1. Field of Invention
This present invention relates to a water heater use in cooking stove, and more particularly to an energy saving stove water heater which is capable of heating up water by means of the cooking stove.
2. Description of Related Arts
The boundary wall of the stove cavity of conventional cooking stove used in family or restaurant is constructed with fireproof bricks. Such stove cavity structure of the traditional cooking stove can't efficiently utilize the excessive heat during operation. The fireproof bricks need to be replaced frequency after a period of use. Moreover, it is inconvenient to assemble and use.
An object of the present invention is to provide an energy saving stove water heater, which has a simple structure and is convenient for set up and use. Also, it can achieve the goal of reducing exhaust and saving energy.
Accordingly, in order to accomplish the above object, the present invention provides an energy saving stove water heater which is constructed by an outer tank body, an inner tank body, a top panel and a bottom panel. The inner tank body and the outer tank body define a sealed water chamber therebetween. The inner and outer tank bodies are provided with a channel extending through the water chamber for disposing the fuel line.
The energy saving stove water heater is capable of heating up water by fully utilizing the excessive heat from a cooking stove such that there is no need to consume any other energy to have hot water to save energy. In addition, the independent water heater has a compact structure that is easier for set up and usage.
These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
Referring to
In order to prevent the incoming cool water from the water inlet 7 from immediately exiting at the water outlet 8, an isolated wall 9 is built between the water inlet 7 and the water outlet 8 in the water chamber 5 for separating incoming cool water and the exiting heated water within the water chamber 5.
For security and safety purpose, a safety valve 10 is installed to the outer tank body 2. The safety valve is communicated with the water chamber 5 for releasing the internal pressure and steam within the water chamber 5 while the water being heated up therein.
The energy saving stove water heater further comprises an electric heater 11 installed near the water outlet 8 within the water chamber 5 for generating electrical heat to heat up the water in the water chamber 5, wherein when the temperature of water is detected lower than the usage requirement, the electric heater 11 is switched to heat up the water to be exited through the water outlet 8 so as to ensure the temperature of the water supply from the stove water heater of the present invention.
As a reasonable design, the inner and outer tank bodies 1, 2 are provided with a ventilation channel 12 extending through the water chamber 5, wherein the ventilation channel 12 can be extended to the bottom panel 4 in a vertical direction to form a groove to make a detour with the exhaust line of the stove.
In view of above, a stove can be installed inside the cavity surrounded by the inner tank body 1 while the fuel pipe of the stove extends through the channel 6 and the exhaust line passes through the ventilation channel 12, not shown in Figures. In other words, the boundary bricks of the traditional stove are replaced by the stove water heater of the present invention as shown in

Referring to
According to the fourth embodiment as shown in
It is worth to mentioning that a cross section of the inner tank body 1 of the energy saving stove water heating is in circular shape.
In view of above, the energy saving stove water heater of the present invention is capable of heating up water flowing through the water chamber by fully utilizing the excessive heat from the cooking stove such that there is no need to consume any other energy to have hot water. Therefore, the energy saving stove water heater of the present invention is an energy saving device. In addition, the present invention is an individual and compact structure that is easier for assemble and usage.
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
It will thus be seen that the objects of the present invention have been fully and effectively accomplished. The embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
