[0046] It should be noted that these drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0048] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0049] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In the prior art, most gas stoves are equipped with a liquid receiving tray. On the one hand, the liquid receiving tray with uneven shapes will increase the cleaning difficulty of the stove top; on the other hand, the addition of the liquid receiving tray greatly increases the manufacturing cost of the gas stove.

[0051] To solve this technical problem, the embodiments of the present invention provide a gas stove, specifically, an upward air intake gas stove without a liquid receiving tray, as Figures 1 to 11 shown.

[0052] Embodiment 1

[0053] As Figures 1 to 10 shown, in the embodiment of the present invention, an installation structure of a burner base is introduced. The burner includes a burner head 4 and a burner base 2, and the installation structure of the burner base is arranged between the burner head 4 and the burner base 2.

[0054] Specifically, the installation structure of the burner base includes a gas injection structure 43 disposed at the top of the burner head 4 for supporting the burner base 2. There are multiple gas injection structures 43. Specifically, there are at least three gas injection structures 43. The at least three gas injection structures 43 are arranged non-collinearly in the horizontal direction, that is, the projections of the at least three gas injection structures 43 on the horizontal plane form a triangular structure. The burner base 2 is detachably installed on the tops of the at least three gas injection structures 43.

[0055] As Figure 3 and Figure 4 shown, in this embodiment, by providing at least three gas injection structures 43 arranged non-collinearly in the horizontal direction to support the burner base 2, the installation stability of the burner base 2 can be ensured. At the same time, only the necessary gas injection structures 43 are used to support the burner base 2, simplifying the installation structure of the burner base, facilitating the user to clean the panel 1 below the burner base 2, and making the appearance of the burner more regular and beautiful. In addition, when the user needs to clean the panel 1, the burner base 2 together with the burner on it can be removed from the tops of the gas injection structures 43 as a whole, without setting a fixing structure between the burner base 2 and the burner, simplifying the structure of the burner and being beneficial to reducing the production cost of the gas stove.

[0056] The top surface of the gas injection structure 43 is complementary to the bottom shape of the burner base 2 for fitting with the bottom of the burner base 2. That is, the abutting portions of the gas injection structure 43 and the burner base 2 are mutually fitted.

[0057] Preferably, the top surface of the gas injection structure 43 has a microscopic uneven structure, presenting a rough characteristic. Thereby, the friction coefficient between the top of the gas injection structure 43 and the bottom of the burner base 2 can be increased, improving the support stability of the gas injection structure 43 for the burner base 2 and avoiding relative displacement between the burner base 2 and the gas injection structure 43 during use.

[0058] In some preferred embodiments, the surface roughness of the top surface of the gas injection structure 43 is greater than or equal to the surface roughness of the bottom of the burner base 2.

[0059] In this embodiment, the top of the gas injection structure 43 corresponds to the vicinity of the edge of the bottom of the burner base 2, which can further improve the support stability of the burner base 2.

[0060] In some possible embodiments, the top of the gas injection structure 43 is set as a plane, and the corresponding portion of the bottom of the burner base 2 is set as a plane that fits with the top of the gas injection structure 43.

[0061] In some other possible embodiments, one side of the top surface of the gas injection structure 43 away from the axis of the burner base 2 wraps around the corner at the bottom edge of the burner base 2.

[0062] Specifically, in this embodiment, the top surface of the gas injection structure 43 is in contact with at least a part of the outer peripheral surface of the burner base 2, which can further improve the stability of the support of the gas injection structure 43 for the burner base 2, and can prevent the burner base 2 from translating relative to the gas injection structure 43 during the use of the gas stove.

[0063] In some preferred embodiments, a chamfer is provided at the corner between the bottom surface and the outer peripheral surface of the burner base 2. The top surface of the gas injection structure 43 abuts against the bottom surface of the burner base 2, and one side of the top surface of the gas injection structure 43 away from the axis of the burner base 2 wraps around the chamfer at the bottom of the burner base 2.

