Definitions

  • the invention relates to a new gas control system enabling the gas taps used in domestic cooking appliances to be touch controlled by the user and to a gas tap having a male with an integrated cam that operates simultaneously with said system.
  • the tap according to the invention mainly consists of a gear driven by an internal servo motor, a transmission gear connected to said gear, and a male that operates simultaneously with said gear and thus controls gas passage.
  • Said male has an integrated cam system and enables the cam to move the shuttle inside the system; and with the movement of the shuttle, the safety valve inside the system is pushed. Thus, gas passage is allowed.
  • the gears provided in the newly designed tap provide a full transmission rate and transmit the angular movement provided by the motor to the male provided inside the tap, thereby allowing the male to rotate in the same angular rate (i.e. angle factor).
  • the application made by the company Electrolux Professional and numbered EP 2 273 678 A2 discloses a touch button for cooking appliances. As seen in Fig. 1 , the user can adjust any burning state desired by a single touch with his/her finger (F). However, this application covers only touch button, yet it discloses no gas control system or gas tap.
  • the application made by the company Electrolux Home Product Corporation and numbered WO 2006/128831 discloses a touch-sensitive control panel.
  • This panel comprises an outer plate (1) (i.e. upper part) with external contact areas (100) and a command assembly (2) (i.e. lower part) with an electronic circuit and components (3) thereof.
  • This application only discloses a touch-sensitive control panel.
  • this application also differs from the subject matter of the present invention and discloses no gas control system, gas tap or burner connected to said panel.
  • the control panel disclosed in our application is completely different from the one disclosed therein.
  • our invention directly relates to a new cam gas tap integrated with the male and to be operated in coordination with touch-sensitive gas control systems.
  • the application numbered US 2002/0045142 discloses a touch-controlled gas control system.
  • the invention comprises a burner (114) where burning occurs and which is composed of a microcontroller (101), two valves (112, 113), a gas line conduit (123), an igniter (118), a flame holder (117), as well as comprising various modules (igniter module, sensor module, etc.).
  • a microcontroller 101
  • two valves (112, 113
  • a gas line conduit 123
  • an igniter 118
  • a flame holder 117
  • this system is quite complicated and two valves (112, 113) within the system are only schematically displayed. In other words, no novelty or improvement on the valves has been made.
  • a new simple cam gas tap integrated with the male and operated in coordination with a gas control system has been developed.
  • the application owned by the company Orkli S. Coop. and numbered EP 1 909 029 discloses a safety electromagnetic gas tap.
  • an electromagnet (2) is provided in the safety gas tap and the operation of said electromagnet within the system is explained.
  • An electromagnet is used in the gas tap within this application.
  • all types of safety valves, apart from electromagnet can be used as a part of the integrated cam gas tap according to our invention.
  • a new integrated cam male design has been introduced in our invention in order for the shuttle to be pushed. Therefore, our invention is quite a different application from the former application.
  • the application owned by the company Mondragon Componentes S. Coop. and numbered EP 2 023 044 discloses a gas tap (3) comprising an electromagnet therein, as in the application numbered EP 1 909 029 .
  • the magnet used therein does not function as a part of the touch-sensitive control system, just as in the former application.
  • a tap with a new integrated cam male design has been introduced in our invention, as mentioned before.
  • the safety valve used in this tap is a safety valve type other than electromagnet and it is the same as the safety valve used today.
  • the object of the invention is to introduce a new touch-sensitive gas control system which allows touch control of the gas flow rate and which is applicable to smart phones, as well as introducing a new gas tap to operate in coordination with said system, within gas taps used in domestic cooking appliances.
  • Another object of the invention is to provide a cam gas tap integrated with the male and which allows the safety valve to be pushed with the rotational movement.
  • a preferred embodiment of the invention comprises at least one electronic card where the flow rate of the gas directed to the burners from gas taps in domestic cooking appliances and other commands are adjusted; at least one gas tap made of a cam integrated with the male directing the gas in desired flow rate to the burners; and at least one burner provided thereon with an igniter performing periodical ignition in accordance with the information sent by the system and with a flame holder allowing flame consistency.
  • cam gas tap directing the gas to the burners by synchronically operating with the gas control system comprises a body, a male with an integrated cam, a shuttle having a spring, and a safety valve as main components, as well as comprising a gearbox mounted on said body, a servo motor located in said gearbox, a spring, a drive gear, a transmission gear, and a gear system cover which is mounted on the gearbox in a way to cover it completely in order to prevent food residues and other external residues from getting in the system.
  • gas passage is controlled by the tap in maximum angles, between about 90° and 320°.
  • a spring that is located in the shuttle and that protects the system against mechanical overloading by damping when the cam is in pushing position as the shuttle starts to push the safety valve and holds the safety valve in the mounted position.
  • FIG. 1 the overall perspective view of a cooker (B) which is provided with touch-sensitive gas control system (A) according to the invention, and to which cam gas tap (1) according to the invention operating in coordination with said gas control system (A) is mounted, is given.
  • a cooker (B) which is provided with touch-sensitive gas control system (A) according to the invention, and to which cam gas tap (1) according to the invention operating in coordination with said gas control system (A) is mounted.
  • FIG. 2 another perspective view showing the interior of the same cooker (B) is given.
  • the gas exiting gas taps (1) is transferred to burners (2) by means of interconnecting pipes (7).
  • FIG. 4 schematic view of touch-sensitive gas control system (A) developed for domestic cookers or ovens, is given.
  • the system is composed of at least one gas tap (1) directing the gas, at least one burner (2) where the gas at a certain flow rate (Q) passing through this gas tap (1) is directed and where burning takes place, and at least one electronic card (10).
  • Q flow rate
  • electronic card 10
  • the commands issued to the electronic card (10) are processed and delivered to the servo motor (1.8).
  • the rotational movement driven by the servo motor (1.8) is transferred to the male (1.2) which is integrated with the cam (1.2.2) by means of the transmission gear (1.10), thereby allowing the rotation of the cam (1.2.2) and enabling the spring (1.3.1) positioned inside the shuttle (1.3) to be pushed, and the shuttle (1.3) camber (1.3.1) to press the safety valve (1.4).
  • gas passage is provided.
  • the gas directed to gas outlet (1.1.2) is transferred to the burner (2) where burning will take place by means of interconnecting pipes (7).
  • flame holder (2.2) detects it.
  • this information gets both to the electronic card (10) and to the safety valve (14).
  • the servo motor (1.8) stops as a result of the information coming to the electronic card (10) and the gears (1.9, 1.10) get to "0" reference position (closed position), thereby stopping the gas; moreover, the safety valve (1.4) stops gas flow. Therefore, gas leakage risks are minimized since double safety is provided.

  • a circular transmission gear (1.10) housing (1.7.5) and a servo motor (1.8) housing (1.7.4) are provided inside said gearbox (1.7) and the drive gear (1.9) is fixed on the servo motor (1.8) flange (1.8.2) by means of at least two connection screws (1.9.3).
  • the gear system cover (1.11) is mounted on said gearbox (1.7) by means of at least two connection screws (1.11.1). The reason for using this gear system cover (1.11) in the present invention is to prevent food residues and other external residues from getting in the gearbox (1.7), thereby avoiding any damage to the system.
