Description

Pedal Type Rotary Dehydration Device {PEDAL-TYPE DEHYDRATOR}

The present invention relates to a rotary dewatering device, and more particularly, by rotating the dehydration basket by stepping on the foot, the pedal-type rotary dehydration that can facilitate the dehydration operation of the rotary mop, towel, socks, mop, etc. effortlessly Relates to a device.

For floor cleaning of public buildings such as offices, restaurants, schools, etc., mops and mops are widely used. The mop should be washed frequently and dehydrated so that water does not flow down. Dehydration by stepping directly on the washed mop with your feet is not effective. Moreover, the floor cleaning using less dehydrated mop has a problem that the cleaning effect is halved, such as water remaining, and the drying time of the floor is delayed, and the water droplets fall on the floor while moving to the place to be cleaned. .

As a prior art proposed to solve such a problem, Patent No. 0604648 discloses a cloth mop cleaning and dehydration apparatus of a method of dehydrating by pressing a mop by pressing on a footrest, and Utility Model Registration No. 0393861 discusses Sangsangbha. The mop box of the method of twisting the mop in the dehydration container is disclosed. In addition, Patent No. 652492 discloses a dewatering device for a mop washing machine of the method of dehydrating by pressing the mop with two pressing panels by operating the pull lever.

The prior art described above is a method of dewatering by manually compressing or twisting a mop, but there is a problem in that the dewatering effect is slightly lowered. Moreover, in order to squeeze or twist the mop, a relatively large force is required for the user.

The above-mentioned crimping or bitting method has been proposed in a rotational dehydration technique, for example, a rotary mop and a rotational dehydration apparatus of Japanese Patent Application No. 3777772 (hereinafter referred to as 772). 1, reference numeral 772 refers to a rotary mop (1: bag, 2: holder, 4: turntable), a bucket (6), a dehydration basket (8) installed inside the bucket, and the user's foot. Consists of a drive device (7) for converting the up and down movement to the rotational force to transfer to the dehydration basket. For reference, the member numerals of the components are as described in No. 772, but the names thereof will be expressed differently for convenience.

More specifically, No. 772 solves the above-mentioned problems in the related art in that the rotating rod mop is dewatered in a rotating manner. However, 772 contains a number of other problems that need to be addressed as follows.

First, the drive device 7 needs to be structurally robust and secured in operation because it obtains a driving force from the user's foot. However, looking at the scaffolding gear portion 73 of the drive device 7 is structurally weak because it is formed in a 'b' shape or 'hook' shape on the side. In addition, the rack gear 731 formed on the scaffolding gear portion 73 is engaged with the main gear 74 to perform the reciprocating motion (using the elastic restoring force of the spring 75). There is a risk that the gear 731 is disengaged from the main gear 74.

Second, since the driving device 7 of the 772 is installed on one side of the bucket 6, when the user steps on the footrest gear 73, the bucket 6 is likely to be pushed to the other side, and thus the convenience of use is inferior. Of course, if the bucket 6 is filled with an appropriate amount of water, the sliding phenomenon is expected to be small, but if the bucket is on a slippery floor, it will also be useless.

Third, in 772, the dehydration basket 8 is fastened or fixed to the rotation shaft 82 to rotate in one direction. In order to increase the dewatering efficiency, a high speed rotation of the rotating shaft 82 is required. In order to implement such a high speed rotation, the frictional force of the rotating shaft 82 should be minimized. The rotating shaft 82 of No. 772 is simply held in the recess 714 formed in the bottom plate 71, and thus the groove 714 Means should be taken to reduce friction with

Fourth, the rotating shaft 82 of No. 772 penetrates through the inside of the water tank 6 and is fastened to the dehydrating basket 8. However, water penetrates through the portion penetrating the inside of the bucket, and there is a problem of leaking into the driving device 7.

Fifth, the footrest gear portion 73 of No. 772 is operated as the tip of the user's toes touching the footrest 731. Therefore, the toe should not slip from the footrest 731.

