Vapor Heating Type Cooking Apparatus

Abstract

The present invention relates to a vapor heating type cooking apparatus cooking food materials using high pressure vapor as a heat source. A vapor heating type cooking apparatus includes: a vapor supply section generating the high pressure vapor; a vapor supply pipe and a vapor discharge pipe for introducing and discharging the high pressure vapor; a body section including a vapor introduction opening connected to the vapor supply pipe, an interior space having a dual structure so as to circulate the high pressure vapor in the caldron in which food materials are accommodated, a vapor discharge opening provided between the interior space and the vapor discharge pipe; a cooling water supply pipe and a hot water discharge pipe; a lid section including a cooling water introduction opening connected to the cooling water supply pipe, a storage space having a dual structure, in which the cooling water is temporarily stored, and a hot water discharge opening provided between the storage space and the hot water discharge pipe; and a control section for controlling introduction and discharge of the high pressure vapor, the cooling water, and the hot water.

1 . A vapor heating type cooking apparatus cooking food materials using high pressure vapor of a predetermined temperature as a heat source, the cooking apparatus comprising: 
 a vapor supply section generating the high pressure vapor of the predetermined temperature;    a vapor supply pipe and a vapor discharge pipe for introducing and discharging the high pressure vapor of the predetermined temperature which is generated in the vapor supply section;    a body section comprising a vapor introduction opening connected to the vapor supply pipe to introduce the high pressure vapor, an interior space receiving a caldron in which the food materials are accommodated and having a dual structure for heating the entire caldron by circulating the high pressure vapor introduced from the vapor introduction opening, a vapor discharge opening provided between the interior space and the vapor discharge pipe for discharging the high pressure vapor;    a cooling water supply pipe through which cooling water of below a predetermined temperature is introduced and a hot water discharge pipe through which hot water of above a predetermined temperature is discharged;    a lid section disposed at an upper portion of the body section to close the caldron, the lid section comprising a cooling water introduction opening connected to the cooling water supply pipe to introduce the cooling water, a storage space having a dual structure, in which the cooling water introduced from the cooling water introduction opening is temporarily stored to condense the vapor, and a hot water discharge opening is provided between the storage space and the hot water discharge pipe to discharge the hot water; and    a control section for controlling introduction and discharge of the high pressure vapor, the cooling water, and the hot water.    
   
   
       2 . A cooking apparatus according to  claim 1 , wherein the control section comprises: 
 a temperature sensor detecting the temperature of the interior of the body section and the temperature of the interior of the hot water discharge section;    a display window displaying a result detected by the temperature sensor;    a logic circuit determining the introduction and the discharge of the high pressure vapor, the cooling water, and the hot water on the basis of the result detected by the temperature sensor; and    an automatic valve operated by signals transferred by the logic circuit.    
   
   
       3 . A cooking apparatus according to  claim 1 , wherein the hot water discharge pipe is connected to an external hot water storage tank to provide the hot water for heating and supply of the hot water.  
   
   
       4 . A cooking apparatus according to  claim 1 , wherein safety valves are provided so as to be communicated with the interior space of the body section and the storage space of the lid section, respectively to discharge the vapor or the cooling water when the pressures of the interior space of the body section and the storage space of the lid section are above a predetermined value.
