Description

refrigerator

The invention relates to a refrigerator with a double-opening door.

In recent years, in order to achieve optimal operation according to the environment in which the refrigerator is installed, refrigerators equipped with temperature sensors and humidity sensors have increased. For example, there is a refrigerator in which the refrigerator compartment door is divided into left and right, and a partition between the refrigerator compartment door is provided with a heater to prevent condensation. By matching the surrounding room temperature and humidity, it changes according to the time ratio. The heater is energized and the surface temperature of the partition is adjusted to improve energy efficiency.

In addition, the partition is generally installed on one of the left and right refrigerating compartment doors, and is fixed to the door with a hinge at the upper or lower part of the partition, and adopts the protrusion of the guide member provided on the upper part of the refrigerating compartment to open and close. The structure of the refrigerating compartment door when rotating.

In addition, in order to prevent the partition from contacting with the opening of the refrigerating compartment and rotating smoothly, the partition is installed in the following manner so that the length of the partition in the long side direction is shorter than the height of the opening of the refrigerating compartment, and vertically A gap of the degree between the partition and the opening of the refrigerating compartment is formed. Furthermore, in order to close the upper and lower gaps, spacer fins are provided on the upper and lower parts of the spacers of the left and right refrigerating compartment doors. When the left and right refrigerating compartment doors are closed, the left and right spacer fins overlap and block Live the gap.

There is no heat insulation material in the gap blocked by the shim fin, and the temperature of the shim fin is difficult to rise when the heater is energized, so the condensation resistance of the shim fin is low. As one of the methods for improving the dew condensation resistance of the spacer fin, there is a technique of adjusting the heat generation amount according to the position of the partition plate (for example, refer to Patent Document 1).

In Patent Document 1, the heating value is adjusted by changing the winding pitch width of the heating wire in the longitudinal direction by the linear heater constituting the heating body provided on the separator. Furthermore, in order to increase the amount of heat generated above and below the separator, by narrowing the width of the winding pitch of the heating wire, the temperature of the gasket fin can be easily increased, and the condensation resistance of the gasket fin can be improved. [Prior Patent Document] [Patent Literature]

[Patent Document 1] JP 2016-44887 A

As shown in Patent Document 1, in order to change the width of the winding pitch of the heating wire in the longitudinal direction, for example, a device that can change the speed of feeding the glass fiber core material is required. In addition, the production time per unit length is longer than that of the equal pitch. time consuming. Therefore, there are problems of high manufacturing costs and poor manufacturing efficiency.

[Effects of Invention]

According to the refrigerator of the present invention, the pattern width of the cord heaters at the upper and lower parts of the partition is greater than the distance between the outer sides of the left and right magnets. Therefore, the temperature of the upper and lower parts of the magnet is likely to rise, and the temperature of the shim fins provided on the upper and lower parts of the shim can also rise. As a result, the condensation resistance of the gasket fin can be improved. In addition, the cord heater is constructed by winding the heating wire around the core material at equal intervals, and since the winding pitch width of the heating wire is not changed in the longitudinal direction, the manufacturing cost and the manufacturing efficiency can be improved.

As shown in FIG. 3, the compressor 12, the machine room condenser 13, and the dryer 19 are installed in the machine room 34, and this machine room 34 is installed in the lower part of the back side of the refrigerator 100. In addition, the top surface condensation pipe 15 extends from the left side surface condensation pipe 14 of the left side surface to the top surface and is connected. In addition, the top surface condensation pipe 15 may extend from the right side surface condensation pipe 17 of the right side surface to the top surface and be connected. Also, the left side condensation pipe 14, the top surface condensation pipe 15, the back condensation pipe 16, and the right side condensation pipe 17 are not shown, but are fixed to the inner surface of the metal outer box of the refrigerator 100 with aluminum tape.

In addition, the refrigerator 100 includes: a machine room cooling fan (not shown), which is installed in the machine room 34 and cools the machine room condenser 13 and the compressor 12; and a cooling fan (not shown) in the refrigerator.

In addition, if it is the downstream side of the dew condensation prevention pipe 18 after passing through the piping of the condensation system, two capillaries 20 or a plurality of coolers 21 may be installed. In addition, when two capillary tubes 20 are installed, a three-way valve is installed on the upstream side of the capillary tubes 20. In addition, if the condensation performance can be obtained only by the left side condensation pipe 14 and the right side condensation pipe 17, the machine room condensation device 13, the top surface condensation pipe 15, and the back condensation pipe 16 are not provided and there is no problem.

