Description

Technical Field

[0001] This utility model relates to the field of enamel pot technology, and in particular to an energy-saving and heat-resistant cast iron enamel pot. Background Technology

[0002] Cast iron enamel cookware has become a popular choice in modern kitchens due to its excellent heat retention, heat preservation, and aesthetic appeal. Traditional cast iron enamel cookware typically consists of a pot body and a lid, with the lid securing itself to the pot body by its own weight to achieve a basic seal.

[0003] In cooking modes that require prolonged heating, such as stewing, boiling, and braising, a large amount of water vapor is generated inside the pot, causing a significant increase in internal pressure. When the internal pressure accumulates to a certain level, the high-pressure airflow generates an upward force. Under the action of this force, the heavy pot lid is momentarily and slightly lifted, detaching from the close contact with the pot body and shifting slightly away from the pot body. This phenomenon can cause intermittent, imperceptible gaps between the pot body and the pot lid.

[0004] This causes high-temperature steam and heat to continuously leak through the gaps, resulting in temperature fluctuations and drops inside the pot. In order to maintain the required cooking temperature, the heat source needs to work more frequently or at higher power to compensate for the lost heat, which directly leads to increased energy consumption. Utility Model Content

[0005] In view of the inherent shortcomings in the sealing performance of existing cast iron enamel pots, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an energy-saving and heat-resistant cast iron enamel pot, which aims to actively lock the lid and the pot body together, overcoming the defects of traditional gravity sealing.

[0007] To solve the above technical problems, this utility model provides the following technical solution: an energy-saving and anti-scalding cast iron enamel pot, including a pot body and a pot lid, wherein heat-insulating handle brackets are installed on both sides of the pot body near the end of the pot lid, and a locking mechanism is installed in the middle of the top of the pot body, and the two locking ends of the locking mechanism are respectively connected to the heat-insulating handle brackets. The locking mechanism includes a crossbeam, with two heat-insulating support plates installed at the bottom of the crossbeam. The bottom ends of the heat-insulating support plates are fixed to the pot lid. L-shaped connecting plates are provided on both sides of the crossbeam, and the two L-shaped connecting plates move towards the center or to the sides at the same time. A hanging strip that engages with the heat-insulating handle bracket is installed on the bottom end of the L-shaped connecting plate and on the side away from the crossbeam.

[0008] As an improved technical solution, a transmission block is provided in the middle of one side of the crossbeam for the transverse end of the L-shaped connecting plate to pass through. Limiting cavities connected to the transverse movement cavity are provided at the front and rear ends of the crossbeam. A linkage bar is integrally formed at one end of the L-shaped connecting plate located inside the transverse movement cavity. Transmission blocks that slide laterally inside the limiting cavity are integrally formed at both ends of the linkage bar.

[0009] As an improved technical solution, a light rod is fixed inside one of the limiting cavities, and a double-ended screw is rotatably installed inside the other limiting cavity. A threaded hole for threaded connection with the double-ended screw is opened on the transmission block near the side of the double-ended screw.

[0010] As an improved technical solution, drive shafts are rotatably mounted on both sides of one end face of the crossbeam. A bevel gear transmission component is installed between the end of the drive shaft located inside the limiting cavity and the light rod. The bevel gear transmission component consists of two meshing bevel gears.

[0011] As an improved technical solution, a raised edge is fixed around the edge of the pot lid, and a connecting platform is provided at the center of the pot lid. A lifting handle is fixed to the end of the connecting platform away from the pot body by bolts.

[0012] As an improved technical solution, the inner edge of the pot lid is provided with an upper concave cavity, the end face of the pot lid away from the pot body is provided with a lower concave cavity, and several conical heads are fixed to the top of the inner wall of the pot lid.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, the upper and lower concave cavities form a specific concave cavity circuit, and the conical head facilitates the liquefaction and return of water vapor to the interior of the pot, achieving self-circulation.

