Description

Technical Field

[0001] This application relates to the technical field, and in particular to a refrigerator. Background Technology

[0002] Refrigerators, due to the long-term storage of various foods, are prone to bacterial growth inside. To address this issue, most refrigerators are equipped with ion sterilization components. Ion sterilization involves generating ions by ionizing the air with high voltage. Once the ions reach a certain concentration, they easily adhere to the surface of bacteria, disrupting their molecular protein structure and thus killing the bacteria and viruses.

[0003] In typical refrigerator structures, the ion sterilization module is fixed inside the refrigerator's cooling duct. The ions generated by this module are carried by the airflow during cooling to the refrigerator's interior for sterilization. However, this method means the ion sterilization module only operates when the cooling duct is running; it cannot function when the duct is not blowing air. In winter or low ambient temperatures, when the refrigerator's operating rate is low and the cooling duct's airflow time is short, the ion sterilization module's working time is very short, allowing bacteria to multiply rapidly inside the refrigerator, affecting the sterilization effect. Furthermore, the ion concentration blown into every corner of the refrigerator during cooling is fixed and cannot be adjusted. Some corners inside the refrigerator may not have sufficient ion concentration, allowing bacteria to survive and multiply, resulting in inadequate sterilization. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator that can improve the sterilization effect.

[0005] A refrigerator includes a cabinet and a sterilization system. The cabinet has multiple storage areas, each with an air inlet. The sterilization system includes an air damper and an ion sterilization module. The ion sterilization module is installed inside the air damper, which is mounted on the cabinet. An air outlet is provided on the side wall of the air damper. The air outlet is configured to switch positions among the multiple air inlets and connect with one of the air inlets, so that the ion sterilization module can provide sterilizing air to a corresponding storage area through the air outlet and the air inlet.

[0006] In one embodiment, the sterilization system further includes a fan installed inside an air damper, located on the side of the ion sterilization module opposite to the air outlet. Multiple storage areas are arranged along the height z-direction of the housing, and multiple air inlets are also arranged along the height z-direction of the housing. The air damper includes a first shell and a second shell, the second shell being fixedly connected to the housing, and the first shell being movably fitted to the second shell along the height z-direction of the housing. The air outlet is located in the first shell.

[0007] In one embodiment, the refrigerator further includes a drive mechanism for driving the first shell to move along the height direction z of the cabinet, so that the air outlet switches positions between multiple air inlets.

[0008] In one embodiment, the first shell is located above the second shell along the height direction of the housing; the driving mechanism includes an electromagnet and a first magnetic component, the first magnetic component is fixedly installed in the first shell, the electromagnet is fixedly installed in the housing, and the electromagnet is located above the first magnetic component along the height direction z of the housing; wherein, as the magnitude of the current flowing through the electromagnet changes, the first magnetic component can respond to the force between itself and the electromagnet and drive the first shell to move toward or away from the electromagnet.

[0009] In one embodiment, a limiting plate is provided inside the second shell, an elastic element is located inside the damper, and one end of the elastic element is connected to the top wall of the first shell, while the other end is connected to the limiting plate.

[0010] In one embodiment, the drive mechanism further includes a support rod, one end of which is fixedly connected to the top wall of the housing, and the other end extends downward along the height direction z of the housing, with an electromagnet fixedly installed on the support rod.

[0011] In one embodiment, the storage area and the number of air inlets are both configured to be three. The three air inlets are defined as the first air inlet, the second air inlet, and the third air inlet from bottom to top along the height direction of the box. When the electromagnet is de-energized, the air outlet is connected to the first air inlet, and the elastic element is in a compressed state. A proximity switch is provided at the second air inlet. When the first shell moves to the point where the air outlet is connected to the second air inlet, the proximity switch is triggered, and the current flowing through the electromagnet remains unchanged. One end of the support rod near the first shell is suspended. When the air outlet is connected to the third air inlet, the suspended end of the support rod abuts against the first magnetic element, and the elastic element is in a stretched state.

[0012] In one embodiment, one of the first shell and the second shell is provided with a sliding groove, and the side wall of the other shell is movably inserted into the sliding groove along the height direction z of the box.

[0013] In one embodiment, each storage area is equipped with a detection module, which is used to detect the storage status of food ingredients in the corresponding storage area.

