Description

Technical Field

[0001] The present application relates to the field of food processing, and in particular to a heating plate, a temperature control system and a food processor. Background Art

[0002] As people's living standards continue to improve, many different types of food processors have emerged on the market. Existing food processors use a single thermistor inside the heating plate to detect the heating status of food. However, if ingredients accumulate and are not promptly removed during stirring, the thermistor can become filled with food, resulting in inaccurate temperature measurement and the risk of burning the food. Furthermore, there is a certain lag in the transfer of heat from the heating element to the food, resulting in poor accuracy.

[0003] Therefore, it is necessary to design a heating plate that solves the above technical problems. Utility Model Content

[0004] The purpose of the present application is to provide a heating plate, a temperature control system and a food processor, which prevent the bottom from burning by arranging temperature measuring elements at different positions and adjusting the heating power in real time according to the temperature difference between the two.

[0005] In one aspect, the present application provides a heating plate, comprising:

[0006] A chassis having a heating chamber;

[0007] a heating element, fixed to the chassis; and

[0008] The temperature measuring element includes a first temperature measuring end and a second temperature measuring end. The first temperature measuring end extends through the base plate into the cup, while the second temperature measuring end abuts the base plate. The first temperature measuring end is provided with a first temperature measuring element, while the second temperature measuring end is provided with a second temperature measuring element. Thus, the first temperature measuring element detects the temperature inside the heating chamber, while the second temperature measuring element detects the temperature of the base plate. Based on the temperature difference between the heating chamber and the base plate, the heating power of the heating element is adjusted in real time to prevent a large temperature difference between the inside and outside of the cooking chamber, which can cause the bottom of the cup to burn.

[0009] Furthermore, the chassis includes a chassis and a heat-conducting layer disposed outside the chassis, and the second temperature measuring end is in contact with the chassis or the heat-conducting layer. In this way, the heat can be effectively and evenly dispersed to the surface of the entire chassis through the heat-conducting layer, avoiding local overheating or cooling, thereby ensuring that the food in the chassis can be evenly heated. Particularly, when the second temperature measuring end is in contact with the heat-conducting layer, the temperature change of heating can be reflected more quickly, avoiding lag in the heat transfer process. When the second temperature measuring end is in contact with the chassis, it can ensure that the temperature received by the second temperature measuring element is closer to the actual temperature of the food being measured, thereby improving the reliability of the measurement.

[0010] Furthermore, the heating element is fixed to the side wall of the chassis, and the temperature sensor is installed on the side wall of the chassis. In this way, arranging the temperature sensor on the bottom wall can avoid the influence of direct heating by the heating element. The temperature of the side wall may be relatively high, but it may not accurately reflect the actual temperature of the food inside. The bottom wall can better reflect the working status of the heating plate.

[0011] Furthermore, the second temperature measuring end is located on a side close to the central axis of the chassis, so as to reduce the influence of heat radiation generated by the heating element on the second temperature measuring element and improve the detection accuracy of the second temperature measuring element.

[0012] Furthermore, the first temperature measuring element is a thermistor, an infrared detection device, or a thermocouple; and / or

[0013] The second temperature-measuring element can be a thermistor, infrared detector, or thermocouple. This provides highly accurate temperature data, ensuring precise temperature control during cooking. Thermistors are low-cost; infrared detectors enable non-contact temperature measurement, avoiding potential contamination or damage from direct contact; and thermocouples offer excellent durability in extreme environments, making them suitable for long-term, stable use.

[0014] Furthermore, the heating plate further includes a bracket, the temperature sensor is mounted on the bracket, and the bracket is fixed to the chassis. In this way, the bracket provides a stable mounting base, ensuring that the temperature sensor is not easily moved or detached during use, thereby improving the accuracy and reliability of the measurement.

[0015] Another aspect of the present application provides a temperature control system. The temperature control system includes the above-mentioned heating plate and a control module, wherein the control module is electrically connected to the heating element, the first temperature measuring element, and the second temperature measuring element respectively;

[0016] The control module is configured to obtain the temperature T1 of the first temperature measuring element and the temperature T2 of the second temperature measuring element, and calculate the temperature difference Δt between T1 and T2. The control module is configured to adjust the heating power of the heating element based on the temperature difference Δt. In this way, the temperature control system can adjust the heating power of the heating element based on the temperature difference Δt to prevent the surface of the heating plate from being burnt.

[0017] Another aspect of the present application provides a food processor. The food processor comprises:

[0018] blender cup;

[0019] The blade assembly is assembled at the bottom of the mixing cup, and the blade assembly includes any of the above-mentioned heating plates and a blade assembly mounted on the heating plate. In this way, the blade assembly is used to stir and crush the food in the heating chamber.

