Abstract
Description
- The present invention relates to a hand drying apparatus and particularly to a multidirectional air discharge hand drying apparatus.
- With people's increasing demand on life quality hygiene also becomes an important issue on people's mind in their daily life, this is especially notable on public lavatory facilities. In the past many public lavatory facilities must be operated manually by users. Continuous progresses have been made these years, for instance sensors have been deployed to detect user's use conditions to make automatic operation possible. Now dedicated paper towels have been provided in many sites to enable users to dry hands after washing without dripping water everywhere. However, with increasing awareness of environmental protection and reservation, tree is seen as a precious resource not to be wasted lightly. As a result, using hand dryers to replace paper towel gradually becomes trendy.
- At present there are myriad types of hand dryers on the market. Hand drying mainly adopts a principle of using spinning vanes driven by a motor to suck in air, then the air is heated and ejected to dry user's hands. For instance, R.O.C. patent Nos.
M357271 and579813 disclose a hand dryer that has an air outlet on the exterior to eject air to dry user's hands. They have only one air outlet to eject the air in one direction, hence cannot dry user's hands quickly. Moreover, the covering range of the air outlet is too small and air discharge volume is limited, hence a greater amount of electric power has to be consumed to fully dry the hands. -
U.S. patents Nos. 7,555,209 ,7,657,162 andWO patent 2007/020699 also disclose hand dryers that adopt a different design. They have a hand insertion portion and multiple air outlets at the front and rear sides of the hand insertion portion to form dual-direction air ejection to drive user's palm and backside of hands at the same time. Such a design greatly increases hand drying scope. - While the aforesaid techniques increase hand drying scope by increasing the air outlets and providing dual-direction air ejection to save hand drying time, and offer some improvement over the conventional hand dryer of single outlet and one-direction air ejection, the dual-direction air ejection can blow merely two opposite sides of user's hands but not in an all-around fashion. User's have to move two hands up and down during drying, and even if the palm and backside of the hands have been dried, hand crevices, such as finger gaps and finger nails could still remain wet.
- The primary object of the present invention is to solve the problem of the conventional hand dryers that provide merely one way or front and rear air ejection and cannot fully dry user's hands and take longer duration to do drying.
- To achieve the foregoing object the invention provides a multidirectional air discharge hand drying apparatus which includes a high-pressure airflow generation device and a casing. The casing has a first opening to receive insertion of user's hands and a hand drying compartment leading to the first opening. The hand drying compartment includes a first wall surface and a second wall surface facing the first wall surface, and at least one third wall surface interposed between the first and second wall surfaces and faced the hand drying compartment. The first and second wall surfaces have at least one first air discharge nozzle. The third wall surface has a second air discharge nozzle. The first and second air discharge nozzles are connected to the high-pressure airflow generation device to eject high-pressure airflows. The high-pressure airflows ejected from the first and second air discharge nozzles have respectively a first output airflow axis and a second output airflow axis that cross in the hand drying compartment. The first output airflow axis and second output airflow axis form an included angle greater or smaller than, or equal to 90 degrees.
- The multidirectional air discharge hand drying apparatus of the invention can adopt various structures, such as the first, second and third wall surfaces can be connected to each other in a closed manner to surround the hand drying compartment, or form a slot on one of them leading to the hand drying compartment. The third wall surface may also form a first angle with the first wall surface or a second angle with the second wall surface. The first, second or third wall surface may also be formed in an arched surface or a flat surface according to design requirements.
- The multidirectional air discharge hand drying apparatus of the invention is adaptable to horizontal or vertical insertion hand dryers. When adopted on the horizontal insertion hand dryers a second opening is provided in the hand drying compartment opposing the first opening to allow user's hands to be extended outwards.
- The multidirectional air discharge hand drying apparatus of the invention, in addition to providing one way or front and rear air discharge as the conventional techniques do, further provides high-pressure airflow in other directions to dry user's hands. By providing air discharge in multiple and different directions user's palms can receive the high-pressure airflow in multiple directions so that every portion of the hands can be dried at the same time without being moved constantly, and user's hands can be fully dried in a short time period.
- The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

It has a circularhand drying compartment 11 with thefirst wall surface 111a andsecond wall surface 112a orthird wall surface 113a formed respectively in an arched surface and connected to each other to form a closed annular structure. The first output airflow axis a of thefirst wall surface 111a and the second output airflow axis b of thethird wall surface 113a form an included angle θ2 greater and smaller than, or equal to 90 degrees depending on the selected locations of the first and secondair discharge nozzles - The multidirectional air discharge hand drying apparatus of the invention can also adopt various structures.
FIGS. 1 ,2 and3 show the first, second and third wall surfaces 111, 112 and 113 connected to each other in a closed annular manner to surround thehand drying compartment 11. However, this is not the limitation of the invention.FIGS. 4 and5 show other applicable embodiments in which aslot first wall surface second wall surface third wall surface hand drying compartment 11 to become an annular structure with a notch formed thereon. - As a conclusion, the multidirectional air discharge hand drying apparatus of the invention has first air discharge nozzles formed on the opposing first and second wall surfaces and also a second air discharge nozzle on the third wall surface facing the hand drying compartment. Hence when user's hands are placed in the hand dryer the palms and backside of the hands can receive high pressure airflow, and other portions and crevices of the hands also can receive the high pressure airflow blowing sideward. As a result, airflow receiving area increases and multidirectional drying effect can be accomplished. Drying efficiency increases and drying quality also improves. It provides a significant improvement over the conventional techniques.
