摘要： PURPOSE:To prevent the lowering of the quantity of air blown off at the time of changing the blow-off direction of the air by a method wherein guide walls opening widely toward the downstream side of blow-off port are provided and air guide plates are oscillated at the upstream side of the blow-off port. CONSTITUTION:Guide walls 11a and 11b which open widely outwardly from a nozzle section 12 are provided and air guide plates 6a and 6b which are rotatable through an operating lever are provided on the upstream side of the nozzle section 12. With the above structure, in case where it is desired to deflect a stream of air blown off from the nozzle section 12, the guide plate 6a is so positioned that it extends along the guide wall 11a. Consequently, a greater part of the air from a fluid supply port 15 is blown off from the nozzle section 12 without lowering its flow rate due to the existence of the guide plates 6a and 6b. Further, in case where it is desired to obtain a straight forward stream of air, the plates 6a and 6b are held parallel to the axis C.

摘要： PURPOSE:To adjust blow-off air quantity and improve cooling effect by moving at least a part of a nozzle wall forming a nozzle part as a movable plate and making variable the nozzle diameter. CONSTITUTION:The nozzle diameter of a nozzle part 4 is maximum when a movable plate 20 is in a state where it is tightly contacted to a side wall plate 3a, and the nozzle diameter becomes minimum when the movable plate 20 rectangularly intersects the side wall plate 3a. For example, in a case where at large quantity of blow-off air is desired at the time of rapid cooling or rapid heating, the inclination angle theta with respect to the side wall plate 3a of the movable plate 20 is set to zero and the nozzle diameter of the nozzle part 4 is made maximum. In the case of the nozzle diameter being maximum, the injected fluid is not deviated in correspondence to the operation of a wind direction guide plate 8. When the nozzle diameter becomes small, the ejected fluid is deviated by the operation of the plate 8.

CONSTITUTION:A fluid blow-off device causes cool air A from an air conditioner to blow either deflected left AL or deflected right AR by turning on or off a control coil 7 to cause a control passage to open or shut respectively. A circuit 18 to detect temperature difference which is to output temperature difference signals correscponding to a temperature difference on the basis of signals from a pair of thermo-sensitive devices 19, 20 is provided near air blow outlets of the subject blow-off device. In addition to this, a circuit to determine time period of fixed flow blowing 40 is provided which can function for outputting fixed flow signals as soon as the control switch 10 of the air conditioner is turned on and also for outputting oscillatory flow signals upon the temperature difference signal reaching preset level as set for optional preference. When the oscillatory flow signal is outputted, the control coil 7 is controlled through a switching circuit 17 on the basis of blow-off time ratio of output from a comparator circuit 14.

摘要： PURPOSE:To improve air cooling warming effect without giving discomfort by a method wherein when the temperature of a blown fluid reaches a preset temperature, an oscillation flow change command is generated to control a fluid blowing part so that an oscillation range is turned over between the upward and downward directions. CONSTITUTION:When an oscillation part 30 is constantly outputting a square wave 30a, if the resistance value of a thermister of a blown air temperature sensor 40 increases according to the blowing of a cool air, and if a voltage level becomes higher than the voltage level of a setting resistor 42, the oscillation flow change command is outputted through a comparator 43. This command signal is inputted into an AND circuit through an inverter 51 and also into another AND circuit 53 directly, and when the respective circuits 52 and 53 output ''1'', transistors 61 and 62 are turned ON. When the transistors 61 and 62 are ON, coils 72 and 73 are energized and an air direction change valve 71 is made to swing in the vertical direction through armatures 75 and 76. Thus, an oscillation air flow is generated.
