The gas range can be divided into a full air inlet gas range and a full upper air inlet gas range according to the supplementary mode of primary air. Wherein, the primary air of the full air intake gas stove comes from the lower part of the cooking bench, and the primary air of the full air intake gas stove comes from the upper part of the cooking bench. When the full air intake gas stove is used, vent holes are reserved on the cabinet and the shell of the gas stove so as to ensure sufficient primary air supplement. However, on one hand, the vent holes are easy to be blocked, so that primary air is insufficient to supplement, gas is insufficient to burn, the carbon monoxide content exceeds the standard, and yellow flame is easy to generate; on the other hand, some foreign matters such as insects easily enter the shell of the gas stove through the vent holes to block the gas pipeline in the gas stove, so that the risk of gas leakage is high. The gas stove with complete upper air inlet does not need to reserve vent holes on the cabinet and the shell of the gas stove, has higher safety and is popular in the market.

In the related art, the gas stove with complete upper air inlet comprises a stove head and a base which are connected with each other, wherein the stove head comprises a gas mixing cavity and an injection pipe communicated with the gas mixing cavity, and a nozzle corresponding to the injection pipe and a supporting structure for supporting the stove head are arranged on the base. The surface of the base close to the furnace end is complex in structure, and inconvenient to clean. And, under the condition that the gas-cooker of air inlet includes the flourishing liquid dish completely, need offer on the flourishing liquid dish and dodge the hole, dodge the structure on the surface that the base is close to the furnace end, in this way, be unfavorable for the design of flourishing liquid dish.

Based on this, as shown in fig. 1, fig. 1 is a structural diagram of a complete upper air intake gas stove according to some embodiments of the present application. The embodiment of the disclosure provides a complete upper air inlet gas stove 100, which can reduce the cleaning difficulty of the complete upper air inlet gas stove 100 and reduce the design difficulty of a liquid containing disc. The full top intake gas cooker 100 includes a burner 1 and a base 2.

Fig. 2 is a cross-sectional view of a full top-intake gas stove according to some embodiments of the present application, as shown in fig. 2. The burner 1 is provided with a first air mixing cavity 11 and a second air mixing cavity 12, and the base 2 is arranged on one side of the burner 1 and is connected with the burner 1 for providing support for the burner 1.

It will be appreciated that the burner 1 may be of a split type structure or an integral type structure, and may be specifically selected according to practical situations, which is not specifically limited in the present disclosure.

Illustratively, as shown in fig. 3, fig. 3 is an exploded view of a burner provided in some embodiments of the present application. The furnace end 1 is split type structure to this kind of mode sets up, is convenient for split the furnace end 1 and cleans, is favorable to reducing the clean degree of difficulty of furnace end 1, and then reduces the clean degree of difficulty of going up air inlet gas-cooker 100 completely.

On this basis, referring to fig. 3, the burner 1 includes a first fire cover 13, a second fire cover 14, and a distributor 15. The first fire cover 13 and the second fire cover 14 are disposed on a side of the distributor 15 away from the base 2 (as shown in fig. 2), and are connected to the distributor 15.

The first fire cover 13 and the distributor 15 enclose a first air mixing cavity 11 (as shown in fig. 2), and a first fire outlet 131 communicated with the first air mixing cavity 11 is formed in the first fire cover 13; the second fire cover 14 and the distributor 15 enclose a second air mixing cavity 12 (as shown in fig. 2), and a second fire outlet 141 communicated with the second air mixing cavity 12 is arranged on the second fire cover 14.

It will be appreciated that the first fire cover 13 is typically provided with a plurality of first fire holes 131, and the second fire cover 14 is typically provided with a plurality of second fire holes 141.

Illustratively, as shown in FIG. 1, the first fire cover 13 is disposed circumferentially around the second fire cover 14. In this case, the plurality of first fire holes 131 are disposed around the plurality of second fire holes 141. In this way, secondary air replenishment is facilitated.

The first fire cover 13 and the second fire cover 14 may be coaxially disposed or non-coaxially disposed, and may be specifically selected according to the actual situation, which is not specifically limited in the present disclosure. For example, the first fire cover 13 and the second fire cover 14 are coaxially disposed. In this way, when the cooker is heated by the full upper air intake gas range 100, the cooker is heated more uniformly, and the cooking effect can be improved.

