[0025] refer to Figure 1-3 A refrigeration device with a pesticide degradation function includes a refrigeration box 3, a fruit and vegetable chamber 4 is installed at the bottom of the refrigeration box 3, an electrolytic cell 1 for spraying water mist with a pesticide degradation function is arranged above the fruit and vegetable chamber 4, and a water tank 2 is arranged above the electrolytic cell 1 and the water tank 2 is connected to the electrolytic cell 1;
[0026] The electrolytic cell 1 includes a cell body 11, on which an upper cover 12 is installed. An electrocatalytic plate 18 is installed in the electrolytic cell 1. A plurality of spray ports 16 are provided at the bottom of the cell body 11. An atomizing sheet is installed at the top of the spray ports 16 located in the cell body 11. A water absorption strip 17 is installed on the top of the atomizing sheet, and the upper part of the water absorption strip 17 extends into the electrolytic cell 1.
[0027] A cross-shaped partition plate 13 is installed in the tank body 11 , and the partition plate 13 divides the tank body 11 into four partition tanks 14 .
[0028] A connecting hole 15 is formed at the center bottom of the partition plate 13 to connect the four partition grooves 14 . A water level sensor 110 for controlling the operation of the water pump 22 and the atomizing plate is installed in one of the partition grooves 14 .
[0029] Electrocatalytic plates 18 and water absorption strips 17 are installed in the partition grooves 14, and the number of electrocatalytic plates 18 and water absorption strips 17 in each partition groove 14 is 1-5. The final number is determined according to the size of the spray area in the fruit and vegetable chamber 4. In Example 1, there are preferably 2 electrocatalytic plates 18 and water absorption strips 17 in each partition groove 14.
[0030] An outlet pipe 21 is installed at the bottom of the water tank 2. The end of the outlet pipe 21 away from the water tank 2 is connected to the water inlet end of the water pump 22. The water outlet end of the water pump 22 is connected to the water inlet pipe 19. The end of the water inlet pipe 19 away from the water pump 22 is connected to the tank body 11. The water tank 2 is a movable water tank 2. When taking it away, the outlet pipe 21 is removed. At this time, the water outlet is in a sealed state. When the outlet pipe 21 of the water tank 2 is connected to the water inlet end of the water pump 22, the water outlet below is opened, and the water pump 22 starts working, and the water in the water tank 2 is drained into the electrolytic cell 1 in a pump-suction manner.
[0031] The electrocatalytic plate 18 is loaded with titanium dioxide doped with rare earth and platinum catalysts to form a metal electrode plate. The metal electrode plate can electrolyze water in the electrolytic cell 1 to generate a large amount of hydroxyl radicals, which are then atomized into the fruit and vegetable chamber 4 in the form of a spray through the spray port 16.
[0032] The gap between the bottom surface of the electrolytic cell 1 and the top surface of the fruit and vegetable chamber 4 is 5mm-20mm. This design ensures that the sprayed water mist containing active particles quickly settles to the surface of the fruits and vegetables in the fruit and vegetable chamber 4, and prevents condensation of the water mist due to excessive distance.
[0033] Example 1:
[0034] refer to Figure 1 A fruit and vegetable chamber 4 is defined in the refrigeration box 3, so that fruits and vegetables can be stored. The electrolytic cell 1 is connected to the movable water tank 2. At the same time, a spray atomization device is installed under the electrolytic cell 1. Finally, the water in the water tank 2 is electrolytically catalyzed and then sprayed into the fruit and vegetable chamber 4 to degrade the pesticides on the surface of fruits and vegetables.
[0035] The electrolytic cell 1 of the pesticide degradation component is arranged on the fruit and vegetable chamber 4 and sprays a spray containing active ions into the fruit and vegetable chamber 4, thereby being able to degrade pesticides on the surface of fruits and vegetables.
[0036] The refrigeration box 3 refers to a device capable of storing items at low temperatures. Examples thereof include a refrigerator box that can be a refrigeration compartment or a freezer compartment, preferably a refrigeration compartment.
[0037] The pesticide degradation assembly includes a removable water tank 2, a water pump 22, and an electrolytic cell 1. The metal catalytic electrode plate in the electrolytic cell 1 is the primary component responsible for degradation. Titanium dioxide is doped with rare earth and platinum catalysts, loaded onto the electrocatalytic plate 18. This metal electrode plate electrolyzes water in the electrolytic cell 1 to generate a large amount of hydroxyl radicals, which are then atomized into the fruit and vegetable box as a spray.
[0038] Electrolyzer 1 uses vibratory atomization to generate spray. A water-absorbing strip 17 extends from the top of the atomizing plate into the interior of electrolyzer 1, and spray ports 16 are located below the atomizing plate. In this example, there are four metal catalytic electrode plates and sixteen spray ports 16.
[0039] The electrolytic cell 1 in this embodiment also includes an upper cover 12. This sealing structure prevents users from accidentally touching the internal electrical components and reduces water evaporation from the electrolytic cell 1. The gap between the electrolytic cell 1 and the fruit and vegetable compartment 4 is 5 mm, ensuring that the sprayed water mist containing active particles quickly settles on the surface of the fruits and vegetables while preventing condensation caused by the water mist.
[0040] The electrolytic cell 1 in the example of the present invention is also equipped with a water level sensor 110, and a main control board and a power board are arranged inside. The main control board is mainly used to control the water inlet of the water pump 22 and the start and stop cycle of the atomizing plate according to the water level signal in the cell body 11 returned by the water level sensor 110. Generally, the water level sensor 110 will have its own control system to realize simple signal control. Therefore, how the main control board controls the water pump 22 through the water level signal sent by the water level sensor 110 is the existing technology in this field and will not be explained in detail here. The water level sensor 110, the atomizing plate and the water pump 22 are all electrically connected to the power board.
[0041] It can be understood that the power board in the present invention can be driven by being externally connected to the refrigerator power supply. The models of the water level sensor 110, the atomizer and the water pump 22 are not limited to a single type and can be any type currently available on the market that is suitable for the present invention.
[0042] The present invention uses a metal catalytic electrode plate to electrolyze water entering the water tank to generate water rich in hydroxyl free radicals, which is then sucked into the atomizing sheet through the water absorption strip 17, and then atomized out through vibration in the form of a spray into the fruit and vegetable box. This can quickly decompose pesticides on the surface of fruits and vegetables, extend the shelf life of food, and greatly improve the food safety.
[0043] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
