Description

Gas range {GAS RANGE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gas range, and more particularly, to a gas range configured to heat a food contained in a cooking vessel by a flame method and a conduction method.

Generally, in a restaurant, unlike a domestic gas range, a gas range is used to shorten the cooking time by heating the food in an early time.

In the conventional gas range for a restaurant, although the flame intensity of the burner is often increased in order to cook the food, the supply of gas and air to the burner is not performed smoothly, and the desired flame strength can not be obtained.

Further, when the thermal power of the burner is weakly adjusted, the operator rotates the handle portion of the mixing valve for the gas range in the direction of the fire extinguishing side so as to weakly control the thermal power of the burner.

However, the burner may be extinguished when the gas supplied to the burner is cut off in the process of rotating the handle in the direction of the extinguishing side. In this case, the operator must re-ignite the burner. Therefore, the operator must pay attention to the weak control of the burner's firepower.

On the other hand, there is a directing method in which food is cooked by direct heating heat of the direct heat radiated from a firearm when food is cooked, and a conduction method of cooking food by conduction heat by heating a roast plate and containers, . For example, when a meat is roasted on a charcoal fire by a direct fire method, the far infrared ray emitted from the charcoal boils the inside and the inside of the meat at the same time, the surface of the meat becomes crispy, and the inside of the meat becomes smooth.

On the other hand, when the grilled meat is bred using the grill plate, the surface of the grilled meat is ripe and the moisture evaporates on the opposite side, so that the meat is tired and the peculiar flavor of the meat disappears.

However, if the food is cooked by the flame method, the texture of the food can be increased, but the oil leaking out from the food falls into the fire, which makes cooking difficult.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a method and apparatus for supplying gas and air to a burner smoothly, So as to provide a gas range.

FIG. 1 is a perspective view of a gas range according to an embodiment of the present invention, FIG. 2 (a) is a side view illustrating a state where a first mixing valve and a first burner are combined according to an embodiment of the present invention, FIG. 2C is a side elevational view illustrating a state in which a second mixing valve and a second burner are combined according to an embodiment of the present invention, and FIG. 2C is a plan view of a gas range according to an embodiment of the present invention.

1 and 2, the gas range 2000 includes a body portion 1100, a first burner 1200, a wall portion 1300, a second burner 1400, a first mixing valve 1500, A second mixing valve 1600 may be included. The body portion 1100 forms the outer shape of the gas range 2000 and is supported by various devices.

The wall portion 1300 is connected to the body portion 1100 and protrudes upward from the body portion 1100. When the gas range 2000 is brought into close contact with the wall surface, the wall portion 1300 is brought into contact with the wall surface together with the body portion 1100 to prevent the gas range 2000 from shaking. In addition, the wall portion 1300 safely protects the extension pipe 530 supplying the mixed air and gas from the second burner 1400 from the outside.

The first burner 1200 is coupled to the body part 1100 and heats the lower surface of the cooking container 20 placed on the container pedestal 10 to heat the food contained in the cooking container 20 . The first burner 1200 can selectively control the thermal power of the first burner 1200 by selectively operating the first mixing valve 1500. That is, the first burner 1200 heats the cooking vessel 20 and heats the food contained in the cooking vessel 20 with the conductive heat.

The second burner 1400 is configured to heat the food stored in the cooking container 20 with the flame while the second burner 1400 is supported by the wall portion 1300. The second burner 1400 is configured to heat the food contained in the cooking container 20, The thermal power of the second burner 1400 can be selectively adjusted. Unlike the first burner 1200, the second burner 1400 does not cook the food by heating the cooking vessel 20, but directly transfers the thermal power to the food contained in the cooking vessel 20 to cook the food.

Foods heated by the second burner 1400 in a flame-proof manner are removed from the noodles, and charcoal is added to the food, thereby enhancing the texture of the food when consumed.

The second burner 1400 has a height 15 to 20 cm upward from the container pedestal 10 so that the direct thermal power is transferred to the food contained in the cooking container 20 in a state where the cooking container 20 is seated in the container pedestal 10 (h). This is for the purpose that the thermal power radiated from the second burner 1400 can be heated by direct heating on food and beverages provided in the cooking container 20 and is safe from thermal power radiated to the operator.

