As people's quality of life continues to improve, they have higher demands on kitchen appliances, among which smart cooking equipment is one of the important representatives of emerging kitchen appliances. Existing smart cooking equipment mainly uses preset recipe programs to fix the material ratio and programmed heating gradient to achieve repetitive cooking of dishes. Smart cooking equipment cannot monitor the actual cooking status of dishes in real time, and then judge the degree of doneness of dishes.

To this end, some embodiments of the present invention provide a detection device 1000, as shown in Figures 1 to 4 of the accompanying drawings of the specification.

1 and 2, in the embodiment of the utility model, the detection device 1000 may include a collecting tube 100, a condensation assembly 200, a sampling tube 300, a sampling assembly 400 and a detector 500, wherein the collecting tube 100 may be directly connected to the interior of the cooking device 2000, so as to collect the volatile gas generated when cooking food in the cooking device 2000. It can be understood that the volatile gas tends to spread upward, so the collecting tube 100 may be arranged above the exhaust port of the cooking device 2000.

It should be noted that a lot of oil smoke and water vapor are often generated during cooking. On the one hand, these oil smoke and water vapor are very easy to pollute the detection device 1000, which is easy to cause the retention of volatile gas substances and interfere with the detection results; on the other hand, these oil smoke and water vapor will quickly condense after leaving the heat source, and there is a risk of damaging the detector 500. Based on this, referring to Figures 1 and 2, in the embodiment of the utility model, a condensation assembly 200 can be arranged above the collection tube 100. The condensation assembly 200 can include a condensation device 210 and a condenser 220, wherein one end of the condenser 220 is connected to the collection tube 100, and the other end is connected to the sampling tube 300, so that the gas in the collection tube 100 can pass through the condenser 220 to reach the sampling tube 300. The condensation device 210 can condense the water vapor and/or oil smoke in the inner cavity of the condenser 220. Specifically, the condensation device 210 can be a liquid circulation temperature controller, and its temperature control range can be 10-150°C. The liquid circulation temperature controller can use liquids such as water and silicone oil as a medium.

As shown in FIG. 1 and FIG. 2, in the embodiment of the utility model, one end of the sampling tube 300 is connected to the condenser 220, and the other end is connected to the external environment, thereby interfering with the discharge of excess gas. The side wall of the sampling tube 300 is provided with a sampling hole 310, and the sampling assembly 400 includes a sampling needle 410. The sampling needle 410 can be inserted into the sampling hole 310 to connect to the inner cavity of the sampling tube 300. The sampling needle 410 can directly extract the gas in the sampling tube 300. The detector 500 is connected to the sampling needle 410, and the detector 500 can detect the composition of the gas. Among them, the detector 500 can be a thermal conductivity detector 500 or a flame ionization detector 500. It should be noted that the thermal conductivity detector 500 can use the difference between the thermal conductivity of the sample molecule and the thermal conductivity of the carrier gas for detection, and the flame ionization detector 500 can use the current generated by the ionization of organic compounds in the flame for detection.

Since the sampling tube 300 needs to contain and buffer a sufficient amount of gas for the sampling needle 410 to effectively collect, based on this, in the embodiment of the utility model, the inner diameter of the sampling tube 300 is a, and a satisfies: a ≥ 5mm. In order to reduce the possibility of gas leakage from the gap between the sampling hole 310 and the sampling needle 410, in the embodiment, the diameter of the sampling hole 310 is b, and b satisfies: b ≥ 1mm.

The embodiment of the utility model provides a collecting tube 100 that can be connected to the cooking device 2000 to collect the gas of the food, and condenses the water vapor and/or oil smoke in the gas through the condensation component 200 to reduce the influence of the water vapor or oil smoke on subsequent detection, and provides a sampling needle 410 so that the sampling needle 410 passes through the sampling hole 310 and is connected to the inner cavity of the sampling tube 300, so as to extract the gas in the inner cavity of the sampling tube 300. The sampling needle 410 is connected to the detector 500 to realize the detection of the composition of the gas. By detecting the gas composition, the cooking degree of the food can be monitored in real time, which effectively enhances the precise control capability of the automatic cooking, enables the automatic cooking time to be accurately controlled, reduces energy consumption, saves the use cost, improves the cooking effect and quality of the automatic cooking, and provides users with a better use experience.

