Description

The present invention relates to a refrigerator-freezer, and more particularly to a structure of a partition plate provided on a door of the refrigerator-freezer.

In recent years, in order to realize optimal operation of freezer-refrigerators, the number of freezer-refrigerators equipped with detection devices such as a room temperature sensor and a humidity sensor is increasing according to the environment in which the refrigerator-freezer is installed. Since the amount of heat leakage of the boxes that make up the refrigerator/freezer is fixed, an inverter control device that changes the compressor speed or the fan speed for cooling the inside of the refrigerator is installed and the refrigeration capacity is adjusted according to the ambient temperature. There is a refrigerator. In addition, a refrigerator/freezer in which the door of the refrigerating room is divided into left and right is provided with a partition plate equipped with a heater between the left and right doors to adjust the surface temperature of the partition plate according to the ambient room temperature and humidity. In addition, there are refrigerators and refrigerators in which energization to the heater is changed at a time ratio to improve energy saving.

At this time, the calorific value of the heater inside the partition plate attached to the door of the refrigerating room is determined by the resistance value of the heater and the resistance value of the heater so that the outer surface of the compartment and the gasket of the refrigerating room door located around the partition plate do not generate dew. The arrangement pattern is set. For example, a refrigerator has been proposed in which a plurality of parts having different heat generation amounts are used as a single heating element as a heating means, and the heat generation amount at the central portion is larger than at both end portions in the longitudinal direction of the rotary partition body (Patent Document 1). 1). Further, a refrigerator has been proposed in which the arrangement pattern of the heaters arranged in the partition plate is adjusted in a zigzag manner in the longitudinal direction, and the heat generation amount in the upper region of the heater is set smaller than in the regions other than the upper region. (See Patent Document 2).

Japanese Patent No. 5919582 JP, 2005-148366, A

In a conventional refrigerator, when dew condensation occurs not only on the partition plate provided on the refrigerator door but also on the outside surface of the refrigerator, the dew size gradually decreases with time even if the dew size is small at first. The particle size of dew becomes large, and the dew drops eventually due to the balance between surface tension and gravity. If the falling dew reaches the floor surface and accumulates, it may rot the floor surface. Therefore, it is desirable that the refrigerator is not exposed to dew under any environmental conditions.

If the amount of heat generated by the heater in the partition plate is increased, the concern about dew condensation on the refrigerator can be eliminated, but the energy saving performance of the refrigerator may be deteriorated. For this reason, in the design of the heater in the partition plate, various proposals have been made regarding specifications of the partition plate and the heater so that dew does not occur and energy saving is enhanced. For example, there is a refrigerator in which the heat generation density of the partition plate is changed, or a refrigerator in which an ambient temperature sensor and a humidity sensor are mounted and electric power is controlled according to the ambient temperature and humidity.

The partition plate is usually attached to one of the left and right refrigerating compartment doors, the upper and lower parts of which are fixed by hinges, and a guide (projection) on the upper part of the refrigerating compartment is used to open and close the refrigerating compartment door. A moving structure is adopted. At this time, in order to rotate the partition plate, the length in the longitudinal direction of the partition plate is made shorter than that of the inner wall of the refrigerating compartment, and the partition is provided with a certain gap between the inner wall of the refrigerating compartment and the partition plate. A board is installed. Then, seals are attached to the upper and lower parts of the gaskets of the left and right refrigerating compartment doors so as to close the gap between the inner wall of the refrigerating compartment and the partition plate, and when the refrigerating compartment door is closed, the left and right gasket seals overlap each other. And it is closing the gap. Therefore, the insides of the upper and lower sealing parts are directly exposed to the cool air in the refrigerating chamber, and the temperature thereof is relatively likely to be lower than the surface of the partition plate, which may cause dew condensation. Since raising the temperature of the gasket seal that closes the gap between the upper and lower parts of the partition plate and the refrigerator body is highly reliable against dew condensation, the heat generation density of the heater installed inside the partition plate and the seal part The partition plate must be designed taking into account the temperature and the temperature. Here, some of the heaters arranged in the partition plate are fixed to the aluminum foil with double-sided tape, and the heater wire is bent at the upper and lower ends in the longitudinal direction of the heater. Even if it is attached inside the partition plate, it may come off and rise due to repeated energization. When the heater is peeled off from the partition plate and floats up, the heat generated in the seal portion is weakened, which may increase the possibility that the refrigerator is exposed to dew.

The present invention is for solving the above problems, and an object of the present invention is to provide a refrigerator-freezer in which the upper and lower ends of the heater in the partition plate do not float.

The refrigerator-freezer according to the present invention has a refrigerator main body having a storage chamber, a plurality of doors provided on the front surface of the refrigerator main body to open and close the storage chamber, and a gap located at the boundary between a plurality of adjacent doors. A partition plate to be closed, and a seal member provided on a plurality of adjacent doors and covering a gap formed between the upper and lower end portions of the partition plate and the refrigerator body, the partition plate facing the seal member, And, a surface sheet metal facing the back surface side of a plurality of adjacent doors, a heater arranged along the extending direction of the surface sheet metal, for heating the surface sheet metal, and a surface frame type member for housing the heater, The heater has an upper bent portion and a lower bent portion where the heater wire bends at the upper end and the lower end of the partition plate, respectively, and the surface frame-shaped member has the upper end and the lower end of the partition plate. Each has a heater pressing part, and the upper end bent part and the lower end bent part are arranged between the surface sheet metal and the heater pressing part.

