The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0022] The cooking device 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] According to the cooking device 1000 of the embodiment of the present invention, Figure 1 As shown, it includes: a box body 100 and a detection component 200, the box body 100 includes a cavity wall 1, the cavity wall 1 participates in defining a cooking cavity 100a, the detection component 200 includes a mounting sleeve 2, a detection probe 3 and a driving device 4, the mounting sleeve 2 is fixedly mounted on the cavity wall 1, the driving device 4 is used to drive the detection probe 3 to move along the axial direction of the mounting sleeve 2, so that the detection probe 3 can extend out of or retract into the mounting sleeve 2, and the detection probe 3 can extend out of the mounting sleeve 2 relative to the mounting sleeve 2 by moving toward the center direction of the cooking cavity 100a and appear in the cooking cavity 100a.

[0024] The housing 100 is the main body of the cooking device 1000. The housing 100 defines a cooking cavity 100a, which is used to accommodate and cook food. The detection component 200 is used to detect the temperature in the cooking cavity 100a, so that the temperature of the cooking cavity 100a can be detected in real time, so as to adjust the temperature in the cooking cavity 100a, realize accurate temperature control, and improve the cooking effect.

[0025] The detection component 200 includes a mounting sleeve 2, a detection probe 3 and a driving device 4. The mounting sleeve 2 plays a supporting and fixing role. The mounting sleeve 2 is fixed relative to the cooking cavity 100a. The driving device 4 can drive the detection probe 3 to extend and retract along the mounting sleeve 2, that is, the detection probe 3 can move relative to the cooking cavity 100a, so that the detection probe 3 can achieve multi-point sampling in the cooking cavity 100a, improving the accuracy of temperature detection. In addition, the detection probe 3 can be retracted into the mounting sleeve 2, thereby reducing the space occupied by the cooking cavity 100a and facilitating the access of food to the cooking cavity 100a.

[0026] It is understandable that the heating element of the cooking device 1000 is arranged on the cavity wall 1, so there is a temperature difference between the temperature at the center of the cooking cavity 100a and the temperature of the cooking cavity 100a near the cavity wall 1. In the related art, there is a temperature difference between the temperature detected by the detection probe near the cavity wall and the actual temperature of the food in the cooking cavity, which can easily cause the food cooking to fail to meet expectations. The present invention drives the detection probe 3 to move and extend toward the center of the cooking cavity 100a, which can not only realize multi-point sampling of the detection probe 3 in the cooking cavity 100a, but also detect the temperature closer to the center of the cooking cavity 100a, thereby improving the problem of large deviation between the temperature detected by the detection probe 3 and the actual temperature of the food, and improving the working reliability of the cooking device 1000.

[0027] In addition, by setting up the mounting sleeve 2, the detection probe 3 is movable compared to the mounting sleeve 2, and the detection limit position of the detection probe 3 is the superposition of the length of the detection probe 3 and the mounting sleeve 2, so that the detection probe 3 can be closer to the center of the cooking cavity 100a, thereby improving the accuracy of temperature detection and further improving the working reliability of the cooking device 1000.

[0028] The driving device 4 includes: an extending driving mechanism 4a and a retracting driving mechanism 4b. The extending driving mechanism 4a is used to drive the detection probe 3 to extend the mounting sleeve 2, and the retracting driving mechanism 4b is used to drive the detection probe 3 to retract the mounting sleeve 2. One of the retracting driving mechanism 4b and the extending driving mechanism 4a includes an elastic member 421 to utilize elastic force to drive the detection probe 3 to move.

[0029] By providing the elastic member 421 to utilize elastic force to drive the detection probe 3 to move, external drive energy consumption and drive control can be omitted, thereby reducing costs.

[0030] According to the cooking device 1000 of the embodiment of the present invention, by setting the mounting sleeve 2 to be fixedly connected to the cavity wall 1, the detection probe 3 can be extended and retracted toward the center of the cooking cavity 100a compared with the mounting sleeve 2, and the temperature closer to the center of the cooking cavity 100a can be detected, thereby improving the accuracy of temperature detection. In addition, by superimposing the lengths of the mounting sleeve 2 and the detection probe 3, the detection probe 3 can be closer to the center of the cooking cavity 100a, thereby improving the accuracy of detection, thereby improving the working reliability of the cooking device 1000.

[0031] In some embodiments, the mounting sleeve 2 is installed through the cavity wall 1 .

