The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0027] In order to solve the problem in the prior art that the temperature measuring device of the cooking appliance is not precisely positioned, which affects the measurement accuracy, the present invention provides a cooking appliance.

[0028] like Figures 1 to 4 As shown, the cooking utensil includes a base 10 and a temperature measuring structure 20, the base 10 has an installation space 11, and the installation height of the temperature measuring structure 20 at the installation space 11 is adjustable, wherein the temperature measuring structure 20 includes a guide cylinder 21, a body 22, a temperature measuring piece 23, an elastic element 24 and a heating element, at least a portion of the guide cylinder 21 is arranged in the installation space 11, the installation space 11 and / or the guide cylinder 21 have a plurality of gears arranged along the height direction, the top end of the body 22 extends outward from the guide cylinder 21, the temperature measuring piece 23 is arranged on the body 22, the elastic element 24 is arranged in the guide cylinder 21 to provide a reset force for the body 22 to move upward, and the heating element is arranged in the base 10.

[0029] By setting a plurality of gears in the vertical direction of the installation space 11 and / or the guide cylinder 21, the installation of the temperature measuring structure 20 can be accurately positioned, and the plurality of gears can realize the adjustable installation height of the temperature measuring structure 20 at the installation space 11. The installation position can be flexibly adjusted to ensure sufficient compression, so that the manufacturability and assembly flexibility of the temperature measuring device assembly are large. The setting of the installation space 11 can provide space for the installation of the temperature measuring structure 20. The temperature measuring member 23 is arranged on the main body 22, and the top of the main body 22 is connected to the bottom surface of the inner pot 30. The temperature of the inner pot 30 is transmitted to the temperature measuring member 23, thereby realizing temperature measurement. The elastic element 24 is arranged in the guide cylinder 21 to provide a reset force for the main body 22 to move upward, so that the main body 22 can move up and down relative to the base 10.

[0030] like Figure 2As shown, at least one elastic rib 12 is provided in the installation space 11, and the guide cylinder 21 is fixed in the installation space 11 by the elastic rib 12. The elastic rib 12 and / or the guide cylinder 21 have a plurality of gears arranged in the height direction. The setting of the elastic rib 12 fixes the guide cylinder 21 in the installation space 11, and the elastic rib 12 is elastic, so that the guide cylinder 21 is not fixed, and the distance in the height direction can be adjusted. When the elastic rib 12 is opened, it is convenient to place the guide cylinder 21 and to install the temperature measuring structure 20.

[0031] like Figure 2 As shown, there are two elastic ribs 12, and the two elastic ribs 12 are symmetrically arranged on both sides of the guide cylinder 21. The two elastic ribs 12 are symmetrically arranged on both sides of the guide cylinder 21 so that the force of the guide cylinder 21 in the horizontal direction can be balanced, reducing the movable distance in the horizontal direction and increasing the accuracy of positioning the temperature measuring structure 20.

[0032] like Figure 2 As shown, the outer wall of the guide cylinder 21 is provided with a plurality of slots 211 arranged in sequence along the height direction as a plurality of gears, and the elastic rib 12 has a clamping protrusion 121 that cooperates with the slot 211. The guide cylinder 21 and the slot 211 are an integrated structure, and the elastic rib 12 and the clamping protrusion 121 are also an integrated structure, so that the clamping protrusion 121 and the elastic rib 12 are more tightly connected. The arrangement of the slot 211 and the clamping protrusion 121 allows the installation of the temperature measuring structure 20 to be accurately positioned, and the plurality of gears can realize the adjustable installation height of the temperature measuring structure 20 at the installation space 11, so that the installation position can be flexibly adjusted to ensure sufficient compression.

[0033] like Figure 3 In the specific embodiment shown, the elastic rib 12 includes a horizontal section 122 and a vertical section 123 that are bent in sequence. There is a gap between the vertical section 123 and the inner wall of the installation space 11 to avoid the movement of the vertical section 123, and the clamping protrusion 121 is located on the vertical section 123. The gap between the vertical section 123 and the inner wall of the installation space 11 allows the vertical section 123 to move without wearing the base, and the gap allows the vertical section 123 to have room for movement, so that when the manufactured temperature measurement structure 20 is slightly larger in size, it can also be installed in the installation space 11. When an outward tension is applied to the vertical section 123 of the elastic rib 12, the vertical section 123 can move to the gap, so that the guide cylinder 21 and the base 10 can move up and down relatively. This makes the manufacturability and assembly flexibility of the temperature measurement device assembly large.

[0034] Specifically, the temperature measuring structure 20 is inserted from the bottom of the base 10, and the elastic ribs 12 arranged on the base 10 will elastically deform and open to both sides. When the card slot 211 cooperates with the card connection protrusion 121 on the elastic rib 12, the elastic rib 12 is reset, so that the two parts are stuck and are not easy to fall off.

[0035] like Figure 2 As shown, when the engaging protrusion 121 cooperates with the bottom-end engaging groove 211 among the plurality of engaging grooves 211, the bottom of the guide cylinder 21 extends out from the installation space 11. The guide cylinder 21 is not limited by the installation space 11, so that the installation space 11 can be reasonably miniaturized.

[0036] like Figure 4 As shown, the guide cylinder 21 includes a cylinder 212 and a sealing plate 214, the cylinder 212 has a top opening and a bottom opening, the top opening has a stop convex edge 213 extending toward the center of the top opening, the sealing plate 214 is arranged at the bottom opening and has a avoidance hole, the top end of the body 22 extends upward from the top opening, the bottom end of the body 22 is located at the avoidance hole, the body 22 has a stop boss 221 that stops and cooperates with the stop convex edge 213, and the elastic element 24 abuts between the stop boss 221 and the sealing plate 214. The stop convex edge 213 and the stop boss 221 can stop and cooperate, so that the body 22 and the cylinder 212 are not easy to fall off, which increases the service life of the equipment. The guide cylinder 21 is connected to the sealing plate 214 by screws, buckles or rivets. The elastic element 24 is around the lower end of the body 22, and the setting of the sealing plate 214 not only provides an installation space for the elastic element 24, but also makes the elastic element 24 not easy to separate from the body.

[0037] like Figure 4 As shown, the body 22 includes a large diameter section 222 and a small diameter section 223 connected in sequence, the stop boss 221 is located at the junction of the large diameter section 222 and the small diameter section 223 and protrudes from the outer edge of the large diameter section 222, and the large diameter section 222 is located above the small diameter section 223. The cylinder 212 is sleeved on the outside of the body 22, and the body 22 is set as a variable diameter structure, so that a large space is formed between the cylinder 212 and the small diameter section 223, providing space for the installation of the elastic element 24. The elastic element 24 is wound around the small diameter section 223 of the body 22.

[0038] like Figure 4 As shown, the body 22 has an axially penetrating through hole 224, the temperature measuring element 23 is located at the top of the through hole 224, and the lead 25 connected to the temperature measuring element 23 extends downward through the through hole 224. The top surface of the body 22 is against the bottom surface of the inner pot 30. During operation, the heat of the inner pot 30 is transferred to the body 22, and the body 22 transfers the heat to the temperature measuring element 23. The temperature measuring element 23 is installed at the top of the through hole 224, so that the temperature of the inner pot 30 can be effectively detected.

[0039] Optionally, the cooking utensil is an electric pressure cooker, and of course it can also be other electrical appliances for cooking food, such as an electric rice cooker.
