All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The conventional refrigerator deodorizer is started to generate and release a smell removing substance, such as ozone, at regular time, enters a standby state after being released for a period of time, and circulates until the battery power is exhausted, however, the operation mode is mechanical and single, only starting and closing can be carried out, ozone is generated when the concentration of ozone is high, and the operation power of the deodorizer is difficult to control according to the actual concentration of ozone in the refrigerator.
Based on the technical scheme, the working power of the deodorizer is controlled according to the actual concentration of the odor removing substances by collecting the actual concentration of the odor removing substances, so that the energy consumption of the deodorizer is reduced, and the service life of the deodorizer is prolonged.
In accordance with an embodiment of the present invention, there is provided an embodiment of a method of controlling a deodorizer, wherein the steps illustrated in the flow chart of the drawings may be performed in a computer system, such as a set of computer-executable instructions, and wherein, although a logical order is illustrated in the flow chart, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
In this embodiment, a method for controlling a deodorizer is provided, which can be used for a deodorizer, such as a deodorizer disposed in a refrigerator, etc., fig. 1 is a flowchart of a method for controlling a deodorizer according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
s11, obtaining the concentration of the odor elimination substance in the current space.
The odor removing substance can change the generated odor substances into odor-free substances by oxidation, reductive decomposition, neutralization reaction, addition reaction, condensation reaction, ion exchange reaction, etc. Taking ozone as an example, because ozone has strong oxidizing property, ozone can generate chemical reaction with chemical substances emitting peculiar smell in the current space, and the chemical substances are oxidized and decomposed into nontoxic and odorless substances, so that the effect of removing peculiar smell is achieved.
The concentration of odor elimination substance in the air is now the concentration of odor elimination substance in the space in which the odor eliminator is located. The odor removing substance concentration can be obtained through a concentration detection sensor arranged in the odor remover, and the concentration detection sensor can feed back the odor removing substance concentration detected by the concentration detection sensor to the odor remover controller, so that the odor remover can obtain the odor removing substance concentration in the current space in real time.
S12, judging whether the concentration of the odor removing substance is less than the first preset concentration value.
The first preset concentration value is the minimum concentration of odour-combating substance confined in the current space. The odor remover obtains the concentration of the odor removing substances in the current space in real time, compares the concentration of the odor removing substances with a first preset concentration value, and determines whether the concentration of the odor removing substances is smaller than the first preset concentration value. When the concentration of the odor elimination substance is less than the first preset concentration value, step S13 is executed, otherwise, other operations are executed. Wherein the other operation may be to maintain a current operating state, such as to maintain a standby state or to continue to release odour-combating substances at a current power; it is also possible to return to continue to detect the concentration of odour-combating substance in the current space, and other operations are not limited herein.
S13, obtaining the change state of the concentration of the odor removing substance.
The state of change of the concentration of the odor elimination substance is used for representing the trend of the change of the concentration of the odor elimination substance in the current space, namely, the change of the concentration of the odor elimination substance shows an upward trend or a downward trend. When the concentration of the odor elimination substance is less than the first preset concentration value, it indicates that the concentration of the odor elimination substance in the current space is insufficient to achieve the odor elimination effect. At this time, the deodorizer can acquire the variation trend of the concentration of the odor eliminating substance in the current space to determine the variation state of the concentration of the odor eliminating substance in the current space.
And S14, adjusting the working power of the odor eliminating device based on the change state of the concentration of the odor eliminating substance.
And the deodorizer controls the working power of the deodorizer for releasing the odor removing substances according to the acquired change state of the concentration of the odor removing substances. Specifically, when the deodorizer determines that the change trend of the concentration of the odor removing substance in the current space shows an ascending trend, the deodorizer can adjust the working power of the deodorizer according to the ascending change quantity of the concentration of the odor removing substance; when the deodorizer determines that the change trend of the concentration of the odor removing substances in the current space presents a descending trend, the deodorizer can adjust the working power of the deodorizer according to the descending change quantity of the concentration of the odor removing substances.
