Description

Technical Field

[0001] The utility model relates to the technical field of cooking pots, in particular to a high-temperature and high-pressure cooking pot. Background Art

[0002] The high-temperature and high-pressure cooking pot uses steam at a certain pressure as the heat source (electric heating, gas heating, electromagnetic heating, etc. can also be used). It achieves rapid cooking through internal high pressure, which has the advantages of shortening the cooking time, saving heat source, and improving production efficiency.

[0003] The rotating shaft of the existing steamer is directly welded to the pot body, so that the heat source covering the outer periphery of the steamer cannot cover the part where the rotating shaft and the steamer are welded, resulting in a heating blind spot in the steamer. The heating blind spot of the high-temperature and high-pressure steamer will cause its heating temperature to be uneven. Summary of the Invention

[0004] The utility model aims to provide a high-temperature and high-pressure cooking pot, which can achieve uniform heating of the cooking pot.

[0005] In order to achieve the above purpose, the utility model provides a high-temperature and high-pressure cooking pot, the specific implementation scheme is as follows:

[0006] A high-temperature and high-pressure cooking pot, comprising:

[0007] Sealed bottom cover;

[0008] The reaction pot body is installed on the sealed bottom cover, and a heating plate is sleeved on the outer peripheral wall;

[0009] A sealing top cover is installed on the top of the reaction pot; and

[0010] Install vertical plates, which are arranged on both sides of the reaction pot body, with the top ends connected to the sealing top cover and the bottom ends connected to the sealing bottom cover;

[0011] The rotating shaft is arranged on a side of the mounting vertical plate away from the reaction pot body, and the two rotating shafts are coaxial.

[0012] The utility model provides a high-temperature and high-pressure cooking pot. Compared with the prior art, a sealed top cover is provided on the top of the reaction pot body, a sealed bottom cover is provided on the bottom, mounting vertical plates are provided on both sides of the reaction pot body between the sealed top cover and the sealed bottom cover, and the mounting vertical plates are used to connect the rotating shaft, so that the rotation of the reaction pot body is driven by the rotating shaft to drive the mounting vertical plates to rotate the sealed top cover and the sealed bottom cover. Compared with the prior art in which the rotating shaft is directly welded to the reaction pot body, the rotating shaft of the utility model is connected to the mounting vertical plates provided outside the reaction pot body, so that the heating plate can completely cover the outer peripheral wall of the reaction pot body, so that the reaction pot body has no heating blind area, and the heating uniformity of the reaction pot body is improved.

[0013] In some embodiments, the rotating shaft is welded to the mounting vertical plate, or the rotating shaft is screwed to the mounting vertical plate.

[0014] The connection and fixation between the rotating shaft and the mounting vertical plate is achieved by welding or screwing, thereby improving the connection stability between the rotating shaft and the mounting vertical plate.

[0015] In some embodiments, when the rotating shaft is screwed to the mounting vertical plate, a step is provided on the end of the rotating shaft, and the step is screwed to the mounting vertical plate.

[0016] By arranging a step on the rotating shaft and screwing the step to the mounting vertical plate, the step serves as a supporting seat of the rotating shaft, thereby improving the connection stability and rotation stability of the rotating shaft.

[0017] In some embodiments, an outer shell is provided between the sealing top cover and the sealing bottom cover, and alignment holes are provided on both sides of the outer shell corresponding to the rotating shaft. The step is provided on the side wall of the outer shell and is screwed to the mounting vertical plate, and the rotating shaft is coaxial with the alignment hole.

[0018] By arranging an outer shell between the sealing top cover and the sealing bottom cover, and utilizing the alignment hole arranged on the outer shell to be coaxial with the rotating shaft and cooperating with the step on the rotating shaft, the connection accuracy between the rotating shaft and the mounting riser is improved.

[0019] In some embodiments, a heat insulation board is provided between the step and the mounting vertical plate, with one end of the heat insulation board in contact with the step and the other end in contact with the mounting vertical plate.

