Description

Technical Field

[0001] This invention relates to the field of cutting board sterilization technology, and in particular to a method and machine for controlling sterilization of knives and cutting boards. Background Technology

[0002] Knives and cutting boards are indispensable kitchen utensils in daily life. After use and washing, some moisture will remain on the utensils. In addition, the kitchen environment is usually humid and it is difficult to dry them completely under natural conditions. Bacteria can easily grow on knives and cutting boards, which can contaminate food when they come into contact with it, thus endangering human health.

[0003] In response to the practical problem that natural drying of knives and cutting boards is difficult, knife and cutting board sterilizers have become very popular in recent years, especially for square cutting boards. In terms of their working principle, the commonly used technologies on the market are: active drying by a fan and sterilization by ultraviolet light. However, since household square cutting boards come in different sizes, some larger cutting boards cannot be put into the sterilizer and require the use of the cutting board provided by the manufacturer. Alternatively, the cutting board can be put into the sterilizer, but the part that extends out of the sterilizer cavity cannot be effectively dried and sterilized. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to propose a method and machine for sterilizing and controlling the sterilization of knives and cutting boards, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is: a method for sterilizing and controlling knives and cutting boards, comprising the following steps:

[0006] Obtain the dimensions of the cutting board, and select a sterilization method to sterilize the cutting board according to the dimensions;

[0007] When the cutting board is rotated using the selected sterilization method, the system determines whether there is a cutting board rotation malfunction based on the sensing information of the cutting board rotation, and outputs a control signal to determine whether the cutting board has completed rotation based on the determination result.

[0008] As a further improvement of the present invention: in the step of selecting the sterilization method according to the size of the cutting board...

[0009] The cutting board sizes include small size, large size on one side, and large size on both sides;

[0010] The sterilization methods include a conventional mode corresponding to small sizes, a single-rotation mode corresponding to large sizes on one side, and a multi-rotation mode corresponding to large sizes on both sides.

[0011] As a further improvement of the present invention: the step of obtaining the cutting board size includes:

[0012] When the length of the long side of the cutting board A is less than or equal to the length of the long side of the cutting board groove of the sterilizer A0 + l, and the length of the short side of the cutting board B is less than or equal to the length of the short side of the cutting board groove of the sterilizer B0 + l, the cutting board is judged to be of small size.

[0013] If the length of the long side of the cutting board A is greater than the length of the long side of the cutting board groove of the sterilizer A0+l, and the length of the short side of the cutting board B is less than or equal to the length of the short side of the cutting board groove of the sterilizer B0+l, the cutting board is determined to be a single-sided large size.

[0014] If the length of the long side of the cutting board A is less than or equal to the length of the long side of the cutting board groove of the sterilizer A0+l, and the length of the short side of the cutting board B is greater than or equal to the length of the short side of the cutting board groove of the sterilizer B0+l, then the cutting board is determined to be a single-sided large size.

[0015] If the length of the long side of the cutting board A is greater than the length of the long side of the cutting board groove of the sterilizer A0+l, and the length of the short side of the cutting board B is greater than the length of the short side of the cutting board groove of the sterilizer B0+l, then the cutting board is determined to be a double-sided large size.

[0016] As a further improvement of the present invention: the conventional mode includes: the sterilizer starts the fan, heating element and ultraviolet lamp, and after the drying and sterilization time T0, the sterilizer is turned off after the cutting board is sterilized.

[0017] As a further improvement of the present invention: the single-rotation mode includes: the sterilizer starts the fan, heating element and ultraviolet lamp, after the drying and sterilization time a*T0, the rotating motor controls the rotating frame and the transmission motor controls the transmission belt to make the cutting board rotate 2*90° and to sense the rotation of the cutting board. After the rotation is completed, after the drying and sterilization time b*T0, the cutting board is sterilized, the rotating motor is reset and the sterilizer is turned off. Here, a and b are adjustment coefficients, and 0≤a≤100% and 0≤b≤100%.

