[0047] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0048] It should be noted that the technical features in the embodiment and optional embodiments of the present invention can be combined with each other under the premise of no conflict.

[0049] The present invention provides an air conditioner, which can be a cabinet air conditioner. The cabinet air conditioner generally may include a shell, a heat exchange device, a humidifying device 10, etc. The heat exchange device and the humidifying device 10 are both arranged inside the shell, and the humidifying device 10 is located below the heat exchange device, making full use of the lower space of the shell, so that the air conditioner has both temperature control and humidification functions.

[0050] Figure 1 is a schematic structural diagram of a humidifying device 10 according to one embodiment of the present invention. Figure 2 is a schematic structural diagram of a humidifying device 10 according to another embodiment of the present invention. Figure 3 Schematic diagram of the positional relationship between the air regulating plate 310 and the washing wheel 200 according to an embodiment of the present invention. Figure 4 FIG. 1 is a schematic diagram of the positional relationship between the air regulating plate 310 and the water washing wheel 200 according to another embodiment of the present invention.

[0051] Reference Figures 1 to 4 The humidifying device 10 includes at least a water tank 100, a water washing wheel 200 and an air regulating plate 310, wherein the water tank 100 defines a receiving chamber having an air inlet 110 and an air outlet 120, the water washing wheel 200 is arranged in the receiving chamber and is configured to humidify the air flow passing through it, and the air regulating plate 310 is arranged opposite to a part of the outer periphery of the water washing wheel 200, and is configured to move in a controlled direction toward or away from the water washing wheel 200 to adjust the gap between the air regulating plate 310 and the water washing wheel 200, thereby changing the air flow rate flowing through the water washing wheel 200.

[0052] In the humidifier device 10 of the embodiment of the present invention, an air regulating plate 310 is disposed relative to a portion of the outer periphery of the water-washing wheel 200. A portion of the airflow entering the water tank 100 can be discharged directly from the water tank 100 through the gap between the water-washing wheel 200 and the air regulating plate 310, while the remaining airflow passes through the water-washing wheel 200 before being discharged from the water tank 100. Because the air regulating plate 310 can move toward or away from the water-washing wheel 200, it can adjust the gap between itself and the water-washing wheel 200, thereby changing the amount of airflow passing through the water-washing wheel 200 and, in turn, the humidification capacity of the humidifier 10.

[0053] Since the humidifying device 10 in this embodiment is applied to an air conditioner, the air inlet 110 is provided in the upper region of one of the side walls of the water tank 100, the air outlet 120 is provided in the top wall of the water tank 100, and the air regulating plate 310 is disposed between the portion of the water washing wheel 200 that faces the air inlet 110. It should be noted that those skilled in the art can readily apply this application to other household appliances, and dispose the air inlet 110 at the front side of the water tank 100, the air outlet 120 at the rear side of the water tank 100, and the air regulating plate 310 above the water washing wheel 200.

[0054] In this embodiment, the water tank 100 is a square box, the air inlet 110 is opened on the front side of the water tank 100, the air outlet 120 is opened on the top of the water tank 100, and the front side of the air outlet 120 can extend to the side wall of the front side of the water tank 100. The washing wheel 200 is arranged adjacent to the air inlet 110 in the accommodating cavity of the water tank 100, and the air regulating plate 310 is located in the area between the washing wheel 200 and the air inlet 110.

[0055] In an optional embodiment of the present invention, a connecting plate 320 is provided at the air inlet 110. The connecting plate 320 extends obliquely downward from the upper end of the air inlet 110 toward the water washing wheel 200. Its first side adjacent to the air inlet 110 is rotatably connected to the water tank 100, and its second side adjacent to the water washing wheel 200 is spaced apart from the water washing wheel 200. This prevents the connecting plate 320 from colliding with the water washing wheel 200 when rotating around its first side, ensuring that the connecting plate 320 has sufficient rotational space. The first side of the air regulating plate 310 is rotatably connected to the second side of the connecting plate 320. The second side of the air regulating plate 310 is adjacent to the air outlet 120, and the gap between the air regulating plate 310 and the water washing wheel 200 is adjusted by rotating relative to the connecting plate 320. That is to say, when the air regulating plate 310 moves toward or away from the washing wheel 200, the connecting plate 320 can always follow the movement, thereby blocking the part between the air regulating plate 310 and the air inlet 110, preventing the air flow in the water tank 100 from flowing out of this part.

