Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] When an air conditioner is heating, the relative humidity of the indoor air decreases, resulting in a poor user experience. Therefore, humidifying the indoor air becomes necessary when the air conditioner is heating. Existing humidification solutions for air conditioners include ultrasonic humidification, wet film humidification, steam humidification, and waterless humidification. Steam humidification is widely used because it can disinfect and sterilize.

[0003] Currently, air conditioners with steam humidification function have two problems: first, users are prone to electric shock when cleaning or repairing the steam humidification component by disassembling the front panel; second, the electric heater inside the steam humidification component has a short lifespan.

[0004] Therefore, how to extend the life of electric heaters while reducing the risk of electric shock to users when cleaning or repairing steam humidification components is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] This application discloses an indoor air conditioning unit that can extend the life of the electric heater while reducing the risk of electric shock to users when cleaning or repairing the steam humidification component.

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

[0007] The housing includes:

[0008] The shell body has an installation cavity inside it;

[0009] The front panel is detachably connected to the front side of the shell body;

[0010] Steam humidification components include:

[0011] A humidification box is located inside the main shell.

[0012] A water storage module is movably disposed within the mounting cavity to switch between an installation position and a water filling position. When the water storage module is in the installation position, the water storage module can be connected to the humidification box.

[0013] An electric heater is installed inside the humidification box;

[0014] A control switch for turning the electric heater on or off;

[0015] A trigger element is movably connected to the housing body and is capable of moving towards or away from the control switch;

[0016] The front panel is pressed against the trigger, and the water storage module is pressed against the trigger when it is in the installation position. The trigger is configured to press the control switch to turn on the electric heater under the combined pressure of the front panel and the water storage module.

[0017] When the front panel separates from the housing body and / or when the water storage module leaves the installation position, at least a portion of the trigger is released, resetting the control switch to shut off the electric heater.

[0018] In this application, the control switch is used to turn the electric heater on or off. When the front panel is connected to the main body and the water storage module is in the installation position, the front panel and the water storage module together press the trigger, causing the trigger to press the control switch to turn on the electric heater and perform steam humidification. When the user removes the front panel from the main body to clean or repair the humidifier, the front panel releases the trigger, resetting the control switch to turn off the electric heater. At this time, the power supply to the electric heater is cut off, thus solving the problem of electric shock caused by leakage from the electric heater. When the user switches the water storage module to the water filling position to add water to the water storage module, the water storage module leaves the installation position and releases the trigger, resetting the control switch to turn off the electric heater. At this time, the power supply to the electric heater is cut off, thus solving the problem of shortened lifespan of the electric heater due to prolonged dry burning.

[0019] It is evident that this application can extend the lifespan of the electric heater while reducing the risk of electric shock to users when cleaning or repairing the steam humidification components.

[0020] In one alternative embodiment, the trigger is movable relative to the housing body along a first direction, and the trigger and the control switch are disposed opposite each other along the first direction.

[0021] In this embodiment, the trigger can move relative to the housing body along a first direction to approach or move away from the control switch, thereby pressing or releasing the control switch and turning the electric heater on or off. The movable trigger can be designed as a more compact straight path to avoid invalid strokes caused by the rotation angle conversion of the rotating trigger, such as the swing range of the trigger. This can make the pressing and releasing of the control switch faster and the response time shorter.

[0022] In one alternative embodiment, the trigger includes:

[0023] A rotating shaft is rotatably connected to the shell body, and the rotating shaft and the shell body are slidably engaged along the first direction;

[0024] The first abutment part is located on one side of the straight line where the axis of the rotating shaft is located, and the first abutment part is in pressure contact with the front panel;

[0025] The second abutment part is located on the other side of the straight line where the axis of the rotating shaft is located, and the second abutment part is in extrusive contact with the water storage module located at the installation position;

[0026] When the water storage module leaves the installation position, the front panel presses against the trigger, causing the trigger to rotate relative to the shell body; when the water storage module is in the installation position and the front panel is separated from the shell body, the water storage module presses against the trigger, causing the trigger to rotate relative to the shell body.

