Description

TECHNICAL FIELD

[0001] The utility model relates to knob assembly technical field, specifically, relate to a switch assembly and cooking equipment. BACKGROUND

[0002] In the case that the cooking equipment has multiple cooking zones, a switch component needs to be provided for each cooking zone. In order to control multiple switch components at the same time, a linkage structure can be used to link the multiple switch components. However, after adding the linkage structure, the linkage structure and the multiple switch components will occupy a large space, thereby increasing the volume of the cooking equipment and causing inconvenience to the user in using the cooking equipment. SUMMARY

[0003] The utility model aims at solving one of the technical problems existing in the prior art or related art.

[0004] Therefore, in a first aspect, the utility model provides a switch assembly, which comprises: at least two knob assemblies; a linkage member connected to adjacent two knob assemblies, the adjacent two knob assemblies being linked to each other through the linkage member, the linkage member comprising a first linkage part and a second linkage part, the second linkage part being arranged at both ends of the first linkage part, the second linkage part being used for cooperating with the knob assembly to link, in the length direction of the first linkage part, a part of the first linkage part being arranged opposite to the second linkage part, and another part of the first linkage part being arranged opposite to the knob assembly.

[0005] In the case that the cooking equipment has multiple cooking zones, one knob assembly can adjust the heating power of one cooking zone. The linkage member is used to link at least two knob assemblies, when one knob assembly is rotated, the remaining knob assemblies can also be rotated under the driving of the linkage member, thereby realizing the gear linkage of multiple knob assemblies, that is, the gear of one knob assembly can be adjusted, and the gears of other knob assemblies can also be adjusted accordingly. When the user uses multiple cooking zones of the cooking equipment at the same time, the user does not need to adjust the gears of multiple knob assemblies one by one, thereby providing convenience for the user in using the cooking equipment.

[0006] The linkage member comprises a first linkage part and a second linkage part, the second linkage part is arranged at both ends of the first linkage part respectively, one second linkage part is used for cooperating with one knob assembly, so that one knob assembly is linked with an adjacent knob assembly through the first linkage part and the second linkage part. In the length direction of the first linkage part, one part of the first linkage part is opposite to the second linkage part, and the other part of the first linkage part is distributed in a staggered manner with the second linkage part, that is, the other part of the first linkage part is not provided with the second linkage part corresponding thereto, on the basis of which, the knob assembly can be opposite to the other part of the first linkage part, so that the knob assembly is arranged on one side of the first linkage part in the length direction. In the width direction of the knob assembly, the knob assembly does not protrude out of the first linkage part, or only a part of the knob assembly protrudes out of the first linkage part. By arranging the knob assembly in the length direction of the linkage member, the space occupied by the knob assembly in the width direction of the first linkage part can be reduced, so that the overall width of the switch assembly can be reduced, the volume of the switch assembly can be reduced, and then the occupied space of the switch assembly in the cooking equipment can be reduced, thereby facilitating the use of the cooking equipment by the user.

[0007] In addition, the switch assembly in the above technical scheme provided by the utility model can also have the following additional technical features:

[0008] In some technical solutions, optionally, the width of the first linkage part is greater than the width of the second linkage part.

[0009] The width of the first linkage part is relatively large, and the first linkage part can leave sufficient space for arranging the knob assembly in the width direction at the end of the first linkage part, and along the width direction of the first linkage part, it is ensured that the knob assembly does not protrude out of the first linkage part, or only a part of the knob assembly protrudes out of the first linkage part.

[0010] In some technical solutions, optionally, along the width direction of the first linkage part, the second linkage part is located at the side of the first linkage part, and the second linkage parts arranged at both ends of the first linkage part are located at the same side or different sides of the first linkage part.

[0011] The second linkage part is arranged at the end of the first linkage part, and the second linkage part is arranged at the side of the first linkage part in the width direction, so that the second linkage part provides more avoiding space for the knob assembly.

[0012] In this case, all the knob assemblies can be arranged in the length direction of the first linkage part, so that the knob assemblies do not protrude out of the first linkage part along the width direction of the first linkage part. Or, most of the knob assemblies are arranged in the length direction of the first linkage part, and a small part of the knob assemblies protrude out of the first linkage part along the width direction of the first linkage part.

[0013] In the width direction of the first linkage part, the two adjacent knob assemblies can be arranged on the first side of the first linkage part, or one of the two adjacent knob assemblies is arranged on the first side of the first linkage part, and the other is arranged on the second side of the first linkage part.

[0014] In some technical solutions, the two second linkage parts arranged at the two ends of the first linkage part are located on different sides of the first linkage part, and the knob assembly has a plurality of switch gears, and when any knob assembly is rotated in the first direction, the switch gear of the knob assembly is increased.

[0015] When a user rotates one knob assembly, the knob assembly will drive the linkage to move during rotation, so that the linkage drives the other knob assembly to rotate.

[0016] The second linkage part has a matching surface for matching with the knob assembly. In the case that the two second linkage parts are arranged on different sides of the first linkage part in the width direction of the first linkage part, the matching surfaces of the two second linkage parts face opposite directions. In the case that one knob assembly is rotated in a clockwise direction, the other knob assembly will rotate in a counterclockwise direction under the drive of the linkage. In this solution, when different knob assemblies are rotated in the same direction, the switch gear of any knob assembly is increased. Therefore, when one of the two adjacent knob assemblies is rotated in a clockwise direction (the gear is increased), the other knob assembly is rotated in a counterclockwise direction (the gear is decreased), thereby realizing the function of increasing the gear of one knob assembly and decreasing the gear of the other knob assembly, and avoiding the problem of excessively high operating power of the cooking equipment.

[0017] In some technical solutions, the two second linkage parts arranged at the two ends of the first linkage part are located on the same side of the first linkage part, and the knob assembly has a plurality of switch gears, and when the two adjacent knob assemblies are rotated in the first direction, the switch gear of one knob assembly is increased, and the switch gear of the other knob assembly is decreased.

