Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a cooking appliance. Background Art

[0002] After the pressure cooking of traditional cooking appliances is completed, pressure relief is carried out by exhausting gas. This pressure relief method not only has a slow pressure relief speed, affecting the user to open the lid, but also generates relatively large noise during the exhaust process, resulting in a poor user experience. In recent years, some pressure cooking appliances are equipped with a water tank. After the pressure cooking is completed, the water in the water tank is pumped into the inner lid of the pot cover to cool the metal inner lid of the pot cover by water cooling to achieve rapid pressure relief.

[0003] For cooking appliances with the function of water-cooled pressure reduction, there are generally two types of water-cooled structures for the pot cover. One is to add a cooling component to the pot cover to construct an independent water-cooled chamber on the pot cover, and supply a water-cooling medium into the water-cooled chamber, and then cool the inner lid. In this solution, the water-cooling medium flows in the water-cooled chamber and does not directly contact the inner lid, resulting in a long heat transfer path between the water-cooling medium and the inner lid, low cooling efficiency of the inner lid, and slow pressure reduction speed.

[0004] Another method is that the water-cooling medium directly flows to the surface of the inner lid and directly contacts the inner lid to cool it. In this solution, the inner lid can directly contact the water flow medium for heat exchange, and the cooling efficiency is relatively high. However, part of the water-cooling medium flowing to the surface of the inner lid is vaporized by heat to form water vapor, part flows back into the water tank, and part remains on the surface of the inner lid. Thus, when the user opens the lid after the pressure reduction is completed, the flipping of the pot cover will cause the water-cooling medium remaining on the surface of the inner lid to flow to other areas inside the pot cover, which not only easily affects the electrical components inside the pot cover, but also easily contaminates the inside of the pot cover, and it is difficult for the user to clean. Over time, dirt will accumulate inside the pot cover and emit odors, affecting the use experience. Summary of the Utility Model

[0005] The utility model provides a cooking appliance to solve the problem that the water-cooling medium will flow arbitrarily inside the pot cover, affecting the cleanliness inside the pot cover and the service life of electrical components, on the basis of improving the cooling efficiency of the inner lid by water-cooled pressure reduction.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A cooking appliance includes a pot body and a pot lid. The pot lid includes a lid body and an inner lid. The inner lid cooperates with the pot body to form a cooking cavity. An opening is provided on the top surface of the lid body, and a cooling area corresponding to the opening is provided on the top surface of the inner lid. The lid body is provided with a sealing portion extending downward. The sealing portion surrounds the outer periphery of the cooling area and abuts and seals against the top surface of the inner lid. The cooking appliance further includes a water tank provided on the pot lid. At least a part of the water tank is exposed on the upper surface of the lid body. The water tank, the sealing portion and the cooling area cooperate to enclose a cooling cavity. The water tank has a water outlet facing the cooling area, so that the water in the water tank flows out from the water outlet to the cooling area.

[0008] The cooking appliance of the present utility model further has the following additional technical features:

[0009] The sealing portion is a rib extending downward from the rim of the opening, and the rib abuts against the top surface of the inner lid; alternatively, the sealing portion includes a sealing ring provided on the lid body and extending downward, and the sealing ring abuts against the top surface of the inner lid.

[0010] The cooling area is recessed downward to form a cooling sink. The cooling sink cooperates with the water tank to form a cooling cavity. The sealing portion surrounds the outer periphery of the cooling sink. The lid body is provided with an air outlet communicating with the cooling cavity.

[0011] An outlet switch is provided inside the water tank. The upper end of the outlet switch has an operating portion extending outside the water tank. The lower end of the outlet switch is provided with a seal. The outlet switch can move up and down to make the seal block or open the water outlet.

[0012] The water outlet is provided on the bottom wall of the water tank. The inner bottom wall of the water tank is provided with a diversion slope extending obliquely downward toward the water outlet.

[0013] The top of the water tank is provided with a water inlet. The side wall of the water tank extends obliquely, so that the width of the top of the water tank is greater than the width of the bottom of the water tank.

[0014] The top of the water tank is provided with a water inlet. The cooking appliance further includes an upper cover connected to the water tank. The upper cover can move relative to the water tank to open or close the water inlet.

[0015] The water tank is made of a transparent material. At least one water level mark is provided on the side wall of the water tank.

[0016] The water level mark includes a first water level line and a second water level line. The first water level line corresponds to the maximum amount of water required for pressure reduction when the cooking appliance is operating at the rated working pressure. The second water level line is located below the first water level line.

