Abstract

PROBLEM TO BE SOLVED: To dry hands by sending out moisture relatively to a finger tip direction at the time of pulling out the hands from an insertion port by jetting an air flow tilted to the finger tip direction from plural air jetting holes provided so as to be a sharp angle to the insertion port. SOLUTION: When the hands are inserted to the insertion port 7, a switch is automatically turned on and a motor-driven blower 6 starts an operation. The air flow generated by the rotation of the motor-driven blower 6 is passed through an air flow route 8 and jetted from the plural air jetting holes 9 to the insertion port 7 at a high speed. At this time, the insertion port 7 is turned to the angle of about 45 deg. from a horizontal direction and the wet hand is inserted at the angle of about 45 deg.. Also, the air jetting holes 9 are provided at the sharp angle to the insertion port 7. Thus, the high-speed air flow jetted from the air jetting holes 9 extremely smoothly flows along the surface of the hands. That is, the high-speed air flow jetted from the air jetting holes 9 acts so as to smoothly separate the moisture from the surfaces of the hands.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet and a toilet
The present invention relates to a hand drying apparatus used in a kitchen or the like, which is used to dry hands after washing hands with water.

[0002]

2. Description of the Related Art A conventional hand dryer has a structure as shown in FIG. In this, the air blown by the electric blower 1 is heated by the heater 2 and the hand is dried by the warm air discharged from the blower port 3, and it replaces the operation of wiping the hand with a towel or a handkerchief. At this time, the user rubs a wet hand so that the warm air is blown to the wet hand to dry the hand quickly.

[0003]

SUMMARY OF THE INVENTION The conventional hand dryer having the above-mentioned structure requires a considerable amount of time to dry a wet hand, which makes it inconvenient to use. In other words, the time required for drying is longer than the time required for wiping with a handkerchief and exceeds the limit that can be tolerated. The reason for this is that, for example, the capacity of the power supply is limited and the amount of air blown and the heater capacity cannot be increased so much, and the efficiency of heat transfer from the heater to the air is extremely poor.

SUMMARY OF THE INVENTION The present invention solves the problems of the conventional structure as described above, and an object thereof is to provide a hand dryer which can dry hands in a short time.

[0005]

The first means of the present invention for achieving the above object is to incline toward a fingertip from a plurality of air ejection holes provided at an acute angle with respect to an insertion opening. When the hand is pulled out from the insertion port, the moisture is relatively sent out toward the fingertip to dry the hand.

The second means of the present invention is a hand dryer for vibrating the air ejection holes in a direction substantially at right angles to efficiently separate the water entangled in the fingers.

A third means of the present invention is to vibrate an air ejection hole provided at an acute angle with respect to an insertion opening in a direction substantially at a right angle to spray a complicated jet on the surface of the hand to dry the hand quickly. It is a hand dryer that can be used.

In the fourth means of the present invention, a sensor is used to distinguish between the palm and the finger, and the air ejection hole is vibrated only at the finger portion so that it does not vibrate on the palm, so that the drying time can be further shortened. It is used as a drying device.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) Hereinafter, an embodiment of the present invention will be described. FIG. 1 is a cross-sectional view showing the configuration of the hand dryer of this embodiment. An electric blower 6 that blows indoor air is provided on the upper portion of the main body 5. In addition, a part of the main body 5 has an insertion opening 7 for inserting a hand at an angle of about 45 ° with respect to the horizontal direction.
Is provided. The air flow blown by the electric blower 6 is blown out at high speed through the air flow path 8 and the air blowout hole 9 provided in the insertion port 7. Air ejection hole 9
Is provided so that the angle α is an acute angle with respect to the insertion opening 7 as shown in FIG. The end of the insertion slot 7
It is the drain port 7a.

The operation of this embodiment will be described below.
When a hand is inserted into the insertion opening 7, a switch (not shown) is automatically turned on and the electric blower 6 starts operating. The airflow generated by the rotation of the electric blower 6 is jetted through the airflow path 8 from the plurality of air jet holes 9 to the insertion port 7 at high speed. At this time, the insertion opening 7 is at an angle of about 45 ° with respect to the horizontal direction, and a wet hand is inserted at an angle of about 45 °. Further, the air ejection hole 9 is provided at an acute angle α with respect to the insertion port 7 as shown in FIG.
Therefore, the high-speed air flow ejected from the air ejection hole 9
It flows extremely smoothly along the surface of the hand.
That is, the high-speed airflow ejected from the air ejection holes 9 acts so as to smoothly separate the water from the surface of the hand. Therefore, the water is relatively sent in the fingertip direction as the hand is pulled out from the insertion opening.
The water thus separated from the hand is discharged to the outside of the machine through the drain port 7a.

As described above, according to this embodiment, it is possible to dry the hand in a short time.

(Second Embodiment) Next, a second embodiment of the present invention will be described. FIG. 3 is a cross-sectional view showing the configuration of the hand dryer of this embodiment. The air ejection hole 10 of the present embodiment is set at an angle of approximately 90 ° with respect to the insertion port 7, and vibrates in the left-right direction as shown in FIG. That is, the insertion opening 7 is vibrated by a motor and a cam mechanism (not shown). Further, this vibration is set to have a steady or unsteady time interval.

The operation of this embodiment will be described below.
The airflow generated by the blower 6 passes through the airflow path 8 and is jetted at high speed from the air jet holes 10. At this time, since the air ejection holes 10 vibrate in the left-right direction, this high-speed air flow behaves so as to vibrate in a direction substantially perpendicular to the insertion direction of the hand. As a result, the surface of the hand is swept by the high-speed airflow not only in the direction from the wrist to the fingertip but also in the direction perpendicular to the finger. Therefore, the water is separated from the surface of the hand without any gap.

As described above, according to the present embodiment, since the air ejection holes 10 are vibrated in the left and right directions, it is possible to dry the hands in a shorter time.

At this time, if the air ejection holes 12 are provided as shown in FIG. 5, the hands can be dried more effectively in a short time. That is, the air ejection holes 12 are set to form an acute angle α with respect to the insertion port 7. Therefore, the high-speed airflow ejected from the air ejection holes 9 collides with the hand in an oblique direction while vibrating in the left-right direction. That is, the water adhering to the hand collides with the hand in the direction of sending the water toward the fingertip. As a result, the surface of the hand is swept not only in the direction from the wrist to the tip of the finger but also in the direction perpendicular to the finger by a high-speed airflow, and moisture is separated from the surface of the hand without leaving any gap, so that the hand can be dried in a shorter time. Is something that can be done.

(Third Embodiment) Next, a third embodiment of the present invention will be described. FIG. 6 is a cross-sectional view showing the configuration of the hand dryer of this embodiment. Reference numeral 12 denotes the air ejection hole described in the second embodiment, which is set so as to form an acute angle α with respect to the insertion port 7 and vibrates in the left-right direction. Reference numeral 14 is a sensor that detects the palm and the fingertip separately, and in the present embodiment, it is composed of an ultrasonic oscillating element and an ultrasonic receiving element. The sensor 14 may be composed of a light emitting element and a light receiving element.

The operation of this embodiment will be described below.
The sensor 14 can detect the palm and the fingertip separately. In the present embodiment, the air ejection hole 12 is stationary while the sensor 14 is detecting the palm, and the air ejection hole 12 is vibrated in the left-right direction while detecting the fingertip. That is, by vibrating the air ejection holes 12 at the fingertip portion and making the air ejection hole 12 stand still at the palm portion, the attached water can be more effectively separated from the hand.

As described above, according to the present embodiment, it is possible to realize the hand dryer which can dry the hand in a shorter time.
