Description

  The present invention relates to a refrigerator having a space that can store warm food or the like in a freezer temperature zone and can arbitrarily set a temperature zone.

  In recent years, the time that can be spent on household chores at home has been decreasing due to an increase in women's social advancement. In addition, the concept that housekeeping is only done by women has also been reduced, and there are opportunities for men and children to help with housework. For this reason, pre-cooked prepared food can be eaten immediately after it has been thawed by the person who wants to eat it, thus reducing the usual cooking time and labor. In addition, since the growth of bacteria stops at a freezing temperature range of -10 ° C. or lower, it can be stored with peace of mind in terms of hygiene and rot. For these reasons, opportunities to store frozen foods are increasing. Among them, the freezing of rice has become particularly popular recently, and according to a survey, more than 80% of household freezing rooms have frozen rice wrapped in wraps or containers. However, the temperature of cooked or warm-cooked rice wrapped in wrap is about 80 ° C, and it is common to freeze it at room temperature for at least 80 minutes before it enters the freezer and at least until the temperature of the rice reaches room temperature. Met.

  As a conventional refrigerator that solves the above-described general refrigeration method, a refrigerator that is provided with a case having a cold storage tray having a cold storage body in a quenching chamber to perform freezing has been proposed (for example, see Patent Document 1).

Cold air is directly blown into the cooling unit 22 from the cold air vent 28.

  The refrigeration cycle includes a compressor 29, a side condenser 30, and a capillary tube 31.

  The heat insulating material 32 is a vacuum heat insulating material, and since it has flexibility, even if the shape of the cooling unit 22 is flat, uneven, or curved, it can be molded accordingly. It is. Moreover, the heat insulation in the cooling unit 22 improves by using a vacuum heat insulating material, Furthermore, the cooling unit 22 can be thinned rather than using a normal heat insulating material, and the internal space of the freezer compartment 21 is ensured more widely. It is possible. Moreover, since aluminum is configured as the outermost layer film of the vacuum insulation material, it is possible to omit the work of attaching a sheet-like or tape-like material on the surface of the vacuum insulation material, which improves productivity. Is possible. Moreover, since it is configured as the outermost layer film of the jacket material, the number of parts can be reduced. Moreover, it is possible to improve the flame retardance in a vacuum heat insulating material single-piece | unit.

  In addition, since the vacuum heat insulating material is applied to an area of 30% or more of the pastable area of the cooling unit 22, the cooling unit 22 can be highly insulated, and the temperature of the space in the freezer compartment 21 can be increased. It is possible to suppress and keep food in good condition.

  The regenerator 33 has a thickness of 2.0 mm to 7.0 mm, for example, about 5 mm. In place of the cool storage agent, a metal having the same heat capacity as the cool storage agent, such as aluminum or stainless steel, may be used.

  When the cooling unit 22 is installed on the top surface of the freezer compartment 21, the top surface of the freezer compartment 21 comes into close contact with the cooling unit 22 and can be used as a lid of the cooling unit 22.

  A food item 35 or the like is placed on the aluminum plate 34. A temperature detecting means 36 is provided on the top of the cooling unit 22.

  In FIG. 4, the operation panel 24 has a temperature setting means 37 and a temperature display means 38 so that the current temperature in the space 22 can be confirmed and the freezing end temperature of the food 35 or the like stored in the space 22. And storage temperature can be set freely. A cooling cooking menu button 39 is provided on the operation panel 24, and cooling cooking such as “hot frozen rice cake”, “handmade ice cream”, and “boiled vegetable cooling / frozen” can be selected.

  In addition, the end temperature is set for each cooling cooking according to each purpose, and the inside temperature is automatically held at the target temperature when the cooling is completed to the target temperature.

  The compressor 29 and the blower 26 are controlled to the set temperature based on the temperature of the food 35 or the like by the temperature detection means 36 and the information of the temperature setting means 37 and the temperature display means 38.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The refrigerator 29, the vegetable room 19, the switching room 20, and the freezer room 21 are operated by the compressor 29, the side condenser 30, the capillary tube 31, the cooler 25, the blower 26, and the air path control means 27 that constitute the refrigeration cycle. It is cooled to a predetermined temperature.

  When the cooling cooking menu button 39 on the operation panel 24 is selected, the compressor 29 operates at a high speed and the blower 26 operates at a high speed, and a large amount of air is forced into the space 22 from the cold air vent 28 by the air path control means 27. The food or the like 35 placed in the space 22 is rapidly cooled or rapidly frozen by blowing cool air. The temperature of the food etc. 35 is detected by the temperature detecting means 36. When the temperature of the food etc. 35 reaches the target temperature, the forced cooling is terminated and the inside temperature is kept at the target temperature. Is operated while being controlled.

