Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and more specifically, to a base assembly and a cooking device. Background Technology

[0002] When cooking in a current electric steamer, the steam temperature inside the cooking chamber typically only reaches a maximum of 100℃. This results in a longer cooking time for meat or grains. Raising the steam temperature inside the cooking chamber to over 100℃ would increase heat exchange between the steam and the food, thus shortening the cooking time. While existing flow-type or hot pot-type heaters can generate high-temperature steam above 100℃, their closed structure makes them difficult for users to clean after limescale buildup. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, firstly, this utility model proposes a base assembly for a cooking device having a cooking cavity. The base assembly includes: a base; a water tank assembly disposed within the base; a heating assembly disposed within the water tank assembly, the heating assembly including a heater and a heating element, the heating element being used to heat the water in the water tank assembly and the heater, the heater having a heating channel within it, the top of the heating channel having an opening, the heating channel being connected to the water tank assembly; and a drip tray disposed on the heater, the drip tray sealing the opening, the drip tray having a steam outlet, the steam flowing into the heating channel flowing into the cooking cavity through the steam outlet.

[0005] The heating element is located inside the water tank assembly. During operation, it heats the water in the tank to generate steam. A heating channel is located inside the heater, connected to the water tank assembly. Steam from the tank flows into the heating channel. Since the heating element also heats the heater, the steam flowing into the channel is further heated, effectively increasing its temperature. The heated steam exits the heating channel and flows through the vent on the drip tray into the cooking chamber, thus heating the food inside. This method allows the steam discharged into the cooking chamber to reach temperatures above 100°C, shortening cooking time, increasing efficiency, and preventing nutrient loss.

[0006] The top of the heating channel is open, meaning that the heating channel in this solution is not a closed structure. Users can easily clean the inside of the heater, and can promptly remove scale and impurities inside the heater to ensure its cleanliness.

[0007] When using the heating element, the drip tray is placed on top of the heater. The drip tray seals the opening at the top of the heating channel, preventing external impurities from entering. Furthermore, after steam flows into the heating channel from the water tank assembly, the sealed top of the heating channel allows the heated steam to escape only through the vent, preventing it from flowing back into the water tank assembly and thus avoiding heat waste. Additionally, sealing the opening at the top of the heating channel facilitates more thorough heating of the steam by the heating element, increasing the steam temperature and reducing the impact of steam pressure on the stability of the drip tray.

[0008] In addition, the base assembly according to the above-described technical solution provided by this utility model may also have the following additional technical features:

[0009] In some technical solutions, optionally, the water tank assembly includes a water tank body and a water-proof rib. The water-proof rib is located inside the water tank body and divides the water tank body into a water supply chamber and a heating chamber. The water supply chamber and the heating chamber are connected, and the heating component is located inside the heating chamber.

[0010] The water-blocking ribs divide the interior of the water tank into a water replenishment chamber and a heating chamber. After some of the water in the heating chamber is heated into steam, the water replenishment chamber can replenish water to the heating chamber at any time to ensure that there is enough water in the heating chamber and avoid the problem of dry burning in the heating chamber.

[0011] A small space (heating chamber) is defined within the water tank body by water-proof ribs, which allows the water in the heating chamber to be heated quickly, thus improving the steam generation rate.

[0012] In some technical solutions, optionally, the juice receiving tray is placed on the heater, and the water tank body and the water-proof rib are spaced apart from the juice receiving tray; or the juice receiving tray is placed on the heater and the water-proof rib, and the water tank body and the juice receiving tray are spaced apart, with the water-proof rib and the juice receiving tray in close contact and sealing.

[0013] When the drip tray is placed on the heater, it contacts the top of the heater, sealing the opening through its contact with the heater. To improve the sealing effect, the water tank body and the water-proof rib are spaced apart from the drip tray. That is, the drip tray only rests on the heater, not on the water tank body or the water-proof rib. Due to dimensional errors in the manufacturing of various components, by leaving gaps between the water tank body and the water-proof rib and the drip tray, it is ensured that all components are within dimensional tolerances. The drip tray can seal the top opening of the heating channel, and the water tank body and the water-proof rib will not obstruct the downward placement of the drip tray, ensuring that the drip tray can fit tightly against the heater.

[0014] Alternatively, the water tank body and the drip tray can be spaced apart, with the drip tray resting on the heater and the baffle rib. This allows the drip tray to not only seal the top opening of the heater but also the top of the heating chamber, preventing steam from flowing into the water supply chamber from the top of the baffle rib.

[0015] In the above method, no other parts are needed to connect the juice tray and the heater, making it easy to remove the juice tray and clean the heater.

[0016] In some technical solutions, optionally, the drip tray and the heater are sealed by a sealing component.

[0017] A sealing component can be added between the juice tray and the heater to improve the sealing performance between them.

[0018] In some technical solutions, optionally, the juice receiving tray is provided with a limiting part, which cooperates with the heater to limit the translation of the juice receiving tray relative to the heater.

[0019] When the drip tray is placed on the heater, the limiting part on the drip tray is located on one side of the heater. When the drip tray is normally in use, the limiting part will fit against the heater. The heater restricts the movement of the limiting part, thereby restricting the drip tray from moving relative to the heater. This ensures that the drip tray is not easily dislodged from its installation position, avoids misalignment between the air outlet on the drip tray and the outlet of the heating channel, and ensures that the steam in the heating channel can be stably discharged through the air outlet.

