Description

Technical Field

[0001] This utility model relates to the field of ceramic casserole technology, specifically a heat-resistant ceramic casserole with a pressure-pressurizing structure. Background Technology

[0002] Ceramic casseroles are cooking utensils made primarily of natural clay or porcelain clay, or using ceramic composite materials. They have good sealing and heat retention properties, and allow food to absorb flavors better when stewed, making them widely used in modern society.

[0003] A search revealed a Chinese patent for a heat-resistant ceramic casserole with a pressure-pressurized structure, publication number CN222285218U. The casserole includes a metal pot body with a stepped surface axially formed at the upper opening. The top surface of the stepped surface abuts against a sealing ring, and the top surface of the sealing ring is fixedly connected to a pot lid, which is disposed within the stepped surface.

[0004] The aforementioned device connects the lid and the metal pot body through guide grooves, arc grooves, arc blocks, stepped surfaces, and counterweight rings, thereby increasing the airtightness of the metal pot body and allowing the food inside the pot to be cooked in a sealed, high-pressure environment, which in turn accelerates the cooking speed of the food inside the pot.

[0005] However, its structure is relatively simple. The ceramic inner pot is fixed in the metal pot body, and the connection lacks sealing measures. Soup and other food liquids can easily seep into the connection layer, making it difficult to clean and affecting the hygiene of use. In addition, when boiling, soup and foam can easily overflow, which may generate a large mechanical impact and cause significant damage to the edge of the pot. Utility Model Content

[0006] The purpose of this invention is to provide a heat-resistant ceramic casserole with a pressure-pressurizing structure, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A heat-resistant ceramic casserole with a pressure structure includes a metal pot body, with handles provided at the upper positions of both the front and rear ends of the metal pot body, and a ceramic inner liner provided inside the metal pot body. Stepped ring block two and stepped ring block one are sequentially fixedly connected to the upper position of the outer ring of the ceramic inner liner.

[0009] The stepped ring block one, stepped ring block two, and ceramic inner liner are arranged in a stepped shape. The upper part of the interior of the metal pot body is provided with a stepped groove that adapts to and matches the stepped ring block one and stepped ring block two. The outer ring of the stepped ring block one and stepped ring block two is fitted with a stepped corrugated skirt. One end of the stepped corrugated skirt extends into the ceramic inner liner and is connected to a silicone skirt. The silicone skirt is arranged in a circular shape. The upper part of the interior of the metal pot body is detachably installed with a pot lid. The lower part of the outer ring of the pot lid is provided with several rotating locking blocks, and the interior of the metal pot body is provided with an anti-dislodgement groove that adapts to and matches the rotating locking blocks.

[0010] Preferably, a push rod is threadedly installed at the center of the top of the pot lid, and an exhaust port is provided at one side of the top of the pot lid. The bottom end of the push rod is rotatably connected to a sealing gasket that is compatible with the exhaust port.

[0011] Preferably, the sealing gasket, silicone skirt, and stepped corrugated skirt are all made of high tear-resistant liquid silicone, and the bottom inner side of the pot lid is in contact with the top surface of the stepped corrugated skirt located at the second stepped ring block.

[0012] Preferably, the top surface of the silicone skirt and the stepped corrugated skirt is provided with a drainage block at the center of the front and rear ends, and the drainage block is designed in the shape of an outwardly protruding "eagle beak notch".

[0013] Preferably, the ceramic inner liner and the metal pot body are detachably connected, and the end of the stepped corrugated skirt away from the silicone skirt extends into the connection between the stepped ring block one, the stepped ring block two, and the stepped groove.

[0014] Preferably, a handle is provided on the top of the pot lid on the side away from the vent, and a throttle is fixedly connected to the top of the push rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up silicone skirts, stepped corrugated skirts, stepped ring block one, and stepped ring block two in cooperation with each other, and by setting detachable silicone skirts and stepped corrugated skirts on the ceramic inner pot, can form multiple concave and convex stepped seals at the connection with the metal pot body, which can reduce the probability of soup seeping into the connection between the metal pot body and the ceramic inner pot. At the same time, the connection can be detached for easy subsequent cleaning.

