Description

Chinese food gas cooking stove
Technical Field
The invention relates to a gas stove, in particular to an improved gas stove for stir-frying Chinese food.
Background
In recent years, as the standard of living of people increases, the number of household cookers has rapidly increased, and is also increasing at a rate of about 7% per year. In the gas appliance market, a gas cooker has become one of kitchen appliances indispensable to homes, and has occupied a mainstream position. With the continuous research of different manufacturers on gas cookers, the problems caused by the inherent deficiency of the gas cooker design technology are more and more emphasized by research personnel, and the main technical problems are as follows: the national standard stipulates that the heat efficiency of the embedded gas cooker is more than 50%, the heat efficiency of the table type gas cooker is more than 55%, in the actual product development test, the actual test heat efficiency of the embedded type household gas cooker is between 50% and 54% on average (the completely premixed type combustion appliance adopts an infrared combustion principle or adopts a blowing mode to prevent external convection wind from influencing and accumulating heat energy, and the embedded type household gas cooker and the table type household gas cooker of the technology are not included), the heat efficiency is about five percent lower than the actual test heat efficiency of the table type household gas cooker on average, and the test comparison calculation shows that the heat loss of the table type household gas cooker is about nine percent higher than the average of the table type household gas cooker. Because of the limitation of the design structure, when the embedded gas cooker is actually combusted, the supplied air is always lower than that of the table household gas cooker, therefore, in order to ensure that the concentration of CO in the combustion flue gas does not exceed the standard, the height of the pot support is generally designed to be increased so as to be beneficial to the air supply, although the concentration of CO in the combustion flue gas does not exceed the standard, the thermal efficiency of the embedded gas cooker is difficult to reach the standard of the thermal efficiency of the table gas cooker, which is a development difficulty in the combustion technology.
Because Chinese food cooking usually adopts a frying and frying cooking mode, the requirement on the firepower of a gas stove is very high, and the gas stove capable of meeting the Chinese food cooking requirement is urgently needed in the market.

Detailed Description
The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.
As shown in the drawings, a gas range for chinese food cooking includes a burner 10, wherein the burner 10 is installed in a gas range housing 12, and pure air, which is not mixed with gas all around, flows through the burner in the direction of an arrow 14 in the gas range housing 12 so as to be heated by the flame of the burner. The burner 10 has a longitudinal burner housing 16 having an interior chamber 18 and main 20 and pilot 22 burner slots extending the length of the longitudinal burner housing 16. A main burner trough 20 and a pilot burner trough 22 are disposed in an upper surface 24 of the longitudinal burner housing 16 and communicate with the interior chamber 18. A flow-restricting duct 26 is also provided in the upper surface 24 of the longitudinal burner housing 16, through which duct 26 communication is possible between the inner chamber 18 and the pilot channel 22. Disposed in the main burner trough 20 and the pilot burner trough 22 are a main burner flame forming assembly 28 and a pilot burner flame forming assembly 30, respectively, which form main flame ports 32 and pilot flame ports 34, respectively. The inner chamber 18 is fed by a mixing duct 36 with a combustible air and gas mixture, called simply combustible mixture, which forms a main flame F and a pilot flame P respectively when ignited at the main flame port 32 and the pilot flame port 34. The inner chamber 18 is partially cylindrical about the burner axis x. The longitudinal burner housing 16 forms a combustible mixture channel which is closed at both ends by end caps 38, the end caps 38 being mounted on end flanges 42 of the longitudinal burner housing 16 and secured by a plurality of flange bolts 40. The longitudinal burner housing 16 is symmetrical with respect to a plane P, wherein the burner axis x lies on the cylindrical center line.
The burner adopted by the gas stove can greatly improve the flame efficiency, so the gas stove is very suitable for being used as a Chinese food gas stove. The combustible mixture supplied to the inner chamber 18 forms the main flame F and the pilot flame P, while any additional outside air or secondary combustion of the air is required.
In the actual cooking application, the air and the gas are premixed in a given ratio in a usual premixer (not shown in the figures of the present invention, but obvious to a person skilled in the art), and the mixture is conducted into said internal chamber 18 at a variable volumetric flow rate to maintain the respective desired flame. In actual production, the present invention selects an appropriate mixing ratio to obtain the optimum heat strength of the flame.
Further, the burner 10 also comprises an outer chamber 50, the outer chamber 50 being constituted by a casing 52 above the longitudinal burner housing 16. The housing 52 has two opposing end walls 54 and a peripheral wall 56. The peripheral wall 56 has a part-cylindrical portion 58 and a tangentially continuous planar portion 60. Wherein a part-cylindrical portion 58 is mounted on the end flange 42 of the longitudinal burner housing 16 and the other end flange screw 62 is fixed to the end flange 42 of the burner housing 16. The planar portion 60 extends upwardly and forms, with the end wall 54, an opening 64 to the outer chamber 50, the outer chamber opening 64 corresponding to the primary flame ports 32 and pilot flame ports 34. The end wall 54 of the casing 52, at the opposite end between the end flange 42 and the opening 64 of the longitudinal burner housing 16, partially closes the outer chamber 50; while the end flange 42 itself closes off the remainder of the outer chamber 50 at its end.
