Abstract

Provided is a steam cooking appliance. The steam cooking appliance includes a main body having a cavity that provides a cooking space in which a food is accommodated, a backguard extending upward from an upper portion of the main body, a water tank separately mounted on the backguard, a steam supply unit disposed outside the cavity to generate steam, thereby supplying the steam into the cooking space, and a water supply tube to supply water within the water tank into the steam supply unit.

First claim

What is claimed is:

1. A steam cooking appliance comprising:
a main body having a cavity that provides a cooking space in which a food is accommodated;
a backguard extending upward from an upper portion of the main body;
a water tank mounted on the backguard;
a steam supply unit disposed outside the cavity to generate steam and to supply the steam into the cooking space;
a water supply tube to supply water stored in the water tank into the steam supply unit;
a water supply pump disposed on the water supply tube to allow the water stored in the water tank to flow into the steam supply unit through the water supply tube; and
a flow rate adjustment valve to adjust a flow rate of the water within the water supply tube,
wherein at least one of the water supply pump and the flow rate adjustment valve is disposed in the backguard.

2. The steam cooking appliance according to claim 1 , wherein the backguard comprises:
an extension part extending upward from the main body; and
a controller to control an operation of the main body,
wherein the water tank is mounted on one side of the controller.

3. The steam cooking appliance according to claim 2 , wherein a water tank mounting space for mounting the water tank is located at an upper portion of the extension part and at a side of the controller.

4. The steam cooking appliance according to claim 3 , wherein the water tank is vertically mounted in or separated from the water tank mounting space.

5. The steam cooking appliance according to claim 3 , wherein a supply part connected to the water supply tube is disposed in a bottom surface of the water tank, and
wherein an inflow part connected to the supply part is disposed in the water supply tube.

6. The steam cooking appliance according to claim 1 , wherein the water tank comprises a supply part connected to the water supply tube, and
wherein an opening and closing member to discharge the water received in the water tank is disposed in the supply part.

7. The steam cooking appliance according to claim 6 , wherein an inflow part connected to the supply part to operate the opening and closing member is disposed in the backguard.

8. The steam cooking appliance according to claim 1 , wherein the water tank comprises a window formed of a transparent material in the backguard so that the inside of the water tank is visible from the outside.

9. The steam cooking appliance according to claim 1 , wherein a first coupling part and an inflow part extending from the water supply tube to guide the water received in the water tank to the water supply tube are disposed on the backguard, and
wherein a second coupling part selectively coupled to the first coupling part and a supply part connected to the inflow part to guide the water received in the water tank to the water supply tube are disposed on the water tank.

10. The steam cooking appliance according to claim 1 , wherein the water tank comprises a handle part, and
wherein the handle part is exposed to an outside.

11. The steam cooking appliance according to claim 1 , wherein a water tank seating space is located in the backguard, and
wherein the water tank is inserted into or withdrawn from the water tank seating space.

12. The steam cooking appliance according to claim 1 , wherein the steam supply unit is fixed to a sidewall of the cavity.
