Description

Technical Field

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

[0002] An air conditioner, or air conditioner, is a device used to regulate and control indoor environmental parameters (such as temperature, humidity, cleanliness, and airflow) to meet people's needs for a comfortable indoor environment or the requirements of specific processes.

[0003] During air conditioning operation, especially in cooling or heating mode, indoor air humidity may decrease, causing people to feel dry and uncomfortable, and potentially leading to problems such as dry skin and respiratory illnesses. Therefore, air conditioners are equipped with a steam humidification module, which delivers water vapor into the room to increase indoor air humidity and improve indoor comfort.

[0004] In related technologies, steam humidification modules include a humidification chamber and a water tank. The water tank is connected to the humidification chamber to ensure a continuous water supply. A heating element is installed inside the humidification chamber to heat the water, causing it to boil and convert into steam, which is then discharged. However, when the humidification module is idle for an extended period, the residual water in the humidification chamber is prone to mold growth, leading to foul odors and contamination, affecting hygiene during subsequent use. A dry-burning mode is typically used to address this problem. However, this method requires the water in the tank to completely drain and flow into the humidification chamber before the dry-burning mode can be activated. This not only prolongs the self-cleaning process but also results in unnecessary waste of water resources. Utility Model Content

[0005] This application discloses an air conditioner that can start the heating element to dry-burn and clean the humidification chamber without waiting for the water in the water tank to drain, thus shortening the self-cleaning time and avoiding the waste of remaining water in the water tank.

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

[0007] Cabinet unit, the cabinet unit includes:

[0008] chassis;

[0009] A humidification module, disposed within the housing, comprises:

[0010] Humidification chamber;

[0011] A heating element is disposed inside the humidification chamber, and the heating element is used to convert the water in the humidification chamber into water vapor;

[0012] A water tank is movably disposed above the humidification chamber, and the water tank has a water outlet facing the humidification chamber for adding water to the humidification chamber.

[0013] A one-way valve is connected to the water tank and located at the water outlet. The one-way valve is configured to connect the water tank and the humidification chamber after the water tank and the humidification chamber are assembled.

[0014] A drive mechanism is provided for raising and lowering the water tank so that the water tank and the humidification chamber can be assembled or disassembled, and the one-way valve is configured to close when the water tank and the humidification chamber are disassembled.

[0015] Thus, since the water tank is movably located above the humidification chamber, the water tank can be lifted by the drive mechanism, which can close the one-way valve and cut off the water supply. The heating element can be started to dry-burn and clean the humidification chamber without waiting for the water in the tank to run dry, shortening the self-cleaning time and avoiding the waste of residual water in the tank. When the humidification module is not in use, the dry-burn mode can quickly remove residual moisture in the humidification chamber, destroy the mold growth environment, reduce odor and pollution from the source, and improve the hygiene of use.

[0016] Moreover, the mechanical linkage design of the one-way valve eliminates the need for complex electrical control, resulting in a simple structure. Water flow can be controlled solely by the assembly status of the water tank and humidification chamber, reducing the risk of malfunction and simplifying control logic. The self-cleaning process is more efficient, eliminating the need for manual drainage. Furthermore, because the water tank is lifted, there is no contact between the water tank and the humidification chamber, ensuring good insulation. The dry-burning reminder function also indirectly alerts the user to the equipment's idle status, balancing practicality and convenience.

[0017] This application also provides an air conditioner, wherein the humidification chamber includes a water inlet, and a one-way valve top post is provided at the water inlet, wherein the one-way valve top post is arranged opposite to the one-way valve.

[0018] The one-way valve includes:

[0019] Valve body, the valve body being connected to the water outlet;

[0020] The valve core is disposed in the valve body and abuts against the one-way valve top column. The one-way valve top column can push the valve core to open the one-way valve and put the water tank in the water filling position.

[0021] An elastic element is disposed between the valve core and the valve body, and the elastic element is configured to push the valve core to close the one-way valve when the valve core is separated from the one-way valve top post.

