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] Cooking equipment generates a large amount of high-temperature steam during the cooking process. Since the temperature inside the kitchen cabinets is relatively low, when the high-temperature steam encounters the cabinets, condensation will form on the cabinets. Users need to clean the condensation on the cabinets, which causes inconvenience to users when using the cooking equipment. 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, in a first aspect, the present invention proposes a base assembly for a cooking device having a cooking chamber. The base assembly includes: a base; a water tank located inside the base, the water tank having a steam supply port, a steam recovery port, and a steam exhaust port; a water-separating rib located inside the water tank, the water-separating rib dividing the water tank into an evaporation chamber and a recovery chamber, the evaporation chamber and the recovery chamber being used for water storage, the steam supply port being connected to the evaporation chamber, and the steam recovery port and the steam exhaust port being connected to the recovery chamber; and a steam generating assembly located inside the evaporation chamber, the steam generated by the steam generating assembly flowing to the cooking chamber through the steam supply port, and the steam returning to the recovery chamber being discharged outward through the steam exhaust port.

[0005] The water tank is located on the base and is used to store water. The steam generator is located inside the water tank and can heat the water in the water tank to generate steam. The steam generated by the steam generator can flow to the cooking cavity through the steam supply port, thereby heating the food in the cooking cavity.

[0006] A water-blocking rib is installed inside the water tank, dividing the internal space into an evaporation chamber and a recovery chamber. The steam generating component is installed in the evaporation chamber, which is connected to the steam supply port. As the amount of steam in the cooking chamber gradually increases, the steam can flow back into the water tank. A steam recovery port is provided on the water tank, connected to the recovery chamber, through which steam from the cooking chamber flows into the recovery chamber. A steam vent is also provided on the water tank, through which the steam flowing back into the recovery chamber can be discharged.

[0007] Because the water tank contains water, the steam flowing into the recovery chamber can exchange heat with the water, thereby lowering the steam temperature. The cooled steam in the recovery chamber can then be discharged from the cooking equipment. Since the discharged steam is at a lower temperature, users around the cooking equipment are less likely to be scalded, improving user safety during cooking. Furthermore, the heat exchange between steam and water reduces the amount of steam emitted to the outside. Also, because the discharged steam is at a lower temperature, the temperature difference between the low-temperature steam and the cabinet is smaller, making it less likely for condensation to form on the cabinet, reducing the amount of work required to clean condensation and providing greater convenience for users.

[0008] The steam generating component is installed inside the evaporation chamber. The steam generating component mainly heats the water in the evaporation chamber. When the steam in the cooking chamber flows back into the recovery chamber, the steam may carry food juices, odors, etc. Since the water-blocking rib can separate the evaporation chamber and the recovery chamber, the steam in the recovery chamber is less likely to enter the evaporation chamber. This reduces the probability that food juices and odors will come into contact with the water in the evaporation chamber, and reduces the probability of affecting the water quality in the evaporation chamber.

[0009] 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:

[0010] In some technical solutions, the steam recovery port and the steam exhaust port may optionally be located on adjacent sides of the water tank; or the steam recovery port and the steam exhaust port may be located on opposite sides of the water tank; or the steam recovery port and the steam exhaust port may be located on diagonal sides of the water tank.

[0011] After the steam flows back into the recovery chamber, the longer the steam flows in the recovery chamber, the longer the time for heat exchange between the steam and water is, which can improve the cooling effect of the steam.

[0012] The steam recovery port and the steam exhaust port can be located on adjacent sides of the water tank, or on opposite sides of the water tank, or on diagonally opposite sides of the water tank. Since the steam recovery port and the steam exhaust port are not located on the same side of the water tank, the steam exhaust port can be moved away from the steam recovery port to prolong the time it takes for steam to flow from the steam recovery port to the steam exhaust port.

[0013] In some technical solutions, optionally, the perimeter of the water tank is set as C1, and the distance between the steam recovery port and the exhaust port along the circumference of the water tank is C2, where C2≥(1 / 3)×C1.

[0014] Along the circumference of the water tank, the distance between the steam recovery port and the steam exhaust port should be at least one-third of the circumference of the water tank. Under the above conditions, a larger distance between the steam recovery port and the steam exhaust port can increase the time for steam to flow from the steam recovery port to the steam exhaust port, thereby improving the heat exchange effect between steam and water.

