Detailed Implementation

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0054] The water-cooling system provided in this application embodiment can be applied to equipment that requires exhaust and cooling, such as steam ovens, ovens, steam ovens, or integrated stoves with integrated steam ovens. To better understand the technical solution of this application, the following will use a steam oven as an example for explanation.

[0055] Please see Figure 1 , Figure 1 This is a schematic diagram of a water-cooling system provided in an embodiment of this application. The water-cooling system includes a water tank 1, a refrigeration device 2, an outlet pipe 3, a return pipe 4, and a double-layer pipe 5. The refrigeration device 2 is located on the water tank 1 and is used to cool the water in the water tank 1. The water tank 1 includes an outlet hole 101 and a return hole 102. The outer wall of the double-layer pipe 5 is provided with a first through hole 501 and a second through hole 502. The height of the first through hole 501 from the bottom of the equipment is greater than the height of the second through hole 502 from the bottom of the equipment. One end of the outlet pipe 3 is connected to the outlet hole 101, and the other end of the outlet pipe 3 is connected to the second through hole 502. One end of the return pipe 4 is connected to the return hole 102, and the other end of the return pipe 4 is connected to the first through hole 501. The outlet pipe 3 and the return pipe 4 are both connected to the outer channel of the double-layer pipe 5. The inner channel of the double-layer pipe 5 is used to discharge steam from the equipment or to draw external gas into the equipment.

[0056] When the inner channel of the double-layer pipe 5 is used to draw external gas into the equipment, the outer channel of the double-layer pipe 5 is filled with cooling water, which can cool the external gas in the inner channel of the double-layer pipe 5. This ensures that the gas entering the inner tank 8 is not affected by the external ambient temperature, thus guaranteeing the effect of less steam when the door is opened after the steaming function is completed and the stability of the function.

[0057] Furthermore, when the inner channel of the double-layer pipe 5 is used to discharge steam from the equipment, the outer channel of the double-layer pipe 5 is filled with cooling water, which can condense the steam in the inner channel of the double-layer pipe 5, reduce the amount of steam discharged, and extend the duration of the equipment's steam function.

[0058] Please see Figure 2 , Figure 2 This is a layout diagram of a water-cooling system provided in an embodiment of this application. The device is equipped with an exhaust pipe 9, one end of which is connected to a position on the inner liner 8. The air inlet of the aforementioned double-layer pipe 5 is connected to another position on the inner liner 8. When the hot air blower 10 is rotating, a pressure difference exists between these two positions, allowing the exhaust pipe 9 to exhaust air and the double-layer pipe 5 to intake air. When the hot air blower 10 is not rotating, such as when cooking is finished, both the exhaust pipe 9 and the double-layer pipe 5 are used for exhaust, thus quickly removing the high-temperature steam from the inner liner 8. Therefore, the water-cooling system can improve the dehumidification performance of the baking function. After the steaming function ends, the high-speed hot air blower 10 rotates for a certain period before opening the door to achieve the function of less steam when opening the door. Optionally, to better understand the technical solution and beneficial effects of this application, the structure of the inner liner 8 will be briefly described first. The inner liner 8 can be a cube or a cuboid structure. Please continue reading... Figure 2The inner liner 8 specifically includes a first plate, a second plate, a third plate, a fourth plate, and a back plate. The first, second, third, and fourth plates are connected end-to-end to form a closed enclosure. The back plate has an opening on one side of this closed enclosure, thus forming a groove structure. Specifically, the back plate has multiple vents and a hot air blower 10. Steam in the inner liner 8 can flow into the exhaust pipe 9 through the vents or be discharged through the inner channel of the double-layer pipe 5. Since the outer channel of the double-layer pipe 5 is filled with cooling water, the high-temperature steam in the inner channel can be condensed, reducing the amount of steam discharged and extending the duration of the steaming function. Specifically, one end of the exhaust pipe 9 is located on the outside of the back plate, close to the hot air blower 10, while the other end of the exhaust pipe 9 is exposed to the air and close to the second plate (i.e., the top plate of the inner liner 8). The air inlet of the double-layer pipe 5 is located at the edge of the back plate, close to the first plate, and the exhaust outlet of the double-layer pipe 5 is exposed to the air and close to the second plate. In fact, the ports of exhaust pipe 9 and double-layer pipe 5 are not limited to the above-mentioned configuration, as long as the pressure difference at the ports is large after the hot air blower 10 is turned on. For example, the hot air blower 10 can be set to a high speed, at least greater than 1150 r / pm, such as a high speed of 2300 r / pm. This will cause the air inside the chamber to rise due to heat and be drawn into the hot air blower 10 to do work, increasing the pressure. Since the flow resistance of the exhaust pipe at the back, i.e., exhaust pipe 9, is small, steam is discharged upwards from exhaust pipe 9 first. The flow resistance of the side exhaust pipe, i.e., double-layer pipe 5, is larger, forming a backflow negative pressure zone. Cold air from outside is continuously drawn in, thus forming a dual-path convection circulation. This ensures that after cooking, the "smoke" does not rush out when the door is opened. During the cooking process, the two exhaust paths, together with the dual-speed hot air blower, enhance the roasting performance of vegetables and fruits.

[0059] In one possible implementation, please refer to [link / reference needed]. Figure 2 The cooling system also includes a water pump 6, and the outlet pipe 3 includes a first pipe 301 and a second pipe 302; the inlet of the first pipe 301 is connected to the outlet hole 101, and the outlet of the first pipe 301 is connected to the inlet of the water pump 6; the inlet of the second pipe 302 is connected to the inlet of the water pump 6, and the outlet of the second pipe 302 is connected to the second through hole 502. The water pump 6 can supply cooling water at a lower level to the double-layer pipe 5.

