Abstract
A steam generator and a cooking apparatus including a steam generator are provided. The steam generator may include a heater, an inflow tube, a steam generation tube, and a discharge tube and an adaptor unit connected to the steam generator may be provided. The inflow tube and the discharge tube and the discharge tube may be connected at a predetermined angle to the adaptor unit. Thus, the steam generation tube connecting the inflow tube to the discharge tube may also be inclined.
Claims13
A steam generator, comprising:
- at least one u-shaped heater configured to provide heat;
- an inclined u-shaped heating tube configured to generate steam by receiving the heat from the at least one u-shaped heater, wherein the at least on u-shaped heater corresponds in shape to the inclined u-shaped heating tube and extends along an outer surface along a length thereof;
- a water supply and drain tube configured to receive water into the steam generator and supply the water to the u-shaped heating tube;
- a first connection tube that connects the water supply and drain tube and an inflow tube of the u-shaped heating tube;
- a branch tube branched so that steam and water discharged from the u-shaped heating tube are divided and the branch tube extends in parallel with the water supply and drain tube;
- a collection tube connected to the branch tube and the water supply and drain tube to collect the water discharged from the u-shaped heating tube into the water supply and drain tube;
- a second connection tube that connects the branch tube and a discharge tube of the u-shaped heating tube;
- and
- a steam discharge tube connected to the branch tube to provide a passage through which the steam flows out of the steam generator, wherein the u-shaped heating tube extends from the first connection tube to the second connection tube in the u-shape, wherein the first connection tube is inclined at a first angle from an end of the water supply and drain tube based on a direction in which the water supply and drain tube extends such that residual water is removed from the u-shaped heating tube, wherein the second connection tube extends inclined at a second angle from a first end of the branch tube based on a direction in which the branch tube extends such that residual water is removed from the u-shaped heating tube, and wherein the steam discharge tube extends inclined at a third angle from a second end of the branch tube based on the direction in which the branch tube extends such that a condensed water is introduced into the collection tube.

A cooking apparatus, comprising:
- a cavity having a cooking chamber;
- a steam generator configured to provide steam to the cooking chamber;
- a water supply tank configured to store water supplied to the steam generator;
- and
- a drain tank in which residual water of the steam generator is stored, wherein the steam generator comprises:
- a steam generation unit provided with at least one u-shaped heater configured to provide heat and an inclined u-shaped heating tube configured to receive the heat from the at least one u-shaped heater so as to generate steam, wherein the at least one u-shaped heater corresponds in shape to the inclined u-shaped heating tube and extends along an outer surface along a length thereof;
- an adaptor unit provided with a water supply and drain tube configured to supply water to the u-shaped heating tube;
- a first connection tube that connects the water supply and drain tube and an inflow tube of the u-shaped heating tube;
- a branch tube branched so that steam and water discharged from the u-shaped heating tube are divided and the branch tube extends in parallel with the water supply and drain tube;
- a collection tube connected to the branch tube and the water supply and drain tube to collect the water into the water supply and drain tube;
- a second connection tube that connects the branch tube and a discharge tube of the u-shaped heating tube;
- and
- a steam discharge tube configured to provide a passage through which the steam flows out of the steam generator, wherein the u-shaped heating tube extends from the first connection tube to the second connection tube in the u-shape, wherein the first connection tube is inclined at a first angle from an end of the water supply and drain tube based on a direction in which the water supply and drain tube extends such that residual water is removed from the u-shaped heating tube, wherein the second connection tube extends inclined at a second angle from a first end of the branch tube based on a direction in which the branch tube extends such that residual water is removed from the heating tube, and wherein the steam discharge tube extends inclined at a third angle from a second end of the branch tube based on the direction in which the branch tube extends such that a condensed water is introduced into the collection tube.
