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] An air conditioner includes an indoor unit located in an indoor environment and an outdoor unit located in an outdoor environment. The indoor unit works in conjunction with the outdoor unit to regulate the temperature, humidity, airflow, or cleanliness of the air in the indoor environment.

[0003] To regulate indoor air humidity, air conditioner indoor units can be equipped with humidifiers. These humidifiers heat liquid to generate a humidifying fluid, which is then expelled from the indoor unit with airflow, achieving the humidification effect. When the indoor unit is not in use for extended periods, the humidifier can also use a self-cleaning function to heat and evaporate the liquid inside, preventing it from spoiling and developing an unpleasant odor.

[0004] However, the humidifier takes a long time to dry the liquid, resulting in high energy consumption. Utility Model Content

[0005] This application discloses an indoor air conditioning unit that can shorten the time for the liquid to evaporate in the self-cleaning mode and reduce energy consumption.

[0006] To achieve the above objectives, this application discloses an indoor air conditioning unit, comprising: a housing and a humidifying device. The housing has an air outlet, and the humidifying device is disposed on the housing and is used to generate humidifying fluid and discharge the humidifying fluid from the housing through the air outlet. The humidifying device includes a liquid supply component, a one-way valve, and a heating assembly. The liquid supply component has a liquid supply chamber and a liquid outlet. The liquid supply chamber is used to store liquid, and the liquid outlet is connected to the bottom of the liquid supply chamber. The one-way valve is disposed on the liquid supply component and configured to switch between a closed state and an open state. When the one-way valve is in the closed state, it closes the liquid outlet to prevent liquid in the liquid supply component from flowing out through the liquid outlet. The heating assembly includes a liquid storage component and a driving unit. The liquid storage component has a humidifying chamber and a mounting chamber inside. The humidifying chamber is used to receive the liquid flowing out from the liquid outlet. The system heats the liquid to generate humidifying fluid. The drive unit includes a motor, a drive component, and a transmission component. The motor is located in the mounting cavity, the drive component is located on the output shaft of the motor, and the transmission component is rotatably mounted on the liquid storage component. The first end of the transmission component is located in the mounting cavity, and the second end of the transmission component extends into the humidification cavity and can contact the one-way valve. The rotation axis of the transmission component is located between the first end and the second end of the transmission component. The drive component is configured to drive the first end of the transmission component to rotate around the rotation axis under the drive of the motor, so that the second end of the transmission component moves to the trigger position where it contacts the one-way valve, or moves to the disengagement position where it is no longer in contact with the one-way valve. When the transmission component is in the trigger position, the transmission component abuts against the one-way valve and puts the one-way valve in the open state, so that the liquid supply component supplies liquid to the humidification cavity.

[0007] With the above settings, during the humidification process of the indoor unit of the air conditioner, the drive unit can control the one-way valve to switch between the open and closed states, so as to control the liquid supply component to supply liquid to the liquid storage component more accurately, thereby controlling the liquid level in the liquid storage component more accurately and ensuring the humidification effect.

[0008] When the indoor unit of the air conditioner has not been used for a long time, the humidification function can be activated in self-cleaning mode. The heating element can heat and evaporate the liquid in the humidification chamber to prevent the liquid in the humidification chamber from becoming contaminated and growing mold or bacteria and other microorganisms, which would cause it to deteriorate and smell bad if it has not been used for a long time.

[0009] During the self-cleaning process of the indoor unit of the air conditioner, the drive unit can control the one-way valve to switch to the closed state to prevent the liquid supply component from supplying liquid to the liquid storage component, so that the heating component only evaporates the liquid in the humidification chamber. This avoids the liquid in the liquid supply component from being evaporated as well, and shortens the time required for the self-cleaning function of the humidification device to evaporate the liquid in the humidification chamber, thereby reducing the energy consumption of the indoor unit of the air conditioner.

[0010] Furthermore, the transmission components, driven by the motor and drive components, switch the one-way valve between the open and closed states. The one-way valve and the liquid supply component do not directly contact the motor and are not connected to the circuit, thus avoiding the one-way valve and the liquid supply component from becoming electrified. Users are not at risk of electric shock when adding water to the humidifier, which facilitates user operation, improves the safety of the indoor air conditioning unit, and enhances the user experience.

[0011] Meanwhile, the motor is located in the mounting cavity rather than the humidification cavity, which helps to prevent the motor from being damaged by water, reduces the risk of water and electricity leakage from the humidification device, and improves the safety and protection of the indoor unit of the air conditioner.

[0012] Optionally, the humidification chamber and the mounting chamber are arranged sequentially in the height direction of the humidification device, with the humidification chamber located above the mounting chamber.

[0013] The above settings prevent liquid from flowing into the installation cavity from the humidification chamber, reducing the risk of water damage to the motor and extending the service life of the humidification device.

[0014] Optionally, the top of the humidification chamber has an opening, and the opening and the mounting cavity are arranged in the height direction of the humidification device. The mounting cavity is closer to the bottom of the humidification device than the opening. The height of the first end and the second end of the transmission member are both lower than the height of the rotation axis, and the second end of the transmission member extends into the humidification chamber from the opening.

[0015] With the above settings, the liquid in the humidification chamber is less likely to flow out of the opening, thereby preventing liquid from flowing into the installation chamber, reducing the risk of the motor being damaged by water, and extending the service life of the humidification device.

[0016] Optionally, the transmission component includes a first connecting rod, a rotating part, and a second connecting rod connected in sequence. The rotating part is rotatably connected to the liquid storage component. The first end of the first connecting rod is connected to the rotating part. The second end of the first connecting rod is configured to rotate around the rotation axis under the drive of the driving component. The second end of the first connecting rod is closer to the bottom of the humidification device than the first end of the first connecting rod. The first end of the second connecting rod is connected to the rotating part. The second end of the second connecting rod can contact a one-way valve. The second end of the second connecting rod is closer to the bottom of the humidification device than the first end of the second connecting rod.

