JP 2001-174139 A

  By the way, in the refrigerator, the open range when the door is opened includes a self-closing region, a half-door region, and a door opening detection region in order from the side closer to the refrigerator body. The self-closing area is an area in which an automatic door closing function for automatically closing the door from a state slightly before the complete closing works when the door is closed from the open state. The half-door region is a region from the self-closing region to the next door opening detection region. The door opening detection area means that when the door is opened at a certain angle, the door switch detects that the door is open (ON), the interior lamp is turned on, and the door opening time exceeds a predetermined time of, for example, about 30 seconds. This is an area for reporting an alarm. Accordingly, the half-door region is a region between the self-closing region and the door opening detection region, and the automatic door closing action does not work and the door opening is not detected.

  When the above-described abnormal vibration occurs, if the door opening restricting device restricts the opening of the door in a so-called half-door region, the door is not completely closed, and the door opening is not detected and no alarm is notified. (In other words, the user is unaware of the door opening), and the door is left unattended for a long time without the user noticing, so that the cool air is discharged.

  In view of this, a refrigerator is provided that can prevent the door from being inadvertently opened largely during an abnormal vibration such as an earthquake and can prevent the door from being left open.

  The refrigerator of the embodiment includes a door that opens and closes the opening of the refrigerator main body, and in the open range of the door, from the side close to the refrigerator main body, a self-closing region in which an automatic closing action works, a half-door region, and a door A door opening detection area in which an alarm is notified by opening being detected for a predetermined time in order, provided in the refrigerator body, and vibration detecting means for detecting abnormal vibration of the refrigerator body; A door opening restricting device for restricting opening of the door from the refrigerator main body at a distance less than a half-door region in response to abnormal vibration detection of a vibration detecting means;

  Hereinafter, the refrigerator according to the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the refrigerator 1 according to the embodiment includes a refrigerator body 2. This refrigerator main body 2 has storage rooms, such as a refrigerator compartment and a freezer compartment, inside. The opening of this storage room (for example, a refrigerator room) is opened and closed by the door 3. A gasket 3 a is provided at the opening side of the door 3. The door 3 is pivotally supported by a hinge mechanism 4 (see FIG. 2) covered with a hinge cover 4a. The hinge mechanism 4 is provided at the upper and lower portions of one end of the door 3 (the right end in FIG. 2). In this case, only the upper hinge mechanism 4 is shown, but the lower hinge mechanism has the same configuration although there is a difference in the vertical direction. The upper hinge mechanism 4 will be described.

  As shown in FIG. 2, the hinge mechanism 4 includes a main body side hinge plate portion 5 attached via a mounting plate portion 5 b so as to protrude from the upper corner portion of the ceiling portion of the refrigerator main body 2, and one upper surface end of the door 3. The door side hinge board part 6 attached to the part is provided. The main body side hinge plate portion 5 is formed with a bearing hole 5a, and the door side hinge plate portion 6 has a shaft portion 6a protruding upward. This shaft portion 6a is rotatably inserted and fitted into the bearing hole 5a, so that the door 3 is provided on the refrigerator main body 2 so as to be rotatable (openable and closable).

  The hinge mechanism 4 is provided with an automatic door closing mechanism 7. The automatic door closing mechanism 7 includes a guide arm portion 8 provided integrally with the main body side hinge plate portion 5 and a pin portion 9 provided on the door side hinge plate portion 6. A guide portion 8a protrudes forward from the tip of the guide arm portion 8, and a substantially mountain-shaped cam portion 8b is formed on the inner edge of the guide portion 8a. The cam portion 8b has a front oblique side portion 8b1 and a rear oblique side portion 8b2. The pin portion 9 is present at a position in sliding contact with the cam portion 8b.

  When the door 3 is closed from the open state shown by the two-dot chain line in FIG. 2 (when it is rotated in the direction of arrow A), the pin portion 9 encounters the front oblique side portion 8b1 of the cam portion 8b and guide arm The front side hypotenuse 8b1 is overcome while the part 8 is deformed to expand. When the pin portion 9 reaches the rear oblique side portion 8b2, the pin portion 9 is urged by the rear oblique side portion 8b2 in the door closing direction (arrow A direction) by the restoring force of the guide arm portion 8. As a result, the door 3 is automatically closed. As shown in FIG. 3, the self-closing region (self-closing region in which the automatic door-closing function works) R <b> 1 in which the door 3 is automatically closed in this way is the gasket 3 a of the door 3 on the front surface of the refrigerator body 2 (front surface of the opening). ) It is shown in the region from the position (opening angle K0 (zero)) where the magnet contacts the 2a and the magnet inside the gasket 3a is attracted to the angle K1. Further, the area of angle K2 shown in FIG. 3 shows a half-door area R2 described later, and the area of angle K3 shows a door opening detection area R3 described later.

