In a state where the seating surface 112 and the inclined surface 113 are in contact with the upper freezing container outlet 63, respectively, the solenoid case 111 is fixed to the front frame 27 in the front-rear direction so as to be inserted into the two hubs of the solenoid case 111, respectively. The screw in the portion 116 is simply aligned with the target position of the front frame 27. When the solenoid case 111 is fixed inside the case 1, the positioning protrusion 169 of the case cover 66 is inserted into the positioning groove portion 170* of the solenoid case 111 from above and is located at the positioning protrusion 169 and When the positioning groove portions 170 are engaged with each other, the rear end portion of the cover 166 is pushed downward. Then, the left side plate of the solenoid case ηι is elastically deformed based on the pressing of the claw portion 167 of the left side plate of the case cover 166. The right side plate of the solenoid case 111 is pressed based on the claw portion 167 of the right side plate of the case cover 166. The elastic deformation 'engages the claw portions of the two claw portions 167 of the cover 166 in the engagement portion 168 of the solenoid case 111. In the engaged state of the positioning projections 169 and the positioning groove portions 170, the cover 166 is a phase -32-

1351503 The solenoid case 111 is positioned in the front-rear direction, and the respective claw portions of the case claw portion 167 and the engagement portion 1 of the solenoid case ill are inside the case 1 as shown in FIG. Substrate box 171. The substrate case 171 is provided with a control circuit on which a control substrate is housed. This control circuit is a microcomputer and has: CPU, ROM and RAM. The switches of the control circuit 7 and the push button switch 94 are electrically wired, and the output signal from the door switch 70 is controlled to determine whether the sliding door 36 is set or not, and the operation button 86 is determined based on the output signal from the push button switch 94. The control circuit is connected with a relay circuit for energizing/de-energizing the relay coil according to the respective states of the corresponding door switch 70 and the push button switch 94, performing a relay closing operation, and performing ON/OFF control of the solenoid coil 1 29. It is a flowchart for explaining the ROM previously recorded in the control circuit. Hereinafter, the processing contents according to the control program of Fig. 17 will be described. The CPU of the control circuit determines whether the door switch 70 is ON after the power is turned on. For example, in a state where the position of the sliding door 36 is lowered, it is determined in step s1 that the door switch 70 is S2 and the timer T1 is reset to "0". This timer T1 is an elapsed time when the door 36 has moved to the closed position as a reference. The first time interval is determined by a certain time interval, and a timed interrupt processing is added to the predetermined unit. The CPU is resetting the timer T1 in step S2, [the two 68 of the cover 166 are simply aligned above the chamber 17 ^ board, control base; body composition, the door switch J circuit is based on f in the off position to determine whether there is a control circuit for controlling the opening of the switch of the electrical switch of the switch, the operation of the control circuit in step S1 To turn off the ON, measure the following slip in the step § · At the CPU pre-start at the start of each turn to step -33 - 1351503 " S3 'determine whether the door switch 70 is OFF. For example, when the user does not operate the operation button 86 to manually operate the slide door 36 from the closed position to the front side, the door switch 70 is switched from the ON state to the OFF state. At this time, the CPU judges in step S3 that the door switch 70 is 0FF and returns to step si. In this state, when the sliding door 36 is operated to the closed position, it is judged that the door switch 7 is already ON. In step S2, the timer T1 is reset to "〇". In a state where the slide door 36 has been operated to the closed position, the CPU judges that the door switch 70 is not OFF at -φ step S3, and judges at step S4 that the switch 94 is ON. For example, when the sliding door 36 is operated to the closed position, when the user presses the operation button 66, it is judged that the button switch 94 is ON in step S4. The timer T1 is added in step S5. The result is compared to the action inhibit time TW (eg 1 _ 5 seconds). The operation prohibition time Tw is previously recorded in the control circuit R〇M, and when the CPU determines in step S5 that the addition result of the timer T1 has not reached the operation prohibition time T w , the CPU returns to step S 3 . That is, based on the user's pressing of the operation button 86, when the sliding door 36 is pressed and returned to the closed position, J, the addition result of the timer τ 1 does not reach the action prohibition time T w . The button switch 94 is ON. At this time, the on of the push button switch 94 is invalid, and the door operating device 1 1 〇 does not operate. When the CPU determines in step S5 that the addition result of the timer τΐ has reached the operation prohibition time Tw, the CPU 开始 turns on the relay coil 129' in step S6, and the timer T3 is reset to "〇" in step S7. . This timer T3 is an elapsed time when the measurement of the solenoid line 圏129 is ON, and C Ρ ϋ is determined in a predetermined time -34-

