Description

Technical Field

[0001] This invention relates to the field of cooking utensil technology, and more specifically to a cooking utensil. Background Technology

[0002] In related technologies, the steam generators of cooking appliances such as steam ovens typically use heating elements to heat the water tank, causing the water in the tank to boil and evaporate, thereby generating steam to heat the food. However, the steam generated in this way is relatively slow, which affects the cooking effect on the food. Summary of the Invention

[0003] The present invention aims to at least address one of the technical problems existing in the prior art, namely, the slow steam generation speed of cooking appliances such as steam ovens.

[0004] Therefore, one aspect of the present invention provides a cooking utensil.

[0005] In view of the above, according to one aspect of the present invention, a cooking appliance is provided, comprising: a cooking inner pot, the cooking inner pot including a cooking cavity; a flash evaporator assembly disposed outside the cooking cavity; a first gas supply assembly communicating with the cooking cavity and the flash evaporator assembly, the first gas outlet of the first gas supply assembly being located at the lower part of the cooking cavity; and a second gas supply assembly communicating with the cooking cavity and the flash evaporator assembly, the second gas outlet of the second gas supply assembly being located at the upper part of the cooking cavity.

[0006] The cooking appliance proposed in this invention includes a cooking inner pot, a flash steamer assembly, a first gas supply assembly, and a second gas supply assembly. The cooking inner pot includes a cooking cavity for placing materials for cooking. The flash steamer assembly is located outside the cooking cavity and is connected to the cooking cavity through the first and second gas supply assemblies. The flash steamer assembly can introduce a large amount of steam into the cooking cavity in a short time through the first and / or second gas supply assemblies, thereby achieving rapid cooking and reducing the impact of prolonged heating on the taste or appearance of food.

[0007] Furthermore, with the first gas supply component located at the lower part of the cooking chamber and the second gas supply component located at the upper part of the cooking chamber, steam can enter the cooking chamber simultaneously through both the upper and lower parts, allowing the cooking chamber to quickly fill with steam. Moreover, during food cooking, the temperature difference between the upper and lower parts of the food is reduced, and their temperatures are closer, thereby improving the cooking effect.

[0008] In addition, the cooking utensil according to the above-described technical solution provided by the present invention may also have the following additional technical features:

[0009] Based on the above technical solution, the flash evaporator assembly further includes: a container; a heating element for heating the container; and a switching valve, which includes an inlet end and an outlet end, the inlet end being connected to the container and the outlet end being connected to the first gas delivery assembly.

[0010] In this technical solution, the flash evaporator assembly includes a container, a heating element, and a switching valve. The inlet end of the switching valve is connected to the container, and the outlet end of the switching valve is connected to the first gas delivery assembly. The heating element can heat the container, and by adding liquid into the container, the heating element heats the container, causing the liquid in the container to evaporate, increasing the temperature and pressure inside the container. The switching valve can then open when the pressure and / or temperature inside the container meet preset conditions, allowing the high-temperature, high-pressure liquid to be discharged from the container. The pressure drops rapidly, the boiling point of the liquid decreases, and it vaporizes rapidly, forming a large amount of steam, which is then delivered to the cooking chamber through the first gas delivery assembly, thereby improving the cooking effect.

[0011] Based on any of the above technical solutions, the flash evaporator assembly further includes: a detection component disposed in the container for detecting at least one of the pressure and temperature inside the container.

[0012] In this technical solution, the flash evaporator assembly also includes a detection component, which is installed on the container. The detection component is used to detect at least one of the pressure and temperature inside the container. Then, by adding liquid into the container, the heating element heats the container, causing the liquid inside the container to evaporate, increasing the temperature and pressure inside the container. When the detection component detects that the pressure and / or temperature inside the container meet preset conditions, the switching valve is opened, so that the high-temperature and high-pressure liquid is discharged from the container, the pressure is rapidly reduced, the boiling point of the liquid decreases, and it is rapidly vaporized to form a large amount of steam, which is delivered to the cooking chamber through the first gas delivery component, thereby improving the cooking effect.

[0013] Based on any of the above technical solutions, the flash evaporator assembly further includes: a one-way valve connected to the input end of the container, allowing one-way flow from the outside of the container to the inside of the container.

