The assembly step of fixing the adjusting rod 120 and the limiting member 150 by using the structural member can be omitted, which is beneficial to simplifying the structure, reducing the parts, improving the production efficiency, reducing the product cost and the like.

It should be understood that, if a rotation hole is formed on the rotation shaft 121, at this time, the first through hole is located in the rotation hole, the second reverse buckle is shaped like the first reverse buckle in fig. 5, and protrudes radially outward, when the second reverse buckle passes through the first through hole, the second reverse buckle can radially contract, so that the second reverse buckle smoothly passes through the first through hole, and after the second reverse buckle passes through the first through hole, the second reverse buckle expands and returns to the original position, and is clamped with the first reverse buckle, thereby completing the assembly between the adjustment rod 120 and the limiting member 150.

For example, fig. 11 is a schematic structural diagram of the adjusting lever 120 of the cooking appliance 100 according to an embodiment of the present invention, referring to fig. 8 and 11, when the bottom casing 112 has the first position-limiting post 153, and a portion of the first position-limiting post 153 and the second inverse buckle 152 have the second break 160, the structure of the adjusting lever 120 may be as shown in fig. 11, one end of the rotating shaft 121 of the adjusting lever 120 facing the first position-limiting post 153 is provided with a first inverse buckle 1211, when the first inverse buckle 1211 passes through the second through hole 1521, the second inverse buckle 152 may be radially expanded, so that the first inverse buckle 1211 smoothly passes through the second through hole 1521, and after the first inverse buckle 1211 passes through the second through hole 1521, the second inverse buckle 152 is retracted to return to the original position, and is clamped with the first inverse buckle 1211, so as to complete the assembly between the adjusting lever 120 and the position-limiting member 150.

The number of the second interruptions 160 is preferably between 2 and 8, so that the first inverted buckle 1211 can pass through the second through hole 1521, and the assembly stability between the adjustment rod 120 and the limiting member 150 is prevented from being affected by the excessive number of the second interruptions 160.

Referring to fig. 12 to 21, in some embodiments of the present invention, except that the structures of the adjustment rod 120 and the position limiter 150 are different, the other structures are the same as the cooking appliance 100 described above, and are not repeated herein.

Specifically, referring to fig. 18, 19 and 21, the limiting member 150 and the second inverse buckle 152 may not have the second break 160, at this time, the adjusting rod 120 may be shaped as shown in fig. 21, one end of the rotating shaft 121 of the adjusting rod 120 facing the first limiting post 153 is provided with a first inverse buckle 1211, the first inverse buckle 1211 and at least a part of the rotating shaft 121 are provided with at least two first breaks 170, when the first inverse buckle 1211 passes through the second through hole 1521 on the first limiting post 153, the first inverse buckle 1211 may radially contract, so that the first inverse buckle 1211 can smoothly pass through the second through hole 1521, and after the first inverse buckle 1211 passes through the second through hole 1521, the first inverse buckle 1211 expands to return to the original position, and is clamped with the second inverse buckle 152, thereby completing the assembly between the adjusting rod 120 and the limiting member 150. The assembly step of fixing the adjusting rod 120 and the limiting member 150 by using the structural member can be omitted, which is beneficial to simplifying the structure, reducing the parts, improving the production efficiency, reducing the product cost and the like.

It should be understood that, if a rotation hole is formed on the rotation shaft 121, at this time, the first through hole is located in the rotation hole, the second reverse buckle is shaped like the first reverse buckle in fig. 21, and protrudes radially outward, when the second reverse buckle passes through the first through hole, the first through hole can be radially expanded, so that the second reverse buckle smoothly passes through the first through hole, and after the second reverse buckle passes through the first through hole, the first through hole shrinks and returns to the original position, so that the first reverse buckle and the second reverse buckle realize the clamping, and the assembly between the adjustment rod 120 and the limiting member 150 is completed.

The number of the first breaks 170 is preferably between 2 and 8, so that the first inverse buckle 1211 can pass through the second through hole 1521, and the assembly stability between the adjustment rod 120 and the limiting member 150 is prevented from being affected by the excessive number of the first breaks 170.

Referring to fig. 5 and 15, in some embodiments of the utility model, when the limiting member 150 is provided with the rotating hole 151, the first inverse buckle 1211 is in interference fit with the second through hole 1521, so that the first inverse buckle 1211 is clamped with the second inverse buckle 152, and the interference fit distance W1 is between 0.1mm and 2mm, on one hand, the stability of clamping the first inverse buckle 1211 and the second inverse buckle 152 can be ensured, and the regulating rod 120 is not clamped with the limiting member 150. On the other hand, it is avoided that the interference fit distance is too large, and the friction force between the first inverse buckle 1211 and the second inverse buckle 152 is too high, so as to affect the rotation of the rotating shaft 121.

It should be understood that, when the rotating shaft 121 is provided with the rotating hole, the second reverse buckle is in interference fit with the first through hole, so that the second reverse buckle is clamped with the first reverse buckle, and the interference fit distance is 0.1mm-2 mm.

With continued reference to fig. 5 and 15, in some embodiments of the utility model, when the limiting member 150 has the rotation hole 151, the outer diameter W2 of the first inverse buckle 1211 is smaller than the inner diameter W3 of the rotation hole 151, so as to ensure that the first inverse buckle 1211 does not interfere with the inner wall of the rotation hole 151, and the adjustment rod 120 is locked.

