When a feature "comprises or includes" a feature or some of its coverage, this indicates that other features are not excluded and may further include other features, unless expressly stated otherwise.

In the description of the present embodiment, the descriptions of the terms "one embodiment," "some embodiments," "some examples," "one example," and the like mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

The embodiment of the utility model provides a vertical air conditioner indoor unit 10, wherein the vertical air conditioner indoor unit 10 is an indoor part of a vertical air conditioner. Air conditioners are used for conditioning indoor air, including adjusting the temperature, humidity, air quality of the air, humidifying the indoor air, dehumidifying, introducing fresh air, and the like.

Fig. 1 is a transverse cross-sectional view of a stand air conditioner indoor unit 10 according to one embodiment of the present utility model, and referring to fig. 1, a stand air conditioner may generally include a cabinet 100, a heat exchanger, and a cross-flow fan 200. Wherein, the housing 100 defines an accommodating space to accommodate the heat exchanger and the cross-flow fan 200, a front panel is disposed on the front side of the housing 100, and an air outlet extending vertically is disposed on the front panel. An air inlet is opened at the rear side of the cabinet 100. Specifically, the rear side of the casing 100 may be an air inlet grille, and an air inlet is provided on the air inlet grille. The heat exchanger is disposed in the casing 100, and forms a vapor compression refrigeration cycle together with a compressor, a condenser, a throttling device, a connecting pipeline and other accessories, so as to realize refrigeration/heating of the air conditioner, and the specific principle and structure are not repeated herein.

During operation of the air conditioner, a conditioning airflow for conditioning indoor air is formed in the cabinet 100. The conditioning airflow may specifically be a heat exchange airflow, which is used to regulate the temperature of the indoor environment. When the air conditioner is in a refrigerating mode, the heat exchange airflow is cold air; when the air conditioner is in a heating mode, the heat exchange airflow is hot air. Of course, if the air conditioner has additional conditioning functions such as purifying, fresh air, humidifying, etc., the conditioning airflow may also include purifying airflow, fresh air airflow, humidifying airflow, etc.

In the embodiment shown in the drawings of the present utility model, the indoor unit 10 of the stand air conditioner is a cabinet unit of a double-column air conditioner. An air duct assembly is arranged in the casing 100, and two left and right air outlet air ducts are formed in the casing 100 by the air duct assembly. The number of the cross-flow fans 200 is two, and the two cross-flow fans 200 are arranged in the two air outlet air channels at intervals along the transverse direction.

The number of the air inlets and the air outlets can be two, and each air outlet air channel is correspondingly communicated with one air inlet and one air outlet. The two cross flow fans 200 may be operated independently or simultaneously to provide different outlet patterns to the user. Two vertical air deflectors 300 can be arranged in each air inlet, and each vertical air deflector 300 can swing around a rotating shaft in the vertical direction, so that fixed-angle air outlet or swing air sweeping of the air conditioner is realized.

Referring to fig. 1, the duct assembly may include two first partitions 410, two second partitions 420, and two third partitions 430. The two first partitions 410 are symmetrically disposed between the two through-flow fans 200, the two second partitions 420 are disposed at the front sides of the two first partitions 410, and the two third partitions 430 are disposed at the outer sides of the two second partitions 420. The first, second and third partitions 410, 420 and 430 of each side together define an outlet air duct of that side.

Referring to fig. 2 to 4, the air duct assembly may further include a middle partition plate 440, and the middle partition plate 440 is disposed between the two first partition plates 410, for separating the air flows flowing in from the two air inlets into the two air outlet air ducts, improving uniformity of air distribution, and preventing the air from flowing in from the two air inlets.

In the foregoing, the air duct partition plate of the current double-column air conditioner is of a symmetrical structure, and needs to be disassembled independently, otherwise, the mold can have problems of sharp iron, thin iron and the like. Specifically, if the problem of sharp steel occurs, the life of the mold is shortened, and the mold is easily scratched by the mold manufacturer and the mold user. If the problem of thin iron occurs, the service life of the die is shortened, because the thin die steel is impacted by molten plastic liquid during injection molding, the thin steel is easy to deform, and the injection molded product is incorrect in size after deformation.

To solve the above-described problem, in the present embodiment, the intermediate separator 440 is biased between the two first separators 410, and the intermediate separator 440 is connected to the biased first separators 410. In this way, the tip can be prevented from being formed at the junction of the front ends of the two first separators 410, thereby avoiding sharp corners on the mold, improving the wear resistance of the mold, reducing maintenance cost and reducing the risk of being scratched.

