The current air conditioner air guiding mechanism generally consists of a wind deflector provided at the air outlet of the indoor unit of the air conditioner and a driving mechanism for driving the wind deflector to swing. The wind deflector rotates around the fixed rotating shaft under the driving of the driving mechanism. For a single-cooled air conditioner, due to the single operation mode, the position of the shaft on the wind deflector can be adjusted by designing to find the best position to control the direction of the wind, so as to improve the control of the wind direction of the air conditioner, thereby adjusting the room. The purpose of comfort. However, for the air-conditioning type, the air conditioner is in two operating modes. When the air is cooled, the air is blown upwards, the air is blown upwards, the air is light when heating, and the wind needs to be blown downwards. The requirements are exactly the opposite. Therefore, when the air guiding mechanism with a fixed rotating shaft is used, the need for different air guiding angles in the two modes of cooling and heating cannot be met. For this reason, we applied to the Patent Office for a name in 2008.

By controlling the rotation angle of the gear plate 4, the opening degree of the wind deflector 7 can be controlled to achieve the cooling state and the cold air is sent upward. When heating, the upper motor 61 controls the upper buckle 1 to hook the upper buckle 70 of the air deflector 7, and the lower motor 62 drives the lower buckle 1 to be disengaged from the lower buckle 71 of the air deflector 7, at this time, the gear disc 4 is in the motor 60. The pinion 5 is driven to rotate, and the air guiding plate 7 is pushed by the movable hinged link 3 to rotate the connecting line of the upper buckle 70 on the left and right sides of the air guiding plate 7 as a rotating shaft, and the motor 60 passes through the control gear wheel 4.

An air conditioner 1 according to an embodiment of the present invention will now be described with reference to Figs. As shown in Figs. 8-11, an air conditioner 1 according to an embodiment of the present invention includes a body 10, an air outlet frame 20, a wind deflector 30, a first drive motor 40, and a second drive motor 50.

The body 10 has a duct 11 , and the air outlet frame 20 is disposed on the body 10 , and the air outlet frame 20 has an air outlet 21 communicating with the air duct 11 . The air deflector 30 is pivotally disposed on the air outlet frame 20 between the closed position where the air outlet 21 is closed, the upper air guiding position of the upward air guiding, and the lower air guiding position of the downward air guiding, wherein the air guiding plate 30 is disposed. The inner air deflector 31 and the outer air deflector 32 are pivotally disposed on the air outlet frame 20 and the outer air deflector 32 is pivotally disposed on the inner air deflector 31. The first driving motor 40 is disposed on the air outlet frame 20, and the first driving motor 40 is coupled to the inner air guiding plate 31 to drive the inner air guiding plate 31 to pivot. The second driving motor 50 is disposed on the inner air guiding plate 31, and the second driving motor 50 is connected to the outer air guiding plate 32 to drive the outer air guiding plate 32 to pivot.

Next, a control method of the air conditioner 1 according to an embodiment of the present invention will be described with reference to Figs. 8-11 and 13, which includes:

When the air conditioner 1 is in the closed state, each of the inner air deflector 31 and the outer air deflector 32 is in the closed position.

When the air conditioner 1 enters the cooling mode, each of the inner air deflector 31 and the outer air deflector 32 pivots counterclockwise from the closed position to the upper air guiding position.

When the air conditioner 1 enters the heating mode, the inner air deflector 31 pivots counterclockwise from the closed position to the lower air guiding position, and the outer air deflector 32 pivots clockwise from the closed position Lower guide air position.

In other words, when the air conditioner 1 is in the cooling mode, the inner air deflector 31 and the outer air deflector 32 may be located at the upper air guiding position. When the air conditioner 1 is in the heating mode, the inner air deflector 31 and the outer air deflector 32 may be located at the lower air guiding position.

