Description

Technical Field

[0001] This utility model belongs to the field of cooking appliance technology, specifically relating to a simple cooking food processor. Background Technology

[0002] To improve the convenience and safety of cooking, existing cooking appliances typically include sensors that automatically detect the connection status of the pot, such as air fryers. However, most traditional designs use complex spring structures to achieve this connection sensing between the pot and the appliance. This structure not only increases the complexity of the overall construction and production costs, but also leads to reduced product stability and durability due to spring aging and deformation. This results in inaccurate pot connection sensing, affecting the normal use of the cooking appliance. In addition, current cooking appliances on the market are generally bulky and have a large amount of unused internal space, which not only wastes materials but also makes them inconvenient to move and store, greatly impacting the user experience. Utility Model Content

[0003] (1) Technical problems to be solved This utility model provides a cooking machine with a simple structure, which aims to solve the problems of complex structure and unstable use of the sensing element used to sense the connection status of the pot in the existing cooking machine, as well as the bulky overall shape, large amount of unused internal space, and inconvenience of transportation and storage of the cooking machine.

[0004] (2) Technical solution This utility model provides a cooking machine with a simple structure, including a body and a pot. A heating zone is provided below the body, and a heating element is provided in the heating zone. The pot is located below the heating element. The body also includes a control component and a sensing component. The sensing component includes a sensor and a floating contact rod. One end of the floating contact rod is in movable contact with the pot, and the other end is in selective contact with the sensor. When the pot body is connected to the machine body, the pot body pushes the floating contact rod to abut against the sensor, and the sensing component and the control component circuit are connected. When the pot body is separated from the machine body, the floating contact rod disengages from the sensor, and the sensing component disconnects from the control component circuit.

[0005] Furthermore, the sensor is provided with an elastic contact that movably abuts against the floating contact rod.

[0006] Furthermore, the floating contact rod extends through the machine body into the heating zone, and the pot edge at the top of the pot body is provided with an abutment portion corresponding to the floating contact rod, the abutment portion being in movable contact with the floating contact rod.

[0007] Furthermore, the body includes a detachably connected shell and an inner support, the inner support having a mounting groove, and the sensor being located within the mounting groove.

[0008] Furthermore, the mounting groove is provided with a through hole penetrating the inner bracket, and the floating contact rod moves up and down in the through hole. The mounting groove is also provided with an annular protrusion around the through hole, and the inner diameter of the annular protrusion is larger than the inner diameter of the through hole, so that an annular step is formed inside the annular protrusion.

[0009] Furthermore, the floating contact rod is provided with a boss that is adapted to the annular step, and the lower end face of the boss is in movable contact with the annular step.

[0010] Furthermore, the heating component includes a heating element, a fan blade assembly, and a driving component. The heating element and the fan blade assembly are located below the inner support, the driving component is located on the inner support and is electrically connected to the control component, and the output shaft of the driving component passes through the inner support and is fixedly connected to the fan blade assembly. The heating element is located below the fan blade assembly and is electrically connected to the control component.

[0011] Furthermore, the housing includes a separable upper shell and a lower shell, the inner diameter of the upper shell is smaller than the inner diameter of the lower shell, and an "L"-shaped fixing frame is provided inside the upper shell, with the driving component located inside the fixing frame.

[0012] Furthermore, the control assembly includes a control panel, a first circuit board, and a second circuit board that are electrically connected to each other. The first circuit board and the second circuit board are screwed to two sides of the mounting bracket, respectively. The control panel is located at the top of the upper shell and is tilted towards the user.

[0013] Furthermore, the upper shell has inwardly recessed gripping portions on both sides, and the surface of the gripping portions has an anti-slip structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. A sensing component is installed. Through the cooperation of the sensing component and the pot body, the machine body can intelligently sense the connection status of the pot body. The sensing component cleverly utilizes the dynamic contact mechanism between the floating contact rod and the sensor. When the pot body is connected to the machine body, the floating contact rod is pushed by the pot body to contact the sensor contact point, triggering the circuit to conduct a signal. When the pot body is separated, the floating contact rod automatically resets under the action of gravity, cutting off the circuit connection. This effectively eliminates the traditional spring structure, which not only simplifies the overall structure and reduces production costs, but also significantly improves the stability and durability of the product, reducing the risk of failure caused by spring aging, deformation, etc.

