Description

Technical Field

[0001] The present application relates to the technical field of refrigerator sterilization, and in particular to an antibacterial device and a refrigerator. Background Art

[0002] Refrigerators can inhibit bacterial metabolism in low-temperature environments, allowing food to be stored for a long time without spoiling. However, in low-temperature environments, the humidity in refrigerators is high, which is very easy to breed bacteria, accelerate the spoilage of food, and produce odors, which are harmful to health. There are three main antibacterial methods. One is to add antibacterial agents to the materials and use them to inhibit bacterial metabolism on the surface of the materials; the second is to kill microorganisms through the slow release of extracts; the third is to kill microorganisms through ultraviolet lamps and ozone. However, the above antibacterial methods all have defects. For example, antibacterial agents can only act on the surface of antibacterial materials, and it is difficult to act on the surface of food, and the range of action is small; extracts such as plants or Chinese herbal medicines are mostly consumables with short lifespans, and most extracts have irritating odors; ultraviolet lamps and ozone will destroy the unsaturated bonds in polymer materials, resulting in poor material strength and yellowing of the color, and ozone and ultraviolet lamps are harmful to health.

[0003] In order to improve the antibacterial function of refrigerators, some refrigerator products utilize the antibacterial properties of probiotics and use probiotics to kill bacteria. However, the probiotics in the antibacterial devices of some refrigerators diffuse slowly. When the bacterial metabolism is strong, the bacteria cannot be killed in time, resulting in poor antibacterial effect of the refrigerator, and then poor preservation effect of food.

DETAILED DESCRIPTION

[0027] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations 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.

[0028] Refrigerators can inhibit bacterial metabolism in low-temperature environments, allowing food to be stored for a long time without spoiling. However, in low-temperature environments, refrigerators have high humidity, which can easily breed bacteria, accelerate the spoilage of food, and produce odors, which are harmful to health. In order to improve the antibacterial function of refrigerators, some refrigerator products use the antibacterial properties of probiotics to kill bacteria, but the probiotics in the antibacterial devices of some refrigerators diffuse slowly. When the bacterial metabolism is strong, the bacteria cannot be killed in time, resulting in poor antibacterial effect of the refrigerator.

[0029] In order to solve the problem of poor antibacterial effect of refrigerators, some embodiments of the present application provide an antibacterial device, see Figure 1-4 The antibacterial device includes: a cavity 3, a fan 5, a valve 6, a nozzle 10 and a controller 7.

[0030] The cavity 3 is disposed in the fresh-keeping compartment 1 of the refrigerator. In some embodiments, see Figure 5 , the cavity 3 may be a frame with a rectangular structure in a top view, and buckles are provided on both sides of the cavity 3, and the cavity 3 is snapped with the side of the fresh-keeping compartment 1 through the buckles. The cavity 3 includes a first cavity 32 and a second cavity 33. For example, a partition may be provided in the cavity 3 to divide the cavity 3 into two independent cavities, namely the first cavity 32 and the second cavity 33. The first cavity 32 and the second cavity 33 are sealed cavities, and a probiotic gel 4 is provided in the first cavity 32, and a probiotic solution is provided in the second cavity 33. It should be noted that since the probiotic gel 4 is in a solid state, in order to load the probiotic gel 4 into the first cavity 32, the top surface of the first cavity 32 should be detachably connected to the side wall of the first cavity 32.

[0031] In some embodiments, a first sealing cover may be provided at the top of the first cavity 32, and the first sealing cover is detachably connected to the side wall of the first cavity 32. The first sealing cover may be a rectangular slot structure, and buckles may be provided on both sides of the first sealing cover, and a slot may be provided on the outside of the first cavity 32 to snap the first sealing cover to the outer wall of the first cavity 32. The valve 6 is provided on the first sealing cover, and a first connecting hole is provided on the first sealing cover, and the valve 6 is detachably connected to the first sealing cover through the first connecting hole. The first connecting hole may be a threaded hole, and the valve 6 is threadedly connected to the first sealing cover through the first connecting hole. In order to maintain the sealing of the first cavity 32, for example, a sealing tape may be wound between the valve 6 and the first connecting hole, and a sealing gasket may be provided between the first sealing cover and the top of the first cavity 32. By providing the valve 6, the probiotics can be released during the storage of food by controlling the valve 6 to be opened; and the release of the probiotics can be blocked when the refrigerator stops running to reduce the waste of the probiotics.

[0032] The fan 5 is disposed in the first cavity 32, and the fan 5 is detachably connected to the first cavity 32. In some embodiments, a connecting ear 31 may be provided on the side of the first cavity 32, and the fan 5 is fixed to the connecting ear 31 by bolts, so that the fan 5 is detachably connected to the first cavity 32. The fan 5 is used for air circulation, and the air inlet side of the fan 5 should face the probiotic gel 4, so that the probiotic gel 4 in the first cavity 32 can volatilize and diffuse faster.

