Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a burner and a stove. Background Technology

[0002] With the continuous integration and development of Eastern and Western dietary styles, people have increasingly wider requirements for the adjustment range of gas stove power (firepower). Western cuisine requires even firepower, while Chinese cuisine requires concentrated low heat and the ability to stir-fry over high heat.

[0003] However, most existing burners use a dual-injector tube structure, where gas and air are mixed separately through two injectors and introduced into the outer and inner ring gas passages (or central gas passages) respectively, igniting them to produce outer and inner ring flames (or central flames). Additionally, there are also triple-injector tube and single-injector tube structures. Stoves typically consist of two or three burners with the same injector tube structure, making it difficult to achieve a single stove with the heat output suitable for both Western cooking and the stir-frying requirements of Chinese cuisine.

[0035] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0036] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0037] Figure 1 and Figure 2 A stove according to an embodiment of the present invention is shown. For example... Figure 1 and Figure 2 As shown, the stove may include a stove housing 6, a first burner 1, and a second burner 2. The stove housing 6 encloses a stove cavity that accommodates at least a portion of the first burner 1 and the second burner 2. The first burner 1 and the second burner 2 are respectively fixed to the bottom of the stove housing 6, and the top portions of the first burner 1 and the second burner 2 extend upwards out of the stove cavity.

[0038] According to an exemplary embodiment of the first burner 1, such as Figure 3 and Figure 4 As shown, the first burner 1 includes a first ejector section 11, a first mixing section 12, and a first base 13. The first mixing section 12 is located at one end of the first ejector section 11, and the top of the first mixing section 12 has a first opening 121, the shape of which is a first portion of a first shape. The other end of the first ejector section 11 is connected to the first base 13 via a first rotating mechanism 3, so that the first ejector section 11 can drive the first mixing section 12 to... Figure 1 The second burner 2 switches between a first position and a second position within the horizontal plane shown. The second burner 2 includes a second mixing section 21, the top of which has a second opening 211, the shape of which is a second portion of a first shape. When the first mixing section 12 is positioned in the first position, the first burner 1 is used as a standalone burner since no other burners are arranged in the first position. When the first mixing section 12 is positioned in the second position, as... Figure 10As shown, a second burner 2 is provided at the corresponding position of the second position, and the first mixing section 12 and the second mixing section 21 are adapted to each other so that the flames of the first opening 121 and the second opening 211 form a complete first shape. Of course, when the second burner 2 can also be set in the first position, the first mixing section 12 and the second burner 2 form a combined burner when in the first position, and are used alone in the second position. It is understood that the first shape can be any shape that includes the first part and the second part, such as a circle, a quadrilateral or a triangle, etc., including but not limited to the shapes listed above, and the first part and the second part are two parts divided by the first shape. For example, the first opening (121) of the first mixing section 12 and the second opening (211) of the second mixing section 21 are both comma-shaped, and the first opening (121) and the second opening (211) are connected end to end to form a circle.

[0039] In addition, the first burner 1 also includes a first burner cap 15 with a first flame hole 151 on the top and a first ignition needle 16 connected to the outer side (the side where the arc is located) of the first mixing section 12. The shape of the first burner cap 15 corresponds to the shape of the first mixing section 12 and covers the first opening 121. A first flame transmission hole 152 is provided on the side wall of the first burner cap 15, and the needle tip of the first ignition needle 16 corresponds to the first flame transmission hole 152.

