Description

Technical Field

[0001] The present invention relates to the field of cooking devices, and in particular to a self-cleaning cooking device. Background Art

[0002] After cooking, cooking appliances such as steamers and ovens will leave grease, food residue, and other dirt inside their inner pots, which are usually cleaned manually with a rag. However, manual cleaning is not only cumbersome and affects the user experience, but also has poor cleaning effects. To this end, the Chinese invention patent with application number CN 202110119222.5 (publication number CN112773201 A) discloses a self-cleaning cooking liner structure and cooking equipment, which includes a steam jet sleeve and a high-pressure steam chamber. The steam jet sleeve and the high-pressure steam chamber can move relative to each other and have at least two states. In the second state, the high-pressure steam chamber forms a closed cavity, and the steam pressure inside it increases. As steam enters from the steam inlet, the steam pressure in the high-pressure steam chamber becomes higher and higher. When the steam pressure in the high-pressure steam chamber reaches a certain value, the steam jet sleeve and the high-pressure steam chamber can move relative to each other, from the second state to the first state, and the high-temperature and high-pressure steam in the high-pressure steam chamber can be quickly sprayed from the steam injection hole to the inner surface of the liner, thereby softening and impacting the stains attached to the inner surface of the liner, and flushing them through the injection of high-pressure steam.

[0003] Compared with the traditional manual cleaning method, the above patent realizes automatic cleaning of the inner tank. However, the patent has a dead angle of steam injection, which affects the cleaning effect of the inner tank. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a self-cleaning cooking device with good cleaning effect inside the inner pot in view of the existing technology.

[0005] The second technical problem to be solved by the present invention is to provide a self-cleaning cooking device with good cleaning effect on the inside of the inner pot and capable of simultaneously cleaning the cooking plate in response to the existing technology.

[0006] The present invention solves at least one of the above technical problems by adopting a technical solution: a self-cleaning cooking device, comprising an inner pot with a front opening, characterized in that it also includes:

[0007] A spray head is provided on the side wall of the inner container and is used for spraying and washing the interior of the inner container;

[0008] an adjusting mechanism for rotating the nozzle to adjust the spray angle of the nozzle, comprising a first adjusting member driven by water pressure and a second adjusting member connected to the nozzle;

[0009] a first fluid channel for high-pressure water to flow, wherein the water inlet port is in fluid communication with the high-pressure water source, and the water outlet port is in fluid communication with the water inlet of the nozzle;

[0010] Furthermore, when water flows through the first fluid channel, the high-pressure water in the first fluid channel drives the first adjusting member, which causes the second adjusting member to drive the nozzle to rotate.

[0011] Furthermore, there are two nozzles, one on each of the left and right side walls of the inner container. The nozzles are positioned opposite each other and are located in the middle of the respective side walls along the front-to-back direction. The aforementioned adjustment mechanism and first fluid passage are two, each corresponding to the nozzles on the left and right sides. By providing nozzles on the left and right sides of the inner container and configuring each nozzle with a first fluid passage and adjustment mechanism, the spray angles of the nozzles on both sides can be adjusted to better avoid blind spots, thereby ensuring a better cleaning effect.

[0012] Furthermore, each of the nozzles is in the shape of an elongated strip and is disposed in the corresponding side wall along the left-right direction, and each of the nozzles can rotate up and down around a first axis extending forward and backward. In this way, the spray angle of each nozzle can be adjusted by rotating the nozzles up and down.

[0013] Furthermore, each nozzle is cylindrical in shape and has a flow channel extending along its axis. One end of the flow channel is the water inlet and the other end is the water outlet. A guide groove extending forward and backward is recessed on the end surface of each nozzle where the water outlet is located. Each guide groove is in the shape of an elongated strip, and each water outlet is located at the center of the corresponding guide groove along its own length. The cross-sectional size of each guide groove increases outward from the water outlet. The guide groove on each nozzle can guide the high-pressure water flow ejected from each water outlet in the forward and backward direction, forming a fan-shaped water curtain along the forward and backward direction. Combined with the up and down rotation of each nozzle, the high-pressure water can be fully sprayed to various locations within the inner tank.

[0014] Furthermore, the first fluid channel extends up and down, the first adjusting member is a water wheel and the second adjusting member is a connecting rod, wherein the water wheel is installed in the sealed first installation chamber and includes a wheel body, a wheel shaft and wings, wherein the wheel shaft extends horizontally and passes through the center hole of the wheel body, and the wings are arranged circumferentially on the wheel surface of the wheel body, one end of the connecting rod is pivotally connected to the disk surface of the wheel body and the other end is pivotally connected to the nozzle.

