TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an interior lamp mounting device installed in a refrigerator.
[0002]
[Prior art]
Electric refrigerators are equipped with interior lamps composed of illumination lamps and sockets. In recent years, with the diversification of sales partners, interior lamp mounting devices that meet the safety standard requirements of each country are required. .
[0003]
There are the following two general international safety standards as safety standards for interior lights. First, it is required that the electric refrigerator as a product conforms to safety standards. For example, there are international safety standards IEC60335-1 and IEC60335-2-24.
[0004]
IEC 60335-1 is the safety of electrical equipment for home and similar applications Part 1: General requirements (Safety of household and similar electrical appliances. Part 1: General requirements.).
[0005]
IEC 60335-2-24 describes the safety of electrical appliances for home and similar applications Part 2: Individual requirements for refrigerated appliances and ice cream and ice making appliances (Particle refrigeration repeaters, Part 2). , Ice-cream apps and ice-markers.).
[0006]
According to the international safety standards IEC60335-1 and IEC60335-2-24, a structure in which a finger does not touch the charged part when the interior light is replaced is described as a single unit of the interior light socket or a socket of the interior light and the surrounding resin molded body. Has requested. In this international safety standard, the diameter of the base of the illumination lamp is not specified, and generally E12 (about 12 mm) is used.
[0007]
Secondly, when parts are required to conform to international safety standards, for example, there is international safety standard IEC60238. IEC60238 is a standard required for Edison screw lampholders. According to this standard, the socket alone is required to have a structure in which a finger does not touch the charged part when the interior light is replaced. In this international safety standard, the minimum illumination lamp base diameter is practically E14 (about 14 mm).
[0008]
On the other hand, in the illumination lamp, since the internal filament portion generates heat when energized, when the heat generation temperature is high, there is a concern that the surrounding resin molded product may soften beyond its heat resistant temperature.
[0009]
Therefore, in the conventional interior light mounting device for an electric refrigerator, the illumination lamp, the socket and the resin molded body, which are its components, are selected and arranged so as to conform to the above international safety standards. Since there is a type (including power consumption), an individual resin molded body was molded to cope with this.
[0010]
[Problems to be solved by the invention]
However, creating individual resin moldings according to the type of interior light (including power consumption) requires preparing a plurality of types of resin moldings, which increases the number of product dies. Therefore, there is a problem that the production cost increases.
[0011]
Therefore, the present invention uses two types of interior lamps separately and individually uses the same resin molded body in order to individually conform to the above two types of requirements in each country, thereby ensuring safety and reducing production costs. It is an object of the present invention to provide a refrigerator interior light mounting device that can achieve the above.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes a resin molded body to which an interior lamp composed of an illumination lamp and a socket is attached, wherein the resin molded body corresponds to a plurality of types of interior lamps, and a socket to which the socket is attached. It is an object of the present invention to provide a refrigerator interior light mounting device, comprising: a mounting portion; and a common lamp window hole that allows a lighting lamp to face a lighting room.
[0013]
According to the above configuration, the resin molded body is provided with a socket mounting portion corresponding to a plurality of types of interior lamps and a common lamp window hole. Only one mold is required, and the production cost can be reduced.
[0014]
Since the resin molded body is for holding and fixing the interior lamp, a configuration having the socket mounting portion and the window hole is sufficient, but in addition to this, the illumination formed in the refrigerator interior It may be integrally formed so as to also form the chamber wall of the chamber. Thereby, the number of parts constituting the refrigerator can be reduced, and the cost of the resin molding die can be reduced.
[0015]
The plurality of types of interior lamps are not particularly limited, but typical ones are, for example, a type in which a lamp screw-in type socket has no tubular skirt portion at the tip and another type. One is a type in which a lamp screw-type socket is provided with a tubular skirt portion at the tip.
[0016]
The international safety standard required for both types requires that no finger enters between the window hole and the lamp outer periphery when the interior light without a skirt is installed. In the case of an interior light with a skirt, it is required that no finger enters between the inner periphery of the skirt and the outer periphery of the lamp. However, in the case of an interior light with a skirt portion, the skirt portion is also mounted so as to protrude toward the lighting room through the window hole, so that the window hole is required to be larger than the outer diameter of the skirt portion.
[0017]
Therefore, the hole diameter of the window hole is set so that fingers cannot be inserted between the lamp and the outer periphery of the interior light without skirt, and the socket diameter with the skirt is set larger than the outer diameter of the skirt. Should be adopted.