[0017] With the above configuration, the first connecting rod, the rotating part, and the second connecting rod are sequentially connected to form a transmission component, making the transmission component approximately "U"-shaped. The transmission component can be driven and connected to the motor within the mounting cavity, and extends from the mounting cavity towards the top of the humidification device to be rotatably connected to the top of the liquid storage component. It then extends into the humidification chamber through the opening and further extends to the one-way valve. Thus, the transmission component connects the motor and the one-way valve, enabling the motor to control the one-way valve to switch between open and closed states via the transmission component.

[0018] Optionally, the outlet is connected to the top of the check valve, and the second end of the second connecting rod has a top abutment that contacts the bottom of the check valve and is used to abut the check valve when the second connecting rod rotates, so that the check valve is in the open state.

[0019] With the above configuration, the transmission component can press against the one-way valve at the top, causing the one-way valve to change from a closed state to an open state, thereby allowing the liquid supply component to supply liquid to the humidification chamber through the liquid outlet.

[0020] Optionally, the first connecting rod includes a first extension section and a second extension section. The first extension section is connected to the rotating part, and the second extension section is connected to the side of the first extension section opposite to the rotating part. The second extension section is inclined relative to the first extension section and extends toward the driving member. The second end of the first connecting rod is located in the second extension section. The second connecting rod includes a third extension section and a bent section. The third extension section is connected to the rotating part, and the bent section is located on the side of the third extension section opposite to the rotating part. The bent section is bent relative to the third extension section to avoid the one-way valve when the transmission member rotates. The second end of the second connecting rod is located in the bent section.

[0021] With the above configuration, the second connecting rod can contact the valve core of the one-way valve through the bent section, thereby controlling the one-way valve to switch between the open and closed states. Furthermore, the bent section can avoid the one-way valve and the first housing when the transmission component rotates.

[0022] Optionally, the drive member has two drive arms, which are spaced apart in the circumferential direction of the motor output shaft. The second end of the first connecting rod is located between the two drive arms. The drive member is configured to reciprocate under the drive of the motor so that one of the two drive arms abuts against the first connecting rod and drives the first connecting rod to rotate around the rotation axis of the transmission member. When different drive arms abut against the first connecting rod, the first connecting rod has different rotation directions.

[0023] With the above settings, the motor can drive the transmission component to rotate in different directions through the drive component, so as to control the one-way valve to switch between the open and closed states.

[0024] Optionally, the humidification chamber includes a liquid storage chamber, a liquid seal channel, and a heating chamber. The liquid outlet is located in the liquid storage chamber, and the liquid seal channel connects the liquid storage chamber and the heating chamber. The heating chamber is used to heat the liquid to generate humidifying fluid. The highest liquid level in the liquid seal channel is configured to be lower than the highest liquid level in the heating chamber to prevent the humidifying fluid in the heating chamber from flowing out of the liquid seal channel.

[0025] With the above settings, when the liquid in the heating chamber is higher than the highest liquid level in the liquid seal channel, the liquid in the liquid seal channel can prevent the humidifying fluid in the heating chamber from leaking from the liquid seal channel and the opening.

[0026] Optionally, the one-way valve includes a seat, a valve core, and an elastic element. The seat is disposed on the liquid storage element and detachably connected to the liquid supply element. The seat has a through cavity that communicates between the liquid outlet and the humidification chamber. The valve core is movably disposed in the through cavity along a first direction to switch the one-way valve between a closed state and an open state. The valve core is configured to contact a transmission element to move along the first direction under the drive of the transmission element. The elastic element is located between the valve core and the seat and is configured to keep the one-way valve in a closed state by its own elastic force.

[0027] With the above settings, the valve core can move along the first direction to switch the check valve between the open and closed states.

[0028] Optionally, it also includes a fresh air device, which is located inside the housing and has a fresh air inlet connected to the air outlet. The fresh air device is configured to generate airflow towards the air outlet through the fresh air inlet, so as to drive the humidifying fluid generated by the humidifying device to be discharged through the air outlet.

[0029] With the above settings, as the airflow from the fresh air inlet flows towards the air outlet, the humidifier generates humidifying fluid, which is then discharged into the indoor environment through the air outlet under the influence of the airflow, thus achieving the humidification function.

[0050] As mentioned in the background section, an air conditioner includes an indoor unit located in an indoor environment and an outdoor unit located in an outdoor environment. The indoor unit works in conjunction with the outdoor unit to regulate parameters such as temperature, humidity, airflow rate, and cleanliness of the air in the indoor environment. To regulate the humidity of the indoor air, a humidifier can be installed in the indoor unit. The humidifier generates a humidifying fluid by heating a liquid, which is then discharged from the indoor unit with the airflow to achieve a humidification effect. When the indoor unit is idle for extended periods, the humidifier can also use a self-cleaning function to heat and evaporate the liquid inside to prevent it from spoiling and developing an odor. However, the humidifier takes a long time to evaporate the liquid, resulting in high energy consumption.

[0051] To address the aforementioned issues, this application provides an indoor air conditioning unit to solve the problem of high energy consumption caused by the long time required for humidification devices to evaporate liquid in related technologies.

[0052] The indoor unit of this application embodiment can be applied to at least one of wall-mounted, cabinet, or built-in air conditioners. The indoor unit can be installed in indoor environments such as residences, offices, shops, or computer rooms, while the outdoor unit, which is interconnected with and works in conjunction with the indoor unit, can be installed in an outdoor environment corresponding to the indoor environment, such as the exterior wall, roof, terrace, or ground of a building.