[0017] The pot lid further includes a cover plate detachably fixed to the opening. The cover plate and the cooling area cooperate to enclose a cooling cavity. The water tank is provided on the cover plate.

[0018] Due to the adoption of the above technical solutions, the beneficial effects obtained by the present utility model are:

[0019] 1. In this utility model, an opening is provided on the top surface of the cover body, so that a partial area of the inner cover is exposed to the outside through the opening. When the water tank is installed on the cover body, the water tank and the cooling area cooperate to form a cooling cavity, enabling the water in the water tank to directly flow to the cooling area and contact the inner cover, and directly exchange heat with the inner cover, ensuring the cooling efficiency of the inner cover. And when the water tank is not installed, the cooling area is exposed to the outside, and the user can directly wipe and clean the cooling area, reducing the cleaning difficulty and helping to keep the inside of the cooling cavity clean. At least a partial area of the water tank is exposed on the upper surface of the cover body, enabling the user to directly observe the water volume inside the water tank from the outside, as well as perform operations of adding water and / or discharging water to the water tank. This not only saves the internal space of the pot lid, avoids the built-in water tank in the pot lid resulting in a bloated structure and increased weight of the pot lid, but also facilitates the use of the user and improves the usage experience.

[0020] In addition, a sealing portion protruding downward is provided on the outer periphery of the opening of the cover body. The sealing portion abuts against and seals the inner cover, isolating the cooling cavity from the internal space of the pot lid, so that the cooling cavity is located outside the pot lid. When cooling the cooling area, the heat transfer performance of the inner cover itself can be used to cool other areas of the inner cover, but the water in the cooling cavity will not flow into other gaps inside the pot lid. Even if a small amount of unevaporated water accumulates in the cooling area, under the sealing action of the sealing portion, even if the pot lid is flipped, the water will not flow into the inside of the pot lid, resulting in difficulty in cleaning. At the same time, water vapor, flue gas, etc. inside the pot lid will not enter the cooling cavity, ensuring the cleanliness of the cooling cavity and reducing the cleaning pressure on the user.

[0021] 2. As a preferred implementation manner of this utility model, the cooling area is recessed downward to form a cooling sink. The cooling sink and the water tank cooperate to form a cooling cavity. The sealing portion surrounds the outer periphery of the cooling sink, and the cover body is provided with an air outlet communicating with the cooling cavity. The setting of the cooling sink makes at least a partial area of the cooling area recess downward relative to the top surface of the inner cover, thereby reducing the position height, enabling the cooling sink to collect the water flowing out of the water tank, and further reducing the probability of the water in the cooling cavity flowing into the inside of the pot lid. The air outlet is used for discharging the water vapor heated and vaporized in the cooling cavity, ensuring the stable air pressure in the cooling cavity and preventing a large amount of steam from accumulating in the cooling cavity and causing the air pressure to rise.

[0022] 3. As a preferred embodiment of the present utility model, a water inlet is provided at the top of the water tank, and the side wall of the water tank extends obliquely so that the width of the top of the water tank is greater than the width of the bottom of the water tank. The water inlet is used for the user to add water into the water tank, so that there is no need to remove the water tank from the cover body, and the upper part of the water tank is exposed outside the cover body. Therefore, water can be directly injected from the water inlet on the top wall of the water tank. At the same time, the top of the water tank is designed in a flared shape, so that the bottom of the water tank structure is small and the top is large. On the one hand, it further facilitates the user to add water into the water tank through the water inlet at the top. On the other hand, it also improves the guiding effect on the water inside the water tank, making it gradually converge towards the center of the bottom and then drain from the drain port, improving the drainage efficiency.

[0023] 4. As a preferred embodiment of the present utility model, the water tank is made of a transparent material, and a first water level line and a second water level line are provided on the side wall of the water tank. The first water level line corresponds to the amount of water required for the cooking appliance to reduce pressure at the rated working pressure, and the second water level line is located below the first water level line. Since at least part of the water tank is exposed outside the cover body, the user can directly see the water level line of the water tank, which is convenient for adding a sufficient amount of water into the water tank. At the same time, the rated working pressure of the cooking appliance is usually the maximum working pressure. Therefore, the first water level line corresponds to the maximum amount of water required for pressure reduction at the rated working pressure, enabling the user to add water with reference to the first water level line to ensure sufficient water volume during the pressure reduction process from the rated working pressure. And due to the different amounts of ingredients and food in the pot, the amount of cooling water required for pressure reduction is also different. Therefore, a second water level line is provided below the first water level line. When the user cooks a small amount of food, the user can add water with reference to the second water level line, so as to avoid waste caused by excessive water addition and avoid water accumulation on the inner surface of the inner cover while meeting the low-pressure pressure reduction requirements.

