[0042] The control panel 40 may include a display 42 for displaying various pieces of cooking information, and a control knob 44 for controlling various cooking modes of the cooking apparatus 1.

[0043] The cooker body 20 includes a cooking compartment 22 in which food put in a center region thereof is cooked while being closed, and a storage compartment 24 placed under the cooking compartment 22.

[0044] The cooking compartment 22 includes a cooking space 224 approximately shaped like a rectangular box of which a front side is opened. The cooking compartment 22 refers to a space in which an ingredient to be cooked is put, and may include a shelf on which an ingredient to be cooked or a cooking container is put. The cooking compartment 22 includes a door 222 provided in the opened front side.

[0045] The door 222 is hinged at a lower side to the cooker body 20 so as to swing frontward and open the opened front side of the cooking compartment 22. The door 222 includes a sight window 226 made of glass or the like transparent material through which a process of cooking an ingredient to be cooked in the cooking compartment 22 can be seen from the outside.

[0046] The storage compartment 24 is placed under the cooking compartment 22 and supports the cooking compartment 22. The storage compartment 24 includes a drawer 242 in which cooking utensils, cooking containers, ingredients to be cooked, etc. are stored; a water tank 244; and a water tank guide 246 supporting the water tank 244 sliding to be pushed in or pulled out. The storage compartment 24 may be formed separately from or integrally with the cooking compartment 22.

[0047] The drawer 242 may be provided to slide to be pushed into or pulled out from the storage compartment 24. A user may hold a drawer grip 248 and pushes or pulls the drawer 242 into or out of the storage compartment 24.

[0048] The water tank 244 stores water to be supplied to the steam supplier 50 for generating steam. The water tank 244 is provided in a certain region of the storage compartment 24 independent of an occupancy region of the drawer 242 not to interfere with the sliding of the drawer 242 being pushed in or pulled out. The water tank 244 shown in FIGS. 1 and 2 is arranged adjacent to the right side of the drawer 242, but not limited thereto and may be placed at the left, upper or lower side of the drawer 242. Like this, the water tank 244 is provided independently of the drawer 242 of the storage compartment 24 placed under the cooking compartment 22, so that the water tank 244 can be easily separated to be replenished with water or cleaned regardless of the operations of pushing in or pulling out the drawer 242, and be prevented from interference with cooking utensils or ingredients to be cooked, which are stored in the drawer 242, without being affected by heat. In particular, a steam generator 58 continuously receives water regardless of the operations of pushing in or pulling out the drawer 242, thereby generating steam without interruption.

[0049] The water tank 244 may be installed in a certain region of the storage compartment 24 so that its head 2443 (see FIG. 6) can be directly exposed to the front, or the water tank 244 may be covered up by a door for opening and closing the certain region.

[0050] The water tank guide 246 may be stationarily installed at the right side of the drawer 242 of the storage compartment 24 and support the water tank 244 to slide to be pushed in or pulled out.

[0051] FIG. 3 is a perspective view of the steam supplier 50 according to an embodiment of the disclosure. The steam supplier 50 includes a water supplying pipe 52, a pump 54, a water sensor 56, and the steam generator 58.

[0052] Referring to FIGS. 2 and 3, the water supplying pipe 52 refers to a tube for supplying water between the water tank 244 and the steam generator 58. The water supplying pipe 52 includes a first connection pipe 522 for connecting the water tank 244 and the pump 54, and a second connection pipe 524 connecting the pump 54 and the steam generator 58. The first connection pipe 522 includes one end portion supported on the water tank guide 246, and is extended backward from the storage compartment 24, extended upward at the back side, and connected to the pump 54. The second connection pipe 524 is extended from the pump 54 upward along the back of the cooker body 20, extended frontward on a top surface, and connected to the steam generator 58 inside the cooking compartment 22 via a heat insulator 228 surrounding the cooking compartment 22.

