  On the other hand, in the showcase section 30, the remaining portion of the cold air generated by the cooler 55 passes through the blowout path 65 as shown by the solid line in FIG. 2, and in detail, as shown by the solid arrow in FIG. After the cool air flows into the bat 80 from the through-hole 82 of the rear plate 81, the direction is changed upward and rectified through the rectifying member 110 in the blowout duct 90, and then the opening 102 and the blowout on the upper surface of the blowout duct 90 are blown. It blows out from the exit 94. The blown-out cold air is circulated and supplied so that it rises immediately after the slide door 34 as shown by the solid line in FIG. Thus, the food displayed in the storage room 40 is stored in a cooled state.

  In the showcase section 30, food and the like are taken in and out while opening and closing the slide door 34. Depending on the type of food, for example, if it is like a cake, food waste comes out and enters the outlet 65 There is a risk of depression. Specifically, although it falls through the flow regulating member 110 from the opening on the upper surface of the blowout duct 90 (the blowout opening 94 and the opening 102), the food waste that has fallen is a bat 80 disposed below the blowout duct 90. Received and accumulated. Therefore, it can be prevented that the cooler chamber 60 or the drawer portion 20 side is blown into the drawer portion main body 21 through the blower outlet 57.

  Garbage such as food waste stored in the bat 80 is discarded at an appropriate timing. In that case, the operation of the refrigerator is stopped, the slide door 34 is removed, and the front opening 33 of the showcase 30 is opened (state shown in FIGS. 3 and 10). From such a state, a hand is inserted through the front opening 33, and the upper end protruding from the guide wall 37 in the flange 93 of the duct body 91 and the upper end protruding from the partition wall 45 of the rear plate 95 are grasped and pulled up. Then, as shown in FIG. 9, the blowout duct 90 is removed from the upper end portion of the blowout path 65, and then is taken out of the warehouse through the front opening 33.

  Next, as shown in FIG. 9, by putting a hand into the blowout path 65 whose upper side is emptied and pulling up the bat 80 while holding the handle 86, the bat 80 is blown out as shown in FIG. 8. Since it is removed above 65, it is continuously taken out through the front opening 33. Thereafter, the dust collected in the bat 80 at an appropriate disposal location is discarded, and the bat 80 is washed with water as necessary.

  When washing the blowout duct 90 previously taken out with water, the rectifying member 110 is removed from the holder 100 by grasping and pulling the end of the rectifying member 110 protruding from the front and rear, so that the duct main body 91 ( (Including the holder 100) and the rectifying member 110 can be carefully washed with water individually.

  When the bat 80 and the blowing duct 90 are washed with water and dried, the rectifying member 110 is fitted into the holder 100 and attached to the blowing duct 90. Then, as described above, the bat 80 is inserted into the lower end portion of the blowout passage 65 and supported by being suspended, and then the blowout duct 90 is fitted into the upper end portion of the blowout passage 65 so that the blowout duct 90 and the bat 80 Are attached in a stacked manner, and after the sliding door 34 is fitted, the operation of the refrigerator may be resumed.

According to this embodiment, the following numerous effects can be obtained.
In the present embodiment, in the showcase section 30, a blowout path having a substantially L shape with an upper surface opening from the outlet of the cooler chamber 60 to the storage chamber 40 immediately after the front opening 33 in the bottom wall 42 of the case body 31. 65 is formed, whereas a bat having a box shape with an open top surface, which forms a cold air passage bent 90 degrees, that is, the cold air introduced from the cooler chamber 60 is directed upward at the corner of the outlet passage 65. 80, so that even if garbage such as food waste has fallen into the blowout passage 65, all the garbage is received on the bottom surface of the bat 80, the cooler chamber 60, It is reliably prevented from falling on the lower drawer section 20.

It is necessary to dispose of the dust collected in the bat 80 as appropriate in order to keep the inside of the blowing path 65 clean. Here, the structure of the portion where the bat 80 is interposed in the blowout path 65 suspends and supports the bat 80 on the lower side of the blowout path 65, while the blowout duct 90 is fitted and closed on the upper side of the blowout path 65. It has become. When throwing away the trash, the blowout duct 90 is pulled out and removed, and then the bat 80 is lifted and taken out and discarded outside the warehouse. As a result, garbage disposal can be easily performed.
In particular, since the blow-out path 65 is provided immediately after the front opening 33, the bat 80 can be easily taken out from the blow-out path 65 and further out to the outside. Further, the lower surface 63 of the partition plate 62 exposed after removing the bat 80 can be easily wiped and cleaned.

  A through hole 82 is opened in the rear plate 81 of the bat 80 so as to introduce cooling from the cooler chamber 60, but the area where the through hole 82 is formed is a predetermined dimension higher than the inner bottom surface of the bat 80. Limited to area. Therefore, even when cold air is introduced from the through hole 82 in a state where dust is collected on the bottom surface of the bat 80, the dust is not rolled up due to the cold air. Further, when the bat 80 is taken out from the blowing path 65 in order to throw away the garbage, the accumulated dust is prevented from falling into the blowing path 65 from the through hole 82.

  The blowout duct 90 contributes to blowing the cool air vigorously and straightly by mounting the flow regulating member 110 made of a honeycomb structure, but there is also a concern that dust is likely to be clogged because of the honeycomb structure. On the other hand, in this embodiment, since the rectifying member 110 is detachably attached to the duct body 91, the rectifying member 110 can be cleaned with water by removing the rectifying member 110 from the duct body 91. Further, since the rectifying member 110 is mounted by being fitted into the holder 100 provided in the duct main body 91 using its own elasticity, the rectifying member 110 itself can be easily attached and detached.
