These critical pieces that constitute integrated air conditioner 1 are contained on the base 5, and constituent components 2, assembly 2 are installed in the outer container 4, deckboard 3 is housed in front forms integrated air conditioner 1.
As explained above, the dividing plate 6 of the central part of integrated air conditioner 1 by being arranged on base 5 is an outdoor side 7 and an indoor side 8 with the internal separation of integrated air conditioner 1, in an indoor side 8, dispose indoor heat converter 16, below indoor heat converter 16, be provided with dew container 21.And at the rear portion of indoor heat converter 16, the blower fan that is configured in an outdoor side 7 is projected in the indoor side 8 by dividing plate 6 with the rotating shaft of motor 17, and its end is equipped with indoor fan 19.Between indoor heat converter 16 and indoor fan 19, be provided with mouthful circle 27, indoor fan 19 rotations and the room air that sucks are sucked by indoor fan 19 by this mouthful circle 27.
On the other hand, at an outdoor side 7 places,, outdoor fan 18 is installed at its leading section giving prominence in the inside of chamber 25 with the rotating shaft of the set outdoor side of the opposite side of an indoor sidespin rotating shaft of motor 17 with the blower fan of front.And, drive outdoor fan 18 by driving blower fan with motor 17, upper air suction inlet 12 by outer container 4 and side air suction inlet 13 are drawn into the inside of integrated air conditioner 1 with outdoor air, and compressor 14 and the blower fan that is configured in an outdoor side 7 places cooled off with motor 17.So, be drawn in the chamber 25 with the outdoor air of motor 17 mouth circle 26 by fan house 24 with having cooled off compressor 14 and blower fan.In this outdoor air, the condensed water sputtering that accumulates in outdoor fan 18 bottoms is split into to vaporific, the outdoor air that will contain vaporific condensed water is blown into outdoor heat converter 15 and makes outdoor heat converter 15 coolings.Therefore on the surface of outdoor heat converter 15 condensed water is carried out evaporation process.
By connection be positioned at deckboard 3 the bottom, have the power switch of the electric component 11 of operating portion, integrated air conditioner 1 entry into service, the drive manner of integrated air conditioner 1 is by changing the formation of freeze cycle configuration of components and combination etc., can constitute air-cooling system running or heater unit running and other drive manner, and in the explanation of present embodiment, be that the running to air-cooling system is illustrated.
By connecting power switch, the gas shape cold-producing medium of the HTHP that is produced by compressor 14 is sent in the outdoor heat converter 15, the cold-producing medium of inlet chamber outer heat-exchanger 15 is cooled off by the outdoor air that outdoor fan 18 blows, and the highly pressurised liquid shape cold-producing medium that becomes temperature decline is sent out from outdoor heat converter 15.The cold-producing medium of sending outdoor heat converter 15 is lowered by decompressor (not shown) pressure, enters indoor heat converter 16 as the liquid refrigerant of low pressure.Enter the low pressure liquid shape cold-producing medium of indoor heat converter 16, from evaporating by capturing heat the room air that indoor heat converter 16 sucks excessively by indoor fan 19, be changed to the low low-pressure gas shape cold-producing medium of temperature and be inhaled in the compressor 14, be collapsed into the gas shape cold-producing medium of high temperature, high pressure by compressor 14, carry out the freeze cycle of integrated air conditioner 1 once more.
On the other hand, the room air that sucks by indoor fan 19, by indoor heat converter 16 time, cooled dose seizes heat and when being cooled, make the hydrogenesis that contains in the air and dehumidified, become dry cold air and be discharged to indoor from room air outlet 10.Through repeatedly such, indoor environment is adjusted to the comfortable state of suitable life.
Also have, the condensed water that is condensed by indoor heat converter 16 is collected in the dew container 21 that is arranged at indoor heat converter 16 bottoms, import in the water guide path 22, by dividing plate 6, accumulate in the storage part 23 that is arranged at outdoor fan 18 bottoms, by being arranged on splashing ring 18c on the outdoor fan 18 the condensed water processing of dispersing.
Be documented in the integrated air conditioner in the patent documentation 2, its outdoor fan uses screw ventilation, be illustrated according to Figure 10, as also illustrating in front, use at outdoor fan under the situation of screw ventilation, the problem that exists is: lift up impact sound that the blade of the water droplet of condensed water and screw ventilation bumps and impact sound that the water droplet of the dispersion of being upspring by the screw ventilation blade bumps against on the fin of outdoor heat converter all increases.In addition, the problem that exists is: owing to be merely able to be provided with along the periphery of screw ventilation blade the guide ring of the air-flow of adjusting screw ventilation, so, it is big that the diameter of guide ring becomes, by blade upspring and the water droplet that splashes from the fly out outside of fan house of guiding ring portion, the water droplet that is produced is dispersed to outdoor by the outdoor air suction inlet of integrated air conditioner always.
In addition, the problem of existence also has: be arranged on the ring that splashes on the screw ventilation that lifts up condensed water, owing to apart from the screw ventilation blade certain distance is arranged, when its diameter increases, weakened then, so, can not guarantee fully and the screw ventilation blade between spacing.Therefore, in case being arranged on the amount of condensed water of the storage part of outdoor heat converter bottom increases, also have following problem: ring not only splashes, even the blade of screw ventilation, the capital touches the water surface of condensed water, when will produce the sound of blade beating condensed water, the condensed water that is splash by blade disperses to the outside of integrated air conditioner from air suction inlet.
