Description

a combustion furnace

technical field

The invention relates to kitchen utensils, in particular to a combustion furnace.

Background technique

In the field of kitchen utensils, there are usually gas stoves, induction cookers, and electric stoves for liquid heating. The cost of induction stoves and electric stoves is high, and they are usually suitable for families or individuals.

At present, the structure of gas stoves mostly includes air inlet, air inlet pipe, air outlet, igniter, etc., that is, an open flame is used to heat the pot to be heated, and the combustion furnace used in restaurants is usually used for cooking soup or porridge. After the open fire heats the pot, the liquid in the pot is heated after the pot is heated. First, the heat transfer efficiency of the open fire to the pot is low, and the time of cooking soup or porridge is long, and the heat loss is large; When the heating temperature is high (much higher than 100°C), the water for making soup or porridge will vaporize instantly after contact with it, so that the calcium carbonate and magnesium carbonate in the water will precipitate out, and the scale in the pot will adhere to the wall and bottom of the pot, which will not only cause heating efficiency Reduced, but also affect the health of diners.

Contents of the invention

The object of the present invention is to provide a combustion furnace to solve the problems raised in the background art above.

To achieve the above object, the present invention provides the following technical solutions:

A combustion furnace, including a burner, a heating furnace and a pot body. The burner includes a combustion cylinder, a fan, a corrugated pipe, and an igniter. One end of the igniter communicates with the intake pipe, and the other end of the igniter is connected to the fan through the corrugated pipe. , the corrugated pipe is set in the combustion tube, the heating furnace is fixed on the combustion tube, the pot body is set in the heating furnace, and the contact part between the pot body and the heating furnace is sealed by a sealing ring; when cooking soup or porridge, natural gas or liquefied petroleum gas is ignited Combustion occurs in the device, the fan works, natural gas or liquefied gas is sucked into the bellows and burns, the water medium in the combustion tube absorbs the heat transferred by the bellows and gasifies, and the water vapor rises into the heating furnace, thereby contacting the pot , the water vapor liquefies and transfers heat to the pot, and the pot heats the food to be cooked in it; since the maximum temperature of water vapor is 100°C, liquefaction and heat conduction will only occur when the temperature of the pot is lower than 100°C, which makes The temperature of the water in the pot will not exceed 100°C, so that scale will not be generated; meanwhile, the present invention uses the bellows to cause the combustion reaction to occur in the water medium, and regasifies the pot to heat the pot, so that the heat loss is low.

The invention is further improved, the bottom surface of the pot body is a spherical surface, which increases the heating area of the pot body and improves the heat utilization rate.

The invention is further improved. The heating furnace and the pot body are both cylindrical, and the pot body and the heating furnace are detachably connected, which is convenient for maintenance and replacement of parts.

The present invention is further improved, and further includes a pressure relief valve and a check valve, which are respectively arranged on the heating furnace, so as to prevent explosion caused by excessive water vapor in the heating furnace and eliminate potential safety hazards.

The invention is further improved, and further includes a liquid level and temperature measuring integrated meter, one end of the liquid level and temperature measuring integrated meter extends into the combustion cylinder to monitor the temperature and liquid volume in the combustion cylinder in real time.

The present invention is further improved, and also includes a pot body outlet pipe and a burner outlet pipe, one end of the burner outlet pipe communicates with the combustion cylinder, one end of the pot body outlet pipe communicates with the bottom of the pot body, and the other end of the pot body outlet pipe extends out of the furnace.

The combustion furnace proposed by the present invention creatively uses bellows to generate the combustion reaction inside the water medium, and then uses water vapor to heat the pot. Although it is the second heat transfer, the first heat transfer is basically zero. loss, reducing heat loss and saving energy; since the water medium in the pot will not gasify during the combustion process, there will be basically no scale in the pot, which is especially important for commercial use, eliminating the need to remove scale The work ensures the eating health of diners, and has great promotion and application value.
