Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of MOD.
Referring to figs. 1 through Fig. 3, in one embodiment, this MOD comprises air door door-plate 10 and gear-box 20, this gear-box 20 comprises driven gear 21, collision piece 23 and stop part 22, wherein, driven gear 21 is connected with air door door-plate 10 and for driving air door door-plate 10 to rotate, collision piece 23 is located on driven gear 21, and this stop part 22 is for this collision piece 23 of backstop when air door door-plate 10 cuts out completely; This MOD also comprises master control borad 50 and pressure sensor 60, one end for backstop collision piece 23 of stop part 22 is located at by this pressure sensor 60, and be connected with master control borad 50 by wire, when stop part 22 backstop collision piece 23, collision piece 23 this pressure sensor 60 of conflicting sends the signal of telecommunication to trigger this pressure sensor 60 to master control borad 50.
In the present embodiment, when air door door-plate 10 cuts out completely, this this collision piece 23 of stop part 22 backstop, when closing completely to prevent air door door-plate 10, driven gear 21 still rotates; And the upper end of stop part 22 is located at by pressure sensor 60, to make to conflict during stop part 22 this collision piece 23 of backstop this pressure sensor 60, namely when this pressure sensor 60 is subject to the conflict pressure of collision piece 23, represent that air door door-plate 10 cuts out completely, now this pressure sensor 60 sends the signal of telecommunication to master control borad 50, so when master control borad 50 receives the signal of telecommunication that pressure sensor 60 sends over, the wind cooling refrigerator with this MOD can judge whether this air door door-plate 10 closes completely in closing process.In the present embodiment, pressure sensor 60 can be with the fixed form of stop part 22 but be not limited to rivet.
In the present embodiment, this pressure sensor 60 can be but be not limited to semiconductor pressure resistance type pressure sensor or capacitance-type pressure sensor, wherein, deposition tube damping force snesor forms semiconductor strain pressure at sheet surface, make thin metal plate by external force (pressure) and produce Piezoelectric Impedance effect, thus making the change of impedance convert the signal of telecommunication to; Capacitance-type pressure sensor is that the movable extremely relative of the fixed pole of glass and silicon is formed electric capacity, can convert the signal of telecommunication to by passing through the change that external force (pressure) makes its movable pole be out of shape the static capacity produced.
Whether the MOD that the present embodiment provides detects air door door-plate 10 by the pressure sensor 60 of the one end for backstop collision piece 23 being located at stop part 22 and closes completely, and send the signal of telecommunication when this pressure sensor 60 is subject to the conflict pressure of collision piece 23 to master control borad 50, thus whether this air door door-plate 10 closes completely in closing process to make the wind cooling refrigerator with this MOD to judge, so that this wind cooling refrigerator reminding user when air door door-plate 10 needs to cut out and do not cut out completely carries out respective handling, thus avoid refrigerating chamber cross cold even freeze etc. severe phenomenon, reduce the generation of this kind of wind cooling refrigerator quality problems, improve the intelligent of this kind of wind cooling refrigerator.
Further, in the present embodiment, this MOD also comprises drive unit 70, this drive unit 70 to be arranged in gear-box 20 and to be connected with master control borad 50 by wire, this drive unit 70 rotates for the driven gear 21 of the control signal driving gearbox 20 according to master control borad 50, thus drive air door door-plate 10 to open or close, this drive unit 70 also stops operating for the driven gear 21 of the control signal driving gearbox 20 according to master control borad 50, stops at enable possition or closed position to make air door door-plate 10.In the present embodiment, when master control borad 50 control this drive unit 70 have rotated default amount of spin and do not receive the signal of telecommunication that pressure sensor 60 sends over time, this master control borad 50 can continue to control this drive unit 70 and rotate, namely, when when this drive unit 70 have rotated default amount of spin, air door door-plate 10 does not cut out completely, drive unit 70 can be rotated further and drive air door door-plate 10 to cut out; Until this master control borad 50 receives the signal of telecommunication that pressure sensor 60 sends over, this master control borad 50 just controls this drive unit 70 power down and stops operating, so, can avoid MOD in the process of closing, be subject to the air door door-plate 10 that external interference causes and not close phenomenon completely.In the present embodiment, this drive unit 70 can be but be not limited to stepper motor, and presets the default stepping-in amount that amount of spin is this stepper motor.
Further, in the present embodiment, this MOD also comprises air door doorframe 30 and is located at the heater 40 between air door door-plate 10 and air door doorframe 30, and this heater 40 is connected with master control borad 50 by wire, and for heating according to the control signal of master control borad 50.
Concrete, in the present embodiment, this heater 40 comprises heater strip, air door doorframe 30 is provided with storage tank 31, heater strip is placed in this storage tank 31 and fixes with air door doorframe 30, when master control borad 50 control this drive unit 70 rotate preset amount of spin and do not receive the signal of telecommunication that pressure sensor 60 sends over time, master control borad 50 controls this heater 40 and heats, now occur that drive unit 70 rotates amount of spin and the situation that air door door-plate 10 does not cut out completely preset, this situation is caused owing to air door door-plate 10 existing the stop of little ice pellets most probably, the heater 40 be fixed in air door doorframe 30 carries out heating and can melt little ice pellets and cut out further to make air door door-plate 10, thus get rid of because little ice pellets stops that severe phenomenon that the air door door-plate 10 caused can not cut out completely (for the purpose of safety, the laser heating time of heater 40 is unsuitable long).
Further, in the present embodiment, this MOD also comprises warning device 80, and this warning device 80 is located on master control borad 50, and for sending alarm signal according to the control signal of master control borad 50.Concrete, in the present embodiment, when master control borad 50 accessory drive 70 rotate preset amount of spin and do not receive the signal of telecommunication that pressure sensor 60 sends over time, master control borad 50 controls this warning device 80 and sends alarm signal, namely when when this drive unit 70 have rotated default amount of spin, air door door-plate 10 does not cut out completely, warning device 80 can send alarm signal, to notify that the phenomenon that air door door-plate 10 is interfered in the process of cutting out has appearred in the refrigerator that user has this MOD, thus remind this user to pay close attention to the situation of this refrigerator, with the article avoiding refrigerating chamber to cross cold and freezing user, reduce the loss of user when quality problems appear in refrigerator.
In the present embodiment, master control borad 50 draws 8 wires altogether, wherein 2 wires be used for Bonding pressure sensor 60,4 wires be used for connection control drive unit 70 with realize air door door-plate 10 and open or close and 2 wires for the heating of connection control heater strip or stop heating.
The present invention also provides a kind of refrigerator.
In one embodiment, this refrigerator comprises the MOD in previous embodiment.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
