Technical Field

The invention relates to a gas cooker.

Background

Gas cooktops typically include a top plate and a gas burner. The respective gas burner is associated with a gas valve for supplying fuel gas. The gas valve is typically provided below the top plate. The fuel gas is mixed with primary air to obtain a combustible gas/air mixture which is burned at the opening of the gas burner. A respective pan support for supporting a pan or kettle is associated with each gas burner.

CN206160207U discloses a modular gas hob with several gas burners and burner modules, wherein one gas burner is connected to one burner module. These gas burners are supplied with fuel gas via a burner module. If the gas hob is not used, the gas burners may be disconnected from the burner modules.

Disclosure of Invention

It is an object of the present invention to provide an improved gas hob.

Accordingly, a gas hob is provided, comprising: a top plate; a connection rail having a plurality of ports and disposed on the top plate; and a gas burner disposed on the top plate and releasably connected to a port of the connecting rail, the port being configured to supply fuel gas to the gas burners.

Thereby, a compact gas hob is created, which can be established by connecting one or more gas burners to a single connecting rail according to the needs of a user.

The top plate may be made of metal, glass, ceramic, and/or glass-ceramic. The top plate may also be of the same material as e.g. a common kitchen worktop, e.g. stone (especially granite). Thus, the top plate may be a cooking area of a kitchen work top and/or a continuous kitchen work top.

A releasable connection of a gas burner to a port herein relates to a respective fluid connection that can be established (connected), i.e. fluid can flow from the port to the gas burner, and released (disconnected), i.e. fluid can not flow from the port to the gas burner. "fluid" means in particular a gas. The fluid connection may also comprise a mechanical connection comprising engagement elements such as recesses, protrusions, pins, hooks, threads, screws, etc. engaging each other. The respective port may comprise an injector for injecting fuel gas into the respective gas burner, in particular into a duct or venturi portion thereof.

The gas hob preferably comprises a single connection rail for connecting all gas burners. For example, 2, 3, 4, 5, 6 or more ports (for supplying gas) and corresponding gas burners are provided. The fuel gas and primary air may be mixed directly at each gas burner, within the connecting rail, or under the ceiling using, for example, venturi sections and injectors. Preferably, the gas hob is configured such that a user may choose to connect a single gas burner to one port, to connect some gas burners to some ports or to connect a gas burner to each port at any time.

The connecting rail is preferably an elongated element, the length of which is for example at least twice its width. For example, the connection rail may have a strip shape. The connecting rail may have a rectangular or square cross-section. The connecting rail may be at least partially made of metal. These gas burners can be detached from them when they are not in use. The ports are designed to prevent the discharge of fuel gas if the gas burner is not connected to a specific port, especially when some ports are connected to the respective gas burner and some ports are not connected.

According to an embodiment, the ports are arranged on different sides of the connection rail.

In this way, the gas burners can be connected to the connecting rail on different sides and the space (surface area) on the ceiling can be used more efficiently. "different sides" side encompasses opposite sides, sides connected via one or more corners, and the like.

According to a further embodiment, the ports are arranged on opposite sides of the connection rail.

According to a further embodiment, the connecting rail projects vertically upwards from the top plate.

Perpendicular means that the sides of the connecting rails, in particular the side panels, have an angle of 90 degrees (including deviations of up to 10 or 20 degrees) with respect to the top panel.

The connecting rails may be provided on the top panel so as to extend away from the user (in its longitudinal dimension), which improves the efficient use of the kitchen surface.

According to a further embodiment, the connection rail is arranged in the center of the top plate.

This means that the connecting rail passes through the center of the top plate in top view.

According to a further embodiment, the connection rails are arranged equidistant from the opposite edges of the top plate.

This allows to arrange these gas burners in a space efficient manner. The edges can be understood in such a way that: the edge is the gas cooktop-confining side of the top plate. Equidistant does not necessarily mean that the distance from the connecting rail to the opposite edge of the top plate is exactly the same. Instead, these distances may vary by up to 10% or 20%.

According to a further embodiment, the gas hob comprises an extraction unit for extracting flue gas arranged on or at least partly within the connection rail.

