[0065] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0066] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0068] The control valves used to supply and adjust the gas flow in existing stoves are generally equipped with protruding control parts such as manual knobs on the stove panel, which not only affects the neat appearance but also makes it difficult to clean. In addition, for the stove as a whole, the bottom of the ignition distributor is equipped with a curved pipe and connected to a larger ejector. The control valve is configured through the pipeline at the entrance of the ejector or further upstream, resulting in more space occupied by devices and pipelines, and also posing a greater safety hazard.

[0069] See also Figures 1 to 11 The present application discloses a control valve for a gas stove, which further improves the integration level and is more convenient for use in combination with an ignition distributor. The gas control principle of the control valve can utilize the existing technology, which is not the focus of improvement of the present application. This embodiment mainly improves the valve body structure and can be applied to the stoves in the following embodiments.

[0070] In this embodiment, the control valve includes a valve body 100, which has a valve cavity 130 inside. A valve core assembly 140 is installed in the valve cavity 130, and an actuator 150 is installed outside the valve body. The actuator 150 is linked with the valve core assembly to control the on-off, flow direction, and flow rate of the gas.

[0071] The specific positions of the upper, lower, top and bottom in this application can be understood by referring to the actual working posture of the stove, for example Fig.14 The direction in.

[0072] In order to facilitate adaptation with other components of the stove and improve integration, the top side of the valve body 100 is provided with an air outlet 112 connected to the valve cavity 130, and the outer periphery of the air outlet 112 is provided with a mounting portion for cooperating with a support member, such as a stove top, a fire divider, or a stove soup plate. In some embodiments below, the support member is a baffle 300 that can also serve as a soup plate, and the engaging surface of the mounting portion is arranged upward. The valve body 100 also has an air inlet 121 connected to the valve cavity 130.

[0073] The air outlet 112 is arranged on the top surface, and the air inlet 120 is arranged on the bottom. In some embodiments, the air inlet 120 is located on the bottom end surface and opens downward. In other embodiments, it can also be on the horizontal side of the valve body, that is, the side with the opening facing horizontally, which can further reduce the overall height of the valve body.

[0074] The joint surface of the mounting portion faces upward, that is, the valve body 100 is located below the support member when installed. Figure 1 It can be seen that the mounting portion is provided with a mounting hole 117, which can be fixed to the upper support member by a fastener.

[0075] In a preferred embodiment, the top of the valve body 100 is disc-shaped, and the top surface of the valve body 100 has a sedimentation area, in which an air outlet 112 connected to the valve cavity 130 is provided, and the valve body 100 has an air inlet 121 connected to the valve cavity. In this embodiment, the shape of the top of the valve body 100 is further optimized, and a sedimentation area that can accommodate airflow is constructed on the top surface.

[0076] For ease of processing, the valve body 100 can generally be designed as a split structure, for example, it can be fastened and fixed in the horizontal direction, the up and down direction, etc. For example, the valve body 100 includes a top seat 110 and a base 120 that are fixedly connected and enclosed to form a valve cavity 130, that is, it is divided into upper and lower parts, and the top seat 110 is disc-shaped as a whole and has an annular wall 111 protruding from the edge of the top surface. The top surface of the annular wall 111 is a mating surface that cooperates with the support member, and is provided with a mounting hole 117.

[0077] The annular wall 11 forms a settling area (corresponding to the isolation air chamber 400 described below) that can accommodate airflow. The top surface of the top seat 110 is provided with an air outlet 112 in the settling area that is connected to the valve cavity 130. The gas in the valve cavity 130 is output through the air outlet 112 and supplied to the ignition distributor located above. The number and position of the air outlet 112 can be configured according to the structure of the ignition distributor. In order to adjust the flow rate, a gas nozzle 113 can be installed at the air outlet 112. The base 120 also has an air inlet 121 in communication with the valve cavity 130. The air inlet 121 is used to connect to an external gas pipeline. In order to facilitate connection, the air inlet portion can be constructed as a tubular structure with an external thread 122.

