Summary of the invention
The object of the present invention is to provide and a kind ofly can suppress short circuit and tempered air is blowed efficiently to air conditioner at a distance, to address the above problem.
Solve the means of problem
In order to address the above problem, air conditioner of the present invention is characterised in that, possess: have suction inlet at upper surface and have blow-off outlet in the front surface bottom, and be formed with the housing of air flow circuit from above-mentioned suction inlet to above-mentioned blow-off outlet, the fan of blowing, and the wind-guiding panel that covers above-mentioned blow-off outlet and extend upward from blow-off outlet, above-mentioned wind-guiding panel is set to, but near the axis around the lower shaft of setting abreast with the housing left and right directions the following ora terminalis of blow-off outlet rotates and the freely openable blow-off outlet, the wind-guiding face that forms the concave curved surface shape is formed on the medial surface of above-mentioned wind-guiding panel, when the rotation of wind-guiding panel became the attitude of open blow-off outlet, the wind-guiding face of this concave curved surface shape was continuous with the downside wall of the concave curved surface shape that constitutes the air flow circuit from the said fans to the blow-off outlet.
According to said structure, rotating the wind-guiding panel in order to blow out tempered air when becoming the attitude of open blow-off outlet from blow-off outlet, the wind-guiding face and the downside wall of cover portion form the concave curved surface shape continuously, therefore can be not random along the air-flow that forms the tempered air that blows out towards the slightly downward air flow circuit of blow-off outlet, can its direction be guided to slightly top, housing front side smooth-goingly, suppress short circuit and efficiently tempered air is blowed at a distance.Here, so-called wind-guiding face is meant on the wind-guiding panel side surface of the air that contact blows out from blow-off outlet, the dorsal surface of the wind-guiding panel when promptly the wind-guiding panel becomes the covering attitude of sealing blow-off outlet.
Above-mentioned wind-guiding panel is made of the parts of establishing in addition of the elongated surfaces plate body of cover plate body that covers blow-off outlet and elongation hood panel body, cover plate body and elongated surfaces plate body can be integratedly around the axis rotation of above-mentioned lower shaft.
Therefore according to said structure, the length of wind-guiding panel forms the length that the cover plate body is cooperated with the elongated surfaces plate body, promptly forms greatlyyer than the following ora terminalis and the length between the last ora terminalis of blow-off outlet, can efficiently tempered air be blowed at a distance.And because the cover plate body is made of different parts with the elongated surfaces plate body, therefore can make the action individually respectively of each parts, make blow-off direction variation thus from the air of blow-off outlet.
Particularly, but can the cover plate body be set to end thereon and rotate and the freely openable blow-off outlet around the axis of setting abreast with the housing left and right directions of going up axle.In said structure, keep the state of elongated surfaces plate body covering shell, the cover plate body is rotated around the axis of last axle, thereby the air from blow-off outlet can be blowed to the housing below.
Thus, can correspondingly blow out tempered air efficiently with operation mode.Here, lower shaft is set in the bottom of wind-guiding panel and goes up the upper end that axle is set in the cover plate body.Lower shaft all is set at parallel with the housing left and right directions with last axle.
In addition, if when rotating into the attitude into open blow-off outlet at above-mentioned cover plate body, form the upside wall of the air flow circuit of formation from the said fans to the blow-off outlet with the continuous mode of the wind-guiding face of the concave curved surface shape of cover plate body, even then from blow-off outlet downwards under the situation of blow out air, can not produce air turbulence yet and can carry tempered air smooth-goingly.
Particularly, the upside wall can form in above-mentioned air flow circuit to tilt upward towards blow-off outlet.According to said structure, the wind-guiding face of the concave curved surface shape of upside wall and cover plate body can form continuous face, carries tempered air smooth-goingly.
In addition, the wind-guiding face of cover plate body can be formed the concave curved surface shape, the wind-guiding face of elongated surfaces plate body forms and the opposite convex surface shape of above-mentioned cover plate body.Thus, can integrally be modified to, thereby suppress the short circuit of tempered air more effectively have the direction that general plan forward blows out the tempered air of trend upward in cover portion towards the place ahead.
