Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sterilization, and in particular to a sterilization and preservation bin and a refrigerator. BACKGROUND

[0002] A refrigerator reduces the internal temperature through a refrigeration system, delays the spoilage process of food, and provides a low-temperature and stable environment for users to store perishable items. In terms of food safety, some refrigerators introduce sterilization measures to reduce the impact of microorganisms on food. For example, ultraviolet sterilization, plasma ozone sterilization, photocatalytic sterilization, etc.

[0003] The ultraviolet lamp is installed at a specific position in the refrigerator, and emits ultraviolet light during operation, which can destroy the DNA structure of bacteria, viruses and other microorganisms, thereby achieving the purpose of disinfection. The effect of ultraviolet light sterilization depends on its irradiation intensity and action time, and the layout and placement of items in the refrigerator directly affect the propagation path and coverage range of ultraviolet light.

[0004] However, there are certain limitations in using ultraviolet light for sterilization. Since the ultraviolet irradiation energy decays with distance, the surface of the object close to the ultraviolet light source receives stronger energy, which may cause material aging or damage. On the contrary, the position far away from the light source receives weaker energy, which is not enough to ensure effective sterilization effect, resulting in low sterilization efficiency.

[0031] The embodiments will be described in detail below, examples of which are shown in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following embodiments do not represent all embodiments consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0032] The application of UV lamps inside the refrigerator provides means for food preservation and hygiene by destroying the DNA structure of microorganisms to achieve disinfection purposes. However, this technology has some limitations in practical application, such as the relationship between the irradiation intensity of UV light, the action time and the layout of the refrigerator and the placement of the goods.

[0033] The sterilization effect of UV light depends on its irradiation intensity and action time, and insufficient intensity or too short time may result in incomplete sterilization. The layout inside the refrigerator is complex, and the placement of goods is dense, which may block the propagation path of UV light, resulting in some areas that cannot be effectively irradiated. The shape, material and color of the goods may also affect the reflection, absorption and scattering of UV light, further affecting the sterilization effect. The UV irradiation energy decays with distance, and the surface of objects close to the UV light source receives stronger energy, which may cause material aging or damage; while the position far from the light source receives weaker energy, resulting in insufficient sterilization effect.

[0034] In some embodiments, the positions and quantities of the ultraviolet lamps can be arranged according to the layout and arrangement of the items inside the refrigerator to ensure that the ultraviolet light can cover every corner inside the refrigerator. Multiple ultraviolet lamps or adjustment of the angle and height of the ultraviolet lamps can also be considered to improve the propagation path and coverage range of the ultraviolet light. Alternatively, a smart control system can be introduced to automatically adjust the irradiation time of the ultraviolet lamps according to the temperature, humidity, and types and quantities of items inside the refrigerator to ensure optimal sterilization effect.

[0035] For example, the sterilization and preservation bin can include a drawer, a cover plate connected to the drawer, a sealed cavity formed by the drawer and the cover plate, a substrate provided on the cover plate, and an ultraviolet lamp provided on the substrate. The length of the drawer ranges from 35 to 52 cm, and the distance between the ultraviolet lamp and the bottom of the drawer ranges from 10 to 15 cm. An aluminum substrate is provided on the substrate, and the ultraviolet lamp is connected to the aluminum substrate. By forming a sealed cavity with the drawer and the cover plate and placing the ultraviolet lamp in the sealed cavity, a sterilization zone is formed. By setting the distance between the ultraviolet lamp and the bottom of the drawer, the light emitting angle of the ultraviolet lamp can irradiate every position of the drawer, thereby killing the microorganisms at the irradiated positions and improving the sterilization effect. Although the sterilization effect can be improved, there is still a problem of excessive covering of the ultraviolet lamp directly below or insufficient irradiation at the edges.

[0036] Again for example, the sterilization and preservation bin includes a control unit and a deep ultraviolet LED unit, the deep ultraviolet LED unit is movably arranged in the refrigeration chamber and electrically connected with the control unit. The degree of intelligence is high, and the distance between the deep ultraviolet LED unit and the food in the refrigeration chamber is automatically adjusted by the driving unit to ensure an appropriate sterilization distance and improve the utilization rate of ultraviolet light and the sterilization and bacteriostasis efficiency. However, to achieve the improvement of the utilization rate of ultraviolet light, the sterilization and preservation bin is configured with a distance measuring unit, a position detecting unit, and a driving unit, which is difficult to realize and has a high cost.

[0037] In summary, there are problems of insufficient irradiation or difficulty in implementation when using ultraviolet light for sterilization, resulting in low sterilization efficiency. To solve the above problems, some embodiments of the present application provide a sterilization and preservation bin, which is provided with a lampshade 300 outside the light emitting body 200, and the thickness of the lampshade 300 is different for different positions of the object, i.e. the problem of strong ultraviolet radiation energy received by the object close to the light emitting body 200 and weak ultraviolet radiation energy received by the object far from the light emitting body 200 can be solved, and the problem of uneven irradiation can also be solved.

