Description

  The present invention relates to a refrigerator with an ice making device for home use provided with an ice making device for automatically producing transparent ice.

  Many proposals have been made in the past for producing transparent ice in an automatic ice making apparatus incorporated in a home refrigerator. For example, by installing a heating plate on the top of an ice making container of an automatic ice making device and warming the water on the ice making container (ice tray), the freezing rate is slower than the diffusion rate of dissolved gases such as impurities and air contained in the water. Make ice with high transparency. That is, a portion of the water is heated to partially delay freezing without simultaneously freezing the entire water. Thereby, the gas and impurities dissolved in the water move and diffuse from the frozen water into the heated water. As a result, the ice made becomes highly transparent ice. However, the portion where the dissolved gas and impurities are concentrated and frozen is naturally less transparent. This example is shown in Patent Document 1.

  On the other hand, as recently proposed, an ice making evaporator dedicated to an ice tray is provided in the refrigerator, and water is circulated through the ice making section cooled by the ice making evaporator, so that pure water is solidified (freezing first). ) And making clear ice without impurities. This example is shown in Patent Document 2.

Japanese Patent Laid-Open No. 1-123968 JP 2006-317077 A

  The conventional ice making device disclosed in Patent Document 1 warms up the water temperature in the ice making container (ice tray) to increase the freezing speed, so that the time required for completing ice making compared to freezing without increasing the water temperature. Becomes extremely long (slow). Therefore, when trying to make transparent ice in a household refrigerator, there is a problem that it takes 8 to 10 hours while the conventional ice making time is 1 to 2 hours. Moreover, this kind of refrigerator is cooled by the evaporator of the refrigerating cycle which connected the compressor-condenser-decompressor-evaporator in order. That is, the cold air heat-exchanged by the evaporator is forcibly circulated to each room, thereby cooling the freezer room, the refrigerator room, the vegetable room, etc. to the set temperature.

  Moreover, the refrigerator-freezer shown by patent document 2 provided the evaporator for ice making which can vaporize a refrigerant | coolant in parallel with the previous evaporator other than the evaporator of the refrigerating cycle which the said refrigerator-freezer has. Is. Then, a refrigerant circulating in the refrigeration cycle is passed through the ice making evaporator, and the heat of vaporization is transmitted to water via the ice making evaporator. That is, this refrigerator-freezer directly cools water with an ice making evaporator without interposing air with low thermal conductivity. By carrying out like this, this freezer refrigerator makes a separate freezing cycle etc. unnecessary, it aims at aiming at shortening of ice making time besides suppressing enlargement of freezer refrigerator itself.

  Further, pure water is preferentially frozen in the cooling unit by blowing ice-making water to the cooling unit fixed to the ice-making evaporator, or by flowing ice-making water, so that impurities are contained in water and collected, and transparent. Techniques aimed at making ice are disclosed. In this case, it is not necessary to provide a separate refrigeration cycle having an ice making evaporator, so that the size of the refrigerator itself can be suppressed and the ice making time can be shortened, and transparent ice can be obtained.

  However, in Patent Document 2, the ice making room is divided into an ice making room and an ice making storage room, the ice making room is adjusted to a temperature in a refrigeration temperature zone of 0 ° C. to 5 ° C., and the ice making storage room has a freezing temperature zone of −20 ° C. Although it is supposed to be adjusted to the temperature, it is not clearly shown by what means the ice making chamber is divided into an ice making chamber of 0 ° C. to 5 ° C. and an ice making storage chamber of −20 ° C. In other words, nothing is described about the detailed structure of a damper blade or the like that thermally blocks an ice transfer hole provided in a partition heat insulating wall or the like that partitions the ice making and ice storage chamber.

  Furthermore, although the ice-freezing chamber is maintained at a temperature of 0 ° C. to 5 ° C. in the refrigerator compartment, it is not specified what kind of positional relationship it is with the refrigerator compartment. In a refrigerator with an ice making device that circulates water to the ice making plate to make sheep-like transparent ice, the ice making plate is heated, and the resulting ice is dropped from the ice making plate and transferred to the ice cutting part, where heat rays, etc. After using ice to cut small pieces of ice, it is stored in an ice storage container in the freezer compartment. There was a problem that the ice melted partially because it heated the ice that could be said to be temporary. Moreover, although it was for cutting ice in a refrigerator, since the cord heater generated heat, it was not the best from the viewpoint of energy saving. Furthermore, since the ice cutting part must be prepared inside the refrigerator, there is a problem that the narrow refrigerator is further narrowed.

  In a refrigerator with an ice making device that circulates water to an ice making plate to make a yolk-shaped transparent ice, the ice making plate is heated, and the resulting ice is dropped from the ice making plate and transferred to an ice cutting section where it is heated. After being cut into small pieces, etc., it is stored in an ice storage container in the freezer compartment. For this reason, although the said ice-making board and ice were heated even temporarily, there existed a problem that ice melted out partially. Further, although it is for cutting ice in the ice making and freezing chamber 22a, it is not the best from the viewpoint of energy saving because the cord heater generates heat. Furthermore, since the ice cutting part must be prepared inside the refrigerator, there is a problem that the inside of the narrow refrigerator is further complicated.

  The present invention has been made to solve the above problems.

  That is, in a refrigerator having a refrigerator compartment, a freezer compartment, a vegetable compartment, etc., and having a dedicated cooler in the ice making unit, circulating water to the ice making cooler to make transparent ice, A connecting passage through which ice passes is formed in the partition insulation wall that divides the refrigerator compartment and the ice storage compartment up and down, and a damper blade for controlling the ice falling at the exit of the connecting passage is provided and falls into the ice storage container. A transparent portion made by the ice making unit by using a refrigerator with an ice making device provided with a flexible part that prevents the ice block from being locked by being lifted by the blade and sandwiched between the blade and the outlet. The ice storage room can be stored for a long time without melting the ice at the refrigerator temperature. In addition, since the blade is not designed to entrain the ice in the ice storage container when the blade rotates, for example, the blade rotation trajectory is designed within the height of the ice storage container. It can be a refrigerator filled with height dimensions. Therefore, an efficient refrigerator capable of reducing the distance between the blade and the ice storage container can be provided.

