In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The following describes a chassis assembly 10 of an air conditioner indoor unit according to an embodiment of the present invention with reference to the accompanying drawings.

[0046] like Figure 3-Figure 6 As shown, a chassis assembly 10 of an air conditioner indoor unit according to an embodiment of the present invention includes a chassis 1 and a screw cover 2 .

[0047] like Figure 3-Figure 6 As shown, the front end of the chassis 1 has a screw groove 11, and the screw groove 11 has a front open opening 12 and a top open opening 13 that are interconnected. The screws 3 used to connect the chassis 1 and the front panel 20 of the air-conditioning indoor unit 100 are suitable for passing through the rear wall of the screw groove 11 from the front open opening 12 to the rear, and the width of the upper end of the front open opening 12 is smaller than the maximum width of the front open opening 12.

[0048] It can be understood that the opening of the front open opening 12 faces forward, and the opening of the top open opening 13 faces upward. The front open opening 12 facilitates the loading and unloading of the screws 3, thereby facilitating the disassembly and maintenance between the chassis 1 and the front panel 20. The top open opening 13 makes it easy to observe the installation status of the screws 3, thereby facilitating the installation and maintenance personnel to load and unload the screws 3.

[0049] Furthermore, if Figure 4 As shown, a mounting groove 14 and a mounting hole 15 are provided on the rear side wall of the screw groove 11, the mounting groove 14 is recessed backward, the mounting hole 15 is penetrated on the bottom wall of the mounting groove 14, and the rear side of the mounting groove 14 has a connecting port 16 opening upward, which is used to connect the front panel 20 of the air-conditioning indoor unit 100, and the bottom of the front panel 20 has a connecting piece, which can be located in the connecting port 16, and the connecting piece has a screw hole matching the screw 3, the screw groove 11 and the connecting port 16 are connected through the mounting hole 15, thereby, the screw 3 can be connected to the bottom connecting piece of the front panel 20 of the air-conditioning indoor unit 100 through the mounting hole 15, so as to realize the connection between the front panel 20 and the chassis 1.

[0050] Furthermore, if Figure 4As shown, the diameter of the head of the screw 3 is larger than the length of the mounting groove 14 in the left-right direction, thereby limiting the head of the screw 3 from entering the mounting groove 14, thereby facilitating the loading and unloading of the screw 3. At the same time, the mounting hole 15 extends in the up-down direction to form a strip hole, which can facilitate the up-and-down adjustment of the position of the screw 3 during installation, thereby facilitating the loading and unloading of the screw 3.

[0051] like Figure 4 and Figure 7 As shown, the screw cover 2 includes a cover body 21, which is arranged at the front opening 12 to cover the screw 3 at the front side. The shape and size of the cover body 21 are the same as those of the front opening 12, that is, the width of the upper end of the cover body 21 is smaller than the maximum width of the cover body 21. The cover body 21 covers the screw 3 at the front side, which can protect the screw 3 from being removed by mistake and reduce the entry of foreign matter to cause the screw 3 to rust. Since the shape and size of the cover body 21 are the same as those of the front opening 12, the screw cover 2 can completely cover the front opening 12, and the sealing performance is good.

[0052] Furthermore, if Figure 4 , Figure 6 and Figure 7 As shown, when the screw cover 2 is installed to the chassis 1, the cover body 21 blocks the front opening 12. At this time, when the air-conditioning indoor unit 100 vibrates during transportation or other situations, the screw cover 2 tends to move upward. Since the width of the upper end of the front opening 12 is smaller than the maximum width of the front opening 12, the width of the upper end of the cover body 21 is smaller than the maximum width of the cover body 21, the screw cover 2 will be restricted from moving upward, thereby preventing the screw cover 2 from moving upward and detaching from the chassis 1, thereby improving the installation stability of the screw cover 2 on the chassis 1.

[0053] In addition, the screw cover 2 is an elastic part such as rubber and has a certain deformation ability. When disassembling the screw cover 2, the user can squeeze the screw cover 2 with force and push it into the screw groove 11, and install the screw cover 2 on the chassis 1 by relying on the deformation and reduction of the screw cover 2. When disassembling, the screw cover 2 can be pushed outward from the top open mouth 13, and the screw cover 2 can be disassembled by relying on the deformation and reduction of the screw cover 2. This makes loading and unloading convenient and improves loading and unloading efficiency.

