Definitions

  • the present disclosure relates to a heating appliance.
  • Heating appliances are used in many applications for heating items.
  • a cooking hob (or a stovetop) is an appliance that may be used to cook or heat food, liquids, etc.
  • a cooking hob typically includes one or more heating elements that generate localised heat when activated.
  • a pan or other vessel containing food, a liquid, etc. can be placed on an activated heating element in order to cook the food in the pan.
  • the heating element of a cooking hob may be, for example, a gas burner, a radiant heating coil, a halogen lamp, an electrical resistive element or a magnetic induction element.
  • a heating appliance comprising: a heating element; a sensor configured to detect wind impinging on the heating element; a wind shield at least partially surrounding the heating element, the wind shield comprising a wall; a driving element configured to move the wall between a stowed position and a deployed position; and a controller configured to activate the driving element to move the wall from its stowed position to its deployed position if the controller determines the sensor has detected wind impinging on the heating element.
  • the controller allows for the controller to automatically obstruct the flow of wind impinging on a heating element of a heating appliance such as a cooking hob. Impeding the flow of wind in this manner prevents the wind from significantly reducing the effectiveness of the heating element, for example by cooling the heating element and/or by excessive cooling of any cooking vessel (depending on for example the height of the wall(s) once raised).
  • the heating element is a gas burner.
  • the heating element is a gas burner, moving the wall to its deployed position reduces the likelihood that an ignited gas burner will be extinguished by the wind.
  • the heating appliance comprises a plurality of sensors
  • the wind shield comprises a plurality of separately movable walls
  • the sensors being arranged to be capable of determining the direction of wind impinging on the heating element
  • the controller being configured to activate the driving element to move one or more walls according to the direction of wind impinging on the heating element.
  • each sensor being associated with one or more of the walls
  • the controller being configured to activate the driving element to move the one or more walls associated with a particular sensor from their stowed positions to their deployed positions if the controller determines that the particular sensor has detected wind impinging on the heating element.
  • driving element is an electric motor.
  • the or each sensor is located on an uppermost surface of the heating appliance.
  • the or each sensor is located adjacent the heating element.
  • the or each sensor is a temperature sensor.
  • the or each temperature sensor is configured to obtain a measure of the temperature of the heating element.
  • the controller is configured to move the wall from its stowed position to its deployed position if the controller determines that the temperature sensor has detected a decrease in temperature that is greater than a predetermined threshold value.
  • the wind shield fully surrounds the heating element.
  • the heating appliance is a cooking hob.
  • Heating appliances are used in many applications for heating items.
  • a cooking hob (or a stovetop) is an appliance that may be used to cook or heat food, liquids, etc.
  • a cooking hob typically includes one or more heating elements that generate localised heat when activated.
  • a pan or other vessel containing food, a liquid, etc. can be placed on an activated heating element in order to cook the food in the pan.
  • the heating element of a cooking hob may be, for example, a gas burner, a radiant heating coil, a halogen lamp, an electrical resistive element or a magnetic induction element.
  • the environment in which a cooking hob is located can reduce the effectiveness of its heating elements. For example, if the environment is windy then the flow of the wind over the heating element may reduce the temperature of the heating element, thus reducing the temperature of the pan. This is frustrating for a user and is particularly a problem when the heating element is a gas burner because wind can extinguish an ignited gas burner.
  • a heating appliance 1 in this case a cooking appliance, specifically a cooking hob.
  • the heating appliance 1 is a device for use outdoors, such as a barbecue or a grill.
  • the heating appliance 1 includes a heating element 2.
  • the heating element 2 is a gas burner.
  • the heating element may be, for example, a radiant heating coil, a halogen lamp, an electrical resistive element or a magnetic induction element.
  • a plurality of heating elements 2 are provided. Specifically, as is shown particularly in Figure 4, four heating elements 2 are provided in this example.
  • the heating appliance 1 shown in Figure 1 includes two pan supports 3, which are metal grates that provide a surface above the heating element 2 on which a pan can be rested so that the pan can be heated by the heating element 2.
  • pan supports 3 have been removed from the heating appliance 1 in Figures 2 and 3 .
  • the heating appliance 1 also provides for a connection (not shown) to a source of fuel to be used by the heating elements 2 to provide heat.
  • a source of fuel to be used by the heating elements 2 to provide heat.
  • the fuel supplied to the heating appliance 1 is natural gas or a specific hydrocarbon gas or mixture, such as butane and/or propane.
  • the heating elements 2 are radiant heating coils, halogen lamps, electrical resistive elements or magnetic induction elements
  • the fuel may be electricity.
  • the heating appliance 1 also provides for a connection (not shown) to a source of electricity, which is used to ignite the gas and to supply electricity to the other components that are described below.
  • the source of electricity may be a mains connection or may be battery. Indeed, the heating appliance may include a battery.
