Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a waterless humidification device and a heat pump air conditioner. Background Technology

[0002] As people's living standards improve, their demands for indoor environmental comfort are becoming increasingly stringent. In winter, heating becomes a major concern, and heat pump air conditioners, with their high efficiency and energy savings, have gained widespread use. However, in actual use, users commonly report that indoor air becomes excessively dry. Suitable indoor humidity not only improves human comfort but also benefits health, reducing the occurrence of respiratory illnesses and dry skin. An overly dry environment not only reduces human comfort but may also trigger health problems such as throat inflammation, seriously impacting people's quality of life.

[0003] Existing heat pump air conditioners typically use ultrasonic humidification technology to improve indoor air humidity. However, this humidification method requires users to frequently add water to the ultrasonic humidifier, which is extremely inconvenient. Furthermore, its humidification effect is greatly affected by water quality. If the water quality is poor, the ultrasonic humidifier is prone to burnout, which not only increases the user's operating costs but may also pose safety hazards.

[0004] Therefore, it is necessary to improve the existing humidification method of heat pump air conditioners to overcome the shortcomings of the existing technology. Summary of the Invention

[0005] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a waterless humidification device. This device can absorb moisture from the outside air using a moisture absorption plate and release the absorbed moisture into the indoor environment, thereby achieving waterless automatic humidification and overcoming the defect that requires users to manually add water to the humidifier.

[0006] A waterless humidification device, comprising:

[0007] A housing, wherein a substrate and a moisture-absorbing disc are disposed in the housing, the moisture-absorbing disc being disposed on the substrate, and the moisture-absorbing disc comprising silica gel and molecular sieve;

[0008] The housing is provided with a first airflow channel and a second airflow channel. The first airflow channel includes a first air inlet and a first air outlet, and the second airflow channel includes a second air inlet and a second air outlet. Both the first airflow channel and the second airflow channel are connected to the moisture absorption tray.

[0009] This device can be used in air conditioners. In one specific embodiment, the first air inlet of the first airflow channel is located on the outer casing of the air conditioner near the outdoor unit, while the first air outlet opens to the outside. During dehumidification, cool outdoor air enters through the first air inlet, absorbs moisture through the dehumidification plate, and is then discharged from the first air outlet. The second air inlet of the second airflow channel communicates with the indoor air and is located inside the air conditioner near the cross-flow fan blades. The second air outlet is located on the indoor side with an optimized angle to ensure that the humidified air can be evenly diffused to all corners of the room. During humidification, warm indoor air enters through the second air inlet, is dehumidified by the dehumidification plate, and the moisture-laden air is blown out from the second air outlet, thus humidifying the room. This waterless humidification device automatically absorbs moisture from the outdoor air through the dehumidification plate and releases it into the room when needed, completely avoiding the hassle of manually adding water. Users no longer need to worry about the humidifier running out of water and causing humidification interruption, greatly improving the user experience. For example, during indoor heating in winter, users do not need to get up frequently to add water to the humidifier and can enjoy a comfortable humidified environment continuously.

[0010] In addition, the device is connected to an air source at a specific temperature through a first airflow channel and a second airflow channel, with a clear division of labor. This design allows the moisture absorption and dehumidification processes to proceed in an orderly manner, enhancing the stability of the waterless humidifier's operation.

[0011] In a preferred embodiment of this invention, the first airflow channel is used to communicate with a low-temperature air source, and the second airflow channel is used to communicate with a high-temperature air source; a filter screen is provided at the first air inlet and / or the second air inlet.

[0012] The filters effectively filter the air entering the airflow channel. In one usage configuration, the filter at the first air inlet intercepts dust, pollen, impurities, and other contaminants from the outside air, preventing them from entering the moisture absorption tray and clogging its pores. This ensures the moisture absorption tray maintains excellent moisture absorption and dehumidification performance, extending its lifespan. The filter at the second air inlet filters dust from the circulating indoor air, ensuring cleaner humidified air, improving indoor air quality, reducing respiratory problems caused by inhaled dust, and protecting user health.

