Definitions

  • the present invention relates to an oven wherein sensors perform effective detection and measurement.
  • the temperature of the cooking chamber during the operation of the oven is much higher than the temperature of the ambient environment wherein the oven is located.
  • the temperature of the cooking chamber is quite high. Therefore, particularly the sensors for humidity, gas etc. having much lower operational temperatures than the high temperatures of the cooking chamber cannot be used inside the cooking chambers.
  • the use of sensors in ovens is very limited since the operational temperature values of the sensors are not suited for oven operational conditions. For example, since the existing humidity sensors are damaged by heat and humidity, they cannot be emplaced in the oven for detecting and controlling the humidity value of the high temperature air in the oven.
  • the gases that are generated in the cooking chamber are mixed with the cold air from the outer environment in a ventilation channel and is delivered to the gas and/or humidity sensor after the temperature is lowered.
  • the gases will change depending on the features of the exterior environment, the gases in the cooking chamber cannot be measured accurately. Therefore, the data received from the sensor does not exactly reflect the conditions inside the oven.
  • the object of the present invention is the realization of an oven comprising humidity, gas etc. sensors positioned at a place such that they will not be affected by the high temperatures in the cooking chamber and will make reliable measurements.
  • the oven realized in order to fulfill the objectives of the present invention, described in the first claim and dependent claims thereof, comprises a sensor chamber that opens directly to the cooking region and a ventilation channel wherein this sensor chamber is disposed, cooling this sensor chamber.
  • the sensor chamber and the sensors should preferably be automatically isolated in order to protect the sensors.
  • Figure 1 - is the perspective view of an oven.
  • Figure 2 - is the schematic side view of the oven.
  • Figure 3 - is the perspective view of the sensor chamber in an embodiment of the present invention.
  • Figure 4 - is the perspective view of the sensor chamber in another embodiment of the present invention.
  • Figure 5 - is the schematic front view of the oven in an embodiment of the present invention.
  • the oven (1) of the present invention comprises a body (2), a cooking chamber (4) situated inside the body (2), wherein the items to be cooked are empkced, a door (5) separating the cooking chamber (4) from the exterior environment, providing access of the user into the cooking chamber (4), a Ian (9) providing air circulation around the cooking chamber (4), a ventilation channel (6) situated between the body (2) and the cooking chamber (4), partly encircling the cooking chamber (4), wherein the Ian (9) is arranged, providing to aspirate air from the door (5) or the exterior environment and after the aspirated air is circulated in the cooking chamber (4) discharging into the exterior environment again, a sensor (7) that detects and measures the parameters like gas, humidity etc.
  • the oven (1) furthermore comprises a suction line (11) having an air inlet (10) for the entry of the air aspirated from the exterior environment or the door (5), a discharge line (13) having an air outlet (12) through which the air passing from the suction line (11) is discharged to the exterior environment, providing the flow of air discharged to the exterior environment and a separator (14) that separates the suction line (11) from the discharge line (13).
  • the sensor chamber (7) extends in the ventilation channel (6) between the suction line (11) and the discharge line (13), intersecting through the separator (14).
  • the air aspirated from the exterior environment or the door (5) that is cooler than the cooking chamber (4) enters from the air inlet (10), flows along the suction line (11) and passes through the discharge line (13) by means of the Ian (9) and is discharged from the air outlet (12) to the exterior environment.
  • the sensor chamber (8) is cooled by the air circulated in the ventilation channel (6) through the suction and the discharge lines (11 and 13). Cooling the outer wall of the sensor chamber (8), particularly the upper portion of the sensor chamber (8) wherein the sensor (7) is positioned, by the air circulated in the discharge line (13) of the ventilation channel (6), provides the sensor (7) not to be affected by the temperatures higher than its operational conditions.
  • the portion of the sensor chamber (8) opening into the cooking chamber (4) has the value of 280° C
  • its portion in the ventilation channel (6) that corresponds particularly to the discharge line (13) has a colder temperature value.
  • the sensor (7) is situated in the upper portion of the sensor chamber (8) extending into the discharge line (13).
  • the sensor chamber (8) comprises one or more fins (15) situated on its outer wall, extending into the ventilation channel (6), increasing its surlace area in contact with air ( Figure 3). Consequently, the air circulating in the ventilation channel (6) impinges on these fins (15) and provides to cool the sensor chamber (8) and the sensor (7) situated in the sensor chamber (8) and not to be affected by the high temperature in the cooking chamber (4).
  • the fins (15) have a helical shape ( Figure 4).
  • the oven (1) comprises a shutter (16) disposed in the sensor chamber (8) that opens or closes depending on the temperature of the cooking chamber (4).
  • the shutter (16) is closed, preventing the hot gases to reach the sensor (7), providing the sensor (7) not to be affected by the high temperature in the cooking chamber (4).
  • the shutter (16) is opened, allowing the gases in the cooking chamber (4) to reach the sensor (7), providing the sensor (7) to carry out its function properly.
  • the shutter (16) closes the sensor chamber (8) in high temperatures, providing to isolate the sensor (7) situated in the sensor chamber (8) and thus protects the sensor (7) from high temperatures.
  • the oven (1) comprises a chimney (3) that extends from the cooking chamber (4) to the ventilation channel (6).
  • the sensor chamber (8) is situated in the ventilation channel (6) between the chimney (3) and the fin (9).
  • the chimney (3) is between the sensor chamber (8) and the Ian (9).
  • the sensor chamber (8) is preferably made of metal; it can also be produced of a plastic material resistant to high temperatures.
  • the sensors (7) that detect and measure parameters such as gas amount, humidity etc. inside the cooking chamber (4) with high operational temperatures are provided to be situated in the oven (1) in a position that will allow making the accurate detection and measurement without being affected by the high temperature. Furthermore, cost advantage is incurred since the use of high cost sensors with increased resistance to heat is deemed unnecessary.
