When the vegetable compartment partition 74 is installed, the front storage space 6b1 is divided in front of the vegetable compartment partition 74 of the lower storage container 6b, and the rear storage space 6b2 is divided in rear of the vegetable compartment partition 74. When 74 is removed, the lower storage container 6b is configured as one storage space as a whole.

  Since the vegetable compartment partition 74 is arranged so as to be set on the higher surface of the step 60 provided on the bottom surface of the lower storage container 6b, the vegetable compartment partition 74 is stored in the upper stage from the higher surface of the step 60. Since it is only the height to the bottom face of the container 6c, the overall height of the vegetable compartment partition 74 can be suppressed and the size can be reduced, which is preferable.

  The vegetable compartment partition 74 is arranged close to the front side of the upper storage container 6c, and a latch for locking the vegetable compartment partition 74 and the upper storage container 6c via the latch means 80 at the upper end of the vegetable compartment partition 74. A receptacle 75 is provided, details of which will be described later.

Next, the structure of the vegetable compartment partition 74 is demonstrated using FIGS. 11-15.
FIG. 11 is a perspective view of the vegetable compartment partition 74 as viewed obliquely from the front, and is illustrated as an abbreviated view in which the left and right longitudinal directions are partially shortened. Furthermore, the partition guide 76 provided in the lower storage container 6b for attaching and detaching the vegetable compartment partition 74 is shown as a shape in which only that portion is taken out for explanation, and the vegetable compartment partition 74 and the partition guide 76 are It is the disassembled perspective view which shows a positional relationship.
FIG. 12 is a cross section FF in FIG. 11 and shows a cross sectional structure of the vegetable compartment partition 74.
FIG. 13 is a perspective view of the vegetable compartment partition 74 as viewed obliquely from the rear, and is illustrated as an abbreviated view in which the left and right longitudinal directions are partially shortened as in FIG. Furthermore, an exploded perspective view partially illustrating the configuration of the lower storage container 6b and the partition guide 76 is shown.
FIG. 14 is a plan view showing the arrangement of the vegetable compartment partition 74 and the lower storage container 6b.
15 is a cross-sectional view taken along the line GG in FIG. 13 showing the relationship between the vegetable compartment partition 74 and the lower storage container 6b.
As shown in FIGS. 11 to 13, the vegetable compartment partition 74 has a configuration in which a resin partition frame 74 b is integrally combined around a quadrilateral glass plate 74 a as an example. Since the glass plate 74a is transparent, when the vegetable compartment 6 is opened, the food stored in the lower storage container 6b can be observed through the vegetable compartment partition 74, and the amount and state of the food can be confirmed. It is preferable because it is easy.

  A receiving groove 74c, which is a concave portion, is provided along the lower portion of the vegetable compartment partition 74, and a bottom convex portion 77, which is an upward projection, is provided at a position corresponding to the receiving groove 74c of the lower storage container 6b. The bottom protrusion 77 and the receiving groove 74c have an effect of positioning when the vegetable compartment partition 74 is installed in the lower storage container 6b. Further, since the receiving groove 74c and the bottom surface convex portion 77 have a so-called labyrinth structure that is intricately engaged with each other, there is an effect of preventing the movement of gas between the front storage space 6b1 and the rear storage space 6b2. .

  At the upper center of the vegetable compartment partition 74, the vegetable compartment partition 74 and the upper storage container 6c are locked to each other via a latch 83 (“first engagement means” described in claims) provided in the latch means 80. In addition, a latch receiver 75 (“second engagement means” recited in the claims) is provided for unlocking.

  The position where the latch 83 and the latch receiver 75 are fitted and locked is such that the upper storage container 6c is fitted to the lower storage container 6b by dropping by the concave portion 70 and the convex portion 71. Therefore, when locked, the upper storage container 6c and the lower storage container 6b are fitted by dropping on the left and right side surfaces, and the center is locked via the latch means 80 and the vegetable compartment partition 74. Therefore, the positioning of the upper storage container 6c is reliable.

  The vegetable compartment partition 74 is inserted along the partition guide 76 provided in the lower storage container 6b, and is attached to the lower storage container 6b. Here, the lower side and the rear side of the left and right side surfaces of the vegetable compartment partition 74 form a recess 74d from which the ridgeline is removed. Of the partition guide 76 provided in the lower storage container 6b, a convex portion 76b is provided at a position corresponding to the concave portion 74d of the vegetable compartment partition 74, and the concave portion 74d and the convex portion 76b are arranged so as not to interfere with each other. Yes.

  On the other hand, when trying to insert the vegetable compartment partition 74 back and forth, right and left, or up and down into the partition guide 76, the convex portion 76b of the partition guide 76 interferes with the partition frame 74b. It cannot be attached at a predetermined position along the partition guide 76. Therefore, when trying to set the vegetable compartment partition 74 in the wrong direction, the user can easily recognize the error.

