DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1 , Figure 1 Shown is a schematic structural diagram of an air conditioning cabinet 10 provided in an embodiment of the present invention.

[0037] The air conditioning cabinet 10 provided in the embodiment of the present invention includes an air guide mechanism 100, a housing 200, a fan 300 and a condenser 400. The fan 300 and the condenser 400 are respectively arranged in the housing 200, and the fan 300 can be a centrifugal fan. The air guide mechanism 100 is arranged on the back plate of the housing 200 and is between the fan 300 and the condenser 400. The air guide mechanism 100 is used to adjust and change the angle of the airflow from the fan 300 to the condenser 400, thereby adjusting the uniformity of the airflow flow from the fan 300 to the condenser 400, so that the air conditioning cabinet 10 obtains the best heat exchange performance.

[0038] The air guide mechanism 100 includes a bearing 110 and an air guide assembly 130. The air guide assembly 130 is disposed on the bearing 110 and close to the fan 300. The bearing 110 is used to be installed with external equipment. In this embodiment, the bearing 110 can be selected as the back plate of the housing 200 of the air conditioner cabinet 10. In other embodiments, the bearing 110 can be selected as the side plate of the housing 200, or the bearing 110 is disposed on the back plate of the housing 200. In actual applications, the air guide assembly 130 moves relative to the bearing 110 under the action of external force to adjust the angle of the airflow from the fan 300 to the condenser 400.

[0039] See also Figure 2 , Figure 2 The figure shows a schematic diagram of the structure of the air guide assembly 130. The air guide assembly 130 includes a fixing member 131, an air guide member 133, a fixed slide rail 135 and an adjustment assembly 137. The fixing member 131 and the fixed slide rail 135 are both arranged on the bearing member 110. One end of the air guide member 133 is hinged to the fixing member 131. The adjustment assembly 137 is movably connected to the fixed slide rail 135 and the air guide member 133 respectively. The adjustment assembly 137 is used to slide along the fixed slide rail 135 under the action of an external force to drive the air guide member 133 to rotate relative to the fixing member 131 to adjust the angle of the airflow from the fan 300 of the air conditioner cabinet 10 to the condenser 400, and drive the air guide member 133 to expand and contract to adjust the length, so as to adjust the air guide area.

[0040] See also Figure 3 , Figure 3 The figure is a schematic diagram of the structure of the fixing member 131. In this embodiment, the fixing member 131 is fixed to the bearing member 110 by screws, and the fixing member 131 is in the shape of a rectangular plate, and the length of its long side is substantially equal to the width of the back plate of the housing 200. The two wide sides of the fixing member 131 are respectively provided with ear plates 1311 along the lateral direction perpendicular to one side of the fixing member 131, and the two ear plates 1311 are provided with through holes 1313 opposite to each other, which are used for being hinged with the air guide member 133.

[0041] The air guide member 133 includes a first air guide plate 1331 and a second air guide plate 1333. Figure 4 , Figure 4 The figure is a schematic diagram of the structure of the first air guide plate 1331. In this embodiment, the first air guide plate 1331 and the second air guide plate 1333 are both rectangular, and one end of the first air guide plate 1331 in the width direction is provided with two first pins 1332 respectively matched with two through holes 1313 provided on two ear plates 1311 on the fixing member 131, and the two first pins 1332 are respectively protruded on the two wide sides along the extension direction of the long side of the first air guide plate 1331.

[0042] It should be noted that, in other embodiments, the hinged connection between the first air guide plate 1331 and the fixing member 131 can also be achieved by other structural forms. For example, two latches are relatively protruded on the two ear plates 1311 of the fixing member 131, and the two wide sides of the first air guide plate 1331 are respectively recessed with blind holes that cooperate with the two latches, and the two latches are respectively inserted into the two blind holes.

[0043] See also Figure 5 , Figure 5 Shown Figure 4 An enlarged schematic diagram of the area A in the middle. A receiving groove 1334 is recessed on the end surface of the first air guide plate 1331 at one end away from the fixing member 131 in the width direction, and the receiving groove 1334 is used for the second air guide plate 1333 to be inserted, so as to realize the extension and retraction of the second air guide plate 1333 at one end away from the fixing member 131 in the width direction of the first air guide plate 1331.

