Definitions
- the container component in cludes a fixed heating element with an external thermostat sensing projection and a pair of projecting male terminal elements; the lid component includes a handle and pouring spout; and the control component includes a pair of female terminal elements in electrical connection with a power supply cord and mating with the male terminal elements, and a thermostat assembly with a projecting clamp to engage .the thermostat sensing projection.
- the kettle thus provides a componentized assembly wherein any of the components may be readily cleaned or replaced by the user.
- This invention relates to the field of electrically heated containers and, more particularly, to the field of electric kettles.
- This invention is directed toward a kettle construction comprising a plurality of components interrelated by means permitting safe and facil release of the components from each other so that the components may be readily and safely assem' bled and disassembled by the user for cleaning or repair.
- FIG. I is a perspective view of the kettle construction broken away in parts to show the interrelationship of the components
- FIG. 2 is a side elevation view of the lid component crosssectioned in part
- FIG. 3 is a front elevation view of the lid component along lines 3-3 of FIG. 2;
- FIG. 4 is a top view of the container component
- FIG. 5 is a front elevation view of the control component
- FIG. 6 is a side elevation view of the control component.
- FIG. 1 shown a kettle construction comprising a container component generally designated at 1, a lid component generally designated at 2 and a control component generally designated at 3.
- the container component as shown in FIGS. 1 and 4 comprises a pan 4 preferably made of stainless steel and defined by a sidewall 5 and a base 6 with the sidewall having a bead 7 at its top and being substantially vertical from the bead to the base.
- the base has three equiangularly spaced feet 8 of a phenolic composition held to the base by a stud 9 and nut 10 combination, the stud being spot welded to the base.
- the sidewall 5 has a recessed area 11 supporting the heating element 12, preferably made of stainless steel and having a 1500 Watt capacity, by the projection therethrough of a pair of male terminal elements 13, each of which is coaxial with a respective heater element end, and a thermostat sensing element 14 attached to the element center and in thermal contact with it.
- thermostat sensing element 14 includes a threaded bore 43 for purposes to be described hereinafter.
- the sidewall 5 also has a tongue 30 in a plane parallel to the plane of the base 6 and adjacent bead 7, to be described hereinafter.
- the lid component comprises a handle piece 18, preferably made of a phenolic composition and a cover piece 19, preferably made of polypropylene, both being joined by screws 20.
- the cover piece about its periphery comprises a downwardly extending, continuous channel 25 defined by inner and outer flanges 23 and 24 with the outer flange cutaway along the front and rear portions thereof. Within the channel 25 is position an annular gasket 26 adhesively secured thereto.
- the cover piece 19 Adjacent the front portion thereof, the cover piece 19 has a downwardly extending flange 27 abutting flange 24 in part and forming, as seen in FIG. 3, with the cutaway of flange 24 a slot 28 adapted to receive the tongue 30 of the container component.
- the spout area 29 of the cover piece is of conventional construction and may or may not include closure means, pivotable or otherwise.
- a rotatable interrelating or latch means 31 is positioned, the means 31 being rotatively held by screw 32.
- the interrelating means 31, as shown in FIG. 2 includes a finger grip flange 33 projecting downwardly and a bead underlying portion 34.
- the portion 34 in the direction of rotation may or may not include a turned-down corner 34a for purposes of cam-wise facilitating the rotation of the means 31 into the cutaway of flange 23 beneath the bead 7 of the contained, the bead 7 in itself being rounded for camming purposes.
- the flange 33 of the bead underlying portion 34 is intended to contact the periphery of cavity 31a as positioned with respect to the pivot pin 32 so that further rotation after underlying bead positioning is precluded.
- the control component comprises a housing 35, preferably made of phenolic composition and devided into upper and lower chambers 36 and 37 by flange 38, and a thermostat assembly generally designated at 39 and received within lower chamber 37.
- the thermostat assembly is maintained loosely within lower chamber 37 by a pair of screws 45 which are received through the assembly and threaded into respective threaded bores in bosses 46 with shoulders 46a of screws 45 abutting against the front ends of the bosses 46 to permit the loose positioning of the assembly.
- the assembly 39 may move within chamber 37 within the confines of the holes 47, concentric with respective bores 46.
- a screw 42 havinga shoulder 50 which abuts against an internal shoulder 50a on the thermostat assembly extends through the assembly 39 and coaxial thermostat clamp 41 into threaded engagement with bore 43 of the thermostat sensing element 14 on the container component.
- a spring washer 48 is positioned within the cavity 480 to floatingly hold the control component against the container component when the screw 42 is threaded into the bore 43.
- the spring washer is positioned between the base of the cavity 48a and the head of the screw 42 and, because of the resultant floating positioning of the housing 35 with respect to the component 1 and the loose fit of assembly 39 with respect to the housing 35, results in very sensitive thermostatic control.
- Thermostat assembly 39 is, however, held tightly to the container component 1 at element 14.
- the thermostat assembly itself is of conventiona construction and comprises a flexible blade 53 adapted to be contacted by a bimetallic pusher 49, the latter being in thermal contact with the sensing element 14 through clamp 41.
- the flexible blade 53 has a contact 54 which is biased to closed position against a contact 55 on fixed blade 56.
- Assembly of the components is accomplished manually by first inserting tongue 30 of the container component 1 into slot 28 of the lid component 2 and then lowering the channel 25 containing the annular gasket 26 onto bead 7 of the container component.
- the latch means 31 is rotated by the assembler by means of the finger grip flange 33 until the portion 34 clearly underlies the bead 7 or until rotation is stopped.
- insertion of the tongue 30 into the slot 28 is accomplished at an angle so that the following positioning of the bead 7 within the channel 25 provides a compression of the gasket 26. This compression is also accomplished when latch 31 is rotated under the bead 7.
- the corner 34a of latch 31 is preferably turned slightly downwardly so as to provide cam positioning of the portion 34 under the head 7 and facilitate its compressive positioning with respect to the gasket 26.
- control component is positioned with respect to the container component and lid component so that access to the latch means 31 is precluded while the control component is in position,
- the control component female terminals 57 receive the container component male terminals 13 therein and the thermostat clamp 41 clampingly telescopes over the thermostat sensing element 14, and the screw with spring washer 48 in cavity 48a threadedly engages the bore 43 in element 14 to secure the control component 3 to the container component 1.
- the control component includes the leg portion 58 which underlies a portion of the base 6 of the container component to assist in stablizing the floating positioning of the control component.
- the user has access to the container component and heating element and the lid component for cleaning in addi tion to servicing. Also, the requirement of initial disconnection of the control component (before access to the latch means 31 can be had) removes the possibility of contact with a hot heating element when the lid component is removed.
- the tongue 30 and slot 28, the latch means 31 and head 7, the male and female terminals 13 and 57, and the clamp and sensing element 40 and 14 are considered generically to be the interrelating means of the components.
- an electric kettle which not only may be readily repaired by replacement of any damaged or malfunctioning component, but may also be readily cleaned because of the ease of accessibility of the component surface areas to cleaning media.
- the preferred embodiment may be modified within the scope of the present invention as, e.g., by providing a plurality of latch means of the type shown at 31 around the periphery of the lid component to engage under the bead of the container component, by providing the screw 42 with a finger-grip wing-type head so that it would be manually operably without the use of tools along with the other interrelating means et cetera, the preferred embodiment should be viewed as illustrative and not in a limiting sense.
- the preferred embodiment may be modified so that the cover piece and handle piece are two separate components with tha handl piece having the tongue and latch interrelating means to clamplingly hold the cover piece to the container component.