  For example, if the cooked rice is to be quickly frozen, the cooked rice is warm at around 80 ° C., so the hot rice 35 is stored in the space 22 and “Hot Steamed Rice” is selected with the cooling cooking menu button 39 on the operation panel 24. When selected, a large amount of cold air is sent from the cold air vent 28 to quickly cool the warm rice 35, and the temperature of the warm rice 35 is quickly transmitted to the cold storage agent 33 by the aluminum plate 34, and is cooled by the direct cooling action by the cold storage agent 33. The At this time, the product temperature of the warm rice 35 is detected by the temperature detection means 36, and is forcibly cooled until the product temperature of the warm rice 35 becomes -18 ° C or lower. Moreover, even if the heat storage agent 33 cannot take heat away and the temperature in the space 22 rises, the heat insulating material 32 suppresses the temperature rise in the freezer compartment 21. As shown by the solid line in FIG. 5, the temperature of the warm rice at this time is about 90 ° C., reaches 0 ° C. after about 40 minutes at a cooling rate of 2 ° C./minute, and reaches about 0.25 ° C./minute. The temperature reached −5 ° C. after about 60 minutes at the freezing rate, and reached −20 ° C. after about 80 minutes.

  Next, the difference between the food frozen by the conventional freezing method and the food frozen by the freezing method of the first embodiment will be described.

  Conventionally, when warm food is stored, the temperature in the freezer compartment 21 rises and adversely affects the frozen food already stored, so the warm food is not immediately put into the freezer. For this reason, when freezing hot rice, it has been necessary to cool the hot rice until it reaches room temperature and then put it in the freezer. As shown in the practice of FIG. 6, the temperature of the hot rice at that time reaches an initial temperature of about 90 ° C. and reaches about 25 ° C. after about 160 minutes, puts it in the freezer compartment 21, and cools at a rate of 0.4 ° C./min. The temperature reached 0 ° C. after about 180 minutes, reached −5 ° C. after about 280 minutes at a freezing rate of about 0.05 ° C./minute, and reached −20 ° C. after about 350 minutes.

  In such a conventional method, since it takes about 160 minutes to cool down to a room temperature that can be put in the freezer room, the housework time becomes longer, so that it is forgotten or the subsequent work remains. There were issues such as being mentally uncomfortable and being restrained.

  In addition, while the rice is slowly cooled, the water in the rice evaporates, and the texture of the rice deteriorates due to the drying of the surface portion, and deterioration such as wrinkles on the appearance is observed. In addition, since the time during which the rice is exposed to a high temperature becomes longer, deterioration such as yellowing of the rice due to the aminocarbonyl reaction is also observed.

  Also, when frozen, if the passing speed of the maximum ice crystal formation zone from 0 ° C to -5 ° C is slow, the volume of ice crystals formed in the food will increase and the cell membrane and cell wall will break, causing cell destruction and thawing However, there is a problem that the texture does not become elastic at the time, or the moisture inside the broken cells flows out to increase the amount of drip and the texture becomes worse.

  Further, in the above-described conventional configuration, a quick freezing of warm food is proposed in an independent switching room 3, but this switching room 3 is not only a soft freezing room and a freezing room, but also a wine room, a vegetable / refrigeration room, a chilled room. It can be switched to a room. For this reason, for example, when wine is set in a wine room, vegetable / refrigerated room, chilled room, etc. and used for storing wine, vegetables, chilled food, etc., these stored foods are stored in other refrigerated rooms, vegetable rooms, etc. If you do not put warm food in the switching room after moving to a room suitable for food, if the stored food freezes, there will be dangers such as broken bottles and wasteful disposal due to freeze degeneration of vegetables, etc. It had the problem of end.

  Even when the soft freezing room and the freezing room are set, the switching room is a room used for storing and storing food. When food is stored, new food is placed on the surface of the cold storage tray 3b. In many cases, there is no space for storage, and when hot food is newly placed and quickly frozen, the temperature of the surrounding food rises, causing problems such as quality degradation due to temporary thawing. It was.

  Compared with these conventional refrigeration methods, according to the refrigeration method of the first embodiment, even if warm food is put in the cooling unit 22, there is very little adverse effect on the frozen food in the freezer compartment 21. The freshly cooked warm rice can be immediately put into the cooling unit 22 of the freezer. Moreover, since the cooling unit 22 is provided with the cold air vent 28 on the side facing the duct 128 on the top surface of the freezer compartment 21, only the inside of the cooling unit 22 can be rapidly frozen. By rapidly freezing warm rice as it is, quality deterioration such as yellowing of rice can be prevented, and delicious frozen food can be provided.

  Therefore, in the method shown in the present embodiment, compared to the conventional freezing of rice, the same deliciousness as freshly cooked can be obtained even after thawing, and there is a significant reduction in housework.

