[0001] The present invention relates to a cooking device comprising an improved ignition
switch.
[0002] In the state of the art, cooking devices have at least one burner group whereon the
product to be cooked/heated is placed. When the user places the cooking vessel on
any one of the burner groups, he/she controls the relevant burner group with the knobs
which are provided on the panel, each corresponding to a burner group.
[0003] In the cooking device, for example in a cooker, it is known to use an ignition switch
connected to the knob to ignite each burner group. By means of said ignition system
which eliminates the need for an igniter or similar component to ignite the existing
gas, the user is only required to press and turn the knob. On the other hand, using
an ignition switch for each knob increases the cost. Water, foodstuff residues or
detergent residues leaking into the base of the tap while the user is cooking or cleaning
may also cause said ignition switches to jam over time and perform constant ignition.
[0004] Gaskets and similar additional components are needed to protect said ignition switches
from external factors. Moreover, switches which are not properly installed by the
operator during the production process may become dislodged over time and perform
constant ignition.
[0005] In the state of the art Turkish Patent No.
TR 2014/05531, a cooking device is disclosed, comprising a lower casing; a burner table which is
disposed on the lower casing and which has burners for heating and/or cooking; a plurality
of taps which enable the gas to be burned to be transferred to the burners on the
burner table in the amount determined by the user; and a gas pipe which carries the
gas to be burned from the mains to the taps.
[0006] The aim of present invention is the realization of a cooking device comprising an
ignition group wherein instead of using multiple ignition switches, only one is used
and problems such as water leaks and possible dislodging of the switches are eliminated.
[0007] The cooking device of the present invention comprises a body; a burner plate having
a plurality of burner groups thereon for heating and/or cooking; a plurality of taps
which provide the transfer of the gas to be burned in the burner group in the amount
determined by the user; a knob which is connected to each tap and which can be moved
by the user; and an ignition switch which actuates the ignition of the burner group.
Since only one ignition switch is used, advantages in terms of both labor and cost
are provided.
[0008] The cooking device of the present invention comprises an actuation member which is
positioned so as to move in a channel and which contacts the ignition switch with
the movement received from the knob so as to enable the ignition switch to be actuated.
By means of the actuation member, a mechanical and durable actuation function can
be performed. Instead of the switch structure which can be provided at the base of
the tap, only a mechanical spring structure is used in order to prevent the problems
of water leakage and the switch dislodging.
[0009] The cooking device of the present invention comprises an actuation member which is
positioned so as to move in a channel extending along each knob and which does not
actuate the ignition switch in the first position and which, in the second position,
contacts and actuates the ignition switch with the movement received from the knob.
The actuation member comprises an actuation protrusion which aligns with each knob
with the pressure of the spring when the cooking device is not yet in use. While the
user presses and turns the desired knob, the actuation protrusion shifts from the
first position to the second position. At this time, the ignition switch is enabled
to be actuated.
[0010] The cooking device of the present invention comprises a spring which is connected
to the actuation member such that the actuation member can return to the first position
after shifting to the second position as the user moves the knob. Moreover, the relevant
spring is positioned on the actuation member such that one end thereof bears against
the channel. Thus, when the user stops gripping the knob, the actuation member under
the pressure of the spring is released and moves in the opposite direction in the
channel, shifting back to the first position.
[0011] The cooking device of the present invention comprises the knob comprising a knob
base which is connected to a knob shaft on each tap and which contacts and pushes
the actuation member with the pushing movement of the user. When the user presses
the knob, the knob base contacts the actuation member. The knob base may be flat or
have protruding or curved parts.
[0012] The cooking device of the present invention comprises a plurality of actuation protrusions
which are provided on the actuation member, corresponding to each knob and which enable
the actuation member to be moved in the channel with the movement received from the
knob. The actuation protrusion which is an extension of the actuation member is positioned
to be opposite to each knob. When said actuation protrusion is pushed by the knob
base, the actuation member presses against the spring in the channel.
[0013] The cooking device of the present invention comprises an ignition switch which is
positioned flush with the channel and which is suitable to be actuated by the actuation
end of the actuation member extending out of the channel with the movement received
from the knob. By using only one ignition switch, ignition can be performed at all
burner groups. By means of this development, the ignition switch is positioned away
from the knobs, rather than directly in the vicinity of the knob.
[0014] The cooking device of the present invention comprises a series of actuation protrusions
which extend from the opening on the channel to each knob and which are shaped in
the form of a V so as to have a bent part. By means of said structure of the actuation
protrusion, the actuation member can easily slide in the channel when the knob is
pressed in a perpendicular direction.
[0015] The cooking device of the present invention comprises the actuation member comprising
the actuation protrusion having a sliding surface inclined between 30° and 60° relative
to the longitudinal axis of the channel. By means of the actuation protrusion which
is inclined in this optimum range, the actuation member is enabled to move smoothly
in the channel.
[0016] The cooking device of the present invention comprises a second type of actuation
protrusion which extends on the actuation member corresponding to each knob and which
is inclined between 30° and 60° relative to the longitudinal axis of the channel.
Said second type of actuation protrusion extends from the actuation member in an inclined
direction towards the knob.
[0017] The actuation member of the present invention may be manufactured from a metal wire
or may have a width so as to extend to the lateral walls in the channel.

[0020] The cooking device (100) of the present invention comprises a body (101); a burner
plate (102) having a plurality of burner groups (103) thereon for heating and/or cooking;
a plurality of taps (3) which provide the transfer of the gas to be burned in the
burner group (103) in the amount determined by the user; a knob (2) which is connected
to each tap (3) and which can be moved by the user; and an ignition switch (4) which
actuates the ignition of the burner group (103). Advantageously, in the cooking device
(100), there is only a single ignition switch (4) which is suitable for mechanical
actuation. Thus, the need for using an ignition switch (4) for each tap (3) is eliminated
and problems such as possible incorrect placement and grouping are prevented during
the assembly.