  Accordingly, the vegetable compartment partition 74 is correctly set in a predetermined direction with respect to the lower storage container 6b in the up / down, left / right, and front / rear directions, and is not set in the reverse direction. There is an effect that it can be securely mounted.

  FIG. 16 is an exploded perspective view showing the configuration of the vegetable compartment 6. The support rollers 58 provided on the support rails 55 provided at the left and right ends of the vegetable compartment door 6 a and projecting rearward are provided inside the refrigerator body 1. It is slidably inserted into a main body rail 59 provided in the box 10a along the front-rear direction. Furthermore, by placing the support rail 55 on the main body roller 56, the vegetable compartment door 6a is configured to move in the front-rear direction and open and close. The lower storage container 6b is placed on the left and right support rails 55, and the vegetable compartment partition 74 is set by being inserted downward from above along the partition guide 76 provided in the lower storage container 6b. 6c is a structure mounted in the lower storage container 6b.

  When the vegetable compartment partition 74 is set in the lower storage container 6b, the lower storage container 6b is divided into the front storage space 6b1 and the rear storage space 6b2 by the vegetable compartment partition 74 as described above. Here, the front storage space 6b1 in front of the vegetable compartment partition 74 is a space used for storage of tall food such as bottles and beverages in containers, and is an area opened to the space in the inner box 10a. It becomes.

  On the other hand, when the vegetable compartment 6 is closed, the rear storage space 6b2 is configured to be in an appropriate airtight state close to hermeticity by the vegetable compartment partition 74 and the upper storage container 6c.

  That is, the lower surface of the vegetable compartment partition 74 is partitioned by a labyrinth structure of the bottom convex portion 77 of the lower storage container 6b and the receiving groove 74c of the vegetable compartment partition 74, and the left and right side surfaces of the vegetable compartment partition 74 are fitted in the grooves of the partition guide 76. It is the structure which prevents passage of gas.

  The rear surface of the rear storage space 6b2 is partly sealed in contact with the packing 69 provided in the width direction of the lower surface of the upper storage container 6c, and the cool air discharged from the outlet 25a is discharged from the lower storage container 6b. It is prevented from flowing into the rear storage space 6b2.

  On the other hand, the upper storage container 6c is fitted to the left and right side surfaces and the bottom rear ends of the lower storage container 6b via a gap 65 provided between the upper storage container 6c and the lower storage container 6b shown in FIG. The cool air discharged from the discharge port 6c into the inner box 10a flows through the gap 65 into the rear storage space 6b2 of the lower storage container 6b by a minute amount.

  Here, an example of the dimension of the gap 65 is about 2 mm to 3 mm. If the gap 65 is too large, the cold air from the outlet 25a flows too much into the lower storage container 6b, causing a problem that the humidity in the lower storage container 6b is reduced and the vegetables are dried. On the other hand, if the gap 65 is too small, the air in the rear storage space 6b2 is not agitated, so the temperature distribution in the lower storage container 6b increases and the temperature decreases locally, causing condensation on part of the wall surface. The problem that it is easy to occur arises.

  Therefore, it is preferable to provide an appropriate airtight state close to a sealed state while providing an appropriate gap such that only a small amount of cold air flows into the rear storage space 6b2.

  Since the rear storage space 6b2 is in a moderate airtight state close to a sealed state, the humidity in the rear storage space 6b2 is maintained at a high humidity near 100% due to moisture generated from the stored vegetables. Furthermore, excessive moisture that condenses on the wall surface is released to the outside of the lower storage container 6b by the moisture absorption and release means 62, so that the freshness of the vegetables is maintained and the condensed water is applied to the wall surface and bottom surface of the lower storage container 6b. Since it does not adhere as water droplets, there is an effect that the freshness of vegetables is maintained.

Next, the structure of the latch means 80 provided in the front center part of the upper storage container 6c will be described with reference to FIGS.
FIGS. 17A and 17B are perspective views of the latch means 80 in the present embodiment, where FIG. 17A is a diagram viewed from the diagonally upper front, and FIG. 17B is a diagram viewed from the diagonally lower rear.
FIG. 18 is a perspective view showing a procedure for attaching the latch means 80 in the present embodiment to the upper storage container 6c, which are attached in the order of FIGS. 18 (a), 18 (b), and 18 (c).
19 is a cross-sectional view taken along the line GG in FIG.

  In FIG. 17, a latch means 80 includes a latch case 81 constituting an outer shape, and a handle 82 operated by a user on a front surface, an upper surface, and a part of a rear surface of a central portion of the latch means 80 (“operating means according to claims”). ]). On the lower surface of the latch means 80 is a latch 83 that moves up and down in conjunction with the operation of the handle 82, and an attachment claw for attaching the latch means 80 to the upper storage container 6c closer to the left and right side surfaces than the latch 83. 84 is provided.

