A protective frame is provided. The inner hook 2 described above is stored in this protective frame. The coil base of the protective frame is provided with an induction coil for inductively heating the inner hook 2, and a bottom temperature sensor that penetrates the central portion of the coil base and contacts the bottom of the inner hook 2. .

  The water tank 21 is made of plastic, for example, and is detachably attached to the front side of the rice cooker body 1. A tank lid 22 is fitted in the upper opening of the water tank 21 in a detachable state, and a tank cover 23 formed in a substantially C-shape is detachably attached to the water tank 21 as viewed from above. It is attached. The tank cover 23 is provided to prevent the user from directly touching the water tank 21 at a high temperature and not to impair the design of the rice cooker. The tank lid 22 is provided with a substantially quadrilateral steam inlet 22a that is joined to the steam outlet 6a of the steam conduit 6 provided in the lid 4 via a packing 6b. The steam inlet 22a of the tank lid 22 is located on the left side when viewed from the water tank 21 side. Further, as shown in FIG. 3, the steam inlet 22 a is provided with a communication pipe 22 b that extends downward into the water tank 21.

  As shown in FIG. 3, the steam conduit 6 is formed on the left side of the lower surface 4 a of the lid body 4 when viewed from the water tank 21 side so that the steam outlet 6 a described above is joined to the steam inlet 22 a of the tank lid 22. Is housed in a lid recess 7 provided in the housing. The steam conduit 6 has a steam inlet (not shown) joined to the steam outlet 5 a of the inner lid 5.

  The lid recess 7 described above extends in the longitudinal direction of the lid 4 so as to cover a part of the steam inlet 22a of the tank lid 22 and the inner lid 5, and on the inner lid 5 side, the steam exhaust of the inner lid 5 is exhausted. It swells in the direction of the central axis of the inner lid 5 so as to cover the outlet 5a, and on the tank lid 22 side, the dimension in the width direction is narrower than that of the inner lid 5 side as shown in FIG. It is integrated with the lower surface 4a of the lid body 4 located above.

  The elastic member 11 is provided on the peripheral edge 4b located in the vicinity of the corner on the right side of the front part of the lid 4 when viewed from the water tank 21 side among the peripheral edge 4b formed integrally with the lower surface 4a of the lid 4. (See FIGS. 1 and 2). The elastic member 11 is made of, for example, a heat-resistant rubber material, and protrudes through the peripheral edge 4b as shown in FIG. The length of the protruding portion of the elastic member 11 is set to be substantially the same as the height of the packing 6b of the steam outlet 6a when the lid body 4 is closed, for example. That is, the gap between the lid 4 and the tank lid 22 is substantially uniform by the packing 6 b and the elastic member 11 when the lid 4 is closed, and the state is maintained by the elastic member 11.

  In the rice cooker configured as described above, when steam is generated from the cooked rice in the inner pot 2 during rice cooking, the steam enters the steam conduit 6 from the steam outlet 5a of the inner lid 5, and the steam conduit 6 reaches the steam inlet 22a of the tank lid 22. Then, it enters the cooling water through the communication pipe 22 b extending into the water tank 21. At this time, when the elastic member 11 is not provided, as shown in FIG. 4, the vapor outlet 6a side of the vapor conduit 6 is pushed upward by the vapor pressure in the communication pipe 22b, and the lid 4 is inclined. In this embodiment, the elastic member 11 having substantially the same height as the packing 6b when the lid 4 is closed hits the tank lid 22 to hold the gap between the lid 4 and the tank lid 22, and the lid body. 4, the elastic member 11 is installed at a position on the opposite side of the steam conduit 6, so that the steam pressure in the communication pipe 22 b pushes up the lid 4 on the steam conduit 6 side. The inclination is slight due to the elastic member 11, and a substantially horizontal state is maintained by the elastic force of the elastic member 11.

  As described above, according to the embodiment, the peripheral edge 4b formed integrally with the lower surface 4a of the lid 4 is positioned near the corner on the right side of the front of the lid 4 when viewed from the water tank 21 side. Since the elastic member 11 that hits the tank lid 22 when the lid 4 is closed is provided at the peripheral edge 4b, the steam flow in the steam conduit 6 is caused by the pressure of the steam that flows into the communication pipe 22b of the water tank 21 during rice cooking. It is possible to prevent the lid 4 from being inclined by pushing up the outlet 6a side, and to keep the lid 4 horizontal.

  In the embodiment, it has been described that the elastic member 11 is provided on the peripheral edge portion 4b of the lid body 4. For example, as shown in FIG. The elastic member 11 a to be provided may be provided so that the elastic member 11 a hits the peripheral edge 4 b of the lid 4. The length of the protruding portion of the elastic member 11a is set so that the lid 4 is horizontal when the lid 4 is closed.

  Moreover, although it described that the elastic member 11 was provided in the peripheral part 4b located in the corner vicinity of the front right side of the cover body 4 or the front right side corner of the rice cooker main body 1, it is limited to this. Instead, any position may be used as long as the lid 4 can be kept horizontal.