In some embodiments, as shown in fig. 4, fig. 4 is a cross-sectional view of a base provided by some embodiments of the present application. The base 2 comprises a top plate 21, a first injection pipe 22 and a second injection pipe 23, wherein the top plate 21 is arranged on one side of the furnace end 1 (shown in fig. 2) and is connected with the furnace end 1. The first injection pipe 22 and the second injection pipe 23 are arranged on one side of the top plate 21 far away from the furnace end 1 and are connected with the top plate 21. Wherein the first ejector tube 22 is in communication with the first air mixing chamber 11 (shown in fig. 2) and the second ejector tube 23 is in communication with the second air mixing chamber 12 (shown in fig. 2).

In this way, the fuel gas and air ejected from the first ejector pipe 22 can flow into the first air mixing chamber 11 through the first ejector pipe 22, and after being uniformly mixed, flow out through the first flame outlet 131 communicated with the first air mixing chamber 11, and then be ignited to form flame. Similarly, the fuel gas and air ejected from the second ejector pipe 23 can flow into the second air mixing chamber 12 through the second ejector pipe 23, and after being uniformly mixed, flow out through the second flame outlet 141 communicated with the second air mixing chamber 12, and then be ignited to form flame.

It will be appreciated that in cleaning the base 2 of the fully upper air inlet gas range 100, it is generally only necessary to clean the exposed portions of the base 2, mainly the surface of the side of the base 2 adjacent to the burner 1.

Based on this, setting the first injection pipe 22 and the second injection pipe 23 on the side of the top plate 21 away from the burner 1 can simplify the structure on the surface of the top plate 21 on the side close to the burner 1, thereby making the surface of the base 2 close to the burner 1 smoother. In this way, the cleaning difficulty of the base 2 is advantageously reduced, so that the cleaning difficulty of the gas cooker 100 with complete upward air intake is reduced.

On the basis of this, referring to fig. 4, the base 2 may further include a first nozzle 24 and a second nozzle 25, and the first nozzle 24 and the second nozzle 25 are connected to the top plate 21. Wherein the first nozzle 24 corresponds to the position of the first ejector tube 22 and the second nozzle 25 corresponds to the position of the second ejector tube 23.

The first nozzle 24 corresponds to the position of the first ejector tube 22, and means that the first nozzle 24 is located within the opening of the first ejector tube 22. In this way, the fuel gas emitted from the first nozzle 24 can be directed into the first injection duct 22. Similarly, the position of the second nozzle 25 corresponding to the position of the second ejector pipe 23 means that the second nozzle 25 is located within the opening range of the second ejector pipe 23. In this way, the fuel gas injected from the second nozzle 25 can be introduced directly into the second injection duct 23.

In this case, when the first nozzle 24 injects the fuel gas into the first injection pipe 22, air near the opening of the first injection pipe 22 is injected into the first injection pipe 22 with the fuel gas, and this air is to be introduced as primary air into the first air mixing chamber 11 through the first injection pipe 22 together with the fuel gas, and after being uniformly mixed, flows out through the first flame outlet 131 communicating with the first air mixing chamber 11, and is then ignited to form a flame. Similarly, when the second nozzle 25 injects the fuel gas into the second injection pipe 23, air near the opening of the second injection pipe 23 is injected into the second injection pipe 23 along with the fuel gas, and this air is used as primary air to flow into the second air mixing chamber 12 together with the fuel gas through the second injection pipe 23, and after being uniformly mixed, flows out through the second flame outlet 141 communicating with the second air mixing chamber 12, and is then ignited to form flame.

Illustratively, as shown in fig. 5, fig. 5 is a block diagram of a complete upper air intake gas stove according to some embodiments of the present application. The first nozzle 24 and the second nozzle 25 are disposed on a side of the top plate 21 away from the burner 1, and are connected to the top plate 21. It will be appreciated that the provision of the first nozzle 24 and the second nozzle 25 on the side of the top plate 21 remote from the burner 1 further simplifies the construction on the surface of the top plate 21 on the side closer to the burner 1, thereby making the surface of the base 2 closer to the burner 1 smoother. Thus, the difficulty of cleaning the gas cooker 100 with the full upward air intake can be further reduced.

