[0002] Currently, air conditioners are widely used in daily life due to their cooling and heating functions. However, as users' demands for diversified air conditioner functions increase, the single cooling and heating function of air conditioners can no longer meet users' needs, resulting in a poor user experience.

[0003] Among the related technologies, there is an air conditioning system including an indoor humidification device and an indoor unit. The indoor humidification device includes a water collection tank and a humidifier. The water collection tank is located below the indoor unit and collects the condensate from the evaporator of the indoor unit through a water collection pipe. The humidifier includes an ultrasonic atomizer placed at the bottom of the water collection tank, a fan placed at the top of the water collection tank, and an exhaust pipe connecting the fan outlet to the indoor unit.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: Indoor humidifiers take up too much indoor space, making the installation of air conditioning systems more difficult and costly.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0028] Combination Figure 1-6 As shown, in some embodiments, the humidifying air conditioner includes: a housing 100, an atomizing module 200, and an atomizing nozzle 300. A water tank 110 is provided inside the housing 100; the atomizing module 200 is disposed within the water tank 110; the atomizing nozzle 300 is connected to the air outlet of the atomizing module 200 and is disposed at the return air inlet 120 of the housing 100, extending along the length of the return air inlet 120.

[0029] The humidifying air conditioner provided in this embodiment uses a water tank 110 inside the housing 100 to store humidifying water. The atomizing module 200 is housed within the water tank 110 to reduce its space requirements. An atomizing nozzle 300 connects to the air outlet of the atomizing module 200. The water mist generated by the atomizing module 200 is sprayed along the atomizing nozzle 300 to the return air vent 120, where it enters the housing 100 with the return airflow and is then blown out into the indoor environment to complete humidification. The placement of the water tank 110 and atomizing module 200 within the housing 100, and the atomizing nozzle 300 at the return air vent 120, reduces the space occupied by the humidifying air conditioner and simplifies its installation. Since the water mist sprayed from the atomizing nozzle 300 enters the housing 100 with the return airflow, a separate airflow module is not required to deliver the water mist, thus reducing humidification costs.

[0030] Optionally, the return air vent 120 is provided on the upper side wall of the housing 100, and the lower side wall of the housing 100 is provided with an air outlet. The water mist flowing in along the return air vent 120 mixes with the return air flow and is then blown out into the indoor environment through the air outlet to increase the humidity of the indoor environment.

[0031] Optionally, a heat exchanger 130 and a cross-flow fan are provided inside the housing 100, with the heat exchanger 130 positioned between the cross-flow fan and the return air inlet 120. In this way, the negative pressure generated by the cross-flow fan causes the humidifier to draw in return airflow from the return air inlet 120 and then blow it out from the outlet. Since the atomizing nozzle 300 is located at the return air inlet 120, the sprayed water mist flows into the housing 100 under the influence of the return airflow. A single cross-flow fan is sufficient to meet the air supply requirements for humidification and cooling / heating, eliminating the need for a separate fan for humidification air supply. This reduces the humidification cost of the humidifier and makes its overall structure more compact, minimizing space occupation.

[0032] Optionally, the water tank 110 is located at one end of the cross-flow fan along its axial direction. In this way, the water tank 110 makes reasonable use of the space inside the housing 100, making the internal structural arrangement of the housing 100 more compact, further reducing the volume of the housing 100 and reducing the space occupied by the humidifying air conditioner.

[0033] As is understandable, housing 100 refers to the housing 100 of the indoor wall-mounted unit, and will not be described in detail here.

[0034] Optionally, the atomizing nozzle 300 is located above the return air inlet 120. In this way, the water mist sprayed by the atomizing nozzle 300 can fall naturally into the return air inlet 120 under the action of gravity, and flow into the housing 100 better along the return air flow inlet 120.

[0035] Specifically, the atomizing nozzle 300 is located directly above the return air inlet 120.