[0038] For example, Figures 1-4As shown, the sterilization and preservation bin includes a preservation bin 100, which can be a closed or semi-closed area, such as a drawer, a functional area, etc. For example, the preservation bin 100 can be arranged in a refrigeration device, such as a refrigerator, and can be arranged in a refrigeration compartment as a fruit storage area, etc. The preservation bin 100 is used to provide a controlled environment, which can adjust temperature, humidity, light, etc. to slow down the aging and decay process of the goods.

[0039] The preservation bin 100 can have a rectangular structure. In this embodiment, the preservation bin 100 has a rectangular structure, including two side walls, a top plate, and a bottom plate. The illuminator 200 can be arranged on the side wall or the top plate.

[0040] The preservation bin 100 is internally provided with an illuminator 200, which is an object capable of emitting light. In this embodiment, the illuminator 200 is a light source for generating ultraviolet (UV) light. An ultraviolet lamp tube or other types of UV LED can be used as the illuminator 200, which can emit ultraviolet light by exciting a gas, such as mercury vapor or a semiconductor material, by electrical energy.

[0041] The illuminator 200 includes a power supply, a lamp holder, and a UV lamp tube or LED chip, etc. In the preservation bin 100, the illuminator 200 is used to release ultraviolet light to disinfect and sterilize the surface of the goods stored in the preservation bin 100.

[0042] The illuminator 200 is covered with a lampshade 300, which is a device for covering and protecting the illuminator 200, and can also guide and diffuse light, and is also used to uniformly distribute ultraviolet light and reduce energy attenuation problems caused by distance.

[0043] The lampshade 300 includes a lampshade body, which has a U-shaped cross-sectional shape. The lampshade body includes a first end 310 and a second end 320. In the first direction, the thickness of the first end 310 is less than the thickness of the second end 320. That is, for objects at different positions, to solve the problem of excessive covering of the ultraviolet lamp directly below or insufficient irradiation at the edge, different thicknesses are arranged at different positions, so that the irradiation energy received by each position in the preservation bin 100 is the same, to improve the sterilization efficiency.

[0044] The thickness of the first end 310 and the second end 320 can be set according to the vertical distance of the illuminator 200 from the bottom surface of the preservation bin 100. For example, the vertical distance of the illuminator 200 from the bottom surface of the preservation bin 100 is 20 cm, the thickness of the first end 310 can be 1 mm, and the thickness of the second end 320 can be 3 mm. The ratio of the thickness of the first end 310 to the thickness of the second end 320 can be a predetermined ratio, such as 1:3.

[0045] The first end 310 is farther from the fresh-keeping chamber 100 than the second end 320, so for objects at close range, the first end 310, being thin and far from the inner wall of the fresh-keeping chamber 100, allows more UV light to directly penetrate the nearby area, but not so strong as to cause material damage.

[0046] For objects at a distance, the second end 320 is relatively thick and close to the inner wall of the fresh-keeping chamber 100, which helps to reflect and scatter UV light, ensuring that sufficient sterilization energy is received even at a distance.

[0047] In some embodiments, the light emitter 200 is an ultraviolet lamp, which is a light source for producing ultraviolet radiation, including components such as quartz glass tubes, electrodes, ballasts (for fluorescent lamps), starters, etc. As a sterilization light source inside the fresh-keeping chamber 100, the ultraviolet lamp can destroy the DNA structure of microorganisms, thereby achieving the purpose of disinfection.

[0048] The material of the lampshade 300 can be selected according to the intensity of the light emitter 200. For low-intensity UV light sources, materials with high light transmittance can be used, such as transparent or translucent polymethyl methacrylate (PMMA), polycarbonate (PC), and other plastic materials. These materials have good mechanical strength, chemical resistance, and moderate UV transmittance, and are low in cost and easy to process, effectively transmitting UV light while providing basic physical protection.

[0049] When the intensity of the UV light source increases, quartz glass or specially coated glass can be used as the material of the lampshade 300. Quartz glass has high transmittance for UV light and remains stable at high temperatures. Special coated glass can enhance the UV transmittance of specific wavebands through coating technology, while reducing unnecessary visible light and radiation of other wavelengths, not only improving the transmission efficiency of UV light, but also optimizing the sterilization effect and reducing energy waste.