[0024] 5. As a preferred embodiment of the present utility model, the pot cover further includes a cover plate detachably fixed to the opening. The cover plate and the cooling area cooperate to enclose a cooling cavity, and the water tank is arranged on the cover plate. When the cover plate is not installed, the cooling area is completely exposed to the outside, and the user can directly wipe and clean the cooling area. At the same time, the cover plate also serves as a mounting bracket for the water tank. By fixing the water tank to the cover plate and then installing the cover plate to the pot cover, the water tank can form a component with the cover plate and be installed and disassembled together, thereby reducing the disassembly and assembly difficulty for the user. And the detachable design of the cover plate enables the user to remove the cover plate and clean it separately, reducing the cleaning pressure and helping to ensure the cleanliness of the cooling cavity. Moreover, structures such as the air outlet can be arranged on the cover plate, which reduces the processing difficulty and ensures the structural unity and beauty of the pot cover.

[0045] Such as Figure 1As shown in the figure, a cooking appliance includes a pot body and a pot lid 1. The pot lid 1 includes a lid body 11 and an inner lid 12. The inner lid 12 cooperates with the pot body to form a cooking cavity. An opening 111 is provided on the top surface of the lid body 11. The top surface of the inner lid 12 has a cooling area 121 corresponding to the opening 111. The lid body 11 is provided with a downwardly extending sealing portion 112. The sealing portion 112 surrounds the outer periphery of the cooling area 121 and abuts and seals against the top surface of the inner lid 12. The cooking appliance further includes a water tank 2 provided on the pot lid 1. At least a part of the water tank 2 is exposed on the upper surface of the lid body 11. The water tank 2, the sealing portion 112 and the cooling area 121 cooperate to enclose a cooling cavity 123. The water tank 2 has a water outlet 22 facing the cooling area 121, so that the water in the water tank 2 flows out from the water outlet 22 to the cooling area 121.

[0046] In the present utility model, an opening 111 is provided on the top surface of the lid body 11, so that a part of the inner lid 12 is exposed to the outside through the opening 111. When the water tank 2 is installed on the lid body 11, the water tank 2 and the cooling area 121 cooperate to form a cooling cavity 123, so that the water in the water tank 2 can directly flow to the cooling area 121 to contact the inner lid 12, and direct heat exchange occurs with the inner lid 12, ensuring the cooling efficiency of the inner lid 12. And when the water tank 2 is not installed, the cooling area 121 is exposed to the outside, and the user can directly wipe and clean the cooling area 121, reducing the cleaning difficulty and helping to keep the inside of the cooling cavity 123 clean.

[0047] At least a part of the water tank 2 is exposed on the upper surface of the lid body 11, so that the user can directly observe the water volume inside the water tank 2 from the outside, and perform operations of adding water and / or discharging water to the water tank 2. This not only saves the internal space of the pot lid 1, avoids the pot lid 1 being structurally bloated and increasing in weight due to the water tank 2 being built into the pot lid 1, but also facilitates the use of the user and improves the user experience.

[0048] In addition, the lid body 11 is provided with a downwardly protruding sealing portion 112 on the outer periphery of the opening 111. The sealing portion 112 abuts and seals against the inner lid 12, so that the cooling cavity 123 is isolated from the internal space of the pot lid 1, and the cooling cavity 123 is located outside the pot lid 1. When cooling the cooling area 121, the heat transfer performance of the inner lid 12 itself can be used to cool other areas of the inner lid 12, but the water in the cooling cavity 123 will not flow into other gaps inside the pot lid 1. Even if there is a small amount of unevaporated water accumulated in the cooling area 121, under the sealing action of the sealing portion 112, even if the pot lid 1 is turned over, the water will not flow into the pot lid 1 and cause uncleanliness. At the same time, the water vapor, smoke, etc. inside the pot lid 1 will not enter the cooling cavity 123, ensuring the cleanliness of the cooling cavity 123 and reducing the cleaning pressure on the user.

[0049] It should be noted that in this specification, taking water as the cooling medium as an example, the present invention is described in detail. However, the present invention does not limit the type of the cooling medium, which can also be a coolant or other liquid media.

