Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail.
First, making a brief description to the technical term related in this detailed description of the invention: following when mentioning front end or the rear end of each structural member, is to define relative to the position of user under structural member normal operating condition; When arrangement position for multiple structural member carries out front or rear description, be also the device that formed with multiple structural member under normal operating condition relative to the definition that the position of user is done.Following heat exchange wind refers to from air-conditioning inside, wind after heat exchanger heat exchange; Non-heat exchange wind refers to the wind from environment space residing for air-conditioning, is for heat exchange wind, is not the part wind directly coming from heat exchanger; Mixing wind refers to the wind that heat exchange wind and non-heat exchange wind are mixed to form.Following ring, referring to the enclosed construction around being formed, being not limited to annulus.
Secondly, briefly explain mentality of designing of the present invention: for the air-conditioner air supply device that heat exchanger of air condition heat exchange wind and outside non-heat exchange wind can be formed mixing wind and sends, the motion of structure to air-flow forming structure, especially its radial section of the annular wind guiding member in heat exchange wind air channel is most important, and then can have influence on the air quantity of the non-heat exchange wind in outside that air-conditioner air supply device sucks and the temperature of mixing wind air-out.So the present invention as research point, seeks the preferred construction that can improve air-conditioner air supply device performance from the structure of annular wind guiding member, especially its radial cross-sectional shape.
Please refer to Fig. 1, this figure is depicted as the structural representation of an air-conditioning embodiment with air-conditioner air supply device 1.
As schematically shown in Figure 1, the air-conditioning of this embodiment includes front panel 2, postnotum 3, Left-Hand Panel, right panel and the top board and base plate (not marking in figure) that form air-conditioner housing, and housing defines the air channel, inside 4 of air-conditioning.Offer mixing wind outlet 21 on the top of front faceplate of air-conditioner 2, export 21 corresponding positions on air-conditioning postnotum 3 top, with the mixing wind on front panel 2 and offer non-heat exchange wind inlet 31.In inner air channel 4, be provided with blower fan 6, heat exchanger 5 and air-conditioner air supply device 1 from bottom to top, and blower fan 6 be arranged so that wind in the inner air channel 4 of air-conditioning is from mixing wind outlet 21 blowout front panel 2.
Wherein, the structure of air-conditioner air supply device 1 please refer to the perspective view of Fig. 2 and the radial section structural representation of Fig. 3.
Anticipate as shown in Figures 2 and 3, simultaneously in conjunction with illustrated in Figure 1, the air-conditioner air supply device 1 of this embodiment includes three annular wind guiding members, is respectively front end annular wind guiding member 11, first intermediate annular wind guiding member 13 and rear end annular wind guiding member 12.Each annular wind guiding member in these three annular wind guiding members that front and back are arranged in order is single component, independent shaping.Wherein, front end annular wind guiding member 11 in the middle of through, there is former and later two openings, open front be air outlet and for mixing wind outlet 111, after-opening is air inlet 112; First through in the middle of intermediate annular wind guiding member 13, there is former and later two openings, be respectively air outlet 131 and air inlet 132; Through in the middle of the annular wind guiding member 12 of rear end, there is former and later two openings, open front is air outlet 121, and after-opening is air inlet and for non-heat exchange wind inlet 122.After being arranged in order before and after the annular wind guiding member 12 of front end annular wind guiding member 11, first intermediate annular wind guiding member 13 and rear end, the middle through air channel (not marking in figure) forming through all three the annular wind guiding members in front and back.And, the first annular heat exchange wind air channel 14 is formed between front end annular wind guiding member 11 and the first intermediate annular wind guiding member 13, be formed with the second annular heat between first intermediate annular wind guiding member 13 and rear end annular wind guiding member 12 and exchange wind air channel 15, the air channel, inside 4 in air-conditioning is connected exchanging wind air channel 15 by the first annular heat exchange wind air channel 14 and the second annular heat with the through air channel in air-conditioner air supply device 1.Wherein, the radial section of each annular wind guiding member in air-conditioner air supply device 1 is curvilinear plane, so that while guiding heat exchange wind smooth flow, improve the flowing velocity as primary airstream, being convenient to the non-heat exchange wind obtained as secondary airflow enters in through-flow air channel, while realizing air-out volume increase, obtain the air-out of proper temperature.And each annular wind guiding member preferably adopts radial section to be incomplete same curvilinear plane, to ensure the uniformity of air-out on the different directions of each heat exchange wind air channel.The concrete structure of the radial section of each annular wind guiding member please refer to shown in Fig. 4 to Fig. 6 and the following description to each figure.
In this embodiment, air-conditioner air supply device 1 is formed by adopting the annular wind guiding member combination of multiple single component form, be convenient to the structure requiring to control flexibly each annular wind guiding member according to air-supply, process each annular wind guiding member that structure is different easily, to ensure uniformity and the air supply velocity of air-supply.And, because each annular wind guiding member is single component, the assembling mode of whole air-conditioner air supply device 1 in air-conditioning can be selected flexibly, and then improve the scope of application of air-conditioner air supply device 1 and the production efficiency of air-conditioning.And, radial section is adopted to be that each annular wind guiding member of curvilinear plane forms heat exchange wind air channel in air-conditioner air supply device 1, not only be beneficial to the circumferential direction air-out of heat exchange wind air channel even, and can effectively lead to heat exchange wind, air-flow is made to realize accelerating while upset, reduce total crushing of air-flow, higher heat exchange wind can be gone out with lower noise water conservancy diversion, improve the wind pushing performance of air-supply arrangement.