[0033] In some embodiments, the second cavity 33 may have the same structure as the first cavity 32, that is, the second cavity 33 is sealed by setting a sealing cover on the top of the second cavity 33, and the second cavity 33 may also be an integral structure. Since the second cavity 33 is used to hold the probiotic solution, in order to reduce the probability of leakage of the second cavity 33, the second cavity 33 in the embodiment of the present application is set as an integral structure. The spray head 10 is arranged on the top surface of the second cavity 33, and the top surface of the second cavity 33 is provided with a second connection hole, and the spray head 10 is detachably connected to the second cavity 33 through the second connection hole. For example, the second connection hole may be a threaded hole, and the spray head 10 is threadedly connected to the top surface of the second cavity 33. When there are more food stored in the fresh-keeping compartment 1, the amount of bacterial growth is large, and more probiotics are required, so that the volatilization amount of the probiotic gel 4 is insufficient to reach the amount required to inhibit bacteria. At this time, the spray head 10 can be turned on to spray the probiotic solution into the fresh-keeping compartment 1.

[0034] In order to inject the probiotic solution into the second cavity 33, a liquid inlet is also provided on the top surface of the second cavity 33, and the top of the liquid inlet is detachably connected to a second sealing cover 13 to seal the liquid inlet and facilitate the injection of the probiotic solution into the second cavity 33.

[0035] In some embodiments, the fan 5 is an electric fan, the valve 6 can be an electric valve, the nozzle 10 can be an electrically controlled nozzle, and the controller 7 is electrically connected to the fan 5, the valve 6, and the nozzle 10 respectively. The fan 5, the valve 6, and the nozzle 10 can be automatically controlled by the controller 7 without manual operation.

[0036] See again Figure 3 The antibacterial device further includes a baffle 11, which is arranged on the spray hole side of the nozzle 10, and the baffle 11 includes a connecting end 111, and the baffle 11 is detachably connected to the top surface of the first cavity 32 through the connecting end 111. The baffle 11 is an electric baffle, and the baffle 11 is electrically connected to the controller 7. The baffle 11 is automatically controlled by the controller 7. When the baffle 11 is fully extended, the baffle 11 can completely cover the spray hole of the nozzle 10, and when the baffle 11 is fully retracted, the spray hole of the nozzle 10 can be fully exposed. By setting the baffle 11, the spraying amount of the probiotic solution can be controlled to reduce the waste of the probiotic solution and extend the use time of the device.

[0037] In some embodiments, the antibacterial device further includes a spoiler 9, which is disposed in the fresh-keeping compartment 1 and is electrically connected to the controller 7. The spoiler 9 is used to improve the uniformity of the probiotic solution after spraying. Since the probiotic solution sprayed by the nozzle 10 is in the state of water mist, the spoiler 9 can be provided to make the air in the fresh-keeping compartment 1 flow, so that the sprayed probiotic solution is evenly filled in the entire fresh-keeping compartment 1.

[0038] The antibacterial device also includes a gas sensor 8, which is arranged in the fresh-keeping compartment 1 and is electrically connected to the controller 7. The gas sensor 8 is used to detect the concentration of gas produced by bacterial metabolism in the fresh-keeping compartment 1. The gas sensor 8 feeds back the detected gas concentration value to the controller 7. The controller 7 determines which antibacterial method to use according to the gas concentration value, that is, when the gas concentration value is low, only the valve 6 is opened to inhibit bacteria by diffusion. When the gas concentration value is high, while opening the valve 6, the nozzle 10 is opened to inhibit bacteria by a combination of diffusion and spraying. The controller 7 can also control the extension amount of the baffle 11 according to the gas concentration value to control the spraying amount of the nozzle 10.

[0039] Based on the above antibacterial device, some embodiments of the present application also provide a refrigerator, again referring to Figure 3-4 The refrigerator comprises: a box body, a door body, a fresh-keeping compartment 1 and the antibacterial device 2 provided in the above embodiment, the box body is hinged with the door body, and the fresh-keeping compartment 1 is arranged inside the box body. The antibacterial device 2 comprises a cavity 3, a fan 5, a valve 6, a nozzle 10 and a controller 7. The fan 5 is arranged in the cavity 3, the valve 6 and the nozzle 10 are arranged on the top surface of the cavity 3, the cavity 3 is arranged inside the fresh-keeping compartment 1, the cavity 3 is detachably connected to the side of the fresh-keeping compartment 1, and the controller 7 is arranged on the box body.

[0040] It can be seen from the above technical scheme that the present application provides an antibacterial device and a refrigerator, the device comprising: a cavity 3, a fan 5, a valve 6, a nozzle 10 and a controller 7. The cavity 3 comprises a first cavity 32 and a second cavity 33, and the first cavity 32 and the second cavity 33 are sealed cavities. The fan 5 is arranged in the first cavity 32, and a first sealing cover is arranged on the top of the first cavity 32. The valve 6 is detachably connected to the first sealing cover, and the nozzle 10 is detachably connected to the top surface of the second cavity 33. A probiotic gel 4 is arranged in the first cavity 32, and a probiotic solution is arranged in the second cavity 33; the controller 7 is electrically connected to the fan 5, the valve 6, and the nozzle 10 respectively. The opening and closing of the fan 5, the valve 6 and the nozzle 10 are controlled by the controller 7. When the gas concentration is low, only the valve 6 is opened to inhibit bacteria by diffusion. When the gas concentration is high, the nozzle 10 is opened while the valve 6 is opened, and a combination of diffusion and spraying is used to inhibit bacteria. By adjusting the release amount of probiotics, bacteria can be effectively killed, solving the problem of poor antibacterial effect of the refrigerator. While improving the preservation effect of food, the use of probiotics can also be saved.