Promptly, in the present invention, different with the common barrier that in air stream, is provided with like that for two sides ingress of air stream, in the wind-guiding panel that only a side wind-guiding face ingress of air flows, be characterised in that, not only make the bending of wind-guiding face and get involved the direction that air stream changes air stream, and it makes wind-guiding face the direction bending of flowing away from air, and air stream is guided to this direction.
This be because, the wind-guiding face forms concave surface and the continuous and mild smooth surface of convex surface, the section of wind-guiding face length degree direction forms S word shape, thereby can make air stream move and do not get muddled along the wind-guiding surface current.
Preferred in the present invention, housing forms: when the cover plate body of wind-guiding panel and elongated surfaces plate body become the attitude of sealing blow-off outlet under the one state, do not produce the shape in gap between elongated surfaces plate body and housing.Thus, can between elongated surfaces plate body and housing, not accumulate dust, can avoid when the air conditioner entry into service, blowing out the problem of dust.
In order to prevent between elongated surfaces plate body and housing, to accumulate dust, also can form on the housing: when the cover plate body of above-mentioned wind-guiding panel and elongated surfaces plate body become the attitude of sealing blow-off outlet under the one state, the jut in the gap between sealing elongated surfaces plate body and the housing.
In addition, when the cover plate body rotates when becoming the attitude of open blow-off outlet around last axle,, then can the face side to the cover plate body leak cold wind, and make panel body surface or housing cooling from this gap if gapped between cover plate body and housing.Here, if contact with the humid air that contains that is not in harmonious proportion, then can dewfall and become the reason of dirt and breed bacteria.
Therefore, in the present invention, be provided with: the sealing mechanism in the gap when the cover plate body becomes the attitude of open blow-off outlet between seal bootr panel body and the housing.
According to said structure, by sealing mechanism the gap of cover plate body and housing is sealed, can prevent tempered air effectively from this clearance leakage, can dewfall and can be efficiently to required direction blow air.In this structure, under the state of elongated surfaces plate body covering shell, the skin plate body can be closed or open blow-off outlet.
As sealing mechanism, for example between cover plate body and housing, set the seal that both gaps are sealed, then can seal above-mentioned gap all the time.In addition, other form as sealing mechanism, also can be as mentioned above, the cover plate body has the body of the above-mentioned blow-off outlet of sealing and prolongs the sealing of this body, sealing is set to be positioned at across last axle the opposition side of above-mentioned body, be provided with on the housing: when the cover plate body becomes the attitude of open blow-off outlet, and sealing butt and the abutting part in gap between close encapsulation portion and the housing constitutes sealing mechanism by sealing and abutting part.Thus, can reduce the friction of cover plate body in rotating the way as far as possible.
Abutting part can form the rotation track of getting involved sealing, for example forms the abutting part of prominent shape on ora terminalis on the blow-off outlet or following ora terminalis.In addition, also can be above the blow-off outlet of housing, form the slot part that does not hinder sealing to rotate along the housing left and right directions, the lower wall portion of slot part is set at the rotation track of getting involved sealing and butt, and the lower wall portion of slot part is as abutting part.
The preferred axle of going up is set at than the position of blow-off outlet by the top.In said structure, part at the direct butt of sealing on the abutting part can be formed on the face with the blow-off outlet opposition side, can prevent that thus the blast of the tempered air that blows out from blow-off outlet from directly acting on the abutment portion of sealing and abutting part, suppresses the leakage of tempered air more reliably.
In addition, on at least one side of sealing and abutting part, when making the cover plate body become downward attitude, set seal on the part of both contacts,, also can seal the gap between sealing and the abutting part reliably even then on the cover plate body, produce deflection around last axle rotation.Therefore can prevent tempered air effectively from this clearance leakage, thus can dewfall when cooling operation, can be efficiently to required direction blow air.
