Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliances, specifically to a cooking utensil. Background Technology
[0002] Cooking appliances such as steamers (e.g., electric steamers) and steaming baskets use steam to heat food. During the steaming process, water vapor escapes from the gap between the lid and the pot body, resulting in significant heat loss. Furthermore, the cooking cavity is basically at atmospheric pressure, leading to low cooking efficiency.
[0003] In related technologies, it has been proposed to add sealing rings at the joint gaps. However, the flatness requirements of the mating surfaces where the sealing rings are set are high, which makes the processing difficult and costly. Moreover, the addition of sealing rings increases the number of parts, and the sealing rings need to be replaced after a period of use, which makes it inconvenient to use and further increases the cost.
[0004] In related technologies, a concave-convex structure is proposed between the lid and the pot body to form a water seal through the condensation of steam. However, when the pressure inside the cooking cavity is higher than the external pressure, condensation can overflow or even splash from the water seal, affecting cooking results and potentially causing burns to those operating in the environment. Utility Model Content
[0005] This utility model aims to at least partially solve one of the technical problems in the related art.
[0006] Therefore, embodiments of this utility model propose a cooking utensil.
[0007] The cooking appliance of this utility model embodiment includes:
[0008] The system comprises a main body, a juice receiving tray, and a top cover. The juice receiving tray is placed on the main body, and the top cover is placed on the juice receiving tray. The juice receiving tray has a water seal groove and a buffer groove extending circumferentially along the tray. The buffer groove surrounds the water seal groove. When the top cover is placed on the juice receiving tray, the side wall of the top cover extends into the water seal groove to divide the water seal groove into an inner groove portion located inside the side wall of the top cover and an outer groove portion located outside the side wall of the top cover. The inner groove portion and the outer groove portion are connected through a gap between the side wall of the top cover and the bottom wall of the water seal groove. The upper end of the outer groove portion is connected to the buffer groove. The bottom wall of the buffer groove is provided with a return hole, through which water in the buffer groove can flow into the inner cavity of the main body.
[0009] The cooking appliance of this utility model embodiment has a drip tray between the main body and the top cover. The side wall of the top cover extends into the water seal groove to form an inner groove and an outer groove that are connected by a gap. Water forms a water seal between the connected inner groove, the gap and the outer groove, so that a steady gas pressure is generated and maintained in the cooking cavity above the drip tray, thereby improving the cooking effect. The upper end of the outer groove is connected to the buffer groove. When the water forming the water seal overflows, it will flow from the outer groove to the buffer groove. The water in the buffer groove can be discharged through the return hole and flow into the inner cavity of the main body, thereby preventing water from escaping from the cooking appliance and affecting the operating environment or even scalding people. At the same time, the drainage of the buffer groove can enter the inner cavity of the main body for reuse, thereby reducing the water consumption of the cooking appliance.
[0010] Optionally, the top of the main body is provided with a water filling chamber for adding water into the inner cavity of the main body. The water filling chamber is connected to the inner cavity of the main body. The water in the buffer tank flows into the water filling chamber through the return hole and then into the inner cavity of the main body.
[0011] In this embodiment of the cooking appliance, when the drip tray is placed on the main body, water can be added to the inner cavity of the main body through the water filling chamber to ensure the water level in the inner cavity of the main body. The drainage from the buffer tank flows into the water filling chamber and then into the inner cavity of the main body, so that the drainage from the buffer tank can enter the inner cavity of the main body.
[0012] Optionally, the water filling chamber has an opening and a water filling cap for closing and opening the opening. The water filling cap has a hollow portion, and the main body has a water guiding rib for guiding water flowing out of the return hole to the hollow portion.
[0013] The cooking appliance of this utility model has a water filling cover for covering and opening the water filling chamber to facilitate water filling and prevent foreign objects from entering the water filling chamber. The water filling cover has a hollow part to facilitate the drainage of the buffer tank into the water filling chamber. The water guide rib is used to guide the drainage of the buffer tank to the hollow part to prevent the drainage of the buffer tank from flowing out of the water filling chamber.
[0014] Optionally, the juice receiving tray is provided with a first baffle, a second baffle, and a third baffle. The first baffle, the second baffle, and the third baffle extend circumferentially along the juice receiving tray. The second baffle surrounds the first baffle, and the third baffle surrounds the second baffle. The water seal groove is formed between the first baffle and the second baffle, and the buffer groove is formed between the second baffle and the third baffle.
