Embodiment 1

[0040] Such as Figure 1-2 As shown, the present invention is a kind of peculiar smell detection box, comprises detection box main body 1, and detection box main body 1 forms closed circulation passage through peculiar smell detection room 3, clean room 4, first pipeline 5, second pipeline 6, is installed in Under the action of the fan 12 in the clean room 4, the internal gas is circulated;

[0041] Among them, electric valves 7 are installed on the first pipeline 5 and the second pipeline 6; the odor detection chamber 3 is used to detect the working efficiency of the odor removal device, and the clean room 4 is used to purify the residual odor in the odor detection chamber 3;

[0042] The odor detection chamber 3 is provided with a spoiler fan 8, a heater 9, an odor sensor 10, and an installation platform 11 for a module to be detected;

[0043] A purification device 13 is installed in the clean room 4 .

[0044] Wherein, the controller 2 installed on the main body 1 of the...

Embodiment 2

[0056] Such as image 3 Shown, a kind of peculiar smell detection box control method of the present invention, the steps are as follows:

[0057] Step 1: After the power is turned on, the electric valve 7 is closed, and the odor source is manually injected into the box. If the surface of the heater 9 is in a liquid state, the heater is manually turned on. If the sample is in a gaseous state, the heater is kept closed, and the controller 2 automatically memorizes Sample time;

[0058]Step 2, immediately after the sample injection, the spoiler fan 8 and the odor sensor 10 are manually turned on by the controller 2. After 3 minutes of sample injection, the system automatically records the odor concentration a detected by the odor sensor 10, and turns on the odor removal device;

[0059] Step 3, the odor sensor 10 and the spoiler fan 8 are kept on, and after 2 hours, the system automatically records the detection concentration b of the gas sensor;

[0060] Step 4, after 2 hours ...

Abstract

The invention discloses an odor detection box and a control method, and relates to the technical field of odor detection boxes. The odor detection box comprises a detection box main body, wherein thedetection box main body forms a closed circulation channel through an odor detection chamber, a purification chamber, a first pipeline and a second pipeline; under the effect of a fan installed in thepurification chamber, an internal gas is circulated; a flow disturbing fan, a heater, an odor sensor and a to-be-detected module installation table are arranged in the odor detection chamber; and a purification device is installed in the purification chamber. According to the odor detection box and control method, the environment in a refrigerator is simulated to carry out odor detection, meanwhile, a purification system is installed in a matched mode, odor is quickly removed, the odor in a room is detected, and the odor detection experiment efficiency is improved; and in addition, the heateris installed, so that the removal efficiency of the odor generated by liquid or solid is conveniently detected.

Description

technical field [0001] The invention belongs to the technical field of odor detection boxes, in particular to an odor detection box and a control method. Background technique [0002] With the improvement of living standards and the pursuit of high-quality life. High-end air-cooled refrigerators have gradually entered thousands of households. While meeting consumer needs with functions such as larger capacity and less frosting, the problem of odors between ingredients has become increasingly prominent. [0003] At present, different deodorization methods have been researched and applied in refrigerators. Most of the verification methods are to install deodorization modules in the refrigerator compartment, punch holes in the door or side of the refrigerator, and inject odor gas into the refrigerator. The air circulation or external fan diffuses the odor, and regularly measures the odor content in the refrigerator to judge the odor removal performance of the module. However,...