[0014] 2. This utility model uses a locking mechanism to lock the pot body and the lid together, resisting the airflow force generated by the increased pressure of the pot body. This prevents the lid from being lifted and creating gaps, effectively preventing the leakage of high-temperature steam and heat, reducing the energy consumption required by the heat source to maintain the temperature, achieving excellent energy-saving effect, and facilitating the formation of a stable micro-pressure environment in the pot body. This not only helps to shorten cooking time, but also allows heat to penetrate evenly and deeply into the food. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention, which provides an energy-saving and heat-resistant cast iron enamel pot. This energy-saving and heat-resistant cast iron enamel pot includes a pot body 1 and a pot lid 2. Heat-insulating handle brackets 4 are installed on both sides of the pot body 1 near the end of the pot lid 2. A locking mechanism 3 is installed in the middle of the top of the pot body 1, and the two locking ends of the locking mechanism 3 are respectively connected to the heat-insulating handle brackets 4. The locking mechanism 3 includes a crossbeam 31, and the middle of the crossbeam 31 is provided with a central hole through which the lifting handle 8 passes. Two heat insulation support plates 32 are installed at the bottom of the crossbeam 31, and the bottom end of the heat insulation support plate 32 is fixed on the pot lid 2. L-shaped connecting plates 33 are provided on both sides of the crossbeam 31, and the two L-shaped connecting plates 33 move towards the middle or to the sides at the same time. The bottom end of the L-shaped connecting plate 33 and the side away from the crossbeam 31 are provided with a hanging strip 34 that is engaged with the heat insulation handle bracket 4.

[0023] The locking mechanism 3 secures the pot body 1 and lid 2 together, resisting the airflow force generated by the increased pressure on the pot body 1. This prevents the lid 2 from being lifted and creating gaps, effectively preventing the leakage of high-temperature steam and heat. This reduces the energy consumption required by the heat source to maintain the temperature, achieving excellent energy-saving effects. Furthermore, it helps the pot body 1 form a stable micro-pressure environment, which not only helps shorten cooking time but also allows heat to penetrate evenly and deeply into the food. The tight locking structure prevents steam from accidentally escaping from around the lid during cooking, reducing the risk of burns from high-temperature steam and enhancing safety. A transmission block 37 is provided in the middle of one side of the crossbeam 31 for the transverse end of the L-shaped connecting plate 33 to pass through. The front and rear ends of the crossbeam 31 are provided with limiting cavities 38 that communicate with the transverse moving cavity 35. The height of the limiting cavity 38 is greater than the height of the transverse moving cavity 35. One end of the L-shaped connecting plate 33 located inside the transverse moving cavity 35 is integrally formed with a linkage bar 36. The two ends of the linkage bar 36 are located inside the two limiting cavities 38 respectively. The two ends of the linkage bar 36 are integrally formed with a transmission block 37 that slides laterally inside the limiting cavity 38.

[0024] A guide rod 39 is fixed inside one limiting cavity 38, and a sliding hole for the guide rod 39 to pass through is provided on the transmission block 37 near the guide rod 39. A double-ended screw 310 is rotatably installed inside the other limiting cavity 38, and a threaded hole for threaded connection with the double-ended screw 310 is provided on the transmission block 37 near the double-ended screw 310. The locking state between the pot body 1 and the pot lid 2 is driven by the threaded transmission, which facilitates quick switching between the locking states of the pot body 1 and the pot lid 2.

[0025] Both sides of one end face of the crossbeam 31 are rotatably mounted with drive shafts 312, and a knob is installed at the end of the drive shaft 312 located outside the crossbeam 31. A bevel gear transmission component 311 is installed between the end of the drive shaft 312 located inside the limiting cavity 38 and the light rod 39. The bevel gear transmission component 311 is composed of two meshing bevel gears.

[0026] A raised edge 5 is fixed around the edge of the pot lid 2, and a connecting platform 9 is provided at the center of the pot lid 2. A lifting handle 8 is fixed to the end of the connecting platform 9 away from the pot body 1 by bolts.

[0027] The inner edge of the pot lid 2 is provided with an upper concave cavity 6, and the end face of the pot lid 2 away from the pot body 1 is provided with a lower concave cavity 7. Several conical heads 10 are fixed on the top of the inner wall of the pot lid 2. The upper concave cavity 6 and the lower concave cavity 7 form a specific concave cavity circuit. Through the setting of the conical heads 10, it is more conducive to the liquefaction of water vapor and its return to the interior of the pot body 1, so as to achieve self-circulation.

[0028] The working principle of this utility model is as follows: Drive shaft 312 rotates, and under the transmission action of bevel gear transmission component 311, drive shaft 312 to drive rod 39 to rotate. Under the threaded transmission action of threaded hole on transmission block 37 and double-headed screw 310, the forward and reverse rotation of double-headed screw 310 synchronously drives the two L-shaped connecting plates 33 to move towards the center or sides. When it is necessary to lock the pot body 1 and pot lid 2, drive the two L-shaped connecting plates 33 to move towards the sides. Hanging strips 34 on the two L-shaped connecting plates 33 are locked at the bottom of heat-insulating handle bracket 4. The pot body 1 and pot lid 2 are detachably locked together by the locking between hanging strips 34 and heat-insulating handle bracket 4.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