The offset distance between the middle spacer 440 and the symmetry plane of the two first spacers 410 may be 2-4 times the thickness of the middle spacer 440. If the offset distance is too small, the problem of die tip iron can exist to a certain extent, and if the offset distance is too large, the air quantity difference of the two air outlet air channels is large, so that uniform air outlet of the air conditioner is not facilitated.

Preferably, the middle partition 440 and the two first partitions 410 may be integrally formed. In this way, the middle partition plate 440 and the two first partition plates 410 can be processed and implemented in a set of dies, which is beneficial to reducing the die cost and improving the convenience of assembly.

A wing 450 may be provided between the middle spacer 440 and the first spacers 410 on both sides. The wing plates 450 may improve stability between the middle separator 440 and the first separator 410, so that the connection between the middle separator 440 and the first separator 410 is not easily broken, which is beneficial to prolonging the service life thereof.

Further, the number of the wing plates 450 may be plural, and the plurality of wing plates 450 may be spaced apart between the middle partition 440 and the first partition 410 in the height direction of the cabinet 100. The stability between the middle partition board 440 and the first partition board 410 can be obviously improved in this way, so that deformation is not easy to occur between the first partition board 410 and the middle partition board 440, and the phenomenon of unstable structure caused by long-term blowing can be effectively avoided.

A rib 460 is provided between the middle spacer 440 and the first spacer 410 away therefrom, and the rib 460 may extend in the height direction of the casing 100. The rib plates 460 can be connected with the adjacent first partition plates 410 and the middle partition plate 440 through the wing plates 450, so that the stress of the two first partition plates 410 and the middle partition plate 440 is more uniform, and the structure is kept stable.

In one example, the rib 460 and the middle partition 440 may be symmetrical about the symmetry plane of the two first partitions 410, so that the stress degrees of the first partition 410 and the second partition 420 are uniform during the air outlet process of the air conditioner.

The rib 460 may have a height of 1/8 of the height of the middle barrier 440, which may be disposed only in the top region of the middle barrier 440 and the first barrier 410, may be disposed in the bottom region of the middle barrier 440 and the first barrier 410, and may be disposed in the top region and the bottom region of the middle barrier 440 and the first barrier 410, respectively. The rib 460 is shown disposed only in the bottom regions of the septum 440 and the first septum 410 to minimize the weight of the air duct assembly. On the premise of guaranteeing the structural strength, the processing cost is reduced.

Because the two first partitions 410 in this embodiment are gradually expanded from front to back, sharp corners are easily formed on the mold cavity, stress concentration is easily generated when the sharp corner is stressed, the sharp corner is easily broken, and the sharp corner is easily worn and damaged, resulting in increased maintenance cost.

To solve this problem, the duct assembly may further include a connection plate 470, and referring to fig. 5, the connection plate 470 is connected between the front sides of the two first partitions 410. The connection plate 470 can increase the front side distance between the two first spacers 410, so that the two first spacers 410 are easier to be removed from the mold, and the blocking phenomenon is avoided.

The lateral width of the connection plate 470 may be 2-4 times the thickness of the first partition 410, so as to ensure that the front side spacing between the two first partition 410 can meet the demolding requirement.

The connection plate 470 may be integrally formed with the two first partitions 410 and have rounded corners at the connection points, so as to avoid the problems of sharp iron, thin iron, etc. of the grinding tool.

According to any one of the optional embodiments or the combination of multiple optional embodiments, the following beneficial effects can be achieved according to the embodiment of the utility model:

According to the vertical air conditioner indoor unit 10, the partition plates 440 are offset between the two first partition plates 410, so that the front end connection parts of the two first partition plates 410 can be prevented from forming sharp points, sharp corners on a die are avoided, the wear resistance of the die is improved, the maintenance cost is reduced, and the risk of being scratched is reduced.

Further, in the vertical air conditioner indoor unit 10 of the present utility model, the middle partition plate 440 and the two first partition plates 410 are configured as an integral structure, so that the middle partition plate 440 and the two first partition plates 410 can be processed and implemented in a set of mold, which is beneficial to reducing the mold cost and improving the convenience of assembly.

Further, in the vertical air conditioner indoor unit 10 of the present utility model, the stability between the middle partition board 440 and the first partition board 410 can be improved by the wing board 450, so that the connection between the middle partition board 440 and the first partition board 410 is not easy to break, which is beneficial to prolonging the service life thereof.

Further, in the vertical air conditioner indoor unit 10 of the present utility model, by disposing the connection plate 470 between the front sides of the two first partitions 410, the interval between the front sides of the two first partitions 410 can be increased, so as to avoid the front sides of the two first partitions 410 from forming sharp corners, which is beneficial to improving the smoothness of mold stripping and preventing adhesion.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model.
