BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for pouring frozen desserts such as ice cream and yogurt.

[0002]

2. Description of the Related Art Conventionally, an ice cream dispenser as shown in FIG. 7 is known. This is because a pouring cylinder 103 in which a piston 102 is slidably fitted is provided vertically on the back side of a door 101 of a freezer 100, while a pouring path is provided inside the door 101 on the outer surface. A valve body 104 that opens and closes the pouring path is fitted with a pouring portion 105 that is vertically movable by operating a cock 110, and a connecting pipe 106 protruding from the pouring portion 105 is attached.
Is connected to the outlet C of the ice cream pack B housed on the upper surface side of the piston 102 in the dispensing cylinder 103.

A pressing switch 107 is provided on the upper surface of the door 101, while a pressing plate 108 capable of pressing the switch 107 is screwed to the upper surface of the valve body 104. Then, when the valve body 104 is raised and the pouring path is opened, the pressing plate 108 is accompanied with it.
Rises and the switch 107 is turned on, and the working fluid x is supplied to the lower surface side of the piston 102 by the pump 109 and rises to compress the pack B, whereby the pouring in the pouring portion 105 from the connecting pipe 106 is performed. Ice cream is poured out through the exit route.

[0004]

Here, the pressing plate 108 is used.
Is attached to the upper surface of the valve element 104 in a protruding state, and therefore, if another object is accidentally hit against the pressing plate 108, the pressing plate 108 will be vertically moved together with the valve element 104 due to the clearance at the connecting portion with the cock 110. When rotating around the axis or loosening the screw, the pressing plate 108 causes the valve body 1 to move.
There is a risk of turning with respect to 04. Then, the pressing plate 108 does not correspond to the position directly below the switch 107, and the valve body 10 should be poured to dispense ice cream.
There was a possibility that the switch 107 could not be pressed even if 4 was raised, that is, the pump 109 could not be driven.

Further, if ice cream remains attached to the pouring path in the pouring portion 105, it is not preferable for hygiene, so it is necessary to clean it appropriately. In that case, the pouring part 10
5 will be removed from the door 101 for cleaning, but if the pressing plate 108 is bumped against another object during cleaning or carrying it to a water place, it may be displaced likewise, and it is poured out while being overlooked. When the part 105 is reattached, there is a problem that the switch 107 cannot be pressed normally when the valve body 104 is raised. The present invention has been completed based on the above circumstances, and an object thereof is to ensure that an operating member attached to a valve body can be reliably advanced and retracted at a regular position corresponding to a switch.

[0006]

As a means for achieving the above object, the invention of claim 1 provides a pouring path inside the outer wall of a cold storage room equipped with a device for discharging frozen desserts. Is attached to the discharge device, and the valve body attached to the discharge part so as to be able to move back and forth opens and closes the discharge path. A switch for controlling is provided, and the valve body,
A guide provided with an operating member that comes in and out of contact with the switch and is fitted to the operating member on the outer wall of the cooling storage chamber to move and guide the operating member in a direction of coming into contact with and separating from the switch.

According to a second aspect of the present invention, in the first aspect, the outer wall of the cooling storage chamber is engaged with the operating member when the spout is attached to the outer wall to guide the operating member. It is characterized in that a guide member for guiding it so as to fit into a road is provided.

[0007]

<Operation and Effect of the Invention><Invention of Claim 1> The operating member is brought into contact with and separated from the switch along the guide path at a position corresponding to the switch. The switch can be reliably turned on and off in conjunction with the advance and retreat of the valve body. <Invention of Claim 2> When the pouring portion is removed for cleaning or the like and is reattached, even if the operation member is displaced, the operation member is guided along with the operation of attaching the pouring portion. The member is fitted into the guide path while its posture is corrected.
