Description

Technical Field

[0001] The utility model relates to the field of kitchen equipment, in particular to a cooking device. Background Art

[0002] The cooking device may include a housing and an inner container, wherein a cooking cavity may be formed in the inner container. A heating pipe may be provided in the cooking cavity to heat the air in the cooking cavity, thereby completing a grilling cooking function.

[0003] The heat generated by the heat pipe cannot be fully irradiated on the cooked food. The existing design sets the inner wall surface of the inner pot top plate to be a wall surface that can reflect heat. However, the reflective wall surface is set as an integral part of the inner pot, which is inconvenient to clean.

[0004] Some designs have a connection structure on the inner pot to prevent the reflection avoidance surface from being removed from the inner pot. However, the connection structure is relatively complex, making it difficult to remove the reflection avoidance surface from the inner pot. The inner pot structure is also relatively complex, increasing the design cost of the inner pot. Therefore, the present application proposes a cooking device. Summary of the Invention

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

DETAILED DESCRIPTION

[0079] In order to make the purpose and implementation of this application clearer, the exemplary implementation of this application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only part of the embodiments of this application, not all of the embodiments.

[0080] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

It should be understood that the terms used in this manner are interchangeable under appropriate circumstances.

[0082] The terms "comprise," "include," and "have," and any variations thereof, are intended to cover but not exclude inclusion; for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0083] The present application proposes a cooking device 100 , which will be described below with reference to the accompanying drawings.

[0084] refer to Figure 1-Figure 3 The cooking device 100 may include a housing 1. The housing 1 may be used to protect components located inside the housing 1.

[0085] The height direction of the housing 1 can be from the bottom to the top of the housing 1. The housing 1 can have a length direction. The length direction of the housing 1 can be from one side end to the other side end of the housing 1. The housing 1 can have a front-to-back direction. The front of the housing 1 can be the side of the housing 1 facing the user. Among the height direction, length direction, and front-to-back direction of the housing 1, any two directions can be perpendicular to each other.

[0086] refer to Figure 2-Figure 4 The cooking device 100 may include an inner container 2. The inner container 2 may be disposed within the housing 1. A cooking cavity 21 may be formed within the inner container 2. The cooking cavity 21 may be a cavity for placing food. A cooking cavity opening 211 may be provided at the front end of the cooking cavity to facilitate placing food into or removing food from the cooking cavity.

[0087] refer to Figure 2-Figure 4 The cooking device 100 may include a door 3. The door 3 may be movably connected to the front side of the housing. The door 3 may be rotatably connected to the housing 1. The door 3 may be located at the front end of the cooking cavity opening and is used to open or close the cooking cavity opening 211.

[0088] In the present application, the cooking device 100 may include a first heating device, which may be used to heat the air in the inner pot.

[0089] In this application, reference is made to Figure 5-Figure 7 The first heating device may include a first heating tube 4. The first heating tube 4 may be used to heat the air within the inner container. There may be at least two first heating tubes 4. The first heating tube 4 may be an infrared heating tube that heats the air within the inner container through thermal radiation. Compared to existing metal heating tubes, infrared heating tubes have higher heat transfer efficiency.

[0090] The first heating tube 4 may include a first heating section 41. The first heating section 41 may be disposed within the inner container. The central axis of the first heating section may be parallel to the front-to-back direction of the housing. The first heating section may have two sections. The two first heating sections may be spaced apart along the length of the housing.

[0091] The first heating tube 4 may include a second heating section 42. The second heating section 42 may be disposed in the inner pot. Both ends of the second heating section 42 may be connected to one end of the two first heating sections near the cooking cavity opening, respectively.

[0092] The second heating section 42 may include a first sub-heating section 421. The central axis of the first sub-heating section 421 may be perpendicular to the central axis of the first heating section, so that the central axis of the first sub-heating section 421 may be parallel to the length direction of the box shell.

[0093] A plane perpendicular to the height direction of the box shell may be defined as the first plane. Among two adjacent first heating tubes, one first heating tube is arranged around the outside of the other first heating tube, and the projections of the two adjacent first heating tubes on the first plane are arranged at an interval.