According to the control method of the odor removing device provided by the embodiment, by obtaining the concentration of the odor removing substance in the current space, if the concentration of the odor removing substance in the current space is smaller than a first preset concentration value, the change state of the concentration of the odor removing substance is obtained, and the working power of the odor removing device is adjusted. The method realizes the control of the working power of the deodorizer according to the concentration of the odor removing substance in the current space, reduces the energy consumption of the deodorizer, prolongs the service life of the deodorizer, simultaneously can ensure that the concentration of the odor removing substance is in a reasonable range, and avoids the excessive release of the odor removing substance.
In this embodiment, a control method of a deodorizer is provided, which can be used for a deodorizer, such as a deodorizer disposed in a refrigerator, etc., fig. 2 is a flowchart of the control method of the deodorizer according to the embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
s21, obtaining the concentration of the odor elimination substance in the current space. For a detailed description, refer to the related description of step S11 corresponding to the above embodiment, and the detailed description is omitted here.
S22, judging whether the concentration of the odor removing substance is less than the first preset concentration value. For a detailed description, refer to the related description of step S12 corresponding to the above embodiment, and the detailed description is omitted here.
S23, when the concentration of the odor elimination substance is less than the first preset concentration value, acquiring the change state of the concentration of the odor elimination substance. For a detailed description, refer to the related description of step S13 corresponding to the above embodiment, and the detailed description is omitted here.
And S24, adjusting the working power of the odor eliminating device based on the change state of the concentration of the odor eliminating substance.
Specifically, the step S24 may include:
s241, acquiring a concentration change range corresponding to the change state, and determining a first target power corresponding to the concentration change range.
The concentration variation range is the variation range of the concentration of the odor removing substance collected at adjacent sampling intervals, for example, the concentration variation range is expressed by Δ S, and assuming that the concentrations of the odor removing substance collected at adjacent sampling intervals are S1 and S2, respectively, the variation value of the concentration of the odor removing substance is | S2-S1| and when | S2-S1| is (0, 10 mg/m) |3) When it is (0, 10 mg/m)3) Is the concentration variation range corresponding to the current variation state. The first target power is the odor elimination substance release power corresponding to the range of concentration variation. The deodorizer can be matched with different odor removing substance release power according to different concentration variation ranges.
Alternatively, the first target power may include a first power and a second power, and the concentration variation range may include a first preset variation range and a second preset variation range, the first preset variation range and the second preset variation range being divisions of the concentration variation range, that is, the concentration variation range (0, S) into a first preset variation range (0, Si) and a second preset variation range [ Si, S), the first power being a smell elimination site release power corresponding to the first preset variation range (0, Si), and the second power being a smell elimination site release power corresponding to the second preset variation range [ Si, S).
Specifically, when the first target power may include a first power and a second power, and the concentration variation range may include a first preset variation range and a second preset variation range, the step S241 may include:
(1) and when the change state corresponds to a first preset change range, taking the first power as the first target power.
The odor removing device compares the odor removing substance concentration change value corresponding to the change state with a first preset change range, and when the odor removing substance concentration change value corresponding to the change state is in the first preset change range, the odor removing device is controlled to work with first power, namely the first power is used as first target power.
(2) And when the change state corresponds to a second preset change range, taking the second power as a second target power.
The odor remover compares the odor removing substance concentration change value corresponding to the change state with a second preset change range, and when the odor removing substance concentration change value corresponding to the change state is in the second preset change range, the odor remover is controlled to work with second power, namely the second power is used as the first target power.
And the minimum value of the second preset range is greater than or equal to the maximum value of the first preset range, and the relationship between the second power and the first power is determined based on the change state.
Specifically, the method for determining the relation between the second power and the first power based on the change state comprises the following steps:
1) when the change state of the concentration of the odor removing substance is in a descending state, the second power is larger than the first power.
When the change state of smell removal material concentration was for being the decline state, it was not enough to express the release of smell removal material in the current space, released promptly and is less than the consumption, need improve the work efficiency of deodorizer this moment to make deodorizer can release smell removal material fast, guarantee the peculiar smell and dispel the effect.
2) When the change state of the concentration of the odor removing substance is in an ascending state, the second power is smaller than the first power.
When the change state of the concentration of the odor removing substance is in a descending state, the odor removing substance in the current space is released more than consumed, and the working efficiency of the odor remover can be reduced so as to reduce the working energy consumption of the odor remover.
