Description

Technical Field

[0001] This invention relates to the field of tableware oil stain detection technology, and in particular to an intelligent disinfection cabinet with photoelectric detection function for tableware surface oil stains. Background Technology

[0002] A tableware sterilizer is a cabinet used for sterilizing and disinfecting tableware. Its sterilization methods mainly include high-temperature thermal radiation sterilization and / or ultraviolet germicidal lamp sterilization. During high-temperature thermal radiation sterilization, the sterilization chamber used to place the tableware is in a high-temperature state, while ultraviolet germicidal lamp sterilization does not generate high temperatures.

[0003] Currently, tableware sterilizers are equipped with tableware racks inside the sterilization chamber. These racks are used to place tableware, which mainly includes plates, chopsticks, knives, forks, and spoons. Because chopsticks are easily deformed by heat, sterilizers are usually equipped with a separate ultraviolet sterilization chamber. This ultraviolet sterilization chamber uses ultraviolet germicidal lamps to sterilize the chopsticks. To save energy, spoons and knives are usually also placed in the ultraviolet sterilization chamber for sterilization. Plates and bowls, due to their large surface area, are usually placed in the heating sterilization chamber for high-temperature heating sterilization.

[0004] However, the above-mentioned existing technologies still have shortcomings in use: 1. Due to their large surface area, plates have residual oil stains on their outer surface after cleaning. It is difficult for people to detect oily plates by visual inspection. The residual oil stains are not easily removed by high-temperature disinfection. Oily plates will affect the appearance when used and will also contaminate food; 2. When using ultraviolet germicidal lamps to sterilize chopsticks, knives, forks and spoons, there are blind spots in the light because these utensils are stacked, which makes it difficult to completely and thoroughly disinfect them.

[0005] Therefore, this invention proposes an intelligent disinfection cabinet with photoelectric detection function for oil stains on tableware surfaces. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent disinfection cabinet with photoelectric detection function for oil stains on tableware surfaces in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A smart disinfection cabinet with photoelectric detection function for oil stains on tableware surfaces includes a cabinet body with a disinfection chamber inside. A grooved cover is fixedly connected to the outside of the cabinet body. Two rows of guide frames are fixedly connected between one side of the disinfection chamber and one side of the grooved cover. An access window that fits over the guide frames is opened on one side of the cabinet body. A row of rectangular brackets is provided on the guide frames. The rectangular brackets and guide frames are slidably connected, and adjacent rectangular brackets are movably connected by a hinged rod assembly. A slide is provided between the two rows of guide frames. The slide is provided with a positioning sleeve. A bracket is rotatably connected to the top of the positioning sleeve. A photoelectric detector is detachably connected to one side of the bracket. A sealing plate located on the outside of the cabinet body is fitted on the guide frame. One side of the sealing plate is fixedly connected to an opposite rectangular bracket through a connecting shaft.

[0008] As a further description of the above technical solution: The slide includes a limiting sleeve and a rotatable connecting sleeve located below the limiting sleeve. The limiting sleeve is fitted outside the positioning sleeve and the two are rotatably connected. A sector toothed plate is fixed at the bottom of the positioning sleeve. A transmission gear that meshes with the sector toothed plate is fixedly fitted outside the connecting sleeve. A bevel gear is fixed at the lower part of the bracket. A limiting plate that meshes with the bevel gear is fixed at the top of the limiting sleeve.

[0009] As a further description of the above technical solution: An upper rotating shaft and a lower rotating shaft are respectively provided between one side of the cabinet and one side inside the slotted cover, passing through the limiting sleeve and the connecting sleeve. The upper rotating shaft and the limiting sleeve are screwed together, and the lower rotating shaft and the connecting sleeve are axially slidably connected.

[0010] As a further description of the above technical solution: A heat insulation cover is fixed between the two sides of the disinfection chamber. One end of the heat insulation cover is connected to the outside. An upper control motor and a lower control motor are fixedly connected to one side inside the heat insulation cover. The output shafts of the upper control motor and the lower control motor are fixedly connected to one end of the upper rotating shaft and the lower rotating shaft, respectively.

[0011] As a further description of the above technical solution: A crossbeam is provided above the positioning sleeve. The middle part of the bottom of the crossbeam is fixedly connected to the top wall of the positioning sleeve through a support plate. An L-shaped baffle that is close to the outer periphery and cooperates with one end of the crossbeam is fixedly connected to the outer side of the sealing plate.