[0014] In this technical solution, the flash evaporator assembly also includes a one-way valve, which is located at the inlet end of the container. The one-way valve is unidirectionally open from the outside of the container to the inside of the container, so that when the heating element heats the liquid in the container, the liquid in the container will not flow back to the outside through the inlet end of the container due to the increase in pressure.

[0017] The system includes a one-way valve positioned between the infusion assembly and the container, with unidirectional flow from the infusion assembly to the container. This one-way valve prevents backflow of liquid from the container to the infusion assembly when the heating assembly heats the liquid inside the container due to increased pressure.

[0018] Based on any of the above technical solutions, the flash evaporator assembly further includes: a filter element disposed in the container for filtering between the container and the switching valve.

[0019] In this technical solution, a filter element is also provided inside the container or between the container and the switching valve, which is used for filtering at the output end of the container, thereby reducing the possibility of impurities in the liquid inside the container entering the first gas delivery assembly.

[0020] Based on any of the above technical solutions, the flash evaporator assembly further includes: a pressure relief valve located in the container.

[0021] In this technical solution, the flash evaporator assembly also includes a pressure relief valve installed on the container, which can reduce the pressure in the container after the pressure inside the container reaches the upper limit pressure, thereby reducing the risk of the container exploding due to excessive internal pressure.

[0022] Based on any of the above technical solutions, the flash evaporator assembly further includes: an insulation element disposed on the outside of the container.

[0023] In this technical solution, the flash evaporator assembly also includes an insulation component disposed outside the container. The insulation component covers the outer wall of the container, thereby reducing the heat consumption of the container, improving the energy efficiency of the heating component, and reducing the degree of heat diffusion of the container, thus reducing the possibility of other components being damaged due to excessive temperature.

[0024] Based on any of the above technical solutions, the flash evaporator assembly further includes: a temperature controller, located in the container and electrically connected to the heating element.

[0025] In this technical solution, the flash evaporator assembly also includes a temperature controller, which is installed on the container and electrically connected to the heating element, thereby providing a safety function for the heating element. When the temperature of the container is too high, the heating element can respond to the feedback of the temperature controller and stop heating, thus improving the safety of the flash evaporator assembly.

[0026] Based on any of the above technical solutions, the second gas supply assembly further includes: a gas supply pipe, one end of which is connected to the flash evaporator assembly; and a steam injection assembly, located in the cooking chamber and connected to the other end of the gas supply pipe. The steam injection assembly is located inside the cooking chamber, and a second gas outlet is provided at the end of the steam injection assembly facing away from the gas supply pipe.

[0027] In this technical solution, the second gas supply component includes a gas supply pipe and a steam injection component. The gas supply pipe connects the flash evaporator component and the steam injection component. The steam injection component is installed on the cooking chamber. Furthermore, the second gas outlet is located at the end of the steam injection component away from the gas supply pipe, which can increase the steam jet speed in the cooking chamber, thereby achieving a specific cooking effect.

[0028] Based on any of the above technical solutions, the steam injection assembly further includes: a base disposed in the cooking chamber; a steam injection element disposed in the base, the steam injection element being connected to the second gas delivery assembly.

[0029] In this technical solution, the steam injection assembly includes a base and a steam injection component. The base is mounted on the cooking pot, and the steam injection component is mounted on the base, thereby improving the stability of the steam injection assembly.

[0030] Based on any of the above technical solutions, it further includes: a first valve body, disposed on the first gas delivery assembly, used to control the opening and closing of the first gas delivery assembly.

[0031] In this technical solution, the cooking appliance also includes a first valve body, which is disposed in the first gas supply component to control the opening and closing of the first gas supply component. In turn, it cooperates with the second gas supply component to control the total amount of steam output in the cooking chamber, thereby achieving different cooking effects.

Detailed Implementation

[0045] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0047] The following reference Figures 1 to 3 To describe a cooking appliance 100 provided according to some embodiments of the present invention.

