DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
Background
The present invention relates to a steamer. Steamers are appliances making it possible to defrost and/or heat and/or cook food by means of steam. Steamcooked food has more vitamins, a higher nutritional value, natural colors, its own particular aroma, etc. This is not the case when food is prepared in another way.
One of the steamers already known contains a double-walled cooking space, the inner side walls of such a cooking space each being equipped with two vertically extending rows of nozzles. Arranged under the cooking space is a water bath, in which heating elements are located and in which steam is generated from tap water. The steam first passes into the cavity limited by the two walls of the cooking space, and from there steam flows through the said nozzles into the cooking space. The cooking space is provided with an orifice, through which the steam cooled by the cooking food and condensation water is able to leave the cooking space. The known steamer is also equipped with a control device which makes it possible to set the cooking times required and which allows the individual parts of such a steamer to interact with one another.
This known steamer has two essential disadvantages. it generates steam at a constant temperature, so that for relatively large quantities of cooking food the treatment time has to be extended correspondingly. Limestone is deposited in the steam generator, thus causing disturbances in the operation of this known steamer.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a steamer which does not have the disadvantages mentioned.
According to the invention, this object is achieved in the way defined in the characterizing clause of claim 1.
Exemplary embodiments of the present invention are explained in detail below with reference to the attached drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows the present steamer diagrammatically,
FIG. 2 shows a side view of a first heater of the steamer according to FIG. 1, this heater being shown horizontal in the drawing for reasons of space.
FIG. 3 shows a plan view of the heater according to FIG. 2,
FIG. 4 shows a side view of a second heater of the steamer according to FIG. 1,
FIG. 5 shows a front view of the heater according to FIG. 4,
FIG. 6 shows a side view of the door of the steamer according to FIG. 1,
FIG. 7 shows a front view of a steam distribution means accommodated in the cooking space of the steamer according to FIG. 1,
FIG. 8 shows a side view of the distribution means according to FIG. 7,
FIG. 9 shows a side view of another design of the second heater,
FIG. 10 shows a bottom view of the heater according to FIG. 9, and
FIG. 11 shows a U-shaped heating element, together with helical ribs attached to it, of the second heater.
DETAILS
The steamer illustrated in FIG. 1 has a housing 1, in which is accommodated a container 2 intended for receiving the food to be treated (not shown). This container 2, also designated as a cooking space, can be closed at the front by means of a door 3. A steam distribution means 4 is arranged in the cooking space 2. The middle portion of the distribution means 4 is fastened in the region of the rear wall of the container 2. Also located inside the housing 1 of the present steamer is a first heater 5 which is intended for generating wet steam from tap water. Connected to this first heater 5 via a connecting pipe 7 is a second heater 6 which serves for heating steam emerging from the first heater 5. The second heater 6 is connected via a second connecting pipe 8 to the distribution means 4 and consequently also to the cooking space 2. The steamer also has an electronic control device 9 which controls the interaction of the individual parts of the steamer according to predetermined programs and which is shown merely diagrammatically in FIG. 1.
As is evident from FIG. 1, the first heater 5 has an essentially cylindrical boiler 10, the axis of this boiler extending vertically. For reasons of space, the boiler 10 is shown