As shown in FIG. 3, the dew condensation prevention pipe 18 is arrange|positioned in the front flange part 70 so that the refrigerator compartment 1, the ice compartment 2, the small freezer compartment 3, the freezer compartment 4, and the vegetable compartment 5, ie, each storage compartment, are arrange|positioned.

Here, the case where the heat insulation performance between the wall surface of the refrigerating compartment 1 and the outer box is good is, for example, the distance between the wall surface of the refrigerating compartment 1 and the outer box, that is, the case where the insulation thickness is thick, or the case in the refrigerating compartment 1 The vacuum insulation material is placed between the wall surface and the outer box.

In the structure shown in FIG. 4, since the condensation preventing pipes 18 are not arranged on the upper side and the left and right front flanges 70 of the refrigerator compartment 1, the temperature of the front flange 70 around the periphery of the partition plate 8 is higher than that of the arrangement The condition of the dew condensation prevention pipe 18 is reduced. However, if the temperature rises above due to the pattern arrangement of the heaters in the partition plate 8 described later, the temperature of the spacer fins 63 and 65 of the gap between the upper surface of the refrigerator compartment 1 and the partition plate 8 is prevented from falling. Moreover, by reducing the length of the dew condensation prevention pipe 18 to be arranged, the material cost and the manufacturing cost required for the arrangement of the condensation prevention pipe 18 can be reduced.

Fig. 5 is a longitudinal sectional view of the upper part of the refrigerator 100 of this embodiment. In addition, the arrow in Figure 5 indicates the direction of wind, and the size of the arrow indicates the amount of wind. As shown in FIG. 5, on the back side of the refrigerator 100, a control device 29 is provided. The control device 29 is composed of, for example, dedicated hardware or a CPU (Central Processing Unit, also known as a central processing device, processing device, arithmetic device, microprocessor, and processor) that executes programs stored in memory.

In the refrigerating compartment 1, a refrigerating compartment temperature sensor 32 for detecting the temperature of the refrigerating compartment 1 (hereinafter referred to as the refrigerating compartment temperature) is provided. As long as the refrigerating compartment temperature sensor 32 can detect the temperature of the refrigerating compartment, the setting position in the refrigerating compartment 1 is irrelevant. The control device 29 opens and closes the baffle 85 of the baffle device 31 for the refrigerating chamber according to the temperature of the refrigerating chamber detected by the refrigerating chamber temperature sensor 32, thereby performing air blowing or blocking of the cold air in the refrigerating chamber 1. Here, the baffle device 31 for refrigerating compartments is provided in the refrigerating compartment blowing air passage 24, and the refrigerating compartment blowing air passage 24 is formed on the back side of the refrigerator 100. As shown in FIG. In addition, the refrigerator compartment temperature sensor 32 is used for energization control of a heater (not shown) and the aluminum foil heater 43 described later, and the heater is installed in the refrigerator compartment for temperature compensation. In 1, the aluminum foil heater 43 is installed in the separator 8.

Inside the refrigerator inside the refrigerator compartment left door 6 and the refrigerator compartment right door 7, three bags 26 are installed along the height direction, and the refrigerator compartment 1 is divided into a plurality of parts by a plurality of shelves 30.

Below the shelf 30 at the bottom of the refrigerator compartment 1, there is a quench chamber 27 (about 0°C) lower than the temperature (about 3°C) of the refrigerator chamber 1, and a quench chamber 27 for storing food is provided in the quench chamber 27. Box 28. In addition, each part of the wall on the deep side of the refrigerating compartment 1 divided by a plurality of shelves 30 is formed with air outlets 37 to 41 through which air is blown from the air passage 24 of the refrigerating compartment.

Fig. 6 is an exploded view of the partition 8 of the refrigerator 100 of this embodiment. As shown in FIG. 6, an aluminum foil heater 43 is attached to the back side of the surface plate 42 that is the surface side of the partition wall 8, and the aluminum foil heater 43 is formed in a serpentine pattern along the longitudinal direction. Furthermore, on the back side of the aluminum foil heater 43, the surface frame type resin member 44 is attached by fitting its claws (not shown) with the claw receiving portion 57 of the surface plate 42. In addition, an upper hinge member 49 is attached to the upper side of the back side resin member 53 to be the back side of the partition plate 8, and the upper side cover member 48 is fixed therefrom with screws 46. In addition, a lower hinge member 51 is attached to the lower side of the back side resin member 53, and the lower cover member 50 is fixed by screws 46 from below. In addition, a spring stopper 47 is fixed to the lower hinge member 51 with a screw 46, and a spring 52 is attached to the spring stopper 47. In addition, the back side resin member 53 in this state is fitted with the back side of the front frame type resin member 44 via the claw 68 of the front sheet metal 42 via the heat insulating material 45.

