It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of embodiments according to the present application, however, embodiments according to the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited by the specific embodiments disclosed below.

An electromagnetic door opening device and a refrigeration appliance according to some embodiments of the present application are described below with reference to fig. 1 to 13.

In one embodiment of the present application, an electromagnetic door opening device 1 is provided.

As shown in fig. 1 and 2, the electromagnetic door opener 1 includes a base 11, an electromagnetic assembly 12 and a driving assembly 13, and may be mounted to a refrigeration appliance 2 having a plurality of doors 22.

The base 11 is used as a mounting base of the electromagnetic door opener 1 and can be connected with the refrigeration equipment 2; the electromagnetic assembly 12 and the driving assembly 13 are both mounted on the base 11 to realize the assembly of the electromagnetic door opening device 1 on the refrigeration equipment 2.

The electromagnetic assembly 12 is rotatably connected with the base 11 and can rotate relative to the base 11. The driving assembly 13 is in transmission connection with the electromagnetic assembly 12 to output power to the electromagnetic assembly 12, so that the electromagnetic assembly 12 rotates relative to the base 11.

The electromagnetic assembly 12 may utilize electromagnetic action to extend the push rod 122 outwardly with respect to the assembly as a whole; when the electromagnetic door opening device 1 is mounted on the refrigeration apparatus 2 at a position corresponding to the door 22, the door 22 can be pushed to open by the extending operation of the push rod 122. It can be understood that, for example, the door 22 of a refrigerator or the like needs to overcome a large resistance at the moment of opening due to the magnetic force and the negative pressure inside the refrigerator, and the solution of the embodiment can realize an automatic door opening operation, is convenient for users to use, is particularly suitable for old people and children, and can effectively improve the convenience of the refrigeration device 2 especially in the case of holding articles in the hands of the users.

When the refrigeration device 2 is provided with a plurality of doors 22, the electromagnetic assembly 12 can rotate relative to the base 11 under the driving of the driving assembly 13 to change the orientation of the push rod 122, so that the push rod 122 faces to different doors 22, and then different doors 22 are pushed to open.

It should be noted that the refrigeration device 2 may be a refrigerator, freezer or other device capable of refrigerating.

The electromagnetic door opener 1 in this embodiment can open different doors 22 on the refrigeration equipment 2 through one set of device when being assembled on the refrigeration equipment 2, so that the refrigeration equipment 2 does not need to be equipped with a door opener for each door 22 alone, thereby simplifying the overall structure, reducing the total number of components, facilitating installation and maintenance operation, and enabling a matched control circuit to be relatively simple, and being beneficial to reducing the cost.

In some embodiments of the present application, as shown in fig. 1-3, the electromagnetic assembly 12 includes an electromagnetic body 121 and a push rod 122. Specifically, a part of the push rod 122 extends into the electromagnetic body 121, and the push rod 122 and the electromagnetic body 121 form a sliding connection therebetween; another portion of the push rod 122 is located outside the electromagnetic body 121 and is used for contacting the door 22 of the refrigeration device 2.

When the electromagnetic body 121 works, an electromagnetic field is generated inside, and the push rod 122 can be driven to extend outwards by the action of the magnetic field to push the door 22 open, so that the door opening operation is realized.

Compared with a motor driving mode, the electromagnetic driving mode of the push rod 122 in the embodiment has the advantages of simple structure, fast response speed, high reliability and the like, and is convenient to use.

In some embodiments of the present application, as shown in fig. 3 and 4, the electromagnetic body 121 specifically includes a housing 1211 and an electromagnetic generating member. An electromagnetic generating element, specifically a solenoid device 1214, disposed in a cavity within the housing 1211 and fixedly connected to the housing 1211; housing 1211 can provide isolation and protection for solenoid assembly 1214. A through hole is formed in the casing 1211 at a position corresponding to the push rod 122, and one end of the push rod 122 extends into the casing 1211 and is slidably connected to the solenoid device 1214.

When the solenoid device 1214 is operated, an electromagnetic field is generated inside, and the push rod 122 is located in the electromagnetic field formed by the solenoid device 1214 and extends outwards under the driving of the action of the magnetic field, so that the door opening operation is realized.