[0013] In a preferred embodiment of this invention, a heating device is provided at the second air inlet.

[0014] The heating device raises the temperature of the air entering the second airflow channel. Because the molecular sieve in the moisture-absorbing tray has high-temperature dehumidification properties, heated air allows the tray to release stored moisture more quickly and completely. In winter, when indoor heating is needed, the ambient temperature is relatively low, and relying solely on room-temperature air flowing through the moisture-absorbing tray for dehumidification may be inefficient. Raising the air temperature through the heating device significantly accelerates the dehumidification speed of the tray, increases humidification capacity, and allows the indoor humidity to reach a suitable level more quickly, meeting people's needs for rapid indoor humidity regulation and improving user comfort.

[0015] In addition, the heating device allows for flexible control of the air temperature entering the dehumidification tray by adjusting its power or temperature settings. When indoor humidity is low and a rapid increase in humidity is needed, the power of the heating device can be appropriately increased to raise the air temperature, thereby increasing the dehumidification capacity of the dehumidification tray and enhancing the humidification effect. When indoor humidity is close to the suitable range, the power of the heating device can be reduced to decrease the dehumidification capacity of the dehumidification tray and prevent excessive indoor humidity. This flexible adjustment method can better adapt to different indoor environments and user needs, achieving precise control of indoor humidity.

[0016] In a preferred embodiment of this invention, a plurality of weight sensors are provided at the bottom of the substrate.

[0017] In this embodiment, the weight sensor can directly measure the weight change of the moisture absorption tray, accurately obtaining the amount of moisture absorbed or released by the tray through real-time monitoring. Since the moisture absorption tray increases in weight during absorption and decreases in weight during desiccation, the weight sensor can convert these weight changes into electrical signals, which are then transmitted to the air conditioner's control system. Based on the weight data, the control system can more accurately determine the working status of the moisture absorption tray, such as whether it has reached its maximum absorption capacity or whether the desiccation process is complete. Based on the precise data provided by the weight sensor, the air conditioner's humidity control logic can be further optimized. The control system can more intelligently control the opening and closing times and operating duration of the air inlets and outlets of the first and second airflow channels based on the real-time weight of the moisture absorption tray.

[0018] The second objective of this utility model is to provide a heat pump air conditioner, including the waterless humidification device described above.

[0019] In a preferred embodiment of this utility model, the device includes a main body, a fresh air device is provided inside the main body, the fresh air device is provided with a first airflow channel and a second airflow channel, and the waterless humidification device is provided in the fresh air device.

[0020] This embodiment integrates the waterless humidifier into the fresh air unit, which is itself located within the heat pump air conditioner unit. This highly integrated design effectively saves space. Furthermore, the integrated design reduces the number of connecting parts between devices, lowering the probability of malfunctions and improving overall stability and reliability. The combination of the humidifier and fresh air unit not only regulates indoor humidity but also improves indoor air quality. In winter, it solves the problem of indoor dryness while ensuring fresh indoor air, creating a more comfortable and healthy indoor environment for users.

[0021] In a preferred embodiment of this invention, a guide plate and a first driving device are provided at the second air outlet. The guide plate is rotatably disposed at the second air outlet, and the first driving device is used to drive the guide plate to rotate.

[0022] The air deflector rotates under the action of the first drive device, flexibly changing the airflow direction of the second air outlet to evenly guide the humidified air to every corner of the room. In practical use cases, the distribution of people and their usage needs vary in different areas of a room. The rotatable air deflector can target the delivery of humidified air to where it is needed. For example, in a living room where people's activity areas are relatively dispersed, adjusting the angle of the air deflector can ensure that all areas, such as the sofa area and dining area, receive appropriate humidity, avoiding situations where the humidity is too high or too low in some areas, effectively improving the overall uniformity of indoor humidity and optimizing the user experience.