[0018] The second linkage part has a matching surface for matching with the knob assembly. In the case that the two second linkage parts are arranged on the same side of the first linkage part in the width direction of the first linkage part, the matching surfaces of the two second linkage parts face the same direction. In the case that one knob assembly is rotated in a clockwise direction, the other knob assembly will also rotate in a clockwise direction under the drive of the linkage. In this solution, when the two adjacent knob assemblies are rotated in the same direction, the gear of one knob assembly is increased, and the gear of the other knob assembly is decreased. Therefore, when one of the two adjacent knob assemblies is rotated in a clockwise direction (the gear is increased), the other knob assembly is also rotated in a clockwise direction (the gear is decreased), thereby realizing the function of increasing the gear of one knob assembly and decreasing the gear of the other knob assembly, and avoiding the problem of excessively high operating power of the cooking equipment.

[0019] In some embodiments, the two second linkage parts arranged at the two ends of the first linkage part are located at the same side of the first linkage part; the switch assembly further comprises a transmission member, one of the two adjacent knob assemblies is connected with the second linkage part through the transmission member, so that the two adjacent knob assemblies can rotate in opposite directions; the knob assembly has a plurality of switch gears, and the switch gears of the knob assembly increase when any knob assembly is rotated in the first direction.

[0020] The second linkage part has a matching surface for matching with the knob assembly. In the case that the two second linkage parts are arranged at the same side of the first linkage part along the width direction of the first linkage part, the matching surfaces of the two second linkage parts face the same direction.

[0021] In the case that no transmission member is arranged, the two knob assemblies rotate in the same direction under the driving of the linkage member. In this embodiment, one of the two adjacent knob assemblies is connected with the linkage member through the transmission member. In the case that one knob assembly is rotated in the clockwise direction, the linkage member moves relative to the knob assembly, and the knob assembly drives the other knob assembly to rotate through the transmission member. The transmission member can change the transmission direction, so that the two adjacent knob assemblies rotate in opposite directions. In this embodiment, when different knob assemblies are rotated in the same direction, the switch gears of any knob assembly increase. Therefore, when one of the two adjacent knob assemblies rotates in the clockwise direction (the gears increase), the other knob assembly also rotates in the clockwise direction (the gears decrease), so as to realize the function that one knob assembly increases the gears and the other knob assembly decreases the gears, and avoid the problem that the operating power of the cooking equipment is too high.

[0022] In some embodiments, the switch assembly further comprises a reinforcing part arranged on the second linkage part, and the reinforcing part is located at the side of the second linkage part away from the knob assembly.

[0023] Since the width of the second linkage part is smaller than the width of the first linkage part, the structural strength of the second linkage part is smaller than that of the first linkage part. In this embodiment, the reinforcing part is arranged on the second linkage part to improve the structural strength of the second linkage part, so as to prevent the second linkage part from moving away from the knob assembly due to stress, and ensure that the second linkage part can stably match with the knob assembly. The reinforcing part is arranged at the side of the second linkage part away from the knob assembly, so as to avoid the interference of the reinforcing part with the matching position of the second linkage part and the knob assembly.

[0024] In some embodiments, the angle between the side of the first linkage part in the length direction and the second linkage part is α, and α>90°.

[0025] The first linkage part has an included angle with the second linkage part in the length direction, and the included angle is an obtuse angle. In the case that the second linkage part is forced, the obtuse angle structure makes the force of the first linkage part and the second linkage part at the connection position dispersed to a wider area, reduces the risk of the second linkage part bending relative to the first linkage part, and ensures that the second linkage part can stably cooperate with the knob assembly.

[0026] In some technical solutions, the second linkage part is provided with a cooperation part extending along the length direction of the second linkage part, and the cooperation part extends to the connection position of the first linkage part and the second linkage part.

[0027] The cooperation part extends to the connection position of the first linkage part and the second linkage part, so that a longer cooperation part can be arranged on the second linkage part as much as possible. During the movement of the linkage, the second linkage part can stably cooperate with the knob assembly with a longer cooperation length.

[0028] In some technical solutions, the knob assembly comprises a knob provided with a protruding part, and the knob has a free state and a linkage state; a rotating part provided with a guide groove, the protruding part is inserted into the guide groove, and the protruding part can slide in the guide groove; in the free state, the knob can rotate relative to the rotating part; in the linkage state, the knob can drive the rotating part to rotate through the protruding part; and the rotating parts in adjacent two knob assemblies are linked through the linkage.

[0029] The user can rotate the knob, change the gear of the knob assembly by rotating the knob, and make the cooking area corresponding to the knob assembly realize the heating function with different power. The knob is provided with a protruding part, the protruding part is inserted into the guide groove on the rotating part, and when the protruding part and the inner wall of the guide groove are linked, the knob is in the linkage state, and the knob can drive the rotating part to rotate. When the protruding part and the inner wall of the guide groove are not linked, the knob is in the free state, and the knob will not drive the rotating part to rotate during the rotation process.

[0030] During the rotation of the knob by the user, when the protruding part and the inner wall of the guide groove are linked, the knob can drive the rotating part to rotate, the rotating part cooperates with the linkage, thereby driving the rotating part of another knob assembly to rotate, and when the rotating part and the knob in the another knob assembly are linked, the gear linkage of the adjacent two knob assemblies is realized.

[0031] In the adjacent two knob assemblies, if the rotating part and the knob in one of the knob assemblies are not linked, the gear linkage of the adjacent two knob assemblies will not be generated. Therefore, the cooperation design of the protruding part and the guide groove makes the switch assembly have different functions of gear linkage and gear free adjustment, and improves the functionality of the switch assembly.

[0032] In some technical solutions, the matching part is a rack, and the knob assembly comprises a gear, and the rack is engaged with the gear.

