Description

Technical Field

[0001] The present invention relates to the technical field of rice cooker temperature detection, and specifically to a method and device for detecting the temperature of a rice cooker. Background Art

[0002] A rice cooker is a kitchen appliance that uses electrical energy to convert into heat energy for cooking, mainly used for cooking rice, and also has multiple cooking functions such as steaming, boiling, stewing, and simmering. It can not only cook food thoroughly but also keep it warm. It is clean, hygienic, pollution-free, time-saving, and labor-saving, and is one of the indispensable appliances for modern household chores. It is a kitchen appliance that uses electric heating to cook food, and its working temperature is mostly around 100 °C. It can perform various cooking operations such as steaming, boiling, stewing, simmering, and braising. Its core features include automatic heat preservation, timing operation, and precise heating through temperature control. Its basic function is mainly cooking rice, and some models support diversified operations such as making soup and stewing meat. Intelligent rice cookers can adjust the firepower in real time through a computer chip program to improve cooking efficiency and taste. Its basic structure includes an inner pot, a heating plate (or heating wire), a thermostat, and a heat preservation layer. The inner pot is made of various materials, such as stainless steel, ceramic, and purple sand, and some high-end products use a pure iron inner pot to improve the heat conduction performance.

[0003] At present, the commonly used rice cookers on the market do not have an in-pot temperature detection device during the working process, and the temperature control is not precise, resulting in a large difference in the softness of the cooked rice and affecting the taste of the rice. Summary of the Invention

[0004] The purpose of the present invention is to provide a method and device for detecting the temperature inside a rice cooker to precisely control the temperature inside the rice cooker during operation, improve the softness of the rice, and enhance the taste of the rice in order to solve the above technical problems.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A rice cooker temperature detection device includes a temperature sensor, a rice cooker lid, and a rice cooker ECU. Among them, the temperature sensor is the main part of this detection device. The temperature sensor is composed of an NTC thermistor, epoxy resin filling glue, wires, a probe housing, an inner heat shrinkable tube, an outer heat shrinkable tube, a connector, and a sealing ring. The positioning hole of the housing fixing plate of the temperature sensor is fixedly connected to the upper cover of the rice cooker, so that the probe housing of the temperature sensor is hermetically connected to the rice cooker lid through the sealing ring of the temperature sensor, ensuring that the temperature inside the rice cooker does not leak out. The connector of the temperature sensor is connected to the rice cooker ECU to form a rice cooker temperature detection device.

[0006] As a further solution of the present invention: The temperature sensor selects an NTC thermistor with high temperature accuracy and Teflon wire with high temperature resistance. The pins of the NTC thermistor are welded to the core wire of the wire by soldering or resistance welding. For soldering, the soldering iron head touches the pin and the core wire simultaneously, quickly heats up to melt the solder, evenly fills the solder, avoids false soldering or accumulation, and keeps the solder joint stationary and cooling after removing the soldering iron to prevent cracks caused by vibration. For resistance welding, the electrodes apply pressure and generate Joule heat through the current to fuse the pin and the core wire.

[0007] As a further solution of the present invention: The temperature sensor is wrapped with a stainless steel probe housing with high heat conduction efficiency, and a heat-resistant epoxy resin filling adhesive is used to fill and fix the welded NTC thermistor and the probe housing. After the epoxy resin cures, it has high hardness and adhesion, which can effectively resist vibration, impact and mechanical stress, and prevent the NTC thermistor from being displaced or damaged due to external forces.

[0008] As a further solution of the present invention: The two positioning holes of the housing fixing plate of the probe housing are positioned and fixed with the upper cover of the rice cooker to ensure the accurate detection position of the probe housing of the temperature sensor.

[0009] As a further solution of the present invention: The outside of the wire is heat-shrunk and protected with an internal heat-shrinkable tube, and the wire near the port of the probe housing is heat-shrunk with an external heat-shrinkable tube to prevent the wire from bending and breaking. After the heat-shrinkable tube shrinks by heating, it tightly wraps the wire to form a uniform insulating layer, effectively isolating the wire from the external environment and preventing the risk of electric leakage or short circuit.

[0010] As a further solution of the present invention: The core wire at the other end of the wire is crimped with a connector terminal. Before crimping the core wire, the oxide layer is removed and neutral vaseline is applied, or a copper-aluminum transition terminal is used.

[0011] As a further solution of the present invention: The temperature sensor is equipped with a high-temperature-resistant sealing ring on the probe housing, and is hermetically fixed in combination with the rice cooker lid and the housing fixing plate.

