[0011] a covering cover, the covering cover and the electric control box enclose a protection cavity, and at least part of the transition section is located in the protection cavity.

[0012] By arranging the electric control box on the casing and outside the containing cavity, compared with the way of arranging the electric control box in the containing cavity of the casing, on the one hand, the maintenance of the electric control box becomes simple, and on the other hand, no space is needed in the containing cavity for placing the electric control box, so that the casing can be designed to be relatively small.

[0013] In addition, by covering part of the transition section with the covering cover, the covering cover can protect the transition section, so that the environment of the transition section of the cable is relatively safe. On the one hand, the safety hazards such as cable fire or electric shock can be avoided, and on the other hand, the air conditioner indoor unit will also have no messy cables from the appearance, so that the wiring of the air conditioner indoor unit is more neat and the appearance performance is better.

[0014] Optionally, an air conditioner indoor unit comprises:

[0015] A shell is used for ceiling mounting, and a containing cavity is formed in the shell;

[0016] An air outlet and an air inlet are arranged on the shell and communicate with the containing cavity, the air inlet is located at the rear side of the shell, and the air outlet is arranged opposite to the air inlet;

[0017] A motor is located in the containing cavity;

[0018] An electric control box is arranged on the shell and located outside the containing cavity, and an opening is further arranged on the shell and communicates with the containing cavity;

[0019] A cable is connected between the motor and the electric control box through the opening, and the cable comprises a transition section exposed outside the containing cavity and the electric control box;

[0020] A covering cover is used for covering at least part of the transition section.

[0021] By arranging the electric control box on the shell and outside the containing cavity, compared with the mode that the electric control box is arranged in the containing cavity of the shell, on the one hand, the maintenance of the electric control box becomes simpler, and on the other hand, no space is needed in the containing cavity for placing the electric control box, so that the shell can be designed to be relatively small.

[0022] In addition, by covering part of the transition section with the covering cover, the covering cover can protect the transition section, so that the environment of the transition section of the cable is relatively safe. On the one hand, the safety hazards such as cable fire or electric shock can be avoided, and on the other hand, the air conditioner indoor unit will also have no messy cables from the appearance, so that the wiring of the air conditioner indoor unit is more neat and the appearance performance is better.

[0023] Optionally, the opening is a maintenance opening for maintaining the motor.

[0024] By making the opening a maintenance opening for maintaining the motor, the opening can be used for maintaining the motor in addition to being used for passing the cable. In other words, the cable and the maintenance of the motor can share the opening, so that a separate opening for the cable need not be formed on the casing, but the maintenance opening can be directly used.

[0025] In this way, on the one hand, the manufacturing cost of the opening for the cable formed on the casing can be reduced, and on the other hand, the mechanical strength of the casing can be improved, so that the casing is more solid and durable.

[0026] Optionally, the edge of the opening is a dead edge.

[0027] By making the edge of the opening a dead edge, the edge of the opening is relatively blunt and not too sharp, so that the edge of the opening can not cut the cable and the personnel.

[0028] Optionally, the control box covers part of the opening, and the cable is connected between the control box and the motor through the remaining part of the opening.

[0029] By making the control box cover part of the opening, when the control box is installed on the casing, the control box can also shield the opening, so that a special structure for shielding the opening need not be designed, the control box can serve multiple purposes, the structure of the air conditioner indoor unit can be simplified, the number of parts of the air conditioner indoor unit can be reduced, and the cost of the air conditioner indoor unit can be reduced.

[0030] Optionally, the cover covers the remaining part of the opening.

[0031] By making the cover cover the remaining part of the opening, when the control box and the cover are both installed on the casing, the entire opening can be completely covered by the control box and the cover. In this way, on the one hand, dust and the like can be prevented from entering the accommodation cavity through the opening, so that the operating environment of the motor in the accommodation cavity is cleaner and less likely to be contaminated by dust. At the same time, the air conditioner indoor unit can be made more neat and beautiful in appearance.

[0032] Optionally, the cover is detachably arranged on the casing or the control box.

[0033] By making the cover detachably arranged on the casing or the control box, when the cable covered in the cover needs to be maintained due to an abnormality during the operation of the air conditioner indoor unit, the cover can be detached to expose the cable for maintenance. After the cable is maintained, the cover can be reinstalled.

[0034] It can be seen that by detachably arranging the covering cover on the casing or the electric control box, the maintenance of the cable can be very convenient.

[0035] Optionally, the covering cover comprises:

[0036] a cover body part, the cover body part and the electric control box form a protection cavity, at least part of the transition section is located in the protection cavity to cover at least part of the transition section;

[0038] a first locking part, the first locking part is arranged on the cover body part, and the first locking part is detachably locked on the casing.

