Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to an indoor unit of an air conditioner. Background Technology

[0002] As the most expandable home appliance, air conditioner indoor units have integrated more and more functions in recent years, such as humidification.

[0003] When the indoor unit of an air conditioner integrates a humidification function, since the user needs to replace the water tank in the water tank module and clean the evaporation chamber of the steam generator, and the steam generator is covered inside the air conditioner casing of the indoor unit, there is a need to open the water tank module to remove the water tank and open the air conditioner casing to remove the steam generator.

[0004] However, opening the water tank module or the air conditioner casing may cause accidents (such as electric leakage or burns), therefore a power-off function needs to be designed. However, since power must be cut off regardless of whether the water tank module or the air conditioner casing is opened, and the function is relatively complex, the control logic for implementing the power-off function is complex and the cost is high. Summary of the Invention

[0005] This application discloses an indoor air conditioner unit, whose control logic for achieving power-off function is relatively simple and has a low cost.

[0006] To achieve the above objectives, this application discloses an indoor air conditioning unit, comprising:

[0007] An air conditioner housing, wherein an air conditioner inlet and an air conditioner outlet are provided on the air conditioner housing;

[0008] A heat exchanger, wherein the heat exchanger is disposed within the air conditioner housing;

[0009] Humidification module, the humidification module includes:

[0010] Mounting bracket, which is disposed inside the air conditioner housing;

[0011] A steam generator, wherein the steam generator is detachably mounted on the mounting bracket;

[0012] A water tank module, wherein the water tank module is detachably installed inside the air conditioner housing and the water tank of the water tank module is connected to the steam generator;

[0013] A detachable housing is detachably mounted to the mounting bracket, and the steam generator is located between the detachable housing and the mounting bracket;

[0014] The indoor unit of the air conditioner also includes: a multi-control switch module, the multi-control switch module comprising:

[0015] Mounting bracket, wherein the mounting bracket is disposed inside the air conditioner housing;

[0016] A sliding member, which is slidably disposed on the mounting base along a first direction;

[0017] An elastic element that, when deformed, provides a spring force for the slider to slide in the positive direction along the first direction;

[0018] A micro switch, wherein the micro switch is disposed on the sliding member and electrically connected to the steam generator, the micro switch having a contact element;

[0019] Optionally, the recess is provided on the water tank module, and the detachable housing abuts against the sliding member along the first direction.

[0020] Optionally, the elastic element is sleeved on the sliding element.

[0021] Optionally, the two ends of the elastic element along the first direction abut against the mounting base and the micro switch, respectively, and the micro switch is located on the side of the mounting base closer to the other along the first direction.

[0022] Optionally, the multi-control switch module further includes:

[0023] The base is disposed on the sliding member, the micro switch is disposed on the base, and the two ends of the elastic member along the first direction respectively abut against the mounting base and the base.

[0024] Optionally, the mounting base is provided with a through hole extending through the mounting base along the first direction, and the sliding member is slidably disposed in the through hole along the first direction.

[0025] Optionally, the slider is anti-rotational relative to the mounting base along the circumferential direction of the through hole.

[0026] Optionally, one of the outer peripheral wall of the slider and the inner peripheral wall of the through hole is provided with a protrusion extending along the first direction, and the other is provided with a groove extending along the first direction, wherein the protrusion is slidably disposed in the groove along the first direction.

[0027] Optionally, the indoor unit of the air conditioner further includes:

[0028] The front side, wherein the removable housing forms at least a portion of the front side; and,

[0029] On the side, the water tank module is detachably installed inside the air conditioner housing via the side.

[0030] Optionally, the indoor unit of the air conditioner further includes:

[0031] A fresh air module, wherein the fresh air module is disposed within the air conditioner housing, the fresh air module comprising:

[0032] The air conditioner housing has a fresh air inlet and a fresh air outlet, and the fresh air volute is connected to the fresh air inlet and the fresh air outlet respectively.

[0033] Fresh air fan, wherein the fresh air fan is disposed inside the fresh air volute;

[0034] The steam generator has a steam outlet, which is connected to the fresh air outlet.

[0035] Compared with the prior art, the beneficial effects of this application are as follows:

[0036] In this application, the contact elements are only pressurized and the microswitch closes, allowing the steam generator to begin producing steam, when both the removable housing and the water tank module are installed within the air conditioner casing. When either the removable housing or the water tank module is removed, the pressure on the contact elements disappears, the microswitch opens, and the steam generator ceases to produce steam. This effectively prevents burns to users or electrical leaks that could occur when either the removable housing or the water tank module is removed.