[0094] refer to Figure 5-Figure 7 The distance between the center axes of two adjacent first heating sections in the longitudinal direction of the housing is a first distance L1. The first sub-heating sections of the two first heating tubes are adjacently arranged, and the distance between the center axes of the two adjacent first sub-heating sections in the front-to-back direction of the housing is a fourth distance L4. Where L4 < L1.

[0095] The first heating tube is set as an infrared heating tube, so that the heat transfer efficiency of the first heating tube is high. The first heating tube is set to include a first heating section and a second heating section. The central axis of the first heating section can be parallel to the front and rear directions of the box shell, and the central axis of the first sub-heating section 421 is parallel to the length direction of the box shell. L4 < L1, which can make the heating tubes at the front and rear of the inner pot relatively uniform, and the temperature of the first heating section setting area and the second heating section setting area is relatively more uniform, thereby improving the cooking effect.

[0096] Wherein, L4 / L1 < the fifth parameter value. The fifth parameter value can be any value between 2 / 3 and 1. The fifth parameter value can be 1, and L4 / L1 < 1. This can prevent the first heating tubes at the front of the inner pot from being too sparse, and the temperatures in the first and second heating segment areas are relatively more uniform, improving the cooking effect.

[0097] L4 / L1 ≥ the sixth parameter value. The sixth parameter value can be any value between 1 / 3 and 1 / 2. Among them, the sixth parameter value can be 1 / 2, and L4 / L1 ≥ 1 / 2. It can prevent the first heating tubes in the front of the inner pot from being too dense, and the temperatures in the first heating segment setting area and the second heating segment setting area are relatively more uniform, thereby improving the cooking effect. Setting L4 / L1 = 1 / 2 makes the temperatures in the first heating segment setting area and the second heating segment setting area relatively more uniform, and the cooking effect is good.

[0098] In this application, the distance between the first sub-heating section closest to the front end of the inner pot and the front end of the inner pot in the front-to-back direction of the housing is a fifth distance L5, where L5 is less than L1. This prevents a significant difference in the density of the first heating tubes at the front end of the inner pot from being too different from that in other areas of the inner pot, thereby achieving a more uniform temperature throughout the inner pot and achieving a better cooking effect.

[0099] Wherein, L5 / L1 < the seventh parameter value. The seventh parameter value can be any value between 2 / 3 and 1. The seventh parameter value can be 1, and L5 / L1 < 1. This can prevent the first heating tube at the front end of the inner pot from being too sparse, making the temperature throughout the inner pot more uniform.

[0100] L5 / L1≥eighth parameter value. The eighth parameter value can be any value between 1 / 3-1 / 2. Among them, the eighth parameter value can be 1 / 2, L5 / L1≥1 / 2. It can avoid the first heating tubes at the front end of the inner tank being too dense, making the temperature in the inner tank more uniform. Setting L5 / L1=1 / 2 can avoid the large difference between the density of the first heating tubes at the front end of the inner tank and the density of the first heating tubes in other areas of the inner tank, making the temperature in the inner tank more uniform.

[0101] The fifth distance and the fourth distance can be equal, so that the density of the first heating tubes at the front end of the inner container is similar, making the temperature in each part of the inner container more uniform.

[0102] In this application, reference is made to Figure 5-Figure 8 The inner container 2 may include a first side panel 22. The first side panel 22 may be provided at one end of the inner container in the longitudinal direction of the container shell. The inner container 2 may include a second side panel 23. The second side panel 23 may be provided at the other end of the inner container in the longitudinal direction of the container shell. In other words, the first side panel 22 and the second side panel 23 may be provided at the respective ends of the inner container in the longitudinal direction of the container shell.

[0103] The inner liner 2 may include an inner liner top plate 24, which may be disposed at the top of the inner liner. A first transition plate 251 may be connected between the inner liner top plate and the first side plate. The inner surface of the first transition plate is a curved surface. A second transition plate 252 may be connected between the inner liner top plate and the second side plate. The inner surface of the second transition plate is a curved surface.

[0104] refer to Figure 5-Figure 8 The distance between the central axis of the first heating section and the first side plate in the length direction of the box shell is a second distance L2. The distance between the central axis of the first heating section and the second side plate in the direction of the box shell is a third distance L3.

