Technical field

The present invention relates to a kind of indoor air conditioner is regulated and passed out to the air that is taken into inside.Particularly relate to the air conditioner that to send air upward.

Background technology

Existing air conditioner is to send air to approximate horizontal and even below.Therefore, if continue to blow under near the state indoor temperature arrives design temperature then cold wind or warm braw will blow to the user always.Thereby there is the problem of the user being brought unplessantness displeasure.In addition, when dehumidifying operation or refrigeration operation, there is user's body temperature part decline and health produced the problem of harm.

Therefore, open the spy and to disclose a kind of air conditioner in the 2003-232531 communique, can send the adjusting air, send air in the time of near indoor temperature arrives design temperature upward to level and even below.Fig. 9 sends the sectional view of indoor set one example of the air conditioner of air upward for expression.

The body that is configured near the indoor set 1 of indoor ceiling R is kept by the cavity 2 that is installed on the wall.Loading and unloading are equipped with front panel 3 freely in cavity 2.End face one side on the plate 3 and front one side are provided with suction inlet 4a, 4c in front.

Be formed with the blow-off outlet 5 of indoor set 1 in front in the gap between the bottom of the bottom of plate 3 and chamber 2 to the essentially rectangular of width extension.Be formed with the air-supply path 6 that is communicated to blow-off outlet 5 from suction inlet 4a, 4c in the inside of indoor set 1.In air-supply path 6, dispose fan 7.Driving by fan 7 will flow air be sent from blow-off outlet 5 in air-supply path 6.

Air-supply path 6 has upper wall 6a that tilts more upward towards the place ahead more and the lower wall 6b that tilts towards the place ahead more more downwards near blow-off outlet 5.Therefore, form along with blowing out 5 and enlarge gradually near the downstream.So, the kinetic energy of flow air is converted into static pressure in air-supply path 6.Thereby can alleviate the load of fan 7, increase air quantity.

Be provided with pneumatic filter 8 with front panel 3 position in opposite directions.The dust that is comprised is collected and removed to pneumatic filter 8 from suction inlet 4a, 4c inhaled air.In air-supply path 6, dispose indoor heat converter 9 between fan 7 and the pneumatic filter 8.

Indoor heat converter 9 is connected on the compressor of being located at outside the room (not shown).Driving by compressor moves freeze cycle.By the operation of freeze cycle, indoor heat converter 9 is cooled to below the low temperature of environment temperature during refrigeration.And indoor heat converter 9 is heated to above the high temperature of environment temperature when pyrogenicity.What be provided with in the bottom of indoor heat converter 9 front and back that refrigeration or when dehumidifying collect the dew that falls from indoor heat converter 9 holds dew dish 10.

At blow-off outlet 5 in the face of externally being provided with the horizontal shutter board 11a, the 11b that blow out angle that can change vertical direction.Laterally shutter board 11a opens and closes the top of blow-off outlet 5.Laterally shutter board 11b opens and closes the bottom of blow-off outlet 5.Can the transport direction of air be altered to below and even top by horizontal shutter board 11a, 11b.And, be provided with the vertical shutter board 12 that blows out angle that can change left and right directions in the inboard of horizontal shutter board 11a, 11b.

In the air conditioner of above-mentioned formation, when beginning the operation of air conditioner, fan 7 is driven in rotation.Refrigerant from off-premises station (not shown) flows to indoor heat converter 9, the freeze cycle operation.By the driving of fan 7, air is inhaled in the indoor set 1 from suction inlet 4a, 4c.Being included in this airborne dust is removed by pneumatic filter 8.

Being taken into air in the indoor set 1 and indoor heat converter 9 carries out heat exchange and is cooled or heats.And, regulate air by air-supply path 6 by vertical shutter board 12 limit its left and right directions towards, horizontal shutter board 11a, 11b by configuration down send downwards shown in arrow A 1 from blow-off outlet 5.Thereby carry out indoor air conditioning.

