Description

Steam Generator {STEAM GENERATOR}

The present invention relates to a steam generator, and more particularly to a steam generator for generating steam supplied to the food during cooking.

Various kinds of apparatuses have been proposed to date as heating apparatuses for heating foods. The most basic heating device is a container that is in direct contact with the heat source, the contents to be cooked in such a container can be cooked by applying heat to heat.

In addition, many types of cooking apparatuses that use electric energy directly or indirectly have been developed. As an example, a microwave oven using microwaves as a heating source can be cited. A microwave oven is a cooking apparatus that generates microwaves using electricity to infiltrate a cooking object and heats the cooking object by causing molecular motion therein.

A common microwave oven is a kitchen appliance that heats the inside and the outside of the microwave by irradiating the microwave with high frequency of the magnetron, and greatly reduces the cooking time of the food due to high thermal efficiency, and loses nutritional value during cooking, thawing and warming of the food. It is also widely used because of the advantages such as cooking directly while the food is stored in the container.

Recently, microwave ovens with steam generators have been developed. The microwave oven having a steam generator supplies hot steam into the cooking chamber during cooking to prevent water from evaporating while the food is being cooked, thereby preventing food from being dried while the food is being cooked.

The above technical configuration is a background art for helping understanding of the present invention, and does not mean a conventional technology well known in the art.

As described above, the steam generator provided in the microwave oven to supply high temperature steam to the inside of the cooking chamber has a problem in that the steam generating performance is unstable so that steam cannot be stably supplied.

Therefore, there is a need for improvement.

The present invention was devised to improve the above problems, and an object thereof is to provide a steam generator having an improved structure to stably supply steam during a cooking process.

Steam generating apparatus according to the present invention comprises: a boiler unit for generating steam; A discharge part formed at one side of the boiler part to discharge steam; And a net unit installed in the boiler unit to surround the discharge unit and having a fine hole through which the steam passes.

The boiler unit may further include: a first cover part including a plurality of first convex parts and a first concave part disposed between the first convex parts; And a second cover part coupled to the first cover part to form a path through which the steam moves, and including a plurality of second convex parts and a second concave part disposed between the second convex parts. .

The first convex portion may be disposed to face the second convex portion, and the first concave portion may be disposed to face the second concave portion.

In addition, the fine holes are preferably formed to have a diameter of 0.5 ~ 1mm.

In addition, the mesh portion is preferably brazed inside the boiler.

In addition, the present invention preferably further comprises a heater for heating the boiler to generate steam.

According to the steam generating device of the present invention, by having a mesh portion formed with a fine hole in the boiler portion, so that the pressure of the front end of the discharge portion is kept constant and uniform to induce the steam discharged through the discharge portion uniformly In addition, it is possible to prevent the flakes of impurities that can be generated in the boiler portion when discharged for a long time with steam.

In addition, the present invention is to increase the residence time of the water by forming a blocking structure in the boiler portion, thereby improving the steam generation efficiency, it is possible to suppress the discharge of water in the liquid state to generate high-quality steam.

It is preferably formed to have a size.

 The mesh unit 150 provided as described above maintains a constant and uniform pressure at the front end of the discharge unit 135 to induce the steam discharged through the discharge unit 135 to be uniformly sprayed, and the boiler unit when used for a long time. (120) serves to prevent the flakes of impurities that may be generated in the discharge with the steam.

Hereinafter, the operation and effects of the steam generator 100 according to the present embodiment will be described with reference to FIGS. 1 to 4.

When an operation for supplying steam to the cooking chamber 13 of the microwave oven 10 is started, the water contained in the water tank 160 is connected to the water tank 160 and the boiler 120 to connect the connector 161. By the operation of the pump 165 installed in the through the connection pipe 161 and the inlet 130 is supplied to the inside of the boiler unit 120, with the heater unit 140 is operated with the boiler unit 120 Heat it.

The water supplied to the boiler unit 120 is increased in temperature while moving inside the boiler unit 120, whereby steam is generated in the boiler unit 120. The steam generated as described above continues to rise through the gap formed between the first recess 123 and the second recess 127, and water that is not converted into steam and remains as a liquid is still part of the flow. The first recessed part 123 and the second recessed part 127 are blocked.

As a result, the water moving inside the boiler 120 is not only heated for a longer time in the portion in which the first recess 123 and the second recess 127 are formed, and the flow toward the outlet 135 is increased. It is blocked by the blocking structure formed by the first recessed part 123 and the second recessed part 127 and is not converted into steam, and it is difficult to be discharged to the discharge part 135 in a liquid state.

The steam generating apparatus 100 of the present embodiment having the boiler unit 120 having the above-described structure not only improves steam generation efficiency by increasing the residence time of water, but also discharges water in a liquid state. By suppressing this, high quality steam can be generated.

On the other hand, the steam generated inside the boiler unit 120 passes through the mesh unit 150 before being discharged to the discharge unit 135. That is, the steam generated inside the boiler unit 120 passes through the fine holes 151 formed in the inside of the net unit 150, and then is discharged to the outside of the boiler unit 120 through the discharge unit 135. According to the present exemplary embodiment, the discharge part 135 communicates with the steam jet part 170 provided in the cooking chamber 13 through the chassis part 12, and the boiler part 120 through the discharge part 135. Steam discharged from) is evenly delivered to the food contained in the cooking chamber 13 through the steam ejecting unit 170.

The steam generating apparatus 100 of the present embodiment as described above has a mesh portion 150 in which the fine holes 151 are formed inside the boiler portion 120, so that the pressure at the front end of the discharge portion 135 is kept constant. The steam discharged through the discharge unit 135 may be induced to be uniformly sprayed, and the flakes of impurities that may be generated in the boiler unit 120 may be prevented from being discharged together with the steam when used for a long time.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