[0056] It can be understood that the air regulating plate 310 and the connecting plate 320 are similar to a folded paper sheet. When the air regulating plate 310 moves toward the direction close to the water washing wheel 200, the air regulating plate 310 and the connecting plate 320 stretch out. When the air regulating plate 310 moves toward the direction away from the water washing wheel 200, the air regulating plate 310 and the connecting plate 320 fold together.

[0057] In some embodiments, a hinge axis is provided on the first side of the connecting plate 320, with both ends of the hinge axis being hinged to the inner walls of the water tank 100. A hinge axis is provided on the second side of the connecting plate 320, and the first side of the air regulating plate 310 and the second side of the connecting plate 320 are hingedly connected via the hinge axis. Of course, the hinge connection between the first side of the connecting plate 320 and the side wall of the water tank 100, and between the second side of the connecting plate 320 and the first side of the air regulating plate 310, can be implemented in a variety of ways, and those skilled in the art can configure them at their own discretion.

[0058] A sliding rod 330 may be provided on the second side of the air regulating plate 310. Sliding holes 130 are provided on the side walls of the water tank 100 opposite the ends of the sliding rod 330. The sliding holes 130 extend from the air inlet side to the windward side, and the ends of the sliding rod 330 are respectively slidably connected within the sliding holes 130. With this arrangement, by sliding the sliding rod 330 back and forth within the sliding holes 130, the sliding rod 330 can drive the air regulating plate 310 to move toward or away from the washing wheel 200, resulting in a relatively simple and convenient structure.

[0059] When the air inlet 110 is located at the front of the water tank 100, the sliding rod 330 extends leftward and rightward along the second side edge of the air regulating plate 310, and the sliding holes 130 are respectively located on the left and right side walls of the water tank 100. When the sliding rod 330 is slid forward, the sliding rod 330 drives the air regulating plate 310 forward, increasing the gap between the air regulating plate 310 and the washing wheel 200, reducing the amount of air flowing through the washing wheel 200, and thus slowing the humidification speed. When the sliding rod 330 is moved backward, the sliding rod 330 drives the air regulating plate 310 backward, decreasing the gap between the air regulating plate 310 and the washing wheel 200, increasing the amount of air flowing through the washing wheel 200, and thus speeding up the humidification speed.

[0060] It is understood that the humidifier 10 of the present invention adjusts the amount of humidification by simply adjusting the amount of air flowing through the water-washing wheel 200. The greater the amount of air flowing through the water-washing wheel 200 per unit time, the greater the contact area between the air and the water-washing wheel 200, the more air is humidified, and the greater the humidification amount. During the process of adjusting the humidification amount, the total amount of airflow flowing through the water tank 100 per unit time is not affected, that is, the normal cooling and heating speeds of the air conditioner are not affected. The humidification amount is adjusted while ensuring normal temperature control of the air conditioner.

[0061] In an optional embodiment of the present invention, a drive assembly 400 is provided at at least one end of the sliding rod 330. The drive assembly 400 is configured to drive the sliding rod 330 to move within the sliding hole 130, thereby driving the rotation of the air regulating plate 310 relative to the connecting plate 320. The provision of the drive assembly 400 can make the position adjustment of the air regulating plate 310 more convenient, improve the user experience, and enhance the brand's reputation.

[0062] For example, when the air inlet 110 is located on the front side of the water tank 100, the drive assembly 400 may be provided only on the left end of the sliding rod 330, or only on the right end of the sliding rod 330, or both on the left and right ends of the sliding rod 330, with both sets of drive assemblies 400 simultaneously driving the sliding of the sliding rod 330. Since only one set of drive assemblies 400 is required to achieve the sliding of the sliding rod 330 in actual applications, in order to simplify the structure of the humidifier 10 and reduce the cost and energy consumption of the humidifier 10, in this embodiment, the drive assembly 400 is only shown on the left side of the water tank 100.

[0063] Figure 5 is a schematic structural diagram of a drive assembly 400 according to one embodiment of the present invention, Figure 6 1 is a schematic exploded view of a water tank 100 , an air damper 310 , and a driving assembly 400 according to an embodiment of the present invention.

