The invention relates to a kettle.

Electric kettles are a well established part of kitchens in Europe and elsewhere and represent an energy efficient way of boiling water for use in making hot drinks and also for cooking purposes, in particular compared to boiling a pan of water on a hob.

The market for kettles has converged on a vessel volume of around 1.51 and come in two main designs, the jug kettle and the classic or dome type kettle. Both types of kettle will have a minimum fill level, which is usually set at 0.51 due to the design constraints of the heating elements. The jug kettle is often filled with water through its spout, located at the upper end of the kettle body, which faces upwards and the both the jug and classic design can be filled through the lid. The classic kettle also generally has an upwards facing spout. These design aspects have been adopted to avoid the risk of boiling water spitting out from the kettle towards the end of the boiling process or when boiled water is being poured.

The known designs suffer from a particular drawback caused by the minimum boil size, which has two adverse consequences. The first is that much water is boiled and not used, which results in significant waste of energy. The second is that for users suffering from arthritis in the hand or arm, the kettle becomes too heavy to use comfortably. Examples of such prior art kettles can be found in GB221832, US2006043124 and WO2012085602. Although the market provides mini-kettles having a small volume, these are of limited utility for many users.

The present invention therefore seeks to provide a kettle that addresses these problems and that in particular is easier for arthritis sufferers to use.

According to the invention there is kettle for boiling liquids comprising a main body, closeable by a lid, a heating element located at the bottom of the interior of the body and a spout, wherein the spout is in fluid connection with the interior of the main body to enable liquids to poured from the kettle, wherein the fluid connection to the interior of the main body is located between the median of the kettle body and the heating element characterised in that there is a second fluid connection between the interior of the kettle body and the spout, which second fluid connection is located between the median of the kettle body and the lid, wherein a baffle is provided, which baffle regulates flow of fluid from the first and the second fluid connections..

Preferably the baffle comprises a tongue adapted to regulate flow from the first fluid connection and an upstand to regulate flow from the second fluid connection. Preferably, the first fluid connection is located in the kettle wall at a height above the heating element. Preferably, the first fluid connection is located substantially at the height of the upper surface of 250ml of liquid in the kettle body. Preferably, the second fluid connection comprises a passage adjacent to the kettle lid and is provided with a holder, which holder is provided with a plurality of apertures, which apertures are provided with a first and second lower edge arrange substantially at right angles to one another. Preferably, the baffle is mounted on the holder.

The kettle according to the invention has a reduced pour angle compared to the known kettles. This enables an arthritis sufferer to pour the boiled water with less strain being placed on the wrist.

An exemplary embodiment of the invention will now be described in greater detail with reference to the drawings in which:

Figure 1 shows a cross section of a kettle comprising a main body assembly 1, a pressure seal assembly unit 2 and a subbase 3. The pressure seal assembly unit 2 comprises a planar element 5, with a circumferential seal 6 as well as the electrical connections 7 to enable electricity to be supplied to the element 5. The kettle is assembled by inserting the pressure seal assembly unit into the jug body so that the planar element 5 forms the base to the water tank of the kettle with the circumferential seal ensuring that the seal is watertight. The element protector and other internal parts are assembled and then the sub base 4 is fitted. The kettle body is closed by a hinged The body of the kettle is provided with a spout 8, which has an opening into the interior of the kettle body at a level a small distance above the heating element 5 to provide fluid communication, eg for water and steam. This opening is below the median of the kettle body, i.e. the distance defined by a plane substantially at the midpoint between the heating element and the lid. The spout extends up the kettle body terminating in an opening through which the water will be poured from the kettle a short distance from the lid 4. The volume provided by the spout therefore forms part of the main interior volume of the kettle so that water in the spout is boiled. By locating the spout cavity entrance near to the base of the main body 1, the pour angle, i.e. the angle to the vertical at which the water can be poured from the kettle, is reduced. This in turn reduces the amount of movement in the users' wrists, which is a cause of arthritic pain. The pour angle of the kettle is reduced by around 15° in contrast to other known designs in the market.

The body of the kettle is provided with a large window 9, the lower extent of which is located close to the element 5, which enables a low minimum volume of about 250ml to be used. This volume equates to about one cup of tea or mug of coffee. This enables users to only boil the required amount of water and again reduces the weight that must be lifted by users with arthritic wrists. As the water level at 250ml is such that water will be in the spout cavity, the pouring action will also be smooth.

A filter assembly is mounted on the kettle body wall extending into the spout cavity. The filter assembly comprises a filter holder 10, filter 11 and baffle 12 described in greater detail below. The filter holder 10 is mounted on the lid and is provided with a plurality of holes which enable steam to escape from the interior to thereby provide some pressure control in the kettle body head room. This reduces the possibility of boiling water spurting out of the kettle during boiling, controls the switch off time and enables water to drain when pouring to the maximum extent when the kettle is at 90° to the horizontal. The holes have a tear drop shape with the lower opening edges being at substantially right angles to one another which significantly reduces the formation of a meniscus, which could otherwise trap a small volume of water. This could lead to spurting on a subsequent boil or cause an early shut off. The filter 11 extends into the spout space and filters any large calcium deposits, common in hard water areas, that may have dislodged into the kettle interior. The filter holder is provided with a seal to prevent any water from entering the lid if the kettle is tilted beyond the horizontal. The filter 11 has a crescent moon shape protruding element, which encourages the water to flow towards the centre of the spout and hence provide a smoother flow.

Figure 2 shows a perspective view from above of the baffle in position with the filter holder and filter removed for clarity. The baffle 12 is provided to prevent spurting during boiling or during pouring immediately after boiling, in particular that which may otherwise occur. The baffle reduces the maximum flow rate from the spout to provide a controlled flow. It also allows steam to escape from the head room from behind the upstand 13. In addition to allowing steam to escape from the head room it also allows water when poured at 90°' so that there is a second fluid communication passage. The upstand 13 prevents the kettle from spurting in over pour (i.e. greater than 90°) as the water is forced into the main flow by flowing around the gaps between the edges of the upstands and the screw mounts located just behind the upstand. There is therefore a passage from behind the upstand 13 into the interior of the kettle. The holes in the filter holder are located spatially separated behind the upstand 13. The tongue 14 stops water spurting from the spout cavity during boiling.
