(3) action
Fig. 4 is the sectional view of the indoor apparatus of air conditioner in running.In the diagram, 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 have employed cross flow fan, and therefore, the air stream flowed from the second suction inlet 22 to blow-off outlet 19 in air stream is main flow, even if only opened by the first suction inlet 21, also sucks air hardly.Therefore, when the first suction inlet 21 is opened, it is prerequisite that the second suction inlet 22 is opened.
(3-1) based on the on-off action of the first suction inlet 21 of opening-closing plate 311
As shown in Figure 4, when the first suction inlet 21 is in predetermined open position, one end of opening-closing plate 311 and the lower end of underframe 17 close, opening-closing plate 311 is taked to be in form such in the elongated surfaces of the wall of underframe 17.Here, for convenience of explanation, the position of the opening-closing plate 311 shown in Fig. 1 is called closed position, the open position of the opening-closing plate 311 shown in Fig. 4 is called A position.
The wall of underframe 17 is such curved surfaces of air (hereinafter, referred to as Air Conditioning) after the mediation that fan 15 is indoor sent lower portion front deflection gradually, and therefore Air Conditioning is advanced until blow out from blow-off outlet 19 along the wall of underframe 17.
The blow-off direction arriving the Air Conditioning of blow-off outlet 19 is variable in the vertical direction by baffle plate 291, specifically, until the variable range in the horizontal front of blow-off outlet 19 below the vertical from blow-off outlet 19.But, being in fact objects by controlling in the Air Conditioning of blow-off direction by the Air Conditioning of the concave side of baffle plate 291, being blown out along the curved surface of underframe 17 by the Air Conditioning of convex side.Therefore, little and when there is no the impetus, there is the possibility be directly inhaled in first suction inlet 21 at rear at the air quantity of Air Conditioning of blowout.
But, it is more close that one end of opening-closing plate 311 and the lower end of underframe 17 do not form in fact gap, and it is such or be in form such on the face parallel with this elongated surfaces in the elongated surfaces taking opening-closing plate 311 to be in the wall of underframe 17, therefore, even if when the air quantity of Air Conditioning of blowout is little and when not having the impetus, Air Conditioning is also advanced along opening-closing plate 311 lower portion front.
As mentioned above, opening-closing plate 311 controls the direction of the Air Conditioning blown out from blow-off outlet 19 in A position, while suppress this Air Conditioning to be directly inhaled into phenomenon (so-called short circuit) in the first suction inlet 21.
(3-2) aperture based on the first suction inlet 21 of opening-closing plate 311 regulates
The open position of opening-closing plate 311 is not limited to A position (open position shown in Fig. 4), also can be static in the such open position limited the soakage coming from the first suction inlet 21.
Fig. 5 is the side view of the opening-closing plate periphery stopped in each open position.In Figure 5, opening-closing plate 311 can stop in the optional position from closed position to A position.For convenience of explanation, if opening-closing plate 311 have rotated 60 ° clockwise open position from closed position is B position, if the open position that have rotated 30 ° from closed position is clockwise C position.With at B position ratio, when C position from first suction inlet 21 suck air more restricted.
(3-2-1) aperture of the first suction inlet 21 during cooling operation regulates
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 after Air blowing, and from being positioned at the suction inlet of position in portion more top than blow-off outlet by the air intake of air-conditioning object space, therefore, in air-conditioning object space, easily there is air to stagnate.
On the other hand, the desirable air stream preventing air to stagnate be Air Conditioning from blow-off outlet 19 along level or slightly oblique upper blowout along the ceiling of air-conditioning object space, wall, floor, wall convection current the such air-flow be inhaled into from the first suction inlet 21 (below, be called inviscid flow), up to the present, still to worry short circuit and not being achieved.
But, when cooling operation, when the difference (Ts-Tr) of the temperature Tr of design temperature Ts and air-conditioning object space reaches more than predetermined value, the air quantity of blow out air becomes large, the impetus of Air Conditioning blown out from blow-off outlet 19, more than the inhalation power of the first suction inlet 21, thus short circuit is less likely to occur.Therefore, when Ts-Tr reaches more than predetermined value, opening-closing plate 311 is moved to B position or C position, while regulating the aperture of the first suction inlet 21, the inviscid flow of Air Conditioning can be realized.
In addition, in the indoor apparatus of air conditioner of present embodiment, when the difference of the temperature Tr of design temperature Ts and air-conditioning object space is lower than predetermined value, blow out air down and air quantity is also little, is easily short-circuited, therefore, opening-closing plate 311 is in the closed position, and the first suction inlet 21 is closed.
(3-2-2) aperture of the first suction inlet 21 when heating running regulates
Usually, when heating running, blow out by the Air Conditioning heated downwards, be along the floor of air-conditioning object space, wall, ceiling convection current the such flowing be 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, the flowing of Air Conditioning in the past can be realized under the state of being closed by the first suction inlet 21.
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 of being closed by the first suction inlet 21.
But, when wanting to improve heating capacity, when only the suction air of q.s cannot be obtained by the second suction inlet 22, needing the aperture of adjustment first suction inlet 21 and increasing suction air capacity.
Now, when the difference (Ts-Tr) of the temperature Tr of design temperature Ts and air-conditioning object space reaches more than predetermined value, the air quantity of blow out air becomes large, exceedes the inhalation power from the first suction inlet 21, thus short circuit is less likely to occur from the impetus of the Air Conditioning of blow-off outlet 19 blowout.