[0015] 2. The shell is divided into a detachable upper shell and a lower shell, and the inner diameter of the upper shell is smaller than that of the lower shell. This makes the shell shrink from bottom to top, avoiding the waste of space in the upper part of the traditional equal-diameter shell. This makes the overall structure of this utility model more compact and small, saving space and making it easier for users to store and carry. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figure 1-4 As shown, this utility model provides a simple cooking machine, including a body 1 and a pot body 2. A heating zone 13 is provided below the body 1, and a heating element 3 is provided in the heating zone 13. The pot body 2 is located below the heating element 3. The heating element 3 is used to heat the food in the pot body 2 to achieve the cooking function. The machine body 1 is also equipped with a control component 4 and a sensing component 5. The sensing component 5 includes a sensor 51 and a floating contact rod 52. One end of the floating contact rod 52 is in movable contact with the pot body 2, and the other end is selectively in contact with the sensor 51. When the pot body 2 is connected to the machine body 1, the pot body 2 pushes the floating contact rod 52 to contact the sensor 51, and the sensing component 5 is connected to the control component 4. When the pot body 2 is separated from the machine body 1, the floating contact rod 52 is disengaged from the sensor 51, and the sensing component 5 is disconnected from the control component 4. This allows the cooking machine to intelligently sense the connection status of the pot body 2. When the pot body 2 is placed in position, the heating function is automatically activated, and when the pot body 2 is removed, the power is automatically cut off, effectively avoiding misoperation and safety hazards, and improving the convenience and safety of use.

[0031] In this embodiment, the sensor 51 is a micro switch, and the sensor 51 is provided with an elastic contact 511 that movably abuts against the floating contact rod 52, so that the sensing component 5 is more sensitive to the position change of the pot body 2 and can more accurately realize the circuit connection and disconnection.

[0032] Specifically, the floating contact rod 52 extends through the body 1 into the heating zone 13. The pot edge at the top of the pot body 2 is provided with an abutment part 21 corresponding to the floating contact rod 52. The abutment part 21 abuts against the floating contact rod 52, ensuring a stable and reliable connection and separation between the pot body 2 and the floating contact rod 52.

[0033] Furthermore, such as Figure 4-6 As shown, the body 1 includes a detachably connected housing 11 and an inner support 12. The sensor 51 is located between the housing 11 and the inner support 12 and is fixedly connected to the inner support 12. The inner support 12 is provided with a mounting groove 121, and the sensor 51 is located in the mounting groove 121 to ensure the stability of the sensor 51's position and prevent the sensor 51 from becoming loose, which would affect the accuracy of the sensing. The heating zone 13 is located below the inner support 12 and is separated from the area where the sensor 51 is located, to prevent the heat in the heating zone 13 from becoming too high and damaging the sensor 51 due to high temperature, thus extending the service life of the sensor 51.