[0015] The cooking appliance of this utility model embodiment has a juice receiving tray with a first baffle, a second baffle, and a third baffle to form a water seal groove and a buffer groove. Water overflowing from the outer groove flows through the top of the second baffle into the buffer groove so that it can be collected by the buffer groove.
[0016] Optionally, the height of the second retaining rib is greater than the height of the first retaining rib and less than or equal to the height of the third retaining rib.
[0017] In this embodiment of the cooking appliance, the height of the second baffle is greater than that of the first baffle. This satisfies the liquid level difference required to form a water seal while also reducing the material cost of the drip tray. The height of the second baffle is less than or equal to that of the third baffle. This ensures that the water overflowing from the outer groove can flow into the buffer groove while also reducing the material cost of the drip tray.
[0018] Optionally, the outer periphery of the side wall of the top cover is provided with a flange, the flange is supported on the top of the third baffle, and the top of the second baffle is spaced apart from the lower surface of the flange.
[0019] The cooking appliance of this utility model embodiment has a flange that can intercept water splashed from the outer groove. The flange is supported on the top of the third baffle to prevent water from overflowing from the buffer tank. The top of the second baffle is spaced apart from the lower surface of the flange to ensure that water overflowing from the outer groove can flow into the buffer tank.
[0020] Optionally, the lower surface of the flange is provided with an upper cover baffle extending circumferentially along the upper cover, the upper cover baffle extending into the buffer groove, the upper cover baffle being spaced apart from the second baffle and the third baffle, and the lower end of the upper cover baffle being spaced apart from the bottom surface of the buffer groove.
[0021] In this embodiment of the cooking appliance, when the pressure inside the cooking cavity above the drip tray is too high, the water flowing from the outer groove to the buffer tank splashes out. The upper cover baffle can stop the water splashing out from the outer groove and intercept it in the buffer tank to prevent overflow from between the third baffle and the flange. Simultaneously, the lower end of the upper cover baffle is spaced apart from the bottom surface of the buffer tank to ensure the water capacity of the buffer tank. Furthermore, when the buffer tank has a return hole, the upper cover baffle also serves to guide the water towards the return hole.
[0022] Optionally, the drip tray includes a tray body and a flange extending outward from the upper edge of the tray body. The first baffle, the second baffle, and the third baffle are disposed on the upper surface of the flange. The flange is supported on the top edge of the main body, and the third baffle is located outside the top edge of the main body.
[0023] In this embodiment of the cooking appliance, the drip tray has a first baffle, a second baffle, and a third baffle on its folded edge to connect with the upper cover and form a water seal. At the same time, the folded edge is supported on the top edge of the main body to connect the upper cover and the main body, and the main body and the upper cover can surround each other to form a closed space, thereby enabling the cooking cavity above the drip tray to form a stable air pressure.
[0024] Optionally, the cooking appliance in this embodiment of the present invention also includes a steaming rack for placing on the drip tray.
[0025] The cooking appliance of this utility model enables steaming by setting a steaming rack, and maintains a stable air pressure in the cooking chamber through a water seal, thereby achieving better steaming effect and efficiency. Meanwhile, the drip tray collects the juices flowing from the steaming rack and the food on it, facilitating cleaning of the cooking appliance.
[0026] Optionally, the cooking appliance in this embodiment of the present invention further includes a latch, which is disposed on at least one of the upper cover and the drip tray, for locking and releasing the upper cover and the drip tray.
[0027] In this embodiment of the invention, the cookware has a lid and a drip tray connected by a locking mechanism to prevent the lid from being lifted and vibrated by the pressure of the cooking cavity above the drip tray.
[0028] Optionally, the main body is provided with a partition rib extending circumferentially along the main body, the partition rib dividing the inner cavity of the main body into a heating cavity and a water storage cavity, the water storage cavity surrounding the heating cavity, and water in the buffer tank flowing into the water storage cavity through the reflux hole; the juice receiving tray is provided with an energy-concentrating rib extending circumferentially along the bottom of the juice receiving tray, the energy-concentrating rib being sleeved on the outer periphery of the partition rib so that the steam passage of the juice receiving tray is opposite to the heating cavity, and the lower surface of the energy-concentrating rib is spaced apart from the bottom surface of the water storage cavity.
[0029] The cooking appliance of this utility model has a heating chamber for heating water to generate steam, and a water storage chamber for replenishing water to the heating chamber to ensure sufficient water supply during cooking. It also receives and stores drainage from the buffer tank for reuse. Simultaneously, water in the water storage chamber can enter between the partition ribs and the energy-concentrating ribs to form a water seal, ensuring that all steam generated in the heating chamber flows through the steam vents into the cooking chamber above the drip tray. This prevents steam from diffusing below the drip tray, thus allowing the upward and downward forces acting on the locking upper cover and drip tray to cancel each other out, preventing the locking upper cover and drip tray from being lifted by steam pressure.
