Along with science and technology development, electrical equipment enters the every field of mankind's activity more and more.Continuous increase along with appliance power, particularly in the household electrical appliance, high-power household electrical appliance such as the roller washing machine of air conditioner, microwave oven, electric heater, band heating or oven dry, drying cupboard, dishwasher enter family, supply socket is as the access port of many electrical equipment access power supplies, and its failure rate also highly rises.The user of electrical equipment, particularly domestic consumer seldom specially observe the supply socket situation.When the supply socket power of selecting does not reach the load power that electrical equipment requires, the inner loose contact of socket, poor quality or other reason cause temperature constantly to rise, and burn supply socket, attaching plug and power line, even initiation fire.The electrical equipment manufacturer can check or require user's supply socket safe in utilization at the most in the electrical equipment process that provides for user installation oneself.But along with use increases, user's supply socket may be worn out or accidental damage; The user also may transfer to electrical equipment in other problematic supply socket and use.
For security appliance and performance performance; in the electrical equipment that uses single-phase alternating current; generally adopt a kind of supply line of common recognition; and in supply socket, also be provided with the arrangement of the polarity common recognition of phase line, zero line, ground wire; can provide good ground protection to the electrical equipment that uses like this; performance such as anti-interference is better brought into play, also be convenient to Electrical Appliances Designing person and near end, the ground path of coil are chosen earth point etc. design etc.But a lot of users often can not grasp the polarity arrangement situation in the supply socket, and many users have also destroyed original correct polarity arrangement among finishing.
Though at the most of devices that all are provided with power protection of present electric equipment products, also lack a kind of supply socket intensification supervising device of a kind of energy energy instant alerts user, yet there are some defectives in the device of more existing protection supply sockets:
At first, the existing power supply protective device mostly is so that blindly turn-offing electric operation protects power supply, can not be according to user's will disposition.Such as: under the unwitting situation of user, closed fowl ovum incubator; Under a certain state of washing machine, close washing machine operation, clothing can't be got; Under the situation that does not have the unloading data, shut down computer or the like.
Secondly, mostly lack the whether correct device of polarity wiring in the identification user supply socket in the existing electrical equipment.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective provides a kind of attaching plug with temp monitoring function, and whether this plug can monitor user's supply socket has the temperature of exceeding the quata and electric power polarity to arrange whether correct also instant alerts user.
For achieving the above object, the present invention adopts following technical scheme:
A kind of attaching plug with temp monitoring function, comprise housing, patch sheet and electric power connection line bundle, it is characterized in that, also comprise the device for detecting temperature monitor controller, described electric power connection line bundle comprises at least one auxiliary connection, and described device for detecting temperature is connected with monitor controller by auxiliary connection.
Above-mentioned attaching plug is characterized in that, also comprises phase lamp in the described monitor controller, and this monitor controller is arranged in the plug, or is arranged on electrical appliance inside.
Above-mentioned attaching plug is characterized in that, described phase lamp comprises the red light that shows the green light that live wire connects and show the zero line misconnection, and described green light is connected between live wire and the zero line, and described red light is connected between zero line and the ground protection line.
Above-mentioned attaching plug is characterized in that, described device for detecting temperature is a temperature sensor or temperature detect switch (TDS), and it is arranged in the plug casing, is connected with monitor controller by auxiliary connection.
Above-mentioned attaching plug is characterized in that, described monitor controller is provided with the holding wire of an intervention electrical control circuit, and wiring state signal and temperature signal are got involved the inner original control model of electrical equipment.
Above-mentioned attaching plug is characterized in that, also is provided with alarming horn or alarm lamp in the described monitor controller.
Above-mentioned attaching plug is characterized in that, an overtemperature relay is set in the described monitor controller, by the protection switch of this relay control connection on power firestreak.
Above-mentioned attaching plug is characterized in that, described protection switch is a delay switch.
Above-mentioned attaching plug is characterized in that, this plug can be two slotting, three slotting, four slotting or other forms of power supply connected modes.
The invention has the beneficial effects as follows: used a kind of easy mode, electrical equipment is independently monitored the supply socket that self connects immediately, directly power cutoff prevents the accident that supply socket causes, and particularly prevents trouble before it happens for fire incident; Simultaneously, this plug can also be used to examine employed supply socket back panel wiring, effectual protection ground wire whether, and whether live wire and zero line phase place connect reciprocity situation in the socket; This plug that has temp monitoring function can allow the user according to circumstances in time take measures, rather than power cutoff blindly protects, and can avoid some unnecessary loss.Below in conjunction with the drawings and specific embodiments technical solution of the present invention is described further.