[0018] As a further improvement of the present invention: the dual-rotation mode includes: the sterilizer starts the fan, heating element and ultraviolet lamp. After the drying and sterilization time c*T0, the rotating motor controls the rotating frame and the transmission motor controls the transmission belt to make the cutting board rotate 90° and to sense the rotation of the cutting board. After the drying and sterilization time d*T0, the cutting board is controlled to rotate 90° and to sense the rotation of the cutting board. After the drying and sterilization time e*T0, the cutting board is controlled to rotate 90° and to sense the rotation of the cutting board. After the drying and sterilization time f*T0, the cutting board is sterilized, the rotating motor is reset and the sterilizer is turned off. Here, c, d, e and f are adjustment coefficients, and 0≤c≤100%, 0≤d≤100%, 0≤e≤100%, 0≤f≤100%.

[0019] As a further improvement of the present invention: the step of determining whether there is a cutting board rotation fault based on the sensing information of the cutting board rotation includes: the rotating motor rotates 90° to drive the rotating frame to rotate, the rotating frame switches from a horizontal state to a vertical state, after waiting for a time T1, it is determined whether the sensor senses a rotation completion signal. If the sensor senses a rotation completion signal, it is determined that the cutting board has completed a 90° rotation, and the rotating motor is reset to the horizontal position. If the sensor does not sense a rotation completion signal, it is determined that the cutting board has not completed a 90° rotation, and the transmission mode is entered.

[0020] As a further improvement of the present invention: the transmission mode includes: the transmission motor rotates to drive the transmission belt to make the cutting board move horizontally, and it is determined whether the sensor senses the rotation completion signal. If the sensor senses the rotation completion signal, it is determined that the cutting board has completed a 90° rotation, and the transmission motor is reset to the horizontal position. If the sensor does not sense the rotation completion signal, it is detected whether the working time of the transmission motor exceeds T2.

[0021] If the drive motor exceeds T2, it is determined that the cutting board has not completed a 90° rotation and is stuck in the middle position. The drive motor stops, the rotation motor rotates 90° in the opposite direction, and the rotating frame rotates to the horizontal position. It is then determined whether the sensor has detected a rotation completion signal. If the sensor has detected a rotation completion signal, it is determined that the cutting board has completed a 90° rotation. If the sensor has not detected a rotation completion signal, it is determined that the cutting board has not completed a 90° rotation and is stuck in the middle position, and the secondary drive mode is entered.

[0022] If not, the drive motor rotates, driving the drive belt.

[0023] As a further improvement of the present invention: In the secondary transmission mode, the transmission motor rotates to drive the transmission belt so that the anvil continues to move horizontally. It is determined whether the sensor detects a rotation completion signal. If the sensor detects a rotation completion signal, it is determined that the anvil has completed a 90° rotation and the transmission motor stops. If the sensor does not detect a rotation completion signal, it is detected whether the working time of the transmission motor exceeds T2. If not, the transmission motor rotates to drive the transmission belt. If so, an error is reported.

[0024] Another solution provided by the present invention is a sterilization machine that applies the knife and cutting board sterilization control method described above. It also includes a housing, in which a knife slot and a double-sided open cutting board slot are provided. The housing also includes a transmission structure, a rotation structure, a sensor, and an ultraviolet lamp. The transmission structure includes a transmission motor and a transmission belt. The rotation structure includes a rotation motor and a rotating frame. The rotation motor is connected to one end of the rotating frame to drive the rotating frame to rotate. The housing also includes side rollers, a fan, and a heating element.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention adopts a double-sided open cutting board groove, which rotates the cutting board through a rotating structure and is coordinated with a transmission structure to ensure smooth rotation of the cutting board. This allows all parts of a large cutting board to be effectively dried and sterilized, solving the problem that the part of the cutting board that is too large to be dried and sterilized beyond the sterilization machine.