[0053] An air conditioner's indoor and outdoor units work together to regulate the temperature of the air in the indoor environment and to achieve cooling or heating functions. Alternatively, the indoor and outdoor units can also work together to regulate the humidity, airflow, or cleanliness of the air in the indoor environment.

[0054] In some examples, there may be one indoor unit and one outdoor unit. In other examples, there may be multiple indoor units. Accordingly, when there are multiple indoor units, the air conditioner used in the indoor unit provided in this application embodiment can be a central air conditioning system.

[0055] Please refer to Figures 1 to 6 The indoor unit of the air conditioner of this application includes a housing and a humidifying device 10. The humidifying device 10 is disposed inside the housing. The housing has an air outlet. The humidifying device 10 is used to generate humidifying fluid. The humidifying fluid can be discharged from the housing through the air outlet and enter the indoor environment, thereby regulating the humidity of the air in the indoor environment and realizing the humidification function.

[0056] The humidification device 10 includes a liquid supply component 100, a one-way valve 200, and a heating component 300. The liquid supply component 100 is used to supply liquid to the heating component 300, the one-way valve 200 is connected between the liquid supply component 100 and the heating component 300, and the heating component 300 is used to generate humidifying fluid.

[0057] The liquid supply unit 100 has a liquid supply chamber 110 and a liquid outlet 120. The liquid supply chamber 110 is used to store liquids such as pure water, distilled water or cooled boiled water. The liquid outlet 120 is connected to the bottom of the liquid supply chamber 110. The liquid in the liquid supply chamber 110 can flow out of the liquid supply chamber 110 through the liquid outlet 120 under the action of gravity.

[0058] A one-way valve 200 is provided on the liquid supply component 100 and can switch between a closed state and an open state. When the one-way valve 200 is in the closed state, it closes the outlet 120 to prevent liquid in the liquid supply component 100 from flowing out through the outlet 120. When the one-way valve 200 is in the open state, it opens the outlet 120, allowing liquid in the liquid supply component 100 to flow out through the outlet 120.

[0059] The heating assembly 300 includes a liquid storage unit 310 and a drive unit 330. The liquid storage unit 310 has a humidification chamber 311 and a mounting chamber 312 inside. The humidification chamber 311 is used to receive liquid flowing out of the liquid outlet 120 when the one-way valve 200 is in the open state. The humidification chamber 311 is also used to heat the liquid to generate humidifying fluid.

[0060] The drive unit 330 includes a motor 340, a drive component 350, and a transmission component 360. The motor 340 and the drive component 350 are disposed within the mounting cavity 312. The drive component 350 is mounted on the output shaft of the motor 340 and is drively connected between the motor 340 and the transmission component 360. The transmission component 360 is mounted on the liquid storage component 310 and is rotatably connected to the liquid storage component 310. The transmission component 360 has a first end and a second end, and the axis of rotation of the transmission component 360 is located between the first end and the second end of the transmission component 360. The first end of the transmission component 360 is located within the mounting cavity 312 and is drively connected to the drive component 350. The second end of the transmission component 360 extends into the humidification cavity 311 and can contact the one-way valve 200.

[0061] Therefore, the motor 340 can drive the drive component 350 to rotate, thereby causing the first end of the transmission component 360 to rotate around the rotation axis, and moving the second end of the transmission component 360 to the trigger position where it contacts the one-way valve 200. When the transmission component 360 is in the trigger position, it abuts against the one-way valve 200, so that the one-way valve 200 is in the open state, and the liquid supply component 100 supplies liquid to the humidification chamber 311.

[0062] Alternatively, the motor 340 can drive the drive component 350 to rotate, thereby causing the first end of the transmission component 360 to rotate around the rotation axis and moving the second end of the transmission component 360 to a disengaged position where it is no longer in contact with the one-way valve 200. When the transmission component 360 is in the disengaged position, it disengages from the one-way valve 200, causing the one-way valve 200 to be closed, and the liquid supply component 100 stops supplying liquid to the humidification chamber 311.

[0063] With the above settings, during the humidification process of the indoor unit of the air conditioner, the drive unit 330 can control the one-way valve 200 to switch between the open and closed states, so as to more accurately control the liquid supply component 100 to supply liquid to the liquid storage component 310, thereby more accurately controlling the liquid level in the liquid storage component 310 and ensuring the humidification effect.

[0064] When the indoor unit of the air conditioner has not been used for a long time, the humidification device 10 can start the self-cleaning mode. The heating component 300 can heat and dry the liquid in the humidification chamber 311 to prevent the liquid in the humidification chamber 311 from being contaminated and growing mold or bacteria and other microorganisms when it has not been used for a long time, which would cause it to deteriorate and smell bad.

[0065] During the self-cleaning process of the indoor unit of the air conditioner, the drive unit 330 can control the one-way valve 200 to switch to the closed state to prevent the liquid supply component 100 from supplying liquid to the liquid storage component 310, so that the heating component 300 only evaporates the liquid in the humidification chamber 311. This avoids the liquid in the liquid supply component 100 from being evaporated as well, and shortens the time required for the self-cleaning function of the humidification device 10 to evaporate the liquid in the humidification chamber 311, thereby reducing the energy consumption of the indoor unit of the air conditioner.

[0066] Furthermore, the transmission component 360, driven by the motor 340 and the drive component 350, drives the one-way valve 200 to switch between the open and closed states. The one-way valve 200 and the liquid supply component 100 do not directly contact the motor 340 and are not connected to the circuit, thus avoiding the one-way valve 200 and the liquid supply component 100 from being energized. There is no risk of electric shock when the user adds water to the humidifier 10, which facilitates user operation, improves the safety of the indoor unit of the air conditioner, and enhances the user experience.

