Illustratively, the included angle between the wire portion and the fixed portion is in the range of 110 degrees to 150 degrees. When the included angle between the connection part and the fixing part is smaller than 110 degrees, the space occupied by the connection part and the wires (or the wires and the pluggable connecting piece) connected with the connection part may be excessively large, and in fact, the space in the pot body is very limited. When the included angle between the wire connection part and the fixing part is greater than 150 degrees, it may be inconvenient for the wire (or the wire and the pluggable connection member) to be connected with the wire connection part. Of course, the scope of this application does not exclude angles less than 110 and angles greater than 150.

Or alternatively, the transfer terminals are provided on a plurality of the heat shield, the heating assembly and the housing. The heating assembly is usually high in temperature, and the switching terminal is directly arranged on the heating assembly and can be influenced by high temperature to shorten the service life. The structural difference of the housings may be large for different models, so that it may be difficult to process the adapter terminal into a standard to fit all the housings if the adapter terminal is provided on the housing, and the space on the housing must be limited. Therefore, it is preferable to provide the heat insulating cover with the adapter terminal. The structure of the heat preservation cover is simpler, and the structure of the heat preservation cover is not changed greatly under different machine types, so that the installation of the switching terminal is facilitated.

Illustratively, the adapter terminal is disposed at the outside bottom of the heat retaining cover. Therefore, the switching terminal is arranged on the outer side of the heat preservation cover, the space between the heat preservation cover and the shell can be fully utilized, the space on the inner side of the heat preservation cover is not occupied, the design of the inner pot with larger volume is facilitated, and the capacity of the cooking utensil is improved.

The outer case 600 is the outermost part of the pot body 10, and may surround the inner pot 400, the heating assembly 500, the heat-retaining cover 100, and the like. To increase the useful life of the cooking appliance, in some alternative embodiments, the housing 600 may be made of a metallic material.

The housing 600 (when made of a metal material), the heat-retaining cover 100, the temperature measuring assembly 700, the heating assembly 500, etc. may be components to be grounded in the pot body 10. In addition, if necessary, the cover body can also comprise a part to be grounded, such as a temperature measuring component on the cover body, a metal shell of the cover body, and the like. When the part to be grounded is grounded, the electric charge on the part to be grounded can be conducted to the ground through the ground wire, so that the electric shock risk is avoided. As shown in fig. 1 to 5, the pot 10 may further include an adapter terminal 200. The switch terminal 200 may be provided on any one or more of the aforementioned components to be grounded. The adapter terminal 200 may be made of metal. One of the transit terminal 200 and the member to be grounded may be provided with a stopper 300. The member to be grounded is a member to be grounded provided with the transit terminal 200. In the illustrated embodiment, the component to be grounded is a thermal shield 100. The other one of the transit terminal 200 and the member to be grounded may be provided with a limiting hole 110. The stopper 300 may be inserted into the stopper hole 110. It can be appreciated that, when the limiting portion 300 is disposed on the adapter terminal 200, the limiting hole 110 may be disposed on the member to be grounded. In another embodiment, not shown, the transit terminal 200 may be provided with a limiting hole 110, and the member to be grounded may be provided with a limiting part 300. In any embodiment, the limiting portion 300 and the adaptor terminal 200 or the member to be grounded may be integrally formed, or may be separately formed and then connected together, which is not limited herein. The limiting hole 110 may be a round hole, a square hole, or a kidney-shaped hole, as long as the limiting function of the limiting part 300 inserted therein is satisfied.

The transit terminal 200 may be connected to the component to be grounded by a fastener (not shown). The mounting process of the switching terminal 200 and the component to be grounded of the cooking appliance is as follows: firstly, the limiting part 300 is directly inserted into the limiting hole 110, so that the pre-installation of the switching terminal 200 and the component to be grounded can be realized, and the switching terminal 200 is ensured to be positioned at a desired position on the component to be grounded. In the case where the adapter terminal 200 and the member to be grounded are both provided with fastening holes, the fastening holes can be ensured to be aligned with each other. Then, the transit terminal 200 may be connected to the member to be grounded by a fastener.

