But, owing to being provided with first suction inlet 21 that can open and close, therefore, oblique upper from blow-off outlet along level or slightly by air adjustment and Air blowing the time, make the first suction inlet become open mode, therefore, until the place do not arrived by endless form air in the past all produces cross-ventilation, can suppress to occur air and stagnate.In addition, due to air along level or slightly oblique upper blow out, therefore can prevent short circuit (Air Conditioning blown out from blow-off outlet 19 directly is inhaled into the phenomenon the first suction inlet 21).
On the other hand, even in the situation that Air Conditioning from blow-off outlet 19 along level or slightly oblique upper blow out, while approaching due to the temperature T r of design temperature Ts and air-conditioning object space, air quantity diminishes, therefore the possibility that produces short circuit is high, likely cause in this case ability to reduce, therefore close the first suction inlet 21.
In addition, 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, therefore Air Conditioning is blown to the direction away from the first suction inlet 21, is not easy to be short-circuited.
Therefore, even when Air Conditioning blows out, at Ts-Tr, reach predetermined value when above downwards, 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 ideal flow of Air Conditioning.Like this, in the present embodiment, can capable of preventing short circuit, and can suppress to occur air and stagnate.
In addition, at blow out air downwards and the difference of the temperature T r of design temperature Ts and air-conditioning object space during lower than predetermined value, air quantity is little, easily is short-circuited, and therefore, opening-closing plate 311 is in the closed position, and the first suction inlet 21 is closed.Therefore, can avoid short circuit.
(3-1-2) regulation of the first suction inlet 21 while heating running
Usually, heating when running, heated Air Conditioning is to blow out downwards and at the convection current of air-conditioning object space and such air-flow 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, for fear of short circuit, 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.
(3-1-3) 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 angle is regulated the first suction inlet 21 that blows out of blow out air.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.
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.
(3-1-4) 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.The Air Conditioning blown out has the impetus to refer to when air quantity is large, 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.
(3-1-5) 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, control part 41 can be 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 also controlled to avoid short circuit.Particularly, can avoid the such attitude that makes the Air Conditioning blowing down of baffle plate 291.
(3-2) 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-flow 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 preferably also 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 stream and stable such state, when wanting to limit the amount of air amount, with the aperture that makes opening-closing plate 311 rotations dwindle the first suction inlet 21, compare, 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, suppose in the situation that 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 the position of 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, owing to being provided with the first suction inlet 21, therefore, oblique upper from blow-off outlet 19 along level or slightly by air adjustment and Air blowing the time, make the first suction inlet 21 become open mode, therefore, until the place do not arrived by endless form air in the past all produces cross-ventilation, can suppress to occur air and stagnate.In addition, due to air along level or slightly oblique upper blow out, therefore can prevent short circuit.
In addition, even during the air from blow-off outlet 19 blow out air mediation downwards, when large and air quantity blow out air of poor (Ts-Tr) of the temperature T r of design temperature Ts and air-conditioning object space is large, be not easy to be short-circuited, therefore making the first suction inlet 21 is open mode.
On the other hand, at Ts-Tr hour, the air quantity of blow out air is also little, therefore easily is short-circuited, but, because the first suction inlet 21 is closed, therefore can be short-circuited.
（4-2）
In indoor apparatus of air conditioner 2, because indoor fan 16 is that cross flow fan and main flow are the air-flow towards blow-off outlet 19 from the second suction inlet 22, therefore, by the aperture of regulating the second suction inlet 22, produce suitable main flow, thus can be from the first suction inlet 21 air amounts.
（4-3）
In indoor apparatus of air conditioner 2, the aperture that angle is regulated the first suction inlet 21 that blows out according to the air blown out from blow-off outlet 19, prevent short circuit.
（4-4）
In indoor apparatus of air conditioner 2, due to the regulation that can carry out first suction inlet 21 corresponding with the increase and decrease of required air imbibed quantity, therefore, when the high ability that need to accompany with the increase of air imbibed quantity, the first suction inlet 21 can be opened and tackled.
（4-5）
In indoor apparatus of air conditioner 2, the first suction inlet 21 is adjacent with the rear of blow-off outlet 19, air to blow out angle variable on above-below direction.Blowing out angle below vertical the time, the first suction inlet 21 is closed, therefore can capable of preventing short circuit.
（4-6）
In indoor apparatus of air conditioner 2, in the time opening-closing plate 311 physically can't being opened and closed or while not wanting to suck the air from the window side of curtain, by the aperture selected cell, select the pattern opened and closed also to store in advance, thereby can limit the aperture of the first suction inlet 21.
