[0061] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0062] In order to take into account the sterilization effect while avoiding over-sterilization of food in the refrigerator, an embodiment of the present invention provides a refrigerator control method, which can guide the negative ions generated by the negative ion generating module to move to the location of the food in the food storage area through the electrode plate module, thereby achieving fixed-point sterilization; fixed-point sterilization can move the negative ions to the location where they are needed, thereby avoiding over-sterilization of other foods in the refrigerator; and through directional movement, it can ensure that the food that needs to be sterilized receives a sufficient concentration of negative ions for sterilization. For details, please refer to Figure 1 , shows a flowchart of the steps of a refrigerator control method according to an embodiment of the present invention.

[0063] like Figure 1 As shown, the refrigerator control method may include the following steps:

[0064] Step 101: Obtain the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module.

[0065] In an embodiment of the present invention, the refrigerator may include a food storage area, which may be a fresh-keeping layer of the refrigerator or other layers of the refrigerator where food needs to be sterilized. The embodiment of the present invention does not limit this.

[0066] In addition to the food storage area, the refrigerator may also include a negative ion generating module and an electrode plate module for the food storage area. The negative ion generating module can be used to generate negative ions in the food storage area, thereby sterilizing the food stored in the food storage area. The electrode plate module is used to control the migration path of the negative ions generated by the negative ion generating module. Specifically, the electrode plate module can be used to generate an electric field to control the migration path of the negative ions generated by the negative ion generating module.

[0067] In practical applications, the sterilization area of ​​the target food stored in the food storage area and the location of the target food relative to the negative ion generating module in the food storage area can be obtained. The sterilization area and location information can be automatically identified and obtained by the refrigerator or input by the user, and this embodiment of the present invention is not limited thereto. The sterilization area can be the surface area of ​​the target food.

[0068] Step 102: Control the negative ion generating module to generate negative ions according to the sterilization area; and control the electrode plate module to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area according to the position information.

[0069] After determining the sterilization area, the negative ion generation module can be controlled to generate negative ions with a sterilization intensity corresponding to the area. Then, based on the position information, the electrode plate module can be controlled to direct the negative ions generated by the negative ion generation module to the location corresponding to the target food in the food storage area, thereby sterilizing the target food at a specific point. The negative ion generation module can be controlled by the refrigerator controller, or a separate controller can be provided to control the negative ion generation module, which is not limited in the present embodiment.

[0070] In an embodiment of the present invention, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module can be first obtained; then, based on the sterilization area, the negative ion generating module is controlled to generate negative ions; and, based on the position information, the electrode plate module is controlled to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area. Through an embodiment of the present invention, the negative ions generated by the negative ion generating module can be guided by the electrode plate module to the position of the food in the food storage area, thereby achieving fixed-point sterilization; fixed-point sterilization can move the negative ions to the position where they are needed, thereby avoiding over-sterilization of other foods in the refrigerator; and through directional movement, it can be ensured that the food that needs to be sterilized receives a sufficient concentration of negative ions for sterilization.

[0071] Reference Figure 2 , shows a flowchart of another refrigerator control method according to an embodiment of the present invention, which may include the following steps:

[0072] Step 201: Obtain the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module.

[0073] In some feasible embodiments, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module in the food storage area may be obtained first.

[0074] In one embodiment of the present invention, the refrigerator further comprises a detection sensor module provided for the food storage area, the detection sensor module being used to collect image data for the target food and determine position information of the target food relative to the negative ion generating module.

[0075] In some feasible embodiments, the refrigerator may also be provided with a detection sensor module, which may be used to collect image data of the target food and determine the position information of the target food relative to the negative ion generating module.

[0076] Exemplarily, the detection sensing module can be composed of a ranging sensor and a visual sensor; wherein, the ranging sensor can be used to determine the position information of the target food relative to the negative ion generating module; the visual sensor can be used to collect image data for the target food, and the image data can be used to analyze whether the target food is newly placed in the refrigerator or has been placed in the refrigerator before; it can also be used to determine the sterilization area.

[0077] In some feasible embodiments, the detection sensor may be disposed on the top of the food storage area, or may be disposed at other locations. The embodiment of the present invention does not limit the specific location of the detection sensor.

[0078] Step 202: Control the negative ion generating module to generate negative ions according to the sterilization area.

[0079] After obtaining the sterilization area, the negative ion generating module can be controlled to generate negative ions with a sterilization intensity corresponding to the area.

