Description

Technical Field

[0001] This utility model relates to the field of stove technology, specifically to an inner ring burner cap and stove. Background Technology

[0002] Existing cooktops generally consist of two burner caps, an inner ring and an outer ring. The inner ring burner cap typically has flame holes and flame stabilizing grooves. The cooktop uses elements such as ignition needles and thermocouples to generate and maintain the flame. Traditionally, to prevent liquid or water from clogging the ignition holes, the inner ring burner cap often features a top cover above the flame holes and anti-clogging grooves on the side of the burner cap body. However, in current designs, the inner ring burner cap is generally less effective at preventing liquid or water from clogging the flame holes, and it can also affect combustion within the inner ring burner cap, such as causing increased smoke levels and thus affecting burner efficiency. Utility Model Content

[0003] To address the technical problems of existing stoves, this utility model provides an inner ring burner cover. The top cover is recessed to form an oil collection groove to collect oil and other impurities. When the oil collection groove is full, the overflowing oil and other impurities can flow into the dripping chamber through the guide ring groove, thereby preventing oil and other impurities from clogging the burner holes.

[0004] The technical solution provided by this utility model is as follows: an inner ring flame cap, including a flame cap body and a top cover; the top cover is disposed on the upper side of the flame cap body, and the middle part of the top cover is recessed towards the side where the flame cap body is located to form an oil collecting groove; there is a gap between the top cover and the flame cap body to form a flow guiding ring groove; a partition wall is fixedly disposed inside the flame cap body, the partition wall encloses a dripping cavity, the dripping cavity is connected to the external environment, and the flow guiding ring groove is connected to the dripping cavity; a flame hole is provided on the flame cap body, and a gas mixing cavity is formed between the flame cap body and the partition wall, and the flame hole is connected to the gas mixing cavity.

[0005] Optionally, the flow guide groove is inclined relative to the horizontal plane, and the height of the flow guide groove near the dripping cavity is lower than the height of the flow guide groove away from the dripping cavity.

[0006] Optionally, the angle A between the centerline of the flow guide groove and the horizontal plane is 10° to 15°.

[0007] Optionally, a flow guide groove is provided at the edge of the top cover.

[0010] Optionally, the angle B between the centerline of the fire hole and the horizontal plane is 50° to 70°.

[0011] A stove, comprising the aforementioned inner ring burner cap.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: In view of the technical problems of defects in existing stoves, the inner ring burner cover proposed by this utility model can collect oil and other impurities through the oil collection groove of the top cover. When the oil collection groove is full, the overflowing oil and other impurities can flow into the dripping cavity through the guide ring groove, thereby avoiding the blockage of the burner holes by oil and other impurities.

[0019] Example 1

[0020] Combined with appendix Figure 1-3 This embodiment proposes an inner ring flame cap, including a flame cap body 1 and a top cap 2.

[0021] The top cover 2 is located on the upper side of the flame cap body 1, and the middle part of the top cover 2 is recessed towards the side where the flame cap body 1 is located to form an oil collection groove 3.

[0022] There is a gap between the top cover 2 and the flame cap body 1 to form a flow guiding ring groove 4. A partition wall 5 is fixedly installed inside the flame cap body 1. The partition wall 5 encloses and forms a dripping cavity 6. The dripping cavity 6 is connected to the external environment. The flow guiding ring groove 4 is connected to the dripping cavity 6.

[0023] The flame cap body 1 is provided with flame holes 7, and the flame cap body 1 and the partition wall 5 form a gas mixing chamber 8, and the flame holes 7 are connected to the gas mixing chamber 8.

[0024] The basic working principle of the inner ring burner in this embodiment is as follows: part of the fuel gas and air are mixed in the mixing chamber 8, and the mixed gas can be ignited as it flows out of the burner hole 7.

