Description

The present invention relates to a cold air conditioner.

Generally, when two or more kinds of fluids are mixed or, for example, various powders and chemicals added to the fluid are uniformly dispersed, a step of injecting chemicals and the like and a step of stirring are used except for an automation machine. Are often separate steps. Further, in the injection step, tools and devices for injecting are used, and in the stirring step, tools and devices for stirring are used.
If stirring is not performed, mixing after injection will utilize convection due to the temperature difference and concentration of each fluid, etc., or expect diffusion of substances, in which case it will take a lot of time. It has become.
Then, in the case of mixing reactive substances or heating by steam injection or the like, it is desired to quickly perform stirring.

Conventionally, for example, a device for stirring a liquid in a container that uniformly mixes the liquid in the container is known (see Patent Document 1).
The in-container liquid agitator disclosed in Patent Document 1 agitates a liquid such as printing ink or petrochemical contained in a container so that a mixture such as a solvent becomes uniform.

Japanese Unexamined Patent Publication No. 11-147032

However, the in-container liquid agitator disclosed in Patent Document 1 has the following problems.
That is, the liquid stirring device in the container is configured to drive and rotate an air motor on a rotating shaft having a stirring blade attached to the tip. The stirring blades are normally downward, and when rotating, they are opened in the direction orthogonal to the rotation axis by centrifugal force. The air motor is supported by a clamp, and the clamp is mounted on a telescopic mount. Has been done. Therefore, the number of parts is large and the structure is complicated.
Moreover, since the stirring blade is formed in the shape of a thin blade and the rotating shaft is long, there is a risk of unexpected injury if not handled carefully.
Further, in the in-container liquid agitator disclosed in Patent Document 1, only the in-container liquid is agitated, and the fluid for agitating is not injected.

By the way, in a general evaporation type cold air blower, a drum having a large surface surface like a honeycomb core is immersed in water to wet the surface and blown on it, or a cloth or non-woven fabric having a high water supply rate is immersed in water to wind. The temperature of the water is lowered by the heat of vaporization of the water, and the heat of the air is taken away to lower the air to near the wet-bulb temperature.
If the scale is small, the ratio of surface area to volume is large and design is easy, but as the scale is increased, the ratio of surface area to volume becomes relatively small, so there is a limit to the increase in size. In addition, since substances dissolved in water remain on the evaporated surface, it is necessary to regularly clean or replace the evaporated surface.

[Purpose of Invention]
An object of the present invention has been proposed to solve each of the above problems, and it is possible to maintain a constant water droplet density per space even if the size of the room is increased and the volume of the room is increased. A blower-type cold air blower that randomly discharges small-diameter water droplets into the case body to obtain contact with air and evaporate to remove heat of vaporization so that the problem of surface area-volume ratio is not restricted. To provide .

In order to achieve the above object, the cold air conditioner according to the present invention is made of a flexible material, has a tube portion at the tip for ejecting a fluid toward a space, and undergoes forward wave motion by self-excited vibration. It is a cold air conditioner equipped with a flexible nozzle.
With the case body
A water tank disposed at the bottom of the case body and containing the fluid, and
It is provided vertically inside the case body, and the lower end is arranged so as to form a gap space with the upper surface of the water tank, and the inside of the case body is partitioned into a first chamber and a second chamber. Board and
A nozzle holder arranged in the first chamber and holding the flexible nozzle,
While being disposed below the case body, and a fluid supply means for supplying to said flexible nozzle the fluid is via the nozzle retaining bearing member from the water tank,
A blower provided on the upper part of the side wall of the first chamber to blow an outside wind into the first chamber and bring the wind into contact with the fluid to cool the air by the fluid.
It is arranged in the upper part of the second chamber, and the cooled air in the first chamber is drawn into the second chamber from the first chamber via the gap space, and the indoor air is discharged to the outside. It is characterized by being equipped with a ventilation duct.

According to the cold air blower of the present invention, the density of water droplets per space can be kept constant even if the volume is increased and the volume of the room is increased. Since the surface area is the sum of the surfaces of water droplets, the surface area changes by the square. On the other hand, the problem of the surface area to volume ratio that the volume (volume) changes by the cube does not occur.
In addition, the evaporation surface is the surface of water droplets, and by selecting the particle size of the water droplets, it may evaporate completely due to the wind of the blower, or it may get out of the case body by the wind, or it may emit wet wind. It can also be avoided that it ends up.
Further, unlike the conventional method, a complicated mechanism such as a mechanism for driving or replacing a drum type evaporator is not required.
Also, if the upper part of the case body is made of a transparent material, you can enjoy watching the nozzles sprinkle water droplets like rain.

〔overall structure〕
Hereinafter, an embodiment of the cold air conditioner according to the present invention will be described with reference to FIGS. 1 to 3.
FIG. 1 is an overall view showing the cold air conditioner 80 , FIG. 2 is a front view showing a flexible nozzle, and FIG. 3 is a perspective view showing a flexible nozzle.

Of the present embodimentThe cold air conditioner 80It is configured by using a flexible nozzle (hereinafter, simply referred to as a nozzle) 10.
That is,Of the present embodimentIn the cold air conditioner 80, the nozzle 10Inside the case body 81 ToWater droplets are randomly discharged, and the water droplets are blown by a blower.Sent into the case body 81Sky The heat of vaporization is removed from the air by contacting it with qi.It is an application of the principle of.

