Description

refrigerator

This invention relates to the refrigerator which closed the front opening of the storage room provided in the upper part of the main body in the double doors type with the left and right doors arranged side by side.

Home-use large-capacity refrigerators are commercialized as refrigerators with many doors in each storage room along with diversification of cooling storage temperature to meet various user needs. There are top freezer type with the freezer compartment at the top, middle freezer type with the freezer compartment between the upper refrigerator compartment and the lower vegetable compartment, and the bottom freezer type with the freezer compartment at the bottom. It has been commercialized. Furthermore, forms such as a type in which a vertically long freezer room and a vegetable room are juxtaposed below the upper refrigerator compartment, and a side-by-side type in which a freezer compartment and a refrigerator compartment are juxtaposed on the left and right have been commercialized.

In such a product environment, in recent years, considering ease of use, a refrigerator room that is frequently used and has the largest storage capacity has been placed at the top as a double door, and an ice making room and a temperature switching room are located below it. Refrigerators with a vegetable compartment below and a freezer compartment at the bottom are the mainstream. In this type of refrigerator, a partition that turns 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 so as to provide an adsorption surface for the gasket.

Furthermore, in the case of the double doors in recent refrigerators, the doors are enlarged and the longitudinal dimensions are long, and there are problems in the design of the outer surface due to the curved long partition in the longitudinal direction. In order to solve the problem, a partition plate made of a thin steel plate that forms the suction surface of the door gasket of the rotating partition is first overlapped by folding the flat suction surface and its both side edges inward. Further, it is bent inward to have a shape having an angle portion, and 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. In addition, a configuration in which the partition plate is engaged and held by the partition frame body, and a surface heater is attached to the inner surface of the partition plate to prevent condensation generated on the surface of the partition plate is widely used (see, for example, Patent Document 1). .

Hereinafter, the specifications of the conventional rotary partition of the refrigerator will be described with reference to FIGS. 11 and 12.

FIG. 11 shows a configuration of a double door type door in the refrigerator storage room 3 of the conventional refrigerator. The rotary partition 13 is configured such that the left door 7 and the right door 8 are closed, the door gasket 11 of the left door 7 and the right door. 8 door gasket 12 is adsorbed.

The basic structure of the rotating partition 13 includes a partition plate 16 made of a thin steel plate, which is a magnetic body that forms an attracting surface, a molded heat insulating member 18 made of polystyrene foam that forms a heat insulating layer, and the rotating partition 13 that covers these components. A partition frame 17 made of synthetic resin that forms the outer shell, a surface heater 19 (heating unit) made of an aluminum foil heater or the like disposed on the inner surface of the partition plate 16, and an upper end of the rotary partition 13 are arranged. And a cap member 58 having a guide groove formed on the upper end surface.

Generally, in the above configuration, since the steel plate partition plate 16 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 main body in order to prevent leakage.

Further, the cap member 58 for the purpose of fitting the refrigerated storage chamber 3 and the rotary partition 13 also serves to cover and connect the upper ends of the partition plate 16 and the partition frame 17.

However, in the above-described conventional configuration, the

door gaskets

11 and 12 cooled by the temperature effect of the refrigerator compartment which has become a low temperature are in direct contact with the partition plate 16 made of a thin steel plate having a high thermal conductivity. As a result, the surface temperature of the air-released portion of the battery was lowered, the capacity of the surface heater was increased more than necessary, and the amount of power consumption was increased.

This invention solves said subject and aims at providing the refrigerator which can reduce the electric power input to heating parts, such as a heater of a rotary partition.

This invention solves said subject and aims at providing the refrigerator which can reduce the heater capacity | capacitance of a rotary partition.

In the above conventional configuration, the partition plate is made of a non-insulating thin steel plate and has a large area. When an electric part such as a surface heater is affixed to the inner surface, it is necessary to provide a ground wire in consideration of leakage. There is a problem that the configuration is complicated and the cost is high.

This invention solves said subject, and aims at providing the refrigerator which abolishes a ground wire and can attain cost reduction with a simple structure.

The 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. The portion where the left door 102 and the right door 103 are provided is a portion of the refrigerated storage chamber 105, the ice making chamber 106 below the left door 102, and the frozen storage chamber 107 and vegetable compartment 108 below the ice making chamber 106. Has been placed. A switching chamber 109 is provided on the right side of the ice making chamber 106 under the right door 103.

The left door 102 and the right door 103 are each pivotally supported by a hinge part so as to open to the left and right sides, and a rotating partition 200 is provided on the non-pivot side of the left door 102. The rotating partition 200 rotates in accordance with the opening / closing operation of the left door 102. When the door is closed, the non-pivot side of the left door 102 and the right door 103 is closed via the door gasket 110 to be refrigerated. Cold air leakage from the storage chamber 105 to the outside of the refrigerator 100 is prevented.