  In addition, warm food can be kept at an arbitrary set temperature after being rapidly cooled or frozen, so that the food is provided in a quality state and at the optimum temperature for each purpose such as the temperature at which it is eaten. It became possible.

  In the case where the warm food is freshly cooked rice, for example, the electricity bill can be greatly reduced as compared to the case where the jar cooked in the evening is kept warm until morning. In addition, since the evaporation of moisture that occurs during the process of cooling the temperature of the rice is suppressed, it is possible to reproduce the deliciousness of the freshly cooked rice that is plump when thawed.

  Further, when “handmade ice cream” of the cooling cooking menu button 39 is selected, an ice cream or a sherbet that has been troublesome in the freezer compartment 21 can be easily made. For example, the ingredients such as milk, whipped cream, sugar, eggs, etc. heated and heated while being melted with sugar, put in a pudding cup etc. are put in the space 22 and the cooling cooking menu button on the operation panel 24 When “handmade ice cream” is selected at 39, a large amount of cold air is sent from the cold air vent 28 to rapidly cool the ice cream 35 put in the pudding cup, and the temperature of the ice cream 35 is quickly increased by the aluminum plate 34 to the cold storage agent 33. And is cooled by the direct cooling action by the cold storage agent 33. The initial temperature of the stock ice cream solution is about 60 ° C., but it can be quickly put into the space.

  At this time, the product temperature of the ice cream 35 is detected by the temperature detecting means 36, and the ice cream 35 is forcibly cooled until the product temperature of the ice cream 35 is equal to or less than −12 ° C., which is the temperature around eating. Ice cream can be eaten deliciously at -12 ° C with good hardness. When the temperature detecting means 36 detects that the product temperature of the ice cream 35 is −12 ° C., the forced cooling is finished, and the fact that the ice cream has been made is displayed by a method such as displaying an alarm sound or a display panel. I will inform you.

  As a result, you can eat delicious homemade ice cream after about 1 hour. For example, if you set up ice cream after you have finished eating lunch, you will have homemade ice cream at the snack time. It is also possible to feed children with delicious homemade ice cream.

  In addition, after the ice cream has been frozen and forced cooling is completed, the space 22 is maintained at -12 ° C, which is the temperature at which ice cream is eaten, so it can be served at any time even if it is not eaten immediately. can do.

  Conventionally, ingredients such as milk, fresh cream, sugar, and eggs are heated and mixed while warming, cool at room temperature, and then put in the freezer. Therefore, it is necessary to take out from the freezer several times and stir, and the creation time of the ice cream is 12 hours or more. If a great effort and time are not spent, the handmade ice cream cannot be made delicious.

  Moreover, since the normal freezer compartment was set to -18 degrees C or less, the product temperature of ice cream became -18 degrees C or less, and it was not able to eat immediately with the tick.

  As a result, the ice cream preparation time can be significantly shortened compared to the conventional method, and the taste is improved.

  Further, the heat insulating material is usually weak to water, and when the moisture is adsorbed, the heat insulating performance is greatly reduced. However, in this embodiment, the core material having the heat insulating performance is sealed as described above. By using the vacuum heat insulating material, it is possible to prevent moisture from entering into the heat insulating material, so that the heat insulating material is not adversely affected by moisture such as moisture in the refrigerated room or frost in the freezer room. Can exhibit excellent heat insulation performance.

  In the present embodiment, the cooling member 130 includes a heat insulating material 32, a cool storage agent 33 placed on the heat insulation material 32, and an aluminum plate 34 placed on the cool storage agent 33. However, the cool storage agent may be covered with an aluminum plate, and this may be adjacent to the heat insulating material. In this case, the cool storage agent and the aluminum plate are integrated so that the set of the cool storage agent and the aluminum plate can be taken out of the refrigerator from the freezer and used as a cooling member for, for example, a pot or food. There is a peculiar effect that can be done.

  In the present embodiment, the cooling member 130 includes a heat insulating material 32, a cool storage agent 33 placed on the heat insulation material 32, and an aluminum plate 34 placed on the cool storage agent 33. However, a heat insulating space may be provided between the heat insulating agent and the cold storage agent, and the heat insulating performance of the cooling member 130 can be further improved through the heat insulating space.

  As described above, the refrigerator according to the present invention suppresses the temperature rise in the freezer compartment outside the space due to the heat insulating effect of the vacuum heat insulating material even if hot food is put in the refrigerator, and the Heat can be conducted with a plate made of a material with good thermal conductivity, and the heat can be quickly taken away by a cold storage agent, so that the temperature inside the cabinet is suppressed, so that the quality of the stored food can be maintained. Therefore, this technology can be applied to any refrigeration equipment and heat insulation equipment other than the refrigerator, and can be applied to, for example, creating several types of temperature zones different from the surrounding room temperature in the system kitchen.
