Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a water-cooled pressure cooking appliance. Background Technology

[0002] Traditional cooking appliances release pressure by venting air after pressure cooking. This method is not only slow, affecting the user's ability to open the lid, but also produces considerable noise, resulting in a poor user experience. In recent years, some pressure cooking appliances have been equipped with a water tank. After pressure cooking, water from the tank is supplied to the inside of the lid, cooling the inner metal lid and achieving rapid pressure release.

[0003] Some pressure cooking appliances that use water cooling to reduce pressure have a water tank on the lid. During the water cooling and pressure reduction process, the water in the tank flows to the surface of the inner metal lid, where it comes into direct contact with the lid and exchanges heat, resulting in high cooling efficiency. The inner metal lid usually has a recessed cooling water groove to hold the water flowing out of the tank, preventing the cooling water from flowing freely on the surface of the lid.

[0004] However, due to the high temperature of the inner metal cover, some of the water flowing into it will vaporize, forming steam. In the initial stage of water cooling and pressure reduction, a significant amount of steam will be generated and ejected upwards as soon as the water flows into the inner metal cover. Since the control button for opening the water tank outlet or other operating components is located directly above or close to the cooling water tank within the inner metal cover, users' hands are likely to come into contact with the gushing hot steam when operating these components, posing a risk of burns.

[0005] Furthermore, as water cooling and pressure reduction proceed, more and more cooling water flows into and accumulates in the cooling water tank of the inner lid. This reduces the contact effect between the water and the metal inner lid, resulting in insufficient heat exchange and a significantly slower vaporization rate. Consequently, the heat absorption efficiency is low, and the cooling and pressure reduction effect is poor. Moreover, the accumulated water will be heated by the inner lid, further reducing the cooling rate. When too much water accumulates on the surface of the inner lid, it will overflow into the inside of the lid, affecting the electrical components inside. It also easily contaminates the inside of the lid, making it difficult for users to clean. Over time, dirt will accumulate inside the lid, emitting an odor and affecting the user experience. Utility Model Content

[0006] This utility model provides a water-cooled pressure cooking appliance to solve the problems that the operating parts for controlling the opening of the water tank are located above the inner cover water tank, which causes the water in the water tank to vaporize into high-temperature steam during the water cooling process, which may easily burn the user's hands upon contact, and the water in the water tank is prone to accumulation, resulting in a decrease in water cooling efficiency.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A water-cooled pressure cooking appliance includes a pot body and a pot lid. The pot lid includes a lid body and an inner lid located below the lid body. The inner lid and the pot body cooperate to form a cooking cavity. The upper surface of the inner lid is recessed with a cooling groove. A flow guiding structure for guiding the dispersion and flow of coolant is provided in the cooling groove. The pot lid also includes a water tank assembly disposed on the lid body and located above the cooling groove. The water tank assembly includes a tank body and a water outlet switch. The lid body and / or the tank body has an air vent corresponding to the cooling groove. The lid body is also provided with a water outlet operating component. The projection of the water outlet operating component toward the inner lid is located outside the cooling groove. The water outlet operating component is used to control the movement of the water outlet switch so that the coolant in the tank body drips into the cooling groove.

[0009] In this invention, the inner cover has a cooling groove located below the tank body to collect the coolant flowing out of the water tank. The tank body or cover has a vent above the cooling groove to allow steam generated within the cooling groove to escape. A water outlet actuator drives the water outlet switch to open the tank body, allowing the coolant inside to flow into the cooling groove. The water outlet actuator is offset vertically from the cooling groove, thus distancing it from the vent. Because the user's operating position is separate from the vent position, the impact of the high-temperature steam from the vent on the user's operation is greatly reduced, lowering the risk of burns from steam while operating the water outlet actuator and improving the user experience.

