[0002] With the continuous development of the economy, people's living standards are also constantly improving, and the quality of life requirements are getting higher and higher. The kitchen is one of the most important places in the home. Having a multifunctional and clean kitchen can make the whole family feel warm. For this reason, an integrated stove that integrates multiple functions such as range hoods, gas stoves, and disinfection cabinets has emerged. However, the cleaning problem of gas stoves has not been solved. For this reason, a Chinese utility model patent number ZL201621298462.7 (authorization announcement number CN206233318U) "An integrated stove" discloses an integrated stove with a stove, a middle sink, and a cutting board. An integrated stove with a sink, wherein the stove includes a sink, the bottom of which is provided with a sewage channel, the sink includes a first step and a second step, a pot bracket supporting the pot body is movably fixed on the first step, and an ignition switch is provided on the second step. After the stove is used, the pot bracket can be removed, and then the second movable faucet can be rotated to the top of the stove, the second movable faucet can be pulled out to the inside of the stove and the inside of the stove can be cleaned. The stove is cleaned with the faucet, and the clean water in the stove quickly flows into the sink through the inclined bottom of the middle sink, but the clean water can easily wet or dirty the burner in the process of flowing into the sink.

[0003] Or a Chinese utility model patent number 201520165593.7 (authorization announcement number CN204593498U) "A stove panel and stove" discloses a stove panel, including a panel body and a water collection tank recessed downward by the top surface of the panel body, the top surface of the panel body is recessed downward to form a drainage slope intersecting with the bottom surface of the water collection tank, the drainage slope is used to guide the liquid in the water collection tank to drain, the stove panel of the utility model is improved on the basis of the existing stove panel, the original horizontal top surface of the stove panel is designed to be inclined to form a new recessed The drain slope of the new recessed area intersects with the bottom surface of the sump, connecting the sump with the new recessed area, making it convenient for the water in the sump to flow out for cleaning. Although the above two solutions, whether it is an integrated stove or an improvement of the stove panel with a method of guiding cleaning water to the sump, are only suitable for cleaning the stove after use, neither of them takes corresponding precautions on the stove burner before cooking food to prevent oil stains from entering the burner, thereby causing inconvenience in subsequent cleaning; in addition, the above two solutions are not very effective in cleaning oil stains splashed onto the stove panel. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide an anti-fouling structure for a gas stove burner in response to the above-mentioned existing technical status, which can effectively prevent overflow during cooking or cleaning water after cooking from affecting the burner.

[0005] The second technical problem to be solved by the present invention is to effectively prevent the oil spilled during the cooking process from contaminating the stove panel with the gas stove having the anti-fouling structure.

[0006] The third technical problem to be solved by the present invention is to provide a gas stove with the anti-fouling structure applied thereto, which can effectively prevent the heat of the pot support from being transferred to the stove panel during the cooking process, in response to the above-mentioned existing technical status.

[0007] The fourth technical problem to be solved by the present invention is to provide a gas stove with the anti-fouling structure, which can facilitate the discharge of cleaning water used to clean the stove panel, in response to the above-mentioned existing technical status.

[0008] The fifth technical problem to be solved by the present invention is to provide an integrated stove with the anti-fouling structure, which can clean the stove panel directly by flushing with water, in response to the above-mentioned existing technical status.

[0009] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: the anti-fouling structure for a gas stove burner is characterized in that it includes a lower guide plate, the lower guide plate has a ring-shaped plate body, the inner edge of the plate body is surrounded by a central hole for the top of the burner to pass through, and the outer periphery of the plate body has a vertical portion extending downward, covering the part of the burner located below the inner edge.

[0010] Preferably, the lower end of the vertical portion has a bell-mouth portion, which can better block overflow during cooking or clean water after cooking from outside the vertical portion.

[0011] In order to solve the second technical problem, the present invention provides a gas stove having the above-mentioned anti-fouling structure, which is characterized by comprising:

[0012] a panel having a mounting hole aligned with the central hole;

[0013] At least a portion of the vertical portion of the lower deflector is located below the panel. Liquid overflowing during cooking, if flowing into the mounting hole, is blocked by the vertical portion of the lower deflector. This prevents the burner from being affected by overflow, such as the base and ejector tube, below the inner edge of the burner. Furthermore, the use of clean water after cooking does not affect the burner.