[0027] The trigger is configured to move along the first direction under the combined pressure of the front panel and the water storage module to press the control switch.

[0028] When the water storage module is removed from its installation position and the front panel is separated from the main body, the first abutment portion corresponds to the front panel, and the second abutment portion corresponds to the water storage module. If the front panel is installed first, followed by the water storage module, the first abutment portion will be pressed down first, causing the second abutment portion to swing and tilt upwards. However, the swing amplitude of the second abutment portion is small, so it will still correspond to the water storage module. Therefore, when the water storage module is installed later, it can also press against the second abutment portion, causing the trigger to move and press the control switch. Similarly, if the water storage module is installed first, followed by the front panel, the front panel will also press against the first abutment portion, causing the trigger to move and press the control switch. It is evident that the structure of this embodiment does not restrict the installation order of the front panel and the water storage module, thereby simplifying the installation of the front panel and the water storage module.

[0029] In one optional embodiment, the rotation axis of the trigger extends along the height direction of the housing, the front panel is capable of applying a first compressive force to the trigger parallel to the depth direction of the housing, and the water storage module is capable of applying a second compressive force to the trigger parallel to the width direction of the housing.

[0030] The resultant force of the first extrusion force and the second extrusion force is parallel to the first direction.

[0031] In this embodiment, the resultant force direction of the first and second extrusion forces is consistent with the first direction. That is, the resultant force direction is consistent with the movement direction of the trigger element. Thus, the first and second extrusion forces applied to the trigger element are entirely converted into effective power to drive the trigger element to move along the first direction, reducing energy loss. Furthermore, since the resultant force direction is entirely used to drive linear motion without any lateral component, the rotating shaft will not exert pressure or friction on the housing body, thereby improving the smoothness of the trigger element's movement, reducing wear on the trigger element, and extending the service life of the trigger element.

[0032] In an optional embodiment, when the front panel is separated from the housing body and the water storage module leaves the installation position, the trigger can move to the initial position along the first direction, and the housing body includes:

[0033] A stop portion having a stop plane perpendicular to the first direction;

[0034] The trigger has a mating plane parallel to the stop plane. When the trigger is in the initial position, the stop plane contacts the mating plane to restrict the trigger from moving away from the control switch.

[0035] In this embodiment, when the trigger moves to the initial position along the first direction, the stop portion stops and limits the trigger in the direction away from the control switch, and the stop plane of the stop portion contacts the mating plane of the trigger. The plane contact can limit the rotation of the trigger. In this way, when the user accidentally touches the first abutment portion or the second abutment portion, the trigger is not easy to rotate relative to the shell body, so that the trigger is kept in the preset position, thereby ensuring that the stroke start point of the trigger is consistent each time the front panel or water storage module squeezes the trigger, improving the consistency and reliability of product performance.

[0036] In one alternative embodiment, the shell body includes:

[0037] The first bracket mates with the front panel to form the mounting cavity;

[0038] The second bracket is connected to the first bracket, and the second bracket and the first bracket cooperate to form a receiving space, and the trigger is disposed in the receiving space.

[0039] In this embodiment, the trigger is located within the receiving space formed by the cooperation of the first bracket and the second bracket. In this way, the first bracket and the second bracket can protect the trigger, prevent dust and other impurities from adhering to the trigger, and ensure the smooth sliding of the trigger relative to the shell body.

[0040] In one optional embodiment, the rotating shaft extends along the height direction of the housing, and the housing body includes:

[0041] A third support is provided within the accommodating space, and the third support is provided with a guide groove extending along the first direction, and the rotating shaft is movably provided within the guide groove;

[0042] The guide groove is configured to allow the shaft to rotate about its own axis and to allow the shaft to slide along the first direction.

[0043] In this embodiment, the guide groove extends along the first direction, and a portion of the rotating shaft is located within the guide groove. When the water storage module is in the installation position and the front panel is separated from the shell body, the rotating shaft rotates within the guide groove. When the water storage module leaves the installation position and the front panel is connected to the shell body, the rotating shaft rotates within the guide groove. When the water storage module is in the installation position and the front panel is connected to the shell body, the rotating shaft slides within the guide groove along the first direction. The inner wall of the guide groove can limit the rotation shaft, ensuring the stability of the trigger element moving along the first direction.

