[0067] Referring to Figure 1 , Figure 2 and Figure 7 As shown in FIG. 1, in some embodiments, the air inlet 300 comprises a first bottom plate 370 and a first surrounding plate 360, the first bottom plate 370 is horizontally extended, the first surrounding plate 360 is a ring, the first surrounding plate 360 is connected to the top of the first bottom plate 370, the first surrounding plate 360 is arranged along the periphery of the first bottom plate 370, the first surrounding plate 360 and the first bottom plate 370 can be connected by buckles or fasteners, the first surrounding plate 360 and the first bottom plate 370 can also be an integral structure, a plurality of air inlets 310 are arranged on the first surrounding plate 360, the plurality of air inlets 310 are arranged along the circumferential direction of the first surrounding plate 360, a second opening 320 is arranged at the center of the first bottom plate 370, the first bottom plate 370 can be square, and the second opening 320 can be circular. The air outlet 400 comprises a second bottom plate 4016 and a second surrounding plate 4015, the second bottom plate 4016 is horizontally extended, the second surrounding plate 4015 is a ring, the second surrounding plate 4015 is connected to the top of the second bottom plate 4016, the second surrounding plate 4015 is arranged along the periphery of the second bottom plate 4016, a plurality of first air outlets 410 are arranged on the second surrounding plate 4015, the plurality of first air outlets 410 are arranged along the circumferential direction of the second surrounding plate 4015, the second surrounding plate 4015 and the second bottom plate 4016 can be connected by buckles or fasteners, and the second surrounding plate 4015 and the second bottom plate 4016 can also be an integral structure.

[0068] In this embodiment, the shape and structure of the air inlet part 300 and the air outlet part 400 are described in detail. The air inlet part 300 and the air outlet part 400 have simple structure and small space occupation. When the air inlet part 300 and the air outlet part 400 are in the retracted position, they are retracted into the shell 100 and integrated with the ceiling, and the appearance effect is good.

[0069] Referring to Figure 1 and Figure 2 In some embodiments, the bottom of the air outlet part 400 is provided with a second air outlet 420, and the second air outlet 420 is provided with a rotatable air deflector 430. The air deflector 430 can be square, circular or other shapes. The air deflector 430 can open or close the second air outlet 420. The rotation axis of the air deflector 430 is arranged in the horizontal direction, as shown in Figure 4 When the air deflector 430 closes the second air outlet 420, the air deflector 430 is in a horizontal state, as shown in Figure 14 When the air deflector 430 completely opens the second air outlet 420, the air deflector 430 is in a vertical state, as shown in Figure 11 and Figure 12 The air deflector 430 can also partially open the second air outlet 420, thereby playing a wind guiding role. The fan 200 can be an axial fan 200 or a centrifugal fan 200, mainly driving the airflow in the cavity 110 to flow from top to bottom. When the ceiling machine 1000 is in the cooling mode, as shown in Figure 8 The air deflector 430 can close the second air outlet 420, so that the cold air flows out of the first air outlet 410 in the horizontal direction. At this time, the cold air will not blow directly on the human body, thereby achieving the effect of preventing direct blowing. When the ceiling machine 1000 is in the heating mode, as shown in Figure 13 The air deflector 430 can open the second air outlet 420, so that part of the hot air flows vertically downward from the second air outlet 420. The hot air has good warm feet effect, and can solve the problem that the traditional ceiling machine 1000 cannot blow hot air to the floor, thereby causing poor heating effect. The ceiling machine 1000 of the present embodiment can simultaneously consider the effects of cooling air outlet and heating air outlet by arranging the air deflector 430.

[0070] It should be noted that when the ceiling machine 1000 is in the cooling mode or the heating mode, the air deflector 430 can open the second air outlet 420, and the air deflector 430 can reciprocate, thereby achieving the air sweeping effect of cold air or hot air.

[0071] It can be understood that when the ceiling machine 1000 is in the cooling mode, the air deflector 430 closes the second air outlet 420. Since the air deflector 430 is located at the bottom of the air outlet part 400, the airflow driven by the fan 200 flows from top to bottom, directly hits the air deflector 430, and causes the flow rate of the airflow to decrease, thereby affecting the distance of the airflow flowing in the horizontal direction.

