Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0042] Hereinafter, a cooking appliance 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown, the cooking appliance 100 according to an embodiment of the present invention includes a cabinet assembly 1 , a water cup assembly 2 and a water cup cover 3 .

[0044] like Figure 1 and Figure 2 As shown, the cabinet assembly 1 defines a cooking space 11 . When a user uses the cooking appliance 100 , the user can put food into the cooking space 11 , and the cooking appliance 100 can process the food.

[0045] like Figure 1 、 Figure 3 and Figure 4 As shown, the water cup assembly 2 is arranged on the bottom wall of the cooking space 11. The water cup assembly 2 defines a accommodating cavity 21 with an open upper end. When the cooking utensil 100 has the function of steaming food, the cooking space 11 is heated, and the clean water in the water cup assembly 2 evaporates and generates high-temperature steam. The steam directly contacts the surface of the food through convection, and the heat penetrates deep into the interior through conduction, which can better retain the nutrition of the food.

[0046] like Figure 3 and Figure 4 As shown, the water cup cover 3 is arranged at the open opening of the accommodating cavity 21. A steam outlet 311 is provided on the water cup cover 3. The steam outlet 311 connects the accommodating cavity 21 and the cooking space 11. The water cup cover 3 can appropriately cover the open opening of the water cup assembly 2 to prevent the steam generated by the clean water in the accommodating cavity 21 from rushing straight upward, to prevent the food opposite to the open opening of the accommodating cavity 21 from being overcooked relative to the food at other positions in the cooking space 11, and to avoid affecting the quality of the food processed by the cooking utensil 100.

[0047] In the prior art, wet steam condenses into water droplets on the inner wall of the steamer and the surface of the food, which may drip onto the food, causing the food to absorb too much water (for example, the steamed buns collapse and the bun skin becomes sticky), resulting in nutrient loss or a poor taste.

[0048] In this embodiment, part of the steam generated by the clean water in the accommodating cavity 21 will hit the water cup cover 3 and then fall back into the accommodating cavity 21, thereby increasing the dryness of the steam in the cooking space 11; high-dryness steam can prevent condensed water from accumulating on some ingredients, ensuring that the ingredients are heated evenly.

[0049] For example, when steaming fish, high-dryness steam can ensure that the fish is cooked evenly inside and out, making it taste more tender.

[0050] According to the cooking appliance 100 of the embodiment of the present invention, the cup assembly 2 is positioned on the bottom wall of the cooking space 11, and the cup cover 3 is positioned over the opening of the upper-open accommodating cavity 21 defined by the cup assembly 2. The cup cover 3 is provided with a steam outlet 311, which connects the accommodating cavity 21 with the cooking space 11. The cup cover 3 can appropriately shield the opening of the cup assembly 2, preventing steam generated by the clear water in the accommodating cavity 21 from rushing upward, thereby preventing the food opposite the opening of the accommodating cavity 21 from being overcooked relative to food elsewhere in the cooking space 11 and thus affecting the quality of the food cooked by the cooking appliance 100. At the same time, the steam dryness in the cooking space 11 can be improved. The high-dryness steam can prevent condensation from accumulating on some of the food, ensuring that the food is heated evenly.

[0051] In this embodiment, the cooking appliance 100 may be a steamer or a steam oven having multiple functions such as steaming, baking, air frying, and fermentation.

[0052] In some embodiments of the present invention, Figure 7 and Figure 9 As shown, there are multiple steam outlets 311, and the multiple steam outlets 311 are arranged at intervals along the circumferential direction of the water cup cover 3, so that the steam generated by the clean water in the accommodating cavity 21 can enter the cooking space 11 respectively from the multiple steam outlets 311, and the multiple steam streams are separated, so that the steam distribution in the cooking space 11 is more uniform.

[0053] In some embodiments of the present invention, Figure 6 and Figure 8 As shown, the cup cover 3 has an upwardly projecting protrusion 312, and a steam outlet 311 is provided on the side wall of the protrusion 312. It is understood that the steam outlet 311 is provided on the side wall to prevent the steam outlet 311 from directly facing the top wall of the cooking space 11. This reduces the risk of condensed water in the cooking space 11 re-entering the accommodating cavity 21 through the steam outlet 311, prevents the condensed water from re-boiling to produce steam, and prevents the nitrate in the water from being decomposed into nitrite due to repeated high-temperature boiling. Nitrite is a potential carcinogen, and the health effects of nitrite ingestion can be minimized.

[0054] In some embodiments of the present invention, Figure 7 and Figure 8As shown, the steam outlet 311 is provided on at least one of the two side walls of the raised portion 312 along the circumferential direction of the cup cover 3. The area of ​​a single steam outlet 311 can be increased, thereby increasing the steam output of the cup assembly 2 and ensuring the steaming effect of the cooking device 100.