Fig. 7 is a schematic view showing a cross section around the aluminum foil heater 43 and the detail of the cord heater 56 constituting the partition plate 8 of the refrigerator 100 of the present embodiment. As shown in FIG. 7, the aluminum foil heater 43 is composed of a cord heater 56, an aluminum foil 54 for fixing the cord heater 56, and a double-sided tape 55, and the double-sided tape 55 is pasted on the back of the surface plate 42 side. Here, the cord-shaped heater 56 is a cord-shaped heater. The cord-shaped heater is formed by winding a heating wire 59 such as a nickel-chromium wire at equal intervals on a core material 58 such as glass fiber, and then using polychloride Insulating coating materials 60 and 61 such as ethylene are double-coated. In addition, the cord heater 56 system may also wind the heating wire 59 around the core material 58 at a non-strictly equal interval, and it is only necessary to wind the heating wire 59 around the core material 58 at approximately equal intervals. In addition, instead of the double-sided tape 55, a structure in which the aluminum foil heater 43 is attached to the back side of the surface plate 42 by applying glue may also be adopted.

The installation of the double-opening door of the partition 8 (in this embodiment referred to as the left door 6 of the refrigerator compartment) is to fix the upper hinge member 49 and the lower hinge member 51 of the partition 8 to the left refrigerator compartment door with screws or the like. 6 inner board (not shown). In addition, the total longitudinal length of the longitudinal direction of the partition 8 is shorter than the total longitudinal length of the front opening of the refrigerator compartment 1, and between the upper and lower ends of the partition 8 and the front opening of the refrigerator 1 Form gaps respectively.

Regarding the energization of the aluminum foil heater 43, the control device 29 edits the formula of the energization rate calculation formula, and the energization rate calculation formula is determined by testing in advance. Here, the energization rate is defined by changing the voltage applied to the aluminum foil heater 43 over time. For example, it is defined in the form of energizing for 5 seconds in a predetermined time of 10 seconds, and not energizing for the remaining 5 seconds. In this case, The electrification rate is 50%. The energization rate to the aluminum foil heater 43 is calculated by the control device 29 in response to the outside air temperature, the outside air humidity, and the refrigerating room temperature, and gradually changes in response to the surrounding environment.

The energization rate calculation formula of the program edited by the control device 29 is, for example, energization rate=a×outer air temperature+b. Here, a and b are changed according to the value of A according to the coefficient determined by the value of A = outside air temperature-temperature of the refrigerating compartment. Moreover, the control device 29 responds to the outside temperature sensor 9, the outside humidity sensor 10, and the refrigerator compartment temperature sensor 32 to detect the outside temperature, the outside humidity, and the refrigerator temperature. The arithmetic formula is calculated to determine the energization rate to the aluminum foil heater 43. The determined energization rate is the non-condensing energization rate on the surface of the partition 8, the refrigerator compartment left door 6 and the refrigerator compartment right door 7, or the gaskets 62, 64, etc., that is, the energization rate that improves the condensation resistance of those components and prevents condensation .

Here, the energization rate calculated from the energization rate calculation formula is that the higher the outside air temperature and humidity, the greater the energization rate, and the lower the temperature of the refrigerator compartment 1, the greater the energization rate. Furthermore, the control device 29 energizes the aluminum foil heater 43 at the energization rate determined by calculation. Therefore, if the outside air temperature and humidity are low, and the refrigerating compartment temperature is high, the energization rate can be reduced, so energy efficiency can be improved.

In addition, the structure of the separator 8, the energization method to the aluminum foil heater 43, the energization rate calculation formula, etc. are not limited to the above-mentioned content. For example, the partition plate 8 may also be configured with a surfaceless frame type resin member 44, as long as it can be configured to fill the gap formed above and below the partition plate 8 with the spacer fins 63 and 65.

Next, the structure of the periphery of the upper part of the partition 8 of the refrigerator 100 is demonstrated. Fig. 8 is a perspective view showing part B of Fig. 1. In addition, FIG. 8 shows a state where the left door 6 of the refrigerating compartment is closed, and the state where the right door 7 of the refrigerating compartment is opened. In addition, the one-dot chain line in FIG. 8 shows the outer shape of the gasket fin 65 attached to the right door 7 of the refrigerator compartment when the right door 7 of the refrigerator compartment is closed.

