Description

Invention Field

[0001] This patent disclosure generally relates to buckets, and more specifically, to buckets for rinsing cleaning devices such as mops. Background Technology

[0002] Floor mops are typically used in conjunction with a bucket containing a rinsing solution (e.g., water and / or cleaning fluid) to replenish the water in the mop head or to rinse it. However, after applying the mop head to the surface to be cleaned, putting the mop head back into the rinsing solution can contaminate the surface with dust that was removed from the cleaned surface. Repeatedly dipping the mop head into the rinsing solution and using it on the surface increases the dust level in the rinsing solution and may reduce the system's ability to clean the surface. Emptying the bucket to obtain a clean rinsing solution environment can be inconvenient and time-consuming. Emptying the bucket to obtain a clean rinsing solution also increases water consumption and may increase cleaning fluid consumption.

[0003] The Embell system is a bucket system that provides a bucket with two separate chambers for receiving mop heads. A rinse valve is actuated to measure a predetermined amount of rinse fluid entering the first chamber for each rinse of the mop head. After rinsing the mop head in the first chamber, the rinsed mop head is placed in the second chamber, where it is squeezed to dry it before application to subsequent surfaces. Squeezing the mop head separates excess rinse water from the mop head, which is automatically drained into a dirty water tank. While the mop head is being squeezed in the second chamber, the same force is applied to open the drain in the first chamber, thereby expelling any remaining rinse fluid from the first chamber. When the mop head is removed from the second chamber, the operator can use the mop handle to actuate a clean water valve adjacent to the second chamber to again measure the predetermined amount of rinse water entering the first chamber. Summary of the Invention

[0018] This disclosure relates to a bucket assembly 10 for a mop. While the mop itself is not specifically described, those skilled in the art will understand that a mop will have a shaft and a mop head, which typically includes one or more absorbent structures. An exemplary interior of a representative mop head 100 is shown in the figures as a generally triangular structure, which is described in detail below. References are made to... Figure 1 , Figure 2 Exploded diagram and Figure 3A and 3B The embodiment of the bucket assembly 10 illustrated in the cross-sectional view includes an inner bucket assembly 12 partially received in an outer bucket assembly 14, and has a rinsing bucket 16 for rinsing the mop head and a drain channel 18 for receiving excess fluid from the mop head.

[0019] The inner tub assembly 12 includes a rinse tub 16 and a first reservoir 20, which is fluidly coupled to the rinse tub 16 via a fluid connector 22. The inner tub assembly 12 may also include a filling opening 24 leading to the first reservoir 20 and a plug 26 sized to seal the filling opening 24. While alternative designs are possible, in the illustrated embodiment, the plug 26 is coupled to the inner tub assembly 12 via an arm 28, which may be coupled to the inner tub assembly 12 via an engagement structure such as a rivet 30. The first reservoir 20 can be used to contain rinse fluid for supply to the rinse tub 16, allowing the mop head to be placed in the rinse tub 16 to contact the rinse fluid. The rinse fluid can be any suitable fluid, such as water, water with a cleaning solution, or another cleaning solution.

[0020] The fluid connection 22 can be selectively opened and closed by at least one closure element 32. While alternative arrangements may be provided, in the illustrated embodiment, the closure element 32 is an elongated structure 34 slidably received in an elongated recess 36, which is laterally attached to either side by a flange 38. For ease of operator movement, the closure element 32 includes a handle or protrusion 40 at its upper end. Similarly, the inner tub assembly 12 may include a depression or notch 42 disposed substantially adjacent to the protrusion 40 in the assembly. The notch 42 allows the operator to easily grasp the protrusion 40 and slide the elongated structure 34 of the closure element 32 within the elongated recess 36 to selectively open and close the fluid connection 22.

[0021] To allow flow from the first reservoir 20 to the flushing tank 16, the sealing element 32 can be removed from... Figure 3A The closing position described in the document is moved to... Figure 3B The opening position is as described in the document. When the closing element 32 is in the closed position ( Figure 3A Move to the open position ( Figure 3B When the first liquid storage tank 20 and the rinsing tank 16 are in the open position, the fluid connection 22 between them is gradually opened. Conversely, when the closing element 32 moves from the open position to the closed position, the fluid connection 22 between the first liquid storage tank 20 and the rinsing tank 16 is gradually closed.