[0037] Furthermore, with the aforementioned cooperation of the sliding component, elastic component, micro switch, and recessed portion, the detachable housing, water tank module, and micro switch can be linked together. That is, regardless of whether either the detachable housing or the water tank module is removed, the steam generator can be powered off using the same micro switch. On the one hand, this simplifies the control logic for powering off the steam generator, and on the other hand, it reduces the cost of the multi-control switch module, thereby reducing the overall cost of the indoor air conditioning unit.

[0070] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0071] As the most expandable home appliance, air conditioner indoor units have integrated more and more functions in recent years, such as humidification.

[0072] When the indoor unit of an air conditioner integrates a humidification function, since the user needs to replace the water tank in the water tank module and clean the evaporation chamber of the steam generator, and the steam generator is covered inside the air conditioner casing of the indoor unit, there is a need to open the water tank module to remove the water tank and open the air conditioner casing to remove the steam generator.

[0073] However, opening the water tank module or the air conditioner casing may cause accidents (such as electric leakage or burns), therefore a power-off function is required. However, since opening either the water tank module or the air conditioner casing requires a power-off function, and the function is complex, the structure and control logic for implementing the power-off function are also complex and costly. Therefore, this application provides a new air conditioner indoor unit to solve the above problems.

[0074] The technical solution of this application will be described below with reference to specific embodiments and accompanying drawings.

[0075] Figure 1 This is a structural schematic diagram of an air conditioner indoor unit 100 provided in one embodiment of this application. Figure 2 yes Figure 1A schematic diagram of the structure of the indoor air conditioner unit 100 from another perspective.

[0076] See Figure 1 and Figure 2 The indoor unit of the air conditioner 100 includes an air conditioner housing 1, on which an air conditioner air inlet 11 and an air conditioner air outlet 12 are provided.

[0077] The air conditioner housing 1 can be made of plastic or metal, etc., and this embodiment does not limit the material. The air inlet 11 can be located on the rear of the air conditioner housing 1, and the air outlet 12 can be located on the front of the air conditioner housing 1. Of course, the air inlet 11 and the air outlet 12 can also be located on other surfaces of the air conditioner housing 1, such as the side of the air conditioner housing 1. This embodiment does not limit the material.

[0078] Furthermore, the shape of the air conditioner casing 1 can be cylindrical, cuboid, etc., and this embodiment does not limit this. The air conditioner indoor unit 100 can be a floor-standing air conditioner indoor unit or a wall-mounted air conditioner indoor unit, etc., and this embodiment does not limit this either.

[0079] It should be noted that the front of the air conditioner housing 1 mentioned above can be understood as the front of the entire indoor air conditioner unit 100, and the sides and rear of the air conditioner housing 1 mentioned above can also be understood as the sides and rear of the entire indoor air conditioner unit 100.

[0080] In some embodiments, see Figure 3 , Figure 3 yes Figure 1 The diagram shows the structure of the indoor unit 100 of the air conditioner, with some parts omitted. The indoor unit 100 of the air conditioner also includes a heat exchanger 2, which is installed inside the air conditioner casing 1 and is used to exchange heat with the air entering the air conditioner casing 1 through the air inlet 11. The air after heat exchange is blown out of the air conditioner casing 1 through the air outlet 12.

[0081] Since the heat exchanger 2 is installed inside the air conditioner casing 1, and the heat exchanger 2 can exchange heat with the air entering the air conditioner casing 1 through the air inlet 11, and the air after heat exchange can be blown out of the air conditioner casing 1 through the air outlet 12, when the air conditioner indoor unit 100 includes the heat exchanger 2, the air can be heated or cooled under the action of the heat exchanger 2, thereby achieving the purpose of heating or cooling the room.

[0082] Figure 4 yes Figure 1 A schematic diagram of the structure after the detachable housing 34 is opened. Figure 5 yes Figure 4 An exploded view of the humidification module 3. See also... Figure 1 , Figure 4 and Figure 5 The indoor unit 100 of the air conditioner also includes a humidification module 3, which includes a mounting bracket 31 and is disposed inside the air conditioner housing 1.

[0083] The mounting bracket 31 can be made of plastic or metal, etc., and this embodiment does not limit the material. The mounting bracket 31 can be a plate-like structure or a fence-like structure, and this embodiment does not limit the material either.

