Definitions

  • the present invention relates to a system for dispersing chemical agents in ovens, in particular professional ovens for fine cuisine and hotels, using a chemical agent in a solid format without recirculation in the oven.
  • the self-cleaning system without recirculation is generally made up of one or more sprinklers of chemical agents in the upper portion of the cooking chamber.
  • the chemical agent sprayed is usually liquid, and it is carried to the area of the sprinkler by means of a pump.
  • the sprinkler sprays the entire cooking chamber, usually in a rotating manner. During this process, a convection fan is turned off in order to prevent the flow of the chemical agent from being deviated by the air flow.
  • the chemical agent is left to rest for a certain period of time under ideal temperature and moisture conditions in order for the desired effect to be produced.
  • the rinsing will be performed by means of a solenoid valve which injects tap water into the sprinkler or other sprinklers/sprayers distributed in the cooking chamber.
  • a reduced version of this cleaning system must be made up of, at least, the following electromechanical elements:
  • the self-cleaning system with recirculation it is usually made up of one or several outlet points of the liquid recirculated in the upper portion of the cooking chamber.
  • solid chemical agent is used, in tablet or powder form, which is deposited in the cooking chamber for the dissolving thereof.
  • liquid chemical agent can also be used. In that case, the liquid chemical agent is carried to the inside of the oven with an additional pump.
  • a solenoid valve is responsible for filling a collector, and once the chemical agent has been diluted with this water, a pump is responsible for carrying the mixture to the recirculation outlet, which is dispersed by mechanical elements, and distributed throughout all the area for cooking and for generating heat by means of the very convection fan of the oven.
  • This process of recirculating the mixture continues for a certain period of time under ideal temperature and moisture conditions for the desired effect to be produced.
  • a convection fan is generally operating in order to spread it throughout the cooking chamber and the heat-generating area.
  • the emptying of the collector is performed, and it is once again filled with tap water through a solenoid valve. Once this is done, the water is recirculated in order to rinse the oven. It is probable that the emptying and rinsing process must be repeated several times in order to ensure optimal rinsing.
  • a reduced version of this cleaning system must be made up, at least, of the following electromechanical elements:
  • an objective of the present invention is to provide a dispersion system for ovens that is cheaper than the current dispersion systems.
  • the dispersion system of the invention resolves the aforementioned drawbacks and has other advantages which are described below.
  • the system for dispersing chemical agents in ovens according to the present invention comprises:
  • said tube for injecting water is actuated by means of a solenoid valve for the dissolving of the water with the chemical agent and for the rinsing of the mixture of water and chemical agent.
  • a solenoid valve for the dissolving of the water with the chemical agent and for the rinsing of the mixture of water and chemical agent.
  • said fan is a convection fan, particularly, the convection fan of the very oven.
  • said chemical agent is placed in at least one vessel, forming a collector wherein the water is accumulated in order to be mixed with the chemical agent.
  • said at least one vessel comprises upper holes for the inlet of water and an overflow hole connected to a duct, which leads the mixture of water and chemical agent from at least one vessel to the fan, dispersing the mixture in the heat-generating area and the cooking area of the oven. It also comprises a border which prevents the movement of the chemical agent.
  • the tube for injecting water preferably comprises a deflector for diverting the water in order to reach all the heat-generating and cooking area of the oven, and it also comprises an outlet hole located between the heat-generating area and the cooking area of the oven.
  • the cooking area of the oven comprises an opening located in the upper portion thereof which receives the air flow generated by said fan.
  • the present invention describes a system for dispersing chemical agents in a solid format without recirculation in an oven.
  • chemical agents can have different purposes, such as the cleaning of the oven, decalcification, polishing, anti-rust treatments, etc.
  • the chemical agent 1, preferably in tablet form, is positioned inside the oven, in one or several vessels 2, such that the tablet 1 fits therein.
  • This vessel 2 has a border 3 which prevents the tablet 1 from coming out due to vibrations or turbulence in the air.
  • This border 3 furthermore, acts to accumulate water in the bottom of the vessel 2.
  • a tube 4 for injecting water is arranged, connected to a solenoid valve 5, which will be activated in a pulsed manner when the tablet 1 needs to be dissolved.
  • the activation of the solenoid valve 5 is performed periodically during a time W L every T seconds.
  • this vessel 2 is closed, such that it acts as a collector 6.
  • the solenoid valve When the solenoid valve is activated, the water comes out of the tube 4 and a portion thereof falls onto the tablet 1 through upper holes 7 of the vessel 2.
  • the water dilutes the tablet 1 in a controlled manner, the dilution staying in the collector 6 of the bottom of the vessel 2.
  • the excess liquid with the mixture of water and chemical agent that is in the collector 6 overflows from a hole 8 which is carried through a duct 9 to a convection fan 10.
  • the convection fan 10 when it rotates in both directions of rotation, disperses the mixture of water and chemical agent throughout all the heat-generating area 11 and the cooking area 12 of the oven.
  • the chemical agent is left to rest for a certain period of time under ideal temperature and moisture conditions in order for the desired effect to be produced on the heat-generating area 11 and the cooking area 12 of the oven.
  • the rinsing is performed by activating the solenoid valve 5, which injects tap water to the upper area of the oven through the tube 4.
  • the outlet hole 13 of this tube 4 is in the border between the heat-generating area 11 and the cooking area 12.
  • the activation of the solenoid valve is performed periodically during a time W A every T seconds, being W A ⁇ W L and W A ⁇ T.
  • W A ⁇ W L and W A ⁇ T the solenoid valve is activated, the jet of water is directed at a deflector 14 strategically placed so the water can reach all the heat-generating 11 and cooking 12 area of the oven.
  • the air generated by the convection fan 10 is directed to the upper portion of the cooking area 12 through an opening 15 close to the outlet hole 13 for water and the deflector 14. This air flow helps the water to be distributed throughout all the heat-generating 11 and cooking 12 area of the oven, performing the rinsing in an effective manner.