[0023] In addition, properly adjusting the angle of the air guide plate helps improve the efficiency of the waterless humidification function of the heat pump air conditioner. By precisely guiding the humidifying airflow, excessive air accumulation in local areas or the creation of humidification dead zones are avoided, allowing the moisture released by the moisture absorption plate to be more effectively diffused into the indoor space, reducing energy waste and improving humidification efficiency.

[0024] In a preferred embodiment of this invention, both the first air inlet and the second air inlet are provided with an adjustment mechanism. The adjustment mechanism includes a baffle and a second driving device. The baffle is rotatably disposed at the air inlet, and the second driving device is fixed outside the air inlet and drives the baffle to rotate.

[0025] In this embodiment, the second driving device drives the baffle to rotate, which can precisely adjust the size of the air inlet opening and thus precisely control the airflow entering the first and second airflow channels. During the dehumidification stage, when the outside air humidity is high, the opening of the first air inlet baffle can be appropriately reduced to decrease the amount of air entering and prevent the dehumidification plate from absorbing too much moisture, thus affecting the subsequent dehumidification effect. During the humidification stage, the opening of the second air inlet baffle is adjusted according to the indoor humidity requirements and the dehumidification capacity of the dehumidification plate to control the flow of warm indoor air entering, so that the dehumidification speed of the dehumidification plate matches the indoor humidification requirements, achieving precise regulation of indoor humidity.

[0026] Different usage environments and operating conditions require different airflow rates at the air inlet. In cold winter regions, where outdoor air temperatures are very low, the intake air volume can be reduced by adjusting the first air inlet baffle to prevent excessive cold air from entering and affecting the indoor temperature. In humid summer regions, the opening of the first air inlet baffle can be appropriately enlarged to improve moisture absorption efficiency. Similarly, in situations where there are many people indoors and humidity demands vary significantly, the second air inlet baffle can be flexibly adjusted to meet real-time humidification needs. This adaptability allows waterless humidifiers and heat pump air conditioners to operate stably and efficiently under various complex operating conditions and environments.

[0027] In a preferred embodiment of this invention, a humidity sensor is provided at the bottom of the main body.

[0028] In a preferred embodiment of this invention, the main body is provided with a controller, which is electrically connected to the humidity sensor and the second driving device.

[0029] A humidity sensor is installed at the bottom of the main unit to effectively obtain relatively accurate indoor humidity information. The bottom area typically has relatively stable airflow and is less affected by local airflow or temperature changes. The humidity sensor can reliably monitor the overall indoor humidity, avoiding measurement errors caused by airflow disturbances and providing a reliable data foundation for subsequent humidity adjustment. The controller, humidity sensor, and second drive unit are electrically connected to form an intelligent control system. The humidity sensor transmits real-time indoor humidity data to the controller, which analyzes and judges based on preset humidity thresholds. When the indoor humidity is lower than the set lower limit, the controller sends a command to the second drive unit to actuate the baffles at the first and second air inlets, adjusting the size of the air inlets. For example, reducing the opening of the first air inlet baffle reduces the entry of dry outside air; increasing the opening of the second air inlet baffle allows more indoor air to flow through the dehumidification tray for dehumidification and humidification, thereby increasing indoor humidity. Conversely, when the indoor humidity is higher than the set upper limit, the controller controls the second drive unit to perform the opposite operation to maintain indoor humidity within a comfortable range, achieving automatic and precise adjustment of indoor humidity.

[0030] The beneficial effects of this utility model are as follows:

[0031] This utility model provides a waterless humidifier, which includes a shell containing a substrate and a moisture-absorbing plate. The moisture-absorbing plate is disposed on the substrate and comprises silica gel and molecular sieves. The shell contains a first airflow channel and a second airflow channel. The first airflow channel includes a first air inlet and a first air outlet, and the second airflow channel includes a second air inlet and a second air outlet. Both the first and second airflow channels are connected to the moisture-absorbing plate. This waterless humidifier can be used in air conditioners. In actual use, the first airflow channel connects to the outside air, and the second airflow channel connects to the indoor environment where the air conditioner is used. During use, cold outside air is introduced into the moisture-absorbing plate through the first air inlet, absorbs moisture, and is then discharged from the first air outlet. When humidification is needed, warm indoor air enters the moisture-absorbing plate through the second air inlet, causing the plate to dehumidify. The moisture-laden air is then blown out from the second air outlet, thus humidifying the room. This device automatically absorbs moisture from the outside air using a moisture-absorbing disc and releases it into the room when needed, completely eliminating the hassle of manually adding water. Users no longer need to worry about the humidifier running out of water and interrupting humidification, thus meeting users' indoor humidity needs and improving the user experience.

