Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.
This embodiment provides an air duct structure for push out wind formula mobile air conditioner, this air duct structure places the air outlet in the position placed in the middle, and wind gets into the wind channel from wind channel both sides and increases the air inlet area, blows off from the top, and the air-out is partial to the organism openly. The bottom in the air duct is provided with a water guide hole to prevent the condensed water from blowing out. The following detailed description will proceed with reference being made to specific embodiments.
Example one
Fig. 1 schematically shows a structural view of an air duct structure provided in this embodiment, and fig. 2 schematically shows a front view of the air duct structure provided in this embodiment. As shown in fig. 1 and 2, the air duct structure may include, for example, a base 1 and a centrifugal air duct 2.
One end of the centrifugal air duct 2 is connected with the base 1, and the other end opposite to the end is provided with an air outlet 21, after the centrifugal air duct structure is installed on the top wind type mobile air conditioner, the air outlet 21 is located in the middle of an air outlet panel of the top wind type mobile air conditioner, namely, the air outlet 21 is located in the center of the whole body. The design can ensure that the wind fields at the two sides of the whole machine are symmetrically distributed theoretically, so that the wind outlet fields are uniform.
In a feasible manner of this embodiment, the base 1 and the centrifugal duct 2 may be an assembly structure formed in one step, and the one-step forming includes integrally forming or completing a plurality of components assembled together in one step in a mold. The base 1 and the centrifugal air duct 2 may be formed separately and then connected together by means of snap-fit or screw fixation. The specific selection can be determined according to actual requirements. The preferred integrated configuration of once forming of this embodiment, the design makes and just can process this wind channel structure through a mould like this, has improved machining efficiency.
One side of base 1 adds the back, and the air-out direction of air outlet 21 is the acute angle with the planar contained angle of air-out side panel, as the direction shown in fig. 1, base 1 left side thickening promptly. The mode of thickening can be as shown in figure 1 from base 1 right side to the left thickness of base 1 increases in succession, and the bottom surface of base is the plane after the thickening, and this kind of thickening mode makes wind channel structure install behind the space that each panel of head-wind formula mobile air conditioner enclosed, and the area of stress of its base is big, and is fixed stable. The mode of thickening also can be only thickening 1 left sides of base (the direction shown in figure 1), only increase the gasket of predetermineeing thickness in base 1 left side equivalently, with bed hedgehopping base 1 left side, some actual demands can be satisfied to this kind of mode, for example, the position at the mobile air conditioner installation base of headwind formula, it is equipped with other protruding structures to correspond the base middle part on the air conditioner, if adopt above-mentioned first kind of thickening mode, the intermediate position of base probably takes place to interfere with protruding structure after the thickening, influence the installation of base, therefore, select the second kind of thickening mode more to be fit for. Concrete thickening mode the utility model discloses do not do the restriction, concrete thickening mode can be according to actual demand and decide. The design mode of the base enables air outlet to be deviated to the front direction of the machine body, the wind direction does not need to be changed through the wind deflector, kinetic energy loss of wind is reduced, and air supply distance is increased.
The thickness of one side thickening of base 1 can not too big, also can not undersize. The thickness is too small, although the air outlet direction is not upward in the front in the traditional scheme any more, the air outlet direction is deviated to the front of the machine body, the air guide plate has a certain length, partial air can still need to change the air direction by the air guide plate, and the air outlet direction is not the optimal direction. The thickness is too big, though the air-out does not need the aviation baffle to change the wind direction completely, nevertheless because the base gradient is too big, the contained angle between air-out direction and the air conditioner air-out side plane is too little, and wind probably is sheltered from by other parts of air conditioner, also is unfavorable for the air-out. Through the research of this embodiment, 1 one side thickening back of base, the value range of the acute angle (the contained angle of line and the horizontal plane of thickening one end and the non-thickening one end in the direction shown in figure 1) that air-out direction and air-out side panel plane pressed from both sides is 5 ~ 10 degrees, and this scope is applicable to the top wind formula mobile air conditioner of most models. This embodiment is preferably 7 degrees. The specific thickness of thickening is decided according to the actual demand, the utility model discloses do not do the restriction.
In a feasible mode of the embodiment, based on the fluid mechanics principle, the air outlet 21 is designed to be a rectangular air outlet, and the air outlet is flat, so that the air speed is larger during air outlet, and the air outlet distance is larger.