[0084] When the humidification module 3 includes 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 installed stably and reliably.

[0085] In some embodiments, see Figure 5 and Figure 6 , Figure 6 yes Figure 5 An exploded view of the humidification module 3, which also includes a steam generator 32, which is detachably mounted on the mounting bracket 31.

[0086] By detachably mounting the steam generator 32 to the mounting bracket 31, the mounting bracket 31 serves two purposes: firstly, it secures the steam generator 32, allowing for a more stable installation; secondly, it allows for easy removal of the steam generator 32 from the mounting bracket 31. This makes it convenient to clean the steam generator 32's evaporation chamber after prolonged use when it becomes dirty.

[0087] In some embodiments, see Figure 5 , Figure 6 and Figure 7 , Figure 7 yes Figure 6 An exploded view of the water tank module 33 shows that the humidification module 3 also includes a water tank module 33, which is detachably installed inside the air conditioner housing 1 and the water tank 331 of the water tank module 33 is connected to the steam generator 32.

[0088] Since the water tank 331 of the water tank module 33 is connected to the steam generator 32, the water in the water tank 331 can enter the inner cavity of the steam generator 32 so that the steam generator 32 can generate steam by evaporation.

[0089] Specifically, see Figure 6 and Figure 7The water tank module 33 may also include a water tank cover 333, which is detachably installed inside the air conditioner housing 1. The water tank 331 is detachably installed inside the water tank cover 333. In this way, the water tank cover 333 can protect the water tank 331, thereby improving the durability of the water tank 331.

[0090] It should be noted that the above-mentioned water tank cover 333 being detachably installed inside the air conditioner housing 1 can be interpreted in a broad sense. In one interpretation, the water tank cover 333 can be directly removed from the air conditioner housing 1. In another possible interpretation, the bottom end of the water tank cover 333 is rotatably installed inside the air conditioner housing 1, and the top end of the water tank cover 333 can be rotated out from the air conditioner housing 1.

[0091] In some embodiments, see Figure 5 and Figure 6 The humidification module 3 also includes a detachable housing 34, which is detachably mounted on the mounting bracket 31, and the steam generator 32 is located between the detachable housing 34 and the mounting bracket 31.

[0092] Since the steam generator 32 is located between the removable housing 34 and the mounting bracket 31, when the removable housing 34 is installed on the mounting bracket 31, on the one hand, the removable housing 34 can protect the steam generator 32, thereby extending its service life. On the other hand, the removable housing 34 can cover the steam generator 32, thereby preventing the steam generator 32 from scalding the user.

[0093] There are various ways to achieve the detachable housing 34 being detachably installed on the mounting bracket 31. For example, it can be detachably installed on the mounting bracket 31 by means of a snap-fit. Of course, it can also be detachably installed on the mounting bracket 31 by other means, such as by screws. This embodiment does not limit this.

[0094] In some embodiments, see Figure 5 , Figure 8 and Figure 9 , Figure 8 yes Figure 5 A magnified view of a portion of location A in the middle. Figure 9 yes Figure 5 The humidification module 3 is shown in an exploded view from another perspective. The air conditioner indoor unit 100 also includes a multi-control switch module 4.

[0095] Among them, the multi-control switch module 4 can be located inside the air conditioner housing 1. When the multi-control switch module 4 is located inside the air conditioner housing 1, the air conditioner housing 1 can protect the multi-control switch module 4 from the outside, making the environment in which the multi-control switch module 4 is located more independent, thereby improving the operational stability of the multi-control switch module 4 to a certain extent.

[0096] Figure 10 yes Figure 9 A magnified view of a portion of the area at position B. Figure 11 yes Figure 9 See the structural diagram of the multi-control switch module 4. Figure 9 , Figure 10 and Figure 11 In some embodiments, the multi-control switch module 4 includes a mounting base 41, which is disposed inside the air conditioner housing 1.

[0097] There are multiple ways to implement the mounting base 41 being located inside the air conditioner housing 1. In one possible implementation, the mounting base 41 can be installed on the air conditioner housing 1 or the mounting bracket 31, etc., as long as the mounting base 41 is located inside the air conditioner housing 1. This embodiment does not limit this.

[0098] In some embodiments, the multi-control switch module 4 further includes a slider 42, the slider 42 being along a first direction ( Figure 9 The Y-axis direction is slidably mounted on the mounting base 41.