And under the state after indoor temperature is stable, as shown in figure 10, laterally shutter board 11a, 11b dispose towards the top.So, shown in arrow A 2, regulate air and send upward.Therefore, cold wind or warm braw can not blow to the user all the time, have reduced unplessantness displeasure.And, can prevent that local body temperature from reducing.

On the other hand, open shown in the 2002-89868 communique etc. as the spy, the air conditioner that possesses the ion generating device that produces ion in indoor set 1 also is known.This air conditioner is sent ion and adjusting air together from blow-off outlet 5.Therefore, can obtain air cleaner effect and soft effects such as sterilization.

When adopting above-mentioned Fig. 9, existing air conditioner shown in Figure 10, transversely shutter board 11a, 11b be upward or the below guiding for the air of sending from blow-off outlet 5.As shown in Figure 9, the air after the adjusting does not flow along the upper wall 6a in air-supply path 6 when sending air downwards.Therefore, the air of room temperature is attracted to the air that the direction of arrow A 1 is sent and is flowed into shown in arrow B 2 in the air-supply path 6.

At this moment, leaked-in air is detained under the state of the upper wall 6a that touches air-supply path 6, is cooled to dew-point temperature by regulating air when refrigeration operation or dehumidifying operation.Therefore, exist the upper wall 6a in air-supply path 6 to go up the problem that produces dewfall 99.

Similarly, as shown in figure 10, the air after the adjusting is sent to the direction of arrow A 2 when sending air upward.Attracted by this air, the air of room temperature flows in the air-supply path 6 from the below shown in arrow B 1.Therefore, leaked-in air is detained under the state of the lower wall 6b that touches air-supply path 6, exists the lower wall 6b in air-supply path 6 to go up the problem that produces dewfall 99.Because the different air of temperature is in contact with it on the two sides of horizontal shutter board 11b, so also there is the problem that produces dewfall 99 on the wall of horizontal shutter board 11b.

And, because air-supply path 6 enlarges towards blow-off outlet 6,, the adjusting air flow to blow-off outlet 5 so enlarging radially.Therefore, when sending air downwards as shown in Figure 9, the horizontal shutter board 11a of the air on blow-off outlet 5 tops and top collides and pressure loss increase.

Similarly, when sending air upward as shown in figure 10, blow out the air of 5 bottoms and the horizontal shutter board 11b of below and collide and pressure loss increase.And flow air is left upper wall 6a or lower wall 6b because of collision in air-supply path 6.Therefore, flow area reduces, and the conversion efficiency that kinetic energy is converted to static pressure reduces.Therefore, the problem that has the air quantity minimizing of sending by fan 7.

In addition, in the air conditioner that ion and adjusting air are sent together, ion is because of losing electric charge with horizontal shutter board 11a or horizontal shutter board 11b collision.Therefore, exist ion to disappear or desactivation, the problem that reduces to the amount of indoor ion of emitting.

Action when Fig. 2 represents that the below of the air conditioner of above-mentioned formation blows out.When beginning the operation of air conditioner, fan 7 is driven in rotation.Refrigerant from off-premises station (not shown) flows to indoor heat converter 9, the operation freeze cycle.By the driving of fan 7, air sucks in the indoor set 1 from suction inlet 4a, 4c.The dust that contains in this air is removed by pneumatic filter 8.And ion generating device 30 is driven, and emits ion from discharge face 30a in air-supply path 6.

Being taken into air in the indoor set 1 and indoor heat converter 9 carries out heat exchange and is cooled or heats.And, regulate air by air-supply path 6 by vertical shutter board 12 limit its left and right directions towards.The horizontal shutter board 11b of below is configured in and the normal place of bottom flow air almost parallel in air-supply path 6.So, in the transversely extending direction guiding of shutter board 11b of bottom flow air in air-supply path 6.

The horizontal shutter board 11a of top is that the direction of the upper wall 6a in approaching more air-supply path 6 disposes obliquely towards the downstream more with respect to the air flow of top flow air in air-supply path 6.The air of substantial middle portion by air-supply path 6 is the many air stream of air capacity the and laterally angle of shutter board 11a is big.Therefore, the direction of the air stream when transversely shutter board 11b ground does not arrive blow-off outlet 5 is sent.So, the main flow of the most of air that flows in air-supply path 6 is sent to the direction that flows in the bottom flow air from substantial middle portion shown in arrow A 1.

