The specific embodiment
Followingly one embodiment of the present of invention are described with reference to accompanying drawing.Fig. 1 is the indoor set of expression one embodiment of the present of invention and the figure of installment state thereof.
Ceiling type indoor machine 2 is installed on the ceiling 1 with the state of imbedding.Following (decoration panel) 2a of indoor set 2 is towards the interior space, and central portion of 2a forms air entry 3 below it, and the circumference of 2a forms 4 inflatable mouths 4 below.
Position corresponding with air entry 3 in indoor set 2 is provided with indoor fan 5, with the state that surrounds this indoor fan 5 indoor heat converter 6 is set.Form ventilation runner 9 respectively from this indoor heat converter 6 to above-mentioned each blowing mouth 4, in each ventilation runner 9 respectively swing freely (rotate naturally) to be provided with wind direction adjusting plate be so-called shutter board 7.These shutter board 7 mutual interlocks are arranged on same turned position mutually.And, between air entry 3 and indoor fan 5, be provided with indoor temperature transmitter 8.
In case indoor fan 5 actions, the air of the interior space sucks in the indoor set 2 by air entry 3.This inhaled air carries out heat exchange and becomes cold air or heating installation at indoor heat converter 6 places, and this cold air or heating installation blow out to the interior space from each blowing mouth 4.
The direction freedom that each shutter board 7 has the wind that will blow out from each blowing mouth 4 be set in changeably near horizontal (also claiming horizontal direction) A of ceiling 1 under either party function in the scope of E.In addition, shutter board 7 is that so-called shutter board waves by waving (repetition reciprocally swinging), the direction with the wind that will blow out from each blowing mouth 4 horizontal A under the function of waving in the scope of E.
And for horizontal A, confirm by experiment: when the blowing amount is big, shown in the dotted line of Fig. 2, and ceiling 1 between produce the whirlpool of air-flow, because of the influence of this eddy current, blowing is to ceiling 1 lateral deviation stream, blowing is flowed along ceiling 1, produces black spot phenomenon.
On the other hand, Fig. 3 represents the control loop of air conditioner of the present invention.
The refrigerant outlet of compressor 11 is connected with outdoor heat converter 13 by cross valve 12, and above-mentioned indoor heat converter 6 is connected with this outdoor heat converter 13 by electric expansion valve 14.Then, the refrigerant inlet of compressor 11 is connected with indoor heat converter 6 by above-mentioned cross valve 12.Constitute the Hot pump formula kind of refrigeration cycle that to freeze and to warm oneself thus.
Near outdoor heat converter 13, be provided with outdoor fan 15.These compressors 11, cross valve 12, outdoor heat converter 13, electric expansion valve 14, outdoor fan 15 etc. constitute off-premises station 10.
During refrigeration, the cold-producing medium of discharging from compressor 11 flows towards illustrated solid arrow direction, and outdoor heat converter 13 plays the function of condenser, and indoor heat converter 6 plays the function of evaporimeter.During heating, by switching cross valve 12, mobile towards the direction of illustrated dotted arrow from the cold-producing medium that compressor 11 is discharged, indoor heat converter 6 plays the function of condenser, and outdoor heat converter 13 plays the function of evaporimeter.
Control part 20 these air conditioner integral body of control.2 drive motors 7M, indoor temperature transmitter 8, frequency converter 21, distance type operator 30 that this control part 20 is connected with the drive motors 5M of cross valve 12, electric expansion valve 4, outdoor fan 15, respectively 2 shutter boards 7 is driven.
Frequency converter 21 carries out rectification with the voltage of commercial ac power source 22, the dc voltage conversion after this rectification is become the alternating voltage of the corresponding frequency of the instruction of sending with control part 20 and exports.This this output becomes the driving electric power of compressor 11.
Operator 30 has display part 31, operation/stop button 32, temperature and sets button 33, air quantity and set button 34, shutter board position adjustments button 35, shutter board and wave and set button 36 etc.By the operation of air quantity setting button 34, can be that the air quantity of the blowing of each blowing mouth 4 is set at a plurality of patterns such as " weak wind ", " apoplexy ", " high wind ", " air quantity automatically " with the air quantity of indoor fan 5.By operation, can regulate the turned position of each shutter board 7 to shutter board position adjustments button 35.By shutter board being waved the operation of setting button 36, can the shutter board of each shutter board 7 be waved (swing of the direction of blowing) and set and remove.
Control part 20 is the device with the major function of following (1) (2).
(1) when the direction of the wind that blows out from each blowing mouth 4 during near ceiling 1, no matter air quantity is set the setting of button 34, the air quantity that each blowing mouth 4 is blown out is limited in the control device that is lower than pre-determined setting value.
