Description

Technical Field

[0001] The invention relates to the technical field of household kitchenware and to a top-air-inlet gas stove. Background Art

[0002] Gas stove is an indispensable kitchen appliance in modern families, which is convenient for people to cook, steam, fry and process various kinds of food. At present, the burners and pot brackets of most gas stoves are separate and independent. The existing stove burners generally include an inner ring fire cover and an outer ring fire cover. The fire holes of the inner ring fire cover and the outer ring fire cover are often round fire holes that are easier to process. However, when overflowing, the round fire holes are easily blocked, resulting in flameout, uneven fire and other unfavorable working conditions, affecting customer experience and increasing the maintenance rate. In addition, many gas stoves have begun to use upper air intake burners. Since the primary and secondary air required by the upper air intake burners during combustion come from the upper part of the stove panel, the chassis of the gas stove can be fully sealed. Compared with the traditional burner with a lower air intake structure, the completely upper air intake burner is not only safer to use, but also can well solve the problem of stove flameout caused by opening and closing cabinet doors. However, conventional top-inlet burners replenish primary air through the gap between the mixing chamber and the base, which causes the following problems: there is a gap between the mixing chamber and the base. After the mounting screws of the panel are installed, the mounting screws can be seen from the outside of the burner, causing the appearance of the burner to be less than beautiful. In addition, after the gap is set between the base and the mixing chamber, overflow will flow through the gap into the base and the circular basin-shaped body located under the panel, namely the term "bottom cup", which causes many inconveniences for users in maintenance and cleaning. Moreover, if the overflow is not cleared for a long time, it will affect the normal use of the burner.

[0003] In addition, the structure of the "bottom cup" often causes a sharp bend at the connection between the ejection pipe outlet and the mixed gas channel, which significantly increases the ejection resistance. This type of design, such as the Chinese utility model patent "Gas Burner" with patent number ZL201120156854.0 (authorization announcement number CN202082922U), has a poor ejection effect. At the same time, the primary air added from the panel of this type of upper air intake burner enters the "bottom cup" by utilizing the negative pressure generated by the nozzle spraying gas, which can easily cause uneven airflow distribution of the primary air, affecting the primary air flow to a certain extent. The gas coefficient makes the gas pressure flowing out of the fire holes arranged along the circumferential direction of the outer ring fire cover or the inner ring fire cover uneven, resulting in uneven flames of the outer circle fire generated by the outer ring fire cover or the inner circle fire generated by the inner ring fire cover. At the same time, the second ejector tube and the first ejector tube of this type of burner are both integrated with the "bottom cup" or separately arranged with the bottom cup. Regardless of the problem of poor ejection effect caused by the integrated arrangement with the "bottom cup" or the safety hazard caused by air leakage caused by the joints caused by the separate arrangement with the bottom cup, further improvements are needed to the existing upward air inlet burners. In addition, there is a type of Chinese invention patent application with application number 200810220263.8, which discloses "A multi-nozzle, large flow, fully upper air intake embedded household gas stove burner" (publication number CN101446415A). This invention arranges the inner and outer nozzles corresponding to the inner and outer ring ejectors on both sides of the diameter range of the burner, which can effectively improve the limitation of the short length of the ejector tube, and at the same time can realize independent adjustment of the inner and outer fires, and the combustion power is relatively large. The pursuit of high-power upper air intake burners has become a mainstream trend, but because the inner and outer ring ejectors are still arranged in the "bottom cup", the overall height of the burner is still relatively high, and the overall aesthetics is relatively poor. Therefore, in order to reduce the overall height of the burner, further improvements need to be made to the upper air intake burner.

