(3) action
Fig. 4 is the cutaway view of the indoor apparatus of air conditioner in running.In Fig. 4, the first suction inlet 21 and the second suction inlet 22 are in open mode.In addition, in the indoor apparatus of air conditioner of present embodiment, indoor fan 15 has adopted cross flow fan, and therefore, in air stream, from the second suction inlet 22, to blow-off outlet 19, mobile air stream is main flow, even only the first suction inlet 21 is opened, and also hardly can air amount.Therefore, when the first suction inlet 21 is opened, it is prerequisite that the second suction inlet 22 is opened.
(3-1) on-off action of the first suction inlet 21 based on opening-closing plate 311
As shown in Figure 4, at the first suction inlet 21, during in predetermined open position, an end of opening-closing plate 311 and the lower end of underframe 17 approach, and opening-closing plate 311 is taked form such on the elongated surfaces of the wall in underframe 17.Here, for convenience of explanation, the position of the opening-closing plate 311 shown in Fig. 1 is called to closed position, the open position of the opening-closing plate 311 shown in Fig. 4 is called to the A position.
The wall of underframe 17 be air the mediation that makes to send from indoor fan 15 (below, be called Air Conditioning) gradually to such curved surface of the place ahead, bottom deflection, so Air Conditioning is advanced until blow out from blow-off outlet 19 along the wall of underframe 17.
The blow-off direction of Air Conditioning that arrives blow-off outlet 19 is variable on above-below direction by baffle plate 291, particularly, below the vertical from blow-off outlet 19 until the variable range in horizontal the place ahead of blow-off outlet 19.But the Air Conditioning of in fact being controlled in the Air Conditioning of blow-off direction the concave side by baffle plate 291 is object, the Air Conditioning by convex side blows out along the curved surface of underframe 17.Therefore, in the situation that the air quantity of the Air Conditioning blown out is little and there is no the impetus, there is the possibility in the first suction inlet 21 that directly is inhaled into rear.
But, it is just more approaching that one end of opening-closing plate 311 and the lower end of underframe 17 do not form in fact gap, and take on the elongated surfaces of opening-closing plate 311 in the wall of underframe 17 such or on the face parallel with this elongated surfaces such form, therefore, even, in the situation that the air quantity of the Air Conditioning blown out is little and there is no the impetus, Air Conditioning is also advanced to the place ahead, bottom along opening-closing plate 311.
As mentioned above, opening-closing plate 311 in the A position on one side the direction to the Air Conditioning that blows out from blow-off outlet 19 controlled, directly be inhaled into the phenomenon (so-called short circuit) in the first suction inlet 21 Yi Bian suppress this Air Conditioning.
(3-2) regulation of the first suction inlet 21 based on opening-closing plate 311
The open position of opening-closing plate 311 is not limited to A position (open position shown in Fig. 4), and the such open position limited in the soakage to coming from the first suction inlet 21 also can be static.
Fig. 5 is the side view of the opening-closing plate periphery that stops at each open position.In Fig. 5, opening-closing plate 311 can stop to the optional position the A position from closed position.For convenience of explanation, to have rotated the open position of 60 ° be ，She Cong closed position, B position that to have rotated the open position of 30 ° to clockwise direction be the C position from closed position to clockwise direction to establish opening-closing plate 311.With at B position ratio, the air sucked from the first suction inlet 21 when the C position is more restricted.
(3-2-1) regulation of the first suction inlet 21 during cooling operation
In the past, in indoor apparatus of air conditioner, when cooling operation, from blow-off outlet along level or slightly oblique upper by air adjustment and Air blowing, and from being positioned at the air intake by the air-conditioning object space than the suction inlet of the position of the top section of blow-off outlet, therefore, air easily occurring in the air-conditioning object space stagnates.
On the other hand, prevent desirable air stream that air is stagnated be from blow-off outlet 19 along level or the Air Conditioning that slightly oblique upper blows out along ceiling, wall, floor, the wall convection current of air-conditioning object space the such air-flow be inhaled into from the first suction inlet 21 (below, be called inviscid flow), up to the present, still worry short circuit and be not achieved.
But, when cooling operation, when the temperature T r of design temperature Ts and air-conditioning object space poor (Ts-Tr) reaches predetermined value when above, it is large that the air quantity of blow out air becomes, the impetus of the Air Conditioning blown out from blow-off outlet 19 surpasses the inhalation power of the first suction inlet 21, thereby is not easy to be short-circuited.Therefore, at Ts-Tr, reach predetermined value when above, opening-closing plate 311 is moved to B position or C position, when regulating the aperture of the first suction inlet 21, can realize the inviscid flow of Air Conditioning.
