Abstract
An oven that effectively cools a door by adjusting a position of a cooling guide includes a casing having at least one inhalation hole and at least one ejection hole; a cooking chamber which has an opening and is placed inside the casing; a door that is rotatably coupled to one portion of the casing so as to open/close the opening; a cooling fan that discharges air introduced into the inhalation hole to the ejection hole placed at a front portion of the casing; and an air guide that is installed adjacent to the ejection hole so as to change a direction of air driven by the cooling fan. The cooling guide is installed not to disturb the flow of air that passes through the door so that the door using minimum sheets of glass can be provided.
Claims22
An oven comprising:
- a casing having at least one inhalation hole through which air outside is introduced to and an ejection hole through which air inside of the oven is discharged to outside;
- a cooking chamber placed inside the casing and having an opening;
- a door that is installed to open/close the opening and forms a flow path of air inside the door using a plurality of sheets of glass including inner glass to seal the cooking chamber;
- a cooling fan that is installed at an outer portion of the cooking chamber so as to cool the door by inhaling external air through the inhalation hole;
- a cooling flow path that is installed so that air inhaled by the cooling fan is capable of flowing toward the door in a first direction, so as to generate a flow of air inside the door;
- door flow paths that are installed so that air inhaled at an end portion of the door is capable of passing through the door and flowing toward the other end portion adjacent to the cooling flow path;
- and
- a cooling guide that is installed at the cooling flow path adjacent to the door flow paths and comprises a first end portion that extends in the first direction so as to narrow a width of the cooling flow path;
- an air guide that is installed adjacent to the ejection hole so as to change a direction of air driven by the cooling fan so that high-temperature vapor from the cooking chamber is capable of being diffused downwards;
- and
- a movement unit that contacts the air guide and moves upwards and downwards based on the received signal and adjust the air guide,
- wherein the first end portion is disposed posterior to an inner side surface that forms the door flow paths of the inner glass in the first direction so as to prevent a flow of air that passes through the door flow paths and is directed toward the outside from being disturbed.

An oven comprising:
- a casing that forms an exterior of the oven;
- a cooking chamber provided inside the casing;
- a door that is installed to open/close the cooking chamber and comprises a plurality of sheets of glass spaced apart from each other by a predetermined gap so as to form a flow path of air;
- a cooling fan that is installed at an outer portion of the cooking chamber, inhales external air, and ejects the inhaled air to the outside;
- a cooling guide that is installed within a flow path of air that is driven by the cooling fan and reduces pressure of the air by narrowing a width of the flow path;
- a control unit that performs a cleaning mode in which temperature inside the cooking chamber increases and foreign substances are pyrolized and removed and controls the cooling fan to increase speed of the elected air when the door is open;
- and
- at least one door flow path formed inside the door using the plurality of sheets of glass,
- wherein the cooling guide is installed not to protrude toward an inside of the at least one door flow path.

An oven comprising:
- a casing having at least one inhalation hole and at least one ejection hole;
- a cooking chamber which has an opening and is placed inside the casing;
- a door that is rotatably coupled to one portion of the casing so as to open/close the opening;
- a cooling fan that discharges air introduced into the inhalation hole to the ejection hole placed at a front portion of the casing;
- an air guide that is installed adjacent to the ejection hole so as to change a direction of air driven by the cooling fan;
- and
- a sensor installed to detect opening and closing of the door,
- wherein the air guide is adjusted based on a signal received from the sensor.

An oven comprising:
- a casing having at least one inhalation hole and at least one exit hole;
- a cooking chamber which has an opening and is placed inside the casing;
- a door coupled to the casing to open/close the opening door, the door including at least one door flow path that is formed an inner portion of the door so that air inhaled at one end portion of the door flows toward the other end portion;
- a cooling fan that discharges air introduced into the inhalation hole to the exit hole through a cooling flow path that is formed in an inner upper portion of the oven;
- and
- a cooling guide that is provided at the cooling flow path adjacent to the door flow paths and narrow a width of the cooling flow path to increase speed of the air flow therethrough;
- an air guide that is installed adjacent to the exit hole so as to change a direction of air driven by the cooling fan so that high-temperature vapor from the cooking chamber is capable of being diffused downwards;
- and
- a movement unit that contacts the air guide and moves upwards and downwards based on the received signal and adjust the air guide.