[0033] When the gear rotates, the gear can drive the rack to move, so that the rack can drive the gear in the other knob assembly to rotate, thereby realizing linkage of the two gears.

[0034] In the second aspect, the utility model provides a kind of cooking equipment, comprising: the switch component as in the first aspect.

[0035] In some technical solutions, the cooking equipment comprises at least two heating assemblies, and the switch gear of one knob assembly is associated with the operating power of one heating assembly;The cooking equipment has maximum heating power W, and the sum of operating power of at least two heating assemblies is less than or equal to maximum heating power W.

[0036] The cooking equipment usually has maximum heating power, in the case of multiple heating partitions being provided on the cooking equipment, if the heating power of the heating assembly corresponding to each heating partition is not limited, the sum of heating power of multiple heating assemblies will be greater than maximum heating power. Or, if the maximum power allowed to operate of each heating assembly is set to be small, it will lead to low heating efficiency of the cooking accessory for each heating partition, for example, the maximum heating power of the cooking equipment is 2000W, in the case of two heating partitions, the maximum power allowed to operate of each heating partition is set to 1000W, the above-mentioned mode limits the heating efficiency, and the waiting time of user in the cooking process is long.

[0037] In the present technical solution, when the gear of one knob assembly increases, the heating power of the corresponding heating assembly will also increase, if the sum of power of at least two heating assemblies does not reach maximum heating power, then the gear linkage of adjacent two knob assemblies will not occur, and the gear change of one knob assembly will not affect the gear change of other knob assemblies. If the sum of power of at least two heating assemblies reaches maximum heating power, and the gear of one knob assembly continues to increase, the sum of power of at least two heating assemblies will exceed maximum heating power, in order to avoid the above-mentioned situation, the gear of other knob assemblies needs to be adjusted downward, thereby reducing the heating power of other heating assemblies.

[0038] The gear linkage is realized through the at least two knob assemblies, so that the gears of part of the knob assemblies can be automatically adjusted when the cooking device is about to overload. In this way, the sum of the powers of the at least two heating assemblies can be prevented from exceeding the maximum heating power, and the user does not need to worry about the problem of overloading operation of the cooking device when using any knob assembly, only needs to adjust the gears of the heating assemblies according to the user's cooking demand, provides convenience for the user's cooking process, and is helpful to improve the user's experience of using the cooking device.

[0039] In some technical solutions, optionally, the knobs in the adjacent two knob assemblies are set as a first knob and a second knob, the at least two heating assemblies include a first heating assembly and a second heating assembly, the gears of the first knob and the second knob are respectively associated with the operating powers of the first heating assembly and the second heating assembly; the operating power of the first heating assembly is P1 when the first knob is at the set gear, the operating power of the first heating assembly is P0 when the first knob is at the maximum gear, and P2=P0-P1; the second knob is in a free state when the operating power of the second heating assembly is less than P2 when the first knob is at the set gear.

[0040] In the at least two knob assemblies, each knob has a maximum gear, and the operating power of the heating assembly corresponding to the maximum gear is P0, which is less than or equal to the maximum heating power W of the cooking device.

[0041] In the adjacent two knob assemblies, the heating power of the first knob corresponding to a gear of the first knob is P1, and the difference between the heating power corresponding to the gear of the first knob at this time and the maximum gear is P2 (P0-P1). When the second knob is rotated, the second knob will not drive the rotating member to rotate in the process of rotation when the heating power corresponding to the gear of the second knob does not reach P2, and the second knob is in a free state at this time.

[0042] In some technical solutions, optionally, P3=W-P0, and the gear of the first knob remains unchanged in the process of adjusting the gear of the second knob when the operating power of the first heating assembly is less than or equal to P3.

[0043] The maximum heating power of the cooking device is W, the heating power corresponding to the maximum gear of the knob is P0, and the difference between W and P0 is P3. If the heating power corresponding to the first knob is less than or equal to P3, the sum of the corresponding heating powers of the first knob and the second knob will not exceed the maximum heating power W even if the second knob operates at the maximum gear in this process, and the adjustment of the gear of the second knob will not link the first knob, so that the first knob is in a free state.

[0044] In some technical solutions, optionally, in a case where the operating power of the first heating assembly is greater than P3, during the increasing of the switch gear of the second knob, the gear of the first knob can change with the second knob.

[0045] If the heating power corresponding to the first knob is greater than P3, during the adjustment of the gear of the second knob, the sum of the heating power corresponding to the first knob and the second knob has the possibility of exceeding the maximum heating power, therefore, when the sum of the power of the first knob and the second knob reaches the maximum heating power, and the gear of the second knob continues to increase, it is necessary to link the first knob to decrease the gear.

DETAILED DESCRIPTION

[0065] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model will be further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0066] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from those described herein, therefore, the protection scope of the utility model is not limited by the specific embodiments disclosed below.

[0067] The following refers to Figures 1 to 15 The switch assembly and the cooking equipment provided according to some embodiments of the utility model are described.

[0068] In combination Figure 1 , Figure 2 and Figure 3 , in some embodiments of the utility model, a switch assembly 100 is provided, the switch assembly 100 includes: knob assembly 110 and linkage 120, linkage 120 is connected to two adjacent knob assemblies 110, the number of knob assembly 110 is at least two, two adjacent knob assemblies 110 are linked to each other through linkage 120, linkage 120 includes first linkage part 121 and second linkage part 122, second linkage part 122 is arranged at both ends of first linkage part 121, second linkage part 122 is used for cooperating with knob assembly 110 and is linked, on the length direction of first linkage part 121 (the arrow at H2 in the length direction of first linkage part 121 is used to express) Figure 3 , the part of first linkage part 121 is oppositely arranged with second linkage part 122, and the other part of first linkage part 121 is oppositely arranged with knob assembly 110.