[0030] Optionally, the drip tray has an upwardly protruding hollow boss, and the steam passage is located on the top surface of the boss.
[0031] The cooking appliance of this utility model has a drip tray that guides the steam generated in the heating chamber to the steam passage through an upward-protruding hollow boss, so that the steam flows upward smoothly through the steam passage. The groove formed on the outer periphery of the boss in the drip tray is used to hold cooking juice and condensate to avoid affecting the generation and flow of steam, thereby ensuring the cooking effect.
[0032] Optionally, the bottom surface of the heating chamber is lower than the bottom surface of the water storage chamber, and the heating chamber is connected to the water storage chamber through a water control valve.
[0033] The cooking appliance of this invention controls the liquid level and water volume in the heating chamber via a water control valve, thereby shortening the initial boiling time and improving cooking efficiency. The bottom of the heating chamber is lower than the bottom of the water storage chamber to facilitate water supply from the storage chamber into the heating chamber. Attached Figure Description

[0048] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0049] The following is for reference. Figures 1-8 This invention describes a cooking appliance according to an embodiment of the present invention.
[0050] like Figures 1-8 As shown, the cooking appliance of this utility model embodiment includes a main body 1, a drip tray 2, and a top cover 3.
[0051] The juice receiving tray 2 is placed on the main body 1, and the upper cover 3 is placed on the juice receiving tray 2. The juice receiving tray 2 is provided with a water seal groove 21 and a buffer groove 22 extending circumferentially along the juice receiving tray 2. The buffer groove 22 surrounds the water seal groove 21. When the upper cover 3 is placed on the juice receiving tray 2, the side wall of the upper cover 3 extends into the water seal groove 21 to divide the water seal groove 21 into an inner groove portion 23 located inside the side wall of the upper cover 3 and an outer groove portion 24 located outside the side wall of the upper cover 3. The inner groove portion 23 and the outer groove portion 24 are connected through the gap H0 between the side wall of the upper cover 3 and the bottom wall of the water seal groove 21. The upper end of the outer groove portion 24 is connected to the buffer groove 22. The bottom wall of the buffer groove 22 is provided with a return hole 25, and the water in the buffer groove 22 can flow into the inner cavity of the main body 1 through the return hole 25.
[0052] like Figures 1-5 As shown, the main body 1 is preferably, but not limited to, a pot body, a casserole body, etc. The inner cavity of the main body 1 preferably, but not limited to, forms an inner cavity opening at the top of the main body 1. The drip tray 2 can be placed and removed from the top of the main body 1, and the top cover 3 can be placed and removed from the drip tray 2, so that the drip tray 2 is connected between the main body 1 and the top cover 3, forming a closed space. The part of the closed space above the drip tray 2 forms a cooking cavity.
[0053] Juice tray 2 is provided with a circumferential (e.g.) Figure 2 The water seal trough 21 and the buffer trough 22 extend in the direction of verticality. The buffer trough 22 surrounds the water seal trough 21. In other words, the buffer trough 22 is located on the outer periphery of the water seal trough 21. In other words, both the water seal trough 21 and the buffer trough 22 are annular in the vertical direction. The buffer trough 22 is located on the side of the water seal trough 21 away from the vertical center line of the drip tray 2.
[0054] The bottom wall of the buffer tank 22 is provided with a return hole 25. The return hole 25 preferably penetrates the bottom wall of the buffer tank 22 in a vertical direction. The return hole 25 can drain the water in the buffer tank 22 into the inner cavity of the main body 1.
[0055] When the top cover 3 is placed on the juice receiving tray 2, the side wall of the top cover 3 extends into the water seal groove 21, and there is a gap H0 between the bottom surface of the side wall of the top cover 3 and the bottom surface of the water seal groove 21. The side wall of the top cover 3 divides the water seal groove 21 into an inner groove portion 23 and an outer groove portion 24. The inner groove portion 23 is located on the inner side of the side wall of the top cover 3, and the outer groove portion 24 is located on the outer side of the side wall of the top cover 3. In other words, the inner groove portion 23 is formed by the portion of the water seal groove 21 located on the inner side of the side wall of the top cover 3, and the outer groove portion 24 is formed by the portion of the water seal groove 21 located on the outer side of the side wall of the top cover 3. The outer groove portion 24 is located on the side of the inner groove portion 23 away from the vertical center line of the juice receiving tray 2. In other words, the outer groove portion 24 is located between the inner groove portion 23 and the buffer groove 22. The bottom of the inner groove 23 and the bottom of the outer groove 24 are connected by a gap H0, so that the water in the water seal groove 21 can form a water seal between the connected inner groove 23, gap H0 and outer groove 24. The upper end of the outer groove 24 is connected to the buffer groove 22.
