Description

  The present invention relates to a refrigerator and a method for manufacturing an object to be cooled using the refrigerator, and more particularly to a method for manufacturing an object to be cooled that can automatically manufacture ice confectionery such as sherbet and ice cream. Moreover, although this invention is mainly applied to a domestic refrigerator-freezer, it can also be applied to a commercial refrigerator-freezer.

  In general, freezing and refrigeration equipment heats and cools the air through a cooler and blows it to a refrigerator room, freezer room, ice making room, vegetable room, etc., which serves as a food storage room. Cooling is performed in a circulating form in which air heated by cooling is returned to the cooler and cooled again.

  Among them, the freezer not only stores meat and fish, but also stores ice confections such as ice cream and sherbet, and some refrigerator users use it to make it from raw materials. Once, a mixture of sweeteners and fragrances that are raw materials is put in a bowl and put in a freezer, removed from the freezer several times, mixed with a frozen part and an unfrozen part, and then returned to the freezer I made ice confections such as ice cream and sorbet by repeating the operation. Stirring the unfrozen part and the frozen part well has the effect of finely breaking and uniformly dispersing the ice crystals. This makes it possible to obtain a smooth texture when eating ice confectionery. However, this method is very cumbersome, takes more than half a day, and it is necessary to open and close the freezer door many times. There was a problem such as being done.

  For this reason, the container containing the cool storage agent is cooled in advance in the freezer, and the mixture of sweetener and fragrance that is the raw material for ice confectionery is added, and the blades for stirring the raw material are rotated manually or electrically in the container In about 30 minutes, a soft ice cream-like ice confection was produced.

  However, in this method, the ice confectionery component adhering to the container containing the stirring blades and the cold storage agent is not completely removed and is wasteful. Also, since it is very soft, it is generally difficult to shape it into a spherical shape when providing ice confectionery, and it is difficult to provide ice confectionery with a delicious appearance. For this reason, as shown below, the method which can shape ice confectionery in the manufacture process is proposed.

  For example, liquid is put into a rubber balloon, the mouth is stopped with a clip, frozen and frozen, then a little water is poured on the frozen rubber part, and the contents are pushed out from the mouth of the rubber balloon, and the ice is shaped into a round shape. There is a method of taking out (see Patent Document 1).

  In addition, when the liquid object to be frozen introduced into the flow of the liquid refrigerant flowing through the refrigerant flow path is in an unfrozen state, the liquid object to be frozen is brought into contact with each other at the contracted portion and then combined. Some liquid frozen objects are frozen to obtain ice particles having a large particle size (see Patent Document 2).

  In addition, the ice making trays with hemispherical depressions are stacked one above the other, and by injecting a liquid from a small hole opened in the hemispherical depressions on the upper dish, freezing can be obtained to obtain spherical ice. There is an ice tray.

Utility Model Registration No. 3102303 (FIG. 2) JP-A-9-310943 (FIGS. 1 and 2)

  However, since the method of Patent Document 1 freezes from around the ice ball, ice cream or sherbet-like ice confection cannot be manufactured. In addition, the constituent members are easily deteriorated and damaged, and there is a problem in durability.

  In the method of Patent Document 2, since it freezes from around the ice ball in the antifreeze solution, it does not become an ice cream or a sherbet. In addition, post-treatment of the antifreeze liquid is necessary, which places a burden on the user.

  In addition, even a method using a commercially available ice tray cannot freeze ice cream or a sherbet-like ice confectionery because it freezes from around the ice ball.

  The present invention has been made in order to solve the above-described problems, and by automatically stirring and shaping raw materials such as ice cream and sherbet-like ice confectionery in a freezer compartment of a refrigerator, the texture An object of the present invention is to provide a refrigerator and a method for producing an object to be cooled, which can automatically produce ice confectionery and the like having a good design.

Refrigerator according to the present invention has a hemispherical recess in the bottom surface, a cooling pan for storing the liquid or the liquid material to be cooled material, and cold却室you cool the cooling plates, said cooling chamber A vibration applying device that is installed and applies vibration to the cooling dish ;
The indented portion of the cooling dish has a structure in which an object to be cooled that has become semi-solid or solid is rotated in a certain direction to form a spherical shape .
Here, the refrigerator of the present invention has a freezing function. Further, the liquid of the material to be cooled is a mixed solution with water of the raw material that mainly constitutes the object to be cooled, but only water may be used. Moreover, the liquid material of the object to be cooled has fluidity in an uncured state.