[0032] Since the detection probe 3 needs to have telescopic movement, compared with only setting the detection probe to move relative to the cavity wall, the present invention is provided with a mounting sleeve 2, and the mounting sleeve 2 passes through the cavity wall 1 and is fixed, which can easily achieve the sealing of the connection between the detection component 200 and the cavity wall 1, and can improve the reliability problem caused by the leakage of steam, temperature or electromagnetic waves in the cooking cavity 100a from the installation point.

[0033] The installation sleeve 2 passes through the cavity wall 1 and is fixed, which makes it easy to achieve sealing at the connection between the detection component 200 and the cavity wall 1, and can improve the reliability problem caused by leakage of steam, heat or electromagnetic waves in the cooking cavity 100a from the installation point.

[0034] Optionally, the cooking device 1000 may be a kitchen appliance such as an oven or a steam oven.

[0035] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the mounting sleeve 2 includes a mounting portion 21 and a sleeve portion 22. The mounting portion 21 is located outside the cavity wall 1 and is mounted on the cavity wall 1. The sleeve portion 22 passes through the mounting hole 11 on the cavity wall 1 and the outer end of the sleeve portion 22 is connected to the mounting portion 21, and the inner end of the sleeve portion 22 extends into the cooking cavity 100a.

[0036] like Figure 2 and Figure 3 As shown, the mounting sleeve 2 is penetrated by the mounting hole 11 along the outer edge of the box body 100 through the cavity wall 1, the mounting portion 21 is located on the outer side of the cavity wall 1 and cooperates with the cavity wall 1 to limit the mounting sleeve 2, the sleeve portion 22 is penetrated by the mounting hole 11, and the detection probe 3 extends out of or retracts the mounting sleeve 2 from the inner end of the sleeve portion 22.

[0037] By providing the mounting sleeve 2 with the mounting portion 21 for installation, the mounting sleeve 2 is easy to install and seal. The sealing method of the mounting sleeve 2 is not limited. For example, the mounting portion 21 may cover the sealing mounting hole 11; or the sleeve portion 22 may be sealed with the mounting hole 11. The specific sealing method may be selected according to actual needs.

[0038] In some embodiments of the present invention, Figure 2 As shown, the mounting portion 21 covers the sealing mounting hole 11 .

[0039] The cross-sectional area of ​​the mounting portion 21 is much larger than the mounting hole 11 on the cavity wall 1. After the mounting portion 21 cooperates with the cavity wall 1, it covers the sealing mounting hole 11, thereby achieving the sealing of the connection between the detection component 200 and the cavity wall 1. The sealing method of the mounting portion 21 covering the sealing mounting hole 11 is simple, and the sealing of the connection between the detection component 200 and the cavity wall 1 can be completed by passing the mounting sleeve 2 through and installing it on the cavity wall 1.

[0040] In some embodiments of the present invention, the sleeve portion 22 is sealingly matched with the mounting hole 11 .

[0041] Optionally, the sleeve portion 22 and the mounting hole 11 fit tightly together; or, further optionally, the sleeve portion 22 and the cavity wall 1 are sealed and connected via a seal, thereby achieving sealing at the connection between the detection component 200 and the cavity wall 1 .

[0042] In some embodiments of the present invention, Figure 2 As shown, a fixing hole is opened on the mounting portion 21 , and a fastener passes through the fixing hole and is fixedly connected to the cavity wall 1 , thereby fixing the mounting sleeve 2 to the cavity wall 1 .

[0043] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the detection component 200 also includes: a movable sleeve 5, which is inserted into the mounting sleeve 2 and movable along the axial direction of the mounting sleeve 2 so as to be telescopically movable relative to the mounting sleeve 2. The movable sleeve 5 can extend out of the mounting sleeve 2 and be exposed in the cooking cavity 100a by moving toward the center direction of the cooking cavity 100a relative to the mounting sleeve 2.

[0044] like Figure 2 As shown, the detection probe 3 is inserted into the movable sleeve 5 and is movable along the axial direction of the movable sleeve 5 so as to be telescopically movable relative to the mounting sleeve 2. The detection probe 3 can extend out of the movable sleeve 5 and be exposed in the cooking cavity 100a by moving toward the center direction of the cooking cavity 100a relative to the movable sleeve 5.

[0045] The movable sleeve 5 can move axially relative to the installation sleeve 2, and can be extended relative to the installation sleeve 2 toward the center of the cooking cavity 100a. The movable sleeve 5 can be retracted in the installation sleeve 2 or extended from the installation sleeve 2 and exposed in the cooking cavity 100a. The detection probe 3 can move axially relative to the movable sleeve 5, and can be extended relative to the movable sleeve 5 toward the center of the cooking cavity 100a. The detection probe 3 can be retracted in the movable sleeve 5 or extended from the movable sleeve 5 and exposed in the cooking cavity 100a.

