Description

Title Fuel Energy Saving Food Cooker and Water Heater Arrangement Cross Reference of Related Application This is a Continuation-In-Part application of a non-provisional application having an application number 12/308,869 and a filing date of 12/24/2008.

Background of the Present Invention Field of Invention This present invention relates to a water heater, and more particularly to a water heater which is capable of heating up an amount of water by an excessive heat from a food cooking apparatus, such as an oil fryer, such that the water heater of the present invention is an environmental-friendly and a fuel energy saving device.

Description of Related Arts Many people like to eat fried foods because of its tastes and favorites.
Therefore, more and more food companies and restaurant provide fried food on the market. In order to achieve the fried food, those companies and restaurant need to use oil cooker or deep fryer to fry a huge amount of food. When frying the food, the oil cooker usually generates huge amount of heat and steam. And then the steam is usually discharged by the exhaust. Once the temperature of steam is too high, the exhaust channel will be overheated and broken very easily. As a result, the exhaust channel is needed to maintained, repaired, or replaced frequency. In addition, the steam is guided to exhaust directly to the environment. Therefore, the steam not only causes air pollution, but also is a waste of thermal.

On the other hand, as everyone knows, the water heater is an essential equipment in restaurants not only providing hot water, hot soups or drinks for their customers, but also forming a cooking apparatus to cook the food. Therefore, people have invented various kinds of heater to heat water and keep the water at a predetermined temperature. The size of the water heater is usually huge to fulfill the hot water demand for the restaurant.

In order to heat up the water from room temperature to around 90 C, the water heater has to consume huge amount of energy, such as gas or electric. On the other hand, since the water conducts and radiates its heat, the water temperature is kept decreasing at the same time. The water heater not only needs to heat water at high temperature, but also needs to keep it warm. For example, if the user wants to heat and keep 100 gallons of water at 90 C for 24 hours, a predetermined power is the minimum electrical energy to be consumed. Not to mention if the water heater is not an energy saving device, it consumes more energy to maintain water at high temperature. To sum up, the heat output from the oil cooker and the energy transform and heat input for the water heater at the same room are a big waste of thermal energy.

Summary of the Present Invention The major object of the present invention is to provide a fuel energy saving cooker and water heater arrangement, which has a simple structure and design.
It fully utilizes the heat generated by an oil cooker for heating up the water in the water tank so as to save energy, reduce exhaust, and protect the environment. Furthermore, the water heater can protect the exhaust channel of the oil cooker from being overheated or burnt by the steam.

Another object of the present invention is to provide a fuel energy saving cooker and water heater arrangement, which is designed to assure its operation safety.

Another object of the present invention is to provide a fuel energy saving cooker and water heater arrangement, wherein the fuel energy saving cooker and water heater arrangement combines the fuel energy saving cooker and water heater arrangement into a unity in such a manner that the volume of the whole appliance is much smaller and the material cost of the appliance is much lower either.

Accordingly, in order to accomplish the above object, the present invention provides a fuel energy saving cooker and a water heater arrangement wherein the heat collecting tank comprises an outer tank body and an inner tank body spacedly supported within the outer tank body to define the water chamber between the outer tank body and the inner tank body and to form the heat chamber within the inner tank body in such a manner that when the excessive heat passes through the heat chamber within the inner tank body, the water containing within the water chamber is heated up through the inner tank body.

The present invention further provides a fuel saving water heater for incorporating with a food cooking apparatus, comprising a heat collecting tank and a water guider.

A heat collecting tank has a heat chamber and a bottom heat energy inlet communicating with the heat chamber for operatively connecting to the food cooking apparatus to guide the excessive heat from the food cooking apparatus to the heat chamber.

A water guider is thermally communicated with the heat chamber, having a water chamber, a water outlet communicating with the water chamber, and a water inlet for operatively connecting to a water source, wherein when a water flow is guided to pass through the water chamber from the water inlet to the water outlet, the water flow is heated by the excessive heat therewithin at a predetermined water temperature.

The steam at a relatively high temperature produced by the oil cooker is guided to flow from food cooking apparatus to the heat chamber through the heat inlet. After the heat exchange between the water in the water tank and the steam at the heat chamber, the temperature of the steam will be dramatically dropped and the steam will then be discharged to the environment through upper heat outlet. The present invention utilizes the excessive heat from the oil cooker to heat the water in the water tank to minimize the use of other water heating apparatus so as to save the energy to heat the water and to decrease the temperature of the steam before the steam is discharged to the environment.
Therefore, the water heater of the present invention is an environmental-friendly and an energy saving device. In addition, the present invention can protect the exhaust channel of the oil cooker from being overheated or burnt by the steam since the steam is cooled down after the heat exchange within the heat chamber.

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.

As shown in Figs. 5 to 7 of the drawings, a fuel saving water heater for incorporating with the food cooking apparatus 1OA according to a second embodiment is illustrated, wherein the fuel saving water heater comprises a heat collecting tank 21A and a water guider 30A. The food cooking apparatus 10A comprises a heat source adapted for generating heat energy with a relatively high temperature for cooking food and outputting an excessive heat during operation.

According to the second embodiment, a heat collecting tank 21A has a heat chamber 211A and a bottom heat energy inlet 212A communicating with the heat chamber 211 A for operatively connecting to the food cooking apparatus I OA to guide the excessive heat from the food cooking apparatus 10A to the heat chamber 211A.
Accordingly, the food cooking apparatus 10A can be an oil type deep fryer, oven, electric stove, or gas stove in which they are commonly utilized in the kitchen.

