In addition, the coupling method of the first, second and third coupling protrusions 73a, 73b and 73c constitutes the seventh installation holes 74 at the lower end of the opening / closing cover 70 and the first, second and third coupling holes. Coupling projections 73 may be easily achieved through a method of bolting by configuring each screw portion (not shown).

Looking at the operation of the present invention according to the configuration as described above are as follows.

First, when cooking is started using the steam oven 2 having the suction tube opening and closing device of the combination steam oven of the present invention, the steam is filled inside and condensation occurs, in which case, the controller (not shown) The suction pipe 1 is automatically opened and closed by the control of the outside, and the outside air is introduced into the cooking chamber 4 by the operation of the fan installed inside the cooking chamber 4, and the cooking chamber 4 is operated by such an operation. A part of the steam filled in is forced out.

Hereinafter, such an operation will be described in more detail with reference to FIG. 6 or 7.

When the steam is filled in the cooking chamber 4 and condensation occurs as described above, as shown in FIG. 6, the rotating shaft 31 is operated to operate the driving motor 30 under control of a controller (not shown). Rotate clockwise.

In addition, the rotation operation cam 40 and the driving cam 50 coupled to the rotation shaft 31 rotate in conjunction with the rotation shaft 31. At this time, the rotation operation cam 40 is eccentrically rotated, so as to be eccentric. The rotating operation unit 60 hinged between the bracket 10 and the auxiliary bracket 20 by the rotating operation cam 40 to rotate is rotated in the clockwise direction based on the hinge axis to the opening and closing cover 70 It acts to lift the first and second coupling protrusions 73a and 73b, whereby the opening and closing cover 70 is raised.

Therefore, outside the air through the air intake hole 72 formed on both sides of the opening and closing cover 70, the closing opening 71 of the opening and closing cover 70, which is blocking the suction pipe 1, the cooking chamber (4) It will flow inside. Here, the inflow of outside air is caused by the suction force of the fan 5 because the fan 5 configured in the cooking chamber 4 is always operated.

In addition, when the opening and closing cover 70 rises as described above, the third coupling protrusion 73c formed at one side of the lower end of the opening and closing cover 70 is formed in the guide hole 13a of the guide part 13 configured in the bracket 10. Since ascending while guided while being fitted, the opening and closing cover 70 is easily climbed without being caught or tilted.

In addition, the upward movement of the opening and closing cover 70 continuously occurs until the first predecessor 43 is in contact with the sensing hole 42 formed in the rotary operation cam 40, and the sensing hole 42 and the first When the sensor 43 comes into contact, the operation of the driving motor 30 is stopped to maintain the suction pipe 1 in an open state.

On the other hand, when the steam filled in the cooking chamber 4 is partially discharged to eliminate the need for inflow of air, the above-described opposite action occurs and the suction pipe 1 is closed, which will be described in detail with reference to FIG. 7. As described above, the driving motor 30 operates under the control of the controller so that the rotation shaft 31 rotates clockwise again.

Then, the rotary operation cam 40 and the driving cam 50 coupled to the rotary shaft 31 is rotated in conjunction with the rotary shaft 31, in this case the rotary operation cam 40 is eccentric rotation, The rotary actuator 60 hinged between the bracket 10 and the auxiliary bracket 20 is rotated in a clockwise direction based on the hinge axis.

In addition, at this time, since the force for pushing up the rotary operation unit 60 by the rotary operation cam 40 which rotates eccentrically disappears, the first and second coupling protrusions 73a and 73b of the opening and closing cover 70 are lifted. The lifting force disappears and the opening / closing cover 73 is lowered, whereby the suction pipe 1 which was opened is blocked by the closing opening 71 formed in the opening / closing cover 70 so that the outside of the cooking chamber 4 is no longer outside. No air will enter.

In addition, when the opening and closing cover 70 is lowered as described above, the third coupling protrusion 73 is formed at one side of the lower end of the opening and closing cover 70 in the guide hole 13a of the guide part 13 configured in the bracket 10. If the guide is inserted while being lowered, the opening and closing cover 70 is easily lowered without being caught or tilted. Here, the rotation operation unit 60 is caught in the upper portion of the bracket 10 can be prevented by the mounting insertion hole (shown in Figure 4: 15) configured on the upper portion of the bracket 10, the rotation operation portion ( 60) it is possible to achieve an easy operation without a jamming phenomenon.

In addition, the lowering operation of the opening and closing cover 70 continuously occurs until the first predecessor 43 is in contact with the sensing hole 42 configured in the rotary operation cam 40, and the sensing hole 42 and the first When the sensor 43 comes into contact, the operation of the driving motor 30 is stopped to maintain the suction pipe 1 in an open state.

In addition, when the driving motor 30 continues to rotate due to an unexpected situation such as the first sensor 43 malfunctioning, the sensing protrusion 61 protruding from the lower side of the rotation operating part 60. The function of stopping the rotation of the drive motor 30 through the contact with the second sensor 62 is imposed so that the opening and closing of the suction pipe (1) can be more easily performed without malfunction.

As described above, using the suction pipe opening and closing device of the combination steam oven of the present invention, it is possible to simply install on the outside of the suction pipe 1 without welding or penetrating the suction pipe 1 to increase productivity, It is easy to check the operation operation, it is possible to check the presence of abnormality and quick maintenance in case of failure, and to effect the opening and closing operation of the suction pipe (1) without malfunction.
