Detailed description of the invention

Hereinafter, the most referring to the drawings, the mode (present embodiment) being used for implementing the present invention is said Bright.Additionally, in the accompanying drawing of following suitably reference, for simplifying diagram, as long as no special provision, have Time omit lower layers of containers 101 diagram.

Fig. 1 is the front view of the refrigerator 10 of present embodiment.Refrigerator 10 shown in Fig. 1 is at refrigerator main body 1 Front possess cold room left-hand door 2, the right door of cold room 3, ice-making compartment door 4a, quick freeze chamber door 4b, cold Chilling chamber door 5 and vegetable compartment door 6.Cold room left-hand door 2 can be to by upper hinge 7a and lower hinge 8a Paper nearby direction rotates.It addition, the right door of cold room 3 can be to by upper hinge 7b and lower hinge 8b Paper nearby direction rotates.That is, be set to can be split for cold room left-hand door 2 and the right door of cold room 3, and The space formed by them and refrigerator main body 1 is formed with cold room (not shown).

Further, ice-making compartment door 4a, quick freeze chamber door 4b and refrigerating chamber door 5 can be by paper nearby Direction pulls out.And, in the space formed by them and refrigerator main body 1, it is respectively formed with ice-making compartment, fast Speed refrigerating chamber and refrigerating chamber (the most not shown).Vegetable compartment door 6 similarly can be by paper nearby side To pull-out.It addition, in the space being made up of them and refrigerator main body 1, be formed with vegetable compartment 100 (to vegetables The reserves such as dish carry out the storeroom stored, with reference to Fig. 4).

Fig. 2 be represent when vegetable compartment 100 accommodates lower layers of containers 101, lower layers of containers 101 and on The axonometric chart of the inside of layer container 102.Sometimes at lower layers of containers 101, in addition to storage vegetable etc., also receive Receive bottled drink etc..In vegetable compartment 100, the interior case 124 of refrigerator main body 1 (with reference to Fig. 1) constitutes vegetable The wall (left wall, right wall and diapire) of room 100.Further, the vegetables of the top of vegetable compartment 100 it are configured at Dish jar (not shown) constitutes the upper wall of vegetable compartment 100.Therefore, in vegetable compartment 100, certain degree ground Ensure that lower layers of containers 101 and the closure of the respective inside of upper strata container 102.

In vegetable compartment 100, lower layers of containers 101 and upper strata container 102 be received into can to face side and Rear side (following, sometimes referred to as " along the longitudinal direction ") freely pulls out.But, in the present embodiment, Even if lower layers of containers 101 moves in the longitudinal direction, upper strata container 102 is in the inside of lower layers of containers 101 Position also will not change.But, user is by operation locked hand 106, it is also possible to pull out to face side Upper strata container 102.

In the rear side of vegetable compartment 100, it is formed with the machine for configuring compressor (not shown) etc. outside case Tool room (not shown).Further, side overleaf, it is configured with for lower layers of containers 101 and upper strata container The inside of 102 carries out the cold air blow-off outlet 141 cooled down.Therefore, compare in face side, diapire side overleaf Higher.Further, the separator 103 of glass is possessed at lower layers of containers 101.Thus, lower layers of containers 101 It is divided into two partitions.And, upper strata container 102 is configured in two partitions to lower layers of containers 101 The space of rear side cover.

Fig. 3 is the axonometric chart of the framework 161 of supporting lower layers of containers 101.In Fig. 3, not shown lower floor holds Device 101 by clamping framework 161 left and right sides in the way of supporting and fixing in framework 161.At framework 161 The left and right sides, possess the rail plate 179 for making internal container 101 move along the longitudinal direction respectively. Rail plate 179 is relative to the members of frame 180 of the side being fixed on not shown lower layers of containers 101 in Fig. 3 Fixing.Rail plate 179, by stretching along the longitudinal direction in the inside of vegetable compartment 100, pulls out or holds Receive lower layers of containers 101.Hereinafter, with reference to Fig. 7 etc., the details of the structure of this rail plate 179 will be entered Row explanation.

The rail plate 179 being provided to left and right is connected with framework 161 via framework fixed part 169 respectively.Separately Outward, in the face side of rail plate 179, possesses the door for fixing vegetable compartment door 6 (with reference to Fig. 1) solid Determine portion 162.User is installed on the vegetable compartment of this fixed part 162 by pulling out in face side or push Door 6, pulls out lower layers of containers 101 from vegetable compartment 100 or accommodates lower layers of containers 101 to vegetable compartment 100.

