Since the steam supply device 20 of the steam cleaner supplies steam to sterilize a predetermined object or even iron the cloth, as well as the floor and the wall, the user can conveniently use the steam cleaner according to its function. There is an advantage.

Functions and operations of the steam supply device 20 of the steam cleaner according to the present invention are as shown in Figs.

First, as shown in FIGS. 1 to 3, when cleaning the floor, the steam discharge port 32 is closed by the cover 60.

Thereafter, the steam generated in the water tank 30 by the heating of the heater 40 enters the steam room 50 along the steam supply passage 70, and the steam entering the steam room 50 enters the discharge passage. Flows into (80).

Since the steam introduced into the discharge passage 80 is discharged through the steam discharge hole 90 formed at the bottom, the steam discharged into the steam discharge hole 90 is directly supplied to the mop fixed to the lower surface (not shown). Effectively disinfect the floor, while ensuring that the mop is cleaned of dirt and dust.

Meanwhile, as illustrated in FIGS. 4 to 8, when disinfecting a predetermined object or ironing cloth, the steam discharge port 32 is opened by releasing the cover 60.

Thereafter, the connector 110 of the hose 100 is screwed to the steam room (50).

The steam generated in the water tank 30 by heating the heater 40 enters the steam room 50 along the steam supply passage 70, and the steam entering the steam room 50 is connected to the connector 110. It is introduced into the hose 100 through the steam inlet 112 of the.

The steam introduced into the hose 100 is discharged through the steam injection hole 121 formed in the steam injection mechanism 120, the steam discharged to the steam injection hole 121 is a furniture, such as a sofa, chair, bed, or Try to create an ironing effect that will disinfect other things or crinkle the cloth.

On the other hand, according to a preferred embodiment of the present invention, as shown in Figure 9 to 10, the bottom surface 52 of the steam room 50 (corresponding to the outer top surface of the water tank 30) the water tank ( At least one drain hole 53 is formed in communication with the interior of the 30. The drain hole 53 is for reintroducing the water generated by the condensation in the process of discharging steam through the hose 100 into the water tank 30.

Here, the steam room 50 is a space formed by fixing the cover 51 on the upper surface of the water tank 30, the cover 51 is a packing 54 of the water tank 30 It has a structure that is fixed in close contact with the upper surface.

In addition, the diameter of the drain hole 53 is formed smaller than the diameter of the steam supply passage (70). In addition, although FIG. 9 illustrates the case where two drain holes 53 are formed, if the condition for reflowing water toward the water tank 30 is satisfied, a special restriction on the number and position of formation of the drain holes 53 may be provided. none.

According to the present invention, the bottom surface 52 of the steam room 50 is formed to be inclined at a predetermined angle toward the drain hole 53, such that the slope (C) is formed on the bottom surface 52 is the bottom surface 52 This is to ensure that the water falling into the) is smoothly moved toward the drain hole (53).

In addition, the first entrance portion of the drain hole 53 is formed in a tapered shape to the inside thereof, so that the moisture collected toward the drain hole 53 can be more easily introduced into the drain hole 53.

Accordingly, the moisture generated by the condensation around the steam room 50 including the hose 100 falls to the bottom surface 52 of the steam room 50 and then inclines toward the drain hole 53. Flow along the 52, and eventually the water introduced into the drain hole 53 is re-introduced into the water tank (30).

On the other hand, when the diameter of the above-mentioned drain hole 53 is too small, there is a fear that the drain hole 53 may be blocked by the surface tension of the water collected in the steam room (50).

In addition, most of the steam generated in the water tank 30 is discharged toward the steam room 50 through the steam supply passage 70, but part of the steam is also discharged through the drain hole 53, The steam discharged through the drain hole 53 and the water collected on the bottom surface 52 of the steam room 50, in particular, water around the drain hole 53 may interfere with each other.

In consideration of this point, according to another embodiment of the present invention, as shown in FIGS. 11 and 13, the bottom surface 52 of the steam room 50 has a single communication with the interior of the water tank 30. A guide member 95 is formed to form a drain hole 53 'and guide water (water) re-introduced into the water tank 30 through the drain hole 53' at the lower portion of the drain hole 53 '. It is equipped.

Here, the guide member 95 is in the form of a hollow pipe that is formed in a 'L' shape, the diameter of the drain hole 53 'is to be formed large enough not to be blocked by the surface tension of water.