In addition, make the covering blow-off outlet and can around the structure that lower shaft rotates, can be equipped with the seal that when the wind-guiding panel becomes the attitude of open blow-off outlet around the lower shaft rotation, seals gap between the two at least one side of wind-guiding panel and housing near the following ora terminalis of upwardly extending wind-guiding panel at blow-off outlet from blow-off outlet.Thus, can prevent tempered air, efficiently tempered air be blowed at a distance along the wind-guiding panel from the clearance leakage between wind-guiding panel and the housing.
And,, can at least one side of cover plate body and elongated surfaces plate body, be equipped with the seal in sealing gap between the two constituting under the situation of above-mentioned wind-guiding panel by the cover plate body that covers blow-off outlet and the elongated surfaces plate body of elongation hood panel body.Thus, in that the wind-guiding panel is rotated integratedly towards the place ahead when blow-off outlet blows out tempered air, can tempered air can not blowed to the farther place along the wind-guiding panel from the sealing of cover plate body and the clearance leakage tempered air between the elongated surfaces plate body.
In addition, as wind-guiding panel of the present invention, under the situation of the cover plate body of the size of use switching blow-off outlet, form the cover plate body by mould molding and then be easy to warpage or deflection take place, thereby diminish the outward appearance of air conditioner.Therefore in the present invention, the wind-guiding panel-shaped becomes tabular, and it simultaneously forms the wind-guiding face, in this wind-guiding face side girth member is set.
According to said structure, can suppress the warpage or the deflection of wind-guiding panel by girth member, and girth member can not be exposed to the surface of wind-guiding panel, can keep the air conditioner good surface appearance.Here so-called wind-guiding face is meant on the wind-guiding panel face of air one side that contact blows out from blow-off outlet, the rear side of the wind-guiding panel when promptly becoming the wind-guiding panel and closing the attitude of blow-off outlet.
The wind-guiding panel can be at the back side of tabular exterior trimming parts stacked foaming body layer, in the foaming body layer, be embedded with girth member.According to said structure, the folded foaming body layer on the exterior trimming parts upper strata, and in the foaming body layer, bury girth member underground, can not be the exterior trimming parts surface sweating therefore in the face side of wind-guiding panel.Thereby obtain to take into account the air conditioner of outward appearance and functional requirement.
That is, the foaming body layer that has thermal insulation by formation even blowing out from blow-off outlet under the situation of cold wind, can not make the exterior trimming parts cooling yet and can effectively prevent the generation of dewfall.
In addition, by folded foaming body layer, can make one side side and another side side form difformity on the exterior trimming parts upper strata.Therefore, even paying attention under the situation of framework that aesthetic appearance ground moulding forms panel one side side, also the foaming body layer that is laminated in inner face side can be bent to form and be required wind-guiding shape, thereby can freely set the wind-guiding direction.
To the stacked foaming body layer of exterior trimming parts time, in the mould that is incorporated with exterior trimming parts, inject foaming raw material and form foaming, thereby can obtain to have folded the wind-guiding panel of foaming body layer, but be easy to take place warpage or deflection owing to the material that exterior trimming parts and foaming body layer is different like this is stacked on the exterior trimming parts upper strata.When particularly width was big with respect to length direction on the wind-guiding panel, the central portion of width was easy to take place warpage or deflection largely.
Therefore, to the stacked formation foaming body of exterior trimming parts layer time, the girth member that will have a rigidity is packed into exterior trimming parts in the mould, injecting frothing material forms foaming under this state, thereby can obtain in foaming layer, to be embedded with the wind-guiding panel of girth member, suppress the warpage of wind-guiding panel or deflection and keep aesthetic appearance.
In addition, constitute by the cover plate body that covers blow-off outlet and the elongated surfaces plate body of elongation hood panel body at the wind-guiding panel, cover plate body and elongated surfaces plate body can rotate around above-mentioned lower shaft integratedly, the cover plate body in the top portion around but axle rotates and in the structure of freely openable blow-off outlet ground setting, also can bury girth member underground in the end relative with the elongated surfaces plate body of cover plate body with going up of setting abreast of housing left and right directions.