[0022] Thus, when the drive mechanism lifts the water tank, causing the check valve's top column to separate from the valve core, the elastic element pushes the valve core back to its original position, automatically closing the water outlet and cutting off the water flow. Dry-burning cleaning can begin without waiting for the tank to drain. When the check valve is closed, it completely blocks water from the tank, allowing the remaining water in the tank to be retained. Only the residual water in the humidification chamber is subjected to dry-burning treatment, avoiding waste of the entire tank of water. This is especially suitable for scenarios with frequent start-stop or intermittent use. This mechanical linkage design provides more precise control, simplifies operation, reduces manufacturing costs and maintenance difficulty, and improves operational stability.

[0023] This application also provides an air conditioner, wherein the drive mechanism includes:

[0024] Electric motor;

[0025] A worm gear is located at the output end of the motor, and the motor can drive the worm gear to rotate.

[0026] A worm gear is connected to the worm shaft via a transmission, and the motor drives the worm shaft to rotate, thereby causing the worm gear to rotate.

[0027] A rack is arranged vertically and is connected to a worm gear drive. When the worm gear rotates, it can drive the rack to rise and fall. The water tank is fixed relative to the rack.

[0028] Thus, the worm gear transmission possesses self-locking properties. The worm can drive the worm wheel, but the worm wheel cannot drive the worm in the reverse direction. Combined with the rigid meshing of the rack and pinion, precise control of the water tank's lifting position is achieved, ensuring a stable clearance between the check valve and its top column. This prevents water leakage or incomplete closure due to positional deviations. The self-locking characteristic of the worm gear transmission allows the rack to maintain its current position during power outages or shutdowns, preventing accidental opening of the check valve due to the water tank falling under gravity and mitigating the risk of leakage during non-operational periods.

[0029] This application also provides an air conditioner, wherein the drive mechanism further includes:

[0030] The lifting part is fixed to the rack and is located below the water tank.

[0031] In this way, the lifting section achieves raising and lowering by supporting the bottom of the water tank, which can distribute the force to a larger area of ​​the bottom of the water tank, avoiding excessive local stress that could cause deformation and leakage, and extending the service life of the components. Moreover, the lifting section can be designed with a structure that matches the contour of the bottom of the water tank, increasing the contact area with the water tank, reducing the shaking or displacement of the water tank during raising and lowering, ensuring the alignment accuracy of the one-way valve and the one-way valve top column, and preventing water circuit control failure due to water tank tilting.

[0032] This application also provides an air conditioner, wherein the rotation axis of the output end of the motor is arranged in a vertical direction, and the rotation axis of the worm gear is arranged in a horizontal direction.

[0033] In this way, the rotation axis of the motor output end is arranged vertically, and the rotation axis of the worm gear is arranged horizontally. This design of vertically intersecting axes allows the motor, worm, and worm gear to be arranged in three-dimensional space, avoiding the stacking of components in a single direction. It can more flexibly adapt to the narrow space inside the cabinet and reduce interference with the layout of other functional modules.

[0034] This application also provides an air conditioner, wherein the housing has a water tank cover, the water tank is movably disposed within the water tank cover, and after the water tank is assembled with the humidification chamber, the top of the water tank is lower than the top of the water tank cover, and at least one side wall of the water tank is fitted to the inner wall of the water tank cover to provide guidance when the water tank is lifted.

[0035] Thus, the water tank cover, as a cavity structure within the casing, provides installation space and protective boundaries for the water tank. Under normal conditions, the water tank is completely contained within the cover, with its top lower than the top of the cover, forming a closed or semi-closed structure. At least one side wall of the water tank is tightly fitted to the inner wall of the water tank cover. The water tank is movably positioned within the water tank cover. When the drive mechanism lifts the water tank via the lifting section, the inner wall of the cover constrains the water tank, forcing it to move vertically and preventing lateral displacement or tilting.

[0036] This application also provides an air conditioner, wherein the water tank cover includes a rear sidewall, the lower part of the rear sidewall forms a groove in the water tank cover, the drive mechanism is disposed in the groove, the groove communicates with the interior of the water tank cover, and the water tank is disposed on the side of the groove.

