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.

[0047] 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 direct connection, or an indirect connection 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 utility model can be understood according to specific circumstances.

[0048] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0049] In the present application, the air conditioner performs a refrigeration cycle or a heating cycle of the air conditioner through a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle and the heating cycle include a series of processes such as compression, condensation, expansion and evaporation, and provide cooling or heat to the indoor space through the heat absorption or heat release of the refrigerant to adjust the temperature of the indoor space.

[0050] 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 of the refrigerant is released to the surrounding environment through the condensation process.

[0051] The expansion valve expands the liquid refrigerant flowing out of the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve into a low-temperature, low-pressure refrigerant gas, and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling 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.

[0052] The outdoor unit of the air conditioner refers to a part 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 the expansion valve may be provided in the indoor unit or the outdoor unit.

[0053] 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.

[0054] The air conditioner indoor unit has an air inlet and an air outlet. A protective net is usually provided at the air outlet of the air conditioner indoor unit to prevent a user from putting his hand into the interior of the air conditioner indoor unit and causing a safety accident.

[0055] See also Figure 1 - Fig.16 As shown, the embodiment of the present application provides an air conditioner indoor unit, including a casing 5, a base 1, a volute 2, a volute tongue 3 and a protective net 4, an air inlet and a first air outlet 51 are formed on the casing 5, and an air guide plate 52 is installed at the first air outlet 51; the base 1 is arranged in the casing 5; the volute 2 is arranged in the casing 5 and fixed on the base 1; the volute tongue 3 is arranged in the casing 5, the volute tongue 3 is connected to one side of the volute 2, and an air outlet duct 32 connected to the first air outlet 51 is formed between the volute tongue 3 and the volute 2 to guide the airflow entering the air inlet ( Figure 5 The arrow in the figure indicates the airflow direction) is guided to the first air outlet 51, and the air outlet duct 32 has a second air outlet 321; the protective net 4 is arranged in the air outlet duct 32 to block the second air outlet 321. The protective net 4 includes a protective net body 41 and a mounting bracket 42, and the mounting bracket 42 is connected to the protective net body 41.

[0056] The first connection part 20 is formed on one side of the volute 2 facing the air outlet duct 32, and the second connection part 30 is formed on one side of the volute tongue 3 facing the air outlet duct 32. One of the first connection part 20 and the second connection part 30 is a card slot 21, and the other is a first fastener 31. The mounting bracket 42 is a mounting carrier of the protective net body 41. The mounting bracket 42 has an abutting part 421 for abutting with the volute tongue 3 or the volute 2 and a card slot 21. The second fastener 423 is provided on one end of the mounting bracket 42 close to the abutting part 421.

[0057] The clamping portion 422 is rotatably installed in the clamping slot 21 and is detachably connected to the clamping slot 21. The mounting bracket 42 is rotated in the direction close to the first fastener 31, so that the second fastener 423 is connected to the first fastener 31, and the abutting portion 421 abuts on the volute tongue 3 or the volute 2 where the first fastener 31 is located, so as to limit the rotation of the mounting bracket 42, so that the protective net body 41 is fixed in the air outlet duct 32, and prevent the user from reaching into the air outlet duct 32 to touch the air outlet power components and cause safety accidents.