[0020] By arranging a heat insulation board between the step and the mounting vertical board, the heat insulation board can be used to prevent the heat generated during the use of the reaction pot from being transferred to the rotating shaft, causing the rotating shaft to be deformed and damaged due to excessive heat.

[0021] In some embodiments, alignment grooves are provided on both the sealing top cover and the sealing bottom cover, and the top end of the mounting riser is inserted into the alignment groove of the sealing top cover, and the bottom end is inserted into the alignment groove of the sealing bottom cover.

[0022] By arranging alignment grooves on the sealing top cover and the sealing bottom cover, and utilizing the alignment grooves to engage with the top and bottom ends of the mounting risers, the connection convenience and stability of the mounting risers are improved.

[0023] In some embodiments, the rotating shaft is hollow and has a threading hole formed therein, and a threading hole is provided on the mounting vertical plate, and the threading hole matches the threading hole.

[0024] By setting the rotating shaft to be hollow to form a wire threading hole, and setting a wire passing hole matching the wire threading hole on the mounting vertical plate, the wiring of the heating plate can be hidden in the rotating shaft by using the wire threading hole and the wire passing hole, thereby avoiding the corrosion damage caused by liquid leakage generated by long-term use of the reaction pot body when the wiring is directly routed from the outside, thereby saving the maintenance cost of the high-temperature and high-pressure cooking pot.

[0025] In some embodiments, the outer shell comprises:

[0026] a housing top plate, mounted on the sealing top cover;

[0027] a housing bottom plate, mounted on the sealing bottom cover;

[0028] Fixed columns are provided at the four corners of the bottom plate of the housing, with their top ends connected to the top plate of the housing; and

[0029] A fixed side plate is provided between every two adjacent fixed columns, with both sides connected to the fixed columns on the same side;

[0030] The sealant is arranged at the connection between the top plate of the shell and the fixed side plate and the connection between the bottom plate of the shell and the fixed side plate.

[0031] By setting the outer shell to be composed of an outer shell top plate, an outer shell bottom plate, a fixed column and a fixed side plate, and providing sealant at the connection between the fixed side plate and the outer shell bottom plate and at the connection between the fixed side plate and the outer shell top plate, on the one hand, a sealing effect is achieved. Compared with the structure in the prior art in which two pieces of iron sheets are fastened with a cable tie, the sealing is tighter, thereby avoiding the occurrence of liquid leakage and spraying during the rotation of the reaction pot body; on the other hand, it plays a certain role in heat preservation inside the outer shell.

[0032] In some embodiments, connection blocks are provided on both the top plate and the bottom plate of the housing. The connection block on the top plate of the housing is connected to the sealing top cover, and the connection block on the bottom plate of the housing is connected to the sealing bottom cover.

[0033] By arranging a connecting block between the outer shell top plate and the outer shell bottom plate, the sealing top cover and the sealing bottom cover are connected and fixed to the outer shell using the connecting block, thereby improving the connection stability of the outer shell and the reaction pot body.

[0034] In some embodiments, the heating plate is wrapped with heat-insulating cotton.

[0035] By wrapping the heating plate with thermal insulation cotton, the thermal insulation cotton is utilized to further improve the thermal insulation performance and heat insulating performance of the reaction pot body.

[0036] Based on the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0037] A sealed top cover is provided on the top of the reaction pot body, a sealed bottom cover is provided on the bottom, mounting vertical plates are provided on both sides of the reaction pot body between the sealed top cover and the sealed bottom cover, and the mounting vertical plates are used to connect the rotating shaft, so that the rotation of the reaction pot body is driven by the rotating shaft, and the mounting vertical plates drive the rotation of the sealed top cover and the sealed bottom cover. Compared with the prior art in which the rotating shaft is directly welded to the reaction pot body, the rotating shaft of the utility model is connected to the mounting vertical plates provided outside the reaction pot body, so that the heating plate can completely cover the outer peripheral wall of the reaction pot body, so that there is no heating blind spot in the reaction pot body, thereby improving the heating uniformity of the reaction pot body, and being suitable for high-temperature steaming of new materials in the biomedical field.

