Description

Technical Field

[0001] The invention relates to the field of burners, in particular to a burner head which can rotate as a whole. Background Art

[0002] At present, the trend of household kitchen gas stoves is to embed the stove under the panel so that the stove surface and the stove panel are on the same plane. The stove with a cover structure looks beautiful and convenient to use. However, when cooking food in the Chinese style of boiling and frying, the gas stove often becomes dirty due to the overflow of food solution into the gap between the stove and the panel, so it needs to be cleaned daily. However, since the burner is fixedly installed on the gas stove, the gap between the bottom of the burner and the panel is blocked, making the gas stove difficult to clean. In addition, most of the current gas stoves are fixedly installed with two burners, but the distance between the two burners is fixed. Therefore, when the user needs to cook with a larger diameter pot, it is easy for the gas stove to not be able to accommodate and use two pots at the same time, and the pot must be replaced with a smaller diameter pot or even used one by one, which increases the cooking time and reduces the convenience of cooking.

[0003] Therefore, the applicant applied for a patent on January 16, 2018, with the title "New Burner" and the patent number "CN201820072247.8" to solve the above problems. However, during the implementation of the structure, the gap at the connection position is prone to air leakage, so a very complex structure is required at the connection position to achieve the needs of sealing and rotation, which ultimately leads to increased production costs, so further improvement is needed. Summary of the invention

[0004] The purpose of the present invention is to solve the above existing problems and provide a burner head which is simple in structure and reasonable and can rotate as a whole, and its function is to solve the problem of gas leakage caused by the gap at the rotating position of the burner head.

[0006] The stove equipped with the burner head of this structure can realize circular rotation and improve the air tightness of the burner head, preventing air leakage and the like from occurring. It is convenient for the user to freely rotate the burner head seat and the ejector tube along the rotating shaft ejector seat as the center after use, so that the user can clean the entire stove panel, reduce dead corners, keep the stove clean and hygienic, and prevent food residues from attracting cockroaches and breeding bacteria. When the stove uses two burners at the same time, the burner head seat and the ejector tube can be rotated according to the diameter of the pot, so that the distance between the two burners on the stove is increased, so that the user can use two large-diameter pots for cooking at the same time, thereby improving the efficiency and convenience of the stove.

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 5 As shown, a burner head that can rotate as a whole comprises a stove 1, on which an ejector tube 2 is arranged, one end of which is connected to a suspended burner head seat 3, on which a burner 4 is installed, and the other end of which is connected to a rotating shaft ejector seat 5, which is rotatably connected to the stove 1 along the central axis, and the burner head seat 3 realizes circular rotation with the rotating shaft ejector seat 5 as the central axis through the ejector tube 2;

[0026] The stove equipped with the burner head of this structure can realize circular rotation and improve the air tightness of the burner head, preventing air leakage and the like from occurring. It is convenient for the user to freely rotate the burner head seat 3 and the ejector tube 2 along the rotating shaft ejector seat 5 as the center after use, so that the user can clean the entire stove panel, reduce dead corners, keep the stove clean and hygienic, and prevent food residues from attracting cockroaches and breeding bacteria. When the stove uses two burners at the same time, the burner head seat 3 and the ejector tube 2 can be rotated according to the diameter of the pot, so that the distance between the two burners 4 on the stove is increased, so that the user can use two large-diameter pots for cooking at the same time, thereby improving the efficiency and convenience of the stove.

[0027] The burner 4 comprises a fire cover seat 41 and a fire distribution cover 42 . The fire cover seat 41 and the fire distribution cover 42 are sequentially mounted on the burner seat 3 . In addition, the burner seat 3 is integrally connected with the ejector tube 2 .

[0028] The rotating shaft ejector seat 5 includes a seat body shell 6, which is integrally connected to the ejector tube 2, and a rotating shaft device 7 is vertically connected inside the seat body shell 6. An air inlet 8 is provided at the lower end of the rotating shaft device 7, and an air outlet 9 is provided at the upper end. A jet nozzle 10 is horizontally installed on the air outlet 9 facing the air inlet end of the ejector tube, and a gas channel 11 connecting the air inlet 8 and the air outlet 9 is provided inside the rotating shaft device 7; the rotating shaft device 7 supports the seat body shell 6 to enable it to rotate, thereby driving the burner seat 3 and the ejector tube 2 to rotate in a circle. Since the ejector tube 2 is horizontally arranged, the horizontally arranged jet nozzle 10 can spray the gas into the ejector tube 2, which has a simple structure and is easy to install. The jet nozzle 10 is installed at a position close to the axis center, so there is no need to adjust the structure of the burner head, reducing the gap in the mixed gas flow path that is increased to achieve rotation, and avoiding problems such as gas leakage.

[0029] In addition, since the injection nozzle 10 is installed in the seat shell 6, compared with other upper air inlet burners, the injection nozzle 10 is not exposed to the outside, so it will not be affected by other factors and cause safety hazards (for example, some cockroaches and other insects enter through the burner throat in front of the injection nozzle 10).

[0030] In addition, a circular LCD screen 16 can be installed on the upper end surface of the seat shell 6, and the display interface (fire power, gear position and other information) originally installed on the panel 102 can be integrated into the LCD screen 16, so that the burner can be controlled and adjusted at any rotation angle to ensure that the displayed information is always in the front direction. The LCD screen 16 makes the outer surface of the rotating shaft ejector seat 5 more beautiful.

