Description

  The present invention relates to a refrigerator.

  In recent years, since the capacity of refrigerators has increased and the storage rooms have become larger, the doors that inevitably cover the storage rooms have also become larger. The refrigerator door is provided with a packing with magnets around the inside, and this packing is in close contact with the metal frame on the front of the main unit housing, so that it can be stored when the door is closed. The space is sealed. For this reason, in order to open the open / close door, the close contact between the packing and the main body housing must be released. Therefore, in order to open the open / close door that covers the large storage chamber, a large force is required to release the close contact of the packing having a large contact area.

  Therefore, the mainstream refrigerator is a so-called double door opening / closing door (French door) in which a refrigerator compartment having the largest volume is arranged at the uppermost part of the storage room, and both front sides thereof are pivotally supported by a rotating shaft. Covering structure. According to the open / close door with this double door structure, since the close contact of the packing is dispersed by the two open / close doors, the respective open / close doors can be opened easily. In addition, when opening and closing food, one open / close door can be opened without opening the entire large refrigerator compartment, which is advantageous from the viewpoint of reducing cold air leakage.

  On the other hand, the door with this double door structure is provided with a rotating partition on the free end side of one of the doors in order to prevent cold air leakage between the pair of doors. When the rotating partition is closed, the rotating partition is unfolded to close a space between the pair of opening / closing doors, and when opened, the rotating partition is folded to the free end side. For this reason, in the opening / closing structure provided with the rotating partition, it is possible to freely open and close the other opening / closing door as well as opening / closing one opening / closing door provided with the rotating partition while reducing cold air leakage in the storage chamber.

  In addition, the open / close door with the double door structure is configured to be openable / closable via a handle provided on a lower end portion or a free end door surface of each open / close door.

  And in patent document 1, the link mechanism operates so that when one door is opened and closed, the fulcrum moves back and forth with respect to the double doors that are opened and closed simultaneously with one door. The structure which opens and closes the other door is also disclosed.

  Hereinafter, a refrigerator according to an embodiment of the present invention will be specifically described with reference to FIGS. In addition, the same site | part, direction, etc. are shown with the same code | symbol, and the overlapping description is abbreviate | omitted.

  First, a refrigerator according to this embodiment will be described in detail with reference to FIGS. FIG. 1 is a schematic configuration diagram of a refrigerator according to an embodiment. FIG. 2 is a longitudinal sectional view in the AA direction of the refrigerator according to the embodiment shown in FIG. FIG. 3 is an assembly view of the opening mechanism 8 of the open / close door according to the embodiment shown in FIG. FIG. 4 is a partial external view of the opening mechanism 8 of one of the doors according to the embodiment shown in FIG. FIG. 5 is a partial external view of the opening mechanism 8 of the other opening / closing door according to the embodiment shown in FIG.

  In FIG. 1, the refrigerator 1 is a large-sized refrigerator having a plurality of storage chambers partitioned by a plurality of partition walls and having an internal volume of 500 L or more. In this embodiment, the refrigerator compartment 2 is provided at the top, the ice making compartment 4 and the second freezer compartment 3 arranged on the left and right below, the freezer compartment 5 below, and the vegetable compartment 6 at the bottom. The storage rooms having different temperature zones are divided by heat insulating partition walls. The middle freezer compartment 5 is divided from the ice making compartment 4 and the second freezer compartment 3 by a partition wall without a heat insulating material. Each storage chamber is an open / close door filled with a heat insulating material, and the front surface of the storage chamber is covered to form a closed storage chamber. By opening the open / close door, food can be taken in and out. Door detection (not shown) is provided on both side portions of the main body casing 11 to detect that the open / close doors 2L and 2R are closed.

  That is, in this embodiment, the refrigerator compartment 2 capable of opening and closing the pair of doors 2L and 2R with double doors is arranged at the top, and the drawer-type doors 3a and 4a are provided on the left and right sides of the refrigerator compartment 2 respectively. 2 The freezing room 3 and the ice making room 4 are arranged, the first freezing room 5 in which the drawer type opening / closing door 5a is arranged is arranged in the lower stage, and the vegetable room 6 in which the drawer type opening / closing door 6a is arranged in the lowermost part. It is arranged.

  And one of the big characteristics of the refrigerator 1 which concerns on this Example is with the opening operation | movement of one of a pair of opening-and-closing doors 2L and 2R. It is in the point provided with the opening mechanism part 8 which can select whether the doors 2L and 2R are opened simultaneously.