[0069] In the case where the cooking equipment has multiple cooking zones, one knob assembly 110 can adjust the heating power of one cooking zone. Linkage 120 is used to link at least two knob assemblies 110, when one knob assembly 110 rotates, the remaining knob assemblies 110 can also rotate under the drive of linkage 120, so as to realize the gear linkage of multiple knob assemblies 110, that is, when the gear of one knob assembly 110 is adjusted, the gears of other knob assemblies 110 can also be adjusted accordingly, when the user uses multiple cooking zones of the cooking equipment at the same time, it is not necessary to adjust the gears of multiple knob assemblies 110 in sequence, which provides convenience for the user to use the cooking equipment.

[0070] The linkage 120 comprises a first linkage portion 121 and a second linkage portion 122, and the second linkage portion 122 is arranged at both ends of the first linkage portion 121 respectively, one second linkage portion 122 is used in cooperation with one knob assembly 110, so that one knob assembly 110 is linked with the adjacent knob assembly 110 through the first linkage portion 121 and the second linkage portion 122. In the length direction of the first linkage portion 121, one part of the first linkage portion 121 is opposite to the second linkage portion 122, and the other part of the first linkage portion 121 is distributed in a staggered manner with the second linkage portion 122, that is, the other part of the first linkage portion 121 is not provided with the second linkage portion 122 corresponding, on this basis, the knob assembly 110 can be arranged opposite to the other part of the first linkage portion 121, so as to be arranged on one side of the first linkage portion 121 in the length direction. In the width direction of the knob assembly 110, the knob assembly 110 does not protrude out of the first linkage portion 121, or only a part of the knob assembly 110 protrudes out of the first linkage portion 121. By arranging the knob assembly 110 in the length direction of the linkage 120, the space occupied by the knob assembly 110 in the width direction of the first linkage portion 121 can be reduced, so as to reduce the overall width of the switch assembly 100, reduce the volume of the switch assembly 100, and further facilitate reducing the occupied space of the switch assembly 100 in the cooking equipment, and provide convenience for the user to use the cooking equipment.

[0071] As shown in Figure 3 some embodiments, optionally, the width of the first linkage portion 121 is greater than the width of the second linkage portion 122. Figure 3 The arrow at H1 in the width direction of the first linkage portion 121 and the second linkage portion 122.

[0072] The width of the first linkage portion 121 is larger, and at the end of the first linkage portion 121, the first linkage portion 121 can leave enough space to arrange the knob assembly 110 in the width direction, and along the width direction of the first linkage portion 121, it is ensured that the knob assembly 110 does not protrude out of the first linkage portion 121, or only a part of the knob assembly 110 protrudes out of the first linkage portion 121.

[0073] As shown in Figure 4 , Figure 5 and Figure 6 some embodiments, optionally, along the width direction of the first linkage portion 121, the second linkage portion 122 is located at the side of the first linkage portion 121, and the second linkage portions 122 arranged at both ends of the first linkage portion 121 are located at the same side or different sides of the first linkage portion 121.

[0074] The second linkage part 122 is disposed at the end of the first linkage part 121, and the second linkage part 122 is disposed on the side of the first linkage part 121 along the width direction, thereby providing more clearance space for the knob assembly 110.

[0075] In this case, all the knob assemblies 110 can be arranged along the length of the first linkage portion 121, so that the knob assemblies 110 do not protrude from the first linkage portion 121 along the width of the first linkage portion 121. Alternatively, most of the knob assemblies 110 can be arranged along the length of the first linkage portion 121, and a small portion of the knob assemblies 110 can protrude from the first linkage portion 121 along the width of the first linkage portion 121.

[0076] In the width direction of the first linkage part 121, two adjacent knob assemblies 110 can be disposed on the first side of the first linkage part 121, or one of the two adjacent knob assemblies 110 can be disposed on the first side of the first linkage part 121 and the other can be disposed on the second side of the first linkage part 121.

[0077] like Figure 4 As shown, in some embodiments, optionally, two second linkage portions 122 disposed at both ends of the first linkage portion 121 are located on different sides of the first linkage portion 121, and the knob assembly 110 has multiple switch positions along the first direction ( Figure 4 The arrow at H3 could also point to... Figure 4 When any knob assembly 110 is rotated (in the opposite direction of the arrow at H3), the switch position of the knob assembly 110 increases.

[0078] When a user rotates one knob assembly 110, the knob assembly 110 will drive the linkage 120 to move during the rotation, so that the linkage 120 drives the other knob assembly 110 to rotate.

[0079] The second linkage part 122 has a mating surface for engaging with the knob assembly 110. When the two second linkage parts 122 are located on different sides of the first linkage part 121 along its width, the mating surfaces of the two second linkage parts 122 face opposite directions. When one knob assembly 110 is rotated clockwise, the other knob assembly 110 will rotate counterclockwise under the influence of the linkage member 120. Furthermore, in this design, when different knob assemblies 110 are rotated in the same direction, the switching position of each knob assembly 110 increases. Therefore, when one of two adjacent knob assemblies 110 rotates clockwise (increasing the position), the other knob assembly 110 rotates counterclockwise (decreasing the position), thus achieving the function of one adjacent knob assembly 110 increasing the position and the other decreasing it, preventing the cooking equipment from operating at excessive power.

[0080] In combination Figure 4 And Figure 5 As shown in FIG. 1, in some embodiments, the two second linkage parts 122 arranged at the two ends of the first linkage part 121 are located at the same side of the first linkage part 121, the knob assembly 110 has multiple switch gears, and when the adjacent two knob assemblies 110 are rotated in the first direction, the gear of one knob assembly 110 is increased, and the gear of the other knob assembly 110 is decreased.