(5) variation
(5-1) the first variation
Fig. 6 A is the cutaway view of the first suction inlet periphery of closing of the indoor apparatus of air conditioner of the first variation.In addition, Fig. 6 B is the cutaway view of the first suction inlet periphery of opening of the indoor apparatus of air conditioner of the first variation.In Fig. 6 A, at the first suction inlet 21, be provided with the first suction inlet switching mechanism 31.The CD-ROM drive motor 318 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 can be embedded in the opening of the first suction inlet 21 and 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 and turning cylinder 317 are bonded by articulated section 319.
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, by turning cylinder 317, to the CW direction in Fig. 6 A, rotate 90 °, thereby opening-closing plate 311 becomes the approaching vertical attitude in edge, the place ahead (edge of a side of close blow-off outlet 19) of its outer surface and the first suction inlet 21.
Consequently, as shown in Figure 6B, 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 this case, because the outstanding size of opening-closing plate 311 is short, the air-flow blocking-up of therefore direction from blow-off outlet 19 to the first suction inlet 21 being flowed out is insufficient, has the possibility be short-circuited.Therefore, in the situation that blow-off direction is downward, by carrying out the control that the first suction inlet 21 is closed, thereby prevent that short circuit is in possible trouble.
(5-2) the second variation
Fig. 7 A is the cutaway view of the first suction inlet periphery of closing of the indoor apparatus of air conditioner of the second variation.In addition, Fig. 7 B is the cutaway view of the first suction inlet periphery of opening of the indoor apparatus of air conditioner of the second variation.In Fig. 7 A, at the first suction inlet 21, be provided with the first suction inlet switching mechanism 31.The first suction inlet switching mechanism 31 comprises opening-closing plate 411, hinge 412, connecting rod 413 and CD-ROM drive motor 414.
The size of opening-closing plate 411 is the sizes that can be embedded in the first suction inlet 21 and stop up the first suction inlet 21.Opening-closing plate 411 can rotate, near the edge of the edge that the imaginary central axis of its rotation is arranged in the first suction inlet 21 side away from far from blow-off outlet 19.
Hinge 412 is fulcrums that opening-closing plate 411 rotates, and it is arranged on the wall of the main body cover 11 intersected with the imaginary central axis of rotating.Hinge 412 is bonded by connecting rod 413 with opening-closing plate 411.
CD-ROM drive motor 414 is stepper motor or the stepper motor that is built-in with reduction gear, and its rotating shaft and hinge 412 link.Take the state of opening-closing plate 411 in being accommodated in the first suction inlet 21 during as origin position, and CD-ROM drive motor 414 makes the rotating shaft rotation according to the umber of pulse be applied in, and opening-closing plate 411 is to the direction rotation that the first suction inlet 21 is opened.Now, the end that opening-closing plate 411 becomes a side of the close blow-off outlet 19 in self end drops to the attitude of the below of the first suction inlet 21.
In this case, the air-flow that the direction from blow-off outlet 19 to the first suction inlet 21 flows out flows along the surface of shield 33, and is inhaled in the first suction inlet 21.Therefore, in Air Conditioning from blow-off outlet 19 along level or during the common cooling operation that slightly oblique upper blows out, the first suction inlet 21 is opened to suppress to occur air to be stagnated, but for example, at air quantity hour (when the temperature T r of design temperature Ts and air-conditioning object space approaches), easily be short-circuited, so opening-closing plate 311 closes to prevent short circuit by the first suction inlet 21.
On the other hand, when heating running, heated Air Conditioning blows out downwards, owing to opening the first suction inlet 21, can cause short circuit, therefore, for fear of this situation, maintains the state that the first suction inlet 21 is closed.But, 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 of the first suction inlet 21, thereby is not easy to be short-circuited.Therefore, at Ts-Tr, reach predetermined value when above, the first suction inlet 21 is opened, can improve heating capacity.
(6) other embodiment
In addition, also the load in nearest room (air-conditioning object space) diminishes sometimes, heating after when running, room warmed up in a way, it is also conceivable that and made the angle that blows out of the air that blows out from blow-off outlet 19 upwards make the running of the air circulation in whole room.
Therefore, for example, in the situation that heat when running design temperature Ts and poor (Ts-Tr) of the temperature T r of air-conditioning object space be less than predetermined value, what also can be made the air that blows out from blow-off outlet 19 blows out angle for level or the control of upwards the first suction inlet 21 being opened than level.
Thus, air is along the ceiling of air-conditioning object space, wall, floor, wall and therefore convection current being inhaled into from the first suction inlet 21, can make the air circulation in whole room when heating running.
Utilizability on industry
As mentioned above, according to the present invention, even make the rear of suction inlet and blow-off outlet adjacent, also can suppress blow out air and directly be inhaled into, be therefore useful to wall-hanging air conditioner indoor unit.