[0044] In one optional embodiment, the shell body is provided with mounting openings distributed along the width direction of the shell, the mounting openings communicating with the mounting cavity, and the water storage module includes:

[0045] A water tank cover is rotatably disposed within the mounting cavity to allow the water storage module to switch between the mounting position and the water filling position. The rotation axis of the water tank cover extends along the depth direction of the housing.

[0046] A water storage tank is detachably mounted on the water tank cover;

[0047] When the water storage module is in the installation position, the water storage tank can be connected to the humidification box, and the water tank cover is in contact with the trigger.

[0048] The process of adding water to the water tank in this embodiment is as follows: the water tank cover is rotated out of the mounting cavity. At this time, the opening of the water tank cover is outside the mounting cavity, that is, the opening of the water tank cover is no longer blocked by the shell body. The user can take the water tank out of the water tank cover through the opening so that the water tank can be taken to the water source to add water.

[0049] In an optional embodiment, the indoor unit of the air conditioner further includes:

[0050] An elastic reset element is disposed between the housing body and the trigger element to drive the trigger element to move in a direction away from the control switch.

[0051] In this embodiment, an elastic element is provided between the shell body and the trigger. Under the combined compression of the front panel and the water storage module, the trigger can move towards the control switch, causing the elastic reset element to be in a deformed state. When the front panel separates from the shell body and / or when the water storage module leaves the installation position, the elastic reset element can restore its elastic deformation, thereby causing the trigger to quickly move away from the control switch, resetting the control switch and turning off the electric heater. Therefore, the elastic reset element in this embodiment improves the sensitivity of the trigger in releasing the control switch.

[0052] In one optional embodiment, the humidification chamber is provided with a steam outlet, and the shell body contains:

[0053] The fresh air duct is connected to the steam outlet;

[0054] The indoor unit of the air conditioner also includes:

[0055] A fresh air fan is installed inside the fresh air duct to introduce outdoor air into the fresh air duct and exhaust it into the indoor space.

[0056] In this embodiment, the steam outlet is connected to the fresh air duct, which means that the steam generated in the humidification box can be transported to the fresh air duct and mixed with the fresh air. Since the temperature of the fresh air is lower than that of the steam, the mixing of fresh air and steam can reduce the temperature of the steam, thereby reducing the risk of steam burns to users.

[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0078] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0079] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0080] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0081] When an air conditioner is heating, the relative humidity of the indoor air decreases, resulting in a poor user experience. Therefore, humidifying the indoor air becomes necessary when the air conditioner is heating. Existing humidification solutions for air conditioners include ultrasonic humidification, wet film humidification, steam humidification, and waterless humidification. Steam humidification is widely used because it can disinfect and sterilize.

[0082] The inventors discovered that current air conditioners with steam humidification functions all use steam humidification components to generate steam. The steam humidification components include a humidification box and a water storage module that are connected to each other. The water storage module can replenish the humidification water for the humidification box. An electric heater is installed inside the humidification box. The electric heater evaporates the water in the humidification box, thereby generating steam.

[0083] When steam is generated inside the humidifier, the temperature inside is high, making it prone to condensation on the outer surface. If the electric heater leaks electricity while the user is cleaning the humidifier, it could cause electric shock. Furthermore, when the water level in the humidifier is low and the user removes the water storage module to add water, the electric heater remains operational, and the steam humidification component continues to generate steam. If the user removes the water storage module for an extended period, the electric heater will burn out the water in the humidifier and remain in a dry-burning state for a prolonged time, which obviously shortens the lifespan of the electric heater.

