Work according to the blade control device of the ceiling board air conditioner device of the present invention of said structure is described now.
When the user utilizes mode of operation selector 44 input temperature desired, can select the heating mode or the refrigerating mode that adapt with temperature desired.Correspondingly, signal is selected in one of output.When air-conditioner according to user's temperature desired, when working under heating mode, microprocessor 45 compares current indoor temperature and the temperature of setting in advance, carries out heated at high speed work, and determines whether current indoor temperature is no more than the temperature of setting.If when current indoor temperature is higher than design temperature, carry out common heating work.When if current indoor temperature is lower than design temperature,,, can carry out heated at high speed work by increasing venting air velocity by exhaust openings 31a～31d for the cold indoor temperature that raises fast.Microprocessor 45 one of output are carried out the revolution control signal of heated at high speed pattern and are given vane drive parts 36 and 40.Vane drive parts 36 rotate blade 32a and the 32d that is connected with first motor 37 with 40, close exhaust openings 31a and 31d; And rotate blade 32b and the 32c that is connected with second motor 41, to open exhaust openings 31b and 31c.After the predetermined time of process, the revolution control signal of the operation of opening blade that microprocessor output control is opposite with the operation of closing blade is given vane drive parts 36 and 40, to carry out heated at high speed work.
Microprocessor 45 compares current indoor temperature and the predefined temperature of carrying out heated at high speed work.If current indoor temperature is higher than predefined temperature, does not then carry out heated at high speed work, and export a revolution control signal of carrying out common heating work.Carry out the user under the situation of common cooling work, the revolution control signal of common cooling work is carried out in output.That is to say that under the situation of common heating work or common cooling work, microprocessor 45 one of output are controlled the revolution control signal of blade rotation simultaneously and given motor 37 and 41.Therefore, vane drive parts 36 and 40 open and close exhaust openings 31a～31d simultaneously.
Yet, as when air-conditioner carries out common heating work or common cooling work, force and select the situation of heated at high speed pattern such, by the control blade, can carry out common heating work or common cooling work.For example, when the user feels very cold, and when wishing quick rising indoor temperature, the user can operate a special button of forcing mode of operation, with first and second motors of control by microprocessor control.Therefore, as under the situation of selecting the heated at high speed pattern, can under common heating pattern or common refrigerating mode, control blade.
To illustrate in greater detail the method for control blade below.
When the user utilizes mode of operation selector 44 to select heating mode, microprocessor 45 adds on first drive motors 37 electric energy, make when second and the 3rd exhaust openings 31b and 31c are in closed condition, can open first and the 4th exhaust openings 31a and 31d.When first drive motors 37 began to rotate, the rotatory force of first drive motors 37 passed to first connector 39 by travelling gear 38.When first connector 39 rotates, wholely correspondingly rotate with first and the 4th blade 32a that is connected rotationally and 32d with its.Therefore, first and the 4th exhaust openings 31a and 31d open.
Microprocessor 45 control fans 34 make that room air can suck by suction opening 33 when first and the 4th exhaust openings 31a and 31d open.When fan 34 rotates, be sucked into the air of housing 35 inside by suction opening 33, by indoor heat converter 30.When by indoor heat converter 30, air themperature raises.Heated air is discharged by first and the 4th exhaust openings 31a and 31d.Above-mentioned sequence of operations can repeat.Therefore, when carrying out heated at high speed work, by increasing discharging power, air-conditioner is expelled to the bottom with the air of heating, thereby can improve indoor temperature.
Microprocessor 45 is added on second drive motors 41 electric energy, make second and the 3rd exhaust openings 31b and 31c can air by first and the 4th exhaust openings 31a and 31d discharge the back that of one predetermined period of process open constantly.When second drive motors 41 started working, the rotatory force of second drive motors 41 passed to second connector 43 by travelling gear 42.When second connector 43 rotated, second and the 3rd exhaust openings 31b and 31c opened.Microprocessor is controlled first drive motors, makes that first and second exhaust openings are closed almost second and the 3rd moment that exhaust openings is opened.
The velocity of rotation of each blade from open position to the closed position is identical with the velocity of rotation of each blade from the closed position to open position.Microprocessor 45 is correspondingly controlled first drive motors 37 and second drive motors 41, makes that the rotational angle of the relative vertical direction of each blade is approximately 60 ° when corresponding blade is opened.
