Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, and in particular to a gas-blocking speed-increasing flame distributor and a gas stove. Background Technology

[0002] Integrated cooktops and gas cooktops are common kitchen appliances used in households, and the burner is an important component of integrated cooktops and gas cooktops.

[0003] According to existing technology, there is a burner distributor seat, with the publication number CN218626831U, which includes a burner cap base, an inner ring of the base, and a base. The inner ring of the base and the base are connected by several gas supply pipes arranged at equal angles. The gas supply pipes are set obliquely upwards and form a gas supply channel inside. An inner burner cap is covered on the inner ring of the base. The inner burner cap has a central burner hole. Several inner and outer burner holes are arranged on the outer sides of the inner and outer burner caps, respectively. The base has thermocouple holes and igniter holes. The upper end face of the outer burner cap corresponding to the igniter hole has an ignition groove. The outer burner cap is covered on the base to form an outer flame distribution chamber. The outer flame distribution chamber is an annular gas chamber. However, due to the low gas pressure, slow flow rate, and short flame in the outer flame distribution chamber, the thermal efficiency is low. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a gas-burning speed-increasing flame distributor and gas stove with fast flow rate and long flame, resulting in high thermal efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is: a flame spreader, comprising a flame cap and a base, wherein the flame cap and the base are joined together to form an annular cavity, and the flame cap is provided with a flame outlet hole; it further comprises:

[0006] A suffocating structure is used to reduce the volume of the annular cavity. The suffocating structure is located in the annular cavity, and the space between the annular cavity and the suffocating structure forms a suffocating chamber. The suffocating chamber is connected to the flame outlet.

[0007] With the above structure, this utility model has the following advantages compared with the prior art: by setting an air-blocking structure in the annular cavity, the volume of the annular cavity is reduced by the air-blocking structure, which increases the air pressure in the annular cavity, increases the flow rate, and lengthens the flame, thereby resulting in high thermal efficiency.

[0008] Preferably, the air-holding structure is a ring structure, with the center of the ring structure located in the inner ring of the ring cavity. Setting the air-holding structure as a ring structure can minimize the volume inside the ring cavity, thereby increasing the air pressure and greatly improving the thermal efficiency.

[0009] Preferably, the annular structure is located near the outer ring, center, or inner ring of the annular cavity, and the position of the annular structure is selected according to the position of the flame outlet.

[0010] Preferably, the air-holding structure and the annular cavity are integrated as a whole.

[0011] Preferably, the air-holding structure is detachably connected to the annular cavity.

[0012] Preferably, the air-blocking structure is located on the flame cap or base.

[0013] Preferably, when the air-holding structure and the annular cavity are integrated, the annular structure has an expansion channel, which is integrated with the air outlet channel on the flame cap. The annular structure has an air inlet, and the annular cavity is connected to the expansion channel through the air inlet. The expansion channel inside the air-holding structure increases the width of the air outlet channel, making it less likely for the flame from the flame outlet to backfire through the air outlet channel, thus preventing backfire.

[0014] Preferably, when the air-holding structure is detachably connected to the annular cavity, the flame outlet is located on the side of the flame cap and the side of the flame outlet is a first inclined surface, and the position of the annular structure corresponding to the flame outlet is a second inclined surface. The first inclined surface and the second inclined surface are parallel to each other, which makes the width of the air-holding cavity narrower, the pressure greater, the flow rate faster, and greatly improves the thermal efficiency.

[0015] Preferably, the venting structure is made of metal. The venting structure can absorb heat, and when the burner is turned off, the heat on the venting structure can continue to heat the pot, resulting in quick boiling and energy saving.