[0037] In this way, the recessed space at the bottom of the rear side wall accommodates the drive mechanism, avoiding the drive components occupying the main installation area of ​​the water tank, making the overall size of the water tank cover more compact. The groove serves as the mounting position for the drive mechanism, and the transmission components can be positioned through preset fixing holes, reducing assembly errors.

[0038] Meanwhile, the integrated design of the groove and the cover eliminates the need for additional supports, reducing the number of parts and assembly complexity. The groove structure on the rear side wall separates the drive mechanism from the water tank body, reducing the risk of condensation or splashes on the water tank surface directly contacting components such as the motor and gears; at the same time, the sealing of the groove can prevent water vapor generated in the humidification chamber from entering the drive system, improving electrical safety and the durability of transmission components.

[0039] This application also provides an air conditioner, wherein a motor bracket extends from the bottom wall of the groove, the motor is fixed below the motor bracket, the worm gear is located below the output end of the motor, the worm gear is located beside the worm gear, and the rack is located on the side of the worm wheel away from the worm gear.

[0040] In this way, the motor, worm, worm wheel, and rack mesh directly in a straight or perpendicular direction, reducing intermediate transition parts, shortening the power transmission path, and reducing energy loss. In particular, the orthogonal direct meshing of the worm and worm wheel avoids the precision loss caused by multi-gear steering and improves transmission efficiency.

[0041] The vertically stacked motor and worm gear, combined with the horizontally arranged worm wheel and rack, form an L-shaped layout for the entire drive mechanism within the groove. This makes full use of the groove's vertical space and horizontal width, avoids excessive extension in a single direction, and provides more space for the water tank.

[0042] This application also provides an air conditioner, wherein the cabinet unit further includes a fresh air module and an air outlet grille, the fresh air module includes a fresh air outlet, the humidification module includes a humidification outlet, and both the fresh air outlet and the humidification outlet are located at the air outlet grille.

[0043] In this way, both the fresh air outlet and the humidification outlet of the humidification module are located inside the air outlet grille, and the orientation of both outlets is consistent with the airflow direction of the grille, ensuring that the airflow can be smoothly delivered along the direction of the grille blades. The clean fresh air discharged from the fresh air outlet and the water vapor discharged from the humidification outlet are initially mixed in this cavity, and then guided by the airflow blades of the grille to form a mixed air with a suitable temperature, humidity, and sufficient oxygen content, avoiding the discomfort caused by a single fresh air or a single humidified air blowing directly on the user.

[0044] This application also provides an air conditioner, wherein the humidification outlet is located within the fresh air outlet, so that the fresh air from the fresh air outlet can drive the steam from the humidification outlet to be blown out of the air outlet grille.

[0045] Therefore, since steam tends to condense and linger near the humidification outlet when there is no fresh air intake, the humidification outlet is located inside the fresh air outlet. This allows the fresh air from the fresh air outlet to carry the steam from the humidification outlet out of the air grille. When the positive pressure airflow flows through the fresh air outlet, it creates a negative pressure zone inside. The fresh air actively draws the steam from the humidification outlet to diffuse, and the steam mixes with the fresh air inside the outlet, increasing the diffusion speed, preventing condensation and water accumulation around the humidification outlet, and avoiding mold growth.

[0046] Compared with the prior art, the beneficial effects of this application are as follows:

[0047] In this application, since the water tank is movably located above the humidification chamber, the water tank can be raised and lowered by the drive mechanism. After the water tank rises, the one-way valve can be closed to cut off the water supply. The heating element can be started to dry-burn and clean the humidification chamber without waiting for the water in the tank to run dry, which shortens the self-cleaning time and avoids the waste of the remaining water in the water tank. When the humidification module is idle, the residual moisture in the humidification chamber can be quickly removed by the dry-burn mode, destroying the mold growth environment, reducing odor and pollution from the source, and improving the hygiene of use.