[Explanation of nozzle]
First, the nozzle 10 will be described.
The nozzle 10 is an application of the nozzle disclosed in "Japanese Patent Application No. 2013-238060" filed by the present applicant, and is disclosed in "Patent No. 4711112" filed by the applicant and registered as a patent. A nozzle having substantially the same shape as the nozzle and having a function of causing self-excited vibration is used.

That is, the nozzle 10 self-excited and vibrates by the reaction force generated when water or air is ejected from the nozzle 10 to induce a bending motion, and this bending motion is called a forward wave motion and is almost the same as the caudal fin of a fish. Since it is the same movement, it produces propulsive force or stirring force. Then, it is formed of a flexible material such as silicon rubber and has a flexible tube portion 10d at the tip portion so that water such as a lake or a pond can be agitated by the bending motion.
Further, via 2 and 3, the fluid supply unit (not shown) and nozzle 10 are connected by a fluid hose (not shown) via a pipe fitting 11, the fluid hose to so that the water or air at a predetermined pressure to put al nozzle 10 above the fluid supply instrumentation is fed.

The nozzle 10 will be described in more detail.
As shown in FIGS. 2 and 3, the nozzle 10 includes a nozzle body portion 10a, a base end portion of the nozzle body portion 10a, that is, a thin tube insertion portion 10b integrally formed on the fluid supply side, and the nozzle body portion. It is formed by having a guide fin portion 10c integrally formed on the tip end side of the guide fin portion 10a and a small-diameter flexible tube portion 10d integrally formed on the tip end of the guide fin portion 10c.

The flexible tube portion 10d used has an inner diameter of, for example, 1 mm and an outer diameter of, for example, 2 mm.
Therefore, self-excited vibration of the nozzle 10, particularly the flexible tube portion 10d, is possible even with water or air sent by weak water pressure or air pressure. As a result, an energy saving effect can be expected.

Further, the inner diameters of the thin tube portion 11a and the flexible tube portion 10d are in the range of 1 mm to 2 mm, but are not limited to these dimensions and have an appropriate diameter so as to facilitate the generation of convection. Can be adopted.
On the other hand, the pipe joint 11 is provided with a thin tube portion 11a, and by inserting the thin tube portion 11a into the thin tube insertion portion 10b of the nozzle 10, the fluid hose via the nozzle mounting hose 18 or the like. The 42 and the nozzle 10 are connected to each other.

Here, self-excited vibration and forward wave motion will be briefly described.
First, self-excited vibration will be described.
There are at least three actions of the self-excited vibration nozzle on the fluid.

The first is the injection action. This is an action of injecting water or air (second fluid) pumped from the ejection port 10d of the nozzle 10 into water (first fluid) such as a pond. This injection action is It has nothing to do with self-excited vibration.

The second is the spraying action. This is because the nozzle 10 vibrates by self-excitation and the position and direction of the ejection port 10d are constantly changing, so that the injection position of the second fluid that has been pumped with respect to the first fluid in the environment is always changed. It is to be changed and injected. In this spraying action, since there are many injection points in spatial coordinates, injection can be performed randomly. And this spraying action is related to self-excited vibration.

The third is the stirring action. This is because the nozzle 10 continues self-excited vibration, which can be called progressive wave motion, so that it has the action of stirring with respect to the first fluid of the environment and transports the first fluid of the environment due to the progressive wave motion. It is an action of causing a flow and directly stirring the first fluid. And this stirring action is also related to self-excited vibration.
These three actions are performed at the same time, and are characterized in that they do not occur alone and that all of them stop when the injection is stopped.

Next, the forward wave motion will be described.
The forward wave motion is a wave motion in which the bending point is directed from the base end portion of the nozzle 10 to the nozzle tip portion, and the first fluid in the environment generally surrounded by the bending point is carried by the wave motion to flow the flow. Birth.
Then, this flow causes friction at the contact point between the action of carrying the first fluid in the new environment to the injection point of the nozzle 10 and the fluid in which the flow itself does not generate the flow, and the first fluid is agitated in this part as well. It is carried out. That is, since the volume of stirring is large, mixing of the first fluid and the second fluid in the vicinity of the nozzle 10 is promoted. Therefore, strictly speaking, the nozzle 10 agitates the first fluid (water such as a pond) and the mixed fluid of the first fluid and the second fluid (water or air).
Further, the flow due to the forward wave motion becomes a power source for promoting convection with respect to the first fluid, and has a greater force for promoting a large flow than the case where only the wake caused by the jet flow of the nozzle 10 is used. Even if the energy of the second fluid ejected from the nozzle 10 is the same, it can be said that the agitation efficiency is high to generate a larger flow.

[Explanation of cold air conditioners]

A water tank 82 is provided at the lower end of the case body 81, and a partition plate 83 is provided in the vertical direction inside the case body 81, whereby the inside of the case body 81 becomes a wide first chamber 81A. It is partitioned into a second room 81B, which is narrower than that. The lower end of the partition plate 83 is arranged with a gap from the upper surface of the water tank 82.

Inside the first chamber 81A, a water pipe 84 equipped with the three nozzles 10 facing upward at the tip is fixed by a fixture (not shown). The rear end of the water pipe 84 is located outside the case body 81, and is connected to another water pipe 85 connected to the supply pump 86 at that position.
