Figure 3 is an enlarged N-N cross-sectional view of Figure 1 . Figure 4 is a diagram shown in Figure 2 Schematic diagram of a vertical air conditioner indoor unit when both the first air guide part and the second air guide part guide air forward. Figure 4 uses solid arrows to indicate the flow direction of the heat exchange air flow, and hollow arrows to indicate the flow direction of the indoor air.

As shown in FIGS. 1 to 4 , the vertical air conditioner indoor unit according to the embodiment of the present invention may generally include a first column housing 10 , a second column housing 20 and a second fan 24 .

The first column shell 10 is in the shape of a vertical column, that is, a hollow columnar shell. A first air outlet 12 for blowing out heat exchange airflow is provided on the front side of the first column shell 10 . The first air outlet 12 opens forward. The "heat exchange air flow" refers to the air flow that completes heat exchange with the heat exchanger 17 of the air conditioner and is used to adjust the indoor temperature. The heat exchanger 17 is connected with the heat exchanger of the compressor, the outdoor unit, the throttling device and other refrigeration components through pipelines to form a vapor compression refrigeration cycle system. When the indoor unit of the vertical air conditioner is in the cooling mode, the heat exchange air flow is cold air; when the indoor unit of the vertical air conditioner is in the heating mode, the heat exchange air flow is hot air. The heat exchange air flows through the first air outlet 12 and is blown to the indoor environment to complete the cooling and heating of the indoor environment.

The second column shell 20 is in the shape of a vertical column, that is, a hollow columnar shell. The second column shell 20 and the first column shell 10 are arranged side by side in the transverse direction. The "horizontal" direction is marked in the figure, and the left and right directions perpendicular to the front and rear directions of the vertical air conditioner indoor unit are the "horizontal directions". A second air outlet 22 is provided on the front side of the peripheral wall of the second column housing 20 . A second air inlet 21 open to the indoor environment is provided in other parts of the peripheral wall of the second column shell 20 to introduce indoor air.

The second fan 24 is disposed in the second column shell 20 and is used to urge the indoor air in the second column shell 20 to be blown out through the second air outlet 22 and then mixed into the heat exchange air flow blown out by the first air outlet 12 to form mixed air. effect. Compared with the heat exchange air flow, the temperature of the mixed air flow is closer to room temperature, the comfort is higher, the wind feels softer, the air volume and wind speed are increased, and the air supply distance is farther.

The appearance difference of existing vertical air conditioner indoor units is not obvious, and the air supply experience is poor, resulting in many complaints from users. Especially when air conditioning is cooling, people often feel that the outlet air temperature is low and the wind speed is high. The cold wind blows directly on the human body, causing discomfort to the user. This is what people often say is that the wind is too "hard" and not soft enough. In addition, there are some double-column vertical air-conditioning indoor units in the field of air conditioning, but their two column shells are used to blow out heat exchange airflow, and the form is very simple. The vertical air conditioner indoor unit of the embodiment of the present invention is designed with a The second column shell 20 juxtaposed with the column shell 10 is specially used to blow out the indoor air, so that the air mixing volume is very large. This structure breaks through the convention and is very novel and ingenious.

In addition, since there is no need to install a heat exchanger in the second column shell 20, the second column shell 20 can be designed to be thinner, making it significantly thinner than the first column shell 10. This asymmetric design just meets the requirement of mixed air. needs, and makes the appearance of the vertical air conditioner indoor unit more novel and unique, improving the competitiveness of the product. For example, the ratio of the width of the second column shell 20 in the transverse direction to the width of the first column shell 10 in the transverse direction can be less than 1/2. The width refers to the distance between the two farthest points of the outer walls on both sides of the second column shell 20 or the first column shell 10 in the transverse direction. The ratio of the depth dimension of the second cylindrical shell 20 along the front-rear direction to the depth dimension of the first cylindrical shell 10 along the front-rear direction is less than 1/2. This dimension refers to the front and rear sides of the second cylindrical shell 20 or the first cylindrical shell 10. The distance between the two furthest points on the outer wall in the front-to-back direction. This makes the size difference between the two large enough to form a differentiated appearance of the two columns.

In some embodiments, as shown in FIGS. 1 and 4 , the second column shell 20 and the first column shell 10 can be arranged at horizontal intervals, so that an air induction gap 13 is formed between them. The front and rear sides of the air induction interval 13 are connected to the indoor environment.

When the vertical air conditioner indoor unit of the embodiment of the present invention is running, the first column housing 10 and the second column housing 20 can be selectively turned on or the air supply can be started at the same time. When the first air outlet 12 and/or the second air outlet 22 discharges air, the negative pressure is used to drive the indoor air in the air induction interval 13 to flow forward, forming an air induction and air mixing effect. The temperature of the mixed air flow is closer to room temperature than the heat exchange air flow, and the comfort is higher, the wind feels softer, the air volume and wind speed are increased, and the air supply distance is farther.

For example, the second air outlet 22 may be in the shape of an integral vertical strip extending from top to bottom, or may also be in the shape of an intermittent vertical strip composed of a plurality of sub-air outlets arranged vertically. In order to match the cross-flow fan and make the cross-flow fan have higher operating efficiency and smaller wind resistance, as shown in Figure 3, a second air duct 25 can be formed in the second column shell 20, and the second air duct 25 is a cross-flow fan. The outlet of the flow duct is connected to the second air outlet 22 , and the second fan 24 is disposed in the second air duct 25 .