As illustrated here by way of example, assuming a plurality of sampling intervals at which concentrations of odor elimination substance are collected as S1, S2, S3, S4, respectively, the concentrations of odor elimination substance vary by values S2-S1, S3-S2, S4-S3.
If S2-S1, S3-S2 and S4-S3 are all positive values and | S2-S1| < | S3-S2| < | S4-S3|, the state of change of the concentration of the odor-removing substance is shown to be in an ascending state, and at this time, the values of S2-S1, S3-S2 and S4-S3 are judged to be in a first preset range or a second preset range. If the values of S2-S1, S3-S2 and S4-S3 are in a first preset range, controlling the deodorizer to work at a first power; and if the values of S2-S1, S3-S2 and S4-S3 are in a second preset range, controlling the deodorizer to work at a second power, wherein the second power is less than the first power.
If S2-S1, S3-S2 and S4-S3 are all negative values and | S2-S1| > | S3-S2| > | S4-S3| then the state of change of the concentration of the odor removal substance is shown to be in a descending state, and then the values of | S2-S1|, | S3-S2| and | S4-S3| are judged to be in a first preset range or a second preset range. If the values of the absolute value of S2-S1, the absolute value of S3-S2 and the absolute value of S4-S3 are in a first preset range, controlling the deodorizer to work at a first power; and if the values of the | S2-S1|, | S3-S2| and | S4-S3| are in a second preset range, controlling the deodorizer to work at a second power, wherein the second power is greater than the first power.
It should be noted that if both positive and negative values exist in S2-S1, S3-S2 and S4-S3, the singular point is determined to be deleted, and the change state of the concentration of the odor elimination substance in the current space is determined according to other change values of the concentration of the odor elimination substance.
S242, collecting the current odor elimination substance concentration after the odor elimination substance is released at the first target power.
When the deodorizer is releasing odor elimination substance at a first target power, the deodorizer can acquire the current odor elimination substance concentration in real time to determine whether the odor elimination substance concentration in the current space is increasing.
S243, judging whether the concentration of the current odor removing substance is greater than a second preset concentration value.
The second preset concentration value is larger than the first preset concentration value, and the second preset concentration value is the optimal concentration value of the odor removing substance limited in the current space. And the odor remover compares the acquired current odor removing substance concentration with a second preset concentration value to determine whether the current odor removing substance concentration is greater than the second preset concentration value. If the current concentration of odor elimination substance is greater than the second preset concentration value, step S244 is executed, otherwise, the odor eliminator is controlled to continue releasing odor elimination substance at the first target power.
S244, controlling the deodorizer to release the odor elimination substance at a second target power.
The second target power is less than the first target power. If present odor removing substance concentration is greater than the second preset concentration value, it shows that odor removing substance concentration in the current space has satisfied the odor removing requirement, can reduce the operating power of odor remover this moment, controls it to release odor removing substance with second target power, reduces odor remover's work energy consumption, avoids odor removing substance's excessive release simultaneously.
S245, collecting the current odor elimination substance concentration after the odor elimination substance is released at the second target power.
When the concentration of the current smell removing substance is greater than the second preset concentration value and the smell remover releases the smell removing substance at the second target power, the smell remover can collect the concentration of the smell removing substance after releasing the smell removing substance at the second target power in real time so as to avoid the problem of excessive release of the concentration of the smell removing substance.
S246, judging whether the concentration of the current odor removing substance is larger than a third preset concentration value, wherein the third preset concentration value is larger than the second preset concentration value.
The third preset concentration value is larger than the second preset concentration value, and the third preset concentration value is the maximum concentration value of the odor removal substance limited in the current space. And the odor remover compares the acquired current odor removing substance concentration with a third preset concentration value to determine whether the current odor removing substance concentration is greater than the third preset concentration value. If the current concentration of the odor removing substance is greater than the third preset concentration value, step S247 is executed, otherwise, the odor remover is controlled to continue releasing the odor removing substance at the second target power.
And S247, controlling the deodorizer to enter a standby state.
