Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not constitute improper restriction of the present invention.In the accompanying drawings:
Fig. 1 shows the schematic top plan view according to the embodiment of air-conditioner of the present invention, wherein only shows the structure of spiral case and through-flow fan blade among the figure;
Fig. 2 shows the right view of the air-conditioner of Fig. 1; And
Fig. 3 shows the three-dimensional structure diagram of air-conditioner embodiment of the present invention.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Through after a series of experimental verification, find evaporimeter its fin blocks of being superimposed from left to right in reality processing, compress from top to bottom from the right side, this just causes the fin gap in evaporimeter left side (wearing U pipe side) can be littler than gap, right side (eyesight elbow connection side) again.The size that one skilled in the art will appreciate that the gap influences intake, and the big air intake in gap is many, and the little air intake in gap is few.Thereby cause the evaporimeter right-hand member intake can be bigger than left end, evaporimeter left and right sides two ends heat exchange effect be unequal, can not give full play to evaporimeter heat exchange effect, influences performance boost.Simultaneously, this can cause two ends, the inner left and right sides, air channel the temperature difference to occur, thereby causes the condensation weak effect; And because two ends, left and right sides intake is unequal, cause in the air channel two ends, left and right sides air-flow pressure and eddy current inconsistent, and causing the overall noise weak effect, this is to cause one of bigger reason of the noise of air-conditioner.
As shown in Figure 1 to Figure 3, the air-conditioner of present embodiment comprises evaporimeter, spiral case and is arranged on spiral case inner and be positioned at the through-flow fan blade 1 of evaporimeter below, spiral case comprises: first spiral case 10 and second spiral case 20, first spiral case 10 is arranged on a side of through-flow fan blade 1 and extends along the axis direction of through-flow fan blade 1, and first spiral case 10 forms the first snail tongue 11 towards the end of through-flow fan blade 1 air inlet; Second spiral case 20 is arranged on the opposite side of through-flow fan blade 1 and extends along the axis direction of through-flow fan blade 1, and second spiral case 20 forms the second snail tongue 21 towards the end of through-flow fan blade 1 air inlet.Gap between the fin of the evaporimeter of the air-conditioner of present embodiment reduces to the direction along second end of axis direction along first end of axis direction gradually along air-conditioner, and the gap between the first snail tongue 11 and the second snail tongue 21 and the through-flow fan blade 1 all direction from first end of air-conditioner to second end correspondingly reduces gradually.As depicted in figs. 1 and 2, the gap between the first snail tongue 11 and the through-flow fan blade 1 is gradient to maximal clearance B from minimum clearance A, and the second snail tongue 21 is gradient to maximal clearance D with the gap of through-flow fan blade 1 from minimum clearance C.
Those skilled in the art can know, as possible implementation, also can only make between the first snail tongue 11 and the through-flow fan blade 1 the gap all first end from air-conditioner along axis direction correspondingly reduce gradually to the direction along second end of axis direction, or only make between the second snail tongue 21 and the through-flow fan blade 1 the gap all the direction from air-conditioner first end to second end correspondingly reduce gradually.
Evaporimeter its fin blocks of being superimposed from left to right in reality processing generally speaking, in the present embodiment, the left end of air-conditioner be air-conditioner along first end of axis direction, the right-hand member of air-conditioner is second end of air-conditioner.
Preferably, the minimum clearance between the first snail tongue 11 and the second snail tongue 21 and the through-flow fan blade 1 is all in 2 to 8mm scope.Maximal clearance between the first snail tongue 11 and the second snail tongue 21 and the through-flow fan blade 1 is all in 3 to 15mm scope.In the present embodiment, minimum clearance is the first snail tongue 11 of air-conditioner first end and the gap between the through-flow fan blade 1, and the maximal clearance is the second snail tongue 21 of air-conditioner second end and the gap between the through-flow fan blade 1.
Experimentize according to present embodiment, with air-conditioner contrast noise, crest frequency and the air quantity of prior art, test as follows:
Test condition: sound pick-up is positioned over 1m place before the outer machine, and sound pick-up is apart from ground level 1m; The test operating mode: under the voltage stabilizing electrical testing condition, air-conditioning is opened air supply pattern; Under above-mentioned test condition, the working condition air-conditioning is moved 40 minutes respectively under low windscreen refrigeration mode, middle windscreen refrigeration mode, high windscreen refrigeration mode, measuring this experiment correction data.L is that air-conditioning is in when hanging down the windscreen refrigeration mode; M is during air-conditioning is in during the windscreen refrigeration mode; H is that air-conditioning is when being in high windscreen refrigeration mode; SH is air-conditioning when being in superelevation windscreen refrigeration mode, and data are overall noise value, peak value and frequency value corresponding thereof and air-out value in the table.
Phenomenon is experienced in test: when on-the-spot experience air-out is unstable, the test function of assembling prior art is heard the abnormal sound sound that the air-out inequality causes more significantly, and the testing machine abnormal sound sound of embodiments of the invention has bigger improvement, and one meter distance of distance test (DT) machine is not heard abnormal sound.
Concrete test data is as follows:
(1) low wind shelves:
(2) apoplexy shelves:
(3) high wind shelves:
(4) superelevation wind shelves:
By experiment as can be known, the air-conditioner of present embodiment air-conditioner noise more of the prior art is low, and acoustical quality is also better.Since adopted said structure, an end of evaporator fin gap minimum, the gap of the first and second snail tongues and through-flow fan blade (gap A and clearance C) minimum, air-flow was more anxious when air-flow entered air-conditioner, had improved the intake of this end; One end of evaporator fin gap maximum, the first and second snail tongues with through-flow fan blade gap (gap B and clearance D) maximum, air-flow relaxed when air-flow entered air-conditioner, reduced the intake of this end, finally reach whole air channel air-flow pressure unanimity, the purpose of whole evaporimeter intake unanimity, final realization promotes evaporimeter heat exchange effect effectively, greatly improve the condensation effect, reached simultaneously and reduced the noise of air-conditioner and the design object of improving the tonequality of air-conditioner.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
