When the middle air outlet 112 is in the open state, the middle air outlet baffle blocks between the first air duct section and the second air duct section, so that the airflow in the first air duct section flows out from the middle air outlet 112 under the stopping action of the middle air outlet baffle; when the middle air outlet 112 is in the closed state, the middle air outlet baffle blocks at the middle air outlet 112, so that the airflow in the first air duct section flows into the second air duct section.

[0054] Specifically, a fan component 20 is respectively arranged in the two ventilation ducts 11. The two fan components 20 are respectively an upper fan component and a lower fan component arranged up and down, and correspondingly, the first ventilation duct 14 and the second ventilation duct 15 are respectively an upper ventilation duct and a lower ventilation duct.

[0055] In this embodiment, if Figure 4As shown, the upper end of the first upper air duct section 141 forms a first upper air outlet 241, the lower end of the first lower air duct section 142 forms a first lower air outlet 242, the upper end of the second upper air duct section 151 forms a second upper air outlet 251, and the lower end of the second lower air duct section 152 forms a second lower air outlet 252; wherein, the air duct structure includes an upper air outlet baffle 30 and a lower air outlet baffle 40, the upper air outlet baffle 30 is arranged at the second upper air outlet 251 to open or close the second upper air outlet 251; the lower air outlet baffle 40 is arranged at the first lower air outlet 242 to open or close the first lower air outlet 242.

[0057] Specifically, there are multiple middle air outlets 112, and the multiple middle air outlets include a first middle air outlet 133 and a second middle air outlet 134 arranged on the wind shield, the first middle air outlet 133 is connected to the first upper air duct section 141 and / or the first lower air duct section 142, and the second middle air outlet 134 is connected to the second upper air duct section 151 and / or the second lower air duct section 152; the air duct structure also includes a first middle air outlet baffle 50 and a second middle air outlet baffle 60, the first middle air outlet baffle 50 is arranged at the first middle air outlet 133 to open or close the first middle air outlet 133; the second middle air outlet baffle 60 is arranged at the second middle air outlet 134 to open or close the second middle air outlet 134.

[0058] It can be seen that the first central air outlet 133 and the second central air outlet 134 are both central air outlets, and the first central air outlet baffle 50 and the second central air outlet baffle 60 are both central air outlet baffles for shielding the corresponding central air outlet 112 .

[0059] The air duct structure in this embodiment has multiple air outlet modes. At least one fan component 20 is disposed in each of the first ventilation duct 14 and the second ventilation duct 15. The air outlet mode of the air duct structure includes at least one of the following air outlet modes:

[0060] Double down air outlet mode: when the air duct structure is in the double down air outlet mode, the fan components 20 in the first ventilation duct 14 and the second ventilation duct 15 are both in the down air outlet state, the first middle air outlet baffle 50 is in the closed state, and the second lower end air outlet 252 is in the open state;

[0061] Middle and lower air outlet mode, such as Fig.11As shown, when the air duct structure is in the middle and lower air outlet mode, the fan components 20 in the first ventilation duct 14 and the second ventilation duct 15 are both in the lower air outlet state, the first middle air outlet baffle 50 is in the open state, and the second lower air outlet 252 is in the open state;

[0062] Single down-flow mode, such as Fig.12 As shown, when the air duct structure is in the single downward air outlet mode, the fan component 20 in the first ventilation duct 14 is in a non-operating state, and the fan component 20 in the second ventilation duct 15 is in a downward air outlet state;

[0063] Double upper air outlet mode: when the air duct structure is in the double upper air outlet mode, the fan components 20 in the first ventilation duct 14 and the second ventilation duct 15 are both in the upper air outlet state, the second middle air outlet baffle 60 is in the closed state, and the second upper air outlet 251 is in the open state;

[0065] Single upper air outlet mode: when the air duct structure is in the single upper air outlet mode, the fan component 20 in the first ventilation duct 14 is in the upper air outlet state, and the fan component 20 in the second ventilation duct 15 is in the non-working state.

[0066] In addition, when the air duct structure is in the single downward air outlet mode, the first middle air outlet baffle 50 is closed and the lower end air outlet baffle 40 is closed. At this time, the first ventilation duct 14 does not blow air outward, that is, the fan component 20 in the first ventilation duct 14 is in a non-working state. At this time, the fan component 20 in the second ventilation duct 15 is in a downward air outlet state.

[0067] In order to control the upper air outlet state and the lower air outlet state of the fan component, the air duct structure also includes: a movable vortex tongue 70, which is arranged in the ventilation duct 11 and rotatably arranged around the fan component 20 to make the air flow in the fan component 20 flow toward the corresponding end air outlet 111.

[0068] For example, the movable vortex 70 includes an upper movable vortex and a lower movable vortex. When the upper movable vortex and the lower movable vortex are rotated to the side close to the second upper air outlet 251, the fan components 20 in the first ventilation duct 14 and the second ventilation duct 15 are both in the downward air outlet state.

[0069] Specifically, the fan component 20 has an upper air outlet and a lower air outlet. When the fan component 20 is in a working state (the fan component 20 rotates to drive the airflow), if the movable vortex tongue 70 blocks the upper air outlet, the fan component 20 is in a lower air outlet state, and if the movable vortex tongue 70 blocks the lower air outlet, the fan component 20 is in an upper air outlet state. If the fan component 20 is in a stopped state, it is in a non-working state.