[0040] According to an exemplary embodiment of the first base 13, such as Figure 5 As shown, the first base 13 forms two first channels 131, and the first burner 1 may further include first nozzles 14 respectively corresponding to the air outlets of the two first channels 131. When the first mixing section 12 is in the first position, the air inlet of the first ejector section 11 faces one of the first nozzles 14. When the first mixing section 12 is in the second position, the air inlet of the first ejector section 11 faces the other first nozzle 14. The two first nozzles 14 correspond to the two positions of the first mixing section 12, and the negative pressure effect generated when the gas in the first nozzle 14 enters the first ejector section 11 simultaneously brings the air between the air inlet of the first ejector section 11 and the first nozzle 14 into the first ejector section 11. In addition, the bottom of the first base 13 is provided with a plurality of first fixing legs 132 extending axially at equal intervals, for connecting the first base 13 to the stove housing 6. It can be understood that in this embodiment, a first channel 131 is provided on the first base 13 for the first position and the second position of the first mixing section 12, respectively. In some other specific embodiments, the first base 13 may also be provided with a first channel 131 having an air inlet channel and two air outlet channels. The air inlet channel is connected to the two air outlet channels respectively, and a control valve is provided at the connection point to control the air inlet channel to selectively connect to one of the air outlet channels.

[0041] According to an exemplary embodiment of the first channel 131, such as Figure 6 As shown, the first channel 131 includes at least a first segment 1311, a second segment 1312, and a third segment 1313 connected in sequence. The first segment 1311 extends inward from the outer periphery of the first base 13 to near the center of the first base 13. The second segment 1312 extends axially along the first base 13. The third segment 1313 extends outward from near the center of the first base 13 to the outer periphery of the first base 13. The first segment 1311 and the third segment 1313 extend radially along the first base 13 and are arranged in parallel. The first segment 1311 is located below the third segment 1313. The first nozzle 14 is located at the air outlet of the third segment 1313. The air inlet of the first segment 1311 is provided with a connector for connecting an air inlet hose. It is understood that the first channel 131 includes, but is not limited to, the structure described above. For example, the first channel 131 may also include any one, two, or three or more connected segments, and the air inlet of the first channel 131 can be set at a position that is convenient for connecting the air inlet hose. The air outlet of the first channel 131 can be adapted to the position of the air inlet of the first ejector 11 when the first mixing section 12 is set in the first position or the second position.

[0042] According to an exemplary embodiment of the first rotating mechanism 3, such as Figure 4 As shown, the first rotating mechanism 3 may include a drive unit 31, a gear (not shown), and a first housing 32. The drive unit 31 may be an AC motor, a DC motor, a stepper motor, or other driving components adapted to rotate the first ejector unit 11 and the first mixing unit 12 within a confined space. The drive unit 31 is connected to the first base 13 such that the output shaft of the drive unit 31 extends axially along the first base 13, thereby connecting the gear to the output shaft of the drive unit 31 and coaxially disposed with the output shaft. One end of the first housing 32 is open and its open end faces the first base 13. At least a portion of the inner sidewall of the first housing 32 (e.g., Figure 4 The first housing 32 shown has a rack 321 on its side wall opposite to the first ejector 11, which meshes with a gear. The first ejector 11 is connected to the first housing 32. It is understood that the number of gears may include, but is not limited to, only one. When the distance from the output shaft to the rack 321 is large, providing only one gear may prevent the first housing 32 from being coaxially connected with the first base 13. In such cases, two or more gears may be provided for switching transmission.

[0043] In some specific embodiments, the inner wall of the first housing 32 corresponding to the opening may extend towards the bottom of the first base 13 to the position between the air inlet of the first ejector 11 and the first nozzle 14. To prevent the first housing 32 from forming an obstruction between the first nozzle 14 and the first ejector 11, in such a way... Figure 4 and Figure 5The first housing 32 shown has an air inlet hole 322 at the air inlet of the first ejector 11. The area of ​​the air inlet hole 322 is larger than the area of ​​the air inlet of the first ejector 11, so that more air can be drawn in when the gas enters the first ejector 11 from the first nozzle 14. Of course, in some other specific embodiments, the inner sidewall of the first housing 32 does not extend to the position between the air inlet of the first ejector 11 and the first nozzle 14, so the air inlet hole 322 is not required.