[0054] According to the chassis assembly 10 of the air-conditioning indoor unit of the embodiment of the present invention, a front opening 12 is set in the screw groove 11, the width of the upper end of the front opening 12 is smaller than the maximum width of the front opening 12, and then a screw cover 2 is set, and the cover body 21 of the screw cover 2 is covered at the front opening 12 and blocks the screw 3 on the front side, and the shape of the cover body 21 is the same as the shape and size of the front opening 12, so as to prevent the screw cover 2 from moving upward and detaching from the chassis 1, thereby improving the installation stability of the screw cover 2 on the chassis 1, and making it difficult for the screw cover 2 to loosen upward.

[0055] In some embodiments of the present invention, Figure 6 As shown, the front opening 12 includes a first opening area 121 and a second opening area 122. The first opening area 121 is located below the second opening area 122. In the direction from bottom to top, the width of the first opening area 121 gradually increases, and the width of the second opening area 122 gradually decreases.

[0056] It is understandable that if Figure 7 As shown, the cover body 21 includes a first section 211 and a second section 212. The first section 211 is located below the second section 212. In the direction from bottom to top, the width of the first section 211 gradually increases, and the width of the second section 212 gradually decreases. The cover body 21 is arranged at the front opening 12. When the cover body 21 wants to move upward, the width of the upper end of the second open area 122 is smaller than the maximum width of the first section 211 and the second section 212, thereby limiting the cover body 21 from moving upward and detaching from the chassis 1, thereby improving the installation stability of the screw cover 2 on the chassis 1 and making it difficult for the screw cover 2 to loosen.

[0057] In addition, if Figure 6 and Figure 7 As shown, the side edge of the first open area 121 is in an arc shape, and the side edge of the first open area 121 protrudes downward. The side edge of the first section 211 is in an arc shape, and the side edge of the first section 211 also protrudes downward. Therefore, in the bottom-up direction, the width of the first open area 121 gradually increases, and the width of the first section 211 gradually increases. At the same time, the arc shape makes the side edges of the first open area 121 and the side edges of the first section 211 smoother, which is convenient for installation and improves installation efficiency.

[0058] The side edge of the second open area 122 is straight, and the ends of the side edges on both sides of the second open area 122 away from the first open area 121 are inclined toward each other. The side edge of the second section 212 is straight, and the ends of the side edges on both sides of the second section 212 away from the first section 211 are inclined toward each other. Therefore, in the bottom-up direction, the width of the second section 212 gradually decreases, and the width of the second open area 122 gradually decreases. At the same time, the straight line makes the structure simple.

[0059] In some embodiments of the present invention, Figure 4 and Figure 7 As shown, the screw cover 2 further includes a flange 22, which is arranged on the outer peripheral wall of the cover body 21 and located at the front end of the cover body 21, and the rear side of the flange 22 abuts against the front surface of the chassis 1. Thus, the flange 22 can limit the screw cover 2 from moving backward, thereby further improving the installation stability of the screw cover 2 on the chassis 1, so that the screw cover 2 is not easy to loosen.

[0060] In some embodiments of the present invention, Figure 4 and Figure 7 As shown, the flange 22 extends from one end in the middle width direction of the upper end of the cover body 21 along the circumferential direction of the cover body 21 to the other end in the middle width direction of the upper end of the cover body 21. As a result, the area of ​​the flange 22 is increased, thereby improving the reliability of the flange 22 in limiting the backward movement of the screw cover 2, thereby further improving the installation stability of the screw cover 2 on the chassis 1, making it difficult for the screw cover 2 to loosen. In addition, the reliability of the screw cover 2 covering the front open mouth 12 is also improved, thereby improving the protection of the screw 3 and preventing the screw 3 from rusting or falling off due to external factors.

[0061] In some embodiments of the present invention, Figure 4 and Figure 7 As shown, the front side of the flange 22 is tilted backward in the direction from the end of the flange 22 connected to the cover body 21 to the end of the flange 22 away from the cover body 21. As a result, the rear side of the flange 22 can better stop against the front surface of the chassis 1, and the probability of the flange 22 tilting forward can be reduced, thereby better limiting the backward movement of the screw cover 2, thereby further improving the installation stability of the screw cover 2 on the chassis 1, making it difficult for the screw cover 2 to loosen.