Further, possess in the way of the rear side of rail plate 179, the rail plate 179 about connecting Contact component 167.Thus, when lower layers of containers 101 is contained in vegetable compartment 100, by contact component 179 With the contacts side surfaces of interior case 124, accommodate lower layers of containers 101 swimmingly.

At the connecting portion 168 of the lower section being formed at framework 161, connect and have for assisting lower layers of containers 101 The container drive mechanism (not shown) of movement along the longitudinal direction.This container drive mechanism is DYN dynamic, User opens switch (not shown) by pressing, via connecting portion 168 will make lower layers of containers 101 to Face side or rear side move required power and put on lower layers of containers 101.

This container drive mechanism not in lower layers of containers 101 grade moves in whole intervals to lower layers of containers 101 give power, but user press open switch wait after only once lower layers of containers 101 is given to The power that face side or rear side move.That is, can be completely under face side pulls out by rail plate 179 The power of the degree of layer container 101 only once puts on lower layers of containers 101.Thus, lower layers of containers is just being pulled out The midway of 101, user easily makes lower layers of containers 101 stop at desired position.But, container drives The imparting of the power that motivation structure is carried out can also only give when lower layers of containers 101 moves to face side.

Fig. 4 is the axonometric chart representing the situation when framework 161 shown in Fig. 3 is contained in vegetable compartment 100.This Outward, although in order to simplify and not shown in Fig. 4, but it practice, be to be supported on framework at lower layers of containers 101 Under the state of 161, framework 161 and lower layers of containers 101 are contained in vegetable compartment 100.Further, slip is led Rail 179 (accommodating container pull-out holding mechanism) can be led along the case side of the left and right sides being located at interior case 124 Rail 178 (accommodating container pull-out holding mechanism, storeroom guide rail) is mobile.Rail plate 179 is along front and back To movement, thus carry out pull-out and the receiving of lower layers of containers 101.Hereinafter, with reference to Fig. 6, case side will be led The detailed structure of rail 178 illustrates.

Fig. 5 is the line A-A sectional view of Fig. 4.(following at the external member 184 constituting rail plate 179 To illustrate with reference to Fig. 7), it is provided with and can be formed at groove 189 inward turning of case side rails 178 (accommodating container pull-out accommodates the frame bearing 181 turning an edge case side rails 178 and move in the longitudinal direction Mechanism, rotary body).Accordingly, because frame bearing 181 rotates while moving along the longitudinal direction, so External member 184 (and rail plate 179) moves along the longitudinal direction.

Further, the pull-out mouth when the face side of vegetable compartment 100, specifically pull-out lower layers of containers 101 is attached Closely, possessing axle box bearing 182, this axle box bearing 182 is by contacting with the lower surface of members of frame 180 on one side Rotating makes members of frame 180 move along the longitudinal direction.This axle box bearing 182 is fixed on the side of interior case 124, Because members of frame 180 moves with the movement of lower layers of containers 101, thus rotate.Wherein, at members of frame 180 The lower section of rear side end be conformed with 176.Therefore, if making axle box bearing 182 rotate make frame Parts 180 move the position to regulation to face side, then this projection 176 abuts with axle box bearing 182, thus The mobile stopping of members of frame 180.

Fig. 6 is the figure of the case side rails 178 (storeroom guide rail) representing the medial surface being installed on interior case 124, Fig. 6 (a) is its axonometric chart, and Fig. 6 (b) is the line B-B sectional view of Fig. 6 (a), and Fig. 6 (c) is figure The line C-C sectional view of 6 (a).As shown in Fig. 6 (a), in the outside of groove 189 (in Fig. 6 (a) The sidepiece on right side), it is formed with the guide wall 190 for preventing frame bearing 181 from departing from midway.Wherein, When the molding of case side rails 178, it is difficult to be formed about guide wall 190 in its rear side end 191. Therefore, in order to prevent being partially disengaged of frame bearing 181 never guide wall 190, and there is no guide wall The flank 186 (rear side movement restricting member) being formed in part with for preventing frame bearing 181 from arriving of 190. That is, the rear side at case side rails 178 is formed with flank 186, and this flank 186 is used for being limited in case side leads The movement of the rearwardly side of the frame bearing 181 that the internal rotating of rail 178 moves.This flank 186 has conduct The function of the stop of frame bearing 181.

It addition, in the face side of groove 189, for possessing to moving of face side of framing mask bearing 181 Limiting component 183 (face side movement restricting member).The part of the groove 189 of limiting component 183 is installed The height (inside dimension) of inside shorter as shown in Fig. 6 (b).Therefore, even not installing limit Position parts 183 part (with reference to Fig. 6 (c)) in can be in rotary moving frame bearing 181, by install Limiting component 183, the also movement to face side of framing mask bearing 181.And, by framing mask bearing The movement of 181, also limits the movement of the external member 184 being provided with frame bearing 181.