[0020] In some technical solutions, optionally, the limiting part protrudes from the surface of the juice receiving tray, and the heater is located on the side of the limiting part away from the edge of the juice receiving tray.

[0021] The limiting part has a raised structure, and the heater is located on the inner side of the limiting part. The raised limiting part restricts the juice tray from moving relative to the heater, ensuring that the juice tray is not easily dislodged from the installation position.

[0022] In some technical solutions, optionally, the juice receiving tray includes: a juice receiving tray body, a boss disposed on the juice receiving tray body, the boss being higher than the top surface of the juice receiving tray body, an air outlet disposed on the boss, the boss being disposed on the heater, and the boss sealing the opening.

[0023] The drip tray is placed on the heater. During cooking, the juices produced by the food will drip onto the drip tray. The drip tray collects and holds the juices, making it convenient for users to clean up the juices from the food and preventing the juices from flowing into the water tank assembly and contaminating the water inside the water tank assembly.

[0024] In this design, a boss is provided on the juice receiving tray body, protruding from the top surface of the juice receiving tray body. The air outlet is located on the boss, so the air outlet is also higher than the top surface of the juice receiving tray. When the amount of juice collected on the juice receiving tray body increases, the juice on the juice receiving tray body is less likely to flow into the air outlet, thereby preventing the juice from flowing into the heater through the air outlet, reducing the workload of cleaning the inside of the heater for the user, and making it more convenient for the user.

[0025] In this design, the boss is placed on the heater to seal the opening.

[0026] In some technical solutions, optionally, the projection surface is set to extend horizontally, and the boss and heater are projected onto the projection surface, with the projection of the heater located within the projection range of the boss.

[0027] Since the heater's projection is located within the projection range of the boss, the boss's horizontal projection is larger than the heater's horizontal projection, thus allowing for a certain installation deviation margin for the drip tray. The purpose is that even if the drip tray is not placed in the center, the boss can still close the top opening of the heating channel.

[0028] In some technical solutions, the boss may be integrally formed into the juice tray body; or the boss may be detachably connected to the juice tray body.

[0029] The boss can be integrally formed with the juice tray body. A part of the juice tray body is bent away from the heater, thereby forming the boss on the juice tray body. The boss and the juice tray body are not easily separated, ensuring the structural stability of the juice tray.

[0030] A separate component can be used as a boss, which is locked onto the drip tray body. When the inside of the heater needs to be cleaned, the boss can be removed from the drip tray body to open the opening at the top of the heater. During this process, the drip tray does not need to be removed, making it convenient for the user to operate.

[0031] In some technical solutions, the drip tray body optionally includes: a bottom wall and a side wall, the side wall being connected to the edge of the bottom wall, at least a portion of the side wall being higher than the bottom wall, and the air outlet being higher than the top of the side wall.

[0032] The bottom wall is provided with side walls at its edge, and at least a part of the side walls is higher than the bottom wall, so that the bottom wall and the side walls enclose a receiving space, and the juice collected on the juice tray does not easily flow to the outside of the juice tray body.

[0033] As the amount of juice collected in the drip tray increases, the liquid level on the drip tray gradually rises. In this design, the vent is positioned above the top of the side wall, ensuring that even when the drip tray is full of water, the vent remains above the liquid level, preventing the medium from entering the heater through the vent.

[0034] In some technical solutions, the base assembly may optionally include a steam cylinder connected to the drip tray, with the first end of the steam cylinder connected to the air outlet and the second end of the steam cylinder extending into the heating channel, through which the steam in the heating channel flows to the air outlet.

[0035] A steam cylinder is installed inside the heater. The steam entering the heating channel must first pass through the steam cylinder before flowing to the outlet.

[0036] By incorporating a heat-conducting cylinder within the heater, the steam flowing into the heating channel does not directly exit the outlet but instead first enters the heat-conducting cylinder. This prolongs the steam's flow time within the heater. The longer the steam flows within the heater, the longer it is reheated, effectively increasing its temperature. Through this method, the steam discharged into the cooking chamber can reach temperatures above 100°C, shortening cooking time and accelerating cooking efficiency.

[0037] In some technical solutions, the first end of the steam cylinder may be integrally formed with the juice receiving tray; or the first end of the steam cylinder may be sealed to the juice receiving tray.

[0038] One end of the steam cylinder is connected to the drip tray, making the steam cylinder and drip tray an integral structure. This prevents the steam cylinder from easily separating from the drip tray and ensures the structural stability of the drip tray. Furthermore, since the steam cylinder is integrally formed into the drip tray, no other sealing structure is needed between the steam cylinder and the drip tray, ensuring a tight seal between them and preventing steam from escaping through gaps. This ensures that the steam in the heating channel passes through the steam cylinder.

[0039] The steam cylinder and the drip tray can also be designed separately, but the steam cylinder and the drip tray need to be sealed to prevent steam from escaping through the gaps between them.

[0040] In some technical solutions, optionally, the second end of the steam cylinder is spaced apart from the bottom wall of the heating channel, and the steam in the heating channel flows into the steam cylinder through the second end of the steam cylinder.