[0105] Wherein, L2 / L1 ≥ the first parameter value. The first parameter value can be any value between 1 / 5 and 4 / 15. The first parameter value can be 1 / 4, and L2 / L1 ≥ 1 / 4. Setting L2 / L1 ≥ 1 / 4 can prevent L2 / L1 from being too small, avoid the first heating section near the first side plate from being too dense, and make the temperature near the first side plate relatively high, avoid causing large temperature differences among different parts of the inner pot, and improve the cooking effect.

[0106] Wherein, L2 / L1 ≤ the second parameter value. The second parameter value can be any value between 1 / 3 and 2 / 3. The second parameter value can be 1 / 3, and L2 / L1 ≤ 1 / 3. Setting L2 / L1 ≤ 1 / 3 can prevent L2 / L1 from being too large, thus preventing the first heating section near the first side plate from being too sparse, resulting in a relatively low temperature near the first side plate, avoiding large temperature differences across the inner pot and improving the cooking effect.

[0107] Setting L2 / L1≥1 / 4 and L2 / L1≤1 / 3 can make the first heating section near the first side panel and the first heating section in other areas relatively uniform, and can make the temperature in various places in the inner pot relatively uniform, avoid excessive temperature difference, and improve cooking effect.

[0108] The second parameter value can be 1 / 2, L2 / L1≤1 / 2. Setting L2 / L1≤1 / 2 can prevent L2 / L1 from being too large, preventing the first heating section near the first side plate from being too sparse, making the temperature near the first side plate relatively low, avoiding large temperature differences across the inner pot, and improving the cooking effect.

[0109] Setting L2 / L1≥1 / 4 and L2 / L1≤1 / 2 can make the first heating section near the first side panel and the first heating section in other areas relatively uniform, and can make the temperature in various places in the inner pot relatively uniform, avoid excessive temperature difference, and improve cooking effect.

[0110] Wherein, L3 / L1 ≥ the third parameter value. The third parameter value can be any value between 1 / 5 and 4 / 15. The third parameter value can be 1 / 4, and L3 / L1 ≥ 1 / 4. Setting L3 / L1 ≥ 1 / 4 can prevent L3 / L1 from being too small, avoid the first heating section near the second side plate from being too dense, and make the temperature near the second side plate relatively high, avoid causing large temperature differences between different parts of the inner pot, and improve the cooking effect.

[0111] Wherein, L3 / L1 ≤ the fourth parameter value. The fourth parameter value can be any value between 1 / 3 and 2 / 3. The fourth parameter value can be 1 / 3, and L3 / L1 ≤ 1 / 3. Setting L3 / L1 ≤ 1 / 3 can prevent L3 / L1 from being too large, thus preventing the first heating section near the second side plate from being too sparse, resulting in a relatively low temperature near the second side plate, avoiding large temperature differences across the inner pot and improving cooking performance.

[0112] Setting L3 / L1≥1 / 4 and L3 / L1≤1 / 3 can make the first heating section near the second side panel and the first heating section in other areas relatively uniform, and can make the temperature in various places in the inner pot relatively uniform, avoid excessive temperature difference, and improve cooking effect.

[0113] The fourth parameter value can be 1 / 2, and L3 / L1≤1 / 2. By setting L3 / L1≤1 / 2, it can be avoided that L3 / L1 is too large, and the first heating section near the second side plate is too sparse, so that the temperature near the second side plate is relatively low, and the temperature difference in the inner container is large, and the cooking effect is improved.

[0114] By setting L3 / L1≥1 / 4 and L3 / L1≤1 / 2, the first heating section near the second side plate and the first heating section in other areas can be relatively uniform, the temperature in the inner container can be relatively uniform, the temperature difference can be avoided to be too large, and the cooking effect is improved.

[0115] In the present application, with reference to Figure 5-Figure 8 , the first heating pipe can have two. The distance between the first side plate and the second side plate in the length direction of the box shell is a sixth distance L6, L6=3L1+L3+L2, so that the distance between the first side plate and the second side plate matches the number of the first heating pipe, and the temperature in the inner container is relatively uniform.

[0116] In the present application, the first heating pipe closest to the rear end of the inner container is an inner first heating pipe. The first heating section of the inner first heating pipe is an inner first heating section. The second heating section of the inner first heating pipe is an inner second heating section. The first sub-heating section of the inner first heating pipe is an inner first sub-heating section. The central axis of the inner first heating section can be coplanar with the central axis of the inner first sub-heating section. The central axis of the inner first heating section can be coplanar with the central axis of the inner second heating section.