[0018]
In addition, the hole diameter of the window hole needs to be set to a size that can prevent softening due to heat generated by the lamp, in other words, a size that can maintain its shape even when heat is generated by the lamp. Focusing on the distance between the resin socket and the window hole of the molded resin body that surrounds it, the common window hole is set to a hole diameter that can be inserted into the skirt part of the interior light with a skirt, so there is no skirt. When the interior light is installed, it can be said that the distance between the outer periphery of the lamp and the surrounding window hole can be set to be large by the thickness of the skirt. Therefore, in the case of an interior lamp without a skirt, a lamp having higher power consumption than that of an interior lamp with a skirt portion can be used.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an electric refrigerator to which the present invention is applied.

Further, a compression motor 22 for compressing the refrigerant is provided below the rear rear surface of the refrigerator compartment 3.
[0021]
In the refrigerator compartment 3, a resin molded body 10 molded of a thermoplastic resin on a central inner wall on a back surface thereof is assembled and arranged. The resin molded body 10 constitutes a rear inner wall of the interior of the refrigerator, and an illumination room 11 is recessed inside the interior of the refrigerator, thereby forming a room wall of the illumination room 11. The lighting room 11 is provided with an interior lamp 14 including an illumination lamp 12 and a socket 13, and a light-transmitting illumination cover (not shown) is detachably attached to the front surface.
[0022]
Of the interior walls of the illumination room 11, a lamp window hole 15 is formed in the upper interior wall, in which at least the illumination lamp 12 of the interior lamp 12 fixed to the back side of the resin molded body 10 faces the illumination room 11 side. Have been. The illumination lamp 12 illuminates the inside of the storage from the illumination room 11 through the window hole 15.
[0023]
The illumination lamp 12 is composed of a lamp section containing a filament and a screw-in base. The socket 13 has a cylindrical structure for screwing the base, and is formed on the outer periphery of the back surface of the resin molded body 10. A locking portion 17 for locking to the socket mounting portion 16 is formed so as to protrude.
[0024]
In the present embodiment, the window hole 15 is formed in a circular shape in accordance with the circular cross section of the illumination lamp 12. The hole diameter can penetrate the lamp 12 and the socket 13 for a plurality of types of interior lamps 14 and for one interior lamp 14b, and prevent the surrounding resin molded body 10 from being softened due to lamp heat generation. In addition, it is set so that a gap can be ensured, and it is impossible to insert a finger between the other interior lamp 14a and the outer periphery of the penetrated lamp 12, and the resin around the lamp 12a is heated by the heat generated by the lamp. The gap is set so as to secure a gap that can prevent softening of the molded body 10. The configuration of these interior lights 14a and 14b will be described later.
[0025]
In addition, the socket mounting portion 16 is formed integrally with the resin molded body 10 on the back surface of the resin molded body 10 and above the outside of the illumination room 11. In the mounting portion 16, a boss portion 18 for screwing the locking portion 17 of the socket 13 and a positioning pin 19 for positioning the locking portion are arranged at intervals on both sides of the body of the socket 13. ing. Further, a plurality (two) of these mounting portions 16 are installed in the length direction (up and down direction) of the socket 13 corresponding to the plurality of types of interior lamps 14.
[0026]
Further, in the vicinity of the window hole 15 of the resin molded body 10, a concave portion 21 is formed at a distance from the lamp 12 to be installed, so as to avoid softening due to heat generated by the lamp.
[0027]
As shown in FIG. 3, the electric circuit of the interior light 14 is configured such that a fan motor 8, a compression motor 22, and a series connection of the door switch 7 and the interior light 14 are connected in parallel to a power supply. The operating current of the illumination lamp 12 is about 0.05 A (when 220 V is applied). When the door is opened, the contact of the door switch 7 is closed, the power is controlled, and the interior light 14 emits light and generates heat. When the door is closed, the contact of the door switch 7 is opened, the power is stopped, and the interior lamp 14 is turned off.
[0028]
Here, typical examples of a plurality of types of interior lamps 14 will be given. One of them (hereinafter, referred to as a first interior lamp 14a) is a type in which the lamp 12 has no screw-shaped socket 13 and a tubular skirt portion at the tip end. When the first interior lamp 14a is mounted, the mounting method is such that only the illumination lamp 12 faces the illumination room 11 through the window hole 15. The other one (hereinafter, referred to as a second interior lamp 14b) is of a type in which the lamp 12 is provided with a cylindrical skirt portion 24 in a screw-in socket 13 at the tip thereof. When the second interior lamp 14b is mounted, the mounting method is such that not only the lamp but also the skirt portion 24 faces the illumination room 11 through the window hole 15.
[0029]
A case where the first interior light 14a using the socket 13 without the skirt portion 24 is attached will be described with reference to FIGS. 5 is a view of the resin molded body in which the first interior lamp 14a is incorporated, as viewed from the inside of the refrigerator, FIG. 6 is a plan sectional view of FIG. 5, FIG. 7 is a rear view of FIG. 5, and FIG. FIG. In FIG. 8, reference numeral 27 denotes a test finger (test finger) for simulation confirmation defined by the IEC60335-1 standard.