In some embodiments of the present application, as shown in fig. 3 and 4, a spring 1215 is further provided within the housing 1211 for resetting the push rod 122. Specifically, the push rod 122 passes through the solenoid device 1214 and extends from the other end, the spring 1215 is sleeved outside the push rod 122, and two ends of the spring 1215 respectively abut against the tail end of the push rod 122 and the solenoid device 1214. During the process that the push rod 122 extends outwards, the push rod 122 compresses the spring 1215 to generate elastic deformation, and the spring 1215 has a movement tendency of restoring to the original state; after the push rod 122 completes the door opening operation, the magnetic field of the solenoid 1214 is removed, and at this time, the push rod 122 is retracted inward by the elastic force of the spring 1215, so that the reset is realized.

It should be noted that the position of the spring 1215 is not limited to the position in this embodiment, for example, the spring 1215 may also be sleeved on the push rod 122 at the position of the front end of the solenoid device 1214, and the elastic reset function may also be achieved, which is not described herein again. In addition, the spring 1215 may be replaced by other elastic members, which can also achieve the restoring action.

In some embodiments of the present application, as shown in fig. 3 and 4, a torsion spring 1216 is further disposed in the casing 1211 for buffering and limiting the push rod 122. Specifically, the torsion spring 1216 is disposed in the casing 1211 at a position away from the extending end of the push rod 122, an upright 1217 is correspondingly disposed in the casing 1211, the torsion spring 1216 is sleeved on the upright 1217, one end of the torsion spring 1216 is connected to the tail of the push rod 122, and the other end is connected to the casing 1211.

During the process of retracting the push rod 122 inwards, due to inertia, the push rod 122 may exceed the initial position, and at this time, the push rod 122 drives the torsion spring 1216 to generate torsional deformation, and the elastic force of the torsion spring 1216 can play a role in buffering and limiting the push rod 122, and can prevent the push rod 122 from contacting or colliding with the casing 1211.

It should be noted that the torsion spring 1216 in this embodiment may be replaced by other elastic components, such as an elastic cushion, which can also achieve the buffering and limiting functions.

In some embodiments of the present application, as shown in fig. 3 and 4, the casing 1211 specifically includes a lower housing 1212 and an upper housing 1213, which are detachably coupled to each other. As shown in fig. 5 and 6, the base 11 is provided with a convex column 111, and correspondingly, the bottom surface of the lower housing 1212 is provided with a through hole and sleeved on the convex column 111 of the base 11, so as to realize the rotational connection between the lower housing 1212 and the base 11.

As shown in fig. 3 and 4, the upper case 1213 is closed over the lower case 1212 and forms an accommodation chamber together with the lower case 1212 to accommodate the solenoid device 1214. The solenoid assembly 1214 is fixedly connected to the lower housing 1212, and the upper housing 1213 can be removed to facilitate maintenance when maintenance is required inside the electromagnetic housing 121.

In some embodiments of the present application, as shown in fig. 7, the drive assembly 13 includes a drive mechanism 131 and a transmission mechanism 132. The driving mechanism 131 is used for outputting power; two ends of the transmission mechanism 132 are respectively connected to the output end of the driving mechanism 131 and the electromagnetic body 121, so that when the driving mechanism 131 works, the transmission mechanism 132 transmits power to the electromagnetic body 121 to drive the electromagnetic body 121 to rotate relative to the base 11, and further the push rod 122 of the electromagnetic assembly 12 faces different doors 22 to push the corresponding doors 22 to open.

In some embodiments of the present application, as shown in fig. 7 and 8, the transmission mechanism 132 specifically includes a pendulum 1321 and a connecting rod 1322. The swing rod 1321 is connected with the output end of the driving mechanism 131, and the connecting rod 1322 is rotatably connected with the electromagnetic machine body 121. A lug 1323 is arranged on the swing rod 1321, and the lug 1323 is positioned at one end, far away from the driving mechanism 131, of the swing rod 1321; correspondingly, the connecting rod 1322 is provided with a sliding slot 1324, the sliding slot 1324 extends along the length direction of the connecting rod 1322, and the projection 1323 extends into the sliding slot 1324 and forms a fit with the sliding slot 1324, so that the connection between the swing rod 1321 and the connecting rod 1322 is realized.

