Combine accompanying drawing below by detailed description of the invention the application is described in further detail.
Refer to Fig. 1, a kind of electric pressure cooking saucepan of this offer, including: lid and pot, lid and pot are in use in covering state, now can carry out heat foods process, when not covering tightly and cannot cover, now heat foods be may result in and occur that water dryouies and the potential safety hazard burnt.Therefore, the present embodiment provides the testing circuit ensureing electric pressure cooking saucepan use safety of correspondence accordingly.
Specifically, above-mentioned testing circuit includes: the magnet 1 that is arranged in lid, the Hall switch 2 being arranged in pot, and electrically connects with Hall switch 2 with the control chip 3 of the actuated signal control electric pressure cooking saucepan duty according to Hall switch 2.Wherein, magnet 1 can be Magnet.
It should be noted that, magnet 1 and Hall switch 2 are for detecting uncapping and closing lid of electric pressure cooking saucepan.When electric pressure cooking saucepan installs magnet 1 and Hall switch 2, it should remain that magnet 1 and Hall switch 2 are close when electric pressure cooking saucepan closing lid puts in place, and Hall switch 2 turns on.When electric pressure cooking saucepan is uncapped, magnet 1 separates with Hall switch 2, and Hall switch 2 disconnects.For existing electric pressure cooking saucepan folding type, magnet 1 is roughly divided into following three types with the installation site of Hall switch 2: one, magnet 1 is installed on pot cover, and Hall switch 2 is arranged in pot.Uncap and in the action of closing lid, Hall switch 2 is in relative static conditions, and magnet 1 is in relative motion state.Two, magnet 1 is arranged in pot, and Hall switch 2 is arranged on pot cover.Uncap and in the action of closing lid, Hall switch 2 is in relative motion state, and magnet 1 is in relative static conditions.Three, for electric pressure cooking saucepan folding lid being the mode of left rotation and right rotation, magnet 1 and Hall switch 2 are simultaneously located on pot cover, and when electric pressure cooking saucepan closing lid, magnet 1 is close with Hall switch 2 and Hall switch 2 turns on.When electric pressure cooking saucepan is uncapped, magnet 1 separates with Hall switch 2 and Hall switch 2 disconnects.
When electric pressure cooking saucepan closing lid, magnet 1 is close with Hall switch 2, and Hall switch 2 turns under the action of a magnetic field of magnet 1, and due to Hall switch 2 one end ground connection, the other end is connected with the pin of control chip U1.After Hall switch 2 conducting, the pin level of control chip U1 becomes low level.According to low level signal, control chip U1 knows that the pot of electric pressure cooking saucepan and pot cover fasten and put in place, i.e. electric pressure cooking saucepan closing lid is in ready state.When control chip U1 is simultaneously received heating signal, control chip can start heating to electric pressure cooking saucepan.When electric pressure cooking saucepan is uncapped, magnet 1 separates with Hall switch 2, and Hall switch 2 is departing from the magnetic field of magnet 1 generation and disconnecting, and the pin voltage of control chip U1 is high level.The pot and pot cover of knowing electric pressure cooking saucepan according to the high level signal of pin are not fastened and put in place by control chip U1, control electric pressure cooking saucepan and stop electric pressure cooking saucepan heating immediately.
So, when electric pressure cooking saucepan is in heating, magnet does not causes Hall switch to produce induced signal close to Hall switch, induced signal instruction lid does not covers with pot, now, control chip according to this actuated signal control electric pressure cooking saucepan not heating work, thus will avoid water in long-time heating causes pot and dryout and burn, it is ensured that electric pressure cooking saucepan uses safety.
In the present embodiment, Hall switch 2 one end is connected with control chip 3 by current-limiting resistance R1, other end ground connection.So, current-limiting resistance R1 can prevent control chip 3 from being impacted by big electric current, it is ensured that chip secure.
As another kind of embodiment, as in figure 2 it is shown, for the pin voltage strengthening the control chip being connected with Hall switch 2, Hall switch connects current-limiting resistance one end and is also coupled to working power Vcc.And usual, Hall switch 2 is connected to working power Vcc by a divider resistance R2.
As another kind of embodiment, as it is shown on figure 3, do not cover the purpose of warning with pot in order to reach lid, control chip 3 is also associated with an alarm 4.This alarm 4 sound alarm subsystem, such as buzzer, loudspeaker etc., it is also possible to be light crossing-signal, such as LED, or combined aural and visual alarm.
In the description of this specification, the description of reference term " embodiment ", " some embodiments ", " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means that the specific features, structure, material or the feature that combine this embodiment or example description are contained at least one embodiment or the example of the application.In this manual, the schematic representation to above-mentioned term is not necessarily referring to identical embodiment or example.And, the specific features of description, structure, material or feature can combine in any one or more embodiments or example in an appropriate manner.
Above content is to combine the further description that the application is made by specific embodiment, it is impossible to assert the application be embodied as be confined to these explanations.For the application person of an ordinary skill in the technical field, on the premise of conceiving without departing from the application, it is also possible to make some simple deduction or replace.