[0058] The present application forms an air outlet duct 32 through the volute 2 and the volute tongue 3 to deliver cold air or hot air to the indoor space to adjust the temperature of the indoor space. An abutment portion 421, a clamping portion 422 and a second fastener 423 are provided on the mounting bracket 42 of the protective net 4, and the clamping portion 422 is clamped in the clamping slot 21, and the clamping portion 422 is rotatable in the clamping slot 21, so that the mounting bracket 42 can rotate, which facilitates the installation of the mounting bracket 42. After the clamping part 422 is clamped in the clamping slot 21, the mounting bracket 42 is rotated until the second fastener 423 is connected to the first fastener 31, and the abutting part 421 abuts on the volute tongue 3 or the volute 2 where the first fastener 31 is located. The connection between the second fastener 423 and the first fastener 31 and the abutment between the abutting part 421 and the volute tongue 3 or the volute 2 can limit the continued rotation of the mounting bracket 42, so that the protective net body 41 is fixed in the air outlet duct 32, plays a protective role, and can realize the rapid installation of the protective net 4. When disassembling the protective net 4, the connection between the first fastener 31 and the second fastener 423 is released, and the mounting bracket 42 is rotated in the opposite direction, so that the abutting part 421 can be separated from the volute tongue 3, and the restriction on the mounting bracket 42 is released. Then, the clamping part 422 is pulled out of the clamping slot 21 by force, so that the clamping part 422 is separated from the clamping slot 21, and the protective net 4 can be disassembled without the help of other tools. Therefore, the present application can improve the efficiency of disassembling and assembling the protection net 4. In addition, the protection net 4 is installed at the second air outlet 321 of the air outlet duct 32 to reduce wind resistance.

[0059] See also Figure 4 , Figure 8 and Fig. 9 In some embodiments, a slot 21 is formed on one side of the volute 2 facing the air outlet duct 32, and a first fastener 31 is formed on one side of the volute tongue 3 facing the air outlet duct 32. When the second fastener 423 on the mounting bracket 42 is connected to the first fastener 31, the abutting portion 421 of the mounting bracket 42 abuts against the volute tongue 3, and the clamping portion 422 of the mounting bracket 42 is clamped in the slot 21.

[0060] See also Figure 5 and Figure 7 As shown, in some embodiments, the slot 21 is a U-shaped slot, the slot opening of the slot 21 is arranged toward the air outlet duct 32 , and the slot wall shape of the slot 21 is roughly arc-shaped, which facilitates the rotation of the clamping portion 422 in the slot 21 .

[0061] See also Figure 6 As shown, in some embodiments, the first fastener 31 has an inclined surface 311, and a clamping groove 312 is formed between the inclined surface 311 and a side of the volute tongue 3 or the volute 2 facing the air outlet duct 32. The clamping groove 312 is used to clamp the second fastener 423. The notch of the clamping groove 312 is arranged toward the inner side of the volute 2. The first fastener 31 is a block structure. The first fastener 31 is integrally formed with the volute tongue 3 or the volute 2 where it is located.

[0062] See also Figure 3 As shown, multiple protective nets 4 can be provided, and the multiple protective nets 4 cover the second air outlet 321 of the air outlet duct 32 along the length direction of the base 1 to protect the air outlet duct 32. The structures of the protective nets 4 are basically the same, and the arrangement methods of the protective nets 4 are basically the same.

[0063] See also Fig.12 - Fig.15 As shown, in some embodiments, one side of the abutting portion 421 of the mounting bracket 42 is inclined to form an abutting surface 4211 for abutting against the volute tongue 3 or the volute 2. The abutting portion 421 abuts against the volute tongue 3 as an example for description. The abutting surface 4211 is in surface contact with the volute tongue 3, which can improve the stability of the abutment between the mounting bracket 42 and the volute tongue 3, thereby improving the installation stability of the protective net 4. The inclination of the abutting surface 4211 is consistent with the inclination of the side of the volute tongue 3 facing the air outlet duct 32, so that the abutting surface 4211 can fit on the side of the volute tongue 3 facing the air outlet duct 32.

[0064] See also Figure 6 and Fig. 9 In some embodiments, the second fastener 423 includes a fixing portion 4231 and a clamping portion 4232. The fixing portion 4231 is fixed to the mounting bracket 42. The clamping portion 4232 is connected to the fixing portion 4231. The shape of the clamping portion 4232 matches the clamping slot 312 so as to be clamped in the clamping slot 312. The fixing portion 4231 and the clamping portion 4232 are integrally formed. In order to facilitate the clamping portion 4232 to enter and exit the clamping slot 312, one end of the clamping portion 4232 not connected to the fixing portion 4231 is set to be hook-shaped. Taking the first fastener 31 provided on the volute tongue 3 as an example, the end of the clamping portion 4232 not connected to the fixing portion 4231 has two intersecting surfaces, one surface cooperates with the inclined surface 311 of the first fastener 31, and the other surface cooperates with a surface of the volute tongue 3 facing the air outlet duct 32, and the angle between the two surfaces is adapted to the size of the clamping slot 312.