On the other hand, outdoor fan adopts multiblade fan in patent documentation 1, passes through outdoor heat converter suction chamber outer air from outdoor heat exchange one side.And, make condensed water sputtering in the outdoor air that sucks in the cover with the ring that splashes of leafy chip blower fan, and be discharged to outdoor from the outdoor air outlet that is arranged on outdoor heat converter next door with original state.Because leafy chip blower fan is that mouth circle by cover sucks by the outdoor air that outdoor heat converter sucked, the condensed moisture that the ring that splashes disperses is dispersed on the outdoor heat converter, can not carry out evaporation process to it.
So, there are the following problems: the condensed water in outdoor air of dispersing is owing to be present in the air with the original state of fine liquid particles, thereby make condensed water be drops and discharge outdoor the wetting of outdoor air outlet that make on every side, simultaneously, tiny water droplet flocks together, and water droplet drips from integrated air conditioner.In addition, though have by the air that will fully contain moisture blow in the outdoor heat converter, with the method for the heat exchanger effectiveness that improves outdoor heat converter, but under the situation of patent documentation 1, owing to have the outdoor air that sucks by outdoor heat converter at first, thereby can not effectively utilize the outdoor air that makes condensed water sputtering and fully contain moisture.In addition, by will in air, becoming on the outdoor heat converter that vaporific condensed water is blown into high temperature, though can make vaporific condensate evaporation, but, in the patent documentation 1, owing to be not to be blown into outdoor heat converter, but discharge from the outdoor air outlet, so the variety of issue that condensed water causes because of the water droplet that has original state with original state.
In an embodiment, outdoor fan adopts centrifugal fan, the outdoor air that will contain condensed water is blown on the outdoor heat converter, when making the heat exchanger effectiveness raising of outdoor heat converter, also makes it not have condensed water to drop onto the outside from the air outlet of integrated air conditioner.
Centrifugal blower such as Fig. 5 or shown in Figure 13, fix along the circumferential part of the wheel hub plate with the hub portion of fixing centrifugal blower on rotating shaft making separately an end of the blade of shape, the other end of blade is fixed on the guard shield of the annular shape plectane that forms air suction inlet.So the rotation by centrifugal blower sucks air from the rotating shaft direction of centrifugal blower, make air draught deflection centrifugal direction by wheel hub plate, air is discharged from the centrifugal direction of blade.In order to be induced to the air that centrifugal direction is discharged on certain direction, generally adopt a cover.
In patent documentation 1, the general centrifugal blower that adopts the wing that leans forward that is called as multiblade fan in patent documentation 3, adopts the centrifugal blower of the hypsokinesis wing that is called as turbofan.
But, such as previously described centrifugal blower being used under the situation of outdoor fan, be drawn into air the centrifugal blower from direction of principal axis and make the air-flow deflection by the wheel hub plate of an opposite side that is positioned at suction portion and discharge to centrifugal direction.Thereby, as the screw ventilation that air is axially flowed, inhaled air can not be discharged to outdoor heat converter with original state.Therefore, adopt at outdoor fan under the situation of patent documentation 1 of multiblade fan, after outdoor heat converter suction chamber outer air, use the splashing ring that is arranged on the centrifugal blower to lift up the condensed water that accumulates in the storage part that is arranged at cover inside and in the air-flow of outdoor air, sprinkle water.But, the outdoor air that contains condensed water can not be blown on the outdoor heat converter, but import to the air outlet that is located at the outdoor heat converter next door, and be discharged to the outside of integrated air conditioner with cover.
Also have, adopt at outdoor fan under the situation of patent documentation 3 of turbofan, identical with patent documentation 1, by outdoor heat converter suction chamber outer air, the outdoor air of this suction is directed to centrifugal direction by the air wind deflector.Though in patent documentation 3, do not touch the processing of condensed water, but, the outdoor air of being discharged to centrifugal direction by outdoor fan is not blown on the outdoor heat converter and is directed in the outdoor side vent passages, is discharged to the outside of integrated air conditioner from the air outlet of outdoor heat converter both sides.
As described above, adopt at outdoor fan under the situation of centrifugal blower, make by outdoor heat converter suction chamber outer air.Therefore, by with condensed water sputtering in the outdoor air that sucks, the airflow blow that humidity is uprised can not be improved the heat exchanger effectiveness of outdoor heat converter to outdoor heat converter.The outdoor fan of present embodiment is to adopt centrifugal blower, make condensed water become vaporific and disperse from the outdoor air that centrifugal blower is discharged, the airflow blow that will contain vaporific condensed water is to outdoor heat converter, when having improved the heat exchanger effectiveness of outdoor heat converter, outdoor heat converter with high temperature makes vaporific condensate evaporation, thereby makes it watery condensed water is not discharged to the outside of integrated air conditioner.
Followingly be illustrated with reference to the embodiment of accompanying drawing to integrated air conditioner of the present invention.In the present embodiment, outdoor fan 18 adopts with respect to Fig. 5, direction of rotation shown in Figure 6, and the inclination of blade is the centrifugal blower of the hypsokinesis wing of hypsokinesis.And, at the internal side diameter of the guard shield 18a of outdoor fan 18, be provided with the air suction 18b of portion that sucks air, be provided with the ring 18c that splashes that makes condensed water sputtering at circumference.And a plurality of blade 18d form the shape that is hypsokinesis with respect to direction of rotation between wheel hub plate 18e and guard shield 18a, and the peripheral part of the blade 18d of hypsokinesis is made into to be roughly cylindric with respect to rotating shaft.
