[0098] When the front upper air guide plate 32 is controlled to rotate and the other end of the front upper air guide plate 32 is close to the top wall 11, the front upper air outlet 121 can discharge air toward the front and lower part of the front upper air outlet 121;

[0099] The inclination angle of the lower bending wall 124 relative to the main shell wall 123 is α, and the inclination angle of the front upper air guide plate 32 relative to the upper bending wall 125 is β, which satisfies: 20°≤α≤50°, 20°≤β≤45°; by designing the inclination angle of the lower bending wall 124 and the inclination angle of the front upper air guide plate 32, the air outlet direction can be accurately controlled, and the air supply comfort of the whole machine can be improved; the front upper air outlet 121 is a hidden design, which improves the aesthetics of the whole machine;

[0100] Preferably, α=45°, β=45°, that is, the inclination angle of the lower bending wall 124 is the same as the inclination angle of the upper bending wall 125 .

[0101] In view of the problem that the air outlet direction of the front lower air outlet 122 cannot be adjusted, the present embodiment proposes that the air guide mechanism includes a front lower air guide mechanism, the front lower air guide mechanism includes a front lower air guide plate 33, and one end of the front lower air guide plate 33 is rotatably disposed on the upper edge of the front lower air outlet 122;

[0102] When the front lower air guide plate 33 is controlled to rotate and the other end of the front lower air guide plate 33 is close to the lower air outlet 23 , the front lower air outlet 122 can discharge air toward the upper front of the front lower air outlet 122 .

[0103] Further, the lower air outlet duct 23 includes a main air duct wall 231 and a lower air outlet wall, both of which correspond to the rear side wall 13, and the lower air outlet wall is arranged close to the front lower air outlet 122; the lower air outlet wall includes an arcuate wall section 232 and a straight wall section 233, the arcuate wall section 232 protrudes in a direction away from the front side wall 12 and the arcuate wall section 232 connects the main air duct wall 231 and the straight wall section 233; the straight wall section 233 is inclined relative to the horizontal plane, and the inclination angle of the straight wall section 233 relative to the horizontal plane is γ, which satisfies: 0°≤γ≤5°;

[0104] Through the inclination angle design of the straight wall section 233, the air outlet direction can be accurately controlled, thereby improving the air supply comfort of the whole machine; the front lower air outlet 122 is all hidden, thereby improving the aesthetics of the whole machine; the design of the arc-shaped wall section 232 has a buffering effect on the air in the lower air outlet duct 23, reduces the pressure loss caused by structural mutation, and guides the air in the lower air outlet duct 23.

[0105] In addition, the cabinet air conditioner further includes a grille 34, which is arranged in the lower air outlet 23 and close to the front lower air outlet 122; the grille 34 includes a grille frame 341 and grille bars 342, the grille frame 341 is an arc-shaped structure, and a plurality of grille bars 342 are provided, and the plurality of grille bars 342 are sequentially spaced along the extension direction of the grille frame 341; the grille bars 342 have the functions of lifting and gathering air, so that hot air is not blown to the ground and air is aggregated, thereby avoiding heat loss;

[0106] The arc-shaped structure of the grille frame 341 is adapted to the rotation path of the front lower air guide plate 33. On the one hand, it utilizes the space to provide rotation space for the front lower air guide plate 33. On the other hand, it guides and aggregates the air in the lower air outlet duct 23, achieving the wind lifting effect and the uniform air flow field, so that the air does not blow on the ground and avoids heat loss.

[0107] To summarize, the cabinet air conditioner proposed in this embodiment has three hidden air outlets, which take into account the zoned air supply for cooling and heating and the beautification of the appearance; the three air guide mechanisms can be controlled separately, and any one of the three air outlets can be opened separately, any two can be opened, or all three can be opened at the same time to achieve different air supply directions and different air supply distances; the air guide mechanism is controlled to open or close the corresponding air outlet, or the air outlet direction of the corresponding air outlet is adjusted, so that only the top air outlet 111 can be used for air outlet, only the upper front air outlet 121 can be used for air outlet, only the top air outlet 111 and the lower front air outlet 122 can be used for air outlet, only the upper front air outlet 121 and the lower front air outlet 122 can be used for air outlet, and three air outlets can be used for air outlet at the same time; with a variety of air outlet modes, multi-directional and multi-dimensional air supply can be achieved, the air supply volume is increased, and the diverse needs of users are met.