[0010] In addition, a flow-guiding structure is installed within the cooling groove. This structure guides the coolant entering the groove to flow in a dispersed manner, resulting in a more dispersed distribution of coolant within the groove and reducing the probability of coolant buildup. This ensures sufficient contact area between the coolant and the inner cover, improving heat exchange efficiency. Furthermore, it facilitates rapid coolant evaporation, further reducing coolant buildup within the cooling groove, improving the cleanliness of the inner cover, and reducing the cleaning burden on the user.

[0011] Furthermore, by controlling the flow rate and volume of the coolant as it flows out of the housing, the coolant enters the cooling groove by dripping. The volume of coolant dripping into the cooling groove is small, allowing for more thorough contact with the inner cover. This enables the coolant to quickly vaporize and form water vapor under the high temperature of the inner cover, further reducing the probability of coolant accumulating on the surface of the inner cover.

[0012] The cover is equipped with a handle, and the water outlet operation component is located on the handle.

[0013] In this design, users can operate the lid using the handle on the lid body, such as unlocking and locking the lid to the pot body, or lifting the lid off the pot body. Integrating the water dispensing mechanism into the handle not only centralizes the operation of the functional components on the lid, resulting in a simpler appearance, but also allows users to more intuitively locate and use the relevant operating mechanisms, thus facilitating user operation. Furthermore, it integrates the handle function, thereby saving costs.

[0014] The lid also includes a pressure relief valve and an exhaust pipe. The pressure relief valve is located at the top of the exhaust pipe to block the exhaust pipe. The lid is equipped with an exhaust control device, which is used to control the movement of the pressure relief valve to open the exhaust pipe. The exhaust control device is located on the handle.

[0015] In this design, the pressure relief valve is used to release pressure inside the pot after pressure cooking. The pressure relief valve is driven by an exhaust valve, which opens the exhaust pipe to release air, providing a manual venting function. The exhaust valve is located on the handle, integrating both the water outlet and exhaust valves. This further integrates the handle's functions, saving significant space on the lid surface, simplifying the lid's layout, and centralizing the control mechanisms for user convenience.

[0016] The cover is provided with a driving component, which includes a sensing part, a triggering part, and a connecting part located between the sensing part and the triggering part. The connecting part is rotatably connected to the cover. The sensing part is located below the water outlet operating component, and the triggering part is located below the water outlet switch. The water outlet operating component drives the water outlet switch through the driving component.

[0017] In this design, the water outlet control component does not directly contact the water outlet switch. Instead, it drives the switch via a driving mechanism, allowing for more flexible placement of the component. This helps to increase the distance between the control component and the steam outlet, further reducing the impact of steam ejection on user operation. The driving mechanism is rotatably connected to the lid, functioning as a lever mechanism. When the user presses the control component, the pressure sensor swings downwards, while the trigger at the other end swings upwards to lift the water outlet switch, opening the water outlet. This two-end swinging transmission not only allows for effortless operation through a designed lever arm length but also minimizes the space occupied by the driving component, thus saving internal space in the lid and enabling a thinner, smaller lid design.

[0018] The water outlet switch includes a push rod and a sealing part. The bottom wall of the housing has a water outlet. The sealing part abuts against the edge of the water outlet to seal the water outlet. The push rod can move upward to disengage the sealing part from the edge of the water outlet. The lower end of the sealing part has a protruding transmission protrusion.

[0019] In this design, the sealing part abuts against the edge of the outlet from top to bottom to seal. Since the sealing part is located inside the housing and is difficult to drive, a downward-protruding transmission protrusion is provided at its lower end. The transmission protrusion extends outside the housing and is used to cooperate with the driving component or the water outlet operating component, thereby ensuring that the water outlet operating component can effectively apply a stable pushing force to the push rod, causing the push rod to drive the sealing part to move upward, thereby disengaging from the edge of the outlet and opening the outlet.

[0020] The housing includes a water storage section and an exhaust section. The water storage section has a water storage chamber, and the exhaust port is located in the exhaust section. The housing is detachably installed on the cover.

