Description

Ring-shaped dryer

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

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, as shown in the patents of US Pat. No. 7,555,209 and WO 2007/020699, the two patents differ from the aforementioned patents in that the two patents have a plurality of air outlets, and It is arranged on the corresponding sides of the hand drying area to form a two-way air outlet, which not only enlarges the range of the hand drying area, but also allows the palm and the back of the hand to be subjected to the wind at the same time when drying the hand through the structure of the two-way air outlet. .

The US 7555209 and WO 2007/020699 patents increase the range of the hand dryer area by increasing the number of air outlets and the form of the two-way air knife outlet, thereby saving the time required for drying hands, although the traditional single and one-way can be greatly improved. The problem of drying the mobile phone, but still a little inconvenient to use, because the air flow generated by the two-way air can only blow the corresponding two sides of the user's hand, can not provide a more comprehensive airflow, the hands need to be from bottom to top Slowly pumping and drying, the hand thus dried the palm and the back of the hand, but the gaps on the hands, such as the fingers, nails, etc. are still wet, so if you need to completely dry your hands, you must continue Slowly move up and down.

The main object of the present invention is to improve the problem that the conventional dryer has insufficient airflow direction and cannot achieve rapid drying.

In order to achieve the above object, the present invention provides a ring-shaped air-drying mobile phone, which includes a casing and a gas supply device, and the casing is provided with an connecting portion and an air outlet portion connecting the connecting portion, The air outlet portion has two extending portions extending from the connecting portion and a connecting portion connecting the two extending portions to form an annular hand-drying passage, and the air outlet portion is provided with a plurality of nozzles corresponding to the drying hand passage, and a first opening and a second opening are respectively disposed at two ends of the drying hand passage; and the gas supply device is disposed in the connecting portion, and is provided with an air guiding duct to guide the gas to the air outlet portion, and The nozzles eject gas toward the hand dryer passage to form an annular outlet.

In a specific embodiment of the present invention, the housing has a front half shell and a rear half shell connected to the front half shell, and the first opening and the second opening are respectively located in the front half shell and the rear half shell, and the connection The thickness of the portion is greater than the thickness of the air outlet portion, and the connecting portion and the air outlet portion form a drop portion in the rear half shell. The gas supply device has a wind drum to connect the air duct, the air duct has two first guiding portions respectively disposed on the two extending sections, and is extended by the first guiding portion And a second guiding portion of the connecting portion, wherein the nozzles are coupled to the air guiding tube, and are inclined by the first opening toward the second opening, so that the gas is obliquely ejected.

The detailed description and technical content of the present invention will now be described as follows:

Referring to FIG. 1 and FIG. 2, the present invention is a ring-shaped air blow dryer. The hand dryer mainly includes a casing 10 and a gas supply device 20 disposed inside the casing 10. The body 10 includes a front half shell 11 and a rear half shell 14 assembled to the front half shell 11 . The front half shell 11 has a side frame 12 and a panel 13 , and the side frame 12 side is connected to the rear half shell 14 . The other side is provided with an assembly opening 121 for arranging the panel 13. The housing 10 is provided with a connecting portion 15 and an air outlet portion 16 connected to the connecting portion 15. The thickness of the connecting portion 15 is The venting portion 16 and the venting portion 16 form a drop portion 17 in the rear half shell 14; and the vent portion 16 has two extending portions extending from the connecting portion 15 161, and a connecting section 162 connecting the two extending sections 161, the connecting section 162, the two extending sections 161 and the connecting portion 15 form an annular hand dryer channel 18, and at both ends of the hand dryer channel 18, That is, the panel 13 of the front half shell 11 and the rear half shell 14 are respectively provided with a first An opening 131 and a second opening 141. In addition, the housing 10 is provided with an infrared sensor 19 on the connecting portion 162 of the air outlet portion 16 , and an air inlet 122 is disposed below the side frame 12 .

The gas supply device 20 of the hand dryer is disposed in the connecting portion 15 and mainly includes a wind drum 21 and a wind guiding pipe 22 connected to the wind drum 21. The wind drum 21 is connected with a flow guiding member. 25, and the flow guiding member 25 has a guiding groove 251 and a fixing portion 252 at the air inlet 122. The fixing portion 252 is in communication with the guiding groove 251 and a heating device 26 is fixed. The wind drum 21 is further connected with a circuit board 27 for controlling the timing of starting the air drum 21. When the air drum 21 is activated, external air is introduced into the heating device 26 from the air inlet 122, and is heated and heated. The guide groove 251 is introduced into the wind drum 21. In addition, as shown in FIG. 3, the air duct 22 has two first guiding portions 23 respectively disposed in the two extending portions 161, and a first guiding portion 23 extending into the connecting portion 162. Two guiding portions 24, and the first guiding portion 23 and the second guiding portion 24 respectively have a plurality of first nozzles 231 and a plurality of second nozzles 241 that pass through the outlet portion 16 and correspond to the drying path 18 The wind drum 21 transmits the gas to the extension portion 161 and the connecting portion 162 of the air outlet portion 16 through the first guiding portion 23 and the second guiding portion 24 of the air guiding duct 22, and the first portion The nozzle 231 and the second nozzles 241 eject gas toward the hand dryer channel 18 to form an annular air outlet, which constitutes the main structure of the present invention.
