[0025] Before the technical solutions of the present application are explained, the background art of the present application is described.

[0026] As the most expandable home appliance product, the air conditioner indoor unit has integrated more and more functions in recent years, such as humidification function, etc.

[0027] When the air conditioner indoor unit is integrated with the humidification function, since the user needs to replace the water tank in the water tank module and clean the evaporation cavity of the steam generator, and the steam generator is covered in the air conditioner housing of the air conditioner indoor unit, there is a need to open the water tank module to take out the water tank and open the air conditioner housing to take out the steam generator.

[0028] However, when the water tank module is opened or the air conditioner housing is opened, accidents such as electric shock or scalding may occur, so a power-off function needs to be designed. However, since the power needs to be turned off whether the water tank module is opened or the air conditioner housing is opened, the function is relatively complex, resulting in a relatively complex structure and control logic for implementing the power-off function and a relatively high cost. Based on this, the present application provides a new air conditioner indoor unit to solve the above problems.

[0029] The technical solutions of the present application will be described below in conjunction with specific embodiments and drawings.

[0030] 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 a structural schematic diagram of the air conditioner indoor unit 100 in another view.

[0031] Referring to Figure 1 and Figure 2 , the air conditioner indoor unit 100 includes an air conditioner housing 1, and the air conditioner housing 1 is provided with an air conditioner air inlet 11 and an air conditioner air outlet 12.

[0032] The material of the air conditioner housing 1 can be plastic or metal, etc., which is not limited in the present embodiment. The air conditioner air inlet 11 can be provided on the back of the air conditioner housing 1, and the air conditioner air outlet 12 can be provided on the front of the air conditioner housing 1. Of course, the air conditioner air inlet 11 and the air conditioner air outlet 12 can also be provided on other faces of the air conditioner housing 1, such as the side of the air conditioner housing 1, which is not limited in the present embodiment.

[0033] In addition, the shape of the air conditioner housing 1 can be a cylinder or a cuboid, etc., which is not limited in the present embodiment. The air conditioner indoor unit 100 can be a floor-standing air conditioner indoor unit or a wall-mounted air conditioner indoor unit, etc., which is not limited in the present embodiment.

[0034] It should be noted that the front of the air conditioner housing 1 can be understood as the front of the entire air conditioner indoor unit 100, and the side and back of the air conditioner housing 1 can also be understood as the side and back of the entire air conditioner indoor unit 100.

[0035] In some embodiments, referring to Figure 3 , Figure 3 is Figure 1FIG. 6 is a structural schematic diagram of the air conditioner indoor unit 100 in FIG. 1 after omitting part of the structure, and the air conditioner indoor unit 100 further comprises a heat exchanger 2, which is arranged in the air conditioner casing 1 and is used for heat exchanging air entering the air conditioner casing 1 through the air conditioner air inlet 11, and the heat-exchanged air is blown out of the air conditioner casing 1 through the air conditioner air outlet 12.

[0036] In this embodiment, since the heat exchanger 2 is arranged in the air conditioner casing 1 and can heat exchange air entering the air conditioner casing 1 through the air conditioner air inlet 11, and the heat-exchanged air can be blown out of the air conditioner casing 1 through the air conditioner air outlet 12, when the air conditioner indoor unit 100 comprises the heat exchanger 2, the air can be heated or cooled under the action of the heat exchanger 2, and thus the purpose of heating or cooling the indoor can be achieved.

[0037] Figure 4 is Figure 1 FIG. 7 is a structural schematic diagram of the detachable casing 34 in FIG. 1 after being opened, Figure 5 is Figure 4 FIG. 8 is an exploded view of the humidification module 3 in FIG. 1. Referring to Figure 1 , Figure 4 and Figure 5 , the air conditioner indoor unit 100 further comprises the humidification module 3, and the humidification module 3 comprises a mounting bracket 31, which is arranged in the air conditioner casing 1.

[0038] In this embodiment, the material of the mounting bracket 31 can be plastic or metal, and the embodiment is not limited in this regard. The mounting bracket 31 can be a plate structure or a fence structure, and the embodiment is not limited in this regard.

[0039] When the humidification module 3 comprises the mounting bracket 31, the mounting bracket 31 can be used as a base for mounting other components of the humidification module 3, so that the other components of the humidification module 3 can be stably and reliably mounted.

