The induction cooker has multiple functions and multiple adjustable heating powers for users to select according to cooking types. In the prior art, two modes are generally adopted for adjusting the power of the induction cooker, one mode is to adjust the power by adding and subtracting keys, and the mode needs to be operated by pressing keys for many times and is inconvenient to operate. The other method is an adjustment method of a touch type or a combination of the touch type and a point touch, that is, power is adjusted by touch sliding or touch clicking, which is convenient to operate, but has a complex internal structure and special requirements on the material and electrical performance of the touch surface, resulting in high cost and limited structural design of the product. And above two kinds of modes, add and subtract key or touch key set up at the top surface mostly, in the use of electromagnetism stove, can appear greasy dirt or water stain and adhere to and lead to the malfunctioning condition of touch-control at the top surface, the user also very easily is touched the pan and is scalded by the hot water juice that spills or carelessness from the pot in addition, two kinds of conventional regulative modes above can lead to the product to lead to the general change seriously, and the breakthrough of constraint kitchen cooking utensil in structure and appearance changes.

In order to solve the problem, the embodiment of the utility model provides a cooking utensil rotates through the one end with the driving lever and connects in the casing, and outside the opening that the other end passed the casing side and seted up stretched out the casing, the mid portion of driving lever then passed between relative first button and the second button that sets up on being located the control panel, made driving lever and first button or the contact of second button through stirring the driving lever that is located outside the casing, adjusted the working parameter size of heater. Compare the mode that sets up plus-minus key or point formula of drawing touch at the casing top surface, can avoid casing top surface ponding or the phenomenon such as button failure or jump key that hot water caused, still can prevent when the casing top surface is operated, scalded by the pan or the hot water juice that spills to still can simplify assembly steps and operation etc.. Meanwhile, a first triggering section and a second triggering section are respectively arranged at the positions, opposite to the first key and the second key, of the shifting lever, and the first triggering section and the second triggering section are used for being in better contact with the first key and the second key so as to accurately adjust working parameters of the heater, so that the shifting lever is prevented from being in poor contact with the first key or the second key, and normal use of the cooking appliance is prevented from being influenced.

The invention is described below with reference to the accompanying drawings in conjunction with specific embodiments.

Fig. 1 is an effect diagram of a cooking appliance according to an embodiment of the present invention, and referring to fig. 1, a cooking appliance 100 has a housing 110, the housing 110 encloses a containing cavity, and components and parts for the cooking appliance 100 to operate are provided in the containing cavity.

Fig. 2 is a schematic perspective view of an internal structure of a cooking appliance provided in an embodiment of the present invention, as shown in fig. 1 and fig. 2, the components and parts thereof include a control board 120 and a heater 130, and the purpose of adjusting the operating parameters of the heater 130 by controlling the control board 120 is achieved, wherein the operating parameters may include: power, temperature, time, etc.

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 control board 120 controls the heater 130 to decrease or increase the operating parameter of the heater 130 according to a preset value. When the first button 121 or the second button 122 is continuously activated, the control board 120 controls the heater 130 to continuously decrease or increase the operating parameter of the heater 130.

It should be noted that the distance between the first key 121 and the second key 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.

With continued reference to fig. 1 and fig. 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, the second end of the shift lever 140 is rotatably disposed in the housing 110, and a portion of the shift lever 140 between the first end and the second end of the shift lever 140 passes through a space between the first button 121 and the second button 122, that is, the first button 121 and the second button 122 are respectively located on two sides of the shift 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.

Fig. 3 is a top view of an internal structure of a cooking appliance (a heating element is not shown) provided by an embodiment of the present invention, fig. 4 is an enlarged schematic view of a structure of a portion C in fig. 3, fig. 5 is a structural schematic view of a shift lever of the cooking appliance provided by an embodiment of the present invention, and fig. 6 is a structural schematic view of a control panel, a first button and a second button of the cooking appliance provided by an embodiment of the present invention.

Referring to fig. 2 to 6, a first triggering section 141 is disposed at a position of the lever 140 opposite to the first button 121, and a second triggering section 142 is disposed at a position of the lever 140 opposite to the second button 122, wherein the first triggering section 141 and the second triggering section 142 are used for contacting with the first button 121 or the second button 122 during rotation of the lever 140 to adjust an operating parameter of the heater 130.

It can be understood that the first and second triggering sections 141 and 142 are disposed on the shift lever 140, so that the shift lever can better contact with the first key 121 or the second key 122, the shift lever 140 is prevented from contacting the first key 121 or the second key 122 poorly, the normal use of the cooking appliance 100 is prevented from being affected, and the accuracy of the adjustment of the operating parameters of the heater can be improved.

In this embodiment, a surface of one of the first triggering segment 141 and the first key 121 facing the other may be provided as the first slope 150. A second inclined surface 160 is provided on a side of one of the second triggering section 142 and the second button 122 facing the other.

