The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order; the cold water mentioned in the specification and claims of this invention includes room temperature water.

[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Reference Figures 1 to 6The first embodiment of this application proposes a steam condensation system for a cooking device, which includes: a steam exhaust assembly 100, a condenser 200 and a drain assembly 300; the condenser 200 includes a steam inlet chamber 210, a plurality of condenser pipes 220, a plurality of heat sink assemblies 230 and a drain chamber 240.

[0037] One end of the exhaust assembly 100 is connected to the steam inlet chamber 210, and the other end is used to connect to the cavity of the cooking device; both ends of each condenser pipe 220 are connected to the steam inlet chamber 210 and the drain chamber 240 respectively; a number of condenser pipes 220 are arranged in an array at intervals, and each heat sink assembly 230 is attached between two adjacent condenser pipes 220; the outlet of the drain chamber 240 is connected to the drain assembly 300.

[0038] Furthermore, the heat sink assembly 230 is also attached to the outer side of the outermost condenser tube 220.

[0039] In this embodiment, after the cooking device is in operation, the cavity of the cooking device is filled with water vapor, which is then sequentially transferred to the exhaust assembly 100, the steam inlet chamber 210 of the condenser 200, and the condenser tube 220 of the condenser 200. Through the dispersed heat dissipation of multiple condenser tubes 220 and the auxiliary heat dissipation of the heat sink assembly 230, the water vapor in the condenser tube 220 is condensed into liquid, which then flows into the drain chamber 240 of the condenser 200. The drain chamber 240 transfers the collected liquid to the drain assembly 300, and finally the drain assembly 300 discharges the liquid in the drain chamber 240 to the outside of the cooking device or into a collector.

[0040] The steam condensation system for the cooking device uses an exhaust assembly 100 to transfer the water vapor generated inside the cooking device to the condenser 200. The condenser 200 then condenses and liquefies the water vapor into liquid. Finally, the drain assembly 300 discharges the liquid from the condenser 200 to the outside of the cooking device or into a collector, thus preventing the steam inside the cooking device from being directly discharged into the environment and avoiding increasing the humidity in the kitchen.

[0041] The steam inlet chamber 210 disperses the water vapor introduced by the exhaust assembly 100 into multiple condenser tubes 220. Simultaneously, the heat sink assembly 230 dissipates heat from the water vapor within the condenser tubes 220, aiding in the rapid liquefaction of the water vapor. The liquefied liquid is then discharged through the drain chamber 240 to the outside of the cooking appliance or into a collector. This not only improves the condensation speed of the condenser 200 but also further prevents steam from the cooking appliance from being directly released into the environment.

[0042] Furthermore, the axis of the condenser tube 220 can be a straight line or a curve. The cross-section of the condenser tube 220 can be circular, elliptical, square, or rectangular, etc.

[0043] Specifically, a number of condenser tubes 220 are arranged in a row, and there is a gap between any two condenser tubes 220.

[0044] Specifically, the condenser 200 is installed at the top of the cavity of the cooking appliance, such that the horizontal position of the steam inlet of the exhaust assembly 100 is lower than the horizontal position of the steam outlet, and the horizontal position of the water inlet of the drain assembly 300 is higher than the horizontal position of the water outlet. This allows the water condensed at the front end of the exhaust assembly 100 to flow smoothly back into the cavity, while keeping the water condensed by the condenser 200 at a high level, facilitating the natural downward discharge of the condensed water through the drain assembly 300.

[0045] In some embodiments, the steam inlet chamber 210 and the drain chamber 240 are located on the same side of the condenser tube 220 as a whole; correspondingly, the axis of the condenser tube 220 can be a curve, such that the steam inlet end and the water outlet end of the condenser tube 220 are located on the same side of the middle of the condenser tube 220.

[0046] Reference Figures 2 to 5 The condenser 200 further includes a transfer chamber 250; several condenser pipes 220 are divided into several condenser inlet pipes 221 and several condenser outlet pipes 222, and several heat sink assemblies 230 are divided into several first heat sink assemblies 231 and several second heat sink assemblies 232; several condenser inlet pipes 221 are arranged in an array at intervals, several condenser outlet pipes 222 are arranged in an array at intervals, and the two ends of each condenser inlet pipe 221 are respectively connected to the steam inlet chamber 210 and the transfer chamber 250, and the two ends of each condenser outlet pipe 222 are respectively connected to the transfer chamber 250 and the drain chamber 240; each first heat sink assembly 231 is attached between two adjacent condenser inlet pipes 221, and each second heat sink assembly 232 is attached between two adjacent condenser outlet pipes 222.