[0004] Due to the different structures and heating parts of appliances such as frying pans and steamers, some pots need to be farther away from the flame, and the existing gas stoves cannot meet the requirements of all appliances such as frying pans and steamers. In addition, since the burner, pot support, knob, etc. are fixed, they cannot be lifted and hidden, and the burner and pot support cannot be well protected, and it is not convenient to clean. To solve this problem, a Chinese utility model "A liftable gas stove" with patent number ZL201520963168.2 (authorization announcement number CN205227415U) includes a stove body, a burner assembly and a control switch assembly are arranged in the stove body, a lifting frame for driving the burner to be lifted and lowered is arranged under the burner of the burner assembly, a rotating frame for driving the lifting frame to be lifted and lowered is arranged on the periphery of the lifting frame, and a power transmission device for driving the rotating frame to rotate is arranged on one side of the rotating frame, the power transmission device drives the rotating frame to rotate forward or reversely, and the rotating frame rotates forward or reversely to drive the lifting frame to rise or fall. The gas stove can realize the overall lifting of the burner and the stove rack. When in use, the burner and the pot support are lifted to meet the use requirements. When not in use, the burner and the stove rack are stored under the stove panel, so that the burner and the stove rack are flush with the stove panel, which can be beneficial to protecting the burner and the pot support and is also convenient for cleaning. It is a Chinese invention patent application with application number 201410660022.0 (application publication number CN104390243A), which changes the structural shape of the traditional embedded gas stove. When in use, the burner and the stove rack are lifted. The basic combustion function of the stove is realized, and the burner and the stove rack can be lowered when not in use and stored under the stove panel, so that the burner is level with the stove rack and the stove panel, forming a flat surface for placing things, which has both dust-proof effect and beautiful appearance. The burner is raised and lowered to adapt to the conversion between cooking state and non-cooking state. When rising, both of these burners must first drive the pot bracket to move upward. After moving a certain distance, the burner moves upward again. Therefore, the movement of the burner and the pot bracket needs to be realized in two steps, which is more cumbersome in operation. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a gas stove capable of shortening the burner lifting operation stroke in view of the above-mentioned prior art status.

[0006] The second technical problem to be solved by the present invention is to provide a gas stove that can be easily cleaned in view of the above-mentioned existing technical status.

[0007] The third technical problem to be solved by the present invention is to provide a gas stove which can effectively avoid the need for the burner and the pot support to have lifting operation strokes respectively in view of the above-mentioned existing technical status.

[0008] The fourth technical problem to be solved by the present invention is to provide a gas stove which can effectively prevent overflow from clogging the fire hole burner in view of the above-mentioned existing technical status.

[0009] The fifth technical problem to be solved by the present invention is to provide a gas stove with a burner capable of improving the uniform mixing of the primary air / gas mixture in view of the above-mentioned prior art status.

[0010] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: the gas stove includes a panel, a burner body and an air supply part for providing mixed gas to the burner body, and is characterized in that: the burner body includes at least two fire cover bodies surrounded in a circle, each of the fire cover bodies has a fire outlet part facing the inner part, and each of the fire cover bodies also has an air mixing chamber connected to the fire outlet part, the head of each fire cover body corresponding to the air inlet end of the air mixing chamber is hinged on the air supply part through a pin shaft, and the tail of each fire cover body corresponding to the air outlet end of the air mixing chamber is connected to a driving mechanism, the driving mechanism is used to lift the tail of each fire cover body, and the end of the driving mechanism is also provided with a connecting part that can extend into the tail of the corresponding fire cover body.

[0011] In order to solve the second technical problem, preferably, the tail of the fire cover body has a slide groove for the connecting part to slide, and when the connecting part of the driving mechanism is out of the slide groove, the head of the fire cover body can be flipped relative to the panel. When the gas stove needs to be cleaned when not cooking, each fire cover body only needs to be flipped relative to the panel.

[0012] Furthermore, the driving mechanism comprises:

[0013] A supporting portion, used to support the connecting portion, the panel having a through hole for the supporting portion to extend out of the panel;

[0014] A mounting portion, located at the bottom of the supporting portion and used for mounting the supporting portion; and

[0015] The driving part is located in the center of the installation part and can drive the installation part to rise and fall. When the driving part drives the installation part to rise and fall, the corresponding supporting part also rises and falls accordingly, so that the connecting part connected to the supporting part slides in the slide groove of the tail of the fire cover body, thereby realizing the raising and lowering of the tail of each fire cover body. For this reason, in the top-down direction, each fire cover body gradually tilts downward toward the adjacent fire cover body, so that a circle of fire cover bodies is surrounded in the form of a bonfire. This design can not only make the fire outlet less likely to be blocked (because the overflow can fall under the action of gravity), but also increase the fire outlet area and improve the combustion efficiency.

