Embodiment Construction

[0011] Combined with the accompanying drawings, a new type of digital display intelligent instrument, its fan failure alarm and automatic power-off system includes a fan 1 connected to a fuse 2, a fuse 2 connected to a current transformer 3, a current transformer 3 connected to a microcomputer controller 4, and a microcomputer The controller 4 is connected with the alarm 5 and the relay 6, and the relay 6 is connected with the fan 1 and the external power supply 7.

[0012] During the actual use of this new type of digital display intelligent instrument, if the fan 1 fails, the fuse 2 is disconnected, the current transformer 3 senses an abnormal current, and the abnormal signal is transmitted to the microcomputer controller 4, and the microcomputer controller 4 starts an alarm Device 5 sends an alarm signal. At the same time, the microcomputer controller 4 transmits a signal to make the relay 6 disconnect the external power supply 7, thereby automatically powering off the blow...

Abstract

The invention discloses a novel digital display intelligent instrument, in particular to a special digital display intelligent instrument used for an electric warm air blower and a unit. The novel digital display intelligent instrument is provided with a blower fault warning and automatic power-off system. The novel digital display intelligent instrument is characterized in that the blower and a protective tube are connected in series, and connected with a relay, the relay is connected with an external power source and a microcomputer controller, and meanwhile the microcomputer controller is connected with an alarm and a current transformer. One end of the current transformer is connected with the microcomputer controller, and the other end of the current transformer is connected with a blower circuit. The novel digital display intelligent instrument has the advantages that when the novel digital display intelligent instrument is used for the electric warm air blower, if the blower breaks down, the protective tube will be switched off, the current transformer senses abnormity of a current and transmits the abnormity to the microcomputer controller, the microcomputer controller starts the alarm, the relay is disconnected with the external power source under the control of the microcomputer controller, and the blower is powered off. Dangerous accidents are avoided.

Description

technical field [0001] The invention relates to a novel digital display intelligent instrument with simple structure and strong functionality, in particular to a novel digital display intelligent instrument, which is mainly suitable for electric heaters and unit instruments. Background technique [0002] In today's society, electric heaters have been widely used in various places. However, since the electric heater came out, there have been many accidents caused by our improper use or the failure of the machine itself, some of which may cause fires, and some of which may hurt lives, which have brought great harm to people. The use safety of electric heaters must be improved to ensure the safety of people's lives and property. For this reason, the present invention has designed a kind of novel electric heater and the special digital display intelligent instrument of unit. Contents of the invention [0003] The purpose of the present invention is to provide a new type of d...
