Problems solved by technology

[0006] In the prior art with this structure, if the certain time is short, the user will be warned during normal use, which will cause discomfort to the user and cause a problem that the usability is significantly reduced.
[0007] On the other hand, if it takes a long time to start the warning, the door is opened in vain, and the cold air in the refrigerator is leaked. , to cool it will increase the power consumed
Therefore, it is necessary to unnecessarily widen the frame body provided with the display part, or make the part provided with the display part wider than other parts, which is a problem in both design and manufacture.

[0023] Figure 1-Figure 6 The refrigerator of the first embodiment is shown.

[0024] First, refer to figure 1 A schematic structure of the refrigerator of this embodiment will be described. figure 1 It is a schematic explanatory drawing of the refrigerator of this Example. exist figure 1 Among them, the refrigerator generally indicated by reference numeral 1 is a refrigerator in which a plurality of storage rooms with different temperature ranges are stacked up and down. The refrigerator 1 divides the front open frame body by a partition wall (not shown), and has a drawable door or a pull-out door in front of the divided storage rooms, thereby constituting a plurality of closed storage rooms. In addition, the housing includes refrigeration cycle devices such as compressors, heat exchangers, fans, baffles, and controllers (not shown), and temperature adjustment mechanisms, and keeps the temperature of each of the storage chambers constant.

[0060] Below, refer to Figure 7 A second embodiment will be described. Figure 7 is a sectional view of the handle of the refrigerator of the second embodiment, Figure 7 (a) is a longitudinal sectional view, Figure 7 (b) is a cross-sectional view of the grip portion. exist Figure 7 In this embodiment, the opening display device 200 is shown in the handle 14 . Figure 7 In (a), the upper part shows the opening and closing door 11 . The handle 14 is bent at one end in the longitudinal direction, and the end of the bent portion is attached to the opening and closing door 11, and the other end is a free end. On the surface (front side) of the handle 14 is provided a strip-shaped opening display window 105 along the length direction of the handle 14 . Further, inside the handle 14 which is the inner side of the opening display window 105 , a substantially rod-shaped opening display device 200 is provided along the longitudinal direction of the handle 14 .

Abstract

The invention relates to a refrigerator which has open and close switches (61) arranged on a pair of open-and-close doors (11), display devices (200) arranged on panels (103) respectively arranged at the lower parts of the doors, pull handle dents (106) formed at the lower ends of the panels and a control device (60) ensures that the display devices are on state when the doors are opened, wherein each display device has a club-shaped transparent diffused plate (202) and a light source (201) arranged in the longitudinal direction of the diffused plate; the front face P1 which is arranged at one side of the long side of the diffused plate adjacent to a door surface is made into a flat surface, while a back face P2 opposite to the front face is made into a concavo-convex shape; moreover, a large curved surface which is tapered off from one end in the longitudinal direction provided with the light source to the other end is formed; the control device (60), which controls the gradual lighting up of lamps from the light source side to the other end in the longitudinal direction and the gradual black out of the lamps from the other end to the light source side, ensures that both display devices and the pull handle dents are arranged side by side in vertical direction.

Description

technical field [0001] The present invention relates to a refrigerator which detects whether a door is opened and notifies the user that the door has been opened. Background technique [0002] In existing refrigerators, there are various schemes for notifying the user that the door has been opened. For example, when the freezer door or the refrigerator door is opened, the door detection device starts and after a certain period of time (about 30 seconds), the sound memory device starts and makes a corresponding voice (for example, "The door is open. Please close it. ”), there is also an operation display part on the surface of the opening and closing door, and the operation display part is equipped with lights that display various switches and the switching status of the storage room, etc., and a timer is used to count and display the door on the display device. Opened time. [0003] In addition, a part having a display portion which notifies that the door is known to be op...