1351503 Interrupt timer processing is started, and the predetermined unit 加 is added to each timing interrupt processing. When the CPU resets the timer T3 in step S7, it is determined whether or not the door switch 70 is OFF in step S8. For example, when the sliding door 36 does not act to exceed the excessive pressing force of the feeder 154, the sliding door 36 is moved forward from the closed position based on the state in which the driving of the screw line 129 is started. Thus, the CPU determines that the door switch 70 is OFF in step S8 and the transfer step is performed. When the CPU determines in step S8 that the door switch 70 is not OFF, the step S12 compares the addition result of the timer T3 with the pre-recorded ROM standby limit time Tf. . The standby limit time Tf is based on the continuous energization of the line 圏129 to prevent abnormal temperature rise. When the CPU determines in step S12 that the addition result of the timer T3 has not reached the machine limit time Tf, the CPU returns to step S8. . That is, when the sliding door 3 6 uses an excessive load exceeding the pressing force of the pusher 154, the solenoid coil 129 is started to be driven, and the sliding door 36 does not move forward from the closed position, and the solenoid coil 1 29 The standby limit time Tf is energized for the limit. Before the standby limit time Tf elapses, when a large load is removed from the sliding door 36, the sliding door 36 is pushed forward by the pusher 154 from the closed position. At this time, when C P U is judged to be OFF in step s8, the process proceeds to step S9. When the CPU moves from the closed position to the front even if the slide door 36 moves forward from the closed position Tf, the CPU shifts from step S12 to step S11 and stops the drive coil coil 129 from being pushed and pushed. The snails are waiting to be made to go through 70 no -35-

1351503 When the CPU shifts to step S9, the timer T2 is reset to the timer. Τ2 is the measurement when the door switch 70 is OFF. The reference is between the CPUs. The CPU starts timing at a predetermined time interval and starts each timer interrupt processing. When the pre-determination CPU resets the timer T2 in step S9, the addition result of the step T2 is compared with the energization time recorded in advance at R〇M. When the energization time Te is equivalent to the driving of the solenoid coil 129 required to move the column forward position from the retracted position, it is determined in step S10 that the addition result of the timer T2 has reached Te, and the step S11 is shifted, and based on The relay coil is OFF, solenoid coil 129. When the driving of the solenoid coil 129 is stopped, the pushing of the pusher 1 54 causes the sliding door 36 to be biased from the closed position toward the front. The user can buckle the finger to the handle portion 66 of the sliding door 36, toward the sliding door 36. And can be pulled out to the open position. Fig. 18 shows the ON/OFF of the push button switch 94, the ON/OFF of the solenoid switch | ON/OFF 'door switch 70, and the slide door 36 open, and the slide operation door 6 is operated to the closed position. When the push button switch 94 is pressed, the ON of the solenoid coil 129 and the push button switch 94 is delayed by the ON time of the switch 70 from the ON of the solenoid coil 129, and the slide door 36 is moved forward from the closed position. mobile. When the slide door 36 is open, when the operation button 8 6 is operated, the effective "0" is not applied to the detection area of the push button switch 94. The unit 値S 1 0 of the elapsed time interrupt processing is performed with the plug 134 facing downward, and the CPU energization time stops driving based on the movement of the front side, and the closing time of the front side operation ring 129 is turned ON, and the door is detected. Go out and magnetically from the magnetic buckle. This -36- 1351503

