A cover plate 8 made of stainless steel or the like is attached to cover the. The contact plate 8 has a flat plate shape, and its outer edge is inserted and engaged in an inward groove 9 formed on the front side 3A of the storage frame 3 on the outside of the storage section 12. On the other hand, at the front end of the inner side 3B of the storage frame 3, there is formed a holding piece 10 which is rotatable by a hinge portion 6 made of soft vinyl chloride as shown in FIG. The protrusion 11 formed on the inner surface is engageable with and disengageable from the engagement recess 5 formed on the inner side 3B. Then, this protrusion 11 is shown in FIGS.
The holding piece 10 is engaged with the engaging plate 5 as shown in FIG.
The front side of the inner edge of is pressed to fix the contact plate 8 to the storage frame 3.

As described above, the opening frame 3 is formed by extrusion molding of the hard resin, and the plurality of hollow chambers 50 and the heater holding portion 7 are formed.
Since the housing portion 12 is formed, the material cost can be remarkably reduced as compared with the conventional case, and at the same time as the extrusion molding, the overheat preventive device OH or the lead wire can be formed without performing the counterboring process or the like unlike the conventional case. It is possible to configure the storage unit 12 that stores L.

The heater holding portion 7 holds the heater H in a state where the heater H is exposed on the front surface side (gasket 41 side), and the housing portion 12 is opened to the front surface side, and
Since the heater holding portion 7 and the storage portion 12 are covered with the contact plate 8 that is detachably provided on the storage frame 3 so as to face the gasket 41, the heater H, the overheat protector OH, and the lead wire L are forward. Can be attached to the heater holding portion 7 and the storage portion 12. Therefore, the assembling workability is improved, and also when the heater L is replaced, the storage frame 3 is attached to the side plate panel 1.
There is no need to remove it from the machine, and maintenance workability is significantly improved.

In particular, the groove 9 into which one end (outer edge) of the contact plate 8 is inserted and engaged with the storage frame 3, and the other end of the contact plate 8 which is rotatable with respect to the storage frame 3 (inner side). Holding piece 10 for holding the edge)
Since it is formed, it is not necessary to fix the contact plate with a screw as in the prior art, and the workability of attaching the contact plate 8 is significantly improved.
In addition, the lead wire L has a lead-out hole 20 formed at an appropriate position as shown in FIG.
Through to the outside.

The side plate panel 1 is a steel plate facing material 1 for inside and outside.

The screws 4 and 4 for fixing the storage frame 3 to the side plate panel 1 avoid the spacer 18 and pass through both sides of the spacer 18, and the flanges 1 of the face materials 13 and 14 of the side plate panel 1 are passed.
3A and 14A are screwed together. Here, if the compartment frame 3 is fixed at the central portion of the trim 16 as shown in FIG. 9, the through hole 200 must be formed in the spacer 18 as shown in FIG. It becomes unnecessary. Further, it is not necessary to align the holes for inserting the screws 201 into the through holes 200. Further, the spacer 18 has an engaging rib 19
Since it is engaged with and fixed to the storage frame 3, the special component for fixing the spacer 18 to the storage frame 3 or an adhesive agent is not required, and the manufacturing cost is reduced. Further, since the storage frame 3 is fixed to the flanges 13A and 14A on both sides of the spacer 18, the fixing strength is also improved as compared with the case of FIG.

Reference numeral 22 is a door for closing the opening 2 so as to be openable and closable, and is pivotally supported by hinges 23, 23 on the front side 3A on one side of the storage frame 3. Each of the doors 22 has a metal outer plate 24 and an inner plate 26, and both plates 2
The ends of 4 and 26 are engaged with both ends and fixed with screws 27, so that the trim 28 made of hard synthetic resin connecting them and the space formed by the outer plate 24, the inner plate 26 and the trim 28 The heat insulating material 29 is foam-filled.

A groove 32 that opens to the rear surface (the surface facing the side plate panel 1) is formed in the central fixing portion 31 of the trim 28, and this groove 32 can be opened and closed by a rotatable lid portion 33. Has been done. Further, the tip of the lid 33 is spaced from the fixed portion 31 in the closed state. On the other hand, 4
Reference numeral 1 denotes the magnet gasket mentioned above, which holds the gasket 41 by inserting the edging portion into the groove 32 and closing the lid portion 33 in this state. When the door 22 is closed, the gasket 41 comes into contact with and comes into close contact with the contact plate 8.

A latch 48 having a coil spring (not shown) inside and a latch claw portion 46 and a handle 47 is attached to the front surface of the door 22 on the non-pivot side. Further, the latch 48 is opposed to the latch 48. A latch receiver 52 is attached via a latch receiver 53 to a side surface 54 of the front side 3A of the storage frame 3 at the position (on the non-pivotal side of the door 22).
The latch receiver 52 includes a roller 49, and the latch claw portion 46 engages with the roller 49 to keep the door 22 closed. Reference numeral 62 denotes a handle for releasing the engagement between the latch receiver 52 and the latch 48 from the inside of the refrigerator.

Next, FIGS. 11 to 14 show another embodiment of the present invention. In this case, an outward groove 61 is formed at the front end portion of the inner side 3B of the storage frame 3, and the inner edge of the contact plate 8 is inserted and engaged in the groove 61. On the other hand, on the outer side of the storage portion 12 at the front side 3A of the storage frame 3, a hinged piece 62 made of soft vinyl chloride is formed with a rotatable holding piece 63 as shown in FIGS. 63 makes the protrusion 64 formed on the inner surface thereof engageable with and disengageable from the engagement recess 65 formed on the front side 3A. Then, with the projection 64 engaged with the engagement recess 65 as shown in FIGS.
The front side of the outer edge of is held and the contact plate 8 is fixed to the storage frame 3.

In the structure shown in FIG. 7, since the holding pieces 10 rotate in the direction of the opening 2, adjacent holding pieces 10 interfere with each other at the corners of the storage frame 3. Therefore, it is necessary to delete the holding piece 10 and insert another corner piece in the corner portion of the storage frame 3 within a predetermined range, but in the configuration of FIGS. 11 to 14, the holding piece 63 is not the storage frame. Since it pivots to the outside of 3, there is no interference at the corners, and there is no need to remove it and attach a corner piece or the like.

[0034]

As described in detail above, according to the first aspect of the invention, the opening frame is formed by extrusion molding of the hard resin, and the plurality of hollow chambers and the heater holding portion at the position facing the gasket are provided. Since the housing portion is formed in the vicinity of the heater holding portion, the material cost can be remarkably reduced as compared with the conventional case, and the overheat preventive device can be formed simultaneously with the extrusion molding without performing the counterboring process as in the conventional case. It is possible to configure a storage unit that stores the lead wire and the like.

In particular, according to the invention of claim 2, in addition to the above, the heater holding portion holds the heater in a state where the heater is exposed on the gasket side, and the housing portion is opened to the gasket side, and the gasket is Since the heater holding part and the storage part are covered with a metal contact plate that is detachably attached to the storage opening frame facing the heater, the heater, the overheat protector, and the lead wire are installed from the front to the heater holding part and the storage part. It becomes possible to attach it to the section. Therefore, assembling workability is improved and
