Fig. 4 is a schematic structural view of one direction of the yaw blade 130a of the indoor unit 100 of the floor air conditioner according to an embodiment of the present invention, and fig. 5 is a schematic structural view of the other direction of the yaw blade 130a of the indoor unit 100 of the floor air conditioner according to an embodiment of the present invention.

In some embodiments, as shown in fig. 4 and 5, each of the yaw lobes 130a may include a lobe body having two opposing sides 130a5 extending in a transverse direction that are each contoured and the lobe body smoothly transitions from one of the sides 130a5 to the other side 130a5 such that the surface of the lobe body exhibits an undulating, undulating shape. When the airflow at the air outlet 100a passes through the horizontal swinging blade 130a, the airflow is guided by the undulation shape of the blade body surface and is blown out from different directions, so that the air outlet range is expanded, the air outlet shunting is realized, and the blown airflow is closer to the natural wind effect. As shown in fig. 2, the lateral direction refers to the left-right direction.

As shown in fig. 5, the wave shape of the outboard side 130a5 of the leaflet body includes two valley sections 130a6 and one peak section 130a7, and the wave shape of the inboard side 130a5 includes one valley section and two peak sections. Wherein the length of the peak section may be equal to the length of the valley section. After the airflow is guided by the blade body with the structure, the air outlet is more uniform, and the air supply distance can be lengthened. The airflow at the air outlet is guided by the horizontal swinging blades to flow from the side 130a5 at the inner side to the side 130a5 at the outer side, wherein the side at the inner side can be referred to as a windward side, and the side at the outer side can be referred to as an air outlet side.

The peak section 130a7 of the outboard side 130a5 of the leaflet body is opposite the valley section of the inboard side 130a5 and the valley section 130a6 of the outboard side 130a5 is opposite the peak section of the inboard side 130a5, i.e., the waveforms of the outboard side 130a5 and the inboard side 130a5 are out of phase by one half cycle. The blade body of design has further promoted the air supply homogeneity for the air current that blows off is close natural wind more, and has further guaranteed the air supply distance.

In this embodiment, the amplitude of the peak section 130a7 of the outboard side 130a5 of the lobe body is the same as the amplitude of the valley section of the inboard side 130a5 of the lobe body, and the amplitude of the valley section 130a6 of the outboard side 130a5 of the lobe body is the same as the amplitude of the peak section of the inboard side 130a5 of the lobe body. Wherein the maximum amplitude of the wave shape may be 1.2 to 1.3 times the thickness of the leaf body. The arrangement can enable the guide angle of the blade body of the horizontal swinging blade 130a to the air outlet to be within a reasonable range.

Referring again to fig. 4, at least one side surface of the vane body is formed with a plurality of pockets 130a4 that do not penetrate the vane body, and optionally, both side surfaces of the vane body are formed with a plurality of pockets 130a 4. The blade body designed in this way can enhance the turbulence characteristic of the airflow flowing through the surface of the blade body, so that the airflow forms a vortex boundary layer on the surface of the blade body, thereby isolating the cold airflow and the blade body during refrigeration operation and improving the condensation phenomenon on the surface of the blade body. In addition, the existence of the pits 130a4 can also reduce the wind outlet strength, so that the blown air flow is more comfortable.

The concave pit 130a4 may be a spherical pit or a polyhedral pit, preferably a spherical pit, which is easy to manufacture and can make smooth wind guidance by its smooth shape. The rounded transition between the pockets 130a4 and the surface of the blade body reduces flow resistance.

In some embodiments, the fixed rotational shaft 130a1 and the moving rotational shaft 130a2 of the yaw blade 130a are positioned such that: when the swing blade 130a swings around the fixed rotation shaft 130a1 to a position substantially parallel to the horizontal plane, the axis of the movable rotation shaft 130a2 is lower than the axis of the fixed rotation shaft 130a 1.

In the prior art, the positions of the fixed rotating shaft 130a1 and the movable rotating shaft 130a2 generally satisfy the following requirements: when the swing blade 130a swings around the fixed rotation shaft 130a1 to a position substantially parallel to the horizontal plane, the axis of the movable rotation shaft 130a2 is at the same height position as the axis of the fixed rotation shaft 130a 1. In the present embodiment, by changing the position of the movement rotating shaft 130a2 of the yaw blade 130a, the swing amplitude of the yaw blade 130a can be increased, that is, the swing angle of the yaw blade 130a of the present embodiment is larger than that of the yaw blade 130a of the related art as described above when the link 130b moves by the same amplitude.

