Detailed Description
The invention provides a wiring circuit of a wall fan motor, which is used for making the purpose, the technical scheme and the effect of the invention clearer and more definite, and the invention is further described in detail below by referring to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 2, the present invention provides a wiring circuit of a wall fan motor, which includes a synchronous motor 13, a control switch 15, a multi-stage speed regulating switch 11, a live wire end L, a neutral wire end N, a capacitive motor 12, a first closed terminal 142, a second closed terminal 141 and a third closed terminal 143, wherein multi-stage static switching contacts of the multi-stage speed regulating switch 11 are sequentially and correspondingly connected to a plurality of input ends of the capacitive motor 12, an input end of the multi-stage speed regulating switch 11 is connected to the live wire end L, one end of the synchronous motor 13 is sequentially connected to the control switch 15 and a synchronous motor connecting contact C of the multi-stage speed regulating switch 11 through the first closed terminal 142, the other end of the synchronous motor 13 is connected to an input end of a thermal fuse 124 of the capacitive motor 12 through the second closed terminal 141, and an output end of the thermal fuse 124 of the capacitive motor 12 is connected to the neutral wire end N through the third closed terminal 143. The neutral terminal N and the live terminal L are connected to a plug 16. When the electric motor is in an electrified state, the output end of the capacitive motor is connected with the output end of the synchronous motor, the thermal fuse is connected in series, the synchronous motor and the capacitive motor are simultaneously protected by the thermal fuse, when the temperature is higher than the highest temperature of the thermal fuse, the thermal fuse is disconnected, the capacitive motor can stop working to obtain overheat protection, in addition, the synchronous motor also stops working, because the capacitive motor is responsible for driving the fan blade to rotate, the synchronous motor is responsible for driving the steering of the wall fan, when the capacitive motor fails and does not work, the synchronous motor should be closed at the same time, the synchronous motor is prevented from continuing working (doing idle work) under the condition that the capacitive motor does not work, a large amount of electric energy is consumed, and the electric motor has the theme of saving energy and protecting environment against the current. On the other hand, in the operation of penetrating the electric wire into the electric wire sheath, only one electric wire sheath is needed to wrap the input electric wire (the electric wire between the first closed-end connecting terminal 142 and the control switch 15) of the synchronous motor, the input electric wire (the electric wire between the auxiliary winding and the static switching contact of the multi-gear speed regulating switch) of the capacitive motor and the output electric wire (the electric wire between the thermal fuse and the third closed-end connecting terminal) together, so that insulation protection is realized, a large amount of use of the electric wire sheath is saved, the workload of penetrating the electric wire into the electric wire sheath is reduced, and the working efficiency is improved.
Specifically, the multi-speed regulating switch 11 is a three-speed regulating switch. As shown in fig. 2, the access contact 0 of the multi-speed switch 11 is connected to the live wire end L, the stationary switching contact 1 is connected to the contact c of the secondary winding 122 of the capacitive motor 12, the stationary switching contact 2 is connected to the contact b of the secondary winding 122 of the capacitive motor 12, and the stationary switching contact 3 is connected to the contact a of the secondary winding 122 of the capacitive motor 12. When the knob of the multi-gear speed regulating switch is rotated to a high gear of wind speed, the static switching contact 3 is communicated with the access contact 0, and the capacitive motor runs at a high speed to drive the fan blade to rotate; when the knob of the multi-gear speed regulating switch is rotated to a middle gear of wind speed, the static switching contact 2 is communicated with the access contact 0, and the capacitive motor runs at a medium speed to drive the fan blade to rotate; when the knob of the multi-gear speed regulating switch is rotated to a low gear of wind speed, the static switching contact 1 is communicated with the access contact 0, and the capacitive motor runs at a low speed to drive the fan blade to rotate. The synchronous machine can only be activated by closing the control switch 15 when the access contact 0 is connected to one of the stationary switching contacts.
Specifically, the capacitive motor 12 includes a main winding 123, a start capacitor 121, a thermal fuse 124, and a secondary winding 122; the first end of the auxiliary winding 122 is connected to the first end of the main winding 123, the second end of the auxiliary winding 122 is sequentially connected to the starting capacitor 121 and the second end of the main winding 123, the auxiliary winding 122 is sequentially connected to the multi-gear static switching contact of the multi-gear speed regulating switch 11, and the second end of the main winding 123 is connected to the input end of the thermal fuse 124.
In summary, the invention provides a wiring circuit of a wall fan motor, which has the advantages of simple wiring, wire sheath saving and cost reduction compared with the prior art. One end of the synchronous motor is connected to the contact point of the thermal fuse and the starting capacitor, the thermal fuse is used for protecting the capacitor motor from overheating and burning out, and after the thermal fuse is burned out, the synchronous motor can stop working due to power failure, so that the synchronous motor is protected, meanwhile, electricity is saved, and the current energy-saving and environment-friendly theme is met. In addition, the ingenious circuit connection design only needs to use one wire sheath, the input wire and the output wire of the capacitive motor and the input wire of the synchronous motor are wrapped together, and a large number of wire sheaths can be saved in the manufacturing process, so that the material cost of enterprises is reduced, the workload of penetrating the wires into the wire sheaths is reduced, and the productivity is improved.
