Description

Refrigerator with a door

Technical Field

The present invention relates to a refrigerator. More particularly, the present invention relates to a structure of a connection portion between a refrigerator main body side lead and a component side lead of various components provided at various locations in a refrigerator main body.

Background

In general, a refrigerator includes storage compartments such as a refrigerating compartment, a vegetable compartment, and a freezing compartment in a refrigerator main body. A temperature sensor is provided in a part of these storage chambers. Further, a damper or the like is provided in a duct for supplying cold air to the refrigerating chamber and the vegetable chamber. In the case of a temperature sensor, a damper, and the like, a lead wire in a back wall of a refrigerator main body is drawn out from the back wall and the like and connected to the temperature sensor, the damper, and the like, and a connection portion between the main body lead wire and a component lead wire of the temperature sensor, the damper, and the like is covered with a cover (see, for example, patent document 1).

Fig. 13A to 13C show a refrigerator described in patent document 1. In refrigerator 100 shown in fig. 13A to 13C, heater 102 is provided in vegetable compartment 101, and lead wire 103 of heater 102 is connected to body lead wire 105 drawn out from the rear wall of refrigerator body 104. The connection between the body lead 105 and the heater lead 103 is performed in a housing portion 106 recessed in the rear surface of the vegetable compartment. Further, the connector connection portion of the body lead 105 and the heater lead 103 is covered with a connector cover 107, and the connector cover 107 is fixed to the rear wall of the vegetable room by screws 108.

In the refrigerator 100 configured as described above, since the main body lead 105 and the heater lead 103 can be attached and detached from the vegetable compartment 101, the heater 102 has an advantage of being excellent in maintainability.

However, since the connector cover 107 covering the connector connection portion is fixed by the screw 108, there is a problem that the attachment and detachment of the connector cover 107 is troublesome, and high maintainability is not easily lowered.

In particular, the screw fastening portion is provided near the top surface of the vegetable compartment because the screw fastening portion is provided at a position deep in the vegetable compartment 101 and the connector cover 107 is provided near the top surface of the vegetable compartment so as not to be conspicuous. Therefore, there is a problem that it takes time and effort to prevent the screw fastening operation by the top wall and the side wall of vegetable compartment 101, and maintainability is greatly reduced.

Further, a recess 37 through which a lead wire 36 (see fig. 6) drawn out from the lighting device 22 through the middle of the shelf member 24 passes is formed in the front wall surface of the housing space 33. The connector 34a of the body lead 34 and the connector 36a of the lead 36 (see fig. 6) are housed in the connector housing chamber 30 in a mutually connected state.

At least two engaging portions 38 are provided in the connector housing chamber 30. In the present embodiment, a pair of engaging portions 38 are provided on both sides of the housing space 33 of the connector housing chamber 30. Further, in the connector housing chamber 30, pivot support portions 39 are provided on both sides of a rear portion which becomes a rear surface side of the low-temperature storage chamber 23.

As shown in fig. 5, the upper surface opening 31 of the connector housing chamber 30 is fitted with a cover 40 so as to cover the connector connection portion.

As shown in fig. 11A to 11D, the cover 40 is provided with locking portions 41A and 41b having elastic Rib (Rib) shapes at a near front side portion corresponding to the engagement portion 38 of the connector housing chamber 30. The cover 40 is further provided with a substantially L-shaped pivot support portion 43 at a rear portion thereof corresponding to the pivot support portion 39.

Further, in the lid 40, a stopper insertion portion 44 (see fig. 11A) is provided adjacent to the locking portion 41A on the side (left side in fig. 11A to 11D) of the locking portions 41A and 41b away from the protruding portion 17a of the cold air duct 17, and a stopper engagement portion 45 is provided at the lower end edge of the stopper insertion portion 44.

In addition, in the cover 40, a detachment prevention hole 46 is provided in a portion near the rear of the stopper insertion portion 44 so as to be connected to a position slightly shifted from the cold air duct 17 side, and a guide hole 47 is provided adjacent to the detachment prevention hole 46.