[0020] Furthermore, the blending cup includes a cup body and a cup holder disposed at the bottom of the cup body, and the food processor also includes a pressure ring assembly, and the blade disc assembly is detachably mounted to the bottom of the cup body via the pressure ring assembly. Thus, the blade disc assembly is easy to install and remove, and the blade disc assembly is stabilized in the blending cup by the pressure ring assembly.

[0021] Furthermore, the blade disc assembly also includes a blade holder, the heating disc is mounted within the blade holder, the blade assembly includes a blade shaft that passes through the blade holder and the heating disc, and a blade fixed to the blade shaft. A sealing ring is provided between the blade holder and the cup body, and the edge of the heating disc is engaged with the sealing ring. Thus, the provision of the sealing ring forms a seal between the cup body and the blade holder to prevent leakage.

[0022] The present application has the following beneficial effects: the temperature inside the heating cavity is detected by the first temperature measuring element, and the temperature of the bottom plate is detected by the second temperature measuring element, and then the heating power of the heating element can be adjusted in real time according to the temperature difference between the heating cavity and the bottom plate to prevent the bottom from being burnt due to the large temperature difference between the inside and outside of the cooking chamber.

[0037] Reference Figure 1-6 As shown, the present application discloses a heating plate 201, which includes a chassis 10, a heating element 20 and a temperature sensor 30. The chassis 10 has a heating chamber 11, and the heating element 20 is fixed to the chassis 10. The temperature sensor 30 includes a first temperature measuring end 31 and a second temperature measuring end 32, the first temperature measuring end 31 passes through the chassis 10 and extends into the cup, and the second temperature measuring end 32 abuts against the chassis 10; a first temperature measuring element is provided in the first temperature measuring end 31, and a second temperature measuring element is provided in the second temperature measuring end 32. In this way, the temperature in the heating chamber 11 is detected by the first temperature measuring element, and the temperature of the chassis 10 is detected by the second temperature measuring element. Then, according to the temperature difference between the heating chamber 11 and the chassis 10, the heating power of the heating element 20 can be adjusted in real time to prevent the bottom from being burnt due to a large temperature difference between the inside and outside of the cooking.

[0038] The chassis 10 includes a chassis 12 and a heat-conducting layer 13 disposed outside the chassis 12. The heat-conducting layer 13 can effectively and evenly disperse heat to the entire surface of the chassis 12 to avoid local overheating or cooling, thereby ensuring that the food in the chassis 12 can be evenly heated.

[0039] In this application, the heating element 20 is a heating tube, which is fixed to the side wall of the chassis 10. Of course, the heating tube can also be arranged on the bottom wall of the chassis 10. In other embodiments, the heating element 20 can also be a heating film, an infrared heating device, etc. The specific heating device of the chassis 10 is not limited here.

[0040] Example 1:

[0041] Reference Figure 3 As shown, the first temperature measuring end 31 protrudes from the bottom wall of the chassis 10 into the heating chamber 11, and the second temperature measuring end 32 is arranged on the bottom wall of the heat-conducting layer 13, so that the first temperature measuring element and the second temperature measuring element are arranged on the bottom wall, reducing the influence of the heat radiation generated by the heating element 20 on the second temperature measuring element and improving the detection accuracy of the second temperature measuring element.

[0042] Example 2:

[0043] Reference Figure 4 As shown, the first temperature measuring end 31 protrudes from the bottom wall of the chassis 10 into the heating chamber 11, and the second temperature measuring end 32 is disposed on the bottom wall of the heat-conducting layer 13, and the second temperature measuring end 32 is located on a side close to the central axis of the chassis 10. This can further reduce the impact of heat radiation generated by the heating element 20 on the second temperature measuring element in the second temperature measuring end 32, thereby improving the accuracy of the second temperature measuring element's detection.

[0044] Example 3:

[0045] Reference Figure 5 As shown, the first temperature measuring end 31 protrudes from the bottom wall of the chassis 10 into the heating chamber 11, and the second temperature measuring end 32 is arranged on the bottom wall of the disk body 12. The disk body 12 is closer to the heating chamber 11 than the heat-conducting layer 13. By measuring the temperature of the disk body 12, the influence of hysteresis in the heat transfer process can be reduced.

A second temperature measuring terminal 32 is provided on the bottom wall of the chassis 10.

Thermocouples offer excellent durability in extreme environments and are suitable for long-term, stable use.

[0049] In addition, the second temperature measuring element is a thermistor, an infrared detection device, or a thermocouple. This can improve the accuracy of temperature measurement and ensure accurate control of temperature during the cooking process. Thermistors are low-cost.

Thermocouples have good durability in extreme environments and are suitable for long-term stable use. It should be noted that the first temperature measuring element and the second temperature measuring element include but are not limited to the above.

[0054] The blending cup 100 includes a cup body 101 and a cup holder 102 disposed at the bottom of the cup body 101. The blender also includes a pressure ring assembly 300, through which the blade disc assembly 200 is detachably mounted to the bottom of the cup body 101.