  Near the upper ends of the left and right side surfaces of the latch means 80, there are a boss receiving groove 85 for attachment to the upper storage container 6c, and an elastic rib 86 covering a part of the groove connecting the boss receiving groove 85 to the rear surface of the latch means 80. Is provided.

  On the rear surface side of the latch means 80, there is provided a groove portion 88 that meshes with a mounting rib 87 provided in the upper storage container 6c.

  The boss receiving groove 85 is formed in the vertical direction, and a groove is formed in the front-rear direction from the lower end of the boss receiving groove 85 (see FIG. 18). That is, a substantially L-shaped groove shape is formed by the boss receiving groove 85 and the groove. The groove is for guiding the mounting boss 90 to the boss receiving groove 85 when the latch means 80 is attached to the upper storage container 6c. The elastic rib 86 covers a part of the groove after the mounting boss 90 is inserted into the groove against the elastic force of the elastic rib 86. Thereby, after attaching the latch means 80 to the upper storage container 6c, since the groove is covered with the elastic rib 86, the groove is not conspicuous in appearance and the design is improved.

  Here, the vegetable compartment partition 74 is disposed between the thicknesses of the latch means 80 in the front-rear direction, and a latch 83 that is moved up and down by the handle 82 is provided near the front of the latch means 80, and is provided at the top of the vegetable compartment partition 74. The latch receiver 75 is configured to be fitted. Therefore, the protrusion of the front surface of the latch means 80 from the front surface of the vegetable compartment partition 74 can be reduced. Furthermore, since the front surface of the latch means 80 and the front surface of the upper storage container 6c are substantially flush with each other, the protrusion of the latch means 80 with respect to the front storage space 6b1 of the lower storage container 6b can be reduced. This is preferable because it does not hinder food in and out of the front storage space 6b1.

  Next, the operation of attaching the latch means 80 to the upper storage container 6c will be described with reference to FIGS.

  The upper storage container 6c is provided with latch means mounting side surfaces 89 corresponding to the left and right side surfaces of the latch means 80, and the latch means mounting side surfaces 89 are provided with mounting bosses 90 protruding inward. In other words, the mounting boss 90 is provided at a position facing the left and right side surfaces of the latch means (operation means) 80. A claw receiving hole 91 corresponding to the attachment claw 84 is opened on the lower surface of the upper storage container 6 c corresponding to the lower surface of the latch means 80. In other words, the claw receiving hole 91 is provided at a position facing the lower surface of the latch means (operation means) 80. Furthermore, a mounting rib 87 protruding forward is provided corresponding to the groove 88 of the latch means 80. In other words, the mounting rib 87 is provided at a position facing the rear surface of the latch means (operation means) 80.

  As shown in FIG. 18 (a), the latch means 80 is disposed so that the front surface thereof is substantially upward, and the mounting bosses 90 provided on the upper storage container 6c are left and right side surfaces of the latch means 80 while deforming the elastic ribs 86. The boss receiving groove 85 provided in

  Next, as shown in FIG. 18B, the latch means 80 is rotated around the mounting boss 90 in the direction of the arrow, and the mounting rib 87 is fitted into the groove portion (rear surface groove portion) 88.

  Further, as shown in FIG. 18C, the latch means 80 is rotated until the front surface of the latch means 80 substantially coincides with the front face of the upper storage container 6c, and the mounting claws 84 provided on the lower surface of the latch means 80 are moved to the upper storage container 6c. As shown in FIG. 19, the fitting boss 90 and the boss receiving groove 85 are fitted, the groove portion 88 and the mounting rib 87 are fitted, and the mounting claw 84 and the claw are further fitted. By latching with the receiving hole 91, the latch means 80 is attached to the front center part of the upper storage container 6c.

  That is, the latch means (operation means) 80 is configured to be rotatable around the mounting boss 90 in a state where the mounting boss 90 is engaged with the boss receiving groove 85, and in a range in which the latch means 80 rotates around the mounting boss 90. At a predetermined position, the mounting rib 87 engages with the groove (rear surface groove) 88 and the mounting claw 84 engages with the claw receiving hole 91.

  Conversely, from the state shown in FIGS. 18 (c) to 19, for example, a thin stick is inserted into the claw receiving hole 91 to deform the attachment claw 84 upward to release the hook by the attachment claw 84, and If the lower part is pulled forward, the state shown in FIG. 18B is obtained. If the elastic rib 86 is further elastically deformed inward, the mounting boss 90 is removed from the boss receiving groove 85, and the latch means 80 is moved to the upper storage container 6c. Can be removed from.

  After the latch means 80 is removed from the upper storage container 6c, only the upper storage container 6c can be washed with water, so that the upper storage container 6c can be kept clean.

  Next, the internal configuration of the latch means 80 will be described with reference to FIGS.

