Description

The invention relates to a system consisting of at least one electric kitchen appliance, in particular a cooking element, and a kitchen worktop, in or on which the electric kitchen appliance can be arranged.

In many applications, there is a need to make the space available for the kitchen very compact in order to accommodate the kitchen in confined spaces. For example, in hotel rooms, in apartments, in holiday apartments or in single households, there is a constant need to accommodate the equipment required for completing the tasks in the kitchen in the smallest possible space. These devices include in particular the electrical kitchen appliances, especially for cooking.

A particular problem is that usually different electrical kitchen appliances are needed to do all culinary work. In particular, sometimes different sized hotplates for the preparation of various foods are required. Other tasks in the kitchen require a fryer. Very useful to use are kitchen induction cookers which, however, have the disadvantage that special pots are required to make use of this technology. If not all pots are made of (ferromagnetic) material, it may be necessary to have an induction cooker as well as one that heats in the classical way, ie by means of heating spirals.

The usually available in a kitchen space is not sufficient to accommodate any electrical equipment may be required. Therefore, a compromise will mostly have to be concluded with regard to the electrical appliances to be provided in the kitchen.

The invention is therefore an object of the invention to provide a system of the type mentioned, with which it is possible to provide a variety of electrical equipment available, yet to be handled very economically with the available space in the kitchen , An easy-to-use multifunctional design should be achieved.

The solution of this problem by the invention is characterized in that the at least one kitchen appliance is designed as a module which can be arranged interchangeably on or in the kitchen worktop.

In this case, a plug connection is preferably present for the electrical supply of the kitchen appliance. For the mechanical fixing of the kitchen appliance in the kitchen worktop is preferably a receptacle or recess and a holder available.

The receptacle or recess and the holder may be formed so that they are suitable for supporting the kitchen appliance on the kitchen worktop from above. The holder is advantageously designed as around the kitchen appliance peripheral edge.

The plug connection can be designed so that the electrical contact between a power supply and the kitchen appliance is made when placing or inserting the kitchen appliance in the receptacle or recess of the kitchen worktop. In this case, a part of the plug connection at least two electrical Having pin-shaped plug contacts, which point in the intended use of the kitchen appliance in the vertical direction. The part of the plug connection with the electrical pin-shaped plug contacts is preferably arranged on the kitchen appliance. A part of the plug connection can have at least two recesses corresponding to the pin-shaped plug contacts and, when the kitchen appliance is used as intended, having vertically aligned recesses. In this case, the part of the plug connection can be arranged with the recesses on or in the kitchen worktop.

For the mechanical fixing of the kitchen appliance in the kitchen worktop, a frame with lateral contact surfaces may be present. Furthermore, at least one latching connection element can be present for the mechanical fixing of the kitchen appliance in the kitchen worktop. At least two latching connection elements can be present on at least two, preferably opposite sides of the receptacle or recess.

The latching connection element is preferably designed as a spring clip. The spring clip can have a V-shaped contour in its side view.

The frame may have at least one transverse strut with which it can be divided into at least two receptacles or recesses for two kitchen appliances.

The kitchen appliance may have a single stove top. It can also have a fryer or represent. Further, it may have two or more cooking plates. It may also have at least one induction hearth plate. Another possibility provides that the kitchen appliance is an extractor hood.

In addition to an electrical kitchen appliance can also be provided that the system further comprises an insert whose surface is designed as a worktop. Furthermore, it is possible that the system further comprises an insert whose surface is designed as a cutting board. A further embodiment provides that the system further comprises an insert, on the surface of which a storage compartment is arranged.

The insert is designed to be inserted into the recess provided for the kitchen appliance in the kitchen worktop. This further increases the multifunctionality of the system.

The proposal according to the invention so electrical kitchen appliances are provided as various units that form a modular system that is designed to be interchangeable for the user. This is achieved in an advantageous manner that the possibility is created to make more flexible use of the available different kitchen appliances, especially cooking systems. An exchange of the various modules can be done by the user directly and without additional installation and assembly costs. Without much space, it is possible to use the full range of functions of the various kitchen appliances on their interchangeability. This saves working and cut-out area in the kitchen area or in the worktop.

In FIG 1, a system 1 is shown, which consists of a kitchen worktop 6, are used in the module designed as kitchen appliances 2 and 3. The kitchen appliance 2 is present a single stove top; the kitchen appliance 3 is a fryer in the embodiment. Both kitchen appliances 2, 3 are fully functional in the state inserted into the kitchen top 6, i. they are both mechanically fixed or locked and electrically connected to a power supply.

