1. Field of the Invention
The present disclosure relates generally to a device for emitting bubbles as may be used in a vehicle wash system. More particularly, the present disclosure relates a device for a vehicle wash system that emits bubbles in a fashion that they can be forcibly transmitted or propelled to a vehicle exterior or other component.
2. Description of the Prior Art
Soap and foam are widely used in vehicle wash facilities. Recently bubblers or bubble arches have been introduced for coating a portion of a vehicle exterior with bubbles. Current bubbling arches operate such that the “bubbles” are formed then conveyed to the vehicle exterior solely based on gravitational forces. These bubbling arches have limitations, including an inability to uniformly distribute the “bubbles” across the exterior surface of the vehicle. As such, the soap that is part of the foam may not contact the entire exterior surface of the vehicle to be treated. This can result in the vehicle exterior not being sufficiently cleaned as well as the perception in the mind of the vehicle operator that the vehicle exterior is not being sufficiently cleaned.
Also, while these current devices are self-referred to as bubblers, they really only generate foam, which is a fluid consisting of very small bubbles. The generation of these very small bubbles or foam requires the utilization of a large amount of chemical, which can be very expensive. Additionally, the foam generated by these devices has a very heavy appearance and is thus not aesthetically attractive.
It would therefore be desirable to provide a device that emits bubbles, such as for use in a vehicle wash process that overcomes the disadvantages and limitations that exist with these current devices.
It is therefore an aspect of the present disclosure to provide a device that emits bubbles onto another surface that overcomes the above disadvantages.
It is a related aspect of the present disclosure to provide a device for use in a vehicle wash system that emits bubbles onto an exterior surface of a vehicle such that the bubbles contact a greater portion of the vehicle exterior.
It is another aspect of the present disclosure to provide a device that can forcefully emit bubbles therefrom so they can be projected onto a desired surface.
It is a related aspect of the present disclosure to provide a device that is configured to forcefully emit bubbles onto a top and/or side exterior surface of a vehicle.
It is another related aspect of the present disclosure to provide a device that is configured to forcefully emit bubbles onto another component of a vehicle wash system, such as a rotary brush, so the bubbles can be applied to an exterior surface of a vehicle by the media elements of the brush.
It is a further aspect of the present disclosure to provide a device that is configured to emit bubbles in a fashion that can uniformly cover an exterior surface of a vehicle.
It is yet another aspect of the present disclosure to provide a device that can be configured to emit bubbles onto vertical surfaces of a vehicle exterior, such as side surfaces or wheels.
It is yet a further aspect of the present disclosure to provide a device for emitting bubbles that utilizes fewer chemicals and therefore decreases the costs associated with prior devices.
It is still yet a further aspect of the present disclosure to provide a method for manufacturing a bubbling device.
In accordance with the above and the other aspects of the present disclosure, a device for emitting bubbles for application to a structure in vehicle wash system is provided. The device includes a plenum supported with respect to ground. The plenum includes an air inlet having a first area and an air outlet having a second area. The plenum is in communication with a foaming chamber. The foaming chamber includes an aerating media element disposed therein. A fluid dispensing mechanism is disposed in the foaming chamber and in communication with a source of chemical. The fluid dispensing mechanism is configured to emit a chemical onto the aerating media element. The foaming chamber is in communication with a plurality of outlet elements in the fluid dispensing mechanism for emitting bubbles therefrom.

According to an aspect and as shown in the FIGs, the device 10 can be configured to be disposed adjacent a vehicle treatment area in a vehicle wash facility. According to one aspect, the device 10 may be configured as an arch to emit bubbles onto a vehicle from a location above the vehicle. According to a further aspect, the device 10 may be configured to emit bubbles onto a vehicle from a location beside the vehicle. According to another aspect, this allows the device 10 may be configured to emit bubbles onto side surfaces of a vehicle and/or wheels. The device 10 can be used in any type of vehicle wash process, such as a tunnel wash or a roll-over wash. If employed in a vehicle wash facility, the device 10 can be utilized at the front end of process. Alternatively, the device 10 may be utilized a majority of the way down the wash facility in the buff and polish area to emit an extra service wax onto the vehicle. It will be appreciated that the device 10 may be utilized virtually anywhere in a vehicle wash process as desired.
In accordance with an aspect, the device 10 includes a support structure that contacts ground and serves to support the device. As shown in this example, the support structure may consist of a pair of legs 20 with each leg disposed on either side of the vehicle treatment area. According to another aspect, the device 10 may be disposed on one side of a vehicle treatment area. With this configuration, the support structure may consist of a base. It will be appreciated that the support structure can have a variety of different configurations. As shown, the device 10 can include a plenum 22 that may be oriented generally parallel to the ground. According to an aspect, the plenum 22 may have a first end 24 that is supported by one leg 20 and a second end 26 that is supported by another leg 20. The device 10 can be formed of a plastic material via a conventional plastic injection molding process. However, it will be appreciated that the device 10 may also be formed from a variety of other suitable materials and can be formed from a variety of other suitable processes.