The lower end of the end wall 54 of the casing 52 is connected to a lower end plate 66, the lower end plate 66 being disposed between the end flange 42 and the end cap 38. Both ends of the peripheral wall 56 are fixed to the outer flange 70 by peripheral wall end screws 68. Between the upper surface 24 of the longitudinal burner housing 16 and the opening 64 is formed an air flow passage 72 of the outer chamber 50, which air flow passage 72 is open to the remainder 74 of the outer chamber 50 at both sides 76 and 78 of the upper surface 24, thereby forming a flow path. In this way, the depth of the air flow channel 72 of the outer chamber 50 is sufficient to shield the critical flame region of the burner directly from the passing air flow to be heated, i.e. to ensure stable combustion of the flame while preventing the flowing air from forming a certain vacuum region and thus extinguishing the flame; the gas stove is one of the main reasons that the famous flame-out is caused by increasing the gas flow or the flame efficiency in the cooking and frying process of the traditional Chinese food type gas stove.
The casing 52 is provided with a restriction groove 80 at a side opposite to the upper surface 24 of the longitudinal burner housing 16, the restriction groove 80 extending in the longitudinal direction of the outer chamber 50, and the gas flow passing through the restriction groove enters the outer chamber 50 after passing through the restriction groove. Due to the large volume of the outer chamber 50, the incoming airflow is significantly reduced in pressure and velocity, and as it enters the outer chamber 50, any turbulence that may be immediately created by the airflow will be largely buffered as it approaches the airflow passage 72, thereby smoothing the airflow entering the outer chamber after it passes through the airflow passage 72 and openings 64, thereby reducing the vacuum, but without adversely affecting the flame stability.
In actual production, this flowing air is delivered to a position closer to the base b of the pilot flame and the main flame F based on the above-described effects. To this end, the present invention provides 82 a location on the planar portion 60 near the base of the flame to enhance the above-described effect. The baffle 82 is secured to the planar portion 60 by baffle screws 84 and is spaced therefrom by baffle screws 84 secured to V-shaped spacing brackets 86 on the peripheral wall 56. The lower part of the circumferential wall 56 is in complementary cylindrical parts 88 and 90, which complementary cylindrical parts 88 and 90 are provided with longitudinal flanges 92 with a space between the longitudinal flanges 92 to form the limiting groove 80, which longitudinal flanges 92 are provided with spacers 94, which spacers 94 are held fixed by spacer bolts 96, which spacer bolts 96 in addition lock the complementary cylindrical parts 88 and 90 to each other. Furthermore, the housing 52 has a drop-shaped cross section (fig. 2), which offers relatively little resistance.
The present invention has found in continuous improvement experiments that the above technique has some problems of insufficient combustion and unstable flame, and for this reason the present invention further proposes an improved gas cooking range for Chinese food, see fig. 3, which shows an improved burner 10a, different from the burner 10 of fig. 1 and 2.
Fig. 1 and 2 primarily stabilize the flame by the outer chamber 50a to increase the combustion effect. However, the improved gas cooker, which has a smaller size and volume and is also improved only around the burner housing 16a, provides a significant development cost saving.
In this modified burner, the shroud 52a is constructed in much the same way as the previous shrouds, except that it includes a part-cylindrical portion 58 a. A portion of the peripheral wall 56a extends between the end flanges 42a of the longitudinal burner housings 16a and abuts only on the side opposite the longitudinal burner housing upper surface 24a, thereby dividing the remaining portion 74a in the outer chamber 50a into a left side cavity 100 and a right side cavity 102. The left and right chambers 100 and 102 communicate with the airflow passage 72a, respectively. The part-cylindrical portion 58a of the peripheral wall 56a has leg formations 104 at opposite ends thereof; the peripheral wall 56a is mounted on the end flange 42a of the longitudinal burner housing by means of leg structures 104. Air enters the chamber portions 100 and 102 through longitudinal openings 106 formed in the peripheral wall 56a, and by impinging baffles 108 therefrom, the baffles 108 direct the air into the openings 106, and thus into the outer chamber 50 a.
According to the invention, through the manner, flame can be stabilized, combustion efficiency is increased, especially by heating air around the stove body, discomfort of taste caused by direct burning of cooking materials by burning flame to ignite internal edible oil or the cooking materials is avoided, the cooking materials in the pot can be ensured to be always in a uniform temperature range, and flameout phenomenon is reduced.
