The control panel 120 can be fixed on the inner bottom surface of the housing 110 in a limited manner by means of support ribs, buckles, screws, or the like.

In this embodiment, the control board 120 has two opposite first keys 121 and second keys 122, and the first key 121 or the second key 122 is activated to adjust the elevation of the operating parameter of the heater 130, for example, the first key 121 is activated to lower the operating parameter of the heater, and the second key 122 is activated to raise the operating parameter of the heater, or the first key 121 is activated to raise the operating parameter of the heater, and the second key 122 is activated to lower the operating parameter of the heater. It should be noted that the touch is divided into a point touch and a continuous touch, and when the first key 121 or the second key 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. When first key 121 or second key 122 is continuously activated, controller 120 controls heater 130 to continuously decrease or increase the operating parameter of heater 130.

With continued reference to fig. 1 and 2, the components and parts further include a shift lever 140, a first end of the shift lever 140 is located outside the housing 110, the first end of the shift lever 140 can be regarded as an operation end, a second end of the shift lever 140 extends into the housing through an opening 111 formed in a side surface of the housing 110, and the second end of the shift lever 140 is rotatably disposed in the housing 110, so that the first end of the shift lever 140 rotates around the second end and the shift lever 140 is used to contact with the first key 121 or the second key 122 during the rotation process to trigger the adjustment of the operating parameter. A portion of the lever 140 between the first end and the second end of the lever 140 passes through the first button 121 and the second button 122, i.e., the first button 121 and the second button 122 are respectively located at two sides of the lever 140. 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 key 121, or by rotating the toggle lever 140 to the right to contact the second key 122 to increase or decrease the operating parameter of the heater 130.

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.

Referring to fig. 5 and 6, in the present embodiment, the second end of the shift lever 140 has a rotating shaft 141, two ends of the rotating shaft 141 respectively face the top end and the bottom end of the housing 110, and the second end of the shift lever 140 is rotatably disposed in the housing 110 through the rotating shaft 141.

Referring to fig. 2, 5 and 6, in the present embodiment, a limiting member 112 is disposed in the housing 110 and is rotatably connected to the rotating shaft 141 and concentric with the rotating shaft 141, and the second end of the shift lever 140 is rotatably connected to the limiting member 112 through the rotating shaft 141 and is rotatably disposed in the housing 110.

One of the rotating shaft 141 and the limiting member 112 may be provided with a rotating hole, and then at least a portion of the other of the rotating shaft 141 and the limiting member 112 is disposed in the rotating hole, so that the shift lever 140 is rotatably disposed in the housing 110.

Referring to fig. 3 and 4, in some embodiments of the present invention, in order to facilitate assembly and observation of components and parts inside the cooking utensil 100, the phenomenon of wrong assembly of components and parts is avoided, the casing 110 may be divided into the bottom casing 114 and the upper cover 115, the limiting member 112 is divided into the first limiting post 1121 and the second limiting post 1122, the first limiting post 1121 is disposed on the inner bottom surface of the bottom casing 114, the second limiting post 1122 is disposed on the inner wall of the upper cover 115 through the connecting member, and the opening 111 may be disposed on the side wall of the bottom casing 114.

For example, as shown in fig. 3 to 5 and fig. 7 to 9, a first rotation hole 151 may be formed at a top end of the first limiting pillar 1121, a second rotation hole 152 may be formed at one end of the second limiting pillar 1122 facing the first limiting pillar 1121, and then two ends of the rotation shaft 141 are respectively disposed in the first rotation hole 151 and the second rotation hole 152 to realize that the shift lever 140 is rotatably disposed in the housing 110.

It is easy to understand that, since the first position-limiting post 1121 is fixedly connected to the bottom housing 114, and the second position-limiting post 1122 is fixedly connected to the upper cover 115, and after the two ends of the rotating shaft 141 are respectively inserted into the first rotating hole 151 and the second rotating hole 152, the second end of the shift lever 140 cannot be separated from the original position in the working process, so that the assembling stability of the shift lever 140 is improved, and the structure is simple and easy to implement. In addition, a limiting piece and a screw for limiting the deflector rod 140 can be omitted, the assembly steps are reduced, the material and labor cost is reduced, and the production efficiency of the product is improved.