[0016] In order to make the overall structure of the burner simpler, preferably, the air supply part includes:

[0017] An air supply pipe, wherein the head of each fire cover body corresponding to the air inlet end of the air mixing chamber is hinged to the air supply pipe through a pin shaft; a nozzle is arranged at the air outlet end of the air supply pipe;

[0018] The air supply channel is used to connect the air supply pipes of each of the fire cover bodies and is connected to the air inlet end of each air supply pipe; and the air inlet pipe is connected to the external gas supply part and the air supply channel respectively. As long as the air inlet pipe is connected to the external gas supply part, the mixed gas of primary air and gas can be transported to each gas supply pipe through the air supply channel, thereby realizing the ignition of each fire cover body.

[0019] In order to accurately control the position of the raised tail of each fire cover body, preferably, a position determination mechanism capable of determining the position of the rear of each fire cover body raised by the driving mechanism is also included.

[0020] Furthermore, the judgment mechanism is arranged in a chassis located below the panel, and a matching part matching with the mounting part of the driving mechanism is arranged on the outer periphery of the tube wall corresponding to the air inlet end of the air supply pipe, and a guide column is arranged at the position of the chassis corresponding to the air supply pipe to limit the mounting part to be lifted and lowered only in the up and down directions, and the lower end of the guide column is connected to the chassis, and the upper end of the guide column is connected to the matching part, and when the driving part drives the mounting part together with the supporting part to move upward to the matching part, the tail of each fire cover body can be prevented from continuing to rise. The air supply pipe cleverly realizes the dual role of "one thing for two purposes", on the one hand, it has the function of air supply, and on the other hand, it also has the matching part constituting the judgment mechanism.

[0021] To solve the third technical problem, preferably, each of the fire cover bodies is in an inverted V-shape and includes a first wall portion that gradually tilts outward from top to bottom and a second wall portion that gradually tilts inward from top to bottom, the fire outlet portion is located at the second wall portion, and the space enclosed between the first wall portion and the second wall portion has the gas mixing chamber that is connected to the fire outlet portion. In order to realize that the fire cover body has the function of a pot holder, the gas mixing chamber enclosed between the first wall portion and the second wall portion of the fire cover body is connected to the fire outlet portion, making the overall fire cover body structure simpler, and through the structural design of the burner itself, the burner has the function of a pot holder, eliminating the pot holder of the existing burner, reducing costs, improving aesthetics, and facilitating user cleaning.

[0022] In order to better prevent the fire outlet from being blocked by the overflowing liquid, preferably, the fire outlet is in the shape of a slit. Compared with a round fire hole, the slit fire hole is conducive to reducing the occurrence of fire hole blockage when the liquid overflows.

[0023] To solve the fourth technical problem, preferably, each of the fire cover bodies is further provided with a shielding portion capable of shielding the fire outlet, the shielding portion of each of the fire cover bodies gradually tilts downward from top to bottom, and the shielding portion has at least two anti-slip stripes, and the tip portion of each of the V-shaped fire cover bodies and the shielding portion together constitute a pot support. The anti-slip stripes of the shielding portion enable the fire cover body to better support the pot.

[0024] Furthermore, the shielding portion and the second wall portion have an angle a, and the angle a is 20° to 30°. If the angle is too small, it cannot effectively prevent the overflow from being blocked, and if it is too large, it is difficult to form a pot support with the tip of each fire cover body.

