Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air treatment, in particular to an air treatment device of an air conditioner and the air conditioner. BACKGROUND

[0002] In the related art, an air conditioner with air treatment function usually uses a high-efficiency HEPA filter screen for filtering. On the one hand, the HEPA filter screen needs to be replaced regularly due to the limitation of its material performance, but users often forget to replace it in actual use, which greatly reduces the air purification effect. On the other hand, the HEPA filter screen has limited ability to kill bacteria and viruses in the air, and is high in cost and inconvenient to replace, which also brings certain economic burden. Therefore, it is valuable to research in the direction of air treatment function of the air conditioner. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present application is to provide an air treatment device of an air conditioner, which uses high-temperature steam for humidification, is low in cost and good in user experience.

[0004] The present application also provides an air conditioner.

[0005] The air treatment device of the air conditioner according to the first aspect of the present application comprises a seat body defining a mounting cavity, a humidifying box movably arranged in the mounting cavity and having a humidifying cavity and a steam outlet, the steam outlet being in communication with the humidifying cavity, a water tank for supplying liquid into the humidifying cavity, and a heating element arranged in the humidifying cavity for heating the liquid in the humidifying cavity to form steam. The air treatment device has a steam output port, a first air conveying passage and a second air conveying passage in communication with the steam output port. The first air conveying passage is away from the steam output port relative to the second air conveying passage. The first air conveying passage is in communication with the steam outlet. In the direction of steam output, the maximum cross-sectional dimension of the first air conveying passage perpendicular to the center line of the steam output port is greater than the maximum cross-sectional dimension of the second air conveying passage perpendicular to the center line of the steam output port.

[0006] The air handling device of the air conditioner according to the embodiments of this application has a steam humidification function, thereby improving the humidity of indoor air by steam humidification. At the same time, the high-temperature heating process can inhibit bacterial growth, kill indoor pollutants, and also achieve air settling, which helps to reduce static electricity and dust in the air. This achieves precise control of indoor air quality and improves the user experience. Moreover, this humidification method not only has a faster humidification speed and better humidification effect, but also eliminates the need for a filter, thus reducing the later maintenance costs, reducing the need for frequent cleaning operations, and further improving the user experience.

[0007] Furthermore, by designing the cross-section of the steam outlet, the flow of high-temperature steam narrows as it exits, increasing the steam velocity and thus increasing the steam injection distance. This also reduces the problem of condensate accumulation, thereby avoiding the problem of water blowing caused by condensate accumulation, thus improving the steam output effect and enhancing the user experience.

[0008] In some embodiments, the first gas delivery channel extends upward at a gradually upward angle away from the steam inlet.

[0009] In some embodiments, the air handling apparatus further includes: a first adapter defining a first air supply passage having a steam inlet communicating with the steam outlet; and a second adapter defining a second air supply passage having one side communicating with the first air supply passage and the other side communicating with the steam outlet.

[0010] In some embodiments, the first adapter is a circular tube, and the second adapter is a flat tube located on the radially upward side of the circular tube. This facilitates the backflow of condensate formed at the steam outlet, allowing condensate generated in the first adapter to flow towards the steam inlet, and then along the steam pipe into the humidification box. The condensate can be reheated to form steam, while preventing water spraying at the outlet.

[0011] In some embodiments, the system further includes a fan assembly having an air outlet duct and a fan outlet, the fan outlet being connectable to either indoors or outdoors, wherein the steam outlet is adjacent to the fan outlet. This utilizes the negative pressure created by the airflow from the fan assembly at the steam outlet to rapidly draw steam out of the steam pipe, increasing the steam outflow speed and improving the humidification effect. Furthermore, the proximity of the steam outlet to the fan outlet allows the steam outlet and fan outlet on the air conditioner to be arranged adjacently, facilitating concealed openings and improving structural integrity. In some embodiments, the fan outlet includes an outdoor exhaust vent and an indoor recirculation vent, the outdoor exhaust vent connecting to the outdoors and the indoor recirculation vent connecting to the indoor environment. A movable obstruction is provided within the air outlet duct, the obstruction being used to open one of the outdoor exhaust vent and the indoor recirculation vent.