As shown in FIG. 8, the partition 8 is installed on the inner panel of the left door 6 of the refrigerator compartment by means of an upper hinge member 49 and a lower hinge member 51 so as to be rotatable about a vertical axis. Therefore, when the right door 7 of the refrigerating compartment is opened, the position of the partition plate 8 remains in the original state. In addition, to the left door 6 of the refrigerator compartment and the right door 7 of the refrigerator compartment, the front flange part 70 around the front opening part of the refrigerator compartment 1 and the gaskets 62 and 64 which are in close contact with the partition 8 are respectively attached. The gaskets 62 and 64 are attached to the end portions of the refrigerator inner side surface of the refrigerator compartment left door 6 and the refrigerator compartment right door 7, and are provided all around. That is, the spacers 62 and 64 have a quadrangular shape, and are composed of an upper lateral side, a lower lateral side, a left longitudinal side, and a right longitudinal side. Moreover, in the state where both the left door 6 of the refrigerator compartment and the right door 7 of the refrigerator compartment are closed, the right longitudinal side of the gasket 62 and the left longitudinal side of the gasket 64 are in close contact with the partition plate 8, and the rest of the gaskets 62 and 64 The three sides are in close contact with the flange portion 70 on the front face of the refrigerator compartment 1.

In addition, shim fins 63 and 65 are provided on the upper and lower portions of the right longitudinal side of the gasket 62 and the upper and lower portions of the left longitudinal side of the gasket 64, respectively. Furthermore, in the state where both the left door 6 of the refrigerator compartment and the right door 7 of the refrigerator compartment are closed, the spacer fins 63 and 65 are in close contact with the partition plate 8 and the front flange portion 70 of the refrigerator compartment 1 to block the upper gap 66 and the lower gap 67 (refer to Figure 10 described later).

Between the upper end of the partition plate 8 and the upper surface of the refrigerating compartment 1, an upper gap 66 is formed. Furthermore, in the state where both the left door 6 of the refrigerating compartment and the right door 7 of the refrigerating compartment are closed, the left and right shim fins 63 and 65 overlap, and the upper gap 66 is blocked by the shim fins 63 and 65. In addition, in FIG. 8, only the upper gap 66 is shown, but a lower gap 67 is also formed between the lower end of the partition plate 8 and the bottom surface of the refrigerator compartment 1. In addition, the lower gap 67 is the same. In a state where both the left door 6 of the refrigerating compartment and the right door 7 of the refrigerating compartment are closed, the left and right shim fins 63, 65 overlap and are blocked by the shim fins 63, 65.

Here, the upper gap 66 and the lower gap 67 blocked by the spacer fins 63 and 65 are not provided with the heat insulating material 45 or the like. Therefore, when the aluminum foil heater 43 is energized, the temperature of the shim fins 63, 65 that also block the upper gap 66 and the lower gap 67 is harder to rise than the central portion of the shim 62, 64, and the condensation resistance is lower. Therefore, in the past, in order to avoid condensation on the spacer fins 63 and 65, it was necessary to increase the energization rate to the aluminum foil heater 43 in the separator 8 beyond necessary. Here, as shown in FIG. 5, generally, the upper side of the refrigerator compartment 1 has a large heat leakage 33 from the top surface 69 of the refrigerator 100. Therefore, as the air volume blown out from the blowing outlets 37 to 41 formed on the deep side wall of the refrigerating compartment 1, the parts in the refrigerating compartment 1 divided by the plurality of shelves 30 are made so that the air volume at the uppermost stage becomes maximum. Furthermore, since the temperature distribution of each part divided in the refrigerator compartment 1 is made to be within a certain width, the upper part of the partition 8 tends to be cooled more easily than the lower part.

On the other hand, the surface temperature of the shim fins 63 and 65 that plug the upper gap 66 tends to be more difficult to rise than the surface temperature of the shim fins 63 and 65 that plug the lower gap 67. Therefore, the energization rate to the aluminum foil heater 43 is determined in accordance with the surface temperature of the spacer fins 63 and 65 that plug the upper gap 66. Here, since the upper gap 66 blocked by the spacer fins 63 and 65 is not provided with a heat insulating material 45 or the like, the temperature of the spacer fins 63 and 65 is determined based on the temperature of the upper gap 66. Therefore, if the temperature of the upper gap 66 can be increased, the surface temperature of the shim fins 63 and 65 will rise, and the energization rate that is increased beyond necessary can be reduced, and energy efficiency can be improved. Therefore, the structure of this part is explained in detail below.