[0041] The second end of the steam cylinder is the bottom of the steam cylinder. An opening is provided at the bottom of the steam cylinder, so that the steam in the heating channel flows into the steam cylinder through the bottom of the steam cylinder. The steam in the heating channel first flows downward to the bottom of the steam cylinder, and then flows upward in the steam cylinder. In this way, the flow path of the steam in the heater is further extended.

[0042] In some technical solutions, optionally, the heating channel includes a first channel and a second channel; the heater includes: an outer ring with a first notch; an inner ring with a second notch; a first channel between the outer ring and the inner ring; a second channel inside the inner ring; the second channel is connected to the air outlet; steam in the water tank assembly flows into the first channel through the first notch; and steam in the first channel flows into the second channel through the second notch.

[0043] The heater is provided with a first channel and a second channel. The first channel is connected to the water tank assembly. When the heating assembly is running, the water in the water tank assembly is heated into steam. The steam in the water tank assembly can flow into the first channel through the first notch. The steam in the first channel is heated. The heated steam flows into the second channel through the second notch. The steam is heated again in the second channel, so that the steam is heated into superheated steam in both the first and second channels.

[0044] By setting two sets of channels within the heater, steam can flow through the first and second channels sequentially, extending the steam's flow time within the heater. The longer the steam flows within the heater, the longer it is heated, thus effectively increasing the steam temperature. Through this method, the steam discharged into the cooking chamber can reach temperatures above 100°C, shortening the cooking time and accelerating cooking efficiency.

[0045] In some technical solutions, optionally, the first channel is distributed along the circumference of the inner ring; the base assembly further includes: a connecting rib, located in the first channel along the circumference of the inner ring, the second notch and the first notch are arranged adjacent to each other, and the connecting rib is spaced apart from the second notch and the first notch.

[0046] The inner ring has a first channel distributed circumferentially. To prolong the heating time of steam within the first channel, it is necessary to increase the steam flow path within the first channel. The maximum flow path of steam within the first channel is equal to the circumference of the first channel. To achieve this goal, a second notch is arranged adjacent to the first notch, and a connecting rib is provided between the second notch and the first notch.

[0047] Since the second notch and the first notch are adjacent, if no blocking component is installed between them, steam passing through the first notch will flow directly to the second notch. To avoid this, a connecting rib is installed between the second and first notches. This connecting rib prevents steam passing through the first notch from flowing directly to the second notch. After steam flows into the first channel, it needs to flow in the direction away from the connecting rib. After flowing a certain distance in the first channel, the steam passes through the second notch and flows into the second channel.

[0048] Since the second notch and the first notch are arranged adjacent to each other, the steam flow path in the first channel is basically equal to the circumference of the first channel due to the blocking effect of the connecting rib. This extends the steam flow path in the first channel as much as possible, which is beneficial to improving the heating effect of the steam.

[0049] In some technical solutions, optionally, the first notch is located at the top of the outer ring, and the juice tray covers the top of the first notch; and / or the second notch is located at the top of the inner ring, and the juice tray covers the top of the second notch.

[0050] The first notch is located at the top of the outer ring. The height of the first notch is relatively high, making it difficult for water in the water tank assembly to enter the heater through the first notch.

[0051] The second gap is located at the top of the inner ring, allowing steam to enter the inner ring from the top. When a steam cylinder is installed in the inner ring, the steam flowing in from the top of the inner ring needs to flow downwards to enter the steam cylinder, thus prolonging the flow time of the steam in the inner ring.

[0052] In some technical solutions, optionally, the drip tray is provided with a recessed portion, and the recessed portion is flared from the bottom to the top of the recessed portion.

[0053] The recessed section can collect the juice that drips onto the drip tray, preventing the juice from flowing into the heater through the vent.

[0054] The recess is flared, and therefore the sides of the recess are inclined, allowing steam to accumulate along the sidewalls of the recess towards the top of the heater.

[0055] In some technical solutions, the heating element may optionally include: a first heating element connected to the outer ring; and a second heating element connected to the inner ring.

[0056] The outer ring is equipped with a first heating element, which can heat the outer ring. The outer side of the outer ring is a water tank assembly, and the inner side of the outer ring is a first channel. Therefore, the outer ring can heat the water in the water tank assembly and also heat the first channel.

[0057] A second heating element is provided on the inner ring, which can heat the inner ring. The outer side of the inner ring is the first channel, and the inner side of the inner ring is the second channel. Therefore, the inner ring can heat both the first and second channels, which helps to increase the temperature of the steam and improve the cooking efficiency of the food.

[0058] In some technical solutions, the base assembly may optionally include: a steaming tray, disposed on the drip tray, the steaming tray having multiple air passage holes, an air passage cavity being formed between the steaming tray and the drip tray, the air passage cavity being connected to the air outlet and the air passage holes.

[0059] A venting cavity is formed between the steaming tray and the drip tray. That is, the steaming tray and the drip tray are not in contact with each other. The steam discharged from the vent flows into the venting cavity and is evenly distributed in the venting cavity. This allows the steam to flow evenly into the cooking cavity, improving the uniformity of temperature distribution in the cooking cavity and helping to improve the cooking effect of all parts of the food.

[0060] Secondly, this utility model proposes a cooking device, including a base assembly as described in the first aspect.

