[0002] With the continuous improvement of people's living standards, more and more people pay more attention to food hygiene. Since the use of pesticides is indispensable in the agricultural production process, farmers do not use pesticides according to regulations. Therefore, it is difficult to avoid excessive pesticide residues in fruits and vegetables on the market. In order to effectively degrade the residual pesticides on fruits and vegetables and reduce the pesticide residues to the safety limit that meets the national standards, some manufacturers have launched refrigerators with pesticide residue removal functions to ensure that consumers can easily obtain safe, reliable and healthy fruits and vegetables without adding additional household appliances. Common pesticide residue degradation methods include physical methods, biological methods and chemical methods. Chemical methods are suitable for refrigerators, mainly including ozone oxidation, ion degradation and ultraviolet light. Among the existing refrigerators with pesticide residue removal functions, some use a single pesticide residue degradation method, and a few use a combination of two or more methods, but the effect of pesticide residue removal is not ideal. At the same time, when using the ozone oxidation method and the ion degradation method, ozone will be generated during the working process. Ozone has a peculiar smell and is easy to cause discomfort to consumers.

DETAILED DESCRIPTION

[0044] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0046] See also Figure 1 As shown, the refrigerator with the function of removing pesticide residues of the present invention is schematically shown, comprising a box body 10, wherein the box body 10 comprises a box shell 11, a box liner 12 and an insulating layer 13 arranged therebetween, wherein a refrigerating chamber 14 is formed in the box liner 12. Figures 2 to 5As shown, a pesticide residue removal drawer 20 is provided in the refrigerating chamber 14, and the pesticide residue removal drawer 20 includes a drawer body 21, a drawer cover 22, a pesticide residue removal device 23 and an ozone degradation device 24. The drawer body 21 is slidably matched with the box liner 12. Specifically, guide rails are installed on both sides of the drawer body 21, and the corresponding position on the box liner 12 is also provided with a guide rail matched therewith, and the two work together to realize the sliding match between the drawer body 21 and the box liner 12. The drawer cover 22 is covered on the drawer body 21, and the drawer cover 22 can be sealed with the drawer body 21 to form the internal space of the sealed pesticide residue removal drawer 20. More importantly, the pesticide residue removal device 23 is provided on the drawer cover 22, and the pesticide residue removal device 23 includes an ion generator 231 and an ozone generator 232. The ion generator 231 is triggered by high voltage, and can generate a large amount of high-energy ions when powered on, and also generates ozone. The ozone generator 232 produces ozone by using the principle of high-voltage discharge, that is, applying high-voltage alternating current to high-voltage electrodes separated by an insulator and a certain gap, allowing the passing dry purified air or oxygen to pass through. When the high-voltage alternating current reaches a certain intensity, a blue glow discharge (corona) is generated, and the free high-energy ions in the corona dissociate oxygen molecules and polymerize into ozone molecules through collision. In addition, the ozone degradation device 24 can be started after the pesticide residue removal device 23 stops running, and the ozone in the drawer body 21 can be degraded to eliminate the odor caused by ozone in time.

[0047] In the refrigerator with the function of removing pesticide residues based on the above technical features, the ion generator 231 can generate ions when powered on, and the power-on triggers a large number of high-energy ions to destroy the pesticide molecular chains remaining in fruits and vegetables, and decompose them into trace elements, carbon oxides and water that are harmless to the human body. The ozone generator 232 can convert oxygen in the air into ozone when powered on. At the same time, the ion generator 231 can also produce ozone under high pressure. Ozone has strong oxidizing properties and can oxidize and degrade the organic phosphorus or carbamate pesticides remaining in fruits and vegetables, thereby realizing the combined use of the two pesticide residue removal methods of ozone oxidation and ion degradation, and achieving a better pesticide residue removal effect. The drawer cover 22 is covered on the drawer body 21 and can be sealed with the drawer body 21. The pesticide residue removal device 23 is arranged on the drawer cover 22. The pesticide residue removal device 23 works in the sealed pesticide residue removal drawer 20 to degrade the pesticides on the surface of fruits and vegetables, further improving the efficiency of pesticide residue removal. In addition, after the pesticides on the surface of fruits and vegetables are effectively removed, the ozone is reduced and degraded by the ozone degradation device 24, eliminating the user's concerns about the odor of ozone and ensuring a good user experience.

