Description

  The present invention relates to a refrigerator that is closed in a double door manner with left and right doors in which front openings of storage rooms are arranged.

  Household refrigerators have been commercialized as refrigerators having many doors for each storage room as well as diversified cooling storage temperatures in order to meet various user needs. The top freezer type with the freezer compartment at the top, the mid freezer type with the freezer compartment between the upper refrigerator compartment and the lower vegetable compartment, the bottom freezer type with the freezer compartment at the bottom, and the upper refrigerator compartment Various forms have been commercialized, such as a type in which a vertically long freezer room and a vegetable room are arranged below, and a side-by-side type in which a freezer room and a refrigerator room are arranged side by side.

  In recent years, in consideration of convenience, the refrigerator compartment, which is frequently used and has the largest storage capacity, has been placed at the top as a double door, with an ice making room and temperature switching room below it, and a vegetable room below it. A type with a freezer compartment at the bottom is the mainstream. A partition that rotates to the other door side when the door is closed is attached to the inner surface of one open end of the double door of the refrigerator compartment. And a partition becomes an adsorption | suction surface of the gasket of a door periphery.

  Furthermore, the enlarged double doors have a longer vertical dimension, and have a problem in exterior design due to a long partition curved in the vertical direction. In order to solve the problem, the partition plate made of a thin steel plate that forms the suction surface of the door gasket of the rotating partition body is folded by overlapping the flat suction surface and both side edges thereof inward, and It is bent into a shape having an angle portion. The outer peripheral surface of the partition plate and the outer surface of the heat insulating member provided inside the partition plate are covered with a synthetic resin partition frame, and the partition plate is engaged and held by the partition frame, and a surface heater is provided on the inner surface of the partition plate. Those that have been stuck to prevent condensation on the surface of the partition plate are widely used (see, for example, Patent Document 1).

  Hereafter, the specification of the rotation partition of the conventional refrigerator is demonstrated using FIG. 18, FIG.

  The rotating partition 13 is formed of a thin steel plate partition plate 16 that is a magnetic material forming an adsorption surface, a polystyrene foamed heat insulating member 18 that forms a heat insulating layer, and forms an outer shell of the rotating partition 13 so as to cover them. A synthetic resin partition frame 17, a surface heater 19 made of an aluminum foil heater or the like disposed on the inner surface of the partition plate 16, and a guide groove on the upper end surface of the rotary partition 13. The cap member 58 is formed.

  In the above configuration, since the partition plate 16 made of a thin steel plate and the surface heater 19 are in direct contact with each other, it is necessary to provide a ground wire for connecting the partition plate 16 and the refrigerator 1 main body in order to cope with electric leakage.

  Further, the cap member 58 for fitting the refrigerator and the rotary partition 13 also serves to cover and connect the upper ends of the partition plate 16 and the partition frame 17.

JP 2010-249491 A

  However, in the above-described conventional configuration, the door gasket 12 cooled in the cold room having a low temperature is in direct contact with the partition plate 16 made of a thin steel plate having high thermal conductivity, and the partition plate 16 is moved to the inside of the warehouse. Due to the bent shape, the surface temperature of the air release portion of the partition plate 16 decreases, the capacity of the surface heater increases more than necessary, and the power consumption increases. Furthermore, since the electric wire part which connects a heater is also arrange | positioned in the partition plate 16, it had the subject that an attachment space enlarged.

  An object of the present invention is to solve the above-described problems, and to provide a refrigerator that can reduce power input to a heating means such as a heater of a rotating partition and can simplify the configuration of the rotating partition. .

In order to solve the above-described conventional problems, the refrigerator of the present invention is configured such that the left and right doors juxtaposed to the front opening of the storage chamber are closed in a double-split manner, and are vertically disposed on the inner surface of at least one of the left and right doors on the side opposite to the pivot. In a refrigerator provided with a rotating partition that extends in a direction, and the rotating partition is an adsorption surface of a door gasket, the rotating partition includes a resin partition plate that forms an adsorption surface of the door gasket, and the rotating partition A heat insulating material disposed inside, a resin partition frame covering the peripheral edge of the partition plate and the outer surface of the heat insulating material, a cap having a guide mechanism on the upper portion of the rotating partition, and facing the door gasket And a magnet provided inside the rotating partition, and a metal reinforcing plate formed in a U-shaped cross-section by bending a side surface inside the rotating partition . Side of reinforcing plate Together with the metal reinforcing plate is fixed to the resin partition frame body and formed hole and engaging members formed on the resin partition frame, the said resin partition plate resin partition frame And the metal reinforcing plate are connected and fixed by the cap.

  As a result, the temperature of the partition plate surface rises due to less thermal influence from inside and outside the cabinet, and power input to the heating means for preventing condensation is suppressed. Furthermore, the ground wire can be eliminated, and a space for arranging the magnetic body inside the partition can be secured, so that the cost can be reduced with a simple configuration.

  The refrigerator of the present invention simplifies the configuration of the rotating partition and can suppress power input for preventing condensation to be minimized, thereby saving energy.

According to the first aspect of the present invention, the left and right doors juxtaposed to the front opening of the storage chamber are closed in a double-spread manner, and a rotating partition body extending vertically on the inner surface of at least one of the left and right doors on the side opposite to the pivot is provided. In the refrigerator, wherein the rotating partition is an adsorption surface of the door gasket, the rotating partition is a resin partition plate that forms the adsorption surface of the door gasket, and heat insulation disposed inside the rotating partition. A partition wall made of resin, covering a peripheral edge of the partition plate and the outer surface of the heat insulating material, a cap having a guide mechanism at the top of the rotating partition, and the interior of the rotating partition facing the door gasket and a magnet provided in the intended rotating partition body inside the folding side portions U-shaped cross-section to form a metallic reinforcing plate is disposed, formed on the side surface of the metallic reinforcing plate Hole and said resin Together with the metal reinforcing plate in an engagement member formed in Setsuwaku body is fixed to the resin partition frame, the resin-made partition plate and the resin partition frame member and said metal reinforcing plate By connecting and fixing with the cap, warpage of the rotating partition due to a temperature difference between the inside and outside of the refrigerator can be prevented, and heat intrusion from outside to the inside of the refrigerator can be suppressed.