[0036] Optionally, the return air vent 120 has a rectangular opening structure, and the atomizing nozzle 300 has a long, narrow tubular structure. In this way, the rectangular opening structure of the return air vent 120 can ensure the air intake area of ​​the return air vent 120 while increasing the air intake range of the return air vent 120, and the long, narrow tubular structure of the atomizing nozzle 300 can be adapted to the air intake area of ​​the return air vent 120, so that the sprayed water mist can better enter the housing 100 with the return airflow.

[0037] Optionally, the length of the atomizing nozzle 300 is less than or equal to the length of the return air inlet 120, but greater than or equal to nine-tenths of the length of the return air inlet 120. In this case, if the length of the atomizing nozzle 300 is greater than the length of the return air inlet 120, some of the water mist sprayed from the atomizing nozzle 300 cannot enter the return air inlet 120, and will contaminate the upper sidewall of the housing 100. If the length of the atomizing nozzle 300 is less than nine-tenths of the length of the return air inlet 120, the area of ​​water mist sprayed from the atomizing nozzle 300 is relatively small, making it difficult for the water mist to mix fully with the return airflow, resulting in poor humidification uniformity. Therefore, setting the length of the atomizing nozzle 300 to be less than or equal to the length of the return air inlet 120, but greater than or equal to nine-tenths of the length of the return air inlet 120, ensures that the area of ​​water mist sprayed from the atomizing nozzle 300 is relatively large, improving humidification uniformity, while also preventing the sprayed water mist from falling onto the upper sidewall of the housing 100 and contaminating the housing 100.

[0038] Optionally, the length of the atomizing nozzle 300 is equal to nine-tenths of the length of the return air vent 120. This ensures that the water mist sprayed by the atomizing nozzle 300 covers a relatively large area, improving the uniformity of humidification, while also preventing the sprayed water mist from falling onto the upper side wall of the housing 100 and causing contamination of the housing 100.

[0039] Optionally, the atomizing nozzle 300 is located in the middle of the width direction of the return air inlet 120. In this way, the water mist sprayed by the atomizing nozzle 300 can fall into the middle area of ​​the return air inlet 120, and the water mist can flow more smoothly into the housing 100 along the return air inlet 120, reducing the risk of the upper side wall of the housing 100 being contaminated by water mist.

[0040] It is understandable that the atomizing nozzle 300 being located in the middle position along the width direction of the return air inlet 120 means that the centerline of the atomizing nozzle 300 coincides with the line connecting the midpoints of the two short sides of the return air inlet 120 along the width direction of the return air inlet 120. This will not be elaborated further here.

[0041] Optionally, multiple air outlets 310 are provided on the outer wall of the atomizing nozzle 300, and the multiple air outlets 310 are evenly distributed along the outer wall of the atomizing nozzle 300. In this way, by providing multiple air outlets 310, the water mist in the atomizing nozzle 300 is sprayed out along the multiple evenly distributed air outlets 310, making the water mist sprayed by the atomizing nozzle 300 more uniform, with a wider distribution range, and more evenly entering the return air inlet 120, thereby improving the uniformity of humidification.

[0042] Optionally, multiple air outlets 310 are evenly arranged along the length of the atomizing nozzle 300. Since the atomizing nozzle 300 extends along the length of the return air inlet 120 and has a long, narrow structure, the even arrangement of multiple air outlets 310 along the length of the atomizing nozzle 300 ensures that the sprayed water mist is evenly distributed in the area where the return air inlet 120 is located, allowing the water mist to enter the return air inlet 120 more evenly.

[0043] Optionally, multiple air outlets 310 are provided on the outer walls of the atomizing nozzle 300 on both opposite sides along the horizontal direction. Since the atomizing nozzle 300 is positioned in the middle of the width of the return air inlet 120 and is located above the return air inlet 120, the presence of multiple air outlets 310 on the outer walls of the atomizing nozzle 300 on both opposite sides along the horizontal direction allows the water mist sprayed from the air outlets 310 to flow evenly to both sides of the atomizing nozzle 300 along the horizontal direction. This results in a more uniform distribution of water mist within the air outlet area, and the water mist mixes thoroughly with the return airflow, further improving the uniformity of humidification.

