摘要： Disc-shaped planar electric heating elements (1) of the type comprising a stainless steel substrate carrying a resistive track or layer on one side thereof demonstrate a tendency to bow as their temperature changes and this can cause difficulties as regards maintaining proper thermal contact between the heating element (1) and an overtemperature protection control (2) associated with the heating element. To overcome this problem the invention proposes to employ a bracket (3) for mounting the control, the bracket having a plurality of legs (10) fixed to the heating element and two of the legs, which define therebetween a mounting for the control, being fixed to the heating element at positions (11) which are symmetrically disposed on opposite sides of a radius of the disc-shaped element. With this arrangement, if the heating element bows in use, the bracket moves accordingly and maintains the control in thermal contact with the heating element.

摘要： A steam sensor control for an electrically heated water boiling appliance comprises a thermally-responsive actuator in the form of a helix of Titanium-Nickel-Copper alloy shape memory effect (SME) material. The actuator develops a high force and substantial movement as compared with a bimetal and enables a sealed steam sensor control to be achieved wherein the switching contacts of the control are housed within a body part of the control and are isolated from the SME sensor, which is on the outside of the control body part, by a diaphragm seal formed of silicone rubber, the diaphragm seal having an integrally moulded push-rod which on the steam (wet) side of the diaphragm serves as a mounting for the SME helix and on the dry side operates the switching contacts via a bistable trip lever.

摘要： A contact thermostatic switch has a dished, snap-acting bimetallic disc (5) cantilevered from one end of a diameter whereat the edge of the disc is loosely retained between a housing moulding (1) and a metal cap (6) secured to the moulding. At the other end of this diameter, the edge of the bimetallic disc engages a pip (4d) on one end of a lever (4) which is pivotally-mounted in the housing at its other end. When the bimetallic disc (5) snaps to its oppositely dished configuration, it moves the pivotally-mounted lever (4) so as to determine the condition of a set of switch contacts by virtue of the end of the lever (4) which carries the pip (4d) also having depending fingers (4c) which abut a moving-contact carrying leaf spring (2b) of the switch. The cantilevered mounting of the bimetallic disc and its interaction with the lever enables a smaller than conventional disc to be used, with consequent significant cost savings, without prejudicing the operation of the switch.

摘要： A connection system for so-called "cordless" electrical appliances is designed to permit a substantial degree of freedom in the placement of the appliance proper onto the base from which it takes its electrical supply. In a first embodiment (Fig. 1), a plug and socket connector is employed, the plug being coupled to the appliance proper and the socket to the base, and the socket incorporates a pair of pivoting shutter elements which are arranged to be pivoted apart as the plug is inserted into the socket, the plug at the same time unlocking a shutter locking arrangement; this arrangement permits insertion of the plug into the socket throughout almost a full 360 of relative rotation of the plug relative to the socket. A second embodiment (Fig. 7) employs but a single shutter element in the socket part and the shutter is arranged to jam and prevent access to the socket if it is not uniformly depressed; this arrangement permits a full 360 of rotation of the plug relative to the socket.

摘要： An electrical appliance (1) is protected against overheating by the provision of a plurality of series-connected, auto-reset type thermal cut-outs (2) each located in the appliance in the region of a potential hot-spot, and by the provision of a thermal relay comprising a bistable thermally-responsive switch (3) connected in the main power supply line of the appliance and a heater (4) associated with the switch and connected so as to be energized in the event of any of the cut-outs going open circuit. The thermally-responsive switch (3) will thus operate, due to heat generated by the heater (4) and after a certain time delay, in response to any of the cut-outs (2) operating in response to local overheating. The cut-outs (2) can be located at relatively inaccessible regions of the appliance and do not have to be accessed to be manually reset, and the thermally responsive switch (3) can be located in a readily accessible prominent position. This arrangement overcomes the problem of having to have the appliance attended to by a service engineer whenever a cut-out nuisance trips in response to a transient condition, as is the case conventionally when non-auto-reset type cut-outs are employed.