[0056] When using the cooking appliance, water can be poured into the water seal groove 21 first, and then the top cover 3 can be placed on the drip tray 2 to form a water seal. This allows the cooking cavity to form a slight pressure when cooking begins, improving cooking efficiency. Alternatively, the top cover 3 can be placed on the drip tray 2 first, and then during cooking, the condensate formed on the inner wall of the top cover 3 flows along the side wall of the top cover 3 into the water seal groove 21 to form a water seal, thereby creating a slight pressure in the cooking cavity.
[0057] When the pressure inside the cooking cavity is too high and forces the water in the water seal 21 to flow out of the outer tank 24, or when the power of the cooking appliance fluctuates or the cooking appliance vibrates due to internal components or external forces, causing the water in the water seal 21 to fluctuate and flow out of the outer tank 24, the water flowing out of the outer tank 24 is collected by the buffer tank 22. The water in the buffer tank 22 flows into the inner cavity of the main body 1 through the return hole 25, thereby preventing water from escaping from the cooking appliance and enabling the drainage of the buffer tank 22 to be reused.
[0058] The cooking appliance of this utility model embodiment has a drip tray 2 between the main body 1 and the upper cover 3. The side wall of the upper cover 3 extends into the water seal groove 21 to form an inner groove 23 and an outer groove 24 connected by a gap H0. Water forms a water seal between the connected inner groove 23, gap H0 and outer groove 24, so that a steady gas pressure is generated and maintained in the cooking cavity above the drip tray 2, thereby improving the cooking effect. The upper end of the outer groove 24 is connected to the buffer groove 22. When the water forming the water seal overflows, it will flow from the outer groove 24 into the buffer groove 22. The water in the buffer groove 22 can be discharged through the return hole 25 and flow into the inner cavity of the main body 1, thereby preventing water from escaping from the cooking appliance and affecting the operating environment or even scalding people. At the same time, the drainage of the buffer groove 22 can enter the inner cavity of the main body 1 for reuse, thereby reducing the water consumption of the cooking appliance.
[0059] Optionally, the top of the main body 1 is provided with a water filling chamber 11 for adding water into the inner cavity of the main body 1. The water filling chamber 11 is connected to the inner cavity of the main body 1. The water in the buffer tank 22 flows into the water filling chamber 11 through the return hole 25 and then into the inner cavity of the main body 1.
[0060] like Figures 1-5 As shown, the top of the main body 1 is provided with a water filling cavity 11, which is connected to the inner cavity of the main body 1. When the drip tray 2 is placed on the main body, water can be added to the inner cavity of the main body 1 through the water filling cavity 11 without having to remove the top cover 3 and the drip tray 2 to add water, which is convenient for cooking operations.
[0061] The return hole 25 allows water in the buffer tank 22 to be drained into the water filling chamber 11. The water in the buffer tank 22 first flows into the water filling chamber 11 through the return hole 25, and then flows into the inner cavity of the main body 1 from the water filling chamber 11. Thus, the water filling chamber 11 facilitates the drainage of the buffer tank 22 into the inner cavity of the main body 1 for reuse.
[0062] Optionally, the water filling chamber 11 has an opening and a water filling cover 4 for closing and opening the opening. The water filling cover 4 has a hollow portion 41, and the main body 1 has a water guiding rib 12 for guiding water flowing out of the return hole 25 to the hollow portion 41.
[0063] like Figures 1-5 As shown, the water filling cavity 11 preferably has an opening at the top, which is opened and closed by the water filling cover 4. The water filling cover 4 can be pivotally connected to the main body 1 so that the water filling cavity 11 can be opened and closed by rotating the water filling cover 4. The water filling cover 4 can also be movably connected to the main body 1 so that the water filling cavity 11 can be opened and closed by pushing and pulling the water filling cover 4. When the water filling cavity 11 is open, water can be added to the inner cavity of the main body 1 through the water filling cavity 11 without removing the upper cover 3 and the drip tray 2 to add water, which is convenient for cooking operations. The water filling cover 4 also serves to prevent foreign objects from entering the inner cavity of the main body 1 through the water filling cavity 11.
