Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions of the present invention will be described clearly and completely below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. 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.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Fig. 1 is a schematic diagram of an electric control module of the deodorizer, a battery 11 of the deodorizer supplies power to a main control chip 10 through a power management circuit 12, and the main control chip 10 is respectively connected with a key and display module 13, a fan 14 and an ozone generator 15. The main control chip 10 receives a control command of the key 131 of the key and display module 13, and sends out a control command to control the fan 14 and the ozone generator 15 to be turned on or off, and displays the current working state of the deodorizer on the display module 132 of the key and display module 13.
Further, some deodorizers are also provided with an ozone concentration sensor 16 for monitoring the concentration of ozone in the space to be deodorized in real time, and the main control chip 10 is further configured to control the on/off of the fan 14 and the ozone generator 15 according to the concentration of ozone in the space to be deodorized. However, the ozone concentration sensor 16 is expensive, and the use in the deodorizer greatly increases the price of the deodorizer, so that the ozone concentration sensor is not common in the existing deodorizer applied to the refrigerator.
Furthermore, as the main functional modules and the energy consumption modules of the deodorizer are the ozone generator 15 and the fan 14, the reasonable control of the working time of the ozone generator 15 and the fan 14 is a main means for saving the power consumption of the battery 11 and increasing the endurance time. Tests prove that when the ozone concentration of the space to be deodorized reaches a certain value, even if the generation of ozone is stopped, the number of bacterial colonies in the space to be deodorized is reduced to an extremely low number after a certain time, and the extremely low number is maintained for a long time. Based on the test results, the ozone concentration of the space to be deodorized does not need to be monitored in real time, and the satisfactory sterilization effect can be achieved by reasonably controlling the operation period and the standby period of the deodorizer. In view of this, the invention provides an energy-saving control method for a deodorizer.
FIG. 2 is a flow chart of an energy-saving control method of the deodorizer according to the embodiment of the present invention. As shown in fig. 2, in the technical solution of this embodiment, an energy-saving control method for a deodorizer includes the following steps:
s0, dividing the operation cycle of the deodorizer into a deodorization stage and an air purification stage;
s1, in a smell removal stage, controlling the ozone generator 15 and the fan 14 to be started and operate according to preset working parameters so as to enable the concentration of ozone in a space to be smell removed to be greater than or equal to a preset concentration threshold value;
in the embodiment of the present invention, the ozone generator 15 includes an ozone generating element and an ozone generating driving circuit for driving the ozone generating element to generate ozone, the ozone generating element is a ceramic ozone element, a point discharge type ozone element, a glass tube type ozone generating element, and the like, and the ozone generating driving circuit connects a high voltage alternating current to the ozone generating element to cause the ozone generating element to break down air to generate ozone. The fan 14 is arranged in the deodorizer, the fan 14 blows air to the ozone ceramic pieces which generate ozone gas, and the ozone ceramic pieces generate as much ozone gas as possible by increasing air flow so that the concentration of ozone in the space to be deodorized is greater than or equal to a preset concentration threshold;
further, the preset working parameters comprise a target ozone generation rate, a target fan rotating speed and odor removal working time; the controlling the start of the ozone generator 15 and the fan 14 and the operation according to preset working parameters comprises: and controlling the ozone generator 15 and the fan 14 to be started simultaneously and continuously operate the deodorization working period, controlling the ozone generator 15 to operate according to the target ozone generation rate and controlling the fan 14 to operate according to the target fan rotating speed in the continuous operation process.
Further, making the concentration of ozone in the space to be deodorized greater than or equal to a preset concentration threshold value includes selecting a proper gear according to the capacity of the space to be deodorized, or configuring deodorizers of corresponding models for refrigerators of different capacities, controlling the ozone generator 15 to continuously operate the fan 14 at a target fan rotation speed for a first preset time at a target ozone generation rate, so that the ozone generated by the deodorizer reaches a target ozone amount, and further making the concentration of ozone in the space to be deodorized greater than or equal to the preset concentration threshold value.
The value of the first preset time can be selected from 3min-8min, so that the concentration of ozone in the space to be deodorized is greater than or equal to a preset concentration threshold value.
S2, in the air purification stage, controlling the ozone generator 15 to stop working, and keeping the fan 14 running continuously so as to balance the ozone concentration inside the deodorizer and in the space to be deodorized.
At present, when the ozone generator 15 stops working, the fan 14 stops working. However, the ozone inside the deodorizer is not completely blown out of the deodorizer, which not only causes the concentration of ozone inside the deodorizer and the space to be deodorized to be unbalanced, but also causes the corrosion of the injection molding and the controller inside the deodorizer because the residual ozone is retained inside the deodorizer. Therefore, after the ozone generator 15 stops operating, the embodiment of the present invention controls the fan 14 to continuously operate at the target fan speed for a second preset time period. Through tests, the value of the second preset time is 3s-120s, so that the ozone concentration in the deodorizer and the space to be deodorized can be effectively balanced.
In another embodiment of the present invention, the deodorizer further comprises an ozone concentration sensor 16, and for the deodorizer provided with the ozone concentration sensor 16, the ozone concentration sensor 16 can also detect the ozone concentration in the space to be deodorized in real time in the deodorization stage, and when the ozone concentration reaches a preset concentration threshold, the ozone generator 15 is controlled to stop working, and the air purification stage is entered.