摘要： A thermally-responsive differential expansion device is similar to a bimetallic device but has its plural layers formed of synthetic plastics materials having lower thermal conductivity whereby the device can sustain a greater temperature differential across its thickness (eg. 10 °C) than the negligible differential that a high thermal conductivity bimetal can sustain. Such a 'biplastics' device can be arranged to be insensitive to the constantly rising temperature as water is heated in a kettle since the device will maintain a generally constant temperature differential, but will respond to the onset of boiling when the temperature differential across the device will disappear. Enhanced effects are obtained by use of fibre reinforced plastics materials with the fibres differently oriented in the different layers, so as to take advantage of the dependency of the coefficient of linear expansion upon fibre orientation. Such 'biplastics' devices provide advantages in kettle controls for example since the sensor has only to be mounted on the outside of the kettle wall and need not be exposed to live steam to operate as a boiling control.

摘要： Steam sensor controls in electrical water heating appliances, such as jugs and kettles, operate to switch off the power supply to the heating element of the appliance when water boils in the appliance. The control operates in a wet environment on account of steam condensing on relatively cold parts of the control and this can lead to electrical arcing across wet surfaces of the control. The control is commonly manufactured using moulded plastics material parts (20, 21, 22) and these can be degraded by arcing and give rise to carbon tracks which progressively degrade the electrical insulation properties of the plastics mouldings and can result in failure of the control. To resolve this problem without need for expensive sealing the invention proposes to continue to utilize moulded plastics material for the major component parts (20, 21, 22) of the control, but to insulate electrical terminal parts (23, 24) of the control from each other by means of ceramics material parts (25) incorporated into the control, preferably as push-fit components which engage with appropriately formed apertures in plastics material components of the control. Ceramics materials are generally not susceptible to carbon tracking when wet.
摘要翻译：电水加热设备（如水罐和水壶）中的蒸汽传感器控制功能可在设备中的水沸腾时关闭设备加热元件的电源。由于在控制器的相对较冷的部分进行蒸汽冷凝，控制器在潮湿的环境中运行，这可能导致控制器的湿表面上的电弧。该控制通常使用模制塑料材料部件（20,21,22）制造，并且这些控制可以通过电弧降解并产生逐渐降低塑料模制品的电绝缘性能的碳轨迹，并且可能导致控制失败。为了解决这一问题而不需要昂贵的密封，本发明提出继续将模制塑料材料用于控制的主要部件（20,21,22），而使控制的电气端子部件（23,24）与彼此通过结合到控制器中的陶瓷材料部件（25），优选地作为与该控件的塑料材料部件中适当形成的孔接合的推入配合部件。陶瓷材料通常在潮湿时不易受碳追踪影响。

摘要： An electric immersion heating element has an elongate, metal-sheathed, electrically insulated, resistance heating portion (1) engaged at its ends in bores formed in an element head (2) which may be formed of a synthetic plastics material, a heat transfer element (8) formed of a high thermal conductivity material extends from a heated part of the resistance heating portion adjacent one of its ends through the element head to enable the element temperature to be sensed from the opposite side of the head, and a tubular enclosure (7) extends from the element head (2) and surrounds the said part of the resistance heating portion of the element. The element construction enables dry-boil protection and automatic switch-off on boiling to be achieved by use of a single thermal sensor coupled to the heat transfer element (8) since the steam generated in the enclosure when water boils causes water to be expelled from the enclosure thereby mimicking a dry boil situation.

摘要： An electrically heated water boiling vessel incorporating a planar heating element (2) has an element protector control (9) for switching off the supply of electricity to the heating element (2) in response to a sensed element overtemperature condition and a steam sensor (10) for switching off the heating element (2) in response to the generation of steam when water is boiled in the vessel. The element protector control (9) and the steam sensor (10) are located in a bottom part of the vessel which is compartmentalized so as to segregate the potentially wetted environment of the steam sensor (10) from the element protector control (9) and thereby avoid electrical problems.

摘要： Arrangements for the attachment of element overtemperature protection controls and appliance connector inlet parts to planar electric heating elements are described. The heating element has attachment studs integrally formed on its underside which are designed to be peened over, in the manner of a rivet, to secure a mounting bracket to the element, and the control and the appliance connector inlet part are affixed to the bracket. Redundant studs are provided on the heating element to enable a defective control to be replaced without need to discard the heating element. Mounting brackets which provide compliance in the positioning of the appliance connector inlet part are described, these being advantageous in permitting tolerances encountered in the manufacture of electric water heating vessels to which the subject elements are to be applied to be accommodated.
