Description

The present disclosure relates to refrigerators with double doors.

2. Description of the Related Art In recent years, an increasing number of refrigerators are equipped with a temperature sensor, a humidity sensor, and the like in order to realize optimum operation according to the environment in which the refrigerator is installed. For example, the refrigerating compartment door is divided into left and right, and a heater or the like is installed on the partition plate between the refrigerating compartment doors. Some refrigerators increase energy efficiency by adjusting the surface temperature of the plates.

In addition, the partition plate is usually attached to either the left or right refrigerating compartment door, and its upper and lower parts are hinged to the refrigerating compartment door. A structure that rotates when opening and closing is adopted.

In order to prevent contact between the partition plate and the opening of the refrigerating chamber and allow the refrigerating chamber door to rotate smoothly, the length of the partition plate in the longitudinal direction is made shorter than the height of the opening of the refrigerating chamber. The partition plate is installed so that a certain amount of vertical clearance is formed between the partition plate and the opening of the refrigerator compartment. Gasket fins are provided on the upper and lower parts of the gaskets on the left and right refrigerator compartment doors to close the gap between the top and bottom. It's supposed to be blocked.

Here, the back side of the upper and lower gasket fins is directly exposed to the cold air from the refrigerator compartment, and the upper side of the refrigerator compartment is set so that the air volume is greater than the lower side, so the upper gasket fins are prone to condensation. . In order to prevent dew from forming on the upper gasket fins, the gasket fins should be heated or not cooled. As a means of heating, it is possible to increase the amount of heat generated by the heater in the partition plate. Here, as a means to prevent the gasket fins from being cooled, it is possible to prevent the cold air from the refrigerator compartment from directly hitting the back side of the gasket fins, or to reduce the amount of cold air that hits directly. It is conceivable to reduce the gap between the top surface and the front opening of the refrigerator compartment.

Conventionally, there has been reported a technique for eliminating a gap between a double-sided door and a housing of a refrigerator by controlling the position of the double-sided door when opening and closing it (see, for example, Patent Document 1).

In Patent Document 1, a ball caster is installed on the lower surface near the center of the double-opening door, and when the double-opening door is closed, the ball caster is placed on the front surface of the lower part of the housing of the refrigerator facing the ball caster. Techniques have been reported for laying guide rails to hold the door in place. According to this technology, the double door can be normally closed without leaving a gap between the double door and the housing of the refrigerator.

JP-A-2007-40591

However, in Patent Document 1, it is unclear whether the gap between the upper end surface of the partition plate and the upper front opening of the refrigerating compartment can be reduced when the double hinged door is closed. Ball casters are installed on the lower surface of the partition plate, and guide rails are installed on the floor surface of the refrigerator compartment. There was a problem that it was a hindrance and it was not easy to use.

The present disclosure has been made to solve the above problems, and while reducing the gap between the upper end surface of the partition plate and the upper front opening of the refrigerator compartment when the double door is closed. , to provide a refrigerator capable of suppressing deterioration in usability.

A refrigerator according to the present disclosure includes a housing that forms an outer shell and has a refrigerating chamber inside, a left and right double door that is provided on the front surface of the housing and opens and closes a front opening of the refrigerating chamber, a partition plate rotatably attached to one of the left and right double doors to prevent outside air from entering the refrigerating chamber; wherein the partition plate includes an upper hinge member fixed to the upper side of the inner surface of the double door, a lower hinge member fixed to the lower side of the inner surface of the double door , the upper hinge member and the lower a main body portion supported by a side hinge member and rotated while being guided by the guide member when the double door to which the partition plate is attached is opened and closed, wherein the double door to which the partition plate is attached is In the closed state, the main body moves upward compared to the open state of the double door, and the upper end surface of the main body is in contact with the lower surface of the guide member. be.

According to the refrigerator according to the present disclosure, when the double-door with the partition attached is closed, the main body moves upward compared to when the double-door is open. The upper end surface of the portion is in contact with the lower surface of the guide member. Therefore, when the double door is closed, the gap between the upper end surface of the partition plate and the upper front opening of the refrigerator compartment can be reduced. In addition, since ball casters and guide rails are not required, it is possible to suppress deterioration in usability.