[0027] 2. The box of this invention also uses side rollers, which can prevent the cutting board from being unable to rotate due to excessive friction on the side. Combined with the transmission structure and the rotation structure, the rotation of the cutting board can be reduced by reducing rotation obstacles, so as to achieve smooth rotation of the cutting board.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0041] Because current knife and cutting board sterilizers generally only open the top slot, if the cutting board is too large, it cannot be inserted into the slot. Even if the cutting board is too large to fit, it will not be able to be dried and sterilized if it exceeds the size of the sterilizer.

[0042] The present invention will now be further described in conjunction with the accompanying drawings and embodiments: Embodiments of the present invention provide a method for controlling the sterilization of knives and cutting boards, such as... Figure 1-3 As shown, it includes the following steps:

[0043] Obtain the dimensions of the cutting board, and select a sterilization method to sterilize the cutting board 14 according to the dimensions;

[0044] When the sterilization mode rotates the cutting board 14, the sensor information of the rotation of the cutting board 14 is used to determine whether there is a rotation fault of the cutting board 14, and the control signal of whether the cutting board 14 has completed rotation is output according to the judgment result.

[0045] Through the above steps, a sensor is used to obtain the size of the cutting board when the sterilizer is started. The size of the cutting board is obtained by pre-inputting multiple cutting board sizes into the sterilizer system. The sensor obtains the size data of the cutting board 14 to be sterilized, with the long side length A and the short side length B. Based on the cutting board size data, the sterilizer selects the corresponding sterilization method to sterilize the cutting board 14. The sterilizer body 1 adopts a double-sided open cutting board slot structure, which allows large cutting boards 14 to be placed smoothly. The cutting board 14 is rotated by a rotating structure, and at the same time, the transmission structure ensures that the cutting board 14 rotates smoothly, so that all parts of the large cutting board 14 can be effectively dried and sterilized, solving the problem that the part of the cutting board 14 that is too large and exceeds the sterilizer cannot be dried and sterilized.

[0046] Furthermore, in the step of selecting the sterilization method based on the size of the cutting board,

[0047] The cutting board sizes include small size, large size on one side, and large size on both sides;

[0048] The sterilization methods include a conventional mode corresponding to small sizes, a single-rotation mode corresponding to large sizes on one side, and a multi-rotation mode corresponding to large sizes on both sides.

[0049] For better understanding, in an optional embodiment, obtaining the cutting board size includes:

[0050] When the length of the long side A of the cutting board 14 is less than or equal to the length of the long side A0 + l of the cutting board groove of the sterilizer, and the length of the short side B of the cutting board 14 is less than or equal to the length of the short side B0 + l of the cutting board groove of the sterilizer, the cutting board 14 is judged to be of a small size.

[0051] When the cutting board 14 is determined to be small in size, the entire cutting board 14 is within the cutting board groove, and conventional drying can be used. The conventional mode includes: starting the sterilizer with fan 2, heating element 3, and ultraviolet lamp 4; after drying and sterilization time T0, the sterilizer is turned off after sterilizing the cutting board 14. l is the compensation amount, that is, when the length of the cutting board 14 slightly exceeds the cutting board groove, the reduction in drying effect around the cutting board 14 is negligible.

[0052] When the length of the long side A of the cutting board 14 is greater than the length of the long side A0+l of the cutting board groove of the sterilizer, and the length of the short side B of the cutting board 14 is less than or equal to the length of the short side B0+l of the cutting board groove of the sterilizer, the cutting board 14 is determined to be a single-sided large size.

[0053] If the length of the long side A of the cutting board 14 is less than or equal to the length of the long side A0+l of the cutting board groove of the sterilizer, and the length of the short side B of the cutting board 14 is greater than or equal to the length of the short side B0+l of the cutting board groove of the sterilizer, then the cutting board 14 is determined to be a single-sided large size.

