[0045] Combined Figures 1 to 14 As shown, the embodiments of the present disclosure provide a housing for an air conditioner indoor unit. The housing for the air conditioner indoor unit includes a chassis 10 and a shroud 20. The chassis 10 includes a chassis body 101 and a first flange 102. The first flange 102 is provided at the outer edge of the chassis body 101 and extends upward; the shroud 20 is provided along the circumference of the chassis 10 and extends along the circumferential direction of the chassis 10, as Figure 1As shown, the enclosure 20 is connected to the chassis 10 to enclose an installation space 30; wherein, a latching protrusion 201 is provided on the side of the enclosure 20 facing the first folded edge 102, and the first folded edge 102 is provided with a latching hole 103. When the enclosure 20 is connected to the chassis 10, the enclosure 20 corresponds to the first folded edge 102, and the latching protrusion 201 is latched in the latching hole 103.

[0046] In the disclosed embodiment, the chassis 10 includes a chassis body 101 and a first folded edge 102. The first folded edge 102 is arranged at the outer edge of the chassis body 101 and extends upward, so that the first folded edge 102 can provide space for the connection between the chassis 10 and the enclosure 20, and facilitate the connection between the chassis 10 and the enclosure 20. The enclosure 20 is provided with a clamping protrusion 201 on one side facing the first folded edge 102, and the first folded edge 102 is provided with a clamping hole 103. When the enclosure 20 and the chassis 10 need to be connected, the clamping protrusion 201 is inserted into the clamping hole 103, so that the enclosure 20 and the chassis 10 can be limited and connected, and the enclosure 20 and the chassis 10 will not be separated, and then the enclosure 20 and the chassis can be further connected and reinforced, so that there is no need to manually hold the enclosure 20, and one person can complete the connection between the enclosure 20 and the chassis, thereby improving production efficiency and saving manpower and cost.

[0047] Optionally, when the latch protrusion is inserted into the latch hole, the lower wall surface of the latch protrusion abuts against the lower wall surface of the latch hole, which can limit the downward movement of the enclosure relative to the chassis.

[0048] Optionally, when the enclosure 20 is connected to the chassis 10, the enclosure 20 is in contact with (fitted with or close to) the first folded edge 102, so as to facilitate the engagement of the protrusions and holes of the enclosure and the first folded edge.

[0049] Alternatively, if Figure 4 and Figure 10 As shown, the enclosure 20 abuts against the side of the first fold 102 facing away from the installation space 30 .

[0050] In the disclosed embodiment, the enclosure 20 is in contact with or close to the side of the first folded edge 102 that is away from the installation space 30, that is, the outer side of the first folded edge 102. In this way, when installing the enclosure 20, the enclosure 20 can be pushed inward so that the protrusion 201 of the enclosure 20 can be inserted into the hole 103, which facilitates the operation and movement of the enclosure 20.

[0051] Alternatively, if Figure 7 , Figure 8 , Figure 12 and Figure 13As shown, the card projection 201 includes a connecting portion 202 and a guiding portion 203. The connecting portion 202 is connected to the surrounding plate 20. The guiding portion 203 is connected to one end of the connecting portion 202 facing away from the surrounding plate 20. Wherein, guiding surfaces 204 are formed on both sides of the guiding portion 203, and the distance between the guiding surfaces 204 on both sides of the guiding portion 203 gradually decreases along the direction in which the card projection 201 is inserted into the card hole 103.

[0052] In the embodiment of the present disclosure, the connecting portion 202 of the card projection 201 is used to connect with the surrounding plate 20. The guiding portion 203 can guide the card projection 201 to be inserted into the card hole 103. The guiding surfaces 204 on both sides of the guiding portion 203 are inclined, and the distance between the guiding surfaces 204 on both sides gradually decreases. In this way, the cross-sectional area of the end of the guiding portion 203 is relatively small, and it can be easily inserted into the card hole 103, and then the card projection 201 can be smoothly inserted into the card hole 103.

[0053] Optionally, as Figures 12 to 14 shown, the card projection 201 is further provided with a limiting portion, and the card hole 103 is provided with a limiting and mating portion. When the surrounding plate 20 is connected to the chassis, the limiting portion cooperates with the limiting and mating portion to limit the card projection 201 from disengaging from the card hole 103.

[0054] In the embodiment of the present disclosure, after the card projection 201 is inserted into the card hole 103, the limiting portion and the limiting and mating portion can cooperate to limit, restricting the card projection 201 from disengaging from the card hole 103. In this way, it can prevent the surrounding plate 20 from falling off, and further improve the connection stability between the surrounding plate 20 and the chassis.