[0012] In some embodiments, the fan assembly is axially horizontal, the water tank is located on one side of the fan assembly along its axial direction, and the humidification box is located at the bottom of the fan assembly.

[0013] In some embodiments, the humidifier box includes a first box portion, a second box portion, and a third box portion. The second box portion is located on one side of the fan assembly along its axial direction. The first box portion and the third box portion are located at opposite ends of the second box portion and extend towards the fan assembly. The first box portion and the third box portion extend to one side of the fan assembly in a radial direction. This fully utilizes the space inside the base, increasing the capacity of the humidifier box to a certain extent, thereby allowing for a larger heating element and improved steam humidification efficiency.

[0014] In some embodiments, the steam inlet is located above the steam outlet, and the steam inlet is connected to the steam outlet via a steam transmission pipe.

[0015] In some embodiments, the steam pipe is detachably connected to the humidification box, one end of the steam pipe is provided with a connecting member, the humidification box is provided with a steam outlet boss, the steam outlet boss defines the steam outlet, the connecting member is adapted to be inserted into the steam outlet boss and the outer periphery of the connecting member is sealed to the steam outlet boss.

[0016] In some embodiments, the humidifier box includes: a box body defining the humidification chamber; a cover disposed on and detachably connected to the box body, and a heating element disposed on the cover. The heating element can be separated from the box body along with the cover, thereby facilitating cleaning of both the box body and the heating element.

[0017] In some embodiments, the housing is provided with a partition for dividing the humidification chamber into a first chamber and a second chamber with an open top. The partition has a communication port connecting the first chamber and the second chamber. The first chamber has a top post that cooperates with a water tank. The cover is provided on the second chamber for sealing the second chamber.

[0018] An air handling device for an air conditioner according to a second aspect embodiment of this application includes: a base; a humidifier box disposed on the base and having a humidification chamber and a steam outlet, the steam outlet communicating with the humidification chamber; a water tank for introducing liquid into the humidification chamber; a heating element disposed in the humidification chamber for heating the liquid in the humidification chamber to form steam; and a fan assembly having an air outlet duct with a fan outlet that can communicate with indoor or outdoor space, wherein the air handling device has a steam output port communicating with the steam outlet for outputting steam, the steam output port being adjacent to the fan outlet.

[0019] The air handling device of the air conditioner according to the embodiments of this application has a steam humidification function, thereby improving the humidity of indoor air by steam humidification. At the same time, the high-temperature heating process can inhibit bacterial growth, kill indoor pollutants, and also achieve air settling, which helps to reduce static electricity and dust in the air. This achieves precise control of indoor air quality and improves the user experience. Moreover, this humidification method not only has a faster humidification speed and better humidification effect, but also eliminates the need for a filter, thus reducing the later maintenance costs, reducing the need for frequent cleaning operations, and further improving the user experience.

[0020] Furthermore, the high-speed airflow at the fan outlet creates a negative pressure zone in the area before the outlet. Due to the pressure difference, atmospheric pressure pushes the surrounding air towards the outlet area, thereby causing high-temperature water vapor to be quickly discharged from the steam outlet. This is equivalent to drawing steam from the steam pipe, greatly reducing the residence time of the steam in the steam pipe. Thus, the negative pressure created by the airflow of the fan assembly at the steam outlet quickly draws the steam out of the steam pipe, increasing the steam outflow speed and improving the humidification effect.

[0021] In some embodiments, the fan outlet includes an indoor recirculation vent, which is disposed on the fan assembly and communicates with the interior. The steam outlet is adjacent to the indoor recirculation vent. This utilizes the negative pressure created by the airflow from the fan assembly at the steam outlet to rapidly draw steam out of the steam pipe, increasing the steam outflow speed and improving the humidification effect. Furthermore, the proximity of the steam outlet to the fan outlet allows the steam outlet and fan outlet on the air conditioner to be arranged adjacently, facilitating concealed openings and improving structural integrity.

