Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, and in particular to a stirring device and a cooking appliance. Background Technology

[0002] With the development of cooking appliance technology, more and more cooking appliances are beginning to be equipped with temperature detection devices. These devices help adjust the heating temperature to ensure better cooking results. By placing the temperature sensing elements around or at the bottom of the pot, the temperature of the pot can be accurately reflected, which improves the temperature control effect to a certain extent.

[0003] However, temperature sensing elements placed on the pot body cannot accurately reflect the temperature of the food inside. Often, the temperature of the food near the pot body is much higher than that of the food in the center of the pot, affecting the cooking effect. In existing technologies, temperature sensing elements placed inside the pot can measure the temperature of the food inside the pot relatively accurately. However, the temperature sensing elements are usually located at the bottom of the pot body or at a low position above the bottom. When measuring the temperature while stirring the food, the temperature of the food in the upper part still cannot be accurately measured. Furthermore, the temperature sensing elements inside the pot are in motion. Temperature data transmission is usually carried out using wireless transmission elements. However, the environment inside the pot is complex, and the stability of wireless transmission is poor. Using wires for wiring provides high stability, but the wiring is difficult to run and is prone to tangling, affecting the accuracy and stability of temperature data transmission. Utility Model Content

[0004] Therefore, it is necessary to provide a stirring device and cooking appliance to address the problems of inaccurate temperature measurement and poor stability of temperature data transmission in traditional cooking appliances.

[0005] A stirring device for cooking appliances includes a stirring element, a temperature measuring component, a sealing component, and a driving device. The stirring element has a receiving groove and a limiting groove extending from the receiving groove to one end of the stirring element. The temperature measuring component includes a temperature measuring element and a wire fixedly connected to the temperature measuring element. The temperature measuring element is disposed in the receiving groove, and the wire is disposed in the limiting groove. The sealing component is disposed on the stirring element to seal the receiving groove and the limiting groove. The driving device is connected to the other end of the stirring element away from the limiting groove to drive the stirring element to rotate.

[0006] With this configuration, the drive unit drives the stirring component to repeatedly agitate within the cooking appliance, maximizing contact with all parts of the food. The placement of the receiving slot allows the temperature sensing element to move along with the stirring component, thereby accurately measuring the temperature of the food at different locations. The wire is located within the limiting slot, and the sealing component seals both the receiving slot and the limiting slot. Furthermore, the drive unit is connected to the other end of the stirring component away from the limiting slot, enabling the temperature sensing element to transmit temperature data accurately and stably through the wire. This avoids the influence of complex environments on the temperature sensing component, resulting in high accuracy and stability in temperature measurement.

[0007] In one embodiment, the stirring component further includes a plurality of limiting blocks spaced apart along the limiting groove, each limiting block and the limiting groove forming a limiting hole, through which the wire passes.

[0008] With this configuration, the limiting block and the limiting groove form a limiting hole, through which the wire passes. This allows the wire to maintain a relatively fixed position as it moves with the stirring component, preventing it from detaching from the limiting groove and affecting the stability of the temperature sensing element's data transmission.

[0009] In one embodiment, the outer surface of the seal and the outer surface of the agitator form a continuous surface.

[0010] This design allows the seal to completely seal the agitator and the receiving and limiting grooves on it, preventing interference from the complex environment during the agitation process and effectively improving the stability of the temperature measuring component during operation.

[0011] In one embodiment, the agitator bends and extends from both ends toward the middle, and the receiving groove is located in the middle of the agitator.

[0012] With this design, the mixing element bends and extends from both ends toward the middle, allowing it to contact the food in all parts of the cooking appliance to the greatest extent possible during rotation. The temperature sensing element is located in the receiving groove in the middle of the mixing element, enabling it to directly contact the food within the maximum range, thereby more accurately measuring the overall temperature of the food in the cooking appliance and improving the accuracy of temperature measurement.

[0013] In one embodiment, a signal processor is also included, which is electrically connected to the temperature sensing element via a wire.

[0014] With this setup, the signal processor can directly convert the data from the temperature sensing element into a temperature display via wires, enabling dynamic detection of the temperature inside the cooking appliance.

[0015] In one embodiment, a connecting shaft is also included, to which the stirring element is rotatably connected. The connecting shaft is fixedly connected to the signal processor, and the connecting shaft is provided with a positioning hole through which a wire passes.

[0016] With this configuration, the end of the stirring component is rotatably connected to the connecting shaft, which is fixedly connected to the signal processor. This allows the stirring component to rotate relative to the signal processor, preventing possible interference from the signal processor's movement. The connecting shaft is equipped with a positioning hole, allowing the wire to pass through the positioning hole and connect to the signal processor, thus achieving stable transmission of temperature measurement data.

[0017] In one embodiment, the signal processor includes an integrated board, a support, and a contact. The integrated board is disposed on the support and is used to process signals transmitted by wires. The support is snapped onto the contact and forms a battery compartment with the contact for placing a battery. The contact is connected to the wire.

