Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an improved wet mop. More specifically, the invention relates to collecting dirty water from a floor to obtain a clean and almost dry floor surface,
The present invention relates to a cordless wet mop including a rubbing device and a vacuum device.

[0002]

2. Description of the Related Art Mops for cleaning floor surfaces generally have an absorbent mop or sponge head and some squeezing mechanism for squeezing dirty water from the mop or sponge head. In particular, mop is typically used with a bucket of cleaning liquid consisting of water and cleaning additives. The mop absorbs the cleaning liquid used to rub the floor. If the mop becomes soiled by rubbing the floor, the mop is reinserted into the bucket and the mop is washed to further absorb the cleaning liquid. When a dirty mop is repeatedly put into the cleaning liquid in the bucket, the cleaning liquid in the bucket is immediately soiled, and the cleaning performance is reduced in the subsequent mop operation. Therefore, it is desirable to prevent the cleaning liquid from being stained during the floor cleaning operation. Further, in the conventional cleaning using a mop and a bucket, it takes about 15 minutes to dry the floor, and it is desirable that the drying time can be eliminated.

[0003]

A suction squeegee (rubber duster) for removing a cleaning liquid from the floor surface after cleaning has been already proposed. One such suction squeegee device is disclosed in U.S. Pat. No. 5,067,199. However, in this suction squeegee apparatus, since the floor must be cleaned using a normal mop and bucket before using the apparatus, the problem that the bucket of clean water gets dirty remains. Further, this suction squeegee has the disadvantage that three or four separate devices are required to perform the cleaning operation. That is, a suction squeegee, a mop, a mechanism for squeezing dirty water from the mop, and a bucket are required.

[0004] Another previously described suction cleaning device is a combined device for rubbing and removing moisture for cleaning and drying the floor surface. This device has a clean water / sewage tank with a flexible membrane inside to separate clean and dirty water. Clean water from the tank is supplied from the wash nozzle. The nozzle has bristles or brushes for rubbing. After the rubbing operation, the suction system is activated to remove dirty water from the floor and collect the dirty water in the tank.

Devices combining rubbing and water absorption are disclosed in US Pat. Nos. 2,986,764, 3,020,576, 3,040,
Nos. 362, 3,040,363 and 3,060,484. The devices described in these patents have several disadvantages. For example, the equipment is bulky and heavy, cumbersome to handle, requires power supply cords to disturb the user, and the safety implications associated with using household voltages with water-filled equipment. It is a problem.

[0006]

A cordless wetting mop / vacuum device according to the embodiment of the invention is shown in FIGS. The apparatus generally comprises a housing 12, a handle body 10 connected thereto, a removable clean water bottle 14, and a removable sewage tank 16. A cleaning element is mounted within the housing 12 and includes a retractable sponge 18, a pair of squeegees 20, a battery pack 22, a suction motor 24, a suction fan 26, and a suction motor. And a switch 30 for performing the operation. The clean water bottle 14 has a plunger 28 for mixing clean water and the cleaning solution and supplying them to the floor. The sponge 18
It is pulled out of the housing 12 when rubbing the floor, and is drawn into the housing during the suction operation. Retraction of the sponge 18 activates the suction motor 24, which causes the suction system to begin drawing water from the floor into the sewage tank 16. While suction is being applied, the squeegee 20 shown in FIGS. 3 and 4 is pulled over the floor,
Collect dirty water and make floor almost dry.

The handle body 10 has an upper handle 40, which is a foam material handgrip 4.
2 and a cap 44. The cap 44 preferably has a "swivel" that can be used to hang the device to a wall. The upper handle 40 has a spiral insert 46 so that the upper handle can be screwed over the lower handle 48. The lower handle 48 has at least two bolts 5
0 is an integral handle fixed in the housing 12. The integral lower handle 48 is preferably a plastic molding and has a threaded portion that mates with a female threaded insert 46 to provide support for the iris handle 52 and the lower handle 48 to the housing 12. Means for attaching. The aperture handle 52 is pivotally connected to the lower handle 48 by a first pivot 54 and to a rod 56 by a second pivot 58. The aperture handle 52 is configured to have two legs 60, and each leg 60 extends so as to sandwich both sides of the lower handle 48. The flat end of the rod 56 is inserted between the two legs 60, and the rod 56 is pivotally connected to the legs by pins passing through the rod and the legs. Rod 56 extends through housing 12 along lower handle 48. The opposite end of the rod 56 penetrates a metal bracket 64 to which the sponge 18 is attached.