[0012] A method for detecting the temperature of a rice cooker is as follows: Step 1: When the rice cooker is working, the temperature inside the pot rises, and the probe housing of the temperature sensor senses the temperature inside the rice cooker pot. Step 2: The NTC thermistor detects the temperature inside the rice cooker pot sensed by the probe housing, and transmits the signal to the rice cooker ECU through the wire and the connector. Step 3: After receiving the feedback from the temperature sensor, the rice cooker ECU gives an instruction to the rice cooker thermostat through calculation. After receiving the instruction, the rice cooker thermostat adjusts the temperature inside the pot.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The temperature sensor is hermetically connected to the rice cooker lid. The probe of the temperature sensor extends into the pot. After being hermetically connected to the lid through the sealing ring, the temperature inside the pot does not leak out, ensuring that the temperature detected by the temperature sensor has a small error from the actual temperature inside the pot. The probe of the temperature sensor selects an NTC thermistor with high precision and is wrapped with a stainless steel probe housing with high heat transfer efficiency. An outer housing fixing plate is provided on the probe housing and fixed to the upper cover of the rice cooker to ensure the accurate position of the temperature sensor probe. The other end is connected to the rice cooker ECU through a wire harness connector, and the temperature detected by the temperature sensor probe is fed back to the ECU. The temperature inside the pot during the operation of the rice cooker is adjusted by the ECU command to the thermostat, which is convenient for accurately controlling the temperature inside the pot during the operation of the rice cooker, improving the softness of the rice and enhancing the taste of the rice; 2. By selecting an NTC thermistor with high temperature accuracy, the probe is wrapped with a stainless steel probe housing with high heat conduction efficiency. The space between the probe housing and the NTC thermistor is filled and fixed with an epoxy resin filling adhesive with high temperature resistance. A Teflon wire with high temperature resistance is selected to connect to the NTC thermistor. The wire is crimped to the connector terminal. A heat shrink tube is used to heat-shrink and fix the wire at the bending part of the probe housing and the wire to prevent the wire from breaking at the bend. BRIEF DESCRIPTION OF THE DRAWINGS

The positioning hole of the housing fixing plate 4-1 of the temperature sensor 10 is fixedly connected to the upper cover of the rice cooker, so that the probe housing 4 of the temperature sensor 10 is hermetically connected to the rice cooker lid 9 through the sealing ring 8 of the temperature sensor 10, ensuring that the temperature inside the rice cooker does not leak out. The connector 7 of the temperature sensor 10 is connected to the rice cooker ECU 11 to form a rice cooker temperature detection device.

[0019] In this embodiment: When the rice cooker is working, the temperature inside the pot rises. The probe housing 4 of the temperature sensor 10 senses the temperature inside the rice cooker pot and feeds back the change in the temperature inside the pot to the rice cooker ECU 11 through the connector 7 in the temperature sensor 10. After receiving the feedback from the temperature sensor 10, the rice cooker ECU 11 issues an instruction to the rice cooker thermostat through calculation. After receiving the instruction, the rice cooker thermostat adjusts the temperature inside the pot; It is hermetically connected to the pot lid through a temperature sensor 10. The probe of the temperature sensor 10 extends into the pot. After being hermetically connected to the pot lid through the sealing ring 8, the temperature inside the pot does not leak out, ensuring that the temperature detected by the temperature sensor 10 has a small error from the actual temperature inside the pot. The probe of the temperature sensor 10 selects an NTC thermistor 1 with high precision, and is wrapped with a stainless steel probe housing 4 with high heat transfer efficiency. An outer housing fixing plate 4-1 is arranged on the probe housing 4 and fixed to the upper lid of the rice cooker to ensure the accurate position of the probe of the temperature sensor 10. The other end is connected to the rice cooker ECU 11 through a wire harness connector 7, and the temperature detected by the probe of the temperature sensor 10 is fed back to the ECU. The temperature inside the pot during the operation of the rice cooker is adjusted by the ECU instructing the thermostat, which is convenient for accurately controlling the temperature inside the pot during the operation of the rice cooker, improving the softness of the rice, and enhancing the taste of the rice; For the temperature sensor 10 of this temperature detection device, an NTC thermistor 1 with high temperature accuracy is selected, and the probe is wrapped with a stainless steel probe housing 4 with high heat conduction efficiency.

The pin 1-1 of the NTC thermistor 1 is welded to the core wire 3-1 of the wire 3 by soldering or resistance welding; for soldering, the soldering iron head touches the pin 1-1 and the core wire 3-1 at the same time, quickly heats up to the melting of the solder, evenly fills the solder, avoids false soldering or accumulation, and keeps the solder joint stationary and cooling after removing the soldering iron to prevent cracks caused by vibration; for resistance welding, the electrode is used to apply pressure and generate Joule heat through the current to fuse the pin 1-1 and the core wire 3-1.

[0021] In this embodiment: during soldering, the surfaces of the pin 1-1 and the core wire 3-1 are cleaned with alcohol to ensure the cleanliness of the welding surface. A radiator clip is clamped at the root of the pin 1-1 (≥19 mm away from the NTC resin part) to reduce the heat conduction to the internal solder joint. A small amount of soldering paste is applied to the contact surface between the core wire 3-1 and the pin 1-1 to enhance the wettability; for resistance welding, the electrode is used to apply pressure and generate Joule heat through the current to fuse the pin 1-1 and the core wire 3-1, without the need for additional material assistance; it is convenient to fixedly connect the NTC thermistor 1 and the wire 3, and convenient to perform detection operations through the NTC thermistor 1.

[0027] In this embodiment: The heat shrinkable tube tightly wraps the wire 3 through high-temperature shrinkage to form a uniform insulating layer, effectively preventing electrical faults such as short circuits and electric leakage, and ensuring the safe operation of the circuit; after the heat shrinkable tube shrinks, it can completely seal the cable interface, preventing moisture, steam or chemical substances from invading, and avoiding line corrosion or aging caused by moisture; the wire 3 near the probe is vulnerable to external pulling, vibration or frequent bending. The heat shrinkable tube material has high toughness, which can enhance the mechanical strength of the cable connection, reduce the risk of fracture caused by repeated bending, and resist friction damage at the same time; using polymer materials such as polyolefin, it is resistant to chemical corrosion, ultraviolet rays and extreme temperatures, and extends the service life of the cable.