[0044] Optionally, the number of air outlets 310 provided on the opposite outer walls of the atomizing nozzle 300 in the horizontal direction is the same. This makes the amount of water mist sprayed from the opposite areas of the atomizing nozzle 300 in the horizontal direction relatively uniform, thereby making the water mist distribution in the return air inlet 120 area more uniform and further improving the humidification uniformity.

[0045] Optionally, each air outlet 310 has multiple air outlet holes 311. This improves the uniformity of the water mist sprayed from each air outlet 310, allowing the water mist to enter the return air inlet 120 more dispersedly, further improving the uniformity of humidification.

[0046] Optionally, the multiple air outlets 311 of each air outlet 310 are evenly arranged along the length of the atomizing nozzle 300. In this way, the water mist sprayed by the atomizing nozzle 300 through the multiple air outlets 310 has better uniformity.

[0047] Specifically, each vent 310 has three vent holes 311.

[0048] Optionally, the atomizing nozzle 300 is connected to the air outlet of the atomizing module 200 via an exhaust pipe 400. One end of the exhaust pipe 400 extends into the water tank 110 and connects to the air outlet of the atomizing module 200, while the other end extends to the end of the atomizing nozzle 300 and connects to it. In this way, the water mist generated by the atomizing module 200 flows into the atomizing nozzle 300 along the exhaust pipe 400 and is then sprayed out along the atomizing nozzle 300. The arrangement of the exhaust pipe 400 allows for more flexible placement of the atomizing nozzle 300.

[0049] Optionally, the air inlet of the exhaust pipe 400 passes through the water tank 110 and enters the water tank 110, communicating with the air outlet of the atomizing module 200. The air outlet of the exhaust pipe 400 extends through the upper side wall of the housing 100 and communicates with the end of the atomizing nozzle 300. In this way, the water mist generated by the atomizing module 200 flows in along the air inlet of the exhaust pipe 400, flows out along the air outlet of the exhaust pipe 400 into the atomizing nozzle 300, and is then sprayed out along the air outlet 310 of the atomizing nozzle 300.

[0050] For example, the exhaust pipe 400 is divided into three parts: the first part passes through the water tank 110 and is located inside the water tank 110; the second part is located inside the housing 100; and the third part passes through the upper side wall of the housing 100 and extends to the top of the housing 100.

[0051] Optionally, the exhaust end of the exhaust pipe 400 is detachably connected to the end of the atomizing nozzle 300. In this way, the atomizing nozzle 300 can be disassembled when maintenance or cleaning is required, without having to open the housing 100 to disassemble the exhaust pipe 400, thus improving the efficiency of later maintenance and upkeep of the atomizing nozzle 300.

[0052] Optionally, the housing 100 is provided with a water receiving trough 140, and the water tank 110 is connected to the water receiving trough 140 through a water inlet pipe 500. In this way, the condensate collected in the water receiving trough 140 can be introduced into the water tank 110 for humidification, thus reusing the condensate, reducing water waste, and saving energy and protecting the environment.

[0053] Understandably, the water tank 140 is located below the heat exchanger 130 and is used to collect the condensate dripping from the heat exchanger 130.

[0054] Optionally, the inlet end of the water inlet pipe 500 is connected to a first water pump 510, the inlet end of the first water pump 510 is connected to the water receiving tank 140, and the outlet end of the first water pump 510 is connected to both the inlet pipe 500 and the drain pipe 600, with the drain pipe 600 connected to the outdoor environment. In this way, the first water pump 510 provides negative pressure to draw condensate from the water receiving tank 140. When the water tank 110 can completely store the condensate in the water receiving tank 140, the first water pump 510 guides the drawn condensate into the inlet pipe 500, allowing it to flow into the water tank 110 for storage. When the water tank 110 is full, the first water pump 510 guides the drawn condensate into the drain pipe 600 and discharges it into the outdoor environment. This allows the pump to draw condensate from the water receiving tank 140 for humidification and to discharge the condensate from the water receiving tank 140 into the external environment when the water tank 110 is full for humidification.

