  • Patent number: 8752540
    Abstract: A warming oven includes a base, a heating unit, a heat conducting unit, and a reflective shield. The base has an accommodating space. The heating unit is disposed within the accommodating space. The heat conducting unit includes a positioning plate, a top plate spaced apart from the positioning plate, a quartz glass tube inserted into the positioning plate and the top plate, and a plurality of upright connecting rods disposed around the positioning plate and the top plate. The reflective shield is formed with a plurality of vent holes, and includes a bottom cover that covers a top end of the heat conducting unit and that has a vertically curved outer mirror surface for reflecting light from a fire flame produced by the heating unit, thereby providing an illumination effect.

  • Patent number: 8542987
    Abstract: A heater includes a base formed with a receiving space for receiving a fuel material that is to be combusted, and a heating unit. The heating unit includes: a flow guide component disposed on the top side of the base and having a through hole axially aligned and in communication with the opening, and at least one air passage communicated with the through hole and permitting air externally of the flow guide component to flow therethrough into the receiving space via the through hole and the opening; and a heat-radiating pipe disposed to extend upwardly from the flow guide component and disposed to surround the through hole and permitting flow of flue gas resulting from combustion of the fuel material in the receiving space therethrough.

  • Publication number: 20130160756
    Abstract: A two-piece warming oven includes a base, a heat-conducting unit, and a heating unit for heating the conducting member. The base includes a supporting plate, and a plurality of spaced-apart upright supporting rods disposed around the supporting plate and having lower end portions connected fixedly to an outer periphery of the supporting plate to define an accommodating space above the supporting plate and among the supporting rods. The heat-conducting unit is connected removably to the base, and is convertible between a used position, where the heat-conducting unit is disposed above the accommodating space, and a storage position, where the heat-conducting unit is inverted and extends into the accommodating space.