[0048] Example 1:

[0049] like Figure 1 As shown, the present invention provides a cooking appliance 100, which includes a cooking inner pot 110, a flash evaporator assembly 120, a first gas supply assembly 140, and a second gas supply assembly 150. The cooking inner pot 110 includes a cooking cavity for holding food ingredients 200. The flash evaporator assembly 120 is disposed outside the cooking cavity. Specifically, the flash evaporator assembly 120 can be disposed on the cooking inner pot 110, or it can be disposed on the housing of the cooking appliance 100, with the housing disposed outside the cooking inner pot 110. One end of the first gas supply assembly 140 is connected to the flash evaporator assembly, and the other end is connected to the cooking inner pot 110, thereby connecting the interior of the flash evaporator assembly 120 and the cooking cavity. One end of the second gas supply assembly 150 is connected to the flash evaporator assembly 120, and the other end is connected to the cooking inner pot 110, thereby connecting the interior of the flash evaporator assembly 120 and the cooking cavity. The liquid involved in this invention can be water or a solution of water.

[0050] The cooking appliance 100 provided by the present invention includes a cooking inner pot 110, a flash steamer assembly 120, a first gas supply assembly 140, and a second gas supply assembly 150. The cooking inner pot 110 includes a cooking cavity for placing materials for cooking. The flash steamer assembly 120 is disposed outside the cooking cavity and is connected to the cooking cavity through the first gas supply assembly 140 and the second gas supply assembly 150. The flash steamer assembly 120 can introduce a large amount of steam into the cooking cavity in a short time through the first gas supply assembly 140 and / or the second gas supply assembly 150, thereby achieving the effect of rapid cooking and reducing the impact of prolonged heating on the taste or appearance of food.

[0051] Specifically, cooking appliances 100 include steamers, steam ovens, or microwave steamers, etc.

[0052] In this design, the first gas supply component 140 is located at the lower part of the cooking chamber, and the second gas supply component 150 is located at the upper part of the cooking chamber. This allows steam to enter the cooking chamber simultaneously through both the upper and lower parts, enabling the cooking chamber to quickly fill with steam. Furthermore, during food cooking, this reduces the temperature difference between the upper and lower parts of the food, bringing their temperatures closer together and improving the cooking effect.

[0053] Specifically, the middle position inside the cooking cavity is used as the dividing line, with the area below the middle position being the lower part and the area above the middle position being the upper part. The first air outlet of the first air supply assembly 140 is located in the lower part of the cooking cavity, and the second air outlet of the second air supply assembly 150 is located in the upper part of the cooking cavity.

[0054] Alternatively, the cooking appliance 100 typically has a shelf that is horizontally supported in the cooking cavity. The shelf is located at a certain distance from both the top and bottom walls of the cooking pot 110. Therefore, the area above the shelf is the upper part of the cooking cavity, and the area below the shelf is the lower part of the cooking cavity.

[0055] Example 2:

[0056] like Figure 2 and Figure 3 As shown, based on Embodiment 1, the flash evaporator assembly 120 further includes a container 122, a heating element 124, and a switching valve 126. The container 122 is used to hold liquid, the output end of the container 122 is connected to the inlet end of the switching valve 126, and the outlet end of the switching valve 126 is connected to the first gas delivery assembly 140.

[0057] In this embodiment, the flash evaporator assembly 120 includes a container 122, a heating element 124, and a switching valve 126. The inlet end of the switching valve 126 is connected to the container 122, and the outlet end of the switching valve 126 is connected to the first gas delivery assembly 140. The heating element 124 can heat the container 122. By adding liquid into the container 122, the heating element 124 heats the container 122, causing the liquid in the container 122 to evaporate, increasing the temperature and pressure inside the container 122. The switching valve 126 can then open when the pressure and / or temperature inside the container 122 meet preset conditions. This allows the high-temperature, high-pressure liquid to be discharged from the container 122, rapidly depressurize, and lower the boiling point of the liquid, thus rapidly vaporizing to form a large amount of steam. This steam is then delivered to the cooking chamber through the first gas delivery assembly 140, thereby improving the cooking effect.

[0058] Specifically, the heating element 124 includes a heating tube or heating plate, etc. The switching valve 126 is a solenoid valve.

[0059] Specifically, the heating element 124 can be embedded in the container 122, or disposed on the outer wall of the container 122, or inserted into the container 122.

[0060] Example 3:

[0061] like Figure 2 As shown, based on Embodiment 2, the flash evaporator assembly 120 further includes a detection assembly 128, which is disposed on the container 122 and is capable of detecting at least one of the pressure and temperature inside the container 122.