In addition, the wind indicated by arrows 37 to 41 is blown out from each outlet to each part of the inner wall of the refrigeration compartment 1 that is partitioned by the plurality of shelves 30 .

Here, as shown in FIG. 8 , in general, heat (see arrow 33 ) leaks from the ceiling 69 of the refrigerator compartment 1 to the upper side of the refrigerator compartment 1 . Therefore, with respect to the amount of air blown out from the outlet formed in the wall on the back side of the refrigerating chamber 1, the highest air volume is maximized in each portion of the inside of the refrigerating chamber 1 partitioned by the plurality of shelves 30. . Since the temperature distribution of each partitioned portion in the refrigerating chamber 1 is kept within a certain width, the upper portion of the partition plate 8 tends to be cooled more easily than the lower portion.

For this reason, conventionally, the energization rate of the aluminum foil heater 43 in the partition plate 8 has been made higher than necessary so as to prevent dew from forming on the upper gasket fins 63 and 65 . Conventionally, a gap (hereinafter referred to as an upper gap) formed between the upper end surface 72 of the partition plate 8 of the refrigerator and the flat lower surface 73 of the guide member 71 provided on the ceiling 69 of the refrigerator compartment 1 is formed. The surface temperature of the sealing gasket fins 63, 65 tends to be less likely to rise than the surface temperature of the sealing gasket fins 75, 76 closing the lower gap because the air flow is large on the upper side of the refrigerator compartment 1.例文帳に追加Therefore, conventionally, the energization rate to the aluminum foil heater 43 was determined according to the surface temperature of the gasket fins 63 and 65 closing the upper gap.

FIG. 19 is a cross-sectional view of the upper portion of refrigerator 100 shown in FIG. 18 as seen from below. FIG. 20 shows a state in which the refrigerator compartment left door 6 is further closed than in FIG. FIG. 21 shows a state in which the refrigerator compartment left door 6 is closed further than in FIG. Note that FIG. 21 shows a state in which the refrigerator compartment left door 6 is completely closed.

As shown in FIG. 18, a guide member 71 is attached to the center of the front lower portion of the ceiling 69 of the refrigerator compartment 1 to guide the rotation of the main body portion 8a of the partition plate 8 when the left door 6 of the refrigerator compartment is opened and closed. , the guide member 71 is provided with a guide protrusion 110 projecting downward. This guide projection 110 is interlocked with the opening and closing of the left door 6 of the refrigerator compartment, and when the left door 6 of the refrigerator compartment is opened and closed, the guide projection 110 moves toward the left door 6 of the refrigerator compartment while coming into contact with the guide projection guide recess 109 formed in the upper cover member 48 . The body portion 8a of the partition plate 8 is rotated along the inner plate 87 of the partition plate 8. As shown in FIG.

Next, how the partition plate 8 moves according to the opening and closing of the refrigerator compartment left door 6 will be described. When the refrigerator compartment left door 6 is closed from the open state, as shown in FIG. As the left door 6 of the refrigerator compartment is further closed, as shown in FIG. The portion 8a rotates. At this time, the cylinder receiving shape portion 83 moves with respect to the pin 107, and the pin 107 is relatively positioned in the guide groove 108 in the order of the first groove 108a, the third groove 108c, and the second groove 108b, that is, the low groove. moving in the direction of Then, when the refrigerator compartment left door 6 is completely closed, as shown in FIG. 21, the pin 107 is positioned to be accommodated in the second groove 108b. At this time, the second groove 108b is at a lower position than the first groove 108a and the second groove 108b. Since the body portion 8a of the partition plate 8 is pushed upward, the body portion 8a of the partition plate 8 moves upward when the refrigerating compartment left door 6 is changed from the open state to the closed state. and a flat lower surface 73 of a guide member 71 provided on the ceiling 69 of the refrigerating chamber 1 (see FIG. 23, which will be described later). When the refrigerator compartment left door 6 is changed from the closed state to the open state, the operation is reversed.

