Description

The present invention relates to a forced convection type cooling showcase that blows and cools cold air into a product storage chamber, and more specifically, a cold air supply unit that supplies cold air. Regarding the improvement of the structure.

2. Description of the Related Art It is well known in the past to surround a portion for storing a product with a transparent body so that the product can be easily seen from the outside, and there are many proposals. In particular, a product in which the side of the product storage area is surrounded by four transparent glasses (this is called a four-sided glass type showcase) has been devised.
The publication 0-22301 is one such example.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Not only the above-mentioned publications but also show glass of a four-sided glass type have a space between the cooling chamber provided with the cooler and the blower, and the bottom plate for partitioning the storage chamber for storing the product. By forming an air outlet and a suction port at opposite positions, the storage chamber and the cooling chamber are communicated with each other, and a circulation path of cold air along each wall of the storage chamber is created, and the storage chamber is surrounded by this cold air. I was trying to do it. However, in order to improve the cooling circulation while ensuring the storage capacity of the storage room, it is common to form the air outlet and the air inlet so as to be separated from each other in the same horizontal plane. Because it does not take a configuration to flow between each other,
Immediate cooling of products located on the inner circumference was impossible compared to products located on the outer circumference.

Therefore, the present invention appropriately changes the positions of the blower outlet, the suction inlet, and the opening of the ventilation chamber disposed below the blower outlet so that the cool air passes through the commodities and flows from the blower outlet to the suction inlet. The challenge is to provide a showcase that

[Structure of Invention]

Means for Solving the Problems The cooling showcase of the present invention has a product storage room, which has a display base at the bottom, which is surrounded by a see-through member that is openably and closably held and on which a product is placed. It is equipped with a box in which a ventilation room for circulating cold air with the room is placed below the display stand.
The display stand has a recess on which a product is placed, a blowout port formed between the recesses, and a suction port formed on the outer periphery of the recess, and the ventilation chamber communicates with the blowout port through an opening. And the cool air return part communicating with the suction port are separated from each other, and the cool air supply part has a cool air inlet formed on one side from directly below the center position of the exhibition stand and an opening formed deviated to the other side. Is.

The opening as the cold air outlet in the cold air supply section of the ventilation chamber
Directly below the center of the exhibition stand (distance from the cold air inlet)
Since it is located on the other side, the cool air is blown more vigorously to the other side than the center of the lower surface of the display stand and the one side. Cold air is easily blown out from the positioned outlet. Also, since the opening is formed at a position away from the cold air inlet,
It is easy to make the thickness of the cold air supply unit small in the height direction.

It is a separate type showcase consisting of a pipe (4), and it can be used for freezing, refrigerating, ice temperature and warming by changing the temperature zone to be controlled according to the type of products to be stored. In the example, a refrigerated showcase will be described as an example.

The mechanical box (3) is adiabatically partitioned by styrene foam, etc., and is equipped with an evaporator and a first machine room for sending cooling air with an air blower for the evaporator, and a compressor and a rest of equipment such as a condenser. The second machine room is installed side by side, and the first machine room is provided with the cool air delivery part and the return cool air intake part side by side on one wall. One side surface is covered with both parts and the lower end part of the blower pipe is inserted. A receiving part (5) to be incorporated in such a manner is arranged. Further, on one side surface of the machine box (3), for example, on the side of the receiving section (5), operation knobs such as a power switch and a temperature control knob are centrally arranged at one location.

The display box (2) is mounted on the turntable (13) and the base (11) having the turntable (13) on which the sale product is placed and which is rotatably and detachably held It is composed of a transparent member (hereinafter referred to as a hood) (14) that defines a product storage chamber (12) above the base (11) so as to surround the product, and the display stand (G) or the like. It is to be placed on.

The base (11) has a substantially circular shape in a plan view and serves as a bottom wall of the product storage chamber (12). The ventilation chamber (15) is provided above and below the turntable (13).
, The lighting room (16) is formed in the lower stage, and both rooms (15) (1
6) is partitioned by a partition plate (17), a heat insulating material (18), and a translucent member having a heat insulating property, for example, three-layer transparent glass (19).

Further, the lighting room (16) is provided with a lighting lamp which is a part of the lighting device, for example, an annular fluorescent lamp (20) below the three-layer transparent glass (19), and the central space of the fluorescent lamp (20). Is used to arrange an electric component such as a glow lamp. Then, the power switch (20B) of the fluorescent lamp (20) is arranged at a proper place of the base (11), for example, beside the cover of the hinge device (21), and the heater is automatically energized at least when the fluorescent lamp is turned off. It is preferable that

On the other hand, the hood (14) surrounding the product storage chamber (12) has a plurality of transparent bodies having a three-dimensional shape of a lower surface opening, for example, a hemispherical shape, spaced from each other by a transparent resin such as an acrylic acid resin. The main body is configured by arranging in a plurality of layers (three layers in this example), and a fixing piece protruding outward from the lower part of the transparent body located in the outermost layer is fixed to the hinge device (21).
The spacing between the transparent bodies is selected within a range in which convection is less likely to occur in the air layer in the spacing portion (see JP-B-61-3201 for a covered transparent body formed in a flat plate shape). In this example, the thickness is about 5 mm, and the air layer itself is a kind of heat insulating layer.

