Description

Technical Field

[0001] This utility model belongs to the field of cookware technology, and mainly relates to a commercially available split-type soup pot with high-efficiency heat transfer. Background Technology

[0002] In commercial cookware used in restaurants, soup pots typically employ a water bath heating structure for stewing soup in order to preserve the original flavor of the ingredients. Soup pots generally have a split structure, consisting of a detachable inner pot and a pot body, with water added between the inner pot and the pot body as a temperature conduction medium to ensure even heating of the inner pot. However, in traditional commercial soup pots, the heating medium (water) is prone to evaporation during use, requiring frequent manual replenishment of water, which affects the convenience of use. Utility Model Content

[0003] The purpose of this invention is to design a commercially available split-type soup pot with high-efficiency heat transfer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a pot body and an inner liner placed inside the pot body. A water bath chamber is provided between the side wall of the inner liner and the inner wall of the pot body. A water level sensor is provided at the top of the water bath chamber. A flange is provided at the top of the pot body. A cooling chamber connected to a water supply pump is provided inside the flange. The cooling chamber is connected to the water bath chamber through a flow channel. A one-way valve is provided inside the flow channel. Both the water level sensor and the water supply pump are connected to a controller.

[0005] Furthermore, a water inlet pipe communicating with the cooling chamber is fixedly connected to the bottom of the rim, and a valve is provided on the water inlet pipe. The outlet pipe of the water supply pump is connected to the water inlet pipe through a quick-release connector, and a partition is provided inside the cooling chamber.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Example: Please refer to Figure 1-4 A commercially available split-type soup pot with high-efficiency heat transfer includes a pot body 4 and an inner liner 2 placed inside the pot body 4. A water bath chamber 10 is provided between the side wall of the inner liner 2 and the inner wall of the pot body 4. A water level sensor 16 is provided on the top of the water bath chamber 10. A rim 3 is provided on the top of the pot body 4. A cooling chamber 9 connected to a water supply pump is provided inside the rim 3. The cooling chamber 9 is connected to the water bath chamber 10 through a flow channel 15. A one-way valve 14 is provided inside the flow channel 15. The water level sensor 16 and the water supply pump are both connected to a controller. The water supply pump is connected to a water supply pipe, such as a common water storage tank, or more directly, the water supply pump's suction pipe can be connected to a faucet. Therefore, when the water level sensor 16 senses that the water level inside the pot body 4 is lower than a threshold, it sends a signal to the controller, which then starts the water supply pump to replenish water to an appropriate level, preventing the need for frequent manual water replenishment due to easy evaporation and improving the convenience of the soup pot.

[0023] In the above process, there are two water level sensors 16, which are used to provide feedback on the upper and lower limits of the water level, respectively. In addition, the soup pot is also equipped with a buzzer. When the water level sensor 16 at the lower limit sends a signal to the controller, the delayed relay will start timing. If the water level sensor 16 at the upper limit does not send a signal to the controller within the specified time, the relay will connect the buzzer circuit and disconnect the heating function of the soup pot, thereby playing an alarm role and preventing the soup pot from dry burning due to damage to the water supply pump or insufficient water supply.

[0024] Furthermore, the arrangement of water flowing into the cooling chamber 9 inside the rim 3 before flowing into the water bath chamber 10 facilitates the cooling effect on the rim 3, preventing overheating and making it easier for the operator to move the pot 4 after heating. The bottom of the rim 3 has a groove 13 for easy lifting. The water inlet pipe is located inside the groove 13, making the pot structure more compact. The flow channel 15 includes a first flow channel 15 connected to the cooling chamber 9 and a second flow channel 15 connected to the first flow channel 15 and inclined downwards. The one-way valve 14 is located inside the first flow channel 15, so that water is injected into the water bath chamber 10 at an inclined downwards. In addition, the top of the pot 4 is equipped with a pressure relief valve to prevent the internal pressure of the water bath chamber 10 from becoming too high.

[0025] The bottom of the rim 3 is fixedly connected to a water inlet pipe that communicates with the cooling chamber 9. The water inlet pipe is equipped with a valve. The outlet pipe of the water supply pump is connected to the water inlet pipe through a quick-release connector. The interior of the cooling chamber 9 is equipped with a partition. The water inlet pipe and the flow channel 15 are located on both sides of the partition. The quick-release connector is a common connector used for water pipe splicing, which will not be described in detail here. In addition, the outlet pipe of the water supply pump can be a flexible hose with an inner diameter smaller than that of the water inlet pipe. The water inlet pipe can also be quickly installed by deforming the flexible hose and inserting it into the flexible hose. The valve is connected to the controller. The valve is normally closed. The controller will open the valve when water needs to be added.

[0026] In other embodiments, an electric heating tube 8 is provided at the bottom of the inner pot body 4, and a ring-shaped electric heating plate 5 is provided on the inner side wall of the pot body 4, so as to achieve rapid heating of water; while the bottom of the inner pot 2 is provided with several ring-shaped fins 7, and the side wall of the inner pot 2 is provided with several ring-shaped spiral fins 6, thereby increasing the contact area between the inner pot 2 and the hot water, thereby improving the heat transfer efficiency between the inner pot 2 and the hot water, thus ensuring the efficient heat transfer of the soup pot.

[0027] In other embodiments, the top of the inner liner 2 is also provided with a positioning platform 17, which cooperates with the through hole at the top of the pot body 4. The diameter of the positioning platform 17 is larger than the maximum diameter of the spiral fins 6 to prevent the gap between the inner liner 2 and the through hole from being too large due to the installation of the spiral fins 6, which would make it difficult for the inner liner 2 to be heated in the water bath. The bottom of the positioning platform 17 is provided with a chamfer 18 to facilitate the installation of the inner liner 2. The top of the inner liner 2 is provided with a limiting platform 11, and a recessed platform 19 is provided on the limiting platform 11. A permanent magnet is embedded in the recessed platform 19. The cover plate 1 is embedded in the recessed platform 19 under the attraction of the permanent magnet, which helps to prevent the cover plate 1 from falling off. The top of the pot body 4 is provided with a support platform 12, and the limiting platform 11 abuts against the support platform 12. There is a gap between the limiting platform 11 and the top of the pot body 4 to facilitate the removal of the inner liner 2.

[0028] Working principle: When the water level sensor 16 senses that the water level inside the pot 4 is lower than the threshold, it sends a signal to the controller, which then starts the water supply pump to replenish water. The water will flow into the cooling chamber 9 through the water inlet pipe, and after circulating once in the cooling chamber 9, it will enter the water bath chamber 10 through the flow channel 15, thereby replenishing water and preventing the need for frequent manual water replenishment due to easy evaporation of water, thus improving the convenience of the soup pot.