[0034] Furthermore, the mounting groove 121 is provided with a through hole 122 penetrating the inner bracket 12. The floating contact rod 52 moves up and down within the through hole 122. An annular protrusion 123 is also provided around the through hole 122 within the mounting groove 121. The inner diameter of the annular protrusion 123 is larger than the inner diameter of the through hole 122, forming an annular step 124 inside the annular protrusion 123. The floating contact rod 52 is provided with a boss 521 that matches the annular step 124. The lower end face of the boss 521 movably abuts against the annular step 124. During installation, the... The floating contact rod 52 is inserted downward from the mounting groove 121 into the through hole 122, so that the boss 521 abuts against the annular step 124. Since the inner diameter of the annular step 124 is larger than the inner diameter of the through hole 122, the floating contact rod 52 will not slip out of the through hole 122 under the support of the annular step 124. Next, the sensor 51 is placed into the mounting groove 121, so that the sensor 51 abuts against the end face of the annular protrusion 123. At this time, the contact point 511 is located in the annular protrusion 123 and corresponds to the through hole 122. When the pot body 2 is separated from the machine body 1, the floating contact rod 52 is not driven by external force. Under the action of gravity, its protrusion 521 and the annular step 124 remain in contact, so that the floating contact rod 52 and the contact point 511 are separated. At this time, the circuit of the sensing component 5 and the control component 4 is disconnected, and the cooking machine stops heating. When the pot body 2 is connected to the machine body 1, the abutment part 21 at the top of the pot body 2 pushes the floating contact rod 52 upward, so that the protrusion 521 of the floating contact rod 52 slides upward within the annular protrusion 123 and separates from the annular step 124 until the top of the floating contact rod 52 abuts against the contact point 511 of the sensor 51. At this time, the circuit of the sensing component 5 and the control component 4 is connected, and the cooking machine starts to heat up.

[0035] By providing an annular protrusion 123 and an annular step 124 on the through hole 122 and a matching boss 521 on the floating contact rod 52, the structure not only limits the sliding of the floating contact rod 52, preventing it from slipping due to vibration or external force during use, but also enhances the stability of the floating contact rod 52 within the through hole 122, ensuring that the floating contact rod 52 can accurately contact and separate from the contact point 511 of the sensor 51, thereby improving the sensitivity and reliability of the sensing component 5. Moreover, unlike the existing technology that uses a spring to achieve the connection sensing between the pot body and the machine body, this utility model does not require the use of a spring component, which simplifies the overall structure, reduces production costs and assembly difficulty, and also reduces the failure rate caused by spring aging, deformation and other problems, further improving the stability and durability of the product.

[0036] Furthermore, such as Figure 7 As shown, the heating component 3 includes a heating element 31, a fan blade assembly 32, and a driving component 33. The heating element 31 and the fan blade assembly 32 are located below the inner support 12. The driving component 33 is located on the inner support 12 and is electrically connected to the control component 4. The output shaft of the driving component 33 passes through the inner support 12 and is fixedly connected to the fan blade assembly 32. The heating element 31 is located below the fan blade assembly 32 and is electrically connected to the control component 4. In use, the control component 4 controls the driving component 33 to work. The driving component 33 drives the fan blade assembly 32 to rotate, so that the airflow generated by the rotation of the fan blade assembly 32 blows the heat generated by the heating element 31 evenly onto the pot body 2, so that the food in the pot body 2 can be heated evenly and the cooking effect is better.

[0037] Preferably, to prevent excessive heat from the heating element 31 from being conducted to the drive component 33 and the control component 4 during operation, thus affecting their normal operation and service life, the fan blade assembly 32 includes a first impeller 321 and a second impeller 322. A heat insulation cover 14 is also provided below the inner support 12. The second impeller 322 and the heating element 31 are located inside the heat insulation cover 14, and the first impeller 321 is located between the heat insulation cover 14 and the inner support 12, so that the heat insulation cover 14 and the interior of the pot body 2 enclose the heating zone 13. A heat dissipation zone 15 is formed between the top of the heat insulation cover 14 and the shell 11. The first impeller 321 is located in the heat dissipation zone 15 to accelerate the air flow speed in the heat dissipation zone 15 and improve the heat dissipation effect. The second impeller 322 is located in the heating zone 13 to accelerate the air flow speed in the heating zone 13, so that the heat generated by the heating element 31 can be transferred to the pot body 2 more quickly and evenly, further improving the cooking effect.

[0038] Preferably, such as Figure 8 As shown, the housing 11 is also provided with heat dissipation holes 16. Part of the heat dissipation holes 16 are connected to the heating zone 13 and part are connected to the heat dissipation zone 15, so that some of the heat in the heating zone 13 can be dissipated through the heat dissipation holes 16 to avoid the temperature in the heating zone 13 from being too high; at the same time, it can also allow the air in the heat dissipation zone 15 to exchange with the outside air, further enhancing the heat dissipation effect and ensuring that the cooking machine can maintain stable performance during long-term use.

