Detailed description of the invention
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.It should be noted that when not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
As shown in Figures 1 to 5, in Fig. 3, the direction of arrow shown in solid is air intake direction, the direction of arrow shown in dotted line is air-out direction, and according to embodiments of the invention, air conditioner room unit includes housing 10, flow-guiding structure 20, through-flow fan blade 30, heat exchanger 40 and control portion 70.Its middle shell 10, flow-guiding structure 20, through-flow fan blade 30, heat exchanger 40 and control portion 70 are arranged in the cavity within housing 10.
Housing 10 includes front panel 14, rear board 15 and two side panels being connected between front panel 14 and rear board 15.Front panel 14 and rear board 15 are arcuate structure outwardly, and two side panels are the arcuate structure of the indent being correspondingly arranged, and form cavity between front panel 14, rear board 15 and two side panels.Air inlet 11 is arranged on rear board 15, and air outlet 12 is arranged on front panel 14, and air inlet 11 is arranged accordingly with air outlet 12.Housing 10 can provide for the miscellaneous part of air conditioner room unit and install matrix, it is ensured that the globality of air conditioner room unit outward appearance.
In order to expand the wind-out range at air outlet 12 place, air outlet 12 place is provided with rotating wind blade 13, thus air-out is carried out water conservancy diversion, it is possible to the flow direction needing control air outlet 12 place air-flow according to people.
Through-flow fan blade 30 in the internal cavities of housing 10 rotatably arranged with, the rotating shaft of through-flow fan blade 30 is obliquely installed relative to the cross section of housing 10, it is possible to reduces the space within housing 10 that takies, and then reduces the volume of housing 10.Preferably, the angle between rotating shaft and the cross section of housing 10 of through-flow fan blade 30 is 30 ° to 60 °, it is preferable that the angle between rotating shaft and the cross section of housing 10 of through-flow fan blade 30 is 45 °.
Because through-flow fan blade 30 is the power source of air current flow, so for the air draught ability strengthening air inlet 11 place, through-flow fan blade 30 being tilted towards the direction of the air inlet 11 of housing 10.
Flow-guiding structure 20 is for guiding the air-flow at air inlet 11 place to air outlet 12 place.Flow-guiding structure 20 includes the first guide face 21 and the second guide face 22 positioned opposite, form one end between first guide face 21 and the second guide face 22 and extend to heat exchanger 40, the other end extends to the flow-guiding channel at air outlet 12 place, through-flow fan blade 30 is arranged in flow-guiding channel, make the air-flow driven by through-flow fan blade 30 can flow to air outlet 12 place along flow-guiding channel, make air flow direction more stable, it is prevented that sinuous flow occurs.
Because through-flow fan blade 30 is around own axis, the air-flow flowing through through-flow fan blade 30 can be advanced along the periphery of through-flow fan blade 30.In order to comply with the flow trace of air-flow, the first guide face 21 and the second guide face 22 are arcuate structure, and wherein the first guide face 21 is the first arcuate structure that the periphery with through-flow fan blade 30 adapts, this first arcuate structure convex surface facing through-flow fan blade 30；Second guide face 22 is the second arcuate structure that the periphery with through-flow fan blade 30 adapts, and the concave surface of the second arcuate structure is towards through-flow fan blade 30.
Flow-guiding structure 20 also includes fixing, with two opposite edges of the first guide face 21 and the second guide face 22, the 3rd guide face 23 and the 4th guide face 24 being connected respectively.Flow-guiding channel is closed diversion space that form two opposite sides opening, that include flow-guiding channel by first guide face the 21, second guide face the 22, the 3rd guide face 23 and the 4th guide face 24.Flow-guiding structure 20 is obliquely installed accordingly with through-flow fan blade 30, it is possible to play the effect of water conservancy diversion better, and the flow-guiding structure 20 simultaneously tilted can also make full use of housing 10 inner space, reduces the volume of housing 10 further.
Heat exchanger 40 and through-flow fan blade 30 set gradually along air intake to the direction of air-out.The gas flow temperature by heat exchanger 40 can be changed, it is achieved the function freezed or heat.In the present embodiment, heat exchanger 40 is the v-shaped structure including adjacent first paragraph and second segment, and the concave surface of v-shaped structure is towards through-flow fan blade 30, and the angle between the first paragraph of v-shaped structure and second segment is 90 °.Owing to heat exchanger 40 is positioned at one end of flow-guiding channel, so the air-flow in order to flow through heat exchanger 40 enters flow-guiding channel better, heat exchanger 40 is obliquely installed accordingly with through-flow fan blade 30.Being additionally provided with drip tray 80 bottom heat exchanger 40, the shape of drip tray 80 is corresponding with the v-shaped structure of heat exchanger 40.
Here the angle between the v-shaped structure two opposite side walls of heat exchanger 40 is not limited to 90 °, it should arrange according to actual needs.Heat exchanger 40 is also not necessarily limited to v-shaped structure, and can be arcuate structure.