[0048] Moreover, the mechanical linkage design of the one-way valve eliminates the need for complex electrical control, resulting in a simple structure. Water flow can be controlled solely by the assembly status of the water tank and humidification chamber, reducing the risk of malfunction and simplifying control logic. The self-cleaning process is more efficient, eliminating the need for manual drainage. Furthermore, because the water tank is lifted, there is no contact between the water tank and the humidification chamber, ensuring good insulation. The dry-burning reminder function also indirectly alerts the user to the equipment's idle status, balancing practicality and convenience. Attached Figure Description

Unless otherwise stated, "a plurality of" means two or more.

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

[0071] During air conditioning operation, especially in cooling or heating mode, indoor air humidity may decrease, causing people to feel dry and uncomfortable, and potentially leading to problems such as dry skin and respiratory illnesses. Therefore, air conditioners are equipped with a steam humidification module, which delivers water vapor into the room to increase indoor air humidity and improve indoor comfort.

[0072] In related technologies, steam humidification modules include a humidification chamber and a water tank. The water tank is connected to the humidification chamber to ensure a continuous water supply. A heating element is installed inside the humidification chamber to heat the water, causing it to boil and convert into steam, which is then discharged. However, when the humidification module is idle for an extended period, the residual water in the humidification chamber is prone to mold growth, leading to foul odors and contamination, affecting hygiene during subsequent use. A dry-burning mode is typically used to address this problem. However, this method requires the water in the tank to completely drain and flow into the humidification chamber before the dry-burning mode can be activated. This not only prolongs the self-cleaning process but also results in unnecessary waste of water resources.

[0073] Based on this, this application provides an air conditioner that can start the heating element to dry-burn and clean the humidification chamber without waiting for the water in the tank to drain, thus shortening the self-cleaning time and avoiding the waste of remaining water in the tank.

[0074] The following will describe specific embodiments and appendices. Figure 1 To be continued Figure 10 The technical solution of the air conditioner in this application is described.

[0075] like Figure 1 and Figure 2As shown, one embodiment of this application provides an air conditioner, which includes a cabinet unit 100. The cabinet unit 100 includes a housing 10 and a humidification module 20, with the humidification module 20 disposed inside the housing 10. The housing 10 serves as the outer shell of the entire cabinet unit 100, providing a mounting carrier for the humidification module 20 and other components, ensuring the stability of component integration, and also possessing a certain degree of decorative appeal to blend into different interior decoration styles.

[0076] like Figure 3 and Figure 5 As shown, the humidification module 20 includes a humidification chamber 21 and a heating element 22. The heating element 22 is disposed inside the humidification chamber 21 and is used to convert the water in the humidification chamber 21 into water vapor. As a core actuator, the heating element 22 is fixed inside the humidification chamber 21 and acts directly on the water in the chamber to generate water vapor.

[0077] It should be explained that when the heating element 22 works, it causes the surrounding water to boil and generate water vapor. Because the water vapor has a low density, it diffuses upward. The top of the humidification chamber 21 is connected to a humidification pipe, through which the water vapor is guided out of the cabinet 100.

[0078] The heating element 22 can be an electric heating element, or it can be a heating tube, a ceramic heating element 22, an electromagnetic induction heating element 22, or other heating elements 22. This application does not limit the specific heating element 22.

[0079] like Figure 4 As shown, the humidification module 20 also includes a water tank 23, which is movably positioned above the humidification chamber 21. The water tank 23 has a water outlet 231 facing the humidification chamber 21, which is used to add water to the humidification chamber 21. The water tank 23 stores water to provide a water source for the generation of water vapor. The water tank 23 replenishes water to the humidification chamber 21 through the water outlet 231 using the principle of gravity water supply. The water tank 23 is movably positioned above the humidification chamber 21, allowing it to be positioned closer to or further away from the humidification chamber 21.

