Description

Technical Field

[0001] This invention relates to the field of food sterilization technology, and more specifically, to a food heating and sterilization device. Background Technology

[0002] High-temperature cooking and sterilization involves heating food for a specified time to achieve disinfection, and is commonly used in food processing.

[0003] High-temperature sterilizers, as an important sterilization device, use a spray mechanism to spray hot water or steam to sterilize food. Food contains a wide variety of bacteria with varying heat resistance. Existing high-temperature sterilizers have limited functionality, using ultra-high temperature steam to kill bacteria. However, ultra-high temperature steam can significantly affect the flavor of food. Furthermore, existing sterilizers keep food stationary during sterilization, resulting in poor sterilization of food piled up inside.

[0004] Ultraviolet (UV) disinfection technology is also a physical disinfection method without chemical additives. Its main function is to use UV light to kill microorganisms such as bacteria, viruses, and fungi. UV light can destroy the DNA or RNA structure of microorganisms, causing them to lose their ability to replicate or reproduce, thereby achieving the effect of sterilization and disinfection. Therefore, it is necessary to design a food heating and sterilization device with UV sterilization function. In view of this, we propose a food heating and sterilization device. Summary of the Invention

[0005] The purpose of this invention is to provide a food heating and sterilization device to solve the technical problem of limited functionality in food heating and sterilization devices.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a food heating and sterilization device, including a pot body, a pot lid mechanism arranged on one side of the pot body, a spray sterilization mechanism arranged on the pot body, an ultraviolet sterilization mechanism arranged in the inner cavity of the pot body, a placement mechanism arranged in the gap of the ultraviolet sterilization mechanism, a functional mechanism arranged in the placement mechanism, the gap between the placement mechanism and the functional mechanism forming a placement cavity, and a rotating mechanism arranged on one side of the ultraviolet sterilization mechanism.

[0007] The rotating mechanism has a first output end and a second output end. The first output end passes through the placement mechanism and is connected to the input end of the functional mechanism. The second output end is connected to the input end of the placement mechanism.

[0008] In this invention, when the rotating mechanism rotates in the forward direction, the first and second output ends rotate at a relative differential speed, causing the functional mechanism and the placement mechanism to rotate at a differential speed for mixing. When the rotating mechanism rotates in the reverse direction, the first and second output ends rotate at the same speed, causing the functional mechanism and the placement mechanism to rotate at the same speed for centrifugal dehydration. The present invention uses a forward, slow rotation of the functional mechanism to dynamically mix the food, allowing the ultraviolet sterilization mechanism and the spray sterilization mechanism to sterilize the food twice in sequence, resulting in good sterilization effect. Furthermore, by setting the rotating mechanism to rotate in the reverse direction at high speed to centrifuge and remove water adhering to the food, the high-temperature dehydration time is reduced, thus reducing the overall high-temperature sterilization time of the food and preserving the food flavor to a greater extent. This solves the technical problem of the current food heating and sterilization equipment having only one function.

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

[0026] 1. The present invention features a forward slow rotation mechanism that dynamically mixes the food, allowing the ultraviolet sterilization mechanism and the spray sterilization mechanism to sterilize the food twice in sequence, resulting in a good sterilization effect. In particular, by setting up a reverse high-speed rotation mechanism, the water attached to the food is centrifuged and thrown off, reducing the high-temperature dehydration time. Overall, the time of high-temperature sterilization of the food is reduced, and the flavor of the food is preserved to a greater extent. This solves the technical problem of the current food heating and sterilization equipment having a single function.

[0027] 2. Through further design of the ultraviolet sterilization component, this invention enables the arc plate to prevent water or water vapor from entering the installation cavity during sterilization by the spray sterilization mechanism and during centrifugal dehydration of food, thus protecting the ultraviolet lamp column. Furthermore, by setting several adjusting gears connected by adjusting gear rings, when the adjusting screw is rotated with a tool, the adjusting rod drives the corresponding adjusting gear to rotate, which in turn causes the adjusting gear ring to drive all the other adjusting gears to rotate, which in turn causes the connecting rod to drive the arc plate to rotate. This allows for convenient and quick adjustment of ultraviolet sterilization or other functions, further enhancing functionality.

