[0035] The air outlet design of floor-standing air conditioners on the market involves internal louvers and a door at the air outlet. The door opens and closes to deliver air; the internal air passes through the inner louvers and then through the door to be expelled to the outside. This type of air conditioner has a relatively short air delivery distance at the terminal, and the temperature difference between each layer of air at the terminal is relatively large. Therefore, this application designs an air conditioner with a longer air delivery distance at the terminal and a smaller temperature difference.

[0036] Please refer to Figures 1 to 5 As shown in the figure, an embodiment of this application provides an air conditioner 100, including a housing 10 and a wind deflector assembly 20. The housing 10 has an air outlet 11 extending downwards. The wind deflector assembly 20 is rotatably disposed at the air outlet 11. The wind deflector assembly 20 includes a plurality of external louvers 21 and a wind deflector 22. The wind deflector 22 is rotatably disposed at the air outlet 11 to close and open the air outlet 11, allowing the interior of the air conditioner 100 to be supplied to the outside. When the air outlet 11 is opened, the wind deflector 22 extends to the outside of the air outlet 11.

[0037] Specifically, the air conditioner 100 of this application is a vertical air conditioner 100, which includes a housing 10 and a wind deflector assembly 20. The housing 10 has an air outlet 11 extending from top to bottom, that is, the air outlet 11 is vertically arranged, and the wind deflector assembly 20 is also vertically arranged. The wind deflector assembly 20 is rotatably arranged at the air outlet 11 to open and close the air outlet 11.

[0038] like Figure 6 and Figure 7As shown, the wind deflector assembly 20 includes a wind deflector 22 and multiple outer louvers 21, which are arranged at intervals in the vertical direction. The outer louvers 21 rotate synchronously with the wind deflector 22. When the wind deflector 22 rotates at the air outlet 11, it drives the outer louvers 21 to rotate synchronously, so that the outer louvers 21 extend out of the air outlet 11. When the wind deflector 22 closes the air outlet 11, it blocks the air outlet 11; when the wind deflector 22 opens the air outlet 11, it extends to the outside of the air outlet 11, thereby increasing the distance of the air outlet at the end of the air conditioner 100. Because multiple outer louvers 21 are also provided in the vertical direction of the wind deflector 22, the temperature difference between each layer at the end of the air conditioner 100 is smaller, thus improving the comfort of the air outlet of the air conditioner 100.

[0039] Please refer to Figures 3 to 5 As shown, in an optional embodiment, the wind deflector assembly 20 includes a first wind deflector assembly 20a and a second wind deflector assembly 20b, and the air outlet 11 includes a first air outlet 11a and a second air outlet 11b. The first air outlet 11a and the second air outlet 11b are disposed on the left and right sides of the housing 10. The air conditioner 100 can exhaust air from the left and right sides of the housing 10, and the air sweeping method is left and right sweeping.

[0040] The air conditioner 100 also includes a fan wheel 30, which is disposed inside the housing 10. The housing 10 also has a main air duct 12 and two branch air ducts 13 that are connected to each other. Air outlets 11 are disposed at the ends of the branch air ducts 13, that is, the first air outlet 11a and the second air outlet 11b are respectively disposed on the left and right sides of the two branch air ducts 13. Specifically, the air conditioner 100 of this application is a single-flow vertical air conditioner 100, in which the main air duct 12 and two branch air ducts 13 are formed inside the housing 10. The starting position of the main air duct 12 is located close to the fan wheel 30, and it is used to receive the air generated by the fan wheel 30. Both branch air ducts 13 connect to the main air duct 12, and extend to the air outlets 11 (11a, 11b) on the left and right sides of the housing 10 to deliver the air generated by the impeller 30 to the air outlets 11 (11a, 11b); subsequently, the baffle plate 22 opens the air outlets 11 (11a, 11b) to allow air to be delivered to the outside. Figure 5 As shown, when the baffle plate 22 rotates 45°, the baffle plate 22 faces the front of the housing 10, so that the air from the impeller 30 can be directed to the front of the air conditioner 100, thus solving the problem of dead airflow at the front of dual-outlet air conditioners 100 on the market.