[0025] To solve the fifth technical problem, preferably, the mixing chamber includes an air intake chamber and a buffer chamber, the air inlet end of the air intake chamber is equipped with an injector, and the air outlet end of the air intake chamber is connected to the fire outlet through the buffer chamber. The burner is formed by at least two fire cover bodies that can form a circle, each fire cover body has a fire outlet facing the inner part, each fire cover body is independently set to facilitate user cleaning, and the setting of the buffer chamber can ensure that the length of the air intake chamber is effectively extended, so that the primary air / gas mixture is mixed more evenly, and the primary air after being evenly mixed in the buffer chamber is mixed with the gas and the primary air to flow out of the fire part, avoiding the gas and the primary air from colliding with each other from different directions, further improving the uniformity of the mixing of the primary air and the gas, and improving the primary air intake rate, while also effectively reducing the kinetic energy loss and making it diffuse evenly, so that the fire outlet of each fire cover body can maintain a stable and uniform flame, so that the flame of the upper air inlet burner is short, uniform and powerful, and there will be no defects such as yellow flame and flashback.

[0026] Compared with the prior art, the advantage of the present invention is that the tail portion of each fire cover body of the burner can be raised and lowered relative to the panel, so that the fire cover bodies formed in a circle are gradually tilted downward toward the adjacent fire cover bodies in the top-down direction, so that the fire cover bodies formed in a circle form a campfire. At the same time, the fire cover bodies formed in a circle can be used as pot supports to support pots. While the tail portion of each fire cover body of the burner can be raised and lowered relative to the panel, the formation of the pot support is also realized. In the non-cooking state, each fire cover body is located on the panel of the gas stove, thereby shortening the operating stroke of the burner lifting and lowering. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention is further described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 11The gas stove of this embodiment includes a panel 1, a burner body and an air supply part 2 for providing mixed gas to the burner body. The burner body includes at least two fire cover bodies 3 arranged in a circle. The inner portion of each fire cover body 3 has a fire outlet 31, and each fire cover body 3 also has a gas mixing chamber 320 connected to the fire outlet 31. The head 32 of each fire cover body 3 corresponding to the gas inlet end 321 of the gas mixing chamber 320 is hinged to the air supply part 2 through a pin 4, and the tail 33 of each fire cover body 3 corresponding to the gas outlet end 322 of the gas mixing chamber 320 is connected to a driving mechanism 5. The driving mechanism 5 is used to raise the tail 33 of each fire cover body 3, and the end of the driving mechanism 5 is also provided with a connecting part 51 that can extend into the tail 33 of the corresponding fire cover body 3. Since the tail portion 33 of each fire cover body 3 of the burner can be raised and lowered relative to the panel 1, each fire cover body 3 in a circle is gradually tilted downward toward the adjacent fire cover body 3 in the direction from top to bottom, so that the fire cover bodies 3 in a circle are formed into a campfire form, and at the same time, the fire cover bodies 3 in a circle can be used as a pot support to support the pot. While the tail portion 33 of each fire cover body 3 of the burner can be raised and lowered relative to the panel 1, the formation of the pot support is also realized, and each fire cover body 3 is located on the panel 1 of the gas stove in the non-cooking state, thereby shortening the operating stroke of the burner lifting and lowering.