[0044] In this embodiment, the cross section of the receiving groove 1334 perpendicular to the recessed direction thereof is rectangular, that is, the receiving groove 1334 forms a rectangular receiving cavity. Considering the need to ensure the structural strength of the first air guide plate 1331 during the movement of the second air guide plate 1333 relative to the first air guide plate 1331, the receiving groove 1334 is disposed at the middle position of the end surface of the first air guide plate 1331 in the thickness direction.

[0045] See also Figure 6 , Figure 6 The figure shows a schematic diagram of the structure of the second air guide plate 1333. In this embodiment, the second air guide plate 1333 is also rectangular, corresponding to the rectangular receiving slot 1334. One end of the second air guide plate 1333 in the width direction is inserted into the receiving slot 1334, and can slide along the concave direction of the receiving slot 1334, so as to be extended or retracted from the end of the first air guide plate 1331 away from the fixing member 131.

[0046] It is understandable that in order to facilitate assembly and smooth sliding, the second air guide plate 1333 and the receiving groove 1334 are clearance-matched, that is, the thickness of the second air guide plate 1333 is slightly smaller than the thickness of the receiving groove 1334, and the length of the second air guide plate 1333 is slightly smaller than the length of the receiving groove 1334.

[0047] It should be noted that, in other embodiments, the first air guide plate 1331 and the second air guide plate 1333 may also adopt other relatively slidable connection structures. For example, a plurality of slide rails extending in parallel in the width direction of the first air guide plate 1331 are provided, and a plurality of sliding blocks are protruding on one side of the second air guide plate 1333, and the plurality of slide rails are respectively slidably matched with the plurality of corresponding slide rails.

[0048] In this embodiment, two mounting blocks 1335 are arranged oppositely on one side of the second air guide plate 1333 away from one end of the fixing member 131 in the width direction thereof. The two mounting blocks 1335 are convexly arranged on the side of the second air guide plate 1333. When the second air guide plate 1333 is retracted into the receiving groove 1334, the second air guide plate 1333 is limited to prevent the second air guide plate 1333 from being completely retracted into the receiving groove 1334 and from being extended out of the receiving groove 1334 next time. In addition, first blind holes 1336 are concavely arranged oppositely on two opposite side surfaces of the two mounting blocks 1335. The two first blind holes 1336 are used for being hinged with the adjustment assembly 137.

[0049] Please combine Figure 4 and Figure 6 As shown, a first threaded hole 1337 is provided on one side of the first air guide plate 1331, and the receiving groove 1334 is connected to the outside through the first threaded hole 1337. In practical application, when the second air guide plate 1333 extends to a desired length along the receiving groove 1334, a screw is screwed into the first threaded hole 1337 until the screw enters the receiving groove 1334 and abuts against the side of the second air guide plate 1333, thereby completing the relative locking of the second air guide plate 1333 and the first air guide plate 1331, that is, completing the positioning of the second air guide plate 1333; when it is necessary to adjust the extension of the second air guide plate 1333 relative to the first air guide plate 1331 again, the screw in the first threaded hole 1337 is screwed out until the screw is out of contact with the second air guide plate 1333, thereby completing the unlocking of the second air guide plate 1333, and the extension of the second air guide plate 1333 relative to the first air guide plate 1331 can be adjusted again.

[0050] The adjustment assembly 137 includes a rotating member 1371 and a sliding member 1373, see Figure 7 and Figure 8 , Figure 7 FIG. 1 is a schematic diagram showing the structure of the rotating member 1371 in the adjusting assembly 137. Figure 8 The figure shows a schematic diagram of the structure of the sliding member 1373 in the adjustment assembly 137. The sliding member 1373 is slidably matched with the fixed slide rail 135, and under the action of external force, the sliding member 1373 can slide along the fixed slide rail 135. One end of the rotating member 1371 is hinged to the sliding member 1373, and one end of the rotating member 1371 away from the sliding member 1373 is rotatably matched with two first blind holes 1336 that are relatively concavely arranged on two mounting blocks 1335 that are convexly arranged on the second air guide plate 1333.