[0065] See also Figure 7In some embodiments, the clamping portion 422 is substantially cylindrical, and the diameter of the clamping portion 422 is consistent with the diameter of the groove wall of the clamping groove 21, so that the clamping portion 422 can be clamped in the clamping groove with an arc-shaped groove wall, and the clamping portion 422 cannot be disengaged from the clamping groove 21 without using external force. The contact portion between the clamping portion 422 and the groove bottom of the clamping groove 21 is set as a plane, so that when the mounting bracket 42 is fixed between the volute 2 and the volute tongue 3, the plane portion of the clamping portion 422 abuts against the plane portion of the groove bottom of the clamping groove 21, making the clamping portion 422 more stable in the clamping groove 21.

[0066] See also Fig.10 and Fig.11 As shown, in order to facilitate the installation of the protection net 4 and improve the stability of the installation of the protection net 4, in some embodiments, a mounting bracket 42 is provided at each end in the length direction of the protection net body 41. In order to improve the versatility of the mounting bracket 42, the mounting brackets 42 at both ends of the protection net body 41 have the same structure.

[0067] See also Fig.12 - Fig.15 As shown, in some embodiments, the mounting bracket 42 includes a connecting member 424 and a plurality of mounting portions 425, wherein the plurality of mounting portions 425 are arranged at intervals on the connecting member 424, and the end of the mounting portion 425 is provided with a mounting hole 4251 for connecting with the protective net body 41. The abutting portion 421 and the clamping portion 422 are respectively fixed at the two ends of the connecting member 424, and the second fastener 423 is fixed on one of the mounting portions 425. The mounting portion 425 is cylindrical, and the mounting hole 4251 is a circular hole. Both ends of the first connecting strip 411 in the protective net body 41 can be installed in the mounting hole 4251, so that the mounting brackets 42 at both ends can be used interchangeably.

[0068] In some embodiments, a mounting hole 4251 for connecting with the protective net body 41 is provided at the end of the partial mounting portion 425, and the end of the partial mounting portion 425 is a closed end 4252. The mounting hole 4251 is used for inserting a portion of the protective net body 41, and the closed end 4252 is used to abut against a portion of the protective net body 41, so that the mounting bracket 42 cannot be replaced by 180 degrees for installation, and the mounting bracket 42 is prevented from being installed in the wrong direction on the protective net body 41. This arrangement can make the mounting directions of the mounting brackets 42 at both ends of the protective net body 41 consistent, so that after the mounting brackets 42 at both ends are installed, the second fasteners 423 correspond to the positions of the first fasteners 31 respectively, and the clamping portions 422 correspond to the positions of the clamping slots 21 respectively, so as to facilitate the connection and fixation of the mounting bracket 42 with the volute 2 and the volute tongue 3, and facilitate the installation and fixation of the protective net 4 in the air outlet duct 32.

[0069] See also Fig.12As shown, in some embodiments, the mounting portion 425 is disposed through the connecting member 424, and both ends of the mounting portion 425 are provided with mounting holes 4251 or are both closed ends 4252, so that both left and right sides of the mounting bracket 42 can be connected to the protective net body 41, so that the mounting bracket 42 can be turned left and right for use, so that the mounting bracket 42 can be quickly installed on the protective net body 41. When both ends of the mounting portion 425 are provided with mounting holes 4251, the mounting holes 4251 penetrate the mounting portion 425 along the axial direction of the mounting portion 425.