[0081] The second linkage part 122 has a matching surface for matching with the knob assembly 110. In the case that the two second linkage parts 122 are arranged at the same side of the first linkage part 121 along the width direction of the first linkage part 121, the matching surfaces of the two second linkage parts 122 face the same direction. In the case that one knob assembly 110 is rotated in the clockwise direction, the other knob assembly 110 will also rotate in the clockwise direction under the driving of the linkage 120. In this scheme, when the adjacent two knob assemblies 110 are rotated in the same direction, the gear of one knob assembly 110 is increased, and the gear of the other knob assembly 110 is decreased. Therefore, when one of the adjacent two knob assemblies 110 rotates in the clockwise direction (the gear is increased), the other knob assembly 110 also rotates in the clockwise direction (the gear is decreased), so as to realize the function that one knob assembly is increased, and the other knob assembly is decreased, and avoid the problem that the running power of the cooking equipment is too high.

[0082] In combination Figure 4 And Figure 6 As shown in FIG. 1, in some embodiments, the two second linkage parts 122 arranged at the two ends of the first linkage part 121 are located at the same side of the first linkage part 121. The switch assembly 100 further comprises a transmission part 130, one of the adjacent two knob assemblies 110 is linked with the second linkage part 122 through the transmission part 130, so that the adjacent two knob assemblies 110 can rotate in the opposite direction, the knob assembly 110 has multiple switch gears, and when any knob assembly 110 is rotated in the first direction, the gear of the knob assembly 110 is increased.

[0083] The second linkage part 122 has a matching surface for matching with the knob assembly 110. In the case that the two second linkage parts 122 are arranged at the same side of the first linkage part 121 along the width direction of the first linkage part 121, the matching surfaces of the two second linkage parts 122 face the same direction.

[0084] In the absence of the transmission member 130, the two knob assemblies 110 rotate in the same direction under the drive of the linkage member 120. In the present scheme, one knob assembly 110 of the two adjacent knob assemblies 110 cooperates with the linkage member 120 through the transmission member 130. In the case that one knob assembly 110 rotates in the clockwise direction, the linkage member 120 moves relative to the knob assembly 110, and the knob assembly 110 drives the other knob assembly 110 to rotate through the transmission member 130. The transmission member 130 can change the transmission direction, so that the two adjacent knob assemblies 110 rotate in opposite directions. In the present scheme, when the different knob assemblies 110 are rotated in the same direction, the switch gear position of any knob assembly 110 is increased. Therefore, when one of the two adjacent knob assemblies 110 rotates in the clockwise direction (the gear position is increased), the other knob assembly 110 also rotates in the clockwise direction (the gear position is decreased), so as to realize the function that one knob assembly increases the gear position and the other knob assembly decreases the gear position, and avoid the problem that the operating power of the cooking equipment is too high.

[0085] As shown in Figure 3 In some embodiments, the switch assembly 100 optionally further comprises a reinforcing portion 140, which is arranged on the second linkage portion 122 and located on the side of the second linkage portion 122 away from the knob assembly 110.

[0086] Since the width of the second linkage portion 122 is smaller than the width of the first linkage portion 121, the structural strength of the second linkage portion 122 is smaller than the structural strength of the first linkage portion 121. In the present scheme, the reinforcing portion 140 is arranged on the second linkage portion 122 to improve the structural strength of the second linkage portion 122, so as to avoid that the second linkage portion 122 moves away from the knob assembly 110 due to force, and ensure that the second linkage portion 122 can stably cooperate with the knob assembly 110. The reinforcing portion 140 is arranged on the side of the second linkage portion 122 away from the knob assembly 110, so as to avoid that the reinforcing portion 140 interferes with the cooperation position of the second linkage portion 122 and the knob assembly 110.

[0087] The reinforcing portion 140 can be the same material as the linkage member 120, and the reinforcing portion 140 is directly and integrally formed on the second linkage portion 122 to increase the local thickness of the second linkage portion 122.

[0088] As shown in Figure 3 In some embodiments, the first linkage portion 121 and the second linkage portion 122 are arranged at an angle α in the length direction, and α>90°.

[0089] The first linkage 121 has an angle between its side and the second linkage 122 along its length, and the angle is obtuse. When the second linkage 122 is subjected to force, the obtuse angle structure distributes the force on the first linkage 121 and the second linkage 122 at the connection position to a wider area, reducing the risk of the second linkage 122 bending relative to the first linkage 121 and ensuring that the second linkage 122 can stably cooperate with the knob assembly 110.

[0090] For example, α is 100°, 110° or 120°.

[0091] Combination Figure 1 and Figure 2 As shown, in some embodiments, the second linkage part 122 is provided with a mating part 124, which extends along the length direction of the second linkage part 122 and extends to the connection between the first linkage part 121 and the second linkage part 122.

[0092] The mating part 124 extends to the connection between the first linkage part 121 and the second linkage part 122, so that the mating part 124 can be arranged as long as possible on the second linkage part 122. During the movement of the linkage 120, the second linkage part 122 can stably have a long mating length with the knob assembly 110.

[0093] Combination Figure 2 , Figure 7 , Figure 11 and Figure 12 As shown, in some embodiments, optionally, the knob assembly 110 includes a knob 111 and a rotating member 113. The knob 111 has a protrusion 112 and has a free state and a linked state. The rotating member 113 has a guide groove 114, and the protrusion 112 is inserted into the guide groove 114. The protrusion 112 can slide in the guide groove 114. In the free state, the knob 111 can rotate relative to the rotating member 113. In the linked state, the knob 111 can drive the rotating member 113 to rotate through the protrusion 112. The rotating members 113 in two adjacent knob assemblies 110 are linked together through the linkage 120.

[0094] Users can rotate knob 111 to change the settings of knob assembly 110, allowing the corresponding cooking zone to heat at different power levels. Knob 111 has a protrusion 112 that inserts into a guide groove 114 on rotating component 113. When the protrusion 112 and the inner wall of the guide groove 114 are in linkage, knob 111 is in a linked state, driving rotating component 113 to rotate. When the protrusion 112 and the inner wall of the guide groove 114 are not in linkage, knob 111 is in a free state, and during rotation, knob 111 will not drive rotating component 113 to rotate.