  That is, the open / close doors 2L and 2R according to this embodiment are opposed to each other around the rotation shaft 31 provided on the fixed end 10a side on the hinge mechanism 10 side through the hinge mechanisms 10 provided on both sides of the main body casing 11. It is possible to open the free end 10b side (the opposite shaft support side). That is, the open / close doors 2L and 2R of this embodiment include a so-called French door that can be opened by moving the free end 10b on the center side around the fixed ends 10a on both sides of the refrigerator 1. ing. Each of the open / close doors 2L and 2R is provided with a packing 16 around the inner wall 18 of the door, and is in close contact with the main body casing 2 or the rotary partition 25 (see FIGS. 8 to 11) in a state in which the packing 16 is closed. By adsorbing with the magnet contained in 16, the structure in which the cool air in the refrigerator compartment 2 does not leak.

  Further, on the free end 10b side of the pair of opening / closing doors 2L, 2R, a rotary partition 25 is provided along the gap to close the space between the two opening / closing doors 2L, 2R. In this embodiment, a rotary partition 25 (see FIGS. 8 to 11) is provided on the other door 2L on the left side. When the rotary partition 25 is closed, the rotary partition 25 is engaged with the main body casing 11 to close the gap between the two open / close doors 2L and 2R, and in the open state, the rotary partition 25 is on the free end 10b side of the other open / close door 2R. Folded to the side and stored.

  Generally, in such a double door opening / closing door, the opening / closing operation can be performed via the handle portions 12L, 12R provided in the respective opening / closing doors. In this embodiment, the recessed doors 12L and 12R are formed at the lower ends of the open / close doors 2L and 2R on the free end 10b side, and the doors 2L and 12R are pulled by putting the hands on the handles 12L and 12R and pulling them forward. 2R can be opened. Therefore, in order to open the pair of opening / closing doors 2L, 2R at a time, the user needs to open the doors 2L, 2R by hooking their hands on the handle portions 12L, 12R. At this time, since each of the open / close doors 2L and 2R has a magnet built in the packing 16 in close contact with the metallic main body housing 2, in order to open the open / close doors 2L and 2R, the two close-contacts are required. A large force is required to release. In addition, if the two handle portions 12L and 12R are operated simultaneously, the user's feet are aligned, so the opening operation becomes unstable, and more force is required. Of course, it can be opened one by one, but it takes twice.

  Therefore, in this embodiment, the operating member 13 is provided on the front side of one of the open / close doors 2R, and the connecting portion 14 projecting to the open / close door 2L side with the operation of the operating member 13 is provided on the free end 10b side (anti-axial support). And an opening mechanism portion 8 including an engaging portion 15 that engages with the connecting portion 14 on the free end 10b side of the other opening / closing door 2L. In this structure, if the operating member 13 is operated, the connecting portion 14 engages with the engaging portion 15, so that the operating member 13 is operated and the hand-held portion 12R of one of the open / close doors 2R is put on the front side. The other door 2L can be opened with the opening operation of one door 2R. Therefore, according to this embodiment, since the two opening operations are performed by the operation of one hand, it is possible to reduce the labor for the user to open both doors at the same time and to take an unreasonable posture accompanying the opening operation. That can be reduced.

  FIG. 3 shows an assembly view of the opening mechanism of the door. The handle portion 12R is provided as a concave portion on the free end 10b side (counter shaft support side) of the door bottom surface member 9 of the open / close door 2R.

  The operation member 13 has a concave portion 13a and a flange portion 7 provided at a lower end portion of the concave portion 13a. And the operation member 13 is provided so that the recessed part 13a may be accommodated in the recessed part of the handle part 12R. That is, the concave portion 13a is located in the handle portion 12R, and the operation member 13 is appropriately positioned by the upper end of the flange portion 7 being in contact with the lower end of the handle portion 12R.

  The operating member 13 has a recessed portion 13a incorporated in the handle portion 12R so as to be slidable left and right. In this configuration, when the operating member 13 is slid in the direction of the free end 10b, the connected connecting portion 14 protrudes from the end surface (the opposite shaft side surface) of the right opening / closing door 2R (FIG. 4A). To (b) state). At this time, the flange portion 7 of the operation member 13 moves along the opening edge of the door bottom surface member 9 that forms the handle portion 12R.

  Accordingly, when the operator inserts a hand into the handle portion 12R, the hand is simultaneously positioned in the recess 13a of the operation member 13, so that the operability of the operation member 13 is improved. Moreover, it can be visually observed that the operation member 13 has moved, and a reliable operation can be realized.

  Next, an elastic body 23 (coil spring as an example) is provided on the shaft support side (the end opposite to the end where the connecting portion 14 is provided) of the open / close door 2 </ b> R in the operation member 13. The elastic body 23 acts on the operating member 13 so as to be pulled toward the shaft support side of the opening / closing door 2R. That is, in a state where the operation member 13 is not operated, the connecting portion 14 does not protrude from the end surface (the opposite shaft side surface) of the open / close door 2R.

  Reference numeral 17 denotes a protective cover that shields the operating member 13 and the connecting portion 14 constituting the opening mechanism portion 8.

