Because it is a thing, I will omit the explanation.

  FIG. 4 is a perspective view showing the front product placement shelf 40a, and FIG. 5 is a cross-sectional view schematically showing the front product placement shelf 40a as viewed from the front. The front product placement shelf 40a will be described with reference to FIGS. The front product placement shelf 40a illustrated here includes a shelf plate 41, duct plates 42a, 42b, and 42c, and a closing member 43.

  The shelf board 41 is a plate-like body made of a transparent resin material such as acrylic resin, and its upper surface constitutes a placement surface on which products are placed. The shelf board 41 is supported on the front surface of the ventilation path component 20 via a pair of left and right brackets 44a and 44b.

  In the pair of left and right brackets 44a and 44b, locking pieces (not shown) protruding rearward enter the locking holes 25 formed at both ends of the front surface of the ventilation path forming section 20 to configure the ventilation path. It is latched by the front surface of the part 20, and supports the lower surface of the shelf board 41 by this. Here, the shelf board 41 has a length in the left-right direction that is greater than the distance between the pair of left and right brackets 44a and 44b, and protrudes to the left and right from the brackets 44a and 44b.

  Each bracket 44a, 44b is formed with a vent hole 441, and further, a pair of upper and lower support pieces 442 projecting left and right.

  A plurality of (three in the illustrated example) duct plates 42a, 42b, and 42c are provided, and each is a plate-like body made of a transparent resin material such as acrylic resin, like the shelf board 41. .

  The central duct plate 42a is disposed opposite to the shelf plate 41 so that the left end is sandwiched between the support pieces 442 of the left bracket 44a and the right end is sandwiched between the support pieces 442 of the right bracket 44b. Yes. Further, the left duct plate 42b is opposed to the shelf plate 41 so that the right end portion is sandwiched between the support pieces 442 of the left bracket 44a. Further, the right duct plate 42c is disposed opposite to the shelf plate 41 so that the left end portion is sandwiched between the support pieces 442 of the right bracket 44b.

  Such duct plates 42 a, 42 b, 42 c constitute a shelf duct 45 that allows air blown from the corresponding hole 24 to the shelf plate 41 to pass through the vent hole 441. The central duct plate 42a is formed with a plurality of ventilation holes 421 over the entire area, and the left duct plate 42b and the right duct plate 42c are portions other than the central region, that is, the front end portion and the rear end portion. A plurality of ventilation holes 421 are formed at the left end and the right end.

  The closing member 43 is an elongate member formed of, for example, metal or the like, and closes the front end portion and the left and right end portions of the shelf duct 45 composed of the shelf plate 41 and the duct plates 42a, 42b, and 42c. Is provided. In such a closing member 43, a slit-shaped opening 431 is formed. The closing member 43 is provided in such a manner as to close the front end portion and the left and right end portions of the shelf duct 45, but since the slit-shaped opening 431 is formed, the shelf duct 45 is actually closed. Absent. However, since the opening area of the slit-like opening 431 is smaller than the opening area of the front end portion and the left and right side end portions of the shelf duct 45, the static pressure inside the shelf duct 45 can be increased.

  By the way, when the closing member 43 is removed from the shelf plate 41, the duct plates 42a, 42b, 42c are only supported so as to be sandwiched between the support pieces 442 of the brackets 44a, 44b. As shown, the duct plates 42a, 42b, 42c can be easily detached by sliding the duct plates 42a, 42b, 42c forward. That is, the duct plates 42a, 42b, and 42c are detachably disposed on the shelf plate 41.

  In the round-type open showcase having the above-described configuration, when the front circulation fan 32 and the compressor are driven, the products placed on the front product placement shelf 40a are cooled as follows.

  The air inside the storage chamber 11 is sucked through the front suction port 12 a and passes through the front lower duct 12. The air passing through the front lower duct 12 passes around the evaporator 35 and is cooled. The air cooled by the evaporator 35 passes through the front ventilation path 21, and part of the air is blown out forward from each hole 24, and part of the air passes through the front upper duct 13 and moves forward. It blows out from the blower outlet 13a.

  The air blown out from the front outlet 13a forms an air curtain by flowing toward the front inlet 12a. By forming the air curtain in this way, the internal air of the storage chamber 11 is cooled while suppressing the entry of heat from the outside.

  The air blown out from each hole 24 enters the shelf duct 45. Here, since the shelf duct 45 is allowed to pass through the vent holes 441 of the brackets 44a and 44b, the air that has entered the shelf duct 45 is not substantially interfered with the brackets 44a and 44b, and the vent holes 45a and 44b. It can flow through 441 to both the front left and right ends of the front product placement shelf 40a. Moreover, since the static pressure in the shelf duct 45 is increased by the closing member 43, the air flowing through the shelf duct 45 is blown out downward from the vent holes 441 formed in the duct plates 42a, 42b, 42c, Products placed on the product placement shelves 40a, 40b, and 40c immediately below can be cooled.

  As described above, according to the round type open showcase according to the embodiment of the present invention, the air blown out from the hole 24 of the ventilation path constituting unit 20 is extended to the front left and right ends of the front product placement shelf 40a. Since the air flowing through the shelf duct 45 can be blown out downward from the vent hole 441, the air is placed on the left and right ends of the shelf 41 of the product placement shelves 40a, 40b, and 40c. The placed product can be satisfactorily brought to a desired temperature state.

  According to the round type open showcase, since the slit-shaped opening 431 is formed in the closing member 43, by blowing a part of the air that has entered the shelf duct 45 from the slit-shaped opening 431, It is possible to suppress the occurrence of condensation on the surface of the closing member 43.

  According to the round type open showcase, since the shelf plate 41 and the duct plates 42a, 42b, and 42c are transparent plate-like bodies, the product placement is performed even from above the product placement shelves 40a, 40b, and 40c. The product placed under the shelves 40a, 40b, and 40c can be visually recognized.

  According to the round type open showcase, since the duct plates 42a, 42b, 42c are detachably disposed on the shelf plate 41, the duct plates 42a, 42b, 42c are detached from the shelf plate 41 for cleaning, etc. Can be easily performed.

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

  In the embodiment described above, the slit-shaped opening 431 is formed in the closing member 43. However, in the present invention, the slit-shaped opening may not be formed in the closing member.

  In the embodiment described above, the duct plate 42 is detachable from the shelf plate 41. However, in the present invention, the duct plate support structure is particularly limited as long as the duct plate can be detached from the shelf plate. It is not something.