For example, the fastener may comprise a threaded fastener or a rivet. The threaded fasteners may include one or more of screws, bolts, nuts, and the like. As shown in fig. 3 to 4 and 7, the transit terminal 200 may be provided with a first fastening hole 201. As shown in fig. 5 to 6, the member to be grounded may be provided with a second fastening hole 101. When the fastener is a screw, the first fastening hole 201 may be previously provided on the transit terminal 200 and the second fastening hole 101 may be previously provided on the member to be grounded, so that the screw may pass through both fastening holes to connect the transit terminal 200 to the member to be grounded. When the fastener is a rivet, the self-piercing riveting manner can be directly adopted, at this time, the first fastening hole 201 does not need to be provided on the transit terminal 200 in advance, the second fastening hole 101 does not need to be provided on the component to be grounded in advance, the rivet is directly self-pierced through the transit terminal 200 and the component to be grounded through the self-piercing riveting tool, and then the transit terminal 200 is connected to the component to be grounded. It will be appreciated that when the fastener is a rivet, the first fastening hole 201 may be provided in advance on the transit terminal 200, the second fastening hole 101 may be provided in advance on the member to be grounded, then the rivet may be passed through both fastening holes, and then pressure may be applied to the rivet by a simple tool, thereby connecting the transit terminal 200 to the member to be grounded. The fastener can make the transfer terminal 200 closely fit with the component to be grounded, ensuring that the transfer terminal 200 can be in electrical contact with both components to be grounded.

According to the connecting terminal 200, the limiting hole 110 is formed in one of the connecting terminal 200 and the part to be grounded, the limiting part 300 is arranged on the other one of the connecting terminal 200 and the part to be grounded, when the connecting terminal 200 and the part to be grounded are assembled, the connecting terminal 200 can be easily installed in place on the part to be grounded only by plugging the limiting part 300 into the limiting hole 110, and then the connecting terminal 200 is connected to the part to be grounded through the fastener. Thus, the connection process is simple and convenient, and the connection is reliable; the connection and installation process is greatly simplified, and the working procedures are simplified. In addition, the process stability of the process limiting hole 110 is higher than that of the prior art, and the accuracy of the position and the size thereof can be ensured, thereby providing a premise for aligning the adapter terminal 200 and the fastening hole (if any) on the component to be grounded. In addition, the limiting hole 110 has low requirements on the setting position and is easier to process, and can be arranged at any proper position according to the requirement, so that the processing difficulty of the limiting hole 110 of the cooking utensil can be greatly reduced, and the production cost is further reduced. Furthermore, the insertion of the limiting portion into the limiting hole may also prevent the adaptor terminal 200 and the member to be grounded from rotating or shifting with respect to each other during and after the installation.

As illustrated in fig. 1 to 6, the component to be grounded to which the transit terminal 200 is mounted may be a heat insulation cover 100, for example. So set up, after the switching terminal 200 is connected to the heat preservation cover 100 through the fastener, the two can realize electric contact, and the switching terminal 200 is connected to the heat preservation cover 100 by means of the wire. If necessary, other components to be grounded may be electrically connected to the transit terminal 200 by wires, whereby grounding of all the components to be grounded may be achieved. Of course, alternatively, the adapter terminal 200 may be mounted on the heating assembly 500 or on the housing 600. Or alternatively, the adapter terminal 200 is provided on a plurality of the heat insulation cover 100, the heating assembly 500, and the case 600. The heating element 500 is usually at a higher temperature, and the direct placement of the adapter terminal 200 on the heating element 500 may be affected by the high temperature, which may shorten the service life. The structural difference of the case 600 may be large for different models, so if the adapter terminal is provided on the case 600, it may be difficult to process the adapter terminal into a standard to fit all the cases 600, and the space on the case 600 must be limited. Therefore, the adapter terminal 200 is preferably provided on the heat insulation cover 100. The structure of the heat preservation cover 100 is simple, and the structure of the heat preservation cover 100 is not changed greatly under different models, so that the installation of the switching terminal 200 is facilitated.

For example, as shown in fig. 1 to 3, the transit terminal 200 may be provided at the outer bottom of the heat insulation cover 100. The inner side of the heat preservation cover 100 accommodates an inner pot 400. There is typically a large space between the insulating cover 100 and the housing 600. In this way, the adaptor terminal 200 is arranged on the outer side of the heat insulation cover 100, so that the space between the heat insulation cover 100 and the casing 600 can be fully utilized, the space on the inner side of the heat insulation cover 100 is not occupied, the inner pot 400 with larger volume is convenient to design, and the capacity of the cooking utensil is improved. Moreover, since the inner pot 400 needs to be frequently taken out and put in, the transit terminal 200 is disposed at the outer side of the heat insulation cover 100, and the transit terminal 200 is not touched or bumped when the inner pot 400 is placed, thereby prolonging the service life of the transit terminal 200. In addition, the adaptor terminal 200 can be directly inverted with respect to the pot body 10 at the bottom of the outside of the heat insulation cover 100 when the adaptor terminal 200 is replaced and installed, and the opening of the pot body 10 is positioned at the lowermost end, so that the opening of the pot body 10 is generally flat, and is convenient for stable support, thereby facilitating the operation of operators.