[0064] Preferably, the chamfer at the corner between the bottom surface and the outer peripheral surface of the burner base 2 is set as a rounded corner, and one side of the top surface of the gas injection structure 43 away from the axis of the burner base 2 is set as an arc-shaped curved surface that fits the rounded corner.

[0065] In this embodiment, the gas injection port of the gas injection structure 43 is arranged on the side of the gas injection structure 43, corresponding to the air inlet end of the ejector tube at the bottom of the burner base 2. Preferably, the gas injection port is coaxial with the ejector tube.

[0066] In this embodiment, the number of ejector tubes at the bottom of the burner base 2 is greater than or equal to the number of gas injection structures 43. Specifically, when the number of ejector tubes is equal to the number of gas injection structures 43, a single gas injection mechanism only has one gas injection port, corresponding to the air inlet end of the ejector tube; when the number of ejector tubes is greater than the number of gas injection structures 43, at least one gas injection structure 43 has a plurality of gas injection ports respectively corresponding to a plurality of ejector tubes. That is, one gas injection structure 43 has at least one gas injection port.

[0067] Preferably, in this embodiment, three ejector tubes are provided at the bottom of the burner base 2, and three gas injection structures 43 corresponding to the ejector tubes at the bottom of the burner base 2 are provided, and each gas injection structure 43 has one gas injection port.

[0068] In this embodiment, the burner base 2 is disc-shaped. Horizontally, these three gas injection structures 43 will not be simultaneously in the same semi-circular area of the disc-shaped burner base 2. That is, horizontally, the gas injection structures 43 are always distributed in two opposite semi-circular areas of the disc-shaped burner base 2, so as to achieve stable support for the burner base 2.

[0069] Specifically, in this embodiment, there are three gas injection structures 43. The projections of the three gas injection structures 43 on the horizontal plane form a triangular area, and the axis of the burner base 2 passes through the middle of this triangular area. That is, the three gas injection structures 43 are distributed at different positions of the burner base 2, and the maximum arc length corresponding to any two gas injection structures 43 does not exceed a semi-circle. That is, the central angle formed by the connecting lines of any two gas injection structures 43 and the center of the burner base 2 is less than 180 degrees, thus forming a stable triangular support structure. This distribution does not require the gas injection structures 43 to be evenly arranged, but ensures the support stability of the burner base 2.

[0070] Preferably, the distances from the gas injection structures 43 to the center of the burner base 2 can be the same or different.

[0071] In this embodiment, the burner base 2 includes an inner ring mixing chamber 21 and an outer ring mixing chamber 22. The ejector pipe includes a first ejector pipe 23 communicating with the inner ring mixing chamber 21 and a second ejector pipe 24 communicating with the outer ring mixing chamber 22. The air inlet ends of the first ejector pipe 23 and the second ejector pipe 24 are both arranged close to the outer periphery of the outer ring mixing chamber 22, and the gas injection structures 43 corresponding to the air inlet ends of the first ejector pipe 23 and the second ejector pipe 24 are both arranged directly below the outer ring mixing chamber 22. That is, the gas injection structures 43 support the burner base 2 from the bottom of the outer ring mixing chamber 22.

[0072] As Figure 9 shown, in this embodiment, there are two second ejector pipes 24, which are arranged on opposite sides of the outer ring mixing chamber 22. The air inlet ends of the two second ejector pipes 24 face the same direction, and the air inlet end of the first ejector pipe 23 faces the opposite direction to the air inlet ends of the second ejector pipes 24; or the air inlet ends of the two second ejector pipes 24 face opposite directions. Thus, it can be avoided that the air inlet ends of the two second ejector pipes 24 and one first ejector pipe 23 are concentrated on the same side of the burner base 2, ensuring the support stability of the burner base 2.