Thereby providing more working space for the user on the top plate. For example, the extraction unit is a downdraft extraction unit that removes the flue gas downward (i.e., into the area below the ceiling). According to an alternative embodiment, the extraction unit is not arranged on the connecting rail, but on the top plate.

According to a further embodiment, the extraction unit can be retracted into the connecting rail.

Thus, the extraction unit remains hidden when not in use.

According to further embodiments, the connection rail may be retractable into the top plate.

In this way, additional working space may be created when the gas cooktop is not in use. In addition, the surface of the top plate can be easily cleaned.

According to a further embodiment, the top plate and the connecting rail form a flat surface in their retracted state.

This allows providing a flat working surface formed by the top plate and the retracted connecting rail, which can then be used in other ways. For example, kitchen work may be performed on the top plate prior to cooking. After cooking, it can be easily cleaned because the user is not obstructed by the uneven top plate. A flat surface means in particular that the upper side of the connecting rail is flush with the roof plate in the retracted state.

According to a further embodiment, the gas cooktop comprises means configured to retract the connection rail into the top plate.

Such devices may include pneumatic systems and/or mechanical systems and/or electronic systems.

The same system can be configured to retract the extraction unit into the connection rail. Likewise, the same means can be used for driving the connecting rail out of the top plate and/or for driving the extraction unit out of the connecting rail. Alternatively, the connection rail and/or the extraction unit may be retracted or extended manually.

According to a further embodiment, the connection rail has at least one power socket for connecting an electrical device.

This allows the user to use the kitchen appliance on the top plate-even while cooking on the "other" side of the connecting rail.

According to a further embodiment, the top plate has, at least below each gas burner, a continuous flat surface on which the respective gas burner stands.

Also, this makes cleaning easier.

According to a further embodiment, the gas hob comprises a pan support for supporting a pan above each gas burner, at least one pan support being connected to at least one gas burner so as to form a unit configured to be lifted as a unit off the ceiling.

Having such a unit allows for easy assembly (or disassembly) when the gas hob is provided (or when the gas hob is no longer in use). "Pan" is understood to include any kind of cooking vessel, such as a pot, wok, etc. For example, the gas burner and the pan support may be connected by form fit, force fit, or adhesive fit.

According to a further embodiment, the at least one pan support is integrally formed with the at least one gas burner.

In this case, the pan support and the gas burner are (integrally) formed from one piece of material. For example, the pan support and the gas burner are cast as one (e.g. cast from cast iron).

"An" or "An" should not be construed as limited to only one element, but rather a plurality of elements may be provided unless otherwise specified.

Detailed Description

Fig. 1 shows a gas hob 1 in a perspective view. The gas hob 1 has a top plate 2. The top plate 2 may be rectangular in shape with short edges 5a, 5b and long edges 5c, 5 d. The edges 5a, 5b, 5c, 5d may limit the area of the gas hob 1.

The connecting rail 3 is arranged on the top plate 2 and, when viewed in plan view, passes through its center, for example. In particular, the opposite sides 4a, 4b, 4c, 4d of the connecting rail 3 each have the same distance from the opposite edges 5a, 5b, 5c, 5d of the top plate 2, which are parallel to the opposite sides 4a, 4b, 4c, 4d of the connecting rail 3.

The opposite sides 4c, 4d of the connecting rail 3 are formed, for example, as rectangular end faces 4c, 4d (and a rectangular cross section). The connecting rail 3 has its length direction in a direction perpendicular to the long edges 5c, 5d of the top plate 2 (the long sides 4a, 4b of the connecting rail 3 are parallel to the short sides 5a, 5b of the top plate 2). This allows placing gas burners 7 (as will be explained in more detail later) to the left and right of the connecting rail 3 when standing in front of the long side 5c (or 5 d) of the top plate 2 (i.e., when cooking). These sides 4a, 4b, 4c, 4d are preferably oriented perpendicular to the top plate 2 and thus extend upwardly therefrom. In embodiments where the joining rail 3 is configured to be retractable into the top plate 2 (see below), of course, this only applies to the extended state of the joining rail 3.