[0017] By combining silicone skirts, stepped corrugated skirts, a ceramic inner pot, and a metal pot body, the elasticity of the silicone skirts and stepped corrugated skirts can reduce vibrations caused by thermal expansion. When boiling soup overflows, it is first slowed down step by step by the stepped grooves formed by stepped ring block one and stepped ring block two. At the same time, the lid covers the top surface of stepped ring block two for secondary sealing. The boiling soup foam will flow back into the ceramic inner pot along the steps and will not directly contact the connection between the metal pot body and the ceramic inner pot, thus reducing damage to the pot rim.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 A heat-resistant ceramic casserole with a pressurized structure includes a metal pot body 1, with handles 2 at the upper positions of both the front and rear ends of the metal pot body 1, and a ceramic inner liner 3 inside the metal pot body 1. Stepped ring block 2 7 and stepped ring block 1 6 are sequentially fixedly connected to the upper position of the outer ring of the ceramic inner liner 3.

[0025] See Figure 2 and Figure 3Furthermore, it is found that the stepped ring block 1 6, stepped ring block 2 7, and ceramic inner liner 3 are combined in a stepped shape. The upper part of the interior of the metal pot body 1 has a stepped groove that adapts to and matches the stepped ring block 1 6 and stepped ring block 2 7. The outer ring of the stepped ring block 1 6 and stepped ring block 2 7 is fitted with a stepped corrugated skirt 5. One end of the stepped corrugated skirt 5 extends into the ceramic inner liner 3 and is connected to a silicone skirt 4, which is circularly arranged. A pot lid 8 is detachably installed at the upper part of the interior of the metal pot body 1. The lower outer ring of the lid 8 has several rotating blocks 9, and the interior of the metal pot body 1 has an anti-dislodgement groove that is compatible with the rotating blocks 9. A push rod 12 is threadedly installed at the center of the top of the lid 8. An exhaust port 10 is located on one side of the top of the lid 8. A sealing gasket 11 that is compatible with the exhaust port 10 is rotatably connected to the bottom of the push rod 12. A handle 13 is located on the side of the top of the lid 8 away from the exhaust port 10. A rotating handle is fixedly connected to the top of the push rod 12.

[0026] Specifically, during food heating, the outer ring of the ceramic inner pot 3 is fixedly connected with stepped ring block 1 6 and stepped ring block 2 7. Through the ceramic inner pot 3, stepped ring block 1 6, and stepped ring block 2 7 working in conjunction with the stepped grooves within the ceramic inner pot 3, multiple stepped sealing structures can be formed. Furthermore, the ceramic inner pot 3, stepped ring block 1 6, and stepped ring block 2 7 are fitted with silicone skirts 4 and stepped corrugated skirts 5. Thus, after the ceramic inner pot 3 is installed inside the metal pot body 1, the multiple stepped sealing structures provide a rigid positioning effect. The silicone skirt 4 and the stepped corrugated skirt 5 provide elastic filling. The two complement each other, making it difficult for soup to seep into the connection between the metal pot body 1 and the ceramic inner pot 3. At the same time, the metal pot body 1 and the ceramic inner pot 3 are not connected as a whole, so they can be disassembled. When cleaning is required, the silicone skirt 4 can be pulled upwards to lift the ceramic inner pot 3 with the lid 8 removed. After the ceramic inner pot 3 is separated from the ceramic inner pot 3 by a large part, people can directly hold the outside of the ceramic inner pot 3 to remove it.

