The specific embodiment
Below, the specific embodiment of air conditioner of the present invention (indoor set of air conditioner specifically) is described.In each following embodiment, be example explanation the present invention with the wall indoor unit.In the figure shown in each embodiment, the shape of each unit (or component parts of each unit), size etc., also some situation inequality.
< essential structure >
Fig. 1 is the profilograph of indoor set of the air conditioner of expression embodiment of the present invention 1.Fig. 2 is the stereoscopic figure of this indoor set of expression.This embodiment 1 and after in the embodiment stated, describe the front face side of the left side of Fig. 1 as indoor set 100.The structure of indoor set 100 is described based on Fig. 1 and Fig. 2 below.
(unitary construction)
This indoor set 100, the freeze cycle through utilization circulates cold-producing medium supplies to the indoor air-conditioning subject area that waits to Air Conditioning.Indoor set 100 mainly has housing 1, fan 20 and heat exchanger 50.Housing 1 is formed with and is used for suction inlet 2 that absorbs room air and the blow-off outlet 3 that is used for supplying to Air Conditioning the air-conditioning subject area.Fan 20 is accommodated in this housing 1, sucks room air from suction inlet 2, blows out Air Conditioning from blow-off outlet 3.Heat exchanger 50 is provided in from fan 20 to blow-off outlet on 3 the wind path, produces Air Conditioning through between cold-producing medium and room air, carrying out heat exchange.By these inscapes, in housing 1, be communicated with wind path (arrow Z).Suction inlet 2 forms at the upper opening of housing 1.(specifically, be at housing 1 front face downside) opening forms blow-off outlet 3 in the bottom of housing 1.Fan 20 is provided in the downstream of suction inlet 2 and the upstream side of heat exchanger 50, for example is made up of axial-flow type or mixed flow fan etc.
In the indoor set 100 that constitutes like this; Because fan 20 is located at the upstream side of heat exchanger 50; So, compare with the indoor set that is located at fan 20 air conditioner before at blow-off outlet 3 places, can suppress to produce the inequality of eddy flow, wind speed profile from the air that blow-off outlet 3 blows out.Therefore, can carry out comfortable air-supply to the air-conditioning subject area.In addition, owing to there is not complicated structure such as fan at blow-off outlet 3 places, so, in the dewfall of the intersection generation of hot gas and cold air, also can easily tackle during for cooling operation.In addition, be cold air, hot gas because fan motor 30 is not exposed to Air Conditioning, so, can be provided long running life.
(fan)
Usually, there is restriction aspect the space in the indoor set of air conditioner being provided with, so fan mostly can not be very big.Therefore, in order to obtain required air quantity, the also fan of a plurality of modest size of row arrangement.The indoor set 100 of this embodiment 1, as shown in Figure 2, along the length direction (in other words, the length direction of blow-off outlet 3) of housing 1, and row arrangement 3 fans 20.According to the indoor set size of now common air conditioner, in order to obtain required heat-exchange capacity, fan 20 is preferably roughly 3～4.In the indoor set of this embodiment 1, fan 20 all is identical shape, and all with identical working speed running, thereby all fans 20 can obtain roughly the same air output.
By such structure, the flowing resistance inner according to institute's required airflow, indoor set 100 makes up number, shape and the size etc. of fan 20, can obtain the best fan design corresponding with the indoor set of plurality of specifications 100.
(horn mouth)
The indoor set 100 of this embodiment 1 is disposing the horn mouth 5 on the pipeline around fan 20.Horn mouth 5 is used for guiding swimmingly the air-breathing and exhaust of fan.As shown in Figure 1, the horn mouth 5 of this embodiment 1 sees it is circular from the plane.In the vertical section, the horn mouth 5 of this embodiment 1 has following shape.Top 5a forms its end and expands the roughly circular arc of opening towards the top.Central portion 5b is that bell-mouthed diameter is certain upstanding portion.Bottom 5c is that the roughly circular arc of opening is expanded in its end towards the below.End (circular arc portion of suction side) by the top 5a of horn mouth 5 has formed suction inlet 2.
In order to reduce component number and to improve intensity, horn mouth 5 for example also can form as one with housing 1.In addition, for example also can it can be loaded and unloaded modularizations such as horn mouth 5, fan 20 and fan motor 30 with respect to housing 1, like this, can improve maintainability.
