[0036] The realization, functional features, and advantages of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Detailed Embodiment

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0038] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, if there are descriptions such as "first" and "second" in the embodiments of the present utility model, the descriptions of "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes Solution A, Solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0040] In the prior art, additional components for decoration, shaping, connection, etc. are usually provided at the connection between the front panel and the front frame of an air conditioner indoor unit. Generally speaking, the connection between the front panel and the front frame is located at the corners and sides of the casing. At this time, setting the additional components can not only form a better appearance effect, but also simplify the molding difficulty of the front frame and the front panel from a technological perspective. However, due to the complex structure of the casing at these positions, the connection structure of the existing additional components on the casing becomes complicated, resulting in more assembly steps and requirements for the additional components. For example, they need to be placed at a predetermined position first and then connected, and the connection is operated in multiple layers to ensure the assembly stability, thus having an adverse impact on the assembly of the casing, that is, the production efficiency of the air conditioner.

[0041] The present utility model provides an indoor casing.

[0042] Please refer to Figures 2 to 5 , in an embodiment of the present utility model, the indoor casing includes:

[0043] A front frame 100, including a front frame body 110 and an additional component 200. Inside the end wall 111 of the front frame body 110, there is a clamping wall 112. The end wall 111 and the clamping wall 112 enclose a slot 113. The opening of the slot 113 faces forward. The front frame body 110 further has a first clamping portion 114, and the additional component 200 has a second clamping portion 221. The additional component 200 is inserted into the slot 113, and the first clamping portion 114 is clamped with the second clamping portion 221; and

[0044] A front panel 300, which covers the front frame 100.

[0045] The technical solution of the present utility model forms a clamping wall 112 inside the end wall 111 of the front frame body 110. The clamping wall 112 and the end wall 111 enclose a slot 113. The opening of the slot 113 faces the front panel 300. A first clamping portion 114 is provided on the component enclosing the slot 113. Correspondingly, a second clamping portion 221 is provided on the additional component 200. In the direction from the slot opening to the slot bottom of the slot 113, the additional component 200 is inserted into the slot 113 so that the first clamping portion 114 is clamped with the second clamping portion 221, and the additional component 200 can be stably installed on the front frame body 110. Then, the front panel 300 is covered on the front parts of the front frame body 110 and the additional component 200, which not only retains the shaping function of the additional component 200 for the indoor casing, but also ensures the integrity and stability of the indoor casing. In this way, the placement process of the additional component 200 is also the connection process between the additional component 200 and the front frame body 110. The additional component 200 can be stably installed on the front frame body 110 through one installation operation, reducing the installation difficulty and error probability of the additional component 200, thereby improving the assembly efficiency of the indoor casing and the production efficiency of the air conditioner.

[0046] Among them, the first clamping portion 114 can be arranged on the clamping wall 112 or the end wall 111, or on the side wall where the front frame body 110 is connected to the end wall 111. That is, the first clamping portion 114 can be inside the slot 113 or outside the slot 113. The clamping wall 112 can be closer to the panel 300 than the end wall 111, or farther from the panel 300 than the end wall 111. Similarly, the clamping wall 112 can extend obliquely forward from the inner side of the end wall 111 towards the panel 300, making the clamping wall 112 and the end wall 111 inclined relative to each other. Or, the clamping wall 112 and the end wall 111 are arranged in parallel. In this embodiment, the clamping wall 112 is perpendicular to the panel 300, and the end wall 111 is inclined outward relative to the clamping wall 112. The slot 113 is configured as a groove with a V-shaped cross-section and forms a convex shape on this side, enhancing the appearance effect of the indoor casing. In addition, the accessory 200 can be partially exposed outside the structure formed by the panel 300 covering the front frame 100 to achieve a direct appearance effect. Or, after the panel 300 covers the front frame 100, the accessory 200 is inside the indoor casing to achieve a good shape on the outside. It can be understood that the side of the panel 300 can be connected to the end wall 111 through the accessory 200 or directly connected to the end wall 111.

[0047] It should be noted that in the embodiments of the present invention, there are directional indications, such as front and back, etc., which are used to explain the relative position relationship and movement conditions between components in the installation posture of the indoor casing, such as Figure 1 and Figure 2 shown. When the placement posture of the indoor casing changes, the directional indication also changes accordingly.

[0048] In one embodiment, please refer to Figure 1 and Figure 2 , the panel 300 is provided with a connecting flange 310 corresponding to the end wall 111. The connecting flange 310 is bent towards the front frame body 110 and connected to the end wall 111 to cover at least part of the accessory 200. The accessory 200 can be partially received in the space enclosed by the panel 300 and the front frame 100, or partially exposed outside the panel 300 to ensure the decorative effect of the accessory 200. Among them, the connecting flange 310 is connected to the end wall 111 to form a seal for the slot 113, which can not only protect the components of the indoor casing, but also have a limiting effect on the accessory 200 in the slot 113 to enhance the integrity of the indoor casing.

