Description

Technical Field

[0001] This invention relates to the field of steam condensation technology, and in particular to a condensation structure and a steam baking device. Background Technology

[0002] To improve the utilization of kitchen space, kitchen appliances on the market are becoming increasingly integrated. The emergence of steam ovens represents the integration of steamers and ovens, effectively reducing the kitchen area occupied. They can not only steam and bake, but also defrost and ferment, making them more suitable for daily use.

[0003] Currently, steam ovens on the market often exhaust steam generated during cooking directly to the outside through the heat dissipation system via the heat dissipation duct. The temperature of the exhaust port is very high, which can easily burn users and has a low safety factor. Summary of the Invention

[0004] To address the problem that current steam ovens on the market often exhaust steam directly to the outside through the air ducts during cooking, resulting in very high temperatures at the exhaust ports that can easily burn users and pose a low safety factor, this invention provides a condensation structure and a steam oven device.

[0005] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is to provide a condensing structure, which includes a shell, a steam guide pipe, a steam outlet cap, and a fan. One end of the shell has a mixing chamber, and the other end has a steam inlet and a steam outlet. The steam outlet cap is disposed in the mixing chamber, and the fan is mounted on the mixing chamber. A spiral structure is provided inside the shell, forming a spiral channel. One end of the spiral channel communicates with the mixing chamber, and the other end communicates with the steam outlet. The steam guide pipe is sleeved within the spiral structure along the spiral axis, with one end communicating with the steam inlet and the other end communicating with the steam outlet cap. Hot steam enters the steam guide pipe through the steam inlet and is ejected from the steam outlet cap. It then collides and mixes with the cold air generated by the fan in the mixing chamber for cooling before being discharged from the steam outlet through the spiral channel.

[0006] In one embodiment, the housing includes a detachably connected front shell and a rear shell, and the spiral structure includes a plurality of first partitions and a plurality of second partitions, the first partitions being disposed inside the front shell and the second partitions being disposed inside the rear shell, with adjacent first partitions and second partitions connected end to end to define the spiral channel.

[0007] In one embodiment, the first partition has a first notch, the second partition has a second notch, the first notch and the second notch define an accommodating space, and the steam pipe is disposed in the accommodating space.

[0008] In one embodiment, a drainage side groove is provided on the inner sidewall at the connection between the front shell and the rear shell, and the drainage side groove is connected to the exhaust port.

[0009] In one embodiment, the condensation structure further includes a sealing strip disposed at the junction of the front shell and the rear shell.

[0010] In one embodiment, the steam outlet cap is placed on the central axis of the fan, and one end of the steam outlet cap is connected to the steam guide pipe, while the other end abuts against the fan.

[0011] In one embodiment, the helical direction of the helical structure is the same as the helical direction of the fan blades.

[0012] In one embodiment, the steam outlet cover is provided with a spiral rib for spiraling out heating steam, the spiral direction of the spiral rib being opposite to the spiral direction of the fan blades.

[0013] In one embodiment, the housing is a silicone housing or a metal housing.

[0014] To solve the above-mentioned technical problems, the present invention also provides a steam baking device, which includes a main body and the aforementioned condensation structure. The main body includes a heat dissipation duct for discharging hot steam, and the steam inlet is connected to the air outlet of the heat dissipation duct.

[0015] Compared with the prior art, the condensation structure and steam-baking equipment provided in this embodiment of the invention have the following advantages:

