In order to use the grain sprinkler according to an embodiment of the present invention for home use as a whole, miniaturization is required, and thus, the pressure cooker 110 and the pressure lid 120 also need to be smaller than the general grain sprinkler. On the other hand, even if the pressure cooker 110 and the pressure lid 120 is formed small, the pressure cooker 110 should be heated to a temperature suitable for the puffing condition, the heating source 130, the pressure cooker 110 in the process of repeating the heating and cooling And it is necessary to prevent the pressure lid 120 from being damaged by thermal deformation.

Therefore, the controller 700 may control the power supplied to the heating source 130 in a pulse width modulation (PWM) method based on the temperature of the heating source 130 sensed by the temperature sensing unit 135.

The pressure lid lifting unit 200 is installed on the second support frame 107 and the lifting drive source 210 to provide a rotational force, the operating rod 220 and the operation rod 220 is installed to be elevated on the first support frame 105 and the operation Lift control unit 250 for adjusting the lift of the rod 220 is included.

Lifting drive source 210 is rotatably controlled by the control unit 700, is installed on the upper portion of the main body 100 and rotates the operation cam (260 of Figure 5a or 270 of Figure 3) of the lifting control unit 250 Drive.

The operating rod 220 is installed on the front portion of the main body 100 by the first support frame 105 to be elevated on the pressure cooker (110). The operation rod 220 is elastically biased in the direction of rising on the pressure cooker 110 when the pressing force of the lifting control unit 250 is released. To this end, the present invention is provided on the outer periphery of the operating rod 220, and may further include a first elastic member 221 for providing an elastic force between the first support frame 105 and the operating rod 220.

Lifting control unit 250 includes an operation cam (260 of Figure 5a, 270 of Figure 3) driven by the rotational force of the lifting drive 210, the lifting and lifting drive source 210 of the operating rod 220 On / Off (On / Off) control to adjust the pressurization time at the compression top position (the position where the pressing force of the pressure lid 120 is the largest) of the pressure lid (120). To this end, the lifting control unit 250 further includes an operating cam position detecting unit 281 and a lifting control unit 285 for detecting the rotational position of the operating

cams

260 and 270 at the compression top position of the pressure lid. Can be. The elevating control unit 285 controls the

operation cams

260 and 270 at a constant speed so that the puffing grain is always rotated at a constant speed regardless of the input amount, type, and the like. Control the pause and stop time. Therefore, when performing puffing on grains requiring a relatively long puffing time, the rotation speed of the operation cam is not lowered, thereby reducing the time required for mode switching.

In addition, the lifting control unit 285 controls the lifting drive source 210 on / off based on the detection signal from the operation cam position detecting unit 281. Therefore, it is possible to adjust the time the operation cam stops at the compression top position of the pressure lid 120, it is possible to adjust the compression top position holding time according to the puffing time that varies depending on the type and conditions of grain. The lifting control unit 285 may belong to the control unit 700 for controlling the overall grain frying apparatus according to the embodiment of the present invention.

5a and 5b is a view showing an operating state of the operation cam according to an embodiment of the grain sprinkler of the present invention.

Referring to the drawings, the operation cam 260 according to an embodiment includes an operation cam body 261 and a trigger 265 installed in the operation cam body 261. The actuating cam main body 261 has a predetermined cam profile 261a to which the upper end of the actuating rod 220 comes into contact, and rotates by a rotational force provided by the lifting driving source 210. That is, the operation cam main body 261 is rotated at a constant speed by the elevating drive 210 except for a predetermined time stop at the compression similar position as shown in Figure 5b. Therefore, when the actuating cam main body 261 rotates, the actuating rod 220 along the cam profile 261a raises and lowers the height, thereby changing the mode of the puffing process. Since the position change of the cam profile 261a of the actuating cam main body 261 can be detected through the actuating cam position detecting unit 281, the lifting and lowering of the actuating rod 220 according to the rotation of the actuating cam main body 261 is precisely performed. Can be controlled. Here, the operation cam body 261 is shown as an example installed on the rotary shaft 211 of the elevating drive source 210, but is not limited thereto, and receives the rotational force provided from the elevating drive source 210 through a separate power transmission unit. It is also possible to install so that.

The trigger 265 is rotatably installed in the actuating cam body 261, thereby regulating or releasing the position where the actuating rod 220 rises out of the compression top position. That is, the trigger 265 is in contact with the actuating rod 220 at a predetermined section when the actuating cam main body 261 is rotated, and with respect to the actuating cam main body 261 in a predetermined section by the pressing force between the actuating cam body 261. While the relative rotation, the rise of the operating rod 220 is regulated for a certain time. Here, the operation cam main body 261 is formed with a trigger stop 263 to limit the rotation range of the trigger 265 to cause the operation rod 220 to immediately rise from the puffing start position. The puff start position indicates the position at which the pressure lid 120 starts to rise on the pressure cooker 110. As described above, the trigger stop 263 is formed to the trigger stop 263 as shown in FIG. 5A. At the position where the trigger 265 is engaged, the contact between the trigger 265 and the operation rod 220 is released momentarily. Therefore, as shown in 5b, the operation rod 220 may change the mode without causing a problem of hitting a part of the operation cam body 261.

Here, the actuating rod 220 includes a roller 225 in contact with the actuating cam body 261 or the trigger 265 at the upper end to mitigate friction, thereby actuating according to the rotational movement of the actuating cam body 261. The lifting of the rod 220 can be made smoothly. In addition, the damper 227 is provided in the lower portion of the first support frame 105 to prevent the noise generated by contacting the first support frame 105 to the pressure lid 120 during the lifting of the operation rod 220. It may further include.

