Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 belong to the scope of protection of the present utility model.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, then the directional indications will also change accordingly.

[0034] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. 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 such feature. In addition, the meaning of "and / or" appearing throughout the text 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 various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. 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 scope of protection required by the present utility model.

[0036] As Figures 1-7 shown, the present utility model provides an indoor unit, which includes an indoor unit main body, an electric control box side cover 200, and a main control mounting seat 100. The electric control box side cover 200 cooperates with the side wall of the indoor unit main body to form an accommodation space 20. The main control mounting seat 100 is used for mounting the main board, and the main control mounting seat 100 is arranged in the accommodation space 20. The main control mounting seat 100 is rotatably connected to the side wall of the accommodation space 20. The main control mounting seat can be rotated out of the accommodation space 20 along a first direction, and the main control mounting seat 100 can be rotated into the accommodation space 20 along a second direction, and the first direction and the second direction are opposite directions.

[0037] It can be understood that by the cooperation between the electric control box side cover 200 and the side wall of the indoor unit main body to form the accommodation space 20, instead of using the electric control box to accommodate the main control mounting seat 100, the main board is arranged in the accommodation space 20, and then through the rotational connection between the main control mounting seat 100 and the side wall of the accommodation space 20, the rotation out and rotation in of the main control mounting seat 100 are realized. When maintenance is required, the main control mounting seat 100 can be rotated out of the accommodation space 20 for maintenance, reducing the maintenance workload of the main board in the electric control box and improving the maintenance efficiency.

[0038] It should be noted that the side wall of the Rong'an space can be the side cover 200 of the electric control box or the side wall of the indoor unit main body. The main control mounting seat 100 is rotatably connected to any one of them, so that the main control mounting seat 100 can be rotated out and into the accommodation space 20. Generally, in order to ensure that the main control mounting seat 100 can be completely rotated out of the Rong'an space, the accommodation space 20 is slightly larger than the main control mounting seat 100, and the rotational connection between the main control mounting seat and the side wall of the accommodation space 20 is located at the bottom corner of the main control mounting seat 100.

[0039] In some embodiments, the main control mounting seat 100 is rotatably connected to the side cover 200 of the electric control box.

[0040] In some embodiments, the accommodation space 20 formed by the cooperation of the side cover 200 of the electric control box and the indoor unit main body encloses the top and the periphery of the main control mounting seat 100, so that the main control mounting seat 100 can be rotated out from the bottom wall of the accommodation space 20.

[0041] In some embodiments, either the rotating shaft hole 320 or the rotating shaft 310 is provided on the main control mounting seat 100, and the other of the rotating shaft hole 320 and the rotating shaft 310 is provided on the side wall of the accommodation space 20. The rotating shaft hole 320 is rotatably connected to the rotating shaft 310 so that the main control mounting seat 100 is rotatably connected to the side wall of the accommodation space 20.

[0042] The first limiting portion and the second limiting portion are respectively provided on the rotating shaft 310 and the rotating shaft hole 320. When the main control mounting seat 100 rotates to the target position, the first limiting portion is in limiting connection with the second limiting portion so that the main control mounting seat 100 remains in the target position.

[0043] Generally, the limiting connection manner between the first limiting portion and the second limiting portion is snap connection, so that the main control mounting seat 100 can hover during the process of rotating out or rotating in.

[0044] In some embodiments, the rotating shaft 310 is provided on the side cover 200 of the electric control box, and the rotating shaft hole 320 is provided on the main control mounting seat 100.

[0045] In some embodiments, a damping protrusion 30 is provided on the rotating shaft 310, and a plurality of damping grooves 40 are provided on the inner wall of the rotating shaft hole 320 and are equally spaced in the circumferential direction. When the main control mounting seat 100 rotates, the damping protrusion 30 moves between the damping grooves 40. When the main control mounting seat 100 rotates to the target position, the damping protrusion 30 is snapped into the damping groove 40 so that the main control mounting seat 100 remains in the target position.