[0067] Meanwhile, the motor 340 is located in the mounting cavity 312 instead of the humidification cavity 311, which helps to avoid damage to the motor 340 when it comes into contact with water, reduces the risk of water leakage and electric leakage of the humidification device 10, and improves the safety and protection effect of the indoor unit of the air conditioner.

[0068] The components and technical solutions of the air conditioner indoor unit of this application will be further described below with reference to specific embodiments and accompanying drawings. For ease of explanation, the height direction of the air conditioner indoor unit is defined as the first direction x. Correspondingly, the height direction of the humidification device 10 is parallel or approximately parallel to the first direction x.

[0069] The indoor unit of the air conditioner includes a casing (not shown in the figure), with its air outlet facing the indoor environment to facilitate the entry of airflow and humidifying fluid from inside the casing into the indoor environment. The indoor unit may also include a fresh air unit (not shown in the figure) installed within the casing, having a fresh air inlet communicating with the air outlet. The fresh air unit can treat fresh air from the outdoor environment and introduce it into the casing through the fresh air inlet, then blow the fresh air into the indoor environment through the air outlet to regulate the cleanliness of the indoor air.

[0070] The fresh air inlet can face the air outlet, allowing the airflow from the fresh air inlet to flow directly to the air outlet and be discharged from the air outlet. Alternatively, the airflow from the fresh air inlet can also flow to the air outlet under the guidance of the inner wall of the casing or structures such as air guide plates.

[0071] As the airflow from the fresh air inlet flows towards the air outlet, the humidification device 10 generates humidifying fluid, which is then discharged into the indoor environment through the air outlet under the influence of the airflow, thus achieving the humidification function.

[0072] Please refer to Figure 1 The humidifying device 10 includes a liquid supply component 100, which may be rectangular or approximately rectangular. The length direction of the liquid supply component 100 may be parallel or approximately parallel to the height direction of the humidifying device 10, that is, the length direction of the liquid supply component 100 may be parallel or approximately parallel to the first direction x.

[0073] This can also be understood as the liquid supply component 100 being installed vertically or nearly vertically inside the housing, thereby avoiding the liquid supply component 100 occupying space in the horizontal direction.

[0074] Please combine Figure 1 and Figure 2 The liquid supply unit 100 forms a liquid supply chamber 110 for storing liquid, and the liquid outlet 120 is connected to the bottom of the liquid supply chamber 110 so that the liquid in the liquid supply chamber 110 can flow out from the liquid outlet 120 under the action of gravity. At the same time, the user can also add the liquid required for humidification, such as purified water, distilled water or cooled boiled water, into the liquid supply chamber 110 through the liquid outlet 120.

[0075] In one example, the top of the liquid supply unit 100 is provided with a handle, which the user can hold to operate the liquid supply unit 100 so that the user can add liquid into the liquid supply chamber 110 through the liquid outlet 120.

[0076] like Figure 2 As shown, the humidification device 10 includes a one-way valve 200, which is disposed on the heating assembly 300 and connected to the bottom end of the liquid supply component 100 to mount the liquid supply component 100 onto the heating assembly 300. The one-way valve 200 can be detachably connected to the liquid supply component 100 and the heating assembly 300 to facilitate the removal of the liquid supply component 100 from the heating assembly 300 and to prevent liquid from flowing out of the liquid supply component 100 when it is installed.

[0077] A one-way valve 200 is located at the liquid outlet 120 to connect the liquid outlet 120 to the heating assembly 300. The one-way valve 200 has a closed state; when in the closed state, the one-way valve 200 closes the liquid outlet 120 to prevent liquid in the supply chamber 100 from flowing out through the liquid outlet 120. The one-way valve 200 can also be switched from the closed state to the open state; when in the open state, the one-way valve 200 opens the liquid outlet 120, allowing liquid in the supply chamber 110 to flow out from the liquid outlet 120. Accordingly, the connection direction of the one-way valve 200 is the direction in which liquid flows out of the liquid outlet 120.

[0078] In one embodiment, please refer to Figure 3 The one-way valve 200 includes a seat 210. The seat 210 is tubular and forms a through cavity 211. The extension direction of the seat 210 is parallel or approximately parallel to a first direction x, and the extension direction of the corresponding through cavity 211 is parallel or approximately parallel to the first direction x. The through cavity 211 extends between the top and bottom of the seat 210 in the first direction x.

[0079] The top of the seat 210 is connected to the liquid supply component 100 to connect the top of the through cavity 211 to the liquid outlet 120; the bottom of the seat 210 faces into the liquid storage component 310 to connect the bottom of the through cavity 211 to the humidification cavity 311. Thus, the through cavity 211 connects the liquid outlet 120 and the humidification cavity 311, and the liquid flowing out of the liquid outlet 120 can flow into the humidification cavity 311 after passing through the through cavity 211.

[0080] In some implementations, the inner sidewall of the seat 210 near the top may be provided with a first thread, and the bottom end of the liquid supply component 100 may be provided with a second thread that matches the shape of the first thread. The liquid supply component 100 can be threadedly connected to the seat 210 through the first and second threads to thread the liquid supply component 100 to the one-way valve 200 and to connect the liquid supply chamber 110 to the through chamber 211. In other examples, the seat 210 can also be detachably connected to the liquid supply component 100 through plug-in, snap-fit, or other connection methods.

[0081] The one-way valve 200 also includes a valve core 220, which is disposed in the through cavity 211 and can move relative to the seat 210 along the first direction x to an open position or a closed position. When the valve core 220 is in the open position, the one-way valve 200 is in the open state; when the valve core 220 is in the closed position, the one-way valve 200 is in the closed state.