[0078] The valve core assembly 140 is installed in the valve cavity 130 to control the degree of continuity between the air inlet 121 and the air outlet 112 .

[0079] The actuator 150 is installed on the valve body, for example, installed on the base 120 and linked with the valve core assembly 140. The valve core assembly 140 may include one or more valve cores, and the actuator 150 is configured accordingly. As for the actuator itself, conventional methods such as motors and electromagnets can be used and matched with corresponding control circuits and signal acquisition feedback circuits.

[0080] In the present embodiment, the top seat 110 is disc-shaped as a whole, and the ignition divider can be directly installed on it. Due to the provision of a sedimentation area, an isolation wind chamber is formed between the top seat 110 and the ignition divider, which can prevent heat from being transferred downward quickly, thereby protecting the valve body 100 and the actuator 150, etc., especially the seals, circuit components, etc., which have relatively low heat resistance and generally need to be kept away from the ignition divider. The improvement of the valve body in the present embodiment can further improve the integration, integrate part of the structure of the burner into the valve body, and also provide a basis for the flexible design and installation of the stove.

[0081] In conventional stoves, the ignition element or the heat sensing element is generally installed on the burner head or related supporting components below the ignition distributor, at least away from the valve body. An embodiment of the present application provides a control valve assembly for a gas stove with a more integrated structure as described above, including:

[0082] A valve body 100, wherein the valve body 100 has a valve cavity 130 therein, the valve body 100 has a top side and a bottom side opposite to each other, the top side has an air outlet 112 communicating with the valve cavity 130, and the valve body 100 also has an air inlet 121 communicating with the valve cavity;

[0083] The valve core assembly 140 is installed in the valve cavity 130 to control the degree of continuity between the air inlet 121 and the air outlet 112;

[0084] The ignition element 700 is fixed to the valve body 100 and protrudes from the top side of the valve body 100 .

[0085] In order to control the valve core, an actuator 150 may also be configured, and the actuator 150 is installed on the valve body 100 and linked with the valve core assembly 140;

[0086] The control valve assembly may further include:

[0087] The thermal sensing element 800 is fixed to the valve body 100 and protrudes from the top side of the valve body 100 .

[0088] The ignition element 700 can generate electric sparks to ignite the gas, and the thermal sensing element 800 can be used to detect the temperature near the cooker or the ignition distributor and control the actuator accordingly.

[0089] See also Figure 12 to Figure 23, an embodiment of the present application further provides a cooker, comprising a flame distributor 200, a baffle 300 and a control valve connected in sequence from top to bottom, wherein the flame distributor 200 and the baffle 300 are arranged at intervals and form a primary air chamber 500 with an open periphery therebetween;

[0090] An isolation air chamber 400 is formed between the baffle plate 300 and the top surface of the control valve, and the baffle plate 300 is provided with a hollow area 310 connecting the primary air chamber 500 and the isolation air chamber 400;

[0091] The ignition distributor 200 has an air supply pipe 260, and the top surface of the control valve has an air outlet 112. The air supply pipe 260 extends into the isolation air chamber 400 to receive the fuel gas from the air outlet 112, and receives the combustion-supporting air that enters the isolation air chamber 400 through the primary air chamber 500 and the hollow area 310 in sequence.

[0092] The air supply pipe 260 extends into the isolation air chamber 400 , which can be understood as the bottom end of the air supply pipe 260 extending downward to be close to the hollow area 310 in height, for example, flush with the top surface of the baffle 300 or further extending downward to be lower than the bottom surface of the baffle 300 .

[0093] In order to improve the degree of integration, the present embodiment sets the ignition divider 200 on the top surface of the control valve through the baffle 300, that is, the control valve is located closely below the ignition divider. For heat insulation, a primary air chamber 500 and an isolation air chamber 400 are sequentially arranged along the height direction and there is always an airflow passing through the hollow area 310 between the two when working. In addition, in the isolation air chamber 400, the air outlet 112 and the bottom end port of the air supply pipe 260 are aligned with each other and arranged at intervals, which can also promote airflow disturbance and inhale a part of the combustion-supporting air. These factors are conducive to the heat insulation of the control valve.

