Abstract

PURPOSE:To prevent disturbance of circulation of chilled gas and to improve containing properties of food by disposing an indoor lamp on a decorative plate of a freezing chamber by using a recess space in a refrigerator in which the plate having a recess for forming a chilled gas passage is disposed on a front surface of a back partition plate for partitioning a cooler and the chamber. CONSTITUTION:When a compressor is operated, the air around a cooled cooler is blown by a chilled gas fan 2, and circulated in a passage formed of a back partition plate 3 and a decorative plate 4 of a freezing chamber. A turbulent flow preventive plate 5 is disposed on a front surface in which turbulent flow of the fan 2 is easily generated, propagation of vibration to the plate 4 due to the turbulent flow and air cutting sound are suppressed. A recess 4a is formed on the plate 4 in a hollow part in the front interior of the plate 5. In this case, an indoor lamp 6 is mounted in the recess 4a through a socket 6a. Thus, the lamp suppresses a protruding size of a cover 7 from the plate 4, and containing properties of food in the chamber and designing properties are improved.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention provides an interior light that is installed to improve the ease of putting in and taking out food by illuminating the inside of the refrigerator, which lights up when putting food in and out of the refrigerator. This invention relates to an interior light installation structure that can be installed without impairing storage space or performance.

0002

[Prior Art] Conventionally, this type of refrigerator has a structure in which a recess is provided in the insulation wall at the upper part of the ceiling of the freezer compartment and an internal light is attached to this part, as shown in FIG. , which was designed to be attached directly to the back wall of the refrigerator compartment.

[0003] A conventional example of this type is Utility Model Application Publication No. 54-1.
There is a publication No. 47857.

[Problems to be Solved by the Invention] In order to provide a concave part in the ceiling inner box and install an interior light as in the above-mentioned prior art,
In order to obtain a heat insulating effect as a heat insulating material, the a dimension of the heat insulating thickness cannot be made very small, so the lamp cover protrudes from the inner box surface, resulting in a problem in which food storage properties and design are degraded.

Furthermore, in the prior art, the only way to increase the recess dimension and prevent the lamp cover from protruding was to increase the insulation thickness b dimension of the entire inner box ceiling.

[0006]Furthermore, in a structure in which a recess is provided in the back decorative panel of the freezer compartment and an interior light is installed, the cold air discharged from the cold air blower fan forms the rear partition plate and the back decorative board by the recessed portion of the back decorative board. In addition to blocking the cold air ventilation path and reducing performance, there were the same problems as the conventional technology.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention utilizes the internal hollow space of the turbulence prevention plate installed on the back side of the freezer compartment to provide a recessed portion in the freezer compartment decorative panel. The protruding dimensions of the interior light have been minimized.

[0008]

[Operation] A recess is provided from the freezer compartment decorative board in the internal hollow conical space of the turbulence prevention plate installed on the back side of the freezer compartment, and an interior light is attached to the freezer compartment decorative board or the internal hollow conical space is directly installed. The interior light is attached to the turbulence prevention plate, and the protruding dimension of the lamp cover can be reduced accordingly.

[0009] Also, the cold air discharged to the front by the cold air blowing fan is blown into the refrigerator through a turbulence prevention plate that prevents turbulence and passes between the back partition plate that forms a cold air ventilation path and the decorative panel of the freezer compartment. The interior light installed in front of the flow prevention plate and the recessed part of the freezer compartment decorative panel can be provided without any adverse effects by circulating cold air between the rear partition plate and the freezer compartment decorative panel as in the past.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3.
Explain according to the following. FIG. 1 is a longitudinal sectional view of a freezing chamber, FIG. 2 is a sectional view of a main part, and FIG. 3 shows a different embodiment of the present invention.

First, a description will be given with reference to FIG. 1 is a cooler, 2 is a cold air blowing fan, 3 is a rear partition plate, and 4 is a freezer compartment decorative board, which uses the cold air blowing fan to blow the cold air around the cooler 1 cooled by the operation of a compressor (not shown). 2, and the air is circulated through a ventilation path constituted by a rear partition plate 3 and a decorative freezer panel 4 as shown by the arrows in the figure.

5 is a turbulence prevention plate, and the cold air blowing fan 2
It is located in a conical shape on the front surface where turbulent flow is likely to occur, and is intended to prevent vibrations from propagating to the freezer compartment decorative panel 4 due to turbulent flow, and also to reduce wind noise. Further, since the turbulence prevention plate 5 is usually formed by injection molding or the like, it needs to have a uniform thickness, and as shown in the figure, the inside in the forward direction is hollow. 6 is an interior light, and 7 is a lamp cover.

Next, in FIG. 2, a recess 4a is provided from the freezer compartment decorative board 4 in this hollow space, and an interior light 6 is attached to the recess 4a via an interior light socket 6a, thereby removing the lamp cover. 7 protruding from the freezer compartment decorative board 4 can be kept small, so that the food storage and design in the freezer compartment are improved accordingly.

Further, FIG. 3 shows an example in which the interior lamp 6 is directly attached to the hollow space of the turbulence prevention plate 5, and the protruding dimension of the lamp cover 7 can be further reduced, and the cold air blowing fan 2 The cold air discharged from the refrigerator can prevent the temperature rise of the interior light 6 and prevent thermal deformation of resin parts such as the turbulence prevention plate 5, the freezer compartment decorative panel 4, and the lamp cover 7. less likely to have an impact.

Furthermore, the structures explained in FIGS. 2 and 3 both utilize the hollow space of the turbulence prevention plate to
It prevents the turbulent flow of cold air, which is the purpose of the conventional turbulence prevention plate, and can be provided without any adverse effects on the circulation of cold air between the back partition plate and the freezer compartment decorative plate.

[0016]

[Effects of the Invention] Since the present invention is configured as described above, (1) a refrigerator can be placed on the rear side of the freezer compartment without obstructing the circulation of cold air in the cold air ventilation path formed between the rear partition plate and the decorative panel of the freezer compartment; Interior lights can be installed.

(2) It is possible to reduce the protruding dimension of the internal light, thereby improving the food storage property and design.