Illustratively, as shown in fig. 4 and 5, a side of the first triggering segment 141 facing the first key 121 is set as a first slope 150, and a side of the second triggering segment 142 facing the second key 122 is set as a second slope 160. And an end of the first inclined surface 150 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 surface 160 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 section 141 to contact the first button 121, or when the shift lever 140 rotates to the second triggering section 142 to contact the second button 122, the first triggering section 141 or the second triggering section 142 is easily engaged with the first button 121 or the second button 122, so that the end surface of the first button 121 or the end surface of the second button 122 is stressed uniformly when the first triggering section 141 or the second triggering section 142 is abutted against the end surface of the first button 121 or the end surface of the second button 122, and the stress is a positive stress perpendicular to the end surface of the first button 121 or the end surface of the second button 122, thereby effectively prolonging the service life of the first button 121 and the second button 122.

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

Referring to fig. 4 and 5, the second end of the shift lever 140 is rotatably disposed in the housing 110, the position-limiting post 112 of the shift lever 140 can be disposed in the accommodating cavity of the housing 110, the second end of the shift lever 140 is disposed with the rotating shaft 144, and the rotating shaft 144 is rotatably connected to the position-limiting post 112 to rotatably dispose the shift lever 140 in the housing.

For example, a rotation hole may be formed in one of the rotation shaft 144 and the position-limiting post 112, and then at least a portion of the other of the rotation shaft 144 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 on the position-limiting column 112, and the rotation shaft 144 of 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 on the rotation shaft 144 of 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. Further, an operating portion 143 may be provided at the first end of the lever 140, and one end of the operating portion 143 extends toward the distal end of the housing 110. The operation portion 143 can provide an easy-to-operate end for a user, so that usability of the cooking appliance is improved, and user experience is improved.

Fig. 7 is a schematic view of a cross-sectional structure along a cutting line D in fig. 3, fig. 8 is an enlarged schematic view of a structure of a portion E in fig. 7, fig. 9 is a schematic view of a rotation angle of a shift lever of a cooking appliance provided in an embodiment of the present invention, and fig. 10 is a plan view of an assembly of a control board, a first button, a second button and a shift lever provided in an embodiment of the present invention.

Referring to fig. 9, in the present embodiment, a maximum angle a of rotation of the lever 140 on the housing 110 may be defined, which 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.

Referring to fig. 10, in some embodiments of the present invention, the first inclined plane 150 has an inclination angle b1, the second inclined plane 160 has an inclination angle b2, and b1 is equal to b2, and b1 and b2 are all less than one-half of a.

Note that b1 indicates an angle between the extending direction of the first inclined surface 150 and the vertical direction when the lever 140 is viewed from above the cooking utensil 100. b2 indicates the angle between the extending direction of the second inclined plane 160 and the vertical direction when the shifting lever 140 is viewed from above the cooking utensil 100.

Therefore, the first trigger section 141 or the second trigger section 142 can be just matched with the first key 121 or the second key 122, so that the first key 121 surface or the second key 122 surface is stressed uniformly when being abutted by the first trigger section 141 or the second trigger section 142, and the stressed force is a positive force vertical to the end surface of the first key 121 or the end surface of the second key 122, and the service life of the first key and the second key can be effectively prolonged.

Referring to fig. 7 and 8, in order to provide the shift lever 140 with a sufficient assembly space, in some embodiments of the present invention, the interval a between the key surface of the first key 121 and the key surface of the second key 122 may be greater than or equal to 2mm and less than or equal to 20 mm. The A is best within 5mm-15mm, so that the deflector rod 140 can not be easily contacted with the first key 121 or the second key 122 because of overlarge space, and the phenomenon that the deflector rod 140 is dead against the first key 121 or the second key 122 or the condition that the deflector rod 140 triggers the keys by mistake because of the undersize space can not happen.

It is easy to understand that the shifter lever 140 needs to keep a proper distance from the first key 121 or the second key 122 to enable the best working effect of the shifter lever 140, so in some embodiments of the present invention, the maximum width B between the surface of the first triggering section 141 facing the first key 121 and the surface of the second triggering section 142 facing the second key 122 is less than a, and the difference between a and B is greater than or equal to 0.3mm and less than or equal to 5 mm. The difference between the two is optimal within 0.6mm-1.2mm, which can ensure that the shift lever 140 is not easy to contact with the first key 121 or the second key 122 because of too large space, and the shift lever 140 is not deadly against the first key 121 or the second key 122 or the shift lever 140 triggers the keys by mistake because of too small space.

Fig. 11 is a schematic diagram illustrating a left side of the shifting lever of the cooking apparatus provided by the embodiment of the present invention, and fig. 12 is a schematic diagram illustrating a right side of the shifting lever of the cooking apparatus provided by the embodiment of the present invention.

Referring to fig. 11 and 12, in the present embodiment, when the toggle lever 140 is shifted to the left, the first triggering segment 141 can be completely engaged with the first button 121. When the dial rod 140 is shifted to the right, the second triggering segment 142 can be fully engaged with the second button 122. The first key 121 and the second key 122 are prevented from being worn by the first trigger section 141 and the second trigger section 142 when the first trigger section and the second trigger section are used for a long time, and the service lives of the first key and the second key can be effectively prolonged.

Fig. 13 is a schematic structural diagram of a housing of a cooking appliance according to an embodiment of the present invention, and fig. 14 is an enlarged schematic structural diagram of a portion G in fig. 13;

referring to fig. 4 and 11 to 14, 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 in a reverse direction 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.
