Are provided (FIG. 10). 10 is a cold air passage 7
And a fixing member 12 for attaching and fixing the cooler 10 and rotatably supporting the fan case 3. The fixing member 12 is disposed substantially horizontally and at a low temperature above the cool air passage 7. It is provided substantially over the entire width of the showcase 17 in the width direction.

By the way, in the case of the conventional fixed system in which the fan case is rotated for cleaning the product storage room, a plurality of fans and a fan motor are integrally provided in the fan case. Since the fan case is heavy, a large number of hinges for mounting and supporting the fan case so as to be rotatable vertically are required. Depending on the width of the fan case, the required number of hinges may range from two to as many as ten or more, and the hinges are structurally expensive.

In the case where a hinge is used, a state where the hinge is lifted with one hand (a state where the hinge is lifted as shown by a broken line in FIG. 11)
This is convenient because the cleaning with the other hand can be easily performed. However, when the blower breaks down, the following disadvantages are instead encountered. That is, since the blower is heavy and large, it is difficult to perform the removal work and the wiring process inside the showcase, and it is necessary to take out the entire fan case out of the low-temperature showcase and then replace the blower. Therefore, it is necessary to remove all the hinges from the fixing member, which requires a tool such as a screwdriver, and also requires a great deal of time and labor for repair work.

Further, the bottom part may be slightly expanded or dented compared to the shape of a predetermined heat insulating box at the time of foaming or after foaming. In such a case, the fixing member and the fan case are connected via a hinge. The lower part of the fan case and the bottom of the cool air passage cannot cope with each other, so that a gap remains, and a gap flows from the gap to the suction side of the blower. A so-called short cycle has occurred, and the smooth flow of cool air in the cool air passage has been hindered.

Next, a procedure for cleaning the bottom portion 29 in the low-temperature showcase 17 will be described with reference to FIGS. First, the bottom plate 14 of the product storage room 1 is removed. Thereafter, the user holds the fan case 3 and pivots it rearward as shown in FIG. Then, the fan case 3 is pulled up until a position where the hand can enter the bottom portion 29 is reached. At this time, the fan case 3 rotates while sliding on the fixing member 12. However, since the engaging portion 41 provided on the fan case 3 is engaged with the flange portion 35 of the locking member 34 fixed to the fixing member 12, it does not come off from the fixing member 12 up to a certain angle. . In this state, cleaning of the periphery including the cool air passage 7 of the bottom portion 29 and cleaning of the cooler 10 are performed.

Next, when the blowers 2 are out of order, as shown in FIGS. 5 and 6, the fan case 3 is pulled up to be substantially vertical, and the horizontal flange 39 of the fan case 3 is fixed. 12 and the U-shaped engaging portion 41 formed on the fan case 3 also comes off the flange 35 of the locking member 34, so that the entire fan case 3 is fixed to the fixing member 12 Can be removed without using tools such as a screwdriver. After this,
Take it out of the low temperature showcase 17 and blower 2
The repair work can be performed easily and in a short time by exchanging.

As shown in FIGS. 7 and 8, the bottom portion 29 may be slightly expanded or dented compared to the shape of a predetermined heat-insulating box at the time of foaming or after foaming. It will either rise or sink. In this case, in the conventional hinge fixing method as shown in FIG. 10, the fixing member 12 and the fan case 3 are attached via the hinge 4 so as not to be displaced from each other. Walls 3c, 3c
There was a case where a gap was formed between the lower portion of the cooling air passage 7 and the bottom portion 29 of the cold air passage 7. However, in this embodiment, since the vertical and vertical positions of the fan case 3 can be easily moved, the front wall and the left and right side walls 3c of the fan case 3 can be moved.
The fan case 3 is locked to the fixing member 12 in a state where there is no gap between the lower part of 3c and the bottom part 29 of the cool air passage 7. That is, since the fan case 3 moves up and down or back and forth in response to the deformation of the bottom portion 29, the lower portion of the front wall and the left and right side walls 3c, 3c of the fan case 3 and the bottom portion 29 do not adhere to each other.

Next, as shown in FIGS. 3 and 4, the fixing member 12 further has an inclined portion 33 extending to the horizontal portion 32, and the fan case 3 further comprises a horizontal flange 3.
9 and also has an inclined flange 40,
When the fan case 3 is removed to replace the blowers 2... And then is engaged with the fixing member 12 again, the rear upper end portion (the upright flange 38 and the horizontal flange 39) of the fan case 3 is fixed to the fixing member. The engagement with the fixing member 12 is easily performed by being guided by the inclined portions 33 of the twelve, and therefore, the fan case 3 can be easily restored to the original normal state.

Further, unlike the present embodiment, the fixing member 12
Has an inclined portion 33 extending from the upright portion 31, the horizontal portion 32, and the horizontal portion 32. Similarly, when the fan case 3 has only the inclined flange 40, the fan case 3 It is possible to eliminate the necessity of a hinge for rotating the. That is, the user holds the fan case 3 and rotates the fixing member 12 on which the upper end of the rear portion rests on the fulcrum. Then, the fan case 3 is pulled up until a position where the hand can enter the bottom portion 29 is reached. At this time, the fan case 3 rotates while sliding on the fixing member 12.
Then, in a state where the inclined portion 33 on the rear upper end of the fan case 3 is placed on the fixing member, cleaning of the periphery including the cool air passage 7 of the bottom portion 29 and cleaning of the cooler 10 are performed.

Further, even when the fan case 3 rises or sinks by that much when the bottom portion 29 is slightly expanded or recessed compared to the shape of the predetermined heat insulation box at the time of foaming or after foaming, the fan case 3 Can be easily moved, the fan case 3 is locked to the fixing member 12 in a state where there is no gap between the bottom wall 29 and the front wall and the lower left and right side walls 3c, 3c of the fan case 3. That is, since the fan case 3 moves up and down or back and forth in response to the deformation of the bottom portion 29, the lower portion of the front wall and the left and right side walls 3c, 3c of the fan case 3 and the bottom portion 29 do not adhere to each other. No longer occur.
Therefore, the so-called short cycle in which the cool air sucked in by the blowers 2... And once sent to the cooler 10 is returned to the suction side of the blowers 2. Cold air will flow smoothly inside.

In the above embodiment, the horizontal portion 32 of the fixing member 12 is described as being substantially horizontal. However, even if the horizontal portion 32 has a slight inclination, and similarly, the inclination angle of the inclined portion 33 is substantially vertical. The cleaning operation of the bottom 29 in the low-temperature showcase 17 can be easily performed by the same procedure as described above. And even if the horizontal flange 39 of the fan case 3 has an inclination, and the inclination angle of the inclination flange 40 is substantially vertical, the cleaning operation can be easily performed similarly.
