The cooler 42 is connected to a compressor, a radiator and an expansion mechanism (not shown) by a refrigerant pipe to form a refrigerating cycle in which the refrigerant is circulated. The compressor compresses the refrigerant, and the radiator condenses the refrigerant compressed by the compressor to dissipate heat. The expansion mechanism adiabatically expands the refrigerant radiated by the radiator to bring it into a low temperature and low pressure state.

In the above showcase, the air inside the storage chamber 12 is sucked through the suction port 13 by driving the fan 41, and the sucked air is sent out to the air outlet 14 through the air passage 20 through the air outlet 14. By blowing air into the storage chamber 12, air is circulated between the storage chamber 12 and the air passage 20.

The cooler 42 exchanges heat between the air passing through the back duct 22 from the lower side to the upper side by driving the fan 41 and the refrigerant which has been made into a low temperature and low pressure state by the expansion mechanism. The air passing through the back duct 22 is cooled by evaporating the low-temperature low-pressure refrigerant. The refrigerant evaporated in the cooler 42 is sucked into the compressor and circulates in the refrigeration cycle.

The intermediate duct 50 has a substantially flat plate shape as a whole. The intermediate duct 50 is detachably attached to the storage chamber 12 in such a manner that the rear end portion blocks the back duct 22 through the through hole 16 of the back panel 15 constituting the back surface of the storage chamber 12. ..

Here, in the present embodiment, the through hole 16 of the back panel 15 is the lower part of the product display shelf 30 in the second stage from the top, the lower part of the product display shelf 30 in the third stage from the top, and the fourth stage from the top. It is provided at the bottom of the product display shelf 30 and at the bottom of the bottom product display shelf 30.

Then, as shown in FIGS. 1 to 3, the intermediate duct 50 penetrates the through hole 16 at the lower part of the product display shelf 30 at the third stage from the top, and the rear end is the back duct 22 (air passage 20). Is attached to the storage chamber 12 in a manner of blocking the air.

Such an intermediate duct 50 is provided with a wind tunnel 50a inside. The wind tunnel 50a extends along the front-rear direction and communicates with the introduction port 51 provided at the rear end and the intermediate air outlet 52 provided at the front end. The introduction port 51 opens downward and is an opening for introducing air passing through the back duct 22. The intermediate air outlet 52 is open downward and is an opening for blowing out air passing through the wind tunnel 50a.

Next, the product display shelf 30 will be described. As described above, a plurality (five) product display shelves 30 are provided, and the uppermost shelf and the second shelf from the top are installed above the intermediate height level of the storage chamber 12 and above. Those in the third and lower stages are arranged below the intermediate height level. Each of these product display shelves 30 includes a shelf board 31 and a slit forming member 32.

The shelf board 31 is a flat plate-shaped member, and is erected on a pair of left and right bracket members 33. The upper surface of the shelf board 31 constitutes a mounting surface on which products are placed, and the products are placed and displayed on the upper surface of the shelf board 31.

The slit forming member 32 is attached to the front end portion of the shelf board 31 to form the front end portion of the product display shelf 30. In the slit forming member 32, a plurality of rectangular elongated hole-shaped slits 32a having a longitudinal direction in the left-right direction are formed along the left-right direction. These slits 32a are for passing air blown out from the air outlet 14 or the intermediate air outlet 52 toward the suction port 13.

Then, in the product display shelf 30 of the third stage or lower from the top, that is, the slit forming member 32 of the product display shelf 30 arranged below the intermediate height level of the storage chamber 12, a resistance member is formed in the central region in the left-right direction. 32b is provided.

The resistance member 32b is provided between the slits 32a in the central region in the left-right direction, and more specifically, the resistance member 32b is provided in the central region so as to eliminate the slit 32a. The resistance member 32b is a member that acts as a resistance by blocking the air that is blown out from the air outlet 14 or the intermediate air outlet 52 and passes through the suction port 13.

Here, the central region in the left-right direction is a region of 1/3 or less, more preferably 1/5 or less of the length of the front end portion of the product display shelf 30 in the left-right direction. That is, the central region in the left-right direction is an region that is equal to or less than the left-right width of the central portion when the front end portion of the product display shelf 30 is divided into three equal parts in the left-right direction, and more preferably, the front end portion of the product display shelf 30 is used. This is an area that is equal to or less than the left-right width of the central portion when divided into five equal parts in the left-right direction.

In the showcase having the above configuration, the air inside the storage chamber 12 circulates as follows by driving the compressor and the fan 41.

The air inside the storage chamber 12 sucked into the lower duct 21 of the air passage 20 through the suction port 13 passes through the lower duct 21 and then the back duct 22.

The air passing through the rear duct 22 is cooled by the cooler 42. The air cooled by the cooler 42 is introduced into the wind tunnel 50a through the introduction port 51, passes through the wind tunnel 50a, and is blown out through the intermediate air outlet 52. The air blown out from the intermediate outlet 52 passes through the slit 32a at the front end of the product display shelf 30 and is sucked into the air passage 20 from the suction port 13 to circulate between the storage chamber 12 and the air passage 20. .. As a result, an air curtain with air cooled by the cooler 42 is formed on the front surface of the lower region of the intermediate duct 50 in the storage chamber 12.

In this way, the air (cold air) blown out from the intermediate outlet 52 forms an air curtain in front of the lower region of the intermediate duct 50. Therefore, the lower region of the intermediate duct 50 in the storage chamber 12 is the lower region of the intermediate duct 50. It can be cooled more than the upper area. As a result, the upper region and the lower region of the intermediate duct 50 in the storage chamber 12 can be set to different temperature zones, and the products in the storage chamber 12 can be held at two temperatures.

By the way, in the above showcase, in the product display shelf 30 arranged below the intermediate height level of the storage chamber 12, the resistance member 32b is provided in the central region in the left-right direction of the front end portion thereof, so that the center thereof. In the region, as shown in FIG. 3, the air blown out from the intermediate outlet 52 passes downward on the front side of the slit forming member 32. As a result, the pressure in the storage chamber 12 becomes smaller than the pressure outside the case body 10, so that it is possible to prevent the air curtain from being curved and disturbed toward the inside of the storage chamber 12.

As described above, according to the showcase according to the embodiment of the present invention, in the central region in the left-right direction in the front end portion of the product display shelf 30 arranged below the intermediate height level of the storage chamber 12. Since the resistance member 32b that blocks the air passing toward the suction port 13 and acts as a resistance to the air is provided, it is possible to prevent the air curtain formed by the air blown out from the intermediate outlet 52 from being disturbed. This makes it possible to prevent deterioration of the cooling performance of the product.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made.

In the above-described embodiment, the showcase to which the intermediate duct 50 is mounted has been described, but in the present invention, the intermediate duct may not be mounted. Even in this case, it is possible to prevent the air curtain from being disturbed by the air blown out from the air outlet, and it is possible to prevent a decrease in the ability to adjust the product to a desired temperature.

In the above-described embodiment, the resistance member 32b is provided at the front end portion of all the product display shelves 30 arranged below the intermediate height level of the storage chamber 12, but in the present invention, the storage chamber A resistor member may be provided on any of the merchandise display shelves located below the intermediate height level. Further, when the intermediate duct is attached, it is preferable that the resistance member is provided at the front end portion of all the product display shelves arranged below the intermediate duct.

In the above-described embodiment, the resistance member 32b is provided so as to eliminate the slit 32a, but in the present invention, the resistance member may be provided by closing a part of the slit. Further, since the resistance member may have a hole having a small diameter formed in the resistance member as long as the resistance of air passing through the slit is larger than that of the slit, the resistance member may be formed so as to project forward.
