Description

Drawer of refrigerator and refrigerator

Technical Field

The invention relates to the technical field of freezing and refrigerating devices, in particular to a drawer of a refrigerator and the refrigerator.

Background

The drawer display image of the existing refrigerator is characterized in that patterns are printed on the surface of a drawer, and the patterns are illuminated by light rays to emit light so as to present a projection effect, so that the drawer display image is stiff and the patterns cannot be changed. In the refrigerator, in order to display and adjust the temperature of the drawer chamber on the drawer door panel, the prior art is to provide a control panel on the drawer door panel. The control panel needs to be powered by leading out a power supply on the box body through a cable with variable length arranged in a slide way or a slide rail of the drawer. Because the drawer door needs to be drawn and pulled for a long time (drawing and pulling tests are required for more than 15 ten thousand times), and the drawer used as a freezing chamber further requires that the used cable can normally deform at a low temperature below 18 ℃ below zero, the requirement of the existing refrigerator on the cable with variable length is very high, and the cost of the drawer provided with the control panel is far higher than that of the common drawer. Furthermore, the cable lines are at risk of ageing, hardening or long-term wear and tear.

The refrigerator 100 of the embodiment of the present invention may generally include: the refrigerator body 110, the first door 120, the drawer 130 and the third door 140. The case body 110 defines a plurality of storage compartments therein. The first door 120 is pivotally disposed at a front side of one storage compartment via a hinge. A drawer 130 is arranged in the storage compartment below the storage compartment. The drawer 130 includes: a drawer body 200, a front panel assembly 300, and a top cover assembly 400. A storage chamber is defined in the drawer body 200. The front panel assembly 300 is disposed in front of the drawer body 200. The upper cover assembly 400 is overlapped on the liner rib of the liner of the cabinet 110 and covers the upper portion of the drawer body 200. The front end of the upper cover assembly 400 is provided with a projection device 201 for projecting an image downward.

The top plate 302 has a light-transmitting structure 321; forming a projection area 301 on a front plate 303; a reflecting cavity 350 is formed between the rear end plate 304 and the front end plate 303, and a reflecting structure 351 is arranged in the reflecting cavity 350; the projected light 204 emitted from the external projection device 201 is projected toward the reflective cavity 350 through the light-transmitting structure 321, and reflected by the reflective structure 351 to form an image on the front panel 303.

Since the drawer 130 of the refrigerator 100 of the present invention is provided with the projector 201 at the front end of the upper cover assembly 400 and the projection area 301 is formed on the front panel 303 of the front panel assembly 300, the projected image 202 can be displayed on the front panel 303 of the front panel assembly 300. The projection area 301 formed on the front panel 303 can be conveniently viewed by people, and on the other hand, the area of the front panel 303 is large, so that the projection image 202 can be enlarged as required.

In order to facilitate the viewing of the projected image 202, the front plate 303 is a transparent structure 330 at least at the location of the projection area 301.

The reflective structure 351 can be any structure that can reflect light, such as a reflective film disposed on the rear end plate 304 for reflecting light, and a reflective plate disposed separately for reflecting light.

In some embodiments, the rear end plate 304 has a multifold surface formed by several slopes 352 connected end to end in sequence, the multifold surface forming a reflective structure 351. In one embodiment, the rear end plate 304 is integrally disposed at an angle, and the multifold surface forms an obtuse angle with the bottom plate 308 of the drawer body 200. For the projected image 202 to show properly, the ramp 352 is configured such that the cast ray 204 is reflected horizontally back and forth upon reaching the ramp 352.

In other embodiments, a reflective plate is disposed within the reflective cavity 350; the reflecting plate is a multifold element formed by connecting a plurality of inclined planes 352 end to end in sequence, and a reflecting structure 351 is formed on the surface of the reflecting plate.

In one embodiment, the front panel assembly 300 further includes left and right side panels 307; the left and right side plates 307 are opaque structures to prevent other light from affecting the projection. Similarly, on the top plate 302, except the light-transmitting structure 321, the rest regions are light-tight structures. The light-transmitting structure 321 may be made of a transparent PS material in a partial region of the top plate 302.