[0080] like Figure 4 and Figure 5 As shown, the humidification module 20 also includes a one-way valve 24, which is connected to the water tank 23 and located at the water outlet 231. The one-way valve 24 is configured to connect the water tank 23 and the humidification chamber 21 after assembly. The one-way valve 24 controls the water supply. When the water tank 23 and the humidification chamber 21 are assembled, the one-way valve 24 opens to connect the water path, and the water level in the humidification chamber 21 is maintained at a preset height, which satisfies the immersion requirement of the heating element 22 while preventing excessive water from overflowing.

[0081] like Figure 3As shown, the humidification module 20 also includes a drive mechanism 30 for lifting the water tank 23 so that the water tank 23 and the humidification chamber 21 can be assembled or separated. The one-way valve 24 is configured to close when the water tank 23 and the humidification chamber 21 are separated.

[0082] Thus, since the water tank 23 is movably located above the humidification chamber 21, the one-way valve 24 can be closed by lifting the water tank 23 through the drive mechanism 30, thereby cutting off the water supply. The heating element 22 can be started to dry-burn and clean the humidification chamber 21 without waiting for the water in the water tank 23 to run dry, shortening the self-cleaning time and avoiding the waste of residual water in the water tank 23. When the humidification module 20 is idle, it can quickly remove residual moisture in the humidification chamber 21 through the dry-burn mode, destroying the mold growth environment, reducing odor and pollution from the source, and improving the hygiene of use.

[0083] Furthermore, the mechanical linkage design of the one-way valve 24 eliminates the need for complex electrical control, resulting in a simple structure. Water flow can be controlled solely by the assembly status of the water tank 23 and the humidification chamber 21, reducing the risk of malfunction and simplifying control logic. The self-cleaning process is more efficient, eliminating the need for manual drainage. Because the water tank 23 is lifted, it does not contact the humidification chamber 21, providing excellent insulation. The dry-burning reminder function also indirectly alerts the user to the equipment's idle status, balancing practicality and convenience.

[0084] In the diagram, the X direction is the horizontal direction, which is the direction of the rotation axis of the worm gear 33; the Y direction is the vertical direction, which is the direction of the rotation axis of the output end of the motor 31.

[0085] In some embodiments, such as Figure 5 As shown, the humidification chamber 21 includes a water inlet, and a one-way valve top post 211 is provided at the water inlet. The one-way valve top post 211 is arranged opposite to the one-way valve 24.

[0086] In some embodiments, such as Figure 4 As shown, the one-way valve 24 includes a valve body, a valve core, and a resilient element. The valve body is connected to the outlet 231. The valve core is located within the valve body and abuts against the one-way valve push rod 211. The one-way valve push rod 211 can push the valve core to open the one-way valve 24 and put the water tank 23 in the water filling position. The resilient element is located between the valve core and the valve body. The resilient element is configured to push the valve core to close the one-way valve 24 when the valve core is separated from the one-way valve push rod 211.

[0087] Thus, a one-way valve top post 211 is provided at the water inlet of the humidification chamber 21, corresponding to the one-way valve 24 at the water outlet 231 of the water tank 23. When the water tank 23 and the humidification chamber 21 are assembled, the valve core abuts against the one-way valve top post 211 and is pushed, overcoming the elastic force of the elastic element, and then opens the water outlet 231, so that the water tank 23 enters the water filling state. The water in the water tank 23 flows into the humidification chamber 21 through the water outlet 231 until the water level reaches the preset position. At this time, the water pressure and the elastic force of the elastic element are balanced, and the one-way valve 24 automatically maintains a slightly open state, continuously replenishing water to compensate for evaporation consumption, ensuring that the heating element 22 always works within the preset water level range. After the heating element 22 is powered on, it converts water into water vapor, which is sent into the room through the humidification outlet.