[0040] Specifically, the tail portion 33 of the fire cover body 3 has a slide groove 331 for the connection portion 51 to slide, and when the connection portion 51 of the driving mechanism 5 is out of the slide groove 331, the head portion 32 of the fire cover body 3 can be flipped relative to the panel 1. When the gas stove is not in a cooking state and needs to be cleaned, it is only necessary to flip each fire cover body 3 relative to the panel 1. The driving mechanism 5 of this embodiment includes a supporting portion 52 for supporting the connection portion 51, and the panel 1 of the gas stove correspondingly has a through hole 10 for the supporting portion 52 to extend out of the panel 1, a mounting portion 53 located at the bottom of the supporting portion 52 for mounting the supporting portion 52, and a driving portion 54 located at the center of the mounting portion 53 and capable of driving the mounting portion 53 to rise and fall. When the driving part 54 drives the mounting part 53 to rise and fall, the supporting part 52 also rises and falls accordingly, so that the connecting part 51 connected to the supporting part 52 slides in the slide groove 331 of the tail part 33 of the fire cover body 3, thereby realizing the raising and lowering of the tail part 33 of each fire cover body 3. For this reason, when the tail part 33 of each fire cover body 3 is raised, in the direction from top to bottom, each fire cover body 3 gradually tilts downward toward the adjacent fire cover body 3, so that a circle of fire cover bodies 3 are surrounded in the form of a campfire. This design can not only make the fire outlet 31 less likely to be blocked (because the overflow can fall under the action of gravity) on the one hand, but also increase the fire outlet area and improve the combustion efficiency on the other hand. In addition, in order to make the overall structure of the burner simpler, the air supply part 2 includes an air supply pipe 21, and the head 32 of the air inlet end of each fire cover body 3 corresponding to the mixing chamber 320 is hinged on the air supply pipe 21 through a pin shaft 4, a nozzle 22 is arranged at the air outlet end of the air supply pipe 21, and an air supply channel 23 for connecting the air supply pipes 21 of each fire cover body 3. The air supply channel 23 can be connected with the air inlet end of each air supply pipe 21, and also includes an air intake pipe 24 respectively connected with the external gas supply part and the air supply channel 23. As long as the air intake pipe 24 is connected with the external gas supply part, the mixture of primary air and gas can be transported to each air supply pipe 21 through the air supply channel 23, thereby realizing the ignition of each fire cover body 3.In order to accurately control the raised position of the tail portion 33 of each fire cover body 3, a position judgment mechanism is also included which can judge whether the driving mechanism 5 raises the tail portion 33 of each fire cover body 3, wherein the judgment mechanism is arranged in the chassis 6 located under the panel 1, and the outer periphery of the tube wall corresponding to the air inlet end of the air supply pipe 21 is provided with a matching portion 211 which cooperates with the mounting portion 53 of the driving mechanism 5. The matching portion 211 of this embodiment is a lug, and the position of the chassis 6 corresponding to the air supply pipe 21 is provided with a guide column 61 which limits the mounting portion 53 to be able to be lifted and lowered only in the up and down directions. The lower end of the guide column 61 is connected to the chassis 6, and the upper end of the guide column 61 is connected to the matching portion 211. When the driving portion 54 drives the mounting portion 53 together with the supporting portion 52 to move upward to the matching portion 211, the tail portion 33 of each fire cover body 3 can be prevented from continuing to be lifted, wherein the air supply pipe 21 cleverly realizes the dual role of "one thing with two uses", on the one hand, it has the role of air supply, and on the other hand, it also has the matching portion 211 which constitutes the judgment mechanism.

[0041] In order to realize that the fire cover body 3 has the function of a pot support, the gas mixing chamber 320 enclosed between the first wall portion 34 and the second wall portion 35 of the fire cover body 3 is connected to the fire outlet 31, so that the overall structure of the fire cover body 3 is simpler, and through the structural design of the burner itself, the burner has the function of a pot support, the pot support of the existing burner is eliminated, the cost is reduced, the aesthetics is improved, and it is convenient for users to clean. Each fire cover body 3 is in an inverted V-shape and includes a first wall portion 34 that gradually tilts outward from top to bottom and a second wall portion 35 that gradually tilts inward from top to bottom. The fire outlet 31 is located at the second wall portion 35, and the space enclosed between the first wall portion 34 and the second wall portion 35 has a gas mixing chamber 320 connected to the fire outlet 31. In order to better realize that the fire outlet 31 is blocked by overflow, the fire outlet 31 is in a slit shape. Compared with the round fire hole, the use of a slit fire hole is conducive to reducing the occurrence of fire hole blockage when overflowing. Each fire cover body 3 is also provided with a shielding portion 36 that can shield the fire outlet 31. The shielding portion 36 of each fire cover body 3 gradually tilts downward from top to bottom, and the shielding portion 36 has at least two anti-slip stripes 361, and the tip of each V-shaped fire cover body 3 and the shielding portion 36 together constitute a pot support, wherein the anti-slip stripes 361 of the shielding portion 36 can enable the fire cover body 3 to better support the pot. Further, the shielding portion 36 and the second wall portion 35 have an angle a, and the angle a is 20° to 30°. If the angle is too small, it cannot effectively prevent the overflow from being blocked, and if it is too large, it is not easy to form a pot support with the tip of each fire cover body 3. The mixing chamber 320 includes an air inlet chamber 321 and a buffer chamber 323. The air inlet end 321 of the air inlet chamber 321 is equipped with an injector, and the air outlet end 322 of the air inlet chamber 321 is connected to the fire outlet 31 through the buffer chamber 323. The burner is formed by at least two fire cover bodies 3 that can form a circle. The inner portion of each fire cover body 3 has a fire outlet 31. Each fire cover body 3 is independently arranged to facilitate user cleaning, and the arrangement of the buffer chamber 323 can ensure that the length of the air inlet chamber 321 is effectively extended, so that the air can be discharged once. / The gas mixture is mixed more evenly, and the primary air evenly passed through the buffer chamber 323 is mixed with the gas and the primary air and flows out of the fire part 31, avoiding the gas and the primary air from colliding with each other when they converge from different directions, further improving the uniformity of the mixing of the primary air and the gas, and improving the primary air intake rate. At the same time, it can also effectively reduce the kinetic energy loss and make it diffuse evenly, so that the fire part 31 of each fire cover body 3 can maintain a stable and uniform flame, so that the flame of the upper air inlet burner is short, uniform and powerful, and there will be no defects such as yellow flame and flashback.

