Abstract

A drinking water warming and heating device, comprising a housing having a storage chamber inside thereof and a water circulating space set therebetween. Inside the space is a partition which divides the space into an inner and an outer water circulating space, and mounting plates connected perpendicularly on either side of the partition and extending between the housing and the chamber, the plates dividing the inner and outer water circulating spaces into vertical channels. The water circulating passage has one end connectable to the water outlet port of the engine of a motor vehicle and an opposite end connectable to the water tank of said motor vehicle permitting waste heat from engine cooling water to make heat exchange with drinking water in the water storage chamber. An electric heating element in the storage chamber is connected to the battery power supply of the motor vehicle to heat warmed-up drinking water to boil.

Claims

1. A drinking water warming and heating device comprising:

a housing having walls defining an interior space therein;

a storage chamber having walls located inside said space in spaced relationship to said housing walls to define a water circulating space between said chamber and said housing;

a partition set in said housing in said water circulating space to divide said water circulating space into an inner water circulating space and an outer water circulating space, wherein said partition extends vertically in said water circulating space;

a mounting means connected to said partition and located in said water circulating space for mounting said partition spaced between said housing walls and said chamber walls, and wherein and mounting means comprises vertically extending plates located in said outer circulating space and connected between said partition and said housing walls;

an engine cooling water intake port in communication with said inner space and connectable to an engine of a motor vehicle having a water tank, and said intake port directing hot engine cooling water into said inner water circulating space; and

an engine cooling water outlet port in communication with said outer water circulating space and connectable to the water tank of the motor vehicle to guide the hot engine cooling water from said outer water circulating space to the water tank;

said inner water circulating space and said outer water circulating space being in communication with each other at a location remote from said inlet and outlet ports such that the cooling water circulates from said inlet port through said inner space, into said outer space, and thence out said outlet port.

2. The device claimed in claim 1 wherein said plates divide said outer water circulating space into a plurality of vertical water channels.

3. The device claimed in claim 1 wherein said mounting means further comprises vertically extending plates located in said inner water circulating space and connected between said partition and said chamber walls.

4. The device claimed in claim 3 wherein said plates extend perpendicularly between said partition and said housing walls and between said partition and said chamber walls.

5. The device as claimed in claim 4 wherein at least some of said plates in said inner water circulating space are coplanar with corresponding ones of said plates in said outer water circulating space.

6. The device as claimed in claim 1 wherein said inner water circulating space and said outer water circulating space are in communication with each other at the top portion of said housing, and said inlet and outlet ports are located at the bottom portion of said housing.
