APPARATUS FOR CONTROLLING THE BLENDING OF DRINKS

FIELD OF THE INVENTION

The present invention generally relates to blenders and, more particularly, to apparatus for controlling the blending of drinks.

BACKGROUND

Very popular beverages today are those commonly referred to as “frozen” drinks, whereby a portion of liquid, which may often include a quantity of liquor and/or a flavored drink mix, and a portion of ice may be mixed together in a blending apparatus or blender to create an almost slush-like drink. In the past, the most typical manner to create such drinks may have required an operator to put a quantity of liquor, flavored drink mix, ice, and possibly other ingredients, such as fruit and the like, in the pitcher of a blender, and, thereafter, operate the blender until the frozen drink is perceived to be adequately mixed. The frozen drink may then be transferred from the pitcher of the blender to a patron's glass for consumption.

Such a procedure may have many disadvantages. For example, this procedure, in the sometimes busy environment of some establishments, may require the constant attention of the operator. Instead of operating the blender, the operator could be giving his or her attention to making other drinks while the frozen drink is being prepared.

Moreover, in the above-described manner, a skilled operator may have difficulty making frozen drinks which are consistent in quantity and quality. That is, dependent on the number of drinks to be made, the operator may be required to estimate the proper portions of liquid and ice to mix in the blender. If too small a quantity of liquid and ice are blended, the patron's glass will not be filled on the first try, and the operator will be required to blend additional portions of liquid and ice. Or, as often is the case, the operator may blend too large a quantity of liquid and ice, which, if not eventually used, is wasteful to the economic detriment of the establishment. Furthermore, there is no way to assure that the quality of the drink is consistent from drink-to-drink. If patrons have enjoyed a good first drink, they expect that their second drink will be of the same quality, which cannot always happen when the operator is required to “eyeball” the portion of liquid relative to the portion of ice to be blended.

In typical devices, attempts may be made to control the amount of ice to be delivered to the blending container by operating an ice shaver for a predetermined amount of time. Then, after a predetermined time delay, the blender may operate for a preselected amount of time. However, repeatably consistent drinks cannot be made by such a device in that there is no correlation between the amount of liquid which is manually placed in the container of the blender and the amount of ice to be delivered.

Alternatively, using time as the operative control parameter does not assure that the correct or precise quantity of ice has been added. For example, the ice machine might be almost empty, thereby not having a sufficient quantity of ice for the drink, yet these types of devices would run for a predetermined time and deliver an incorrect quantity of ice. Moreover, even if there was sufficient ice in the machine, it may not always be delivered at a uniform rate and it might not even be delivered at all, as could happen if the ice delivering blades were operating in a dead air space created by an arching of the ice in the machine.

The blending apparatus 10 may include a motor 100 (FIGS. 5 and 7-10). The motor 100 may be of any appropriate shape, size, type or configuration. The motor 100 may be located at any appropriate position on the blending apparatus 10, such as located on the motor mount plate 98, whereby the motor 100 is located within the housing 12. The motor 100 may include an air tube 106.

The air tube 106 may be of any appropriate shape, size, type or configuration, such as of a generally triangular and tubular configuration. The air tube 106 may be located at any appropriate position, such as located on top of the motor 100 (FIGS. 5 and 7-10). For example, the air tube 106 may be located between and engage the motor 100 for cooling air flow purposes to the enclosure 108, whereby air may flow through the enclosure 108, along the S-shaped aperture through the air tube 106 to the motor 100.

The air tube 106 and the enclosure 108 may not be physically secured to one another. For example, the air tube 106 and the enclosure 108 may engage one anther while being physically disconnected from one another. The air tube 106 may be a part of the weighing sensor system, whereby the air tube 106 may be weighed, and the enclosure 108 may be mounted to the rigid structure, which may not be weighed. If the components were physically secured to each other, problems may result in terms of providing an accurate weighing system and reading the load cells.

The blending apparatus 10 may include a holding system for the motor 100 (FIGS. 7 and 8). The holding system may include a thumb screw 92, a slot 102 in the motor mounting plate 98, a pivot point 96 and a pivot bushing 104 (FIGS. 7 and 8). The holding system may provide for the motor 100 to be easily removed from the blending apparatus 10 for ease of service and ease of assembly. Typically, the motor 100 may be connected by grommets. The holding system may provide easy access to set belt tension consistently, which may create a big impact on the life of the motor 100 and its various components.