[0039] By arranging the first to-be-inserted part on the casing and arranging the first insertion part on the cover body part, the cooperation between the first insertion part and the first to-be-inserted part can play a role of pre-positioning when the covering cover is installed on the casing. Therefore, the installation precision of the covering cover when installed on the casing is higher.

[0040] After the first insertion part is arranged in the first to-be-inserted part, the cover body part is locked on the casing through the first locking part. This installation mode can ensure the installation precision and also simplify the installation difficulty and reduce the installation steps to a certain extent.

[0041] Optionally, the cover body part comprises:

[0042] a bottom wall, the bottom wall is spaced apart from the electric control box;

[0043] a surrounding wall, the surrounding wall is arranged on part of the circumference of the bottom wall along the circumferential direction of the bottom wall, and an end of the surrounding wall away from the bottom wall faces the electric control box, so that the bottom wall, the surrounding wall and the electric control box form the protection cavity, and an end of the bottom wall without the surrounding wall faces the opening.

[0044] By arranging the end of the bottom wall without the surrounding wall to face the opening, the protection cavity can be communicated with the containing cavity through the opening. Therefore, the structure is provided for the cable in the protection cavity to enter the containing cavity through the opening, and the cable can enter the containing cavity as straight as possible.

[0045] Optionally, the end of the bottom wall without the surrounding wall abuts against the casing, and two ends of the surrounding wall opposite to each other along the circumferential direction of the surrounding wall also abut against the casing.

[0046] By making the two ends of the surrounding wall along the circumferential direction of the surrounding wall also abut against the shell, the sealing between the two ends of the surrounding wall along the circumferential direction of the surrounding wall and the shell is also good, and the sealing of the protection cavity is further improved to a certain extent, so that the dust from the outside can be further avoided or reduced from entering the protection cavity.

[0047] Optionally, the first insertion part and the first locking part are respectively arranged at the two ends of the surrounding wall along the circumferential direction of the surrounding wall.

[0048] By arranging the first insertion part and the first locking part at the two ends of the surrounding wall along the circumferential direction of the surrounding wall, the two ends of the surrounding wall along the circumferential direction of the surrounding wall can be fixed on the shell under the action of the first insertion part and the first locking part, that is, the two free ends of the cover can be fixed under the action of the first insertion part and the first locking part. In this way, the cover can be more stably and reliably installed on the shell.

[0049] Optionally, the first insertion part is a first insertion sheet, and the first insertion sheet is inserted into the first insertion part along a direction parallel to the first shell surface, wherein the first shell surface refers to the surface of the shell at the first insertion part.

[0050] In the case where the first insertion part is a first insertion sheet, by inserting the first insertion sheet into the first insertion part along a direction parallel to the first shell surface, the entire first insertion part can be arranged close to the surface of the shell without penetrating into the insertion accommodating cavity of the shell, so that the first insertion part does not occupy or less occupies the space of the accommodating cavity, thereby avoiding the mutual interference between the first insertion part and the motor in the accommodating cavity to a certain extent.

[0051] Optionally, the electric control box comprises:

[0052] a box body, the box body is detachably arranged on the shell; and

[0053] a control assembly, the control assembly is arranged in the box body, and the cable of the control assembly is connected between the motor and the control assembly through the opening.

[0054] Since the control assembly is arranged in the box body, the box body can protect the control assembly, so that the operation of the control assembly is more secure.

[0055] In addition, by detachably arranging the box body on the shell, when the electric control box needs to be maintained, the box body can be detached from the shell for maintenance, which is very convenient.

[0056] Optionally, the box body is provided with a second insertion part, and the shell is provided with a second to-be-inserted part matched with the second insertion part.

[0057] The second insertion part is pluggably inserted into the second to-be-inserted part along a direction parallel to a second shell surface, which is a surface of the shell at the second to-be-inserted part.

[0058] By providing the second insertion part on the box body and the second to-be-inserted part matched with the second insertion part on the shell, when the second insertion part is pluggably inserted into the second to-be-inserted part, the second insertion part and the second to-be-inserted part are matched with each other, which can play a role of pre-positioning, so that the installation precision of the box body on the shell is higher. On the other hand, the plug-in mode is simple to operate, so that the process flow of installing the box body on the shell can be simplified to a certain extent.

[0059] Optionally, the shell is provided with a locking piece abutting against an end of the box body away from the second insertion part, and a surface of the locking piece is perpendicular to an insertion direction of the second insertion part, and the locking piece is detachably locked to the box body.

[0060] By abutting the locking piece against the end of the box body away from the second insertion part and making the surface of the locking piece perpendicular to the insertion direction of the second insertion part, the box body can be limited between the second to-be-inserted part and the locking piece, so that the second insertion part cannot abnormally slide out of the second to-be-inserted part in a direction away from the insertion direction of the second insertion part under the limiting action of the locking piece, and the box body can be more stably installed on the shell.

