[

FIG. 3 is a rear view showing a rear surface of a door according to an embodiment of the present invention, and FIG. 4 is an enlarged view of the "A" portion of FIG. 5 is a side cross-sectional view showing the door closed state of the door body shown in FIG. 3, FIG. 6 is a view showing an opening process of the door body shown in FIG. 5, And Fig.

3 to 5, the door 100 provided in the cooking apparatus of the present embodiment is provided in a form of opening and closing the chamber 31 in a pull-down manner in which the upper end of the door 100 is vertically rotated about the lower end A door body 110, a hinge member 120, an elastic member 130, and a damper member 140.

The door body 110 is formed to have a predetermined length, width, and thickness, and may have a hexahedron shape having a predetermined thickness as a whole.

The door main body 110 may include a door frame 111 forming a rear surface of the door 100 and a door panel 113 forming a front surface and an upper surface and both side surfaces of the door 100.

An opening window is formed inside the door frame 111 and the door panel 113 so as to be visually distinguishable inside the chamber 31. An opening window is formed between the door frame 111 and the door panel 113, A door glass 115 provided to cover the window may be installed.

The door body 110 rotates in one direction or another direction about the lower end of the door body 110, that is, in the vertical direction about the lower end, and opens and closes the chamber 31 formed in the apparatus main body 10.

The hinge member 120 is installed on the apparatus main body 10 so as to be positioned below the chamber 31 and rotatably couples the door main body 110 to the apparatus main body 10. [ The hinge member 120 may include a hinge shaft 121 and an interference unit 125.

The hinge shaft 121 is provided in the form of a shaft having a length extending in the left-right direction. The hinge shaft 121 is fixed to the machine body 10 by being inserted into the machine body 10. The hinge shaft 121 has a rotation center of the door body 110, 110 are hinged together.

The interference portion 125 is provided so as to protrude from the hinge shaft 121. The interference part 125 is a part where sliding movement is possible between the hinge member 120 and the damper member 140. The structure and operation of the interference part will be described later.

The elastic member 130 is provided at a joint portion between the main body 10 of the apparatus and the hinge shaft 121 and the door main body 110. In this embodiment, the elastic member 130 is illustrated as being provided in the form of a torsion spring in which the elastic member 130 is elastically deformed by twisting. The elastic member 130 thus provided is exposed to the front of the door body 110 And is disposed on the rear surface of the door body 110 so as not to be exposed.

The elastic member 130 is installed such that one end of the elastic member 130 is fixed to the hinge member 120 and the other end of the elastic member 130 is fixed to the door main body 110. The elastic member 130 installed in this manner can generate an elastic force that is torsional and interlocked with the rotation of the door main body 110 and attenuates the rotational force of the door main body 110 rotating in one direction, that is, the downward direction.

By the action of the elastic member 130, the door body 110 receives a resistance which hinders the rotation in the downward direction when the door body 110 is rotated downward, so that the rotation speed is reduced and the door body 110 can be smoothly spread forward. In particular, since the deformation of the elastic member 130 becomes greater as the door body 110 rotates in the lower direction when the door body 110 rotates, the resistance becomes stronger.

The damper member 140 is installed on the side surface of the door main body 110 so as to be positioned inside the thickness direction of the door main body 110 and is coupled to the hinge member 120. The damper member 140 is provided to generate a damping force for damping the rotational force of the door main body 110 and is linked to the rotation of the door main body 110 to change the connection state with the hinge member 120, .

As an example, the damper member 140 may be provided in the form of an air damper or a hydraulic damper including a cylinder 141, a rod 143 and a piston (not shown).

The cylinder 141 is installed on the side surface of the door main body 110 and a space filled with the fluid is formed in the cylinder 141.

In the cylinder 141, a rod 143 is provided to be able to protrude and retract. The rod 143 is provided so as to be positionally changeably connected to the hinge member 120. One end of the rod 143 is inserted into the cylinder 141 to be projected into and retracted from the cylinder 141, Is exposed to the outside of the cylinder 141 so as to be in contact with the hinge member 120.