[0094] The baffle can also be used as a soup plate or a water collecting plate. In order to stabilize the combustion, the ignition distributor 200 is installed. The ignition distributor 200 is suspended above the baffle 300 through support legs arranged at intervals. The periphery of the primary air chamber 500 is an open structure except for the support legs, which is convenient for the sufficient supply of combustion-supporting air. The support legs can preferably be a three-legged structure, for example, the support legs include three support columns 320 arranged at intervals along the circumference. The bottom of the ignition distributor 200 can be configured with a connecting column 221, a positioning groove, etc. to cooperate with the top of the support column 320 in a positioning manner.

[0095] To prevent shaking, the cross-sectional area of ​​the support column or the contact area between the ignition device 200 and the support column (each) should not be greater than 70 mm 2 The smaller conduction area can limit the heat transfer from the ignition distributor to other components, so that the control valve and electrical control components can operate in a lower temperature environment.

[0096] In conjunction with the arrangement of the ignition distributor 200, see Figures 1 to 11 In the above embodiments, the control valve used includes:

[0097] The valve body 100 has a valve cavity 130 inside, and the valve body 100 has an air inlet 121 and an air outlet 112 connected to the valve cavity 130. The top edge of the valve body 100 is protruding upward with an annular wall 111 located outside the hollow area 310. The annular wall 111, the top surface of the valve body 100 and the bottom surface of the baffle 300 together form an isolation air chamber 400, wherein the top surface of the valve body 100 has a circular outer contour, and the annular wall 111 is also circular as a whole.

[0098] The valve core assembly 140 is installed in the valve cavity 130 and is used to control the degree of continuity between the air inlet 121 and the air outlet 112;

[0099] The actuator 150 is mounted on the valve body 100 and is linked to the valve core assembly 140 .

[0100] The valve body 100 includes a top seat 110 and a base 120 which are fixedly connected and enclose the valve cavity 130. The top seat 110 is generally disc-shaped and is covered below the middle area of ​​the baffle 300. The hollow area 310 is within the covering range of the top seat. That is, the top of the isolation air chamber 400 is not completely open, but only the middle part is open to the hollow area 310. Moreover, from a downward perspective, the outer edge of the ignition distributor 200 completely surrounds the hollow area 310, that is, it is located outside the hollow area 310, which can further guide the airflow direction and take into account the isolation of heat transfer downward.

[0101] For easy installation and vertical barrier-free assembly, the outer edge of the baffle 300 completely surrounds the control valve from a downward perspective. The outer edge of the top seat 110 of the control valve completely surrounds the base 120. The outer edge of the top seat 110 of the control valve also completely surrounds the housing 160.

[0102] Combined with a specific installation method, the air inlet 121 in the control valve is located on the bottom surface of the base 120, which is convenient for connecting to the gas pipeline from directly below, and the air outlet 112 is arranged on the top surface of the top seat, which is convenient for cooperating with the ignition distributor 200 directly above.

[0103] The base 120 extends vertically downward from the top seat 110, and the actuator 150 is installed on the horizontal side of the base 120. From a downward perspective, the outer edge of the top seat 110 completely surrounds the actuator 150, which is convenient for packaging.

[0104] For example, the outer peripheral cover of the control valve is provided with a housing 160, which is completely closed in the circumference (it can be understood that there is no obvious or large open or spaced area), and only the bottom surface is provided with a bypass port 161 for passing the pipeline. Of course, if the air inlet 121 is on the horizontal side, the bypass port 161 is correspondingly on the horizontal side.

[0105] The top surface of the housing 160 is an open structure, and the edge portion 162 is fixedly connected to the edge portion of the top seat 110. The base 120 and the actuator 150 are encapsulated inside, which makes the appearance neater and reduces the risk of collision when installed vertically.

[0106] The valve core assembly 140 includes:

[0107] The first valve core 141 controls the connection between the air inlet 121 and the air outlet 112;

[0108] The second valve core 142 controls the flow of each gas outlet 112;

[0109] The actuator 150 is composed of two sets, which drive the first valve core 141 and the second valve core 142 respectively.