[0084] The air conditioning indoor unit provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0085] like Figures 1 to 9 As shown in the figure, this application discloses an indoor unit for an air conditioner, including:

[0086] Housing 100, comprising:

[0087] The housing body 110 has an installation cavity 101 inside. For example, the housing body 110 has a receiving space that can accommodate the steam humidification component 200 described below, and the receiving space includes the installation cavity 101; furthermore, the receiving space can also accommodate components such as an indoor heat exchanger, a fan, and a controller, etc., which are not limited in this application.

[0088] The front panel 120 is detachably connected to the front side of the housing body 110. For example, the front panel 120 can be connected to the housing body 110 via clips, screws, or other structures. It should be noted that the front side of the housing body 110 is the side of the housing body 110 closest to the user when the indoor unit of the air conditioner is in normal use.

[0089] Steam humidification unit 200, including:

[0090] Humidifier 210 is located inside shell 110. Humidifier 210 is used to contain humidification water and is the place where steam is generated.

[0091] The water storage module 220 is movably disposed within the mounting cavity 101 to switch between an installation position and a water filling position. When the water storage module 220 is in the installation position, it can communicate with the humidification box 210. For example, the water storage module 220 can be rotatably connected to the mounting cavity 101 to rotate relative to it; or, the water storage module 220 can be slidably connected to the mounting cavity 101 to move relative to it; or, the water storage module 220 may simply be housed within the mounting cavity 101 without any connection between them, thus allowing the water storage module 220 to be installed into or removed from the mounting cavity 101.

[0092] It should be noted that when the water storage module 220 is in the water filling position, at least a portion of the water storage module 220 is located outside the mounting cavity 101, so that the user can add water to the water storage module 220.

[0093] An electric heater (not shown in the figure) is installed inside the humidification chamber 210. The electric heater is used to heat and evaporate the humidification water inside the humidification chamber 210 to generate steam.

[0094] A control switch 300 is used to turn the electric heater on or off. Exemplarily, the control switch 300 can be communicatively connected to the electric heater to control its on / off state. The control switch 300 can be a tactile switch, micro switch, conductive rubber switch, etc., and this application does not limit the type of control switch 300. The control switch 300 can be located inside or outside the housing body 110.

[0095] The trigger 400 is movably connected to the housing body 110 and is movable in a direction toward or away from the control switch 300. For example, the trigger 400 may be rotatably or slidably connected to the housing body 110, allowing it to rotate or slide relative to the housing body 110. The trigger 400 may be located inside or outside the housing body 110.

[0096] The front panel 120 is pressed into contact with the trigger 400. That is, when the air conditioner is in normal use, the front panel 120 is connected to the housing body 110. At this time, the front panel 120 is pressed into contact with the trigger 400. The water storage module 220 is pressed into contact with the trigger 400 when it is in the installation position. The trigger 400 is configured to press the control switch 300 to turn on the electric heater under the joint pressure of the front panel 120 and the water storage module 220.

[0097] At least a portion of the trigger 400 is released when the front panel 120 separates from the housing body 110 and / or when the water storage module 220 leaves the installation position, resetting the control switch 300 to turn off the electric heater. That is, when the front panel 120 separates from the housing body 110, the front panel 120 releases the trigger 400, resetting the control switch 300; when the water storage module 220 leaves the installation position, the water storage module 220 releases the trigger 400, resetting the control switch 300. Therefore, the trigger 400 will be released and the control switch 300 will reset whenever either of these two situations occurs: the front panel 120 separates from the housing body 110, or the water storage module 220 leaves the installation position.

[0098] In this application, the control switch 300 is used to turn the electric heater on or off. When the front panel 120 is connected to the housing body 110 and the water storage module 220 is in the installation position, the front panel 120 and the water storage module 220 together press the trigger 400, causing the trigger 400 to press the control switch 300 to turn on the electric heater and perform steam humidification. When the user removes the front panel 120 from the housing body 110 to clean or repair the humidification box 210, the front panel 120 releases the trigger 400, causing the control switch 300 to reset and turn off the electric heater. At this time, the power supply to the electric heater is cut off, thereby solving the problem of electric shock to the user due to leakage of the electric heater. When the user switches the water storage module 220 to the water filling position to add water to the water storage module 220, the water storage module 220 will leave the installation position and release the trigger 400, causing the control switch 300 to reset and turn off the electric heater. At this time, the power supply to the electric heater is cut off, thereby solving the problem of the electric heater's lifespan being shortened due to the electric heater being in a dry-burning state for a long time.

