Description

Sealing Arrangement for Element Plates in Liquid Heating Vessels
Field of the Invention
The present invention relates to a sealing arrangement for element plates in liquid heating vessels.
Background of the Invention
In liquid heating vessels, known as underfloor' heating vessels, a heating element plate forms part or all of the bottom surface of the liquid heating reservoir. The heater itself is attached to or formed on the underside of the element plate, and may be a sheathed, diecast or thick film heater. The applicant's Easifix (RTM) sealing system, as described for example in WO 99/17645, provides a convenient method of sealing and fixing a heating element plate in a liquid heating vessel, such as a kettle. One of the problems addressed by the Easifix (RTM) system is the thermal expansion of a plastics bodied vessel relative to the material from which the element plate is made, such as stainless steel.
One of the solutions provided by the Easifix (RTM) system is to use a form of resilient seal having one or more radially extending fins, which deform to take the shape of the surfaces to be sealed, thus effecting a seal without the need to provide addition compression forces. It is known that the Easifix (RTM) is effective with one radially extending fin however additional fins are provided so that the system has redundancy' against the failure of a single fin.
The Easifix (RTM) system has been very successful, but the applicant is constantly seeking to improve its products.
Statements of the Invention
The present invention provides an element plate seal with one or more radially extending fins, in which one or more radial ribs are provided on the one or more radially extending fins.
The seal may be more tolerant to blemishes and/or an uneven surface on the components to be sealed, for example by increasing the local sealing pressure. The ribs may provide additional redundancy' without significantly increasing, and potentially reducing, the overall size or mass of the seal.
The rib(s) are provided on the sealing surface of the fin(s), the rib(s) may assist in applying an axial force to the fin(s) during insertion of the element plate into the vessel, thereby potentially reducing the insertion force required. In addition, the fins may be angled closer to the element plate than in a conventional Easifix (RTM) seal to further reduce the insertion force required. Alternatively, if two or more fins are provided, the fins may be positioned closer together than in a conventional Easifix (RTM) seal to allow a greater freedom of movement when fitting the element plate because the pivotal points of each fin are closer together.
Brief Description of Drawings
Specific embodiments of the invention will now be described with reference to the accompanying drawings: Figure 1 a is a schematic cross-sectional view of an appliance including a seal in a first embodiment.
Figure lb is a cross-sectional view of a seal of the first embodiment in an uncompressed state.
Figure 2 is a cross-sectional view of a seal in a second embodiment.
Figure 3 is a cross-sectional view of a seal in a third embodiment.
Detailed Description of Embodiments of the Invention In the following description, the upward and downward directions refer to the orientation of a vessel when placed upright on a horizontal surface. Axial refers to the principal, normally substantially vertical axis of the vessel. Radial refers to a direction substantially orthogonal to the axial direction, but does not necessarily imply that the vessel is circular cylindrical.
Similar features between the different embodiments are referred to by the same reference numerals.
Configuration of Vessel Body and Element Plate In each of the embodiments described below, there is provided a heating element plate 3 forming part or all of the floor of a reservoir or heating chamber 2 of a liquid heating vessel.
The sides of the reservoir 2 are formed by a vessel wall 1, which may be made for example from plastics, metal, glass or ceramic material. In preferred embodiments, the vessel wall 1 is generally circular in cross-section about the horizontal plane in the region of the element plate 3, and the element plate 3 is generally circular; in other embodiments, other shapes such as oval may be used.
The diameter of the vessel may decrease with height, so that the element plate 3 must be inserted in the lower opening of the vessel; ahematively the vessel may be parallel sided or the diameter may increase with height, in which case the element plate 3 may be inserted through an upper opening of the vessel. The element plate 3 may be sealed directly against the vessel wall 1, or there may be provided an annular adapter portion between the element plate 3 and the vessel wall 1. The element plate 3 may fit within the vessel wall 1, or extend beyond the vessel wall 1 and seal against an outer surface thereof.
In the embodiments described below, the element plate 3 has rotational symmetry about its central axis, which is generally vertical in use. The element plate 3 comprises a central, generally planar portion and a peripheral flange 4 extending transversely downwards from the central portion and substantially parallel to the vessel wall 1. The lower end portion of the flange 4 may extend radially outwards to form a lip 5.
The element plate 3 is metallic, and preferably of steel such as stainless steel. The central, generally planar portion may include one or more circumferential steps, for example to impart greater strength or to accommodate a particular heating arrangement.