[0022] The inner tub assembly 12 may further include one or more pawls or other mechanisms that facilitate holding the closure element 32 in a specific position relative to the fluid connection 22 and the elongated notch 36. For example, multiple protrusions and / or notches may be provided along the closure element 32 and the flush tub 16. Engagement of the protrusions with the notches and other surfaces may provide pawls that help hold the closure element 32 in a specific position.

[0023] refer to Figures 4 to 7In at least one embodiment, the closure element 32 may include one or more protrusions 152, 154, 156 and a recess 164, and the flushing tub 16 may include one or more protrusions 160 and a recess 162. More specifically, the protrusions 152 may be positioned along the closure element 32 such that when the closure element 32 is positioned in the closed position (see...). Figure 3A , 5 When 7), the protrusion is adjacent to the edge of the fluid connector 22. In this way, the protrusion 152 is positioned against the edge of the fluid connector 22 and the distal end of the closure element 32 adjacent to the surface of the flushing tank 16 to hold the closure element 32 in the closed position, thereby inhibiting flow through the fluid connector 22.

[0024] According to another aspect of the illustrated embodiment, protrusion 160 may be formed in the rinsing tub 16, and the closure element 32 may include protrusions 154, 156 forming recesses 164 therebetween. Although in... Figure 5 and 6 In the embodiment described herein, the protrusion 160 of the flushing tub 16 is positioned near the edge of the fluid connector 22, but the protrusion may alternatively be spaced apart from the edge. Figure 6 As explained, when the closure element 32 is in the open position, the protrusions 154 and 156 of the closure element 32 are positioned around the protrusion 160 of the flushing tub 16. That is, the protrusion 160 of the flushing tub 16 is positioned within the recess 164 formed between the protrusions 154 and 156 of the closure element 32 to help hold the closure element 32 in the open position relative to the fluid connection 22.

[0025] To enhance engagement of the positioning pawl, one or more biasing elements may be provided. That is, such biasing elements may be provided to facilitate engagement of the protrusion 152 in the closure element 32 abutting the edge of the fluid connection 22 when the closure element 32 is positioned in the closed position, and / or engagement of the protrusion 160 of the flushing tub 16 within the recess 164 formed between the protrusions 154, 156 of the closure element 32. While alternative biasing elements, such as springs, may be provided, in the illustrated embodiment, the biasing elements take the form of one or more ramp surfaces 158, 166. Figure 5 and 6 As seen in the image, the flange 38 on either side of the elongated notch 36 in which the closure element 32 is slidably housed may include a ramp 166. In this way, when the closure element 32 moves from the open position to the closed position, the ramp 166 biases the distal end of the closure element 32 toward the fluid connector 22 via the outer wall 44 of the flushing tank, thereby positioning the protrusion 152 within the fluid connector 22. Figure 5 and 7As shown, protrusion 152 is positioned adjacent to the edge of fluid connector 22 and protrusion 160 of the outer wall 44 of flushing tank to bias closure element 32 into a closed position.

[0026] If it is possible Figures 4 to 6 As seen in the illustration, the closure element 32 may alternatively or additionally include a ramped surface. In the illustrated embodiment, protrusions 154, 156 are positioned along the ramped surface 158 of the closure element 32. Although the ramped surface 158 extends partially across the lateral surface of the closure element 32, it will be understood that the ramped surface 158 may alternatively extend across a larger portion of the lateral surface of the closure element 32. When the closure element 32... Figure 5 The closing position described in the text is advanced to... Figure 6 When in the closed position as described, the protrusion 160 of the outer wall 44 of the flushing tub travels along the inclined surface 158. In this way, with a slight force, the protrusion 154 can be moved above the protrusion 160, thereby allowing the protrusion 160 to be positioned in the recess 164 between the protrusions 154 and 156. It is understood that the protrusion 156 may include the distal inclined surface 168, which may facilitate the initial assembly of the closure element 32 in the elongated recess 36.

