Description

Hand dryer with protective cover {HAND DRYER INCLUDING PROTECTIVE COVER}

The present invention relates to a hand dryer, and more particularly, to a hand dryer including a protective cover.

In general, a hand dryer is a device that is disposed in a toilet in a public place to forcibly remove water from hands wet with human water. Since the hand dryer uses ambient air, it can give a person a sense of cleanliness that can be received from a bathroom in a home. In addition, since the hand dryer does not use a conventional paper towel, it reduces resource waste and does not cause a problem of disposal.

However, since the hand dryer has a shape in which human hands can be inserted and uses the flow of ambient air, the hand dryer can transfer water from the hands of the person toward the face or clothes while being driven. The hand dryer is described in detail in Korean Patent Publication No. 10-2004-0076572 (2004.09.01). The bite delivered to the face or clothing may require additional action from the person. The additional action may correspond to cleaning of the face or clothing.

Through this, the hand dryer may give a discomfort to a person by transferring water to a person's face or clothes. The discomfort may lead to the use of paper towels instead of hand dryers or natural drying after the washing of the hands of the person. The paper towels cause environmental problems for waste paper disposal, and the natural drying may require a long time consumption of a person to drain water from the hands of a person.

In order to solve the above conventional problems, the problem to be solved by the present invention is to provide a hand dryer suitable for preventing the movement of water from the hands wet to the face or clothes while driving.

Embodiments according to the present invention provide a hand dryer comprising a connecting body, an upper body, a protective cover, and a lower body. The connecting body consists of a first rectangular plate. The upper body is located along the upper end of the connecting body while having a shape of cutting one quarter of a short area perpendicular to the longitudinal direction of the circular column, and extends the curved surface in the shape away from the connecting body. The protective cover engages with the upper body and rotates about the curved surface. The lower body is composed of a second rectangular plate and protrudes from the lower end of the connecting body to face the upper body.

The upper body includes first rotating shafts and a step motor coupled to each other therein. The first axes of rotation extend from both sides of the step motor toward both sides of the upper body.

The protective cover includes second rotating shafts and a protective plate. The second rotational shafts are located outside the upper body and are rotatably coupled with the first rotational shafts through the both sides of the upper body, respectively, and are rotated along the both sides of the upper body via the step motor. Do it. The protective plate is coupled with the second rotational shafts and moves along the curved surface in response to the rotational movement of the second rotational shafts.

The protective cover includes second rotating shafts and a protective plate. The upper body has rotating guide holes passing through the edges facing each other on the curved surface. The second rotation shafts are positioned in the rotation guide holes to be rotatably coupled with the first rotation shafts, respectively, and to rotate along the rotation guide holes through the step motor. The protective plate is coupled with the second rotational shafts and moves along the curved surface in response to the rotational movement of the second rotational shafts.

One of the connecting body, the upper body and the lower body includes a controller. The controller supplies an input pulse to the step motor. The step motor is configured to rotate the protection plate at an angle through the first rotational axes and the second rotational axes.

One of the connecting body, the upper body and the lower body includes a contactless sensor. The contactless sensor is configured to sense hands of a person approaching between the upper body and the lower body to supply an electrical signal to the controller.

As described above, the hand dryer according to the present invention includes a step motor inside and a protection cover outside to surround the wet hands of the person with the protection cover through the rotation of the protection cover corresponding to the driving of the step motor. It is possible to prevent the movement of water from the hands of the person toward the face or clothes.

The heating and blowing member 57 includes a heater and a blowing fan which are sequentially positioned along the flow of air therein.

The heating and blowing member 57 may be electrically connected to the controller 28. The heater is configured to receive an electrical signal from the controller 28 to heat the air in the blowing guide member 55. Subsequently, the blower fan is supplied with an electrical signal from the controller 28 to force the heated air to the nozzle 59. However, the heating and blowing member 57 may include a blowing fan and a heater which are sequentially positioned along the flow of air therein.

The upper body 30 may further include a step motor 44 and the first rotation shaft 48. The step motor 44 and the first rotation shaft 48 are disposed below the blowing guide member 55, but are not limited thereto.

The step motor 44 is electrically connected to the controller 28.

The step motor 44 is configured to receive the pulse signal from the controller 28 to rotate the first rotating shafts 48 at a predetermined angle. That is, the step motor 44 may control the rotational movement of the first rotating shafts 48 in response to the pulse signal of the controller 28. The first rotational shafts 48 extend from both sides of the step motor 44 toward both sides of the upper body 30. The first rotation shafts 48 may penetrate the upper body 30.

On the other hand, the protective cover 60 is disposed on the upper body 30. The protective cover 60 is configured to rotate with respect to the curved surface S1 of the upper body 30 in combination with the upper body 30. To this end, the protective cover 60 includes a protective plate 63 and the second rotation shaft (66). The protective plate 63 is located on the curved surface (S1) of the upper body 30 has a 'T' shape formed at right angles to the longitudinal direction of the nozzle 59 of the blowing guide member 55, but is not limited thereto. It doesn't work.

The second rotation shafts 66 are disposed outside the upper body 30. The second rotation shafts 66 are respectively connected to both sides of the 'T' shape at the upper portion of the 'T' shape of the protective plate 63 through one end thereof. The second rotation shafts 66 may extend from both sides of the protective plate 63 toward both sides of the upper body 30. The second rotation shafts 66 may have coupling portions 69 at the other ends, respectively.

In this case, the second rotation shafts 66A may rotate along both sides of the upper body 30. The first rotation shafts 48 and the second rotation shafts 66 may move the protection plate 63 along the curved surface S1 of the upper body 30. The protective plate 63 is in contact with the lower body 10, but is not limited thereto. In addition, the controller 28 transmits an electrical signal to the heating and the blowing member 57 in the blowing guide member 55. The heating and blowing member 57 may heat the cold air 74 introduced into the tuyeres 51 by using a heater and a blowing fan, and discharge the heated air 78 toward the nozzle 59. .

In this case, the heated air 78 may be discharged from the nozzle 59 at a constant speed relative to the cold air 74 through a change in the air delivery pressure of the blower fan and the opening area of the blower induction member 55. . The heated air 78 may remove moisture from hands wet with water. The protective cover 60 may prevent the transfer of water from the human hand toward the face or clothes by using the protective plate 63.