  Furthermore, since the partition plate surface is a single component, it is possible to provide a refrigerator having a good appearance and a high appearance quality without causing a step or a color difference.

  Further, since the partition plate is made of resin, the temperature of the partition plate surface increases, and the likelihood for the dew point temperature increases, so that it is possible to prevent dew condensation with a minimum amount of power input, thereby saving energy.

The invention according to claim 2 is the invention according to claim 1 , wherein the resin partition frame is provided with a heating means for raising a surface temperature of the resin partition plate, and the heating means is mainly used. Since the metal reinforcing plate is disposed outside the circumference, heat generated from the heating means is hardly transmitted to the inside of the warehouse, so that the amount of cooling load in the warehouse is reduced and energy is saved. On the other hand, since the heat influence from the inside of the cabinet can be reduced, variation in the temperature distribution of the partition plate surface temperature of the rotating partition is suppressed, and unnecessary power input for raising the surface temperature can be reduced, thereby saving energy. Become. Furthermore, since the amount of heat received by the metal reinforcing plate from the heating means is reduced, warpage due to a temperature difference due to thermal expansion can be suppressed.

The invention according to claim 3 is the invention according to claim 1 or 2 , wherein the distance between the flat portion formed in a U-shaped cross section of the metal reinforcing plate and the center of the heating means is as follows: By extending the distance from the end of the metal reinforcing plate to the center of the heating means, the closest distance from the center of the heating means is a plane formed in a U-shaped cross section of the metal reinforcing plate. Because it becomes a part, the insulation thickness can be maximized. Therefore, it is possible to achieve both energy securing by ensuring the strength of the rotating partition and suppressing heat intrusion into the cabinet.

According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the metal reinforcing plate is disposed in a substantially full length region in the longitudinal direction of the rotating partition, thereby preventing warping. Since the influence can be eliminated, a highly reliable door seal with reduced heat entry from the outside can be secured.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

  In FIG. 1, a refrigerator 100 has a left door 102 located on the left side and a right door 103 located on the right side, and FIG. 1 shows a state in which the left door 102 and the right door 103 are opened. . A portion where the left door 102 and the right door 103 are provided is a portion of the refrigerated storage chamber 105, and an ice making chamber 106 is provided below the left door 102, and a frozen storage chamber 107 and a vegetable compartment 108 are provided below. A switching chamber 109 is provided below the right door 103 and to the right of the ice making chamber 106.

  The left door 102 and the right door 103 are pivotally supported by hinge portions, respectively, and are configured to open to the left and right sides. A rotating partition 200 is provided on the non-pivot side of the left door 102. The rotating partition 200 rotates according to the opening / closing operation of the left door 102. When the left door 102 is closed, the non-pivot side of the left door 102 and the right door 103 is closed via the door gasket 110 to store in a refrigerator. Cold air leakage from the chamber 105 is prevented.

  Here, a heat insulating partition member (not shown) is disposed between the storage compartments, and steel cover 501, 502, 503 is disposed on the front surface of the heat insulation partition member, and each storage compartment door is provided. The door is closed via a door gasket to prevent cold air leakage from each storage room.

  Next, in FIGS. 2 to 5, the rotary partition 200 includes a partition plate 210 that forms the suction surface 111 of the door gasket 110, a polystyrene foam heat insulating material 220 disposed inside the rotary partition 200, and a partition. A synthetic resin partition frame 230 covering the peripheral edge of the plate 210 and the outer surface of the heat insulating material 220, and a heating means 240 comprising a heating portion 241 and a connection portion 242 disposed at the center of the inner surface of the partition plate 210; It is composed of In addition, a reinforcing plate 250 made of, for example, a metal plate having a small thermal expansion coefficient is disposed between the heat insulating material 220 and the partition frame 230 at substantially the entire height of the rotary partition 200 with respect to the height direction of the refrigerator.

The partition plate 210 is made of synthetic resin, and two magnetic bodies 211 are attached to the inner surface. The magnetic body 211 is configured in substantially the entire height region of the rotary partition 200 with respect to the height direction of the refrigerator, and the magnetic body configured in the door gasket 110 when the left door 102 and the right door 103 are closed. 112 is arranged so as to be opposed to 112. In this embodiment, a rectangular parallelepiped plastic magnet is used.

  The heating part 241 and the magnetic body 211 of the heating means 240 are held in pressure contact between the partition plate 210 and the heat insulating material 220. Further, the heating portion 241 of the heating means 240 is a straight line such as a linear heater, and is disposed between the magnetic bodies 211 in parallel with the magnetic bodies 211. The connecting portion 242 of the heating means 240 is an electric wire with a small resistance value that does not generate heat, and is pressed and held by the heat insulating material 220 and the partition frame 230 on the opposite side to the heating portion 241.

  Next, the overall configuration of the rotary partition 200 will be described in detail with reference to FIG. 4, and the arrangement of the heating means 240 will be described in detail with reference to FIG.