[0053] The water supplying pipe 52 may be generally inclined toward the water tank 244 so that water remaining after steam cooking is completed can return to the water tank 244. Alternatively, the water supplying pipe 52 may additionally include a water returning path instead of the water supplying path to return the remaining water.

[0054] The pump 54 is provided between the water tank 244 and the steam generator 58, in other words, between the first connection pipe 522 and the second connection pipe 524 of the water supplying pipe 52. The pump 54 pumps up water stored in the water tank 244 and supplies the water to the steam generator 58.

[0055] The water sensor 56 is provided in the second connection pipe 524 of the water supplying pipe 52 between the pump 54 and the steam generator 58 and detects whether water is supplied normally or abnormally. For example, when it is detected by the water sensor 56 that no water flows in the water supplying pipe 52, the operations of the steam generator 58 are stopped and it is warned that malfunction occurs. Therefore, a user may replenish the water tank 244 with water after checking whether water is present in the water tank 244. When no water flows in the water supplying pipe 52 even through water is present in the water tank 244, it may be identified that the pump 54 or the water sensor 56 is faulty.

[0056] The steam generator 58 heats up water supplied through the water supplying pipe 52, thereby generating steam. The steam generator 58 may be installed inside or outside the cooking compartment 22 (see FIG. 2).

[0057] FIG. 4 is a perspective view of the steam generator 58 according to an embodiment of the disclosure.

[0058] Referring to FIG. 4, the steam generator 58 includes a spray nozzle 582 for spraying water, a heater 584 for turning the sprayed water into steam, and a fan 586 for circulating the steam in the cooking compartment 22.

[0059] The spray nozzle 582 sprays water, which is intermittently received from the water supplying pipe 52, in the form of mist. The spray nozzle 582 is positioned around the shaft of the fan 586, and the heater 584 surrounding the fan 586 turns water into steam.

[0060] The heater 584 heats up water sprayed out in the form of mist by the spray nozzle 582, thereby instantaneously turning the sprayed water into steam. The heater 584 may surround the fan 586 circularly many times.

[0061] The fan 586 disperses water, sprayed out in the form of mist, toward the heater 584, and circulates the steam into the cooking compartment 22. The fan 586 may spin based on a motor. The motor may be controlled under control of the controller. The controller may include a heater compensation algorithm to make up for temperature change and thermal loss in the cooking compartment 22 due to water supply.

[0062] FIG. 5 is a perspective view of the fan 586 in FIG. 4. The fan 586 may include a plurality of, for example, seven blades 5866 from the center to the circumference. The blades 5866 includes first vanes 5862 radially extended in a horizontal direction, and second vanes 5864 integrally bent from a radial edge of the first vane 5862 and extended upward. The first vane 5862 may include a groove 5868 radially extended from the center. With such a structure, the blades 5866 can guide mist of water, which is sprayed from the center by the spray nozzle 582, to move toward the heater 584 while spinning.

[0063] FIGS. 6 and 7 are perspective views of assembled and separated states between the water tank 244 and the support guide according to the first embodiment of the disclosure, respectively, and FIG. 8 is a cross-sectional view taken along line A-A of FIG. 6.

[0064] Referring to FIGS. 6 to 8, the water tank 244 includes a storage main body 2441 shaped like a quadrangular box opened upward, the head 2443 provided in the front of the storage main body 2441, and a connector 2445 provided in the back.

[0065] The storage main body 2441 includes at least one partition 2442 in a lengthwise direction thereof. The storage main body 2441 includes a plurality of water storage spaces 2444 formed by the partitions 2442. The partition 2442 is formed with a communicating portion 2446 through which water flows between the plurality of water storage spaces 2444.

[0066] The storage main body 2441 may be variously shaped without being limited to the quadrangular box. Further, the storage main body 2441 may have a single water storage space 2444 without the partitions 2442. The storage main body 2441 is not necessarily opened upward, but may include a space to be filled with water, and an inlet through which water is injected into this space.