Specifically, the sliding slot 1324 may have a rectangular structure, and the protrusion 1323 may rotate relative to the connecting rod 1322 and slide relative to the sliding slot 1324, so as to change the connection form between the swing link 1321 and the connecting rod 1322.

In the working process, the swing rod 1321 and the connecting rod 1322 rotate under the driving of the driving mechanism 131, and further the electromagnetic machine body 121 is driven to rotate. In the rotating process, the swing rod 1321 and the connecting rod 1322 can rotate and slide relatively without mutual interference, so that the clamping phenomenon can be prevented.

It should be noted that the pendulum 1321 and the connecting rod 1322 are not limited to the connection manner in the embodiment, for example, a sliding slot 1324 may be provided on the pendulum 1321, and a projection 1323 may be provided on the connecting rod 1322, so that the pendulum 1321 and the connecting rod 1322 can be rotatably and slidably engaged with each other.

In some embodiments of the present application, in one implementation of the present embodiment, as shown in fig. 7 and 8, the driving mechanism 131 is embodied as a rotary electromagnet 1311 for outputting torque by electromagnetic action. The rotary electromagnet 1311 is fixedly connected to the base 11, and an output rotating shaft of the rotary electromagnet 1311 is fixedly connected to the swing rod 1321, so that when the rotary electromagnet is in operation, the output rotating shaft drives the swing rod 1321 to rotate together, and further the connecting rod 1322 drives the electromagnet body 121 to rotate relative to the base 11, thereby achieving the direction adjustment of the push rod 122. The connection relationship between the swing link 1321 and the connecting rod 1322 enables the swing link 1321 and the connecting rod 1322 to rotate relatively, so as to prevent the jamming phenomenon caused by mutual interference in the rotating process.

In another implementation of this embodiment, as shown in fig. 9, 10 and 11, the driving mechanism 131 is embodied as a linear electromagnet 1312 to electromagnetically move the output end linearly. The output end of the linear electromagnet 1312 is fixedly connected with one end of the swing rod 1321, and the other end of the swing rod 1321 is matched with the connecting rod 1322. When the linear electromagnet 1312 works, the swing rod 1321 is driven to perform linear motion by the linear electromagnet 1312, and then the electromagnet body 121 is driven to rotate relative to the base 11 by the connecting rod 1322, so that the direction adjustment of the push rod 122 is realized. The connection relationship between the swing link 1321 and the connecting rod 1322 enables the swing link 1321 and the connecting rod 1322 to rotate relatively, so as to prevent the jamming phenomenon caused by mutual interference in the rotating process.

It should be noted that the driving mechanism 131 is not limited to the implementation provided in this embodiment, and other devices capable of driving the electromagnetic body 121 to rotate may also be used, and are not described herein again.

In some embodiments of the present application, as shown in fig. 7 and fig. 9, a plurality of limit blocks 14 are further disposed on the base 11 for limiting the rotation of the electromagnetic body 121. Specifically, the limit blocks 14 are respectively located at two sides of the electromagnetic body 121, for example, as shown in fig. 7 and fig. 9, four limit blocks 14 are respectively arranged at two sides of the electromagnetic body 121, so that when the electromagnetic body 121 rotates, the limit blocks 14 block the electromagnetic body 121, and the rotation of the electromagnetic body 121 is limited within a suitable range, so as to reduce an invalid rotation stroke. When the electromagnetic door opener 1 is assembled on the refrigeration equipment 2, the push rod 122 is aligned with the door 22 conveniently, and positioning can be achieved.

The two limiting blocks 14 on the same side may be respectively disposed corresponding to the front portion and the rear portion of the electromagnetic machine body 121, so that two limiting blocks 14 located on diagonal positions in the four limiting blocks 14 form a group to limit one direction of the electromagnetic machine body 121.

