Description

Technical Field

[0001] The present invention belongs to the field of disinfection and sterilization, and in particular relates to a control method of a sterilizer and a sterilizer. Background Art

[0002] As living standards improve, more people are becoming increasingly concerned about food hygiene. This necessitates disinfection and sterilization of daily necessities and other items. For example, after cleaning kitchen utensils like cutting boards and knives, residual water stains, combined with the humid environment of the kitchen, can lead to bacterial growth and, in severe cases, mold. Consequently, sterilizers for knives, cutting boards, and other kitchen utensils, as well as other small sterilizers, have emerged.

[0003] Existing common knife and cutting board kitchenware sterilizers or other small sterilizers generally use ultraviolet lamp beads or tubular lights to irradiate and sterilize the contents at a fixed position. Ultraviolet rays of appropriate wavelengths can destroy the molecular structure of DNA or RNA in microbial cells, causing growth cell death and regenerative cell death, achieving the effect of sterilization.

[0004] However, when sterilizing objects, there are inevitably blind spots due to interference or other factors, preventing full illumination sterilization. Existing products employ methods such as internal reflective film and increased UV lamp length, but these improvements are minimal and fail to fundamentally address the blind spot issue. How can we improve sterilization efficiency in this situation? Summary of the Invention

[0005] The present invention provides a control method for a sterilizer and a sterilizer to solve the technical problem of blind spots in ultraviolet disinfection mentioned in the background art.

[0015] Furthermore, the connection line between the ultraviolet light source and the ultraviolet sensor is always arranged perpendicular to the object to be sterilized, so as to determine whether the ultraviolet light source is irradiated perpendicularly to the object to be sterilized.

[0016] Furthermore, obtaining the effective sterilization stroke in the initial movement includes:

[0017] Record the location where the UV sensor signal is interrupted;

[0018] The effective sterilization process is determined based on the endpoint of the UV sensor signal interruption position.

[0019] Furthermore, the sterilizer further includes a movable ultraviolet auxiliary light source, the ultraviolet auxiliary light source is located on a side of the object to be sterilized away from the ultraviolet light source, and the ultraviolet sensor moves synchronously with the ultraviolet light source; the method further includes:

[0020] According to the ultraviolet irradiation condition of the object to be sterilized, the ultraviolet auxiliary light source is controlled to irradiate the back side of the object to be sterilized.

[0021] Furthermore, the method of controlling the ultraviolet auxiliary light source to irradiate the back of the object to be sterilized according to the ultraviolet irradiation condition of the object to be sterilized includes:

[0022] When the ultraviolet light source irradiates the front of the object to be sterilized, the ultraviolet auxiliary light source is controlled to irradiate the back of the object to be sterilized;

[0023] When the ultraviolet light source irradiates the outside of the front of the object to be sterilized, the ultraviolet auxiliary light source is controlled to be turned off.

[0024] A sterilizing machine, comprising:

[0025] Movable UV light source;

[0026] A first control module controls the initial movement of the ultraviolet light source;

[0027] An identification module is used to identify the ultraviolet irradiation status of the object to be sterilized during the initial movement of the ultraviolet light source;

[0028] An acquisition module, used to obtain an effective sterilization stroke in the initial movement according to the ultraviolet irradiation condition of the object to be sterilized;

[0029] The second control unit is used to control the reciprocating motion of the ultraviolet light source in an effective sterilization stroke to sterilize the object to be sterilized.

[0030] Furthermore, the sterilizer further comprises a movable ultraviolet sensor, which is located on a side of the object to be sterilized away from the ultraviolet light source, and the ultraviolet sensor moves synchronously with the ultraviolet light source to receive the light emitted by the ultraviolet light source;

[0031] The identification module is used to determine that the ultraviolet light source is irradiating the object to be sterilized when the ultraviolet sensor receives the light of the ultraviolet light source, and to determine that the ultraviolet light source is irradiating outside the object to be sterilized when the ultraviolet sensor signal is interrupted.

Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Those skilled in the art will appreciate that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0054] Figure 1 The flow chart of one embodiment of the control method of the sterilizing machine is schematically shown. Figure 1 As shown, the embodiment of the present application proposes a control method for a sterilizer. The sterilizer includes a movable ultraviolet light source 5. The control method for the sterilizer includes the following steps:

[0055] S10, controlling the ultraviolet light source 5 to move initially;

[0056] The initial movement of the ultraviolet light source 5 is generally controlled to move along the length or width of the object to be sterilized to complete the entire stroke of the ultraviolet light source 5. This initial movement can be one forward movement, one forward and reverse movement, or even multiple forward and reverse movements until an effective sterilization stroke is achieved.

