Description

1 TARIFF AN ACTIVE COOLING SYSTEM FOR OVEN DOORS Technical Area The invention involves expelling hot air from inside the furnace door by creating an additional airflow within it. This relates to an active cooling system for the oven door. 5 More specifically; in an oven, when energy is applied to the hot air inside the oven door, the air by providing additional airflow from the inlet to the air outlet to evacuate the furnace, thus An active feature for oven doors ensures that the outer surface temperature of the door remains below the desired value. It is related to the cooling system. State of the Art 10 Ovens are appliances that heat or cook food items inside them. Cooking During this process, the high heat inside the oven causes the outer surface temperature of the oven door to also increase. When the oven door is closed and the oven is in operation, the oven's external surface temperature must be safe for users. The threshold temperature must not be exceeded. The outer surface temperature of the oven door must be at a certain level. One method of keeping the temperature below 15 is by creating an airflow inside the furnace door. Cooling is achieved by removing hot air. Oven door air cooling; cold outside air is drawn in from under the oven door and blown into the oven door. The oven is heated inside and rises upwards, and the air flow is provided by a radial fan. Passive cooling is achieved by blowing air through the vent on the door. High operating performance. in this mode, and especially by burning off fat and food residues inside the oven at very high temperatures, oven 20 In pyrolytic furnaces where cleaning is ensured, the furnace door outer surface temperature exceeds the limit value. This can happen. In these cases, passive cooling may be insufficient. Therefore, additional airflow is needed. by providing active cooling systems that can withstand high temperatures inside the oven door. There is a need. Document number CN208284607U states that the hot air forming between battery cells is called corona 25. This refers to a heat control system where the discharge is balanced by the ion wind generated after the discharge. However, the system for controlling the temperature of the battery cells mentioned here involves the air inside the furnace door. It does not offer a solution to the issue of cooling and evacuation. 2 Document number WO2018104000A1 describes oven door air cooling connected to a ventilation fan. The system in question is described. In this system, cooling takes place in the oven outside the oven door. It depends on the fan motor located in the area. A high-power fan motor is needed for cooling the oven door. Its use necessitates additional space in the design and causes extra noise in the operating oven. The application in question concerns oven 5, which provides active cooling through a system integrated into the oven door. It does not offer a solution to the door cooling issue. In conclusion, in order to solve the problems mentioned above, a high-rise structure is placed inside the oven door. This has created a need for active cooling systems that can withstand high temperatures.

Corona discharge involves two electrodes to which voltage has been applied. the electric field formed between them exceeds the breakdown voltage of the air molecules around them These are short-term discharges that occur as a result. During a corona discharge, ions are produced and electricity is emitted. It is accelerated by the field. As ionized air moves from one electrode to another, the neutral electrode... It collides with air molecules, and this momentum transfer causes a mass of air currents. 15 This air current, resulting from corona discharge, is called an ion wind.