[0032] This application also provides an air conditioner that includes the above-mentioned waterless humidification device. The air conditioner is easy to use, can effectively regulate the temperature and humidity of the environment, and integrates a waterless humidification device. It has a compact overall structure, low production cost, and helps to improve the user experience. Attached Figure Description

[0040] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0041] Existing heat pump air conditioners typically use ultrasonic humidification technology to improve indoor air humidity. However, this humidification method requires users to frequently add water to the ultrasonic humidifier, which is extremely inconvenient. Furthermore, its humidification effect is greatly affected by water quality. If the water quality is poor, the ultrasonic humidifier is prone to burnout, which not only increases the user's operating costs but may also pose safety hazards.

[0042] Based on this, this application provides a waterless humidification device.

[0043] Example 1

[0044] like Figure 1 As shown, this embodiment provides a waterless humidification device, comprising:

[0045] The housing 1 contains a substrate 22 and a moisture-absorbing disk 21. The moisture-absorbing disk 21 is disposed on the substrate 22 and includes silica gel and molecular sieve.

[0046] The housing 1 is provided with a first airflow channel and a second airflow channel. The first airflow channel includes a first air inlet 11 and a first air outlet 12. The second airflow channel includes a second air inlet 13 and a second air outlet 14. Both the first airflow channel and the second airflow channel are connected to the moisture absorption tray 21.

[0047] Specifically, the housing 1 of the waterless humidifier of this application is made of environmentally friendly and durable ABS plastic, which is sturdy and not easily deformed. The housing 1 is cleverly installed inside the air conditioner near the evaporator, so that the heat generated by the evaporator can be used to assist the dehumidification of the moisture absorption plate 21 without affecting the normal operation of other components of the air conditioner. The substrate 22 is made of high-strength ceramic material, providing stable support for the moisture absorption plate 21 and ensuring its stability during air conditioner operation. The moisture absorption plate 21 is tightly attached to the substrate 22 and is composed of silica gel and molecular sieves. Its unique material formula gives it excellent moisture absorption and dehumidification performance. Silica gel can quickly absorb a large amount of moisture at low temperatures, while molecular sieves can efficiently release moisture at high temperatures. During the moisture absorption stage, the low-temperature outside air introduced by the first airflow channel enables the moisture absorption plate 21 to fully absorb moisture; during the humidification stage, the warm indoor air introduced by the second airflow channel causes the moisture absorption plate 21 to quickly dehumidify, releasing the stored moisture into the room.

[0048] This device can be used in air conditioners. In one specific embodiment, the first air inlet 11 of the first airflow channel is located on the outer casing of the air conditioner near the outdoor side, and the first air outlet 12 leads to the outside. During dehumidification, cold outside air enters through the first air inlet 11, absorbs moisture through the desiccant 21, and is discharged from the first air outlet 12. The second air inlet 13 of the second airflow channel communicates with the indoor air. Inside the air conditioner, near the cross-flow fan blades, the second air outlet 14 is located on the side closest to the room, and its angle is optimized to ensure that the humidified air can be evenly diffused to all corners of the room. During humidification, warm indoor air enters through the second air inlet 13, is dehumidified by the desiccant 21, and the moisture-laden air is blown out from the second air outlet 14, thus humidifying the room. This waterless humidification device automatically absorbs moisture from the outside air through the desiccant 21 and releases it into the room when needed, completely avoiding the hassle of manually adding water. Users no longer need to worry about the humidifier running out of water and causing humidification interruption, greatly improving the user experience. For example, during indoor heating in winter, users do not need to get up frequently to add water to the humidifier and can enjoy a comfortable humidified environment continuously.