[0016] 1. In the condensing structure provided in this embodiment of the invention, a mixing chamber is provided at one end of the shell, and a steam inlet and a steam outlet are provided at the other end. A steam outlet cap is located in the mixing chamber, and a fan cover is located on the mixing chamber. A spiral structure is provided inside the shell, forming a spiral channel. One end of the spiral channel is connected to the mixing chamber, and the other end is connected to the steam outlet. A steam guide pipe is sleeved inside the spiral structure along the spiral axis, with one end connected to the steam inlet and the other end connected to the steam outlet cap. With this arrangement, hot steam enters the steam guide pipe through the steam inlet and is ejected from the steam outlet cap to the mixing chamber. Since the steam outlet cap is located in the mixing chamber and the fan cover is located on the mixing chamber, the cold air generated by the fan will collide and mix with the hot steam ejected from the steam outlet cap to achieve cooling. Subsequently, the mixed steam is pressed into the spiral channel, where it collides with the inner wall of the spiral channel and condenses to form condensate. Finally, the cooled steam and the condensate are discharged through the steam outlet. This invention solves the problem that steam generated during cooking in conventional steam ovens is often directly discharged outwards through the air duct by the heat dissipation system, resulting in very high temperatures at the exhaust port that can easily burn users and have a low safety factor. It enables rapid condensation of hot steam, preventing users from being burned when steam is discharged and improving the safety of using the steam oven.

[0017] Furthermore, since the steam guide pipe is fitted inside the spiral structure along its helical axis, the temperature inside the spiral channel is lower than that inside the steam guide pipe. Therefore, the hot steam undergoes initial cooling as it flows through the steam guide pipe. As the fan continuously generates cold air that collides and mixes with the hot steam and forces it into the spiral channel, the steam undergoes secondary cooling as it flows within the spiral channel. These two cooling processes improve the steam's cooling efficiency, with the initial cooling facilitating rapid condensation during the secondary cooling.

[0018] In addition, the steam inlet and outlet are located at the same end of the shell, and the steam guide pipe is sleeved inside the spiral structure along the spiral axis. The ingenious design of the steam guide pipe and the spiral structure allows the hot steam to flow from one end of the shell to the other end along the steam guide pipe, and then flow back from the other end of the shell along the spiral channel. This increases the steam travel distance in the case of limited space, greatly reduces the volume of the condensation structure, makes full use of the limited space inside the steam oven, and improves the space utilization rate inside the steam oven.

[0019] 2. In the condensing structure provided in this embodiment of the invention, the shell includes a detachably connected front shell and a rear shell. The spiral structure includes multiple first baffles and multiple second baffles. The first baffles are disposed inside the front shell, and the second baffles are disposed inside the rear shell. Adjacent first and second baffles are connected end-to-end to define a spiral channel. By providing a detachable connection between the front and rear shells, the assembly of the steam pipe and subsequent cleaning and maintenance of the condensing structure are facilitated. By connecting the multiple first baffles of the front shell and the multiple second baffles of the rear shell end-to-end to form a spiral channel inside the shell, the manufacturing process is simple and convenient, which helps to improve the production efficiency of the condensing structure.

[0020] 3. In the condensation structure provided in this embodiment of the invention, a first notch is provided on the first partition plate, and a second notch is provided on the second partition plate. The first and second notches define an accommodating space, in which the steam guide pipe is disposed. By providing the first and second notches, when the steam guide pipe is positioned between the first and second notches, the spiral structure and the steam guide pipe work together to form a spiral channel. This allows the steam guide pipe to be fitted inside the spiral structure along its spiral axis while ensuring normal steam flow within the spiral channel.

[0021] 4. In the condensation structure provided in this embodiment of the invention, a drainage side groove is provided on the inner wall of the connection between the front shell and the rear shell, and the drainage side groove is connected to the exhaust port. By providing the drainage side groove, the condensate formed by the collision of steam and the inner wall of the spiral channel is partially discharged through the spiral channel to the exhaust port under the action of its own gravity and the air flow in the channel, and part of it flows to the bottom through the drainage side groove and then flows out from the exhaust port, thereby accelerating the discharge efficiency of condensate in the condensation structure.

[0022] 5. In the condensation structure provided in this embodiment of the invention, the condensation structure further includes a sealing strip, which is disposed at the connection between the front shell and the rear shell. Since there will be gaps at the joint after the front shell and the rear shell are spliced, by setting a sealing strip at the connection between the front shell and the rear shell, the airtightness of the spiral channel can be improved, preventing steam from escaping from the gaps.