[0021] In this design, the air outlet is located within the housing, which is detachably mounted to the cover. This allows the water tank assembly to form a complete water-cooling unit, which can be installed entirely onto or removed from the cover. Users can remove the housing to add coolant, making the replenishment process more convenient and quick. Furthermore, when the water tank assembly is removed for cleaning, the interior of the housing and the air outlet can be cleaned simultaneously, making cleaning more efficient.

[0022] The water tank assembly also includes a tank cover that can move relative to the tank body to open or close the water storage chamber.

[0023] In this design, the cover can move relative to the tank body to fully open the water storage chamber, allowing users to replenish coolant into the water storage chamber in multiple ways. They can either remove the tank body from the cover, replenish the coolant, and then reinstall the cover, or they can open the cover directly without removing the tank body to add coolant, thus enabling quick replenishment of coolant even during pressure reduction.

[0024] The flow guiding structure includes multiple flow guiding protrusions set on the bottom wall of the cooling groove, with spaced intervals between them, and a water collection groove formed between two adjacent flow guiding protrusions.

[0025] In this design, multiple guide protrusions are spaced apart on the bottom wall of the cooling groove, forming a water collection trough between adjacent protrusions, thus improving the dispersion of coolant within the cooling groove. For example, when coolant drips into a water collection trough, due to its shallow depth, once the trough is full, the coolant overflows into other water collection troughs on either side, preventing a large accumulation of coolant in one area. Similarly, when coolant drips onto a guide protrusion, it is guided by the protrusion and splits into two streams, flowing into the water collection troughs on either side.

[0026] The flow guiding structure includes a flow guiding protrusion set on the bottom wall of the cooling groove. The flow guiding protrusion is set vertically and vertically corresponding to the water outlet of the box. The surface of the flow guiding protrusion has a flow guiding slope that can guide the liquid to flow in all directions.

[0027] In this design, the outlet and the guide protrusion are aligned vertically. When the coolant flows out of the outlet, it drips onto the guide protrusion and then, guided by the guide slope on the surface of the guide protrusion, it disperses and flows in all directions, thus making the coolant distribution more dispersed, avoiding the accumulation of a large amount of coolant in a certain area, ensuring the contact area between the coolant and the inner cover, and ensuring heat exchange efficiency.

[0028] The projection of the cooling groove toward the cover covers the water tank assembly.

[0029] In this design, the projected area of ​​the cooling groove is larger than that of the water tank, so that the cooling groove fully covers the water tank assembly. On the one hand, this ensures that the coolant inside the tank can accurately drip into the cooling groove, avoiding contamination of other areas of the inner cover. On the other hand, it can increase the area of ​​the cooling groove to a certain extent, thereby increasing the heat exchange area with the coolant and improving the cooling efficiency.

[0048] like Figure 1 , Figure 2 As shown, a water-cooled pressure cooking appliance includes a pot body and a pot lid. The pot lid includes a lid body 1 and an inner lid 3 located below the lid body 1. The inner lid 3 cooperates with the pot body to form a cooking cavity. The upper surface of the inner lid 3 is recessed with a cooling groove 31. A guide structure 32 for guiding the dispersion and flow of coolant is provided in the cooling groove 31. The pot lid also includes a water tank assembly 2 disposed on the lid body 1 and located above the cooling groove 31. The water tank assembly 2 includes a tank body 22 and a water outlet switch 23. The lid body 1 and / or the tank body 22 are provided with an air outlet 21 corresponding to the cooling groove 31. The lid body 1 is also provided with a water outlet operating component 12. The projection of the water outlet operating component 12 toward the inner lid 3 is located outside the cooling groove 31. The water outlet operating component 12 is used to control the movement of the water outlet switch 23 so that the coolant in the tank body 22 drips into the cooling groove 31.

[0049] In one specific embodiment, the coolant is water. Users can directly add municipal tap water to the tank 22 as coolant to save on user costs. Of course, the coolant can also be other liquid media, which is not limited here.

