DETAILED DESCRIPTION

[0035] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "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 application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0038] In the description of this application, 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 this application can be understood according to specific circumstances.

[0039] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0040] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0041] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0042] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0043] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0044] like Figure 1-Figure 10 As shown, the first aspect of the embodiment of the present application proposes an air-conditioning indoor unit, comprising: an indoor unit body 1, an electric control box 2, an outer cover 3, a box cover 4 and a panel 5, wherein the electric control box 2 is installed on the indoor unit body 1, the outer cover 3 is buckled on the upper side of the indoor unit body 1, the outer cover 3 is provided with a first mounting hole 31, the first mounting hole 31 is located on the upper side of the electric control box 2, the box cover 4 is installed at the first mounting hole 31, and is used to cover and shield the electric control box 2, and the panel 5 is covered on the upper side of the outer cover 3; The outer cover 3 has a first shielding portion 32 extending circumferentially along the inner wall of the first mounting hole 31, and the box cover 4 has a second shielding portion 41 extending circumferentially along the outer wall of the box cover 4, and the first shielding portion 32 is located below the second shielding portion 41, wherein a space-avoiding groove 321 is provided at a corner position of the first shielding portion 32, and the second shielding portion 41 has a straight line segment 411 extending in a straight line and a bending segment 412 located between two adjacent straight line segments 411, and the bending segment 412 is located at the space-avoiding groove 321.

[0045] Based on the above technical solution, the air-conditioning indoor unit and air conditioner of the present application, the indoor unit body 1 serves as a base, the electric control box 2 is installed on the indoor unit body 1, the outer cover 3 is provided with a first mounting hole 31 corresponding to the mounting position of the electric control box 2, the box cover 4 of the electric control box 2 is installed on the first mounting hole 31 for shielding the electric control box 2, the panel 5 is located at the outermost side, covering the outer cover 3, forming an integral air-conditioning indoor unit, in order to enable the outer cover 3 and the box cover 4 to completely shield and protect the interior of the air conditioner, a first shielding portion 32 is further provided at the position of the first mounting hole 31 of the outer cover 3, and the box cover 4 is provided with a first shielding portion 32. A second shielding portion 41 is provided at the corresponding position, and the two shielding portions staggeredly shield the first mounting hole 31, which is safer, and the air-avoiding groove 321 is located at a corner position, which is also the installation position of the bending section 412 of the second shielding portion 41. Although the strength of the bending section 412 is relatively weak, the position of the bending section 412 corresponds to the air-avoiding groove 321, and there will be no direct collision with the second shielding portion 41, and the bending section 412 will not be damaged by force, thereby improving the stability and reliability of the first shielding portion 32 during transportation and when it falls. In addition, preferably, the first shielding portion 32 is set as a rib structure, and the second shielding portion 41 is set as a flange structure, which is simple in structure and easy to process.

[0046] It should be noted that the indoor unit of the split wall-mounted air conditioner is usually installed on the wall, and the panel 5 is located on the side away from the wall. However, during transportation, the indoor unit of the air conditioner is usually placed flat, that is, the back of the indoor unit is facing down. In this case, the indoor unit body 1-outer cover 3-panel 5 are installed in sequence from bottom to top, that is, the outer cover 3 is buckled on the upper side of the indoor unit body 1, and the panel 5 covers the upper side of the outer cover 3.

[0047] In some embodiments of the present application, Figure 7-10 As shown, the bending section 412 is inclined near one side of the first shielding portion 32, and the outer side of the bending section 412 is farther away from the first shielding portion 32 than the inner side of the bending section 412. When the box cover 4 is displaced, when the second shielding portion 41 on the box cover 4 collides with the first shielding portion 32 at the position of the first mounting hole 31 of the outer cover 3, the bevel of the bending section 412 of the second shielding portion 41 plays a guiding role. Since the direction of the inclination is gradually inclined upward from the inside to the outside, the box cover 4 can avoid frontal impact and prevent the bending section 412 from being damaged. At the same time, the bending section 412 can return to the position of the first mounting hole 31 along the inclined surface, and then the box cover 4 can smoothly return to the installation position of the electric control box 2.