In this embodiment 1, the end of the top 5a of horn mouth 5 (circular arc portion of suction side), with respect to the opening surface of horn mouth 5 circumferentially, be identical shape.That is, be the direction of rotation at center at rotating shaft 20a with fan 20, horn mouth 5 does not have the structure of breach, rib etc., is the uniform shape with axial symmetry.
Through such formation horn mouth 5, because the end (circular arc portion of suction side) of the top 5a of horn mouth 5 is uniform shape with respect to the rotation of fan 20, so, as the inlet flow of fan 20, also realize uniform airflow.Therefore, can reduce the noise that the bias current because of the inlet flow of fan 20 produces.
(demarcation strip)
As shown in Figure 2, the indoor set 100 of this embodiment 1 is provided with demarcation strip 90 between adjacent fan 20.These demarcation strips 90 are arranged between heat exchanger 50 and the fan 20.That is, the wind path between heat exchanger 50 and the fan 20 is divided into a plurality of wind paths (in this embodiment 1 being 3).Because demarcation strip 90 is arranged between heat exchanger 50 and the fan 20, so the end of a side of joining with heat exchanger 50 is the shape along heat exchanger 50.Specifically, as shown in Figure 1, (that is, see the vertical section of indoor set 100 from the front face side of indoor set 100 to the vertical section of rear side from the right side.Be called the vertical section, right side below) in, heat exchanger 50 is configured to roughly Λ shape.Therefore, the end of leaning on heat exchanger 50 1 sides of demarcation strip 90 also is a Λ shape roughly.
The position of the end of leaning on fan 20 sides of demarcation strip 90 for example can determine as follows.Far away and do not produce under the interactional situation in the suction side at a distance of enough when adjacent fan 20, the exit face that the end by fan 20 sides of demarcation strip 90 extends to fan 20 gets final product.But; At adjacent fan 20 at a distance of closer and produce in the suction side when influencing each other; And; When the shape in the end of the top of horn mouth 5 5a (circular arc portion of suction side) can form enough greatly, the end of leaning on fan 20 sides of demarcation strip 90 also can with the mode that do not influence adjacent wind path (with adjacent fan 20 in the suction side not interactional mode) extend to the upstream side (suction side) of fan 20 always.
As stated, the wind path between heat exchanger 50 and the fan 20 is divided into a plurality of wind paths (in this embodiment 1 being 3).In this wind path, promptly on demarcation strip 90, housing 1 etc., sound-absorbing material is set, can reduce the noise that produces in the pipeline.
In addition, these divided wind paths are seen from the plane, and forming the length of side is the roughly quadrangle of L1 and L2.That is, the width of divided wind path is L1 and L2.Therefore, for example, be arranged on air quantity that the inner fan 20 of the roughly quadrangle that formed by L1, L2 produced effectively through be positioned at fan 20 downstream, by the heat exchanger 50 of L1, L2 area surrounded.
Like this, through being divided into a plurality of wind paths to the wind path in the housing 1, even there is the cycle composition in the flow field that fan 20 forms in downstream, the air that blows out from each fan 20 can not freely move at the length direction (with the direction of Fig. 1 paper quadrature) of indoor set 100.Therefore, the air that blows out of fan 20 can through these fan 20 downstream, by the heat exchanger 50 of L1, L2 area surrounded.As a result, can suppress to flow into the inequality that the air quantity of indoor set 100 length directions (with the direction of Fig. 1 paper quadrature) of whole heat exchanger 50 distributes, thereby have high heat exchange performance.In addition, through with demarcation strip 90 with separating in the housing 1, in 20 in adjacent each other fan, can prevent the interference of the eddy flow that adjacent fans 20 produces.Therefore, the fluid energy loss that the phase mutual interference because of eddy flow produces can be suppressed, the pressure loss of indoor set 100 can be when improving wind speed profile, reduced.In addition, each demarcation strip 90 not necessarily will use a plate to form, and also can use the polylith plate to form.For example, also side heat exchanger 51 sides and rear side heat exchanger 55 sides in front are divided into two demarcation strip 90.Certainly, the position that is bonded with each other of each plate of formation demarcation strip 90 is preferably very close to each other.Through being divided into demarcation strip 90 a plurality of assembleabilities that improve demarcation strip 90.