In addition, the multiblade fan as shown in figure 13 that adopts in the patent documentation 1 is that the inclination with respect to the direction of rotation blade is the centrifugal blower that leans forward.Also have, the screw ventilation shown in Figure 11 that adopts in the patent documentation 2 is in the rotating shaft direction blade not to be tilted, and with respect to the normal axis of radial direction, can make leaf curling and to the axial fan of rotating shaft direction air-supply.
The outdoor fan 18 of present embodiment is as Fig. 7, shown in Figure 8, with the 18b of the suction portion opening of outdoor fan 18 towards blower fan with motor 17 1 sides, such as shown by arrows suction chamber outer air will be blown into to the air that centrifugal direction is discharged in the chamber 25 that is made of outdoor heat converter 15 and fan house 24.
The suction side of chamber 25 is provided with the mouth circle 26 that is located on the fan house 24.The diameter (internal diameter) of the end of this mouthful circle 26 is littler than the diameter of outdoor fan 18 18b of suction portion.So mouthful circle 26 end is projected into the inboard of the 18b of suction portion, and with the 18b of suction portion overlapping dimension L only.
Therefore, the inside of chamber 25 is mostly covered with respect to the outside, becomes the state that can keep the static pressure higher than the outside.
And usually, the air communication of discharging from centrifugal blower is crossed cover and is induced to certain orientation, but in the present embodiment, is not provided with can be induced to the covers in the chamber 25 and make its direct discharge.Because the air-flow of discharging to centrifugal direction from outdoor fan does not add cover, the air velocity of discharge is slack-off, because the energy of slack-off speed composition is transformed to the composition that static pressure is raise, the static pressure in the chamber 25 increases.Uprise by the static pressure in the chamber 25, and make the back side of air-flow direct current, thereby also can effectively utilize the outdoor heat converter 15 that is positioned at the wheel hub plate 18e back side to the wheel hub plate 18e of outdoor fan 18.
Be elaborated below.When adopting existing this centrifugal blower, the problem that exists is: though make as the outlet of an indoor side air-flow is discharged from preposition, but as when its former state is used for an outdoor side, because the portion of air of having only outdoor heat converter is in circulation, it is then lower that the degree rate is carried out in the heat exchange of remaining outdoor heat converter.
In order to improve the static pressure in space, as mentioned above, cover that encloses lid etc. is not set in this space from the outdoor fan outlet to outdoor heat converter.Therefore, because the static pressure in this space increases, this pressure will be applied on the most outdoor heat converter, because the air of discharging from blower fan flows out between fin then from all surface currents of the pressure that bears outdoor heat converter, so the utilization rate of heat exchanger increases.
Be illustrated with regard to the disposal ability that increases condensed water below.If existing be arranged on the indoor heat converter bottom collect in the dew container of condensate water its amount of condensed water too much, owing to can not handle by outdoor fan, so, ponding portion is set, depositing a large amount of immobilising water, and make the form of making slow inclination between the storage part of dew container and outdoor fan bottom.
In the present embodiment, because the air suction portion of chamber 25 is covered mostly, the ring 18c that splashes that is arranged on the periphery of outdoor fan 18 lifts up the condensed water that is accumulated in outdoor fan 18 bottoms, even disperse in chamber 25, also can the not fly out outside of chamber 25 of the condensed water that disperses by the mouth circle 26 of fan house 24.Therefore, by the upper air suction inlet 12 or the side air suction inlet 13 of casing 4, and make water droplet disperse to outdoor or drip to below situation all will reduce.Thereby, can increase the water yield of utilizing the ring 18c that splashes to lift up, and can improve the disposal ability of utilizing 15 pairs of condensed waters of outdoor heat converter.
Because the disposal ability at the condensed water of an outdoor side improves, thereby can increase the gradient that is arranged on the water guide path 22 between dew container 21 and the storage part 23, so that increase the discharge of condensed water.And, also ponding portion needn't be set.
If increase the gradient of water guide path 22, dew container 21 is increased with respect to the height and position of storage part 23.So, just produce the space in the bottom of dew container 21.Because the existing electrical component case 11 that is arranged on the bottom of room air outlet 10 is configured in this space, the configuration that is arranged at the air outlet 10 of indoor air sucting inlet 9 both sides can produce following favourable situation.
The first, can increase the opening of air outlet 10; The second, the drive motors that driving can be arranged on the wind direction board on the discharge section of air outlet 10 is arranged on the top or the bottom of outlet 10.
Like this, in the present embodiment, owing to electrical component case 11 can be configured in the bottom of dew container 21, thereby, the space (upper space of air outlet 10, air outlet 10 or lower space) adjacent with air suction inlet 9 can be used for various uses, playing increases the such effect of the product design free degree.
