Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an air guiding structure, an indoor unit, and an air conditioner. Background Technology

[0002] An air conditioner, or air conditioner, is a small air conditioning device consisting of four parts: a refrigeration (heating) circulation system, an air circulation and ventilation system, an electrical control system, and a housing. It maintains a certain temperature, humidity, airflow speed, cleanliness, and freshness of the air in the regulated space. Among them, wall-mounted air conditioners are the mainstream of household air conditioners and have entered thousands of households.

[0003] Since wall-mounted air conditioners are usually installed on the upper part of the room wall, in order to pursue a larger air guiding range, some existing wall-mounted air conditioners usually use a push-out mechanism to push the air guide plate out of the air outlet, and then use a drive mechanism to drive the air guide plate to rotate. The structure is complicated, resulting in low air conditioner installation efficiency and high cost. Utility Model Content

[0031] like Figures 1-5 As shown, this utility model provides an air guiding structure, which is disposed on the body. The body includes a middle frame 200 and a front panel 100 covering the middle frame 200. An air outlet 230 is formed on the middle frame. The air guiding structure includes an air guide plate 300 and a receiving cavity 220 formed by the front panel 100 and the middle frame 200. The air guide plate 300 is rotatably connected to the receiving cavity 220. The air guide plate 300 includes an air guide plate 300 body and a second arc portion 310. The second arc portion 310 has a first position where it is housed in the receiving cavity when it rotates with the air guide plate 300 body to the position where the air outlet 230 is closed, and a second position where it closes the rotation notch 221 when it rotates with the air guide plate 300 body to the position where the front panel 100 is in front.

[0032] The front side of the front panel 100 is the side of the front panel 100 that is away from the middle frame 200. When the air guide plate 300 is rotated to the front side of the front panel 100, the air guide plate 300 is almost perpendicular to the front panel 100 so that there are no obstructions in the air outlet 230's air outlet path, thereby increasing the air outlet range and air guide range.

[0033] When the second arc portion 310 rotates to the second position, the second arc portion 310 covers the rotation gap 221 in the horizontal direction to close the rotation gap 221.

[0034] It is understandable that the air guiding structure forms a receiving cavity 220 with a rotation notch 221 by setting the middle frame 200 to cooperate with the front panel 100, and setting an air guiding plate 300 with an air guiding plate 300 body and a second arc portion 310, and the air guiding plate 300 is rotatably connected to the receiving cavity 220, so that the second arc portion 310 can rotate in a first position and a second position, so that it is housed in the receiving cavity 220 and the rotation notch 221 is closed. This simplifies the air guiding structure and allows the air guiding plate 300 to rotate between the closed air outlet 230 position and the front side of the front panel 100, so that the air guiding plate 300 has a large air guiding range.

[0035] In some embodiments, the air guide structure further includes a first arc portion 110, which is formed at the bottom end of the front panel 100. The first arc portion 110 cooperates with the middle frame 200 to form a receiving cavity 220 with a rotation notch 221. The first arc portion 110 and the second arc portion 310 are arranged with the same center. The arc radius of the second arc portion 310 is larger than the arc radius of the first arc portion 110. The second arc portion 310 is configured to rotate from the receiving cavity 220 to the front side of the front panel 100 with its center as the rotation center, so that the air guide plate 300 body can rotate from the closed position closed with the air outlet 230 to the front side of the front panel 100.

[0036] Since the radius of the second arc portion 310 is larger than that of the first arc portion 110, the second arc portion 310 can rotate around the first arc portion 110 with its center as the rotation center. This allows the second arc portion 310 to rotate around the first arc portion 110 to the front side of the front panel 100, giving the air guide plate 300 body a larger rotation angle, allowing the air guide plate 300 body to rotate from the closed position to the front side of the front panel 100.

[0037] The front panel 100 is generally a straight plate structure, which covers the middle frame 200 and is located above the air outlet 230. The first arc part 110 at its bottom is also located above the air outlet 230, that is, the rotation center of the air guide plate 300 is also located above the air outlet 230.

[0038] The first arc portion 110 is fitted with the middle frame 200 at a certain distance to form a receiving cavity 220 with a rotation notch 221, so that the second arc portion 310 can rotate out of the receiving cavity 220 through the rotation notch 221.

[0039] The second arc portion 310 can rotate from the receiving cavity 220 to the front side of the front panel 100 via the rotation notch 221, and can also rotate from the front side of the front panel 100 back into the receiving cavity 220 via the rotation notch 221.

[0040] It is understood that by setting a first arc portion 110 at the bottom of the front panel 100 and cooperating with the middle frame 200 to form a receiving cavity 220, the arc radius of the second arc portion 310 of the air guide plate 300 is greater than the arc radius of the first arc portion 110, so that the second arc portion 310 can rotate around the first arc portion 110, thereby allowing the second arc portion 310 of the air guide plate 300 to rotate from the receiving cavity 220 through the rotation notch 221 with its center as the rotation center to the front side of the front panel 100, so that the body of the air guide plate 300 can rotate from the closed position closed with the air outlet 230 to the front side of the front panel 100; that is, the present invention achieves a simple structure of the air guide plate 300 while still having a large air guiding range.

[0041] In some embodiments, the first arcuate portion 110 is formed by bending an extension from the bottom end of the front panel 100.

[0042] In some embodiments, the air deflector 300 body can be hovered at any position between the closed position and the front side of the front panel 100.