[0082] For example, the seat 210 has a through cavity located within the through cavity 211 and capable of dividing the through cavity 211 into at least two cavities arranged in a first direction x. The through cavity communicates between the two cavities of the through cavity 211. The valve core 220 may abut against the edge of the through cavity to block the through cavity, thereby blocking the through cavity 211, and the one-way valve 200 is in a closed state; alternatively, the valve core 220 may move away from the through cavity to open the through cavity, thereby opening the through cavity 211, and the one-way valve 200 is in an open state.

[0083] In some implementations, when the valve core 220 moves along the first direction x towards the bottom of the seat 210, the valve core 220 can block the through cavity, so that the one-way valve 200 is in the closed state; when the valve core 220 moves along the first direction x towards the top of the seat 210, the valve core 220 can open the through cavity, so that the one-way valve 200 is in the open state.

[0084] In other implementations, when the valve core 220 moves along the first direction x towards the top of the seat 210, the valve core 220 can block the through cavity, so that the one-way valve 200 is in the closed state; when the valve core 220 moves along the first direction x towards the bottom of the seat 210, the valve core 220 can open the through cavity, so that the one-way valve 200 is in the open state.

[0085] The following embodiments of this application will be described using the example of the one-way valve 200 being in a closed state when the valve core 220 moves along the bottom of the seat 210 in the first direction x.

[0086] Please continue to refer to Figure 3 In one example, the valve core 220 may include a plugging portion 221, a connecting post 222, and an abutment portion 223 arranged and connected sequentially in a first direction x. The connecting post 222 extends along the first direction x and has a first end near the top of the seat 210 and a second end near the bottom of the seat 210. The plugging portion 221 may be disposed at the first end of the connecting post 222, and the abutment portion 223 may be disposed at the second end of the connecting post 222. The connecting post 222 connects the plugging portion 221 and the abutment portion 223.

[0087] The blocking part 221 can move with the valve core 220 and abut against the edge of the through cavity to block the through cavity, so that the one-way valve 200 is in the closed state. Alternatively, the blocking part 221 can also move with the valve core 220 and move away from the through cavity, so that the one-way valve 200 is in the open state.

[0088] In one embodiment, the one-way valve 200 may further include an elastic element 230 located between the valve core 220 and the seat 210. The elastic element 230 can elastically abut against the valve core 220 and position the valve core 220 on the seat 210 by its own elastic force, so that the valve core 220 can block the through-hole, thereby keeping the one-way valve 200 in the closed state.

[0089] For example, the elastic member 230 may extend along the first direction x and be located between the abutment portion 223 and at least a portion of the seat body 210. Along the first direction x, the abutment portion 223, the elastic member 230, and at least a portion of the seat body 210 in contact with the elastic member 230 are arranged sequentially, with the abutment portion 223 located on the side of the elastic member 230 near the bottom of the seat body 210. Thus, the elastic member 230 can drive the abutment portion 223 to move through its elastic force, thereby causing the valve core 220 to move along the first direction x towards the bottom of the seat body 210, thereby causing the sealing portion 221 to abut against the edge of the through-cavity to seal the through-cavity.

[0090] In the above example, the elastic element 230 may include at least one object capable of elastic deformation, such as a spring or a sheet. The material used to make the elastic element 230 may include at least one of the following: metal, rubber, or thermoplastic elastomer. During the movement of the valve core 220, the elastic element 230 may undergo at least one of the following: compression deformation, tensile deformation, bending deformation, or torsional deformation.

[0091] Please refer to Figure 4The humidifying device 10 also includes a heating assembly 300, which includes a liquid storage component 310. The liquid storage component 310 may include a first housing 310a, a second housing 310b, and a bottom housing 310c arranged in a first direction x. The first housing 310a is located at the top of the liquid storage component 310, the bottom housing 310c is located at the bottom of the liquid storage component 310, and the second housing 310b is connected between the first housing 310a and the bottom housing 310c. The first housing 310a and the second housing 310b together form a humidifying chamber 311 for heating the liquid, and the second housing 310b and the bottom housing 310c together form a mounting cavity 312 for accommodating the motor 340. The first housing 310a, the second housing 310b, and the bottom housing 310c can all be connected to each other by at least one of the following connection methods: snap-fit, adhesive, or bolt connection.

[0092] In one embodiment, the humidification chamber 311 includes a liquid storage chamber 3111, a liquid sealing channel 3112, and a heating chamber 3113 connected in sequence. The liquid sealing channel 3112 connects the liquid storage chamber 3111 and the heating chamber 3113. The liquid storage chamber 3111 is located in the first housing 310a and extends along a first direction x, penetrating both ends of the first housing 310a in the first direction x. The top end of the liquid storage chamber 3111 is located at the top of the first housing 310a, and the bottom end of the liquid storage chamber 3111 communicates with the liquid sealing channel 3112.

[0093] A one-way valve 200 is installed inside a liquid storage chamber 3111. A liquid supply component 100 can extend from the top of the liquid storage chamber 3111 into it to be installed on the one-way valve 200. Therefore, during the installation of the liquid supply component 100, the liquid storage chamber 3111 can be used to receive the liquid flowing from the liquid supply component 100 and prevent spillage, thus facilitating user operation and improving the user experience.

[0094] The liquid-sealed channel 3112 is formed by the first housing 310a and the second housing 310b, and connects between the liquid storage chamber 3111 and the heating chamber 3113. For example, the liquid-sealed channel 3112 can communicate with the bottom of the liquid storage chamber 3111 and with the side of the heating chamber 3113 opposite to the liquid storage chamber 3111. When the one-way valve 200 is open, the liquid in the liquid supply element 100 flows into the liquid storage chamber 3111 from the liquid outlet 120, and then flows into the heating chamber 3113 through the liquid-sealed channel 3112.