[0055] Optionally, a limiting notch 206 is formed by the side wall portion of the card projection 201 recessing towards the center of the card projection 201. The hole wall of the card hole 103 is inclined towards the center of the card hole 103 in the up-down direction to form a limiting protrusion 106. When the limiting portion cooperates with the limiting and mating portion, the limiting notch 206 is engaged with the limiting protrusion 106. Here, the center of the card projection 201 refers to the center in the length direction of the card projection along the horizontal direction, and the center of the card hole 103 refers to the center in the length direction of the card hole 103 along the horizontal direction.

[0056] In the embodiment of the present disclosure, a limiting notch 206 is formed on the side wall of the card projection 201, and a limiting protrusion 106 is formed on the hole wall of the card hole 103. In this way, after the card projection 201 is inserted into the card hole 103, the limiting notch 206 is engaged with the limiting protrusion 106. One side of the limiting notch 206 can be engaged with the side of the limiting protrusion 106 facing the installation space 30. In this way, it can restrict the card projection 201 from moving in the direction away from the installation space 30, and further prevent the surrounding plate 20 from separating from the chassis 10.

[0057] Optionally, one or both side walls of the clamping projection 201 in the left-right direction are provided with limiting notches 206, and the number of the limiting protrusions 106 is the same as that of the limiting notches 206 and they correspond to each other one by one.

[0058] Optionally, the card hole 103 includes an insertion part 104 and a mounting part 105. The length of the insertion part 104 is greater than or equal to the maximum length of the clamping projection 201 so that the clamping projection can be inserted into the insertion part 104. The mounting part 105 is connected below the insertion part 104, and a limiting and cooperating part is configured on the hole wall of the mounting part 105. When the surrounding plate 20 and the chassis 10 are connected, the clamping projection 201 moves from the insertion part 104 to the mounting part 105.

[0059] In the embodiment of the present disclosure, the length of the insertion part 104 is greater than or equal to the maximum length of the clamping projection 201, so that the clamping projection 201 can be smoothly inserted into the insertion part 104. The mounting part 105 is located below the insertion part 104. Thus, when the clamping projection 201 is inserted into the insertion part, the surrounding plate 20 moves downward under the action of gravity, and then drives the clamping projection 201 to move downward into the mounting part 105. A limiting and cooperating part is configured on the hole wall of the mounting part 105, so that the limiting part of the clamping projection 201 can cooperate with the limiting and cooperating part, and the clamping projection 201 can be limited to prevent the clamping projection 201 from detaching from the card hole 103. When it is necessary to disassemble the surrounding plate 20, lift the surrounding plate 20 upward, and the clamping projection 201 moves from the mounting part 105 to the upper insertion part 104. In this way, the limiting part and the current cooperating part do not correspond, and the limitation is released. Then the clamping projection 201 can be pulled out of the card hole 103 from the insertion part 104 without being restricted.

[0060] Optionally, a limiting protrusion 106 is configured on the hole wall of the mounting part 105, and a limiting notch 206 is configured on the side wall of the clamping projection 201. When the clamping projection 201 is located in the mounting part 105, the limiting protrusion 106 is clamped with the limiting notch 206.

[0061] Optionally, as Figures 4 to 9 shown, a first avoidance groove is formed by partial upward depression of the top wall 107 of the card hole 103. The first avoidance groove can increase the space above the card hole 103. In this way, when the clamping projection is inserted towards the card hole 103, it is not necessary to align with the card hole in the up-down direction, and the clamping projection 201 can be smoothly inserted into the card hole 103.

[0062] Optionally, a second avoidance groove is formed by partial downward depression of the bottom wall 108 of the card hole 103. The second avoidance groove can increase the space below the card hole 103. In this way, when the clamping projection is inserted towards the card hole 103, it is not necessary to align with the card hole in the up-down direction, and the clamping projection 201 can be smoothly inserted into the card hole 103.

[0063] Optionally, a first avoidance groove is provided on the top wall of the card hole 103, and a second avoidance groove is provided on the bottom wall of the card hole 103, so as to increase the space of the card hole 103 in both the up and down directions. In the left and right directions of the card hole, through the arrangement of the guiding surface and the guiding portion, when the card protrusion is inserted into the card hole, there is sufficient space in all four directions of up, down, left, and right, so that the card protrusion can be smoothly inserted into the card hole without additional positioning and alignment work.

[0064] Optionally, as Figure 6 shown, the top wall 107 of the card hole 103 includes a first top wall 1071 and a second top wall 1072. The second top wall 1072 is connected to the first top wall 1071 along the length direction of the card hole 103, and a first connection edge is formed at the connection of the first top wall 1071 and the second top wall 1072. Among them, both the first top wall 1071 and the second top wall 1072 are inclined upward toward the first connection edge, and the first top wall 1071 and the second top wall 1072 enclose the first avoidance groove.

