Description

Ring air dryer

technical field

The invention relates to a hand dryer with annular air outlet, in particular to a hand dryer which surrounds a user's hand and generates an annular hand drying airflow.

Background technique

As people have higher requirements for the quality of life, many hygiene details in daily life are paid more and more attention. The most obvious signs in life can be seen from public bathroom equipment. From the very beginning, many public bathroom facilities had to be operated by the user with their own hands, and have been advanced to the use of sensors to detect the user's use status to automatically operate; and the original user may cause hands to be dirty after washing their hands. The water dripped everywhere, until there were special hand-wiping paper towels. However, due to the rising awareness of environmental protection, the use of paper towels has attracted attention to tree resources, making hand dryers a trend and gradually replacing paper towels.

Nowadays, there are many styles of hand dryers, and the main drying principle is nothing more than using 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 palms. In the current existing technology, as shown in patent applications such as Taiwan No. M357271 and No. 579813, the commonality of these two patent applications is that the hand dryer is provided with an air outlet on the outside, and the air is discharged from the air outlet. Dry the user's hands, but these two patent applications only have one air outlet, and the air outlet direction is unidirectional. When the user is operating, he cannot dry quickly, and the air outlet area of the hand dryer The range is too small, resulting in limited air flow, and it takes a lot of power to completely dry your hands.

In addition, US 7555209, WO 2007/020699 and other patent applications are different from the aforementioned patent applications in that the hand dryers disclosed in these two patent applications have multiple air outlets, which are arranged on the corresponding two sides of the hand drying area, forming The form of two-way air outlet not only increases the scope of the hand drying area, but also allows the palm and back of the hand to be exposed to the wind at the same time when drying the hands with the help of the two-way air outlet structure.

US 7555209 and WO 2007/020699 increase the range of the hand drying area by increasing the number of air outlets and the form of two-way air outlets, so as to save the time required for hand drying, although they can greatly improve the traditional single and one-way air outlet. There is a problem with the hand dryer, but it is still inconvenient to use. The reason is that the airflow generated by the two-way air outlet can only caress the corresponding two sides of the user's hands, and cannot provide a more comprehensive airflow. The hands need to be slowly moved from bottom to top to dry. Dry, so even if the palms and backs of the hands are dry, the gaps on the hands, such as between fingers and nails, are still wet, so if you want to completely dry the hands, you must continue to move up and down slowly.

Detailed ways

The detailed description and technical content of the present invention are described below in conjunction with the accompanying drawings:

Please refer to FIG. 1 and FIG. 2 , the present invention is a hand dryer with annular air outlet. The hand dryer mainly includes a housing 10 and a gas supply device 20 disposed inside the housing 10 . The casing 10 includes a front half shell 11 and a rear half shell 14 assembled and combined with the front half shell 11, wherein the front half shell 11 has a side frame 12 and a panel 13, and one side of the side frame 12 is connected to the rear The half-shells 14 are connected to each other, and an assembly opening 121 is provided on the other side for installing the panel 13 .

On the casing 10, there is provided an connecting portion 15 and an air outlet portion 16 connected to the connecting portion 15, wherein the thickness of the connecting portion 15 is greater than the thickness of the air outlet portion 16, and the connecting portion 15 and the air outlet portion 16 form a drop section 17 at the rear half shell 14; and the air outlet portion 16 has two extension sections 161 extending from the connecting section 15, and a connecting section 162 connecting the two extension sections 161 A circular hand drying passage 18 is formed by the connection section 162, the two extension sections 161 and the connecting portion 15, and at both ends of the hand drying passage 18, that is, the panel 13 of the front half shell 11 and the rear half shell 14 are respectively provided with a first opening 131 and a second opening 141 . In addition, the casing 10 is further provided with an infrared sensor 19 on the connecting section 162 of the air outlet 16 , and an air inlet 122 is provided under the side frame 12 .

And the gas supply device 20 of the hand dryer is arranged in the connection part 15, mainly including an air drum 21 and an air guide pipe 22 connected to the air drum 21, wherein the air drum 21 is connected with a flow guide 25 , and the deflector 25 has a deflector 251 and a fixed portion 252 located at the air inlet 122, the fixed portion 252 communicates with the deflector 251 and is fixed with a heating device 26, and the air blower 21 is also connected with a circuit board 27, which is used to control the timing of starting the wind drum 21. When the wind drum 21 is started, the external air is introduced into the heating device 26 through the air inlet 122. Slots 251 are introduced into the wind drum 21 . Please also refer to FIG. 3 , the air duct 22 has two first guides 23 respectively arranged in the two extension sections 161 , and a second guide extending from the first guides 23 into the connecting section 162 . guide part 24, and the first guide part 23 and the second guide part 24 respectively have a plurality of nozzles 231, 241 passing through the air outlet part 16, and the wind drum 21 passes through the first part of the air guide pipe 22. The guide part 23 and the second guide part 24 guide the gas to the extension section 161 and the connection section 162 of the outlet part 16, and the nozzles 231, 241 eject the gas toward the hand drying channel 18 to form an annular outlet. Wind, as such, constitutes the main structure of the invention. In a specific embodiment of the present invention, the nozzles 231 , 241 are inclined from the first opening 131 to the second opening 141 , so that the gas is ejected obliquely.

Please refer to Fig. 4 and Fig. 5 again, since the thickness of the connecting portion 15 is greater than the thickness of the air outlet portion 16, and the connecting portion 15 and the air outlet portion 16 form a drop section at the rear half shell 14 17. Therefore, when the hand dryer is fixed to the wall 30 through the connecting part 15, a gap will be formed between the air outlet part 16 and the wall 30. When the user is drying his hands, his hands can be inserted through the first opening 131 The hand-drying channel 18 protrudes from the second opening 141, thereby obtaining a larger hand-drying range; in addition, since the two extension sections 161 and the connecting section 162 of the air outlet part 16 form an annular air outlet mode, Each position of the hand can be evenly exposed to the wind, so as to achieve the effect of rapid drying; moreover, since these nozzles 231, 241 are inclined from the first opening 131 to the direction of the second opening 141, when drying hands, the hand The moisture on the surface will be sprayed toward the direction of the second opening 141 along the direction of the airflow, and will not be sprayed on the body of the user.

To sum up, the present invention mainly provides an connecting portion 15 and an air outlet portion 16 on the housing 10 of the hand dryer, and the air outlet portion 16 has two extension sections 161 extending from the connecting portion 15 and a connection The connecting section 162 of the two extension sections 161 forms an annular hand-drying channel 18, and a first opening 131 and a second opening 141 are respectively provided at the two ends of the hand-drying channel 18. The air duct 22 guides the gas to the air outlet 16, and ejects the gas toward the hand drying channel 18 to form a circular air outlet, thereby increasing the direction of the air outlet of the hand dryer, so that all parts of the hand can be exposed to the wind and quickly drying.