In summary, in the embodiment, the air outlet of the centrifugal air duct is arranged in the center of the panel on the air outlet side of the top-outlet type mobile air conditioner, so that the air fields on the left side and the right side of the whole machine are theoretically and symmetrically distributed, and the problem of uneven air outlet field on the top-outlet type mobile air conditioner is solved. And one side of the air duct structure base is thickened, so that the branch deviates to the front direction of the machine body, the wind direction does not need to be changed through the wind deflector, the kinetic energy loss of wind is reduced, and the air supply distance is increased.
Example two
Referring to fig. 1 and 2, the air duct structure in the present embodiment includes air inlets 22 disposed at the front and rear sides (the direction shown in fig. 1 and 2) of the centrifugal air duct 2, in addition to the air duct structure described in the first embodiment. The design enables wind to enter the air channel from two sides of the air channel, the air inlet area of the air channel is increased, the wind speed is reduced, and therefore noise is reduced. In a feasible manner of this embodiment, the air inlet 22 is designed as a circular air inlet, and from the fluid mechanics perspective, the circular air inlet has a smooth profile and no obvious edge angle, so that the air duct can supply air more smoothly.
A water guide hole 23 (a lower end in the direction shown in fig. 1 or 2) is further provided in the centrifugal duct 2 at a position close to the base 1. Even if the air conditioner works under the high-humidity working condition, the water guide holes 23 can guide out the condensed water generated in the air duct through the water guide holes, and the condensed water is prevented from being blown out.
In order to optimize the water guiding effect of the water guiding hole 23, a water inlet (shown as a in fig. 1) of the water guiding hole 23 is arranged at the middle position of the portion, close to the base 1, in the centrifugal air duct 2, and an outlet (shown as B in fig. 1) of the water guiding hole 23 is arranged at the lower side of the air inlet 22 at the two sides of the centrifugal air duct 2. The design can lead the formed condensed water through water guide hole 23 in the air duct to the base 1, and the condensed water is prevented from accumulating on the inner side of the air duct.
Further, as shown in fig. 3, the water guiding hole 23 is disposed in an inclined manner with respect to the horizontal plane, specifically, the height of the water inlet a perpendicular to the horizontal plane is greater than the height of the water outlet B perpendicular to the horizontal plane, so that the condensed water can be ensured to smoothly flow out from the water guiding hole 23. The water guide hole 23 is not inclined at an excessively large angle or at an excessively small angle with respect to the horizontal plane (the direction shown in fig. 1). The water inlet A and the water outlet B are basically in the same horizontal plane when the inclination angle is too small, and the water guide effect of the water guide hole 23 is possibly poor due to vibration generated in the working process of the air conditioner. Inclination is too big, if the air conditioner work leads to the inboard more comdenstion water that produces of wind channel under the high wet operating mode, because water inlet A and delivery port B difference in height are great, because the action of gravity, the velocity of flow of comdenstion water in water guiding hole 23 is great, and the impulsive force is great, probably makes the comdenstion water can not follow wind channel lateral wall smoothly and flows to base 1 on, the comdenstion water can sputter other parts of air conditioner, damages air conditioner part. In a feasible manner of the present embodiment, the water guide hole 23 is inclined to the horizontal plane within an angle range of 3 to 7 degrees, which not only has a good water guide effect, but also does not allow the condensed water to splash to other parts of the air conditioner due to an excessive flow velocity. Furthermore, a water receiving groove can be arranged on the air conditioner base 1 to prevent the condensed water from flowing to other parts of the air conditioner.
In a feasible mode of this embodiment, the cross section of the water guide hole 23 is circular, and based on the theory of hydrodynamics, the water guide hole with a circular cross section has a smooth profile, no obvious edge angle and a low adhesion effect to water, so that no accumulated water is present in the water guide hole 23, and a good water guide effect is achieved.
In conclusion, the air inlets are formed in the two sides of the centrifugal air duct of the air duct structure, air can enter the air duct from the two sides of the air duct, the air inlet area of the air duct is increased, the air speed is reduced, and therefore noise is reduced. And the part close to the base in the centrifugal air duct is provided with the water guide hole, so that even if the air conditioner works under a high-humidity working condition, the condensed water generated in the air duct can be guided out through the water guide hole, and the condensed water is prevented from being blown out.
It should be understood that the above-mentioned embodiments are all based on the directions shown in the drawings, and are not intended to limit the present invention.