[0014] The refrigerator provided in this application, by installing an ion sterilization module inside the air damper, allows ions generated by the module to be delivered to the corresponding storage area through the damper. Compared to related structures that install the ion sterilization module in the refrigerator's refrigeration duct, the operation of the ion sterilization module in this application does not depend on the activation of the refrigeration duct. Even when the refrigerator's refrigeration duct is not working, the ion sterilization module can still provide sterilizing air to the corresponding storage area through the damper. Furthermore, because the air outlet can switch positions among multiple air inlets and connect to one of them, that is, the air outlet can selectively connect to one storage area, the ion sterilization module can concentrate on sterilizing one storage area at a time, thus helping the ions in that storage area to quickly reach a sufficient concentration to kill bacteria in one go. In this way, the interior of the refrigerator can be sterilized in a zoned, multi-stage, thorough, and precise manner, thereby effectively improving the sterilization effect. In actual use of the refrigerator, the air inlet connected to the air outlet can be flexibly selected according to the sterilization requirements of different storage areas. For example, when a large amount of food is placed in a storage area at once, the air outlet can be switched to connect with the air inlet on that storage area, thereby conducting concentrated and thorough sterilization of that storage area.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figures 1 to 2 This application provides a refrigerator 100, which includes a cabinet 10 and a sterilization system 20. The cabinet 10 has multiple storage areas 110 inside, and each storage area 110 has an air inlet 111. The sterilization system 20 includes an air damper 210 and an ion sterilization module 220. The ion sterilization module 220 is installed inside the air damper 210, which is installed in the cabinet 10. An air outlet 211 is provided on the side wall of the air damper 210. The air outlet 211 is configured to switch positions among the multiple air inlets 111 and communicate with one of the air inlets 111, so that the ion sterilization module 220 provides sterilization air to the corresponding storage area 110 through the air outlet 211 and the air inlet 111.

[0029] It is understandable that by installing the ion sterilization module 220 inside the damper 210, the ions generated by the ion sterilization module 220 can be transported to the corresponding storage area 110 through the damper 210. Compared to related structures that install the ion sterilization module in the refrigerator's refrigeration duct, the operation of the ion sterilization module 220 in this application does not depend on the activation of the refrigeration duct. When the refrigerator's refrigeration duct is not working, the ion sterilization module 220 can still provide sterilizing air to the corresponding storage area 110 through the damper 210. Furthermore, since the air outlet 211 can switch positions among multiple air inlets 111 and connect with one of them, that is, the air outlet 211 can selectively connect with one of the storage areas 110, the ion sterilization module 220 can concentrate on sterilizing one storage area 110 at a time, thereby helping the ions in the storage area 110 to quickly reach a sufficient concentration and kill the bacteria in the storage area 110 in one go. In this way, the interior of the refrigerator 10 can be sterilized in a zoned, phased, thorough, and precise manner, thereby effectively improving the sterilization effect. When actually using the refrigerator 100, the air inlet 111 connected to the air outlet 211 can be flexibly selected according to the sterilization needs of different storage areas 110. For example, when a large amount of food is placed in a storage area 110 at once, the air outlet 211 can be switched to connect with the air inlet 111 on that storage area 110, thereby achieving concentrated and thorough sterilization of that storage area 110.

[0030] Specifically, the housing 10 has a compartment 101, and the compartment 101 is provided with multiple partitions 120. The multiple partitions 120 are spaced apart in the compartment 101 and divide the compartment 101 into multiple storage areas 110. The air door 210 can be installed on the back of the compartment 101.

[0031] The sterilization system 20 also includes a fan 230, which is installed inside the damper 210 and located on the side of the ion sterilization module 220 away from the air outlet 211. This allows the fan 230 to blow the ions generated by the ion sterilization module 220 into the corresponding storage area 110.

[0032] Alternatively, in one embodiment, as Figure 3 and Figure 4 As shown, multiple storage areas 110 are located within the cold storage room, arranged along the height z direction of the cabinet 10, and multiple air inlets 111 are also arranged along the height z direction of the cabinet 10. The air vent 210 includes a first shell 212 and a second shell 213. The second shell 213 is fixedly connected to the cabinet 10, and the first shell 212 is movably fitted to the second shell 213 along the height z direction of the cabinet 10. The air outlet 211 is located in the first shell 212, and the fan 230 and the ion sterilization module 220 are both installed inside the second shell 213. In this embodiment, the first shell 212 and the second shell 213 enclose each other to form the air vent 210. Since the air outlet 211 is located in the first shell 212, by moving the first shell 212 along the height z direction of the cabinet 10, the position of the air outlet 211 can be adjusted along the height z direction of the cabinet 10, thus facilitating the switching of the air outlet 211 between the multiple air inlets 111.