[0023] 6. In the condensing structure provided in this embodiment of the invention, the steam outlet cap is placed on the central axis of the fan, with one end connected to the steam guide pipe and the other end abutting against the fan. Since the middle position of the fan is a windless zone during operation, placing the steam outlet cap on the central axis of the fan can minimize the impact of the fan on the hot steam ejected from the steam outlet cap. Simultaneously, the steam outlet cap abutting against the fan can prevent it from detaching from the steam guide pipe due to the force generated when steam is ejected.

[0024] 7. In the condensation structure provided in this embodiment of the invention, the spiral direction of the spiral structure is the same as the spiral direction of the fan blades, which can ensure that the hot steam ejected from the steam outlet cover collides and mixes with the cold air generated by the fan, and then enters the spiral channel under the action of the fan's air pressure.

[0025] 8. In the condensation structure provided in this embodiment of the invention, the steam outlet cap is provided with a spiral bone for spirally ejecting heated steam. The spiral direction of the spiral bone is opposite to the spiral direction of the fan blades. By setting the spiral bone, the heated steam is ejected in a spiral manner. By setting the spiral direction of the spiral bone to be opposite to the spiral direction of the fan blades, the direction of the heated steam ejected from the steam outlet cap is exactly opposite to the direction of the cold air. At this time, collision can occur, and it can be fully mixed with the cold air to achieve rapid condensation.

[0026] 9. In the condensation structure provided in this embodiment of the invention, the shell is a silicone shell or a metal shell. By using a silicone shell, the adhesive properties of the silicone surface allow the condensate generated by the condensation of hot gas to adhere to the wall surface of the spiral channel, making it easier for steam to condense into water droplets as it flows through the spiral channel. By using a metal shell, the heat dissipation efficiency of the steam can be improved, accelerating condensation.

[0027] 10. The steam-roasting equipment provided in this embodiment of the invention has the same function as the condensation structure described above, and will not be repeated here. Attached Figure Description

[0054] Example 1

[0055] Please combine Figures 1-3 As shown, the first embodiment of the present invention provides a condensation structure 1 for rapid condensation of high-temperature hot steam, which can be applied in a steam oven to rapidly condense the high-temperature hot steam generated during cooking. The condensation structure 1 includes a shell 11, a steam guide pipe 12, a steam outlet cap 13, and a fan 14.

[0056] The shell 11 is hollow inside and is roughly cylindrical, divided into three sections along its length: a mixing section 111, a condensing section 112, and a steam inlet / outlet section 113. The mixing section 111 and the steam inlet / outlet section 113 are located at opposite ends of the shell 11, and the condensing section 112 is located between the mixing section 111 and the steam inlet / outlet section 113. Specifically, the mixing section 111 of the shell 11 has a mixing chamber 1111, a steam outlet cap 13 is located in the mixing chamber 1111, and a fan 14 is placed over the mixing chamber 1111 to allow the cold air generated by the fan 14 to enter the mixing chamber 1111.

[0057] The steam inlet and outlet section 113 of the shell 11 has a steam inlet 1131 and a steam outlet 1132. The steam inlet 1131 is used to supply heating steam, and the steam outlet 1132 is used to discharge cooled steam and condensate. Specifically, the steam inlet 1131 and the steam outlet 1132 are located on the side of the steam inlet and outlet section 113.

[0058] A spiral structure 114 is provided in the condensation section 112 of the shell 11. The spiral structure 114 forms a spiral channel 1141. One end of the spiral channel 1141 is connected to the mixing chamber 1111, and the other end is connected to the exhaust port 1132.

[0059] The steam guide pipe 12 is an L-shaped pipe, which passes through the steam inlet / outlet section 113 and the condensation section 112. Specifically, the steam guide pipe 12 is sleeved inside the spiral structure 114 along the spiral axis. One end of the steam guide pipe 12 is connected to the steam inlet 1131, and the other end is connected to the steam outlet cap 13. Hot steam enters the steam guide pipe 12 through the steam inlet 1131 and is ejected from the steam outlet cap 13. It then collides and mixes with the cold air generated by the blower 14 in the mixing chamber 1111 for cooling before being discharged from the exhaust port 1132 through the spiral channel 1141.