[0014] Furthermore, an upper drip pan is included, positioned above the panel and partially covering the periphery of the mounting hole. An opening is formed between the panel and the upper drip pan for draining clean water below the mounting hole. The upper drip pan has the following functions: first, it can partially contain any overflowing liquid, preventing it from flowing into the mounting hole; and second, it can support the pot support, which is positioned above the upper drip pan and separated from the panel. This also prevents heat from the pot support from transferring to the panel during cooking, thereby reducing heat loss.

[0015] Better yet, in order to realize that the lower guide plate also has the function of holding overflow liquid or cleaning water, the lower guide plate passes through the mounting hole and can move in the vertical direction relative to the upper liquid holding plate, so that the vertical part of the lower guide plate can at least partially block the opening.

[0016] From the perspective of structural simplicity, the vertical portion has a first convex edge extending outward, and the first convex edge constitutes the bell-mouth portion.

[0017] In order to facilitate the movement of the lower guide plate relative to the upper liquid receiving plate, a driving mechanism is also included, which is located under the panel and drives the lower guide plate to move relative to the upper liquid receiving plate.

[0018] The drive mechanism includes a first electromagnetic plate and a second electromagnetic plate that repel each other, and an elastic member connected between the first and second electromagnetic plates. The first electromagnetic plate is located below the panel, and the elastic member causes the second electromagnetic plate to always tend to move toward the first electromagnetic plate. The first flange is connected to the second electromagnetic plate. During the movement of the lower guide plate relative to the upper liquid receiving plate, the following coordination conditions are achieved:

[0019] Uncooked state: The lower guide plate and the upper liquid tray are against each other, the first electromagnetic plate and the second electromagnetic plate are powered off, and the elastic member is in a natural state to prevent dust and debris from falling into the opening;

[0020] Cooking state: When the first electromagnetic plate and the second electromagnetic plate are energized, the first electromagnetic plate and the second electromagnetic plate repel each other, and the second electromagnetic plate drives the lower guide plate to move downward until it is flush with the panel. At this time, the elastic member is in a stretched state, and clean water can be stored on the lower guide plate and the panel. Therefore, during the cooking process, oil droplets can drip onto the clean water instead of directly sticking to the panel.

[0021] Cooking end state: the first electromagnetic plate and the second electromagnetic plate continue to be energized, the first electromagnetic plate and the second electromagnetic plate continue to repel each other, the second electromagnetic plate continues to drive the lower guide plate downward to under the panel, the opening is opened, and the elastic member is in a fully stretched state.

[0022] Furthermore, in order for the lower guide plate to also have the function of storing overflow or cleaning water, the second end of the plate body adjacent to the center of the mounting hole has a second annular protrusion extending upward, and the second annular protrusion and the plate body together constitute a water holding area for holding cleaning water.

[0023] Preferably, the upper liquid receiving tray comprises an upper plate having a central portion having an upwardly concave groove, into which the second annular convex wall extends. The groove design of the upper liquid receiving tray allows the upper plate to contain overflow liquid. Furthermore, the second annular convex wall of the lower guide tray extends into the groove of the upper liquid receiving tray, thereby ensuring an optimal seal between the lower guide tray and the upper liquid receiving tray when they abut against each other before cooking.

[0024] To address the third technical problem, the present invention comprises a pot holder positioned on a first outer peripheral edge of the groove, adjacent to the periphery of the mounting hole, within the upper plate. When cooking, the first and second electromagnetic plates are energized, repelling each other. The second electromagnetic plate then drives the lower deflector plate downward until it is flush with the cooking surface. The elastic member is now stretched, and clean water can be stored on the lower deflector plate and the cooking surface, creating a uniform film of water covering the cooking surface. Even if oil splashes during cooking, it floats above the clean water, preventing it from contacting the cooking surface. The pot holder, positioned on the upper plate and separated from the cooking surface, also prevents heat from the pot holder from transferring to the cooking surface during cooking, thereby reducing heat loss.

[0025] In order to increase the sealing performance when the upper liquid collecting pan and the lower guide pan abut against each other, a second convex edge is provided under the first outer peripheral edge, and the second convex edge gradually approaches the periphery of the mounting hole from top to bottom. The part of the pan body corresponding to the second convex edge is partially tilted upward, and when the pan body moves relative to the upper liquid collecting pan to the state of the second convex edge, it completely covers the opening.