[0070] See also Fig.12 As shown, in some embodiments, the second fastener 423 includes a clamping portion 4232 and two fixing portions 4231, the two fixing portions 4231 are respectively fixed to the mounting portions 425 on both sides of the connecting member 424, the clamping portion 4232 is connected between the two fixing portions 4231, and the clamping portion 4232 is connected to the first fastener 31. The clamping portion 4232 is connected to the two fixing portions 4231 to form a U-shaped structure. This arrangement makes the structure of the second fastener 423 stable, and the clamping portion 4232 of the second fastener 423 can be connected to a plurality of first fasteners 31 spaced apart on the volute tongue 3 or the volute 2, thereby ensuring the connection stability between the second fastener 423 and the first fastener 31, thereby ensuring the installation stability of the mounting bracket 42. For example, a plurality of first fasteners 31 are disposed at intervals on the volute tongue 3 , and the inclined surfaces 311 of the first fasteners 31 respectively form a clamping groove 312 with a surface of the volute tongue 3 facing the air outlet duct 32 , and the clamping portions 4232 are clamped in the plurality of clamping grooves 312 .

[0071] See also Fig.12 - Fig.15 In some embodiments, the end of the connecting member 424 close to the volute 2 has a bent portion 426, the bent portion 426 is bent toward the inner side of the volute 2, and the clamping portion 422 is fixed on the bent portion 426. The bent portion 426 serves to connect the clamping portion 422 with the connecting member 424 of the mounting bracket 42, and the setting of the bent portion 426 also enables the mounting bracket 42 to rotate smoothly in the air outlet duct 32, avoiding mutual interference between the mounting bracket 42 and the volute 2 when the mounting bracket 42 is rotated to make the clamping portion 422 rotate in the clamping slot 21. In some embodiments, the bent portion 426 is arc-shaped.

[0072] See also Fig.16As shown, in some embodiments, the protective net body 41 includes a plurality of first connecting strips 411 and at least one second connecting strip 412, wherein the plurality of first connecting strips 411 are arranged in parallel and at intervals, and the ends of the first connecting strips 411 are inserted into the mounting holes 4251 or abut against the closed ends 4252; the second connecting strips 412 vertically connect the first connecting strips 411. The length of the first connecting strip 411 that can be inserted into the mounting holes 4251 is greater than the length of the first connecting strip 411 abutting against the closed ends 4252, so that the first connecting strip 411 that needs to abut against the closed ends 4252 cannot be inserted into the mounting holes 4251, and the first connecting strip 411 that needs to be inserted into the mounting holes 4251 cannot abut against the closed ends 4252. When the mounting bracket 42 is connected to the protective net body 41, the positions of the mounting holes 4251 and the closed ends 4252 need to be adjusted so that the mounting bracket 42 is smoothly connected to the protective net body 41, and the mounting bracket 42 is prevented from being installed in the wrong direction.

[0073] In some embodiments, when one end of the same first connecting strip 411 abuts the closed end 4252, the other end can be inserted into the mounting hole 4251; or the two ends of the first connecting strip 411 can be respectively inserted into the mounting holes 4251. On the mounting bracket 42, at least one end of the mounting portion 425 is set as the closed end 4252. In order to ensure the versatility of the mounting bracket 42 at both ends of the protection net body 41, when one end of the mounting portion 425 is the closed end 4252, the other end is provided with a mounting hole 4251, so that when the mounting bracket 42 is mounted on one end of the protection net body 41, the closed end 4252 abuts against one end of the first connecting strip 411, and when the mounting bracket 42 is mounted on the other end of the protection net body 41, the other end of the first connecting strip 411 is inserted into the connecting hole of the mounting portion 425, so as to avoid that both ends of the first connecting strip 411 abut against the closed end 4252, causing instability.

[0074] In some embodiments, a plurality of first connecting bars 411 are arranged parallel to each other, and the second connecting bars 412 are arranged perpendicular to the first connecting bars 411.