[0092] The air conditioner indoor unit is a device capable of blowing cold or hot air to regulate the indoor temperature. In the related art, the air conditioner indoor unit usually includes a casing and an electric control box, and the electric control box is arranged in the casing. However, if the electric control box is arranged in the casing, the casing needs to be opened before maintenance when the electric control box is abnormal, and the maintenance is relatively difficult. On the other hand, arranging the electric control box in the casing will inevitably occupy the space inside the casing, resulting in a relatively large size of the casing, which is not flexible enough. Based on this, the embodiments of the present application provide a new air conditioner indoor unit to solve the above problems.

[0093] The technical solutions of the present application will be described below in conjunction with specific embodiments and drawings.

[0094] Figure 1 is a structural schematic diagram of an air conditioner indoor unit 100 provided by an embodiment of the present application, Figure 2 is Figure 1 is a structural schematic diagram of the air conditioner indoor unit 100 in another view in Figure 1 and Figure 2 The air conditioner indoor unit 100 includes a casing 1, and the casing 1 forms a receiving cavity 10.

[0095] The material of the casing 1 can be plastic or metal, and the embodiments of the present application do not limit the material of the casing 1. The shape of the casing 1 can be a cuboid or a cylinder, and the embodiments of the present application do not limit the shape of the casing 1.

[0096] By forming the accommodating cavity 10 in the casing 1, the accommodating cavity 10 can provide convenience for accommodating various components (such as a fan, a motor, an evaporator, etc.) of the air conditioner indoor unit 100 therein, and when the various components of the air conditioner indoor unit 100 are accommodated in the accommodating cavity 10, the casing 1 can protect the various components of the air conditioner indoor unit 100, so that the operating environment of the various components of the air conditioner indoor unit 100 is safer.

[0097] In some embodiments, referring to Figure 1 and Figure 2 , the casing 1 is provided with an air outlet 12 and an air inlet 11 which communicate with the accommodating cavity 10.

[0098] By providing the air inlet 11 and the air outlet 12 on the casing 1 which communicate with the accommodating cavity 10, the air inlet 11 can be used for air to enter the accommodating cavity 10, and the air outlet 12 can be used for air to be discharged from the accommodating cavity 10.

[0099] It can be seen that by providing the air inlet 11 and the air outlet 12 on the casing 1 which communicate with the accommodating cavity 10, air can be very conveniently introduced into the accommodating cavity 10 through the air inlet 11 and discharged from the accommodating cavity 10 through the air outlet 12, thereby providing structural protection for subsequent ensuring that the air conditioner indoor unit 100 can suck indoor air into the accommodating cavity 10 through the air inlet 11 for temperature adjustment, and discharge the air adjusted in temperature from the accommodating cavity 10 to the indoor through the air outlet 12.

[0100] In some embodiments, the air inlet 11 is located at the rear side of the casing 1, and the air outlet 12 is oppositely arranged with the air inlet 11.

[0101] Among them, the rear side of the casing 1 refers to the back side of the casing 1 when the air conditioner indoor unit 100 is ceiling-mounted.

[0102] Since the air inlet 11 is located at the rear side of the casing 1, and the air outlet 12 is oppositely arranged with the air inlet 11, the air inlet 11 will be located at the front side of the casing 1. In this way, when the air conditioner indoor unit 100 is ceiling-mounted, neither the air outlet 12 nor the air inlet 11 will be blocked by the roof, thereby ensuring the normal operation of the air conditioner indoor unit 100 and providing structural protection for the ceiling-mounted installation of the air conditioner indoor unit 100.

[0103] In some embodiments, referring to Figure 1 and Figure 2 , the casing 1 comprises a front shell 17 and a rear shell 18, and the rear shell 18 is oppositely arranged with the front shell 17.

[0104] In the case of ceiling-mounted installation of the air conditioner indoor unit 100, the rear shell 18 refers to the shell body (i.e., the rear shell body) of the casing 1 which faces the vertical wall, and the front shell 17 refers to the shell body (i.e., the front shell body) of the casing 1 which is away from the vertical wall.

[0105] In some embodiments, please continue to refer to Figure 1 and Figure 2 , the front shell 17 is provided with an air outlet 12 which communicates with the accommodating cavity 10, and the rear shell 18 is provided with an air inlet 11 which communicates with the accommodating cavity 10.

[0106] By setting the air outlet 12 on the front shell 17 and setting the air inlet 11 on the rear shell 18, the air conditioner indoor unit 100 can be installed on the ceiling without the air outlet 12 and / or the air inlet 11 being blocked by the roof, so that the air conditioner indoor unit 100 is convenient to install on the ceiling.