[0022] In some embodiments, the steam outlet is located below the indoor recirculation air vent.

[0023] In some embodiments, the fan assembly further includes an outdoor exhaust vent connected to the outside, and a movable shield is provided in the air outlet duct for opening one of the outdoor exhaust vent and the indoor recirculation vent.

[0024] In some embodiments, the air handling apparatus further includes a first air supply channel and a second air supply channel communicating with the steam outlet. The first air supply channel is located away from the steam outlet relative to the second air supply channel. The first air supply channel is communicating with the steam outlet. In the direction of steam output, the maximum cross-sectional dimension of the first air supply channel perpendicular to the centerline of the steam outlet is greater than the maximum cross-sectional dimension of the second air supply channel perpendicular to the centerline of the steam outlet.

[0025] An air conditioner according to a third aspect of this application includes an air handling apparatus for an air conditioner according to a first or second aspect of this application. By employing the aforementioned air handling apparatus, the user experience can be improved.

[0026] In some embodiments, the air conditioner includes a housing, a portion of which forms the base of the air handling unit, and the humidification box is disposed at the bottom of the housing.

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0053] An air conditioner 200 according to an embodiment of this application includes an air conditioner body and an air handling unit 100. The air conditioner body is an indoor unit, such as a wall-mounted unit or a floor-standing unit. The air conditioner body typically includes structural components such as a fan wheel and a heat exchanger. The heat exchanger is used to exchange heat with the gas flowing through it, thereby realizing the cooling or heating function.

[0054] The air handling unit 100 can be used to purify and humidify gases, thereby improving air quality and humidity.

[0055] An air handling device 100 according to an embodiment of this application includes: a base 10, a humidification box 20, a water tank 30, and a heating element 40. The air handling device 100 has a steam outlet 102. The base 10 defines a mounting cavity 101. The humidification box 20 is movably disposed in the mounting cavity 101. The humidification box 20 has a humidification chamber 201 and a steam outlet 202. The steam outlet 202 communicates with the humidification chamber 201. The water tank 30 is used to introduce liquid into the humidification chamber 201. The heating element 40 is disposed in the humidification chamber 201 and is used to heat the liquid in the humidification chamber 201 to form steam.

[0056] The base 10 is the base of the entire device, providing support and fixation for other components. The humidification box 20 has a humidification chamber 201 inside, which is used to contain liquid. The water tank 30 is used to store liquid. Liquid can be sent into the humidification chamber by gravity or pump. The heating element 40 heats the liquid in the humidification chamber. The steam outlet 202 is the outlet that connects the humidification chamber to the outside. The heated steam is released into the air through this outlet.

[0057] Specifically, the liquid in the water tank 30 is transported into the humidification chamber 201, and the heating element 40 starts to work, heating the liquid in the humidification chamber. As the liquid is heated, it gradually turns into steam, which is released through the steam outlet 202 and then enters the air, thereby increasing the humidity of the air.

[0058] The air handling unit 100 uses this steam humidification method, enabling the air conditioner 200 to have a steam humidification function. This improves indoor air humidity through steam humidification, while the high-temperature heating process inhibits bacterial growth. In addition to killing indoor pollutants, it also promotes air settling, helping to reduce static electricity and dust in the air. This allows for precise control of indoor air quality and improves the user experience. Moreover, this humidification method not only humidifies faster and more effectively, but also eliminates the need for a filter, thus reducing maintenance costs and frequent cleaning operations, further enhancing the user experience.

[0059] When using the steam humidification function, the heating element 40 is turned on, and the high-temperature steam diffuses freely into the external environment. However, the steam outlet distance is short, and condensation is prone to accumulate at the steam outlet, resulting in limited steam output and affecting the humidification effect.