[0015] Furthermore, one side of the first installation chamber is connected to the first fluid channel, and at least one wing of the water wheel extends into the first fluid channel through the connection between the first installation chamber and the first fluid channel and is horizontally placed in the first fluid channel. During the rotation of the water wheel, at least one wing is always horizontally placed in the first fluid channel.

[0016] When water flows through the first fluid channel, the water flowing toward the nozzle impacts the wings in the first fluid channel, driving the hydraulic impeller to rotate. The rotating hydraulic impeller then drives the nozzle through the connecting rod. This way, as the high-pressure water in the first fluid channel flows toward the nozzle, it drives the hydraulic impeller to rotate, which in turn drives the nozzle through the connecting rod, adjusting the nozzle's spray angle.

[0017] Furthermore, a cooking plate for placing food is horizontally arranged in the inner pot below the nozzle in the left-right direction, and the bottom of the cooking plate is connected to a rotating shaft passing through the inner pot in the left-right direction.

[0018] It also includes a driving mechanism for driving the rotating shaft to rotate around its own axis. The driving mechanisms are respectively arranged on the left and right sides of the inner container and correspond to the first fluid channels one by one. Each driving mechanism includes a driving member and a transmission member.

[0019] Each of the first fluid channels extends vertically. After cooking is complete, high-pressure water is simultaneously introduced into the left and right first fluid channels. The high-pressure water flowing toward the corresponding nozzle in each first fluid channel drives a corresponding drive member, which in turn drives a corresponding transmission member to rotate the rotating shaft. After cooking is complete, not only will oil stains and other dirt remain on the inner surface of the cooking plate, but dirt and other dirt will also remain on the outer surface of the cooking plate, making it difficult to clean. By flipping the cooking plate upside down, the high-pressure water sprayed from each nozzle can thoroughly clean the inner and outer surfaces of the cooking plate. This allows the present invention to simultaneously self-clean the interior of the inner pot and the outer and inner surfaces of the cooking plate. Furthermore, the high-pressure water in each first fluid channel drives the rotation of the cooking plate via each drive mechanism, enabling the high-pressure water spraying from each nozzle and the rotation of the cooking plate to occur simultaneously.

[0020] Furthermore, each of the driving members is a water-dynamic gear, and each transmission member is a transmission gear that can mesh with the corresponding water-dynamic gear, and each water-dynamic gear is respectively installed in a second installation chamber, one side of the second installation chamber is open and connected to the corresponding first fluid channel, and the other side is also open for each water-dynamic gear to mesh with the corresponding transmission gear, at least one tooth of the water-dynamic gear extends into the first fluid channel through the connection between the second installation chamber and the first fluid channel and is horizontally placed in the first fluid channel, and during the rotation of the water-dynamic gear, at least one tooth is always horizontally placed in the first fluid channel.

[0021] Furthermore, each second mounting chamber and its corresponding transmission gear are located within a sealed third mounting chamber. Both ends of the rotating shaft extend into the corresponding third mounting chamber and connect to the center of the corresponding third transmission gear. As high-pressure water in each first fluid channel flows toward the corresponding nozzle, it drives the corresponding hydraulic gear to rotate. The rotating hydraulic gears then drive the corresponding transmission gear to rotate in the same direction, ultimately driving the rotating shaft to achieve the up and down rotation of the cooking plate.

[0022] Furthermore, the system includes a water inlet tank and a high-pressure jet pump. The water outlet of the water inlet tank is in fluid communication with the water inlet interface of the high-pressure jet pump, while the first and second water outlet interfaces of the high-pressure jet pump are in fluid communication with the water inlet ports of each first fluid channel. After water in the water inlet tank enters the high-pressure jet pump, it is formed into high-pressure jets on the left and right sides of the high-pressure jet pump, and the resulting high-pressure water is respectively passed into each first fluid channel.

[0023] Furthermore, a wastewater outlet is provided on the bottom wall of the inner container, which is in fluid communication with the return water connection of the high-pressure jet pump. A filter is provided between the wastewater outlet and the return water connection, so that the wastewater after cleaning is filtered by the filter and then flows back into the high-pressure jet pump. This allows the cleaning wastewater to be recycled, saving water resources and reducing cleaning costs.

[0024] Furthermore, the high-pressure jet pump is located under the inner tank, and the wastewater outlet and the return water interface are connected through a vertically extending return water channel. The filter includes a filter screen that is separated from the return water channel. A vertically extending vertical rod is fixed to the filter screen, and a baffle is fixed to the top of the vertical rod. The baffle is located directly above the wastewater outlet and has a vertical gap between it and the wastewater outlet. The filter screen can intercept particles, oil, etc. in the backflow of cleaning wastewater, and the baffle can prevent the high-pressure jet from spraying into the wastewater outlet.

