Embodiment approach 1

[0028] figure 1 It is a cross-sectional view showing a schematic configuration of the drying device 200 according to the first embodiment. figure 2 Yes figure 1 The perspective view of the appearance of the drying device 200 shown. In addition, in the drawings described below, the Z direction corresponds to the up-down direction.

[0029] [Structure description]

[0030] like figure 1 As shown, the drying device 200 of Embodiment 1 has: a main body 1, which is formed with a hand insertion part 2 for finger insertion; an air flow generating part 6, which is arranged in the main body 1; a hand detection sensor 30, which detects whether the finger is inserted into the hand insertion part 2 ; and a control device 31 that drives the air flow generating part 6 based on the detection result of the hand detection sensor 30 .

[0032] The main body 1 has: a hand insertion part 2 formed in a concave shape for inserting a finger at the upper part; a nozzle part 4...

Embodiment approach 2

[0097] Figure 7 It is a front view of part of the nozzle hole 5D of the nozzle of the drying apparatus of this Embodiment 2. The front view shape of the nozzle hole 5D is wavy. That is, in Embodiment 1, the case where the shape of the nozzle hole 5 is a straight slit shape has been described, but in this Embodiment 2, the shape of the opening viewed from the outlet side of the nozzle hole 5D is wave-like. The situation will be explained. In addition, in this Embodiment 2, the same code|symbol is attached|subjected to the part common to Embodiment 1, and it demonstrates centering on a difference.

[0098] like Figure 7 As shown in (a), the nozzle hole 5D is a wavy (substantially sinusoidal) slit having a plurality of peaks and valleys in the left-right direction. And, if Figure 7 as shown in (b) Figure 7 As shown in the enlarged view of part A of (a), the valley portion of the nozzle hole 5D is composed of an upper end outer contour 60a and a lower end outer contour 6...

[0113] Figure 9 It is a longitudinal cross-sectional view of the drying device 203 according to the third embodiment. like Figure 9 As shown, the main body 101 forming the outer contour has a hand insertion opening 102 on the front, and is provided with a hand insertion portion 103 as a processing space connected to the hand insertion opening 102, so that the hand can be inserted and taken out.

[0114] The hand insertion part 103 is formed as an open groove-shaped concave part with the front and both sides open on the front lower part of the main body 101, and the water receiving part 104 and the inner side forming the lower part are provided with a curved surface structure standing part at its end edge. The barrier structure 105 is formed to prevent water from flying sideways and forwards. The bottom of the water receiving part 104 is inclined downward toward the front, and a drain port 106 is provided at the inclined lower end.

Abstract

　The purpose of the present invention is to provide a drying device that can reduce noise while suppressing decreases in drying performance. The drying device is provided with a body in which a concave hand insertion part is formed, an airflow-generating part provided inside the body, and a nozzle part formed in the hand insertion part of the body, the nozzle part having a nozzle hole through which air fed in from the airflow-generating part is blown out; the nozzle part has an inflow surface extending along the direction in which the nozzle hole is formed, and an uneven part provided so as to protrude from the inflow surface, the top surface of the uneven part having a flat surface formed so as to extend from the side of the inflow surface to an outlet of the nozzle hole.

Description

technical field [0001] The invention relates to a drying device. Background technique [0002] Compared with paper towels and rental towels, a drying device that dries wet hands by using the airflow jetted from the nozzle holes has the following characteristics: low operating cost, hygienic because it can be used without contact, and excellent maintenance-saving properties. [0003] However, the drying device ejects air flow generated by a fan or the like from an air outlet (equivalent to a nozzle hole described below), and when the air flow is increased in speed to improve drying performance, there is a problem of increased noise. [0004] In addition, as a drying device that solves the above-mentioned problems, for example, Patent Document 1 discloses a drying device having a discharge port in which steps connected to each other in the flow direction of the air flow are formed on the inner side of the wall surface forming the discharge port. shaped bumps. [0005] prior ...