[0062] In this embodiment, the flash evaporator assembly 120 further includes a detection assembly 128, which is disposed on the container 122. The detection assembly 128 is used to detect at least one of the pressure and temperature inside the container 122. Then, by adding liquid into the container 122, the heating element 124 heats the container 122, thereby causing the liquid inside the container 122 to evaporate, increasing the temperature and pressure inside the container 122. When the detection assembly 128 detects that the pressure and / or temperature inside the container 122 meets preset conditions, the switching valve 126 is opened, so that the high-temperature and high-pressure liquid is discharged from the container 122, and the pressure is rapidly reduced, the boiling point of the liquid is lowered, and thus it is rapidly vaporized to form a large amount of steam, which is delivered to the cooking chamber through the first gas delivery assembly 140, thereby improving the cooking effect.

[0063] Specifically, the liquid inside the container 122 can be heated by the heating element 124, thereby increasing the pressure and temperature inside the container 122. The detection component 128 detects the pressure inside the container 122. When the pressure inside the container 122 reaches a preset pressure value, the heating element 124 can stop heating to improve the safety of the container 122, or continue heating to maintain the pressure and temperature of the liquid inside the container 122 at a high range. Then, when steam is needed, the switch valve 126 is opened, and the high-temperature and high-pressure liquid inside the container 122 is quickly discharged through the liquid outlet, thereby rapidly reducing the liquid pressure. As the pressure decreases, the boiling point of the liquid also decreases, allowing the liquid to evaporate into steam quickly and over a large area, thus achieving rapid and large-scale steam generation, thereby increasing the steam ejection pressure and improving the cooking effect.

[0064] Specifically, the liquid inside the heating container 122 can be heated by adding a component, thereby increasing the pressure and temperature inside the container 122. The detection component 128 detects the temperature inside the container 122. When the temperature inside the container 122 reaches the preset temperature value, the heating element 124 can stop heating to improve the safety of the container 122, or continue heating to maintain the pressure and temperature of the liquid inside the container 122 within a high range. Then, when steam is needed, the switch valve 126 is opened, and the high-temperature and high-pressure liquid inside the container 122 is quickly discharged through the liquid outlet, thereby rapidly reducing the liquid pressure. As the pressure decreases, the boiling point of the liquid also decreases, allowing the liquid to evaporate into steam quickly and over a large area, thus achieving rapid and large-scale steam generation, thereby increasing the steam ejection pressure and improving the cooking effect.

[0065] Specifically, the heating element 124 heats the liquid inside the container 122, thereby increasing the pressure and temperature inside the container 122. The detection component 128 detects the pressure and temperature inside the container 122. When the pressure inside the container 122 reaches a preset pressure value, the heating element 124 can stop heating to improve the safety of the container 122, or it can continue heating to maintain the pressure and temperature of the liquid inside the container 122 within a high range. Then, when steam is needed, the switch valve 126 is opened, and the high-temperature, high-pressure liquid inside the container 122 is quickly discharged through the liquid outlet, thereby rapidly reducing the liquid pressure. As the pressure decreases, the boiling point of the liquid also decreases, allowing the liquid to evaporate into steam quickly and over a large area, thus achieving rapid and large-scale steam generation. This increases the steam ejection pressure and improves the cooking effect.

[0066] Example 4:

[0067] like Figure 3 As shown, based on Embodiment 2 or Embodiment 3, the flash evaporator assembly 120 further includes a one-way valve 130, which is connected to the input end of the container 122 and is unidirectionally open from the outside of the container 122 to the inside of the container 122.

[0068] In this embodiment, the flash evaporator assembly 120 further includes a one-way valve 130, which is disposed at the input end of the container 122. The one-way valve 130 is unidirectionally open from the outside of the container 122 to the inside of the container 122, so that when the heating element 124 heats the liquid in the container 122, the liquid in the container 122 will not flow back to the outside through the input end of the container 122 due to the increase in pressure.

[0069] Example 5:

[0070] like Figures 1 to 3 As shown, based on any of Embodiments 2 to 4, the flash evaporator assembly 120 further includes a liquid delivery assembly 132, which is connected to a one-way valve 130 and is used to deliver liquid into the container 122.