  The rotating partition 200 includes a synthetic resin partition plate 210 that forms the suction surface 111 of the door gasket 110, a styrene foam insulating material 220 disposed inside the rotating partition 200, and a metal plate reinforcing plate 250. A synthetic resin partition frame 230 covering the peripheral edge of the partition plate 210 and the outer surface of the heat insulating material 220, a heating portion 241 on the partition plate 210 side of the heat insulating material 220, and a connection portion 242 on the reinforcing plate 250 side. It is comprised by the heating means 240 arrange | positioned. A partition frame 230 and a partition plate 210 are coupled and fixed to the upper part of the rotary partition 200 in consideration of a mechanism that rotates along the guide when the door is closed by a guide 113 attached to the top surface of the refrigerator compartment. A cap 213 is attached. In the present embodiment, the cap 213 connects and fixes the partition frame body 230 and the partition plate 210, but the reinforcing plate 250 may also be connected and fixed together. In this case, the strength is further increased.

  Further, although the cap 213 is attached to the upper part of the rotary partition 200, a similar mechanism may be attached to the lower part of the rotary partition 200. In this case, since the rotary partition 200 can be fixed up and down, front and back, it is possible to eliminate the influence on the warp due to the heat effect inside and outside the cabinet and the molding of a single component.

  In addition, a heating portion 241 disposed in the center of the inner surface of the partition plate 210, and two magnetic bodies 211 are attached to the inner surface of the partition plate 210 so as to sandwich the heating portion 241. The heating means 240 is divided into a heating portion 241 (heater) and a connection portion 242 (electric wire) at the lowermost part of the assembled heat insulating material 220.

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

In the conventional configuration, the door gaskets 11 and 12 cooled by the temperature effect of the refrigerating chamber 3 are in direct contact with the partition plate 16 made of a thin steel plate having high thermal conductivity, so that the surface of the air release portion of the partition plate 16 is exposed. The temperature drops. In order to make up for this and make the dew point temperature or higher, it is necessary to increase the capacity of the surface heater 19. In the case of the present embodiment, since the partition plate 210 that forms the suction surface 111 of the door gasket 110 of the rotary partition 200 is made of synthetic resin, the relationship between the energization rate of the heating means and the surface temperature of the partition plate in FIG. As shown in the graph, the surface temperature of the partition plate 210 in this embodiment is about 3K higher than the surface temperature of the conventional partition plate 16 under the same power supply rate condition. Moreover, the energization rate for maintaining the dew point temperature when the outside air conditions are 30 ° C. and 75% can be reduced by about 10%. This is because the partition plate 210 with which the door gasket 110 contacts is made of a synthetic resin having a low thermal conductivity, so that a decrease in the temperature of the atmosphere opening portion 212 of the partition plate 210 is suppressed. Thus, the surface temperature of the partition plate 210 increasing (approaching the outside temperature) means that the thermal influence from the inside of the chamber having a low temperature is reduced. In the conventional configuration, the partition plate 16 is bent toward the inside of the cabinet to ensure the strength. Therefore, the heat of the partition plate 16 heated by the heater enters the inside of the cabinet and becomes a cooling load inside the cabinet. Since the partition plate 210 is made of a synthetic resin having a low thermal conductivity, the heat intrusion into the cabinet is suppressed and the cooling load is also reduced. Thereby, an energy saving effect can also be obtained.

  In addition, by arranging the magnetic body 211 inside the rotating partition 200 so as to face the magnetic body 112 configured in the door gasket 110, the adsorption of the rotating partition 200, that is, adsorption to the door gasket 110, is performed. Basic functions can be secured.

  Furthermore, since the surface of the partition plate 210 is composed of one part, there is no difference in level or gap between the two-part configuration that the conventional partition plate 16 is attached to, and the difference in color between parts, A refrigerator with good appearance and high quality can be provided.

  In this embodiment, a rectangular plastic magnet is used as the material of the magnetic body 211. Due to the characteristics of magnets, there are anisotropy that works strongly only in a specific direction and isotropic with almost the same magnetization intensity in any direction. In the present embodiment, an anisotropic magnet having a stronger magnetic force than isotropic is used. This is because the door gasket 110 is hardened when the temperature is low, such as in winter, and the gasket jumping property is deteriorated, and there is a concern about the gap of the gasket. Cold air leakage due to gaps can be prevented.

  The magnet becomes stronger when the width and depth are increased. In the present embodiment, the dimensions are the same as those of the magnet disposed inside the door gasket 110 and the center line is aligned. This is to prevent the magnetized surface of the magnet from having an N pole and an S pole and causing the door gasket 110 to float and create a gap due to the repulsion of the magnet. In fact, the rotary partition 200 and the door on which the rotary partition 200 is not attached may be displaced by about 2 mm when the refrigerator is used for a long time or due to variations in the door installation. For this reason, even if they deviate, it is possible to follow and prevent gasket gaps due to repulsion. If there is a possibility that the size of the displacement will increase due to the construction, such as when developing and designing a new one, the outer left and right dimensions of the magnet should be increased while matching the center line.

  In this embodiment, it is assumed that the left and right doors are displaced by about 2 mm. However, when the range of displacement is not known, the internal magnet held in pressure contact between the partition plate 210 and the heat insulating material 220. By taking play in the horizontal direction of the cross section of the partition plate 210, the magnet may move and follow the gasket even when the door is displaced. At this time, since the magnet is pressed and held by the heat insulating material 220 from behind, the magnet does not float with respect to the partition plate 210 and no gap is formed.

  Alternatively, the upper and lower ends of the magnet may be divided so that the magnet width is larger than the magnet reference width. In particular, the upper and lower ends are the four corners of the gasket, and the gasket tends to hardly follow.

