Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a fire distributor, a burner and a gas stove. Background Art

[0002] With the improvement of living standards, users have put forward higher requirements for cooking, requiring greater firepower and more uniform firepower, so they put forward higher requirements for burners. Enterprise design needs to optimize the burner structure, and at the same time, they also need to consider cost reduction. After years of development, the structure of ordinary concentric two-ring direct fire burners has basically been in a better state, and there is not much room for optimization. Therefore, burners with eccentric circle design (that is, the outer ring air inlet and the inner ring air inlet are not at the same center) began to appear on the market. However, such a structure will bring about the problem of uneven fire in the outer ring. Therefore, how to solve the problem of uneven flame of eccentric circle burners is a technical difficulty that needs to be overcome.

[0003] To address the problem of uneven flames, existing burner products on the market employ a diverter baffle installed above the outer ring air inlet to divert the gas flow, thereby evenly distributing the gas and improving flame uniformity. However, the small distance between the diverter baffle and the outer ring air inlet creates excessive resistance to the gas from the diverter baffle, leading to insufficient primary air intake, incomplete combustion, high flue gas levels, and reduced thermal efficiency. While reducing the area of the diverter baffle can reduce resistance to the gas, a diverter with an area that is too small will not adequately divert the gas, resulting in uneven outer ring flame distribution.

[0004] Therefore, in the urgent need of a kind of fire distributor to address the problems referred to above. Utility Model Content

[0005] The present invention aims to solve, at least to a certain extent, one of the problems existing in the existing related technologies. To this end, the present invention proposes a fire divider. By separately providing an outer ring air inlet hole for the outer ring fire divider groove and separately providing an inner ring air inlet hole for the inner ring fire divider groove, there is no need to provide a diversion air duct on the fire divider, which reduces the material used in the fire divider and thus reduces the cost. In addition, the outer ring flame has better stability and uniformity.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A fire divider comprises a fire divider base and a diverter member, an outer ring fire divider groove and an inner ring fire divider groove are provided on the upper side of the fire divider base, the inner ring fire divider groove is located on the inner side of the outer ring fire divider groove, an outer ring air inlet hole is provided at the bottom of the left end of the outer ring fire divider groove, and an inner ring air inlet hole is provided at the bottom of the inner ring fire divider groove, the bottom of the outer ring fire divider groove is extended upward from the left end of the outer ring fire divider groove to the right end of the outer ring fire divider groove, and the diverter member is provided on the upper part of the outer ring fire divider groove and above the outer ring air inlet hole.

[0008] Optionally, the diverter is a fan ring and the middle portion is located above the outer ring air inlet hole.

[0009] Optionally, the central angle of the diverter is 180°.

[0010] Optionally, it further includes a first mounting portion, which is arranged on an inner wall of the outer ring fire dividing groove, and the side surface of the first mounting portion facing the other inner wall of the outer ring fire dividing groove is obliquely extended along the flow direction of the gas in the inner ring fire dividing groove, and the diverter is installed on the first mounting portion.

[0011] Optionally, a liquid-blocking protrusion extending upward is further provided on the peripheral side of the outer ring air inlet hole, and a liquid storage groove is formed between the liquid-blocking protrusion and the outer ring fire-dividing groove.

[0012] Optionally, a second mounting portion for mounting an outer fire cover of a burner is further provided in the outer ring fire dividing groove, and the second mounting portion is located above the outer ring air inlet hole and / or at an end opposite to the outer ring air inlet hole.

[0013] On the other hand, the utility model provides a burner, including the above-mentioned flame divider, and also including an outer fire cover and an inner fire cover installed on the upper side of the flame divider base, the outer fire cover is arranged on the outer ring flame divider groove, and the inner fire cover is arranged on the inner ring flame divider groove.

[0014] Optionally, a plurality of spaced-apart outer ring fire hole groups are provided on the circumferential side of the outer fire cover, a pot support avoidance area is provided between two adjacent outer ring fire hole groups, and the outer ring fire hole group includes a plurality of adjacently arranged outer ring fire holes.

[0015] In another aspect, the present invention provides a gas stove comprising the burner mentioned above.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] The flame divider provided by the present invention extends the bottom of the outer ring flame divider groove upward from the left end of the outer ring flame divider groove to the right end of the outer ring flame divider groove, thereby ensuring a relatively large distance between the outer ring air inlet hole and the diverter, thereby reducing the resistance of the diverter to the outer ring air flow. This is conducive to the outer ring air flow having sufficient space to convert the velocity field into a pressure field, thereby ensuring that the gas in the outer ring flame divider groove has sufficient static pressure, thereby ensuring the stability and uniformity of the outer ring flame. In addition, by separately providing an outer ring air inlet hole for the outer ring flame divider groove and a separate inner ring air inlet hole for the inner ring flame divider groove, it is unnecessary to provide a diverter air duct on the flame divider, thereby reducing the material used in the flame divider and thus reducing the cost.

