CN 203776394 U relates to a dining table with a separate height-adjustable hot plate used for keeping warm the containers above the plate.
Furthermore, WO 2018/065742 A1 describes an integrated raclette table.
Various raclette devices are also known from the prior art, such as EP 1 396 219 A1 and EP 1 607 031 A1.
However, especially for the preparation of warm raclette dishes, there has not yet been a satisfactory solution that would successfully integrate the function of a raclette device into a dining table in a space-saving, ergonomic and operationally safe manner Problems arise especially in the gastronomy and hotel business, where the assembly and disassembly of raclette devices on tables means a considerable effort. The catering for larger groups, for which a large number of raclette devices usually has to be set up, is particularly time-consuming.
Embodiments of the present invention provide a dining table which, in particular, takes into account the disadvantages of the prior art and which is easy to operate and safe.
Summary
According to a first aspect, a dining table is provided having a support frame, a tabletop and an extendable section. The tabletop is supported on the support frame and includes a recess. The extendable section is received in the recess of the tabletop and comprises a pocket-shaped opening with one or more heating elements for heating a food portion, optionally multiple food portions. The extendable section is movable in the vertical direction of the dining table between a lowered position, in which the pocket-shaped opening is sunk in the recess, and a raised position, in which the pocket-shaped opening protrudes from the tabletop.
Optionally, the food portion is a raclette section and is optionally prepared in a raclette pan or scoop. Optionally, at least 5, at least 8 or at least 10 raclette scoops can be received and heated simultaneously in the pocket-shaped opening. Optionally, therefore, the extendable section serves for melting slices of cheese, rather than, for example, whole halves of cheese. However, the use of the table is not exclusively limited to raclette preparation. It can also be used for other purposes, such as reheating, grilling, cooking or baking a section of food.
The movement of the extendable section in the vertical direction allows the table to be used in the lowered position for everyday use as a dining table and in the raised position for use of the pocket-shaped opening with heating elements for heating the food portion. This saves the user a time-consuming assembly and disassembly, especially if the pocket-shaped opening and/or the integrated cooking device is used frequently. The built-in solution also has the advantage that no additional storage space is needed for the cooking device and the connecting cables. With the customized design it is also possible to make the dining table to be aesthetically pleasing and functional.
The pocket-shaped opening may have a base for depositing at least one container with a portion of food, optionally for depositing a plurality of containers with a respective portion of food portion. In this regard, in the raised position, the base of the pocket-shaped opening may be arranged at the same level as or above the tabletop, optionally at least 0.5 cm or at least 1 cm above the tabletop. In the raised position, the base may lie above the tabletop so as to prevent that the containers accidentally rest against the tabletop and that the elevated temperature of the containers in the area of contact with the tabletop causes undesirable burn marks.
Alternatively, or additionally, in the lowered position, the extendable section may protrude less than 5 cm above the tabletop, optionally less than 2 cm. Optionally, it does not protrude above the tabletop. In the lowered position of the extendable section, the height difference can be made relatively small for everyday use of the dining table.
The containers may be small pans (especially raclette pans or coupelles) or small pots. The containers may be open at the top.
Further, the pocket-shaped opening may have an inner side wall and/or a ceiling. Optionally, the pocket-shaped opening is open to the side and/or towards the tabletop. Due to the ceiling, a greater part of the heat initially remains inside the pocket-shaped opening. The ceiling may also allow radiant heat from heating elements disposed below the ceiling to be directed to the food portion(s). The ceiling may also reduce the risk of grease or oil splashing towards the user when cooking the food portion.
The inner side wall may form a supporting structure of the pocket-shaped opening. The inner side wall can connect the base with the ceiling.
The pocket-shaped opening can be formed circumferentially around the extendable section. This allows the table to be used flexibly by user groups of different sizes. It also facilitates cleaning. Furthermore, this makes it easier for users to place the food portion into the opening. In particular, a plurality of containers may be inserted into the pocket-shaped opening from each side of the dining table.
The extendable section may further have a lower side wall extending downward from the pocket-shaped opening (e.g., from its base). This avoids a gap between the opening and the tabletop, into which a finger could be inserted, for example. The safety for the user is thus increased.
The pocket-shaped opening may be supported on the table frame via the lower side wall. The lower sidewall may form a supporting structure of the pocket-shaped opening.
The pocket-shaped opening and/or the extendable section may be made of metal, optionally steel, for example stainless steel.
The material of the pocket-shaped opening may be thermally conductive.
The pocket-shaped opening, particularly its base, may be coated with a non-adhesive material, such as polytetrafluoroethylene. This may facilitate cleaning in the event of spillage of food portions.
Optionally, the one or more heating elements are heating loops. A heating element may extend at least partially or completely along the pocket-shaped opening around the extendable section.
Alternatively, or additionally, along the pocket-shaped opening, a plurality of heating elements may be arranged around the extendable section. The dining table may comprise at least eight, at least ten, or at least twelve heating elements (e.g., heating loops).
