As shown in fig. 1 and 2, the household door opening appliance according to an embodiment of the present invention includes a box 500 and a door opening and closing system, wherein one side of the box 500 is pivoted with a door 300 and forms a single-door box, a pivot (not shown in the drawing) is disposed between the door 300 and the box 500, the door opening and closing system includes a door opening and closing device 100 and a door pushing device 200, the door opening and closing device 100 and the door pushing device 200 are both mounted on a top surface of the box 500, a top edge 310 is disposed at a top of the door 300, a sealing magnetic stripe (not shown in the drawing) is disposed on an inner side surface of the door 300, and the box 500 is also provided with a sealing magnetic stripe matched with the door 300. It is understood that the door opening and closing device 100 and the top door device 200 may also be installed on the bottom surface of the cabinet 500, without being limited thereto; and two sealing magnetic stripes are not both magnetic, one sealing magnetic stripe can be magnetic, and the other sealing magnetic stripe is attracted.
Specifically, a convex mounting plate 510 is arranged on the top surface of the box 500, the door opening and closing device 100 includes a power source 110, a power gear 120 and a door rotating mechanism 130, the power source 110 is preferably a speed reduction motor, and the power source 110 is mounted below the mounting plate 510 and drives the power gear 120; the present invention is not limited to the arrangement of the mounting plate 510, and if the present invention is not provided with the mounting plate 510, the power source 110 is directly mounted on the top surface of the box 500, and even if it occupies additional space on the top surface of the box 500, it still does not affect its normal use. The door body rotating mechanism 130 comprises an input end 131 and an output end 132, the input end 131 is a coaxial double-tooth gear, the output end 132 is a door gear located on a pivot of the door body 300, when the door gear rotates, the door body 300 also rotates, and vice versa; the input end 131 and the output end 132 are in transmission connection through a belt transmission structure or a gear transmission structure, and the power gear 120 is engaged with the input end 131, so that the power source 110 can drive the door 300 to rotate to open or close.
The top door device 200 comprises a top wheel 210, a top rod 220 and a guide block 230, wherein one end of the top rod 220 is provided with a top door piece 221, the top door piece 221 is close to the top edge 310 of the door body 300, the top door piece 221 is abutted against the top edge 310 of the door body 300 in the process of door lifting, namely, the top door piece 221 is mainly used for lifting the door body 300; in order to avoid the position deviation of the top bar 220 in the door pushing process, the number of the guide blocks 230 is two, the two guide blocks 230 are fixedly connected to the top surface of the box body 500, the two guide blocks 230 are both provided with guide holes, and the top bar 220 sequentially passes through the two guide holes, so that the top bar 220 has guidance. The top wheel 210 is coaxially connected with the power gear 120, that is, the top wheel 210 rotates along with the power gear 120, the shape of the top wheel 210 can be shown in fig. 7 and 8, and the top wheel 210 is a cam 211 or an eccentric 212; the rotation path of the top wheel 210 intersects with the top rod 220, so that the top wheel 210 can push the top rod 220 outwards, and the top door piece 221 on the top rod 220 can push the door body 300 open every time the top wheel 210 pushes the top rod 220 outwards. It is understood that the rotation path of the top wheel 210 specifically refers to the rotation path of the protrusion 201 on the cam 211 if the top wheel 210 is the cam 211, and specifically refers to the maximum rotation path of the eccentric 212 if the top wheel 210 is the eccentric 212. Compared with the eccentric wheel 212, the cam 211 can obviously reduce the moving frequency of the ejector rod 220, so the ejector wheel 210 in the invention is preferably the cam 211, the cam 211 is provided with a circular arc convex outer edge 2111, two ends of the convex outer edge 2111 are respectively in transition connection with the outer edge 2112 of the circular wheel through a gradual transition curve 2113, the gradual transition curve 2113 is preferably a curve meeting the sine acceleration motion law of the ejector rod 220, and the arrangement can ensure that the movement of the ejector rod 220 is more stable without rigid impact or flexible impact; the height of the cam 211 above the protrusion 201 should be controlled within a proper range, so that when the top door piece 221 jacks the door 300, the door 300 is not opened greatly, and the distance between the door 300 and the box 500 is about 3mm-8 mm; in order to open and close the door 300, the rotation path of the power gear 120 is a circular arc instead of a full circle, and the same applies to the rotation path of the top wheel 210. Because the door opening and closing device 100 and the door top device 200 are linked, the door opening and closing system can open the door body 300 sequentially through the door top device 200 and the door opening and closing device 100 when opening the door, but in order to avoid the abrasion of the gear caused by the passive engagement of the power gear 120 and the input end 131 when opening the door, the power gear 120 is preferably an intermittent gear which is provided with one or more than one tooth part 121, the intermittent gear is not engaged with the input end 131 when the door body 300 is opened, the intermittent gear is engaged with the input end 131 after the door body 300 is opened, that is, the action of the cam 211 pushing the push rod 220 is not synchronous with the action of the intermittent gear driving the input end 131.