[0073] Preferably, the first ejector pipe 23 and the second ejector pipe 24 extend along the tangents of the inner ring mixing chamber 21 and the outer ring mixing chamber 22 respectively. In this embodiment, the statement that "the first ejector pipe 23 extends along the tangent of the inner ring mixing chamber 21" specifically means that the extending direction of the first ejector pipe 23 is consistent with the extending direction of a tangent of the inner ring mixing chamber 21; the statement that "the second ejector pipe 24 extends along the tangent of the outer ring mixing chamber 22" specifically means that the extending direction of the second ejector pipe 24 is consistent with the extending direction of a tangent of the outer ring mixing chamber 22.

[0074] Preferably, the first ejector pipe 23 and the second ejector pipe 24 are parallel to each other.

[0075] As Figure 9As shown, in this embodiment, the air inlet ends of the two second ejector pipes 24 face in opposite directions, and the first ejector pipe 23 and the second ejector pipe 24 are parallel to each other. Among them, the first ejector pipe 23 is arranged close to one of the second ejector pipes 24 with the same orientation as it.

[0076] Specifically, the air inlet end of one second ejector pipe 24 faces the first direction, and the air inlet end of the other second ejector pipe 24 faces the second direction, and the first direction is opposite to the second direction. The air inlet end of the first ejector pipe 23 faces the first direction, and the first ejector pipe 23 is arranged close to the second ejector pipe 24 with the air inlet end facing the first direction.

[0077] In some specific embodiments, the air outlet end of the second ejector pipe 24 extends along the circumferential direction of the outer ring mixing chamber 22. Along the direction away from the air inlet end of the second ejector pipe 24, the bottom of the air outlet end of the second ejector pipe 24 gradually rises, so that the guiding effect on the mixture of gas and primary air can be improved.

[0078] In this embodiment, by setting the air inlet ends of the two second ejector pipes 24 to face in opposite directions, the mixture of gas and primary air can spiral upward in the outer ring mixing chamber 22, improving the smoothness of guiding the mixture, ensuring the ejecting effect on the primary air, and improving the uniformity of the mixture of gas and primary air, thereby improving the combustion effect of the gas.

[0079] By setting the first ejector pipe 23 to be arranged close to one of the second ejector pipes 24 with the same orientation as it, it can ensure that there is enough space between the air outlet end of the second ejector pipe 24 with the air inlet end facing the second direction and the air inlet end of the first ejector pipe 23 to arrange the gas injection structure 43, avoiding interference between the air inlet end of the first ejector pipe 23 and the air outlet end of the second ejector pipe 24.

[0080] Preferably, in this embodiment, a nozzle 431 is installed at the gas injection port of the gas injection structure 43, and the nozzle 431 is coaxial with the air inlet end of the ejector pipe.

[0081] In this embodiment, an inner fire cap 211 and an outer fire cap 221 are respectively buckled on the top of the inner ring mixing chamber 21 and the top of the outer ring mixing chamber 22, and the mixture of gas and air burns on the inner fire cap 211 and the outer fire cap 221.

[0082] In this embodiment, a circumferential positioning structure is provided between the burner head 4 and the fire cap seat 2. The circumferential positioning structure is used to improve the accuracy of the installation angle of the fire cap seat 2, ensure that the air inlet end of the ejector pipe corresponds to the gas injection port of the gas injection structure 43 one by one, and enable the burner to work stably.

[0083] In some possible embodiments, a first positioning portion 251 is provided on the burner base 2. Along the installation direction of the burner base 2, the first positioning portion 251 is sleeved with the combustion control assembly on the burner head 4. Specifically, the first positioning portion 251 is sleeved in the middle of the combustion control assembly, enabling the combustion control assembly to function properly.

[0084] Specifically, the first positioning portion 251 is a plate-shaped structure extending along the radial direction of the burner base 2. A first positioning hole and / or a first positioning groove 252 for sleeving the outer periphery of the combustion control assembly are provided on the first positioning portion 251.

[0085] In this embodiment, the combustion control assembly includes an ignition needle 41 and / or a thermocouple 42, and a first positioning portion 251 corresponding to the ignition needle 41 and / or the thermocouple 42 is provided on the burner base 2.