  Also, an ice making device in which the blade that closes the communication path through which the ice passes is divided into two, and a double-spreading system is provided, and a packing made of a flexible member is provided at the tip of both blades, and the joint is sealed with the packing By making the refrigerator with a refrigerator, the rotation trajectory of the damper blade can be made small, the height dimension of the ice making chamber into which the ice storage container is placed can be made small, and of course, the refrigerator with an efficient ice making device can be made. There is no need to worry about ice being involved due to the small height dimension of the blade, and since there is a flexible member between the blades, the gap between the joints can be eliminated and the ice making device without locking etc. An attached refrigerator is obtained.

  In addition, since the blade that closes the communication path through which ice passes is provided at two places, the entrance and exit of the hole through which ice passes, and a flexible member is provided at the tip of the blade, the sealing performance of the communication path through which ice passes is provided. As a matter of course, it is possible to obtain a refrigerator with an ice making device in which foreign matter accumulates in the communication path through which ice passes and does not lock.

  In addition, the ice and the blade are not obstructed by the ribs and do not come into surface contact while being collected at the outlet by providing a refrigerator with an ice making device provided with a rib that drops ice on the slope from the blade. When the blade rotates, the ice falls into the container under its own weight. Therefore, it is possible to obtain a refrigerator with an ice making device in which the ice does not interfere with the next blade closing stage and the outlet cannot be sealed. Furthermore, the ice is guided by the ribs, so that the ice does not easily stay on the blade.

  In addition, an inclined surface is provided on the rear wall surface of the ice storage container to guide the ice falling through the blade to the center side of the ice storage container, and the ice stored in the ice storage container is stored in the ice storage container so that the ice does not touch the blade. By making a refrigerator with an ice making device that secures the H1 dimension between the amount of the blade and the lower end P of the blade at the time of rotation, it is possible to prevent the entrainment of ice at the time of blade rotation, and the ice in the center of the ice storage container Since it can be kept in hand, it becomes a refrigerator with an ice making device that is convenient for the user.

  In addition, by setting the full ice detection position of the level sensor that controls the amount of ice stored in the ice storage container as a refrigerator with an ice making device that is H1 dimension below the locus where the damper blade opens and closes, the ice stored in the ice storage container Since the blade is not touched, the refrigerator is equipped with an ice making device in which the operation of the damper blade is not disturbed by the accumulated ice.

  Also, in a refrigerator having a refrigerator compartment, a freezer compartment, a vegetable compartment, etc., and having a dedicated cooler in the ice making section, and circulating water in the ice making section to produce sheep-shaped transparent ice on the ice making plate A crushing claw that is displaced by an external force is provided on the ice making plate and within the thickness of the transparent ice, and during crushing, the crushing claw inside the sheep-shaped transparent ice is displaced by an external force, the transparent claw Since ice is crushed, it is not necessary to use a heat wire that heats the inside of the refrigerator. Of course, it is not necessary to make an ice cutting part, so space efficiency is improved and energy saving of the refrigerator is achieved. Can also be achieved. Furthermore, even if there is ice residue in the ice making plate part using this seed crushing method, the ice is once melted during the next water circulation and becomes ice again, so the remaining ice grows in an unusually strange shape. Thus, the ice making function is not impaired.

  In addition, the crushing claw is displaced by the drive motor and the drive motor is installed at a position away from the ice making plate. By not being fixed, the degree of freedom of design is expanded.

  In addition, the crushing claw is directly attached to the shaft of the drive motor, the crushing claw is positioned on the ice making plate, and several crushing claws located on the ice making plate are displaced by the drive motor via the planetary gear, so that the ice The crushing claw can be attached without providing any special means because it is crushed, and of course, the size of the crushed ice can be appropriately changed by combining planetary gears.

  Also, a plurality of crushing claws are provided on the operating plate, and this operating plate is provided on the ice making plate and within the thickness of the transparent ice to be produced, and the crushing claw is displaced when the transparent ice is completed. A relatively stable shape of ice can be obtained.

  The present invention enables long-term storage in an ice storage room without melting the transparent ice produced in the ice making section at the refrigerator temperature. In addition, even if the damper blade provided at the hole exit through which the ice passes may come into contact with the ice in the ice storage container, the blade has been devised so that the ice in the ice storage container does not get caught when the blade rotates. Therefore, there is no problem even if the design is such that the rotation trajectory of the blade enters the height of the ice storage container. Therefore, it is possible to provide a refrigerator capable of reducing the distance between the blade and the ice storage container.

  In addition, the present invention eliminates the need to use a heat wire or the like that heats the inside of the refrigerator as in the prior art to pulverize the resulting ice. In addition, energy saving in the refrigerator can be achieved. In addition, even if there is ice residue on the ice making plate using this seed crushing method, the ice is once melted during the next water circulation and becomes ice again, so the remaining ice grows in an unusually strange shape. And it can be set as the refrigerator which does not say that the ice making function is impaired.

  Embodiments of the present invention will be described with reference to the drawings.

  1 to 4, reference numeral 1 denotes a refrigerator-freezer body having a freezer compartment, a refrigerator compartment, a vegetable compartment, an ice storage compartment, and the like. As shown in FIG. And an ice storage room 3, a freezing room 4, and a vegetable room 5. 6 to 9 are doors for closing the front openings of the respective chambers. Reference numeral 6 denotes a refrigerator compartment door that rotates around a hinge (not shown), and the other 7 to 9 are drawer type doors. When the drawer type doors 6 to 9 are pulled out, the containers constituting each chamber are pulled out together with the doors. 7 is an ice storage room door, 8 is a freezing room door, and 9 is a vegetable room door. 11 is a packing which seals between the doors 6-9 and the box body of the refrigerator-freezer main body 1, and is attached to the indoor side outer periphery of each door 6-9. A partition heat insulating wall 12 partitions and insulates between the refrigerator compartment 2 and the ice storage chamber 3. The partition heat insulating wall 12 is about 30 to 50 mm thick and is made of foam heat insulating material such as styrofoam or urethane foam, vacuum heat insulating material or the like. 13 is a partition heat insulation wall that partitions and insulates between the ice storage room 3 and the freezer room 4 and the vegetable room 5, and has a thickness of about 30 to 50 mm like the partition heat insulation wall 12. This is also made of foam insulation such as styrofoam or urethane foam, vacuum insulation and the like.

