Referring to fig. 3 and 5, the distributor 3 is disposed above the base 1, and a gap is formed between the distributor 3 and the base 1, and the distributor 3 is located above the cooking bench 2. At this time, the distributor 3 may be a portion of the burner located outside the installation hole 22 of the hob 2, and the portion of the burner located outside the installation hole 22 of the hob 2 may further include a fire cover 6, where the fire cover 6 is disposed on the distributor 3, so that the distributor 3 provides sufficient fuel gas for the fire hole 61 on the fire cover 6 to burn.

With continued reference to fig. 5, the distributor 3 includes a distributor body 31 and an injection pipe 32, the injection pipe 32 is disposed at the bottom of the distributor body 31, an inlet of the injection pipe 32 is disposed opposite to an outlet of the nozzle 4, and the injection pipe 32 is used for injecting air and fuel gas. The fuel gas here refers to high-speed fuel gas injected into the nozzle 4, and the air refers to air existing in the gap between the base 1 and the distributor 3, and is injected into the injection pipe 32 as the fuel gas is injected into the injection pipe 32 at a high speed.

Referring to fig. 3 and 5, a channel (not shown) for delivering fuel gas should be disposed in the distributor body 31, and the channel can be used for mixing the fuel gas and air ejected from the ejector tube 32, and the channel is connected to the ejector tube 32 and the fire hole 61 on the fire cover 6, so that the fuel gas and primary air ejected from the ejector tube 32 are supplied to the fire hole 61 and ignited.

Referring to fig. 4 and 5 in combination, the number of ejector tubes 32 should also be the same as the number of nozzles 4 such that each nozzle 4 is opposite only one ejector tube 32. The relative direction of the jet flow of the nozzle 4 may be the same as the direction of the opening of the ejector tube 32 (which may be understood as the direction of the axis of the ejector tube 32 near the nozzle 4), or may be a small included angle, for example, an included angle within 15 degrees, between the jet flow direction of the nozzle 4 and the direction of the opening of the ejector tube 32, and when the ejector tube 32 contacts the nozzle 4 or only has a distance not exceeding the diameter of the nozzle 4, the injected fuel gas of the nozzle 4 may enter the ejector tube 32.

Referring to fig. 3, 4 and 5, the guide assembly 5 is disposed between the base 1 and the distributor 3, the guide assembly 5 includes a protrusion 51 and a recess 52, the protrusion 51 is slidably disposed in the recess 52, one of the protrusion 51 and the recess 52 is disposed on the top surface of the base 1, and the other of the protrusion 51 and the recess 52 is disposed on the distributor body 31; wherein the recess 52 extends in the direction of distribution of the nozzle 4 and the ejector tube 32.

Referring to fig. 4 and 5, the protruding portion 51 and the recessed portion 52 should have a height and a depth along a direction perpendicular to the top surface of the cooking bench 2, and the distribution direction of the nozzle 4 and the injection pipe 32 may be parallel to the top surface of the cooking bench 2, so that the protruding portion 51 and the recessed portion 52 may slide along the distribution direction of the nozzle 4 and the injection pipe 32.

The structure that is provided with between base 1 and distributor 3 in this application and connects through guiding component 5, in this structure bulge 51 slip stretches into in the depressed part 52, and the depressed part 52 extends along the direction of distribution of nozzle 4 and injection pipe 32, makes base 1 and distributor 3 only can take place relative slip along the direction of spraying of nozzle 4. This scheme can avoid taking place the skew in other directions beyond the injection direction of nozzle 4 between base 1 and the distributor 3, avoids the injection direction of nozzle 4 with the injection pipe 32 direction of injection pipe 32 takes place the skew and leads to the gas to reveal, reduces the gas leakage risk that the cooking utensils brought when using.

In some examples, the nozzles 4 and the injection pipes 32 are distributed in a direction parallel to the floor of the cooktop 2, and a gap is provided between the nozzles 4 and the injection pipes 32 to facilitate injection of air; while the protruding portion 51 and the recessed portion 52 can slide in this direction. At this time, even if a certain sliding is generated between the base 1 and the distributor 3, so that the nozzle 4 and the injection pipe 32 are not installed according to the expected position, the jet direction of the nozzle 4 still faces the injection pipe 32, so that the injection pipe 32 can inject the expected amount of fuel gas as well, and the danger of leakage of a large amount of fuel gas is avoided.

In other examples, the distribution direction of the nozzle 4 and the injection pipe 32 may also form an angle with the top surface of the cooking bench 2, for example, 5 °, and the extension direction of the recess 52 may still be the projection direction of the plane where the top surface of the cooking bench 2 is located along the distribution direction of the nozzle 4 and the injection pipe 32. At this time, when the base 1 and the distributor 3 are relatively displaced, the jet direction and the injection direction of the nozzle 4 and the injection pipe 32 are relatively shifted, but when the space between the injection pipe 32 and the nozzle 4 is not beyond the two nozzles 4, the injection pipe 32 can also inject expected fuel gas, so that the danger caused by fuel gas leakage is reduced.

Namely, two degrees of freedom in the sliding direction are provided between the protruding portion 51 and the recessed portion 52, one is the degree of freedom in the direction that the distributor 3 is far away from the base 1 in the height direction, and the other is the degree of freedom in the direction that the distributor 3 is far away from the base 1 in the horizontal direction, so that the limiting effect on the relative movement between the distributor 3 and the base 1 in other directions can be achieved.

