Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly 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 out of 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 includes a seat and a valve core. The seat is disposed on the liquid supply component and has a through cavity communicating with the liquid outlet. The valve core is disposed in the through cavity and can move relative to the seat to switch the one-way valve between an open state and a closed state. When the one-way valve is in the closed state, it closes the liquid outlet. To prevent liquid from flowing out of the liquid supply component through the liquid outlet, the heating assembly includes a liquid storage component and a drive unit. The liquid storage component has a humidification chamber and an installation chamber inside. The humidification chamber is connected to the through chamber and is used to receive the liquid flowing out of the liquid outlet and heat the liquid to generate humidifying fluid. The installation chamber and the humidification chamber are isolated from each other. The drive unit includes an electromagnetic drive device and a drive element that can be magnetically driven. The drive element is located in the valve core, and the electromagnetic drive device is located in the installation chamber. The electromagnetic drive device is configured to generate magnetic force to drive the drive element to move, so that the drive element drives the valve core to move to the open position. When the valve core is in the open position, the one-way valve is in the open state, and the liquid supply component supplies liquid to the humidification chamber.

[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 drive unit, driven by the electromagnetic drive device, causes the one-way valve to switch between open and closed states. The one-way valve and the liquid supply component do not directly contact the electromagnetic drive device and are not connected to the circuit, thus avoiding the one-way valve and the liquid supply component from becoming energized. 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 isolation between the installation chamber and the humidification chamber prevents liquid from the humidification chamber from entering the installation chamber, thereby preventing damage to the electromagnetic drive device in the installation chamber from water, reducing the risk of water and electricity leakage, and improving the safety and protection of the indoor unit of the air conditioner.

[0012] Optionally, the liquid storage device includes an isolation wall that divides the interior of the liquid storage device into a humidification chamber and an installation chamber. The drive unit is located on the side of the valve core near the isolation wall, and the electromagnetic drive device is located on the isolation wall and is arranged opposite to the drive unit.

[0013] With the above settings, the drive unit can control the one-way valve to switch between open and closed states with relatively precise and rapid control through the electromagnetic drive device and drive components. This allows for more precise control of the liquid supply component to supply liquid into the liquid storage component and control of the liquid level in the liquid storage component, avoiding problems such as low humidification efficiency or boiling over due to excessive liquid in the liquid storage component.

[0014] Furthermore, the electromagnetic drive device does not directly contact the drive components or the check valve. The mounting cavity where the electromagnetic drive device is located and the humidification cavity where the check valve is located are isolated by an isolation wall, which increases the sealing effect between the mounting cavity and the humidification cavity, avoids water leakage in the mounting cavity, reduces the risk of the motor being damaged by water, and extends the service life of the humidification device.

[0015] Meanwhile, the one-way valve is not connected to the circuit, which can prevent the one-way valve and liquid supply components from becoming electrified. Users are not at risk of electric shock when adding water to the humidifier, which makes it easier for users to operate and improves the safety of the indoor unit of the air conditioner, thus enhancing the user experience.

[0016] Optionally, the isolation wall is a straight wall extending in the horizontal direction, and the electromagnetic drive device is attached to the side of the isolation wall opposite to the one-way valve.

[0017] With the above setup, the electromagnetic drive device and the drive component move closer to each other, the drive component can respond quickly to the electromagnetic drive device, and the electromagnetic drive device can control the movement of the drive component more accurately and quickly, so as to control the one-way valve to switch between the open and closed states more accurately and quickly.

[0018] Optionally, the check valve also includes an elastic element located between the valve core and the seat. The elastic element is configured to keep the check valve in a closed state by its own elastic force. The drive element can drive the valve core to move away from or towards the isolation wall to open the through chamber and keep the check valve in an open state.

[0019] With the above configuration, the valve core can open the through cavity under the action of the driving component to supply liquid to the accumulator, and can close the through cavity under the action of the elastic component to prevent the supply component from supplying liquid to the accumulator.