[0031] The rotating shaft device 7 includes an upper shaft sleeve 71 and a lower shaft sleeve 72. The lower shaft sleeve 72 is inserted into the upper shaft sleeve 71 and forms a hollow gas passage 11. The upper shaft sleeve 71 can rotate relative to the lower shaft sleeve 72. The top of the upper shaft sleeve 71 is fixedly connected to the base shell 6. The air outlet 9 is opened at the upper end of the upper shaft sleeve 71 and is equipped with a spray nozzle 10. The lower shaft sleeve 72 is connected to the inner cavity of the stove 1, and the air inlet 8 is opened on the lower shaft sleeve 72.

[0032] During use, since the ejector tube will rotate in a circle, the injection nozzle 10 connected to the air inlet end of the ejector tube needs to rotate together to ensure that the central axis of the injection nozzle 10 overlaps with the central axis of the ejector tube. Therefore, the rotating shaft device 7 is divided into two major parts: an upper shaft sleeve 71 and a lower shaft sleeve 72. The lower shaft sleeve 72 is fixed to facilitate the connection of the gas hose. During the rotation of the burner head, the gas hose will not be entangled outside the rotating shaft device 7 due to rotation, and the upper shaft sleeve 71 rotates relative to the lower shaft sleeve 72. Since the upper shaft sleeve 71 is fixedly connected to the base body shell 6 and the injection nozzle 10 is installed on the upper shaft sleeve 71, the rotation angle of the upper shaft sleeve 71 can be consistent with the rotation angle of the injection nozzle 10. The rotating shaft device 7 of this structure realizes the functions of gas guiding, sealing and rotation.

[0033] An annular outer bevel 721 is provided at the upper end of the outer wall of the lower shaft sleeve 72, and an annular inner bevel 711 is provided on the inner wall of the upper shaft sleeve 71. When the lower shaft sleeve 72 is inserted into the upper shaft sleeve 71, the annular inner bevel 711 and the annular outer bevel 721 are tightly pressed against each other, so that the upper shaft sleeve 71 presses down the lower shaft sleeve 72 under the action of gravity. The two bevels are closely matched to achieve the most basic sealing effect, which can ensure that when the upper shaft sleeve 71 rotates relative to the lower shaft sleeve 72, any contact position can achieve sealing, thereby improving the airtight reliability of the rotating shaft device 7.

[0034] The stove 1 includes a bottom shell 101 and a panel 102. A through hole 103 is opened on the panel 102. The base shell 6 is arranged above the through hole 103. A rotating shaft device 7 is installed below the through hole 103. The rotating shaft device 7 extends above the through hole 103 and is fixedly connected to the base shell 6, so that most of the structure of the stove head is embedded in the bottom shell 101, so that the structure visible to the user on the panel 102 is simplified to the maximum extent, thereby improving the aesthetics of the stove.

[0035] The rotating shaft device 7 also includes a rotating motor 73, a horizontal output end of the rotating motor 73 is connected to a reducer 74, a lower shaft sleeve 72 is installed on the upper end surface of the reducer 74, a rotating shaft 741 of the reducer 74 penetrates the lower shaft sleeve 72 and is driven and connected to the upper shaft sleeve 71, and the rotation of the burner head can be automated by the rotating motor 73, thereby improving the grade of the stove.

[0036] A plurality of support legs 31 extend along the circumferential direction on the burner seat 3, a countersunk hole 32 is provided at the end of the support leg bracket 31, a cylindrical support leg 12 is slidably installed in the countersunk hole 32, a step surface 321 is provided in the countersunk hole 32, and a limiting step surface 121 is provided on the support leg 12 for limiting cooperation with the step surface 321, a return spring 13 is sleeved on the support leg 12, and the two ends of the return spring 13 are respectively in contact with the step surface 321 and the limiting step surface 121. Since the burner seat 3 needs to rotate along the circumference of the rotating shaft ejection seat 5, the burner seat 3 is suspended so that it will not rub or collide with the panel during rotation, so the pot can be supported by the support legs 12 and erected above the burner 4.

[0037] During use, after the position of the burner seat 3 is confirmed, the cookware is placed on a plurality of legs 12 and erected. The legs 12 slide downward under the weight of the cookware, and the return springs 13 are compressed by the limiting step surface 121 until the bottom of the legs 12 touches the panel 102 to achieve support. When the burner seat 3 needs to be rotated, the cookware is lifted up, and the legs 12 are pushed and slid upward under the tension of the return springs 13, so that the bottom of the legs 12 leaves the panel and is suspended from the panel together with the burner seat 3. The burner seat 3 and the ejector tube 2 are driven manually or electrically to achieve circular rotation. During the whole process, the burner will not scratch the panel due to rotation, causing wear and abnormal noise.

[0038] An annular sealing ring 14 is installed in the through hole 103, and the annular sealing ring 14 fits tightly with the hole wall. When the stove head is cleaned, or other food solutions overflow from the pot to the panel, the annular sealing ring 14 can prevent the liquid from flowing into the bottom of the panel and causing accumulation of food residue. After long-term use, odor will be generated, attracting cockroaches and insects, etc., which are prone to breed bacteria and affect food hygiene and safety.

[0039] Structural reinforcement ribs 15 are integrally extended on both sides of the connection between the seat shell 6 and the ejector tube 2 .

[0040] The central axis of the injection nozzle 10 overlaps with the central axis of the ejector tube 2, so that the injection nozzle 10 can be aligned with the central part of the air inlet end of the ejector tube 2, so that the injected gas can enter the ejector tube 2 and flow toward the burner seat 3, reducing gas overflow and improving utilization efficiency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