[0080] Step 203, the electrode plate module includes at least a first electrode plate and a second electrode plate, and the first electrode plate and the second electrode plate are connected to each other; according to the position information, the first electrode plate and / or the second electrode plate are controlled to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area.

[0081] In some feasible embodiments, the electrode plate module may include at least a first electrode plate and a second electrode plate; wherein the first electrode plate and the second electrode plate may be connected to each other. The first electrode plate may guide the movement of negative ions in a first direction, and the second electrode plate may guide the movement of negative ions in a second direction; the first direction and the second direction are perpendicular to each other. Thus, by configuring the first electrode plate and the second electrode plate, the negative ions generated by the negative ion generating module may be controlled to move in the first direction and the second direction, thereby guiding the negative ions generated by the negative ion generating module to the location corresponding to the target food in the food storage area, thereby sterilizing the target food.

[0082] Illustratively, the first electrode plate and the second electrode plate may be arranged perpendicular to each other, or may be connected and arranged at other angles α, where 0°<α<180°. The embodiment of the present invention does not limit the specific value of α.

[0083] In practical applications, after determining the position information, the first electrode plate and / or the second electrode plate can be controlled according to the position information to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area.

[0084] For example, when it is necessary to guide negative ions to move in the first direction, the first electrode plate can be controlled; when it is necessary to guide negative ions to move in the second direction, the second electrode plate can be controlled; when it is necessary to guide negative ions to move in the first direction and the second direction at the same time, the first electrode plate and the second electrode plate can be controlled. The embodiments of the present invention do not limit this.

[0085] In one embodiment of the present invention, the negative ion generating module includes a plurality of negative ion emitting holes, and the plurality of negative ion emitting holes are respectively directed toward different areas of the food storage area; the above method may further include the following steps:

[0086] According to the position information, a target emission hole is determined from a plurality of negative ion emission holes; and a negative ion generating module is controlled to emit negative ions toward the food storage area through the target emission hole.

[0087] In some feasible embodiments, the negative ion generating module may include a plurality of negative ion emitting holes, and different negative ion emitting holes have different emission angles, so as to emit negative ions to different areas of the food storage area.

[0088] For example, after the position information is determined, a negative ion emission hole closest to the target food can be determined as the target emission hole from among the multiple negative ion emission holes according to the position information.

[0089] Then, the negative ion generating module can be controlled to emit negative ions toward the food storage area through the target emission hole, so as to shorten the distance between the negative ions emitted by the negative ion generating module and the location of the target food.

[0090] In an embodiment of the present invention, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module are obtained; based on the sterilization area, the negative ion generating module is controlled to generate negative ions; the electrode plate module includes at least a first electrode plate and a second electrode plate, and the first electrode plate and the second electrode plate are connected to each other; based on the position information, the first electrode plate and / or the second electrode plate are controlled to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area. Through the embodiment of the present invention, the negative ions generated by the negative ion generating module can be guided by the electrode plate module to move to the position of the food in the food storage area, thereby achieving fixed-point sterilization; fixed-point sterilization can move the negative ions to the position where they are needed, thereby avoiding over-sterilization of other foods in the refrigerator; and through directional movement, it can be ensured that the food that needs to be sterilized receives a sufficient concentration of negative ions for sterilization.

[0091] Reference Figure 3 , shows a flowchart of another refrigerator control method according to an embodiment of the present invention, which may include the following steps:

[0092] Step 301: Obtain the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module.

[0093] In some feasible embodiments, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module in the food storage area may be obtained first.

[0094] Step 302: Control the negative ion generating module to generate negative ions according to the sterilization area.

[0095] After obtaining the sterilization area, the negative ion generating module can be controlled to generate negative ions with a sterilization intensity corresponding to the area.

[0096] Step 303: The first electrode plate includes at least one first sub-electrode plate, and the second electrode plate includes at least one second sub-electrode plate; according to the position information, the operating state of the at least one first sub-electrode plate is controlled, and / or the operating state of the at least one second sub-electrode plate is controlled to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area; the operating state includes an enabled state or a disabled state.

[0097] In some feasible embodiments, the first electrode plate may include at least one first sub-electrode plate, and the second electrode plate may also include at least one second sub-electrode plate; by controlling the operating status of the first sub-electrode plate and the second sub-electrode plate, it is possible to control whether the first sub-electrode plate and the second sub-electrode plate generate an electric field.