[0067] The head 2443 is exposed to the front of the storage compartment 24 (see FIG. 2), and used as a grip of which a user takes hold to push in or pull out the water tank 244. The head 2443 may be formed to have a cross-section larger than the width of the storage main body 2441.

[0068] The connector 2445 includes a vertical portion 2447 extended upward from the bottom of the water storage space 2444 of the storage main body 2441, and a horizontal portion 2449 horizontally extended backward. The connector 2445 transfers water filled in the water storage space 2444 to the water supplying pipe 52. The connector 2445 may be stationarily supported on the storage main body 2441. Therefore, when the water tank 244 slides to be pushed in or pulled out, the connector 2445 also slides. In result, the end of the horizontal portion 2449 is fastened to the end of the water supplying pipe 52 supported in the water tank guide 246 when pushed in, but separated from the end of the water supplying pipe 52 when pulled out.

[0069] The water tank 244 may further include a top cover for covering the opened top. In this case, the connector 2445 may be stationarily supported at the back end of the top cover.

[0070] The water tank guide 246 includes a guide main body 2462 having a space for accommodating the water tank 244, a stationary supporter 2464 stationarily supporting the guide main body 2462 on the storage compartment 24 (see FIG. 2), and a water supplying-pipe supporter 2466 provided in the back of the guide main body 2462.

[0071] The guide main body 2462 is opened frontward so that the water tank 244 can slide to be pushed in or pulled out. The guide main body 2462 accommodates only the storage main body 2441 except the head 2443.

[0072] The stationary supporter 2464 is fastened to the ceiling of the space, in which the guide main body 2462 is installed, by, for example, a screw in the storage compartment 24. Alternatively, the stationary supporter 2464 may be fastened to the lateral sides or bottom of the space in which the guide main body 2462 is installed.

[0073] The water supplying-pipe supporter 2466 is shaped like a tub and provided on a path along which the horizontal portion 2449 of the connector 2445 moves when the water tank 244 is pushed in or pulled out. The end of the water supplying pipe 52 is inserted in and fitted to the water supplying-pipe supporter 2466. When the water tank 244 is pushed in or pulled out, the horizontal portion 2449 of the connector 2445 is fastened to or separated from the end of the water supplying pipe 52 fitted to the water supplying-pipe supporter 2466. In this case, the connector 2445 and the water supplying pipe 52 are tightly fastened and sealed to prevent water leak.

[0074] FIG. 9 is a perspective view showing an arranged state of the water tank 244 according to a second embodiment of the disclosure.

[0075] Referring to FIG. 9, the drawer 242 includes a storage space 2422, and a accommodation space 2426 in which the water tank 244 is put independently. In other words, the water tank 244 and the water tank guide 246 are installed in the storage compartment 24 without being in contact with the accommodation space 2426 of the drawer 242. The accommodation space 2426 is formed separately from the storage space 2422 by a right wall 2427 of the drawer 242 and a partition wall 2424. In the accommodation space 2426, a real wall 2428 of the drawer 242 may be removed in order to prevent interference with the water tank guide 246 while the drawer 242 is sliding to be pushed in or pulled out.

[0076] The right wall 2427 of the drawer 242 may be provided with a rail 2429 on the outer side thereof for sliding movement of the drawer 242. The water tank guide 246, which supports the water tank 244 to slide to be pushed in or pulled out, is stationarily supported on the storage compartment 24 above the accommodation space 2426.

[0077] In this way, the water tank 244 is independently provided in the drawer 242 regardless of the sliding of the drawer 242 to be pushed in or pulled out, thereby not only preventing interference with cooking utensils, cooking containers, or ingredients to be cooked stored in the storage space of the drawer 242, but also continuously supplying water to the steam generator 58 even when the drawer 242 is pushed in or pulled out.

[0078] FIG. 10 is a perspective view showing an arranged state of the water tank 244 according to a third embodiment of the disclosure.