[0027] While the illustrated embodiments include multiple protrusions and recesses located in exemplary positions on the closure element 32 and the peripheral wall 44, those skilled in the art will understand that one or more such pawls may alternatively be positioned to define the pawl position. Alternatively or additionally, separate structures may be provided.

[0028] It is also understandable that additional guiding structures can be provided. As an example only, the end of the closure element 32 near the handle or protrusion 40 and the periphery wall 44 of the flushing tub could have a keying structure. Figure 7 In the illustrated embodiment, the closure element 32 has a protruding key 180, and the elongated recess 36 within the outer wall 44 of the rinsing tub may include an elongated groove 182. In this way, the protruding key 180 can slide within the elongated groove 182, thereby guiding the closure element 32 to move within the elongated recess 36. This disclosure contemplates alternative arrangements for guiding the closure element 32 to move within the elongated recess 36. For example, the protruding key 180 and the elongated groove 182 or other guiding structures may be alternatively positioned, and / or the elongated recess 36 may include a protruding key, and the closure element 32 includes an elongated groove for receiving the protruding key. Furthermore, the protruding key 180 may include a spherical structure and the elongated groove 182 and engagement structure, such that the protruding key 180 can slide longitudinally within the elongated groove 182, but prevents lateral movement of the closure element 32 and movement of the closure element 32 at right angles to the elongated groove 182 and the elongated recess 36.

[0029] Those skilled in the art will understand that although at least one closure element 32 is described as a sliding structure, the closure element may have alternative structures. By way of example only, the closure element may be a pivoting element or a rotating element. The closure element may be movable to open the fluid connection 22 to varying degrees to allow, for example, different amounts of flushing fluid within the flushing tank 16.

[0030] According to aspects of this disclosure, the first reservoir 20 may be a sealed chamber, such that the closing element 32 moves to the open position to allow air to enter the first reservoir 20, thereby allowing the rinsing fluid to flow into the rinsing tank 16 through the fluid connector 22. In this manner, the position of the fluid connector 22 within the rinsing tank 16 and the degree to which the closing element 32 is open will determine the level at which the rinsing fluid will rise within the rinsing tank 16. Those skilled in the art will understand that the rinsing fluid will only enter the rinsing tank 16 up to the level at which the fluid connector 22 is open. Therefore, when the fluid connector 22 is held in the open position, clean rinsing fluid will flow into the rinsing tank 16 whenever the level of the rinsing fluid in the rinsing tank 16 falls below the level at which the fluid connector 22 is open. This automatic replenishment of the rinsing fluid within the rinsing tank 16 allows the operator to mop surfaces more quickly and efficiently.

[0031] The rinse tub 16 can have any suitable shape and design. In the illustrated embodiment, the rinse tub 16 includes a peripheral wall 44 extending from the rinse tub base 46. The rinse tub base 46 may include one or more protrusions 48 that enter the interior of the rinse tub 16. The one or more protrusions 48 can serve as a base against which pressure can be applied to the mop head during rinsing. Alternative designs are contemplated in this application. Although not illustrated, but as will be understood by those skilled in the art, the rinse tub 16 may have an actuable drain hole. For example, a recess in a spring-loaded central protrusion (not shown) can be used to open the drain hole in the rinse tub base 46 to allow selective drainage from the rinse tub 16.