Specifically, when the air conditioner 1 enters the cooling mode, the air deflector 30 is pivoted from the closed position to the upper air guiding position. Specifically, the inner air deflector 31 and the outer air deflector 32 pivot relative to the air outlet frame 20, and the inner air deflector 31 and the outer air deflector 32 are pivoted from the closed position to the upper air guiding position. The deflector 31 and the outer deflector 32 may be relatively stationary (the inner deflector 31 and the outer deflector 32 are pivoted counterclockwise from the position shown in FIG. 8 to the position shown in FIG. 9). When the air conditioner 1 enters the heating mode, the air deflector 30 is pivoted from the closed position to the lower air guiding position. Specifically, the inner air deflector 31 and the outer air deflector 32 pivot relative to the air outlet frame 20 and the outer air guide panel 32 pivots relative to the inner air deflector 31, and the inner air deflector 31 and the outer air deflector 32 are The closed position is pivoted to the lower air guiding position (the inner deflector 31 and the outer deflector 32 are pivoted from the position shown in FIG. 8 to the position shown in FIG. 11), and the inner deflector 31 is counterclockwise The outer deflector 32 is pivoted clockwise. Specifically, the inner air deflector 31 and the outer air deflector 32 can be pivoted at the same time, and the outer air deflector 32 can also pivot to the transition position shown in FIG. 10 with the inner air deflector 31, and then the inner guide. The wind plate 31 pivots.

In a specific example of the present invention, the control method of the air conditioner 1 includes the following steps:

When the air conditioner 1 enters the cooling mode, the first drive motor 40 rotates 40 degrees counterclockwise, that is, the first drive motor 40 drives each of the inner air deflector 31 and the outer air deflector 32 to rotate counterclockwise by 40 degrees. Describe the position of the wind guide. When the air conditioner 1 exits the cooling mode, the first drive motor 40 rotates 40 degrees clockwise, that is, the first drive motor 40 drives each of the inner air deflector 31 and the outer air deflector 32 to rotate clockwise by 40 degrees. Describe the closed position.

When the air conditioner 1 enters the heating mode, the first drive motor 40 rotates counterclockwise by 97 degrees, that is, the first drive motor 40 drives each of the inner air deflector 31 and the outer air deflector 32 to rotate counterclockwise by 97 degrees. At this time, the inner air deflector 31 is located at the lower air guiding position. Then, the second drive motor 50 is rotated 174 degrees clockwise, that is, the second drive motor 50 drives the outer air guide plate 32 to rotate clockwise by 174 degrees, at which time the outer air guide plate 32 is located at the lower air guide position. When the air conditioner 1 exits the heating mode, the second drive motor 50 rotates 174 degrees counterclockwise, that is, the second drive motor 50 drives the outer air deflector 32 to rotate counterclockwise by 174 degrees, and then the first drive motor 40 rotates clockwise 97. That is, the first drive motor 40 drives each of the inner deflector 31 and the outer deflector 32 to rotate clockwise by 97 degrees to the closed position.

Further, the air conditioner 1 can also be switched between the upper air guiding mode and the lower air guiding mode, i.e., the air guiding plate 30 can be pivoted between the upper air guiding position and the lower air guiding position. When the air guiding plate 30 is pivoted from the upper air guiding position to the lower air guiding position, the inner air guiding plate 31 and the outer air guiding plate 32 pivot relative to the air guiding frame 20 and the outer air guiding plate 32 is opposite to the inner guiding portion. The wind plate 31 pivots, and the inner air deflector 31 and the outer air deflector 32 are pivoted from the upper air guiding position to the lower air guiding position. Specifically, the inner air deflector 31 and the outer air deflector 32 can be pivoted simultaneously (the inner air deflector 31 and the outer air deflector 32 are pivoted from the position shown in FIG. 9 to the position shown in FIG. The air deflector 31 pivots counterclockwise and the outer air deflector 32 pivots clockwise. The outer air deflector 32 can also pivot first with the inner air deflector 31 and then pivot relative to the inner air deflector 31 (internal wind guide) The plate 31 and the outer air deflector 32 are pivoted from the position shown in FIG. 9 to the position shown in FIG. 10, and then pivoted to the position shown in FIG. 11, and the inner air deflector 31 pivots counterclockwise and guides the wind. The plate 32 is pivoted counterclockwise and then pivoted clockwise). In Fig. 10, the inner air deflector 31 is located at the lower wind guide position.

The process of pivoting the inner air deflector 31 and the outer air deflector 32 from the lower air guiding position to the upper air guiding position and the inner air guiding plate 31 and the outer air guiding plate 32 are pivoted from the upper air guiding position The process to the lower wind guide position is reversed and will not be described in detail herein.

In other words, the inner air deflector 31 and the outer air deflector 32 are pivotally disposed on the air outlet frame 20 between the closed position, the upper air guiding position and the lower air guiding position, and the outer air guiding wind The plate 32 is pivotally disposed between the closed position and the lower air guiding position and between the upper air guiding position and the lower air guiding position on the inner wind deflector 31.

