Further, the lighting device used for the showcase is required to not only illuminate the products in the refrigerator but also illuminate the transparent shade facing the front side of the showcase. In order to satisfy multiple lighting applications in this way, it is known to use multiple lighting devices in one showcase, but in order to reduce the number of parts and reduce power consumption in order to reduce costs, a single lighting device is used. It is known that the lighting device of the above is used to illuminate the interior of the refrigerator and the shade. In general, showcases that use directional LED lighting are arranged with the optical axis direction facing the display room inside the refrigerator because the lighting inside the refrigerator is prioritized, and the shade lighting is somewhat more than the optical axis direction. It is known that it is illuminated by weak light emitted in the angular direction of the above or by light transmitted through a reflector.

However, depending on the store where the showcase is installed, the lighting inside the store may be sufficient and it may also function as lighting for the display room in the warehouse. In such a store, in the showcase where the lighting inside the refrigerator is prioritized as described above, not only the power is consumed for the wasteful lighting, but also the lighting for the shade may be insufficient.

Here, the front end portion 52 and the first reinforcing folded portion 74 are arranged at substantially the same height, and are arranged so as to sandwich the upper portion of the first cover piece 41 of the lighting cover 31. By arranging in this way, deformation such as bending and distortion of the lighting cover 31 can be suppressed more firmly. Further, by providing the reflecting surface on the lower surface reinforcing plate 50, it is possible to improve the reliability at low cost without increasing the number of unnecessary parts.

Since the light diffusing portion 29a of the LED lighting device 28 faces the front side, the optical axis O1 faces the front of the showcase 1. In the present embodiment, as shown in FIG. 3, the optical axis O1 is oriented toward the first cover piece 41 of the lighting cover 31. Since the illumination light emitted by the LED light source 30 is directional, the illumination light illuminates a desired place such as a plurality of display shelves 18 arranged in the facing illumination cover 31 and the lower internal display chamber 10. As described above, the diffused light around the optical axis O1 of the LED light source 30 is set.

For example, the LED light source 30 of the LED lighting device 28 used in the present embodiment has a beam angle of ± 90 degrees with respect to the optical axis O1. Here, the optical axis O1 is not the angle with the highest brightness, but the central angle of the beam angle. The peak angle direction having the highest brightness is preferably any one of an angle toward the lighting cover 31, an angle toward each shelf board 18 arranged in the internal display chamber 10, and an angle toward the reflective surface portion 51. In the present embodiment, the peak angle direction O2 having the maximum brightness toward the illumination cover 31 is provided. Here, in the case of an LED lighting device having a plurality of peak angles, at least one peak angle direction is directed toward the shade, and the other peak angle directions are directed toward the display room side in the refrigerator or the reflecting surface. May be good.

The light emitted from the LED lighting device 28 is distributed around the optical axis O1 with the highest brightness in the peak angle direction O2.
As in the present embodiment, since the lighting cover 31 is provided in the direction of the optical axis O1 of the LED lighting device 28, stronger light is emitted to the first cover piece 41 on the front side of the lighting cover 31 that functions as a shade. By being irradiated, the appearance of the shade can be improved even in a bright store.

The showcase 1 includes a control unit 81. A lead wire (not shown) drawn from the LED lighting device 28 is connected to the control unit 81. Further, a panel unit 80, a blower 68, a temperature sensor for measuring the temperature inside the refrigerator (not shown), a valve device used for cooling operation, and the like are connected.

The operation of the showcase 1 is controlled based on the information set by the operation units of the control unit 81 and the panel unit 80 and the information from the temperature sensor and the like. That is, in order to make the temperature inside the refrigerator appropriate, the rotation speed of the blower 68 and the opening degree of the valve device are adjusted to light the LED lighting device 28. The LED lighting device 28 may have not only ON / OFF but also a dimming function or a device whose color temperature changes.

Next, the operation of the showcase 1 configured as described above will be described.
The cooler 69 is cooled by the refrigerant cooled by the refrigerating circuit. When the showcase 1 is activated, the control unit 81 supplies electric power to the LED light source 30 to turn on the LED light source 30. The illumination light emitted by the LED light source 30 irradiates the illumination cover 31, each display shelf 18, and the like.

When the control unit 81 supplies electric power to the blower 68, the blower 68 causes air A1 to flow as shown in FIG. This air A1 is cooled by the cooler 69. A part of the cooled air A2 becomes the air A3 that flows downward through the rear duct D2, the upper duct D3, and the rectifying member 16a of the outlet 16. The air A3 suppresses the air in the display chamber 10 in the refrigerator from flowing out.