[0026] In order to solve the fourth technical problem, the present invention also includes a bottom shell adapted to the panel and a burner passing through the mounting hole and the central hole, the burner includes a base, and the upper liquid tray surrounds the part of the burner located above the panel and is supported on the panel through the base to form the opening between the burner and the panel.

[0027] In order to allow the cleaning water to flow from the panel to the opening more quickly after cooking, the outer edge of the panel gradually slopes downward toward the central area, the mounting hole is located in the central area, and the burner is placed on the central area. The second outer edge of the upper plate body adjacent to the center of the mounting hole in the groove surrounds the portion of the burner located on the panel.

[0028] In order to prevent cleaning water from entering the bottom shell under the panel from the opening and affecting the electronic control part of the gas stove, the bottom shell is provided with an electronic control part for controlling the combustion condition of the burner. The bottom shell includes a vertical wall panel, which separates the bottom shell into a first cavity and a second cavity that are independent of each other. The electronic control part is accommodated in the first cavity, the burner is accommodated in the second cavity, and the opening is connected to the second cavity.

[0029] To address the fifth technical problem, the present invention provides an integrated cooker incorporating the aforementioned gas stove. The cooker is characterized by including a cleaning trough positioned alongside the stove, the cleaning trough being equipped with a flushing mechanism for flushing the panel, and a drain port on the bottom shell communicating with the cleaning trough for discharging clean water. The integrated design of the gas stove and cleaning trough facilitates water washing of the stove panel. Furthermore, cooking steps such as washing vegetables, cooking, adding water, and washing pots can be completed in the same location, reducing movement during cooking and enhancing convenience.

[0030] Compared with the prior art, the advantage of the present invention is that it provides a lower deflector plate with an anti-fouling structure, the central hole of the lower deflector plate is for the burner top to pass through and then be installed, and the vertical part of the plate body can block the overflow or cleaning water, thereby reducing the overflow or cleaning water entering the burner; in addition, the present invention also provides a gas stove with the above-mentioned anti-fouling structure, the panel of the gas stove uses a compound liquid tray composed of an upper liquid tray and a lower deflector plate to achieve the "dust-proof" effect of the gas stove in the non-cooking state, the "cleaning liquid storage" effect in the cooking state, and the "cleaning liquid drainage" effect in the cooking state. In the non-cooking state, the lower deflector plate is against the upper liquid tray, and the opening is blocked by the lower deflector plate. To prevent dust, debris, etc. from falling into the opening; in the cooking state, the lower guide plate moves downward to be level with the panel, and clean water can be stored on the lower guide plate and the panel. Therefore, oil droplets in the cooking process can drip onto the clean water instead of directly sticking to the panel; when cooking is finished, the lower guide plate moves downward to under the panel, the opening is opened, and the clean water is discharged to under the panel through the opening, so that the panel does not need to spend more time and energy to clean; in addition, the present invention also provides a gas stove using the above-mentioned panel and an integrated stove using the above-mentioned gas stove, so that cooking steps such as washing vegetables, frying vegetables, adding water, and washing pots can be completed in the same position, reducing walking during cooking and making it more convenient to use.

[0039] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0040] like Figures 1 to 8 The figure shows the best embodiment of the present invention. The anti-fouling structure for a gas stove burner in this embodiment includes a lower deflector plate 7 having an annular disc-shaped disc body 71. The inner edge 710 of the disc body 71 defines a central hole 70 for the top of the burner 3 to pass through. The outer periphery of the disc body 71 has a downwardly extending vertical portion 711, which covers the portion of the burner 3 located below the inner edge 710. Preferably, the lower end of the vertical portion 711 has a bell-mouth portion. To simplify the structure, the vertical portion 711 has a first flange 712 extending outward. The first flange 712 forms a bell-mouth portion, which can better block spillage during cooking or clean water after cooking from outside the vertical portion 711.