[0064] Reference Figure 5 and Figure 6 The drive assembly 400 may include a slide rail 410, a slider 420, and a motor 430. The slide rail 410 may be fixed to the side wall of the water tank 100, and the slider 420 may be slidably connected to the slide rail 410. The side of the slider 420 adjacent to the sliding rod 330 is rotatably connected to the sliding rod 330. A rack 440 is provided on the side of the slider 420 away from the sliding rod 330. A gear 450 is connected to the output shaft of the motor 430, and the gear 450 is engaged with the rack 440. When the motor 430 is in operation, the engagement of the gear 450 with the rack 440 drives the slider 420 to move along the slide rail 410, thereby causing the slider 420 to drive the air regulating plate 310 to move through the sliding rod 330.

[0065] When the air inlet 110 is opened on the front side of the water tank 100, the sliding rod 330 extends along the left and right directions of the water tank 100, and the sliding rail 410 can be fixed on the outer side of the left or right side wall of the water tank 100 and extends along the front and back directions of the water tank 100. The slider 420 is slidably connected to the sliding rail 410, and a rack 440 extending along the front and back directions is formed on the side of the slider 420 away from the sliding rod 330. The output shaft of the motor 430 is arranged along the height direction of the water tank 100, and the gear 450 is fixed on the output shaft of the motor 430 and meshes with the rack 440.

[0066] To facilitate the installation of the motor 430, in this embodiment, the side wall of the water tank 100 is recessed toward the interior of the water tank 100 to form a mounting platform 140, and the motor 430 can be placed on the mounting platform 140, and its output shaft is arranged upward so that the gear 450 connected to the output shaft can engage with the rack 440.

[0067] In an optional embodiment of the present invention, the slide rail 410 may include a first slide rail and a second slide rail, the first slide rail and the second slide rail are arranged up and down, a first slide groove is provided at the top of the first slide rail, and a second slide groove is provided at the bottom of the second slide rail, and a first plug block and a second plug block are provided on the side of the slider 420 adjacent to the slide rail 410, and the first plug block and the second plug block are respectively slidably connected in the first slide groove and the second slide groove so that the slider 420 clamps the first slide rail and the second slide rail as a whole, and the sliding hole 130 should be located between the first slide rail and the second slide rail, and an end block 460 is fixed on the side of the slider 420 adjacent to the sliding rod 330, and the end of the sliding rod 330 passes through the sliding hole 130 and is rotatably connected in the end block 460.

[0068] In another optional embodiment of the present invention, the drive assembly 400 may include a slide rail 410, a slider 420 and a motor 430, wherein the slide rail 410 can be fixed to the side wall of the water tank 100, the slider 420 can be slidably connected to the slide rail 410, and the slider 420 is rotatably connected to the sliding rod 330 on one side adjacent to the sliding rod 330. The motor 430 is a linear motor 430, and its output shaft is fixedly connected to the slider 420, for driving the slider 420 to move along the slide rail 410, and then driving the air regulating plate 310 to move through the sliding rod 330.

[0069] The washing wheel 200 may include an axle 210 and a plurality of blades 220. The axle 210 is rotatably supported at both ends by the sidewalls of the water tank 100. The blades 220 are connected to the axle 210 at intervals along its length. When the water tank 100 is filled with humidifying water, a water film forms between adjacent blades 220, which helps improve the humidification effect when air flows through. The axle 210 can be driven to rotate by various drive components, which are well known to those skilled in the art and will not be described in detail here.

[0070] When the air inlet 110 is opened on the front or rear side of the water tank 100, the axle 210 should be set horizontally along the left and right directions of the water tank 100. When the air inlet 110 is opened on the left or right side of the water tank 100, the axle 210 should be set horizontally along the front and back directions of the water tank 100 to ensure that the airflow entering the water tank 100 from the air inlet 110 can be blown more directly into the gap between adjacent blades 220.

[0071] It should be noted that during operation of the humidifier 10, the water washing wheel 200 rotates. When moving the air regulating plate 310, attention should be paid to the gap between the air regulating plate 310 and the water washing wheel 200 to prevent collision between the air regulating plate 310 and the water washing wheel 200. In particular, in this embodiment, by precisely designing the length of the sliding hole 130, when the sliding rod 330 slides to the end (rear end) of the sliding rod 330, the air regulating plate 310 is closest to the water washing wheel 200. At this time, the gap between the air regulating plate 310 and the water washing wheel 200 is 3 mm, effectively preventing collision between the air regulating plate 310 and the water washing wheel 200.

