In this way, it is connected to the operation plate 33.

  As shown in FIG. 3, an F door opening switch 48 and a V door opening switch 49 are connected to the control circuit 38. The F door opening switch 48 is composed of a Hall IC which is housed inside the intermediate heat insulating partition wall 8 so as to be located behind the permanent magnet of the F door button 17. It is turned off without receiving a magnetic force, and is turned on in response to the magnetic force from the permanent magnet based on the F door button 17 being operated from the initial position to the pushing position. The V door opening switch 49 is composed of a Hall IC which is housed in the lower heat insulating partition wall 12 so as to be located behind the permanent magnet of the V door button 22. It is turned off without receiving a magnetic force, and is turned on in response to the magnetic force from the permanent magnet based on the operation of the V door button 22 from the initial position to the pushing position.

  A control program is recorded in the ROM of the control circuit 38, and the CPU of the control circuit 38 operates each of the F slide door 14 and the V slide door 19 based on rotating the door operation motor 31 according to the control program. . Hereinafter, details of the door operation processing of the CPU of the control circuit 38 will be described based on the flowchart of FIG.

  In step S1, the CPU determines whether or not the F door opening switch 48 is turned on. In step S6, the CPU determines whether or not the V door opening switch 49 is turned on. In a state where each of the F door opening switch 48 and the V door opening switch 49 is turned off, the operation plate 33 is held in the neutral position as shown in FIG. At the neutral position of the operation plate 33, the F pusher 46 and the V pusher 47 are held at their initial positions. When the F slide door 14 is operated in the closed state, the F pusher 46 is at the lower end of the F slide door 14. The V pusher 47 faces the upper end portion of the V slide door 19 from behind via a gap.

  When the CPU determines that the F door opening switch 48 is turned on in step S1 of FIG. 8, the CPU outputs a normal rotation command to the motor drive circuit 37 in step S2. The motor drive circuit 37 outputs a drive signal Dc for forward rotation to the door operation motor 31 when detecting a forward rotation command from the CPU. This drive signal Dc is for rotating the rotation shaft 32 of the door operation motor 31 in the direction of the arrow in FIG. 3 by a predetermined unit angle θ, and the rotation shaft 32 of the door operation motor 31 is based on the drive signal Dc. When rotated by the unit angle θ in the direction of the arrow, as shown in FIG. 6, the F rod 39 moves forward based on the rotation of the operation plate 33 from the neutral position to the F door operation position, and the F pusher 46 is moved. It moves from the initial position to the forward advance position via the F rod 39. At the same time, the V rod 42 moves backward opposite to the F rod 39, and the V pusher 47 moves from the initial position to the backward retracted position via the V rod 42. That is, when the user operates the F door button 17 from the initial position to the pushed position while the F slide door 14 is closed, the F pusher 46 moves from the initial position to the forward position, and the F slide door 14 is directed from the rear to the front. And moving forward from the closed state based on the pressing. Since the V pusher 48 moves to the retracted position when the F pusher 46 moves forward, the V pusher 47 moves away from the V slide door 19 even when the V slide door 19 is operated in the closed state. 19 is not operated forward from the closed state.

  When the CPU outputs a normal rotation command to the motor drive circuit 37 in step S2 of FIG. 8, the CPU resets the timer T of the RAM to “0” in step S3. The timer T is measured based on the CPU starting a timer interrupt process different from the door operation process at a constant time interval, and adding a constant unit value every time the timer interrupt process is started. When the timer T is reset in step S3, the process proceeds to step S4, and the addition result of the timer T is compared with the set time. This set time is recorded in advance in the ROM of the control circuit 38, and is a margin for the time required for the F pusher 46 to move from the initial position to the forward position and for the V pusher 47 to move from the initial position to the backward position. It is set from adding.

  When the CPU determines that “the addition result of the timer T = the set time” in step S4, the CPU outputs a reverse rotation command to the motor drive circuit 37 in step S5. The motor drive circuit 37 outputs a drive signal Dr for reverse rotation to the door operation motor 31 when detecting a reverse rotation command from the CPU. This drive signal Dr is for rotating the rotation shaft 32 of the door operation motor 31 by a unit angle θ in the opposite arrow direction opposite to the arrow direction in FIG. 3, and the rotation shaft 32 of the door operation motor 31 is driven by the drive signal Dr. 6, the operation plate 33 returns from the F door operation position in FIG. 6 to the neutral position in FIG. 3, and the F pusher 46 is moved from the forward position to the initial position via the F rod 39. The V pusher 47 is operated from the retracted position to the initial position via the V rod 42.

