[0002] An integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, a gas stove, and even a disinfection cabinet and a storage cabinet. It has the advantages of saving space and good fume extraction. Most existing integrated stoves are integral structures, with the main unit, head, and stove fixedly assembled together. During installation, it is usually necessary to cut off the countertop of the cabinet so that a space can be left for the integrated stove, which destroys the integrity of the cabinet countertop. The Chinese invention patent with application number CN201610707028.8 (publication number CN106152180A) discloses a split integrated stove and an integral countertop cabinet. The patent ensures the integrity of the cabinet countertop by separating the main unit, head, and stove of the integrated stove. However, this installation method makes the integrated stove split, which deviates from the original intention of the integrated stove. It can be seen that the installation structure of the existing integrated stove needs to be improved. Summary of the invention

[0045] The present invention is further described in detail below with reference to the accompanying drawings.

[0046] like Figures 1 to 19 As shown, an integrated stove with a cooking device includes a stove and a cooking device arranged below the stove, the stove includes a bottom plate 12 and a panel 11 covering the opening of the bottom plate 12, the cooking device includes a housing 2 and a door body 22 covering the front opening of the housing 2, the bottom wall of the bottom plate 12 is fixedly connected to the top wall of the housing 2, and in this embodiment, the two are fixed together by screws (not shown). In addition, a table 30 is included, and a mounting opening 31 is opened on the table 30. The stove bottom plate 12 has an outwardly extending edge 122 at the outer edge of its opening, and the edge 122 is supported on the periphery of the table mounting opening 31. In this embodiment, the table 30 is the top surface of the cabinet 3.

[0047] In this embodiment, the integrated stove is installed in the cabinet 3, and a mounting opening 31 with closed edges is provided on the countertop 30 of the cabinet 3, and the integrated stove is installed in the mounting opening 31. Preferably, the door body 22 is located below the countertop 30, and the projection of the door body 22 on the countertop 30 in the vertical direction in the closed state is at least partially located outside the periphery of the mounting opening 31 of the countertop 30. When installed in this way, the integrated stove is placed in the mounting opening 31 of the cabinet 3 from top to bottom except for the stove panel 11 and the door body 22 of the cooking device. The above arrangement enables the upper end of the stove to be supported on the periphery of the mounting opening 31, while the other parts of the integrated stove are located below the mounting opening 31. Then, the panel 11 of the stove is installed on the opening of the chassis 12, and the door body 22 is installed on the opening of the housing 2. This installation method can realize the installation of the integrated stove without interrupting the countertop 30 of the cabinet 3, so that the integrity of the countertop 30 of the cabinet 3 is better, and the original shape and style of the cabinet 3 can be maintained.

[0048] The stove also includes a burner, which includes a nozzle exposed on the panel 11 and a burner body 5 arranged above the nozzle, and the burner body 5 is a completely upper air intake burner. The burner body 5 includes a base 51, an annular outer ring fire cover 52, an inner ring fire cover 53, an outer ring ejector pipe 54, an inner ring ejector pipe 55 and an ignition needle 56. The base 51 has a central cavity 511 and an annular cavity 512 surrounding the outer periphery of the central cavity 511. The central cavity 511 and the annular cavity 512 are both open at the top, and the inner ring fire cover 53 and the outer ring fire cover 52 are respectively covered on the central cavity 511 and the annular cavity 512 to form an inner ring mixing cavity 5110 and an outer ring mixing cavity 5120, respectively. The inner ring mixing cavity 5110 and the outer ring mixing cavity 5120 are respectively connected to the inner ring ejector pipe 55 and the outer ring ejector pipe 54. In this embodiment, there are two outer ring ejector tubes 54, each outer ring ejector tube 54 is communicated with the outer ring gas mixing chamber 5120, and the two outer ring ejector tubes 54 are arranged transversely to each other, and the air inlets 128 of the two outer ring ejector tubes are staggered. The provision of two outer ring ejector tubes 54 can improve the ejection efficiency of the outer ring fire cover 52. The two outer ring ejector tubes 54 are arranged transversely, so that the air outlet of each outer ring ejector tube 54 can directly extend into the outer ring gas mixing chamber 5120, reducing the energy loss of the mixed gas in the outer ring ejector tube 54 during the transmission process, ensuring the efficient ejection of the outer ring ejector tube 54, and the air inlets 128 of the two outer ring ejector tubes 54 are staggered, so as to avoid mutual interference between the two, and further improve the ejection efficiency.