[0117] In the present application, the central axis of the first heating section and the central axis of the second heating section are coplanar. The central axis of the first heating section and the central axis of the first sub-heating section are coplanar. The central axes of the first heating pipes are all located in the same plane.

[0118] In the present application, with reference to Figure 9-10 , the cooking device can include a heating disc 5. The heating disc 5 can include a first surface 51. The first surface 51 can be used to place cooking food materials.

[0119] When the heating disc 5 is arranged in the inner container, the heating disc can have a first position. When the heating disc is in the first position, the minimum distance between the first surface and the central axis of the inner first heating section in the height direction of the box shell is a first distance H1. H1 2 ≥4 / 7L1, H1 2 ≤L1, so that the temperature at the first surface is relatively uniform, and when the food materials to be cooked are placed on the first surface corresponding to the first distance, the local temperature is avoided to be too high or too low, so that the cooking effect is good.

[0120] In the present application, the distance between the rear end of the inner first heating section and the central axis of the first sub-heating section in the front-rear direction of the box shell is 2L1.

[0121] When the heating disc is in the first position, the distance from the center of the first surface 51 to the center axis of the two inner first heating sections is equal, and the distance from the center of the first surface 51 to the center axis of the inner first sub-heating section in the front-rear direction of the box shell is L1, so as to better determine the first position.

[0122] According to the law of heat radiation, the radiation energy of a point received by the first heating pipe is proportional to the inverse of the square of the distance of the point from the first heating pipe.

[0123] Reference Figure 9-10 The center point of the first surface 51 can be X point. The distance from the X point to the center axis of one of the inner first heating sections is the seventh distance. The square of the seventh distance is L7 2 = 1 / 4L1 2 +H1 2 . The distance from the X point to the center axis of the other inner first heating section is the eighth distance. The square of the eighth distance is L8 2 = 1 / 4L1 2 +H1 2 . The distance from the X point to the center axis of the inner first sub-heating section is the ninth distance L9. The square of the ninth distance is L9 2 =L1 2 +H1 2 .

[0124] The radiation energy of the X point is X 能量 =2 / (1 / 4L1 2 +H1 2 )+1 / (L1 2 +H1 2 ).

[0125] A plane parallel to the first plane and passing through the X point is defined as the second plane. A point Y is selected on the second plane, which is the closest point to X and directly below the inner first heating pipe.

[0126] The distance from the Y point to one of the inner first heating sections is the tenth distance L10. The square of the tenth distance is L10 2 =H1 2 . The distance from the Y point to the other inner first heating section is the eleventh distance L11. The square of the eleventh distance is L11 2 =L1 2 +H1 2 . The distance from the Y point to the center axis of the inner first sub-heating section is the twelfth distance L12. The square of the twelfth distance is L12 2 =L1 2 +H1 2 . The radiation energy of the Y point is Y 能量 =1 / H1 2 +2 / (L1 2 +H12 ). Y 能量 = X 能量 , calculated H1 2 = L1 2 .

[0127] A point Z is selected on the second plane, which is the point farthest from X and directly below the inner first heating section. The distance between the point Z and one of the inner first heating sections is a thirteenth distance L13. The square of the thirteenth distance is L13 2 = H1 2 . The distance between the point Z and the other inner first heating section is a fourteenth distance L14. The square of the fourteenth distance is L14 2 = L1 2 + H1 2 . The distance between the point Z and the center axis of the inner first sub-heating section is a fifteenth distance L15. The square of the fifteenth distance is L15 2 = 4L1 2 + H1 2 .

[0128] The radiant energy of the point Y is Y 能量 = 1 / H1 2 + 1 / (L1 2 + H1 2 ) + 1 / (4L1 2 + H1 2 ). Z 能量 = X 能量 , calculated H1 2 = 4 / 7L1 2 . Setting H1 2 ≥ 4 / 7L1 2 , H1 2 ≤ L1 2 , can make the temperature on the first plane relatively uniform when the heating disc is in the first position, avoid the first plane being too close or too far from the inner first heating section, and cause a large temperature difference on the first plane, so that the heating disc is in the first position, which is more conducive to cooking and ensures the uniformity of the cooked food.