In order to ensure that the rotating shaft 141 can be inserted into the first rotating hole 151 and the second rotating hole 152, and the insertion of the rotating shaft 141 is not blocked due to the small size of the first rotating hole 151 or the second rotating hole 152, or the abnormal sound of the shift lever 140 during operation due to the large size of the first rotating hole 151 or the second rotating hole 152, in some embodiments of the present invention, the inner diameter Φ 1 of the first rotating hole 151 and the inner diameter Φ 2 of the second rotating hole 152 may be set to be greater than the outer diameter Φ 3 of the rotating shaft 141, and the difference between the inner diameter Φ 1 of the first rotating hole 151 and the inner diameter Φ 2 of the second rotating hole 152 and the outer diameter Φ 3 of the rotating shaft 141 is greater than or equal to 0.3mm and less than or equal to 3mm, respectively.

For another example, referring to fig. 3, 4 and 6, for example, third rotation holes 153 may be respectively disposed at two ends of the rotating shaft 141, and then the top end of the first position-limiting column 1121 and the bottom end of the second position-limiting column 1122 are respectively inserted into the third rotation holes 153 at two ends of the rotating shaft 141, so as to realize that the shift lever is rotatably disposed in the housing 110.

It is easy to understand that, since the first position-limiting post 1121 is fixedly connected to the bottom housing 114, and the second position-limiting post 1122 is fixedly connected to the upper cover 115, after the top end of the first position-limiting post 1121 and the bottom end of the second position-limiting post 1122 are respectively inserted into the third rotation holes 153 at the two ends of the rotation shaft 141, the second end of the shift lever 140 cannot be separated from the original position in the working process, the assembly stability of the shift lever 140 is improved, and the structure is simple and easy to implement. In addition, a limiting piece and a screw for limiting the deflector rod 140 can be omitted, the assembly steps are reduced, the material and labor cost is reduced, and the production efficiency of the product is improved.

In order to guarantee that first spacing post 1121 and second spacing post 1122 can peg graft smoothly in third rotation hole 153 to can not be obstructed when leading to first spacing post 1121 and the spacing post 1122 of second to peg graft because third rotation hole 153 undersize, perhaps, can not make driving lever 140 take place the abnormal sound because third rotation hole 153 is too big at the during operation, in some embodiments of the utility model, can set the internal diameter of third rotation hole 153 to be greater than the external diameter of first spacing post 1121 and second spacing post 1122, and the difference more than or equal to 0.3mm and less than or equal to 3mm between the internal diameter of third rotation hole 153 and the external diameter of first spacing post 1121 and the spacing post 1122 of second.

Referring to fig. 7 to 9, in some embodiments of the present invention, a distance H1 from the top end of the first position-limiting pillar 1121 to the bottom end of the second position-limiting pillar 1122 may be set to be smaller than a height H2 of the rotating shaft 141, and a difference between H1 and H2 is greater than 3 mm.

It can be understood that the H1 is smaller than the H2, so that the shifting lever 140 cannot fall off in the working process, and the difference between the H1 and the H2 is larger than 3mm, so that the shifting lever 140 cannot be stuck due to the small difference between the H1 and the H2 in the working process.

In order to avoid the interference between the non-rotation shaft portion of the shift lever 140 and the first and second position-limiting pillars 1121 and 1122, the non-rotation shaft portion of the shift lever 140 is clamped between the first and second position-limiting pillars 1121 and 1122, so that the shift lever 140 is locked, in some embodiments of the present invention, the thickness H of the portion of the shift lever 140 between the first and second keys 121 and 122 can be set to be smaller than H1, and the difference between H and H1 is greater than 0.3 mm.