[0098] In actual applications, after determining the position information, the operating status of the first sub-electrode plate and / or the second sub-electrode plate can be controlled according to the position information to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area.

[0099] Exemplarily, the first sub-electrode plates may include multiple first sub-electrode plates, and multiple first sub-electrode plates may be spliced ​​into a first electrode plate. By controlling the operating state of each first sub-electrode plate, the negative ions may be controlled to move along a specific path, thereby avoiding food that has been stored in the refrigerator, thereby avoiding excessive sterilization of the food.

[0100] In an embodiment of the present invention, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module are obtained; based on the sterilization area, the negative ion generating module is controlled to generate negative ions; the first electrode plate includes at least one first sub-electrode plate, and the second electrode plate includes at least one second sub-electrode plate; based on the position information, the operating state of at least one first sub-electrode plate is controlled, and / or the operating state of at least one second sub-electrode plate is controlled to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area; the operating state includes an enabled state or a disabled state. Through the embodiment of the present invention, the negative ions generated by the negative ion generating module can be guided to the position of the food in the food storage area by the electrode plate module, thereby achieving fixed-point sterilization; fixed-point sterilization can move the negative ions to the position where they are needed, thereby avoiding over-sterilization of other foods in the refrigerator; and through directional movement, it can be ensured that the food that needs to be sterilized receives a sufficient concentration of negative ions for sterilization.

[0101] Reference Figure 4 , shows a flowchart of another refrigerator control method according to an embodiment of the present invention, which may include the following steps:

[0102] Step 401: Obtain the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module.

[0103] In some feasible embodiments, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module in the food storage area may be obtained first.

[0104] Step 402: The target food includes multiple food units, the multiple food units are stacked in a food storage area, and the storage time of different stacked layers of the multiple food units is determined.

[0105] In some feasible embodiments, the target food may include multiple food units; for example, if the target food is apple, one food unit may be one apple; and multiple apples may be stacked in the food storage area.

[0106] For example, the storage time of different stacking layers corresponding to the multiple food units can be determined based on the image data output by the detection sensor module. Specifically, the current image data can be compared with the previous image data, and then based on the comparison result, it can be determined which stacking layer contains the newly added food and which stacking layer contains the previously added food.

[0107] Step 403: Control the negative ion generating module to generate negative ions according to the storage time and sterilization area of ​​each stacked layer.

[0108] After determining the storage time of each stacked layer and the sterilization area of ​​the target food, the negative ion generating module can be controlled in a targeted manner to generate negative ions of corresponding sterilization intensity according to the storage time and sterilization area of ​​each stacked layer.

[0109] Step 404: Control the electrode plate module according to the position information to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area.

[0110] Then, the electrode plate module can be controlled based on the position information to guide the negative ions generated by the negative ion generating module to the location corresponding to the target food in the food storage area to perform targeted sterilization on the target food. The negative ion generating module can be controlled by the refrigerator controller or by a separate controller, which is not limited in the present embodiment.

[0111] In an embodiment of the present invention, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module are obtained; the target food includes multiple food units, and the multiple food units are stacked in the food storage area, and the storage time of different stacked layers of the multiple food units is determined; according to the storage time and sterilization area of ​​each stacked layer, the negative ion generating module is controlled to generate negative ions; according to the position information, the electrode plate module is controlled to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area. Through the embodiment of the present invention, the negative ions generated by the negative ion generating module can be guided by the electrode plate module to the position of the food in the food storage area, thereby achieving fixed-point sterilization; fixed-point sterilization can move the negative ions to the position where they are needed, thereby avoiding excessive sterilization of other foods in the refrigerator; and through directional movement, it can be ensured that the food that needs to be sterilized receives a sufficient concentration of negative ions for sterilization.

[0112] Reference Figure 5 , shows a flowchart of another refrigerator control method according to an embodiment of the present invention, which may include the following steps:

[0113] Step 501: Obtain the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module.

[0114] In some feasible embodiments, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module in the food storage area may be obtained first.

[0115] Step 502: Determine the storage time of different stacked layers of a plurality of food units.

[0116] In some feasible embodiments, the target food may include multiple food units. For example, the storage time of each of the multiple food units in the corresponding stacked layers can be determined based on the image data output by the detection sensor module. Specifically, the current image data can be compared with the previous image data, and based on the comparison results, the time when the food in each stacked layer was added can be determined, as well as whether the food was added currently.

