Embodiment 1

[0060] Such as image 3 As shown, a refrigeration device includes a refrigeration device body and an odor detection device 201 as described in the above embodiments, and also includes an actuator 202 , an air extraction device 203 , and a gas sensor 204 .

[0061] Such as Figure 4 As shown, the air extraction device 203 includes a plurality of airflow passages 203a and an air suction pump 203b, and one end of the plurality of airflow passages 203a is respectively connected to multiple areas such as area 1, area 2, area 3 ... area n in the refrigeration equipment, and the plurality of The other end of the airflow channel 203a is connected to the air pump 203b, and the air pump 203b extracts the gas in the corresponding area through the multiple airflow channels 203a and sends it to the gas sensor 204.

[0062] The gas sensor 204 is used to measure the odor spectrum of a specific odor in the refrigeration equipment.

[0063] The specific smell described in this embodiment is ...

Embodiment 2

[0067] Such as Figure 5 As shown, the refrigeration equipment provided in this embodiment includes an odor detection device 301, and also includes an air extraction device 302, and a gas sensor 303. One is the same, the difference is:

[0068] The refrigeration equipment provided in this embodiment also includes a display unit 304. Optionally, the display unit 304 includes a plurality of light-emitting diodes 304a corresponding to each area in the refrigerator, and is used to determine the occurrence of food in the corresponding area according to the control signal sent by the odor detection device 301. Luminous display when deterioration occurs.

[0069] The display unit 304 in the embodiment of the present invention is not limited to light-emitting display, and may also be a text display or other display methods.

[0070] In addition, the refrigeration equipment provided in this embodiment further includes an alarm device 305 corresponding to each area, configured to outp...

Abstract

The invention provides a refrigeration equipment smell detection method, a detection device and refrigeration equipment. According to the method, an air extraction control device extracts gas in each area according to a preset sequential control; a concentration measuring module measures the smell spectrum of a specific smell in the gas in each area and compares the smell spectrum with a smell model; and a smell determination model calculates the concentration of the specific smell according to the comparison results, determines whether the food deteriorates or not according to the concentration of the specific smell, generates a corresponding control signal and sends the signal to an execution device. Food deterioration in the areas can be detected timely, and the sensitivity and reliability are high.

Description

technical field [0001] The invention relates to gas sensing technology, in particular to a refrigeration equipment odor detection method, detection device and refrigeration equipment. Background technique [0002] Refrigerators, freezers and other refrigeration equipment are common household appliances in people's daily life. People often buy a large amount of vegetables, fruits and meat at one time and store them in refrigeration equipment. However, refrigeration equipment is only a tool to delay food deterioration, and cannot To prevent food from deteriorating, some existing refrigeration equipment is equipped with gas sensors, but the background odor in the refrigeration equipment is complicated. When a small part of food deteriorates in some areas, the gas sensor cannot be sensed in time, and the sensitivity is low and the reliability is not good. high. Contents of the invention [0003] Aiming at the problem of low sensitivity and reliability of the gas sensor instal...