(fan motor)
Through adopt cost than higher DC brushless motor as fan motor 30, can raise the efficiency, realize long lifetime and improve controlled.But, even adopt the motor of other form, also can satisfy elementary function as air conditioner, this is self-evident.
In addition, the circuit of the driving usefulness of fan motor 30 can become one with fan motor 30, also can externally constitute and implement dustproof, fireproof countermeasure.
In addition, the drive circuit of fan motor 30 can constitute in the inside of fan motor 30, also can be externally.
(motor support)
(heat exchanger)
The heat exchanger 50 of the indoor set 100 of this embodiment 1 is configured in the downwind side of fan 20.This heat exchanger 50 for example can adopt fin tube type heat exchanger etc.As shown in Figure 1, in the vertical section, right side, heat exchanger 50 is cut apart by line of symmetry 50a.Line of symmetry 50a is divided into left and right directions to the scope that is provided with of the heat exchanger in this section 50 in substantial middle portion.That is, front face side heat exchanger 51 is configured in front face side (paper left side among Fig. 1) with respect to line of symmetry 50a, and rear side heat exchanger 55 is configured in rear side (paper right side among Fig. 1) with respect to line of symmetry 50a.Front face side heat exchanger 51 is configured in the housing 1 with rear side heat exchanger 55 in this wise: open with respect to the flow direction expansion of air at the interval that front face side heat exchanger 51 and rear side heat exchanger are 55; Promptly; In the vertical section, right side, the section shape of heat exchanger 55 is roughly Λ shape.That is to say that front face side heat exchanger 51 disposes with the mode with inclination with the flow direction of rear side heat exchanger 55 with respect to the air of supplying with from fan 20.
In addition, heat exchanger 50 is characterised in that the wind path area of rear side heat exchanger 55 is greater than the wind path area of front face side heat exchanger 51.That is, for heat exchanger 50, the air quantity of rear side heat exchanger 55 is greater than the air quantity of front face side heat exchanger 51.In this embodiment 1, in the vertical section, right side, the length direction length of rear side heat exchanger 55 is longer than the length direction length of front face side heat exchanger 51.Like this, the wind path area of rear side heat exchanger 55 is greater than the wind path area of front face side heat exchanger 51.In addition, other structure (among Fig. 1 the length of depth direction etc.) of front face side heat exchanger 51 and rear side heat exchanger 55 is identical.That is, the heat transfer area of rear side heat exchanger 55 is greater than the heat transfer area of front face side heat exchanger 51.In addition, the rotating shaft 20a of fan 20 is arranged on the top of line of symmetry 50a.
Through such formation heat exchanger 50, compare with the indoor set of the air conditioner before that is located at fan blow-off outlet, can suppress to produce the inequality of eddy flow, inhibition wind speed profile from the air that blow-off outlet 3 blows out.In addition, through such formation heat exchanger 50, the air quantity of rear side heat exchanger 55 is greater than the air quantity of front face side heat exchanger 51.Poor by this air quantity, the air that has passed through front face side heat exchanger 51 and rear side heat exchanger 55 respectively is when the interflow, and the air behind this interflow is towards front face side (blow-off outlet 3 sides) bending.Therefore, needn't make air-flow crooked sharp near blow-off outlet 3, can reduce near the pressure loss the blow-off outlet 3.
In addition, in the indoor set 100 of this embodiment 1, the flow direction of the air that flows out from rear side heat exchanger 55 be from rear side towards the front side flow.Therefore, the indoor set 100 of this embodiment 1 is compared when in the vertical section, right side, being configured to roughly v shape to heat exchanger 50, passed through behind the heat exchanger 50 air flow crooked more easily.