[0020] Optionally, the valve core includes a plugging part, a connecting column, and an abutting part. When the one-way valve is in the closed state, the plugging part blocks the through cavity, the connecting column is connected to the plugging part, and the connecting column has a first end and a second end spaced apart in its own extending direction. The second end of the connecting column is closer to the isolation wall than the first end of the connecting column. The driving member is located at the second end of the connecting column, the abutting part is located on the connecting column, and the elastic member is located between the abutting part and at least part of the seat.

[0021] With the above configuration, the driving component can drive the sealing part to open or close the through cavity.

[0022] Optionally, the driving element is a ferromagnetic material that can be attracted by an electromagnetic driving device, which is configured to generate a magnetic force to attract the driving element and drive it to move.

[0023] With the above settings, the drive unit can respond quickly to the electromagnetic drive device, and the electromagnetic drive device can control the movement of the drive unit more accurately and quickly, so as to control the one-way valve to switch between the open and closed states more accurately and quickly.

[0024] Optionally, the driving element is a magnetic element, and the electromagnetic driving device is configured to drive the driving element to move by attracting or repelling it with its own magnetic force.

[0025] With the above settings, the drive unit can respond quickly to the electromagnetic drive device, and the electromagnetic drive device can control the movement of the drive unit more accurately and quickly, so as to control the one-way valve to switch between the open and closed states more accurately and quickly.

[0026] Optionally, the humidification chamber includes an injection tank and a heating chamber that are interconnected. The injection tank and the mounting chamber are arranged in the height direction of the humidification device. The injection tank is located at the top of the mounting chamber. The heating chamber is used to heat the liquid. The injection tank has a first slot and a second slot arranged in the height direction of the humidification device. The first slot is located at the top of the injection tank, and the second slot is located at the bottom of the injection tank and communicates with the heating chamber. A one-way valve is located in the injection tank, and a liquid supply component extends into the injection tank from the first slot and is connected to the one-way valve.

[0027] With the above settings, during the installation of the liquid supply component, the liquid injection tank can be used to catch the liquid flowing out of the liquid supply component and prevent the liquid from spilling out, which facilitates user operation and improves the user experience.

[0028] Optionally, the indoor unit of the air conditioner also includes a liquid level sensor and a controller. The liquid level sensor is located inside the humidification chamber and is configured to detect the liquid level inside the humidification chamber. Both the electromagnetic drive device and the liquid level sensor are electrically connected to the controller. The controller is configured to control the electromagnetic drive device to drive the drive component to move to the open position when the liquid level sensor detects that the liquid level inside the humidification chamber is lower than the liquid level sensor, so that the liquid supply component supplies liquid to the humidification chamber.

[0029] The above settings allow for precise control of the liquid supply from the liquid supply unit to the liquid storage unit, and control of the liquid level in the humidification chamber. This prevents excessive liquid in the storage unit from causing slow heating and improves humidification efficiency. Furthermore, it indirectly increases the gas content in the humidification chamber, thus preventing the liquid from boiling over during heating. Simultaneously, by ensuring the maximum liquid level in the humidification chamber is lower than that of the liquid supply unit, the temperature of the liquid in the humidification chamber is less likely to be conducted to the liquid supply unit, preventing overheating and burns to the user when operating the liquid supply unit.

[0030] 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.

[0031] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Please refer to Figures 1 to 3 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.

[0057] 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.

[0058] 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.

[0059] The one-way valve 200 includes a seat 210 and a valve core 220. The seat 210 is disposed on the liquid supply component 100 and has a through cavity 211 communicating with the liquid outlet 120. The valve core 220 is disposed in the through cavity 211 and can move relative to the seat 210 to switch the one-way valve 200 between an open state and a closed state. When the one-way valve 200 is in the closed state, it closes the liquid outlet 120 to prevent liquid in the liquid supply component 100 from flowing out through the liquid outlet 120. When the one-way valve 200 is in the open state, it opens the liquid outlet 120, allowing liquid in the liquid supply component 100 to flow out through the liquid outlet 120.

