Description

Multi-directional air blower

The invention relates to a hand dryer device, in particular to a multi-directional air outlet hand dryer device.

As people's demands for quality of life are higher, many hygiene details in daily life are increasingly valued, and the most obvious targets in life can be seen from public bathroom equipment. Since many of the first public sanitary fixtures have to be touched by the user, they have been improved to use the sensor to detect the user's use state to operate automatically; the original user may cause the hand after washing the hand. The water dripped everywhere and progressed to a paper towel with a special hand. However, due to the environmental awareness of the extraction of paper towels, the tree resources have been taken seriously, making the dryers a trend, and slowly replacing the paper towels.

Nowadays, there are many styles of hand dryers. The principle of drying hands is mainly to use the motor to rotate the blades to suck in air, heat the air, and send out hot air to achieve the purpose of drying the palm. In the current existing technologies, as shown in the patent cases of the Republic of China No. M357271 and No. 579813, the commonality of the two patents is that the dryer has an air outlet outside and exhausts the air at the air outlet to dry. The user's hand, but the two patents only have a single air outlet, and the air direction is a one-way air outlet, the user can not quickly dry when operating, and the range of the air outlet area of the dryer Too small, resulting in limited airflow, requires a lot of power to dry the hands completely.

In addition, U.S. Patent No. 7,555,209 and U.S. Patent No. 7,576,162, and the patents of WO-A No. WO 2007/020699 disclose a design different from the conventional conventional hand dryer. The design has a hand insertion portion, and a plurality of air outlets are respectively arranged on the front and rear sides of the hand insertion portion to form a front and rear two-way air outlet. In addition to allowing the palm and the back of the hand to be simultaneously dried by the wind, the user is also enlarged. The range of hands heated.

The aforementioned patents mainly increase the range of the hand-drying area by increasing the number of air outlets and the form of two-way air knife airflows before and after, thereby saving the time required for drying hands, although the design can effectively improve the traditional single and one-way out The problem of air drying the mobile phone, but the airflow generated by the two-way airflow is still limited, and only the two sides of the user's hand can be blown. The user must repeatedly move the hands up and down in the dryer to receive the forward and backward winds, even though the palms and hands are dried, but the gaps on the hands, such as fingers and nails, are still wet.

The main object of the present invention is to overcome the problem that conventional hand dryers can only be unidirectional or forward and backward, and cannot be completely dried and require a long drying time.

To achieve the above object, the present invention provides a multi-directional air outlet drying device comprising a high-pressure airflow generating device for generating a high-pressure airflow and a casing. The housing includes a first opening for insertion of a user's hand and a hand drying space communicating with the first opening. The hand-drying space includes a first wall surface and a second wall surface facing the first wall surface, and at least one third wall surface facing the hand-drying space is disposed between the first wall surface and the second wall surface. The first wall surface and the second wall surface are at least one first air outlet, and the third wall mask has a second air outlet. The first and second air outlets are connected to the high-pressure airflow generating device to discharge the high-pressure airflow, and the high-pressure airflow emitted by the first air outlet nozzle and the high-pressure airflow emitted by the second air outlet nozzle have respectively a first output airflow axis and a second output airflow axis. The first output airflow axis and the second output airflow axis intersect in the hand dryer space. The angle between the first output airflow axis and the second output airflow axis is greater than or less than or equal to 90°.

The multi-directional air-drying device of the present invention is applicable to the structure, the first wall surface, the second wall surface and the third wall surface are connected to each other to be enclosed around the hand-drying space, or the first wall surface, the second wall surface or the third wall surface There is an open mouth connected to the hand drying space. The third wall surface has a first turning angle or a second turning angle between the first wall surface and the second wall surface. The first wall surface, the second wall surface or the third wall surface may have a curved surface or a planar structure as required by the design.

The multi-directional air drying hand-drying device of the invention can be applied to a horizontal extension type dryer or a vertical extension type dryer. In the form of a horizontally extending type of hand dryer, the hand opening has a second opening for the user's hand to extend in a direction relative to the first opening.

The multi-directional air-drying device of the invention not only has a traditional one-way or two-way air supply mode, but also increases the high-pressure airflow in other directions that the user receives during the drying process, and provides a plurality of different directions of airflow. The palm can accept high-pressure airflow from multiple directions, so that each part can be dried at the same time. The user can achieve the complete drying effect in a short time without repeatedly moving the palm of the hand.