[0050] Compared with the scheme of setting a seal 212 in the water tank 2 and forming a cooling chamber 123 by the seal 212 abutting against the inner cover 12 after the water tank 2 is installed, after the water tank 2 is removed from the pot lid 1, the seal 212 and the inner cover 12 lose their sealing, and the cooling chamber 123 formed by the two no longer exists. At this time, the water remaining on the surface of the inner cover 12 will still flow to other areas inside the pot lid 1. In the present invention, whether the water tank 2 is installed or not, the sealing portion 112 of the cover body 11 always abuts against and seals the top surface of the inner cover 12, thereby ensuring the isolation between the cooling area 121 and other areas inside the pot lid 1, and preventing the water in the cooling area 121 from flowing into the pot lid 1.

[0051] It should be noted that the present invention does not limit the way the water in the water tank 2 flows to the cooling area 121 through the water outlet 22. When the water outlet 22 is opened, the water in the water tank 2 can rush into the cooling chamber in a large flow rate or slowly flow to the cooling area 121 in a small water flow. Preferably, the water in the water tank 2 drips onto the cooling area 121 in the form of water droplets through the water outlet 22.

[0052] The water outlet 22 of the water tank 2 drips the water in the water tank 2 onto the surface of the inner cover 12, rather than a large amount of water rushing into the pot lid 1. The volume of the water dripping onto the surface of the inner cover 12 is small, and the contact with the inner cover 12 is more sufficient, so that it can quickly vaporize under the high temperature of the inner cover 12 to form water vapor, reducing the probability of water accumulating on the surface of the inner cover 12.

[0053] In the present invention, the water in the water tank 2 enters the cooling chamber 123 through the water outlet 22, is heated and evaporated to form water vapor. As the water vapor in the cooling chamber 123 increases, the vapor forms an upward push on the seal 212 at the water outlet 22, thereby making the seal 212 tend to block the water outlet 22, further reducing the water outlet speed of the water outlet 22, and further making the water drip onto the cooling area 121 in the form of water droplets.

[0054] The present invention does not limit the structure of the sealing portion 112, and it can be one of the following embodiments:

[0055] Embodiment 1: In this embodiment, as Figure 2 shown, the sealing portion 112 is a rib 1121 extending downward from the edge of the opening 111, and the rib 1121 abuts against the top surface of the inner cover 12.

[0056] As Figure 2As shown, the cover body 11 protrudes downward on the outer periphery of the opening 111 and abuts against the top surface of the inner cover 12 to form a seal. When the water in the cooling area 121 flows here, the water can fill the gap between the rib 1121 and the top surface of the inner cover 12, thereby forming a water seal and further improving the sealing effect.

[0057] Embodiment 2: In this embodiment, the sealing portion 112 includes a sealing ring provided on the cover body 11 and extending downward, and the sealing ring abuts against the top surface of the inner cover 12. The seal is achieved by the abutment of the sealing ring against the inner cover 12. After the sealing ring is deformed by extrusion, the contact effect with the top surface of the inner cover 12 can be improved, thereby improving the sealing effect. At the same time, since the sealing ring is made of an elastic material, it can also compensate for part of the assembly error between the inner cover 12 and the cover body 11, and prevent the hard sealing portion 112 from interfering with the inner cover 12 and causing the inner cover 12 to be unable to be installed with the cover body 11.

[0058] As a preferred embodiment of the present utility model, as Figure 1 、 Figure 3 shown, the cooling area 121 is recessed downward to form a cooling sink 122. The cooling sink 122 cooperates with the water tank 2 to form a cooling cavity 123. The sealing portion 112 surrounds the outer periphery of the cooling sink 122, and the cover body 11 is provided with an air outlet 41 communicating with the cooling cavity 123.

[0059] The setting of the cooling sink 122 makes at least part of the cooling area 121 recessed downward relative to the top surface of the inner cover 12, thereby reducing the position height, enabling the cooling sink 122 to collect the water flowing out of the water tank 2. The liquid in the cooling sink 122 needs to continuously accumulate in the cooling sink 122 until the water level is higher than the side wall of the cooling sink 122 and overflows, and then enters the inside of the pot lid 1 through the sealed portion of the sealing portion 112. In this way, the probability of the water in the cooling cavity 123 flowing into the inside of the pot lid 1 is further reduced. The air outlet 41 is used to discharge the water vapor heated and vaporized in the cooling cavity 123 to ensure the stable air pressure in the cooling cavity 123 and prevent a large amount of steam from accumulating in the cooling cavity 123 and causing the air pressure to rise.