20 is a perspective view showing the internal structure of the latch means 80 in this embodiment. FIG. 20 (a) shows a state where the user does not operate the handle 82, and FIG. 20 (b) shows a state where the user operates the handle 82. Indicates the state.
21A is a cross-sectional view taken along the line HH in FIG. 20A, and FIG. 21B is a cross-sectional view taken along the line JJ in FIG.
FIG. 22 shows the operation of the latch 83 when closing the upper storage container 6c, and is a cross-sectional view corresponding to the HH cross section of FIGS. 20 (a) to 20 (b).
FIG. 23 is a view of the latch means 80 as seen from the front.

  20 to 23, the handle 82 is pivotally supported around a handle fulcrum 92 provided on the lower side of the latch means 80 in the vertical direction. When the handle 82 is operated, the handle 82 is supported. Is configured to rotate around the handle fulcrum 92 so that the upper surface of the handle 82 moves backward and can be restored again.

  Here, since the thickness of the handle 82 in the front-rear direction is made equal to the thickness of the flange portion 66 disposed around the upper storage container 6c, the handle 82 is stored in the front storage space 6b1 or the upper storage of the lower storage container 6b. This is preferable because it does not make a business trip in the container 6c and the amount of food can be secured.

  The bell crank 93 (“operating direction changing means” described in claims) is pivotally supported around bell crank fulcrums 95 provided at the left and right ends of the bell crankshaft 94. The pair of first arms 96 (the “first arm portions” described in the claims) on the drive side projecting obliquely upward in a direction approaching the handle 82 from the bell crankshaft 94 is larger than the width of the handle 82. It is arranged on the inner side and is in contact with an arm pushing portion 97 which is a protrusion provided on the rear surface side of the front surface of the handle 82.

  In the vicinity of the inside of the bell crank fulcrum 95 at each of the left and right ends of the bell crankshaft 94 and outside the width of the handle 82, a direction different from the first arm 96, that is, a direction close to the handle 82. A pair of second arms 98 (the “second arm portions” recited in the claims) on the driven side projecting obliquely downward are provided. Note that the bell crank fulcrum 95 and the second arm 98 have a latch case 81 positioned in the front and rear, and the first arm 96 is positioned between the handle 82 and the latch case 81 (see FIG. 23). .

  Since the second arm 98 and the latch arm 99 are arranged in the latch case 81 on the left and right outside of the handle 82, the handle 82 and the second arm 98 or the latch arm 99 even if the handle 82 rotates. Does not interfere with.

  Therefore, in the right side sectional view shown in FIG. 21B, when the handle 82 is rotated to release the lock, the front surface of the handle 82 overlaps the second arm 98 or the latch arm 99. Therefore, the handle 82 and the bell crankshaft 94 can be disposed close to each other, and the latch means 80 can be reduced in thickness.

  A latch 83 is provided at the center of the lower surface of the latch means 80 so as to be movable in the vertical direction.

  The tip of the second arm 98 provided in the vicinity of the left and right ends of the bell crankshaft 94 is a latch arm 99 (provided in claims) provided integrally in a substantially upward U-shape at both ends in the left and right direction of the latch 83. “Third arm portion”) and a latch arm fulcrum 100 are pivotally connected. When the latch arm 99 moves upward, the latch 83 is configured to move upward together with the latch arm 99.

  The latch 83 is detachably provided with the latch receiver 75 provided at the center of the upper end of the vegetable compartment partition 74 described above. The rearwardly facing surface of the lower end of the latch 83 is generally vertical, and the forwardly facing surface has an inclined shape toward the rear toward the lower side.

  Here, the second arm 98 and the latch arm 99 are provided in a range outside the handle 82 in the latch case 81, and even if the handle 82 rotates, the handle 82 and the second arm 98 or the like. The latch arm 99 is arranged so as not to interfere.

  Further, the latch 83 is disposed at a substantially lower projection position with respect to the latch arm fulcrum 100 that receives the force from the bell crank 93 via the second arm 98. Therefore, since the force received by the latch arm 99 from the second arm 98 coincides with the direction in which the latch 83 rises, no bending moment is generated, and therefore the operation of the latch 83 is stabilized without the latch 83 being inclined. There is an effect that.

  A compression spring 101 as an urging means is stretched between the latch 83 and the lower surface of the handle 82. When the handle 82 is not operated, the latch 83 is urged downward by the action of the compression spring 101. This is a configuration.

  At the upper end of the detachable vegetable compartment partition 74, a latch receiver 75 for locking the latch means 80 or the upper storage container 6c in engagement with the latch 83 is provided. The upper end of the latch receiver 75 has a rising surface in a substantially vertical direction on the front side, and prevents the latch 83 from moving backward in a state where the latch 83 is engaged and locked with the latch receiver 75. Yes. On the other hand, the surface of the latch receiver 75 on the front side that is raised in the substantially vertical direction and directed rearward is an inclined surface.

