Definitions
- the present invention relates to improvements in cooking utensils. More specifically, the invention relates to pots, boilers, and the like, which comprise means to enable the contents of the pot, boiler, or the like, to be cooked at reduced pressure i.e. under a partial vacuum, and means to indicate whether the contents of the pot, boiler, or the like, are at, or approaching boiling point.
- pots, boilers, and the like which comprise means to enable the contents of the pot, boiler, or the like, to be cooked at reduced pressure i.e. under a partial vacuum, and means to indicate whether the contents of the pot, boiler, or the like, are at, or approaching boiling point.
- a closable cooking vessel having valve or vent means therein adapted to allow steam and air to be expelled therefrom such that the interior of the cooking vessel can be mantained under conditions of partial vacuum.
- a closable cooking vessel which comprises means - preferably in the lid or cover thereof - which provide .an audible indication that the contents thereof are at, or are approaching, boiling point.
- a plurality, or a set, of cooking vessels i.e. covered pots, saucepans, boilers or the like
- a covered pot, saucepan, boiler or the like of the type described above adapted to act as a low-pressure-type pressure cooker, which comprises a pot etc., having means to retain the cover thereof on the said pot against low steam pressure which may build up in the pot but allows the escape of built up steam once a predetermined pressure is attained, in order that said predetermined pressure is not exceeded.
- Water-boiling devices such as jugs or kettles, comprising whistle means activated by escaping steam are known.
- various type of pressure cookers which comprise audible means - either inherent, built-in, or added - which indicate a release or an escape of steam from within the pressure cooker.
- conventional cooking utensils which may be termed pots, saucepans, boilers or the like which comprise audible indicators of steam release, are not 10 available.
- a steam whistle-type indicator be incorporated in the lid or cover of the pot.
- the knob or handle be adapted to include the whistle-type indicator therein.
- each saucepan be provided with a whistle-type indicator having a different tone (or a whistle of which the 20 tone or pitch may be varied) to other saucepans in the set.
- a whistle-type indicator having a different tone (or a whistle of which the 20 tone or pitch may be varied) to other saucepans in the set.
- the lid of the cooking vessel is provided with a rotatable central knob with 30 a plurality of whistle cavities therein about the periphery
- knob is rotatable to selectively align one of said plurality of whistle cavities with a venting orifice provided in lid of the cooking vessel. Steam emitted from the orifice is forced through and out of the aligned whistle cavity to produce a whistle sound.
- the whistle cavities would be designed such as to give a distinct whistle sound.
- a set of cooking vessels could be provided with lids having the above described rotatable multi-whistle knob, with a different whistle being selected (by rotation of the knob) for each cooking vessel - for identification purposes.
- the cover or lid of the pot or saucepan may, if required, be retained on the pot or saucepan by means of spring-loaded or spring-biased retaining means which allow escape of steam and built up pressure at a predetermined pressure.
- the whistle-type indicator built into the lid or cover of the cooking utensil is preferably also adapted to allow the escape of steam by acting as a steam pressure by-pass valve.
- Fig. 1 is a sectional side-elevational view of a cooking vessel according to the present invention, having a rotatable, multi-whistle knob on the lid thereof;
- Fig. 2 is a perspective view of the lid of the cooking vessel of Fig. 1;
- Fig. 3 is a sectional side-elevational view of another lid of a cooking vessel, according to the invention, wherein a fixed whistle is incorporated on the inside surface of the lid.
- the cooking vessel illustrated comprises a container 1 having a lid 2 adapted to seal the container.
- the lid has a central knob 3 which is rotatable in the directions shown by arrows (Fig. 2).
- the rotatable knob 3 comprises four radially extending arms 4, 5, 11 and 12, each identified by a numeral thereof ("1", "4", - s-
- Each arm houses a whistle chamber (see 7 and 9 in Fig. 1) which may be selectively aligned with a steam venting orifice 6 in the lid. Steam entering a whistle chamber via orifice 6 and exiting by an orifice in each arm (orifices 8 and 10 in Fig. 1; orifices 8 and 13 in Fig. 2) creates a whistle tone, the pitch of which is determined by the configuration of the whistle chamber the steam venting orifice and the exiting orifice in each case.
- the whistle in each of the radial arms is adapted to have a characteristic pitch which enables the numbered radial arm (i.e.
- FIG 3 illustrates another embodiment of the invention wherein a lid 14 of a cooking vessel has a central knob 15 and a permanent whistle chamber 16 affixed to the underside of the lid where steam enters the steam venting orifice 17 and is forced into the whistle cavity or chamber before expulsion through the external orifice 18 to produce a shrill whistling sound.
- the external or exciting orifice and/or the steam venting orifice may be provided with a one-way flap valve to ensure that air cannot enter the cooking vessel, thus maintaining the conditions of partial vacuum within the cooking vessel.
- the cooking of the contents of a cooking vessel according to the invention takes place under a partial vacuum due to the continuous escape or expulsion of steam and entrained air. That the inner space of the cooking vessel is under reduced pressure (or partial vacuum) can be readily demonstrated by the initial slight resistance to removal of the lid of the cooking vessel. However, the lid can be removed for inspection purposes or for addition of further ingredients (c.f. a conventional pressure cooker which must be slowly de-pressurised before opening).
- Food is cooked faster, saving up to 70% of the normal cooking time. Food cooked in this way maintains a firmer texture and has more nutrition and flavour, due to the shorter cooking time. There is also a resultant saving in the fuel used for cooking. In addition, there is less chance of the contents of the cooking vessel of the present invention boiling over, thus thre is also a saving in time devoted to cleaning of the cooking vessel and the surface of the stove or other cooking appliance.
