The first pivot portion 211 may cooperate with the first shaft hole 121, and the first pivot portion 211 may also cooperate with the motor shaft 231 of the motor 23. The way to drive the valve 21 to rotate is to drive the first pivot portion 211 to rotate through the motor 23. An installation space may be provided inside the motor cover 22, and the installation space may be used to install the motor 23. After the first pivot portion 211 and the motor 23 are assembled, they may be installed in the first shaft hole 121 through the mounting notch 122, and the motor cover 22 is fixed on the mounting boss 12.

[0045] It should be noted that the air conditioner indoor unit 100 may further include: an evaporator component 50 and a duct component 40. The evaporator component 50 can exchange heat with air to achieve cooling or heating of the air conditioner indoor unit 100. The duct component 40 can function to suck and supply air. The housing 10 can function to protect the evaporator component 50 and fix the switch door module 20. The housing 10 can be directly connected to the switch door module 20. The housing 10 can include: a front box body component 15, a rear box body component 16, a top cover 17, and a chassis 18. The front box body component 15 can include: an upper front box body part 151 and a lower front box body part 152. The rear box body component 16 can include: an upper rear box body part 161 and a lower rear box body part 162. The upper front box body part 151, the lower front box body part 152, the upper rear box body part 161, and the lower rear box body part 162 can all be connected together by snap connection. Of course, it can be understood that the connection method of the upper front box body part 151, the lower front box body part 152, the upper rear box body part 161, and the lower rear box body part 162 is not limited to this. For example, the connection method of the upper front box body part 151, the lower front box body part 152, the upper rear box body part 161, and the lower rear box body part 162 can be set as screw connection, etc.

[0046] Among them, the valve 21 can be installed at the ventilation opening 11 of the housing 10. The motor 23 can be installed in the installation space of the motor cover 22. The installation boss 12 is fixed to the motor cover 22. Thus, the switch door module 20 can be directly assembled on the housing 10. Specifically, the number of the ventilation openings 11 and the installation bosses 12 can both be set to two. The two ventilation openings 11 and the two installation bosses 12 can be respectively arranged on the left and right sides of the lower rear box body part 162. The installation boss 12 can be arranged on the upper side of the ventilation opening 11. Each ventilation opening 11 corresponds to an installation boss 12 on the upper side. It should be explained that the up and down directions are only described with reference to the attached drawings. The number of the valve 21 and the motor 23 corresponds to the number of the installation bosses 12. The number of the valve 21 and the motor 23 can both be set to two. Of course, it can be understood that the number of the ventilation openings 11 and the installation bosses 12 is not limited to this and can be set according to actual needs. For example, to produce a better air supply effect, the number of the ventilation openings 11 and the installation bosses 12 can be set to three, four, etc.

[0047] Specifically, when assembling the switch door module 20, the motor 23 can be first connected to the valve 21, and then the motor 23 is installed into the motor cover 22. After the switch door module 20 is assembled as a whole, the installation notch 122 installs the first pivot part 211 into the first shaft hole 121, and then the motor cover 22 is fixed on the installation boss 13. Specifically, the motor 23 can be fixed in the motor cover 22 by screws.

[0048] Thus, by providing the mounting boss 12 on the cabinet 10, the cabinet 10 and the switch door module 20 can cooperate with each other. After the switch door module 20 is assembled into one body, it can be directly assembled onto the cabinet 10, thereby making its structure simple, facilitating assembly, reducing the product cost, and further improving the reliability of the product.