[0086] Preferably, the ignition needle 41 and the thermocouple 42 are close to each other. A first positioning groove 252 is provided on the first positioning portion 251. The first positioning groove 252 includes two continuous recessed portions, and the two recessed portions are respectively in contact with the outer peripheral walls of the ignition needle 41 and the thermocouple 42.

[0087] In some specific embodiments, the outer ring mixing cavity 22 is arranged around the inner ring mixing cavity 21, and there is an interval between the outer periphery and the inner periphery of the inner ring mixing cavity 21. An ignition needle 41 and a thermocouple 42 are provided on the burner head 4, and the ignition needle 41 and the thermocouple 42 correspond to the interval between the inner ring mixing cavity 21 and the outer ring mixing cavity 22.

[0088] The first positioning portion 251 is plate-shaped, extending along the radial direction of the burner base 2, and at least partially extending between the inner ring mixing cavity 21 and the outer ring mixing cavity 22. A first positioning groove 252 is provided on the first positioning portion 251, surrounding the ignition needle 41 and the thermocouple 42. The first positioning groove 252 includes a first recessed portion corresponding to the ignition needle 41 and a second recessed portion corresponding to the thermocouple 42, and the first positioning groove 252 cooperates with the ignition needle 41 and the thermocouple 42 simultaneously.

[0089] Preferably, the first positioning portion 251 includes a first part 2511 arranged around the outer periphery of the inner ring mixing cavity 21 and a second part 2512 connected between the first part 2511 and the outer ring mixing cavity 22. The first positioning groove 252 is provided at the connection between the first part 2511 and the second part 2512, protruding in a direction away from the axis of the burner base 2.

[0090] Specifically, as Figure 9 shown, the first part 2511 of the first positioning portion 251 is an arc-shaped structure, the inner periphery of the first part 2511 is connected to the outer peripheral wall of the inner ring mixing cavity 21, and the second part 2512 is strip-shaped.

[0110] Embodiment Two

[0111] As Figure 1As shown, in an embodiment of the present invention, a gas stove is further provided. The gas stove includes the burner in the first embodiment above, and further includes a panel 1 and a housing 10.

[0112] The panel 1 is installed on the top of the housing 10, and a cavity is formed between the panel 1 and the housing 10. The burner head 4 is installed in the cavity. Specifically, the burner head 4 is installed at the bottom of the housing 10 and is fixedly connected to the housing 10 through connection structures such as screws, bolts, and buckles.

[0113] In this embodiment, the burner head 4 mainly consists of a gas injection structure 43, a gas distribution pipe, and a bracket. The gas distribution pipe is used to transport gas from the gas valve to the gas injection structure 43. Both the gas distribution pipe and the gas injection structure 43 are fixed on the bracket, and the bracket is fixedly connected to the housing 10.

[0114] An installation opening 12 is formed on the panel 1. The burner head 4 is installed below the panel 1, and the gas injection structure 43 at the top of the burner head 4 extends upward through the installation opening 12 on the panel 1, and the top of the gas injection structure 43 extends above the panel 1. The burner cap base 2 is installed on the gas injection structure 43 and is disposed opposite to the panel 1. Thus, it is beneficial to reduce the size of the installation opening 12 formed on the panel 1 and improve the aesthetics of the panel 1.

[0115] As Figure 5 and Figure 6 shown, in this embodiment, two installation openings 12 are formed on the panel 1. Among them, the gas injection structure 43 corresponding to the air inlet end of the first injection pipe 23 and the gas injection structure 43 corresponding to the air inlet end of the second injection pipe 24 whose air inlet end faces the first direction are arranged in the same installation opening 12, and the gas injection structure 43 corresponding to the air inlet end of the injection pipe whose air inlet end faces the second direction is arranged in the other installation opening 12.

[0116] Preferably, in this embodiment, the thermocouple 42 and the ignition pin 41 are arranged in one of the installation openings 12, and the columnar protrusion 26 is arranged in the other installation opening 12.

