Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a lid member attachment device for, for example, an electric refrigerator.

For example, in a one-door electric refrigerator,
In order to protect the cooler or to improve the appearance when the refrigerator door is opened, a lid member such as an Eva cover is generally attached to the front of the cooler to be opened and closed. This lid member has conventionally been, for example,
A pair of bearing parts is fixed to the upper surface of an inner box constituting the cabinet by screws or adhesive, and the cabinet can be attached to the bearing parts via a hinge part.

However, with the conventional mounting structure, there is a risk that the hinge shaft may accidentally fall off at the bearing portion of the lid member, and the mounting strength is not very high, resulting in problems such as requiring time and effort to install.

The present invention provides a mounting device that allows the lid member to be easily installed and securely held without accidental falling off, and in which the bearing itself also serves as reinforcement for the inner box. Examples will be described in detail with reference to the drawings.

Figure 1 shows the appearance of an electric refrigerator to which this invention is applied.
It is a door type thing.

In the figure, reference numeral 1 denotes an inner box, which is integrally fixed to an outer box 2 forming the outer wall surface of the cabinet via a heat insulating material, etc., and together with this outer box 2 constitutes the main body cabinet. Reference numeral 3 denotes a refrigerator door attached to open and close the front of the inside of the cabinet, and various pockets are provided on the back of the refrigerator door.

At the top of the inner box 1, a cooler (evaporator) 4 is installed.
is disposed, and a temperature regulator 5 is disposed on one side below it, and its temperature sensing part (not shown) is attached to the cooler 4 or at a predetermined position inside the refrigerator. A lid member 10 is supported on the front surface of the cooler 4 so as to be openable and closable, to protect the cooler 4 and to give consideration to the appearance when the door 3 is opened. Note that 30 is a soup receptacle detachably attached below the cooler 4.

The inner box 1 is made of impact-resistant styrene resin or
It is made of synthetic resin such as ABS resin, and as shown in Figure 2, the flange part 1 is attached to the front by vacuum forming.
It has a substantially rectangular box shape with an open front surface. On the upper surface of the inner box 1, that is, on the upper surface where the cooler 4 is attached, a pair of bearing portions 6, 6 are formed to bulge inward at a predetermined interval. The bearings 6, 6 are for supporting the lid member 10, and are formed simultaneously and integrally with this when molding the inner box. The bearing portions 6, 6 may be open and communicated with the rear end surface of the inner box 1 as shown in the figure, or may be partially expanded on the upper surface of the inner box as shown in FIG. It may be something. The bearing parts 6, 6 are formed in a protruding and rib-like bulge, and themselves serve to reinforce the inner box 1. Since the lid member is supported by this reinforced portion, sufficient mounting strength can be maintained.

Figure 4 shows the main parts of the mounting device of the present invention. Bearing holes 7, 7 are positioned and drilled on both outer sides of the bearing parts 6, 6, respectively, and a pair of left and right plug-shaped plugs are provided in the bearing parts 7, 7. Bearing members 8, 8 are fitted. These bearing members 8, 8 are for reinforcement, and have a mounting hole 9 formed through them in the direction of their central axis.
Support shafts 11, 11 provided on the lid member 10 are inserted into and supported by this. A collar 8a is protruded from one end of the bearing member 8, and when the member 8 is inserted into the bearing hole 7, the member 8 is prevented from coming off in the insertion direction.

On the other hand, the cover member 10 is formed in a rectangular flat plate shape, and both sides of the cover member 10 are bent inwardly by a predetermined width.
A pair of support shafts 11, 11 are fitted in the mounting holes 9, 9 at the upper positions of both side portions 10a, 10a.
The cover member 10 is made of a material such as polystyrene resin having impact resistance and elasticity.

In order to attach this cover member 10 to the front surface of the cooler 4, the supporting shafts 11, 11 are inserted into the mounting holes 9 of the bearing members 8, 8 with both sides 10a, 10a slightly elastically expanded outward. 9 from the outside. This allows the support shafts 11, 11 to be attached to the mounting holes 9, 9.
The lid member 10 is rotatably supported by the bearings 6, 6 via the support shaft and the mounting hole. In this case, it goes without saying that the clearance between the mounting hole 9 and the support shaft 11 must be adjusted in advance so that the lid member 10 can be opened and closed smoothly and satisfactorily.

Thus, the lid member 10 is attached to the front surface of the cooler 4 at the upper part of the inner box so that it can be opened and closed.

Figure 5 shows another example of the proposed mounting device.
A pair of protruding pieces 1 are installed at a predetermined position on the upper part of the back of the lid member 6.
2 and 12 are formed to protrude at a predetermined interval in the longitudinal direction, and a pair of support shafts 13 and 13 are provided to protrude outward from each outer side of the protrusion pieces 12 and 12, respectively.