The manufacturing method of the object to be cooled according to the present invention was placed in a liquid or liquid product to be cooled material, the cooling plates having a recess of hemispherical accommodated in the cooling chamber of the refrigerator, the cooling plates A first step of cooling the material to be cooled to a semi-solid or solid while applying vibration in an arbitrary direction, and vibration to the cooling plate so that the object to be cooled that has become semi-solid or solid is rotated in a certain direction. And adding a second step of shaping the object to be cooled into a spherical shape.

  The refrigerator according to the present invention has a hemispherical indentation on the bottom surface, a cooling dish for storing a liquid or liquid material of the material to be cooled, a cooling room such as a freezing room for cooling the cooling dish, and a cooling room. By providing a vibration applying device that is installed and applies vibration to the cooling dish, the object to be cooled can be shaped into a spherical shape by using the refrigerator and the vibration applying device installed inside the refrigerator. An object to be cooled such as ice confectionery having a good texture can be automatically made.

  In addition, according to the method for manufacturing an object to be cooled according to the present invention, a liquid or liquid material that is a raw material for ice confectionery or the like stored in a cooling dish is frozen while stirring, and when it becomes semi-solid, it becomes spherical. Since shaping can be advanced, it is possible to provide an object to be cooled such as ice confectionery having a good texture and using a raw material without waste.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Embodiment 1 FIG.
A typical structure and control according to the present invention will be described as a first embodiment. FIG. 1 is a cross-sectional view of the refrigerator according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 denotes a refrigerator body, a refrigerator room 100 arranged with an opening / closing door at the top of the refrigerator body 1, and refrigerators, vegetables, chilled from a freezing temperature zone (−18 ° C.) below the refrigerator room 100 , A switching chamber 200 having a drawer door that can be switched to a temperature zone such as soft refrigeration (−7 ° C.), an ice making chamber 500 having a drawer door in parallel with the switching chamber 200, and a drawer door arranged at the bottom. The vegetable compartment 400 is provided with a drawer door between the freezing room 300, the switching room 200, and the ice making room 500. On the door of the refrigerating room 100, an operation panel 5 comprising an operation switch for adjusting the temperature and setting of each room and a liquid crystal for displaying the temperature of each room at that time is installed. In addition, the operation panel 5 may be installed in the side surface of the refrigerator compartment 100 in a refrigerator, for example.

  The refrigerated room 100 has a chilled room 101 set at a minimum temperature (0 ° C.) at which food can be stored at a temperature higher than the freezing temperature, and a dedicated storage case is provided below the refrigerated room 100. A storage case 301 is installed in the freezer compartment 300 and can store food. A storage case 201 is also installed in the switching chamber 200 and can store food. Similarly, a storage case 401 is installed in the vegetable compartment 400 to store food. Note that the number of cases may be one, but two or more cases may be used in the case where arrangement and the like are improved from the capacity of the entire refrigerator.

  10 is a compressor, 3 is a cooler, 2 is a blower fan that blows the cool air cooled by the cooler 3 to each room in the refrigerator, and 4 is for introducing the cool air cooled by the cooler 3 into each room An air passage 6 is a defrost heater for melting the frost attached to the cooler 3 at regular intervals. The cold air cooled by the cooler 3 passes through the air passage 4 and is blown to the freezing room 300, the switching room 200, the refrigerating room 100, and the ice making room 500 to cool each room. The air that has been blown out into the freezing room 300, the switching room 200, and the ice making room 500 and cooled in each room returns to the lower side of the cooler 3 through the air passage 4 from the suction port provided in each room.