On the other hand, when outdoor fan adopts the such screw ventilation of as shown in figure 10 patent documentation 2, be merely able to periphery setting owing to adjust the guide ring of the air-flow of screw ventilation, so the diameter of guide ring increases along the screw ventilation blade.Therefore, the problem of existence is: by blade upspring and the condensed water that splashes from the fly out outside of fan house of the air suction inlet of guiding ring portion, water droplet disperses to outdoor with the outdoor air suction inlet of original state by integrated air conditioner.And as present embodiment, even the internal diameter of mouthful circle 26 is also littler than blower fan external diameter, the spray when fan blade strikes waters also might disperse to the outside from the mouth circle.
But, under the situation of present embodiment, as the 18b of suction portion of the outdoor fan 18 of centrifugal blower because overlapping with the end of the mouth circle 26 of fan house 24, chamber 25 inside and outside becomes most covered state, so, disperse and can not disperse to the outside by the air suction inlet of integrated air conditioner 1 to the spittle of the condensed water of the inside of chamber 25.Therefore, produce such as mentioned above effect.
Encircle the spittle attached to fan house 24 end faces that 18c lifts up by splashing of outdoor fan 18, the end face from fan house 24 drips as shown in Figure 9, with the blade 18d generation collision of outdoor fan 18.The outdoor fan 18 of present embodiment as explained above, blade 18d is with respect to direction of rotation T hypsokinesis, in addition, the peripheral end of blade 18d roughly is cylindric with respect to the rotating shaft of blade 18d.Though the water droplet that falls drops in the A suitable with the outer peripheral face of blade 18d, the B scope one after another, because blade 18d rotates in the T direction, in scope A, blade 18d and the water droplet that falls be with speed separately and collide, in scope B, be to collide with the difference of speed separately.Be about about 1m/s because water droplet arrives the speed of the free-falling on cylindric blade 18d surface, be far smaller than the rotary speed of the periphery of blade 18d, the noise that the collision of water droplet that falls and blade 18d produces can be thought to be produced by the water droplet of scope A.And, the situation of present embodiment is considered: because the water droplet that falls collides with the state on the outer peripheral face C of each sheet of falling blade 18d one after another, thereby the relative velocity of its collision is the velocity of displacement of radial direction of blade 18d and the free speed of fall sum that water droplet arrives cylindric blade 18d surface.
In the present embodiment, because the diameter of outdoor fan 18 is about 290mm, the sheet number of blade 18d is 7, the revolution of outdoor fan 18 is about 1200rpm, the amount of movement L of the circumferencial direction of every blade 18d is about 50mm, so, can think that the relative velocity that blade and water droplet collide is about about 8m/s.
Corresponding therewith, outdoor fan adopts the situation of screw ventilation, as shown in figure 11, because upright blade is on the normal axis of radial direction, so the water droplet that drips from the end face of fan house is that the speed V with the tangential direction of the blade of screw ventilation collides, therefore, be to collide with the relative velocity that the tangential direction speed of synthesizing free-falling water droplet speed and blade obtains, its relative velocity can be thought about about 18m/s.
The noise that produces when the water droplet that falls collides with the blade of rotation is because relevant with energy, thereby, can think proportional with the energy of water droplet with quality m.Because the kinergety P that the water droplet m that collides with relative velocity V has is P=m*V
2/ 2, so the level of the noise the during collision of water droplet and blade is and square being directly proportional of relative velocity.
Under the situation of the outdoor fan 18 of present embodiment, because the relative velocity during collision approximately is 45% of a screw ventilation speed, its energy P reduces to about about 20% with respect to screw ventilation, can obtain the integrated air conditioner 1 of low noise level.
Also have, under the situation of screw ventilation, have the water droplet m of energy P to collide with relative velocity V after owing to disperse to opposite direction with speed V ', the blower fan of rotation has given water droplet m with the energy suitable with these amounts of exercise, and this part can make blower fan consume unnecessary power with motor.But, the outdoor fan 18 of present embodiment, along with dispersing from the peripheral end of blade 18d, the air-flow on the blade 18d surface of flowing through is vaporific owing to be the water droplet that to fall blade 18d surface one after another, so, blower fan there is no need to consume unnecessary energy for water droplet m is dispersed with motor 17, only be that the energy that drives outdoor fan 18 gets final product, and do not expend unnecessary power, can obtain the integrated air conditioner 1 of power conservation type.
Also have, outdoor fan adopts under the situation of multiblade fan, because the water droplet that falls from the fan house end face drops on the cylindric surface of rotating vane of multiblade fan one after another, the noise of water droplet collision diminishes.But, because the blade of multiblade fan leans forward, make the water droplet that falls because the blade of rotation disperses on tangential direction with the relative velocity identical with screw ventilation, and blower fan is identical with screw ventilation with motor, need to consume the unnecessary energy of this part.
The integrated air conditioner 1 of present embodiment, cools off with motor 17 compressor 14 of high temperature and the blower fan of high temperature from the upper air suction inlet 12 of casing 4 and the outdoor air of side air suction inlet 13 suctions with outdoor fan 18.The blower fan of the compressor 14 of outdoor air and high temperature and the high temperature surface temperature with motor 17 is compared, because temperature is quite low, so the blower fan of the compressor 14 of cooling down high-temperature and high temperature is with motor 17 effectively.And, the outdoor air of cooling compressor 14 and blower fan usefulness motor 17 as shown in Figure 7, be drawn into the chamber 25 with motor 17 1 side through port circles 26 from blower fan, when making the condensed water sputtering that is accumulated in outdoor fan 18 bottoms with the ring 18c that splashes, along with the air-flow from the peripheral end of blade 18d changes into vaporific and is dispersed in the air, become moisture is big, humidity is high airflow blow to outdoor heat converter 15.Consequently, outdoor heat converter 15 becomes by the covering of the condensed water of the cold of being condensed by indoor heat converter 16, and becomes moistening surface; Owing to become moistening surface, improved the overall heat-transfer coefficient of outdoor heat converter 15, also can utilize evaporation of water latent heat, so that the heat exchanger effectiveness of outdoor heat converter 15 increases substantially.