[0050] High-intensity UV light sources are lamps that generate a large amount of heat and high-energy UV radiation, and should use optical-grade quartz glass or metal-ceramic composite materials with a reflective layer as the material of the lampshade 300. Optical-grade quartz glass can maintain extremely high UV transmittance under extreme conditions and has excellent heat resistance, while metal-ceramic composite materials with a reflective layer can reflect excess heat while allowing UV light to pass through, improving overall safety and energy utilization, helping to maintain efficient sterilization.

[0051] It can be understood that if the UV light source has an adjustable light intensity, a smart material with adaptive properties can be selected, such as a photochromic material, which can automatically adjust its light transmittance according to the UV intensity, thereby achieving dynamic balance, improving the sterilization effect while avoiding excessive irradiation.

[0052] The intensity of the light from the UV lamp through the first end 310 is greater than the intensity of the light from the UV lamp through the second end 320. For example, there is a point A on the lampshade 300, and the thickness of the lampshade 300 at the point A is h. When the UV lamp is working, the UV light needs to pass through the lampshade 300 with a thickness of h at the point A and then propagate in the air for a distance H to reach the surface of the object to be sterilized. A portion of the energy Q is lost during the propagation of the UV light in the lampshade 300 罩 and a portion of the energy Q is lost during the propagation in the air 气 .

[0053] The thickness h of the lampshade 300 is designed according to the distance H of the propagation of the UV light in the air, so that Q 罩 + Q 气 is a constant value, that is, the UV energy reaching the surface of the object to be sterilized is constant, and uniform illumination of the area of the preservation bin 100 by the UV light is achieved. Further, if the loss rate of the UV light in the lampshade 300 is R 罩 and the loss rate of the UV light in the air is R 气 , then R 罩 × h + R 气 × H is a constant value.

[0054] Because the light emitter 200 is arranged on the side wall or the top plate of the preservation bin 100, in some embodiments, if the light emitter 200 is arranged on the side wall, the number of the first ends 310 of the lampshade 300 is one, and if the light emitter 200 is arranged on the top plate, the number of the first ends 310 of the lampshade 300 is two.

[0055] When the light emitter 200 is arranged on the side wall, the first end 310 of the lampshade 300 is away from the bottom plate of the preservation bin 100. It can be understood that because the first end 310 needs to irradiate a relatively far object, when arranged on the side wall, only the positions placed close to the side wall and the bottom plate connected with the side wall need a relatively weak irradiation intensity, that is, irradiated through the second end 320 with a relatively thick thickness. Therefore, the number of the first ends 310 is one.

[0056] When the light emitter 200 is arranged on the top plate, if the light emitter 200 is placed in the middle, the objects arranged below the light emitter 200 need a relatively weak irradiation intensity, and the other parts need a gradually increasing irradiation intensity. Therefore, one end of the lampshade 300 close to the bottom plate of the preservation bin 100 is the second end 320, and the thickness of the lampshade 300 gradually thins from the second end 320 to both sides until the two ends connected with the top plate are the two first ends 310.

[0057] In some embodiments, the two first ends 310 have the same thickness, which can help ensure that the light rays emitted from the light-emitting body 200 are uniformly distributed and reflected inside the lampshade 300, and the cross-sectional shape of the lampshade body formed by the two first ends 310 and the second end 320 is U-shaped, which can help guide the light rays in a specific direction while reducing scattering and wasting of the light rays.

[0058] It can be understood that in the fresh-keeping bin 100, a plurality of dispersed ultraviolet light sources can also be used to ensure that each position can uniformly receive sterilization light, avoiding the problem of energy attenuation caused by distance. Alternatively, a combination scheme of different waveband ultraviolet light sources (such as UVA, UVB, and UVC) can be used to enhance the sterilization effect, while the damage to the material is evaluated and controlled.

[0059] In some embodiments, the lampshade body further has a lampshade inner layer, which is a concave or polyhedral structure, and a plurality of light transmission holes are arranged on the lampshade inner layer. The lampshade body is used to scatter and reflect light, and the inner layer is made of a material that can transmit ultraviolet light. Through the combination of different layers, the propagation and distribution of light can be optimized.

[0060] The shape of each layer can be concave-convex design to form a reflecting surface, so that the ultraviolet light is repeatedly reflected inside to better cover the entire fresh-keeping bin 100 or the sterilized object. In addition, the lampshade inner layer is designed as a concave-convex surface, for example, a corrugated surface, so that when the light encounters these irregular surfaces, it can be reflected at different angles, and the scattering of light can be increased, which not only improves the utilization rate of light, but also makes the light more evenly distributed to every corner. The concave shape can effectively concentrate light and radiate it outward.

[0061] The inner layer can be made of a material with high reflectivity, such as mirror aluminum or a glossy coating, to ensure that as much light as possible is reflected and emitted outward.

[0062] Alternatively, it can also be in the shape of a polyhedron, and each face of the polyhedron can be designed at different angles to reflect light at different angles and achieve uniform distribution of light.

