REMOVABLE RESERVOIR WATER DISPENSING SYSTEM THAT MAINTAINS A PRE-SET DISPENSING TEMPERATURE

Abstract

A removable reservoir water dispensing system which includes a water dispenser body with a built-in water reservoir and a coupling for connecting a removable water reservoir to the built-in reservoir. A drainage pipe, through which water is drained from the built-in reservoir, extends through a bottom of the built-in reservoir. The drainage pipe has a first end and a second end. The second end is connected to a dispensing faucet on the water dispenser body. The first end extends vertically into the built-in water reservoir for at least one third of a height of the built-in water reservoir. Water in the built-in water reservoir, positioned below the first end of the drainage pipe, is unable to pass through the drainage pipe to the dispensing faucet and is always resident in the built-in water reservoir at a pre-set dispensing temperature.

Claims

1. A removable reservoir water dispensing system, comprising: a water dispenser body; a built-in water reservoir housed in the water dispenser body, the built-in water reservoir having a bottom and sidewalls; a coupling for connecting a removable water reservoir to the built-in reservoir, such that water is supplied by the removable water reservoir through a water supply inlet to the built-in reservoir; coils which provide heating or cooling encircling the sidewalls of the built-in water reservoir; and a drainage pipe through which water is drained from the built-in reservoir extending through the bottom of the built-in reservoir, the drainage pipe having a first end and a second end, the second end being connected to a dispensing faucet on the water dispenser body, the first end of the drainage pipe extending vertically into the built-in water reservoir for at least one third of a height of the built-in water reservoir, such that water in the built-in water reservoir positioned below the first end of the drainage pipe is unable to pass through the drainage pipe to the dispensing faucet and is always resident in the built-in water reservoir at a pre-set dispensing temperature.

2. The removable reservoir water dispensing system of claim 1, wherein the first end of the drainage pipe extends vertically into the built-in water reservoir for at least one half of the height of the built-in water reservoir.

3. The removable reservoir water dispensing system of claim 2, wherein the water supply inlet from the removable water reservoir terminates in proximity with the bottom of the built-in water reservoir.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] These and other features will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to be in any way limiting, wherein:

[0012] FIG. 1 is a side elevation view in section of removable reservoir water dispensing system.

DETAILED DESCRIPTION

[0013] A removable reservoir water dispensing system generally identified by reference numeral 10, will now be described with reference to FIG. 1.

Structure and Relationship of Parts:

[0014] Referring to FIG. 1, removable reservoir water dispensing system 10 includes a water dispenser body 12 with a built-in water reservoir 14 housed in water dispenser body 12. Built-in water reservoir 14 has a bottom 16 and sidewalls 18. A coupling 20 is provided for connecting a removable water reservoir 100 to built-in reservoir 14, such that water is supplied by removable water reservoir 100 through a water supply inlet 22 to built-in reservoir 14. Coils 24, which provide heating or cooling, encircle sidewalls 18 of built-in water reservoir 14.

[0015] A drainage pipe 26, through which water is drained from built-in reservoir 14, extends through bottom 16 of built-in reservoir 14. Drainage pipe 26 has a first end 28 and a second end 30. Second end 30 is connected to a dispensing faucet 32 on water dispenser body 12. First end 28 extends vertically into built-in water reservoir 14 for at least one third and, preferably at least one half of a height of built-in water reservoir 14.

Operation:

[0016] Referring to FIG. 1, water in built-in water reservoir 14 that is positioned below first end 28 of drainage pipe 26, is unable to pass through drainage pipe 26 to dispensing faucet 32. As a result, such water is always resident in built-in water reservoir 14 at a pre-set dispensing temperature.

[0017] When removable reservoir 100 is empty, water will continue to be dispensed from water dispensing system 10 until the level of water in built-in water reservoir 14 falls below first end 28 of drainage pipe 26. When water is no longer able to enter first end 28 of drainage pipe 26, water dispensing system 10 ceases to function. However, although water dispensing system 10 ceases to function, it is not empty. Water in built-in water reservoir 14, positioned below first end 28 of drainage pipe 26 remains resident in built-in water reservoir 14 at a pre-set dispensing temperature.

[0018] When an empty removable reservoir 100 is replaced with a full removable reservoir, there is already approximately one third, one half or more of the water in built-in water reservoir 14 at the desired dispensing temperature (depending upon where in built-in water reservoir 14 first end 28 of drainage pipe 26 has been located).

[0019] In order to avoid having water received from the removable water reservoir that has not, as yet, reached the desired dispensing temperature passing through first end 28 of drainage pipe 26; it is preferred that water supply inlet 22 from removable water reservoir 100 terminate in proximity with bottom 16 of built-in water reservoir 14. This forces the water newly received from removable water reservoir 100 to migrate up from bottom 16 before reaching first end 28 of drainage pipe 26, giving the newly added water time to cool.

[0020] In this patent document, the word comprising is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article a does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.

[0021] The scope of the claims should not be limited by the illustrated embodiments set forth as examples, but should be given the broadest interpretation consistent with a purposive construction of the claims in view of the description as a whole.