It should be understood that when the rotation hole is formed on the rotation shaft 121, the outer diameter of the second reverse buckle is smaller than the inner diameter of the rotation hole.

Referring to fig. 5 and 15, in some embodiments of the utility model, when the limiting member 150 is provided with the rotation hole 151, the distance between the diameter W4 of the second through hole 1521 and the outer diameter W5 of the rotation shaft 121 is between 0.1mm and 1 mm. The adjusting lever 120 is not jammed and the adjusting lever 120 is not shaken.

It should be understood that when the rotating shaft 121 is provided with a rotating hole, the diameter of the first through hole is 0.1mm to 1mm larger than the outer diameter of the limiting member 150.

Referring to fig. 2 and 8, in some embodiments of the present invention, at least two elastic restoring members 180 may be further disposed in the housing 110, the at least two elastic restoring members 180 are also disposed at both sides of the adjusting lever 120, respectively, and the elastic restoring members 180 are used to drive the adjusting lever 120 to rotate in a reverse direction after the adjusting lever 120 rotates to contact one of the keys, so as to restore the adjusting lever 120.

The middle portion of the adjustment lever 120 passes through between the two elastic reset members 180, and the elastic reset members 180 allow the adjustment lever 120 to contact the first touch key 131 or the second touch key 132 and to be driven to rotate in the opposite direction after the external force is removed, so that the adjustment lever 120 is reset. The adjustment lever 120 is prevented from being excessively adjusted up or down due to the long-time contact with the first touch key 131 or the second touch key 132, so that the adjustment of the operating parameters is inaccurate, and even the cooking appliance 100 is always in a state of increasing or decreasing the operating parameters, so that the machine body is damaged.

Fig. 22 is a schematic view illustrating a rotation angle of the adjustment lever 120 of the cooking appliance 100 according to an embodiment of the present invention, and referring to fig. 22, in the embodiment, a maximum angle a of the adjustment lever 120 rotating on the housing 110 may be defined, and 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 lever 120 being moved from the left to the right.

It is easy to understand that a is in a proper range, on one hand, the displacement of the toggle adjusting lever 120 can be adjusted without too large to achieve the function of adjusting the working parameters. On the other hand, when the adjustment lever 120 is located at the original position, the adjustment lever 120 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 adjusting rod 120 can be better attached to the shell 110 when running, and the integrity of the appearance of the product is further improved.

Fig. 23 is a schematic structural view illustrating the matching of the adjusting lever 120 and the control board 130 of the cooking appliance 100 according to an embodiment of the present invention, and referring to fig. 23, it should be noted that, in order to enable a portion of the adjusting lever 120 contacting the first touch key 131 or the second touch key 132 to better contact the first touch key 131 or the second touch key 132, in some embodiments of the present invention, two sides of a portion of the adjusting lever 120 located between the first touch key 131 and the second touch key 132 may be respectively protruded toward a direction close to the first touch key 131 and the second touch key 132 to form the first touch section 122 and the second touch section 123. The first contact section 122 and the second contact section 123 are used for contacting with the first contact key 131 or the second contact key 132 during the rotation of the adjusting rod 120 to adjust the working parameter of the heater 140. The first and second contact sections 122 and 123 may prevent the adjustment lever 120 from being in poor contact with the first or second touch key 131 or 132, which may affect the normal use of the cooking appliance 100, and may improve the accuracy of the adjustment of the operating parameters of the heater 140.

Fig. 24 is a top view of the adjusting lever 120 of the cooking appliance 100 cooperating with the control plate 130 according to an embodiment of the present invention, as shown in fig. 24, wherein a surface of one of the first contact section 122 and the first contact key 131 facing the other may be set as a first inclined surface 1221. A surface of one of the second contact section 123 and the second key 132 facing the other is provided as a second inclined surface 1231.

Illustratively, as shown in fig. 24, a side of the first contact segment 122 facing the first key touch 131 is set as a first inclined surface 1221, and a side of the second contact segment 123 facing the second key touch 132 is set as a second inclined surface 1231. The first inclined surface 1221 is inclined at an angle b1 toward the first end of the adjustment lever 120, and the second inclined surface 1231 is inclined at an angle b2 toward the first end of the adjustment lever 120.

Therefore, when the adjusting rod 120 rotates to the position where the first contact section 122 contacts the first touch key 131, or when the adjusting rod 120 rotates to the position where the second contact section 123 contacts the second touch key 132, the first contact section 122 or the second contact section 123 is easily matched with the first touch key 131 or the second touch key 132, so that the end surface of the first touch key 131 or the end surface of the second touch key 132 is uniformly stressed when the end surface of the first touch key 131 or the end surface of the second touch key 132 is abutted by the first contact section 122 or the second contact section 123, and the stressed force is a forward force perpendicular to the end surface of the first touch key 131 or the end surface of the second touch key 132, thereby effectively prolonging the service life of the first touch key 131 and the second touch key 132.

In some embodiments of the present invention, the inclination angle b1 of the first inclined surface 1221 and the inclination angle b2 of the second inclined surface 1231 are equal and are both smaller than one-half of a.

Similarly, a side of the first touch key 131 facing the first touch segment 122 may be set as a first inclined surface, and a side of the second touch key 132 facing the second touch segment 123 may be set as a second inclined surface. And the end of the first inclined plane close to the opening 111 is inclined in the direction away from the first contact section 122, and the end of the second inclined plane 1231 close to the opening 111 is inclined in the direction away from the second contact section 123.
