When the operator disassembles or maintains the sensor 3, he can directly observe the status of the sensor 3 through the return air outlet 11, effectively reducing the difficulty of disassembly and maintenance of the sensor 3. The adjacent arrangement of the sensor 3 and the back panel 20 can reduce the connection length of the wires, making the interior of the shell 1 more regular and concise.

[0040] The air conditioner indoor unit may be, for example, a ducted air conditioner or a wall mounted air conditioner, but the present disclosure is not limited thereto.

[0041] The shell 1 may include an outer shell, the interior of the outer shell can be divided into a return air chamber and an outlet air chamber by a middle partition 10. A fan such as a centrifugal fan can be installed in the return air chamber to realize the return air function, and a heat exchanger such as an evaporator can be installed in the outlet air chamber to realize the regulation of the external temperature.

[0042] Among them, the return air chamber can be the space between the middle partition 10 and the return air outlet 11, with a fan installed inside, the electrical control box 2 is installed in the outer shell, the back panel 20 of the electrical control box 2 can form one side wall of the return air chamber, and the other side wall of the return air chamber can be formed by the side wall of the outer shell.

[0043] For example, the housing can be constructed as a rectangular housing, and a ventilation net can be provided at the air return port 11 of the rectangular housing. The housing can also be constructed in any other suitable shape, and the present disclosure is not limited thereto.

[0044] The type of the sensor 3 can be adaptively adjusted according to actual needs. For example, the sensor 3 can be a temperature sensor, a humidity sensor, or a temperature and humidity sensor, etc. The present disclosure is not limited thereto.

[0045] In some embodiments, for example, referring to Figure 1 and Figure 2 As shown, the sensor 3 can have a mounting portion 30, which is directly or indirectly connected to the middle partition 10, and the vertical projection of the return air inlet 11 toward the middle partition 10 at least covers the mounting portion 30, so that the operator can directly observe and contact the installation position of the sensor 3 through the return air inlet 11, which is more conducive to the disassembly and maintenance of the sensor 3. For example, when the mounting portion 30 is installed by threaded fasteners such as bolts, it is convenient to extend the disassembly and assembly tools from the return air inlet 11 to facilitate disassembly and assembly.

[0046] In some embodiments, for example, referring to Figures 3 to 7 As shown, the air conditioner indoor unit may further include a mating portion 4 connected to the mounting portion 30. The mating portion 4 may be integrally formed on the middle partition 10 to simplify the manufacturing process and reduce economic costs. Alternatively, the mating portion 4 may be detachably connected to the middle partition 10, for example, by bolts, to facilitate replacement and maintenance.

[0047] In some embodiments, for example, referring to Figures 1 to 7 As shown, the air conditioner indoor unit may further include a connecting plate 21, the mating portion 4 may be provided on the connecting plate 21, the connecting plate 21 may be detachably connected to the middle partition 10, for example, the connecting plate 21 may be connected to the middle partition 10 by bolts, wherein the connecting plate 21 may be detachably connected to the back plate 20, so as to facilitate replacement of the connecting plate 21 or removal of the connecting plate 21 when necessary. Alternatively, the connecting plate 21 and the back plate 20 may be constructed as one piece to reduce the processing flow. In this embodiment, the connecting plate 21 may be formed as a flange of the back plate 20 so that the back plate 20 may be connected to the middle partition 10 through the connecting plate 21, wherein the connecting plate 21 may fit the middle partition 10 to increase the contact area and ensure connection stability.

[0048] Optionally, the mating portion 4 may include a raised portion 40 projecting from the connecting plate 21 toward the return air outlet 11 and a first mounting hole 41 provided on the raised portion 40. The mounting portion 30 may include a second mounting hole 31. The first mounting hole 41 and the second mounting hole 31 may be connected by a fastener. A clearance space for the fastener is provided between the raised portion 40 and the middle partition 10. The fastener may be configured as a bolt, a latch, a claw, or the like. The clearance space between the raised portion 40 and the middle partition 10 is used to provide sufficient installation space for the fastener.

[0049] In which, the mounting portion 30 may include a mounting plate 300, the second mounting hole 31 is arranged on the mounting plate 300, the protrusion 40 may have a fitting surface 401 fitted with the mounting plate 300, and in the first direction X perpendicular to the middle partition 10, the distance between the fitting surface 401 and the middle partition 10 may be a, the thickness of the mounting plate 300 may be b, and the length of the fastener may be c, wherein a+b>c, for example 5mm≤a≤10mm, to provide sufficient space for the installation of the fastener.

[0050] The configurations of the first mounting hole 41 and the second mounting hole 31 can be adaptively adjusted based on actual needs. For example, the first mounting hole 41 can be configured as a threaded hole, and the second mounting hole 31 can be configured as a through hole. Alternatively, both the first mounting hole 41 and the second mounting hole 31 can be configured as threaded holes, and the fastener can be configured as a bolt. Alternatively, both the first mounting hole 41 and the second mounting hole 31 can be configured as through holes, and the fastener can be configured as a claw that passes through the second mounting hole 31 and the first mounting hole 41 in sequence and then engages within the clearance space. The present disclosure is not limited to this.