On the other hand, a bearing hole 1 is provided in each inner side of the bearing parts 6, 6.
4 and 14 are bored, and this bearing hole 1
The bearing member 8 is fitted onto the bearing portions 4 and 14 from inside the bearing portions 6 and 6. In this case, support shaft 1
3 and 13 are mounting holes 9 and 9 provided in the bearing member 8.
It will be inserted from inside. According to this, since the bearing parts 6, 6, etc., the inside of the inner box 1, etc. are completely shielded by the lid member 10, there is an advantage that the appearance of the door 3 is further improved when the door is opened.

It is also possible to provide the support shafts 13, 13 so as to protrude from each inner side of the projecting pieces 12, 12, as shown by the imaginary lines in FIG. In this case, it goes without saying that the bearing holes 14, 14 are bored in each outer side of the bearing parts 6, 6.

FIG. 6 shows still another embodiment of the mounting device of the present invention, in which rectangular bearing holes 18 are formed along the depth direction of the inner box 1 on both outer sides of the bearing parts 6, 6. Bearing members 19 are fitted into these, respectively. In this example, the bearing member 19 has a substantially rectangular block shape that is long in the depth direction, and has a flange 19a on the front surface thereof to prevent it from coming off. In addition, a substantially elongated guide hole 20 extending in the depth direction is bored in the front surface thereof, and a substantially circular guide hole 20 is formed at the inner depth of the hole 20 on the proximal end side, that is, on the front side of the inner box 1. , and a guide groove 21 that is narrow in the depth direction and parallel to the guide groove is integrally provided.

On the other hand, on the back surface of the lid member 10, a pair of protruding pieces 22, 22 are formed to protrude at a predetermined distance, and a pair of supporting shafts 23, 23 are protruded from each other inside each of the protruding pieces 22, 22. has been done.

The base end 23a of the support shaft 23 has a circular shape to be fitted into the guide hole 20,
The outer periphery of the distal end portion 23b is formed with a notch in the shape of a rectangular shaft having a slightly small diameter so that the distal end portion 23b can be fitted and guided into the narrow portion 21a of the guide groove 21.

The lid member 10 is attached to the bearing parts 6, 6 by fitting and supporting the support shafts 23, 23 into the bearing members 19, 19. According to this embodiment, the lid member 10 can be opened. Sometimes this is connected to the support shaft 23
When the support shaft 23 is rotated approximately 90 degrees upward using the support shaft as a fulcrum and then pushed into the inner box 1 in the depth direction, the base end 23a of the support shaft 23 will align with the guide hole 20, and the tip end 23b will align with the guide groove 21. It is movably fitted from the circular portion 21b to the narrow portion 21a, and is slid in the depth direction while being guided along these portions. As a result, the lid member 10 is supported in a cantilevered state by the tip end 23a of the support shaft 23 and the narrow portion 21a of the guide groove 21, so that the lid member 10 can be held in an open state. On the other hand,
To close the lid member 10, the lid member 10 may be pulled out to the front of the inner box. As a result, the base end 23a and the distal end 23b of the support shaft 23 slide forward along the guide hole 20 and the guide groove 21, and when the distal end 23b reaches the circular part 21b of the guide groove 21, the lid member 10 closes downward. This allows it to rotate in the direction of the lid.

In this embodiment, similarly to the above, bearing holes 18, 18 are provided inside the bearing parts 6, 6, and the bearing member 19 is fitted into the bearing holes 18, 18, and the lid member 10 is fitted into the bearing holes 18, 18.
The support shafts 23, 23 may be provided to protrude outward.

Furthermore, in each of the above embodiments, a case has been described in which this invention is applied to the attachment of a lid member that closes the front of a cooler of a small, one-door type electric refrigerator, but this invention is not limited to this. Rather, it is of course suitable for wide application to a general mounting structure for a lid member, in which a bearing component is provided in the inner box as described above, and a lid member is attached to the bearing component.

For example, a quenching chamber is provided near the ice making chamber2.
In door-type refrigerator-freezers, the cold air sent into the freezer compartment by a fan first enters the quenching chamber, where it cools the ice-making compartment, and then the cold air is sent from the quenching chamber to the freezer compartment. Generally, a cover is provided on the front of the quenching chamber to prevent the cold air sent into the quenching chamber from being directly sent out to other parts of the freezing chamber, thereby increasing the cooling efficiency of the icemaking chamber, or from a design standpoint.
Even in such cases, it is suitable to use the mounting device of the present invention.

In FIG. 1, an ice tray or the like is disposed at a predetermined position of the cooler 4, but detailed illustration thereof is omitted in this example.

As explained above, according to the mounting device of the present invention, the bearing part is integrally formed during molding of the inner box, and this bearing part also serves as a reinforcing rib, so the strength of the inner box can be increased without providing a separate reinforcing means. be enhanced. Further, the mounting structure of the support shaft is simple, and it can be easily fitted and supported. Furthermore, since the supporting portion of the support shaft is reinforced by the bearing member, reliable attachment and holding can be performed without accidental falling off.
