First to the 3rd discharge orifice 25 to 27 that is used to discharge the steam in the pressure space is arranged on the central area of container cover 21, along the thickness direction of plate face from the top around first to the 3rd recessed recess 22 to 24 of bottom is arranged on first to the 3rd discharge orifice 25 to 27.Emergent according to the preferred embodiment of the invention steam exhaust device be arranged on first to the 3rd discharge orifice 25 to 27 and outside in the space between the pot cover 13.
Emergent steam exhaust device comprises: main body 31, and it has the first exhaust passage 35a that communicates with first discharge orifice 25, and is connected between container cover 21 and the outer pot cover 13; And exhaust passage opening/closing spare 51, the one side connects main body 31 and opposite side passes outer pot cover 13 and expose, and the opening/closing first exhaust passage 35a.
Exhaust passage opening/closing spare 51 is made of main part 52 and head 57, and the diameter of main part 52 dwindles along its length gradually, and head 57 is in a side of main part 52 and have the diameter of increase.Main part 52 has first to the 3rd diameter portion 53a to 53c that diameter reduces gradually, forms the external thread part 54 that connects with main body 31 on the outer diameter surface of the first diameter portion 53a.Be used for the seal 56a of sealed body 31 and the lower area that 56b is connected to the first diameter portion 53a and the second diameter portion 53b.
Exhaust passage opening/closing spare 51 join operation holes 28, handle hole 28 connects outer pot cover 13, makes the ends exposed of head 57.Form the operating groove 58 of indent at the end of head 57, this operating groove 58 makes exhaust passage opening/closing spare 51 separate with main body 31 by coin or bottle opener.Protective cap 29 is connected in outer pot cover 13 in separable mode, is used to prevent that foreign matter from entering outer pot cover 13 inboards by handle hole 28.
Form a plurality of screwed holes 43 on main body 31, screwed hole 43 links to each other with container cover 21 by screw 44, and a plurality of screw bosses 30 project upwards from container cover 21, with corresponding screw hole 43.First to the 3rd protuberance 32a to 32c is outstanding downwards from the lower surface of main body 31, to insert first to the 3rd recess 22 to 24.Make between main body 31 and the container cover 21 the seal 33a to 33c that keeps airtight conditions be connected in respectively protuberance 32a to 32c around.
Form first to three-exhauster passage 35a to 35c in main body 31, they are connected in first to the 3rd discharge orifice 25 to 27, so that by first to the 3rd discharge orifice 25 to 27 steam is effluxed.Steam pressure control device 45 and automatic steam exhaust device 49 are set on the top of main body 31, steam pressure control device 45 comes the suitably steam of discharge pressure interior volume by the opening/closing second exhaust passage 35b, thereby the constant voltage in the space that in the steamed rice process, keep-ups pressure, automatically steam exhaust device 49 blocks three-exhauster passage 35c in the steamed rice process, and well effluxes steam by opening three-exhauster passage 35c after meal in steaming.
Steam pressure control device 45 comprises: housing 46, its inner accommodation space that forms; Valve 47 is arranged on the housing 46 with move mode, is used for opening/closing second discharge orifice 26, and spring part 48, is arranged in the housing 46, is used for elastic type valve 47 being exerted pressure, thereby makes it stop up exhaust passage being lower than under the situation of predetermined pressure.
On the other hand, opening/closing spare connection part 37 projects upwards along the thickness direction of main body 31 upper surface central areas.Here, the exhaust passage opening/closing spare 51 that is used for the opening/closing first exhaust passage 35a is connected to opening/closing spare connection part 37 in separable mode.The diameter of the first exhaust passage 35a dwindles gradually along last/following direction, thus first to the 3rd diameter portion 53a to 53c of the corresponding exhaust passage opening/closing spare 51 of difference.Inside upper part at opening/closing spare connection part 37 is provided with internal thread part 38, to connect with the external thread part 54 of exhaust passage opening/closing spare 51.Be provided with in a side of congested areas by the second diameter portion 53b and connect exhaust passage 35e, it makes the first exhaust passage 35a and the common exhaust passage 35d that below will describe communicates.
Side at the first exhaust passage 35a is provided with the second exhaust passage 35b, and the second exhaust passage 35b extends upward from second discharge orifice 26 along last/following direction with the predetermined length part, and then along continuous straight runs extends; In a side three-exhauster passage 35c is set in the face of the second exhaust passage 35b, three-exhauster passage 35c extends from the 3rd discharge orifice 27 along the vertical direction with the predetermined length part, and then along continuous straight runs extends, and makes the first exhaust passage 35a between the second exhaust passage 35b and three-exhauster passage 35c.
As shown in Figure 5, in a side of main body 31 common exhaust passage 35d is set, common exhaust passage 35d communicates with the second exhaust passage 35b and three-exhauster passage 35c respectively, and extend along the vertical direction and with the exterior of outer pot cover 13.Steam discharge cap 41 side within it has the accommodation space of interim ccontaining steam and has a plurality of and exhaust hole 42 exterior at end face, and steam discharge cap 41 is pot cover 13 outside the stub area of common exhaust passage 35d is connected in separable mode.
When container cover 21 is closed and during the opening of retaining pressure container 15, and when by heater (not shown) heated pressure container 15 inboard, internal pressure raises.When internal pressure raise, steam pressure control device 45 is exhaust steam by opening the second exhaust passage 35b.Therefore in the steamed rice process, the inside of pressure vessel 15 almost keeps constant voltage.When steaming well after meal, the control module (not shown) is controlled automatic steam exhaust device 49 and is opened three-exhauster passage 35c, discharges inner steam thus.
On the other hand, when normal exhaust steam after steamed rice, unload steam discharge cap 41 from outer pot cover 13, and pull down the protective cap 29 that is connected in handle hole 28, thereby expose the end of exhaust passage opening/closing spare 51.Then, coin 59 or bottle opener (not shown) are inserted in the operating groove 58 of exhaust passage opening/closing spare 51, rotation exhaust passage opening/closing spare 51 makes head 57 outwards to give prominence to from outer pot cover 13.Therefore, when exhaust passage opening/closing spare 51 along last/when following direction was shifted to top, the connection exhaust passage 35e that is stopped up by exhaust passage opening/closing spare 51 was opened.Do not have under the blocked situation at first discharge orifice 25, the first exhaust passage 35a and connection exhaust passage 35e, the steam inside of pressure space is outwards discharged.
Although rotation exhaust passage opening/closing spare 51 is to open linkage path, if steam is not discharged from, as shown in Figure 8, then exhaust passage opening/closing spare 51 separates fully with main body 31, and discharge orifice pin 60 inserts from the outside along the first exhaust passage 35a.Therefore, first discharge orifice 25 and the first exhaust passage 35a are opened, thereby the steam inside of pressure space is effluxed.