Figure 9 is a cross-sectional arrow view of Figure 1 AA. In addition, in FIG. 9, the left door 6 of the refrigerating compartment and the right door 7 of the refrigerating compartment are omitted from the drawings, and with the partition 8 as the boundary, the left side is the outside of the refrigerator and the right side is the inside of the refrigerator.

As shown in Fig. 9, on the lower front portion of the top surface 69 of the refrigerator 100, a guide member 71 for rotating the partition 8 is installed, and the guide member 71 is provided with a protrusion 72 protruding downward. This protrusion 72 is linked to the opening and closing of the left door 6 of the refrigerating compartment. When the left door 6 of the refrigerating compartment is opened, one side abuts against the groove 73 formed on the upper cover member 48 so as to follow the inner plate of the left door 6 of the refrigerating compartment. The way makes the partition 8 rotate. When the partition 8 rotates, the spring 52 provided on the lower hinge member 51 and the protrusion 72 provided on the guide member 71 cause the partition 8 to move as shown below. When the left refrigerating compartment door 6 is opened, the partition 8 protruding portion 72 abuts the groove 73 formed in the upper cover member 48 and rotates along the inner panel of the left refrigerating compartment door 6. On the other hand, when the left door 6 of the refrigerating compartment is closed, the partition 8 is rotated to block the gap between the left door 6 of the refrigerating compartment and the right door 7 of the refrigerating compartment. In addition, in the state where both the left door 6 of the refrigerating compartment and the right door 7 of the refrigerating compartment are closed, the left and right shim fins 63 and 65 overlap, and the upper gap 66 is blocked by the shim fins 63 and 65.

The pattern 74 on the uppermost part of the aluminum foil heater 43 in the partition plate 8 is arranged so as to come to a position projected on the spacer fins 63 and 65 in the height direction. This is to make the uppermost pattern 74 of the aluminum foil heater 43 as close to the upper gap 66 as possible, so that the temperature of the upper gap 66 can easily rise. In addition, the pattern (not shown) of the lowermost part of the aluminum foil heater 43 in the partition plate 8 is also provided so as to reach a position projected on the spacer fins 63 and 65 in the height direction.

In addition, only the upper gap 66 is shown in Fig. 9, and the lower gap 67 between the lower end of the partition plate 8 and the bottom surface of the refrigerator compartment 1 (refer to Fig. 10 described later) is also the same. The left and right shim fins 63, 65 overlap, and Use washer wings 63 and 65 to plug it. However, on the lower surface side of the refrigerator compartment 1, the guide member 71 and the protrusion 72 are not provided, and the groove 73 is not formed in the lower cover member 50.

Next, the pattern of the cord heater 56 of the aluminum foil heater 43 provided in the partition 8 will be described. 10 is a diagram showing the pattern of the cord heater 56 of the aluminum foil heater 43 provided in the partition 8 when the periphery of the partition 8 of the refrigerator 100 of the present embodiment is viewed from the front. Fig. 11 is an enlarged view of part C of Fig. 10. Fig. 12 is an enlarged view of part D of Fig. 10. Figure 13 is an enlarged view of part E of Figure 10. Fig. 14 is a view of the horizontal cross-section of the upper portion 75 of the partition plate 8 of the refrigerator 100 of the present embodiment viewed from above. Fig. 15 is a view of the horizontal cross-section of the central part 76 of the partition plate 8 of the refrigerator 100 of the present embodiment viewed from above. In addition, in FIGS. 10-13, the pattern of the aluminum foil heater 43 is shown by the through spacers 62 and 64. In addition, the dotted lines in FIGS. 10 to 13 indicate the magnets 81 and 82. In addition, the one-dot chain line in FIGS. 10 to 13 indicates the center position 86 of the partition 8 in the left-right width direction.

Here, magnets 81 and 82 are provided in the pads 62 and 64 on the left and right. Because the magnets 81 and 82 are attached to the metal front flange portion 70 when the left refrigerator door 6 and the right refrigerator door 7 are closed, the left refrigerator door 6 and the right refrigerator door 7 are connected to the front flange of the refrigerator room 1. Section 70 is tightly connected. In addition, the magnets 81 and 82 have high thermal conductivity.

In the following, as shown in FIG. 10, the partition 8 is divided into three parts of an upper part 75, a central part 76, and a lower part 77 in the longitudinal direction of the longitudinal direction. The upper part 75 is the part that is in close contact with the shim fins 63 and 65 that close the upper gap 66, the lower part 77 is the part that is in close contact with the shim fins 63 and 65 that close the lower gap 67, and the central part 76 is between the upper part 75 and the lower part 77. Part of the time.

