Technical field
The utility model relates to field of kitchen electric appliance, in particular to a kind of pressure limiting device, has the upper cover of this pressure limiting device and has the cooking apparatus of this upper cover.
Background technology
At present, existing Pressure rice pot mostly adopts magnetic valve to promote pressure bead and realizes boosting and step-down in pot, and specifically, the working condition of magnetic valve is as follows: when electromagnet is not energized, push rod moves near the direction of bead, and bead is pushed away steam (vapor) outlet to make to communicate with the external world in pot; During electromagnet energising, push rod moves to the direction away from bead, and now, the outlet of bead closed steam makes pot inner pressure increase; But, in the process of cooking, because rice cooker need keep high pressure for a long time, namely need to utilize bead closed steam to export, this just requires that electromagnet maintains "on" position for a long time, but electromagnet works long hours and can produce the harmful effects such as temperature rise, and this easily causes security incident, and reduces the service life of electromagnet.
Utility model content
In order to solve the problems of the technologies described above one of at least, an object of the present utility model is to provide the pressure limiting device that a kind of structure is simple, energy consumption is low, safe and reliable.
Another object of the present utility model is to provide a kind of upper cover with above-mentioned pressure limiting device.
Another object of the present utility model is to provide a kind of cooking apparatus with above-mentioned upper cover.
For achieving the above object, the embodiment of the utility model first aspect provides a kind of pressure limiting device, be arranged in upper cover and cover, for controlling the culinary art pressure of cooking apparatus, cover in described and be provided with via hole, described pressure limiting device comprises: exhaust steam valve, be arranged on described in cover, and can close or discharge described via hole; Metal pushrod, be arranged on movably described in cover, and described exhaust steam valve can be touched, make described exhaust steam valve discharge described via hole; And electromagnet, be arranged on described in cover, and be provided with the power switch, at least one first winding and at least one the second winding that are connected in series mutually with power supply, and the shearing device in parallel with described second winding; Wherein, described power switch closes, and described metal pushrod away from described exhaust steam valve, makes described exhaust steam valve close described via hole by described electromagnet attracts.
After it will be appreciated by persons skilled in the art that electromagnet energising, the attraction that metal produces is increased with the increase of the inner winding resistance of this electromagnet.
In addition, what deserves to be explained is, inside cover and be provided with protective cover, this protective cover has spatial accommodation, and this protective cover is provided with the intercommunicating pore be communicated with this spatial accommodation, a sealing member sheathing at the periphery of intercommunicating pore, to seal spatial accommodation; Exhaust steam valve is positioned at spatial accommodation, and metal pushrod is positioned at outside spatial accommodation, and metal pushrod is connected with seal near one end of exhaust steam valve, and impels seal to be out of shape to touch the exhaust steam valve in container cavity by metal pushrod.