[0060] Optionally, the housing 11 can be a silicone shell or a metal shell. By using a silicone shell, the adhesive properties of the silicone surface allow condensate to adhere to the walls of the spiral channel 1141, making it easier for steam to condense into water droplets as it flows through the spiral channel 1141. Using a metal shell improves the heat dissipation efficiency of the steam and accelerates condensation.

[0061] Optionally, the steam guide pipe 12 can be a silicone tube or a metal tube. Using a silicone tube improves the airtightness of the fit between the steam guide pipe 12 and the spiral structure 114. Using a metal tube improves the heat dissipation efficiency of the steam, causing the temperature of the hot steam to drop further when it exits the steam outlet cap 13, thus achieving rapid condensation after colliding and mixing with the cold air.

[0062] In this embodiment of the invention, the fan 14 is a high-speed fan. The fan 14 is locked to the housing 11 by a fixing member 15 to cover the mixing chamber 1111. Optionally, the fixing member 15 can be a screw, adhesive, magnet, or snap-fit. In this embodiment of the invention, the fixing member 15 is a screw.

[0063] In this embodiment of the invention, hot steam enters the steam guide pipe 12 through the steam inlet 1131 and is then ejected from the steam outlet cap 13 into the mixing chamber 1111. Since the steam outlet cap 13 is located in the mixing chamber 1111 and the fan 14 is mounted on the mixing chamber 1111, the cold air generated by the fan 14 collides and mixes with the hot steam ejected from the steam outlet cap 13 to achieve cooling. Subsequently, the mixed steam is pressed into the spiral channel 1141, where it collides with the inner wall of the spiral channel 1141 and condenses to form condensate. Finally, the cooled steam and the condensate are discharged through the exhaust port 1132. This invention solves the problem that steam generated during cooking in commercially available steam ovens is often directly discharged through the air duct by the heat dissipation system, resulting in very high exhaust temperatures that can easily burn users and have a low safety factor. This invention enables rapid condensation of hot steam, preventing burns to users when steam is discharged and improving the safety of using the steam oven. Furthermore, since the steam guide pipe 12 is fitted inside the spiral structure 114 along the spiral axis, the temperature inside the spiral channel 1141 is lower than the temperature inside the steam guide pipe 12. Therefore, the hot steam undergoes initial cooling when flowing through the steam guide pipe 12. Because the fan 14 continuously generates cold air that collides and mixes with the hot steam and forces it into the spiral channel 1141, the steam undergoes secondary cooling as it flows within the spiral channel 1141. These two cooling processes improve the steam's cooling efficiency, and the initial cooling facilitates rapid condensation of the steam during the secondary cooling. Furthermore, the steam inlet 1131 and the steam outlet 1132 are located at the same end of the shell 11, and the steam guide pipe 12 is sleeved inside the spiral structure 114 along the spiral axis direction. The ingenious design of the steam guide pipe 12 and the spiral structure 114 allows the hot steam to flow from one end of the shell 11 to the other end along the steam guide pipe 12, and then flow back from the other end of the shell 11 along the spiral channel 1141. This increases the steam travel distance under limited space conditions, greatly reduces the volume of the condenser structure 1, makes full use of the limited space inside the steam oven, and improves the space utilization rate inside the steam oven.

[0064] Please combine Figures 2-5As shown, specifically, the housing 11 includes a front housing 115 and a rear housing 116, which are detachably connected, specifically by snap-fit ​​or adhesive.

[0065] Specifically, the spiral structure 114 includes a plurality of first partitions 1151 and a plurality of second partitions 1161. The first partitions 1151 are inclinedly disposed on the inner sidewall of the front shell 115, and the second partitions 1161 are inclinedly disposed on the inner sidewall of the rear shell 116. When the front shell 115 and the rear shell 116 are connected, the adjacent first partitions 1151 and second partitions 1161 are connected end to end to define the spiral channel 1141, that is, the end of the first first partition 1151 on the front shell 115 and the end of the first second partition on the rear shell 116 are connected. The first end of 1161 is connected to the first end of the second partition 1151 on the front shell 115, the second end of the second partition 1151 is connected to the first end of the second partition 1161 on the rear shell 116, the second end of the second partition 1161 is connected to the first end of the third partition 1151 on the front shell 115, and so on. After all the first partitions 1151 and second partitions 1161 are connected, a spiral channel 1141 is formed.