[0088] When the drive mechanism 30 lifts the water tank 23, causing the one-way valve pin 211 to separate from the valve core, the elastic element pushes the valve core to reset, automatically closing the water outlet 231 and cutting off the water circuit. Dry-burning cleaning can be started without waiting for the water tank 23 to drain. When the one-way valve 24 closes, it completely blocks the water outlet from the water tank 23, allowing the remaining water in the tank to be retained. Only the residual water in the humidification chamber 21 is subjected to dry-burning treatment, avoiding waste of the entire tank of water. This is especially suitable for scenarios with frequent start-stop or intermittent use. This mechanical linkage design provides more precise control, simplifies operation, reduces manufacturing costs and maintenance difficulty, and improves operational stability.

[0089] In some embodiments, such as Figure 6 As shown, the drive mechanism 30 includes a motor 31 and a worm gear 32. The worm gear 32 is located at the output end of the motor 31, and the motor 31 can drive the worm gear 32 to rotate.

[0090] In some embodiments, such as Figure 6 As shown, the drive mechanism 30 also includes a worm wheel 33, which is connected to the worm 32 via a transmission. The motor 31 drives the worm 32 to rotate, thereby causing the worm wheel 33 to rotate.

[0091] In some embodiments, such as Figure 6 As shown, the drive mechanism 30 also includes a rack 34, which is arranged vertically and is connected to the worm gear 33. When the worm gear 33 rotates, it can drive the rack 34 to rise and fall. The water tank 23 is fixed relative to the rack 34.

[0092] Thus, the worm gear 33 and worm 32 transmission has a self-locking property. The worm 32 can drive the worm gear 33, but the worm gear 33 cannot drive the worm 32 in the reverse direction. Combined with the rigid meshing of the gear and rack 34, precise control of the water tank 23's lifting position can be achieved, ensuring a stable clearance between the one-way valve 24 and the one-way valve top column 211, and preventing water leakage or incomplete closure due to positional deviations. The self-locking characteristic of the worm gear assembly allows the rack 34 to maintain its current position when power is off or the machine stops, preventing the one-way valve 24 from accidentally opening due to the water tank 23 falling unexpectedly under gravity, thus preventing the risk of water leakage in non-operating states.

[0093] Furthermore, the worm gear structure can amplify the output torque through a reduction ratio design, ensuring smooth lifting and lowering even as the weight of the water tank 23 increases after it is filled with water, avoiding jamming or stalling, and providing reliable drive for different water level conditions. The meshing transmission between the worm 32 and the worm gear 33 provides smoother transmission, and combined with the uniform speed drive of the motor 31, it can reduce vibration and noise during the lifting and lowering of the water tank 23, improving the user experience. The motor 31 drive can be quickly started and stopped through the electronic control system. When the self-cleaning mode needs to be activated, it can quickly drive the water tank 23 to rise and cut off the water circuit, shortening the response time from command to execution and improving self-cleaning efficiency.

[0094] In other embodiments, the drive mechanism 30 may also be a lead screw nut, chain, belt, etc., which are not limited herein.

[0095] In some embodiments, such as Figure 4 and Figure 6 As shown, the drive mechanism 30 also includes a lifting part 35, which is fixed to the rack 34 and is located below the water tank 23.

[0096] Thus, the lifting part 35 is fixedly connected to the rack 34 and is located below the water tank 23. When the rack 34 moves up and down in the vertical direction, the lifting part 35 moves synchronously with the rack 34, and achieves its lifting action by directly supporting the bottom of the water tank 23.

[0097] Motor 31 drives worm gear 32 to rotate, worm wheel 33 decelerates and rotates, rack 34 moves vertically, lifting part 35 rises and falls synchronously, lifting part 35 pushes or releases water tank 23, water tank 23 separates from or fits with humidification chamber 21, and finally triggers the switching state of one-way valve 24.

[0098] The lifting section 35 achieves lifting and lowering by supporting the bottom of the water tank 23, which can distribute the force to a larger area of ​​the bottom of the water tank 23, avoiding excessive local stress that could cause deformation or leakage of the water tank 23, and extending the service life of the components. Moreover, the lifting section 35 can be designed with a structure that matches the bottom contour of the water tank 23, increasing the contact area with the water tank 23, reducing the shaking or displacement of the water tank 23 during lifting and lowering, ensuring the alignment accuracy of the one-way valve 24 and the one-way valve top column 211, and preventing water circuit control failure due to the tilt of the water tank 23.

