On the rear surface of the inner box 4, a partition portion 4a forming a heat insulating partition wall 12 described later protrudes toward the front opening of the inner box 4. The partition portion 4a is open at the left, right, and rear surfaces of the inner box 4, and communicates with a heat insulating space formed between the outer box 3 and the inner box 4 through the opening.

A heat insulating material 5 such as a foam heat insulating material such as urethane foam or a vacuum heat insulating panel is provided in a heat insulating space formed between the outer box 3 and the inner box 4. A heat insulating material 5 such as a foamed heat insulating material is also provided inside the partition portion 4a forming the heat insulating partition wall 12.

A plurality of storage chambers are provided inside the inner box 4. Specifically, a refrigerating chamber 6 and a vegetable chamber 7 are provided in this order from the upper stage, an ice making chamber and a first freezing chamber 9 are provided below the chambers in a left-right arrangement, and a second freezing chamber 10 is provided below the chambers.

Both the refrigerating chamber 6 and the vegetable chamber 7 are storage chambers cooled to a refrigerating temperature range (for example, 1 to 4 ℃), and are partitioned in the vertical direction by a partition plate 11 made of synthetic resin.

The lower part of the vegetable compartment 7 is partitioned by a heat insulating partition wall 12 having a heat insulating material 5 provided therein, and a freezing space cooled to a freezing temperature zone (for example, -10 to-20 ℃) is formed. The freezing space is partitioned vertically by a partition plate 13, the upper space is further partitioned horizontally by a partition plate not shown, and an ice making compartment and a first freezing compartment 9 are provided, and a second freezing compartment 10 is provided below the partition plate 13.

The rear portions of the refrigerating chamber 6 and the vegetable chamber 7 are provided with: a refrigerating cooler chamber 22 defined by the evaporator case 20 and the rear surface of the inner box 4 in the front-rear direction, and a duct 23 connecting the refrigerating cooler chamber 22 and the refrigerating chamber. The refrigeration cooler chamber 22 houses a refrigeration cooler 24, a refrigeration fan 26, and the like.

Formed at the rear of the ice making compartment, the first freezing compartment 9 and the second freezing compartment 10 are: a freezer-cooler chamber 32 defined by the evaporator case 30 and the back surface of the inner box 4 in the front-rear direction, and a duct 33 connecting the ice-making chamber, the first freezer compartment 9, and the second freezer compartment 10 to the freezer-cooler chamber 32. The freezer cooler chamber 32 houses a freezer cooler 34, a freezer fan 36, a defrost heater 38, a drain tank 37, and the like.

The refrigerating cooler 24 and the freezing cooler 34 constitute a refrigeration cycle together with a compressor 42 and a condenser (not shown) housed in the machine room 40. In the refrigeration cycle, the refrigerant discharged from the compressor 42 is supplied to one of the cold storage cooler 24 and the freezer cooler 34 through a switching valve, not shown, and the cold storage cooler 24 and the freezer cooler 34 are cooled to predetermined temperatures.

The refrigerated cooler 24 cools the air in the refrigerated cooler chamber 22 to generate cold air at, for example, -10 to-20 ℃. The cold air generated in cold storage cooler compartment 22 is supplied to cold storage compartment 6 and vegetable compartment 7 by the rotation of cold storage fan 26, whereby cold storage compartment 6 and vegetable compartment 7 are cooled so that the temperature detected by temperature sensor 14 provided in cold storage compartment 6 reaches a predetermined temperature.

The freezer cooler 34 cools the air in the freezer cooler chamber 32 to generate cold air at-20 to-30 ℃, for example. The generated cold air is supplied to the ice making compartment, the first freezing compartment 9, and the second freezing compartment 10 through the duct by the rotation of the freezing fan 36, whereby the ice making compartment, the first freezing compartment 9, and the second freezing compartment 10 are cooled so that the temperature detected by the temperature sensor 15 provided in the second freezing compartment 10 reaches a predetermined temperature.

A defrosting heater 38 and a drain tank 37 are provided below the freezer cooler 34, and by energizing the defrosting heater 38 at a predetermined timing, the freezer cooler 34 is heated to melt and remove adhered frost. At this time, the defrosted water thus thawed is discharged from the drain tank 37 to the evaporation pan provided in the machine room 40.

The temperature sensor 15, the freezing fan 36, and the defrosting heater 38 are electric components provided inside the inner box 4. These

electric components

15, 36, and 38 are connected to a lead 44 extending from a control board 43 provided outside the refrigerator main body 2 through an insulated space of the inner box 4 in a connection portion 50 provided in the freezer cooler chamber 32, and a driving power source and a control signal are transmitted from the control board 43.