The operation of the aperture handle 52 causes the sponge 18 to be extended or retracted, and at the same time, the suction motor 24 is turned on and off via the switch 30. Aperture handle 52 moves sponge 18 between three positions. In the extended position shown in FIG.
Extends fan-shaped beyond the pair of sponge rollers 62 attached to the bracket 74. In the extended position, the metal bracket 64 abuts against the roller 62 to hold the sponge in the desired cleaning position. To retract the sponge 18, the squeeze handle 52 is moved in the direction of arrow A, ie, away from the upper handle 40. Aperture handle 5
As 2 is moved, rod 56 pulls the sponge upward. When the sponge 18 is retracted, the sponge 18
Is squeezed by the rollers 62, whereby the water absorbed by the sponge is squeezed out onto the floor.

FIG. 2 shows the sponge 18 in the retracted position. In this position, the sponge 18 is housed in the metal bracket 64, the tip of the sponge protruding a small distance from the tip of the roller 62. This distance is preferably between 0.1 inches and 0.5 inches. The sponge 18 is maintained in the retracted position by expanding the portion of the sponge located behind the roller 62. Further, a detent depression (not shown) may be provided in the aperture handle 52 to hold the sponge 18 in the retracted position.

The squeeze handle 52 is also used to remove the sponge 18 for replacement or cleaning. The sponge 18 is removed by moving the squeeze handle 52 in the direction of the upper handle 40, that is, in the direction of arrow B. As a result, the sponge 18 and the metal bracket 64 pass between the rollers 62 that are deflected and separated in the drawing bracket 74.

The squeeze handle 52 also turns the suction motor 24 on and off by operating the switch 30 with the protruding bent portion 66 of the rod 56. In this way, the suction motor 24 is operated only when the sponge 18 is being retracted. As a result, the operation of the motor is stopped when it is not necessary, so that the battery power can be saved, and the battery power of the battery pack 22 is saved. As shown in FIG. 2, when the sponge is retracted, the protruding bent portion 66 of the rod 56 passes over the switch 30 and turns on the suction motor 24.

Generally, a single 12-14 amp permanent magnet motor can be operated for 5-10 minutes with a single 5-volt 6-volt battery pack 22. Since the suction motor 24 is operated only when suction is necessary, the battery pack 2
2 can be used for floors of at least 250 square feet without requiring recharging. The battery pack 22 is shown more clearly in FIG. 5, which is an enlarged view of the central part of FIG. Battery pack 22 is preferably a 6 volt rechargeable battery pack,
It can hold up to 6 cells and is housed in the battery space 68 in the housing 12. The battery pack 22 is fixed at a fixed position in the space by a fixing member 70. The fixing member 70 can be rotated around the lower handle 48. Two protrusions 72 on the lower handle hold the securing member 70 in the proper axial position on the lower handle. The fixing member 70 is in the non-fixing position in FIG.
In FIG. 2, it is in a fixed position.

When the battery pack 22 is in the battery space 6

Are in contact with each other. The suction motor 24 is mounted in a motor mounting body 82. This is by conventional means, for example, by mounting in a pair of saddles built into the housing 12. The suction motor 24 is preferably a permanent magnet DC motor, for example, 12 to 1
4 amp, 6 volt strontium magnet motor, output about 18,000-25,000 rpm, preferably 21,000-22,000
rpm. As shown in FIG.
4 is separated from the adjacent fan chamber 84 by a resilient grommet 86. This grommet 86
Prevents water entering the fan chamber from entering the motor.

The suction motor 24 used in the present invention is of a self-cooling type and does not require a cooling fan.
However, a motor fan may be added if necessary. Preferably, a vent 88 is provided on the side of the housing 12 to allow air circulation to the motor. The fan chamber 84 also has an exhaust passage 90 through which exhaust gas can pass. The lower part of the housing is better shown in the enlarged view of FIG. In this part, the sponge 18, the squeegee tray 92,
The sewage tank 16, the fan chamber 84, and the suction fan 26 are included.

The squeegee tray 92 has two elongated squeegees 20, which are fitted into the squeegee tray 92 in a known manner. The squeegee 20 is 5 to 20 inches long, preferably 8 to 12 inches long. Squeegee tray 92 has suction inlet 94
Having. The suction inlet 94 is a long elliptical opening located between the two squeegees 20 and at the center of the squeegees 20, about one-half of the entire length of the squeegees 20.
It extends from / 4 to の 長 in length. Water is squeegee 2
Through the entire length of 0, it is sucked into the suction inlet 94 from the open end between the squeegees 20. Both the cross-sectional area of the flow path between the two squeegees and the floor and the cross-sectional area of the suction inlet 94 are dimensioned to provide the necessary air velocity to transport the water droplets into the air. Operating at a speed between about 1000 feet and about 3000 feet per minute or more, water droplets are carried into the air.