[0041] In an optional embodiment, the included angle between the two split air ducts 13 is in the range of 90°-130°. The housing 10 also includes a volute tongue 14 and a volute plate 15, with one of the split air ducts 13 located in the direction in which the volute tongue 14 extends. Specifically, the two split air ducts 13 are a left air duct 131 and a right air duct 132. The housing 10 contains a volute plate 15 and a volute tongue 14. The volute tongue 14 is located near the impeller 30. The left air duct 131 is positioned in the direction in which the volute tongue 14 extends. The included angle between the right air duct 132 and the left air duct 131 is in the range of 90°-130°. This application utilizes dual air outlets 11, resulting in a large air outlet angle, high high-temperature efficiency of the air conditioner 100, and more uniform airflow, thus improving the user experience.

[0042] Please refer to Figure 5 As shown, a diverter 40 is also provided at the junction of the two diverter ducts 13. The diverter 40 is used to control the airflow of the two diverter ducts 13. Specifically, a diverter 40 is provided at the junction of the left duct 131, the right duct 132 and the main duct 12. The diverter 40 extends towards the left duct 131 to intercept part of the airflow at the left duct 131, so that the airflow of the left duct 131 and the right duct 132 is approximately the same, thereby improving the uniformity of the airflow from the two diverter ducts 13. It should be noted that the left duct 131 is located in the direction of the extension of the volute tongue 14, so most of the air delivered by the main duct 12 will flow to the left duct 131. The diverter 40 is provided to make the airflow of the left duct 131 and the right duct 132 the same.

[0043] The air conditioner 100 also includes inner louvers 50 disposed inside the housing. The inner louvers 50 extend into the main air duct 12 and the two branch air ducts 13, and the branching component 40 is integrally disposed on the inner louvers 50. Specifically, the inner louvers 50 are also disposed inside the housing 10 and are disposed in the air duct. The inner louvers 50 are disposed so that the temperature difference of each layer of the initial air outlet of the air conditioner 100 is small. After being branched by the left air duct 131 and the right air duct 132, the air passes through the air guide plate and the outer louvers 21 on the air guide plate, so that the temperature difference of each layer of the terminal air outlet of the air conditioner 100 is small. Therefore, the air conditioner 100 of this application has better air outlet effect and higher comfort.

[0044] Please refer to Figure 9As shown, in an optional embodiment, the wind deflector 22 includes a main body plate 221 and two connecting arms 222, which are respectively disposed at the upper and lower ends of the main body plate 221. One connecting arm 222 is drivenly connected to a motor, and the other connecting arm 222 is rotatably connected to the housing 10. Specifically, the wind deflector 22 includes a vertically arranged main body plate 221 and two connecting arms 222, with one connecting arm 222 disposed at the upper end of the main body plate 221 and the other connecting arm 222 disposed at the lower end of the main body plate 221. The air conditioner 100 also includes a motor, which is installed inside the housing 10 and provides power for the rotation of the wind deflector 22. The connecting arm 222 at the upper end of the main body plate 221 is drivenly connected to the motor, the lower end of the main body plate 221 is connected to the housing 10, and the main body plate 221 can rotate relative to the housing 10. It should be noted that the motor can also be located at the lower end of the main body plate 221 and connected to the connecting arm 222 at the lower end of the main body plate 221 for transmission, while the connecting arm 222 at the upper end of the main body plate 221 is rotatably connected to the housing 10.