[0040] In some embodiments, referring to Figure 5 and Figure 6 , Figure 6 is Figure 5 FIG. 8 is an exploded view of the humidification module 3 in FIG. 1, and the humidification module 3 further comprises a steam generator 32, which is detachably mounted on the mounting bracket 31.

[0041] By detachably mounting the steam generator 32 to the mounting bracket 31, on the one hand, the mounting bracket 31 can play a role in fixing the steam generator 32, so that the steam generator 32 can be more stably mounted to the mounting bracket 31. On the other hand, the steam generator 32 can be very flexible to be detached from the mounting bracket 31, in this way, when the evaporation cavity of the steam generator 32 is dirty after long time use, the steam generator 32 can be detached from the mounting bracket 31 for cleaning, and thus the work of cleaning the evaporation cavity of the steam generator 32 can be made more convenient.

[0042] In some embodiments, referring to Figure 5 , Figure 6 and Figure 7 , Figure 7 is Figure 6 an exploded view of the water tank module 33, the humidifying module 3 further comprises a water tank module 33, the water tank module 33 is detachably mounted in the air conditioner shell 1 and the water tank 331 of the water tank module 33 is in communication with the steam generator 32.

[0043] Since the water tank 331 of the water tank module 33 is in communication with the steam generator 32, the water in the water tank 331 can enter the inner cavity in the steam generator 32, so that the steam generator 32 can make steam by evaporation.

[0044] In particular, referring to Figure 6 and Figure 7 , the water tank module 33 can further comprise a water tank cover 333, the water tank cover 333 is detachably mounted in the air conditioner shell 1, and the water tank 331 is detachably mounted in the water tank cover 333, in this way, the water tank cover 333 can form protection for the water tank 331, so as to improve the durability of the water tank 331.

[0045] It should be noted that the above-mentioned water tank cover 333 is detachably mounted in the air conditioner shell 1, which can be understood in a broad sense, in one understanding, the water tank cover 333 can be directly detached from the air conditioner shell 1. In another possible understanding, the bottom end of the water tank cover 333 is rotatably mounted in the air conditioner shell 1 and the top end of the water tank cover 333 can be turned out of the air conditioner shell 1.

[0046] In some embodiments, referring to Figure 5 and Figure 6 , the humidifying module 3 further comprises a detachable shell 34, the detachable shell 34 is detachably mounted to the mounting bracket 31, and the steam generator 32 is located between the detachable shell 34 and the mounting bracket 31.

[0047] Since the steam generator 32 is located between the detachable shell 34 and the mounting support 31, when the detachable shell 34 is mounted on the mounting support 31, on the one hand, the detachable shell 34 can play a role in protecting the steam generator 32, so as to improve the service life of the steam generator 32. On the other hand, the detachable shell 34 can play a role in covering the steam generator 32, so as to avoid the situation that the user is scalded by the steam generator 32.

[0048] Among them, the implementation manner that the detachable shell 34 is detachably mounted on the mounting support 31 has various kinds, for example, the detachable mounting on the mounting support 31 can be realized by the buckle fastening manner, of course, the detachable mounting on the mounting support 31 can also be realized by other manners, for example, the screw manner, and the embodiment does not limit this.

[0049] In some embodiments, referring to Figure 5 、 Figure 8 and Figure 9 , Figure 8 is Figure 5 a partial enlarged view at the A position in FIG. 8, Figure 9 is Figure 5 an exploded view of the humidification module 3 in FIG. 8 from another perspective, and the air conditioner indoor unit 100 further comprises a multi-control switch module 4.

[0050] Among them, the multi-control switch module 4 can be located in the air conditioner shell 1, when the multi-control switch module 4 is located in the air conditioner shell 1, the air conditioner shell 1 can form protection for the multi-control switch module 4 in the periphery of the multi-control switch module 4, so that the environment in which the multi-control switch module 4 is located is more independent, thereby the running stability of the multi-control switch module 4 can be improved to a certain extent.