On this basis, referring to fig. 4, the first nozzle 24 may be disposed coaxially with the first ejector tube 22. In this way, when the first nozzle 24 injects the fuel gas into the first injection pipe 22, the risk of fuel gas leakage can be reduced, and the capability of the first injection pipe 22 to inject primary air can be improved, thereby improving the safety and combustion performance of the full-up-intake gas cooker 100. Likewise, the second nozzle 25 may be disposed coaxially with the second ejector tube 23. In this way, when the second nozzle 25 injects the fuel gas into the second injection pipe 23, the risk of fuel gas leakage can be reduced, and the capability of the second injection pipe 23 to inject primary air can be improved, thereby improving the safety and combustion performance of the complete upper air intake gas stove 100.

In some embodiments, as shown in FIG. 5, the axis of the first injector tube 22 and the axis of the second injector tube 23 are both parallel to the surface of the top plate 21 remote from the burner 1. In this way, it is advantageous to reduce the space occupied by the first and second ejector tubes 22, 23 in a direction perpendicular to the surface of the top plate 21 remote from the burner 1.

On this basis, referring to fig. 6, fig. 6 is a cross-sectional view of a base provided in some embodiments of the present application. The direction along the axis of the first ejector tube 22 (as shown in fig. 4) and directed by the first ejector tube 22 to the first nozzle 24 is taken as a first direction X, and the direction along the axis of the second ejector tube 23 and directed by the second ejector tube 23 to the second nozzle 25 is taken as a second direction Y, and an angle α between the first direction X and the second direction Y is less than or equal to 30 °.

In this way, the openings of the first and second ejector pipes 22, 23 can be concentrated on the same side of the base 2, which is advantageous in that the first and second nozzles 24, 25 are concentrated. Thus, the gas pipeline can be conveniently arranged.

For example, as shown in fig. 6, the angle α between the first direction X and the second direction Y may be any one of 0 °, 5 °, 10 °, 15 °, 20 °, 25 °, and 30 °, and may be specifically selected according to practical situations, which is not specifically limited in the present disclosure.

For example, the angle α between the first direction X and the second direction Y is 0 °. At this time, as shown in fig. 7, fig. 7 is a block diagram of a base provided in some embodiments of the present application. The axis of the first ejector tube 22 is parallel to the axis of the second ejector tube 23. In this way, it is advantageous to reduce the space taken up by the first and second ejector tubes 22, 23 in a direction parallel to the surface of the top plate 21 remote from the burner 1.

At this time, as shown in fig. 5, the axis of the first ejector pipe 22 may be disposed on the side of the axis of the second ejector pipe 23 away from the top plate 21; the axis of the second ejector pipe 23 may be arranged on the side close to the top plate 21; the distance between the axis of the first injection pipe 22 and the surface of the top plate 21 away from the burner 1 may also be set equal to the distance between the axis of the second injection pipe 23 and the surface of the top plate 21 away from the burner 1. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

Illustratively, referring to FIG. 5, the axis of the first ejector 22 is disposed on the side of the axis of the second ejector 23 remote from the top plate 21. In this way, the risk of crossing the gas pipeline can be reduced, and the difficulty of setting the gas pipeline is reduced.

In some embodiments, as shown in fig. 8, fig. 8 is a block diagram of a burner according to some embodiments of the present application. The burner 1 is provided with a first air inlet 16, and the first air inlet 16 is communicated with a first air mixing cavity 11 (shown in fig. 2). Referring to fig. 9, fig. 9 is a block diagram of a base provided in some embodiments of the application. The top plate 21 is provided with a first air outlet 211, and the first air outlet 211 is connected with the first air inlet 16.

On this basis, referring to fig. 10, fig. 10 is a block diagram of a base provided in some embodiments of the present application. The base 2 further comprises a side plate 26 and a bottom plate 27, wherein the side plate 26 is arranged on one side of the top plate 21 away from the burner 1 and is connected with the top plate 21. The side plate 26 is disposed circumferentially around the first air outlet 211. The bottom plate 27 is connected to the side plate 26 and encloses a first premix chamber 28 (shown in FIG. 2) with the side plate 26 and the top plate 21. The first eductor 22 (shown in fig. 4) is in communication with the first premix chamber 28.

In this case, the primary air and the fuel gas ejected from the first ejector tube 22 will flow into the first premixing chamber 28 for preliminary mixing, then flow through the first air outlet 211 and the first air inlet 16 into the first air mixing chamber 11 for further uniform mixing, and finally flow out through the first fire outlet 131 and then be ignited.

