The specific embodiment
Below referring to accompanying drawing, the specific embodiment of the utility model is described.
Referring to figs. 1A to Fig. 4; The utility model provides a kind of air conditioner room unit; Comprise outer casing and be contained in centrifugal fan 8 and the heat exchanger 9 in the outer casing; The air draught side of centrifugal fan 8 is from the air inlet air draught of air conditioner room unit, after the blowing side of centrifugal fan 8 makes wind through heat exchanger 9 heat exchange then, blows out from the air outlet of air conditioner room unit.Obviously, heat exchanger 9 is installed on the blowing side and the inlet air flow path between the front panel 3 of centrifugal fan 8.
According to the embodiment of the utility model, outer casing comprises the top cover 1 and bottom 2 in the face of being provided with each other.This outer casing also comprises the front panel 3 that is connected between top cover 1 and the bottom 2.Top cover 1 all is fan-shaped with bottom 2.Front panel 3 is along the crooked arc of the pairing arcwall face of fan-shaped central angle, and the top of front panel 3 arcwall face corresponding with the fan-shaped central angle of top cover 1 be connected, and the bottom of front panel 3 arcwall face corresponding with the fan-shaped central angle of bottom 2 is connected.
According to the embodiment of the utility model, on top cover 1 or bottom 2, offer air inlet 5 to constitute the air inlet of air conditioner room unit.Shown in Fig. 2 and Fig. 4, air inlet 5 is made up of a plurality of through holes, and these through holes can be evenly distributed on top cover 1 and/or the bottom 2.Shown in Fig. 1 and Fig. 3, offer air outlet 4 on the plate 3 in front, to constitute the air outlet of air conditioner room unit.Air outlet 4 is made up of a plurality of through holes, and these through holes can be evenly distributed on the front panel 3.Wherein the shape of front panel 3 is the arcs towards the indoor set outer projection.When front panel during perpendicular to bottom and top cover, air inlet 5 is in orthogonal direction with air outlet 4, so air intake air-out interference can not occur, can guarantee heating or refrigeration of air conditioner room unit.
Further, with reference to figure 3, Fig. 5 and Fig. 6.According to the embodiment of the utility model, the end face and the bottom surface of front panel 3 laterally arranged.A plurality of through holes of the composition air outlet 4 that distributes on the plate in front can have multiple distribution mode.In the embodiment shown in fig. 3, the through hole that forms air outlet is along extending with the end face of front panel 3 direction vertical with the bottom surface.In the embodiment shown in fig. 5, the through hole that forms air outlet is along extending with the end face of front panel 3 direction parallel with the bottom surface.In the embodiment shown in fig. 6, a plurality of through holes of composition air outlet 4 are scattered in the V font.Different bearing of trends can produce different air supply directions.Different with the even parallel air-supply effect of Fig. 3 and the embodiment shown in Fig. 5, the wind direction that the air outlet 4 that the V font shown in Fig. 6 distributes produces has the disturbance of intersection effect.So can promote circulating of room air more.
According to the embodiment of the utility model, in the through hole of through hole that forms air outlet and formation air inlet, the shape of each through hole also can have different embodiment.For example, shown in Fig. 1, Fig. 3, Fig. 5 and Fig. 6, form air outlet each through hole be shaped as linear, and the through hole of the formation air outlet shown in Fig. 7 to be shaped as wave linear.
When changing shape as the through hole of air outlet, arrangement form (for example Fig. 6 and 7 arrangement form), can finely tune wind direction and blowing range, thereby correspondingly just can omit the labyrinth of rotary type outlet grid.Again for example, for for the through hole of air outlet, the angle that changes the relative side of air vent just can reach certain dustproof effect, improve the air-supply efficient of indoor set.Under the situation for the shape of through holes that constitutes air outlet, arrangement unanimity, the arc front panel has wideer blowing range than the straight front panel of rectangle.
According to an embodiment of the utility model, be arranged to central angle shown in Fig. 1 and Fig. 2 and be 90 ° fan-shaped, and parallel.At this moment, air conditioner room unit is fit to be installed in the rotation angle position of metope 6, and correspondingly also the fan-shaped central angle with top cover 1 and bottom 2 is identical for the angle between two metopes 6.Among this embodiment, the effect that the both walls mask in corner has blocking and reflects wind direction helps to strengthen the air-supply effect of air-conditioner.
According to another embodiment of the utility model, it is 180 ° fan-shaped that top cover 1 and bottom 2 are arranged to central angle shown in Fig. 3 and Fig. 4.At this moment, air conditioner room unit is fit to be installed in the position, plane of metope 6.Have the streamlined of radian because the group of shapes of top cover 1, bottom 2 and front panel 3 is synthetic, make the overall appearance of indoor set that obvious variation compared with prior art take place.Obviously be appreciated that the fan-shaped round angle of top cover 1 and bottom 2 can be all consistent and all less than 90 ℃, also can be all consistent and all greater than 180 ℃ less than 360 °.The streamlined appearance of the outer casing of the utility model, and according to the difference of installation site and the shape of flexible design, can fully satisfy user's individual demand.
In addition, front panel 3 and top cover 1 in the outer casing, and between front panel 3 and the bottom 2, be connected with removably.The mode of removably connecting comprises such as connected modes such as screw connection, buckle connection, plug connections.Like this, can outer casing be disassembled into a plurality of minutes body components, help reducing cost of transportation.
Although above embodiment is to be that example describes with fan-shaped top cover and fan-shaped bottom and arc front panel, this only is an example of the utility model.In fact; Can be to the structure of the top cover of outer casing, bottom, front panel according to carrying out various modification as follows: top cover and bottom all are set to slab construction; The outer peripheral face that this slab construction has upper and lower surfaces and joins with upper and lower surfaces; Outer peripheral face is formed by three faces that head and the tail join successively, and these three faces can be two planes and a smooth surface; Front panel correspondingly can be set to along the crooked twisted plate of this smooth surface; Wherein all radius of curvature of the smooth surface in top cover and the bottom can identical or at least two radius of curvature differences, and the said separately smooth surface of front panel and top cover and bottom interconnects when mounted.In brief, front panel can be various streamlined front panels, and correspondingly the part that cooperates with front panel of bottom and top cover also can be various streamlined curved surfaces.In addition, front panel can be that an entire plate also can be to be spliced by the polylith plate in the utility model, for front panel for for the splice plate that is spliced into by the polylith plate; (the broken line type splice plate is with respect to for the crooked bending plate of smooth surface when splice plate is broken line type; Wherein, be not smooth transition between the two boards that joins in the splice plate), correspondingly; Should be appreciated that the part of joining with front panel of top cover and bottom has and the corresponding to broken line type curved surface of the broken line type of splice plate.
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.
