Description

Technical Field

[0001] The utility model relates to a hardware accessory, in particular to a hidden door hinge system. Background Art

[0002] In modern kitchen equipment, ovens have become an indispensable part, and their design must not only meet functional requirements, but also take into account aesthetics and user experience. However, in the prior art, there are some problems in the design of oven door hinges, which affect the overall appearance and user experience.

[0003] Most ovens on the market currently use the traditional external hinge system. Although this design can meet the opening and closing functions of the oven door to a certain extent, the hinge assembly is exposed when the oven door is opened, which not only destroys the overall appearance of the oven, but also easily accumulates oil and dust, increasing the difficulty of cleaning. In addition, the external hinge is easily impacted by external forces during long-term use, causing damage to the hinge and affecting the normal service life of the oven.

[0004] These external hinge systems usually include a main arm fixed to the box body and a hinge arm installed on the door, which is connected to the main arm through a hinge point. When the door is opened, the hinge arm rotates along the hinge point, but because both the hinge arm and the main arm are exposed, the user not only has to face the unsightly hinge during operation, but also has to be careful to avoid collisions. In addition, the traditional hinge system lacks an effective air avoidance design. When the door is closed, interference between the hinge arm and the box body is likely to occur, resulting in the door not being able to close smoothly or damage to the hinge.

[0005] In order to solve these problems, some improved hinge designs have appeared on the market, such as hidden hinge systems. These systems can hide the hinges inside the oven when the oven door is closed, without affecting the aesthetic appearance of the oven. However, the existing hidden hinge design still has certain structural complexity and manufacturing difficulties, and the installation and maintenance costs are high. In actual use, the problem of hinge exposure has not been completely solved, so it is necessary to make further improvements to it. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a hidden door hinge system which is simple in structure and easy to use. Through innovative design, the hinge can be hidden when the door is opened, thereby improving the overall aesthetics of the oven, and the door can be opened and closed smoothly, thereby avoiding exposure and damage of the hinge components.

[0007] The utility model aims to achieve the following: a hidden door hinge system, which comprises a main arm body mounted on a box body and a hinge arm mounted on the door, the hinge arm being hinged to the main arm body, and the hinge arm rotating around the hinge point between the main arm body and the door to realize the opening and closing of the door;

[0008] The hinge arm includes a connecting portion hinged to the main arm body, a clearance portion at the other end of the connecting portion, the clearance portion is connected to the box door through the mounting portion, and the clearance portion and the connecting portion are distributed in a "V" shape to form a clearance groove between the two;

[0009] It also includes a decorative cover arranged on the box body, the decorative cover is provided with a mounting groove, and the hinge arm passes through the mounting groove and is connected with the box door.

[0010] The hinge arm is arranged in a sheet shape, and correspondingly, the width of the mounting groove is arranged to be greater than the thickness of the hinge arm.

[0011] The main arm body is also provided with a receiving groove, and when the box door is closed, the hinge arm extends into the receiving groove.

[0012] The main arm body is a groove-shaped structure with an opening at the bottom. A pulling arm is arranged in the main arm body. One end of the pulling arm is hinged to the hinge arm, and the other end is connected to a tension spring fixed in the main arm body. The tension spring generates tension to pull the hinge arm to always move in the closing direction.

[0013] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0014] 2. When the oven door is opened, the hinge body of the concealed oven door hinge system of the utility model is hidden under the decoration and not exposed to the outside. This design significantly improves the overall appearance of the oven and avoids the problem of traditional external hinges being exposed to the outside after the oven door is opened, which affects the appearance.

[0015] 3. The hinge arm is designed as a "V"-shaped structure, and an air avoidance groove is formed between the connecting part and the air avoidance part. When the door is opened, the air avoidance part effectively avoids interference with the decorative cover, so that the hinge system can still be opened and closed freely after the decorative cover is installed.

[0021] The present invention is further described in detail below with reference to the accompanying drawings. A hidden door hinge system comprises a main arm body 2 mounted on a box body 1 and a hinge arm 4 mounted on a door 3, wherein the hinge arm 4 is hinged to the main arm body 2, and the hinge arm 4 rotates around the hinge point between the main arm body 2 and the door 3 to open and close.

[0022] The hinge arm 4 includes a connecting portion 41 hinged to the main arm body 2, a clearance portion 42 located at the other end of the connecting portion 41, and the clearance portion 42 is connected to the box door 3 through a mounting portion 43. The clearance portion 42 and the connecting portion 41 are distributed in a "V" shape, and a clearance groove 44 is formed between the two.

[0023] The box body 1 further comprises a decorative cover 5 , which is provided with a mounting groove 51 , through which the hinge arm 4 passes to be connected with the box door 3 .

[0024] The hinge arm 4 is in a sheet shape, and correspondingly, the width of the mounting groove 51 is greater than the thickness of the hinge arm 4 .

[0025] The main arm body 2 is also provided with a receiving groove 21 , and when the door 3 is closed, the hinge arm 4 extends into the receiving groove 21 .

[0026] The main arm body 2 is a groove-shaped structure with an opening at the bottom. A pulling arm 26 is arranged inside the main arm body 2. One end of the pulling arm 26 is hinged to the hinge arm 4, and the other end is connected to a tension spring 27 fixed inside the main arm body 2. The tension spring 27 generates a pulling force to pull the hinge arm 4 to always move in the closing direction.

[0027] Working principle: When the user opens the door 3, the hinge arm 4 rotates around the hinge point between it and the main arm body 2. The connecting portion 41 of the hinge arm 4 is connected to the main arm body 2 through the hinge point, ensuring that the hinge arm 4 can rotate smoothly. The air avoidance portion 42 of the hinge arm 4 is fixedly connected to the door 3 through the mounting portion 43. When the hinge arm 4 rotates, the "V"-shaped structure between the air avoidance portion 42 and the connecting portion 41 forms an air avoidance groove 44, which effectively avoids interference between the hinge arm and the decorative cover, ensuring the smooth opening of the door.

[0028] The decorative cover 5 is mounted on the box body 1 and is provided with a mounting groove 51. When the hinge arm 4 rotates, it is connected to the door 3 through the mounting groove 51. The setting of the decorative cover 5 not only beautifies the appearance of the oven, but also protects the hinge system, so that the hinge arm always remains hidden during the rotation process, without affecting the overall appearance of the oven.

[0029] The main arm body 2 is a groove-shaped structure with an open bottom, in which a tension arm 26 and a tension spring 27 are arranged. One end of the tension arm 26 is hinged to the hinge arm 4, and the other end is connected to the tension spring 27 fixed in the main arm body 2. The tension spring 27 provides a continuous tension on the tension arm 26 to ensure that the hinge arm 4 is always subjected to a tension in the closing direction when the door 3 is closed. This design provides power for closing the door and maintains the sealing of the door after closing, avoiding heat leakage during use of the equipment and ensuring the thermal efficiency of the equipment.

[0030] In general, the concealed oven door hinge system of the utility model realizes the smooth movement of the oven door during opening and closing through reasonable structural design, while effectively hiding the hinge components, thereby improving the aesthetics and ease of use of the oven.