Illustratively, the spacing portion 300 may be plural and spaced around the fastener. The spacing between any adjacent two of the plurality of limiting portions 300 may be equal or unequal. The limiting holes 110 may be plural and correspond to the plural limiting parts 300 one by one. So set up, a plurality of spacing portions 300 peg graft with a plurality of spacing holes 110 one-to-one for the switching terminal 200 and wait to ground the part can be spacing in a plurality of positions, thereby guarantee that switching terminal 200 can be located the predetermined position department on waiting to ground the part accurately. If the limit is performed only at a single position, when the caulking is performed, the transfer terminal and the member to be grounded may be loose and offset, and at this time, a human hand may be required to assist in order to complete the caulking. After limiting at a plurality of positions, the riveting can be very conveniently carried out without the assistance of hands, and the riveting can be faster.

For example, referring to fig. 4 to 8 in combination, the stopper 300 may include a first stopper 310 and a second stopper 320, and the stopper hole 110 may include a first stopper hole 111 and a second stopper hole 112. The first and second stopper portions 310 and 320 may be oppositely disposed at both sides of the fastener in the first direction X-X. When the adapter terminal 200 is horizontally installed at the bottom of the heat insulation cover 100, the first direction X-X may be a direction on the horizontal plane. The first limiting hole 111 may be connected with the first limiting part 310. The second limiting hole 112 may be connected with the second limiting part 320. So configured, the first and second stop portions 310 and 320 can precisely define the position of the transit terminal 200 relative to the component to be grounded in the first direction X-X so that the transit terminal 200 and the fastening holes (if any) on the component to be grounded can be better aligned.

Although in the illustrated embodiment, the first stop portion 310 and the second stop portion 320 are disposed opposite each other, in other embodiments not shown, the two stop portions may be perpendicular to each other or at other angles to the line of the fastener, respectively.

6-7, along a second direction Y-Y perpendicular to the first direction X-X, a dimension Y1 of the first spacing portion 310 may be adapted to a dimension Y3 of the first spacing hole 111, and a dimension Y2 of the second spacing portion 320 may be adapted to a dimension Y4 of the second spacing hole 112. So configured, in embodiments in which the first and second limiting portions 310 and 320 may be oppositely disposed at both sides of the fastener along the first direction X-X, the limiting portions 300 and the limiting holes 110 may not only achieve accurate alignment of the adaptor terminal 200 and the component to be grounded in the X-X direction; accurate alignment of the patch terminal 200 with the component to be grounded in the Y-Y direction is also achieved by dimension definition in the second direction Y-Y.

Illustratively, as shown in fig. 8, the first stopper 310 may include a first root end 311 and a first head end 314. The first root end 311 may be connected to the adaptor terminal 200 or the component to be grounded where the first limiting portion 310 is located. The first head end 314 is an end distant from the first root end 311. In the illustrated embodiment, the first stopper 310 is disposed on the transit terminal 200. The first root end 311 is connected to the transit terminal 200. As shown in fig. 6, the first limiting hole 111 may have a first inner side edge 111a. The first inner side edge 111a may be adjacent to the second limiting hole 112. Along the first direction X-X, the root end 311 of the first stopper 310 may abut against the first inner side edge 111a. Similarly, as shown in fig. 8, the second stop 320 may include a second root end 321 and a second head end 324. The second root end 321 may be connected to the adaptor terminal 200 or the component to be grounded where the second limiting portion 320 is located. In the illustrated embodiment, the second root end 321 is connected to the transit terminal 200. Second head end 324 is the end remote from second root end 321. As shown in fig. 6, the second limiting aperture 112 may have a second inner side edge 112a. The second inner edge 112a may be adjacent to the second limiting aperture 112. Along the first direction X-X, the root end 321 of the second limiting portion 320 may abut against the second inner side edge 112a. In the assembly process, the bottom of the heat insulation cover 100 is upwards and horizontally placed, then the first head end 314 of the first limiting part 310 and the second head end 324 of the second limiting part 320 are aligned with the first limiting hole 111 and the second limiting hole 112 respectively, the switching terminal 200 falls on the heat insulation cover 100 under the action of gravity until the root end 311 of the first limiting part 310 and the second root end 321 of the second limiting part 320 are abutted to the first inner side edge 111a of the first limiting hole 111 and the second inner side edge 112a of the second limiting hole 112 respectively, and thus, the position of the switching terminal 200 can be accurately limited on the heat insulation cover 100.