[0099] The aforementioned sliding member 42 can be a shaft-like structure or a plate-like structure, etc., and this embodiment limits it accordingly.

[0100] In addition, the aforementioned slider 42 is along the first direction ( Figure 9 There are several ways to achieve the sliding arrangement of the slider 42 in the mounting base 41 (in the Y-axis direction). In one possible implementation, the slider 42 can be slidably disposed in the first direction (in the Y-axis direction) using a linear bearing. Figure 9 The purpose of the slider 42 being slidably disposed on the mounting base 41 in the Y-axis direction is that, of course, the slider 42 can also be slidably disposed on the mounting base 41 in the first direction in other ways, and this embodiment does not limit this.

[0101] In some embodiments, see Figure 9 and Figure 11 The multi-control switch module 4 also includes an elastic element 43, which, when deformed, provides the sliding element 42 with positive direction along the first direction. Figure 9 The elastic force that causes sliding in the positive Y-axis direction.

[0102] Wherein, the aforementioned elastic element 43 can be a spring. When the elastic element 43 is a spring, in one possible implementation, the spring, when compressed, can provide the sliding element 42 with positive direction along the first direction ( Figure 9 In another possible implementation, the spring provides a sliding force for the slider 42 in the positive direction of the first direction when it is stretched. Figure 9 The elastic force for sliding along the positive Y-axis (in the middle direction). It only needs to provide the sliding member 42 with the elastic force along the positive direction of the first direction (in the middle Y-axis direction). Figure 9 The elastic force that slides in the positive Y-axis direction is sufficient; however, this embodiment does not impose any limitations on this.

[0103] In some embodiments, see Figure 11 and Figure 12 , Figure 12 yes Figure 11 An exploded view of the multi-control switch module 4, which also includes a micro switch 44. The micro switch 44 is disposed on the slider 42 and electrically connected to the steam generator 32. The micro switch 44 has a contact element 441.

[0104] Since the microswitch 44 is electrically connected to the steam generator 32, in one possible implementation, when the microswitch 44 is open, the steam generator 32 can be de-energized, thereby stopping the steam generator 32 from generating steam. When the microswitch 44 is closed, the steam generator 32 can be energized, thereby allowing the steam generator 32 to start generating steam.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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 14 The water tank module 33 and the elastic element 43 deform. When the contact element 441 abuts against one of them, the contact element 441 will be under pressure, which can cause the micro switch 44 to close. When the micro switch 44 is closed, the steam generator 32 can be powered on, thereby realizing the purpose of generating steam through the steam generator 32, so that the indoor unit 100 of the air conditioner can have a humidification function, making its functions more diverse.

[0109] When either the removable housing 34 or the water tank module 33 is removed from the air conditioner housing 1, it will lose contact with the contact element 441. When the removable housing 341 loses contact, the pressure on the contact element 441 will disappear, causing the microswitch 44 to open. When the microswitch 44 opens, the steam generator 32 will be de-energized, thus stopping steam generation and preventing electric shock or burns to the user.

[0110] When the other of the removable housing 34 and water tank module 33 is removed from the air conditioner housing 1, the elastic element 43 can drive the sliding element 42 along the positive direction of the first direction ( Figure 16The contact element 441 slides into the recess 332 along the positive Y-axis. When the contact element 441 slides into the recess 332, the pressure on the contact element 441 disappears, thereby causing the micro switch 44 to open. When the micro switch 44 is open, the steam generator 32 is de-energized, thus stopping the steam generator 32 from producing steam. This prevents electric leakage or burns to the user.

[0111] It is evident that only when both the removable housing 34 and the water tank module 33 are installed on the air conditioner casing 1 can the contact 441 be pressurized, the micro switch 44 close, and the steam generator 32 begin to produce steam. When either the removable housing 34 or the water tank module 33 is removed, the pressure on the contact 441 disappears, the micro switch 44 opens, and the steam generator 32 ceases to produce steam. This effectively prevents burns to the user or electrical leaks when either the removable housing 34 or the water tank module 33 is removed.

[0112] Furthermore, with the aforementioned cooperation of the sliding member 42, the elastic member 43, the micro switch 44, and the recessed portion 332, the detachable housing 34, the water tank module 33, and the micro switch 44 can be linked together. That is, regardless of whether either the detachable housing 34 or the water tank module 33 is removed, the steam generator 32 can be de-energized through the same micro switch 44. On the one hand, this simplifies the control logic for de-energizing the steam generator 32, and on the other hand, it reduces the cost of the multi-control switch module 4, thereby reducing the cost of the entire air conditioning indoor unit 100.

