However, as described above, when the door suddenly enters the groove at the position where the door is opened about 10 degrees, and the elasticity of the second spring does not work, the door is closed suddenly, not only very loud noise is generated but also the door is easily broken. There is a risky problem.

That is, the roller guide, the roller, the second spring, the groove part is opened by the resistance of the oven door is opened more slowly about 10 degrees, but when it is closed, it is opened slowly, but when the door is closed, it is suddenly closed and there is a risk of noise and door breakage. will be.

In addition, if the elasticity of the first spring is too strong, the door may be too strongly closed when the door is closed, thereby causing damage. Therefore, the elasticity of the first spring may not be increased by a certain amount, so that the user may slightly push to close the door in the opened state. Since the door is kept open without being closed, there is an inconvenience in that the user needs to hold the door to the end to close the door.

Accordingly, an object of the present invention is to solve the above problems, and to close the door slowly to prevent noise generation and door breakage prevention, as well as to automatically close when the door is slightly pushed in the open state. In providing a door hinge device.

In order to achieve the above object, the present invention is fixed to the door of the oven, the hinge shaft is provided at the bottom and the lower end of the door member and the roller member and the groove is formed, the hinge shaft is installed on the main body of the oven Door hinge device for an oven comprising a housing having one end coupled to the door member, a link member having one end coupled to the door member with a first hinge, and a first spring installed to apply elasticity when the link member is pulled out. To

When the roller is pushed by the door member and moved away from the door member while being installed at the end of the guide member installed in the housing and the roller is installed, the roller is moved slowly by the hydraulic resistance and the hydraulic resistance is not generated in the opposite direction. And a return spring installed between the damper member and the roller, the roller being pushed toward the door member.

As described above, in the present invention, when the door is slightly pushed at a certain angle when closing the door of the oven, the roller is automatically closed by slowly pushing the roller guide of the door member due to the elasticity of the return spring and the first spring. It is an advantage to maintain the sealing force of the door by rapidly closing the elasticity of the first spring when entering.

1, 2 and 3 are a perspective view, an exploded perspective view and a cross-sectional view of the door hinge device for an oven according to the present invention, which is installed at the end of the guide member 59, in which the roller 58 is installed, and the housing 52. And a damper member (1) fixedly installed at the roller 58 to move slowly by the hydraulic resistance when the roller 58 is pushed by the door member 51 to move away from the door member, and to have no hydraulic resistance in the opposite direction. The damper member 1 and the roller 58 is installed between the roller 58 is composed of a return spring (2) installed to push the door member 51 side.

That is, when the door is opened and the roller 58 is pushed by the roller guide 61 of the door member 51, the hydraulic resistance is generated from the damper member to open the door slowly, and the door returns when the door is closed. The roller 58 slowly pushes the roller guide 61 due to the elasticity of the spring 2 and the first spring 56. When the user pushes the door slightly in this state, the door member is opened by the aforementioned force. The door 51 is configured to close automatically while moving in the closing direction.

The damper member 1 is provided in the housing 3 and is capable of reciprocating piston 4 and the first and second chambers inside the housing 3 when the piston 4 moves to the right in the drawing. It is composed of opening and closing means configured to prevent the flow of oil between (C1, C2) to generate a large hydraulic resistance force and to move the oil smoothly when moving to the left.

The opening and closing means is accommodated in the seat portion 5 formed in the piston 4, the seat portion 5 is moved to the left and right in accordance with the movement of the piston 4 and the piston 4 is the right Ring-type valve body 6 which blocks oil from flowing into the first and second chambers C1 and C2 when moving to the upper side, and oil moves to the valve body 6 when the piston 4 moves to the left. It consists of an oil hole 7 formed in the piston 4 to flow without being blocked by.

Of course, even if the oil hole 5 is blocked by the valve body 6, the oil is finely moved to other parts, so that the piston 4 can move slowly.

Referring to the operation and effect of the present invention as described above, the user opens the door to use the oven bar, in the closed state, as shown in Figure 3, the roller 58 is the groove portion of the door member 51 62), the piston 4 is pulled to the left side by the elasticity of the return spring 2.

In this state, since the valve body 6 is on the right side of the seat part 5, the oil can easily flow through the oil hole 7, and when the door is opened, the door member as shown in FIG. 5 is opened. The roller guide 61 of 51 causes the roller 58 to be pushed, which causes the piston 4 to move to the right in the drawing.

When the piston 4 moves to the right side, the valve body 6 is pushed to the left side to block the inner surface of the seat part 5 and the housing 3. As a result, the first and second chambers C1, Oil will not flow between C2).

When the flow of oil is blocked, the resistance of the oil is generated, which makes it more difficult to open the door, thereby preventing the user from quickly opening a high temperature oven and preventing a burn or the like.

When the roller 58 passes through the roller guide 61 while opening the door, the roller 58 moves again to the left side by the elasticity of the return spring 2, and the piston 4 connected thereto also moves to the left side. When the bar 4 moves to the left side, oil is not blocked by the valve body 6 as shown in FIG. 4, so that the door can be opened more easily.

When the door is closed while the door is open, the door closes relatively quickly in a state in which the roller 58 does not touch the roller guide 61, but when the roller 58 touches the roller guide 61, the roller 58 is roller guide 61. It is pushed back by the right side and the piston 4 is moved to the right.

When the piston 4 moves to the right, the flow of oil is blocked by the valve body 6 as shown in FIG. 5, so that the door is closed slowly.

That is, when the door is opened at a predetermined angle, for example, about 10-30 degrees, oil resistance is formed by the damper member 1 so that the door is slowly closed or opened.

When the roller 58 passes over the groove 62 of the door member 51 in a state in which the door is slowly closed, the roller 58 is pushed to the left by the elasticity of the return spring 2, which causes the damper member ( The piston 4 of 1) moves to the left.

When the piston 4 moves to the left side, the resistance of the oil is not generated, so that the door can be closed more quickly.

That is, when the door is in a slowly closed state, for example, when the door is opened at about 0-5 degrees, oil resistance does not occur so that it closes quickly, the sealing force can be maintained by reducing the sealing force when the door is slowly closed. Will be.

In particular, when the door is kept open as shown in FIG. 4, when the user slightly pushes the door, the roller 58 presses the roller guide 61 by a relatively weak force by the return spring 2. Therefore, the door is automatically closed by the elasticity of the damper member 1, the return spring 2 and the first spring (6).

That is, in the prior art, the door was held in the open state by hand and closed the door. However, in the present application, the door is automatically closed simply by slightly pushing the door, making it more convenient to use.