[0063] In some embodiments, an optical lens can be embedded in the lampshade body or the lampshade inner layer, which is similar to a focal length lens used for lighting, focusing or scattering light of different wavebands. By adjusting the shape and material of the lens, the ultraviolet light can be more effectively covered in a larger area, thereby improving the sterilization effect.

[0064] To achieve better uniform distribution, in some embodiments, a specific scattering material can be applied to the inside of the lampshade 300 to scatter the incident light, thereby improving the uniformity of the overall illumination. The granularity and shape of the scattering material can be designed in different forms to achieve the best uniform distribution effect.

[0065] An isolation layer can be provided between the lampshade body and the inner layer of the lampshade, which can be used to reduce heat transfer between the inner and outer light layers, protect the light source, and also affect the reflection and diffusion of light. To further increase the softness of the light, a plurality of light transmission holes are provided on the inner layer of the lampshade.

[0066] To further improve the sterilization efficiency, in some embodiments, a sliding rail and a reflection plate are provided in the lampshade body, the reflection plate is in sliding connection with the sliding rail, a rotating shaft is provided on the reflection plate, a handle is provided outside the lampshade body, the handle is connected with the sliding rail through a first connecting rod, a knob is provided outside the lampshade body, and the knob is connected with the rotating shaft through a second connecting rod.

[0067] The reflection plate can be made of high-reflectivity material to ensure effective reflection of light. The reflection plate can be rectangular or trapezoidal, and the specific shape is determined according to the U-shaped cross section of the lampshade 300. The thickness of the reflection plate can be selected according to actual needs, for example, between 1-3mm.

[0068] The sliding rail is installed on the inner wall of the lampshade 300, allowing the reflection plate to move in a specific direction, such as horizontally or vertically. The sliding rail can be a linear sliding rail or a ball sliding rail, ensuring smooth and stable movement of the reflection plate.

[0069] The rotating shaft allows the reflection plate to rotate around the axis, adjusting the reflection angle. The rotating shaft can be a spherical joint or a universal joint. The reflection plate is fixed by magnetic attraction, i.e., a magnet and a metal sheet.

[0070] The user can push the reflection plate to move on the sliding rail through the handle, adjusting the position of the reflection plate. The user can also rotate the rotating shaft on the reflection plate through the knob, adjusting the angle of the reflection plate.

[0071] Based on the above-mentioned sterilization and preservation warehouse, some embodiments of the present application also provide a refrigerator, which comprises a cabinet, the cabinet comprising a refrigeration compartment, and a sterilization and preservation warehouse provided in the refrigeration compartment.

[0072] As shown in Figure 5 , Figure 6 In some embodiments, the cabinet comprises a plurality of partitions, and the illuminator 200 can also be provided on the partitions. The preservation warehouse 100 is connected with the partitions to form a sealed or semi-sealed area.

[0073] The refrigerator provided by the embodiments of the present application is a refrigeration device, and at least includes a refrigeration system, a cooling system, a control system and a cabinet to realize refrigeration and operation. The refrigeration system is used to generate refrigeration effect, the cooling system is used to maintain a low-temperature environment, the control system is used to control the temperature and humidity in the refrigerator, and the cabinet is used to provide a storage space. It can be understood that the refrigeration system, the cooling system and the control system include specific components that can realize the above functions.

[0074] In some embodiments, the refrigeration system includes a compressor, a condenser, an evaporator and a throttling device. The compressor is used to compress refrigerant gas to increase pressure and temperature, thereby driving the refrigerant to flow in the system. During the compression process, the refrigerant changes from low-pressure high-temperature gas to high-pressure high-temperature gas, thereby generating refrigeration effect. The condenser is used to cool the high-temperature high-pressure gas discharged by the compressor into liquid state. The refrigerant gas is converted into liquid state by releasing heat through the heat sink, and is ready for the next step of the refrigeration cycle. The evaporator is used to absorb heat in the refrigeration system. The refrigerant evaporates from liquid state to gas state in the evaporator, absorbs heat from the surrounding environment, thereby achieving the purpose of reducing the temperature inside the refrigerator. The throttling device can include an expansion valve and a capillary tube, which is used to adjust the flow of refrigerant, reduce its pressure, and make it into a low-temperature low-pressure gas-liquid mixed state, ready for entering the evaporator.

[0075] In some embodiments, the cooling system includes a fan connected to the evaporator. The fan circulates air in the compartments, such as the freezer compartment and the refrigerator compartment, transfers heat to the evaporator, and helps maintain a low-temperature environment inside the refrigerator.

[0076] It should be noted that the above examples are only a simple division of the functions of the refrigerator, and do not limit the specific structure of the refrigerator in the embodiments of the present application.