[0117] Preferably, the thermocouple 42 and the ignition pin 41 correspond to the installation opening 12 with one gas injection structure 43 inside, and the columnar protrusion 26 corresponds to the installation opening 12 with two gas injection structures 43 inside.

[0118] In this embodiment, a decorative cover 11 for shielding the installation opening 12 is installed at the installation opening 12. The decorative cover 11 is provided with a first opening 111 complementary to the outer peripheral shape of the gas injection structure 43 and a second opening 112 complementary to the outer peripheral shape of the installation part.

[0119] Preferably, in this embodiment, the decorative cover 11 includes a covering mounting opening 12, a plate portion that fits with the panel 1, and a cylindrical portion that extends vertically downward from the middle of the plate portion and whose outer periphery fits with the inner wall of the mounting opening 12. The first opening 111 and / or the second opening 112 are provided in the middle of the plate portion.

[0120] In some possible embodiments, the columnar protrusion 26 is also used for positioning the decorative cover 11. Specifically, the lower end of the columnar protrusion 26 passes through the second opening 112 and is detachably connected to the burner head 4. The portion of the columnar protrusion 26 located above the decorative cover 11 fits with the top of the decorative cover 11 on the outer periphery of the second opening 112. Thus, the decorative cover 11 can be limited on the panel without setting additional mounting structures such as screws.

[0121] Preferably, the lower end of the columnar protrusion 26 and the burner head are in threaded connection.

[0122] Preferably, the upper end of the columnar protrusion 26 fits with the bottom of the burner cap seat 2, that is, the columnar protrusion can also support the burner cap seat, further improving the mounting stability of the burner cap seat.

[0123] Preferably, the outer diameter of the support ring 31 is greater than or equal to the maximum distance between the edge of the mounting opening 12 and the axis of the burner cap seat 2, that is, the projection of the outer edge of the support ring 31 on the panel 1 surrounds outside the mounting opening 12. Thus, the overall formed by the wok support 3 and the burner cap seat 2 can cover the mounting opening 12 on the panel 1, further improving the aesthetics of the gas stove.

[0124] Preferably, the outer diameter of the support ring 31 is greater than or equal to the maximum distance between the edge of the decorative cover 11 and the axis of the burner cap seat 2, so that the decorative cover 11 will not be exposed, or only a small part of the decorative cover 11 will be exposed from the gap between the inner ring mixing chamber 21 and the outer ring mixing chamber 22, improving the visual experience of the user.

[0125] Preferably, in this embodiment, along the direction away from the axis of the burner cap seat 2, the support ring 31 extends obliquely downward, and / or the outer periphery of the support ring 31 extends vertically downward, which can further enhance the shielding effect of the support ring 31 on the decorative cover 11 and prevent the user from directly observing the decorative cover 11 from the side of the wok support 3.

[0126] With the above settings, the outer edge of the support ring 31 can extend to the outer periphery of the decorative cover 11, and the outer edge of the support ring 31 is close to the panel 1. Thus, it can prevent users from directly observing the decorative cover 11 from the obliquely front of the gas stove, improving the user's visual experience. In addition, under the support of the burner base 2 on the pot support 3, the outer edge of the support ring 31 is spaced from the panel 1, so that the primary air inhaled through the ejector tube during the gas injection process and part of the secondary air required during the gas combustion process can enter through the gap between the support ring 31 and the panel 1, ensuring the combustion effect.

[0127] In some preferred embodiments, along the direction away from the axis of the burner base 2, the support ring 31 has a first extension section 312 that extends upward and obliquely away from the axis of the burner base 2, and a second extension section 313 that extends vertically downward from the outer edge of the support ring 31. The setting of the first extension section 312 can facilitate the convergence of the heat of the flame combustion to the bottom of the cookware, improving the utilization rate of the heat. At the same time, the setting of the second extension section 313 can also ensure the shielding effect on the decorative cover 11, ensuring aesthetics.

[0128] In this embodiment, the pot support 3 is coaxial with the burner base 2.

