[0041] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0043] In the prior art, humidifiers and dehumidifiers are installed in a humidifier and dehumidifier at the same time to meet the user's humidification and dehumidification needs while reducing the equipment's footprint. For example, utility model patent application number 202120782985.3 discloses a humidifier and dehumidifier device that can condense and dehumidify the air through a condenser, or spray humidify the air passing through it through a spray device.

[0044] However, the above-mentioned humidifier-dehumidifier equipped with a spray device may have a dripping problem in its spray device, which may cause water droplets to be blown directly into the room, that is, the water blowing phenomenon, which reduces the user experience.

[0045] like Figures 1 to 5 As shown, the embodiment of the present disclosure provides a humidifier and dehumidifier, which can condense and dehumidify the air flowing through it through the dehumidification device 20, or humidify the water in the water tank 41 through the heating device 30 to humidify the air flowing through it. In this way, the water blowing phenomenon can be avoided and the user experience is improved.

[0046] like Figures 1 to 5As shown, the embodiment of the present disclosure provides a humidifier-dehumidifier comprising: a housing 10, a dehumidifier 20, a water tank 41, and a heating device 30. The housing 10 is provided with a return air port 11 and an air outlet 12; the dehumidifier 20 includes an evaporator 21, which is connected to the return air port 11 and the air outlet 12 via an air duct; the water tank 41 is installed in the housing 10 and is provided with a water storage portion, which is connected to the return air port 11 and the air outlet 12 via an air duct; the heating device 30 is provided in the housing 10 or the water tank 41 and is used to heat the water in the water tank 41; when the dehumidification mode is turned on, the evaporator 21 can condense the air flowing through it to reduce the air humidity; when the humidification mode is turned on, the heating device 30 heats the water in the water tank 41 to increase the air humidity in the air duct.

[0047] Specifically, the humidifier-dehumidifier further includes a fan 50, and the air supply direction of the fan 50 is limited to the air outlet 12. A return air damper is provided at the return air outlet 11, and the return air damper is used to clear or block the return air outlet 11. An outlet damper is provided at the air outlet 12, and the outlet damper is used to clear or block the air outlet 12.

[0048] like Figure 4 As shown, when dehumidification mode is on, the return air damper and the outlet air damper are open. Driven by fan 50, indoor air flows through the return air vent 11 into the air duct of casing 10 and passes through evaporator 21. At this point, evaporator 21 cools the air, lowering its temperature and condensing and dehumidifying it. The dehumidified air flows from the air outlet to outlet 12, where it is blown into the room, reducing indoor humidity.

[0049] like Figure 4 As shown, when humidification mode is on, the return air damper and the outlet air damper are open. Driven by the fan 50, indoor air flows through the return air vent 11 into the air duct and toward the water tank 41. At this time, the heating device 30 heats the water in the water tank 41, accelerating the evaporation of the water therein, thereby humidifying the air passing through the water tank 41. The humidified air flows through the air duct toward the outlet 12, where it is blown into the room, thereby increasing the indoor humidity.

[0050] Such a setting can avoid the water blowing phenomenon and improve the user experience.

[0051] Optionally, the water tank 41 is detachably mounted in the housing 10. Thus, when humidification is required, the user can first remove the water tank 41 from the housing 10 and then add water to the water storage portion. When dehumidification is required, the user can remove the water tank 41 and pour out the water in the water storage portion to avoid affecting the dehumidification effect.

[0052] In some embodiments, the heating device 30 is located between the dehumidification device 20 and the air outlet 12 .

[0053] Specifically, the heating device 30 is fixedly mounted on the housing 10 and is mounted on a side of the dehumidifying device 20 close to the air outlet 12 . In this way, the heating device 30 can heat the air flowing through the evaporator 21 .

[0054] With this configuration, the user can turn on the evaporator 21 alone. The indoor air, after passing through the evaporator 21, becomes low-temperature, low-humidity air and is blown into the room, achieving both dehumidification and cooling. Alternatively, the user can turn on both the evaporator 21 and the heating device 30 simultaneously. The heating device 30 heats the air passing through the evaporator 21, achieving dehumidification while maintaining a constant temperature.

[0055] In practical applications, the temperature of the heating device 30 can be set according to the needs of the user. In this way, the temperature of the air flowing into the room can be controlled while ensuring the dehumidification effect, further improving the user experience.

[0056] like Figure 1 As shown, in some embodiments, the housing 10 is further provided with an air inlet 13, which is connected to the air outlet 12; the humidifier and dehumidifier further includes an air inlet pipe, which is used to connect the air inlet 13 with the outdoor environment.

[0057] Specifically, the air inlet 13 is provided with an air inlet damper, which can clear or block the air inlet 13. When the fresh air mode is on, the fan 50 can drive outdoor air through the air inlet pipe and the air inlet 13 to flow into the humidifier and dehumidifier, and then flow into the room through the air outlet 12 to improve the quality of the indoor air.

[0058] With this arrangement, when the fresh air mode and humidification mode are turned on, the heating device 30 can heat the water in the water tank 41 to heat and humidify the outdoor air flowing through. This arrangement can not only improve the indoor air quality, but also ensure that the air flowing into the room is warm and humid.

[0059] It is understandable that the weather is generally drier in winter, so the demand for humidification function is also greater in winter. The humidification and dehumidification all-in-one machine provided by the above embodiment can simultaneously improve the indoor air quality and humidify the room, further improving the user experience.

