Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a refrigerated show case in which cooling air is forced to circulate along the inside of the transparent glass of the door body.

(Prior Art) As a conventional refrigerated case (including a frozen case), for example, one shown in FIG. 4 has been provided. The other side except the opening 1 formed in the front for storing and taking out products is surrounded by a heat insulating wall 2, and three door bodies 4 having transparent glass 3 are pivoted to the opening 1 so that they can be opened and closed. It is something. Reference numeral 5 denotes a handle attached to the door body 4 on the opposite side from the pivoting part.

FIG. 5 is a longitudinal cross-sectional view of the refrigerated case, with the portion excluding the door body 4 cut away, and schematically showing the internal structure thereof. Components that are the same as those shown in FIG. 4 are designated by the same reference numerals, and redundant explanation thereof will be omitted. Reference numeral 6 designates a plurality of shelf boards arranged in parallel on the support plate 7. An evaporator 8 of a cooling cycle system is provided at the bottom of the lowest shelf board 6, and an evaporator 8 of the cooling cycle system is provided between the heat insulating wall 2 and the support plate 7. A blower fan 10 is provided at the upper end of the created ventilation gap 9 to forcefully circulate the cooling air that has been heat exchanged in the evaporator 8 in the direction of arrow P. Further, at the upper front part of the heat insulating wall 2, there is an air outlet 11 that supplies the cooling air guided upward to the front part by the blower fan 10 to the lower front part, that is, to the lower part along the inner surface of the transparent glass 3 of the door body 4. A rectifier 12 is provided on the downstream side of the air outlet 11 to uniformly diffuse and rectify the cooling air on the inner surface of the door body 4. In such a refrigerated display case, the cooled air cooled by the evaporator 8 is forcedly circulated by the blower fan 10 to cool the displayed items on the shelves 6. Note that the air outlet 11 can be omitted if necessary.

In such a conventional refrigerated show case, the door body 4 is opened when the displayed items on the shelf board 6 are taken out, but at this time, the cooling air only flows directly down in the direction of the arrow in FIG. The cooling air does not come into contact with the inner surface of the transparent glass 3, and the outside air comes into contact with the inner surface of the transparent glass 3. At this time, since the inner surface of the transparent glass 3 is cold, the high temperature moisture contained in the outside air adheres to the inner surface and forms dew condensation, which causes the transparent glass 3 to fog up and close the door body 4. Immediately after the opening, there was a problem in that the items on display inside were no longer visible from the outside.

In order to solve these drawbacks of the conventional refrigerating case, a case disclosed in Japanese Utility Model Application No. 59-26578 (not shown) has been proposed.

This show case has two rectifiers in the front and back that rectify the cooling air, and the front rectifier guides the cooling air diagonally to the inner surface of the door made of transparent glass. .

According to this case, when the door body is opened, the cooling air blown from the front rectifier is blown onto the inner surface of the transparent glass, thereby preventing dew condensation on the inner surface of the door body.

(Problem that the invention seeks to solve) However, in the latter case, the inclination of the front rectifier is constant from the pivot point of the door body to the opposite side, so On the side (the part where the distance between the door body and the rectifier is short), there is a risk that the air will be blown toward the door body at a more acute angle than necessary. In such a case, the cooling air collides with the door body and returns to the rear side, and does not flow smoothly downward along the transparent glass, resulting in a situation where dew condensation on the lower part of the door body cannot be prevented. On the other hand, on the opposite side of this shaft support (the part where the distance between the door body and the rectifier is long), the blowing angle of the cooling air is too small and this cooling air does not reach the transparent glass, ensuring that dew condensation on the door body does not occur. The problem was that it could not be stopped.

(Purpose of the invention) The purpose of the invention is to prevent dew condensation on the entire door body by blowing cooling air at a desired deflection amount to each part of the inner surface of the door body while it is open. Our goal is to provide refrigerated cases that can

(Means for Solving the Problems) In order to achieve the above object, the present invention has a door body with a transparent glass that surrounds the other side with a heat insulating wall except for the openings formed on the front for storing and taking out products. The opening can be freely opened and closed by having one horizontal end pivoted on the periphery of the opening and pivoting in the horizontal direction, and cooling air that extends along the upper edge of the door above the inside of the door. In the refrigerated case, the cooling air is forced to circulate along the inside of the door body from the discharge part, and the cooling air discharge part has a cooling air discharge part extending from one lateral end of the door body to the other lateral end. A rectifying device that deflects the cooling air toward the opening direction of the door body and gradually increases the amount of deflection of the cooling air from one lateral end side to the other lateral end side of the door body. It is characterized by having been provided.

(Function) According to the present invention, when the door body is rotated in the horizontal direction to open the door body, one lateral end of the door body is pivoted, so one lateral end of the door body is pivoted. The distance between the other end in the lateral direction and the rectifier is greater than the distance between the other end and the rectifier.

Therefore, in consideration of this point, the rectifying device according to the present invention gradually increases the amount of deflection of the cooling air from one lateral end of the door toward the other lateral end. As a result, when the door is opened, the cooling air deflected by the rectifier is blown over the entire inner surface of the door, thereby preventing the entire transparent glass from fogging.

(Example) FIG. 1 is an enlarged perspective view of essential parts showing the principle of the present invention, and the same components as shown in FIG. In FIG. 1, reference numeral 13 denotes a flow straightening device, which is arranged at a lower discharge part of the cooling air outlet 11, and this discharge part extends along the upper end of the door body 4 above the inside of the door body 4. . The flow straightening device 13 includes a plurality of support rods 14 installed horizontally above the front part of the heat insulating wall 2, and a plurality of deflection blades 15 vertically supported by these support rods 14 and arranged in parallel in the horizontal direction. Become. All or part of these blades 15 are biased in the opening direction of the door body 4 as they move toward the handle 5 side of the door body 4, and their lower parts are biased in the opening direction of the door body 4 with respect to the upper part. ing.

Therefore, in this rectifying device 13, even when the door body 4 is opened, the cooling air from the outlet 11 is directed to the door body 4.
The amount of deflection is decreased near the shaft portion (one side in the lateral direction of the door body 4), and the amount of deflection is increased near the handle 5 (the other end side in the lateral direction of the door body 4), and each spray is applied to the inner surface of the transparent glass 3. It turns out. Figure 2 shows such a situation. Therefore, even after the door body 4 is opened, the inner surface of the transparent glass 3 continues to be cooled, and contact with the outside air is cut off, thereby preventing the transparent glass 3 from fogging due to dew condensation as in the conventional case. Thus, door body 4
Even immediately after closing, the displayed items can be clearly seen through the transparent glass 3.

FIG. 3 shows another rectifier 13A. This is a honeycomb-like structure formed into a rectangular prism shape, and as described above, the structure is moved from one end to the other so that cooling air hits the entire surface of the transparent glass 3 of the open door body 4. It is gradually being twisted. In such a honeycomb type flow straightening device 13A, by arbitrarily selecting the amount of twist of this, the door body 4
The amount of cooling air deflected toward the inner surface of the transparent glass 3 can be optimally set according to the size and degree of opening.

(Effects of the invention) As explained above, according to the invention, since the amount of deflection of cooling air corresponds to the distance between the door body and the rectifier, when the door body is opened, the amount of deflection of the cooling air by the rectifier is Cooling air is blown over the entire inner surface of the door body, which has the advantage of reliably preventing fogging of the entire transparent glass.