Illustratively, as shown in FIG. 8, along a first direction X-X, the first head end 314 may be remote from the fastener relative to the first root end 311. So set up, in the in-process that first spacing portion 310 inserted first spacing hole 111, first head end 314 of being convenient for inserts first spacing hole 111 more conveniently, first head end 314 can not scratch first inboard edge 111a of first spacing hole 111, avoids producing the influence to spacing precision. Also, the first limiting hole 111 may be set larger in size along the first direction X-X, whereby alignment of the first head end 314 with the first limiting hole 111 may be facilitated.

Illustratively, along a first direction X-X, the second head end 324 may be remote from the fastener relative to the second root end 321. So set up, in the in-process that second spacing portion 320 inserted second spacing hole 112, second head end 324 of being convenient for inserts second spacing hole 112 more conveniently, second head end 324 can not scratch second inboard edge 112a of second spacing hole 112, avoids producing the influence to spacing precision. Also, the second limiting aperture 112 may be sized larger along the first direction X-X, whereby alignment of the second head end 324 with the second limiting aperture 112 may be facilitated.

Further, as shown in fig. 8, the first stopper 310 may further include a first insertion section 313 and a first guide section 312. The first insertion section 313 and the first guide section 312 may be connected between the first root end 311 and the first head end 314. The first guide section 312 may be connected between the first insertion section 313 and the first root end 311. The first insertion section 313 is remote from the fastener relative to the first root end 311. The first guide section 312 may extend obliquely or in an arc shape with respect to the first insertion section 313. It can be appreciated that when the first limiting portion 310 is inserted into the first limiting hole 111, the first head end 314 first extends into the first limiting hole 111, then the first inserting section 313 is gradually inserted into the first limiting hole 111, and then the first guiding section 312 is also inserted into the first limiting hole 111, during the insertion process, because the first guiding section 312 may extend obliquely or have an arc shape with respect to the first inserting section 313, the first guiding section 312 may play a guiding role during the insertion process, and further position the adaptor terminal 200.

Further, as shown in fig. 8, the second stopper 320 may further include a second insertion section 323 and a second guide section 322. Second insertion section 323 and second guide section 322 may be connected between second root end 321 and second head end 324. The second guide section 322 may be connected between the second insertion section 323 and the second root end 321. The second insertion section 323 is remote from the fastener relative to the second root end 321. The second guide section 322 may extend obliquely or in an arc shape with respect to the second insertion section 323. It can be appreciated that when the second limiting portion 320 is inserted into the second limiting hole 112, the second head end 324 first extends into the second limiting hole 112, then the second inserting section 323 is gradually inserted into the second limiting hole 112, and then the second guiding section 322 is also inserted into the second limiting hole 112, during the inserting process, because the second guiding section 322 may extend obliquely or have an arc shape with respect to the second inserting section 323, the second guiding section 322 may play a guiding role during the inserting process, and further position the transit terminal 200.

Illustratively, along the first direction X-X, a dimension X3 (see fig. 6) of the first spacing hole 111 may be greater than a distance X1 (see fig. 8) of the first head end 314 to the first root end 311. In this way, the alignment requirement of the first limiting portion 310 and the first limiting hole 111 along the first direction X-X can be reduced, and the first head end 314 can be prevented from being smoothly inserted into the first limiting hole 111 due to deformation.

Illustratively, a dimension X4 (see FIG. 6) of the second limiting aperture 112 is greater than a distance X2 (see FIG. 8) from the second head end 324 to the second root end 321 along the first direction X-X. By this arrangement, the alignment requirement of the second limiting portion 320 and the second limiting hole 112 along the first direction X-X can be reduced, and the second head end 324 can be prevented from being inserted into the first limiting hole 111 smoothly due to deformation. When X3 is greater than X1 and/or X4 is greater than X2, the adaptor terminal 200 is allowed to be less aligned with the heat insulation cover 100 along the first direction X-X, so that the first and second limiting portions 310 and 320 can be inserted into the first and second limiting holes 111 and 112, respectively, so that the assembly is more convenient and faster.