[0060] 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 that are isolated from each other. The mounting chamber 312 is used to house the drive unit 330. The humidification chamber 311 is used to receive liquid flowing out of the outlet 120 when the one-way valve 200 is open. The humidification chamber 311 is also used to heat the liquid to generate a humidifying fluid.

[0061] The drive unit 330 includes an electromagnetic drive device 331 and a magnetically driven drive member 332. The drive member 332 is disposed in the valve core 220, and the electromagnetic drive device 331 is disposed in the mounting cavity 312. The electromagnetic drive device 331 is configured to generate a magnetic force to drive the drive member 332 to move, so that the drive member 332 drives the valve core 220 to the open position. When the valve core 220 is in the open position, the one-way valve 200 is in the open state, and the liquid supply member 100 supplies liquid to the humidification chamber 311.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] Furthermore, the drive unit 332, driven by the electromagnetic drive device 331, drives the one-way valve 200 to switch between the open and closed states. The one-way valve 200 and the liquid supply device 100 do not directly contact the electromagnetic drive device 331 and are not connected to the circuit, thus avoiding the one-way valve 200 and the liquid supply device 100 from being energized. There is no risk of electric shock when the user adds water to the humidifier 10, which is convenient for the user to operate and improves the safety of the indoor unit of the air conditioner, thereby enhancing the user experience.

[0066] Meanwhile, the isolation between the installation cavity 312 and the humidification cavity 311 prevents liquid in the humidification cavity 311 from entering the installation cavity 312, thereby preventing the electromagnetic drive device 331 in the installation cavity 312 from being damaged by water, reducing the risk of water leakage and electric leakage, and improving the safety and protection effect of the air conditioner indoor unit.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] Please combine Figure 2 and Figure 3 The humidifying 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 during installation.

[0076] 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.

[0077] In one embodiment, 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.

[0078] The top of the seat 210 is connected to the liquid supply component 100 to connect the liquid outlet 120 to the through cavity 211, allowing the liquid flowing out of the outlet 120 to pass through the through cavity 211 and then flow out from the bottom of the seat 210. In some implementations, such as Figure 4 and Figure 5 As shown, the inner sidewall of the seat 210 near the top may be provided with a first thread 213, and the bottom end of the liquid supply component 100 may be provided with a second thread 130 that matches the shape of the first thread 213. The liquid supply component 100 can be threadedly connected to the seat 210 through the first thread 213 and the second thread 130 to connect the liquid supply chamber 110 and 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.

[0079] Please refer to the above again. Figure 3 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 the open position or the 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.

[0080] In some implementations, the valve core 220 includes a plugging portion 221, a connecting post 222, and an abutting portion 223 arranged and connected to each other 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. Both the plugging portion 221 and the abutting portion 223 are provided on the connecting post 222, and in the extending direction of the connecting post 222, the plugging portion 221 may be spaced apart from the second end of the connecting post 222.

[0081] The sealing part 221 is used to seal or open the through cavity 211, so that the one-way valve 200 switches between a closed state and an open state. For example, please refer to... Figure 6 and Figure 7 The seat 210 has a through cavity 212, which is located within the through cavity 211 and can divide the through cavity 211 into at least two cavities arranged in the first direction x. The through cavity 212 connects the two cavities of the through cavity 211. Figure 3 As shown, the blocking part 221 can abut against the edge of the through cavity 212 to block the through cavity 212, thereby blocking the through cavity 211. Or, as Figure 7 As shown, the blocking part 221 can be moved away from the through cavity 212 and open the through cavity 212, thereby opening the through cavity 211.

[0082] In some implementations, the one-way valve 200 may also include an elastic element 230, which is 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 through its own elastic force, so that the valve core 220 can block the through port 212, thereby keeping the one-way valve 200 in the closed state.

[0083] For example, the elastic element 230 may extend along the first direction x and be located between the abutment portion 223 and at least part of the seat 210. The elastic element 230 may drive the abutment portion 223 to move by elastic force, thereby causing the valve core 220 to move relative to the seat 210 along the first direction x, so that the blocking portion 221 abuts against the edge of the through cavity 212, blocking the through cavity 212.