[0066] In this embodiment of the invention, the front shell 115 and the rear shell 116 are detachably connected, facilitating the assembly of the steam pipe 12 and the subsequent cleaning and maintenance of the condensation structure 1. Simultaneously, by connecting the multiple first partitions 1151 of the front shell 115 and the multiple second partitions 1161 of the rear shell 116 end-to-end to form the spiral channel 1141 inside the shell 11, the manufacturing process is simple and convenient, which helps to improve the production efficiency of the condensation structure 1.

[0067] Please combine Figures 2-6 As shown, specifically, a first notch 1152 is provided on the first partition 1151, and a second notch 1162 is provided on the second partition 1161. When the front shell 115 and the rear shell 116 are connected, all the first partitions 1151 and the second partitions 1161 are connected end to end to form a spiral channel 1141. Adjacent first notches 1152 and second notches 1162 are staggered to define a receiving space q. The receiving space q extends along the length direction of the shell 11, and the steam pipe 12 is provided in the receiving space q.

[0068] More specifically, the outer wall contour of the steam pipe 12 matches the shape and size of the first notch 1152 and the second notch 1162, so that the steam pipe 12 fits tightly against the first notch 1152 and the second notch 1162, ensuring the airtightness of the spiral channel 1141.

[0069] In this embodiment of the invention, by setting a first notch 1152 and a second notch 1162, when the steam pipe 12 is positioned between the first notch 1152 and the second notch 1162, the spiral structure 114 and the steam pipe 12 cooperate to form a spiral channel 1141. This not only allows the steam pipe 12 to be fitted inside the spiral structure 114 along the spiral axis direction, but also ensures that steam flows normally in the spiral channel 1141.

[0070] Please combine Figure 2 , Figure 7 and Figure 8 As shown, the condensation structure 1 further includes a sealing strip 16, which is a U-shaped sealing strip. The sealing strip 16 is disposed at the connection between the front shell 115 and the rear shell 116. Specifically, the sealing strip 16 is embedded inside the connection between the front shell 115 and the rear shell 116.

[0071] It is understandable that after the front shell 115 and the rear shell 116 are spliced ​​together, there will be gaps at the splice. By setting a sealing strip 16 at the connection between the front shell 115 and the rear shell 116, the airtightness of the spiral channel 1141 can be improved, preventing steam from escaping from the gaps.

[0072] Please combine Figure 8 and Figure 9 As shown, a drainage side groove 117 is further provided on the inner wall of the connection between the front shell 115 and the rear shell 116, and the drainage side groove 117 is connected to the exhaust port 1132. By providing the drainage side groove 117, the condensate formed by the collision of steam with the inner wall of the spiral channel 1141 is partially discharged from the exhaust port 1132 through the spiral channel 1141 under the action of its own gravity and the air flow in the channel, and part of it flows to the bottom through the drainage side groove 117 and flows out from the exhaust port 1132, thereby accelerating the discharge efficiency of condensate in the condensation structure 1.

[0073] Please continue reading. Figure 8 As shown, Figure 8 The dashed line A shown is the central axis of fan 14. Figure 8 The dashed line B shown is the helical axis of the helical structure 114.

[0074] Specifically, the steam outlet cap 13 is placed on the central axis A of the blower 14, and one end of the steam outlet cap 13 is connected to the steam guide pipe 12, while the other end abuts against the blower 14.

[0075] It is understandable that, since the middle position of the blower 14 is a windless zone, placing the steam outlet cap 13 on the central axis A of the blower 14 can minimize the impact of the blower 14 on the hot steam ejected from the steam outlet cap 13. At the same time, the steam outlet cap 13 abutting against the blower 14 can prevent the steam outlet cap 13 from detaching from the steam guide pipe 12 due to the force generated when the steam is ejected.

