Thus, refrigerator 10 is configured to allow air to flow between inside large freezer compartment 16 and inside small freezer compartment 15 .

However, if such a gap exists, there is a concern that the items stored in the small freezer compartment 15 may fall into the large freezer compartment 16 through the gap. Therefore, as exemplified in FIG. 7, the horizontal partition member 200 is provided with a gap filling portion 290 for filling this gap. In this case, the gap filling portion 290 is integrated with the rear portion of the right end portion of the lateral partition member 200, in other words, the rear portion of the right end portion of the small freezer compartment bottom surface forming portion 202 as viewed from the front side of the heat insulating box body 11. is provided in Moreover, the gap filling portion 290 has a structure having a plurality of through holes 291, that is, a so-called mesh structure.

In particular, in this embodiment, the holding piece 121 is provided at the upper front portion of the upper and lower partition member 100 . Therefore, a worker positioned on the front side of the heat insulation box 11 can easily perform the task of hooking the sensor-side wiring 112 on the holding piece 121 . Also, the operator positioned on the front side of the insulation box 11 can easily connect the connector 115 of the sensor-side wiring 112 and the connector 131 of the insulation box-side wiring 130 .

In addition, even when the upper and lower partition member 100 is installed between the ice making compartment 14 and the small freezer compartment 15, the operator positioned on the front side of the heat insulation box 11 can operate the sensor from the front side of the heat insulation box 11. The work of hooking the side wiring 112 to the holding piece 121 and the work of connecting the connector 115 of the sensor side wiring 112 and the connector 131 of the insulation box side wiring 130 can be easily performed. That is, the operator can more easily and smoothly perform the work of hooking the sensor-side wiring 112 to the holding piece 121 and the work of connecting the connector 115 of the sensor-side wiring 112 and the connector 131 of the heat insulating box-side wiring 130. can be done.

According to this configuration example, the sensor-side wiring 112 can be accommodated in the lower end portion of the upper and lower partition member 100 without protruding downward. Therefore, the sensor-side wiring 112 is caught between the lower end surface of the vertical partition member 100 and the upper surface of the horizontal partition member 200. In other words, the lower end portion of the vertical partition member 100 is lifted from the upper surface of the horizontal partition member 200. You can avoid getting lost. Moreover, it is possible to prevent the sensor-side wiring 112 from protruding into the ice making compartment 14 or the small freezer compartment 15 .

In addition, by avoiding the lower end of the upper and lower partition member 100 from rising from the upper surface of the horizontal partition member 200, air circulation between the inside of the ice making compartment 14 and the inside of the small freezer compartment 15, in other words, cool air, is prevented. can be suppressed, and the inside of the ice making compartment 14 and the inside of the small freezer compartment 15 can be maintained at their respective preset temperatures.

Here, assuming a case where the horizontal partition member 200 is attached from above the attachment position, in the structural example of the refrigerator 10 according to the present embodiment, the vertical partition member 100 is attached above the attachment position of the horizontal partition member 200. In front of the vertical partition member 100, a support member 280, refrigerant pipes (not shown), and the like are arranged. In other words, since many parts are arranged above the mounting position of the horizontal partition member 200, the structure is also complicated. Therefore, when attempting to attach the horizontal partition member 200 to the attachment position from above, the task is difficult.

According to the refrigerator 10 according to this embodiment, the horizontal partition member 200 is attached from the lower side, which is the large freezer compartment 16 side. Therefore, unlike the case where the horizontal partition member 200 is attached from the upper side, the attachment work can be easily performed without being affected by other components almost or completely.

In addition, in a general refrigerator, the opening area of the front opening of the storage compartment provided below is larger than the opening area of the front opening of the ice making compartment and the opening area of the front opening of the small freezer compartment. formed large. Therefore, according to the refrigerator 10 of the present embodiment, the horizontal partition member 200 can be attached through the front opening of the large freezer compartment 16 having an opening area relatively larger than that of the ice making compartment 14 and the small freezer compartment 15 . , the horizontal partition member 200 can be attached more easily.

Further, according to the refrigerator 10 , the screw fixing portion 260 is provided for permanently fixing the horizontal partition member 200 temporarily fixed by the elastic piece portion 240 and the claw-like portion 250 using the screw 400 . According to this configuration example, first, the horizontal partition member 200 is temporarily fixed at a predetermined position in the heat insulating box body 11, in this case, at a height position between the ice making compartment 14, the small freezer compartment 15, and the large freezer compartment 16. In this state, the horizontal partition member 200 can be permanently fixed. As a result, the horizontal partition member 200 can be more accurately attached to a predetermined attachment position within the heat insulating box 11 .

Furthermore, according to the refrigerator 10 , the screws 400 are obliquely attached to the temporarily fixed lateral partition member 200 from the upper front portion of the heat insulating box body 11 toward the lower rear portion. According to this configuration example, the worker who manufactures the refrigerator 10 can easily insert the screw 400 from the upper front part of the heat insulating box body 11 toward the lower rear part, and can easily perform the work of finally fixing the horizontal partition member 200 . be able to.