[0117] If it is currently placed, the storage time corresponding to the stacking layer can be set.

[0118] Step 503: The stacking layer includes an upper layer and a lower layer. The sterilization area is the area of ​​the largest layer among the stacking layers. According to the storage time, the target food newly placed in the food storage area is determined from the upper layer and the lower layer.

[0119] In some feasible embodiments, the stacking layers are assumed to include upper and lower layers; the sterilization area can be defined as the area of ​​the largest layer among the stacking layers of target food in a region. For example, if the area of ​​the upper layer is larger than that of the lower layer, the area of ​​the upper layer can be used as the sterilization area.

[0120] After the storage time is determined, the target food newly placed in the food storage area may be determined from the upper and lower layers based on the storage time sequence.

[0121] Step 504: When the target food newly placed in the food storage area is located at the upper layer and the lower layer, a sterilization intensity having a first multiple of the sterilization area is adopted to control the negative ion generating module to generate negative ions.

[0122] For example, the negative ion generating module can be placed at the top of the food storage area. If the target food newly placed in the food storage area is located on the upper and lower layers, a sterilization intensity that is a first multiple of the sterilization area can be used to control the negative ion generating module to generate negative ions of the corresponding sterilization intensity. For example, the first multiple can be 1.2.

[0123] Step 505: When the target food newly placed in the food storage area is located in the lower layer and the sterilization area is the upper layer, a sterilization intensity that is a second multiple of the sterilization area is adopted to control the negative ion generating module to generate negative ions.

[0124] For example, if the target food newly placed in the food storage area is located on the lower layer and the sterilization area is the upper layer, since the target food on the upper layer has already been sterilized, the target food on the lower layer will be sterilized this time, but the negative ions will reach the upper layer first; therefore, to avoid over-sterilization, a negative ion concentration slightly weaker than the normal sterilization concentration can be used. For example, the second multiple can be 0.9.

[0125] Step 506: When the target food newly placed in the food storage area is located in the lower layer and the sterilization area is the lower layer, a sterilization intensity that is a third multiple of the sterilization area is adopted to control the negative ion generating module to generate negative ions.

[0126] For example, if the target food newly placed in the food storage area is located on the lower layer and the sterilization area is the lower layer, because the upper layer contains previously sterilized food and the lower layer is the target of the current sterilization, but the negative ions reach the upper layer first and the upper layer is smaller than the lower layer, to avoid over-sterilization of the upper layer, a negative ion concentration slightly weaker than the normal sterilization concentration can be used. For example, the third multiple can be 0.8.

[0127] Step 507: When the target food newly placed in the food storage area is located in the upper layer and the sterilization area is the upper layer, a sterilization intensity that is a fourth multiple of the sterilization area is adopted to control the negative ion generating module to generate negative ions.

[0128] For example, if the target food newly placed in the food storage area is located on the upper layer and the sterilization area is the upper layer, a normal sterilization concentration of negative ions can be used. For example, the fourth multiple can be 1.

[0129] Step 508. When the target food newly placed in the food storage area is located in the upper layer and the sterilization area is the lower layer, a sterilization intensity of the fifth multiple of the sterilization area is adopted to control the negative ion generating module to generate negative ions; wherein, the first multiple > the fourth multiple > the second multiple > the third multiple; the first multiple > the fourth multiple > the fifth multiple > the third multiple.

[0130] For example, if the target food newly placed in the food storage area is located on the upper layer, and the sterilization area is the lower layer, since the upper layer is smaller than the lower layer and the lower layer does not require sterilization, a slightly weaker negative ion sterilization intensity can be used. For example, the fifth multiple can be 0.95, or it can be 0.9, the same as the second multiple, and this is not limited in this embodiment of the present invention.

[0131] Step 509: Control the electrode plate module according to the position information to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area.

[0132] Then, the electrode plate module can be controlled based on the position information to guide the negative ions generated by the negative ion generating module to the location corresponding to the target food in the food storage area to perform targeted sterilization on the target food. The negative ion generating module can be controlled by the refrigerator controller or by a separate controller, which is not limited in the present embodiment.