(2) Structure of connecting part 50

As shown in fig. 2 to 4, the connection portion 50 includes: a first connector 51 and a first housing 53 fixed to the inside of the inner box 4, a second connector 52 connected to the first connector 51, and a second housing 54 covering the first connector 51 and the second connector 52 together with the first housing 53.

The connection portion 50 is provided, for example, on the lower surface of the heat insulating partition wall 12 in the vicinity of the freezer cooler 34, and is located close to one side in the refrigerator width direction (in the present embodiment, the left side of the refrigerator as viewed from the front).

The first connector 51 is a female-side connector provided at the tip of the lead wire 44 connected to the control board 43, and is inserted through a through hole 4b provided in the partition portion 4a of the inner box 4 constituting the lower surface of the heat insulating partition wall 12 such that an insertion port into which the second connector 52 is inserted protrudes from the inner box 4 toward the inside of the box.

The first connector 51 includes a substantially rectangular parallelepiped housing 51a and terminals, not shown, electrically connected to the leads 44.

The housing 51a has a panel lock structure provided on the opposite side surfaces. As shown in fig. 3, the panel lock structure includes: a pair of arm portions 51b extending in a direction away from the case 51a as the side from which the lead 44 is drawn out from the distal end of the case 51a (hereinafter, the side from which the lead 44 is drawn out in the case 51a may be referred to as a proximal end side, and the proximal end side end and the distal end side may be referred to as a proximal end and a proximal end); a box inner contact portion 51c provided at a base end portion of the arm portion 51 b; and a heat insulation side abutting portion 51d protruding from a side surface of the housing 51 a.

The arm portion 51b is provided to be elastically deformable in a direction in which the case inside abutting portion 51c is slightly separated from the side surface of the housing 51 a. In a state where the arm portions 51b are not subjected to an external force, the interval between the case inside abutting portions 51c provided on the pair of arm portions 51b is larger than the diameter of the through hole 4b of the inner case 4, and when the arm portions are deformed so as to approach the side surface of the outer case 51a, the case inside abutting portions 51c can be inserted into the through hole 4b of the inner case 4 together with the outer case 51 a.

The case inside contact portion 51c has an inclined surface 51f inclined so as to approach the case 51a toward the base end side.

The heat insulating side abutting portion 51d protrudes from the opposite side surfaces of the outer case 51a, and the interval between the distal ends of the heat insulating side abutting portion 51d is larger than the diameter of the through hole 4b of the inner case 4. The heat insulating side abutting portion 51d is provided at a position distant from the case inside abutting portion 51c so that the distance to the base end of the case inside abutting portion 51c is equal to the thickness of the partition portion 4a of the inner case 4.

Such a first connector 51 is inserted into the through hole 4b from the heat insulation space side of the inner box 4 while narrowing the interval between the pair of arm portions 51 b. As a result, as shown in fig. 3, the base end portion (tip end portion) of the tank inside abutting portion 51c abuts against the tank inside of the peripheral edge portion of the through hole 4b, the heat insulation side abutting portion 51d abuts against the heat insulation space side of the peripheral edge portion of the through hole 4b, the inner tank 4 is sandwiched between the tank inside abutting portion 51c and the heat insulation side abutting portion 51d, and the first connector 51 is fixed to the inner tank 4.

The second connector 52 is a connector provided on the male side of the tip of the lead 39, which integrally bundles the leads of the electric components such as the temperature sensor 15, the freezing fan 36, and the defrosting heater 38, and is constituted by a substantially rectangular parallelepiped case 52a and terminals not shown.

As shown in fig. 4, a locking claw 52b is provided on a side surface of the housing 52 a. When the second connector 52 is inserted deep into the first connector 51, the engagement claw 52b engages with an engagement projection 51e provided on the side surface of the housing 51a of the first connector 51, thereby preventing the second connector 52 from coming off.

The first housing 53 is formed of a box-like body made of flame-retardant plastic having an opening 53a at the lower portion, and has a mounting hole 53b in the bottom surface through which the first connector 51 protruding further toward the inside of the box than the inner box 4 is inserted. The mounting hole 53b is formed by a stepped hole having a larger diameter inside (lower side in fig. 3) the first housing 53 than outside (upper side in fig. 3) the first housing 53. The aperture of the mounting hole 53b is smaller than the interval between the case inside contact portions 51c in the state where the arm 51b is not subjected to an external force, and the arm 51b and the case inside contact portion 51c are inserted into the mounting hole 53b together with the housing 51a by narrowing the interval between the pair of arms 51 b.

A flange portion 53c extending outward is provided on the entire periphery of the peripheral edge portion of the opening portion 53a of the first housing 53.

The flange portion 53c provided on the opposite side surfaces of the first housing 53 is provided with a first engagement frame 53d on one side and a claw portion 53e on the other side. The first engagement frame 53d protrudes outward from the opening 53a along the flange portion 53c, and is provided with a fitting hole 53f (see fig. 5 and 6) in which the projecting piece 54d of the second housing 54 is inserted.