In the present embodiment, the cord heater 56 has a tether shape and is formed by winding a heating wire 59 on a core material 58 such as glass fiber at equal intervals in the longitudinal direction so that the heating density becomes a constant value. . Therefore, in order to increase the heat generation density of the surface of the partition 8 in the parts in close contact with the gasket fins 63 and 65, which have a high risk of condensation, it is necessary to lay many heater patterns. Therefore, as shown in FIGS. 11 and 14, on the upper part 75 of the partition plate 8, the pattern width of the lanyard heater 56 (hereinafter referred to as the upper pattern width a) is laid in the left and right spacers 62, 64 The distance between the outer side surfaces of the magnets 81 and 82 to be installed is greater than the distance c between the outer side surfaces. Here, the outer side surfaces of the magnets 81 and 82 are side surfaces that are not opposed to each other among the side surfaces of the magnets 81 and 82 in the left-right direction. Also, as shown in FIG. 13, in the lower portion 77 of the partition plate 8, the pattern width of the lanyard heater 56 (hereinafter referred to as the lower pattern width b) is laid so as to be installed in the left and right spacers 62, 64 The distance between the outer sides of the magnets 81 and 82 is greater than the distance c between the outer sides.

In addition, since the upper part of the refrigerating compartment 1 has a larger air volume than the lower part and is easier to be cooled, the upper pattern width a of the cord heater 56 may be made wider than the lower pattern width b. That is, the upper pattern width a of the cord heater 56> the lower pattern width b of the cord heater 56 ≥ the distance c between the outer surfaces.

Here, the magnets 81, 82 provided in the left and right spacers 62, 64 are substantially straight in the longitudinal direction of the refrigerator 100, and the distance c between the outer surfaces is the same from top to bottom. On the upper part 75 and the lower part 77 of the partition plate 8, the cord heater 56 is laid so that the distance between the outer sides of the magnets 81 and 82 is greater than the distance c between the outer sides. In this way, the temperature of the magnets 81 and 82 themselves provided in the parts of the spacers 62 and 64 that are in close contact with the upper part 75 and the lower part 77 of the spacer 8 can be further increased. Therefore, the temperature of the magnets 81 and 82 can be further increased at the portions of the gaskets 62 and 64 facing the cord heater 56. Furthermore, due to the heat conduction in the magnets 81 and 82 with relatively high thermal conductivity, the sum of the spacers 62 and 64 is the part where the upper gap 66 is opposed to the upper part 75 of the partition plate 8, and the magnets 81 and The temperature of 82 is rising. Therefore, the temperature of the shim fins 63 and 65 that plug the upper gap 66 can be increased.

In the central part 76 of the partition 8, because there is no gap between the upper part 75 and the lower part 77 and the refrigerator at the back, that is, there is heat insulation, so the risk of condensation is lower than that of the upper part 75 and the lower part 77. Therefore, since the heat invaded into the refrigerator is reduced, as shown in FIGS. 12 and 15, the pattern width of the lanyard heater 56 at the central part 76 of the partition plate 8 (hereinafter referred to as central part pattern width d) It is laid so as to be within the distance e between the inner surfaces of the magnets 81, 82 provided in the left and right spacers 62, 64. Here, the inner side surfaces of the magnets 81 and 82 are side surfaces on the sides facing each other among the side surfaces of the magnets 81 and 82 in the left-right direction. That is, the pattern width d of the central portion of the cord heater 56 ≤ the distance e between the inner surfaces.

Here, as described above, since the magnets 81, 82 provided in the left and right spacers 62, 64 are substantially straight in the longitudinal direction of the refrigerator 100, the distance e between the inner surfaces is the same from top to bottom.

As shown above, the width of the pattern of laying the cord heater 56 is changed according to the position in the partition 8, thereby changing the longitudinal heat density of the surface of the partition 8, so that the upper pattern width of the cord heater 56 A and the lower pattern width b are wider than the central pattern width d. That is, the upper pattern width a of the cord heater 56> the lower pattern width b of the cord heater 56> the central pattern width d of the cord heater 56. In this way, the heat generation density of the surface of the partition 8 is increased in the upper portion 75 and the lower portion 77 than in the central portion 76.

Fig. 16 is a view of the upper part 75 of the modified example of the partition plate 8 of the refrigerator 100 of the present embodiment viewed from above in a transverse section. Fig. 17 is a view of a transverse cross-section of the central part 76 of the modified example of the partition plate 8 of the refrigerator 100 of the present embodiment viewed from above.

