The embodiment of the utility model provides an in, because each air outlet setting can be to left right direction air supply in the horizontal both sides of casing 10, changed traditional wall-hung machine and only be good at the defect of air supply forward. After the air supply airflow is diffused leftwards and rightwards respectively and reaches the walls on the left side and the right side of the room, the air supply airflow slowly bypasses to the space in front of the indoor unit of the vertical wall-mounted air conditioner, an encircling air supply effect is formed, and discomfort caused by direct blowing of cold air or hot air to a human body is avoided.
Moreover, because the length direction of the shell 10 is along the vertical direction, the openable areas of the surfaces of the rear wall, the left side wall and the right side wall of the shell 10 are large, so that the air inlet area and the air outlet area of the whole vertical wall-mounted air conditioner indoor unit are large, air inlet and outlet are smooth, large-air-volume air supply is facilitated, and quick refrigeration/heating is realized. And, the utility model discloses a vertical hanging air conditioning indoor set is special to establish a wind channel and introduces outdoor new trend, has realized the exchange of indoor outdoor air, is favorable to keeping the new freshness of indoor air.
In some embodiments, as shown in fig. 1-5, the volute 20 and the rear wall of the housing 10 may define two isolated chambers 111, 112 (separated by the partition 103). The indoor unit of the vertical wall-mounted air conditioner further comprises a fresh air pipe 80, the fresh air pipe 80 is inserted into one chamber 112 to introduce outdoor fresh air into the chamber 112, and the chamber 112 is communicated with an inlet 221 of one air duct 22. For example, as shown in fig. 5, the fresh air duct 80 may include a square insertion portion 81, the housing 10 may be provided with the insertion port 17, and the square insertion portion 81 may be inserted into the insertion port 17. The other chamber 111 is communicated with the inlet 211 of the other air duct (air duct 21), the heat exchanger 40 is installed in the chamber 111, and the air inlet 11 is opened on the rear wall of the housing 10 corresponding to the chamber 111. The heat exchanger 40 may have a flat plate shape with a normal line extending in the front-rear direction to make the inner structure of the case 10 more compact.
Specifically, as shown in fig. 1 to 5, the number of the first air outlet, the second air outlet, the air duct, and the centrifugal fan may be two. The centrifugal fan 31 is disposed in the air duct 21, the air duct 21 has an inlet 211 and two outlets 212, and the two outlets 212 respectively face the first air outlet 12 and the second air outlet 14. The centrifugal fan 32 is disposed in the air duct 22, and the air duct 22 has an inlet 221 and two outlets 222, and the two outlets 222 face the first air outlet 13 and the second air outlet 15, respectively.
The embodiment of the utility model provides a make new trend and heat exchanger branch be in isolated two cavities, the different air outlets of difference centrifugal fan and wind channel direction are do not divided to the subdividing, make heat exchange wind and new trend keep independent, each other do not influence. Therefore, when the fresh air function needs to be suspended, the corresponding centrifugal fan is directly closed, and the generation and the transmission of the heat exchange air are not influenced.
In some embodiments, as shown in fig. 1 to 5, the plurality of first air outlets 12, 13 and the plurality of second air outlets 14, 15 are arranged in a staggered manner in the vertical direction. That is, the height position of each first air outlet is different from the height position of any one of the second air outlets. For example, as shown in fig. 2, the housing 10 has two first air outlets 12, 13 and two second air outlets 14, 15, and the height position of the second air outlet 14 is lower than that of the first air outlet 12 and higher than that of the first air outlet 13; the height position of the second air outlet 15 is lower than that of the first air outlet 13, so that the air outlets are arranged in a staggered mode in the vertical direction. This causes the air supply flows on both lateral sides of the casing 10 to be blown out in a staggered manner in the vertical direction, forming a multi-dimensional air supply effect, expanding the air supply height range, and accelerating the cooling/heating speed.
In some embodiments, as shown in fig. 1 to 5, the housing 10 may be flat with a length direction parallel to the vertical direction, a width direction parallel to the transverse direction, and a thickness direction parallel to the front-rear direction, so as to make the machine body thinner and occupy less space. Because the vertical wall-mounted air conditioner indoor unit occupies smaller space, the installation position of the vertical wall-mounted air conditioner indoor unit can be properly reduced, so that downward air supply is facilitated, and the heating speed is increased. And the flat appearance of the vertical wall-mounted air conditioner indoor unit is novel and attractive, and the product grade is improved.

Moreover, the structural characteristics of axial air inlet and radial air outlet of the centrifugal fans 31 and 32 are perfectly matched with the air flow trend of lateral air inlet and lateral air outlet of the shell 10, and the fan efficiency is higher. Therefore, the utility model discloses structural design is very ingenious. In addition, due to the fact that the centrifugal fans 31 and 32 are arranged, the opening number of the centrifugal fans 31 and 32 can be selected according to air volume requirements of the vertical wall-mounted air conditioner indoor unit, and the control mode of the air volume is enriched.
In addition, because the vertical wall-mounted air conditioner indoor unit further comprises the electric cabinet 70, the electric cabinet 70 can be arranged in the air ducts 21 and 22, so that the electric cabinet does not occupy extra thickness space, and the influence on the flat structure of the shell 10 is avoided.
In some embodiments, as shown in fig. 5, the volute 20 includes a rear shell 201 and a front shell 202. The rear case 201 is formed with inlet ports 211, 221, and the front case 202 covers the front side of the rear case 201 to define a cavity therewith, and left and right sides are formed with outlet ports 212, 222. One or more partitions are provided between the front case 202 and the rear case 201 to partition the plurality of air paths 21, 22. As shown in fig. 5, if the number of the air ducts 21 and 22 is two, only one spacing portion 203 needs to be provided. The spacer 203 may be integrally formed with the rear case 201. The centrifugal fan 31 includes a motor 311 and a motor cover 312 to be mounted to the front case 202. The centrifugal fan 32 includes a motor 321 and a motor cover 322 to be mounted to the front case 202.
In some embodiments, a wind guiding mechanism is disposed at each of the first air outlets 12, 13 and each of the second air outlets 14, 15, and the wind guiding mechanism is mounted on the volute 20 for guiding the wind direction. Specifically, as shown in fig. 1 to 5, the wind guiding mechanism is a swing blade set 60 for swinging wind up and down. Furthermore, in some alternative embodiments, the wind guiding structure may also be a wind guiding plate rotatable about a vertical axis. Or, the swinging blades can be arranged at part of the air outlets, and the air guide plates can be arranged at other air outlets.
The embodiment of the utility model provides an install wind guiding mechanism in spiral case 20, make casing 10's structure further simplify. For example, referring to fig. 5, the casing 10 includes a rear cover 101 and a front cover 102, the rear cover 102 is opened with the air inlet 11, and the front cover 101 is opened with the first air outlets 12 and 13 and the second air outlets 14 and 15.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments have been illustrated and described in detail herein, many other variations or modifications can be made in accordance with the principles of the invention, as may be directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
