Description

A high-speed heating cooking device that eliminates heating blind spots {HEATING COOKER}

The present invention relates to a heating cooking apparatus, and more particularly, to a heating cooking apparatus using steam to eliminate a heating blind spot.

In the case of a conventional cooking apparatus that heats water and a heating object, the efficiency of heating water is low. Conventionally, in order to boil water, when heat energy from the outside of the cooking device containing water heats the bottom surface of the cooking device, the heated bottom surface heats the water inside the cooking device. That is, heat energy from the outside of the cooking device is transferred to the water inside the cooking device through the bottom surface of the cooking device, and heat loss occurred while the heat energy was transferred through the bottom surface.

In order to solve this problem, a steam generating chamber for generating steam is provided at a lower portion, a cooking vessel accommodating a heating object and a liquid is disposed on the upper portion of the steam generating chamber, and then steam generated in the steam generating chamber is disposed in the cooking vessel. There is known a heating cooking apparatus that heats and cooks water accommodated in the cooking vessel and a heating object by supplying it to the cooking vessel through a micro-hole formed in the bottom of the cooking vessel.

However, when steam is sprayed into the cooking vessel through micro-holes formed in the bottom surface of the cooking vessel to directly heat water and the object to be heated in the cooking vessel, a heating blind spot occurs.

That is, the edge of the bottom surface of the cooking vessel becomes a heating blind spot. Because the heating blind spot is the point where the bottom surface and the side wall of the cooking vessel meet, it is impossible to form micro-holes, so steam is not supplied directly. It is a blind spot for heating that is not supplied.

That is, as the diameter of the cooking vessel increases, the interval between the micropores formed on the bottom surface of the cooking vessel increases, so that an area to which steam is not directly supplied increases.

As such, when the number of dead zones in the cooking vessel increases, there is a problem in that steam is not uniformly supplied to the inside of the cooking vessel.

In order to solve this problem, it is possible to form a dense gap between the micropores on the bottom surface of the heating tank, but this requires a lot of micro-hole processing cost, and the micro-holes are formed on the bottom surface of the heating tank only within the specification range of the micro-hole processing machine. Since it can be processed, there is a limit that the height of the cooking vessel cannot exceed the maximum processing height of the microhole processing machine. .

In addition, in order to form micro-holes on the bottom surface of the cooking vessel, only a cooking vessel made of a material capable of processing fine holes can be used, and thus, there is a problem in that the material of the cooking vessel is also limited.

1 shows a heating cooking apparatus according to a first embodiment of the present invention.

As shown in the drawing, the heating and cooking apparatus 1a according to the first embodiment of the present invention includes a heating tank 10 , a steam generating chamber 20 , a steam supply pipe 30 , and a steam spray pipe ( 40).

The heating tank 10 has a hollow cylindrical shape with an upper opening.

A cavity 11 is formed in the heating bath 10 .

The cavity 11 is a region in which a heating object is cooked, and accommodates the heating object and water as a liquid.

The steam generating chamber 20 is an area for generating steam for heating the heating object and water accommodated in the cavity 11 of the heating tank 10 .

The steam generating chamber 20 has a sealed tubular shape, and is stacked on the heating tank 10 . The steam generating chamber 20 is separably stacked with the heating bath 10 .

A heater 23 is provided in the steam generating chamber 20 to heat the water accommodated in the steam generating chamber 20 to generate steam and at the same time generate hot water.

Hot water is stored in the lower region inside the steam generating chamber 20 , and steam is stored in the upper region. Steam generated in the steam generating chamber 20 is supplied to the cavity 11 of the heating tank 10 through the steam supply pipe 30 .

On the other hand, as steam is generated by heating water with the heater 23 in the steam generating chamber 20 , the internal pressure of the steam generating chamber 20 is higher than the pressure (atmospheric pressure) of the cavity 11 of the heating tank 10 . It becomes high, and the steam generated in the steam generating chamber 20 can be supplied to the cavity 11 of the heating tank 10 through the steam supply pipe 30 .

The internal pressure of the steam generating chamber 20 in which steam is generated is equal to or greater than atmospheric pressure, and the internal temperature is greater than or equal to 100°C. For example, if the absolute pressure inside the steam generating chamber 20 is 1.5 atmospheres, the boiling point inside the steam generating chamber 20 is about 110°C. Accordingly, a phase change occurs in which water in the steam generating chamber 20 is changed from liquid water to gaseous steam at a boiling point of 110°C. However, even at 110° C. or higher, there may be water molecules that do not phase change into steam, which is gas, and maintain the state of liquid water. The state in which the original phase is maintained even when heated above the temperature at which the phase change occurs is called superheating. Therefore, the hot water generated in the steam generating chamber 20 may include superheated water.

A plurality of fine steam injection ports 41 for finely dividing steam flowing along the steam supply pipe 30 and spraying it to the heating tank 10 are formed in each steam injection pipe 40 .

On the other hand, steam is finely divided by the plurality of steam fine injection ports 41 and injected into the heating bath 10 , thereby generating a pressure difference between the steam generating chamber 20 and the heating bath 10 .

Accordingly,. The plurality of steam fine injection ports 41 finely divide the steam generated in the steam generating chamber 20 and then introduce it into the heating tank 10, control the pressure of the steam generating chamber 21, and the steam generating chamber ( The pressure of 21 ) is maintained higher than the pressure of the cavity 11 of the heating bath 10 . In addition, the sum of the areas of the plurality of steam fine injection holes 41 is formed such that the steam pressure of the steam generating chamber 20 is maintained higher than the pressure of the cavity 11 of the heating tank 10 .

On the other hand, the plurality of steam fine injection ports 41 of each steam injection pipe 40, as shown in FIG. 2, parallel to the bottom surface of the heating bath 10 in the longitudinal direction of the steam injection pipe 40 formed at intervals along the

In addition, the plurality of steam fine injection ports 41 of each steam supply pipe 30 are formed on the outer peripheral surface located on the opposite side of the turning direction of each steam injection pipe 40 .

As such, the steam injection pipe 40 forms a plurality of fine steam injection holes 41 , so that the steam injection pipe 40 is a steam supply pipe by the reaction force of the steam injected through the plurality of steam fine injection holes 41 . The steam is sprayed into the cavity 11 of the heating bath 10 while turning around the 30 in the opposite direction to the direction in which the steam fine injection hole 41 is formed.

Here, the heating and cooking apparatus 1a according to the first embodiment of the present invention is another embodiment, and as shown in FIG. ) may be disposed symmetrically while forming an isometric angle on the outer periphery of the steam supply pipe 30 with the interposed therebetween. In this case, in each of the pair of steam injection pipes 40 disposed opposite to each other with the steam supply pipe 30 interposed therebetween, a plurality of fine steam injection ports 41 are located on the opposite side of the turning direction of the steam injection pipe 40 . is formed on the outer peripheral surface of Accordingly, by the reaction force of the steam injected through the plurality of steam fine injection ports 41 formed in each steam injection pipe 40 , each steam injection pipe 40 is finely steamed around the steam supply pipe 30 .
