Detailed Description

The present invention is further described below in conjunction with the following figures and examples, it being understood that the following examples are intended to illustrate and not to limit the present invention.

1. Example one

An outlet according to the invention is shown in figure 1. The air outlet 1 includes an upper casing 21, a lower casing 22, an air guide block 3, and an air guide blade group 4. After the upper shell 21 and the lower shell 22 are combined, two sides are provided with elongated rectangular gaps, one side is an air inlet side 23, and the other side is an air outlet side 24. The air guide block 3 and the air guide blade group 4 are assembled in the shell, and the air guide block 3 divides the cavity of the shell into an upper part and a lower part. When the air guide block 3 moves up and down, the proportion of the upper part and the lower part of the cavity of the shell can be changed.

As shown in fig. 2, the air guide block 3 has a well 31 extending along the outline of the air guide blade, and the air guide blade group 4 penetrates the well 31. The open side of the well 31 comprises a plurality of continuous curved surfaces 32, and the shape of the curved surfaces 32 is substantially consistent with the shape of the motion envelope surface of the blade as the well is arranged to avoid the motion envelope surface of the blade. The number of the curved surfaces is consistent with that of the air guide blades, and two ends of each curved surface correspond to the limit rotating positions of each air guide blade.

As shown in fig. 3 and 4, the blades of the air guide blade group 4 are provided with a plurality of ribs 41 having different heights, and the ribs 41 are used for filling gaps between the air guide blades and between the air guide blade group 4 and the air guide block 3, so that an air passage inside the casing is smoother. The outer contour of the fins 41 is the same as the outer contour of the outer surface of the same side of the air guide block, the fins on adjacent blades are arranged in a staggered mode, and the fins at the same height form a group. When the air guide blocks 3 are at different heights, at least one group of fins is basically aligned with the upper surface or the lower surface of the periphery of the opening of the well 31 of the air guide block 3.

The air guide vane is further provided with a vane rotating shaft 42 and a vane connecting rod rotating shaft 44 which extend along the vertical direction, wherein a single vane can rotate around the vane rotating shaft 42, and a plurality of vanes form an air guide vane group 4 through vane connecting rods 43 connected with the vane connecting rod rotating shaft 44.

When the air outlet 1 blows air in the forward direction, as shown in fig. 5, the air guide block 3 is located in the middle of the housing, and the cavity of the housing is divided into two parts which are equal up and down by the air guide block 3. After entering the casing from the casing inlet side 23, the airflow 5 is divided equally up and down by the air guide block 3, passes through the air guide block 3 and the air guide blade group 4, and then converges on the casing outlet side 24, and because the air flow rates of the upper side and the lower side are equal, the airflow 5 is blown out on the casing outlet side 24 along the horizontal direction. Wherein, the fin 41 fills the gap in the middle of the air guide block 3, so that the air passage in the shell is smooth.

When the air outlet 1 blows air upwards, as shown in fig. 6, the air guide block 3 is located at the upper part of the housing, the inner wall of the lower housing 22 forms an upward outlet at the air outlet side 24 of the housing together with the air guide block 3, and the air flow 5 is located at the lower part of the air guide block 3 and blows out from the air outlet side 24 of the housing in an upward direction. When the air guide block 3 is tightly attached to the inner wall of the upper shell 21, the upper part of the cavity of the shell is completely sealed, the upward blowing angle reaches a limit value, and the air outlet area is effectively increased. When the air outlet 1 blows air downwards, the principle is the same as that of blowing air upwards.

When the air outlet 1 blows air from left to right, the air guide blade group 4 rotates left and right, the air flow 5 is guided by the air guide blades to deflect left and right through the gap between the shell and the air guide block 3, and accordingly the air flow guided left and right is blown out on the air outlet side 24 of the shell.

The left and right rotation of the air guide blade group 4 along the blade rotating shaft 42 and the up and down movement of the air guide block 3 do not interfere with each other, and the air flow is guided to the left and right and up and down respectively. When the outlet 1 blows air upward and blows air rightward, as shown in fig. 7 and 8, the air guide block 3 is located at the upper portion of the housing, and the air guide blade group 4 is inclined rightward, so that the air flow 5 is guided rightward at the inclined angle of the blades. The fins 41 reduce the gaps of the air guide block well 31 exposed in the air passage, so that the air passage in the shell is smoother, the air guide blade group 4 can effectively guide and reduce the airflow noise.

2. Example two

As shown in fig. 9, the outlet 6 of the present invention includes an upper casing 71, a lower casing 72, an air guide block 8, and an air guide blade group 9. The air guide blade group 9 has a blade rotation shaft 93 extending in the horizontal direction, and the blade rotation shaft 93 extends to both sides of the upper casing 71 and the lower casing 72. The blade rotating shaft 93 is arranged on the side surface of the shell, so that a motor (not shown) can be conveniently arranged on the side surface of the shell, and the space occupied by the air outlet in the height direction is reduced. After the upper shell 71 and the lower shell 72 are combined, two sides of the upper shell are provided with elongated rectangular gaps, one side is an air inlet side 73, and the other side is an air outlet side 74.

In contrast to the first embodiment, the wind-guiding blade group 9 of the present embodiment includes two wind-guiding

blade strings

91 and 92, and as shown in fig. 10 and 11, the wind-guiding

blade strings

91 and 92 rotate around the blade rotation shaft 93. In this embodiment, the wind guide block 8 has a well 81 extending in the longitudinal direction, and both sides of the wind guide block 8 are provided with a U-shaped groove 82 and a square groove 83, and the blade rotation shaft 93 is installed in the U-shaped groove 82. In addition, a partition plate 10 is arranged between the two air

guide blade strings

91 and 92, a partition plate bump 101 is arranged on the partition plate 10, and the partition plate bump 101 is accommodated in the square groove 83, so that the air guide block 8 can move up and down relative to the air

guide blade strings

91 and 92.

The working principle of the air outlet 6 of this embodiment for blowing air up and down and blowing air left and right is the same as or similar to that of the first embodiment, and therefore, the description thereof is omitted.

The above embodiments are merely preferred embodiments of the present invention, which are not intended to limit the scope of the present invention, and various changes may be made in the above embodiments of the present invention.