  In the refrigerator of the present embodiment, the left and right magnetic forces of the magnetic body 112 adsorbed by the door gasket 110 of the left door and the right door are left <right. This is because the dimension of the door in the width direction is approximately 3: 7 on the left: right, and the door opening trajectory and the door opening force of the left door to which the rotating partition 200 is attached are large. At this time, in the refrigerator of the present embodiment, the partition plate side is also combined with the partition plate side so as not to mistakenly attach the magnets having different magnetic forces on the left and right sides in the magnet mounting operation. . The incision may be a U-shape or the end face may be C-plane cut.

In addition, since magnets have different magnetic forces depending on the magnetized surface, it is also an effective means to prevent debris in the manufacturing process. It is.

  Ferrite magnets are used as the magnet material, but the use of a strong magnet (for example, a neodymium magnet) improves the jumping property. However, since the magnet becomes expensive, it may be properly used depending on the target cost of the product.

  The attractive force of the gasket can be changed by changing the external dimensions, magnetizing method, and material of the magnet. However, it is better to use a magnet with an appropriate magnetic force in consideration of the sticking property and opening force. .

  Magnets have the property that their magnetic properties change due to thermal energy. Further, the magnet in the present embodiment uses a plastic magnet, and is made by adding a magnet material or metal powder to rubber, and thus has elastic characteristics. Therefore, in this embodiment, as shown in FIG. 3, the magnet and the heater are arranged apart from each other so as not to be directly in contact with each other so that the magnet is not directly affected by heat.

  In order to prevent direct contact between the magnet and the heater, a rib or the like may be provided between the magnet and the heater so that the magnet and the heater are not in contact with each other. In this case, since a magnet and a heater can be arranged along the rib, it also serves as a guide.

  Further, when the partition plate 210 and the partition frame 230 are made of synthetic resin, the partition frame 230 contracts due to the influence of thermal expansion, for example, when the internal temperature is low, and the partition plate 210 extends when the external temperature is high. Become. Accordingly, the rotating partition 200 is subjected to a warping force in the longitudinal direction due to the expansion / contraction difference, but since the metal reinforcing plate 250 is inserted in substantially the entire height region of the rotating partition 200, the influence of the warping can be eliminated. it can. As a result, a highly reliable door seal with reduced heat intrusion from outside can be secured.

  Next, the reinforcing plate 250 will be described.

  As shown in FIG. 2, the reinforcing plate 250 is located inside the rotary partition 200 inside the warehouse, and is disposed outside a predetermined circumference centered on the heater wire. Thereby, since it becomes difficult to transmit the heat_generation | fever of a heater to the inner side of a warehouse, the amount of cooling loads in a warehouse is reduced and it becomes energy saving. Furthermore, the back surface portion of the reinforcing plate 250, that is, the shape inside the warehouse is a shape arranged substantially in parallel with the partition frame 230, and the side surface portion of the reinforcing plate 250 is a bent shape. That is, it is formed in a U-shaped cross section. Further, a method is adopted in which a hole is formed in the side surface portion and fixed to a claw taken out from the partition frame body 230. Thereby, the influence by the thermal expansion by the temperature difference in the inside and outside of a store | warehouse | chamber is suppressed, and the curvature of a longitudinal direction is suppressed.

  In the present embodiment, the reinforcement plate 250 is fixed to the partition frame body 230 with a claw. However, the reinforcement plate 250 is provided with a through-hole in the back surface portion, and the partition frame body 230 is provided with a hooking mechanism. 250 can be fixed to the partition frame 230 while sliding. In this case, by setting the number of through holes appropriately, it is possible to reduce work man-hours and maintain the maximum fixing strength. In the case of the slide mechanism, since it can be visually understood that the reinforcing plate 250 is fixed to the partition frame 230, the accuracy of work and the reliability can be improved.

In the present embodiment, the reinforcing plate 250 and the rotary partition 200 have a thermal edge cutting structure. This is because the rotating partition 200 is cooled by the refrigeration temperature zone of about 0 to 10 ° C. in the warehouse, and the cold heat is transferred from the rotating partition 200 to the reinforcing plate 250. As a method of suppressing this heat transfer, a thermal edge cutting structure is provided. When the reinforcing plate 250 and the partition frame 230 come into surface contact, heat transfer is facilitated, and the warp strength of the rotary partition 200 itself is also deteriorated. The specific thermal edge cutting structure is the partition frame 230.
Ribs are provided to create a gap with the reinforcing plate 250. The height of the rib is not more than half the plate thickness of the partition frame 230, and is about 1 mm. Further, this rib also serves as a guide when the reinforcing plate 250 is attached to improve workability. Furthermore, the partition frame 230 itself has an effect of suppressing warpage and torsion, and an optimal position and shape may be selected using analysis or the like.

  In the present embodiment, the rib shape is used, but a point contact may be used as the protrusion. In this case, heat transfer is further suppressed.

  The partition frame body 230 itself can also be made into a thermal edge cutting structure by partially thinning. Moreover, you may make a through-hole rather than thin wall and give a heat insulating material to a hole part. Thereby, it becomes difficult to transfer heat further.

  By providing a hole in the back plane portion of the reinforcing plate 250 where the strength is hardly affected, the weight of the component itself can be reduced, and the cost and weight can be reduced by reducing the material cost. In the present embodiment, a plurality of approximately 35 × 15 mm long holes are provided in the flat portion of the reinforcing plate 250. By drilling holes where the effect of deformation and displacement is small while conducting strength analysis and prototype testing, it is possible to reduce the weight by about 15% while ensuring strength.

  The reinforcing plate 250 has a U-shaped cross-section with both ends bent, and the bending dimension height (flange height) is larger than the plate thickness. That is, the reinforcing plate 250 itself has a shape that ensures strength. Specifically, the plate thickness is t1.0 mm, the flange height is 13.0 mm and 8.5 mm, and the height is different on the left and right. This is because the left and right thicknesses are different on the rotation trajectory of the rotary partition 200 when the door is opened and closed.