[0045] Please refer to Figure 9 and Figure 10 As shown, the wind deflector 22 also includes multiple locking posts 223 disposed on the main body plate 221, and the housing 10 includes multiple locking slots 16 adapted to the locking posts 223. Specifically, the wind deflector 22 is further provided with multiple locking posts 223 at intervals in the vertical direction, and a locking slot 16 is provided on the housing 10 at a position corresponding to each locking post 223. The locking posts 223 are engaged in the locking slots 16, and can rotate in the locking slots 16 when the wind deflector 22 rotates. Because the wind deflector 22 is relatively long, it will vibrate when the motor drives it to rotate. In order to reduce the degree of vibration when the wind deflector 22 rotates, multiple locking posts 223 are also provided in the vertical direction of the main body plate 221.

[0046] Please refer to Figure 9 As shown, the inner surface 2211 of the main body plate 221 is an arc-shaped surface. Specifically, when the baffle plate 22 rotates, it opens and closes the air outlet 11. The inner surface 2211 of the main body plate 221 is an arc-shaped air guiding surface. Setting the inner surface 2211 of the main body plate 221 to be arc-shaped increases the length of the air guiding at the end of the air conditioner, thereby increasing the air guiding distance at the end of the air conditioner 100.

[0047] Please refer to Figure 3As shown, one side of the main body panel 221 overlaps the outside of the air outlet 11, while the other side extends into the air outlet 11. Specifically, one side of the main body panel 221 is provided with an extension 224, and the corresponding side of the air outlet 11 is provided with a baffle portion 111. The extension 224 is located inside the baffle portion 111, so that this side of the main body panel 221 has no openings. The other side of the main body panel 221 overlaps the outside of the air outlet 11, and a chamfer can be provided on the outer wall of the air outlet 11 for the left side of the main body panel 221 to overlap. When the air outlet 11 is closed, one side of the main body panel 221 extends into the interior, while the other side overlaps the outside of the air outlet 11, so that when viewed from the front of the air conditioner 100, the air conditioner 100 does not appear to have any dark openings, thus improving the aesthetics of the air conditioner 100.

[0048] Please refer to Figure 8 As shown, the outer louver 21 includes a main blade 211, a second insertion part 212, and a first insertion part 213 connected together. The wind deflector assembly 20 also includes a connecting rod disposed on the main body plate 221. The first insertion part 213 is inserted into the wind deflector plate 22, and the second insertion part 212 is inserted into the connecting rod. Specifically, the outer louver 21 is an integrally formed structural component, such as being integrally injection molded. The outer louver 21 includes a main blade 211, a first insertion part 213, and a second insertion part 212. A connecting rod is also provided on the main body plate 221. The first insertion part 213 has a mushroom head structure, and the wind deflector plate 22 is provided with an insertion groove adapted to the mushroom head structure to facilitate the insertion of the outer louver 21 onto the wind deflector plate 22. This application improves the stability of the outer louver 21 by using the first insertion part 213 and the second insertion part 212 to install the main blade 211 onto the wind deflector plate 22.

[0049] Please refer to this again. Figures 3 to 5 As shown, in an optional embodiment, the diversion duct 13 has a duct wall 133, the portion of which near the air outlet 11 is concave. Specifically, the duct wall of the diversion duct is the side wall of the diversion duct. The concave shape of the portion of the duct wall 133 near the air outlet 11 facilitates the rotation of the baffle plate 22 within the air outlet 11. The baffle assembly 20 of this application needs to open the air outlet 11 and extend to the outside of the air outlet 11 when rotating, so that the baffle plate 22 can play a guiding role. The baffle plate 22 is relatively large, therefore the width of the portion of the duct wall 133 near the air outlet is also set to be relatively wide, and when the baffle plate 22 rotates to the maximum air outlet angle, the actual air outlet channel formed between the baffle plate 22 and the other side of the air outlet 11 is approximately the same as the width of the diversion duct 13.

[0050] It should be noted that the air conditioner 100 of this application also includes an evaporator 60 and an air outlet frame 70 disposed inside the housing 10. The housing 10 includes a rear housing assembly 17, a panel support assembly 18, and a panel 19. The panel is disposed in front of the panel support assembly, and the first air deflector assembly 20a and the second air deflector assembly 20b are disposed on the left and right sides of the panel.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
