Description

TECHNICAL FIELD

[0001] The utility model relates to a gas appliance. BACKGROUND

[0002] Some large-diameter pots are placed on the gas appliance for use, that is, the diameter of the pot allows it to be placed on multiple burners at the same time. In the use of the above-mentioned pot, the traditional multi-burner gas appliance can only heat the outer periphery of the pot, resulting in low temperature in the center of the pot and poor cooking effect.

[0003] Patent CNN220061742U discloses a multi-jet burner, which comprises a bottom plate, an upper shell, a plurality of outer ring jet combustion fire covers, a center jet combustion fire cover, and longitudinal oxygen inlet holes. A gas distribution cavity is formed between the upper shell and the bottom plate. A center gas hole is provided in the center of the upper shell and covered with a center jet combustion fire cover. A plurality of Y-shaped gas distribution flow channels are provided in the bottom of the upper shell and extend radially, and the front ends of the channels are in communication with the gas distribution cavity. An outer ring gas outlet hole is provided in the top of each branch flow channel at the end of the Y-shaped gas distribution flow channel, and the branch flow channel is in communication with the outer ring gas outlet hole. The top openings of all the outer ring gas outlet holes are covered with outer ring jet combustion fire covers. Longitudinal oxygen inlet holes are provided between adjacent Y-shaped gas distribution flow channels. The Y-shaped gas distribution flow channel reduces the number of gas distribution flow channels and the complexity of the structure of the gas distribution flow channels, and the overall gas distribution flow is more uniform and the gas flow pressure is more balanced.

[0004] This multi-jet burner is the same as the traditional burner, that is, it has inner ring flame and outer ring flame control, and its design cannot meet the cooking needs of large-diameter pots. UTILITY MODEL CONTENTS

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] Example 1, see Figures 1-11 As shown, a gas appliance includes a housing 1, a burner head 2 mounted on the housing 1, and a control valve 3. In this embodiment, one burner head 2 is controlled by one control valve 3.

[0041] The burner head 2 is provided with a centrifugal combustion zone 21 and a centrifugal combustion zone 22. Specifically, the burner head 2 includes an air inlet seat 4, a flame cap seat 5, and a flame cap 6. The flame cap seat 5 sits on the air inlet seat 4, and the centrifugal combustion zone 21 and the centrifugal combustion zone 22 are provided on the flame cap seat 5. A flame cap 6 sits on the flame cap seat 5 and is located above both the centrifugal combustion zone 21 and the centrifugal combustion zone 22. The air inlet seat 4 supplies air to the centrifugal combustion zone 21 and the centrifugal combustion zone 22 independently. The top of the flame cap seat 5 is provided with a recessed combustion chamber 50, and the center of the combustion chamber 50 is provided with a second air supply hole 52. An arc-shaped wall is provided on one side of the second air supply hole 52. 53. At both ends of the arc-shaped enclosure 53, there are partition walls 54 radially arranged along the burner seat 5. The ends of the partition walls 54 extend to abut against the side wall of the combustion chamber 50. The arc-shaped enclosure 53 and the partition walls 54 divide the combustion chamber 50 into the centrifugal combustion zone 21 and the centrifugal combustion zone 22. The second air supply hole 52 is connected to the centrifugal combustion zone 22. The bottom surface of the combustion chamber 50 is provided with a first air supply hole 51 corresponding to the middle of the centrifugal combustion zone 21. The side wall of the combustion chamber 50 is provided with a number of fire holes 55.

[0042] The outer side of the burner cap 5 has a laterally concave notch 56 corresponding to the centripetal combustion zone 21. The notch 56 communicates with the centripetal combustion zone 21, and an ignition needle 7 is provided at the notch 56. Preferably, the notch 56 is located on the central axis of the arc of the centripetal combustion zone 21. The top of the ignition needle 7 is positioned below the burner cap 6.

[0043] In this invention, there are at least two burner heads 2. The centripetal combustion zones 21 of each burner head 2 are all oriented towards the center of the corresponding burner head 2 arrangement. The control valve 3 controls the burner head 2 to operate with at least one centripetal combustion zone 21. The flames of the centripetal combustion zones 21 of all burner heads 2 are oriented towards the center to form a central combustion zone. Generally, the sum of the angles between the centripetal combustion zones 21 and the centrifugal combustion zones 22 is 360°, the angle of the centripetal combustion zones 21 is 90-180°, and the angle of the corresponding centrifugal combustion zones 22 is 270-180°.