[0032] It is understood that the rinsing fluid applied to the mop head in the rinsing tub 16 can be used to clean dust and unwanted substances (collectively, "dust") from the mop head. The outer tub assembly 14 includes an outer tub peripheral wall 50 extending from the outer tub base 52 to form a second reservoir 54 for collecting rinsing fluid and dust from the mop head. To separate excess rinsing fluid containing dust from the mop head, a drain channel 18 is provided for discharging into the second reservoir 54 in the outer tub assembly 14. While the drain channel 18 can be formed by either the inner tub assembly 12 or the outer tub assembly 14, in the illustrated embodiment, the drain channel 18 is formed by a combination of the inner tub assembly 12 and the outer tub assembly 14. That is, the inner tub assembly 12 includes: a first tubular portion 62 of the drain channel 18, wherein the outer tub assembly 14 forms a portion of the bottom surface 64 of the drain channel 18; and a passage 66 between the inner tub assembly 12 and the outer tub assembly 14, thereby allowing discharged fluid to flow to the second reservoir 54. Therefore, the separation of the drainage channel 18 from the outer tank base 52 allows the discharged fluid to flow to the second storage tank 54.

[0033] To facilitate the drainage of fluid from the mop head within the drain channel 18, a wringer assembly 70 may be provided (see also...). Figure 9 While alternative arrangements may be used, in the illustrated embodiment, the wringer assembly 70 includes a rotating element 72 that extends into the drain channel 18 and is configured to rotate a mop head disposed within the drain channel 18. The rotating element 72 defines a central spin axis 74. Although in some designs the rotating element 72 may engage directly with the mop head, a cage or basket 76 may engage with the rotating element 72 and be at least partially disposed within the drain channel 18. In this way, rotation of the rotating element 72 and the basket 76 will rotate the received mop head to expel fluid outward into the drain channel 18 and / or the second reservoir 54.

[0034] To provide selective rotation to the rotating element 72, an actuation assembly 78 may be provided. For example... Figure 3A and 3BAs shown, the rotating element 72 can extend through the outer tub assembly 14 and into the drain passage 18, thereby allowing the actuation assembly 78 to be positioned outside the outer tub assembly 14. The actuation assembly 78 may include a gear assembly 80 and an arm 82, the arm being pivotally mounted to engage the gear assembly 80 and pivotally mounted relative to axis 84. One end of the arm 82 includes teeth 86, while the opposite end of the arm 82 acts as a foot pedal 88 for being depressed by the operator's foot to actuate the gear assembly 80 and rotate the rotating element 72 and the basket 76 (if provided). That is, the arm 82 and the foot pedal 88 are pivotally coupled at axis 84 to a wringer assembly base 89. The wringer assembly base 89 can be coupled to the outer tub assembly 14, with the rotating element 72 extending into the interior of the outer tub assembly 14. A suitable seal may be provided between the rotating element 72 and the outer tub assembly 14.

[0035] If it is possible Figure 8 and 9 As seen in the image, the teeth 86 of arm 82 engage with a pinion 90, which is fixed to gear 92 along axis 94. Gear 92 includes axially oriented teeth 96 that rotatably engage with pinion 98. Pinion 98 is fixed to rotating element 72, such that pressing foot pedal 88 causes rotating element 72 to rotate.

[0036] exist Figure 1 , 2 Exemplary segments of the mop head 100 are illustrated in 3A and 3B. In this exemplary embodiment, the mop shaft (not shown) may be attached to the mop head base 102 at the coupling element 104 or other suitable structure. The fiber mop portion (not shown) may be attached between the mop head base 102 and the retaining element 106. In this embodiment, the mop head 100 has a generally triangular structure and may include, for example, a notch 108 formed by the retaining element 106.

[0037] If it is possible Figure 3A and 3B As seen in the image, the cage or basket 76 may include a basket base 110 having a dome-shaped structure 111 extending into the interior of the basket 76, and the rotating element 72 is received within the dome-shaped structure 111 of the basket base 110. Figure 1 , 2 In the arrangement of the mop head 100 described in 3A and 3B, the dome-shaped structure of the basket base 110 can be at least partially received within the recess 108. In this way, rotation of the basket 76 causes the mop head 100 to rotate.

[0038] Although Figures 1 to 3BEmbodiments 8 and 9 include a wringer assembly 70; however, those skilled in the art will understand that the bucket assembly may alternatively include a cage or basket with an alternative design, or a non-rotating cage or basket. In yet another embodiment, for example, as Figure 11 As described herein, bucket assembly 112 may not include a cage or basket.

