Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a door opening structure that can be suspended at any angle. Background Technology

[0002] In the field of modern home appliances, microwave ovens and mini-refrigerators are indispensable devices in kitchens and living spaces, and their user-friendly design and functionality directly affect the user's daily experience. However, in the existing designs of microwave ovens and mini-refrigerators, the door opening and closing mechanism generally has a significant deficiency: during the opening process, the door can often only remain stable at two extreme positions, either fully open or fully closed, lacking the ability to hover at any intermediate angle.

[0003] This design flaw causes numerous inconveniences in daily use. For example, in microwave ovens, users may need to briefly open the door during heating to check the food's condition or add seasonings. However, traditional doors cannot be left open, forcing users to hold the door with one hand and operate the appliance with the other, which is both inconvenient and poses a safety hazard. Similarly, in mini-fridges, users may frequently open the door to retrieve items. If the door cannot be left open, it not only takes up space but may also cause fingers to be pinched or items to fall due to sudden door slamming.

[0004] Furthermore, traditional door designs are inadequate for situations requiring a certain level of ventilation or where minimizing cold air loss is desired. Users cannot flexibly adjust the door's opening angle to achieve optimal ventilation or insulation, which to some extent affects the energy efficiency and lifespan of electrical appliances.

[0005] While some door designs on the market attempt to address this issue, they often have complex structures, increasing manufacturing costs, and the stability and reliability of hovering are difficult to guarantee. Some designs can achieve hovering at a certain angle, but the hovering angle is limited and cannot meet the diverse usage needs of users. Utility Model Content

[0054] It should be noted that the design of the limiting groove 63 ensures the stable locking of the outward-opening door 3 in the closed state, while the design of the smooth end face reduces the friction between the sliding connecting plate 61 and the door hook roller 12, improving the smoothness of opening and closing the door.

[0055] The working principle of this utility model is as follows: Through a specific mechanical structure design, the outward-opening door 3 can be suspended at any angle during the opening process. Specifically, the structure includes a core assembly 1, which is fitted with a main body shell 2. The core assembly 1 has a chamber for storing items, and the outward-opening door 3 is rotatably installed at the opening of the chamber. The outward-opening door 3 is connected to the core assembly 1 through a door hook seat 5 and a door hook connecting plate 6. The door hook connecting plate 6 is then connected to a fixed base plate 8 through a door hook spring 10. At the same time, roller shafts 11 and door hook rollers 12 are also installed on both sides of the core assembly 1, and the door hook connecting plate 6 is slidably connected to the door hook rollers 12.

[0056] During the opening process, the user pulls the door handle 4, and the outward-opening door 3 rotates around the door hinge plate 7. The door hook connecting plate 6 then slides on the door hook roller 12. At this time, the door hook spring 10 is stretched, generating a certain resistance. This resistance is related to the opening angle and speed of the outward-opening door 3. By adjusting the elasticity of the door hook spring 10, the outward-opening door 3 can be suspended at any angle without the need for an additional locking mechanism.

[0057] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