  • one or more sensors 4 are provided in the region around a heating element 2.
  • the sensors 4 are configured to detect whether wind is impinging on the heating element 2.
  • a plurality of sensors 4 is provided in respect of each heating element 2.
  • the sensors 4 in this example are each located on an uppermost surface 7 of the heating appliance 1 such that when wind is impinging on the heating element 2, wind is also contacting at least one of the sensors 4.
  • the sensors 4 in this example are spaced equidistantly around the heating element 2.
  • the sensors 4 may be configured to also detect one or more of: (i) the speed of the wind impinging on the heating element 2 and (ii) the direction of the wind impinging on the heating element 2.
  • four sensors 4 are provided around each heating element 2.
  • the sensors 4 are adjacent the heating element 2. This arrangement can be used to more precisely detect the direction of wing acting on the heating element 2.
  • three sensors 4 are provided around one heating element 2.
  • Three sensors 4 is the minimum number of sensors 4 that are required to detect the direction of wind contacting the heating element 2 to a reasonable degree of accuracy. More sensors 4 may be provided per heating element 2 for more precisely determining the direction of the wind. Alternatively, fewer sensors 4 may be provided per heating element 2 in order to reduce costs.
  • each of the sensors 4 is a temperature sensor.
  • each of the sensors 4 is another type of sensor that can be configured to detect whether wind is impinging on the heating element 2, such as an anemometer.
  • a temperature sensor can be easily and effectively used to detect the presence of wind because the temperature detected by a temperature sensor will vary depending on whether or not wind is acting on the temperature sensor. If wind is flowing over a temperature sensor then the wind will cool the surface of the temperature sensor and the measured temperature will therefore be lower than when wind is not flowing over the temperature sensor. Accordingly, in this example, if wind is flowing over the uppermost surface 7 of the heating appliance 1 and thus contacting the heating element 2, the wind will cool the temperature sensor and the resulting measured temperature will be lower than when wind is not contacting with the heating element 2.
  • each sensor 4 is in thermal contact with the heating element 2. In another example, each sensor 4 is in direct physical contact with the heating element 2.
  • Each temperature sensor may be, for example, a negative temperature coefficient thermistor or a positive temperature coefficient thermistor.
  • a measure of the speed of the wind can be obtained based on a temperature detected by a temperature sensor because a higher wind speed correlates to a lower measured temperature.
  • a measure of the direction of wind impinging on the heating element 2 can be obtained based on the temperatures detected by the temperature sensors because the temperature sensor(s) that wind is flowing over will detect a lower temperature than other temperature sensors.
  • a wind shield 5 at least partially surrounds the heating element 2.
  • the heating element 2 is fully surrounded by the wind shield 5.
  • the wind shield 5 in this example includes a plurality of walls 6 that are each independently movable between a stowed position (shown in Figure 2 ) and a deployed position (shown in Figure 3 ).
  • each wind shield 5 includes four walls 6.
  • the wind shield 5 may include only one wall 6.
  • the walls 6 each comprise a shape that can impede the flow of wind.
  • each wall 6 has a cuboid shape. When a wall 6 is in its deployed position, the wall 6 protrudes away from heating appliance 1 so that it is raised above the uppermost surface 7.
  • One or more walls 6 may include an indent that receives the pan support 3 when the wall 6 is in its deployed position.
  • the wall 6 is housed within the body of the heating appliance 1 such that an uppermost face of the wall 6 is substantially flush with the uppermost surface 7 of the heating appliance 1.
  • One or more walls 6 may be associated with one or more sensors 4, or vice versa.
  • the heating appliance 1 may include a data storage storing information on the associations between the walls 6 and the sensors 4.
  • a wall 6 may be associated with an adjacent sensor 4. Associating a wall 6 with a sensor 4 allows for that specific wall 6 to be moved between its stowed position and its deployed position based on whether a particular sensor 4 detects wind contacting with the heating element 2.
  • the heating appliance 1 includes an electrical motor.
  • the electrical motor acts as a driving element and is constructed and arranged to drive the walls 6 between their stowed position (see Figure 2 ) and their deployed position (see Figure 3 ).
  • the heating appliance 1 may include a different driving element that can drive the walls 6 between their deployed position and their stowed position, such as one or more hydraulic actuators or one or more pneumatic actuators.
  • the electrical motor can drive each wall 6 individually and independently between its stowed position and its deployed position, for example by use of appropriate gearing and linkages (not shown). This allows for some walls 6 to be driven to their deployed position and some walls 6 to be retained in their stowed position.
  • At least one wall 6 can be left in its stowed position whilst others are in their deployed position, which may make it easier for a user to place a pan on to, or remove a pan from, the heating element 2, whilst the deployed walls 6 still impede the flow of wind impinging on the heating element 2.
