DETAILED DESCRIPTION

[0036] In the description of the present invention, it should be noted that the terms "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] When existing cabinet air conditioner indoor units are discharging air, the cooling energy is not concentrated toward the front, and the cold air often escapes from the rear. For cabinet air conditioners, this cold air encounters the hotter wall surface when exiting from the rear, which can easily cause mold on the wall and waste cooling energy. The present invention prevents cold air from escaping from the rear of the air conditioner by providing a windshield. Furthermore, the transparent windshield increases the brightness of the air outlet, making it more aesthetically pleasing and reducing the visual effect, so that the structure does not appear overly bulky when viewed. In other words, the transparent windshield prevents cold air from escaping from the rear of the air conditioner without sacrificing the air conditioner's aesthetics.

[0039] To further illustrate the technical solution of the present invention, Figures 1-6 As shown, the following specific embodiments are provided.

[0040] Example 1

[0041] In an embodiment of the present invention, a Figure 1 and Figure 2 The cabinet-type air-conditioning indoor unit shown includes a casing and an air outlet mechanism disposed in the casing;

[0042] The housing includes a front housing 1 and a rear housing 2. A first air outlet 11 is formed on the surface of the front housing 1, and a first opening 21 is formed on the surface of the rear housing 2. The first air outlet 11 and the first opening 21 are arranged opposite to each other.

[0043] The air outlet mechanism includes an air outlet housing 3, which is surrounded by an air outlet duct 31. The air outlet duct 31 includes a second air outlet 311 and a second opening 312 which are arranged opposite to each other.

[0044] The second air outlet 311 is arranged corresponding to the first air outlet 11 and is connected to the first air outlet 11, the second opening 312 is arranged corresponding to the first opening 21 and a windshield 4 made of transparent material is arranged at the second opening 312, and the windshield 4 is used to prevent the wind in the air outlet duct 31 from flowing out from the second opening 312.

[0045] In the embodiment of the present invention, a windshield 4 is provided at the second opening 312 of the air outlet shell 3 (i.e., the opening toward the side of the rear casing 2), so as to prevent cold air from flowing out from the rear side of the air conditioner. At the same time, since the windshield 4 is made of transparent material, the aesthetics of the air conditioner will not be lost.

[0046] like Figure 2 As shown, in order to facilitate the installation of the windshield 4, a mounting assembly 41 is provided on the windshield 4 in this embodiment.

[0047] Further, such as Figure 2 As shown, there are two groups of mounting components 41 on the windshield 4, one group is connected to the air outlet housing 3, and the other group is connected to the rear casing 2 to connect the air outlet housing 3, the windshield 4 and the rear casing 2 together.

[0048] In this embodiment, when the wind shield 4 is assembled, the air outlet housing 3 and the rear housing 2 are connected together in a one-to-two manner, thereby improving the strength of the air outlet housing 3 and the rear housing 2.

[0049] Furthermore, the windshield 4 has a first sealing surface proximal to the rear housing 2 and a second sealing surface proximal to the air outlet housing 3. When the windshield 4 is installed between the rear housing 2 and the air outlet housing 3 via the mounting assembly 41, the first sealing surface abuts against the rear housing 2 to seal the first opening 21, and the second sealing surface abuts against the air outlet housing 3 to seal the second opening 312. This tightly connects the air outlet housing 3 and the rear housing 2, further enhancing the strength of both components.

[0050] In any of the above embodiments, Figure 5 As shown, the installation component 41 includes a pin 411 and a screw 412 arranged along the edge of the wind shield 4, that is, the wind shield 4 is fixed to the air outlet shell 3 and the rear casing 2 by a combination of the pin 411 and the screw 412. During installation, the wind shield 4 is assembled on the air outlet shell 3 and the rear casing 2 through the pin 411, and is fixed through the screw 412 hole, so that the wind shield 4 is not easy to loosen or deform.

[0051] The advantage of using the latch 411 and screw 412 in the mounting assembly 41 of this embodiment is that the latch 411 can be positioned during installation, while the screw 412 can effectively secure the positioned windshield 4, thereby forming a more stable structure between the installed windshield 4, the air outlet housing 3, and the rear housing 2. Furthermore, since the provision of the latch 411 facilitates positioning, the assembly of the windshield 4 is faster, thereby improving assembly efficiency. Furthermore, since the latch 411 is harder than the air outlet housing 3 and the rear housing 2, when the latch 411 is inserted into the air outlet housing 3 and the rear housing 2, it can also increase the hardness of the air outlet housing 3 and the rear housing 2.

