Description

BRIEF SUMMARY OF THE INVENTION

[0001] The present invention concerns the technical field of steam cooking appliances.

[0002] Steam cookers have a cooking enclosure disposed on a base for producing steam. The steam production base can have or not have a self-contained means for heating water. The cooking enclosure generally has one or several superposed cooking vessels closed by a cover. The cooking vessels have a bottom provided with perforations for the passage of steam, as well as a peripheral lateral wall. The bottom of the cooking vessels can be removable to obtain one cooking enclosure with a larger size. If need be, a tray for recovery of juices can be disposed under a cooking vessel.

[0003] To reduce the size of these appliances, it is known to use superposed nested cooking vessels. During cooking, the size of the cooking vessels increases from the bottom toward the top of the appliance. For storage, the order of the cooking vessels is reversed and the size of the cooking vessels decreases from the bottom toward the top. This arrangement permits the height of the appliance to be reduced when in the storage position. However, the height of the appliance in the storage position remains greater than that of an appliance having only a single cooking vessel.

[0004] To obtain an even more compact storage, it has been proposed to produce a steam cooker with nested bowls in which the steam production base can be stored in the smallest cooking bowl. This arrangement presents, however, the drawback of placing the lower part of the base, that is normally in contact with the working surface, in a cooking vessel. It is thus necessary to lift the base of the appliance, which can still contain water. In addition, the electric cord coming from the base of the appliance interferes with storage. Also, the appliance disposed in the storage position rests on the lower part of a cooking bowl. These arrangements are particularly restricting in terms of storage and cleaning, and risk leading to problems of cleanliness if the user is not sufficiently careful.

BRIEF SUMMARY OF THE INVENTION

[0005] The present invention provides a steam cooker having a particularly compact storage configuration.

[0006] The present invention, in particular, provides a steam cooker having a particularly compact storage configuration, without requiring restricting manipulations.

[0007] The present invention also provides a steam cooker having a particularly compact storage configuration, without requiring particular cleaning restrictions.

[0008] More specifically, a steam cooker according to the invention comprises a cooking element having a peripheral lateral wall intended to be placed on a pedestal having a steam production base surmounted, if need be, by a vessel for recovering juices and/or a cooking support, by the fact that the cooking element can be disposed in an inverted position on the pedestal, the peripheral lateral wall at least partially enveloping the pedestal. Such a construction permits the attainment of a particularly compact storage configuration. In addition, the user does not have need to handle the pedestal of the steam cooker in order to obtain this configuration. The cooking element can have a bottom in order to form a cooking vessel. The bottom of the cooking vessel can be removable. The cooking element can also be without a bottom. A cooking support is then disposed between the cooking element and the steam production base. The cooking support can occupy a very reduced height.

[0009] Advantageously then, the cooking element has a bottom resting on a pedestal when the cooking element is disposed in the inverted position on said pedestal. This arrangement permits avoidance of contact of the lateral walls of the cooking element with the working surface. This arrangement equally permits wedging of the lateral walls of the cooking element with the lateral walls of the pedestal of the steam cooker to be avoided. The cooking element forms a cooking vessel.

[0010] The steam cooker can advantageously have several superposed cooking elements each having a peripheral lateral wall, these cooking elements being nested to obtain a compact storage. The smallest cooking element is disposed on the pedestal and the other elements are superposed by increasing size. The cooking element placed in the upper position is the largest cooking element. Thus, the cooking elements can be inverted on one another for storage.

[0011] Advantageously, the steam cooker comprises a lid provided to close the cooking element that is furthest from the pedestal, the lid having a skirt able to envelop the lower part of the peripheral lateral wall of said cooking element disposed in the inverted position. This arrangement permits protection of the bottom of the upper cooking element inverted on another vessel, or the bottom of the single inverted cooking element on the pedestal of the steam cooker, while retaining a good compactness. In addition, this arrangement permits avoiding the entry of dust into the cooking element or cooking elements as well as into the pedestal.

[0012] Advantageously then, for a better stability of the lid, the skirt comes to bear on the lower part of the peripheral lateral wall of said cooking element disposed in the inverted position.

[0013] Also advantageously, the vessel for recovering juices has lateral recesses intended to facilitate gripping.