The cover 40 is attached to the upper surface opening 31 of the connector housing chamber 30 by engaging the locking

portions

41a and 41a with the engaging portion 38 of the connector housing chamber 30 by the elastic force thereof while the pivot support portion 43 is fitted into the pivot support portion 39 of the connector housing chamber 30.

As shown in fig. 8, the stopper member 48 is press-fitted into the stopper insertion portion 44, and the cover 40 attached to the upper surface opening 31 of the connector housing chamber 30 is fixed to the upper surface opening 31 of the connector housing chamber 30.

As shown in fig. 12A and 12B, a stopper locking portion 49 having a rod shape and having elasticity is provided on a stopper member 48 for fixing the cover 40 to the upper surface opening 31 of the connector housing chamber 30, and the stopper locking portion 49 is inserted into the stopper insertion portion 44 of the cover 40 and locked to the stopper engagement portion 45. As shown in fig. 12A, the stopper locking portion 49 has an inclined surface 49a with an inclined surface on the locking portion side.

Further, stopper member 48 is provided with a rod-shaped anti-separation portion 50 at a position slightly shifted from the cold air duct 17 side at a portion near the rear of stopper locking portion 49. The disengagement preventing section 50 is inserted into the disengagement preventing hole 46 of the cover 40, and is disposed along the locking section 41a of the cover 40 to restrict the movement of the locking

sections

41a and 41 b.

Further, the stopper member 48 is provided with a guide rod 51 fitted in the guide hole 47 of the cover 40.

Next, the operational effects of refrigerator 200 configured as described above will be described.

In the present embodiment, a case where the lead wire 36 of the lighting device 22 is connected to the body lead wire 34 is exemplified. Connection of body lead 34 to lead 36 of lighting device 22 body lead 34 led out from the rear wall of refrigerating compartment 7 and lead 36 of lighting device 22 led out from shelf member 24 are first connected within refrigerating compartment 7. The connected connector connection portion is accommodated in the accommodation space 33 together with the body lead 34 and the excess portion of the lead 36, and then the cover 40 is attached to the upper surface opening 31 of the connector accommodation chamber 30, and the trim cover 32 is further provided above the cover, thereby completing the connection work of the body lead 34 and the lead 36.

Here, the cover 40 covering the lead wire connection portion can be attached to the connector housing chamber 30 only by fitting the locking

portions

41a and 41b into the engaging portion 38 of the connector housing chamber 30, and the cover 40 can be attached and fixed to the upper opening 31 of the connector housing chamber 30 by a simple operation.

Further, since the stopper member 48 is engaged with one of the engaging portions of the locking

portions

41a and 41b of the cover 40 and the engaging portion 38 of the connector housing chamber 30 from the front surface side of the cover 40, the locking portion 41a and the engaging portion 38 are not accidentally disengaged. Thus, the cover 40 can be firmly fixed and held to the upper surface opening 31 of the connector housing chamber 30, similarly to the screw fastening, and the connector connection portion can be reliably protected.

Further, the stopper member 48 of the present embodiment is provided with a disengagement prevention portion 50 adjacent to the locking portion 41a that engages with the engagement portion 38 of the connector housing chamber 30, and the disengagement prevention portion 50 is disposed along the locking portion 41a of the cover 40 to restrict the movement of the locking portion 41 a. Therefore, the locking portion 41a of the cover 40 cannot move in the direction of disengaging from the engaging portion 38. Therefore, the cover 40 does not come off the locking portion 41a from the engaging portion 38 accidentally, and therefore, can be more firmly fixed and held while the locked state is reliably maintained.

Further, since the movement of the locking portion 41a is restricted by the disengagement preventing portion 50 as described above, the locking portion 41a on the side where the disengagement preventing hole 46 of the cover 40 is provided can be formed in a shape having a weaker engaging force. Therefore, the locking portion 41a of the cover 40 can be attached to or detached from the engagement portion 38 of the connector housing chamber 30 with a light force, and the operability of attaching and detaching the cover 40 can be improved.

In the present embodiment, the cover 40 is attached to the connector housing chamber 30 by engaging the locking

portions

41a and 41b of the cover 40 with the engaging portion 38 of the connector housing chamber 30 by merely fitting the pivot support portion 43 into the pivot support portion 39 of the connector housing chamber 30 and rotating and pressing the near-front side portion of the cover 40 toward the connector housing chamber 30.