Figure 7-9 As shown, the humidifying device further includes a fan 500, which is arranged at the air outlet of the water tank. To facilitate the subsequent distinction between the air inlets and air outlets, the air inlet and air outlet of the water tank 100 are referred to as the first air inlet and the first air outlet.

[0073] The humidifier 10 also includes a fan base 600, which is fixedly mounted on the top of the water tank. The overall shape of the fan base 600 matches the shape of the water tank's top wall. The fan base 600 is provided with a second air inlet 610, which is located opposite and connected to the first air outlet. The second air inlet 610 is mesh-shaped. A plurality of first connection holes 620 are disposed around the fan base 600. The fan 500 is fixedly mounted on the fan base 600 and has a third air inlet 510 and a second air outlet 520. The third air inlet 510 is located on the bottom wall of the fan 500 and corresponds to and connects to the second air inlet 610. The second air outlet 520 is located on the side wall of the fan 500 and is connected to the external environment. A plurality of connecting portions 530 are formed around the outer wall of the fan 500, each of which is provided with a second connection hole 531. The plurality of first connection holes 620 and the plurality of second connection holes 531 correspond to each other one by one, and screws pass through the corresponding second connection holes 531 and first connection holes 620 in sequence to fix the fan 500 and the fan base 600 together.

[0074] Figure 10 FIG is a schematic structural block diagram of a control device for a humidifying device according to an embodiment of the present invention. Figure 10As shown, the control device 20 includes a memory 700 and a processor 800. The memory 700 stores a machine executable program 710. When the machine executable program 710 is executed by the processor 800, any of the following control methods for a humidifying device can be implemented.

[0075] The control device 20 can be disposed within the humidifier 10 as part of the humidifier 10, connected to the humidifier 10's controller via a data link, and operate in conjunction with the humidifier 10's controller. The control device 20 can also be disposed externally to the humidifier 10, for example, on a server, cloud-based network device, or other network-side device, connected to the humidifier 10 via a data link. For example, the control device 20 can also be disposed in the user's environment or the user's surrounding environment, and the connection method with the humidifier 10 includes, but is not limited to, wireless transmission, infrared transmission, ultrasonic transmission, and the like.

[0076] Figure 11 FIG is a flow chart of a control method for a humidifying device according to an embodiment of the present invention. Figure 11 As shown, the control method of the humidifying device may include at least the following steps S1102-S1106.

[0077] Step S1102: Obtain and determine whether the humidity of the room where the humidifier is located is less than a set humidity threshold.

[0078] Step S1104: If yes, control the humidifier to turn on, and if the humidity is greater than the first preset humidity threshold and less than the second preset humidity threshold, obtain human body information in the room to determine whether there is a resting human body in the room.

[0079] Step S1106: If yes, adjust the fan speed to the first speed, and adjust the gap between the air regulating plate and the washing wheel to the first gap, wherein the first speed is the preset minimum speed, the first gap is the preset minimum gap, and the first gap corresponds to the maximum air flow.

[0080] In an embodiment of the present invention, the humidity of the room where the humidifier is located is first obtained and determined to be less than a set humidity threshold. If so, the humidifier is controlled to turn on. If the humidity is greater than a first preset humidity threshold and less than a second preset humidity threshold, human body information in the room is obtained. If a resting human body is present in the room, the fan speed is adjusted to a first speed, and the gap between the air regulating plate and the water washing wheel is adjusted to a first gap. The first speed is a preset minimum speed, the first gap is a preset minimum gap, and the first gap corresponds to the maximum airflow rate. This ensures that the operating noise is low while meeting the humidification requirements, does not affect the user's rest, and improves the user experience.

[0081] In some embodiments of the present invention, a humidity detection device is provided on the housing of the humidifying device, and the step of obtaining the humidity of the room where the humidifying device is located includes: obtaining the humidity of the room where the humidifying device is located collected by the humidity detection device.

[0082] Wherein, the humidity detection device may optionally be a humidity sensor.

[0083] In some embodiments of the present invention, a human body detection device is further provided on the housing of the humidifying device, and the step of obtaining human body information in the room includes: obtaining human body information in the room detected by the human body detection device.

[0084] Optionally, the human body detection device is an image acquisition device or an infrared thermal imager.

[0085] When the human body detection device is an image acquisition device, the step of obtaining human body information in the room detected by the human body detection device includes: obtaining an image captured by the image acquisition device and recognizing the image to obtain human body information.