[0028] 3. Through further design of the ultraviolet sterilization component, sliding arc groove A, and sliding arc groove B, this invention ensures that when adjusting and using ultraviolet sterilization or other functions, at least a number of sliding strips A provide locking force to prevent the arc plate from rotating during use. Furthermore, during sterilization in the spray sterilization mechanism and during centrifugal dehydration of food, the sliding strip A and the locking arc surface of the locking arc groove A and the sliding strip B and the locking arc surface of the locking arc groove B are in close contact, which extends the distance for water or water vapor to enter the installation cavity, further improving the protection of the ultraviolet lamp column.

[0029] 4. Through further design of the functional mechanism, this invention enables the centrifugal force to exert an eccentric force on the sub-plate and the mother plate during high-speed rotation. This causes the mother plate to rotate relative to the rotating rod A, while the sub-plate and mother plate slide relative to each other. The tension spring C extends, and the shape formed by several mother plates and sub-plates changes from a flower shape to a circle. This reduces the space of the placement cavity formed by the gaps between the placement mechanism and the functional mechanism, allowing the food to be evenly gathered on the placement cavity. This increases the centrifugal radius, thereby increasing the centrifugal force on the surface moisture of the food and improving the centrifugal water removal effect. During low-speed rotation, under the elastic force of the tension spring C, several mother plates and sub-plates re-form a flower shape, increasing and reducing the space of the placement cavity formed by the gaps between the placement mechanism and the functional mechanism, improving the food mixing effect, and further enhancing the ultraviolet and high-temperature sterilization effects.

[0058] like Figures 1 to 15 As shown, the present invention relates to a food heating and sterilization device, comprising a pot body 1, a pot cover mechanism 2 arranged on one side of the pot body 1, a spray sterilization mechanism 3 arranged on the pot body 1, an ultraviolet sterilization mechanism 4 arranged in the inner cavity of the pot body 1, a placement mechanism 5 arranged in the gap of the ultraviolet sterilization mechanism 4, a functional mechanism 6 arranged in the placement mechanism 5, and a placement cavity formed by the gap between the placement mechanism 5 and the functional mechanism 6, and a rotating mechanism 7 arranged on one side of the ultraviolet sterilization mechanism 4.

[0059] The rotating mechanism 7 has a first output end and a second output end. The first output end passes through the placement mechanism 5 and is connected to the input end of the functional mechanism 6. The second output end is connected to the input end of the placement mechanism 5.

[0060] When the rotating mechanism 7 rotates in the forward direction, the first output end and the second output end rotate at a relative differential speed, causing the functional mechanism 6 and the placement mechanism 5 to form a stirring state of differential rotation. When the rotating mechanism 7 rotates in the reverse direction, the first output end and the second output end rotate at the same speed, causing the functional mechanism 6 and the placement mechanism 5 to form a centrifugal dewatering state of rotating at the same speed.

[0061] In an embodiment of the present invention, the ultraviolet sterilization mechanism 4 includes a ring block A41 and a ring block B42. The ring block A41 is fixed at the head end of the inner cavity of the pot body 1, and the ring block B42 is fixed at the tail end of the inner cavity of the pot body 1. A plurality of ultraviolet sterilization components 43 are arranged in a ring-shaped and equally spaced structure in the gap between the ring block A41 and the ring block B42.

