[0037] This invention proposes a floor-standing air conditioner indoor unit, which will be described below in conjunction with... Figures 1 to 6 The floor-standing air conditioner indoor unit of this invention will be described in detail.

[0038] In one embodiment of the present invention, such as Figures 1 to 3 As shown, the floor-standing air conditioner indoor unit includes:

[0039] The housing 100 has an air inlet 121 and an air outlet 111.

[0040] A fan assembly 10 is disposed inside the housing 100, and an air outlet duct is formed between the fan assembly 10 and the air outlet 111.

[0041] The first cross-flow fan 20 is located in the air outlet direction of the air outlet duct;

[0042] The first guide plate 31 is disposed on the outside of the first cross-flow impeller 20;

[0043] The first drive assembly 50 is connected to the first guide plate 31 to drive the first guide plate 31 to rotate around the first cross-flow impeller 20, so as to adjust the air outlet direction of the first cross-flow impeller 20.

[0044] Specifically, the housing 100 includes a front housing 110 and a rear housing 120. The front housing 110 has an air outlet 111 extending vertically therefrom, and the rear housing 120 has an air inlet 121 extending vertically therefrom. Inside the housing 100, a heat exchanger 70, a fan assembly 10, and a first cross-flow impeller 20 are arranged sequentially along the air outlet direction. That is, the heat exchanger 70 is located on the air inlet side of the fan assembly 10, and the first cross-flow impeller 20 is located on the air outlet side of the fan assembly 10. Through the operation of the fan assembly 10, air is introduced into the housing 100 from the air inlet 121, and undergoes heat exchange through the heat exchanger 70. The heat-exchanged air then enters the air outlet duct between the fan assembly 10 and the air outlet 111, and finally is sent out from the air outlet 111 through the first cross-flow impeller 20.

[0045] The fan assembly 10 includes any one of a centrifugal impeller, an axial impeller, and a cross-flow impeller. For example, the fan assembly 10 may include multiple centrifugal impellers arranged side by side in a vertical direction, thus enabling the introduction of a large amount of air from the outside into the housing 100 and then forward delivery to the first cross-flow impeller 20. In this embodiment, the fan assembly 10 includes only a second cross-flow impeller extending vertically. The main function of the second cross-flow impeller is to introduce air from the outside into the air duct and then out through the first cross-flow impeller 20. Therefore, the impeller diameter and power of the second cross-flow impeller are correspondingly greater than those of the first cross-flow impeller 20. This invention does not limit the fan type or specific structure of the fan assembly 10, as long as the fan assembly 10 can introduce air from the outside into the housing 100.

[0046] In this invention, the first cross-flow fan 20 is disposed in the air outlet direction of the air outlet duct, specifically including the following three implementation methods: the first cross-flow fan 20 is disposed inside the air outlet duct; the first cross-flow fan 20 is disposed at the air outlet 111; the first cross-flow fan 20 is disposed outside the air outlet duct, but located in the air outlet direction of the air outlet duct.

[0047] Existing floor-standing air conditioner indoor units use fixed grilles or air guides for airflow, which results in poor airflow guidance and poor visibility of left and right airflow. Although the airflow angle and direction can be adjusted by changing the deflection angle of the grille, the larger the deflection angle, the smaller the air volume and the shorter the air delivery distance.

[0048] The present invention provides a floor-standing air conditioner indoor unit, in which a fan assembly 10 and a first cross-flow fan wheel 20 are arranged sequentially inside the housing 100 along the air outlet direction of the indoor unit. The operation of the fan assembly 10 introduces air into the indoor unit, and then the first cross-flow fan wheel 20 expels the air out of the indoor unit. During the air guiding process, the first guide plate 31 is driven by the first drive assembly 50 to rotate around the first cross-flow fan wheel 20 to adjust the air outlet direction of the first cross-flow fan wheel 20, thereby realizing that the air is blown out from different angles, the air guiding angle is larger, the left and right sweeping visibility effect is better, and the air volume and air delivery distance are larger during the sweeping process.

[0049] In one embodiment, the first cross-flow fan 20 is disposed at the air outlet 111. Specifically, the first cross-flow fan 20 is partially located within the air outlet duct in its radial direction, while a portion extends beyond the air outlet 111. It can be understood that the partial extension of the first cross-flow fan 20 beyond the air outlet 111 enhances the visual effect of the left and right airflow. Of course, if the first cross-flow fan 20 extends excessively beyond the air outlet 111 or is completely located outside the air outlet 111, it will affect the overall aesthetics of the unit.

[0050] In this embodiment, as Figure 2 and Figure 3 As shown, the first cross-flow fan 20 is disposed within the air outlet duct, and the distance between the first cross-flow fan 20 and the air outlet 111 is less than the distance between the first cross-flow fan 20 and the fan assembly 10. It can be understood that, compared to the previous embodiment, this embodiment, by disposing of the first cross-flow fan 20 within the air outlet duct, can better guide the airflow from the duct. Furthermore, placing the first cross-flow fan 20 close to the air outlet 111 improves the visualization of the left and right airflow.

[0051] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, the floor-standing air conditioner indoor unit also includes a volute 41 and a volute tongue 42. The volute 41 is located on the outside of the fan assembly 10 and extends towards the air outlet 111. The volute tongue 42 is located on the outside of the first cross-flow impeller 20 and extends towards the air outlet 111. The volute 41 and the volute tongue 42 together form the air outlet duct. It can be understood that through the cooperation of the volute 41 and the volute tongue 42, the airflow from the fan assembly 10 can be guided to the first cross-flow impeller 20. Specifically, due to the relatively long extension length of the volute 41, reinforcing ribs are provided on the side of the volute 41 facing away from the air outlet duct to enhance its mechanical strength. It is worth noting that the portion of the volute near the air outlet is arc-shaped to form an arc section. This arc section and the volute tongue together form a semi-circular space, which provides rotation space for the first guide plate.

