In this electric pot, a lid that closes the upper end opening of the inner container is rotatably attached to the pot body, and an inner lid that suppresses the rise of superheated steam is disposed on the lid.

  The inner lid described in Patent Document 2 also serves to prevent ejection of a high-temperature liquid during boiling. Therefore, it is possible to minimize the volume of the inner container and reduce the size. In addition, the inner lid is provided with a bulging portion that bulges upward in the central portion, and is configured to ensure a space for discharging steam.

  However, in the electric pot of Patent Document 2, in order to ensure the pressure resistance performance against the internal pressure that rises at the time of boiling, the full water level of the inner container has a predetermined space between the liquid level that rises at the time of boiling and the inner lid. It is necessary to set so that it can be secured. For this reason, the total height is increased by the space for securing the margin.

When the pot 11 is placed on the base 10 and the aluminum brazing heater 37 is turned on by operating the power switch member 28, the water in the inner container 34 is heated.

  In the case where the user has stored water up to the full water level, when the water in the inner container 34 is heated by heating, the water surface rises due to the expansion of the water. Then, when the liquid is substantially boiled, the liquid level rises to a position where it comes into contact with the inner lid 74 as indicated by a two-dot chain line in FIG. For this reason, when the water level is undulated by bubbles generated from the bottom of the inner container 34 due to the boiling of water, the undulating action is canceled (suppressed), and the undulating action is concentrated in the bulging portion 78. To do. And in this bulging part 78, a wave action is further suppressed by the inner peripheral surface, and it prevents that the water droplet of hot boiling water spouts out.

  On the other hand, when the user stores water in the inner container 34 up to a position exceeding the full water level, when the water level rises due to expansion, the liquid level passes through the through portion 81 as shown by a one-dot chain line in FIG. Thus, it is located above the inner lid 74. In this case, a slight undulation work occurs on the liquid surface, but the undulation work is minimized by the inner lid 74.

  Further, when the water in the inner container 34 boils, steam is generated almost simultaneously with the undulation of the liquid surface. The steam passes through the vent hole 79 at the upper end of the bulging portion 78, and then flows into the exhaust passage 95 from the exhaust passage inlet 67 positioned below the vent hole 79. Then, the steam flows into the baffle plate 97 from the movable closing member arrangement portions 65A and 65B through the substantially communicating portion 84, and the blocking surface 97a of the baffle plate 97 prevents the flow into the exhaust port member 91. Is done. As a result, the flow is divided into a part that passes through the vent hole 98 and a remaining part that does not pass through the vapor diversion port 99 and flows into the branch connection part 96.

  A part of the steam that has passed through the vent hole 98 flows into the exhaust port member 91 and is exhausted to the outside through the exhaust port 92 at the upper end. In addition, the remainder branched from the steam diversion port 99 to the branch connection portion 96 is supplied between the inner container 34 and the bottom body 19 through the steam passage 33, hits the bimetal switch 39, and then enters the bottom body 19. It drains to the outside from the drainage hole (not shown) formed. When the temperature of the bimetal switch 39 is increased by the jet of steam, the energization of the aluminum brazing heater 37 is interrupted by pushing up the link member 38 as described above.

  The hot water boiled in this way has the spout 50 located on the opposite side in the radial direction by gripping the handle 21 in a state where the operation member 62 is operated and the water supply passage inlet 47 is opened by the valve member 52. It can be poured out from the spout 50 through the water supply passage 51 by tilting so as to tilt downward.

  Thus, in the electric pot of this embodiment, since the valve member 52 is provided at the water supply passage inlet 47 of the water supply passage 51 on the front side, water droplets caused by boiling do not spout from the spout 50. Further, since the valve member 52 is provided so as to be movable in the vertical direction, between the valve member 52 and the movable closing member disposing portions 65A and 65B for accommodating the movable closing members 82 and 82 for preventing hot water leakage on the back side. It is possible to provide a space for discharging steam that can be effectively used for the above.

  And since the liquid level of the inner container 34 is set to a height at which the liquid level is substantially positioned on the inner lid 74 in a state where the water level has risen due to boiling, the inner lid 74 suppresses the rippling of the liquid during boiling. The wavy action can be concentrated on the bulging portion 78. As a result, in this embodiment, the water supply passage 51 is configured to be openable and closable by the valve member 52. However, even when the spout 50 not provided with the valve member 52 is open, water droplets caused by boiling are poured. There is no jet from the mouth 50. Moreover, since the volume of the inner container 34 can be reduced to the maximum, the overall size can be reduced.

  In the present embodiment, the exhaust passage inlet 67 is positioned below the vent hole 79 which is the upper end of the bulging portion 78, so that a distance for cooling the overheated steam can be secured, and the exhaust flow Therefore, it is possible to prevent high-temperature steam from being discharged from the exhaust port 92. Furthermore, this structure can act so that even if hot water droplets are ejected at the time of boiling, they are not ejected to the outside through the exhaust passage 95.

  In addition, in this embodiment, since the inner lid 74 is provided with the through-hole 81, even if water exceeding the full water level is stored in the inner container 34 due to misuse by the user, excessive pressure increase in the inner container 34 is prevented. Therefore, safety can be ensured.

  Furthermore, in this embodiment, since the bulging portion 78 is a resin product different from the inner lid 74, a volume (height) that can sufficiently withstand the pressure during liquid boiling or the like can be ensured. Further, since the inner lid 74 excluding the bulging portion 78 is made of metal, it can sufficiently withstand superheated steam and high-temperature liquid. Furthermore, in this embodiment, since the receiving member 58 for biasing the valve member 52 that closes the water supply passage inlet 47 is provided separately from the inner lid 74, it is arranged on the outer peripheral edge of the inner lid 74. At the time of maintenance such as replacing the provided seal member 75, other members such as the spring 59 and the valve member 52 are not separated even if the inner lid 74 is removed. Therefore, workability at the time of maintenance can be improved.

A plurality of vent holes 109 are provided on the upper end blocking surface of the bulging portion 108. Around the bulging portion 108, there is provided a screwing portion 110 for fixing the inner lid ring 106 to the lid main body 41 by screwing, and an insertion corresponding to the screwing portion 105 of the inner lid main body 100. A hole 111 is provided. In addition, a reflux hole 112 corresponding to the first circulation hole 103 of the inner lid body 100 is provided on the rear side portion of the inner lid ring 106.

  Further, the inner lid ring 106 is provided with a concave portion 113 having a generally convex shape in plan view that is recessed downward so as to be positioned below the valve member 52 disposed in the lid main body 41. In this recess 113, a positioning portion 114 is provided so as to protrude upward so as to be positioned below the operation receiving portion 55, and the spring 59 of the valve member 52 is positioned and held by this thick portion. ing. The recess 113 is provided with a plurality of water holes 115 through which water in the inner container 34 flows to the water supply passage inlet 47. In the present embodiment, as shown in FIG. 6, the recess 113 is provided with a first rib 116 that further protrudes downward from the outer peripheral edge. In addition, a pair of second ribs 117 having a substantially U shape are provided inside the first rib 116 so as to cover a lower region of the positioning portion 114. Further, a pair of third ribs 118 is provided between the first rib 116 and the opening of the bulging portion 108. These ribs 116 to 118 are provided so as to contact the upper surface of the inner lid main body 100 in the assembled state.

  The inner lid 74 is fixed by screwing an inner lid ring 106 so as to cover the lid main body 41 in a state where the valve member 52 and the spring 59 are disposed. Thereafter, the inner lid body 100 is disposed so as to cover the inner lid ring 106 and fixed by screwing.