[0099] It is evident that this application can extend the lifespan of the electric heater while reducing the risk of electric shock to users when cleaning or repairing the steam humidification components.

[0100] Please see Figure 5 In an alternative embodiment, the trigger 400 is capable of being positioned relative to the shell body 110 along a first direction ( Figure 5 and Figure 9 The trigger 400 and the control switch 300 are positioned relative to each other in the first direction (as indicated by the arrow in the middle).

[0101] In this embodiment, the trigger 400 can move relative to the housing body 110 along a first direction to approach or move away from the control switch 300, thereby pressing or releasing the control switch 300 and turning the electric heater on or off. The movable trigger 400 can be designed with a more compact straight path to avoid invalid travel caused by the rotation angle change of the rotating trigger 400, such as the swing range of the trigger 400. This allows the pressing and releasing of the control switch 300 to be faster and the response time to be shorter. It should be noted that when the trigger 400 releases the control switch 300, the control switch 300 will reset, thereby turning off the electric heater.

[0102] In some embodiments, the trigger 400 can only move relative to the shell body 110 in a first direction and cannot rotate relative to the shell body 110. At this time, the front panel 120 is provided with a first extrusion part 121 with elasticity, which can press against the trigger 400. The water storage module 220 is provided with a second extrusion part 223 with elasticity, which can press against the trigger 400.

[0103] Under the combined pressure of the first extrusion part 121 and the second extrusion part 223, the trigger member 400 moves to the trigger position; when the front panel 120 separates from the shell body 110 and the water storage module 220 leaves the installation position, the trigger member 400 moves to the initial position; when either the front panel 120 separates from the shell body 110 or the water storage module 220 leaves the installation position, the trigger member 400 moves between the trigger position and the initial position.

[0104] However, when using this embodiment, the trigger 400 in the initial position corresponds either to the first pressing part 121 or the second pressing part 223, which requires a specific installation order for the front panel 120 and the water storage module 220. For example, when the trigger 400 in the initial position corresponds to the first pressing part 121, the front panel 120 must be installed first, followed by the water storage module 220; when the trigger 400 in the initial position corresponds to the second pressing part 223, the water storage module 220 must be installed first, followed by the front panel 120.

[0105] Please see Figures 5 to 9 In one alternative embodiment, the trigger 400 includes:

[0106] The rotating shaft 410 is rotatably connected to the housing body 110, and the rotating shaft 410 and the housing body 110 are slidably engaged in a first direction. The trigger member 400 can rotate relative to the housing body 110 via the rotating shaft 410, and can also move relative to the housing body 110 in a first direction via the rotating shaft 410.

[0107] The first abutment portion 420 is located on one side of the straight line of the axis of the rotating shaft 410. The first abutment portion 420 is in pressure contact with the front panel 120. That is, when the front panel 120 is connected to the shell body 110, the first abutment portion 420 is in pressure contact with the front panel 120. Specifically, the front panel 120 is provided with a first pressing portion 121, which can press the first abutment portion 420. The first pressing portion 121 can be a rigid structural component.

[0108] The second abutment portion 430 is located on the other side of the axis of the rotating shaft 410, and the second abutment portion 430 makes pressure contact with the water storage module 220 located in the installation position. Specifically, the water storage module 220 is provided with a second extrusion portion 223, which can extrude the second abutment portion 430. The second extrusion portion 223 can be a rigid structural component.

[0109] When the water storage module 220 leaves the installation position, the front panel 120 presses the trigger 400, causing the trigger 400 to rotate relative to the shell body 110; when the water storage module 220 is in the installation position and the front panel 120 is separated from the shell body 110, the water storage module 220 presses the trigger 400, causing the trigger 400 to rotate relative to the shell body 110.

[0110] The trigger 400 is configured to move in a first direction under the combined pressure of the front panel 120 and the water storage module 220 to press the control switch 300.