  The thickness of the reinforcing plate 250 and the height of the flange are factors that affect the strength of a single unit. In general, the strength (second moment of cross section) is expressed by a bending stress of (the cube of width) × height / 12. It can be expressed as By increasing the height of the flange, which is the height, the strength of the reinforcing plate 250, that is, the strength of the rotary partition 200 can be increased. However, if the height of the flange is increased, the heater is likely to be affected by the heat generated and becomes heat entering the cabinet, which may increase power consumption. Therefore, in the present embodiment, on the outside of a predetermined circumference centered on the heater wire, the relationship between the distance from the heater wire center to the back flat portion of the reinforcing plate 250: X and the distance to the flange: Y is as follows. , X ≦ Y is intended to save energy by suppressing strength and heat penetration into the interior.

  The length of the rotary partition 200 according to the present embodiment is about 800 mm, but the longitudinal direction of the rotary partition 200 is due to the future increase in the capacity of the refrigerator or the size of the refrigerator compartment. In order to ensure the strength of the reinforcing plate 250, it is preferable to decrease the plate thickness while increasing the flange height, or increase the plate thickness to decrease the flange height.

  The reinforcing plate 250 of the present embodiment suppresses corrosion by applying a galvanizing process to the surface. The reinforcing plate 250 is disposed inside the rotary partition 200 and is not directly corroded without being exposed to the outside air. However, when the surface is subjected to galvanizing treatment, the reinforcing plate 250 is exposed to rainwater for a long period exceeding 10 years. However, it does not impair the function.

The reinforcing plate 250 according to the present embodiment is disposed substantially at the entire height of the rotary partition 200, and the top surface side of the refrigerated storage chamber in the longitudinal direction is bent and fixed to the cap 213 with screws. As a result, it is possible to suppress deformation by increasing the strength against warping and increasing the fitting force between the cap 213 and the rotary partition 200 that are stressed when the door is opened and closed. Since the cap 213, the reinforcing plate 250, and the partition frame 230 are fastened together with screws, the cost is reduced by reducing the number of work steps and the number of parts.

  In the present embodiment, the upper part of the rotary partition 200 has been described, but the reinforcing plate 250 and the partition frame 230 may be fastened together with screws at the lower part. By fastening the cap 213, the reinforcing plate 250, the partition frame 230, and the partition plate 210 together with screws at the upper and lower portions, a stronger fitting can be achieved.

  The reinforcing plate 250 is disposed in substantially the entire height region of the rotary partition 200, but at least a part of the back plane portion of the reinforcing plate 250 includes upper and lower parts including a fixed connection portion between the rotary partition 200 and the refrigerator compartment door. The strength of the rotary partition 200 is ensured by disposing it to the end.

  Next, the heater for heating in this embodiment will be described.

  In FIG. 7, the heating means 240 includes a heating portion 241 of a linear heater having a length L on the right side of the alternate long and short dash line and a connecting portion 242 such as an electric wire that does not generate heat on the left side of the alternate long and short dash line. As shown in FIG. 4, the heating portion 241 has a length substantially the same as the entire height of the rotary partition 200 and is disposed at the center of the synthetic resin partition plate 210. The heating portion 241 has a variable calorific value, that is, a watt density. In FIG. 7, the sections a, b, and c are variable. As specific means for changing the heater of the heating portion 241, the resistance value can be changed by changing the winding pitch of the linear winding resistance wire, or the resistance paste component of the printing resistor can be changed to make the sheet resistance. This is possible by connecting in series the heating resistance wires having different resistance values. In this embodiment, the region is divided into three sections, but may be divided into a plurality of sections according to the purpose.

  In FIG. 8, when the heater is not energized, the surface temperature of the partition plate 210 is high at the center (part b) as shown by the dotted line, and the temperature decreases toward both ends (parts a and c). This is because non-uniform temperature distribution occurs due to the sealing property and heat conduction between the refrigerated storage chamber 105 and the door gasket 110, or the influence of cold air circulation in the refrigerated storage chamber 105. In order to open and close the door, the upper and lower ends of the rotary partition 200 are provided with a gap with the inner box. The gap between the left and right gaskets is used to prevent leakage of cold air inside and outside the cabinet. However, since the cold air circulating inside the cabinet easily enters the gap, the surface temperature tends to be low. Next, when the heater is energized, since the surface temperature of the partition plate 210 is in the dew condensation region, it is necessary to energize the heater to raise the temperature of each part to a temperature above the dew condensation boundary line.

  At this time, in a heater with a constant calorific value indicated by a one-dot chain line as in the prior art, since the temperature rise of each part is constant, it is necessary to match the calorific value to the parts a and c having the lowest temperature. Unnecessary temperature rise occurs as shown by the alternate long and short dash line.

  On the other hand, in this embodiment, as shown in FIG. 7, the amount of heat generated by the heater is variable depending on the part. That is, as shown by the solid line, the part b reduces the amount of heat generation and increases the part a and c. By doing so, the surface temperature (dotted line) of the partition plate 210 without energizing the heater can be made a uniform surface temperature (solid line) exceeding the dew point boundary line as much as possible. Compared with the conventional heat generation amount of the heater, the heat generation amount for the area surrounded by the oblique lines is unnecessary, and the power consumption can be reduced accordingly.

  As described above, in the present embodiment, the heating portion 241 of the heating means 240 is divided into a plurality of parts, and the watt density of each part is variable, so that the shape of the rotary partition 200 of the refrigerator 100 is changed. The surface temperature of the partition plate 210 is made uniform even when there is a difference in heat insulation performance due to changes or the like, so there is no variation in temperature distribution and unnecessary power input can be reduced.