[0110] The first valve core 141 is located upstream and controls the on-off of the gas as a whole. It can be driven by electromagnetics. For example, the power part of the actuator is specifically an electromagnet 151.

[0111] The second valve core 142 is located downstream, the second valve core 142 is cylindrical and has a plurality of air distribution holes 143 on the peripheral wall, and the power part of the actuator of the second valve core 142 is specifically a motor 152 (such as a stepping motor), and is linked to the second valve core 142 through a transmission mechanism 153 (for example, a gear set transmission).

[0112] Combination Figure 8 , Fig. 9 A sealing gasket 123 is clamped between the base 120 and the top seat 110. The top surface of the base 120 has a first outlet 124 and a second outlet 125, and the bottom surface of the top seat 110 corresponds to the first inlet 114 and the second inlet 115 respectively. The second valve core 142 rotates to different positions, which can guide the gas to output the first outlet 124 and / or the second outlet 125 and control the flow rate, and can provide multi-stage fire control (for example, 4 to 8 stages, etc.).

[0113] An embodiment of the present application also provides a control valve for a gas stove, including a valve body 100, the valve body 100 includes a top seat 110 and a base 120 fixedly connected and enclosing a valve cavity, a first thermal insulation pad is provided between the top seat 110 and the base 120, the interior of the valve body 100 is provided with a valve cavity 130, the valve body 100 has relative top and bottom sides, the top side is provided with an air outlet 112 connected to the valve cavity 130, and the valve body 100 is also provided with an air inlet 121 connected to the valve cavity.

[0114] The control valve also includes:

[0115] The valve core assembly 140 is installed in the valve cavity 130 to control the degree of continuity between the air inlet 121 and the air outlet 112;

[0116] The actuator 150 is mounted on the valve body 100 and is linked to the valve core assembly 140 .

[0117] In combination with the sealing pad 123 mentioned above, a first thermal insulation pad with better thermal insulation properties can be directly replaced in its place to slow down the heat transfer to the bottom of the valve body 100. A first thermal insulation pad can be further provided on the basis of the sealing pad 123. The thickness of the first thermal insulation pad can generally be 2 to 8 mm. For example, a 5 mm polytetrafluoroethylene pad can be used to take both sealing and thermal insulation into consideration.

[0118] Taking the double-ring fire distributor as an example, the gas enters the second inlet 115 and is distributed to different gas outlets 112 through the tubular structure 116 in the top seat 110, and all of them provide gas for the outer ring. After the gas enters the first inlet 114, it is distributed to different gas outlets 112, and all of them provide gas for the inner ring.

[0119] The tubular structure 116 and the first inlet 114 and the second inlet 115 are also understood to be a part of the valve cavity 130 and are located inside the top seat 110 , and this part is communicated with each gas outlet 112 .

[0120] In order to facilitate control, especially wireless control, the cooker is also provided with a controller 810 (for example, in the form of an integrated circuit board, etc.) electrically connected to the actuator 150, and a wireless communication module is provided in the controller. For closed-loop control, sensors 154 can be respectively configured for the electromagnet 151 and the motor 152 to detect the state or position, and the controller outputs the corresponding control signal after processing. The controller can be installed in the housing 160 directly or through a bracket, etc.

[0121] The housing 160 may also have a separate isolated chamber for accommodating the controller, and the chamber wall may be made of heat-insulating material to provide better protection.

[0122] Regarding the fire distributor, two main types of structures are provided below, such as Fig.12 The middle one is a single ring fire distributor. Fig.13 The double-ring fire divider in the figure includes an inner ring 200a and an outer ring 200b which are nested.

[0123] Combined with 14~ Fig.23 In the cooker, there are one or more air outlets. Especially when a double-ring fire distributor is used, the air outlets 112 are divided into two groups, supplying air to the inner ring 200a and the outer ring 200b respectively.

