DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a pouring section of a frozen dessert pouring device.

[0002]

2. Description of the Related Art As a conventional ice cream dispenser, a cooling cylinder is provided with a discharging cylinder in which a pack of ice cream is stored, and the cylinder is driven to compress the pack to discharge ice cream. What discharge | ejects from the injection | pouring part provided in the outer wall of the cooling storage room is known. In this pouring section, as shown in FIG.
A vertical pouring passage 101 in which a valve body 100 which is raised and lowered by a lever operation or the like is fitted is provided, and a connecting pipe 102 provided in a laterally communicating side with the side protrudes into the refrigerator to be connected to a pack outlet. A cap 103 having a thick and shallow dish shape is screwed to the lower end of the pouring passage 101, and a spout 104 is formed on the bottom surface of the cap 103.

When pouring ice cream A, the pack is compressed by a pouring cylinder,
When the valve body 100 is raised to a position higher than the communication port 105 as shown in FIG. 7A, the ice cream A discharged from the pack passes from the connection pipe 102 through the communication port 105 to the discharge passage 101. It is pushed downward and is poured out of the spout 104 into the cup. When the proper amount is poured out, the compression of the pack is stopped, and as shown in FIG.
The valve body 100 is lowered to a position where the communication port 105 and the spout 104 are closed, whereby the pouring is completed.

[0004]

However, since the ice cream A to be poured has an appropriate stickiness, even if the valve element 100 closes the upper surface of the spout 104, a part of the ice cream A is removed. The inner peripheral surface of the spout 104 is adhered to the inner peripheral surface of the spout 104, so that the so-called poor cutting is obtained (see FIG. 7B). This cut is made in spout 10
4 is considered to be worse as the volume inside increases, so that it is effective to make the bottom plate of the cap 103 thinner in order to reduce the volume inside the spout 104 in order to improve the cutting performance. However, in the case of hard ice having an appropriate hardness, if the bottom plate of the cap 103 is thin, the cap 103 may be broken at the time of pouring, and cannot be easily coped with. The present invention has been completed based on the above circumstances, and an object of the present invention is to allow a frozen dessert to be smoothly separated from a spout at the end of pouring.

[0005]

As a means for achieving the above object, according to the first aspect of the present invention, there is provided a dispensing part structure of a frozen dessert dispensing apparatus, wherein a cooling cylinder having a cylinder for dispensing the dessert therein is provided. A pouring portion is provided on an outer wall of the storage chamber, and a vertical pouring passage in which a valve body is slidably fitted and a pouring port is provided at a lower end is formed in the pouring portion. A connecting pipe communicating with a side surface of the pouring passage and projecting into the cooling storage chamber is connected to the discharge side of the pouring cylinder, and the valve body communicates with the connecting pipe in the pouring passage. In this case, the dispensing of the frozen dessert is performed by moving the valve body upward, and the pouring is terminated by lowering the valve body to a position where the communication port and the spout are closed. On the lower surface, when this valve element is lowered to the lowered position, It has a feature where the entrant projections are provided.

According to a second aspect of the present invention, in the first aspect, a lower surface of the valve body and a surface on which the spout is formed are formed in a conical shape with a downwardly pointed cone. It is characterized in that the protrusion is provided at the tip. The invention according to claim 3 is the one according to claim 1 or 2, wherein a female screw is formed at a lower end of the pouring passage,
A cap having a cylindrical shape having an upper surface plate and having an external thread which can be screwed to the female screw formed on the outer periphery is provided. The cap is characterized in that the spout is opened in the upper surface plate.

A fourth aspect of the present invention is characterized in that, in the third aspect, a diameter of a male screw of the cap is set smaller than a diameter of a female screw of the pouring passage. According to a fifth aspect of the present invention, in the third or fourth aspect, an upper portion of the cap on which the external thread is formed can be fitted approximately tightly inside an internal thread of the spout passage. It is characterized by the provision of a simple circumferential guide.

[0008]

<Invention of claim 1> When the valve body is lowered to the lowered position in order to stop the dispensing of the frozen dessert, the projection on the lower surface of the valve body protrudes into the spout and the inside of the spout. Push out the frozen dessert that you want to keep. In this method, even if the mouth of the spout is thick to ensure the strength, the spout can be surely extruded, and it is particularly suitable to be applied to an apparatus for pouring a frozen dessert having relatively high hardness. <Invention of claim 2> By making the lower surface of the valve body conical,
The elevation required to fully open the communication port is low,
That is, the up / down stroke of the valve element can be reduced. <Invention of claim 3> Since the spout is formed in the cap which is attached to and detached from the spout passage, the spout can be easily cleaned.

<Invention of Claim 4> When the cap is removed and washed, it is desirable to wash it with high-temperature water in order to prevent the propagation of various bacteria, and the cap is likely to thermally expand. On the other hand, the spout is attached to the outer wall of the cooling storage room and cooled, and rather is in a contracted state.When the cap is screwed again after washing, the cap is expanded due to the expansion of the male screw side. It may not be possible to screw in. In this regard, in the present invention, since the diameter of the male screw on the cap side is set to be smaller than the diameter of the female screw in the pouring passage, even if the cap thermally expands, it is screwed to the female screw on the other side. be able to. <Invention of claim 5> When the male screw of the cap is attached to the female screw of the spouting passage, the guide portion is first fitted almost tightly inside the female screw and is centered. The meshing can be performed smoothly, so that the cap can be more easily attached.