[0048] Specifically, Figure 7-10As shown, the straight section 411 is tilted near the side of the first shielding portion 32, and the outer side of the straight section 411 is farther away from the first shielding portion 32 than the inner side of the straight section 411. On the basis of the bottom of the bent section 412 being tilted, the straight section 411 of the second shielding portion 41 is also tilted gradually upward from the inside to the outside. Such a flanging structure makes the guiding effect of the second shielding portion 41 more obvious. No matter which direction the air conditioner indoor unit moves during transportation, the bottom of the second shielding portion 41 is tilted to make the box cover 4 return to the first mounting hole 31, and the transportation process is more stable and reliable.

[0049] Specifically, Figure 7-10 As shown, the bending section 412 is a structure that extends continuously in the circumferential direction or a structure composed of a plurality of inclined ribs arranged at intervals in the circumferential direction. In the actual manufacturing process, in order to improve the adaptability of the bending section 412 of the second shielding portion 41, the bending section 412 can be made of a solid body or by combining a plurality of inclined ribs. No matter which method is used, it is only necessary to make the bending section 412 have a guiding function to ensure that it can slide into the first mounting hole 31 along the upper side edge of the first mounting hole 31.

[0050] In some embodiments of the present application, Figure 1 , Figure 4 As shown, when viewed downward along the first mounting hole 31, the inner side wall of the first shielding portion 32 is located inside the outer side wall of the second shielding portion 41. The first shielding portion 32 on the inner peripheral wall of the first mounting hole 31 extends toward the inner side of the first mounting hole 31, and the second shielding portion 41 on the outer peripheral wall of the box cover 4 extends toward the outer side of the first mounting hole 31. In order to completely shield the first mounting hole 31, it is necessary to make the longitudinal projections of the first shielding portion 32 and the second shielding portion 41 coincide with each other, or to make the inner peripheral wall of the first shielding portion 32 and the outer peripheral wall of the second shielding portion 41 fit together. In this way, the first mounting hole 31 can be completely shielded, the internal structure of the air conditioner can be protected, and debris can be prevented from entering the air conditioner to damage the electric control box 2 and the internal structure of the electric control box 2.

[0051] In some embodiments of the present application, Figure 2 As shown, the first shielding portion 32 includes a high block 322 and a low block 323 connected in a circumferential direction, the top surface of the high block 322 is higher than the top surface of the low block 323, and the top surface of the low block 323 and the side surface of the adjacent high block 322 together define the air-avoiding groove 321. There is a height difference between the high block 322 and the low block 323, but the high block 322 and the low block 323 are connected in the circumferential direction, which will not affect the shielding effect, and at the same time can conveniently and effectively form the air-avoiding groove 321, with a simple structure and convenient molding.

[0052] In some embodiments of the present application, Figure 7-10 As shown, the box cover 4 includes a cover body 42, a snap-in block 43, and the second shielding portion 41 located outside the cover body 42 and the snap-in block 43.

The box cover 4 is composed of three parts. The cover body 42 is the main shielding component of the first mounting hole 31, which can shield most of the first mounting hole 31 and protect the electric control box 2. The clamping block 43 located below the cover body 42 is connected to the electric control box 2 and plays a role in installation limit. The second shielding part 41 located on the outside of the two forms a flange structure, which not only plays a role in structural reinforcement, but also can cooperate with the first shielding part 32 to achieve complete shielding of the first mounting hole 31, and can be kept above the first shielding part 32 when the box cover 4 and the electric control box 2 are not fixed, so as to cover the first mounting hole 31, which is convenient for transportation and installation after transportation. Preferably, the cover body 42 and the clamping block 43 are connected at 90°, and the second shielding part 41 and the clamping block 43 are also connected at 90°. The structure is simple, easy to make, and has a certain aesthetic appearance.

[0053] Specifically, Figure 7-10 As shown, the cover body 42 is provided with a second mounting hole 421, and the cover body 42 passes through the second mounting hole 421 and is connected to the electric control box 2 through a fastener, so as to fix the box cover 4 on the electric control box 2.

The shape of the first mounting hole 31 corresponds to the shape of the electric control box 2, and adopts a quadrilateral structure. The box cover 4 also adopts a quadrilateral structure, which can better protect the electric control box 2 and does not occupy the installation space of other structures. In addition, the L-shaped air avoidance groove 321 has a simple structure and can simply and effectively realize the anti-collision function of the bent portion.
