The steam guide blade 173 is preferably formed at a position corresponding to the jetting unit 150 and may be integrally formed with the rotary plate 171.

The central disc 171a is provided with a clutch unit 175 and a center shaft 195 is coupled to the upper center of the clutch unit 175 to transmit rotational force from the driving unit 190 to the clutch unit 175.

10 to 13, when the clutch unit 175 is in a state where a load is generated in the rotary plate 171, i.e., the mop 10, the rotational force of the center shaft 195 is transmitted to the rotary plate 171, As shown in FIG. The clutch portion 175 includes a disc receiving portion 175a formed at the central portion of the rotary disc 171 or an upper portion of the central disc 171a and a disc plate 175b mounted inside the disc accommodating portion 175a. And a ball 175c and a spring 175d provided between the disc receiving portion 175a and the disc plate 175b.

The disc receiving portion 175a has a ring structure, and ball interference grooves 176a are formed therein at regular intervals.

The disc plate 175b has a disc shape, and the shaft coupling portion 177 is connected to the center of the disc plate 175b. A plurality of receiving grooves 176b are formed on the outer circumference of the disc plate 175b to receive the ball 175c and the spring 175d. The outer circumference of the disk plate 175b is formed to have a size such as to be in close contact with the inner circumferential surface of the disk accommodating portion 175a so that the disk plate 175b is relatively in contact with the inner circumferential surface of the disk accommodating portion 175b So that it can be rotated by a small distance.

The spring 175d is accommodated in the receiving groove 176b and elastically biases the ball 175c toward the inner circumferential surface of the disc receiving portion 175b so that the ball 175c is brought into contact with the ball interference groove 176a The ball 175c is pushed into the ball interference groove 176a so as to provide a sufficiently large frictional force between the disc plate 175b and the disc receiving portion 175a. Accordingly, the rotational force of the disc plate 175b is transmitted to the rotating plate 171 so that it can be rotated integrally.

When a load is generated in the mop 10 during the cleaning operation while rotating the rotating unit 170 and the mop 10 is unable to rotate due to the stepping on the cleaner main body 110 and the mop 10 being caught by an obstacle, Is transmitted to the rotation unit 170 as it is, the driving unit 190 may be damaged or the rotation unit 170 may be damaged. However, by providing the clutch portion 175 as in the present invention, when the same situation occurs, the ball 175c is disengaged from the ball interference groove 176a by overcoming the frictional force by the pressing force of the spring 175d as shown in Fig. 13 And the disc plate 175b can relatively rotate in the disc accommodating portion 175a. Accordingly, no rotational force is transmitted to the rotating plate 171, and no load is generated in the driving unit 190, so that damage due to the overheating of the driving unit 190 and damage to the rotating unit 170 can be prevented .

As described above, according to the steam cleaner 100 of the present invention, the following actions and effects can be expected.

The steam supply path 160 is not supplied using the central axis of the rotary unit 170 but is supplied to the lower portion of the cleaner main body 110 through a separate connection pipe portion 163 and a branch path 165 It is possible to prevent the steam from flowing back into the cleaner main body 110 or heating the rotating part and the driving part by heat transfer.

In addition, the amount of steam supplied to the lower portion of the cleaner main body 110 can be increased to a sufficient amount. That is, it is easy to expand the flow path of the steam supply path 160, there is no difficulty in structure and design due to the expansion of the flow path, and there is no fear that the steam will flow back into the cleaner main body 110, There is an advantage to be able to. That is, there is an advantage that steam can be supplied in a sufficient amount to the mop 10 which is attached to the rotating unit 170 and rotated without forming a steam flow path through the central shaft. Since the steam path is not used as the central axis, it is possible to fundamentally solve the problem caused by leakage of steam or the like, and it is possible to easily increase the supply amount of steam.

In addition, by configuring the steam spraying unit 150 in the form of a circular arc corresponding to the rotating unit 170 supporting the mop 10, there is an advantage that steam can be uniformly supplied to the entire mop 10.

The steam cleaner 100 according to the present invention includes a steam guide blade 173 formed in an arc shape below the cleaner main body 110 at a position corresponding to the sprayer 150 for spraying steam, The steam can be guided by the mop 10 exposed in the through hole 171c formed in the rotary plate 171 and uniformly supplied.

The steam guide blades 173 are provided at regular intervals in the circumferential direction corresponding to the arc-shaped steam spraying parts 150 so that steam is sprayed from the steam spraying part 150 while being rotated together with the rotation of the rotary plate 171 The steam can be efficiently supplied to the mop 10 and the steam can be uniformly supplied to the mop 10 by the rotation of the blade 173 even if the through hole 171c is formed sufficiently large.

According to the mop rotation unit 170 having the above-described structure, the rotary unit 170 is rotated at a position corresponding to the jetting unit 150, which is installed in an arc shape below the cleaner main body 110 to jet steam, And a clutch unit 175 installed to support the mop 10 to block the rotation of the driving unit 190 from being transmitted to the rotary plate 171 when a load is generated in the mop 10.

Since the transmission of the rotational force to the rotary plate 171 for supporting the mop 10 can be blocked by the clutch unit 175, it is possible to prevent the drive unit 190 from overheating or failing at the time of the occurrence of the load, There is an advantage that breakage can be prevented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Those skilled in the art will readily appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