[0133] In an embodiment of the present invention, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module are obtained; the storage time of different stacking layers of multiple food units is determined; the stacking layer includes an upper layer and a lower layer, and the sterilization area is the area of ​​the largest layer in each stacking layer; according to the storage time, the target food newly placed in the food storage area is determined from the upper layer and the lower layer; when the target food newly placed in the food storage area is located in the upper layer and the lower layer, a sterilization intensity that is a first multiple of the sterilization area is adopted to control the negative ion generating module to generate negative ions; when the target food newly placed in the food storage area is located in the lower layer and the sterilization area is the upper layer, a sterilization intensity that is a second multiple of the sterilization area is adopted to control the negative ion generating module to generate negative ions; when When the target food newly placed in the food storage area is located in the lower layer and the sterilization area is the lower layer, the sterilization intensity is the third multiple of the sterilization area, and the negative ion generating module is controlled to produce negative ions; when the target food newly placed in the food storage area is located in the upper layer and the sterilization area is the upper layer, the sterilization intensity is the fourth multiple of the sterilization area, and the negative ion generating module is controlled to produce negative ions; when the target food newly placed in the food storage area is located in the upper layer and the sterilization area is the lower layer, the sterilization intensity is the second multiple of the sterilization area, and the negative ion generating module is controlled to produce negative ions; wherein, the first multiple > the fourth multiple > the second multiple > the third multiple; according to the position information, the electrode plate module is controlled to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area. Through the embodiments of the present invention, the negative ions generated by the negative ion generating module can be guided by the electrode plate module to move to the location of the food in the food storage area, thereby achieving fixed-point sterilization; fixed-point sterilization can move the negative ions to the location where they are needed, thereby avoiding excessive sterilization of other foods in the refrigerator; and through directional movement, it can be ensured that the food that needs to be sterilized receives a sufficient concentration of negative ions for sterilization.

[0134] Moreover, negative ions with different sterilization intensities are generated based on the sterilization area, which can further avoid excessive sterilization of food.

[0135] Reference Figure 6 , shows a flowchart of another refrigerator control method according to an embodiment of the present invention, which may include the following steps:

[0136] Step 601: Obtain the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module.

[0137] In some feasible embodiments, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module in the food storage area may be obtained first.

[0138] Step 602: Control the negative ion generating module to generate negative ions according to the sterilization area.

[0139] After obtaining the sterilization area, the negative ion generating module can be controlled to generate negative ions with a sterilization intensity corresponding to the area.

[0140] Step 603: Determine the location of other foods in the food storage area.

[0141] In some feasible embodiments, the locations of other foods besides the target food in the food storage area can also be determined in order to plan the movement path of the negative ions and avoid the movement path of the negative ions passing through other foods and over-sterilizing other foods.

[0142] The other foods may refer to foods that have been previously placed in the food storage area, and the positions of the other foods in the food storage area are different from the position of the target food in the food storage area.

[0143] Step 604: Based on the location of other foods and the location information, the electrode plate module is controlled to guide the negative ions generated by the negative ion generating module to the location corresponding to the target food in the food storage area.

[0144] After determining the positions of other foods, a movement path of negative ions can be generated based on the positions and position information of other foods. The end point of the movement path can be the position corresponding to the position information, and the movement path may not pass through the positions of other foods to avoid repeated sterilization of foods that have been sterilized previously; after determining the movement path, the electrode plate module can be controlled to guide the negative ions generated by the negative ion generation module to the position corresponding to the target food in the food storage area according to the movement path.

[0145] In an embodiment of the present invention, the sterilization area of ​​the target food stored in the food storage area and the position information of the target food relative to the negative ion generating module are obtained; based on the sterilization area, the negative ion generating module is controlled to generate negative ions; the position of other foods in the food storage area is determined; based on the position of other foods and the position information, the electrode plate module is controlled to guide the negative ions generated by the negative ion generating module to the position corresponding to the target food in the food storage area. Through the embodiment of the present invention, the negative ions generated by the negative ion generating module can be guided by the electrode plate module to move to the position of the food in the food storage area, thereby achieving fixed-point sterilization; fixed-point sterilization can move the negative ions to the position where they are needed, thereby avoiding over-sterilization of other foods in the refrigerator; and through directional movement, it can be ensured that the food that needs to be sterilized receives a sufficient concentration of negative ions for sterilization.

[0146] And it can avoid re-sterilizing the food that has been sterilized.

[0147] It should be noted that for the sake of simplicity, the method embodiments are described as a series of actions. However, those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in this specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.

[0148] The embodiment of the present invention further provides a refrigerator drawer housing, which can be used in the food storage area of ​​the refrigerator; for example, the food storage area can be the fresh-keeping area of ​​the refrigerator. Figure 7 , shows a schematic structural diagram of a drawer shell for a refrigerator according to an embodiment of the present invention.