[0049] The cross-sectional size of the outer ring mixing chamber 5120 changes alternately along the circumferential direction in an increasing and decreasing manner, and the air outlets of each outer ring ejector tube 54 are respectively located at the maximum point of the cross-sectional area of ​​the outer ring mixing chamber 5120, and the decreasing direction of the cross-sectional area of ​​the outer ring mixing chamber 5120 of both outer ring mixing chambers 5120 is clockwise or counterclockwise. In this way, the two airflows flowing out of the two outer ring ejector tubes 54 can flow in the same direction (clockwise or counterclockwise) and mix with each other as the internal shape of the outer ring mixing chamber 5120 changes, thereby increasing the ejection effect. The alternating change of the cross-sectional area of ​​the outer ring mixing chamber 5120 can be achieved in a variety of forms. For the convenience of processing and manufacturing, preferably, the bottom surface of the annular cavity 512 is formed with protrusions 5121 and grooves 5122 that are alternately spaced along the circumferential direction. Furthermore, each of the above grooves 5122 is inclined from outside to inside and its width decreases in a clockwise or counterclockwise direction. The height of the protrusion 5121 adjacent to each groove 5122 increases in the same direction as the groove 5122, and its width also increases synchronously. A pair of adjacent grooves 5122 and protrusions 5121 are assembled into a circular arc section of the bottom surface of the annular cavity 512, so that the two airflows flowing out of the two outer ring ejector tubes 54 can rotate and flow in the same direction in the outer ring mixing cavity 5120, so that the two airflows can better promote each other and further enhance the ejection effect. In addition, the alternating change of the outer ring mixing cavity 5120 can reduce the volume of the outer ring mixing cavity 5120 to a certain extent, thereby preventing the explosion phenomenon caused by the excessive volume of the outer ring mixing cavity 5120 during the combustion process.

[0050] Furthermore, the end face at the highest point of the above-mentioned protrusion 5121 is a vertical face, that is, the side where the air outlet of each outer ring ejector tube 54 enters the outer ring air mixing chamber 5120 is a vertical face 5123, thereby reducing the resistance at the air outlet of the outer ring ejector tube 54, which is conducive to the airflow entering the outer ring air mixing chamber 5120 and flowing along the outer ring air mixing chamber 5120.