[0060] Preferably, as Figure 4 、 Figure 5 shown, a water outlet switch 21 is provided inside the water tank 2. The upper end of the water outlet switch 21 has an operating portion 211 extending outside the water tank 2, and a sealing member 212 is provided at the lower end of the water outlet switch 21. The water outlet switch 21 can move up and down to block or open the water outlet 22 with the sealing member 212.

[0061] The user manually operates the water outlet switch 21 to control the water tank 2 to drip water into the inner cover 12, making the water cooling and pressure reduction process more controllable. The user can select water cooling at the right time according to needs, improving the use experience.

[0062] Preferably, when the water outlet switch 21 moves upward to its proper position, the sealing member 212 abuts against the bottom wall of the water tank 2 to seal the water outlet 22, and when the water outlet switch 21 moves downward, the sealing member 212 disengages from the bottom wall of the water tank 2, and the water outlet 22 is connected. Specifically, an elastic member 25 is also provided at the water outlet switch 21 to push the water outlet switch 21 to move upward and reset. When the user needs water cooling, the user presses the operating portion 211 of the water outlet switch 21 to move the water outlet switch 21 downward, pushes the bottom sealing member 212 to disengage from the bottom wall of the water tank 2, and the water outlet 22 opens to drip water into the cooling area 121. After the user lets go, the elastic member 25 rebounds the water outlet switch 21 upward to its proper position, and the sealing member 212 abuts against the bottom wall of the water tank 2 again to seal the water outlet 22, so that the water outlet switch 21 remains in a normally closed state.

[0063] Preferably, if Figure 6 As shown, a guide column 26 is provided inside the water tank 2, a guide channel 261 is formed inside the guide column 26, and the water outlet switch 21 is placed in the guide channel 261 and moves up and down along the guide channel 261. The water outlet 22 is opened on the bottom end side wall of the guide column 26, formed by cooperating with the bottom wall of the water tank 2, and there are multiple water outlets 22, which are evenly arranged along the circumference of the guide column 26.

[0064] Furthermore, if Figure 4 , Figure 5 As shown, the water outlet 22 is arranged on the bottom wall of the water tank 2 , and the inner bottom wall of the water tank 2 is provided with a guide slope 23 extending obliquely downward toward the water outlet 22 .

[0065] The water outlet 22 is located at a relatively low height, and the guide slope 23 can guide the water in the water tank 2 to the water outlet 22. When the user presses the water outlet switch 21, the water can flow out quickly without any residual water in the water tank 2. Figure 5 As shown, the water outlet 22 is arranged at the center of the bottom wall of the water tank 2, and the water outlet switch 21 is also arranged at the center of the water tank 2. The bottom wall of the water tank 2 gradually decreases from the peripheral area to the center to form a guide slope 23.

[0066] As a preferred embodiment of the present invention, Figure 5 As shown, a water inlet 27 is provided at the top of the water tank 2 , and the side wall of the water tank 2 extends obliquely so that the width of the top of the water tank 2 is greater than the width of the bottom of the water tank 2 .

[0067] The water inlet 27 is used for the user to add water into the water tank 2, so that there is no need to remove the water tank 2 from the cover body 11. Moreover, the upper part of the water tank 2 is exposed outside the cover body 11. Therefore, water can be directly injected through the water inlet 27 on the top wall of the water tank 2. At the same time, the top of the water tank 2 is designed in a flared shape, making the structure of the water tank 2 smaller at the bottom and larger at the top. On the one hand, it further facilitates the user to add water into the water tank 2 through the water inlet 27 at the top. On the other hand, it also improves the guiding effect on the water inside the water tank 2, making it gradually converge towards the center of the bottom and then drain out through the drain port, improving the drainage efficiency.

[0068] Preferably, as Figure 6 , Figure 7 shown, the top of the water tank 2 is provided with a water inlet 27. The cooking appliance further includes an upper cover 3 connected to the water tank 2. The upper cover 3 can move relative to the water tank 2 to open or close the water inlet 27. By opening the upper cover 3, the user can directly add water into the water tank 2 through the water inlet 27 without removing the water tank 2 from the cover body 11, thus improving the convenience of adding water and the user experience.