[0043] In some embodiments, the air guide structure further includes a driving member disposed in the accommodating cavity 220. The driving member has a rotating shaft, the central axis of which coincides with the center of the first arc portion 110. The air guide plate 300 also includes a driving arm 320. The driving arm 320, the second arc portion 310, and the air guide plate 300 body are connected in sequence. The driving arm 320 is connected to the rotating shaft so that the driving arm 320 drives the second arc portion 310 to rotate between a first position and a second position under the drive of the rotating shaft.

[0044] The second arc portion 310 is configured to hover at any position between the first position, the second position, and the first and second positions.

[0045] The driving component is generally a motor, whose central axis of rotation coincides with the center of the first arc portion 110, which is also the center of the second arc portion 310, so that the second arc portion 310 can use its center as the rotation center.

[0046] The drive arm 320 is connected to the side of the second arc portion 310 near the first arc portion 110, and is also connected to the end of the second arc portion 310 away from the body of the air guide plate 300.

[0047] The length of the drive arm 320 is greater than the radius of the first arc portion 110, so that the second arc portion 310 can rotate around the first arc portion 110.

[0048] In some embodiments, the air guide structure further includes a first arc groove 210, which is formed by the portion of the middle frame 200 near the first arc portion 110 and cooperates with the first arc portion 110 to form an accommodating cavity 220. The first arc groove 210, the first arc portion 110, and the second arc portion 310 are arranged with the same center, and the arc radius of the first arc groove 210 is larger than the arc radius of the second arc portion 310.

[0049] It is understandable that forming a first arc groove 210 on the middle frame 200 with an arc radius larger than that of the second arc portion 310 allows the second arc portion 310 to rotate freely in the accommodating cavity 220.

[0050] In some embodiments, the central angle of the first arc groove 210 is greater than the central angle of the second arc portion 310. When the central angle of the first arc groove 210 is greater than the central angle of the second arc portion 310 and the arc radius of the first arc groove 210 is greater than the arc radius of the second arc portion 310, it can be ensured that the second arc portion 310 can be almost completely housed in the receiving cavity 220, so that the air guide plate 300 body and the outlet are closed more tightly.

[0051] In some embodiments, one end of the air guide plate 300 body is connected to the side of the second arc portion 310 away from the first arc portion 110, and the air guide plate 300 body is connected to the end of the second arc portion 310 away from the receiving cavity 220.

[0052] The air guide plate 300 body is connected to the end of the second arc portion 310 away from the accommodating cavity 220, so that when the air guide plate 300 body rotates with the second arc portion 310, it can rotate to the maximum angle that the air guide plate 300 body can open under this structure.

[0053] The air guide plate 300 body is generally connected to the outer arc surface of the second arc portion 310 in an approximately perpendicular manner to ensure that the air guide plate 300 body can be opened to the maximum angle.

[0054] In some embodiments, the interior of the air guide plate 300 body has a cavity.

[0055] The air guide plate 300 body has a cavity, which allows the air guide plate 300 body to have a certain thickness, and at the same thickness, it can be lighter than the air guide plate 300 without a cavity, thus reducing the burden on the drive components.

[0056] In some embodiments, the air guide plate 300 body includes a first air guide plate 331 and a second air guide plate 332 that are interlocked with each other, and the first air guide plate 331 and the second air guide plate 332 are spaced apart in at least a portion of their areas to form a cavity.

[0057] The first air guide plate 331 is provided with a first fastening part, and the second air guide plate 332 is provided with a second fastening part that fastens with the first fastening part. The first fastening part and the second fastening part are fastened together to make the first air guide plate 331 and the second air guide plate 332 fastened together.

[0058] Generally, the first fastening part and the second fastening part are respectively located in the middle of the first air guide 331 and the middle of the second air guide 332.

[0059] In some embodiments, the first air guide 331 is connected to the second arc portion 310, and the second air guide 332 is disposed on the side of the first air guide 331 near the middle frame 200.

[0060] The first air guide 331 is integrally formed with the second arc portion 310, and the second air guide 332 is detachably connected to the first air guide 331.

[0061] Specifically, the first air guide 331 and the second arc portion 310 are integrally formed. One end of the second air guide 332 abuts against one end of the first air guide 331, and the other end of the second air guide 332 abuts against the second arc portion 310, so that the second air guide 332 is snapped into the integral structure of the first air guide 331 and the second arc portion 310. At the same time, the second fastening part and the first fastening part on the second air guide 332 and the first air guide 331 are fastened and connected.

[0062] In some embodiments, the side of the air guide plate 300 body near the middle frame 200 is an arc surface that is recessed away from the middle frame 200.

[0063] When the side of the air guide plate 300 near the middle frame 200 is curved, the airflow can be guided and delivered by utilizing the wall adhesion effect under the action of the fluid Coanda effect.

[0064] In some embodiments, the middle frame 200 has an air duct 240 communicating with the outlet. When the air conditioner is in cooling mode, the air guide plate 300 body can be rotated to the front side of the front panel 100, and the air guide plate 300 body is approximately vertical to the front panel 100 and higher than the upper wall of the air duct 240. When the air conditioner is in heating mode, the air guide plate 300 can be rotated to be located between the upper wall and the lower wall of the air duct 240, so that the air outlet direction is downward.

[0065] In some embodiments, an indoor unit is also provided, which includes the aforementioned air guiding structure. Since the air conditioner includes at least some or all of the embodiments of the aforementioned air guiding structure, the indoor unit has at least the beneficial effects of some or all of the aforementioned embodiments, which will not be elaborated further here.

[0066] In some embodiments, an air conditioner is also provided, the refrigeration device including the above-described indoor unit. Since the air conditioner includes at least some or all of the embodiments of the above-described indoor unit, the air conditioner has at least the beneficial effects of some or all of the above-described embodiments, which will not be described in detail here.

[0067] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
