As shown in fig. 1 to 4, the present embodiment provides an automatic door opener, which can be used in a household appliance (e.g., a dishwasher) with an automatic door opening requirement, and is disposed on a door frame 100, and includes a top door mechanism and a balance mechanism 1. The top door mechanism is used for pushing the door body 200 open, so that the door body 200 rotates relative to the door frame 100 under the action of gravity to open. The structure of the top door mechanism is the prior art, and the top door mechanism can automatically lift the door body 200, so that the structure is not described again.
When dish washer operation drying program, the top door mechanism backs up the door body 200 and opens, door body 200 rotates and opens relative door frame 100 under self action of gravity, through the gravity of the balanced door body 200 of balance mechanism 1, make the door body 200 open to predetermineeing the angle, particularly, door body 200 drives elastic component 14 elastic deformation through first connecting piece 12 and second connecting piece 13, elastic component 14 produces sufficient elastic force and balances with door body 200's gravity mutually, and then make the angle that door body 200 opened invariable, need not to dispose the invariable angle of opening of special motor drive door body 200, the consumption of dish washer has been reduced, and this angle is enough big, the inside air flow speed of dish washer has been accelerated, steam discharge efficiency has been improved, drying effect has been promoted.
The preset angle is 8 to 10 degrees, and preferably, the preset angle is 9 degrees. When the door 200 is opened to form an included angle of 9 degrees with the door frame 100, the drying effect can be achieved to the maximum extent, and meanwhile, too large indoor space cannot be occupied.
In order to keep the two sides of the door body 200 stressed evenly, two balancing mechanisms 1 may be provided, and the two balancing mechanisms 1 are respectively disposed on the two sides of the door frame 100. Meanwhile, the symmetrical structure is adopted, so that the overall attractiveness of the dishwasher is enhanced. In order to facilitate the installation of the balance mechanisms 1, the door body 200 may be provided with a connecting rod 201, and the first connecting members 12 of the two balance mechanisms 1 are respectively rotatably connected to two ends of the connecting rod 201. In this embodiment, two ends of the connecting rod 201 are respectively provided with one mounting seat 202, the bottom of the mounting seat 202 is rotatably connected with the mounting plate 11, the mounting seat 202 rotates along with the door body 200, and the connecting rod 201 is erected between the two mounting seats 202.
To facilitate the mounting of the elastic element 14, the balancing mechanism 1 may further comprise a third connecting element 15, the elastic element 14 being connected to the second connecting element 13 via the third connecting element 15.

Preferably, one end of the third connecting member 15 is rotatably connected to the elastic member 14, and the other end of the third connecting member 15 is rotatably connected to the second connecting member 13. When the door body 200 drives the second connecting piece 13 to rotate around the joint of the second connecting piece and the mounting plate 11 through the first connecting piece 12, the second connecting piece 13 pulls the elastic piece 14 to generate elastic deformation through the third connecting piece 15, and the two ends of the third connecting piece 15 are connected in a rotating mode, so that the elastic piece 14 is kept vertical conveniently, the direction of the elastic deformation is along the axial direction of the elastic piece 14, the elastic piece 14 is prevented from being damaged, and the service life of the elastic piece 14 is prolonged.
The mounting plate 11 may be provided with a first limiting member, and when the door 200 is opened to a predetermined angle, the first connecting member 12 abuts against the first limiting member. The first limiting member may be a protrusion-shaped structure disposed on the mounting plate 11, and can be attached to the first connecting member 12 to generate a friction force. The mounting plate 11 may further be provided with a second limiting member, and when the door body 200 is closed, the second connecting member 13 abuts against the second limiting member. The second limiting member may be a hook-shaped structure disposed on the mounting plate 11, and can be attached to the second connecting member 13 to limit the second connecting member 13.
In this embodiment, the elastic member 14 may be a tension spring, and when the tension spring is pulled by the third connecting member 15, the tension spring elastically deforms to provide enough elastic force to balance the gravity of the door body 200, so that the door body 200 is kept open by a preset angle. In other embodiments, the elastic member 14 may also be a gas spring with higher cost and better performance, so as to enhance the user experience.
The automatic door opener provided by the embodiment has the following working process: when the dish washer runs a drying program, the door body 200 is pushed open by the door pushing mechanism, the door body 200 rotates relative to the door frame 100 under the action of self gravity and is opened, the mounting seat 202 rotates along with the door body 200, the mounting seat 202 generates acting force on the connecting rod 201, the connecting rod 201 simultaneously pulls the first connecting pieces 12 of the two balance mechanisms 1, the first connecting pieces 12 drive the second connecting pieces 13 to rotate around the joints of the second connecting pieces and the mounting plate 11, the second connecting pieces 13 drive the elastic pieces 14 to elastically deform through the third connecting pieces 15, the elastic pieces 14 generate enough elastic acting force to balance with the gravity of the door body 200, and further the angle at which the door body 200 is opened is constant, so that the steam inside the dish washer is conveniently discharged.
The automatic door opener that this embodiment provided need not to dispose the invariable angle of opening of special motor drive door body 200, has reduced the consumption of dish washer, and this angle is enough big for the inside air flow speed of dish washer, improved steam exhaust efficiency, promoted drying effect.
The embodiment also provides a dish washing machine, which comprises the automatic door opening device, and the dish washing machine is low in power consumption, good in drying effect and high in steam discharging efficiency.