[0149] like Figure 7 As shown, a negative ion generating module 710 and an electrode plate module 720 are provided in the drawer housing 70 for the refrigerator. The electrode plate module 720 is used to control the moving path of the negative ions generated by the negative ion generating module 710, and the negative ion generating module 720 is used to generate negative ions.

[0150] In one embodiment of the present invention, the electrode plate module 720 includes at least a first electrode plate 721 and a second electrode plate 722 , and the first electrode plate 721 and the second electrode plate 722 are connected to each other.

[0151] like Figure 8a As shown, the first electrode plate 721 includes at least one first sub-electrode plate 721a ( Figure 8a Each small square in the is a first sub-electrode plate 721a); Figure 8b As shown, the second electrode plate 722 includes at least one second sub-electrode plate 722a ( Figure 8b Each small square in the grid is a second sub-electrode plate 722a).

[0152] like Figure 9 As shown, each first sub-electrode plate 721a can be provided with a switch 721b; the microcontroller 721c can control the operation state of each first sub-electrode plate 721a to be enabled or disabled by controlling the corresponding switch 721b. The microcontroller 721c can be a controller for a refrigerator drawer housing or a controller for the refrigerator itself, and this embodiment of the present invention is not limited thereto.

[0153] In practical applications, in addition to controlling the operating state, each of the first sub-electrode plate 721a and the second sub-electrode plate 722a can also be controlled in terms of voltage intensity, so that negative ions can accurately reach the designated sterilization point along the calculated path.

[0154] like Figure 10 As shown, the negative ion generating module 710 includes multiple negative ion emitting holes 711, each of which faces different areas of the food storage area. The negative ion generating module 710 can be designed as a cylinder, with multiple negative ion emitting holes 711 opened on the side. The number of negative ion emitting holes 711 is at least two, and the line connecting the two holes is perpendicular to the central axis of the refrigerator drawer housing 70.

[0155] For example, the number of negative ion emission holes 711 can be designed to be 6, and the angle between each hole is 60°.

[0156] In one embodiment of the present invention, the refrigerator further comprises a detection sensor module provided for the food storage area, the detection sensor module being used to collect image data for the target food and determine position information of the target food relative to the negative ion generating module.

[0157] like Figure 10 As shown, the detection sensing module may include a visual sensor 730 and a distance measurement sensor 740 .

[0158] For example, Figure 10 and Figure 11 As shown, the visual sensor 730 , the distance sensor 740 and the negative ion generating module 710 can form a sterilization integrated component 750 and be deployed at the top middle position of the drawer housing 70 for the refrigerator.

[0159] Exemplarily, the sterilization integrated component 750 is fixed to the refrigerator drawer housing 70 by a bayonet, and the electrical connection is completed at the same time as the fixation.

[0160] The first electrode plate 721 and the second electrode plate 722 are fixed to the refrigerator drawer housing 70 via a snap fit, achieving electrical connection while being fixed. The first electrode plate 721 and the second electrode plate 722 can be made of metal or carbon fiber.

[0161] Reference Figure 12 , shows a schematic structural diagram of a refrigerator according to an embodiment of the present invention. Figure 12 As shown, the refrigerator 1200 may include a refrigerator drawer housing as mentioned in the above embodiment, and the refrigerator drawer housing may be located in the food storage area 1210 of the refrigerator.

[0162] Reference Figures 13 to 15 , Figure 13 A schematic diagram of a workflow of an embodiment of the present invention is shown. Figure 14 Another workflow diagram of an embodiment of the present invention is shown. Figure 15 Another workflow diagram of an embodiment of the present invention is shown.

[0163] like Figure 13 As shown, after the refrigerator is powered on, the fruit and vegetable preservation system can be started normally first.

[0164] The user places fruits and vegetables (i.e., the aforementioned food) into the fruit and vegetable preservation area (i.e., the aforementioned food storage area). The visual sensor can identify the area where the fruits and vegetables are placed and feed the regional image back to the refrigerator's processor. The processor determines the sterilization area on the surface of the fruits and vegetables and divides the sterilization area into three levels: S1, S2, and S3. Different sterilization areas require different negative ion sterilization intensities. In the present invention, negative ions are generated by high-voltage discharge, and different sterilization areas correspond to different operating voltages.