FIG. 22 is an enlarged view of the portion C of FIG. 17. FIG. In addition, FIG. 22 shows some parts with broken lines so that the internal structure of the lower hinge member 51 of the partition plate 8 can be understood.
Next, the necessity of the spring 102 housed inside the shaft-shaped portion 82 of the lower hinge member 51 will be described. The position of the left door 6 of the refrigerating chamber is lowered due to deterioration over time or food items being stored in the pocket 26 attached to the left door 6 of the refrigerating chamber. lowers against the ceiling 69 of . Therefore, an upper gap is formed between the upper end surface 72 of the partition plate 8 and the flat lower surface 73 of the guide member 71 provided on the ceiling 69 of the refrigerator compartment 1 . Therefore, the position of the body portion 8a of the partition plate 8 is changed by the spring 102 so that the body portion 8a of the partition plate 8 can be moved upward. By doing so, the upper end surface 72 of the partition plate 8 and the flat lower surface 73 of the guide member 71 provided on the ceiling 69 of the refrigerating chamber 1 are in contact with each other, and no upper gap is formed.

In Embodiment 1, the guide groove 108 is formed in the cylinder receiving shape portion 83 provided in the lower portion of the rear side resin member 53 of the partition plate 8, and the pin 107 is positioned midway between the first groove 108a and the third groove 108c. , the pin 107 is positioned at the lower end of the guide groove 108 . Also, when the pin 107 crosses the middle of the third groove 108c, the pin 107 leaves the lower end of the guide groove 108. As shown in FIG. Further, when the pin 107 is in the second groove 108b, the pin 107 is positioned at a position having a slight stroke 111 from the lower end of the guide groove 108. As shown in FIG. This is because the upper end surface 72 of the partition plate 8 contacts the flat lower surface 73 of the guide member 71 provided on the ceiling 69 of the refrigerator compartment 1, and the spring 102 contracts accordingly. Here, the stroke 111 is the gap between the lower end of the pin 107 and the lower end of the second groove 108b.

Even if the position of the refrigerator compartment left door 6 is lowered when the refrigerator compartment left door 6 is closed, the expansion of the spring 102 allows the partition plate 8 to be provided on the ceiling 69 of the refrigerator compartment 1 for this 111 stroke. It can be made to follow and abut on the flat lower surface 73 of the guide member 71 . In addition, the stroke 111 can absorb variations in the mounting position of the partition plate 8 or variations in the overall length of the partition plate 8 . Therefore, the upper end surface 72 of the partition plate 8 and the flat lower surface 73 of the guide member 71 provided on the ceiling 69 of the refrigerator compartment 1 can be brought into contact stably regardless of product variations. This stroke 111 is about 1 mm, and is made smaller than the height difference between the first groove 108a and the second groove 108b, that is, the stroke 114 (see FIG. 16). By doing so, when the main body portion 8a of the partition plate 8 is rotated by opening and closing the left door 6 of the refrigerating chamber, collision with the housing 101 of the refrigerator 100 can be suppressed. Furthermore, when opening and closing the left door 6 of the refrigerator compartment, the upper end surface 72 of the partition plate 8 can be brought into contact with the flat lower surface 73 of the guide member 71 provided on the ceiling 69 of the refrigerator compartment 1 .

Here, regarding the energization of the aluminum foil heater 43, the control device 29 is programmed with an energization ratio calculation formula determined in advance by tests or the like. Here, the energization rate is obtained by changing the voltage applied to the aluminum foil heater 43 with time. , and the energization rate in this case is 50%. The energization rate of the aluminum foil heater 43 is calculated by the control device 29 according to the outside air temperature, the outside air humidity, and the refrigerator compartment temperature, and changes according to the surrounding environment.

An example of an energization rate calculation formula programmed in the control device 29 is energization rate=a×outside air humidity+b. Here, a and b are coefficients determined by the value of A=outdoor temperature−refrigerating chamber temperature, and vary depending on the value of A. Then, the control device 29 calculates the energization rate calculation formula according to the outside air temperature, the outside air humidity, and the refrigerator compartment temperature detected by the outside air temperature sensor 9, the outside air humidity sensor 10, and the refrigerator compartment temperature sensor 32. , the energization rate to the aluminum foil heater 43 is determined. The determined energization rate is such that dew does not form on the surface of the partition plate 8, around the refrigerating chamber left door 6 and refrigerating chamber right door 7, or on the gaskets 62, 64 and gasket fins 63, 65, 75, 76. , that is, the energization rate that improves their resistance to dew and prevents dew condensation.

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