A thermally insulated cooking pot consists of an outer pot and an inner pot. The inner pot is suspended within the outer pot by hanging from the top inner circumferential area of the outer pot with its own top outer circumferential area. The space between the inner and outer pots becomes an insulation cavity. The contact point between the two pots is sealed by a pliable packing ring with an L-shaped cross-section, thereby sealing the insulation cavity. This sealed insulation cavity provides excellent thermal insulation. The packing ring contains a plurality of protrusions on the surface that come into contact with the inner pot to prevent the packing ring from sticking to the inner pot. The gap formed between the packing ring protrusions and the inner pot prevents the inner pot from sticking to the packing ring.

A method of baking a dessert using steam in an automated household oven comprises a first heating step where a heating system preheats a cooking cavity to a first temperature at a first heating rate and a second heating step where the heating system preheats the cooking cavity from the first temperature to a second temperature at a second heating rate less than the first heating rate. The first temperature is preferably about the boiling point of water, and a steam system introduces steam into the cooking cavity to facilitate baking of the dessert after the cooking cavity reaches the first temperature. A convection fan of the heating system is active during the first and second heating steps to help circulate air and steam in the cooking cavity and becomes inactive later in the baking method.

A thin, flat paperboard inserter or "needle" which is longer than the blood warmer heating plates is attached to the edge of the flattened tube envelope to enter the very narrow gap between the heating plates. The inserter is fed between the heating plates and advanced to emerge from the other end of the blood warmer where it is grasped and used to pull the envelope into operational position. A high air flow hydrophobic vent with check valve to prevent reverse flow is incorporated into the drip chamber to allow automatic priming and venting of air bubbles. A conductively heated and externally insulated drip chamber holder and a patient intravenous line that is passively insulated by a small annular air space extruded as part of the tube preserve heat in the warmed fluid, improving low flow rate performance. A reusable external heater may optionally be applied to the distal portion of the patient line to provide normothermic fluid to the patient down to essentially zero flow rate.

The invention relates to an appliance for cooking under pressure, the appliance comprising:a bowl and a lid; andopening safety means suitable for going between a neutral position, in which they allow the lid to be unlocked, and a blocking position, in which they prevent the lid from being unlocked, said safety means being designed to find themselves in the blocking position when the pressure prevailing inside the vessel is greater than or equal to a predetermined value or “rise pressure”, and / or when the temperature prevailing inside the vessel is greater than or equal to a predetermined value or “rise temperature”;said appliance being further comprising actuating means for actuating the safety means, which actuating means are arranged to make it possible to place the safety means in the blocking position. The invention is applicable to household appliances for cooking under pressure.

The invention provides a fluid heater in which the efficiency of heat transfer to a fluid is improved, downsizing of the heater itself can be achieved, and the rise time until warm water heated to a necessary temperature is supplied is shortened, which results in reduction of the power consumption. The heater includes a flat ceramic substrate (1) and a beating element formed on one surface of or in the interior of the ceramic substrate (1). The ceramic substrate (1) is made of AlN, etc. or silicon nitride, whose thermal conductivity is 50W / m.K or more. A zigzag water channel is formed by walls 6, etc., on the fluid-heating surface of the ceramic substrate (1). A plurality of fins 5 are fixed in the water channel. A heat insulating material 8 can be mounted so as to cover a surface excluding the fluid-heating surface of the ceramic substrate (1).

A steam cooker having a main body, a cavity provided inside the main body, a steam generator provided to generate steam, a supply pipe connecting the steam generator to the cavity to supply steam into the cavity, a discharge pipe arranged to discharge the steam inside the cavity to the outside of the cavity, a discharge nozzle coupled to an end of the discharge pipe, and a cooling fan provided between the cavity and the main body to cool the cavity, and wherein the discharge nozzle is disposed adjacent to the bottom of the cooling fan such that steam discharged through the discharge nozzle is guided downward between the cavity and the main body by the cooling fan. The steam cooker can prevent the condensation water from falling down on the lower part of the main body.