Under the situation of patent documentation 1, outdoor fan adopts multiblade fan, on the peripheral part of the guard shield plectane of air suction inlet one side that the multiblade fan blade is installed the ring that splashes is set, and makes condensed water sputtering.But, though outdoor air is sucked from outdoor heat converter one side, and it is vaporific that condensed water sputtering is changed in the outdoor air that sucks, but can not will contain condensed water and become airflow blow more than the moisture to outdoor heat converter, be used for the cooling of outdoor heat converter, but be discharged to outdoor from the air outlet former state that is arranged on the outdoor heat converter side.Also have, in the patent documentation 3, outdoor fan adopts centrifugal blower, but still sucks outdoor air from outdoor heat converter one side, can not make condensed water sputtering in outdoor air, but discharges from the air outlet former state that is arranged on the outdoor heat converter both sides.
As described above, in the present embodiment, upper air suction inlet 12 and side air suction inlet 13 suction chamber outer air from outer container 4, the compressor 14 of cooling down high-temperature and the blower fan of high temperature motor 17, this outdoor air from blower fan with motor 17 one sides mouth circle 26 by fan house 24 sucked thereafter, condensed water sputtering is vaporific to spread in the outdoor air that is drawn into chamber 25 and becomes the air-flow more than the moisture and be blown on the outdoor heat converter, make outdoor heat converter become wetting surface, and improve heat exchanger effectiveness.Also have, to lift up with the ring 18c that splashes by the condensed water that outdoor heat converter condenses, owing to change into tiny vaporific dispersing air-flow from the peripheral end of the blade 18d of outdoor fan 18, can condensed water easily be evaporated, not disperse to the outside of integrated air conditioner 1 and do not make condensed water become water droplet.Also have, be made of one because the ring 18c that splashes of outdoor fan 18 is periphery plectanes with guard shield 18a, so, can guarantee fully under the condition that does not reduce the ring 18c intensity of splashing and blade 18d between distance.Therefore, be arranged on that even condensed water in the storage part 23 of outdoor fan 18 bottoms accumulates too much, because the blade 18d of outdoor fan 18 can not pat the water surface of condensed water, so, when flying condensed water with blade 18d bullet, and when discharging condensed water, do not produce the noise of patting condensed water from the air suction inlet of integrated air conditioner yet.So, can make and handle water yield increase.
Below, an indoor side 8 is illustrated.The treating capacity of the condensed water by making an outdoor side increases, and forms the space in the bottom of dew container 21, by configuration electrical component case 11 in this space, also can increase the design freedom in the space that air outlet 10 is set as mentioned above.But, the part in space is set in the bottom of indoor heat converter 16, if do not change the size of indoor heat converter, then whole height uprises.In addition, if can change the height dimension of indoor heat converter 16, then reduced heat-shift.At this moment, because the diameter of blower fan also diminishes air quantity is also diminished.Below, the embodiment that solves this class problem is described.
Existing blower fan as an indoor side adopts multiblade fan mostly.But indoor fan 19 in the present embodiment also adopts the turbofan of the hypsokinesis wing as shown in figure 14.And, as Fig. 1, shown in Figure 15, be provided with air suction inlet 9 at the central part of deckboard 3, in the both sides of air suction inlet 9 air outlet 10 is set, so that discharge cold wind from the both sides of deckboard 3.By discharging cold wind from the both sides of deckboard 3, and from an air outlet cold wind is discharged to indoor situation and compares, can lower the temperature equably indoor, make cold wind can deliver to indoor wideer scope.Also have, also can air outlet be set on the top of air suction inlet 9.At this moment, owing to produce the air-flow flow to ceiling, can make indoorly has ground, dead angle not lower the temperature.
Also have, when integrated air conditioner 1 is installed, can removes because of the position of air outlet makes cold wind be blown into whole room near wall etc. and produce this restriction of difficulty mounting condition.
The air quantity of centrifugal blower-static pressure property list is shown among Figure 17.The air quantity of the turbofan of the hypsokinesis wing-static pressure characteristic curve is I, and the characteristic curve of the multiblade fan of the wing that leans forward is expressed as II.Therefore, when air quantity was identical, the static pressure of centrifugal blower was little with the turbofan of the hypsokinesis wing than the multiblade fan of the wing that leans forward, because it is less to cough the expansion angle that makes cover, so, can relatively hold centrifugal blower and cover in the narrow space.
Indoor fan adopts under the situation of multiblade fan, and as shown in figure 16, it is big that the widening angle of the cover of multiblade fan becomes, because the leading section of cover is roomy, just has the tendency of sending cold wind from the bottom and the top of air outlet.Also have, because static pressure uprises, the mobile peripheral direction of being partial to along cover of cold wind can not be discharged from whole air outlet equably from the cold wind that air outlet is discharged, and discharges cold wind from the direction of the end deflection arrow of the opposite side of the air outlet of sending cold wind.