[0060] The air handling unit 100 has a first air supply passage 611 and a second air supply passage 621, which are respectively connected to a steam outlet 102. The first air supply passage 611 is farther away from the steam outlet than the second air supply passage 612. The first air supply passage 611 is connected to a steam outlet 202. Along the direction of steam output, the maximum cross-sectional dimension of the first air supply passage 611 at the center line perpendicular to the steam outlet 102 is greater than the maximum cross-sectional dimension of the second air supply passage 621 at the center line perpendicular to the steam outlet 102.

[0061] Therefore, when high-temperature steam is discharged, its flow cross-section changes from wide to narrow, and the steam velocity increases, which can increase the distance of steam injection. This can also reduce the problem of condensate accumulation, thereby avoiding the problem of water blowing caused by condensate accumulation, thus improving the steam output effect and enhancing the user experience.

[0062] The humidifier box 20 is detachably connected to the base 10. The base 10 defines an installation cavity 101, and the humidifier box 20 is detachably located in the installation cavity 101. For example, a limiting structure is provided on the base 10, such as a snap-fit, slot, or guide rail. This enables the humidifier box 20 to be detachable. After the humidifier box 20 is detached, the inside of the humidifier box 20 and the heating element 40 can be cleaned. This solves the problem that the heating element is enclosed inside the humidification cavity, making it inconvenient to disassemble and impossible to clean thoroughly. Users can more intuitively observe and handle the dirt on the heating element 40.

[0063] In some embodiments, the air handling device 100 further includes a first adapter 61 and a second adapter 62. The first adapter 61 defines a first air delivery passage 611 having a steam inlet 612 communicating with a steam outlet 202. The second adapter 62 defines a second air delivery passage 621, one side of which communicates with the first air delivery passage 611, and the other side of which communicates with a steam outlet 102.

[0064] In some embodiments, the first gas delivery channel 611 extends gradually upward in a direction away from the steam inlet 612, thereby facilitating the return of condensate formed at the steam outlet 102. The condensate generated in the first adapter 61 can flow to the steam inlet 612 and then flow along the steam delivery pipe 11 into the humidification box 20. The condensate can be heated again to form steam, while preventing water spraying at the outlet.

[0065] Among them, the steam transmission pipe 11 is made of a material with certain heat insulation function to reduce the amount of cooling during steam transmission and to deliver more hot steam into the room to a greater extent.

[0066] In some embodiments, the first adapter 61 is a circular tube, and the second adapter 62 is a flat tube located on the radially upward side of the circular tube. The flat tube is connected to the circular tube, and the thickness of the flat tube is less than the diameter of the circular tube, which facilitates the formation of a variable cross-section structure and also facilitates the manufacturing and forming of the adapter structure.

[0067] like Figure 1 and Figure 4 As shown, in some embodiments, the air handling device 100 further includes a fan assembly 50 having an air outlet duct having a fan outlet 53 which can communicate with indoor or outdoor environments, wherein a steam outlet 102 is adjacent to the fan outlet 53.

[0068] The high-speed airflow at the fan outlet 53 creates a negative pressure zone in the area before the outlet. Due to the pressure difference, atmospheric pressure pushes the surrounding air towards the outlet area, thereby driving high-temperature water vapor to be quickly discharged from the steam outlet 102. This is equivalent to drawing steam from the steam pipe 11, greatly reducing the residence time of steam in the steam pipe 11. Thus, the negative pressure formed by the airflow of the fan assembly 50 at the steam outlet 102 quickly draws steam out of the steam pipe 11, increasing the steam outflow speed and improving the humidification effect.

[0069] It should be noted that the fan assembly 50 typically includes a fan, a motor, and a volute. The fan is located inside the volute, and the motor drives the fan to rotate. The axial direction of the fan is the axial direction of the fan assembly 50, and the radial direction of the fan is the radial direction of the fan assembly 50.

