Therefore, the air conditioner provided by the embodiment of the utility model has the advantages of preventing generation of vortex, enabling the fresh air volume to be larger, reducing the air noise, being excellent in user experience and the like.
In some embodiments of the present invention, as shown in fig. 3, the curved outer side of the longitudinal section of the first arc-shaped portion 210 has an arc-shaped orientation opposite to that of the curved outer side of the longitudinal section of the second arc-shaped portion 220, and the curved inner side of the longitudinal section of the first arc-shaped portion 210 has an arc-shaped orientation identical to that of the curved inner side of the longitudinal section of the second arc-shaped portion 220.
For example, the inner side of the longitudinal section bend of the first arc-shaped part 210 and the outer side of the bend are opposite in direction along the horizontal direction, so that the side of the rain hat 200 adjacent to the air inlet 201 forms a larger air inlet area. The rain hat 200 can collect outdoor fresh air in a wider range, reduces air inlet resistance and improves air inlet volume.
In some embodiments of the present invention, as shown in fig. 1, the flow area of the downward bent portion of rain hat 200 gradually increases from first arc portion 210 to second arc portion 220.
Therefore, the whole rain hat 200 is in a gradually expanding shape, the cross sectional area of the joint of the fresh air pipe 100 is smaller, and the cross sectional area of the air inlet 201 is larger, so that the air flow in the rain hat 200 is smoother, and the generation of vortexes in the rain hat 200 and the fresh air pipe 100 is reduced as much as possible.
In some embodiments of the present invention, as shown in fig. 1, the rain-proof cap 200 further includes a patch 230, one end of the patch 230 is plugged into the fresh air duct 100, and the other end is connected to the first arc 210 of the downward bent portion of the rain-proof cap 200.
For example, the patch 230 and the fresh air duct 100 are fixed by a screw connection, and the cross-sectional area of the patch 230 is the same everywhere along the extending direction thereof. The inner and outer contours of the patch 230 are flush with the inner and outer portions of the first arc 210, and the portion of the patch 230 that connects within the fresh air duct 100 is flush with the edge of the first arc 210. The plug 230 is formed by the rain-proof cap 200, so that the rain-proof cap 200 and the fresh air duct 100 can be firmly fixed.
In some embodiments of the present invention, as shown in fig. 3, the curvature β 2 of the inner side of the bending of the longitudinal section of the first arc-shaped portion 210 and the curvature α 2 of the inner side of the bending of the longitudinal section of the second arc-shaped portion 220 are both less than 160 °, the curvature β 1 of the outer side of the bending of the longitudinal section of the first arc-shaped portion 210 is less than 90 °, and the curvature α 1 of the outer side of the bending of the longitudinal section of the second arc-shaped portion 220 is not more than 90 °.
For example, the curvature of the inner side of the first arc-shaped portion 210 in the longitudinal section is larger than the curvature of the outer side of the first arc-shaped portion 210 in the longitudinal section. The radian of the inner side of the second arc-shaped part 220 in the longitudinal section is larger than the radian of the outer side of the second arc-shaped part 220. By controlling the bending inner side of the longitudinal section of the first arc-shaped part 210 and the arc-shaped radian of the bending outer side of the longitudinal section, the inner side and the outer side of the rain hat 200 which are bent form air guide paths with different radians, the probability of vortex generation is reduced, and the fresh air inlet air quantity is larger.
In some embodiments of the present invention, as shown in fig. 2, the air conditioner further includes a grill 300, and the grill 300 is mounted to an end of the second arc portion 220 away from the first arc portion 210 and covers the intake opening 201.
The grille 300 can prevent branches, insects, birds and the like from entering the interior of the rain hat 200 or the fresh air duct 100 by mistake. The shape of the grill 300 is adapted to the shape of the second arc part 220, for example, the grill 300 forms a circular structure, thereby facilitating the assembly of the grill 300 with the rain hat 200.
Further, as shown in fig. 2, the grill 300 includes a plurality of surrounding ribs 310 and a plurality of connecting ribs 320.
The surrounding ribs 310 are sleeved from outside to inside along the radial direction of the air inlet 201, and the surrounding rib 310 located at the outermost side is connected to the second arc-shaped portion 220. Adjacent two of the circumferential ribs 310 are connected by a plurality of connecting ribs 320 provided at intervals in the circumferential direction of the grill 300.
The outermost circumferential rib 310 conforms to the contour of the end of the second arcuate portion 220 to allow the grill 300 to be assembled with the rain hat 200. A plurality of wind-guiding passageways that form air intake 201 between the muscle 310 of encircleing to will encircle the muscle 310 through splice bar 320 and connect into overall structure, a plurality of muscle 310 and a plurality of splice bar 320 of encircleing all cover air intake 201, encircle muscle 310 and set up with splice bar 320 is perpendicular, form network structure, avoid the foreign matter to get into rain-proof cap 200 or new tuber pipe 100.
Further, as shown in fig. 2, the width of each of the connecting rib 320 and the surrounding rib 310 is not greater than 2.5 mm.
Therefore, the width of the connecting rib 320 and the width of the surrounding rib 310 are both moderate, foreign matters can be prevented from entering the interior of the rain hat 200 or the fresh air duct 100, the area of the air inlet 201 cannot be covered by the connecting rib is too large, and fresh air can be smoothly guided into the connecting rib.
In some embodiments of the present invention, as shown in fig. 1 and 3, the central axis of the fresh air duct 100 is perpendicular to the central axis of the intake vent 201.
For example, the fresh air duct 100 extends horizontally, and the air inlet 201 faces downward. So, and rain-proof cap 200 can form comparatively moderate angle of buckling, has satisfied smooth-going air inlet effect and good rain-proof effect simultaneously.
In some embodiments of the present invention, the flow area of the inlet 201 is not smaller than the flow area of the fresh air duct 100. The air inlet area of the air inlet 201 is large, so that the flow of fresh air in the interior of the rain hat 200 can be ensured, and the generation of vortex can be avoided.
Other configurations and operations of the air conditioner according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