A set of wheels 122 is mounted on the squeegee tray 92 so that the entire device can be easily rolled around the floor during rubbing, squeegeeing, or moving. The squeegee 20 is mounted in parallel in the squeegee tray 92 so that both squeegees are in contact with the floor when the device is rolled on the floor. When the sponge 18 is at the dispensing position, the sponge is dispensed beyond the squeegee 20, and the squeegee 20 does not contact the floor. The center plane X bisecting the sponge 18 is located at an angle α with respect to the Y plane of the squeegee. This angle α is between about 10 degrees and about 30 degrees, preferably about 25 degrees. The upper surface of the squeegee tray 92 is provided with an elliptical groove 96 surrounding the suction inlet 94. In order to seal between the suction inlet 94 and the central pipe 100 of the sewage tank 16, an elastic sealing member 98 is provided in the groove 9.
6 inside. The elastic seal member 98 is preferably made of compressible sponge rubber, in which case the tank 16 is urged upward and the sewage tank 16 is
Once inserted in the tank 2, the tank 16 is held in an appropriate position.

The squeegee 20 is formed such that one side has a smooth end and the other side has a serrated end. The two squeegees 20 are positioned such that their smooth sides face each other.
It is arranged inside. With such a structure, when the apparatus is moved on the floor, both squeegees make contact with the floor and bend. With the serrated end of the first squeegee in contact with the floor, water passes under the first squeegee. This water is trapped by a second squeegee whose smooth end is in contact with the floor. In this way,
The device can be used while the user is moving forward and backward on the floor. Water is collected from between the two squeegees by the flow of air from the open end between the two squeegees to the central suction inlet 94.

Water is supplied from the central suction inlet 94 to the sewage tank 1.
Pass to 6. The sewage tank 16 has a central tube 100 built therein. Central pipe 100 is tank 1
It extends sufficiently high within 6 to obviate the need for a closing member for closing the central tube to prevent leakage when the tank 16 is removed for emptying. The cover 102 is placed inside the upper end of the tank 16, and the edge is sealed to the tank by an O-ring 104. Opening 1 in cover 102
06, through which air passes from the tank 16 to the fan chamber 84. The cover 102 further includes a baffle 108 that diverts the water drawn into the tank 16 through the central tube 100. Cover 1
There is a face seal 116 around the opening 106 of 02, which seals the flow path between the sewage tank 16 and the fan chamber 84.

The central tube 100 and the baffle 108 are located inside the tank 16 and are arranged so that most of the capacity of the sewage tank 16 can be utilized when operating at an angle. Furthermore, if the sewage tank 16 is partially filled, the sewage may enter the fan chamber 84 through the central pipe 100 or the opening 106 even if the apparatus rear surface 118 is laid down on the floor. There is no.

The assembly of sewage tank 16 and cover 102 is adapted to be removed from housing 12 for emptying and cleaning the water. Tank 1
6 is inserted and fixed in the housing so that the bottom of the tank contacts the seal member 98. After the tank 16 is inserted, the tank 16 is fixed in place by the latch 110. The latch 110 is slidably mounted along the outside of the tank 16 and has a protrusion 112. The protrusion 112 is received in a corresponding recess 114 in the housing 12. The cover 102 of the sewage tank 16 may have one or more detent recesses 120 such that the tank 16 remains within the housing 12 during operation of the latch 110.

The suction system includes two squeegees 2 through a suction inlet 94 and a central pipe 100 of the sewage tank 16.
It operates by drawing air from the open end between zeros. The speed of air is the speed at which water droplets are conveyed into the air. Water strikes the baffle 108 in the tank 16 and is redirected downward toward the tank interior. The velocity of the air decreases as it enters the tank 16 from the central tube 100, and water droplets contained in the air fall into the tank. The air then passes both outside of the central tube 100, enters the fan chamber 84 through the opening 106, and flows out of the housing 12 through the ventilation fan 90 through the suction fan 26. In the tank, a baffle 108 is used to reduce the velocity of the air so that the water drops from the air stream.
The cross-sectional area of the air passage in the tank between the opening 106 and the opening 106 must be larger than the cross-sectional area of the central pipe 100. As the air velocity in the tank drops below about 1000 ft / min, water remains in the tank.

The sewage tank 16 may further include a control device for stopping suction when the tank 16 reaches a certain water level. This control device may be, for example, a float device that closes the tank opening 106 when the tank 16 is full. The motor used may have an automatic stop function. For example, a motor with a 9 inch seal suction will automatically shut off when the tank is filled to 9 inches.

Prior to the rubbing step, a cleaning solution is provided on the floor by a clean water bottle 14. Clean water bottle 14
Is removably attached to the front face 124 of the housing. The washing solution or washing solution used in the clean water bottle according to the invention may be any known washing solution or mixture thereof, for example water plus detergent.