The claw portion 53e is provided with an inclined surface which protrudes outward of the opening portion 53a along the flange portion 53c and which faces inward of the opening portion 53a as going from the bottom surface side of the first case 53 toward the opening portion 53a side (as going downward in fig. 4).

In the first housing 53, the arm portion 51b and the case inside contact portion 51c are inserted into the mounting hole 53b provided in the bottom surface of the first housing 53 while the distance between the pair of arm portions 51b is narrowed, so that the inclined surface 51f of the case inside contact portion 51c contacts the inner peripheral surface of the mounting hole 53b, and the peripheral edge portion of the mounting hole 53b (the inner peripheral surface of the mounting hole 53 b) is sandwiched between the inclined surface 51f and the inner case 4. Thereby, the opening 53a of the first housing 53 is directed downward, and the first housing 53 is fixed around the first connector 51.

The second case 54 is formed of a box-like body made of flame retardant plastic having an opening 54a at the upper side, and openably closes the opening 53a of the first case 53. A lead insertion hole 54b through which the lead 39 connected to the second connector 52 is inserted is provided in a central portion of the bottom surface of the second housing 54. A fixing portion 54h having appropriate elasticity and water permeability such as a soft tape is provided between the lead insertion hole 54b and the lead 39. The fixing portion 54h discharges water generated in the second housing 54 to the outside, and fixes the lead 39 to the second housing 54 at the position of the lead insertion hole 54 b.

A flange portion 54c extending outward is provided on the entire periphery of the peripheral edge portion of the opening portion 54a of the second housing 54. The flange portion 54c is provided with a gasket 55 such as a rubber sheet on the surface (upper surface in fig. 3) of the first housing 53 facing the flange portion 53 c.

One of the flange portions 54c provided on the side surfaces of the second housing 54 facing each other is provided with a projecting piece 54d inserted into the fitting hole 53f of the first housing 53, and the other is provided with a second engagement frame 54e engaged with the claw portion 53e of the first housing 53.

The projecting piece 54d projects outward from the opening 54a along the flange portion 54c, and an engagement projection 54f that engages with the first engagement frame 53d of the first housing 53 is provided at the tip end portion thereof. The second engagement frame 54e protrudes in a direction substantially perpendicular to the flange portion 54c, and an engagement hole 54g into which the claw portion 53e of the first housing 53 is inserted is provided inside the second engagement frame.

With respect to the second housing 54, the engaging projection 54f of the projecting piece 54d is engaged with the first engaging frame 53d of the first housing 53, and the claw portion 53e of the first housing 53 is engaged with the second engaging frame 54 e. Thus, the flange portion 53c of the first housing 53 and the flange portion 54c of the second housing 54 are brought into contact with each other with the spacer 55 interposed therebetween, and the second housing 54 closes the opening portion 53a of the first housing 53 in a state where the first connector 51 and the second connector 52 are housed therein.

(3) Method for assembling connection part 50

Next, a method of assembling the connection portion 50 will be described.

First, the first connector 51 provided at the tip of the lead 44 is inserted through the through hole 4b of the inner case 4, and the first connector 51 is fixed to the inner case 4. The inner box 4 to which the first connector 51 is fixed is assembled to the outer box 3, and the heat insulating material 5 is provided in the heat insulating space, whereby the refrigerator main body 2 in which the arm portion 51b and the box inside abutting portion 51c of the first connector 51 protrude downward from the ceiling surface of the freezer-cooler chamber 32 is manufactured.

Next, the bottom surface of the first housing 53 is directed upward and the first housing 53 is moved upward, so that the arm portion 51b and the case inside abutting portion 51c of the first connector 51 are inserted into the mounting hole 53b, thereby surrounding the first connector 51 and fixing the first housing 53 to the inner case 4. At this time, the first housing 53 is fixed around the first connector 51 in such a manner that the claw portion 53e is positioned on the front side of the refrigerator and the tab 54d is positioned on the rear side of the refrigerator. Further, since the arm portion 51b extends in a direction away from the housing 51a as it goes toward the base end side of the housing 51a, if the first housing 53 is moved upward, the distance between the pair of arm portions 51b is narrowed, and the arm portion 51b and the box inside contact portion 51c can be easily inserted into the mounting hole 53 b.

Next, the lead 39, which is formed by bundling the leads of the electric components provided inside the inner box 4, is inserted into the lead insertion hole 54b from the outside of the second housing 54, and then the second connector 52 is attached to the end of the lead 39.

