In addition, the heat of the temperature measuring probe 31 is transferred to the thermal link 36 through the heat transfer element 4 in a contact manner, and compared with the conventional radiation heat transfer manner, the temperature of the temperature measuring probe 31 can be quickly and effectively sensed by the thermal link 36, so that the heat transfer efficiency is improved, the reaction speed of the thermal link 36 is increased, the abnormal working time of the cooking appliance is shortened, and the safety performance of the product is improved. And the heat dissipation is slow in a contact heat transfer mode, the temperature transferred to the thermal fuse link 36 is closer to the real temperature of the temperature measuring probe 31, and the detection accuracy and the reaction sensitivity are further improved.

Preferably, the heat transfer member 4 is made of a metal material to have a good heat conduction performance and ensure heat transfer efficiency. Of course, the heat transfer element 4 can also be made of other heat conductive materials, and is not limited in particular.

The heat transfer member 4 includes a first contact portion 41 and a second contact portion 42, the first contact portion 41 contacts the temperature probe 31, and the second contact portion 42 contacts the thermal link 36, but the present invention is not limited to the contact manner between the second contact portion 42 and the thermal link 36, and includes but is not limited to the following embodiments:

the first implementation mode comprises the following steps: in the present embodiment, the second contact portion 42 is located below the thermal link 36. The heat transfer member 4 is more stabilized by pressing the thermal link 36 against the second contact portion 42, and the heat transfer member 4 is prevented from shaking.

The second embodiment: in the present embodiment, as shown in fig. 3 to 4, the second contact portion 42 is located above the thermal fuse link 36 to press-contact the thermal fuse link 36.

The heat transfer member 4 not only has a heat transfer function, but also can compress the thermal fuse 36, and is right the thermal fuse 36 has a compression fixing function, so that the position stability of the thermal fuse 36 is improved, and an additional fixing structure is not required to be arranged for fixing the thermal fuse 36, thereby simplifying the structure inside the control member 3 and saving the cost.

As a preferred example of the present embodiment, as shown in fig. 4, the heat transfer member 4 further includes an extension portion 43 disposed between the first contact portion 41 and the second contact portion 42, and the extension portion 43 is bent in a direction away from the thermostat 35.

The extending portion 43 is bent in a direction away from the temperature controller 35, so that the heat transfer element 4 is prevented from moving away from the temperature controller 35, a gap between the heat transfer element 4 and the temperature controller 35 is increased, a heat dissipation effect of the heat transfer element 4 is improved, heat on the heat transfer element 4 is prevented from being transferred to the temperature controller 35, and the service life of the temperature controller 35 is shortened.

The third embodiment is as follows: in the present embodiment, the second contact portion 42 surrounds the thermal fuse link 36.

The second contact portion 42 surrounds the thermal fuse-link 36, so that the contact area between the second contact portion 42 and the thermal fuse-link 36 is increased, the heat transfer efficiency is improved, and the reaction sensitivity of the thermal fuse-link 36 is improved. For example, as shown in fig. 5, the second contact portion 42 is an annular structure, and the thermal fuse link 36 extends into the interior of the annular structure.

It should be noted that, the present invention does not specifically limit the structure of the inserting portion 34 and the matching portion 11, and preferably, one of the inserting portion 34 and the matching portion 11 is an inserting protrusion, and the other is an inserting groove.

In one embodiment, as shown in fig. 3-4, the insertion part 34 is an insertion groove 341 and the mating part 11 is an insertion protrusion. Of course, the insertion part 34 may also be an insertion protrusion, and correspondingly, the matching part 11 is an insertion groove.

Further, as shown in fig. 4, an opening 342 is formed on the outer circumference of the insertion groove 341.

The arrangement of the opening 342 compensates for the processing errors of the insertion protrusion and the insertion groove 341, and when the diameter of the insertion protrusion is larger and the aperture of the insertion groove 341 is smaller, the insertion groove 341 is more easily deformed due to the opening 342, so that the insertion protrusion can be normally inserted into the insertion groove 341. On the other hand, the opening 342 is provided to help the heat dissipation of the insertion protrusion, and prevent the insertion protrusion and the insertion groove 341 from being deformed or damaged at a high temperature.

Preferably, as shown in fig. 4, a guiding rib position 37 is further disposed inside the control member 3, and the guiding rib position 37 is used for guiding the insertion protrusion to be inserted into the insertion groove 341.

When the insertion protrusion is inserted into the control member 3, it is difficult to insert the insertion protrusion into the insertion groove 341 because a user cannot directly observe the position of the insertion protrusion.

Due to the arrangement of the guide rib positions 37, the insertion protrusions can be guided by the guide rib positions 37, so that a user can feel the contact between the insertion protrusions and the guide rib positions 37 and obtain force feedback, the force feedback is used as guidance, the insertion protrusions and the insertion grooves 341 are smoothly inserted, the insertion difficulty is reduced, and the use experience is improved.

Further, as shown in fig. 4, the guiding rib 37 is located between the temperature measuring probe 31 and the insertion groove 341.

The guide rib positions 37 also have a heat insulation effect, and the insertion groove 341 and the temperature measuring probe 31 are separated in two areas by the guide rib positions 37, so that the temperature of the temperature measuring probe 31 is blocked, and the phenomenon that the temperature measuring probe 31 radiates to the insertion groove 341 to cause the deformation of the insertion groove 341 and influence the service life of the insertion groove 341 is avoided.

As a preferred embodiment of the present invention, as shown in fig. 3, the control member 3 includes a mounting seat 33 and a cover plate 32, the mounting seat 33 has a mounting cavity 331, the cover plate 32 closes the mounting cavity 331, and the cover plate 32 is detachably connected to the mounting seat 33.

The cover plate 32 and the mounting seat 33 are detachably connected, and the mounting cavity 331 can be exposed to the outside, so that the mounting of parts inside the mounting cavity is facilitated.

In this embodiment, the connection between the mounting seat 33 and the cover plate 32 is not specifically limited, and may be fixed by screw connection, clamping connection, magnetic attraction, or the like.

Further, as shown in fig. 4, the mounting seat 33 is provided with a first fixing location 38 and a second fixing location 39, and the first fixing location 38 and the second fixing location 39 are respectively located at two sides of the temperature measuring probe 31.

Because temperature probe 31 stretches out the length of 3 outsides of control is longer, consequently user often is difficult to guarantee to follow all the time in the in-process of pegging graft the axial application of force of temperature probe 31, works as temperature probe 31 receives the power of deviating from the axis direction, then can extrude apron 32 or mount pad 33 makes the connection pine of the two loosen, causes apron 32 local perk.

Two fixed positions are located temperature probe 31 both sides have improved the apron 32 with mount pad 33 is in the joint strength of temperature probe 31 department has improved the stability of the connection here, avoids the apron 32 with mount pad 33 is in temperature probe 31 stretching out position department takes place to loosen.