In the present embodiment, in order to solve above-mentioned problem, adopt the turbofan of the hypsokinesis wing as indoor fan 19.As explained above, because the widening angle of the cover 20 of indoor fan 19 can be less, the position that the leading section of cover 20 can be broadened reduces.As shown in figure 15, the position that the leading section of cover 20 is broadened and the height of air outlet 10 are made roughly the same height, make it laterally send cold wind from air outlet 10.Therefore, the cold wind that the minimizing of reduction static pressure can be departed from makes cold wind discharge equably from whole air outlet 10 from the horizontal air-supply of air outlet 10.
Also have, adopt at indoor fan under the situation of Figure 16 of multiblade fan, because the widening angle of cover is bigger, the space that stores electric component has only utilized the peristome space of cover.Therefore, the storage area of electric component is subjected to the restriction of cover aperture position, owing to be configured in any side in the left and right sides of integrated air conditioner, when integrated air conditioner is installed, in order not allow the operating portion of electric component make operating difficulties near metope, the operating portion that produces electric parts leaves the such problem of installing of metope.
As explained above,, can reduce the widening angle of cover 20, compare, can also make the shape miniaturization of the blower fan that contains cover 20 with the situation that adopts multiblade fan because indoor fan 19 adopts turbofan.
For this reason, can increase the height of the position of dew container 21,, not only can guarantee the air quantity of blower fan but also not increase the height of whole assembly even at its underpart configuration electrical component case 11.
, as shown in figure 18, base 5 is because the weight of the parts that supporting component 2 is loaded, thus with jam-packed around the base 5 to top and stile 5a is set to guarantee necessary strength.Therefore, have the height dimension H of the electric component 11 of operating portion even can guarantee the top that is stored in base 5, thus H ' become owing to have stile 5a effective depth, thereby can not utilize the upper space of base 5.Therefore, in the present embodiment, by in the upper space of the base 5 that stile 5a is arranged, not storing electric component 11 with operating portion, and in the bottom of the base 5 of a relative side with stile 5a, the space 5b (with reference to Fig. 2) that stores the electric component 11 with operating portion is set, thereby the electric component 11 that will have operating portion is stored in herein.That is, the space of adopting turbofans to produce by indoor fan 19 uprises dew container 21, and the base 5 of dew container 21 bottoms is extruded into the height of dew container 21, thereby the electric component 11 that will have an operating portion is stored in the bottom of base 5.
Thus, for the stile 5a former state of the intensity of guaranteeing base 5 keeps, owing to the electric component 11 that operating portion is arranged can be configured in the central part of deckboard 3, thereby the restriction condition can under the situation of the intensity of not damaging integrated air conditioner 1, eliminate installation the time.Also have, be stored in the bottom of base 5 by the electric component 11 that will have operating portion, in the electric component 11 that operating portion is housed, just in case break down when carrying out maintenance activity, can handled easily, shorten maintenance time, the raising operating efficiency.
In addition, owing to the height of dew container 21 can be increased to than existing height height, can add the gradient that condensed water in senior general's dew container 21 imports the water guide path 22 in the storage part 23 be arranged on outdoor fan 18 bottoms, condensed water is overflowed from dew container 21 and water guide path 22 and can reliably water be transported to storage part 23.Also have,,, can thicken the heat-barrier material of dew container 21 bottoms, improve its effect of heat insulation, thereby eliminate the problem that makes electric component 11 dewfall because of the heat conduction with operating portion for the height space that can not effectively utilize because the stile 5a of base 5 is arranged.
And then, be arranged on the central part of integrated air conditioner 1 by the electric component 11 that will have operating portion, owing to can guarantee free space in the bottom of air outlet 10, thereby micro-machine can be configured in this space, wind deflector plate of being arranged on air outlet 10 etc. can be turned round automatically.Also have, in the present embodiment, though to about the air outlet 10 that is provided with of 2 positions be illustrated, but, because the widening angle of cover 20 diminishes, and then a plurality of air outlets can be set, and makes it can discharge cold wind equably in the scope of the broad in room.
Also have, in the present embodiment, only integrated air conditioner 1 is illustrated, switches to cooling operation and heating operation and other methods of operation and turn round, can obtain above-mentioned effect separately in service by structure with freeze cycle with regard to the cooling aspect.
As mentioned above, if outdoor fan adopts screw ventilation, there are the following problems.Periphery at the screw ventilation blade is equipped with the ring that splashes that is used to lift up condensed water.But,, when strengthening the external diameter of screw ventilation, will make the blower fan external diameter quite near the external diameter that splashes and encircle that is arranged on the screw ventilation periphery for the strong wind of realizing screw ventilation quantizes.Therefore, the water yield more than, the part of screw ventilation will lift up condensed water.The incident because the front end of screw ventilation blade and the water surface roughly meet at right angles, if the blade of this screw ventilation lifts up water, the blade of blower fan will directly be patted water, and the water of beating is disperseed to a plurality of directions.At this moment, the sound when screw ventilation is directly patted water and produce noise owing to the water of upspringing collides box house, these sound become the obstacle that reduces noise.Also have, especially the problem of Cun Zaiing is, in an outdoor side box body, is used to suck the intake of outside air to box house though be provided with, and the condensed water that disperses disperses to outdoor from intake against the flow direction of wind.Also the problem of Cun Zaiing is, directly pats condensed water because of screw ventilation, and the input of pressure fan motor is raise.