[0014] Also advantageously, gripping organs are disposed on the upper part of the cooking element or elements. This arrangement permits retention of a compact stacking while facilitating gripping of the cooking element or elements.

[0015] Also advantageously, the pedestal has a retractable filling device. This arrangement permits the compactness of storage to be reconciled with ease of filling.

[0016] Advantageously then, the retractable filling device is arranged under the vessel for recovering juices. This arrangement permits a better compactness than an arrangement in the heating base. In effect, the arrangement under the vessel for recovering juices occupies only a part of the surface of the vessel for recovering juices while an arrangement in the heating base occupies the totality of the surface of the heating base over a given height, because of sealing problems impeding a filling up to the level of the retractable filling device. By this fact, for the same reservoir water capacity, the arrangement of the retractable filling device under the vessel for recovering juices permits a lower height.

[0017] Advantageously then, the retractable filling device is arranged under a raised part of the bottom of the vessel for recovering juices. This arrangement permits optimization of the space occupied by the vessel for recovering juices without affecting its capacity.

[0018] According to an advantageous form of construction, the retractable filling device has a drawer arranged under the bottom of the vessel for recovering juices. According to another advantageous form of construction, the retractable filling device can have a movable lateral wall forming a filling chute. The lateral wall is for example movable about a horizontal axis of rotation.

[0019] Also advantageously, the drawer is pivotably mounted under the bottom of the vessel for recovering juices along an axis of rotation. Other forms of construction such as a slidably mounted drawer can equally be envisioned.

[0020] Advantageously, an outer annular lateral wall of the pedestal surrounds a rice bowl disposed in inverted position on the pedestal. This arrangement permits conserving a good compactness in the storage position despite the storage of a supplementary accessory.

[0021] Advantageously then, the rice bowl has a handle housed above the raised part of the bottom of the vessel for recovering juices. This arrangement permits reconciling compactness with ease of gripping.

[0022] Advantageously then, in order to facilitate the installation of the filling device, the handle extends from a lateral face of the rice bowl, said lateral face being curved inwardly toward the interior of the rice bowl.

[0023] According to one form of construction, the cooking element disposed in an inverted position on the pedestal rests on the rice bowl.

[0024] Advantageously also, the base has gripping organs.

[0025] The invention will be better understood from a study of three examples of construction and one variant, taken in a way that is not in any way limiting, and illustrated in the attached figures.

DETAILED DESCRIPTION OF THE INVENTION

[0034] FIG. 1 shows a steam cooker comprising a steam production base 1, a vessel 2 for recovering juices, cooking elements 3, 4, 5 and a lid 6, arranged in a superposed manner.

[0035] Base 1 comprises a water reservoir 10 communicating with a boiling chamber 11 in which is arranged a heating element 12. A crown 13 delimits reservoir 10 and chamber 11. Base 1 presents an exterior lateral wall 14. Water reservoir 10 is mounted on a baseplate 19. The electric parts of the appliance are housed in baseplate 19. Gripping organs 70 are disposed on lateral wall 14 of base 1. Gripping organs 70 are formed by two diametrically opposed handles extending from baseplate 19. Gripping organs 70 protrude with respect to lateral wall 14.

[0036] Vessel 2 for recovering juices disposed on base 1 has a bottom 20 provided to collect cooking juices or condensates flowing from cooking elements 3, 4, 5. A chimney 21 extending from bottom 20 presents lateral walls 22 and a roof 23. Lateral walls 22 present in their upper part perforations 24 provided for the passage of steam coming from boiling chamber 11. An exterior annular lateral wall 25 surrounds bottom 20. The height of chimney 21 is less than the height of outer annular lateral wall 25.

[0037] Vessel 2 for recovering juices has a filling device 7 for reservoir 10. Filling device 7 is retractable. Filling device 7 comprises a drawer 26 mounted under bottom 20 of vessel 2 for recovering juices. Drawer 26 is mounted pivotably around an axis of rotation 27. Axis 27 extends from the lower face of bottom 20. Drawer 26 is disposed under a raised part 28 of bottom 20. More particularly, axis 27 extends from raised part 28. Drawer 26 presents a bottom wall 29 inclined toward the interior of reservoir 10, in a manner to aid the flow of water into reservoir 10. Outer lateral wall 14 of base 1 presents an upper indentation 15 provided to house drawer 26. A skirt. 18 is arranged under bottom 20 of vessel 2 for recovering juices. Filling device 7 is disposed outside of skirt 18.