  Further, as shown in FIG. 1, a vibration sensor 10 as vibration detecting means is provided on the upper portion of the refrigerator main body 2. The vibration sensor 10 is composed of, for example, an acceleration sensor. In this case, the vibration sensor 10 can detect vertical acceleration, that is, vertical vibration. Note that the vibration detection means may not be an electrical sensor, but may be a mechanical vibration detection mechanism, which will be described later.

  As shown in FIG. 1, a door opening restricting device 11 is provided on the upper portion of the refrigerator body 2. As shown in FIGS. 4 to 7, the door opening restriction device 11 includes an electromagnetic solenoid 12, a pressing member 13, a cover member 14, a locking member 15, a return spring 16, a guide member 17, And a locked portion 18.

  The electromagnetic solenoid 12 is provided on the upper surface of the refrigerator body 2 via a unit plate 19. The electromagnetic solenoid 12 has a coil inside the main body 12a and a plunger 12b that moves forward by applying a one-way current to the coil and moves backward by applying a reverse current. The pressing member 13 is attached to the front end portion (the left end portion in the drawing) of the plunger 12b. The pressing member 13 has a downwardly inclined surface portion 13a at the lower portion, and the inclined surface portion 13a is inclined so as to descend from the front end (the left end in the drawing) toward the rear end.

  The cover member 14 has a left and right side wall portion and an upper wall portion, and is provided so as to cover the rear side of the pressing member 13 and the locking member 15 in front of the electromagnetic solenoid 12. As shown in FIG. 6, two (a total of four) guide members 17 are attached to the inner surfaces of the left and right side walls of the cover member 14 so as to be directed in the vertical direction.

  As shown in FIG. 6, the locking member 15 has two guided grooves 15 a extending in the vertical direction on the left and right side surfaces, and each guided groove 15 a is movable up and down with respect to each guide member 17. It is mated. Thus, the locking member 15 is provided so as to be movable up and down. An upward inclined surface portion 15 b is formed on the upper surface of the rear end portion of the locking member 15. The slope 15b is inclined upward from the rear end toward the front end. The slope 15b is slidably in contact with the slope 13a of the pressing member 13.

A locking portion 15 c is provided below the front end portion (tip portion) of the locking member 15. The locking portion 15c protrudes downward in a substantially mountain shape, and has an inclined portion 15c1 facing the rear side and an inclined portion 15c2 facing the front side. The locking member 15 receives upward biasing force from the return spring 16 and is in the upper movement limit position P1 when the plunger 12b is retracted (the state shown in FIG. 4).
The locked portion 18 is formed on the upper surface of the closed door 3 so as to be positioned below the locking portion 15c. The locked portion 18 has a concave shape, and an inner surface on the rear side is an inclined portion 18a.

As shown in FIG. 7, the locking portion 15c of the locking member 15 can lock the locked portion 18 when the door 3 is in the closed position (angle K0) (opening of the door 3 can be regulated). It is.
As shown in FIG. 1, an operation panel 20 is provided on the front surface of the door 3. The operation panel 20 includes an operation input unit 21 (see FIG. 8) made up of, for example, a touch switch, and an abnormality notification means. A display 22 (see FIG. 8) is provided. The operation input unit 21 includes a manual restriction release switch, a manual restriction switch, and the like.

  The electrical configuration will be described with reference to FIG. FIG. 8 shows an electrical configuration related to door opening restriction. The control device 23 is mainly composed of a microcomputer. On the input side of the control device 23, the vibration sensor 10, the operation input unit 21, a door switch 24 as a door opening detection unit and a door closing detection unit are connected. The output side of the control device 23 is connected to the electromagnetic solenoid 12, the display 22, the buzzer 25, the interior lamp 26, and a speaker 27 as abnormality notification means. The buzzer 25 and the speaker 27 are provided in the hinge cover 4a.

The door switch 24 is provided at an opening in the refrigerator main body 2 so that the opening and closing of the door 3 can be detected. As shown in FIG. 3, the door switch 24 detects that the door 3 is opened (switched on) when the door 3 is turned from the closed state to the opening direction by an angle Kα and is turned from the opened state to the closing direction. When the angle Kα is reached, blockage of the door 3 (not complete blockage) is detected (switched off).
In this case, the angle Kα is larger than the angle K1, and an angle region equal to or larger than the angle Kα is set as a door opening detection region R3. A region between the angles K1 and Kα is a half-door region R2.