[0107] In some embodiments, please refer to Figure 1 and Figure 3 , Figure 3 is Figure 1 an exploded view of the air conditioner indoor unit 100 in

[0108] Since part of the evaporator 2 is located in the accommodating cavity 10, under the action of the evaporator 2, the air entering the accommodating cavity 10 can be tempered, such as being cooled.

[0109] In this way, when the air conditioner indoor unit 100 is applied indoors, the indoor air can be tempered.

[0110] In some embodiments, please refer to Figure 3 , the air conditioner indoor unit 100 comprises a motor 21, and the motor 21 is located in the accommodating cavity 10.

[0111] The working process of the motor 21 can be roughly as follows: first, the motor 21 can drive the fan to suck air into the accommodating cavity 10 through the air inlet 11, then the evaporator 2 can act to temper the air entering the accommodating cavity 10, and finally the motor 21 can drive the fan to discharge the tempered air out of the accommodating cavity 10 through the air outlet 12.

[0112] By locating the motor 21 in the accommodating cavity 10, on the one hand, the motor 21 can be protected by the motor 21 on the periphery of the motor 21, so that the operating environment of the motor 21 is more secure.

[0113] In some embodiments, please refer to Figure 1 and Figure 3 , the air conditioner indoor unit 100 further comprises an electric control box 22, and the electric control box 22 is arranged on the motor housing 1 and located outside the accommodating cavity 10.

[0114] By setting the electric control box 22 outside the accommodating cavity 10 of the casing 1, on the one hand, the maintenance of the electric control box 22 will be simpler compared with the way of setting the electric control box 22 in the accommodating cavity 10 of the casing 1, on the other hand, no space is needed to be reserved in the accommodating cavity 10 for placing the electric control box 22, so that the casing 1 can be designed smaller.

[0115] In some embodiments, referring to Figure 1 , Figure 4 and Figure 5 , Figure 4 is Figure 1 another exploded view of the air conditioner indoor unit 100, Figure 5 is Figure 1 still another exploded view of the air conditioner indoor unit 100, the casing 1 is further provided with an opening 13 communicating with the accommodating cavity 10, referring to Figure 6 , Figure 6 is Figure 5 a partial enlarged view of the position C, the cable 221 is connected between the motor 21 and the electric control box 22 through the opening 13.

[0116] Since the electric control box 22 is located outside the accommodating cavity 10 and the motor 21 is arranged in the accommodating cavity 10, by setting the opening 13 on the casing 1 communicating with the accommodating cavity 10, the cable 221 can be very conveniently connected between the motor 21 and the electric control box 22 through the opening 13, so that the electric control box 22 can control the motor 21 to achieve the corresponding function.

[0117] For example, the electric control box 22 can control the motor to start action, and then drive the fan to start action, so as to achieve the purpose of absorbing air from the air inlet 11 into the accommodating cavity 10 for temperature adjustment, and discharging the air after temperature adjustment from the air outlet 12 out of the accommodating cavity 10.

[0118] In some embodiments, referring to Figure 5 and Figure 7 , Figure 7 is Figure 5 a structural schematic view of the air conditioner indoor unit 100 in another perspective, the cable 221 includes a transition section 2211 exposed outside the accommodating cavity 10 and the electric control box 22, the air conditioner indoor unit 100 further includes a cover 23, the cover 23 and the electric control box 22 enclose a protection cavity 20, and at least part of the transition section 2211 is located in the protection cavity 20.

[0119] Since the cover 23 and the electrical control box 22 enclose a protective cavity 20, at least part of the transition section 2211 is located inside the protective cavity 20. Therefore, the cover 23 can cover at least part of the transition section 2211. With this arrangement, the cover 23 can protect the transition section 2211, making the environment of the transition section 2211 of the cable 221 safer. On the one hand, it can avoid safety hazards such as cable 221 catching fire or electric shock. On the other hand, from the appearance, the air conditioner indoor unit 100 will also be free of messy cables 221. Therefore, the wiring of the air conditioner indoor unit 100 is neater and the appearance is better.

[0120] The material of the aforementioned cover 23 can be plastic, metal or any other possible material, as long as it can serve the purpose of protecting the transition section 2211 of the cable 221. This embodiment does not limit this.

[0121] It is understood that when the motor 21 is located in the accommodating cavity 10, the cable connecting the electrical control box 22 and the motor 21 is the motor cable. Specifically, the motor cable is connected to the electrical control box 22 through the opening 13.

[0122] Of course, in some other embodiments, when the accommodating cavity 10 is also provided with a temperature and humidity sensor, an electric heater and a water pump, etc., the cables of the temperature and humidity sensor, the electric heater and the water pump, etc. can also be connected to the electrical control box 22 through the opening 13. This embodiment does not limit this.