Equipped.

Next, the structure of the pouring section 31 and the arrangement portion thereof will be described in detail. A through hole 34 is formed in the heat insulating door 3 at a position where the spout 31 is attached. Pouring section 3
Reference numeral 1 denotes a block formed of a synthetic resin material, and a pouring passage 38 is formed vertically in the center of the inside. A short circular boss portion 45 is formed at the lower end of the back surface of the pouring portion 31.
6 is fitted, and when the pouring part 31 is attached to the surface of the heat insulating door 3, the boss part 45 is fitted airtightly to the outer end side of the through hole 34.

At the center of the boss portion 45, a circular concave hole 47 is formed. At a position eccentric slightly below the inner surface of the concave hole 47, a mounting hole 48 which is gradually tapered and then reduced in diameter. Are formed. In addition, a communication port 49 whose diameter is further reduced in a stepped manner is formed in the inner surface of the attachment hole 48 and communicates with the lower end side of the pouring passage 38. The connecting pipe 32 is formed of, for example, a stainless steel pipe, and most of the base end (right side in FIG. 2) is formed to have a small diameter that can be fitted into the mounting hole 48, and an O-ring 51 is provided on the outer periphery of the base end. After being fitted, the leading end side is gradually widened, and then the outlet C of the pack B is formed in such a shape that its diameter is expanded so that it can be fitted inside.

As shown in FIG. 4, a pin 55 having a head 56 is provided at the left and right rims of a concave hole 47 provided in the boss portion 45.
On the other hand, a partition plate 61 long in the lateral direction is fitted at a position slightly closer to the base end than the center in the longitudinal direction of the connecting pipe 32, and introduction grooves 63 are provided at both ends thereof. Is provided. And connecting pipe 3
4 is rotated counterclockwise from the position shown in FIG. 4 and inserted into the mounting hole 48 of the spouting section 31, and then rotated clockwise, the locking hole 62 is moved from the introduction groove 63 into the pin 5.
By turning around the back side of the head 56 of the No. 5, it is attached in a retaining state. At this time, a substantially annular ventilation space 65 is formed around the base end side of the connecting pipe 32 and the concave hole 47, and an inlet is formed above the partition plate 61 and an outlet is formed below the partition plate 61. .

The lower surface of the pouring section 31 is
It is formed on an inclined surface 67 that is inclined downward toward the back. And, at the lower end of the above-described pouring passage 38,
A mounting hole 70 for mounting a cap 80 provided with a spout 82 is formed. The mounting hole 70 is provided above the large diameter portion 71 with a screw hole 7 having a female screw 72 cut on the inner peripheral surface.
3 is formed in a stepped shape, and a stopper hole 74 slightly larger in diameter is formed above the stepped portion.

The cap 80 is formed of a synthetic resin material into a cylindrical shape having an upper surface plate 81. This top plate 81
Is thick and formed so as to form a downwardly conical shape as a whole, and at the center thereof is formed an octagonal star-shaped spout 82 as shown in FIG. Cap 80
Is formed in a stepped shape whose diameter is reduced in four steps upward. In particular, on the outer peripheral surface of the second stage from the top,
Male screw 8 that can be screwed into female screw 72 of screw hole 73 described above.
3 is cut off. However, the diameter M of the thread of this male screw 83
1 is previously formed a little smaller than the diameter M2 of the root of the female screw 72. For example, if M2 = 36, M
1 = about 35.5. The uppermost step above the male screw 83 is a circumferential guide surface 84 that fits almost tightly inside the female screw 72, and has a C surface at a corner.

The discharge passage 38 is formed in a stepped shape whose diameter is slightly reduced in the upper part from the center height position, and a valve element 40 is fitted in the discharge passage 38 so as to be able to move up and down. .
The valve body 40 is also made of a synthetic resin material,
It is formed in the shape of an elongated rod with a step, whose diameter is enlarged stepwise. At the lower end of the valve body 40, a pair of upper and lower O-rings 39 are provided at an interval slightly larger than the diameter of the communication port 49.
Is fitted. The lower end surface of the valve body 40 has a conical shape following the shape of the upper surface plate 81 of the cap 80 described above. At the center of the conical portion 90, as shown in FIG.
1 is formed. The corners of the protrusion 91 are rounded.

On the other hand, the tip of the cock 23 rotatably supported on the upper side of the outer surface of the pouring section 31 is inserted and connected to a connection hole 92 formed in the valve body 40. When the cock 23 is at the upper position, the valve body 40 is at the lowered position shown in FIG. 2, and the communication port 49 is closed with the upper and lower O-rings 39 positioned above and below the communication port 49. When the lowering operation is performed, the valve body 40 rises and as shown in FIG. 3, the rising is restricted by hitting the stepped portion 93 of the pouring passage 38, and the bottom of the conical portion 90 is connected to the communication port 49. With the upper edge reached, the communication port 49 and the spout 8
2 is open.