In order to further achieve the effect of saving energy consumption, the deodorizer provided with the ozone concentration sensor 16 stops detecting the ozone concentration in the space to be deodorized after controlling the ozone generator 15 to stop working.
It should be noted that the energy-saving control method of the odor remover of the embodiment of the invention can be an energy-saving control function on the odor remover, and when the energy-saving trigger instruction is triggered by a key, the odor remover is controlled to operate an energy-saving control mode; the energy-saving control odor remover can also be an energy-saving control odor remover, and when the odor remover is started, the energy-saving control instruction is directly triggered to control the odor remover to operate the energy-saving control method.
Furthermore, tests have proved that after the concentration of ozone in the space to be deodorized reaches the concentration of ozone meeting the requirement of deodorization, the number of colonies in the space to be deodorized can be continuously kept to be extremely low even if the generation of ozone is stopped, so that the deodorizing device does not need to be frequently controlled to be started, and a good sterilizing effect can be achieved.
Thus, the control of the deodorizer to operate according to the energy-saving operating mode of the embodiment of the present invention includes a standby period in addition to the deodorization operation of controlling the deodorizer to perform an operating period. The energy-saving operating mode thus also comprises a step S3 not shown in fig. 2:
and S3, controlling the deodorizer to stop working in the standby period.
In the embodiment of the present invention, after the fan 14 continuously operates for the second preset time period in step S2, the fan 14 is controlled to stop operating, that is, to enter the standby stage.
Furthermore, one operating cycle and one standby cycle of the deodorizer form a working cycle, the duration of the working cycle is a third preset time, and the value of the third preset time is 300-600 min.
Further, after the standby period is finished, controlling the deodorizer to execute the step S1 again. The energy-saving control method of the deodorizer is the circulation of the energy-saving control working period until the deodorizer exits the energy-saving control mode.
FIG. 3 is a schematic diagram of the colony versus time for an odor elimination phase of an odor eliminator of the present invention for a period of 3 min. As can be seen from FIG. 3, the ozone generator 15 is turned on for 0min-3min, the number of colonies in the space to be deodorized is reduced to a very low number after 20min, and the very low number is maintained for 500min.
FIG. 4 is a schematic diagram of the colony versus time for an odor elimination phase of an odor eliminator of the present invention for a period of 4 min. As can be seen from FIG. 4, the ozone generator 15 is turned on for 0min to 4min, and the number of colonies in the space to be deodorized is reduced to a very low number after 20min, and the very low number is maintained for 500min.
It should be noted that, in the test process, the refrigerator door is controlled to open and close twice in the test period to simulate the actual use condition of the refrigerator, so as to further ensure the reliability of the test data.
As shown in fig. 3 and 4, the ozone generator 15 of the deodorizer is turned on for 3min and 4min, which does not significantly improve the sterilization effect, but increases the energy consumption. Therefore, in view of energy saving, the ozone generator 15 of the deodorizer can be started for 3min to achieve the effective balance of the sterilization effect and the energy saving.
With reference to the test results of fig. 3 and 4, the present invention provides an embodiment of an energy saving control method for a deodorizer, the energy saving control method comprises the following steps:
s51, receiving an energy-saving trigger signal;
s52, simultaneously starting the ozone generator 15 and the fan 14, operating according to preset working parameters, and starting timing by using a timer;
s53, when the timing duration reaches 3min, controlling the ozone generator 15 to stop working;
s54, when the timing duration reaches 3min and 4S, controlling the fan 14 to stop working;
and S55, when the timing duration reaches 480min, clearing the timer, and returning to the step S52 again.
It should be noted that, after a lot of experiments, after the ozone generator 15 stops working, the fan 14 continues to work for 4 seconds to make the ozone concentration in the deodorizer the same as that in the space to be deodorized, so it is reasonable to set the time delay of turning off the fan 14 to 4 seconds.
Further, although the colony count of the space to be deodorized in the test process is kept at an extremely low number within 500min after the ozone generator 15 is started, in order to leave a certain margin, one working period of the deodorizer is set to 480min.
Further, taking the capacity of the battery 11 of the deodorizer as 2600mAH as an example, the endurance time of the deodorizer in the energy saving control mode is calculated. The working current of the deodorizer in the deodorizing stage is 600mA, the working time of one working cycle is 3min, and the power consumption of the deodorizer in the deodorizing stage of one working cycle is 30mAH; when the fan 14 works alone, the working current is 100mA, the working time of one working cycle is 4s, and the power consumption of the air purification stage of one working cycle is 0.111mAH; the working current in the standby stage is 0.7mA, the standby time of one working cycle is 7H55min56s, and the power consumption in the standby stage of one working cycle is 5.554mAH; the total power consumption of the deodorizer in one working cycle is 35.665mAH by calculation, and when the battery capacity is 2600mAH, the deodorizer can work for 72.9 working cycles; and as one working period is 480min, the duration of the deodorizer is calculated to be up to 24.3 days. If the deodorizer continuously works, the travel can only be continued for 4.3H, and the travel continuation capability is greatly improved. Compared with the control mode of the deodorizer on the market, the duration time is varied from several days to more than ten days, and the duration capability is obviously improved.
Fig. 5 schematically shows an energy-saving control device of a deodorizer according to an embodiment of the present invention, and referring to fig. 5, the energy-saving control device of a deodorizer according to an embodiment of the present invention specifically includes a configuration unit 501 and a control unit 502, wherein:
a configuration unit 501, configured to divide the operation cycle of the deodorizer into a deodorization stage and an air purification stage;