[0057] S20, identifying the ultraviolet irradiation condition of the object to be sterilized;

[0058] The ultraviolet irradiation condition of the object to be sterilized refers to whether the ultraviolet rays are irradiating the object to be sterilized.

[0059] Preferably, identifying the ultraviolet irradiation condition of the object to be sterilized is to identify whether the ultraviolet light source 5 is irradiating the object to be sterilized vertically.

[0060] Since the surface area of bacteria is fixed, while the irradiance varies with angle θ, the sterilization effect varies for different irradiation angles θ. Assuming the power of the UV beam is Q, the irradiance I on a surface S is calculated as follows: I = Q / S1. For the beam's cross-sectional area S, S1 = S / cosθ. Therefore, I = Q × cosθ / S. Therefore, near-vertical irradiation achieves optimal irradiation intensity. Similarly, determining whether the UV light source 5 is irradiating the object perpendicularly can achieve optimal irradiation intensity.

[0061] S30, obtaining an effective sterilization stroke in the initial movement according to the ultraviolet irradiation condition of the object to be sterilized;

[0062] The effective sterilization stroke refers to the portion of the UV light source 5's travel that corresponds to the sterilized object. When the UV light source 5 is in the effective sterilization stroke, the UV light source 5's light can effectively irradiate the sterilized object, effectively sterilizing the object. Conversely, when the UV light source 5 is not in the effective sterilization stroke, the UV light source 5's light irradiates outside the sterilized object, failing to effectively sterilize it.

[0063] A better radiation intensity can be obtained by combining vertical irradiation on the object to be sterilized. Therefore, it is preferred that the ultraviolet light source 5 irradiates the object to be sterilized vertically during the effective sterilization process.

[0064] S40, controlling the ultraviolet light source 5 to reciprocate in an effective sterilization stroke to sterilize the object to be sterilized.

[0065] Since only the effective sterilization stroke can sterilize the object to be sterilized, the object can be sterilized by moving only within the effective sterilization stroke. This eliminates unnecessary strokes and ensures that the position of the ultraviolet light source 5 is continuously changed to achieve irradiation in different directions, greatly improving the average radiation intensity of the internal sterilization ultraviolet light.

[0066] In one embodiment of the present invention, the sterilizer further comprises a movable ultraviolet sensor 6, which is located on the side of the object to be sterilized away from the ultraviolet light source 5. The ultraviolet sensor 6 moves synchronously with the ultraviolet light source 5 and is used to receive the light emitted by the ultraviolet light source 5.

[0067] Identify the UV exposure status of the items to be sterilized, including:

[0068] When the ultraviolet sensor 6 receives the light from the ultraviolet light source 5, it determines that the ultraviolet light source 5 is irradiating the object to be sterilized;

[0069] When the signal from the ultraviolet sensor 6 is interrupted, it is determined that the ultraviolet light source 5 is irradiating outside the object to be sterilized.

[0070] Furthermore, the line connecting the UV light source 5 and the UV sensor 6 is always perpendicular to the object to be sterilized, so it can be determined whether the UV light source 5 is irradiating the object vertically. This further reduces the travel of the UV light source 5, increases the average light intensity, and ensures the sterilization effect.

[0071] Accordingly, obtaining the effective sterilization process in the initial movement includes:

[0072] Record the signal interruption position of the UV sensor 6;

[0073] The effective sterilization stroke is determined according to the endpoint of the signal interruption position of the ultraviolet sensor 6.

[0074] Depending on the sensor installed on the sterilizer, the position where the UV sensor 6 signal is interrupted can be obtained directly or indirectly. For example, if a position sensor is directly installed, the position signal can be directly recorded; while if only a timer is installed, the motor speed must be maintained and the position where the UV sensor 6 signal is interrupted can be obtained indirectly through the time period.

[0075] In another embodiment of the present invention, the sterilizer further comprises a movable ultraviolet auxiliary light source 7, the ultraviolet auxiliary light source 7 is located on the side of the object to be sterilized away from the ultraviolet light source 5, and the ultraviolet sensor 6 moves synchronously with the ultraviolet light source 5;

[0076] The method further includes:

[0077] According to the ultraviolet irradiation condition of the object to be sterilized, the ultraviolet auxiliary light source 7 is controlled to irradiate the back side of the object to be sterilized.