Therefore, the cover 40 does not need to align the

locking portions

41a and 41b of the cover 40 with the engagement portion 38 of the connector housing chamber 30, and the workability of attachment of the cover 40 can be improved.

Further, since both the fitting of the cover 40 into the pivot support portion 39 and the pivoting of the cover 40 toward the connector housing chamber 30 can be performed downward, the mounting workability of the cover 40 can be dramatically improved as compared with the case where the cover is moved upward toward the ceiling surface.

Further, since the stopper member 48 has the guide rod 51 fitted in the guide hole 47 of the cover 40, the disengagement of the locking portion 41a can be more reliably prevented by the disengagement preventing portion 50.

That is, although the stopper member 48 is prevented from being disengaged by fitting the disengagement preventing portion 50 into the disengagement preventing hole 46 of the cover 40 to regulate the movement of the locking portion 41a along the locking portion 41a, the disengagement preventing portion 50 is constantly urged in the direction indicated by the broken-line arrow a in fig. 8 from the locking portion 41a, and the stopper member 48 is entirely inclined. Therefore, a force acts in a direction in which the engagement of the locking portion 41a is disengaged. However, the guide rod 51 fitted in the guide hole 47 functions to prevent the stopper member 48 from being entirely inclined by fitting in the guide hole 47. Therefore, the stopper member 48 is not inclined any more, and the locking portion 41a is more reliably prevented from being disengaged by the disengagement preventing portion 50.

Further, since the stopper member 48 has the inclined surface 49a on the stopper locking portion side surface of the stopper locking portion 49 for fixing the stopper member 48 itself to the lid 40, the stopper member 48 can be easily detached. That is, when a ruler or a driver or the like is inserted from above the surface of the lid 40 along the inclined surface 49a of the stopper locking portion 49 at the position indicated by X in fig. 12A, the stopper locking portion 49 moves in a direction of disengaging from the stopper engagement portion 45 of the lid 40 by a component force applied to the inclined surface 49 a. Therefore, the stopper member 48 is easily detached.

In addition, since the connector housing chamber 30 of the present embodiment is provided on the side of the protruding portion 17a of the cold air duct 17 provided on the rear surface of the low-temperature storage chamber 23, it can be provided without protruding into the low-temperature storage chamber 23. In addition, the following advantages are provided: the protrusion of the connector housing chamber 30 can be prevented while effectively utilizing the space on the side of the protruding portion 17a of the cold air duct 17.

Further, the decorative cover 32 provided above the cover 40 covering the upper surface opening of the connector housing chamber 30 and the upper surface of the shelf member 24 provided in contact with the rear surface of the storage chamber so as to insert the protruding portion 17a of the cold air duct 17 form substantially the same plane, and therefore, the appearance of the inner surface of the refrigerating chamber 7 can be improved virtually.

Further, the engaging portion 38 of the connector housing chamber 30 and the

locking portions

41a and 41b of the cover 40 are provided on a near side portion that is distant from the storage chamber back surface wall in the lateral direction of the cold air duct 17. The stopper 48 is configured to engage with an engaging portion between the engaging portion 38 on the side away from the cold air duct 17 and the locking portion 41 a. With this configuration, the stopper member 48 can be attached and detached without being obstructed by the side wall surface of the protruding portion 17a of the cold air duct 17 and the storage compartment rear wall, and the operability of attaching and detaching the cover 40 can be improved.

Although the refrigerator 200 according to the embodiment of the present invention has been described above, the present invention is not limited thereto, and various modifications can be made within the scope of achieving the object of the present invention. That is, the above embodiments should be considered as examples of all the points of the invention and not as limitations. In other words, the scope of the present invention is defined by the claims, not by the description of the above embodiments, and includes all modifications within the meaning and scope equivalent to the claims.

Industrial applicability of the invention

The invention provides a refrigerator with high reliability, which can be easily disassembled and assembled, and can firmly fix and hold a cover, thereby improving the maintainability of components and the like and ensuring the protection of a lead connector connecting part. Therefore, it is not necessary for home use, and it can be widely used for various purposes such as a commercial refrigerator and a display case.