[0047] Furthermore, a first heat sink assembly 231 is also attached to the outer side of the outermost condensation inlet pipe 221, and a second heat sink assembly 232 is also attached to the outer side of the outermost condensation outlet pipe 222.

[0048] Specifically, the condensate inlet pipes 221 are arranged in a row with intervals, and below the lowest condensate inlet pipe 221, the condensate outlet pipes 222 are arranged in a row with intervals. This ensures that the inlet end of the condensate inlet pipe 221 and the outlet end of the condensate outlet pipe 222 are on the same side and respectively connected to the steam inlet chamber 210 and the drain chamber 240. The outlet end of the condensate inlet pipe 221 and the inlet end of the condensate outlet pipe 222 are on the same side and simultaneously connected to the transfer chamber 250. This ensures that the horizontal height of the steam inlet chamber 210 is higher than the horizontal height of the drain chamber 240.

[0049] join Figures 2 to 5 The ends of the first heat sink assembly 231 and the second heat sink assembly 232 extend along the axial direction of the condensation inlet pipe 221; a first heat sink assembly 231 is provided above the topmost condensation inlet pipe 221 and between any two condensation inlet pipes 221; a first heat sink assembly 231 or a second heat sink assembly 232 is provided between the lowest condensation inlet pipe 221 and the topmost condensation outlet pipe 222; a second heat sink assembly 232 is provided between any two condensation outlet pipes 222 and below the lowest condensation inlet pipe 221.

[0050] Both the condenser inlet tube 221 and the condenser outlet tube 222 are capillary condenser tubes 220.

[0051] Reference Figures 2 to 5 In some embodiments, there are 5 condenser inlet pipes 221 and 5 condenser outlet pipes 222.

[0052] In this embodiment, water vapor in the steam inlet chamber 210 is dispersed into each condenser inlet pipe 221. When the steam passes through the condenser inlet pipe 221, the first heat sink assembly 231 absorbs the heat from the condenser inlet pipe 221, creating a temperature difference between the inside and outside of the condenser inlet pipe 221. This causes the water vapor temperature in the condenser inlet pipe 221 to drop and condense, and then it is discharged into the transfer chamber 250. When the water vapor passes through the five upper condenser inlet pipes 221, some water vapor remains and has not completely condensed. The water vapor then enters the transfer chamber 250 and is dispersed into the five lower condenser outlet pipes 222, where it undergoes secondary condensation in conjunction with the second heat sink assembly 232. Under the pressure of the steam, the condensed water flows to the drain chamber 240, and the drain assembly 300 discharges the condensed water from the drain chamber 240 to the outside of the cooking device or into a collector.

[0053] In summary, by utilizing the condenser inlet pipe 221, the condenser outlet pipe 222, and the first heat sink assembly 231 and the second heat sink assembly 232 of the heat sink assembly 230, it is further ensured that the input water vapor can be completely condensed, thereby preventing the steam in the cooking device from being directly discharged into the environment and avoiding increasing the ambient humidity in the kitchen.

[0054] Furthermore, the condensed liquid and uncondensed water vapor discharged from the five condenser inlet pipes 221 are mixed using the transfer chamber 250 and then dispersed into the five condenser outlet pipes 222. This allows the condensed liquid to dissipate heat from the uncondensed water vapor, reducing the amount of uncondensed water vapor entering the condenser outlet pipes 222.

[0055] In some embodiments, the condensate inlet pipe 221 is also wavy along the axial direction, so that the input water vapor often hits the pipe wall of the condensate inlet pipe 221 and condenses; the condensate outlet pipe 222 is also wavy along the axial direction, so that the input water vapor often hits the pipe wall of the condensate outlet pipe 222 and condenses.

[0056] Reference Figures 2 to 5 The horizontal height of each of the condensate outlet pipes 222 is higher than the horizontal height of the outlet of the drain chamber 240.

[0057] In this embodiment, the condensed water can be drained quickly to avoid negative pressure caused by water accumulation.

[0058] Reference Figures 2 to 5 Furthermore, the steam inlet chamber 210 is provided with a steam inlet pipe 211 at its inlet, which connects to the exhaust assembly 100. The drain chamber 240 is provided with a drain pipe 241 at its outlet, which connects to the drain assembly 300. The outer wall of the steam inlet pipe 211 is provided with at least one first protruding ring 2111, which is press-fitted with the exhaust assembly 100, thus ensuring a sealed connection between the steam inlet pipe 211 and the exhaust assembly 100. The outer wall of the drain pipe 241 is provided with at least one second protruding ring 2411, which is press-fitted with the drain assembly 300, thus ensuring a sealed connection between the drain pipe 241 and the drain assembly 300.