[0123] When the cable 221 includes a transition section 2211 exposed outside the control box 22 and the housing cavity 10, the transition section 2211 can be designed as a cable 221 that can be connected by plugging and unplugging. With this configuration, since the transition section 2211 is located outside the control box 22 and the housing cavity 10, it is convenient to plug and unplug the cable 221.

[0124] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The indoor unit 100 of the air conditioner includes: a housing 1, a motor 21, an electrical control box 22, a cable 221, and a cover 23. The housing 1 has a cavity 10 inside, and the housing 1 is provided with an air outlet 12 and an air inlet 11 that communicate with the cavity 10. The air inlet 11 is located on the rear side of the housing 1, and the air outlet 12 is arranged opposite to the air inlet 11.

[0125] See Figure 4 , Figure 5 , Figure 6 and Figure 7The motor 21 is located in the accommodating cavity 10, the electric control box 22 is arranged on the casing 1 and located outside the accommodating cavity 10, the casing 1 is further provided with an opening 13 communicating with the accommodating cavity 10, and the cable 221 is connected between the motor 21 and the electric control box 22 through the opening 13. The cable 221 includes a transition section 2211 exposed outside the accommodating cavity 10 and the electric control box 22, the cover 23 and the electric control box 22 form a protection cavity 20, and at least part of the transition section 2211 is located in the protection cavity 20.

[0126] In the embodiment, by arranging the electric control box 22 on the casing 1 and outside the accommodating cavity 10, compared with the mode of arranging the electric control box 22 in the accommodating cavity 10 of the casing 1, on the one hand, the maintenance of the electric control box 22 becomes simpler, and on the other hand, no space needs to be reserved in the accommodating cavity 10 for placing the electric control box 22, so that the casing 1 can be designed to be relatively small.

[0127] In addition, by covering at least part of the transition section 2211 by the cover 23, the cover 23 can protect the transition section 2211, so that the environment of the transition section 2211 of the cable 221 is relatively safe, on the one hand, the safety hidden danger such as fire or electric shock of the cable 221 can be avoided, and on the other hand, the air conditioner indoor unit 100 will also have no messy cable 221 from the appearance, so that the wiring of the air conditioner indoor unit 100 is more neat and the appearance performance is better.

[0128] In some embodiments, referring to Figure 5 and Figure 6 , the cover 23 is used for covering at least part of the transition section 2211.

[0129] By covering at least part of the transition section 2211 by the cover 23, the cover 23 can protect the transition section 2211, so that the environment of the transition section 2211 of the cable 221 is relatively safe, on the one hand, the safety hidden danger such as fire or electric shock of the cable 221 can be avoided, and on the other hand, the air conditioner indoor unit 100 will also have no messy cable 221 from the appearance, so that the wiring of the air conditioner indoor unit 100 is more neat and the appearance performance is better.

[0130] In some embodiments, referring to Figure 4 , the opening 13 is a maintenance opening for maintaining the motor 21.

[0131] By making the opening 13 a maintenance opening for maintaining the motor 21, the opening 13 can be used not only for routing the cable 221, but also for maintaining the motor 21 through the opening 13. In other words, the cable 221 routing and the motor 21 maintenance can share one opening 13, so that there is no need to open a separate opening 13 on the casing 1 for routing the cable 221, but directly use the maintenance opening.

[0132] In this way, on the one hand, the manufacturing cost of opening a separate opening 13 on the casing 1 for routing the cable 221 can be reduced, and on the other hand, the mechanical strength of the casing 1 can be avoided from being affected by opening a separate opening 13 on the casing 1 for routing the cable 221, so that the casing 1 is more solid and durable.

[0133] In other embodiments, the opening 13 for routing the cable 221 and the maintenance opening for maintaining the motor 21 can also be two separate openings, which are not limited in this embodiment.

[0134] The shape of the opening 13 can be circular, square, or other irregular shapes, and the shape of the opening 13 is not limited in this embodiment.

[0135] Considering that one of the important functions of the opening 13 is to route the cable 221, in order to avoid the situation that the edge of the opening 13 cuts the cable 221, in some embodiments, referring to Figure 4 and Figure 8 , Figure 8 is Figure 4 the structure diagram of part of the structure of the casing 1, the edge of the opening 13 is provided as a dead edge.

[0136] By providing the edge of the opening 13 as a dead edge, the edge of the opening 13 can be relatively blunt and not too sharp, so that the situation that the edge of the opening 13 cuts the cable 221 can be avoided, and the situation that the edge of the opening 13 cuts the personnel can also be avoided.

[0137] The implementation of the dead edge has many ways, in one possible implementation, the edge of the opening 13 can be provided as a dead edge by bending a flange on the edge of the opening 13, of course, the edge of the opening 13 can also be provided as a dead edge by other ways, which are not limited in this embodiment.

