摘要： PURPOSE:To improve reliability by preventing erroneous stop from being generated again by re-registering the learnt result when the erroneous stop occurs after learning is completed. CONSTITUTION:A flow rate signal G from a flow rate measuring means 1 is calculated into a real flow rate P1 by a flow rate arithmetic part 2. During a prescribed learning term, a learning processing part 3 calculates a flow rate pattern Q as the learnt result and holds it. Further, a flow rate decision part 4 receives the flow rate pattern Q from the learning processing part and a flow rate pattern P2 from the flow rate arithmetic part and compares them and in the case of abnormality, a stop/alarm signal R is outputted. A stop alarming means 5 issues an alarm or stops a gas route. While receiving the signal of this flow rate decision part 4, a stop flow rate storage part 6 stores a flow rate pattern F at the time of stop. Corresponding to an input from the outside, a reregister signal T is outputted by an erroneous stop time reregister signal input means 7. An erroneous stop time reregister processing part 8 instructs the holding of the flow rate pattern F in the stop flow rate storage part 6 to the learning processing part 3 and updates the learnt result.

摘要： PURPOSE:To improve reliability and safety by deciding stop corresponding to the use pattern of a gas equipment and the simultaneous start of individual equipments. CONSTITUTION:An individual equipment estimating means 2 estimates the individual equipment by the increase/decrease of a flow rate and outputs an estimated individual arithmetic flow rate. While a timer 3 is operated by an individual flow rate registration starting means 4, an individual flow rate storage means 5 registers this estimated individual arithmetic flow rate. After the timer 3 is stopped, an abnormality decision part 6 outputs an individual abnormal signal to an alarming means or stopping means 7 when the estimated individual arithmetic flow rate is not contained in the individual flow rate stored in the individual flow rate storage means 4.

摘要： PURPOSE:To prevent exhaustion of a battery for power supply of a gas shutting- off device by reducing the number of times for repeating shutting-off action. CONSTITUTION:A flow amount calculating unit 2 calculates an actual flow amount P upon receiving a flow amount signal G from a flow amount measuring means 1. A flow amount judging unit 4 makes its judgment by comparing a shutting-off value D held by a data holding unit 3 with the actual flow amount P from the flow amount calculating unit 2 and outputs a shutting-off/warning signal R. A shutting-off/warning means 5 issues a warning information and shuts off a gas passage based on the shutting-off/warning signal R. An answer signal detecting means 6 outputs an answer signal A when it detects nonshutting- off even during a shutting-off sequence. A count processing unit 7 allows output of the shutting-off signal until counter number of the answer signal A reaches its specified number.

摘要： PURPOSE:To improve the safety and reliability of the device by changing a stop deciding method corresponding to the condition of actually using an individual equipment. CONSTITUTION:The flow rate of the individual equipment to be used is previously stored in an individual flow rate storage equipment to be means 4. An individual equipment estimating means 2 estimates the individual equipment from the increase/decrease of the flow rate outputs an estimated individual arithmetic flow rate. When this estimated individual arithmetic flow rate is not contained in the individual flow rate stored in the individual flow rate storage means 4, an abnormal flow rate decision part 5 outputs an individual abnormal signal to an alarming means or stopping means 6. Corresponding to the time of the estimated individual arithmetic flow rate or the reset of an alarm, a normal individual flow rate registering means 7 stores this estimated individual flow rate in the individual flow rate storage means 4.

摘要： PURPOSE:To prevent generation of discomfort sound and a variation in a pumping amount by a simple structure by standing a cylindrical metal gauze concentrically with a funnel from a bottom of a water pan at inside or/and outside of an end of the funnel. CONSTITUTION:A condenser body 1 having a top late 1a and a cylindrical skirt 1b is arranged above a water pan 2. a cylindrical stainless steel gauze 7 is so stood to protrude at its upper end from a horizontal surface as to surround a lower part of a funnel 4 at a center of the pan 2. The funnel 4 is mounted at a shaft of a fan motor 11 and rotatably driven together with a fan 5. Accordingly, water in the pan 2 tends to form a vortex flow due to recessing at a center by a centrifugal force, but the gauze 7 becomes a resistance for the vortex flow to suppress generation of the vortex flow, thereby preventing generation of noise due to the vortex flow and further suppressing a variation in a water level near the center of the pan 2 by the vortex flow, and hence a variation in a pumping amount can be prevented.

摘要： PURPOSE:To shorten impressing time of a monitoring voltage for an oxygen sensor during combustion and prevent the deterioration of the oxygen sensor by a method wherein the monitoring voltage of the oxygen sensor is impressed only when an oxygen concentration detecting information is required for correcting the output of a fan by a correcting means. CONSTITUTION:A correcting unit 12d corrects the output of a fan 4 only when it is decided that operation is in the optimum condition by a deciding unit 12e while a monitoring voltage control unit 12g impresses the monitoring voltage of an oxygen sensor 16 only when an oxygen concentration detecting information is requested in order to correct the output of a fan 4 by the correcting unit 12d. In this case, the monitoring voltage control unit 12g impresses the monitoring voltage of the oxygen sensor 16 only when it is decided by the deciding unit 12e that operation is in the optimum condition and when it is decided that the operation is not in the optimum condition, the impression of the monitoring voltage is stopped. According to this method, the impressing time of the monitoring voltage of the oxygen sensor 16 during combustion can be shortened and the deterioration of the oxygen sensor 16 can be prevented.