[0049] In addition, the device is connected to an air source at a specific temperature through a first airflow channel and a second airflow channel, with a clear division of labor. This design allows the moisture absorption and dehumidification processes to proceed in an orderly manner, enhancing the stability of the waterless humidifier's operation.

[0050] Example 2

[0051] like Figure 1 As shown, this embodiment is an improvement on embodiment 1.

[0052] In this embodiment, the first airflow channel is used to communicate with a low-temperature air source, and the second airflow channel is used to communicate with a high-temperature air source; a filter screen 3 is provided at the first air inlet 11 and / or the second air inlet 13.

[0053] Filter 3 effectively filters the air entering the airflow channel. In one usage scenario, filter 3 at the first air inlet 11 intercepts dust, pollen, impurities, etc., from the outside air, preventing them from entering the moisture absorption tray 21, avoiding clogging the pore structure of the moisture absorption tray 21, ensuring that the moisture absorption tray 21 always maintains good moisture absorption and dehumidification performance, and extending its service life. Filter 3 at the second air inlet 13 filters dust from the indoor circulating air, ensuring cleaner air after humidification, improving indoor air quality, reducing respiratory problems caused by inhaling dust, and protecting user health.

[0054] Specifically, filter 3 is made of a material with high filtration efficiency and good durability. Common materials include polypropylene (PP) fibers, which are chemically resistant, lightweight, and have high filtration efficiency, effectively intercepting dust, pollen, impurities, and other pollutants in the air. The finely interwoven fibers of this material form numerous tiny pores, making it difficult for small-particle pollutants to pass through, ensuring that the air entering the device is effectively purified.

[0055] Example 3

[0056] like Figures 1-5 As shown, this embodiment is an improvement on embodiment 1.

[0057] In this embodiment, a heating device 4 is provided at the second air inlet 13. Specifically, the heating device 4 of this application can be a ceramic PTC heating element. The ceramic PTC heating element is made by mixing and firing ceramic and conductive materials, and has advantages such as constant temperature heating, safety and reliability, and rapid heating. Internally, it consists of multiple tightly arranged PTC thermistor sheets. When current passes through, these sheets heat up rapidly, converting electrical energy into heat energy. Furthermore, as the temperature rises, its resistance increases, and the current decreases, thereby automatically adjusting the heat output to achieve constant temperature control and avoid safety issues caused by overheating.

[0058] The heating device 4 can increase the temperature of the air entering the second airflow channel. Because the molecular sieve in the moisture-absorbing plate 21 has high-temperature dehumidification properties, the heated air allows the moisture-absorbing plate 21 to release the stored moisture more quickly and completely. In winter, when indoor heating is needed, the ambient temperature is relatively low, and relying solely on room-temperature air flowing through the moisture-absorbing plate 21 for dehumidification may not be efficient. However, by increasing the air temperature through the heating device 4, the dehumidification speed of the moisture-absorbing plate 21 can be significantly accelerated, increasing the humidification capacity and allowing the indoor humidity to reach a suitable level more quickly. This meets people's needs for rapid indoor humidity adjustment and improves user comfort during use.

[0059] In addition, the heating device 4 can flexibly control the temperature of the air entering the moisture absorption tray 21 by adjusting its power or temperature setting. When the indoor humidity is low and a rapid increase in humidity is needed, the power of the heating device 4 can be appropriately increased to raise the air temperature, thereby increasing the dehumidification capacity of the moisture absorption tray 21 and enhancing the humidification effect. When the indoor humidity is close to the suitable range, the power of the heating device 4 can be reduced to decrease the dehumidification capacity of the moisture absorption tray 21 and prevent the indoor humidity from becoming too high. This flexible adjustment method can better adapt to different indoor environments and user needs, achieving precise control of indoor humidity.

[0060] Example 4

[0061] like Figure 1 As shown, this embodiment is an improvement on embodiment 1.