[0012] As a further description of the above technical solution: The trough-shaped cover has cabinet doors on its left and right sides. One end of each cabinet door is hinged to the cabinet body and two roller carriers are fixed inside the door. An ultraviolet germicidal lamp is fixedly connected to the cabinet door above the roller carriers.

[0013] As a further description of the above technical solution: The roller carrier includes a grooved support and a front cage-shaped cylinder and a rear cage-shaped cylinder located within the grooved support. The grooved support is fixedly connected to the inner side of the cabinet door. The open ends of the front cage-shaped cylinder and the rear cage-shaped cylinder are opposite to each other and coaxial. A front axle and a rear axle are respectively fixed to the opposite sides of the front cage-shaped cylinder and the rear cage-shaped cylinder. A guide sleeve sleeved on the outside of the front axle is rotatably connected to the grooved support. The guide sleeve is slidably connected to the front axle. The rear axle is rotatably connected to the grooved support.

[0014] As a further description of the above technical solution: An arc-shaped support plate near the bottom is provided between the front cage-type cylinder and the rear cage-type cylinder, and the bottom wall of the arc-shaped support plate is fixedly connected to the bottom of the support rod and the groove-type support.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting up a cabinet, a disinfection chamber, a guide frame, a rectangular bracket, an entrance / exit window, a hinged rod assembly, a slide, a positioning sleeve, a bracket, and a photoelectric detector, a row of plates can be moved and inspected by the photoelectric detector before being disinfected. At the same time, due to the setting of the hinged rod assembly, the row of plates can be in a large-spaced state, which allows the photoelectric detector to inspect both sides of the plates without obstruction. This not only improves the accuracy of the inspection, but also prevents oily plates from contaminating the disinfection chamber after inspection, thus ensuring the cleanliness of the plates and the disinfection chamber.

[0016] 2. In this invention, by setting up cabinet doors, roller carriers and ultraviolet germicidal lamps, strip-shaped tableware can eliminate light blind spots when it is tumbling during ultraviolet germicidal lamp sterilization, thereby enabling comprehensive sterilization of strip-shaped tableware and having the advantage of more thorough disinfection of strip-shaped tableware.

[0017] 3. In this invention, by setting a groove-shaped support, a guide sleeve and a front shaft, the distance between the front cage-shaped cylinder and the rear cage-shaped cylinder can be adjusted. This setting allows the roller carrier to support strip-shaped tableware of different specifications, thus expanding the applicable range of this disinfection cabinet. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] Please see Figure 1-7 A smart disinfection cabinet with photoelectric detection function for oil stains on tableware surface includes a cabinet body 1, a disinfection chamber 2 is provided inside the cabinet body 1, and an electric heating tube can be installed on the top wall of the disinfection chamber 2. When the electric heating tube is powered on, it generates heat radiation that can disinfect.

[0023] A grooved cover 3 is fixedly connected to the outside of the cabinet 1. Two rows of guide frames 4 are fixedly connected between one side of the disinfection chamber 2 and one side of the grooved cover 3. The guide frame 4 is composed of two guide columns. The two ends of the guide columns are fixedly connected to the opposite side walls of the disinfection chamber 2 and the grooved cover 3, respectively. An entrance and exit window 5 is opened on one side of the cabinet 1 and is fitted outside the guide frame 4. A row of rectangular brackets 6 is provided on the guide frame 4. The rectangular brackets 6 and the guide frame 4 are slidably connected, and adjacent rectangular brackets 6 are movably connected by a hinge rod group 7. When the rectangular brackets 6 move along the guide frame 4, they can pass through the entrance and exit window 5. The rectangular bracket 6 is used to support tableware, such as plates. The two ends of the rectangular bracket 6 are connecting sleeves that are sleeved on the outside of the guide post. The connecting sleeves are nested with friction-increasing rubber sleeves. There is a certain frictional resistance between the friction-increasing rubber sleeves and the guide post. The hinge rod group 7 is composed of two connecting rods connected end to end. When a plate is inserted into each rectangular bracket 6, and then the outermost rectangular bracket 6 is pushed or pulled, the spacing between a row of plates will increase or decrease under the restriction of the hinge rod group 7, and the spacing will remain constant after the increase or decrease.