Detailed Implementation

[0071] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0072] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0073] The following reference Figures 1 to 6 This invention describes a base assembly and cooking device provided according to some embodiments of the present invention.

[0074] Combination Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments of this utility model, a base assembly 100 is proposed. The base assembly 100 is used in a cooking device, which has a cooking cavity 210. The base assembly 100 includes: a base 110, a water tank assembly 120, a heating assembly 130, and a drip tray 140. The water tank assembly 120 is disposed within the base 110, and the heating assembly 130 is disposed within the water tank assembly 120. The heating assembly 130 includes a heater 131 and a heating element 132. The heating element 132 is used to heat the water in the water tank assembly 120 and the heater 131. The heater 131 has a heating channel 133, and the top of the heating channel 133 has an opening 134. The heating channel 133 is connected to the water tank assembly 120. The drip tray 140 is disposed on the heater 131 and seals the opening 134. The drip tray 140 has a vent 141, and the steam flowing into the heating channel 133 flows to the cooking cavity 210 through the vent 141.

[0075] Heating element 130 is disposed inside water tank assembly 120. When heating element 132 is in operation, it heats the water in water tank assembly 120 to generate steam. Heating channel 133 is provided inside heater 131, and is connected to water tank assembly 120. Steam in water tank assembly 120 can flow into heating channel 133. Since heating element 132 can also heat heater 131, the steam flowing into heating channel 133 can be heated by heater 131, effectively increasing the steam temperature. The heated steam flows out of heating channel 133 and through air outlet 141 on drip tray 140 to cooking chamber 210, thereby heating the food in cooking chamber 210. Through this method, the steam discharged into cooking chamber 210 can reach temperatures above 100°C, shortening cooking time, accelerating cooking efficiency, and preventing nutrient loss by reducing cooking time.

[0076] The top of the heating channel 133 is provided with an opening 134, that is, the heating channel 133 in this solution is not a closed structure. Users can easily clean the inside of the heater 131, and can clean the scale and impurities inside the heater 131 in a timely manner to ensure the cleanliness of the inside of the heater 131.

[0077] When using the heating assembly 130, the drip tray 140 is placed on top of the heater 131. The drip tray 140 seals the opening 134 at the top of the heating channel 133, preventing external impurities from entering the heating channel 133. Furthermore, after steam flows into the heating channel 133 from the water tank assembly 120, the sealed top of the heating channel 133 allows the heated steam to flow out only through the outlet 141, preventing the heated steam from flowing back into the water tank assembly 120 and avoiding heat waste. Additionally, sealing the opening at the top of the heating channel 133 facilitates thorough heating of the steam by the heating element 132, increases the steam heating temperature, and reduces the impact of steam pressure on the stability of the drip tray 140.

[0078] Figure 1 , Figure 2 and Figure 3 The arrows in the diagram are used to indicate the direction of steam flow.

[0079] Combination Figure 2 and Figure 6 As shown, in some embodiments, optionally, the water tank assembly 120 includes a water tank body 121 and a water-blocking rib 122. The water-blocking rib 122 is located inside the water tank body 121 and divides the water tank body 121 into a water replenishment chamber 123 and a heating chamber 124. The water replenishment chamber 123 and the heating chamber 124 are connected. The heating assembly 130 is located inside the heating chamber 124.

[0080] The water-blocking rib 122 divides the interior of the water tank body 121 into a water supply chamber 123 and a heating chamber 124. The water-blocking rib 122 has openings that connect the water supply chamber 123 and the heating chamber 124. After a portion of the water in the heating chamber 124 is heated into steam, according to the principle of communicating vessels, the water supply chamber 123 can replenish water into the heating chamber 124, ensuring sufficient water volume and preventing dry burning within the heating chamber 124.

[0081] A small space (heating chamber 124) is defined inside the water tank body 121 by the water-proof rib 122, so that the water in the heating chamber 124 can be heated quickly, which is beneficial to improving the steam generation rate.

[0082] In some embodiments, optionally, the juice tray 140 is placed on the heater 131, and the water tank body 121 and the water-proof rib 122 are spaced apart from the juice tray 140; or, the juice tray 140 is placed on the heater 131 and the water-proof rib 122, the water tank body 121 and the juice tray 140 are spaced apart, and the water-proof rib 122 is fitted and sealed to the juice tray 140.

[0083] When the drip tray 140 is placed on the heater 131, the drip tray 140 contacts the top of the heater 131, thus sealing the opening 134 by its contact with the heater 131. To improve the sealing effect of the opening 134, in this design, the water tank body 121 and the water-proof rib 122 are spaced apart from the drip tray 140. That is, the drip tray 140 is only placed on the heater 131, and not on the water tank body 121 and the water-proof rib 122. Due to dimensional errors in the processing of each component, by leaving gaps between the water tank body 121 and the water-proof rib 122 and the drip tray 140, it is ensured that each component is within the dimensional tolerance range. The drip tray 140 can seal the top opening 134 of the heating channel 133, and the water tank body 121 and the water-proof rib 122 will not obstruct the downward placement of the drip tray 140, ensuring that the drip tray 140 can fit tightly against the heater 131.