[0039] To facilitate the transport of the barrel assembly 10, a handle 114 (see [link]) may be provided. Figure 1 and 2 The illustrated handle 114 can be attached to a pivot point 116 located on either side of the tub assembly 10, which is attached to either side of the outer tub assembly 14. In at least one embodiment, the handle 114 includes a clamp 118 for releasably receiving a shaft or bar (not shown) of the mop. It will be understood that the clamp can have any suitable construction. Reference Figure 8 The clamp 118 may include a bracket 172 for detachably receiving a mop shaft, with fingers 174 disposed around the shaft. The clamp 118 may include a cavity 176 that provides an additional level of flexibility to the bracket 172 and fingers 174. In this way, the clamp can be used with mop shafts of various diameters.

[0040] Furthermore, it can be understood that the inner tank assembly 12 can be separated from the outer tank assembly 14 to facilitate filling the first liquid reservoir 20 and emptying the second liquid reservoir 54. To facilitate emptying the second liquid reservoir 54, the outer tank assembly 14 may include a pouring spout 120. When the inner tank assembly 12 and the outer tank assembly 14 are assembled together, the pouring spout 120 may be spaced apart from the inner tank assembly 12, allowing easy emptying of the second liquid reservoir 54 regardless of whether the assemblies are assembled together.

[0041] To facilitate handling of the inner tub assembly when it is separated from the outer tub assembly 14, the inner tub assembly 12 may include a flange 122 on either side of the inner tub assembly 12, which allows an operator to easily grasp the inner tub assembly 12 for separation from or carrying for filling with the outer tub assembly 14. The inner tub assembly 12 may additionally include one or more legs 124, 126, which, together with the flush tub base 46, may be used to stabilize the inner tub assembly 12 on a surface. In some embodiments, the legs 124, 126 may additionally engage the structure of the outer tub assembly 14.

[0042] The inner barrel assembly 12 and the outer barrel assembly 14 can be formed from any suitable material and by any suitable method. For example, assemblies 12 and 14 can be formed from polymer materials with or without fillers, and can be molded, for example, by injection molding or blow molding. By another example, assemblies 12 and 14 can be 3D printed.

[0043] Furthermore, the inner tub assembly 12 and the outer tub assembly 14 can be formed from single or multiple parts and then assembled by a suitable method. For example, the inner tub assembly may include a first inner tub element 130 and a second inner tub element 132. In this way, the first liquid storage tank 20 may be formed from the first inner tub element 130, the second inner tub element 132, or a combination of the first inner tub element 130 and the second inner tub element 132. In the illustrated embodiment, the first inner tub element 130 includes a rinsing tub 16, while the second inner tub element 132 includes at least a portion of a drain channel 18, and the first liquid storage tank 20 is formed between the first inner tub element 130 and the second inner tub element 132; however, various structures are envisioned under this disclosure. Figure 2 As seen in some embodiments, at least a portion of the first inner tub element 130, here the rinsing tub 16, may be received within and / or through the second inner tub element 132.

[0044] One or more welded joints or other suitable sealing mechanisms may be provided between the first inner tub element 130 and the second inner tub element 132 to provide a sealed first liquid reservoir 20. For example, a first welded joint 134 may be provided around the circumference of the flushing tub 16, a second welded joint 136 may be provided around the circumference of the drain passage 18, and a third welded joint 138 may be provided around the periphery of both the first inner tub element 130 and the second inner tub element 132.

[0045] Industrial applicability

[0046] This disclosure applies to a mop bucket assembly 10, which enhances surface cleaning by providing an immediate supply of rinsing fluid and facilitating effective mopping. A continuous supply of rinsing fluid can be provided to the rinsing bucket 16 by maintaining the closure element 32 in the open position. Since the first reservoir 20 can be sealed in other locations, the level of rinsing fluid in the rinsing bucket 16 will only rise to the level of the fluid connection 22 between the first reservoir 20 and the rinsing bucket 16.

[0047] At least some embodiments of the mop bucket assembly 10 can be easily and economically manufactured, resulting in a reliable and durable mop bucket assembly 10.
