Description

TECHNICAL FIELD

The invention relates to a cooking appliance with a connecting element between a retractable control knob and a cock controlled by it.

STATE OF THE ART

In the gas-powered cooking appliances retractable buttons are mounted in the control unit by means of an outer shell in which they are positioned. In these embodiments, an opening for reaching the tap spindle is attached to the rear wall of the outer shell. The spindle enters through this opening and is mounted on the control knob. In the Turkish patent publication no. TR 2010 10611 such a construction is shown.

In today's state-of-the-art applications, the opening located in the center of the outer shell, where the gas tap and knob are placed together, is positioned with the tap and knob aligned in the same axis to allow the gas tap to move into the button can be embedded. In some implementations, where the gas pipes are not connected to the control unit, the axis of the spindle is displaced during the positioning operation because of the gas tap configuration and requires additional work for coaxial alignment,

Furthermore, retractable control buttons from the publication DE 199 51 422 A1 known.

From the publication EP 0 412 041 A2 is a gas tap known, which is connected by means of a telescopic arm with two articulated connections with the control knob. This telescopic arm with the two articulated connections allows a connection between the gas tap and the control knob in different types of gas cookers, each with a different trained distance between the control knob and the gas tap.

Finally, from the document GB 827,650 another cooking appliance known.

BRIEF DESCRIPTION OF THE INVENTION

The object of the invention is to simplify the alignment of the knob and the tap spindle in the cooking appliances with retractable buttons.

Another object of the invention is that the control knob in the cooking appliances, especially in the kitchen stoves, regardless of the position of the tap spindle can be operated.

In order to achieve the aforementioned object, the invented cooking appliance comprises an outer shell positioned in an operating unit; at least one retractable control knob movable within the outer shell in the direction of an operator reachable position; a gas tap controlled by a control knob; and a gas pipe connected at one end to the gas tap and at the other end to a burner.

The cooking appliance further comprises a motion transmitting member which is rotatably supported in an opening formed in the outer shell and having an arm coupled to the operation knob and a recess at the opposite end, and a hinge which is movably supported at one end within the recess and with the the other end is mounted in a tap spindle so that it transmits the movement of the motion transmitting member to the spindle. The fact that the connecting element has a movable joint, the joint moves within the recess by the movement of the spindle driving the joint and is at a suitable angle, even if the axis of the spindle is displaced during the assembly of the tap to Knopfachse.

As the hinge moves within the recess, this motion is not transmitted to the knob by the motion transmitting member.

The motion transmitting member transmits only the movements formed by the knob to the joint; the movements coming from the other direction are not transmitted. Thus, the knob is prevented from being bent, bent, or overstressed in any way. The fact that the joint can move freely within the recess, regardless of the cooking model ensures that the taps can be easily mounted on the device.

The connecting member includes a motion transmitting member having a recess in the form of a circular bearing. The connecting element further comprises a joint which has a spherical head, so that it moves in a circular manner within the recess. The motion transmission element directs the movements from the button to the joint and dampens the movements from the joint or from the tap spindle.

The fact that the recess and the joint have a spherical head, ensures that regardless of which side of the tap spindle is moved, the joint can move freely within the recess in all directions and positioned at an appropriate angle. Thus, the joint can rotate independently of the position of the spindle and then stands at a suitable angle to secure the easy installation of the cock.

The connecting element comprises the motion transmission element which has a recess which in each case contains a channel in its two opposite edges. The connecting element further comprises a joint with a spherical head having a through-going pin, so that both ends thereof remain outside so as to be stored in the channels belonging to the motion-transmitting element. When mounting the tap spindle, the spherical head joint moves within the recess, and thus the axial displacements of the tap spindle are not transmitted to the knob. However, the mutual movements, i. H. the operator generated movements of the button through the pin to the tap forwarded. During a rotary movement from the button side, the pin hangs on the channels and transmits the button movement to the joint.

The hinge is mounted in the motion transmitting member so that the axis of the pin is perpendicular to the axis of the arm. In one embodiment of the invention, the motion transmitting member each includes a channel in which a depth is provided in the direction of the arm axis, so as to allow the linear movement of the pin in the direction of the axis of the arm. For example, if the distance between the tap spindle and the knob is too short or if the tap spindle is displaced to the knob during assembly, the hinge enters the recess through the passage of the pin in the channels, approaches the arm and the length of the connector is reduced in the direction of the arm. Due to the depth, if the size of the spindle with respect to the assembly remains too short or too long, the distance between the knob and the spindle is compensated.

In one embodiment of the invention, the outer shell is mounted with a holding element on the movement-transmitting element comprising a recess as a connection part. Thus, it is prevented that with a formed in the outer shell
Opening mounted motion transfer element from the opening expires or protrudes more than the predetermined distance in the opening.

In one embodiment of the invention, the motion transmission element is fastened to the control knob as a snap connection (snap fit) and, in another embodiment, attached to the control knob as a clearance fit (loose fit). This ensures that the movements of the control knob are transmitted to the motion transmission element.