In addition, according to an embodiment of the present invention, an inclined surface 34 having a predetermined slope D is inclined downward on the inner upper surface of the water tank 30 adjacent to the drain hole 53 ′, and the inclined surface The upper surface of the guide member 95 is in close contact with (34). Accordingly, the guide member 95 naturally faces downward of the water tank 30.

Here, the reason for forming the inclined surface 34 is to allow the water passing through the guide member 95 to flow down toward the lower surface 33 of the water tank, instead of the inclined surface 34 described in the present embodiment In addition, the guide member 95 itself may be modified to be inclined downward.

In addition, the opening direction of the outlet 95a of the guide member 95 is opened obliquely toward the water tank 30. The reason why the outlet port 95a is opened obliquely upward is to avoid the steam generated from the water tank 30 and the outlet port 95a directly facing each other.

Accordingly, the water collected in the steam room 50 passes through the drain hole 53 'and is re-introduced into the water tank 30 via the guide member 95. Since the outlet 95a of the guide member 95 does not directly face the steam (approximately vertically rising) generated in the water tank, the possibility of causing interference with each other can be minimized, and thus, in the steam room 50 It is possible to reduce the risk of the occurrence of the joint.

In addition, the guide member 95 may be more firmly fixed to the inner upper surface of the water tank 30 by a thin plate-shaped fixing plate 72 for supporting the lower surface, as shown in FIG. The fixing plate 72 is fixed to the inner upper surface of the water tank 30 through a fixing member such as a screw, or in the manner to fix the fixing plate 72 to the inner upper surface of the water tank 30 although not shown. Of course, it can be modified.

According to the present invention, the above-described guide member 95 may be integrally formed in the drain hole 53 'or may be molded into a separate part to be coupled to the drain hole 53'.

In addition, according to the present invention, as shown in Figure 13, the inner upper portion of the water tank (30) is bent in a 'L' shape to maintain a state spaced apart at a predetermined interval in a vertical line with the steam inflow passage (70) It is preferable that the shielding plate 71 of the thin plate is provided, the shielding plate 71 is fixed to the inner upper surface of the water tank 30 through a fixing member such as a screw, or not shown, the shielding plate 71 ) Can be used by deforming in a manner that is fixed to the upper surface of the inside of the water tank (30).

Accordingly, the steam generated in the water tank 30 flows freely toward the steam supply passage 70 through a gap formed between the steam supply passage 70 and the shielding plate 71. 50). However, the boiling water generated during the generation of the steam is blocked from flowing directly to the steam supply passage 70 by the screen plate 71.

That is, since the boiling water is bounced vertically with respect to the steam supply passage 70, the above-described boiling water is blocked by the screen plate 71 covering the lower portion of the steam supply passage 70 to supply the steam. It does not flow directly into the flow path 70.

According to another embodiment of the present invention, as shown in FIG. 14, the steam inlet 112 ′ of the connector 110 is configured to open in both directions, so that the steam flows more smoothly than the aforementioned steam inlet 112. It is possible to, and thus may reduce the risk of the occurrence of noise in the steam room (50).

The present invention relates to a steam supply of the steam cleaner, the steam supply of the conventional steam cleaner was mainly limited to the function of supplying steam to clean only the floor, the steam supply of the steam cleaner is not only the floor, Since a separate object can be connected to the hose through the steam spray mechanism to sterilize or iron the cloth, there is an excellent effect that the user can conveniently use according to its function.

In addition, the present invention can be supplied to a large amount of steam in one direction without the loss of steam because the steam flow is connected to the hose and the discharge passage is closed when sterilizing a predetermined object or iron the cloth, There is an advantage to amplify the effect of sterilization and the ironing effect of the cloth.

In addition, since the heater is provided on the outside of the water tank, the present invention is extremely unlikely to corrode the heater unlike the conventional art, and thus has an excellent effect of less failure and long-term use.

In addition, the present invention has a drain hole formed in the bottom surface of the steam room to re-introduce the water generated in the steam room by the condensation around the hose into the water tank to facilitate the steam supply, the moisture in the process of use There is an effect that can prevent the direct discharge phenomenon.

In addition, the present invention is provided with a guide member in the lower portion of the drain hole to prevent the joint generated by the interference of the water and the steam collected in the steam room, while the boiling water is directly introduced into the steam supply passage through the screen plate There is an effect that can be prevented.