[0015] In some technical solutions, optionally, the water tank is equipped with a maximum liquid level line, and the vent is higher than the maximum liquid level line.

[0016] The water tank is equipped with a maximum liquid level line, which serves as a guide during water filling, reminding users not to exceed the maximum liquid level. This design limits the vent outlet to be above the maximum liquid level line, preventing water from entering the vent outlet and avoiding blockage. This ensures a stable discharge of steam from the recovery chamber through the vent outlet.

[0017] In some technical solutions, optionally, the height difference between the exhaust port and the highest liquid level line is H1, where H1 ≥ 10 mm.

[0018] There is a height difference between the vent and the highest liquid level line, and the vent is located at least 10mm above the plane where the highest liquid level line of the water tank is located. When the water tank shakes, the liquid level inside the tank will also fluctuate. Maintaining a certain distance between the vent and the highest liquid level line can further prevent water from entering the vent.

[0019] In some technical solutions, optionally, the water-proof rib is provided with water passage holes, and the evaporation chamber and the recovery chamber are connected through the water passage holes.

[0020] The steam generating component heats the water in the evaporation chamber to generate steam. During the steam generation process, the water in the evaporation chamber will decrease. Since the evaporation chamber and the recovery chamber are connected through a water passage, the water in the recovery chamber can be replenished into the evaporation chamber, thus preventing the water in the recovery chamber from burning dry.

[0021] When steam from the cooking chamber flows back into the recovery chamber, it exchanges heat with the water in the recovery chamber, raising the water temperature. When the water from the recovery chamber is replenished into the evaporation chamber, its temperature is not too low, allowing the steam generator to quickly heat the water and produce steam. Therefore, by exchanging heat between the water and steam in the recovery chamber, heat recovery from the steam is achieved. A portion of the steam is condensed and recovered, while the remaining steam is discharged through the exhaust port. The steam generator can heat water to a certain temperature, allowing for faster cooking, improved degreasing of food, and reduced steam emissions. Furthermore, the rapid heating of water by the steam generator contributes to energy savings and extends the water tank's operating time.

[0022] In some technical solutions, optionally, the water tank includes: a water tank body, a steam supply port located on a drip tray, and a recessed portion on the top edge of the water tank body; a drip tray overlapping the top edge of the water tank body, and a steam recovery port forming between the drip tray and the recessed portion.

[0023] The water tank body is used to store water, and the drip tray is set on the top of the water tank body. An inner cavity is formed between the drip tray and the water tank body. When the steam generating component is running, the water in the water tank is heated and steam is generated in the water tank. After the steam is generated, the steam is discharged into the cooking chamber through the steam supply port on the drip tray. Since the cooking chamber is located above the drip tray, the steam discharged from the steam supply port directly enters the cooking chamber, thereby ensuring that the high-temperature steam can quickly heat the food.

[0024] The cooking cavity is located above the drip tray. During cooking, the drip tray collects and holds the juices flowing from the food, allowing users to easily manage these juices and improving the usability of the cooking equipment. Using the drip tray as the enclosure for the inner cavity eliminates the need for additional components that mate with the water tank, simplifying the structure of the cooking equipment.

[0025] The drip tray overlaps the top edge of the water tank body, and a recess is provided on the top edge. At the position of the recess, the drip tray does not contact the top edge of the water tank, thus forming a steam recovery port between the drip tray and the water tank body. Steam can flow into the recovery chamber through the gap between the drip tray and the water tank body.

[0026] In some technical solutions, the water tank may optionally include: a first limiting rib, located at the top of the water tank body, the first limiting rib being used to restrict the juice receiving tray from translating relative to the water tank body.

[0027] A first limiting rib is provided on the top of the water tank body. The first limiting rib plays a limiting role in the drip tray, preventing the drip tray from moving around on the top of the water tank body and ensuring the stability of the drip tray.

[0028] In some technical solutions, the first limiting rib may optionally be higher than the edge of the juice receiving tray, or the first limiting rib may be flush with the edge of the juice receiving tray.