[0124] The fire distributor 200 comprises a lower seat 220 and an upper cover 210 which are buckled with each other. In the case of a double ring fire distributor, the upper cover 210a and the upper cover 210b are respectively provided inside the lower seat 220:

[0125] The first distribution chamber 230 is arranged in an annular shape. The air supply pipe 260 is connected to the bottom wall 231 of the first distribution chamber 230. A plurality of fire holes 232 are arranged along the circumferential direction on the top edge of the outer chamber wall of the first distribution chamber 230.

[0126] In the inner ring of the double-ring fire divider or the single-ring fire divider, the gas flowing out of the gas nozzle 113 is mixed with the combustion-supporting air in two independent gas supply pipes 260 perpendicular to the horizontal plane, and then enters the first distribution chamber 230, flows out from the fire hole 232, and is mixed with the combustion-supporting air again to form stable combustion.

[0127] For the double-ring fire distributor, the lower seat 220 is also provided with:

[0128] The second distribution chamber 240 is arranged in an annular shape and is located at the outer periphery of the first distribution chamber 230. The air supply pipe 260b is connected to the bottom wall 241 of the second distribution chamber 240. The top edge of the outer wall of the second distribution chamber 240 is provided with a plurality of fire holes 242 arranged along the circumferential direction.

[0129] The secondary air chamber 250 is located between the first distribution chamber 230 and the second distribution chamber 240 in the radial direction. The secondary air chamber 250 is open at the top and arranged in a ring shape. The bottom wall 251 of the secondary air chamber 250 is provided with an air hole 252 connected to the primary air chamber 500.

[0130] In the outer ring of the double-ring fire distributor, the fuel gas flowing out from the gas nozzle 113 is mixed with the combustion-supporting air in two independent gas supply pipes 260b (the inner ring corresponds to two gas supply pipes 260a) perpendicular to the horizontal plane, and then enters the second distribution chamber 240, flows out from the fire hole 242, and is mixed with the combustion-supporting air again to form stable combustion.

[0131] The combustion air of the primary air chamber 500 can be supplied to the inner ring and the outer ring through the air holes 252. The air supply pipes 260 and the air outlets 112 are arranged in at least two groups in a one-to-one correspondence, and the groups are arranged in a straight line along the first reference line 170. Figure 4 It can be seen that it corresponds to Fig.23 That is, a total of four air supply pipes 260b and 260a are arranged along the first reference line 170. The position and area of ​​the air hole 252 can be arranged according to the distance from the air supply pipe to ensure the consistency of the flame height. The method of adjusting the flame height by means of diverter plates in the prior art can be omitted, making the processing simpler.

[0132] In this embodiment, the second distribution chamber 240 is divided into at least two mutually isolated unit areas along the circumferential direction, namely, unit area 240a and unit area 240b, and each unit area is independently equipped with a gas supply pipe 260. The second distribution chamber 240 is divided into two mutually independent parts, and when one of the two gas nozzles corresponding to the outer ring is accidentally blocked, it is prevented that the combustible gas mixture flows from the unblocked end to the blocked end to produce adverse consequences.

[0133] In this embodiment, each air supply pipe 260 extends with equal diameter, and after the air supply pipe 260 extends vertically downward, the bottom port 261 corresponds to the air outlet 112. In terms of height, the air supply pipe 260 extends into the isolation air chamber 400, and the bottom port 261 is suspended above the corresponding air outlet 112, that is, there is a gap between the bottom port 261 and the gas nozzle 113.

[0134] The top outlet of each gas supply pipe has a sinking area around it, such as the sinking area 234 in the first distribution chamber 230 and the sinking area 243 in the second distribution chamber 240 .

[0135] The ignition distributor 200 of this embodiment has a circular outer contour as a whole, and the first reference line 170 is the diameter of the ignition distributor 200. The area surrounded by the first distribution chamber 230, i.e., the center of the circle, is used as the mounting hole 233 and is provided with a thermal sensing element 800 fixed to the control valve (e.g., an anti-dry-burning sensor 800b, which sends a fire-off signal when the temperature of the upper cooker is too high, and drives the first valve core 141 to cut off the gas).

