Description

[Detailed description of the invention] (Field of industrial application) This invention is an ice cream making device, specifically an ice cream date shear, an ice cream date parr, etc., which are mainly used when selling ice cream in a case at a store. This relates to ice cream making equipment.

(Prior Art) An ice cream making device consists of a grip part and a cutting part provided at the tip of the grip part, and the ice cream is made by gripping the grip part and using the cutting part.

For example, a conventional ice cream puncher is made of aluminum casting, and as shown in FIGS. 7, 8, and 9, it consists of a grip part 1 and a cutting part 2 provided at the tip thereof. The grip part 1 is hollow, and a heat storage fluid (emulsified liquid) 3 is sealed inside.

When using this day par, the heat from your hands is stored in the heat storage fluid 3 sealed through the tube wall, and during the work of making ice cream, the heat storage fluid 3 moves to the tip, warming the making part 2 and making ice cream. It is designed to make paper making easier.

Furthermore, an ice cream scoop using a heat pipe filled with hydraulic fluid in its handle was invented in 1983.
This was disclosed in Japanese Patent Publication No. 151046, and an electric ice cream dispenser with an electric heating element embedded in the head and a conductive cord connected to it was also published in the 1980s.
It is disclosed in Publication No. 15326.

In addition to this kind of ice cream date shear, conventional ice cream making equipment includes a mechanical ice cream date shear that is equipped with a scraper in the cutting part, and when the grip is squeezed, the scraper rotates half a rotation with a rack pinion. Yes (see Figure 5).

(Disadvantages of the Prior Art) However, the conventional ice cream making apparatus as described above has the following disadvantages.

That is, the conventional ice cream dessert sheeter has a structure in which hard ice cream is simply scraped off mechanically with a scraper, and therefore has the drawback of placing a lot of strain on the user's wrist.

If the ice cream is made many times and continuously, the temperature of the cup, which is the part where the ice cream is made, approaches -20°C, which is the temperature of ice cream, making the process even more difficult.

Also, regarding ice cream dates par,
The sealed heat storage fluid warms the making part, which is good for making ice cream once or twice, but if you make it continuously, the amount of heat stored in the heat storage fluid is small, so the making part is heated. The cold part gets so cold that it becomes difficult to make ice cream.

To make papermaking easier, it is possible to warm the grip, but this requires warming the grip with the hand facing down or soaking it in hot water, which makes work extremely difficult. Put it away.

Another drawback was that if the date parser was left in an ice cream case when not in use, it would get too cold.

Therefore, even when using a dipper, a considerable amount of strength is required to squeeze ice cream continuously, and since most ice cream sales at stores are handled by female employees, the reality is that the task of squeezing ice cream causes wrist strain.

Figure 4 is a graph showing the changes in the temperature of the grip surface, the tip of the cutting part, and the ice cream when ice cream is made eight times in a row using the conventional ice cream scooper as described above. It is.

As can be seen from this graph, from the fifth time onwards, the temperature at the tip of the paper cutting section decreased to about -5°C, making paper production difficult.

In this regard, with an electric ice cream dispenser that has an electric heating element embedded in the head and a conductive cord connected to it, the head that makes ice cream does not get cold, so it is possible to make ice cream continuously. However, since the conductive cord is connected to many parts, it not only becomes a nuisance during use, but also causes the cord to come into contact with other objects, which is not desirable in terms of food hygiene.

(Purpose of the invention) The purpose of the invention is to eliminate the drawbacks of the conventional ice cream making equipment as described above, and to make it hygienic and easy to make ice cream continuously. .

(Structure of the invention) In order to achieve this object, the ice cream making device of the present invention is an ice cream making device consisting of a grip portion and a cutting portion provided at the tip of the grip portion. It is formed into a double tube shape, and the outer tube is used as a heat tube, and the inner tube is equipped with a pack of oxidizing exothermic agent or a heating element using a battery and a heater. A working fluid such as fluorocarbon refrigerant is filled in the space between the paper cutting section and the paper cutting section.

Note that the term "heat tube" as used herein refers to a tube in which a heat medium is sealed and heat exchange is performed by the flow of the medium.

(Actions and Effects of the Invention) Since the ice cream making device of the present invention has the above-described configuration, it has the following effects. In other words, heat is effectively supplied to the cutting section from the entire circumference of the heating element built into the grip through the heat pipe, so even if the ice cream cutting operation is continuous, it can be carried out efficiently and the work can be done efficiently. It is possible to reduce fatigue on the hands of the operator.

Since the grip portion is also heated by the heating element, the operator will not feel discomfort due to cooling.

Regardless of whether a papermaking device is equipped with a heating element inside, it is not connected to any cords and is in a separate state, so when used, it can be used as a traditional papermaking unit and a grip unit. It is also easy to use, and it is hygienic because there are no cords.

This effect is achieved.

(Embodiments) Embodiment 1: FIG. 1 is a cross-sectional view of an ice cream maker which is an embodiment of the ice cream maker of the present invention.

10 is a grip part, 11 is a papermaking part, 12 is a heating element,
13 is a heat pipe. The grip portion 10 has a double structure consisting of an outer tube 14 and an inner tube 15. The outer tube 14 itself constitutes the heat tube 13, and the heating element 12 is housed within the inner tube 15.

The heating element 12 is a pack of an oxidizing exothermic agent, and is adapted to cause an exothermic reaction by movement of air around the exothermic powder.

