Definitions

  • the present invention relates to an oven wherein the steam cooking process is automatically performed.
  • the user In order to perform steam cooking in ovens where steam cooking can be performed, the user must check the oven preheating time in the user manual. When the oven preheating time is reached, the user fills the water tank with the required amount and places the same in position. In this embodiment, the user is required to control and perform parameters such as the cooking time, the amount of water to be put into the tank by constantly checking the user manual.
  • the water tank is placed on the bottom of the oven. In this case, since the oven door is opened, it is exposed to heat and causes energy loss.
  • the shape memory spring is used to securely lock the oven door during the cleaning process at high temperatures (400° - 480°C).
  • the aim of the present invention is the realization of an oven wherein the steam cooking process is automatically performed.
  • the oven realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body wherein the foodstuffs to be cooked are placed; a casing which surrounds the body; a water tank which is disposed between the casing and the body and which is filled by the user; a pipe with one end opening into the water tank and the other opening into the body and which provides the transfer of water vapor into the body; a valve which is disposed on the pipe and which provides the delivery of the water vapor into the body in a controlled manner; and a shape memory spring mechanism which enables the valve to open/closed according to the temperature in the body.
  • the steam cooking process is automatically performed without requiring the intervention of the user. Since the user does not open the oven door, both safe use and energy savings are provided.
  • the oven comprises a spacer placed on the outer wall of the body.
  • the body heat is transferred to the shape memory spring mechanism by conduction and the valve is opened or closed at the right temperature and time.
  • the spacer is manufactured from sheet metal.
  • the spacer is L-shaped and has a first arm on the body outer wall which contacts the ceiling and a second arm which contacts the body side wall.
  • an effective heat transfer is provided by means of a mechanical connection.
  • the first arm has one short and two long sides in contact with the ceiling on the outer wall of the body, and the spacer comprises a chamber between the first arm and the ceiling.
  • the gap formed between the first arm and the ceiling as a result of only the edges of the first arm contacting the ceiling is defined as a chamber filled with ambient air.
  • the heat accumulated in said chamber is transferred to the shape memory spring mechanism.
  • the valve opens automatically when the desired temperature is reached so as to ensure the performance of the steam cooking process and when the desired temperature is reached, the valve is closed and the steam cooking process is terminated.
  • the oven (1) comprises a body (2) wherein the foodstuffs to be cooked are placed; a casing which surrounds the body (2); a water tank (11) which is disposed between the casing and the body (2) and which is filled with water; a pipe (5) with one end opening into the water tank (11) and the other opening into the body (2) and which provides the transfer of water vapor into the body (2); a valve (3) which is disposed on the pipe (5) and which provides the delivery of the water vapor into the body (2) in a controlled manner; and a shape memory spring mechanism (4) which enables the valve (3) to open/closed according to the temperature in the body (2) ( Figure 1 ).
  • the steam cooking process is automatically performed without requiring the intervention of the user. Since the user does not open the oven (1) door, both safe use and energy savings are provided.
  • the oven comprises a spacer (6) which is placed on the outer wall of the body (2) and whereon the shape memory spring mechanism (4) is disposed.
  • the body (2) heat is transferred to the shape memory spring mechanism (4) by conduction and the valve (3) is opened or closed at the right temperature and time.
  • the spacer (6) is manufactured from sheet metal.
  • the spacer is L-shaped and has a first arm (7) on the body (2) outer wall which contacts the ceiling and a second arm (8) which contacts the body (2) side wall.
  • the first arm (7) has one short and two long sides in contact with the ceiling on the outer wall of the body (2), and the spacer comprises a chamber between (9) the first arm (7) and the ceiling of the body (2).
  • the gap formed between the first arm (7) and the ceiling as a result of only the edges of the first arm (7) contacting the ceiling is defined as a chamber (9) filled with ambient air. The heat accumulated in said chamber (9) is transferred to the shape memory spring mechanism (4).
  • the heat in the body (2) is transferred to the shape memory spring mechanism (4) in the most effective and correct manner, and the valve (3) opens automatically when the desired temperature is reached so as to ensure the performance of the steam cooking process and when the desired temperature is reached, the valve (3) is closed and the steam cooking process is terminated.
  • the edges of the first arm (7) contacting the body (2) ceiling are bent in a "V" form, thus allowing the spacer (6) to contact the body (2) ceiling only along a single line.
  • valve (3) and the shape memory spring mechanism (4) are fixed on the spacer (6) by means of connection members.
  • the spacer (6) comprises at least one slit (10) on the first arm (7).
  • the slit (10) enables the hot air in the chamber (9) to be transferred to the shape memory spring mechanism (4).
  • the spacer (6) comprises three slits (10) extending parallel to each other along the long side of the first arm (7).
  • the heat transfer required for the shape memory spring mechanism (4) to reach the desired temperature is performed in the most efficient manner.