[0084] 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.

[0085] In one embodiment, such as Figure 7 As shown, the valve core 220 can be configured to move to the top of the seat 210 in the first direction x to the open position, and to move to the bottom of the seat 210 in the first direction x to the closed position.

[0086] Correspondingly, the sealing part 221 can be located at the first end of the connecting post 222 near the top of the seat 210, the abutting part 223 can be located at the second end of the connecting post 222 near the bottom of the seat 210, and the elastic member 230 can be located on the side of the abutting part 223 near the top of the seat 210.

[0087] In another embodiment, please combine Figure 8 and Figure 9 The valve core 220 can be configured to move to a closed position along the top of the seat 210 in the first direction x, and to move to an open position along the bottom of the seat 210 in the first direction x.

[0088] Correspondingly, the sealing part 221 can be located between the first end and the second end of the connecting post 222, the abutting part 223 can be located at the first end of the connecting post 222 near the top of the seat 210, and the elastic member 230 can be located on the side of the abutting part 223 near the bottom of the seat 210.

[0089] Please refer to the above again. Figure 3 The 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, 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. 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 electromagnetic drive device 331. The highest liquid level in the humidification chamber 311 can be flush with the bottom of the one-way valve 200 seat 210, or the highest liquid level in the humidification chamber 311 can be flush with the highest point of the opening on the side wall of the one-way valve 200 seat 210.

[0090] In one embodiment, such as Figure 10 As shown, the humidification chamber 311 includes an inter-connected liquid injection tank 3111, a liquid delivery channel 3112, and a heating chamber 3113 for heating the liquid. The liquid injection tank 3111 is located in the first housing 310a. A first opening and a second opening of the liquid injection tank 3111 are arranged in a first direction x. The first opening is located at the top of the liquid injection tank 3111, and the second opening is located at the bottom of the liquid injection tank 3111 and communicates with the heating chamber 3113 through the liquid delivery channel 3112.

[0091] A one-way valve 200 is installed in the injection tank 3111. The liquid supply component 100 can extend into the injection tank 3111 from the first slot to be installed on the one-way valve 200. Thus, during the user's installation of the liquid supply component 100, the injection tank 3111 can be used to catch the liquid flowing out of the liquid supply component 100 and prevent liquid from spilling, which facilitates user operation and improves the user experience.

[0092] The liquid delivery channel 3112 is formed by the first housing 310a and the second housing 310b, and connects the liquid injection tank 3111 and the heating chamber 3113. For example, the liquid delivery channel 3112 can connect to the second opening at the bottom of the liquid injection tank 3111 and to the side of the heating chamber 3113 opposite to the liquid injection tank 3111. When the one-way valve 200 is open, the liquid in the liquid supply component 100 flows into the liquid injection tank 3111 from the liquid outlet 120, and then flows into the heating chamber 3113 through the liquid delivery channel 3112.

[0093] 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 heating devices: an electric heating tube or a positive temperature coefficient heater (PTC heater).

[0094] The liquid storage device 310 also has an exhaust port 313 communicating with the heating chamber 3113, and the exhaust port 313 is located at the top of the heating chamber 3113. For example, the exhaust port 313 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 313.

[0095] In one embodiment, at least a portion of the liquid delivery channel 3112 is curved. This reduces the flow rate of the liquid in the liquid delivery channel 3112, preventing a large amount of low-temperature liquid from the liquid supply unit 100 from rapidly flowing into the high-temperature heating chamber 3113 and causing boiling over, thus avoiding damage to the liquid storage unit 310, extending the service life of the humidification device 10, and improving the safety and reliability of the air conditioning indoor unit.

[0096] In one embodiment, the indoor unit of the air conditioner may further include a liquid level sensor. The liquid level sensor may be disposed within the humidification chamber 311 and used to detect the liquid level within the humidification chamber 311. For example, the liquid level sensor may be disposed within the heating chamber 3113, and the liquid level sensor may include at least one of the following sensors: a hydrostatic liquid level sensor, an ultrasonic liquid level sensor, or a laser liquid level sensor.