[0046] By superimposing the three lengths of the installation sleeve 2, the movable sleeve 5 and the detection probe 3, the detection probe 3 can be closer to the center of the cooking cavity 100a, so that the detection probe 3 has a larger moving range, and the detection accuracy of the detection probe 3 is improved. In addition, the length of each section can be shortened. When the detection probe 3 is retracted into the movable sleeve 5 and the movable sleeve 5 is retracted into the installation sleeve 2, the overall length is shorter, further reducing the occupation of the cooking cavity 100a.

[0047] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, a first sealing convex ring 31 extending radially is provided at one end of the detection probe 3 close to the mounting sleeve 2, and the radial end face of the first sealing convex ring 31 is in close contact with the inner wall of the movable sleeve 5; when the detection probe 3 is extended to the extreme position, the axial end face of the first sealing convex ring 31 away from the mounting sleeve 2 abuts against the axial end face of the movable sleeve 5.

[0048] The movable sleeve 5 is a hollow tube for the detection probe 3 to pass through and move, and the detection probe 3 is provided with a first sealing convex ring 31. When the detection probe 3 moves relative to the movable sleeve 5, the first sealing convex ring 31 always keeps in close contact with the inner wall of the movable sleeve 5, thereby improving the sealing of the connection between the detection probe 3 and the movable sleeve 5, and improving the reliability problem caused by the leakage of steam, heat or electromagnetic waves in the cooking cavity 100a from the connection between the detection probe 3 and the movable sleeve 5.

[0049] It is worth noting that the radial end face of the first sealing convex ring 31 is in close contact with the inner wall of the movable sleeve 5 in a broad sense, and the radial end face of the first sealing convex ring 31 can be close to the movable sleeve 5 to reduce the gap between the first sealing convex ring 31 and the inner wall of the movable sleeve 5, thereby improving the sealing performance of the connection between the detection probe 3 and the movable sleeve 5, and also allowing the detection probe 3 to move smoothly. Alternatively, the radial end face of the first sealing convex ring 31 contacts the movable sleeve 5, further improving the sealing performance of the connection between the detection probe 3 and the movable sleeve 5.

[0050] The first sealing convex ring 31 is arranged at one end of the detection probe 3 close to the mounting sleeve 2. When the detection probe 3 is extended from the movable sleeve 5 to the limit position, the first sealing convex ring 31 abuts against the axial end surface of the movable sleeve 5. On the one hand, the contact area between the first sealing convex ring 31 and the movable sleeve 5 can be increased, and a mutually perpendicular double seal is formed between the first sealing convex ring 31 and the movable sleeve 5, further improving the sealing performance of the connection between the detection probe 3 and the movable sleeve 5; on the other hand, the abutment and cooperation between the axial end surfaces of the first sealing convex ring 31 and the movable sleeve 5 can limit the detection probe 3, so that the detection probe 3 has an extreme extension position relative to the movable sleeve 5, and the movement stability of the detection probe 3 is improved.

[0051] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, a second sealing convex ring 51 extending radially is provided at one end of the movable sleeve 5 close to the mounting sleeve 2, and the radial end surface of the second sealing convex ring 51 is in contact with the inner wall of the mounting sleeve 2; when the movable sleeve 5 is extended to the extreme position, the axial end surface of the second sealing convex ring 51 away from the mounting sleeve 2 is in contact with the axial end surface of the mounting sleeve 2.

[0052] The mounting sleeve 2 is a hollow tube for the movable sleeve 5 to pass through and move, and the movable sleeve 5 is provided with a second sealing convex ring 51. During the movement of the movable sleeve 5 relative to the mounting sleeve 2, the second sealing convex ring 51 always keeps in close contact with the inner wall of the mounting sleeve 2, thereby improving the sealing of the connection between the movable sleeve 5 and the mounting sleeve 2, and improving the reliability problem caused by the leakage of steam, heat or electromagnetic waves in the cooking cavity 100a from the connection between the movable sleeve 5 and the mounting sleeve 2.

[0053] It is worth noting that the radial end face of the second sealing convex ring 51 is in close contact with the inner wall of the mounting sleeve 2 in a broad sense, and the radial end face of the second sealing convex ring 51 can be close to the mounting sleeve 2 to reduce the gap between the second sealing convex ring 51 and the inner wall of the mounting sleeve 2, thereby improving the sealing performance of the connection between the movable sleeve 5 and the mounting sleeve 2, and also allowing the movable sleeve 5 to move smoothly. Alternatively, the radial end face of the second sealing convex ring 51 contacts the mounting sleeve 2, further improving the sealing performance of the connection between the movable sleeve 5 and the mounting sleeve 2.