[0099] The lifting part 35 and the rack 34 can be fixedly connected by welding, bolting, etc., and this application does not limit the specific method.

[0100] In other embodiments, the rack 34 may also be directly connected to the side or top of the water tank 23, which is not limited here.

[0101] In some embodiments, such as Figure 2 As shown, the rotation axis of the output end of the motor 31 is arranged in the vertical direction, and the rotation axis of the worm gear 33 is arranged in the horizontal direction.

[0102] Thus, the rotation axis of the output end of the motor 31 is arranged in the vertical direction, and the rotation axis of the worm gear 33 is arranged in the horizontal direction. This design of vertically intersecting axes allows the motor 31, worm 32, and worm gear 33 to be arranged in three-dimensional space, avoiding the stacking of components in a single direction. This allows for more flexible adaptation to the narrow space inside the cabinet 100 and reduces interference with the layout of other functional modules.

[0103] In addition, the vertical rotation of the output shaft of the motor 31 directly drives the horizontal worm wheel 33 through the worm 32, eliminating the need for additional reversing gears, simplifying the transmission chain structure, reducing the cumulative error caused by multi-gear meshing, and improving transmission accuracy.

[0104] In some embodiments, such as Figure 9 and Figure 10 As shown, the housing 10 has a water tank cover 12, and the water tank 23 is movably disposed inside the water tank cover 12. After the water tank 23 is assembled with the humidification chamber 21, the top of the water tank 23 is lower than the top of the water tank cover 12. At least one side wall of the water tank 23 is fitted with the inner wall of the water tank cover 12 to provide guidance when the water tank 23 is lifted.

[0105] Thus, the water tank cover 12, as a cavity structure within the housing 10, provides installation space and a protective boundary for the water tank 23. Under normal conditions, the water tank 23 is completely contained within the cover, with its top lower than the top of the cover, forming a closed or semi-closed structure. At least one side wall of the water tank 23 is tightly fitted to the inner wall of the water tank cover 12. The water tank 23 is movably disposed within the water tank cover 12. When the drive mechanism 30 lifts the water tank 23 via the lifting part 35, the inner wall of the cover constrains the water tank 23, forcing it to move vertically and preventing lateral displacement or tilting.

[0106] The water tank cover 12 provides physical protection for the water tank 23, preventing dust and condensate generated by other components inside the cabinet 100 from directly intruding into the surface or interface of the water tank 23. At the same time, the design of the top of the cover being higher than the water tank 23 can prevent foreign objects from falling into the water tank 23, ensuring water quality cleanliness.

[0107] In some embodiments, such as Figure 7 and Figure 8 As shown, the water tank cover 12 includes a rear side wall 121. The lower part of the rear side wall 121 forms a groove 1211 inside the water tank cover 12. The drive mechanism 30 is disposed in the groove 1211. The groove 1211 communicates with the interior of the water tank cover 12. The water tank 23 is disposed on the side of the groove 1211.

[0108] In this way, the recessed space at the lower part of the rear sidewall 121 is used to accommodate the drive mechanism 30, avoiding the drive component from occupying the main installation area of ​​the water tank 23, making the overall size of the water tank cover 12 more compact. The groove 1211 serves as the mounting position for the drive mechanism 30, and the transmission component can be positioned through the preset fixing holes, reducing assembly errors.

[0109] Meanwhile, the integrated design of the groove 1211 and the cover avoids the use of additional supports, reducing the number of parts and assembly complexity. The groove 1211 structure on the rear side wall 121 separates the drive mechanism 30 from the main body of the water tank 23, reducing the risk of condensate or splashes on the surface of the water tank 23 directly contacting the motor 31, gears, and other components; at the same time, the sealing of the groove 1211 can prevent water vapor generated by the humidification chamber 21 from entering the drive system, improving electrical safety and the durability of transmission components.

