The present application claims priority to Chinese patent application No. 202111683444.6, filed on Dec. 31, 2021, and entitled “HUMIDIFYING APPARATUS”.
This application relates to the technical field of household appliances, specifically, to a humidifying apparatus.
As people's demands become higher and higher, evaporative-type humidifying apparatuses without white powder are increasingly accepted by the market. Among the evaporative-type humidifying apparatuses in the market, most have immersive-type wet curtains and water-pump-based spray-type wet curtains. The immersive-type wet curtains tend to become moldy and smelly during use, thus resulting in poor user experience. Considering this problem, designers tend to design water-pump-based spray-type wet curtains. When the water-pump-based spray-type wet curtain is arranged above a water surface, a water passage needs to be constructed between the water and the wet curtain. The existing water passage mostly includes two independent and unconnected water channels: a water supply channel and a drainage channel. During a process of manufacture, the water supply channel and the drainage channel need to be processed separately. On the one hand, the assembly efficiency is low, and on the other hand, the tooling cost is high.
Therefore, the technical problem to be solved by this application is to overcome the deficiency of low assembly efficiency of the humidifying apparatus in the prior art, and a humidifying apparatus that can improve the assembly efficiency is provided.
In order to solve the above technical problems, this application provides a humidifying apparatus, including a water tank, a water pump, a wet curtain assembly, and a water passage structure. The water tank has a water storage chamber. A water inlet of the water pump is adapted to communicate with the water storage chamber. The wet curtain assembly is disposed above the water storage chamber and has a water supply port and a drainage port. The water passage structure is an integrated structure and includes a water inlet channel and a return water channel spaced apart from each other. An upper end of the water inlet channel is connected to the water supply port, and an upper end of the return water channel is connected to the drainage port. A lower end of the water inlet channel is connected to a water outlet of the water pump, and a lower end of the return water channel is in communication with an inside of the water storage chamber.
Further, the return water channel includes a water directing surface, and from top to bottom, the water directing surface is configured to incline in a direction approaching the water inlet channel.
Further, a bottom of the wet curtain assembly is provided with a downwardly recessed water collecting tank, the drainage port is arranged in a side wall of the water collecting tank, and a top end of the water directing surface is configured to extend to a side opposite to the drainage port.
Further, a bottom end of the return water channel is configured to extend to a bottom of the water storage chamber.
Further, the water pump is disposed below the water tank; the water tank has a drain outlet; and the water inlet of the water pump is in communication with the drain outlet of the water tank.

Further, a first assembly annular groove is formed on an outer side of the lower end of the water inlet channel, and the first sealing ring is arranged inside the first assembly annular groove.
Further, the wet curtain assembly includes a bottom cover, a wet curtain, and a net cover. The water supply port and the drainage port are both arranged in the bottom cover. The wet curtain is arranged on the bottom cover. The net cover is fixedly connected to the bottom cover and surrounds the wet curtain. The net cover is provided with a liquid distributor located on a top of the wet curtain. A water supply channel is arranged inside the net cover, and a top end of the water supply channel is in communication with the liquid distributor. A top end of the water inlet channel is configured to pass through the water supply port and to be sealingly connected to a bottom end of the water supply channel through a second sealing ring.
Further, a second assembly annular groove is formed on an outer side of the top end of the water inlet channel, and the second sealing ring is arranged inside the second assembly annular groove.
Further, the wet curtain, the bottom cover, and the net cover are arranged inside the water tank and located above the water storage chamber; the wet curtain assembly further includes a bracket for the wet curtain; and the bracket for the wet curtain is fixedly connected to the net cover and supported on a top of the water tank.
Further, the bracket for the wet curtain has a through hole corresponding to a center of the wet curtain; the bracket for the wet curtain is provided with a water guiding surface surrounding the through hole; and the water guiding surface is configured to guide water to flow to the bottom cover.
In the humidifying apparatus provided by this application, the upper end of the water inlet channel is connected to the water supply port of the wet curtain assembly, and the lower end of the water inlet channel is connected to the water outlet of the water pump, which can pump the water in the water tank to the wet curtain assembly and supply water for the wet curtain assembly. When air passes through the wet curtain assembly, the humidity of the air increases. The water flowing down from the wet curtain assembly can flow back into the water storage chamber through the drainage port and the return water channel, so that the water can be recycled. By integrating the water inlet channel and the return water channel into an integrated structure, the assembly efficiency can be improved and the tooling costs can be saved.

As people's demands become higher and higher, evaporative-type humidifying apparatuses without white powder are increasingly accepted by the market. Among the evaporative-type humidifying apparatuses in the market, most have immersive-type wet curtains and water-pump-based spray-type wet curtains. The immersive-type wet curtains tend to become moldy and smelly during use, thus resulting in poor user experience. Considering this problem, designers tend to design water-pump-based spray-type wet curtains. When the water-pump-based spray-type wet curtain is arranged above a water surface, a water passage needs to be constructed between the water and the wet curtain. The existing water passage mostly includes two independent and unconnected water channels: a water supply channel and a drainage channel. During a process of manufacture, the water supply channel and the drainage channel need to be processed separately. On the one hand, the assembly efficiency is low, and on the other hand, the tooling cost is high.
In view of this, this embodiment provides a humidifying apparatus having a high assembly efficiency.