[0070] The present invention also provides an air conditioner, including a casing 80 and a duct structure arranged in the casing 80, and the duct structure is the above-mentioned duct structure; the casing 80 includes a front panel 81 and a rear panel 82 arranged relatively to each other, and the front panel 81 is provided with a first air-conditioning outlet 811 connected to the end air outlet of the air duct structure and a second air-conditioning outlet 812 connected to the middle air outlet 112.

[0071] The present embodiment relates to a new type of air conditioner with multiple air outlet modes. The air conditioner mainly includes an air duct component and a wind shield component. The air duct system consists of two independent air ducts. Each of the two air ducts has an active volute tongue to enable the two air ducts to achieve single upper or single lower air outlet respectively. The wind shield component contains multiple active baffles. The airflow can be directed to the upper, middle and lower air outlets by opening and closing the baffles, thereby achieving six air outlet combinations such as "upper and lower air outlet", "middle air outlet", "single upper air outlet" and "single lower air outlet". The air outlet mode can be selected in combination with the working environment of the air conditioner and the user's wishes. While inheriting the advantages of the upper and lower distributed air supply system, it also solves the problem of uneven vertical temperature of indoor air during upper and lower distributed air supply.

[0072] In this embodiment, the upper air outlet baffle 30, the lower air outlet baffle 40, the first middle air outlet baffle 50, and the second middle air outlet baffle 60 are assembled on the wind shield 13 and can be independently controlled to be opened or closed.

[0073] The internal structure of the air duct structure in the present invention is as shown in the attached Fig.11 and 12 As shown, each ventilation duct includes two independent ducts, upper and lower. The upper duct has an upper air outlet and a lower air outlet, and the lower duct has an upper air outlet and a lower air outlet. There is a rotatable active volute tongue in each of the two ducts, and the two active volute tongues can move independently. The two volute tongues move to Figure 2 When in the middle position, the upper air duct discharges air downwards, and the lower air duct discharges air upwards. The upper and lower air ducts can discharge air upwards and downwards respectively according to the position of their respective volute tongues. The front view of the air duct components is as follows Figure 1 As shown, the upper air outlet of the upper air duct is located at the top of the air conditioner, the lower air outlet of the upper air duct and the upper air outlet of the lower air duct are located in the middle of the air conditioner, and the lower air outlet of the lower air duct is located at the bottom of the air conditioner.

The schematic diagram of the upper air outlet movable baffle (upper air outlet baffle 30) opening and closing is shown in FIG.

Figure 8 The movable baffle (upper air outlet baffle 30) in the air conditioner is in an open state, and the upper air outlet of the air conditioner exposes the upper air outlet (second upper air outlet 251) of the upper air duct of the air duct component and the upper air cavity (second upper air outlet 251) formed between the wind shield 13 and the volute assembly 12. The schematic diagram of the switch closing of the lower air outlet movable baffle (lower air outlet baffle 40) is shown in FIG. Fig. 9 As shown, Fig. 9 The movable baffle in the air conditioner is in a closed state, and the lower air outlet of the air conditioner only exposes the lower air outlet of the lower air duct of the volute assembly 12 (the second lower end air outlet 252). Fig.10 The movable baffle (lower end air outlet baffle 40) is in the open state, and the air conditioner exposes the lower air outlet of the lower air duct (the second lower end air outlet 252) and the lower air cavity (the first lower end air outlet 242) formed between the wind baffle and the volute assembly 12.

[0075] The schematic diagram of the opening and closing of the movable baffles (the first middle air outlet baffle 50 and the second middle air outlet baffle 60) of the middle air outlet (the middle air outlet 112) is shown in FIG. Figure 5 and Figure 6 As shown, Figure 5 The movable baffles in the Figure 6 The movable shutters in the system are all in the open position.

[0076] In this embodiment, by rotating the volute tongue in different positions, two upper air outlets can be simultaneously discharged, two lower air outlets can be simultaneously discharged, one upper air outlet and one lower air outlet can be simultaneously discharged, and two middle air outlets can be simultaneously discharged. With the wind shield and the movable baffle installed on the wind shield, the air conditioner can realize six air outlet modes, namely, single upper air outlet, single lower air outlet, middle air outlet, upper and lower air outlet, middle upper air outlet, and middle lower air outlet. When the middle movable baffle (the first middle air outlet baffle 50) is opened, the airflow of the upper air duct can be directed to the middle air outlet (the first middle air outlet) of the air conditioner, so as to realize the middle lower air outlet of the air conditioner. When the middle movable baffle (the first middle air outlet baffle 50) is closed and the lower air outlet movable baffle (the lower end air outlet baffle 40) is opened, the airflow is blown to the lower air outlet of the air conditioner along the lower air cavity formed between the wind shield and the air duct, and the airflows of the upper and lower air ducts are blown out from the lower air outlet of the air conditioner, so as to realize the single lower air outlet of the air conditioner.

[0077] The novel air conditioner designed in the present invention can adjust the temperature at the middle position of the room by blowing part of the air flow out from the middle air outlet. While inheriting the advantages of the vertical air conditioner with up and down air outlets, it also solves the problem of uneven indoor vertical temperature in the initial stage of cooling or heating of the vertical air conditioner with up and down air outlets, increases the diversity of the air outlet modes of the air conditioner, and increases the comfort of the air outlet of the air conditioner.