[0021] The cooking device (100) of the present invention comprises an actuation member (12)
which is positioned so as to move in a channel (11) and which contacts the ignition
switch (4) with the movement received from the knob (2) so as to enable the ignition
switch (4) to be actuated. Figure 1 shows a knob (2) which is not pressed by the user,
and Figure 3 shows the actuation member (12) which is activated as said knob (2) is
pressed. Accordingly, the actuation member (12) of the present invention is suitable
to move in the channel (11) extending along each knob (2) and does not actuate the
ignition switch (4) when in the first position, and, when in the second position,
contacts and actuates the ignition switch (4) with the movement received from the
knob (2). Thus, the need for using an ignition switch (4) in each tap (3) in the state
of the art is eliminated and a mechanically actuated system is realized. Consequently,
by not using an ignition switch (4) in each tap (3) in the gas tap group (1), the
cost is reduced and technical problems such as possible non-ignition or jamming are
prevented.
[0022] In an embodiment of the present invention, the cooking device (100) of the present
invention comprises a spring (13) which is connected to the actuation member (12)
such that the actuation member (12) can return to the first position after shifting
to the second position as the user moves the knob (2). In another embodiment of the
present invention, said spring (13) is positioned on the actuation member (12) as
shown in Figure 8, and one end thereof bears against the channel (11). Thus, while
moving in the channel (11), the actuation member (12) pressed by the knob (2) compresses
said spring (13) in the channel (11). The energy accumulated by compressing said spring
(13) is released when the user releases the knob (2) and enables the actuation member
(12) to shift to the first position as shown in Figure 1.
[0023] When the cooking device (100) of the present invention is in use, the user first
grips and presses the hand-held gripping part (21) on the knob (2), then rotates the
same to transfer as much gas as desired from the tap (3). During this pressing process,
the knob (2) pushes the actuation member (12) and the actuation function for all burner
groups (103) is performed by the ignition switch (4) and the burning process begins
in the burner group (103) to which gas is supplied.
[0024] In an embodiment of the present invention, the knob (2) is connected to a cylindrically
protruding knob shaft (22) which is provided on each tap (3). Said knobs (2) have
a knob base (23) which contacts and pushes the actuation member (12) with the pushing
movement of the user. As shown in detail in Figures 5 and 6, when the knob (2) is
pushed towards the cooking device (100) by the user, the knob base (23) of the knob
(2) contacts the actuation protrusion (121) of the actuation member (12) and enables
the actuation member (12) to shift to the second position. Here, the actuation end
(122) of the actuation member (12) in the second position extending out of the channel
(11) contacts the ignition switch (4) or enters a certain area in the ignition switch
(4), and actuates the ignition switch (4) to initiate ignition to burn the delivered
gas.
[0025] In an embodiment of the present invention, the cooking device (100) of the present
invention comprises a plurality of actuation protrusions (121) which are provided
on the actuation member (12), corresponding to each knob (2) and which enable the
actuation member (12) to be moved in the channel (11) with the movement received from
the knob (2). Referring to Figure 1, the actuation member (12) comprises actuation
protrusions (121) as many as the number of knobs (2) in the cooking device (100),
and each actuation protrusion (121) is configured in a similar shape and form.
[0026] In an embodiment of the present invention, the ignition switch (4) is positioned
in the same longitudinal axis direction, suitable for being actuated by the actuation
end (122) of the actuation member (12) extending out of the channel (11). By means
of said actuation end (122), the ignition switch (4) detects that the actuation member
(12) is in the second position and starts the ignition process. Said ignition switch
(4) may be a switch suitable for use in cookers in general and may be connected with
a plurality of fixing members on an extension plate of the channel (11).
[0027] The actuation member (12) of the present invention comprises a series of actuation
protrusions (121) which extend from the opening on the channel (11) to each knob (2)
and which are shaped in the form of a V so as to have a bent part (124). Said part
(124) is composed of an inclined part relative to the actuation member (12) and another
part extending perpendicularly relative to said actuation member (12). The bent part
(124) forms an angle of approximately 45° within itself. Here, by means of the inclination
of the actuation protrusion (121), the actuation member (12) is enabled to make a
sliding movement in the channel (11). In an embodiment of the present invention, said
actuation member (12) comprises the actuation protrusion (121) having a sliding surface
(125) inclined between 30° and 60° relative to the longitudinal axis of the channel
(11). As shown in Figure 4, said angle can be selected as 45°.
[0028] In an embodiment of the present invention, the cooking device (100) of the present
invention comprises a second type of actuation protrusion (1211) which extends on
the actuation member (12) corresponding to each knob (2) and which is inclined between
30° and 60° relative to the longitudinal axis of the channel (11). Again, just like
the actuation protrusion (121), there is a second type of actuation protrusion (1211)
corresponding to each knob (2). As shown in Figure 11, the actuation member (12) in
the first position comprises the second type of actuation protrusions (1211) in the
form of approximately 45° protrusions. When the knob (2) is pressed, the actuation
member (12) moves by means of the inclined second type actuation protrusion (1211)
and actuates the ignition switch (4). The second type of actuation protrusion (1211)
which is obtained by using less material ensures that the system operates mechanically
in a smooth manner.
[0029] In an embodiment of the present invention, the actuation member (12) can be manufactured
from metal wire or can be configured to have a larger transversal cross-section. Said
actuation member (12) may also be a wire rod manufactured from copper or metal by
being wound in the form of a coil.
[0030] As shown in Figure 14, a gas cooker can be used as the cooking device (100) of the
present invention. There are preferably four burner groups (103) of different sizes