Since the push button switch 94 does not become 〇N, the solenoid coil 丨29 does not turn ON, and the door operating device 110 does not operate. When the pressing operation of the sliding door 36 is performed in the operating state of the operation button 86, the on/off switch 7 is synchronized from the OFF state to the ON state to detect the on button of the button switch 94. The addition result does not reach the operation prohibition time Tw', so the solenoid coil 129 does not turn ON, and the door operating device 11 does not operate. According to the addition result of the timer T1, the operation button 86 is operated before the operation prohibition time Tw is reached, and even if the button switch 94 is already ON, the solenoid coil 129 is not turned ON, and the door operating device 11 does not actuate the 'spiral line'. In the state where the addition result of the timer T1 reaches the operation prohibition time Tw, the operation button 605 is turned ON. According to the above embodiment 1, the following effects are achieved. Since the mechanical position of the magnetic clasp 90 is changed between the ineffective position and the effective position according to the presence or absence of the operation button 86, and the mechanical position of the magnetic clasp 90 is detected in a non-contact manner according to the effective position 94, the door operating device is driven. 1 1 〇, therefore, no electrical wiring is required between the sliding door 36 and the case 1. Therefore, there is no need to cover the wiring so that the user's hand and water do not come into contact with the wiring, and since it is not necessary to perform wiring, the special processing for changing the wiring distance is required, so that the overall structure is simple. The support shaft 87 is formed on the bottom plate of the mechanism chamber 68 of the upper cover 42, and since the mechanism chamber cover 95 is supported from below by the support shaft 87, the urethane foam 39 is filled in the door casing 38. When the bottom plate of the mechanism chamber 68 is swelled upward, the mechanism chamber cover 95 can be lifted in the same direction by the support shaft 87. Therefore, the height dimension of the mechanism chamber 68 is prevented from being disturbed by the upper surface of the magnet stage 88 and the mechanism chamber cover 95 due to the fact that the 塡 塡 塡 - - - - 小于 小于 39 39 39 39 The resulting action is poor.

The left arm 71, the right arm 73, the return spring 77, the magnet stage 88, and the magnetic lock 90 are housed in the common mechanism chamber 68, respectively, and the upper surface of the mechanism chamber 68 is covered by the detachable mechanism chamber cover 95. Therefore, since the left arm 71 to the magnetic clasp 90 can be separately inspected and maintained at a time by removing the mechanism chamber cover 95 from the mechanism chamber 68, the maintenance inspection is performed in such a manner that the left arm 71 to the magnetic clasp 90 are dispersedly arranged. It's easy to change. A part of the movement locus ML when the magnetic clasp 90 is moved from the ineffective position to the effective position in the rear of the door rear panel 41 of the sliding door 36 protrudes rearward from the mounting surface 44. Therefore, since the magnetic clasp 90 is close to the push button switch 94, the push button switch 94 can be surely turned/OFF by the magnetic clasp 90. The ineffective position facing the chamfered portion 93 and the push button switch 94 and the effective position of the long side portion 91 and the push button switch 94 are moved toward each other in the circumferential direction to operate the magnetic clasp 90. Therefore, due to the ineffective position of the magnetic clasp 90, The magnetic force acting on the push button switch 94 from the magnetic clasp 90 is weakened, and at the effective position of the magnetic clasp 90, the magnetic force acting on the push button switch 94 from the magnetic clasp 90 becomes strong, so from this point of view, the magnetic clasp 90 can be used. The button switch 94 is indeed turned ON/OFF. Further, since the orientation of the chamfered portion 93 and the outline shape of the rectangle can be distinguished from the posture of the magnetic clasp 90 when the magnetic clasp 90 is attached to the magnet stage 88, the magnetic clasp 90 can be prevented from being attached to the magnet stage 88 in an erroneous posture. When the support shaft 87 of the magnet stage 88 is viewed from the up-down direction, the cam groove 89 and the magnetic clasp 90 are not overlapped with each other, so that the two are facing the horizontal -38 - 1351503, and the left side is buckled. This production is 71 points and 71 valences are arranged on the magnet stage 88 separately from each other in the direction of the time. Therefore, since it is not necessary to prevent the pin 81 in the cam groove 89 from interfering with the magnetic clasp 90, the lower side of the magnetic clasp 90 is lifted from the upper surface of the magnet stage 88, so that the vertical dimension of the sliding door 36 can be prevented from becoming larger. .