[0078] Furthermore, according to the ultraviolet irradiation condition of the object to be sterilized, the ultraviolet auxiliary light source 7 is controlled to irradiate the back side of the object to be sterilized, including:

[0079] When the ultraviolet light source 5 irradiates the front of the object to be sterilized, the ultraviolet auxiliary light source 7 is controlled to irradiate the back of the object to be sterilized;

[0080] When the ultraviolet light source 5 irradiates the outside of the front of the object to be sterilized, the ultraviolet auxiliary light source 7 is controlled to be turned off.

[0081] Thus, both sides of the object to be sterilized can be sterilized by providing the ultraviolet light source 5. When the ultraviolet light source 5 is irradiating the object to be sterilized, the ultraviolet auxiliary light source 7 is turned off to save energy.

[0082] Specifically, the front and back surfaces of the object to be sterilized face the ultraviolet light source 5 and the ultraviolet auxiliary light source 7, respectively, so that the ultraviolet light source 5 and the ultraviolet auxiliary light source 7 move along the length of the object to be sterilized to sterilize it. In this embodiment of the present invention, the sterilizer is a knife sterilizer. The ultraviolet light source 5 and the ultraviolet auxiliary light source 7 are respectively installed in the cutting board compartment and the kitchen utensil compartment to effectively sterilize the cutting board and knife.

[0083] The sterilizer of the present application can be provided with both an ultraviolet sensor 6 and an ultraviolet light source 5 to support the processor to implement the above method. Of course, in addition to the ultraviolet sensor 6, a visual sensor or other method can also be used to detect the irradiation status of the object to be sterilized according to the situation.

[0084] In addition, the above-mentioned ultraviolet sensor 6 prevents diffusely reflected ultraviolet rays from interfering with the detection results by means of thresholds and filters, etc. This part is prior art and will not be further elaborated in this embodiment.

[0085] Figure 2 A process diagram schematically shows an embodiment of a control method for a sterilizing machine. Figure 4 The schematic diagram of the structure of the sterilizer is shown. The two chambers of the sterilizer are respectively filled with cutting boards and knives as objects to be sterilized. Figure 2 and Figure 4 As shown, the embodiment of the present application proposes a control process of the sterilizer:

[0086] First, start the ultraviolet light source 5 located on the middle partition of the sterilizer to irradiate the object to be sterilized with ultraviolet light;

[0087] At the same time, the micro-motor is started and controlled to rotate clockwise first, driving the ultraviolet light source 5 and the ultraviolet auxiliary light source 7 to move horizontally to the left along the slide rail. The horizontal movement distance is consistent with the length of the inner cavity, that is, moving from position ① to position ④ in Figure 4;

[0088] If the UV sensor 6 on the outside does not receive a signal, it means that there is an object to be sterilized in the vertical irradiation path, which means that the unilateral illumination cannot meet the sterilization requirements on the other side of the object to be sterilized, and the UV auxiliary light source 7 needs to be activated in real time for supplementary light sterilization;

[0089] At the same time, by recording the position of the object to be sterilized in the path, the specific position that needs to be focused on for sterilization can be obtained, that is, the effective sterilization stroke. By moving forward and backward once, and calculating the time twice in total, a relatively accurate effective sterilization stroke can be obtained, that is, from position ② to position ③ in the figure. The motor is controlled to reverse and rotate during the effective sterilization stroke, driving the ultraviolet light source 5 and the ultraviolet auxiliary light source 7 to move back and forth continuously. At the same time, the ultraviolet auxiliary light source 7 is turned on to supplement the light according to the signal reception situation, realizing dynamic lighting;

[0090] After running for a period of time, the motor drives the ultraviolet light source 5 and the ultraviolet auxiliary light source 7 back to the initial position, turns off the motor, turns off the ultraviolet light source 5 and the ultraviolet auxiliary light source 7, and the sterilization process ends.

[0091] like Figure 3 As shown, the present invention also discloses a sterilizing machine, comprising:

[0092] A movable ultraviolet light source 5;

[0093] The first control module 1 controls the initial movement of the ultraviolet light source 5;

[0094] Identification module 2, used to identify the ultraviolet irradiation status of the object to be sterilized during the initial movement of the ultraviolet light source 5;

[0095] An acquisition module 3 is used to obtain an effective sterilization stroke in the initial movement according to the ultraviolet irradiation condition of the object to be sterilized;

[0096] The second control unit 4 is used to control the ultraviolet light source 5 to reciprocate in an effective sterilization stroke to sterilize the object to be sterilized.