[0064] The reflux hole 25, the water filling chamber 11, and the water filling cover 4 are preferably, but not limited to, being arranged along the... Figure 2 and Figure 3 The strip extending in the left and right direction, the return hole 25 and the water filling chamber 11 are as shown. Figure 2 and Figure 3 As shown in the front-to-back arrangement, the water filler cap 4 has a hollowed-out portion 41 at its rear end facing the water inlet. In other words, the hollowed-out portion 41 is a groove provided on the rear end face of the water filler cap 4. The hollowed-out portion 41 penetrates the water filler cap 4 vertically.
[0065] The main body 1 forms a guide surface 17 between the return hole 25 and the water filling chamber 11. The guide surface 17 is preferably, but not limited to, an inclined surface or an arc surface, and more preferably a guide surface 17. Both the left and right ends of the guide surface 17 are provided with water guiding ribs 12. The drainage from the return hole 25 flows to the hollow part 41 under the guidance of the guide surface 17 and the water guiding ribs 12, and enters the water filling chamber 11 through the hollow part 41 without opening the water filling cover 4, while preventing the drainage from the return hole 25 from flowing outside the water filling chamber 11.
[0066] It is understood that the hollow part 41 is not limited to being provided at the rear end of the water filling cover 4. In other embodiments, the water filling cover 4 is moved by pushing and pulling to open and close the water filling chamber 11. When the water filling cover 4 closes the water filling chamber 11, the return hole 25 is located directly above the water filling cover 4. The middle part of the water filling cover 4 is provided with a hole as the hollow part 41 so that the hollow part 41 and the return hole 25 are arranged opposite each other in the vertical direction.
[0067] Optionally, the juice receiving tray 2 is provided with a first baffle 26, a second baffle 27 and a third baffle 28. The first baffle 26, the second baffle 27 and the third baffle 28 extend along the circumference of the juice receiving tray 2. The second baffle 27 surrounds the first baffle 26 and the third baffle 28 surrounds the second baffle 27. A water seal groove 21 is formed between the first baffle 26 and the second baffle 27, and a buffer groove 22 is formed between the second baffle 27 and the third baffle 28.
[0068] like Figures 4-6 As shown, the juice receiving tray 2 is provided with a first baffle 26, a second baffle 27 and a third baffle 28. The first baffle 26, the second baffle 27 and the third baffle 28 extend along the circumference of the juice receiving tray 2. In other words, the first baffle 26, the second baffle 27 and the third baffle 28 are all rings around the vertical direction, and can be circular rings, elliptical rings, rectangular rings, rounded rectangular rings, etc.
[0069] The second baffle 27 surrounds the first baffle 26, and the third baffle 28 surrounds the second baffle 27. In other words, the first baffle 26, the second baffle 27, and the third baffle 28 are arranged alternately in the horizontal plane from the inside to the outside.
[0070] A water seal groove 21 is formed between the first baffle 26 and the second baffle 27, and a buffer groove 22 is formed between the second baffle 27 and the third baffle 28. Water overflowing from the outer groove 24 flows through the top of the second baffle 27 into the buffer groove 22 for collection.
[0071] Optionally, the height of the second retaining rib 27 is greater than the height of the first retaining rib 26 and less than or equal to the height of the third retaining rib 28.
[0072] like Figure 5 As shown, the height H1 of the first baffle 26 is less than the height H2 of the second baffle 27, so as to reduce the material cost of the drip tray 2 while satisfying the liquid level difference required to form a water seal.
[0073] The height H2 of the second baffle 27 is less than or equal to the height H3 of the third baffle 28. Preferably, the height H2 of the second baffle 27 is less than the height H3 of the third baffle 28. This ensures that water overflowing from the outer trough 24 can flow into the buffer trough 22 while also reducing the material cost of the drip tray 2.
[0074] Optionally, the outer periphery of the side wall of the top cover 3 is provided with a flange 31, which is supported on the top of the third baffle 28, and the top of the second baffle 27 is spaced apart from the lower surface of the flange 31.
[0075] like Figure 4 , Figure 5 and Figure 8 As shown, the outer periphery of the side wall of the upper cover 3 is provided with a flange 31. The flange 31 is preferably, but not limited to, an annular shape extending circumferentially along the upper cover 3. When the upper cover 3 is placed on the drip tray 2, the flange 31 is supported on the top of the third baffle 28. In other words, the lower surface of the flange 31 abuts against the top surface of the third baffle 28. The top of the second baffle 27 is spaced apart from the lower surface of the flange 31 to form a shape as shown in the image. Figure 5 The interval H4 shown means that the height H2 of the second retaining rib 27 is less than the height H3 of the third retaining rib 28.
