A condensate passively flows from the distal end of the body to the proximal end of the body, such that the condensate flows past each of the plurality of dam members and each of the plurality of skimming members.

Abstract: A housing assembly includes a panel having a plurality of sub-panels including a first sub-panel and at least one second sub-panel, the first sub-panel being fitted with an electric control box of an air-conditioner outdoor for shielding the electric control box. According to the housing assembly provided in the present disclosure, when an electric control box is to be maintained, only the first sub-panel is removed to expose the electric control box, without removing two panels to expose the electric control box, thereby reducing the difficulty of electric control maintenance and improving the convenience of electric control maintenance.

Abstract: A refrigerator includes sequential interior lighting to dynamically vary the light level in a compartment of the refrigerator. At least one light of a plurality of lights in the compartment may be activated after activation of at least one other light of the plurality of lights upon opening of a door such that the brightness level in the compartment progressively increases after opening of the door, thereby enabling a user's eyes to better acclimate to the compartment illumination.

Abstract: A method and apparatus of a control knob for a cooking appliance. The control knob includes a safety feature or initiation step for operating one or more cooking elements of the cooking appliance.

Abstract: Provided is a floor brush assembly for a vacuum cleaner. The floor brush assembly includes a roller brush component and a driving mechanism. A roller brush body of the roller brush component is rotatably mounted in a sleeve. The roller brush body is provided with bristles arranged in an elongated shape to form a bristle portion. The sleeve of the roller brush component has an avoidance opening of an elongated shape, and the bristle portion and the avoidance opening are arranged to directly face towards each other in a radial direction of the roller brush body. A first driving member of the driving mechanism is configured to drive the roller brush body to rotate, and a second driving member is configured to drive the sleeve to rotate. The first driving member and the second driving member are eccentrically arranged to allow the bristle portion to be selectively extended or retracted through the avoidance opening.