[0072] Based on this, referring to Figure 2 shown, in some embodiments, the fan 200 adopts a double-impeller structure, the fan 200 includes a first impeller 210, a second impeller 220, a first motor 240 and a second motor 250, the first impeller 210 is located above the second impeller 220, the first motor 240 drives the first impeller 210 to rotate alone, the second motor 250 drives the second impeller 220 to rotate alone, the first impeller 210 and the second impeller 220 are coaxially arranged, the rotation axis of the first impeller 210 and the rotation axis of the second impeller 220 are parallel to each other, and are arranged along the up-down direction, wherein the second impeller 220 is a centrifugal impeller, that is, the second impeller 220 takes in air along the axial direction and discharges air along the radial direction, or the second impeller 220 takes in air along the radial direction and discharges air along the axial direction, which depends on the rotation direction of the second impeller 220. The first impeller 210 can be a centrifugal impeller or an axial flow impeller, the first impeller 210 mainly guides the airflow to flow from top to bottom, and the second impeller 220 mainly changes the flow direction of the airflow discharged by the first impeller 210 or enhances the flow rate of the airflow flowing from top to bottom, playing an auxiliary role.

[0073] It should be noted that the rotation direction of the first impeller 210 and the rotation direction of the second impeller 220 will affect the flow direction of the airflow, which will be illustrated by way of example below.

[0074] Referring to Figure 8 shown, when the ceiling machine 1000 is in the cooling mode, the air deflector 430 closes the second air outlet 420, and the second impeller 220 rotates reversely relative to the first impeller 210, that is, the rotation direction of the first impeller 210 is opposite to the rotation direction of the second impeller 220, for example, the first impeller 210 rotates along the first direction in Figure 8 at this time, the first impeller 210 guides the airflow in the cavity 110 to flow from top to bottom, if only the first impeller 210 is arranged, the airflow flowing from top to bottom will directly hit the air deflector 430, affecting the horizontal air outlet distance, therefore, the second impeller 220 is also arranged in the embodiment, the second impeller 220 rotates along the second direction in Figure 8 , the second direction is opposite to the first direction, so that the second impeller 220 takes in air along the axial direction and discharges air along the radial direction, the second impeller 220 can guide the airflow in the cavity 110 to flow along the horizontal direction, since the second impeller 220 is located below the first impeller 210, it can change the flow direction of the airflow discharged by the first impeller 210 in advance, thereby guiding the airflow in the cavity 110 to flow along the horizontal direction and deviate to the first air outlet 410, such an arrangement can increase the air outlet distance of the airflow along the horizontal direction, and the sky curtain air effect formed is better.

[0075] Referring to Figure 14As shown, when the air conditioner 1000 is in heating mode, the air guide plate 430 opens the second air outlet 420, and the first impeller 210 and the second impeller 220 rotate in the same direction, that is, the rotation direction of the first impeller 210 is the same as the rotation direction of the second impeller 220. For example, both the first impeller 210 and the second impeller 220 rotate in the same direction. Figure 12 The first impeller 210 rotates in the first direction, causing the airflow in the cavity 110 to flow from top to bottom. The second impeller 220 draws in air radially and discharges air axially, thereby guiding the airflow in the cavity 110 from top to bottom to the second air outlet 420. Since the second air outlet 420 is located at the bottom of the air outlet 400 and faces the floor, the impact of the warm air on the floor can be strengthened, allowing the warm air to land on the floor and then diffuse to the periphery of the floor, resulting in a better foot warming effect and greatly improving the comfort of heating and foot warming.

[0076] Reference Figure 2 and Figure 4 As shown, in some embodiments, the first impeller 210 is an axial flow impeller, and the outer diameter of the first impeller 210 is larger than the outer diameter of the second impeller 220. This allows the first impeller 210 to cover the second impeller 220 in the vertical direction, forming an inset layout between the first impeller 210 and the second impeller 220. The size relationship between the outer diameters of the two impellers can also be adapted. Along the cross section perpendicular to the axis of the first impeller 210, the second impeller 220 will not block the blades of the first impeller 210, and the second impeller 220 has a small impact on the air volume of the first impeller 210.