[0065] In the embodiment of the present disclosure, the top wall 107 of the card hole 103 includes two sections, and both the first top wall 1071 and the second top wall 1072 are inclined and inclined upward toward the center, which is convenient for the processing of the first avoidance groove and can also increase the space above the card hole 103, facilitating the insertion of the card protrusion 201.

[0066] Optionally, the lengths of the positive projections of the first top wall 1071 and the second top wall 1072 in the horizontal direction are the same or different.

[0067] Optionally, as Figure 6 shown, the bottom wall 108 of the card hole 103 includes a first bottom wall 1081 and a second bottom wall 1082. The second bottom wall 1082 is connected to the first bottom wall 1081 along the length direction of the card hole 103, and a second connection edge is formed at the connection of the first bottom wall 1081 and the second bottom wall 1082. Among them, both the first bottom wall 1081 and the second bottom wall 1082 are inclined downward toward the second connection edge, and the first bottom wall 1081 and the second bottom wall 1082 enclose the second avoidance groove.

[0068] In the embodiment of the present disclosure, the bottom wall 108 of the card hole 103 is also divided into two sections, and both the first bottom wall 1081 and the second bottom wall 1082 are inclined downward toward the second connecting plate, so that the connection of the first bottom wall 1081 and the second bottom wall 1082 is the lowest, which can increase the space of the bottom wall 108 of the card hole 103, thereby forming the second avoidance groove and facilitating the insertion of the card protrusion 201 into the card hole 103.

[0069] Optionally, the lengths of the positive projections of the first bottom wall 1081 and the second bottom wall 1082 in the horizontal direction are the same or different.

[0070] Optionally, as Figure 2As shown, the enclosing panel 20 includes an enclosing panel 20 body and a second folded edge 207. The enclosing panel 20 body is configured with a clamping projection 201. The second folded edge 207 is provided at the lower peripheral edge of the enclosing panel 20 body. When the enclosing panel 20 is connected to the chassis 10, the second folded edge 207 abuts against the lower side of the chassis 10.

[0071] In an embodiment of the present disclosure, the enclosing panel 20 body is configured with a clamping projection 201. When the enclosing panel 20 is connected to the chassis 10, the enclosing panel 20 body fits against the outer side of the first folded edge 102. A second folded edge 207 is further provided below the enclosing panel 20 body. When the enclosing panel 20 and the chassis 10 are connected, the second folded edge 207 abuts against the lower side of the chassis 10. Thus, when installing the enclosing panel 20 and the base, the enclosing panel 20 is placed on the peripheral edge of the chassis 10. The second folded edge 207 of the enclosing panel 20 supports below the chassis 10, and the enclosing panel 20 body is located outside the first folded edge 102 of the chassis 10. The second folded edge 207 of the enclosing panel 20 can play a role in temporarily limiting the base, limiting the up and down direction of the chassis 10, and preventing the chassis 10 from moving downward. Then, the enclosing panel 20 body is pushed inward, so that the clamping projection 201 of the enclosing panel 20 body can be inserted into the clamping hole 103 of the first folded edge 102, thus realizing the connection between the enclosing panel 20 and the chassis 10. The second folded edge 207 limits the downward movement of the chassis 10, and the clamping projection 201 limits the upward movement of the chassis 10. In this way, the enclosing panel 20 and the chassis 10 are permanently limited in the up and down direction, and the enclosing panel 20 will not fall off. When subsequent operations are performed on the enclosing panel 20 and the chassis 10, there is no need to hold the enclosing panel 20 by hand, improving production efficiency.

[0072] Optionally, the second folded edge 207 extends annularly along the circumferential direction of the enclosing panel 20 body, which can improve the limiting effect on the downward direction of the chassis 10 from the circumferential direction.

[0073] Optionally, there are multiple second folded edges 207, and the multiple second folded edges 207 are arranged at intervals in sequence along the circumferential direction of the enclosing panel 20 body. This can also ensure the limiting effect of the second folded edge 207 on the downward movement of the chassis 10, and at the same time can save materials and reduce costs.

[0074] Optionally, as Figure 8 shown, the enclosing panel 20 is provided with a notch 205. One end of the clamping projection 201 is connected to the bottom wall 108 of the notch 205, and the clamping projection 201 extends from the bottom wall 108 of the notch 205 towards the installation space 30.

[0075] In an embodiment of the present disclosure, the clamping projection 201 is formed by bending a part of the enclosing panel 20 towards the inside of the installation space 30. This not only saves costs, but also facilitates the production of the clamping projection 201. And in this way, the clamping projection 201 and the enclosing panel 20 are integrated, which can improve the connection and fixation between the clamping projection 201 and the enclosing panel 20, prevent the clamping projection 201 from separating from the enclosing panel 20, and ensure the stability of the connection and limitation between the enclosing panel 20 and the base.

[0076] Optionally, the clamping projection 201 can also be of other shapes, for example, it can be arranged vertically.
