Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to an outer ring fire cover, a burner and a gas stove. Background Art

[0002] At present, household gas stoves generally have a burner, which usually includes an outer ring fire cover and a central fire cover. The outer ring fire cover is arranged around the outer periphery of the central fire cover. Fire holes are usually arranged on the outer wall of the outer ring fire cover and the outer wall of the central fire cover, and the mixed gas of gas and air flows out from the fire holes of the outer ring fire cover and the fire holes of the central fire cover and burns. In the existing outer ring fire cover, since the radius of the outer wall of the outer ring fire cover is small and the fire holes are arranged on the outer wall, the radius of the fire hole circle where the fire holes are located is small, during the cooking process, the liquid overflowing from the pot will drip onto the cover body of the outer ring fire cover and flow down along the cover body to the root of the burner, causing the burner to go out of flame or ignite poorly. Utility Model Content

[0003] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, an outer ring fire cover is provided, and the technical solution is as follows.

[0004] The outer ring fire cover of the utility model comprises a fire cover body, which comprises an inner wall, an outer wall and a connecting wall, wherein the inner wall, the connecting wall and the outer wall enclose a gas channel, the connecting wall comprises a first section, a second section and a third section, the first section is connected to the inner wall, the third section is connected to the outer wall, the second section is connected between the first section and the third section, the second section is provided with a fire outlet hole connecting the gas channel with the outside, and the third section is provided below the second section.

[0005] The outer ring fire cover of the utility model is arranged by a three-section connecting wall, and a fire hole is arranged on the second section, and a third section is provided outside the fire hole circle where the fire hole is located. Compared with the outer ring fire cover, the radius is increased, and the fire hole is also arranged on the outer side wall. The radius of the fire circle where the fire hole is located in the utility model will not be too large, thereby avoiding the phenomenon of burning the handle of the pot or the kitchen utensils placed around the gas stove during the cooking process; the third section is respectively connected to the second section and the outer side wall, and by setting the third section lower than the second section, in this way, during the cooking process, when liquid overflowing from the pot drips onto the fire cover body, the liquid can flow outward along the third section until it flows out of the outer ring of the outer ring fire cover, thereby avoiding the liquid flowing along the fire cover body to the root of the burner with the outer ring fire cover, causing the burner to go out or ignite poorly, and it is convenient for users to clean the overflowed liquid.

[0006] Exemplarily, the third section is parallel to the installation plane, and the installation plane is the plane where the bottom of the outer side wall is located. In this way, when the outer ring fire cover is installed on the fire distributor seat of the burner, a gas mixing space can be formed between the third section, the outer side wall and the fire distributor seat, and the mixture of gas and air can form a cyclone when entering the gas mixing space, so that the gas and air can be fully mixed, thereby making the gas burn more fully.

[0007] Exemplarily, the third section has a length D, and the length D is 7 mm to 20 mm. The length D of the third section within this range can form a gas mixing space with this length range between the third section, the outer wall and the fire-distributing seat, so that the gas-air mixture entering the gas mixing space can form a cyclone, so that the gas and air can be mixed more fully, and then the gas can burn more fully.

[0008] Exemplarily, the third section is tilted relative to the installation plane, and the installation plane is the plane where the bottom of the outer side wall is located. With such a configuration, on the one hand, the third section can guide the liquid overflowing from the pot, so that the liquid can flow out of the outer ring of the outer ring fire cover. In this way, it can not only prevent the liquid from flowing to the root of the burner, causing problems such as flameout or poor ignition of the burner, but also prevent the liquid from being retained on the third section, making it difficult for the user to clean the outer ring fire cover; on the other hand, when the outer ring fire cover is installed on the fire-distributing seat of the burner, a gas-mixing space can be formed between the third section, the outer side wall and the fire-distributing seat, and a cyclone can be formed when the mixture of gas and air enters the gas-mixing space. The tilted setting of the third section can increase the gas-mixing space, thereby increasing the cyclone formed by the mixture of gas and air, so that the gas and air can be mixed more fully, thereby making the gas burn more fully.

[0009] Exemplarily, the orthographic projection of the third section on the installation plane has a length D, and the length D is 7 mm to 20 mm. The orthographic projection length D of the third section within this range can form a gas mixing space with this length range between the third section, the outer side wall and the fire-distributing seat, so that the gas-air mixture entering the gas mixing space can form a cyclone, so that the gas and air can be fully mixed, and then the gas can burn more fully.

[0010] Exemplarily, the third section forms an angle α with the installation plane, and the angle α is 10° to 30°. With such a configuration, on the one hand, the angle α is within this range, which can ensure that the third section has a guiding effect on the liquid overflowing from the pot, thereby preventing the liquid from flowing to the root of the burner, causing problems such as flameout or poor ignition of the burner, and preventing the liquid from being retained on the third section, making it difficult for the user to clean the outer ring fire cover; on the other hand, the angle α formed between the third section and the installation plane increases the gas mixing space, thereby increasing the cyclone formed by the mixture of gas and air, so that the gas and air can be mixed more fully, thereby making the gas burn more fully.