[0062] In this embodiment, a plurality of weight sensors 221 are provided at the bottom of the substrate 22.

[0063] Specifically, the weight sensor 221 of this application is used to detect changes in the weight of the moisture absorption tray 21. This weight sensor 221 can be a pressure strain gauge type weight sensor 221. This type of weight sensor 221 features high accuracy and fast response, enabling it to accurately measure changes in the weight of the moisture absorption tray 21 in real time.

[0064] In this embodiment, the weight sensor 221 can directly measure the weight change of the moisture absorption tray 21, accurately obtaining the amount of moisture absorbed or released by the moisture absorption tray 21 through real-time monitoring. Since the weight of the moisture absorption tray 21 increases during moisture absorption and decreases during dehumidification, the weight sensor 221 can convert these weight changes into electrical signals and transmit them to the air conditioner's control system. Based on the weight data, the control system can more accurately determine the working status of the moisture absorption tray 21, such as whether the moisture absorption tray 21 has reached its maximum moisture absorption capacity or whether the dehumidification process is complete. Based on the precise data provided by the weight sensor 221, the humidity control logic of the air conditioner can be further optimized. The control system can more intelligently control the opening and closing time and operating duration of the air inlets and outlets of the first and second airflow channels based on the real-time weight of the moisture absorption tray 21.

[0065] Example 5

[0066] like Figures 1-5 As shown, this embodiment provides a heat pump air conditioner, which includes the waterless humidification device described above.

[0067] Specifically, the air conditioner includes a main body 100, within which a fresh air device 5 is provided. The fresh air device 5 has a first airflow channel and a second airflow channel, and a waterless humidification device is disposed within the fresh air device 5. The main body 100 also includes a heat exchanger for exchanging heat with the indoor environment.

[0068] Specifically, the fresh air unit 5 is equipped with a high-powered fan, enabling efficient air exchange. Outdoor air enters through the fresh air inlet and is first filtered through multiple layers of filters 3, including a pre-filter 3 to filter large particles of dust and pollen, a medium-efficiency filter 3 to capture fine dust and some microorganisms, and an activated carbon filter 3 to adsorb harmful gases and odors. The filtered fresh air enters the interior of the fresh air unit 5 and, under the action of the fan, is delivered indoors through a specific air duct. The air duct of the fresh air unit 5 in this application may differ from the first and second airflow channels of the waterless humidifier.

[0069] In this embodiment, the waterless humidifier is integrated into the fresh air unit 5, which is located within the heat pump air conditioner main body 100. This highly integrated design effectively saves space. Furthermore, the integrated design reduces the number of connecting parts between devices, lowering the probability of malfunctions and improving overall stability and reliability. The combination of the humidifier and the fresh air unit 5 not only regulates indoor humidity but also improves indoor air quality. In winter, it solves the problem of indoor dryness while ensuring indoor air freshness, creating a more comfortable and healthy indoor environment for users.

[0070] Example 6

[0071] like Figures 1-5 As shown, this embodiment is an improvement on embodiment 1.

[0072] In this embodiment, a guide vane 7 and a first driving device are provided at the second air outlet 14. The guide vane 7 is rotatably disposed at the second air outlet 14, and the first driving device is used to drive the guide vane 7 to rotate. Specifically, the first driving device can be a motor, which drives the guide vane 7 to rotate to change the air outlet direction.

[0073] The air guide plate 7 can rotate under the action of the first drive device, flexibly changing the air outlet direction of the second air outlet 14 to evenly guide the humidified air to every corner of the room. In actual use scenarios, the distribution of people and their usage needs vary in different areas of the room. The rotatable air guide plate 7 can target the delivery of humidified air to the areas where it is needed. For example, in the living room, where people's activity areas are relatively dispersed, adjusting the angle of the air guide plate 7 can ensure that all locations, such as the sofa area and dining area, receive appropriate humidity, avoiding situations where the humidity is too high or too low in some areas, effectively improving the uniformity of the overall indoor humidity and optimizing the user experience.