[0029] The first limiting rib needs to have a certain height in order to effectively limit the juice receiving tray. In this solution, the first limiting rib is limited to being higher than the juice receiving tray, or the first limiting rib is flush with the juice receiving tray, so as to prevent the juice receiving tray from tilting and moving, and further improve the placement stability of the juice receiving tray.

[0030] In some technical solutions, the water tank may optionally include: a second limiting rib, located at the top of the water tank body, a first limiting rib located between the drip tray and the second limiting rib, and a gap between the first limiting rib and the second limiting rib for placing the steamer or pot lid of the cooking equipment.

[0031] The top of the water tank body is also provided with a second limiting rib, which is located outside the first limiting rib. The first limiting rib and the second limiting rib are spaced apart. The bottom of the steamer or pot lid can extend between the first limiting rib and the second limiting rib, thereby limiting the position of the steamer or pot lid.

[0032] In some technical solutions, optionally, the height of the second limiting rib is H2, where H2 ≥ 5mm.

[0033] The height of the second limiting rib should not be less than 5mm. Increasing the corresponding area of ​​the second limiting rib and the steamer in the height direction, or increasing the corresponding area of ​​the second limiting rib and the pot lid in the height direction, is beneficial to improving the limiting effect of the second limiting rib on the steamer or pot lid.

[0034] In some technical solutions, the second limiting rib may optionally include an annular limiting rib, which is distributed along the circumference of the water tank.

[0035] In this design, the second limiting rib is a ring structure. When the steamer or pot lid extends between the first and second limiting ribs, the groove between the side wall of the steamer or pot lid and the second limiting rib stores the water condensed by the steam, thereby forming a seal and preventing steam leakage.

[0036] In some technical solutions, the water tank may optionally include: a water tank body; a drip tray, which overlaps the top edge of the water tank body, and a steam supply port and a steam recovery port are located on the drip tray.

[0037] The drip tray is placed on the water tank body. Holes can be directly drilled in the drip tray and used as steam recovery ports. No changes to the structure of the water tank body are required, reducing the processing difficulty of the cooking equipment.

[0038] In some technical solutions, the base assembly may optionally include a temperature sensor connected to the water tank, with at least a portion of the temperature sensor extending into the steam recovery port.

[0039] A temperature sensor is installed at the steam recovery port to detect the steam temperature inside the cooking chamber. Typically, after the cooking chamber is filled with steam, the steam flows towards the steam recovery port. Therefore, placing the temperature sensor at the steam recovery port allows for accurate measurement of the temperature inside the cooking chamber.

[0040] In some technical solutions, optionally, the vent is located on the side of the water tank, and the water tank is provided with a connecting pipe that is connected to the vent, with one part of the connecting pipe being bent relative to the other part.

[0041] When the vent is located on the side of the water tank, if steam is discharged directly from the vent, it will flow directly towards the wall, easily causing condensation to form on the wall. This design restricts the steam flow from the vent to the connecting pipe, which has a bend in its structure, preventing the steam from flowing directly towards the wall. This avoids condensation formation on the wall and reduces the amount of cleaning work required by the user.

[0042] In some technical solutions, optionally, the steam generating assembly includes: a heater located inside the evaporation chamber, the heater including an inner ring, an outer ring and a heating element, a first air inlet channel provided between the inner ring and the outer ring, the first air inlet channel being connected to the evaporation chamber, a second air inlet channel provided in the inner ring, the second air inlet channel being connected to the first air inlet channel, a steam supply port being connected to the second air inlet channel, and the heating element being used to heat the inner ring and the outer ring.

[0043] The heater is installed inside the evaporation chamber. The heater has a first air inlet channel and a second air inlet channel. The first air inlet channel is connected to the evaporation chamber. When the heater is running, it can heat the evaporation chamber. When the water in the evaporation chamber is heated into steam, the steam in the evaporation chamber can flow into the first air inlet channel. The heater can also heat the first air inlet channel and the second air inlet channel, so that the steam flowing into the first air inlet channel can be reheated, thereby being heated into superheated steam in the first air inlet channel and the second air inlet channel.