[0071] In this embodiment, the flash evaporator assembly 120 also includes a liquid delivery assembly 132 connected to the one-way valve 130, thereby actively delivering liquid into the container 122 through the liquid delivery assembly 132 to increase the liquid inlet speed of the container 122.

[0072] A one-way valve 130 is disposed between the infusion assembly 132 and the container 122, and the one-way valve 130 is unidirectionally open from the infusion assembly 132 to the container 122. By providing a one-way valve 130 between the infusion assembly 132 and the container 122, and ensuring unidirectional openness from the infusion assembly 132 to the container 122, the liquid in the container 122 will not flow back to the infusion assembly 132 due to increased pressure when the heating element 124 heats the liquid in the container 122.

[0073] Specifically, the infusion assembly 132 is a pump body, which can pump liquid into the container 122 by means of pumping.

[0074] Example 6:

[0075] like Figure 3 As shown, based on any of Embodiments 2 to 5, the flash evaporator assembly 120 further includes a filter element 136, which is disposed inside the container 122 or between the container 122 and the switching valve 126. The filter element 136 is used for filtration between the container 122 and the switching valve 126.

[0076] In this embodiment, a filter element 136 is also provided inside the container 122 or between the container 122 and the switching valve 126, which is used for filtering at the output end of the container 122, thereby reducing the possibility of impurities in the liquid inside the container 122 entering the first gas delivery assembly 140.

[0077] Specifically, if minerals such as calcium carbonate, magnesium hydroxide, magnesium carbonate, or calcium sulfate are present in the liquid, the minerals in the liquid may form scale when the liquid is heated. If the scale enters the next component of the cooking appliance 100, it will eventually be sprayed into the cooking cavity of the cooking appliance 100, affecting the cooking effect of the food or causing blockage of components such as pipes and valves 126.

[0078] The filter element 136 can filter out scale in the liquid, reduce the possibility of blockage in components such as pipes and valves 126, and improve the cooking effect of the cooking appliance 100.

[0079] Specifically, the filter element 136 can be placed horizontally inside the container 122, so that when the liquid passes through the filter element 136 and is discharged from the outlet of the container 122, the filter element 136 will filter out the scale in the liquid, so that the liquid or steam discharged from the container 122 is clean and tidy.

[0080] Alternatively, the filter element 136 can be installed at the outlet of the container 122, so that when the liquid is discharged through the filter element 136 to the outlet, the filter element 136 will filter out the scale in the liquid, so that the liquid or steam discharged from the container 122 is clean and tidy.

[0081] Alternatively, the filter element 136 can be disposed between the container 122 and the switch valve 126, so that when the liquid is discharged through the filter element 136 to the switch valve 126, the filter element 136 will filter out the scale in the liquid, making the liquid or steam discharged from the container 122 clean and tidy.

[0082] The filter element 136 includes a filter screen.

[0083] Specifically, container 122 can be a split structure, including a body, a cover, a seal, screws, nuts, etc. The seal is located between the body and the cover, and the body and the cover are fastened together and fixed by screws and nuts.

[0084] The filter element 136 is disposed at the opening of the main body and on the edge of the main body. The filter element 136 is provided with a through hole so that liquid can smoothly enter the main body. The filter element 136 also includes a protrusion that extends into the liquid outlet of the container 122.

[0087] In this embodiment, the flash evaporator assembly 120 also includes a pressure relief valve 134 disposed on the container 122, which can reduce the pressure in the container 122 after the pressure inside the container 122 reaches the upper limit pressure, thereby reducing the risk of the container 122 exploding due to excessive internal pressure.

[0089] Based on any of Embodiments 2 to 7, the flash evaporator assembly 120 further includes an insulation element that covers the outer wall of the container 122.

[0090] In this embodiment, the flash evaporator assembly 120 also includes an insulation element disposed outside the container 122. The insulation element covers the outer wall of the container 122, thereby reducing the heat consumption of the container 122, improving the energy efficiency of the heating element 124, and reducing the degree of heat diffusion of the container 122, thus reducing the possibility of other components being damaged due to excessive temperature.

[0091] Specifically, the insulation component is an insulation film or insulation sleeve, etc.

