It should be noted that the touch is divided into a point touch and a continuous touch, and when the first contact 121 or the second contact 122 is touched, the controller 120 controls the heater 130 to decrease or increase the operating parameter of the heater 130 according to a preset value. Controller 120 controls heater 130 to continuously decrease or increase the operating parameter of heater 130 while first contact 121 or second contact 122 is continuously activated.

It should be noted that the distance between the first contact 121 and the second contact 122 may be set to be greater than or equal to 2mm and less than or equal to 20mm, and the distance is preferably 5mm to 15 mm.

Thus, the operating parameter of the heater 130 can be decreased or increased by rotating the operating end toggle lever 140 to the left to contact the first contact 121, or by rotating the toggle lever 140 to the right to contact the second contact 122 to increase or decrease the operating parameter of the heater 130.

Wherein, fig. 3 is an internal structure plan view of another cooking utensil (heating element not shown) that the embodiment of the utility model provides, fig. 4 is an enlarged schematic diagram of D portion structure in fig. 3, refer to fig. 3 and fig. 4, the second end of driving lever 140 is in casing 110 internal rotation setting, can set up driving lever 140's spacing post 112 in casing 110's holding cavity, driving lever 140's second end sets up pivot 143, rotate with spacing post 112 through pivot 143 and link to each other and realize driving lever 140 and set up in the rotation of casing.

For example, a rotation hole may be formed in one of the rotation shaft 143 and the position-limiting post 112, and then at least a portion of the other of the rotation shaft 143 and the position-limiting post 112 is disposed in the rotation hole, so that the shift lever 140 is rotatably disposed in the housing 110.

For example, a rotation hole is formed in the position-limiting column 112, and the rotation shaft 143 at the second end of the shift lever 140 is inserted into the rotation hole, so that the shift lever 140 is rotatably disposed in the housing 110, or for example, a rotation hole is formed in the rotation shaft 143 at the second end of the shift lever 140, and the position-limiting column 112 is inserted into the rotation hole, so that the shift lever 140 is rotatably disposed in the housing 110.

In some embodiments of the present invention, the limiting post 112 can be divided into an upper limiting post (not shown in the drawings) and a lower limiting post 1121 (see fig. 8), the upper limiting post is connected to the inner top surface of the casing 110, the lower limiting post 1121 is connected to the inner top surface of the casing 110, and it is easy to understand that the assembling stability of the driving lever 140 can be enhanced by clamping the driving lever 140 between the upper limiting post and the lower limiting post 1121.

It can be understood that, compared with the mode of setting an add-subtract key or a touch in a finger-stroke manner on the top surface of the housing 110, the mode of adjusting the size of the working parameter is realized by shifting the shift lever 140 from the side surface of the housing 110, so that the phenomena of key failure or key jumping and the like caused by water accumulation or soup on the top surface of the housing 110 can be avoided, a user can be prevented from being scalded by a pot or the spilled soup when the user operates on the top surface of the housing 110, and the assembly steps, the operation process and the like can be simplified.

Fig. 4 is an enlarged schematic view of a portion D in fig. 3, fig. 5 is a schematic view of a cross-sectional structure along a cutting line E in fig. 3, fig. 6 is an enlarged schematic view of a portion F in fig. 5, fig. 7 is a schematic view of a structure of a housing of a cooking appliance according to an embodiment of the present invention, and fig. 8 is an enlarged schematic view of a portion G in fig. 7.

Referring to fig. 2 to 8, the components and parts further include at least two elastic stoppers 150, the at least two elastic stoppers 150 are also respectively located at two sides of the shift lever 140, and the elastic stoppers 150 are used for driving the shift lever 140 to rotate in a reverse direction after the shift lever 140 rotates to contact with one of the contacts, so as to reset the shift lever 140.

The middle portion of the shift lever 140 passes through between the two elastic stoppers 150, and the elastic stoppers 150 allow the shift lever 140 to contact the first contact 121 or the second contact 122, and when the external force is removed, the shift lever 140 is driven to rotate in the opposite direction, so that the shift lever 140 is reset. The operating parameter is prevented from being excessively adjusted up or down due to the long-time contact between the shift lever 140 and the first contact 121 or the second contact 122, so that the operating parameter is inaccurately adjusted, and even the cooking appliance 100 is always in a state of increasing or decreasing the operating parameter, so that the machine body is damaged.

In order to make the end of the driving lever 140 outside the housing 110 have a resilient force capable of driving the driving lever 140 to return to the original position without any external force, it is possible to provide an elastic segment 151 on the elastic limiting member 150, and the elastic segment 151 gives an elastic force to the driving lever 140.