In other words, when the second burner 1400 is positioned at a height exceeding 20 cm from the container pedestal 10, the range of the thermal power radiated from the second burner 1400 is widened, And the distance between the food stored in the cooking container 20 and the second burner 1400 becomes far away, so that the second burner 1400 must eject a strong thermal power. Therefore, there is a problem that the amount of gas used is increased.

When the operator places the cooking container 20 and the second burner 1400 in the process of mixing the food stored in the cooking container 20 with the second burner 1400 positioned at a height of less than 15 cm from the container pedestal 10, So that the cooking operation is inconvenient.

Accordingly, the second burner 1400 is provided at a height of 15 to 20 cm upward from the container support 10, so that the food contained in the cooking container 20 is heated by the flame. It is needless to say that the height of the second burner 1400 is not limited to a height of 15 to 20 cm upward from the container holder 10, and may be variously arranged at the request of the operator.

The second burner 1400 is located at a position spaced a distance from the first burner 1200 and is configured to eject the thermal power radiated from the second burner 1400 to the center of the first burner 1200. That is, the second burner 1400 is positioned at one side of the first burner 1200 and forms an inclined angle a of 40 to 60 degrees with respect to the horizontal line toward the center of the first burner 1200 . Therefore, the food contained in the cooking container 20 in a state in which the cooking container 20 is placed on the container holder 10 can be heated by the direct burning by the second burner 1400.

The second burner 1400 is located above the first burner 1200 so that the thermal power is radiated toward the center of the first burner 1200 so that the operator can grasp the cooking knob 21 In the case where the food contained in the cooking container 20 is moved up and down when the food contained in the cooking container 20 is moved up and down and shuffled while waving the cooking container 20 using the snap of the wrist while being held, So that it can be prevented from touching the burner 1400. That is, the second burner 1400 is located at one side from the first burner 1200 to prevent the food from contacting the second burner 1400 in the process of mixing the food stored in the cooking container 20, can do.

FIG. 3 is a perspective view of a first mixing valve according to an embodiment of the present invention, FIG. 4 is an exploded perspective view of a first mixing valve according to an embodiment of the present invention, FIG. FIG. 6A is an exemplary view showing a rotating part and a mixing part viewed from the front according to an embodiment of the present invention, and FIG. 6B is a cross-sectional view illustrating a mixing part with a rotating part viewed from the rear according to an embodiment of the present invention. Fig.

3 to 6, the first mixing valve 1500 may include a mixing unit 100, a gas nozzle 200, a housing unit 300, and a gas control unit 400.

The gas guide hole 110 formed in the mixing part 100 selectively moves the gas supplied from the gas pipe 1 to the first burner 1200 and the air guide hole 120 formed in the mixing part 100 ) Selectively moves the air supplied from the air tube 2 to the first burner 1200.

At this time, the mixing unit 100 adjusts the amount of the gas supplied from the gas pipe 1 and the air supplied from the air pipe 2 according to the rotation to mix the gas and the air, and then supplies the mixture to the first burner 1200 do.

Here, a blower motor (not shown) is coupled to the air tube 2 so that the air provided in the air tube 2 is forcibly blown, so that the first burner 1200 can maintain a high heating power. That is, the first burner 1200 can generate a high heating power even by using a small amount of gas, which helps reduce the gas cost.

The air guide hole 120 is formed at a central portion of the mixing portion 100 and is formed so as to pass through the mixing portion 100 in a direction perpendicular to the longitudinal direction of the mixing portion 100. The air guide hole 120 is formed to selectively communicate with the first hole 311 and the second hole 312 formed in the first housing 310 according to the rotation of the mixing portion 100, And guides the supplied air to the discharge pipe 510.

One side of the gas guide hole 110 formed in the mixing portion 100 is communicated with the air guide hole 120 and the other side is opened on the other side of the mixing portion 100. That is, the gas guide hole 110 is formed to penetrate from the air guide hole 120 in the longitudinal direction of the mixing part 100, and the gas introduced from the gas nozzle 200 according to the rotation of the mixing part 100, (120).