[0054] The second sealing convex ring 51 is arranged at one end of the movable sleeve 5 close to the mounting sleeve 2. When the movable sleeve 5 is extended from the mounting sleeve 2 to the limit position, the second sealing convex ring 51 abuts against the axial end surface of the mounting sleeve 2. On the one hand, the contact area between the second sealing convex ring 51 and the mounting sleeve 2 can be increased, and a mutually perpendicular double seal is formed between the second sealing convex ring 51 and the mounting sleeve 2, further improving the sealing performance of the connection between the movable sleeve 5 and the mounting sleeve 2; on the other hand, the abutment and cooperation between the second sealing convex ring 51 and the axial end surface of the mounting sleeve 2 can limit the movable sleeve 5, so that the movable sleeve 5 has a limit extension position relative to the mounting sleeve 2, and the movement stability of the movable sleeve 5 is improved.

[0055] In some embodiments of the present invention, the detection component 200 can increase the detection range of the detection probe 3 by superimposing the three lengths of the installation sleeve 2, the movable sleeve 5 and the detection probe 3, and can also reduce the space occupied by the detection component 200 in the cooking cavity 100a. By providing the first sealing convex ring 31 and the second sealing convex ring 51, effective sealing can be achieved, thereby improving the reliability problem caused by the leakage of steam, heat or electromagnetic waves in the cooking cavity 100a from the detection component 200.

[0056] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the movable sleeve 5 is a whole tubular structure, and the movable sleeve 5 as a whole is movable relative to the axial direction of the mounting sleeve 2. The detection component 200 increases the detection range of the detection probe 3 by superimposing the lengths of the mounting sleeve 2, the movable sleeve 5 and the detection probe 3. When the detection component 200 is retracted to the extreme position, the length of the detection component 200 located in the cooking cavity 100a is the sum of the length of the mounting sleeve 2 located in the cooking cavity 100a, the length of the portion of the movable sleeve 5 not retracted into the mounting sleeve 2, and the length of the portion of the detection probe 3 not retracted into the movable sleeve.

[0057] In other embodiments of the present invention, the movable sleeve 5 includes at least two telescopic sections that can be sequentially sleeved.

[0058] Taking the movable sleeve 5 including two telescopic sections as an example, the movable sleeve 5 includes a first telescopic section and a second telescopic section, the second telescopic section is inserted through the first telescopic section, and is movable along the axial direction of the first telescopic section to telescopically move relative to the first telescopic section. The first telescopic section is connected to the installation sleeve 2, and the second telescopic section is connected to the detection probe 3, and the detection probe 3 can telescopically move relative to the second telescopic section.

[0059] By designing the movable sleeve 5 as a retractable first telescopic section and a second telescopic section, the detection component 200 can further increase the detection range of the detection probe 3 by superimposing the four lengths of the mounting sleeve 2, the first telescopic section, the second telescopic section and the detection probe 3. Compared with the movable sleeve 5 as a whole, the length of the second telescopic section retracted into the first telescopic section is shorter, and correspondingly, the length of the fixed sleeve can also be shortened to retract the first telescopic section with a reduced length, so that the detection component 200 occupies a smaller space in the accommodating cavity when it is retracted to the extreme position.

[0060] The movable sleeve 5 may further include more telescopic sections, and the length and number of the telescopic sections may be specifically selected according to the size of the cooking cavity 100a.

[0061] In some embodiments of the present invention, Figure 7 As shown, more than half of the length of the moving sleeve 5 can be retracted into the mounting sleeve 2 , and more than half of the length of the detection probe 3 can be retracted into the moving sleeve 5 .

[0062] When the detection component 200 is retracted to the limit position, the overall length is shorter, which can reduce the space occupied by the cooking cavity 100a.

[0063] In some embodiments of the present invention, Figure 2 As shown, the length L2 of the movable sleeve 5 is 0.8 to 1.2 times the length L1 of the installation sleeve 2 , and the length L3 of the detection probe 3 is 0.8 to 1.2 times the length L1 of the installation sleeve 2 .