The water guider 30A, which is thermally communicated with the heat chamber 211A, has a water chamber 5A, a water outlet 301A communicating with the water chamber 5A, and a water inlet 302A for operatively connecting to a water source 40A, wherein when a water flow is guided to pass through the water chamber 5A from the water inlet 302A to the water outlet 301A, water flow is heated by the excessive heat therewithin at a predetermined water temperature. Accordingly, when the water passes into the water chamber 5A through the water inlet 302A, the water is heated by the excessive heat within the heat chamber 211A. In other words, the water chamber 5A and the heat chamber 211 A are thermally communicated with each other for heat exchange so as to heat up the water within the water chamber 5A.

Accordingly, the heat collecting tank 21 A has a rectangular shape defining a top wall 24A, a front wall 23A, a rear wall 32A, two sidewalls 33A, and a base wall 34A, wherein the heat chamber 5A is formed therewithin. For better installation of the water heater, a screw hole 35A is provided at the front wall 23A of the heat collecting tank 21 A
thereof to secure the bottom heat energy inlet 212A with the outlet of the food cooking apparatus 10A. For security and safety purpose, a safety valve 303A is provided for the water chamber 5A. The heat collecting tank 21A further has a heat releasing outlet 213A
formed at the top wall 24A for operatively connecting to a chimney of the food cooking apparatus 10A. Therefore, the excessive heat will pass through the heat chamber 5A
through the heat energy inlet 212A and will exit to the chimney of the food cooking apparatus 1OA through the heat releasing outlet 213A.
Referring to Fig. 7 of the drawings, the heat collecting tank 21A comprises an outer tank body 214A and an inner tank body 215A spacedly supported within the outer tank body 214A to define the water chamber 5A between the outer tank body 214A
and the inner tank body 215A and to form the heat chamber 211 A within the inner tank body 215A in such a manner that when excessive heat passes through the heat chamber within the inner tank body 215A, water containing within the water chamber 5A
is heated up through the inner tank body 215A.

It is worth to mention that the outer tank body 214A is made of thermally insulated material for effectively maintaining excessive heat to heat up the water within the water chamber 5A, while the inner tank body 215A is made of thermally conductive material for effectively conducting excessive heat from the heat chamber 211 A
to the water chamber 5A.

Referring to Fig. 6 of the drawings, the water inlet 302A is formed at a bottom portion of the outer tank body 214A and the water outlet 301A is formed at an upper portion of the outer tank body 214A to communicate with the water chamber 5A.
Therefore, the water is filled up in the water chamber 5A from bottom to top for being effectively heated up by the excessive heat.

According to the preferred embodiment as shown in Fig. 8, the fuel saving water heater further comprises at least an elongated water tube 216A extended between two sidewalls of the inner tank body 215A respectively through the heat chamber 211A for heating up the water within the water tube 216A when the water passing through the water tube 216A from one side of the water chamber 5A to another side thereof.
It is worth to mention that water can freely flow within the water chamber 5A from one side to another side through the water tube 216A such that the excessive heat can be evenly distributed to heat up the water at uniform temperature within the water chamber 5A.

The fuel saving water heater further comprise a plurality of conductive fins 217A spacedly supported along the water tube 216A within the heat chamber 211 A, wherein the conductive fins 217A are adapted for thermally conducting the excessive heat within the heat chamber 21 IA to the water tube 216A so as to effectively heat up the water when the water passes along the water tube 216A.
Referring to Fig. 8 of the drawings, the heat collecting tank 21A further comprises a supplemental heater 218A supported within the water chamber 5A for generating additional heat energy therewithin for heating up the water passing through the water chamber 5A, and a water temperature sensor 219A operatively linked to the supplemental heater 218A to activate the supplemental heater 218A when the water temperature of the water is below a preset temperature.

The water temperature sensor 219A is adapted to detect the water temperature of the water pipe 303 A. When the water is not heated up within the water pipe 303A by the excessive heat at a predetermined temperature, the water temperature sensor 219A
will automatically activate the supplemental heater 218A for heat generation to heat up the water until the water temperature of the water within the water pipe 303A
reaches the predetermined temperature, so as to ensure the hot water flowing out at the water outlet 301A. Accordingly, the water is preferably heated up around 90 C.

For example, the temperature sensor 219A, which is connected between the supplemental heater 218A and the water guider 30A, comprises a preset temperature controller 221 A within the temperature sensor 219A with 90 C for turning on and cutting off the power supply of the supplemental heater 218A. The temperature sensor monitors the temperature of water in the water guider 30A in real-time. For example, when the temperature of water is lower than the preset temperature 90 C, the supplemental heater 218A turns on the power supply of the supplemental heater 218A to heat up water till 90 C. On the contrary, once the temperature of water is higher than the preset temperature 95 C, the supplemental heater 218A automatically deactivates the power switch of the supplemental heater 218A. Moreover, the user is able to set the saving energy mode other than the office hour to turns off the supplemental heater 218A
for save more energy.

In other words, when the water temperature within the water guider 30A
increases from the room temperature to 70 C as an example by the excessive heat, the temperature sensor will automatically activate the supplemental heater 218A to heat up the water from 70 C to 90 C. Therefore, the energy consumed by the supplemental heater 218A will be substantially reduced in comparison with the conventional water heater for heating up the water from room temperature to 90 C.

The heat collecting tank 21A further comprises a plurality of reinforcing ribs 220A spacedly supported between the outer tank body 214A and the inner tank body 215A to enhance the strength of the heat collecting tank 21A. The reinforcing ribs 220A
can be embodied as an expandable element such that when the excessive heat is accumulated within the heat chamber 211 A, the heat collecting tank 21 A can be slightly self-expanded correspondingly to prevent the damage of the heat collecting tank 21A by means of over-expansion. Accordingly, the reinforcing ribs 220A are indented within the walls of the heat collecting tank 21A and are capable of improving strength of the tank body and to extend the life span of the tank body.