Therefore, when Ts-Tr reaches more than predetermined value, opening-closing plate 311 moved to B position or C position and regulate the aperture of the first suction inlet 21, can heating capacity be improved.
(3-2-3) aperture of the first corresponding to blowout angle suction inlet 21 regulates
In addition, control part 41 can regulate the aperture of the first suction inlet 21 according to blowout angle.Such as, because the first suction inlet 21 is positioned at the rear of blow-off outlet 19, therefore, also can to make the more close most lower limit downwards of the blowout angle of the Air Conditioning blown out from blow-off outlet 19, the position of opening-closing plate 311 is more close to the mode of closed position, and rotary opening closing plate 311 reduces the aperture of the first suction inlet 21.
In certain moment, when the blowout of Air Conditioning blown out from blow-off outlet 19 is level blowout, the position of opening-closing plate 311 is the B positions Fig. 5, along with baffle plate 291 is close to below vertical, control part 41 makes the position of opening-closing plate 311 move to C position or between C position and closed position.
(3-2-4) aperture of the first corresponding to ability suction inlet 21 regulates
In addition, control part 41 can according to the aperture requirement ability of indoor apparatus of air conditioner being regulated to the first suction inlet 21.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 of blowout have the impetus be air quantity large time, and normally the air conditioner load of air-conditioning object space is large and when needing ability.Therefore, the aperture of the first suction inlet 21 is preferably regulated according to required ability.
Such as, when heating running, when user improves design temperature, the ability corresponding to the ascending amount of design temperature is required to indoor apparatus of air conditioner, while the operating frequency rising of the frequency-changeable compressor (not shown) of outdoor pusher side etc., the rotation of indoor fan 15 is also risen, and the amount sucking air also increases.Now, when only leaning on the quantity not sufficient from the suction air of the second suction inlet 22, the aperture of the first suction inlet 21 is regulated to supplement not enough suction air.
Because the amount of supplementary suction air is larger, the air quantity of Air Conditioning blown out from blow-off outlet 19 is also larger and have the impetus, therefore, even if the aperture of increase the first suction inlet 21, is also not easy to cause short circuit.
In other words, supplement that to suck the amount of air less, the air quantity of the Air Conditioning blown out from blow-off outlet 19 is also less and do not have the impetus, but also diminishes due to the aperture of the first suction inlet 21, and the impetus therefore sucked also diminishes, and is not easy to cause short circuit.
As mentioned above, by adopting the method for the aperture regulating the first suction inlet 21 according to required ability, thus such as control part 41 controls the amount of spin of opening-closing plate 311 according to the rotating speed of indoor fan 15, from the angle controlled, easily carry out aperture adjustment.
(3-2-5) aperture of the first corresponding to setting model suction inlet 21 regulates
Further, control part 41 has aperture selection unit, and the slewing area of described aperture selection unit to opening-closing plate 311 limits, the aperture adjustable range of the first suction inlet 21 to be constrained in particular range.Such as, exist the curtain rail close with the below of the first suction inlet 21 and cannot physically opening and closing time, or when not wanting to suck the air from the window side of curtain, by selecting the pattern of opening and closing in advance and storing, thus the aperture of the first suction inlet 21 can be limited.
, because opening-closing plate 311 be limited to A position in Fig. 5 move, therefore become the direction of the uncontrollable such Air Conditioning from blow-off outlet 19 blowout that in (3-2-1) item illustrate in addition, in fact.Therefore, control part 41 is controlled, while carry out control to avoid short circuit to the action of baffle plate 291 according to the action of scope to opening-closing plate 311 selected by aperture selection unit.Specifically, the such attitude making Air Conditioning blowing down of baffle plate 291 can be avoided.
(3-3) aperture based on the second suction inlet 22 of slide opening and closing plate 322 regulates
In the indoor apparatus of air conditioner of present embodiment, the air stream flowing 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 second suction inlet 22 is opened, but allows to carry out aperture adjustment (but except closed condition) to the second suction inlet 22.
Such as, be in A position at opening-closing plate 311 and also do not cause the short circuit of Air Conditioning but desirable air-flow and under stable such state, when wanting to limit the amount sucking air, compared with making opening-closing plate 311 rotate to reduce the aperture of the first suction inlet 21, make the slide opening and closing plate 322 of the second suction inlet 22 move to closing direction the stable state that the aperture reducing the second suction inlet 22 more can not upset air flowing, the amount sucking air can be limited.
In addition, shut down period at indoor apparatus of air conditioner 2, stay open to make the second suction inlet 22, slide opening and closing plate 322 is incorporated in the ratio end face position on the lower of main body cover 11, this is because, the part opposed with ceiling surface due to the second suction inlet 22 can pile up dust when stopping, therefore, when supposing that slide opening and closing plate 322 is closed, the dust being deposited in its upper surface when slide opening and closing plate 322 is opened likely can be rubbed lower and be entered into inside main body cover 11, is to prevent such situation.Even if by also being opened by slide opening and closing plate 322 when operating and stopping, thus dust is piled up on the filter, therefore, it is possible to it is inner to suppress dust to enter into main body cover 11.
In addition, because during being opened by the second suction inlet 22, slide opening and closing plate 322 is incorporated in the ratio end face of main body cover 11 on the lower, therefore, compared with the state exposed with the end face from main body cover 11, dust is not easy to pile up, and can also suppress due to vibration when moving to closing direction and make dust fall such situation to floor side.