  • the heating appliance 1 includes a controller, which may be a processor or the like.
  • the controller is connected to each sensor 4, the electrical motor and the data storage.
  • the controller is configured to move one or more walls 6 from their stowed position to their deployed position when the controller determines that a sensor 4 has detected that wind is impinging on the heating element 2.
  • the controller may be configured to move a wall 6 that is associated with a particular sensor 4 from its stowed position to its deployed position when its associated sensor 4 detects that wind is impinging on the heating element 2.
  • the controller is configured to move one or more walls 6 from their stowed position to their deployed position when the controller determines that a sensor 4, which is a temperature sensor in this example, has detected a change in temperature that is greater than a predetermined threshold value.
  • the heating element 2 of the heating appliance 1 is deactivated and the walls 6 of the wind shield 5 are in their stowed position.
  • a user wanting to use the cooking hob to cook or heat food, etc., activates the heating element 2 so that the heating element 2 outputs heat. Since the heating element 2 in this example is a gas burner, a user turns a dial to begin gas flow to the heating element 2 and then ignites the gas flow using, for example, a match.
  • the heating element 2 is now activated and is outputting heat.
  • a user can now cook food in a pan by placing the pan onto the pan support 3 so that it sits over to the heating element 2.
  • the temperature sensors When there is no wind impinging on the heating element 2, the temperature sensors each detect the same temperature (or substantially similar temperatures) because they are each heated equally by the heating element 2 and not cooled by wind. Consequently, based on the measurements made by the sensors 4, the controller determines that there has not been a change in the temperature detected by a sensor 4 that is greater than a predetermined threshold value. The controller therefore determines that there is no wind contacting the heating element 2 and thus that the walls 6 of the wind shield 5 should remain in their stowed positions.
  • wind begins to contact the heating element 2. If the strength of the wind is sufficient then, since the heating element 2 in this example is a gas burner, the wind may extinguish the ignited gas burner.
  • the wind flows over the uppermost surface 7 of the heating appliance 1, over the sensors 4 and into contact with the heating element 2.
  • the wind may not flow over a sensor 4 if it is hidden behind the heating element 2 because the heating element 2 may impede the flow of the wind.
  • the wind flowing over the sensors 4 reduces the temperature of the surface of at least some of the sensors 4 due to wind chill caused by conduction. This change in temperature is detected by the sensors 4 because the sensors 4 in this example are temperature sensors. The temperature of some of the sensors 4 may be further reduced if the wind is of sufficient strength to blow the flame of the ignited heating element away from these sensors 4.
  • the controller determines that at least one of the sensors 4 has detected a reduction in temperature that is more than a predetermined threshold value. Consequently, the controller determines that wind is impinging on the heating element 2.
  • the controller activates the electrical motor to drive all of the walls 6 of the wind shield 5 from their stowed position (as shown in Figure 2 ) to their deployed position (as shown in Figure 3 ). The electrical motor maintains the walls 6 in their deployed position until the user has deactivated the heating element 2.
  • the walls 6 obstruct the flow of the wind so that the wind does not impinge on the heating element 2.
  • An advantage of this is that by eliminating or reducing the flow rate of wind impinging on the heating element 2, the wind can be prevented from lowering the effectiveness of the heating element 2. Indeed, in this example, the wind shield 5 prevents the wind from extinguishing the ignited gas burner.
  • each wall 6 is associated with a particular sensor 4 (or vice versa)
  • the controller determines that a particular sensor 4 has detected wind impinging on the heating element 2
  • the controller activates the electrical motor to drive the wall (or walls) 6 associated with that sensor 4 from its (their) stowed position(s) to its (their) deployed position(s).
  • the controller activates the electrical motor to drive the wall (or walls) 6 associated with that wind direction from its (their) stowed position(s) to its (their deployed) position(s).
  • the above arrangement therefore automatically impedes the flow of wind impinging on a heating element of a cooking hob. This prevents the wind from significantly reducing the effectiveness of the heating element. Indeed, when the heating element is a gas burner, the arrangement automatically prevents an ignited gas burner from being extinguished by the wind.

  • the chip or chips may comprise circuitry (as well as possibly firmware) for embodying at least one or more of a data processor or processors, a digital signal processor or processors, baseband circuitry and radio frequency circuitry, which are configurable so as to operate in accordance with the exemplary embodiments.
  • the exemplary embodiments may be implemented at least in part by computer software stored in (non-transitory) memory and executable by the processor, or by hardware, or by a combination of tangibly stored software and hardware (and tangibly stored firmware).
  • the invention also extends to computer programs, particularly computer programs on or in a carrier, adapted for putting the invention into practice.
  • the program may be in the form of non-transitory source code, object code, a code intermediate source and object code such as in partially compiled form, or in any other non-transitory form suitable for use in the implementation of processes according to the invention.