  Next, the refrigeration cycle provided in the refrigerator main body 1 will be described with reference to FIGS. In the figure, 16 is a compressor, 17 is a first cooler for cooling the refrigerator main body 1, and 18 is a cooler for ice making (shown in FIG. 4). The refrigerant gas compressed by the compressor 16 is condensed and liquefied by a condenser (not shown), depressurized by the depressurizer, and the depressurized liquid refrigerant evaporates by the first and second coolers and returns to the compressor. Reference numeral 19 denotes a blower provided near the first cooler 17. The blower 19 exchanges heat with the previous cooler 17 and blows the dehumidified cold air to the freezer compartment 4, the refrigerator compartment 2, the vegetable compartment 5 and the like through a supply duct (not shown). The cold air supplied by the supply duct is collected by a return duct (not shown). At this time, the circulating air that exchanges heat with the cooler 17 is cooled by the cooler 17 and deprived of moisture. Therefore, a large amount of frost is attached to the cooler 17. The defrosting heater 20 periodically removes the frost.

  In the case of the present embodiment, the ice making cooler 18 mainly cools the ice making portion 21 for making transparent ice. The method of flowing the refrigerant to the ice making cooler 18 and the first cooler 17 is as shown in FIG. This will be explained later. Next, the ice making device main body 10 of the present invention will be described with reference to FIGS. Note that the ice making apparatus main body 10 mentioned here refers to a place excluding a portion for storing ice that includes the ice making unit 21. Next, in FIG. 2 and FIG. 3, the water storage tank 22 for storing the circulating water and the ice making apparatus main body 10 which receives the circulating water and freezes the circulating water on an ice making plate to form a transparent ice block have been produced. A function in the middle of stocking ice blocks in an ice storage container 30 provided in the ice storage chamber 3 will be described. Reference numeral 22 denotes a water storage tank. The water storage tank 22 is an ice making chamber formed between the lowermost stage of the refrigerator compartment 2 (the upper surface 12a of the partition heat insulating wall 12) and the shelf board 14 as can be seen from FIGS. 15 is provided as shown in the figure.

  As can be seen from FIG. 3, the depth dimension of the ice making chamber 15 extends from the position avoiding the depth dimension L1 of the pocket 6 a of the refrigerator compartment door 6 to the back wall 2 a of the refrigerator compartment 2. Further, as shown in FIG. 2, the width of the ice making chamber 15 is almost ½ of the width of the refrigerator compartment. This is because the refrigerator compartment door 6 is aligned with the door vertically divided into two at the center. In the ice making chamber 15, the water storage tank 22 is installed as shown in FIGS. 2 to 3. Usually, the water storage tank 22 is formed in a tank capable of storing about 1 to 2 L of water. This 1 to 2 L of water is the amount of water used by the ice making device in one day. Accordingly, when the user confirms that there is no water in the water storage tank 22, the user takes out the water storage tank 22 from the ice making chamber 15 and supplies water. From this point, the conventional water storage tank 22 is installed in a place that is easy for the user to handle.

  In other words, in this embodiment, the water storage tank 22 is provided so as to close the opening of the ice making chamber 15, and the front of the opening is covered. 10 is an ice making device main body, and this ice making device main body 10 is provided side by side with the water storage tank 22. In FIG. 3, it is provided in the ice making chamber 15 and on the back side of the water storage tank 22. That is, the ice making device main body 10 is installed in the ice making chamber 15 in the refrigerator compartment 2. The ice making apparatus main body 10 is installed in an outer case 44 that is separated from the refrigerator compartment 2. Of course, the case 44 has a lid or the like and can be opened and closed. Therefore, when cleaning pipes and the like, the case 44 can be easily removed by removing the lid and the like.

  Next, the ice making device main body 10 installed in the outer case 44 will be described with reference to FIG. In this figure, the water in the water storage tank 22 installed in the refrigerator compartment is once transferred to a metering tank 23 (a tank for storing the amount of water necessary for one ice making), and the water in the metering tank 23 is made into ice. The plate 21 is circulated with a circulation pump 24 to make a plate-shaped transparent ice of a predetermined size (including thickness) in the ice making unit 21, which is divided into a predetermined size by a cut heater 29, and the ice is formed into ice. An ice making device for storing ice by dropping into an ice storage container 30 provided in the storage chamber 3 via a communication path 12a will be described. In addition, since the ice making apparatus main body 10 (ice making part) is installed in the refrigerator compartment 2 side, the atmospheric temperature of this ice making apparatus main body 10 is 0-5 degreeC. Accordingly, the ice blocks formed here are dropped on the side of the ice storage container 30 (the ice storage chamber temperature is −20 ° C.) as the damper 51 is opened as shown in FIG. Further, the ice making device main body 10 plays a role of transporting ice blocks up to a communication path 12 a provided in the partition heat insulating wall 12.

  Here, the damper 51 described above will be described. The blade 51a of the damper 51 always works in a direction to close the connecting passage 12a, and ensures a temperature difference between the ice storage chamber 3 and the refrigerator compartment 2. However, when the cutting of the ice block is completed by the cut heater 29, it works to open the communication path 12a for a predetermined time. Further, the ice making device main body 10 is supplied with water for each time to the metering tank 23 by the water supply pump 26. Hereinafter, these will be described in more detail. Reference numeral 22 denotes a detachable water storage tank installed at the bottom of the refrigerator compartment 2 (upper surface 12b of the partition heat insulating wall). For example, 10 times the amount of water used at one time is stored.

  That is, if the amount of water used at one time in the ice making unit 21 is 200 cc, it has a capacity capable of storing 2000 cc. Further, the water storage tank 22 can be pulled out by removing a connection with a water supply pipe, for example, a water supply pipe for sending water to the metering tank 23, and the inside of the water storage tank 22 can be easily cleaned by opening the lid. It is made in a structure that can be done.

