Description

Technical Field

[0001] The present application relates to the technical field of disinfection and sterilization, for example, to a bacteria detection device and a refrigerator. Background Art

[0002] Refrigerators are commonly used to store various ingredients to slow their spoilage. However, because ingredients are rich in nutrients, they act as natural bacterial cultures. Even at low temperatures, bacteria can still thrive. If an ingredient spoils, bacteria can grow in large numbers. These bacteria can remain in the refrigerator and spread to other ingredients, affecting their shelf life.

[0003] At present, in order to determine whether there is a high bacterial content in the refrigerator, users will judge the bacterial content in the refrigerator by smelling whether there is any peculiar smell in the refrigerator. When the peculiar smell in the refrigerator is strong, users will turn on the sterilization function of the refrigerator or manually clean the refrigerator.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] When some food with a strong odor is stored in the refrigerator, there will be a strong odor in the refrigerator even if the bacteria content in the refrigerator is not high; this causes the user to judge the bacteria content in the refrigerator based on experience by smelling whether there is any peculiar smell in the refrigerator, which leads to a high error rate in the judgment, and the user cannot intuitively and accurately know the bacteria content in the refrigerator.

[0009] In some embodiments, the refrigerator includes the above-mentioned bacteria detection device.

[0010] The bacteria detection device and refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects:

[0011] An air pump draws ambient air into the housing of the bacteria detection device through the air inlet, allowing the air to fully contact the test strip. The color change of the test strip is used to determine the bacterial content in the air drawn into the housing, thereby determining the bacterial content of the environment in which the bacteria detection device is located.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0029] Combine Figure 1-5 As shown, an embodiment of the present disclosure provides a bacteria detection device, including a shell 10, an air pump 20 and a detection test paper 30, the shell 10 includes an air inlet 11; the air pump 20 is arranged in the shell 10, and is configured to drive gas into the shell 10 from the air inlet 11; the detection test paper 30 is arranged in the shell 10, and is configured to change color according to the bacterial content in the gas.

[0030] The bacteria detection device provided by the embodiments of the present disclosure can use an air pump 20 to draw ambient air into the housing 10 of the bacteria detection device through the air inlet 11, allowing the air to fully contact the test strip 30. The color change of the test strip 30 can be used to determine the bacterial content in the air drawn into the housing 10, thereby determining the bacterial content of the environment in which the bacteria detection device is located. Thus, by installing the bacteria detection device in a refrigerator, the user can intuitively and accurately determine the bacterial content in the refrigerator.

[0031] In this article, the bacteria detection device can be applied to household appliances, cabinets, rooms, etc. with storage space, without specific limitation. The embodiment of this disclosure uses a refrigerator as an example. In other embodiments of this application, the bacteria detection device can also be applied to other spaces to detect the bacterial content in the space.

[0032] Optionally, there can be only one air inlet 11, and the test paper 30 is disposed between the air pump 20 and the air inlet 11. Placing the test paper 30 in the air path between the air inlet 11 and the air pump 20 can accelerate the air flow rate around the test paper 30, allowing bacteria in the air to fully contact the test paper 30, thereby shortening the detection time of the test paper 30.

[0033] Optionally, there may be multiple air inlets 11. Specifically, the housing 10 may be a rectangular parallelepiped shell surrounded by six surfaces. The multiple air inlets 11 may be respectively disposed on different surfaces of the housing 10. For example, there may be two air inlets 11, one of which is disposed on the first surface of the housing 10 and the other on the second surface of the housing 10. Here, the first surface and the second surface may be any two surfaces of the housing 10, and may be adjacent or opposite surfaces.

[0034] Alternatively, the housing 10 may be olive-shaped, with multiple air inlets 11 evenly distributed on the surface of the housing 10. Thus, the housing 10 defines an olive-shaped cavity, and the air pump 20 may be located in the center of the cavity, so that airflow evenly enters the cavity from each air inlet 11.

[0035] Optionally, the housing 10 is further provided with an air outlet 12, which is connected to the exhaust port 21 of the air pump 20 via an exhaust pipe 22. To form an airflow field from the air inlet 11 to the air pump 20 within the housing 10, the exhaust port 21 of the air pump 20 is directly connected to the exterior of the housing 10 via the exhaust pipe 22. Generally, the diameter of the exhaust pipe 22 is greater than or equal to the diameter of the air inlet 11 of the housing 10, so that air can flow from the air inlet 11 into the housing 10 under the drive of the air pump 20.

[0036] Optionally, the exhaust pipe 22 can be a flexible hose connecting the exhaust port 21 of the air pump 20 and the air outlet 12 of the shell 10. The part of the shell 10 through which it passes is made of flexible material and is not easily damaged by the impact of the airflow in the shell 10.