[0033] In one embodiment, one of the first shell 212 and the second shell 213 is provided with a sliding groove 215, and the side wall of the other shell is movably inserted into the sliding groove 215 along the height direction z of the housing 10. In this way, the sliding groove 215 can guide the first shell 212 and the second shell 213 to slide along the height direction of the housing 10, thereby making the first shell 212 switch positions more smoothly among the multiple air outlets 211.

[0034] The refrigerator also includes a drive mechanism 30, which drives the first shell 212 to move along the height direction z of the cabinet 10 so that the air outlet 211 switches positions between multiple air inlets 111.

[0035] Alternatively, in one embodiment, as Figure 2As shown, the first shell 212 is positioned above the second shell 213 along the height direction of the housing 10. The driving mechanism 30 includes an electromagnet 310 and a first magnetic component 320. The first magnetic component 320 is fixedly installed on the first shell 212, and the electromagnet 310 is fixedly installed on the housing 10, with the electromagnet 310 positioned above the first magnetic component 320 along the height direction z of the housing 10. As the magnitude of the current flowing through the electromagnet 310 changes, the first magnetic component 320 can respond to the force between itself and the electromagnet 310, causing the first shell 212 to move towards or away from the electromagnet 310. It should be noted that the electromagnet 310 is a device that generates electromagnetic fields when energized. Furthermore, the greater the current flowing through the electromagnet 310, the stronger its magnetism. The first magnetic component 320 can be configured as a magnet or an iron component. By changing the magnitude of the current flowing through the electromagnet 310, the electromagnet 310 can generate different forces on the first magnetic component 320, thereby enabling the first magnetic component 320 to drive the first shell 212 to move toward or away from the electromagnet 310.

[0036] Of course, in other embodiments, the drive mechanism 30 may also be configured to include a motor, a screw, and a nut. The screw extends along the height direction z of the housing 10, and the nut is fixedly connected to the first housing 212 and threadedly connected to the screw. The motor drives the screw to rotate, and when the screw rotates, the nut can move along the screw. This allows the first housing 212 to move along the height direction of the housing 10.

[0037] Furthermore, such as Figure 5 As shown, the drive mechanism 30 also includes an elastic element 330. A limiting plate 214 is provided inside the second shell 213. The elastic element 330 is located inside the damper 210. One end of the elastic element 330 is connected to the top wall of the first shell 212, and the other end is connected to the limiting plate 214. It can be understood that as the first shell 212 moves to different positions along the height direction z of the housing 10, the elastic element 330 is stretched or compressed along the height direction of the housing 10, thereby accumulating elastic potential energy. The elastic potential energy accumulated by the elastic element 330 can be used to provide elastic force to the first shell 212 to stabilize the first shell 212 in a certain position. The elastic potential energy accumulated by the elastic element 330 can also be used to drive the first shell 212 back to the initial position. For details, please refer to the explanation below.

[0038] Specifically, the limiting plate 214 is positioned above the ion sterilization module 220 along the height z direction of the housing 10, and the limiting plate 214 and the ion sterilization module 220 are spaced apart. The elastic element 330 is configured as a spring, with one end of the spring fixedly connected to the top wall of the first housing 212 and the other end fixedly connected to the limiting plate 214.

[0039] like Figure 5As shown, the drive mechanism 30 also includes a support rod 340. One end of the support rod 340 is fixedly connected to the top wall of the housing 10, and the other end extends downward along the height direction z of the housing 10. The electromagnet 310 is fixedly installed on the support rod 340. It can be understood that the support rod 340 is used to provide an installation position for the electromagnet 310, thereby facilitating the fixed installation of the electromagnet 310 to the top wall of the housing 10.

[0040] Optionally, the electromagnet 310 is configured as a ring structure, and the electromagnet 310 is fixedly sleeved on the outer periphery of the support rod 340.

