbin design for a robotic vacuum.

(6) As understood herein, the term “robotic vacuum” may be defined generally to include one or more autonomous devices having communication, mobility, vacuuming and/or processing elements. For example, a robotic vacuum may comprise a casing or shell, a chassis including a set of wheels, a motor to drive wheels, a receiver that acquires signals transmitted from, for example, a transmitting beacon, a processor, and/or controller that processes and/or controls motor and other robotic autonomous or cleaning operations, network or wireless communications, power management, etc., one or more clock or synchronizing devices, a vacuum motor to provide suction, a dustbin to store debris, a brush to facilitate collection of debris, and a means to spin the brush.

(7) Generally, a removable dustbin is provisioned with a removable motor unit disposed therein. It should be understood that the present invention has broad applicability and utility. Any embodiment discussed and identified as “preferred” is considered to be part of one of the best modes for carrying out the present invention. A robotic vacuum is used to illustrate one embodiment of the invention, however, the invention may be used for various robotic devices, such as robotic polishers that polish floors, robotic lawn mowers, and similar devices that operate autonomously. Additionally, unless otherwise noted, specifications are given for illustrative purposes and shall not be understood as limiting the possibilities of alternative examples.

(8) The present invention proposes a dustbin design for a robotic vacuum or other robotic device that both provides convenient access to the motor unit by housing it within the dustbin and is easily separated from the motor unit to facilitate the individual repair, servicing, or washing of the parts.

(9) Referring to FIG. 1A, a dustbin 100 for a robotic vacuum is illustrated. The dustbin comprises a window 101 for receiving debris; window releases 102 that allow the window to be opened when depressed; and a filter 103 that keeps vacuumed debris particles from entering the motor. The open space at the back of the dustbin is the motor compartment 104 where the vacuum's electric motor sits and pulls the air through the opening 105 in the bottom of the motor compartment area. A release button 106 releases the latch 107 that holds the motor in its compartment in the dustbin.

(10) Referring to FIG. 1B, the electric vacuum motor 109 is illustrated. Referring briefly to both FIGS. 1A and 1B, the electric vacuum motor 109 fits in the motor compartment 104 and may be ejected from the motor compartment when desired. Referring back to FIG. 1B, prongs 111 eject the motor from its compartment when it is released. The motor is powered by a battery in the chassis (not shown) through electrodes 110. An air filter 112 is provided behind the vacuum motor to filter the outtake air as it exits the vacuum. A latch 108 secures the dustbin to the chassis when the motor is in its compartment.

(11) When the electric vacuum motor is removed from the dustbin, the dustbin is free of electronic parts and thus may be immersed in water for cleaning. Removability of the motor also improves accessibility to the motor for repairs or replacement.

(12) Referring to FIG. 2, the installation of the vacuum motor 109 into the dustbin 100 and the dustbin 100 into the robot chassis 200 is illustrated. As depicted, the vacuum motor 109 is inserted into the compartment 104 in the dustbin first, then the dustbin 100 is inserted into the compartment 213 in the robot chassis 200.