According to a further aspect, the plenum 22 may be formed by a rotational molding technique. According to yet another aspect, the plenum 22 may be formed by a blow molding process. With reference to
According to one aspect, the plenum 22 can include an air inlet 28 located at the first end 24 that allows air to be drawn into the plenum 22. It will be appreciated that the air inlet 28 can be located at either end 24, 26 of the plenum 22. Additionally, the air inlet 28 may be located in a variety of other locations along the plenum 22 besides the ends. According to another aspect, the plenum 22 could include more than one air inlet opening.
According to an aspect, the plenum 22 can be configured to allow the airflow through the air inlet 28 to be varied. According to still another aspect, the plenum 22 can include an air regulator mechanism 30 that allows the air that flows through the air inlet 28 and into the plenum 22 to be controlled or varied by an operator. It will also be appreciated that the air flow rate may be varied automatically under computer control. According to an aspect, a blower or fan 32 may be disposed adjacent the air inlet 28 to draw air into the plenum 22, as best shown in
According to one aspect, the air regulator mechanism 30 may consist of a control module that allows the RPMS of the blower 32 to be controlled or adjusted to vary its speed and thus the airflow into the air inlet opening 28 and thus into the foaming chamber 70, as is discussed in more detail below. According to still another aspect, the air regulator mechanism 30 may consist of a vent 36 located remotely from the inlet opening 28. As shown in
According to an aspect, as best shown in
In operation, the blower 32 may be configured to draw air into the plenum 22 through the plurality of openings 40 and 48 on the fixed plate 42 and the rotatable disk 46 respectively. According to an aspect, the rotatable disk 46 may be moved such that the openings 48 in the rotatable plate 46 are no longer completely aligned with the openings 44 in the fixed plate 42. By this configuration, the surface of the rotatable disk 46 can block some of the area of the openings 44 in the fixed plate 42 so that less area exists for the air to be drawn into the plenum 22. According to an aspect, the air regulator mechanism 30 may thus be configured to change to effective size of the inlet openings to vary the amount of air that is drawn into the plenum 22 as a result of the blower 32 as well as its velocity. It will be appreciated that the air regulator mechanism 30 can take on a variety of different configurations. According to an aspect, the blower may also include a motor 90 and an impeller 92 for drawing air into the plenum 22. As also shown, once the rotatable disk 46 is in its desired position with the openings sized to properly tune the airflow in the device 10, a plurality of knobs 94 can be tightened to secure the rotatable disk 46 in place. It will also be appreciated that a variety of other suitable mechanism may be employed to draw or force air into the plenum 22.
According to an aspect, the device 10 includes a plurality of nozzles portions 50 for emitting bubbles from the device. Each of the plurality of nozzle portions 50 may be secured adjacent an outlet opening 52 formed in a surface of the plenum 22. Each of the nozzle portions 50 can include an inlet end 54 that is configured to communicate with a respective outlet opening 52 and to secure the nozzle portion to the plenum 22. According to an aspect, the nozzle portions 50 may be attached to the plenum 22 by a bayonet mounting connection 56. As shown, the inlet end 54 of the nozzle portion 50 can include a plurality of bayonet projections 56 disposed therearound that are configured to pass through slots 58 formed in the outlet opening 52. As will be appreciated, the bayonet projections 56 can be aligned with the slots 58 such that they can pass therethrough. Once the bayonet projections 56 have passed through the slots 58, they can engage a channel or other guide structure in the plenum 22. The nozzle portions 50 can then be rotated such that the bayonet projections 56 are no longer aligned with the slots 58 and the nozzle portion 50 is secured to the plenum 22. This allows for a quick attachment and detachment of the nozzle portion 50 from the plenum 22. According to another aspect, the nozzle portion 50 can be attached and detached from the plenum 22 without having to shut down the vehicle wash system. It will be appreciated that the nozzle portions can utilize a variety of different attachment mechanism to secure the nozzle portions thereto, such as via threaded connection. An O-ring, gasket, or other sealing mechanism 68 may be employed at the connection of the nozzle portion 50 to the plenum 22.
According to another aspect, each of the nozzle portions 50 can include an outlet end 60 with a plurality of spray nozzles 62 formed therein. As shown, the plenum 22 may include six nozzle portions 50 with each nozzle portion including three spray nozzles 62. It will be appreciated that the number of nozzle portions secured to the plenum 22 may vary. It will also be appreciated that the number of spray nozzles 62 formed in each nozzle portion 50 may also vary as desired. According to an aspect, the number of spray nozzles 62 may be greater than the number of outlet openings 52 to assist in the acceleration of air though the device 10, as is described in more detail below.