[0051] The ejection structure of the same burner body is fixed, and the gas supply pressure of different gas pipelines is different, and high or low gas pressure will lead to abnormal combustion conditions such as flame separation or flashback. In order to increase the adaptability of the burner body, the burner body for gas stoves in the prior art generally adopts a damper structure, and the damper generally adopts a damper plate and a throttle plate structure to cooperate with the bottom plate opening to achieve the adjustment of the damper. For example, the Chinese invention patent with patent number ZL200520117213.9 (authorization announcement number CN2869625Y) discloses a device for adjusting the damper of a gas stove, which includes a damper plate arranged at the air inlet of the ejection pipe of the gas stove, characterized in that the periphery of the damper plate has at least one arc edge with the rotation center of the damper plate as the center of the circle, and the arc edge is provided with saw teeth with uniform intervals along the circumference, and the arc edge is meshed with a worm through the saw teeth thereon, and the worm is installed in the gas stove through a worm fixing mechanism, and its lower end extends out of the bottom shell of the gas stove. This damper structure needs to be operated under the chassis, which is very inconvenient to operate, and the opening of the chassis will cause problems such as flameout and insects entering when opening and closing the cabinet door. Therefore, in this embodiment, the inner ring ejector tube 55 is vertically penetrated at the center of the ring cavity 512. In addition, an adjustment member 57 is provided in the inner ring mixing cavity 5110. The distance between the adjustment member 57 and the air outlet of the inner ring ejector tube 55 is adjustable. Moreover, since the primary air coefficient of the atmospheric burner body is usually 0.45 to 0.75, the distance D between the adjustment member 57 and the air outlet of the inner ring ejector tube 55 is -2mm≤D≤2mm. The distance D=2mm means that the adjusting member 57 is located above the air outlet of the inner ring ejector tube 55, and the distance D between the bottom end of the adjusting member 57 and the air outlet of the inner ring ejector tube 55 is 2mm. The distance D=-2mm means that the adjusting member 57 extends into the air outlet of the inner ring ejector tube 55, and the distance D between the bottom end of the adjusting member 57 and the air outlet of the inner ring ejector tube 55 is 2mm. Moreover, when -2mm≤D≤0, the distance between the adjusting member 57 and the air outlet of the inner ring ejector tube 55 is in a decreasing relationship with the primary air coefficient ejected by the inner ring ejector tube 55, that is, when the distance D increases, the primary air coefficient decreases, and when the distance D decreases, the primary air coefficient increases. In this embodiment, the adjusting member 57 is a cylinder, and the maximum diameter R of the adjusting member 57 is ≤6mm, because when R is greater than 6mm, the primary air coefficient is less than 0.45, and the combustion condition deteriorates sharply. The inner ring ejector tube 55 includes a trumpet section 551, a roar hole and a diffuser section 553 from bottom to top. In the present embodiment, when the adjusting member 57 extends into the air outlet of the inner ring ejector tube 55 and continues to penetrate into the inner ring ejector tube 55, it can always be located in the air outlet of the inner ring ejector tube 55. Preferably, the length of the adjusting member 57 can penetrate into the diffuser section 553 of the inner ring ejector tube 55, so that the ejection capacity of the inner ring ejector tube 55 can be adjusted by adjusting the length of the diffuser section 553.Further preferably, the length of the adjustment member 57 can further penetrate into the roar port 552 of the inner ring ejector tube 55 , so that the intake amount of the primary air can be further adjusted by adjusting the size of the roar port 552 .

[0052] Further, in this embodiment, the inner ring fire cover 53 includes a cylindrical seat body 531 and an end cover 532 sealed on the top opening of the seat body 531, and an inner ring fire hole 530 is circumferentially arranged on the side wall of the seat body 531. The adjusting member 57 is a column, and an adjusting sleeve 5321 extends vertically downward on the lower surface of the end cover 532. The upper end of the adjusting member 57 is threadedly connected to the adjusting sleeve 5321, so that the relative distance between the adjusting member 57 and the inner ring ejection tube 55 can be adjusted by adjusting the relative position between the adjusting member 57 and the adjusting sleeve 5321. In this embodiment, the free end of the adjusting member 57 is enlarged to form an end cap 571, that is, the maximum diameter of the adjusting member 57 is at its end cap 571. Specifically, in this embodiment, the adjusting member 57 is a screw.

[0053] In this embodiment, the top edge of the inner ring fire cover 53 is recessed radially inwardly along the circumferential direction to form a first ring groove 533, and the first ring groove 533 is placed on the ring wall of the central cavity 511. The top edges of the two side cavity walls of the ring cavity 512 are recessed inwardly along the circumferential direction to form second ring grooves 5123, and the bottom edges of the inner ring wall 522 and the outer ring wall 523 of the outer ring fire cover 52 are respectively placed on the corresponding second ring grooves 5123. The inner and outer ring fire covers 53, 52 are buckled with the base 51 up and down to form an integral part by riveting.

[0054] The outer ring fire cover 52 is provided with an outer ring fire hole 520, the depth of which is small and less than or equal to 2 mm. In this embodiment, the small depth of the outer ring fire hole 520 is achieved by a thin plate structure, that is, the entire outer ring fire cover 52 in this embodiment adopts a thin plate structure. The small depth of the outer ring fire hole 520 can reduce the resistance at the outer ring fire hole 520, thereby reducing the resistance at the air outlet of the outer ring ejector tube 54, and further improving the ejection strength of the outer ring ejector tube 54. The outer ring fire cover 52 includes a fire cover body, which includes an annular top wall 521 and an inner ring wall 522 and an outer ring wall 523 extending downwardly from the inner and outer edges of the top wall 521, respectively, and the top wall 521 is inclined from the inside to the outside along the circumferential direction. The outer ring fire hole 520 is arranged on the top wall 521, so as to effectively prevent the overflow from remaining on the outer ring fire cover 52 and prevent the outer ring fire hole 520 from being blocked by the overflow.

