As shown in Figure 1, according to the refrigeration plant of the embodiment of the present invention, comprising: casing 10, air door 20, stepper motor 30 and controller (not shown).
Specifically, be provided with air channel in casing 10, it is inner that the gas that the temperature that refrigeration plant produces is lower enters into casing 10 by air channel.Air door 20 is located at the wind passage mouth place in air channel, with when air door 20 is in primary importance, opens wind passage mouth; When air door 20 is in the second place, close wind passage mouth.The motor shaft 31 of stepper motor 30 is directly connected to drive air door 20 to change between the first position and the second position with air door 20.Controller to be located in casing 10 and to be connected with stepper motor 30.
According to the refrigeration plant of the embodiment of the present invention, adopt controller directly to stepper motor 30 pulse signal thus drive air door 20 to rotate.The pulse signal that controller sends is divided into drive singal and reset signal two kinds, and air door 20 is opened and closed more accurately.And the stepper motor 30 of self contained function drives air door 20 to rotate by motor shaft 31, make air door 20 action more flexibly, reliably.
As shown in Figure 1, according to one embodiment of present invention, one end of air door 20 is connected with the motor shaft 31 of stepper motor 30.The other end relative with motor shaft 31 of air door 20 can pivotable be connected with casing 10.When stepper motor 30 action, motor shaft 31 drives air door 20 to rotate, just can drive thus air door 20 open wind passage mouth primary importance and close wind passage mouth the second place between change.
As shown in Figure 1, according to one embodiment of present invention, the other end of air door 20 is provided with the rotating shaft 21 relative with motor shaft 31, and casing 10 is provided with the bearing (not shown) mated with rotating shaft 21.Rotating shaft 21 on casing 10, can realize the other end of air door 20 and can pivotable being connected of casing 10 by bearing assemble thus.
As shown in Figure 1, according to one embodiment of present invention, air door 20 can be rectangular slab, and motor shaft 31 and rotating shaft 21 are positioned at the top (direction such as shown in Fig. 1) of rectangular slab.
As shown in Figure 1, according to one embodiment of present invention, stepper motor 30 is fixed on casing 10 by fixed leg 32.Thus, stepper motor 30 more firmly can be assemblied on casing 10.It should be noted that, the installation site of stepper motor 30 can be changed, to meet the user demand of different user.
As shown in Figure 2, according to one embodiment of present invention, motor shaft 31 comprises: driving shaft 311 and resetting shaft 312.Particularly, driving shaft 311 is fixedly connected with air door 20.Resetting shaft 312 is socketed on driving shaft 311, and wherein resetting shaft 312 relies on the frictional force between driving shaft 311 to drive driving shaft 311 together to rotate.
As shown in Figure 2, according to one embodiment of present invention, the end face of the side of resetting shaft 312 offsets with the relative end face of driving shaft 311.There is frictional resistance between resetting shaft 312 and driving shaft 311, the size of its moment is greater than driving shaft 311 to drive torque required for air door 20, so that make air door 20 reset under the driving of reseting pulse signal.
As shown in Figure 2, according to one embodiment of present invention, stepper motor 30 is connected with controller by wire 40.Controller is directly connected by wire with stepper motor 30, such that the control law of air door 20 is simple, good stability.
When applying the pulse signal of forward to stepper motor 30, air door 20 is opened to be needed to turn 90 °, and at this moment stepper motor 30 is according to the angle φ often walking rotation, rotates corresponding step number n.When air door is closed, then need to an air door n+1 pulse, the reset that a unnecessary pulse is used for air door 20 is closed closely.Such as, when to open the step number needing stepper motor 30 to rotate be 20 to air door 20, so, when air door is closed, need to air door 20 21 pulse signals, a unnecessary pulse signal is used for the reset of air door 20.
The reset principle of air door 20 is as follows:
As shown in Figure 2, driving shaft 311 drives air door 20 to rotate, and has frictional resistance between driving shaft 311 and resetting shaft 312, and the size of its moment is greater than the torque of drive required for door-plate.Under air door 20 does not have resistant situation, air door 20 rotates under the drive of driving shaft 311; When air door 20 receives wind passage mouth stop, will relatively rotate between driving shaft 311 and resetting shaft 312, and under the effect of the frictional force between driving shaft 311 and resetting shaft 312, make air door 20 reset.
According to one embodiment of present invention, wind passage mouth can be air inlet or air outlet.According to one embodiment of present invention, refrigeration plant can be refrigerator, refrigerator or air-conditioning.