In some embodiments of the present invention, the door lifting device 200 further includes a return mechanism 240, the return mechanism 240 includes a spring 241 and a limit plate 242, the limit plate 242 is fixedly connected to the lift rod 220, the limit plate 242 is specifically located between the cam 211 and the guide block 230, the spring 241 is sleeved on the lift rod 220, two ends of the spring 241 are respectively abutted against the limit plate 242 and the guide block 230, at this time, the spring 241 has a pre-pressing elastic force, so that the end of the lift rod 220 provided with the limit plate 242 is kept abutted against the cam 211. When the cam 211 pushes the top bar 220 outwards, the spring 241 is further compressed, and after the protrusion 201 of the cam 211 rotates over the top bar 220, the top bar 220 starts to return and always keeps abutting with the cam 211 under the action of the spring 241. In addition, in order to reduce the friction between the push rod 220 and the cam 211, a freely rotatable driven wheel 222 is provided at the end of the push rod 220 close to the cam 211, the driven wheel 222 is in contact with the cam 211, and each time the cam 211 rotates, the driven wheel 222 rotates along with the cam to reduce the friction between the cam 211 and the driven wheel.
In some embodiments of the present invention, the return mechanism 240 may further include a sliding slot (not shown in the drawings) disposed on the circumferential surface of the cam 211, and the driven wheel 222, where the cam 211 is a grooved cam, and the driven wheel 222 is connected in the sliding slot in a limited sliding manner, so that the push rod 220 can move along with the grooved cam.
For the single door case, the door opening and closing modes can be divided into a manual mode and an automatic mode, in the manual mode, since the power gear 120 is an intermittent gear, as long as the power source 110 does not drive the intermittent gear to rotate, the intermittent gear is not engaged with the input end 131, and thus a user can manually open or close the door 300. In addition, in the automatic mode, after the user presses the automatic opening button, the power source 110 will drive the intermittent gear and the cam 211 to rotate simultaneously, after the cam 211 starts to rotate, the top rod 220 will be pushed outwards by the cam 211 and the top door 221 thereof will be pushed to open the door 300, and then the intermittent gear will start to engage with the input end 131, so that the output end 132 can drive the door 300 to open; after the user pressed the self-closing button, power supply 110 drove the intermittent gear carries out the antiport, makes output 132 can drive the door body 300 closes, closes to a certain degree at door body 300 after, the intermittent gear with input 131 breaks away from the meshing, because at this moment door body 300 has certain inertia and the magnetic attraction that the stack has sealed magnetic stripe, therefore door body 300 can continue to close. It should be further noted that after the intermittent gear is disengaged from the input end 131, the push rod 220 still has an ejection state under the action of the cam 211, which is interfered with the motion path of the door 300 for closing, but because the door 300 is in an inertial closing state at this time, the door closing speed lags behind the return speed of the cam 211 driving the push rod 220, the door 300 is orderly staggered from the interference possibly existing with the push rod 220 in the closing process, and because the amplitude of the push rod 221 capable of ejecting the door 300 is small, about 3mm to 8mm of gap, in which the sealing magnetic stripe can close the door 300 by magnetic attraction.
As shown in fig. 3 to 6, according to another embodiment of the household appliance with a door opening function of the present invention, two sides of the box 500 are respectively pivoted with a door 300 to form a double-door box, a pivot is provided between each door 300 and the box 500, and the double-door box is different from the single-door box in that: the number of the door rotating mechanisms 130 of the double-door box body is two, the two door rotating mechanisms 130 are respectively arranged corresponding to the two doors 300, that is, the two input ends 131 are respectively arranged at two sides of the power gear 120, the two output ends 132 are respectively arranged on the two pivots, the power gear 120 is respectively in transmission connection with the two input ends 131, but in order to enable the two doors 300 to be opened or closed simultaneously, a reversing gear 400 is arranged between one of the input ends 131 and the power gear 120, and the other input end 131 is meshed with the power gear 120; when the power gear 120 is preferably an intermittent gear with two teeth 121, the top door 221 of the top rod 220 acts on the top edges 310 of the two door bodies 300 respectively.
In some embodiments created by the present invention, only the two input ends 131 need to be replaced with coaxial double-toothed gears of different dimensions or the two output ends 132 need to be replaced with door gears of different dimensions, and the opening amplitudes of the two door bodies 300 can be controlled separately in this embodiment, so as to meet different requirements of users.
For the above-mentioned double-door box, the door opening and closing modes can be divided into a manual mode and an automatic mode, in the manual mode, since the power gear 120 is an intermittent gear, as long as the power source 110 does not drive the intermittent gear to rotate, the intermittent gear will not be transmitted with the input end 131, so that the user can manually open or close the two door bodies 300. In addition, in the automatic mode, after the user presses the automatic opening button, the power source 110 will simultaneously drive the intermittent gear and the cam 211 to rotate, after the cam 211 starts to rotate, the top rod 220 will be pushed by the cam 211 and the top door 221 thereof will simultaneously open the two door bodies 300, and then the intermittent gear starts to drive the two input ends 131 to simultaneously rotate, so that the two output ends 132 can respectively drive the corresponding door bodies 300 to open; after the user pressed the self-closing button, power supply 110 drove the intermittent gear carries out antiport for two output 132 can drive the door body 300 that corresponds respectively and close, closes to a certain extent at two door bodies 300 after, the intermittent gear simultaneously with two input 131 breaks away from the meshing, because two this moment door bodies 300 have certain inertia and the magnetic attraction that the stack has sealed magnetic stripe, consequently two door bodies 300 can continue to close.
Based on the structure, compared with the prior art, the door opening and closing system can automatically open or close one or two door bodies 300 only by adopting one power source, so that the manufacturing cost of the door opening household appliance is effectively saved, and the door opening and closing system is more competitive in the market; and because the door opening and closing device 100 and the top door device 200 are linked, the control of the door opening household appliance is simpler and the automatic door opening action is smoother.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
