Description

Technical Field

[0001] This utility model relates to the field of sterilization pot technology, and in particular to a steam sterilization pot. Background Technology

[0002] An autoclave is a sealed, pressurized heater used to heat and sterilize food sealed in containers. According to the different heating media, it is divided into steam autoclaves, electric heating autoclaves, and hot water autoclaves. Steam autoclaves mainly use steam generated by a boiler at a certain pressure as a heat source, and directly heat and sterilize through boiler steam. It has the characteristics of fast heating speed, high thermal efficiency, and easy control of heating temperature.

[0003] According to CN217523860U, a utility model patent for a steam sterilizer includes a sterilizer body. One end of the sterilizer body has a fixed end cap, and the other end has a movable end cap. A carrying rack is installed inside the sterilizer body and fixed to the movable end cap. The fixed end cap is fixedly installed to the end of the sterilizer body. A steam inlet pipe is located in the middle of the fixed end cap. One end of the steam inlet pipe is rotatably connected to a steam pipe inlet inside the sterilizer body via a universal joint. An air nozzle is installed on the steam pipe. Both ends of the steam pipe are fixedly installed to the sides of an annular rotating plate. An external gear ring and a drive gear are located on the outer side of the annular rotating plate, and the drive gear engages with the external gear ring. This utility model uses the annular rotating plate to drive the steam pipe on it to rotate, so that steam is evenly distributed on the carrying rack, resulting in uniform heating and good sterilization of the materials on the carrying rack.

[0004] While the above technical solution can achieve the effect of steam sterilization, heating the material by rotating the steam pipe will result in the material on the shelf being heated first, while the material piled inside cannot be heated simultaneously. Only when the temperature inside the sterilization pot rises can the internal material of the piled material be heated, which will cause uneven heating of the material piled on the shelf. Utility Model Content

[0005] The purpose of this invention is to provide a steam sterilizer that can sterilize materials with steam. During the sterilization process, it can not only ensure the sterilization effect on the materials, but also achieve simultaneous internal and external heat sterilization of the materials piled on the rack, thereby improving the sterilization effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A steam sterilizer includes a pot body with an open front end and capable of heat preservation, and a sealing cover hinged to and sealed to one side of the front opening of the pot body. The pot body is inclined downward from back to front. An air blowing component is fitted on the inner wall of the pot body, with one end extending out of the rear end of its outer wall. The end of the air blowing component extending out of the outer wall of the pot body is equipped with a first quick connector communicating with it. A gap is left between the lower end of the air blowing component and the bottom of the inner wall of the pot body. A fixing frame is fitted on the inner wall of the pot body near its lower end. Sliding components are provided on both the left and right sides of the upper end of the fixing frame along its length.

[0008] The upper ends of the two sliding components are slidably connected to a detachable shelf. Multiple ventilation components are slidably connected inside the shelf. The rear ends of each pair of adjacent ventilation components are connected by a flexible connecting pipe. The front end of the air blowing component is equipped with a second quick connector connected to it. Above the front end of the shelf, corresponding to the outer wall of the ventilation component, an air supply pipe is provided that is connected to and detachably connected to the second quick connector. The rear end of the outer wall of the pot body is equipped with a pressure gauge and a pressure relief valve connected to it.

[0009] By adopting the above technical solution, during use, first connect the boiler's steam pipe to the air blowing assembly via the first quick connector, then open the sealing cover and remove the rack from the sliding assembly. The operator places the materials inside the rack, then places the rack back onto the fixed frame. Next, connect the gas supply pipe to the air blowing assembly via the second quick connector, then close the sealing cover, allowing high-temperature, high-pressure steam to be blown into the pot through the air blowing assembly and ventilation assembly. The air blowing assembly sterilizes the materials on the surface of the rack with the high-temperature, high-pressure steam, while the ventilation assembly sterilizes the materials accumulated inside the rack. This internal and external coordination allows the steam to quickly heat and sterilize the materials. During sterilization, the operator can monitor the pressure inside the pot and the progress of sterilization by checking the pressure value on the pressure gauge. After sterilization, open the pressure relief valve to reduce the pressure inside the pot, then open the sealing cover and disconnect the gas supply pipe from the second quick connector to remove the rack from the pot, thus completing the sterilization of the materials.

[0010] A further feature of this invention is that the air blowing assembly includes a first air guide tube, several second air guide tubes arranged in a ring at equal intervals at the lower end of the first air guide tube and all connected thereto, and several air blowing holes respectively opened on the inner wall of the second air guide tubes and arranged at equal intervals.

[0011] By adopting the above technical solution, high-temperature and high-pressure steam can be blown onto the rack quickly and relatively evenly, thereby improving the sterilization effect on the materials inside the rack.

