With the above arrangement, the plurality of branch air ducts 11 are connected to form a main air duct 1, and each branch air duct 11 is provided with a fan 2, and the fan can blow the airflow in the branch air duct 11 to the main air duct 1. A baffle assembly 3 is arranged in the main air duct 1, and at least a part of the baffle assembly 3 is movably arranged, so that the main air duct 1 can switch its state and choose to be connected with different branch air ducts 11, or cut off the connection with different channels. In this way, a changeable airflow passage is formed in the air duct structure, so that the airflow can flow out from different parts of the air conditioner, solving the problem of the relatively single air outlet mode of the air conditioner in the prior art.

[0042] In the air duct structure of the present embodiment, the multiple branch air ducts 11 include a first branch air duct 111 and a second branch air duct 112, and the baffle assembly 3 includes a first baffle 31 and a second baffle 32 arranged between the first branch air duct 111 and the second branch air duct 112; the first baffle 31 has a first dividing position for separating the first branch air duct 111 and the second branch air duct 112 and a first partition position for partitioning the first branch air duct 111 into two air duct sections, and the second baffle 32 has a second dividing position for separating the first branch air duct 111 and the second branch air duct 112 and a second partition position for partitioning the second branch air duct 112 into two air duct sections.

[0043] With the above arrangement, the first branch air duct 111 and the second branch air duct 112 form a main air duct 1 , and the first baffle plate 31 and the second baffle plate 32 are between the first branch air duct 111 and the second branch air duct 112 .

[0044] In the air duct structure of this embodiment, the outlet of the first branch air duct 111 is located below the outlet of the second branch air duct 112. The first branch air duct 111 can be divided into two air duct sections by adjusting the posture of the first baffle 31. The second branch air duct 112 can be divided into two air duct sections by adjusting the posture of the second baffle 32. The first branch air duct 111 and the second branch air duct 112 are partially connected to form a new air flow channel, thereby providing more ways for the flow of air.

[0045] like Figure 1 As shown, in the air duct structure of this embodiment, the outlet of the first branch air duct 111 is arranged in a horizontal direction, and / or the outlet of the second branch air duct 112 is arranged upward to meet the air outlet demand of the air conditioner.

[0046] In the air duct structure of this embodiment, Figure 1 As shown, the inlet of the first branch air duct 111 is located above the inlet of the second branch air duct 112. In this way, the air duct structure can collect air from different positions.

[0047] In the air duct structure of this embodiment, the air duct structure also includes the following states:

When the air duct structure is in the first air outlet state, the first baffle 31 is in the first separation position, the second baffle 32 is in the second separation position, the fan 2 in the first branch air duct 111 is in a stopped state, and the fan 2 in the second branch air duct 112 is in a started state. At this time, the air duct structure is in a state where the airflow enters from the bottom and exits from the top.

When the air duct structure is in the fifth air outlet state, the first baffle 31 is in the first partition position, the second baffle 32 is in the second partition position, the fan 2 in the first branch air duct 111 is in the start state, and the fan 2 in the second branch air duct 112 is in the start state. At this time, the air duct structure is in a state of strong wind in the airflow.

[0053] like Fig. 9 As shown, the air duct structure has a sixth air outlet state. When the air duct structure is in the fifth air outlet state, the first baffle 31 is in the first partition position, the second baffle 32 is in the second partition position, the fan 2 in the first branch air duct 111 is in the start-up state, and the fan 2 in the second branch air duct 112 is in the start-up state. At this time, the air duct structure is in a state of strong wind in the airflow.

[0054] like Figure 12 to Figure 14 As shown, in order to improve the performance of the air duct structure, in the air duct structure of this embodiment, the air duct structure also includes: a fresh air duct 4, the fresh air duct 4 has a fresh air inlet 41 and a fresh air outlet, so that the fresh air flowing out of the fresh air duct 4 enters at least one branch air duct 11 among the multiple branch air ducts 11.

[0055] The fresh air duct 4 in this embodiment can filter, disinfect and other processes the airflow entering the duct structure, thereby improving the quality of the air entering the duct structure.