[0049] In one embodiment, please refer to Figure 2 、 Figure 5 and Figure 7, on the side of the clamping wall 112 facing away from the end wall 111, a first clamping portion 114 is provided. The accessory 200 includes a body portion 210 and a clamping flange 220. The body portion 210 is inserted into the slot 113. A second clamping portion 221 is provided on the clamping flange 220 and is spaced opposite to the body portion 210. The clamping wall 112 is clamped between the second clamping portion 221 and the body portion 210. It can be understood that the clamping flange 220 forms an angle relative to the body portion 210 and extends from the inside of the slot 113 across the slot opening to the outside of the slot 113. The second clamping portion 221 is provided on the clamping flange 220 and is spaced opposite to the body portion 210, forming a U-shaped structure. A first clamping portion 114 is provided on the side of the clamping wall 112 facing away from the body portion 210. After the clamping wall 112 is inserted into the U-shaped structure, the first clamping portion 114 is clamped to the corresponding second clamping wall 112. In this way, the clamping position of the accessory 200 and the front panel body 110 is closer to the inside of the housing compared to the slot 113, avoiding occupying the installation space of the accessory 200 due to the setting of the clamping structure, thereby reducing the length of the outdoor housing. Moreover, the U-shaped structure enclosed by the second clamping portion 221, the clamping flange 220, and the body portion 210 also provides a positioning reference for the clamping step of the accessory 200, improving the installation convenience of the accessory 200. Of course, in other embodiments, the first clamping portion 114 can also be provided on the side wall of the slot 113, and the second clamping portion 221 is correspondingly clamped to the first clamping portion 114 within the slot 113.

[0050] Further, in this embodiment, please refer to Figure 3 , Figures 5 to 8 , the second clamping portion 221 is configured as a buckle 222. The buckle 222 is provided with a buckle opening 223. The first clamping portion 114 is configured as a clamping protrusion 115. The clamping protrusion 115 is clamped in the buckle opening 223. Without loss of generality, the second clamping portion 221 has a certain elastic deformation ability. The buckle opening 223 is formed in the middle of the buckle 222. During the installation process of the accessory 200, the clamping protrusion 115 first abuts against the buckle 222 to cause it to deform to a certain extent. After the clamping protrusion 115 is opposite to the buckle opening 223, the buckle 222 elastically resets, so that the clamping protrusion 115 is clamped in the buckle opening 223, and the rear part of the clamping protrusion 115 abuts against the side wall of the buckle opening 223, thereby realizing the clamping of the first clamping portion 114 and the second clamping portion 221, ensuring the stability of the accessory 200 in the slot 113. Of course, in other embodiments, the second clamping portion 221 can also be configured as a protrusion, and a clamping groove is configured on the side of the clamping portion facing away from the slot 113. The protrusion on the clamping flange 220 is clamped in the corresponding clamping groove to realize the clamping of the first clamping portion 114 and the second clamping portion 221.

[0051] Further, in this embodiment, please continue to refer to Figures 5 to 8, on one side of the buckle 222 facing the body portion 210, a first guiding inclined surface 224 is formed. The first guiding inclined surface 224 faces backward and extends obliquely in a direction away from the body portion 210. It can be understood that the first guiding inclined surface 224 is provided to make the opening width of the U-shaped structure formed by the buckle 222, the latching flange 220 and the body portion 210 larger than the width of its bottom, so as to facilitate guiding the latching wall 112 to be inserted into the U-shaped structure, thereby facilitating the latching of the first latching portion 114 and the second latching portion 221. Similarly, in this embodiment, the convex 115 is provided with a second guiding inclined surface 116. The second guiding inclined surface 116 faces forward and extends obliquely in a direction away from the buckle 222. Referring to the setting of the first guiding inclined surface 224, for the position of the first latching portion 114, at the position where the second guiding inclined surface 116 can guide the buckle 222 to deform, so that the convex 115 is latched at the buckle opening 223, thereby facilitating the elastic deformation of the buckle 222, and further improving the convenience of latching between the first latching portion 114 and the second latching portion 221. In an embodiment, only one of the above-mentioned first guiding inclined surface 224 and second guiding inclined surface 116 may be provided, or both may be provided.

[0052] In an embodiment, please refer to Figure 7 and Figure 8 , on one side of the latching wall 112 facing the body portion 210, a limiting rib 117 is provided. The limiting rib 117 extends from the notch of the slot 113 towards the bottom of the slot. One end of the limiting rib 117 is located at the notch of the slot 113, and the other end extends towards the bottom of the slot 113. The limiting rib 117 may extend to the bottom of the slot 113 or may not extend to the bottom of the slot 113. Similarly, the limiting rib 117 may extend in the front-back direction or may extend obliquely in the front-back direction. It should be noted that the body portion 210 is adaptively inserted into the slot 113, and the slot 113 is in the shape of a large opening and a small bottom. During the insertion process of the accessory 200, the second latching portion 221 can be abutted by the limiting rib 117 and then deformed outward of the slot 113 to guide the latching wall 112 to be inserted into the U-shaped mechanism formed by the second latching portion 221, the latching flange 220 and the body portion 210, ensuring that the first latching portion 114 and the second latching portion 221 can be accurately latched and preventing the second latching portion 221 from being inserted into the slot 113 in the same way and causing assembly errors. In addition, the limiting rib 117 also improves the compactness of the body portion 210 in the slot 113 to improve the stability of the accessory 200 installed on the front frame body 110.