[0062] At the same time, the flange 22 makes it easier for the user to grab the screw cover 2 and press to install, making disassembly convenient and improving disassembly efficiency. When installing the screw cover 2, the user can pinch the flange 22 and squeeze it hard, so that the screw cover 2 is deformed and reduced, and pushed into the screw groove 11, thereby sealing the front opening 12. When disassembling, the flange 22 can be lifted and the screw cover 2 can be pushed outward from the top opening 13, and the screw cover 2 can be disassembled by relying on the deformation and reduction of the screw cover 2.

[0063] In some embodiments of the present invention, Figure 4 and Figure 7 As shown, the screw cover 2 also includes a buckle 23, which is arranged on the outer peripheral wall of the cover body 21 and is located at the rear end of the cover body 21. The front side of the buckle 23 abuts against the front side wall forming the screw groove 11. Thus, the buckle 23 can limit the forward movement of the screw cover 2, thereby further improving the installation stability of the screw cover 2 on the chassis 1, making it difficult for the screw cover 2 to loosen.

[0064] Furthermore, if Figure 4 and Figure 7As shown, the buckle 23 is arranged on the outer peripheral wall of the cover body 21 and is located at the rear end of the cover body 21, and the flange 22 is arranged on the outer peripheral wall of the cover body 21 and is located at the front end of the cover body 21, so that a slot 25 is formed between the buckle 23 and the flange 22, and the part of the chassis 1 forming the front side wall of the screw groove 11 can be stuck in the slot 25, thereby limiting the forward and backward movement of the screw cover 2, wherein the flange 22 can limit the screw cover 2 to move backward, and the buckle 23 can limit the screw cover 2 to move forward, and in addition, the shape of the cover body 21 is the same as the shape and size of the front side opening 12, which can limit the screw cover 2 to move in the left and right direction. As a result, the movement of the screw cover 2 on the horizontal plane perpendicular to the up and down direction is limited, thereby further improving the installation stability of the screw cover 2 on the chassis 1, so that the screw cover 2 is not easy to loosen.

[0065] In addition, if Figure 4 and Figure 7 As shown, in the direction from the end where the buckle 23 is connected to the cover body 21 to the end of the buckle 23 away from the cover body 21, the rear side surface of the buckle 23 is inclined forward, thereby, the front side surface of the buckle 23 can better stop against the front side wall forming the screw groove 11, and the buckle 23 is not easy to warp up, thereby further improving the installation stability of the screw cover 2 on the chassis 1, making the screw cover 2 not easy to loosen.

[0066] In some embodiments of the present invention, Figure 7-Figure 9 As shown, the buckles 23 are multiple and spaced apart along the circumferential direction of the cover body 21, thereby improving the connection reliability and stability between the screw cover 2 and the chassis 1. Fig. 9 In the example shown, there are three buckles 23, which are respectively located at the left and right ends and the lower end of the cover body 21, but the present invention is not limited to this. The number of buckles 23 can be more, such as 4, 5, 6 or 7.

[0067] In some embodiments of the present invention, Figure 4 As shown, the upper end surface of the buckle 23 is flush with the upper end surface of the chassis 1, and the upper end surface of the chassis 1 is provided with a limiting rib (not shown) extending backward, and the lower end surface of the limiting rib abuts against the upper end surface of the buckle 23. It can be understood that the limiting rib extends backward, so that when the screw cover 2 is installed on the chassis 1, there is no obstruction at the front end of the chassis 1, which facilitates the installation of the screw cover 2 and the chassis 1. The lower end surface of the limiting rib abuts against the upper end surface of the buckle 23, which can further limit the upward movement of the screw cover 2, thereby further improving the installation stability of the screw cover 2 on the chassis 1, so that the screw cover 2 is not easy to loosen.

[0068] In some embodiments of the present invention, Figure 7As shown, the thickness H of the cover body 21 is 5-6 mm, such as 5 mm, 5.2 mm, 5.4 mm or 6 mm, etc. It is understandable that if the thickness of the cover body 21 is less than 5 mm, the strength of the cover body 21 will be insufficient, thereby reducing the installation stability of the cover body 21 and the chassis 1, and it is easy to loosen. If the thickness of the cover body 21 is greater than 6 mm, the depth of the screw groove 11 in the front-to-back direction will be too large, so that the rear side wall of the screw groove 11 is set too backward, which is not conducive to the installation of the screw 3.

[0069] Therefore, the thickness of the cover body 21 is 5-6 mm, which can ensure the strength of the cover body 21, improve the installation stability of the cover body 21 and the chassis 1, make the screw cover 2 not easy to loosen from the chassis 1, and also facilitate the installation of the screws 3 and improve the assembly efficiency.

