Fig. 1 is a schematic structural view of a vertical air conditioner indoor unit according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 to 4, an embodiment of the present utility model provides a vertical air conditioner indoor unit 100 including a uniform air outlet duct 140 having an outlet facing forward and an air guide pillar 180. The rear end of the air-homogenizing air outlet duct 140 is connected with a first air outlet duct, an air-inducing duct 130 and a second air outlet duct which are sequentially arranged along the transverse direction, so that air flows from the first air outlet duct, the air-inducing duct 130 and the second air outlet duct are blown out through the air-homogenizing air outlet duct 140. The rear surface of the air guiding column 180 is arched backward, so that the air guiding column 180 has a first air guiding surface arched backward, and the air guiding column 180 is disposed in the uniform air outlet duct 140.

In the vertical air conditioner indoor unit 100 of the embodiment of the utility model, when the first air outlet duct and the second air outlet duct are used for discharging air, indoor air flows are driven to be blown out from the air guiding duct under the action of negative pressure, three air flows are mixed in the air homogenizing air outlet duct 140 and then are blown out, the first air guiding surface of the air guiding column 180 has a guiding effect on the air flows, so that the air flows and the air flows are convenient to flow and mix, and the air homogenizing effect is better. In addition, the first air outlet duct and the second air outlet duct actively introduce air flow, and the air inlet duct 130 passively introduces air flow, so that the air inlet amount is large.

In some embodiments of the present utility model, the air guiding columns 180 may be disposed movably back and forth, so that the air flow may be guided at different positions in the uniform air outlet duct 140 to meet different usage requirements.

As shown in fig. 2, when the air guide post 180 moves to the rear end of the uniform air outlet duct 140, the effective air outlet area of the outlet of the uniform air outlet duct 140 is larger, so that the air outlet quantity is larger, the heat exchange speed of the room is high, and the air guide post is suitable for a rapid heat exchange scene. As shown in fig. 3, when the air guide post 180 moves to the middle of the uniform air outlet duct 140, the effective air outlet area of the outlet of the uniform air outlet duct 140 becomes smaller, so that the air output becomes smaller, but the uniform air output becomes larger, the air outlet temperature is higher, the cooling effect is better, and the constant temperature control device is suitable for a constant temperature control scene.

As shown in fig. 4, the air guide pillar 180 closes the outlet of the uniform air outlet duct 140 when it is at the frontmost movement position. For example, when the vertical air conditioner indoor unit 100 is turned off, the air guide pillar 180 automatically moves to the outlet position of the uniform air outlet duct 140 to close the outlet of the uniform air outlet duct 140, so that the vertical air conditioner indoor unit 100 can be prevented from entering impurities such as dust when not in use.

In some embodiments of the present utility model, the indoor unit 100 of the vertical air conditioner has at least three air outlet modes, i.e. a large air volume aggregation air distribution mode, a small air volume aggregation air distribution mode and a closed mode. The indoor unit 100 of the floor air conditioner determines an air outlet mode of the indoor unit 100 of the floor air conditioner by comparing an absolute value of a temperature difference between the measured indoor temperature and the set temperature with a set temperature difference threshold value through a temperature sensor. The temperature difference threshold is set at 1 to 3 ℃, preferably at 2 ℃. When the absolute value of the temperature difference between the indoor temperature and the set temperature is greater than or equal to the set temperature difference threshold value, a large air quantity aggregation uniform air mode is started to realize rapid indoor cooling or heating, and at the moment, the air guide column 180 is at the final movement position as shown in fig. 2. When the absolute value of the temperature difference between the indoor temperature and the set temperature is smaller than the set temperature difference threshold value, a small air quantity aggregation uniform air mode is started, so that more comfortable air supply experience is provided while the indoor temperature is maintained, and at the moment, the air guide column 180 is at the movement position of the middle part of the uniform air outlet duct 140, as shown in fig. 3.

The wind homogenizing outlet duct 140 has a first wind homogenizing surface 141 and a second wind homogenizing surface 142. The first air-distributing surface 141 is connected with the first air-out surface, and the second air-distributing surface 142 is connected with the fourth air-out surface, so that the air-out of the first air-out air duct and the second air-out air duct is smoother, and the noise is lower.