The connecting rail 3 has ports 6a, 6b to connect the gas burner 7 thereto. The ports 6a, 6b are arranged on different sides 4a, 4b, in particular on opposite sides, of the connection rail 3. Thus, at least one, preferably 2, 3 or more gas burners 7 may be arranged on either side of the connecting rail 3. For example, the port 6a is configured to supply fuel gas, while the port 6b supplies electric power to an igniter (not shown) of the gas burner 7. Or port 6b may also carry an electrical flame detection signal (e.g., from a thermocouple) to keep the gas regulating valve open.

In fig. 4, the gas burner 7 is disconnected and the ports 6a, 6b on the left-hand side of the connecting rail 3 are shown (except for the ports 6a, 6b seen on the right-hand side of fig. 1).

For example, each gas burner 7 is connected to one (gas) port 6a and two ports 6b (for electrical power) of the connection rail 3. The gas burners 7 are supplied with a fuel-gas-air mixture through respective ducts 8a via respective ports 6 a. Two ignition connectors 8b connect each gas burner 7 to the port 6 b. The ignition connector 8b is connected to an igniter (not shown) in each gas burner 7, which is configured to ignite the fuel-gas-air mixture.

In another embodiment, each gas burner 7 is provided with two struts 8b (instead of or in addition to the ignition connector, or the ignition connector may be integrated into the strut 8 b) and is fixedly connected at one end to the strut 8 b. At the other end, each strut 8b engages a respective hole or pocket 6b (not or not only a port in this case) formed inside the connecting rail 3. By the support 8b, the gas burner 7 can be prevented from being accidentally moved on the top plate 2, i.e., the gas burner 7 is fixed on the horizontal plane.

For example, the gas burners 7 each stand on a continuous flat surface 2a (see fig. 2) of the top plate 2. In fact, the entire surface of the top plate 2 may be formed as one continuous flat surface 2 a. When the user does not need the gas burners 7, they can be disconnected from the ports 6a, 6b to create more free space on the top plate 2.

Furthermore, each gas burner 7 may be associated with a pan support 9 to support a pan. The pan support 9 may be formed integrally with the gas burner 7 or may be a separate element which may be connected to the gas burner 7 to form therewith a unit which may be treated as one piece. The gas burners 7 may be of the same or different kind-the latter case being shown in fig. 1.

Furthermore, the gas hob 1 comprises for example an extraction unit 10, the extraction unit 10 being arranged partially (extended state, fig. 2) or completely (retracted state, fig. 1, 3 and 4) inside the connection rail 3. In fig. 1, the extraction unit 10 is retracted into the connection rail 3 (e.g. when the gas hob 1 is not in use). Fig. 2 shows the extraction unit 10 extending from the connection rail 3 (e.g. when cooking). In operation, the extraction unit 10 extracts smoke from the cooking area. The extraction unit 10 may be configured to remove gas from above the top plate 2 to a position below the top plate 2 (so-called downdraft extraction unit). The extraction unit 10 may be retracted into and extended from the connection rail 3, for example using an electric motor or a pneumatic system (not shown).

Fig. 3 shows the gas hob 1 with the connecting rail 3 in a retracted state, wherein the connecting rail 3 is fully retracted into the top plate 2. Preferably, the retracted connecting rail 3 is flush with the top plate 2. The retracted extraction unit 10 and the retracted connecting rail 3 form a substantially flat area on the top plate 2 in fig. 3.

When the user starts cooking, the connecting rail 3 may be extended upward from the top plate 2 (as indicated by arrow 11) using a driving means 12 (e.g. an electric motor) or by hand. The connection rail 3 may be extended upon user input, e.g. via a touch screen (not shown) controlling the drive means 12. Alternatively, the connection rail 3 may be automatically extended when a user switches on the standby mode of the modular gas cooker 1. Of course, the connecting rail 3 may be retracted, for example, by user input (e.g., via a touch screen) or by hand after cooking.

Returning to fig. 1, the connection rail 3 may comprise one or more sockets 13 for electrically connecting kitchen appliances or other electrical devices (i.e. sockets supplying electrical power, e.g. 220 volts). The sockets 13 may be arranged on different sides 4b, 4c of the connection rail 3. In the embodiment in which the connection rail 3 is configured to be retractable into the top plate 2, the receptacle 13 moves together with the connection rail 3, and is thus also hidden in the retracted state of the connection rail 3.

While the invention has been described in terms of preferred embodiments, it will be apparent to those skilled in the art that modifications are possible in all embodiments.
