Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a cold air forced circulation type electric refrigerator, and more particularly to improvement of a discharge side portion of a cold air duct.

[Conventional example]

In the cold air forced circulation type electric refrigerator, the cold air generated by the evaporator is guided to the refrigerating room or the vegetable storage room by the blower fan through the cool air duct. FIG. 2 shows a structure for introducing cold air from the cold air duct into the vegetable storage compartment.

That is, conventionally, when introducing cool air into the vegetable storage chamber 1, a hole is formed in the inner box 2, the discharge end 3a of the cool air duct 3 is inserted into the hole, and the polystyrene foam is provided on the wall surface on the vegetable storage chamber 1 side. The nozzle 4 made of, for example, is arranged, and the nozzle 4 is covered with the decorative cover 5. In this structure, the cool air from the cool air duct 3 spreads in the nozzle 4 and is discharged toward the inside of the vegetable storage chamber 1 through the blowout holes 6 formed in the nozzle 4.

[Problems to be solved by the device]

However, in the above-mentioned conventional structure, since the decorative cover 5 is required in addition to the nozzle 4, the cost is added accordingly, and it is necessary to screw the decorative cover 5 and seal the periphery thereof firmly. There are drawbacks, such as having to do it.

[Means for Solving the Problems]

In order to solve the above conventional problems, in the present invention,
At the discharge side end of the cold air duct 3, a nozzle 10 made of styrofoam resin integrally having a cold air blowout hole 11 is attached, and the nozzle 10 is attached to the inner box 2 of the food storage chamber 1.
A recess 12 conforming to the shape of FIG. 2 is formed, the nozzle 10 is placed in the recess 12, and the nozzle 10 is attached to the inner box 2 with a heat insulating material 8 foamed between the inner box 2 and the outer box 7. The feature is that it is fixed.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. In the figure, the same or like parts as those in FIG. 2 described above are designated by the same reference numerals, and the description thereof will be omitted.

According to this invention, the nozzle arranged on the back side of the inner box 2
Equipped with 10. The nozzle 10 is integrally formed of styrofoam resin, the discharge end portion 3a of the cool air duct 3 is connected to the upper portion thereof, and the cool air blowing hole 11 is formed in the lower portion thereof.

In relation to the nozzle 10, the inner box 2 is provided with a recess 12 into which the nozzle 10 is fitted, and a through hole 13 corresponding to the cold air blow hole 11 is provided at a predetermined portion of the recess 12. Has been formed.

In the above structure, the nozzle 10 is arranged in the recess 12 in a state where the cool air duct 3 is connected to the nozzle 10, and urethane foam or the like is injected between the inner box 2 and the outer box 7 to form the heat insulating material 8. Form. At this time, the nozzle 10 is firmly fixed to the inner box 2 by the heat insulating material 8.

[Effect of device]

As described above, according to this invention, a decorative cover is not particularly required unlike the conventional case. Further, since the nozzle 10 is fitted and arranged in the concave portion 12 of the inner box 2 and finally fixed to the inner box 2 by the heat insulating material 8, there is no need for screwing or the like, and there is no variation in the mounting work, and the quality is high. Is stable and the work man-hours can be reduced.

[Brief description of drawings]

FIG. 1 is a sectional view showing an essential part of an embodiment of the present invention, and FIG. 2 is a sectional view similar to FIG. 1 showing a conventional example. In the figure, 1 is a vegetable storage room, 2 is an inner box, 3 is a cold air duct, and 10
Is a nozzle, 11 is a cool air blowing hole, and 12 is a recess.

Claims (1)

[Scope of utility model registration request] 1. Forced circulation of cold air, which is produced by an evaporator, is guided to a predetermined food storage chamber 1 by a blowing means through a cold air duct 3 inserted between an inner box 2 and an outer box 7. In an electric refrigerator of the type, a nozzle 10 made of styrofoam resin having a cold air blowout hole 11 is attached to the discharge side end of the cold air duct 3, and the shape of the nozzle 10 is provided in the inner box 2 of the food storage chamber 1. To form a recess 12 that matches
An electric refrigerator characterized in that the nozzle 10 is arranged in the recess 12 and the nozzle 10 is fixed to the inner box 2 by a heat insulating material 8 foamed between the inner box 2 and the outer box 7.
