Abstract

PURPOSE:To prevent a decreasing of volume of atomization and an blowing interruption phenomenon so as to realize a regular superior humidifying operation by a method wherein a first hole is made at an outer circumference of a bottom part of an atomization cylinder and a second hole through which the water column generated under a vibration of supersonic wave vibrator is formed at the central part of the atomization cylinder. CONSTITUTION:A water column 6 is provided with a hole 7b at a central part of a bottom part 7a of an atomization cylinder 7 which is mounted on the supersonic waver vibrator 5 in view of a formation of the supersonic wave vibrator, a hole 7c is provided at an outer circumference of the atomization cylinder, thereby a structure having no hindrance of formation of water column 6. Since the hole 7b has a gradient so as to cause itself to be higher than the bottom part 7a of the circumference thereof, the water droplets are discharged through the hole 7c and are not dripped from the hole 7b. Therefore, the water column 6 is not prohibited from its formation by the dripping water droplets, and is not disturbed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ultrasonic humidifier having an atomizing cylinder above a vibrator.

BACKGROUND OF THE INVENTION Conventionally, this type of ultrasonic humidifier has been constructed as shown in FIGS. 4 and 6. In the figure, an air hole 104 is formed at the tip of an air tube 103 provided in an atomization chamber 102 of a main body 101 of an ultrasonic humidifier, and a shifter 7 is formed through this air hole 104.
It sends out wind from a wind turbine (not shown). Further, a water column 106 generated by imaging with an ultrasonic transducer 105 provided at the bottom of the atomization chamber 102 is atomized in an atomization tube 107 provided at the top of the atomization chamber 107, and this tin is transferred to the fan. The structure was such that the wind from the air was sent into the room through the blow-off nozzle 108. On the other hand, the bottom of the atomizing tube 107 has a bottom 107a to prevent large water droplets in the water column 106 from directly falling onto the water surface and producing a falling sound. The structure was designed to reduce the sound of falling water droplets, as the water droplets are collected on the water surface after falling onto the surface of the water.On the other hand, this bottom part 1o7aK is provided with a hole 1o7b, so that it does not interfere with the formation of the water column 106. was.

Problems to be Solved by the Invention In such a conventional configuration, water droplets that have fallen from the bottom 107a drip downward from both the outer periphery of the bottom 107a and the hole 107b. Since the water droplets dripping from the extra-large 107b side fall onto the ultrasonic vibrator 10B, they may prevent or disturb the formation of the water column 108, resulting in a decrease in the amount of atomization or the discharge of mist from the blow-off nozzle 108. There is a problem in that a so-called "breathing phenomenon" occurs in which the state appears to stop momentarily.

The present invention is intended to solve these problems, and aims to realize regular and good humidification by preventing a decrease in the amount of atomization and the phenomenon of breathlessness.

Means for Solving the Problem In order to solve this problem, the present invention includes a tube at the bottom and a bottomed cylindrical atomization tube provided above the ultrasonic vibrator. A first hole is provided on the outer periphery of the bottom of the tube, and a second hole is provided in the center through which the water column generated by the vibration of the ultrasonic vibrator passes, and the hole is provided at a higher position than the bottom. It is composed of

Function: With this configuration, the hole at the bottom of the atomizing tube is provided at a higher position than the bottom, so that the water accumulated at the bottom of the atomizing tube always drips from the first hole on the outer periphery of the bottom, and the water column Since the water does not fall onto the vibrator through the second hole through which it passes, the formation of a water column is no longer hindered.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2.

In the figure, the inside of a box-shaped main body 1 is provided with an atomization chamber 2 having an atomization tube 7 provided below from the top surface and a wind tube 3 provided above from the bottom surface.

An air hole 4 is provided in the upper part of the air cylinder 3, and air from a fan (not shown) is sent into the viscosifying chamber 2. Reference numeral 5 indicates an ultrasonic transducer that atomizes water provided at the bottom of the atomization chamber 2, θ indicates a water column generated by the vibration of the ultrasonic transducer 5, and the water column 6 is placed on the ultrasonic transducer. The formation of the water column 6 is obstructed by providing a hole 7b in the center of the bottom 7a of the atomizing tube 7 and a hole 7C in the outer periphery, which is installed on the ultrasonic vibrator 6 to form a water column. It has a unique structure. Most of the mist atomized in the atomizer tube 7 is carried by the wind sent out from the air hole 4 at the top of the atomizer tube 3 when it passes through the atomizer tube 7, and is sent into the room from the blow-off nozzle 8. It will be done.

Here, large-sized mist and water droplets adhering to the inner wall of the atomizing tube 7 and blow-off nozzle 8 fall onto the bottom 7a of the atomizing tube 7 and do not fall directly onto the water surface, reducing the sound of water droplets falling. Moreover, since the hole 7b is sloped as shown in FIG. 2 so as to be higher than the surrounding bottom 7a, water droplets are discharged from the hole 7C and do not drip from the hole 7b, so that the water column e is not prevented from forming or disturbed by falling water droplets.

This prevents a decrease in the amount of atomization and the occurrence of a suffocation phenomenon.

Note that FIG. 3 shows another embodiment of the present invention, in which the hole 7b
Instead of increasing the position of the hole 7b by making the surrounding bottom 7a slope higher, a convex portion 7d is provided on the bottom 7a of the atomizing tube 7 so that the hole 7b is made higher than the surrounding bottom 7a. This is what I did.

It should be noted that the present invention is not limited to the above-mentioned embodiments.
It goes without saying that it is only necessary to make the hole 7b higher than the surrounding bottom part a so that water droplets do not drip from the hole 7b.

Effects of the Invention As described above, according to the present invention, the hole through which the water column passes through the bottom of the atomizing cylinder is provided at a higher position than the surrounding bottom, thereby preventing water droplets from falling from the hole. It does not prevent or disturb the formation. Therefore, it is possible to prevent a decrease in the amount of atomization and the occurrence of a breath phenomenon, thereby achieving the effect of realizing regular and good humidification.