[0054] When it is determined that the cutting board 14 is a single-sided large size, in addition to drying under normal conditions, the cutting board 14 needs to be rotated 180° to achieve full drying of the cutting board 14. The single rotation mode includes: the sterilizer starts the fan 2, heating element 3 and ultraviolet lamp 4. After the drying and sterilization time a*T0, the rotating motor controls the rotating frame 10 and the transmission motor 6 controls the transmission belt 7 to make the cutting board 14 rotate 2*90° and to sense the rotation of the cutting board 14. After the rotation is completed, after the drying and sterilization time b*T0, the cutting board 14 is sterilized and the rotating motor 9 is reset and the sterilizer is turned off. Here, a and b are adjustment coefficients, and 0≤a≤100% and 0≤b≤100%. After the user places the cutting board 14 as required, the drying and sterilization function is activated. After passing through a*T0, the basic drying is completed under normal conditions. The cutting board 14 rotates two 90° (i.e., 180°) and after passing through b*T0, the fan 2, heating element 3, and ultraviolet lamp 4 stop, and the rotating motor 9 returns to its initial position.

[0055] If the length of the long side A of the cutting board 14 is greater than the length of the long side A0+l of the cutting board groove of the sterilizer, and the length of the short side B of the cutting board 14 is greater than the length of the short side B0+l of the cutting board groove of the sterilizer, then the cutting board 14 is determined to be a double-sided large size.

[0056] When the cutting board 14 is determined to be a double-sided large size, it needs to be dried by rotating all four sides. The double-rotation mode includes: the sterilizer starts the fan 2, heating element 3 and ultraviolet lamp 4. After the drying and sterilization time c*T0, the rotating motor controls the rotating frame 10 and the transmission motor 6 controls the transmission belt 7 to make the cutting board 14 rotate 90° and sense the rotation of the cutting board 14. After the drying and sterilization time d*T0, the cutting board 14 is controlled to rotate 90° and sensed to rotate. After the drying and sterilization time e*T0, the cutting board 14 is controlled to rotate 90° and sensed to rotate. After the drying and sterilization time f*T0, the cutting board 14 is sterilized and the rotating motor 9 is reset and the sterilizer is turned off. Here, c, d, e and f are adjustment coefficients, and 0≤c≤100%, 0≤d≤100%, 0≤e≤100%, 0≤f≤100%. After the user places the cutting board 14 as required, the drying and sterilization function is activated. After passing c*T0, the rotation process begins. After completing a 90° rotation, drying continues. After passing d*T0, the second rotation begins. After completing a 90° rotation, drying continues. After passing e*T0, the third rotation begins. After completing a 90° rotation, drying continues. After passing f*T0, drying is complete. The heating element 3, fan 2, and UV lamp 4 are turned off, and the rotating motor 9 returns to its initial position.

[0057] To better address the issue of cutting board 14 rotation and ensure compatibility with cutting boards 14 of various sizes, a sensor 12 is used to sense the state of the cutting board. When the cutting board 14 is placed, the sensor 12 is in a sensing state. During the rotation, there will be a period of no sensing. After completing a 90° rotation, the sensing state of the sensor 12 below will switch back to sensing. Therefore, sensing-no sensing-sensing is the typical process of a 90° rotation, which is defined here as the rotation completion signal.

[0058] To better understand the solution of this embodiment, when the cutting board rotation program begins, the rotation motor 9 starts and rotates 90°, causing the rotating frame 10 to switch from a horizontal to a vertical state. After time T1, if the sensor 12 senses a rotation completion signal, it indicates that the 90° rotation has been completed. If no rotation signal is sensed, it indicates that the cutting board 14 has not completed the 90° direction switch, which may be because the cutting board is resting on the rotating frame 10.

[0059] The cutting board 14 moves horizontally. In this embodiment of the invention, there are two situations in which the cutting board 14 completes the rotation: 1. If the rotating frame 10 alone can complete the 90° rotation of the cutting board, the transmission motor 6 driven by the bottom drive conveyor belt does not need to move; 2. If the rotating frame 10 alone cannot complete the 90° rotation of the cutting board, then the transmission motor 6 needs to rotate the transmission belt 7 to drive the cutting board 14 to move, and the 90° rotation is completed by the curvature of the rotating frame 10.