In some embodiments of the present utility model, as shown in fig. 2 to 4, the stand-up air conditioner indoor unit 100 further includes a first air outlet column 110 and a second air outlet column 120. The first air outlet column 110 has a first air outlet duct and a first air homogenizing surface 141.

In the transverse direction, the length of the first air outlet post 110 is greater than the length of the second air outlet post 120. That is, the dimensions of the first air outlet column 110 are larger than those of the second air outlet column 120 along the front-rear direction and along the transverse direction, so that the vertical air conditioner indoor unit 100 is of an asymmetric design, and the appearance is more novel and unique, and the competitiveness of the product is improved.

In some embodiments of the present utility model, as shown in fig. 2 to 4, the first air distribution surface 141 arches away from the second air outlet post 120, and the second air distribution surface 142 arches away from the first air outlet post 110, so that at least a portion of the section of the air distribution outlet duct 140 from the front end tapers from back to front.

The gradually-expanding section is beneficial to the air flow in the first air outlet air duct, the second air outlet air duct and the induced air duct 130 to enter the uniform air outlet air duct 140, and the gradually-expanding section enables the air flow to have a pressurizing effect and accelerates the flow of the air flow. The divergent section and the convergent section are matched to be used, so that the air flow can be fully mixed in the uniform air outlet duct 140 and the blowing out is accelerated.

In some embodiments of the present utility model, the angle between the tangent plane at the front edge of the first air distribution surface 141 and the vertical plane extending in the lateral direction is greater than the angle between the tangent plane at the front edge of the second air distribution surface 142 and the vertical plane extending in the lateral direction.

Preferably 2.5 times.

In some embodiments of the present utility model, as shown in fig. 2 to 4, a first air inlet communicating with the first air outlet duct is provided on the first air outlet column 110. The first air outlet column 110 is internally provided with a heat exchanger 113 and a heat exchange fan 114, and the heat exchange fan 114 enables air flow to enter the first air outlet column 110 from the first air inlet, and forms heat exchange air flow after heat exchange with the heat exchanger 113, and flows out from the first air outlet duct. The heat exchange fan 114 is a cross flow fan. One end of the first air outlet surface far away from the first air homogenizing surface 141 is connected with a volute tongue of the heat exchange fan 114, and the connection part is in natural transition, so that air supply is smoother, and noise is lower.

The second air outlet column 120 is provided with a second air inlet communicated with the second air outlet channel, the second air outlet column 120 is internally provided with a non-heat exchange fan 123, and the non-heat exchange fan 123 enables air flow to enter the second air outlet column 120 from the second air inlet and then flow out from the second air outlet channel.

One end of the fourth air outlet surface far away from the second air homogenizing surface 142 is connected with the volute tongue of the non-heat exchange fan 123, and the connection part is in natural transition, so that air supply is smoother, and noise is lower.

When the vertical air conditioner indoor unit 100 works, when the first air outlet air channel and the second air outlet air channel are used for air outlet, the indoor air flow is driven to blow out from the air guiding air channel 130 under the action of negative pressure, and then the heat exchange air flow, the non-heat exchange air flow and the indoor air flow are mixed in the air homogenizing air outlet air channel 140 to form cool and non-cool mixed air and then blow out, so that cold air is prevented from directly blowing out, and a user is more comfortable.

In some embodiments of the present utility model, as shown in fig. 1, the stand air conditioner indoor unit 100 further includes a lower case 160 and a functional module 170. The lower case 160 is disposed under the first and second

When the functional module 170 is a fresh air device, the outlet of the functional module 170 may be the outlet of a lower fan, which may also be referred to as a fresh air fan.

In some embodiments of the present utility model, the outlet of the functional module 170 communicates with the second outlet air duct on the inlet side of the non-heat exchanging fan 123. The air flow flowing in from the second air inlet and the air flow flowing out from the outlet of the functional module 170 are mixed first and then enter the second air outlet air duct through the non-heat exchange fan 123, so that the air flow is mixed more uniformly, and the mixing effect is better. In some embodiments, a damper may be disposed at the second air inlet, so that the second air inlet may be closed, and the second air outlet duct only flows out of the airflow from the airflow inlet. When the lower fan does not work, the second air outlet air duct only flows out of the air flow from the second air inlet.