[0050] In this invention, the inner cover 3 is provided with a cooling groove 31 located below the housing 22 to receive the coolant flowing out of the water tank. The housing 22 or the cover 1 has a vent 21 above the cooling groove 31 to allow the steam generated within the cooling groove 31 to escape. The water outlet operating component 12 drives the water outlet switch 23 to open the housing 22, allowing the coolant inside the housing 22 to flow into the cooling groove 31. The water outlet operating component 12 is vertically offset from the cooling groove 31, thus distancing it from the vent 21. Because the user's operating position and the vent position are separated and located in different areas, the impact of the high-temperature steam flowing from the vent 21 on the user's operation is greatly reduced, lowering the risk of burns to the user's hands from the steam flowing from the vent 21 when operating the water outlet operating component 12, and improving the user experience.

[0051] Furthermore, a flow guiding structure 32 is provided within the cooling groove 31. This structure guides the coolant entering the cooling groove 31 to flow in a dispersed manner, resulting in a more dispersed distribution of coolant within the groove 31 and reducing the probability of coolant accumulation. This ensures sufficient contact area between the coolant and the inner cover 3, improving heat exchange efficiency. It also facilitates rapid coolant evaporation, further reducing coolant accumulation within the cooling groove 31, improving the cleanliness of the inner cover 3, and reducing the user's cleaning burden.

[0052] Furthermore, by controlling the flow rate and volume of the coolant as it flows out of the housing 22, the coolant enters the cooling groove 31 by dripping. The volume of coolant dripping into the cooling groove 31 is small, resulting in more thorough contact with the inner cover 3. This allows the coolant to quickly vaporize and form water vapor under the high temperature of the inner cover 3, further reducing the probability of coolant accumulating on the surface of the inner cover 3.

[0053] It should be noted that the water outlet control component 12 refers to the component directly operated by the user. In one specific embodiment, such as... Figure 1 As shown, the water outlet operating component 12 is a button structure, which the user presses. Of course, the water outlet operating component 12 can also have other structures or movement methods, which are not limited here. The water outlet operating component 12 can directly drive the water outlet switch 23 to move, or it can indirectly drive the water outlet switch 23 through various transmission mechanisms.

[0054] Furthermore, it should be noted that although the pressure cooking appliance of this utility model is equipped with a water tank assembly 2, which can reduce pressure by water cooling, the pressure cooking appliance of this utility model can also be equipped with an exhaust pressure relief assembly, so as to assist in pressure reduction by exhausting air. By combining water cooling pressure reduction and exhaust pressure relief, more efficient pressure relief can be achieved.

[0055] As a preferred embodiment of this utility model, such as Figure 1 , Figure 2 As shown, the cover 1 is provided with a handle 11, and the water outlet operation component 12 is provided on the handle 11.

[0056] Users can operate the lid using the handle 11 on the lid body 1, such as unlocking and locking the lid to the pot body, or lifting the lid off the pot body. Integrating the water dispensing mechanism 12 into the handle 11 not only centralizes the operation of the functional components on the lid, making the lid's surface appearance simpler, but also allows users to more intuitively locate and use the relevant operating structures, thus facilitating user operation. Furthermore, it integrates the functions of the handle 11, thereby saving costs.

[0057] Specifically, such as Figure 1 , Figure 2As shown, the cooling groove 31 is eccentrically positioned on the inner cover 3, and the water tank assembly 2 is positioned vertically and vertically corresponding to the cooling groove 31, thus also eccentrically positioned on the cover 1, with the handle 11 located at the center of the inner cover 3. Alternatively, the cooling groove 31 can be positioned at the center of the inner cover 3, with the water tank assembly 2 positioned accordingly. In this case, the handle 11 can be eccentrically positioned on the cover 1.

[0058] Preferably, such as Figure 5 As shown, the cooling groove 31 extends circumferentially along the inner cover 3 to increase the area of ​​the cooling groove 31, thereby increasing the heat exchange area and improving the cooling efficiency.