[0084] Alternatively, the water tank body 121 and the juice receiving tray 140 can be arranged at an interval, with the juice receiving tray 140 placed on the heater 131 and the water-blocking rib 122, so that the juice receiving tray 140 not only seals the top opening 134 of the heater 131, but also seals the top of the heating chamber 124, preventing steam from flowing into the water replenishment chamber 123 from the top of the water-blocking rib 122.

[0085] In the above manner, no other parts are needed to connect the juice tray 140 and the heater 131, making it convenient to remove the juice tray 140 and clean the heater 131.

[0086] In some embodiments, the drip tray 140 and the heater 131 may be sealed by a sealing member.

[0087] A sealing component can be added between the juice tray 140 and the heater 131 to improve the sealing performance between them.

[0088] For example, the sealing component may be a sealing gasket or a sealant.

[0089] Combination Figure 2 and Figure 3 As shown, in some embodiments, optionally, the juice receiving tray 140 is provided with a limiting part 142, which cooperates with the heater 131 to limit the translation of the juice receiving tray 140 relative to the heater 131.

[0090] When the drip tray 140 is placed on the heater 131, the limiting part 142 on the drip tray 140 is located on one side of the heater 131. Normally, when the drip tray 140 is in use, the limiting part 142 will be attached to the heater 131. The heater 131 restricts the movement of the limiting part 142, thereby restricting the drip tray 140 from translating relative to the heater 131. This ensures that the drip tray 140 is not easily dislodged from its installation position, and prevents the air outlet 141 on the drip tray 140 from being misaligned with the outlet of the heating channel 133, ensuring that the steam in the heating channel 133 can be stably discharged through the air outlet 141.

[0091] In some embodiments, optionally, the limiting portion 142 protrudes from the surface of the juice receiving tray 140, and the heater 131 is located on the side of the limiting portion 142 opposite to the edge of the juice receiving tray 140.

[0092] The limiting part 142 has a protruding structure, and the heater 131 is located on the inner side of the limiting part 142. The protruding limiting part 142 restricts the juice receiving tray 140 from moving relative to the heater 131, ensuring that the juice receiving tray 140 is not easily dislodged from the installation position.

[0093] Combination Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the juice receiving tray 140 includes: a juice receiving tray body 143 and a boss 144. The boss 144 is disposed on the juice receiving tray body 143 and is higher than the top surface of the juice receiving tray body 143. An air outlet 141 is disposed on the boss 144. The boss 144 is disposed on the heater 131 and seals the opening 134.

[0094] The drip tray body 143 is placed on the heater 131. During the cooking process, the juice produced by the food will drip onto the drip tray body 143. The drip tray body 143 collects and holds the medium, making it convenient for users to clean up the juice from the food in one place, and preventing the juice from flowing into the water tank assembly 120 and contaminating the water in the water tank assembly 120.

[0095] In this design, a boss 144 is provided on the juice receiving tray body 143, protruding from the top surface of the juice receiving tray body 143. An air outlet 141 is located on the boss 144, therefore the air outlet 141 is also higher than the top surface of the juice receiving tray 140. When the amount of juice collected on the juice receiving tray body 143 increases, the juice on the juice receiving tray body 143 is less likely to flow into the air outlet 141, thereby preventing juice from flowing into the heater 131 through the air outlet 141, reducing the workload of cleaning the inside of the heater 131 for the user, and making it more convenient for the user.

[0096] In this design, the boss 144 is placed on the heater 131, and the boss 144 seals the opening 134.

[0097] Combination Figure 2 and Figure 3 As shown, in some embodiments, the projection surface is optionally set along the horizontal direction ( Figure 2 (The arrow at H1 points to) extending, the boss 144 and the heater 131 are projected onto the projection surface, and the projection of the heater 131 is located within the projection range of the boss 144.

[0098] Since the projection of heater 131 is located within the projection range of boss 144, the projection of boss 144 in the horizontal direction is greater than the projection of heater 131 in the horizontal direction, thus leaving a certain installation deviation margin for drip tray 140. The purpose is that when drip tray 140 is not placed in the center, boss 144 can still close the top opening 134 of heating channel 133.

[0099] In some embodiments, the boss 144 may be integrally formed on the juice tray body 143, or the boss 144 may be detachably connected to the juice tray body 143.

[0100] The boss 144 can be integrally formed with the juice tray body 143. A part of the juice tray body 143 is bent away from the heater 131, thereby forming the boss 144 on the juice tray body 143. The boss 144 is not easily separated from the juice tray body 143, ensuring the structural stability of the juice tray 140.

[0101] A separate component can be used as the boss 144, which is locked onto the juice tray body 143. When it is necessary to clean the inside of the heater 131, the boss 144 can be removed from the juice tray body 143 to open the opening 134 on the top of the heater 131. During this process, it is not necessary to remove the juice tray 140, which is convenient for the user.

[0102] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, the juice tray body 143 includes: a bottom wall 145 and a side wall 146, the side wall 146 being connected to the edge of the bottom wall 145, at least a portion of the side wall 146 being higher than the bottom wall 145, and the air outlet 141 being higher than the top of the side wall 146.

[0103] The bottom wall 145 is provided with a side wall 146 at its edge. At least a portion of the side wall 146 is higher than the bottom wall 145, so that the bottom wall 145 and the side wall 146 enclose a receiving space, and the juice collected on the juice tray 140 is not likely to flow to the outside of the juice tray body 143.

