Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an apparatus for producing ornamental ice in which luminous bodies are disposed in water.

[Prior art]

Decorative ice is used to add excitement to various event venues. Traditionally, decorative ice displayed at fairgrounds had to be manufactured at a specialized ice factory. For this reason, it took time to transport the ice from the factory to the venue, and as the ice melted during that time, a special refrigerated truck had to be prepared for the transport.

Furthermore, when displaying at a venue, it is advisable to adjust the timing, and if there is a long waiting time or display for a long time, great consideration must be given to melting.

Furthermore, the decorative ice produced at ice factories is limited to rectangular parallelepiped ice cubes made from ice cream cans, and is usually decorated with fresh or artificial flowers in the water, which lacks interest.

For the above reasons, it is an object of the present invention to provide an apparatus for producing decorative ice that can be produced with little use of decorative ice.

[Key points of the invention]

The decorative ice making apparatus according to the present invention includes a box, a refrigeration unit housed in the box, a tray-shaped ice box placed on the box, and a refrigerant disposed at the bottom of the ice box. It is characterized by comprising a tube and an in-ice light emitting means attached to the ice box.

[Embodiments of the invention]

An embodiment of the present invention will be described below based on the drawings.

In the figure, wheels 12 are attached to the bottom of a box 10 so that the box 10 is movable. A refrigeration unit 14 is housed within the box 10.

The refrigeration unit 14 is a known refrigeration device, and the refrigeration machine 1
6. Condenser 18. Expansion valve 20. and piping 22 that connects these devices. The interior surrounded by the switching valves 24, 26° 32 forms an ice making chamber 34. There is a heat insulating material 3 inside the case 32.
6, and a refrigerant pipe 38 is disposed on the bottom and upper surface, and a tape heater 40 is disposed on the side surface.

One end of the refrigerant pipe 38 is connected to the refrigeration unit 14 via an outbound connection pipe 42, and the other end is connected to the refrigeration unit 14 via an inbound connection pipe 44.

Light-emitting bodies 46 can be installed in the ice-making compartment 34, and these light-emitting bodies 46 are electrically connected to a light emission control means 48 to control their blinking. An operation panel 50 for the refrigeration unit 14 is provided at the bottom of the box 10.

Next, how to use the apparatus of the second embodiment will be explained. This device is mainly used at event halls. First, the ice making compartment 3 of the ice box 30
4, a light emitting body 46 is laid out in a desired shape. In order to facilitate the attachment and fixing of the light emitter, the light emitter may be fixedly placed at a predetermined position in the ice making compartment in advance. Thereafter, these light emitters are electrically connected to the light emission control means 48. After completing the installation of the light emitter 46, fresh water or colored water is poured into the ice making chamber 34 to a predetermined level.

Next, connect the commercial power supply (not shown) to the operation panel 5 of the refrigeration unit.
0 and operate the refrigeration unit 14.

The refrigerant of the refrigeration unit is passed through the outgoing connection pipe 42. Refrigerant pipe 38, return connection pipe 44. The refrigerant unit) 14 is circulated in this order to freeze the water in the ice making compartment 34. The refrigerating capacity of the refrigerant unit 14 may be such that the water in the ice making compartment 34 freezes in 8 to 24 hours. In other words, the layout of the nine light emitters 46 is done the day before,
Ice is made unmanned at night. After ice making is completed, low load operation is performed to prevent the ice from melting. At the exhibition venue, the light emission control means 4 is operated while maintaining the low load operation of the refrigeration unit 14.
8 controls the blinking of one light emitter.

When using a tray-shaped ice box like the one of the present invention.

It's so dark and blurry that I can't float. On the other hand, in the case of the present invention using an in-ice luminescent material, by emitting various colored lights from opaque water, the light is scattered appropriately and a fantastic atmosphere can be created. This is especially effective in increasing interest in dimly lit environments.

Furthermore, since the flickering of the light emitters can be freely controlled by electrical means, the display display can be changed one after another while synchronizing with music, for example. Since the ice is opaque, it is difficult to see from the outside the wiring connected to the light emitter, the attachment of the light emitter, and the existence of the light emitter that has stopped emitting light, making it possible to highlight only the desired design. The device of this embodiment can be permanently installed not only in an event hall but also in a restaurant, for example, and used as a table for serving buffet dishes. Especially fruits and ice cream.

It is suitable as a mounting table for things that need to be kept cool, such as juice.

Then, the refrigerant is operated with hot gas to melt the ice. After melting, the water is drained from a drain port (not shown).

In the embodiments described above, a direct expansion type refrigeration system was shown as the refrigeration unit. However, the refrigeration unit is not limited to this, and may be an indirect cooling type using brine or one that makes ice using the latent heat of vaporization of liquid nitrogen. Further, one device does not need to be movable, and may be permanently installed at a required location.

Further, the ice box does not need to be fixed in a single box and always kept horizontal, but may be erected at any angle for easy viewing after ice making is completed.

〔Effect of the invention〕

According to the above nine decorative ice manufacturing apparatuses according to the present invention.

The ice making device can be used to produce ornamental display devices and ice. For this reason, it can strongly appeal to viewers.
