Abstract

A steam cooker having a main body, a cavity provided inside the main body, a steam generator provided to generate steam, a supply pipe connecting the steam generator to the cavity to supply steam into the cavity, a discharge pipe arranged to discharge the steam inside the cavity to the outside of the cavity, a discharge nozzle coupled to an end of the discharge pipe, and a cooling fan provided between the cavity and the main body to cool the cavity, and wherein the discharge nozzle is disposed adjacent to the bottom of the cooling fan such that steam discharged through the discharge nozzle is guided downward between the cavity and the main body by the cooling fan. The steam cooker can prevent the condensation water from falling down on the lower part of the main body.

First claim

What is claimed is:

1. A steam cooker comprising:
a main body having an opened front plate, side plates and a rear plate;
a cavity formed inside the main body and formed by side walls and a rear wall;
a steam generator to generate steam;
a supply pipe to connect the steam generator to the cavity to supply the generated steam into the cavity;
a discharge pipe to connect to the cavity to discharge steam inside the cavity therethrough;
a discharge nozzle disposed at an end portion of the discharge pipe so that the steam discharged through the discharge nozzle is diffused;
a cooling fan provided between the cavity and the main body; and
a diffusion space formed between the rear plate and the rear wall so that the steam discharged from the discharge nozzle is diffused and spread to the diffusion space by the discharge nozzle,
wherein the discharge nozzle is disposed adjacent to a bottom portion of the cooling fan such that diffused steam discharged from the discharge nozzle is guided downward between the cavity and the main body by the cooling fan.

2. The steam cooker according to claim 1 ,
wherein the discharge nozzle is disposed between the rear plate and the rear wall.

3. The steam cooker according to claim 2 ,
wherein the diffusion space is formed in a vertical direction between the rear plate and the rear wall.

4. The steam cooker according to claim 3 , wherein the discharge nozzle is disposed at an upper portion of the diffusion space, and the steam discharged from the discharge nozzle flows downward from the upper portion of the diffusion space.

5. The steam cooker according to claim 3 , further comprising:
a mounting space formed between the rear plate and the rear wall to receive the steam generator.

6. The steam cooker according to claim 5 , further comprising:
a barrier to partition space between the rear plate and the rear wall into the diffusion space and the mounting space.

7. The steam cooker according to claim 6 , wherein the barrier extends in the vertical direction between the rear plate and the rear wall, and the diffusion space and the mounting space are formed on sides of the barrier, respectively.

8. The steam cooker according to claim 3 , further comprising:
a rear support plate disposed between the rear plate and the rear wall to support the steam generator, and
wherein the diffusion space is formed between the rear plate and the rear support plate.

9. The steam cooker according to claim 1 , wherein the discharge nozzle includes a collecting space formed to collect condensation water generated when steam in the cavity is discharged to the outside of the cavity.

10. The steam cooker according to claim 9 , wherein the discharge nozzle includes a first tube portion coupled to the discharge pipe, a second tube portion having a diameter larger than a diameter of the first tube portion, an expansion portion that is provided between the first tube portion and the second tube portion and a diameter of the expansion portion increases toward the second tube portion, an inlet wall protruding radially inwardly from the first tube portion or the expansion portion and forming an inlet, and an outlet wall protruding radially inwardly from the second tube portion and forming an outlet, and
the collecting space is formed between the inlet wall and the outlet wall.

11. The steam cooker according to claim 10 , wherein a diameter of the outlet is equal to or greater than a diameter of the inlet.

12. The steam cooker according to claim 10 , wherein a diameter of the inlet is smaller than or equal to a diameter of an inner circumferential surface of the discharge pipe.