[0051] In this embodiment, the rotating member 1371 is generally in a rectangular plate-shaped structure, and two second pins 1372 are respectively protruded along the long side direction on one end of the two wide sides thereof, and the sizes of the two second pins 1372 match the sizes of the two first blind holes 1336 recessed on the mounting block 1335 provided on the second air guide plate 1333. The two second pins 1372 are respectively inserted into the two first blind holes 1336 and are in gap fit with the mounting holes. In practical applications, the two second pins 1372 can rotate in the two first blind holes 1336, that is, the rotating member 1371 can rotate relative to the second air guide plate 1333 under the action of an external force.

[0052] The rotating member 1371 has a mating notch 1374 recessed at one end away from the two latches in the width direction thereof, and two second blind holes 1375 are relatively recessed on the two opposite side walls of the mating notch 1374 in the length direction of the rotating member 1371. The sliding member 1373 is provided with two third pins 1376, which are respectively inserted into the two second blind holes 1375 and are clearance-matched with the second blind holes 1375, that is, the rotating member 1371 can rotate relative to the sliding member 1373.

[0053] See also Figure 8 and Fig. 9 , Fig. 9 The figure shows a schematic diagram of the structure of the fixed slide rail 135. The fixed slide rail 135 includes two track bars 1351 laid in parallel, and two opposite sides of the two track bars 1351 are concavely provided with slide grooves 1352, and the slide grooves 1352 extend along the extension direction of the track bars 1351. Two opposite sides of the sliding member 1373 are respectively provided with sliding protrusions 1377, and the two sliding protrusions 1377 are respectively slidably matched with the two slide grooves 1352, and the sliding member 1373 is spanned between the two track bars 1351 through the two sliding protrusions 1377.

[0054] A plurality of second threaded holes 1353 are also provided at intervals on the two track bars 1351, and the slide groove 1352 is connected to the outside through the second threaded holes 1353. In practical applications, when the sliding member 1373 slides to any position relative to the fixed slide rail 135, the sliding member 1373 can be locked by screwing a screw into the second threaded hole 1353 at the corresponding position until the screw enters the slide groove 1352 and abuts against the sliding member 1373. When the position of the sliding member 1373 needs to be adjusted relative to the fixed slide rail 135 again, the screw is unscrewed until the screw is out of contact with the sliding member 1373, and the sliding member 1373 is unlocked.

[0055] It should be noted that in order to ensure that the relative rotation and sliding of each component can be carried out smoothly without jamming under the action of external force, in this embodiment, the extension direction of the fixed slide rail 135 and the sliding direction of the second air guide plate 1333 relative to the first air guide plate 1331 are both in the plane of rotation of the first air guide plate 1331 relative to the fixed member 131.

[0056] In actual application, when the air conditioning cabinet 10 provided in this embodiment starts to operate, the wind blown by the fan 300 changes its flow direction through the guiding effect of the air guide 133 and reaches the condenser 400. Keep the machine turned on, constantly adjust the angle between the first air guide plate 1331 and the fixing member 131, and the extension length of the second air guide plate 1333 from the end of the first air guide plate 1331 away from the fixing member 131, and record the heat exchange performance of the air conditioning cabinet 10 at the same time. After a limited number of adjustment records, the air guide plate state corresponding to the best heat exchange performance of the air conditioning cabinet 10 can be found, and then screw in the screws through the first threaded hole 1337 and the second threaded hole 1353 respectively to fix the structure.

[0057] In summary, the air guide mechanism 100 has the characteristic of being able to adjust the direction of the airflow blowing toward the condenser 400, thereby improving the heat exchange performance of the air conditioning cabinet 10. Therefore, the air conditioning cabinet 10 provided in the embodiment of the present invention has adjustable heat exchange performance and better user experience.

[0058] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