The left axis 72 of the left arm 71 and the right axis 74 of the right arm 73 are disposed on a common straight line extending in the right direction, and the distance between the left axis 72 and the middle axis 75 is set to be opposite to the right axis 74 and the center axis 75. The distance between the two is the same. Therefore, based on the push operation button 86, since the center shaft 75 moves from the front straight line, the operation button 86 does not tilt when pushed in. When the push operation operation button 86 is constituted by a cushioning material such as rubber expansion, the magnetic 90 is stopped at the effective position, and the stopper 79 of the position of the operation button 86 is restricted, so that the impact sound when the operation button 86 is pushed in is prevented. . Further, when the operating force is removed from the operation button 86, the position of each arm of the right arm 73 of the left arm 71 is restricted by the stopper 79, and the magnetic lock 90 is stopped at the ineffective position. Therefore, since the impact sound is prevented from being removed from the operation button 86, the overall quietness is improved. Further, the stopper 79 is formed in a circular shape so that the impact position of the stopper 79 of the operation knob 86 with respect to the impact position of the stopper 79 for the left arm and the stopper 79 of the right arm 73 are not in the front-rear direction. Make a difference. Therefore, since the operation knob 86, the left arm, and the right arm 73 can respectively restrict the position by the common stopper 7, the productivity is improved. When the user mistakenly pushes the operation button 86 into operation to return the slide door 36 to the closed position, the operation button 86 and the slide door 36 reach the closed position, and the operation button 86 is detected to operate to the operation position. At this time, since the measurement result of the timing -39-1351503 T1 does not reach the operation prohibition time Tw, the drive power is not applied to the solenoid coil 129. Therefore, since the door operating device 11 is not actuated, it is possible to prevent the thrust force from being applied to the driver 154 from the door operating device 11 without paying attention to the user.

When the driving power is applied to the solenoid coil 129, it is judged whether or not the sliding door 36 is held in the closed position. When it is judged that the sliding door 36 is not held to the closed position, the resetting timer T2 determines that the measurement result of the timer T2 reaches the energizing time. When Te is used, the driving power of the solenoid coil 129 is cut off. Therefore, based on the excessive load on the sliding door 36, when the sliding door 36 does not move forward from the closed position, since the solenoid coil 129 is continuously energized, the user simply removes the excessive load, and the sliding door 36 is closed. The position moves forward. Therefore, since the user does not need to operate the operation button 86 cumbersomely, the usability is improved. In the first embodiment described above, when the sliding door 36 is operated from the rear to the rear, the sliding door 36 can be pulled to the closed position by mechanical force using the suction mechanism. At this time, 'the movable rails of the two second movable rails 35 of the sliding door 36 are provided with pins'. When the sliding door 36 is operated from the rear to the rear, the pins of the two pins are engaged with the pull-in members, and are operated based on the spring force of the spring. Pull the sliding door 36 into the closed position by pulling in the member. In the above-described first embodiment, a square magnetic fastener may be used instead of the rectangular magnetic fastener 90. In this configuration, it is preferable to use a configuration in which a wrong shape and a rectangular shape are attached to each other. Therefore, it is preferable to form an inclined surface at a corner portion or to prevent erroneous mounting during mounting. Further, in this configuration, the chamfered portion can be formed in the square-shaped magnetic clasp, and the magnetic clasp in the shape of the square -401-35353 faces the ineffective position of the push button switch 94 at the chamfered portion and the side of the square is facing the button. The effective positions of the switches 94 are moved to each other in the circumferential direction. In the above embodiment 1, a motor can also be used as the drive source of the door operating device 110. In the first embodiment described above, the movement locus ML of the magnetic clasp 90 can be protruded further rearward than the mounting surface 44 of the door rear panel 41.