[0064] The installation sleeve 2 is fixed relative to the cooking cavity 100a, so the length of the installation sleeve 2 remains unchanged during the contraction and extension of the detection component 200. The length L2 of the movable sleeve 5 is designed to be 0.8 to 1.2 times the length L1 of the installation sleeve 2, and the movable sleeve 5 can be completely retracted into the installation sleeve 2 or at least half of it can be retracted into the installation sleeve 2 when it is contracted; the length L3 of the detection probe 3 is designed to be 0.8 to 1.2 times the length L1 of the installation sleeve 2, and can be completely retracted into the installation sleeve 2 or at least half of it can be retracted into the installation sleeve 2 when it is contracted. When the detection component 200 is retracted to the extreme position, the overall length is shorter, which can reduce the space occupied by the cooking cavity 100a.

[0065] In some embodiments of the present invention, Figure 7As shown, when the movable sleeve 5 is retracted to the extreme position in the mounting sleeve 2 and the detection probe 3 is retracted to the extreme position in the movable sleeve 5 , the detection head of the detection probe 3 is located outside the movable sleeve 5 and the mounting sleeve 2 .

[0066] During the process of contraction and extension of the detection probe 3, the detection body of the detection probe 3 is always exposed in the cooking cavity 100a. The detection probe 3 can always detect the temperature in the cooking cavity 100a, reduce the measurement error caused by the obstruction of the installation sleeve 2 or the movable sleeve 5, and improve the detection accuracy of the detection probe 3.

[0067] In some embodiments of the present invention, Figure 1 As shown, the detection component 200 is configured so that the detection head of the detection probe 3 can reach the center of the cooking cavity 100a.

[0068] The heating element of the cooking device 1000 is arranged on the cavity wall 1, so there is a temperature difference between the temperature at the center of the cooking cavity 100a and the temperature near the cavity wall 1 of the cooking cavity 100a, and this temperature difference can reach 25°C. The detection head of the detection probe 3 of the embodiment of the present invention can reach the center of the cooking cavity 100a, and the sampling temperature value is accurate, thereby improving the problem of large deviation between the temperature detected by the detection probe 3 and the actual temperature of the food. Precise temperature control can be achieved, and the heating program can be controlled in real time without heating delay. As a result, the cooking of various dishes can be accurately heated and cooled to achieve the expected cooking color, softness, hardness and taste. At the same time, the need for other temperature sensors can be reduced to reduce the cost and structural complexity of the product.

[0069] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the detection component 200 has a limiting structure 6, which enables the detection probe 3 to have an extreme extension position relative to the mounting sleeve 2. At the extreme extension position, the detection head of the detection probe 3 can reach the center of the cooking cavity 100a.

[0070] By providing the limiting structure 6 , the detection probe 3 can be limited at the extreme extension position relative to the mounting sleeve 2 , thereby improving the working reliability of the detection probe 3 .

[0071] When the detection component 200 is in the extreme extended position, the detection head of the detection probe 3 reaches the center of the cooking cavity 100a, and the detection head of the detection probe 3 will not exceed the center position, which can improve the damage caused by the collision between the detection head of the detection probe 3 and the tray in the cooking cavity 100a.

[0072] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the detection component 200 also includes: a movable sleeve 5, which is inserted into the mounting sleeve 2 and is movable along the axial direction of the mounting sleeve 2 so as to be telescopically movable relative to the mounting sleeve 2. The detection probe 3 is inserted into the movable sleeve 5 and is movable along the axial direction of the movable sleeve 5 so as to be telescopically movable relative to the mounting sleeve 2.

[0073] The limiting structure 6 includes a first limiting structure 61 for limiting the detection probe 3 at the extreme extension position relative to the movable sleeve 5 , and a second limiting structure 62 for limiting the movable sleeve 5 at the extreme extension position relative to the mounting sleeve 2 .

[0074] like Figure 5 As shown, the first limiting structure 61 includes a first sealing convex ring 31 which is arranged at one end of the detection probe 3 close to the mounting sleeve 2 and extends radially outward, and the first limiting structure 61 also includes a first limiting end 52 which is arranged at one end of the movable sleeve 5 away from the mounting sleeve 2 and extends radially inward. When the detection probe 3 is extended to the extreme position, the first sealing convex ring 31 abuts against the first limiting end 52 on the axial surface.

[0075] like Figure 6 As shown, the second limiting structure 62 includes a second sealing convex ring 51 which is arranged at one end of the movable sleeve 5 close to the mounting sleeve 2 and extends radially outward, and the second limiting structure 62 also includes a second limiting end 221 which is arranged at one end of the mounting sleeve 2 close to the center of the cooking cavity 100a and extends radially inward. When the movable sleeve 5 is extended to the extreme position, the second sealing convex ring 51 abuts against the second limiting end 221 on the axial surface.

