The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The side cross-sectional schematic of first embodiment of the air-conditioner of air-out up and down of the utility model has been shown among Fig. 2.The air-conditioner of air-out up and down of the utility model comprises: be separately positioned on last cross flow fan 3 and following cross flow fan 4 in the air-conditioner up and down, the last drain pan 2 and the following drain pan 5 that are connected with air-conditioner backboard 1 respectively; Respectively around upper and lower cross flow fan; Last drain pan 2 tops have last air outlet 6, and following drain pan 5 bottoms have following air outlet 7, and upper and lower drain pan connects through dividing plate 9; Evaporimeter 8 is arranged between upper and lower cross flow fan and the air inlet 10.Simultaneously, mark the direction of air-flow among the figure with arrow.
Preferably, to the diameter Relationship of fan blade up and down, following cross flow fan 4 diameters are more than or equal to last cross flow fan 3, and the air quantity of going up air outlet 6 when guaranteeing refrigeration is too not little, consider simultaneously to improve to heat that air outlet 7 air quantity are suitable at present.Like Fig. 4 and shown in Figure 5, air quantity has been shown with the chart of upper and lower cross flow fan diameter among Fig. 4 than variation, noise has been shown with the chart of upper and lower cross flow fan diameter among Fig. 5 than variation.According to researching and analysing, diameter is than changing greatly greater than air quantity, noiseproof feature after 3, and therefore the fan blade diameter Relationship is designed to down the diameter=1-3 of diameter/upward up and down.Thus, the diameter that descends cross flow fan 4 is designed to greater than last cross flow fan 3, thereby strengthens the air quantity of air outlet 7 down, realize that more hot blast directly blows to ground, increase human comfort.Last air outlet 6 air quantity are less, reduced the collision loss of last air outlet 6 and top wall.
Referring to Fig. 4 and Fig. 5, when the diameter ratio of upper and lower cross flow fan surpassed 2, air quantity and noise all began fast rise, and when arriving 3, the ratio that air quantity improves begins to slow down, and the noise increase reaches about 3 decibels.Therefore, the diameter ratio of upper and lower cross flow fan is designed to 1 to 3, to reach better technical effect.
Preferably, upper and lower two air outlets air-out simultaneously.To the angular relationship between last air outlet 6 and the following air outlet 7; Last air outlet 6 and horizontal sextant angle are less than following air outlet 7 and horizontal sextant angle; Angular range between two air outlets is between 60 °～180 °, and two through-flow fan blade diameter proportions are big more, and angle is more little between two air outlets.According to the cross flow fan specificity analysis, the machine air output was big more in angle was more little, so the fan blade diameter need be designed to corresponding proportion.As shown in Figure 6, the air output of the air-conditioner of air-out up and down that the utility model has been shown among Fig. 6 is with the chart of upper and lower air outlet 7 with air inlet 10 variable angle.
Referring to Fig. 6, the air quantity peak value that changes with the angle of last air outlet and air inlet appears at about 20 degree, and with the air quantity peak value that the angle of air outlet down and air inlet changes appear at 45 spend about.It is a preferred embodiment here.Simultaneously; As confirming of number range, when the angle of last air outlet and air inlet less than 20 degree or greater than 80 degree, when the angle of following air outlet and air inlet is spent less than 40 or spent greater than 100; Air quantity all sharply descends; Therefore, the setting of air-out angle should not exceed this scope, and the angle of just controlling both is between 60 degree to 180 degree.
Preferably, to the structure of drain pan, two through-flow fan blades are through the separately control of two motors; A two shared cover drain pan assembly and evaporimeter 8 assemblies of blower fan system, this drain pan assembly comprises drain pan 2 and following drain pan 5, upper and lower drain pan is designed to different because of the through-flow fan blade selection is different; Connect through central dividing plate 9 between upper and lower drain pan, dividing plate 9 blower fan system flow passage structure up and down separates, when two drain pan structures are identical; Dividing plate 9 is designed to 0 ° with horizontal sextant angle, makes the air output balance.For reducing the airflow reflux in air intake zone; Improve air output, along with cross flow fan 4 and the increasing of last cross flow fan 3 diameter proportions down, dividing plate 9 strengthens with horizontal sextant angle; Giving bigger cross flow fan with enough intakes, 0 °～+ 10 ° of the scopes of dividing plate 9 placement directions and horizontal sextant angle.Consider from production technology design and installation convenience, with the minimum range >=5mm between dividing plate 9 tops and the evaporimeter 8.Distance is too little to bump easily, so be controlled at beyond the certain distance.
Preferably; Structure to evaporimeter 8; Evaporimeter 8 assembly profiles can be designed to multi-fold structure or arc structure in the utility model, can increase air-flow multi-angle airintake direction, improve through-flow fan blade intake velocity distributing homogeneity; Reduce inlet vane flow separation noise simultaneously, improve the heat exchange property of cross flow fan system effectiveness and evaporimeter 8; Evaporimeter 8 assemblies adopt the design of two rows or three row's monolithic constructions, are positioned over two cross flow fan system front sides, improve the machine system exchange capability of heat, and evaporimeter 8 assembly installed in front have screen pack and air-inlet grille.
As shown in Figure 2, among first embodiment, two through-flow fan blade external diameters are identical up and down; The structure of two blower fan systems is symmetrical basically up and down, central dividing plate 9 horizontal positioned, and evaporimeter 8 is designed to arc structure three row's symmetries and places; Upper and lower two air outlets are identical with horizontal air intake angular separation; The air outlet angle is approximately 90 degree up and down, makes that the air quantity of air outlet is basic identical up and down, the mutual portfolio effect of cooling and warming.
As shown in Figure 3, among second embodiment, two cross flow fan diameters are unequal up and down; Following diameter/go up diameter=1.3, evaporimeter 8 is designed to multi-fold structure, and per two roll over each other angle＞90 °; Be designed to three dischargings at last cross flow fan 3 air intake regional evapotranspiration devices 8 and put, central dividing plate 9 tops are near the junction of last two foldings with following three foldings, and last air outlet 6 is 30 ° with the angle of air inlet 10; Last air outlet 6 air quantity are less, and are less with the angle of air intake direction, reduced the collision loss of last air outlet 6 and top wall; Angle is 65 ° between following air outlet 7 and the air inlet 10, and following cross flow fan 4 diameters are bigger, makes that air outlet 7 air quantity strengthen down; Air outlet and air inlet 10 angles are bigger simultaneously, and more hot blast directly blows to ground in the time of can realizing heating, and increase human comfort.
The air-conditioner of air-out up and down according to the utility model has following beneficial effect:
Adopt upper and lower two through-flow fan blade systems, can improve the air quantity effect of indoor set; Following air outlet air quantity is bigger than last air outlet, and hot blast blows downwards, and the human feeling is more comfortable.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