  Further, the concave portion 13a of the operation member 13 has a box shape so as to be disposed in the handle portion 12 formed by the concave portion. Therefore, by forming the ridge line of the recess 13a in an arc shape, the structure is excellent in cleanability. Of course, the operation member 13 and the connecting portion 14 may be an integral part.

  Next, the left door 2L will be described with reference to FIG. The surface on the free end 10b side (anti-axis supporting side surface) of the opening / closing door 2L faces the anti-axis supporting side surface of the right opening / closing door 2R when the opening / closing doors 2L, 2R are closed, and opposes the connecting portion 14. An engaging portion 15 that is a concave portion is provided at the position.

  In FIG. 2, the heat insulating material 20 is, for example, urethane foam. After being injected in a liquid state into each of the open / close doors 2L and 2R, it is foamed by a chemical reaction and fills the inside of the open / close doors 2L and 2R. Manufactured. Therefore, by providing the door bottom member 9 as a partition wall, a region filled with the heat insulating material 20 can be partitioned, and a space for the opening mechanism portion 8 including the operation member 13 and the connecting portion 14 can be secured. .

  Next, a configuration for opening the left and right open / close doors 2L and 2R in conjunction with each other will be further described with reference to FIGS. 6A is a diagram showing the state of FIG. 4A, FIG. 6A is a diagram seen from the bottom surface side, and FIG. 6B is a schematic sectional view seen from the side surface. 7A and 7B are diagrams showing the state of FIG. 4B, in which FIG. 7A is a view seen from the bottom side, and FIG. 7B is a schematic cross-sectional view seen from the side. For convenience of explanation, the protective cover 17 is not shown in FIGS. 6 (a) and 7 (a).

  First, in FIG. 6, the operation member 13 is held by the door bottom surface member 9 and the protective cover 17, and is configured to be movable in the horizontal direction (left and right direction in the drawing). In this state, the operation member 13 is pulled toward the fixed end 10a by the elastic body 23 (as an example, a spring). Thereby, the front-end | tip of the connection part 14 is settled in one opening / closing door 2R. For this reason, if one hand is inserted into the handle portion 12R and pulled toward the front (upward in the drawing), only one of the open / close doors 2R can be opened.

  On the other hand, when the other opening / closing door 2L is also opened, as shown in FIG. 7, when the one hand inserted into the handle 12R is pressed against the free end 10b side (the opposite shaft side surface), the operation member 13 is moved toward the free end 10b side. Moving. Along with this movement, the connecting portion 14 moves to the free end 10b side, the tip of the connecting portion 14 protrudes from the end surface of the one opening / closing door 2R, and the other opening / closing door 2L facing the free end 10b side (reverse axis) It is inserted into the engaging portion 15 provided on the support side surface. Here, a gap Gap is provided between the connecting portion 14 and the engaging portion 15 provided in the left opening / closing door 2L.

  Next, the operation of opening the doors 2L and 2R on both sides with the above configuration will be described with reference to FIGS. 8 to 11 are views of a series of operations when the left and right open / close doors 2L and 2R are opened in conjunction with each other as viewed from the bottom.

  One of the major features of this embodiment is that the other opening / closing door 2R is opened with a time difference in accordance with the opening operation of one opening / closing door 2R.

  The two opening / closing doors 2L, 2R are in close contact with the packings 16L, 16R and the main body housing 11, respectively. If the two opening / closing doors 2L, 2R are to be opened at the same time, the two packings 16 are simultaneously attached to the main body. It is necessary to apply a force for releasing magnetization from the housing 11 (a force that opens larger than the magnetization distance). Therefore, compared with the case where only one of the open / close doors is opened, the force required for opening is required approximately twice. Therefore, if the two packings 16L and 16R are not brought into close contact with each other but separated from the main body housing 11 with a time lag, the force required to open the opening and closing doors 2L and 2R can be reduced and opened easily. it can.

  When the operator pulls and opens the right opening / closing door 2R forward (upper side in the figure) in the state of FIG. 7, as shown in FIG. 8, the magnets embedded in the packing 16 </ b> R provided on the right opening / closing door 2 </ b> R are After being separated from the refrigerator 1 or the rotary partition 25, the connecting portion 14 contacts the open contact portion 24 of the engaging portion 15. The force required for the opening operation so far is equivalent to the opening force when opening only the right opening / closing door 2R alone.

  Here, it is desirable that the gap has a dimension (a distance larger than the magnetizing distance) that can surely release the magnetization of the magnet contained in the packing 16R.

