Abstract
The utility model discloses an automatic control device for a microwave oven. The automatic control device comprises a conversion micro-switch, a controller and a main control chip device, wherein the controller is used for controlling the microwave oven to work; the main control chip device is arranged in the controller; a signal processing chip unit is also arranged in the controller; a temperature sensor is connected onto the signal processing chip unit; the main control chip device is connected with a power supply through the conversion micro-switch connected with the main control chip device in series; the automatic control device further comprises an electronic execution component matched with the controller; the electronic execution component is connected with the temperature sensor through the signal processing chip unit; information acquired by the temperature sensor is transmitted to the main control chip device by the signal processing chip unit; when the temperature is gradually reduced, the main control chip device for the microwave oven controls the on/off of the conversion micro-switch by the electronic execution component. When the automatic control device disclosed by the utility model works, the microwave oven can automatically turn off a power supply even if the power supply is not be manually disconnected, so that energy sources are effectively saved and the convenience and higher cost performance are brought to users.
Description
Technical field
The utility model relates to electrical appliances intelligent control technical field, is specially a kind of micro-wave oven automaton.
Background technology
Can not auto-breaking after current cooking in microwave oven work completes, must be by manually pulling out attaching plug or powered-down switch is cut off the electricity supply, otherwise micro-wave oven will be always in "on" position, continues to consume electric energy.Therefore, be necessary to design a kind of micro-wave oven of automatic control, to meet actual needs.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of micro-wave oven automaton, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of micro-wave oven automaton, comprise change type microswitch switch, control the controller of micro-wave oven work, be arranged on the main control chip device in controller, in described controller, be also provided with signal processing chip unit, described signal processing chip is connected with temperature sensor on unit, described main control chip device is connected with power supply by the change type microswitch switch of connecting with it, also comprise the electronics execution unit mating with controller, described electronics execution unit is connected with temperature sensor by signal processing chip unit, communication temperature sensor being gathered by signal processing chip unit is to main control chip device, when temperature reduces gradually, micro-wave oven main control chip device is by connection and the disconnection of electronics execution unit control change type microswitch.
Preferably, described electronics execution unit is relay or the wireless launcher that control circuit interrupts.
Preferably, described power supply is AC power.
Compared with prior art, it has following beneficial effect to the utility model:
The utility model is used for the structure of automatic cut-off power by increasing an electronics execution unit, micro-wave oven main control chip device is realized the control of auto-breaking, after user uses micro-wave oven, also can make micro-wave oven automatically cutting off power source even if do not pull out by hand power supply, thereby effectively save the energy, bring advantage to the user and better cost performance.
Brief description of the drawings
Fig. 1 is circuit diagram of the present utility model.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of micro-wave oven automaton as shown in Figure 1, comprise change type microswitch switch 1, control the controller 2 of micro-wave oven work, be arranged on the main control chip device 4 in controller 2, in described controller 2, be also provided with signal processing chip unit 5, on described signal processing chip unit 5, be connected with temperature sensor 6, described main control chip device 4 is connected with power supply by the change type microswitch switch 1 of connecting with it, also comprise the electronics execution unit mating with controller, described electronics execution unit is connected with temperature sensor 6 by signal processing chip unit 5, communication temperature sensor being gathered by signal processing chip unit 5 is to main control chip device 4, when temperature reduces gradually, micro-wave oven main control chip device 4 is by connection and the disconnection of electronics execution unit control change type microswitch 1.
When described electronics execution unit is and the relay 3 being arranged on controller, main control chip device 4 contactings of control relay 3 and the signal output part of disconnection are connected with relay 3, and relay 3 is connected with power supply.
After user puts cooking food micro-wave oven into and closes upper furnace door, microswitch is transformed into major loop, and SW-L holds disconnection.Controller is powered by closed relay 3.Now, user can start micro-wave oven by operation control panel and carry out cooking work.After end of cooking, user takes out after food, and the temperature that temperature sensor 6 gathers reduces gradually, at this moment automatically controller power source is disconnected by main control chip device 4 control relays 3, thereby realizes micro-wave oven auto-breaking.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