[0129] In this embodiment, a first support leg 32 is provided on the support ring 31. The first support leg 32 is arranged at the top of the support ring 31, and the pot support 3 supports the cookware through the first support leg 32.

[0130] In this embodiment, a plurality of first support legs 32 are arranged along the circumferential direction of the support ring 31 at equal intervals, ensuring the support stability of the cookware. Preferably, four first support legs 32 are provided, and the four first support legs 32 are arranged along the circumferential direction of the support ring 31 at equal intervals.

[0131] In some specific embodiments, the first support leg 32 is a plate-shaped one that extends radially along the support ring 31, and a supporting portion that extends toward the axis of the support ring 31 is provided at its top. The top of the supporting portion is set as an inclined surface that extends downward and obliquely toward the axis of the support ring 31.

[0132] In some possible embodiments, no second support leg is provided below the support ring 31, or a second support leg is provided below the support ring 31 and the second support leg is hidden by the support ring. Specifically, when the user is using it normally, the second support leg is not visible, making the pot support form a suspended effect, improving the user's visual experience.

[0133] In some other possible embodiments, a second support leg 33 is provided at the bottom of the support ring 31, and the bottom of the second support leg 33 is close to the panel 1 of the gas stove.

[0134] Specifically, the second supporting leg 33 can assist the burner base 2 in supporting the support ring 31. When the weight of the cookware supported on the pot support 3 is relatively large, the support ring 31 will deform, enabling the panel 1 to provide a supporting force to the support ring 31 through the second supporting leg 33, thereby improving the supporting stability of the pot support 3 for the cookware.

[0135] Preferably, the bottom of the second supporting leg 33 is in contact with the panel 1 of the gas stove. And when there is no cookware on the pot support 3, the second supporting leg 33 does not exert pressure on the panel 1. Or, there is a gap between the bottom of the second supporting leg 33 and the panel 1 of the gas stove.

[0136] Through the above settings, when there is no cookware on the pot support 3, or when the cookware supported on the pot support 3 is relatively light, the bottom of the second supporting leg 33 will not exert pressure on the panel 1, or even will not come into contact with the panel 1, which can avoid the situation that obvious indentations appear on the panel 1 due to the long-term extrusion of the second supporting leg 33 on the panel 1. At the same time, the setting of the second supporting leg 33 can further prevent the cookware supported on the pot support 3 from overturning, improving the working stability of the gas stove.

[0137] Preferably, in this embodiment, there is a gap between the bottom of the second supporting leg 33 and the panel 1 of the gas stove.

[0138] In this embodiment, the second supporting leg 33 is a plate-shaped one extending along the radial direction of the support ring 31.

[0139] Preferably, in this embodiment, a plurality of second supporting legs 33 are provided corresponding one-to-one with the first supporting legs 32.

[0140] Preferably, the second supporting leg 33 and the first supporting leg 32 are integral parts formed on the support ring 31.

[0141] Preferably, in this embodiment, a U-shaped member 34 is provided at the bottom of the second supporting leg 33. The U-shaped member 34 is made of a flexible material and is fixed at the bottom of the second supporting leg 33, covering the bottom of the second supporting leg 33 therein. The bottom of the second supporting leg 33 contacts the panel 1 through the U-shaped member 34, which can avoid scratching the panel 1 when the bottom of the second supporting leg 33 contacts the panel 1.

[0142] In this embodiment, the U-shaped member 34 can be made of silicone material or heat-resistant rubber material.

[0143] Preferably, in this embodiment, the bottom of the second support leg 33 is lower than the bottom of the burner base 2. Thus, after the user removes the burner base 2 and the pot support 3 and places them, the second support leg 33 can support the whole formed by the burner base 2 and the pot support 3, so that the whole formed by the burner base 2 and the pot support 3 can be kept stable, and it can be avoided that the bottom of the burner base 2 contacts the support surface for placing the burner base 2 and the pot support 3, and dirt can be prevented from entering at the ejector pipe.
