Abstract

A refrigerating apparatus includes a cabinet body having an open top; a door body ( 2 ) disposed at the top of the cabinet body pivotably around a pivot shaft ( 421 ) so as to open and close the cabinet body; and a light assembly ( 3 ), disposed at a side of the door body ( 2 ) facing the cabinet body ( 2 ) and arranged adjacent to the pivot shaft ( 421 ), wherein the light assembly ( 3 ) includes a PCB ( 31 ), an LED light ( 32 ) and a gravity switch ( 33 ), both the LED light ( 32 ) and the gravity switch ( 33 ) are connected onto the PCB ( 31 ), and the gravity switch ( 33 ) is configured to be switched on to light the LED light ( 32 ) so as to light an interior of the cabinet body when the door body ( 2 ) opens the cabinet body, and switched off to extinguish the LED light ( 32 ) when the door body ( 2 ) closes the cabinet body.

First claim

What is claimed is:

1. A refrigerating apparatus, comprising:
a cabinet body having an open top;
a door body disposed at the top of the cabinet body pivotably around a pivot shaft so as to open and close the cabinet body; and
a light assembly, disposed at a side of the door body facing the cabinet body and arranged adjacent to the pivot shaft, wherein the light assembly comprises a PCB, an LED light and a gravity switch, both the LED light and the gravity switch are connected onto the PCB, and the gravity switch is configured to be switched on to light the LED light so as to light an interior of the cabinet body when the door body opens the cabinet body, and switched off to extinguish the LED light when the door body closes the cabinet body,
wherein the gravity switch comprises:
a casing connected onto the PCB;
a first leading wire disposed through the casing and separated from the casing, wherein the first leading wire is connected onto the PCB; and
a rolling body rollingly disposed in the casing and configured as that the LED light is turned on when the door body opens the cabinet body and the rolling body is in contact with the first leading wire, and the LED light is turned off when the door body closes the cabinet body and the rolling body is separated from the first leading wire,
wherein the casing is connected onto the PCB through a second leading wire, and the second leading wire and the first leading wire are spaced apart from each other in a length direction of the casing.

2. The refrigerating apparatus according to claim 1 , wherein a central axis of the casing along the length direction thereof is perpendicular to a central axis of the pivot shaft, and the first leading wire is disposed adjacent to the pivot shaft.

3. The refrigerating apparatus according to claim 1 , wherein the first leading wire is separated from the casing via a separating piece and the separating piece is disposed between the first leading wire and the casing.

4. The refrigerating apparatus according to claim 1 , further comprising:
a cover body covering the light assembly.

5. The refrigerating apparatus according to claim 4 , wherein the LED light penetrates the cover body, the cover body is provided with a light-cover thereon, and the light-cover is arranged adjacent to the LED light.

6. The refrigerating apparatus according to claim 1 , further comprising:
a light-cover arranged adjacent to the LED light and located at a first side of the LED light away from the pivot shaft.

7. The refrigerating apparatus according to claim 1 , wherein the LED light has a second side facing the pivot shaft and connected onto the PCB obliquely.

8. The refrigerating apparatus according to claim 1 , further comprising:
a delay device connected with the LED light.

9. The refrigerating apparatus according to claim 8 , wherein the delay device is configured to be a capacitor and the capacitor is connected onto the PCB.

10. The refrigerating apparatus according to any one of claim 1 , wherein a plurality of the LED lights is spaced apart from one another on the PCB.

11. The refrigerating apparatus according to claim 1 , wherein the door body has an angle relative to an upper surface of the cabinet body ranging from 0° to 90°.

12. The refrigerating apparatus according to claim 11 , wherein the door body is rotatably disposed on the cabinet body via a hinge device, and the hinge device comprises:
a first hinge disposed on the top of the cabinet body and having a pivoting hole; and
a second hinge disposed at the door body and having the pivot shaft, wherein the pivot shaft cooperates with the pivoting hole so that the door body pivots about the pivot shaft, and the second hinge cooperates with the first hinge via a limiting structure so that the door body pivots relative to the cabinet body from 0° to 90°.

13. The refrigerating apparatus according to claim 12 , wherein the first hinge comprises two side walls spaced apart from each other, two pivoting holes are formed in the two side walls respectively, and the pivot shaft has two ends passing through the two pivoting holes respectively.

14. The refrigerating apparatus according to claim 13 , wherein the limiting structure comprises:
a first limiting piece disposed to the first hinge; and
a second limiting piece disposed to the second hinge and cooperating with the first limiting piece so that the second hinge pivots about the pivot shaft from 0° to 90° relative to the first hinge.

15. The refrigerating apparatus according to claim 14 , wherein the first limiting piece is configured to be a limiting hole and two limiting holes are provided in the two side walls respectively, and the second limiting piece is configured to be a limiting column and the limiting column has two ends passing through the two limiting holes respectively.

16. The refrigerating apparatus according to claim 15 , wherein the limiting hole is configured to be an arc hole and the limiting hole is arranged coaxially with the pivot shaft.

17. The refrigerating apparatus according to claim 15 , wherein a supporting structure is disposed between the first hinge and the second hinge, and the supporting structure comprises:
a spring having a first end away from the limiting column connected into the first hinge;
a supporting piece having a first end penetrating the spring and a second end connected with the limiting column; and
a supporting plate disposed onto the supporting piece and having a side surface adjacent to the spring abutting against a second end of the spring adjacent to the limiting column.

18. The refrigerating apparatus according to claim 1 , wherein a plurality of light assemblies is arranged on the door body and spaced apart from one another.