[0016] Preferably, the flame outlet is located on the upper surface of the fire cap, directly facing the bottom of the pot, allowing the pot to continue heating directly through the flame outlet, resulting in high thermal efficiency.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Figure 1 This is a front sectional view of a flame-increasing and pressure-reducing distributor according to this utility model. The distributor includes a flame cap 1 and a base 2. The flame cap 1 is positioned above the base 2. The outer surface of the flame cap 1 has a flame outlet hole 110, and the interior of the flame cap 1 has a gas outlet channel 120 communicating with the flame outlet hole 110. The flame cap 1 and the base 2 are joined together to form an annular cavity 3. The base 2 has a gas supply channel 210, which communicates with the annular cavity 3. The annular cavity 3 is connected to the flame outlet hole 110 via the gas outlet channel 120. A gas supply pipe is connected to the gas supply channel 210. Gas in the gas supply pipe passes sequentially through the gas supply channel 210, the annular cavity 3, and the gas outlet channel 120, and is ejected from the flame outlet hole 110. The gas supply pipe is generally located at the center of the base 2.

[0028] To reduce the volume within the annular cavity, it also includes a gas-trapping structure 4, which is located within the annular cavity 3. Since the gas-trapping structure 4 has a certain volume, it occupies a certain space within the annular cavity 3. Thus, the space within the annular cavity 3 excluding the space occupied by the gas-trapping structure 4 is the gas-trapping chamber 5. The gas-trapping chamber 5 has a smaller volume than the existing annular cavity 3, and therefore holds less gas. The gas forms trapped gas within the gas-trapping chamber 5, which increases the gas pressure, increases the flow rate, and lengthens the flame, resulting in higher thermal efficiency for heating the bottom of the pot.

[0029] The flame cap 1 can be an outer ring flame cap, an inner ring flame cap, or a middle ring flame cap; there are no restrictions here.

[0030] Figure 2This is a perspective view of the gas-blocking structure of a gas-blocking speed-increasing flame distributor according to this utility model. The gas-blocking structure 4 is a ring structure, and the center of the ring structure is located within the inner ring of the ring cavity 3. The ring structure can minimize the volume of the ring cavity 3, that is, minimize the volume of the gas-blocking chamber 5. In addition, since the center of the ring structure is located within the inner ring of the ring cavity 3, and the center of the ring structure is also located within the center of the inner ring of the ring cavity 3, the gas-blocking chamber 5 is also ring-shaped, ensuring uniform pressure and stable flame throughout the gas-blocking chamber 5. The gas-blocking structure 4 can also be a block structure, a polygonal structure, an irregular shape, etc., as long as it has a certain volume.

[0031] Figure 3 This is a perspective view of the gas-blocking structure and base of a gas-blocking speed-increasing flame divider according to this utility model. The annular gas-blocking structure 4 is located near the inner ring of the annular cavity 3, or near the outer ring of the annular cavity 3, or near the center of the annular cavity 3. Specifically, it is selected according to the position of the flame outlet 110. For example, when the flame outlet 110 is located on the outer side of the flame cap 1, that is, the outer flame, the gas-blocking structure 4 is located near the outer ring of the annular cavity 3; when the flame outlet 110 is located on the inner side of the flame cap 1, that is, the inner flame, the gas-blocking structure 4 is located near the inner ring of the annular cavity 3; when the flame outlet 110 is located on both the outer and inner sides of the flame cap 1, that is, the inner and outer flames, the gas-blocking structure 4 is located near the center of the annular cavity 3.

[0032] Specifically, to ensure that the gas-blocking chamber 5 is connected to the gas supply channel 210 and the gas outlet channel 120, that is, to prevent the gas-blocking structure 4 from blocking the gas flow from the gas-blocking chamber 5 into the gas outlet channel 120, and also to prevent the gas-blocking structure 4 from blocking the gas flow from the gas supply channel 210 into the gas-blocking chamber 5, the following methods are adopted: 1. A venting groove 430 is provided on the bottom surface of the gas-blocking structure 4; 2. The venting groove 430 runs through the left and right sides of the gas-blocking structure 4, and the venting groove 430 can also be provided on the upper surface of the gas-blocking structure 4; 3. A gap can also be provided between the upper surface of the gas-blocking structure 4 and the top surface of the gas-blocking chamber 5; 4. This gap can also be located between the bottom surface of the gas-blocking structure 4 and the bottom surface of the gas-blocking chamber 5. At least one of the following methods is sufficient:

[0033] Specifically, the air-blocking structure 4 can be installed on either the flame cap 1 or the base 2. The air-blocking structure 4 can be integrated with the annular cavity 3 as a whole, or it can be detachably connected to the annular cavity 3.