[0059] Reference Figure 5 In some embodiments, a water guide plate 242 is provided inside the drainage chamber 240. The water guide plate 242 is inclined. The end of the water guide plate 242 at the higher horizontal position is located below the bottom wall of the outlet end of the lowest condensate outlet pipe 222. The end of the water guide plate 242 at the lower horizontal position is connected to the inner bottom wall of the drainage pipe 241. This ensures that the condensed water can be discharged quickly and completely, and further avoids negative pressure caused by water accumulation.

[0060] Reference Figure 1 and Figure 7 The exhaust assembly 100 includes an exhaust hood 110 and an exhaust pipe 120; the steam inlet of the exhaust hood 110 is used to connect to the cavity of the cooking device, and the two ends of the exhaust pipe 120 are respectively connected to the steam outlet 314 of the exhaust hood 110 and the steam inlet 210.

[0061] In this embodiment, the cavity of the cooking device is provided with multiple vent holes. The vent shroud 110 covers and connects all the vent holes, allowing the water vapor generated in the cavity of the cooking device to be discharged through the vent holes into the vent shroud 110 and then into the vent pipe 120. The vent shroud 110 is sealed to the vent holes, replacing the direct sealing between the vent pipe 120 and the vent holes. This avoids the need for the inlet end of the vent pipe 120 to be bent before sealing with the vent hole, which, without external force, can easily affect the sealing effect between the vent pipe 120 and the vent hole.

[0062] Reference Figure 1 , Figure 7 and Figure 8 The exhaust pipe 120 is a pipe body with multiple bends at different angles.

[0063] In this embodiment, when the water vapor discharged from the cavity of the cooking device passes through the multi-angle bend of the exhaust pipe 120, it can hit the pipe wall of the exhaust pipe 120 more often to generate condensation, thereby reducing the amount of steam before entering the condenser 200 and reducing the burden on the condenser 200.

[0064] Reference Figure 1 , Figure 7 and Figure 8 The drainage assembly 300 includes a three-way pipe 310 and a drain pipe 320. The three-way pipe 310 is provided with a through hole 311, a liquid inlet 312, a liquid outlet 313, and a steam outlet 314. The liquid inlet 312, the liquid outlet 313, and the steam outlet 314 are all connected to the through hole 311, and the steam outlet 314 is disposed upward at the top of the through hole 311. The liquid inlet 312 is connected to the outlet of the drainage chamber 240, the liquid outlet 313 is connected to the drain pipe 320, the steam outlet 314 is used to discharge the gas in the drainage chamber 240, and the drain pipe 320 is used to discharge the liquid in the drainage chamber 240.

[0065] In this embodiment, the through hole 311, liquid inlet 312, and liquid outlet 313 of the three-way pipe 310 ensure the connection between the drainage chamber 240 and the drainage pipe 320. Then, a steam outlet 314 is added to release the air in the drainage chamber 240 in advance, reduce the internal pressure in the drainage chamber 240, and facilitate the input of water vapor into the steam exhaust chamber.

[0066] Reference Figure 1 , Figure 7 and Figure 8The steam condensation system for the cooking device also includes a cooling fan 400, which is mounted on the condenser 200. The air outlet of the cooling fan 400 is directed toward each of the condenser pipes 220, each of the first heat sink assemblies 231 and each of the second heat sink assemblies 232.

[0067] In this embodiment, the cooling fan 400 blows air onto the condenser 200, so that the cold air blown out by the cooling fan 400 carries away the heat dissipated by the condenser 200 after passing over the surface of the condenser 200, thereby rapidly cooling the condenser 200 and achieving a cooling effect.

[0068] Specifically, the cooling fan 400 blows air onto the condenser inlet pipe 221, condenser outlet pipe 222, first heat sink assembly 231, and second heat sink assembly 232 to dissipate heat, thereby lowering the temperature of water vapor and causing condensation, thus further enhancing the condensation effect and further preventing the steam in the cooking device from being directly discharged into the environment, thus avoiding increasing the humidity in the kitchen.

