Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a multi-inlet / outlet air conditioning unit. Background Technology

[0002] Traditional floor-standing air conditioners typically have an air inlet at the back and an air outlet at the front. Air enters from the rear, is heated by the heat exchanger, and is then blown out by a single cross-flow fan. However, this type of single-inlet and single-outlet floor-standing air conditioner is no longer sufficient to meet market demands, and its air delivery method is relatively fixed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an air conditioner cabinet unit with multiple air inlets and outlets, so as to solve the problem that the existing technology, which has a fixed method of setting an air inlet on the back of the unit and an air outlet on the front for air supply, is no longer able to meet the needs of the market.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-air-inlet and multi-outlet air conditioner unit, comprising a body and a fan assembly disposed within the body for providing airflow power, wherein the body is assembled from a front frame assembly and a rear frame assembly along the front-rear direction, and the rear frame assembly is provided with an air inlet that cooperates with the fan assembly, and the front frame assembly is provided with an air outlet that cooperates with the fan assembly.

[0005] The number of air inlets is not less than two and both are located in the first non-rear area of ​​the fuselage. The first non-rear area includes the first lateral area on the rear frame assembly.

[0006] The number of air outlets is not less than two, and both are located in the second non-rear area of ​​the body. The second non-rear area includes the second lateral area and the front area on the front frame assembly.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] This air conditioner unit has at least two air inlets and at least two air outlets.

[0015] The present invention will be further described in detail below through specific embodiments:

[0016] The current method of air conditioning unit placement, with an air inlet on the back and an air outlet on the front, is relatively fixed and no longer meets market demands. To address this issue, such as... Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown in the figure, this utility model embodiment proposes an air conditioner cabinet unit with multiple air inlets and outlets, including a body and a fan assembly disposed within the body for providing airflow power. The body is assembled from a front frame assembly 1 and a rear frame assembly 2 along the front-rear direction, with an air inlet 5 on the rear frame assembly 2 that cooperates with the fan assembly, and an air outlet on the front frame assembly 1 that cooperates with the fan assembly. The number of air inlets 5 is not less than two, and both are disposed in a first non-rear area of ​​the body, which includes a first lateral area on the rear frame assembly 2. The number of air outlets is not less than two, and both are disposed in a second non-rear area of ​​the body, which includes a second lateral area and a front area on the front frame assembly 1.

[0017] This air conditioner unit has at least two air inlets 5 and at least two air outlets. The air inlets 5 are all arranged in the first lateral area on the rear frame assembly 2, and the air outlets are all arranged in the second lateral area and the front area on the front frame assembly 1, so as to make the air supply mode of this air conditioner unit more diverse and better meet market demand.

[0018] like Figure 1 , Figure 3 as well as Figure 4 As shown, according to another embodiment of the present invention, the multi-inlet and multi-outlet air conditioner unit has a square cross-section for the front frame assembly 1 and a semi-cylindrical cross-section for the rear frame assembly 2.

[0019] In this embodiment, the front frame assembly 1 is specifically a square shell, and the rear frame assembly 2 is a semi-cylindrical shell. That is, the entire body is formed by uniformly splicing the front square shell and the rear semi-cylindrical shell with the same diameter.

[0020] like Figure 4 As shown, according to another embodiment of the present invention, the air conditioner cabinet unit with multiple air inlets and outlets includes a fan assembly comprising at least one centrifugal fan 3, wherein the at least one centrifugal fan 3 is coupled with at least two air outlets in the centrifugal duct within the unit body along either the upper air outlet direction or the lower air outlet direction of the centrifugal duct; the at least one centrifugal fan 3 is coupled with the air inlet 5 along its air inlet direction.

[0021] In this embodiment, after the centrifugal fan 3 is running, a suction force is generated at each air inlet 5 to draw air into the centrifugal duct. Then, the centrifugal fan 3 distributes the air in the centrifugal duct along the upward and downward air outlet directions. The distribution of the air outlets makes the air volume distribution of the air conditioner cabinet unit more reasonable and meets the usage requirements.

[0022] Based on the above solution:

[0023] The fan assembly includes two centrifugal fans 3, and the minimum distance between the two centrifugal fans 3 is less than the diameter of the larger of the two centrifugal fans 3.

[0024] In this embodiment, the two centrifugal fans 3 are arranged side by side in the vertical direction in the centrifugal duct. The minimum distance between the two centrifugal fans 3 is the distance between the lowest point of the bottom of the upper centrifugal fan 3 and the highest point of the top of the lower centrifugal fan 3. The cooperation of the two centrifugal fans 3 in the centrifugal duct helps to accelerate the flow of air and achieve air delivery over a wider area and a longer distance.

