Abstract: PURPOSE: To keep a room air clean by providing an electric heater on a cleaning filter and making the cleaning filter work during heating at time of burning and during low-capacity heating based on electric heating.  
     CONSTITUTION: An exhaust pipe 5 connected to a burner 4 is installed inside a body casing 1 equipped with an outlet 2 and an inlet 3 and a cleaning filter 6 is arranged inside an exhaust pipe 5. The cleaning filter 6 has numerous small apertures and has an electric heater buried inside. A switchover valve 10 is provided inside an air duct 9 communicating the upstream side with the down-stream side of the cleaning filter 6, so that an outlet for a blower 11 is put in communication. When an electric heater 8 alone is used, the switchover valve 10 is arranged at a position shown in the figure so as to blow an air to the upstream of the cleaning filter 6. During the operation of the burner 4, an air is blown to the downstream of the cleaning filter 6 by means of the switch-over valve 10 to mix with a cleaned combustion gas.

Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To accurately detect a theft action into a vehicle, etc., and to prevent misalarming by deciding whether a 2nd threshold value larger than a 1st threshold is reached in a control part, and deciding a theft action when the 2nd threshold is reached and generating an alarm by an alarm part. SOLUTION: A pulse timer circuit 30, comparators 26-1 to 26-n, AND circuits 32-1 to 32-n, etc., in the control part 14 detect what level an output wave from a sensor 10 rises to reach in 60 nm after exceeding a threshold. A decision circuit 34 receives the result and decides which of a disturbance element and an artificial theft action caused the output wave to rise. The output wave caused by the artificial theft action reaches the threshold in 60 ms, so the decision circuit 34 decides the theft action and outputs an alarm signal to an alarm sound synthesizing circuit 18-1. On receiving it, the alarm part 16 outputs an alarm sound from a speaker 20.