[0046] That is, by providing the damping grooves 40 and the damping protrusions 30, when the rotating shaft 310 rotates relative to the rotating shaft hole 320, there are multiple clamping positions. That is, without external force, the damping protrusions 30 will not slide out of the damping grooves 40, so that the main control mounting base 100 has multiple target positions relative to the side wall of the accommodating space 20 and can hover at the rotating positions. At the same time, by providing the damping protrusions 30 and the damping grooves 40, the rotation speed of the main control mounting base 100 can be slowed down to avoid excessive rotation.

[0047] In some embodiments, a damping groove 40 is provided on the rotating shaft 310, and a plurality of damping protrusions 30 are provided on the inner wall of the rotating shaft hole 320 and are evenly distributed along the circumferential direction. When the main control mounting base rotates, the damping protrusions 30 move between the damping grooves 40. When the main control mounting base 100 rotates to the target position, the damping protrusions 30 are clamped in the damping grooves 40 to keep the main control mounting base 100 at the target position.

[0048] In some embodiments, a plurality of damping protrusions 30 are provided on the rotating shaft 310 and are evenly distributed along the circumferential direction thereof, and a damping groove 40 is provided on the inner wall of the rotating shaft hole 320. When the main control mounting base rotates, the damping protrusions 30 move between the damping grooves 40. When the main control mounting base 100 rotates to the target position, the damping protrusions 30 are clamped in the damping grooves 40 to keep the main control mounting base 100 at the target position.

[0049] In some embodiments, a plurality of damping grooves 40 are provided on the rotating shaft 310 and are evenly distributed along the circumferential direction thereof, and a damping protrusion 30 is provided on the inner wall of the rotating shaft hole 320. When the main control mounting base rotates, the damping protrusion 30 moves between the damping grooves 40. When the main control mounting base 100 rotates to the target position, the damping protrusion 30 is clamped in the damping groove 40 to keep the main control mounting base 100 at the target position.

[0050] In some embodiments, a plurality of damping protrusions 30 are provided on the rotating shaft 310 and are evenly distributed along the circumferential direction thereof, a plurality of damping grooves 40 are provided on the rotating shaft 310 and are evenly distributed along the circumferential direction thereof, and the inner wall of the rotating shaft hole 320 is provided with damping grooves 40 equal in number to the damping protrusions 30. When the main control mounting base rotates, the damping protrusions 30 move between the damping grooves 40. When the main control mounting base 100 rotates to the target position, each damping protrusion 30 is respectively clamped in a damping groove 40 to keep the main control mounting base 100 at the target position.

[0051] In some embodiments, a plurality of damping grooves 40 are provided on the rotating shaft 310 at equal intervals in the circumferential direction thereof, and a plurality of damping protrusions 30 are provided on the rotating shaft 310 at equal intervals in the circumferential direction thereof. Damping grooves 40 equal in number to the damping protrusions 30 are provided on the inner wall of the rotating shaft hole 320. When the main control mounting base rotates, the damping protrusions 30 move between the damping grooves 40. When the main control mounting base 100 rotates to the target position, each damping protrusion 30 is respectively clamped in a damping groove 40 so that the main control mounting base 100 is held at the target position.

[0052] In some embodiments, a first wire 500 is connected between the electrical module of the indoor unit and the main board on the main control mounting base 100. The first wire 500 is used for electrically connecting the main board and the electrical module. An elastic restraint is sleeved on the first wire 500. The elastic restraint is used to gradually unfold when the first wire 500 rotates out with the main control mounting base 100 so as to unfold the first wire 500, and gradually fold when the first wire 500 rotates into the main control mounting base 100 so as to fold the first wire 500.

[0053] It can be understood that by using the elastic restraint 50 to restrict the change of the first wire 500, it is avoided that the wiring becomes messy after the main control mounting base 100 rotates out and in, resulting in damage to the first wire 500.