In this embodiment, the pattern width of the cord heater 56 includes the thickness of the insulating coating. That is, the pattern width of the cord heater 56 is as shown in FIG. 14. The upper part 75 and the lower part 77 of the partition plate 8 also include the insulating coating and become the distance c between the outer surfaces, as shown in FIG. The central portion 76 of the partition plate 8 also includes the insulating coating and becomes within the distance e between the inner surfaces. In this way, the thickness of the insulating coating is included in the pattern width of the cord heater 56, which is effective for heat transfer to the magnets 81 and 82 with relatively large thermal conductivity. However, due to arrangement restrictions, etc., the thickness of the insulating coating may not be included in the pattern width of the cord heater 56. That is, as shown in Figs. 16 and 17, the above-mentioned effect can be obtained to some extent by using the pattern width of the cord heater 56 as the distance between the left and right center lines.

18 is a diagram showing the pattern of the cord heater 56 of the aluminum foil heater 43 provided in the partition 8 when the periphery of the partition 8 of the modified example of the refrigerator 100 of this embodiment is viewed from the front. Figure 19 is an enlarged view of part C of Figure 18. Fig. 20 is an enlarged view of part D of Fig. 18. Fig. 21 is an enlarged view of part E of Fig. 18. In addition, in FIGS. 18-21, the pattern of the aluminum foil heater 43 is shown by the through spacers 62 and 64. In addition, the broken lines in FIGS. 18 to 21 indicate the magnets 81 and 82. In addition, the one-dot chain line in FIGS. 18-21 shows the center position 86 of the partition 8 in the left and right width direction.

Because the pattern width of the cord heater 56 changes within the partition 8, the shape of the aluminum foil 54 that fixes the cord heater 56 can also be changed in a tracking manner. In this case, as shown in FIGS. 18 to 21, the width of the aluminum foil 54 is widened at the upper part 75 and the lower part 77 of the partition 8, and the width of the aluminum foil 54 is narrowed at the central part 76 of the partition 8. That is, the width of the upper portion of the aluminum foil 54 (hereinafter referred to as the upper width f), the width of the central portion of the aluminum foil 54 (hereinafter referred to as the central portion width g), and the width of the lower portion of the aluminum foil 54 (hereinafter referred to as the lower width h) The relationship is that the upper width f of the aluminum foil 54> the lower width h of the aluminum foil 54> the central portion width g of the aluminum foil 54.

Also, in the same way, the shape of the surface plate 42 may be changed. In this case, as shown in FIGS. 18 to 21, the width of the surface plate 42 is widened at the upper portion 75 and the lower portion 77 of the partition 8, and the width of the surface plate 42 is narrowed at the central portion 76 of the partition 8. That is, the width of the upper part of the surface sheet metal 42 (hereinafter referred to as upper width i), the width of the central part of the surface sheet metal 42 (hereinafter referred to as the center width j), and the width of the lower part of the surface sheet metal 42 (hereinafter referred to as the lower width The relationship of k) is that the upper width i of the surface sheet metal 42>the lower width k of the surface sheet metal 42>the central part width j of the surface sheet metal 42.

In addition, in the part where the width of the surface sheet metal 42 changes, especially by narrowing the width j of the center portion, the heat intrusion into the refrigerator is reduced, so the energy efficiency is higher. However, considering the adhesion to the spacers 62 and 64, the relationship between the width j of the center portion of the surface sheet 42 at this time and the distance e between the inner surfaces, which is the distance between the inner surfaces of the magnets 81 and 82, is set as the surface sheet 42 The width of the central part j≧the distance e between the inner sides.

Here, when considering heat conduction to the magnets 81, 82 provided in the left and right spacers 62, 64, etc., the pattern width (a, b, d) of the cord heater 56 and the gap between the magnets 81 and 82 The distance (c, e), the width (f, g, h) of the aluminum foil 54 and the width (i, j, k) of the surface sheet metal 42 are preferably arranged so that the respective center positions are consistent. For example, after satisfying the above-mentioned relationship, the cord heater 56 arranged on the upper part 75 of the partition plate 8 is arranged to be biased to one of the left and right, and the cord heater at the portion facing the magnets 81 and 82 The longitudinal length of 56 is the same. However, in this case, the left or right parts of the magnets 81 and 82 are wastefully heated and become a heat load on the refrigerator. When the heat load in the refrigerator increases, this amount of cooling energy is consumed, so energy efficiency is improved. Go low.