  In a state in which the latch 83 and the latch receiver 75 are fitted together, the concave portions 70 provided at the upper ends of the left and right sides of the lower storage container 6b and the convex portions provided at the mounting portions 67 on the left and right sides of the upper storage container 6c. 71 are fitted to each other and are positioned by so-called dropping. In other words, the lower fitting container 6b and the upper container 6c are arranged so that the fitting position of the drop due to the unevenness between the containers and the fitting by the latch receiver 75 provided in the latch 83 and the vegetable compartment partition 74 occur simultaneously. Yes.

  Next, the operation of the latch means 80 will be described.

  FIGS. 20A and 21A show a state in which the latch 83 is hooked on the latch receiver 75 without operating the handle 82, and the latch 83 has moved most downward by the urging force of the compression spring 101. FIG. In position. That is, the latch 83 protrudes downward. Since the latch arm fulcrum 100 is urged downward, in FIG. 21, the bell crank 93 is urged to rotate counterclockwise, and the first arm 96 is applied to the arm pushing portion 97 provided on the handle 82. The handle 82 is biased in a counterclockwise direction.

  The latch 83 is in a lowered position, and the lower end of the latch 83 is fitted with a latch receiver 75 provided at the upper end of the vegetable compartment partition 74 to lock the upper storage container 6c against the vegetable compartment partition 74 so as not to move backward. It becomes a state.

  FIGS. 20B and 21B show a state in which the handle 82 is operated and the latch 83 is disengaged from the latch receiver 75. The handle 82 rotates around the handle fulcrum 92 in the clockwise direction in FIG. It is in a moving state.

  Since the arm pushing portion 97 moves rearward, in FIG. 21, the first arm 96 rotates clockwise around the bell crank fulcrum 95 similarly to the handle 82, and the second arm 98 also rotates clockwise. Move. Since the second arm 98 rotates clockwise, the latch arm fulcrum 100 moves upward and the latch 83 moves upward. Since the lower end of the latch 83 is separated upward from the latch receiver 75 provided at the upper end of the vegetable compartment partition 74 and the fitting is released, the upper storage container 6c can move backward with respect to the vegetable compartment partition 74. That is, the lock is released.

  That is, by moving the handle 82 rearward, the latch 83 is raised, and the vegetable compartment partition 74 and the latch means 80 are unlocked.

  Here, since the latch 83 is provided in the vicinity of the front surface of the latch means 80, the distance from the front surface of the vegetable compartment partition 74 to the front surface of the latch means 80 is small. That is, since the latch means 80 or the front surface of the upper storage container 6c does not protrude from the front storage space 6b1 of the lower storage container 6b, it does not hinder food in and out of the front storage space 6b1. is there.

  As described above, the pair of second arms 98 and the latch arms 99 are provided in the latch case 81 near the left and right ends of the bell crankshaft 94 with the handle 82 interposed therebetween. Accordingly, when the handle 82 is operated to rotate the bell crank 93 shaft, the latch arm 99 rises equally to the left and right. Accordingly, the latch 83 provided on the lower side of the center of the latch arm 99 rises evenly to the left and right without tilting, so that the operation of the latch 83 is stable and the lock release is surely achieved.

  Next, the operation when the upper storage container 6c is moved rearward and closed from the opened state will be described with reference to FIG. FIG. 22A shows a state where the lock by the latch means 80 is released, the upper storage container 6c is moved rearward, and the opening 102 of the rear storage space 6b2 is generated. In this state, the latch 83 and the latch receiver 75 are not in contact with each other and are in a free state.

  Here, the structure of the latch 83 and the latch receiver 75 when the upper storage container 6c is moved in the forward arrow direction and closed will be described.

  As described above, the front face of the lower end of the latch 83 has an inclined shape (inclined face 106) closer to the rear as it goes downward. Further, the surface on the rear side of the upper end of the latch receiver 75 is an inclined surface (inclined surface 106) that protrudes upward toward the front. With these configurations, when the upper storage container 6c is closed, the inclined surface of the latch 83 and the inclined surface of the latch receiver 75 come into contact with each other, so that the latch 83 is attached to the compression spring 101 as shown in FIG. The bell crankshaft 94 is pushed upward against the force, and the bell crankshaft 94 rotates clockwise through the second arm 98. If the upper storage container 6c is further moved forward from the state of FIG. 22 (b), the latch 83 gets over the latch receiver 75 to the state of FIG. 21 (a), and the upper storage container 6c or the latch means 80 is vegetables. The locked state is returned to the chamber partition 74.

  Next, with reference to FIG. 21, a configuration in which a so-called click feeling is applied to the handle 82 when the lock is released by operating the handle 82 will be described. For example, when the handle 82 is operated, the click feeling is caused by the operation of the handle 82 by giving a characteristic that the initial load when starting to move from a stationary state is large and the load decreases sharply after starting to move. The latch 83 releasing operation can be clearly transmitted to the tactile sense of the user.

