Description

  The present invention relates to a refrigerator.

  In the refrigerator described in Patent Document 1, a magnet is provided inside the packing material, and the magnetic detection sensor 19 for detecting the opening of the refrigerator door is covered with a cover member 20 of a nonmagnetic member (Claim 1, paragraph 0026, FIG. 1). , 2).

JP 2013-190133 A

  In Patent Document 1, the cover member 20 may be visually recognized as a part of the partition member 6 from the opening 5 side of the partition member 6, and there is room for improvement in design. Further, since the magnet 17 inside the packing material 12 (gasket) is not attracted to the cover member 20 which is a nonmagnetic member, the magnet 17 is attracted to maintain contact between the door 10 and the partition member 6 (closed state of the door 10). It is difficult for force to be generated, and there is a possibility that a gap is formed between the two and cold air leaks.

  The cover member 20 is configured to be incorporated in the thickness direction of the partition 6. As an example of a method for performing such assembly, it is conceivable to provide a claw or the like on the cover member 20 and fix it to the partition 6 using this. As an example of a method for suppressing the cold air leakage as described above, it is conceivable that the cover member 20 is made of a magnetic material such as metal. However, a mold or the like is required to manufacture a part having a nail or the like including a metal or the like, which tends to be relatively expensive. For this reason, there is room for improvement in the cover member 20 that houses the magnetic detection sensor 19.

  Further, Patent Document 1 detects the opening / closing of one drawer-type door with one sensor, and does not disclose a method for detecting the opening / closing of two or more doors with one sensor.

  This invention made | formed in view of the said situation, the gasket which has a magnet, the door which can open and close a part or all of front opening of a refrigerator main body, a magnetic sensor, and the slit part which contacts the said gasket at the time of the said door being obstruct | occluded The slit portion includes a front member provided with a magnetic body, and when the door is closed, each of the magnetic sensor, the magnetic body, and the magnet is connected to the refrigerator main body. It is characterized by partly or entirely overlapping in front view.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. Similar components are denoted by the same reference numerals, and the same description will not be repeated.

FIG. 1 is a front perspective view of a refrigerator body 1 according to the present embodiment.
The refrigerator main body 1 is provided with a refrigerator compartment 2, an ice making compartment 3, an upper freezer compartment 4, a freezer compartment 5, a vegetable compartment 6, and doors for closing the openings of the respective storage compartments. The upper freezer compartment door 4a is a door that closes the opening of the upper freezer compartment 4, the ice making chamber door 3a is a door that closes the opening of the ice making chamber 3, the freezer compartment door 5a is a door that closes the opening of the freezer compartment 5, and the vegetable compartment door 6a is a vegetable. It is a door that closes the opening of the chamber 6. Each of these doors closes the opening corresponding to each door by making contact with a squeeze member that partitions the opening of the refrigerator main body 1. Each door has a gasket (not shown) provided with a magnet 35 in the inside thereof to improve contact with the squeeze member. A gasket can be provided, for example along the outer periphery of each door.

  The refrigerator compartment doors 2 a and 2 b are doors that close the opening of the refrigerator compartment 2. The left and right refrigerator compartment doors 2a and 2b are of the double-open type that opens to both sides from the hinge center at both ends. The upper freezer compartment door 3a, the ice making compartment door 4a, the freezer compartment door 5a, and the vegetable compartment door 6a are constituted by drawer-type doors, and a drawer container in the storage chamber is pulled out together with the drawer door.

  FIG. 2 is a configuration diagram of the refrigerating chamber doors 2a and 2b and the rotary type squeeze member 11 which is an example of a squeeze member. FIG. 3 is an explanatory view of the structure of the rotary type squeeze member 11.

  Hereinafter, although the rotary type squeeze member 11 will be described in a state where it is provided in the refrigerator compartment door 2b, the same effect can be obtained even when a symmetric refrigerator with the same configuration is provided in the refrigerator compartment door 2a. The rotary type squeeze member 11 fills a gap between these two members that is generated when the refrigerator doors 2a and 2b are closed. As a result, the rotary squeeze member 11 suppresses cold air leakage in the refrigerator compartment 2.