[0136] The air holes 252 in the secondary air chamber 250 are distributed on both sides of the first reference line 170 .

[0137] In the single-ring fire distributor, the outer periphery of the first distribution chamber 230 is also provided with mounting holes 223 and mounting holes 224 located on one side of the first reference line, which are respectively provided with a thermal sensing element 800 (for example, a thermocouple 800b, which can send an actuator drive signal after the gas is ignited to drive the first valve core 141 to maintain the gas supply) fixed to the control valve and an ignition element 700.

[0138] In the double ring fire distributor, the bottom wall 251 in the secondary air chamber 250 is provided with mounting holes 253 and 254 located on one side of the first reference line 170, and the ignition element 700 and the thermal sensing element (such as thermocouple 800b) fixed to the control valve are respectively provided. The thermal sensing element 800 and the ignition element 700 are both connected to the controller for easy control.

[0139] In the baffle 300 , the hollow area 310 is generally strip-shaped and extends along the strip substantially along the first reference line 170 . Both ends of the hollow area 310 in the length direction extend adjacent to the inner side wall of the isolation air chamber 400 .

[0140] When the stove is working, the flow direction of combustion air is:

[0141] Entering the primary air chamber 500 from the outer periphery of the ignition distributor 200, then entering the isolation air chamber 400 through the hollow area 310, and then entering the air supply pipe 260 through the bottom port 261, these areas are connected in sequence to form a first channel for supplying combustion-supporting air to the ignition distributor;

[0142] The gas supply pipe 260 also serves as a gas passage to receive the gas from the corresponding gas outlet 112 .

[0143] In the double ring fire distributor, part of the combustion air flows as follows:

[0144] The air enters the primary air chamber 500 from the outer periphery of the ignition distributor 200, enters the secondary air chamber 250 through the air holes 252, and is then supplied between the inner ring and the outer ring. These areas are connected in sequence to form a second channel for supplying combustion-supporting air to the ignition distributor.

[0145] In order to simplify components, improve appearance and versatility, the cooker of another embodiment is only controlled by remote control. On the one hand, the actuators in the control valve are all controlled by wireless remote control, and the ignition element or other controllable components are also controlled by remote control, eliminating the control elements such as protruding knobs.

[0146] In order to ensure the heat insulation effect and optimize the airflow direction, the isolation air chamber 400 is a flat circular space, and the height of the isolation air chamber 400 is at least 0.5 cm, for example, 1 to 3 cm. The height of the primary air chamber 500 is at least 0.5 cm, for example, 0.7 to 2 cm.

[0147] In order to receive the splashes during cooking, the top surface of the baffle 300 is provided with an annular water collection groove 340 distributed around the hollow area 310. The top surface of the baffle 300 is provided with a bracket 600, and the legs 610 of the bracket 600 can be engaged with the positioning groove 350 on the top surface of the baffle 300 to prevent misalignment. As for the baffle 300 itself, the outer contour shape can be circular or rectangular.

[0148] An embodiment of the present application further provides a stove, comprising a ignition distributor 200 and a control valve for supplying gas to the ignition distributor 200, wherein the top of the control valve is disc-shaped, and the bottom of the control valve does not exceed the outer edge of the disc when viewed from a downward angle;

[0149] The bottom of the ignition distributor 200 is fixed just above the disc, and a baffle 300 is provided between the ignition distributor 200 and the control valve, the outer edge of the baffle 300 exceeds the outer edges of the ignition distributor 200 and the control valve, and a hollow area 310 is provided in the middle of the baffle 300. The specific structures and additional features of the various components of the stove of this embodiment can be combined with the various embodiments described above.

