It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The principles and structures of the present invention are described in detail below with reference to the drawings and the examples.
Within the refrigerator industry, deodorizing is mainly performed by installing deodorizing devices (e.g., ion deodorizing and sterilizing devices) inside the refrigerator. The existing electronic odor removal device is mainly controlled by the following method: when the odor appears, the odor removing device is started manually through the odor removing function menu; or periodically starting the odor removing device at regular time in the working process of the refrigerator; and an odor sensor is arranged in the refrigerator, and when the odor concentration value in the refrigerator reaches a set value, the odor purifying device is started. However, the above methods have the problem of low odor removal efficiency, and require direct control by the user, or the odor removal effect cannot be adjusted according to the actual situation. The invention proposes innovation based on the sterilization, smell-removing and fresh-keeping technology of the air-cooled refrigerator, and the change values of the temperature, the humidity and the oxygen concentration of the refrigerating chamber are collected through the chamber temperature and humidity sensor and the oxygen concentration detector, so that a plurality of smell devices with different smell-removing effects start to work in sequence, the smell-removing effect duration is reasonably improved, meanwhile, the characteristics of low-temperature environment and refrigeration and air-drying are fully utilized to reduce the activity of food microorganisms or bacteria, and the carbon emission generated by aerobic respiration of vegetables and fruits or the damage of chamber smell by ethanol fermentation is further inhibited. And setting the highest threshold value and the lowest threshold value according to the comparison of the measured humidity value and the measured oxygen concentration value, accurately judging the working time of each odor removing device, and comprehensively improving the odor removing and fresh keeping effects of the room.
As shown in fig. 1, the present invention provides a method for controlling odor removal of a refrigerator, wherein a refrigerating compartment of the refrigerator is provided with a plurality of odor removal devices with different odor removal effects, a temperature and humidity sensor and an oxygen concentration detector for detecting oxygen concentration (the oxygen concentration detector can be a part of the odor removal devices); the control method specifically comprises the following steps:
step 1, monitoring operation information of a refrigerator and temperature parameters, humidity parameters and oxygen concentration parameters of a refrigerator compartment, namely acquiring real-time temperature parameters, humidity parameters and oxygen concentration parameters of the refrigerator compartment, so as to facilitate subsequent control logic;
and 2, controlling the working states and working time lengths of a plurality of odor purifying devices with different odor purifying effects in the refrigerator compartment according to the running information, temperature parameters, humidity parameters and numerical changes of oxygen concentration parameters of the refrigerator, and matching the current states in the refrigerator compartment to maximize the odor purifying efficiency.
The operation information of the refrigerator specifically includes: the switch of the odor removing device is controlled by adding the running information of the refrigerator, the whole temperature and humidity, gas components and concentration of the compartment are optimized to achieve balance under the influence of the condition that the refrigerator is not opened or closed after running for a long time in the refrigerating chamber of the refrigerator, and the odor removing and fresh-keeping effects of the gas are improved.
The step 2 of controlling the working states and the working time lengths of the odor purifying devices with different odor purifying effects in the refrigerator compartment according to the running information, the temperature parameter, the humidity parameter and the numerical variation of the oxygen concentration parameter of the refrigerator specifically comprises the following steps:
step 21, judging whether the power-on duration of the refrigerator is greater than or equal to a preset power-on duration, wherein the preset power-on duration can be specifically set to 24 hours or other values according to actual conditions or seasons;
if yes, step 211, the oxygen concentration detector is opened to detect the oxygen concentration parameter of the refrigerator compartment, and the working states and the working time lengths of the odor purifying devices are controlled in a preset range where the current value of the oxygen concentration parameter is subtracted according to the current value of the humidity parameter of the refrigerator compartment;
if not, step 212, determining whether to open the oxygen concentration detector according to the temperature parameter of the refrigerator compartment and the door opening and closing action parameter; if the oxygen concentration detector is opened, the working states and the working time lengths of the odor purifying devices are controlled according to a second preset range where the current value of the humidity parameter of the refrigerator compartment is subtracted from the current value of the oxygen concentration parameter, if the oxygen concentration detector does not have opening actions, at least one odor purifying device with relatively low odor purifying effect is directly controlled to be in a working state, the rest odor purifying devices are controlled to be in a non-working state, and the step of monitoring the running information of the refrigerator is returned.
Different control logics are executed by distinguishing the electrifying duration of the refrigerator, so that the technical means of sterilization and odor removal can be met, the control of temperature, humidity and oxygen concentration under the condition of refrigeration and no refrigeration can be optimized, the food microorganisms or bacteria are weakened to a certain extent, the food primordial ecology is destroyed by excessive propagation under the condition of oxygen and sufficient moisture, the air-drying storage of the food is facilitated by controlling the humidity, the carbon emission of fresh vegetables or fruits caused by aerobic respiration can be effectively avoided by controlling the oxygen concentration, and the odor of a compartment is further inhibited by fermenting and destroying sulfide, carbide or alcohol compounds. The temperature and humidity value and the oxygen concentration value are timely detected according to the refrigerator operation time and the refrigeration mode, so that the secondary odor removing device B meets the relation between the two working time, in addition, the door opening and closing actions generated after a period of actual use by a user are considered, and the original ecological odor removing and fresh-keeping effects are affected to a certain extent if the compartment is contacted with the external environment and is newly put into storage food during the period.
