Since the light source body 34 of the illumination device 33 is arranged obliquely rearward, the illumination by the illumination device 33 can be brightened up to the inner part of the low temperature storage chamber 23 and stored in the low temperature storage chamber 23. You can clearly see the food.

  And since the illuminating device 33 of the said low-temperature storage chamber 23 is provided in the front-end part of the cover 24 which forms the low-temperature storage chamber 23, the front-end part of the cover 24 becomes bright, food, a pot on the said cover 24 Even if a container such as the one is placed, the lighting can be reliably recognized. Therefore, the user can recognize the lighting of the lighting device 33 in the low temperature storage chamber 23 without bending down, and the usability is improved.

  Further, even if the container placed on the cover 24 falls and the liquid flows out and flows to the front end portion of the cover 24 provided with the lighting device 33, the liquid is provided at the front end portion of the cover 24. Since the front portion of the lighting device 33 is covered with the water slice 38, the liquid drops downward without entering the lighting device 33. Therefore, it is possible to reliably prevent a failure or the like of the lighting device 33 caused by providing the lighting device 33 at the front end portion of the cover 24.

  On the other hand, when food is taken in and out of the low temperature storage chamber 23, the food or a hand holding the food may touch the lighting device 33 that is positioned above the opening of the low temperature storage chamber 23. However, since the illumination device 33 shown in this embodiment covers the lower part of the light source body 34 and the light source body substrate 35 with the transparent cover 37, it can be used with confidence without being broken or short-circuited even when touched by food or hands. It is possible to prevent condensation on the light source body 34 and the light source body substrate 35.

  Further, the lighting device 33 is mounted by engaging the claw piece 40 of the substrate storage portion 36 with the lighting device mounting portion 39 formed of a projecting piece formed on the lower surface of the front end portion of the cover 24, as shown in FIG. As described above, if the light source substrate 35 and the transparent cover 37 are attached to form a unit, the substrate storage portion 36 can be attached by sliding it from one end of the illumination device attachment portion 39. Therefore, work such as screwing is not required, and the number of assembling steps can be greatly reduced, and the productivity is greatly improved.

  Furthermore, since the lead wire 43 of the lighting device 33 is pulled back using the cover 24 and connected to the power supply lead wire from the refrigerator main body 1, the lead wire 43 is attached to the inner surface of the inner box 3 of the refrigerator main body 1. There is no need to provide a recess or the like, and processing can be performed reasonably without inducing complication of the inner box configuration of the refrigerator body 1.

  In addition, in this embodiment, since the lead wire mounting portion 41 is provided in the heat insulating material 27 constituting the cover 24, a concave groove is formed in the heat insulating material 27 itself using the plate thickness of the heat insulating material 27. For example, the lead wire mounting portion 41 can be provided. Therefore, it is not necessary to separately prepare a lead wire mounting member and attach it to the cover 24 to form a lead wire mounting portion, thereby reducing the number of members and the number of assembly steps, and improving productivity. At the same time, cost reduction will be promoted.

  In addition, a wiring cover 42 is attached to the lead wire mounting portion 41 to cover the lead wire 43. The wiring cover 42 is also slid and inserted from one end of the lead wire mounting portion 41, like the lighting device 33. By doing so, the cover claw pieces 44 provided on both sides of the wiring cover 42 can be engaged with and attached to the opening protrusions 44a provided at the opening edge portion of the lead wire attachment portion 41. Therefore, the wiring cover 42 can also be mounted without performing a screwing operation or the like, reducing the number of assembly steps and improving the productivity.

  In the low temperature storage chamber 23 exemplified in this embodiment, the duct portion 29 and the outlet 28 are provided in the heat insulating material 27 constituting the cover 24, so that the cold air from the cold air passage 17 is supplied into the low temperature storage chamber 23. However, it can be cooled at a temperature different from the temperature in the refrigerator compartment. At that time, although not shown, the amount of cold air supplied to the duct portion 29 is adjusted by a damper or the like, so that the low-temperature storage chamber 23 can be switched to a partial chamber or a chilled chamber.

  The outlet 28 is provided so as to open at a position below the lower end of the transparent cover 37 of the lighting device 33 so that the cool air from the outlet 28 closest to the lighting device 33 is blown toward the rear. is there.

  Although the embodiment of the present invention has been described above, the configuration described in the above embodiment is shown as an example for carrying out the present invention, and various modifications can be made within the scope of achieving the object of the present invention. Needless to say.

  The present invention can provide a refrigerator that can store lead wires and the like and can easily perform maintenance work without providing a storage portion such as lead wires on the refrigerator main body side. Therefore, it can be widely applied to many uses such as commercial refrigerators and showcases as well as home use.
