Description

Technical Field

[0001] This utility model relates to an oven door, specifically an oven with adjustable closing force. Background Technology

[0002] Ovens are widely known as modern household appliances, commonly used in home kitchens. A typical oven consists of a cabinet containing a baking cavity, which is sealed by a door. Traditional oven doors typically have a fixed closing force, controlled by springs or hinges. This force is predetermined during manufacturing and cannot be adjusted. Consequently, a specific oven door corresponds to a specific oven model, and the closing force cannot be adjusted to suit individual user or oven type needs. Users who prefer a lighter closing force may find the door not fully closed, posing a safety hazard. Conversely, elderly users or children with unstable hand control may close the door too forcefully, causing the door to collide with the oven body, potentially damaging it and shortening its lifespan. Because the closing force is not adjustable, if the door's spring or hinge system malfunctions or ages, the entire system often needs to be replaced. This is difficult, costly, and complex, hindering widespread adoption. Utility Model Content

[0020] The present invention will be further described in detail below with reference to the accompanying drawings. An oven with adjustable closing force includes a body 1 and an inner liner 2 placed therein. The front end of the body 1 is open, and a first door 3 and a second door 4 are installed over the open end. An annular mounting cavity is formed between the inner liner 2 and the inner wall of the body 1. The first door 3 and the second door 4 are connected to the body 1 in a split manner by door hinges 10 fitted into the mounting cavity.

[0021] The mounting cavity is also hinged to a swing rod 7. The free end of the swing rod 7 is hinged to a first pull rod 8 and a second pull rod 9. The other end of the first pull rod 8 is hinged to the first box door 3, and the other end of the second pull rod 9 is hinged to the second box door 4. An adjustment seat 6 is installed on one side of the mounting cavity, and several external adjustment holes 61 are opened through the end face of the adjustment seat 6.

[0022] The first pull rod 8 and / or the second pull rod 9 are provided with a plurality of inner adjustment holes 15. One end of the adjustment spring 5 is connected to the outer adjustment hole 61 and the other end is connected to the inner adjustment hole 15. The adjustment spring 5 generates a pulling force to pull the first pull rod 8 or the second pull rod 9 to move, thereby generating the power to pull the box door to close.

[0023] The adjusting spring 5 is a tension spring, with hooks at both ends. The hooks are respectively hooked onto the outer adjusting hole 61 and the inner adjusting hole 15.

[0024] The inner end faces of the first door 3 and the second door 4 are provided with hinge seats 13, and the first pull rod 8 and the second pull rod 9 are hingedly installed on the hinge seats 13.

[0025] The mounting cavity is provided with a hinge shaft 14, and one end of the swing rod 7 is hinged to the hinge shaft 14. The swing rod 7 swings synchronously to push the first pull rod 8 and the second pull rod 9 to move, thereby pushing the first box door 3 and the second box door 4 to open and close synchronously.

[0026] The swing arm 7 has a first reinforcing rib plate 71 and a second reinforcing rib plate 72 bent on its two long sides. The swing arm 7, the first reinforcing rib plate 71 and the second reinforcing rib plate 72 are integrally stamped from metal sheet.

[0027] The first tie rod 8 and the second tie rod 9 have a first reinforcing plate 11 and a second reinforcing plate 12 bent on their two long sides. The first tie rod 8 and the second tie rod 9, along with the first reinforcing plate 11 and the second reinforcing plate 12, are integrally stamped from metal sheets.

[0028] Working principle: An annular mounting cavity is formed between the inner cavity and the inner wall of the oven. The first and second doors are hinged together by door hinges installed at the port of the mounting cavity. The first and second doors are connected to the oven body in a split manner.

[0029] The device includes a swing arm hinged within the mounting cavity. The fixed end of the swing arm is hinged to the mounting cavity, while the free end is hinged to a first pull rod and a second pull rod. The other end of the first pull rod is hinged to the first door, and the other end of the second pull rod is hinged to the second door. Pulling either door will cause the swing arm to move the first and second pull rods synchronously, thus achieving the synchronous opening and closing of the two doors.

[0030] It should be noted that, in order to adjust the closing force of the cabinet door, an adjusting seat is installed on one side of the mounting cavity, and several external adjusting holes are opened through the end face of the adjusting seat. Corresponding to the external adjusting holes, several internal adjusting holes are provided on the body of the first pull rod. One end of the adjusting spring is connected to the internal adjusting hole, and the other end is connected to the external adjusting hole. The adjusting spring generates a relative pulling force, which constantly pulls the first pull rod to move, thereby generating a closing force to close the cabinet door. The internal adjusting holes can be located on the body of the first pull rod, the body of the second pull rod, or both the first and second pull rods. Users can choose the appropriate connection method according to their needs.

[0031] Because there are multiple adjustment holes, users can adjust the door closing spring force according to their own usage habits (the force of opening and closing the door, the frequency of use, etc.) or different oven models, thereby avoiding the limitations of the fixed spring force in the existing technology, which cannot meet different needs, and improving the versatility and adaptability of the oven.

[0032] By adjusting the door's closing spring force, inconvenience and safety hazards caused by excessively strong or weak closing spring force are avoided during oven use. This ensures the oven door closes securely, prevents heat loss, improves the oven's thermal efficiency, and also prevents damage from impacts, effectively protecting components and extending their lifespan. Furthermore, after prolonged use, if the adjusting spring ages or becomes damaged, a suitable adjustment hole can be connected, reducing the frequency of spring replacement and lowering maintenance costs. The installation and adjustment of the adjusting spring are convenient and quick, requiring no complicated operations; its simple and stable structure improves the overall stability and reliability of the oven door.

[0033] The swing arm has a first reinforcing rib and a second reinforcing rib bent along its two long sides. The swing arm and the first and second reinforcing ribs are integrally stamped from sheet metal. The first and second pull rods have a first reinforcing plate and a second reinforcing plate bent along their two long sides. The first and second pull rods and the first and second reinforcing plates on them are integrally stamped from sheet metal. The structure is simple, the manufacturing cost is low, and the overall competitiveness of the oven is improved. Therefore, it can be widely promoted.