[0150] An embodiment of the present application further provides a stove, comprising a ignition distributor 200 and a control valve, wherein the top of the control valve is disc-shaped and has an air outlet 112, the ignition distributor 100 is fixed to the top of the control valve, and the ignition distributor 200 has an air supply pipe 260 arranged vertically and horizontally with the air outlet 112 and aligned with each other;

[0151] The control valve has an air inlet 121, and the bottom cover of the control valve is provided with a shell 160, and a avoidance opening 161 corresponding to the position of the air inlet 121 is provided on the bottom surface of the shell. For example, the air inlet 121 is located on the bottom surface of the control valve, and is exactly aligned with the position of the avoidance opening 161, which is more convenient for the structural design of the control valve and the arrangement of the pipelines. The specific structures and additional features of the various components of the stove of this embodiment can be combined with the various embodiments described above.

[0152] An embodiment of the present application further provides a cooker, comprising:

[0153] The baffle plate 300 has a hollow area 310 in the middle, and the edge of the baffle plate 300 is a mounting edge 330 for being embedded with the stove;

[0154] The control valve has an air inlet 121 and an air outlet 112 opposite to each other. The control valve is located directly below the baffle 300 and is spaced apart from the bottom surface of the baffle 300 to form an isolation air chamber 400. The air outlet 112 is located on the top surface of the control valve and faces the isolation air chamber 400.

[0155] The flame divider 200 is mounted above the hollow area 310 of the baffle 300, and forms a primary air chamber 500 with an open periphery between the flame divider 200 and the top surface of the baffle 300. The primary air chamber 500 is connected to the isolation air chamber 400 via the hollow area 310. An air supply pipe 260 corresponding to the position of the air outlet 112 is provided at the bottom of the flame divider 200.

[0156] Since the control valve structure is improved in the present application, the air inlet 121 of the control valve can be directly used as the gas inlet of the stove as a whole and connected to the external gas pipe. Although necessary elbows or adapter pipe joints can also be provided, at least the longer extension pipeline can be omitted, thereby reducing interference and gas leakage points inside the stove and reducing gas pressure loss.

[0157] From the external gas pipe to the gas output, the non-integrated connection points in the stove can be reduced to only three, including the connection part between the external gas pipeline and the air inlet 121, the joint part between the top seat 110 and the base 120 in the valve body, and the connection part between the air outlet 112 and the gas nozzle 113. Compared with the existing stoves, the number of connection points is greatly reduced, which can improve safety, further simplify the structure and reduce costs.

[0158] The specific structures and additional features of the various components of the stove of this embodiment can be combined with the previous embodiments.

[0159] Based on the control valve and stove of the above embodiment, the present application also provides a kitchen stove system, which can be seen in Fig.12 , specifically including:

[0160] A stove top 900 is pre-installed in the kitchen, and a mounting opening 910 is provided on the stove top 900;

[0161] The edge of the baffle 300 of the stove is overlapped and fixed on the stove table 900, and the control valve is sunk under the stove table 900 through the installation port 910.

[0162] The top and horizontal sides of the stove top 900 and the area adjacent to the stove are all smooth structures, that is, there are no protruding control parts such as manual valves, and the stove can be used by remote control, such as a remote control, or controlled by a mobile phone, or by voice control.

[0163] See also Figure 24 to Figure 36 In another embodiment of the present application, a single-ring fire distributor is used. The control valve can adopt the above embodiments, for example, including a valve body with a valve cavity 130 inside, a valve core assembly is installed in the valve cavity 130, an actuator 150 is installed outside the valve body, the actuator 150 is linked with the valve core assembly to control the gas, and the valve body includes a top seat 110 and a base 120 fixedly connected and enclosing to form a valve cavity.

[0164] In this embodiment, in order to take into account both heat insulation and sealing, a first heat insulation pad 126 is provided between the top seat 110 and the base 120. The thickness of the first heat insulation pad 126 can generally be 2 to 8 mm. For example, a 5 mm polytetrafluoroethylene pad is used, and a sealing pad 123a and a sealing pad 123b can be provided on the upper and lower sides of the first heat insulation pad 126, respectively.