[0024] A slide block 8 is provided between two rows of guide frames 4. A positioning sleeve 9 is provided on the slide block 8. A bracket 101 is rotatably connected to the top of the positioning sleeve 9. A photoelectric detector 102 is detachably connected to one side of the bracket 101. Services include new material testing, metrology, related standardization, and certification; industrial vision, visual intelligence, and AI. The photoelectric detector 102 is used in visual inspection, visual measurement, and visual testing. The photoelectric detector 102 mainly uses the principles of light reflection and occlusion to detect the presence, position, color, or surface condition of objects. The photoelectric detector 102 used for detecting oil stains on tableware (such as plates) mainly uses the ultraviolet fluorescence method. The specific principle is that the oil stains (grease, fatty acids, etc.) on the surface of the plate will emit characteristic fluorescence (~450-500nm) under ultraviolet light (UV, ~365nm). The photoelectric sensor in the probe of the photoelectric detector 102 measures the fluorescence intensity. The higher the intensity, the more oil stains there are. The result is displayed as a percentage of cleanliness (0-100%). At present, there are already detectors on the market that can continuously move to detect surface oil stains. The photoelectric detector 102 in this technical solution can be selected from the existing detectors. In practice, the tail of the photoelectric detector 102 is fixedly connected to the flange of the bracket 101 via screws. This photoelectric detector 102 is used to detect oil stains on the plates placed on the rectangular bracket 6. When the slide 8 moves, it will drive the photoelectric detector 102 to move and perform mobile oil stain detection on a row of plates. After the bracket 101 rotates at a certain angle, it can drive the photoelectric detector 102 to perform mobile oil stain detection on another row of plates.

[0025] In this embodiment, the slide 8 includes a limiting sleeve 81 and a rotatable connecting sleeve 82 located below the limiting sleeve 81. The limiting sleeve 81 is sleeved on the outside of the positioning sleeve 9 and the two are rotatably connected. Specifically, the bottom wall of the limiting sleeve 81 is connected to a connecting tube sleeved on the outside of the connecting sleeve 82 via a positioning rod, and the connecting tube and the connecting sleeve 82 are rotatably connected. A sector toothed plate 91 is fixed to the bottom of the positioning sleeve 9, and a transmission gear 821 that meshes with the sector toothed plate 91 is fixedly sleeved on the outside of the connecting sleeve 82. When the connecting sleeve 82 rotates, it can indirectly drive the positioning sleeve 9 to rotate. A bevel gear 1011 is fixed to the lower part of the bracket 101. The bottom wall of the bevel gear 1011 is fixed to a limiting shaft, and the top wall of the positioning sleeve 9 is fixedly connected to a support sleeve sleeved on the outside of the limiting shaft. The support sleeve and the limiting shaft are rotatably connected. The top of the limiting sleeve 81 is fixed with a limiting plate 812 that meshes with the bevel gear 1011. The limiting plate 812 has a fan-shaped bevel gear structure. When the positioning sleeve 9 rotates, the bracket 101 will rotate relative to the positioning sleeve 9 under the meshing cooperation of the limiting plate 812 and the bevel gear 1011. Therefore, when the connecting sleeve 82 is controlled to rotate left and right, the bracket 101 will drive the photoelectric detector 102 to move left and right. Then, when the slide 8 is controlled to move, the two rows of plates can be photoelectrically detected for oil stains.

[0026] Furthermore, an upper rotating shaft 104 and a lower rotating shaft 105 are respectively provided between one side of the cabinet 1 and one side inside the slotted cover 3, passing through the limiting sleeve 81 and the connecting sleeve 82. The upper rotating shaft 104 and the limiting sleeve 81 are screwed together. One end of the upper rotating shaft 104 and the lower rotating shaft 105 are rotatably connected to the inner side wall of the slotted cover 3, and the other end of the upper rotating shaft 104 and the lower rotating shaft 105 are rotatably connected to the cabinet 1. When the upper rotating shaft 104 rotates, it can drive the slide 8 to move through the limiting sleeve 81. The lower rotating shaft 105 and the connecting sleeve 82 are axially slidably connected. When the lower rotating shaft 105 rotates, it can control the rotation of the connecting sleeve 82.

[0027] Furthermore, a heat insulation cover 21 is fixed between the two sides of the disinfection chamber 2. One end of the heat insulation cover 21 is connected to the outside. An upper control motor 106 and a lower control motor 107 are fixedly connected to one side inside the heat insulation cover 21. The heat insulation cover 21 separates the upper control motor 106 and the lower control motor 107 from the disinfection chamber 2, without affecting the normal heat dissipation of the upper control motor 106 and the lower control motor 107. The output shafts of the upper control motor 106 and the lower control motor 107 are fixedly connected to one end of the upper rotating shaft 104 and the lower rotating shaft 105, respectively. Both the upper control motor 106 and the lower control motor 107 can be servo motors or DC motors.