That is, the self-closing region R1 has an angle of 0 ° (angle K0) or more and an angle K1 or less, the half-door region R2 has an angle greater than K1 to less than an angle Kα, and the door opening detection region R3 has an angle of Kα.
The control device 23 performs a door opening detection control operation shown in FIG. 9 based on on / off of the door switch 24. When the user opens the door 3, the door switch 24 is turned on at the position of the angle K3. When the control device 23 determines that the door switch 24 is turned on (“YES” in step S1), the interior lamp 26 is energized and lit (step S2). Before a predetermined time (for example, any one of 30 seconds to 1 minute) has elapsed since the door switch 24 was turned on ("NO" in step S3), the door switch 24 was turned off (the door 3 was closed and passed through the angle Kα). When this is done (“YES” in step S4), the internal lamp 26 is turned off (step S5). When the predetermined time elapses with the door switch 24 turned on, the buzzer 25 is informed (alarmed) (step S6). Thereafter, when the door switch 24 is turned off ("YES" in step S7), the internal lamp 26 is turned off and the notification operation of the buzzer 25 is stopped (step S8).

As can be seen from the above, when the door 3 is in the door opening detection region R3, an alarm is notified to notify the user of the door opening after a predetermined time has elapsed.
Further, the control device 23 performs the abnormal vibration detection control operation shown in FIG. 10 based on the detection operation of the vibration sensor 10. When the vibration sensor 10 detects abnormal vibration during an earthquake or the like, the detection input is given to the control device 23. The control device 23 determines that abnormal vibration has been detected (detection input has been made) (step T1), notifies the speaker 27 that an abnormality such as an earthquake has occurred by voice, and uses the display 22 to perform the same operation. The occurrence of abnormality is displayed (notified) (step T2). Then, the electromagnetic solenoid 12 of the door opening regulating device 11 is controlled so that the plunger 12b advances in the direction of arrow B in FIG. 4 (one-way current is applied to the coil) (step T3).

  As the plunger 12b advances in the arrow B direction, the pressing member 13 moves in the arrow B direction, and the inclined surface portion 15b moving in the same direction presses the inclined surface portion 15b of the locking member 15 downward. As a result, as shown in FIG. 5, the locking member 15 moves downward (locking direction), and the locking portion 15 c enters the locked portion 18 of the door 3 to move the locked portion 18. Lock. That is, the opening of the door 3 is restricted.

In this case, as shown in FIGS. 5 and 7, the locking member 15 regulates the opening of the door 3 in a state less than the half-door region R2, that is, in this case, an angle of 0 ° (angle K0). Further, in the state of FIG. 5, the plunger 12b is not yet at the movement limit position, and the locking member 15 has not reached the lower limit position Pe. Therefore, the locking member 15 is further urged to move downward (the electromagnetic solenoid 12 is in a unidirectional current application state). For this reason, the inclined portion 15c1 of the locking portion 15c further biases the locked portion 18 of the door 3 in the door closing direction (self-closing direction). That is, the door opening restricting device 11 further biases the door 3 in the closing direction from the closed state. When the manual restriction release switch in the operation input unit 21 is operated (“YES” in step T4), the control device 23 applies a reverse current to the coil so that the plunger 12b moves back the electromagnetic solenoid 12 ( Step T5) Then, since the pressing member 13 moves backward, the locking member 15 rises and returns to the original position (regulation is released).
In addition to the input from the vibration sensor 10, the control device 23 controls the electromagnetic solenoid 12 so that its plunger 12b is advanced (step T3) when the manual restriction switch is operated (“YES” in step T6). ).

In the present embodiment described above, the refrigerator main body 2 is provided with the vibration sensor 10 as vibration detection means, and the door opening restriction device 11 for restricting the opening of the door 3 in response to the abnormal vibration detection of the vibration sensor 10 is provided. Therefore, it can regulate so that the door 3 may not open carelessly at the time of abnormal vibrations, such as an earthquake. Furthermore, according to the present embodiment, the door 3 is regulated at a distance less than the half door region R2 from the refrigerator body 2 in this case, a distance shorter than the outermost side of the self-closing region R1 (within the self-closing region R1). 3 is closed by the automatic door closing mechanism 7, and the door 3 can be prevented from being left open.
In addition, according to the present embodiment, the door opening restriction device 11 is configured to further bias the door 3 in the closing direction from the closed state, so that the door 3 with respect to the refrigerator main body 2 is blocked even when abnormal vibration continues. I can leave it to you.