  When the CPU determines that the V door opening switch 49 is turned on in step S6 of FIG. 8, the CPU outputs a reverse rotation command to the motor drive circuit 37 in step S7. When the motor drive circuit 37 detects a reverse rotation command from the CPU, it outputs a drive signal Dr to the door operation motor 31 and rotates the rotation shaft 32 of the door operation motor 31 in the counter-arrow direction by a unit angle θ. In this case, as shown in FIG. 7, the V rod 42 moves forward based on the rotation of the operation plate 33 from the neutral position to the V door operation position, and the V pusher 47 passes through the V rod 42. Move from the initial position to the forward advance position. At the same time, the F rod 39 moves backward, opposite to the V rod 42, and the F pusher 46 moves from the initial position to the backward retracted position via the F rod 39. That is, when the user operates the V door button 22 from the initial position to the pushed position while the V slide door 19 is closed, the V pusher 47 moves from the initial position to the forward position, and the V slide door 19 is directed from the rear to the front. And moving forward from the closed state based on the pressing. Since the F pusher 46 moves to the retracted position when the V pusher 47 moves forward, the F pusher 46 moves away from the F slide door 14 even when the F slide door 14 is operated in the closed state. 14 is not operated forward from the closed state.

  When the CPU outputs a reverse rotation command to the motor drive circuit 37 in step S7 in FIG. 8, the timer T of the RAM is reset to “0” in step S8, and the addition result of the timer T is compared with the set time in step S9. When it is determined that “the addition result of the timer T = the set time”, the process proceeds to step S 10, and a normal rotation command is output to the motor drive circuit 37. The motor drive circuit 37 outputs a drive signal Dc to the door operation motor 31 when it detects a forward rotation command from the CPU. In this case, the operation plate 33 is moved from the V door operation position in FIG. 7 to the neutral position in FIG. 3 based on the rotation shaft 32 of the door operation motor 31 rotating in the direction of the arrow by the unit angle θ based on the drive signal Dc. Returning, the V pusher 47 is operated from the forward position to the initial position via the V rod 42, and the F pusher 46 is operated from the reverse position to the initial position via the F rod 39.

According to the said Example 1, there exists the following effect.
The first pusher member 50 and the second pusher member 60 are selectively moved to the forward positions based on the rotation operation of the operation plate 33 by the door operation motor 31, and the F slide door of the freezer compartment 13 is operated. 14 and the V slide door 19 of the vegetable compartment 18 were alternatively pressed forward from the closed state. For this reason, there is no need to store a dedicated door operating device in each of the freezer compartment 13 and the vegetable compartment 18, so that the storage space for the food in the freezer compartment 13 and the vegetable compartment 18 can be kept small. Each of the F slide door 14 and the V slide door 19 can be operated by a common door operation device 30. Moreover, each of the first pusher member 50 and the second pusher member 60 is advanced and retracted based on controlling the rotation direction of the rotation shaft 32 of the door operation motor 31. For this reason, each of the spring for retracting the first pusher member 50 from the advanced position and the spring for retracting the second pusher member 60 from the advanced position are not required, and the mechanical configuration is simplified.

  An F door button 17 for operating the F slide door 14 is attached to the F slide door 14, and a V door button 22 for operating the V slide door 19 is attached to the V slide door 19. Therefore, the user can operate the F door button 17 without hesitation when operating the F slide door 14, and can operate the V door button 22 without hesitation when operating the V slide door 19. Each of the first pusher member 50 and the second pusher member 60 was slidably connected to the operation plate 33. For this reason, each of the first pusher member 50 and the second pusher member 60 slides with respect to the operation plate 33 based on the rotation of the operation plate 33 and has a constant interval parallel to each other. Since it moves linearly in the front-rear direction while maintaining it, the rotational motion of the operation plate 33 and the twist between the linear motions of the first pusher member 50 are eliminated, and the rotational motion of the operation plate 33 and the second pusher member 60 are eliminated. The twist between the linear motions is eliminated. Therefore, it is possible to prevent the first pusher member 50 and the second pusher member 60 from malfunctioning.

In the first embodiment, a push switch may be used as each of the F door opening switch 48 and the V door opening switch 49.
In the first embodiment, a servo motor may be used as the door operation motor 31.