[0046] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0047] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0048] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0050] like Figure 1-2 As shown, a high-temperature and high-pressure cooking pot provided in this embodiment includes a machine base 700, on which a groove body 710 is formed for accommodating a reaction pot body 200 of the high-temperature and high-pressure cooking pot, and the reaction pot body 200 can rotate in the groove body 710 without contacting the machine base 700.

[0051] Mounting seats 720 are provided at the top of the base 700 on both sides of the trough body 710. A rotating shaft 500 is provided on each mounting seat 720. The opposite ends of the two rotating shafts 500 extend into the trough body 710 and are connected to the reaction pot body 200 provided in the trough body 710. A motor 730 for driving the rotation thereof is transmission-connected to one of the rotating shafts 500.

[0052] The two rotating shafts 500 are preferably coaxial, which can maintain the rotation balance of the reaction pot 200 driven by the motor 730 and the rotating shafts 500 to a certain extent. The reaction pot 200 rotates 0-360 degrees in the circumferential direction of the rotating shafts 500.

[0053] Combine Figure 3-5 As shown, a heating plate 210 is sleeved on the outer peripheral wall of the reaction pot body 200 to provide a heat source for the reaction pot body 200 .

[0054] A sealing top cover 120 for sealing is provided on the top of the reaction pot body 200, and a sealing bottom cover 110 for sealing is provided on the bottom. Two mounting vertical plates 400 are provided between the sealing bottom cover 110 and the sealing top cover 120 and are located on both sides of the reaction pot body 200. The rotating shaft 500 extends to the end of the trough body 710 and is connected to the mounting vertical plates 400.

[0055] The widths of the sealing top cover 120 and the sealing bottom cover 110 are both greater than the width of the reaction pot body 200 , so that there is a gap between the mounting riser 400 and the reaction pot body 200 , and the heat on the reaction pot body 200 cannot be transferred to the mounting riser 400 .

[0056] Alignment grooves 130 are provided on both the sealing top cover 120 and the sealing bottom cover 110. The top end of the mounting riser 400 is inserted into the alignment groove 130 of the sealing top cover 120, and the bottom end is inserted into the alignment groove 130 of the sealing bottom cover 110, thereby improving the convenience of disassembly and assembly and the connection stability of the mounting riser 400.

[0057] Optionally, the end of the rotating shaft 500 is directly welded to the mounting vertical plate 400 .

[0058] Optionally, the end of the rotating shaft 500 is connected to the mounting vertical plate 400 by screwing.

[0059] When the end of the rotating shaft 500 is connected to the mounting vertical plate 400 by screwing, the reaction pot body 200 is arranged in an outer shell 300, and the end of the rotating shaft 500 is provided with a step 510. The step 510 is integrally formed with the rotating shaft 500. The step 510 directly contacts the outer wall of the outer shell 300 and is connected to the mounting vertical plate 400 arranged inside the outer shell 300 by screws.

[0060] Furthermore, a heat insulating plate 600 may be connected between the step 510 and the mounting riser 400 to effectively prevent the heat of the reaction pot 200 from being transferred to the rotating shaft 500 during use, thereby preventing the rotating shaft 500 from being overheated, deformed, or damaged.

[0061] The rotating shaft 500 connected to the motor 730 can also be set as an internal hollow structure to form a wire hole 520, and a wire hole 410 matching the wire hole 520 can be opened on the mounting vertical plate 400, so that the line passes through the wire hole 520 and the wire hole 410 into the outer shell 300 and is connected to the heating plate 210, avoiding the corrosion damage caused by liquid leakage generated by long-term use of the reaction pot body 200 when the line is directly routed from the outside, thereby saving the maintenance cost of the high-temperature and high-pressure cooking pot.

