[0061] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0062] Currently, existing up-and-down air outlet air conditioners using axial fans have problems such as short air supply distance and high noise. An embodiment of the present invention proposes a cabinet air conditioner. By providing a wind blocking mechanism near the main axial fan, and each of the upper air outlet and the lower air outlet of the air conditioner is provided with an auxiliary air blower. By controlling the wind blocking mechanism, single upper / single lower / upper and lower simultaneous air outlet can be realized to achieve a large air volume; at the same time, through the auxiliary blowers at the upper and lower air outlets, the blown air is sent further away to achieve ultra-long air supply.

[0063] The following will Figure 1 appendix Figure 11 Elaborate on the technical solutions of this embodiment in detail. Without conflict, the following embodiments and examples can be combined with each other.

[0064] Embodiment

[0065] As Figures 1 - 11 shown, this embodiment proposes a cabinet air conditioner, including:

[0066] A housing 1, the housing 1 includes a front housing 11 on the user side and a rear housing 12 opposite to the front housing 11. The front housing 11 is provided with upper and lower air outlets 111 and 112 that are spaced apart, and the rear housing 12 is provided with an air inlet 121 between the upper air outlet 111 and the lower air outlet 112;

[0067] An air duct component 2, the air duct component 2 is accommodated inside the housing 1. The air duct component 2 includes an air duct housing, and the air duct housing includes a main air duct 21 formed with an air inlet end, a first sub-air duct 22 that communicates with the main air duct 21 and extends obliquely upward, and a second sub-air duct 23 that extends obliquely downward. The first sub-air duct 22 forms a first air outlet end communicating with the upper air outlet 111 at its extending end, and the second sub-air duct 23 forms a second air outlet end communicating with the lower air outlet 112 at its extending end;

[0068] A fan assembly, the fan assembly includes a main axial fan 3, a first auxiliary fan 4, and a second auxiliary fan 5. The main axial fan 3 is provided at the air inlet end of the main air duct 21, the first auxiliary fan 4 is provided at the first air outlet end of the first sub-air duct 22, and the second auxiliary fan 5 is provided at the second air outlet end of the second sub-air duct 23;

[0069] The wind deflector mechanism 6 is provided in the air duct housing. The wind deflector mechanism 6 has a first working position, a second working position, and a third working position;

[0070] The wind deflector mechanism is designed such that when the wind deflector mechanism 6 is in the first working position, the wind deflector mechanism 6 can connect the main air duct 21 to both the first auxiliary air duct 22 and the second auxiliary air duct 23. When the wind deflector mechanism 6 is in the second working position, the wind deflector mechanism 6 can connect the main air duct 21 to the first auxiliary air duct 22 while shutting off the connection between the main air duct 21 and the second auxiliary air duct 23. When the wind deflector mechanism 6 is in the third working position, the wind deflector mechanism 6 can connect the main air duct 21 to the second auxiliary air duct 23 while shutting off the connection between the main air duct 21 and the first auxiliary air duct 22.

[0071] In the embodiment of the present invention, a wind deflector mechanism 6 is provided near the main axial flow fan 3, and an auxiliary air blower is provided at each of the upper air outlet 111 and the lower air outlet 112 of the air conditioner. By controlling the wind deflector mechanism 6, single upper / single lower / upper and lower simultaneous air outlet is realized, achieving a large air volume; at the same time, through the auxiliary air blowers at the upper and lower air outlets, the blown air is directed further away, realizing ultra-long air supply.

[0072] Specifically;

[0073] As Figure 5 shown, when the air conditioner operates in the upper and lower simultaneous air outlet cooling / heating mode, the wind deflector mechanism 6 is in the first working position, and the main axial flow fan 3, the first auxiliary air blower 4, and the second auxiliary air blower 5 are turned on. At this time, the main air duct 21 is connected to both the first auxiliary air duct 22 and the second auxiliary air duct 23, thereby realizing upper and lower simultaneous air outlet.

[0074] As Figure 3 shown, when the air conditioner operates in the single upper air outlet cooling mode, the wind deflector mechanism 6 is in the second working position, the main axial flow fan 3 and the first auxiliary air blower 4 are turned on, and the second auxiliary air blower 5 is turned off. At this time, the main air duct 21 is connected to the first auxiliary air duct 22, thereby realizing single upper cooling air outlet.

[0075] As Figure 4 shown, when the air conditioner operates in the single lower air outlet heating mode, the wind deflector mechanism is in the third working position, the main axial flow fan 3 and the second auxiliary air blower 5 are turned on, and the first auxiliary air blower 4 is turned off. At this time, the main air duct 21 is connected to the second auxiliary air duct 23, thereby realizing single lower heating air outlet.

[0076] Preferably, the first auxiliary fan 4 and the second auxiliary fan 5 are also axial fans. The power of the main axial fan 3 is greater than the power of the first auxiliary fan 4, and the power of the first auxiliary fan 4 is greater than or equal to the power of the second auxiliary fan 5. Preferably, the power of the first auxiliary fan 4 is greater than the power of the second auxiliary fan 5. The reason why the power of the first auxiliary fan 4 is set to be greater than the power of the second auxiliary fan 5 in the embodiment of the present invention is that the first auxiliary fan 4 is arranged at the upper air outlet position, and in order to avoid more flow losses when the airflow flows upward, the power of the first auxiliary fan 4 is set to be greater than the power of the second auxiliary fan 5.