The heating means 240 has a switching portion 243 that electrically connects the heating portion 241 of the heater and the connecting portion 242 of the electric wire within the range of the portion a. The switching portion 243 is required to be waterproof, and is generally sealed with a resin mold or tube, and becomes thicker than the linear shape of the heating portion 241.

  In the present embodiment, an aluminum foil heater in which a heater is welded to an aluminum foil is used. Thus, the heater can come into surface contact with the surface of the partition plate 210 via the aluminum. In addition, you may arrange | position a heater without aluminum. In this case, since it can fix easily by attaching a groove | channel etc. to the partition plate 210 and pressing and inserting a heater, material cost reduction and simplification of a process are attained.

  In the part of the partition plate 210 that contacts the heater, if the plate thickness is reduced, heat transfer is improved, and the heater capacity can be reduced, thereby saving energy. If the thickness is reduced, it may increase the cost due to poor appearance due to the occurrence of sink marks on the surface and high molding accuracy, resulting in a decrease in productivity. In this embodiment, the thickness of the portion of the partition plate 210 in contact with the heater is increased. Is 1 mm or more. This balances energy savings with cost.

  The part of the partition plate 210 in contact with the heater may have a multi-layer structure of about three layers by stacking thin plates or films. In this case, even if a thickness of 1 mm or less cannot be achieved by the molding machine, heat transfer can be improved by stacking, for example, thin flat plates only on the portion where the heater contacts.

  The inside of the rotary partition 200 is provided with a heat insulating material 220 made of styrene foam as a heat insulating material, and the foaming density is about 30%. By this low density foaming, the strength of the heat insulating material itself is secured, and the warp strength of the rotating partition 200 itself is also improved. Furthermore, it is good also as a low foaming density.

  In the present embodiment, the heat insulating material 220 made of polystyrene foam is disposed, but urethane foam having high heat insulating performance may be used. In this case, since the thermal conductivity representing the heat insulation performance is improved by about three times, further necessary heater capacity can be reduced and energy saving can be promoted. In addition, since the urethane is poured into the inside and foamed rather than the molded foamed polystyrene, the strength of the rotating partition as a whole can be increased by close contact with surrounding parts.

  Further, a vacuum heat insulating material may be disposed inside the rotary partition 200. In this case, since the heat insulation performance is further improved, it is possible to further suppress the thermal influence from the inside of the warehouse, and the vacuum heat insulating material serves as a pillar, so that the strength is increased.

  A vacuum heat insulating material may be disposed inside the heat insulating material 220 made of foamed polystyrene and integrally foamed. In this case, since the periphery of the vacuum heat insulating material is covered with the heat insulating material 220, heat wraparound by the outer skin of the vacuum heat insulating material does not occur, and the structure has excellent heat insulating performance, and the required heater capacity and energization rate can be reduced. Therefore, it becomes energy saving.

  The partition plate 210 is made of synthetic resin. In this embodiment, PS (polystyrene) is used. ABS material may be used. In this case, a plasticizer (an additive that softens the resin) is mixed in the heater wire, the welded portion that connects the heater wire and the wire portion, a magnet, or the like. It becomes more difficult to migrate.

  Since the ABS material is more expensive than the PS material, the migration can be eliminated by attaching or covering the aluminum tape as a consideration for the migration of the plasticizer.

As the material of the partition plate 210, a material containing a magnetic material or a material having a magnetic coating applied to the surface may be used. In this case, since the adhesion to the gasket and the jumping property are improved, the magnetic body 211 may not be used if it is strong. Thereby, since the thickness of a heat insulating material can be increased, the cost reduction of a direct material and a man-hour can be aimed at by the further energy saving and reduction of a number of parts.

  As described above, in the present embodiment, the rotary partition 200 that extends in the vertical direction is provided on the inner surface of at least one of the left and right doors of the refrigerated storage chamber 105 (here, the left door 102) on the side opposite to the pivot. Then, the adsorption surface 111 of the door gasket 110 is used as a resinous partition plate 210, and a magnetic body 211 is disposed inside the partition plate 210 at a position facing the magnetic body 112 built in the door gasket 110, and is added between the magnetic bodies 211. The heating portions 241 of the heating means 240 are arranged linearly in parallel, and the peripheral edge of the partition plate 210 and the outer surface of the heat insulating material 220 are covered with a resin partition frame 230, and the rotating partition 200 is made of metal. Since the reinforcing plate 250 is disposed and the metallic reinforcing plate 250 has a U-shaped cross section and is locked to the partition frame 230, it is possible to prevent the rotating partition 200 from warping due to a temperature difference between inside and outside the cabinet. of It is possible to suppress heat penetration into the inner.

  Furthermore, the surface temperature of the partition plate 210 can be maintained higher than that of a conventional thin steel plate, and the power input of the heating means 240 for preventing condensation is reduced, so that the power consumption of the refrigerator 100 can be reduced.

  Further, since the connecting portion 242 of the heating means 240 is disposed on the opposite side of the heating portion 241 via the heat insulating material 220, the heating portion 241 is disposed linearly and is disposed on the inner surface of the partition plate 210. Since the mounting space 211 can be secured and the magnetic body 112 on the inner surface of the door gasket 110 is accurately opposed, the reliability of the suction state between the rotating partition 200 and the door gasket 110 can be secured.

  Further, the heating means 240 is disposed on the inner surface of the partition plate 210 made of synthetic resin, and the portion touched by a person is a synthetic resin, so there is no need to cope with electric leakage, and the cost can be reduced by eliminating the ground wire. .