[0055] In some embodiments of the present invention, the raised portion 312 extends in the direction from the center of the cup cover 3 to the outer peripheral wall of the cup cover 3. One of the two directions of the circumferential direction of the cup cover 3 is an inclined direction. In the direction from the center of the cup cover 3 to the outer peripheral wall of the cup cover 3, the raised portion 312 is inclined toward the inclined direction. The steam outlet 311 is provided on the side of the raised portion 312 facing the inclined direction. While increasing the area of ​​the steam outlet 311, the steam in the accommodating cavity 21 is guided in the inclined direction, so that the steam in the cooking space 11 spirals upward in one direction, thereby increasing the steam coverage area.

[0056] In some embodiments of the present invention, Figure 7 As shown, the height of the protrusion 312 gradually increases from the center of the cup cover 3 to the outer peripheral wall of the cup cover 3, so that the area of ​​the steam outlet 311 gradually increases, thereby increasing the steam output of the steam outlet 311.

[0057] In some embodiments of the present invention, one end of the top wall of the raised portion 312 close to the steam outlet 311 is inclined upward, so that the steam in the accommodating cavity 21 rises upward under the guidance of the top wall, so that the high-temperature steam in the accommodating cavity 21 can enter the cooking space 11 more smoothly, thereby ensuring the steaming effect of the cooking utensil 100.

[0058] In some embodiments of the present invention, Figure 7 and Figure 9 As shown, the cup cover 3 includes a cover body 31 and a side panel 32. The cover body 31 is arranged at the open opening of the accommodating cavity 21. The cover body 31 is provided with a steam outlet 311. The side panel 32 is arranged at the lower end of the cover body 31 and is connected to the cover body 31. The outer wall of the side panel 32 is flush with the outer peripheral wall of the cover body 31. A notch 321 is provided on the side panel 32. The notch 321 connects the accommodating cavity 21 and the cooking space 11. Condensed water in the cooking space 11 can enter the accommodating cavity 21 through the notch 321, thereby avoiding excessive humidity in the cooking space 11 and affecting the quality of food.

[0059] In some embodiments of the present invention, Figure 7 and Figure 9 As shown, there are multiple notches 321 spaced apart along the circumferential direction of the cover body 31. Condensed water can enter the accommodating cavity 21 from the multiple notches 321 in the circumferential direction of the cover body 31, which can better ensure the steam dryness of the cooking space 11, avoid the accumulation of condensed water on some food materials, and ensure that the food materials are heated evenly.

[0060] In some embodiments of the present invention, Figure 4 and Figure 9 As shown, a partition 22 is provided in the accommodating chamber 21, and the partition 22 divides the accommodating chamber 21 into a first chamber 211 and a second chamber 212. The steam outlet 311 is connected to the first chamber 211, and the second chamber 212 is arranged around the first chamber 211. The notch 321 can be connected to the second chamber 212, which can prevent the condensed water from entering the cooking space 11 from the steam outlet 311 after reheating, and prevent the nitrate in the water from being decomposed into nitrite due to repeated boiling at high temperature. Nitrite is a potential carcinogen, and the impact on the health of users who ingest nitrite can be avoided as much as possible.

[0061] In some embodiments of the present invention, Figure 3 As shown, the cooking appliance 100 also includes a spray assembly 4, located at the upper end of the cooking space 11, for spraying liquid into the cooking space 11. The water cup assembly 2 is provided with a first outlet pipe 23, which communicates with both the accommodating cavity 21 and the spray assembly 4. It will be appreciated that after the cooking process of the cooking appliance 100 is completed, it can enter a cleaning mode. The first outlet pipe 23 directs the liquid in the accommodating cavity 21 to the spray assembly 4, which then sprays the liquid into the cooking space 11 for cleaning. The cleaned wastewater can enter the accommodating cavity 21 through the notch 321 for collection. The first outlet pipe 23 can be located on the bottom wall or the peripheral wall of the water cup assembly 2.

[0062] A spray port 13 is provided at the upper end of the cooking space 11 , and the spray assembly 4 is opposite to the spray port 13 to achieve cleaning of the cooking space 11 .

[0063] In this embodiment, if Figure 3 As shown, the first outlet pipe 23 is a three-way pipe that is connected to the first chamber 211, the second chamber 212, and the spray assembly 4. During the cleaning process, a cleaning block can be added to the first chamber 211. The liquid in the first chamber 211 enters the spray assembly 4 and is sprayed into the cooking space 11, thereby cleaning the cooking space 11. The wastewater from the cleaned cooking space 11 enters the second chamber 212 through the notch 321, thereby collecting the wastewater.

[0064] In some embodiments of the present invention, Figure 3 As shown, the cooking utensil 100 further includes a circulation pump 5 , which is connected to both the first outlet pipe 23 and the spray assembly 4 , so as to pump the liquid in the accommodating cavity 21 to the spray assembly 4 , thereby cleaning the cooking utensil 100 .

