具有冷却功能的温度传感器及应用其的燃气灶Temperature sensor with cooling function and gas cooker using it

技术领域technical field

本发明属于燃气灶技术领域，具体涉及一种具有冷却功能的度传感器及应用其的燃气灶。The invention belongs to the technical field of gas stoves, and in particular relates to a temperature sensor with a cooling function and a gas stove using the same.

背景技术Background technique

随着科技的发展，智能化产品不断出现在各个领域，智能化的实现离不开传感器对周围信息的收集，因此传感器收集数据的准确性也至关重要。With the development of science and technology, intelligent products continue to appear in various fields. The realization of intelligence is inseparable from the collection of surrounding information by sensors, so the accuracy of data collected by sensors is also crucial.

在燃气灶领域也相继推出了智能化产品，如带有防干烧功能的灶具、带有智能烹饪功能的灶具等，其原理为：传感器收集温度，并将温度信号反馈给控制系统，根据控制逻辑对灶具进行火力的关火或调节，达到防干烧或智能烹饪；因此，传感器对实际温度的准确判断十分重要。In the field of gas stoves, intelligent products have also been launched one after another, such as stoves with anti-dry function, stoves with intelligent cooking functions, etc. The principle is: the sensor collects the temperature and feeds back the temperature signal to the control system. The logic turns off or adjusts the firepower of the stove to prevent dry burning or intelligent cooking; therefore, it is very important for the sensor to accurately judge the actual temperature.

目前，市场上燃气灶测量锅底温度传感器分为两种，一种是接触式温度传感器，一种是非接触温度传感器。市面上主要采用接触式温度传感器，而接触式温度传感器的检测结果容易受燃气灶的火焰环境温度的影响，测量的精度较低。At present, there are two types of sensors for measuring the bottom temperature of gas stoves on the market, one is a contact temperature sensor, and the other is a non-contact temperature sensor. The contact temperature sensor is mainly used in the market, and the detection result of the contact temperature sensor is easily affected by the flame environment temperature of the gas stove, and the measurement accuracy is low.

具体实施方式Detailed ways

为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

实施例1Example 1

本发明实施例1提供一种具有冷风功能的温度传感器，如图1所示，其包括传感器组件1和风冷组件2，所述风冷组件2套设在传感器组件1外周用于通过冷风减少热量对传感器组件1的辐射；Embodiment 1 of the present invention provides a temperature sensor with cooling air function, as shown in Figure 1, which includes a sensor assembly 1 and an air cooling assembly 2, the air cooling assembly 2 is sleeved on the outer periphery of the sensor assembly 1 to reduce the radiation of heat to the sensor assembly 1;

这样，采用上述结构，在传感器组件1工作的同时，风冷组件2工作，通过产生的冷风降低传感器组件1周边的热量，减小了热量对传感器测温帽的辐射。In this way, with the above structure, while the sensor assembly 1 is working, the air-cooling assembly 2 is working, and the generated cold air reduces the heat around the sensor assembly 1, reducing the radiation of heat to the temperature measuring cap of the sensor.

所述风冷组件2包括第一风机、冷风通道21以及热风通道22，所述第一风机位于冷风通道21的入口处用于为冷风通道21提供冷风，所述热风通道22与冷风通道21的出口连接用于将热风排出；The air cooling assembly 2 includes a first fan, a cold air channel 21 and a hot air channel 22, the first fan is located at the entrance of the cold air channel 21 to provide cold air for the cold air channel 21, the hot air channel 22 and the cold air channel 21 The outlet connection is used to discharge the hot air;

这样，第一风机为冷风通道21提供冷风，冷风带走传感器周边的热量后通过热风通道22排出，实现了热量的排散。In this way, the first fan provides cold air for the cold air channel 21, and the cold air takes away the heat around the sensor and then discharges it through the hot air channel 22, thereby realizing heat dissipation.

所述冷风通道21和热风通道22均为隔热套管；所述隔热套管采用导热率较低的隔热材料，能够避免环境温度对传感器组件1的干扰，进一步提高测量的精度，从而提高温度传感器的可靠性。Both the cold air channel 21 and the hot air channel 22 are heat-insulating sleeves; the heat-insulating sleeve adopts a heat-insulating material with low thermal conductivity, which can avoid the interference of the ambient temperature on the sensor assembly 1, and further improve the accuracy of the measurement, thereby Improve the reliability of the temperature sensor.

实施例2Example 2

本发明实施例2提供一种具有冷却功能的温度传感器，如图2-3所示，其包括传感器组件1和风冷组件2，所述风冷组件2套设在传感器组件1外周用于通过冷风减少热量对传感器组件1的辐射；Embodiment 2 of the present invention provides a temperature sensor with cooling function, as shown in Fig. The cold wind reduces the radiation of heat to the sensor assembly 1;

这样，采用上述结构，在传感器组件1工作的同时，风冷组件2工作，通过产生的冷风降低传感器组件1周边的热量，减小了热量对传感器测温帽的辐射。In this way, with the above structure, while the sensor assembly 1 is working, the air-cooling assembly 2 is working, and the generated cold air reduces the heat around the sensor assembly 1, reducing the radiation of heat to the temperature measuring cap of the sensor.