  Further, since the metal reinforcement plate 250 is inserted between the heat insulating material 220 and the partition frame body 230 at almost the entire height region, the rotation partition body 200 of the rotating partition body 200 due to the difference in thermal expansion between the partition plate 210 made of synthetic resin and the partition frame body 230. Warpage can be prevented, and a highly reliable door seal with reduced heat entry from the outside can be secured.

9 is a cross-sectional view showing a main part of the refrigerator compartment in the closed state according to the second embodiment of the present invention, FIG. 10 is a cross-sectional view taken along the line DD of FIG. 9 according to the second embodiment, and FIG. 2 is an exploded perspective view of the rotating partition of the refrigerator compartment according to FIG. 2, and FIG. 12 is a specific configuration diagram of the heating means of the refrigerator according to the second embodiment. In addition, about the same structure as Embodiment 1, the same code | symbol is attached | subjected and a different part is demonstrated.

  9 to 12, the heating portion 241 of the heating means 240 is disposed between two magnetic bodies 211 that are linearly disposed on the partition plate 210, and two (reciprocating) heating portions 241. Are held in pressure contact with the heat insulating material 220 so as not to contact the magnetic body 211 in parallel. In this embodiment, two heating portions 241 are arranged between the magnetic bodies 211, but the number may be increased as long as a space can be secured.

  Further, the heating means 240 has a switching portion 243 that electrically connects the heating portion 241 of the heater and the connection portion 242 of the electric wire within the range of the portion a. The switching portion 243 is required to be waterproof, and is generally sealed with a resin mold or tube, and becomes thicker than the linear shape of the heating portion 241. Therefore, the number of warming portions 241 that run side by side is smaller than that of the other parts b and c.

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

  As described in the first embodiment, the watt density of the heater of the heating portion 241 is similarly varied so that the surface temperature of the partition plate 210 shown in FIG. In the present embodiment, since a plurality of heating portions 241 are arranged, a desired temperature increase can be obtained with a lower input than in the first embodiment.

  However, there are switching portions 243a and 243b in the portion a, and the number of the heated portions 241 is smaller than that in the portion c, and the heater having the same watt density as the portion c is insufficiently heated. Therefore, since the heater wire of the part a has two parts c, if the watt density of the part a is about twice that of the part c, an equivalent temperature rise can be obtained.

  In the present embodiment, the watt density is increased with respect to the part a. However, it may be performed for an arbitrary part where the number of heaters of the heating portion 241 is smaller than the other parts.

  As described above, in the present embodiment, since the plurality of heating portions 241 of the heating means 240 are linearly arranged between the magnetic bodies 211 inside the partition plate 210, arrangement in a narrow space is possible. In addition, the watt density per unit length of the heater of the heating portion 241 can be reduced or the energization rate can be lowered, and the input power for preventing condensation can be reduced. Furthermore, since the heating means 240 is constituted by only one side surface of the heat insulating material 220, wiring work can be simplified and man-hours can be reduced.

  Moreover, the watt density of each part is made variable as the part which divided | segmented the heating part 241 of the heating means 240 into several, and the watt density of the range of the heating part 241 parallel to switching part 243a, 243b is set to another range. By making the watt density larger than the watt density, the surface temperature of the partition plate 210 of the rotating partition 200 is made uniform by compensating for the shortage of temperature rise due to the decrease in the number of the heating portions 241 near the switching portions 243a and 243b. The variation is eliminated and the power input can be further reduced.

(Embodiment 3)
FIG. 13 is an exploded perspective view of the rotating partition of the refrigerator compartment according to the third embodiment of the present invention, and FIG. 14 is a specific configuration diagram of the heating means of the refrigerator according to the third embodiment. The same components as those in the first and second embodiments are denoted by the same reference numerals, and different portions will be described.

  13 and 14, switching portions 243 a and 243 b that electrically connect the connecting portion (electric wire) 242 and the heating portion (heater) 241 of the heating means 240 are close to the center in the longitudinal direction of the rotary partition 200. Arranged. A part d having a watt density W1 and a length L1 is connected to the connection part 242 side of one switching part 243a, and a part j having the same watt density W1 and a length L1 is connected to the other switching part 243b. Further, a part e having a watt density W2 and a length L2 and a part f having a watt density W3 and a length L3 are sequentially connected to the part d. In addition, a part i having a watt density W2 and a length L2 and a part h having a watt density W3 and a length L3 are sequentially connected to the part j, and finally a part g having a watt density W4 and a length L4 is connected to the part j. A closed loop heater having a variable watt density connected to f and part h is formed. In the present embodiment, the heat generating parts are seven places from parts d to j, but the number of parts may be any number where the watt density and the length are symmetric with respect to the switching parts 243a and 243b.

  Moreover, since the site | part g of the heating part 241 which runs alongside the switching site | part 243a, 243b has few numbers than another site | part, what is necessary is just to enlarge a watt density. That is, it is general that the relationship is W4> (W1 to W3).

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

  When the heating means 240 is energized, j generates heat from each portion d of the heating portion 241, and the surface of the partition plate 210 is stabilized at a desired temperature over the entire length L. At this time, some work mistake occurs and the switching parts 243a and 243b are reversely installed, that is, the order of the correct heat generation part of the heating part 241 is d → e → f → g → h → i → j, but j → i → In the order of h → g → f → e → d, if the watt density and length of each part d to j are different, the surface temperature of the partition plate 210 will vary greatly if installed in reverse. The temperature distribution becomes uneven.

  However, in the present embodiment, even if the switching portions 243a and 243b are reversely installed, the relationship between the watt density and the length in the entire length L of the warming portion 241 is vertically symmetrical, so that it is not different from regular mounting.

