The utility model is a multifunctional energy-saving cooker adaptable to various heat sources.

Cooking utensils are indispensable utensils for human life. According to we consult relevant data and carry out investigation and understand, there is not yet a kind of standing cooking utensil with multi-purpose and adaptation to multiple heat sources in my country. For example: the widely used steam cabinet can only steam food, and it must be used in conjunction with the domestic boiler. There are many supporting facilities and large energy consumption; the far-infrared food oven overcomes the shortcomings of the steam cabinet, but it can only bake food; the microwave oven has a fast heating speed and high thermal efficiency, but it is not suitable for processing rice, and its cost is high. Now it is limited to a few families. use.

In order to solve the problem that one device can not be used more than one device and one device can only use one energy source, the inventor has finally completed the utility model through serious research to solve the problems that the conventional cooking utensils exist.

The purpose of this utility model is to provide a kind of steaming, boiling, grilling food and hot water using waste heat, which can not only use electricity, but also use solid fuel (such as coal), liquid fuel (such as waste oil), gas fuel ( For example: biogas, coal gas, liquefied petroleum gas) cooking utensils that provide heat energy; another purpose of the utility model is to provide a cooking utensil that can automatically control temperature, pressure, time and heat preservation.

The utility model is realized in this way: an oil jacket is installed in a cabinet with good mechanical strength and heat insulation performance, and the oil jacket contains a liquid-phase high-temperature heat carrier (such as heat-conducting oil), and the lower and side parts of the oil jacket Equipped with several sets of finned heating elements. The electric heating element converts electric energy into heat energy, and quickly transfers the heat energy to various parts of the cabinet inner cavity through the heat transfer oil, so that the food placed in the cabinet inner cavity absorbs heat and cooks. When other fuels are used as heat energy, the heat conduction oil in the oil jacket is drawn out through the pipeline, heated by the coil heater and injected into the oil jacket, so that the inner cavity of the cooker cabinet can obtain heat energy to achieve the purpose of cooking food.

The utility model adopts the temperature control element and the temperature control instrument to adjust the output electric power; adopts the temperature control element, the temperature control instrument and the electromagnetic valve to adjust the damper of the solid fuel combustion chamber or the flow of the liquid and gas fuel to control the firepower to achieve automatic temperature control and heat preservation. Use the time relay to control the working time of the cooker. Use the automatic air release valve to regulate the air pressure in the cooker cabinet. Therefore, it is convenient to use, safe and reliable, and cooker cabinets with different specifications can be designed and manufactured according to the food supply.

The internal structure of the utility model will be further described in detail below in conjunction with the accompanying drawings. The circuit of program control principle is simple and will not be described in detail in this manual.

Fig. 1 is an axonometric view of a specific form of the utility model;

Fig. 2 is a structural principle diagram of a specific form of the utility model.

Referring to Fig. 2, the four sides (including the cabinet door) inside the cooker cabinet shell (1) are provided with a thermal insulation layer (2) for heat preservation. An oil jacket (3) is arranged close to the heat insulation layer (2) (excluding the cabinet door) to store heat transfer oil. Inject the required heat transfer oil from the oil jacket (3) of the oil injection hole (13), and the oil storage capacity can be measured by the oil mark (12). The lower and side parts of the oil jacket (3) are equipped with multiple sets of electric heating elements (4) and (6) with metal fins, and there are multiple sets of heat transfer tubes (8) and expansion tanks ( 11), metal cooling coil (14) and oil and gas holes (15).

When electricity is used as the energy source, close the output valve (25) and input valve (21) of the heat transfer oil of the cooker cabinet; the electric energy is converted into heat energy through the electric heating elements (4), (6), so that the oil jacket (3) and the heat transfer tube ( 8) The oil inside is heated, and heat is transferred through the wall of the inner cavity (10) of the cooker cabinet and the wall of the heat transfer tube (8), so that the inner cavity (10) of the cooker is heated rapidly and evenly. The food material placed in the inner cavity of the cooker absorbs heat and cooks. When steaming food, place the food with the food basin (9) or the food rack (7), and pour the required amount of water into the steam water tank (5) at the bottom of the cabinet cavity (10). After heating, the inner cavity of the cooker can not only be heated evenly And it is full of water vapor to achieve the purpose of steaming food. When cooking and grilling food, drain the water in the steam water tank (5), use the food bowl (9) to hold the food and water when cooking, and use the food rack (7) to place the food when baking food , Because the inner cavity of the cooker cabinet can be heated evenly, as long as the processing temperature and time are adjusted according to the needs, the food can be cooked or baked.

In order to make the cooking utensil cabinet inner chamber (10) maintain a certain pressure and prevent overpressure when processing food, an automatic air release valve (16) is installed on the upper end of the cabinet to ensure safety.

The waste heat water heater consists of a water tank (18) at the upper end of the cooker cabinet, a cooling coil (14), an oil and gas hole (15), an automatic air release valve (16), a water injection hole (17), a water level gauge (19) and a water discharge valve (20) . Its function is: First, reduce the surface area of the heat transfer oil in contact with the air after heating and reduce the surface temperature of the heat transfer oil in contact with the air, and improve the use efficiency and service life of the heat transfer oil. (Because the heat transfer oil expands when heated, it enters the lower part of the heat dissipation coil (14), so the surface area of the heat transfer oil in contact with the air is very small, and the water in the water tank (18) takes away the oil and gas of the heat transfer oil in the heat dissipation coil (14) The waste heat makes the surface temperature of the heat transfer oil in contact with the air low. The second is to use the heat transfer oil to discharge oil gas after being heated and the waste heat hot water brought by the automatic steam release valve (16).

When processing food with other fuels, open the heat transfer oil output valve (25) and input valve (21) of the cooker cabinet, and start the oil pump (24) with a backup power supply (such as a storage battery). The heat transfer oil in the oil jacket (3) flows through the oil delivery pipe (23) from the output valve (25), flows through the coil heater (45), absorbs heat, and then injects oil through the oil delivery pipe (22) from the input valve (21) cover (3), so that the heat conduction oil is circulated and heated. The heat energy carried by the heat transfer oil is absorbed by the food in the inner cavity of the cooker cabinet to cause heat.

This cooker is equipped with three kinds of burners which are easy to disassemble, and only one of them is needed each time in actual use. The first is a solid fuel combustion device, which is made up of a coal stove (28), a louver type damper (29) and an electromagnetic control valve (27); the second is a liquid fuel combustion device, which is composed of a liquid fuel spray nozzle ( 30), valve (31), flow control solenoid valve (32), oil pump (33), infusion pipe (34) and liquid storage barrel (35); the third is a gas fuel combustion device, which is composed of a gas storage cylinder (36), air pipe (37), flow control solenoid valve (38), valve (39), gas fuel burner (40). When in use, any one of coal stove (28), liquid fuel spray nozzle (30), and gas fuel burner (40) can be packed into combustion chamber (26) to burn fuel.