所述风冷组件2包括第二风机、隔热管23以及排风孔24，所述第二风机位于隔热管23的入口处用为隔热管23提供冷风，所述排风孔24开设在隔热管23上用于将热风排出；The air-cooled assembly 2 includes a second blower fan, a heat insulating pipe 23 and an air exhaust hole 24, the second fan is located at the entrance of the heat insulating pipe 23 to provide cold air for the heat insulating pipe 23, and the air exhaust hole 24 is provided with On the heat insulation pipe 23, it is used to discharge the hot air;

这样，第二风机为隔热管23内提供冷风，冷风带走传感器周边的热量后通过排风孔24排出，实现了热量的排散。In this way, the second fan provides cold air for the heat insulation pipe 23, and the cold air takes away the heat around the sensor and then discharges it through the exhaust hole 24, thereby realizing heat dissipation.

进一步地，所述排风孔24设置有若干个且均匀布设在隔热管23上。Further, the exhaust holes 24 are provided in several and evenly distributed on the heat insulation pipe 23 .

进一步地，所述隔热管23设置有两层以上且相邻隔热管23上的排风孔24错位设置；Further, the heat insulation pipe 23 is provided with more than two layers and the exhaust holes 24 on the adjacent heat insulation pipe 23 are arranged in a misplaced position;

这样，相邻隔热管23上的排风孔24错位设置，避免了冷风还未带走热量时直接从对应的排风孔24排出；In this way, the exhaust holes 24 on the adjacent heat-insulating pipes 23 are misplaced, which prevents the cold air from being directly discharged from the corresponding exhaust holes 24 when the heat has not been taken away;

比如，设置两层隔热管23，靠近传感器组件1的为第一隔热管，与之相邻的为第二隔热管，第二风机为第一隔热管提供冷风，之后经过第一隔热管上的排风孔24排入第二隔热管，此时冷风温度稍微升高，仍可用于降低传感器组件1周边的温度，如果第一隔热管和第二隔热管上的排风孔24未错位设置，则冷风在通过第一隔热管上的排风孔24进入第二隔热管后未流动将直接从第二隔热管上的排风孔24排出，浪费了资源且没有实现相应的作用。For example, two layers of heat-insulated pipes 23 are set, the first heat-insulated pipe near the sensor assembly 1 is the second heat-insulated pipe adjacent to it, the second fan provides cold air for the first heat-insulated pipe, and then passes through the first heat-insulated pipe. The exhaust hole 24 on the heat insulation pipe is discharged into the second heat insulation pipe. At this time, the temperature of the cold air increases slightly, and it can still be used to reduce the temperature around the sensor assembly 1. If the first heat insulation pipe and the second heat insulation pipe If the exhaust hole 24 is not misplaced, the cold air will be discharged directly from the exhaust hole 24 on the second heat insulating pipe without flowing after entering the second heat insulating pipe through the exhaust hole 24 on the first heat insulating pipe, wasting resources and did not achieve the corresponding role.

另外，在实施例1和实施例2中，如图3所示，所述传感器组件1包括感温帽11、外壳12、支撑杆单元13以及接线端子14，所述支撑杆单元13的一端穿设于感温帽11内，另一端与接线端子14连接，所述外壳12的一端卡接在感温帽11上，另一端与支撑杆单元13固定连接；In addition, in Embodiment 1 and Embodiment 2, as shown in FIG. 3 , the sensor assembly 1 includes a temperature sensing cap 11, a housing 12, a support rod unit 13 and a connection terminal 14, and one end of the support rod unit 13 passes through Set in the temperature sensing cap 11, the other end is connected to the terminal 14, one end of the housing 12 is clamped on the temperature sensing cap 11, and the other end is fixedly connected to the support rod unit 13;

所述支撑杆单元13包括弹簧131、支撑杆132以及导向杆133，所述弹簧131套设在导向杆133的一端且位于外壳12内，所述支撑杆132设置在导向杆133外周且其上端于弹簧131抵接；The support rod unit 13 includes a spring 131, a support rod 132 and a guide rod 133. The spring 131 is sleeved on one end of the guide rod 133 and is located in the housing 12. The support rod 132 is arranged on the outer circumference of the guide rod 133 and its upper end abut against the spring 131;

燃气灶放置锅体时，锅体与感温帽11接触，当感温帽11受到锅底向下的压力时，弹簧131压缩，带动支撑杆132和导向杆133向下移动，当取走锅体后，感温帽11上的压力消失，弹簧131复位。When the gas cooker is placed on the pot body, the pot body is in contact with the temperature sensing cap 11. When the temperature sensing cap 11 is under the downward pressure of the bottom of the pot, the spring 131 is compressed, driving the support rod 132 and the guide rod 133 to move downward. After body, the pressure on the temperature sensing cap 11 disappears, and the spring 131 resets.
