(Structural example of heat storage device 400)
FIG. 5 shows the refrigerator 1 shown in FIG. 1, and shows a state in which the drawer-type door 10 of the ice-making chamber 4 of the refrigerator 1 and the drawer-type door 11 of the upper freezing chamber 5 are pulled out toward the front. In the storage container 4M of the ice making chamber 4 and the storage container 5M of the upper freezing chamber 5, one or more heat storage containers 400 can be stored in at least one storage container. Further, at least one of the storage containers 6M and 6N in the lower freezing chamber 6 can also store one or a plurality of heat storage containers 400.

By storing the heat storage devices 400 shown in FIG. 5 in at least one of the storage container 4M of the ice making chamber 4 and the storage container 5M of the upper freezing chamber 5 in a state where they are stacked in two stages, for example, they can be taken in and out. The refrigerator 1 can rapidly freeze, for example, a hot food storage device 400 containing a small amount of hot cooked rice immediately after being cooked by a rice cooker, which is a “hot food”.

FIG. 6 is an exploded perspective view showing a preferable structural example of the heat storage device 400 shown in FIG. FIG. 7 shows a state in which a plurality of heat storage devices 400 are stacked and stored in the storage container 4M of the ice making chamber 4 or the storage container 5M of the upper freezing chamber 5.

As shown in FIG. 6, the heat storage device 400 has a storage body 401 and a lid member 420. The storage body 401 has a flat plate portion 402 and four leg portions 405.

As shown in FIGS. 6 and 7, the flat plate portion 402 is, for example, a square or rectangular plate material, and a recessed heat storage portion 410 is formed in the center of the flat plate portion 402 so as to project downward. There is. The hot material storage portion 410 of the hot material storage device 400 is, for example, a hemispherical hollow, and a small amount of cooked rice M freshly cooked with a hot material such as a rice cooker is contained in the hot material storage portion 410. Can be stored, for example, about 150 g. Therefore, the hot material storage portion 410 of the hot material storage device 400 can easily store, for example, a serving of hot rice M in a separate amount.

As shown in FIGS. 6 and 7, the upper ends of the four leg portions 405 are fixed to the positions of the four corners of the flat plate portion 402, respectively, and the four leg portions 405 are the hot material storage portions 410 of the flat plate portion 402. The cold air passages S and S1 through which the cold air passes are formed so that the cold air C and C1 can be easily touched in a floating state.

The lid member 420 is, for example, a square or rectangular plate material having the same size as the flat plate portion 402, and by closely superimposing the lid member 420 on the flat plate portion 402, the heat material storage portion 410 is hermetically covered.

As a result, the lid member 420 can seal and freeze a small amount of cooked rice M cooked by a rice cooker or the like stored in the hot material storage portion 410. Therefore, the cooked rice M stored in the hot food storage portion 410 can be easily divided into full-fledged cooked rice M and quickly frozen so that the odor does not transfer from the stored food such as other foods.

As the material of the heat storage device 400 shown in FIG. 6, preferably, for example, a resin having heat resistance and cold resistance such as silicone and having softness can be adopted. In this way, by making the heat storage device 400 made of a resin having heat resistance and cold resistance such as silicone and having a softness, the heat material storage device 400 containing the frozen cooked rice M can be kept as it is. You can put it in the microwave and heat it in the microwave as it is.

Further, as the material of the heat material storage device 400, the entire heat material storage device 400 or a part of the heat material storage portion 410 or the like is made of a material having high thermal conductivity such as aluminum. This makes it easier to cool the cooked rice with cold air and allows it to be frozen faster.

The heat material storage portion 410 shown in FIG. 6 is formed so as to project downward, and the depth D of the heat material storage portion 410 is preferably 30 mm or less. As a result, as shown in FIG. 7, the stored cooked rice M can secure a large surface area to be cooled by the cold air C and C1. Moreover, since the thickness of the stored cooked rice M in the vertical direction becomes thin, the cooked rice M can be quickly and uniformly quickly frozen.

As shown in FIG. 7, the heat insulating material 500 can be arranged on the inner surface, the outer surface, or both sides of the heat material storage portion 410. As a result, the hot material storage device 400 is placed in the storage container 4M of the ice making chamber 4 or in the storage container 5M of the upper freezing room 5 and cooled in advance before storing the cooked rice M which is a hot material. Therefore, since the heat dissipation of the cooked rice M, which is a hot substance, can be improved, the cooked rice M can be quickly frozen.

