Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a showcase provided with a transparent door.

(B) Conventional technology In the showcase described in Japanese Utility Model Publication No. 51-47236,
A showcase body provided with a cooler in the storage chamber, an opening / closing door provided at a front opening of the showcase body, and a warming provided on an outer surface of the opening / closing door provided at an upper edge of the front opening of the showcase body. A hot air outlet for ejecting wind and a hot air outlet that can be opened and closed freely.When the opening / closing door is closed, the warm air is ejected to the outside surface of the opening / closing door, and when the opening / closing door is opened, the warm air is opened. Is shown, and a damper for preventing the entry into the storage chamber is provided, and the hot air prevents the outer side surface, which is the surface of the opening / closing door, from fogging and dew condensation.

(C) Problems to be Solved by the Invention According to the above-described conventional technique, the hot air blown from the jet outlet along the surface of the opening / closing door has the left and right side portions of the outside air in a substantially stationary state immediately after the jet ( Due to the involvement of (air in the store), the speed gradually slows down compared to the central part and it spreads in the direction of the outside air. As a result, warm air flows along the lower left and right sides of the surface of the opening and closing door away from the jet outlet. There was a problem that it did not flow and fogging and dew condensation occurred on the part.

The present invention is intended to solve such problems.

(D) Means for Solving the Problems In order to solve the above problems, the present invention provides a showcase in which a dew-proof airflow is made to flow along the surface of a transparent door that opens and closes an opening. A means is provided in which a slender guide is provided on at least one side of the transparent door that is parallel to the flow direction of the air flow, and a side portion of the air flow is in contact with the elongated guide.

(E) Action According to the above means, the guide of the transparent door moves straight along with the action of preventing the warm air blown out from the warm air passage and flowing along the surface of the transparent door in the lateral direction on both the left and right sides. Imparts sex.

(F) Example An example of the present invention will be described below with reference to the drawings.
(1) is a showcase in which a main body is composed of a heat insulating wall (2) having openings on both front and left and right sides, and rails (3) and (4) forming a pair of upper and lower rails are provided on the front opening. Left and right guided transparent doors (5) and (6) are provided, and transparent side plates (7) and (8) are provided at the left and right side openings, and the inside (9) together with the heat insulation wall (2). ) Is formed. Reference numeral (10) is a partition plate which is arranged at an appropriate distance from the inner surface of the heat insulating wall (2) and divides the inside (9) into two, and a storage room (12) provided with a plurality of shelves (11). ) And cooler (13)
And a blower fan (14), one end of which is an air outlet (15) located in the upper front part of the inside (9) and the other end of which is a suction port (16) located in the lower front part of the inside (9). Cold air passages (17)
Are formed, and the cool air that has undergone heat exchange in the cooler (13) is forcedly circulated in the chamber (9) by the blower fan (14) as indicated by the solid arrow in FIG. Cool storage items by forming a cold air curtain (AC) on the front.

(20) is a machine room formed below the heat insulation wall (2), and constitutes a cooling cycle with the cooler (13), a refrigerant compressor (21), a condenser (22) and a blower fan (23). Are stored. A front panel (25) having a large number of elongated intake passages (24) is detachably provided on the front surface of the machine room (20), and a cover plate (26) forming a warm air passage described later is provided on the rear surface. Has been. The cover plate (26) is arranged at an appropriate distance from the outer surface of the heat insulating wall (2), and a warm air passage (27) which also serves as an exhaust passage of the machine room (20) is formed due to this arrangement. To be done. The inlet (28) of the warm air passage (27) faces the machine room (20), and the outlet (29) is located above the transparent doors (5) and (6).

Reference numeral (30) is a decorative panel arranged at a distance from the outer surface of the front wall (2A) of the heat insulating wall (2) to serve as a return path (31) for warm air, and the space below the decorative panel is the kicking space. (32)

Outside air (air in the store) is introduced into the machine room (20) through the intake passage (24), and this outside air becomes warm air (H) accompanying cooling of the condenser (22) and the compressor (21). 2 is blown out from the outlet (29) through the warm air passage (27), flows along the surface of the transparent doors (5) and (6), and then passes through the return passage (31) to the intake passage (24). The circulation indicated by the chain line arrow is repeated to prevent fogging and dew condensation on the surfaces of the transparent doors (5) and (6).

As another embodiment, the warm air passage (30) may be formed separately from the machine room (20) as shown in FIG. 4 and provided with a blower fan (34) for guiding the outside air. .

The transparent doors (5) and (6) are composed of a rectangular transparent plate (40) made of glass and an annular frame (41) surrounding the peripheral edge of the transparent plate, and are blown out from the outlet (29). An elongated guide (42) also serving as a handle is provided on one side of the frame (41) parallel to the flow direction of warm air so as to project forward. This guide (42) is provided on the left side of the frame (41) for the transparent door (5) that moves to the right, and on the right side of the frame (41) for the transparent door (6) that moves to the left. It is preferable that the height is equal to the height of the transparent doors (5) and (6), but it is slightly shorter due to the opening / closing operation. Further, the guide (42) is formed with an inclined side (43) slightly inclined inward.

Therefore, the guides (42) of both the transparent doors (5) and (6) are blown out from the warm air passageway (30) and beside the left and right sides of the warm air (H) flowing along the surfaces of the both transparent doors (5) and (6). In addition to having the effect of preventing diffusion in the direction, it imparts straightness.

FIG. 5 shows another embodiment of the present invention. In such an embodiment, one transparent door (5) pivotably supported by a hinge (50) at the front opening of the showcase (1). Are provided, and guides (42) parallel to each other are provided on both left and right sides of the frame (41) of the transparent door (5), and warm air (H) is flown between the guides (42) so that the surface of the transparent door (5) is Prevent fogging and condensation. The guide on the left side of the both guides (42) acts as a handle.

(G) Effect of the Invention In the above-described present invention, the guide provided on the transparent door prevents lateral diffusion of the side portion of the dew-preventing airflow flowing along the surface of the transparent door to impart straightness. As a result, the air flow flows along the entire surface of the transparent door, and as a result, it is possible to prevent fogging and dew condensation on the surface of the transparent door.