[0095] The heating chamber 3113 is enclosed by the first housing 310a and the second housing 310b, and is used to heat the liquid. The heating assembly 300 also includes a heating element 320, which is disposed in the liquid storage member 310 and extends into the heating chamber 3113 to heat the liquid in the heating chamber 3113. For example, the heating element 320 may be disposed in the second housing 310b, and the heating element 320 may be located at the bottom of the second housing 310b and the heating chamber 3113. The heating element 320 may include at least one of the following devices that can be used for heating: an electric heating tube or a positive temperature coefficient heater (PT heater).

[0096] The liquid storage device 310 also has an exhaust port 314 communicating with the heating chamber 3113, and the exhaust port 314 is located at the top of the heating chamber 3113. For example, the exhaust port 314 can be provided on the first housing 310a. After the heating element 320 heats the liquid and generates a humidifying fluid, the humidifying fluid can be discharged from the heating chamber 3113 through the exhaust port 314.

[0097] In one embodiment, such as Figure 4 As shown, dashed line a can represent the highest liquid level in heating chamber 3113, and dashed line b can represent the highest liquid level in liquid seal channel 3112. For example, the highest liquid level in heating chamber 3113 can be flush with the highest point of the groove on the side wall of one-way valve seat 210.

[0098] In some implementations, the highest liquid level in the liquid seal channel 3112 is configured to be lower than the highest liquid level in the heating chamber 3113. With this configuration, when the liquid level in the heating chamber 3113 is higher than the highest liquid level in the liquid seal channel 3112, the liquid in the liquid seal channel 3112 can prevent the humidifying fluid in the heating chamber 3113 from leaking from the liquid seal channel 3112 and the opening 313.

[0099] In some implementation methods, please refer to Figure 5 At least a portion of the liquid seal channel 3112 is curved. With this configuration, when the liquid level in the heating chamber 3113 is lower than the highest liquid level in the liquid seal channel 3112, the inner wall of the liquid seal channel 3112 can prevent the humidifying fluid in the heating chamber 3113 from flowing along the liquid seal channel 3112, thus preventing leakage of the humidifying fluid from the liquid seal channel 3112 and the opening 313. Furthermore, when the liquid supply component 100 supplies liquid to the liquid storage component 310, the flow rate of the liquid in the liquid delivery channel can be reduced, preventing a large amount of low-temperature liquid from the liquid supply component 100 from rapidly flowing into the high-temperature heating chamber 3113 and causing boiling over. This avoids damage to the liquid storage component 310, extends the service life of the humidification device 10, and improves the safety and reliability of the air conditioning indoor unit.

[0100] In some implementations, the highest liquid level in the heating chamber 3113 is configured to be lower than the bottom of the liquid supply component 100. With this configuration, the temperature of the liquid in the humidification chamber 311 is not easily conducted to the liquid supply component 100, which can prevent the liquid supply component 100 from heating up and prevent the user from being scalded when operating the liquid supply component 100.

[0101] Please refer to the above again. Figure 2 The second housing 310b, together with the bottom housing 310c, forms a mounting cavity 312. The mounting cavity 312 is spaced apart from the humidification cavity 311, and the mounting cavity 312 and the humidification cavity 311 can be arranged in the height direction of the humidification device 10, that is, in the first direction x. The humidification cavity 311 is located above the mounting cavity 312 and closer to the top of the humidification device 10. For example, the liquid storage cavity 3111 can be located above the mounting cavity 312.

[0102] The above settings can prevent liquid in the humidification chamber 311 from flowing into the installation chamber 312, reduce the risk of damage to the motor 340 when exposed to water, and extend the service life of the humidification device 10.

[0103] Please combine Figure 2 and Figure 6 The drive unit 330 includes a motor 340, a drive component 350, and a transmission component 360. Both the motor 340 and the drive component 350 are located within the mounting cavity 312. The motor 340 can be mounted in at least one of the bottom housing 310c or the second housing 310b. The drive component 350 is mounted on the output shaft of the motor 340 and configured to rotate under the drive of the motor 340. The transmission component 360 is mounted on the liquid reservoir 310 and rotatably connected to the liquid reservoir 310.

[0104] The transmission member 360 has a first end and a second end, which are spaced apart in the extending direction of the transmission member 360. The rotation axis of the transmission member 360 is located between the first end and the second end. The first end of the transmission member 360 is located in the mounting cavity 312 and is connected to the drive member 350. The second end of the transmission member 360 extends into the humidification cavity 311 and contacts the one-way valve 200.

[0105] When the motor 340 drives the drive component 350 to rotate, the drive component 350 can drive the first end of the transmission component 360 to rotate around the rotation axis of the transmission component 360, so that the second end of the transmission component 360 can move to the trigger position or the disengagement position respectively.

[0106] Please combine Figure 7 and Figure 8When the transmission component 360 is in the trigger position, the second end of the transmission component 360 contacts the one-way valve 200. For example, the second end of the transmission component 360 can abut against the valve core 220 of the one-way valve 200 and push the valve core 220 to the open position so that the one-way valve 200 is in the open state and the liquid supply component 100 supplies liquid to the humidification chamber 311.

[0107] Please combine Figure 9 and Figure 10 When the transmission component 360 is in the disengaged position, the second end of the transmission component 360 can disengage from the one-way valve 200 and the valve core 220, so that the one-way valve 200 is in the closed state and the liquid supply component 100 stops supplying liquid to the humidification chamber 311.