The thumb screw 92 may be of any appropriate shape, size, type or configuration, such as of a generally circular configuration. The thumb screw 92 may be located at any appropriate position, such as adjacent a side of the drive plate 68 (FIGS. 7 and 8). The slot 102 may be of any appropriate shape, size, type or configuration, such as of a generally oblong configuration. The slot 102 may be located at any appropriate position on the motor mount plate 98, such as adjacent a side of the motor mount plate 98 (FIG. 8). The thumb screw 92 may be rotated or slid out of the slot 102.

The pivot point 96 may be of any appropriate shape, size, type or configuration, such as of a generally cylindrical configuration. The pivot point 96 may be located at any appropriate position on the blending apparatus 10, such as located on and adjacent to a side of the drive plate 68 (FIG. 8). The pivot bushing 104 may be of any appropriate shape, size, type or configuration, such as of a generally cylindrical and tubular configuration. The pivot bushing 104 may be located at any appropriate position on the blending apparatus 10, such as located on and adjacent to a side of the motor mounting plate 98 opposite that of the slot 102 (FIGS. 7 and 8).

The drive plate 68 may also include a retainer 94 (FIG. 8). The retainer 94 may be of any appropriate shape, size, type or configuration, such as of a generally rectangle or square configuration. The retainer 94 may be located at any appropriate position, such as located on the drive plate 68. The retainer 94 may aid in securing the motor mounting plate 98 to the drive plate 68 within the housing 12.

Removal of the drive plate 68 and/or motor 100 may be accomplished by any appropriate means. For example, the drive plate 68 may be removed via fasteners, such as wing nuts or thumb screws, which may or may not require tools for removal. The side panel 22 closest to a tensioning mechanism may be removed in order to provide greater access to the motor 100 in order to access, remove or replace the motor 100.

To remove and/or service the motor 100, the thumb screw 92 may be loosened and tensioning or spring mechanism may be unhooked. The drive plate 68 and motor 100 may then be slid or rotated towards the container housing 70, whereby the thumb screw 92 slides out from the slot 102. On the opposite side of the drive plate 68, as the drive plate 68 is moved towards the container housing 70 and away from the thumb screw 92, the drive plate 68 may also rotate on the pivot point 96 and move away from the retainer 94. The drive plate 68 and motor 100 may then be pulled upwards and away from the base plate 34 for service or removal. To assemble, the pivot bushing 104 may be aligned with the pivot point 96 and the thumb screw may be slid back into the slot 102. The holding system may provide for the motor 100 to be easily removed from the blending apparatus 10 for ease of service, which may provide for consistency of belt tension. Further, the motor may be set to the desired tension using the tensioning system (FIG. 13). The tensioning system may include a spring 91 connected between the motor mount plate 98 and the drive plate 68. The tension of the spring 91 may be adjusted using the tension lever 93. The lever 93 may be rotatable about a pivot point to add or decrease the belt tension. A hard stop 95 may be positioned along the travel path of the lever 93 to prevent over tensioning of the spring 91 and to mark the desired tension point for the system.

The blending apparatus 10 may include an interlock system (FIG. 6A). The interlock system may include an interlock rod 110, a mounting plate 112, a rod magnet 114 and a lid magnet 116 (FIG. 6A). The interlock system may act as a safety feature for the blending apparatus 10, whereby the interlock system may help maintain the lid 60 in a closed and locked position when the blending apparatus 10 is in use. In addition, the interlock system may stop any operations of the blending apparatus 10 when the lid 60 is opened.

The interlock rod 110 may be of any appropriate shape, size, type or configuration, such as of a generally cylindrical and tubular configuration. The interlock rod 110 may be located at any appropriate position on the blending apparatus 10, such as located within a corner of the shaver base 42 (FIG. 6A). The mounting plate 112 may be of any appropriate shape, size, type or configuration, such as of a generally rectangular or square planar configuration. The mounting plate 112 may be located at any appropriate position on the blending apparatus 10, such as adjacent the shaver base 42 (FIG. 8). The mounting plate 112 may secure or mount the interlock rod 110 to the shaver base 42.

The rod magnet 114 may be of any appropriate shape, size, type or configuration, such as of a generally cylindrical configuration. The rod magnet 114 may be located at any appropriate position on the interlock rod 110, such as near an upper end of the rod magnet 114 (FIG. 8). The lid magnet 116 may be of any appropriate shape, size, type or configuration, such as of a generally cylindrical configuration. The lid magnet 116 may be located at any appropriate position on the lid 60, such as within a corner of the lid 60 (FIG. 8). For example, the lid magnet 116 may be aligned with the rod magnet 114.