[0097] Specifically, the ultraviolet light source 5 is generally a UV lamp, while the external auxiliary light source 7 is an auxiliary UV lamp. To drive the UV lamp to slide, the sterilizer is slidably connected to a first slider via a guide rail. The first slider is fixed to a link of a first transmission chain 8. When the motor is activated, it drives the first transmission chain 8 to move, causing the UV lamp on the first slider to move.

[0098] In one embodiment of the present invention, the sterilizing machine further comprises:

[0099] A movable ultraviolet sensor 6 is located on the side of the object to be sterilized away from the ultraviolet light source 5. The ultraviolet sensor 6 moves synchronously with the ultraviolet light source 5 and is used to receive the light emitted by the ultraviolet light source 5;

[0100] The identification module 2 is used to determine that the ultraviolet light source 5 is irradiating the object to be sterilized when the ultraviolet sensor 6 receives the light from the ultraviolet light source 5, and to determine that the ultraviolet light source 5 is irradiating outside the object to be sterilized when the signal of the ultraviolet sensor 6 is interrupted.

[0101] Combine Figure 4 and Figure 5 Specifically, the sterilizer is slidably connected to a second slider via a guide rail. The two guide rails, which hold the first and second modules, are symmetrically arranged. The second slider is fixed to a link in a second transmission chain 9. When the motor is activated, it drives the second transmission chain 9, which in turn moves the UV sensor 6 on the second slider.

[0102] Furthermore, the line connecting the UV light source 5 and the UV sensor 6 is always perpendicular to the object to be sterilized. Therefore, in one embodiment of the present invention, the same motor can simultaneously drive the first and second transmission chains 8 and 9. As long as the initial positions and transmission ratios are consistent, the UV light source 5 and the UV sensor 6 can move synchronously and remain perpendicular.

[0103] Correspondingly, the acquisition module 3 is used to record the interruption position of the signal of the ultraviolet sensor 6 and determine the effective sterilization stroke according to the endpoint of the interruption position of the signal of the ultraviolet sensor 6.

[0104] In one embodiment of the present invention, the sterilizing machine further comprises:

[0105] A movable ultraviolet auxiliary light source 7, which is located on the side of the object to be sterilized away from the ultraviolet light source 5, and the ultraviolet sensor 6 moves synchronously with the ultraviolet light source 5;

[0106] The third control module is used to control the ultraviolet auxiliary light source 7 to irradiate the back side of the object to be sterilized according to the ultraviolet irradiation condition of the object to be sterilized.

[0107] Since the positions of the UV auxiliary light source 7 and the UV sensor 6 are substantially the same, the UV auxiliary light source 7 can also be installed on the second slider, thereby ensuring that the positions of the UV light source 5, the UV auxiliary light source 7 and the UV sensor 6 remain the same.

[0108] Furthermore, the third control unit controls the ultraviolet auxiliary light source 7 to irradiate the back of the object to be sterilized when the ultraviolet light source 5 irradiates the front of the object to be sterilized, and controls the ultraviolet auxiliary light source 7 to be turned off when the ultraviolet light source 5 irradiates outside the front of the object to be sterilized.

[0109] The sterilizer provided in an embodiment of the present invention includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps in the above-mentioned control method embodiments of the sterilizer are implemented, for example Figure 2 S10 to S40 shown.

[0110] For example, the computer program may be divided into one or more modules / units, which are stored in the memory and executed by the processor to implement the present invention. The one or more modules / units may be a series of computer program instruction segments capable of performing specific functions, and the instruction segments are used to describe the execution process of the computer program in the sterilizer.

[0111] The processor may be a central processing unit (CPU), or other general-purpose processors, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor, etc. The processor is the control center of the sterilizer, and uses various interfaces and lines to connect various parts of the sterilizer.

[0112] The memory can be used to store the computer programs and / or modules, and the processor realizes the various functions of the sterilizer by running or executing the computer programs and / or modules stored in the memory, and calling the data stored in the memory. The memory can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory can include a high-speed random access memory, and can also include a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (FlashCard), at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0113] In addition, the sterilizer can also be equipped with a drying device. Since the relative humidity of the ambient air has a huge impact on the inactivation rate of microorganisms, it is ideal to install a UV disinfection device in an environment with a relative humidity below 60%. Therefore, a control scheme is adopted to run the drying first and then start the UV sterilization system:

[0114] After entering the working mode, the sterilizer fan and PTC heating component are started to blow hot air into the sterilizer cavity. After a period of time (20 minutes) or when the humidity sensor detects that the humidity in the cavity reaches the set value (60%), the dynamic lighting system is started to start irradiation sterilization.

[0115] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