[0056] like Figure 12 to Figure 14As shown, in order to purify the airflow entering the air duct structure, a primary filter component 42 and a secondary filter component 43 are provided on the fresh air duct 4, and the primary filter component 42 and the secondary filter component 43 are arranged along the fresh air flow direction of the fresh air duct 4. By providing the primary filter component 42 and the secondary filter component 43, the airflow entering the air duct structure can be filtered, disinfected, etc.

[0057] In the air conditioner of this embodiment, Figures 1 to 14 As shown, it includes: a casing 6, on which are arranged a plurality of air inlets 61 and a plurality of air outlets 62; as in the air duct structure described above, the plurality of air inlets 61 are arranged one-to-one correspondingly with the inlets of the plurality of branch air ducts 11 of the air duct structure, and the plurality of air outlets 62 are arranged one-to-one correspondingly with the outlets of the plurality of branch air ducts 11.

[0058] In the air conditioner of this embodiment, the casing 6 includes a front panel 63 and a rear panel 64 that are arranged opposite to each other, a plurality of air inlets 61 are arranged on the rear panel 64 at intervals in the vertical direction, and a plurality of air outlets 62 are arranged at intervals in the vertical direction.

[0059] In the air conditioner of this embodiment, the housing 6 includes a top plate 65 , at least one of the plurality of air outlets 62 is disposed on the top plate 65 , and at least one of the plurality of air outlets 62 is disposed on the front panel 63 .

[0060] In the air conditioner of this embodiment, the air conditioner further includes: a heat exchanger 5, the heat exchanger 5 extends in the vertical direction, the heat exchanger 5 is arranged opposite to the rear panel 64 of the casing 6, and a plurality of air outlets 62 are arranged on the rear panel 64. By arranging the heat exchanger, the airflow entering the air conditioner is heat exchanged to form hot air or cold air.

[0061] like Fig.11 As shown, in the air conditioner of this embodiment, the air duct structure is the above-mentioned air duct structure, and the casing 6 is provided with a fresh air inlet 66 for communicating with the fresh air inlet 41 of the fresh air duct 4.

[0062] In the air conditioner of this embodiment, the air duct structure is an air duct structure, and the housing 6 is provided with a fresh air inlet 66 for communicating with the fresh air inlet 41 of the fresh air duct 4. The airflow enters the fresh air duct 4 through the fresh air inlet 66 and the fresh air inlet 41.

[0063] The main control method of the air conditioner of this embodiment is as follows:

[0064] In the air conditioner of this embodiment, there is an air outlet 62 on the front wall of the casing 6, and the air outlet 62 is a lower air outlet. There is an air outlet 62 on the top wall of the casing 6, and the air outlet 62 is an upper air outlet. There are two upper and lower air inlets 61 and an outdoor fresh air inlet 66 on the rear wall of the casing 6.

[0065] The air conditioner of this embodiment is composed of two parts: a main air duct assembly and a fresh air assembly. The main air duct assembly includes a main air duct 1, a heat exchanger 5, a baffle assembly 3 and a centrifugal fan (fan 2) assembly. The evaporator is located at the fan inlet and is placed vertically up and down. The centrifugal fan assembly includes an upper centrifugal fan and a lower centrifugal fan. The upper centrifugal fan is connected to the upper air inlet 61 to realize the upper air inlet mode, and the lower centrifugal fan is connected to the lower air inlet 61 to realize the lower air inlet mode. The fresh air assembly is located below the main air duct assembly. The fresh air assembly includes a fresh air duct 4, a coarse filter (a primary filter component 42) and a fine filter (a secondary filter component 43). The coarse filter is used to filter large particles in the air flow, and the fine filter further filters the filtered air to purify the outdoor air and flow it into the room.

[0066] Reference Figure 3 It can be concluded that when the lower centrifugal fan is running, indoor air flows in from the lower air inlet 61, passes through the heat exchanger 5, enters the fan, flows into the main air duct 1, and is finally discharged from the upper air outlet 62, realizing a lower air inlet and upper air outlet mode.

