The invention provides a floor-standing type air-conditioning indoor unit.

In an embodiment of the present invention, as shown in FIGS. 1 to 4 , the floor-standing air conditioner indoor unit 100 includes a housing, a top air outlet frame 3, a fan assembly 4 and a heat exchanger (not shown), wherein the housing includes an outer shell 1 and an air duct housing 2 disposed in the outer shell 1, an air duct 20 is formed in the air duct housing 2, and the air duct housing 2 is provided with a rear air inlet 211 and a front air outlet 221 connected to the air duct 20; the lower end of the top air outlet frame 3 is connected to the air duct 20, and the top air outlet frame 3 A top air outlet 31 is formed on the front side, and the top air outlet frame 3 can be installed on the top of the air duct shell 2 movably up and down so that the top air outlet 31 extends out of the outer shell 1 or retracts into the air duct shell 2; the fan assembly 4 is installed in the air duct 20 to suck the air flow into the air duct shell 2 from the rear air inlet 211 and blow it out from the front air outlet 221 or from the front air outlet 221 and the top air outlet 31; the heat exchanger is installed in the outer shell 1 and is located at the rear of the air duct shell 2.

The front air outlet 221 referred to in this embodiment refers to the side facing the user after the floor-standing air conditioner indoor unit 100 is installed in place, and the rear air inlet 211 is on the side facing away from the user. The lower end and the front side of the top air outlet frame 3 are both open, the front side opening forms the top air outlet 31, and the lower end opening is connected to the air duct 20 in the air duct shell 2. The top air outlet 31 can be set on the same side as the front air outlet 221, which is also the side facing the user. The top air outlet frame 3 can be installed on the top of the air duct shell 2 so that the top air outlet 31 of the top air outlet frame 3 can extend out of the housing 1 during the upward movement, or retract into the air duct shell 2 during the downward movement.

When the floor-standing air conditioner indoor unit 100 of this embodiment is working, the airflow enters the housing 1 and exchanges heat with the heat exchanger. The airflow after heat exchange is sucked into the air duct housing 2 from the rear air inlet 211 and blown out to the room from the front air outlet 221 along the air duct 20. In addition, the floor-standing air conditioner indoor unit 100 of this embodiment also has a top outlet mode. When the top air outlet 31 is needed to supply air, the top outlet mode is entered, and the top outlet frame 3 moves upward so that the top air outlet 31 extends out of the housing 1, that is, the top air outlet 31 leaks out of the housing 1, and a part of the airflow in the air duct 20 is blown out to the room from the front air outlet 221, and the other part of the airflow can be blown into the top air outlet frame 3 from the lower end of the top air outlet frame 3, and blown out to the room through the top air outlet 31, so that the front air outlet 221 and the top air outlet 31 can supply air at the same time, expanding the air supply range. In addition, the top air outlet frame 3 can be moved up and down to adjust the air supply height and air supply range of the top air outlet frame 3 to meet the different usage requirements of users. When the top air outlet 31 is not needed to supply air, the top air outlet mode is exited, and the top air outlet frame 3 moves downward, so that the top air outlet 31 is retracted into the air duct shell 2, that is, the top air outlet 31 is hidden in the air duct shell 2. At this time, the airflow in the air duct 20 is all blown out to the room from the front air outlet 221, and the top air outlet 31 no longer supplies air to the room, thereby further meeting the different usage requirements of users and improving the user experience.

The floor-standing air-conditioning indoor unit 100 of the present embodiment can realize simultaneous air supply from the front air outlet 221 and the top air outlet 31, thereby expanding the air supply range. The air supply height and air supply range of the top air outlet frame 3 can also be adjusted. It is flexible and convenient to use, and can realize separate air supply from the front air outlet 221, thereby meeting the different usage requirements of users and improving the user experience.