[0042] In summary, the burner of the present embodiment is different from the existing annular burner. The burner of the present embodiment is formed in a campfire form by three burner fire covers arranged in a circle. Each fire cover body 3 is in an inverted V-shape and includes a first wall portion 34 gradually inclined outward from top to bottom and a second wall portion 35 gradually inclined inward from top to bottom. The fire outlet 31 is located on the second wall portion 35. The space enclosed by the first wall portion 34 and the second wall portion 35 has a gas mixing chamber 320 connected to the fire outlet 31. The gas mixing chamber 320 formed between the first wall portion 34 and the second wall portion 35 of the body 3 is connected to the fire outlet 31. An ignition needle is arranged near the fire outlet 31 of each fire cover body 3. The air inlet pipe 24 and the nozzle 22 can provide mixed gas to each fire cover body 3. When the ignition needle ignites the mixed gas, the fire outlet 31 of each fire cover body 3 can emit fire. The knob for controlling the opening and closing of the driving part 54 of the driving mechanism 5 is located on the panel 1. The specific use process of the gas stove is as follows:

[0043] a. Cooking state: when cooking is required, the knob 100 is turned, and the control part of the gas stove drives the driving part 54 of the driving mechanism 5 to rotate in the clockwise direction. The driving part 54 of this embodiment is a motor, and the power output end of the motor is located in the center of the mounting part 53, so that the motor can drive the mounting part 53 to rotate, and the supporting part 52 cannot rotate under the limiting effect of each guide column 61 and rises upward. At this time, the connecting part 51 is inserted into the sliding groove 331 of the tail 33 of the fire cover body 3 and slides upward to the inlet. And drive the tail portion 33 of the fire cover body 3 to be lifted up. When the driving portion 54 drives the mounting portion 53 together with the supporting portion 52 to move upward to the state of the matching portion 211, the tail portion 33 of each fire cover body 3 can be prevented from continuing to be lifted up. When the three fire cover bodies 3 are lifted up to a working state in the form of a bonfire, the tip portion of each V-shaped fire cover body 3 and the shielding portion 36 together constitute a pot support, wherein the anti-slip stripes 361 of the shielding portion 36 enable the fire cover body 3 to better support the pot for cooking, which can be referred to Figure 8 and 9 ;

[0044] b. Non-cooking state: turn the knob 100 to the closed position. At this time, the control part of the gas stove will drive the motor to rotate counterclockwise, so that the motor can drive the mounting part 53 to rotate in the opposite direction, and the supporting part 52 moves downward along the guide column 61. At this time, the connecting part 51 is inserted into the slide groove 331 of the tail part 33 of the fire cover body 3 and slides downward to drive the tail part 33 of the fire cover body 3 to descend to the panel 1; to clean the panel 1 after finishing cooking, you only need to flip the fire cover body 3 relative to the gas supply pipe 21 for cleaning. Please refer to Fig.10 and 11 .