The rod 143 is movably provided in the damper member 140 so that the protruding and retracting length is changed according to the position connected to the hinge member 120. The damper member 140 generates a resistance force acting in a direction to prevent the movement of the rod 143, and the resistance force generated in this way acts to reduce the moving speed of the rod 143 moving along its lengthwise direction do.

As described above, the resistance force provided by the damper member 140 can be generated by a piston (not shown) provided inside the cylinder 141. [ The piston is movably provided in the cylinder 141 along the longitudinal direction of the rod 143 and is engaged with the other longitudinal side of the rod 143 and interlocked with the rod 143 to move inside the cylinder 141 .

The piston moved in accordance with the movement of the rod 143 receives resistance by the fluid filled in the cylinder 141 and decreases the moving speed thereof to generate a damping force to prevent the movement of the rod 143 coupled with the piston .

At this time, it is preferable that the piston is configured to receive a resistance that stops the rod 143 only when the rod 143 moves in a direction in which the length of the protruding and retracting of the rod 143 is shortened. Since such a configuration can be easily implemented by a person skilled in the art A detailed description thereof will be omitted. However, even if the length of the protrusion and the protrusion of the rod 143 is short or long, there is no significant effect on realizing the damping effect according to the present invention.

The pivoting angle at which the door body 110 can be pivoted downward is associated with the protruding and retracting length of the rod 143 when the door body 110 is pivoted downward to open the chamber 31. The distance between the damper member 140 and the hinge member 120 installed on the door body 110 must be shortened so that the length of the rod 143 protruding from the door body 110 is reduced as the door body 110 rotates downward, The rotation of the door main body 110 in the downward direction is restricted.

When the door body 110 is rotated in the downward direction, the rod 143 moves in a direction in which the protruding / retracting length is shortened in conjunction with the rotation of the door body 110, Direction can be continuously performed.

The resistance force generated by the damper member 140 acts in a direction to prevent the movement of the rod 143 while the rod 143 moves in the direction in which the protruding / There is a speed difference in which the reduction in length is made at a speed slower than the speed at which the door body 110 is rotated in the downward direction.

This speed difference causes a resistance force to prevent the rod 143 from rotating the door main body 110. The resistance force acts as a damping force for damping the rotational force for rotating the door main body 110 in the downward direction. In this way, the door main body 110 in which the rotational force is attenuated due to the damping force applied to the door main body 110 is allowed to smoothly spread forward and decelerate the rotational speed.

On the other hand, the change in the protruding and retracting length of the rod 143 can be caused by a change in the connection state between the rod 143 and the hinge member 120 in the process of rotating the door main body 110.

According to the present embodiment, the hinge member 120 is provided with the interference part 125 that interferes with the rod 143 so that the protruding and retracting length of the rod 143 changes. The interference between the rod 143 and the hinge member 120 is detected by the interference portion 125. The interference portion 125 includes a contact surface 126 for interference with the rod 143, And are in contact with each other.

The interference portion 125 including the contact surface 126 is formed such that the distance between the contact surface 126 and the damper member 140 changes according to the rotation angle of the door main body 110.

More specifically, the interference portion 125 is formed so that the distance between the contact surface 126 and the damper member 140 becomes shorter as the door body 110 is rotated in one direction to open the chamber 31, that is, in the lower direction .

In other words, the interference part 125 is formed to have a contact surface 126 extending along the direction in which the door main body 110 is rotated, and the contact surface 126 is formed in the lower part of the interference part 125, 140, respectively.

6 and 7, as the door body 110 is rotated in the downward direction, the rod 143 pushed by the interference portion 125 pushes the protruding / As shown in Fig.

As an example, an elastic spring (not shown) may be provided in the damper member 140 to generate an elastic force in a direction in which the rod 143 protrudes, that is, in a direction in which the protruding / have.

The elastic spring may be provided in such a manner as to elastically support the piston in the direction in which the rod 143 is projected from the inside of the cylinder. This elastic spring is compressed by the piston moved in the direction in which the protruding and retracting length of the rod 143 is shortened and then the door body 110 is rotated in the upward direction so that the interference between the rod 143 and the interference part 125 It is elastically restored when it is released and can generate an elastic force in the form of pushing out the piston.

