Self-propelling cleaner

Abstract

When detecting suction of a lighted object such as a cigarette or a match, a self-propelling cleaner 1 sends it to a dust room 12 a by controlling a valve 8 a . The self-propelling cleaner 1 collects ordinary dust such as dust and wastepaper into a dust room 12 b by controlling the valve 8 a . Since a lighted object such as a cigarette and ordinary dust are thus sent to two different dust rooms in a discriminated manner, even if a lighted object such as a cigarette is sucked other dust in the dust room can be prevented from catching fire from it, whereby the self-propelling cleaner is made safer from suction of a lighted object.

1 . A self-propelling cleaner comprising: 
 a main body provided with a first and a second dust rooms for accommodating dust, the first dust room includes a box made of an inflammable material for accommodating the dust;    a self-propelling section that propels the main body;    a sucking section provided with a suction mouth and a suction fan, and collects into one of the first and second dust rooms dust that is sucked through the suction mouth by rotating the suction fan;    a cleaning section that controls the self-propelling section and the sucking section to perform cleaning while propelling the main body within a preset cleaning area;    a dust temperature detecting section having a heat detection sensor provided adjacent to the suction mouth and determines whether or not a temperature of a sucked piece of the dust is higher than a predetermined temperature;    a water detecting section having a water detection sensor provided adjacent to the suction mouth, and determines whether or not water is sucked through the suction mouth;    a valve that is provided between the suction mouth and the first and second dust rooms;    a dust room switching section that controls the valve to collect a piece of dust whose temperature is determined higher than the predetermined temperature by the dust temperature detecting section into the first dust room, to collect a piece of dust whose temperature is determined not higher than the predetermined temperature by the dust temperature detecting section into the second dust room, to collect the water sucked through the suction mouth into the first dust room.    
   
   
       2 . A self-propelling cleaner comprising: 
 a main body provided with a first and a second dust rooms for accommodating dust;    a self-propelling section that propels the main body;    a sucking section provided with a suction mouth and a suction fan, and collects into one of the first and second dust rooms dust that is sucked through the suction mouth by rotating the suction fan;    a cleaning section that controls the self-propelling section and the sucking section to perform cleaning while propelling the main body within a preset cleaning area;    a dust temperature detecting section having a heat detection sensor provided adjacent to the suction mouth and determines whether or not a temperature of a sucked piece of the dust is higher than a predetermined temperature;    a valve that is provided between the suction mouth and the first and second dust rooms;    a dust room switching section that controls the valve to collect a piece of dust whose temperature is determined higher than the predetermined temperature by the dust temperature detecting section into the first dust room, and to collect a piece of dust whose temperature is determined not higher than the predetermined temperature by the dust temperature detecting section into the second dust room.    
   
   
       3 . The self-propelling cleaner according to  claim 2 , further comprising a water detecting section having a water detection sensor provided adjacent to the suction mouth, and determines whether or not water is sucked through the suction mouth, 
 wherein the dust room switching section controls the valve to collect the water sucked through the suction mouth into the first dust room.    
   
   
       4 . The self-propelling cleaner according to  claim 2 , wherein the first dust room includes a box made of an inflammable material for accommodating the dust.