[0070] In addition, the air handling unit 100 of the air conditioner 200 typically has the function of introducing fresh air, that is, it has a fresh air fan, and the air handling unit 100 may also have the function of exhausting indoor stale air, that is, it has an exhaust fan.

[0071] The fan assembly 50 here may include an exhaust fan and an exhaust volute. The fan outlet may be an exhaust outlet. When the exhaust fan rotates, indoor air enters the exhaust volute and is then exhausted to the outside through the exhaust outlet.

[0072] In some embodiments, the fan assembly 50 may also include a fresh air fan, and the fresh air volute fan outlet may also be a fresh air outlet. The rotation of the fresh air fan can allow outdoor air to enter the fresh air volute and then be discharged into the room from the fresh air outlet.

[0073] Of course, in some embodiments, an indoor recirculation vent may be included, which may be set on the exhaust volute or the fresh air volute. When set on the exhaust volute, the rotation of the exhaust fan can cause indoor air to pass through the filter and be discharged into the room through the indoor recirculation vent. When set on the fresh air volute, the rotation of the fresh air fan can cause indoor air to pass through the filter and be discharged into the room through the indoor recirculation vent.

[0074] In some specific examples, the air handling unit 100 has an exhaust fan and a fresh air fan, which are axially aligned and arranged side by side. The two fans can be driven by a single motor to rotate two impellers. The air outlet 52 can be located on the exhaust fan's air duct. By utilizing the exhaust fan for air diversion, the fresh air volume will not be affected, ensuring the user's experience.

[0075] The steam outlet 102 is located near the fan outlet 53, so that the steam outlet 102 and the fan outlet 53 on the air conditioner 200 can be arranged in adjacent positions, which facilitates the concealed arrangement of the opening and improves the structural integrity.

[0076] like Figure 4 As shown, in some embodiments, the fan outlet 53 includes an outdoor exhaust vent 531 and an indoor recirculation vent 532. The outdoor exhaust vent 531 is connected to the outside, and the indoor recirculation vent 532 is connected to the inside. A movable shielding member 54 is provided in the air outlet duct. The shielding member 54 is used to open one of the outdoor exhaust vent 531 and the indoor recirculation vent 532. That is, the shielding member 54 can shield the outdoor exhaust vent 531 and open the indoor recirculation vent 532, or the shielding member 54 can shield the indoor recirculation vent 532 and open the outdoor exhaust vent 531.

[0077] For example, when the heating element 40 is working, the shielding element 54 moves to the position of shielding the outdoor exhaust vent 531, at which time the indoor recirculation vent 532 is opened; after the heating element 40 stops working, the shielding element 54 moves to the position of shielding the indoor recirculation vent 532, at which time the outdoor exhaust vent 531 is opened, and the sewage air can be discharged to the outside.

[0078] In some embodiments, the steam outlet 102 is adjacent to the indoor recirculation air outlet 532, thereby utilizing the negative pressure formed at the steam outlet 102 by the airflow of the indoor recirculation air to quickly draw steam out of the steam transmission pipe 11. The high-speed airflow at the indoor recirculation air outlet 532 creates a negative pressure zone in the area before the outlet. Due to the pressure difference, atmospheric pressure pushes the surrounding air towards the outlet area, thereby driving high-temperature water vapor to be quickly discharged from the steam outlet 102. This is equivalent to drawing steam from the steam transmission pipe 11, greatly reducing the residence time of steam in the steam transmission pipe 11.

[0079] In some embodiments, the steam outlet 102 is adjacent to the indoor air circulation vent 532 and is located below the indoor air circulation vent 532. Since steam has an upward tendency, the indoor air circulation vent 532 is located above the indoor air circulation vent 532. The steam mixes with the airflow flowing out of the indoor air circulation vent 532 and can then be discharged into the room with the airflow, thereby improving the steam output effect.