[0076] In addition, when the detection probe 3 is retracted into the movable sleeve 5 to the limit position, the first sealing convex ring 31 also abuts against the axial end surface of the movable sleeve 5 close to the mounting sleeve 2, thereby limiting the detection probe 3. When the movable sleeve 5 is retracted into the mounting sleeve 2 to the limit position, the second sealing convex ring 51 also abuts against the axial end surface of the mounting sleeve 2 close to the cavity wall 1.

[0077] In some embodiments of the present invention, Figure 1 As shown, the cavity wall 1 is the top wall of the cooking cavity 100a, and the detection probe 3 can extend out of the mounting sleeve 2 by moving downward relative to the mounting sleeve 2.

[0078] By fixing the mounting sleeve 2 on the top wall of the cooking cavity 100a, the extension of the detection component 200 is not easily interfered, and the detection head of the detection probe 3 can easily reach the center of the cooking cavity 100a.

[0079] In some other embodiments of the present invention, the cavity wall 1 may also be the bottom wall of the cooking cavity 100a, and the detection probe 3 may extend out of the mounting sleeve 2 by moving upward relative to the mounting sleeve 2.

[0080] In some further embodiments of the present invention, the cavity wall 1 may also be a side wall of the cooking cavity 100a.

[0081] In some embodiments of the present invention, Figure 2 and Figure 7 As shown, the driving device 4 is configured to drive the detection probe 3 to reciprocate between the first position m and the second position n, and to allow the detection probe 3 to stay at any position between the first position m and the second position n.

[0082] When the detection probe 3 is at the first position m, the detection probe 3 is at the extreme extended position relative to the mounting sleeve 2 , and when the detection probe 3 is at the second position n, the detection probe 3 is retracted to the extreme position in the mounting sleeve 2 .

[0083] The detection probe 3 can stay at any position between the first position m and the second position n. The detection probe 3 can choose the extension position according to the placement position of the food in the cooking cavity 100a, which can improve the damage caused by the detection head of the detection probe 3 colliding with the tray or food in the cooking cavity 100a and enhance the working stability of the detection probe 3.

[0084] In some embodiments of the present invention, when the detection probe 3 is at the first position m, the detection head of the detection probe 3 reaches the center of the cooking cavity 100a.

[0085] In some embodiments of the present invention, when the detection probe 3 is driven to move by the driving device 4, the detection head of the detection probe 3 is always exposed in the cooking cavity 100a.

[0086] The detection probe 3 can always detect the temperature in the cooking cavity 100 a , reduce the measurement error caused by being blocked by the installation sleeve 2 , and improve the detection accuracy of the detection probe 3 .

[0087] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the driving device 4 includes: an extension driving mechanism 4a and a retraction driving mechanism 4b. The extension driving mechanism 4a is used to drive the detection probe 3 to extend out of the installation sleeve 2, and the retraction driving mechanism 4b is used to drive the detection probe 3 to retract into the installation sleeve 2.

[0088] In some embodiments of the present invention, the retracting drive mechanism 4b and the extending drive mechanism 4a are the same mechanism. By providing the same mechanism to drive the detection probe 3 to extend and retract the installation sleeve 2, the structure can be simplified.

[0089] The retracting drive mechanism 4b and the extending drive mechanism 4a are the same set of mechanisms. Exemplarily, the retracting drive mechanism 4b and the extending drive mechanism 4a can be gear racks, worm gears, hydraulic cylinders, electric cylinders, pneumatic cylinders, etc.

[0090] In other embodiments of the present invention, Figure 2 and Figure 3 As shown, the retracting driving mechanism 4 b and the extending driving mechanism 4 a are two different mechanisms, and one of the retracting driving mechanism 4 b and the extending driving mechanism 4 a includes an elastic member 421 to drive the detection probe 3 to move by utilizing elastic force.

[0091] One of the retracting driving mechanism 4b and the extending driving mechanism 4a has a power source to drive the detection probe 3 to extend or retract, and the other of the retracting driving mechanism 4b and the extending driving mechanism 4a includes an elastic member 421, and the elastic member 421 drives the detection probe 3 to extend or retract. By utilizing the elastic force of the elastic member 421, the external drive energy consumption and drive control of the detection probe 3 to extend or retract can be omitted, the manufacturing cost can be reduced, and the working reliability of the driving device 4 can be improved.

[0092] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the driving device 4 includes: a first driving mechanism 41, the first driving mechanism 41 includes a driving motor 411 and a linkage assembly 412, the driving motor 411 is installed outside the cavity wall 1, and the linkage assembly 412 is respectively connected to the driving motor 411 and the detection probe 3, so that the driving motor 411 drives the detection probe 3 to move through the linkage assembly 412.