Place a container (referred to as a beverage container) (23) containing products to be sold, such as a drug solution or a soft drink, on the turntable (13). In order to make it easier to check the state of being lined up from the outside, the height of the part that receives the bottom of the container is made higher toward the center so that it acts as a shelf.
That is, it is formed in a spherical surface in side view (specifically, a curved surface of a part of a sphere) so that it has a circular shape in plan view and is gradually lowered from the center to the periphery, and is rotated by the lower portion and the rotation assisting member (22). It is held freely movable and detachable. In addition, the recesses (24) having a shape (circle, rectangle, etc.) substantially matching the bottom shape of the product to be displayed are arranged in an orderly manner. As an example of this, as shown in FIG. 4, 24 circular recesses (25) are arranged side by side in an annular shape on the outside, and an inner circular recess (25B) is formed on the outer circular recess (25A). The height of the bottom surface is higher than that of), and ten square recesses (26) are formed inside. And 1. in the center of the bottom of the circular recess (25).
A small protrusion (25C) having a height of about 5 to 2.5 mm is formed, and the remaining portion where the recess (24) is not formed, for example, between the square recesses (26) or between the square recesses (26) and the inner side. The outlet (28) is formed between the circular recess (25B) and the shape and size and the number of arrangements, and the suction port (29) is formed on the outer periphery of the outer circular recess (25A). is doing. Furthermore, on the underside of the turntable (13),
A rotation groove (38) for holding the rotation assistance member (22) is formed in an annular shape.

Further, outside the suction port (29), a handle portion (30) that serves as a handle when rotating the turntable (13) is erected with a wall surface curved in the left-right direction, It can be used as a POP advertising department that exposes the name and price of displayed products, and the cold air blown into the product storage room (12) is directed downward and inward to hit the lower part of the hood (14). Prevent and prevent. The handle portion (30) may be formed over the entire circumference of the turntable (13), but in this example, the handle portion (30) is formed.
(30) Stand on the front side of the display box (2) (the side facing the hinge device (21)) and the back side (the side of the hinge device (21)) in a symmetrical shape with an arc of 90 °. In addition, the number of suction ports (29A) located inside the handle part (30) is larger than that of the suction ports (29B) of other members to increase the opening area. The cold air that is taken in is sucked in more from the suction port (29A) inside the handle part (30), and even if there is no handle part (30), the cold air hits the bottom of the hood (14) less. it can.

On the other hand, explaining one example of the ventilation chamber (15), the ventilation chamber (15) partitions the lower surface of the turntable (13) located at the bottom of the product storage chamber (12) from the partition plate (17) and the high and low pressure space. Partition member (3
1), the partition member (31) is a blower pipe (4) on one side.
Cold air inlet to take in cold air carried from the machine box (3) at
(32) has a cold air supply part (34) which has a cylindrical shape when viewed from the top and has openings (33) as cold air exits formed on the upper surface (see FIG. 1), and around the side wall of the cold air supply part (34) Is the cold air return section (35). Here, the cold air introduced from the cold air inlet (32) is guided toward the opening (33), but if the opening is formed so as to match directly below the central portion of the turntable (13),
The blowout port (28) formed in the central portion of the turntable (13) is blown out more than the other blowout ports (28), so that it easily hits the zenith portion of the hood (14) and fogging easily occurs in this portion. Further, the blown-out cool air is drawn by the return cold air outlet (not shown) provided in parallel with the cold air inlet (32), so that it becomes difficult to reach the other side from the center of the turntable (13). However, a cold part and a non-cool part are formed in the product storage chamber (12), which causes a problem that the temperature distribution in the cold store becomes uneven. Therefore, the openings (33) are formed by biasing the cool air inlets (32) toward one side to one side from directly below the center position of the turntable (13). That is, in this example, as shown in FIG. 1, the turntable on the upper surface of the cool air supply unit (34) is
A circular opening (33) is formed with its center located on the other side of the position directly below the center of (13). The opening (33) is not limited to the circular shape and may be a rectangular shape or an elliptical shape.

Here, the cold air directed upward in the blower pipe (4) is directed horizontally in the cold air supply unit (34) and again directed upward in the opening (33). Turntable (1
By forming the opening (33) by biasing the cold air inlet (32) to one side from directly below the center position of (3), the turntable (1
It is possible to blow out more from the air outlet (28) of 3) from the peripheral portion (particularly on the other side away from the cold air inlet (32)) than from the central portion, and it is directed diagonally upward instead of directly above All of the air can be blown out, the amount of air blown onto the top of the hood is reduced, and the inside of the storage chamber (12) can be cooled uniformly.

The cold air supply part (34) is formed with an annular step (36) so that the turntable (13) can be positioned in correspondence with the annular standing wall (37) formed on the lower surface of the turntable (13). In addition, when this positioning is done, a closed space is formed between the lower surface of the turntable (13) and the opening (33) so that the cool air discharged from the opening (33) is stored. A short cycle of cold air returning to the cold air return section (35) without being blown out to the room (12) is prevented.

〔The invention's effect〕

As described in detail above, according to the present invention, the opening serving as the cool air outlet in the cool air supply portion of the ventilation chamber is located on the other side from directly below the center position of the display stand, and the one side cool air inlet is located. The cold air blown out from the outlet of the exhibition stand can be directed obliquely upward with a gentle inclination, and the cool air emitted from the outlet on the other side compared to the cool air emitted from the outlet in the center and one side. The amount of cold air can be increased, and the cold air can be prevented from hitting the see-through member, especially the zenith, and the occurrence of fogging can be reduced. Moreover, since the cold air inlet and the opening are not close to each other, it is possible to flatten the cold air supply part,
The flatness of the ventilation chamber itself can be promoted.
