[0002] In daily life, users often use health pots, rice cookers and other liquid heating devices to cook food, such as Tremella soup, mung bean paste, scented tea, soup, porridge, etc. Bubbles are generated in the cooking process, and the bubbles can stir the food when they move in the water. At the same time, the impact force generated when the bubbles burst can act on the surface of the food, making it easier to break and disperse the surface of the food, and precipitate more nutrients.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0047] The utility model provides a liquid heating device, which is intended to be able to blow air into the food to generate bubbles during the cooking process, and at the same time, blow air from the top of the cooking cavity to break the bubbles and prevent the bubbles from overflowing. It can be understood that the liquid heating device is not limited to a specific type of electrical appliance, such as a health pot, a rice cooker, or a soup pot. For ease of understanding, the following description takes the liquid heating device as a health pot as an example.

[0048] In the embodiment of the present utility model, Figures 1 to 4 As shown, the liquid heating device includes a kettle body 1, a heating component 2 and a gas generating device.

[0049] The kettle body 1 is provided with a cooking cavity 11a; the heating component 2 is provided on the kettle body 1 for heating the cooking cavity 11a; the gas generating device is provided on the kettle body 1, and the gas generating device has a first gas outlet end 32a and a second gas outlet end 32b, both of which are connected to the cooking cavity 11a, and the second gas outlet end 32b is higher than the first gas outlet end 32a.

[0050] In this embodiment, the heating component 2 is used to heat the cooking cavity 11a to cook the food in the cooking cavity 11a. The first gas outlet end 32a and the second gas outlet end 32b of the gas generating device can both blow gas into the cooking cavity 11a to generate bubbles in the food. When the bubbles rise, they stir the water and the food, and when the bubbles burst, they impact the food, so that the food is more quickly decomposed and nutrients are precipitated. There is no need to increase the heating power of the heating component 2, so that the heating component 2 can be prevented from being partially overheated and causing the food to burn.

[0051] It is understandable that the specific structure of the gas generating device can be determined according to the actual situation, such as a gas generating device, an air pump structure or a fan structure, etc., as long as it can blow air from the first gas outlet 32a and the second gas outlet 32b to the cooking cavity 11a. In actual application, the installation position of the gas generating device can be set at the bottom, side or top of the kettle body 1, and its specific installation position is not limited here.

[0052] The specific structure of the heating component 2 can also be determined according to actual conditions, such as a heating tube structure, an infrared heating plate structure or an electromagnetic heating structure, etc. The heating component 2 can heat the bottom of the cooking cavity 11a, or can also heat the surrounding wall of the cooking cavity 11a.

[0053] The specific positions of the first air outlet 32a and the second air outlet 32b can be determined according to actual conditions. For example, the first air outlet 32a and the second air outlet 32b are both connected to the lower area of ​​the cooking cavity 11a. At this time, blowing air into the food through the two air outlets can further accelerate the generation of bubbles and improve the cooking efficiency. Or, for example, one of the first air outlet 32a and the second air outlet 32b can be connected to the lower area of ​​the cooking cavity 11a to blow air into the food, and the other can be connected to the upper area of ​​the cooking cavity 11a to blow air toward the liquid surface of the food to eliminate bubbles and prevent the accumulation and overflow of bubbles. The specific positions of the first air outlet 32a and the second air outlet 32b are not limited here.

[0054] In the liquid heating device of the technical solution of the utility model, a gas generating device is arranged on the kettle body 1, and the gas generating device has a first gas outlet end 32a and a second gas outlet end 32b. The first gas outlet end 32a and the second gas outlet end 32b are both connected to the cooking cavity 11a. Therefore, in the process of cooking food, there is no need to additionally improve the heating efficiency. The first gas outlet end 32a and the second gas outlet end 32b are used to blow air into the food to increase bubbles, which can make the food evenly heated and accelerate the decomposition of the food to release nutrients.

