Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a cold storage container of a frozen dessert manufacturing apparatus for ice cream, sorbet and the like used in general households.

[0002]

2. Description of the Related Art Generally, in a frozen dessert making apparatus of this type, it is necessary to put a cold storage container in a freezing room for more than ten hours in advance to cool the cold storage agent to a predetermined temperature or lower before use.

[0003]

However, in the conventional cold storage container, there is no method for judging the temperature of the cold storage agent immediately after taking it out from the freezing chamber, and it is empirically predicted by the time when the cold storage container was in the freezing chamber. . Therefore, there is a problem in that the accurate cooling temperature of the cold storage agent cannot be grasped and the quality of the frozen dessert is affected.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a cold storage container in which the temperature of the cold storage agent can be easily visually observed.

[0005]

In order to achieve the above object, the present invention provides a container comprising an outer case, an inner case made of a heat conductive material such as aluminum, and a fin closely attached to a wall of the inner case. The container is provided with a cold storage agent filled between an outer case and an inner case, and a temperature sensing plate is provided on the container so that the temperature sensing plate can be visually observed.

Further, the temperature sensing plate is provided in the regenerator,
The temperature can be displayed digitally or can be displayed in a color change for easy understanding.

[0007]

In the present invention, the temperature of the cold storage agent is directly sensed in the cold storage agent and displayed at a position where it can be visually observed, so that the accurate cooling temperature of the cold storage agent can be known.

Further, since the sensed temperature is digitally displayed or is displayed by color change, it is possible to accurately grasp the cooling temperature and make a frozen dessert without failure.

【Example】

(Embodiment 1) An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 3, the exterior body 1 adopting the double peripheral wall structure has a bottomed cylindrical shape with an upward opening, and accommodates the cool storage container 2 therein so that it can be freely taken in and out.

The cold storage container 2 includes a side wall fin 5 closely attached to the side wall of the inner case 4 and a bottom wall fin closely attached to the bottom wall between the outer case 3 and the inner case 4 made of a material having good heat conductivity such as aluminum. 6, and the fins 5 and 6 are also made of a heat conductive material such as aluminum. Its shape is set as a bottomed cylindrical shape with an upper opening, and the open ends of the cases 3 and 4 are joined by means such as caulking,
Further, a ring 7 made of synthetic resin is provided on the joint.

A closed space 8 between the outer case 3 and the inner case 4 of the cold storage container 2 is filled with a cold storage agent 9 containing propylene glycol, pure water and the like as main components. The temperature sensing plate 10 held and provided on a part of the sidewall fins 5 immersed in the storage material 9 has a surface 11 made of a substance that changes with temperature, and when the temperature reaches a predetermined temperature, the temperature is digitally displayed. The temperature displayed on the temperature sensing plate 10 can be visually observed from the outside by the transparent window 12 provided on the side wall of the outer case 3 for reversible display or color change display. There is.

The lid 13 made of a transparent material that opens and closes the upper opening of the exterior body 1 uses the bayonet mechanism to form the exterior body 1.
Is removably connected to the base material, and a material input port 14 is formed in a part thereof. Further, the driving body 15 is provided in an L shape over the diameter direction of the upper surface of the lid 13 and the longitudinal direction of the outer periphery, and the driving body 15 has a built-in motor and a reduction mechanism, and a rotation output section corresponding to the central portion of the lid 13. It has 16. Then, the stirring body 17 in which the shaft portion 18 is detachably attached to the rotation output portion 16 of the drive body 15 has a substantially mountain-shaped scraping piece 19 which rotates in proximity to the inner peripheral surface and the inner bottom surface of the cold storage container 2. Further, the scraping piece 19 has a pair of stirring pieces 20 provided upright on the predetermined inner peripheral side.

In the above structure, when making ice cream, for example, the cold storage container 2 is put in the freezer compartment of the refrigerator for several hours in advance for cooling. Then, the door of the freezer is opened and the contents displayed on the temperature sensing plate 10 through the transparent window 12 are visually inspected to see if the cold storage agent 9 in the cold storage container 2 is cooled to a predetermined temperature or lower.

After confirming that the cold storage container 2 is cooled to a predetermined temperature or lower, the cool storage container 2 is set in the exterior body 1 and its upper opening is closed by a lid 13 having a stirring body 17 set therein. Next, a so-called ice cream material in which egg yolk, fresh cream, sugar and the like are melted with milk is charged into the stirring chamber 21 in the cold storage container 2 through the material charging port 14.

When the driving body 15 is energized, the agitating body 17 cools the ice cream material while agitating it, and after a predetermined period of time, the ice cream material is entirely frozen to form an ice cream.

By the way, the cold storage container 2 is provided with an inner case 4 and side wall fins 5 and bottom wall fins 6 closely attached to the inner case 4.
And are formed of a heat conductive material such as aluminum, and the surface area in contact with the cold storage agent 9 is made as large as possible. Therefore, the cold temperature of the cooled cold storage agent 9 is efficiently transmitted to the ice cream material etc., and quickly and well A cold and delicious frozen dessert can be surely made, and since the temperature sensing plate 10 is held by the side wall fins 5 and immersed in the cold storage agent 9, the temperature is accurately sensed and the transparent window 12 is used to You can easily see the display temperature from.

[0018]

As described above, according to the present invention, by providing the temperature sensing plate for displaying the temperature of the cold storage container, it is possible to grasp and judge the cooling capacity at the time when the cold storage container is taken out of the freezer, so that the frozen dessert can be surely made without failure. Can be made.

Further, by providing the temperature sensing plate in the regenerator, the temperature can be directly sensed accurately. Furthermore, since the detected temperature of the cold storage agent is displayed digitally or is displayed by changing the color, there is an excellent effect that the degree of cooling can be easily judged visually.