[0067] Reference Fig. 9 It can be concluded that when the upper centrifugal fan is running, indoor air flows in from the upper air inlet 61, passes through the heat exchanger 5, enters the fan, flows into the main air duct 1, and is finally discharged from the lower air outlet 62, realizing an upper air inlet and lower air outlet mode.

[0068] See attached Figure 6 It can be seen that when the baffle assembly 3 rotates to the position shown in the figure and the lower centrifugal fan is running, the indoor air flows in from the lower air inlet 61, passes through the heat exchanger 5, enters the fan, flows into the main air duct 1, and is finally discharged from the lower air outlet 62, realizing the lower air inlet and lower air outlet mode.

[0069] See attached Figure 7 It can be seen that when the baffle assembly 3 rotates to the position shown in the figure and the upper centrifugal fan is running, the indoor air flows in from the upper air inlet 61, passes through the heat exchanger 5, enters the fan, flows into the main air duct 1, and is finally discharged from the lower air outlet 62, realizing the upper air inlet and upper air outlet mode.

[0070] See attached Figure 8 It can be seen that when the baffle assembly 3 rotates to the position shown in the figure and the upper centrifugal fan and the lower centrifugal fan are running at the same time, the indoor air flows in from the lower air inlet 61 and the upper air inlet 61 at the same time, passes through the heat exchanger 5, and the airflows of the lower centrifugal fan and the upper centrifugal fan flow out from the upper air outlet 62 at the same time, realizing the upper air outlet strong wind mode.

[0071] See attached Fig. 9It can be seen that when the baffle assembly 3 rotates to the position shown in the figure and the upper centrifugal fan and the lower centrifugal fan are running at the same time, the indoor air flows in from the lower air inlet 61 and the upper air inlet 61 at the same time, passes through the heat exchanger 5, and the outflow air of the lower centrifugal fan and the upper centrifugal fan flows out from the lower air outlet 62 at the same time, realizing the lower air outlet strong wind mode.

[0072] When outdoor air enters the fresh air duct 4 through the fresh air inlet 66, it passes through the filter and flows into the fan 2 through the heat exchanger 5 to realize the fresh air mode. The fresh air can be mixed with the airflow of the main air duct 1, or the fresh air mode can be realized alone. When the upper air inlet 61, the lower air inlet 61 and the fresh air inlet 66 are opened at the same time, the fresh air can be mixed with the airflow of the main air duct; when the upper air inlet 61 and the lower air inlet 61 are closed and the fresh air inlet 66 is opened, the fresh air mode can be realized alone.

[0073] From the above description, it can be seen that the air duct structure includes: a main air duct 1, multiple fans 2, and a baffle assembly 3. The main air duct 1 has multiple branch air ducts 11, and the multiple branch air ducts 11 are used to communicate with multiple air outlets 62 in a one-to-one correspondence; multiple fans 2 are arranged in multiple branch air ducts 11 in a one-to-one correspondence; the baffle assembly 3 is arranged in the main air duct 1, and at least part of the baffle assembly 3 is movably arranged to make the multiple branch air ducts 11 independent of each other, or to make at least two of the multiple branch air ducts 11 communicate with each other. With the above arrangement, multiple branch air ducts 11 are connected to form a main air duct 1, and each branch air duct 11 is provided with a fan 2, which can blow the airflow in the branch air duct 11 to the main air duct 1. A baffle assembly 3 is arranged in the main air duct 1, and at least a part of the baffle assembly 3 is movably arranged, so that the main air duct 1 can switch its state and choose to be connected with different branch air ducts 11, or cut off the connection with different channels. In this way, a changeable airflow passage is formed in the air duct structure, so that the airflow can flow out from different parts of the air conditioner, solving the problem of the relatively single air outlet mode of the air conditioner in the prior art.

[0075] (1) Increase the air volume at the air outlet of the air conditioner;

[0076] (2) The air conditioner can realize two different air outlet modes through two centrifugal fans: upper air intake and lower air outlet for heating and lower air intake and upper air outlet for cooling, so that users can adjust the air supply mode according to their needs;