[0025] Compared with the prior art, the present invention has the following advantages: when cooking is complete, water flows through the first fluid channel, and the high-pressure water in the first fluid channel is ejected through the nozzle to perform high-pressure water cleaning on the interior of the inner pot, achieving self-cleaning of the inner pot. Furthermore, an adjustment mechanism is provided, which includes a first adjustment member and a second adjustment member. The high-pressure water in the first fluid channel drives the first adjustment member, which in turn causes the second adjustment member to rotate the nozzle, thereby adjusting the nozzle's spray angle, avoiding blind spots, and ensuring a thorough cleaning of the inner pot.

[0037] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0038] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0039] like Figures 1 to 11 As shown, a self-cleaning cooking device includes an inner pot 1 with an opening on the front side, and also includes a nozzle 2, an adjustment mechanism 3 and a first fluid channel 4. Furthermore, the nozzle 2 is arranged on the side wall of the inner pot 1 and is used to spray the inside of the inner pot 1. The adjustment mechanism 3 is used to rotate the nozzle 2 to adjust the spray angle of the nozzle 2, and includes a first adjustment member that can be driven by water pressure and a second adjustment member connected to the nozzle 2. The first fluid channel 4 is for high-pressure water to circulate, and its water inlet port is fluidically connected to the high-pressure water source, while the water outlet port is fluidically connected to the water inlet 201 of the nozzle 2. Moreover, when the first fluid channel 4 is in a state of water flowing, the high-pressure water in the first fluid channel 4 drives the first adjustment member and causes the second adjustment member to drive the nozzle 2 to rotate.

[0040] At the end of cooking, the self-cleaning cooking device of the present invention allows water to flow through first fluid channel 4. High-pressure water in first fluid channel 4 is ejected through nozzle 2 to perform high-pressure water washing on the interior of inner pot 1, achieving self-cleaning of the interior of inner pot 1. Furthermore, an adjustment mechanism 3 is provided, comprising a first adjustment member and a second adjustment member. The high-pressure water in first fluid channel 4 drives the first adjustment member, which in turn causes the second adjustment member to rotate nozzle 2, thereby adjusting the spray angle of nozzle 2, avoiding blind spots and ensuring a thorough cleaning of the interior of inner pot 1.

[0041] like Figure 5 As shown, preferably, there are two nozzles 2 and they are respectively arranged on the left and right side walls of the inner tank 1, and the nozzles 2 on both sides are arranged opposite to each other and are respectively located in the middle of the side walls along the front-back direction (such as Figure 2 As shown), there are two regulating mechanisms 3 and two first fluid channels 4, and they correspond to the nozzles 2 on the left and right sides respectively. By arranging nozzles 2 on the left and right sides of the inner tank 1, and configuring a first fluid channel 4 and an regulating mechanism 3 for each nozzle 2, the spraying angle of the nozzles 2 on both sides can be adjusted to better avoid spraying dead angles, thereby better ensuring the cleaning effect. Among them, the nozzles 2 on both sides are arranged to face each other on the left and right, which can balance the water pressure in the first fluid channels 4 on both sides. In this embodiment, each first fluid channel 4 is respectively arranged vertically on the left and right sides of the inner tank 1, and the upper and lower ends of each first fluid channel 4 are bent respectively to facilitate connection with the corresponding pipeline or nozzle 2.

[0042] Furthermore, each of the above-mentioned nozzles 2 is in the shape of an elongated strip and is inserted into the corresponding side wall along the left-right direction, and each nozzle 2 can rotate up and down with the first axis extending forward and backward as the center. In this way, the spray angle of each nozzle 2 can be adjusted by rotating each nozzle 2 up and down. In this embodiment, ball bearings 22 are respectively provided on the front and back sides of each nozzle 2, and connecting shafts (not shown) extending along the first axis direction are respectively fixed at the corresponding positions of the left and right side walls of the inner tank 1, and each connecting shaft is respectively inserted into the corresponding ball bearing 22, thereby realizing the rotation setting of each nozzle 2 on the corresponding side wall of the inner tank 1.

