One motor M is to link one to hold piece C on main shaft, is to be sheathed in the stacker 41 of baffle plate 40, does synchronous swing start to drive baffle plate 40;
One motor fixing base 30 is after the storing that a motor M is provided and fixing, and with screw these holder 30 nails is tied in bottom nozzle 22 its breach 223 lower edges;
One baffle plate 40, be for a circular plate body be installed in 22 of base 21 and bottom nozzles with the control airduct go out (or row) air quantity, convex with a stacker 41 and one and stacker 41 corresponding fulcrums 42 on its lateral margin respectively, and form an axial line L;
One controller 50, it is the lateral margin that is installed in bottom nozzle 22, also can receive in the appropriate location of other next-door neighbour's airducts 20, and the inside of this controller 50 is provided with a CPU, and the body of this controller 50 has outwards been received one or more sensing element, a control element and a setting member certainly.See also shown in Figure 4; setting value and sensing element 71 that controller is imported setting member 60; 72 detecting value; via the alternate analysis 55 in the controller 50; comfort adjusts 56; after the comparison such as shutdown demand 57 computing circuits such as grade; treated again unit 54 outputs one corresponding control signal; this control signal is sent to turning control cell 51; rotary speed controling unit 52 and start time control unit 53; governing factor as decision motor M; can read for the user to show correlation values by processing unit 54 another signals of output to digital display 90 in addition simultaneously, wherein:
This setting member 60 is to be the demand of user to temperature or humidity, carbon monoxide etc. in the environment, the executive component of the correlation that sets:
One or more sensing element 71,72 or the like is the detecting value in order to the temperature in the detecting environment, humidity, carbon dioxide etc.;
This function control component 80 is for being set at manual operation or automatically operation, and the function control component of selecting cold air, heating installation running mode;
Combination by said elements, when controller 50 its sensors be according to conditioned area in to the air-supply or the demand of air draft, the project of its required sensing is surveyed in choosing, the target that is selected survey is as being temperature, and then this sensor 71 is a temperature detector, and the target of surveying as choosing is an air quantity, it then is an air quantity sensor, that is to say according to the difference of the target requirement of measuring, select the sensor of different sensing projects to measure its required sensing value, and use the environment temperature that reaches in its conditioned area of correct detecting or air quantity or the like.
See also shown in Figure 5, be to be function block schematic diagram of the present invention, and the flow chart of the present invention of contrast Fig. 6, when sensing element 71,72 sensing value VA that detected and setting member 60 set definite value VS via controller 50 comparison operations after, three control signals are provided, be sent to turning control cell 51 respectively and promptly determine the direction of just changeing or reversing, rotary speed controling unit 52 promptly determines the velocity of rotation of motor and the time that start time control unit 53 promptly determines revolution, and three kinds of control module transmission of control signals thus respectively again, be turning to of decision motor M, the time of rotating speed and rotation, swing angle with control air door baffle plate 40, and it is the value of constantly and at any time detecting in the environment because of sensing element, so its each detecting value constantly is neither necessarily identical, controller 50 has different control signals, therefore can have different three control signals (to turn at any time, rotating speed and start time) three factors that decide motor M to rotate.
Because this motor is a gear motor, after the rate conversion via inner deceleration device, only be controlled at last and do the running start between 0-90 °, and this motor M, then link on its main shaft and hold piece C, because of holding piece C, this is sheathed in the stacker 41 of baffle plate 40, so that its amount of spin holds piece C with directly synchronous interlock and drives stacker 41 during the motor spindle running, and make baffle plate 40 at fully open position to doing the swing start between the complete shut-down position (as Fig. 7, shown in 8), also because the swing start of this baffle plate 40 in airduct, make and send (or row) air quantity to be controlled between standard-sized sheet and complete shut-down, variation according to indoor its environment value, so that controller 50 is according to the result of CPU computing, with the amount of spin of control motor M main shaft, and drive the size of baffle plate 40 its swing angles of regulation and control, and make and send (or row) air quantity to become a kind of variable air quantity supply of modulation at random with the control air quantity, guaranteeing that environmental demand in the conditioned area maintains in the scope of setting, and reach the saving of the energy and improve service efficiency.
Seeing also shown in Figure 9ly, is to multiply by the graph of a relation of the duration of runs for baffle opening and the positive rotating speed of motor, as seen from the figure the aperture of (baffle plate is by closing to the direction of opening) and positive rotating speed+S when baffle plate just changes
NMultiply by the T duration of runs
NValue be directly proportional, rotating speed is meant the unit interval amount of spin (i.e. the angle of Zhuan Donging) of motor drive shaft, and is X in the motor shaft turn amount
HThe time, baffle opening is 100%, and this baffle plate is at fully open position, so baffle opening is bigger, and the air quantity that passes through is bigger.Seeing also shown in Figure 10ly, is to be that baffle opening and motor reverse speed-S
NMultiply by the T duration of runs
NGraph of a relation, when baffle plate (being about to baffle plate by opening to the direction of closing) when reversing, the aperture of its baffle plate is inversely proportional to reversing the product of speed with the duration of runs as seen from the figure, if the aperture of baffle plate is littler, the air quantity that passes through is littler.So learn that by above-mentioned air door baffle plate swing angle (motor shaft turn amount) and motor rotary speed multiply by the value relation between the two of the duration of runs and be directly proportional, motor rotary speed is directly proportional with the motor input power in addition, therefore can control the swing angle of damper plate by motor input power and input power time, if and its motor rotary speed is faster, promptly the air door baffle plate is just shorter to the time of full cut-off (or by full cut-off to standard-sized sheet) by standard-sized sheet; Otherwise if its motor rotary speed is slower, then the air door baffle plate is just longer to the time of full cut-off (or by full cut-off to standard-sized sheet) by standard-sized sheet, as shown in figure 11.
Moreover sensing element of the present invention is a difference that can be on demand and different sensing elements is arranged, and can adopt the sensing element of temperature-sensitive sticker, humidity sensor, carbon monoxide or carbon dioxide, to adapt to various environmental demand.
In addition, the plate shape of the baffle plate 40 in its airduct of the present invention can be according to the difference of the cross sectional shape of airduct, and becomes a corresponding plate shape with airduct, is square person as this airduct cross sectional shape, and then the plate shape of baffle plate 40 also is a square plate body thereupon.