When the lid 60 is engaged with the ice bin 44, the attraction forces between the magnets 114, 116 may cause the rod 110 to move upwards. The mounting plate 112 may also include a sensor or read switch (not shown) that may be able to determine the position of the rod 110 (i.e. whether the rod is up or down), thereby determining when the lid 60 is attached or detached from the ice bin 44. The blending apparatus 10 may lock out use of selected or all components of the system when the lid 60 is removed from the ice bin 44. The mounting plate 112 may also include a dog leg. The dog leg may act as a stop to prevent the rod 110 from falling out of the shaver base 42, whereby the rod 110 may drop down and stop on the dog leg to stay within the shaver base 42.

The blending apparatus 10 may include a weighing system. The weighing system may include at least one sensor or base plate load cell 38 and at least one sensor and/or shaver base load cell 56. The blending apparatus 10 may include any appropriate number of base plate load cells 38, such as three or more load cells 38 or four load cells 38 (FIG. 8). The load cells 38 may be of any appropriate shape, size, type or configuration. The load cells 38 may be located at any appropriate position on the blending apparatus, such as on each corner of the base plate 34 (FIG. 8). Each base plate load cell 38 may include a cell damper 40 generally located thereon (FIG. 8). The cell dampers 40 may be of any appropriate shape, size, type or configuration. Alternatively, the load cell 38 may be removed and replaced with only a damper 40 (FIG. 17).

The blending apparatus 10 may include any appropriate number of shaver base load cells 56, such as three or more load cells 56 or four load cells 56 (FIG. 6A). The load cells 56 may be of any appropriate shape, size, type or configuration. The load cells 56 may be located at any appropriate position on the blending apparatus, such as on each corner of the shaver base 52 (FIG. 6A). Each shaver base load cell 56 may include a cell damper 58 generally located thereon (FIG. 6A). The cell dampers 58 may be of any appropriate shape, size, type or configuration. Alternatively, the load cell 56 may be removed and replaced with only a damper 58 (FIG. 16).

The blending apparatus may be configured to isolate the ice bin 44 from the drive plate 68 and container housing 70, such that the ice bin 44 may be weighed by the shaver base load cells 56 and the drive plate 68 and container housing 70 may be weighed by the base plate load cells 38. For example, the housing 12, including frame 14 and top frame 16, that supports the ice bin 44 may be arranged to be isolated from the load cells 38. The housing 12 may be supported directly by an outer lip of base plate 34 to distribute the weight of the ice bin 44 directly onto the base plate 34 and through the legs 36, thereby bypassing load cells 38. Accordingly, the base plate load cells 38 may be arranged to weigh only the drive plate 68 and container housing 70. Likewise, the shaver base load cells 56 may be arranged to weigh only the ice bin 44.

The weighing system may utilize any appropriate type of weighing method. For example, the weighing system may utilize an additive weighing method, a subtractive weighing method, or a combination of the two. For example, the drive plate 68 may be weighed by utilizing an additive weighing method. Here, the operator may tare out the weight before dispensing, whereby any ice added may be summed up. The added weight after you tare is how much ice has been dispensed. The load cells 38 may be mounted to the base plate 34 (FIG. 8). When weighing the base plate 34, the load cells 38 may also weigh everything attached to drive plate 68.

In another example, the ice bin 44 may be weighed by utilizing a subtractive weighing method. Here, the operator may tare out the ice bin 44 and then determine any drop or reduction in weight as the ice is dispensed. The load cells 56 may be moutned to the shaver base 52 (FIG. 6A). The weight removed from the ice bin 44 is equal to how much ice has been dispended.

In a further example, the operator may utilize both an additive weighing method and a subtractive weighing method. For example, the load cells 38 may measure the amount of mass added to the container 90 while the load cells 56 may measure the amount of ice dispersed from the ice bin 44. The weights from load cells 38 and 56 may be used as a check to verify measurements. The separate weights may also be used to measure the amount of both ice and another substance added to the container 90 while still measuring the amount of ice dispersed from the ice bin 44.

Utilizing weight to determine the amount of ice needed may permit the operator to make the same drink every time, since the operator is identifying the amount of ice needed by weight. In addition, by allowing the melted water in the ice bin 44 to drain from the ice bin 44 and out from the blending apparatus 10 into the drain cup 80 may further aid the sensors or load cells 38, 56 to accurately measure the ice in the shaver base 42. Alternatively, the cup 80 may be replaced with a tray 81 (FIG. 18). The tray 81 may be larger than the cup to hold a larger volume of drainage and may be connected, such as slidably connected, to the base plate 34 to allow for removal of the tray 81 and disposal of the drainage.

Although the embodiments of the present invention have been illustrated in the accompanying drawings and described in the foregoing detailed description, it is to be understood that the present invention is not to be limited to the embodiments disclosed, but that the invention described herein is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the claims hereafter.