[0052] It is worth noting that the above-mentioned "pin 411 and screw 412 are arranged along the edge of the wind shield 4" are arranged on both sides of the wind shield 4, that is, the wind shield 4 is provided with a pin 411 and a screw 412 on both sides.

[0053] Specifically, the above-mentioned pins 411 and screws 412 are provided in plurality, and the plurality of pins 411 and the plurality of screws 412 are evenly distributed on the edge of the wind shield 4, and the plurality of pins 411 and the plurality of screws 412 are staggered. By staggering the plurality of pins 411 and the plurality of screws 412 on the wind shield 4, the overall strength of the wind shield 4, the air outlet housing 3 and the rear housing 2 after installation can be improved.

[0054] More specifically, the axes of the pins 411 on either side of the windshield 4 do not overlap, and the axes of the screws 412 on either side of the windshield 4 do not overlap, and the pins 411 and screws 412 on either side of the windshield 4 do not overlap. This arrangement allows the windshield 4 to achieve the best connection (i.e., the pins 411 and screws 412 on either side of the windshield 4 are distributed along the entire circumference of the windshield 4 after projection) with minimal cost (i.e., a smaller number of pins 411 and screws 412 are provided). This results in a higher overall strength of the connected windshield 4, air outlet housing 3, and rear housing 2.

[0055] In any of the above embodiments, Figure 6 As shown, to further facilitate positioning of the windshield 4 during installation, in this embodiment, a long pin is provided among the multiple pins 411 located on each side of the windshield 4. When installing the windshield 4, the long pin can be positioned by simply inserting it into a slot provided on the air outlet housing 3 or the rear housing 2, thereby further improving assembly efficiency.

[0056] In any of the above embodiments, Figure 5 and Figure 6 As shown, the windshield 4 is a curved panel with its concave surface facing the rear housing 2;

[0057] The windshield 4 has a top end disposed close to the air outlet housing 3 and a bottom end disposed close to the rear housing 2, and the windshield 4 extends obliquely from the top end toward the bottom end.

[0058] Among them, the long pins located on both sides of the wind shield 4 are respectively arranged at the middle of the top end of the wind shield 4 and the middle of the bottom end of the wind shield 4, and the long pin located at the middle of the top end of the wind shield 4 is arranged toward the air outlet housing 3, and the long pin located at the middle of the bottom end of the wind shield 4 is arranged toward the rear housing 2.

[0059] By setting the baffle 4 as an arc-shaped plate, on the one hand, the wind shield 4 can be more closely matched with the air outlet shell 3 and the rear casing 2 during assembly. On the other hand, when the air conditioner is outputting air, the airflow blowing toward the rear side of the air conditioner can be guided to the front side through its arc curve, thereby reducing wind noise.

[0060] It is worth noting that if Figure 3 and Figure 4 As shown, conventional air conditioner casings and air duct components are usually made of injection molded parts, so their strength is relatively weak. Therefore, in order to prevent the air outlet housing 3 and the rear housing 2 (i.e., the upper air outlet) from deformation during the handling and transportation of the air conditioner, in this embodiment, the density of the windshield 4 is set to be greater than the density of the rear housing 2 and the air outlet housing 3, that is, the windshield 4 is made of a dense transparent material. In this way, when the air conditioner is transported and carried, the upper air outlet is subjected to stress, and the air outlet housing 3 and the rear housing 2, which have weaker structural strength, will transfer the force to the windshield 4. The windshield 4 is made of a dense transparent material, and the surface can effectively absorb stress, thereby eliminating the stress concentration in the upper half, thereby ensuring the reliability of the structural strength at the upper air outlet.

[0061] In any of the above embodiments, Figure 1 As shown, an air inlet is further provided at the bottom of the air outlet housing 3, and an air guide plate 5 is rotatably provided at the air inlet;

[0062] It is worth noting that for an air conditioner with the air outlet set at the top, due to the limitation of the air outlet angle, only oblique upward air guidance can be achieved. However, in the embodiment of the present invention, since a curved air guide plate 5 is provided, when the air guide plate 5 is rotated to face the side of the rear casing 2, the air can first come into contact with the air guide plate 5, and then be discharged from the first air outlet 11 along the horizontal direction of the first air outlet 11 through the guidance of the curved wind shield plate 4, thereby achieving a multi-angle air supply effect of the air conditioner.

[0063] Optionally, the air guide plates 5 include multiple air guide plates 5, and the multiple air guide plates 5 are sequentially arranged at the air inlet end of the air outlet housing 3 along the thickness direction of the housing, and the multiple air guide plates 5 can be rotated independently or synchronously.

[0064] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