For example, as shown in fig. 7, when the electromagnetic body 121 rotates counterclockwise, the front portion of the electromagnetic body 121 abuts against one of the limit blocks 14 on the left side, the rear portion abuts against one of the limit blocks 14 on the right side, and the two limit blocks 14 are located at diagonal positions, at this time, the push rod 122 faces one of the doors 22 of the refrigeration device 2; conversely, when the electromagnetic body 121 rotates clockwise, the front portion of the electromagnetic body 121 abuts against one of the limit blocks 14 on the right side, the rear portion abuts against one of the limit blocks 14 on the left side, the two limit blocks 14 are located at the other diagonal position, and at this time, the push rod 122 faces the other door 22 of the refrigeration apparatus 2.

Further, the limiting block 14 may be obliquely disposed so as to be adapted to the rotation angle of the electromagnetic machine body 121 when abutting against the electromagnetic machine body 121, so as to increase the contact area with the electromagnetic machine body 121.

A specific embodiment of the above described electromagnetic door opening device 1 is provided below:

as shown in fig. 1 and fig. 2, the electromagnetic door opener 1 may be mounted on the refrigeration equipment 2 at a position corresponding to the door 22, for example, when the refrigeration equipment 2 is a refrigerator, the electromagnetic door opener 1 may be disposed on the top of the box 21 of the refrigerator, and the push rod of the electromagnetic door opener is disposed corresponding to the two doors 22 of the refrigerator.

Specifically, as shown in fig. 1 to 4, when one of the doors 22 needs to be opened, the driving assembly 13 of the electromagnetic door opening device 1 starts to operate, the driving mechanism 131 outputs power to the electromagnetic assembly 12 through the transmission mechanism 132, and drives the electromagnetic assembly 12 to rotate relative to the base 11, so that the push rod 122 rotates to abut against the limit block 14, and at this time, the push rod 122 faces the door 22 needing to be opened; then, the electromagnetic body 121 of the electromagnetic assembly 12 starts to operate, the solenoid device 1214 inside generates an electromagnetic field, and drives the push rod 122 to extend outwards by electromagnetic action, so as to push the door 22 to rotate outwards, thereby realizing the door opening operation.

During the process of extending the push rod 122 outward, the spring 1215 sleeved on the push rod 122 is compressed; after the door opening operation is completed, the electromagnetic body 121 is in the operating state, the electromagnetic field of the solenoid device 1214 is removed, and the push rod 122 is retracted inward by the elastic force of the spring 1215 to realize the reset. Wherein the tail torsion spring 1216 connected to the push rod 122 can buffer and limit the push rod 122.

When the other door 22 needs to be opened, the driving mechanism 131 of the driving assembly 13 outputs reverse power, and drives the electromagnetic assembly 12 to rotate reversely relative to the base 11 through the transmission mechanism 132, so that the push rod 122 rotates to abut against the limit block 14 on the other side, and at this time, the push rod 122 faces the other door 22; then, the electromagnetic body 121 of the electromagnetic assembly 12 starts to operate, the solenoid device 1214 inside generates an electromagnetic field, and drives the push rod 122 to extend outwards by electromagnetic action, so as to push the door 22 to rotate outwards, thereby realizing the door opening operation.

The process of the spring 1215 for resetting the push rod 122 and the process of the torsion spring 1216 for buffering and limiting the push rod 122 are similar to the above description, and are not repeated herein.

The shape of the side of the stopper 23 facing the electromagnetic assembly 12 is adapted to the rotation track of the push rod 122, for example, an arc-shaped groove as shown in fig. 12 is provided on the stopper 23, so that when the push rod 122 rotates towards the other door 22 in a state that the push rod 122 has a certain extension amount, the rotation track of the push rod 122 can be adapted to the shape of the stopper 23 to prevent interference.

Furthermore, the stop 23 is further provided with a partial inclined surface structure, the inclined surface structure is connected with the arc-shaped groove, and at a position close to the other door 22, the inclined surface structure is inclined towards a direction far away from the electromagnetic assembly 12, so that the stop 23 forms a step-shaped groove block.