In addition, in the indoor apparatus of air conditioner of present embodiment, in the difference of the temperature T r of design temperature Ts and air-conditioning object space during lower than predetermined value, blow out air down and air quantity also little, easily be short-circuited, therefore, opening-closing plate 311 is in the closed position, and the first suction inlet 21 is closed.
(3-2-2) regulation of the first suction inlet 21 while heating running
Usually, heating when running, heated Air Conditioning being blown out downwards, is floor along the air-conditioning object space, wall, ceiling convection current such flowing of being inhaled into from the suction inlet of front upper part.In the present embodiment, because the second suction inlet 22 is equivalent to the suction inlet of front upper part in the past, therefore, can realize flowing of Air Conditioning in the past under the state that the first suction inlet 21 is closed.
In addition, when Air Conditioning blows out downwards, the first suction inlet 21 is opened and can be caused short circuit, therefore, preferably maintain the state that the first suction inlet 21 is closed.
But, when wanting to improve heating capacity, in the situation that only depend on the second suction inlet 22 can't obtain the air amount of q.s, needs are regulated the aperture of the first suction inlet 21 and are increased the air amount amount.
Now, when the temperature T r of design temperature Ts and air-conditioning object space poor (Ts-Tr) reaches predetermined value when above, it is large that the air quantity of blow out air becomes, and the impetus of the Air Conditioning blown out from blow-off outlet 19 surpasses the inhalation power from the first suction inlet 21, thereby is not easy to be short-circuited.
Therefore, at Ts-Tr, reach predetermined value when above, opening-closing plate 311 is moved to B position or C position and the aperture of regulating the first suction inlet 21, can improve heating capacity.
(3-2-3) with the regulation that blows out corresponding the first suction inlet 21 of angle
In addition, control part 41 can be according to the aperture that blows out angle and regulate the first suction inlet 21.For example, because the first suction inlet 21 is positioned at the rear of blow-off outlet 19, therefore, also can so that the Air Conditioning blown out from blow-off outlet 19 blow out the more approaching lower limit downwards of angle, the position of opening-closing plate 311 just more approaches the mode of closed position, and rotary opening closing plate 311 dwindles the aperture of the first suction inlet 21.
Carve at a time, blowing out of the Air Conditioning blown out from blow-off outlet 19 is that level blows out, the position of opening-closing plate 311 is in the situation of the B position Fig. 5, along with baffle plate 291 approaches the vertical below, control part 41 moves between C position or C position and closed position the position of opening-closing plate 311.
(3-2-4) with the regulation of corresponding the first suction inlet 21 of ability
In addition, control part 41 can be regulated the aperture of the first suction inlet 21 according to the ability that requires to indoor apparatus of air conditioner.Usually, when the Air Conditioning blown out from blow-off outlet 19 has the impetus, Air Conditioning is not easy to be inhaled in the first suction inlet 21.It is air quantity when large that the Air Conditioning blown out has the impetus, and normally the air-conditioning load of air-conditioning object space is large and while needing ability.Therefore, preferably according to required ability, regulate the aperture of the first suction inlet 21.
For example, when heating running, when the user has improved design temperature, the corresponding ability of ascending amount to the indoor apparatus of air conditioner requirement with design temperature, when the operating frequency of the frequency-changeable compressor of outdoor pusher side (not shown) etc. rises, the rotation of indoor fan 15 is also risen, and the amount of air amount also increases.Now, in the situation that only depend on the quantity not sufficient from the air amount of the second suction inlet 22, regulate the aperture of the first suction inlet 21 and supplement not enough air amount.
Because the amount of supplementing air amount is larger, the air quantity of the Air Conditioning blown out from blow-off outlet 19 is also larger and the impetus is arranged, and therefore, even increase the aperture of the first suction inlet 21, also is not easy to cause short circuit.
In other words, the amount of supplementing air amount is less, and the air quantity of the Air Conditioning blown out from blow-off outlet 19 is also less and there is no the impetus, but, because the aperture of the first suction inlet 21 also diminishes, the impetus therefore sucked also diminishes, and is not easy to cause short circuit.