[0041] Exemplarily, in one embodiment, please refer to Figure 2 , Figure 5 as well as Figure 6 The storage area 110 and the number of air inlets 111 are both configured to be three. Defined along the height direction of the housing 10, from bottom to top, the three air inlets 111 are the first air inlet 112, the second air inlet 113, and the third air inlet 114. When the electromagnet 310 is de-energized, the air outlet 211 connects with the first air inlet 112, and at this time, the elastic element 330 is in a compressed state. A proximity switch 115 is provided at the second air inlet 113. When the first housing 212 moves to the point where the air outlet 211 connects with the second air inlet 113, the proximity switch 115 is triggered, and the current flowing through the electromagnet 310 remains constant. One end of the support rod 340 near the first housing 212 is suspended. When the air outlet 211 connects with the first air inlet 112, the suspended end of the support rod 340 abuts against the first magnetic element 320, and the elastic element 330 is in a stretched state.

[0042] Specifically, the switching process of the air outlet 211 between the first air inlet 112, the second air inlet 113 and the third air inlet 114 is as follows: When the electromagnet 310 is de-energized, under the action of the gravity of the first magnetic component 320 and the gravity of the first shell 212 itself, the first shell 212 is located at the bottom, the air outlet 211 is connected to the first air inlet 112, and at this time the elastic component 330 is in a compressed state. When the electromagnet 310 is energized and the current flowing through it gradually increases, the magnetism of the electromagnet 310 gradually strengthens. When the force exerted by the electromagnet 310 on the first magnetic component 320 is greater than the weight of the first magnetic component 320 and the weight of the first shell 212, the first magnetic component 320 and the first shell 212 will move upward along the height direction z of the box 10. The current flowing through the electromagnet 310 continues to increase, and the first shell 212, the first magnetic component 320 and the first shell 212 move upward along the height direction z of the box 10, and the elastic component 330 is gradually stretched until the air outlet 211 is connected to the second air inlet 113. At this time, the proximity switch 115 is triggered and the magnitude of the current flowing through the electromagnet 310 remains unchanged, so that the first shell 212 is balanced by force and remains in a fixed position. At this time, the storage area 110 located in the middle can be sterilized. As the current flowing through the electromagnet 310 continues to increase, the first magnetic component 320 and the first shell 212 will continue to move upward along the height direction z of the housing 10 until the air outlet 211 connects with the third air inlet 114. At this time, the suspended end of the support rod 340 abuts against the first magnetic component 320, that is, the suspended end of the support rod 340 and the first magnetic component 320 limit the maximum height that the first shell 212 can move upward along the height direction z of the housing 10. At this time, if the electromagnet 310 is de-energized, the first magnetic component 320 and the first shell 212 will move under the action of gravity and the pulling force of the elastic component 330 until they connect with the first air inlet 112.

[0043] Optionally, in one embodiment, the proximity switch is configured as a Hall effect switch, and a second magnetic element 216 is mounted on the side wall of the first housing 212. When the first housing 212 moves to a position where the Hall effect switch approaches the second magnetic element 216, the Hall effect switch is triggered. It should be noted that a Hall effect switch is a magnetic induction electronic device based on the Hall effect, mainly used for non-contact detection of changes in magnetic fields and conversion into electrical signals. It is widely used in position detection, speed measurement, and safety control. Of course, in other embodiments, the proximity switch can also be configured as a photoelectric proximity switch or a capacitive proximity switch.

[0044] Each storage area 110 is equipped with a detection module, which is used to detect the food in the storage area 110. The refrigerator also includes a controller, and the detection module and electromagnet 310 are respectively connected to the controller. The detection module detects the food storage status in the storage area 110. Based on the food storage status detected by the detection module, the controller controls the on / off state of the electromagnet 310 and the magnitude of the current flowing through the electromagnet 310.

[0045] Optionally, the detection module can be configured as a load-bearing sensor, which is used to detect the weight of the food in each storage area 110. Based on the weight of the food detected by the detection module, the controller controls the on / off state of the electromagnet 310 and the magnitude of the current flowing through the electromagnet 310, thereby adjusting the position of the first shell 212 so that the air outlet 211 is connected to one of the air inlets 111, thereby enabling centralized sterilization of the corresponding storage area 110. Of course, in other embodiments, the detection module can also be configured as a camera, which is used to detect the quantity and addition of food in each storage area 110.

[0046] In other embodiments, the electromagnet 310 can also be controlled by a voice module. The voice module is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the on / off state of the electromagnet 310 and the magnitude of the current flowing through the electromagnet 310, thereby realizing intelligent control of the sterilization sequence of multiple storage areas 110 and improving the user experience.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