[0034] Figure 4This is a perspective view of a blazing-increasing flame spreader base according to this utility model. When the blazing structure 4 is detachably connected to the annular cavity 3, that is, when the blazing structure 4 is detachably connected to the flame cap 1 and the base 2, the base 2 is provided with a support column 220 corresponding to the position of the annular cavity 3. The blazing structure 4 is provided with a connecting through hole 420. The flame cap 1 is provided with a mounting column 130 corresponding to the position of the annular cavity 3. Bolts are sequentially passed through the support column 220 and the connecting through hole 420 and screwed into the mounting column 130. Figure 5 This is a perspective view of the flame cap of a flame-increasing, pressure-reducing distributor according to this utility model. Specifically, the flame outlet 110 is located on the side of the flame cap 1, and the side with the flame outlet 110 is a first inclined surface. The annular structure corresponding to the position of the flame outlet 110 is a second inclined surface. The first and second inclined surfaces are parallel to each other, which narrows the width of the pressure-reducing chamber 5, increases the pressure, and increases the flow rate, greatly improving the thermal efficiency. The diameter of the first inclined surface decreases from the center away from the center of the flame cap 1 to the diameter closer to the center away from the center of the flame cap 1. Specifically, in order to connect the annular cavity 3 with the air outlet channel 120, the annular cavity 3 is provided with multiple air inlets 310.

[0035] Figure 6 This is a front sectional view of the flame cap and the gas-blocking structure of a gas-blocking speed-increasing flame distributor according to this utility model. When the gas-blocking structure 4 and the annular cavity 3 are integrated, the gas-blocking structure 4 and the inner wall of the flame cap 1 are integrated, that is, the gas-blocking structure 4 and the outer ring of the annular cavity 3 are integrated. An expansion channel 410 is provided inside the annular structure. The expansion channel 410 and the gas outlet channel 120 on the flame cap 1 are integrated. An air inlet 310 is provided on the annular structure. The annular cavity 3 is connected to the expansion channel 410 through the air inlet 310. The expansion channel 410 inside the gas-blocking structure 4 increases the width of the gas outlet channel 120, so that the flame of the flame outlet 110 is less likely to backfire through the gas outlet channel 120, and thus no backfire will occur. Specifically, the expansion channel 410 is an annular channel. The expansion channel 410 and the gas outlet channel 120 have the same structure, both being annular channels. That is to say, the expansion channel 410 is an extension of the gas outlet channel 120.

[0036] Figure 7 This is a perspective view of a flame spreader with increased power output according to this utility model. The flame cap 1 is located above the base 2, and the flame outlet 110 is located on the outer side of the flame cap 1. The flame outlet 110 can also be located on the upper surface or the inner side of the flame cap 1, and the position of the flame outlet 110 is not limited. The shape of the flame outlet 110 can also be circular, annular, arc-shaped, etc., and the shape of the flame outlet 110 is not limited.

[0037] A gas stove comprising a gas-blocking speed-increasing flame distributor as described in any of the preceding claims, and a base 2 for mounting on the gas stove.

[0038] Specifically, the principle of this invention is to install an air-blocking structure 4 inside the annular cavity 3, thereby reducing the volume inside the annular cavity 3. This increases the air pressure inside the annular cavity 3, increases the flow rate, and lengthens the flame, resulting in higher thermal efficiency.

[0039] Action process: Figure 1 For example, the gas in the gas pipeline enters the gas-blocking chamber 5 through the gas supply channel 210, the gas pressure increases, the flow rate accelerates, and it enters the gas outlet channel 120 and is finally ejected from the flame outlet 110. The flame ejected from the flame outlet 110 is long, thus resulting in high thermal efficiency.

[0040] Based on the above solutions, if any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
