Abstract: A system adapted to detect rotation of at least two spray arms of a household appliance spaced along a longitudinal axis of the appliance includes a first detection magnet, a second detection magnet and a magnetic sensor. The first detection magnet is arranged on a first spray arm of the at least two spray arms. The second detection magnet is arranged on a second spray arm of the at least two spray arms. A magnetic field direction of the second detection magnet is different from a magnetic field direction of the first detection magnet. The magnetic sensor is arranged in the household appliance and is adapted to sense a motion status of the first detection magnet and the second detection magnet.

Abstract: A connector for electrical connection between a wire and a conductive load includes a housing and an elastic conductive component having a portion extending through the housing. The elastic conductive component is connectable to the wire. The elastic conductive component is movable up and down relative to the housing to connect with or separate from the conductive load, electrically connecting or disconnecting an electrical connection between the wire and the conductive load.

Abstract: A sensor module includes a housing having a first cavity and a second cavity that are in communication with each other, a liquid level sensing module mounted on the housing and sensing liquid level related information when liquid flows into the second cavity, a turbidity sensing module mounted on a section of the housing having the first cavity, and a temperature sensing module integrated with the turbidity sensing module and sensing temperature related information of the liquid when the liquid flows into the first cavity. The turbidity sensing module includes a light transmitting unit and a light receiving unit that are located on opposite sides of the first cavity to allow light emitted from the light transmitting unit to pass through the first cavity and to be received by the light receiving unit.

Abstract: An electrical apparatus comprises a main body, a pivotal part pivotally connected to the main body, a first coil mounted on the main body, and a second coil mounted on the pivotal part. The first coil at least partly passes through the second coil to form an electromagnetic coupling between the first coil and the second coil that wirelessly supplies power between the main body and the pivotal part.

Abstract: An electrical connection assembly includes a first electrical connection module configured to be mounted on a fixed member and a second electrical connection module configured to be mounted on a moving member. The first electrical connection module has a first terminal and a second terminal. The first electrical connection module has a normally open switch. The second electrical connection module has a first contact pad and a second contact pad configured to be electrically connected with the first terminal and the second terminal, respectively. The second electrical connection module has a switch controller adapted to drive the normally open switch to a closed state when the first contact pad and the second contact pad are moved to a contact position in which the first contact pad and the second contact pad are in electrical contact with the first terminal and the second terminal, respectively.

Abstract: A method of detecting a status of a home appliance control system comprises collecting communication data transmitted on a communication bus of the home appliance bus control system and judging in real-time and online whether the collected communication data meet a preset alarm condition. The collection of the communication data is terminated if the collected communication data meet the preset alarm condition and the collection of the communication data is continued if the collected communication data do not meet the preset alarm condition. The method further comprises graphically displaying the collected communication data to obtain an actual test diagram of the collected communication data and analyzing the collected communication data based on the actual test diagram of the collected communication data to obtain an analysis result.