  In this embodiment, as shown in FIGS. 21A and 21B, a flexible leaf spring portion 103 is extended from the bell crankshaft 94 toward the handle 82, and the tip of the leaf spring portion 103 is provided, for example, The cylindrical tip 104 is brought into contact with the recess 105 provided on the back surface of the handle 82 by an elastic deformation of the leaf spring 103 with an appropriate pressure contact force. As an example, if the bell crankshaft 94 is molded from polyacetal resin, the first arm 96, the second arm 98, the leaf spring portion 103, and the tip portion 104 may be integrated with the bell crankshaft 94. Good.

  As shown in FIG. 21A, when the latch 83 is fitted and locked to the latch receiver 75, the tip 104 is fitted in the recess 105. When the operator moves the handle 82 rearward and the bell crankshaft 94 starts to rotate, the leaf spring 103 is elastically deformed and the reaction force increases, so the operating force of the handle 82 increases. When the handle 82 is further moved rearward, the tip 104 moves away from the recess 105 and moves upward, and comes into contact with the back surface of the handle 82 as shown in FIG. At the moment when the tip 104 is removed from the recess 105, the contact position of the tip 104 changes abruptly and the reaction force decreases. Therefore, the operating force of the handle 82 is rapidly reduced, which is preferable because a so-called click feeling can be imparted.

Next, the operation of opening the upper storage container 6c by operating the latch means 80 will be described with reference to FIGS.
24 (a) to 24 (c) show a series of operations of moving the upper storage container 6c backward by operating the handle 82 to release the lock by the latch 83 after opening the vegetable compartment door 6a. Show.

  FIGS. 25A to 25E show a series of operations from opening the vegetable compartment 6 to putting food in and out of the lower storage container 6b and closing it.

  When the vegetable compartment 6a is opened to the front, the latch 83 is fitted with a latch receiver 75 provided in the vegetable compartment partition 74, so that the upper storage container 6c is opened together with the lower storage container 6b, FIG. 7 to 21A, the front surface of the upper storage container 6c is positioned close to the front surface of the vegetable compartment partition 74.

  Here, as shown in FIG. 24 (b), when the handle 82 is moved in the direction indicated by the arrow, that is, backward, the latch 83 is moved upward as shown in FIG. 21 (b) and is fitted into the latch receiving groove 74c. Since the match is released, the upper storage container 6c is movable backward. Here, if a force of a predetermined level or more is further applied to the handle 82 in the rearward direction, the fitting due to the drop of the convex portion 71 of the upper storage container 6c and the concave portion of the lower storage container 6b is released, and the upper storage container 6c moves rearward. .

The food can be taken in and out through the opening 102 in the rear storage space 6b2 of the lower storage container 6b.

  Next, still another embodiment of the latch mechanism will be described with reference to FIG.

  FIG. 28 is a front view of the latch means 80 and a part of the upper storage container 6c of another embodiment different from FIG. 27, as viewed from the front. The difference from the first embodiment shown in FIGS. 1 to 26 is that when the latch 83 is raised, the handle 82 is moved downward rather than backward. That is, the handle 82 and the latch 83 are supported so as to be movable up and down, and are urged so as to be separated from each other by the spring 111 as urging means. A pair of second fulcrums 109 are provided inside the left and right side surfaces of the handle 82, and a pair of third fulcrums 110 are provided on the latch 83. The pair of link plates 112 are pivotally supported around a first fulcrum 108 provided substantially in the middle between the second fulcrum 109 and the third fulcrum 110, one end being the second fulcrum 109 and the other end. Are pivotally supported by the third fulcrum 110, respectively.

  As shown in FIG. 28 (b), when the handle 82 is moved downward, the second fulcrum 109 moves downward together with the handle 82, the link plate 112 rotates, and the third fulcrum 110 is opposite to the fulcrum 2. Therefore, the latch 83 rises together with the third fulcrum 110. That is, the latch 83 is separated from the latch receiver 75 and is unlocked.

  Next, as shown in FIG. 28 (b), if the handle 82 is moved backward while the handle 82 is pushed down, the upper storage container 6c or the latch means 80 is moved backward because the lock has already been released. The food can be taken in and out through the opening 102 in the rear storage space 6b2 of the lower storage container 6b.

  According to this embodiment, the detachable vegetable compartment partition 74 that partitions the lower storage container 6b in the front and rear in the vegetable compartment is provided close to the front surface of the upper storage container 6c, and the lower storage container 6b further includes a moisture absorption / release means 62.

In addition, the rear rear storage space 6b2 can maintain high humidity close to 100% humidity and prevent condensation, so that it is possible to provide a refrigerator capable of maintaining the freshness of vegetables.

  In addition, the lower storage container 6b is separated by a detachable partition 74 and an upper storage container 6c to obtain a moderate airtight state close to a substantially hermetically sealed state, maintaining the interior at high humidity and preventing condensation, and the vegetable compartment It is automatically locked when is closed. Thereby, it is possible to provide a refrigerator that is suitable for maintaining the freshness of stored foods (special vegetables) and improved in usability.