According to a still further aspect, the nozzle portions 50 may be formed from a rotational molding technique. Alternatively, the nozzle portions 50 could be formed from a blow molding process. It will be appreciated that other suitable forming or molding processes could be employed. With reference to
According to another aspect, each nozzle portion 50 can include a foaming chamber 70. It will be appreciated that in the illustrated embodiment, the device 10 can include six separate foaming chambers; one for each nozzle portion. Pursuant to this aspect, each foaming chamber 70 can include a media element 72 or a filter. According to a further aspect, the media element 72 may be an aerating structure, which allows for a high volume of low pressure air to pass therethrough for the formation of bubbles, as is discussed in more detail below. It will also be appreciated that the media element 72 may be constructed as a two dimensional or planer media. An exemplary media element can consist of a fine mesh screen. However, a variety of other suitable materials may be employed for the media elements 72.
According to a still further aspect, a spray jet 74 may be disposed in each foaming chamber 70 to allow a supply of chemical to be delivered thereto. According to an aspect, the chemical may be soapy water. However, a variety of other suitable chemicals may be employed. The spray jet 74 can be configured so that the chemical is directed onto the media element 72. According to an aspect, the media element 72 may be configured such that it is disposed across the entire area of the foaming chamber 70 such that air that flows therethrough must pass through the media element 72. As shown, the spray jet 74 may be configured such that direction of spray emitted therefrom can be generally parallel to the flow of air. Each of the spray jets 74 may be preferably oriented in each foaming chamber 70 such that it is oriented perpendicular to the media element 72. Put another way, the spray jet 74 may be oriented so that it is parallel to the air flow into the foaming chamber 70 such that the fluid emitted from the spray jet 74 may be efficiently disposed onto the media element 72. Each of the spray jets 74 may be in communication with a source of chemical such as through hose connection or the like. Each spray jet 74 may be oriented in a variety of different ways and may also receive chemicals in a variety of suitable fashions.
In operation, air can be drawn into the plenum 22 through the inlet opening 28 via the blower 32. The rate at which the air flows through the device 10 into the foaming chamber 70 can be controlled by the air regulator mechanism 30. The air in the plenum 22 may then be fed through each of the outlet openings 52 into each of the individual foaming chambers 70. In the foaming chamber 70, the air may then encounter the media element 72 and interact with the chemical solution thereon to form bubbles as the air passes through the media element 72. According to an aspect, the created bubbles may then be passed to each of the spray orifices 62 such that they may be emitted for use, such as for application onto an exterior surface of a vehicle. The speed of the air as it contacts the media element 72 will directly affect the size of the bubbles. According to an aspect, low pressure, high velocity air is employed as opposed to the pressurized air employed by prior foaming devices, the bubble size can be more readily controlled and may be smaller so as to require less chemical use. This provides a significant cost benefit as well as more aesthetically appealing bubbles.
According to an aspect, the plenum 22 and the nozzle portions 50 may be configured such that the bubbles are emitted from the spray nozzles 62 at a velocity in order to propel them onto the exterior surface 12 of the vehicle 14. In other words, the bubbles emitted from the spray nozzles 62 are emitted with enough force that the bubbles can be projected sideways, such as onto a side surface of a vehicle or vehicle wheels. This is a significant advantage over prior foam generation devices where the foam is emitted from the device and conveyed to the surface of a vehicle under the force of gravity only.
According to an aspect, the force to emit the bubbles onto the vehicles may come from the tapered relationship of the various components of the device 10. More specifically, the tapered relationship of the size of the inlet end 54 to the size of the orifice of the spray nozzles 62 assists in accelerating the air through the device without the need to utilize a source of pressurized air. According to another aspect, each of the nozzle portions 50 is designed such that it tapers geometrically and mathematically. Geometrically, the taper may result from a narrowing of the passage through which the fluid travels and it passes through the nozzle as shown in
As shown best in
Additionally, the area of each of the spray nozzle 62 is smaller than the area of the foaming chamber 70. According to a further aspect, an outlet passage 82 connects the lower chamber 76 to each spray nozzle 62. As can be seen in
With reference to
In operation, the blower 32 draws air into the plenum 22 and forces it to the nozzle portions 50 and into the individual foaming chamber 70. The air regulator mechanism 30 allows the rate of airflow brought into the foaming chamber 70 to be regulated. This provides a tunability of air flow, which allows the consistency of the bubbles emitted from the device to be controlled. According to an aspect, this variability in air flow allows for the use of different chemicals to be employed with the device 10. According to an aspect, the device 10 can emit bubbles or streams of bubbles as opposed to foam, which is what is emitted from prior devices. As will be appreciated, bubbles use less chemical and thus are advantageous as compared to foam that requires more chemical and is thus more expensive.