[0044] Furthermore, such as Figure 6 As shown, the first nozzle 14 extends out of the outer periphery of the first base 13. In order to avoid interference between the first housing 32 and the first nozzle 14 when the first ejector 11 and the first mixing part 12 rotate, a gap 4 can be provided between the inner side wall of the first housing 32 and the first base 13, so that the first housing 32 can avoid the first nozzle 14 when the first housing 32 rotates.

[0045] Furthermore, in order to facilitate cleaning the corresponding lower positions of the first ejector section 11 and the first gas mixing section 12, or to disassemble the panel assembly 7, the first ejector section 11 and the first gas mixing section 12 need to be rotatably connected to the first housing 32, so that the first ejector section 11 and the first gas mixing section 12 can be lifted upward relative to the plane of the panel assembly 7, for example... Figure 4 The image shows the part lifting vertically upwards. Therefore, a first connecting ear 323 can be provided extending outwards from the first housing 32, and the first connecting ear 323 has a first pin hole 3231 extending along the tangent direction of the first base 13. Correspondingly, the first ejector part 11 is provided with a connector 111, and the connector 111 has a second pin hole 1111. After the first pin 5 passes through the first pin hole 3231 and the second pin hole 1111, the first ejector part 11 can be rotatably connected to the first housing 32.

[0046] According to an exemplary embodiment of connector 111, such as Figure 4 As shown, the connector 111 may include a first connecting plate 1112 and a second connecting plate 1113. The first connecting plate 1112 is horizontally and symmetrically placed in a "U" shape. Second pin holes 1111 are respectively provided at both ends of the first connecting plate 1112, and these two ends are respectively located on both sides of the first connecting lug 323. The second connecting plate 1113 is a straight plate, with its approximate middle position for the end of the first ejector 11 away from the first mixing section 12 to pass through. The approximate circumference of the second connecting plate 1113 is bolted to the middle of the first connecting plate 1112.

[0047] According to an exemplary embodiment of the second mixing section 21, such as Figure 7As shown, the second mixing section 21 includes a first segment 212 and a second segment 213 arranged from top to bottom along its axial direction. A second opening 211 is provided at the top of the first segment 212, and at least a portion of the top of the second segment 213 communicates with the first segment 212. For example, if the shape of the cross-section of the first segment 212 perpendicular to the axial direction of the second mixing section 21 is configured as a first shape, and the top surface of the second segment 213 is configured as the first shape, such that the entire bottom surface of the first segment 212 communicates with a portion of the top surface of the second segment 213, then the portion of the second segment 213 not communicating with the first segment 212 forms a clearance area 2132 for the first mixing section 12. Therefore, when the first mixing section 12 is adapted to the second mixing section 21, the first mixing section 12 can still be placed in the clearance area 2132, and the second mixing section 21 can support the first mixing section 12.

[0048] According to an exemplary embodiment of the second paragraph 213, such as Figure 8 As shown, a second channel 2131 extending axially around a portion of the second section 213 is also provided inside the second section 213. The bottom of the second channel 2131 rises in a spiral shape, and the top of the second channel 2131 is connected to the first section 212, so that the gas mixture can rise smoothly in the second section 213 and avoid the turbulent airflow caused by the gas mixture hitting the inner wall of the second section 213.

