  On the other hand, the upper end of the plunger 16 is formed with a threaded portion 16A whose outer surface is threaded, and a plunger cap 45 is coupled to the threaded portion 16A by screwing. One end of a wire 46 is supported on the plunger cap 45, and the other end of the wire 46 is connected to a foot pedal 47 disposed in the lower portion of the main body 1 through the main body 1. The wire 46 is surrounded by a tube 46 </ b> A composed of a flexible material on the outer periphery, and is movable within the tube 46 </ b> A fixed in the main body 1.

  A coil spring (biasing means) 48 is interposed between the plunger cap 45 and the top portion 1A of the main body 1 (a mounting plate 50 provided inside), and always urges the plunger 16 downward. .

  As shown in FIG. 4, the foot pedal 47 is positioned behind the step-down surface 47 </ b> A formed on the upper surface of the front portion by a predetermined dimension and is bent at a substantially right angle upward. 47B is formed, and a fixing hole 47C for winding and fixing the wire 46 is formed in the wire attachment piece 47B. The spring member 51 is attached to the rear of the wire attachment piece 47B. One end of the spring member 51 is fixed to the bottom surface of the main body 1 via the mounting plate 52, and the other end is attached to the foot pedal 47. Energize in the direction.

  Thereby, the plunger 16 is normally held at the lowered position that closes the communicating portion of the extraction passage 15 and the extraction passage 11 by the action of the coil spring 48, and stops the extraction of the frozen dessert. On the other hand, when the stepping surface 47A of the foot pedal 47 is depressed, the plunger cap 45 and the plunger 16 are moved up against the biasing force of the coil spring 48 by the wire 46, and the communication portion between the extraction passage 15 and the extraction passage 11 is blocked. Is released and the extraction passage 15 is opened, whereby the frozen dessert is extracted to the outside.

  Further, when the leg is released from the stepping surface 47A of the foot pedal 47, the stepping surface 47A and the wire 46 are raised by the action of the spring member 51 and the coil spring 48, and the take-out passage 15 is closed as described above.

  Here, the mounting plate 52 used for mounting the spring member 51 of the foot pedal 47 has a substantially U-shaped cross section that opens downward, and the front wall 52A is more than the rear wall to which the spring member 51 is mounted. Is formed to extend long downward. The front wall 52A has a substantially L-shaped through hole 53 through which the foot pedal 47 is inserted.

  That is, the mounting plate 52 in which the through hole 53 is formed constitutes a holding mechanism for the foot pedal 47. The through hole 53 includes an upper and lower through hole 53A extending up and down and the upper and lower through hole 53A. In this embodiment, the holding through-hole 53B is formed to extend from the lower edge (lower part) in the horizontal direction, to the left from the front of the device SM.

  Therefore, when the foot pedal 47 is not operated, the foot pedal 47 is held at the upper edge in the upper and lower through holes 53 </ b> A by the urging force of the spring member 51 and the coil spring 48. In a state where the stepped surface 47A of the foot pedal 47 is depressed, the foot pedal 47 is moved in the horizontal direction (in this case, the left side, holding through hole 53B) along the lower edge of the upper and lower through holes 53A. The foot pedal 47 is locked to the upper edge of the holding through-hole 53B against the urging force of the spring member 51 and the coil spring 48, and the foot pedal 47 is held in a depressed state.

The upper wall 30 </ b> A of the holder 30 abuts on the lower edge of the protrusion 45 </ b> A of each plunger cap 45 whose upper surface is in the raised position, and the front end abuts on the front surface of the main body 1. The lower wall 30 </ b> B contacts the upper surface of the freezer door 14 where the take-out passage 15 is formed at the lower surface and the front surface of the lower wall 30 </ b> B where the front end contacts the main body 1. A plurality of notches 31A and 31B for bypassing each plunger 16 are formed in the upper wall 30A and the lower wall 30B, respectively.

  With this configuration, when communicating between the respective cooling cylinders 8 and the respective extraction passages 15 at the time of cleaning or the like as in the above-described embodiment, first, the foot pedals 47 are stepped down sequentially from the end, The wire 46 fixed to 47 raises each plunger 16 against the urging force of the coil spring 48 and sets it to the raised position. As a result, the blocking of the communication portion between the extraction passage 15 and the extraction passage 11 is released, and the extraction passage 15 is opened.

  In this state, each plunger 16 that is in the raised position is similarly in the raised position for each plunger cap 45 attached to the upper end, and therefore, between the protrusion 45A at the bottom of each plunger cap 45 and the upper surface of the freezer door 14. The holder 30 is inserted in the above. By sequentially depressing the foot pedal 47, the holders 30 are inserted in the same way for the plungers 16 as well.

  Thereby, the protrusion 45A of each plunger cap 45 holds the raised position where the plunger cap 45 and the plunger 16 are pulled up against the biasing force of the coil spring 48 by the holder 30. Therefore, in this state, the plunger cap 45 and the plunger 16 are held in the raised position against the urging force of the coil spring 48 and the spring member 51 even if the leg for operating any of the foot pedals 47 is released, and the foot pedal is continuously operated. The open state of the extraction passage 15 is maintained without stepping on 47. As a result, it is possible to realize continuous work of taking out mixes, frozen desserts, washing water, etc., and the operator does not have to keep stepping on the plurality of foot pedals 47, thereby improving workability. it can.

  In particular, since one worker can step down a plurality of foot pedals 47 that cannot be stepped on at the same time, the time required for cleaning work can be shortened, and the work efficiency can be further improved. Improvements can be made.

  In the state where the foot is placed on the stepping surface 47A of the foot pedal 47, the holding state of the plunger 16 is released by removing the holding tool 30, and the foot 16 is continuously released by releasing the leg. The communication between the cooling cylinder 8 and the take-out passage 15 can be stopped.
