Abstract
The invention relates to a freezer open alarm device. A membrane microswitch (1) and a membrane microswitch (2) are arranged on one side of doors of a freezing chamber and a refrigerating chamber, a loudspeaker (4) and a signal lamp (5) are arranged at other proper positions of the freezer, and a circuit board provided with a special voice integrated block (6) is mounted at a safe and concealed position. The membrane microswitches (1) and (2) are connected in parallel, and are in an open-circuit state under the action of the doors of the freezer when the doors of the freezer is closed, once one of the doors is opened, the corresponding switch is closed, and a voice module is electrified to drive the loudspeaker to produce voice and the signal lamp to light, thereby reminding people to close the doors.
Description
Technical field
The present invention relates to a kind of refrigerator-freezer, particularly a kind of freezer open alarm device.Belong to household electrical appliance technical field.
Background technology
Refrigerator-freezer is widely used household electrical appliance in restaurant, hotel, cold food sale and the family, such phenomenon is usually arranged in daily life: because careless and inadvertent, and the influence of other factors, sometimes usually wrong pass freezer door or the phenomenon that is not closed completely, this not only can waste electric energy, and the work that can cause compressor for freezer not stop thus, burn refrigerator-freezer, cause heavy losses.
Summary of the invention
For overcome that existing refrigerator-freezer exists because of mistake close the door or close the door the waste electric energy that sternly may not cause, burn the refrigerator-freezer phenomenon, the invention provides a kind of freezer open alarm device.
The technical scheme that a kind of freezer open alarm device adopted is: doorway one side at the freezing and refrigerating chamber of refrigerator-freezer, the circuit board that film microswitch (1) and film microswitch (2) are set respectively, at other suitable position of refrigerator-freezer loudspeaker (4) and signal lamp (5) are set, dedicated voice integrated package (6) will be installed is installed in refrigerator-freezer place safe and out of sight.Two film microswitches (1), (2) are in state in parallel, when freezer door closure state at ordinary times, under the effect of refrigerator-freezer, be in open-circuit condition, in case wherein a freezer door is opened, corresponding switch closure, the voice module energising, just promote the loudspeaker sounding, signal lamp is luminous, and reminds people is closed the door.
The invention has the beneficial effects as follows: reminds people is understood the closed condition of freezer door in time, prevents because of careless and inadvertent waste electric energy that causes and the accident of burning refrigerator-freezer.
Description of drawings
Accompanying drawing 1 is the layout drawings of electric elements on refrigerator-freezer.
Accompanying drawing 2 is circuit theory diagrams.
Shown in the figure: 1,2 film microswitches; 3 master switch; 4, loudspeaker; 5, signal lamp; 6, voice integration module; 7, power supply.
The specific embodiment
Doorway one side at the freezing and refrigerating chamber of refrigerator-freezer, the circuit board that film microswitch (1) and film microswitch (2) are set respectively, at other suitable position of refrigerator-freezer loudspeaker (4) and signal lamp (5) are set, dedicated voice integrated package (6) will be installed is installed in refrigerator-freezer place safe and out of sight.Two film microswitches (1), (2) are in state in parallel, when freezer door closure state at ordinary times, under the effect of freezer door, be in open-circuit condition, in case wherein a freezer door is opened, corresponding switch closure, the voice module energising, just promote the loudspeaker sounding, signal lamp is luminous, and reminds people is closed the door.
