DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reach-in type refrigerated showcase, and more particularly to a mounting structure of a glow starter used for lighting a fluorescent lamp incorporated in a refrigerator.

[0002]

2. Description of the Related Art As a reach-in type refrigerated showcase described above, a glass door is provided on the front of a case body, and the interior lighting is provided behind a frame laid inside the glass door along the front opening of the case body. It is well known that a fluorescent lamp is attached to the lamp. Here, the interior fluorescent lamp is lit using a lighting circuit in which a glow starter (lighting tube) and a choke coil are combined. Regarding the mounting structure of the glow starter, a structure in which a socket of the glow starter is incorporated inside a kick plate (decorative plate) arranged at a lower front portion of a case body, a canopy portion (decorative frame) provided at an upper front portion of the case body. ) Is known (Japanese Utility Model Publication No. 5-39533), or a structure mounted in a cool air outlet of a cool air circulation duct inside a refrigerator (Japanese Utility Model Publication No. 6-18196).

[0003]

The above-mentioned conventional glow starter mounting structure has the following drawbacks. (1) In the structure in which the socket of the glow starter is incorporated inside the kick plate arranged at the lower part of the front surface of the case body, the kick plate must be removed when replacing the glow starter, which is troublesome.

(2) In the structure in which the socket of the glow starter is mounted on the lower surface side of the canopy projecting from the front upper portion of the case body, the mounting height is high (the case body height is as large as about 2 m). When the glow starter is replaced due to a failure or the like, it is difficult to replace the glow starter, and since a part of the glow starter appears to protrude from the lower surface of the canopy portion, the appearance is poor.

(3) The structure in which the socket of the glow starter is mounted in the cool air outlet of the cool air circulation duct has an advantage in appearance that the glow starter cannot be seen from the front of the showcase, but the glow starter and its socket are provided. However, there is a problem that the laminar flow of the cold air curtain that forms an obstacle to the ventilation passage and blows out inside the glass door is disturbed. SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to solve the above-described problems, and to provide a reach-in type in which a glow starter can be easily replaced in the event of a failure without impairing the appearance of the appearance. An object of the present invention is to provide a mounting structure of a refrigerated showcase, particularly a glow starter used for lighting a fluorescent lamp in a refrigerator.

[0006]

In order to achieve the above object, the present invention provides a case body provided with a glass door on a front surface thereof.
And in a reach-in type showcase in which a fluorescent lamp for interior lighting is mounted behind a frame laid along the front opening of the case body, a glow starter socket used for lighting the interior fluorescent lamp is connected to the frame. It shall be installed on the back side.

[0007] In addition, the above-mentioned structure specifically has a structure in which the socket of the glow starter faces the inside of the refrigerator and the socket is built into the inside of the channel-shaped frame. It is good to install close to the socket.

[0008]

According to the above construction, the glow starter and its socket are hidden behind the frame and cannot be seen from the front of the showcase, so that the appearance of the glow starter is not spoiled. And the connecting lead wire between them can be shortened. Moreover, when replacing the glow starter due to a failure or the like, the glow starter can be easily replaced simply by opening the glass door and inserting a hand into the refrigerator.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a detailed mounting structure diagram of the glow starter, and FIG. 2 is a cross-sectional view of the entire reach-in type refrigerated showcase employing the glow starter mounting structure of FIG. In each of the figures, reference numeral 1 denotes a case main body of a refrigerated showcase, 2 denotes a double door type glass door (a door having a structure in which transparent glass is fitted into a door frame) provided on the front surface thereof, and 3 denotes a case main body 1.
A frame-shaped frame (a frame formed by combining channel-shaped steel plates having a U-shaped cross section) laid inside the glass door 2 along the front opening of the glass door 2. The magnetic gasket 2a laid along the periphery closely contacts the outside to prevent outside air from entering the storage. A fluorescent lamp 4 for interior lighting is inserted into a light-transmitting protective tube (not shown) and mounted vertically in the center of the frame 3 and behind the vertical rails arranged at both left and right ends. I have. A lighting glow starter (lighting tube) 5 is provided on the back side of the frame 3 near the upper socket 4a of the fluorescent lamp 4.
The socket 6 is incorporated into the frame with the insertion port 3a facing the inside of the refrigerator. In addition, 7 is a lead wire connecting between the socket 6 and the upper socket 4a of the fluorescent lamp 4, 8
Numerals are product display shelves arranged in the upper and lower tiers in the case main body 1.

In such a configuration, the glow starter 5 screwed into the socket 6 is mounted so that its tip projects rearward from the back surface of the frame 3, and when the glow starter 5 is replaced due to a failure or the like, a glass door is required. After opening 2, put your hands in the chamber and replace the glow starter.

[0011]

As described above, according to the structure of the present invention, the glow starter of the fluorescent lamp in the refrigerator is hidden behind the front frame of the case body and cannot be seen from the front of the showcase, so that the appearance is impaired. And the connecting leads between the glow starter socket and the fluorescent socket are short. In addition, when replacing the glow starter due to a failure or the like, there is an advantage that the glow starter can be easily replaced simply by opening the front glass door and inserting a hand into the refrigerator.