Specifically, referring again to fig. 4, the fixed rotation shaft 130a1 extends laterally from the side of the yaw blade 130a adjacent to the link 130b in the direction of the volute tongue 181, the side of the yaw blade 130a adjacent to the link 130b is formed with an extension plate 130a3 protruding inwardly, and the moving rotation shaft 130a2 extends laterally from the extension plate 130a3 to be connected to the link 130 b.

When the people mode is not blown in first refrigeration, a plurality of horizontal swinging blades 130a in the upper horizontal swinging blade group 131 and a plurality of horizontal swinging blades 130a in the lower horizontal swinging blade group 132 are all controlled to swing upwards to be at a first preset angle with the horizontal plane, and the cold air in the whole area of the air outlet 100a is blown out upwards, so that the human body can not be blown out downwards, the air supply comfort is improved, and the cold air has a sinking trend, so that the temperature distribution of the whole room is more uniform, and the body feeling comfort of a user is improved.

In the second cooling no-blowing mode, the plurality of horizontal swing blades 130a in the upper horizontal swing blade group 131 are controlled to swing to a position approximately parallel to the horizontal plane, so that the cold air on the upper portion is blown out horizontally forward, the plurality of horizontal swing blades 130a in the lower horizontal swing blade group 132 are controlled to swing upward to form a second preset angle with the horizontal plane, the cold air on the lower portion is blown out upward, the effect that no direct blowing is performed below a certain height in front of an air conditioner is achieved, the head of a child and the legs of an old person cannot be blown, and meanwhile the cooling effect and the air supply distance can be guaranteed.

In some embodiments, the first preset angle and the second preset angle range from 55 ° to 65 °, for example, the first preset angle and the second preset angle may be 55 °, 60 °, or 65 °.

As shown in table 1, all the traverse blades 130a in the upper traverse blade group 131 swing upward by 60 °, and wind speeds at different angles, different distances, and different heights with respect to the air conditioner are measured, where the different angles with respect to the air conditioner are 30 ° left, 0 ° right, and 30 ° right, the different distances are 0.5m, 1.0m, 1.5m, and 2.0m, and the different heights are 1.2m and 1.5m, respectively. The measured values of wind speed are shown in table 1.

Table 1 wind speed measurement at different angles, different distances, and different heights with respect to the indoor unit 100

As can be seen from table 1, all the traverse blades 130a in the upper traverse blade group 131 swing upward to form 60 ° with the horizontal plane, the front distance is about 1m from the indoor unit, the height is below 1.5m, the wind speed at each position of three different angles relative to the indoor unit 100 is lower than 0.6m/s, the wind speed reaches the national standard zero level of "wind power class", is soft wind, has good effect of not directly blowing, and is comfortable in air supply.

All the transverse swinging blades 130a in the upper transverse swinging blade group 131 swing upwards to form a 60-degree angle with the horizontal plane, the distance between the front side of the transverse swinging blades is about 1.5m, the height of the transverse swinging blades is less than 1.5m, the wind speed of each position of three different angles relative to the indoor unit 100 is less than 0.2m/s, the wind speed reaches the national standard zero level of wind power level, the transverse swinging blades are windless, the head of a child and the legs of the old can be well prevented from catching a cold, and the use experience of a user is improved.

When the horizontal swinging blades 130a in the upper horizontal swinging blade group 131 in the indoor unit 100 of the floor air conditioner of the embodiment swing upward by 60 degrees, the horizontal swinging blades 130a can guide the wind in the upward direction, so that the human body can stand on the front of the indoor unit 100 and can not be blown directly.

When the horizontal swing blade 130a with the micropores swings up 60 degrees in the prior art, the air supply distance is short, and the air volume loss is large. The air volume loss when the yaw blade 130a of the present embodiment swings up 60 ° is smaller than the air volume loss when the yaw blade 130a swings up 60 ° with the micropores of the prior art, and the air blowing distance of the yaw blade 130a of the present embodiment is much larger than the air blowing distance of the yaw blade 130a with the micropores.
