The utility model provides a vertical air conditioner indoor unit. The vertical air conditioner indoor unit is the indoor part of the split air conditioner, which is used to adjust the indoor air, such as cooling/heating, dehumidification, introducing fresh air, etc. The vertical air conditioner indoor unit can be a conventional floor-standing cabinet or a vertical wall-mounted unit.

Fig. 1 is a schematic front view of a vertical air conditioner indoor unit according to an embodiment of the present invention, Fig. 2 is a schematic left view of Fig. 1, Fig. 3 is an enlarged N-N sectional view of Fig. 1, and Fig. 4 is an enlarged view of Fig. 2 It is a schematic diagram showing a vertical air conditioner indoor unit when both the first air guide part and the second air guide part guide the air forward. Figure 4 shows the flow direction of the heat exchange air flow with solid arrows, and the flow direction of indoor air with hollow arrows.

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 cylindrical shell 10 is in the shape of a vertical column, that is, a hollow cylindrical shell. A first air outlet 12 for blowing out heat exchanging air is opened on the front side of the first column shell 10 . The first air outlet 12 is opened 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 compressor, the heat exchanger of 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 airflow is cold air; when the indoor unit of the vertical air conditioner is in the heating mode, the heat exchange airflow is hot air. The heat exchange air is blown to the indoor environment through the first air outlet 12 to complete the cooling and heating of the indoor environment.

The second cylindrical shell 20 is in the shape of a vertical column, that is, a hollow cylindrical shell. The second column case 20 is arranged side by side with the first column case 10 along the transverse direction. The "horizontal" has been marked in the figure, and the left-right direction perpendicular to the front-to-back direction of the vertical air conditioner indoor unit is the "horizontal". A second air outlet 22 is defined on the front side of the peripheral wall of the second column shell 20 . Other parts of the peripheral wall of the second column shell 20 are provided with a second air inlet 21 open to the indoor environment to introduce indoor air.

The second blower 24 is arranged in the second column shell 20, and is used to promote 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 airflow blown out by the first air outlet 12 to form mixed air. effect. Compared with the heat exchange airflow, the temperature of the mixed airflow is closer to the room temperature, with higher comfort and softer wind feeling, which also increases the air volume and wind speed, and the air supply distance is longer.

The appearance difference of the existing vertical air conditioner indoor units is not obvious, and the air supply experience is not good, causing many complaints from users. Especially when the air conditioner is cooling, it is often felt that the temperature of the air outlet is low and the wind speed is high, and the cold wind blows directly on the human body, causing the user to feel uncomfortable. That is to say, 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 both of the two column shells are used to blow out heat-exchanging air, and the form is very simple. However, the indoor unit of the vertical air conditioner in the embodiment of the utility model is designed with a second column shell 20 juxtaposed with the first column shell 10, which is specially used to blow out indoor air, so that the mixed air volume is very large.

It also makes the appearance of the vertical air conditioner indoor unit more novel and unique, which improves the competitiveness of the product. For example, the ratio of the width of the second cylindrical case 20 in the lateral direction to the width of the first cylindrical case 10 in the lateral direction may be made smaller than 1/2. The width refers to the distance between two points on the outer walls of the second cylindrical shell 20 or the first cylindrical shell 10 in the lateral direction that are farthest from each other in the lateral direction. The ratio of the depth dimension of the second column case 20 along the front-to-rear direction to the depth dimension of the first column case 10 along the front-to-rear direction is less than 1/2, which refers to the front and rear sides of the second column case 20 or the first column case 10 The distance between the two furthest points of the outer wall in the front-to-back direction. In this way, the size difference between the two is large enough to form a differentiated appearance of double columns.

This vertically arranged cross-flow fan is suitable for the second vertical air outlet 22 . For example, the second air outlet 22 may be in the shape of an integral vertical bar extending from top to bottom, or may also be in the shape of an intermittent vertical bar formed by a plurality of sub-air outlets arranged vertically. In order to match with the cross-flow fan and make the operation efficiency of the cross-flow fan higher and the wind resistance smaller, as shown in FIG. The outlet of the air flow channel communicates with the second air outlet 22 , and the second fan 24 is arranged in the second air channel 25 .