[0011] Exemplarily, an angle β is formed between the second section and the mounting plane, and the angle β is 60° to 80°, and the mounting plane is the plane where the bottom of the outer wall is located. When the angle β is within this range, it is convenient to process the fire hole on the second section during production, and when in use, the flame burning at each fire hole can heat the pot well.

[0012] Exemplarily, the first section extends obliquely upward from the top of the inner side wall. With such arrangement, when cooking, the liquid overflowing from the pot can be guided to the inner side wall by the first section, preventing the liquid from flowing into the fire outlet hole of the second section and blocking the fire outlet hole. When producing the burner, the outer ring fire cover needs to be assembled on the fire distributor seat. Since the first section extends obliquely upward from the top of the inner side wall, the height of the side wall of the fire distributor seat and the outer ring fire cover can be shortened, reducing material consumption and reducing costs.

[0013] For example, an angle Y is formed between the first section and the installation plane, and the angle Y is 10° to 30°, and the installation plane is the plane where the bottom of the outer wall is located. When the angle Y is within this range, it can be ensured that the first section has a guiding effect on the liquid overflowing from the pot, so that the liquid overflowing from the pot can be guided to the inner wall by the first section, thereby preventing the liquid from flowing into the fire outlet hole of the second section, so that the fire outlet hole is blocked.

[0014] According to another aspect of the utility model, a burner is provided, which includes a fire distribution seat and the outer ring fire cover as described above, and the outer ring fire cover is arranged on the fire distribution seat. The burner of the utility model includes the outer ring fire cover as described above, and since the outer ring fire cover has the beneficial effects as described above, the burner including the outer ring fire cover as described above must also have the beneficial effects as described above.

[0015] According to another aspect of the utility model, a gas stove is provided, which includes a stove bottom shell and the burner as described above, and the burner is arranged on the stove bottom shell. The gas stove of the utility model includes the outer ring fire cover as described above. Since the burner as described above has the beneficial effects as described above, the gas stove including the burner as described above must also have the beneficial effects as described above.

[0016] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

The first section 131 may be connected to the inner side wall 110, the third section 133 may be connected to the outer side wall 120, and the second section 132 may be connected between the first section 131 and the third section 133. The second section 132 may be provided with a fire hole 1321 connecting the gas channel 140 with the outside. There may be a plurality of fire holes 1321, and the plurality of fire holes 1321 may be arranged at intervals along the circumference of the second section 132, and every two fire holes 1321 may be arranged alternately. The third section 133 may be arranged lower than the second section 132. The third section 133 may have a first end 1331 and a second end 1332, the first end 1331 may be connected to the second section 132, and the second end 1332 may be connected to the outer side wall 120. Along the central axis direction, the plane where the second section 132 and the first section 131 are connected may be higher than the plane where the first end 1331 is located and the plane where the second end 1332 is located.

[0036] The outer ring fire cover 10 of the utility model is provided by a three-section connecting wall 130, and a fire hole 1321 is provided on the second section 132, and a third section 133 is provided outside the fire hole circle where the fire hole 1321 is located. Compared with the case where the radius of the outer ring fire cover is increased and the fire hole is also provided on the outer side wall, the radius of the fire circle where the fire hole 1321 is located in the utility model will not be too large, thereby avoiding the phenomenon of burning the handle of the pot or the kitchen utensils placed around the gas stove during the cooking process; the third section 133 is respectively It is connected to the second section 132 and the outer wall 120, and by setting the third section 133 lower than the second section 132, during the cooking process, when liquid overflowing from the pot drips onto the fire cover body 100, the liquid can flow outward along the third section 133 until it flows out of the outer circle of the outer ring fire cover 10, thereby preventing the liquid from flowing along the fire cover body 100 to the root of the burner with the outer ring fire cover 10, causing the burner to go out of flame or have poor ignition, and making it convenient for users to clean the overflowed liquid.

[0037] In the embodiments of the present utility model, in combination with reference to Figures 1 to 5, the third section 133 can be parallel to the installation plane. The installation plane can be the plane where the bottom of the outer side wall 120 is located, that is, the installation plane can be the plane where the end of the outer side wall 120 away from the third section 133 is located. When the outer ring fire cover 10 is in use (that is, when installed on the fire distribution seat 20 of the burner), the installation plane can be a horizontal plane. In this way, when the outer ring fire cover 10 is installed on the fire distribution seat 20 of the burner, a gas mixing space 30 can be formed between the third section 133, the outer side wall 120 and the fire distribution seat 20, and the mixture of gas and air entering the gas mixing space 30 can form a cyclone, so that the gas and air can be fully mixed, thereby making the gas burn more fully.

[0038] In the embodiments of the present invention, refer to Figure 3 The third section 133 may have a length D, and the length D may be 7 mm to 20 mm. For example, the length D may be 7 mm, 13 mm, 20 mm, etc. The length D of the third section 133 within this range may form a gas mixing space 30 with this length range between the third section 133, the outer wall 120, and the flame distributor 20, so that the gas mixture of gas and air entering the gas mixing space 30 may form a cyclone, so that the gas and air may be mixed more fully, and the gas may burn more fully.