[0138] In some embodiments, referring to Figure 4 , Figure 5 and Figure 6 , the control box 22 covers part of the opening 13, and the cable 221 is connected between the motor 21 and the control box 22 through the remaining opening 13.

[0139] By covering part of the opening 13 with the electric control box 22, the electric control box 22 can also shield the opening 13 when the electric control box 22 is installed on the casing 1, so that a structure specially designed for shielding the opening 13 is not needed, the electric control box 22 can serve multiple purposes, the structure of the air conditioner indoor unit 100 can be simplified, the number of parts of the air conditioner indoor unit 100 can be reduced, and the cost of the air conditioner indoor unit 100 can be lowered.

[0140] In some embodiments, referring to Figure 3 , Figure 5 and Figure 6 , the covering cover 23 covers the remaining opening 13.

[0141] By covering the remaining opening 13 with the covering cover 23, when the electric control box 22 and the covering cover 23 are both installed on the casing 1, the entire opening 13 can be completely covered by the electric control box 22 and the covering cover 23. In this way, on the one hand, the situation that dust and the like enters the accommodation cavity 10 through the opening 13 can be avoided, the operating environment of the evaporator 2 and the motor 21 in the accommodation cavity 10 is cleaner, and the evaporator 2 and the motor 21 are less likely to be contaminated by dust. At the same time, from the appearance, the air conditioner indoor unit 100 can be made more neat and beautiful.

[0142] Of course, in other embodiments, part of the opening 13 can not be covered, which is not limited in the present embodiment.

[0143] In some embodiments, referring to Figure 3 and Figure 5 , the covering cover 23 is detachably arranged on the casing 1 or the electric control box 22.

[0144] By detachably arranging the covering cover 23 on the casing 1 or the electric control box 22, when the cable 221 covered in the covering cover 23 needs to be maintained due to an abnormality during the operation of the air conditioner indoor unit 100, the covering cover 23 can be detached to expose the cable 221 for maintenance. After the maintenance of the cable 221 is completed, the covering cover 23 can be reinstalled.

[0145] It can be seen that by detachably arranging the covering cover 23 on the casing 1 or the electric control box 22, the maintenance of the cable 221 can be made very convenient.

[0146] Among the above implementation manners of the covering cover 23, in one possible implementation manner, referring to Figure 4 , Figure 9 and Figure 10 , Figure 9 is a partial enlarged view of the air conditioner indoor unit 100 at the A position in Figure 4 , Figure 10 is a partial enlarged view of the air conditioner indoor unit 100 at the A position in Figure 4A structural schematic view of the covering cover 23, the covering cover 23 comprises a cover body part 231, the cover body part 231 and the electric control box 22 enclose a protection cavity 20, and at least part of the transition section 2211 is located in the protection cavity 20, so as to cover at least part of the transition section 2211.

[0147] By enclosing the cover body part 231 and the electric control box 22 to form the protection cavity 20, and locating at least part of the transition section 2211 in the protection cavity 20, the cover body part 231 and the electric control box 22 can jointly protect the transition section 2211 of the cable 221, so that the running environment of the cable 221 is safer.

[0148] In addition, since the protection cavity 20 is formed by enclosing the cover body part 231 and the electric control box 22, compared with the mode that the cover body part 231 itself forms the entire protection cavity 20, the electric control box 22 can be used as part of the structure for enclosing the protection cavity 20, so that the material of the cover body part 231 can be saved to some extent.

[0149] In some embodiments, referring to Figure 9 and Figure 10 , the covering cover 23 further comprises a first insertion part 232 and a first locking part 233, the first insertion part 232 is arranged on the cover body part 231, the first insertion part 232 is arranged on the cover body part 231, the first insertion part 232 is arranged on the cover body part 231, and the first insertion part 232 is arranged on the cover body part 231.

[0150] Since the first insertion part 232 is arranged on the cover body part 231, and the first insertion part 232 is arranged on the cover body part 231, when the covering cover 23 needs to be installed on the cabinet 1, first, the first insertion part 232 can be inserted into the first insertion part 232, and after the first insertion part 232 is inserted into the first insertion part 232, the covering cover 23 can be preliminarily installed on the cabinet 1.

[0151] Then, since the first locking part 233 is arranged on the cover body part 231, the first locking part 233 can be detachably locked on the cabinet 1, and thus the covering cover 23 can be detachably arranged on the cabinet 1.

[0152] It can be seen that by arranging the first insertion part 232 on the cover body part 231 and the first insertion part 232 on the cover body part 231, the first insertion part 232 and the first insertion part 232 can be used for positioning the covering cover 23 on the cabinet 1, so that the installation precision of the covering cover 23 on the cabinet 1 is higher.