[0092] Example 9:

[0093] like Figure 3As shown, based on any of Embodiments 2 to 8, the flash evaporator assembly 120 further includes a temperature controller 138 disposed on the container 122, and the temperature controller 138 is electrically connected to the heating element 124.

[0094] In this embodiment, the flash evaporator assembly 120 further includes a temperature controller 138, which is disposed on the container 122 and electrically connected to the heating element 124. This temperature controller 138 acts as a safety device for the heating element 124; when the temperature of the container 122 becomes too high, the heating element 124 can respond to the feedback from the temperature controller 138 and stop heating, thus improving the safety of the flash evaporator assembly 120. The temperature controller 138 can be directly connected to a controller or directly connected to the heating element 124 to control the heating element 124 to shut down via the controller or directly control the heating element 124 to shut down.

[0095] Specifically, the thermostat 138 abuts against the outer wall of the container 122.

[0096] Example 10:

[0097] like Figure 1 As shown, based on any one of Embodiments 1 to 9, the second gas supply assembly 150 further includes a gas supply pipe 152 and a steam injection assembly 154. One end of the gas supply pipe 152 is connected to the flash evaporator assembly 120, and the other end of the gas supply pipe 152 is connected to the steam injection assembly 154. The steam injection assembly 154 is disposed on the cooking chamber 110, and at least a portion of the steam injection assembly 154 is disposed inside the cooking chamber.

[0098] In this embodiment, the second gas delivery assembly includes a gas delivery pipe 152 and a steam injection assembly. The gas delivery pipe 152 connects the flash evaporator assembly and the steam injection assembly. The steam injection assembly is installed on the cooking chamber, and the second gas outlet is located at the end of the steam injection assembly away from the gas delivery pipe 152, which can increase the steam jet speed in the cooking chamber, thereby achieving a specific cooking effect.

[0099] Specifically, the switching valve 126 is connected to a connector 190, on which a second gas delivery assembly 150 and a first gas delivery assembly 140 are arranged side by side.

The steam injection element 158 ​​is disposed on the base 156, which is disposed on the cooking chamber 110 and at least partially located inside the cooking cavity. The steam injection element 158 ​​is connected to the second gas delivery assembly 150, so that the steam generated by the flash evaporator assembly 120 can be discharged into the cooking cavity through the steam injection element 158. The steam injection element 158 ​​is movably disposed on the base 156.

[0102] In this embodiment, the steam injection assembly 154 includes a base 156 and a steam injection element 158. The base 156 is disposed on the cooking chamber 110, and the steam injection element 158 ​​is movably disposed on the base 156. The steam injection element 158 ​​is connected to the second gas delivery assembly 150, allowing it to move within the cooking chamber and thus change the steam outlet position of the steam injection assembly 154. This allows for targeted steam output to specific locations for different materials, achieving specific cooking effects. Furthermore, the movable steam element enables localized cooking of the food 200. For example, if a portion of the food 200 is thicker, or if different parts of the food 200 require different levels of doneness, the steam injection element 158 ​​can be moved to the appropriate location to improve the localized doneness of the food 200.

[0103] Specifically, the steam injection component 158 ​​includes a steam injection pipe and a nozzle.

[0104] Specifically, a guide groove is provided on the base 156, and the steam injection component 158 ​​is rotatably mounted on the base 156. The steam injection component 158 ​​can rotate along the guide groove.

[0105] Furthermore, the steam injection assembly 154 also includes a drive unit, which includes a motor. The drive unit is mounted on the base 156, and its output end is connected to the steam injection component 158. Thus, the drive unit can drive the steam injection component 158 ​​to rotate along the guide groove.

[0106] Specifically, the steam outlet of the steam injector 158 can be adjusted in the height direction within the cooking pot 110.

[0107] Example 12:

[0108] like Figure 1 As shown, based on Embodiments 1 to 11, the cooking appliance 100 further includes a first valve body 170, which is disposed on the first gas supply assembly 140. When the first valve body 170 is closed, the first gas supply assembly 140 is in a cut-off state, and when the first valve body 170 is open, the first gas supply assembly 140 is in a conducting state.