[0030]
When the first interior lamp 14a is attached, according to the international safety standards IEC60335-1 and IEC60335-2-24, a finger is placed at the interval D between the outer periphery of the lamp 13 and the inner edge of the window hole 15, as shown in FIG. It is required not to enter. Specifically, the international safety standards IEC60335-1 and IEC60335-2-24 do not specify the diameter of the base of the illumination lamp 12, so that the generally used illumination lamp 16 will be described. (About 12 mm) and the lamp outer diameter is T20 (20 mm). When the first interior light 14a having this size is attached, the distance between the first interior light 14a and the window hole 15 is set so that a finger cannot enter.
[0031]
On the other hand, a case where the second interior lamp 14b using the socket 13 having the skirt portion 24 is attached will be described with reference to FIGS. 9 is a view of the resin molded body in which the second interior lamp 14b is incorporated as viewed from the inside of the warehouse, FIG. 10 is a plan sectional view of FIG. 9, FIG. 11 is a rear view of FIG. 9, and FIG. FIG.
[0032]
When the second interior lamp 14b is installed, according to the international safety standard IEC60238, it is required that no finger enters between the lamp 12 and the socket skirt portion 24 when the illumination lamp 12 is replaced. The gap with the window hole 15 is not specified. For the second interior lamp 14b, the minimum diameter of the base of the illumination lamp 12 is set to E14 (about 14 mm) according to the international safety standard IEC60238. Is E14 (about 14 mm) and the lamp outer diameter is T20 (20 mm). When attaching the second interior lamp 14b of this size, the distance from the window hole 15 needs to be larger than the outer diameter of the skirt portion 24.
[0033]
Accordingly, the hole diameter of the window hole 15 corresponding to the two types of interior lamps 14a and 14b is large enough that a finger does not enter a gap between the inner edge thereof and the lamp outer diameter of the first interior lamp 14a. And it is large enough to allow the skirt portion 24 of the second interior light 14b to pass through.
[0034]
Further, if consideration is given to the prevention of softening of the resin molded body 10 due to the heat generated by the lamp, the distance between the outer diameter of the lamp of the first interior lamp 14a and the window hole 15 is such that a finger cannot enter, and the second interior lamp is further reduced. The outer diameter of the socket skirt portion 14b is set to be larger than the outer diameter. On the other hand, the outer diameter of the second interior lamp 14b and the inner surface of the skirt portion 24 of the socket 13 are set so that a finger cannot enter. Since the common window hole 15 is set to a hole diameter into which the skirt portion 24 of the skirted interior lamp 14b can be inserted, when the first interior lamp 14a without the skirt is attached, the thickness of the skirt 24 is reduced. Since the distance between the outer periphery of the lamp and the peripheral window hole 15 is increased, the first indoor lamp 14a can be set to have a larger calorific value than the second indoor lamp 14b.
[0035]
Therefore, in the present embodiment, the first interior lamp 14a (base diameter E12) whose power consumption is set to 15 W is used, and the second interior lamp 14b (base diameter E14) is the first interior lamp 14b (base diameter E14). The power consumption is set to 10 W, which is lower than that of the interior lamp 14a.
[0036]
Also, the supply voltage may differ depending on the country of sale. Table 1 summarizes the lamp rated voltage, the base diameter, the lamp diameter, and the rated power consumption for the first interior lamp 14a and the second interior lamp 14b. When supplying to a sales partner country, a lamp with a rated voltage according to the supply voltage in that country may be selected.
[0037]
[Table 1]

[0038]
In addition, in both the first interior light 14a and the second interior light 14b, when the illumination lamp 12 is completely removed, the contact of the charged portion of the finger with the tip in the socket 13 is performed according to the international safety standard IEC60335-1. And IEC60335-2-24 or the international safety standard IEC60238.
[0039]
It should be noted that the present invention is not limited to the above embodiment, and it is needless to say that modifications and changes can be made within the scope of the present invention. For example, in the above embodiment, two types of interior lights have been described, but it is needless to say that three or more types of interior lights can be applied. Further, in the above-described embodiment, an example has been described in which a plurality of socket mounting portions are provided corresponding to a plurality of types of interior lamps, but a common socket mounting portion may be used.
[0040]
【The invention's effect】
As is apparent from the above description, according to the present invention, since the socket mounting portion and the hole diameter of the common lamp window hole are set for a plurality of types of interior lamps, the common resin molded body is used. Can be used, and the cost of the molding die can be reduced accordingly.