For example, referring to fig. 6 and 7 in combination, the aperture D2 of the second fastening hole 101 may be larger than the aperture D1 of the first fastening hole 201. In some alternative embodiments, D1 may be 0.2-0.3mm. Preferably, D1 is 0.25mm. In some alternative embodiments, D2 may be 0.3-0.4mm. Preferably, D2 is 0.35mm. When the aperture D2 of the second fastening hole 101 is larger than the aperture D1 of the first fastening hole 201, even if the centers of the first fastening hole 201 and the second fastening hole 101 cannot be aligned accurately, penetration of the fastener into the second fastening hole 101 and the first fastening hole 201 can be ensured, whereby requirements on the machining accuracy of the fastening holes, the limit portion, and the limit accuracy of the limit hole can be reduced.

As illustrated in fig. 4 to 5 and 7 to 9, the transit terminal 200 may include a fixing portion 210 and a connection portion 220 connected to each other, for example. The fixing portion 210 and the connection portion 220 may be integrally formed or separately formed and then connected to each other, which is not limited herein. In some alternative embodiments, the fixing portion 210 may have a plate shape, thus facilitating the manufacturing of the fixing portion 210. The fixing portion 210 may have other structures, which are not limited herein. The stopper 300 may be provided on the fixing portion 210. In some alternative embodiments, the stopper 300 may be provided at an edge region of the fixing portion 210. In other embodiments, not shown, the stopper 300 may be provided in a middle region of the fixing portion 210. A fastener may be coupled to the fixing portion 210. The wiring part 220 may be electrically connected to a ground line. In this way, the charges on the component to be grounded can be transferred to the ground wire through the connection part 220 on the transfer terminal 200, so that the grounding of the component to be grounded is realized, and the risk of electric shock is avoided. The arrangement is that the fastener can be connected to the fixing portion 210, the fixing portion 210 can be used as a bearing carrier when the fastener is fastened, so that no acting force is applied to the wiring portion 220 when the fastener is fastened, the performance of the wiring portion 220 is not influenced by the fastening force of the fastener, and the stability of the performance of the wiring portion 220 is further ensured; the reliability of grounding is improved.

Illustratively, the wire connection 220 may include a plurality of electrical contacts. In some alternative embodiments, the number of the plurality of electrical contacts is three, electrical contact 221, electrical contact 222, and electrical contact 223, respectively. In other embodiments, not shown, the number of electrical contacts may be two, four, or more. One of the plurality of electrical contacts may be electrically connected to ground. At least one of the plurality of electrical contacts may be electrically connected to other components to be grounded, for example, by wires. Other components to be grounded may include inner pot 400, heating assembly 500, temperature sensing assembly 700, and outer housing 600 (if made of a metallic material). For ease of connection, the ends of the wires may be connected with pluggable connectors, through which the wires may be connected with the electrical contacts. Of course, the wires may also be directly electrically connected to the electrical contacts. Illustratively, as shown in FIGS. 8-9, the ground wire 231, the first wire 232 connected to the heating assembly 500, and the second wire 233 connected to the temperature sensing assembly 700 may be connected to one pluggable connector 241, and the third wire 234 connected to the housing 600 may be connected to the other pluggable connector 242. Of course, in other embodiments not shown, the ground wire 231 may be further connected to another pluggable connector (not shown). Alternatively, each of the other components to be grounded and the ground wire 231 may be separately connected to one pluggable connector; any number of them may be used to connect a pluggable connector, and one skilled in the art may reasonably choose how to distribute pluggable connectors to these other components to be grounded and the ground wire 231 as desired. In this way, both the component to be grounded where the transit terminal 200 is located and the other components to be grounded electrically connected to the electrical contacts can be grounded.

For example, as shown in fig. 4 to 5, the wire connection part 220 may extend obliquely from the fixing part 210 toward a direction away from the member to be grounded. Thus, the connection part 220 and the member to be grounded have a certain operation space, so that an operator can conveniently connect the ground wire to the connection part 220. Preferably, as shown in fig. 9, the included angle α between the wire part 220 and the fixing part 210 may be in the range of 110 degrees to 150 degrees. When the included angle α between the connection part 220 and the fixing part 210 is smaller than 110 degrees, the space occupied by the connection part 220 and the wires (or the wires and the pluggable connection member) connected thereto may be excessively large, and in fact, the space in the pot body is very limited. When the angle α between the wire connection part 220 and the fixing part 210 is greater than 150 degrees, it may be inconvenient for the wire (or the wire and the pluggable connector) to be connected with the wire connection part 220. Of course, the scope of the present application does not exclude angles a less than 110 and angles a greater than 150.