Step 211, controlling the working states and the working durations of the odor removing devices according to the preset range where the current humidity parameter minus the current oxygen concentration parameter of the refrigerator compartment is located, specifically includes the steps of:
setting a lower limit threshold a and an upper limit threshold b of oxygen concentration, a lower limit threshold C and an upper limit threshold d of humidity, and setting an R phase as a difference value between a current humidity parameter H1 and a current oxygen concentration parameter C1, namely, applying a humidity and oxygen concentration difference calculation method (it should be noted that the steps of setting the threshold and the R phase can be preset in advance before the step 1, and are written in the place only for facilitating understanding of the scheme, and in other embodiments, the steps of setting the threshold and the R phase can be set before the step 1 or between the steps 1 to 2);
judging R Phase (C) C-b is not more than or equal to;
if yes, controlling at least one deodorizing device with relatively low deodorizing effect to be in an operating state, and controlling the rest deodorizing devices to be not operated, otherwise, judging that c-b is less than R Phase (C) Whether < d-a holds;
if it is true that the method is not successful,controlling the operation t of at least one deodorizing device with relatively high deodorizing effect 1 Time t 1 ＝[(H 1 -C 1 )/(c-b)]X 0.5, controlling the rest of the odor removing devices to be not operated;
if not, judge R Phase (C) Whether d-a is equal to or not; if yes, controlling at least one odor removing device with relatively high odor removing effect to work t 2 Time t 2 ＝[(H 1 -C 1 )/(d-a)]X 1, controlling the rest odor removing devices to be not operated; if not, returning to the step of setting the upper limit threshold of the oxygen concentration.
Where R is Phase (C) As a judging standard, the C1 value can tend to be constant under the stable running state of the compartment, and the peculiar smell can be directly caused to flow and spread by the heat load and the water evaporation of food, so the relative humidity content value H1 can be selected within 40-70 percent and is obviously higher than the C1 value, and the surface of the food material is easily mixed with smell due to the influence of air drying in the process of refrigerating air circulation, so the smell removing devices with different smell removing effects are separated to perform smell removing work, the working time of each smell removing device can be accurately judged, and the smell removing and fresh-keeping effects of the compartment are comprehensively improved.
In the step 212, determining whether to open the oxygen concentration detector according to the temperature parameter of the refrigerator compartment and the door opening and closing operation parameter includes the steps of:
judging whether the current temperature parameter of the refrigerator compartment is within a preset temperature range;
if so, stopping refrigerating the refrigerator compartment, and opening an oxygen concentration detector to detect the oxygen concentration parameter of the refrigerator compartment;
if not, judging whether the difference value between the current gear temperature parameter T2 of the refrigerator compartment and the current temperature parameter of the refrigerator compartment is larger than or equal to a preset temperature difference value or not;
if not, stopping refrigerating the refrigerator compartment, and opening an oxygen concentration detector to detect an oxygen concentration parameter of the refrigerator compartment;
if so, judging whether door opening and closing actions exist in a preset time length (the preset time length can be specifically 24 hours or can be set to other time according to the needs) according to door opening and closing action parameters of the refrigerator compartment; if the door is opened or closed, the oxygen concentration detector does not open; if the door opening and closing action is not performed, the oxygen concentration detector is opened to detect the oxygen concentration parameter of the refrigerator compartment.
The steps actually consider the door opening and closing actions generated after a period of time of actual use of a user, and if the compartment is contacted with the external environment during the period and the original ecological smell removing and fresh-keeping effects are affected to a certain extent when the compartment is newly put into storage, so that the oxygen concentration detector does not have the opening actions when the door opening and closing actions are carried out, and a smell removing device with a lower smell removing effect is directly opened to remove the smell.
In the step 212, the step of controlling the working states and the working durations of the plurality of odor removing devices according to the second preset range where the current value of the humidity parameter minus the current value of the oxygen concentration parameter of the refrigerator compartment is located includes the steps of:
setting a lower limit threshold a and an upper limit threshold b of oxygen concentration, a lower limit threshold c and an upper limit threshold d of humidity, and setting R '' Phase (C) For the current humidity parameter H 2 With the current oxygen concentration parameter C 2 It should be noted that the step of setting the threshold and the R-phase may be specifically preset before the step 1, and the step of setting the threshold and the R-phase may be written here only for the sake of understanding the scheme, and in other embodiments, the step of setting the threshold and the R-phase may be performed before the step 1 or between the steps 1 and 2;
judging R' Phase (C) D-a is not more than or equal to;
if yes, controlling at least one odor removing device with relatively high odor removing effect to work t 3 Time t 3 ＝[(H 2 -C 2 )/(c-b)]X 0.5; controlling the rest of the odor removing devices to be in a non-working state;
if not, judging that c-b is less than R' Phase (C) Whether < d-a holds; if so, controlling at least one deodorizing device with relatively high deodorizing effect to work for t4 time, t 4 ＝[(H 2 -C 2 )/(d-a)]X 1, controlling the primary deodorizing device to be in a non-working state; if not, controlling the refrigerator compartment to operate according to normal control logic.
R′ Phase (C) The actual power-on time of the refrigerator is matched, when the actual power-on time is short, the humidity in the refrigerator is high, and the odor purifying device with relatively high odor purifying effect is opened, so that carbon emission generated by aerobic respiration of vegetables and fruits or odor in a compartment can be prevented from being damaged by ethanol fermentation.
In a specific embodiment, the plurality of odor removing devices are specifically two odor removing devices, which respectively include: the primary deodorizing device a and the secondary deodorizing device B (it should be noted that, in the partial block diagram in the drawing, the corresponding deodorizing device is directly represented by A, B), and the deodorizing effect of the secondary deodorizing device is higher than that of the primary deodorizing device, which may be specifically a deodorizing module in the existing refrigerator, and the present invention is not limited specifically, and any two deodorizing devices having different deodorizing effects are within the scope of the present invention.
As shown in fig. 2, the following details of the control logic flow will specifically use the primary deodorizing device a and the secondary deodorizing device B as specific embodiments;