[0076] When the top cover 3 is placed on the drip tray 2, the interval H4 ensures that the water overflowing from the outer groove 24 can flow smoothly into the buffer groove 22. When the pressure inside the cooking cavity is too high and water splashes outward from the outer groove 24, the flange 31 can also intercept the splashed water in the buffer groove 22. The flange 31 is supported on the top of the third baffle 28 and can also prevent water from overflowing from the buffer groove 22.
[0077] Optionally, the lower surface of the flange 31 is provided with an upper cover baffle 32 extending circumferentially along the upper cover 3. The upper cover baffle 32 extends into the buffer groove 22. The upper cover baffle 32 is spaced apart from the second baffle 27 and the third baffle 28. The lower end of the upper cover baffle 32 is spaced apart from the bottom surface of the buffer groove 22.
[0078] like Figure 5and Figure 8 As shown, the lower surface of the flange 31 is provided with a protruding upper cover baffle 32, which extends circumferentially along the upper cover 3. In other words, the upper cover baffle 32 is annular around the vertical direction.
[0079] When the upper cover 3 is placed on the drip tray 2, the upper cover baffle 32 extends into the buffer groove 22 and is spaced apart from both the second baffle 27 and the third baffle 28. The upper cover baffle 32 is located outside the interval H4; in other words, the upper cover baffle 32 is positioned opposite to the interval H4. Preferably, the height H5 of the upper cover baffle 32 is greater than or equal to the interval H4, and more preferably greater than the interval H4. When the pressure in the cooking cavity above the drip tray 2 is too high, the water flowing from the outer groove 24 to the buffer groove 22 splashes. The upper cover baffle 32 can stop the splashing water and intercept it in the buffer groove 22 to prevent water from overflowing between the third baffle 28 and the flange 31.
[0080] The lower end of the top cover baffle 32 is spaced apart from the bottom surface of the buffer tank 22 to ensure the water capacity of the buffer tank 22 and to prevent the top cover baffle 32 from causing the volume of the buffer tank 22 to shrink too much.
[0081] The upper cover baffle 32 is located above the return hole 25. The upper cover baffle 32 extends from the lower surface of the flange 31 toward the return hole 25. It can be set straight or inclined to guide the water discharged at interval H4 to the return hole 25 so that the water in the buffer tank 22 can be discharged through the return hole 25.
[0082] Optionally, the juice receiving tray 2 includes a tray body 29 and a flange 210 extending outward from the upper edge of the tray body 29. A first baffle 26, a second baffle 27 and a third baffle 28 are provided on the upper surface of the flange 210. The flange 210 is supported on the top edge of the main body 1, and the third baffle 28 is located outside the top edge of the main body 1.
[0083] like Figure 4 and Figure 5 As shown, the drip tray 2 includes a tray body 29 and a flange 210. The flange 210 extends outward from the upper edge of the tray body 29 and surrounds the tray body 29. The first baffle 26, the second baffle 27 and the third baffle 28 are all provided on the upper surface of the flange 210 and are arranged sequentially from the inside to the outside along the horizontal plane, thereby forming a water seal groove 21 and a buffer groove 22 for placing the top cover 3.
[0084] When the drip tray 2 is placed on the main body 1, the flange 210 is supported on the top edge of the main body 1; in other words, the bottom surface of the flange 210 abuts against the top surface of the main body 1. Furthermore, the third retaining rib 28 is located on the outer side of the top edge of the main body 1.
[0085] The drip tray 2 is stably supported on the main body 1, connecting the upper cover 3 and the main body 1, and allowing the main body 1 and the upper cover 3 to form a closed space, thereby creating a stable air pressure in the cooking cavity above the drip tray 2. At the same time, the third baffle 28, located on the outer side of the top edge of the main body 1, also facilitates the installation of the return hole 25, allowing the drainage from the return hole 25 to be guided to the hollow part 41 by the water guide rib 12.
[0086] Optionally, the cooking appliance in this embodiment of the present invention also includes a steaming rack 5 for placing on the drip tray 2.
[0087] like Figure 2 and Figure 4 As shown, the cooking appliance in this embodiment of the present invention also includes a steaming rack 5, which is used to be placed on the drip tray 2 and located in the cooking cavity above the drip tray 2.
[0088] The steaming rack 5 enables the cooking utensils to steam and boil, and the water seal between the drip tray 2 and the top cover 3 maintains a stable air pressure in the cooking chamber, resulting in better steaming and boiling effects and efficiency. At the same time, the drip tray 2 can collect the juices flowing from the steaming rack 5 and the food on it, making it easier to clean the cooking utensils.