[0025] If the distance between the two centrifugal fans 3 is too close, they will interfere with each other and increase the noise level. If the distance between the two centrifugal fans 3 is too far, the air inlet 5 will be too close to both ends of the evaporator inside the unit, affecting the uniformity of air distribution, resulting in uneven heat exchange of the evaporator, reduced heat exchange efficiency, and affecting the air conditioning performance.

[0026] like Figure 3 As shown, according to another embodiment of the present invention, the first lateral region of the multi-inlet and multi-outlet air conditioner is defined as: within a range of 0.05L to 0.9L from C to the front panel of the front frame assembly 1; wherein, the width of the unit is set as W from the top view of the unit, the depth of the unit at 1 / 2W of the width of the unit is L, and the intersection of the center line at 1 / 2W of the width of the unit and the rear frame assembly 2 is C.

[0027] Here, by defining the first lateral area as described above, the air inlet 5 is arranged on the rear side of the front frame assembly 1. When the air conditioner unit is arranged directly against the wall, the air intake of the air inlet 5 will not be blocked by the wall, ensuring a considerable air intake volume. At the same time, the back of the air conditioner unit can be placed closer to the wall or in a corner, saving indoor space.

[0028] like Figure 4 As shown, according to another embodiment of the present invention, the second lateral region of the multi-inlet and multi-outlet air conditioner is defined as: within a range of 0.08L to 0.425L from D in the direction of the rear frame assembly 2; the body width is set as W from the top view of the body, the body depth at 1 / 2W of the body width is set as L, and the intersection of the center line at 1 / 2W of the body width and the front frame assembly 1 is set as D.

[0029] The positive area is defined as: the area directly in front of the front frame component 1 with an angle of 0 with the vertical plane.

[0030] In this embodiment, the area on the body where the second lateral or frontal region is arranged not only forms multiple air outlets, but also has a considerable air delivery distance and volume.

[0031] Furthermore, the positive area along the vertical direction is further defined as: the area between 50mm below the bottom of the heat exchanger 4 arranged inside the unit and the top of the front frame assembly 1. This restricts the relative position of the bottom of the air conditioner unit and the heat exchanger 4. Firstly, the lower air outlet cannot be too close to the ground, causing airflow obstruction and resulting in a stronger wind on the ground that stirs up dust. Secondly, the distance between the lower and upper air outlets cannot be too far, otherwise the airflow will be too dispersed, making it more difficult to achieve a unified airflow effect.

[0032] According to another embodiment of the present invention, in the multi-air-inlet and multi-outlet air conditioner unit, a display panel is provided on the front frame assembly 1, and the distance between the display panel and any one of the air outlets is not less than 80mm.

[0033] In this embodiment, for example, the distance between the display panel and any air outlet is 80mm, 90mm, 100mm or 110mm, to ensure that the installation position of the display panel on the front frame assembly 1 has sufficient structural strength and that the display panel can be stably installed on the front frame assembly 1.

[0034] like Figure 2As shown, according to another embodiment of the present invention, the air conditioner cabinet unit with multiple air inlets and outlets has two air inlets 5 symmetrically distributed in the first lateral region, and at least one air outlet in each of the upper left region, lower left region, upper right region, and lower right region of the second lateral region, as well as in the upper forward region and lower forward region of the forward region.

[0035] In this embodiment, the air inlets 5 are symmetrically distributed in the left rear side area and the right rear side area of ​​the rear frame assembly 2. The front frame assembly 1 includes a front panel located on the front side, side panels provided on both sides behind the front panel, and a sloping plate that is transitionally connected to the corresponding side of the front panel in each side panel. The display panel is disposed on the front panel.

[0036] The upper positive area is located on the front panel above the centrifugal fan 3, and the lower positive area is located on the front panel below the centrifugal fan 3. The upper left and upper right areas are correspondingly distributed on the two side panels above the centrifugal fan 3, and the lower left and lower right areas are correspondingly distributed on the two side panels below the centrifugal fan 3, thus achieving a reasonable distribution. Each of the upper left, lower left, upper right, lower right, upper positive, and lower positive areas has an air outlet, resulting in an upper positive air outlet 6, a lower positive air outlet 7, an upper left air outlet 8, a lower left air outlet 9, an upper right air outlet, and a lower right air outlet, forming a continuous annular wraparound air outlet to achieve wider and longer-distance air delivery.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