The existing air conditioner has only one air deflector (corresponding to the outer air deflector 32). Since the air deflector and the air outlet frame interfere with each other, the air deflector of the existing air conditioner cannot be moved to the lower guide. Wind position, not conducive to hot air in the space Diffusion, circulation.

The air conditioner 1 according to an embodiment of the present invention is provided by an inner wind deflector 31 pivotally mounted on the air outlet frame 20 and an outer air deflector 32 pivotally mounted on the inner air deflector 31, The structural unit can pivot the outer air deflector to the upper air guiding position, and can also pivot the outer air guiding plate 32 to the lower air guiding position. Since the outer air deflector 32 can be pivoted to the lower air guiding position, the wind blown through the air duct 11 can be guided to the lower side of the body 10. If the wind blown through the air duct 11 is hot air, the hot air is guided downward, thereby facilitating the diffusion and circulation of the hot air in the space (that is, accelerating the diffusion and circulation of the hot air in the space), that is, the temperature in the space can be quickly Raised to a predetermined temperature, the outer deflector is easier to operate and the air guiding effect is better.

Moreover, the air conditioner 1 according to the embodiment of the present invention is provided with an inner wind deflector 31 pivotally mounted on the air outlet frame 20 and an outer air guide pivotally mounted on the inner air deflector 31. The plate 32 can thereby increase the air guiding distance of the outer air guiding plate 32, thereby further facilitating the diffusion and circulation of the hot air in the space, and making the human body feel more comfortable.

By using the control method of the air conditioner 1 according to the embodiment of the present invention, it is possible to facilitate the diffusion and circulation of hot air in the space, that is, the temperature in the space can be quickly reached to a predetermined temperature.

As shown in FIG. 11, in some embodiments of the present invention, in the lower air guiding position, the upper edge 321 of the outer air deflector 32 may be adjacent to the upper edge 211 of the air outlet 21, and the lower outer air deflector 32 The 322 can extend downwardly and outwardly. This makes it possible to better guide the wind blown out through the duct 11 to the lower side of the body 10, thereby facilitating the diffusion and circulation of hot air in the space. Wherein, the up and down direction is as indicated by an arrow A in Figs. 8-11, and the outward extension extends in a direction away from the air passage 11 and the air outlet 21. The wind blown through the duct 11 may first pass through the air outlet 21 and then move downward under the guidance of the outer air deflector 32. At this time, the upper edge 321 of the outer air deflector 32 may be located outside the air outlet 21.

Advantageously, as shown in FIG. 11 and FIG. 12, the upper edge 321 of the outer air deflector 32 can extend into the air duct 11, that is, the upper edge 321 of the outer air deflector 32 can pass inward through the air outlet 21, so that It further facilitates the diffusion and circulation of hot air in the space.

As shown in FIG. 11, in an embodiment of the present invention, in the lower air guiding position, the lower edge 312 of the inner air deflector 31 may be adjacent to the air outlet 21, and the lower edge 312 of the inner air deflector 31 may be The lower edge 212 of the air outlet 21 is spaced apart by a predetermined distance, and the upper edge 311 of the inner air deflector 31 may extend downward and outward. This makes it possible to better guide the wind blown through the duct 11 to the lower side of the body 10, so that it is further advantageous for the hot air to diffuse and circulate in the space.

As shown in FIG. 9, in one example of the present invention, in the upper air guiding position, each of the lower edge 312 of the inner air deflector 31 and the lower edge 322 of the outer air deflector 32 may be adjacent to the air outlet. The lower edge 212 of the 21, and each of the upper edge 311 of the inner air deflector 31 and the upper edge 321 of the outer air deflector 32 may extend generally horizontally outward. This can better guide the wind blown through the duct 11 to the upper side of the body 10, thereby facilitating the diffusion and circulation of the cold air in the space, that is, the temperature in the space can be quickly lowered to a predetermined temperature.

The wind blown through the air duct 11 may first pass through the air outlet 21 and then move upward under the guidance of the inner air deflector 31 and the outer air deflector 32. At this time, the lower edge 312 of the inner air deflector 31 and the outer air deflector 32 Each of the lower edges 322 may be located outside of the air outlet 21.