  23 is a metering tank that is detachably installed in the outer case 44. In the metering tank 23, as described above, the amount of water corresponding to one piece of transparent ice made by the ice making unit 21 is stored in the water storage tank 22. Have been transported more. Similarly to the water storage tank 22, the metering tank 23 can be pulled out by removing the connecting portion with the water supply pipe, and the inside can be easily cleaned by opening the lid. The water supply pump 26 transfers water from the water storage tank 22 to the metering tank 23. The water supply pump 26 may be a so-called non-contact type pump in which the drive unit is outside the water storage tank 22 and the pump unit is in the water storage tank 22. The predetermined amount of water is, for example, the amount of water that can be obtained by turning the water supply pump 26 for 10 seconds. In short, it is a structure that ensures a certain amount of operation time by the capacity of the pump.

  Reference numeral 25 denotes a water supply pipe. Although not shown in the drawing, the water supply pipe 25 is detachably connected to the water storage tank 22 and the metering tank 23 at a connecting portion. Accordingly, the water storage tank 22 is devised so that it can be easily removed during water supply or cleaning. A circulation pump 24 circulates water in the metering tank 23 to the ice making unit 21. The circulation pump 24 circulates the water at the top of the ice making plate 21a constituting the ice making part 21 provided at an inclination. Reference numeral 28 denotes a diversion nozzle provided at the tip of the previous water supply pipe 27. The water supply pipe 27 connects between the diversion nozzle 28 and the metering tank 23. The diversion nozzle 28 serves to flow a uniform amount of water over the full width of the ice making plate 21a. Reference numeral 21 denotes an ice making unit. The ice making unit 21 includes, for example, an ice making plate 21a made to have a width of 100 mm, a length of 150 mm, and a height of 30 mm, an ice making cooler 18 that cools to about −10 to −20 ° C., and the like.

  Of course, the ice making plate 21a is made of a thin metal plate having good thermal conductivity such as aluminum or copper, and is attached to the ice making cooler 18 in good thermal condition. For this reason, the ice making plate 21a surface (surface through which water flows) is naturally maintained at a temperature of -20 to -30 ° C. The water flowed from the diversion nozzle 28 to the ice making plate 21a is gradually grown as transparent ice. Water containing impurities that have passed without being made by the ice making plate 21 a is returned from the return port 23 a provided in the previous quantitative tank 23. By repeating this, only the water with less air and impurities is frozen on the ice making plate 21a, and the impurities are returned to the metering tank 23 as unfrozen circulating water. As a result, transparent ice plate is always formed on the ice making plate 21a.

  When the ice making on the ice making plate 21a is completed, the interface between the ice making plate 21a and the ice is melted, and the ice plate 21a is inclined to the cut heater 29 which is the next step, and the ice plate after the ice making is completed is lowered. Let The plate-shaped transparent ice reaching the cut heater 29 is divided into a predetermined size by the cut heater 29, dropped as shown in the figure, and stored in the ice storage container 30. At this time, the cut heater 29 has a heat generation amount that can cut the plate-shaped transparent ice over, for example, about 10 to 60 minutes. That is, if one ice-making cycle is 60 minutes, the plate-like ice may be divided by the cut heater to become block ice within 60 minutes. The ice making part components for making transparent ice, for example, the ice making plate 21a, the metering tank 23, the circulation pump 24, the water supply pipe 27, the diversion nozzle 28, the cut heater 29, etc. are all set to a room temperature of 0 to 5 ° C. It is installed in the outer case 44.

  Thereby, both the water supply pipe 25 and the water supply pump 26 are protected from freezing, and no anti-freezing heater is required. That is, the refrigerating chamber 2 is secured at room temperature by the amount of cool air entering the refrigerating chamber 2 via a cool air amount control damper or the like that has been generally employed. Furthermore, the water storage tank 22 and the metering tank 23 can be taken out of the refrigerator, and the interior can be easily cleaned to replenish water to the water tank 22 or to store the water in the metering tank 23. Impurities can be easily washed away.

  Next, it demonstrates using FIG. FIG. 5 is a diagram for explaining an embodiment different from FIG. In the figure, 2 is a refrigerator compartment, 3 is an ice storage compartment, and 4 is a freezer compartment. Reference numeral 12 denotes a partition heat insulating wall. In this figure, the water storage tank 22 and the ice making apparatus main body 10 are installed in parallel to the ice making chamber 15 as viewed from the front. Also in this case, the same effect as that obtained when both the front and rear sides are provided (FIG. 2) can be obtained.

  Next, the ice making cooler will be described with reference to FIG. In the figure, 16 is a compressor, 31 is a condenser, 33 is a flow switching valve, 17 is a first cooler, 18 is an ice making cooler, and 19 is heat exchange with the first cooler. It is a blower that forcibly circulates the cool air to each chamber. Reference numeral 34 denotes an expansion valve. Reference numeral 35 denotes a control unit. The control unit 35 changes the opening degree of the expansion valve 34, changes the degree of pressure reduction, changes the refrigerant flow direction of the flow path switching valve 33, and stops. For example, when ice making is to be performed only with the ice making cooler 18, the opening of the expansion valve 34 is increased, and when the refrigerant is simultaneously supplied to the coolers 17 and 18, the previous opening is decreased, and only the first cooler 17 is cooled with refrigerant. When flowing, control the temperature by setting the previous opening to an intermediate position. In this way, the embodiment shown in FIG. 6 is that the controller 35 controls the expansion valve 34 and the flow path switching valve 33 so that the refrigerant has an evaporating temperature range and an efficient refrigeration cycle operation can be performed.

  Next, the ice making unit 21 will be described with reference to FIG. FIG. 7 is an enlarged cross-sectional view of the ice making unit 21 used in the present invention. In the figure, reference numeral 21 denotes an ice making unit which comprises an ice making plate 21 a and an ice making cooler 18. Reference numeral 28 denotes a diversion nozzle. Reference numeral 36 denotes a mounting plate for attaching the ice making cooler 18 formed of a pipe 18a bent in a U-shape so as to be in close contact with the ice making plate 21a. Both sides of the mounting plate 36 are made to substantially match the pipe diameter so as to be in close contact with the pipe 18a bent in the U-shape.

  When the ice making cooler 18 is attached to the ice making plate 21a, it is completed by inserting the cooler 18 from the direction of arrow P so as to slide toward the attaching plate 36. In other words, the ice making platen 21a can be attached to the ice making cooler 18 later by allowing the ice making cooler 18 to face the refrigerator compartment at the stage of manufacturing the refrigerator. 37 is a heat insulating material for concentrating the heat of the ice making unit 21 on the ice making plate 21a through which water flows, and 38 is for heating the ice making unit 21 when the transparent ice is completed to melt the interface of the transparent ice attached to the ice making plate 21a. The heater is configured to drop the plate-shaped transparent ice that has been removed from the ice making plate 21a toward the cut heater.