Sixth, one side of the bucket (6) of 772 includes a space (62) protruding inside the bucket to accommodate the drive device (7). Between the space 62 and both inner walls of the bucket 6 a narrowed space, ie a narrow valley, is formed. Of course, when the space 62 is formed may be designed so that the same golgol is not formed, but the volume of the bucket is reduced by that is not preferable in design. In order to wash the rotary mop in the bucket (6) is formed the golgol shaking the mop several times up and down, the water in the bucket is easy to flow back through the golgol in the washing process. Therefore, the user is inconvenient to adjust the shaking force more carefully so that water does not flow back when cleaning the mop.

The first object of the present invention is to ensure the reliability and structural robustness of the operation by improving the structure of the scaffolding gear.

A second object of the present invention is to prevent the bucket from being pushed during the operation of the scaffolding gear unit or the stepping operation of the scaffolding.

A third object of the present invention is to realize a high speed rotation by minimizing the frictional force of the rotating shaft.

A fourth object of the present invention is to prevent the water in the bucket from leaking into the driving device.

A fifth object of the present invention is to prevent the user's toe part from slipping on the footrest.

A sixth object of the present invention is to prevent the backflow of water in the bucket during the cleaning of the rotary mop.

Pedal-type rotational dehydration device of the present invention is basically, the upper portion of the water tank and the driving device is installed in the mounting portion formed in the water tank in the lower one side of the water tank to switch the vertical movement by the user's foot to the rotary motion, Installed in the bucket is configured to include a dehydration basket receiving the rotational movement.

Specifically, the driving device of the present invention for achieving the first object is composed of a frame, scaffold gear portion, main gear, driven gear. The frame is composed of a bottom plate fastened with a bucket and a pair of vertical side plates formed at both ends of the bottom plate. The scaffolding gear part includes a scaffolding part which is arranged in a frame and is supported by an elastic member, and a reinforcing side plate formed on one side of the scaffolding part, the reinforcing side plate having a long hole and a rack gear having a predetermined curvature. The main gear is formed on one side of the vertical side plate through the long hole and forms a pinion gear meshing with the rack gear. The driven gear meshes with the bevel gear of the main gear to rotate the dewatering basket in one direction through the rotating shaft.

The present invention may be provided with a non-slip means on the bottom of the bottom plate of the frame, or a non-slip means on the bottom of the bucket to achieve the second object.

The driven gear is seated in a seating groove formed in the bottom plate of the frame, and a ball supporting the lower end of the rotating shaft is provided on the bottom of the seating groove. Thus, the third object of the present invention is achieved. In addition, a portion of the rotating shaft penetrating the upper portion of the mounting portion is provided with an airtight holding means for preventing leakage to achieve the fourth object of the present invention. Moreover, the footrest of the footrest part is provided with a slip prevention means, and the 5th objective of this invention is achieved.

On the other hand, in order to achieve the sixth object of the present invention, a blocking plate is provided between the upper portion of the mounting portion formed in the bucket and the dehydration basket. At this time, the blocking plate is preferably provided to be in close contact with the inner wall of the bucket.

According to the present invention, it is possible to secure the structural rigidity of the scaffolding gear portion, and to accurately limit the movement range of the scaffolding gear portion, thereby ensuring the reliability of operation.

In addition, by implementing a high speed rotation of the rotating shaft can increase the dewatering efficiency.

However, when operating the scaffolding gear unit, it is possible to prevent the bucket from sliding even on a slippery floor.

As a result, the water inside the bucket can be prevented from leaking to the driving device.

In addition, convenience of use can be improved by preventing a user's toe from slipping from a footrest.

In the process of cleaning the mop, water in the bucket can be prevented from flowing back through the iliac bone.

