[0013] In one embodiment, the second driving member includes an electromagnet and a magnet. The electromagnet is fixed to an end of the second guide rail away from the support plate, and the magnet is fixed to an end of the temperature probe close to the electromagnet.

[0029] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a temperature measuring structure, including a substrate 10, a sealing member 20, a first driving member 30 and a temperature probe 40; the substrate 10 is provided with a temperature measuring groove, the sealing member 20 is fixed in the temperature measuring groove and is tightly fitted with the inner wall of the temperature measuring groove, and the sealing member 20 also has a gap 21 corresponding to the temperature probe 40; the first driving member 30 is fixed to the substrate 10, and the driving end of the first driving member 30 is a supporting plate 31, and the temperature probe 40 is arranged on the supporting plate 31 and passes through the gap 21 to the other side of the substrate 10, so as to drive the temperature probe 40 to move along the length direction of the gap 21 through the first driving member 30.

[0030] In the present application, the temperature probe 40 is driven to move by the first driving member 30, and the temperature detection of multiple positions in the cavity can be completed by only one temperature probe 40, thereby reducing the equipment cost while realizing multi-point temperature measurement; at the same time, the first driving member 30 is arranged on the outside of the substrate 10, and the temperature probe 40 is extended into the inside of the substrate 10 to avoid damage to the first driving member 30 by the high temperature during the cooking process, thereby increasing its service life, and in combination with the sealing member 20 with a gap 21, it is possible to minimize the heat leakage in the cavity without affecting the movement of the temperature probe 40.

[0031] It is worth mentioning that the first driving member 30 here can be a commonly used driving structure such as an electric push rod, a motor-driven screw structure, an electromagnet, etc., as long as it can drive the temperature probe 40 to move along the length direction of the gap 21, and the present application does not make further limitations here.

[0032] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the temperature measuring structure also includes a first guide rail 50, which is fixed to the substrate 10 and parallel to the gap 21, the support plate 31 is slidably connected to the first guide rail 50 along the length direction of the first guide rail 50, and the temperature probe 40 is arranged on the support plate 31.

[0033] The sliding connection between the support plate 31 and the first guide rail 50 can guide the movement of the support plate 31 , thereby increasing the movement stability of the support plate 31 .

[0034] Preferably, the temperature measuring structure includes two first guide rails 50 , the two first guide rails 50 are respectively located on both sides of the gap 21 , and both ends of the support plate 31 are slidably connected to one of the first guide rails 50 .

[0035] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the temperature measuring structure also includes a second driving member, the second driving member is disposed on the support plate 31, and the temperature probe 40 is disposed at the driving end of the second driving member, so that the temperature probe 40 is driven by the second driving member to move in a direction perpendicular to the substrate 10.

[0036] The second driving member can be used to control the depth of the temperature probe 40 in the cavity to increase the measurable temperature range and to more accurately detect the temperatures at different locations inside the cavity.

[0037] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the temperature measurement structure further includes a second guide rail 60 , which is fixed to the support plate 31 and perpendicular to the substrate 10 , and the temperature probe 40 is slidably connected to the second guide rail 60 along a direction perpendicular to the substrate 10 .

[0038] The sliding connection between the temperature probe 40 and the second guide rail 60 can guide the vertical movement of the temperature probe 40 , thereby increasing the movement stability of the temperature probe 40 .

[0039] Preferably, the temperature measurement structure includes two second guide rails 60 , the two second guide rails 60 are respectively located on both sides of the temperature probe 40 , and both ends of the temperature probe 40 are respectively slidably connected to one second guide rail 60 .

[0040] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the second driving member includes an electromagnet 71 and a magnet 72 . The electromagnet 71 is fixed to one end of the second guide rail 60 away from the support plate 31 , and the magnet 72 is fixed to one end of the temperature probe 40 close to the electromagnet 71 .

[0041] As current cooking appliances pursue miniaturization design, relying on the attraction and repulsion characteristics between the electromagnet 71 and the magnet 72, the temperature probe 40 can be driven while occupying a small space, thereby reducing the overall volume of the cooking appliance as much as possible.

[0042] In some other embodiments, the second driving member may also be a commonly used driving structure such as a motor, an electric push rod, a cylinder, etc., as long as it can drive the temperature probe 40 to move in the vertical direction, and the present application does not make any further limitations here.

[0043] In some embodiments, when the second driving member drives the temperature probe 40 to move to the extreme position in a direction away from the substrate 10 , the temperature probe 40 is entirely located on the same side of the sealing member, that is, the temperature probe 40 is completely located outside the chamber.

[0044] It is not difficult to understand that when the temperature probe 40 passes through the gap 21 and extends into the chamber, the sealing member 20 cannot completely isolate the chamber from the outside, and a certain gap is bound to exist in the sealing member 20 where the temperature probe 40 is located due to the deformation of the gap 21;

[0045] The temperature probe 40 is controlled to move vertically by the second driving member, and is extended into the cavity only when temperature measurement is required. After the temperature measurement is completed, the temperature probe 40 is controlled to move as a whole to the outside of the cavity, which can maximize the sealing effect of the seal 20 and reduce heat leakage from the cavity during cooking.

[0046] Please refer to Figure 2 As shown, in some embodiments, the sealing member 20 is a sealing strip having a gap 21 extending therethrough.

[0047] In some other embodiments, the sealing member 20 may also be two sealing strips parallel to each other, with a gap 21 formed between the two sealing strips.

[0048] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the outer peripheral surface of the sealing strip has a concave engaging portion 22, and the engaging portion 22 is engaged with the inner wall of the temperature measuring chamber by snapping the engaging portion 22 with the substrate 10, thereby increasing the sealing performance of the sealing strip and preventing the heat inside the chamber from leaking out through the connection position of the sealing strip.

[0049] A second aspect of the present application provides a cooking appliance comprising the above-mentioned temperature measurement structure.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