[0041] In addition, the present invention further provides a gas stove incorporating the above-described anti-fouling structure. The gas stove includes a panel 5 having a mounting hole 51, an upper liquid pan 6 positioned above the panel 5 and partially covering the mounting hole 51, and an opening 8 formed between the upper liquid pan 6 and the panel 5 for draining clean water below the mounting hole 51. A lower deflector 7 has at least a portion of its vertical portion 711 positioned below the panel 5. Liquid overflowing during cooking, once flowing into the mounting hole, is blocked outside the vertical portion by the vertical portion 711 of the lower deflector 7. This prevents the burner 3 from being affected by the overflow, such as the base 31 and the ejector tube, from being affected by the overflow. Furthermore, clean water after cooking does not affect the burner 3. This embodiment preferably further includes an upper liquid pan 6 positioned above the panel 5 and partially covering the periphery of the mounting hole 51, with an opening 8 formed between the upper liquid pan 6 and the panel 5 for draining clean water below the mounting hole. The upper liquid receiving pan 6 has the following functions: First, it can hold a portion of any overflowing liquid, preventing it from flowing entirely into the mounting hole 51. Second, the upper liquid receiving pan 8 can support the pot holder 10, allowing the pot holder 10 to be positioned above the upper liquid receiving pan 6 and separated from the panel 5. This prevents heat from the pot holder 10 from transferring to the panel during cooking, reducing heat loss. To ensure that the lower deflector pan 7 also serves as a container for overflowing liquid or cleaning water, the lower deflector pan 7 extends through the mounting hole 71 and can move vertically relative to the upper liquid receiving pan 6, such that the vertical portion 711 of the lower deflector pan 7 can at least partially block the opening 8. A driving mechanism 9 located on the lower surface of the panel 5 can further facilitate movement of the lower deflector pan 7 relative to the upper liquid receiving pan 6.

[0042] The panel 5 utilizes a compound liquid tray consisting of an upper liquid tray 6 and a lower guide tray 7 to achieve the "dust-proof" effect of the gas stove in the non-cooking state, the "cleaning liquid storage" effect in the cooking state, and the "cleaning liquid drainage" effect in the cooking end state. In the non-cooking state, the lower guide tray 7 is against the upper liquid tray 6, and the opening 8 is blocked by the lower guide tray 7 to prevent dust, debris, etc. from falling into the opening 8; in the cooking state, the lower guide tray 7 moves downward to be level with the panel 5, and the lower guide tray 7 and the panel 5 can store cleaning water. Therefore, oil droplets in the cooking process can drip onto the cleaning water without directly sticking to the panel 5; when cooking is finished, the lower guide tray 7 moves downward to under the panel 5, the opening 8 is opened, and the cleaning water is discharged to under the panel 5 through the opening 8, so that the panel 5 does not need to spend more time and energy to clean. The drive mechanism 9 includes a first electromagnetic plate 91, a second electromagnetic plate 92, and an elastic member 93 connected between the first electromagnetic plate 91 and the second electromagnetic plate 92, which can repel each other. The first electromagnetic plate 91 is arranged below the panel 5. The elastic member 93 makes the second electromagnetic plate 92 always have a tendency to approach the first electromagnetic plate 91. The first flange 712 is connected to the second electromagnetic plate 92. When the lower guide plate 7 moves relative to the upper liquid receiving plate 6, the following cooperative state is achieved:

[0043] Uncooked state: the lower guide plate 7 is against the upper liquid tray 6, the first electromagnetic plate 91 and the second electromagnetic plate 92 are powered off, and the elastic member 93 is in a natural state to prevent dust, debris, etc. from falling into the opening 8 (such as Figure 4 shown);

[0044] Cooking state: After the first electromagnetic plate 91 and the second electromagnetic plate 92 are energized, the first electromagnetic plate 91 and the second electromagnetic plate 92 repel each other, and the second electromagnetic plate 92 drives the lower guide plate 7 to move downward to be level with the panel 5. At this time, the elastic member 93 is in a stretched state, and clean water can be stored on the lower guide plate 7 and the panel 5. Therefore, during the cooking process, oil droplets can drip onto the clean water instead of directly sticking to the panel 5. Figure 6 As shown, the arrows in the figure indicate the path of clean water);

[0045] Cooking end state: the first electromagnetic plate 91 and the second electromagnetic plate 92 continue to be energized, the first electromagnetic plate 91 and the second electromagnetic plate 92 continue to repel each other, the second electromagnetic plate 92 continues to drive the lower guide plate 7 downward to below the panel 5, the opening 8 is opened, and the elastic member 93 is in a fully stretched state (such as Figure 8 As shown, the arrows in the figure indicate the path of clean water).