Specific features and effects of the present invention will become more apparent from the following detailed description based on the accompanying drawings. It should be noted that, if it is determined that the detailed description of the known functions and the configurations related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 and 3 is a view showing a schematic configuration of a pedal-type rotary dehydration device (hereinafter, referred to as a rotary dehydration device) according to an embodiment of the present invention, the rotary dehydration device (A) is an upper bucket 100 is open And, mounted on the bucket 100 is a drive device 200 for converting the vertical movement (stepping movement) by the user's foot into a rotary motion, and installed in the bucket 100 to the rotational movement of the drive device 200 And an approved dehydration basket 300.

Bucket 100 is formed to have a predetermined volume to accommodate the water for washing or to receive the dehydrated water, is provided with a mounting portion 110 which is a space protruding into the bucket from the lower one side. The driving unit 200 is mounted to the mounting unit 110. Referring to FIG. 4, narrow valleys 120a and 120b are formed between the inner sidewalls of the bucket 100 facing both sidewalls of the mounting unit 110. The iliac bone may here be designed not to be formed. However, the absence of the iliac bones means that the volume of the water tank is reduced.

As described above, in order to wash the mop in the bucket 100, the mop is shaken up and down in a state of soaking the mop. Accordingly, the water contained in the bucket 100 is rumbled up and down in the bucket, and it is apt to flow back along the above-described iliac bone. Therefore, it is inconvenient for the user to carefully adjust the shaking force in consideration of this. The present invention may include a configuration that can prevent the backflow caused by the iliac in view of such inconvenience. This will be described later.

Referring to FIG. 5, the bottom surface of the bucket 100 may be provided with non-slip means 1 such as a rubber pad, and a handle 3 for convenience of movement and gripping may be provided near the upper portion. The non-slip means (1) can be applied in various ways in the form of covering the entire bottom surface of the bucket or in the form provided in a portion or one or more of the bottom surface.

6 and 7, the driving device 200 includes a frame 210, a scaffold gear unit 220, a main gear 230, and a driven gear 240.

The frame 210 is composed of a bottom plate 211 and vertical side plates 213a and 213b formed vertically at a predetermined height at both ends of the bottom plate. The fastening hole 5 formed at the outer circumference of the bottom plate 211 enables screwing with the bucket 100. In addition, the bottom of the bottom plate 211 may be provided with a non-slip means 7, such as a rubber pad (see Fig. 5).

The footrest part 221 of the footrest gear part 220 is rotatably arranged on the upper end of the vertical side plate of the frame, and is supported by the elastic member 9 on the right vertical side plate 213b on the drawing. The scaffold shaft 11 formed at the upper end of the scaffolding part 221 is fastened to the shaft hole 13 formed at the upper end of the vertical side plates 213a and 213b by the shaft tube 15 and the bolt 17. At the lower end of the footrest portion 221, a footrest 19 which is in contact with the foot of the user, more precisely, the toe is formed. The upper surface of the footrest 19 is provided with a non-slip means 21, such as a rubber pad or protrusion, to prevent the user's toe slips from the footrest during the up and down stepping operation.

 Referring to 8, the one side surface of the scaffold 221 is integrally formed with a reinforcement side plate 223 having a substantially fan shape to structurally reinforce the scaffolding gear 220. The reinforcing side plate 223 is provided with a long hole 23 having a predetermined curvature and a rack gear 25 having a predetermined curvature in the vicinity of the lower hole. Here, the curvature of the long hole 23 and the rack gear 25 is the same.

The main gear 230 is arranged in the left vertical side plate 213a on the drawing through the long hole 23 of the reinforcing side plate 223 (see FIG. 7). 9 and 10, a pinion gear 231 meshing with the rack gear 25 is formed on one surface of the main gear 230, and a bevel gear 233 is formed on the other surface of the main gear 230. Since the rotation range of the scaffold gear 220 is limited by the length of the long hole 23, the engagement state is maintained without being separated from the driven gear 230.

10 and 11, the driven gear 240 is seated in the mounting groove 27 formed in the bottom plate 211 of the frame 210 and is engaged with the bevel gear 233 of the main gear 230. The driven gear 240 includes a shaft insertion through hole 242 for receiving the rotation shaft 201 and a one-way clutch bearing 244 for rotating the rotation shaft 201 in one direction, preferably clockwise (CW). According to a feature of the present invention, the bottom surface of the seating groove 27 is provided with a metal ball (B) to minimize the contact (frictional force) with the lower end of the rotating shaft 201. Therefore, the rotation shaft 201 can rotate more smoothly.