[0049] In some embodiments of the present invention, as Figures 6 - 14 shown, the motor cover 22 may be provided with a first fixing portion 222 and a first snap portion 221, and the mounting boss 12 is provided with a second fixing portion 124 and a second snap portion 123. The second snap portion 123 and the first snap portion 221 can cooperate, and the fixing connector 24 can cooperate with the second fixing portion 124 and the first fixing portion 222 respectively to fix the mounting boss 12 and the connecting motor cover 22. Among them, the fixing connector 24 is provided in the form of a screw, and the second fixing portion 124 and the first fixing portion 222 are screwed together, which can fix the mounting boss 12 and the motor cover 22 in one position. During the assembly process, the second snap portion 123 and the first snap portion 221 can be snap-fitted first to position the installation position of the motor cover 22, and the second fixing portion 124 and the second snap portion 123 are aligned, and then the screws are respectively mated with the second fixing portion 124 and the first fixing portion 222. Such a setting can fixedly connect the motor cover 22 to the mounting boss 12, and the assembly process is simple, facilitating the assembly of the fixing connector 24.

[0050] In some embodiments of the present invention, the second snap portion 123 may be provided in the form of a limiting protrusion on the mounting boss 12, and the first snap portion 221 may be provided in the form of an elastic snap. The snap space 101 is located between the inner wall of the cabinet 10 and the limiting protrusion. A part of the elastic snap can extend into the snap space 101 and abut against the limiting protrusion. Among them, the shape of the first snap portion 221 can be set as the shape of a cuboid structure. A hook can be provided at one end of the cuboid structure. The shape of the second snap portion 123 can be set as the shape of a square protrusion. A part of the cuboid structure can extend into the snap space 101 and abut against the limiting protrusion through the hook. Of course, it can be understood that the shapes of the second snap portion 123 and the first snap portion 221 are not limited to this. For example, the second snap portion 123 can be a slot, and the first snap portion 221 can be a hook. Such a setting can strengthen the connection strength between the mounting boss 12 and the motor cover 22, and the elastic snap can improve the buffering strength of the motor cover 22, and can further improve the overall reliability of the air conditioner indoor unit 100.

[0051] In some embodiments of the present invention, a buckle guiding surface 125 may be provided on the limiting protrusion. The extending direction of the buckle guiding surface 125 may be inclined towards the inner wall of the housing 10. The first buckle portion 221 may cooperate with the buckle guiding surface 125, and the cooperation between the first buckle portion 221 and the buckle guiding surface 125 may guide a part of the first buckle portion 221 into the buckle space 101.

[0052] In a specific embodiment of the present invention, the number of the buckle guiding surfaces 125 may be set to two. Two buckle guiding surfaces 125 are correspondingly provided at both ends of the second buckle portion 123. The inclination angle of the inclined extension of the buckle guiding surface 125 may be set to 30°. Of course, it can be understood that the inclination angle of the inclined extension of the buckle guiding surface 125 is not limited to this. For example, the inclination angle of the inclined extension of the buckle guiding surface 125 may be set to 60°, 15°, etc. Such a setting can guide the first buckle portion 221 through the buckle guiding surface 125 when the second buckle portion 123 and the first buckle portion 221 are buckled, which can improve the assembly efficiency of the second buckle portion 123 and the first buckle portion 221 and avoid the phenomenon of too long assembly time caused by inaccurate buckling positions.

[0053] In some embodiments of the present invention, the first fixing portion 222 is provided in the form of a through hole, and the through hole may be provided on the motor cover 22. The second fixing portion 124 is provided in the form of a fixing column, and the fixing column may be provided on the mounting boss 12. The limiting rib 224 may be provided on the motor cover 22. The cooperation between the outer peripheral wall of the fixing column and the limiting rib 224 can limit the position of the fixing column. It should be noted that a through hole may be provided on the second fixing portion 124, and the size and shape of the through hole correspond to those of the first fixing portion 222, that is, the second fixing portion 124 and the first fixing portion 222 are coaxially arranged. Threads may be provided in the through hole of the second fixing portion 124. The fixing connecting piece 24 may pass through the second fixing portion 124 and be in threaded cooperation with the first fixing portion 222. The limiting rib 224 may be provided on the lower surface of the motor cover 22, and the number of the limiting ribs 224 may be set to multiple. The outer peripheral wall of the fixing column may cooperate with the multiple limiting ribs 224 to limit the fixing column. Such a setting can limit the positions of the second fixing portion 124 and the first fixing portion 222 when the second fixing portion 124 and the first fixing portion 222 are connected and cooperate, which is convenient for the connection and cooperation between the second fixing portion 124 and the first fixing portion 222. The setting of the limiting rib 224 can also enhance the connection strength between the mounting boss 12 and the motor cover 22, and further improve the overall reliability of the air conditioner indoor unit 100.

