Background technology
Electric heating boilers such as electric cooker, electromagnetic oven etc. are clean, sanitary with it, advantage is more and more easily and efficiently gets their way into people's lives, but the excessive pot problem that produces in heating process is then perplexing people often.People have invented anti-overflow kitchen range and its corresponding pan (as Chinese utility application number 200420049480.2 patent names: the anti-overflow pot) for this reason, it is to utilize two anti-overflow contacts are set on the electric heating kitchen range, and by constituting and (anti-flow electrode only is set on pot cover usually and is electrically connected in that the anti-flow electrode be electrically connected with this anti-overflow contact being set on the pot cover with one of them anti-overflow contact, another anti-overflow contact then is electrically connected with the pot body usually), wherein anti-flow electrode stretches in pan, and it stretches in the pan mouth usually.Its operation principle is, when the liquid in the pan has when overflowing, the anti-flow electrode on its pot cover can contact with the foam that overflows earlier, thus by with kitchen range that it is electrically connected in controller detect, and kitchen range are taken appropriate measures, as stop to heat etc.
But, the anti-flow electrode of this anti-overflow pan is arranged in the pot cover (it is electrically connected with anti-overflow contact on the kitchen range by the handle on the pot cover) by insulating materials, along with constantly increasing of kettle temperature, water vapour in the pan also more and more accumulates on the pot cover, even nonmetal like this pot cover also can cause the false pot that overflows.And since anti-flow electrode normally along with the position of handle is arranged in the middle of the pot cover; and because pot cover is airtight; the foam that has overflow when overflowing pot usually can be earlier begins to excessive from the circumference of pan; thereby make easily and can not in time monitor the pot that overflows, and the length that stretches in the pot by the adjustment anti-flow electrode also can't solve.
Summary of the invention
For overcoming above-mentioned defective, the invention provides a kind of anti-overflow pot that plays real anti-overflow purpose.
For achieving the above object, the anti-overflow pot cover of band passage of the present invention, comprise lid and the anti-flow electrode that is electrically connected with the anti-overflow control section test side of electric heating kitchen range, described lid is provided with the passage of a diameter greater than anti-flow electrode, and described anti-flow electrode is arranged in the passage and with lid and does not contact.
After adopting said structure, make anti-flow electrode be arranged on the outside of pot cover body, and do not contact with the passage on the lid, therefore can prevent the false pot that overflows effectively, and because the setting of passage, when overflowing pot, the foam that has overflow can be filled with to the passage place earlier, thereby can solve the inaccurate problem of pot of overflowing of monitoring preferably.
The specific embodiment
See figures.1.and.2, the anti-overflow pot cover of band passage of the present invention, comprise lid 1 and the anti-flow electrode 2 that is electrically connected with the anti-overflow control section test side of electric heating kitchen range, described lid 1 is provided with the passage 3 of a diameter greater than anti-flow electrode, and described anti-flow electrode 2 is arranged in the passage 3 and with lid 1 and does not contact.
Above-mentioned anti-flow electrode 2 can be determined its connected mode according to the anti-overflow control section test side in the electric heating kitchen range and the connected mode of pot body, when pan is the metal pan, its anti-flow electrode can one be connected on pot body, another is arranged on a pot body top, needs only a passage like this on the lid; And this is made as nonmetallic materials when the pot body or consider metal pan oxidation and cause and connect bad reason, also two anti-flow electrode all can be arranged on a pot body top, at this moment, a passage can be set on the lid, and two anti-flow electrodes are arranged in the passage, two passages also can be set, two anti-flow electrodes are separately positioned on wherein.(being an anti-flow electrode among the figure)
As shown in the figure, on the pot cover of passage one side, be provided with a handle 4, described anti-flow electrode 2 is arranged on the handle 4, leaves the space between the handle 4 of described anti-flow electrode 2 one sides and the lid 1 at passage place, so that the steam in the pan is run out of from passage.
Above-mentioned handle 4 can strip, and it can be provided with the pot cover center by an end, in order to the installing anti-flow electrode; The other end then stretches out to pot cover edge, and the position suitable with the anti-overflow control section test side of electric heating kitchen range is provided with electrical pickoff 21.Certainly, also can make the strip handle in its one or both ends the electrical pickoff that is electrically connected with anti-flow electrode is set across whole pot cover as a kind of distortion.Above-mentioned handle also can be the T font.
Above-mentioned passage 3 can be arranged on any part of pot cover, as is arranged on the pot cover center, or in edge of lid etc.
When passage 3 is provided with in edge, can establish a depression at lid 1 edge, when pot cover covered on pot, this depression also can form passage with a pot body.Anti-flow electrode 2 can be provided with by the form of above-mentioned handle on the pot cover of this structure, also can be arranged on one with pot cover suitable the pot body on, being about to anti-flow electrode is arranged on pot body one side by insulation such as plastics, bakelites and is the shape of falling J, its anti-overflow test side is arranged in the passage, and does not contact with lid and to get final product.
As improvement of the present invention, be provided with a circular form of making by glass at described lid, described passage 3 is arranged on the form.So not only can not lift pot cover and just can see the process of food heating, and, can further increase insulation effect because glass is insulating materials.
Form short circuit for the steam that prevents to run out of divides grip and pot cover metal part from passage, be provided with projection 6 towards the position of passage one side towards lid at described handle.