[0048] Specifically, Figure 5As shown, the pesticide residue removal device 23 also includes a base frame 233 installed on the drawer cover 22 and a cover 234 cooperating with the base frame 233. The ion generator 231 and the ozone generator 232 are both installed on the base frame 233. The cover 234 is arranged outside the base frame 233, the ion generator 231 and the ozone generator 232 to maintain a neat and beautiful appearance and improve the overall integration and space utilization of the device.

[0049] Furthermore, in this embodiment, the ion generator 231 includes an emitting needle (not shown in the figure) and a metal sheet (not shown in the figure) arranged opposite to the emitting needle. When the ion generator 231 is connected to high voltage, a high-voltage electric field is generated between the emitting needle and the metal sheet, generating a large number of ions, and additionally generating ozone to degrade the pesticides remaining on the surface of fruits and vegetables.

[0050] As a preferred embodiment, Figures 6 to 8 As shown, Figure 6 for Figure 1 The side view of the embodiment shows that the ozone degradation device 24 includes a fan 241, an air duct 242, a damper 243 and a catalyst block 244. The fan 241 is arranged on the base frame 233, the air duct 242 is arranged between the outer wall of the drawer body 21 and the rear wall of the refrigerating chamber 14, and the damper 243 can be opened or closed (in the present embodiment, the opening and closing of the damper 243 is electrically driven). When the damper 243 is closed, the sealing of the internal space of the drawer body 21 can be ensured. When the damper 243 is opened, the air duct 242 and the internal space of the drawer body 21 can be connected. The catalyst block 244 can degrade ozone and reduce ozone to oxygen. In this way, after the pesticide residues on the surface of fruits and vegetables are removed, the pesticide residue removal device 23 stops running, the fan 241 is started, and the damper 243 is opened to generate strong convection, so that the ozone filled in the internal space of the drawer body 21 enters the air duct 242, contacts and reacts with the catalyst block 244 in the air duct 242, and the ozone is degraded and reduced to oxygen. Ozone and air continue to circulate in the refrigerator 14, and the catalyst block 244 continues to degrade ozone until the ozone concentration is reduced to a concentration that the user cannot perceive, and then the fan 241 is stopped and the damper 243 is closed, thereby eliminating the impact of ozone odor on the user.

[0051] Preferably, the drawer body 21 and the drawer cover 22 are both made of materials with antioxidant properties, specifically, PMMA (polymethyl methacrylate) material, to prevent the drawer cover 22 and the drawer body 21 from aging such as yellowing and cracking after long-term use in an environment with high ozone concentration.

[0052] Further preferably, a sensor (not shown in the figure) is provided on the box body 10, and the sensor can be used to sense whether there is human activity within a certain range around the refrigerator (in the present embodiment, the range is set to 2 meters). When human activity is sensed, a feedback signal is given to the control device of the refrigerator, and the control device controls the ozone generator 232 to stop running and starts the ozone degradation device 24 to quickly reduce ozone to oxygen, thereby eliminating the impact of ozone odor on users.

[0053] To achieve the same purpose, the present invention also provides a method for controlling pesticide residue removal in a refrigerator. The control method is a specific working method of the refrigerator with the pesticide residue removal function. Fig. 9 As shown, the steps include:

[0054] S1, start the pesticide residue removal program, and power on the ion generator 231 and the ozone generator 232;

[0055] S2. Detecting the running time of the pesticide residue removal program and the opening and closing state of the refrigerator door, and controlling the operation of the ion generator 231 and the ozone generator 232 according to the running time and the opening and closing state.