As another example, the door 100 may be provided in a form further including the engaging portion 150, as shown in Figs.

The coupling unit 150 is provided with a structure in which the rod 143 is slidably coupled to the interference unit 125 so that the interference state between the rod 143 and the interference unit 125 is maintained.

One side of the engaging portion 150 is slidably coupled to the interference portion 125 to be slidable along the direction in which the contact surface 126 extends and the other side of the engaging portion 150 is engaged with the contact surface 126, And is hinged to the other side in the longitudinal direction of the rod 143 opposed thereto.

The rod 143 can be connected to the hinge member 120 while maintaining a stable state of engagement with the interference part 125 by the coupling part 150. Thus, regardless of the presence or absence of the elastic spring, 110 can move in the direction in which the protruding and retracting length of the rod 143 is extended in conjunction with the upward turning of the rod 143. [

4 and 5, the damper member 140 is installed on the side surface of the door body 110 and does not protrude outward in the thickness direction of the door body 110, And the rod 143 provided on the damper member 140 is also positioned inside the door body 110 in the thickness direction.

The movement of the rod 143 is along the direction parallel to the longitudinal direction of the door main body 110 in the thickness direction of the door main body 110, In the thickness direction.

That is, the damper member 140 of the present embodiment is not exposed to the outside of the door body 110 while being hidden on the side surface of the door body 110 so as not to protrude outside the door 100, Lt; RTI ID = 0.0 > a < / RTI >

In addition, in the door 100 of the present embodiment, the elastic member 130 is also disposed on the rear surface of the door body 110 so as not to be exposed to the front of the door body 110.

That is, all of the configurations for providing the damping force to the door body 110 are provided so as not to be exposed to the outside of the door body 110, and the operation thereof can be made not to be exposed to the outside of the door body 110, It is possible to effectively control the opening speed of the door 100 without deteriorating the appearance of the cooking utensil 100

Hereinafter, the functions and effects of the door according to the present embodiment and the cooking appliance having the door will be described.

That is, the door main body 110 rotates in the downward direction to open the chamber 31, and rotates upward to close the chamber 31.

When the door body 110 rotates in the downward direction to open the chamber 31, the moment acts weakly at the beginning of the pivoting movement of the door body 110. However, as the door body 110 rotates, Gradually becomes stronger.

A strong moment acts on the door main body 110 when the door main body 110 reaches the latter half of the rotation of the door main body 110 having opened the chamber 31. This causes the door main body 110 to pivot suddenly And the door body 110, which completely opens the chamber 31, may vibrate in the up and down direction and cause a rattling phenomenon.

The elastic member 130 is installed such that one end of the elastic member 130 is fixed to the hinge member 120 or the door body 110 and the other end of the elastic member 130 is fixed to the door body 110. The elastic member 130 installed in this manner can generate an elastic force that is torsional and interlocked with the rotation of the door main body 110 and attenuates the rotational force of the door main body 110 rotating in the downward direction.

At this time, the elastic force provided by the elastic member 130 is set to an appropriate level that can suppress the sudden opening of the door 100 in consideration of the rotational force of the door main body 110.

By the action of the elastic member 130 provided as described above, the door body 110 is allowed to open the chamber 31 while being decelerated in the downward direction and smoothly spread forward.

In order to solve this problem, in this embodiment, in addition to the elastic force provided by the elastic member 130, a damping structure is provided in which the damping force provided by the damper member 140 acts together in the turning process of the door body 110. [

The damper member 140 is linked to the rotation of the door main body 110 and changes its connection state with the hinge member 120 to generate a damping force acting to damp the rotational force of the door main body 110 rotating in the downward direction .

The damping force provided by the damper member 140 as described above is applied to the door body 110 together with the elastic force provided by the elastic member 130 while the door body 110 is rotated downward to open the chamber 31 The door body 110 can be smoothly unfolded by being applied to the door body 110 by the door body 110 in a later rotating period of the door body 110 in which the door body 110 completely opens the chamber 31, 110). ≪ / RTI >