  The vegetable room 400 is cooled by circulating the return cold air from the refrigerating room 100 from the return air passage for the refrigerating room, and then returned to the cooler 3 from the return air path for the vegetable room. The temperature of each room is detected by a thermistor (not shown) which is a temperature detecting means installed in each room. Basically, the output of the compressor 10 and the amount of air blown from the blower fan 2 are adjusted based on the output of the thermistor in the freezer compartment 300, and the other airflow is set in the blower air passage 4 so that the other rooms have a preset temperature. It is controlled by changing the opening of a damper (not shown) installed. However, when the room other than the freezer compartment 300 has a very high load, for example, when quick freezing is set, the compressor 10 and the blower fan 2 operate according to the control, and the temperature of the freezer compartment 300 also changes the damper opening. Controlled by

  The cooling dish 7 for manufacturing the ice confectionery that is an object to be cooled can be installed in the vibration applying device 8 installed in the switching chamber 200 in advance. In the vibration applying device 8, for example, a pendulum motor drives a portion on which the cooling tray 7 is placed, but is not limited thereto. Note that the vibration applying device 8 may be installed anywhere as long as it is in a freezing temperature zone, or may be provided in the freezing room 300 or the ice making room 500. Here, the switching chamber 200, the freezing chamber 300, or the ice making chamber 500 in which the cooling tray 7 and the vibration applying device 8 are installed are collectively referred to as “cooling chamber”. The operation of the vibration imparting device 8 is started when the refrigerator user presses, for example, an “ice cream” button on the ice confectionery menu provided on the operation panel 5. Reference numeral 11 denotes a temperature sensor for detecting the temperature of the ice confectionery raw material 9 such as a thermistor installed in the vibration applying device 8. The detected temperature of the temperature sensor 11 is compared with a preset temperature set on a control board (not shown). By doing so, the operation of the vibration applying device 8 is controlled.

  Next, the structure of the cooling tray 7 and the vibration imparting device 8 and the operation when generating ice confectionery will be described with reference to FIGS. FIG. 2 is a control flowchart of the vibration applying device, FIG. 3 is a schematic diagram showing the cooling dish, the vibration applying device, and their operation, and FIG. 4 is for rotating the ice confectionery raw material from semisolid to solid in one direction. It is an enlarged view of the hemispherical hollow part of the cooling tray which shows one Example of this structure.

As shown in FIG. 3, the cooling dish 7 has a configuration in which one or a plurality of hemispherical depressions 7 a are formed on a box-shaped bottom surface.
The vibration applying device 8 is configured to move one end portion of the mounting plate 8a up and down by a pendulum motor 8b via a lever 8c.

  Referring to FIG. 2, first, the power source of the refrigerator body 1 is turned on, and in step 1, the compressor 10 and the blower fan 2 are turned on. At this time, the damper connected to each room opens and closes to reach the set temperature of each room based on the output of the thermistor which is a temperature sensor provided in each room as described above. At this time, the vibration applying device 8 is stopped.

  Next, in order for the refrigerator user to produce ice cream ice confectionery, for example, the ice confectionery raw material 9 is put into the cooling dish 7 and the cooling dish 7 is installed on the vibration applying device 8 installed in the switching chamber 200. To do. Thereafter, in step 2, the “ice cream” button on the operation panel 5 is pressed. Here, an “ice cream” display is lit on the liquid crystal screen of the operation panel 5 to inform the refrigerator user that the ice confectionery manufacturing process has started. This transmission means may be another means such as LED lamp lighting or buzzer sound.

  In Step 3, the temperature Ti detected by the temperature sensor 11 for detecting the temperature of the ice confectionery raw material 9 is detected over time, and it is assumed that the ice confectionery raw material 9 preset on a control board (not shown) has started to freeze. It is determined whether or not the temperature has become equal to or lower than a set temperature Tset_1 (for example, 0 ° C.). When Ti becomes lower than Tset_1, the process proceeds to step 4 and the vibration applying device 8 starts operating.

  In step 4, the vibration applying device 8 starts to operate with the vibration pattern 1 shown in FIG. 3. As shown to (a) of FIG. 3, the site | part which mounted the cooling pan 7 of the vibration provision apparatus 8 is initially horizontal. Next, as shown to (b), the one close | similar to the drive part of the vibration provision apparatus 8 goes up, and the ice confectionery raw material 9 in the cooling tray 7 flows to the low side of the cooling tray 7. FIG. Next, as shown in (c), the one closer to the drive unit of the vibration applying device 8 is lowered, and the ice confectionery raw material 9 in the cooling dish 7 is placed on the lower side of the cooling dish 7 (reverse to the time of the operation (b)). Direction).