[0109] In this embodiment, the cooking appliance 100 also includes a first valve body 170, which is disposed in the first gas supply assembly 140 to control the opening and closing of the first gas supply assembly 140. In turn, it cooperates with the second gas supply assembly 150 to control the total amount of steam output in the cooking chamber, thereby achieving different cooking effects.

[0110] Specifically, there are one or more first gas supply components 140, and each first gas supply component 140 corresponds to a first valve body 170. The gas supply pipe 152 includes a first main gas supply pipe and a first branch gas supply pipe. The first main gas supply pipe is connected to the flash evaporator component 120. One end of the first branch gas supply pipe is connected to the first main gas supply pipe, and the other end is connected to the cooking pot 110. One first main gas supply pipe can be connected to one or more first branch gas supply pipes. The first valve body 170 is disposed on the first main gas supply pipe.

[0111] Example 13:

[0112] like Figure 1 As shown, based on Embodiments 1 to 12, the cooking appliance 100 further includes a second valve body 180, which is disposed on the second gas supply assembly 150. When the second valve body 180 is closed, the second gas supply assembly 150 is in a cut-off state, and when the second valve body 180 is open, the second gas supply assembly 150 is in a conducting state.

[0113] In this embodiment, the cooking appliance 100 also includes a second valve body 180, which is disposed in the second gas supply assembly 150 to control the opening and closing of the second gas supply assembly 150. In turn, in cooperation with the first gas supply assembly 140, the total amount of steam output in the cooking chamber can be controlled to achieve different cooking effects.

[0114] Specifically, the first valve body 170 and the second valve body 180 can be opened simultaneously, and both the first gas supply component 140 and the second gas supply component 150 can supply steam into the cooking cavity. Steam is discharged from multiple locations in the cooking cavity, improving the cooking effect.

[0115] The first valve body 170 can be closed while the second valve body 180 is opened simultaneously. The first gas supply component 140 cannot supply steam into the cooking cavity, while the second gas supply component 150 can supply steam into the cooking cavity. Thus, steam output at a specific location can be achieved through the second gas supply component 150 to achieve a specific cooking effect.

[0116] The second valve body 180 can be closed while the first valve body 170 is opened simultaneously. The second gas supply component 150 cannot supply steam into the cooking cavity, while the first gas supply component 140 can supply steam into the cooking cavity. Thus, steam output can be achieved through the first gas supply component 140 to achieve a specific cooking effect.

[0117] Example 14:

[0118] like Figure 1 As shown, based on Examples 10 to 13, the number of injection components 154 is further one or more.

[0119] In this embodiment, the number of injection components 154 can be one or more, the number of second gas delivery components 150 can be one or more, and the number of second valve bodies 180 can be one or more, with the second valve bodies 180 and the second gas delivery components 150 arranged in a one-to-one correspondence.

[0120] Specifically, the cooking appliance 100 includes a first valve body 170 and two second valve bodies 180, which can be opened simultaneously. The first gas supply component 140 and the second gas supply component 150 can both supply steam into the cooking cavity, and steam can be discharged from multiple locations in the cooking cavity to improve the cooking effect.

[0121] One first valve body 170 can be closed, and two second valve bodies 180 can be opened simultaneously. The first gas supply component 140 cannot supply steam into the cooking cavity, while the two second gas supply components 150 can supply steam into the cooking cavity. Thus, steam output at a specific location can be achieved through the second gas supply components 150 to achieve a specific cooking effect.

[0122] One first valve body 170 can be closed, one second valve body 180 can be closed, and another second valve body 180 can be opened. The first gas supply assembly 140 and one second gas supply assembly 150 cannot supply steam into the cooking cavity, while the other second gas supply assembly 150 can supply steam into the cooking cavity. Thus, steam output at a specific location can be achieved through the second gas supply assembly 150 to achieve a specific cooking effect.

[0123] One first valve body 170 can be opened, one second valve body 180 can be closed, and another second valve body 180 can be opened. One second gas supply component 150 cannot supply steam into the cooking cavity, while the first gas supply component 140 and the other second gas supply component 150 can supply steam into the cooking cavity. Thus, steam output at a specific location can be achieved through the second gas supply component 150 to achieve a specific cooking effect.