[0054] That is, the elastic restraint 50 can adopt a semi-circular elastic sleeve. The first wire 500 extends as the main control mounting base 100 rotates out, and folds into a ring again as the main control mounting base 100 rotates in.

[0055] In some embodiments, the elastic restraint 50 is configured to gradually unfold into a "one" - shaped structure as the main control mounting base 100 rotates out, and gradually fold into a "V" - shaped structure as the main control mounting base 100 rotates in.

[0056] It can be understood that unfolding from a "V" - shaped to a "one" - shaped is more in line with the mechanical properties of the wire, enabling the wire to unfold and fold along a predetermined path and preventing the first wire 500 from extending into other components of the indoor unit.

[0057] In some embodiments, the elastic restraint 50 includes a first restraint portion 51, a second restraint portion 52, and an elastic portion. One end of the first restraint portion 51 is rotatably connected to one end of the second restraint portion 52, and an elastic portion is connected between them. The elastic portion is configured to make the first restraint portion 51 and the second restraint portion 52 in a "V" - shaped structure when the elastic restraint 50 is not subjected to an external force.

[0058] Specifically, the elastic part includes a first elastic sub - part 511, a second elastic sub - part 521, and a connecting shaft 54. The first elastic sub - part 511 is arranged at the end of the first constraint part 51 and is an elastic sheet. The second elastic sub - part 521 is arranged at the end of the second constraint part 52 and is an elastic sheet. When the first constraint part 51 is connected to the second constraint part 52, the first elastic sub - part 511 and the second elastic sub - part 521 are arranged in a crossed manner. While the connecting shaft 54 passes through the first constraint part 51 and the second constraint part 52 in sequence, the connecting shaft 54 also passes through the first elastic sub - part 511 and the second elastic sub - part 521 in sequence, enabling the first constraint part 51 and the second constraint part 52 to be rotatably connected while having a tensile force between the first constraint part 51 and the second constraint part 52, so that the first constraint part 51 and the second constraint part 52 form a "V" - shaped structure.

[0059] Specifically, the elastic part can adopt a micro - spring. One end of the micro - spring is connected to the first constraint part 51, and the other end of the micro - spring is connected to the second constraint part 52.

[0060] In some embodiments, a plurality of first wire - clamping buckles 53 are arranged on the elastic constraint member 50. The plurality of first wire - clamping buckles 53 are spaced apart along its length direction. The first wire 500 passes through the plurality of first wire - clamping buckles 53 in sequence, so that the elastic constraint member 50 is sleeved on the first wire 500.

[0061] Specifically, for example, the first wire - clamping buckles 53 are arranged on the outer sides of both the first constraint part 51 and the second constraint part 52.

[0062] In some embodiments, a second wire 600 is arranged on the periphery of the main - control mounting base 100. One end of the second wire 600 is connected to the first wire 500. The second wire 600 is used to connect the main board and the first wire 500. A plurality of second wire - clamping buckles 110 are arranged on the outer side of the main - control mounting base 100. The second wire - clamping buckles 110 are used to bind the second wire 600.

[0063] It can be understood that by arranging the second wire 600 on the periphery of the main - control mounting base 100, the situation where the second wire 600 is arranged inside and is prone to interference with the second wire 600 is avoided.

[0064] In some embodiments, the indoor unit further includes a bottom cover 700. The bottom cover 700 is connected to the bottom of the main - control mounting base 100. The bottom cover 700 is used to connect to the indoor unit after the main - control mounting base 100 is screwed into the accommodation space 20 to close the accommodation space 20.

[0065] In some embodiments, the present utility model further provides an air conditioner, including the above - mentioned indoor unit.

[0066] Since the air conditioner includes the indoor unit of the above-mentioned embodiment or combined embodiment, it has at least some or all of the beneficial effects of the above-mentioned indoor unit, which will not be elaborated one by one here.

[0067] The above are only alternative embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the application concept of the present invention, or direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