The inner tube 15 is closed with a removable plug 16 and is provided with a ventilation hole 17 to supply air to the heating element 12.

A working fluid 18 is sealed as a heat medium in the space between the outer tube 14 and the inner tube 15, and between the head of the inner tube 15 and the cutting section 11. A heat tube 13 is configured. More specifically,
A fluorocarbon refrigerant that evaporates at low temperatures is filled as a working fluid 18 at low pressure.

When the ice cream date parr as described above is squeezed, the heat retained in the hand releases the fluorocarbon refrigerant 18.
At the same time, the inner heating element 12
The heat generated evaporates the fluorocarbon refrigerant a, and together the heat is transmitted to the making section 11, making it easier to make the ice cream.

In addition, since a heat pipe is used, latent heat transfer of the working fluid 18 is also possible, and the heating element 12
Since heat is supplied from the ice cream, the ice cream can be made efficiently even if the work is continuous, and the fatigue on the hands of the worker can be reduced. Further, since the grip portion 10 is also appropriately heated, there is no discomfort due to cooling.

In order to effectively generate heat from the heating element 12, it is best to shake the day purer immediately before starting the paper cutting operation to move the heat-generating powder and activate the contact with fresh air. Since the heat-generating powder moves during operation, there is no need to take the trouble of shaking the date par. When not in use, if the date pad is left alone, contact with air is restricted and heat generation is suppressed.

Note that the life of the heating element pack can also be adjusted by changing the capacity of the heating agent depending on its use.

Figure 3 shows the changes in temperature of the heating element, the surface of the grip, the tip of the cutting part, and the ice cream when ice cream was made 12 times in a row using the invented date parser as described above. It is a graph.

Comparing this graph with the graph (Fig. 4) showing the experimental results of the conventional date par described above, the following can be seen.

(b) In contrast to the conventional day par, where the temperature at the tip of the cutting part drops significantly to about -5°C from the fifth time, with the day par of the present invention, the temperature at the tip of the cutting part does not drop significantly; In the graph, the temperature does not go below 0°C.

(b) With conventional date pars, it is difficult to make ice cream because the temperature at the tip of the cutting part drops significantly, so it takes a long time to make ice cream, especially after the fifth time. This can be seen from the fact that the tip temperature remains at negative temperature for a long time (or the width of the valley in the graph is wide).

On the other hand, in the case of the date par of this invention,
Since the temperature at the tip of the cutting part does not drop much, ice cream can be easily made and the time required for one making operation is short.

(c) Conventional date pars require a long time for one paper making operation, and could only be used to make paper 8 times in 5 minutes. I was able to write the paper 12 times.

(d) The temperature of the grip surface of the conventional date par is 15
In contrast, in the case of the date par of the present invention, the surface temperature of the grip only drops to about 20°C, causing discomfort to the worker. do not have.

Embodiment 2: FIG. 2 is a cross-sectional view of an ice cream maker which is a second embodiment of the ice cream maker of the present invention.

The second embodiment differs from the first embodiment in that a planar heater 21, which is generated by a battery 20, is used as a heating element, and the rest is the same as the first embodiment.

The planar heater 21 is attached to the inner wall surface of the inner tube 22, and the battery 20 is housed inside thereof.

A bimetal thermoswitch 23 and a contact 24 are connected to the upper part of the sheet heater 21.
In addition, a cap 26 is provided at the bottom of the planar heater 21.
A spring-like contact 25 provided at the top is connected to the thermoswitch 23, and when the thermoswitch 23 is closed, electricity is applied to the sheet heater 21, which generates heat.

Therefore, in the day par of the second embodiment, when the temperature of the day par is about to drop below a predetermined temperature during the operation of making ice cream, the bimetal thermoswitch 23 closes and the sheet heater 21 generates heat to heat the day par. It is now possible to automatically maintain the date par at a predetermined temperature.

Note that when not in use or when the working fluid is at a predetermined temperature, the bimetal thermoswitch 23 is turned off and no current flows.

FIG. 5 is a sectional view of an ice cream dessert shear having a different configuration from the ice cream making device of the present invention.

30 is a grip part, 31 is a papermaking part, 32 is a heating element,
33 is a heat tube.

The grip part 30 is made of hard plastic and consists of a heating element accommodating part 34 and a cutting part coupling part 35. A cutting part base 36 is fitted into the coupling part 35, and the cutting part 31 and the grip part 30 are connected to each other. combined.

The paper cutting section 31 consists of a paper cutting section main body 37 which is integrated with the base 36, and a scraper 38, and the scraper 38 is adapted to be rotated by a half turn by a rack pinion 39 as in the prior art.

As shown in FIG. 6, the heat tube 33 has a heat receiving plate 40 fixed to its lower portion, and its upper portion extends to the sheeting portion main body 37 through the sheeting portion base 36. The heat receiving plate 40 is in contact with the heating element 32,
It plays the role of efficiently transmitting the heat to the heat tube 33.

As the heating element 32, a pack of oxidizing exothermic agent is used as in the first embodiment.

Ice cream date shears like the ones above are
As in the past, ice cream can be mechanically made by rotating the scraper 38, and heat from the heating element 32 can be supplied to the making section 31 through the heat tube 33, making the ice cream making process easy. can be performed consecutively.

At this time, since the grip part 30 is made of plastic, there is little heat dissipation, so even if the heat is taken away from the making part 31 when making ice cream, it will recover by the time the ice cream is made next time. That will happen.