[0124] Furthermore, the flash evaporator assembly 120 has a continuous output state, that is, after a single release of steam, the switching valve 126 remains open and steam is continuously output; a pulse output state, that is, after a single release of steam, the switching valve 126 is closed, and the next release of steam is carried out according to parameters such as time, pressure or temperature; and a combination of the continuous output state and the pulse output state, that is, the above-mentioned continuous output state and pulse output state are combined and applied.

[0125] Example 15:

[0126] like Figure 1 As shown, based on Examples 10 to 14, the steam injection assembly 154 is further disposed at the upper part of the cooking cavity.

[0127] In this embodiment, the steam injection assembly 154 is positioned at the upper part of the cooking chamber, allowing steam to be directly injected onto the food through the steam injection assembly 154, thereby improving the cooking effect. Specifically, the cooking appliance 100 typically has a shelf that rests horizontally on the inner wall of the cooking pot 110. Furthermore, the shelf is positioned at a certain distance from both the top and bottom walls of the cooking pot 110. Therefore, the first air outlet of the first gas delivery assembly 140 is positioned below the shelf, and the steam injection assembly 154 is positioned above the shelf.

[0128] Specifically, the flash evaporator assembly 120 can be located at any position on the cooking appliance 100, specifically at the upper, lower, or middle part of the cooking inner pot 110. The cooking inner pot 110 is surrounded by a housing, and the flash evaporator assembly 120 is disposed between the cooking inner pot 110 and the housing.

[0129] The first air outlet of the first gas supply component 140 is located on the cooking chamber 110. It can be located at the upper or lower part of the cooking chamber 110. If it is located at the upper part, it can achieve low-oxygen steam cooking, that is, reduce the oxygen content in the cooking chamber and improve the cooking effect.

[0130] Example 16:

[0131] like Figure 2 As shown, in the cooking appliance 100 provided by the present invention, in the flash evaporator assembly 120, the infusion assembly 132 is connected to the input end of the container 122 via a bent pipe. A pressure relief valve 134, a heating element 124, a pressure sensor 1282, and a temperature sensor 1284 are installed on the container 122. A switch valve 126 is connected to the output end at the lower end of the container 122. Insulation material is wrapped around the outside of the container 122 to reduce heat loss and prevent the high-temperature container 122 from damaging other plastic parts of the cooking appliance 100.

[0132] The infusion assembly 132 injects water into container 122, where the water is heated and the pressure increases. Pressure sensor 1282 and temperature sensor 1284 detect the temperature and pressure inside container 122. When the set temperature and pressure are reached, the switch valve 126 opens, and a large amount of high-temperature water evaporates instantly into high-temperature steam under normal pressure.

[0133] like Figure 3As shown, in the flash evaporator assembly 120, the infusion assembly 132 is connected to a one-way valve 130 via a pipeline, and the one-way valve 130 is subsequently connected to a container 122. The one-way valve 130 allows water to flow into the receiving cavity of the container 122, and when there is high pressure in the receiving cavity, the one-way valve 130 can prevent steam or water from flowing back into the water pump. The heating element 124 is embedded in the bottom of the container 122, resulting in a larger high-temperature area and faster heating. The temperature sensor 1284 and the temperature controller 138 are mounted on the outside of the bottom of the container 122. The outlet of the container 122 is connected to a switch valve 126, which controls the discharge and cessation of steam.

[0134] In this embodiment, the infusion assembly 132 injects water into the container 122, where the water is heated and the pressure increases. Pressure sensor 1282 and temperature sensor 1284 detect the temperature and pressure within the container 122. Once the set temperature and pressure are reached, the switching valve 126 opens, and a large amount of high-temperature water evaporates instantly into high-temperature steam under normal pressure.

[0135] Among them, container 122 has a unique pressure-resistant structure. It heats water to a high temperature and high pressure state by storing heat, and can generate a large amount of steam and release it instantly when needed, so as to achieve the effect of "quick steaming and locking in freshness" for food 200, which can save cooking time.

[0136] The switching valve 126 is a high-pressure solenoid valve, which can be periodically controlled by a program to continuously input steam into the cooking cavity according to user needs, or to input steam in a directional, quantitative, and timed manner through the nozzles in the cooking cavity in a pulse form, so as to achieve "local fine steaming" and obtain better cooking results.