[0069] Reference Figures 2 to 5 Both the first heat sink assembly 231 and the second heat sink assembly 232 have a single heat sink fin, which extends along the axial direction of the condenser tube 220; the heat sink fin is wavy.

[0070] In this embodiment, both the first heat sink assembly 231 and the second heat sink assembly 232 are wavy heat sink fins. At the same installation position, a longer first heat sink assembly 231 and second heat sink assembly 232 are installed to enhance the heat dissipation effect of the first heat sink assembly 231 and the second heat sink assembly 232, which facilitates the acceleration of the condensation effect of the condensation inlet pipe 221 and the condensation outlet pipe 222.

[0071] In other embodiments, both the first heat sink assembly 231 and the second heat sink assembly 232 include a plurality of heat sink fins, which are arranged in an array at intervals; each heat sink fin is wavy.

[0072] In this embodiment, the heat dissipation effect of the first heat sink assembly 231 and the second heat sink assembly 232 is enhanced, which facilitates the acceleration of the condensation effect of the condensation inlet pipe 221 and the condensation outlet pipe 222.

[0073] Reference Figures 7 to 9The second embodiment of this utility model provides a cooking device, which includes the steam condensation system for cooking devices described above. The cooking device also includes an outer shell, a cavity shell 500, a water tank 600, a water inlet assembly 700, a steam generator 800, and a steam delivery assembly 900. The water tank 600 is disposed in the outer shell. The water inlet assembly 700 is connected to the water tank 600 and the steam generator 800. The steam delivery assembly 900 is connected to the steam generator 800 and the cavity shell 500. The steam inlet of the exhaust assembly 100 is connected to the cavity shell 500.

[0074] Specifically, an installation cavity is formed between the outer shell and the cavity shell 500. The water tank 600, water inlet assembly 700, steam generator 800 and steam delivery assembly 900 are all located in the installation cavity. The steam condensation system for the cooking device is also located in the installation cavity.

[0075] Specifically, the condenser 200 is installed at the top of the outer wall of the cavity housing 500.

[0076] In this embodiment, an item to be heated is added into the cavity shell 500. Water tank 600, water inlet assembly 700, steam generator 800, and steam delivery assembly 900 provide steam to the cavity shell 500. The steam is used to heat the item. Then, the steam condensation system for the cooking device is used to discharge the steam after the heating process, so that the steam in the cavity shell 500 maintains a suitable temperature, ensuring that the heating process of the item is continuous and stable.

[0077] Furthermore, the steam condensation system for the cooking appliance uses the exhaust assembly 100 to transfer the steam generated inside the cavity shell 500 to the condenser 200, where the steam is condensed and liquefied into liquid. The drain assembly 300 then discharges the liquid from the condenser 200 to the outside of the cooking appliance or into a collector, thus preventing the steam inside the cavity shell 500 from being directly discharged into the environment and avoiding an increase in the humidity of the kitchen.

[0078] In some embodiments, the drain end of the drain assembly 300 is connected to the water tank 600.

[0079] In this embodiment, the water vapor discharged from the cavity shell 500 is condensed into liquid and returned to the water tank 600, thereby completing the water recycling.

[0080] Reference Figures 7 to 9 Specifically, the water inlet assembly 700 includes a first water inlet pipe 710, a water pump 720, and a second water inlet pipe 730. The two ends of the first water inlet pipe 710 are respectively connected to the water tank 600 and the water pump 720, and the two ends of the second water inlet pipe 730 are respectively connected to the water pump 720 and the steam generator 800.

[0081] Reference Figures 7 to 9 A steam delivery hole is provided at the bottom of the left or right side wall of the cavity shell 500, and the steam delivery assembly 900 is connected to the steam delivery hole.

[0082] Reference Figures 7 to 9 The exhaust port is located on the left or right side wall of the cavity shell 500. The horizontal height of the exhaust port is higher than that of the steam inlet. Correspondingly, the exhaust hood 110 is located on the side wall of the cavity shell 500 at the exhaust port. The condenser 200 and the cooling fan 400 are installed on the rear side wall of the cavity shell 500, or on the side wall opposite to the side wall of the cavity shell 500 at the exhaust port, which facilitates the installation of the extended multi-angle bent exhaust pipe 120.

[0083] Reference Figures 7 to 9 In some embodiments, the steam delivery assembly 900 includes a steam delivery hood 910 and a steam delivery pipe 920; the steam delivery hood 910 covers the steam delivery hole, and the steam delivery pipe 920 is connected to the steam generator 800 and the steam delivery hole respectively.