As mentioned above, by adopting the method for regulating the aperture of the first suction inlet 21 according to required ability, thereby the amount of spin that for example control part 41 is controlled opening-closing plate 311 according to the rotating speed of indoor fan 15 gets final product, the angle from controlling, easily carry out regulation.
(3-2-5) with the regulation that corresponding the first suction inlet 21 of condition is set
And control part 41 has the aperture selected cell, described aperture selected cell is limited the slewing area of opening-closing plate 311, with the regulation range constraint by the first suction inlet 21 in particular range.For example, exist with the first suction inlet 21 below approaching curtain rail and can't physically open and close the time, while perhaps not wanting to suck the air from the window side of curtain, by selecting in advance the pattern opened and closed and storing, thereby can limit the aperture of the first suction inlet 21.
In addition, in fact, because opening-closing plate 311 is limited to move to the A position in Fig. 5, therefore become uncontrollable in (3-2-1) the direction of such Air Conditioning blown out from blow-off outlet 19 of explanation.Therefore, control part 41 is controlled the action of opening-closing plate 311 according to the scope of selecting by the aperture selected cell on one side, on one side the action of baffle plate 291 is controlled to avoid short circuit.Particularly, can avoid the such attitude that makes the Air Conditioning blowing down of baffle plate 291.
(3-3) regulation of the second suction inlet 22 based on slide opening and closing plate 322
In the indoor apparatus of air conditioner of present embodiment, the air stream that flows to blow-off outlet 19 from the second suction inlet 22 in air stream is main flow, when the first suction inlet 21 is opened, it is prerequisite that the second suction inlet 22 is opened, but allows the second suction inlet 22 is carried out to regulation (but except closed condition).
For example, at opening-closing plate 311 in the A position and also do not cause the short circuit of Air Conditioning but under desirable air-flow and stable such state, when wanting to limit the amount of air amount, with comparing of the aperture that opening-closing plate 311 is rotated dwindle the first suction inlet 21, the aperture that the slide opening and closing plate 322 that makes the second suction inlet 22 moves to dwindle the second suction inlet 22 to closing direction more can not upset the stable state of Air Flow, can limit the amount of air amount.
In addition, during indoor apparatus of air conditioner 2 shuts down, for the second suction inlet 22 is stayed open, the ratio end face that slide opening and closing plate 322 is incorporated in main body cover 11 is the position of side on the lower, this be because, because the second suction inlet 22 can be piled up dust with the opposed part of ceiling surface when stopping, therefore, in the situation that hypothesis slide opening and closing plate 322 is closed, the dust that is deposited in its upper surface when slide opening and closing plate 322 is opened likely can be rubbed lower and be entered into main body cover 11 inboards, is in order to prevent such situation.Even by also slide opening and closing plate 322 being opened when running stops, thereby dust is deposited on filter, and therefore can suppress dust enters into main body cover 11 inside.
In addition, the ratio end face that is incorporated in main body cover 11 due to slide opening and closing plate 322 during the second suction inlet 22 is opened is side on the lower, therefore, the state exposed with end face from main body cover 11 is compared, dust is not easy to pile up, and the vibration that can also suppress owing to moving to closing direction makes dust fall such situation to floor side.
(4) feature
（4-1）
In indoor apparatus of air conditioner 2, due to want directly to the first suction inlet 21 (A position) the passage of mobile air to have opening-closing plate 311 from blow-off outlet 19, therefore, utilize opening-closing plate 311 to make the direction deflection of air flow away from the first suction inlet 21.Consequently, can suppress the generation of short circuit.
（4-2）
The A position of opening-closing plate 311 is that the lower end of the end of opening-closing plate 311 and underframe 17 approaches and do not form in fact the position in gap between the lower end of blow-off outlet 19 and underframe 17.The path that the most easily sucks Air Conditioning from the path of blow-off outlet 19 to first suction inlets 21 is the mobile path of mode of stroking the lower end of underframe 17, therefore, by avoid and the lower end of this underframe 17 between form gap, thereby can suppress Air Conditioning, be inhaled in the first suction inlet 21.
（4-3）
In indoor apparatus of air conditioner 2, when the first suction inlet 21 is opened, the angle that blows out of the Air Conditioning blown out from blow-off outlet 19 is adjusted to Air Conditioning is blown out to the direction away from the first suction inlet 21, therefore can suppress short circuit.