[0060] like Figure 5As shown, in some practical applications, the evaporator 21 is arranged at a position corresponding to the air inlet 13 of the casing 10 to cool and dehumidify the air at the air inlet 13. When the fresh air mode and the dehumidification mode are turned on, the fan 50 can drive the outdoor air to flow from the air inlet 13 into the humidifier and dehumidifier, and flow into the room through the air outlet 12. At this time, after the outdoor air flows into the humidifier and dehumidifier through the air inlet 13, the evaporator 21 can cool the inflowing air to achieve condensation dehumidification. The dehumidified outdoor air can be blown into the room through the air outlet 12 to simultaneously improve the indoor air quality and dehumidify the room, further improving the user experience.

[0061] like Figure 1 As shown, in some embodiments, the dehumidification device 20 further includes a condenser 22. The condenser 22 is installed at a position corresponding to the housing 10 and the water tank 41.

[0062] Specifically, the dehumidifying device 20 further includes a compressor 23, and the compressor 23, the condenser 22, and the evaporator 21 are sequentially connected via a circulation pipeline. In this way, water in the circulation pipeline can condense in the condenser 22 to release heat and evaporate in the evaporator 21 to absorb heat.

[0063] The condenser 22 is installed at a position corresponding to the housing 10 and the water tank 41. When the condenser 22 is running, the water in the water tank 41 can be heated by the condenser 22. This arrangement can reduce the power of the heating device 30 to achieve energy saving.

[0064] In some embodiments, the humidifier and dehumidifier further includes a water supply device and a solenoid valve. The water supply device is connected to the water storage portion of the water tank 41 via a pipeline; the solenoid valve is provided in the pipeline and is used to clear or block the pipeline.

[0065] Specifically, the water supply device is used to supply water to the water storage part. When the humidification mode is turned on, the solenoid valve clears the pipeline, and the water supply device can supply water to the water tank 41 through the pipeline. This arrangement allows water to be filled into the water tank 41 without disassembling the water tank 41, making the operation simpler.

[0066] like Figure 3 As shown, in some embodiments, the water delivery device includes: a water pump 42 that can deliver water to the water storage part, or pump water out of the water storage part.

[0067] Specifically, the water pump 42 is located at a position corresponding to the water tank housing 41. In humidification mode, the water pump 42 delivers water to the water tank 41, increasing the efficiency of filling the water tank 41. In dehumidification mode, the water in the water tank 41 can be pumped out by the water pump 42 without removing the water tank 41, making operation more simplified.

[0068] In some embodiments, the heating device 30 is an electric heating element.

[0069] Specifically, the humidifier and dehumidifier is further provided with a power supply device, which is electrically connected to the electric heating element. The power supply device can supply power to the electric heating element so that the electric heating element generates heat.

[0070] Optionally, the heating device 30 is a PTC heating element.

[0071] It can be understood that PTC heating element, also known as PTC heater, is composed of PTC ceramic heating element and aluminum tube. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and energy-saving electric heating element.

[0072] like Figure 1 As shown, in some embodiments, the humidifier and dehumidifier further includes: a control device 61 and a humidity sensor 62. The control device 61 is electrically connected to the dehumidifier 20 and the heating device 30; the humidity sensor 62 is used to obtain the indoor humidity; wherein the humidity sensor 62 is electrically connected to the control device 61 so that the control device 61 controls the dehumidifier 20 or the heating device 30 to turn on or off according to the indoor humidity.

[0073] Specifically, a humidity sensor 62 is mounted on the housing 10 and is used to detect indoor humidity. When the indoor humidity is greater than or equal to a first preset humidity, the dehumidifier 20 is controlled to turn on to dehumidify the room. When the indoor humidity is less than or equal to a second preset humidity, the heater 30 is controlled to turn on to humidify the room.

[0074] In actual applications, the first preset humidity and the second preset humidity can be set according to the actual needs of the user.

[0075] Preferably, the first preset humidity is greater than or equal to 50%. For example, the first preset humidity can be 50%, 60%, or 70%. The second preset humidity is less than or equal to 30%. For example, the second preset humidity can be 30%, 20%, or 10%.

[0076] like Figure 1 As shown, in some embodiments, the humidifier and dehumidifier further includes a temperature sensor 63. The temperature sensor 63 is used to obtain the temperature of the air outlet 12; wherein the temperature sensor 63 is electrically connected to the control device 61, so that the control device 61 controls the dehumidification device 20 or the heating device 30 to be turned on or off according to the temperature in the air duct.

[0077] Specifically, a temperature sensor 63 is installed at a position corresponding to the air outlet 12 in the housing 10 and is used to obtain the temperature of the air outlet 12. When the temperature of the air outlet 12 is less than or equal to a first preset temperature, the heating device 30 is controlled to turn on to heat the air at the air outlet 12. When the temperature of the air outlet 12 is greater than or equal to a second preset temperature, the condenser 22 and the evaporator 21 are controlled to turn on to cool the room.

[0078] In actual applications, the first preset temperature and the second preset temperature can be set according to the actual needs of the user.

[0079] Preferably, the first preset temperature is greater than or equal to 10° C. For example, the first preset temperature may be 10° C., 15° C., or 20° C. The second preset temperature is less than or equal to 40° C. For example, the second preset temperature may be 40° C., 35° C., or 30° C.

[0080] In some embodiments, the humidifier-dehumidifier further includes a water receiving tray, which is disposed below the evaporator 21 and is in communication with the water storage portion of the water tank 41 .

[0081] Specifically, the water receiving pan is fixedly installed below the evaporator 21, and the receiving area of the water receiving pan is greater than or equal to the cross-sectional area of the evaporator 21, so that the condensed water generated by the evaporator 21 can fall completely into the water receiving pan. At the same time, the water receiving pan is installed horizontally above the water tank 41, and the water receiving pan and the water tank 41 are connected by a water pipe, so that the water in the water receiving pan can flow into the water tank 41, thereby achieving the effect of saving water resources.