Next, the operation of the present embodiment will be described. When the pack B is accommodated in the pack accommodating chamber 16 with the ejection cylinder 12 tilted, and the ejection cylinder 12 is raised, as shown in FIG.
2 is fitted and connected in the enlarged diameter end portion. To pour out the ice cream A, hold the container (not shown) in the hand and insert it below the spout 82, and when the cock 23 is opened, the valve 40 moves to the raised position shown in FIG. At the same time as 49 is opened, the discharging switch 29 is turned on, the pump 27 is driven in the forward direction, and the brine X in the tank 25 is supplied into the pressure chamber 17 of the discharging cylinder 12 and pressurized. As a result, the piston 13 rises to compress the pack B, and the ice cream A flows out of the outlet C of the pack B, passes through the connecting pipe 32, the communication port 49, and the lower end of the pouring passage 38, and flows out of the spout 82. From the container.

Here, a conical portion 90 is formed on the lower surface of the valve body 40. When the bottom of the conical portion 90 reaches the upper edge position of the communication port 49, the communication port 49 is fully opened. As compared with the case where the lower surface of the body 40 is a flat surface, the rising distance of the valve body 40 required to fully open the communication port 49 is small, that is, the up-and-down stroke of the valve body 40 can be reduced.

When the cock 23 is closed after the proper amount is dispensed, the dispensing switch 29 is turned off and the pump 27 is stopped, and the valve body 40 is moved to the lowered position shown in FIG. Is closed and pouring is stopped. At this time, the projection 91 projecting from the lower surface of the valve body 40 is
2 and the ice cream A is poured into the outlet 8
It can be extruded with little stay in 2. That is, the ice cream A is sharply poured out. By repeating the above, ice cream A is sequentially poured out. During this time, when one pouring operation is completed, ice cream A remains in the connecting pipe 32. However, since the ventilation space 65 is formed around the connecting pipe 32, a part of the cold air in the refrigerator is formed. Is cooled to the ventilation space 65 and the temperature of the remaining ice cream A is prevented from rising.

As described above, although the cutting at the spout 82 is improved, there is a possibility that the ice cream A is still attached and remains particularly at the back of the star shape, and this portion is directly exposed to the outside air. Therefore, it is necessary to wash the germs appropriately as they are in an environment where bacteria can easily propagate. In that case, the cap 80 may be loosened and removed from the mounting hole 70 of the spouting section 31, and the washing may be performed. At this time, from the viewpoint of sterilization and the like, it is preferable to perform cleaning using hot water. After the cleaning is completed, the cap 80 is again screwed into the screw hole 73 of the mounting hole 48 and mounted. Here, as described above, when the cap 80 is washed with high-temperature hot water, the cap 80 is thermally expanded because the material is a synthetic resin, and the female screw 72 on the mounting hole 70 side is disposed on the front surface of the freezer. Therefore, since the male and female screws 72 and 83 are formed to have the same diameter because they are cooled and rather contracted, the male screw 83 may not be screwed into the female screw 72 in some cases.

In this respect, in this embodiment, the diameter M1 of the crest of the male screw 83 is formed to be slightly smaller than the diameter M2 of the trough of the female screw 72 in advance. The screw 83 can be screwed. Further, the lower surface of the discharging portion 31 is formed as an inclined surface 67 for draining dew condensation water, and there is a possibility that the cap 80 may be inclinedly inserted into the mounting hole 70 when the cap 80 is mounted.
A guide portion 84 which is not threaded is formed on the upper side of the female screw 72. When the cap 80 is inserted into the mounting hole 70, the guide portion 84 first fits almost tightly inside the female screw 72. And then male and female screws 72,
83 acts so as to be screwed together, so that both screws 72 and 83 can be smoothly engaged with each other.
Can be easily installed.

As described above, according to the present embodiment,
When the valve body 40 is lowered to the lowered position in order to stop the pouring of the ice cream, the projection 91 on the lower surface of the valve body 40 is moved out of the spout 8.
2, the ice cream A which is going to remain in the spout 82 can be pushed out, so that it can be poured out sharply. Therefore, the ice cream A remaining in the spout 82 does not melt and drip, and is free from the troublesome work of frequently wiping it to prevent it. In addition, since such an extrusion method can be applied to a case where the rim of the spout 82 is made thick, it is extremely suitable when applied to a hard-type ice cream spout structure requiring high strength.

Also, a cap 80 having a spout 82 formed therein
The diameter of the male screw 83 provided in the mounting hole 7
Since the diameter of the female screw 72 is set smaller than the diameter of the female screw 72 in advance, the screw can be securely screwed even when the cap 80 is washed at a high temperature and thermally expanded. The male and female screws 7
2, 83 can be smoothly engaged. <Other Embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings, and can be variously modified and implemented without departing from the gist thereof.