[0049] In the above embodiment, the second burner 2 further includes a second ejector portion 22 connected to the side of the second section 213 away from the first section 212, and the second ejector portion 22 communicates with the bottom end of the second channel 2131. Specifically, the second ejector portion 22 surrounds and forms a second ejector cavity 221, and the second ejector cavity 221 may include components along the gas flow direction ( Figure 8The gas flow is distributed from right to left as follows: a contraction section 2211, a throat section 2212, a primary diffuser section 2213, and a secondary diffuser section 2214. A nozzle mounting plate 222 is installed at the end of the contraction section 2211 furthest from the throat section 2212 to mount a second nozzle. When gas enters the contraction section 2211 from the indoor gas supply line, a portion of air is drawn in by negative pressure to form a gas mixture. The secondary diffuser section 2214 is a larger cavity structure than the primary diffuser section and is connected to the bottom end of the second channel 2131 of the second section 213. Through the spirally rising second channel 2131, the gas mixture is guided to gradually rise into the first section 212. When the initial gas enters the contraction section 2211, as the cross-sectional area of ​​the contraction section 2211 gradually decreases, the gas forms a jet, creating a suction flow. Due to the high speed of the gas flow, a negative pressure zone appears, thereby drawing in a portion of air from the nozzle and entering the contraction section 2211 along with the gas to form a gas mixture. After the gas mixture enters the throat section 2212, since the cross-sectional area of ​​the throat section 2212 remains constant with the gas flow, the gas mixture can exchange kinetic energy within the throat section 2212, thus gradually achieving a uniform velocity field distribution during the flow. Subsequently, the gas mixture enters the primary diffuser section 2213, where the pressure increases due to the decrease in flow velocity. Part of the dynamic pressure of the gas mixture becomes static pressure, making the pressure of the gas mixture higher than the pressure of the ejector fluid that just entered the contraction section 2211. The flow velocity of the gas mixture decreases, and at this point, the gas and air are mixed more uniformly. After entering the secondary diffuser section 2214, the static pressure further increases, and the flow velocity of the gas mixture further decreases, resulting in an even more uniform mixture. The design of the primary diffuser section 2213 and the secondary diffuser section 2214 makes the gas and air mixture more uniform, and the gas flow velocity is also significantly reduced. It can be understood that the pressure of the fluid acting vertically on the wall is called static pressure, and the pressure generated by the velocity when the gas mixture flows within the second ejector section 22 of the pipe structure is called dynamic pressure.

[0050] Preferably, the second ejector section 22 and the second mixing section 21 are integrally formed into a single unit through a process, such as die casting or integral casting of metal materials. Furthermore, as... Figures 7 to 9 As shown, multiple second fixing legs 23 are spaced apart at the bottom of the second mixing section 21 and the bottom of the second ejector section 22. For example, the second fixing legs 23 positioned at the throat section 2212 of the second ejector section 22 work together with the two second fixing legs 23 spaced apart at the bottom of the second section 213 to form a tripod shape to support and fix the second burner 2.

[0051] In the above embodiments, the second burner 2 may further include a second burner cap 24 with a second flame hole 241 on its top and a second ignition needle 25 connected to the outer side (the side where the arc is located) of the second mixing section 21. The shape of the second burner cap 24 corresponds to the shape of the second mixing section 21 and covers the second opening 211. A second flame transmission hole 242 is provided on the side wall of the second burner cap 24, and the needle tip of the second ignition needle 25 corresponds to the second flame transmission hole 242.

[0052] In the above embodiments, the stove may further include, for example, Figures 11 to 14 The panel assembly 7 shown has a first combustion hole 71 and a second combustion hole 72. After the second burner 2 is fixed to the cooktop housing 6, the second mixing section 21 of the second burner 2 can pass through the second combustion hole 72, and the second opening 211 of the second mixing section 21 is located in the plane of the first mixing section 12. It can be understood that the second mixing section 21 may not completely pass through the second combustion hole 72, but may pass through a portion of the depth of the first combustion hole 71 and be located within the first combustion hole 71. After the first burner 1 is fixed to the cooktop housing 6, the first mixing section 12 of the first burner 1 can pass through the first combustion hole 71 or the second combustion hole 72, or be located within the first combustion hole 71 or the second combustion hole 72. When the first mixing section 12 is located in the first combustion hole 71, it is in a first position, in which the first burner 1 can be used alone to obtain a smaller heat load. When the first mixing section 12 is located in the second combustion hole 72, it can form a combined burner with the second burner 2 to obtain a larger heat load. Compared to existing technologies, this design achieves optimal power configuration, adapting to various usage scenarios and meeting the requirements of uniform heat for Western cuisine and high-power stir-frying for Chinese cuisine. Furthermore, the panel assembly 7 can also be equipped with a third combustion hole 73, where a conventional burner can be installed.