The mixing unit 100 mixes the air supplied to the air guide hole 120 and the gas supplied to the gas guide hole 110 and then guides the mixture to the discharge pipe 510 through the first hole 311 .

Here, the housing part 300 may include a first housing 310 and a second housing 320. The first housing 310 may be provided outside the mixing part 100, Wrap. The second housing 320 is coupled to the other side of the first housing 310 and surrounds the gas nozzle 200.

The housing part 300 prevents air and gas flowing into the mixing part 100 from leaking to the outside and protects the mixing part 100 and the gas nozzle 200 from the outside.

A gas inlet hole 210 is formed in the lower part of the gas nozzle 200 so that the gas supplied from the gas pipe 1 can be selectively introduced into the gas guide hole 110.

The gas nozzle 200 is moved up and down according to the rotation of the mixing part 100 and the amount of gas flowing into the gas inlet hole 210 can be controlled by selectively controlling opening and closing of the gas inlet hole 210 . That is, the gas control unit 400 is eccentrically coupled to the other side of the mixing unit 100 to control the pressurization of the gas nozzle 200 according to the rotation of the mixing unit 100 to control the opening / closing amount of the gas inlet hole 210 .

The first mixing valve 1500 may further include a discharge pipe 510, a rotation unit 600, a stopper cap 700, a rear cap 800, and a connection pipe 520.

The discharge pipe 510 is coupled to the first housing 310 and is connected to the first hole 311 to guide the mixed air and gas supplied from the mixing unit 100 to the first burner 1200 do.

The rotation unit 600 is coupled to one side of the mixing unit 100 so that when the operator rotates the knob unit 620 provided on the rotation unit 600, the mixing unit 100 rotates together with the rotation of the knob unit 620 . Accordingly, the operator can control the thermal power of the first burner 1200 by controlling the supply amount of the gas and air supplied to the first burner 1200 through the rotation of the handle 620.

The stopper cap 700 is coupled to one side of the first housing 310 to control the rotation angle of the rotation unit 600. That is, the stopper cap 700 restrains the rotation of the projecting pin 640 provided on the rotation part 600 to control the rotation angle of the rotation part 600.

The stopper cap 700 is coupled to one side of the first housing 310 and the rear cap 800 is coupled to the other side of the first housing 310, To the outside.

One end of the connection pipe 520 is coupled to the discharge pipe 510 and the other end of the connection pipe 520 is connected to the first burner 1200 to supply the mixed gas and air discharged to the discharge pipe 510 1 burner 1200 as shown in FIG.

5 and 6, the rotation unit 600 may include a rotating body 610, a handle 620, an engaging pin 630, a projecting pin 640, and a second elastic member 650.

The rotary body 610 forms an outer shape of the rotary part 600 and the rotary body 610 has an engaging pin 630 coupled to one side of the rotary body 610 and a knocking part 630 coupled to the mixing part 100 at the other side thereof . Therefore, when the operator rotates the grip portion 620, the mixing portion 100 can be rotated together with the rotation of the grip portion 620. [

The coupling pin 630 is inserted into the moving groove 301 formed in the longitudinal direction of the mixing unit 100 and the coupling pin 630 can be moved along the moving groove 301.

That is, when the operator intends to ignite the first burner 1200 in the extinguished state, the worker presses the handle 620 with a certain force or more to release the protrusion (not shown) that is seated in the fixing groove 701 of the stopper cap 700 The ignition and the thermal power of the first burner 1200 are controlled by moving the pin 640 to the outside of the fixing groove 701 and rotating the pin 640.

Since the rotation part 600 is not rotated in the state where the projecting pin 640 is seated in the fixing groove 701, the operator presses the holding part 620 to push the projecting pin 640 into the fixing groove 701, The knob portion is rotated. The engaging pin 630 coupled to the rotating body 610 may be moved along the moving groove 301 during the pressing operation of the holding portion 620 and may be moved along the engaging pin 630 during rotation of the holding portion 620, The mixing chamber 100 is rotated by pressing the moving groove 301 in the rotating direction.