  By repeating this operation, the ice confectionery raw material 9 is cooled while being sufficiently stirred, and the freezing proceeds. Freezing starts around the ice confectionery material 9. That is, the upper surface of the cooling dish 7 or the inner surface of the cooling dish 7. The ice crystals are peeled off by vibration and mixed well with the unfrozen portion of the ice confectionery raw material 9, thereby suppressing the enlargement and bias of the ice crystals and obtaining an ice confection with a smoother texture. Further, as shown in FIG. 3 (d), the flow path connecting the semispherical depressions 7a so that the ice confectionery raw material 9 in the cooling dish 7 flows and is stirred as much as possible before moving to the next step. 7b may be provided.

  If the above movement occurs in the cooling dish 7, the cooling dish 7 may be moved back and forth or left and right in a horizontal state. Further, in order to promote the peeling of the ice crystals generated on the inner surface of the cooling plate 7, the cooling plate 7 is moved so as to fall freely so as to give a striking vibration to the cooling plate 7 when the cooling plate 7 is lifted and returned to the horizontal state. Also good.

  Next, at step 5, the temperature Ti detected by the temperature sensor 11 for detecting the temperature of the ice confectionery raw material 9 is detected over time, and ice crystals are uniformly formed in the ice confectionery raw material 9 preset on a control board (not shown). It is determined whether or not the temperature has become lower than the second set temperature Tset_2 (for example, −3 ° C.) that is assumed to have become a semi-solid with a hardness of about the soft cream due to a decrease in fluidity. When Ti becomes lower than Tset_2, the process proceeds to step 6 and the vibration applying device 8 proceeds to the next operation.

  In step 6, the vibration applying device 8 moves to the operation of the vibration pattern 2. This is a process for shaping the ice confectionery raw material 9 that has become semi-solid into a spherical shape, and as shown in FIG. 4A, the ice confectionery raw material 9 that has become semi-solid has a spherical shape. Give rotation in only one direction. At this time, as shown in FIG. 4B, this step is performed on the surface of the hemispherical depression 7a so that the ice confectionery raw material 9 rotates only in one direction from the bottom surface to the side surface of the cooling dish 7. A sawtooth-shaped protrusion 7c whose convex portion is inclined in a certain direction from the side surface to the bottom surface is provided so as to go in the rotation direction. As a result, the ice confectionery raw material 9 is rotated only in the same direction as the direction of the protrusion 7c by vibration.

  In Step 7, the temperature Ti detected by the temperature sensor 11 for detecting the temperature of the ice confectionery raw material 9 is detected over time, and the ice crystals are more uniformly formed in the ice confectionery raw material 9 preset on a control board (not shown). It is determined whether or not the temperature has become lower than or equal to a third set temperature Tset_3 (for example, −9 ° C.) that is assumed to be increased and completely solid like a normal ice cream. When Ti becomes lower than Tset_3, the process proceeds to step 8, and the vibration applying device 8 proceeds to the next operation.

  In step 8, the vibration applying device 8 stops operating. The “ice cream” display on the liquid crystal screen of the operation panel 5 is turned off, and the refrigerator user is informed that the ice confectionery manufacturing process has been completed. Note that this transmission means may be another means such as LED lamp blinking / extinguishing or buzzer sound.

  As described above, according to the first embodiment, the bottom surface has a hemispherical indentation part, and includes a cooling tray that stores a liquid or liquid material of a material to be cooled, a freezing chamber that cools the cooling tray, and the like. Since it is a refrigerator that includes a cooling chamber and a vibration imparting device that is installed in the cooling chamber and imparts vibration to the cooling dish, the ice cream stored in the cooling dish or a sherbet-like liquid serving as an ice confectionery raw material is frozen while stirring. Then, since it is shaped into a spherical shape when it becomes semi-solid, it is possible to provide a refrigerator that can make ice confectionery with a good texture and good texture using raw materials without waste.

Embodiment 2. FIG.
FIG. 5 is a schematic diagram showing the cooling tray 7 and the vibration applying device 8A and their operations in the second embodiment of the present invention.
In the present embodiment, in step 4 described above, the vibration applying device 8A is configured so as to give the ice confectionery raw material 9 a vibration pattern of another form. In addition, the structure of the cooling tray 7 is the same as that of Embodiment 1, and the procedure of the control flowchart of FIG. 2 is also the same. In the following, differences from the first embodiment will be mainly described.
As shown in FIGS. 5A and 5B, the vibration applying device 8A has individual curved portions 8d in which the hemispherical recessed portions 7a of the cooling dish 7 can respectively fit, and a magnet stirrer is provided below the curved portions 8d. And a rotating element 8e such as an eccentric motor or an ultrasonic transmitter.