[0037] Optionally, the bacteria detection device includes a first test paper box 46 , which is configured to place unused test paper 30 ; the first test paper box 46 is provided with a paper outlet 41 , and the test paper 30 can be drawn out from the paper outlet 41 into the housing 10 .

[0038] Optionally, the bacteria detection device includes a second test strip box 47 , which is configured to hold the used test strips 30 ; the second test strip box 47 is provided with a paper inlet 42 , and the used test strips 30 enter the second test strip box 47 through the paper inlet 42 .

[0039] Optionally, the bacteria detection device further includes a test strip box 40 and a partition 43; the test strip box 40 includes a paper outlet 41 and a paper inlet 42; the partition 43 is disposed within the test strip box 40, dividing the test strip box 40 into a first chamber 44 and a second chamber 45; wherein the first chamber 44 is connected to the paper outlet 41 and is configured to store unused test strips 30; the second chamber 45 is connected to the paper inlet 42 and is configured to store used test strips 30. In this way, providing a single test strip box 40 can achieve separate storage of unused test strips 30 and used test strips 30, thereby improving space utilization within the housing 10.

[0040] Optionally, the test strip box 40 includes a first side panel, a second side panel and a surrounding panel; the first side panel and the second side panel are arranged opposite to each other, and the first side panel, the second side panel and the surrounding panel cooperate to enclose a storage space.

[0041] Optionally, the first side panel and the second side panel are arranged in parallel, and the projections of the first side panel and the second side panel are equal in size. In this way, the enclosure is arranged perpendicular to the first side panel and / or the second enclosure, and the partition 43 can also be arranged perpendicular to the first enclosure and / or the second enclosure and intersect with the enclosure.

[0042] Optionally, the partition 43 is sealed to the inner wall of the test strip box 40. In this way, the first chamber 44 and the second chamber 45 are not connected to each other, thereby preventing bacteria carried by the used test strip 30 from contaminating the unused test strip 30.

[0043] Optionally, the first side panel and / or the second side panel are teardrop-shaped, oval-shaped, or diamond-shaped. Due to the action of the air pump 20, an airflow field is formed in the space outside the test strip box 40 and inside the housing 10. The arrangement of the panels surrounding the test strip box 40 along an arcuate surface can reduce the impact of the airflow on the test strip box 40 and avoid damage to the test strip box 40. Thus, the teardrop-shaped or streamlined surface of the test strip box 40 can reduce the resistance of the test strip box 40 to the airflow, preventing the airflow from forming vortices inside the housing 10 and causing unnecessary air pressure loss.

[0044] Optionally, the paper outlet 41 and the paper inlet 42 can both be provided on the enclosure, wherein the paper outlet 41 can be provided on the enclosure surrounding the first chamber 44 ; and the paper inlet 42 can be provided on the enclosure surrounding the second chamber 45 .

[0045] Optionally, the test strip box 40 further includes a first flexible member and a second flexible member, which are interference-fitted with each other and are configured to block the paper outlet 41 to prevent air carrying bacteria from freely entering the first chamber 44 and contaminating unused test strips 30. This allows the test strip 30 to pass only in one direction, from the first chamber 44 through the paper outlet 41 to the outside of the test strip box 40.

[0046] Optionally, the first flexible member is disposed on one side of the paper outlet 41, intersecting obliquely with the edge of the paper outlet 41. Conversely, the second flexible member is axially symmetrically disposed on the other side of the paper outlet 41. The intersection of the first and second flexible members is located on the outside of the test strip box 40. The first and second flexible members cooperate to form a sharp angle, and the test strip 30 can pass through the test strip box 40 through the sharp angle where the first and second flexible members intersect. Specifically, the first and second flexible members can be brushes.

[0047] Optionally, a partition 43 divides the storage space into a first chamber 44 and a second chamber 45. The first chamber 44 is connected to the paper outlet 41 and is configured to store unused test strips 30. The second chamber 45 is connected to the paper inlet 42 and is configured to store used test strips 30. The first chamber 44 and the second chamber 45 are not connected to each other to prevent bacteria carried by used test strips 30 from contaminating unused test strips 30.

[0048] Optionally, a first opening is provided on the enclosure, the first opening being in communication with the first chamber 44 , and the first opening is configured to add unused test strips 30 .

[0049] Optionally, the test strip box 40 further includes a first cover plate, the first cover plate covering the first opening, and the first cover plate being detachably connected to the enclosure plate. The detachable connection between the first cover plate and the enclosure plate facilitates removing the first cover plate when the test strips 30 in the first chamber 44 are exhausted, and adding test strips 30 to the first chamber 44 through the first opening.