  When the operator further opens the right open / close door 2R from the state of FIG. 8, a force is applied to open the left open / close door 2L via the open contact portion 24, as shown in FIG. And the main body housing 11 are released from close contact with each other. Further, the rotary partition 25 rotates to open the left open / close door 2L. At this time, since the right opening / closing door 2R is already opened and can be opened with a very light force, the opening force is not particularly increased compared to when only the left opening / closing door 2L is opened. Thereby, even when both the left and right open / close doors 2L and 2R are opened in conjunction with each other at a time, the door can be opened with the same force as when only one door is opened. That is, the left and right open / close doors 2L and 2R can be simultaneously opened by one operation.

  When the left and right open / close doors 2L and 2R are opened, the end surfaces and the end surfaces facing each other (respectively pivoting side surfaces of the open / close doors 2L and 2R) gradually increase in distance. Assuming that the state shown in FIG. 10 is a state immediately before the doors 2L and 2R are separated from each other, when the right door 2R is further pulled forward from the state of FIG. 10, as shown in FIG. 10 to FIG. The outer periphery of the connecting portion 14 is no longer in contact with the concave portion of the engaging portion 15 and is separated. That is, the right open / close door 2R is kept open while the operator holds the handle 12R. On the other hand, the left opening / closing door 2L has a limit angle at which the angle θ shown in FIG. 10 can be reliably opened. Next, the relationship between the opening limit angle θ and the angle at which the closer described below operates will be described.

  2. Description of the Related Art Conventionally, an open / close door of a refrigerator employs a construction called a closer that prevents a half door by energizing the door in the direction in which the door is closed when the door is completely closed.

  The configuration and operation of an example of the closer mechanism will be described with reference to FIGS. FIGS. 12 to 14 show the movement of the closer and the force generated by the closer when the opening / closing door 2R is gradually closed.

  Since this closer is generally provided at the lower end of the opening / closing door 2R, FIGS. 12 to 14 schematically show the lower surface of the opening / closing door 2R. The left opening / closing door 2L has the same configuration. A fixed closer receiving metal fitting 46 is attached to the main body casing 11, and a cam portion 46 c formed in a smooth curved surface shape is provided in a part thereof. The open / close door 2R is provided with a closer elastic body 47 having a deformed portion 47a formed of a material having elasticity such as resin.

  As shown in FIG. 12, when the open / close door 2R rotates counterclockwise CCW and is closed to the angle φ1, the tip 47a of the closer elastic body 47 comes into contact with the cam portion 46c of the closer fitting 46, and the closer elastic body The tip 47a portion of 47 bends in response to the reaction force in the direction of arrow Fa. This force acts in the clockwise CW direction with respect to the rotary hinge 10a of the door, that is, in the direction to open the opening / closing door 2R. Therefore, when viewed from the user, the closing opening / closing door 2R becomes heavy from the middle. Further, the opening / closing door 2R is closed and the opening angle becomes φ2 as shown in FIG. 13, and the contact point between the closer elastic body 47 and the closer fitting 46 is on the same line as the rotary hinge 10a of the opening / closing door 2R, and becomes a neutral point. . Since the force Fb between the closer elastic body 47 and the closer fitting 46 is directed toward the rotation fulcrum, the moment is 0, and the opening / closing door 2R is balanced and cannot receive any opening / closing force. Therefore, there is a possibility of becoming a half door at this position. Since the closer elastic body 47 is bent and elastic energy is accumulated until reaching the neutral point, the open / close door 2R is not closed after the neutral point, and when the state shown in FIG. A force in the direction of arrow Fc is applied from the cam portion 46c to the closer elastic body 47. Since this force is a moment in the direction of closing the door 2R (counterclockwise CCW in FIG. 18) with respect to the rotary hinge 10a of the door 2R, the door 2R is closed by this force.

  Here, the relationship between the angle θ at which the left opening / closing door 2L is reliably opened and the angle φ2 at which the closer is the neutral point is desirably set so that φ2 <θ. Conversely, if φ2> θ, the left open / close door 2L once opened to the state of FIG. 14 is closed again by the closer.

  Furthermore, although not shown, if the angle φ3 at which the rotary partition 25 releases the locking relationship with the main body housing 11 and the relationship between the angle φ2 at which the closer operates and the angle φ3 is φ2 <φ3, then φ3 <θ. Needless to say, it must be set to be.

  In the above embodiment, the opening mechanism 8 is provided on the right door 2R. However, when the opening mechanism 8 is provided on the left door 2L and the operation member 13 is pressed, the right door is opened. The left and right structure may be reversed so that 2R opens in conjunction.

  Further, the pair of opening / closing doors may be formed such that one of the opening / closing doors has a larger width than the other, and the one opening / closing door is an opening / closing door having a large width.

  According to the above configuration, one or both of a pair of opening and closing doors can be selected and opened with a simple force, and when only one of the doors is to be opened, only one of the doors can be opened. Since both doors can be opened at the same time when the user wants to open the door, for example, even when one hand is holding and closing the door, the door can be opened easily and an easy-to-use refrigerator can be provided.