[0051] Figure 10 is Figure 9 a partial enlarged view at the B position in FIG. 8, Figure 11 is Figure 9 a structural schematic view of the multi-control switch module 4 in FIG. 8, referring to Figure 9 、 Figure 10 and Figure 11 In some embodiments, the multi-control switch module 4 comprises a mounting seat 41, and the mounting seat 41 is arranged in the air conditioner shell 1.

[0052] Among them, the implementation manner that the mounting seat 41 is arranged in the air conditioner shell 1 has various kinds, in one of the possible implementation manners, the mounting seat 41 can be mounted on the air conditioner shell 1 or the mounting support 31, etc., as long as the mounting seat 41 is located in the air conditioner shell 1, and the embodiment does not limit this.

[0053] In some embodiments, the multi-control switch module 4 further comprises a sliding piece 42, and the sliding piece 42 slides along a first direction (X) Figure 9The sliding member 42 is slidably arranged in the first direction (i.e. the Y-axis direction) in the mounting base 41.

[0054] The sliding member 42 can be in a shaft structure or a plate structure, and the present embodiment does not limit the structure of the sliding member 42.

[0055] In addition, the sliding member 42 is slidably arranged in the first direction (i.e. the Y-axis direction) in the mounting base 41. Figure 9 In one possible implementation, the sliding member 42 can be slidably arranged in the first direction (i.e. the Y-axis direction) in the mounting base 41 by using a linear bearing. Figure 9 Of course, the sliding member 42 can be slidably arranged in the first direction (i.e. the Y-axis direction) in the mounting base 41 by using other means, and the present embodiment does not limit the means for slidably arranging the sliding member 42 in the first direction (i.e. the Y-axis direction) in the mounting base 41.

[0056] In some embodiments, referring to Figure 9 and Figure 11 , the multi-control switch module 4 further comprises an elastic member 43. Figure 9 When the elastic member 43 is deformed, the elastic member 43 can provide a spring force for the sliding member 42 to slide in the first direction (i.e. the Y-axis positive direction).

[0057] The elastic member 43 can be a spring. Figure 9 In one possible implementation, when the spring is compressed, the spring can provide a spring force for the sliding member 42 to slide in the first direction (i.e. the Y-axis positive direction). Figure 9 In another possible implementation, when the spring is stretched, the spring can provide a spring force for the sliding member 42 to slide in the first direction (i.e. the Y-axis positive direction). Figure 9 As long as the spring force for the sliding member 42 to slide in the first direction (i.e. the Y-axis positive direction) can be provided, the present embodiment does not limit the implementation of the spring.

[0058] In some embodiments, referring to Figure 11 and Figure 12 , Figure 12 is Figure 11 a disassembled view of the multi-control switch module 4.

[0059] Since the micro switch 44 is electrically connected to the steam generator 32, in one possible implementation, when the micro switch 44 is open, the steam generator 32 can be powered off, so that the steam generator 32 can stop generating steam.

[0060] The aforementioned contact element 441 can be a spring of the micro switch 44. When the spring is subjected to pressure, the spring closes and the micro switch 44 closes. When the pressure on the spring is removed, the spring opens and the micro switch 44 opens.

[0061] In some embodiments, see Figure 13 , Figure 13 yes Figure 5 The humidification module 3 is shown in a structural diagram from another perspective after some of its structure has been omitted (the detachable housing 34 is in a closed state). Figure 14 yes Figure 13 See the enlarged view of the middle C position. Figure 13 and Figure 14 A recess 332 is provided on one of the detachable housing 34 and the water tank module 33. Figure 14 The water tank module 33 has a recess 332, and the other of the detachable housing 34 and the water tank module 33 abuts against the sliding member 42 along the first direction. Figure 14 The detachable housing 34 abuts against the sliding member 42 along the first direction, driving the sliding member 42 along the negative direction of the first direction. Figure 14 The sliding (in the negative direction of the Y-axis) causes the elastic element 43 to deform, wherein one of them ( Figure 14 The water tank module 33 in the middle abuts against the contact element 441 to close the micro switch 44.

[0062] See Figure 15 , Figure 15 yes Figure 13 A schematic diagram of the humidification module 3 when the detachable housing 34 is opened. Figure 16 yes Figure 15 A partial enlarged view of the humidification module 3 at position D, when the other ( Figure 15 When the removable housing 34 is removed, the elastic element 43 drives the sliding element 42 along the positive direction of the first direction ( Figure 16 The contact 441 slides in the positive direction of the Y-axis and moves into the recess 332 to disconnect the micro switch 44.