  As described above, in the present embodiment, the watt density and the length of the portion d of the heating portion connected to one switching portion 243a are equal to the portion j of the heating portion connected to the other switching portion 243b. In addition, the watt density is variable, and the parts e and i of the heating part connected in order to each other are similarly made to have the same watt density and length, that is, a symmetrical heat generation distribution centering around the switching parts 243a and b. In the heating means 240, the switching parts 243a and 243b are arranged at the center in the longitudinal direction of the rotary partition 200. Therefore, when the heating means 240 is mounted in the assembly work of the rotary partition 200, the switching parts 243a and 243b are arranged. Even when fixed in reverse, the relationship between the watt density and the length of the heating portion 241 that is variable is vertically symmetric, and the surface of the partition plate 210 of the rotating partition 200 is the same. Temperature is also the same. Therefore, not only assembly failures in the work process can be eliminated, but also the number of man-hours to be mounted after confirming the orientation of the heating means 240 can be significantly reduced.

FIG. 15: is sectional drawing which shows the principal part in the closed state of the refrigerator compartment by Embodiment 4 of this invention. The same components as those in the first to third embodiments are denoted by the same reference numerals, and different portions will be described.

  In FIG. 15, as in the first to third embodiments, a styrofoam heat insulating material 220 and a heating means 240 and a reinforcing plate 250 made of a metallic plate are arranged on the back side in the rotary partition 200. Yes, the reinforcing plate 250 is disposed in substantially the entire height of the rotary partition 200 with respect to the height direction of the refrigerator. The partition plate 210 is made of synthetic resin, and a metal plate 260 is disposed on the front surface.

  In the present embodiment, since the metal plate 260 is arranged from above the partition plate 210 so as to fit the suction surface 111 of the door gasket 110, a magnet for suction becomes unnecessary, and the heat insulating material inside the rotary partition 200 is provided. Therefore, it is possible to reduce the influence of cooling from the interior and reduce the required heater capacity and energization rate, so that energy can be saved.

  Furthermore, unlike the reinforcing plate 250 for securing the strength of the rotating partition 200, the metal plate 260 is used for adsorbing the door gasket 110, and thus can be thin. Further, since the end face does not need to be folded back, the weight can be reduced, the shape can be simplified, and the cost can be reduced.

  If the metal plate 260 is used for ensuring strength, the thickness UP and the end face folding are performed, so that the reinforcing plate 250 and the stronger rotating partition 200 can be configured.

FIG. 16: is sectional drawing which shows the principal part in the closed state of the refrigerator compartment by Embodiment 5 of this invention. The same components as those in the first to fourth embodiments are denoted by the same reference numerals, and different portions will be described.

  In FIG. 16, as in the first to third embodiments, a polystyrene foam heat insulating material 220 is disposed inside the rotary partition 200, and a metallic plate reinforcing plate 250 is disposed on the back side. . The partition plate 210 is made of synthetic resin, and a heating means 240 and a metal plate 260 are disposed on the front surface of the partition plate 210.

  In the present embodiment, the heating means 240 and the metal plate 260 are arranged from above the partition plate 210 so as to match the adsorption surface 111 of the door gasket 110. This eliminates the need for a magnet for adsorption and allows a large amount of heat insulating material inside the rotary partition 200, thereby reducing the effect of cooling from the interior and reducing the required heater capacity and energization rate, thereby saving energy. I can do it.

  Furthermore, since the heating means 240 is disposed outside the outer frame, which is the outer dimension of the rotary partition 200, the thermal effect from the cold room 3 that is at a low temperature is less affected by edge cutting. Yes. On the other hand, it is difficult for the heat of the heating means to be transferred to the inside. In addition, since the heated heat can be directly transmitted to the metal plate 260, the heater capacity and power supply rate may be small, and energy saving is excellent.

  Furthermore, by attaching the heating means 240 and the metal plate 260 after assembly, workability can be improved and man-hours can be reduced by shortening the work time.

  In FIG. 17, the rotary partition 200 includes a partition plate 210 that forms the suction surface 111 of the door gasket 110, a polystyrene foam insulating material 220 disposed inside the rotary partition 200, a peripheral portion of the partition plate 210, and It is composed of a synthetic resin partition frame 230 that covers the outer surface of the heat insulating material 220, and a heating means 240 that includes a heating portion 241 and a connection portion 242 disposed in the center of the inner surface of the partition plate 210.

  In the present embodiment, a reinforcing plate 250 is disposed between the heat insulating material 220 and the partition plate 210 in substantially the entire height region of the rotary partition 200 with respect to the height direction of the refrigerator. Heating means 240 is disposed between 250.

  The surface in contact with the inside of the partition plate 210 of the reinforcing plate 250 is disposed so as to face the magnetic body 112 configured in the door gasket 110, and in particular, forms the width direction with the center line. This eliminates the need for a magnet for adsorption, ensures the strength of the rotating partition 200 and the adhesion to the door gasket 110, and also reduces the material cost and mold cost due to the simplification of the configuration and the number of man-hours in the manufacturing process. Can be reduced.

  In the present embodiment, the heater arrangement of the heating means 240 is described as one, but a plurality of heaters may be provided.

  The portion of the reinforcing plate 250 that is combined with the magnetic body 112 configured in the door gasket 110 is in contact with the inside of the partition plate 210 to improve the appearance quality, but is exposed to the surface and directly exposed to the door gasket 110. You may make it contact. By doing so, the jumping property is improved and the adhesion is improved.

  As described above, the refrigerator according to the present invention is such that the partition plate which is the adsorption surface of the rotating partition and the door gasket is made of resin, and power consumption can be reduced while preventing condensation, so that a commercial refrigerator or the like It can also be applied to. Moreover, the method of arranging a magnetic body on the inner surface of the resin flange and adsorbing it with the door gasket can also be applied to the front cover of the heat insulating partition member that partitions the storage compartments of the refrigerator.