[0052] Furthermore, the first guide vane 31 has a first position located between the volute tongue 42 and the first cross-flow impeller 20, and a second position with the air outlet 111 closed. The first drive assembly 50 is used to drive the first guide vane 31 to move between the first position and the second position. Specifically, as shown... Figure 3 As shown, when the first drive assembly 50 drives the first guide plate 31 to rotate between the volute tongue 42 and the first cross-flow impeller 20, the first guide plate 31 is in the first position, and at this time, the air outlet 111 is in the open state; when the first drive assembly 50 drives the first guide plate 31 to rotate to the air outlet 111, the first guide plate 31 closes and seals the air outlet 111, and the second guide plate 32 is in the second position, at which time the air outlet 111 is in the closed state; and when the first guide plate 31 moves back and forth between the first position and the second position, the guiding direction of the first guide plate 31 will also change accordingly, such as... Figure 2 As shown, when the first guide plate 31 rotates toward the volute tongue 42, the first cross-flow impeller 20 sweeps air to the right, while when the first guide plate 31 rotates toward the air outlet 111, the first cross-flow impeller 20 sweeps air to the left.

[0053] In one embodiment, such as Figure 3 and Figure 4 As shown, a second guide plate 32 connected to the first guide plate 31 is also provided on the outer periphery of the first cross-flow impeller 20. The first guide plate 31 and the second guide plate 32 form the air supply duct of the first cross-flow impeller 20 and the air outlet of the first cross-flow impeller 20. It can be understood that the first guide plate 31 and the second guide plate 32 are respectively equivalent to the volute and volute tongue of the first cross-flow impeller 20, which can introduce the air from the outlet duct into the air supply duct and send it out from the air outlet.

[0054] Furthermore, such as Figure 4As shown, an air outlet grille 33 is also provided on the outer periphery of the first cross-flow impeller 20. The air outlet grille 33 is located between the first guide plate 31 and the second guide plate 32, and the first guide plate 31, the air outlet grille 33, and the second guide plate 32 are connected in sequence. It can be understood that the air outlet grille 33 covers the air inlet, which can play a certain role in guiding the air and also prevent large foreign objects from entering and affecting the operation of the first cross-flow impeller 20.

[0055] Furthermore, such as Figure 4 As shown, a windmill protective net 34 is also provided on the outer periphery of the first cross-flow impeller 20. The first cross-flow impeller 20 is located between the windmill protective net 34 and the air outlet grille 33. The first guide plate 31, the air outlet grille 33, the second guide plate 32, and the windmill protective net 34 are connected in sequence. It can be understood that the first guide plate 31, the air outlet grille 33, the second guide plate 32, and the windmill protective net 34 together form an outer shell surrounding the first cross-flow impeller 20. When the first drive assembly 50 drives the first guide plate 31 to rotate, it is equivalent to driving the entire outer shell to rotate. It is worth noting that the diameter of the outer shell of the first cross-flow impeller 20 is smaller than the diameter of the semi-circular space formed by the arc-shaped part and the volute tongue. In this way, the outer shell can rotate freely and unobstructed within the semi-circular space, while also enhancing the visualization effect of left and right air sweeping.

[0056] In this embodiment, as Figure 5 As shown, the first driving assembly 50 includes two driving members, which are respectively disposed at both ends of the first guide plate 31 and both driving members are connected to the first guide plate 31. It can be understood that using two driving members respectively disposed at both ends of the first guide plate 31 to jointly drive the first guide plate 31 to rotate is beneficial for maintaining the stability of the rotation of the first guide plate 31. Of course, in other embodiments, a driving member may only be disposed at one end of the first guide plate 31.

[0057] In this embodiment, as Figure 6 As shown, the driving component includes a first motor 51, a gear 52, and a ring rack 53. The motor shaft of the first motor 51 is connected to the gear 52, the gear 52 meshes with the ring rack 53, and the ring rack 53 is fixedly connected to the first guide plate 31. Specifically, the driving component also includes an upper cover 54 and a lower cover 55, which together form a mounting cavity. The ring rack 53 and the gear 52 are installed in the mounting cavity, and the first motor 51 is installed on the upper cover 54. The motor shaft of the first motor 51 passes through the upper cover 54 and is connected to the gear 52. It can be understood that the first motor 51 drives the gear 52 to rotate, which in turn drives the ring rack 53 to rotate, thereby driving the first guide plate 31 to rotate.

[0058] Furthermore, such as Figure 1 and Figure 5As shown, the floor-standing air conditioner indoor unit also includes a second drive assembly 60, which is disposed at one end of the first cross-flow fan 20. The second drive assembly 60 includes a motor cover 61 and a second motor 62. The motor cover 61 is fixedly connected to the first guide plate 31, and the second motor 62 is installed inside the motor cover 61, which is used to fix the motor. The motor shaft of the second motor 62 is connected to the first cross-flow fan 20, and the second motor 62 is used to drive the first cross-flow fan 20 to rotate.

[0059] This invention also proposes an air conditioner, which includes an outdoor unit and a floor-standing indoor unit. The specific structure of the floor-standing indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0060] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