[0138] The blower may include a fan motor. The fan motor may be connected to the fan to drive the fan to rotate. The fan motor drives the fan to rotate so that air in the cooking cavity flows into the blower cavity through the air inlet and then flows back into the cooking cavity through the air outlet.

[0139] The rotating shaft of the fan motor can pass through the rear panel of the inner tank from behind and be inserted into the fan cavity and connected to the fan, so that most of the fan motor is arranged outside the inner tank to avoid the steam or high temperature in the inner tank from affecting the fan motor.

[0140] In the present application, the cooking device may include a third heating tube. The third heating tube may be used to heat the air in the fan cavity. The third heating tube may be at least partially disposed in the fan cavity to heat the air in the fan cavity.

[0143] In the present application, the inner container may include an inner container top plate 24. The inner container top plate 24 may be provided on the top of the inner container.

[0144] The cooking device 100 may include a first heating device. The first heating device may include a first heating tube 4. The first heating tube may be at least partially disposed in the cooking cavity. The first heating tube may be used to heat the air in the inner pot.

[0145] In this application, reference is made to Figure 14-16 The cooking device 100 may include a support mechanism 6. The support mechanism 6 may be disposed in the cooking cavity, and the support mechanism 6 may be connected to the top plate of the inner pot. The support mechanism 6 may be used to fix the first heating tube 4.

[0146] In this application, reference is made to Figure 14-16The first heating tube 4 can have a locked position. The first heating tube 4 can have an unlocked position. When the first heating tube is in the locked position, the first heating tube can be restrained by the support mechanism so that the first heating tube is fixed to the top plate of the inner container. When the first heating tube is in the unlocked position, the first heating tube is disengaged from the support mechanism so that the first heating tube is disengaged from the top plate of the inner container.

[0147] In this application, reference is made to Figure 14-16 The cooking device may include a first connecting member 7. The first connecting member 7 may be disposed in the cooking cavity. The first connecting member may be connected to the first heating tube. The first connecting member includes a first connecting portion 71.

[0148] The cooking device may include a reflective plate 8. The reflective plate 8 may be disposed within the cooking cavity. The reflective plate 8 may include a second connecting portion 81, which cooperates with the first connecting portion to removably connect the reflective plate to the first connecting member. When the reflective plate is connected to the first connecting member, the reflective plate is disposed above the first heating tube. A space is provided between the reflective plate and the first heating tube, and the reflective plate is connected to the first connecting member via the second connecting portion and the first connecting portion.

[0149] A reflecting plate is provided. When the reflecting plate is connected to the first connecting member, the reflecting plate is provided above the first heating tube. There is a gap between the reflecting plate and the first heating tube, so that the reflecting plate can reflect the heat generated by the first heating tube so that the heat is irradiated on the food, thereby fully utilizing the thermal energy and improving the heating efficiency. The reflecting plate can block part of the inner pot. When cooking, oil will splash onto the reflecting plate, so that the part of the inner pot top plate blocked by the reflecting plate is relatively clean.

[0150] The reflective plate is detachably connected to the first connecting piece, so that the reflective plate can be removed for cleaning, which is convenient and thorough, and solves the problem of small space and difficulty in cleaning the top plate of the inner tank.

[0151] By setting up a support mechanism, the first heating tube can be confined on the inner tank top plate through the support mechanism, and the first heating tube can be separated from the inner tank top plate through the support mechanism. The front end of the first heating tube can move downward, which can facilitate the disassembly and assembly of the reflector plate.

[0152] In this application, reference is made to Figure 14-16 The reflective plate may include a reflective surface 82. When the reflective plate is connected to the first connector, the reflective surface is located on a side of the reflective plate close to the first heating tube. The vertical distance from any point on the reflective surface to the first heating tube is a sixteenth distance L16.

[0153] Wherein, L16 ≥ the ninth parameter value. The ninth parameter value can be any value between 4 mm and 6 mm. The ninth parameter value can be 5 mm. L16 ≥ 5 mm can prevent the sixteenth distance from being too small, thereby preventing the reflector from failing to reflect heat, and ensure that the reflector can properly reflect heat.