[0062] In an embodiment of the present invention, the rotating mechanism 7 includes a baffle 71, a motor 73, and a turntable 77. The baffle 71 is fixed to the tail end of the ring block B42, and an internal gear ring 72 is fixed to the head end of the baffle 71. The outer edge of the internal gear ring 72 is fixedly connected to the inner edge of the ring block B42. The motor 73 is fixed to the tail end of the baffle 71. The output shaft of the motor 73 extends through the baffle 71 into the gap of the internal gear ring 72 and is fixedly connected to a connecting shaft 74. A sun gear 75 is fixed on the connecting shaft 74. The sun gear 75 and the internal gear ring 72 are meshed and connected by planetary gears 76 arranged in a ring with equal spacing. The turntable 77 is rotatably mounted on the connecting shaft 74 relative to the position of the internal gear ring 72. The planetary gears 76 are rotatably connected to the turntable 77. An output part 78 is arranged at the head end of the turntable 77. The present invention, through the above arrangement, causes the output shaft of the motor 73 to rotate, thereby driving the connecting shaft 74 and the sun gear 75 to rotate, and the planetary gear 76 to revolve around the sun gear 75, causing the turntable 77 to rotate, and the turntable 77 and the connecting shaft 74 to rotate at different speeds.

[0063] In an embodiment of the present invention, the output section 78 includes a rotating ring A781, a rotating ring B782, and a rotating ring C783. At least one limiting protrusion is fixedly provided on the inner surface of each of the rotating rings A781, B782, and C783. The rotating ring A781 is fixedly disposed at the head end of the turntable 77, the rotating ring B782 is rotatably disposed within the rotating ring A781, and the rotating ring C783 is rotatably disposed within the rotating ring B782.

[0064] The outer surface of the rotating ring B782 is fixed with a plurality of first limiting arc grooves 784 in an annular and equally spaced structure. The first limiting arc grooves 784 are adapted to the inner edge surface of the rotating ring A781. The first limiting arc grooves 784 and the inner edge surface of the rotating ring A781 form a first limiting cavity. A first limiting post 785 is movably provided in the first limiting cavity. The first limiting post 785 is adapted to the first limiting cavity.

[0065] The rotating ring C783 is fixedly connected to the connecting shaft 74. The outer surface of the rotating ring C783 is provided with several second limiting arc grooves 786 in an annular and equally spaced structure. The second limiting arc grooves 786 are adapted to the inner edge surface of the rotating ring B782. The second limiting arc grooves 786 and the rotating ring B782 form a second limiting cavity. A second limiting post 787 is movably connected in the second limiting cavity. The second limiting post 787 is adapted to the second limiting cavity.

[0066] The depth of the first limiting cavity gradually increases in the clockwise direction, while the depth of the second limiting cavity gradually decreases in the clockwise direction.

[0067] The first output end is formed by a coupling 74, and the second output end is formed by a rotating ring B782. Through the design of the output section 78, in a static state, at least one first limiting post 785 and a second limiting post 787 are respectively located in the middle of the first and second limiting cavities. This allows the motor 73 to rotate slowly in the forward direction, driving the coupling 74, the sun gear 75, and the rotating ring C783 to rotate slowly in the forward direction, which in turn drives the functional mechanism 6 to rotate slowly in the forward direction. This causes the second limiting post 787 to move to the wide opening of the second limiting cavity. The turntable 77 rotates differentially relative to the coupling 74. The forward rotation of the turntable 77 drives the rotating ring A781 to rotate slowly in the forward direction, causing the first limiting post 785 to have a force moving towards the narrow opening of the first limiting cavity. This causes the rotating ring B782 to rotate slowly in the forward direction, and the rotating ring B782 drives the functional mechanism 6 to rotate slowly. Thus, the functional mechanism 6 and the placement mechanism 5 constitute a [missing information - likely a specific configuration or structure]. In the differential rotation mixing state, when the motor 73 rotates in the opposite direction at high speed, it drives the connecting shaft 74, the sun gear 75, and the rotating ring C783 to rotate in the opposite direction at high speed. This causes the second limiting post 787 to have a force that moves towards the narrow opening of the second limiting cavity, causing the rotating ring C783 to drive the rotating ring B782 to rotate at the same speed. Since the rotation speed of the turntable 77 and the rotating ring A781 is less than the rotation speed of the connecting shaft 74, the speed of the rotating ring B782 is greater than the speed of the rotating ring A781. The rotating ring B782 rotates in the opposite direction to the rotating ring A781, and the first limiting post 785 moves to the wide opening of the first limiting cavity. At the same time, the rotating ring C783 drives the rotating ring B782 to rotate at the same speed, which drives the functional mechanism 6 and the placement mechanism 5 to rotate at high speed, causing the functional mechanism 6 and the placement mechanism 5 to form a centrifugal dewatering state rotating at the same speed.