The protruding pin 640 is connected to the rotating body 610 while maintaining a certain distance from the engaging pin 630. When the operator places the handle 620 in a rotated state, The protrusion pin 640 is supported and fixed to the support groove 702 of the stopper cap 700 by applying an elastic force to the rotary body 610. That is, one end of the second elastic member 650 is supported by the rotating body 610, and the other end is supported by the mixing part 100 to elastically support the rotating body 610.

Thus, the operator can control the thermal power of the first burner 1200 through the rotation angle of the handle portion 620. [ At this time, the first stopper 710 and the second stopper 720 are provided on the stopper cap 700 to constrain the rotation angle of the protrusion pin 640. That is, the first stopper 710 and the second stopper 720 restrict the rotation range of the projecting pin 640 by controlling the rotation angle of the projecting pin 640.

The first stopper 710 and the second stopper 720 can limit the rotation range of the projecting pin 640 to a range of 0 ° to less than 180 °. However, since the first burner 1200 is not extinguished The projecting pin 640 may limit the rotation range to a range of 0 ° to 160 ° in order to stably lower the thermal power.

Specifically, when the handle 620 located at 0 ° to the digestion side is rotated by 90 °, the eccentrically-coupled gas regulator 400 moves the gas nozzle 200 downward, 210 are placed in the open state and the amount of gas supplied to the first burner 1200 is maximally supplied.

In this state, when the worker lowers the thermal power of the first burner 1200, the operator does not rotate the handle 620 in the direction of the fire extinguishing side but moves in the direction of 90 degrees to 160 degrees or less The operator can selectively lower the thermal power of the first burner 1200 without causing the first burner 1200 to be extinguished. The operator rotates the handle 620 in the direction of the fire extinguishing side of less than 90 degrees, It is needless to say that the thermal power of the burner 1200 can be selectively lowered.

The first mixing valve 1500 may further include a nozzle cap 910, a first elastic member 920, and a gas supply control unit 930.

The nozzle cap 910 is provided inside the second housing 320 to guide the movement of the gas nozzle 200 when the gas nozzle 200 is moved up and down. That is, when the gas control unit 400 eccentrically coupled to the mixing unit 100 is rotated, the gas nozzle 200 is moved up and down by the gas control unit 400, and the nozzle cap 910 is moved up and down The direction of movement of the gas nozzle 200 is guided.

Here, the case where the gas is introduced into the gas inlet hole 210 from the gas pipe 1 is referred to as an open state, the state in which the gas inlet hole 210 is fully opened from the nozzle cap 910 is referred to as a completely opened state, The open state is referred to as a partially open state. The gas inlet hole 210 is blocked by the nozzle cap 910 to block the movement of the gas, which is referred to as a closed state.

In other words, when the gas regulating unit 400 eccentrically connected to the other side of the mixing unit 100 is moved downward according to the rotation of the mixing unit 100, the gas regulating unit 400 moves the gas nozzle 200 downward And the gas inlet hole 210 is exposed to the outside of the nozzle cap 910 to maintain the open state in which gas flows into the gas inlet hole 210.

In contrast, when the gas regulating unit 400 eccentrically connected to the other side of the mixing unit 100 is moved upward according to the rotation of the mixing unit 100, the gas regulating unit 400 includes the first elastic member 920, The gas nozzle 200 is moved upward and the gas inlet hole 210 is moved to the inside of the nozzle cap 910 so that the gas inlet hole 210 is closed. In other words, the opening and closing of the gas inflow hole 210 is controlled in accordance with the upward and downward movement of the gas control unit 400.

A sealing member 220 is provided at the lower end of the gas nozzle 200 to block gas from flowing between the gas nozzle 200 and the nozzle cap 910 when the gas inlet hole 210 is closed.

The gas nozzle 200 has a structure in which the gas nozzle 200 is moved up and down in accordance with the pressure of the gas regulator 400 and the gas nozzle 200 is not rotated.