As shown in Fig. 1 and Fig. 2, in the embodiment of the utility model, the condenser 220 may include an outer tube 221 and an inner tube 222, wherein a cavity 2211 is formed inside the outer tube 221, the cavity 2211 is connected to the condensing device 210, and the inner tube 222 is located in the cavity 2211, one end of the inner tube 222 is connected to the collecting tube 100, and the other end is connected to the sampling tube 300. Specifically, the side wall of the condenser 220 may be provided with an upper opening and a lower opening, wherein the upper opening may be connected to the constant temperature medium recovery pipeline of the liquid circulation thermostat, and the lower opening may be connected to the output pipeline of the liquid circulation thermostat. The cavity 2211 is filled with a constant temperature liquid medium, which may be water vapor and/or oil smoke in the inner tube 222, and condensation occurs. The condensed water or oil smoke stops flowing to the upper sampling tube 300 under the action of gravity, thereby removing water vapor and/or oil smoke in the gas, reducing the possibility of water vapor or oil smoke damaging the detector 500, and greatly improving the accuracy of detection. In this embodiment, the inner tube 222 can be any one of a spiral tube, a straight tube and a spherical tube, thereby increasing the contact area between the inner tube 222 and the liquid medium in the cavity 2211, which not only improves the removal effect of water vapor and oil smoke, but also accelerates the condensation speed. The condenser 220 can be made of any one of alloy steel, stainless steel and glass, thereby improving the thermal conductivity of the condenser 220.

As shown in Fig. 1 and Fig. 3, in the embodiment of the utility model, the sampling assembly 400 may also include a sampling pump 420 and a connecting tube 430. One end of the sampling pump 420 is connected to the sampling needle 410, and the other end is connected to the connecting tube 430. The sampling pump 420 can extract the gas in the inner cavity of the sampling tube 300 through the sampling needle 410 to achieve full sampling. One end of the connecting tube 430 is connected to the sampling pump 420, and the other end is connected to the detector 500. The outside of the connecting tube 430 is wrapped with a constant temperature tube 440, and the constant temperature tube 440 can control the temperature of the connecting tube 430. The constant temperature tube 440 can be connected to a thermostat, and a constant temperature medium can also be stored in the constant temperature tube 440. The constant temperature medium can be water, gas, or oil, which is not limited in this embodiment. The outer surface of the constant temperature tube 440 can be wrapped with high temperature resistant heat insulating quartz wool or heat insulating plastic.

As shown in FIG. 1 and FIG. 2 , in an embodiment of the utility model, the detection device 1000 may further include an exhaust pump 600. The exhaust pump 600 may be disposed at the upper end of the sampling tube 300 and connected to the inner cavity of the sampling tube 300. The exhaust pump 600 is used to discharge the gas in the inner cavity of the sampling tube 300. Specifically, the exhaust pump 600 may include an air extraction pump and a gas transmission tube, wherein the gas transmission tube may be a bendable stainless steel gas pipeline with an inner diameter of not less than 1 mm. The exhaust pump 600 may not only timely update the gaseous substances in the sampling tube 300 and discharge the remaining large amount of volatile substances in time, but also maintain a constant pressure inside the detection device 1000.

In one example, the volatile gas generated by the cooking device 2000 may first enter the collecting tube 100, and then enter the inner tube 222 of the condenser 220 after passing through the collecting tube 100. The liquid circulation temperature controller continuously supplies a constant temperature medium to the cavity 2211 to condense and remove a large amount of water vapor and/or oil smoke entrained in the volatile gas. The treated gas enters the sampling tube 300, and the sampling pump 420 may extract part of the volatile gas from the inner cavity of the sampling tube 300 through the sampling needle 410. At the same time, the exhaust pump 600 will promptly discharge the remaining large amount of volatile gas to ensure that the gas substances in the sampling tube 300 are updated in time. The gas extracted by the sampling pump 420 is transmitted through the connecting tube 430 and then transported to the detector 500 for component analysis.

4 , an embodiment of the present invention further provides a cooking device 3000 , including a cooking device 2000 and the detection device 1000 of the above embodiment.

In the embodiment of the utility model, the cooking device 2000 can be an intelligent cooking machine, an intelligent soymilk maker, an intelligent microwave oven, etc. Since the cooking equipment 3000 adopts all the technical solutions of the detection device 1000 of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.