In this way, the primary air injected by the first injection pipe 22 can be mixed with the fuel gas more uniformly, which is advantageous for the fuel gas to be fully combusted at the first flame outlet 131. In this way, the risk of exceeding carbon monoxide levels or the occurrence of yellow flames can be reduced.

The top plate 21, the side plate 26, and the bottom plate 27 may be integrally formed, or may be three independent members, and may be integrally connected by welding, adhesion, or the like. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

Illustratively, as shown in fig. 10, the top plate 21, the side plates 26, and the bottom plate 27 are integrally formed. In this manner, the air tightness of the first premix chamber 28 is advantageously improved, thereby reducing the risk of gas leakage and further improving the safety of the fully updraft gas cooker 100.

On this basis, referring to fig. 4, the side plate 26 may include a first sub-side plate 261, a second sub-side plate 262, a third sub-side plate 263, and a fourth sub-side plate 264.

Illustratively, as shown in fig. 4, the first sub-side plate 261 is provided with a first mounting hole, and the first ejector pipe 22 is disposed through the first mounting hole. It will be appreciated that the outer surface of the first injector tube 22 conforms to the inner surface of the first mounting bore, i.e., there is no gap between the surfaces of the first injector tube 22 and the first mounting bore that are adjacent to each other, and that gas within the first premix chamber 28 (shown in FIG. 2) cannot leak out of between the surfaces of the first injector tube 22 and the first mounting bore that are adjacent to each other.

On this basis, the second sub-side plate 262 is disposed opposite to the first sub-side plate 261, and the first air outlet 211 is located between the first sub-side plate 261 and the second sub-side plate 262. The axis of the first ejector pipe 22 is perpendicular to the surface of the second sub-side plate 262 close to the first sub-side plate 261, and the orthographic projection of the first ejector pipe 22 on the surface of the second sub-side plate 262 close to the first sub-side plate 261 is located in the boundary of the second sub-side plate 262.

In this manner, air and fuel flowing from the first injector tube 22 into the first premix chamber 28 will first impinge upon the second sub-side plate 262 and then diffuse to other areas of the first premix chamber 28. In this way, the air and the fuel gas can be mixed more uniformly in the first premixing chamber 28, facilitating the full combustion of the fuel gas.

The third sub-side plate 263 is disposed on a side of the axis of the first ejector pipe 22 away from the first air outlet 211, and is connected to the first sub-side plate 261 and the second sub-side plate 262. The fourth sub-side plate 264 is disposed opposite to the third sub-side plate 263 and is connected to the first sub-side plate 261 and the second sub-side plate 262. The first air outlet 211 is located between the third and fourth sub-side panels 263 and 264.

That is, the first air outlet 211 is surrounded by the first sub-side plate 261, the second sub-side plate 262, the third sub-side plate 263, and the fourth sub-side plate 264. At this time, the first pre-mixing chamber 28 is surrounded by the first sub-side plate 261, the second sub-side plate 262, the third sub-side plate 263, the fourth sub-side plate 264, the bottom plate 27, and the top plate 21.

In some embodiments, as shown in fig. 4, the axis of the first ejector tube 22 is disposed on the peripheral side of the first air outlet 211. That is, the first ejector 22 is not disposed opposite the first air outlet 211.

In this way, the risk that the gas and air injected into the first premix chamber 28 by the first injection pipe 22 do not undergo preliminary mixing, i.e., flow out of the first premix chamber 28 through the first air outlet 211, can be reduced. In this way, it is advantageous to mix the air and the gas more uniformly, so that the combustion of the gas is more complete.

In this case, the surface of the third sub-side plate 263 adjacent to the fourth sub-side plate 264 may be disposed perpendicular to the surface of the top plate 21 adjacent to the side plate 26 and tangential to the inner surface of the first ejector pipe 22.

In this way, the axis of the first ejector tube 22 can be further from the first air outlet 211 with the first ejector tube 22 and the first premix chamber 28 being sized. In this manner, the fuel gas and air can stay in the first premix chamber 28 for a longer period of time, thereby achieving a more uniform mixing.