Here, a heat insulating partition member (not shown) is disposed between the refrigerator compartment 105, the ice making chamber 106, the frozen storage chamber 107, the vegetable compartment 108, and the switching chamber 109. Steel plate covers 501, 502, and 503 are disposed on the front surface, and are closed via door gaskets 110 of the respective storage chamber doors to prevent cold air leakage from the respective storage chambers to the outside of the refrigerator 100.

First, in the conventional configuration, as shown in FIG. 11, the

door gaskets

11 and 12 cooled by the temperature effect of the refrigerated storage chamber 3 having a low temperature are directly applied to the partition plate 16 made of a thin steel plate having high thermal conductivity. By contacting, the surface temperature of the air release part of the partition plate 16 is lowered more than necessary. And in order to make up for the lowered surface temperature to be higher than the dew point temperature, it is necessary to increase the capacity of the surface heater 19. On the other hand, in the case of this Embodiment, the partition plate 210 which forms the adsorption | suction surface 111 of the door gasket 110 of the rotary partition 200 was made from the synthetic resin. Thus, in the graph illustrating the relationship between the energization rate of the heating unit and the surface temperature of the partition plate in FIG. 3, first, under the condition of the same energization rate, the surface temperature of the partition plate 210 in the present embodiment.

In addition, as shown in FIG. 3, the energization rate for maintaining the dew point temperature when the outside air conditions are 30 ° C. and 75% is approximately 40% in the present embodiment, compared with 50% in the conventional example. It can be seen that it can be reduced by 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.

In addition, by disposing the magnetic body 211 so as to face the magnetic body 112 configured in the door gasket 110, it is possible to ensure the basic function of the rotating partition 200, such as adsorption to the door gasket 110. .

As described above, in the present embodiment, the front opening of the storage chamber is closed in a double-split manner with the left door 102 and the right door 103 disposed side by side, and at least one of the left door 102 and the right door 103 is pivoted.

In FIG. 4, as the shape of the inner surface of the partition plate 310, the heating unit 240 disposed in the central portion and the portions where the magnetic body 211 disposed on both sides of the heating unit 240 is in contact with the partition plate 310 are respectively

Recesses

312 and 313 are formed. That is, the thickness is reduced with respect to the basic plate thickness of the partition plate 310, and the heating unit 240 and the magnetic body 211 are fixed to the

recesses

It is about 1K higher than the surface temperature of the partition plate 210 in the first embodiment. Moreover, it turns out that the electricity supply rate for maintaining the dew point temperature when external air conditions are 30 degreeC and 75% can be reduced about 2%. This is because the distance from the heating unit 240 to the surface of the partition plate 310 is small and the thermal resistance is small because the heating unit 240 is fixed in the recess 312.

In addition, since the reduced thickness portion can be limited by forming the recess 312, the basic thickness of the partition plate 310 can be maintained, and the partition plate 310 can be formed without lowering the strength of the structure more than necessary. Therefore, deformation of the rotary partition 200 can be prevented.

In FIG. 6, the adsorption force between the partition plate 310 and the door gasket 110 in the case of the present embodiment is increased as compared with the configuration of the first embodiment of the present invention. This is because the distance between the magnetic body 211 and the magnetic body 112 in the door gasket 110 is reduced by forming the recess 313 in contact with the magnetic body 211.

In addition, since the reduced thickness portion can be limited by forming the recess 313, the basic thickness of the partition plate 310 can be maintained, and without reducing the strength of the structure more than necessary, the partition plate 310 and The deformation of the rotary partition 200 having the partition plate 310 as a constituent element can be prevented.

As described above, in the present embodiment, the inner surface of the partition plate 310 and the arrangement portion of the heating unit 240 are configured to be thinner than the basic plate thickness of the partition plate 310, thereby reducing the thermal resistance. Input to the heating unit 240 can be reduced.

In addition, the partition plate 410 is made of resin, the upper end surface has a degree of freedom, can be engaged with the partition frame 430, and the guide groove 431 is formed on the upper end surface of the partition frame 430. Therefore, a simple configuration can be obtained without using a separate cap.

(Fourth embodiment)
Hereinafter, the refrigerator in the 4th Embodiment of this invention is demonstrated.

The basic configuration of the refrigerator in the fourth embodiment of the present invention is the same as the refrigerator in the first embodiment of the present invention shown in FIGS. 1 and 2, and the refrigerator in the first embodiment of the present invention. Different parts will be explained.

FIG. 8 is a cross-sectional view taken along the line 8-8 in FIG. 2, and shows a cross section of the main part of the rotating partition of the refrigerator in the present embodiment. The heating unit 240 provided in the rotary partition 200 of the refrigerator in the present embodiment is a linear member such as a linear heater, and is arranged between the magnetic members 211 in parallel with the magnetic member 211 as shown in FIG. Is done.