[0080] In some embodiments, the fan assembly 50 is axially horizontal, the water tank 30 is located on one side of the fan assembly 50 along its axial direction, and the humidification box 20 is located at the bottom of the fan assembly 50. This makes full use of the space on the front side of the fan assembly 50 for the installation of the water tank 30, and also makes full use of the space at the bottom of the fan assembly 50 for the installation of the humidification box 20. The humidification box 20 can be pulled out from one side of the fan assembly 50, making disassembly convenient.

[0081] In some embodiments, since the fan assembly 50 is generally cylindrical, there is a certain space between the sides of the fan assembly 50 and the bottom of the base 10. In order to make full use of this space, such as Figure 5 As shown, the humidifier box 20 includes a first box portion 20a, a second box portion 20b, and a third box portion 20c. The second box portion 20b is located on one side of the fan assembly 50 along the axial direction. The first box portion 20a and the third box portion 20c are located at both ends of the second box portion 20b and extend towards the fan assembly 50. The first box portion 20a and the third box portion 20c extend to one side of the fan assembly 50 in the radial direction. This makes full use of the space inside the base 10, increases the capacity of the humidifier box 20 to a certain extent, and can increase the size of the heating element and improve the steam humidification efficiency.

[0082] In some embodiments, the steam inlet 612 is located above the steam outlet 202, and the steam inlet 612 is connected to the steam outlet 202 through the steam pipe 11, so that the steam flows upward and can smoothly enter the channel of the adapter and be discharged smoothly. The condensate formed can flow to the steam outlet 202 and then flow along the steam pipe 11 into the humidification box 20. The condensate can be heated again to form steam.

[0083] like Figure 2 and Figure 3 As shown, in some embodiments, one end of the steam pipe 11 is provided with a connecting piece 111, and the humidification box 20 is provided with a steam outlet boss 24. The steam outlet boss 24 defines the steam outlet 202. The connecting piece 111 can be inserted into the steam outlet boss 24, and the outer periphery of the connecting piece 111 is sealed with the steam outlet boss 24, thereby improving the sealing performance at the connection between the steam pipe 11 and the humidification box 20 and reducing the probability of steam leakage.

[0084] like Figure 6 As shown, in some embodiments, the humidifier box 20 includes: a box body 21 and a cover 22. The box body 21 defines a humidification chamber 201. The cover 22 is disposed on the box body 21 and is detachably connected to the box body 21. The heating element 40 is disposed on the cover 22. The heating element 40 can be separated from the box body 21 along with the cover 22, thereby facilitating both cleaning of the box body 21 and cleaning of the heating element 40.

[0085] For example, the heating element 40 can be fixed to the cover 22 of the humidifier box 20 by screws, and the user can directly and manually clean the scale on the surface of the heating element 40 by lifting the cover 22.

[0086] The heating element 40 is mounted on the top, which can effectively prevent air or water leakage caused by poor sealing or aging of the sealing ring when the heating element 40 is mounted on the bottom.

[0087] like Figure 1 As shown, the humidifier box 20 and the water tank 30 are located in front of the fan assembly 50, with the water tank 30 located above the humidifier box 20, thus making full use of the space in front of the fan assembly 50.

[0088] like Figure 6 As shown, in some examples, the housing 21 is provided with a partition 211 to divide the humidification chamber 201 into a first chamber 2011 and a second chamber 2012 with the top open. The partition 211 has a connecting opening 212 that can connect the first chamber 2011 and the second chamber 2012. The cover 22 is provided on the second chamber 2012 to seal the second chamber 2012. It should be noted that the length of the second chamber 2012 is greater than the maximum length of the heating element 40 so that the heating element 40 can be placed inside the second chamber 2012 when the cover 22 covers the second chamber 2012.

[0089] The first chamber 2011 has a top column 213 that cooperates with the water tank 30. The top column 213 is used to open the water outlet valve at the bottom of the water tank 30, so that the water in the water tank 30 flows into the first chamber 2011. The first chamber 2011 and the second chamber 2012 are interconnected, and the water in the water tank 30 can flow into the second chamber 2012.

