As shown in Figure 1, the refrigeration plant according to the embodiment of the present invention, comprising: casing 10, air door 20, stepper motor 30 and controller (not shown).
Particularly, in casing 10, be provided with air channel, the lower gas of temperature that refrigeration plant produces enters into casing 10 inside by air channel.Air door 20 is located at the wind passage mouth place in air channel, during in primary importance, to open wind passage mouth at air door 20; At air door 20, during 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 primary importance and the second place with air door 20.Controller is located in casing 10 and is connected with stepper motor 30.
According to the refrigeration plant of the embodiment of the present invention, thereby adopt controller directly to stepper motor 30 pulse signals, to drive air door 20 to rotate.The pulse signal that controller sends is divided into and drives two kinds of signal and reset signals, and air door 20 is opened and closed more accurately.And the stepper motor 30 of self contained function is by motor shaft 31 drive air doors 20 rotations, makes air door 20 actions more flexible, reliable.
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 doors 20 to rotate, and just can drive thus air door 20 opening the primary importance of wind passage mouth and closing between the second place of wind passage mouth and 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) mating 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 (example is direction as shown in Figure 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, wherein resetting shaft 312 rely on and driving shaft 311 between frictional force drive driving shaft 311 together to rotate.
As shown in Figure 2, according to one embodiment of present invention, the end face of a side of resetting shaft 312 offsets with the relative end face of driving shaft 311.Between resetting shaft 312 and driving shaft 311, have frictional resistance, the size of its moment is to be greater than driving shaft 311 to drive the needed torque of 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, makes the control law of air door 20 simple, good stability.
When applying the pulse signal of forward to stepper motor 30, air door 20 is opened and need to be turned 90 °, and the angle φ that at this moment stepper motor 30 rotates according to every step, rotates corresponding step number n.When air door is closed, need a pulse to air door n+1, a unnecessary pulse is closed closely for the reset of air door 20.For example, when air door 20 is opened the step number that needs stepper motor 30 to rotate and is 20, so, when air door is closed, need to give 20 21 pulse signals of air door, 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 and drives the needed torque of door-plate.At air door 20, do not have in resistant situation, air door 20 will rotate under the drive at driving shaft 311; When air door 20 receives that wind passage mouth stops, between driving shaft 311 and resetting shaft 312, will relatively rotate, 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.