In the present embodiment, though adopt the turbofan of making the wing shape of hypsokinesis, this mainly is for solving following problem.In addition, though enumerated these problems, in the present embodiment with these problems as target and obtained effect, rather than be used for limiting the present invention.
Upstream side (upstream of wind) at condenser disposes in the air conditioner of outdoor fan, the 1st is to result from the problem of blower fan boosting, promptly, the problem that solves is: be accompanied by the problem that can not carry out sufficient heat exchange in the adverse current of the middle body of condenser, result from the discharge of outer peripheral portion, at the short circuit problem of the adverse current of inner-diameter portion whose, for the wing with blower fan carries out big air diverts, air-flow causes on aerofoil to be peeled off, when noise increases, because of the remarkable problem that descends of stall efficient.The 2nd is to result from the ring and lift up the problem of condensation by the blade peripheral part of splashing that is arranged on the blower fan peripheral part, promptly, the problem that solves is: the sound that the blade of blower fan produces when directly patting water, because of the water of upspringing collides the sonorific problem of box house, because of blower fan is directly patted the problem that condensed water raises the input of pressure fan motor.The 3rd is the problem of dispersing that solves the condensed water of discharging from the intake that is used to suck outside air and from the condenser discharge portion.
Below, the outdoor fan that is applicable to this integrated air conditioner is elaborated, but before this its main points is carried out simple explanation.
The 1st, the blower fan (centrifugal fan) that constitutes by wheel hub, a plurality of blade and guard shield, though the external diameter with blade diminishes or change poles point is arranged but still is the blade of the form that diminishes in the direction from guard shield one side direction wheel hub one side, at the peripheral part of guard shield, be provided with ring with the dew effect of dispersing and external diameter ring-shaped structure bigger than blade external diameter.
The 2nd, at the wheel hub peripheral part of above-mentioned centrifugal blower, it is bigger than blade external diameter to be provided with external diameter, and has the circle of the ring-type of discharging the hole that air passes through.
The 3rd, at the peripheral part of the blade of the centre of guard shield that is positioned at above-mentioned centrifugal blower and wheel hub, be provided with the circle of the ring-type in the hole that air passes through.
The 4th, having wheel hub, a plurality of blade and guard shield and having in the centrifugal blower of endless loop of the condensation effect of dispersing in guard shield one side setting, though the external diameter with blade diminishes or change poles point is arranged but still is the blade of the form that diminishes in the direction from guard shield one side direction wheel hub one side, and on meridian plane, have it and be shaped as the shape that has 2 change poles points at least and the air-flow guard shield axially of discharge.
The 5th, have the centrifugal blower of the ring of above-mentioned ring-type, though the external diameter with blade diminishes or change poles point is arranged but still is the blade of the form that diminishes in the direction from guard shield one side direction wheel hub one side, its structure is: the blade external diameter of wheel hub one side is less than 85% of the blade external diameter of guard shield one side, the internal diameter blade of guard shield one side is greater than 75% of the blade external diameter of guard shield one side, the blade exit width is greater than 25% of the blade external diameter, and wheel hub one lateral lobe sheet internal diameter is less than 75% of blade external diameter.
The 6th, in the centrifugal blower of the ring that has above-mentioned ring-type, when the blade exit width greater than 30% of wheel hub external diameter, perhaps, wheel hub one lateral lobe sheet internal diameter between blade and blade, was provided with internal diameter than the big vanelets of wheel hub one lateral lobe sheet internal diameter less than 50% o'clock of the blade external diameter.
Illustrate that with Figure 19 and Figure 20 the centrifugal blower of present embodiment, Figure 19 and Figure 20 are the schematic perspective view and the meridian plane shape figure of expression centrifugal blower.

LGuard shield 18a periphery on, make have ring-type splash the ring 18c structure.This ring 18c that splashes also can make the shape that condensation can be lifted up effectively like that among the figure, is this peripheral part with spool parallel and be shape cylindraceous.
The ring 18c that splashes of centrifugal blower 18 is because blade maximum outside diameter D
2Outer diameter D with the ring 18c that splashes

LRelation be D
2S
L＞D
2, at distance blade maximum outside diameter D
2The ring 18c that splashes suitably is housed on the position of distance, so, the situation in the blade 18d immersion condensed water can take place hardly.
For example, even water level rises to the position that blade 18d is dipped into condensed water, because this centrifugal blower is that worm-gear type blower fan, its blade are made the wing shape of hypsokinesis, because the wing surface of blade 18d passes through at surface of water, the water that splashes disperses from air suction inlet and reduces to the possibility of outside.On the other hand, under the situation of screw ventilation, because the blade of screw ventilation is an acute angle with respect to the incidence angle of the water surface, blade strikes waters with acutangulating, and the problem of existence is: around the water that splashes disperses and expands to and a part is dispersed outside off-premises station.