[0043] like Figure 9 、 Figure 10 as well as Figure 11 As shown, the outer shape of each of the above-mentioned nozzles 2 is cylindrical, and a flow channel 20 is provided inside along its own axial direction. One end of the flow channel 20 is the above-mentioned water inlet 201 and the other end is the water outlet 202. And the end surface where the water outlet 202 of each nozzle 2 is located is respectively provided with a guide groove 21 extending forward and backward. Each guide groove 21 is in the shape of a long strip, and each water outlet 202 is respectively located at the center of the corresponding guide groove 21 along its own length direction, and the cross-sectional size of each guide groove 21 increases outward from the water outlet 202. The guide groove 21 on each nozzle 2 can guide the high-pressure water flow sprayed from each water outlet 202 in the front-to-back direction to form a fan-shaped water curtain in the front-to-back direction. With the up and down rotation of each nozzle 2, the high-pressure water can be fully sprayed to various places inside the inner tank 1. In this embodiment, the angle between the front and rear groove walls of the guide groove 21 of each nozzle 2 is 108° (such as Figure 11 As shown), each nozzle 2 can spray a fan-shaped water curtain with a central angle of 108° (as shown Figure 2 shown).

[0044] like Figure 6As shown, in this embodiment, the first adjustment member of each adjustment mechanism 3 is a water wheel 31, and the second adjustment member is a connecting rod 32. The water wheel 31 is mounted in a sealed first mounting chamber 33 and includes a wheel body 311, an axle 312, and wings 313. The axle 312 extends horizontally and passes through the center hole of the wheel body 311. The wings 313 are arranged circumferentially on the wheel surface of the wheel body 311. One end of the connecting rod 32 is pivotally connected to the disc of the wheel body 311, and the other end is pivotally connected to the nozzle 2. Furthermore, one side of the first mounting chamber 33 is connected to the first fluid channel 4. At least one wing 313 of the water wheel 31 extends into the first fluid channel 4 through the connection between the first mounting chamber 33 and the first fluid channel 4, and is positioned horizontally in the first fluid channel 4. During the rotation of the water wheel 31, at least one wing 313 is always positioned horizontally in the first fluid channel 4. In this way, when water is flowing through each first fluid channel 4, the water flowing from bottom to top toward the corresponding nozzle 2 impacts the wing 313 located in the first fluid channel 4 and drives the corresponding water impeller 31 to rotate. The rotating water impeller 31 drives the nozzle 2 to rotate respectively through the corresponding connecting rod 32. In this way, when the high-pressure water in each first fluid channel 4 flows toward the corresponding nozzle 2, it drives the corresponding water impeller 31 to rotate, and the rotating water impeller 31 drives the corresponding nozzle 2 through the corresponding connecting rod 32, thereby adjusting the spray angle of each nozzle 2. In this embodiment, when water is flowing through each first fluid channel 4, the rotation directions of the water impellers 31 in the left and right adjustment mechanisms 3 are opposite (such as Figure 5 As shown in the figure), the rotation directions of the nozzles 2 on both sides are opposite (for example, when the left nozzle 2 rotates upward, the right nozzle 2 rotates downward). On the one hand, it can avoid the collision of the high-pressure jets ejected by the left and right nozzles 2. On the other hand, the nozzles 2 on both sides can fully spray the interior of the inner tank 1 from top to bottom, which helps to improve the cleaning effect of the inner tank 1. The states when the nozzles 2 are adjusted to different angles are shown as follows: Figure 6 and Figure 8 shown.

[0045] like Figure 5As shown, a cooking plate 7 for placing food ingredients is horizontally disposed in the inner pot 1, below the nozzle 2, along the horizontal direction. The bottom of the cooking plate 7 is connected to a rotating shaft 71 extending horizontally through the inner pot 1. A drive mechanism 8 is also included for driving the rotating shaft 71 to rotate about its own axis. Each drive mechanism 8 is disposed on the left and right sides of the inner pot 1 and corresponds to each of the first fluid channels 4. Each drive mechanism 8 comprises a drive element and a transmission element. Each of the first fluid channels 4 extends vertically. After cooking is complete, high-pressure water flows simultaneously through the left and right first fluid channels 4. The high-pressure water flowing in each first fluid channel 4 toward the corresponding nozzle 2 drives the corresponding drive element, which in turn drives the corresponding transmission element, causing the rotating shaft 71 to rotate. After cooking, not only will the inner surface of the cooking plate 7 retain oil stains and other contaminants, but the outer surface will also remain contaminated, making it difficult to clean. By tilting the cooking plate 7 upside down, the present invention utilizes high-pressure water sprayed from each nozzle 2 to thoroughly clean the inner and outer surfaces of the cooking plate 7. This allows for self-cleaning of both the interior of the inner pot 1 and the outer and inner surfaces of the cooking plate 7 simultaneously. Furthermore, the high-pressure water in each first fluid channel 4 is used to drive the cooking plate 7 to rotate via each drive mechanism 8, achieving simultaneous high-pressure water spraying from each nozzle 2 and rotation of the cooking plate 7. In this embodiment, a left-right extending shaft sleeve (not shown) is provided on the outer bottom surface of the cooking plate 7 and is removably connected to the rotating shaft 71 via this shaft sleeve.

