A heat generator includes an electrode terminal, a heating element, an electrically conductive housing, and an insulator. The electrode terminal is stacked on the heating element in a stacking direction. The housing houses a stacked body formed of the heating element and the electrode terminal. The stacked body includes a pair of side wall surfaces each extending in the stacking direction, an element side end surface, and a terminal side end surface. The element side end surface is in close contact with the case inner wall surface. Both the terminal side end surface and the pair of side wall surfaces are entirely in close contact with the case inner wall through the insulator. The housing includes a pair of facing walls facing and extending along the pair of side wall surfaces to serve as a positioning member that restricts the heating element from moving in the intersecting direction.

A heating device includes a base member and a gas burner mounted in or on the base member. An upper housing located above the base member and a tabletop mounted above the upper housing. A hollow heat shield having a proximal end located on or near the base member, and a distal end located within the upper housing, and a support member extending between the base member and the upper housing or tabletop. The distal end of the heat shield extends beyond a proximal end of the upper housing, defining a region of vertical overlap between the heat shield and the upper housing.

A kit for assembling a heating system and a heating system, which when assembled, comprises at least two heating devices, a partition constituting at least a part of one wall of each of the devices, which separates between interiors thereof, and a sealing arrangement mounted at least along upper, lower and rear edges of the partition to at least reduce a heat transfer between the interiors of the two devices at said edges so as to allow individual heating operation of each of the heating devices; the heating devices having a common front wall at least seen from an exterior of the system as a single front face of the system.

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, and an aerosol passage are interconnected.

The heater device has a sheet shaped main body having a heat generating portion heated by energization and a radiating surface for radiating radiant heat toward a heating object by using heat in the heat generating portion, a plate shaped member arranged on an opposite side with respect to the radiating surface of the main body, and an air layer forming member for forming an air layer between the main body and the plate shaped member arranged on a side opposite to the radiating surface of the main body.

An adaptable system for defogging a mirror in a steamy bathroom having a tube assembly with a plurality of openings with an impeller and a plurality of heating elements for blowing hot air through the openings onto the fogged mirror. In one example embodiment, the tube assembly has louvers directing the hot air from the openings. The system has a plurality of mounting assemblies configured for all types of mirrors operative for coupling to the tube assembly, such as a portable mounting assembly with a rechargeable battery that selectively attaches on or adjacent to a mirror. The system has an articulated arm mounting assembly in one example embodiment. The system has a mounting assembly fixture in another example embodiment. A kit comprises the tube assembly and at least one mounting assembly.

A portable heater that includes a ceramic substrate with a heating element configured to define a field of direct radiation, a heat reflector with a concave reflective surface configured to define a field of reflective radiation, a grill cover mounted on the heat reflector, where the ceramic substrate is mounted on an interior side of the grill cover with the heating element facing the concave reflective surface such that the field of direct radiation onto the concave reflective surface is unobstructed.

A cooktop assembly utilizing one or more air flow heaters and one or more associated blowers to superheat air and channel it out a burner (also referred to as a distributor) on the cooktop is described.

Provided is a condensate water trap for a gas furnace that collects and discharges condensate water produced in a heat exchanger and an exhaust pipe. The condensate water trap includes: a first inlet through which the condensate water produced in the heat exchanger is introduced; a second inlet through which the condensate water produced in the exhaust pipe is introduced; a first flow path through which the condensate water coming from the first inlet passes; a second flow path through which the condensate water coming from the second inlet passes; an outlet through which the condensate water introduced through the first and second inlets is discharged; a third flow path into which the residual condensate water passed through at least one of the first and second flow paths but not discharged through the outlet is introduced; and a sensing mechanism that senses if the amount of residual condensate water introduced into the third flow path is greater than or equal to a given amount.

A heater for a vaporizer with air preheating element includes a casing, a tunnel with a perforated bottom, which is a cylindrical heating chamber for placing a cigarette, a heating element of a resistive type, a heat exchanger, including air channels for circulation and preheating of air by a heater, a top end and a bottom end, an air intake hole made in the top end. Outlet holes are communicated with exits of air channels of the heat exchanger for intake of air preheated by the heater in the tunnel. The casing is made in the form of a tape of a thin-film dielectric heat-resistant material, on which a thin layer of resistive material with contacts is applied on the end of one side, forming the heating element, and on the other side a top and bottom spacers are fixed and inclined toward the middle, as well as the edging, which are made of flexible heat-resistant material. The above mentioned tape with a heating element, located on its external side, is rolled into a cylinder and forms a tunnel, and is additionally coiled into several interconnected spiral coils, and forms a spiral casing with the top and bottom ends so that the top and bottom spacers and the edging located on the inside form a spiral heat exchanger comprising the top and bottom and the middle spiral air ducts for spiral and labyrinth circulation and preheating of air, and at the bottom there is an additional inlet hole for air intake.