[0054] In some specific examples of the present invention, as Figure 10 shown, the limiting rib 224 may be formed in an arc shape so that the limiting rib 224 can completely fit on the outer surface of the fixing column to improve the limiting effect.

[0055] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, the first guide member 126 may be disposed on the mounting boss 12, and the second guide member 223 may be disposed on the motor cover 22. When the staff installs the door opening and closing module 20, the second guide member 223 cooperates with the first guide member 126 to guide the motor cover 22 at a fixed position. It should be noted that when the staff installs the door opening and closing module 20, that is, when assembling the motor cover 22 on the mounting boss 12, first move the second guide member 223 to a position corresponding to the first guide member 126, and then the second guide member 223 can move along the first guide member 126, so that the connection position of the mounting boss 12 and the connection position of the motor cover 22 correspond, that is, the position where the second buckle portion 123 can be buckled with the first buckle portion 221, and the assembly of the mounting boss 12 and the motor cover 22 is completed. Such a setting can, when assembling the mounting boss 12 and the motor cover 22, guide the mounting boss 12 and the motor cover 22 through the cooperation of the second guide member 223 and the first guide member 126, improve the assembly efficiency of the mounting boss 12 and the motor cover 22, and avoid the phenomenon of too long assembly time caused by inaccurate clamping positions.

[0056] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, a first guide member 126 may be disposed outside the first shaft hole 121, and the first guide member 126 is arranged in the form of an arc-shaped guide plate, and the second guide member 223 may be a guide convex column. It should be explained that when the staff installs the door opening and closing module 20, that is, when assembling the motor cover 22 on the mounting boss 12, first align the position of the guide convex column and the arc-shaped guide plate, and then make the guide convex column move along the arc of the guide plate, so that the connection position of the mounting boss 12 and the connection position of the motor cover 22 correspond, that is, the position where the second buckle portion 123 can be buckled with the first buckle portion 221, and the assembly of the mounting boss 12 and the motor cover 22 is completed. Such a setting can, when assembling the mounting boss 12 and the motor cover 22, guide the mounting boss 12 and the motor cover 22 through the cooperation of the guide convex column and the arc-shaped guide plate, improve the assembly efficiency of the mounting boss 12 and the motor cover 22, avoid the phenomenon of too long assembly time caused by inaccurate clamping positions, and setting the guide plate as an arc can reduce the resistance suffered by the guide convex column when moving along the arc-shaped guide plate, and further improve the assembly efficiency of the mounting boss 12 and the motor cover 22.

[0057] Of course, it can be understood that the second guiding member 2236 and the first guiding member 12 can also be formed into other structures. For example, the second guiding member 223 is formed into a protruding portion extending into the arc-shaped groove, and the first guiding member 126 is arranged in the form of an arc-shaped groove, as long as the cooperation between the second guiding member 2236 and the first guiding member 12 can guide the motor cover 22 to a fixed position.

[0058] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, the air conditioner indoor unit 100 may further include: a positioning boss 13. The inner wall of the housing 10 may be provided with a positioning boss 13, and a part of the motor cover 22 may be disposed between the mounting boss 12 and the positioning boss 13, so as to limit the degrees of freedom of the motor cover 22. In an example of the present invention, the number of the positioning bosses 13 may correspond to the number of the mounting bosses 12. The cooperation between the mounting boss 12 and the positioning boss 13 can fix the motor cover 22 at a position. Of course, it can be understood that the number of the positioning bosses 13 is not limited thereto, and the number of the positioning bosses 13 may also be set to three, four, etc. Such a setting can fix the degrees of freedom of movement of the motor cover 22 on the mounting boss 12, and avoid the situation that the air conditioner indoor unit 100 is damaged due to the movement of the motor cover 22 on the mounting boss 12.