The dewatering basket 300 is coupled to the upper end of the rotating shaft 201 penetrating the upper portion of the mounting portion 110, as illustrated in Figure 12 receives a rotational force. The dehydration basket 300 is formed in a cylindrical shape of a predetermined depth with an open top, and has a plurality of drain holes 310 across the bottom and the periphery to facilitate dehydration. Preferably, the dehydration basket 300 may further include a plurality of locking protrusions 320 formed on the inner circumferential surface to suppress the flow of the mop during rotation.

Since the rotating shaft 201 penetrates the mounting unit 110 as described above, a leakage in the penetrating portion, that is, a leakage to the driving device 200 may occur. In order to prevent this, the through part may be provided with an airtight holding means 29. The airtight holding means 29 may be understood as a packing through which the rotating shaft 201 penetrates, and a metal ring or lidena may be used. The reference numeral 31 in FIG. 12 is located on the airtight holding means and may be omitted or a plastic ring for reducing friction with the dehydration basket (300). Reference numeral 33 is a fixing ring for preventing the rotation shaft 201 is separated from the upward.

Meanwhile, as illustrated in FIGS. 13 and 14, the blocking plate 35 may be provided on the mounting unit 110 to be in close contact with the inner wall of the bucket 100. Accordingly, the water of the bucket 100 is prevented from flowing back to the golgol (120a, 120b) (see Figure 4) in the process of washing the mop, the user can more easily wash the mop.

Hereinafter, the operation of the rotary dehydration device (A) having the above configuration will be described.

First, the dehydration object of the mop, towel, socks, rag in the dehydration basket 300, as shown in Figure 15, the footrest 19 of the drive device 200 exposed to one side of the bucket 100 When pressed, the scaffold 19 is rotated downward about the scaffold shaft 11. As a result of the descending rotation of the foot plate 19, the reinforcement side plate 223 is rotated inwardly of the water tank 100, and the pinion gear of the main gear 230 engaged with the rack gear 25 of the reinforcement side plate 223 is engaged. 231 rotates counterclockwise (CCW) as shown in the figure. Then, the driven gear 240 engaged with the bevel gear 233 of the main gear 230 rotates clockwise (CW), and the one-way clutch bearing 244 installed on the driven gear 240 rotates with the rotating shaft 201. Bind to rotate the spin basket 300 in the clockwise direction. Since the lower end of the rotating shaft 201 is supported by the ball (B), the rotation of the rotating shaft 201 is made more smoothly.

Next, as illustrated in FIG. 16, when the pressed state of the down-rotated scaffold 19 is released, the rack gear 25 rotated inwardly of the water tank 100 by the restoring force of the elastic member 9 is returned to its original position. The main gear 230 rotates in the clockwise direction, and the driven gear 240 rotates in the counterclockwise direction as it is rotated in the outer direction of the bucket. At this time, since the driven gear 240 rotates in the counterclockwise direction, the one-way clutch bearing 244 is released from the rotation shaft 201. Therefore, the rotational force of the main gear 230 is not transmitted to the rotation shaft 201, and the dewatering basket 300 coupled to the rotation shaft 201 maintains rotation in the clockwise direction.

When the pressing and releasing of the scaffold 19 is repeated (stepping operation), the dehydration basket 300 accelerates and rotates only in a clockwise direction, and as a result, dehydration of the dehydration object accommodated in the dehydration basket is performed.

For reference, since the driving device 200 is installed at one side of the bucket 100, when the footrest 19 is stepped on, the bucket 100 may be pushed to the other side. However, the present invention is prevented by the sliding means (1) provided on the bottom surface of the bucket (100) and the non-slip means (7) provided on the bottom plate 211 of the frame 210.