[0069] It should be noted that the present utility model does not limit the assembly manner of the water tank 2 and the cover body 11. The water tank 2 can be non-removably connected to the cover body 11, and the user adds water into the water tank 2 through the water inlet 27 at the top of the water tank 2. Preferably, the water tank 2 is removably connected to the cover body 11 so that the user can remove the water tank 2 from the cover body 11 for cleaning. At this time, the user can adopt various water adding methods according to needs. The user can either not remove the water tank 2 from the cover body 11 and directly add water through the water inlet 27 at the top of the water tank 2, or remove the water tank 2 from the cover body 11, add water and then fix the water tank 2 to the cover body 11.

[0070] Specifically, as Figure 7 shown, in one embodiment, the upper cover 3 is rotatably connected to the water tank 2 so that the upper cover 3 can be flipped open or closed to the water inlet 27. Of course, the upper cover 3 can also translate relative to the box body or can be removed from the water tank 2 to open or close the water inlet 27, which is not limited herein.

[0071] As a preferred embodiment of the present utility model, as Figure 8 shown, the water tank 2 is made of a transparent material, and at least one water level mark is provided on the side wall of the water tank 2. Since at least part of the water tank 2 is exposed outside the cover body 11, the user can directly see the water level mark of the water tank 2, thus facilitating the addition of a sufficient amount of water into the water tank 2.

[0072] Furthermore, as Figure 8 shown, the water level mark includes a first water level line 28 and a second water level line 29. The first water level line 28 corresponds to the maximum amount of water required for the cooking appliance to reduce pressure at the rated working pressure. The second water level line 29 is located below the first water level line 28.

[0073] The rated working pressure of the cooking appliance is usually the maximum working pressure. Therefore, the first water level line 28 corresponds to the maximum amount of water required for pressure reduction when at the rated working pressure, enabling the user to add water with reference to the first water level line 28, thus ensuring sufficient water during the pressure reduction process from the rated working pressure and avoiding waste caused by excessive water addition. Due to the different amounts of ingredients and food in the pot, the amount of cooling water required for pressure reduction also varies. Therefore, a second water level line 29 is provided below the first water level line 28. When the user cooks a smaller amount of food, the user can add water with reference to the second water level line 29, thereby avoiding waste caused by excessive water addition and the accumulation of water on the inner surface of the inner lid 12 while meeting the low-pressure pressure reduction requirements.

[0074] Alternatively, the second water level line 29 can also be used as the minimum water level line of the water tank 2, and the user needs to add water into the water tank 2 exceeding the second water level line 29 to meet the function of water-cooled pressure reduction during cooking at a lower pressure.

[0075] In a preferred embodiment, as Figure 8 、 Figure 9 shown, the pot lid 1 further includes a cover plate 4 detachably fixed to the opening 111. The cover plate 4 and the cooling area 121 cooperate to enclose a cooling chamber 123, and the water tank 2 is arranged on the cover plate 4.

[0076] When the cover plate 4 is not installed, the cooling area 121 is completely exposed to the outside, and the user can directly wipe and clean the cooling area 121. At the same time, the cover plate 4 also functions as a mounting bracket for the water tank 2. By fixing the water tank 2 to the cover plate 4 and then installing the cover plate 4 onto the lid body 11, the water tank 2 and the cover plate 4 can form a component for joint installation and disassembly, thereby reducing the installation and disassembly difficulty for the user. Moreover, the detachable design of the cover plate 4 allows the user to remove the cover plate 4 for separate cleaning, reducing the cleaning pressure and helping to ensure the cleanliness of the cooling chamber 123. Not only that, structures such as the air outlet 41 can be arranged on the cover plate 4, thereby reducing the processing difficulty and ensuring the structural unity and aesthetics of the lid body 11.

[0077] Specifically, as Figure 9 shown, the cover plate 4 is provided with an air outlet 41 for timely discharging the water vapor formed by the liquid in the cooling chamber 123 being heated and vaporized, avoiding the increase in air pressure in the cooling chamber 123. In other embodiments, an exhaust gap can also be formed by the cooperation of the cover plate 4 and the lid body 11 for discharging the water vapor. For example, an exhaust gap is formed between the outer peripheral side of the cover plate 4 and the edge of the opening 111, which is not limited herein.

[0078] Preferably, there is a sealing structure between the cover plate 4 and the edge of the opening 111, and the cover plate 4 and the cover body 11 are fixed by interference fit, so as to facilitate the user to install and remove the cover plate 4. Of course, the cover plate 4 can also be fixed to the cover body 11 by other means, such as snap fixation, thread fixation, etc., which are not limited here. Figure 8 As shown, the bottom of the water tank 2 is provided with an inserting rib 24 for inserting and fixing with the cover plate 4.