According to a further aspect, the bubbles emitted from the device 10 may have an aesthetically pleasing quality. As will be appreciated because of the two dimensional aerating media element, the air interacting with the chemical thereon can create bubbles similar to conventional children's bubble makers. The bubbles may be relatively large such that they appear transparent. This is in contrast to the foam generated by other conventional devices where, to the extent any bubbles exist, they are very small and provide a different appearance.
According to still another aspect of the disclosure as exemplarily shown in
As shown, according to an aspect, the component 104 is configured with a plurality of self-supporting media elements 106 and a hub 108 that is designed to rotate at a lower RPM in order to provide a more pleasurable vehicle wash experience, such as disclosed in Applicant's co-pending U.S. patent application Ser. No. 13/668,058, entitled “An Improved Vehicle Wash Component”, which was filed on Nov. 2, 2012, the disclosure of which is hereby incorporated by reference as though set forth fully herein.
According to this aspect, the device 100 can propel bubbles to a location adjacent the hub 108. Also, according to another aspect, the bubbles emitted from the device 100 have demonstrated a tendency to cling, whether to the media elements or to a vehicle exterior. This can provide the ability to coat the media elements with bubbles such that they can be transmitted to the vehicle exterior. Additionally, the slow rotation of the component 104 ensures that the bubbles will not be “popped” or thrown off of the media elements before they can be applied to the vehicle exterior.
According to still a further aspect, one or more light sources, such an LED light strip may be associated with the device adjacent the nozzles 102 such that bubbles may be illuminated with different colors as they are emitted from the nozzles. It will be appreciated that a variety of different light sources may be employed and which may be disposed in various locations to light up the bubbles. It will also be appreciated that the lights may be of different colors and that the light sources may be operated under computer control to vary the color at different points, to blink or flash at predetermined points or to accomplish various other functions to enhance a user's vehicle wash experience. Additionally, one or more light sources could be associated with the vehicle wash component.
According to yet a further aspect, a variety of different chemical products may be connected to the spray jets so that bubbles comprised of different chemicals may be transmitted to the foaming chamber before being emitted onto the vehicle exterior. For example, waxes may be utilized. Additionally, incompatible chemicals could be passed through the nozzles and caused to mix on the vehicle surface, such as some specialty waxes.
According to still yet another aspect of the present disclosure, a method of applying bubbles to a vehicle exterior as part of a vehicle wash process is provided. According to this aspect, a device for creating bubbles may be disposed adjacent a vehicle treatment area of a vehicle wash facility. The device may have a variety of different configurations, however, according to an aspect, the device may be configured as set forth herein. As exemplarily shown in
According to an aspect, the vehicle treatment component can be configured to rotate at low RPMs in order to apply the bubbles resident on its media elements to a vehicle exterior. Application of bubbles to a vehicle exterior is a desirable feature as bubbles on the vehicle wash component can provide an impression of cleanliness, particularly knowing that the bubbles will be applied to the vehicle exterior. Because the vehicle wash component may be rotating at a low RPM, the application of the bubbles can occur in a paint friendly manner. According to an aspect, because of the slow rotation of the component, as the vehicle wash component contacts the vehicle, the bubbles will transfer from the media elements to the vehicle exterior.
According to a further aspect, the application of the bubbles to a vehicle as part of a vehicle wash process can be an option selected by a customer that may be obtained come as an additional charge (“the bubble treatment”). If a customer elects this feature, a device for emitting bubbles can be activated, such as by computer control. According to this aspect, the device will generate bubbles and apply them to one or more vehicle wash components. The bubbles can fully cover the media elements of the component and adhere thereto as the vehicle wash component is rotating. According to an aspect, the vehicle wash component is rotating slower and can apply the bubbles to the vehicles exterior that has been selected for this treatment. According to a still further aspect, lights may be employed to illuminate the bubbles and/or the vehicle wash components as part of the selection of the bubble treatment.
According to a still further aspect, if the next vehicle in line has elected not to have the bubble treatment, a controller associated with the device can be configured to prevent bubbles from being applied to the vehicle exterior. According to one aspect, a fluid can be applied to the vehicle wash component to eliminate the bubbles. The fluid may be a de-foaming agent. Alternatively, other fluids such as water may be applied to the vehicle wash component to eliminate the bubbles. It will be appreciated that a variety of other suitable fluids or devices for removing the bubbles may be employed. Additionally, other mechanism may be employed to remove the bubbles, including utilizing a vacuum to pull off any bubbles that may exist on the vehicle wash component. Other suitable mechanism and methods may be employed. According to this aspect, the same vehicle components can be utilized to provide different options to customers and thus the possibility of generating additional revenues for vehicle wash owners.
