Heat Accumulator Patents (Class 126/375.1)
  • Patent number: 11141011
    Abstract: A dish assembly for serving food includes a dish housing that defines a surface, upon which the food can be placed, and an inner compartment, a phase-change material within the inner compartment, and an electrically-conductive element inside the inner compartment and thermally coupled to the phase-change material. In a typical implementation, the phase-change material is adapted to melt in response to the electrically-conductive element being heated by an electromagnetic induction heater. The thus heated dish assembly can facilitate getting hot food to a table while it is still hot, and once at the table, keeping that hot food at least warm for quite some time, while it is consumed.

  • Patent number: 8757050
    Abstract: A hot beverage making device includes a boiler for heating water; a housing for accommodating the boiler and connecting element for connecting the boiler to the housing. During operation of the boiler, water is heated and water vapor bubbles are created inside the boiler. Formation of the bubbles causes varying moments about the center of mass of the boiler. The connecting element is adapted to prevent transmittal to the housing of at least a portion of the moment variations. This keeps the noise produced as a result of vibrations of the housing at an acceptable level. In particular, the connecting element is adapted to let the boiler have at least one rotational degree of freedom.

  • Patent number: 8474444
    Abstract: A device for recovering, harnessing and reutilizing heat from along a side wall of a cooking vessel, a cooking vessel comprising such device, and a method of using such device. The device can be constructed as part of the cooking vessel or can be an accessory that attaches to different sized cooking vessels via adjusting means. Specifically, the device is made of a highly conductive and durable metal or metal alloy and comprises a skirt-like body, extending from the side of the cooking vessel and attached to a perforated slip-like portion that may be attached to or integrated into the side wall of the cooking vessel. The device harnesses and reutilizes heat from the underside of the body and safely and efficiently transfers the heat to the cooking vessel through conduction. The device can further comprise diffusers, a bottom portion with a plurality of ventilation openings, and a heat shield.

  • Patent number: 8269155
    Abstract: A heat retaining dish includes a pressure relief mechanism and has a heat retention material capable of being heated by microwave or other thermal radiation in order to maintain any food placed on the dish at an elevated temperature. The heat retention material is capable of accommodating expansion during heating of the device, and when an overpressure condition occurs as a result of inadvertent overheating, the pressure relief mechanism vents the pressure to the ambient environment. The pressure relief mechanism is an integral part of the wall construction of at least one of the portions making up the housing of the device, and deformation due to overpressure directly causes the opening of the pressure relief mechanism as soon as the housing is deformed sufficiently to open a fluid communication path through an aperture in the wall.

  • Patent number: 7980171
    Abstract: A cooking or food warming appliance having a heated heat sink plate situated in a vacuum environment within an outer shell. A food vessel intimately engages the heat sink plate along a food contacting surface thereof by virtue of the vacuum. The vacuum eliminates air gaps between the food contacting surface of the food vessel and the heat sink plate so as to provide instantaneous and uniform heating of the food vessel. The vacuum environment also provides thermal insulation for the heat sink plate whereby heat loss by convection is virtually eliminated.

  • Patent number: 7564010
    Abstract: A jar type cauldron that includes a main body and a lid. The main body is made by shaping and then firing clay, and is constructed so that a bottom wall thereof is thicker than a sidewall thereof. An inner wall is provided in an upper portion of the main body to form a double-wall structure, thus narrowing a mouth provided on the top of the main body and defining a warming space. Further, a central insertion part is provided on the lower surface of the lid, and is inserted into the mouth provided on the top of the main body. A handle is provided in the center of the upper surface of the lid.

  • Patent number: 7150279
    Abstract: A cooking vessel is formed with one or more annular rings rising above a laminate structure that exposes at least one more thermally conductive material of a contrasting color. The raised rings reveal the nature of the thermally conductive material, yet protect it from scratches and abrasion during use, such as when the cooking vessel is resting on a stove top.
