Abstract
The utility model discloses a volute and an air hose unit. The volute comprises an upper volute. The upper volute comprises a cambered upper shell and a straight-face upper shell connected with the top end of the cambered upper shell. The angle formed between the bottom face of the straight-face upper shell and the tangent plane of the top end of the cambered upper shell is larger than 0 degree and smaller than or equal to 45 degrees. According to the technical scheme, because the bottom face of the straight-face upper shell inclines relative to the tangent plane of the top end of the cambered upper shell, airflow can be distributed in an air conditioner more evenly, and turbulent flow areas are effectively prevented; therefore, the amount of circulating air per unit time is effectively increased; in addition, operating noise of an air conditioner internal unit can be effectively lowered.

Wherein, described angle is greater than zero degree and is not more than 10 degree.
Wherein, the angle ranging from 5 degree.
Wherein, the described upper casing of facing directly becomes plate.
Wherein, the described upper casing wedgewise of facing directly.
Wherein, face the end face of upper casing directly parallel with the tangent plane on curved surface upper casing top.
A kind of wind pipe machine, comprise above-mentioned spiral case, also comprises according to the heat exchanger set gradually to the exhaust outlet direction from exhaust port, wind deflector and water receiving disc, and it is trapezoidal that described wind deflector roughly is.
A kind of wind pipe machine, comprise more than one spiral case, and at least one spiral case is above-mentioned spiral case.
The beneficial effects of the utility model are: a kind of spiral case, comprise upper volute, described upper volute comprise the curved surface upper casing, with curved surface upper casing top, be connected face upper casing directly, face the bottom surface of upper casing and the tangent plane angulation on curved surface upper casing top directly and be greater than zero degree and be not more than 45 degree.The bottom surface of facing upper casing directly of the technical program spiral case tilts with respect to the tangent plane on curved surface upper casing top, can make air-flow distribute more evenly in air conditioner inside, effectively contained the generation in sinuous flow zone, thereby make the air circulation in the unit time effectively be promoted, moreover, can also effectively reduce the running noise of air-conditioning internal machine.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the utility model, but not to restriction of the present utility model.It also should be noted that, for convenience of description, only show the part relevant to the utility model in accompanying drawing but not entire infrastructure.
As shown in Figure 1, be the sectional drawing of wind pipe machine of the present utility model.A kind of spiral case, comprise upper volute 2.This upper volute comprise curved surface upper casing 23, with curved surface upper casing top 231, be connected face upper casing 21 directly, the bottom surface 212 of facing upper casing directly is greater than zero degree and is not more than 45 degree with the angle that the tangent plane on curved surface upper casing top 231 is.
In this example, spiral case is comprised of upper volute 2 and lower spiral case 7.Upper volute 2 is divided into two sections, and one section is crooked part, is curved surface upper casing 23, and the other end is the straight part be connected with curved surface upper casing 23, is and faces upper casing 21 directly, and upper volute is integrated.The bottom surface 212 of facing upper casing directly is preferably more than 0 degree and is less than 10 degree with the angle that the tangent plane on curved surface upper casing top 231 is, such as can be 1 degree, 2 degree, 5 degree, 9 degree, 10 degree etc., more preferably 5 degree.This angle is crossed conference and is produced excessive upper casing 21 and the uneven slip of curved surface upper casing 23 in the transition be connected on curved surface upper casing top 231 faced directly, thereby be with, serves disorderly air-flow, affects the effect of air quantity and noise reduction.
It is in a preferred embodiment, described that to face 21 one-tenth of upper casings directly plate.
In another preferred embodiment, described upper casing 21 wedgewises of facing directly, the end face 211 of facing upper casing directly can be parallel with the tangent plane on curved surface upper casing top 231.Part in the middle of wedge shape can be solid, also can be hollow.
This wind pipe machine comprises casing 1 and is arranged at least two spiral cases 2 in this casing 1.These spiral case 2 inside arrange centrifugal blower 3, are provided with exhaust port 22 on spiral case 2.Also be provided with heat exchanger 5, wind deflector 4 and water receiving disc 6 in casing 1, be provided with an exhaust outlet 11 and at least one intake grill on casing 1.Spiral case 2, intake grill are arranged on an end face of casing 1, and heat exchanger 5, wind deflector 4 and water receiving disc 6, exhaust outlet 11 are arranged on the other end of casing 1.This heat exchanger 5, wind deflector 4, water receiving disc 6 are arranged between this exhaust port 22 and exhaust outlet 11, according to from exhaust port 22 to exhaust outlet 11 direction arrange successively.The air stream formed after the disturbance of the air that centrifugal blower 3 enters intake grill by centrifugal action, discharged and blown on heat exchanger 5 by exhaust port 22, and the wind after heat exchanger 5 carries out heat exchange is sent by exhaust outlet 11 under the guiding of wind deflector 4.Wind deflector 4 is trapezoidal, is expandable plastic.Water receiving disc 6 is expandable plastic, the major function of water receiving disc 6 be collect on condenser, flow down condensed water, and discharge wind pipe machine by the mode of water pump or gravity flow (Water seeks its own level).Under under the prerequisite that does not affect water receiving disc 6 drainings, wind deflector 4 can be the integrated design with water receiving disc 6.
It should be noted that as a kind of mode of execution, can, by spiral case 2 to the certain angle of casing 1 inner inclination, make the top board of facing upper casing 21 and casing 1 directly of spiral case 2 be certain angle of inclination.
Above embodiment can make air-flow distribute more evenly in air conditioner inside, effectively contained the generation in sinuous flow zone, thereby make the air circulation in the unit time effectively be promoted, air stream can blow on heat exchanger 5 more uniformly and effectively, improves the heat transfer effect of heat exchanger 5.Can effectively reduce exactly in addition the running noise of air-conditioning internal machine, because air quantity gets a promotion, motor just can be with lower rotation speed operation, thereby running noise can effectively be reduced.
Note, abovely described in conjunction with specific embodiments know-why of the present utility model.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, within these modes all will fall into protection domain of the present utility model.
