The household disinfection cabinet is usually arranged in a kitchen to sterilize and disinfect kitchen ware, but a large amount of oil smoke exists in the air in the kitchen, vegetables are rotten, various smells such as mildewing in the cabinet exist, the air pollution of the kitchen is serious, the personal injury is huge, the purification of the air in the kitchen is also important, the disinfection cabinet in the prior art needs to artificially adjust the working mode of the disinfection cabinet to purify the environment of the kitchen, and the working state of the disinfection cabinet cannot be automatically controlled according to the scene of the kitchen. The application is described with reference to a kitchen as a use place of the sterilizing cabinet, but the sterilizing cabinet of the application is not limited to be applied in the kitchen.
The application provides a control method of a disinfection cabinet, as shown in figure 1, comprising the following steps:
s100: the infrared sensor 150 detects a heat radiation signal within a preset distance range;
s200, controlling the starting of the purification assembly 120 to purify the external air according to the detected heat radiation signal;
s300, when the infrared sensor 150 does not detect the heat radiation signal, the first odor sensor 160 is started to detect the first odor signal in the disinfection cabinet 100;
s400, starting the purification assembly 120 to purify the interior of the disinfection cabinet 100 according to the first smell signal of the first smell sensor 160;
s500, when the infrared sensor 150 does not detect the heat radiation signal and the first odor sensor 160 does not detect the first odor signal in the sterilizer 100, starting the second odor sensor 170 to detect the second odor signal within the preset distance range;
s600, the purifying module 120 starts the external air purifying process according to the second odor signal of the second odor sensor 170.
The infrared sensor 150 is composed of a fresnel lens, a pyroelectric sensor and an induction signal processing circuit, and the pyroelectric sensor is provided with an infrared filter in front of the pyroelectric sensor, so that an infrared radiation signal with the wavelength of 10 μm emitted by a human body can be detected, and as long as a user walks in a monitoring area of the pyroelectric sensor, the sensor outputs a corresponding electric signal, and the signal is processed by the induction signal processing circuit and then outputs a control signal to control the load, so that the detection and analysis of the user are realized.
The odor sensor in the application is a VOC (volatile organic compounds, volatile organic compound) odor sensor, the VOC odor sensor is composed of a gas-sensitive metal oxide, electrodes and a heating film, the gas-sensitive metal oxide comprises high-porosity and granular semiconductor materials, the particles form resistance between the electrodes through unique conductive paths, when the VOC is contacted with the sensor, the VOC interacts with the gas-sensitive metal oxide, and a series of chemical reactions are generated by the heating film in a driving way, so that the predictably adjusted measuring resistance is brought. The VOC sensor itself can detect a variety of VOCs and provide a relative output corresponding to changes in VOC concentration, for example ozone, soot, and mildew present in the kitchen all belong to VOCs, which can cause changes in the resistance of the gas sensitive metal oxide.
When the infrared sensor 150 detects a heat radiation signal within a preset distance range, that is, when a user is in the kitchen, it is determined that the current kitchen is in a use state, more volatile organic compounds harmful to human health are generated, and the purification assembly 120 is started to purify the air in the kitchen in the use state. When the infrared sensor 150 does not detect the heat radiation signal, that is, the user is not in the kitchen, the first odor sensor 160 is activated to detect the first odor signal in the sterilizing cabinet 100, and when the first odor signal is detected, it is indicated that volatile organic compounds harmful to human health exist in the sterilizing cabinet 100, and the air purifying process in the sterilizing cabinet 100 is activated by the purifying module 120. When the kitchen is in an unused state and the inside of the sterilizer 100 does not need to be cleaned and sterilized, the second odor sensor 170 detects a second odor signal of the kitchen environment, and when the second odor sensor 170 detects the second odor signal of the kitchen environment, that is, volatile organic compounds harmful to human health exist in the kitchen environment, the cleaning assembly 120 is started to clean the air in the kitchen in the unused state. The control method of the disinfection cabinet provided by the application can control the operation of the purification assembly 120 according to the scene of the kitchen and the disinfection cabinet 100.