[0111] The movement process of the trigger 400 in this embodiment is as follows: when the water storage module 220 leaves the installation position and the front panel 120 is connected to the shell body 110, the front panel 120 presses against the first abutment part 420, the water storage module 220 releases the second abutment part 430, causing one end of the trigger 400 with the second abutment part 430 to swing around the pivot 410 in a direction away from the control switch 300 and tilt upwards. Figure 8 (As shown in the figure) At this time, the trigger 400 will not press or will not fully press down the control switch 300, and the electric heater is in the off state.

[0112] When the water storage module 220 is in the installation position and the front panel 120 is separated from the housing body 110, the front panel 120 releases the first abutment portion 420, and the water storage module 220 presses against the second abutment portion 430, causing the trigger member 400 with the first abutment portion 420 to swing around the pivot 410 in a direction away from the control switch 300 and tilt upwards. Figure 7 (As shown in the figure) At this time, the trigger 400 will not press or will not fully press down the control switch 300, and the electric heater is in the off state.

[0113] When the water storage module 220 is in the installation position and the front panel 120 is connected to the shell body 110, the front panel 120 is pressed into contact with the first abutment part 420 and the water storage module 220 is pressed into contact with the second abutment part 430, thereby driving the trigger 400 to approach and press the control switch 300 in the first direction, thereby turning on the electric heater.

[0114] When the water storage module 220 leaves its installation position and the front panel 120 separates from the housing body 110, the front panel 120 releases the first abutment part 420, the water storage module 220 releases the second abutment part 430, and the trigger 400 will not press the control switch 300. Figure 6 (As shown in the diagram), the electric heater is in the off state.

[0115] When the water storage module 220 is removed from its installation position and the front panel 120 is separated from the housing body 110, the first abutment portion 420 is positioned corresponding to the front panel 120, and the second abutment portion 430 is positioned corresponding to the water storage module 220. If the front panel 120 is installed first, followed by the water storage module 220, the first abutment portion 420 will be pressed first, causing the second abutment portion 430 to swing and tilt upwards. However, the swing amplitude of the second abutment portion 430 is small, so the second abutment portion 430 will still correspond to the water storage module 220. Therefore, when the water storage module 220 is installed later, it can also press against the second abutment portion 430, causing the trigger member 400 to move and press the control switch 300. Similarly, if the water storage module 220 is installed first, followed by the front panel 120, the front panel 120 will also press against the first abutment portion 420, causing the trigger member 400 to move and press the control switch 300. As can be seen, the structure of this embodiment does not restrict the installation order of the front panel 120 and the water storage module 220, thereby simplifying the installation of the front panel 120 and the water storage module 220.

[0116] Please see Figure 9 In one optional embodiment, the rotation axis of the trigger 400 is along the height direction of the housing 100. Figure 2 Extending in the direction indicated by the arrow in the middle (z), the front panel 120 can apply pressure to the trigger 400 in a depth direction parallel to the housing 100 (…). Figure 2 The first compressive force (in the direction indicated by the arrow in the middle) (by...) Figure 9 As shown in F1, the water storage module 220 can apply a force to the trigger 400 in a width direction parallel to the housing 100. Figure 2 The second compressive force (in the direction indicated by the x-arrow line) (by...) Figure 9 (As shown in F2).

[0117] The resultant force of the first and second extrusion forces is parallel to the first direction. It should be noted that the resultant force of the first and second extrusion forces is... Figure 9F3 is shown in the diagram.

[0118] In this embodiment, the resultant force direction of the first and second extrusion forces is consistent with the first direction, that is, the resultant force direction is consistent with the movement direction of the trigger 400. Thus, the first and second extrusion forces applied to the trigger 400 are entirely converted into effective power to drive the trigger 400 to move along the first direction, reducing energy loss. Furthermore, since the resultant force is entirely used to drive linear motion without any lateral component, the rotating shaft 410 will not exert pressure or friction on the housing body 110, thereby improving the smoothness of the trigger 400's movement, reducing wear on the trigger 400, and extending the service life of the trigger 400. Of course, the resultant force direction of the first and second extrusion forces can also be inclined relative to the first direction; this application does not limit this.