[0055] The outer ring fire holes 520 are small holes and their channels are inclined outward from bottom to top. The outer ring fire holes 520 are arranged circumferentially on the top wall 521 of the outer ring fire cover 52 and arranged in parallel up and down to form a flame zone 524. The flame zone 524 is located at the upper part of the top wall 521 and the outer end of the flame zone 524 is provided with anti-burning zones 525 at intervals along the circumference to prevent the legs of the pot support from being burned. The outer ring fire holes 520 use multiple rows of small holes arranged inside and outside to increase the contact area between the flame and the air, ensuring that the mixed gas of the gas and the air is fully in contact with the secondary air, thereby ensuring the full combustion of the gas and avoiding the problem of yellow flames, and making the flame temperature more uniform. Preferably, the hole spacing between each adjacent outer ring fire hole 520 is less than or equal to twice the aperture of the outer ring fire hole 520. In this embodiment, due to the small depth of the outer ring fire hole 520, the small gas resistance will lead to the problem of too fast gas outlet speed. The outer ring fire hole 520 adopts a small hole structure and is arranged in multiple rows. The flames of each outer ring fire hole 520 can interact with each other to form a strong self-stabilizing flame effect. Even if the local fire hole is blocked, the flame can still burn stably. In this embodiment, the aperture of the outer ring fire hole 520 is less than or equal to 1.6mm, the depth of the outer ring fire hole 520 is less than or equal to 2mm, and the fire hole thermal intensity is 3 to 5×103kW / mm2. The combined effect can effectively solve the risk of flashback and effectively improve the adaptability of the burner body 5 to changes in gas pressure and fluctuations in gas composition.

[0056] The upper end of the inner ring wall 522 of the outer ring fire cover 52 is provided with a fire transfer groove 526 extending up and down, the fire transfer groove 526 is connected with the outer ring gas mixing chamber 5120, and the upper end of the fire transfer groove 526 is adjacent to the flame zone 524. In this embodiment, the inner ring wall 522 of the outer ring fire cover 52 is formed by the inner edge of the top wall 521 of the outer ring fire cover 52 being inclined downward from outside to inside to form an inclined ring wall 527, the inner edge of the inclined ring wall 527 extending vertically downward to form a vertical ring wall 528, the inclined ring wall 527 and the vertical ring wall 528 constitute the inner ring wall 522, and the fire transfer groove 526 is extended from the inner edge of the inner ring wall 522 from outside to inside to the upper part of the vertical ring wall 528, so that the fire transfer groove 526 can be as close to the inner ring fire cover 53 as possible, thereby improving the success rate of fire transfer from the inner ring to the outer ring. The width of the fire transfer groove 526 increases from the outside to the inside, so that the air outlet on the inside of the fire transfer groove 526 is larger, thereby ensuring the success rate of fire transfer from the inner ring to the outer ring, and the air outlet on the outside of the fire transfer groove 526 is smaller, thereby reducing the interference of the fire transfer groove 526 with the secondary air required by the outer ring fire hole 520. Preferably, in this embodiment, the above-mentioned fire transfer grooves 526 are arranged in parallel, thereby improving the stability of fire transfer. In addition, in this embodiment, the above-mentioned fire transfer grooves 526 are arranged above the outer ring ejector tube 54, thereby reducing the interference of secondary air on the inner fire transfer gas, making the fire transfer more stable, while reducing the influence of the fire transfer flame on the secondary air.

[0057] An annular gap is left between the annular cavity 512 and the central cavity 511. An annular cover body 58 centered on the central cavity 511 is arranged in the annular gap, and the edge of the upper port of the cover body 58 is connected to the outer peripheral surface of the annular cavity 512 as a whole. Two outer ring ejection tubes 54 are respectively arranged at the bottom of the cover body 58, and the top surface of each outer ring ejection tube 54 is connected to the bottom surface of the cover body 58 as a whole, so that secondary air passages 59 surrounded by the bottom surface of the bottom wall of the annular cavity 512 and the top surface of the cover body 58 are formed on both sides of the bottom of the base 51. An assembly port 581 is provided on the cover body 58, and the ignition needle 56 is installed in the assembly port 581. In this way, the combustion of the flame of the inner ring fire hole 530 can be promoted through the secondary air passage 59, and it can play a role in auxiliary ignition. In addition, the provision of the cover body 58 can achieve the diversion of primary air and secondary air, preventing the post-combustion gas mixture from mixing into each ejector tube, thereby ensuring the normal combustion of the burner body 5.