  Next, an example in which the ice making mechanism member of the present invention is unitized into an ice making device main body 10 will be described with reference to FIGS. In the figure, 21 is an ice making section, 21a is an ice making plate, 23 is a metering tank, 24 is a circulation pump, 25 is a water supply pipe, 27 is a water supply pipe, 28 is a diversion nozzle, 29 is a cut heater, 30 is an ice storage container, Reference numeral 36 denotes a mounting plate. The members (21, 21a,...) Constituting the ice making apparatus main body 10 are assembled into a base material (not shown) and unitized. Among the constituent members of the ice making apparatus main body 10, the ice making cooler 18 attached to the ice making plate 21 a is excluded from unitization.

  That is, as shown in FIG. 4, the water supply tank 22 and the water supply pump 26 for supplying water to the metering tank 23 from the water storage tank 22 are often provided on the front side in terms of supply to the water storage tank 22 from the water supply or the like. Therefore, these should be excluded from the unitization target. Further, the ice making cooler 18 attached to the ice making plate 21a has the same refrigeration cycle and refrigerant pipe attached in advance to the refrigerator box side, so that it is also excluded from the unitization.

  Thus, 44 is an outer case for housing the members (21, 21a,...) Constituting the ice making apparatus main body 10 as a unit. The outer case 44 may be a single container or may include a few parts (for example, a lid, a container, and a member to be placed in the outer case 44). In addition, the outer case 44 has a function of blocking dust and the like from entering the circulating water from the inside and outside (outdoor). Reference numeral 44 a denotes a water supply pipe outlet provided in the outer case 44, and the water supply pipe 25 is drawn out of the outer case 44 from the water supply pipe outlet 44 a. The water supply pipe 25 drawn out from the water supply pipe outlet 44a is connected to a connection portion 25a of the water supply pipe 25 coming out from the water storage tank 22 side.

  44b is an ice making cooler 18 insertion window provided in the outer case 44, and this ice making cooler 18 insertion window 44b is provided facing the entrance 45a of the attachment 45 attached to the lower surface of the ice making plate 21a. This makes it easy to incorporate the cooling device 18 (in the case of the present invention, a pipe-shaped cooling device without fins or the like). In other words, after the outer case 44 is assembled into the ice making chamber 15, the ice making cooler 18 (pipe shape) uses the elastic force of the ice making cooler 18 ahead of the ice making cooler 18 insertion window 44b, It is tightly engaged so as to slide into the mounting portion 45. The attachment portion 45 indicates a space formed between the ice making plate 21a and the attachment plate 36. Although not shown in the figure, the case 44 has a lead outlet 44c for a lead wire for supplying power to the circulation pump 24 and the like.

  Furthermore, when the ice making apparatus main body 10 is unitized, a mounting leg 46 may be provided on the case itself as shown in FIG. 8 in addition to the base plate, and each ice maker component may be incorporated in the case 44 based on the mounting leg 46. Of course. The example shown in FIG. 8 is an example in which the ice making part 21 and the cut heater 29 are assembled into a unit based on a mounting leg 46 that is integrally or separately from the outer case 44. At this time, the fixed-quantity tank 23 is not firmly fixed to the base plate or the outer case or the like, and it is necessary that the metering tank 23 be drawn out without difficulty by the user when the door is opened from the outer case.

  As described above, the unitized ice making device main body 10 is assembled in the ice making chamber 15 and the electrical wiring between the water supply tank 22, the water supply piping, and the ice making cooler are attached, for example, to the state shown in FIG. I can do it. FIG. 9 shows an example in which the case 44 is made of two parts (a container and a lid), and an example in which the ice making unit 21 and the cut heater 29 are unitized. Even in this case, the case 44 is provided with an ice making cooler insertion window 44b through which the pipe-shaped cooler 18 passes, a lead wire outlet 44c, and a water supply pipe outlet 44a. Thus, in this case, the lid of the case 44 may be opened at the time of assembling the refrigerator, and the metering tank 23 and the circulation pump 24 may be assembled in the case 44.

  As shown in FIGS. 8 and 9, the unitization of the ice making apparatus main body 10 promotes partial assembly and shortens the assembly time of the refrigerator itself. The ice making unit 21 and the cut heater 29 are housed in the case 44. This prevents dust and the like from entering the inside of the circulating water as well as the outside and prevents the user's hand from touching the ice maker components. By placing the ice making apparatus main body 10 unitized as described above in a place where the partition heat insulating wall 12 is recessed toward the freezing room side, the height of the ice making room 15 made to match the height dimension of the water storage tank 22 is set. Therefore, since it is not necessary to make it unnecessarily high, it is possible to ensure efficient storage efficiency of the refrigerator compartment. In other words, the storage place of the ice making apparatus main body 10 (ice making part) can be made inconspicuous.

  Next, the point that the ice made in the ice making chamber 15 is sent to the ice storage container 30 through the communication path will be described with reference to FIGS. FIG. 10 is a view showing the structure of the blade 51a of the damper 51 provided on the connecting road, FIG. 11 is a view showing a different example, FIG. 12 is a view showing a further different example, and FIG. 13 is used for FIG. FIG. 14 is a diagram showing the positional relationship between the damper blade and a level sensor provided in the ice storage container.