The air A3 flows into the lower duct D1 through the suction port 66, and flows toward the cooler 69 again by the blower 68.
A part of the cooled air A2 flowing in the rear duct D2 flows into the internal display chamber 10 from a rear outlet (not shown) provided on the rear plate 13, and cools the inside of the refrigerator.

As described above, according to the showcase 1 of the present embodiment, it is possible to efficiently illuminate the shade of the lighting cover 31 and the display room 10 in the refrigerator without providing a useless lighting device, and the number of parts is increased. It is possible to provide a showcase with low power consumption.
Further, by providing the reflecting surface portion 51 on the lower surface reinforcing plate 50 arranged so as to face the LED lighting device 28, useless irradiation light from the LED lighting can be used for lighting the internal display room 10. ..
Further, by having the rising inclination angle θ1 from the horizontal of the main body plate portion 23 to which the LED lighting device 28 is fixed, the amount of irradiation light over the entire beam angle from the LED lighting device 28 is suppressed and the power consumed for lighting is reduced. While suppressing it, it is possible to secure the amount of irradiation light to the lighting cover 31 and the amount of irradiation light to the display chamber 10 in the refrigerator.

In particular, as in the present embodiment, by directing the optical axis of the LED lighting device 28 toward the shade side of the lighting cover 31, the power consumption of the LED lighting device 28 is sufficiently secured while sufficiently illuminating the shade of the lighting cover 31. Can be suppressed. For example, in a well-lit store, the amount of light to the display room inside the showcase can be secured to some extent by the lighting inside the store, and it is necessary to give priority to the lighting from the lighting device attached to the showcase 1 to the lighting inside the showcase. In the absence of the shade, the amount of irradiation light of the shade can be sufficiently secured, and the appearance of the showcase 1 itself can be improved.

Since the LED lighting device 28 is arranged above the upper end of the panel 80, the visibility of the panel 80 is good, and a worker such as a store manager who has installed the showcase can check the display of the panel 80 and perform setting operations. Good workability can be ensured when performing work or the like.
In particular, the LED lighting device 28 is located on the same plane (main body plate portion 23) in which the lower end of the first cover piece 41 of the lighting cover 31, which is a shade, is located equal to or below the lower end of the support plate 22 and is inclined at the rising inclination angle θ1. By arranging the panel unit 80 below the LED lighting device 28, the workability can be improved without the operator directly looking at the irradiation light from the LED lighting device 28.

A notch 48a is formed in the lower end locking member 35, and the convex portion 43 provided at the lower end portion of the lighting cover 31 is locked to the notch 48a, so that the lower end locking member 35 engages with the lighting cover 31. Stop. Therefore, the lower end locking member 35 can hold the position of the lower end portion of the lighting cover 31, and can suppress the wobbling of the lower end portion of the lighting cover 31 in the front-rear direction.

Further, since the lower end locking member 35 is located below the LED lighting device 28 and is formed so as to be located below the optical axis O1, it does not serve as a shield that casts a shadow on the shade.

In this embodiment, the lighting cover 31 covers the LED lighting device 28 in the front and above.

Although the cooler 69 of the showcase 1 is connected to a refrigerating circuit provided outside the showcase 1, this refrigerating circuit may be built in the showcase 1.

Further, in the above embodiment, the first cover piece located on the front side of the lighting cover 28 has been described as a shade, but the present invention is not limited to the first cover piece 41, and the second cover piece 42 side on the upper surface side is also included. It may be included and configured as a shade. Further, the shape of the shade may be not only a flat plate shape but also a shape having a curved surface, and may be configured as various shapes.

As shown in FIG. 1, the showcase 1 may be installed by connecting a plurality of main body portions 11 in the left-right direction, but when the display chambers 11 in the refrigerator are connected to each other without providing the partition plate 5. A plurality of adjacent lighting covers 28 may be installed in close contact with each other. Further, the lighting cover 28 straddling the plurality of showcases 1 may be continuously formed. As a result, the appearance of the shade portion of the lighting cover 28 can be improved.

Further, when a plurality of showcases 1 are connected without having the partition plate 5 as described above, the height directions of the LED lighting devices 28 arranged in the adjacent showcases 1 are staggered in a staggered manner. You may. Further, the LED lighting device 28 may be arranged in a staggered manner so as to overlap in the left-right direction. By arranging in this way, it is possible to sufficiently secure the illumination light to the shade at the connecting portion of each of the continuous showcases 1, and to reduce the brightness of the shade due to insufficient illumination to the shade at the connecting portion. Can be done. In order to arrange the LED lighting devices 28 in an overlapping manner in this way, the left-right length of the LED lighting arrangement may be longer than the left-right length of the main body 11 of the showcase 1.