[0055] In one embodiment of the present application, Figures 1 to 4 The first gas outlet end 32a is communicated with the lower portion of the cooking cavity 11a, and the second gas outlet end 32b is communicated with the upper portion of the cooking cavity 11a.

[0056] In this embodiment, the first air outlet end 32a is connected to the lower part of the cooking cavity 11a so that air can be blown into the food from the bottom of the cooking cavity 11a to generate bubbles. The bubbles stir the water and food when they rise, and impact the food when the bubbles burst, so that the food is broken down more quickly and nutrients are precipitated. In the middle and late stages of cooking food, the second air outlet end 32b is used to blow air from the upper part of the cooking cavity 11a to blow the air and liquid surface in the upper part of the cooking cavity 11a. Since the temperature of the gas is lower than the temperature of the bubbles, the bubbles accumulated above the liquid surface can be promoted to burst, thereby preventing the bubbles from overflowing from the outside of the pot body 1.

[0057] The first air outlet end 32a is connected to the lower part of the cooking cavity 11a. It can be understood that the first air outlet end 32a is located in the middle of the bottom wall or the side of the bottom wall of the cooking cavity 11a, or the first air outlet end 32a can also be located on the side wall of the cooking cavity 11a near the bottom, etc. As long as it can blow air from the bottom into the food, its specific position is not limited here.

[0058] The second gas outlet 32b is connected to the top of the cooking cavity 11a. It can be understood that the second gas outlet 32b is located at a position near the top of the side wall of the cooking cavity 11a, or the second gas outlet 32b can be located at the top opening of the cooking cavity 11a. For example, the second gas outlet 32b is set on the pot cover assembly 6 that covers the cooking cavity 11a, or it can be extended to the top opening of the cooking cavity 11a through a pipeline, etc. As long as the area near the top of the cooking cavity 11a can be blown to prevent the accumulation and overflow of bubbles, the specific position is not limited here.

[0059] In one embodiment of the present application, the gas generating device includes an air pump 31 and a gas delivery pipe, the air pump 31 is arranged on the kettle body 1; the gas delivery pipe is arranged inside the cooking cavity 11a or outside the cooking cavity 11a; the air inlet of the gas delivery pipe is connected to the air pump 31, and the gas delivery pipe has two air outlets, one air outlet is a first air outlet end 32a, and the other air outlet is a second air outlet end 32b.

[0060] This embodiment illustrates the structure of the gas generating device, and the gas pump 31 drives the airflow and pumps the gas into the cooking cavity 11a. The gas delivery pipe is used to blow the gas from the first gas outlet 32a and the second gas outlet 32b into the cooking cavity 11a.

[0061] With such an arrangement, there is no need to limit the specific installation position of the air pump 31, and the function of blowing air into the cooking cavity 11a can be achieved only through the routing of the gas delivery pipe.

[0062] In one embodiment of the present application, Figure 3 and Figure 5 The gas generating device includes an air pump 31 and a three-way pipe fitting 32. The air pump 31 is arranged on the kettle body 1; the three-way pipe fitting 32 includes an air inlet pipe 321, a first air outlet pipe 322 and a second air outlet pipe 323 which are connected to each other. The air inlet end of the air inlet pipe 321 is connected to the air pump 31, the air outlet end of the first air outlet pipe 322 is the first air outlet end 32a, and the air outlet end of the second air outlet pipe 323 is the second air outlet end 32b.

[0063] This embodiment illustrates the structure of the gas generating device, and the air pump 31 drives the air flow and pumps the gas into the cooking cavity 11a. The three-way pipe 32 connects the air pump 31 with the cooking cavity 11a, so that the air can smoothly enter the cooking cavity 11a. In this way, the specific installation position of the air pump 31 is not limited, and the function of blowing air into the cooking cavity 11a can be realized only through the pipe of the three-way pipe 32.