The gas nozzle 200 is a component independent of the mixing part 100. The operator can easily remove the gas nozzle 200 to replace or repair the gas nozzle 200 when the gas nozzle 200 is defective or maintenance- .

A gas supply control unit 930 is provided below the second housing 320. The gas supply control unit 930 controls the flow of the gas flowing from the gas pipe 1 to the interior of the second housing 320 The pressure is adjusted. That is, the gas supply control unit 930 controls the pressure of the gas flowing into the second housing 320 from the gas pipe 1, and guides the gas to the gas inlet hole 210.

7 is a perspective view illustrating a state in which the knob portion of the first mixing valve according to the embodiment of the present invention is rotated by 0 ° Fig. 5 is a view showing the operating state of the rotating part and the gas nozzle in the state of Fig.

As shown in FIG. 7, the first burner 1200 (see FIG. 5) is in a state in which the handle 620 is positioned at 0 °. 5) is positioned in the fixing groove 701 (see FIG. 5), and the gas inlet hole 210 is closed by the nozzle cap 910, that is, the gas inlet hole 210 Is maintained in the closed state.

In this case, although the air guide hole 120 is kept closed in the first housing 310, the mixing part 100 is not completely in close contact with the first housing 310. That is, the mixing unit 100 adjusts the inflow amount of the gas and the air through the rotation of the first mixing unit 100 while maintaining the minimum separation distance for rotating the first mixing unit 100 from the first housing 310, . A fine gap 313 is formed between the mixing unit 100 and the first housing 310 to rotate the mixing unit 100 from the first housing 310.

That is, in a state in which the valve in which the handle 620 is positioned at 0 ° is blocked, the gas inlet hole 210 is kept in a completely closed state, and the gas is not supplied to the mixing portion 100 On the other hand, the air that has flowed from the second hole 312 into the first housing 310 and the fine gap 313 of the mixing unit 100 is continuously supplied to the discharge pipe 510 through the first hole 311 do. The air supplied to the discharge pipe 510 is supplied to the connection pipe 520 and discharged to the outside through the first burner 1200 even when the handle 620 is positioned at 0 °. At this time, the amount of air discharged to the outside through the first burner 1200 is very small.

The air introduced into the first housing 310 and the fine gap 313 of the mixing unit 100 is discharged through the discharge pipe 510 and the connection pipe 520 while the handle 620 is positioned at 0 °, So that the gas remaining in the discharge pipe 510 and the connecting pipe 520 at the time of ignition of the first burner 1200 is discharged backward by the gas remaining in the connecting pipe 520. [ Back fire can be prevented in advance. Therefore, it is possible to prevent the occurrence of backfire from the first burner 1200 to prevent various devices such as the connection pipe 520 from being damaged.

Next, FIG. 8 is an operational state diagram of the rotating part and the gas nozzle in the 45 ° state of the handle of the first mixing valve according to the embodiment of the present invention.

8, the air guide hole 120 is partially communicated with the first hole 311 and the second hole 312 when the handle 620 is rotated from the 0 ° reference point by 45 ° . The eccentrically coupled gas regulator 400 presses the gas nozzle 200 downward and exposes a portion of the gas inlet hole 210 to the outside of the nozzle cap 910 so that gas is introduced into the gas inlet hole 210 .

The gas inlet hole 210 formed in the gas nozzle 200 has a gradually narrower width than the gas inlet hole 210 so that it flows into the gas inlet hole 210 according to the position of the gas nozzle 200 The amount of gas inflow can be adjusted.

When the handle 620 is rotated by 45 degrees, the air guide hole 120 and the gas inlet hole 210 are partially opened and the air guide hole 120 and the gas inlet hole 210 are communicated with each other Air and gas can be introduced into the first burner 1200 (see FIG. 5).

Next, FIG. 9 is an operational state diagram of the rotating part and the gas nozzle in the state where the handle part of the first mixing valve is in a 90 ° state according to an embodiment of the present invention.

9, when the handle 620 is rotated by 90 °, the air guide hole 120 is communicated with the first hole 311 and the second hole 312, The gas inlet hole 210 is completely exposed to the outside of the nozzle cap 910 so that the gas nozzle 200 is maintained in a completely open state.

