Definitions

  • the present invention relates to an exhaust hood wherein the sensors are efficiently positioned to increase the automatic operation performance.
  • the exhaust hood provides the discharge of the water vapor and odor generated during the cooking process to the outside environment.
  • the exhaust hood generally comprises a suction motor, a suction channel and a suction surface.
  • the exhaust hood can be operated at different levels depending on the motor power in order to provide the discharge of the water vapor and odor generated during the cooking process to the outside environment. Said different levels can be selected by the user at appropriate stages according to the load of the cooking process.
  • the user operates the exhaust hood when required during the cooking process and selects the appropriate level.
  • the exhaust hood is operated automatically to increase user comfort and to determine the most accurate level.
  • sensors which monitor changes such as odor and temperature are used.
  • One of at least two temperature sensors on the exhaust hood measures the ambient temperature while the other temperature sensor detects whether the cooking device is operational or not from the temperature changes caused by the cooking process.
  • it can be determined whether the cooker under the exhaust hood is operational or not, from the relative change (differences) between the temperature information measured by said sensors. Accordingly, it is provided that the exhaust hood is activated, the level is increased, and when the thermal load disappears, the level is reduced and the exhaust hood is closed.
  • the position of the sensor which follows the ambient temperature, that is, the reference temperature, should be in a position which is suitable for measuring the ambient temperature, away from the hot air path caused by the cooking device load, at a point that is not affected by the heat caused by the cooking process.
  • the sensor measuring the ambient temperature is affected by the cooking device and the cooking process or external heat sources, no relative difference occurs between the sensor measuring the load temperature of the cooking device and the sensor measuring the ambient temperature, and the exhaust hood cannot perform its automatic operation function.
  • German Patent Application No. DE102006041581 an exhaust hood which is prevented from overheating and a control method are disclosed.
  • a smart exhaust hood comprising a control device is disclosed.
  • two negative temperature coefficient thermistors are used as sensors.
  • the thermistors are mounted directly onto the lower corners of the exhaust hood.
  • an exhaust hood comprising a temperature sensor placed on the outer surface thereof and measuring the ambient temperature and at least two temperature sensors placed on the suction surface, wherein the fan is controlled according to temperature difference based on the information received from the sensors.
  • an exhaust hood which is positioned above cooking devices such as cooker, oven, etc., comprising a body; a suction pipe; a fan which enables the air to be sucked and discharged to the outer environment; a guiding plate which is disposed on the lower surface of the body; an air suction duct; and one or more than one temperature sensor which measures the temperature of the air rising from the cooking device by heating up.
  • This document also discloses the temperature sensor which is mounted at the center of the air suction duct between the guiding plate and the front panel, which is positioned in the flow path of the air, and which is enabled to be affected from the air flow at maximum. Thus, incorrect measurement is prevented while the temperature sensor performs its automatic operating functions.
  • the aim of the present invention is the realization of an exhaust hood wherein the sensors are efficiently positioned to increase the automatic operation performance.
  • the exhaust hood realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims, comprises at least one first temperature sensor which detects the ambient temperature; at least two second temperature sensors which detect the temperature of the air rising from a cooking device such as countertop cooker, oven, etc. or a cooking vessel thereon and which are disposed on the flow path of the air sucked; and a control unit which enables the exhaust hood to automatically operate according to the information received from the first and second temperature sensors and which also enables the operation level to be automatically adjusted; and the first temperature sensor is disposed on the spacer between the suction channel and the casing.
  • the first temperature sensor which measures the ambient temperature, is placed in a more protected area to prevent the same from being suddenly affected by various physical elements in the external environment and to enable the same to measure the ambient temperature more effectively.
  • the room temperature can be more accurately monitored by measuring the temperature of a homogeneous region, which is affected by the environmental effects at the minimum level, by the first temperature sensor.
  • one and/or more than one temperature sensor is positioned on the spacer between the suction channel and the casing of the exhaust hood and the temperature of the homogeneous region between the casing and the suction channel is measured, thus by correctly detecting the relative difference between the second temperature sensor, which measures the cooking device load temperature, and the first temperature sensor, the automatic start, automatic level adjustment and automatic termination operations are provided.
  • the exhaust hood comprises a housing which is formed on the spacer and the first temperature sensor which is disposed into the housing.
  • the housing comprises a ceiling formed by shaping the spacer upwards, and an opening which is formed on the side of the housing facing the side wall of the casing and which allows the first temperature sensor to be placed and removed easily and quickly.
  • the exhaust hood comprises a first stage which is parallel to the base in the housing in which the first temperature is placed, and where the head of the first temperature sensor sits between the base and the first stage and a second stage which is parallel to the first stage and on which the body of the first temperature sensor sits.
  • the first and second stages enable the first temperature sensor to be easily placed into and removed from the housing and also enable the first temperature sensor to be positioned more securely in the housing so as to be prevented from moving.
  • the first and second stages are in the form of "U", which are formed such that the open parts thereof coincide with the opening.
  • the second stage comprises a step on which the body of the first temperature sensor sits.
  • the body of the first temperature sensor sits on the step from the bottom and the first temperature sensor is supported from the bottom of the body.
  • the first temperature sensor which is used for monitoring the ambient temperature
  • the first temperature sensor which is used for monitoring the ambient temperature
  • the heat generated by cooking, sunlight, a heater, air conditioner or ventilation operated in the room or air coming from the window is prevented from reaching the first temperature sensor directly.
  • a more accurate ambient temperature can be determined and the temperature change in the environment can be monitored. Consequently, the relative difference between the ambient temperature and the cooking device temperature is correctly detected, and the cooking processes done in different cooking device zones, different cooking device types, different cooking device power levels, different cooking vessels and different exhaust hood modes, are correctly detected while the fan motor is enabled to be automatically adjusted and terminated.