  As shown in FIG. 3 (B), the rotary type squeeze member 11 has a heat insulating component 15 on the center side. The rotary squeeze member 11 includes a front member 12 provided on the front surface, a back member 13 provided on the back surface, and a top surface component 14 that fits with a guide member 21 provided at the edge of the opening that the refrigerator door 2 opens and closes. ing. The front member 12 has a magnetic metal so as to be attracted to a magnet 35 (for example, see FIG. 5B) of a gasket provided in the refrigerator compartment doors 2a and 2b. In order to suppress the condensation of the front member 12, a heater (not shown) is provided between the front member 12 and the heat insulating member 15 along the extending direction of the front member 12 (vertical direction in FIG. 3). Yes. As the heat insulating component 15, for example, styrofoam can be used.

The rotary type squeeze member 11 is provided in the refrigerator compartment door 2b.
The rotary type squeeze member 11 is rotated by guidance of the guide member 21 and the rail 14a during the opening / closing operation of the refrigerator compartment door 2b. When the refrigerator compartment door 2b is closed, the front member 12 faces in a direction perpendicular to the rotation center of the refrigerator compartment door 2b. However, when the refrigerator compartment door 2b is opened, the front member 12 is It rotates so as to face the rotation center of the refrigerator compartment door 2b. When the refrigerator compartment door 2b is closed, the refrigerator compartment door 2b is rotated so as to face a direction perpendicular to the rotation center of the refrigerator compartment door 2b.

  Therefore, the rotary squeeze member 11 can open the refrigerator compartment door 2b without interfering with the refrigerator compartment door 2a. Note that the rotary type squeeze member 11 is biased by a spring, and maintains the state of being rotated by the rail 14a and the guide member 21, that is, the state of being tilted inward when the refrigerator compartment door 2b is open.

  4A and 4B are configuration diagrams in which a door opening detection means is provided on the rotary squeeze member 11, FIG. 4A is an overall view of the rotary squeeze member 11, and FIG. 4B is a longitudinal sectional view. 5-7 is the figure which showed the door open state of the refrigerator compartment, each (A) is the state of the actual refrigerator 1, and each (B) is a simplified diagram explaining door open detection.

  The top surface member 14 includes a rail 14 a, a U-shaped support portion 14 c that supports an electronic substrate 34 to be described later, and an abutting portion 14 b that abuts the upper surface of the front member 12. The lower surface of the front member 12 is also abutted in the same manner, thereby fixing the front member 12. The front member 12 is not limited to butting, and may be fixed by various known methods such as locking and screw fixing. The top member 14 can be made of a resin material, for example.

  By providing the support portion 14c on the top surface member 14, the magnetic detection sensor 32 can be easily supported. An electronic board 34 on which a magnetic detection sensor 32 is mounted is disposed inside the rotary type squeeze member 11. One side of the electronic substrate 34 is supported by the support portion 14c. In addition, the front side of the rotary squeeze member 11 is covered with the front member 12. Since the front side of the rotary squeeze member 11, i.e., the front member 12 can be configured as a single member, the design of the rotary squeeze member 11 can be improved.

  A magnetic material such as metal is used for the portion of the front member 12 that overlaps the magnetic detection sensor 32 in front view. For this reason, the magnet 35 can be attracted to the front surface of the magnetic detection sensor 32. Therefore, when a magnet is brought close to the front surface of the magnetic detection sensor 32, the magnet can improve the adhesion with the rotary type squeeze member 11 when the refrigerator door 2 is closed, thereby suppressing cold air leakage.

  When the refrigerator compartment door 2 is closed, the magnet 35, the front member 14, and the magnetic detection sensor 32 are partially or entirely overlapped when the refrigerator main body 1 is viewed from the front. That is, there is at least one region where the magnet 35, the front member 14, and the magnetic detection sensor 32 all overlap in a front view.

  In addition, the cord of the electronic board 34 is arranged along a cord-like heater provided on the front member 12. Further, the magnetic detection sensor 32 is arranged at a position where a part or all of the magnets 35a provided on the gasket 36 of the refrigerator compartment door 2a face partly when the refrigerator compartment door 2a is closed. Thereby, the magnetic detection sensor 32 can detect the open / closed state of the refrigerator compartment door 2.