An annular seal 8, of resilient sealing material, is located around the flange 4. The seal 8 include a groove into which the lip 5 fits, and a support wall 10 that extends radially inwardly below the lip 5, thus securing the seal 8 on the flange 4. The seal 8 includes one of more radially extending circumferential fins 11, which form a circumferential seal between the element plate 3 and the vessel body 1.
The underside of the element plate 3 has a heating element thereon; in other words, there is an underfloor heating element. In the specific embodiments, the heating element comprises a sheathed heating element 6 in thermal contact with the element plate 3 via a diffuser 7, but embodiments of the invention are also suitable for use with thick film element plates, where the heating element is deposited as one or more thick film heating tracks on a dielectric layer formed on the underside of the element plate 3.
In each of the embodiments described below, one or more circumferentially extending ribs 12 are formed on the radially extending circumferential fins 11 of the seal 8, where the radially extending circumferential fins 11 comes into sealing contact with the vessel wall I or the element plate 3. The rib(s) 12 preferably extend circumferentially completely around the radially extending circumferential fins 11, so as to provide a secure sealing effect, although a similar effect could be achieved with overlapping circumferential sections, or other variants.
The rib(s) 12 are preferably substantially smaller than the fin(s) 11. In one example, the cross-sectional area of a fin 11 is approximately 5 mm2 and that of a rib 12 is approximately 0.06 mm2; in general, the cross-sectional area of a rib 12 may be between 10 times to 100 times less than that of a fin 11. The size ratio between the fin 11 and the rib 12 can be altered for different application, such that the ribs 12 can compensate for different manufacturing tolerances between the vessel wall 1 and the element plate 3. The cross-sectional profile of a rib 12 may be approximately semicircular or triangular for example.
Preferably, the seal 8 is formed of a substantially homogenous material, for example by a moulding process. Alternatively, the ribs 12 could be formed by a separate process, and fixed to the seal 8 during the moulding process, for example using a twin-shot' process, or after the moulding process. The ribs may be formed of a different material from the remainder of the seal 8; the ribs 12 and the fins 11 could then have different hardness. Alternatively or additionally, the surface of the seal 8 may be treated so as to change the properties of the ribs 12, for example to harden or soften them by, for example, a vulcanisation process.
The seal 8 is preferably fitted around the flange 4 prior to the element plate 3 being fitted within the vessel wall 1.
First Embodiment In a first embodiment, as shown in Figures la and ib, the seal 8 comprises a radially inner lateral wall 9 for abutting the flange 4, and a plurality of (in this case two) axially spaced circumferential fins 11 extending radially outwardly so as to seal against the inner surface of the vessel wall 1, as shown particularly in Figure 1 a.
In the seal configuration of Figure la, the sealing surface of each of the fins 11 comprises a plurality (in this case, three) of circumferential ribs 12, at least some of which contact the vessel wall 1 when the element plate 3 is located within the vessel wall 1. The ribs 12, being smaller than the fins 11, are better able to seal against imperfections in the vessel wall 1.
Figure lb shows a variant of the seal 8 of Figure la, in an uncompressed state. Tn the variant of Figure Tb, there are outwardly facing ribs 12 on the sealing surfaces of the fins 11.
In each of the seals of the first embodiment, the upper end of lateral wall 9 may have a portion that slopes or projects inwardly towards the flange 4, as can be seen in Figure lb, thus providing greater pressure on the upper fin 11.
Second Embodiment In the second embodiment, as shown in Figure 2, only one fin 11 is provided, extending radially outwardly from the lateral wall 9, for sealing against the vessel wall 1. Hence, the second embodiment is substantially a single-finned variant of the first embodiment, which is made more feasible by the presence of the ribs 12. As in the first embodiment, circumferential ribs 12 are provided on the sealing surface of the fin 11. This embodiment is particularly advantageous as the reduction in height of the seal 8 will enable cost savings in the appliance assembly by reducing the material in the seal 8 and may enable a corresponding reduction in material of the element plate 3.
Third Embodiment In the third embodiment, as shown in Figure 3, the seal 8 comprises a radially outer lateral wall 14 for abutting and sealing against the vessel wall 1, and a plurality of (in this case two) axially spaced circumferential fins 11 extending radially inwardly from the lateral wall 14 SO as to seal against the flange 4. An upper extending support wall 13 also projects radially inwardly from the lateral wall 14, and may abut or fit over the flange 4, to provide greater stability.
In the seal configuration of Figure 3, the sealing surfaces of the fins 11 each carry a plurality (in this case three) of circumferential ribs 12, for sealing against the flange 4.
Alternative Embodiments Altemative embodiments of the invention, which may occur to the skilled person on reading the above description, may nevertheless fall within the scope of the inventions as defined by the claims.