[0095] When the user rotates the knob 111, when the inner wall of the protrusion 112 and the guide groove 114 are linked, the knob 111 can drive the rotating part 113 to rotate. The rotating part 113 cooperates with the linkage part 120, thereby driving the rotating part 113 of another knob assembly 110 to rotate. When the rotating part 113 in the other knob assembly 110 is linked with the knob 111, the gear linkage of the two adjacent knob assemblies 110 is realized.

[0096] In two adjacent knob assemblies 110, if the rotating element 113 and the knob 111 in one of the knob assemblies 110 do not move together, the two adjacent knob assemblies 110 will not move together. Therefore, the cooperative design of the protrusion 112 and the guide groove 114 enables the switch assembly 100 to have different functions of moving together and freely adjusting the gear, thereby improving the functionality of the switch assembly 100.

[0097] For example, the rotating element 113 can be a gear or a sprocket.

[0098] Combination Figure 2 , Figure 7 , Figure 11 and Figure 12 As shown, in some embodiments, the guide groove 114 optionally includes a first groove end 1141 and a second groove end 1142. In the linked state, the protrusion 112 contacts the first groove end 1141 or the second groove end 1142. In the free state, the protrusion 112 separates from the first groove end 1141 and the second groove end 1142.

[0099] During the rotation of knob 111, protrusion 112 can slide in guide groove 114. When protrusion 112 does not contact the two ends of guide groove 114, protrusion 112 will not push rotating member 113. Therefore, knob 111 can rotate relative to rotating member 113. At this time, rotating member 113 will not rotate with knob 111.

[0100] When the protruding part 112 contacts the end of the guide groove 114, if the knob 111 continues to rotate, the protruding part 112 will push the end of the guide groove 114, so that the rotating part 113 can rotate with the knob 111. The rotating part 113 in one knob assembly 110 can link the rotating part 113 in the other knob assembly 110, and when the protruding part 112 in the other knob assembly 110 contacts the end of the guide groove 114, the gears of the two knob assemblies 110 can be linked.

[0101] Of course, in other embodiments, a protruding structure can also be arranged in the guide groove 114, which is used to cooperate with the protruding part 112, that is, the protruding part 112 does not need to contact the end of the guide groove 114, and when the protruding part 112 contacts the protruding structure, the protruding part 112 can push the rotating part 113.

[0102] In some embodiments, optionally, the central angle between the first groove end 1141 and the second groove end 1142 is α1, and the central angle of the knob 111 rotating from the minimum gear to the maximum gear is α2, and α1>α2.

[0103] The corresponding central angles of the two ends of the guide groove 114 are α1, and the circle formed by the maximum gear difference of the knob 111 is α2, and α1>α2.

[0104] For a cooking device with at least two knob assemblies 110, generally at least two heating assemblies 200, one knob assembly 110 is used to control one heating assembly 200. In order to avoid the sum of the heating powers of the at least two heating assemblies 200 exceeding the maximum heating power of the cooking device, at least two knob assemblies 110 need to be linked. When rotating one knob 111, the sum of the operating powers of the at least two heating assemblies 200 will exceed the maximum heating power, so the gears of the other knobs 111 need to be reduced, so as to reduce the heating power of the other heating assemblies 200.

[0105] During the process of the user rotating the knob 111 to reduce the gear, the sum of the heating powers of the at least two heating assemblies 200 will not exceed the maximum heating power, so when reducing the gear of one knob 111, the linkage with the other knobs 111 is not needed, and in the present scheme, α1>α2 is limited, and during the process of reducing the gear of the knob 111, the knob 111 rotates relative to the rotating part 113, that is, even if the knob 111 rotates from the maximum gear to the minimum gear, the knob 111 will not push the rotating part 113.

[0106] In other embodiments, α1=α2 can also be arranged.

[0107] In combination Figure 2 , Figure 7 ,Figure 11 and Figure 12 As shown, in some embodiments, optionally, the rotating member 113 is provided with a shaft hole 1131, the shaft hole 1131 is connected to the guide groove 114, and the knob 111 is inserted into the shaft hole 1131.

[0108] The rotating part 113 has a shaft hole 1131, and the knob 111 can be inserted into the shaft hole 1131. The protrusion 112 is provided on the knob 111. Therefore, by connecting the shaft hole 1131 with the guide groove 114, the protrusion 112 can extend out of the shaft hole 1131, so that the protrusion 112 and the guide groove 114 can cooperate.

[0109] Combination Figure 2 , Figure 7 , Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, optionally, the knob 111 includes: a position switch 1113, a rotating shaft 1114, and a knob body 1117. The position switch 1113 has multiple switching positions. The rotating shaft 1114 is connected to the position switch 1113 and is used to drive the position switch 1113 to adjust the switching position. In the radial section of the rotating shaft 1114, the section includes an arc-shaped segment 1115 and a driving segment 1116. The knob body 1117 is inserted into the rotating shaft 1114. The arc-shaped segment 1115 is used to make the rotating shaft 1114 and the knob body 1117 rotate concentrically, and the driving segment 1116 is used to make the rotating shaft 1114 rotate synchronously with the knob body 1117.

[0110] The user can rotate the knob body 1117. The knob body 1117 is connected to the rotating shaft 1114, and the rotating shaft 1114 can rotate synchronously with the knob body 1117. When the rotating shaft 1114 rotates, it can drive the gear switch 1113 to adjust the gear.