[0053] According to an exemplary embodiment of panel assembly 7, such as Figure 12As shown, the panel assembly 7 may include, from bottom to top, a panel body 74, a panel reinforcing plate 75, a pot support plate 76, and at least two pot supports 77. The first combustion hole 71 includes a first hole 711, the second combustion hole 72 includes a second hole 721, a third hole 722, and a fourth hole 723, and the third combustion hole 73 includes a fifth hole 731, a sixth hole 732, and a seventh hole 733. The panel body 74 is generally rectangular along a horizontal plane, and has the second hole 721, the seventh hole 733, and a circular hole 741 through which the first base 13 of the first burner 1 passes. The panel reinforcing plate 75 is generally rectangular along a horizontal plane, with multiple mounting features spaced along its periphery, and has the third hole 722, the sixth hole 732, and a clearance portion 751 corresponding to the aforementioned circular hole 741. The clearance portion 751 is an arc-shaped, inwardly recessed groove. The pot support plate 76 is generally rectangular and arranged along the horizontal plane. The pot support plate 76 has a first hole 711, a fourth hole 723, and a fifth hole 731. The pot support plate 76 is spaced apart from the panel reinforcement plate 75 by a certain distance, which allows the first ejector part 11 and the first gas mixing part 12 to move between the panel reinforcement plate 75 and the pot support plate 76, and switch between a first position and a second position. Due to this distance, the pot support plate 76 also has a side facing the panel body 74 (…). Figure 14 The flange extending from the lower side of the pot rack plate 76 shown can cover the lower side of the pot rack plate 76.

[0054] For an exemplary embodiment of at least three pot supports 77, refer to... Figure 12At least two pot supports 77 include a first pot support 771, a second pot support 772, and a third pot support 773. A first hole group 761 is provided on the periphery of the first hole 711 on the pot rack plate 76. When the first pot support 771 is positioned corresponding to the first hole 711, the first pot support 771 passes through the first hole group 761 and connects to the pot rack plate 76 at approximately its middle position. The bottom of the portion passing through the first hole group 761 connects to the panel reinforcement plate 75, thereby allowing a portion of the first pot support 771 to extend out of the pot rack plate 76 to support the pot placed on it, while the other portion is positioned between the pot rack plate 76 and the panel reinforcement plate 75, creating a certain distance between them. Similarly, the pot support plate 76 has a second hole group 762 around the periphery corresponding to the fourth hole 723. When the second pot support 772 is set around the fourth hole 723, the first pot support 771 passes through the second hole group 762. The connection method between the first pot support 771 and the pot support plate 76 and the panel reinforcing plate 75 can be referred to the connection method between the first pot support 771 and the pot support plate 76 and the panel reinforcing plate 75, which will not be repeated here. In addition, the pot support plate 76 has a third hole group 763 around the periphery corresponding to the seventh hole 733. When the third pot support 773 is set around the seventh hole 733, the third pot support 773 passes through the third hole group 763.