[0093] The drive motor 411 is installed outside the cooking cavity 100a, which can reduce the impact on the drive motor 411 and improve the working reliability of the drive motor 411. The drive motor 411 is connected to the linkage component 412, and the linkage component 412 is connected to the detection probe 3. The linkage component 412 can drive the detection probe 3 to move under the drive of the drive motor 411.

[0094] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the first driving mechanism 41 is a retraction driving mechanism 4b, and the linkage assembly 412 includes a reel 4121 and a cable 4122. The reel 4121 is connected to the driving motor 411, one end of the cable 4122 is connected to the reel 4121, and the other end of the cable 4122 is connected to the detection probe 3. The driving motor 411 drives the reel 4121 to reel in the cable 4122, so as to pull the detection probe 3 through the cable 4122 to retract the mounting sleeve 2.

[0095] The wire reel 4121 of the linkage assembly 412 is connected to the driving motor 411, the cable 4122 of the linkage assembly 412 is connected to the detection probe 3, and the cable 4122 is wound on the wire reel 4121. Figure 2 and Figure 3As shown, the installation sleeve 2 is a hollow tube, and the cable 4122 extends from the outside of the cavity wall 1 along the installation sleeve 2 into the installation sleeve 2 to be connected with the detection probe 3.

[0096] In some embodiments of the present invention, Figure 4 As shown, a cable buckle 32 is provided at one end of the detection probe 3 close to the installation sleeve 2 , and a cable 4122 is tied to the cable buckle 32 to pull the detection probe 3 to retract into the installation sleeve 2 .

[0097] In some embodiments of the present invention, Figure 3 and Figure 8 As shown, the linkage assembly 412 also includes a mounting seat 4123, the wire reel 4121 is disposed in the mounting seat 4123, the motor shaft 4111 of the driving motor 411 passes through the mounting seat 4123 and the wire reel 4121, and the motor shaft 4111 rotates with the mounting seat 4123 through the bearing 413.

[0098] The driving motor 411 drives the cable reel 4121 to rotate to reel in and unwind the cable 4122 . The cable reel 4121 is disposed in a mounting seat 4123 and can rotate relative to the mounting seat 4123 . The mounting seat 4123 plays a supporting and fixing role, thereby improving the working reliability of the cable reel 4121 .

[0099] The motor shaft 4111 of the driving motor 411 passes through the mounting seat 4123 and the wire reel 4121. The motor shaft 4111 sets the wire reel 4121 and the mounting seat 4123 at a distance. The motor shaft 4111 rotates with the mounting seat 4123 through the bearing 413, so that the motor shaft 4111 and the wire reel 4121 on the motor shaft 4111 can rotate smoothly relative to the mounting seat 4123.

[0100] In some embodiments of the present invention, Figure 3 and Figure 8 As shown, the motor shaft 4111 of the motor passes through the wire reel 4121, and the wire reel 4121 and the motor shaft 4111 are matched through a key 414 or a non-circular surface transmission, thereby limiting the synchronous rotation of the motor shaft 4111 and the wire reel 4121, thereby improving the working stability of the driving mechanism.

[0101] In some embodiments of the present invention, Figure 3 and Figure 8 As shown, a threaded groove is provided on the peripheral wall surface of the cable reel 4121 to facilitate the cable 4122 to be wound around the cable reel 4121 .

[0102] In some embodiments of the present invention, Figure 4 and Figure 7As shown, the elastic member 421 is fitted between the installation sleeve 2 and the detection probe 3 to drive the detection probe 3 to extend out of or retract into the installation sleeve 2 through elastic force.

[0103] By providing the elastic member 421 to drive the detection probe 3 to move by elastic force, external drive energy consumption and drive control can be omitted, thereby reducing costs. Optionally, the elastic member 421 can drive the detection probe 3 to extend out of the installation sleeve 2; or, alternatively, the elastic member 421 can drive the detection probe 3 to retract into the installation sleeve 2.

[0104] In some embodiments of the present invention, Figure 4 and Figure 7 As shown, the driving device 4 includes: a second driving mechanism 42, which is an elastic member 421 and is fitted between the installation sleeve 2 and the detection probe 3 to drive the detection probe 3 to extend out of the installation sleeve 2 through elastic force.

[0105] By arranging the elastic member 421 to drive the detection probe 3 to extend out of the installation sleeve 2, the external drive energy consumption and drive control for the detection probe 3 to extend out of the installation sleeve 2 can be omitted, thereby reducing the cost.