[0108] Through the above configuration, the drive unit 330 can control the one-way valve 200 to switch between open and closed states, thereby precisely controlling the liquid supply component 100 to supply liquid into the liquid storage component 310 and controlling the liquid level in the liquid storage component 310. This prevents excessive liquid in the liquid storage component 310 from causing a slow heating rate, thus improving humidification efficiency. Furthermore, it indirectly increases the gas content in the humidification chamber 311, thereby preventing the liquid from boiling over when the humidification chamber 311 heats the liquid.

[0109] Meanwhile, the drive unit 330 abuts against the one-way valve 200 through the transmission component 360 to control the one-way valve 200 to switch between the open and closed states. The one-way valve 200 and the liquid supply component 100 do not directly contact the motor 340 or connect to the circuit, thus avoiding the one-way valve 200 and the liquid supply component 100 from being electrified. There is no risk of electric shock when the user adds water to the humidifier 10, which facilitates user operation, improves the safety of the indoor unit of the air conditioner, and enhances the user experience.

[0110] Furthermore, the drive unit 330 has a simple and reliable structure and low control cost.

[0111] In one embodiment, please refer to Figure 9 , Figure 10 and Figure 11 In the height direction of the humidifying device 10, the heights of both the first end and the second end of the transmission member 360 are lower than the height of the rotation axis. The top of the humidifying chamber 311 has an opening 313; for example, the opening 313 can be located at the top of the first housing 310a. Correspondingly, the opening 313 and the mounting cavity 312 are arranged in the height direction of the humidifying device 10, with the mounting cavity 312 closer to the bottom of the humidifying device 10 than the opening 313, meaning the height of the opening 313 is higher than the height of the mounting cavity 312. The second end of the transmission member 360 can extend into the humidifying chamber 311 through the opening 313 and contact the one-way valve 200.

[0112] With the above settings, the liquid in the humidification chamber 311 is less likely to flow out from the opening 313, thereby preventing the liquid from flowing into the installation chamber 312, reducing the risk of the motor 340 being damaged by water, and extending the service life of the humidification device 10.

[0113] In the example above, the height of the rotation axis of the transmission component 360 can be higher than the height of the opening 313.

[0114] In one embodiment, please combine Figure 6 and Figure 8 The transmission component 360 includes a first connecting rod 361, a rotating part 363, and a second connecting rod 362 connected in sequence. The rotating part 363 is connected between the first connecting rod 361 and the second connecting rod 362 and is rotatably connected to the liquid storage component 310. Accordingly, the rotation axis of the transmission component 360 is located on the rotating part 363, and both the first connecting rod 361 and the second connecting rod 362 can rotate around the rotating part 363. The first end of the transmission component 360 is located on the first connecting rod 361, which is used for transmission connection with the drive component 350. The second end of the transmission component 360 is located on the second connecting rod 362, which is used for contact with the one-way valve 200.

[0115] The first connecting rod 361 has a first end and a second end. The first end of the first connecting rod 361 can be connected to the rotating part 363, and the second end of the first connecting rod 361 is used for transmission connection with the driving member 350 and is configured to rotate about the rotation axis under the drive of the driving member 350. The first end and the second end of the first connecting rod 361 are arranged in the height direction of the humidifying device 10, and the second end of the first connecting rod 361 is closer to the bottom of the humidifying device 10 than the first end of the first connecting rod 361, that is, the height of the first end of the first connecting rod 361 is higher than the height of the second end of the first connecting rod 361.

[0116] The second connecting rod 362 has a first end and a second end. The first end of the second connecting rod 362 can be connected to the rotating part 363, and the second end of the second connecting rod 362 is used to contact the one-way valve 200 and is configured to abut against or disengage from the one-way valve 200 when the second connecting rod 362 rotates about the rotation axis. The first end and the second end of the second connecting rod 362 are arranged in the height direction of the humidifying device 10, and the second end of the second connecting rod 362 is closer to the bottom of the humidifying device 10 than the first end of the second connecting rod 362; that is, the height of the first end of the second connecting rod 362 is higher than the height of the second end of the second connecting rod 362.

[0117] With the above configuration, the first connecting rod 361, the rotating part 363, and the second connecting rod 362 are sequentially connected and together constitute the transmission component 360, making the transmission component 360 approximately "U"-shaped. The transmission component 360 can be driven and connected to the motor 340 within the mounting cavity 312, and extends from the mounting cavity 312 towards the top of the humidification device 10 to be rotatably connected to the top of the liquid storage component 310. Then, it extends into the humidification cavity 311 through the opening 313, and further extends to the one-way valve 200. Thus, the transmission component 360 connects the motor 340 and the one-way valve 200, enabling the motor 340 to control the one-way valve 200 to switch between the open and closed states via the transmission component 360.

[0118] In some implementations, the liquid storage component 310 is provided with a rotating frame 316. For example, the rotating frame 316 can be located on the top of the liquid storage component 310, and the rotating frame 316 is provided with a through hole. The rotating part 363 is provided with a rotating protrusion 3631, which can pass through the through hole and be rotatably disposed in the through hole, so that the rotating part 363 can rotate on the rotating frame 316, thereby rotatably disposing the transmission component 360 on the liquid storage component 310.

[0119] In some other implementations, the transmission component 360 can be rotatably mounted on the liquid storage component 310 via a structure such as a shaft or hinge.

[0120] In one example, such as Figure 7 and Figure 8 As shown, a clearance groove 315 may be provided on the outer wall of the liquid storage component 310. The extension direction of the clearance groove 315 is parallel or approximately parallel to the first direction x. The top end of the clearance groove 315 is located at the top of the liquid storage component 310, and the bottom end of the clearance groove 315 communicates with the mounting cavity 312. At least a portion of the first connecting rod 361 can be disposed within the clearance groove 315 and swing within the clearance groove 315. Through the above arrangement, the clearance groove 315 can provide swing space for the first connecting rod 361 and protect the first connecting rod 361.