[0104] As the amount of juice collected on the juice receiving tray 143 increases, the liquid level on the juice receiving tray 143 gradually rises. In this design, the vent 141 is set higher than the top of the side wall 146. Even if the juice receiving tray 143 is full of water, the vent 141 is still higher than the liquid level on the juice receiving tray 143, ensuring that the medium will not enter the heater 131 through the vent 141.

[0105] The drip tray 140 has a bottom wall 145 and a side wall 146 extending upward along the outer periphery of the bottom wall 145. An upward-facing boss 144 is also provided in the middle of the bottom wall 145. The drip tray 140 is made of stainless steel. In this cooking device with the drip tray 140, the drip tray 140 is placed on a heater 131. The boss 144 of the drip tray 140 contacts and seals the top of the heater 131, while the drip tray 140 does not contact the water tank assembly 120. Gaps are left between the drip tray 140 and the water tank assembly 120's water-resistant ribs 122, as well as around the periphery of the water tank assembly 120, to ensure that all components are within dimensional tolerances. The boss 144 of the drip tray 140 can seal the top of the heater 131.

[0106] like Figure 2 As shown, in some embodiments, optionally, the base assembly 100 further includes a steam cylinder 150, which is connected to the drip tray 140. The first end of the steam cylinder 150 is connected to the air outlet 141, and the second end of the steam cylinder 150 extends into the heating channel 133. The steam in the heating channel 133 flows through the steam cylinder 150 to the air outlet 141.

[0107] A steam cylinder 150 is provided inside the heater 131. The steam entering the heating channel 133 needs to pass through the steam cylinder 150 before flowing to the outlet 141.

[0108] By incorporating a heat-conducting cylinder within the heater 131, the steam flowing into the heating channel 133 does not directly flow to the outlet 141. Instead, it first flows into the heat-conducting cylinder, extending the steam's flow time within the heater 131. The longer the steam flows within the heater 131, the longer it is reheated, effectively increasing its temperature. Through this method, the steam discharged into the cooking chamber 210 can reach temperatures above 100°C, shortening the cooking time and accelerating cooking efficiency.

[0109] In some embodiments, the first end of the steam cylinder 150 is optionally integrally formed with the juice receiving tray 140. Alternatively, the first end of the steam cylinder 150 is sealed to the juice receiving tray 140.

[0110] One end of the steam cylinder 150 is connected to the drip tray 140, making the steam cylinder 150 and the drip tray 140 an integral structure. This prevents the steam cylinder 150 from easily separating from the drip tray 140, ensuring the structural stability of the drip tray 140. Furthermore, since the steam cylinder 150 is integrally formed into the drip tray 140, no other sealing structure is needed between the steam cylinder 150 and the drip tray 140, ensuring a tight seal between them and preventing steam from escaping through gaps. This ensures that the steam in the heating channel 133 passes through the steam cylinder 150.

[0111] The steam cylinder 150 and the juice tray 140 can also be designed separately, but the steam cylinder 150 and the juice tray 140 need to be sealed to prevent steam from overflowing from the gap between the steam cylinder 150 and the juice tray 140.

[0112] like Figure 2 As shown, in some embodiments, optionally, the second end of the steam cylinder 150 is spaced apart from the bottom wall 145 of the heating channel 133, and the steam in the heating channel 133 flows into the steam cylinder 150 through the second end of the steam cylinder 150.

[0113] The second end of the steam cylinder 150 is the bottom of the steam cylinder 150. An opening is provided at the bottom of the steam cylinder 150 so that the steam in the heating channel 133 flows into the steam cylinder 150 through the bottom of the steam cylinder 150. The steam in the heating channel 133 first flows downward to the bottom of the steam cylinder 150, and then flows upward in the steam cylinder 150. In this way, the flow path of the steam in the heater 131 is further extended.

[0114] Combination Figure 2 and Figure 5As shown, in some embodiments, optionally, the heating channel 133 includes a first channel 135 and a second channel 136. The heater 131 includes an outer ring 138 and an inner ring 137. The outer ring 138 is provided with a first notch 1371, and the inner ring 137 is provided with a second notch 1381. The first channel 135 is provided between the outer ring 138 and the inner ring 137. The second channel 136 is provided inside the inner ring 137. The second channel 136 is connected to the air outlet 141. Steam in the water tank assembly 120 flows into the first channel 135 through the first notch 1371, and steam in the first channel 135 flows into the second channel 136 through the second notch 1381.

[0115] The heater 131 is provided with a first channel 135 and a second channel 136. The first channel 135 is connected to the water tank assembly 120. When the heating assembly 130 is running, the water in the water tank assembly 120 is heated into steam. The steam in the water tank assembly 120 can flow into the first channel 135 through the first notch 1371. The steam in the first channel 135 is heated. The heated steam flows into the second channel 136 through the second notch 1381. The steam is reheated in the second channel 136, so that the steam is heated into superheated steam in the first channel 135 and the second channel 136.

[0116] By providing two sets of channels within the heater 131, steam can flow sequentially through the first channel 135 and the second channel 136, extending the steam's flow time within the heater 131. The longer the steam flows within the heater 131, the longer it is heated, thus effectively increasing its temperature. Through this method, the steam discharged into the cooking chamber 210 can reach temperatures above 100°C, shortening the cooking time and accelerating cooking efficiency.

