[0035] Please refer to Figure 3 , Figure 3 FIG. 1 is a schematic diagram of the structure of the air outlet module 3 according to an embodiment of the present application. Figures 1 to 3 As shown, an embodiment of the present application provides an air outlet module 3 , which includes a fan 31 , an air collecting box 32 and a plurality of air outlet boxes 33 .

[0036] Among them, the air collecting box 32 is connected to the air outlet of the fan 31, and the air collecting box 32 has a built-in air cavity (not shown in the drawings); each air outlet box 33 has at least one air dispersion port 332 and multiple air inlet ports 331, and the multiple air inlet ports 331 are evenly arranged on the air outlet box 33, and each air inlet port 331 is connected to the air cavity of the air collecting box 32; adjacent surfaces between the multiple air outlet boxes 33 are provided with air dispersion ports 332.

[0037] In one embodiment, two air outlet boxes 33 are provided, and each air outlet box 33 has three air inlets 331. Each air inlet 331 on the air outlet box 33 is connected to the air collecting box 32 through a sub-air duct 35; the fan 31 is connected to the air collecting box 32 through a main air duct 34, and the diameter of the main air duct 34 is larger than the diameter of the sub-air duct 35.

[0038] In one embodiment, the air collecting box 32 has an air collecting structure 321 and a plurality of air dividing structures 322. The air collecting structure 321 is connected to each of the air dividing structures 322 through a single air cavity and / or a plurality of air cavities built into the air collecting box 32. The air collecting structure 321 is disposed on a side wall of one side of the air collecting box 32. There are a plurality of air dividing structures 322, which are also disposed on at least one side wall of the air collecting box 32. The side wall where the air collecting structure 321 is located is adjacent to or opposite to the side wall where the air dividing structure 322 is located. Figure 3 As shown, there are six air distribution structures, and every three air distribution structures are arranged on the side wall of one side of the air collecting box 32. The two side walls provided with the air distribution structures 322 are opposite to each other, and the side walls provided with the air distribution structures 322 are adjacent to the side wall where the air collecting structure 321 is located. In other embodiments of the present application, the side wall where the air collecting structure 321 is located and the side wall where the air distribution structure 322 is located can also be the same side wall.

[0039] In one embodiment, each air inlet 331 on each air outlet box 33 is arranged on an adjacent surface and / or an opposite surface of the air dispersion outlet 332, and the multiple air inlets 331 on each air outlet box 33 are evenly arranged relative to the air dispersion outlet 332, so that the airflow input from the air inlet 331 is evenly output from the air dispersion outlet 332 through the internal chamber of the air outlet box 33.

[0040] In one embodiment, the area of ​​the air outlet 332 on each air outlet box 33 is greater than the total area of ​​the air inlet 331. The air outlet 332 is strip-shaped or rectangular, so that the air outlet area of ​​the air outlet module 3 is enlarged and the air outlet range is widened.

[0041] In one embodiment, the air outlet module 3 further includes at least one sensor 36, which is disposed on the air outlet box 33, and the identification direction of the sensor 36 is consistent with the air outlet direction of the air outlet 332. In one embodiment, there are multiple sensors 36, one sensor 36 is disposed on one air outlet box 33, and the identification areas of each sensor 36 overlap. The sensor 36 is an infrared sensor 36, and other sensors 36 capable of identifying a human body, such as a camera or a laser sensor 36, may also be selected.

[0042] In one embodiment, the air outlet module 3 further includes a heating unit, which is disposed in the air collecting box 32 or each air outlet box 33, and is configured to heat the air to generate hot air. The heating unit can be a device that can convert other energy into heat energy, such as a heating tube and a heat resistance wire.

[0043] like Figures 1 to 3 As shown, in one embodiment, two air outlet boxes 33 are provided, which are respectively installed on the inner walls on both sides of the wash basin 10 and accommodated in the installation cavity 12. Correspondingly, two sensors 36 are also provided, and the two sensors 36 are respectively located between the two air outlet boxes 33 and at the top of the adjacent end. Each air outlet box 33 has three air inlets 331, and the three air inlets 331 are all arranged on the bottom surface of the air outlet box 33. Three sub-air ducts 35 are connected to each side of the air collecting box 32, and the three sub-air ducts 35 on each side correspond to the three air inlets 331 on an air outlet box 33. The air outlets 332 on the two air outlet boxes 33 are opposite to each other, and the air outlet direction is toward the center of the wash basin 10, so as to realize multi-directional air supply and drying for the user's hand drying operation. The user can dry his hands without adjusting the palm posture, avoiding touching the inner wall of the wash basin 10 when adjusting the gesture and needing to wash hands again. In addition, the air outlet box 33 provided on the wash basin 10 can dry the inner wall of the wash basin 10 as much as possible while drying the user's hands, thereby preventing the residual moisture on the inner wall of the wash basin 10 from causing bacteria growth or contamination due to long-term adhesion.

[0044] After the user finishes washing his hands, the sensor 36 detects the infrared signal of the user's hand and generates a corresponding trigger signal. The air outlet module 3 starts working after receiving the trigger signal or responding to the start signal of the trigger signal. In an air outlet process, the fan 31 generates airflow after starting. The airflow output from the air outlet of the fan 31 is transmitted to the air collecting box 32 through the main air duct 34, and is evenly dispersed to each sub-air duct 35 through multiple air outlets on the side wall of the air collecting box 32. The airflow in each sub-air duct 35 is input into the air outlet box 33 through the air inlet 331, and the output is realized in a larger area or a larger range through the air outlet 332 on the air outlet box 33. Multiple air outlet boxes 33 are arranged at multiple positions on the inner wall of the wash basin 10, but the air outlet direction is all toward a fixed area in the wash basin 10, so that the air outlet component can blow air to the user's hands in multiple directions.

[0045] The present application can solve the problems of uneven wind force, single wind direction, inconvenient installation and maintenance in the prior art. The air outlet module 3, hand dryer 2 and wash basin 1 provided in the present application realize the transfer of air flow and the preliminary equal distribution of wind strength after the fan 31 outputs the airflow through the setting of the air collecting box 32, and then realize the uniform introduction of airflow at various positions in the air outlet box 33 and the stable and large-range output of airflow at the air dispersing outlet 332 through the setting and reasonable arrangement of the air inlet 331 and the air dispersing outlet 332 on the air outlet box 33, effectively improving the stability and uniformity of the wind force of the outlet; the present application solves the technical problem that the hand dryer 2 is not conducive to installation, fixing and maintenance because the main unit is too bulky by distributing the wind control components (fan 31 and air collecting box 32) and the air outlet components in the hand dryer 2, and can effectively improve the convenience of installation and maintenance of the hand dryer 2. The present application also realizes multi-directional blowing for the same area or blowing over a larger range, and can also simultaneously realize accelerated evaporation of moisture on the inner wall of the wash basin 10 by setting the position and number of the air outlet boxes 33 in the wash basin 1, and by installing multiple air outlet boxes 33 in multiple positions on the inner wall of the wash basin 10.

[0046] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