[0064] In addition, by adopting a three-way pipe fitting 32, its air inlet pipe 321 is connected to the air outlet of the air pump 31, and the first air outlet pipe 322 and the second air outlet pipe 323 are respectively connected to the bottom and the top of the cooking cavity 11a. Compared with the method of separately setting pipes for the two air paths, the present embodiment only needs one air pump 31 to achieve two different air outlets, and there is no need to specially set up different air pumps 31 to achieve this, which simplifies the internal structure of the kettle body 1, simplifies assembly, and reduces costs.

[0065] In one embodiment of the present application, Figure 4 and Figure 6 The gas generating device also includes a solenoid valve assembly 33 arranged on the three-way pipe fitting 32, and the solenoid valve assembly 33 is located at the connection between the air inlet pipe 321, the first air outlet pipe 322 and the second air outlet pipe 323, and is used to control the connection and disconnection of the air inlet pipe 321 and the first air outlet pipe 322 and / or the second air outlet pipe 323.

[0066] In this embodiment, a solenoid valve assembly 33 is provided on the three-way pipe fitting 32. The solenoid valve assembly 33 can control the air inlet pipe 321 of the three-way pipe fitting 32 to be connected only to the first air outlet pipe 322, or the air inlet pipe 321 to be connected only to the second air outlet pipe 323, or the air inlet pipe 321 to be connected to both the first air outlet pipe 322 and the second air outlet pipe 323. The air outlet volume, air outlet time, air outlet frequency, etc. of the first air outlet end 32a and the second air outlet end 32b can be adjusted according to the cooking process of different ingredients to achieve a better cooking effect.

[0067] As an example, take cooking mung bean or rice porridge as an example: in the early stage of cooking, when the water has not yet boiled, only the heating power can be increased to accelerate the boiling of water, and the air pump 31 is not turned on. At this time, neither the first air outlet 32a nor the second air outlet 32b emits air. When entering the middle stage of cooking after boiling, the heating power can be reduced and the air pump 31 can be turned on. Since fewer bubbles are generated at this stage, no bubbles will accumulate above the liquid surface. At this time, the solenoid valve assembly 33 can only connect the air inlet pipe 321 and the first air outlet pipe 322, and the air inlet pipe 321 and the second air outlet pipe 323 can be cut off, so that only the first air outlet 32a emits air, and the second air outlet 32b does not blow air, thereby increasing the number of bubbles in the food and accelerating the breaking of the mung bean and rice shells and the precipitation of nutrients. In the middle and late stages of cooking after boiling for a period of time, bubbles begin to accumulate above the liquid surface. At this time, the air inlet pipe 321 and the second air outlet pipe 323 can be connected through the electromagnetic valve assembly 33, so that the second air outlet end 32b blows air from the top of the cooking chamber 11a to eliminate bubbles. In this stage, the first air outlet end 32a and the second air outlet end 32b can blow air at the same time, or the first air outlet end 32a and the second air outlet end 32b can alternately blow air to prevent the accumulation of bubbles on the top from overflowing. In the final stage when cooking is almost complete, the electromagnetic valve assembly 33 can only connect the air inlet pipe 321 and the second air outlet pipe 323, and cut off the air inlet pipe 321 and the first air outlet pipe 322, so that the first air outlet end 32a does not blow air, and only the second air outlet end 32b blows air, so as to prevent bubbles in the thick soup that are not broken in time from overflowing from the pot.

[0068] It is understandable that in actual application, the timing of opening the air pump 31, the air outlet state of the first air outlet end 32a and the second air outlet end 32b, the air outlet time and the air outlet frequency are not limited to the above embodiments. The opening and control of the specific air pump 31 and the electromagnetic valve assembly 33 can be determined according to the actual cooking ingredients or user preferences. For example, when the cooked ingredients are ingredients containing saponin substances that easily generate bubbles (such as ginseng slices), only the second air outlet end 32b can be opened to blow air to prevent bubbles from accumulating and overflowing, and the first air outlet end 32a can be reduced or not opened to blow air. Or, for example, when the cooked ingredients are relatively refreshing scented teas, there are few bubbles accumulated on the top. At this time, only the first air outlet end 32a can be opened to blow air to accelerate the churning of the liquid without opening the second air outlet end 32b.