According to the present invention, the surface frame-shaped member that accommodates the heater has the heater pressing portions at the upper end and the lower end, respectively, and the upper bent portion and the lower bent portion of the heater wire are the surface sheet metal and the heater pressing member. It is the one that is placed between. Therefore, in the refrigerator-freezer, the heater pressing member arranged behind the heater regulates the movement of the heater between the surface sheet metal and the surface frame-shaped member, and the upper and lower ends of the heater arranged on the partition plate are separated from each other. You can prevent it from rising.

Is rotated, and the back member 26 and the inner plate of the refrigerating compartment left door 7 face each other. Alternatively, when the refrigerating compartment right door 8 provided with the partition plate 9 is opened, the partition plate 9 is rotated along the inner plate of the refrigerating compartment right door 8 by the spring 32 attached to the lower hinge member 29. Then, the back member 26 and the inner plate of the refrigerating room right door 8 face each other.

Since the upper guide member 15 is guided by the projecting portion 52 of the guide part 51 inserted into the groove portion 15a when the refrigerating compartment left door 7 provided with the partition plate 9 is closed, the partition plate 9 is refrigerated. It rotates about the hinge fixing with the inner plate of the left door 7. Alternatively, since the upper guide member 15 is guided by the protrusion 52 of the guide part 51 inserted into the groove 15a when the refrigerating room right door 8 provided with the partition 9 is closed, It rotates about the hinge fixing to the inner plate of the refrigerating room right door 8.

(Surface sheet metal 22)
The front surface metal plate 22 is, for example, a plate-shaped metal extending in one direction (Z axis direction), and the center in the width direction (X axis direction) is provided at the boundary between the refrigerating compartment left door 7 and the refrigerating compartment right door 8. It coincides with the center of the gap. When the refrigerating compartment left door 7 and the refrigerating compartment right door 8 are closed, the surface sheet metal 22 faces the upper left sealing material 17 or the upper right sealing material 18, and is adjacent to the refrigerating compartment left door 7 and the refrigerating compartment. It faces the back side of the room right door 8. Further, when the refrigerating compartment left door 7 and the refrigerating compartment right door 8 are closed, the surface sheet metal 22 faces the lower left sealing material 19 or the lower right sealing material 20, and is adjacent to the refrigerating compartment left door. 7 and the back side of the refrigerating room right door 8 are opposed. The surface sheet metal 22 transfers heat from the heater 23 to the refrigerating compartment left door 7, the refrigerating compartment right door 8, the gasket 16, the upper left sealing material 17, the upper right sealing material 18, the lower left sealing material 19 and the lower right sealing material 20. Is. The front surface metal plate 22 conducts heat generated by the heater 23, so that the partition plate 9, the refrigerating compartment left door 7, the refrigerating compartment right door 8, the gasket 16, the upper left sealing material 17, the upper right sealing material 18, the lower left sealing material 19 and Dew condensation of the lower right sealing material 20 is suppressed. The surface sheet metal 22 also has a function of improving the strength of the aluminum foil 23b in the heater 23 described later. Further, as described above, the surface sheet metal 22 is in close contact with the gasket 16 when the refrigerating compartment left door 7 and the refrigerating compartment right door 8 are closed. As a result, leakage of cold air from the inside of the refrigerator/freezer 100 to the outside of the refrigerator/freezer 100 is suppressed. Further, as described above, the partition plate 9 is attached to the refrigerating compartment left door 7 or the refrigerating compartment right door 8 such that the front surface metal plate 22 is farthest from the refrigerating compartment 1 in the stacking direction (Y-axis direction). In this way, by separating the front surface metal plate 22 from the refrigerating chamber 1, it becomes difficult for the heat of the heater 23 transferred to the front surface metal plate 22 to be transferred to the refrigerating chamber 1, and an increase in the temperature inside the refrigerating chamber 1 is suppressed. ..

The surface metal plate 22 includes a rectangular plate-shaped base portion 22a, fixed portions 22b provided at both ends of the base portion 22a in the longitudinal direction, and flange portions provided at both side portions of the base portion 22a in the lateral direction (X-axis direction). 22c. The surface sheet metal 22 includes a plurality of engaging portions 22d provided on the flange portion 22c on one side (X1) in the lateral direction (X axis direction) of the base portion 22a and a flange portion on the other side (X2). 22c is provided with a plurality of cut-and-raised parts 22e.

The fixed portion 22b has an inverted trapezoidal shape that extends from both ends in the longitudinal direction (Z-axis direction) of the base portion 22a toward the refrigerator compartment 1 while gradually narrowing its width.