[0012] A further feature of this invention is that the sliding assembly includes a slide rail with openings at both the upper and front ends, a plurality of pulleys rotatably connected to the left and right sides of the inner wall of the slide rail and extending out of their upper openings, and a limiting rod disposed on the outer wall of the slide rail and arranged along its length.

[0013] By adopting the above technical solution, the smoothness of the sliding of the rack can be improved when placing it in the pot and removing it from the pot. The limiting rod can also limit the rack and prevent it from detaching from the sliding component.

[0014] A further feature of this invention is that the shelf includes a fixed frame, a plurality of sliding grooves arranged from bottom to top and opposite to each other on the left and right sides of the inner wall of the fixed frame and along its length, and a carrying frame slidably connected between each pair of opposite sliding grooves and detachably connected thereto.

[0015] The present invention is further configured as follows: the ventilation component includes multiple positioning slide rods arranged in an array, a fixed mesh plate that is fitted to and slidably connected to the outer wall of the positioning slide rods, a first ventilation pipe that is rectangularly arranged at the lower end of the fixed mesh plate, several second ventilation pipes that are arranged between the left and right sides of the inner wall of the first ventilation pipe and communicate with it, and conical air nozzles that are respectively arranged at the bottom of the first ventilation pipe and the second ventilation pipe and communicate with them. The outer wall of each air nozzle is provided with several through holes, and each pair of adjacent air nozzles are staggered.

[0016] By adopting the above technical solution, the air nozzle of the ventilation component can be extended into the material, so that steam can start sterilization inside the material. In addition, by cooperating with the air blowing component, the sterilization efficiency of the material can be improved and the material can be heated evenly to a certain extent.

[0017] A further feature of this invention is that each fixed mesh plate has a return spring fitted over the outer wall of the corresponding positioning slide rod at its lower end.

[0018] By adopting the above technical solution, when the material needs to be removed from the fixed frame after sterilization, the return spring can keep the ventilation component away from the corresponding loading frame, making it easier to remove the loading frame.

[0019] A further feature of this invention is that the front end of the fixed frame is provided with a baffle that is sealed and connected to the bottom of the pot body, and a drain valve communicating with the rear end of the baffle is installed at the front end of the bottom of the pot body.

[0020] By adopting the above technical solution, not only can the water generated during the sterilization process be collected at the bottom of the pot for easy drainage, but it can also prevent hot water from flowing directly out of the pot opening when the staff opens the sealed lid, thus preventing scalding of the staff.

[0021] In summary, this utility model has the following beneficial effects:

[0022] Firstly, this utility model can sterilize materials with steam, and during the sterilization process, it can not only ensure the sterilization effect on the materials, but also achieve simultaneous heat sterilization of the materials piled on the rack, thus improving the sterilization effect on the materials.

[0023] Secondly, the combination of the blowing component and the ventilation component of this utility model can not only achieve synchronous heating of the inside and outside of the material, so that the material is heated evenly and the sterilization effect is improved, but also improve the working efficiency of sterilizing the material.

[0024] Thirdly, the baffle and drain valve of this utility model not only allow the water generated during the sterilization process to collect at the bottom of the pot body for easy drainage, but also prevent hot water from flowing directly out of the pot body when the staff opens the sealing cover, thus preventing scalding of the staff.

[0035] Example, refer to Figure 1-5 A steam sterilizer includes a pot body 1 with an open front end and heat preservation function, and a sealing cover 11 hinged to and sealed to the open front end of the pot body 1. The pot body 1 is inclined downward from back to front. An air blowing assembly 2 is provided on the inner wall of the pot body 1, with one end extending out of the rear end of its outer wall. The air blowing assembly 2 includes a first air guide pipe 21, a number of second air guide pipes 22 arranged in a ring at equal intervals at the lower end of the first air guide pipe 21 and all connected to it, and a number of air blowing holes 23 respectively opened on the inner wall of the second air guide pipes 22 and arranged at equal intervals. A first quick connector 24 is installed at the end of the first air guide pipe 21 that extends out of the outer wall of the pot body 1 and is connected to it. A gap is left between the bottom of each second air guide pipe 22 and the bottom of the inner wall of the pot body 1.