[0119] Please see Figure 6 , Figures 10 to 12 In an optional embodiment, when the front panel 120 separates from the housing body 110 and the water storage module 220 leaves the installation position, the trigger 400 can move to the initial position along the first direction. Figure 6 and Figure 12 (as shown in the image), the shell body 110 includes:

[0120] The stop portion 111 has a stop plane 102 perpendicular to the first direction.

[0121] The trigger 400 has a mating plane 401 parallel to the stop plane 102. When the trigger 400 is in the initial position, the stop plane 102 is in contact with the mating plane 401 to restrict the trigger 400 from moving away from the control switch 300.

[0122] In this embodiment, when the trigger 400 moves to the initial position along the first direction, the stop portion 111 stops and limits the trigger 400 in the direction away from the control switch 300, and the stop plane 102 of the stop portion 111 is in contact with the mating plane 401 of the trigger 400. The plane contact can restrict the rotation of the trigger 400. In this way, when the user accidentally touches the first abutment portion 420 or the second abutment portion 430, the trigger 400 is less likely to rotate relative to the shell body 110, so that the trigger 400 is kept in the preset position. This ensures that the starting point of the stroke of the front panel 120 or the water storage module 220 is consistent each time the trigger 400 is pressed, thereby improving the consistency and reliability of product performance. Of course, the stop portion 111 may not be in contact with the trigger 400; or the shell body 110 may not include the stop portion 111. This application does not limit this.

[0123] Please see Figure 4 and Figure 5 In one alternative embodiment, the shell body 110 includes:

[0124] The first bracket 112, together with the front panel 120, forms a mounting cavity 101.

[0125] The second bracket 113 is connected to the first bracket 112. The second bracket 113 and the first bracket 112 cooperate to form a receiving space 103, and the trigger 400 is disposed in the receiving space 103.

[0126] In this embodiment, the trigger 400 is located in the receiving space 103 formed by the cooperation of the first bracket 112 and the second bracket 113. In this way, the first bracket 112 and the second bracket 113 can protect the trigger 400, prevent dust and other impurities from adhering to the trigger 400, and ensure the smooth sliding of the trigger 400 relative to the shell body 110.

[0127] It should be noted that the first bracket 112 is provided with a first clearance hole connecting the receiving space 103 and the mounting cavity 101, and the first abutting part 420 passes through the first clearance hole; the second bracket 113 is provided with a second clearance hole, and the second abutting part 430 passes through the second clearance hole, so that the second abutting part 430 is exposed to the front panel 120 so that it can be pressed by the front panel 120.

[0128] Please see Figure 5 In one optional embodiment, the pivot 410 extends along the height direction of the housing 100, and the housing body 110 includes:

[0129] A third bracket 114 is disposed within the receiving space 103. The third bracket 114 is provided with a guide groove 104 extending along a first direction, and the rotating shaft 410 is movably disposed within the guide groove 104. For example, the third bracket 114 can limit the position of the trigger 400 along the height direction of the housing.

[0130] The guide groove 104 is configured to allow the shaft 410 to rotate about its own axis and to allow the shaft 410 to slide in a first direction.

[0131] In this embodiment, the guide groove 104 extends along the first direction, and a portion of the rotating shaft 410 is located within the guide groove 104. When the water storage module 220 is in the installation position and the front panel 120 is separated from the shell body 110, the rotating shaft 410 rotates within the guide groove 104. When the water storage module 220 leaves the installation position and the front panel 120 is connected to the shell body 110, the rotating shaft 410 rotates within the guide groove 104. When the water storage module 220 is in the installation position and the front panel 120 is connected to the shell body 110, the rotating shaft 410 slides within the guide groove 104 along the first direction. The inner wall of the guide groove 104 can limit the rotating shaft 410, ensuring the stability of the trigger 400 moving along the first direction.