[0110] In some embodiments, such as Figure 8 As shown, a motor bracket 311 extends from the bottom wall of the groove 1211. The motor 31 is fixed below the motor bracket 311. The worm 32 is located below the output end of the motor 31. The worm 32 is located on the side of the worm wheel 33. The rack 34 is located on the side of the worm wheel 33 away from the worm 32.

[0111] In this way, the motor 31, worm 32, worm wheel 33, and rack 34 mesh directly in a straight or perpendicular direction, reducing intermediate transition parts, shortening the power transmission path, and reducing energy loss. In particular, the orthogonal direct meshing of the worm 32 and worm wheel 33 avoids the precision loss caused by multi-gear steering and improves transmission efficiency.

[0112] The vertically stacked motor 31 and worm 32, together with the horizontally arranged worm wheel 33 and rack 34, form an L-shaped layout of the entire drive mechanism 30 within the groove 1211. This makes full use of the vertical space and horizontal width of the groove 1211, avoids excessive extension in a single direction, and provides more space for the water tank 23.

[0113] The motor 31 is fixed to the bottom wall of the groove 1211 by the motor bracket 311. The relative positions of each transmission component are defined by the structure of the motor bracket 311 and the groove 1211, reducing alignment errors during assembly. This rigid fixing method can suppress vibration offset during transmission, ensure stable meshing clearance of the worm gear 33, worm 32, and gear rack 34, and reduce the risk of abnormal noise and wear.

[0114] The motor bracket 311 extends from the bottom wall of the groove 1211, which can directly transmit the weight of the drive mechanism 30 and the reaction force generated during operation to the water tank cover 12, avoiding deformation caused by localized stress concentration. At the same time, the rack 34 is located on the side of the worm gear 33 away from the worm 32, making the worm gear 33 more evenly stressed and improving the load-bearing stability of the water tank 23.

[0115] In some embodiments, such as Figure 1 As shown, the cabinet unit 100 also includes a fresh air module and an air outlet grille 11. The fresh air module includes a fresh air outlet, and the humidification module 20 includes a humidification outlet. Both the fresh air outlet and the humidification outlet are located at the air outlet grille 11.

[0116] Thus, the fresh air module is integrated inside the casing 10 of the cabinet unit 100, usually near the side wall or back of the cabinet unit 100, to facilitate the introduction of outdoor fresh air. The fresh air module includes a fresh air inlet for connecting to the outside, as well as a fresh air fan, an air filter unit and a fresh air outlet. The fresh air module drives outdoor air through the fresh air fan to filter the air through the filter screen to form clean fresh air, which is finally delivered to the air outlet grille 11 area through the fresh air outlet.

[0117] Both the fresh air outlet and the humidification outlet of the humidification module 20 are located inside the air outlet grille 11. The orientation of both the fresh air outlet and the humidification outlet is consistent with the air guide direction of the air outlet grille 11, ensuring that the airflow can be smoothly delivered along the direction of the air guide blades. The clean fresh air discharged from the fresh air outlet and the water vapor discharged from the humidification outlet are initially mixed in this cavity, and then guided by the air guide blades of the air outlet grille 11 to form a mixed air with a suitable temperature, qualified humidity and sufficient oxygen content, avoiding the discomfort caused by a single fresh air or a single humidified air blowing directly on the user.

[0118] In some embodiments, the humidification outlet is located inside the fresh air outlet, so that the fresh air from the fresh air outlet can drive the steam from the humidification outlet out of the air outlet grille 11.

[0119] Since steam tends to condense and linger near the humidification outlet when there is no fresh air intake, the humidification outlet is located inside the fresh air outlet. This allows the fresh air from the fresh air outlet to carry the steam from the humidification outlet out of the air outlet grille 11. When the positive pressure airflow flows through the fresh air outlet, a negative pressure zone is formed inside. The fresh air actively draws the steam from the humidification outlet to diffuse. The steam and fresh air mix inside the outlet, increasing the diffusion speed, preventing condensation and water accumulation around the humidification outlet, and avoiding mold growth.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