[0050] Optionally, a rubber gasket is provided at the connection between the first cover plate and the enclosure plate. This allows the first chamber 44 to be more airtight when the first cover plate covers the enclosure plate, preventing airflow from entering the first chamber 44 along the gap between the first opening and the first cover plate and contaminating the unused test strips 30 stored in the first chamber 44.

[0051] Optionally, a second opening is provided on the enclosure, communicating with the second chamber 45 and configured to remove used test strips 30. Accordingly, the test strip box 40 further includes a second cover that covers the second opening and is detachably connected to the enclosure. This facilitates the regular removal of used test strips accumulated in the second chamber 45 and allows for regular cleaning of the second chamber 45.

[0052] Optionally, the enclosure is provided with a folded edge, the folded edge being located near the second opening, and the folded edge being provided with a cutting structure. In this way, when the test paper 30 is taken out from the second opening, the test paper 30 can be cut off by the cutting structure near the second opening.

[0053] Optionally, the cutting structure is a saw blade that intersects the enclosure obliquely and is disposed at the periphery of the second opening. Similarly, when the test paper 30 is taken out from the second opening, the test paper 30 can be cut by the saw blade at the periphery of the second opening.

[0054] Optionally, the bacteria detection device also includes a detection table 50, which is arranged on the outer wall of the test paper box 40, between the paper outlet 41 and the paper inlet 42; the test paper 30 is laid on the surface of the detection table 50, and the two ends of the test paper 30 are fixed in the test paper box 40, wherein one end is passed through the paper outlet 41 and the other end is passed through the paper inlet 42.

[0055] Optionally, the testing platform 50 includes a support portion and a platform portion. The support portion of the testing platform 50 serves to support the platform portion, thereby separating the test strip 30 from the inner wall of the housing 10 or the outer wall of the test strip box 40 to create a certain space for airflow, thereby increasing the flow rate and flow of air flowing through the surface of the test strip 30 and accelerating the detection speed of the test strip 30.

[0056] Optionally, the test strip 30 is laid on the platform portion, and the support portion connects the platform portion and the test strip box 40. There is a space between the platform portion and the test strip box 40, and the air pump 20 can be arranged in the space.

[0057] Optionally, the platform portion is provided with a plurality of through holes to improve the air permeability of the platform portion, and also to increase the contact area between the test paper and the air, thereby improving the accuracy of bacteria detection.

[0058] Optionally, the platform portion is a concave curved surface. Given equal projected areas, a curved surface has a larger surface area than a flat surface. Laying the test strip 30 on the curved platform portion allows for a larger area of the test strip 30 to be used for testing, thereby increasing the accuracy of test results. The concave platform portion prevents airflow to the test strip 30 from being diverted, while also effectively enriching bacteria carried in the airflow.

[0059] Optionally, the test station 50 is located between the paper outlet 41 and the paper inlet 42, and may also be disposed between the first test strip box 46 and the second test strip box 47. The first test strip box 46 is configured to hold unused test strips 30; the first test strip box 46 is provided with a paper outlet 41, through which the test strips 30 can be drawn into the housing 10. The second test strip box 47 is configured to hold used test strips 30; the second test strip box 47 is provided with a paper inlet 42, through which the used test strips 30 enter the second test strip box 47.

[0060] Optionally, the test paper 30 is laid on the platform portion, and the support portion connects the platform portion and the inner wall of the housing 10. There is a space between the platform portion and the inner wall of the housing 10, and the air pump 20 can be arranged in the space.

[0061] Optionally, the bacteria detection device further includes a first rotating shaft 441, which is disposed in the first chamber 44, and around which unused test strips 30 are wound. In this way, the test strips 30 can be continuously wound around the first rotating shaft 441. As the test strips 30 are used, the first rotating shaft 441 is rotated to gradually release the test strips 30.

[0062] Optionally, the inner wall of the first side panel and / or the second side panel is provided with an assembly slot, and the first rotating shaft 441 is rotatably mounted in the assembly slot. The first rotating shaft 441 is connected to the assembly slot via a bearing. The bacteria detection device also includes a first drive motor that drives the first rotating shaft 441 to rotate. This allows the first chamber 44 to automatically release the test strip, eliminating the need for the user to remove it. This improves the automation level of the bacteria detection device and makes it more convenient for users to use the bacteria detection device in a storage compartment or other space within a refrigerator.

[0063] Optionally, the bacteria detection device further includes a second rotating shaft 451, which is disposed within the second chamber 45, and around which the used test strips 30 are wound. In this manner, the test strips 30 can be continuously wound around the first rotating shaft 441. As the test strips 30 are used, the second rotating shaft 451 is rotated, gradually recovering the used test strips 30. The second rotating shaft 451 can be connected to the first rotating shaft 441 via a coupling, allowing the second rotating shaft 451 to rotate with the first rotating shaft 441.