Fig. 7 is to represent the structure for the rail plate 179 making lower layers of containers 101 move along the longitudinal direction Sectional view.In Fig. 7, relative to paper, nearby side is equivalent to the face side of refrigerator 10, and relative to Paper and inboard are equivalent to the rear side of refrigerator 10.It is installed on the frame bearing of the rear side of external member 184 181 (the most in the lump with reference to Fig. 5) rotate along the longitudinal direction in the groove 189 of case side rails 178 while Mobile.

On the other hand, the external member 184 possessing this frame bearing 181 itself is configured at case side rails 178 The outside of groove 189, move along the longitudinal direction together with frame bearing 181.That is, possesses external member 184 And the rail plate 179 constituted is configured at the outside of case side rails 178.In other words, case side rails 178 With rail plate 179 on the direction vertical with the moving direction of lower layers of containers 101 from face side observe Section view configures discretely.That is, case side rails 178 and rail plate 179 are with nonoverlapping in this section view Mode staggers in the lateral direction, is thus configured with case side rails 178 and rail plate 179.

Further, as described above, the side at lower layers of containers 101 is fixed with members of frame 180.It addition, The internal face (side contrary with the side being fixed with lower layers of containers 101) of members of frame 180, passes through rivet 187 are fixed with internals 185.That is, internals 185 is installed on lower layers of containers via members of frame 180 The lateral surface of 101.Therefore, with internals 185 via the movement along the longitudinal direction of members of frame 180, Lower layers of containers 101 moves the most along the longitudinal direction.

And, opposed with internals 185 with in the way of covering internals 185 at internals 185 It is configured with ball 188 between the external member 184 of ground configuration.This ball 188 is by one side and internals 185 contact while rotating with external member 184 both sides such that it is able to make internals 185 and external member 184 independently move.Therefore, rail plate 179 possess internals 185, external member 184 and Ball 188 and constitute.

Rail plate 179 possesses the internals 185 and external member 184 that can independently move like this And constitute, guarantee the pull-out amount of lower layers of containers 101 the most more.That is, will be described below details, But first, be integrally forming and after face side moves at internals 185 and external member 184, than The position of regulation is moved to face side by face side, only internals 185, thus guarantees that lower floor holds more The pull-out amount of device 101.

Though additionally, the most not shown, the lower surface of members of frame 180 as described above with axle box bearing 182 contacts.Therefore, when members of frame 180 moves along the longitudinal direction, members of frame 180 is supported on axle box bearing 182, make axle box bearing 182 rotate simultaneously and members of frame 180 moves along the longitudinal direction.

Further, as it is shown in fig. 7, the size of the groove 189 of case side rails 178 (length of above-below direction, interior Size) L1 is shorter than the size of rail plate 179 (length of above-below direction, outside dimension) L2.That is, ice In case 10, the slip with size L2 bigger than size L1 of the groove 189 of case side rails 178 is used to lead Rail 179.Therefore, it is possible to unrelated with size L1 of the groove 189 of case side rails 178, use and have enough The rail plate 179 of size L2.Therefore, guarantee the rigidity of rail plate 179 fully, and prevent Rail plate 179 is applied the load of local.Thus, the internal structure of pull-out after stopping when external member 184 During part 185, it is possible to prevent from causing the increase of the local of frictional force because ball 188 is applied the load of local, It is thus possible to lighter power pull-out lower layers of containers 101.

It addition, constitute in internals 185 and the external member 184 of rail plate 179, internals 185 are fixed on members of frame 180 by rivet 187.That is, with above-mentioned accommodating container to face side and the back of the body On the direction that the moving direction of face side shifting is vertical from the section view that face side is observed, have and compare external member The internals 185 of the area of section that the area of section of 184 is little is installed on lower layers of containers via members of frame 180 101.Thus, internals 185 and be fixed on the members of frame 180 of internals 185, lower layers of containers The cross sectional moment of inertia of 101 is relatively big, and the load of lower layers of containers 101 puts on the whole of internals 185 dispersedly Body.Therefore, the generation of the bigger frictional force of suppression local such that it is able to pull out lower floor with less power and hold Device 101.

Herein, with reference to Fig. 5 and Fig. 7 etc., each parts when face side pull-out lower layers of containers 101 are described Effect illustrate.Additionally, in the accompanying drawings, the most not shown lower layers of containers 101 is illustrated for simplifying.