Figure 6 is an exploded perspective view showing the lifting control unit 250 and the operating rod 230, including the operation cam 270 according to another embodiment of the grain sprinkler of the present invention, each of Figures 7a to 7d Figure is a view showing the operating state of the lifting control unit 250 and the operating rod 230 according to another embodiment of the grain sprinkler.

Referring to the drawings, the actuating cam 270 according to another embodiment includes an actuating cam body 271 and a pressing portion 273 protruding from the actuating cam body 271. The operation cam main body 271 is connected to the rotation shaft 211 of the lifting drive source 210, and rotates at a constant speed except for a predetermined time stop at the compression top position. Therefore, when the operation cam main body 271 rotates, the operation rod 230 changes the lifting height according to the position change of the pressurizing unit 273, thereby changing the mode of the puffing process. Since the rotation position of the actuating cam body 271 can be sensed through the actuating cam position detecting unit 281, it is possible to precisely control the lifting and lowering of the actuating rod 230 according to the rotation of the actuating cam body 271. That is, the operating cam position detecting unit 281 detects the rotation position of the operating cam body 271 based on the position mark 271a provided at a predetermined position of the operating cam body 271. Here, the operation cam body 271 is shown as an example installed on the rotating shaft of the elevating drive source 210, but is not limited to this installation is installed so that the rotational force provided from the elevating drive source 210 through a separate power transmission unit. It is also possible.

The pressurizing portion 273 is formed to protrude on the actuating cam body 271 to guide the compression, vapor discharge and puffing of the pressure lid 120 when the actuating cam body 271 is rotated. Here, the pressing unit 273 may be coupled to the pressing roller 274 rotatably installed. The pressing roller 274 can reduce the friction by rolling contact with the operation head 235 and the trigger lever 275 which will be described later.

In this embodiment, the operating rod 230 is installed at the end facing the pressing portion 273, may include an operation head 235 is formed with a locking step 237 on one side. Here, the operation head 235 may reciprocate in a width larger than the radius of the operation cam body 271 according to the rotational position of the pressing unit 273 as shown in FIG. 7A. Therefore, compared to the lifting control unit shown in Figures 5a and 5b, even if the installation height of the operation cam 270 is lowered, the lifting height of the operating rod 230 can be maintained the same or similar to the overall height can be lowered.

The lifting adjustment unit 250 may further include a trigger lever 275 rotatably installed on the second support frame 107 of the main body 100. The trigger lever 275 regulates vapor evacuation and puffing by interaction with the actuating head 235 and the pressurizing portion 273. To this end, the trigger lever 275 includes a lever body 277 and the engaging projection 279.

FIG. 7A illustrates an open state of the pressure cooker (110 of FIG. 1), that is, a puffing preparation state, in which case the operation head 235 does not interfere with the pressing unit 273 and the trigger lever 275.

7B shows the state of the actuating cam 270 and the actuating rod 230 when the actuating rod 220 is positioned at the compression top position, that is, the pressure applying state. The operation head 235 is pressurized by the pressurizing portion 273, while the pressure lid 120 maintains the compression firm position to pressurize the pressure cooker 110. In this case, the locking protrusion 279 is positioned on the locking step 237 to be spaced apart by a predetermined interval. In the state of FIG. 7B, the operating cam position detecting unit 281 detects the position of the operating cam 270 and provides the detected position to the control unit 700. The control unit 700 controls the lifting drive source 210 on / off in consideration of the detection signal from the operation cam position detecting unit 281 and the user setting state through the UI unit 600, thereby maintaining the pressure applying state. Adjust

Here, when the operation cam 270 rotates from the state of FIG. 7A to the state of FIG. 7B, the operation head 235 is disposed on one side of each of the operation head 235 and the locking protrusion 279 so that the operation head 235 does not interfere with the trigger lever 275. An inclined surface is formed. Therefore, the trigger lever 275 rotates while the inclined surface of the actuating head 235 contacts the inclined surface of the engaging protrusion 279 when the actuating rod 230 descends, so that the actuating rod 230 does not interfere with the trigger lever 275. You can descend naturally.

7C illustrates a state in which the operation rod 220 is restrained by the locking protrusion 279, that is, a steam discharge state. After a predetermined time elapses in the state of FIG. 7B, the operation cam main body 271 continues the constant rotation by the elevating driving source 210. At this time, the locking step 237 of the operation head 235 is caught by the locking protrusion 279 in a predetermined section to suppress the rise of the operation head 235. In this section, while the pressing force between the pressure cooker 110 and the pressure lid 120 is partially released, steam generated in the puffing process and trapped in the pressure cooker 110 is discharged to the outside.

7D illustrates a process in which the operating rod 220 is released from the locking protrusion 279. When the operation cam body 271 is out of the predetermined section by the continuous rotation, the pressing portion 273 is in contact with the lever body 277 to rotate the lever body 277. Accordingly, while the locking projection 279 and the locking jaw 237 is released, the operation rod 220 is raised to the position shown in FIG. 7A by the elastic bias of the first elastic member 221.

By configuring the operation cam 270, the operation rod 220 and the trigger lever 275 as described above, it is possible to compact the overall configuration by performing the compression, steam discharge, opening operation. In addition, by changing the type of puffing grain or the puffing condition in all sections except the compression firm position, by rotating at a constant speed at a predetermined rotational speed without shifting the operation cam 270, a speed delay due to the grain can be minimized.
