FULLY SEALED WATER DISPENSER MECHANISM

Abstract

A refrigerator water dispenser (10) is disclosed which includes a mounting bracket (11) and a plastic housing (12). The housing houses a water dispensing nozzle (21). The nozzle includes a control valve (22) which is operationally controlled by an electronic switch (23). The housing includes a front panel (27) having a peripheral space (28) which separates the front panel between a peripheral portion (30) and a central portion (31). Hinges (32) allow for the depressed, pivotal movement of the central portion and provides a spring like effect which aids in returning the central portion to its neutral position after it has been manually depressed. A resilient rubber touch pad (34) is coupled to the front side of the housing which includes a peripheral flange (35) that extends into the space of the housing so as to completely seal the entirety of space and therefore the front face of the housing.

DETAILED DESCRIPTION

[0013] With reference next to the drawings, there is shown a water dispenser 10 according to a preferred form of the present invention. The water dispenser 10 is preferably mounted to the interior space of a refrigerator.

[0014] The water dispenser 10 includes a metal mounting bracket 11 and a plastic mount or housing 12 coupled to the mounting bracket 11. The mounting bracket 11 is mounted to the interior of the refrigerator through mounting screws 14. The mounting bracket 11 includes a peripheral series of snap-type mounting flanges 15 and a central opening 16. The top end of the mounting bracket includes a nozzle mount 17.

[0015] The housing 12 is generally rectangular in shape with an enlarged portion 18 at a top end 19. The enlarged portion 18 houses the mounting bracket nozzle mount 17 and a water dispensing nozzle 21 which is coupled to the nozzle mount 17 and in fluid communication with a waterline within the refrigerator. The nozzle 21 includes a control valve 22 which is operationally controlled by an electronic switch 23. The housing 12 has internal beveled flanges 25 which are sized and shaped to releaseably mate with the mounting flanges 15 of the metal mounting bracket 11 in a snap-fit style.

[0016] The housing 12 includes a front panel 27 having a generally rectangular peripheral cut or space 28 which substantially surrounds or encompasses and thereby separates the front panel 27 between a housing stationary, peripheral portion 30 and a housing, movable, central portion 31. The space 28 extends generally about the entire central portion 31. Two C-shaped spring hinges 32 integrally extend between the central portion 31 and peripheral portion 30. The central portion 31 accordingly is integral with the peripheral portion 30 as they are formed of one continuous piece of molded plastic and connected to each other through the hinges 32. The hinges 32 allow for the depressed, pivotal movement of the central portion 31 relative to the peripheral portion 30 as well as providing a spring like effect which aids in returning the central portion 31 to its neutral position after it has been manually depressed to an engaged position and thereafter released. The electronic switch 23 is mounted within the central opening 16 of the mounting bracket 11 closely adjacent the backside of the central portion 31. With this positioning, the central portion 31 engages and thereby activates the electronic switch 23 when the central portion 31 is manually depressed or pivoted inwardly from its neutral position to its engaged position.

[0017] A resilient rubber touch pad 34 is coupled to the front side of the housing 12 about the central portion 31. The touch pad 34 has a peripheral flange 35 that extends into the space 28 of the housing 12 so as to completely seal the entirety of space 28 and therefore the front face of the housing 12. The placement of the elastic, rubber touch pad material within the space also creates a spring or spring like effect which returns or aids in returning the central portion 31 of the housing front panel 27 to its neutral or forward position after it has been manually depressed to its engaged position and thereafter released.

[0018] In use, the manual depression virtually anywhere upon the touch pad 34 causes the central portion 31 to move inwardly and pivot about hinges 32 and into engagement with electronic switch 23. The activation of the electronic switch 23 causes control valve 22 to open and thereby release the flow of water through nozzle 21. Thus, the water dispenser is actuated by a drinking glass, or any object, hitting the touch pad at any location of the touch pad 34 or the front panel, a departure from the prior art dispensers which typically include a select actuation portion which is a small portion of the dispenser's front facing surface. The central portion 31 is returned to its initial position through the biasing force of the hinges 32 and/or the decompression of the resilient material which comprises the touch pad 34.

[0019] As the touch pad seals the opening or space 28 it should be understood that the housing 12, in conjunction with the refrigerator, is sealed so that ambient moisture does not enter the interior of the water dispenser 10. Furthermore, liquids are also prevented from splashing against the drinking glass or ice therein and entering the water dispenser.

[0020] It should be understood that the touch pad may be made of any liquid impermeable, resilient material which provides a spring like biasing force upon compression and subsequent decompression of the pad material.

[0021] It thus is seen that a water dispenser is now provided which overcomes problems associated with the prior art. While this invention has been described in detail with particular references to the preferred embodiments thereof, it should be understood that many modifications, additions and deletions, in addition to those expressly recited, may be made thereto without departure from the spirit and scope of the invention.