[0113] It should be noted that the recessed portion 332 can be a groove or a countersunk hole, etc., and this embodiment does not limit it.

[0114] See Figure 1 , Figure 2 and Figure 3 The indoor unit 100 of the air conditioner includes an air conditioner housing 1 and a heat exchanger 2. The air conditioner housing 1 is provided with an air conditioner air inlet 11 and an air conditioner air outlet 12.

[0115] See Figure 4 The indoor unit 100 of the air conditioner also includes a humidification module 3 and a multi-control switch module 4. The heat exchanger 2 is installed inside the air conditioner casing 1 and is used to exchange heat with the air entering the air conditioner casing 1 through the air conditioner inlet 11. The air after heat exchange is blown out of the air conditioner casing 1 through the air conditioner outlet 12.

[0116] See Figure 6The humidification module 3 includes a mounting bracket 31, a steam generator 32, a water tank module 33, and a detachable housing 34. The mounting bracket 31 is disposed inside the air conditioner housing 1. The steam generator 32 is detachably mounted on the mounting bracket 31. The water tank module 33 is detachably mounted inside the air conditioner housing 1, and the water tank 331 of the water tank module 33 can communicate with the steam generator 32. The detachable housing 34 is detachably mounted on the mounting bracket 31, and the steam generator 32 is located between the detachable housing 34 and the mounting bracket 31.

[0117] See Figure 9 , Figure 14 and Figure 16 The multi-control switch module 4 includes a mounting base 41, a sliding member 42, an elastic member 43, and a micro switch 44. The mounting base 41 is disposed inside the air conditioner housing 1. The sliding member 42 is slidably disposed on the mounting base 41 along a first direction. The elastic member 43 provides elastic force for the sliding member 42 to slide in the first direction when deformed. The micro switch 44 is disposed on the sliding member 42 and electrically connected to the steam generator 32. The micro switch 44 has a contact member 441.

[0118] One of the detachable housing 34 and the water tank module 33 is provided with a recess 332. The other of the detachable housing 34 and the water tank module 33 abuts against the sliding member 42 along the first direction, causing the sliding member 42 to slide in the negative direction of the first direction, thereby deforming the elastic member 43. The other part abuts against the contact member 441 to close the micro switch 44. When the other part is removed, the elastic member 43 drives the sliding member 42 to slide in the positive direction of the first direction, causing the contact member 441 to slide into the recess 332, thereby opening the micro switch 44.

[0119] In this embodiment, the contact 441 will only be pressurized and the microswitch 44 will only close when both the removable housing 34 and the water tank module 33 are installed on the air conditioner housing 1, allowing the steam generator 32 to start producing steam. When either the removable housing 34 or the water tank module 33 is removed, the pressure on the contact 441 will disappear, the microswitch 44 will open, and the steam generator 32 will no longer produce steam. This effectively prevents burns to the user or electrical leaks when either the removable housing 34 or the water tank module 33 is removed.

[0120] Furthermore, with the aforementioned cooperation of the sliding member 42, the elastic member 43, the micro switch 44, and the recessed portion 332, the detachable housing 34, the water tank module 33, and the micro switch 44 can be linked together. That is, regardless of whether either the detachable housing 34 or the water tank module 33 is removed, the steam generator 32 can be de-energized through the same micro switch 44. On the one hand, this simplifies the control logic for de-energizing the steam generator 32, and on the other hand, it reduces the cost of the multi-control switch module 4, thereby reducing the cost of the entire air conditioning indoor unit 100.

[0121] In some embodiments, see Figure 13 and Figure 14 The recessed portion 332 is provided on the water tank module 33, and the detachable housing 34 is along the first direction ( Figure 14 (In the Y-axis direction) it abuts against the sliding member 42.

[0122] Since the water tank module 33 is usually quite thick, it has a lot of thickness margin for processing the recessed portion 332. Therefore, by setting the recessed portion 332 in the water tank module 33, the processing difficulty of the recessed portion 332 can be reduced.

[0123] Specifically, when the water tank module 33 includes a water tank 331 and a water tank cover 333, the recess 332 can be provided on the water tank cover 333. By providing the recess 332 on the water tank cover 333, the situation where the recess 332 is provided on the water tank 331 can be avoided, thereby preventing a reduction in the mechanical strength of the water tank 331 and improving the durability of the water tank 331.