[0076] Furthermore, the steam outlet cap 13 is rotatably connected to the steam guide pipe 12, so that the steam outlet cap 13 is rotated under force when hot steam is ejected, thereby fully stirring and mixing the hot steam and cold air in the mixing chamber 1111 and accelerating the condensation effect of the steam.

[0077] In this embodiment of the invention, the central axis A of the fan 14 coincides with the spiral shaft B of the spiral structure 114, which can ensure that the steam flows evenly inside the condensing structure 1 and avoid uneven force inside the condensing structure 1 caused by excessive or insufficient gas pressure on one side.

[0078] Please combine Figures 10-13 As shown, specifically, the fan 14 includes a spirally arranged fan blade 141. The spiral direction of the spiral structure 114 is the same as the spiral direction of the fan blade 141 of the fan 14, which can ensure that the hot steam ejected from the steam outlet cover 13 collides and mixes with the cold air generated by the fan 14, and then enters the spiral channel 1141 under the action of the wind pressure of the fan 14.

[0079] In this embodiment of the invention, the helical direction of the helical structure 114 and the helical direction of the fan blade 141 of the fan 14 are both positive helices.

[0080] Specifically, the steam outlet cover 13 is provided with a spiral bone 131 for the spiral ejection of heating steam, and the spiral direction of the spiral bone 131 is opposite to the spiral direction of the fan blade 141 of the blower 14.

[0081] In this embodiment of the invention, the spiral direction of the spiral bone 131 is anti-spiral.

[0082] In this embodiment of the invention, by setting the spiral bone 131, the hot steam is ejected in a spiral manner. By setting the spiral direction of the spiral bone 131 to be opposite to the spiral direction of the fan blades 141 of the blower 14, the direction of the hot steam ejected from the steam outlet cover 13 is exactly opposite to the direction of the cold air. At this time, collision can occur, and the steam can be fully mixed with the cold air to achieve rapid condensation.

[0083] Please continue reading. Figure 13As shown, for ease of understanding, the process of steam condensation in the condensing structure 1 is described here in this embodiment of the invention. In use, high-temperature steam a enters the steam guide pipe 12 from the steam inlet 1131 and flows along the extension direction of the steam guide pipe 12 to the steam outlet cap 13. During its flow within the steam guide pipe 12, it undergoes initial cooling, resulting in slightly lower steam temperature when ejected from the steam outlet cap 13. Under the action of the spiral bone 131 of the steam outlet cap 13, the high-temperature steam a spirally ejects into the mixing chamber 1111. The fan 14 continuously operates and draws cold air e from the outside into the mixing chamber 1111. Since the spiral direction of the spiral bone 131 is opposite to the spiral direction of the fan blades 141 of the fan 14, the high-temperature steam a, when spirally ejected from the spiral bone 131, collides with the cold air e and mixes thoroughly to form medium-high temperature steam b. Since the spiral direction of the spiral structure 114 is the same as the spiral direction of the fan blades 141 of the blower 14, the mixed medium-high temperature steam b enters the spiral channel 1141 of the spiral structure 114 under the action of the blower 14. As the medium-high temperature steam b flows through the spiral channel 1141, it further cools to form medium-temperature gas c, which condenses upon collision with the inner wall of the spiral channel 1141 to form condensate f. The medium-temperature gas c continues to flow along the spiral channel 1141 for further cooling, finally forming low-temperature gas d which is discharged to the outside from the exhaust port 1132. Under the influence of its own gravity and the airflow within the spiral channel 1141, part of the condensate f flows out of the exhaust port 1132 through the spiral channel 1141, and part flows to the bottom through the drainage side groove 117 and out of the exhaust port 1132.

The main body 21 includes a heat dissipation duct 211 for discharging hot steam, and the steam inlet 1131 is connected to the air outlet of the heat dissipation duct 211.

[0086] In this embodiment of the invention, by using the condensing structure 1 in Embodiment 1 as the condensing device of the steam-grilling equipment 2, the hot steam generated by the steam-grilling equipment 2 during cooking can be quickly condensed and then discharged to the outside, avoiding burns to users when the hot steam is discharged, and improving the safety of using the steam-grilling equipment 2.