[0028] A sealing plate 103 is fitted onto the guide frame 4, located on the outside of the cabinet 1. The function of the sealing plate 103 is to block the entrance / exit window 5. One side of the sealing plate 103 is fixedly connected to a rectangular bracket 6 via a connecting shaft. When the sealing plate 103 moves away from the entrance / exit window 5, it can pull all the rectangular brackets 6 out of the disinfection chamber 2. When the sealing plate 103 moves to its limit position towards the entrance / exit window 5, it will block the entrance / exit window 5, making the disinfection chamber 2 in a closed state. The sealing plate 103 has a built-in magnet, and the sealing plate 103 is magnetically attracted to one side of the cabinet 1. The inner side of the slotted cover 3 is fixedly connected to a limiting plate that is magnetically attracted to the magnet. This arrangement allows the sealing plate 103 to stay stably in both extreme positions.

[0029] Furthermore, a crossbeam 108 is provided above the positioning sleeve 9. The middle part of the bottom of the crossbeam 108 is fixedly connected to the top wall of the limiting sleeve 81 through a support plate. When the positioning sleeve 9 rotates back and forth, it will drive the crossbeam 108 to swing up and down. An L-shaped baffle 1031 is fixedly connected to the outer side of the sealing plate 103, which is close to the outer periphery and cooperates with one end of the crossbeam 108. After one end of the crossbeam 108 swings down, it enters between the adjacent L-shaped baffle 1031 and the corresponding sealing plate 103. The other end of the crossbeam 108 will leave between the adjacent L-shaped baffle 1031 and the corresponding sealing plate 103. Then, when the slide block 8 is controlled to move, the sealing plate 103 will pull the corresponding sealing plate 103. That is to say, by controlling the positioning sleeve 9 to rotate back and forth at a certain angle, the crossbeam 108 can drive a sealing plate 103 to move at different times.

[0030] In this embodiment, cabinet doors 109 are provided on the left and right sides of the trough-shaped cover 3. One end of the cabinet door 109 is hinged to the cabinet body 1, and two roller carriers 110 are fixed inside the door. When the cabinet door 109 is closed, it will block the trough-shaped cover 3. The roller carrier 110 is used to hold tableware (such as chopsticks, spoons, knives and forks, etc.). An ultraviolet germicidal lamp 120 is fixedly connected to the cabinet door 109 above the roller carrier 110. When the roller carrier 110 is started, it will cause the tableware inside to tumble, so that the ultraviolet germicidal lamp 120 can sterilize and disinfect the tableware without dead angles.

[0031] Specifically, the roller carrier 110 includes a trough support 1101 and a front cage 1102 and a rear cage 1103 located within the trough support 1101. A positioning plate is fixedly connected to one side of the cabinet door 109 and to one side of the trough support 1101. The opening ends of the front cage 1102 and the rear cage 1103 are opposite each other and coaxial. Both the front cage 1102 and the rear cage 1103 are made of stainless steel round bars and stainless steel discs welded together. The space between the front cage 1102 and the rear cage 1103 is a space for placing tableware. When the front cage 1102 and the rear cage 1103 rotate synchronously and in the same direction, the tableware inside will tumble. The front cage 1102 and the rear cage 1103 are respectively fixed to the opposite sides of the front shaft 11021 and the rear shaft 11031. A guide sleeve 11011 is rotatably connected to the groove support 1101 and sleeved outside the front shaft 11021. The guide sleeve 11011 is slidably connected to the front shaft 11021, and the rear shaft 11031 is rotatably connected to the groove support 1101. The distance between the front cage 1102 and the rear cage 1103 can be adjusted by pushing and pulling the front shaft 11021, which makes it convenient to place tableware of different lengths. It should be noted that the outer wall of the front axle 11021 has multiple axially distributed spherical grooves, and the inner circumferential wall of the guide sleeve 11011 has a limiting groove. A support spring is installed in the limiting groove, and a retaining ball is installed at one end of the support spring. The retaining ball abuts against the outer wall of the front axle 11021. When the retaining ball abuts against one of the spherical grooves, the front axle 11021 will not move axially easily. The front axle 11021 can only be pushed when the force is pulled.

