When the vertical air conditioner in this application is running, the user can open the first air outlet 4 and the second air outlet 311 according to needs, for example, when the air conditioner is in cooling mode, only the first air outlet 4 can be opened , so that the cold air enters the upper space of the room, avoiding the cold air directly blowing to the human body, and increasing the comfort; when the air conditioner is in the heating mode, the first air outlet 4 and the second air outlet 311 can be opened at the same time, so that the room The room can be quickly heated, or only the second air outlet 311 is opened, so that the hot air can be blown to the legs and feet, and the temperature in the room rises as the hot air rises, which can also increase the comfort.

When the vertical air conditioner in the present application is installed, the air intake panel 26 is connected to the chassis 3 through a bolt and fixed with screws; the base 29 is connected to the chassis 3 through a bolt, and the two sides of the base 29 are connected On the air inlet panel 26, the base 29, the chassis 3 and the air inlet panel are fixed together by screws to form a stable skeleton. The heat exchanger 20 is connected to the air inlet panel 26 through a buckle, and its bottom end is directly placed on the base 29, and fixed to the air inlet panel 26 by screws. A plurality of volute fans 231 are assembled on the mounting plate 25 through bolts, and are fixed together by screws. The assembled volute fans 231 and the mounting plate 25 form an air duct component, and then the entire air duct component is fixed with the air inlet panel 26 by screws, and the bottom end is placed on the base 29, which is also fixed by screws. The top cover assembly 1 is assembled to the upper end of the air inlet panel 26 through front and rear direction bolts, and fixed with screws, wherein the top cover assembly 1 can be lifted up and down to open and close the first air outlet 4, as shown in Figure 2 and Figure 13, wherein Figure 2 In Fig. 13, the first air outlet 4 is in an open state, and in Fig. 13 , the first air outlet 4 is in a closed state. The windshield 28 is assembled on the mounting base 200 by buckling, and fixed with the wind inlet panel 26 by screws. Among them, the windshield 28 is used for the heat preservation of the ventilation aisle. Because the temperature of the wind inside is different from that of the outside, it is easy to generate condensation on the front panel 27. This windshield 28 is used to separate them and prevent the body from generating Condensation. The front panel 27 is hung on the air inlet panel 26 through buckles, and the inner side is fixed with the air inlet panel 26 using screws.

When the air conditioner is started, the top cover 11 in the top cover assembly 1 rises upwards to open the first air outlet 4, and the rotating drive part 33 in the chassis 3 drives the casing 32 to rotate, and the casing 32 is rotated to The air outlet grille 321 is located at the front side and corresponding to the second air outlet 311 , so as to open the second air outlet 311 . Then, three groups of volute blowers 231 start immediately, and the wind on the air inlet panel 26 side passes through the air inlet 21, flows through the heat exchanger 20, and after exchanging heat through the heat exchanger, the cold/hot air is sucked into the volute fans 231, and then The wind blades in the volute blower 231 are thrown to the outlets 2311 of the three volutes. Wherein, the wind passing through the upper volute fan flows directly to the first air outlet 4 through the upper air channel 222, the wind of the lower volute fan flows to the second air outlet 311 through the lower air channel 221, and the wind of the middle volute fan Part of the wind flows to the first air outlet 4 through the sealed air passage between the mounting plate 25 and the windshield 28 , and part of it flows to the second air outlet 311 through the channel formed by the base 29 and the chassis 3 . The wind from the first air outlet 4 is composed of the wind from the upper volute and the middle volute, which is guided to the outside by the guide of the top cover assembly 1, and the wind from the second air outlet 311 is composed of the wind from the lower volute and the middle volute , the chassis 3 guides the air to the outside, so as to realize the simultaneous air outlet from the top and bottom of the air conditioner.

When the second air outlet 311 is opened and the first air outlet 4 is closed (the top cover 11 moves to the lowest position under the drive of the drive mechanism 12 at this time), the wind flowing to the first air outlet 4 is on the top cover 11. Change the flow direction under the action, flow to the second air outlet 311 through the reversing air duct 223, and all the wind is blown out by the second air outlet 311, so that only the air is discharged from the bottom of the air conditioner; when the second air outlet 311 When the first air outlet 4 is opened (the top cover 11 moves to the uppermost position under the drive of the drive mechanism 12), at this time, the air duct baffle 34 is in the closed position, and flows to the second air outlet. The wind of 311 changes the flow direction under the action of the air duct baffle 34, flows to the first air outlet 4 through the reversing air duct 223, and all the wind is blown out by the first air outlet 4, realizing that only the air conditioner wind from the top.

In the present application, a windshield 28 is arranged on the inner side of the front panel 27, and an air insulation layer 278 is formed between the windshield 28 and the front panel 27, which can effectively prevent the occurrence of Condensed water improves user experience.

The vertical air conditioner in the present application can realize simultaneous air outlet up and down, and also can realize air outlet only from the upper part or only from the lower part. Through the change of the internal wind flow direction, only the upper part or only the lower part of the air is realized. When only the upper part or only the lower part of the air is blown out, the air flow will not be reduced. It can meet the needs of different parts of the wind while retaining a certain amount of air flow to achieve fast. The temperature can be adjusted, and the air flow can be adjusted by adjusting the size of the upper and lower air outlets, and the adjustment range is relatively wide.

When the vertical air conditioner in the present application is in the closed state, the top cover in the top cover assembly descends to block the top opening 24, and at the same time, the casing 32 closes the second air outlet 311, which can make this Viewed from the front side, the vertical air conditioner under application has no openings in appearance and has a more complete appearance (as shown in Figure 7), which can effectively improve the appearance integrity of the vertical air conditioner. At the same time, it can prevent dust and debris from entering the vertical air conditioner, improve the use environment of the air conditioner, and prolong the service life of the air conditioner.

In the vertical air conditioner of the present application, the main air duct 22 runs through the entire longitudinal direction of the air conditioner, so that the first air outlet 4 and the second air outlet 311 can be located at the upper and lower ends of the air conditioner, so that the cold wind can flow from as high a position as possible. Blowing out, the hot air can be blown out from the lowest possible position, effectively improving the comfort of the air conditioner, and at the same time making the longitudinal dimension of the heat exchanger as large as possible to improve the heat transfer performance of the air conditioner.

In a word, the vertical air conditioner in this application has a simple and compact structure, is convenient to install and use, has a neat and beautiful appearance, and can meet various needs of users.