Fig. 5 is the flow chart of expression according to the method for controlling vanes of ceiling board air conditioner device of the present invention.
As shown in Figure 5, the method for controlling vanes of ceiling board air conditioner device comprises the following steps: to be selected by the user selection mode of operation step (S10) of refrigerating mode or heating mode; When selecting heating mode in step S10, more current indoor temperature and predefined temperature are to carry out heated at high speed work and to determine whether current indoor temperature is higher than the step (S20) of predefined temperature; Open two blade 32a being connected with motor 37 and exhaust openings 31a and the 31d of 32d, and close two blade 32b being connected with motor 41 and exhaust openings 31b and the 31c of 32c, with the control blade, carry out heated at high speed work, the venting air communication is crossed the step (S30) that the exhaust openings 31a that opens and 31d discharge; After carrying out heated at high speed work, determine whether current indoor temperature is not less than the step of the temperature that pre-determines setting (S40); With after carrying out heated at high speed work, cancel heated at high speed and carry out common heating work, at this moment corresponding blade 32a～32d opens or closes the step (S50) of exhaust openings 31a～31d simultaneously.
Comprise that also the control blade carries out the step of common cooling work.At this moment, when selecting refrigerating mode in step S10, respective vanes 32a～32d opens or closes exhaust openings 31a～31d simultaneously.In addition, also comprise the step (S60) that the control blade carries out common heating work.At this moment, when in step S20, when current indoor temperature was higher than predefined temperature, corresponding blade 32a～32d opened or closed exhaust openings 31a～31d simultaneously.
Fig. 6 represents the waveform that fan speed that the vane drive pattern with the ceiling board air conditioner device adapts changes.
As shown in Figure 6, microprocessor 45 control blades make that the time that respective vanes stops, than when each blade is opened corresponding exhaust openings, the time that respective vanes stops is long when closing corresponding exhaust openings.For example, each blade turns to time of open position and each blade and turns to time of closed position from open position from the closed position, be approximately 5 seconds respectively; And under the state that corresponding exhaust openings is opened, the time that each blade stops to be approximately 1 fen; Close at each blade under the state of corresponding exhaust openings, the time that each blade stops to be approximately 50 seconds.Like this, in the time that blade opens or closes, the venting air-flow can pass to indoor equably.
In addition, because first and the 4th operation that blade 32a, 32d carry out is opposite with the operation of second and the 3rd blade 32b and 32c, therefore the venting air velocity by slype increases.Correspondingly, the air stream of heating can arrive indoor bottom.Microprocessor 45 can reduce the velocity of rotation of fan 34, so that produce the venting air-flow in the one predetermined period when blade rotation or before blade rotation the time, thereby reduces noise.Therefore, two blades being connected with 43 with first and second connectors 39 open or close under the state of the 1st～4th the corresponding exhaust openings among exhaust openings 31a～31d, can reduce noise.
For example, can increase wind speed as follows: began before blade is opened time point t1, t3, t5 and the t7 of direction rotation at two blades, rotate with little rotating speed drive fan 34; With close fully at two blades before time point t2, the t4 and t6 of corresponding exhaust openings, increase the rotating speed of fan 34.Like this, can be at time point t2, t4 and the t6 place that exhaust openings is closed fully, with the rotating speed drive fan that increases.Therefore, the air stream of heating can arrive the bottom.
As mentioned above, according to the present invention, when two blade 32a that are connected with motor 37 and 32d closed exhaust openings 31a and 31d, two the blade 32b and the 32c that are connected with motor 41 rotated, and exhaust openings 31b and 31c are opened.Therefore, the speed of the venting air-flow by exhaust openings 31b and 31c increases.Like this, the venting air-flow can promptly arrive indoor bottom.When blade rotation, or pre-determine in the time at blade rotation a section before the time, the rotating speed that produces the fan 34 of venting air-flow reduces.Thereby noise reduces.When predetermined time past tense, can control the work that blade is closed exhaust openings, it is opposite to make itself and blade open the work of exhaust openings.Thereby, the temperature of the whole indoor bottom that can raise equably.
