[0037] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides a vertical air conditioner with increased exhaust volume, comprising a shell 1, a main air duct portion 2, a heat exchange portion 3 and an air supply assembly 4. The main air duct portion 2 is built into the bottom of the shell 1, and is used to inhale indoor air and transport it to the heat exchange portion 3. The heat exchange portion 3 is arranged above the air outlet of the main air duct portion 2, and is used to heat or cool the indoor air output by the main air duct portion 2. The air supply assembly 4 is arranged above the air outlet of the heat exchange portion 3, and is located at the top of the shell 1 close to the air outlet of the air conditioner (the air conditioner exhaust port is provided on the shell), and is used to concentrate the air after heat exchange, and can control the exhaust direction of the air.

[0038] For ease of explanation, the direction in which the vertical air conditioner exhausts air into the room is referred to as the front, and the position where the exhaust port is located is referred to as the top.

[0039] Specifically, such as Figure 3As shown, the main air duct unit 2 includes a motor mounting plate 21, a motor bracket 22, a motor 23, a shaft sleeve 24, centrifugal blades 25, and a volute 26. The motor 23 is mounted on the motor bracket 22 and the motor mounting plate 21 via the shaft sleeve 24, and the motor 23 is embedded in the centrifugal blades 25. The motor mounting plate 21, the motor bracket 22, the motor 23, the shaft sleeve 24, and the centrifugal blades 25 are coaxially connected, and the motor mounting plate 21, the motor bracket 22, the motor 23, the shaft sleeve 24, and the centrifugal blades 25 are disposed within the volute 26. When the main air duct unit 2 is in operation, the motor 23 drives the centrifugal blades 25 to rotate, causing the drawn indoor air to flow within the volute and be delivered to the air outlet 261 of the main air duct unit 2, i.e., the upper portion of the floor-standing air conditioner.

[0040] like Figure 4-Figure 6 As shown, the air supply assembly 4 includes an air outlet frame 41, a first motor 42, a fan 43, a drive assembly 47, and a curved air guide plate 46. The first motor 42 is coaxially connected to the fan 43 and is disposed within the air outlet frame 41. The first motor 42 drives the fan 43 to rotate. The drive assembly 47 includes a second motor 44 and a gear 45. The second motor 44 is connected to the gear 45 and disposed within the air outlet frame 41, and the second motor 44 drives the gear 45 to rotate. The curved air guide plate 46 is disposed within the air outlet frame 41 and meshes with the gear 45. It rotates within a preset range as the gear 45 rotates, thereby controlling the exhaust direction.

[0041] Specifically, the air outlet frame 41 includes a first side wall 411, a second side wall 412, a third side wall 413, a fourth side wall 414, and a front baffle 415. The first side wall 411, the second side wall 412, the third side wall 413, and the fourth side wall 414 are sequentially connected to form a closed side surface. Furthermore, the first side wall 411, the second side wall 412, the third side wall 413, and the fourth side wall 414 enclose an air inlet 416. The three edges of the front baffle 415 are fixedly connected to the first side wall 411, the third side wall 413, and the fourth side wall 414, respectively. Furthermore, the front baffle 415, the first side wall 411, the second side wall 412, and the third side wall 413 enclose an air outlet 417. Figure 4 The air inlet 416 can be seen through the air outlet 417, that is, the air outlet frame 41 is a front-to-back through-structure. The air outlet 417 is arranged corresponding to the air outlet of the housing 1, so that the air supply assembly 4 is arranged on the air supply path of the vertical air conditioner in the housing 1, the air inlet of the air outlet frame is connected to the air supply path, and the air outlet of the air outlet frame is connected to the air outlet. In addition, a slide is provided on the first side wall 411, including a first slide 418 and a second slide 419. The first slide 418 is used for the first baffle 461 of the curved air guide plate 46 to slide within the first slide, and the second slide 419 is used for the second baffle 462 of the curved air guide plate 46 to slide within the second slide. The specific connection relationship between the air outlet frame 41 and the curved air guide plate 46 will be described in detail below.

[0042] In addition, in an embodiment of the present invention, the fan 43 is coaxially fixedly connected to the first motor 42 by screws, and the first motor 42 is pressed by the motor cover and fixedly connected to the first side wall 411 of the air outlet frame 41. The end of the fan 43 that is not connected to the first motor 42 is fixedly connected to the third side wall 413. The fan 43 has the function of increasing the air volume and increasing the wind speed. In an embodiment of the present invention, the fan 43 can be a cross-flow fan blade or an axial flow fan blade, both of which can achieve the effect of the embodiment of the present invention. In addition, those skilled in the art should understand that any type of fan that can achieve the function of the fan of the present invention falls within the scope of the rights claimed for protection by the present invention.

