Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a humidifying device that generates steam.

(Prior Art) Conventionally, a humidifying device used alone or attached to a stove for humidifying a room has a water tank provided in the main body, as shown in, for example, Japanese Utility Model Application Publication No. 57-6918. A heating tube equipped with a heating element is connected, and this heating tube is connected to a steam spout provided at the top of the main body via a connecting tube. The water supplied from the water tank to the heating tube is heated to a boiling state by the heating element, and the steam generated here is released from the connecting tube through the steam port.

In such heating type humidifiers, boiled water becomes fine granular nucleate boiling or large film boiling to generate steam, but especially in the case of film boiling, it becomes bubbles and steam When the steam rises to a nearby point, it ruptures and the scattered hot water droplets are scattered outside through the steam spout, potentially causing burns.

In addition, if the water in the water tank becomes low while the electricity is being used and you want to supply water to the water tank, water may be poured into the water tank from the steam port using a kettle, etc., and then led to the water tank via the connecting pipe and heating pipe. In such cases, large air bubbles may accumulate in the pipes, locking them, and causing water to overflow from the steam opening even though the water tank does not contain the specified amount of water.

In order to deal with such problems, conventional
As shown in Publication No. 58-33, the upper part of the heating tube connected to the water tank is bent forward, and the steam spout fitting is connected to the front end of this heating tube via a connecting pipe. However, inside this fixture, an arc-shaped scattering prevention plate is installed that faces the opening of the connecting pipe, and this scattering prevention plate prevents hot water droplets from scattering outside and causing burns to the user. There are known devices designed to prevent this.

However, even in this case, bubbles may still remain in the pipe and the pipe may become locked.

(Problems to be Solved by the Invention) As described above, the heating type humidifier has the problem of not only the scattering of hot water droplets to the outside but also the problem of locking when pouring water.

This invention aims to improve the above-mentioned points by preventing hot water droplets from scattering to the outside from the steam spout, and preventing locking when pouring water, so that it can be used safely. The purpose is to

[Structure of the idea]

(Means for solving the problem) The present invention provides a water tank in the main body, connects a heating pipe equipped with a heating element to this water tank, and connects this heating pipe to the main body through a connecting pipe. In a humidifier connected to a steam port provided at the top, the steam port also serves as a water supply port, and a dividing plate is provided in the vertical direction at the center of the connection port that is connected to the connecting pipe at the bottom of the steam port, An inclined scattering prevention plate is provided at the upper end of this dividing plate.

(Function) In the present invention, water supplied from the water tank to the heating tube is heated to a boiling state by the heating element, and the steam generated here is released from the steam spout via the connecting tube.

At this time, the large bubbles that rise as a film boiling state are divided by the dividing plate as they rise and become finer, and the large bubbles do not reach the upper end opening of the connection port of the steam mouth body and burst. Even if a small bubble bursts at the upper end opening of the connection port, the droplets are prevented from scattering outward by the scattering prevention plate.

In addition, even if large air bubbles are generated in the connecting pipe and heating pipe when the water in the water tank becomes low and water is injected from the steam port while the water is being energized, the large air bubbles will rise and the dividing plate will be removed. The small air bubbles rise along the slope from the space below the inclined scattering prevention plate where water is not directly injected, and do not escape to the outside and lock the pipe line.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

1 is a main body, a water tank 2 is provided in the main body 1, a water inlet 3 is formed on the lower rear end of the water tank 2, and a heating member made of a copper pipe or the like is connected to the water inlet 3 via a joint 4. A tube 5 is connected and erected, a heating element 6 such as a heating wire is wound around the outer periphery of the heating tube 5, and a flexible connecting tube 7 made of silicone rubber or the like is attached to the upper end of the heating tube 5. The lower end of is connected.

Further, a box-shaped steam port 8 is attached to the upper part of the main body 1 and serves as a water supply port. The upper end of the connecting pipe 7 is connected to the mouth 9 .

In addition, a dividing plate 11 is provided in the vertical direction at the center of the connection port 9 of the steam port body 8, and an inclined circular scattering prevention plate 1 is provided at the upper end of the dividing plate 11.
0 is provided integrally. The dividing plate 11 also reinforces the scattering prevention plate 10.

Furthermore, in the upper opening of the steam mouth body 8,
A cover 13 having a large number of through holes 12 is fitted so as to be openable and closable.

Note that a drain port communicating with the outside may be provided at the top of the water tank 2.

Further, when this humidifying device is attached to an electric stove or the like, as shown in FIG. 2, an electric heating section 14 may be provided in the main body 1, and the humidifying device may be disposed on one side of the main body 1.

In the figure, reference numeral 15 indicates a leg body provided at the bottom of the main body 1.

In such a configuration, the water in the water tank 2 is supplied from the water inlet 3 to the heating pipe 5 at the same level and is heated to a boiling state by the heating element 6, and the steam generated here is converted into steam via the connecting pipe 7. It is released from the through hole 12 in the cover 13 of the mouth body 8.

At this time, the large bubbles that rise as a film boiling state are divided by the dividing plate 11 and become smaller as they rise, and the large bubbles do not reach the upper end opening of the connection port 9 of the steam port body 8 and burst. Even if a small bubble bursts at the upper end opening of the connection port 9, the scattering prevention plate 10 prevents the hot water droplet from scattering outward.

In addition, even if large bubbles are generated in the connecting pipe 7 and heating pipe 5 when the water in the water tank 2 becomes low and water is injected from the steam port 8, which also serves as a water supply port, during energized use, Large bubbles rise and are divided by the dividing plate 11, and small bubbles rise along the slope from a space below the inclined anti-scattering plate 10 where water is not directly injected,
It will not escape to the outside and lock the pipe.

[Effects of the invention] According to the invention, when steam is generated, the large bubbles that rise as a film boiling state are divided by the dividing plate and become finer as they rise, and the large bubbles are disposed at the upper end opening of the connection port of the steam mouth body. Even if a small bubble bursts at the upper end opening of the connection port, the droplets will be prevented from scattering outward by the scattering prevention plate. When the water in the water tank becomes low and water is injected from the steam port, which also serves as a water supply port, even if large bubbles occur in the connecting pipe and heating pipe, these large bubbles will rise and close to the dividing plate. The small air bubbles rise along the slope from the space below the inclined scattering prevention plate where water is not directly injected, and do not escape to the outside and lock the pipe, but Therefore, it is possible to prevent hot water droplets from scattering in the steam spout body, and to prevent locking of the pipe line due to air bubbles when water is poured, so that it can be used safely.