[0065] In this embodiment, if Figure 3As shown, the first outlet pipe 23 is a three-way pipe that is connected to the first chamber 211, the second chamber 212, and the circulation pump 5. The circulation pump 5 is connected to the spray assembly 4. During the cleaning process, a cleaning block can be added to the first chamber 211. The liquid in the first chamber 211 enters the spray assembly 4 and is sprayed into the cooking space 11, thereby cleaning the cooking space 11. The wastewater from the cleaned cooking space 11 enters the second chamber 212 through the gap 321, thereby collecting the wastewater. The water in the second chamber 212 can be pumped again by the circulation pump 5 to the spray assembly 4 to clean the cooking space 11 again, achieving water-saving cleaning of the cooking space 11. Clean water is then re-introduced from the first chamber 211 to circulate the cleaning of the cooking space 11. If a high degree of cleanliness is required, repeating the rinse multiple times will achieve better results.

[0066] In some embodiments of the present invention, Figure 3 As shown, the water cup assembly 2 is provided with a second outlet pipe 24, which is in communication with the accommodating chamber 21 and is used to direct the liquid in the accommodating chamber 21 out of the cooking appliance 100. This can achieve drainage of wastewater in the accommodating chamber 21 and prevent the accumulation of wastewater in the water cup assembly 2, which can cause bacterial growth and other problems. The second outlet pipe 24 can be provided on the bottom wall or the peripheral wall of the water cup assembly 2.

[0067] In this embodiment, if Figure 3 As shown, the second outlet pipe 24 is a three-way pipe, and the second outlet pipe 24 is connected to both the first chamber 211 and the second chamber 212. During the sewage discharge process, the residual water in the first chamber 211 and the sewage in the second chamber 212 can be discharged from the second outlet pipe 24, avoiding the problem of bacteria growth caused by the sewage and residual water being retained in the water cup assembly 2.

[0068] In some embodiments of the present invention, Figure 3 As shown, the cooking utensil 100 also includes a drainage pump 6, which is arranged outside the water cup assembly 2 and is connected to the second outlet pipe 24, so as to facilitate pumping the liquid in the accommodating cavity 21 out of the cooking utensil 100, thereby avoiding problems such as bacterial growth caused by sewage and residual water remaining in the water cup assembly 2.

[0069] In this embodiment, if Figure 3 As shown, the second outlet pipe 24 is a three-way pipe, and the second outlet pipe 24 is connected to the first chamber 211, the second chamber 212, and the drain pump 6. During the drainage process, the drain pump 6 can pump out the residual water in the first chamber 211 and the sewage in the second chamber 212 through the second outlet pipe 24, avoiding the problem of bacteria growth caused by the sewage and residual water being retained in the water cup assembly 2.

[0070] In some embodiments of the present invention, Figure 3As shown, the water cup assembly 2 is provided with a first inlet pipe 25, which is in communication with the first cavity 211 and is used to introduce clean water into the first cavity 211, thereby replenishing the cooking appliance 100 with water during the steaming and cleaning processes.

[0086] The cooking appliance 100 is a steam oven. When the steam oven is in the steam function mode:

[0087] The clean water required for the steam function can be obtained from the water tank 8 or connected to the water purifier 9. If the water source is obtained from the water tank 8, the clean water is pumped to the first chamber 211 through the water pump 10; if the water source is the water purifier 9, the clean water is drained to the first chamber 211 through the water pump 10 or the valve body 101.

[0088] After the clean water enters the first chamber 211, the first heating element 7 begins to heat and generate steam. The steam rotates and dissipates into the cooking space 11 through the six spiral steam outlets 311 of the cover body 31, thereby heating the food on the baking tray and the steam rack. The water vapor generated at the beginning of the steaming hits the cover body 31 and at least partially flows back into the first chamber 211, thereby increasing the dryness of the steam.

[0089] The condensed water generated when the steam hits the peripheral wall of the cooking space 11 and other components on the peripheral wall enters the second cavity 212 through the notch 321 on the side plate 32, and is discharged to the drainage pump 6 through the tee of the second outlet pipe 24 after the steam mode ends.

[0090] like Figure 2 and Figure 5 As shown, the cooking appliance 100 is a steam oven. When the steam oven is in the automatic cleaning mode:

[0091] The clean water required for the cleaning function can be obtained from the water tank 8 or connected to the water purifier 9. If the water source is obtained from the water tank 8, the clean water is pumped to the first chamber 211 through the water pump 10; if the water source is the water purifier 9, the clean water is drained to the first chamber 211 through the water pump 10 or the valve body 101.

[0092] Step 1: After the clean water enters the first chamber 211, the first heating element 7 starts to heat and generate hot water, so that the temperature of the hot water is maintained in the range of 50-70°C for easy cleaning. Before cleaning, the consumables required for cleaning can be put into the first chamber 211. After the consumables are fully dissolved and mixed, the circulation pump 5 works to pump the hot water in the first chamber 211 to the spray assembly 4. The hot water rotates through the nozzle of the spray assembly 4 through the inner wall of the cooking space 11 and the middle accessories, and the sewage flows back to the condensation chamber. The circulation pump 5 then pumps water from the second chamber 212 to the spray assembly 4. After this repeated cycle cleaning until the inner wall of the cooking space 11 is clean, the sewage is discharged through the drainage pump 6.

[0093] Step 2: Re-fill with clean water, do not heat the first heating element 7, circulate and rinse once and then drain. If a high degree of cleanliness is required, repeat the rinse several times for better results.