Optionally, the disinfection cabinet 100 further includes a clock module, where a working period and a sleep period other than the working period are preset in the clock module; as shown in fig. 2, when the infrared sensor 150 does not detect the heat radiation signal and the first odor sensor 160 does not detect the first odor signal within the sterilizing cabinet 100, starting the second odor sensor 170 to detect the second odor signal within the preset distance range includes:
s510, when the infrared sensor 150 does not detect the heat radiation signal and the first odor sensor 160 does not detect the first odor signal in the disinfection cabinet 100, acquiring the current moment recorded by the clock module;
and S520, if the current moment is in the working period, starting the second odor sensor 170 to detect a second odor signal in a preset distance range.
The household disinfection cabinet 100 is usually arranged in a kitchen, the cooking time of the kitchen is usually in daytime and night, and few users use the kitchen, so that the working period and the dormant period of the disinfection cabinet 100 can be set, when the kitchen is not in use and the disinfection and purification are not needed in the disinfection cabinet 100, whether the current moment is in the working period or not is judged first, if the current moment is in the working period, the second odor sensor 170 is used for detecting whether the environment in the kitchen needs to be purified, and if the second odor sensor 170 is used for detecting the second odor signal, the environment in the kitchen needs to be purified, and the purification assembly 120 is started for purifying the air in the kitchen in the unused state. If in the sleep period, the sterilizer 100 is turned off. The clock module is arranged, and the working period and the dormancy period are preset, so that the disinfection cabinet 100 can be reasonably utilized to purify the interior of the disinfection cabinet 100 and the kitchen environment.
It should be noted that, the specific setting of the working period and the sleep period is not limited in particular, and may be specifically set according to actual situations, and the working period may be set in a range of 6:00-22:00, and the time other than the working period is the sleep period.
In one implementation manner of the embodiment of the present application, as shown in fig. 3, after the infrared sensor 150 detects the heat radiation signal within the preset distance range, the control method of the disinfection cabinet further includes:
s110, when a heat radiation signal is detected, starting a clock module to start first timing;
s120, detecting a heat radiation signal within a preset distance range by the infrared sensor 150 within a first preset duration;
s130, when the first timing reaches a first preset duration, the heat radiation signal is kept, and the starting of the purification assembly 120 for purifying the external air is controlled;
s131, stopping the clock module first timing when the infrared sensor 150 does not detect the heat radiation signal.
The heat radiation signal continuously exists in the first continuous period, that is, the user continuously waits in the kitchen for the first continuous period, so that the user is judged to cook in the kitchen, and the kitchen is in a use state at the moment, more VOC can be generated, and the purifying component 120 is required to purify the kitchen air in the use state.
Because sometimes the user may get something to the kitchen or something else instead of cooking, but the getting something does not generate VOC, determining whether the user is continuously in the kitchen for the first preset duration avoids misjudgment caused by the user coming in and out of the kitchen for a short time, and thus the purification assembly 120 is turned on under unnecessary conditions.
The duration of the first preset duration is not particularly limited, and may be set according to circumstances, and may be set to 60S, for example, because taking things or something else leaves the kitchen within 60S.
Optionally, as shown in fig. 4, after stopping the first timing of the clock module, the method of the disinfection cabinet 100 further includes:
s132, starting a clock module to start second timing;
s133, detecting a heat radiation signal within a preset distance range through the infrared sensor 150 within a second preset duration;
s134, when the second timing reaches a second preset duration, the heat radiation signal is detected, and the first timing of the clock module continues to time;
s135, stopping the first timing and the second timing of the clock module and returning to zero when the second timing reaches the second preset duration and the heat radiation signal is not detected.
Sometimes, the user cooks, leaves the kitchen for a short time after entering the kitchen, when the user enters the kitchen again, the first timer needs to count again, in order to avoid misjudgment of the disinfection cabinet caused by the short-time leaving of the user, after the user leaves the kitchen, the second timer starts, if the user returns to the kitchen again within a second preset duration, the first timer continues the previous timer, so as to judge whether the user enters the kitchen for cooking, if the user does not return to the kitchen within the second preset duration, the user is judged to have left, and the first timer and the second timer stop counting and return to zero. The second timing can avoid misjudgment of the disinfection cabinet caused by short-time departure after the user enters the kitchen. The second preset duration is not particularly limited as long as the first preset duration is the same, and may be set to 30S by way of example.