[0153] After the first insertion part 232 is inserted into the first to-be-inserted part 14, the cover body part 231 is locked to the shell 1 through the first locking part 233. This mounting mode can ensure installation precision, and can also simplify the installation difficulty to a certain extent and reduce the installation steps.

[0154] In some embodiments, referring to Figure 10 The first locking part 233 can be a sheet metal piece which can be detachably locked to the shell 1 through screws.

[0155] In some embodiments, referring to Figure 3 and Figure 10 The cover body part 231 comprises a bottom wall 2311 and a surrounding wall 2312. The bottom wall 2311 is spaced apart from the electric control box 22. The surrounding wall 2312 is arranged on part of the circumferential edge of the bottom wall 2311 along the circumferential direction of the bottom wall 2311. One end of the surrounding wall 2312 away from the bottom wall 2311 faces the electric control box 22, so that the bottom wall 2311, the surrounding wall 2312 and the electric control box 22 form a protection cavity 20. The other end of the bottom wall 2311 not provided with the surrounding wall 2312 faces the opening 13.

[0156] Since the bottom wall 2311 is spaced apart from the electric control box 22, the surrounding wall 2312 is arranged on part of the circumferential edge of the bottom wall 2311 along the circumferential direction of the bottom wall 2311, and one end of the surrounding wall 2312 away from the bottom wall 2311 faces the electric control box 22, the bottom wall 2311, the surrounding wall 2312 and the electric control box 22 can form a protection cavity 20. It can be seen that the protection cavity 20 can be formed by a very simple structure, so that the structure of the cover body part 231 can be simplified to a certain extent, and the cost of the cover body part 231 can be reduced.

[0157] In addition, by making the other end of the bottom wall 2311 not provided with the surrounding wall 2312 face the opening 13, the protection cavity 20 can communicate with the accommodation cavity 10 through the opening 13. This provides structural guarantee for the cable 221 in the protection cavity 20 to enter the accommodation cavity 10 through the opening 13, and also makes the cable 221 enter the accommodation cavity 10 as straight as possible.

[0158] In some embodiments, referring to Figure 4 and Figure 10 The other end of the bottom wall 2311 not provided with the surrounding wall 2312 abuts against the shell 1.

[0159] By making the other end of the bottom wall 2311 not provided with the surrounding wall 2312 abut against the shell 1, the sealing between the other end of the bottom wall 2311 not provided with the surrounding wall 2312 and the shell 1 can be better, and the sealing of the protection cavity 20 can be improved to a certain extent, so that the situation that the dust in the outside enters the protection cavity 20 can be avoided or reduced.

[0160] In some embodiments, referring to Figure 3 and Figure 10 the two opposite ends of the surrounding wall 2312 along the circumferential direction of the surrounding wall 2312 also abut against the shell 1.

[0161] By making the two opposite ends of the surrounding wall 2312 along the circumferential direction of the surrounding wall 2312 also abut against the shell 1, the sealing between the two opposite ends of the surrounding wall 2312 along the circumferential direction of the surrounding wall 2312 and the shell 1 can also be better, thereby further improving the sealing of the protection cavity 20 to a certain extent, so as to further avoid or reduce the situation that dust from the outside enters the protection cavity 20.

[0162] In some embodiments, referring to Figure 10 the first insertion part 232 and the first locking part 233 are respectively arranged at the two opposite ends of the surrounding wall 2312 along the circumferential direction of the surrounding wall 2312.

[0163] By making the first insertion part 232 and the first locking part 233 respectively arranged at the two opposite ends of the surrounding wall 2312 along the circumferential direction of the surrounding wall 2312, the two opposite ends of the surrounding wall 2312 along the circumferential direction of the surrounding wall 2312 can be fixed on the shell 1 under the action of the first insertion part 232 and the first locking part 233, that is, under the action of the first insertion part 232 and the first locking part 233, the two free ends of the covering cover 23 can be fixed, and in this way, the entire covering cover 23 can be more stably and reliably installed on the shell 1.

[0164] Among them, the implementation mode of the above-mentioned first insertion part 232 has multiple, in one of the possible implementation modes, referring to Figure 4 , Figure 9 and Figure 10 the first insertion part 232 is a first insertion sheet, the first insertion sheet is inserted into the first insertion part 232 along the direction parallel to the surface of the first shell (the Z-axis direction in Figure 9 ), and the surface of the first shell refers to the surface of the shell 1 at the first insertion part 232.

[0165] In the case that the first insertion part 232 is a first insertion sheet, by making the first insertion sheet inserted into the first insertion part 232 along the direction parallel to the surface of the first shell (the Z-axis direction in Figure 9 ), the entire first insertion part 232 can be arranged close to the surface of the shell 1, without penetrating into the insertion cavity 10 of the shell 1, so that the first insertion part 232 can not occupy or less occupy the space of the insertion cavity 10, thereby avoiding the mutual interference between the first insertion part 232 and the motor 21 in the insertion cavity 10 to a certain extent.

