This disclosure is generally directed to a spray head which can be disassembled for cleaning. In particular, disclosed is a spray head which is designed to dispense heated water over a beverage making substance, for example ground coffee, which is located in a beverage making substance holder or funnel of a beverage maker.
Spray heads are used in beverage making equipment to dispense and distribute water to a beverage making substance. These spray heads are attached to a water delivery line generally in an upper housing portion of the beverage maker. Such spray heads are generally enclosed structures with a threaded mounting portion for threaded attachment to and removal from the water delivery line. A portion of the spray head includes one or more holes through which water is dispensed.
One of the problems with currently available spray heads is that they tend to trap particles carried in the water delivered in the water delivery line. Such particles are difficult to quickly remove from the enclosed spray head. Further, depending on the condition of the water, spray heads tend to accumulate mineral deposits from dissolved minerals carried in the water. It can be time consuming to try to remove such mineral deposits from the inside surface of the enclosed spray heads.
Also, currently available spray heads may not provide for broad dispensing of heated water onto a wide surface area of the beverage making substance. The disclosure provides a spray head which can be removed for cleaning and which can disperse water over a wide surface area of the beverage making substance.
The disclosure provides a spray head for dispersing heated water over a wide surface area of beverage making substance.
The disclosure provides a spray head which is removable from the beverage maker to allow for cleaning.
Briefly, and in accordance with the foregoing, disclosed is a spray head for use with or in combination with a beverage making apparatus. The spray head receives liquid from a liquid dispensing path of the beverage making apparatus and distributes liquid over a beverage making substance retained in close proximity to the spray head. The spray head includes a body portion having a lip extending generally from a periphery of the body portion. A plurality of holes are formed extending through at least the lip portion. A connector is provided for removably attaching the spray head to the beverage making apparatus. The spray head is removable from the beverage making apparatus for facilitating direct contact cleaning of the surfaces of at least the body of the spray head to remove particles and mineral deposits therefrom.
Additional features will become apparent to those skilled in the art upon consideration of the following detailed description of drawings exemplifying the best mode as presently perceived.
The detailed description particularly refers to the accompanying figures in which:
While the present disclosure may be susceptible to embodiment in different forms, there is shown in the drawings, and herein will be described in detail, embodiments with the understanding that the present description is to be considered an exemplification of the principles of the disclosure and is not intended to limit the disclosure to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings.
Terms including beverage and beverage making as used herein are intended to be broadly defined as including but not limited to the brewing of coffee, tea and any other brewed beverage. This broad interpretation is also intended to include, but is not limited to any process of infusing, steeping, reconstituting, diluting, dissolving, saturating or passing a liquid through or otherwise mixing or combining a beverage substance with a liquid such as water without a limitation to the temperature of such liquid unless specified. This broad interpretation is also intended to include, but is not limited to beverage substances such as ground coffee, tea, liquid beverage concentrate, powdered beverage concentrate, freeze dried coffee or other beverage concentrates, to obtain a desired beverage or other food.
With reference to
When the top 16 and bottom 14 are connected using the retainer 18, an interior surface 29 of the top 16 and interior surface 26 of the bottom 14 define a cavity 32 there between. A beverage making apparatus in the form of a brewer 36 of known construction has a water dispensing path 42 in the form of a dispensing tube. Brewer 36 is of known construction such as a beverage brewing device manufactured and sold by Bunn-O-Matic Corporation of Springfield, Ill., assignee of the present application. Such brewers typically include a hot water reservoir which dispenses hot water through a dispensing tube 42 onto beverage brewing substance 56 retained in a funnel 61. The spray head 10 is attached to a hot water dispensing tube 42 and a brewer 36 in the manner as shown in
With reference to
Within the scope of the present disclosure, it is envisioned that one or more tops 16 can be provided with a spray head assembly 10 in which each of the tops has a dimension of extension 86 of the neck 50 which is different. In this regard, a variety of flow rates can be achieved by changing the top 16. Similarly, maximum flow rate can be achieved by placing the top 16 in the condition as shown in
Water flowing into the cavity 32 exits through a series of interior holes 12 and perimeter holes 20. It should be noted that the bottom is formed with a peripheral lip 15 positioned generally at the perimeter of the bottom portion 14. The lip 15 has an arcuate or angled portion 17 which is generally outwardly convex. The perimeter holes 20 are formed in this curved arcuate portion 17. The interior holes 12 are generally formed through a planar or generally flat area 54. The interior holes 12 are located generally spaced around a center 19 of the bottom portion 14 radially internally from the lip 15.