[0077] Reference Figure 2 and Figure 3 As shown, in some embodiments, the fan 200 includes a guide shroud 230, the top of which is closed, located below the first impeller 210, surrounding the outer periphery of the second impeller 220, and fixedly disposed within the cavity 110. The guide shroud 230 is fixed relative to the second impeller 220. The outer peripheral wall of the guide shroud 230 has multiple first ventilation openings 231, which can be understood as forming a grid structure. The multiple first ventilation openings 231 are arranged at intervals along the circumference of the second impeller 220. The bottom of the guide shroud 230 has second ventilation openings 232, located below the second impeller 220. The guide shroud 230 can also be understood as forming a volute structure outside the second impeller 220, mainly used to guide airflow through the second impeller 220. Specifically, refer to...

In this way, the air guide cover 230 can guide the air flow at the air outlet side of the second impeller 220 to flow in the horizontal direction, thereby changing the flow direction of the air flow at the air outlet side of the first impeller 210 and making the air flow deviate towards the first air outlet 410. Figure 3 and Figure 14 As shown, when the second impeller 220 rotates reversely relative to the first impeller 210, the second impeller 220 sucks air through the second air vent 232, and the second impeller 220 blows air through the first air vent 231. In this way, the air guide cover 230 can guide the air flow at the air outlet side of the second impeller 220 to flow in the horizontal direction, thereby changing the flow direction of the air flow at the air outlet side of the first impeller 210 and making the air flow deviate towards the first air outlet 410.

[0078] As shown, when the second impeller 220 rotates reversely relative to the first impeller 210, the second impeller 220 sucks air through the second air vent 232, and the second impeller 220 blows air through the first air vent 231. In this way, the air guide cover 230 can guide the air flow at the air outlet side of the second impeller 220 to flow in the horizontal direction, thereby changing the flow direction of the air flow at the air outlet side of the first impeller 210 and making the air flow deviate towards the first air outlet 410. Figure 3 As shown, in some embodiments, the air guide cover 230 comprises a thickened portion 233, the thickened portion 233 is annular, and the thickened portion 233 is located at a position below the first air vent 231. The thickened portion 233 can be understood as relatively increasing the thickness of the local structure of the air guide cover 230.

Figure 2 and Figure 3 As shown, in some embodiments, the ceiling machine 1000 further comprises a connecting ring 440, the connecting ring 440 is annular, and the connecting ring 440 is rotatably arranged at the second air outlet 420. The connecting ring 440 rotates with the air outlet member 400, the rotation axis of the connecting ring 440 is parallel to the height direction of the shell 100, the air guide plate 430 is located in the connecting ring 440, and the air guide plate 430 is rotatably connected with the connecting ring 440. After being arranged in this way, the air guide plate 430 can not only rotate around the horizontal axis, but also rotate around the vertical axis. For example, the connecting ring 440 can rotate around the vertical axis relative to the air outlet member 400, and the air guide plate 430 can rotate around the horizontal axis relative to the connecting ring 440. The rotation angle of the air guide plate 430 can be adjusted to make the air guide plate 430 guide air in any direction, thereby realizing no-dead-angle air outlet and good air outlet effect.

[0080] As shown, in some embodiments, the air guide cover 230 comprises a thickened portion 233, the thickened portion 233 is annular, and the thickened portion 233 is located at a position below the first air vent 231.

For example, the flow guide wall 234 is arc-shaped, and the inner diameter of the flow guide wall 234 increases first and then decreases from top to bottom.

The output end of the first rotary driving device 460 is provided with a first gear 470, and the first gear 470 is engaged with the first rack 450. Through the cooperation of the first gear 470 and the first rack 450, the first rotary driving device 460 can drive the connecting ring 440 to rotate 180° relative to the air outlet 400 around the axis in the up-down direction. The transmission structure of the present embodiment occupies a smaller space and is easy to assemble.

[0082] Referring to Figure 15 As shown, in some embodiments, the air deflector 430 is provided with a plurality of air outlets 432, and the plurality of air outlets 432 are all in communication with the cavity 110.

The air outlets 432 are windless micro-holes, and the diameter of the air outlets 432 satisfies the range of 1.5mm-6mm (including the end point value). For example, the diameter of the air outlets 432 can be 1.5mm or 6mm. The smaller diameter of the air outlets 432 can weaken the flow rate of the airflow, so as to achieve the effect of windless air outlet. Even if the airflow blows straight down, the user will not feel obvious blowing feeling, which effectively prevents the cold air from directly blowing the user's head.

When the ceiling machine 1000 is in the cooling mode, the rotating piece 4011 is in the second rotating position, thereby connecting the first air outlets 410 and the cavity 110, so that the first air outlets 410 can blow air horizontally.
