[0004]

However, the above-described conventional structure for mounting the wind guide nozzle assembly has the following problems in terms of maintainability. 1) When the showcase is installed at the location of the location and the dew prevention heater 10 incorporated in the wind guide nozzle assembly 9 has a problem and the heater needs to be replaced, the nozzle assembly 9 should be replaced with the case. It is necessary to temporarily remove the heater from the main body and replace the heater. In the conventional mounting structure shown in FIG. 6, the nozzle assembly 9 is fastened to the upper surface side of the ceiling panel 1d with the screw 15, so that the screw 15
In order to loosen the case body with a screwdriver, the canopy 6 (see FIG. 5) of the case body 1 closing the front and the honeycomb body arranged at the cool air outlet 8 of the outer layer air curtain are removed. Disassembly work is required.

[0005] 2) When showcases of the same model are connected left and right in a store at a location, and there is a misalignment in the connection seam of the air guide nozzle assembly 9 between adjacent showcases, the appearance is reduced. Since the appearance is impaired, the mounting position of the air guide nozzle assembly 9 is adjusted by moving the mounting position of the wind guide nozzle assembly 9 forward and backward or up and down according to the situation at the site when the showcase is installed. In the case of the conventional structure shown in (1), a large-scale disassembly operation of the case main body is required as in the above-mentioned item (1).

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to solve the above-mentioned problems, and to easily attach / detach a wind guide nozzle to / from a case body and adjust and move the attachment position with a simple operation. Accordingly, it is an object of the present invention to provide a cold air circulation type open showcase which has been improved as described above, and in particular, a mounting structure of a wind guide nozzle assembly incorporated in the case body.

[0007]

According to the present invention, in order to achieve the above object, according to the present invention, a partition is provided between a cool air outlet of an inner layer air curtain and a cool air outlet of an outer layer air curtain in a case body. In a cold air circulating showcase in which a wind guide nozzle assembly with a dew-proof heater is mounted at the front end of a partition ceiling panel, the nozzle assembly is detachably screwed to the lower surface of the panel via a fixing bracket connected to the back surface thereof. At the same time, a wind guide cover that also serves as a nozzle receiver that covers the upper end of the nozzle assembly and projects forward in an eave shape is provided on the upper surface side of the panel. Can be configured.

1) After inserting a cushioning heat-insulating sealing material into a gap between the front end surface of the partitioning ceiling panel and the wind guide nozzle assembly, the nozzle assembly is moved forward and backward through fixing brackets.
And it is mounted so that it can be adjusted vertically. 2) As a means for adjusting the movement of the air guide nozzle assembly in the above item 1), a long hole for front and rear and up and down screw fastening is opened in the fixing bracket, and a screw is passed through the long hole to fix the fixing bracket, the partition ceiling panel, and Fasten between the fixture and the nozzle assembly.

3) In the above item 2), the fixing bracket is divided into a panel mounting washer and a nozzle mounting washer, and the two washers are hinged to each other via a hinge. 4) The above-mentioned air guide cover is hinged to the front upper surface of the partition ceiling panel via a hinge. According to the above configuration, the wind guide nozzle assembly is screw-fastened to the lower surface side of the partition ceiling panel of the case main body via the fixing bracket coupled to the back side thereof, and the nozzle is attached to the upper wind guide cover. The assembly is simply snap-fitted and supported. Therefore, even when replacing the dew-proof heater incorporated in the wind guide nozzle after assembling the showcase, simply insert the hand into the cool air outlet of the inner layer air curtain from the inside of the refrigerator and loosen the screw, and the case body will be replaced. The nozzle can be easily removed from the case body without requiring extensive disassembly work (canopy disassembly). An eave-shaped wind guide cover that covers the upper end of the nozzle assembly prevents the laminar flow of the outer air curtain from being disturbed due to a step generated between the mounting base of the nozzle assembly and the ceiling panel. Acts as a guide.

[0010] Further, when a plurality of showcases are connected to the left and right and installed at the location, and the connection of the air guide nozzles is adjusted between adjacent showcases, the nozzles can be connected in the same manner as described above. The mounting position can be easily moved back and forth and up and down. In addition, by combining the fixing bracket with a hinge as in item 3), the inclination angle of the nozzle can be adjusted. In addition, as in item 4), the air guide cover is hinged to the upper surface of the ceiling panel via a hinge. By doing so, it is possible to follow the vertical movement adjustment of the nozzle assembly without replacing the wind guide cover.
