Abstract
The utility model discloses a key-switch type toaster controller. The key-switch type toaster controller comprises a power supply and an electromagnet. The key-switch type toaster controller is characterized by also comprising a key switch, an armature, an IC (integrated circuit) control chip and a timer which are connected, wherein the armature is positioned above the electromagnet; and when the electromagnet attracts the armature, the power supply, the electromagnet, the key switch, the armature, the IC control chip and the timer form a switching-on loop. When the electromagnet can attract the armature, the timer can calculate the heating time accurately, the armature is attracted or released by the electromagnet, and the key switch is switched on or switched off. The key-switch type toaster controller disclosed by the utility model has the advantages that the switching on and switching off of a circuit is controlled by using the electromagnet to attract the armature, so that the risk for generating electric arc is avoided, the safety degree is higher, the use is convenient and the circuit working is more reliable.
Description
Technical field
The utility model relates to the controller that is used for toaster, particularly a kind of keyswitch formula toaster controller.
Background technology
Toaster is often referred to automatic rusk baking oven, toaster, is a kind of electric-heating cooking utensil that toasts.What existing toaster controller generally used is the control of spring contact formula, has the risk that produces electric arc, and security is not high.Like the license notification number is the disclosed toaster controller of CN2831408Y; Comprise solenoid driver circuit; What this solenoid driver circuit adopted is the control of spring contact formula, is prone to when two contact distance are nearer produce because the electric arc that atmospherical discharges produces can damage whole device when serious.
The utility model content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of keyswitch formula toaster controller, through the break-make of keyswitch control circuit, has avoided producing the risk of electric arc, and degree of safety is higher, and is easy to use.
To achieve these goals, the technical scheme of the utility model is following:
Keyswitch formula toaster controller; Comprise power supply and electromagnet; Be characterized in; Also comprise keyswitch and the armature, IC control chip and the timer that link to each other, said armature is positioned at the electromagnet top, and said power supply, electromagnet, keyswitch, armature, IC control chip and timer constitute a conducting loop.
Further, said keyswitch one end connects armature, other end connection timer, and said timer connects the IC control chip again, and said IC control chip connects power supply, and said power supply connects electromagnet, and electromagnet can adsorb the armature of top, makes the conducting of whole loop.
Said timer can accurately calculate heat time heating time, and can signal heat time heating time be transferred to the IC control chip, and said IC control chip can be given the electromagnet release signal, and said armature is through electromagnetic actuation or release, makes keyswitch conducting or disconnection.
The action principle of the utility model is,
Above-mentioned armature is pressed it contact with electromagnet under the effect that the external force people handles, and timer picks up counting simultaneously, and toaster begins to heat, and entire circuit is in conducting state at this moment, and timer is started working;
The heating timing time that is provided with arrives, and the IC control chip is given the electromagnet release signal, and electromagnet discharges armature, and keyswitch just is in off-state like this.
The beneficial effect of the utility model is, external force only need be handled once, can control whole process, through the break-make of keyswitch control circuit, avoided producing the risk of electric arc, and degree of safety is higher, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment:
For the creation characteristic, the technological means that make the utility model and reach purpose and be easy to understand and understand, further set forth the utility model below in conjunction with specific embodiment.
Embodiment:
Referring to Fig. 1, keyswitch formula toaster controller comprises electromagnet 1, power supply 2, IC control chip 3, timer 4, keyswitch 5 and the armature that links to each other 6; Armature 6 is connected with an end of keyswitch 5 mutually, the other end connection timer 4 of keyswitch 5, and timer 4 connects control chip 3 again; Control chip 3 connects power supply 2; Power supply 2 connects electromagnet 1, and promptly electromagnet 1, power supply 2, IC control chip 3, timer 4, keyswitch 5 constitute a complete loop with the armature that links to each other 6, wherein; Armature 6 must be positioned at said electromagnet 1 top and link to each other with keyswitch 5, and power supply 2, IC control chip 3 and timer 4 adjustable positions are changed.
The action principle of the utility model is,
Above-mentioned armature 6 is pressed it contact with electromagnet 1 under the effect that the external force people handles, and timer 4 picks up counting simultaneously, and toaster begins to heat, and entire circuit is in conducting state at this moment, and timer 4 is started working;
The heating timing time that is provided with arrives, and IC control chip 3 is given the electromagnet release signal, and electromagnet 1 discharges armature 6, and keyswitch 5 just is in off-state like this.
The utility model external force only need be handled once, can control whole process, through the break-make of keyswitch control circuit, has avoided producing the risk of electric arc, and degree of safety is higher, and is easy to use.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