[0053] In an embodiment, please refer to Figure 3 and Figure 8, a positioning rib (not shown in the figure) is provided at the bottom of the slot 113. A positioning groove 211 is formed on the side of the accessory 200 facing the bottom of the slot 113, and the positioning rib is clamped in the positioning groove 211. It should be noted that, in the extending direction of the accessory 200, there are blank parts on the opposite sides of the positioning rib. Correspondingly, the positioning groove 211 can be formed by enclosing two convex parts protruding backward from the rear side of the main body part 210, or can be recessed forward from the rear side of the main body part 210. After the accessory 200 is inserted into the slot 113, the positioning rib is adaptively inserted into the positioning groove 211 to limit the accessory 200 in the extending direction of the accessory 200, preventing the accessory 200 from shaking in the slot 113 and improving the installation stability of the accessory 200. Of course, in other embodiments, a groove can also be provided at the bottom of the slot 113, and a convex part protrudes from the rear side of the main body part 210, and the convex part is adaptively inserted into the groove, so as to form a limit in the extending direction of the accessory 200 and ensure the installation stability of the accessory 200.

[0054] In one embodiment, please refer to Figures 9 to 11 , an air outlet 301 is formed on a relative side edge of the front frame body 110 and the panel 300. The accessory 200 has a shaping part 240 provided at the end corresponding to the air outlet 301. The shaping part 240 is exposed outside the panel 300 and wraps around the corner of the clamping wall 112. The shaping part 240 forms a limiting flange 241 on the side facing the air outlet 301, and the limiting flange 241 abuts against the clamping wall 112. It can be understood that the shaping part 240 is exposed at the end of the air outlet 301 to decorate the indoor machine shell and also improve the structural stability of the end of the air outlet 301. In this embodiment, the clamping wall 112 also has a corner at the end corresponding to the air outlet 301. The shaping part 240 wraps around this corner of the clamping wall 112 at the end of the air outlet 301, which can not only provide structural support for the shaping part 240 by the clamping wall 112, but also provide a positioning reference for the installation of the shaping part 240 of the accessory 200 and improve the structural stability of the indoor machine shell. The shaping part 240 is folded on the side facing the air outlet 301 to form a limiting flange 241, and the limiting flange 241 abuts against the side of the clamping wall 112 facing the air outlet 301, so as to use the limiting flange 241 to limit the accessory 200 in the extending direction of the air outlet 301, prevent the accessory 200 from shaking, and improve the structural stability of the indoor machine shell. Of course, the limiting flange 241 also prevents the clamping wall 112 from being exposed outside the air outlet 301 and improves the appearance integrity of the indoor machine shell.

[0055] Furthermore, in this embodiment, please refer to Figure 3 and Figure 12, the second engaging portion 221 is configured as a spring catch 230 provided on the side of the shaping portion 240 close to the bottom of the slot 113, and the first engaging portion 114 is correspondingly configured as a card slot (not shown in the figure), and the spring catch 230 is engaged in the card slot. It should be noted that the rear side of the shaping portion 240 is close to the bottom of the slot 113, and the first engaging portion 114 provided on the engaging wall 112 is closer to the slot opening of the slot 113. Therefore, the second engaging portion 221 configured as the spring catch 230 is provided on the rear side of the shaping portion 240, and the spring catch 230 is engaged with the corresponding card slot. In the front-rear direction, the accessory 200 has at least two engaging relationships with the front panel body 110, thereby improving the connection stability between the accessory 200 and the front panel body 110. Among them, the card slot can be formed on the side wall adjacent to the bottom of the slot 113, or can be formed on the side wall of the front panel body 110 connected to the end wall 111. Of course, in other embodiments, the second engaging portion 221 at the rear of the shaping portion 240 can also be configured as a snap 222, a snap opening 223 is formed on the snap 222, and the corresponding first engaging portion 114 is configured as a snap projection 115 to engage the accessory 200 with the front panel body 110 at the rear of the shaping portion 240.

[0056] In one embodiment, please refer to Figure 3 and Figure 12 , multiple groups of the second engaging portion 221 and the first engaging portion 114 are provided and distributed along the extending direction of the accessory 200. It can be understood that the multiple second engaging portions 221 and the multiple first engaging portions 114 are provided in one-to-one correspondence, so that one second engaging portion 221 and one first engaging portion 114 form a set of engaging structures, and multiple sets of engaging structures are distributed in the extending direction of the accessory 200, thereby improving the stability of the accessory 200 in its extending direction. Combining with the description of the above technical solution, in this embodiment, the cooperation of the multiple second engaging portions 221 and the multiple first engaging portions 114, and the cooperation of the second engaging portion 221 and the first engaging portion 114 on the engaging wall 112 form a limiting effect on the accessory 200 in the extending direction of the accessory 200, the front-rear direction, and the extending direction of the air outlet 301, so that the accessory 200 can be stable in the slot 113. While improving the installation convenience of the accessory 200, the installation stability of the accessory 200 can also be effectively guaranteed.