[0117] In some embodiments, optionally, the first channel 135 is circumferentially aligned with the inner ring 137. Figure 5 The distribution is indicated by the arrow at H2. The base assembly 100 also includes a connecting rib 170, which is located within the first channel 135 and along the circumference of the inner ring 137. The second notch 1381 and the first notch 1371 are arranged adjacent to each other, and the connecting rib 170 is spaced apart from the second notch 1381 and the first notch 1371.

[0118] The inner ring 137 has a first channel 135 distributed circumferentially. In order to prolong the heating time of steam in the first channel 135, it is necessary to increase the flow path of steam in the first channel 135. The maximum flow path of steam in the first channel 135 is the circumference of the first channel 135. To achieve the above objective, the second notch 1381 and the first notch 1371 are arranged adjacent to each other, and a connecting rib 170 is provided between the second notch 1381 and the first notch 1371.

[0119] Since the second gap 1381 and the first gap 1371 are arranged adjacent to each other, if no blocking component is provided between the second gap 1381 and the first gap 1371, the steam passing through the first gap 1371 will flow directly to the second gap 1381. To avoid this situation, a connecting rib 170 is provided between the second gap 1381 and the first gap 1371. The connecting rib 170 prevents the steam passing through the first gap 1371 from flowing directly to the second gap. After the steam flows into the first channel 135, the steam needs to flow in the direction away from the connecting rib 170 within the first channel 135. After flowing a certain distance within the first channel 135, the steam passes through the second gap 1381 and flows into the second channel 136 through the second gap 1381.

[0120] Since the second notch 1381 and the first notch 1371 are arranged adjacent to each other, under the blocking effect of the connecting rib 170, the flow path of steam in the first channel 135 is basically equal to the circumference of the first channel 135, which extends the flow path of steam in the first channel 135 as much as possible and is conducive to improving the heating effect of steam.

[0121] Combination Figure 2 and Figure 5 As shown, in some embodiments, optionally, the first notch 1371 is located at the top of the outer ring 138, and the juice tray 140 covers the top of the first notch 1371; and / or the second notch 1381 is located at the top of the inner ring 137, and the juice tray 140 covers the top of the second notch 1381.

[0122] The first notch 1371 is located at the top of the outer ring 138. The height of the first notch 1371 is relatively high, so the water in the water tank assembly 120 is not easy to enter the heater 131 through the first notch 1371.

[0123] The second gap 1381 is provided at the top of the inner ring 137, so that steam enters the interior of the inner ring 137 from the top of the inner ring 137. When the steam cylinder 150 is provided in the inner ring 137, the steam flowing in from the top of the inner ring 137 needs to flow downward so that it can flow into the steam cylinder 150, thus prolonging the flow time of the steam in the inner ring 137.

[0124] In some embodiments, the drip tray 140 may optionally have a recess 147, which is flared in the direction from the bottom to the top of the recess 147.

[0125] The recess 147 can collect the juice that drips onto the juice tray 140, preventing the juice from flowing into the heater 131 through the air outlet 141.

[0126] The recess 147 is flared, so the side of the recess 147 is inclined, which allows steam to accumulate along the side wall of the recess 147 to the top of the heater 131.

[0127] In some embodiments, optionally, a third channel 151 is provided inside the steam cylinder 150, and the minimum cross-sectional area S1 of the third channel 151 satisfies 50 mm. 2 ≤S1≤200mm 2 The minimum cross-sectional area S2 of the second channel 136 between the inner ring 137 and the steam cylinder 150 satisfies 50 mm. 2 ≤S2≤200mm 2 .

[0128] Steam in the second channel 136 flows into the third channel 151 and then into the cooking chamber 210. In this design, the minimum cross-sectional area of ​​the portion of the second channel 136 and the third channel 151 between the steam cylinder 150 and the inner ring 137 is limited to 50 mm². 2 Up to 200mm 2 The purpose of this is to prevent steam from not being discharged in time and to prevent pressure from forming in the second channel 136 and the third channel 151.

[0129] For example, the minimum cross-sectional area of ​​the third channel 151 is 50 mm. 2 60mm 2 Or 70mm 2 The minimum cross-sectional area of ​​a portion of the second channel 136 between the steam cylinder 150 and the inner ring 137 is 50 mm. 2 60mm 2 Or 70mm 2 .

[0130] like Figure 2 As shown, in some embodiments, optionally, the heating element 132 includes: a first heating element 1321 and a second heating element 1322, wherein the first heating element 1321 is connected to the outer ring 138 and the second heating element 1322 is connected to the inner ring 137.

[0131] A first heating element 1321 is provided on the outer ring 138. The first heating element 1321 can heat the outer ring 138. The outer side of the outer ring 138 is the water tank assembly 120, and the inner side of the outer ring 138 is the first channel 135. Therefore, the outer ring 138 can heat the water in the water tank assembly 120 and also heat the first channel 135.

[0132] A second heating element 1322 is provided on the inner ring 137, which can heat the inner ring 137. The outer side of the inner ring 137 is the first channel 135, and the inner side of the inner ring 137 is the second channel 136. Therefore, the inner ring 137 can heat both the first channel 135 and the second channel 136, which helps to increase the temperature of the steam and improve the cooking efficiency of the food.