[0059] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, the distance between the opposite side walls of the mounting notch 122 gradually increases in the direction away from the first shaft hole 121. It can also be interpreted that the opposite two side walls of the mounting notch 122 are not parallel, the extending directions of the opposite two side walls of the mounting notch 122 are both in the direction away from the first shaft hole 121, and the angles between the extending directions of the opposite two side walls of the mounting notch 122 and the direction away from the first shaft hole 121 are the same. In a specific embodiment of the present invention, the angle between the extending directions of the opposite two side walls of the mounting notch 122 and the direction away from the first shaft hole 121 may be set to 15°. Of course, it can be understood that the angle between the extending directions of the opposite two side walls of the mounting notch 122 and the direction away from the first shaft hole 121 is not limited thereto, and the angle between the extending directions of the opposite two side walls of the mounting notch 122 and the direction away from the first shaft hole 121 may also be set to 30°, 45°, etc. Such a setting can facilitate the installation of the first pivoting portion 211 in the first shaft hole 121, and limit a certain degree of freedom of the first pivoting portion 211 after successful installation, avoiding the situation that the overall structure of the air conditioner indoor unit 100 is unstable due to the movement of the first pivoting portion 211 in the mounting notch 122, and facilitating assembly, thereby improving the reliability of the product.

[0060] In some embodiments of the present invention, as Figure 5As shown, the side wall of the ventilation opening 11 opposite to the first shaft hole 121 can be a supporting plane 102. The second shaft hole 14 can be arranged on the supporting plane 102, and the second pivoting part 212 can be arranged on the valve 21. The second shaft hole 14 and the second pivoting part 212 can be rotationally matched.

[0061] In a specific embodiment of the present invention, the shape of the ventilation opening 11 can be set as a square, such as Figures 1 - 3 As shown, the side wall of the ventilation opening 11 opposite to the first shaft hole 121 is the lower wall of the ventilation opening 11. Of course, it can be understood that the upper and lower orientations are only described with reference to the attached drawings, and the orientation can be defined according to the actual use situation. For example, the side wall of the ventilation opening 11 opposite to the first shaft hole 121 is the rear wall of the ventilation hole, etc. Moreover, the shape of the ventilation opening 11 is not limited to this. For example, the shape of the ventilation opening 11 can be set as an oval, etc. Among them, the valve 21 can be arranged on the side wall of the ventilation opening 11 opposite to the first shaft hole 121. The valve 21 is rotationally matched with the second shaft hole 14 through the second pivoting part 212, and the opening or closing of the ventilation opening 11 can be realized. By setting the supporting plane 102, the valve can be supported, and both ends of the valve have support, which can improve the stability of the valve during the rotation process.

[0062] When the air conditioner indoor unit 100 is working, the ventilation opening 11 needs to be opened for air exchange. The first pivoting part 211 is matched with the motor shaft 231 of the motor 23. The motor 23 drives the first pivoting part 211 to rotate, which can drive the valve 21 to rotate. When the second pivoting part 212 rotates counterclockwise relative to the second shaft hole 14, the valve 21 opens and the ventilation opening 11 is open. When the second pivoting part 212 rotates clockwise relative to the second shaft hole 14, the valve 21 closes and the ventilation opening 11 is closed.

[0063] When installing the switch door module, first insert the second pivoting part 212 obliquely into the second shaft hole 123, and then press the installation notch 122 to install the first pivoting part 211 of the assembled switch door module 20 into the first shaft hole 121, and then fix the installation boss 12 to the motor cover 22.