[0027] Example 2

[0028] See Figure 2 Furthermore, based on Example 1, the sealing gasket 11, silicone skirt 4, and stepped corrugated skirt 5 are all made of high tear-resistant liquid silicone. The bottom of the pot lid 8 is close to the top surface of the stepped corrugated skirt 5 located at the stepped ring block 2 7. The silicone skirt 4 and the stepped corrugated skirt 5 are both provided with a drainage block 14 at the center of the front and rear ends of the top surface. The drainage block 14 is shaped like an outwardly protruding "eagle beak notch". The ceramic inner liner 3 and the metal pot body 1 are detachably connected. The end of the stepped corrugated skirt 5 away from the silicone skirt 4 extends into the connection between the stepped ring block 1 6, the stepped ring block 2 7, and the stepped groove.

[0029] Specifically, by filling the connection between the metal pot body 1 and the ceramic inner liner 3 with silicone skirt 4 and stepped corrugated skirt 5, a certain amount of thermal expansion difference and vibration can be absorbed. At the same time, when the lid 8 is placed on the metal pot body 1, its bottom edge will fit with the stepped ring block 6, and the stepped corrugated skirt 5 is provided at the fitting point. At this time, the lid 8, stepped ring block 6, stepped corrugated skirt 5, and stepped ring block 7 work together to slow down the boiling soup step by step by multiple stepped structures and guide it to slide down. Then, the silicone skirt 4 elastically seals it, which can effectively reduce the impact force when the soup boils, so as to prevent damage to the edge of the pot. When pouring soup, the metal pot body 1 can be tilted towards the diversion block 14. The diversion block 14 can guide the soup to flow out in a concentrated manner, thereby forming a stable water column and preventing the soup from flowing randomly along the outer wall.

[0030] In actual operation, the steps of heating food through the metal pot body 1 in the existing technology will not be repeated here. When the food is heated, the outer ring of the ceramic inner pot 3 is fixedly connected with stepped ring block 1 6 and stepped ring block 2 7. Through the ceramic inner pot 3, stepped ring block 1 6 and stepped ring block 2 7, and the stepped groove set in the ceramic inner pot 3, multiple stepped sealing structures can be formed.

[0031] Furthermore, the ceramic inner pot 3, the stepped ring block 1 6, and the stepped ring block 2 7 are fitted with silicone skirts 4 and stepped corrugated skirts 5. Thus, after the ceramic inner pot 3 is installed inside the metal pot body 1, it can provide rigid positioning through multiple stepped sealing structures. The silicone skirts 4 and stepped corrugated skirts 5 can provide elastic filling. The two complement each other, making it difficult for soup to seep into the connection between the metal pot body 1 and the ceramic inner pot 3.

[0032] Meanwhile, the metal pot body 1 and the ceramic inner pot 3 are not connected as a single piece, which can maintain the function of being detachable. When cleaning is required, the silicone skirt 4 can be pulled upwards directly after the pot lid 8 is removed to lift the ceramic inner pot 3. After the ceramic inner pot 3 is separated from the ceramic inner pot 3 by a large part, the person can directly hold the outside of the ceramic inner pot 3 to remove the ceramic inner pot 3.

[0033] By filling the connection between the metal pot body 1 and the ceramic inner liner 3 with silicone skirt 4 and stepped corrugated skirt 5, a certain amount of thermal expansion difference and vibration can be absorbed. At the same time, when the lid 8 is placed on the metal pot body 1, its bottom edge will fit with the stepped ring block 6, and the stepped corrugated skirt 5 is provided at the fitting point. At this time, the lid 8, stepped ring block 6, stepped corrugated skirt 5, and stepped ring block 7 work together to slow down the boiling soup step by step by multiple stepped structures and guide it to slide down. Then, the silicone skirt 4 elastically seals it, which can effectively reduce the impact force when the soup boils, so as to prevent damage to the edge of the pot. When pouring soup, the metal pot body 1 can be tilted towards the diversion block 14, which can guide the soup to flow out in a concentrated manner, thereby forming a stable water column and preventing the soup from flowing randomly along the outer wall.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