[0044] In this embodiment, there are four burners 2 arranged in a rectangular array, with the centripetal combustion zones 21 of all four burners 2 facing the center of the rectangular array. If the rectangular array is square, the center of the rectangular array is the point where the central axes of the centripetal combustion zones 21 of the four burners 2 coincide. The included angle of the centripetal combustion zones 21 of the burners 2 is 120°, and the included angle of the corresponding centrifugal combustion zones 22 is 240°.

[0045] The bottom of the flame cap base 5 is provided with a limiting bracket 57. The flame cap base 5 sits on the air intake base 4 through the limiting bracket 57. An air intake channel 8 is left between the flame cap base 5 and the air intake base 4. The air intake channel 8 is connected to the mixing chamber 40 of the air intake base 4. The first air supply hole 51 extends downward to the first air guide cylinder 58. The second air supply hole 52 extends downward to the second air guide cylinder 59. The air intake base 4 is provided with a first ejector tube 41 and a second ejector tube 42. The outlet of the first ejector tube 41 is located directly below the first air guide cylinder 58. The outlet of the first ejector tube 41 is connected to the first air guide cylinder 58 through the mixing chamber 40. The outlet of the second ejector tube 42 is located directly below the second air guide cylinder 59. The outlet of the second ejector tube 42 is connected to the second air guide cylinder 59 through the mixing chamber 40.

[0046] The housing 1 includes a front panel 11 and a bottom shell 12. The front panel 11 covers the bottom shell 12. The burner head 2 also includes a connecting plate 9. The connecting plate 9 is connected and fixed to the outer periphery of the air inlet seat 4 by screws. The front panel 11 is provided with mounting holes 10 corresponding to the air inlet seat 4. The outer diameter of the connecting plate 9 is larger than the diameter of the mounting holes 10. The air inlet seat 4 is placed inside the bottom shell 12 through the mounting holes 10. The connecting plate 9 sits on the front panel 11. The bottom surface of the connecting plate 9 and the burner cover seat 5 has an inlet for the air inlet channel 8.

[0047] In this embodiment, the control valve 3 has at least three positions.

[0048] See Figure 8 When control valve 3 is in the first position, it is in the closed state, meaning that gas cannot be supplied to burner 2 through control valve 3, and burner 2 is in the closed state.

[0049] See Figure 9When control valve 3 is in the second position, i.e., rotated 90° counterclockwise, it is fully open. At this time, gas enters both the first ejector tube 41 and the second ejector tube 42 of the burner head 2. Both the centrifugal combustion zone 21 and the centrifugal combustion zone 22 of the burner head 2 are in operation, meaning they are in a high-fire state. Specifically, after the ignition needle 7 ignites the gas in the centrifugal combustion zone 21, the flame spreads from the gas in the centrifugal combustion zone 21 to the centrifugal combustion zone 22, thereby igniting the gas in the centrifugal combustion zone 22.

[0050] See Figure 10 When control valve 3 is rotated 45° counterclockwise from the second position to the first position, it closes halfway, meaning that gas enters both the first ejector tube 41 and the second ejector tube 42 of the burner head 2. At this time, both the centrifugal combustion zone 21 and the centrifugal combustion zone 22 of the burner head 2 are in operation, i.e., they are in a low-fire state. Rotating control valve 3 counterclockwise from the second position to the first position again reduces the firepower of the centrifugal combustion zone 21 and the centrifugal combustion zone 22 until they are completely shut off.

[0051] See Figure 11 When control valve 3 is in the third position, it controls the gas supply to the first ejector tube 41 while stopping the gas supply to the second ejector tube 42. At this time, only the centripetal combustion zone 21 of the burner head 2 is in operation, while the centrifugal combustion zone 22 is closed, meaning both the centripetal combustion zone 21 and the centrifugal combustion zone 22 are in a low-fire state. Rotating control valve 3 counterclockwise from the second to the third position keeps the centripetal combustion zone 21 in combustion mode, while the firepower of the centrifugal combustion zone 22 decreases until it is shut off. The centripetal combustion zones 21 of the four burners 2 form the central combustion zone.

[0052] Example 1, see Figure 12 As shown, the difference between this and Embodiment 1 is that there are two burners 2, which are arranged side by side. The centripetal combustion zones 21 of the two burners 2 are symmetrically arranged on the left and right sides, and the included angle of the centripetal combustion zones 21 is 180°. The included angle of the corresponding centrifugal combustion zones 22 is also 180°.
