[

A door 12 is provided on a front surface of the cabinet 10 to open and close the cooking chamber 22 and an operating portion 14 is provided on the front surface of the electric room 24 to detect whether the heating device and the steam generating device 30 are driven And the state of the cooking operation can be confirmed.

The steam generator 30 includes a chamber 32 provided in the electric room 24 to communicate with the cooking chamber 22 and to which water is drained, a heater 34 provided in the chamber 32 for heating water, And a drainage portion 50 provided in the chamber 32 for preventing the non-vaporized water from remaining in the chamber 32.

Accordingly, when the cooking operation requiring steam supply is started, power is applied to the heater 34 to supply water into the chamber 32 after the inside of the chamber 32 is heated, so that water introduced into the chamber 32 The steam is generated, and when the pressure inside the chamber rises, the steam is injected into the cooking chamber 22.

At this time, the water supplied into the chamber 32 is vaporized by the heater 34 to be sprayed into the cooking chamber 22, and water not vaporized is discharged to the drainage unit 50 after being put on the bottom surface of the chamber 32, As shown in FIG.

The chamber 32 includes a main body 36 in which water is drained in a predetermined space and a heater 34 is installed and a cover 38 installed in the electric compartment 24 by sealing the main body 36 .

The main body 36 is formed with a plurality of supply holes 36a communicating with the cooking chamber 22 and an inlet hole 38a through which water is supplied to the cover 38. [

A protection panel 36b is provided on the inner wall of the main body 36 corresponding to the inflow hole portion 38a so that the water introduced into the chamber 32 through the inflow hole portion 38a flows through the supply hole portion 36a So that it is prevented from being injected into the cooking chamber 22.

A plurality of blocking panels 36c are provided on the lower side of the supply hole 36a so that the water jumping on the bottom surface of the chamber 32 is sprayed into the cooking chamber 22 through the supply hole 36a prevent.

Since the blocking panel 36c is formed in a T shape in cross section and a plurality of the blocking panels 36c are disposed apart from each other, the straight path between the bottom surface of the chamber 32 and the supply hole 36a is blocked, And the curved path between the bottom surface of the chamber 32 and the supply hole portion 36a is not blocked so that the vaporized steam can flow toward the supply hole portion 36a side.

The drain portion 50 includes a drain hole portion 54 provided on the bottom surface of the chamber 32 and an inclined surface 52 provided on the bottom surface of the chamber 32.

Since the inclined surface 52 is inclined at a predetermined angle? To the drain hole portion 54, water accumulated on the bottom surface of the chamber 32 flows to the drain hole portion 54 side.

The water flows to the side of the drain hole portion 54 along the inclined surface 52 and the water is drained to the outside of the chamber 32 along the drain hole portion 54. [

It is preferable that the drain hole portion 54 extends to the lower side of the chamber 32 and is connected to the drain pipe 62 and a drain pipe (not shown) is provided at the lower end of the drain pipe 62.

Thus, the water which is not vaporized and accumulated on the bottom surface of the chamber 32 is collected in the drain pipe along the drain pipe 62 through the drain hole portion 54. When the drain pipe is full, the user drains the drain pipe from the cabinet 10 So that the drain can is cleaned.

Here, the drain canister is a conventional drain canister used in a microwave oven equipped with a steam generator, so detailed drawings or descriptions thereof are omitted, and any type of drain can be applied.

In addition, the steam generator 30 according to the embodiment of the present invention is provided with a display device 70 for informing the user of the cleaning time of the drainage trough, An output unit 76 for performing an output operation so that the user can recognize the full capacity of the drain canister when the full capacity of the drain can be sensed by the sensor 72 and the full water level sensor 72, And a control unit 74 for determining whether the output unit 76 is driven.

Here, if the sensor is capable of sensing the water level of the water drain, any sensor may be included in the known sensor. For example, there is a float sensor that flows along the water surface of the water to be drained.

The output unit 76 includes a lamp (not shown) which is provided in the operation unit 14 and is lit when the water level of the drain canister is not less than a set value, ) May be provided.

The operation of the microwave oven including the steam generator according to the present invention will now be described.

First, when the cooking operation requiring steam supply is selected, the heating device is driven, and at the same time, power is applied to the heater 34 to heat the chamber 32.

Water is supplied to the inside of the chamber 32 after the chamber 32 is heated to a predetermined temperature or higher. This causes water to be supplied along the water supply pipe connected to the inlet hole 38a, The water flowing into the chamber 32 is prevented from being directly injected into the cooking chamber 22 by the prevention panel 36b and the shielding panel 36c.

The water introduced into the chamber 32 is heated by the heater 34 and vaporized and then raised between the protection panel 36b and the blocking panel 36c to be supplied to the interior of the cooking chamber 22 through the supply hole 36a. .

At this time, since the chamber 32 maintains the state heated to a predetermined temperature or more by the heater 34, the water introduced into the chamber 32 is vaporized before reaching the bottom surface, and flows into the cooking chamber 22).

Of course, when the flow rate of the water supplied through the inlet hole portion 38a is larger than a predetermined value, the bottom surface is filled with water. The water supply pipe connected to the inlet hole portion 38a is provided with a pump (Not shown), the pump is controlled so that the flow rate of the water supplied to the chamber 32 is maintained at a predetermined value or less.

The water supply pipe, the water supply pipe, and the pump are typical water supply devices, so detailed drawings and explanations will be omitted.

Since the power supply to the heater 34 is cut off after the cooking operation is completed, the steam remaining in the chamber 32 is liquefied and condensed on the bottom surface of the chamber 32, And passes through the drain hole portion 54 and collects along the drain pipe 62 in the drainage tank.

When the operation is continued for a long period of time, the water is desorbed by a predetermined amount or more in the drainage cistern. The full water detection sensor 72 senses this and sends an electrical signal. By the electrical signal received from the full water detection sensor 72, The output unit 76 is driven.

Thereby, the user recognizes that the drain canister is full and cleans the drain canister.

Because there is no residue in the chamber 32 due to the above-described structure and operation, it is possible to prevent malfunction and breakage of the steam generator 30 caused by the corrosion of the chamber 32 due to the residual water.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .

Also, although a microwave oven equipped with a steam generator has been described as an example, the present invention is merely an example, and the steam generator of the present invention can be used in products other than a microwave oven.

Accordingly, the true scope of the present invention should be determined by the following claims.
