The embodiment of the utility model provides a self-guide structure of a push rod of an automatic door opener of a household appliance, which is shown by combining a figure 1, a figure 2, a figure 3 and a figure 4 and comprises the following components:

a push plate 20 having a through groove 21 formed thereon to form an installation space of the push rod 10;

a spring 30 having one end connected to the push rod 10 and the other end connected to the push plate 20;

a guide plate 22, which is obliquely arranged in the through groove 21 towards two sides, for guiding the moving direction of the push rod 10;

in the process that the push plate 20 is driven by external force to move towards the household appliance door body, the spring 30 deforms; when the spring 30 is released, the push rod 10 keeps moving linearly under the restriction of the guide plate 22 to correct the position deviation of the push rod 10 caused by the pulling force of the spring 30.

The utility model has the function of guiding the stroke track of the push rod 10 moving towards the direction of the household appliance door body in the through groove 21 by arranging the guide plate 22 in the through groove 21 of the push plate 20. Because the push rod 10 is connected with the push plate 20 through the spring 30, there is a certain time difference in the motion between the push plate 20 and the push rod 10, the position of the push rod 10 is deviated by the spring tension, this results in after the spring 30 is released, the push rod 10 can be displaced left and right in the through groove 21 when moving towards the direction of the household appliance door body, and the setting of the guide plate 22 plays a role in correcting the motion displacement of the push rod 10, so that the push rod 10 can ensure the linear motion when passing through the guide plate 22, further ensure that the thrust of the push rod 10 can act on the household appliance door body vertically, so that the door opening action is smoother, meanwhile, the friction force between the push rod 10 and the base 40 is reduced, and the occurrence of the damaged condition is avoided. Meanwhile, by arranging the spring 30, the effect of delaying door opening can be achieved, the rapid door opening action is avoided, so that a user feels obtrusive, and the use experience of the user is improved.

In an embodiment, as shown in fig. 4, an angle a between the guide plate 22 and the moving direction of the push rod 10 is set to 10 ° -20 °, wherein the guide plate 22 with the angle a smaller than 10 ° is liable to cause the push rod 10 to strike the guide plate 22 during the moving process, and the opening angle of the guide plate 22 with the angle a larger than 20 ° is liable to affect the guiding effect of the guide plate 22 on the push rod 10. Therefore, the angle α of 10 ° to 20 ° enables the guide plate 22 to guide the push rod 10 more efficiently, so that the push rod 10 moves more stably in the through groove 21.

In an embodiment, as shown in fig. 1, 2, 3 and 4, the guide plate 22 is disposed at an end of the through groove 21 close to the door body to ensure that the movement track of the push rod 10 during pushing out can be accurately guided, so that the pushing force of the push rod 10 can vertically act on the household appliance door body.

In one embodiment, as shown in fig. 4, the connection between the guide plate 22 and the through slot 21 is transited by an arc to reduce the friction between the push rod 10 and the guide plate 22. Specifically, the guide plate 22 includes a first guide plate 221 and a second guide plate 222, the first guide plate 221 is fixedly connected to the through slot 21 through a cylindrical connecting member 223, and a circular arc chamfer 224 is provided at a joint of the second guide plate 222 and the through slot 21 to reduce a friction force between the push rod 10 and the guide plate 22. When the push rod 10 passes through the guide plate 22, the connection part of the guide plate 22 and the through groove 21 is in contact with the side wall of the push rod 10, and a good guiding transition effect can be achieved on the push rod 10 in a mode that the cylindrical connecting piece 223 and the arc chamfer 224 are respectively arranged at the connection part, and on the other hand, the friction force between the push rod 10 and the guide plate 22 is reduced, so that the push rod 10 is prevented from being damaged due to the impact effect of edges and corners.

In one embodiment, as shown in fig. 4, the guide plate 22 is integrally formed with the through slot 21, and specifically, the first guide plate 221 is fixedly connected with the through slot bottom 212 by a cylindrical connecting member 223; the second guide plate 222 is disposed on the through-slot sidewall 211, i.e., the second guide plate 222 is integrated with the through-slot sidewall 211. Through the mode of deflector 22 integrated into one piece in logical groove 21, can guarantee the fastness of both junctions, the certain angle that keeps that first deflector 221 and second deflector 222 homoenergetic are stable, and in certain extent, deflector 22 can avoid producing the condition of warping under the impact of external force.

In one embodiment, the side of the guide plate 22 facing the channel of the push rod 10 is provided with an elastic buffer plate for buffering the impact force between the push rod 10 and the guide plate 22 to prevent the push rod 10 from being damaged.

In yet another embodiment, the surfaces of the guide plates 22 are lubricated to enable the push rod 10 to better engage between the guide plates 22, reducing the friction between the push rod 10 and the guide plates 22.

In one embodiment, as shown in fig. 3 and 5, the bottom 212 of the through groove is further provided with a sliding groove 23, and the push rod 10 is mounted on the sliding groove 23. Specifically, the lower surface 11 of the push rod is abutted against the upper surface 231 of the sliding slot, that is, the sliding slot 23 jacks up the push rod 10, so as to reduce the contact surface between the push rod 10 and the through slot 21 and reduce the friction force, so that the pushing action of the push rod 10 from the through slot 21 is smoother.

On the other hand, an embodiment of the present invention further provides an automatic door opening device, as shown in fig. 1, including: a base 40 for mounting the movable push plate 20; an external drive member 50 for providing a driving force to the push plate 20; and the self-guide structure of the push rod of the automatic door opener for the household appliances according to the technical scheme.

In an embodiment, the push plate 20 is symmetrically provided with two through groove positions about a central line, so as to drive two door opening push rods simultaneously, and better adapt to a large household appliance with double doors.

While embodiments of the utility model have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the utility model pertains, and further modifications may readily be made by those skilled in the art, it being understood that the utility model is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
