DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Embodiment: please refer to Figures 1 to 5 A multifunctional energy-saving steam pot stove comprises a stove frame 1, which provides support for other components in the device. The embodiment further comprises a shell 2, an inner container 3, a combustion chamber 4 and a steam cavity 6, which can solve the problem that the amount of generated steam is small in the prior art and multiple external devices such as a steaming box, a steaming tray and a disinfection cabinet cannot be used simultaneously.

[0026] The shell 2 is fixed to the top of the stove frame 1 and is provided with an open upper end, so that an external pot can be taken out or placed. The inner container 3 is fixed in the shell 2, so that the external pot can be placed in the inner container 3. After the external pot is placed in the inner container 3, the gap between the pot and the inner container 3 constitutes a fire passing cavity, and the flame generated by combustion can heat the pot through the fire passing cavity, so that the pot can be used to stir-fry or cook food.

[0027] In the embodiment, the upper end of the inner container 3 is lower than the upper end of the shell 2, and a plurality of smoke outlets 8 are arranged at the upper end of the shell 2 in a circumferential direction at equal intervals. After the external pot is placed in the inner container 3, the upper end edge of the pot is located outside the shell 2, so that the gap between the pot and the shell 2 is in communication with the fire passing cavity, and therefore the smoke in the fire passing cavity can be discharged through the smoke outlets 8.

[0028] In addition, the combustion chamber 4 is fixed to the outer bottom of the shell 2 and communicates with the fire chamber, and a burner 5 is installed in the combustion chamber 4, and the flame formed by the combustion of fuel enters the fire chamber, so that the external pot can be heated. In this embodiment, the fuel can be natural gas, liquefied petroleum gas, vegetable oil fuel, etc., and different types of fuel can be selected flexibly according to actual needs and conditions, which greatly widens the application range, provides more choices for users, and improves the convenience of use.

[0029] In addition, in this embodiment, the outer bottom of the shell 2 is fixed with an air inlet chamber 10 located around the combustion chamber 4, and a plurality of air inlet holes 11 are uniformly distributed along the circumference of the upper end of the combustion chamber 4, and an air blower 12 is installed on the stove rack 1 and communicates with the air inlet chamber 10 through a pipeline. When the air blower 12 works, the external air can enter the combustion chamber 4 through the air inlet chamber 10 and the air inlet hole 11, so that the fuel is mixed with air, and is sent into the fire chamber for combustion, and the flue gas formed after combustion is discharged through the smoke exhaust port 8.

[0030] It is worth mentioning that the steam chamber 6 is formed by the gap between the inner container 3 and the shell 2, and the top pipeline of the steam chamber 6 communicates with the external equipment. After injecting part of water into the steam chamber 6, the heat in the fire chamber is transmitted to the steam chamber 6 through the inner container 3, and the water in the steam chamber 6 is heated to form steam. In this embodiment, the external equipment includes a steamer 15 and a steaming plate 16, and the formed steam enters the steamer 15 and the steaming plate 16 through the pipeline, so that other foods can be heated by using steam.

[0031] In this embodiment, the outer side of the shell 2 is fixed with a water level observation transparent tube 9 in the vertical direction, and the upper and lower ends of the water level observation transparent tube 9 communicate with the steam chamber 6, so that the water level in the steam chamber 6 can be known through the water level observation transparent tube 9. The steam chamber 6 communicates with the external water storage bucket 14 through a pipeline and a water pump, so that when the water level in the steam chamber 6 is too low, water can be injected into the steam chamber 6 in time; at the same time, the injected water cannot exceed the high warning line of the water level observation transparent tube 9, so as to avoid injecting excessive water into the steam chamber 6 and affecting the space required by the steam.

[0032] It should be noted that the shell 2 is fixed with a drain pipe 13, the drain pipe 13 communicates with the inner bottom of the steam chamber 6, and a valve 7 is installed on the drain pipe 13, so that the water in the steam chamber 6 can be completely drained.

[0033] The inner container 3 is introduced as follows:

[0034] The inner liner 3 includes a support ring 301 fixed to the bottom of the outer shell 2. A pot-placement ring 302 is fixed to the upper end of the support ring 301. The pot-placement ring 302 is pot-shaped, wider at the top and narrower at the bottom, and its upper edge is fixed to the outer shell 2. This structure results in a larger volume of the steam chamber 6, allowing for the injection of more water; simultaneously, the larger heat conduction area enables rapid steam generation, leading to better performance.

[0035] The working principle is as follows:

[0036] The outer pot is placed inside the inner liner 3, with the upper edge of the outer pot outside the outer shell 2. Then, the burner 5 and the blower 12 work simultaneously to ignite the fuel. The flame generated by the combustion heats the outer pot in the combustion chamber, allowing the food inside the outer pot to be stir-fried or boiled. At the same time, the water in the steam chamber 6 is heated by heat conduction through the inner liner 3 to form steam. The generated steam is then transported through pipes to external equipment such as the steamer 15 and steaming tray 16, allowing other foods to be steamed or boiled.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0038] 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 these 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.