[0018] With this configuration, the signal processor can be powered by a battery to form a standalone unit. Through the integrated board and contacts, it can directly display or wirelessly transmit the data from the temperature sensing components, thus achieving dynamic temperature detection.

[0019] In one embodiment, the temperature sensing element is an NTC thermistor.

[0020] With this configuration, the NTC thermistor has a fast response speed and high stability, ensuring accurate temperature detection. It is also small in size and has a wide range of applications, making it suitable for stirring pieces of different sizes.

[0021] In one embodiment, the seal is a silicone sealant.

[0022] With this configuration, silicone parts can be mass-produced through injection molding, resulting in high production efficiency, good product precision, and low cost. It also enables complete sealing of the mixing components and the receiving and limiting grooves on the mixing components, avoiding the influence of complex environments on the temperature measuring components.

[0023] This application also provides a cooking appliance, including a pot body and a stirring device as described above, wherein the stirring element is rotatably mounted on the pot body.

[0024] This setup enables accurate, stable, and continuous monitoring of the temperature of the food inside the pot, thus improving cooking results. Attached Figure Description

[0038] See Figure 1 , Figure 1 A schematic diagram of a stirring device according to an embodiment of this application is shown. The stirring device is used in a cooking appliance 70 and includes a stirring element 10, a temperature measuring component 20, a sealing component 30, and a driving device 40. The stirring element 10 is provided with a receiving groove 100 and a limiting groove 200 extending from the receiving groove 100 to one end of the stirring element 10. The temperature measuring component 20 includes a temperature measuring element 21 and a wire 22 fixedly connected to the temperature measuring element 21. The temperature measuring element 21 is disposed in the receiving groove 100, and the wire 22 is disposed in the limiting groove 200. The sealing component 30 is disposed on the stirring element 10 to seal the receiving groove 100 and the limiting groove 200. The driving device 40 is connected to the other end of the stirring element 10 away from the limiting groove 200 and is used to drive the stirring element 10 to rotate.

[0039] For details, please refer to Figures 1 to 4As shown, the stirring device is used in the cooking appliance 70. Driven by the drive device 40, it repeatedly stirs within the cooking appliance 70, maximizing contact with all parts of the food. The temperature sensing element 21 is located within the receiving groove 100 on the stirring component 10, allowing it to move with the stirring component 10 and directly measure the temperature of the food at different locations. The wire 22 is fixedly connected to the temperature sensing element 21, ensuring stable transmission of temperature data and preventing potential interruptions in data transmission. The sealing component 30 seals the receiving groove 100 and the limiting groove 200, and the drive device 40 is connected to the other end of the stirring component 10 away from the limiting groove 200. This allows the temperature sensing element to accurately and stably transmit temperature data through the wire 22, avoiding the influence of complex environments on the temperature sensing component 20 and effectively ensuring the accuracy and stability of temperature detection.

[0040] In this embodiment, the stirring component 10 also includes a plurality of limiting blocks 11 spaced apart along the limiting groove 200. Each limiting block 11 and the limiting groove 200 form a limiting hole 300, and the wire 22 passes through the limiting hole 300.

[0041] For details, please refer to Figure 4 As shown, the limiting block 11 and the limiting groove 200 form a limiting hole 300. The wire 22 passes through the limiting hole 300, so that the wire 22 can maintain a relatively fixed position during the movement with the stirring component 10, and avoid the wire 22 from leaving the limiting groove 200 and affecting the stability of the data transmission of the temperature measuring element 21.

[0042] In this embodiment, the outer surface of the seal 30 and the outer surface of the agitator 10 form a continuous surface.

[0043] For details, please refer to Figure 2 As shown, the sealing element 30 covers and encloses the stirring element 10 and the receiving groove 100 and limiting groove 200 on the stirring element 10, so as to avoid interference from complex environments such as liquids, fumes and collisions during the stirring process, and effectively improve the stability of the temperature measuring element 20 during operation.

[0044] Similarly, in other embodiments, the sealing element 30 can also cover or wrap the receiving groove 100 and the limiting groove 200 separately, as long as the temperature measuring element 21 and the wire 22 can be sealed to avoid interference from the complex environment during the stirring process. The specific arrangement will not be described in detail, but the specific arrangement can be referred to the arrangement of the sealing element 30 described above.

[0045] In this embodiment, the stirring element 10 bends and extends from both ends toward the middle, and the receiving groove 100 is located in the middle of the stirring element 10.

[0046] For details, please refer to Figures 1 to 5As shown, the two ends of the stirring element 10 are located on the same axis. The stirring element 10 extends and bends from both ends along the bending direction of the pot body 71 toward the middle, so that when the stirring element 10 rotates around the axis, it can contact the food in all parts of the cooking appliance 70 to the greatest extent. The temperature measuring element 21 is located in the receiving groove 100 in the middle of the stirring element 10, so that the temperature measuring element 21 can directly contact the food within the maximum range, thereby more accurately measuring the overall temperature of the food in the cooking appliance 70 and improving the accuracy of temperature measurement.