[0055] Specifically, such as Figure 13 and Figure 14As shown, the first pot support 771 and the second pot support 772 each include four pot support bodies 774 arranged in a ring at equal intervals. Correspondingly, the first hole group 761 includes four first mounting holes 7611 for mounting the four pot support bodies 774 of the first pot support 771 one by one, and the second hole group 762 includes four second mounting holes 7621 for mounting the four pot support bodies 774 of the second pot support 772 one by one. For the first pot support 771 installed at the first hole 711, the four pot support bodies 774 are arranged at 90° intervals, wherein two opposite pot support bodies 774 are arranged along a first direction (the length direction of the pot support plate 76), and another pair of opposite pot support bodies 774 are arranged along a second direction (the width direction of the pot support plate 76). The first direction is perpendicular to the second direction. The same applies to the four pot support bodies 774 corresponding to the second pot support 772 installed at the fourth hole 723. Thus, the two pot support bodies 774 spaced apart on the first hole 711 and the two pot support bodies 774 spaced apart on the fourth hole 723 extend along the same straight line (i.e., a straight line along the length direction of the pot support plate 76). This allows the two pot support bodies 774 located between the first hole 711 and the fourth hole 723 to be easily integrally formed into a single unit, increasing the strength of the two pot support bodies 774 and reducing manufacturing steps. Similarly, of the two opposing pot support bodies 774 corresponding to the seventh hole 733 and arranged along the length direction of the pot support plate 76, the pot support body 774 located closer to the fourth hole 723 and the pot support body 774 corresponding to the fourth hole 723 and closer to the seventh hole 733 are integrally formed into a single unit. Since this part of the pot support body 774 is integrally formed, it is only connected to the pot support plate 76. The rest of the pot support body 774 can extend to the panel reinforcement plate 75 after passing through the first hole group 761 (first mounting hole 7611), the second hole group 762 (second mounting hole 7621), and the third hole group 763 (third mounting hole 7631). It can be understood that the pot support body 774 can be snap-fitted, plugged in, or otherwise detachably connected to the pot support plate 76 in the first mounting hole 7611, the second mounting hole 7621, and the third mounting hole 7631, respectively.

[0056] To facilitate the disassembly of panel assembly 7, such as Figures 12 to 14As shown, the first pot support 771, the second pot support 772, and the third pot support 773 also include pot support fixing parts 775 corresponding to each pot support body 774. The pot support fixing parts 775 are fixed to the panel reinforcing plate 75 as a whole by welding or other fixing methods. Furthermore, the pot support fixing parts 775 and the pot support body 774 have corresponding installation features, such as snap-fit ​​structures and hooks. When the pot support body 774 and the pot support fixing parts 775 are connected by the installation features, the pot support body 774 can be connected to the panel reinforcing plate 75 through the pot support fixing parts 775, thereby facilitating the disassembly of the panel assembly 7.

[0057] Furthermore, the first base 13 of the first burner 1 is mounted on the bottom shell of the stove. To facilitate the placement of the first ejector 11 and the first gas mixing section 12 between the panel reinforcing plate 75 and the pot support plate 76, the panel body 74 is also provided with a circular hole 741 through which the first base 13 of the first burner 1 passes, and the panel reinforcing plate 75 is provided with a clearance section 751 corresponding to the circular hole 741. The upper part of the first base 13 can pass through the circular hole 741 to place the first ejector 11 and the first gas mixing section 12 between the panel reinforcing plate 75 and the pot support plate 76. It is understood that the clearance section 751 can be along... Figure 12 The horizontally oriented panel reinforcement plate 75 shown has an arc-shaped groove recessed inward along its centerline in the length direction. Further, a first sealing ring 742 is provided on the periphery of the panel body 74 corresponding to the circular hole 741. A second sealing ring 743 is provided on the periphery of the panel body 74.

[0058] Regarding the panel reinforcement plate 75 and the panel body 74, the second burner 2 can be fixed not only to the stove housing 6 but also to either the panel body 74 or the panel reinforcement plate 75. When the second burner 2 is fixed to the panel body 74, mounting holes for the third fixing leg 26 of the second burner 2 can be provided on the panel body 74. When the second burner 2 is fixed to the panel reinforcement plate 75, the diameter of the second hole 721 on the panel body 74 is larger than the diameter of the third hole 722 on the panel reinforcement plate 75, so that the third fixing leg 26 can pass through the second hole 721 and abut against the periphery of the panel reinforcement plate 75 corresponding to the third hole 722. The panel reinforcement plate 75 is provided with fourth mounting holes 752 at intervals corresponding to the third hole 722, each corresponding to one of the third fixing legs 26.