[0058] Further, preferably, the top surface of the cover body 58 is inclined from top to bottom along the circumferential direction, and the bottom surface of the bottom wall of the annular cavity 512 corresponding to each secondary air channel 59 is inclined upward from outside to inside, so that each secondary air channel 59 is inclined upward, thereby reducing the length of each secondary air channel 59, thereby reducing the resistance of air flow. In addition, during the combustion process, the temperature of the air around the burner body 5 increases as the distance from the burner body 5 decreases, and gradually increases as the pressure acts, and the obliquely upward secondary air channel 59 is close to the hot secondary air flow direction, thereby reducing the energy loss in the flow.

[0059] Furthermore, the bottom surface of the bottom wall of the annular cavity 512 corresponding to each secondary air channel 59 spirally rises from the outer ring ejector tube 54 on one side to the outer ring ejector tube 54 on the other side, so that the airflow forms a vortex in the secondary air channel 59, which can then reduce the speed of the secondary air inner ring fire hole 530, further enhancing the role of stabilizing flame and assisting ignition.

[0060] In this embodiment, in order to enable the airflow to flow better in each secondary air channel 59, the upper surface of the outer end of each outer ring ejector tube 54 is recessed downward and the cover body 58 is covered on the top surface of the outer ring ejector tube 54. The edge of the upper port of the cover body 58 forms a smooth connection with the outer peripheral surface of the annular cavity 512, and the upper surface of the cover body 58 and the bottom surface of the bottom wall of the annular cavity 512 are both smooth, so that the airflow can be better guided to flow along the secondary air channel 59 under the effect of wall adhesion.

[0061] The side walls of the air inlet of each outer ring ejector tube 54 extend outward in the circumferential direction to form a first baffle wall 582, and the upper edge of the first baffle wall 582 is connected to the bottom surface of the cover body 58 as a whole. The outer edge of the first baffle wall 582 is located at the bottom of the cover body 58, and the outer edge extends toward the other side along the circumferential direction of the cover body 58 to form a second baffle wall 583, the free end of the second baffle wall 583 is sleeved on the outer ring ejector tube 54 and connected to the outer circumferential surface of the outer ring ejector tube 54 as a whole, and the upper edge of the second baffle wall 583 is connected to the bottom surface of the cover body 58 as a whole. Through the arrangement of the first baffle wall 582 and the second baffle wall 583, the space at the bottom of the cover body 58 is separated, so that the air inlet of each outer ring ejector tube 54 forms an independent air intake space, ensuring sufficient primary air injection and avoiding the phenomenon of two outer ring ejector tubes 54 snatching air. A nozzle holder 50 is provided below the cover body 58, and includes a disc-shaped base 501. An air intake gap is formed between the lower edge of each second baffle wall 583 and the top surface of the base 501. Preferably, the lower edge of each second baffle wall 583 is wavy, which not only makes the appearance of the burner body 5 beautiful, but also promotes the entry of primary air into the space separated by the first baffle wall 582 and the second baffle wall 583, and prevents overflow from flowing downward along the surface of the cover body 58 and the second baffle wall 583 to block the air intake gap. In addition, a pad 5831 is provided at the bottom of both ends of each second baffle wall 583, and the bottom of each pad 5831 is respectively against the top surface of the base 501. Each pad 5831 can vertically position the burner body 5, thereby improving the stability of the burner body 5 installation, and can reduce the downward heat transfer during the combustion process, thereby improving the thermal efficiency and reducing the impact on the heat load.