Heated water dispensed through the delivery line 42 flows into the cavity 32 and exits through the holes 12, 20. Water flowing through the holes 12, 20 flows outwardly onto a beverage brewing substance 56. With reference to
The spray head as shown and described in
The generally axially symmetrical configuration of the spray head 10 shown in the figures facilitates easy attachment and removal of the retainer 18. In this regard, the retainer 18 could be formed of an appropriate elastomeric material such as a suitable latex, vinyl, rubber, silicone or any other suitable material. More specifically, the retainer 18 could be ethylene-propylene having 70±5 durometer. Generally, it is desirable to form this material of a generally elastomeric structure so that it can be stretched over the edges 22, 24 to engage the channel 30 with the edges 22, 24. The generally elastic or flexible nature of the retainer 18 allows the gasket structure to be removed from and attached to the top 16 and bottom 14 portions. The elastic characteristics also provide some degree of sealing of the cavity 32 defined between the top 16 and bottom 14.
While a channel 30 is shown it will be appreciated that a continuous band or compressible band which does not have a defined channel could be used and deformed or stretched over the edges 22, 24 to provide the holding or retaining function. It should also be understood that a spring band with an over center latch, a removable adhesive or one or more side mounted chips, as well as any number of other alternatives, fully within the scope of the retaining means disclosed herein could provide this retaining function. Moreover, while the retainer 18 is shown to be positioned around the edges 22, 24, it is envisioned that a suitable retainer 18 could be attached to the top and bottom in a manner which passes over the edges 22, 24 but does not necessarily cover the outer perimeter of the edges 22, 24. In this regard, such a retainer 18 may cross over the faces 80, 82 (see
Generally, the retainer is intended to be broadly interpreted as any device which can hold the top and bottom portions together yet is removable to facilitate disassembly of the top and bottom portions 16, 14. In at least one embodiment the retainer 18 is embodied in a form which facilitates tool-less removal of the retainer 18. It is envisioned that other embodiments may require tools. However, each of these embodiments generally does not require damage or breakage of the connection between the top 16 and bottom 14 to disassemble the spray head. In other words, if the spray head is formed of metal, the assembly would not require severing or otherwise breaking material welds between the top 16 and bottom 14.
It is desirable to be able to remove the retainer 18 or “open” the spray head 10 to facilitate cleaning of the spray head. It is not uncommon for particles or mineral deposits to flow through the dispensing line 42 into the spray head cavity 32. Many such particles or mineral deposits may flow through the holes 12, 20. However, some particles may be too large to flow through these holes and as a result may accumulate in the cavity 32. Additionally, it is not uncommon in a brewing environment for minerals carried in the water to become deposited and/or accumulate in the spray head 10. As a result, it would be desirable to clean the inside of the spray head 10 on a regular basis.
The easy removal of the retainer 18 helps to facilitate regular cleaning of the spray head. In this regard, in order to clean the spray head the retainer 18 is removed from the edges 22, 24. All of the surfaces including the interior surfaces 29, 26 can be cleaned by direct contact by wiping or scrubbing to remove any particles or deposits. Additionally, due to the open draining nature of the spray head 10 as disclosed, these components can be placed in a dishwashing or sanitizing unit to enhance the cleaning and sanitation of the spray head. The spray head 10 can be disassembled and reassembled without the use of any tools or specialized training.
As shown in
The funnel 61 has a mouth 96 through which water is received from the spray head 10 and an outlet 98 though which beverage is dispensed. The spray head 10 has a radial dimension or diameter 100 which is smaller than a diameter 102 the mouth 96 and which is larger than the diameter 104 of the outlet 98. These dimensional relationships help to provide coverage of the beverage making substance with water when making beverage. The outwardly angled flow 106 of water flowing from the holes 20 helps to provide thorough coverage of the substance 56 with water 60.
Additionally, the use of an elastomeric material for the retainer 18 provides a dual purpose of sealing or holding the top portion 16 and bottom portion 14 as well as provided a gripping structure or surface on the spray head 10. It is envisioned that other structures and surfaces can be provided on the spray head 10, for example dimples or gripping recesses are described in embodiments disclosed below. Additionally, the elastomeric or other gripping material can be applied as a coating to an external surface 74 of the spray head 10 to enhance gripping and engagement.