[0077] It should be noted that:

[0078] After the air conditioner runs in the upper and lower simultaneous cooling / heating air outlet mode for a period of time, the main axial flow fan 3 can be started, and the first auxiliary fan 4 and the second auxiliary fan 5 can be turned off. At this time, the wind blown out from the air outlet is soft and the air volume is small. When the room is hotter / cooler, the main axial flow fan 3 can be turned off, and the first auxiliary fan 4 and the second auxiliary fan 5 can be turned on. At this time, the air volume blown out from the upper air outlet is the smallest.

[0079] After the air conditioner runs in the upper air outlet cooling mode for a period of time and the indoor temperature is at a comfortable state, the main axial flow fan 3 can be started and the first auxiliary fan 4 can be turned off. At this time, the wind blown out from the upper air outlet 111 is gentle and the air volume is small; when the indoor temperature is already very low and the room is in a relatively cold state, the main axial flow fan 3 can be turned off and the first auxiliary axial flow fan 4 can be turned on. At this time, the air volume blown out from the upper air outlet 111 is the smallest.

[0080] After the air conditioner runs in the single bottom air outlet heating mode for a period of time and the indoor temperature is at a comfortable state, the main axial flow fan 3 can be started and the second auxiliary fan 5 can be turned off. At this time, the wind blown out from the bottom air outlet 112 is gentle and the air volume is small; when the indoor temperature is already very high and the room is in a relatively hot state, the main axial flow fan 3 is turned off and the second auxiliary fan is started. At this time, the air volume blown out from the bottom air outlet is the smallest.

[0081] In any of the above embodiments, if Figure 2 - Figure 5 As shown, the first auxiliary air duct 22 includes a first tapered air duct section 221 that is connected to the air outlet end of the main air duct 21 and extends obliquely upward, and a first straight air duct section 222 that is connected to the curved surface of the first tapered air duct section 221 and extends horizontally;

[0082] The second auxiliary air duct 23 includes a second tapered air duct section 231 communicating with the air outlet end of the main air duct 21 and extending obliquely downward, and a second straight air duct section 232 communicating with the curved surface of the second tapered air duct section 231 and extending horizontally;

[0083] Wherein, the first auxiliary fan 4 is arranged in the first straight air duct section 222, and the second auxiliary fan 5 is arranged in the second straight air duct section 232.

[0084] In the embodiment of the present invention, by setting the first auxiliary air duct 22 and the second auxiliary air duct 23 as tapered air ducts, the air pressure during air outlet is increased, thereby increasing the air outlet speed and air volume.

[0085] Further, as Figures 2 - 4 shown, the first tapered air duct section 221 includes a first air duct wall A and a first air duct wall B that are opposite and extend obliquely upward;

[0086] The second tapered air duct section 231 includes a second air duct wall A and a second air duct wall B that are opposite and extend obliquely downward;

[0087] Wherein, the first air duct wall B and the second air duct wall B are connected, and a wind blocking mechanism 6 is rotatably arranged at the connection position.

[0088] Still further, the above-mentioned wind blocking mechanism 6 includes a flow splitting and wind blocking plate rotatably arranged at the adjacent position of the first air duct wall B and the second air duct wall B;

[0089] The flow splitting and wind blocking plate includes a rotating end rotatably arranged at the adjacent position of the first air duct wall B and the second air duct wall B, and a free end opposite to the rotating end, wherein;

[0090] When the flow splitting and wind blocking plate is in the first working position, the free end of the flow splitting and wind blocking plate faces the air inlet end of the main air duct 21 and is located at the middle position of the main air duct 21;

[0091] When the flow splitting and wind blocking plate is in the second working position, the free end of the flow splitting and wind blocking plate abuts against the connection position of the main air duct 21 and the first auxiliary air duct 22 to cut off the connection between the main air duct 21 and the first auxiliary air duct 22;

[0092] When the flow splitting and wind blocking plate is in the third working position, the free end of the flow splitting and wind blocking plate abuts against the connection position of the main air duct 21 and the second auxiliary air duct 23 to cut off the connection between the main air duct 21 and the second auxiliary air duct 23.

[0093] Specifically, the above-mentioned flow splitting and wind blocking plate includes opposite first plate surface and second plate surface. In order to prevent the upper and lower shaking of the wind blocking plate caused by different pressures on the first plate surface side and the second plate surface side of the wind blocking plate, in the embodiment of the present invention, a plurality of pressure relief holes penetrating through the first plate surface and the second plate surface are arranged on the flow splitting and wind blocking plate to balance the air pressure on the first plate surface side and the second plate surface side of the flow splitting and wind guiding plate.

[0094] It should be noted that in the embodiments of the present invention, the diameter of the pressure relief holes provided on the flow splitting and wind deflecting plate is relatively small. These pressure relief holes are only used for pressure relief and will not cause significant mixing of the airflows on both sides of the flow splitting and wind deflecting plate. Preferably, the diameter of the above-mentioned pressure relief holes is designed to be 1 mm - 3 mm.