[0059] Preferably, such as Figure 1 As shown, the pot lid also includes a pressure relief valve 4 and an exhaust pipe. The pressure relief valve 4 is located at the top of the exhaust pipe to block the exhaust pipe. The lid body 1 is provided with an exhaust operation component 13, which is used to control the movement of the pressure relief valve 4 to open the exhaust pipe. The exhaust operation component 13 is located on the handle 11.

[0060] The pressure relief valve 4 is used to release pressure inside the pot after pressure cooking. The venting actuator 13 drives the pressure relief valve 4 to open the vent pipe for manual venting. The venting actuator 13 is located on the handle 11, integrating both the water outlet actuator 12 and the venting actuator 13 onto the handle 11. This further integrates the functions of the handle 11, saving significant space on the pot lid surface, simplifying the lid's surface structure, and concentrating the operating mechanisms for user convenience.

[0061] Specifically, in one embodiment, such as Figure 1 As shown, the water outlet control component 12 and the venting control component 13 are both located on the upper surface of the handle 11. Both are semi-circular structures that together form a complete circular pattern. Of course, they can also be other shapes to create other patterns and enhance the aesthetic appeal. Furthermore, the water outlet control component 12 and / or the venting control component 13 can also be located on the side of the handle 11 or in other positions; this is not limited here.

[0062] Specifically, such as Figure 2 As shown, the cover 1 is provided with a transmission component 15, which is rotatably connected to the cover 1 to form a lever structure. The exhaust operation component 13 is a button structure. When the user presses the exhaust operation component 13, it presses down one end of the transmission component 15, causing the other end of the transmission component 15 to rise, thereby lifting the pressure relief valve 4 and opening the exhaust pipe.

[0063] Preferably, such as Figure 2As shown, the cover 1 is provided with a driving member 14. The driving member 14 includes a sensing part 141, a trigger part 142, and a connecting part 143 located between the sensing part 141 and the trigger part 142. The connecting part 143 is rotatably connected to the cover 1. The sensing part 141 is located below the water outlet operation member 12, and the trigger part 142 is located below the water outlet switch 23. The water outlet operation member 12 drives the water outlet switch 23 through the driving member 14.

[0064] The water outlet operating component 12 does not directly contact the water outlet switch 23. Instead, it drives the water outlet switch 23 through the transmission of the driving component 14. This allows for more flexible placement of the water outlet operating component 12, which helps to further increase the distance between the water outlet operating component 12 and the steam outlet 21, thereby reducing the impact of steam ejection from the steam outlet 21 on user operation. The driving component 14 is rotatably connected to the lid 1, making it a lever mechanism. When the user presses the water outlet operating component 12, the pressure sensing part 141 of the water outlet operating component 12 swings downward. At the same time, the trigger part 142 at the other end swings upward to lift the water outlet switch 23, opening the water outlet 224 of the housing 22. The transmission via the swinging motion of the two ends of the driving component 14 not only allows for effortless operation through the design of the lever arm length, but also reduces the space occupied by the driving component 14 during movement. This helps save space inside the lid, enabling a thinner and smaller lid design.

[0065] Specifically, such as Figure 1 , Figure 2 As shown, the housing 22 and the exhaust pipe are located on both sides of the handle 11. The sensing part 141 of the drive member 14 and one end of the transmission member 15 are both located below the handle 11. The sensing part 141 is vertically aligned with the water outlet operation member 12, and one end of the transmission member 15 is vertically aligned with the exhaust operation member 13.

[0066] In other embodiments, the drive member 14 can also trigger the water outlet switch 23 by moving in other ways. For example, the drive member 14 is slidably installed on the cover 1, and both ends of the drive member 14 are provided with mating inclined surfaces. When the water outlet operating member 12 is pressed down, the drive member 14 is driven to move horizontally by the mating inclined surfaces. The drive member 14 forms an upward pushing force on the water outlet switch 23 through the mating inclined surfaces at the other end, thus lifting the water outlet switch 23.

