Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an ice tray used for producing ice in a freezer.

[Conventional technology]

Conventionally, ice making trays have been known in which ice having a small elastic deformation is separated from the ice making tray by deforming the ice making tray using one person's hands after making ice using an ice making tray made of an elastic body.

[Problem that the invention seeks to solve]

However, when the conventional ice tray is transformed manually, it not only gives a very cold sensation to the hand, but also ice that adheres to the surrounding area of the ice tray. There was a problem in that the plate was firmly joined to the plate.

SUMMARY OF THE INVENTION In order to solve these conventional problems, it is an object of the present invention to provide an ice tray that allows ice to be separated from the ice tray without manual deformation.

[The best way to solve the problem]

The ice tray of the present invention, which is used in the production of ice, comprises a part of the ice tray made of a shape memory material that recovers its shape at a temperature higher than 10° C. and below room temperature, and the ice tray is made of a shape memory material that recovers its shape at a temperature higher than 10° C. and below room temperature. Station ice making tray h' - Unlike ice making ice making water shape, it is characterized by deforming into a container shape.

[Effect]

Fill the ice cube tray as shown above with water and make the water diameter below O'C.
When left in a room temperature environment higher than 0°C, the shape memory material memorizes and recovers the next shape, making the ice tray different from the shape at the time of ice making.

tl The water hardly deforms and is separated from the ice cube tray.

〔Example〕

Embodiment 1 of the present invention will be described below with reference to the drawings.

FIG. 1 shows an ice cube tray according to the present invention. It is a perspective view of the F1 side. The inner box 1 of the ice tray is made of highly elastic metal such as stainless steel, and a heat insulating layer 2 having elasticity such as neoprene rubber or polyurethane is bonded to the outside. Further, an outer box 3 made of a shape memory material is bonded to the outside of the heat insulating layer 2. It is higher than the shape recovery temperature fO° C. of the outer box 3 and lower than room temperature. The shape of the ice tray shown in FIG. 1 is the shape when ice is made. That is, it shows the shape of an ice tray that is subjected to IC temperatures below 0°C.

FIG. 2(α) and FIG. 2(b) show the shape of the ice tray at the time of ice making and the shape of the ice tray after the outer box 3h has recovered its shape. When making ice, the ice tray is in the shape shown in FIG. 2 (c). When the ice tray is left in a room temperature environment, the outer box 3 recovers its shape and transforms the ice tray into the shape shown in FIG. 2 (b).

At this time, the ice tray and water are separated because the water hardly deforms.

To make an ice cube tray as shown in Figure 2, the outer box 3, which has the shape shown in Figure 3(b), is deformed into the shape shown in Figure 3(α) at a temperature lower than the shape recovery temperature, and is insulated. Layer 2 and inner box 1 are joined.

Now, when you pour water into the ice cube tray that has the shape shown in Figure 2 at room temperature and start making ice, the temperature of the ice cube tray will be below 0℃, and the temperature of the outer box 3 will be lower than the shape recovery temperature. Become.

At a temperature lower than the shape recovery temperature, the elastic modulus of the outer box 3 becomes smaller, and the outer box 3 is deformed by the elastic force of the inner box 1, and the ice tray transforms into the shape of an ice tray (see Figure 2). Since the specific heat of water is 1 higher than that of the ice tray, it is necessary to leave the ice cube tray in a room temperature environment after the ice has solidified, probably after the ice tray has been deformed in step 7 above. For example, even if the ice temperature h is below 0°C, the temperature of the outer box 3, which is thermally isolated by the inner box 1 and the heat insulating layer 2, rises, reaching the shape recovery temperature r, and the third
In order to transform into the shape of ) in the figure, the ice tray is also in the 2nd UVJ)
It separates ice by deforming into the shape of

Figure 4 shows nine air layers between the inner box 1 and the outer box 3, and the inner box 1 and the outer box 1 are interlocked with S heat material 4 such as plastic in several places. In this example,
The above-mentioned heat insulating layer 2 acts as an island, or there is a layer of air h''-.If the ice tray is refined in this way, it will be made into a light ice tray.

In accordance with the above embodiments, the cell shape recovery temperature fti of the shape memory material used for the outer box 3 should be higher than 0°C, and as close to 0°C as possible, when left in a room after ice making. 1
This is done in 11th speed.

Claims (1)

[Claims] In an ice tray used for making ice, a portion of the ice tray is made of a shape memory material that recovers its shape at a temperature higher than 0° C. and below room temperature, and the shape recovery of the shape memory material causes the ice tray to retain its shape at the time of ice making. An ice tray that is characterized by being able to transform into different shapes.