The material of the lid member 420 can be made of a material having high thermal conductivity such as aluminum. As a result, the cooked rice M, which is the hot food stored in the hot food storage portion 410, is in contact with the lid member 420, so that the heat dissipation of the cooked rice M can be improved, so that the cooked rice M can be quickly frozen. Can be done.

As the material of the heat storage device 400 shown in FIG. 6, preferably, a material having an antibacterial action is kneaded or coated on the surface. As a result, the heat storage device 400 has antibacterial properties and can be used cleanly.

As illustrated in FIG. 7, the above-mentioned heat storage device 400 can be stored in the storage container 4M of the ice making chamber 4 or in the storage container 5M of the upper freezing chamber 5 by stacking two or more, for example.

As shown in FIG. 7, the cooked rice M cooked by a rice cooker or the like is stored in the hot food storage portion 410 of the lower hot food storage device 400, and the cooked rice M in the hot food storage portion 410 has a lid. It is sealed by a member 420. The cooked rice M cooked by a rice cooker or the like is stored in the hot food storage portion 410 of the hot food storage unit 400 in the upper stage, and the cooked rice M in the hot food storage portion 410 is sealed by the lid member 420. ..

The lower heat storage device 400 is supported by the lower ends of the four legs 405 on the inner bottom surface 4B of the storage container 4M of the ice making chamber 4 or on the inner bottom surface 5B of the storage container 5M of the upper freezing chamber 5. Has been done. The upper heat storage device 400 is supported by the lower ends of the four legs 405 on the upper surface 420F of the lid member 420 of the lower heat storage device 400.

As a result, in the lower heat material storage device 400, a cold air passage S for passing the cold air C is formed between the heat material storage portion 410 and the inner bottom surfaces 4B and 5B, as shown by arrows. Similarly, in the upper heat material storage device 400, a cold air passage S1 for passing cold air C1 is formed between the heat material storage portion 410 and the upper surface 420F of the lid member 420, as shown by an arrow.

Therefore, in the lower heat material storage device 400, the cooked rice M, which is the heat material stored in the heat material storage portion 410, is directly cooled by the cold air C passing through the cold air passage S, so that the heat dissipation of the cooked rice M is improved. Yes, cooked rice M can be quickly frozen. Similarly, in the upper heat material storage device 400, the cooked rice M, which is the hot material stored in the heat material storage portion 410, is directly cooled by the cold air C1 passing through the cold air passage S1 and the cold air C1 passing over the lid member 420. As a result, the heat dissipation of the cooked rice M can be improved, and the cooked rice M can be quickly frozen.

As described above, two or more heat storage devices 400 are stacked in the storage container 4M of the ice making chamber 4 or in the storage container 5M of the upper freezing chamber 5 via the four legs 405 to generate heat. The rice rice M, which is a product, can be rapidly frozen, for example, by effectively utilizing the storage container 4M of the ice making chamber 4 or the storage container 5M of the upper freezing chamber 5.

When two or more heat storage devices 400 are stacked, four legs 405 are used to secure the cold air passage S (S1).

(Storability of multiple heat storage devices 400)
By the way, when two or more heat material storage devices 400 are not used, the two or more heat material storage devices 400 are in the storage container 4M of the ice making chamber 4, the storage container 5M of the upper freezing chamber 5, or the like. I want to store it compactly in a storage place such as a cupboard.

Therefore, as illustrated in FIGS. 8 and 9, for example, the two heat storage devices 400 are devised so that the two heat storage devices 400 can be compactly stored.

As shown in FIGS. 6 and 8, the flat plate portion 402 has four through holes 415 near the four corners. As shown in FIG. 8, these through holes 415 are the four legs 405 of the heat storage device 400 located on the upper side when the plurality of sets of heat storage devices 400 are stored without being used. Through. As a result, the stacking height of the plurality of heat substance storage devices 400 can be reduced, and the space occupied by the plurality of heat substance storage devices 400 can be reduced.

More specifically, as shown in FIG. 8, through holes 415 are provided at the four corners of the flat plate portion 402 of the lower heat storage device 400, respectively. These through holes 415 of the lower heat storage device 400 are formed at positions immediately adjacent to the four legs 405 of the flat plate portion 402 of the lower heat storage device 400.

On the other hand, in the flat plate portion 402 of the upper heat storage device 400, the positions of the four legs 405 are one at the positions of the four through holes 415 of the flat plate portion 402 of the lower heat storage device 400, respectively. I am doing it. The positions of the four legs 405 of the flat plate portion 402 of the upper heat storage device 400 are offset from the positions of the four legs 405 of the flat plate portion 402 of the lower heat storage device 400, respectively.