  First, a description will be given with reference to FIGS. A refrigerating chamber 2 includes a water storage tank 22 and an ice making device main body 10 (not shown). The room temperature of the refrigerator compartment 2 is set to about 0 ° C. to 5 ° C. 12 is a partition heat insulating wall (between the freezing room and the refrigeration room, between the ice storage room 3 and the ice making room 15), 12a is a connecting passage, and 30 is installed in the ice storage room 3 (room temperature -10 ° C to -20 ° C). An ice storage container 51 is a damper and a blade 51a. The damper 51 and the blade 51a shown in FIG. 4 are such that the communication path 12a is sealed with a single blade 51a, but this is divided into two blades 51a and 51a to close the communication path 12a. It is a so-called double door damper, and the two blades 51a and 51a are used to block the connecting passage 12a. The blades 51a and 51a have flexible members 51b and 51b at the tips of the blades 51a and 51a. The joints are sealed by the flexible members 51b and 51b. The blade 51a is divided into two parts in order to reduce the rotational trajectory of the damper blade and to reduce the height dimension (H dimension) of the freezer compartment in which the ice storage container 30 is placed. Further, since the height of the blades 51a and 51a is reduced, there is no need to worry about ice being involved, and there is a gap between the blades 51a and 51a because there are flexible members 51b and 51b between the blades 51a and 51a. Thus, a refrigerator with an ice making device can be obtained. Of course, the flexible members 51b and 51b use plate-like members made of silicon resin or the like that is not cured at a low temperature.

  Further, the plate-like flexible members 51b and 51b are not made so wide. This is because it is difficult to directly support ice with the plate-like flexible members 51b and 51b. Further, although not shown in the drawing on the contact surface between the communication path 12a and the blade 51a, if a sealing material is provided, the sealing performance is further improved. Here, the ice entrainment by the blade 51a will be described. When the ice block in the ice storage container 30 is in the state shown in FIG. 10, for example, the blade 51a tries to entrain the ice block when the blade 51a is rotated (closed). In the present invention, the tip of the blade 51a is flexible. Therefore, the tip of the blade 51a is deformed without lifting the ice block, thereby preventing entrainment. This prevents the blade 51a from being locked. In other words, when the flexible member 51b is not provided at the tip of the blade 51a, it is necessary to keep the ice mass away from the rotation locus of the blade 51a. That is, it is necessary to secure a distance between the upper edge 30a of the ice storage container 30 and the tip 51b of the blade 51a.

  In the structure shown in FIG. 11, blades 51a for closing the outlet holes are provided at two locations, the entrance and the exit of the communication path 12a, so that the temperature between the refrigerator compartment 2 and the ice storage room 3 is maintained. The sealing performance of 12a is also improved, and foreign matter does not accumulate in the communication path 12a (between the entrance and the exit).

  Next, in FIG. 12 and FIG. 13, a rib 51c for dropping ice from the blade is provided on the blade 51a that closes the communication path 12a, and the ice on the blade 51a falls along the slope as shown in FIG. The blade 51a is not left behind. Further, since the ice on the blade 51a is obstructed by the rib 51c and does not come into surface contact with the blade 51a, the ice tends to fall into the container by its own weight when the blade rotates. Therefore, it is possible to obtain a refrigerator with an ice making device that does not cause a sealing failure that the ice is obstructed at the next blade closing stage and the outlet cannot be sealed. Note that several ribs 51c are provided on the blade 51a as shown in FIG.

Next, in FIG. 14, this means that the ice falling from the communication path 12a is replaced with the blades 51a and. The ice storage container 30 is guided to the center of the ice storage container 30 using the rear wall surface 30a (inclined surface). At this time, the blade 51 a does not touch the rear wall surface 30 a (inclined surface) of the ice storage container 30. In this way, it is possible to prevent the ice falling from the communication path 12a to the ice storage container side from wrapping around the blade 51a without providing special parts, and the ice can be brought to the center of the ice storage container 30 so that it is convenient for the user. It becomes a refrigerator with a good ice making device. Further, by setting the full ice detection position by the level sensor 53 that controls the ice storage amount to be lower than the locus where the damper blade 51a opens and closes H1, the ice accumulated in the ice storage container 30 touches the blade 51a. Therefore, the damper blade 51a is a refrigerator with an ice making device in which the operation is not disturbed by the accumulated ice.

  15 and FIG. 16, FIG. 15 is a view showing an example in which crushing claws are arranged on an ice making plate, and FIG. 16 is a cross-sectional view taken along the line BB of FIG. Reference numeral 18 denotes an ice making cooler, 21 denotes an ice making unit, 21a denotes an ice making plate, and 28 denotes a diversion nozzle. It flows down from the diversion nozzle 28 to the ice making plate 21a and circulates. The production process of the transparent ice at this time is the same as FIG. In the figure, 52 is a drive motor for electrically crushing sheep-shaped transparent ice made on the ice making plate 21a. That is, a claw 53 is attached to the tip of the output shaft 52a of the drive motor 52 as shown in the figure. The crushing claws 53 are provided, for example, so as to protrude about 3 to 5 mm on the outer peripheral side from the output shaft 52a, and are provided on the outer periphery of the output shaft 52a at about four locations. Since ice originally does not stretch, if a slight crack is given to the ice, the ice breaks smaller than the crack. However, since it is quite difficult to specify the shape to be cracked, the mounting position of the crushing claw 53 is tended in consideration of the shape and size of the ice making plate 21a and the shape and size of the crushing claw 53.

  Further, the claw 53 is provided so as to be located at an intermediate portion in the thickness direction of the sheep-shaped transparent ice as shown in the figure. This position is not specified and may be within the thickness of the yolk-shaped transparent ice, and when the yolk-shaped transparent ice is formed in the ice making plate 21a as shown in the figure, the drive motor that receives the notification drives. To start. Of course, the output shaft torque of the drive motor 52 has such a torque that the crushing claw 53 can crush the transparent ice, and it is convenient to set it as a low-speed motor that rotates slowly about once a minute.

  In the figure, a planetary gear 54 is engaged to provide a second shaft 54a, and a claw 53 is also provided on this shaft 54a. This is to break the sheep-shaped transparent ice smaller. The crushed transparent ice is guided to the slope of the ice making plate and dropped to the ice storage container (not shown) side using an auxiliary tool (not shown). The claw 53 may crush the yolk-shaped transparent ice, and ice pieces may remain on the rising portion of the ice making plate 21a and on the bottom surface of the ice making plate 21a. Therefore, there is no problem even if some ice pieces remain. Further, the ice making plate 21a may be processed so as to be separated from the ice making plate 21a when the sheep claws 53 are crushed by the claw 53 and fall to the ice storage container side.

