In addition, a lower side of the seating plate 116 is provided with a first leg 118 for supporting the water tank 110. A plurality of first legs 118 may be provided at corner portions of the seating plate 116.

In addition, the reservoir 130 has a substantially rectangular parallelepiped shape. The size of the reservoir 130, that is, the capacity for storing water is smaller than that of the water tank 110. Below the reservoir 130, a second leg 138 is provided to support the reservoir 130.

The reservoir 130 has a reservoir opening 132 through which water supplied from the water tank 110 flows. The reservoir opening 132 may be larger than the tank opening 112.

Since the reservoir opening 132 is formed larger than the tank opening 112, the tank cap 120 may be easily extended from the lower side of the tank opening 112 toward the inside of the reservoir 130.

In addition, the reservoir 130 is provided with a restraining portion 135 to interact with the tank cap 120. The restraining part 135 has a shape protruding upward from the lower surface of the reservoir 130.

In addition, the reservoir 130 is formed with an outside air inlet hole 137 through which external air is introduced. When air is introduced through the outside air inlet hole 137, atmospheric pressure may be maintained in the reservoir 130.

Between the water tank 110 and the reservoir 130, a sealing member 114 is provided to prevent water from leaking from the reservoir 130. The sealing member 114 is disposed along the outer circumferential surface of the reservoir opening 132.

One side of the reservoir 130, a heating unit 150 is provided to heat the water introduced from the reservoir 130.

The heating part 150 may have a substantially rectangular parallelepiped shape. Inside the heater 150, a heater 151 is provided to heat water to generate steam. The heater 151 may be disposed at the bottom of the heating unit 150. In this case, a sheath heater, a PTC heater, a ceramic heater, and the like may be applied to the heater 151.

Although not shown in the figure, a felt may be provided below the heater 151 to prevent heat of the heater 151 from being transferred to the surface of the heating part 150. That is, the felt may be referred to as a heat transfer preventing member.

The felt may be arranged to surround the heater 151.

In addition, a heater coupling part 154 to which the heater 151 is coupled is formed on one side of the heating part 150. One side of the heater 151 may be coupled to the heater coupler 154.

In addition, the heating unit 150 is provided with a steam discharge unit 155 to discharge the generated steam. The steam outlet 155 has a pipe shape, a part of which extends into the heating part 150, and the other part of the steam discharge part 155 protrudes out of the heating part 150.

That is, the steam discharge part 155 is disposed to be fitted to one surface of the heating part 150. Of course, the steam outlet 155 will be fixed to one surface of the heating unit 150.

In addition, the steam discharge part 155 is disposed to be located above the heating part 150. In detail, the steam outlet 155 may be disposed at a position higher than the height of the center portion of the heating unit 150. This is because steam generated by the heater 151 is lighter than water and has a property of rising.

As shown in FIG. 5, a plurality of steam outlets 155 may be provided.

In order to allow water to easily flow from the reservoir 130 to the heating part 150, the inlet part 136 may be inclined downward toward the heating part 150.

Hereinafter, the steam generation process by the steam generator 100 will be briefly described.

Water stored in the water tank 110 according to an embodiment of the present invention may be introduced into the reservoir 130 through the tank opening 112. In this process, the valve member 122 of the tank cap 120 is opened.

In addition, the water of the reservoir 130 is introduced into the heating unit 150 through the inlet 136.

Water in the water tank 110 may be introduced into the heating unit 150 via the reservoir 130 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 application of Pascal's principle to the present embodiment is as follows.

(1) P _tank + ρgh _{water_tank} = P _air + ρgh _{water_reservoir}

Equation (1) means that the pressure in the water tank 110 and the pressure in the reservoir 130 is in equilibrium. The pressure in the water tank 110 is the sum of the vacuum pressure of the tank and the pressure by the water stored in the tank, the pressure in the reservoir 130 is the pressure of the air inside the reservoir 130 and the reservoir ( 130 is the sum of the pressures stored by the water. As described above, the pressure of the air inside the reservoir 130 is maintained at atmospheric pressure.

When the tank cap 120 is opened, the water of the water tank 110 falls into the reservoir 130 by gravity, that is, water pressure. In this process, the air inside the reservoir 130 is introduced into the water tank 110 through the lower opening (not shown) of the tank cap 120.

Subsequently, when the water level in the reservoir 130 rises so that the water in the reservoir 130 covers at least a portion of the tank cap 120, the air in the reservoir 130 is transferred through the tank cap 120. It cannot be introduced into the water tank 110.

That is, when the water level of the reservoir 130 rises to shield the lower opening of the tank cap 120, the air of the reservoir 130 may no longer flow into the water tank 110.

In this state, the water tank 110 is formed by the sum of the vacuum pressure and the water pressure by the water level, and the inside of the reservoir 130 is formed by the sum of the atmospheric pressure and the water pressure by the water level. That is, the pressure of the water tank 110 and the reservoir 130 is in equilibrium.

(2) P _air + ρgh _{water _ reservoir} = ρgh _{water _ boiling} + P _{steam & air}

Equation (2) means that the pressure in the reservoir 130 and the pressure in the heating unit 150 is the same. The pressure inside the heating unit 150 is the sum of the pressure caused by the water inside the heating unit 150 and the steam and air pressure inside the heating unit 150.