[0044] The first and second air intake channels are connected, allowing steam flowing into the first channel to continue flowing into the second. By providing two sets of air intake channels within the heater, steam can flow sequentially through both channels, extending its flow time within the heater. The longer the steam flows, the longer it is reheated, effectively increasing its temperature. This allows the steam discharged into the cooking chamber to reach temperatures above 100°C, shortening cooking time, accelerating cooking efficiency, and preventing nutrient loss.

[0045] In some technical solutions, optionally, the inner ring has a first connecting port on its side and the outer ring has a second connecting port on its side. The first air intake channel and the second air intake channel are connected through the first connecting port, and the evaporation chamber and the first air intake channel are connected through the second connecting port. At least a portion of the first connecting port is staggered from the second connecting port.

[0046] Because at least a portion of the first connecting port is misaligned with the second connecting port, some steam will not flow directly to the first connecting port, allowing some steam to flow circumferentially along the inner ring, thereby extending the steam flow time in the first air intake channel and further improving the steam heating time.

[0047] In some technical solutions, optionally, the first air intake channel is distributed circumferentially along the inner ring; the base assembly further includes: a connecting rib located inside the first air intake channel, the connecting rib being located between the first connecting port and the second connecting port.

[0048] After steam flows into the first intake channel, some steam flows clockwise relative to the inner ring, while other steam flows counterclockwise relative to the inner ring. To restrict the steam to flow in only one direction, a connecting rib is provided between the first and second connecting ports. The connecting rib restricts the steam flow, allowing it to flow only in the direction away from the connecting rib. In this way, the steam flows in a predetermined direction. For example, in this predetermined direction, the path between the second and first connecting ports can be set to be longer, thereby increasing the steam flow time in the first intake channel and thus increasing the secondary heating time of the steam.

[0049] In some technical solutions, optionally, the first connecting port and the second connecting port are arranged adjacent to each other along the circumference of the inner ring, and the connecting ribs are spaced apart from the first connecting port and the second connecting port.

[0050] The inner ring has a first intake channel distributed circumferentially. To prolong the heating time of steam within the first intake channel, the steam flow path within it needs to be increased. The maximum flow path of steam within the first intake channel is equal to the circumference of the first intake channel. To achieve this, the second connecting port and the first connecting port are arranged adjacent to each other, with a connecting rib between them. Since the second and first connecting ports are adjacent, if no blocking component is provided between them, steam passing through the second connecting port will flow directly to the first connecting port. To avoid this, a connecting rib is provided between the second and first connecting ports to prevent steam from flowing directly from the second connecting port to the first connecting port. After entering the first intake channel, the steam needs to flow in the direction away from the connecting rib. After flowing a certain distance within the first intake channel, the steam passes through the first connecting port and then flows into the second intake channel.

[0051] Since the second connecting port and the first connecting port are arranged adjacent to each other, the steam flow path in the first air intake channel is basically equal to the circumference of the first air intake channel due to the blocking effect of the connecting rib. This extends the steam flow path in the first air intake channel as much as possible, which is beneficial to improving the heating effect of the steam.

[0052] In some embodiments, optionally, a first air inlet channel is distributed circumferentially on the inner ring. After steam flows into the first air inlet channel, the steam flows circumferentially along the inner ring. The second connecting port and the first connecting port are distributed on opposite sides of the inner ring. Therefore, the flow path of steam in the first air inlet channel is half the circumference of the first air inlet channel. With the above arrangement, the first connecting port can be moved away from the second connecting port, extending the flow path of steam in the first air inlet channel as much as possible and improving the heating effect of steam.

[0053] In one possible application, steam flows into the first intake channel through the second connector. Within the first intake channel, the steam splits into two streams, which flow along opposite sides of the inner ring towards the first connector, eventually converging at the first connector. The two streams can be heated simultaneously within the first intake channel, which helps increase the amount of steam heated per unit time and improves the steam heating efficiency.

[0054] In some technical solutions, the base assembly may optionally include: a steam cylinder connected to the water tank and located in the second air inlet channel; the steam cylinder has an exhaust channel; the steam supply port and the second air inlet channel are connected through the bottom of the exhaust channel; and the heating element is also used to heat the steam cylinder.