As a result, as shown in FIGS. 8 and 9, when the upper heat material storage device 400 and the lower heat material storage device 400 are to be stacked in order to store the two heat material storage devices 400, the upper stage heat material storage device 400 and the lower stage heat material storage device 400 are to be stacked. The four legs 405 of the flat plate portion 402 of the upper heat storage device 400 pass through the four through holes 460 of the flat plate portion 402 of the lower heat storage device 400, respectively, and the heat of the upper heat storage device 400 is passed. The material storage portion 410 enters the inside of the hot material storage portion 410 of the lower heat material storage device 400.

Then, as shown in FIGS. 8 and 9, the lid member 420 of the upper heat storage device 400 and the lid member of the lower heat storage device 400 are placed on the flat plate portion 402 of the upper heat storage device 400. Place the 420s on top of each other.

Therefore, in order to enable compact storage when the two heat material storage devices 400 are not used, the stacking height H when the two heat material storage devices 400 shown in FIG. 9 are stacked is shown in FIG. 7. As described above, the stacking height P when two heat storage devices 400 are stacked for quick freezing of cooked rice M can be made smaller.

Therefore, when not in use, the two heat storage devices 400 are placed in the storage container 4M of the ice making chamber 4, the storage container 5M of the upper freezing chamber 5, or other storage places such as a cupboard. , Can be stored compactly. Therefore, the space occupied by the two heat storage devices 400 when not in use can be reduced.

Next, FIGS. 10 and 11 show preferable structural examples in the storage container 4M of the ice making chamber 4 or in the storage container 5M of the upper freezing chamber 5. In FIG. 10, a heat conductive material 500 having high heat conductivity such as aluminum is arranged on the inner bottom portion in the storage container 4M of the ice making chamber 4 or the inner bottom portion in the storage container 5M of the upper freezing chamber 5.

As a result, if the heat conductive material 500 is cooled in advance by quenching in the storage container 4M of the ice making chamber 4 or in the storage container 5M of the upper freezing chamber 5, the heat material storage device 400 containing the hot rice M is stored. By placing the heat conductive material 500 on the heat conductive material 500, the hot rice M can be rapidly frozen faster.

In FIG. 11, a heat insulating material 520 such as expanded polystyrene is arranged at the inner bottom of the storage container 4M of the ice making chamber 4 or the inner bottom of the storage container 5M of the upper freezing chamber 5.

As a result, if the heat insulating material 520 is previously cooled by quenching in the storage container 4M of the ice making chamber 4 or in the storage container 5M of the upper freezing chamber 5, the heat insulating material 400 containing the hot rice M is stored. By placing it on the heat insulating material 520, the hot rice M can be quickly frozen quickly.

The heat conductive material 500 shown in FIG. 10 and the heat insulating material 520 shown in FIG. 11 can be combined at the same time. The heat conductive material 500 and the heat insulating material 520 can be arranged not only on the inner bottom portion in the storage container 4M of the ice making chamber 4 or the inner bottom portion in the storage container 5M of the upper freezing chamber 5, but also on the side surface portion.

(Example of using refrigerator 1 when quick freezing cooked rice M, which is a hot product)
Next, an example of use in quick freezing cooked rice M, which is a hot product, will be described using the refrigerator 1 described above.

The cooked rice M, which is a hot product cooked by the rice cooker or the like shown in FIG. 6, is stored in the hot material storage portion 410 of the hot material storage device 400, and a lid member is placed on the storage body 401. Put 420 on it.

As a result, the lid member 420 is sealed so as to cover the cooked rice M of the hot material storage portion 410. The heat storage device 400 that stores the cooked rice M in this way is stacked in two stages, for example, as shown in FIGS. 7 and 5. Then, as shown in FIG. 5, the stacked heat storage device 400 is stored in at least one of the storage container 4M of the ice making chamber 4 and the storage container 5M of the upper freezing chamber 5.

When the user puts the stacked heat storage device 400 in the storage container 4M of the ice making chamber 4, the user operates the ice making chamber mode switching button 311 shown in FIG. 4 to operate the ice making chamber mode display unit. The "quick freezing mode" 332 is selected from the plurality of operation modes displayed in 312.

As a result, the control unit 100 of FIG. 3 rapidly freezes the inside of the storage container 4M of the ice making chamber 4 of FIG. 7, and therefore, as shown in FIG. 7, the cold air C, C1 is inside the storage container 4M of the ice making chamber 4. Passes through the cold air passages S and S1. Therefore, the cooked rice M in the hot material storage portion 410 is rapidly frozen by quenching in a state of being sealed by the lid member 420.