[0154] L16 ≤ the tenth parameter value. The tenth parameter value can be any value between 15 mm and 25 mm. The tenth parameter value can be 20 mm. L16 ≤ 20 mm can prevent the sixteenth distance L16 from being too large, thereby preventing poor reflection effects and preventing the overall height of the cooking device from being too large.

[0155] L16≥5mm, L16≤20mm can prevent the sixteenth distance from being too small, preventing the reflection plate from being unable to reflect heat, and allowing the reflection plate to reflect heat normally. It can also prevent the sixteenth distance L16 from being too large, preventing poor reflection effect, and preventing the overall height of the cooking device from being too large.

[0156] In this application, reference is made to Figure 16-17 The second connecting portion 81 may be a second through-hole that penetrates the reflector in the thickness direction of the reflector. The first connecting portion 71 may include a supporting surface 711. The first connecting portion 71 may include a limiting post 712.

[0157] In the present application, there may be several first heating tubes, one first heating tube may have several sub-heating tubes 43, the first connecting piece may be connected to at least two sub-heating tubes, the sub-heating tubes connected to the first connecting piece may belong to the same first heating tube, or the sub-heating tubes connected to the first connecting piece may belong to different first heating tubes.

[0158] In this application, reference is made to Figure 17-Figure 19 The cooking device may include a connecting piece 91, which can connect the first connecting member and the first heating tube. A receiving groove 911 is formed on the connecting piece. The receiving groove 911 can be formed by bending the connecting piece 91. The first heating tube can be disposed in the receiving groove. The connecting piece 91 is connected to the first heating tube 4 to confine the first heating tube in the receiving groove 911.

[0159] In this application, reference is made to Figure 20-24The support mechanism 6 may include a base 61. The base 61 may be connected to the inner container top plate 24. A first mounting hole 611 may be formed on the base 61. The first mounting hole 611 includes a first mounting hole end 6111 and a second mounting hole end 6112 that are arranged opposite to each other in the longitudinal direction of the first mounting hole. The first mounting hole end of the first mounting hole is provided with a first opening 6113.

[0160] The support mechanism 6 may include a first elastic member 62, which may be disposed in the first mounting hole. The first elastic member may be retractable upon receiving a force. The first elastic member may be a spring.

[0161] The support mechanism 6 may include a first support member 63. The first support member 63 may be at least partially disposed within the first mounting hole. The first support member may be located on a side of the first elastic member away from the second end of the mounting hole. The first support member 63 may be connected to the first elastic member 62.

[0162] The first support member may have a first position. The first support member may have a second position. When the first support member is in the first position, the first support member may be partially located outside the first mounting hole through the first opening. When the first support member is in the first position, the first elastic member is in its original length or compressed state. When the first support member is in the second position, the first elastic member is in a compressed state.

[0163] When the first support member switches from the first position to the second position, the first support member approaches the second end of the mounting hole and compresses the first elastic member. When the first support member switches from the second position to the first position, the first elastic member drives the first support member away from the second end of the mounting hole.

[0164] When the first heating tube is in the locked position, the first support member is in the first position and can support the first heating tube. When the first support member is in the second position, the first heating tube is in the unlocked position.

[0165] A supporting mechanism is provided including a base, a first elastic member and a first supporting member, which can lock the first heating tube on the top plate of the inner tank to fix the first heating tube, and can also separate the first heating tube from the top plate of the inner tank, thereby facilitating the disassembly of the first heating tube.

[0166] The first support member can be pushed from the first position to the second position by an external force, so that the first heating tube can be moved from the locked position to the unlocked position.

[0167] The sub-heating tube may include a third sub-heating tube. When the first heating tube is in the locked position, the third sub-heating tube is arranged on the first support member.

[0168] The length direction of the first mounting hole may be perpendicular to the height direction of the housing. Specifically, the length direction of the first mounting hole may be parallel to the front-to-back direction of the housing. The central axis of the third sub-heating tube may be parallel to the length direction of the housing.

[0169] In this application, reference is made to Figure 20-24 The reflecting plate may be formed with a third through hole 83. The reflecting plate may be sleeved on the base through the third through hole, so that the first support member on the base may be located below the reflecting plate, so that the first support member may support the first heating tube.