[0068] In an embodiment of the present invention, a rotating groove 411 is provided on the outer edge surface of the ring block A41, and an annular cavity 412 is provided on the rotating groove 411.

[0069] In an embodiment of the present invention, the ultraviolet sterilization component 43 includes a mounting post 431, with both ends of the mounting post 431 fixedly connected to ring block A41 and ring block B42 respectively. A mounting cavity 432 is formed within the mounting post 431, and an ultraviolet lamp column 433 is fixedly mounted within the mounting cavity 432. An eight-shaped groove 434 is formed on the outer edge of the mounting post 431 opposite to the mounting cavity, with the narrow end of the eight-shaped groove 434 communicating with the mounting cavity 432. Through this arrangement, the emitted ultraviolet light passes through the eight-shaped groove 434 to sterilize the food. The eight-shaped groove 434 prevents the groove wall from blocking the ultraviolet light, thus increasing the sterilization range of the ultraviolet irradiation.

[0070] In an embodiment of the present invention, the two ends of the figure-eight groove 434 are respectively provided with sliding arc groove A435 and sliding arc groove B436. An arc plate 437 is slidably connected on the sliding arc groove B436. The arc plate 437 is slidably engaged with the sliding arc groove A435. The head end of the arc plate 437 extends out of the figure-eight groove 434 and is fixedly provided with a connecting rod 430. The connecting rod 430 is rotatably connected with the ring block A41. The ring block A41 is inserted into the ring cavity 412 and is fixedly provided with an adjusting gear 438. Several adjusting gears 438 are meshed and connected through an adjusting gear ring 439. The adjusting gear ring 439 is rotatably connected to the rotating groove 411 through an adjusting ring 440. One of the adjusting gears 438 is fixedly provided with an adjusting rod 441 at its head end. The head end of the adjusting rod 441 extends out of the ring cavity 412 to the outside of the ring block A41 and is fixedly provided with an adjusting screw block 442. This invention, through further design of the ultraviolet sterilization component 43, enables the arc plate 437 to prevent water or water vapor from entering the mounting cavity 432 during sterilization by the spray sterilization mechanism 3 and during centrifugal dehydration of food, thus protecting the ultraviolet lamp column 433. Furthermore, by setting several adjusting gears 438 that are meshed and connected through adjusting gear rings 439, when the adjusting screw block 442 is rotated with a tool, the adjusting rod 441 drives the corresponding adjusting gear 438 to rotate, causing the adjusting gear ring 439 to drive all the other adjusting gears 438 to rotate, which in turn causes the connecting rod 430 to drive the arc plate 437 to rotate. This allows for adjustment of ultraviolet sterilization or other functions, making adjustment convenient and quick, and further enhancing functionality.

[0071] In an embodiment of the present invention, a plurality of snap-fit ​​arc grooves A4351 are uniformly provided on the sliding arc groove A435, and a plurality of snap-fit ​​arc grooves B4361 are uniformly provided on the sliding arc groove B436.