Referring to fig. 12-14, 16 and 17, in some embodiments of the present invention, a support rib 160 may be further disposed in the housing 110 near the opening 111, the support rib 160 may be used to support the shift lever 140, and the top surface of the support rib 160 is higher than the bottom edge of the opening 111.

Therefore, the driving lever 140 can be prevented from being in direct contact with the bottom edge of the opening 111, and particularly, under the condition that four corners of the opening 111 are rounded, the driving lever 140 can be ensured not to have a bumpy feeling in the left-moving or right-moving process, and the user experience is further improved.

It is worth mentioning that some embodiments of the present invention can set the distance B1 from the top surface of the support rib 160 to the bottom surface of the bottom shell 114 to be greater than the height B of the first position-limiting post 1121, so as to ensure that the whole driving lever 140 can be horizontally placed, thereby avoiding the phenomenon of locking of the driving lever 140 due to the non-horizontal state of the driving lever 140.

As shown in fig. 15, the opening 111 may be rectangular, and four corners of the rectangle may be rounded, which may facilitate the demolding of the housing 110.

As shown in fig. 16 and 17, a groove 113 may be formed between the support rib 160 and a portion of the inner wall of the housing 110, and the groove 113 may prevent liquid such as water stain entering from the opening 111 from flowing into the interior of the housing to damage components.

Referring to fig. 10 to 14, it should be noted that in the present embodiment, the height B of the first position-limiting pillar 1121 may be set to be smaller than the height B2 of the bottom case 114, and the height a of the second position-limiting pillar 1122 may be set to be smaller than the height a1 of the upper cover 115, so that when the bottom case 114 and the upper cover 115 are assembled, a gap between the bottom case 114 and the upper cover 115 may not be generated because the heights of the first position-limiting pillar 1121 and the second position-limiting pillar 1122 are greater than the heights of the bottom case 114 and the upper cover 115.

Fig. 18 is another view structure diagram of fig. 17, referring to fig. 17 and 18, in some embodiments of the present invention, at least two elastic stoppers 170 may be further disposed in the housing 110, the at least two elastic stoppers 170 are also respectively located at two sides of the shift lever 140, and the elastic stoppers 170 are used to drive the shift lever 140 to rotate reversely after the shift lever 140 rotates to be in contact with one of the pressing keys, so as to reset the shift lever 140.

The middle portion of the shift lever 140 passes through the two elastic stoppers 170, and the elastic stoppers 170 allow the shift lever 140 to contact the first key 121 or the second key 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 key 121 or the second key 122, so that the adjustment of the operating parameter is inaccurate, 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.

The elastic limiting member 170 may be of an inverted "J" shape, the elastic limiting member 170 may include a supporting portion 171, an elastic portion 172 and an abutting portion 173, two ends of the supporting portion 171 are respectively connected to the inner bottom surface of the casing 110 and one end of the elastic portion 172, the other end of the elastic portion 172 is connected to one end of the abutting portion 173, the other end of the abutting portion 173 faces the inner bottom surface of the casing 110 and is disposed in a suspended manner, and the elastic portion 172 is of an arc structure protruding toward the top end of the casing 110.