The elastic limiting member 150 may further include an abutting portion 152, and it is easily understood that if the shift lever 140 directly contacts the elastic portion 151, the shift lever 140 will wear the elastic portion 151 after a long time use, thereby affecting the resilience of the elastic portion 151. Therefore, the abutting section 152 can be connected with the elastic section 151, the elastic section 151 gives resilience force to the abutting section 152, and the abutting section 152 transmits the resilience force to the shift lever 140, so that the shift lever 140 is prevented from being in direct contact with the elastic section 151, and the shift lever 140 is prevented from damaging the elastic section 151 and influencing the resilience performance of the elastic section.

In some embodiments of the present invention, the elastic limiting member 150 may further have a supporting section 153, and the supporting section 153 may be used to support the elastic section 151 and the abutting section 152, and connect the elastic section 151 and the abutting section 152 with the housing 110, so as to improve the structural stability of the elastic limiting member 150.

Referring to fig. 4 or 8, in the present embodiment, the elastic limiting member 150 is an inverted "J" shape, and includes: an elastic segment 151, an abutting segment 152 and a supporting segment 153, and the elastic limiting member 150 is connected to the inner bottom surface of the housing 110 through one end of the supporting segment 153. The other end of the supporting section 153 is connected to one end of the elastic section 151, and the elastic section 151 is in an arc structure protruding toward the top end of the housing 110, so as to ensure that the elastic section 151 has sufficient resilience, and the driving lever 140 smoothly returns to the initial position after the operation is completed. The other end of the elastic segment 151 is connected to the abutting segment 152, and the other end of the abutting segment 152 is suspended toward the inner bottom surface of the housing 110.

The elastic segment 151, the abutting segment 152 and the supporting segment 153 cooperate to ensure the resilience of the shift lever 140, and prolong the service life of the elastic limiting member 150.

It should be noted that the elastic limiting member 150 may be disposed separately from the housing 110. And the shell 110 can be integrally formed, which is beneficial to batch production.

Further, an operation portion 144 may be provided at the first end of the lever 140, and one end of the operation portion 144 may extend toward the distal end of the housing 110. The operating part can provide an end which is easy to operate for a user, so that the usability of the cooking appliance is improved, and the user experience is improved.

Referring to fig. 6, in some embodiments of the present invention, the thickness of the end of the shifting lever 140 located in the housing 110 is a, and it can also be understood that the thickness of the cross section of the shifting lever 140 located between the two elastic locating parts 150 is a, and the value range of a is 2mm to 12mm, and it can be understood that the setting is such that, on one hand, it can ensure that the shifting lever 140 has a sufficient contact area with the abutting section 152 of the elastic locating part 150, and on the other hand, the blocking phenomenon of the shifting lever 140 can not occur, if the shifting lever 140 is located in the housing 110, the thickness of one end is too small, the shifting lever 140 is easily blocked into the arc structure of the elastic section 151 protruding toward the top end of the housing 110, and the blocking phenomenon of the shifting lever 140 occurs, so that the cooking utensil 100 is always in a state with increased or decreased working parameters, and even the phenomenon of organism damage occurs.

In order to prevent the shift lever 140 from directly contacting the elastic segment 151 of the elastic limiting member 150, it is effectively ensured that the shift lever 140 does not abut against the elastic segment 151 during operation, so that the shift lever cannot move further to contact the first contact 121 or the second contact 122. A distance B between an end surface of the abutting section 152 facing the inner bottom surface of the housing 110 and a tip end surface of the elastic section 151 may be set to be greater than a and 15mm or less. With such an arrangement, it can be avoided that the shift lever 140 is easily clamped into the arc-shaped structure of the elastic section 151 protruding toward the top end of the housing due to the over-large B, so that the shift lever 140 is locked, the cooking device 100 is always in a state of increasing or decreasing the working parameters, and even the body is damaged.

In order to make the shift lever 140 effectively contact with the abutting section 152 of the elastic limiting member 150, the resilience of the shift lever 140 is ensured, and the shift lever 140 can smoothly return to the original position. In some embodiments of the present invention, the distance C between the end surface of the end of the abutting section 152 facing the inner bottom surface of the casing 110 and the end surface of the end of the shifting lever 140 located in the casing 110 may be set to be greater than one fourth of a and less than B.

Fig. 9 is a schematic diagram of a rotation angle of the shift lever of the cooking apparatus according to an embodiment of the present invention, referring to fig. 9, in this embodiment, a maximum angle a of the shift lever 140 rotating on the housing 110 may be defined, and the angle a may be greater than 0 ° and less than 45 °. The maximum angle a is understood to mean the maximum angle of the sector formed by the left-most to the right-most dial 140.

It will be readily appreciated that a is within a suitable range such that the toggle lever 140 can be displaced without too much effort to achieve the function of adjusting the operating parameters. On the other hand, when the lever 140 is located at the original position, the lever 140 extending out of the housing 110 is not too long to affect the appearance of the cooking apparatus 100. In addition, the exposed part of the shift lever 140 can better fit with the shell 110 during operation, and the integrity of the appearance of the product is further improved.