[0106] It is worth noting that the second driving mechanism 42 is not limited to using the elastic member 421 , and the elastic force of the elastic member 421 itself is used to save the external driving energy consumption and driving control of the detection probe 3 extending out of the mounting sleeve 2 .

[0107] Exemplarily, the second driving mechanism 42 may also be a magnetic component, and utilizes the magnetic force of the magnetic component to drive the detection probe 3 to extend out of the mounting sleeve 2 .

[0108] For example, the second driving mechanism 42 may be omitted. For example, the detection component 200 is arranged at the top, and the detection probe 3 may be driven to extend out of the mounting sleeve 2 by gravity; or for another example, the detection component 200 is arranged at the bottom, and the detection probe 3 may be driven to retract into the mounting sleeve 2 by gravity.

[0109] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the first drive mechanism 41 is a retracting drive mechanism 4b, and the second drive mechanism 42 is an extending drive mechanism 4a. Figure 2 As shown, when the detection probe 3 extends out of the mounting sleeve 2 to the limit position, the elastic member 421 is in a natural state; Figure 7As shown, the driving motor 411 drives the cable reel 4121 to reel in the cable 4122. When the cable 4122 pulls the detection probe 3 to retract the mounting sleeve 2, the elastic member 421 is compressed, and the elastic member 421 has an elongation movement tendency to drive the detection probe 3 to extend out of the mounting sleeve 2. Alternatively, in other embodiments of the present invention, the first driving mechanism 41 may be an extension driving mechanism 4a, and the second driving mechanism 42 may be a retraction driving mechanism 4b.

[0110] Please refer to the following Figure 2-Figure 7 The working process of the detection component 200 according to some specific embodiments of the present invention is described.

[0111] The detection component 200 includes: a mounting sleeve 2, a movable sleeve 5 and a detection probe 3. The mounting sleeve 2 is fixedly mounted on the cavity wall 1. The movable sleeve 5 is inserted through the mounting sleeve 2 and is movable along the axial direction of the mounting sleeve 2 so as to be telescopically movable relative to the mounting sleeve 2. The detection probe 3 is inserted through the movable sleeve 5 and is movable along the axial direction of the movable sleeve 5 so as to be telescopically movable relative to the mounting sleeve 2.

[0112] The detection probe 3 can reciprocate between the first position m and the second position n, so that the detection probe 3 can be dynamically adjusted between the first position m and the second position n in real time according to monitoring needs. When the detection probe 3 is at the first position m, the detection probe 3 is at the extreme extension position relative to the mounting sleeve 2, and the detection head of the detection probe 3 reaches the center of the cooking cavity 100a; when the detection probe 3 is at the second position n, the detection probe 3 retracts to the extreme position in the mounting sleeve 2.

[0113] The driving device 4 includes a retraction driving mechanism 4b, which includes a driving motor 411, a reel 4121 and a cable 4122. The cable 4122 passes through the mounting sleeve 2 and the movable sleeve 5 and is connected to the detection probe 3. The driving motor 411 drives the reel 4121 to reel in the cable 4122, so as to pull the detection probe 3 through the cable 4122 to retract the mounting sleeve 2.

[0114] The retraction process of the detection component 200 is as follows: the detection probe 3 is pulled to first retract into the movable sleeve 5, and is limited when it reaches the end of the movable sleeve 5; then the cable 4122 continues to pull the detection probe 3, and the detection probe 3 and the movable sleeve 5 are retracted toward the installation sleeve 2 together, and are limited when the movable sleeve 5 reaches the end of the installation sleeve 2, at which time the retraction process of the detection component 200 is completed. In this process, the detection probe 3 can stay at any position between the first position m and the second position n.

[0115] The driving device 4 further includes an extension driving mechanism 4a, which is an elastic member 421, and both ends of the elastic member 421 are respectively connected to the mounting sleeve 2 and the detection probe 3. The elastic member 421 is compressed during the retraction process of the detection component 200, and when the detection probe 3 is located at the second position n, the elastic member 421 is compressed to the maximum.

[0116] The extension process of the detection component 200 is as follows: the driving motor 411 drives the cable reel 4121 to release the cable 4122, and the elastic member 421 extends to provide thrust to extend the detection probe 3, and is limited when the detection probe 3 reaches the other end of the movable sleeve 5; then the detection probe 3 drives the movable sleeve 5 to move together and extend out of the installation sleeve 2, and is limited when the movable sleeve 5 reaches the other end of the installation sleeve 2, and the extension process of the detection component 200 is completed. In this process, the detection probe 3 can stay at any position between the first position m and the second position n.