[0089] Optionally, the cooking appliance in this embodiment of the present invention further includes a latch 6, which is disposed on at least one of the upper cover 3 and the drip tray 2, for locking and releasing the upper cover 3 and the drip tray 2.
[0090] like Figure 1 and Figure 2 As shown, the juice receiving tray 2 is along the edge as... Figure 2 Both ends shown in the left and right directions are equipped with latches 6, and the top cover 3 is along the edge as shown in the figure. Figure 2 Both ends of the left and right directions shown are provided with fastening seats 33. The fastening seats 33 are preferably, but not limited to, provided on the flange 31. The latch 6 is correspondingly provided with the fastening seats 33 and can be fastened and separated. Specifically, the latch 6 can be pivotally connected to the juice tray 2 for fastening and separation, or it can be slidably connected to the juice tray 2 for fastening and separation.
[0091] It is understandable that the latch 6 can also be located on the upper cover 3, and the drip tray 2 is provided with a latch seat 33.
[0092] When the top cover 3 is placed on the drip tray 2, the latch 6 engages with the fastening seat 33 to lock the top cover 3 and the drip tray 2, and then cooking is carried out. After cooking is completed, first separate the latch 6 from the fastening seat 33, and then separate the top cover 3 from the drip tray 2.
[0093] The latch 6 locks the top cover 3 and the drip tray 2 during cooking to prevent the top cover 3 from being lifted and vibrating when the pressure inside the cooking cavity is too high, thus avoiding potential safety hazards.
[0094] It is understood that the upper cover 3 and the juice tray 2 are not limited to being connected by the latch 6. In other embodiments, the upper cover 3 and the juice tray 2 are threaded together, for example, the flange 31 is threaded together with the third retaining rib 28.
[0095] Optionally, the main body 1 is provided with a partition rib 13 extending circumferentially within the main body 1. The partition rib 13 divides the inner cavity of the main body 1 into a heating cavity 14 and a water storage cavity 15. The water storage cavity 15 surrounds the heating cavity 14, and water in the buffer tank 22 can flow into the water storage cavity 15 through the return hole 25. The juice receiving tray 2 is provided with a concentrating rib 211 extending circumferentially below the juice receiving tray 2. The concentrating rib 211 is sleeved on the outer periphery of the partition rib 13 so that the steam passage 212 of the juice receiving tray 2 is opposite to the heating cavity 14, and the lower surface of the concentrating rib 211 is spaced apart from the bottom surface of the water storage cavity 15.
[0096] like Figure 2 and Figure 4 As shown, the bottom of the inner cavity of the main body 1 is provided with an upwardly extending partition rib 13. The partition rib 13 extends circumferentially along the main body 1; in other words, the partition rib 13 is annular around the vertical direction. The partition rib 13 divides the inner cavity of the main body 1 into a heating cavity 14 and a water storage cavity 15. The water storage cavity 15 surrounds the heating cavity 14; in other words, the water storage cavity 15 is located outside the partition rib 13, and the heating cavity 14 is located inside the partition rib 13. The water filling cavity 11 is located above and connected to the water storage cavity 15, so as to add water to the water storage cavity 15 through the water filling cavity 11.
[0097] The heating chamber 14 is used to heat water to generate steam, and the water storage chamber 15 is used to replenish water to the heating chamber 14 to ensure the amount of water in the heating chamber 14 during cooking.
[0098] Preferably, the bottom of the heating chamber 14 is provided with a heating element 9 for heating the water in the heating chamber 14.
[0099] The water filling chamber 11 is located at the top of the main body 1 and above the water storage chamber 15. The water filling chamber 11 is connected to the water storage chamber 15. The water in the buffer tank 22 first flows into the water filling chamber 11 through the return hole 25, and then flows into the water storage chamber 15 for storage, so that it can be replenished to the heating chamber 14 for reuse, thereby reducing the amount of water added to the water storage chamber 15.
[0100] Figure 6 and Figure 7 As shown, the juice receiving tray 2 is provided with a steam through hole 212 that runs vertically through it, and the bottom of the juice receiving tray 2 is provided with a protruding energy-concentrating rib 211. The energy-concentrating rib 211 extends along the circumference of the juice receiving tray 2. In other words, the energy-concentrating rib 211 is a ring around the vertical direction.