In other words, the eccentrically-coupled gas regulator 400 moves the gas nozzle 200 downward to position the gas inlet hole 210 in a fully opened state to increase the amount of gas supplied to the first burner 1200 (see FIG. 5) As shown in FIG.

In this state, since the amount of air and gas supplied to the first burner 1200 (see FIG. 5) is maximized, the first burner 1200 (see FIG. 5) can maintain the maximum thermal power.

10 is an operational state diagram of a rotating part and a gas nozzle in a state where the handle of the first mixing valve is in a state of 160 ° according to an embodiment of the present invention.

10, when the handle 620 is rotated by 160 °, the air guide hole 120 is partially communicated with the first hole 311 and the second hole 312, 620 are 45 degrees, the amount of air supplied to the first burner 1200 (see FIG. 5) is small. In the case of the gas inlet hole 210, the communicating portion of the gas inlet hole 210 is smaller than the case of forming the handle portion 620 at 45 °, It is also small.

In this way, when the handle 620 is rotated 90 degrees and the first burner 1200 (see FIG. 5) keeps the maximum thermal power and the thermal power of the first burner 1200 (see FIG. 5) is lowered, (See FIG. 5) by adjusting the communication portion between the air guide hole 120 and the gas inlet hole 210 by rotating the first air blower 620 in the direction of 90 ° or more without rotating in the 0 ° direction Can be lowered.

The first stopper 710 and the second stopper 720 are provided on the stopper cap 700 so that the rotational angle of the protruding pin 640 is restricted so that the handle 620 is rotated from 0 ° to 160 ° The range of rotation is limited.

That is, when the operator rotates the handle 620 by 90 degrees or more, the operator can rotate the handle 620 at a maximum of 160 degrees or less. When the handle 620 is rotated by 160 degrees, A portion of the gas guide hole 110 is communicated with the hole 311 and the second hole 312 and the gas guide hole 110 is partially opened to the outside of the nozzle cap 910, The firepower of the first burner 1200 (see FIG. 5) can be stably lowered without being extinguished.

Therefore, when the worker lowers the thermal power of the first burner 1200 (see Fig. 3), the operator does not rotate the handle 620 in the digesting direction (0 占 direction) It is also possible to lower the thermal power of the first burner 1200 (see FIG. 5) without the first burner 1200 (see FIG. 5) being extinguished by rotating the handle 620 at an angle of about 160 ° or less.

Thus, the operator can control the thermal power of the first burner 1200 (see FIG. 5) by controlling the amount of opening and closing of the air guide hole 120 and the gas inlet hole 210 through the rotation of the handle 620 .

Referring again to FIG. 2B, the second mixing valve 1600 may include an air control unit 1610 and a gas control unit 1630. The air control unit 1610 selectively moves the air supplied from the air tube 2 to the second burner 1400.

An air guide hole 120 'is formed in the air control unit 1610 to supply the air supplied from the air tube 2 to the second burner 1400 through the extension pipe 530. Unlike the mixing portion 100, the air control portion 1610 does not form the gas guide hole 110. [ Accordingly, the air control unit 1610 selectively controls only the air supplied to the second burner 1400.

The air control unit 1610 adjusts the amount of air supplied to the air tube 2 by the rotation of the mixing unit 100, and then supplies the air to the second burner 1400. That is, the air control unit 1610 is configured to guide only the movement of the air, and the configuration of the gas nozzle 200 and the gas control unit 400 provided in the first mixing valve 1500 is unnecessary.

A blowing motor (not shown) is coupled to the air tube 2, and the air supplied to the second burner 1400 is forcedly blown. Therefore, the second burner 1400 can generate a high heating power even by using a small amount of gas, which helps reduce the gas cost.

In this case, the air control unit 1610 continuously supplies the air to the extension pipe 530 even when the knob 620 'of the second mixing valve 1600 is positioned at 0 ° as in the mixing unit 100, And is discharged to the outside through the burner 1400. The amount of air discharged to the outside through the second burner 1400 is very small. It goes without saying that the air control unit 1610 may be operated in a state where the handle 620 'is not separately provided.