[0066] In some embodiments of the present invention, as Figure 1 shown, a purification module 30 may be provided inside the housing 10. The ventilation opening 11 may be set as an indoor air inlet. When the valve 21 is in an open state, indoor air can enter the housing 10 through the ventilation opening 11. After the indoor air enters the housing 10, it can be purified by the purification module 30 and then discharged. In a specific embodiment of the present invention, the purification module 30 may include: a purification air fan and a purification air filter screen 103 assembly. Among them, the purification air fan may include: a fan assembly, an air outlet volute assembly, an air inlet volute assembly, etc. The purification air fan may be provided with a mounting plate, and the mounting plate can be used to assemble and fix the purification air fan to the rear box body part 16. Specifically, the mounting plate may be fixedly connected to the fan volute and the air outlet volute together. The mounting plate may be set as an integrally formed part with the fan volute and the air outlet volute. Of course, it can be understood that the connection manner between the mounting plate and the fan volute and the air outlet volute is not limited to this. For example, the mounting plate may be connected to the fan volute and the air outlet volute by a snap connection manner.

[0067] Furthermore, the air outlet volute assembly may be provided with air outlets, and the number of air outlets on the air outlet volute assembly may be set to multiple. The air inlet volute assembly may be provided with air inlets, and the number of air inlets on the air inlet volute assembly may be set to multiple. In a specific embodiment of the present invention, the number of air outlets on the air outlet volute assembly may be set to 2, and the number of air inlets on the air inlet volute assembly may be set to 2. A guiding and sealing structure may be provided on the air outlet, and the guiding and sealing structure cooperates with the fresh air outlet provided on the rear box body component 16.

[0068] The purified air blower can provide the power for the air flow in the purification module 30. The main filtering component is the purified air filter net 103 assembly. The purified air filter net 103 assembly may include: an intermediate filter, an air outlet filter, and an air inlet filter. The air inlet filter may be provided on the casing 10, and the air inlet filter may be set as the filter net 103. The air inlet filter plays a preliminary filtering role, and larger atmospheric pollutants can be preliminarily filtered by the filter net 103. For example Figure 1 As shown, the filter net 103 is slidably arranged on the casing 10. A filter net handle 111 may be provided on the filter net 103, and the filter net 103 can be pulled out of the casing 10 through the filter net 103 handle 111 to clean or replace the filter net 103.

[0069] The intermediate filter may be arranged between the air outlet filter and the air inlet filter. The intermediate filter plays a main filtering role. The filter may be set as an electrostatic chemical fiber filter, which can play a secondary filtering role. Smaller atmospheric pollutants can be adsorbed and filtered by it. The air outlet filter is arranged on the air outlet volute assembly, and the air outlet filter may be set as a filter net. The air outlet filter plays a tertiary filtering role, and larger atmospheric pollutants that have not been filtered by the air inlet filter can be filtered again by the filter net.

[0070] The casing 10 may be provided with a fresh air inlet and a purified air outlet 32. The purified air outlet 32 may be provided on the upper rear box body part 161. Thus, when the indoor air conditioner 100 performs the indoor circulation purification function, the valve 21 opens the ventilation opening 11, and indoor air enters the air inlet volute assembly through the ventilation opening 11, and completes three - stage filtering in sequence through the air inlet filter, the filter, and the air outlet filter, and then discharges the purified air from the air outlet volute assembly through the purified air outlet 32 of the casing 10, thereby achieving the effect of indoor air circulation purification.

[0071] When fresh air needs to be introduced, the outdoor fresh air enters the air inlet volute assembly through the fresh air inlet, completes three - stage filtering in sequence through the air inlet filter, the filter, and the air outlet filter, and then discharges the purified air from the air outlet volute assembly through the purified air outlet 32 of the casing 10, achieving a large fresh air volume and a large purification volume, thereby achieving the purpose of introducing purified fresh air.