Therefore,, only carry out usually, make that the noise when lifting up water reduces with the ring 18c that splashes owing to lift up condensed water as perfect condition.Also have, if when centrifugal blower installed as outdoor fan, the intet diameter D of centrifugal blower
1S is littler than the bore of existing screw ventilation, owing to condensed water does not almost splash on the direction different with outdoor heat converter one side, thereby, there is not condensed water to disperse away from the air suction inlet that is arranged on the outdoor side box body.Therefore, can be under evaporated condensation water disperse situation outside outdoor, machine, increase the outlet capacity of raising of the ring 18c that splashes, can increase the disposal ability of condensed water.
In addition, by the shape of blade 18d being made maximum outside diameter D with respect to guard shield one side
2, wheel hub one side outer diameter D
2H is D
2＞D
2H, the wind speed, air quantity ground that generally can increase wheel hub one side suitably adjust the wind speed of the exit width direction of centrifugal fan, when air quantity distributes, can reduce the workload of the pressure fan of this part wheel hub one side, compare with the centrifugal blower of the existing blade shape that has almost the blade external diameter parallel, verifiedly make the power consumption of blower motor reduce about about 8% with rotating shaft.Therefore, by adopting this centrifugal blower 18 can make blower motor save electric power.
Below, use Figure 21 and Figure 22 that the embodiment of other centrifugal blower is illustrated.
The position that centrifugal blower 18 distance wheel hub 18f peripheries have a certain intervals is provided with the ring 18c that splashes of ring-type, and wheel hub 18f and splash and encircle 18c and be connected with a plurality of pillars 201 makes the structure that is provided with space 202 between each pillar 201.For example, the external diameter of blade 18d make change poles point with almost parallel being arranged alternately of rotating shaft, on the ring that splashes of the blade-section that change poles point is arranged, the hole is set, and connects wheel hub 18f and splash with other blade-section and have the effect that can be configured as one when encircling 18c.
Below, use the example of above-mentioned centrifugal blower 18 to be illustrated to the outdoor crosswind machine of integrated air conditioner.The ring 18c that splashes of centrifugal blower is owing to be arranged on wheel hub 18f side, making the ring 18c that splashes and being configured near the outdoor heat converter 107 structure.Thereby the ratio that will directly be blown on the heat exchanger with the condensed water that the ring 18c that splashes lifts up increases, and makes it carry out high efficiency heat exchange process to condensed water.Therefore, the treating capacity of condensed water is increased, water is accumulated in the dew container that is arranged at the indoor heat converter bottom temporarily, and not adopt water-storing device; Can under having the situation of remaining condensed water, water be transported in the storage part that is arranged at the outdoor fan bottom.Its result can make the height and position of dew container higher than the storage part, can dispose the electric component case in the space of the sky of the bottom of this dew container, and this point is identical with above-mentioned various embodiment.
Another embodiment that Figure 23 and Figure 24 splash and encircle in above-mentioned wheel hub 18f one side setting.It is that the external diameter that encircles 18a one side direction wheel hub 18f one side from splashing diminishes that the external diameter of blade 18d changes, perhaps, be while having the structure that change poles point diminishes, but, owing to will splash ring 18c be contained in another component form that wheel hub 18f goes up or wheel hub 18f near, so, have and produce the air-supply effect and the effect of splashing to greatest extent.
Below, use Figure 25 and Figure 26 that other embodiment is illustrated.
By on the blower fan of the outdoor side of integrated air conditioner, using above-mentioned centrifugal blower 18, except that having the same effect with the foregoing description, can also one side turn to direction arbitrarily in the downstream with the direction from the air-flow of discharging between guard shield 18a and the wheel hub 18f, have the effect of the loss of the air that can reduce discharge.
Among the figure, though the ring 18c lopsidedness downstream that splashes can adopt and can bring into play the air-supply effect to greatest extent and the shape of the effect of splashing.
Below, with Figure 27 another embodiment is described.Centrifugal blower 18 is by constituting with lower member: be provided with the wheel hub 18f with propeller boss 18g of transmission by the revolving force of blower motor generation in rotating center section; Be configured in a plurality of blade 18d on the wheel hub 18f at certain intervals; The guard shield 30 that is connected with each blade in the opposite side of wheel hub 18f.On the shape of the discharge portion 30a of guard shield 30 is formed in axially.Peripheral part at guard shield 30 is equipped with the ring 18c that splashes.
Usually, centrifugal blower will along the circumferential direction be discharged from the fluid that suction inlet 401 sucks, and utilize centrifugal blower 18, and the fluid that sucks from suction inlet 401 then produces along guard shield 30 in axial flowing.
By on an outdoor crosswind machine of integrated air conditioner, using centrifugal blower 18, owing to will directly discharge vertically from the axial inhaled air of pressure fan, it can be blown on the outdoor heat converter, therefore, can be to the radiating surface of heat exchanger air supply equably.Also have, utilize the ring 18c that splashes to obtain the effect same with the foregoing description.
Each parts to the centrifugal blower of above explanation describe below, are that example is illustrated with centrifugal blower shown in Figure 1.
Centrifugal blower shown in the embodiment 1-4 is made of following: the blade outer diameter D of wheel hub one side
2H is less than the blade outer diameter D of guard shield one side

According to the centrifugal blower of present embodiment, and compare with the existing centrifugal blower of identical air quantity as benchmark, its effect is: make its work the electric power that must consume can save 8%, the noise of relevant generation with its work also can reduce 1.5dB.
Below, adopt Figure 28 that other embodiment is illustrated.Centrifugal blower 18 shown in the embodiment 1-5 is at its blade exit width b
