Description

Automatic opening device for refrigerator

The invention relates to an automatic opening device, in particular to an automatic opening device for a refrigerator.

Food is the most important thing for the people, and everyone has to eat every day. Modern people usually use refrigerators to refrigerate and freeze food to keep food fresh. Therefore, almost every modern family has at least one refrigerator.

When we use the refrigerator, we often have inconveniences. For example, the door of the refrigerator is usually sealed in order to avoid improper opening. Therefore, we must apply a certain pulling force to the door to open the door. When holding food, or having hand injury, or hand weakness, etc., it is inconvenient to use the hand to open the door of the refrigerator. This situation is very troublesome for us.

Therefore, it is indeed necessary to design a simple action that can use the body to touch the switch so that the user can easily and conveniently open the refrigerator.

It is that the inventor of the present invention is based on many years of practical experience in product design and development, as well as active research and development thinking, and through countless actual tests and experiments, the invention has been produced.

The purpose of the present invention is to provide a refrigerator automatic opening device that can easily and conveniently open the refrigerator by simply touching the switch with the body.

In order to achieve the above-mentioned object, the present invention includes a refrigerator body and a door panel, wherein the refrigerator body has a groove beside the opening, and a supporting member is provided in the groove, and the supporting member has a number of coil posts. The number coil post is used to sleeve several connected coils. One end of the number coil post is provided with a metal body; one side of the door panel is pivotally connected to the refrigerator body in a movable shape to block the opening. The door panel has a The magnetic strip corresponds to and magnetically attracts the metal body. The door panel has a switch that is electrically connected to the power supply of the digital coil and the refrigerator body to control the power supply of the digital coil so that the digital coil generates a and The magnetic stripe repels each other, and the force is greater than the magnetic repulsion force of the magnetic attraction force between the magnetic stripe and the metal body.

The user can touch the switch at any part of the body to make the coil conductive, and the magnetic repulsive force generated by the coil can push the door open, forming an automatic door opening shape, allowing the user to hold food or If you have other problems with your hands, and it is not convenient to open the door of the refrigerator with your hands, you can easily and conveniently open the refrigerator by simply touching the switch with your body, thereby enhancing the practical functions of the refrigerator.

The following is only a detailed description with specific embodiments and drawings, so that your reviewer can have a better understanding and understanding of the functions and features of the present invention.

Please refer to FIG. 1, FIG. 2, and FIG. 3, the present invention includes a refrigerator body 10 and a door panel 20. The following will explain in detail:

The refrigerator body 10 has a groove 12 on the side of the opening 11, and a supporting member 30 is provided in the groove 12, and the supporting member 30 has a number coil post 31, and the number coil post 31 is used for sleeved connection For the coil 32, a metal body 40 is provided at one end of the coil column 31.

The door panel 20 has a switch 22 which is electrically connected to the power supply of the digital coil 32 and the refrigerator body 10 to control the power supply of the digital coil 32 so that the digital coil 32 generates a repulsion with the magnetic strip 21, And the force is greater than the magnetic repulsion force of the magnetic attraction force between the magnetic strip 21 and the metal body 40.

In one embodiment, the magnetic strip 21 is covered by a protective cover 23 to hide and protect the magnetic strip 21.

In one embodiment, a door elastic opening mechanism is provided at the movable pivot joint of the door panel 20, and the door elastic opening mechanism is attached to the refrigerator body 10 with a first shaft seat 50 and a second shaft on one side and at the bottom. Seat 60, the first shaft seat 50 has a first hole seat 51, one side of the first hole seat 51 is provided with a protruding plate 52, the second shaft seat 60 has a second hole seat 61, the second hole seat 61 An arc groove 62 is provided on the surface; the door panel 20 has a first shaft sleeve 71 and a second shaft sleeve 72 inside the door panel 20. The second shaft sleeve 72 is provided with a shape that can match and guide the arc groove 62 The arc-shaped portion 721 passes a rotating shaft 70 through the first sleeve 71 and the second sleeve 72, and the upper and lower ends of the rotating shaft 70 are respectively sleeved into the first hole seat 51 and the second hole seat 61, One side of the door panel 20 is pivotally connected to the refrigerator body 10 in a movable manner; a torsion spring 73 is arranged on the rotating shaft 70, one end of the torsion spring 73 abuts the protruding plate 52, and the other end of the torsion spring 73 abuts the door panel 20. The door panel 20 is used to generate an outward opening elastic force, but the elastic force is smaller than the magnetic attraction force between the magnetic strip 21 and the metal body 40. Accordingly, the door panel 20 will not affect the sealing of the refrigerator body 10.

In one embodiment, the groove 12, the supporting member 30, and the metal body 40 are formed in a shape of ㄈ.

The above is an introduction to the composition of the present invention, and then the various components of the present invention and their composition methods are introduced, and then the use embodiments, features, and benefits of the present invention are introduced as follows:

Please refer to Figures 4, 5, and 6, the user can touch the switch 22 at any part of the body to make the digital coil 32 conductive, so that the digital coil 32 repels the magnetic strip 21, and The force is greater than the magnetic repulsive force of the magnetic attraction force between the magnetic strip 21 and the metal body 40. Therefore, the door panel 20 can be pushed open by the magnetic repulsive force generated by the number of coils 32 to form the door panel 20 to automatically open.

Please refer to Figures 7, 8, and 9, when the door panel 20 is automatically opened, the door panel elastic opening mechanism can be activated, and the torsion spring 73 causes the door panel 20 to generate an outward opening elastic force, that is, the rotating shaft 70 continues to rotate. At this time, the arc-shaped portion 721 of the second sleeve 72 rotates with the rotating shaft 70 and guides the arc-shaped groove 62 to move downwards smoothly, so as to reduce the frictional resistance of the rotating shaft 70, thereby increasing The angle at which the door panel 20 opens outward.

The beneficial benefits produced by the present invention are:

It allows the user to easily and conveniently open the refrigerator by simply touching the switch 22 with his body when it is inconvenient to open the refrigerator door 20 with his hands while holding food or other problems with his hands. , To enhance the practical functions of the refrigerator.

Please refer to FIG. 10, FIG. 11, FIG. 12, and FIG. 13. In one embodiment, the metal body 40 and the supporting member 30 are in an integral shape.

In this embodiment, the door panel 20 can also be configured to automatically open.

Please refer to FIG. 14, in one embodiment, the groove 12, the supporting member 30, and the metal body 40 are rectangular.

The above examples of this case are provided for convenience of explanation only, and should not be used to limit the meaning of this case, that is, all the various design changes made in accordance with the scope of the listed patent applications should be included in the scope of patents of this case.