In some embodiments, as shown in fig. 11, fig. 11 is a block diagram of a base provided in some embodiments of the present application. The fourth sub-side plate 264 includes a connecting portion 2641 and a guide portion 2642. The connection portion 2641 is connected to the second sub-side plate 262, the guide portion 2642 is connected to an end of the connection portion 2641 remote from the second sub-side plate 262, and the guide portion 2642 is connected to the first sub-side plate 261 (shown in fig. 4). That is, the connection portion 2641 is connected to the first sub-side plate 261 through the guide portion 2642.

On this basis, referring to fig. 4, the surface of the guide portion 2642 near the first air outlet 211 is curved and is recessed in a direction away from the first air outlet 211. In this way, it is possible to smoothly transition between the fourth sub-side plate 264 and the first sub-side plate 261. In this way, the gas mixed in the first premixing chamber 28 in the initial stage can flow out from the first air outlet 211 more smoothly, so that the air flow can be more stable, which is beneficial to the stable combustion of flame.

Illustratively, as shown in fig. 4, the curved surface is tangent to the surface of the first sub-side plate 261 near the first air outlet 211 at the junction therebetween, and the curved surface is tangent to the surface of the connecting portion 2641 near the first air outlet 211 at the junction therebetween. In this way, the transition between the fourth sub-side plate 264 and the first sub-side plate 261 can be made smoother.

It is understood that the surface of the guide portion 2642 near the first air outlet 211 may be a plane, and one end away from the connecting portion 2641 is inclined toward the direction approaching the first air outlet 211. In this way, the guiding portion 2642 can also serve to guide the air flow, so that the air in the first premix chamber 28 can flow out from the first air outlet 211. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

In some embodiments, as shown in fig. 8, a second air inlet 17 is further provided on the burner 1, the first air inlet 16 is disposed around the circumference of the second air inlet 17, and the second air inlet 17 communicates with the second air mixing chamber 12 (as shown in fig. 2).

On the basis, referring to fig. 9, the base 2 further includes a connecting member 29, and the connecting member 29 is disposed in the first air outlet 211 in a penetrating manner, and has a gap with an inner surface of the first air outlet 211. That is, the connector 29 does not completely block the first air outlet 211. In this way, the air in the first premixing chamber 28 can flow out through the gap between the connecting piece 29 and the inner surface of the first air outlet 211, and then can flow into the first mixing chamber 11 normally.

Wherein, the connecting piece 29 has a second premixing chamber 291 (as shown in fig. 2) inside, and a second air outlet 292 is disposed on a surface far from the bottom plate 27, and the second air outlet 292 is communicated with the second premixing chamber 291. The second air outlet 292 is connected to the second air inlet 17.

On this basis, the side plate 26 is provided with a second mounting hole, and the second injection pipe 23 is arranged in the second mounting hole in a penetrating manner and is connected with the connecting piece 29. The second ejector tube 23 communicates with the second premix chamber 291.

In this case, the air and the gas ejected from the second ejector pipe 23 will flow into the second premixing chamber 291 for preliminary mixing, then flow through the second air outlet 292 and the second air inlet 17 to enter the second air mixing chamber 12 for further uniform mixing, and finally flow out through the second flame outlet 141 and then be ignited.

In this way, the primary air injected by the second injection pipe 23 can be mixed with the fuel gas more uniformly, which is advantageous for the fuel gas to be fully combusted at the second flame outlet 141. In this way, the risk of exceeding carbon monoxide levels or the occurrence of yellow flames can be reduced.

The connecting member 29 may be a column, or may be other regular or irregular shape, and may be specifically selected according to practical situations, which is not specifically limited in the present disclosure.

It will be appreciated that the outer surface of the second ejector tube 23 is in contact with the inner surface of the second mounting hole, i.e. there is no gap between the surfaces of the second ejector tube 23 and the second mounting hole that are adjacent to each other, and that gas in the second premix chamber 291 cannot leak out from between the surfaces of the second ejector tube 23 and the second mounting hole that are adjacent to each other.

On this basis, referring to fig. 2, a gap may be provided between the connection member 29 and the bottom plate 27, that is, two surfaces of the connection member 29 and the bottom plate 27, which are close to each other, are not in contact, and gas may flow between the two surfaces. In this way, the volume of the first premix chamber 28 can be increased, which is advantageous in that the primary air and the gas in the first premix chamber 28 are mixed more uniformly.