When the deodorizer detects that the concentration of the current odor removing substance is greater than a third preset concentration value, the odor removing substance in the current space reaches the maximum value, at the moment, in order to avoid excessive release of the odor removing substance, the deodorizer can be controlled to enter a standby state, and the deodorizer is switched to a working state until the concentration of the odor removing substance is detected to be lower than the minimum concentration value of the odor removing substance limited in the current space.
According to the control method of the deodorizer, the working power of the deodorizer for releasing the odor removing substances is determined according to the change state of the concentration of the current odor removing substances, so that the odor removing substances are released adaptively, and the excessive release of the odor removing substances is avoided.

When the deodorizer is initially in an initial working state, namely the deodorizer is initially started to enter a first working state, no odor removing substance exists in the current space. When the deodorizer is started, the deodorizer starts to release the odor removing substances into the current space, and the concentration of the odor removing substances in the current space is detected in real time. And if the concentration of the odor removing substance is less than the first preset concentration value, controlling the odor remover to release the odor removing substance at a third target power. Wherein the third target power is the maximum working power of the deodorizer.

S334, when the deodorizer is switched from the standby state to the working state and the concentration of the odor removing substance is less than the first preset concentration value, the change state of the concentration of the odor removing substance is obtained.
When the deodorizer detects that the concentration of the odor removing substances in the current space is reduced to a certain value, the deodorizer is switched from a standby state to a working state, and the concentration of the odor removing substances in the current space is continuously detected. When the deodorizer detects that the concentration of the odor removing substance is less than a first preset concentration value, the change state of the concentration of the odor removing substance in the current space can be directly acquired, so that the working power of the deodorizer can be adjusted according to the working state.
Optionally, obtaining the change in the concentration of the odor elimination substance comprises:
(1) and collecting a plurality of odor removal substance concentration values according to a preset sampling time length.
The preset sampling time is the sampling interval of the concentration of the odor removing substance, and can be determined according to an empirical value, for example, the preset sampling time can be set to be 5 s-10 s. The concentration detection sensor collects the concentration of the odor removing substances in the current space according to a preset sampling time length to obtain a plurality of concentration values of the odor removing substances.
(2) And calculating the difference of the concentration values of the odor removing substances corresponding to the adjacent preset sampling durations to obtain a plurality of change parameters corresponding to the concentration values of the odor removing substances.
The change parameters are used for representing the change of the concentration value of the odor removing substance, and the odor remover can obtain a plurality of change parameters by calculating the difference of the concentration values of the odor removing substance corresponding to adjacent preset sampling durations. For example, a plurality of odor elimination substance concentration values S1, S2, S3, S4 … … S can be obtained in sequence by sampling the odor elimination substance concentration value once at intervals of 5S by the concentration detection sensorNThereby, a plurality of variation parameters Delta S can be calculated1＝|S2-S1|，△S2＝|S3-S2|，……，△SM＝|SN-SN-1|。
(3) And determining the change state of the concentration of the odor removing substance according to the magnitude relation of the plurality of change parameters.
The deodorizer compares a plurality of change parameters, and then the change state of the concentration of the odor removing substance in the current space can be determined. Taking collected concentration values of odor removal substances S1, S2, S3 and S4 as examples, if S2-S1, S3-S2 and S4-S3 are all positive values, and delta S1<△S2<△S3Judging that the change state of the concentration of the odor removing substance is in an ascending state; if S1-S2, S2-S3 and S3-S4 are all positive values, and Δ S1＞△S2＞△S3Then, the change state of the concentration of the odor removal substance is judged to be a decrease state.
A plurality of smell removing substance concentration values are collected according to preset sampling duration, a plurality of change parameters corresponding to the plurality of smell removing substance concentration values are obtained by calculating the difference between the adjacent smell removing substance concentration values, and then the change state of the smell removing substance concentration is determined according to the size relation of the plurality of change parameters, so that the working power of the smell remover is adjusted according to the change state of the smell removing substance concentration, and the energy consumption of the smell remover is reduced on the basis that the smell removing substance concentration is within a reasonable range.
And S34, adjusting the working power of the odor eliminating device based on the change state of the concentration of the odor eliminating substance.

