In addition, the heater 151 may be provided below the heating unit 150, and the steam discharge unit 155 may be provided above the heating unit 150. Since steam has a lighter property than water, the steam outlet 155 may be easily discharged through the steam outlet 155 even when the steam outlet 155 is disposed above.

Between the reservoir 120 and the heating part 150, a connection flow path 180 is provided to allow the water of the reservoir 120 to move to the heating part 150. Meanwhile, the suction passage 13 may be disposed above the connection passage 180.

FIG. 7 is a cross-sectional view taken along line II ′ of FIG. 5.

Referring to FIG. 7, the reservoir 120 according to the embodiment of the present invention includes a reservoir body 121 that forms an appearance and is provided inside the reservoir body 121 to guide movement of water in the reservoir 120. The flow guide 130 is included.

In detail, the reservoir body 121 has a water storage unit 124 in which water is stored and a portion of the reservoir body 121 is opened so that the water flows out of the reservoir body 121 so that water flows out of the reservoir body 121. The part 121a is formed.

The connection passage 180 may be connected to the reservoir outlet 121a.

The flow guide 130 may include a first guide 131 extending in one direction from one side of the reservoir body 121 and a second guide 132 extending in the other direction from the first guide 131. Included.

That is, the first guide 131 and the second guide 132 may extend in different directions.

The flow guide 130 may be formed by combining the first guide 131 and the second guide 132 as separate members, but the first guide 131 and the second guide 132 may be formed as one member. It may be formed integrally as.

When the first guide 131 and the second guide 132 are integrally formed, the second guide 132 may be formed to be bent from an end of the first guide 131. In one embodiment, the flow path guide 130 may be bent in a "b" shape as shown in the figure.

Water stored in the reservoir 120 may be moved along the side of the flow path guide 130 and may flow out of the reservoir 120 through the reservoir outlet 121a.

The flow guide 130 has a bent shape as a whole, the water of the water storage unit 124 may be bent in a plurality of directions, and then may flow out of the reservoir 120. Detailed operation in this regard will be described later in conjunction with the drawings.

Hereinafter, the operation of the steam generating device 100 by the above configuration will be described.

8 is a cross-sectional view showing the action of the water tank and the reservoir according to an embodiment of the present invention.

Referring to FIG. 8, water stored in the water tank 110 according to an embodiment of the present invention may be introduced into the reservoir 120 through the tank opening 115. In this process, the valve member 142 of the cap 140 is opened.

The water in the reservoir 120 flows into the heating part 150 through the connection flow path 180.

Water in the water tank 110 may be introduced into the heating unit 150 via the reservoir 120 according to Pascal's principle.

Pascal's principle means that the pressure exerted on a fluid contained in a closed container is transmitted to all parts of the fluid and the wall of the container containing the fluid without being reduced in size.

The above principle is applied between the water tank 110 and the reservoir 120.

As described above, the pressure of the air inside the reservoir 120 is maintained at atmospheric pressure.

In a state where the cap 140 is coupled to the reservoir 120, when the water tank 110 is seated on the cap 140, the close contact part 145 and the interference part 125 interfere with each other. Then, the elastic member 146 is compressed, the valve member 142 is moved upwards and the tank opening 115 may be opened.

When the tank cap 120 is opened, the water in the water tank 110 falls into the reservoir 120 by gravity, that is, water pressure. In this process, the air inside the reservoir 120 is introduced into the water tank 110 through the cap 140.

Subsequently, when the water level in the reservoir 120 rises and the reservoir opening 129 is shielded, air in the reservoir 120 may flow into the water tank 110 through the tank cap 140. It becomes impossible.

In this state, a vacuum pressure is formed inside the water tank 110, and water of the water tank 110 can no longer flow into the reservoir 120.

On the other hand, when the cap 140 is separated from the reservoir 120, the elastic member 146 is returned to its original position, the valve member 142 is moved downward to shield the upper side of the cap body 141 Done.

The above principle is applied between the reservoir 120 and the heating part 150.

In a state in which water is present in the reservoir 120 or more, if there is no water or a small amount in the heater 150, the water of the reservoir 120 is stored in the reservoir 120 and the heater ( By the difference in the water level of 150 may be moved to the heating unit 150.

The water stored in the reservoir 120 is moved to the heater 150 until the water levels in the reservoir 120 and the heater 150 are the same. That is, when the water level of the reservoir 120 and the heating unit 150 is the same, the water will not move any more.

According to the above structure, since only a small amount of water is supplied to the heating unit 150, the steam generation time by the heater 151 is shortened.

By the above structure, the water of the water tank 110 can be easily moved to the heating unit 150. That is, there is no need for a separate configuration such as a pump or a controller, and there is an advantage in that water can be moved from the water tank to the heating unit 150 by a simple structure.

In addition, since the steam generator can be implemented by a simple structure, there is an advantage that the weight of the nozzle having the steam generator is lighter.

9 is a cross-sectional view showing the inflow of water from the reservoir to the heating unit according to an embodiment of the present invention.

Referring to FIG. 9, when the water level of the reservoir 120 is higher than the water level of the heating part 150, the water stored in the water storage part 124 is guided by the flow path guide 130. It may be discharged through the reservoir outlet 121a.

Water stored in the water storage unit 124 is moved in a direction (first direction) along one side of the first guide 131 or the second guide 132. Here, the flow path formed along the a direction is referred to as "first flow path".

In addition, the flow of water flowing along the first flow path may have a direction opposite to the flow direction of water flowing through the connection flow path 180.

The water moved along the first flow path is bent and then moved along the other side of the second guide 132 in the b direction (second direction). Here, the flow path formed along the b direction is referred to as "second flow path".

In addition, the flow of water flowing along the second flow path may form a direction perpendicular to the flow direction of water flowing through the connection flow path 180.

The water moved along the second flow path is bent and then moved along the other side of the first guide 131 in the c direction (third direction). Here, the flow path formed along the c direction is referred to as "third flow path".

Water moved along the third flow path may flow out of the reservoir 120 through the reservoir outlet 121a and may flow into the heating unit 150 through the connection passage 180.

As described above, the water stored in the water storage unit 124 is a flow that is bent in a plurality of directions before flowing out of the reservoir 120. In addition, the flow path that is moved while the water is bent may be formed differently from the direction of the flow path that is moved through the connection flow path 180.

That is, the water stored in the water storage unit 124 does not flow out directly toward the heating unit 150, but is bent out in various directions by the flow guide 130 so that only a small amount of water flows out of the heating unit ( 150 can be introduced into.

In addition, even when the nozzle 1 is inclined toward the heating part 150 while being shaken or flipped, the water of the water storage part 124 does not flow into the heating part 150 side at a time.

As a result, since only a small amount of water of the water stored in the water storage unit 124 flows into the heating unit 150, the steam generation time in the heating unit 150 may be shortened.

Meanwhile, although the first guide 131 and the second guide 132 are illustrated as being included in the flow guide 130, alternatively, a larger number of guides may be included.

The guides 131 and 132 may be arranged not only in a direction perpendicular to each other but also at various angles.
