Abstract

Provided are a housing assembly and a water heater. The housing assembly includes a bottom plate assembly and an outer housing. The outer housing is provided with a hooking fitting portion, the bottom plate assembly includes: a base and a supporting portion, a crimping space for positioning the outer housing is formed between at least portion of the supporting portion and the base. The hooking fitting portion is hooked with the crimping space.

First claim

What is claimed is:

1. A housing assembly, comprising: a bottom plate assembly and an outer housing, the outer housing is provided with a hooking fitting portion, the bottom plate assembly comprises: a base; and a supporting portion, a crimping space for positioning the outer housing is formed between the supporting portion and the base, the hooking fitting portion is hooked with the crimping space, the base is provided with a groove for accommodating the outer housing, a slot wall of the groove is used as a stopping surface for preventing the outer housing from slipping, the supporting portion is provided with a connection bump extended toward the base, the connection bump is hooked with the hooking fitting portion of the outer housing, the supporting portion is provided with a crimping end and a supporting end, a bottom end of the supporting end is level to a bottom end of the base, the connection bump is arranged on the crimping end, the base is an annular structure, the supporting end is located inside an inner annular surface of the base;
wherein the hooking fitting portion is a hook that is integral to an end of the outer housing, and extending from the end of the outer housing, the hook is hooked with the connection bump.

2. The housing assembly as claimed in claim 1 , wherein the stopping surface is arranged in an inclined way with respect to a bottom surface of the groove to guide when installing the outer housing.

3. The housing assembly as claimed in claim 1 , wherein the crimping space is formed between the connection bump and the slot wall of the groove.

4. The housing assembly as claimed in claim 1 , wherein a slot wall surface of the groove opposite to the stopping surface is a supporting surface, a height of the supporting surface is greater than a height of the connection bump to support the supporting portion.

5. The housing assembly as claimed in claim 1 , wherein a positive projection of the supporting portion on the bottom plate assembly comprises a first side projected by the supporting end and a second side projected by the crimping end, and the first side and the second side have the same radius of curvature.

6. The housing assembly as claimed in claim 1 , wherein the supporting portion is further provided with a first positioning structure, and the base is further provided with a second positioning structure that is positioned and matched with the first positioning structure.

7. The housing assembly as claimed in claim 6 , wherein the first positioning structure is a positioning convex column, the second positioning structure is a positioning hole, the positioning convex column is inserted in the positioning hole.

8. The housing assembly as claimed in claim 1 , wherein the inner annular surface of the base is provided with a convex rib, the supporting portion is provided with a recess portion that is adapted with the convex rib in shape.

9. The housing assembly as claimed in claim 1 , wherein the housing assembly is a water tank.

10. A water heater, comprising the housing assembly as claimed in claim 1 .

11. The housing assembly as claimed in claim 10 , wherein the base is provided with a groove for accommodating the outer housing, a slot wall of the groove is used as a stopping surface for preventing the outer housing from slipping.

12. The housing assembly as claimed in claim 11 , wherein the stopping surface is arranged in an inclined way with respect to a bottom surface of the groove to guide when installing the outer housing.

13. The housing assembly as claimed in claim 11 , wherein the supporting portion is provided with a connection bump extended toward the base, the connection bump is hooked with the hooking fitting portion of the outer housing.

14. The housing assembly as claimed in claim 13 , wherein the crimping space is formed between the connection bump and the slot wall of the groove.

15. The housing assembly as claimed in claim 13 , wherein the hooking fitting portion is a hook on an end of the outer housing, the hook is hooked with the connection bump.

16. The housing assembly as claimed in claim 13 , wherein a slot wall surface of the groove opposite to the stopping surface is a supporting surface, a height of the supporting surface is greater than a height of the connection bump to support the supporting portion.