[0043] In addition, if Figure 7 As shown, the curved air guide plate 46 is located between the two side walls, and at least partially constitutes the volute tongue portion of the fan. Specifically, it includes a first baffle 461, a second baffle 462 and a sliding side plate 463. Among them, the one side edges of the first baffle 461 and the second baffle 462 extending in the length direction are fixedly connected, and a preset angle is formed. The preset angle is less than or equal to 90 degrees. On the first baffle 461, a first sliding portion 465 is provided on the side facing the slide groove, and on the second baffle 462, a second sliding portion 466 is provided on the side facing the slide groove. The sliding side plate 463 is respectively connected to the short sides of the first baffle 461 and the second baffle 462 on the same side, and the side edge that is not connected to the first baffle 461 and the second baffle 462 is arc-shaped. In an embodiment of the present invention, as Figure 8 As shown, a tooth portion 464 is provided on the arc-shaped edge.

[0044] like Figure 9-10 As shown, the first sliding portion of the first baffle 461 is embedded in the first slide groove 418, and the second sliding portion of the second baffle 462 is embedded in the second slide groove 419. The first slide groove 418 and the second slide groove 419, both of which are arcs, are concentric with the fan 43, and can ensure that the distance between the curved air guide plate 46 and the fan 43 remains unchanged during the movement, and only the exhaust angle changes. When the gear 45 rotates under the drive of the second motor 44, the tooth portion 464 rotates with the rotation of the gear 45, thereby driving the curved air guide plate 46 to rotate within a preset range. That is, the first baffle 461 slides in the first slide groove 418, and the second baffle 462 slides in the second slide groove 419, and the first baffle 461 and the second baffle 462 slide synchronously in the same direction. When the first baffle 461 and the second baffle 462 slide upward synchronously, as shown Figure 9 As shown, the air F that has completed the heat exchange is discharged upward. When the first baffle 461 and the second baffle 462 slide downward synchronously, as shown in FIG. Figure 10 As shown, the air F that completes the heat exchange is discharged downward.

[0045] In this embodiment of the present invention, the third side wall 413 may also be provided with a sliding groove similar to that on the first side wall 411. Correspondingly, a sliding portion similar to the first sliding portion and the second sliding portion may also be provided on the side of the curved air guide plate 46 facing the third side wall 413, so that the sliding portion is embedded in the sliding groove on the third side wall 413 and slides.

[0046] In the embodiment of the present invention, the first motor 42 and the second motor 44 may be motors such as a stepper motor and a brushless DC motor.

[0047] The working principle of the vertical air conditioner with increased exhaust volume provided by the embodiment of the present invention will be described in detail below.

[0048] like Figure 11 As shown, after the vertical air conditioner with increased exhaust volume provided by an embodiment of the present invention receives a cooling or heating instruction, the controller starts the motor of the main air duct unit 2. The motor drives the centrifugal fan blades to rotate, allowing indoor air to enter the main air duct unit 2 from the air inlet at the lower portion of the housing 1, then pass through the volute 26 and be discharged from the air outlet 261. The air discharged from the air outlet 261 will enter the heat exchange unit 3, and after cooling or heating through heat exchange, it will enter the air supply assembly 4. After the cooled or heated air F is concentrated inside the air supply assembly 4, the curved air guide plate rotates upward as the gear rotates, so that the cooled or heated air F is finally discharged upward through the air outlet 417. Figure 12 This is a schematic diagram of the air path when the air after cooling or heating is finally discharged downward through the air outlet 417. The air path and principle are the same as those when the air is discharged upward, so they will not be repeated here.

[0049] During the above working process, since the air after cooling or heating is concentrated in the air supply assembly 4, the air volume becomes larger and the wind speed increases accordingly. In addition, the exhaust direction is limited by the curved air guide plate, so the air supply distance increases accordingly.

[0050] In summary, the air supply assembly and the vertical air conditioner equipped with the air supply assembly provided by the present invention have the following beneficial effects compared with the prior art. 1. The present invention adds an air supply assembly to the original vertical air conditioner, so that the air after cooling or heating is concentrated again through the air supply assembly and then discharged, thereby reducing the air volume loss from the lower part to the upper part, increasing the exhaust volume and exhaust speed, and also increasing the air supply distance, thereby improving the user experience. 2. Without reducing the exhaust volume, the present invention can use components with smaller volume and power than the prior art, thereby reducing the volume of the vertical air conditioner, reducing costs, and improving market competitiveness.

[0051] The above describes in detail an air supply assembly and a vertical air conditioner incorporating the air supply assembly provided by the present invention. For those skilled in the art, any obvious modification made thereto without departing from the essence of the present invention would constitute an infringement of the patent rights of the present invention and would incur corresponding legal liability.