[0039] In the embodiments of the present utility model, in combination with reference to Figures 6 to 10 , the third section 133 can be inclined relative to the installation plane. The installation plane can be the plane where the bottom of the outer side wall 120 is located, that is, the installation plane can be the plane where the end of the outer side wall 120 away from the third section 133 is located. When the outer ring fire cover 10 is in use (that is, when installed on the flame distributor 20 of the burner), the installation plane can be a horizontal plane. With such an arrangement, on the one hand, the third section 133 can guide the liquid overflowing from the pot, so that the liquid can flow out of the outer ring of the outer ring fire cover 10. In this way, not only can the liquid be prevented from flowing to the root of the burner, causing problems such as flameout or poor ignition of the burner, but also the liquid can be prevented from being retained on the third section 133, causing difficulty for the user to clean the outer ring fire cover 10; on the other hand, when the outer ring fire cover 10 is installed on the fire distributor seat 20 of the burner, a mixing space 30 can be formed between the third section 133, the outer wall 120 and the fire distributor seat 20, and a cyclone can be formed when the mixture of gas and air enters the mixing space 30. The inclined setting of the third section 133 can increase the mixing space 30, thereby increasing the cyclone formed by the mixture of gas and air, so that the gas and air can be mixed more fully, thereby making the gas burn more fully.

[0040] In the embodiments of the present invention, refer to Figure 8The orthographic projection of the third section 133 on the installation plane may have a length D, and the length D may be 7 mm to 20 mm. For example, the length D may be 7 mm, 13 mm, 20 mm, etc. The orthographic projection length D of the third section 133 within this range may form a gas mixing space 30 with this length range between the third section 133, the outer side wall 120, and the flame distributor 20, so that the gas mixture of gas and air entering the gas mixing space 30 may form a cyclone, so that the gas and air may be fully mixed, and the gas may burn more fully.

[0041] In the embodiment of the present utility model, refer again to Figure 8 , an angle α can be formed between the third section 133 and the installation plane, and the angle α can be 10° to 30°. For example, the angle α can be 10°, 20°, 30°, and so on. On the one hand, within this range, the angle α can ensure that the third section 133 has a guiding effect on the liquid overflowing from the pot, thereby preventing the liquid from flowing to the root of the burner, causing problems such as flameout or poor ignition of the burner, and preventing the liquid from being retained on the third section 133, making it difficult for the user to clean the outer ring fire cover 10; on the other hand, the angle α formed between the third section 133 and the installation plane increases the gas mixing space 30, thereby increasing the cyclone formed by the mixture of gas and air, so that the gas and air can be mixed more fully, thereby making the gas burn more fully.

[0042] In the embodiments of the present invention, refer to Figure 5 , an angle β may be formed between the second section 132 and the installation plane, and the angle β may be 60° to 80°. For example, the angle β may be 60°, 70°, 80°, and so on. The installation plane may be the plane where the bottom of the outer wall 120 is located, that is, the installation plane may be the plane where the end of the outer wall 120 away from the third section 133 is located. The installation plane may be a horizontal plane. With such a configuration, the angle β is within this range, and during manufacturing, it is convenient to process the fire holes 1321 on the second section 132, and during use, the flame burning at each fire hole 1321 can heat the cookware well.

[0043] In the embodiments of the present utility model, in combination with reference to Figure 3 and Figure 4 , the first section 131 can extend obliquely upward from the top of the inner side wall 110. With such a configuration, when cooking, the liquid overflowing from the pot can be guided to the inner side wall 110 by the first section 131, so as to prevent the liquid from flowing into the fire outlet hole 1321 of the second section 132, thereby blocking the fire outlet hole 1321. When producing the burner, the outer ring fire cover 10 needs to be assembled onto the fire distributor seat 20. Since the first section 131 extends obliquely upward from the top of the inner side wall 110, the height of the side wall of the fire distributor seat 20 and the outer ring fire cover 10 can be shortened, thereby reducing the loss of materials and the cost.

[0044] In the embodiments of the present invention, refer to Fig. 9 , an angle Y may be formed between the first section 131 and the installation plane, and the angle Y may be 10° to 30°. For example, the angle Y may be 10°, 20°, 30°, and so on. Similarly, the installation plane may be the plane where the bottom of the outer wall 120 is located, that is, the installation plane may be the plane where the end of the outer wall 120 away from the third section 133 is located. When the outer ring fire cover 10 is in use (that is, when installed on the fire distribution seat 20 of the burner), the installation plane may be a horizontal plane. Within this range of the angle Y, it can be ensured that the first section 131 has a guiding effect on the liquid overflowing from the pot, so that the liquid overflowing from the pot can be guided to the inner wall 110 by the first section 131, thereby preventing the liquid from flowing into the fire outlet 1321 of the second section 132, so that the fire outlet 1321 is blocked.