Fig. 10 is the deformation angle schematic diagram of the butt section of the cooking utensil provided by the embodiment of the present invention, refer to fig. 10, and name the deformation angle of the butt section 152 as b, and b can be understood as that, when the shift lever 140 is shifted left or shifted right, the butt section 152 generates the directional direction and the vertical upward included angle of the deformed butt section 152. Therefore, the supporting section 153 of the elastic limiting member 150 is not broken, so that the elastic section 151 has elasticity for a long time, the service life of the elastic limiting member 150 is prolonged, and the shift lever 140 can be normally used.

Fig. 11 is a schematic structural diagram of the control board, the first contact, the second contact and the shift lever in fig. 1, and fig. 12 is a schematic structural diagram of the control board, the first contact, the second contact and the shift lever in fig. 2.

Referring to fig. 11, it is worth mentioning that, in order to enable the portion of the shift lever 140 contacting the first contact 121 or the second contact 122 to better contact the first contact 121 or the second contact 122, in some embodiments of the present invention, two sides of the portion of the shift lever 140 located between the first contact 121 and the second contact 122 may protrude toward a direction close to the first contact 121 and the second contact 122, respectively, so as to form a first trigger region 141 and a second trigger region 142. The first and second triggering regions 141 and 142 may prevent the lever 140 from making poor contact with the first or second contact 121 or 122, affecting the normal use of the cooking appliance 100, and may improve the accuracy of the adjustment of the operating parameters of the heater.

Wherein a side of one of the first trigger area 141 and the first contact 121 facing the other may be provided as a first slope 160. A second inclined surface 170 is provided on one of the second trigger region 142 and the second contact 122 facing the other.

Illustratively, as shown in fig. 9 and 11, a side of the first trigger region 141 facing the first contact 121 is provided as a first slope 160, and a side of the second trigger region 142 facing the second contact 122 is provided as a second slope 170. And an end of the first inclined surface 160 facing the first end of the lever 140 is inclined in a direction away from the first contact 121, and an end of the second inclined surface 170 facing the first end of the lever 140 is inclined in a direction away from the second contact 122.

Thus, when the shift lever 140 rotates to the first triggering area 141 to contact the first contact 121, or when the shift lever 140 rotates to the second triggering area 142 to contact the second contact 122, the first triggering area 141 or the second triggering area 142 is easily matched with the first contact 121 or the second contact 122, so that the end surface of the first contact 121 or the end surface of the second contact 122 is uniformly stressed when the end surface of the first contact 121 or the end surface of the second contact 122 is abutted by the first triggering area 141 or the second triggering area 142, and the stressed force is a forward force perpendicular to the end surface of the first contact 121 or the end surface of the second contact 122, thereby effectively prolonging the service life of the first contact 121 and the second contact 122.

In some embodiments of the present invention, the inclination angle of the first inclined plane 160 and the inclination angle of the second inclined plane 170 are both less than one-half of a.

Similarly, the side of the first contact 121 facing the first trigger area 141 may be set as a first slope, and the side of the second contact 122 facing the second trigger area 142 may be set as a second slope. And one end of the first inclined plane close to the opening 111 is inclined in a direction away from the first triggering area 141, and one end of the second inclined plane close to the opening 111 is inclined in a direction away from the second triggering area 142. The scheme is easy to understand, so that corresponding figures are not provided in the figures and are described in detail again.

Similarly, as shown in fig. 12, two sides of a portion of the shift lever 140 located between the first contact 121 and the second contact 122 may be recessed toward a direction away from the first contact 121 and the second contact 122, respectively. Of course, the end surface of the recessed region and the surface of the first contact 121 facing the other may be inclined, and the end surface of the recessed region and the surface of the second contact 122 facing the other may be inclined. The technical effects are the same as the first inclined surface 160 and the second inclined surface 170, and are not described in detail herein.

It should be mentioned that the distance between the first inclined surface 160 and the second inclined surface 170 needs to be smaller than the distance between the first contact 121 and the second contact 122, so as to ensure that the shift lever 140 can be assembled smoothly, and the distance difference between them can be greater than 0.3mm and less than or equal to 5mm, and the difference is preferably within 0.6 mm and 1.2mm, so as to ensure that the shift lever 140 cannot be easily contacted with the first contact 121 or the second contact 122 because of too large space, and cannot cause the phenomenon that the shift lever 140 is jammed with the first contact 121 or the second contact 122 or the condition that the shift lever 140 triggers a key by mistake because of too small space.

Still need mention, refer to fig. 8 and show, in some embodiments of the present invention, the position that is close to opening 111 in casing 110 can also set up water blocking rib 180, encloses between water blocking rib 180 and the partial inner wall of casing 110 and closes and form the recess, and the recess can prevent to flow into the inside components and parts that cause of organism from liquid such as water stain that opening 111 located the entering from the recess and damage.
