Definitions

• thermostats
• the gas burning households control the gas outlets both of oven way and grill way, they have the devices of function of opening-closing operation, the otherwise, the devices have two gas outlets concerned on them. They are called double way or double outlet oven thermostats.
• the temperature of the first way can control and this way usually uses for oven ( K-1 ).
• the second way temperature can not control and usually uses for grill burner way.
• This new design prevents to the grill burner way is opened ( K-2 ) wrongly, while the oven burner way is closing ( K-1 ) or reverse act ; in this way, it provides safely closing.
• the classic double way oven thermostat if the spindle ( 1 ) is turning on the opened position ( fig. 1 -a, K-1 or K-2 ) from the closed position ( fig.1 -a, 0 ), the firstly, pushing the spindle by means of the spindle nail ( 1 -1 ) removes from the cover groove ( 2-1 ) and the spindle can turns left or right direction.
• This procedure is a specification according to the requested of EN 1106 Standard.
• the double way oven thermostat has the closed position "0" which does not permit gas flow from two gas way ( figure 1 -a ).
• the spindle nail ( 1 -1 ) is passed on the cover groove ( 2-1 ) at this position ( 0 ) and the spindle ( 1 ) can't turn 1-3 direction if the spindle is pushed.
• the classic double way oven thermostats which have not safety closing system ; the spindle push and turns with 1 -4 direction purpose of bringing the opened position ( figure 1 -a, K-1 ) from the closed position ( figure 1 -a, 0 ), it turns until K-2 position. In that case, the closed position didn't provide because of the gas flow from K-2 continuously and it is occurred dangerously situation.
• the new design thermostats ( with locked system ) have ; spindle ( 1 ), spindle nail ( 1 -1 ), cover ( 2 ) , cover groove ( 2-1 ), spring ( 3 ), stopper ( 4 ), body ( 5 ), internal conical ( 6 ), spring ( 7 ) and segment ( 8 ) ( figure 1 -b ).
• the spring ( 3 ) and stopper ( 4 ) are shown figure 1 -c.
• the stopper hole ( 4-1 ) is passed cylindrical hill on the cover ( 2-3 ) ( figure 1 -d ).
• the stopper's position is turned back origin point, as is seen direction of arrow by the spring ( 3 ), the spring is curved ( 3-1 , 3-2 ) for holding the stopper ( 4 ) and its shape is rectangular ( figure 1 -c ). It is shown on the figure 1 -d that, the cover has an groove ( 2-2 ) and an cylindrical hill for assembling the spring (3 ) and the stopper ( 4 ).
• the spindle ( 1 ) push and turns with arrow direction for moving the opened position ( K-1 ) to the closed position ( 0 ) ( figure 2 ). While the spindle nail ( 1-1 ) is at the closed position ( 0 ), it stands to the stopper ( 4 ) and can't turn more than this ( figures 3-a, 3-b, 3-c and 3-d ). At the figure 4-b is shown, the spindle nail ( 1 -1 ) push the stopper ( 4 ) with arrow direction and the spring ( 3 ) is positioned with an angle ( ⁇ ) by means of this force.
• the spindle nail ( 1 -1 ), stopper ( 4 ) and cover groove ( 2-1 ) positions are shown at the figure 3-c schematically.
• the spindle nail ( 1 -1 ) passes to the cover groove ( 2-1 ) and ensures 0 position ( figures 4-a, 4-b and 4-c ). In this way, passing the K-1 position to the K-2 position prevents directly.
• the spindle nail ( 1 -1 ) passes the cover groove ( 2-1 ) and states the closed position ( 0 ) from the second opened position ( K-2 ) ( figures 6-d and 6-e ).
• the double way oven thermostats While the spindle ( 1 ) states to the closed position ( 0 ) from two opened positions ( K-1 , K-2 ), the spring ( 3 ) and stopper ( 4 ) are added for the closed position ( 0 ) protection and they work as like a locking part. It is not possible to interfere in this locking system because of it is inside of the cover ( 2 ). In this way, the closing process is provided by safety.