[0062] The outer shell 300 includes a top plate 310, a bottom plate 320, fixed columns 330, and fixed side plates 340. The top plate 310 is mounted on the sealing top cover 120, and the bottom plate 320 is mounted on the sealing bottom cover 110. The fixed columns 330 are fixed to the four corners of the bottom plate 320, with the tops of the fixed columns 330 connected to the four corners of the top plate 310. A fixed side plate 340 is connected between every two adjacent fixed columns 330, and both sides of each fixed side plate 340 are connected to the fixed columns 330 on the same side. The fixed side plate 340 on the same side as the rotating shaft 500 is connected to the step 510.

[0063] Furthermore, in order to improve the sealing and heat insulation effect of the outer shell 300 , sealants are provided at the connection between the fixed side plate 340 and the outer shell top plate 310 and at the connection between the fixed side plate 340 and the outer shell bottom plate 320 .

[0064] In order to improve the connection stability between the sealing top cover 120 and the sealing bottom cover 110 and the outer shell 300, a plurality of connecting blocks 140 are provided on the outer shell bottom plate 320 and the outer shell top plate 310. The connecting blocks 140 located on the outer shell bottom plate 320 are connected to the sealing bottom cover 110, and the connecting blocks 140 located on the outer shell top plate 310 are connected to the sealing top cover 120.

[0065] In this embodiment, the connecting blocks 140 are preferably disposed at the four corners of the housing bottom plate 320 and the housing top plate 310 .

[0066] The installation cavity formed by the shell top plate 310, the shell bottom plate 320, the fixing column 330 and the fixing side plate 340 accommodates the reaction pot body 200, the heating plate 210 and the installation vertical plate 400, and the outer peripheral wall of the heating plate 210 is wrapped with heat insulation cotton, which can not only improve the heating performance of the reaction pot body 200 but also isolate the heating heat of the reaction pot body 200.

[0067] Compared with the prior art structure of using two pieces of iron sheets fastened with a cable tie, the structure of the outer shell 300 is more tightly sealed, thereby preventing liquid leakage and spraying during the rotation of the reaction pot 200.

[0068] In this embodiment, the outer shell top plate 310 and the outer shell bottom plate 320 are both two arc-shaped plates arranged on the outer peripheral walls of the sealing top cover 120 and the sealing bottom cover 110, thereby improving the connection convenience between the outer shell 300 and the reaction pot body 200, and cooperating with the connecting block 140 to improve the connection stability with the reaction pot body 200.

[0069] A plurality of connecting screws 121 are provided on the top of the sealing top cover 120, and a sealing cover plate 122 is also provided. The sealing cover plate 122 is covered on the sealing top cover 120, and the connecting screws 121 pass through the through holes on the sealing cover plate 122. The sealing cover plate 122 and the sealing top cover 120 are connected and fixed by screwing nuts 123 and the connecting screws 121.

[0070] The working principle of a high-temperature and high-pressure cooking pot provided in this embodiment is as follows: a sealing top cover 120 arranged on the top of the reaction pot body 200 and a sealing bottom cover 110 at the bottom are used to install and fix the mounting vertical plate 400, so that the rotating shaft 500 is installed on the mounting vertical plate 400 and can drive the reaction pot body 200 to rotate on the machine base 700 under the drive of the motor 730. Compared with the prior art in which the rotating shaft 500 is directly welded to the reaction pot body 200, resulting in the heating plate 210 being unable to completely cover the reaction pot body 200 and having a heating blind spot, the technical solution provided in this embodiment can enable the heating plate 210 to completely cover the outer peripheral wall of the reaction pot body 200, so that the reaction pot body 200 does not have a heating blind spot, thereby improving the heating uniformity of the reaction pot body 200, and is suitable for high-temperature cooking of new materials in the biomedical field.

[0071] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
