Self-propelled cleaner
First Claim
1. A self-propelled cleaner having a body with a cleaning mechanism with a suction motor for vacuuming up dust, and a drive mechanism with driving wheels at the left and right sides of the body whose rotation can be individually controlled for steering and driving the cleaner, comprising:
- a mapping processor which acquires and stores geographical information on a room to be cleaned during traveling around the room for cleaning it and acquires positional data on an alarm position, during traveling around the room, from a marker installed in a given place in the room which outputs positional data on a previously specified location, and adds it to the geographical information;
a gas sensor which detects a gas leak;
an alarm sounder which generates an alarm sound;
a wireless LAN communication device which can transmit given information to the outside through a wireless LAN;
a travel route calculation processor which calculates a travel route from the present position to the specified location; and
a gas leak alarm control processor which acquires the result of detection by the gas sensor in a predetermined standby position and upon detection of a gas leak, enables the travel route calculation processor to calculate a travel route and controls the drive mechanism to move the cleaner along the travel route to the specified location, allows the alarm sounder to generate an alarm sound through a speaker and sends an alarm message to the outside through the wireless LAN communication device.

Abstract
A conventional gas leak alarm system is installed in a fixed place of a kitchen or similar space and just generates an alarm sound. Therefore, only a person which is at home can hear an alarm sound which it generates and even a person at home may not be able to hear it if he/she is away from it. According to this invention, after movement to a standby position at step S440, a system judges whether there is a gas leak, according to the result of detection by a gas sensor. If there is a gas leak, it transmits a text mail to notify a predetermined destination (person) of occurrence of a gas leak and calculates a travel route to a specified first alarm position at steps S452 and S454; after movement along the travel route to the alarm position at step S456, an alarm sounder generates an alarm sound at step S458. After a preset time period, it moves to a specified second alarm position by taking a similar procedure at steps S462 to 466 and continues to generate an alarm sound. Then, it continues shuttling between the first and second alarm positions.