[0064] Optionally, the inner wall of the first side panel and / or the second side panel is provided with a mounting groove, and the second rotating shaft 451 is rotatably mounted in the mounting groove. The second rotating shaft 451 is connected to the mounting groove via a bearing. The bacteria detection device also includes a second drive motor to rotate the second rotating shaft 451. The provision of the second drive motor thus allows the used test strips to be automatically recycled by the second chamber 45.

[0065] Optionally, the bacteria detection device also includes an image acquisition module 60 and a control module 70. The image acquisition module 60 is disposed in the shell 10 and is configured to obtain color information of the test paper 30; the control module 70 is electrically connected to the image acquisition module 60 and is configured to determine sterilization prompt information based on the color information.

[0066] Alternatively, the image acquisition module 60 may be disposed on the inner wall of the housing 10, and the image acquisition module 60 is disposed opposite the detection platform 50. The area where the image acquisition module 60 acquires images may be disposed on the platform portion of the detection platform 50, so that the color change of the test paper 30 can be actually acquired by the image acquisition module 60.

[0067] Optionally, the sterilization prompt information may include a suggestion to remind the user of the bacteria content in the space where the bacteria detection device is located and whether the space needs to be sterilized.

[0068] Optionally, the control module 70 is further configured to: parse the bacterial content information corresponding to the color information; and determine a sterilization prompt based on the bacterial content information. Generally, the test strip 30 includes a correspondence between the test strip's displayed color and the corresponding bacterial content in the gas. The control module 70 can match the bacterial content information of the space where the bacteria detection device is located based on the acquired color of the test strip 30 and the correspondence between the test strip's displayed color and the bacterial content, compare the bacterial content information with a preset threshold, and, based on the comparison result, push a sterilization prompt to the user.

[0069] Optionally, sterilization prompt information is determined based on the bacterial content information, including: when the bacterial content corresponding to the acquired color is greater than or equal to a preset threshold, reminding the user to sterilize the space; when the bacterial content corresponding to the acquired color is less than the preset threshold, reminding the user that the bacterial content in the space is low.

[0070] Optionally, the bacteria detection device further includes a display module 80, which is electrically connected to the control module 70 and configured to display bacterial count information and sterilization prompts. The display module 80 can be mounted on the outer wall of the housing 10. This allows the user to intuitively understand the bacterial count within the space where the bacteria detection device is located through the content displayed on the display module 80.

[0071] An embodiment of the present disclosure also provides a refrigerator comprising the bacteria detection device as described above.

[0072] The refrigerator provided by the embodiment of the present disclosure can use the air pump 20 of the bacteria detection device to suck the gas in the storage compartment into the shell 10 of the bacteria detection device through the air inlet 11, so that the gas is in full contact with the detection test paper 30, and the bacterial content in the gas sucked into the shell 10 is judged by the color change of the detection test paper 30, so that the user can intuitively and accurately know the bacterial content in the storage compartment of the refrigerator.

[0073] Optionally, the bacteria detection device is detachably connected to the inner wall of the storage compartment of the refrigerator. For example, the outer wall of the housing 10 of the bacteria detection device is provided with a suction cup, which can be adsorbed and fixed to the inner wall of the storage compartment.

[0074] Optionally, the refrigerator further includes a storage compartment, and a bacteria detection device is disposed within the storage compartment, the bacteria detection device being configured to detect the bacterial content within the storage compartment. If the bacterial content corresponding to the color of the test paper 30 obtained is greater than or equal to a preset threshold, the user is reminded to sterilize the space; if the bacterial content corresponding to the color of the test paper 30 obtained is less than the preset threshold, the user is reminded that the bacterial content in the space is low.

[0075] The disclosed embodiments further provide a refrigerator control method, comprising: obtaining color information of a test strip 30; and determining a sterilization prompt based on the color information. Optionally, determining the sterilization prompt based on the color information comprises: parsing bacterial count information corresponding to the color information; and determining the sterilization prompt based on the bacterial count information. Optionally, the refrigerator control method further comprises: pushing the bacterial count information and the sterilization prompt to a user.

[0076] The refrigerator control method provided by the disclosed embodiment can obtain color information from a test strip 30 and then determine a sterilization prompt based on the color information, enabling the bacteria detection device to automatically and regularly detect the bacterial content in the refrigerator's storage compartment and push sterilization prompts to the user. This allows the user to intuitively obtain the accurate bacterial content and sterilization recommendations within the refrigerator's storage compartment through information displayed on the display module 80, rather than relying on smell or empirical judgment.