[0047] Similarly, in other embodiments, the two ends of the stirring element 10 can be arranged on the axis at different positions, and the stirring element 10 can also be bent and extended towards the middle in other directions. The receiving groove 100 can also be located between the middle position and the end position of the stirring element 10, as long as the stirring element 10 can rotate around the axis and the temperature measuring element 21 in the receiving groove 100 can follow the rotation of the stirring element 10 to contact the ingredients at different positions in the pot. The specific arrangement will not be described in detail. The specific arrangement can be referred to the above arrangement of the stirring element 10 and the receiving groove 100.

[0048] In this embodiment, a signal processor 50 is also included, which is electrically connected to the temperature measuring element 21 via a wire 22.

[0049] For details, please refer to Figures 1 to 5 As shown, the stirring handle 80 is sleeved on the outside of the signal processor 50. The signal processor 50 can directly convert the data of the temperature sensing element 21 into a temperature display through the wire 22, thereby realizing the dynamic detection of the temperature inside the cooking appliance 70. The detection process is highly stable and has a fast response speed.

[0050] In this embodiment, a connecting shaft 60 is also included. The stirring component 10 is rotatably connected to the connecting shaft 60. The connecting shaft 60 is fixedly connected to the signal processor 50. The connecting shaft 60 is provided with a positioning hole 400, through which the wire 22 passes.

[0051] For details, please refer to Figure 4 and Figure 5 As shown, the connecting shaft 60 is threaded to fix the signal processor 50 and the stirring handle 80 outside the signal processor 50. The connecting shaft 60 is provided with a positioning hole 400, which is connected to the limiting hole 300, so that the wire 22 can be restricted within the range of the positioning hole 400, thereby improving the stability of the connection between the wire 22 and the signal processor 50 and ensuring the stable transmission of temperature measurement data.

[0052] Similarly, in other embodiments, the connecting shaft 60 can be connected to the signal processor 50 by welding, snap-fitting, or other methods, as long as it can ensure that the wire 22 is confined within a certain range when the stirring component 10 rotates around the shaft, thus ensuring a stable connection between the wire 22 and the signal processor 50. The specific arrangement will not be described in detail, but the specific arrangement can be referred to the arrangement of the connecting shaft 60 described above.

[0053] In this embodiment, the signal processor 50 includes an integrated board 51, a support 52, and a contact 53. The integrated board 51 is disposed on the support 52 and is used to process the signal transmitted by the wire 22. The support 52 is engaged with the contact 53 and forms a battery compartment 500 with the contact 53. The battery compartment 500 is used to place the battery 600. The contact 53 is connected to the wire 22.

[0054] For details, please refer to Figure 5 As shown, the contact 53 can transfer the energy of the battery 600 in the battery compartment 500 to the integrated board 51, so that the signal processor 50 can become a single unit and display temperature data without external power supply, realize dynamic temperature detection, and improve the application scenarios of the stirring device.

[0055] Similarly, in other embodiments, the integrated board 51 may also be equipped with a Bluetooth chip or a wireless data transmission module, which can not only ensure the stability of the temperature data source, but also improve the diversity of the data displayed, and adapt to a wide range of scenarios.

[0056] To ensure the accuracy of the temperature sensing element 21, in this embodiment, the temperature sensing element 21 is an NTC thermistor.

[0057] For details, please refer to Figures 1 to 5 As shown, NTC thermistors have a fast response speed and high stability, which can ensure the accuracy of temperature detection. They are also small in size and have a wide range of applications, making them suitable for stirring pieces of different sizes.

[0058] Similarly, in other embodiments, the temperature sensing element 21 can be an RTD platinum resistance temperature sensor, a thermocouple, or other temperature sensor, as long as it can achieve the accuracy and sensitivity of temperature measurement. The specific arrangement will not be described in detail, but the specific arrangement can be referred to the arrangement of the temperature sensing element 21 described above.

[0059] It is worth mentioning that in other embodiments, the sensor located in the receiving groove 100 may also be a viscosity sensor or other sensors, which is not limited here.

[0060] In this embodiment, the seal 30 is a silicone sealant.

[0061] For details, please refer to Figure 2As shown, silicone parts can be mass-produced through injection molding, which has high production efficiency, good product precision and low cost. It can achieve complete sealing of the stirring part 10 and the receiving groove 100 and the limiting groove 200 on the stirring part 10, avoiding the influence of complex environment on the temperature measuring component 20.

[0062] See Figure 1 As shown, this application also provides a cooking appliance 70, including a pot body 71 and a stirring device as described above, wherein the stirring element 10 is rotatably mounted on the pot body 71.

[0063] Specifically, such as Figure 1 As shown, the stirring element 10 is located on both sides of the pot body 71. The stirring element 10 can rotate around the axis inside the pot body 71 through the drive device 40, so as to realize accurate, stable and continuous detection of the temperature of the food in different parts of the pot body 71, effectively improving the cooking effect.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0065] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
