Problems solved by technology

[0009] In this conventional refrigerator, it is difficult to set the temperature of each storage compartment and determine the food to be stored.
In particular, in a storage room with a plurality of compartments each having a different temperature zone, it is difficult to judge the difference in the temperature setting status of each compartment and the food to be stored.

Embodiment approach 1

[0043] figure 1 It is a cross-sectional view of refrigerator 1001 according to Embodiment 1 of the present invention. Refrigerator 1001 includes main body 1 . The main body 1 is provided with: an inner case 22 formed by vacuum molding a strong resin such as ABS resin; an outer case 23 made of a metal material such as a pre-coated steel plate; The insulating wall 24 formed in the space between 23. As the foam heat insulator, rigid urethane foam, phenolic foam, styrene foam, etc. are used, for example. It is more preferable to use hydrocarbon cyclopentane as the foaming material from the viewpoint of preventing warming.

[0044] In the space between the inner case 22 and the outer case 23 before foaming the foam heat insulator, the vacuum heat insulating material 25 is closely adhered to the outer case side with an adhesive member such as hot melt. The vacuum heat insulating material 25 has a thin planar shape so that it can be arranged within the thickness of the main body...

Embodiment approach 2

[0082] figure 2 It is a cross-sectional view of refrigerator 2001 according to Embodiment 2 of the present invention. The light source 213 is provided in the switching chamber 206 . The machine room 212 that houses the main components of the refrigeration cycle such as the compressor 216 and the condenser is provided above and behind the refrigerator room 202 in the main body 201 .

[0083] Conventionally, the machine compartment is located behind the freezer compartment 203 at the lowermost part of the main body 201, so the volume of the freezer compartment 203 is reduced. However, by arranging the machine room 212 on the back of the uppermost part of the refrigerator room 202 that has not been effectively used in conventional refrigerators, the part of the conventional machine room can be used as a storage room, so it is possible to increase the size without increasing the external size. The volume of the freezer compartment 203.

[0084]In addition, in the past, in orde...

Embodiment approach 3

[0086] image 3 It is a cross-sectional view of refrigerator 3001 according to Embodiment 3 of the present invention. In refrigerator 3001 , light source 313 is provided on the top surface in switch chamber 306 , and operation panel 314 is provided on inner wall 302A of refrigerator compartment 302 .

[0087] Figure 4 is a cross-sectional view of the light source 313 provided in the switching chamber 306 . The light source 313 has a light emitting diode (LED) 326 that irradiates ultraviolet light with a peak wavelength of 387 nm, an LED 327 that irradiates blue light with a peak wavelength of 468 nm, a substrate 328 on which the LEDs 326 and 327 and a control unit 328A are mounted, and a substrate 328 that covers the LEDs 326 and 327 and the substrate 328. Cover 329. The light source 313 is provided on the top surface of the switching chamber 306 substantially in the center of the switching chamber 306 or near the center. LED326,327 irradiates light downward. Gasket 330 ...

Abstract

The invention provides a refrigerator comprising a body having compartments partitioned by heat insulation walls, a storage chamber provided in one of the compartments, a light source provided in the storage chamber, and a control section capable of setting the temperature of the storage chamber to different temperature zones. The light source can emit colors different from each other. The control section selects, according to a set temperature zone of the storage chamber, light of one color out of the colors and causes the light source to emit the light. The refrigerator facilitates recognition of temperature conditions of each chamber and is therefore easy to use.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of May 22, 2006, an application number of 200680018237.6 (the international application number is PCT / JP2006 / 310140), and an invention name of a refrigerator. technical field [0002] The present invention relates to refrigerators. Background technique [0003] In recent years, in order to meet the diverse needs of customers, refrigerators that not only improve the storage performance of food but also improve the ease of use from the viewpoint of ergonomics are popularized. [0004] Figure 12 It is a cross-sectional view showing a conventional refrigerator described in JP-A-2000-186883. This refrigerator is equipped with the main body 1 of a heat insulation structure. The main body 1 is composed of an upper refrigerator compartment 2, a lower freezer compartment 3, a vegetable compartment 4 adjacent to the refrigerator compartment 2 between the refrigerator compartm...