[0031] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0032] Please refer to Figure 1-Figure 7 The utility model provides a fire divider, including a fire divider base 50 and a diverter 4. An outer ring fire divider groove 501 and an inner ring fire divider groove 502 are provided on the upper side of the fire divider base 50. The inner ring fire divider groove 502 is located on the inner side of the outer ring fire divider groove 501. An outer ring air inlet hole 51 is provided at the bottom of the left end of the outer ring fire divider groove 501, and an inner ring air inlet hole 52 is provided at the bottom of the inner ring fire divider groove 502. The bottom of the outer ring fire divider groove 501 extends upward from the left end of the outer ring fire divider groove 501 to the right end of the outer ring fire divider groove 501. The diverter 4 is provided on the upper part of the outer ring fire divider groove 501 and is located above the outer ring air inlet hole 51.

[0033] The flame divider 5 provided by the present invention is configured to extend the bottom of the outer ring flame divider groove 501 upwardly and tilted from the left end of the outer ring flame divider groove 501 to the right end of the outer ring flame divider groove 501, so that there is a relatively large distance between the outer ring air inlet hole 51 and the diverter 4, thereby reducing the resistance of the diverter 4 to the outer ring air inlet airflow, which is conducive to the outer ring airflow having sufficient space to convert the velocity field into a pressure field, thereby ensuring that the gas in the outer ring flame divider groove 501 has sufficient static pressure, thereby ensuring the stability and uniformity of the outer ring flame. In addition, by separately providing the outer ring air inlet hole 51 for the outer ring flame divider groove 501 and separately providing the inner ring air inlet hole 52 for the inner ring flame divider groove 502, there is no need to provide a diversion air duct on the flame divider 5, which reduces the material used in the flame divider 5 and thus reduces the cost.

[0034] Optionally, the diverter 4 is a fan ring and the middle part is located above the outer ring air inlet hole 51, so that the gas entering the outer ring gas distribution groove from the outer ring air inlet hole 51 can be evenly diverted to various positions of the outer ring flame distribution groove 501, thereby further improving the uniformity of the outer ring flame.

[0035] Optionally, the central angle of the diverter 4 is 180°, so that the diverter 4 can extend to the middle of the outer ring fire diversion groove 501 to improve the diversion effect of the gas.

[0036] Optionally, a first mounting portion 551 is further included. The first mounting portion 551 is disposed on one inner sidewall of the outer ring fire diversion groove 501, and the side surface of the first mounting portion 551 facing the other inner sidewall of the outer ring fire diversion groove 501 extends obliquely along the flow direction of the gas in the inner ring fire diversion groove 502. This reduces obstruction of the gas by the first mounting portion 551 and reduces resistance to the gas flow. The flow diverter 4 is mounted on the first mounting portion 551, thereby achieving installation of the flow diverter 4 in the outer ring fire diversion groove 501.

[0037] Furthermore, a first mounting hole 55 is defined on the first mounting portion 551 , and the diverter 4 is fixed to the first mounting portion 551 by passing the first screw 3 through the first mounting hole 55 .

[0038] Optionally, a liquid retaining protrusion 54 extending upward is further provided around the outer ring air inlet hole 51, and a liquid storage groove 56 is formed between the liquid retaining protrusion 54 and the outer ring fire dividing groove 501 to collect the soup in the fire divider 5. When the stove is used to burn and the temperature rises, the accumulated soup water will be evaporated. After using it for a period of time, the user can remove the outer fire cover 2 and perform a deep cleaning. In this way, it can prevent the soup overflowing during cooking from entering the fire divider 5 and then flowing to the mating surface between the burner and the outer ring air inlet hole 51, causing the burner to rust.

[0039] Optionally, a second mounting portion 531 for mounting the outer fire cover 2 of the burner is further provided in the outer ring fire dividing groove 501. The second mounting portion 531 is located above the outer ring air inlet hole 51 and / or at the end opposite to the outer ring air inlet hole 51, so as to reduce the resistance generated by the second mounting portion 531 to the flow of gas, while ensuring the stability and uniformity of the air pressure inside the fire divider 5, thereby further ensuring the uniformity of the outer ring flame.

[0040] Optionally, a second mounting hole 53 is opened on the second mounting portion 531, and the outer fire cover 2 is fixed to the second mounting portion 531 by passing the second screw 6 through the second mounting hole 53, thereby realizing the installation and positioning between the outer fire cover 2 and the fire distribution base 50.

[0041] On the other hand, the present invention provides a burner, including the above-mentioned fire divider 5, and also including an outer fire cover 2 and an inner fire cover 1 installed on the upper side of the fire divider base 50, the outer fire cover 2 is arranged on the outer ring fire divider groove 501, and the inner fire cover 1 is arranged on the inner ring fire divider groove 502.

[0042] Optionally, a plurality of spaced-apart outer ring fire hole groups are provided on the circumference of the outer fire cover 2, and a pot support avoidance area 201 is provided between two adjacent outer ring fire hole groups. The outer ring fire hole group includes a plurality of adjacent outer ring fire holes 20. By providing the pot support avoidance area 201, the outer ring fire holes 20 will not be aligned with the pot support, thereby preventing the pot support from being burned by the outer ring flame. At the same time, the firepower of the outer ring flame can also avoid the pot support, ensuring that the firepower can be concentrated on the cooking pot. The burner provided by the present invention fixes the outer fire cover 2 on the fire distribution base 50 by means of a second screw 6, mainly to control the relative position of the outer fire cover 2 and the fire distribution base 50, and to achieve a fool-proof installation effect, so that the pot support avoidance area 201 is aligned with the pot support.

[0043] In another aspect, the present invention provides a gas stove comprising the burner mentioned above.

[0044] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