In addition, regarding the boundary position between the upper part 75 and the central part 76 of the partition plate 8, and the boundary position between the central part 76 and the lower part 77, it is considered to ensure sufficient magnets 81, 82 provided in the left and right spacers 62, 64. The temperature rise requires a certain degree of ratio between the upper part 75 and the lower part 77 of the partition plate 8. Therefore, the partition 8 is the longitudinal length in the longitudinal direction. From the upper end of the partition 8 to the downward direction, approximately 10% of the total length is taken as the upper part 75, and from the lower end of the partition 8 to the upward direction, approximately 10% of the total length As the lower part 77, the middle part 76 is defined between the upper part 75 and the lower part 77. However, the longitudinal length of the upper gap 66 and the lower gap 67 affects the temperature of the spacer fins 63 and 65. For example, it is considered that the longer the longitudinal length of the upper gap 66 and the lower gap 67 is, the temperature of the shim fins 63 and 65 will hardly rise if there is no more heat generation. Therefore, when the longitudinal lengths of the upper gap 66 and the lower gap 67 are long, for example, 5 mm or more, the ratio of the upper portion 75 to the lower portion 77 of the partition plate 8 needs to be slightly larger than the above-mentioned value. In addition, in this embodiment, the longitudinal lengths of the upper gap 66 and the lower gap 67 are both about 2 mm, the cord heater 56 is about 11.1 W, and 10% from the upper and lower end surfaces of the partition plate 8 is used as the upper portion 75 and The lower part 77.

As mentioned above, the refrigerator 100 of this embodiment includes: left and right double-opening doors that open and close the front opening of the refrigerator compartment 1; and a partition 8, which is installed on one of the left and right double-opening doors so as to be rotatable and prevent Outside air invades the refrigerator compartment 1. In addition, the refrigerator 100 has gaskets 62 and 64 which are provided on the double-opening door and are in close contact with the partition 8. In addition, gaps are formed between the upper end of the partition 8 and the upper surface of the refrigerating compartment 1, and between the lower end of the partition 8 and the lower surface of the refrigerating compartment 1, respectively. In addition, the separator 8 has a cord heater 56 inside. The cord heater 56 is composed of a heating wire 59 wound around a core material 58 at equal intervals, and is formed from an upper portion 75 to a lower portion 77 in the vertical direction. pattern. In addition, the spacers 62 and 64 have spacer fins 63 and 65, which are provided at the upper and lower parts to close the gap, and magnets 81 and 82, which are installed inside from the upper part to the lower part in the vertical direction. In addition, the pattern width of the cord heater 56 on the upper part 75 and the lower part 77 of the partition plate 8 is greater than the distance between the outer side surfaces of the left and right magnets 81 and 82.

According to the refrigerator 100 of this embodiment, the pattern width of the cord heater 56 on the upper part 75 and the lower part 77 of the partition 8 is greater than the distance between the outer side surfaces of the left and right magnets 81 and 82. Therefore, the temperature of the upper and lower parts of the magnets 81 and 82 easily rises, and the temperature of the shim fins 63 and 65 provided on the upper and lower parts of the shims 62 and 64 can also rise. As a result, the condensation resistance of the spacer wings 63 and 65 can be improved. In addition, the cord heater 56 is formed by winding the heating wire 59 around the core material 58 at equal intervals. Since the winding pitch width of the heating wire 59 is not changed in the longitudinal direction, the manufacturing cost and manufacturing efficiency can be improved.

In addition, in the refrigerator 100 of this embodiment, the pattern width of the cord heater 56 in the central portion 76 between the upper portion 75 and the lower portion 77 of the partition 8 is the distance between the inner surfaces of the left and right magnets 81 and 82 Within the distance e between the inner sides.

According to the refrigerator 100 of the present embodiment, the pattern width of the cord heater 56 in the central portion 76 of the partition 8 is within the distance e between the inner surfaces of the left and right magnets 81 and 82. Therefore, in the central portion 76 of the partition plate 8 where the risk of condensation is low, it is possible to reduce the heat intruding into the refrigerator.

Furthermore, in the refrigerator 100 of this embodiment, the pattern width of the cord heater 56 at the upper portion 75 of the partition 8 is wider than the pattern width of the cord heater 56 at the lower portion 77 of the partition 8.

According to the refrigerator 100 of the present embodiment, the pattern width of the cord heater 56 at the upper portion 75 of the partition 8 is wider than the pattern width of the cord heater 56 at the lower portion 77. Therefore, the condensation resistance of the upper shim fins 63 and 65 can be improved more than that of the lower shim fins 63 and 65. The upper part of the refrigerator compartment 1 can be easily cooled due to the larger air volume than the lower part, which can also suppress Condensation of gasket fins 63 and 65.