[0132] Please see Figure 2 and Figure 3 In one optional embodiment, the shell body 110 is provided with mounting openings distributed along the width direction of the shell 100, the mounting openings communicating with the mounting cavity 101, and the water storage module 220 includes:

[0133] A water tank cover 221 is rotatably disposed within the mounting cavity 101 to allow the water storage module 220 to switch between an installation position and a water filling position. The rotation axis of the water tank cover 221 extends along the depth direction of the housing 100. Exemplarily, the water tank cover 221 here has an opening to facilitate the insertion or removal of the water storage tank 222 from the water tank cover 221.

[0134] The water storage tank 222 is detachably mounted on the water tank cover 221, so that the water storage tank 222 can be removed from the water tank cover 221, making it convenient for users to add water to the water storage tank 222.

[0135] When the water storage module 220 is in the installation position, the water storage tank 222 can be connected to the humidification box 210, and the water tank cover 221 is in contact with the trigger 400.

[0136] The process of adding water to the water storage tank 222 in this embodiment is as follows: the water tank cover 221 is rotated out of the mounting cavity 101. At this time, the opening of the water tank cover 221 is outside the mounting cavity 101, that is, the opening of the water tank cover 221 is no longer blocked by the shell body 110. The user can take the water storage tank 222 out of the water tank cover 221 through the opening so that the water storage tank 222 can be taken to the water source to add water.

[0137] Of course, in some other embodiments, the water storage module 220 may only include the water storage tank 222 without the water tank cover 221. In this case, when the water storage module 220 is in the installation position, the water storage tank 222 can be connected to the humidification box 210 and press against the trigger 400.

[0138] In a further embodiment, the first end of the water tank cover 221 is provided with a rotating part, which is rotatably connected to the shell body 110. The second end of the water tank cover 221 is provided with a second pressing part 223 for pressing the second abutment part 430. This embodiment allows the rotation axis of the water tank cover 221 to be set away from the second pressing part 223, thereby allowing the second abutment part 430 to be released with a smaller rotation angle of the water tank cover 221, improving sensitivity.

[0139] Please see Figure 12 In one optional embodiment, the indoor unit of the air conditioner further includes:

[0140] An elastic reset member 500 is disposed between the housing body 110 and the trigger member 400 to drive the trigger member 400 to move in a direction away from the control switch 300. Exemplarily, the elastic reset member 500 can be a spring, a sheet, an elastic cord, etc., and this application does not limit this to such applications.

[0141] In this embodiment, an elastic element is provided between the housing body 110 and the trigger 400. Under the combined compression of the front panel 120 and the water storage module 220, the trigger 400 can move towards the control switch 300, so that the elastic reset element 500 is in a deformed state. When the front panel 120 separates from the housing body 110 and / or when the water storage module 220 leaves the installation position, the elastic reset element 500 can restore its elastic deformation, thereby driving the trigger 400 to quickly move away from the control switch 300, so that the control switch 300 is reset and the electric heater is turned off. It can be seen that the elastic reset element 500 in this embodiment can improve the sensitivity of the trigger 400 in releasing the control switch 300. Of course, in addition to the elastic reset element 500 in this embodiment, the trigger 400 can also be reset by the elastic element in the control switch 300, and this application does not limit this.

[0142] In one optional embodiment, the humidification chamber 210 is provided with a steam outlet, and the outer casing contains:

[0143] The fresh air duct is connected to the steam outlet. Specifically, this fresh air duct connects the outdoor and indoor spaces, allowing the air conditioner to deliver fresh outdoor air into the indoor space.

[0144] The indoor unit of the air conditioner also includes:

[0145] A fresh air fan, located inside a fresh air duct, is used to introduce outdoor air into the fresh air duct and exhaust it into the indoor space.

[0146] In this embodiment, the steam outlet is connected to the fresh air duct, which means that the steam generated in the humidification box 210 can be transported to the fresh air duct and mixed with the fresh air. Since the temperature of the fresh air is lower than that of the steam, the mixing of the fresh air and the steam can reduce the temperature of the steam, thereby reducing the risk of steam burns to users.

[0147] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