[0095] In any of the above embodiments, as Figures 2 - 5 shown, the cabinet air conditioner further includes a heat exchanger assembly 7. The heat exchanger assembly 7 is arranged at the air inlet end position of the main air duct 21 and is used for heat exchange of the air flowing into the main air duct 21.

[0096] Preferably, the heat exchanger assembly 7 and the main axial flow fan 3 are arranged in sequence in the air outlet direction of the main air duct 21.

[0097] In any of the above embodiments, as Figures 6 - 11 shown, the cabinet air conditioner further includes a wind guiding component;

[0098] The wind guiding component includes an upper wind guiding component 8 arranged at the upper air outlet 111 and a lower wind guiding component 9 arranged at the lower air outlet 112;

[0099] The upper wind guiding component includes an upper grille. The upper grille includes a first upper grille bar group 81 and a second upper grille bar group 82. The first upper grille bar group 81 and the second upper grille bar group 82 are arranged up and down. The first upper grille bar group 81 is designed to provide horizontal air outlet, and the second upper grille bar group 82 is designed to provide obliquely upward air outlet;

[0100] The lower wind guiding component 9 includes a lower grille. The lower grille is provided with a lower grille bar group 91. The lower grille bar group 91 can be driven to rotate and can form air supply in different dimensions of up, down, left, and right during the rotation process.

[0101] In the embodiments of the present invention, by providing grille bars with a certain inclination angle at the upper air outlet 111 and the lower air outlet 112, the air can be cut, and the effect of gentle air supply can be achieved.

[0102] When the air conditioner operates in the single upper air outlet cooling mode, through the upper wind guiding component with the above structure, the effect of upward air guiding can be achieved, and at the same time, the blocking effect on the air flow can be weakened.

[0103] It should be noted that the air guiding structure at the upper air outlet 111 is designed such that the grille bar group located below blows air upward and the grille bar group located above blows air obliquely upward. This is because of the positional relationship between the upper air outlet 111 and the air inlet 121. The upper air outlet 111 is located above the air inlet 121. When the air flow entering from the air inlet 121 reaches the position of the upper air outlet 111, there will be a certain flow loss. In order to avoid excessive loss of flow velocity and flow rate after passing through the upper air guiding component, the upper air guiding component is set such that the grille bar group located below blows air upward and the grille bar group located above blows air obliquely upward. Thus, while achieving the effect of guiding air obliquely upward, {it can prevent cold air from directly hitting people, and at the same time make the cold air gradually fall from above to below, improving the refrigeration effect}, and it can also weaken the blocking effect on the air flow.

[0104] When the air conditioner operates in the heating mode, the lower air guiding component can be set to guide air downward. On the one hand, this can prevent hot air from directly blowing on people, and on the other hand, it can direct the hot air flow downward, enabling the hot air to gradually rise from below to above, thereby improving the heating effect.

[0105] Furthermore, as Figures 7 - 9 shown, the first upper grille bar group 81 includes a plurality of first upper grille bars 811 arranged from bottom to top. The plurality of first upper grille bars 811 are all parallel to the central axis of the upper grille. The second upper grille bar group 82 includes a plurality of second upper grille bars 821 arranged from top to bottom;

[0106] Among them, the angle between the adjacent two second upper grille bars 821 in the plurality of second upper grille bars 821 arranged from bottom to top and the central axis of the upper grille is designed as follows: the lower second upper grille bar 821 forms a first included angle with the central axis of the upper grille, and the upper second upper grille bar 821 forms a second included angle with the central axis of the upper grille, where the first included angle is greater than the second included angle.

[0107] Furthermore, as Figure 10 and Figure 11 shown, the lower grille bar group 91 includes a plurality of lower grille bars 911. The plurality of lower grille bars 911 can be driven to rotate synchronously around the axis of the lower grille, and an air flow channel 912 for air flow to pass through is formed between the adjacent two lower grille bars 911. The air outlet direction of the air flow channel 912 is not parallel to the rotation axis of the lower grille.

[0108] Specifically, the plurality of lower grille bars 911 are arranged in parallel, and an angle a is formed between the grille plane of each lower grille bar 911 and the rotation axis of the lower grille, where 0° < a < 90°.

[0109] It should be noted that the above-mentioned lower grille further includes:

[0110] The outer ring 913 of the lower grille, and a plurality of lower grille bars 911 are fixedly arranged inside the outer ring 913 of the lower grille. The outer ring 913 of the lower grille and the plurality of lower grille bars 911 can be driven to rotate synchronously around the axis of the outer ring 913 of the grille;

[0111] A connecting member 914, the connecting member 914 is fixedly connected to the lower grille bar 911, and a motor shaft hole is provided at the center position of the outer ring 913 of the lower grille on the connecting member 914;

[0112] A motor 915, the output shaft end of the motor 915 is shaft-connected to the motor shaft hole to directly drive the plurality of lower grille bars to rotate synchronously through the motor 915.
