DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

[0059] The present invention, in some embodiments thereof, relates to portable space heaters and surface heating systems and, more particularly, but not exclusively, to space heaters and surface heating systems adapted for use with infants and young children.

[0060] Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

[0061] According to some example embodiments, the portable space heater includes a number of safety features configured to prevent injury to a person or accidental fires as a result of an infant or young child tampering with the heater. One example safety features includes using a centrifugal fan as opposed to an axial fan to blow the heated air. The centrifugal fan sucks in air from the surrounding and directs the air via a dedicated flow channel along a heating element and out through an air vent (or air outlet).

[0062] An advantage of the centrifugal fan is that its rotating parts are generally enclosed within a housing that the housing with rotating parts may be positioned remote from the air vent and therefore are not easily accessible as a results of tampering.

[0063] According to some example embodiments, the portable space heater includes a proximity sensor configured to sense a body part in proximity to the air vent. A controller of the portable space heater may be configured to pause or shut off operation of the heating element of the heater based on detecting proximity of the body part. Optionally, a fan of the heater may continue to operate without operation of the heating element. Optionally, the proximity sensor is an inductive sensor formed with a coil mounted around the air vent. A change in sensed magnetic field may provide input to the controller that a body part or other object may be close to the air vent.

[0064] In some example embodiments, the portable space heater includes a temperature sensor configured to monitor internal temperature within the heater, e.g. near the heating element. Optionally, the controller is configured to receive input from the temperature sensor and pause or shut off operation of the heating element based on detecting a temperature above a pre-defined temperature, e.g. 75° C. The temperature sensor may prevent overheating of the heating element in situations in which air flow through the air vent may be blocked.

[0065] In some example embodiments, the portable space heater includes an accelerometer configured to detect jolting or toppling of the portable space heater and the controller may be configured to pause or shut off operation of the heating element based on detecting jolting or toppling of the portable space heater. Optionally, the portable space heater may be operated in different orientations, including a horizontal orientation as when positioned on a floor or in a vertical orientation as when hung on a wall.

[0066] According to some example embodiments, the air vent is covered with a grill that is sized to prevent penetration of fingers. According to some example embodiments, the grill includes an array of blades or vanes that that extend inwardly at an angle, e.g. an angle of about 30°-60°, e.g. 45° toward a base of the heater. If a child or other person attempts to insert in object through the grill, the blades will direct the object at the angle and away from the heating element and the centrifugal fan housed in the heater.

[0067] According to some example embodiments, a grill assembly including the grill and a grill holder may be removed from the air vent. The grill holder includes a clasping element (a connector) that is child safe, e.g. a child would not be able to remove the grill holder. Optionally, the grill assembly is configured to be removed from the air vent by an adult and replaced with another connector, e.g. a mat connector configured for use with the surface heating system.

[0068] According to some example embodiments, additional safety features include a metal guard near the heating element and within the heater that is configured to prevent access to the heating element and a protective cover configured to insulate the heating element so that an outer cover of the heater stays cool to the touch.

[0069] Optionally, the heater includes a plurality of operational buttons on a control panel that may be controlled via a touch screen. In some example embodiments, the touch screen includes a child safe locking feature that is configured to automatically lock the control panel during idle periods of the touch screen. Unlocking is configured to be child safe. Optionally, lighting is configured to illuminate through a portion of a translucent cover that covers the control panel. Optionally, the lighting may be used as a night light.

[0070] According to some example embodiments, the surface heating system includes a dedicated mat with one or more air channels that extend through the mat generally parallel to a surface of the mat. In some example embodiments, the mat additional includes a plurality of through going air holes penetrating out through the surface of the mat. During operation of the system, warm air flow received from the heater flows through the air channel(s) and is expelled via the air holes. The flow of warm air is configured to warm the mat as well as warm an area above the mat. The heating is based on conduction as well as convection. The warm air flowing through the air channels may warm the surface of the mat via conduction and the warm air expelled through the air holes and fabric may provide warming via convection.

[0071] In some example embodiments, the mat is formed from a plurality of layers. Optionally, a first layer includes open air channels through which the air from the heater flows in a direction that is generally parallel to a surface of the mat. A second layer overlaying the first layer may include the array of air holes through which air flowing in the air channels is expelled. An optional additional layer may be a fabric material that is overlaid on the second layer. Optionally, the fabric material is configured to scatter the air expelled through the array of air holes. Optionally, the fabric material is three dimensional mesh fabric.

[0072] According to some example embodiments, the number of air channels, size of the air channels, spatial positioning of the air channels, as well as number of air holes, size of the air holes and spatial position of the air holes may be selected to provide uniform heating along the mat, e.g. relatively low temperature gradients across the mat.

[0073] According to some example embodiments, the mat is a playmat and is configured to be child safe. Optionally, the mat is connected to the space heater through an elongated tube through which warm air is delivered. The playmat may be electrically insulated from the portable space heater with non-electrically conducting materials connecting the portable space heater with the playmat, e.g. the elongated tube may be formed from insulating or non-electrically conducting material. Additionally, no electricity, electrical components or electrical wiring runs through the elongated tube between the playmat and the heater. In this manner, a child or infant using the playmat may not be in danger of being electrocuted due to malfunction of the portable space heater. The elongated tube also provides for physically displacing the heater from the playmat and the infant or child on the playmat. Optionally, the playmat is foldable and portable.
