Abstract

The heat insulation door of a refrigeration appliance has a door body. The door body includes a heat insulation glass module with at least two layers of glass plates disposed with an interval; a doorframe that surrounds the heat insulation glass module and that includes a rear frame portion located at the back of the heat insulation glass module, and a door sealing strip connected to the back of the rear frame portion. The doorframe further has an enclosed heat insulation cavity, wherein the heat insulation cavity is located between the door sealing strip and the heat insulation glass module along a front-to-rear direction or located on the inner side of the door sealing strip in a direction parallel to the door body. The present invention can improve the heat insulation effect of the refrigeration appliance.

First claim

The invention claimed is:

1. A heat insulation door for a refrigeration appliance, the heat insulation door comprising:
a door body, the door body including:
a heat insulation glass module having at least two glass plates disposed at a spacing distance defining an interval;
a first sealing portion disposed between edges of the adjacent glass plates for defining an enclosed heat insulation layer between the glass plates;
a doorframe that surrounds the heat insulation glass module, the doorframe being divided into a rear frame portion located at the back of the heat insulation glass module along a front-to-rear direction of the door and a side frame portion located outside a peripheral surface of the heat insulation glass module;
the rear frame portion having a mounting slot formed therein, the slot being inward of the first sealing portion relative to an edge of the door panel in a direction parallel to the door body;
a door sealing strip mounting in the mounting slot and connected to the back of the rear frame portion;
at least one enclosed heat insulation cavity separate from the mounting slot, the heat insulation cavity having a completely enclosed cross section and being adjacent the mounting slot inwardly of the mounting slot in a direction parallel to a main extent of the door body, the heat insulation cavity being provided internally in the rear frame portion.

2. The heat insulation door according to claim 1 , wherein at least one heat insulation cavity is formed between the rear frame portion and the door body.

3. The heat insulation door according to claim 2 , wherein there is a gap between the rear frame portion and the door body, and the heat insulation cavity is located in the gap.

4. The heat insulation door according to claim 3 , wherein along a direction parallel to the door body, an inner side of the rear frame portion and the door body are bonded by glue or are sealed by way of a sealing member, and an outer side of the rear frame portion and the door body are bonded by glue or are sealed by way of a sealing member.

5. The heat insulation door according to claim 1 , wherein the heat insulation glass module is a vacuum glass module and/or a hollow glass module.

6. The heat insulation door according to claim 1 , wherein the door body further comprises:
a front door panel located in front of the heat insulation glass module disposed with an interval from the heat insulation glass module; and
a second sealing portion is disposed between the edge of the heat insulation glass module and the front door panel to form an enclosed heat insulation layer between the front door panel and the heat insulation glass module.

7. The heat insulation door according to claim 6 , wherein in a width and/or length direction of the door body, the front door panel has a protruding portion that extends out of the edge of the heat insulation glass module.

8. The heat insulation door according to claim 7 , wherein the protruding portion completely shields the doorframe along the front-to-rear direction of the door.

9. The heat insulation door according to claim 7 , wherein the doorframe further comprises:
a first cooperative wall, located in front of the rear frame portion and at the back of the protruding portion, wherein the first cooperative wall is connected to the protruding portion;
a second cooperative wall, disposed at the rear frame portion towards the heat insulation glass module; and
a connecting wall that connects the first cooperative wall and the second cooperative wall along the front-to-rear direction, and the heat insulation glass module is located between the first cooperative wall and the second cooperative wall.

10. The heat insulation door according to claim 9 , wherein the heat insulation glass module is directly or indirectly connected to the second cooperative wall.

11. The heat insulation door according to claim 6 , wherein the front door panel is a colorful crystal glass plate.

12. A refrigeration appliance, comprising an insulation door according to claim 1 .

13. The heat insulation door according to claim 1 , which further comprises an enclosed heat insulation cavity formed between the sealing strip of the door and the heat insulation glass module along a front-to-rear direction.

14. A heat insulation door for a refrigeration appliance, the heat insulation door comprising:
a door body, the door body including:
a heat insulation glass module having at least two glass plates disposed at a spacing distance defining an interval;
a first sealing portion disposed between edges of the adjacent glass plates for forming an enclosed heat insulation layer between the glass plates;
a front door panel located in front of the heat insulation glass module disposed with an interval from the heat insulation glass module; and
a second sealing portion disposed between the edge of the heat insulation glass module and the front door panel for forming an enclosed heat insulation layer between the front door panel and the heat insulation glass module;
a doorframe that surrounds the heat insulation glass module, the doorframe being divided into a rear frame portion located at the back of the heat insulation glass module along a front-to-rear direction of the door and a side frame portion located outside a peripheral surface of the heat insulation glass module;
the rear frame portion having a mounting slot formed therein, the slot being inward of the first sealing portion relative to an edge of the door panel in a direction parallel to the door body;
a door sealing strip mounting in the mounting slot and connected to the back of the rear frame portion;
at least one enclosed heat insulation cavity separate from the mounting slot, the heat insulation cavity having a completely enclosed cross section and being adjacent the mounting slot inwardly of the mounting slot in a direction parallel to a main extent of the door body, the heat insulation cavity being provided internally in the rear frame portion;
the at least one heat insulation cavity being located on an inner side of the second sealing portion in a direction parallel to the door body.

15. A heat insulation door for a refrigeration appliance, the heat insulation door comprising:
a door body, the door body including:
a heat insulation glass module having at least two glass plates disposed at a spacing distance defining an interval;
a first sealing portion disposed between edges of the adjacent glass plates for forming an enclosed heat insulation layer between the glass plates;
a front door panel located in front of the heat insulation glass module disposed with an interval from the heat insulation glass module; and
a second sealing portion disposed between the edge of the heat insulation glass module and the front door panel for forming an enclosed heat insulation layer between the front door panel and the heat insulation glass module;
a doorframe that surrounds the heat insulation glass module, the doorframe being divided into a rear frame portion located at the back of the heat insulation glass module along a front-to-rear direction of the door and a side frame portion located outside a peripheral surface of the heat insulation glass module;