  Next, in FIG. 17 and FIG. 18, the relationship between the ice making plate 21 and the crushing claw 53 different from those in FIG. 15 and FIG. As shown in FIG. 17, a plurality of crushing claws 53 are attached at appropriate positions of the wire 55 that slides inside the protective tube. One end of the wire 55 is attached to a rotating body 56 attached to the output shaft 52 a of the drive motor 52, and the other end is attached to the rising wall 21 b of the ice making plate 21 via a reinforcing plate 57. The reinforcing plate 57 side is provided with a function of rewinding the wire 55. Further, as shown in FIG. 17, the wires 55 are provided in two rows with respect to the ice making plate 21 and close to the bottom surface of the ice making plate 21. When the drive motor 52 is driven and the celestial body 56 rotates as indicated by an arrow, the wire 55 slightly moves as indicated by a broken line. This movement causes the claw 53 to break the sheep-shaped transparent ice and move slightly in the ice (L2 dimension in FIG. 17b), so that the sheep-shaped transparent ice is crushed. The timing at which the drive motor 52 is driven to crush the yolk-shaped transparent ice and the handling of the crushed ice after crushing are the same as in FIGS.

  As described earlier, since ice does not stretch, the ice crushes when the crushing claw moves, causing the ice to crack and break, so if the initial torque of the drive motor is increased sufficiently, the ice making plate The ice that can be broken inside can be broken, but in order to reduce the torque, the crushing claw should have a pointed tip (no resistance) in the moving direction. Moreover, since this crushing claw is provided in circulating water, it is good to make it the shape which does not become resistance with respect to the flow direction of water as much as possible. In other words, it is the shape of the crushing claw that prevents this crushing claw and the circulating water is disturbed at the crushing claw and becomes partially cloudy ice. Therefore, the shape of the crushing claw immersed in the water needs to be a shape that does not cause water resistance at positions upstream and downstream of the flow of water.

  Next, an example in which the ice making mechanism member of the present invention is unitized to form the ice making device main body 10 will be described with reference to FIG. In the figure, 21 is an ice making unit, 21a is an ice making plate, 23 is a metering tank, 24 is a circulation pump, 25 is a water supply pipe, 27 is a water supply pipe, 28 is a diversion nozzle, 30 is an ice storage container, and 36 is a mounting plate. is there. The members (21, 21a,...) Constituting the ice making apparatus main body 10 are assembled into a base material (not shown) and unitized. Among the constituent members of the ice making apparatus main body 10, the ice making cooler 18 attached to the ice making plate 21 a is excluded from unitization.

  That is, the water supply tank 22 and the water supply pump 26 for supplying water to the metering tank 23 from the water storage tank 22 are often provided on the front side in terms of supply of tap water to the water storage tank 22 as shown in FIG. Therefore, these should be excluded from the target of unitization. In addition, the ice making cooler 18 attached to the ice making plate 21a has the same refrigeration cycle and refrigerant piping that are attached in advance to the refrigerator box, and therefore cannot be separated from the refrigeration cycle.

  Thus, 44 is an outer case for housing the members (21, 21a,...) Constituting the ice making apparatus main body 10 as a unit. The outer case 44 may be a single container or may include a few parts (for example, a lid, a container, and a member to be placed in the outer case 44). In addition, the outer case 44 has a function of blocking dust and the like from entering the circulating water from the inside and outside (outdoor). Reference numeral 44 a denotes a water supply pipe outlet provided in the outer case 44, and the water supply pipe 25 is drawn out of the outer case 44 from the water supply pipe outlet 44 a. The water supply pipe 25 drawn out from the water supply pipe outlet 44a is connected to the connection portion 25a of the water supply pipe 25 coming out from the water storage tank 22 side when the outer case 44 is assembled in the ice making chamber 15 at the lower part of the refrigerator compartment. is there.

  44b is an ice making cooler 18 insertion window provided in the outer case 44, and this ice making cooler 18 insertion window 44b is the ice making cooler 18 (in the case of the present invention, a pipe-like cooler without fins etc.). It is provided opposite to the entrance 45a of the mounting portion 45 attached to the lower surface of the plate 21a. Thus, after the outer case 44 is assembled in the ice making chamber 15, the ice making cooler 18 (pipe shape) uses the elastic force of the ice making cooler 18 beyond the insertion window 44 b of the ice making cooler 18. Then, it is tightly engaged so as to slide into the mounting portion 45. The mounting portion 45 indicates a space formed between the ice making plate 21a and the ice making portion 21. Although not shown in the figure, the case 44 has a lead outlet 44c for a lead wire for supplying power to the circulation pump 24 and the like.

  Furthermore, when the ice making apparatus main body 10 is unitized, a mounting leg 46 may be provided on the case itself as shown in the figure in addition to the base plate, and each ice maker component may be incorporated in the case 44 based on the mounting leg 46. Of course. What is shown in the figure is an example in which the ice making part 21 is assembled and unitized on the basis of a mounting leg 46 that is integrally or separately from the outer case 44. At this time, the fixed-quantity tank 23 is not firmly fixed to the base plate or the outer case, and it is necessary to have a structure that can be easily pulled out by the user when the door is opened from the outer case. As described above, by attaching the unitized ice making apparatus main body 10 to the ice making chamber 15 and installing the electrical wiring between the water supply tanks 22 and the like, the water supply piping, and the ice making cooler, for example, as shown in FIG. It becomes a state, and clear ice desired by the user can be obtained.

  Further, what is described in FIG. 19 is different from that described in FIGS. 8 and 9 because the cut heater 29 is not used to reduce the ice made by the ice making plate 21a. As described above, the claw 53 is used to break the ice. Therefore, although not shown in the drawing, a drive motor or the like for driving the crushing claw is incorporated in FIG.

  Since the present invention has the configuration as described above, the following effects can be obtained. That is, it has a refrigerator compartment, a freezer compartment, a vegetable compartment, etc. from the top, and has a dedicated cooler in the ice making unit, and water is made to flow through the ice making cooler as circulating water, and transparent ice is made in the ice making unit In the refrigerator as described above, the water storage tank for storing the water is installed in the ice making room at the lower part of the refrigeration room, and the ice making part of the ice making device main body is installed along with the water storage tank. On the ice making side, circulating water can be prevented from freezing, and on the water storage side, an ice storage container full of ice making rooms can be obtained.