In the case where the first mounting hole is provided in the first sub-side plate 261, the second mounting hole may be provided in the first sub-side plate 261. In this way, the first ejector 22 and the second ejector 23 are advantageously arranged side by side. Thus, the space occupied by the first injection pipe 22 and the second injection pipe 23 can be reduced, and the structure of the base 2 is more compact; can also provide convenience for the arrangement of gas pipeline, reduce the risk that the pipeline appears alternately.

In some embodiments, referring to fig. 9, the base 2 further comprises an annular protrusion 3. The annular projection 3 is provided on a side of the top plate 21 near the burner 1 (shown in fig. 2), and is provided around the peripheral side of the first air outlet 211. The annular bulge 3 is connected with the furnace end 1, so that the base 2 can better support the furnace end 1, and the installation reliability of the furnace end 1 is improved.

Wherein the annular protrusion 3 may be regarded as an extension of the first air outlet 211 in a direction approaching the burner 1. In this way, the connection of the first air outlet 211 and the first air inlet 16 is facilitated.

In this case, the connecting piece 29 may be provided in a columnar shape and coaxially provided with the annular projection 3. In this way, the connection between the first air inlet 16 and the first air outlet 211 and the connection between the second air inlet 17 and the second air outlet 292 can be conveniently achieved by only arranging the first air inlet 16 around the second air inlet 17 and coaxially arranging the first air inlet 16 and the second air inlet 17.

In this way, the structure of the distributor 15 and the fire cover can be simplified, so that the design difficulty of the furnace end 1 is reduced; and is advantageous in matching the base 2 with the general distributor 15 and fire cover, thereby improving the versatility of the base 2.

It should be noted that, the first air inlet 16 may be communicated with the first air mixing cavity 11 through a plurality of coaxially arranged channels, so that the air pressure in the first air mixing cavity 11 can be more balanced, which is beneficial to the stable combustion of flame.

In some embodiments, as shown in fig. 9, a first air suction opening 212 is further provided on the top plate 21, referring to fig. 12, and fig. 12 is a structural diagram of a base provided in some embodiments of the present application. The base 2 further comprises a first wind deflector 41 (shown in fig. 6) and a first cover plate 42. The first wind deflector 41 is provided on a side of the top plate 21 away from the burner 1, and is connected to the top plate 21.

Referring to fig. 13, fig. 13 is a block diagram of a base according to some embodiments of the present application. The first wind deflector 41 is disposed around the first air intake 212, and the first cover plate 42 is connected to the first wind deflector 41 and encloses the first ejection chamber 4 with the first wind deflector 41 and the top plate 21. The two ends of the first ejector tube 22 and the first nozzle 24 which are close to each other are located in the first ejector chamber 4.

In this manner, the high velocity moving air stream reduces the air pressure in the first eductor chamber 4 as the first nozzle 24 injects fuel into the first eductor 22, thereby creating a negative pressure in the first eductor chamber 4. Thus, the air on the side of the top plate 21 close to the burner 1 can flow into the first injection cavity 4 through the first air suction port 212 under the action of the atmospheric pressure, so as to realize the supplement of primary air. In this way, the full up-draft gas cooker 100 is facilitated to achieve primary air ingress from above the countertop, thereby eliminating the need for a vent hole in the cabinet.

It will be appreciated that the first wind deflector 41 and the first cover plate 42 may be integrally formed with the top plate 21, or may be three separate members, which are integrally connected by welding, bonding, or the like. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

Illustratively, as shown in fig. 11, the first wind deflector 41 and the first cover plate 42 are integrally formed with the roof panel 21. In this way, the air tightness of the first ejection chamber 4 is advantageously improved, so as to improve the ejection effect, and make the primary air supplement more sufficient to enable the fuel gas to burn sufficiently.

On the basis, referring to fig. 13, the base 2 may further include a first baffle 43, where the first baffle 43 is disposed on a side of the top plate 21 near the burner 1 and is connected to the top plate 21. The first baffle 43 is disposed around the first suction port 212.

In this way, the first baffle 43 is able to block liquid dripping onto the top plate 21 during cooking, thereby reducing the risk of liquid entering the first ejection chamber 4 through the first suction opening 212 causing blockage of the first nozzle 24. In this way, the risk of gas leakage can be reduced, thereby improving the safety of the fully upwind gas cooker 100.