[0060] In this embodiment, determining whether there is a cutting board rotation fault based on the sensing information of the cutting board rotation includes: the rotating motor 9 rotates 90° to drive the rotating frame to rotate, the rotating frame 10 switches from a horizontal state to a vertical state, and after waiting for a time T1, it is determined whether the sensor 12 senses a rotation completion signal. If the sensor 12 senses a rotation completion signal, it is determined that the cutting board has completed a 90° rotation, and the rotating motor 9 is reset to a horizontal position. If the sensor 12 does not sense a rotation completion signal, it is determined that the cutting board has not completed a 90° rotation, and the transmission mode is entered.

[0061] In this embodiment, the transmission mode includes: the transmission motor rotates to drive the transmission belt 7 to make the anvil 14 translate, and it is determined whether the sensor 12 senses the rotation completion signal. If the sensor 12 senses the rotation completion signal, it is determined that the anvil 14 has completed a 90° rotation, and the transmission motor 9 is reset to the horizontal position. If the sensor 12 does not sense the rotation completion signal, it is detected whether the working time of the transmission motor 6 exceeds T2.

[0062] If the drive motor 6 exceeds T2, it is determined that the chopping board 14 has not completed a 90° rotation and is stuck in the middle position. The drive motor 6 stops, the rotation motor 9 rotates 90° in the opposite direction, and the rotating frame 10 rotates to the horizontal position. It is then determined whether the sensor 12 has sensed the rotation completion signal. If the sensor 12 senses the rotation completion signal, it is determined that the chopping board 14 has completed a 90° rotation. If the sensor 12 does not sense the rotation completion signal, it is determined that the chopping board 14 has not completed a 90° rotation and is stuck in the middle position, and the secondary transmission mode is entered.

[0063] If not, the drive motor rotates, driving the drive belt 7.

[0064] In this embodiment, in the secondary transmission mode, the drive motor rotates to drive the drive belt 7 so that the anvil 14 continues to move horizontally. It is determined whether the sensor 12 senses a rotation completion signal. If the sensor 12 senses a rotation completion signal, it is determined that the anvil 14 has completed a 90° rotation and the drive motor 6 stops. If the sensor 12 does not sense a rotation completion signal, it is detected whether the working time of the drive motor 6 exceeds T2. If not, the drive motor rotates to drive the drive belt 7. If so, an error is reported.

[0065] To better understand the rotation process in the embodiments of the present invention:

[0066] 1. For example Figure 4 This is the initial state of the cutting board 14 when it is placed in the cutting board slot of the sterilizer.

[0067] 2. The rotating frame 10 begins to rotate (45°), as follows. Figure 5 As shown;

[0068] The rotating frame 10 rotates, lifting the right side of the cutting board 14. The cutting board 14 rotates counterclockwise inside the cutting board groove of the box 1. The lower right corner of the cutting board 14 contacts the rotating frame 10, the lower left corner contacts the transmission belt 7, and the left side contacts the upper left corner of the box 1 (arrows point to the contact points).

[0069] 3. Rotate the rotating frame 10 to the high position (85°), as follows: Figure 6 As shown;

[0070] The rotating rack 10 rotates to a high angle, and the cutting board 14 rotates counterclockwise to a greater angle.

[0071] 4. The conveyor belt moves to the right, as shown. Figure 7-8 As shown;

[0072] When the drive motor 6 rotates, the conveyor belt moves to the right, and the bottom corner of the anvil 14 contacts the drive belt 7. The friction between the two will cause the anvil 14 to continue to rotate. The arrow points to the direction of transmission.

[0073] 5. The cutting board 14 has finished rotating, as follows: Figure 9 As shown;

[0074] After rotating to a certain angle, the center of gravity of the cutting board 14 will shift to the left, and it will continue to rotate counterclockwise to complete the rotation.

[0075] The transmission mode process is as follows:

[0076] Turn on the drive motor 6 to drive the drive to roll towards the slotted side, apply power to promote the rotation of the anvil 14. If a rotation completion signal is sensed within time T2, it means that the rotation has been completed, and the drive motor 6 stops.

