Abstract

A cooking apparatus is provided. The cooking apparatus includes a main body provided with a cooking chamber, and a steam supply device generating steam to supply the steam to the cooking chamber. The steam supply device includes a water storage unit to store water, a steam generator that is supplied with water from the water storage unit to generate steam, a water supply tube to transfer water in the water storage unit to the steam generator, and a water collection tube to transfer residual water in the steam generator to the water storage unit. Accordingly, a period to put water may be increased since the residual water in the steam generator is collected.

First claim

What is claimed is:

1. A cooking apparatus comprising:
a main body provided with a cooking chamber and a rotatably mounted door; and
a steam supply device generating steam to supply the steam to the cooking chamber,
wherein the steam supply device comprises a water storage unit to store water, a steam generator that is supplied with water from the water storage unit to generate steam, a water supply tube to transfer water in the water storage unit to the steam generator, a water collection tube to transfer residual water in the steam generator to the water storage unit, and a water flow sensor disposed at the water supply tube to sense flow of water to the steam generator, and
wherein the rotatably mounted door includes a rib on an inner surface of the door configured to gather water that drops from the steam supply device onto the inner surface of the door.

2. The cooking apparatus according to claim 1 , wherein the steam supply device comprises a steam supply tube to transfer steam generated by the steam generator to the cooking chamber.

3. The cooking apparatus according to claim 1 , wherein the steam supply device comprises a water supply pump that is disposed at the water supply tube that moves water from the water storage unit to the steam generator.

4. The cooking apparatus according to claim 1 , wherein the steam supply device comprises a water collection pump that is disposed at the water collection tube that moves water from the steam generator to the water storage unit.

5. A cooking apparatus comprising:
a main body provided with a cooking chamber; and
a steam supply device generating steam to supply the steam to the cooking chamber,
wherein the steam supply device comprises a water storage unit to store water, a steam generator that is supplied with water from the water storage unit to generate steam, a water supply tube to transfer water in the water storage unit to the steam generator, and a water collection tube to transfer residual water in the steam generator to the water storage unit, and
wherein the water storage unit comprises a water storage case mounted within the main body and a water storage container that is separately installed to the water storage case; and
the main body comprises an opening through that the water storage container passes, and a water supply door that is rotatably mounted, at a lower end thereof, to a front surface of the main body to open and close the opening during rotation of the water supply door.

6. The cooking apparatus according to claim 5 , wherein the water supply door comprises a guide rib that is provided on an inner surface thereof and is formed in a U-shape oriented downward, and a guide portion protruding inside the water supply door from an inner surface lower portion thereof, a lower end of the guide rib being formed at both sides of the guide portion.

7. The cooking apparatus according to claim 6 , wherein the water storage case comprises a drop water storage portion recessed downward at a lower portion thereof to receive and gather drop water that has dropped on the water storage case.

8. The cooking apparatus according to claim 5 , wherein:
the main body comprises a non-magnetic portion that is provided in a part adjacent to the opening of the main body and a ferromagnetic portion that is provided in the part adjacent to the opening of the main body; and
the water supply door comprises at least one magnet disposed to face the non-magnetic portion.

9. The cooking apparatus according to claim 8 , wherein the at least one magnet comprises a first magnet a portion of that faces the ferromagnetic portion and the remainder of that faces the non-magnetic portion, and a second magnet the entirety of that faces all of the non-magnetic portion.

10. The cooking apparatus according to claim 8 , wherein the main body comprises a button disposed in the part adjacent to the opening of the main body, a protrusion length of the button varying depending on a number of times the button is pressed.

11. A cooking apparatus comprising:
a main body provided with a cooking chamber; and
a steam supply device generating steam to supply the steam to the cooking chamber, wherein:
the steam supply device comprises a water storage container that is attachable to, and detachable from, the main body, and a steam generator that is supplied with water from the water storage container to generate steam;
the main body comprises an opening through that the water storage container is attached and detached, a water supply door to open and close the opening, a non-magnetic portion that is provided in a part adjacent to the opening, and a ferromagnetic portion that is provided in the part adjacent to the opening; and
the water supply door comprises at least one magnet disposed to face the non-magnetic portion and a rib on an inner surface of the water supply door that gathers water that drops from the steam supply device onto the inner surface of the water supply door.

12. The cooking apparatus according to claim 11 , wherein the at least one magnet comprises a first magnet, a portion of which faces the ferromagnetic portion and the remainder of which faces the non-magnetic portion, and a second magnet the entirety of which faces all of the non-magnetic portion.

13. A cooking apparatus comprising:
a main body provided with a cooking chamber; and
a steam supply device generating steam to supply the steam to the cooking chamber, wherein:
the steam supply device comprises a water storage container that is attachable to, and detachable from, the main body, and a steam generator that is supplied with water from the water storage container to generate steam;
the main body comprises an opening through that the water storage container is attached and detached, a water supply door to open and close the opening, a non-magnetic portion that is provided in a part adjacent to the opening, and a ferromagnetic that is provided in the part adjacent to the opening; and
the water supply door comprises at least one magnet disposed to face the non-magnetic portion,
wherein the main body comprises a button disposed in the part adjacent to the opening of the main body, a protrusion length of the button varying depending on a number of times the button is pressed.

14. A cooking apparatus comprising:
a main body provided with a cooking chamber;
a water storage unit to store water; and
a steam generator that is supplied with water from the water storage unit to generate steam, wherein:
the water storage unit comprises a water storage case mounted within the main body and a water storage container that is separately installed to the water storage case;
the main body comprises an opening through which the water storage container is attached and detached, a water supply door that is rotatably mounted, at a lower end thereof, to the main body to open and close the opening; and
the water supply door comprises a guide rib that is provided on an inner surface thereof and is formed in a U-shape oriented downward.

15. The cooking apparatus according to claim 14 , wherein the water supply door comprises a guide portion extending rearward from an inner surface lower portion of the water supply door, a lower end of the guide rib being provided at both sides of the guide portion.