[0121] In one example, such as Figures 9 to 11 As shown, the liquid storage component 310 has a clearance channel 3114 communicating with the opening 313, and the clearance channel 3114 includes at least a portion of the humidification chamber 311. For example, the clearance channel 3114 may be located between at least a portion of the first housing 310a that surrounds the liquid storage chamber 3111 and at least a portion of the second housing 310b that constitutes the outer wall of the liquid storage component 310. The extension direction of the clearance channel 3114 is parallel or approximately parallel to the first direction x, the top end of the clearance channel 3114 communicates with the opening 313, and the bottom end of the clearance channel 3114 may communicate with the bottom of the liquid storage chamber 3111. With the above arrangement, the clearance channel 3114 can provide swing space for the second connecting rod 362 and allow the second connecting rod 362 to extend toward the one-way valve 200.

[0122] In one embodiment, the first connecting rod 361 includes a first extension 3611 and a second extension 3612. The first extension 3611 is connected to the rotating part 363, and at least a portion of the first extension 3611 can be located within the clearance groove 315. The second extension 3612 is connected to the end of the first extension 3611 facing away from the rotating part 363 and is inclined relative to the first extension 3611, i.e., there is an angle between the second extension 3612 and the first extension 3611. The second extension 3612 is located within the mounting cavity 312 and extends towards the driving member 350 so as to be able to drively connect with the driving member 350, thereby drivingly connecting the transmission member 360 and the motor 340. Correspondingly, the first end of the first connecting rod 361 is located in the second extension 3612.

[0123] With the above configuration, the first connecting rod 361 can be connected to the motor 340 and the drive component 350 via the second extension section 3612.

[0124] In one embodiment, the second connecting rod 362 includes a third extension 3621 and a bent section 3622. The third extension 3621 is connected to the rotating portion 363, and at least a portion of the third extension 3621 is located within the clearance channel 3114. The bent section 3622 is disposed at the end of the third extension 3621 opposite to the rotating portion 363 and is bent relative to the third extension 3621. The bent section 3622 extends towards the bottom of the check valve 200 to be able to contact the valve core 220 of the check valve 200 and to avoid the check valve 200 and the first housing 310a when the transmission member 360 rotates. Correspondingly, the second end of the first connecting rod 361 is located in the bent section 3622.

[0125] With the above configuration, the second connecting rod 362 can contact the valve core 220 of the check valve 200 through the bent section 3622, thereby controlling the check valve 200 to switch between the open and closed states.

[0126] In one embodiment, the second end of the second connecting rod 362 has an abutment 3623, which may be located at the end of the bent section 3622 that contacts the check valve 200. The abutment 3623 is used to contact the bottom of the check valve 200, for example, the top may contact the abutment portion 223 of the valve core 220, and is used to abut the check valve 200 when the second connecting rod 362 rotates, so that the check valve 200 is in the open state.

[0127] With the above configuration, the transmission component 360 can abut against the valve core 220 through the top abutment 3623, causing the valve core 220 to move along the first direction x towards the top of the seat 210, thereby changing the one-way valve 200 from the closed state to the open state.

[0128] In one embodiment, the drive member 350 has two drive arms 351 on its circumferential side, and the two drive arms 351 are spaced apart circumferentially from the output shaft of the motor 340. The second end of the first connecting rod 361 is located between the two drive arms 351, that is, the first end of the transmission member 360 is located between the two drive arms 351. Exemplarily, the second extension 3612 of the first connecting rod 361 may be located between the two drive arms 351. In the first direction x, one of the two drive arms 351 is located on the side of the second end of the first connecting rod 361 near the top of the humidifier 10, which can also be understood as being located above the second end of the first connecting rod 361; the other is located on the side of the second end of the first connecting rod 361 near the bottom of the humidifier 10, which can also be understood as being located below the second end of the first connecting rod 361.

[0129] During the rotation of the drive member 350 under the drive of the motor 340, one of the two drive arms 351 can abut against the first connecting rod 361, causing the first connecting rod 361 to rotate. Furthermore, when different drive arms 351 abut against the first connecting rod 361, the first connecting rod 361 rotates in different directions. Thus, the rotating member can oscillate back and forth under the drive of the motor 340, causing the transmission member 360 to rotate in different directions.

[0130] For example, such as Figure 8 As shown, when the drive member 350 rotates clockwise, the lower drive arm 351 can abut against the first connecting rod 361, causing the first connecting rod 361 to rotate counterclockwise around the rotation axis of the transmission member 360. Correspondingly, the second connecting rod 362 rotates counterclockwise around the rotation axis of the transmission member 360, and the transmission member 360 abuts against the valve core 220, causing the one-way valve 200 to switch to the open state.

[0131] like Figure 9 As shown, when the drive member 350 rotates counterclockwise, the upper drive arm 351 can abut against the first connecting rod 361, causing the first connecting rod 361 to rotate clockwise around the rotation axis of the transmission member 360. Correspondingly, the second connecting rod 362 rotates clockwise around the rotation axis of the transmission member 360, allowing the transmission member 360 to disengage from the valve core 220, and the one-way valve 200 to switch to the closed state.

[0132] With the above settings, the motor 340 can drive the transmission component 360 to rotate in different directions via the drive component 350, so as to control the one-way valve 200 to switch between the open and closed states.

[0133] It is understandable that in the above examples, the rotation directions such as "clockwise" and "counterclockwise" only correspond to the viewpoint shown in the attached figure. When the viewpoint changes, the rotation direction also changes accordingly.
