Wireless temperature detection device for oven

Abstract

Disclosed is a wireless temperature detection device for an oven. The wireless temperature detection device is characterized by comprising a closed shell, and the small end is in a slender probe shape; an antenna is contained inside the large end of the shell; a wire is contained inside the small probe-shaped end of the shell, and one end of the wire is connected with the antenna; an acoustic surface wave temperature sensor is contained inside the end part of the small end of the shell, and the other end of the wire is connected with the acoustic surface wave temperature sensor. The wireless temperature detection device has the advantages that due to the fact that data transmission is achieved not through the wire connected with a circuit board, and the acoustic surface wave temperature sensor inside a probe of the shell is excited, so that temperature data are read from signals fed back by the acoustic surface wave temperature sensor, and no potential safety hazards exist even when the wireless temperature detection device is used at high temperature for a long time; the temperature inside food can be accurately detected and can be conveniently monitored, the heating degree of the food can be known in time, and a detection system is prevented from being disturbed by external temperature; the wireless temperature detection device is compact, small and exquisite in whole structure and convenient to hold and facilitates measurement, no special installation is needed, and using is easier and more flexible.

Description

technical field [0001] The invention relates to a sensor, in particular to a wireless temperature detection device for an oven. Background technique [0002] An oven is a closed electrical appliance used to bake food or dry products. The oven has been widely used in people's daily life as a kitchen equipment that replaces the traditional use of open flames to cook food. Household ovens are usually used for processing barbecue, grilling Western-style foods such as fish or pasta and pizza are more and more popular among people today because of their simple and convenient operation and relatively safe and healthy cooking methods. [0003] The process of food processing in the oven is mainly realized by heating the food in different ways. In the process of food heating, the degree of heating of the food (raw or cooked) has a very large relationship with its temperature. Sensing the temperature inside the food is the key to determine the heating of the food. A more intuitive met...

Problems solved by technology

However, the measurement method using thermal resistance (thermocouple) needs to connect the temperature measuring element and the temperature measuring system through metal wires before signal transmission. When the food is heated inside the oven, the metal wires are not easy to connect, and the outside of the wires The insulation layer is easy to age in high temperature environment, and prolonged use may cause the insulation layer to fall off, resulting in a decrease in the insulation level of the product, which poses certain safety hazards

In the prior art, there are other temperature measurement methods through optical fiber and infrared ray temperature measurement method. Because the optical fiber is easy to break, easy to break, and not resistant to high temperature, the accumulation of dust in the optical fiber temperature measurement method tends to reduce the insulation, and the wiring in the cabinet is more difficult. Large, high cost; the infrared temperature measurement method is greatly affected by the external heat of the food, and it is impossible to accurately know the temperature inside the food