The plurality of heating elements may be spaced apart from each other. The heating elements may each be allocated to a seat.
Further, the dining table may be provided with a regulator and/or a control device for adjusting the heat output and/or the temperature of the one or more heating elements. The heat output and/or temperature of the plurality of heating elements may be adjustable individually or in subgroups, for example by a respective user. The dining table may comprise a plurality of regulators which allow a user to adjust the temperature and/or the heat output for an individual heating element or for a subgroup of the heating elements.
By allowing the heat output and/or the temperature to be regulated by a respective user at the seat, the cooking preparation may proceed in an individualized and controlled manner. However, it is often sufficient if the regulation is carried out centrally by one user. If the dining table is not used by the full number of users, the heating elements may be turned on individually or in subgroups.
Optionally, the heating elements are arranged along a straight section of the pocket-shaped opening at a minimum distance from each other of 20 cm or 40 cm. Alternatively, or additionally, the heating elements may be more closely arranged along a curved section or corner section of the pocket-shaped opening than along the straight section.
The one or more heating elements may be arranged below and/or along the ceiling.
The one or more heating elements may be disposed at a distance from the base, the distance optionally being at least 3 cm or at least 5 cm. The one or more heating elements may be configured such as to heat the food portion from above. Optionally, the one or more heating elements are configured such that the one or more containers deposited on the base may be arranged below the heating elements. This arrangement is particularly convenient for the preparation of raclette, because the cheese is melted from above.
Further, the extendable section may include a depositing surface. Optionally, the depositing surface is arranged above the base, adjacent a top surface of the ceiling, and/or substantially on the same level with the top surface of the ceiling. The depositing surface may rest on the extendable section and/or be detachable. Optionally, the extendable section includes a central recess and/or a supporting surface for receiving the depositing surface.
The depositing surface may be used as a shared use area in the center of the dining table where objects may be deposited and accessed in an easily accessible manner.
The depositing surface may be detachable from the extendable section (in particular without requiring tools). This facilitates cleaning of the depositing surface.
Optionally, the depositing surface rests on the extendable section by gravity only.
Optionally, the depositing surface is made of a material having a lower thermal conductivity than the pocket-shaped opening and/or of marble and/or stone. This prevents objects on the depositing surface from warming unintentionally.
The depositing surface may be integrally made or formed from a plurality of segments. The pocket-shaped opening may surround the depositing surface at least in sections or completely. The division into several segments has the advantage that the depositing surface is cheaper to manufacture and easier to detach.
The extendable section may comprise a hot plate. Optionally, the hot plate is arranged above the base of the pocket-shaped opening. The hot plate may form the afore-mentioned ceiling of the pocket-shaped opening. In this way, the heat from the heating elements below the ceiling and/or the hot plate can be used at the same time for heating the hot plate. The hot plate may offer an additional option for cooking preparation, such as fondue.
The hot plate may rest on the extendable section and/or be detachable therefrom (optionally without requiring tools). For cleaning, the hot plate may optionally be taken off from the extendable section.
Optionally, the hot plate rests on the extendable section by gravity only. This reduces the risk of crushing when the extendable section is lowered. Thus, the hot plate is raised if an object or finger should be in the pocket-shaped opening.
The extendable section may have a central recess and/or a supporting surface for receiving the hot plate. Optionally, the inner side wall of the pocket-shaped opening is configured to receive the hot plate. The inner side wall may surround the hot plate at least partially or completely.
The hot plate may be made of a material having a higher thermal conductivity than the supporting surface and/or of steel (e.g., stainless steel).
The hot plate may be coated with a non-adhesive material, such as polytetrafluoroethylene. In the event of spillage of food portions, this can facilitate cleaning.
The hot plate may be formed integrally or from several segments. A multi-segment design facilitates detachment for cleaning or in the event of an object being crushed.
The hot plate may form a heating surface for depositing at least one container with a food portion, optionally for depositing a plurality of containers with a respective portion of food. Optionally, the heating surface is disposed substantially flush with or below the depositing surface. The heating surface may be arranged at least 0.3 cm, at least 0.5 cm or at least 1 cm below the depositing surface. The heating surface may be surrounded by a radially inner raised edge and/or a radially outer raised edge. Optionally, the inner and/or outer raised edge is/are formed by the hot plate (in particular, being integrally formed therewith). Because of the edge, spilled liquid can be collected.
The dining table may further comprise a cover for the hot plate. Optionally, a top surface of the cover is substantially flush with the depositing surface. When the hot plate is not in use and has cooled down, it may be concealed by the cover. The flush surface prevents an elevation relative to the dining tabletop when the extendable section is in the lowered position.
The cover may be formed of several segments.
The cover may have a central opening and/or surround the depositing surface. In particular, the cover may be configured such that the depositing surface remains accessible even when the cover rests on the hot plate.
In operation, the heating elements may be supplied by one or more cables from a power source, for example with a voltage in a range of from 100 to 240 volts or of at least 400 volts (e.g., heavy current). A heavy current supply may accommodate the required energy consumption, especially if the table is designed for 8 or more persons.
