Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an open show case that uniformly cools the inside of the product storage case.

(Prior Art) Conventionally, as shown in FIG.
A predetermined distance between the case body 1, which has a heat insulating material 1c filled between it and an outer box 1b covering the outside of the case body 1 and a product outlet 1d on the top surface, and the front wall 11, bottom wall 12, and back wall 13 of the case body 1. An evaporator 4 and a blower 5 are arranged in the space 2, and an air outlet 21 is provided at the upper end of the back wall 13 side of the space 2. An open show case is known in which an intake port 22 is provided at the upper end of the front wall 11 side of the spacer 2.

According to this open show case, when the blower 5 is driven, the air in the spacer 2 is turned into cold air through the evaporator 4 and blown out from the outlet 21 toward the intake port 22, as shown by the dashed-dotted line arrow in the figure. , an air curtain is formed between the product storage case 3 and the product takeout port 1d. Further, a part of the cold air flows into the product storage case 3 to cool the product. Furthermore,
The air that has flowed into the suction port 22 flows into the gap 2 and is cooled again in the evaporator 4.
constitutes the cold air circulation path of the open show case.

(Problems to be Solved by the Invention) In the conventional open show case, cold air is blown from the back wall 13 side of the show case body 1 toward the front wall 11 side. Due to the viscosity of the cold air, the internal resistance of the side wall 14, etc., the flow velocity of the cold air flowing along the side wall 14 becomes slower than the center side of the case body 1, and the amount of cold air circulated also decreases. This results in
The cold air blown out from the air outlet 21 reaches the volume side wall 14.
There was a problem in that the product did not flow sufficiently to the front side of the product storage case 3 nearer to the product storage case 3, and the product stored in this area could not be sufficiently cooled.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to provide an open show case that can sufficiently cool both front sides of the product storage case.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a case body which has a heat insulating material filled between an inner box and an outer box that covers the outside of the inner box, and has a product outlet on the top surface. , a product storage case disposed within the case body at a predetermined distance from the front wall, bottom wall, and back wall of the case body, and having both sides closed by the side walls of the case body; In addition to arranging an evaporator and a blower, an outlet is provided at the upper end of the back wall side of the gap, and an inlet is provided at the upper end of the front wall of the gap, and the gap is connected from the outlet to the suction port. In an open show case configured as a cold air circulation path for blown cold air, a cold air inlet is provided on both side walls of the show case main body near the front side of the product storage case, and a cold air inlet is provided in the upper part of the inner box on each side wall. A cold air outlet is provided in the lower part of the inner box of each side wall and faces the space, and a cold air bypass path is provided which communicates the cold air inlet and the cold air outlet.

(Function) According to the present invention, by driving the blower, the air in the chamber is cooled through the evaporator, and is blown out as cold air from the outlet to the upper part of the product storage case. A part of this blown cold air circulates inside the product storage case, another part is sucked into the suction port, and still another part is sucked into the cold air inlet. Here, the cold air inlet is formed near the front side of the product storage case on both side walls of the case body.
The cold air from the outlet is forcibly circulated to the front portions on both sides of the product storage case, and the cold air is sufficiently circulated to these portions as well.

(Embodiment) FIGS. 1 and 3 show an open show case according to the present invention, and the same components as those of the conventional example are denoted by the same reference numerals. That is, 1 is a case body with a product outlet 1d extending from the center of the top surface to the front side, and a heat insulating material 1c is filled between an inner box 1a and an outer box 1b that covers the outside of the inner box 1a. It is something. Reference numeral 3 denotes a product storage case, which is arranged at a predetermined distance 2 from the front wall 11, bottom wall 12, and back wall 13 of the case body 1, and whose both sides are closed by both side walls 14 of the case body 1. There is. In addition, an air outlet 21 is provided at the upper end of the back wall 13 side of the gap 2, and an inlet port 22 is provided at the upper end of the front wall 11 side. A blower 5 is installed at each of the air blowers 5, and the air blower 5 between them constitutes a cold air circulation path for circulating cold air as shown by the dashed line arrow in the figure.

Reference numeral 6 denotes a cold air bypass passage, which is formed by cutting out a part of the heat insulating material 1c vertically in each side wall 14 of the case body 1, as shown in FIG.
It is provided on each side wall 14 closer to the front side of the product storage case 3. Reference numeral 61 denotes a cold air inlet communicating with the upper end of the cold air bypass passage 6, and is constituted by a large number of slits formed in the inner box 1a of each side wall 14. 62
A cold air outlet communicating with the lower end of the cold air bypass passage 6 is formed in a horizontal rectangular shape at the lower end side of the inner box 1a of each side wall 14, and faces the bottom wall 12 of the spacer 2.

Note that 7 is a see-through glass provided at the upper end of the front wall 11 of the case body 1, and 8 is a fan casing of the blower 5.

According to this embodiment, by driving the blower 5, the air in the space 2 is blown out through the evaporator 4 from the outlet 21 toward the inlet 22, as shown by the dashed-dotted line arrow in the figure. . A part of this blown cold air circulates within the product storage case 3 and is used to cool the products in the product storage case 3. Further, another part of this cold air flows into the suction port 22 and forms an air curtain between the product storage case 3 and the product take-out port 1d, thereby preventing outside air from entering. Further, another part of the cold air is sucked into the cold air inlet 6a, passes through the cold air bypass passage 6, and circulates into the space 2 from the cold air outlet 6b. Here, since the cold air inlet 6a is provided closer to the front side of the product storage case 3 on both side walls 14 of the case body 1, a portion of the cold air from the outlet 21 is forced to the front side of both sides of the product storage case 3. The cold air that is not sucked into the cold air inlet 6a in the blown cold air flows to both sides of the product storage case 3 to cool the products stored in this part.

(Effects of the invention) As explained above, according to the invention, a portion of the cold air blown out from the outlet is forcibly sucked into the cold air inlet provided on the front side of both sides of the product storage case. This has the advantage that a sufficient amount of cold air flows through the front portions on both sides, and the products stored in these portions can be sufficiently cooled.