[0111] In the radial section of the rotating shaft 1114, at least two parts of the section have different profiles. At least one part of the profile is arc-shaped, and the arc-shaped segment 1115 is concentrically arranged with the knob body 1117, allowing the rotating shaft 1114 and the knob body 1117 to rotate concentrically. The other part of the profile serves as the driving segment 1116. The driving segment 1116 can be a straight structure, which circumferentially limits the knob body 1117, allowing the rotating shaft 1114 and the knob body 1117 to rotate synchronously. Of course, the driving segment 1116 can also be other shapes. For example, the driving segment 1116 can be an arc-shaped structure, but the curvature of the driving segment 1116 is smaller than that of the arc-shaped segment 1115. Alternatively, the driving segment 1116 can also be a wave-shaped or other structures.

[0112] In the embodiment, the D-shaped structure is adopted between the rotating shaft 1114 and the knob body 1117 for limiting, so as to ensure that the knob body 1117 does not slip with the rotating shaft 1114.

[0113] The gear switch 1113 in the embodiment has the same working principle as the gear switch 1113 in the related art, and details are not repeated here.

[0114] In combination with FIGS. 11A and 11B, Figure 12 and Figure 13 In some embodiments, the gear switch 1113 is provided with an output shaft 1118, the rotating shaft 1114 is provided with a plug-in hole 1119, the output shaft 1118 is plugged into the plug-in hole 1119, and the plug-in hole 1119 is provided with a reinforcing rib 1120 extending along the axial direction of the rotating shaft 1114.

[0115] The plug-in hole 1119 is arranged on the rotating shaft 1114 and extends along the axial direction of the rotating shaft 1114, the output shaft 1118 is arranged on the gear switch 1113 and is plugged into the plug-in hole 1119, and the rotating shaft 1114 drives the output shaft 1118 to rotate synchronously, so as to adjust the gear of the gear switch 1113. Since the rotating shaft 1114 is provided with a hole, the structural strength of the rotating shaft 1114 is reduced, and in the present scheme, the reinforcing rib 1120 is arranged in the plug-in hole, which is used to enhance the structural strength of the rotating shaft 1114, avoid deformation of the rotating shaft 1114, and ensure that the rotating shaft 1114 stably cooperates with the knob body 1117 and the output shaft 1118.

[0116] In other embodiments, the reinforcing rib 1120 can also have other distribution modes, for example, being distributed in a cross mode on the inner wall of the plug-in hole 1119.

[0117] As shown in FIGS. 11A and 11B, Figure 7 In some embodiments, along the circumferential direction of the rotating shaft 1114, the first side (the position indicated by a in FIG. 11B) of the protruding part 112 is used to push the rotating part 113, and the second side (the position indicated by b in FIG. 11B) of the protruding part 112 has an included angle with the first side of the protruding part 112. Figure 7 Figure 7

[0118] ​​The first side of the protruding part 112 is used to push the rotating part 113, that is, the first side of the protruding part 112 can abut against one end of the guide groove 114 to push the inner wall of the guide groove 114. Exemplarily, the first side of the protruding part 112 extends along the radial direction of the rotating shaft 1114, and the second side of the protruding part 112 does not extend along the radial direction of the rotating shaft 1114 due to the included angle between the first side and the second side of the protruding part 112. In this case, the head of the protruding part 112 is narrower, and the bottom of the protruding part 112 is wider, which is beneficial to increase the contact area of the protruding part 112 and the rotating shaft 1114, thereby improving the connection stability of the protruding part 112 and the rotating shaft 1114.

[0119] In combination with Figure 1 , Figure 2 and Figure 11 , in some embodiments, the matching part 124 is a rack 123, and the knob assembly 110 includes a gear 115, and the rack 123 is engaged with the gear 115.

[0120] When the gear 115 rotates, the gear 115 can drive the rack 123 to move, so that the rack 123 can drive the gear 115 in another knob assembly 110 to rotate, thereby realizing the linkage of the two gears 115.

[0121] Of course, in other embodiments, the matching part 124 can also be a chain, and the knob assembly 110 includes a sprocket.

[0122] The switch assembly 100 further includes a base 150, and the knob assembly 110 and the linkage 120 are installed on the base 150.

[0123] In some embodiments of the utility model, a cooking equipment is provided, which includes the switch assembly 100 in any of the above embodiments and can achieve the same technical effects, which will not be described here.

[0124] As shown in Figure 15 , in some embodiments, optionally, the cooking equipment includes at least two heating assemblies 200 (in other embodiments, the heating assembly 200 is not limited to the structure shown in Figure 15 ), and the switch gear position of one knob assembly 110 is associated with the operating power of one heating assembly 200. The cooking equipment has a maximum heating power W, and the sum of the operating powers of the at least two heating assemblies 200 is less than or equal to the maximum heating power W.

[0125] The cooking device usually has a maximum heating power. In the case that multiple heating zones are provided on the cooking device, if the heating power of each heating assembly 200 corresponding to the heating zone is not limited, the sum of the heating power of multiple heating assemblies 200 may be greater than the maximum heating power. Or, if the maximum power allowed to run of each heating assembly 200 is set to be small, the heating efficiency of each heating zone on the cooking accessory will be low, for example, the maximum heating power of the cooking device is 2000W, and in the case that the heating zone is two, the maximum power allowed to run of each heating zone is set to be 1000W, the above-mentioned manner limits the heating efficiency, and the waiting time of the user in the cooking process is long.

[0126] In the embodiment, when the gear of one knob assembly 110 is increased, the heating power of the corresponding heating assembly 200 is also increased. If the sum of the power of at least two heating assemblies 200 does not reach the maximum heating power, the gears of adjacent two knob assemblies 110 will not be linked, and the gear change of one knob assembly 110 will not affect the gear change of the other knob assembly 110. If the sum of the power of at least two heating assemblies 200 reaches the maximum heating power, and the gear of one knob assembly 110 continues to increase, the sum of the power of at least two heating assemblies 200 will exceed the maximum heating power. In order to avoid the above-mentioned situation, the gears of the other knob assemblies 110 need to be adjusted downward, so as to reduce the heating power of the other heating assemblies 200.