Users can choose a more energy-saving and comfortable air outlet method according to actual needs.

[0130] Specifically, Figure 6a This is a flow chart of an embodiment of a control method for a cabinet air conditioner in a cooling mode, specifically:

[0131] Step 1: Turn on the cabinet air conditioner;

[0132] Step 2: The user selects a cooling mode;

[0133] Step 3, the user determines whether to select the sweeping air mode; if the sweeping air mode is selected, the user customizes the air outlet mode and turns on the sweeping air mode; the default is up and down air outlet and up and down sweeping air; if the sweeping air mode is not selected, proceed to the next step;

[0134] Step 4, detecting the current temperature Te in the room, and calculating the temperature difference ΔT=Te-T between the current temperature Te and the preset temperature T set by the user;

[0135] Step 5, determine whether ΔT is greater than or equal to the preset temperature difference; if so, the user continues to determine whether to select rapid cooling according to demand; if rapid cooling is selected, the top air guide plate 31 is controlled to rotate and the top air outlet 111 is opened, the front lower air guide plate 33 is controlled to rotate and the front lower air outlet 122 is opened, and the inclination angle of the top air guide plate 31 and the inclination angle of the front lower air guide plate 33 are both set to the first grid, so as to achieve "rapid cooling without blowing cold wind on people"; specifically, the inclination angle of the top air guide plate 31 and the inclination angle of the front lower air guide plate 33 are both set to five grids, and the inclination angle of the top air guide plate 31 and the inclination angle of the front lower air guide plate 33 are the smallest when they are the first grid, and the inclination angle of the top air guide plate 31 and the inclination angle of the front lower air guide plate 33 are the largest when they are the fifth grid; the preset temperature difference is 5°C;

[0136] Step 6: If rapid cooling is not selected, the user determines whether the maximum air supply volume is required; if necessary, all three air outlets are opened, the top air guide plate 31 is adjusted to the fifth grid, the front upper air guide plate 32 is adjusted to the set angle (5°≤α≤15°, the best design parameter α≤10° in this embodiment, the gap is used to suck in external air to increase the air supply volume), and the wind gear of the fan blade 24 is adjusted to the super gear to achieve the maximum air supply volume;

[0137] If not needed, the user customizes the number of grids of the top air guide plate 31, the upper front air guide plate 32 and the lower front air guide plate 33, and selects the upper air outlet mode (opening the top air outlet 111, and closing the upper front air outlet 121 and the lower front air outlet 122), the upper and lower air outlet mode (opening the top air outlet 111 and the lower front air outlet 122, and closing the upper front air outlet 121) and the wind avoidance mode (upper air outlet mode, upper and lower air outlet mode) according to needs.

[0138] Figure 6b This is a flow chart of an embodiment of a control method for a cabinet air conditioner in a heating mode, specifically:

[0139] Step 1: Turn on the cabinet air conditioner;

[0140] Step 2: The user selects a heating mode;

[0141] Step 3: The user determines whether to select the sweeping air mode. If the sweeping air mode is selected, the user customizes the air outlet mode and turns on the sweeping air mode. The default is up and down air outlet and up and down sweeping air. If the sweeping air mode is not selected, proceed to the next step.

[0142] Step 4: Detect the current temperature Te in the room, and calculate the temperature difference ΔT=T-Te between the current temperature Te and the preset temperature T set by the user;

[0143] Step 5, determine whether ΔT is greater than or equal to 5°C; if so, the user continues to determine whether to select rapid heating according to demand; if rapid heating is selected, the front upper air outlet 121 is opened to the default position and the front lower air outlet 122 is opened, the front upper air outlet 121 presses the hot air and the front lower air outlet 122 raises the air, so as to achieve "rapid heating";

[0144] Step 6. If rapid heating is not selected, the user customizes the adjustment of the inclination angle of the top air guide plate 31, the inclination angle of the upper front air guide plate 32 and the inclination angle of the lower front air guide plate 33 (different air guide plate angles are designed according to the program), and selects the upper air outlet mode (opening the top air outlet 111, closing the upper front air outlet 121 and the lower front air outlet 122) and the upper and lower simultaneous air outlet mode (opening the top air outlet 111 and the lower front air outlet 122, and closing the upper front air outlet 121) according to needs.
