Samsung patents vacuum dock that pushes cleaner off if it gets too hot

Samsung has patented a cordless vacuum system where the charging dock monitors the temperature of the charging contacts. If the temperature gets too high, the dock sends a signal to the vacuum to physically move away from the station to prevent overheating.

Why it mattersThis safety feature could prevent damage or fire risks by automatically separating the device from its charger when heat levels become unsafe.

In the filing’s own words

A cordless vacuum cleaner includes a cleaner main body and a station. The cleaner main body includes a battery and a first processor controlling performing a cleaning function using power of the battery. The station includes a power conversion device to generate a voltage to charge the battery of the cleaner main body, a second charge terminal to charge the battery of the cleaner main body with the voltage generated by the power conversion device, a temperature sensor installed within a distance from the second charge terminal and to detect a temperature of the second charge terminal, a divider resistor to provide a voltage by dividing of an input voltage with the temperature sensor, and a second processor controlling performing an overheating prevention operation based on a voltage level of the voltage provided by the divider resistor and the temperature sensor being greater than a threshold voltage level.

What exactly they claim (claim 1)

1. A cordless vacuum cleaner comprising: a cleaner main body; and a station, wherein the cleaner main body comprises: a battery; a first charge terminal configured to charge the battery; a first communication interface; and a first processor configured to control performing a cleaning function using power provided by the battery, and the station comprises: a power conversion device configured to generate a voltage to charge the battery of the cleaner main body; a second charge terminal configured to charge the battery of the cleaner main body with the voltage generated by the power conversion device; a temperature sensor installed within a certain distance from the second charge terminal and configured to detect a temperature of the second charge terminal; at least one divider resistor configured to provide a voltage by dividing an input voltage with the temperature sensor; a second communication interface configured to communicate with the first communication interface of the cleaner main body; and a second processor configured to control performing an overheating prevention operation based on a voltage level of the voltage provided by the at least one divider resistor and the temperature sensor being greater than a certain first threshold voltage level, wherein: the overheating prevention operation is an operation in which the second processor transmits an overheating notification to the first communication interface of the cleaner main body through the second communication interface, and the first processor is further configured to separate the cleaner main body from the station by a certain distance or more based on the overheating notification received through the first communication interface.