  In step 4, the vibration applying device 8A starts the operation with the vibration pattern 1 shown in FIG. As shown to (a) of FIG. 5, when the vibration provision apparatus 8A is not operate | moving, the surface of the ice confectionery raw material 9 is flat. Next, when the vibration applying device 8 </ b> A starts to operate, as shown in (b), a tornado-like rotation is generated inside each hemispherical recess 7 a of the cooling dish 7. At this time, if the rotation is only in one direction, ice crystals generated in the cooling dish 7 may be fixed to the cooling dish 7, so that the rotation is appropriately clockwise and counterclockwise as shown in (c) and (d). Repeat around. Note that this rotation is not necessarily limited to the horizontal direction, and the agitation may be further improved by adding rotation in the vertical direction as in recent washing machines. Further, as shown in FIGS. 5 (c) and 5 (d), each hemispherical indentation portion is used so that the ice confectionery raw material 9 in the cooling dish 7 is circulated and stirred as much as possible before moving to the next step 5. A flow path 7b for connecting 7a may be provided. This suppresses the generation of dead water areas.

Hereinafter, another means common to the first and second embodiments will be described regardless of the operation of the vibration applying devices 8 and 8A.
By applying a member having high water repellency to the surface of the cooling dish 7, the ice confectionery raw material 9 may be prevented from adhering to the cooling dish 7 when it is in a liquid state and circulation may be promoted.

  Moreover, you may devise the ice which peels easily, such as polishing the inner surface of the cooling tray 7 and making it mirror-like. As a result, the ice crystals generated in the ice confectionery material 9 can be peeled off without adhering to the cooling dish 7 and mixed with the liquid ice confectionery material 9.

  Moreover, you may determine the vibration provision apparatuses 8 and 8A from the difference of the temperature change amount in the fixed time of the temperature detection means 11 of the ice confectionery raw material 9. FIG. For example, when the detected temperature change amount becomes equal to or less than a first temperature change amount (for example, 0.1 K / min), it is assumed that the ice confectionery raw material 9 in the cooling dish 7 has started to freeze, and the vibration pattern 1 is turned on. When the temperature change amount exceeds (for example, 0.1 K / min), it is regarded as a semi-solid state and switched to vibration pattern 2, and when the temperature change amount exceeds (for example, 0.5 K / min), it is completely Vibration may be turned off as frozen.

  Further, the vibration applying devices 8 and 8A may set the vibration pattern switching timing and the on / off timing according to the time counted by a timer (not shown).

  Further, the temperature detection means 11 of the ice confectionery raw material 9 is a thermistor provided so as to be in contact with the cooling dish 7, but may be a non-contact infrared sensor or electric field sensor provided on the ceiling surface of the switching chamber 200 or the like. Thereby, the error factor by the adhesiveness etc. of the temperature detection means 11 and the cooling tray 7 can be reduced, and the temperature of the ice confectionery raw material 9 can be detected stably.

  Alternatively, the temperature may be controlled so that the ice confectionery raw material charged in the cooling tray 7 is once supercooled and then frozen in the vibration process. Thereby, ice confectionery with more uniform and fine ice crystals can be generated.

  Further, the ice confectionery raw material 9 may be anything other than the liquid as described above, as long as it is semi-solid (for example, yogurt) and has fluidity and freezes.

  Further, ice confectionery or ice may be automatically stored in an ice storage box in combination with an automatic ice making device. Thereby, the refrigerator user can use the ice confection shaped as much as he wants whenever he wants.

  Further, water may be frozen in the cooling tray 7. In this case, since the gas component dissolved in water by the effect of vibration and discharged from the ice crystals by freezing is degassed or accumulated to form large bubbles, ice having high transparency and excellent design can be obtained.

  As described above, according to the second embodiment, ice confectionery such as ice cream and sherbet can be automatically made using a refrigerator as in the first embodiment, and the design has a good texture. Can make ice confectionery excellent.