[0055] A steam cylinder is installed inside the second air inlet channel, and an exhaust channel is installed inside the steam cylinder. Because the heater can also heat the steam cylinder, the surface temperature of the steam cylinder and the temperature of the exhaust channel inside the steam cylinder are both high. After the steam flows into the second air inlet channel, the steam flows through the steam cylinder. Due to the high surface temperature of the steam cylinder, the steam cylinder can continue to heat the steam. When the steam flows into the exhaust channel, the exhaust channel further heats the steam.

[0056] In this design, the first connecting port is higher than the bottom of the exhaust channel. The steam in the first intake channel flows into the second intake channel through the first connecting port. Since the first connecting port is higher than the bottom of the exhaust channel, the steam flowing into the second intake channel diffuses from top to bottom. When the steam flows to the bottom of the steam cylinder, the steam can flow into the exhaust channel.

[0057] When steam flows naturally, the higher-temperature steam tends to rise. This downward diffusion, which is opposite to the natural flow direction of steam, prolongs the steam's circulation time in the second intake channel, increases the heat exchange of the steam, and as the steam flows towards the exhaust channel, it continuously absorbs heat from the second intake channel and the surface heat of the steam cylinder, thus heating the steam into superheated steam and improving the heating efficiency of the food.

[0058] Secondly, this utility model proposes a cooking device, including a base assembly as described in any of the technical solutions in the first aspect.

[0059] In some technical solutions, the cooking equipment may optionally include a steamer and a pot lid, wherein there is a gap between the first and second limiting ribs in the base assembly for placing the steamer or pot lid.

[0060] The top of the water tank body is provided with a first limiting rib and a second limiting rib. The second limiting rib is located outside the first limiting rib, and the first limiting rib and the second limiting rib are spaced apart. The bottom of the steamer or pot lid can extend out between the first limiting rib and the second limiting rib, thereby limiting the position of the steamer or pot lid.

[0061] In this design, the second limiting rib is a ring structure. When the steamer or pot lid extends between the first and second limiting ribs, the groove between the side wall of the steamer or pot lid and the second limiting rib stores the water condensed by the steam, thereby forming a seal and preventing steam leakage.

[0062] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

Detailed Implementation

[0073] 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.

[0074] 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.

[0075] The following reference Figures 1 to 7 This invention describes a base assembly and cooking device provided according to some embodiments of the present invention.

[0076] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As 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 200. The base assembly 100 includes: a base 110, a water tank 120, a water-blocking rib 130, and a steam generating assembly 140. The water tank 120 is located inside the base 110 and is provided with a steam supply port 121, a steam recovery port 122, and a steam exhaust port 123. The water-blocking rib 130 is located inside the water tank 120 and divides the water tank 120 into an evaporation cavity 124 and a recovery cavity 125. The evaporation cavity 124 and the recovery cavity 125 are used for water storage. The steam supply port 121 is connected to the evaporation cavity 124, and the steam recovery port 122 and the steam exhaust port 123 are both connected to the recovery cavity 125. The steam generating assembly 140 is located in the evaporation chamber 124. The steam generated by the steam generating assembly 140 flows to the cooking chamber 200 through the steam supply port 121, and the steam that flows back to the recovery chamber 125 is discharged to the outside through the exhaust port 123.

[0077] A water tank 120 is mounted on a base 110 and is used to store water. A steam generating component 140 is mounted inside the water tank 120 and can heat the water in the water tank 120 to generate steam. The steam generated by the steam generating component 140 can flow to the cooking chamber 200 through the steam supply port 121, thereby heating the food in the cooking chamber 200.

[0078] Figure 1 The middle arrow is used to indicate the direction of steam flow.

[0079] A water-blocking rib 130 is installed inside the water tank 120, dividing the internal space of the water tank 120 into an evaporation chamber 124 and a recovery chamber 125. A steam generating assembly 140 is installed inside the evaporation chamber 124, which is connected to the steam supply port 121. As the amount of steam in the cooking chamber 200 gradually increases, the steam in the cooking chamber 200 can flow back into the water tank 120. A steam recovery port 122 is provided on the water tank 120, which is connected to the recovery chamber 125. The steam in the cooking chamber 200 flows into the recovery chamber 125 through the steam recovery port 122. A steam vent 123 is also provided on the water tank 120, through which the steam flowing back into the recovery chamber 125 can be discharged.