[0097] The indoor unit of the air conditioner also includes a controller, which can be electrically connected to the electromagnetic drive device 331 and the liquid level sensor. The liquid level sensor can send an electrical signal to the controller when the liquid level in the heating chamber 3113 is lower than the minimum liquid level. The controller can then control the electromagnetic drive device 331 based on the electrical signal from the liquid level sensor, thereby controlling the liquid supply unit 100 to supply liquid to the liquid storage unit 310. For example, in an example where the liquid level sensor includes a laser sensor, when the liquid level in the humidification chamber 311 is lower than the liquid level sensor, the liquid level sensor can transmit an electrical signal to the controller. The controller can then control the electromagnetic drive device 331 to drive the drive element 332 and the valve core 220 to the open position, causing the liquid supply unit 100 to supply liquid to the humidification chamber 311 of the liquid storage unit 310. When the liquid level in the humidification chamber 311 reaches the liquid level sensor, the liquid level sensor transmits an electrical signal to the controller again. The controller can control the electromagnetic drive device 331 to drive the drive component 332 and the valve core 220 to move to the closed position, and the liquid supply component 100 stops supplying liquid to the humidification chamber 311 of the liquid storage component 310.

[0098] Through the above settings, the liquid supply from the liquid supply unit 100 to the liquid storage unit 310 can be precisely controlled, and the liquid level in the humidification chamber 311 can be controlled to avoid excessive liquid in the liquid storage unit 310, which would lead to a slower heating rate and improve humidification efficiency. Furthermore, it indirectly increases the gas content in the humidification chamber 311, thereby preventing the liquid from boiling over when heating. Simultaneously, by ensuring that the maximum liquid level in the humidification chamber 311 is lower than that of the liquid supply unit 100, the temperature of the liquid in the humidification chamber 311 is less likely to be conducted to the liquid supply unit 100, preventing the liquid supply unit 100 from overheating and avoiding burns to the user when operating it.

[0099] In the above example, the controller may include at least one of a central processing unit (CPU), a system on chip (SOC), or an application-specific integrated circuit (ASIC).

[0100] Please combine Figures 1 to 3 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. For example, the mounting cavity 312 can be arranged with the liquid injection tank 3111 in the first direction x, and the liquid injection tank 3111 can be located at the top of the mounting cavity 312. The mounting cavity 312 can also be spaced apart from the heating cavity 3113 in a direction perpendicular or approximately perpendicular to the first direction x.

[0101] In one embodiment, the liquid storage device 310 includes a partition wall 314 that divides the interior of the liquid storage device 310 into a humidification chamber 311 and a mounting chamber 312. Exemplarily, the partition wall 314 may be located between the liquid injection tank 3111 and the mounting chamber 312, with the partition wall 314 located at the bottom of the liquid injection tank 3111 and at the top of the mounting chamber 312. The partition wall 314 has an angle with a first direction x; for example, the partition wall 314 may be perpendicular or approximately perpendicular to the first direction x, or it can be understood that the partition wall 314 is a straight wall extending in a horizontal direction.

[0102] The drive unit 330 includes an electromagnetic drive device 331 and a magnetically driven drive element 332. The electromagnetic drive device 331 and the drive element 332 can be arranged in the first direction x and are located on opposite sides of the isolation wall 314. The electromagnetic drive device 331 is disposed within the mounting cavity 312 and is used to generate magnetic force to move the drive element 332. The drive element 332 is disposed on the valve core 220 and can drive the valve core 220 to move.

[0103] With the above settings, the drive unit 330 can control the one-way valve 200 to switch between the open and closed states more accurately and quickly through the electromagnetic drive device 331 and the drive component 332, so as to control the liquid supply component 100 to supply liquid into the liquid storage component 310 more accurately, and control the liquid level in the liquid storage component 310, so as to avoid problems such as low humidification efficiency or boiling over due to excessive liquid in the liquid storage component 310.

