Description

The invention relates to a kettle with a cooking container, a coffee machine with such a kettle and a soup machine having such a kettle. More particularly, it relates to a coffee machine, a soup machine and an induction kettle in which the heat efficiency is increased by double-sidedly using the induction current plate, and in addition to a homogeneous mixture, foaming is also promoted by moving the plate.

Heating by a metal plate with induction current may take less time and have higher heat efficiency compared to other heating methods. Electric induction boilers are being used more and more in industry and households because the plates with induction current are more efficient compared to conventional kettles and the heat output is stopped immediately in the event of energy interruption. In addition, when heated or boiled with induction current, there are no risks such as spontaneous combustion or explosions.

The containers for ingredients such as water, sugar and coffee for the preparation of Turkish coffee and other drinks are heated from the bottom in conventional kettles. However, the heat transfer can not be stopped immediately upon reaching the desired temperature, even if the power source is turned off. The heat transfer to the cooking container continues because of the thermal inertia of the device, even if the power source to interrupt the heat transfer is turned off immediately.

The water heater ( 10 ) according to the invention comprises a cooking container ( 1 ) in which the food to be cooked and / or to be heated is placed, a first floor ( 6 ), the bottom of the cooking container ( 1 ), at least one heating plate ( 2 ), which is positioned very close to this ground, a motor ( 4 ), this heating plate ( 2 ), preferably rotates, and a lower part ( 8th ) under the cooking container ( 1 ), preferably the engine ( 4 ), the sink ( 3 ) and other system elements surrounds.

The aim is to use the kettle ( 10 ) according to the invention, both sides of the heating plate ( 2 ) to use efficiently and thus to increase the energy efficiency and to allow the liquid in the cooking container ( 1 ) by geometric shapes on the top ( 31 ) and underside ( 32 ) of the heating plate ( 2 ) is stirred better. In addition, the flaps ( 21 ) on both sides (top and bottom) of the heating plate ( 2 ) the increase of the active area. As in 1 illustrated, the first floor ( 6 ), the bottom of the cooking container ( 1 ) made of a non-metallic material, usually a hole in the middle, through which a shaft ( 5 ), which drives the engine ( 4 ) on the heating plate ( 2 ) transmits. The hole through which this wave ( 5 ) is sealed with a gasket or similar suitable filler. As well as in 1 represented, is the engine ( 4 ) under the first floor ( 6 ) in the lower part ( 8th ) connected to the cooking container ( 1 ).

As in 3 shown, the heating plate ( 2 ) from the induction coil ( 3 ) and the wave ( 5 ), which is located between the first floor ( 6 ) and the second floor ( 7 ) is located. The temperatures of the ferritic heating plate ( 2 ), which is preferably made of metal and within the working range of the coil, can reach 700 ° C-800 ° C, even more depending on the circuit capacitance.

The most important feature of the invention is that it induces a heating plate ( 2 ) with a suitable engine ( 4 ) is moved according to a specific pattern. The heating plate can first be moved slowly and then faster or at different speeds. This engine ( 4 ) may be a stepper motor, DC or AC motor, or a servomotor. The engine power can be set low or high depending on the use in the production; z. For example, in a coffee maker, a stepper motor is to be used while in a soup machine an AC or DC motor is suitable (because of the high speeds and power capacity).

As in 4a - 4b and 5a - 5b can be seen, there are flaps ( 21 ) with different shapes and several holes ( 22 ) on the heating plate ( 2 ). Through these flaps ( 21 ) gives a better mixture and a better foaming in hot drinks such as Turkish coffee. The amount of foam in the container increases due to the heating plate turned at a certain speed.