The supporting portion 171 can be used to support the elastic portion 172 and the abutting portion 173, and connect the elastic portion 172 and the abutting portion 173 with the housing 110, so as to improve the structural stability of the elastic limiting member 170. The abutting portion 173 is used for contacting the shift lever 140, so as to prevent the shift lever 140 from directly contacting the elastic portion 172, causing abrasion to the elastic portion 172 and affecting resilience performance. The elastic member is used to give an elastic force to the abutting portion 173, and is transmitted to the shift lever 140 through the abutting portion 173, so that when the shift lever 140 contacts the key, the shift lever 140 is driven to rotate reversely and return to the original position. In order to prevent the shift lever 140 from directly contacting the elastic portion 172 of the elastic limiting member 170, it is effectively ensured that the shift lever 140 does not abut against the elastic portion 172 during operation, so that the shift lever cannot move further to contact the first button 121 or the second button 122. The distance between the end surface of the abutting portion 173 facing the inner bottom surface of the housing 110 and the end surface of the elastic portion 172 may be set to be greater than the thickness of the end of the lever 140 located in the housing 110 and equal to or less than 15 mm. With such an arrangement, it can be avoided that the shifting lever 140 is easily clamped into the arc-shaped structure of the elastic portion 172 protruding toward the top end of the housing due to the excessively large distance between the end surface of the abutting portion 173 facing the inner bottom surface of the housing 110 and the end surface of the top end of the elastic portion 172, so that the shifting lever 140 is locked, and the cooking appliance 100 is always in a state of increasing or decreasing the operating parameters, or even the body is damaged.

In order to make the shift lever 140 effectively contact with the abutting portion 173 of the elastic stopper 170, 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 between the end surface of the end of the abutting portion 173 facing the inner bottom surface of the housing 110 and the end surface of the end of the shifting rod 140 located in the housing 110 may be set to be greater than one fourth of the thickness of the end of the shifting rod 140 located in the housing 110 and smaller than the distance between the end surface of the end of the abutting portion 173 facing the inner bottom surface of the housing 110 and the end surface of the elastic portion 172.

The elastic portion 172, the abutting portion 173 and the supporting portion 171 cooperate to ensure resilience to the shift lever 140, and to prolong the service life of the elastic stopper 170.

It should be noted that, referring to fig. 5 and 6, in order to make the portion of the shift lever 140 contacting the first key 121 or the second key 122 better contact the first key 121 or the second key 122, in some embodiments of the present invention, two sides of the portion of the shift lever 140 located between the first key 121 and the second key 122 may protrude toward the direction close to the first key 121 and the second key 122 respectively to form the first triggering area 142 and the second triggering area 143. The first and second triggering regions 142 and 143 prevent the lever 140 from making poor contact with the first or second buttons 121 and 122, affecting the normal use of the cooking appliance 100, and improve the accuracy of the adjustment of the operating parameters of the heater.

Here, a side of one of the first triggering area 142 and the first key 121 facing the other may be provided as a first slope 180. A second inclined plane 190 is provided to a side of one of the second triggering area 143 and the second key 122 facing the other.

Illustratively, as shown in fig. 5 and 6, a side of the first triggering area 142 facing the first key 121 is set as a first inclined plane 180, and a side of the second triggering area 143 facing the second key 122 is set as a second inclined plane 190. And an end of the first inclined plane 180 facing the first end of the shifter lever 140 is inclined in a direction away from the first button 121, and an end of the second inclined plane 190 facing the first end of the shifter lever 140 is inclined in a direction away from the second button 122.

Thus, when the shift lever 140 rotates to the first triggering area 142 to contact the first key 121, or when the shift lever 140 rotates to the second triggering area 143 to contact the second key 122, the first triggering area 142 or the second triggering area 143 is easily engaged with the first key 121 or the second key 122, so that the end surface of the first key 121 or the end surface of the second key 122 is uniformly stressed when the end surface of the first key 121 or the end surface of the second key 122 is abutted by the first triggering area 142 or the second triggering area 143, and the stressed force is a forward force perpendicular to the end surface of the first key 121 or the end surface of the second key 122, thereby effectively prolonging the service life of the first key 121 and the second key 122.

In some embodiments of the present invention, the inclination angle of the first inclined plane 180 and the inclination angle of the second inclined plane 190 are both smaller than one-half of a.

Similarly, the side of the first key 121 facing the first trigger area 142 may be set as a first inclined surface, and the side of the second key 122 facing the second trigger area 143 may be set as a second inclined surface. And one end of the first inclined surface close to the opening 111 is inclined in a direction away from the first triggering area 142, and one end of the second inclined surface close to the opening 111 is inclined in a direction away from the second triggering area 143.