In use, the spray head 10 as disclosed in one embodiment is provided as a single piece body composed of three components including the top 16, bottom 14 and retainer or holding means 18. The spray head 10 can be attached to the dispense line 42 of a brewer 36 by threading the internal threads 52 on the neck 50 into engagement with corresponding threads 84 provided on the corresponding end of the tube 42. The retainer 18 or other structure is provided for gripping the spray head while screwing it into position on the tube 42. A space 70 is provided between the exterior surface 72 of the retainer 18. The space 70 facilitates venting through the vent line 68 into the sump area 34. Heated water dispensed through the dispense line 42 into the spray head enters the spray head and flows into the cavity 32 defined between the top and bottom portions 16, 14. Water in the cavity 32 flows through the holes 12, 20. The pattern formed by the perimeter holes 20 is that generally of a frustum or frusto-conical shape. As such, the spray patter facilitates spraying in the central area (water flowing generally downwardly through the interior holes 12) and the outer areas (water flowing generally outwardly at an angle through the perimeter holes 20) to thoroughly saturate the beverage brewing substance 56 retained in the funnel 61.
In order to clean the spray head, the spray head is gripped and unthreaded from the tube 42 to remove it from the brewer. Once removed, the retainer is disengaged from the edges 22, 24 to disassemble the top 16 from the bottom. For example, one edge 90 defining the channel 30 of the retainer 18 can be flexibly displaced from the top edge 22. This is done by use of finger gripping the edge 90 and peeling or displacing it from the edge 22. Once an initial start has occurred, the remainder of the retainer 18 tends to be removed quite easily. When disassembled, the interior surfaces 29, 26 as well as exterior surfaces of the top 16 and bottom 14 can be manually cleaned or placed in an appropriate dishwashing or sanitation device. In the event that particles or mineral deposits lodge in the holes 12, 20, the generally open structure of the top and bottom portions 16, 14 allow the person cleaning the spray head 10 to use an appropriate instrument to dislodge such particles or deposits.
The spray head 10 as disclosed will not require any tools for attachment or removal relative to the brewer 36 and does not require any tools for disassembly or reassembly. Reassembly generally starts by engaging the edges 22, 24 in the channel 30. Once a portion of the channel 30 has been fitted over the edges 22, 24 the remainder of the channel can be similarly positioned. At some point a substantial portion of the retainer has been positioned over the edges 22, 24 and the remaining portion of the retainer 18 must be stretched slightly to fit over the edges. All of the surfaces and structures can be manually cleaned or automatically cleaned. While a variety of materials can be used, it is envisioned that it is preferable in the disclosed application that a food grade quality approved or certified material will be used as appropriate.
Having described a first embodiment of the spray head 10, additional embodiments will be disclosed. The additional embodiments are based on the same principals a the first embodiment and are within the scope of the present disclosure. In the description of the additional embodiments, reference will generally be made to the same or similar parts or structures using an alphabetic suffix, for example 10“a” to refer the spray head of the second embodiment. It should be understood that the additional embodiments of the spray head are generally interchangeable with the embodiment described above. With this in mind, reference may be made to the brewer 36 and funnel 61 of
With reference to the figures,
Interior holes 12a are located proximate to the center 19a of the body portion 25a allowing heated water to pass generally perpendicularly through the interior holes 12a downwardly onto the beverage making substance. The interior holes 12a are generally radially symmetrical relative to a center 18a of the spray head 10a. The spray head 10a also has perimeter holes 20a located along and formed through the lip portion 15a. Heated water is dispensed through the water delivery line or tube 42a to the spray head 10a. Water flows over an interior surface 26a of the spray head 10a and through the holes 12a, 20a Water flowing through the holes 12a, 20a flows outwardly onto the beverage making substance. Placement of the both the interior holes 12a and the perimeter holes 20a allows dispersion over a greater surface area providing more uniform contact between the heated water with the beverage making substance.
Continuing to reference
Referring again to
When the spray head 10a is engaged with the sump panel 34a, a gap 40 is present between an edge 28 of the lip portion 15a and a surface 31a of the sump panel 34a. As the water level in the spray head 10a rises, water is first dispersed from holes 12a, then from perimeter holes 20a, followed by dispersing from the holes 27. If the heated water level continues to rise above the edge 28 of lip portion 15a, the heated water spills over the edge 28 through the gap 40 and falls on to the surface area of the beverage making substance.
The dimples 22 provide a grip to rotate the spray head 10a to attach it to and disengage it from the tube 42a in the upper housing of the brewer 36. Once the nut 50a is disengaged, the spray head 10a may be removed and cleaned of particles left by water traveling through the spray head 10a and mineral deposits which may otherwise affect flow through the spray head.