When the deodorizer is switched from the standby state to the working state and the concentration of the odor removing substance is less than the first preset concentration value, the change state of the concentration of the odor removing substance is directly obtained. The method obtains the change state of the concentration of the odor removing substance in the current space according to the working state of the odor remover, and is convenient for reasonably adjusting the working power of the odor remover according to the working state.
The details are explained by taking the deodorizer to release ozone as an example, in the practical use, the deodorizer is positioned in a closed space inside the refrigerator for a long time, the concentration of ozone inside the refrigerator can be gradually reduced due to the leakage caused by the opening of a refrigerator door and the lapse of time, whether the concentration of ozone in the refrigerator meets the odor removing condition at present is judged according to the detected concentration of ozone and the reduction rate of the concentration, and the power of the deodorizer can be reduced to reduce the power consumption when the concentration of ozone is increased quickly and the concentration meets a certain condition. The deodorizer may include an ozone generator and an exhaust motor, and when the concentration of ozone rises rapidly and satisfies a certain condition, the power of the ozone generator and the exhaust motor may be reduced to reduce power consumption, and specifically, the control method of the deodorizer shown in fig. 4 may be adopted to adjust the concentration of ozone in the refrigerator.
The deodorizer has working state and standby state, and the ozone generator generates and releases ozone when detecting that the ozone concentration reaches the highest concentration SM(optimum ozone concentration in the refrigerator), the generation and release of ozone are stopped and the refrigerator enters a standby state.
The parameters for setting the operating state and the standby state of the deodorizer are as follows:
(1) ozone concentration parameters: most preferablyHigh concentration of SM-limiting the maximum concentration of ozone in the refrigerator; standard concentration SB-optimum ozone concentration in the refrigerator; minimum concentration SL-limiting the minimum concentration of ozone in the refrigerator;
(2) ozone concentration variation parameters: concentration reduction rate parameter Δ SD-a parameter of how fast the ozone concentration in the refrigerator decreases; concentration rise rate parameter Δ SR-a parameter of the rise rate of the ozone concentration in the refrigerator;
(3) power: maximum power P3-ozone module and exhaust motor all work with maximum power; standard power P2-the ozone generator works with low power, the exhaust motor works with maximum power; minimum power P1-the ozone generator and the air exhaust motor all work with low power. The specific control logic of the deodorizer is shown in table 1.

When the concentration rises to the lowest concentration SLAnd at this time the concentration increase parameter DeltaSRAt 0-3 mg/m3When the odor eliminating device is started, the working power of the odor eliminating device is controlled to be reduced to P2; if a reachesTo the lowest concentration SLThe concentration rise parameter is 3-10 mg/m3Controlling the working power of the deodorizer to be reduced to P1; when the concentration rises to the standard concentration SBWhen the odor eliminating device is started, the working power of the odor eliminating device is controlled to be reduced to P1; when the concentration of ozone in the refrigerator reaches the maximum concentration SMWhen the odor remover stops working, the odor remover enters a standby state.
All loads of the deodorizer do not work in a standby state, only the concentration detection sensor samples regularly (any value in 5-10S) to obtain the current ozone concentration value, and when the ozone concentration value is higher than the minimum concentration SLThe deodorizer is kept in a standby state, and the delta S is calculated based on two sampled ozone concentration values S1 and S2D1(ii) S1-S2. DELTA.S as concentration decreasesD1Should be positive, likewise Δ S can also be calculatedD2All of S2-S3 and Δ SD3(ii) S3-S4. DELTA.S as concentration decreasesD2And Δ SD3Should be positive. When Δ S is satisfiedD1>△SD2>△SD3When the ozone concentration is in the decreased state, the ozone concentration is judged. When the concentration falls below the minimum concentration SLAnd the parameter Δ S of concentration decreaseDAt 0-3 mg/m3When the odor remover is in the working state, the odor remover works at the power P2; if the concentration falls below the minimum concentration SLTime concentration reduction parameter Δ SDIs at 3-10 mg/m3Then the deodorizer enters the active state and the power is raised to P3 for operation. When the deodorizer works for a period of time at P2 or P3, the ozone concentration rises to the standard concentration SBWhen the ozone concentration reaches the maximum concentration S, the operating power of the deodorizer is reduced to P1MWhen the odor remover stops working, the odor remover enters a standby state.