It will be appreciated that the first baffle 43 may also be integrally formed with the top plate 21.

Illustratively, as shown in fig. 14, fig. 14 is a block diagram of a full up-intake gas cooker according to some embodiments of the application. The end of the first baffle 43 away from the top plate 21 is abutted with the burner 1, and a first air inlet opening 431 is formed in the first baffle 43, and the first air inlet opening 431 is formed in the end of the first baffle 43 away from the top plate 21. In this way, the first baffle 43 can provide support for the burner 1, thereby improving the reliability of the installation of the burner 1.

At this time, when the gas cooker 100 is completely operated, air can flow into the first injection cavity 4 through the first air inlet opening 431 and the first air inlet 212 in sequence, so as to supplement primary air.

The first air inlet opening 431 may be disposed on a side of the first baffle 43 away from the first air outlet 211, so that the blocking of the air by the burner 1 can be reduced, which is more beneficial to the replenishment of primary air.

In some embodiments, as shown in fig. 9, the top plate 21 is provided with a second air suction opening 213, and referring to fig. 12, the base 2 further includes a second air deflector 44 (as shown in fig. 6) and a second cover plate 45. The second wind deflector 44 is disposed on a side of the top plate 21 away from the burner 1, and is connected to the top plate 21.

Wherein, referring to fig. 13, the second wind deflector 44 is disposed around the circumference of the second wind suction port 213. The second cover plate 45 is connected with the second wind deflector 44, and encloses the second ejection chamber 5 with the second wind deflector 44 and the top plate 21. Two ends of the second injection pipe 23 and the second nozzle 25, which are close to each other, are positioned in the second injection cavity 5.

In this way, the air flow moving at high speed can reduce the air pressure in the second ejection chamber 5 when the second nozzle 25 ejects the fuel gas into the second ejection pipe 23, thereby creating a negative pressure in the second ejection chamber 5. Thus, the air on the side of the top plate 21 close to the burner 1 can flow into the second injection cavity 5 through the second air suction opening 213 under the action of the atmospheric pressure, so as to realize the supplement of primary air. In this way, the full up-draft gas cooker 100 is facilitated to achieve primary air ingress from above the countertop, thereby eliminating the need for a vent hole in the cabinet.

The first wind deflector 41 and the second wind deflector 44 may partially overlap.

It will be appreciated that the second wind deflector 44 and the second cover 45 may be integrally formed with the roof panel 21, or may be three separate members integrally connected by welding, bonding, or the like. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

Illustratively, as shown in fig. 11, the second wind deflector 44 and the second cover plate 45 are integrally formed with the roof panel 21. In this way, the air tightness of the second ejection chamber 5 is advantageously improved, so as to improve the ejection effect, and make the primary air supplement more sufficient to enable the fuel gas to burn sufficiently.

On the basis, referring to fig. 13, the base 2 may further include a second baffle 46, where the second baffle 46 is disposed on a side of the top plate 21 near the burner 1 and is connected to the top plate 21. The second baffle 46 is disposed around the second suction port 213.

In this way, the second baffle 46 is able to block liquid dripping onto the top plate 21 during cooking, thereby reducing the risk of liquid entering the second ejection chamber 5 through the second suction opening 213 causing blockage of the second nozzle 25. In this way, the risk of gas leakage can be reduced, thereby improving the safety of the fully upwind gas cooker 100.

Note that the first baffle 43 and the second baffle 46 may partially overlap.

It will be appreciated that the second baffle 46 may also be integrally formed with the top plate 21.

As shown in fig. 14, an end of the second baffle 46 away from the top plate 21 abuts against the base 2, and a second air inlet opening 461 is formed in the second baffle 46, and the second air inlet opening 461 is disposed at an end of the second baffle 46 away from the top plate 21. In this way, the second baffle 46 can provide support for the burner 1 to improve the reliability of the installation of the burner 1.

At this time, when the gas cooker 100 is completely operated, air may flow into the second injection chamber 5 through the second air inlet opening 461 and the second air intake 213 in sequence, so as to supplement primary air.

The second air inlet opening 461 may be disposed on a side of the second baffle 46 away from the first air outlet 211, so that the blocking of air by the burner 1 can be reduced, which is more beneficial to the replenishment of primary air.