[0063] Since one of the detachable housing 34 and the water tank module 33 is provided with a recess 332, when both the humidification module 3 and the detachable housing 34 are installed in the air conditioner housing 1, the other of the detachable housing 34 and the water tank module 33 can abut against the sliding member 42 in the first direction. When the other of the detachable housing 34 and the water tank module 33 abuts against the sliding member 42 in the first direction, the sliding member 42 can be pushed in the negative direction of the first direction. Figure 14 Sliding along the negative Y-axis can cause the contact element 441 to slide out of the recess 332 and abut against the one of them. Figure 14When the one of the detachable shell 34 and the water tank module 33 is detached from the air conditioner shell 1, the one and the contact piece 441 will be out of contact. When the one and the contact piece 441 are out of contact, the pressure on the contact piece 441 will disappear, and the micro switch 44 can be turned off. When the micro switch 44 is turned off, the steam generator 32 can be powered off, and the steam generator 32 can stop generating steam, so as to avoid the situation of electric shock or scalding the user.

[0064] When the one of the detachable shell 34 and the water tank module 33 is detached from the air conditioner shell 1, the one and the contact piece 441 will be out of contact. When the one and the contact piece 441 are out of contact, the pressure on the contact piece 441 will disappear, and the micro switch 44 can be turned off. When the micro switch 44 is turned off, the steam generator 32 can be powered off, and the steam generator 32 can stop generating steam, so as to avoid the situation of electric shock or scalding the user.

[0065] When the other of the detachable shell 34 and the water tank module 33 is detached from the air conditioner shell 1, the elastic piece 43 can drive the sliding piece 42 to slide along the positive direction of the first direction (the positive direction of the Y-axis in the figure) Figure 16 When the other of the detachable shell 34 and the water tank module 33 is detached from the air conditioner shell 1, the elastic piece 43 can drive the sliding piece 42 to slide along the positive direction of the first direction (the positive direction of the Y-axis in the figure)

[0066] It can be seen that only when the detachable shell 34 and the water tank module 33 are both installed on the air conditioner shell 1, the contact piece 441 can be pressed, the micro switch 44 can be closed, and the steam generator 32 can start to generate steam. When any one of the detachable shell 34 and the water tank module 33 is detached, the pressure on the contact piece 441 will disappear, the micro switch 44 will be turned off, and the steam generator 32 will stop generating steam. In this way, the situation of electric shock or scalding the user can be avoided when any one of the detachable shell 34 and the water tank module 33 is detached.

[0067] In addition, under the cooperation of the sliding piece 42, the elastic piece 43, the micro switch 44 and the recessed part 332, the detachable shell 34, the water tank module 33 and the micro switch 44 can be linked, that is, through the same micro switch 44, the steam generator 32 can be powered off when any one of the detachable shell 34 and the water tank module 33 is detached. On the one hand, the control logic for powering off the steam generator 32 can be simplified, and on the other hand, the cost of the multi-control switch module 4 can be reduced, and the cost of the entire air conditioner indoor unit 100 can be reduced.

[0068] It should be noted that the recess 332 can be a groove or a counterbore, and the present embodiment does not limit the same.

[0069] Referring to Figure 1 , Figure 2 and Figure 3 , the air conditioner indoor unit 100 comprises an air conditioner shell 1 and a heat exchanger 2, wherein the air conditioner shell 1 is provided with an air conditioner air inlet 11 and an air conditioner air outlet 12.

[0070] Referring to Figure 4 , the air conditioner indoor unit 100 further comprises a humidification module 3 and a multi-control switch module 4, and the heat exchanger 2 is arranged in the air conditioner shell 1 and used for heat exchange of air entering the air conditioner shell 1 through the air conditioner air inlet 11, and the heat-exchanged air is blown out of the air conditioner shell 1 through the air conditioner air outlet 12.