  The lower vegetable compartment (storage case) has a front storage space suitable for storing tall foods such as beverages in commercially available containers, and a rear storage that maintains high humidity with a moderate airtight state close to a sealed state. A removable partition that divides the space is provided, and a latch receiver is provided on the upper surface of the partition. A latch that engages and disengages from the latch receiver by moving up and down by a handle operation is provided at the front of the upper vegetable compartment. When the vegetable compartment is closed, the latch provided in the upper vegetable compartment (small case) gets over the latch receiver of the partition and is automatically locked. Thereby, even if a user does not operate an operation lever each time, while a rear storage space can maintain high humidity, a lock is reliable and usability improves.

  According to this embodiment, since the removable vegetable compartment partition 74 was comprised with the transparent glass plate, there exists an effect that the food accommodated in the rear part storage space 6b2 can be visually confirmed from the front.

  According to the present embodiment, the detachable vegetable compartment partition 74 can be attached to the vegetable compartment partition 74 when the latch receiver 75 is to be installed in the opposite direction other than the correct orientation in which the latch receiver 75 can be fitted to the latch 83. The concave portion 74d and the convex portion 76b provided on the partition guide 76 interfere with each other and are not attached. Therefore, since the vegetable compartment partition 74 cannot be attached in the reverse direction, the positional relationship between the latch 83 and the latch receiver 75 is constant, and the latch 83 can be securely fitted into the latch receiver 75 and locked. There is.

  According to this embodiment, the latch 83 and the latch receptacle 75 provided in the vegetable compartment partition 74 lock the upper storage container 6c and the vegetable compartment partition 74, and the upper storage container 6c is formed by the recess 70 and the projection 71. Since the position where the lower storage container 6b is fitted is adjusted by dropping, the upper storage container 6c and the lower storage container 6b are fitted by dropping on both the left and right sides, and further, the latch part 80 and the vegetable compartment partition at the center. It is locked via 74. Therefore, the positioning of the upper storage container 6c is reliable, and there is an effect that the inside of the rear storage space 6b2 surrounded by the lower storage container 6b, the vegetable compartment partition 74, and the upper storage container 6c can be maintained in an appropriate airtight state. is there.

  Further, according to the present embodiment, the latch means 80 including the latch 83 that moves up and down by the operation of the handle 82 is provided near the center of the front portion of the upper storage container 6c. It provided in the upper end of the vegetable compartment partition 74 arrange | positioned detachably with respect to the storage container 6b.

  Since the latch 83 and the latch receiver 75 are engaged with each other, the upper storage container 6c is locked with respect to the lower storage container 6b and the vegetable compartment partition 74, so that the lower storage container 6b, the vegetable compartment partition 74 and the upper storage are provided. Since the rear storage space 6b2 of the lower storage container 6b surrounded by the container 6c can be in an appropriate airtight state suitable for maintaining high humidity, a refrigerator capable of maintaining the freshness of vegetables can be provided. There is an effect.

  Since the vegetable compartment partition 74 is configured to be detachable, when the vegetable compartment partition 74 is removed, large foods that cannot be accommodated by either one of the front storage space 6b1 or the rear storage space 6b2 can be stored. . Furthermore, since the latch receiver 75 is removed as a unit with the vegetable compartment partition 74, the upper storage container 6c is not locked. Therefore, there is no need to operate the handle 82 to release the lock when moving the upper storage container 6c rearward after the vegetable compartment 6 is opened, and there is an effect that it is possible to provide a refrigerator with excellent handleability.

  Furthermore, according to the present embodiment, packing is provided between the rear side of the lower storage container 6b and the bottom surface of the upper storage container 6c so that the rear side is airtight, while the left and right side surfaces of the lower storage container 6b are left and right. Since an appropriate gap is provided between the left and right side surfaces of the upper storage container 6c, the amount of cool air flowing from the outlet 25a into the rear storage space 6b2 of the lower storage container 6b can be appropriately controlled. There is.

  That is, there is no problem that the amount of cold air is too large and the humidity in the lower storage container 6b is lowered to dry the vegetables.

  In addition, since the amount of cold air is too small and the air in the rear storage space 6b2 is not agitated, the temperature distribution in the lower storage container 6b expands and a part of the wall surface is condensed due to a local temperature decrease. There is an effect which does not produce.

  Furthermore, according to the present embodiment, the front side of the upper storage container 6c and the surface facing the front of the latch means 80 are arranged substantially flush with the front side of the upper storage container 6c, and the latch means 80 is located at the lower stage. By making it thin so as not to make a business trip to the front storage space 6b1 of the storage container 6b, there is an effect that it does not interfere with the storage of the beverage or the like in the storage recess 61.

