User is unfavorable for effective popularization of clothes airing machine to the degree of recognition of clothes airing machine.
Utility model content
The purpose of this utility model is to provide a kind of anti-impact circuit applied on clothes airing machine, to solve clothes airing machine rising
Operation declines the problem of impact that operation produces influences.
The technical scheme in the invention for solving the above technical problem is：
A kind of anti-impact circuit, including switch power module, lifting motor and be serially connected in the switch power module and
Protection device between the lifting motor；The switch power module is used to power for the lifting motor, the lifting electricity
Machine provides the power for rising or falling operation for clothes-horse, described to protect device to obstruct the potential that the lifting motor produces
Impact signal is transmitted to the switch power module.During so as to fulfill rising in lifting motor, declining or rise and fall
Surge protection of the switchover operation to switch power module.
Further, the anti-impact circuit further include be serially connected in it is described protection device and the lifting motor between after
Electric appliance.The relay is used to control the lifting motor to make clothes-horse rise or fall operation.
Further, the anti-impact circuit further includes the drive module for controlling the relay.
Further, the output terminal of the drive module is connected with the input terminal of the relay.
Further, the anti-impact circuit further includes the MCU controllers for driving the drive module.
Further, the input terminal of the MCU controllers is connected with the output terminal of the switch power module.
The utility model also provides a kind of electric clothes airing machine for including above-mentioned anti-impact circuit.
To sum up, the beneficial effects of the utility model are：Anti-impact circuit described in the utility model, due to protection device
Increase, impact signal can not protect the device of Switching Power Supply and the safety of circuit by protecting device to reach Switching Power Supply end,
Can effectively prevent motor causes potential impact to cause controller due to rising operation, decline operation or rise and fall switchover operation
Damage, the performance safety of lifting controller.
Brief description of the drawings
Fig. 1 is the circuit block diagram shown in the utility model preferred embodiment；
Fig. 2 is the anti-impact circuit schematic diagram shown in the utility model preferred embodiment.
Embodiment
With reference to embodiment and attached drawing, the utility model is described in further detail, but the reality of the utility model
Apply mode not limited to this.
Embodiment 1
Referring to Fig. 1, a kind of anti-impact circuit shown in the utility model preferred embodiment, including switch power module,
Protect device, relay, drive module, MCU controllers and lifting motor；220V alternating currents are connected with switch power module, switch
Power module output multi-channel voltage, voltage supply is provided for MCU controllers and lifting motor；Switch power module exports U1 voltages
Supply lifting motor does rising operation and declines operation and uses；Switch power module exports 5V power supply voltage supplying MCU controllers
Use.MCU controllers receive remote controller signal, and clothes airing machine rises or falls command signal according to what remote control was sent, and transmission refers to
Make to drive module, drive module driving relay control lifting motor carries out rising or falling operation, motor rising or under
Drop in operational process, since lifting motor is when operation, decline operation or rise and fall operation switching is risen, lifting
The input end position of motor, which produces very big voltge surge, to be influenced, protection device be serially connected in switch power module and relay it
Between, when lifting motor both ends produce impact signal, this impact signal is transferred to relay end input terminal, due to protection device
Increase, impact signal can not protect the device of Switching Power Supply and the safety of circuit by protecting device to reach Switching Power Supply end,
Can effectively prevent motor causes potential impact to cause controller due to rising operation, decline operation or rise and fall switchover operation
Damage, the performance safety of lifting controller.
The anti-impact circuit schematic diagram of embodiment as shown in Figure 2, REL2 and REL3 in order to control motor rise operation or under
The relay of operation drops.R43 and CX5 composition absorption circuits, for absorbing the harmonic interference signals of motor generation；L2 is common mode electricity
Sense, M are lifting motor, and L2 can effectively suppress common mode interference and the spike interference of motor generation, prevent motor from being transported in lifting
Damage of the impact that row or lifting switching produce to control panel.As shown in Fig. 2, if motor produces strong punching at the both ends of CN4
When hitting electromotive force, if the voltage of 1 foot of the potential voltage of CN4 more than L2 and 2 feet, L2 can prevent 1 foot and 2 that harmonic wave enters L2
The both ends of foot, part do not consider the position that the harmonic wave removed can reach the F points of REL2 and REL3, and D10 is diode, the present embodiment
D10 uses SB5200, and in the presence of the surge voltage of F points, due to the unilateral conduction of D10, impact potential will not be switched toward U1
Power module direction play, D10 play the role of partition impact.Wherein R45 is current sense resistor, and EC12, C22 are filtered electrical
Hold, consider except detection port harmonic wave, R48, D13 and D14 are protection device, protect Test ports to be influenced from the impact of big voltage,
R44 and D11 declines current-limiting resistance for motor, reduces speed when lifting motor declines operation.
The utility model also provides a kind of electric clothes airing machine for including above-mentioned anti-impact circuit.
To sum up, a kind of anti-impact circuit shown in the application, due to protecting the increase of device, impact signal can not pass through guarantor
Protect device and reach Switching Power Supply end, protect the device of Switching Power Supply and the safety of circuit, can effectively prevent motor due to rising
Operation, decline operation or rise and fall switchover operation cause potential impact damage, property of lifting controller caused by controller
Can safety.
As described above, it can preferably realize the utility model.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, according to the technical essence of the utility model, within the spirit and principles of the present invention, above example is made
Any simple modification, equivalent substitution with improving etc., still fall within the protection domain of technical solutions of the utility model.