[0071] Referring to Figure 6 , the humidification module 3 comprises a mounting bracket 31, a steam generator 32, a water tank module 33 and a detachable shell 34, wherein the mounting bracket 31 is arranged in the air conditioner shell 1, the steam generator 32 is detachably mounted on the mounting bracket 31, the water tank module 33 is detachably mounted in the air conditioner shell 1 and a water tank 331 of the water tank module 33 is in communication with the steam generator 32, and the detachable shell 34 is detachably mounted on the mounting bracket 31, and the steam generator 32 is located between the detachable shell 34 and the mounting bracket 31.

[0072] Referring to Figure 9 , Figure 14 and Figure 16 , the multi-control switch module 4 comprises a mounting seat 41, a sliding piece 42, an elastic piece 43 and a micro switch 44, wherein the mounting seat 41 is arranged in the air conditioner shell 1, the sliding piece 42 is slidably arranged in the mounting seat 41 along a first direction, the elastic piece 43 can provide a positive sliding force of the sliding piece 42 along the first direction when deformed, and the micro switch 44 is arranged on the sliding piece 42 and electrically connected to the steam generator 32, and the micro switch 44 has a contact piece 441.

[0073] One of the detachable shell 34 and the water tank module 33 is provided with a recess 332, and the other of the detachable shell 34 and the water tank module 33 abuts against the sliding piece 42 along the first direction, drives the sliding piece 42 to slide in the negative direction of the first direction to deform the elastic piece 43, and the one abuts against the contact piece 441 to make the micro switch 44 closed. When the other is detached, the elastic piece 43 drives the sliding piece 42 to slide in the positive direction of the first direction, drives the contact piece 441 to slide into the recess 332 to make the micro switch 44 open.

[0074] In this embodiment, only when the detachable shell 34 and the water tank module 33 are both installed on the air conditioner shell 1, the contact piece 441 is pressed, the micro switch 44 is closed, and the steam generator 32 starts to generate steam. When any one of the detachable shell 34 and the water tank module 33 is removed, the pressure on the contact piece 441 disappears, the micro switch 44 is opened, and the steam generator 32 stops generating steam. In this way, it can be well avoided that the user is scalded or the electric leakage occurs when any one of the detachable shell 34 and the water tank module 33 is removed.

[0075] In addition, under the cooperation of the sliding piece 42, the elastic piece 43, the micro switch 44, and the recess 332, the detachable shell 34, the water tank module 33, and the micro switch 44 can be linked, that is, through the same micro switch 44, the purpose of powering off the steam generator 32 can be achieved when any one of the detachable shell 34 and the water tank module 33 is removed. On the one hand, the control logic for powering off the steam generator 32 can be simple, and on the other hand, the cost of the multi-control switch module 4 can be reduced, and thus the cost of the entire air conditioner indoor unit 100 can be reduced.

[0076] In some embodiments, referring to Figure 13 and Figure 14 , the recess 332 is arranged on the water tank module 33, and the detachable shell 34 abuts against the sliding piece 42 along the first direction (Y-axis direction in Figure 14 ).

[0077] Since the thickness of the water tank module 33 is usually thick, there is a large thickness allowance for processing the recess 332, and thus by arranging the recess 332 on the water tank module 33, the processing difficulty of the recess 332 can be reduced.

[0078] When the water tank module 33 includes the water tank 331 and the water tank cover 333, specifically, the recess 332 can be arranged on the water tank cover 333. By arranging the recess 332 on the water tank cover 333, the recess 332 arranged on the water tank 331 can be avoided, and thus the mechanical strength of the water tank 331 can be avoided to be reduced, so that the durability of the water tank 331 can be improved.

[0079] Of course, in other embodiments, referring to Figure 18 and Figure 19 , Figure 18 is another exploded view of a humidifying module provided in an embodiment of the present application, Figure 19 is Figure 18 a local enlarged view at the E position in FIG. 8, the recess 332 can be arranged on the detachable shell 34, and the water tank module 33 abuts against the sliding piece 42 along the first direction (X-axis direction in Figure 18 ).

[0080] When the recess 332 is provided on the detachable housing 34, the water tank module 33 moves along the first direction ( Figure 18 When the slider 42 (in the X-axis direction) abuts against the slider 42, it can drive the slider 42 along the negative direction of the first direction ( Figure 18 The elastic element 43 slides along the positive X-axis direction to deform the removable housing 34, which then abuts against the contact element 441 to close the micro switch 44. When the water tank module 33 is removed, the elastic element 43 drives the sliding element 42 along the positive X-axis direction to deform the elastic element 43. Figure 18 The contact 441 slides into the recess 332 (in the negative X-axis direction) to disengage the micro switch 44.