[0070] In some embodiments of the present invention, Fig.10 and Fig.11 As shown, in the front-to-back direction, the cover body 21 is spaced apart from the screw 3. It can be understood that, since the thickness of the cover body 21 is 5-6 mm, the thickness of the cover body 21 is small, so that there is enough gap between the rear side walls of the screw slot 11, so that the cover body 21 is spaced apart from the screw 3, thereby, the rear side wall of the screw slot 11 can have a certain space to be set forward, so as to facilitate the installation of the screw 3 and improve the assembly efficiency. At the same time, the spacing of the cover body 21 and the screw 3 can prevent the screw 3 from contacting the rear side of the cover body 21, so as to avoid the installation interference of the screw 3 and the screw cover 2.

[0071] In some embodiments of the present invention, Figure 4 and Figure 7 As shown, the rear side of the cover body 21 has an escape groove 24 for escaping the head of the screw 3, and the escape groove 24 is arranged opposite to the screw 3 in the front-to-back direction. It can be understood that the escape groove 24 is recessed from the rear side of the cover body 21 to the front side, and the length of the escape groove 24 in the left-right direction is greater than the diameter of the screw 3, so that when the screw 3 is too long, the head of the screw 3 can be located in the escape groove 24, thereby preventing the screw 3 from contacting the rear side of the cover body 21, thereby avoiding the installation interference of the screw 3 and the screw cover 2.

[0072] In addition, part of the screw 3 can extend into the avoidance groove 24. When the screw cover 2 is to move upward, the lower side wall of the avoidance groove 24 will contact the head of the screw 3 (when the head of the screw 3 is located in the avoidance groove 24), thereby limiting the upward movement of the screw cover 2, further improving the installation stability of the screw cover 2 on the chassis 1, and preventing it from getting loose.

[0073] In some embodiments of the present invention, Figure 4As shown, the upper end of the cover body 21 is flush with the upper surface of the chassis 1, thereby making the structure of the screw cover 2 simple and facilitating the installation of the screw cover 2 and the chassis 1, thereby improving production efficiency and installation efficiency.

[0074] In some embodiments of the present invention, the upper end surface of the cover body 21 is provided with a stopper (not shown in the figure) extending upward. It is understandable that, after the chassis assembly 10 and the front panel 20 are installed, there is a certain gap between the upper end surface of the cover body 21 and the lower end surface of the front panel 20. When the air conditioner indoor unit 100 encounters bumps, the screw cover 2 moves upward with the bumps and is easy to fall out of the gap. The upper end surface of the cover body 21 is provided with a stopper extending upward, which can reduce the gap between the upper end surface of the screw cover 2 and the lower end surface of the front panel 20, reduce the distance that the screw cover 2 moves upward, thereby reducing the probability of the screw cover 2 falling, and further improves the installation stability of the screw cover 2 on the chassis 1, and is not easy to loosen.

[0075] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, there are multiple screw slots 11 spaced apart along the left-right direction of the chassis 1, and there are multiple screw covers 2 corresponding to the multiple screw slots 11. It can be understood that one screw 3 can be installed in each screw slot 11, and multiple screw slots 11 can be installed with corresponding multiple screws 3, thereby, the front panel 20 of the air conditioner indoor unit 100 and the chassis assembly 10 can be connected by multiple screws 3, which improves the connection reliability, and the multiple screw covers 2 are arranged in a one-to-one correspondence with the multiple screw slots 11, so that the multiple screws 3 can be protected, and at the same time, the screw cover 2 has high stability on the chassis 1 and is not easy to loosen.

[0076] For example, Figure 3 and Figure 5 In the example shown, there are two screw slots 11 and two screw covers 2, but the present invention is not limited to this. There can be more screw slots 11 and there can be correspondingly more screw covers 2, such as 3, 4, 5 or 6.

[0077] The air conditioner indoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0078] like Figure 1 and Figure 2 As shown, the air conditioner indoor unit 100 according to the embodiment of the present invention includes the above-mentioned chassis assembly 10.

[0079] Specifically, refer to Figure 1 and Figure 2The air conditioner indoor unit 100 further includes a front panel 20, a duct member 40, an electric control box 30, a top cover assembly 50, an evaporator assembly 70 and a rear box assembly 60.