[0056] Among them, the pesticide residue removal program can be started by pressing the "pesticide residue removal" function key on the refrigerator control panel. After pressing the "pesticide residue removal" function key, the ion generator 231 is powered on, and the ion generator 231 is powered on to trigger a large number of high-energy ions and produce ozone, which degrades the pesticides remaining on the surface of agricultural products such as fruits and vegetables. The ozone generator 232 is powered on, and the ozone generator 232 converts oxygen in the air into ozone, which can also degrade pesticides, thereby realizing the combined use of the ozone oxidation method and the ion degradation method to achieve a better pesticide residue removal effect. After the pesticide residue removal program is started, the running time of the pesticide residue removal program and the opening and closing state of the refrigerator door are detected, and the operation of the ion generator 231 and the ozone generator 232 is controlled according to the running time and the opening and closing state. Specifically, when the ion generator 231 and the ozone generator 232 are running stably, the voltage provided to the ion generator 231 and the ozone generator 232 is gradually increased to increase the ion and ozone concentrations in the pesticide residue removal drawer 20 to enhance the pesticide residue removal efficiency. When the residual pesticides on the surface of fruits and vegetables are removed to a certain extent, the voltage provided to the ion generator 231 and the ozone generator 232 is reduced, so that the ion and ozone concentrations in the pesticide residue removal drawer 20 are not too high and can meet the needs of pesticide residue removal, thereby avoiding the waste caused by the generation of too many unnecessary ions and ozone. After the residual pesticides on the surface of fruits and vegetables are completely removed, the ion generator 231 and the ozone generator 232 are controlled to stop working. According to the running time of the pesticide removal program, the voltage provided to the ion generator 231 and the ozone generator 232 is set in steps to match the residual pesticide intensity on the surface of fruits and vegetables in the pesticide removal drawer 20, better ensure the efficiency of pesticide removal, and take into account the efficiency of energy utilization, and the working method is more scientific and reasonable. During the whole process of the pesticide removal program, if it is detected that the user opens the refrigerator door, the ion generator 231 and the ozone generator 232 are immediately controlled to forcibly stop working to avoid affecting the user. In actual use, in order to ensure safety, if the user needs to open the refrigerator door during the operation of the pesticide removal program, he can also press the "pesticide removal" function key to stop the pesticide removal program first, and then open the refrigerator door.

[0057] Preferably, before step S1, the step is further included: S0, setting the operation cycle of the pesticide residue removal program. Further preferably, the operation cycle includes a first preset time t1, a second preset time t2, a third preset time t3, a fourth preset time t4 and an end time t5, wherein when the pesticide residue removal program runs to the first preset time t1, the first voltage boost is performed; when it runs to the second preset time t2, the second voltage boost is performed; when it runs to the third preset time t3, the voltage is reduced; when it runs to the fourth preset time t4, the ion generator 231 and the ozone generator 232 stop working, and the ozone degradation device 24 is operated; when it runs to the end time t5, the ozone degradation device 24 stops working, completing the entire pesticide residue removal cycle. Specifically, step S2 includes the following steps:

[0058] S21, obtaining the running time of the pesticide residue removal program, and determining whether it reaches the first preset time t1, if not, continuing to obtain the running time of the pesticide residue removal program; if so, obtaining the opening and closing state of the refrigerator door, and determining whether it is open, if so, controlling the ion generator 231 and the ozone generator 232 to stop working, if not, increasing the voltage provided to the ion generator 231 and the ozone generator 232;

[0059] S22, obtaining the running time of the pesticide residue removal program, and determining whether it reaches the second preset time t2, if not, continuing to obtain the running time of the pesticide residue removal program; if so, obtaining the opening and closing state of the refrigerator door, and determining whether it is open, if so, controlling the ion generator 231 and the ozone generator 232 to stop working, if not, continuing to increase the voltage provided to the ion generator 231 and the ozone generator 232.

[0060] S23, obtaining the running time of the pesticide residue removal program, and determining whether it reaches the third preset time t3, if not, continuing to obtain the running time of the pesticide residue removal program; if so, obtaining the opening and closing state of the refrigerator door, and determining whether it is open, if so, controlling the ion generator 231 and the ozone generator 232 to stop working, if not, reducing the voltage provided to the ion generator 231 and the ozone generator 232.

