Then, the steam passes through the steam duct portion 25 of the handle 21 from the duct member 31 through the joint member 32 and is supplied between the inner container 34 and the bottom body 19 in the pot body 12. After that, after hitting the bimetal switch 38 located in front of the steam duct portion 25, it is drained to the outside through a drain hole (not shown) formed in the bottom body 19. When the temperature of the bimetal switch 38 is increased by the jet of steam, the energization to the aluminum brazing heater 36 is interrupted by pushing up the link member 37 as described above.

  The hot water boiled in this manner has a spout 49 located on the opposite side in the radial direction by gripping the handle 21 in a state where the operation member 60 is operated and the water supply passage inlet 46 is opened by the valve member 51. By inclining so as to incline downward, it is possible to pour out from the spout 49 through the water supply passage 50.

  At this time, due to the inclination of the pot 11, the pair of movable blocking members 77, 77 move to close the communication portion 79 and the first air vent 80. Then, the movable closing members 77 and 77 act so as to be adsorbed to the communication part 79 and the first air vent part 80 due to a pressure difference from the atmospheric pressure in the inner container 34. However, in the present embodiment, since the second air vent 81 is provided so that the movable closing member 77 is not blocked in this pouring state, the internal and external pressures are balanced through the second air vent 81 to perform adsorption. Can be canceled. Specifically, first, the movable blocking member 77 is separated from the first air vent 80 having a small opening area, and then the movable blocking member 77 is separated from the communication portion 79. As a result, it is possible to sufficiently take in air outside the machine into the inner container 34, so that it is possible to prevent the dispensing operation from being hindered.

  On the other hand, when the pot 11 falls while only the pot 11 is placed on a table or the like, the water supply passage inlet 46 and the exhaust passage inlet 65 may be immersed depending on the amount of remaining water in the inner container 34. However, in the present embodiment, since the spout 49 is provided so as to protrude forward, as shown in FIG. 7A, the spout 49 does not fall down so as to be located directly below. In addition, such a fall situation can be reliably prevented by providing the handle 21 on the opposite side, together with its weight. Conversely, as shown in FIG. 7 (B), the handle 21 is in a state of being overturned so that it touches the table, as shown in FIG. 7B.

  As a result, in order to achieve the intermediate position in FIGS. 6B and 6C or the intermediate position in FIGS. 6B and 6D, the communication portion 79 of the connection member 78 and the first air vent 80. The second air vent 81 is in a state of being reliably closed by the movable closing member 77. Therefore, it is possible to reliably prevent the water in the inner container 34 from flowing out of the machine through the exhaust passage 90. In this state, even if the water in the inner container 34 is full, the water supply passage inlet 46 as well as the spout 49 is positioned above the liquid level. Therefore, even if the water supply passage inlet 46 is opened by the valve member 51 by the operating member 60, water does not flow out of the machine through the water supply passage 50 in this state.

  As described above, in the electric pot of the present invention, the connecting member 78 having the communication portion 79 in the exhaust passage and the movable closing member 77 that closes the communication portion 79 by the inclination are disposed, and therefore the electric pot falls down. However, the liquid in the inner container 34 can be prevented from flowing out from the exhaust passage 90. In addition, the communication part 79 is provided with a second air vent 81 so as not to be blocked by the movable closing member 77 in the pouring state in which the spout 49 is inclined downward, and therefore in the inner container 34 in the pouring state. Inflow of external air is possible. Therefore, it is possible to reliably prevent the dispensing operation from being hindered during normal use.

  FIG. 8 shows a connecting member 78 applied to the electric pot of the second embodiment. As in the first embodiment, the connecting member 78 is a disc provided with a communication portion 79, a first air vent 80, a baffle plate disposing recess 82, a vent groove 83, a steam passage connecting portion 84, and a bracket portion 85. It is of shape. In the second embodiment, the second air vent 81 is provided with a rib 95 projecting downward from the lower end edge of the communicating portion 79 on the movable closing member 77 side, and the rib 95 is provided from the lower end surface. It is different from the first embodiment only in that it is constituted by a notch. In addition, the 2nd air vent part 81 which consists of this notch part is provided so that it may be located in the handle | steering-wheel 21 side which is a back side in the assembly | attachment state. The electric pot according to the second embodiment to which the connecting member 78 is applied can obtain substantially the same operation and effect as the first embodiment.

  In addition, the heating container of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the first embodiment, the second air vent 81 is configured by a slit communicating with the communication unit 79, but may be configured by an independent hole spaced from the communication unit 79. Even if it does in this way, the effect | action and effect similar to 1st Embodiment can be acquired.

  Further, the water supply passage 50 and the spout 49 are not limited to the configuration provided in the lid 39, and may be provided in the pot body 12. Even in this case, the same operation and effect as in the above embodiment can be obtained. .