And the air on the top by air-supply path 6 is by laterally shutter board 11a guiding, sends along the upper wall 6a in air-supply path 6.At this moment, owing to send to the direction of arrow A 1 from the primary air that blows out 5, the air capacity of flow air is few between upper wall 6a and horizontal shutter board 11a.Therefore, the air of sending is attracted by main flow (A1) according to wall attachment effect, is directed to main flow direction shown in arrow A 4.So, regulate air and send downwards together, can when carrying out indoor air conditioning, obtain air cleaner effect and soft effect in ion.

And under the indoor temperature stable status, as shown in Figure 3, the horizontal shutter board 11a of top is configured in and the normal place of top flow air almost parallel in air-supply path 6.So, the top flow air in air-supply path 6 guides on the extending direction of horizontal shutter board 11a.

The horizontal shutter board 11b of below is that the direction of the lower wall 6a in approaching more air-supply path 6 disposes obliquely towards the downstream more with respect to the air flow of bottom flow air in air-supply path 6.The air of substantial middle portion by air-supply path 6 is the many air stream of air capacity the and laterally angle of shutter board 11b is big.Therefore, the direction of the air stream when transversely shutter board 11b ground does not arrive blow-off outlet 5 is sent.So, the main flow of the most of air that flows in air-supply path 6 is sent to the direction that flows in the top flow air from substantial middle portion shown in arrow A 2.

And the air of the bottom by air-supply path 6 is by laterally shutter board 11b guiding, sends along the lower wall 6b in air-supply path 6.At this moment, owing to send to the direction of arrow A 2 from the primary air that blows out 5, the air capacity of flow air is few between lower wall 6b and horizontal shutter board 11b.Therefore, the air of sending is attracted by main flow (A2) according to wall attachment effect, is directed to main flow direction shown in arrow A 5.So, because cold wind or warm braw are not to blow to the user all the time, so can reduce unplessantness displeasure.And, can prevent that local body temperature from reducing.

If adopt present embodiment, then send when regulating air downwards, the horizontal shutter board 11a of top is with respect to the direction of the upper wall 6a in approaching more air-supply path 6 tilts towards the downstream more in the top in the air-supply path 6 flow air flow direction.Therefore, the air on air-supply 6 tops, path and upper wall 6 a flow contiguously.Its result, the air of room temperature does not flow into from blow-off outlet 5 along upper wall 6a shown in arrow B 2 (with reference to Fig. 2).Therefore, can prevent the dewfall of upper wall 6a.

Similarly, when sending the adjusting air upward, the horizontal shutter board 11b of below flows to the direction of the lower wall 6b in approaching more air-supply path 6 inclination towards the downstream more with respect to the bottom flow air in air-supply path 6.Therefore, the air of air-supply 6 bottoms, path and lower wall 6b flow contiguously.Its result, the air of room temperature does not flow into from blow-off outlet 5 along lower wall 6b shown in arrow B 1 (with reference to Fig. 3).Therefore, can prevent the dewfall of lower wall 6b.

And the air on air-supply 6 tops, path flows towards the top along the upper wall 6a in air-supply path 6 among Fig. 2.Therefore, the air that is blocked by the horizontal shutter board 11a of top is a spot of.Similarly, the air of air-supply 6 bottoms, path flows towards the below in air-supply path 6 among Fig. 3.Therefore, the air that is blocked by the horizontal shutter board 11b of below is a spot of.

So, can reduce air stream and the laterally collision of shutter board 11a, 11b.In addition, can also prevent to convert kinetic energy to static pressure effectively from the reducing of the flow area that blows out 5 air of sending.Therefore, the air quantity that can prevent air conditioner reduces.And, can prevent that ion from disappearing, and improves sterilization and soft effect.