The air duct shell 2 of the present embodiment includes an air duct rear shell 21 and an air duct front shell 22, the air duct rear shell 21 is connected to the air duct front shell 22, and an air duct 20 is formed between the air duct front shell 22 and the air duct rear shell 21; the fan assembly 4 includes a centrifugal fan 41, the rear air inlet 211 includes a first air inlet 211a arranged on the air duct rear shell 21, the air duct 20 includes a first air duct 201 formed between the first air inlet 211a and the front air outlet 221, the lower end of the top air outlet frame 3 is connected to the first air duct 201, and a centrifugal fan 41 is arranged in the first air duct 201. The fan assembly 4 also includes an axial flow fan 42, the rear air inlet 211 also includes a second air inlet 211b arranged on the rear shell of the air duct 21, the second air inlet 211b is located above the first air inlet 211a, the front air outlet 221 is arranged corresponding to the second air inlet 211b, the air duct 20 also includes a second air duct 202 formed between the second air inlet 211b and the front air outlet 221, and the axial flow fan 42 is arranged in the second air duct 202.

Specifically, the air duct rear shell 21 of this embodiment is provided with a first air inlet 211a near the bottom, a second air inlet 211b near the top, and the air duct front shell 22 is provided with a front air outlet 221 near the top, and the front air outlet 221 is arranged opposite to the second air inlet 211b. The centrifugal fan 41 is located below the axial flow fan 42, and the air supply principle of the axial flow fan 42 is axial air inlet and radial air outlet. Therefore, when the centrifugal fan 41 is working, the centrifugal fan 41 can guide the air flow from the first air inlet 211a into the first air duct 201, and the air flow runs upward along the first air duct 201 and blows out to the front side through the front air outlet 221. The air supply of the axial flow fan 42 is axial air inlet and axial air outlet. Therefore, when the axial flow fan 42 is working, the axial flow fan 42 can guide the air flow from the second air inlet 211b into the second air duct 202 and blow out to the front side through the front air outlet 221. The dashed arrows in FIGS. 5 to 7 indicate the flow direction of the air flow.

It should be noted that, in one embodiment, when the temperature difference between the indoor ambient temperature and the ideal temperature required by the user is small, the centrifugal fan 41 or the axial flow fan 42 can be selected to work alone, that is, only the centrifugal fan 41 participates in the air supply, or only the axial flow fan 42 participates in the air supply. In another embodiment, when the temperature difference between the indoor ambient temperature and the ideal temperature required by the user is large, the centrifugal fan 41 and the axial flow fan 42 can be selected to work at the same time, that is, the centrifugal fan 41 and the axial flow fan 42 can participate in the air supply at the same time, which increases the air intake area, the air supply distance is longer and the air supply range is expanded, and the heat exchange efficiency is improved, and the comfort is enhanced. In addition, the present embodiment increases the air intake area through the double air duct 20 air supply mode of the first air duct 201 and the second air duct 202, compared with the single air duct air supply mode, so that the air intake air flow is uniform, the heat exchange of the heat exchanger is uniform, the heat exchange efficiency is improved, and the system energy efficiency is improved. Moreover, under the same air volume, compared with the single air duct 20 air supply mode, the noise of the double air duct 20 air supply mode is also reduced, reducing noise pollution. According to the actual needs of the user, the centrifugal fan 41 or the axial flow fan 42 can be selected to work alone, or the centrifugal fan 41 or the axial flow fan 42 can be selected to work simultaneously.

In this embodiment, a guide tube 23 is installed at the second air inlet 211b, the guide tube 23 extends toward the front air outlet 221, and the axial flow fan 42 is installed in the guide tube 23. The area of the front air outlet 221 is larger than the area of the front port of the guide tube 23. As shown in Figures 4 to 6, the guide tube 23 of this embodiment is trumpet-shaped, and the rear port of the guide tube 23 is connected to the edge of the second air inlet 211b, and the front port of the guide tube 23 extends to one side of the front air outlet 221, and the inner diameter of the guide tube 23 is reduced from the back to the front, and the axis of the axial flow fan 42 and the axis of the guide tube 23 are located on the same straight line. The wind inhaled into the second air duct 202 from the second air inlet 211b can be gradually concentrated along the guide tube 23 toward the axial direction of the axial flow fan 42, which is convenient for the axial flow fan 42 to supply air, and the area of the front air outlet 221 is larger than the area of the front port of the guide tube 23, which is conducive to expanding the air supply range.

