Abstract
The invention discloses a cover-closing in-place safety device of an electric pressure cooker, which comprises a cover component, an inner cooker component and a cooker body component, wherein the inner cooker component is arranged on the cover component; the inner pot component is arranged between the pot cover component and the pot body component; the pot cover component comprises a face cover, an inner cover and a first magnet; the pot body component comprises a reed switch connected with a main control circuit of the electric pressure cooker; the inner pot assembly includes a second magnet that is displaceable relative to the reed switch. The situation that the electric pressure cooker still does not work after the cover is completely closed in place due to the fact that the distance between the first magnet and the reed switch is far and the reed switch cannot sensitively sense the magnetism of the first magnet in the prior art is avoided. And, the pot cover assembly can be detachably mounted on the pot body assembly, thereby facilitating the cleaning of the pot cover assembly. The invention also provides the electric pressure cooker with the cover closing in-place safety device and the simple structure.
Description
Technical field
The present invention relates to electric pressure cooking saucepan field, more particularly, to a kind of closing lid in place safety device and with the closing lid in place
The electric pressure cooking saucepan of safety device.
Background technology
Traditional electric pressure cooking saucepan, whether being generally all not provided with the closing lid conducting of safety device, i.e. its control circuit in place,
Whether covered with pot cover or whether closing lid is not in contact in place, i.e., why not the closing lid state of pot cover is as influenced electric pressure cooking saucepan control electricity
The break-make on road.There is following problems for such technical solution:As soon as closing lid is not in place, user leads the circuit of electric pressure cooking saucepan
Logical, heat-generating disc work because interior pot cannot be sealed effectively, then cannot play pressure, electric pressure cooking saucepan cisco unity malfunction is not achieved in pot
Cook effect;Second is that closing lid is not in place, pot cover fastens not exclusively with outer pot, that is, has allowed to pressure, when pressure reaches certain value,
It is also possible to pot cover can be washed open and generate quick-fried pot accident, personal safety as well as the property safety may be jeopardized.
Currently, there is a kind of electric pressure cooking saucepan to use closing lid location switch, which includes being arranged in pot cover
The tongue tube for serving as a contrast the permanent magnet of the inside of lid and being arranged on jacket, tongue tube are connected with electric pressure cooking saucepan governor circuit,
Also, when electric pressure cooking saucepan closing lid in place when, tongue tube is corresponding with permanent magnet.When closing lid in place when, tongue tube senses permanent magnetism
Ferromagnetism, automatic be closed are powered, and connect electric pressure cooking saucepan and are powered on, and when closing lid is not in place, tongue tube incudes less than magnetism, then not
It is powered, electric pressure cooking saucepan does not work.But for this kind of electric pressure cooking saucepan, the distance between permanent magnet and tongue tube needs are arranged
Fairly close, tongue tube can just sense the magnetism of permanent magnet, for this purpose, limiting the distance of pot cover and jacket.And separate type
Gap between the pot cover and jacket of electric pressure cooking saucepan is larger, and the tongue tube being arranged on jacket can not delicately sense pot
Magnet in lid, therefore, tongue tube can not be realized delicately according to the actual conditions of closing lid in place and be powered or power off, and Voltage force is given
The use of pot is brought great potential safety hazard.
Invention content
In order to overcome the deficiencies of the prior art, the main object of the present invention is to provide a kind of simple in structure, easy to clean, performance