[0039] Furthermore, such as Figure 9 As shown, the housing 11 includes a separable upper shell 111 and a lower shell 112. The inner diameter of the upper shell 111 is smaller than the inner diameter of the lower shell 112, causing the outer shape of the housing 11 to taper from bottom to top. This allows for a more compact internal structure, making the food processor of this invention more refined and unique compared to traditional food processors with uniform top and bottom dimensions. The upper shell 111 contains an "L"-shaped fixing bracket 113, and the driving component 33 is located inside the fixing bracket 113. The fixing bracket 113 provides fixation and support for the driving component 33, preventing it from shaking during operation and reducing noise, thus improving the user experience.

[0040] Furthermore, the control component 4 includes a control panel 41, a first circuit board 42, and a second circuit board 43 electrically connected to each other. The first circuit board 42 and the second circuit board 43 are screwed to two sides of the mounting bracket 113, forming an "L" shape. This makes efficient use of the space on both sides of the mounting bracket 113, resulting in a more compact overall structure. The control panel 41 is located at the top of the upper shell 111 and is tilted towards the user, allowing the user to clearly see the information on the control panel 41 during operation without bending over or adjusting the viewing angle, thus improving the convenience and comfort of operation. Simultaneously, the tilted design of the control panel 41 also helps to prevent water droplets or oil stains from directly dripping onto it, extending the service life of the control panel 41.

[0041] Furthermore, such as Figure 10 As shown, since the pot body 2 is located below the machine body 1, the pot body 2 provides support for the machine body 1. When cooking is complete, the user needs to grasp the machine body 1 to separate the machine body 1 from the pot body 2. To facilitate the user's grip, the upper shell 111 has inwardly recessed grip portions 114 on both sides. The surface of the grip portions 114 is provided with an anti-slip structure 115. The anti-slip structure 115 is specifically a number of grooves distributed in strip, dot, or polygonal shapes. These grooves can increase the friction between the user's fingers and the grip portions 114. Even if the user's hands are wet or oily, they can firmly grip the machine body 1, effectively preventing the hand from slipping when separating the machine body 1 from the pot body 2, further improving the safety and convenience of use.

[0042] Preferably, such as Figure 9 As shown, the lower end face of the housing 11 is also provided with a plurality of protruding feet 116 extending toward the pot body 2. In this embodiment, the protruding feet 116 are respectively arranged on the four opposite corners of the housing 11, so that after the machine body 1 is separated from the pot body 2, the machine body 1 can avoid direct contact with the table surface under the support of the protruding feet 116, preventing water stains or dirt on the table surface from contaminating the bottom of the machine body 1, making the cooking process more hygienic, and also reducing the friction between the bottom of the machine body 1 and the table surface, making it easier for the user to move the machine body 1 for cleaning or storage.

[0043] like Figure 11-12As shown, in some embodiments, the body 1 further includes an extension frame 6, which is snapped and fixed to the body 1. The radial dimension of the extension frame 6 is larger than that of the body 1 to form a radially outward-expanding support plane, thereby increasing the volume of the heating zone 13. This allows the body 1 to accommodate larger pots 2, meeting diverse cooking needs. The snap-fit ​​connection between the extension frame 6 and the body 1 makes installation simple and disassembly extremely easy, allowing users to adjust flexibly according to actual needs. When a larger pot 2 is required for cooking, simply install the extension frame 6 onto the body 1 to expand the effective area of ​​the heating zone 13, ensuring that the larger pot 2 is heated evenly. At this time, the contact part 21 that abuts against the floating contact rod 52 is located on the extension frame 6. When the larger pot 2 is not needed, the extension frame 6 can be removed, and the body 1 can return to its original compact and elegant form, facilitating storage and not occupying excessive space.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