[0061] In this embodiment, the operating cycle of a pesticide removal program is set to 2 hours (i.e., the end time t5 is 120 minutes), the first preset time is set to 15 minutes, the second preset time is set to 45 minutes, and the third preset time is set to 105 minutes. After the pesticide removal program is started in step S1, the voltages provided to the ion generator 231 and the ozone generator 232 are 4kv and 6kv respectively, so that the ion generator 231 and the ozone generator 232 can work stably. When the pesticide removal program continues to run for the first preset time t1 (15 minutes), if the refrigerator door is not opened, the voltages provided to the ion generator 231 and the ozone generator 232 are increased to 6kv and 10kv respectively, so as to improve the generation efficiency of ions and ozone, and enhance the intensity and efficiency of pesticide removal. When the pesticide residue removal program continues to run for the second preset time t2 (45 minutes), if the refrigerator door is not opened, the voltage provided to the ion generator 231 and the ozone generator 232 will be increased to 10kv and 15kv respectively to further improve the intensity and efficiency of pesticide residue removal. When the pesticide residue removal program continues to run for the third preset time t3 (105 minutes), most of the residual pesticides on the surface of fruits and vegetables have been degraded. If the refrigerator door is not opened, the voltage provided to the ion generator 231 and the ozone generator 232 will be reduced to 4kv and 6kv respectively to reduce the concentration of ions and ozone, which is sufficient to ensure that the residual pesticides on fruits and vegetables are completely degraded, avoiding the generation of excessive ions and ozone to cause unnecessary waste.

[0062] Preferably, after step S2, step S3 is also included: obtaining the running time of the pesticide residue removal program, and determining whether it reaches a fourth preset time t4 (preferably, the interval between the fourth preset time t4 and the end time t5 is 4 to 8 minutes. In the present embodiment, t4 is set to 115 minutes). If not, continue to obtain the running time of the pesticide residue removal program; if so, control the ion generator 231 and the ozone generator 232 to stop working, start the fan 241, and open the damper 243 until the running time of the pesticide residue removal program reaches the end time t5, and stop the fan 241 and the damper 243.

[0063] That is, when the pesticide residue removal program continues to run for the fourth preset time t4 (115 minutes in this embodiment), the residual pesticides on the surface of fruits and vegetables have been degraded to a safe range, the ion generator 231 and the ozone generator 232 are controlled to stop working, the fan 241 is started, and the damper 243 is opened to perform ozone degradation until the pesticide residue removal program runs to the end time t5 (120 minutes). At this time, the ozone has been degraded to a concentration that is imperceptible to the user, the fan 241 and the damper 243 are controlled to stop working, and the entire pesticide residue removal program is completed.

[0064] The interval between the fourth preset time t4 and the end time t5 is 4 to 8 minutes, and the interval time is the time for degrading ozone. Within this time range, the ozone in the pesticide residue removal drawer 20 can be degraded to a concentration that is imperceptible to the user.

[0065] In summary, the refrigerator with the function of removing pesticide residues of the present invention has a pesticide residue removal device including an ion generator and an ozone generator. The ion generator can generate ions when powered on, and a large number of high-energy ions are triggered when powered on, which can decompose the pesticide residues remaining in fruits and vegetables. The ozone generator can convert oxygen into ozone when powered on. At the same time, the ion generator can generate ozone under high pressure, and ozone can also oxidize and degrade the pesticide residues remaining in fruits and vegetables, thereby realizing the combined use of the two pesticide residue removal methods of ozone oxidation and ion degradation to achieve a better pesticide residue removal effect. The pesticide residue removal device works in a sealed pesticide residue removal drawer, which further improves the efficiency of pesticide residue removal. In addition, after effectively removing the pesticides on the surface of fruits and vegetables, the ozone degradation device is used to reduce and degrade the ozone, eliminating the user's concerns about the odor of ozone and ensuring a good user experience.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