[0166] The first insertion part 14 can be a socket formed by stamping or other means. In this embodiment, the first insertion part 14 is not limited.

[0167] In some embodiments, see Figure 1 , Figure 11 and Figure 12 , Figure 11 yes Figure 1 A schematic diagram of the structure of the central control box 22. Figure 12 yes Figure 11 An exploded view of the electrical control box 22 shows that the electrical control box 22 includes a box body 223 and a control component 222. The box body 223 is detachably mounted on the housing 1, the control component 222 is mounted inside the box body 223, and the cable 221 is connected between the motor 21 and the control component 222 through the opening 13.

[0168] Since the control component 222 is located inside the housing 223, the housing 223 can protect the control component 222, making the operation of the control component 222 safer.

[0169] In addition, by making the box 223 detachably mounted on the housing 1, when the electrical control box 22 needs to be maintained, the box 223 can be removed from the housing 1 for maintenance, which is very convenient.

[0170] The shape of the box 223 can be a cuboid, a cube, or other possible shapes, and this embodiment does not limit this.

[0171] The control component 222 mentioned above can be a main control board or other components that can control the motor 21. This embodiment does not limit the control component 222.

[0172] In some embodiments, see Figure 13 and Figure 14 , Figure 13 yes Figure 1 Another exploded view of the indoor unit 100 of the air conditioner. Figure 14 yes Figure 13 A partial enlarged view at position B shows that the box body 223 is provided with a second insertion part 2231, and the housing 1 is provided with a second insertion part 15 that matches the second insertion part 2231. The second insertion part 2231 is arranged in a direction parallel to the surface of the second housing. Figure 14 The second housing surface is the surface of the housing 1 at the second housing 15 (in the X-axis direction).

[0173] By providing a second insertion part 2231 on the housing 223 and a second insertion part 15 on the casing 1 that matches the second insertion part 2231, when the second insertion part 2231 is pluggably inserted into the second insertion part 15, the interaction between the second insertion part 2231 and the second insertion part 15 can, on the one hand, achieve a pre-positioning function, thereby increasing the installation accuracy of the housing 223 when it is installed on the casing 1. On the other hand, since the pluggable method is simple to operate, the process of installing the housing 223 onto the casing 1 can be simplified to a certain extent.

[0174] Furthermore, by making the second insertion portion 2231 move in a direction parallel to the surface of the second housing ( Figure 14 The second insertion part 2231 is pluggably inserted into the second insertion part 15 in the X-axis direction. This allows the second insertion part 2231 to be positioned close to the surface of the housing 1 when it is inserted into the second insertion part 15, without penetrating the deeper insertion cavity 10 of the housing 1. This ensures that the second insertion part 2231 does not occupy or occupies little space in the cavity 10, thereby avoiding interference between the second insertion part 2231 and the motor 21 and other components in the cavity 10 to a certain extent.

[0175] The number of the second insertion portions 2231 can be as follows: Figure 13 The two shown are examples of the second insertion part 2231. Of course, the number of the second insertion part 2231 can also be one or three, etc., and this embodiment does not limit this.

[0176] The structure of the second insertion part 15 described above may be the same as or similar to the structure of the first insertion part 14 described above, and this embodiment does not limit it in this regard.

[0177] In some embodiments, see Figure 13 and Figure 14 A locking piece 16 is provided on the housing 1, and the locking piece 16 abuts against the end of the box 223 away from the second insertion part 2231. Figure 13 The right end of the middle box 223), and the surface of the locking piece 16 is aligned with the insertion direction of the second insertion part 2231 ( Figure 13 (In the Y-axis direction) perpendicular, the locking piece 16 is detachably locked to the housing 223.

[0178] By making the locking piece 16 abut against the end of the housing 223 away from the second insertion part 2231, and by making the surface of the locking piece 16 aligned with the insertion direction of the second insertion part 2231 ( Figure 13The verticality of the second insertion part 2231 (the direction along the Y-axis) can limit the box body 223 between the second insertion part 15 and the locking piece 16. In this way, the second insertion part 2231 can be prevented from being abnormally slid out of the second insertion part 15 in a direction away from the insertion direction of the second insertion part 2231 under the limiting action of the locking piece 16. Thus, the box body 223 can be more stably installed in the cabinet 1.

[0179] The locking piece 16 can be detachably locked to the box body 223 by a screw, and can also be detachably locked to the box body 223 by other means, which is not limited in the embodiment.

[0180] Figure 15 is a structural schematic diagram of an air conditioning system 1000 provided by an embodiment of the present application.