[0032] An arc-shaped support plate 130 is provided near the bottom between the front cage-type cylinder 1102 and the rear cage-type cylinder 1103. The arc-shaped support plate 130 is used to support the tableware between the front cage-type cylinder 1102 and the rear cage-type cylinder 1103. When the front cage-type cylinder 1102 moves away from the tableware, the tableware will be supported by the arc-shaped support plate 130 and will not fall. The bottom wall of the arc-shaped support plate 130 is fixedly connected to the bottom of the groove-shaped support 1101 by a support rod. Furthermore, a drive shaft is installed on the slotted support 1101. The drive shaft is rotatably connected to two vertical plates on the slotted support 1101. The two ends of the drive shaft are connected to the guide sleeve 11011 and the rear shaft 11031 respectively through belt drive group one. When the drive shaft is rotated, it can drive the front cage cylinder 1102 and the rear cage cylinder 1103 to rotate. Then, a control motor three is fixedly installed on one side inside the slotted support 1101. The output shaft of the control motor three is connected to the drive shaft through belt drive group two. The control motor three is a servo motor. When the control motor three is started, the drive shaft will be driven to rotate.

[0033] In this embodiment, a control box is fixedly installed at the bottom of the cabinet 1. The control box contains a controller, which is electrically connected to the aforementioned electric heating tube, upper control motor, lower control motor, control motor three, and photoelectric detector 102. An operation panel electrically connected to the controller is fixedly installed on one side of the cabinet 1. The corresponding disinfection and oil stain detection programs of this disinfection cabinet can be started through the operation panel.

[0034] Working principle: When in use, first open the cabinet door 109, control the lower rotating shaft 105 to rotate, the connecting sleeve 82 is driven to rotate, the transmission gear 821 drives the positioning sleeve 9 to rotate through the sector tooth plate 91, the positioning sleeve 9 drives the crossbeam 108 to tilt at a certain angle, at this time the crossbeam 108 enters the L-shaped baffle 1031 on one of the sealing plates 103, then control the upper rotating shaft 104 to rotate, under the action of the rotation driving force, the entire slide 8 moves away from the cabinet 1. At this time, under the pull of the hinge rod group 7, the current sealing plate 103 will pull multiple rectangular brackets 6 to pass through the inlet and outlet window 5 in sequence and enter the slotted cover 3. At this time, the distance between adjacent rectangular brackets 6 is at its maximum. Then, insert the plate into each rectangular bracket 6, and insert the plate into the rectangular bracket 6 on another guide frame 4 in the same way. The oil stain detection program is initiated by controlling the lower rotating shaft 105 to rotate a certain angle, ensuring that the crossbeam 108 does not enter the L-shaped baffle 1031. Simultaneously, the detection end of the photoelectric detector 102 faces upwards towards one of the guide frames 4. When the slide 8 is moved horizontally, the photoelectric detector 102 performs a moving oil stain detection on the back of a row of plates. During detection, the linear array ultraviolet light source of the light-emitting module at the detection end of the photoelectric detector 102 emits ultraviolet fluorescence. This fluorescence is reflected when it shines on the plate, and the receiving module at the detection end receives the reflected light. The intensity of the reflected light determines whether there is oil stain or the amount of oil stain. When oil stain is detected, the alarm module on the photoelectric detector 102 will sound an alarm. After controlling the lower rotating shaft 105 to rotate another certain angle, and then controlling the slide 8 to move horizontally again, the photoelectric detector 102 will perform an oil stain detection on the front of a row of plates. After one row of plates on one guide frame 4 has been inspected, the lower rotating shaft 105 is rotated twice at small angles. Combined with the movement of the slide block 8, this allows the photoelectric detector 102 to inspect the oil stains on both sides of another row of plates on the other guide frame 4. After inspection, the upper rotating shaft 104 is rotated, and then the lower rotating shaft 105 is rotated, causing the crossbeam 108 to enter an L-shaped baffle 1031. The upper rotating shaft 104 is then rotated again, causing the crossbeam 108 to pull the sealing plate 103 towards the cabinet 1. The sealing plate 103 pushes each rectangular bracket 6 into the disinfection chamber 2 of the cabinet 1, blocking the entrance / exit window 5. This process is repeated to push another row of plates into the disinfection chamber 2. Then, the electric heating rod is activated to heat and disinfect the plates in the disinfection chamber 2.Manually pull the front shaft 11021. At this time, the distance between the front cage 1102 and the rear cage 1103 increases. Place chopsticks between the front cage 1102 and the rear cage 1103. Then reset the front shaft 11021. At this time, a large number of chopsticks will be supported by the front cage 1102 and the rear cage 1103. Then turn on the ultraviolet sterilization lamp 120 and start the control motor three. At this time, the front cage 1102 and the rear cage 1103 will rotate at a low speed, and the chopsticks inside the front cage 1102 and the rear cage 1103 will tumble. The ultraviolet sterilization lamp 120 can perform comprehensive sterilization and disinfection on the tumbling chopsticks.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