[0077] If sensor 12 does not detect a rotation completion signal within time T2, it means that the chopping board 14 is stuck in the middle position. At this time, the drive motor 6 stops, the rotation motor 9 rotates 90° in the opposite direction, and the rotating frame 10 rotates to the horizontal position. At this time, the chopping board 14 lacks the support of the rotating frame 10 and will roll towards the horizontal due to the center of gravity. If a rotation completion signal is detected, it means that the chopping board 14 has completed a 90° rotation.

[0078] If sensor 12 does not detect a rotation completion signal, the anvil 14 is in the middle position and the drive motor 6 rotates. If a rotation completion signal is detected within time T2, it means that the rotation has been completed, and the drive motor 6 stops. If no rotation completion signal is detected within time T2, an error is reported.

[0079] Another solution provided by the present invention, such as Figure 10-11As shown, a sterilization machine, employing the knife and cutting board sterilization control method described above, further includes a housing 1. The housing 1 is provided with a knife slot and a double-sided open cutting board slot. The housing 1 is also provided with a transmission structure, a rotation structure, a sensor 12, and an ultraviolet lamp 4. The transmission structure includes a transmission motor 6 and a transmission belt 7. The rotation structure includes a rotation motor 9 and a rotating frame 10. The rotation motor 9 is connected to one end of the rotating frame 10 to drive the rotating frame 10 to rotate. The housing 1 is also provided with side rollers 13, a fan 2, and a heating element 3.

[0080] This invention uses a double-sided open cutting board groove. The cutting board 14 is rotated by a rotating structure, and at the same time, a transmission structure is used to make the cutting board 14 rotate smoothly. This allows all parts of the large cutting board 14 to be effectively dried and sterilized, solving the problem that the part of the cutting board 14 that is too large to be dried and sterilized beyond the sterilization machine.

[0081] The sterilizer is mainly composed of the following components: housing 1, fan 2, heating element 3, ultraviolet lamp 4, air duct 5, drive motor 6, drive belt 7, drive shaft 8, rotating motor 9, rotating frame 10, water receiving tray 11, sensor 12 and side rollers 13. The housing 1 has a knife slot and a double-sided open cutting board slot.

[0082] Box 1: The main structure of the knife and cutting board sterilizer. It has a knife rack with grooves on the top for easy placement of knives, a bottom plate with drainage holes on the bottom, and open cutting board slots on both sides. The closed side of the cutting board slots has side rollers to reduce the frictional resistance when the cutting board 14 rotates. There is a transmission belt 7 on the bottom side, which allows the cutting board 14 to move laterally.

[0083] Fan 2: Forces airflow to provide the air volume required for drying.

[0084] Heating element 3: Provides the required heat so that the drying air is hot air.

[0085] Air duct 5: Guides the air from fan 2 into housing 1.

[0086] UV lamp 4: Generates ultraviolet light to kill bacteria.

[0087] Drive motor 6: provides power for the lateral movement of the cutting board 14.

[0088] 7. Drive belt and 8. Drive shaft: The transmission carrier for the transverse movement of the anvil 14.

[0089] Rotary motor 9: provides power for the rotation of rotating frame 10.

[0090] Rotating rack 10: The rotating rack 10 has a smooth curve shape and built-in rollers to reduce the rotational resistance of the cutting board 14 and guide the rotation process of the cutting board 14.

[0091] Drain tray 11: Temporarily stores water dripping from knives and cutting boards 14.

[0092] Sensor 12: Detects the distance to the cutting board 14 to determine whether it is attached to the conveyor belt.

[0093] When the cutting board 14 is relatively thin and the limiting margin on both sides of the cutting board 14 is large, the cutting board retaining rib 15 can limit it to a certain degree of inclination.

[0094] In summary, after reading this invention document, those skilled in the art can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort, and all of these modifications fall within the scope of protection of this invention.
