CONTACTLESS CHARGER, PROGRAM THEREFOR, AND AUTOMOBILE EQUIPPED WITH SAME
First Claim
1. A contactless charger in which an upper surface of a body case is an installation plate, the contactless charger comprising:
- a position detector that is disposed on or below the installation plate, and detects a presence of a mobile device on the installation plate;
a foreign matter detector that detects a conductive foreign matter that is present on the installation plate; and
a controller that drives an alarm unit that emits an alarm to a user, based on detection results of the position detector and the foreign matter detector,wherein after the foreign matter detector detects the presence of the conductive foreign matter, if the position detector detects the mobile device, the controller drives the alarm unit.

Abstract
A position detection coil (14B) is disposed as a foreign matter detector that detects a state where a foreign matter is present on the upper surface of an installation plate (6). Further, the position detection coil (14B) and an alarm unit (43) that emits an alarm when detecting a foreign matter by the position detection coil (14B) are connected to a controller (10). The controller (10) is formed to alternately drive position detectors (both position detection coils (14A), (14B)) and the position detection coil (14B) alone (foreign matter detector), and drive the alarm unit (43) if the detection level that is detected by the position detection coil (14B) alone (foreign matter detector) is higher than a threshold.

5. A program causing a computer to execute:
-
a step of detecting a presence of a mobile device on an installation plate of a contactless charger; a step of detecting a conductive foreign matter that is present on the installation plate; and a step of emitting an alarm to a user, if the presence of the mobile device is detected in the position detection step, after the presence of the conductive foreign matter is detected in the foreign matter detection step.

7. A contactless charger of which body case includes an upper surface that is used as an installation plate, the contactless charger comprising:
-
a charging coil that is disposed below the installation plate; a position detector that is disposed on or below the installation plate, and detects the presence of a mobile device on the installation plate; a foreign matter detector that detects a conductive foreign matter that is present on the installation plate; and a controller that drives an alarm unit that emits an alarm to a user, based on detection results of the position detector and the foreign matter detector, wherein when a detection level detected by the position detector is lower than a first threshold, and a detection level detected by the foreign matter detector is higher than a second threshold, the controller drives the alarm unit. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