[0046] In addition, in order to ensure that the lower guide plate 7 also has the function of storing clean water, the inner edge 710 of the plate body 71 adjacent to the center of the mounting hole 51 has an upwardly extending second annular convex wall 713, and the second annular convex wall 713 and the plate body 71 together constitute a water holding area for holding clean water. Similarly, in order to realize that the upper liquid holding plate 6 also has the function of holding overflow liquid flowing down during the cooking process, the upper liquid holding plate 6 includes an upper plate body 61, and the central part of the upper plate body 61 has a groove 611 concave from bottom to top. On the other hand, the second annular convex wall 713 can also extend into the groove 611. Since the second annular convex wall 713 of the lower guide plate 7 extends into the groove 611 of the upper liquid holding plate 6, when the lower guide plate 7 and the upper liquid holding plate 6 are against each other in the non-cooking state, the sealing between the two is in a better state. A pot holder 10 is also placed on the first outer peripheral edge 612 of the upper plate body 61 near the periphery of the mounting hole 51 of the groove 611. When in the cooking state, the first electromagnetic plate 91 and the second electromagnetic plate 92 are energized to repel each other, and the second electromagnetic plate 92 drives the lower guide plate 7 to move downward to be level with the panel 5. At this time, the elastic member 93 is in a stretched state, and clean water can be stored on the lower guide plate 7 and the panel 5. A layer of water film can be evenly covered on the panel 5. Even if oil splashes during cooking, it floats above the clean water to prevent contact with the panel 5. At the same time, the pot holder 10 is located on the upper plate body 61 and separated from the panel 5. It can also prevent the heat of the pot holder 10 from being transferred to the panel 5 during cooking, thereby reducing heat loss. In order to increase the sealing performance when the upper liquid collecting pan 6 and the lower guide pan 7 abut against each other, a second flange 6121 is provided under the first outer peripheral edge 612. The second flange 6121 gradually approaches the periphery of the mounting hole 51 from top to bottom. The portion of the pan body 71 corresponding to the second flange 6121 is partially tilted upward, and when the pan body 71 moves relative to the upper liquid collecting pan 6 to the state of the second flange 6121, it completely blocks the opening 8.

[0047] The gas stove of the present invention uses the anti-fouling structure as described above, including a bottom shell 4 adapted to the panel 5 and a burner 3 arranged in the mounting hole 51, the burner 3 includes a base 31, and the upper liquid tray 6 surrounds the portion of the burner 3 above the panel 5, and is supported on the panel 5 through the base 31 to form an opening 8 between the panel 5 and the upper liquid tray 6. In order to allow cleaning water to flow from the panel 5 to the opening 8 faster after cooking is completed, the outer edge of the panel 5 gradually tilts downward toward the central area, the mounting hole 51 is located in the central area, and the burner 3 is placed on the central area. The second outer peripheral edge 613 of the upper plate body 61 near the center of the mounting hole 51 in the groove 611 surrounds the burner 3. In order to prevent cleaning water from entering the bottom shell 4 under the panel 5 from the opening 8 and affecting the electronic control part 20 of the gas stove, the bottom shell 4 is provided with an electronic control part 20 for controlling the combustion condition of the burner 3. The bottom shell 4 includes a vertical wall panel 30, which separates the bottom shell 4 into a first cavity 41 and a second cavity 42 that are independent of each other. The electronic control part 20 is accommodated in the first cavity, the burner 3 is accommodated in the second cavity 42, and the opening 8 is connected to the second cavity 42.

[0048] The present invention also provides an integrated cooker using the above-mentioned gas stove, including a cleaning tank 40 arranged side by side with the gas stove. The cleaning tank 40 is provided with a flushing mechanism 50 that can flush the panel 5. The bottom shell 4 is provided with an outlet 43 connected to the cleaning tank 40 for discharging cleaning water. Since the gas stove and the cleaning tank 40 are designed as an integrated whole, it is possible to wash the gas stove with water, which is convenient for flushing the panel 5 of the gas stove. In addition, cooking steps such as washing vegetables, cooking, adding water, and washing pots can be completed in the same location, which reduces walking during cooking and is more convenient to use.