Furthermore, the guide tube 23 is integrally formed in the air duct rear shell 21, which is not only easy to manufacture, but also omits the assembly gap and error, and has good structural stability. There is a gap between the outer wall of the guide tube 23 and the inner side wall of the air duct rear shell 21, and the lower end of the top air outlet frame 3 is connected to the first air duct 201 through the gap. When entering the top air outlet mode, the centrifugal fan 41 works, and the air flow in the first air duct 201 is blown upward into the top air outlet frame 3 through the gap, so as to realize the top air outlet 31 to supply air. When exiting the top air outlet mode, the centrifugal fan 41 works, and when the air flow passes through the gap, a negative pressure can be formed in the first air duct 201. Under the action of the negative pressure, an air flow can be formed in the first air duct 201 to circulate toward the front air outlet 221, thereby increasing the air output of the floor-standing air conditioner indoor unit 100, increasing the air supply distance, and improving the heat exchange efficiency of the floor-standing air conditioner indoor unit 100.

As shown in Fig. 5 and Fig. 6, vertical cut edges 231 are provided on both sides of the outer wall of the guide tube 23, and the vertical cut edges 231 are provided in parallel with the inner side wall of the air duct rear shell 21. The provision of the vertical cut edges 231 increases the gap width, so that the airflow in the first air duct 201 can pass through the gap more and smoothly into the top air outlet frame 3, increase the airflow of the top air outlet 31, and improve the effectiveness of the top air outlet mode.

In this embodiment, the second air duct 202 is provided with a stator blade 5, which is arranged opposite to the axial flow fan 42, and the axial flow fan 42 is located between the second air inlet 211b and the stator blade 5. The stator blade 5 can reorganize the airflow, so that the air output of the axial flow fan 42 is more uniform and the noise is lower.

In this embodiment, the front air outlet frame 24 is provided at the position corresponding to the axial flow fan 42 of the air duct front shell 22, and the front air outlet frame 24 forms a front air outlet 221. A display light strip 6 is installed on the front side of the front air outlet frame 24, and the display light strip 6 is provided corresponding to the front air outlet 221. The display light strip 6 of this embodiment has a prompting function. For example, when cold air is blown out from the front air outlet 221, the display light strip 6 is blue, indicating that the floor-standing air conditioner indoor unit 100 is currently in the cooling mode; when hot air is blown out from the front air outlet 221, the display light strip 6 turns red, indicating that the floor-standing air conditioner indoor unit 100 is currently in the heating mode. It can be understood that the display light strip 6 can be controlled by the temperature sensor to display the color. The display light strip 6 of this embodiment can not only play a prompting role, but also improve the appearance of the floor-standing air conditioner indoor unit 100.

Furthermore, the front air outlet frame 24 is equipped with a transverse air guide assembly and a vertical air guide assembly, wherein the transverse air plate assembly includes a plurality of transverse air guide plates 7 arranged at intervals in the vertical direction, and a transverse driving member for driving the transverse air guide plates 7 to swing; the front air outlet frame 24 is also equipped with a vertical air guide assembly, and the vertical air plate assembly includes a plurality of vertical air guide plates 8 arranged at intervals in the horizontal direction, and a vertical driving member for driving the vertical air guide plates 8 to swing.

The floor-standing air conditioner indoor unit 100 further includes a driving device installed on the air duct housing 2, the driving device is connected to the top air outlet frame 3, and the driving device is used to drive the top air outlet frame 3 to move up and down. The driving device of this embodiment can be a device such as a screw mechanism or a gear rack mechanism that can drive the top air outlet frame 3 to move up and down. For example, the driving device is a gear rack mechanism, the upper end of the rack is connected to the top air outlet frame 3, and the lower end of the rack is meshed with the gear. By driving the gear to rotate through the motor, the top air outlet frame 3 can be driven to move up and down through the rack, so that the top air outlet 31 can discharge air or stop discharging air.