For this reason, in this embodiment 1, adopt fin tube type heat exchanger as heat exchanger 50 (front face side heat exchanger 51 and rear side heat exchanger 55), to realize the miniaturization of heat exchanger 50.Specifically, the heat exchanger 50 of this embodiment 1 has a plurality of heat-transfer pipes 57 that separate the stacked a plurality of fins of predetermined gap 56 and these fins 56 of perforation.In this embodiment 1, the left and right directions of housing 1 direction of paper quadrature (among the Fig. 1 with) stacked fin 56.That is, heat-transfer pipe 57 runs through fin 56 along the left and right directions of housing 1 (with the direction of the paper quadrature of Fig. 1).In addition, in this embodiment 1, in order to improve the heat exchanger effectiveness of heat exchanger 50,2 biographies heat pipes 57 have been disposed in the direction of ventilation (width of fin 56) of heat exchanger 50.These heat-transfer pipes 57 are roughly staggered configuration in the vertical section, right side.
Heat-transfer pipe 57 is made up of the pipe of diameter thin (about diameter 3mm～7mm), the cold-producing medium of the heat-transfer pipe 57 of flowing through (indoor set 100 with have the cold-producing medium that uses in the air conditioner of this indoor set 100) be R32, like this, can realize the miniaturization of heat exchanger 50.That is, in heat exchanger 50, heat-transfer pipe 57 inner cold-producing medium and the room airs of flowing through carry out heat exchange via fin 56.Therefore, when adopting thin heat-transfer pipe 57, compare with the heat exchanger that the heat-transfer pipe diameter is thick, under identical circulating mass of refrigerant, the pressure loss of cold-producing medium increases.But R32 compares with R410A, and the evaporation latent heat under uniform temp is big, and available circulating mass of refrigerant is still less brought into play identical ability.Therefore,, used refrigerant amount can be cut down, in heat exchanger 50, the pressure loss can be reduced through using R32.Therefore, through constituting heat-transfer pipe 57 and adopt R32, can make heat exchanger 50 miniaturizations as cold-producing medium with thin pipe.
In the heat exchanger 50 of this embodiment 1,, can realize the lightweight of heat exchanger 50 through forming fin 56 and heat-transfer pipe 57 with aluminum or aluminum alloy.When the weight of heat exchanger 50 did not become the restriction of installing, heat-transfer pipe 57 also can constitute with copper.
In addition, in this embodiment 1, miniaturization and lightweight have been realized in vertical section, the right side roughly heat exchanger 50 of Λ shape, and still, the shape of heat exchanger 50 is not limited thereto.Heat exchanger 50 by fin 56 and heat-transfer pipe 57 constitute for example also can be formed as follows.
Figure 10～Figure 13 is the profilograph of another routine indoor set of expression embodiment of the present invention 1.
In the vertical section, right side; Heat exchanger 50 by fin 56 and heat-transfer pipe 57 constitute for example also can form roughly N shape (Figure 10), for example also can form roughly W shape (Figure 11); For example also can form roughly И shape (Figure 12), for example also can form roughly M shape (Figure 13).At this moment, the heat exchanger 51a and the heat exchanger 51b that are configured in line of symmetry 50a front side become front face side heat exchanger 51.In addition, the heat exchanger 55a and the heat exchanger 55b that are configured in line of symmetry 50a rear side become rear side heat exchanger 55.Through as Figure 10～13, constituting heat exchanger 50, through the air quantity increase of heat exchanger 50, the heat-exchange capacity of heat exchanger 50 improves more.Therefore, can make heat exchanger 50 miniaturization more.
(handguard parts and filter)
The indoor set 100 of this embodiment 1 is provided with handguard parts 15, filter 10 at suction inlet 2 places.Handguard parts 15 are from preventing that the purpose that hand touches the fan 20 that is rotating is provided with.Therefore, the shape of handguard parts 15 is arbitrarily, gets final product so long as hand can not touch the shape of fan 20.For example, the shape of handguard parts 15 can be a clathrate, also can be the circle that is made up of a plurality of rings that vary in size.In addition, handguard parts 15 can constitute with materials such as resins, also can constitute with metal material, but when needing intensity, hope to constitute with metal.In addition, consider material and shape that handguard parts 15 are preferably thin as far as possible, intensity is big with the viewpoint that keeps intensity from reducing flowing resistance.Filter 10 is provided with for the inside that prevents dust inflow indoor set 100.Filter 10 releasably is located on the housing 1.In addition, the indoor set 100 of this embodiment 1 has the automatic sweeping machine structure of scavenge filter 10 automatically.