[0046] like Figure 7 As shown, each of the aforementioned driving elements is a hydraulic gear 81, and each transmission element is a transmission gear 82 capable of meshing with the corresponding hydraulic gear 81. Furthermore, each hydraulic gear 81 is mounted in a second mounting chamber 83. This second mounting chamber 83 has one side open and connected to the corresponding first fluid channel 4, and the other side also open to allow each hydraulic gear 81 to mesh with the corresponding transmission gear 82. At least one tooth 811 of the hydraulic gear 81 extends into the first fluid channel 4 through the connection between the second mounting chamber 83 and the first fluid channel 4, lying transversely within the first fluid channel 4. During rotation, at least one tooth 811 remains transversely within the first fluid channel 4. Furthermore, each second mounting chamber 83 and the corresponding transmission gear 82 are located in a sealed third mounting chamber (not shown). The ends of the rotating shaft 71 extend into the corresponding third mounting chamber and connect to the center of the corresponding third transmission gear 82. In this way, when the high-pressure water in each first fluid channel 4 flows toward the corresponding nozzle 2, it drives the corresponding hydraulic gear 81 to rotate, and the rotating hydraulic gears 81 drive the corresponding transmission gear 82 to rotate in the same direction, and finally drive the rotating shaft 71 to realize the up and down rotation of the cooking plate 7.

[0047] In this embodiment, each of the aforementioned first installation chambers 33 and second installation chambers 83 is disc-shaped. The size of each first installation chamber 33 matches the corresponding water wheel 31, and each water wheel 31 is coaxially accommodated in the corresponding first installation chamber 33. The size of each second installation chamber 83 matches the corresponding water gear 81, and each water gear 81 is coaxially accommodated in the corresponding second installation chamber 83. Furthermore, each first fluid channel 4 extends tangentially along the cross-section of the corresponding first installation chamber 33 and second installation chamber 83. This allows the high-pressure jet water in each first fluid channel 4 to better drive the corresponding water wheel 31 or water gear 81 to rotate, and also allows water drawn into each installation chamber to quickly flow back into the corresponding first fluid channel 4, preventing water from remaining in each installation chamber.

[0048] Further, if Figure 1 As shown, it also includes a water inlet tank 6 and a high-pressure jet pump 5. The water outlet 61 of the water inlet tank 6 is in fluid communication with the water inlet interface 51 of the high-pressure jet pump 5, and the first water outlet interface 52 and the second water outlet interface 53 of the high-pressure jet pump 5 are in fluid communication with the water inlet ports of each first fluid channel 4. After the water in the water inlet tank 6 enters the high-pressure jet pump 5, it forms high-pressure jet water on the left and right sides of the high-pressure jet pump 5, and the formed high-pressure water is respectively passed into each first fluid channel 4. Figure 3 and Figure 4 As shown, a wastewater outlet 11 is provided on the bottom wall of the inner container 1. The wastewater outlet 11 is in fluid communication with the return water interface 54 of the high-pressure jet pump 5. A filter 9 is provided between the wastewater outlet 11 and the return water interface 54. The cleaned wastewater is filtered by the filter 9 and then flows back to the high-pressure jet pump 5. This allows the cleaning wastewater to be recycled, saving water resources and reducing cleaning costs. Specifically, Figure 4 As shown, the high-pressure jet pump 5 is located below the inner tank 1, and the wastewater outlet 11 is connected to the return water interface 54 via a vertically extending return water channel 110. The filter 9 includes a filter screen 91 disposed in the return water channel 110. A vertically extending vertical rod 92 is fixed to the filter screen 91, and a baffle 93 is fixed to the top of the vertical rod 92. The baffle 93 is located directly above the wastewater outlet 11 and has a vertical gap between it and the wastewater outlet 11. The filter screen 91 can intercept particles, oil, etc. in the returned cleaning wastewater, while the baffle 93 can prevent the high-pressure jet from entering the wastewater outlet 11.

[0049] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two components or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. It can be a direct connection between the above-mentioned first part and the second part, or it can be an indirect connection between the first part and the second part through at least one third party. The third party can be a fluid channel such as a pipe, channel, conduit, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