[0025] In this embodiment, the inner ring burner cap can also prevent dripping oil and other impurities from clogging the burner holes 7. The principle is that during the cooking process, when oil and other impurities drip onto the top surface of the top cover 2, the middle part of the top cover 2 is recessed towards the burner cap body 1 to form an oil collection groove 3. The oil and other impurities can be collected by the oil collection groove 3 and will not flow randomly, so that the oil cannot drip directly onto the burner cap body 1, thus preventing the oil and other impurities from flowing into the burner holes 7 along the burner cap body 1 and causing the burner holes 7 to be blocked.

[0026] When there is a lot of oil in the oil collection tank 3, the oil will overflow. The overflowing oil will flow through the edge of the top cover 2 to the lower side of the top cover 2, that is, the oil will flow into the guide ring groove 4 and flow into the dripping chamber 6 along the guide ring groove 4. This can completely prevent oil, water droplets and other accumulated impurities from flowing through the top cover 2 and along the burner body 1 into the burner hole 7, causing the burner hole 7 to be blocked.

[0027] Furthermore, since the drip chamber 6 is connected to the external environment, the secondary air required for auxiliary combustion of the inner ring burner can directly reach the root of the burner hole 7 through the drip chamber 6, replenishing the oxygen required by the inner ring burner, thereby reducing flue gas production and improving combustion efficiency.

[0028] The secondary air required for combustion of the inner ring burner to assist in the combustion of the gas refers to the air supplied from other sources besides the primary air around the burner during the combustion process, mainly to ensure more complete combustion of the gas. Secondary air typically enters the combustion zone through gaps around the burner or specially designed channels; in this embodiment, the dripping chamber 6 serves as a passage for the secondary air.

[0029] In a further embodiment, the guide ring groove 4 is inclined relative to the horizontal plane, and the height of the side of the guide ring groove 4 near the dripping chamber 6 is lower than the height of the side away from the dripping chamber 6. This allows impurities such as oil to flow from a higher to a lower position along the guide ring groove 4, thereby better guiding the flow of oil and other impurities and better preventing them from clogging the flame hole 7.

[0030] In a preferred embodiment, the angle A between the centerline of the flow guide groove 4 and the horizontal plane is 10° to 15°. This angle setting can prevent the flow guide groove 4 from being too steep, thus avoiding excessive occupation of height space, while ensuring the flow guiding effect of impurities such as oil.

[0031] In another embodiment, a guide groove 9 is provided at the edge of the top cover 2. The guide groove 9 provides a flow path for impurities such as oil, which helps to control the overflow process of impurities such as oil and achieves a better guiding effect, ensuring that the oil can flow smoothly into the guide ring groove 4.

[0032] In other embodiments, the depth h of the oil collection trough 3 is 6% to 8% of the diameter D of the top cover 2. This embodiment further designs the degree of concavity of the oil collection trough 3. This degree of concavity can ensure the collection of some oil and other impurities, while ensuring that the oil collection trough 3 is not too concave and encroaches on the layout space of the mixing chamber 8 and other structures. It can also avoid the problem of the oil inside the oil collection trough 3 being difficult to clean due to being too deep.

[0033] In this embodiment, the burner hole 7 should be inclined, with the height of the end of the burner hole 7 near the mixing chamber 8 lower than the height of the end away from the mixing chamber (8). More preferably, the angle B between the centerline of the burner hole 7 and the horizontal plane should be controlled between 50° and 70°. This ensures that the gas flowing from the mixing chamber 8 out of the burner hole 7 is ejected upwards, thereby helping to ensure the combustion effect of the burner.

[0034] In summary, in response to the technical problems of existing stoves, this utility model proposes an inner ring burner cover that can collect oil and other impurities through the oil collection groove 3 of the top cover 2. The overflowing oil and other impurities collected in the oil collection groove 3 can then flow into the dripping chamber 6 through the guide ring groove 4, thereby preventing oil and other impurities from clogging the burner holes 7.

[0035] In addition, the drip chamber 6, which is connected to the external environment, can allow secondary air to directly reach the root of the fire hole 7 in the burner body 1, replenishing the required secondary air, so that the gas can be fully burned, reducing flue gas and thus improving the combustion efficiency of the burner.