According to said structure, even producing on elongated surfaces plate body or the cover plate body under the situation of warpage or deflection owing to the on-off action of wind-guiding panel or reason such as aging, also can keep original state as far as possible and keep good surface appearance, and can prevent the clearance leakage of tempered air from elongated surfaces plate body and cover plate body by girth member.In addition, can prevent that also dewfall or air-supply efficient from reducing.
In addition, make the elongated surfaces plate body keep covering the covering attitude of blow-off outlet, and only make the cover plate body when last axle rotation will blow downwards downwards from the air of blow-off outlet, strengthen the end of cover plate body by girth member, thereby can keep the aesthetic appearance of wind-guiding panel.
Promptly, in the time need between elongated surfaces plate body and cover plate body, being provided for making the gap of cover plate body rotation, if the warpage and the bending deformation of the cover plate body of rotating side are big, then this gap must be set at bigger, thereby because the significantly appearance design of reduction wind-guiding panel of the big gap between this elongated surfaces plate body and the cover plate body.
Therefore in the present invention, reinforce by the end relative of girth member as mentioned above, suppress distortion such as warpage on this end or deflection, thereby can reduce the gap between elongated surfaces plate body and the cover plate body with the elongated surfaces plate body to the cover plate body.Thus, can improve visual one sense, obtain air conditioner with good appearance design as the wind-guiding panel.
And, if also be embedded with girth member, then can suppress the warpage or the deflection of elongated surfaces plate body in the end relative of elongated surfaces plate body with the cover plate body, further reduce the gap between elongated surfaces plate body and the cover plate body.
When the cover plate body then need be set at the gap between cover plate body and the elongated surfaces plate body greatly at last shaft position more,, just can reduce the gap between cover plate body and the elongated surfaces plate body effectively by being suitable for the present invention on the cover plate body.
If above-mentioned reason is described in detail, then Figure 14～Figure 16 is for seeing the skeleton diagram of both ends that the cover plate body is relative with the elongated surfaces plate body from the panel side.As shown in figure 14, on cover plate body 8, there is not warpage, under cover plate body 8 and the essentially identical situation of elongated surfaces plate body 9 thickness, for the axis 11a that goes up axle that cover plate body 8 can be formed on the end of cover plate body 8 rotates, need between cover plate body 8 and elongated surfaces plate body 9, have gap X1.
Then, producing on the cover plate body 8 under the situation of deflection D, as shown in figure 15, in order to comprise this deflection D cover plate body 8 can be rotated around the axis 11a of last axle, considering deflection D part and must making the gap enlargement between cover plate body 8 and the elongated surfaces plate body 9 is X2.
But, even under the situation that produces deflection D on the cover plate body 8, as shown in figure 16, if the distance from the ora terminalis of cover plate body 8 to axis 11a is increased to Y2 from Y1, then the gap between cover plate body 8 and the elongated surfaces plate body 9 can be reduced into X3 (wherein, X3＜X2).That is, axis 11a then needs to enlarge the gap between cover plate body 8 and the elongated surfaces plate body 9 more the closer to cover plate body ora terminalis.
As girth member, as long as rigidity is preferably used metal material than the outer plaque or the foaming body floor height that constitute the wind-guiding panel.And, can adopt rotating shaft, L word shape angle steel, U word shape angle steel etc. as girth member.Use under the situation of rotating shaft at girth member,, then needn't establish special-purpose turning cylinder in addition, have the advantage of simplifying the skin plate body structure if rotating shaft is used as above-mentioned turning cylinder as the cover plate body.
The effect of invention
As mentioned above, according to the present invention, but will cover blow-off outlet and near the following ora terminalis of blow-off outlet, rotate and the setting of freely openable blow-off outlet ground around the axis of the lower shaft of setting abreast with the housing left and right directions from the upwardly extending wind-guiding panel of blow-off outlet, form the wind-guiding face of concave curved surface shape in the time of will working as the attitude of the open blow-off outlet of wind-guiding panel rotation becoming continuously with the downside wall of the concave curved surface shape that constitutes the air flow circuit from the fan to the blow-off outlet, on the medial surface of wind-guiding panel, form, thereby can suppress short circuit and tempered air is blowed efficiently at a distance.