[0165] The top side of the top seat 110 is provided with an air outlet 112 communicating with the valve cavity 130, and the horizontal side of the base 120 is provided with an air inlet 121 communicating with the valve cavity. A gas nozzle 113 is installed at the air outlet 112, and the top seat 110 is also provided with a thermal sensing element 800 and an ignition element 700, or at least provides an installation position or an avoidance area, for example, an anti-dry burning sensor is provided as needed, and the figure shows a mounting seat 820 of the anti-dry burning sensor.

[0166] Since only one ring is supplied with gas, the top surface of the base 120 can use only the second outlet 125, and the bottom surface of the top seat 110 is correspondingly configured with the second inlet 115, and the remaining outlets or inlets can be omitted or adapted to the internal connection mode.

[0167] The outer peripheral cover at the bottom of the control valve is provided with a shell 160, which is a cylindrical shape with an open top surface and a plurality of heat dissipation holes 163 on the shell wall to prevent excessive temperature inside the shell 160. The edge portion 162 at the top of the shell 160 is fixedly connected to the edge portion of the top seat 110.

[0168] Part or all of the periphery of the top seat 110 is exposed to the housing 160, and the exposed part has a mounting portion for matching with a support member, such as a stove, a bracket, etc. In this embodiment, the mounting portion is at least two coupling grooves 118 arranged at intervals along the circumference, such as three or four coupling grooves 118 evenly arranged along the circumference. The support member can extend into the coupling groove 118 from different angles, and the extended portion is fixed by a clamping member 119. The mounting portion can also be in other forms, but it is preferably not protruding from the outer circumferential surface of the valve body to avoid assembly interference.

[0169] The bottom of the housing 160 is provided with a separate isolated chamber for accommodating the controller 810 to provide better protection and heat insulation. To facilitate the installation of the controller 810, the bottom of the housing 160 is a detachable bottom plate 164, which together with the partition plate 165 fixed inside the housing 160 forms a chamber for accommodating the controller 810. To enhance heat insulation, a second heat insulation pad 127 can be fixed on the bottom surface of the top seat 110. In addition to the necessary avoidance area, the second heat insulation pad 127 covers all areas of the bottom surface of the top seat 110 as much as possible. Figures 37 to 49 In another embodiment of the present application, a double ring fire distributor is used. Regarding the control valve part, the same Fig.24 The structure is similar to that in FIG. 1 , but the main difference is that there are four gas outlets 112, which are used to provide fuel gas to the inner ring 200a and the outer ring 200b respectively.

[0170] Based on the control valve and stove of the above embodiments, the present application also provides an assembly method of a kitchen stove system, comprising:

[0171] A stove is provided, the top of which is a stove table 900. The stove can be fixedly pre-installed in the kitchen or configured in a movable manner. The stove table 900 is provided with an installation opening 910; the installation opening 910 can be closed at the periphery or partially open, and the size can at least accommodate the base of the valve body.

[0172] A stove is provided, comprising the control valve of each embodiment described above and a ignition divider connected to the top of the control valve. The stove is placed into the mounting opening from the upper side of the mounting opening 910, so that at least a portion of the control valve is sunk below the top surface of the mounting opening. For example, the air inlet is below the stove top 900, which is convenient for docking with the gas pipeline, and at least a portion of the ignition divider is above the top surface of the mounting opening; operations below the stove top 900 can be reduced, thereby improving assembly efficiency.

[0173] When fixing the stove to the stove, the baffle 300 whose outer edge is larger than the size of the installation opening can be directly overlapped on the stove top, and the baffle and the stove top can be further fixed by connecting parts or gluing. When fixing the stove to the stove, a support member fixed to the stove can also be used, and the support member is fixed to the valve body through the coupling groove.

[0174] Compared with existing conventional stoves, the stove's own panel and control components are omitted, and a mounting port 910 can be flexibly opened on the pre-installed stove countertop 900 to configure a corresponding number of stoves. During installation, the shell 160 at the bottom of the control valve can be directly inserted vertically downward through the mounting port 910, and the bottom surface of the baffle 300 is fitted and fixed to the top side of the stove countertop 900. As far as a single stove is concerned, the stove area occupied by it is greatly reduced, and the neatness and integration are significantly improved.

[0175] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0176] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