In the above example, there is a relatively movable degree of freedom fit between the base 1 and the distributor 3, i.e. the base 1 and the distributor 3 are more easily assembled and disassembled. At the same time, in the two degrees of freedom, the movement can be avoided through the dead weight of the distributor 3 and the friction between the distributor 3 and the base 1, so that the base 1 and the distributor 3 are connected stably in use of the kitchen range.

In some examples, the protrusion 51 may be provided as a bump and the recess 52 may be provided as a groove, such that the bump protrudes into the groove, enabling a connection between the base 1 and the distributor 3.

The shape of the air outlet of the nozzle 4 can be one of a circle and a polygon, and the nozzle 4 can spray fuel gas.

Referring to fig. 9, in other examples, a clearance groove 511 may be formed at the bottom of the protruding portion 51, a gas pipe 41 is further connected between the nozzle 4 and the base 1, the nozzle 4 is connected to one end of the gas pipe 41, the gas pipe 41 and the nozzle 4 are both disposed in the clearance groove 511, and the nozzle 4 is fixedly connected to the protruding portion 51. At this time, the gas outlet of the nozzle 4 may be directed toward the injection pipe 32, and the fuel gas may be injected from the nozzle 4.

Referring to fig. 10, on this basis, the height of the protruding portion 51 is greater than the depth of the recessed portion 52 in a direction perpendicular to the top surface of the hob 2.

With continued reference to fig. 10, when the height of the protruding portion 51 is greater than the depth of the recessed portion 52, the base 1 and the distributor 3 are supported by abutting the top surface of the protruding portion 51 against the deepest surface of the recessed portion 52, so that the above-mentioned gap (shown at a in fig. 10) is formed between the base 1 and the distributor 3, and the ejector tube 32 in the burner is facilitated to introduce air from the gap.

Referring to FIG. 11, in some examples, in a cross-sectional view of the spacing assembly 7 perpendicular to the distribution of the nozzle 4 and the eductor tube 32, the projections 51 and recesses 52 should be a clearance fit to facilitate installation between the projections 51 and recesses 52.

With continued reference to fig. 11, in the above example, the shape of the protruding portion 51 may be square, the shape of the recessed portion 52 may be square, and a gap with a double side smaller than 1mm is provided between the recessed portion 52 and the protruding portion 51, so as to facilitate the installation between the protruding portion 51 and the recessed portion 52. Meanwhile, at least one of the protruding portion 51 and the recessed portion 52 may be further provided with a pressure reducing groove, i.e., an arc-shaped or square groove is formed along a direction perpendicular to the distribution direction of the nozzle 4 and the injection pipe 32, so as to further reduce the installation friction between the protruding portion 51 and the recessed portion 52.

Referring to fig. 12, in other examples, the cross-sectional shape of the protruding portion 51 may be a semicircle, and the cross-sectional shape of the recessed portion 52 may be a semicircle that mates with the protruding portion 51, so that the cambered surface of the protruding portion 51 abuts against the cambered surface of the recessed portion 52, and the supporting function is achieved.

In some examples, the top surface of the protruding portion 51 and the bottom surface of the recessed portion 52 may be configured to be planar, so that the base 1 makes the positional relationship of the two more stable and the supporting relationship more stable by the planar support when the dispenser 3 is supported.

In the above example, the side surface of the protruding portion 51 may be one of a plane and an arc surface, and when the side surface of the protruding portion 51 is a plane, the side surface may be parallel to or form an included angle with the vertical direction of the surface of the cooking bench 2, and the base 1 may support the distributor 3 more stably no matter which scheme is adopted.

Referring to fig. 13, on this basis, the guiding assemblies 5 are provided with a plurality of groups, and the groups of guiding assemblies 5 are distributed at intervals.

When the plurality of groups of guide assemblies 5 are spaced between the base 1 and the distributor 3, and the height of the protruding part 51 in the wire assembly is greater than the depth of the distributor 3, the base 1 can have a more stable supporting effect on the distributor 3.

In this case, the two sets of guide assemblies 5 may be spaced apart by a large distance so that the distributor 3 is supported more stably when being connected to the base 1 through the guide assemblies 5.

In other examples, the guide assemblies 5 may be distributed on the base 1 at any interval, and may also have a similar supporting effect.

In other examples, the guide assemblies 5 may be arranged in other numbers, for example, three sets, four sets or five sets, and the extending directions of the groove portions in all the guide assemblies 5 need only be consistent, so that the above-mentioned supporting effect between the base 1 and the distributor 3 by the guide assemblies 5 can be achieved.

In some examples, when the extending directions of the groove portions in all the guide assemblies 5 are identical, sliding between the base 1 and the distributor 3 in the extending directions of the groove portions can occur, and the sliding distance can be determined by the distance between the nozzle 4 and the ejector tube 32 adjacent to the nozzle on the different convex portions 51, and meanwhile, the sliding space can reduce the precision in production of the base 1 and the distributor 3 and reduce the production cost.

In some examples, the number of guide assemblies 5 may correspond to the number of nozzles 4, i.e., one nozzle 4 is provided on each projection 51 in each guide assembly 5, with one ejector tube 32 for each nozzle 4. At the moment, the base 1 can be used for stably supporting the distributor 3, the distribution of fuel gas in the distributor 3 can be more uniform, the flame combustion is more uniform, and the fuel gas combustion is facilitated.

Referring to fig. 14, a limiting component 7 is further disposed between the protruding portion 51 and the recessed portion 52, and the limiting component 7 is used for limiting the protruding portion 51 and the recessed portion 52 from sliding relatively.