[0067] Alternatively, the water outlet switch 23 can also be configured to move horizontally, and the water outlet switch 23 can be pushed horizontally by the drive component 14 to open the water outlet 224 of the housing 22. This is not limited here.

[0068] In a preferred embodiment, such as Figure 3 , Figure 4As shown, the water outlet switch 23 includes a push rod 231 and a sealing part 232. The bottom wall of the housing 22 has a water outlet 224. The sealing part 232 abuts against the edge of the water outlet 224 to seal the water outlet 224. The push rod 231 can move upward to disengage the sealing part 232 from the edge of the water outlet 224. The lower end of the sealing part 232 has a protruding transmission protrusion 233.

[0069] The sealing part 232 abuts against the edge of the outlet 224 from top to bottom to seal. Since the sealing part 232 is located inside the housing 22 and is difficult to be driven, a downward protruding transmission protrusion 233 is provided at its lower end. The transmission protrusion 233 extends out of the housing 22 and is used to cooperate with the driving component 14 or the water outlet operating component 12, thereby ensuring that the water outlet operating component 12 can effectively apply a stable pushing force to the push rod 231, so that the push rod 231 drives the sealing part 232 to move upward, thereby disengaging from the edge of the outlet 224 and opening the outlet 224.

[0070] Preferably, such as Figure 4 As shown, the lower surface of the transmission protrusion 233 is provided with a contact plane, and one end of the drive member 14 or the water outlet operation member 12 is provided with a transmission plane, so that the two can make contact through the plane and transmit the force, improve the contact stability, and make the push rod 231 move reliably.

[0071] Preferably, such as Figure 4 As shown, a sealing bevel is provided on the outer periphery of the sealing part 232 and / or the edge of the outlet 224 to make the contact between the sealing part 232 and the edge of the outlet 224 tighter and improve the sealing effect.

[0072] In one embodiment, such as Figure 4 As shown, an elastic portion 234 is sleeved on the outer periphery of the push rod 231, which applies a downward pushing force to the push rod 231 and the sealing portion 232, thereby pushing the push rod 231 and the sealing portion 232 to move down and reset, so that the sealing portion 232 resumes contact with the edge of the outlet 224. Of course, in another embodiment, the elastic portion 234 may be omitted, allowing the push rod 231 and the sealing portion 232 to fall and reset under their own gravity.

[0073] As a preferred embodiment of this utility model, such as Figure 3 As shown, the housing 22 includes a water storage section 221 and an exhaust section 222. The water storage section 221 has a water storage chamber 223, and the exhaust port 21 is opened in the exhaust section 222. The housing 22 is detachably installed on the cover 1.

[0074] The air outlet 21 is located on the housing 22, and the housing 22 is detachably installed on the cover 1, allowing the water tank assembly 2 to form a complete water-cooling unit, which can be installed entirely on or removed from the cover 1. Users can remove the housing 22 to add coolant, making the replenishment process more convenient and faster. Furthermore, when the water tank assembly 2 is removed for cleaning, the interior of the housing 22 and the air outlet 21 can be cleaned simultaneously, making cleaning more convenient.

[0075] Of course, in other embodiments, the air outlet 21 may also be provided on the cover 1, which is not limited here.

[0076] Preferably, the exhaust section 222 and the water outlet are staggered to avoid the high-temperature steam ejected from the exhaust port from contacting the coolant in the water storage chamber 223, which would cause the coolant temperature to rise. Specifically, such as Figure 3 As shown, the venting section 222 is located on both sides or around the water storage section 221. That is, the outer side of the water outlet section is provided with outward protruding ribs to form the venting section 222.

[0077] Furthermore, such as Figure 3 , Figure 4 As shown, the water tank assembly 2 also includes a tank cover 24, which is movable relative to the tank body 22 to open or close the water storage chamber 223.