[0060] In one possible implementation, please refer to Figure 3 The refrigeration unit 2 is located on the outer wall of the water tank 1. Optionally, the outer wall of the water tank 1 is also provided with a fixing structure 601 for fixing the water pump 6. This fixing structure 601 and the refrigeration unit 2 are located on the same side wall of the water tank 1. The water tank 1 also includes a cover plate 106 (e.g., Figure 4 As shown, the cover plate 106 is provided with a water inlet for adding water to the water tank 1 through the water inlet.

[0061] In one possible implementation, please refer to Figure 5 The outlet hole 101 and the return hole 102 are located on the side of the water tank 1 near the double-layer pipe 5; the outlet hole 101 is near the bottom of the water tank 1, and the return hole 102 is near the top of the water tank 1. Because there is a certain height difference between the outlet hole 101 and the return hole 102, and the return hole 102 is positioned higher, the height difference between the return hole 102 and the outlet hole 101 can be used to cool the return water, thus accelerating the water cooling efficiency. Optionally, the outlet hole 101 and the return hole 102 can also be located in other positions as needed, such as on different sides of the water tank 1, thereby increasing the path length of the return water flowing to the outlet hole 101 to further improve the water cooling effect.

[0062] In one possible implementation, please refer to [link / reference needed]. Figure 5 The water tank 1 includes an isolation element 103. The isolation element 103 is disposed within the cavity of the water tank 1 and divides the cavity of the water tank 1 into a first water cavity 104 and a second water cavity 105. The first water cavity 104 is used to supply water to the steam generating device of the equipment. The refrigeration device 2 is located near the second water cavity 105 and is used to cool the water in the second water cavity 105. The water outlet 101 and the water return 102 are both connected to the second water cavity 105. The second water cavity 105, the water outlet pipe 3, the water return pipe 4, and the double-layer pipe 5 form a water-cooled closed loop. The refrigeration device 2 can specifically be a semiconductor refrigeration device 2, which can be a flat plate structure. By setting it on the side wall of the second water cavity 105, the second water cavity 105 can be cooled. In order to improve the refrigeration efficiency, the isolation element 103 can be a heat-insulating and cold-insulating material, so that the room temperature water in the first water cavity 104 will not affect the second water cavity 105, and the cooling water in the second water cavity 105 can also maintain a lower temperature. Optionally, the water outlet 101 and the water return 102 are located on the same side wall of the second water cavity 105, but they can also be located on different side walls of the second water cavity 105 as needed.

[0063] In one possible implementation, please refer to Figure 6 , Figure 6This is a schematic diagram of a water outlet provided in an embodiment of this application. The water outlet 101 includes a first hole structure 1011 and a second hole structure 1012 connected together; the first hole structure 1011 is located inside the side wall of the water tank 1; the second hole structure 1012 includes a first end 1013 and a second end 1014 opposite to each other; the first end 1013 extends out of the side wall of the water tank 1 and is located inside the water tank 1, specifically inside the second water cavity 105; the second end 1014 is connected to the first hole structure 1011. Optionally, in order to improve the sealing effect, the water outlet 101 also includes a third hole structure 1016, which is connected to the first hole structure 1011, and the free end of the third hole structure 1016 is exposed outside the water tank 1. A sealing element 703 is provided inside the third hole structure 1016. The sealing element 703 is an annular structure, and the water outlet pipe 3 can pass through the sealing element 703 and the first hole structure 1011 to reach the second hole structure 1012. Optionally, the seal 703 can be a wedge-shaped structure.

[0064] In one possible implementation, please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of a sealing assembly provided in an embodiment of this application; Figure 8This is a schematic diagram of another water outlet structure provided in an embodiment of this application. A hollow area 1015 is provided on the first hole structure 1011; a sealing component 7 is provided inside the water outlet 101; the sealing component 7 includes a spring-loaded member 701 and a blocking member 702; one end of the spring-loaded member 701 abuts against the first end 1013 of the second hole structure 1012, and the other end of the spring-loaded member 701 is provided with the blocking member 702; when the spring-loaded member 701 is in the first state, the blocking member 702 abuts against the second end 1014 of the second hole structure 1012; after the water inlet end 303 of the water outlet pipe 3 is inserted into the water outlet 101, the spring-loaded member 701 is in the second state, and the blocking member 702 moves away from the second end 1014; the water inlet end 303 is provided with multiple water inlets, which are used to communicate with the hollow area 1015. Optionally, the hollow area 1015 can surround multiple through holes arranged circumferentially around the first hole structure 1011 to form a grid structure. The inlet end 303 can be multiple concave notches arranged circumferentially along the pipe opening. When the inlet end 303 penetrates into the first hole structure 1011, it will push the blocking member 702 towards the first end 1013 until the multiple inlets of the inlet end 303 contact the hollow area 1015. By rotating the outlet pipe 3, the multiple inlets can be connected to the hollow area 1015, so that the cooling water can flow into the outlet pipe 3 through the hollow area 1015 and the inlets in sequence. When it is necessary to add water to the water tank 1, the outlet pipe 3 can be pulled out. At this time, the spring member 701 is subjected to the restoring force and moves towards the second end 1014, thereby driving the blocking member 702 connected to the spring member 701 to move towards the second end 1014 until the blocking member 702 abuts against the second end 1014. Since the blocking member 702 covers the hole of the first hole structure 1011, the water in the water tank 1 after it is filled with water cannot flow out. Optionally, the aforementioned hollow area 1015 can be located in the area near the second end 1014 of the first hole structure 1011, or in the area near the first end 1013 of the first hole structure 1011, or in the middle of the first hole structure 1011. No limitation is imposed here.