The equipment required for this purpose kitchen worktop 6 can be seen in Figure 2. In the kitchen worktop 6, a recess is cut, which serves to hold kitchen appliances, not shown here. The cutout in the kitchen worktop 6 is provided with a frame 17, which carries in the embodiment shown in Figure 2 in the middle a cross strut 20. As a result, two receiving openings for kitchen appliances are created. So that they can be electrically connected, a part 7a of a plug connection is arranged in the rear region of the recess, approximately centrally within a receiving region. As will be seen, this part 7a of the plug connection is designed so that automatically results in the insertion of a kitchen appliance in the receiving opening an electrical contact.

By way of example, in FIGS. 3 and 4, two electric kitchen appliances 4 and 5 are sketched, which are inserted into the receiving openings in FIG the kitchen worktop 6 can be used according to Figure 2. The kitchen appliance 4 is a cooking module with two hotplates. The kitchen appliance 5 is intended to be an induction cooker for two cooking zones.

Details on the design of the receiving opening in the kitchen worktop 6 are apparent from Figures 5 and 6. The receiving opening is provided with a frame 17 which forms a receptacle 8 for a kitchen appliance. The frame 17 has lateral abutment surfaces 18, which are designed so that they can accommodate a kitchen appliance with little play.

So that a kitchen appliance sits securely after insertion into the recess of the kitchen worktop 6, a number of latching connection elements 19 are provided along the lateral contact surface 18.

These are spring clips with a cross-sectionally V-shaped contour. As can be seen from the illustration of the snap-in connection elements 19 in FIG. 5, these are designed so that when the kitchen appliance is inserted into the corresponding receptacle, the latching connection elements 19 engage in corresponding recesses in the edge region of the kitchen appliance. Thus, a kitchen appliance is securely locked after insertion into the kitchen worktop 6, which is supported by the weight of the kitchen appliance. The kitchen appliance can then be taken out of the receptacle again only by applying a force against the direction of gravity.

For electrical coupling of a kitchen appliance, reference is made to FIGS. 7 to 12.

FIG. 7 shows a kitchen appliance 3 embodied as a fryer, which has not yet been inserted into the recess in the kitchen worktop 6. At the back of the kitchen appliance There is a part 7b of the plug connection, via which electrical contact can be made to a power supply 10. The electrical connection is created as soon as the trained as a holder 9 edge of the kitchen element rests on the surface of the kitchen worktop 6. An enlarged view of the constellation sketched in FIG. 7 is shown in FIG. 8.

From Figures 9 and 10 shows how the part 7b of the plug connection is executed. In the present case, three pin-shaped plug contacts 11, 12 and 13 are provided, which are part of the one part 7b of the plug connection. The three pin-shaped plug contacts 11, 12, 13 are arranged so that when used according to the kitchen appliance 2, 3, 4, 5 show the plug contacts in the vertical direction.

FIG. 11 shows the other part 7a of the plug connection. It has - corresponding to the three plug contacts 11, 12, 13 (see Figure 9) - three recesses 14, 15 and 16, which are arranged in the rear region of the frame 17 so that their longitudinal axis points in the vertical direction.

If a kitchen appliance is inserted into a recess in the kitchen worktop 6, this automatically results in that the electrical contact is made via the parts 7a and 7b of the plug connection.

The proposed invention therefore provides a fastening rail concept that is arranged in the corresponding cutouts in the kitchen worktop. The mounting rails can be provided in different lengths with the particular pitch of a series of kitchen appliances. Typical grid dimensions are z. B. 30 cm or 36 cm.

By the latching connection elements 19 a reliable locking of the kitchen appliances in the kitchen worktop 6 is ensured, since they can produce a downward traction.

As shown, the electrical contacting preferably takes place via single-phase sockets. A secure contact is ensured by the weight of the kitchen appliances in conjunction with the tensile force generated by the latching connection elements 19.

The user of the kitchen has the opportunity to use or exchange the required modules individually according to his specific requirements and wishes. Rarely used units can be stored separately, for example in a kitchen cupboard.

Kitchen appliances may include radiant hot plates, induction hobs, wok units, grill plates, Teppan Yaki, fryer modules and combinations thereof. Furthermore, it is also possible to use a cooker hood as a kitchen appliance in the kitchen worktop; For this purpose, if appropriate, provide a corresponding line for exhaust air.

In general, with a single-phase connection of the kitchen appliances a maximum power of 3.7 kW connected load is provided. An extension of the system is also possible to other grid dimensions (eg 58 cm or 72 cm) with, for example, four cooking zones. For this purpose, the electrical contacting of the modules with two phases will be done in a similar manner.

It is also possible, with a basic design in a first grid dimension (for example 36 cm), to provide an expansion to a grid size of twice the size (for example 72 cm). This would then be the crossbar 20 removed, and it would be two plug connections 7a / 7b used for the electrical supply. Such a module would then be equipped with two separate connector units.

As an additional feature a cover module for covering unequaled module slots is conceivable. An embodiment as a worktop, cutting board or an element with other functions is equally possible, for. B. with storage compartments or special containers.