[0133] The drip tray 140 has a vent 141 on its boss 144. A steam cylinder 150 is connected to the bottom of the vent 141 and extends downward from the boss 144, with the downward extension located inside the inner ring 137 of the heater 131. The vent 141 of the steam cylinder 150 is higher than the inner bottom wall 139 of the heater 131, leaving a gap to allow steam to pass through. The vent 141 of the steam cylinder 150 is higher than the side wall 146 of the drip tray 140 to prevent juice from the drip tray 140 from entering the heater 131 through the vent 141.

[0134] A cooking device with a drip tray 140 includes a heater 131 disposed between the drip tray 140 and a water tank assembly 120. The heater 131 has an inner ring 137 and an outer ring 138 connected by an inner bottom wall 139. A second heating element 1322 and a first heating element 1321 are correspondingly disposed below the top ends of the inner ring 137 and the outer ring 138. A second notch 1381 and a first notch 1371 are respectively provided on the inner ring 137 and the outer ring 138. The drip tray 140 closes the top ends of the inner ring 137 and the outer ring 138, forming a first channel 135 between the outer ring 138 and the inner ring 137 of the heater 131. Steam flows from the first notch 1371 of the outer ring 138 along the first channel 135 to the second notch 1381 of the inner ring 137, and is heated by the surface between the inner ring 137 and the outer ring 138 during this process. A second channel 136 is formed between the inner ring 137 and the steam cylinder 150. Steam enters the second channel 136 from the second notch 1381. The inner ring 137 simultaneously heats the steam in the second channel 136 and the steam cylinder 150. The steam flows downward along the second channel 136, then flows upward along the inner surface of the steam cylinder 150 to the cooking chamber 210 after passing over the bottom of the steam cylinder 150. During this process, the steam is further heated into superheated steam.

[0135] For example, the first heating element 1321 and the second heating element 1322 can be heating tubes.

[0136] like Figure 2As shown, in some embodiments, optionally, the base assembly 100 further includes: a steaming tray 160, which is disposed on the drip tray 140. The steaming tray 160 is provided with a plurality of air passage holes 161. An air passage cavity 162 is formed between the steaming tray 160 and the drip tray 140. The air passage cavity 162 connects the air outlet 141 and the air passage holes 161.

[0137] A venting cavity 162 is formed between the steaming tray 160 and the drip tray 140. That is, the steaming tray 160 and the drip tray 140 are not in contact with each other. The steam discharged from the steam outlet 141 flows into the venting cavity 162 and is evenly distributed in the venting cavity 162, so that the steam can flow evenly into the cooking cavity 210, improving the uniformity of temperature distribution in the cooking cavity 210, which is beneficial to improving the cooking effect of the ingredients in all parts.

[0138] In an embodiment of this utility model, a cooking device is proposed, including a base assembly 100 as described in any of the above embodiments, and can achieve the same technical effect, which will not be repeated here.

[0139] Heating element 130 is disposed inside water tank assembly 120. When heating element 132 is in operation, it heats the water in water tank assembly 120 to generate steam. Heating channel 133 is provided inside heater 131, and is connected to water tank assembly 120. Steam in water tank assembly 120 can flow into heating channel 133. Since heating element 132 can also heat heater 131, the steam flowing into heating channel 133 can be heated by heater 131, effectively increasing the steam temperature. The heated steam flows out of heating channel 133 and through air outlet 141 on drip tray 140 to cooking chamber 210, thereby heating the food in cooking chamber 210. Through this method, the steam discharged into cooking chamber 210 can reach temperatures above 100°C, shortening cooking time, accelerating cooking efficiency, and preventing nutrient loss by reducing cooking time.

[0140] The top of the heating channel 133 is provided with an opening 134, that is, the heating channel 133 in this solution is not a closed structure. Users can easily clean the inside of the heater 131, and can clean the scale and impurities inside the heater 131 in a timely manner to ensure the cleanliness of the inside of the heater 131.

[0141] When using the heating assembly 130, the drip tray 140 is placed on top of the heater 131. The drip tray 140 can seal the opening 134 at the top of the heating channel 133, preventing external impurities from entering the heating channel 133. Moreover, after steam flows into the heating channel 133 from the water tank assembly 120, the heated steam can only flow out through the vent 141 because the top of the heating channel 133 is sealed, preventing the heated steam from flowing back into the water tank assembly 120 and avoiding waste of heat.

[0142] In this embodiment, the drip tray 140 rests on the heater 131, and the drip tray 140 is spaced apart from the water tank assembly 120, ensuring that the drip tray 140 can stably seal the top of the heater 131. In other embodiments, the drip tray 140 and the heater 131 can be sealed by a sealing component.

[0143] like Figure 1 As shown, the cooking device also includes a housing 200, which is fastened to the base 110, and a cooking cavity 210 is provided inside the housing 200. The housing 200 can be a lid structure, or the housing 200 can include a steamer and a lid, thereby forming a multi-layer cavity structure inside the housing 200.

[0144] For example, the cooking equipment can be an electric steamer, a cooking pot, etc.

The terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium.