[0081] In some embodiments, see Figure 11 The elastic element 43 is sleeved on the sliding element 42.

[0082] By fitting the elastic element 43 onto the sliding element 42, the sliding element 42 can support and guide the elastic element 43, thereby preventing or reducing the occurrence of the elastic element 43 tilting or leaning during deformation.

[0083] Among them, the elastic element 43 can be a spring. When the elastic element 43 is a spring, the elastic element 43 is sleeved on the outer peripheral wall of the sliding element 42.

[0084] In some embodiments, see Figure 14 The elastic element 43 abuts against the mounting base 41 and the micro switch 44 at both ends along the first direction, and the micro switch 44 is located along the first direction near the other of the mounting base 41. Figure 14 One side of the detachable housing 34 in the middle.

[0085] Since the two ends of the elastic element 43 abut against the mounting base 41 and the micro switch 44 respectively along the first direction, the micro switch 44 is located along the first direction near the other of the aforementioned components on the mounting base 41. Figure 14 The removable housing 34 is located on one side of the air conditioner housing 1. Therefore, when the other (removable housing 34) is installed on the air conditioner housing 1, it will push the micro switch 44 in the negative direction of the first direction. Figure 14 The elastic element 43 is compressed as it moves closer to the mounting base 41 in the negative direction of the Y-axis.

[0086] When the other of the above (removable housing 34) is removed from the air conditioner housing 1, the elastic element 43 will push the micro switch 44 in the positive direction of the first direction ( Figure 14 The movement is away from the mounting base 41 in the positive direction of the Y-axis. It can be seen that the elastic force that provides positive sliding force along the first direction to the sliding member 42 can be achieved by utilizing the compressed feature of the elastic member 43. The principle is very simple and can reduce the cost of the multi-control switch module 4 to a certain extent.

[0087] In some embodiments, see Figure 11 and Figure 12 The multi-control switch module 4 also includes a base 45, which is disposed on the sliding member 42. A micro switch 44 is disposed on the base 45, and an elastic member 43 is disposed at both ends along the first direction. Figure 11 (In the Y-axis direction) respectively abuts against the mounting base 41 and the base body 45.

[0088] Since the micro switch 44 is located on the base 45, the base 45 can serve to install the micro switch 44, so that the micro switch 44 can be more stably fixed to the slider 42.

[0089] In addition, since the two ends of the elastic element 43 abut against the mounting base 41 and the base 45 respectively along the first direction, the base 45 can protect the micro switch 44 and prevent the elastic element 43 from directly abutting against the micro switch 44 and causing damage to the micro switch 44.

[0090] Among them, see Figure 12 The aforementioned base 45 can be a U-shaped structure or any other arbitrary shape; this embodiment does not limit this.

[0091] See Figure 11 and Figure 12 The aforementioned sliding member 42 is along the first direction ( Figure 11 There are multiple ways to implement the sliding arrangement of the mounting base 41 in the Y-axis direction. In one possible implementation, the mounting base 41 is provided with a through hole 411 that extends through the mounting base 41 in the first direction, and the sliding member 42 is slidably disposed in the through hole 411 in the first direction.

[0092] Since the slider 42 is slidably disposed in the through hole 411 along the first direction, the through hole 411 can guide the slider 42 to slide along the first direction, making the slider 42 slide more smoothly and with higher sliding accuracy.

[0093] To prevent the slider 42 from rotating circumferentially along the through hole 411 when sliding in the first direction within the through hole 411, in some embodiments, see... Figure 11 and Figure 12 The sliding member 42 is configured to prevent rotation relative to the mounting base 41 along the circumference of the through hole 411.

[0094] By setting the slider 42 to prevent rotation relative to the mounting base 41 along the circumference of the through hole 411, the circumference rotation of the slider 42 along the through hole 411 can be prevented, thereby preventing the micro switch 44 from deviating from the preset trajectory, thus ensuring the reliability of the operation of the multi-control switch module 4.