[0127] The gear linkage of at least two knob assemblies 110 can automatically adjust the gears of part of the knob assemblies 110 when the cooking device is about to overload. Through the above-mentioned manner, the sum of the power of at least two heating assemblies 200 can be prevented from exceeding the maximum heating power. When the user uses any knob assembly 110, the user does not need to worry about the problem of overloading operation of the cooking device. The user only needs to adjust the gears of the heating assemblies 200 according to the user's cooking needs, which provides convenience for the user's cooking process and is helpful to improve the user's experience of using the cooking device.

[0128] The heating assembly 200 can be a heating pipe or a heating wire.

[0129] In the related art, for the cooking device with multiple zones, the maximum power of the left and right cooking zones can only be 1000W (the total power exceeding 2000W will damage the circuit). In the embodiment, the linkage mechanical knob 111 structure is adopted, which breaks the limitation that the maximum power of the traditional knob 111 on the left and right can only be 1000W.

[0130] In combination with Figure 14 and Figure 15As shown, in some embodiments, optionally, the knobs 111 in two adjacent knob assemblies 110 are designated as a first knob 1111 and a second knob 1112, respectively. At least two heating assemblies 200 include a first heating assembly 210 and a second heating assembly 220. The settings of the first knob 1111 and the second knob 1112 are respectively associated with the operating power of the first heating assembly 210 and the second heating assembly 220. When the first knob 1111 is in its set setting, the operating power of the first heating assembly 210 is P1. When the first knob 1111 is in its maximum setting, the operating power of the first heating assembly 210 is P0, and P2 = P0 - P1. When the first knob 1111 is in its set setting, and the operating power of the second heating assembly 220 is less than P2, the second knob 1112 is in a free state.

[0131] In at least two knob assemblies 110, each knob 111 has a maximum setting, and the operating power of the heating assembly 200 corresponding to the maximum setting is P0, which is less than or equal to the maximum heating power W of the cooking device.

[0132] In two adjacent knob assemblies 110, when the first knob 1111 is in a certain position, the heating power corresponding to the first knob 1111 is P1. The difference in heating power between the first knob 1111 at this position and the maximum position is P2 (P0-P1). When the second knob 1112 is rotated, if the heating power corresponding to the position of the second knob 1112 does not reach P2, the second knob 1112 will not drive the rotating component 113 to rotate during rotation, and the second knob 1112 is in a free state.

[0133] The control process of the cooking equipment is as follows: After the first knob 1111 increases the power, it is determined whether the sum of the power of the first heating element 210 and the second heating element 220 is about to exceed 2000W. If it exceeds 2000W, the second knob 1112 decreases the power. If it does not exceed 2000W, it operates normally.

[0134] For example, the knob 111 in this embodiment has four positions. Each 45° rotation of the knob 111 increases or decreases the position by one. The four positions are 0W (…). Figure 7 (as shown in the image), 500W ( Figure 8 (as shown in the image), 1000W ( Figure 9 (as shown in the image) and 1500W ( Figure 10 (The state shown in the figure). Of course, in other embodiments, the knob 111 is not limited to 4 positions, and the states of the positions are not limited to... Figures 7 to 10 The state shown.

[0135] Instructions for use:

[0136] First, the starting gears of the first knob 1111 and the second knob 1112 are gear 0.

[0137] Second, if the sum of the powers of the at least two heating assemblies 200 is less than or equal to 1500W, one of the knobs 111 increases or decreases a gear, and the other knob 111 does not rotate.

[0138] Third, the sum of the powers of the at least two heating assemblies 200 is equal to 2000W, and the two knob assemblies 110 and the linkage 120 are in a critical state.

[0139] Fourth, the sum of the powers of the at least two heating assemblies 200 is equal to 2000W, and one knob 111 increases a gear, and the linkage 120 drives the other knob 111 to decrease a gear.

[0140] The left and right knobs 111 are linked, and when the operating side increases a gear (the total power is about to exceed 2000W), the passive side will decrease a gear (to ensure that the adjusted power is less than or equal to 2000W). In this case, more gear options are given to the mechanical knob, and the total power does not exceed 2000W, ensuring the safety of the household appliance.

[0141] The gear space structure (the operating side decreases a gear, and the gear of the passive side remains unchanged) allows the linkage of the knobs 111 to have a gear space, and when the operating side decreases a gear, the passive side is not disturbed, which is beneficial to optimize the user experience and ensure that the total power is less than or equal to 2000W when the gears are increased or decreased at will.

[0142] In some embodiments, optionally, P3 is set as W-P0, and in the case that the operating power of the first heating assembly 210 is less than or equal to P3, the gear of the first knob 1111 remains unchanged during the gear adjustment of the second knob 1112.

[0143] The maximum heating power of the cooking device is W, and the heating power corresponding to the maximum gear of the knob 111 is P0. The difference between W and P0 is P3. If the heating power corresponding to the first knob 1111 is less than or equal to P3, even if the second knob 1112 operates at the maximum gear, the sum of the corresponding heating powers of the first knob 1111 and the second knob 1112 will not exceed the maximum heating power W. In this process, the adjustment of the gear of the second knob 1112 does not link the first knob 1111, and the first knob 1111 is in a free state.

[0144] In some embodiments, optionally, in the case that the operating power of the first heating assembly 210 is greater than P3, the gear of the first knob 1111 can change with the second knob 1112 during the increase of the switching gear of the second knob 1112.

[0145] If the heating power corresponding to the first knob 1111 is greater than P3, in the process of adjusting the gear of the second knob 1112, the sum of the heating power corresponding to the first knob 1111 and the second knob 1112 may exceed the maximum heating power, therefore, when the sum of the power of the first knob 1111 and the second knob 1112 reaches the maximum heating power, and the gear of the second knob 1112 continues to increase, it is necessary to link the first knob 1111 to reduce the gear.