(2) shutter board waves when setting, hunting range to each shutter board 7 limits, so that do not become horizontal A near ceiling 1 from the direction of each blowing mouth 4 blowings, and the hunting range of each shutter board 7 increased along with the air quantity of indoor fan 5 and towards under the control device that dwindles to the E side.
Below, the effect to said structure describes with reference to flow chart shown in Figure 4.
When not setting shutter board and shaking ("No" of step 101), each shutter board 7 turns to and the operation of shutter board position adjustments button 35 and the corresponding angle of operational mode (refrigeration mode heating pattern dehumidification mode air supply pattern etc.), and the direction of the wind that blows out from each blowing mouth 4 can be set arbitrarily in A～E scope.
Between A～E which side blowing direction be set in to judging (step 102,103,104).When be judged as blowing direction near the occasion ("Yes" of step 102) of the horizontal A of ceiling 1, the rotating speed of target Fm and the setting value fa of indoor fan 5 compared (step 105).Rotating speed of target Fm sets the operation of button 34, the detected temperatures of setting indoor temperature transmitter 8 and the difference of desired temperature according to air quantity to set.
Greater than setting value fa ("Yes" of step 105), then rotating speed of target Fm is limited in setting value fa (step 106) as rotating speed of target Fm.When rotating speed of target Fm, does not then limit rotating speed of target Fm when following ("Yes" of step 105) at setting value fa, the rotating speed of target Fm of this moment remain stationary (step 107).
When blowing direction is judged as than horizontal A slightly to the occasion ("Yes" of step 103) of the tiltedly down direction B of downside, then rotating speed of target Fm and setting value fb are compared (step 108).Greater than setting value fb ("Yes" of step 108), then rotating speed of target Fm is limited in setting value fb (step 109) as rotating speed of target Fm.When rotating speed of target Fm less than setting value fb ("Yes" of step 108), then rotating speed of target Fm is not limited the rotating speed of target Fm remain stationary (step 107) of this moment.
When blowing direction is judged as than oblique below B more to the occasion ("Yes" of step 104) of the tiltedly down direction C of downside, then rotating speed of target Fm and setting value fc are compared (step 110).Greater than setting value fc ("Yes" of step 110), then rotating speed of target Fm is limited in setting value fc (step 110) as rotating speed of target Fm.When rotating speed of target Fm less than setting value fc ("Yes" of step 110), then rotating speed of target Fm is not limited the rotating speed of target Fm remain stationary (step 107) of this moment.
When blowing direction be judged as than oblique below C more to the tiltedly down direction D of downside or under the occasion ("No" of step 104) of E, then rotating speed of target Fm is not limited the rotating speed of target Fm of this moment remain stationary (step 107).
The driving of indoor fan 5 is controlled so that the rotating speed F of indoor fan 5 becomes rotating speed of target Fm (step 112) then.
The relation that has fa＜fb≤fc among setting value fa, fb, the fc.The direction of blowing is more near ceiling 1, and the upper limit of rotating speed of target Fm is set lowly more.
Like this, the direction of blowing has nothing to do with the operation of air quantity setting button 34 and the detected temperatures of indoor temperature transmitter 8 near the occasion of ceiling 1, be limited in below the pre-determined setting value by air quantity, then do not need structure or shape are improved the black spot phenomenon shown in the dotted line that just can prevent Fig. 2 reliably blowing.
Blowing direction is set in horizontal A mostly during refrigeration, during heating blowing direction have be set under to the trend of E.Therefore, can satisfy the black spot phenomenon when preventing to freeze and the comfortable heating of positive canyon simultaneously.
On the other hand, wave in case wave setting button 36 setting shutter boards by the operation shutter board, then each shutter board 7 repeats to shake (reciprocally swinging), and the wind that blows out from each blowing mouth 4 flows in the interior space while shaking at above-below direction.
When this shutter board waves ("Yes" of step 101), with the rotating speed of target Fm and setting value fb, the fc comparison (step 113,114) of outdoor fan 5.According to this comparative result, the swing range of each shutter board 7 is restricted.
Such as, when the occasion ("Yes" of step 113) of rotating speed of target Fm below setting value fb, the swing range of each shutter board 7 is limited between the direction B-E (step 115).When the occasion ("Yes" of step 114) of rotating speed of target Fm below setting value fc, the swing range of each shutter board 7 is limited between the narrow a little C-E of scope (step 116).When the occasion ("No" of step 114) of rotating speed of target Fm greater than setting value fc, the swing range of each shutter board 7 is limited between the narrowest direction D-E (step 116).
Especially, removed from the swing range of each shutter board 7 near the horizontal A of ceiling 1 and irrelevant with rotating speed of target Fm.Prevent black spot phenomenon by this reliably except that deenergizing.
And rotating speed of target Fm is big more, and swing range dwindles to the E side under the court more, and this point also can prevent black spot phenomenon reliably.
But, the present invention is not limited to the various embodiments described above, can carry out various distortion in the scope that does not change aim.