[0078] The cover 24 can move relative to the housing 22 to fully open the water storage chamber 223, allowing users to add coolant to the water storage chamber 223 in various ways. They can either remove the housing 22 from the cover 1, add coolant, and then reinstall the cover 1, or they can open the cover 24 directly without removing the housing 22 to add coolant, thus allowing for quick coolant replenishment during pressure reduction.

[0079] In one embodiment, such as Figure 3 , Figure 4 As shown, one end of the lid 24 is rotatably connected to the body 22, allowing the lid 24 to be flipped relative to the body 22 to open and close. In other embodiments, the lid 24 can also be opened and closed by sliding the water storage chamber 223. Alternatively, the lid 24 can be designed as a detachable structure from the body 22 to fully open the water storage chamber 223; this is not a limitation.

[0080] This utility model does not limit the specific structure of the flow guiding structure 32 in the cooling groove 31, but it includes, but is not limited to, the situations listed in the following embodiments:

[0081] Implementation Method 1: In this implementation method, as follows Figure 5 , Figure 6 , Figure 7As shown, the flow guiding structure 32 includes flow guiding protrusions 321 disposed on the bottom wall of the cooling groove 31. There are multiple flow guiding protrusions 321 and they are spaced apart. A water collection groove 322 is formed between two adjacent flow guiding protrusions 321.

[0082] like Figure 7 As shown, multiple guide protrusions 321 are spaced apart on the bottom wall of the cooling groove 31, thereby forming a water collection groove 322 between two adjacent guide protrusions 321, which improves the dispersion effect of the coolant inside the cooling groove 31.

[0083] For example, when the outlet 224 of the housing 22 corresponds vertically to a certain water collection tank 322, the coolant drips into the water collection tank 322. Since the water collection tank 322 is shallow, when the water collection tank 322 is full of coolant, the coolant will overflow into other water collection tanks 322 on the adjacent sides, thereby avoiding the situation where a large amount of coolant accumulates in a certain area.

[0084] For example, when the outlet 224 of the housing 22 corresponds vertically to a certain guide protrusion 321, the coolant drips onto the guide protrusion 321 and is divided into two streams under the guidance of the guide protrusion 321, flowing into the water collection tanks 322 on both sides respectively.

[0085] Preferably, the surface of the guide protrusion 321 is provided with a guide transition surface (which can be an inclined surface, an arc surface, or other curved surface structure) that extends obliquely into the water collection tanks 322 on both sides.

[0086] Implementation Method 2: In this embodiment, the flow guiding structure 32 includes a flow guiding protrusion 321 disposed on the bottom wall of the cooling groove 31. The flow guiding protrusion 321 is disposed vertically and vertically corresponding to the water outlet 224 of the box body 22. The surface of the flow guiding protrusion 321 has a flow guiding slope that can guide the liquid to flow in all directions.

[0087] The outlet 224 corresponds vertically to the guide protrusion 321. When the coolant flows out of the outlet 224, it drips onto the guide protrusion 321. Then, guided by the guide slope on the surface of the guide protrusion 321, it disperses and flows in all directions, thereby making the distribution of coolant more dispersed, avoiding the accumulation of a large amount of coolant in a certain area, ensuring the contact area between the coolant and the inner cover 3, ensuring heat exchange efficiency, and preventing a large amount of coolant from accumulating in the cooling groove 31 and overflowing into other areas of the inner cover 3.

[0088] Preferably, such as Figure 2 As shown, the projection of the cooling groove 31 toward the cover 1 covers the water tank assembly 2.

[0089] The projected area of ​​the cooling groove 31 is larger than the area of ​​the water tank, so that the cooling groove 31 fully covers the water tank assembly 2. On the one hand, this ensures that the coolant in the tank body 22 can accurately drip into the cooling groove 31, avoiding contamination of other areas of the inner cover 3. On the other hand, it can increase the area of ​​the cooling groove 31 to a certain extent, thereby increasing the heat exchange area with the coolant and improving the cooling efficiency.