Next, as shown in fig. 5, the first connector 51 protruding from the inner box 4 is coupled to the second connector 52. After the gasket 55 is provided on the upper surface of the flange portion 54c, as shown in fig. 6, the projecting piece 54d of the second housing 54 is inserted into the fitting hole 53f of the first housing 53 from below, and the engaging projection 54f is engaged with the first engaging frame 53 d. Then, the second housing 54 is rotated about the first engagement frame 53d as a rotation axis to move the second engagement frame 54e of the second housing 54 upward, and the claw portion 53e of the first housing 53 is inserted into the engagement hole 54g to engage the claw portion 53e with the second engagement frame 54 e. Thus, the connection portion 50 configured to accommodate the first connector 51 and the second connector 52 in the internal space defined by the first housing 53 and the second housing 54 can be attached to the inner box 4.

(4) Effect

In the refrigerator 1 of the present embodiment, the first connector 51 and the second connector 52 can be housed in a space closed by the first case 53 and the second case 54. Therefore, the cold air can be prevented from directly contacting the first connector 51 and the second connector 52 to prevent condensation, and the first connector 51 and the second connector 52 can be prevented from being burned toward other components when abnormal heat generation occurs.

In the present embodiment, since the first connector 51 is fixed to the inner box 4, the connecting portion between the first connector 51 and the second connector 52 does not move during the transportation of the refrigerator, and does not contact the freezer cooler 34 or the like provided in the periphery.

In the present embodiment, since the lead insertion hole 54b is provided in the bottom surface of the second case 54, even if water (dew condensation water) is generated inside the first case 53 and the second case 54, the water can be discharged from the lead insertion hole 54b to the outside.

In the present embodiment, since the first housing 53 is held between the inside contact portion 51c of the first connector 51 and the inner box 4, the first housing 53 can be fixed to the inner box 4 by the panel lock structure of the first connector 51, which is fixed to the inner box 4, and the first housing 53 and the second housing 54 covering the first connector 51 and the second connector 52 can be fixed to the inner box 4 by a simple structure.

In the present embodiment, since the lead 39 inserted through the lead insertion hole 54b of the second housing 54 is fixed to the second housing 54 by the fixing portion 54h, even if a tensile force acts on the lead 39, the force is less likely to act on a connection portion between the lead 39 and the second connector 52, and the connection portion 50 is less likely to be broken.

In the present embodiment, since the first housing 53 is fixed around the first connector 51 so that the claw portion 53e is positioned on the front side of the refrigerator and the projecting piece 54d is positioned on the rear side of the refrigerator, the rotational shaft for rotating the second housing 54 with respect to the first housing 53 can be disposed on the rear side of the refrigerator, and the connecting portion 50 can be easily assembled.

(5) Modification example 1

Modification 1 of the above embodiment will be mainly described with reference to fig. 7, focusing on differences from the above embodiment. Note that the same components as those in the above embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

In the present modification, the second housing 54 is integrally coupled to the first housing 53 via a self-hinge portion 156 provided thinner than the

flange portions

54c, 53 c. Thereby, the second housing 54 rotates about the hinge portion 156 to open and close the opening 53a of the first housing 53.

In the refrigerator according to such a modification, the first case 53 and the second case 54 can be formed as one component, so that the assembly workability can be improved and the cost can be reduced.

(6) Modification 2

A modification 2 of the above embodiment will be mainly described with reference to fig. 8, focusing on differences from the above embodiment. Note that the same components as those in the above embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

In the above-described embodiment, the case where the lead insertion hole 54b through which the lead 39 is inserted is provided in the center portion of the bottom surface of the second case 54 has been described, but in the present modification, the lead insertion hole 254b is provided further outside in the refrigerator width direction than the center portion C in the refrigerator width direction of the second case 54.

That is, the connecting portion 50 is provided at a position closer to one side in the refrigerator width direction (left side in fig. 8 when the refrigerator is viewed from the front), and the lead insertion hole 254b is provided at one side in the refrigerator width direction than the center portion C of the second housing 54.

In such a modification, since the lead 39 can be drawn out from the connection portion 50 to the outside in the refrigerator width direction (i.e., the side wall side of the refrigerator main body 2), the lead 39 is less likely to interfere with equipment disposed in the refrigerator such as the freezer cooler 34, and the lead 39 can be easily wired.

In the present modification, as shown in fig. 8, the lead insertion hole 254b is provided in the bottom surface of the second case 54, but may be provided in the side surface of the second case 54.

(7) Other modifications

In the above embodiment, the connection portion 50 is provided on the lower surface of the heat insulating partition wall 12 constituting the ceiling surface of the freezer-cooler chamber 32, but the connection portion 50 may be provided at any position inside the inner box 4, such as the rear surface and the side surface of the inner box 4.

The embodiments of the present invention have been described above, but these embodiments are merely shown as examples and are not intended to limit the scope of the invention. These embodiments may be implemented in other various manners, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention.