[0101] like Figure 4As shown, when the juice receiving tray 2 is placed on the main body 1, the steam passage 212 of the juice receiving tray 2 is vertically opposite to the heating chamber 14. The energy-concentrating rib 211 is sleeved on the outer periphery of the partition rib 13 and spaced apart from the partition rib 13. The lower surface of the energy-concentrating rib 211 is spaced apart from the bottom surface of the water storage chamber 15 and forms a shape as shown in the figure. Figure 4 The interval H6 is shown.
[0102] During cooking, the heating chamber 14 is connected to the cooking chamber through the steam vent 212. Water in the water storage chamber 15 enters between the partition rib 13 and the energy-concentrating rib 211 through the spacer H6 and forms a water seal, so that the connected heating chamber 14 and the cooking chamber form a sealed space. All the steam generated by the heating chamber 14 flows through the steam vent 212 into the cooking chamber above the drip tray 2, preventing the steam generated by the heating chamber 14 from diffusing below the drip tray 2. The steam in the cooking chamber exerts an upward force on the upper cover 3 and a downward force on the drip tray 2. Since the upper cover 3 and the drip tray 2 are connected as a whole by the latch 6, and the upper cover 3 and the drip tray 2 also have a certain weight, the upward force and the downward force on the upper cover 3 and the drip tray 2 connected by the latch 6 can cancel each other out, thereby preventing the upper cover 3 and the drip tray 2 connected by the latch 6 from being lifted off the main body 1 by the steam pressure.
[0103] Furthermore, the spacing H6 ≤ 3 mm is maintained to prevent the liquid level in the water storage cavity 15 from falling below the lower surface of the energy-concentrating rib 211 during cooking, which would cause air to enter between the separating rib 13 and the energy-concentrating rib 211 and cause the water seal to fail.
[0104] Preferably, 1 mm ≤ H6 ≤ 3 mm, for example, 1 mm, 2 mm, or 3 mm. H6 ≤ 3 mm can prevent air from entering between the partition rib 13 and the energy-concentrating rib 211, causing the water seal to fail. 1 mm ≤ H6 can prevent the gap H6 from being blocked by foreign objects in the water, thus affecting the water seal effect.
[0105] In other embodiments, the drip tray 2 and the main body 1 can also be connected by another latch 6 or by a threaded connection to prevent the drip tray 2 from being lifted by steam pressure.
[0106] Optionally, the drip tray 2 has an upwardly protruding hollow boss 213, and a steam through hole 212 is provided on the top surface of the boss 213.
[0107] like Figure 4 and Figure 6 As shown, the juice receiving tray 2 has a hollow boss 213 protruding upward in the middle. When the juice receiving tray 2 is placed on the main body 1, the boss 213 and the heating chamber 14 are arranged opposite to each other in the vertical direction and are connected. The top surface of the boss 213 is provided with a steam passage hole 212.
[0108] During cooking, the boss 213 guides the steam generated by the heating chamber 14 to the steam passage 212 so that the steam flows smoothly upward through the steam passage 212 to the cooking chamber. The groove formed on the outer periphery of the drip tray 2 on the boss 213 is used to hold cooking juice and condensate to avoid affecting the generation and flow of steam, thereby ensuring the cooking effect.
[0109] Meanwhile, since the height H1 of the first baffle 26 is less than the height H2 of the second baffle 27, when the amount of condensate flowing along the side wall of the upper cover 3 to the water seal groove 21 is too large, the water in the water seal groove 21 can overflow through the first baffle 26 into the groove of the drip tray 2, thereby reducing the amount of water flowing into the buffer tank 22 from the water seal groove 21.
[0110] Optionally, the bottom surface of the heating chamber 14 is lower than the bottom surface of the water storage chamber 15, and the heating chamber 14 is connected to the water storage chamber 15 through the water control valve 7.
[0111] like Figure 2 and Figure 4 As shown, the main body 1 has a connecting channel 16, which is located between the heating chamber 14 and the water storage chamber 15, connecting the two chambers. A water control valve 7 is located in the connecting channel 16 to control the flow of water from the water storage chamber 15 to the heating chamber 14. Thus, the water control valve 7 controls the liquid level and water volume in the heating chamber 14, shortening the initial boiling time during cooking and improving cooking efficiency.
[0112] The bottom surface of the heating chamber 14 is lower than the bottom surface of the water storage chamber 15, which facilitates the supply of water from the water storage chamber 15 into the heating chamber 14.
[0113] Optionally, a pressure relief valve 8 is provided on the upper cover 3.
[0114] like Figure 4 As shown, the upper cover 3 is equipped with a pressure relief valve 8. During the cooking process, the pressure in the cooking chamber is controlled by the pressure relief valve 8 to avoid excessive pressure in the cooking chamber and potential safety hazards.