Next, a method for detecting opening and closing of the refrigerator compartment doors 2a and 2b will be described.
First, as shown in FIG. 5, when both the refrigerator compartment doors 2 are closed, the rotary type squeeze member 11 is in the state shown in FIG. 5 (B). The gasket magnet 35a of the right refrigerator compartment door 2a is magnetized in the front-rear direction (vertical direction in the figure). For this reason, the flux linkage to the magnetic detection sensor 32 by the gasket magnet 35a of the right refrigerator compartment door 2a is large. The magnetic detection sensor 32 detects that the amount of magnetic flux is large, that is, the refrigerator compartment doors 2a and 2b are closed.

  The rotating squeeze member 11 is attached with the refrigerator compartment door 2b side as a rotation center. The magnetic detection sensor 32 faces the gasket magnet 35a provided in the refrigerator compartment door 2a.

  On the other hand, as shown in FIG. 6, when the left side refrigerator compartment door 2b is open, the rotary type squeeze member 11 is guided by the guide member 21 and the rail shape 14a as shown in FIG. 6B. 2b falls and the distance between the magnetic detection sensor 32 and the gasket magnet 35a increases. For this reason, the interlinkage magnetic flux to the magnetic detection sensor 32 by the gasket magnet 35a of the right refrigerator compartment door 2a decreases.

  Moreover, as shown in FIG. 7, when the right side refrigerator compartment door 2a is open, the rotation squeeze member 11 faces the same direction as when the refrigerator compartment doors 2a, 2b are closed. Since the gasket magnet 35a is separated from the magnetic detection sensor 32, the flux linkage from the gasket magnet 35a of the right refrigerator compartment door 2a to the magnetic detection sensor 32 is reduced.

  As described above, the magnetic detection sensor 32 reduces the amount of linkage flux detected when the right or left refrigerator compartment door 2 is open.

  As described above, the magnetic detection sensor 32 detects a relatively large flux linkage only when both of the refrigerator compartment doors 2a and 2b are closed, and when one of the refrigerator compartment doors is open, the magnetic detection sensor. 32 detects relatively small flux linkage or does not sense flux linkage. That is, it is possible to detect that one or both of the two refrigerator compartment doors 2a and 2b are open and both are closed by using one magnetic detection sensor 32.

  Thus, by detecting the open / closed state of the refrigerator compartment door 2 through the difference in the amount of magnetic flux, it is possible to appropriately perform the cooling control, the control of the interior lamp, and the buzzer control of the half door warning.

  If it is desired to detect which of the refrigerator compartment doors 2a and 2b is open, as shown in FIG. 8, the refrigerator compartment door of the rotary type squeeze member 11 has a positional relationship facing when the refrigerator compartment door 2 is closed. What is necessary is just to arrange | position the magnet 35b to the another magnetic detection sensor 320 on the 2b side, and the refrigerator compartment door 2b. At this time, when both refrigerator compartment doors are closed, the magnetic flux linked to the magnetic detection sensors 32 and 320 is relatively large. When only the left refrigerator door 2b is opened, the magnetic flux linked to the magnetic detection sensor 32 is relatively small. At this time, since the magnetization direction of the magnet 35b faces the rotation center of the refrigerator compartment door 2b, the magnetic flux linked to the magnetic detection sensor 320 becomes relatively small. On the other hand, when only the right refrigerator compartment door 2a is opened, the magnetic flux linked to the magnetic detection sensor 320 is relatively small, and the magnetic flux linked to the magnetic detection sensor 320 is relatively large.

  Note that a temperature sensor may be mounted on the electronic substrate 34. Energy efficiency can be improved by detecting the temperature of the front member 12 by the temperature sensor and controlling the heater. Also, the assembly can be improved by combining the wiring for the heater and the substrate 34. At this time, since the front member 12 has a metal, heat conduction is relatively good. For this reason, the accuracy of the temperature detected by the temperature sensor is increased, and effective control becomes possible. Furthermore, since the electronic substrate 34 is supported by the support portion 14 c of the top surface member 14, the electronic substrate 34 is positioned on the upper end side of the rotary type squeeze member 11. For this reason, when the heater is disposed, the electronic substrate 34 does not get in the way.

  As described above, the rotary type squeeze member 11 has been described as an example in which the squeeze member between the gasket and the magnetic detection sensor 32 is made of a magnetic material. However, when the drawer type door is closed, the same structure is brought into contact with the drawer type door gasket. It can be applied to a drilling member. At this time, the limit member is an edge of the front opening of the refrigerator main body 1.