  Further, according to the present embodiment, when the upper storage container 6c is moved backward and moved from the opened position to the front and closed, the latch 83 gets over the latch receiving groove 74c provided in the vegetable compartment partition 74, Since it is configured to lock the space between the upper storage container 6c and the vegetable compartment partition 74, it is configured to automatically lock only by closing the upper storage container 6c, and there is no need to bother to lock when closing, There is an effect that an easy-to-use refrigerator can be provided.

  Since the latch means 80 in the present embodiment is provided with the handle 82 that is an operation portion that can release the locked state in which the upper storage container 6c and the vegetable compartment partition 74 are locked, the user operates the handle. As a result, the latch 83 is lifted, and the lock can be easily released and the upper storage container 6c can be moved rearward.

  In the refrigerator provided with the latch means 80 in the present embodiment, the latch 83 is lifted by moving the handle 82 rearward to release the lock. Therefore, after releasing the lock, the rearward force is continuously applied. In addition, the upper storage container 6c can move rearward and open, and the lower storage container 6b can be opened to allow food to be taken in and out, so that it is possible to provide a refrigerator that is easy to operate and easy to use.

  In the refrigerator provided with the latch means 80 in the present embodiment, even if the vegetable compartment 6 is closed from the state in which the vegetable compartment 6 is opened without moving the upper storage container 6c forward and locking it, the latch 83 and Since the latch 83 is fitted after the latch 83 has passed over the latch receiver 75 immediately before the vegetable compartment 6 is closed, the upper storage container 6c or the latch means 80 is locked to the vegetable compartment partition 74 when the vegetable compartment 6 is closed. This is a configuration.

  Therefore, it is easy to use because the lock can be automatically applied even if the user does not perform the lock operation. In other words, by simply closing the vegetable compartment door 6a, the rear storage space 6b2 of the lower storage container 6b can be kept in an appropriate airtight state, so that a refrigerator that maintains the freshness of the vegetables stored in the rear storage space 6b2 can be provided. There is an effect.

  In the present embodiment, the latch means 80 has the mounting boss 90 and the boss receiving groove 85 fitted, the groove 88 and the mounting rib 87 fitted, and the mounting claw 84 and the claw receiving hole 91 fitted. Therefore, the latch means 80 is configured to be attached to the center of the front surface of the upper storage container 6c, and the latch means 80 is configured to be removable from the upper storage container 6c, so that the upper storage container 6c can be washed with water. There is.

  Since the latch means 80 in the present embodiment is configured to transmit the rearward movement of the upper end of the handle 82 to the latch 83 via the bell crank 93 that changes the direction upward, the latch 83 is moved by moving the handle 82 rearward. There is an effect that the lock can be released by moving the button upward.

  Further, a first arm 96 on the driving side for transmitting force from the handle 82 to the bell crank 93 and a second arm 98 on the driven side for transmitting force from the bell crank 93 to the latch 83 are connected to the first arm 96. The arm 96 is arranged inside the left and right width of the handle 82, and the second arm 98 is arranged in a latch case 81 which is a fixed frame provided outside the left and right width of the handle 82. Since it does not interfere with the handle 82 even when it is turned, there is an effect that the latch means 80 can be thinned in the front-rear direction and a food storage space can be secured.

  Further, the second arm 98 of the bell crank 93 and the latch arm 99 integrally provided in a substantially upward U-shape at both left and right ends of the latch 83 are arranged symmetrically on both the left and right sides of the handle 82. Therefore, the latch 83 is pulled up evenly on the left and right sides by the second arm 98. Therefore, the operation of moving the latch 83 upward to release the lock is stable, and the lock release operation is reliable.

  Furthermore, a latch 83 is disposed almost directly below the latch arm fulcrum 100 that receives the force from the bell crank 93 via the second arm 98. Therefore, the force received by the latch arm 99 from the second arm 98 matches the direction in which the latch 83 moves upward, so that no bending moment is generated. Therefore, the latch 83 does not tilt and the operation of the latch 83 is stable. There is an effect that.

  In the present embodiment, the latch means 80 is provided by extending a flexible leaf spring portion 103 from the bell crankshaft 94 toward the handle 82, and the front end of the leaf spring portion 103 is, for example, a cylindrical tip portion 104. The plate spring portion 103 is in contact with the concave portion 105 provided with a moderate pressure contact force due to the elastic deformation of the leaf spring portion 103. When the handle 82 is moved rearward, the leaf spring 103 is elastically deformed and the reaction force increases, so that the operating force of the handle 82 increases. When the handle 82 is further moved rearward, the distal end portion 104 moves away from the concave portion 105 and moves upward. At that moment, the contact position of the distal end portion 104 changes abruptly and the reaction force decreases. Therefore, since a so-called click feeling can be imparted by sharply reducing the operating force of the handle 82, the latch 83 releasing operation due to the operation of the handle 82 can be clearly transmitted to the user's tactile sense, and an easy-to-use refrigerator is provided. There is an effect that can be done.