[0051] Optionally, the raised portion 40 may include multiple baffles 400, and the sensor 3 may be positioned between at least two of the baffles. For example, there may be two baffles 400, which may be arranged horizontally and opposite each other along the same direction as the middle partition 10 extends. The sensor 3 may be positioned between the two baffles 400, thereby ensuring proper positioning of the sensor 3. Furthermore, when the fastener is configured as a bolt, for example, the two baffles 400 can limit the sensor 3 during assembly and disassembly while the bolt is being tightened, preventing it from rotating and facilitating assembly and disassembly.

[0052] The number of baffles 400 can be adaptively adjusted according to the needs of actual conditions. For example, the number of baffles 400 can also be three, wherein two baffles 400 can be arranged relative to each other along the same horizontal direction as the extension direction of the middle partition 10, and the sensor 3 is located between the two baffles 400, and the other baffle 400 can be arranged on the side of the sensor 3 away from the mounting portion 30 to further achieve precise positioning of the first mounting hole 41 and the second mounting hole 31; the number of baffles 400 can also be four or more, for example, they can be arranged at circumferential intervals around the sensor 3, but the present disclosure is not limited to this.

[0053] The sensor 3 may have a gap with at least one baffle 400 , or may have a gap with both opposite baffles 400 , so as to facilitate assembly and disassembly of the sensor 3 and avoid friction between the sensor 3 and the two baffles 400 .

[0054] The width of the gap can be of any appropriate size. For example, the width of the gap is d, 0.2 mm ≤ d ≤ 1 mm. This disclosure does not make any specific limitation on this. Those skilled in the art can make adaptive adjustments according to actual needs.

[0055] In some embodiments, for example, referring to Figures 1 to 7 As shown, in the first direction X perpendicular to the middle partition 10, the width of the baffle 400 can be smaller than the width of the sensor 3 to avoid the situation where the width of the baffle 400 is too large and exceeds the sensor 3 when the sensor 3 is connected to the electrical control box 2 through a wire, causing friction between the wire and the baffle 400 and damaging the wire.

[0056] In some embodiments, for example, referring to Figures 1 to 4 As shown, the connecting plate 21, the matching portion 4 and the back plate 20 can be integrally formed stamped parts to reduce the processing flow and save economic costs.

[0057] According to the second aspect of the present disclosure, for example, referring to Figures 1 to 7 As shown, an electric control box 2 is provided for installation in an air conditioner indoor unit. The air conditioner indoor unit may include a housing 1 having a middle partition 10 and a return air vent 11 arranged opposite each other. The electric control box 2 may include a back panel 20 and a connecting plate 21 connected thereto. The back panel 20 is located between the return air vent 11 and the middle partition 10 and has a wire hole 200. The connecting plate 21 is used to install a sensor 3 capable of detecting temperature and / or humidity, so that the sensor 3 is connected to the middle partition 10 via the connecting plate 21 and is arranged adjacent to the back panel 20. The wire hole 200 is used to pass the wires of the sensor 3. By arranging the sensor 3 adjacent to the back panel 20, the extension length of the wires can be reduced, making the interior of the housing 1 more neat and concise, and reducing the difficulty for operators to inspect and maintain the sensor 3.

[0058] In some embodiments, for example, referring to Figures 1 to 7 As shown, the connecting plate 21 may be provided with a mating portion 4, which may include a raised portion 40 and a first mounting hole 41 provided on the raised portion 40. The first mounting hole 41 is connected to the second mounting hole 31 of the sensor 3 via a fastener. The raised portion 40 has a clearance space on the side facing the middle diaphragm 10 to allow for the fastener to pass through. For example, the fastener may be a bolt or a latch. The clearance space provides sufficient space for the fastener to be installed, preventing the fastener from contacting and damaging the middle diaphragm 10.

[0059] The matching manner of the first mounting hole 41, the second mounting hole 31 and the fastener can refer to the matching manner of the three in the air-conditioning indoor unit provided in the first aspect above, and will not be repeated in this disclosure.

[0060] In some embodiments, for example, referring to Figures 1 to 7 As shown, the raised portion 40 may have a plurality of baffles 400, and the sensor 3 is arranged between at least two baffles 400. The arrangement of the plurality of baffles 400 may refer to the arrangement of the baffles 400 in the air conditioner indoor unit provided in the first aspect above, and will not be repeated in this disclosure.

[0061] In some embodiments, for example, referring to Figures 1 to 7 As shown, the connecting plate 21, the matching portion 4 and the back plate 20 can be integrally formed stamped parts to reduce the processing flow and lower the economic cost.