[0055] For example, the outlet of the first water pump 510 is equipped with a solenoid valve at the position where it connects to the inlet pipe 500 and the drain pipe 600. By controlling the opening and closing of the corresponding solenoid valve, the condensate drawn by the first water pump 510 is controlled to flow into the inlet pipe 500 or the drain pipe 600.

[0056] Optionally, the inlet of the first water pump 510 is connected to the water receiving tank 140 via a suction pipe. In this way, under negative pressure, the water in the water receiving tank 140 is drawn by the suction pipe to the first water pump 510.

[0057] Optionally, a germicidal lamp is installed inside the water tank 110. In this way, the germicidal lamp can irradiate and sterilize the internal environment of the water tank 110, reducing the risk of bacterial growth in the humidifying water and ensuring the cleanliness of the humidifying water.

[0058] Optionally, a filter module 520 is connected to the water inlet pipe 500. In this way, the filter module 520 can filter the absorbed condensate water to ensure the cleanliness of the humidifying water flowing into the water tank 110.

[0059] Optionally, the water tank 110 has an overflow pipe 150 on its vertical sidewall, with the overflow pipe 150 connected to the water tank 110 at the upper part of the vertical sidewall. This allows excess humidifying water in the water tank 110 to flow out through the overflow pipe 150, preventing spillage and contamination. The upper position of the overflow pipe 150 also ensures a relatively large storage capacity of humidifying water in the water tank 110, improving its water supply capacity.

[0060] Optionally, the outlet of the overflow pipe 150 is located above the water receiving trough 140. In this way, the humidifying water overflowing from the water tank 110 can flow back into the water receiving trough 140. When the humidifying water in the water tank 110 needs to be replenished, the humidifying water in the water receiving trough 140 can be drawn back into the water tank 110. Alternatively, the overflow water collected in the water receiving trough 140 can be discharged into the outdoor environment through the drain pipe 600, which simplifies the drainage structure of the humidifying air conditioner and reduces costs.

[0061] Optionally, the water inlet of the atomizing module 200 is located at the bottom of the water tank 110. In this way, when the amount of humidifying water in the water tank 110 meets the humidification requirements, the water inlet of the atomizing module 200 can be submerged in the humidifying water in the water tank 110, so as to better absorb the humidifying water in the water tank 110 for atomization and humidification.

[0062] Optionally, the water tank 110 includes a tank body and a tank cover. The upper end of the tank body has an opening, and the tank cover is detachably installed at the opening to close it. In this way, the tank cover can be opened to clean and maintain the inside of the water tank 110, and the tank cover can also be opened to add humidifying water when the condensate is insufficient.

[0063] Specifically, the atomizing module 200 is movably installed inside the housing.

[0064] Specifically, the air intake end of the exhaust pipe 400 passes through the cover and extends into the box body to connect with the atomizing module 200.

[0065] Optionally, the air inlet of the exhaust pipe 400 is detachably connected to the air outlet of the atomizing module 200. In this way, when it is necessary to open the cover to clean the inside of the box, or when the atomizing module 200 malfunctions and needs to be repaired, the cover can be opened to remove the exhaust pipe 400, and then the inside of the box can be cleaned or the atomizing module 200 can be repaired.

[0066] Optionally, the atomizing module 200 is movably disposed within the water tank 110. This allows the atomizing module 200 to be removed from the water tank 110 when the tank cover is opened, facilitating maintenance of the atomizing module 200.

[0067] Optionally, the atomizing module 200 is an ultrasonic atomizing module. In this way, the atomization effect of the ultrasonic atomizing module is relatively better, which can improve the humidification effect.

[0068] For example, since the humidifying water in the water tank 110 is the condensate collected in the water receiving tank 140, the condensate is the water in the indoor air that has changed from a gaseous state to a liquid state. The condensate is pure water and does not contain calcium or magnesium ions. Therefore, there is no risk of calcium or magnesium ion precipitation and pollution in the water tank 110 and the atomizing module 200 during long-term operation. The water mist produced by atomization does not contain calcium or magnesium ions, thus reducing the harm of humidification to the user's health.