[0086] Recognizing images and obtaining information therein is a relatively mature technology in this field and will not be described in detail here.

[0087] The human body information may include human body posture, facial information, etc. When the human body information obtained by recognizing the image is at least one of lying, sitting, and closing eyes, it is determined that the human body is in a resting state.

[0088] When the human body detection device is a thermal imager, similarly, if the collected human body information is sitting or lying, it is determined that the human body is in a resting state.

[0089] In some embodiments of the present invention, after the step of controlling the humidification device to turn on, the method further includes: if the room humidity is less than or equal to a first preset humidity threshold, adjusting the fan speed to a second speed, and adjusting the gap between the air regulating plate and the water washing wheel to a first gap, wherein the second speed is a preset maximum speed.

[0090] Among them, if the room humidity is less than or equal to the first preset humidity threshold, it means that the room humidity is very low. At this time, the fan speed is adjusted to the preset maximum speed, and the gap between the air regulating plate and the water washing wheel is adjusted to the first gap corresponding to the maximum air flow, so as to quickly reduce the room humidity.

[0091] In some embodiments of the present invention, after the step of controlling the humidification device to turn on, the method further includes: if the room humidity is greater than or equal to the second preset humidity threshold and less than or equal to the set humidity threshold, adjusting the fan speed to the first speed, and adjusting the gap between the air regulating plate and the water washing wheel to the second gap, wherein the second gap is the preset maximum gap, and the second gap corresponds to the minimum air flow.

[0092] Among them, the room humidity is greater than or equal to the first preset humidity threshold and less than or equal to the set humidity threshold. The room humidity is relatively high. At this time, the fan speed is adjusted to the preset minimum speed, and the gap between the air regulating plate and the water washing wheel is adjusted to the second gap corresponding to the minimum air flow. The humidification mode is softer and less noisy, which improves the user experience.

[0093] In some embodiments of the present invention, after the step of obtaining human body information in the room, the method further includes: if there is no human body in the room or all the existing human bodies are in an active state, adjusting the speed of the fan to a second speed, and adjusting the gap between the air regulating plate and the water washing wheel to a second gap, wherein the second speed is a preset maximum speed, the second gap is a preset maximum gap, and the second gap corresponds to the minimum air flow.

[0094] Among them, when the room humidity is greater than the second preset humidity threshold and less than the second preset humidity threshold, if there is no human body in the room or all the existing human bodies are in an active state, the user's perception of noise will be relatively light. At this time, the fan speed is adjusted to the second speed, and the gap between the air regulating plate and the water washing wheel is adjusted to the second gap for humidification.

[0095] In addition, after controlling the humidifying device to turn on, the method further includes: when the room humidity is greater than or equal to a third preset humidity threshold, adjusting the humidifying device to a standby state, wherein the third preset humidity threshold is greater than the set humidity threshold.

[0096] When the room humidity is greater than or equal to a third preset humidity threshold, the humidifier is adjusted to a standby state, and the third preset humidity threshold is greater than the set humidity threshold, thereby avoiding frequent opening and closing of the humidifier.

[0097] The preset maximum gap corresponds to the maximum displacement of the slider along the slide rail toward the water washing wheel, and the preset minimum gap corresponds to the maximum displacement of the slider along the slide rail toward the water washing wheel.

[0098] The present invention provides a control method and control device for a humidifier. In the control method proposed in the present invention, it is first determined whether the humidity of the room where the humidifier is located is less than a set humidity threshold. If so, the humidifier is controlled to turn on. If the humidity is greater than a first preset humidity threshold and less than a second preset humidity threshold, human body information in the room is obtained. If a person is resting in the room, the fan speed is adjusted to a first speed, and the gap between the air regulating plate and the water washing wheel is adjusted to a first gap. The first speed is a preset minimum speed, the first gap is a preset minimum gap, and the first gap corresponds to the maximum airflow rate. This ensures that the operating noise is low while meeting the humidification requirements, does not affect the user's rest, and improves the user experience.

[0099] Furthermore, if the room temperature is less than or equal to the first preset humidity threshold, the fan speed is adjusted to the second speed, and the gap between the air regulating plate and the washing wheel is adjusted to the first gap, wherein the second speed is the preset maximum speed, so that the room humidity can be reduced as quickly as possible.