[0069] In some other embodiments, solenoid valves may be respectively provided on the first air outlet pipe 322 and the second air outlet pipe 323 , and the two solenoid valves are respectively controlled to realize different blowing modes.

[0070] In one embodiment of the present application, the liquid heating device further includes a temperature sensing component 4 disposed in the cooking cavity 11a. It can be understood that the temperature sensing component 4 is electrically connected to the electric control component 5 of the liquid heating device, and the electric control component 5 is electrically connected to the air pump 31 and the electromagnetic valve component 33. The temperature sensing component 4 is used to detect the temperature of the food in the cooking cavity 11a, and then it can be determined whether the food liquid is boiling. For example, when the detected temperature is lower than 100°C, the food liquid has not yet boiled, and the air pump 31 can be turned off at this time; when the detected temperature reaches 100°C, the food liquid is boiling, and the air pump 31 can be turned on at this time to control the electromagnetic valve 33 component to operate so that the first air outlet 32a blows air.

[0071] In one embodiment of the present application, the liquid heating device further comprises an anti-overflow probe (not shown) located at the top of the cooking cavity 11a. The anti-overflow probe is electrically connected to the electric control component 5 of the liquid heating device. The anti-overflow probe is used to detect whether there are bubbles in the upper part of the cooking cavity 11a. If bubbles are detected, the electric control component 5 can control the solenoid valve component 33 to operate so that the second air outlet 32b blows air to eliminate bubbles and prevent the bubbles from overflowing; if no bubbles are detected, the second air outlet 32b may not be opened for blowing. Optionally, the anti-overflow probe can be set at a position near the top of the side wall of the kettle body 1, or can be set on the kettle cover component 6.

[0072] In order to generate more small bubbles in the food liquid, in one embodiment of the present application, Figures 2 to 4 The liquid heating device further includes a foaming component 34 disposed in the cooking cavity 11a, and the foaming component 34 is installed at the first air outlet end 32a.

[0073] By setting a foaming component 34 at the first gas outlet end 32a, this embodiment can disperse the gas flowing out of the first gas outlet end 32a to form more tiny bubbles, thereby accelerating the growth, rupture and flow of the bubbles, making it easier for food molecules to rupture and disperse, shortening the cooking time and precipitating more nutrients.

[0074] In actual application, the foaming component 34 can cover the bottom wall of the cooking cavity 11a to increase the area for gas outlet, thereby increasing the area for generating bubbles and achieving a better cooking effect.

[0075] Furthermore, the first gas outlet end 32a extends into the bottom of the cooking cavity 11a, and the foaming component 34 is detachably connected to the first gas outlet end 32a.

[0076] It is understandable that extending the first air outlet end 32a into the bottom of the cooking cavity 11a can facilitate the installation of the first air outlet pipe 322 and the cooking cavity 11a. The foaming component 34 is detachably connected to the first air outlet end 32a, which is convenient for users to disassemble and clean the foaming component 34 and the inside of the cooking cavity 11a.

[0077] Optionally, the foaming component 34 can be detachable with the first air outlet pipe 322 through a threaded connection, a snap connection, or a magnetic connection.

[0078] In practical applications, the foaming component 34 can be a filter structure, a grid structure, or a porous ceramic structure.

[0079] In one embodiment of the present application, Figures 3 to 6 A one-way valve 35 is provided on the first air outlet pipe 322 for one-way conduction from the air pump 31 to the first air outlet end 32a.

[0080] It can be understood that the first air outlet end 32a is connected to the bottom of the cooking cavity 11a, and food may enter the first air outlet pipe 322. In this embodiment, a one-way valve 35 is set on the first air outlet pipe 322 to allow gas to flow in one direction, thereby preventing the liquid in the cavity from flowing back into the air pump 31 and causing malfunction or damage.