  In addition, since the ice making unit is installed alongside the water storage tank that has been installed in the conventional refrigerator compartment, it is of course possible to easily arrange the piping connecting the water storage tank and the ice making unit. The user can recognize the corner at the bottom of the refrigerator compartment as an ice making corner.

  In addition, the ice making room is a room formed at the lowest stage among the compartments divided into a plurality of stages with shelf plates etc., and if the width dimension is matched to the division dimension in the width direction of the refrigerator compartment door, If one door is opened, not only the water storage tank but also the services such as a circulation pump necessary for water circulation can be easily received.

In addition, the bottom of the ice making room is composed of a partition heat insulation wall that divides the refrigerator compartment and the ice storage room, and a part of the ice making part is located in a place where the partition heat insulation wall is recessed toward the freezer compartment. As a result, the ice making unit does not protrude from the refrigerator compartment side and the refrigerator compartment is not reduced in size. Of course, the ice making unit can be arranged in a place where human eyes cannot see.

  In addition, the water storage tank and the ice making device main body are provided in the ice making room, and the water storage tank is installed so that it can be pulled out from the front side, so that the user can easily supply water to the water storage tank. is there.

  In addition, the ice making unit is installed on the back side of the water storage tank, and the ice made in the ice making unit is stored in an ice storage container provided in the ice making chamber through a connecting passage that penetrates the partition insulation wall. Of course, the ice block that has been melted does not melt in temperature, and even when the ice making unit is installed, the location covered by the water storage tank in the front is used, so the convenience of the refrigerator compartment will not drop. is there.

  Further, in a refrigerator having a refrigerator compartment, a freezer compartment, a vegetable compartment, etc. and having a dedicated cooler in the ice making unit, circulating water to the ice making cooler to make transparent ice, A connecting passage through which ice passes is formed in the partition insulation wall that divides the refrigerator compartment and the ice storage compartment up and down, and a damper blade for controlling the ice falling at the exit of the connecting passage is provided and falls into the ice storage container. A transparent portion made by the ice making unit by using a refrigerator with an ice making device provided with a flexible part that prevents the ice block from being locked by being lifted by the blade and sandwiched between the blade and the outlet. The ice can be stored for a long time in the freezer without melting it at the refrigerator temperature. In addition, since the blade is not entangled with the ice in the ice storage container when the blade rotates, the design is such that the blade rotation trajectory is within the height of the ice storage container. It can be set as the refrigerator filled with the height dimension. Therefore, it becomes an efficient refrigerator capable of reducing the distance between the blade and the ice storage container.

  Also, an ice making device in which the blade that closes the communication path through which the ice passes is divided into two, and a double-spreading system is provided, and a packing made of a flexible member is provided at the tip of both blades, and the joint is sealed with the packing By using a refrigerator with a blade, the rotation trajectory of the damper blade can be made smaller, the height of the ice storage chamber into which the ice storage container is placed can be made smaller, and it is possible to make a refrigerator with an efficient ice making device. There is no need to worry about ice being involved due to the small height dimension of the blade, and since there is a flexible member between the blades, the gap between the joints can be eliminated and the ice making device without locking etc. An attached refrigerator can be obtained.

  In addition, since the blade that closes the communication path through which ice passes is provided at two places, the entrance and exit of the hole through which ice passes, and a flexible member is provided at the tip of the blade, the sealing performance of the communication path through which ice passes is provided. As a matter of course, foreign matter is not collected and locked in the communication path through which ice passes.

  In addition, by making a refrigerator with an ice making device provided with a rib that drops ice on the slope from the blade, the ice while accumulating at the outlet is obstructed by the rib so that the blade is in perfect surface contact with the blade. Therefore, when the blade rotates, the ice is guided to the rib and falls into the container by its own weight. Therefore, it is possible to obtain a refrigerator with an ice making device that does not say that the ice is obstructed at the next blade closing stage and the outlet cannot be sealed. Furthermore, the ice is guided by the ribs, and the ice is less likely to stay on the blade.

  In addition, the rear wall surface of the ice storage container is provided with an inclined surface for guiding the ice falling through the blade to the center side of the ice storage container, and the ice stored in the ice storage container is stored in the ice storage container so as not to touch the blade. By making the refrigerator with an ice making device that secures the H1 dimension between the amount of ice and the blade lowermost end P during rotation, it is possible to prevent the ice from being caught during rotation of the blade and to place the ice in the center of the ice storage container. Since it can be brought close, it becomes a refrigerator with an ice making device which is easy to use for the user.

  In addition, by using a refrigerator with an ice making device in which the full ice detection position of the level sensor that controls the amount of ice stored in the ice storage container is set to a dimension H1 below the locus where the damper blade opens and closes, the ice stored in the ice storage container Since the damper blade is not obstructed by the ice, it becomes a refrigerator with an ice making device which does not reach a lock or the like.

  Also, in a refrigerator that has a refrigerator room, a freezer room, a vegetable room, etc. from the top and has a dedicated cooler in the ice making unit, and circulates water through the ice making unit to produce sheep-like transparent ice on the ice making plate. A claw claw that is displaced by an external force on the ice making plate and located within the thickness of the transparent ice, and during crushing, the claw claw inside the sheep-shaped transparent ice is displaced by an external force, Since the transparent ice is crushed, it is not necessary to use a heat wire that heats the inside of the refrigerator. It can also be realized. Furthermore, even if there is ice residue in the ice making plate part using this seed crushing method, the ice is once melted during the next water circulation and becomes ice again, so that the remaining ice grows in an unusually strange shape. There is no such thing as impairing the ice making function.

  In addition, the crushing claw is displaced by the drive motor, and the drive motor is installed at a position away from the ice making plate. The degree of freedom of design is expanded by not being fixed.

  Further, the crushing claw is directly attached to the shaft of the drive motor, and the crushing claw is positioned on the ice making plate, and several claw claw located on the ice making plate are displaced by the drive motor via the planetary gear to crush the ice. In this way, the crushing claw can be attached without providing any special means, and of course, the size of the crushing ice can be appropriately changed by combining the planetary gear.

  Also, a plurality of crushing claws are provided on the operating plate, and this operating plate is provided on the ice making plate and within the thickness of the transparent ice to be produced, so that the crushing claw is displaced when the transparent ice is completed. The ice can be made into a relatively stable shape.