If under the state (Fig. 5) that lower layers of containers 101 is contained in vegetable compartment 100, to lower layers of containers 101 Give for the power to face side pull-out lower layers of containers 101, then, together with lower layers of containers 101, be installed on down Members of frame 180 and the internals 185 of layer container 101 start to move to face side.The imparting of this power removes Outside the power of user pull-out vegetable compartment door 6 (with reference to Fig. 1), also by with connecting portion 168 (with reference to Fig. 3) The container drive mechanism connected is carried out.Further, the imparting of this power is the most only entered when mobile beginning Row once, afterwards, pulls out lower layers of containers 101 because of inertia to face side.

Now, constitute the ball 188 of rail plate 179 and external member 184, internals 185 it Between produce frictional force bigger.On the other hand, produce between the bottom surface of frame bearing 181 and groove 189 Frictional force, the frictional force produced between the bottom surface of axle box bearing 182 and members of frame 180 are smaller.Therefore, The bigger frictional force produced to the movement of face side of adjoint internals 185 is also via ball 188 Transmit to external member 184.Thus, together with the movement with lower layers of containers 101 and internals 185, External member 184 also moves to face side.

If frame bearing 181 rotates to face side while moving in the groove 189 of case side rails 178, then Frame bearing 181 abuts with the limiting component 183 being located at groove 189.Thus, the rotation of frame bearing 181 stops, The movement of the external member 184 possessing frame bearing 181 also stops.But, owing to ball 188 rotates, institute With can internals 185 movable independently with external member 184 after moving together with external member 184 Continue because of inertia to move to face side.

And, with the movement to face side of internals 185, members of frame 180 and be fixed with frame portion The lower layers of containers 101 of part 180 also continues to move to face side.Now, members of frame 180 is at axle box bearing 182 Upper make axle box bearing 182 rotate while moving to face side.Therefore, if members of frame 180 moves to front The position of the regulation of side, then be located at projection 176 and the axle box bearing 182 of the rear side bottom of members of frame 180 Abut.Thus, the mobile stopping of members of frame 180.Further, due to the mobile stopping of members of frame 180, institute Also stop with the movement of lower layers of containers 101.This state is to have pulled out lower layers of containers to face side to greatest extent The state of 101.

Fig. 8 is to represent in the state shown in fig. 4, pull out the feelings after lower layers of containers 101 from vegetable compartment 100 The axonometric chart of shape.When to greatest extent to face side pull-out lower layers of containers 101, constitute rail plate 179 External member 184 and internals 185 become by greatest extent to face side pull out after state.

Fig. 9 is the line D-D sectional view of Fig. 7.When pulling out lower layers of containers 101 to face side to greatest extent Time, as described above, the projection 176 of members of frame 180 contacts with axle box bearing 182.Further, though at Fig. 9 In not shown, but the frame bearing 181 (with reference to Fig. 5) of external member 184 also contacts with limiting component 183.

When Fig. 8 and as shown in Figure 9 when being completely pulled out lower layers of containers 101, lower layers of containers The load of 101 is supported by axle box bearing 182 and these 2, frame bearing 181.And, at axle box bearing 182 And between frame bearing 181, with limiting component 183 before and after in the size of length in direction is correspondingly configured with Portion's component 185.Therefore, the load down from lower layers of containers 101 becomes by this limiting component 183 The part supporting of length.Therefore, it is possible to prevent from axle box bearing 182 is applied bigger load partly, thus Power during pull-out lower layers of containers 101 can be reduced.

Be additionally, since can reduce pull-out lower layers of containers 101 time power, so also be able to reduce by with framework The size of the power that the container drive mechanism that the connecting portion 168 of 161 connects gives.Constitute therefore, it is possible to reduce The load of the motor (not shown) of container drive mechanism.Further, owing to pulling out to face side with less power Lower layers of containers 101, it is possible to prevent lower layers of containers 101 from excessively opening to face side.

Additionally, in above-mentioned example, accommodating container is as the lower layers of containers 101 being contained in vegetable compartment 100 Deng, if but be accommodated in the accommodating container of refrigerator 10, can also be arbitrary.Further, above-mentioned example In, the internals 185 that area of section is less is installed on the outside of lower layers of containers 101 via members of frame 180 Face but it also may in contrast, the external member 184 that area of section is bigger is installed on lower layers of containers 101 Lateral surface.Further, container drive mechanism power lower layers of containers 101 given in above-mentioned example only It is the most once but it also may persistently give in the period that lower layers of containers 101 moves.
