Abstract

Disclosed is technology about a heating container. The heating container includes: a first container having an open part, and storing a heating element and an object to be heated by the heating element; a cover opening and closing the first container, and a pressure control part controlling pressure in the first container when the heating element is emitting heat in a state in which the cover is mounted. The cover includes a pressure control hole penetrating the cover, and the pressure control part controls the degree of the opening/closing of the pressure control hole. The pressure control part can include a body provided in tight contact with at least one part of the pressure control hole. In this case, one side of the body can be provided to be fixed to the outer surface of the cover. In accordance with the present disclosure, since the internal pressure can be discharged to the outside through the pressure control hole provided on the cover, the cover can be prevented from being separated from the first container or bloated to no less than a predetermined level due to the heat emitted from the heating element and the pressure produced during the procedure of heating the object. Meanwhile, when a reaction of the heating element is stopped or reduced, the pressure control hole is blocked or closed to a proper level through the pressure control part, and, as a result, there can be an effect of maintaining the pressure in the first container at a proper level until the object becomes cooked to a level which a user wants.

Unlike the heating vessel 100 that directly controls the degree of opening and closing of the pressure control hole 122 through the pressure control unit 130 , the heating vessel 100a has a first depression 124 through the pressure control unit 130 . By controlling the degree of opening and closing of the pressure control hole 122 can be indirectly controlled the degree of opening and closing. By providing a space between the pressure regulating part 130 and the pressure regulating hole 122 through the first recessed part 124, the heating container 100a generates heat from the heating element 10 and the heating process of the object 20. The pressure control unit 130 is attached to the pressure control hole 122 by the surface tension of the water to prevent the problem that the pressure control unit 130 may not be able to control the opening and closing degree of the pressure control hole 122 in advance, It can provide the effect of maintaining the pressure inside the first container 110 at a more appropriate level until it is cooked to the level required by the user.

In addition, the heating container 100a disclosed in the present specification provides a pressure adjusting part 130 on the outer surface of the cover 120 so as to cover a part of the first recessed part 124 , so that the inside of the first container 110 . By allowing at least a portion of the steam to be discharged to the outside, it is possible to provide an effect of reducing the occurrence of dew condensation inside the first container 110 .

In addition, by providing the first recessed part 124 to be recessed in the direction of the first container 110 in the cover 120 , when the steam inside the first container 110 flows along the inner surface of the cover 120 , the first depression It is possible to provide the effect of being downwardly from the portion 124 and effectively provided to the object 20 . In order to further strengthen this, as shown as an example in FIG. 5 , an inclined surface may be provided in the first recessed portion 124 .

Figure 5 (a) shows the pressure control unit 130 of the first recessed portion 124 before the heating element 10 generates heat or when the heating element 10 is generating heat in a situation suitable for cooking the object 20 . to keep the internal pressure of the first container 110 at an appropriate level. In this case, the pressure adjusting unit 130 does not block a part of the first recessed part 124 so that the steam inside the first container 110 can be discharged through the first recessed part 124 communicating with the outside. It is possible to reduce the occurrence of dew condensation inside the first container 110 .

5 (b) shows that when the internal pressure of the first container 110 exceeds an appropriate level due to the heating element 10 being heated, the cover 120 is separated from the first container 110 or the object 20 is overheated. It shows a case in which the pressure control unit 130 is opened to prevent it from happening.

From the above, various embodiments of the present disclosure have been described for purposes of illustration, and it will be understood that various modifications are possible without departing from the scope and spirit of the present disclosure. And the various embodiments disclosed above are not intended to limit the spirit of the present disclosure, the true spirit and scope will be presented from the following claims.
