Definitions

  • the invention relates to a spring and pin which will be used for absorbing impacts or pressures that are likely to occur in the electromagnet in case the tap shaft is fully pressed within gas taps having electromagnet which are used in domestic cooking appliances.
  • the spring according to the invention can be located in different places within the body, wherein it is characterized by being concentric with other springs within the system, and by protecting the system by absorbing excessive loads applied from outside starting from the position when the electromagnet is fully pressed.
  • Gas taps having an electromagnet which are used today generally consist of a body having gas passageways; a plug regulating gas passageways; a handle enabling the user to locate gas passageways; an electromagnet for opening/closing gas passageway; together with a pin transferring the movement from the handle to the electromagnet; a union fixing the electromagnet in the housing thereof within the tap; and a cover protecting the tap against external factors.
  • pressure is applied when the user presses the handle too hard, which, in turn, creates impact effect in the electromagnet and may prevent the system from operating safely.
  • a third spring in addition to the other springs, one of which enables the o-ring inside the plug to remain in the corresponding housing and the handle to permanently remain inside the cover, and the other one of which allows the gasket to move, will be used; and thanks to this third spring, the system will be protected against excessive load.
  • a new handle and pin designed in a way suitable for the system are used, instead of the conventional pin and handle used in the current state, according to what place the spring will be located in the system according to the invention.
  • a gas flow tap which is made of an electromagnet comprising a shaft moveable axially in a first direction and a regulation element moveable in a second direction, and which is used for gas burners.
  • said tap is designed for built-in cookers; wherein mechanical problems may be experienced depending on the pressing force applied by the user on the handle due to the angle between the handle and electromagnet; and also the contractions likely to occur in the tap cannot be prevented since there is no absorbing part provided therein for lowering the effect of excessive load applied by the user on the system.
  • the object of the invention is to use an impact-absorbing spring for protecting the system against the excessive load by the user within gas taps having an electromagnet which are used in domestic cooking appliances.
  • Another object of the invention is that the weight of said impact-absorbing spring is more than the other springs in the system in order for the former to protect the system by being activated when there is excessive load on the system and the other springs cannot operate properly.
  • said impact-absorbing spring can be located at any end of the pin provided in the body or in the housing which extends to one end of the pin, or in the handle housing, such that it will be concentric to the other springs within the system; wherein the design of the pin and handle used within the system change in accordance with the location of said spring.
  • Fig. 1 the overall perspective view of the gas taps having an electromagnet of the state of the art is given.
  • Figs. 2 and 3 the cross-sectional views of said gas taps of the state of the art are given. Accordingly, the gas (2) getting in the system from the gas inlet (1.1.1) way in the body (1.1) first reaches to the area where the electromagnet (1.3) is provided, and upon rotation of the conventional handle (1.8) by the user, the conventional pin (1.4) located inside the plug (1.2) moves and the electromagnet (1.3) is pushed, and thus enabling the gas (2) to reach to the burner.
  • the impact-absorbing spring (1.12) used in the system according to the invention is suitable for all gas tap types having said electromagnet ; and in case of excessive load, said spring stretches and protects the electromagnet (1.3) against the impact and pressure applied by the user, thereby making the service life of gas taps longer.
  • the views of conventional handle (1.8) and conventional pin (1.4) used in the gas taps having electromagnet are given in Figs.
  • the impact-absorbing spring (1.12) can be located in four different ways inside the body (1.1); i.e. in housing(1.9.1) of handle according to the invention, in end portion(1.5.1) of the pin according to the invention(1.5) according to the invention, in alternative pin housing (1.6.1), and in the other alternative pin housing (1.7.1); wherein the object is achieved in all of these four states.
  • Said impact-absorbing spring (1.12) according to the invention is heavier than the gasket spring(1.10.1) and O-ring fixing spring (1.11.1) in the tap, wherein it is about 1500 g. The reason for that is to allow it to stretch easily in case of pressure or excessive load. Further, the length of said the impact-absorbing spring (1.12), shown in Fig. 6 , is adjusted where will be placed of outside 1-3 mm from the housing (1.9.1) of the handle according to the invention or alternative pin housing (1.6.1) and the other alternative pin housing (1.7.1), where it will be located, according to the invention. Accordingly, the impact-absorbing spring thread (1.12.1) number of said the impact-absorbing spring (1.12) is at least 3, while the outer diameter (1.12.1.1) thereof is between 1.5 and 4 mm.
  • the distance (c) of the segment (1.15) provided on the conventional handle(1.8) handle according to the invention(1.9) to the cover (1.14) is smaller than the sum of the distance (a) of the impact-absorbing spring (1.12) which will be placed of outside from the other alternative pin housing (1.7.1) or end portion of pin according to the invention (1.5.1), to the electromagnet (1.3); or the distance of the conventional pin(1.4) alternative pin(1.6) to the electromagnet (1.3), and of distance (b) of the impact-absorbing spring (1.12 will be placed of outside housing (1.9.1) of the handle according to the invention or alternative pin housing(1.6.1) the other alternative pin housing( 1.7.1), or end portion of the pin according to the invention (1.5.1).
  • the invention is suitable for being used in all taps having electromagnet which are used in domestic cooking appliances.