[0081] In one embodiment of the present application, a one-way valve (not shown) is disposed on the second air outlet pipe 322 for one-way conduction from the air pump 31 to the second air outlet end 32 a.

[0082] This arrangement can prevent the liquid in the cavity from flowing back into the air pump 31 through the second air outlet pipe 322 and causing malfunction or damage.

[0083] In one embodiment of the present application, a filter assembly 36 is provided at the air inlet of the air pump 31 .

[0084] Such an arrangement can prevent impurities and dust in the air from entering the air pump 31 and causing malfunction or damage.

[0085] In one embodiment of the present application, Figures 2 to 4 The kettle body 1 includes an inner pot 11 and a shell 12, and the inner pot 11 forms a cooking cavity 11a; the shell 12 is arranged outside the inner pot 11, and the heating component 2 and the air pump 31 are located in the shell 12; the first air outlet pipe 322 passes through the bottom wall of the inner pot 11, and the second air outlet pipe 323 extends from the outside of the inner pot 11 to the top of the inner pot 11 to connect with the cooking cavity 11a.

[0086] This embodiment illustrates the structure of the kettle body 1. The kettle body 1 includes a shell 12 and an inner liner 11 disposed in the shell 12. It can be understood that the inner liner 11 serves to cook food, and the shell 12 serves to wrap and install internal components and ensure the integrity of the appearance. The first air outlet pipe 322 is provided through the bottom wall of the inner liner 11. Optionally, the first air outlet pipe 322 is sealed and connected to the bottom wall of the inner liner 11. The second air outlet pipe 323 extends from the outside of the inner liner 11 to the top of the inner liner 11. Optionally, the second air outlet pipe 323 is spaced apart from the inner liner 11 to prevent the second air outlet pipe 323 from being deformed due to heat caused by excessive temperature of the inner liner 11.

[0087] As an example, the inner liner 11 and the shell 12 are detachably mounted, so that the inner liner 11 can be easily cleaned.

[0088] In one embodiment, the shell 12 includes an outer shell 121 and a bottom shell 122, the outer shell 121 is arranged on the outer periphery of the inner tank 11; the bottom shell 122 is arranged below the outer shell 121, the heating component 2 is arranged on the bottom shell 122 and connected to the outer surface of the bottom wall of the inner tank 11, the air pump 31 is arranged on the bottom shell 122, and the second air outlet pipe 323 extends from the bottom of the inner tank 11 from the outside of the inner tank 11 to the top of the inner tank 11.

[0089] The housing 12 includes an outer shell 121 and a bottom shell 122. The outer shell 121 can be an integral structure or a split structure with the bottom shell 122. As an example, the outer shell 121 can be detachably connected to the bottom shell 122, which can facilitate the inspection and maintenance of components such as the air pump 31, the heating component 2, and the electronic control component 5 installed in the bottom shell 122.

[0090] In this embodiment, the air pump 31 is installed on the bottom shell 122. By extending the first air outlet pipe 322 upward from the air inlet pipe 321 to the bottom wall of the inner pot 11, and the second air outlet pipe 323 extends from the bottom of the inner pot 11 from the outside of the inner pot 11 to the top of the inner pot 11, the function of blowing air smoothly into the cooking cavity 11a of the inner pot 11 is achieved.

[0091] As an example, the connection between the air inlet pipe 321 , the first air outlet pipe 322 and the second air outlet pipe 323 can be arranged on the bottom shell 122 , and accordingly, the solenoid valve assembly 33 can be arranged on the bottom shell 122 , so that the three-way pipe fitting 32 can be easily maintained.

[0092] In one embodiment, if Figures 2 to 6 The kettle body 1 further includes a handle 13 disposed on the outer wall of the shell 121, and the handle 13 is a hollow structure.