[0072] The arc plate 437 has several sliding grooves A4371 and several sliding grooves B4372 at both ends. A sliding strip A4373 is slidably connected in the sliding groove A4371. The sliding strip A4373 and the sliding groove A4371 are elastically connected by several springs A4374 evenly arranged. A sliding strip B7375 is slidably connected in the sliding groove B4372. The sliding strip B7375 and the sliding groove B4372 are elastically connected by several springs B7376 evenly arranged.

[0073] Among them, a number of sliders A4373 are adapted to a number of snap-fit ​​arc grooves A4351 and a number of snap-fit ​​arc grooves B4361, and sliders A4373 are snap-fitted to snap-fit ​​arc grooves A4351 and B4361. A number of sliders B7375 are adapted to a number of snap-fit ​​arc grooves B4361, and sliders B7375 are snap-fitted to snap-fit ​​arc grooves B4361. This invention, through further design of the ultraviolet sterilization component 43, sliding arc groove A435, and sliding arc groove B436, ensures that when adjusting and using ultraviolet sterilization or other functions, at least a number of sliding strips A4373 provide locking force to prevent the arc plate 437 from rotating during use. Furthermore, during sterilization by the spray sterilization mechanism 3 and during centrifugal dehydration of food, the sliding strip A4373 and the locking arc surface of the locking arc groove A4351 and the sliding strip B7375 and the locking arc surface of the locking arc groove B4361 are in close contact, which extends the distance for water or water vapor to enter the mounting cavity 432, further improving the protection of the ultraviolet lamp column 433.

[0074] In an embodiment of the present invention, the placement mechanism 5 includes an inner ring 51 and an outer ring 52.

The rotating block A61 is rotatably disposed in the inner ring 51, and the rotating block B62 is rotatably disposed in the circular groove 56. The rotating block A61 and the rotating block B62 are fixedly connected by a horizontal shaft 63. The head end of the connecting shaft 74 passes through the connecting circular block 57 and the circular plate 55 in sequence and is fixedly connected to the rotating block B62. Functional components 64 are arranged in a ring-shaped and equally spaced structure in the gap between the rotating blocks A61 and B62. Any two adjacent functional components 64 are rotatably connected by a rotating rod A65. The two ends of the rotating rod A65 are rotatably connected to the rotating blocks A61 and B62 respectively.

[0076] Functional component 64 includes a first rotating rod B641 and a second rotating rod B642. The first rotating rod B641 is fixedly connected to the horizontal shaft 63 through several connecting seats 643. Several first annular grooves 644 are opened at both ends of the first rotating rod B641. Several second annular grooves 645 are opened at both ends of the second rotating rod B642. Two sub-plates 646 are rotatably connected to the second rotating rod B642. The two sub-plates 646 are arranged in an alternating structure. Several slots 640 are opened at the centripetal end of the sub-plates 646 relative to the positions of the several second annular grooves 645. A tension spring C647 is arranged in the slot 640. The two ends of the tension spring C647 are movably connected to the first annular groove 644 and the second annular groove 645, respectively. A mother plate 648 is slidably connected to both sub-plates 646. The mother plate 648 is rotatably connected to the rotating rod A65. The eccentric end of the mother plate 648 is in contact with the circular groove 56. This invention, through further design of functional mechanism 6, enables centrifugal force during high-speed rotation to exert an eccentric force on the sub-plate 646 and the mother plate 648, causing the mother plate 648 to rotate relative to the rotating rod A65, while the sub-plate 646 and the mother plate 648 slide relative to each other. The tension spring C647 extends, and the shape formed by several mother plates 648 and sub-plates 646 changes from a flower shape to a circle, reducing the placement cavity space formed by the gap between the placement mechanism 5 and functional mechanism 6. This allows food to be evenly gathered in the placement cavity, increasing the centrifugal radius and thus improving the centrifugal force on the surface moisture of the food, enhancing the centrifugal water removal effect. During low-speed rotation or at rest, under the elastic force of the tension spring C647, several mother plates 648 and sub-plates 646 re-form a flower shape, increasing and reducing the placement cavity space formed by the gap between the placement mechanism 5 and functional mechanism 6, improving the food mixing effect, and further enhancing the ultraviolet and high-temperature sterilization effects.