The dining table may include a control device for controlling the heating elements and/or for controlling one or more movement members.
In operation, the heating elements may be controlled by one or more cables from a regulator and/or the control device. The control device may be configured such that the one or more heating elements cannot be turned on in the lowered position and/or such that the one or more heating elements can only be turned on in the raised position. This ensures that the heating elements are only turned on under safe circumstances, for example in the raised position.
The cables for the power supply are optionally concealed. In particular, the cables may extend in one or more channels underneath the tabletop. The one or more channels are optionally milled into the tabletop, at least in sections. The channels may be covered with a slat from below.
The control device may be configured to prevent movement of the extendable section from the raised position to the lowered position if the one or more heating elements are turned on. Alternatively, or additionally, the control device may be configured to prevent movement of the extendable section from the raised position to the lowered position before the one or more heating elements have been turned off for a predetermined minimum cooling time, the minimum cooling time, for example, depending on the duration of a previous operation of the heating element(s). Optionally, the control device does not prevent movement from the raised position to the lowered position if, prior to turning off, the heating elements have only been turned on for a short time, for example for less than 30 seconds. This prevents damage to the table.
Alternatively, or additionally, the dining table may include one or more temperature sensors, with the control device being configured to prevent movement of the extendable section from the raised position to the lowered position before the one or more temperature sensors determine that the temperature of the hot plate, the pocket-shaped opening, and/or the one or more heating elements is below a predetermined maximum temperature. This, too, may prevent damage to the table. The use of the temperature sensors may replace and/or supplement the regulation of temperatures by time.
In the raised position, a control device may automatically turn off the one or more heating elements after activation and a predetermined eating time, optionally of more than 4 hours. This can reduce the risk of accidents in the event of an accidental failure to turn off the table.
The above safety measures are particularly beneficial when users are allowed to use the table independently or when the table is accessible to users without supervision (e.g., when it is placed in accommodation to be rented, such as a chalet).
The heating elements along a curved section or a corner section of the pocket-shaped opening may be intermittently turned on and off. Optionally, these heating elements, after a predetermined on-time, may repeatedly be turned off automatically for a predetermined pause time, and then turned on again. The on-time may be at least 1 minute or at least 2 minutes. The pause time may be at least 10 seconds or at least 20 seconds.
In order for the cooking preparation to be similar for all users of the dining table, it is desirable that the heating elements have an even temperature distribution. Since the heating elements are closer together in a curved or a corner section than in a straight section, the food portions can be prepared more quickly there. The intermittent turning on and off the heating elements in a curved or a corner section extends the preparation time so that users can enjoy the meal at the same pace.
The control device may be arranged in a fire protection housing. Optionally, the housing is made of gypsum fiber. The control device may be arranged below the depositing surface in the extendable section, optionally on one or more crossbeams of the extendable section. The extendable section may be covered from below by a cover, for example made from aluminum. This increases safety, for example in the event of accidental short circuits. The cover below the extendable section can prevent access from below, e.g., by children.
The support frame may comprise at least two extendable columns, the upper end of the columns being configured to receive the extendable section. The extendable columns may comprise a fixed section and a movable section, the upper end optionally being formed by the movable section.
Furthermore, the support frame may comprise at least two support columns, the upper end of the support columns being configured to receive the tabletop. The support columns may be connected with the extendable columns, for example with the fixed section thereof. The extendable columns may each comprise a movement member, optionally an electric or hydraulic lifting cylinder. The extendable columns may each comprise a section for receiving the movement member.
The extendable columns may provide an end stop for the extendable section in the lowered position, optionally for the crossbeam of the extendable section. The end stop may be formed by an end stop section for receiving the extendable section and/or the crossbeam in the fixed section. Optionally, the end stop section determines the end position of the extendable section in the lowered position.
The tabletop may comprise an end stop section for receiving the extendable section in the raised position, optionally a crossbeam of the extendable section. In the raised position, the extendable section may abut the end stop section of the tabletop from below. The end stop section may define the end position of the extendable section.
Optionally, the extendable columns and/or the support columns comprise one or more recesses for the cables. These recesses may form cable guides.
The tabletop may have one of the following shapes: oval, circular, rectangular, hexagonal, octagonal. The extendable section, the pocket-shaped opening, the depositing surface, and the hot plate may have one of the following shapes: oval, circular, rectangular, hexagonal, octagonal.
The shape of the tabletop may be designed according to the seating plan of the users. An even distribution of persons is aimed at, where users may also sit facing each other. In particular, accessibility to the common use area, namely the depositing surface, may be made as easy as possible. For the same reason, the extendable section, the pocket-shaped opening, the depositing surface, and the heating plate may be shaped according to the desired use.
Optionally, the tabletop has one or more recesses for the cable guide, for example on the lower side of the tabletop.
The dining table and/or an ensemble including the dining table may further comprise an extractor fan and/or a bench.