  Further, in the present embodiment, the door opening restricting device 11 is provided on the door 3 side with a locking member 15 provided in the refrigerator main body 2 in response to abnormal vibration detection of the vibration sensor 10 and having a locking portion 15c at the tip. And a latched portion 18 that is latched to the latching portion 15c and restricts the opening of the door 3 by the latching, and the latching portion 15c and the latched portion 18 are respectively connected to the latching portion 15c. Inclined portions 15c1 and 18a for urging the door 3 from the closed state further in the closing direction are provided. According to this, opening of the door 3 when abnormal vibration occurs can be restricted with a simple configuration, and the door 3 can be further urged in the closing direction from the closed state. Note that it is sufficient that at least one of the locking portion 15c and the locked portion 18 for urging the door 3 from the closed state further in the closing direction is provided.

  By the way, as shown in FIG. 11, the case where the door opening control apparatus 11 act | operates in the state which the door 3 opened is assumed. In this case, when the user tries to close the door 3, the door 3 may not be closed by the locking member 15 moving to the lower limit position Pe. If it cannot be closed, cold air will leak. In this case, if the manual restriction release switch is operated in order to return the door opening restriction device 11, the locking member 15 is raised, but this takes time. In the first embodiment, the electromagnetic solenoid 12 is disconnected at the lower limit position Pe, and the plunger 12b can move when the electromagnetic solenoid 12 is disconnected.

  In this regard, in the present embodiment, the locking member 15 is formed with the inclined portion 15c2 to allow the door 3 to be closed. That is, when the door 3 is rotated in the closing direction (arrow C direction) from the state of FIG. 11, the door 3 comes into contact with the inclined portion 15 c 2 and moves and urges the locking member 15 upward. This allows the door 3 to be closed. According to this, even if the door opening restricting device 11 operates in a state where the door 3 is opened, if the door 3 is simply closed, it can be instantaneously closed.

  In the present embodiment, the display 22 and the speaker 27 are provided as abnormality notification means, and when the vibration sensor 10 detects abnormal vibration, the display 22 and the speaker 27 are caused to perform an abnormality notification operation. . According to this, it is possible to notify the user that abnormal vibration has occurred and that the opening of the door 3 has been restricted. Note that any one of the display 22 and the speaker 27 may be used as the abnormality notification means. Moreover, it is good also as a structure which utilizes the buzzer 25 as an abnormality notification means.

Further, according to the present embodiment, since the vibration sensor 10 as the vibration detecting means can detect the vibration in the vertical direction, the first vibration at the time of the occurrence of the earthquake can be detected, and the occurrence of the earthquake Sometimes the door opening restricting device 11 can be operated quickly.
The vibration detection means may be a mechanical vibration detection mechanism that detects abnormal vibration using a weight or the like and operates in response to the abnormal vibration detection, instead of the vibration sensor 10 that electrically detects abnormal vibration. . In this case, the door opening restricting device may not be provided with an electric drive source such as an electromagnetic solenoid, and may operate the locking member by utilizing (responsively) the mechanical operating force of the vibration detecting mechanism. . Further, the locking member may not be a vertical movement method, and may be a rotation type, for example.

  In the present embodiment, the operation input unit 21 that can be operated by the user is provided, and the door opening restriction device 11 can be operated based on the operation of the operation input unit 21 (operation of a manual restriction switch). According to this, it is possible to restrict the opening of the door 3 on the occasion desired by the user other than when the abnormal vibration occurs in the door opening restriction device 11, which is convenient.

  12 and 13 show a second embodiment. In the second embodiment, the locking member 15 is provided on the inclined portion 15c1 of the locking portion 15c when the locking member 15 is in the lower limit position Pe (in this second embodiment, the electromagnetic solenoid 12 is continuously energized at this position Pe). On the other hand, as shown in FIG. 13, the position of the locked portion 18 (the position of the inclined portion 18a) in the state where the door 3 is closed is set so as to be relatively separated from the distance g. This distance g is a distance shorter than the outermost side of the self-closing region R1, as shown in FIG.