[0077] Working principle: This embodiment provides a food heating and sterilization device. When using it, ultraviolet sterilization or high-temperature sterilization can be selected as needed.

[0078] Sterilization is performed using the ultraviolet sterilization mechanism 4. The adjusting screw 442 is rotated using a tool, and the adjusting rod 441 drives the corresponding adjusting gear 438 to rotate, causing the adjusting gear ring 439 to drive all the other adjusting gears 438 to rotate, causing the connecting rod 430 to drive the arc plate 437 to rotate, so that the arc plate 437 rotates into the sliding arc groove B436, and all ultraviolet lamp columns 433 are turned on through the external control mechanism.

[0079] Simultaneously, the motor 73 is controlled by an external control mechanism to rotate slowly in the forward direction, driving the connecting shaft 74, the sun gear 75, and the rotating ring C783 to rotate slowly in the forward direction, which in turn drives the functional mechanism 6 to rotate slowly in the forward direction. This causes the second limiting post 787 to move to the wide opening of the second limiting cavity. The turntable 77 rotates at a different speed relative to the connecting shaft 74. The forward rotation of the turntable 77 drives the rotating ring A781 to rotate slowly in the forward direction, causing the first limiting post 785 to have a force that moves towards the narrow opening of the first limiting cavity. This causes the rotating ring B782 to rotate slowly in the forward direction. The rotating ring B782 drives the functional mechanism 6 to rotate slowly, thereby making the functional mechanism 6 and the placement mechanism 5 form a stirring state of differential rotation. At this time, several mother plates 648 and daughter plates 646 form a flower shape. The differential rotation of the placement mechanism 5 and the functional mechanism 6 stirs the food in the placement cavity to improve the sterilization effect of the ultraviolet sterilization mechanism 4.

[0080] When using the spray sterilization mechanism 3 for sterilization, the tool is used to rotate the adjusting screw block 442 so that the end of the arc plate 437 is rotated into the sliding arc groove A435 to protect the ultraviolet lamp column 433; hot water or steam is sprayed out by the external control mechanism spray sterilization mechanism 3 to sterilize the food in the stirred state.

[0081] After spray sterilization, the motor 73 is controlled by an external control mechanism to rotate in reverse at high speed, driving the coupling 74, the sun gear 75, and the rotating ring C783 to rotate in reverse at high speed. This causes the second limiting post 787 to have a force moving towards the narrow opening of the second limiting cavity, resulting in the rotating ring C783 driving the rotating ring B782 to rotate at the same speed. Since the rotation speed of the turntable 77 and the rotating ring A781 is less than the rotation speed of the coupling 74, the speed of the rotating ring B782 is greater than the speed of the rotating ring A781. The rotating ring B782 rotates in the opposite direction to the rotating ring A781, and the first limiting post 785 moves to the wide opening of the first limiting cavity. At the same time, the rotating ring C783 drives the rotating ring B782 to rotate at the same speed. The functional mechanism 6 and the placement mechanism 5 rotate at high speed, causing them to rotate at the same speed in a centrifugal dehydration state. At this time, the centrifugal force causes the daughter plate 646 and the mother plate 648 to have an eccentric force, causing the mother plate 648 to rotate relative to the rotating rod A65, and the daughter plate 646 and the mother plate 648 to slide relative to each other. The tension spring C647 extends, and several mother plates 648 and daughter plates 646 form a shape that changes from a flower shape to a circle, reducing the placement cavity space formed by the gap between the placement mechanism 5 and the functional mechanism 6. This allows the food to be evenly gathered on the placement cavity, increasing the centrifugal radius, thereby increasing the centrifugal force on the surface moisture of the food and improving the centrifugal dehydration effect.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