(5) variation
(5-1) the first variation
Fig. 6 is the cutaway view of the indoor apparatus of air conditioner of the first variation.The actuating mechanism of the baffle plate 291 in blow-off outlet switching mechanism 29 is different from the embodiment described above.In Fig. 6, in the first variation, be not equivalent to the parts of the fulcrum 292 in above-mentioned embodiment, the ground that replaces, utilize bar 295 to release to the open position position on the front of the baffle plate 291 than in above-mentioned embodiment.Therefore, form gap between the lower end of the edge of baffle plate 291 and underframe 17.
But opening-closing plate 311 is by moving to A position (with reference to Fig. 5), thereby the lower end of an end and underframe 17 approaches, and the edge of the other end and baffle plate 291 approaches.Consequently, during blowing out from blow-off outlet 19 in Air Conditioning, the gap formed between the lower end of the edge of baffle plate 291 and underframe 17 is stopped up by opening-closing plate 311 in fact, and the Air Conditioning that therefore can suppress to blow out is inhaled in the first suction inlet 21.
In addition, in the indoor apparatus of air conditioner of the first variation, because baffle plate 291 and opening-closing plate 311 arranged in series become a large baffle plate, work, so the blow-off direction of Air Conditioning is stable.
(5-2) the second variation
Fig. 7 is the cutaway view of the indoor apparatus of air conditioner of the second variation.The actuating mechanism of the opening-closing plate 311 in the first suction inlet switching mechanism 31 is different from the embodiment described above.In Fig. 7, in the second variation, be not equivalent to the hinge 312 of above-mentioned embodiment and the parts of connecting rod 313, opening-closing plate 311 slides mobile along guide rail 315.The mobile principle of sliding is identical with the slip shifting principle of the slide opening and closing plate 322 of the second suction inlet 22, be pre-formed rack pinion at opening-closing plate 311, by utilizing stepper motor or being built-in with the stepper motor driving of reduction gear and the pinion that this rack pinion meshes, mobile thereby opening-closing plate 311 slides.
In addition, in the indoor apparatus of air conditioner of the second variation, for example, even there be the curtain rail approaching with the below of the first suction inlet 21, also can avoid physically opening and closing such situation.Therefore, without above-mentioned embodiment, such aperture selected cell that passes through selects the pattern of the switching of opening-closing plate 311 also to store.
(5-3) the 3rd variation
Fig. 8 A is the cutaway view of the first suction inlet periphery of closing of the indoor apparatus of air conditioner of the 3rd variation.In addition, Fig. 8 B is the cutaway view of the first suction inlet periphery of opening of the indoor apparatus of air conditioner of the 3rd variation.In Fig. 8 A, at the first suction inlet 21, be provided with the first suction inlet switching mechanism 31.The CD-ROM drive motor (not shown) that the first suction inlet switching mechanism 31 comprises the opening-closing plate 311 of rotary type and this opening-closing plate 311 is rotated.
The size of opening-closing plate 311 is the sizes that are embedded in the opening of the first suction inlet 21 and can stop up the first suction inlet 21.The turning cylinder 317 of opening-closing plate 311 is positioned at the top at the length direction both ends of the first suction inlet 21.Opening-closing plate 311 is bonded by articulated section 319 with turning cylinder 317.
In addition, the closed position of the first suction inlet 21 being closed at opening-closing plate 311, turning cylinder 317 is positioned at the top of opening-closing plate 311 and is positioned at the position by blow-off outlet 19 than the central authorities of the width of opening-closing plate 311.Therefore, rotate 90 ° by turning cylinder 317 to the CW direction in Fig. 8 A, thereby opening-closing plate 311 becomes the approaching vertical attitude in the edge, the place ahead of its outer surface and the first suction inlet 21.
Consequently, as shown in Figure 8 B, opening-closing plate 311 becomes the outstanding a little state in below from the first suction inlet 21 to vertical.Below half of the width size that preferably this outstanding size is opening-closing plate 311.This be because, in the situation that the installation site of indoor apparatus of air conditioner 2 is directly over curtain rail, if can interfere with curtain rail when the outstanding size of opening-closing plate 311 is long.
In addition, the air-flow flowed out due to the direction from blow-off outlet 19 to the first suction inlet 21 flow along the surface of shield 33 (with reference to the arrow A IR Fig. 8 B), therefore, even the outstanding size of opening-closing plate 311 also can fully be blocked this air-flow below half of width size.Therefore, can prevent short circuit.