With this configuration, the heating unit 240 is not affected by the arrangement of the magnetic body 211, and the portion of the partition plate 210 that is most likely to condense can be efficiently heated with low thermal resistance. Can do.

(Fifth embodiment)
FIG. 9 is a specific configuration diagram of the heating unit of the refrigerator in the fifth embodiment of the present invention, and FIG. 10 is the heating value of the heating unit in each part of the heating unit of the refrigerator in the fifth embodiment of the present invention. It is a graph explaining the relationship between a partition plate surface temperature. The same components as those in the first to fourth embodiments of the present invention are denoted by the same reference numerals and description thereof is omitted.

In FIG. 9, the heating unit 240 is a linear heater having a length L, and is approximately the same length as the rotary partition 200 of the refrigerator 100 in the first embodiment of the present invention shown in FIG. 1. 2 is disposed at the center of the synthetic resin partition plate 210 shown in FIG. The heating unit 240 has a variable calorific value, that is, a watt density. In FIG. 9, the part a, the part b, and the part c are variable. In addition, as a specific part that makes the heating value of the heater constituting the heating unit 240 variable, 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. This can be achieved by varying the sheet resistance or connecting in series resistance heating wires with different resistance values. In the present embodiment, the heating unit 240 is divided into three parts, a part a, a part b, and a part c, but may be divided into a plurality of parts according to the purpose.

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

First, when the heating unit 240 is not energized, the surface temperature of the partition plate 210 is low at the central part (part b) as shown by the dotted line, and the temperature increases toward both ends (parts a and b). 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. Next, when the heating unit 240 is energized, since the surface temperature of the partition plate 210 is in the dew condensation region, it is necessary to energize the heating unit 240 to raise each part to a temperature higher than the dew condensation boundary line.

At this time, in a heater that is a conventional heating unit with a constant calorific value indicated by a one-dot chain line, since the temperature rise of each part is constant, it is necessary to match the calorific value with the part b having the lowest temperature. For c, an unnecessary temperature increase occurs as shown by the alternate long and short dash line.

On the other hand, in the present embodiment, as shown in FIG. 10, the heating value of the heating unit 240 is variable depending on the part. That is, as indicated by the solid line, the part b increases the amount of heat generation, and the part a and part c decrease. By doing so, the surface temperature (dotted line) of the partition plate 210 without energization to the heating unit 240 can be a uniform surface temperature (solid line) exceeding the dew point boundary line as much as necessary. Compared with the conventional heating value of the heating part, the heating value for the area surrounded by the diagonal line is unnecessary, and the power consumption can be reduced accordingly.

As described above, the present invention provides a rotating partition body that is closed in a double-split manner with the left and right doors in which the front opening of the storage chamber is juxtaposed, and extends vertically on the inner surface of at least one of the left and right doors on the side opposite to the pivot. Provided as the suction surface of the door gasket. In addition, the rotating partition is a partition plate that forms at least an adsorption surface of the door gasket, a heat insulating material disposed inside the rotating partition, a partition frame that covers the peripheral edge of the partition plate and the outer surface of the heat insulating material, And a heating unit disposed on the inner surface of the partition plate. Further, the partition plate and the partition frame body are formed of synthetic resin. With this configuration, condensation on the surface of the partition plate of the rotating partition can be prevented with a minimum of input.

Further, according to the present invention, the magnetic body is disposed on the inner surface of the partition body, so that the adsorbing force between the door gasket and the partition plate can be ensured.

Further, according to the present invention, the magnetic material is arranged at a position facing the magnetic material formed in the door gasket in a state where the left and right doors are closed, so that the door gasket can obtain a good adsorption force.

Further, according to the present invention, the temperature of the surface of the partition plate can be increased by configuring the arrangement portion of the heating portion on the inner surface of the partition plate to be thinner than the basic plate thickness of the partition plate.

Further, according to the present invention, the magnetic material disposed on the inner surface of the partition plate is configured to be thinner than the basic plate thickness of the partition plate, whereby the magnetic force generated on the surface of the partition plate can be enhanced.

Further, according to the present invention, since the heating part is arranged in a straight line, the heating part is not affected by the arrangement of the magnetic body, and the part of the partition plate that is most likely to be condensed in a state of low thermal resistance. Can be efficiently heated, so energy can be saved.

Further, according to the present invention, when there are a plurality of magnetic bodies, the heating section is arranged between the magnetic bodies, so that it is possible to configure a rotating partition body that ensures both adsorption force and surface temperature in a limited space.

Further, according to the present invention, since the heat generation amount, that is, the watt density is made variable by dividing the heating portion into a plurality of parts, the partition plate surface temperature of the rotating partition is made uniform, and thus there is no variation in temperature distribution. The required power input can be reduced.

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. 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.