[0090] Specifically, the top column 213 contacts the water outlet valve at the bottom of the water tank 30, and the water inside the water tank 30 flows into the humidification box 20. When the water in the humidification box 20 is submerged by the water outlet valve, the water tank 30 and the humidification box 20 form a communicating vessel. At this time, the water level in the humidification box 20 will not change and will always remain submerged by the water outlet valve. When the water in the humidification box 20 is heated by the heating element to generate high-temperature water vapor, the water in the humidification box 20 is consumed, and the water tank 30 simultaneously replenishes water to the humidification box 20 to maintain a constant water level in the humidification box 20.

[0091] like Figure 5 and Figure 6As shown, in some embodiments, the air handling device 100 further includes a water level detector 70, which is disposed on the humidification box 20. A portion of the water level detector 70 extends into the humidification chamber 201 to detect the water level in the humidification chamber 201. The water level detector 70 can control the operation of the heating element 40 according to the detected water level. By setting the water level detector 70, the heating element 40 is prevented from being damaged due to prolonged dry burning.

[0092] The water level detector 70 can be two electrode rods, one long and one short. The two electrode rods form an electrical path in the humidification chamber 201, thereby realizing the monitoring of the water level.

[0093] The water level detector 70 is used to detect the water level in the humidification box. After the water in the water tank 30 is consumed, the heating element 40 continues to work and consume water. When the water level in the humidification chamber 201 is lower than the lowest position of the water level detector 70, the power supply to the heating element 40 is cut off to prevent the heating element 40 from burning dry and causing safety hazards.

[0094] In some embodiments, the air handling unit 100 further includes a protection mechanism located at the steam outlet 202 for detecting steam humidity values. The protection mechanism can control the operation of the heating element 40 based on the detected steam humidity values.

[0095] Specifically, when the water level in the humidifier box 20 drops below the first water level, the heating element 40 stops heating the water inside the cavity. If the heating element 40 malfunctions and continues to heat even after detecting that the water level is below the first water level, the protection mechanism can be triggered. The protection mechanism can then output a power-off signal to the heating element 40 through the control unit based on the detected steam humidity value signal, thus cutting off the power to the heating element 40.

[0096] Of course, the control unit can also output a power-off signal to the heating element 40 based on whether the current signal flowing through the heating element 40 suddenly becomes abnormal, such as a sudden increase in current, so that the heating element 40 is forced to shut down; when the user wants to restart the device, the user is reminded that the heating element 40 is abnormal and needs to be replaced.

[0097] The air conditioner 200 according to an embodiment of this application includes an air handling unit 100 according to the embodiment of the air conditioner 200. By employing the air handling unit 100, the air conditioner 200 has a steam humidification function. Steam humidification improves the humidity of indoor air, and the high-temperature heating process can inhibit bacterial growth. While killing indoor pollutants, it can also achieve air settling, which helps reduce static electricity and dust in the air. This achieves precise control of indoor air quality and improves the user experience. Moreover, this humidification method not only has a faster humidification speed and better humidification effect, but also eliminates the need for a filter. Therefore, it can reduce the later maintenance cost, reduce the frequency of cleaning operations, and further improve the user experience.

[0098] In some embodiments, the air conditioner 200 includes a housing, a portion of which forms the base 10 of the air handling unit 100. A humidifier box 20 is disposed at the bottom of the air conditioner 200, and a water tank 30 may also be disposed at the bottom of the air conditioner 200, thereby facilitating the disassembly and installation of the humidifier box 20 and the water tank 30.

[0099] like Figure 1 As shown, the humidifier box 20 and the water tank 30 are located on the front side of the fan assembly 50, with the water tank 30 located on the top of the humidifier box 20, thereby making full use of the space inside the housing and improving the compactness of the structure.

[0100] Other configurations and operations of the air conditioner 200 according to embodiments of this application are known to those skilled in the art and will not be described in detail here. The vertical, horizontal, and front-back directions are defined as shown in the figures.

[0101] In the description of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0102] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