[0170] There may be a plurality of second through holes, and the plurality of second through holes may be arranged around the outside of the third through hole. There may be four second through holes.

[0171] In this application, reference is made to Figure 20-26 A first insertion slot 612 may be formed on the base 61. The first insertion slot 612 has a slot opening 6121.

[0172] A second opening 6114 is provided at the second end of the mounting hole, and the first mounting hole is connected to the first insertion slot through the second opening. The first support member and the first elastic member are provided in the first mounting hole through the first insertion slot and the second opening.

[0173] The support mechanism 6 may include a first limiting plate 64. The first limiting plate 64 may be inserted into the first insertion slot through the slot opening to confine the first elastic member and the first support member within the first mounting hole, thereby preventing the first elastic member and the first support member from falling out of the first mounting hole and ensuring normal operation of the first support member.

[0174] When the first limiting plate 64 is inserted into the first inserting slot, the first elastic member may be compressed, or the first elastic member is in the original length state.

[0175] In the present application, the first plug-in slot may have a plug-in slot inner side surface 6122. The slot opening may be provided at one end of the plug-in slot inner side surface. The second opening may be provided on the plug-in slot inner side surface.

[0176] In the present application, a second mounting hole 613 may be formed on the base 61, and the second mounting hole may be provided on a side of the first plug-in slot away from the first mounting hole. A third opening 6131 and a fourth opening 6132 are provided at both ends of the length direction of the second mounting hole, respectively. The second mounting hole is connected to the first plug-in slot through the fourth opening. The first elastic member and the first support member are provided in the first mounting hole through the third opening, the fourth opening, the first plug-in slot, and the second opening, so as to facilitate the installation of the first support member and the first elastic member into the first mounting hole or removal from the first mounting hole. The third opening may be provided on the inner side of the plug-in slot. The length direction of the second mounting hole may be parallel to the length direction of the first mounting hole. The second mounting hole may be provided opposite to the first mounting hole.

[0177] In this application, reference is made to Figure 25 The inner side surface 6122 of the insertion slot may include a first inner side surface 61221. The first inner side surface may be located at the bottom end of the inner side surface of the insertion slot. The first inner side surface is an inclined surface, with the end of the first inner side surface away from the slot opening located on a side of the first inner side surface located at the slot opening closer to the bottom end of the housing. This facilitates insertion of the first limiting plate into the first insertion slot and prevents the first limiting plate from falling out of the first insertion slot.

[0178] In the present application, a limit plate hole 641 may be formed on the first limit plate. The limit plate hole 641 may be located at an end of the first limit plate near the second mounting hole. The limit plate hole 641 may extend through the first limit plate. The length direction of the limit plate hole may be parallel to the length direction of the first mounting hole.

[0179] The limiting plate hole can be a circular hole. The diameter of the limiting plate hole can be smaller than the outer diameter of the first elastic member, thereby preventing the first elastic member from being dislodged from the first mounting hole through the limiting plate hole. The provision of the limiting plate hole facilitates removal of the first limiting plate from the first insertion slot.

[0180] In the present application, the first mounting hole can have at least one pair, and the two paired first mounting holes are spaced apart in the length direction of the first mounting hole. Among the two paired first mounting holes, the end of any first mounting hole close to the other first mounting hole is an end of the first mounting hole where the first opening is set.

[0181] The first elastic member and the first support member can each have at least one pair. The two paired first elastic members are respectively arranged in the two paired first mounting holes, and the two paired first support members are respectively located in the two paired first mounting holes. When the first support member is in the first position, the two paired first support members are in contact or spaced apart. When the first support member is in the second position, the two paired first support members are spaced apart. This allows the two first support members to jointly support the first heating tube, providing a larger space for the movement of the first heating tube when the two first support members are in the second position, and facilitating the switching of the first heating tube between the locked position and the unlocked position.

[0182] When the first heating tube is in the locked position, the two paired first support members are respectively in the first position, the first heating tube is arranged on the two paired first support members, and the two paired first support members can support the first heating tube. When the two paired first support members are in the second position, the first heating tube can be in the unlocked position.

[0183] The two first support members can be pushed from the first position to the second position by external force, so that the first heating tube can be moved from the locked position to the unlocked position.