[0104] Furthermore, the electromagnetic drive device 331 does not directly contact the drive component 332 and the one-way valve 200. The mounting cavity 312 where the electromagnetic drive device 331 is located and the humidification cavity 311 where the one-way valve 200 is located are isolated by the isolation wall 314, which increases the sealing effect between the mounting cavity 312 and the humidification cavity 311, can prevent water leakage from the mounting cavity 312, reduce the risk of the motor being damaged by water, and extend the service life of the humidification device 10.

[0105] Meanwhile, the one-way valve 200 is not connected to the circuit, which can prevent the one-way valve 200 and the liquid supply component 100 from being electrified. When the user adds water to the humidifier 10, there is no risk of electric shock. This makes it easier for the user to operate and improves the safety of the indoor unit of the air conditioner, thus enhancing the user experience.

[0106] In some implementations, the electromagnetic drive 331 can be an electromagnet, which can be configured to carry an electric current to generate a magnetic force that moves the drive 332.

[0107] In some other implementations, the electromagnetic drive 331 can be a magnet, which can be configured to move along a first direction x to approach or move away from the isolation wall 314, and the drive 332 can be moved as the magnet approaches the isolation wall 314.

[0108] For example, the electromagnetic drive device 331 may further include a linear guide rail, and a magnet may be disposed on a slider in the linear guide rail. The linear guide rail may be arranged along a first direction x, and the slider may slide on the guide rail to drive the magnet closer to or away from the isolation wall 314. Alternatively, the electromagnetic drive device 331 may further include an electric cylinder, and a magnet may be disposed on the output shaft of the electric cylinder. The output shaft of the electric cylinder may be arranged along a first direction x to drive the magnet closer to or away from the isolation wall 314.

[0109] In the above example, the electromagnetic drive device 331 can generate a magnetic force to attract the drive member 332, causing the drive member 332 to move closer to the electromagnetic drive device 331 and the isolation wall 314. Correspondingly, the valve core 220 moves along the first direction x towards the bottom of the seat 210, causing the one-way valve 200 to switch between an open and closed state. Alternatively, the electromagnetic drive device 331 can also generate a magnetic force to repel the drive member 332, causing the drive member 332 to move away from the electromagnetic drive device 331 and the isolation wall 314. Correspondingly, the valve core 220 moves along the first direction x towards the top of the seat 210, causing the one-way valve 200 to switch between an open and closed state.

[0110] In some implementations, the drive element 332 is a ferromagnetic material. Thus, the drive element 332 can be attracted by the electromagnetic drive device 331 and moved towards the electromagnetic drive device 331 and the isolation wall 314.

[0111] In some implementations, the driving element 332 is a magnetic element. When the magnetic poles of the driving element 332 are opposite to those of the electromagnetic driving device 331, the driving element 332 can be attracted by the electromagnetic driving device 331 and move towards the electromagnetic driving device 331 and the isolation wall 314. When the magnetic poles of the driving element 332 are the same as those of the electromagnetic driving device 331, the driving element 332 can be repelled by the electromagnetic driving device 331 and move away from the electromagnetic driving device 331 and the isolation wall 314.

[0112] In one embodiment, the drive element 332 is located on the side of the valve core 220 near the isolation wall 314. For example, the drive element 332 may be located at the end of the valve core 220 near the bottom of the seat 210. The electromagnetic drive device 331 is located on the isolation wall 314 and is correspondingly arranged with the drive element 332. In an example where the isolation wall 314 is a straight wall, the electromagnetic drive device 331 may be attached to the side of the isolation wall 314 opposite to the one-way valve 200.

[0113] With the above configuration, the electromagnetic drive device 331 and the drive component 332 move closer to each other, the drive component 332 can respond quickly to the electromagnetic drive device 331, and the electromagnetic drive device 331 can control the movement of the drive component 332 more accurately and quickly, so as to control the one-way valve 200 to switch between the open state and the closed state more accurately and quickly.