Meanwhile, the gas control unit 1630 may include a gas supply pipe 1631, a gas valve 1632, and a foot plate 1633. The gas supply pipe 1631 supplies the gas supplied from the gas pipe 1 to the second burner 1400.

This gas supply pipe 1631 is configured to communicate with the extension pipe 530 so that the gas supplied from the gas pipe 1 can be supplied to the extension pipe 530 through the gas supply pipe 1631 and then supplied to the second burner 1400 have. That is, at the point where the gas supply pipe 1631 and the extension pipe 530 meet, the gas and the air are mixed and then supplied to the second burner 1400.

The gas valve 1632 is provided in the gas supply pipe 1631 and controls the gas supplied to the second burner 1400 through selective opening / closing control. The gas valve 1632 controls the thermal power of the second burner 1400 through adjustment of the amount of gas supplied to the second burner 1400.

The control of this gas valve 1632 is made to be interlocked with the operation of the air control part 1610. For example, when the amount of gas supplied to the second burner 1400 is increased under the control of the gas valve 1632, the air control unit 1610 is also adjusted to increase the amount of air supplied to the second burner 1400 The amount of gas supplied to the second burner 1400 is reduced according to the control of the gas valve 1632 and the air control unit 1610 is also adjusted to reduce the amount of air supplied to the second burner 1400.

However, even if gas is not supplied to the second burner 1400 while the gas valve 1632 is maintained in the closed state, the air control unit 1610 controls the second burner 1400 to supply a small amount of air To be continuously discharged.

 Each of the gas valve 1632 and the air control unit 1610 is provided with an operation sensor (not shown) so that the air control unit 1610 can be interlocked with the operation of the gas valve 1632.

On the other hand, the footrest part 1633 is installed on the lower part of the body part 1100 and the gas valve 1632 is turned on / off according to the pressing of the footrest part 1633 by the operator, 1400). ≪ / RTI >

Alternatively, the opening / closing amount of the gas valve 1632 may be adjusted depending on the pressing strength of the foot part 1633 pressed by the operator. But may also be made to selectively adjust.

That is, when the worker increases the pressing strength of the foot part 1633, the opening of the gas valve 1632 is widened to increase the supply amount of gas supplied to the second burner 1400, and the pressing strength of the foot part 1633 is lowered The opening of the gas valve 1632 is reduced to reduce the supply amount of the gas supplied to the second burner 1400.

It is needless to say that the amount of opening and closing of the gas valve 1632 and the amount of rotation of the air control part 1610 can be selectively controlled according to the operating state of the footrest part 1633.

Thus, the operator can easily adjust the thermal power of the second burner 1400 by adjusting the pressing strength of the footstep 1633 provided at the lower portion of the body portion 1100. Thus, the worker who cooks the food can easily adjust the firepower of the second burner 1400 without using his / her hands.

The body portion 1100 may further include a footrest preventing portion (not shown) for preventing the footrest portion 1633 from being pressed. The pedal depression preventing portion (not shown) can control the operation of the pedal depressor 1633 through an ON / OFF operation. That is, even when a strong force is applied to the footrest 1633 in a state where the footrest preventing portion (not shown) is turned ON, the footrest 1633 is not pressed. Therefore, in the case where the second burner 1400 is not used, an accident that may be caused by pressing the foot plate 1633 by mistake can be prevented in advance.

On the other hand, in order to use the footrest 1633, the worker controls the thermal power of the second burner 1400 by pressing the footrest 1633 in a state where the footrest preventing portion (not shown) is turned off .

FIG. 11 is a perspective view of a gas range according to another embodiment of the present invention. In the gas range 3000, two or more first burners 1200 and second burners 1400 may be provided. That is, the number of the first burner 1200 and the number of the second burner 1400 may be variously set according to the working environment. In order to correspond to the number of the first burner 1200 and the second burner 1400, It is needless to say that the number of the valve 1500 and the number of the second mixing valve 1600 may be the same.
