Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a low-temperature showcase in which storage chambers are formed in two levels, upper and lower, and the upper opening of the lower storage chamber is appropriately covered with a roll-up cover. The main purpose is to properly handle dew from the upper cooler and cuff S-.

The embodiment of the present invention will be explained below with reference to the drawings. (1) is v
A low-temperature showcase whose main body is made up of a heat insulating wall (2) that opens the JIII to a large extent. (2B), a top wall (2C), a bottom wall (2D) whose tip protrudes forward from the top wall, and a transparent plate on the top (2G)
(2G) on both the left and right @11 (2K) (2E), respectively, and a partition ml (2F ) and is composed of Eri. (31 is an upper storage room with 18141 and a fluorescent light (5) inside, and the opening (6) for entering and exiting products at the front is closed with two transparent doors (7) that can be opened and closed.
This storage room is located at an appropriate distance from the upper part of the back wall (2B), the inner surface of the ceiling wall (2C), and the upper surface of the partition wall (2F).
By arranging a removable bottom plate (9), a cold air passage αI and both outlet and suction ports α1lQ3 facing each other are formed along both upper and lower inner edges of the opening.

A plate fin type cooler (13) is installed at the bottom of the cold air passage.
) and an axial flow blower I located on the windward side of this cooler are installed, and the cold air that has been heat exchanged in the cooler (131) is forcedly circulated by the blower I as shown by the arrow to create a transparent air blower (7). Air courtesy (C
A1) to cool the upper storage chamber (3). (15
1 is a lower storage chamber which has an opening αe for entering and exiting goods on the upper surface, and this storage chamber has a front wall (2A), a bottom wall (2D), and a back wall (
2B) Transparent plate (17) and paper board QI3 that are removable at an appropriate interval from the inner surface of the lower part and the bottom of the partition wall (2F) [i]
1. By arranging the partition plate 0 and the group of wind direction plates, a cold air passage Qυ is formed along with both the outlet and suction ports @(c) facing each other along both front and rear edges of the upper surface opening. A plate fin type cooler (2) and a trickle type blower located on the lee side of this cooler are installed at the back of the cold air passage shaft υ, and the flow air that has been heat exchanged by the cooler (2) is The lower storage chamber (C) is cooled by forming an air curtain (CA2) that closes the area opening (161) through forced circulation as shown by the arrow with the blower (C).
3 is an air curtain (CA2) that closes the opening αe.
A rectifying device (A) made of cross-section honeycomb material is provided with a gradient that slows down the speed from the inside to the outside. (5)
is a fluorescent light installed at the front of the bottom of the partition wall (2F).
The lower storage chamber (15) is illuminated through the 161.
0A) (30A) is provided with a removable cover plate...
Inside is the meat compressor for the upper storage room and the lower storage room, between the condensers that liquefy the high-temperature waste refrigerant from this surface compressor, the blower, the electrical equipment box (toward), and a part of the top surface. A drain tank with a flow channel (filter 6A) that can be taken out and put in freely (
) has been installed.

C71 is 1W (DI) of cooler 031 in the upper cold air passage ■
with the drain pipe that guides it to the back right corner of the upper cold air passage υ.
It is arranged so that it passes straight through the bottom of the partition wall (2F) and further through the rear part of the wind direction plate (2) so that its lower end faces the back right corner of the lower cold air passage Cυ. (to) is lower cold air passage <217
This is a drain pipe that guides the dew (D2) of the cooler (24) to the drain tank (to) at the end of the machine room. Waterway (36A)
It is arranged to face the The perforated airflow direction plate is made of a metal plate, and as shown in FIG. 6, the front edge and left and right side edges are bent upward at right angles so that 11 (D5) from the cover, which will be described later, drips into the lower storage chamber 051. The vertical upper part (2

A guide hole (31) with a large and shallow diameter is formed on the outside diameter of the drain pipe for passing through. It is attached to a cylindrical core material (41) with an automatic return function, and the other end is attached to an η-y shoe (4) with a U-shaped stopper (44) (44) is a pivot member installed on both sides of the upper surface of the wind direction plate (■), which pivots both ends of the core member and holds the stone (411) so that it can be wound freely.mj
When the store is open, the cover will be used as a wind direction board as shown in Figure 2.
It is stored in a cylindrical shape at the top, and when the store is not open, for example at night, it can be extended, and by locking its stopper (43) to the hook (44) at the lower front of the main body, the lower storage compartment 09
This is intended to reduce the refrigeration load by covering the upper surface opening 0e and the front wall (2A). The gD6 that adheres to the top surface of this cover when it is used in extension is removed from the guide hole 3I through the guide hole 3I when the cover is rolled up and stored. ) as well as the lower cold aisle (

ejected into a column.

In addition, the butterflies attached to the lower surface of the partition wall (2F) are also dripped onto the wind direction plate l and treated in the same way as the storm on the cover (g).

According to this configuration, the wind direction plate (a) is a single (: air outlet Q2
The guide member of the drain pipe G7) not only serves to guide the flow of cool air from the upper cooler 0 to the upper surface opening 0e of the lower storage chamber, but also guides the dew from the upper cooler 0 to the lower cold air passage Cυ, and the supporting member of the cover frame. The structure of the upper part of the back of the cold air passage αυ is simple, and the dew that has adhered to the bottom and partition wall (2F) soil surface of the cover (41) is dripped into the lower storage chamber (151). Since the cold air is guided from the guide hole OI to the cold passage Cυ without causing any dew, dew treatment becomes very good.