[0036] A fixed frame 3 is provided on the inner wall of the pot body 1 near its lower end. A baffle 35 is provided at the front end of the fixed frame 3 and is sealed to the bottom of the pot body 1. A drain valve 36 is installed at the front end of the bottom of the pot body 1 and connected to the rear end of the baffle 35. A sliding component 31 is provided on the left and right sides of the upper end of the fixed frame 3 along its length. The sliding component 31 includes a slide rail 32 with an opening at the upper end and the front end, several pulleys 33 rotatably connected to the left and right sides of the inner wall of the slide rail 32 and extending out of their upper openings, and a limiting rod 34 provided on one side of the outer wall of the slide rail 32 along its length. A detachable rack 4 is slidably connected to the upper end of the two sliding components 31. The rack 4 includes a fixed frame 41, multiple slide grooves 42 that are evenly distributed from bottom to top and are opened opposite each other on the left and right sides of the inner wall of the fixed frame 41 along its length, and a rack 43 that is slidably connected between each pair of opposite slide grooves 42 and is detachably connected to them.

[0037] On the left and right sides of the inner wall of the fixed frame 41, ventilation components 5 are slidably connected to the upper ends of every two oppositely arranged sliding grooves 42. The ventilation components 5 include multiple positioning slide rods 51 arranged in an array, a fixed mesh plate 52 that is fitted to and slidably connected to the outer wall of the positioning slide rods 51, a first ventilation pipe 53 that is rectangularly arranged at the lower end of the fixed mesh plate 52, several second ventilation pipes 54 that are arranged between the left and right sides of the inner wall of the first ventilation pipe 53 and communicate with it, and conical air nozzles 55 that are respectively arranged at the bottom of the first ventilation pipe 53 and the second ventilation pipe 54 and communicate with them. The outer wall of each air nozzle 55 has several through holes (not shown in the figure), and every two adjacent air nozzles 55 are staggered front and back.

[0038] Each fixed mesh plate 52 has a return spring 56 at its lower end that is sleeved on the outer wall of the corresponding positioning slide rod 51. The rear ends of the first vent pipes 53 of each pair of adjacent venting components 5 are connected by a flexible connecting pipe 6. The front end of the first air guide pipe 21 is equipped with a second quick connector 61 that is connected to it. Above the front end of the fixed frame 41, on the outer wall of the first vent pipe 53 of the venting component 5, there is a gas supply pipe 62 that is connected to the second quick connector 61 and is detachably connected to it. The rear end of the outer wall of the pot body 1 is equipped with a pressure gauge 12 and a pressure relief valve 13 that are connected to it.

[0039] Usage: When using, first connect the steam pipe of the boiler to the first air guide pipe 21 of the air blowing assembly 2 through the first quick connector 24. Then open the sealing cover 11 and remove the load rack 4 from the sliding assembly 31. Next, the operator takes the load frame 43 out of the slide groove 42 on the fixed frame 41 and places the material in it. Then put the load frame 43 back on the fixed frame 41 and press the fixed mesh plate 52 to compress the return spring 56 and slide it down along the positioning slide rod 51 so that the air nozzle 55 is placed into the material. Then fix both ends of the front end of the air blowing assembly 5. Then place the load rack 4 on the fixed pipe and the sliding assembly 31. The bottom of the fixed frame 41 contacts the pulley 33 on the slide rail 32 to improve the smoothness of its sliding. At the same time, the limiting rod 34 can limit the fixed frame 3 to prevent the fixed frame 41 from separating from the pulley 33 during the sliding process. Then connect the air supply pipe 62 to the first air guide pipe 21 of the air blowing assembly 2 through the second quick connector 61.

[0040] Then, the sealing cover 11 is closed, allowing high-temperature, high-pressure steam to be blown onto the material through the air blowing hole 23 on the second air guide pipe 22 and to sterilize its surface. At the same time, the steam in the first air vent 53 and the second air vent 54 will be blown into the interior of the material through the air blowing nozzle 55 and the through hole on its outer wall to sterilize the accumulated material. The air blowing component 2 and the air ventilation component 5, through their internal and external cooperation, allow the steam to quickly heat and sterilize the material. During the sterilization process, the staff can use the air pressure value detected by the pressure gauge 12 to know the air pressure inside the pot 1 and the progress and effect of sterilization.

[0041] After sterilization, open the pressure relief valve 13 to reduce the air pressure inside the pot 1, and then open the sealing cover 11. The water droplets generated inside the pot 1 during sterilization and pressure relief will collect at the bottom and flow to the baffle 35 to prevent the high-temperature water from flowing directly out of the opening of the pot 1, thus preventing burns to the staff. Then, the staff can remove the air supply pipe 62 from the second quick connector 61 to remove the carrying rack 4 from the pot 1. Then, the support rod can be removed from the fixed mesh plate 52. The return spring 56 can make it move away from the corresponding carrying frame 43. Then, the carrying frame 43 can be removed from the fixed frame 41 to complete the sterilization of the materials. Finally, open the drain valve 36 to drain the water.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that make creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