[0124] Of course, in other embodiments, see Figure 18 and Figure 19 , Figure 18 This is an exploded view of another humidification module provided in one embodiment of this application. Figure 19 yes Figure 18 A partial enlarged view at position E shows that the recessed portion 332 can be disposed on the detachable housing 34, and the water tank module 33 is along the first direction ( Figure 18 (In the X-axis direction) it abuts against the sliding member 42.

[0125] 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 18The contact 441 slides into the recess 332 (in the negative X-axis direction) to disengage the micro switch 44.

[0126] In some embodiments, see Figure 11 The elastic element 43 is sleeved on the sliding element 42.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] It should be noted that there are multiple ways in which the sliding member 42 can be anti-rotation relative to the mounting base 41 along the circumferential direction of the through hole 411. In one possible implementation, one of the outer peripheral wall of the sliding member 42 and the inner peripheral 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 disposed in the groove 4111 along the first direction.

[0141] Since the protrusion 421 is slidably disposed in the groove 4111 along the first direction, the cooperation between the protrusion 421 and the groove 4111 can play a role in preventing rotation, thereby preventing the sliding member 42 from rotating circumferentially along the through hole 411.

[0142] Of course, the purpose of preventing the slider 42 from rotating 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 slider 42 can be a quadrangular prism and the through hole 411 can be a rectangular hole. In this way, the purpose of preventing the slider 42 from rotating relative to the mounting base 41 along the circumference of the through hole 411 can also be achieved under the cooperation of the rectangular hole and the quadrangular prism.

[0143] In some embodiments, see Figure 1 , Figure 4 and Figure 6 The indoor unit 100 of the air conditioner includes a front 13 and a side 14. A detachable housing 34 forms at least part of the front 13, and a water tank module 33 is detachably installed in the air conditioner housing 1 through the side 14.

[0144] That is, the detachable housing 34 and the water tank module 33 are located on two different sides of the air conditioner indoor unit 100. In this way, on the one hand, it can avoid interference between the detachable housing 34 and the water tank module 33. On the other hand, it can make the detachable housing 34 and the water tank module 33 located in two different 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, 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 interference between the sliding member 42 and the contact member 441 of the micro switch 44.

[0145] When the air conditioner casing 1 is rectangular, the aforementioned front 13 refers to the side of the air conditioner indoor unit 100 facing the user, and the aforementioned side 14 refers to the left and right sides of the air conditioner indoor unit 100.

[0146] In some embodiments, see Figure 17 , Figure 17 yes Figure 3 An exploded view of an air conditioner indoor unit 100, which also includes a fresh air module 5 disposed inside the air conditioner housing 1.

[0147] When the indoor unit 100 of the air conditioner also includes a fresh air module 5, the indoor unit 100 of the air conditioner can also integrate a fresh air function, making the function more diverse and the user experience better.

[0148] In some embodiments, see Figure 2, Figure 5 and Figure 17 The fresh air module 5 includes a fresh air volute 51 and a fresh air fan 52. The air conditioner housing 1 is provided with a fresh air inlet 15 and a fresh air outlet 16. The fresh air volute 51 is connected to both the fresh air inlet 15 and the fresh air outlet 16. The fresh air fan 52 is disposed inside the fresh air volute 51. The steam generator 32 has a steam outlet 321, which is connected to the fresh air outlet 16.

[0149] Since the fresh air volute 51 is connected to the fresh air inlet 15 and the fresh air outlet 16 respectively, and the fresh air fan 52 is installed inside the fresh air volute 51, when the fresh air fan 52 starts to operate, it can draw outdoor fresh air into the fresh air volute 51 through the fresh air inlet 15 for filtration, and blow the filtered fresh air into the room through the fresh air outlet 16, thereby achieving the purpose of improving indoor air quality.

[0150] Since the steam generator 32 has a steam outlet 321 that is connected to the fresh air outlet 16, the steam generated by the steam generator 32 can reach the fresh air outlet 16 through the steam outlet 321 and mix with the fresh air at the fresh air outlet 16. In this way, on the one hand, the fresh air can be made more humid, and on the other hand, when the fresh air is blown out of the fresh air outlet 16, it can carry the steam to a farther place in the room, so that the farther places in the room can also be humidified, thereby further improving the user experience of the air conditioner indoor unit 100.

[0151] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