[0074] In addition, properly adjusting the angle of the air guide plate 7 helps improve the efficiency of the waterless humidification function of the heat pump air conditioner. By precisely guiding the humidifying airflow, excessive air accumulation in local areas or the creation of humidification dead zones are avoided, allowing the moisture released by the moisture absorption plate 21 to be more effectively diffused into the indoor space, reducing energy waste and improving humidification efficiency.

[0075] More preferably, in this embodiment, both the first air inlet 11 and the second air inlet 13 are provided with an adjustment mechanism 6. The adjustment mechanism 6 includes a baffle 61 and a second driving device 62. The baffle 61 is rotatably disposed at the air inlet, and the second driving device 62 is fixed outside the air inlet, and the second driving device 62 drives the baffle 61 to rotate. Specifically, the structure of the baffle 61 is adapted to the structure of the air inlet so that the baffle 61 can adjust the size of the air inlet.

[0076] In this embodiment, the second driving device 62 drives the baffle 61 to rotate, which can precisely adjust the opening size of the air inlet, thereby precisely controlling the airflow entering the first and second airflow channels. During the dehumidification stage, when the outside air humidity is high, the opening of the baffle 61 of the first air inlet 11 can be appropriately reduced to reduce the amount of air entering, preventing the moisture absorption plate 21 from absorbing too much moisture and affecting the subsequent dehumidification effect. During the humidification stage, the opening of the baffle 61 of the second air inlet 13 is adjusted according to the indoor humidity requirements and the dehumidification capacity of the moisture absorption plate 21 to control the flow of warm indoor air entering, so that the dehumidification speed of the moisture absorption plate 21 matches the indoor humidification requirements, achieving precise regulation of indoor humidity.

[0077] Different usage environments and operating conditions require different airflow rates at the air inlet. In cold winter regions, where outdoor air temperatures are very low, the intake air volume can be reduced by adjusting the first air inlet 11 baffle 61 to prevent excessive cold air from entering and affecting the indoor temperature. In humid summer regions, the opening of the first air inlet 11 baffle 61 can be appropriately enlarged to improve moisture absorption efficiency. Similarly, in situations where there are many people indoors and humidity demands vary significantly, the second air inlet 13 baffle 61 can be flexibly adjusted to meet real-time humidification needs. This adaptability allows waterless humidification devices and heat pump air conditioners to operate stably and efficiently under various complex operating conditions and environments.

[0078] Furthermore, a humidity sensor 110 is provided at the bottom of the main body 100.

[0079] In this embodiment, the main body 100 is provided with a controller, which is electrically connected to the humidity sensor 110 and the second driving device 62.

[0080] A humidity sensor 110 is installed at the bottom of the main body 100 to effectively obtain relatively accurate indoor humidity information. The bottom area typically has relatively stable airflow and is less affected by local airflow or temperature changes. The humidity sensor 110 can stably monitor the overall indoor humidity, avoiding measurement errors caused by airflow disturbances and providing a reliable data basis for subsequent humidity adjustment. The controller is electrically connected to the humidity sensor 110 and the second drive device 62, forming an intelligent control system. The humidity sensor 110 transmits the real-time monitored indoor humidity data to the controller, which analyzes and judges based on preset humidity thresholds. When the indoor humidity is lower than the set lower limit, the controller sends a command to the second drive device 62 to drive the baffles 61 at the first air inlet 11 and the second air inlet 13 to adjust the size of the air inlets. For example, reducing the opening of the baffle 61 at the first air inlet 11 reduces the entry of dry outside air; increasing the opening of the baffle 61 at the second air inlet 13 allows more indoor air to flow through the dehumidification plate 21 for dehumidification and humidification, thereby increasing the indoor humidity. Conversely, when the indoor humidity is higher than the set upper limit, the controller controls the second drive device 62 to perform the opposite operation to keep the indoor humidity within a comfortable range, thus achieving automatic and precise adjustment of indoor humidity.

[0081] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0082] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0083] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