[0038] Vessel 2 for recovering juices presents an outer annular lateral rib 16 resting on steam production base 1. Outer annular lateral wall 25 presents above rib 16 lateral recesses 17 intended to facilitate gripping of vessel 2 for recovering juices.

[0039] Each of cooking elements 3,4,5 presents a peripheral lateral wall 35,45,55. The smallest cooking element 3 presents a bottom 30 fixed with respect to peripheral lateral wall 35. Middle cooking element 4 presents a bottom 40 removable with respect to peripheral lateral wall 45. The largest cooking element 5 presents a bottom 50 removable with respect to peripheral lateral wall 55. Cooking elements 3,4,5 can form independent cooking vessels when removable bottoms 40,50 are in place. Cooking elements 3,4,5 can equally form a larger cooking vessel when at least one of removable bottoms 40,50 is withdrawn.

[0040] Removable bottoms 40,50 have hanging feet 41,51 described in detail in the document WO 00/30511. Gripping organs 32,42,52 are disposed on the upper part of cooking elements 3,4,5. Each of the gripping organs 32,42,52 is for example formed by an other flange having in its upper part a shaped part 33,43,53 provided to receive the lower part of a skirt 60 of lid 6. Thus, lid 6 can be adapted to each of cooking elements 3,4,5.

[0041] Cooking elements 3,4,5 are nested. During cooking, such as represented in FIG. 1, the largest cooking element 5 is placed under the lid, the smallest cooking element 3 is placed on vessel 2 for recovering juices, and the middle cooking element 4 is placed between the other elements. For storage, such as represented in figure. 2, the smallest cooking element 3 is placed in middle vessel 4 which is placed in the largest cooking element 5.

[0042] More particularly according to the invention, the smallest cooking element can be inverted on vessel 2 for recovering juices placed on base 1. Cooking elements 4,5 are equally stacked in an inverted fashion. Lid 6 is placed on the largest cooking element 5. Thus in the storage position of the appliance, pedestal 8 formed by base 1 and vessel 2 for recovering juices remains in place on the working surface. The user does not have need to handle pedestal 8 of the appliance only cooking elements 3,4,5 are inverted on pedestal 8, for example after having been washed.

[0043] Lid 6 can retain its position used during cooking. Skirt 60 of lid 6 is provided to envelop bottom 50 of the largest cooking element 5 when this latter is inverted. As shown in FIG. 2, skirt 60 comes to bear on the lower part of peripheral lateral wall 55 of inverted cooking element 5. Peripheral lateral wall 45 of middle cooking element 4 is disposed between peripheral lateral walls 35;55 of cooking elements 3;5 when these latters are inverted. Peripheral lateral wall 35 of the smallest cooking element 3 is provided to envelop vessel 2 for recovering juices placed on base 1 when cooking element 3 is inverted. Gripping organs 70,32,42,52 are superposed, which permits the user to move the steam cooker disposed in the storage position by grasping gripping elements 70 of the base as well as gripping organs 32,42 or 52 of the cooking elements, regardless of the number of cooking elements 3,4,5 disposed on pedestal 8 in the inverted position.

[0044] Thus, peripheral lateral wall 35 of cooking element 3 envelops at least partially pedestal 8 of the steam cooker.

[0045] Base 1 has an electric cord 80 and a timer 71 disposed below cooking element 3 disposed on pedestal 8 in the inverted position, such as is visible in FIG. 3. Electric cord 80 extends from baseplate 19. Electric cord 80 can remain connected even when the steam cooker is in the storage position. Timer 71 is mounted on the lateral wall of baseplate 19.

[0046] FIG. 4 shows a steam cooker having a steam production base 1′, cooking elements 3′,4′,5′ and a lid 6′ arranged in a superposed manner. This variant of construction differs from the preceding example of construction in that pedestal 8′ of the steam cooker has a steam production base 1′ but not a vessel for recovering juices. Lower cooking element 3′ rests on base 1′.

[0047] Base 1′ has a water reservoir 10′ communicating with a boiling chamber 11′ in which is arranged a heating element 12′. A crown 13′ delimits reservoir 10′ and chamber 11′.