[0062] An inner ring nozzle 502 is vertically arranged at the center of the top surface of the base 501 of the cooking seat, and the inner ring ejector tube 55 is located above the inner ring nozzle 502, and the gas outlet of the inner ring nozzle 502 is opposite to the air inlet of the inner ring ejector tube 55. An outer ring nozzle 503 is arranged on both sides of the inner ring nozzle 502, and the gas outlet of each outer ring nozzle 503 is opposite to the air inlet of the corresponding outer ring ejector tube 54. In addition, each outer ring nozzle 503 is positioned with the cover body 58 through a snap-fit ​​structure, so as to facilitate the assembly of the nozzle seat 50 and the burner body 5. Specifically. In this embodiment, a positioning protrusion 5031 is respectively arranged on the top of each outer ring nozzle 503, and a positioning groove 584 for the corresponding positioning protrusion 5031 to be snapped into is respectively arranged at the corresponding position of the bottom surface of the cover body 58.

[0063] The above-mentioned ignition needle 56 is vertically arranged on the nozzle seat 50, and the upper end of the ignition needle 56 passes through the positioning hole 585 on the above-mentioned cover body 58. The ignition needle 56 includes a protective shell 560 and an electrode needle inserted in the protective shell 560, one end of the electrode needle is exposed to the protective shell 560, and the electrode needle includes a first electrode needle 561 as a discharge end and a second electrode needle 562 that can be used as a receiving end, and the length of the first electrode needle 561 is shorter than that of the second electrode needle 562. In the assembled state, the first electrode needle 561 and the second electrode needle 562 both extend vertically upward and then bend toward the inner ring fire cover 53, and the bending parts of the two are inclined in opposite directions relative to the inner ring fire cover 53, and the distance from the end of the first electrode needle 561 to the inner ring fire cover 53 is smaller than the distance from the end of the second electrode needle 562 to the inner ring fire cover 53, and the distance between the end of the first electrode needle 561 and the end of the second electrode needle 562 is the shortest distance between the two. Thus, the first electrode needle 561 can discharge preferably to the inner ring fire cover 53, and when the circuit of the burner body 5 is blocked due to foreign matter, the circuit can be conducted through the second electrode needle 562, thereby improving the ignition success rate and ensuring the normal operation of the burner body 5. In this embodiment, the protective shell 560 is a ceramic body.

[0064] Furthermore, the overall shape of the ignition needle 56 is a vertically extending long strip. Since the lower end of the ignition needle 56 is inserted into the mounting hole 5011 of the base 501 of the above-mentioned nozzle holder 50, and the upper end is inserted into the cover body 58, the long strip shape of the ignition needle 56 can effectively reduce the blocking area of ​​the air inlet of each ejection tube, thereby reducing the influence of the setting of the ignition needle 56 on the ejection performance of the burner body 5.

[0065] Furthermore, the top surface of the protective shell 560 is stepped, and the first electrode needle 561 and the second electrode needle 562 are respectively arranged on the top surface of the protective shell 560, thereby avoiding water accumulation on the top surface of the protective shell 560, thereby avoiding discharge at the root of the electrode needle caused by water accumulation.

[0066] Furthermore, the middle portion of the protective shell 560 extends outwardly in the circumferential direction to form a positioning boss 5601. When the ignition needle 56 is inserted into the base 501, the positioning boss 5601 is supported on the edge of the mounting hole 5011, so that the ignition needle 56 can be firmly inserted into the base body 531. Furthermore, the bottom of the positioning boss 5031 has a reinforcing block 5602 protruding outward 5121, so as to strengthen the strength of the ignition needle 56 and prevent the ignition needle 56 from being broken when the burner body 5 is disassembled.

[0067] In addition, the projection of each electrode needle on the horizontal plane does not exceed the maximum cross-section of the protective shell 560, so that the ignition needle 56 can smoothly pass through the positioning hole 585 on the cover 58. Further, the stove shell 1 is provided with an ion igniter (not shown) that can cooperate with the ignition needle 56, so that the burner body 5 in this embodiment does not need to be provided with a thermocouple separately, and the ion igniter and the first electrode needle 561 can play the role of the thermocouple, thereby making the structure of the burner body 5 simpler, avoiding the space below the cover 58 being cramped due to the provision of a thermocouple, thereby affecting the ejection performance of each ejection tube.