  Accordingly, the door 3 is restricted from being opened with the distance g shown in FIG. And in this state, since the door 3 exists in the short distance (within self-closing area | region R1) from the outermost side of self-closing area | region R1, the door 3 is obstruct | occluded to the obstruction | occlusion position of FIG. In the second embodiment, since the door 3 can be self-closed if the distance g is an arbitrary distance within the self-closing region R1, the positional relationship between the locking portion 15c and the locked portion 18 is satisfied. The degree of freedom can be increased, and the degree of freedom in design increases.

  Next, FIGS. 14 and 15 show a third embodiment. In the third embodiment, the door opening restriction device 11 restricts the opening of the door 3 from the refrigerator main body 2 by a distance ga within the door opening detection region R3. It is configured to do. In this case, among the distances in the door opening detection region R3, the door opening angle is set as small as possible. For example, the distance from the open end inside the door to the opening of a storage room such as a refrigerator can be 8.8 cm or less. Then, a 2-liter heavy plastic bottle (in the case of a substantially rectangular plastic bottle, approximately 10.5 cm in the lateral width, 8.8 cm in the front-rear width, 31 cm in height) will not fall from the gap of the distance ga. You can avoid being injured by dropping the heaviest item in the house. Moreover, the same effect can be obtained by setting the distance ga to be less than the length of the depth dimension of the door pocket (portion for storing drinking water or the like) of the door of the storage chamber.

In the third embodiment, when the abnormal vibration occurs in the closed state shown in FIG. 14, the locking member 15 is lowered as described above. In this case, even if the door 3 is opened due to abnormal vibration, the opening of the door 3 is restricted by the distance ga by the door opening restriction device 11 as shown in FIG.
According to the third embodiment, the opening of the door 3 is restricted from the refrigerator main body 2 by the distance ga within the door opening detection region R3, and at this distance ga, the interior lamp 26 is turned on by the control device 23. Since the alarm notification control is performed for the buzzer 25 after a predetermined time, the user becomes aware that the door 3 has been opened, and thus it is possible to prevent the door 3 from being left open.

Further, the lighting control of the interior lamp 26 when the door opening is regulated may be blinked, for example, so that the lighting control may be different from that when the door is not regulated.
In the case of the third embodiment, the self-closing region by the automatic door closing mechanism 7 may or may not exist in the opening range of the door 3 (the automatic door closing mechanism 7 may or may not be present). In FIG. 3, the area by the angle α in FIG. 3 is the half door area R2.

  Next, FIG. 16 shows a fourth embodiment. In this 4th Embodiment, the door 3 is comprised by the kannon type door structure from the right door 3A and the left door 3B, The single opening part of the refrigerator main body 2 is comprised by this right door 3A and the left door 3B. Open and close. Then, locked portions 8A and 8B are formed at adjacent ends on the upper surfaces of the right door 3A and the left door 3B, and the locking portions 15c of the locking member 15 of the door opening restriction device 11 are both locked portions 8A. , 8B can be locked. Thereby, the door opening restricting device 11 can simultaneously restrict the opening of the plurality of doors 3A and 3B.

Note that the door opening restriction device 11 may not operate when the vibration sensor 10 detects an abnormality in a state where the door 3 is opened by the user.
If abnormal vibration is detected, the refrigerator may be turned off until the vibration is reduced. When a refrigeration cycle using a flammable refrigerant is used, the refrigerant piping is broken due to abnormal vibration and ignition due to high voltage is concerned, but the concern is solved by turning off the refrigerator. Further, when the vibration is continuously detected for a predetermined time or when the vibration is detected a plurality of times, the power is turned off to prevent the power from being turned off due to the abnormal vibration detection.

  Moreover, you may mount the storage battery which is an auxiliary power supply in this refrigerator. When vibration (abnormal vibration) is detected, switching means for switching to an auxiliary power source may be provided. When the door is open in a state where the door opening is restricted, the interior lamp may be lit by an auxiliary power source. In this way, the interior lamp can function as a spare lamp for the room when an earthquake occurs at midnight.

In addition, when the internal lamp is used as a room spare lamp by the auxiliary power source, it is preferable to release the door opening restriction and open the door. In that case, since an alarm is also sounding at the same time, an operation unit for canceling the alarm may be provided in the operation input unit so that only the lighting is performed.
Further, the display method of the display 22 on the front surface of the door may be changed when abnormal vibration is detected to increase the luminous intensity. Moreover, you may provide a manual operation part about the inside lamp | ramp being made into the said spare lamp with a backup power source. Moreover, you may give the effect as a preliminary | backup light of a dark room because the operation part which lights most or all among several LED with which the refrigerator was equipped has the function to adjust a brightness | luminance.