That is, when there is no water in the heating unit 150 or there is a small amount, water is diverted from the reservoir 130 by the water level difference between the reservoir 130 and the heating unit 150. ) Can be moved.

Therefore, the water level inside the heating unit 150 may be determined by the water level of the reservoir 130.

In summary, the water stored in the reservoir 130 is moved to the heater 150 until the water level in the reservoir 130 and the heater 150 is the same. That is, when the water level of the reservoir 130 and the heating unit 150 is the same, the water will not move any more.

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.

Hereinafter, a shielding device for selectively shielding the inlet 136 will be described with reference to the drawings.

6 to 8, the steam generator 100 according to the embodiment of the present invention includes a reservoir 130 in which water supplied from the water tank 110 is stored, and flows in from the reservoir 130. And a heating unit 150 for heating the water to generate steam, and a shielding device 170 for selectively blocking the water flowing into the heating unit 150.

In addition, an inlet 136 is provided between the reservoir 130 and the heating part 150 to allow water to flow from the reservoir 130 to the heating part 150.

As described above, the inlet 136 may be inclined downward from the reservoir 130 toward the heating unit 150.

The shielding device 170 may move upward and downward through the inlet 136.

On both sides of the shielding device 170, a sealing unit 180 is provided to prevent the leakage of water in the process of flowing water into the heating unit 150 through the inlet 136.

That is, the sealing unit 180 may be provided between the shielding device 170 and the reservoir 130, and between the shielding device 170 and the heating unit 150.

In detail, the shielding device 170 may include a shielding portion 171 for shielding the inflow portion 136 and an opening portion provided under the shielding portion 171 and for opening the inflow portion 136. 172 and a roller 18 connected to one side of the opening 172 to allow the nozzle to be easily moved.

In this case, the roller 18 may be disposed to protrude downward from the nozzle body 18.

In addition, a connection portion 174 is provided between the opening portion 172 and the roller 18. That is, one side of the connection portion 174 is connected to the opening portion 172, the other side is connected to the roller 18.

The shield 171 has a size corresponding to the inlet 136, that is, at least the size of the inlet 136 or more, and is formed in a thin plate shape. When the shield 171 is located at one side of the inlet 136, the inlet 136 may be closed.

The opening portion 172 is formed in a rectangular parallelepiped shape through which the opening 172 passes. An opening 173 is formed in the opening 172, and when the opening 173 is located at one side of the inlet 136, the inlet 136 may be opened.

Similarly, the opening 172 may have a size corresponding to the inlet 136.

In addition, below the opening 173, a spring 175 is provided to provide a restoring force to the roller 18. One side of the spring 175 is fixed to the reservoir 130, the other side may be fixed to the roller 18.

The reservoir 130 is provided with a spring fixing portion 178 to fix the spring 175.

On the other hand, the lower side of the inlet 136, the lower support portion 190 is provided to support the shielding device 170 in the process of moving the shielding device downward.

One side of the lower support 190 is fixed to the reservoir 130, the other side is fixed to the heating unit 150. In addition, the lower support part 190 penetrates through the opening 173 of the opening part 172 and is disposed in a left and right direction.

That is, the lower support part 190 may be formed to be inserted into the opening part 172. In addition, the size of the lower support part 190 may have a size corresponding to the opening part 172.

Hereinafter, the operation of the shielding device 170 will be described with reference to the drawings.

6 shows a state in which the nozzle is supported on the bottom surface, and FIG. 7 shows a state in which the nozzle is lifted apart from the bottom surface.

Steam cleaning is performed while the nozzle is supported on the floor, and the nozzle is generally moved or manipulated when lifted from the floor.

With the nozzle placed on the bottom surface, the roller 18 is supported on the bottom surface. Then, the shielding device 170 is moved upwards, the shielding portion 171 is penetrated through the inlet 136 is located.

That is, the movement flow path of the water formed in the inlet 136 is blocked by the shield 171.

In addition, the spring 175 is compressed, and the lower support portion 190 may be seated on the lower end of the opening 173.

In this process, since the inlet 136 is closed, the inflow of water from the reservoir 130 to the heating unit 150 is blocked. Therefore, the minimum amount of water stored in the heating unit 150 may be maintained.

As a result, in the state in which the inlet 136 is closed, even if the water in the heating unit 150 slack due to the inclination of the nozzle, the water leaks out of the heating unit 150. There is an advantage that it can be prevented.

On the other hand, when the nozzle is spaced apart from the bottom surface, the roller 18 is also spaced apart from the bottom surface. The roller 18 is moved downward by its own weight.

The shielding device 170 is guided by the roller 18 and moved downward.

Then, since the opening 173 is positioned at one side of the inlet 136, the inlet 136 is opened, and the reservoir 130 and the heating unit 150 communicate with each other.

That is, it can be seen that the water movement flow path of the inlet 136 is completed by the opening 173.

In addition, the spring 175 is restored and its length is extended, and the lower support part 190 is in contact with the upper end of the opening 173.

As a result, the shielding device 170 is supported by the lower support part 190 and is no longer moved downward.

As described above, in the state in which the nozzle is supported on the bottom surface, the reservoir 130 and the heating part 150 communicate with each other. And, the water of the reservoir 130 will slowly flow into the heating unit 150 by the principle of Pascal.

That is, since a predetermined amount of water flows into the heating part 150, steam generation time is reduced.