[0184] In the present application, the first support member may be a sphere, and the first heating tube may be pulled downward to move the first support member from the first position to the second position, and the first heating tube may be switched from the locked position to the unlocked position.

[0185] In this application, reference is made to Figure 20-26 The first mounting hole may include a first mounting segment 6115 and a second mounting segment 6116. The first mounting segment is located on a side of the second mounting segment near the second end of the mounting hole. The diameter of the first mounting segment may be larger than the diameter of the second mounting segment. The maximum diameter of the first support member may be larger than the diameter of the second mounting segment, and the maximum diameter of the first support member may be smaller than the diameter of the first mounting segment, so that the first support member can be partially located within the first mounting hole and partially located outside the first mounting hole.

[0186] The diameter of the limiting plate hole may be smaller than the diameter of the first mounting section. The diameter of the limiting plate hole may be smaller than the diameter of the second mounting hole.

[0187] In this application, reference is made to Figure 20-26 The base includes a first base 614. The first base is formed with a first mounting hole. The first base is formed with a first plug slot. The first base is formed with a second mounting hole to facilitate the installation and design of the support mechanism.

[0188] The base may include a second base 615. The second base is formed with a first mounting hole. The second base is formed with a first insertion slot. The second base is formed with a second mounting hole to facilitate the installation and design of the support mechanism.

[0189] The first base may be provided with a third connecting portion 6141, which may be provided on the top of the first base. The third connecting portion may include a threaded column, which is threadedly connected to the inner liner top plate, or a through hole is formed in the inner liner top plate, and the third connecting portion is inserted into the through hole in the inner liner top plate and threadedly connected to a nut located above the inner liner top plate.

[0190] refer to Figure 20-26 The second base may be provided with a fourth connection portion 6151, which may be provided on the top of the second base. The fourth connection portion may include a threaded column, which is threadedly connected to the inner liner top plate. Alternatively, the inner liner top plate may be formed with a through hole, and the fourth connection portion may be inserted into the through hole in the inner liner top plate and threadedly connected to a nut located above the inner liner top plate.

[0191] In the present application, the first heating tube may be a metal heating tube, and a heat dissipation coating may be applied to the outer surface of the first heating tube. The heat dissipation coating may be partially applied to the outer surface of the first heating tube. The heat dissipation coating may be applied to the entire outer surface of the first heating tube. The heat dissipation coating may have a thickness of a first thickness M1. The coating may be black.

[0192] The main advantages of thermal radiation over convection include the absence of a medium, long-distance transmission, and high heat transfer efficiency. Thermal radiation transfers heat via electromagnetic waves without any intermediate medium, while convection requires a medium such as air to transfer heat. Therefore, thermal radiation is more efficient.

[0193] The outer surface of the first heating tube is coated with a heat dissipation coating, which not only dissipates heat through heat conduction but also improves heat dissipation efficiency by increasing the infrared emissivity of the heat source surface. This coating changes the heating method of the first heating tube from convection to a combination of convection and radiation, with the proportion of radiation significantly increased compared to before, thereby improving heat transfer efficiency.

[0194] The first thickness K1 is greater than or equal to the eleventh parameter value. The eleventh parameter value can be any value between 15 μm and 20 μm. The eleventh parameter value can be 20 μm. The first thickness is greater than or equal to 20 μm. This can prevent the heat dissipation coating from being too thin, thereby preventing the heat dissipation effect from being affected.

[0195] The first thickness is ≤ the twelfth parameter value. The twelfth parameter value can be any value between 30 μm and 35 μm. The eleventh parameter value can be 30 μm. The first thickness is ≤ 30 μm. This can prevent the heat dissipation coating from being too thick, as a thick coating would hinder effective heat conduction and result in poor heat dissipation.

[0196] In the present application, the cooking device may include a fourth heating tube. The fourth heating tube is at least partially located below the inner pot to heat the air inside the inner pot. The fourth heating tube may include a fourth heating portion. The fourth heating portion may be located below the inner pot.

[0197] In the present application, the cooking device may include a steam generator. The steam generator may be located within the housing. The steam generator may be located outside the inner pot. The steam generator may be located behind the inner pot. The steam generator is used to generate steam to supply steam to the cooking cavity, allowing the cooking device to steam food.
