Abstract
The utility model discloses a refrigerator door state alarm device, and belongs to the electric refrigerator field. The alarm device comprises an alarm composed of an integrated voice block, a loudspeaker mutually matched with the integrated voice block and a switch, the alarm is arranged on a casing at the position of a refrigerator door, a dry spring pipe is connected in an alarm circuit in series, the alarm device also comprises a permanent magnet corresponding to the alarm and arranged on a refrigerator door, and the dry spring pipe is matched with the permanent magnet to form an alarm switch. Because of adopting the technical proposals, when the refrigerator door is closed, the permanent magnet draws away an elastic piece of the dry spring pipe through a magnetic force, the normal close contact of the dry spring pipe is broken, and a circuit does not make an alarm sound; when the refrigerator door is not tightly closed, the magnetic force of the permanent magnet is not enough to break the normal close contact of the dry spring pipe, an alarming circuit is closed, and the alarm device alarms, to remind persons of continuously closing the refrigerator door. The refrigerator door state alarm device has the advantages that the structure is simple, the manufacturing cost is low, as well as the installation and the operation are convenient.
Description
Technical field
The utility model relates to the refrigerator technical field.It specifically is a kind of refrigerator doors status alert device.
Background technology
At present, the refrigerator that uses in the life, the general status alert device that does not all have door.If door of refrigerator is not closed completely, the work that will cause compressor not stop both wasted energy, and caused the damage to compressor, had reduced refrigeration or refrigerating effect again.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of refrigerator doors status alert device is provided.When refrigerator doors is not closed completely, can send reminding alarm sound.
The utility model is realized with following technical scheme: a kind of refrigerator doors status alert device, comprise the alarm of forming by integrated speech piece and the loudspeaker that is complementary with it and switch, it is characterized in that: alarm is installed on the housing at place, refrigerator doorway, series connection one dry reed tube in the alarm circuit, also comprise the permanent magnet corresponding with alarm that is installed on the refrigerator doors, dry reed tube cooperates with permanent magnet forms alarm switch.The switch contact of described dry reed tube is a normally closed type.
Owing to adopted technique scheme, when refrigerator doors was closed, permanent magnet drew back the shell fragment of dry reed tube by magnetic force, the normally closed contact disconnection of dry reed tube, and circuit does not send chimes of doom; When refrigerator doors was not closed completely, permanent magnet magnetic force was not enough to disconnect the normally closed contact of dry reed tube, the warning circuit closure, and warning device is reported to the police, and reminds the people to continue closing refrigerator door.
The beneficial effects of the utility model are: simple in structure, low cost of manufacture is is conveniently installed and used.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model electrical schematic diagram;
Fig. 2 the utility model is installed in the synoptic diagram on the refrigerator.
Among the figure: 1, refrigerator, 2, refrigerator doors, 3, alarm, 4, permanent magnet, 5, tongue tube, 6, the integrated speech piece, 7, loudspeaker, 8, triode, 9, battery.
Embodiment
As shown in Figure 1, warning part reaches the loudspeaker 7 and the tongue tube 5 that are complementary with it by integrated speech piece 6, triode 8, battery 9 and forms., this part is a mature technology, so ominous stating.Switch comprises that also alarm is installed on the housing at place, refrigerator doorway, and series connection one dry reed tube also comprises permanent magnet 4 in the alarm circuit.Tongue tube 5 is installed in the permanent magnet corresponding with alarm on the refrigerator doors, and dry reed tube cooperates with permanent magnet forms alarm switch.The switch contact of described dry reed tube 5 is a normally closed type.The magnetic field intensity of permanent magnet 4 designs as required, and promptly when refrigerator doors was closed, permanent magnet leaned on magnetic force can draw back the shell fragment of tongue tube, and the normally closed contact of tongue tube disconnects; When refrigerator doors was not closed completely, permanent magnet magnetic force can not disconnect the normally closed contact of dry reed tube and be advisable.
As shown in Figure 2, alarm 3 is contained in the inboard on refrigerator 1 doorway, and tongue tube 5 is contained on refrigerator doors 2 and the alarm 3 corresponding positions.
Claims (2)
