Abstract

The utility model discloses an electric cooker capable of being used for cooking congee and rice. A steam collection pipe is arranged on a cooker cover. A mechanical movable disconnection type double-metal-sheet temperature sensitive switch is mounted in the steam collection pipe. The temperature sensitive switch is in series connection with a current return circuit of an electrical heating element of the electric cooker. A sealing cover is arranged at a steam inlet of the steam collection pipe and connected with a rotating piece. The sealing cover can be driven by the rotating piece to move to a position where the sealing cover is aligned to the steam inlet, and a position where the sealing cover deviates from the steam inlet. A spring is connected between the rotating piece and the sealing cover. When the sealing cover is aligned to the steam inlet, the sealing cover completely covers the steam inlet under the action of the spring. A rotating shaft of the rotating piece is connected with a handle. According to the electric cooker capable of being used for cooking the congee and the rice, switching between a rice cooking function and a congee cooking function can be realized without the need of arranging a function switch provided with an electrode contact in a circuit, and therefore the production cost and the failure rate of the electric cooker are reduced, and the competitiveness of the electric cooker is enhanced. Moreover, due to the fact that the sealing cover which covers the steam inlet is pushed and pressed by the spring, the sealing cover can cover the steam inlet more reliably.

The specific embodiment

Embodiment one

Pot lid partial structurtes that Fig. 1 draws electric cooker.Pot covers 1 and is provided with vapor collection pipe 2.Mechanical type moving fault bimetal leaf temperature sensitive switch 3 is installed in the vapor collection pipe 2, and this temperature sensitive switch is connected in the current loop of heating 4 of electric cooker as shown in Figure 3.As preferred forms, the temperature-sensitive face of the temperature sensitive switch 3 of present embodiment makes vapor collection pipe 2 form a blind hole 2 shutoff of vapor collection pipe, can prevent that so steam from touching the electrode pin of temperature sensitive switch 3, improves security.

Steam inlet 5 at vapor collection pipe 2 is provided with seal cover 6.Seal cover 6 is connected with a tumbler 7.Tumbler 7 is connected with rotating shaft 8, drives tumbler 7 by rotating shaft 8 and rotates.Under the drive of tumbler 7, seal cover 6 be movable to over against with the position of departing from steam inlet 5.Be connected with spring 9 between tumbler 7 and the seal cover 6.Under the state of steam inlet 5, that is under state shown in Figure 1, seal cover 6 seals steam inlet 5 under spring 9 effects fully at seal cover 6.

Present embodiment all is located at vapor collection pipe 2, seal cover 6, tumbler 7, spring 9 and rotating shaft 8 in the hollow pipe 10, hollow pipe 10 up/down perforations and be through to pot tops.The top of rotating shaft 8 is connected with the handle 11 of block shape, and the handle 11 of block shape covers on the top of hollow pipe 10.Turn handle 11 and can drive rotating shaft 8 rotations.Fig. 2 shows the profile of overlooking of block shape handle 11.For ease of turning handle 11, be provided with the lug 12 of radial protrusion at the sidewall of block shape handle 11.Lug 12 and handle 11 global formations.

The sidewall of hollow pipe 10 is provided with steam outlet 13, and the sidewall of block shape handle 11 is provided with steam outlet 14, and both steam outlets 13,14 are corresponding mutually, enters into steam in the hollow pipe 10 in order to discharging.Steam outlet 13,14 on hollow pipe 10 and the block shape handle 11 can arrange a plurality of.

Fig. 3 shows a kind of circuit diagram of the present utility model that can be used for.When needs are cooked, make seal cover 6 among Fig. 1 block the steam inlet 5 of vapor collection pipe 2, the steam that the interior boiling of bimetal leaf temperature sensitive switch 3 and pot is produced is isolated, bimetal leaf temperature sensitive switch 3 do not stewed in boiling temperature influence and be in normal open state, at this moment, the circuit of Fig. 3 be exactly one with magnetic steel temperature limiter 15 as the routine of the temperature controller circuit of cooking; When needs are cooked congee, make the seal cover 6 among Fig. 1 depart from steam inlet 5, make the steam that boiling produces in pot enter vapor collection pipe 2, so, logical when disconnected when bimetal leaf temperature sensitive switch 3 just can be along with the variation of vapor (steam) temperature in pot, make the heating 4 batch (-type)s energising among Fig. 3, realize the gruel boiling function of batch (-type) boiling.

The cross-sectional area of the steam inlet 5 of vapor collection pipe 2 is preferably 10 square millimeters ~ 177 square millimeters.Can make that like this steam flow that enters in the vapor collection pipe 2 is just suitable when cooking congee, can avoid because of quantity of steam excessive, cause 3 turn-off times of bimetal leaf temperature sensitive switch long and cause boiling not enough, can avoid again because of quantity of steam too small, cause 3 turn-on times of bimetal leaf temperature sensitive switch long and cause boiling excessively, cause food to overflow.

Embodiment two

Referring to Fig. 4, present embodiment has additional steam mozzle 16 on the basis of embodiment one, and the steam inlet 17 of steam mozzle 16 is communicated to outside the hollow pipe 10, and the steam (vapor) outlet 18 of steam mozzle 16 is over against the steam inlet 5 of vapor collection pipe 2.Steam mozzle 16 can make bimetal leaf temperature sensitive switch 3 sense vapor (steam) temperature more delicately, makes control more accurate.