[0095] It should be noted that the above-mentioned sliding member 42 is rotationally fixed relative to the mounting base 41 along the circumference of the through hole 411 in multiple ways. In one possible implementation, one of the outer circumferential wall of the sliding member 42 and the inner circumferential wall of the through hole 411 is provided with a protrusion 421 extending in the first direction, and the other is provided with a groove 4111 extending in the first direction. The protrusion 421 is slidably arranged in the groove 4111 in the first direction.

[0096] Since the protrusion 421 is slidably arranged in the groove 4111 in the first direction, the cooperation of the protrusion 421 and the groove 4111 can play a role in rotationally fixing, thereby avoiding the rotation of the sliding member 42 along the circumference of the through hole 411.

[0097] Of course, the rotationally fixed purpose of the sliding member 42 relative to the mounting base 41 along the circumference of the through hole 411 can also be achieved in another possible way. For example, the sliding member 42 can be a quadrangular prism, and the through hole 411 can be a rectangular hole. In this way, the cooperation of the rectangular hole and the quadrangular prism can also achieve the rotationally fixed purpose of the sliding member 42 relative to the mounting base 41 along the circumference of the through hole 411.

[0098] In some embodiments, referring to Figure 1 , Figure 4 and Figure 6 , the air conditioner indoor unit 100 includes a front surface 13 and a side surface 14. The detachable shell 34 forms at least part of the front surface 13, and the water tank module 33 is detachably mounted in the air conditioner housing 1 through the side surface 14.

[0099] That is, the detachable shell 34 and the water tank module 33 are located at different two surfaces of the air conditioner indoor unit 100. In this way, on the one hand, the mutual interference between the detachable shell 34 and the water tank module 33 can be avoided, and on the other hand, the detachable shell 34 and the water tank module 33 are located in different two directions of the multi-control switch module 4. In this way, the sliding direction of the sliding member 42 and the force direction of the contact member 441 are different directions, which is beneficial to the structural layout of the sliding member 42 and the contact member 441 of the micro switch 44, and can avoid the mutual interference between the sliding member 42 and the contact member 441 of the micro switch 44.

[0100] When the air conditioner housing 1 is a rectangular parallelepiped, the above-mentioned front surface 13 refers to the surface of the air conditioner indoor unit 100 facing the user, and the above-mentioned side surface 14 refers to the left and right two surfaces of the air conditioner indoor unit 100.

[0101] In some embodiments, referring to Figure 17 , Figure 17 is Figure 3A kind of exploded view of air conditioner indoor unit 100 in it, air conditioner indoor unit 100 further include fresh air module 5, fresh air module 5 is set in air conditioner shell 1.

[0102] When air conditioner indoor unit 100 further include fresh air module 5, can make this air conditioner indoor unit 100 also integrated with fresh air function, function is more plural, use experience is better.

[0103] In some embodiments, referring to Figure 2 、 Figure 5 And Figure 17 , fresh air module 5 includes fresh air volute 51 and fresh air fan 52, air conditioner shell 1 is provided with fresh air inlet 15 and fresh air outlet 16, fresh air volute 51 is communicated with fresh air inlet 15 and fresh air outlet 16 respectively, fresh air fan 52 is set in fresh air volute 51. Steam generator 32 has steam outlet 321, and steam outlet 321 is communicated with fresh air outlet 16.

[0104] Since fresh air volute 51 is communicated with fresh air inlet 15 and fresh air outlet 16 respectively, and fresh air fan 52 is set in fresh air volute 51, when fresh air fan 52 starts to act, the fresh air outside can be sucked into fresh air volute 51 for filtering through fresh air inlet 15, and the filtered fresh air can be blown to the room through fresh air outlet 16, so that the purpose of improving indoor air quality can be achieved.

[0105] Since steam generator 32 has steam outlet 321, and steam outlet 321 is communicated with fresh air outlet 16, the steam generated by steam generator 32 can reach fresh air outlet 16 through steam outlet 321 and mix with the fresh air at fresh air outlet 16. In this way, on the one hand, the fresh air can be more humid, and on the other hand, when the fresh air blows out of fresh air outlet 16, it can drive the steam to move further into the room, thereby enabling the humidification of the farthest place in the room, so as to further improve the use experience of air conditioner indoor unit 100.

[0106] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