[0165] Table 1: Sterilization area corresponding to negative ion intensity

[0166]

[0167] The distance sensor measures the distance between the fruit and vegetable area and the sterilization integrated assembly (i.e., the position of the fruit and vegetables relative to the negative ion generator module). This distance is divided into vertical distance Y and horizontal distance X, and the measured distance parameters are fed back to the refrigerator's processor. The refrigerator's processor calculates the shortest path between the sterilization integrated assembly 01 and the distance sensor 013 and feeds this back to the refrigerator controller.

[0168] The negative ion generating module generates negative ions from the negative ion emitting hole closest to the area where the fruits and vegetables are placed according to the calculation results.

[0169] The first electrode plate and the second electrode plate are energized and work, and different sub-electrode plates are started according to the shortest path calculated by the controller. The negative ions emitted by the negative ion emission holes are affected by the electric field and reach the storage area of ​​fruits and vegetables along the corresponding movement path.

[0170] In some possible embodiments, such as Figure 14 As shown, in order to sterilize only newly placed fruits and vegetables and avoid over-sterilization of previously placed fruits and vegetables, after placing fruits and vegetables in the fruit and vegetable preservation area, the visual sensor uploads image data to the refrigerator's processor once.

[0171] The visual sensor also takes a photo of the entire fresh-keeping area after it's been opened and closed once. The sensor then compares the photo with the previous photo stored in the refrigerator's memory to determine if new fruit or vegetables have been added. If so, the area is sterilized according to the above steps. If not, sterilization is not performed.

[0172] In the embodiment of the present invention, negative ions of a certain concentration are delivered to a specific point in the sterilization area. The negative ions exist in a certain spatial area, rather than just acting on a plane.

[0173] If the visual sensor finds food stacking during photo recognition, it will compare with the image of the last photo recognition. If the upper and lower layers of the stack are both old items (i.e., food placed earlier), sterilization will not be started; if the upper and lower layers of the stack are both new items (i.e., newly placed food), it will be started (stacking 1); if the upper layer of the stack is old items and the lower layer is new items, it will be started (stacking 2); if the upper layer of the stack is new items and the lower layer is old items, it will be started (stacking 3).

[0174] First, the visual sensor identifies the sterilization area Sn, where Sn is the larger area between the upper and lower food layers.

[0175] There are two cases here, Sn is the area corresponding to the upper items and Sn is the area corresponding to the lower items.

[0176] Compare Sn with the area S of the bottom of the refrigerator drawer shell, and obtain the initial negative ion sterilization intensity according to the negative ion sterilization intensity corresponding to the sterilization area shown in Table 1.

[0177] Stack 1 operates at a sterilization intensity 1.2 times that of the sterilization area Sn. Because both the upper and lower layers contain new items, the required negative ion concentration within the sterilization area is higher. This means that the negative ion sterilization intensity of stack 1 is 1.2 times the initial negative ion sterilization intensity.

[0178] In stack 2 mode, if Sn represents the area of ​​the upper layer, a sterilization intensity of 0.9 times the sterilization area Sn is used. Because the upper layer contains previously sterilized items and the lower layer is the target of this sterilization, and negative ions reach the upper layer first, a slightly weaker negative ion concentration than normal is used to avoid over-sterilization. In this case, the negative ion sterilization intensity is 0.9 times the initial negative ion sterilization intensity.

[0179] If Sn is the area of ​​the items on the lower layer, a sterilization intensity of 0.8 times the sterilization area Sn is used. This is because the upper layer contains previously sterilized items, while the lower layer is the target of this sterilization. However, negative ions reach the upper layer first, and the upper layer is smaller than the lower layer. Therefore, to avoid over-sterilizing the items on the upper layer, a weaker sterilization intensity is used. In this case, the negative ion sterilization intensity is 0.8 times the initial negative ion sterilization intensity.

[0180] In stacking mode 3, if Sn is the area of ​​the upper layer, the sterilization intensity corresponding to area Sn is used. Since the lower layer contains items that have already been sterilized, they do not need to be sterilized again. If Sn is the area of ​​the lower layer, a sterilization intensity 0.9 times the sterilization area Sn is used. Since the upper layer is smaller than the lower layer, and the lower layer does not require sterilization, a slightly weaker negative ion sterilization intensity is sufficient. In this case, the negative ion sterilization intensity is 0.9 times the initial negative ion sterilization intensity.