[0080] Because the water tank 120 contains water, the steam flowing into the recovery chamber 125 can exchange heat with the water, thereby lowering the steam temperature. The cooled steam in the recovery chamber 125 can then be discharged from the cooking equipment. Since the discharged steam is at a lower temperature, users around the cooking equipment are less likely to be scalded by the steam, improving user safety during cooking. Furthermore, the heat exchange between steam and water reduces the amount of steam emitted to the outside. Also, because the discharged steam is at a lower temperature, the temperature difference between the low-temperature steam and the cabinet is smaller, making it less likely for condensation to form on the cabinet, reducing the workload of cleaning condensation and providing convenience for users using the cooking equipment.

[0081] The steam generating assembly 140 is installed inside the evaporation chamber 124. The steam generating assembly 140 mainly heats the water in the evaporation chamber 124. When the steam in the cooking chamber 200 flows back into the recovery chamber 125, the steam may carry food juices, odors, etc. Since the water-blocking rib 130 can separate the evaporation chamber 124 and the recovery chamber 125, the steam in the recovery chamber 125 is not likely to enter the evaporation chamber 124. This reduces the probability of food juices and odors coming into contact with the water in the evaporation chamber 124, and reduces the probability of affecting the water quality in the evaporation chamber 124.

[0082] In one possible application, the water-proof rib 130 is integrally formed inside the water tank 120.

[0083] Combination Figure 3 and Figure 5 As shown, in some embodiments, optionally, the steam recovery port 122 and the exhaust port 123 are located on adjacent sides of the water tank 120.

[0084] Alternatively, the steam recovery port 122 and the exhaust port 123 are located on opposite sides of the water tank 120.

[0085] Alternatively, the steam recovery port 122 and the exhaust port 123 are located on opposite sides of the water tank 120.

[0086] After the steam flows back into the recovery chamber 125, the longer the steam flows in the recovery chamber 125, the longer the time for the steam to exchange heat with the water, thereby improving the cooling effect of the steam.

[0087] The steam recovery port 122 and the steam exhaust port 123 can be located on adjacent sides of the water tank 120, or on opposite sides of the water tank 120, or diagonally opposite sides of the water tank 120. Since the steam recovery port 122 and the steam exhaust port 123 are not located on the same side of the water tank 120, the steam exhaust port 123 can be located away from the steam recovery port 122, thus extending the time it takes for steam to flow from the steam recovery port 122 to the steam exhaust port 123.

[0088] In some embodiments, optionally, the circumference of the water tank 120 is set to C1, along the circumferential direction of the water tank 120 ( Figure 5 The arrow at point C points to the distance between the steam recovery port 122 and the exhaust port 123, which is C2, and C2 ≥ (1 / 3) × C1.

[0089] Along the circumference of the water tank 120, the distance between the steam recovery port 122 and the steam exhaust port 123 is at least one-third of the circumference of the water tank 120. Under the above conditions, the larger distance between the steam recovery port 122 and the steam exhaust port 123 can increase the time for steam to flow from the steam recovery port 122 to the steam exhaust port 123, thereby improving the heat exchange effect between steam and water.

[0090] like Figure 5 As shown, in some embodiments, optionally, the water tank 120 is provided with a maximum liquid level line 126, and the vent 123 is higher than the maximum liquid level line 126.

[0091] The water tank 120 is equipped with a maximum liquid level line 126. During the process of filling the water tank 120 with water, the maximum liquid level line 126 serves as a warning, reminding the user not to exceed the maximum liquid level line 126. In this design, the exhaust port 123 is positioned above the maximum liquid level line 126 to prevent water from the water tank 120 from entering the exhaust port 123, thus avoiding blockage and ensuring that steam in the recovery chamber 125 can be stably discharged through the exhaust port 123.

[0092] like Figure 5 As shown, in some embodiments, optionally, the height difference between the exhaust port 123 and the highest liquid level line 126 is H1, where H1 ≥ 10 mm.

[0093] There is a height difference between the vent 123 and the maximum liquid level line 126, and the vent 123 is located at least 10mm above the plane where the maximum liquid level line of the water tank 120 is located. When the water tank 120 shakes, the liquid level inside the water tank 120 will also fluctuate. Maintaining a certain distance between the vent 123 and the maximum liquid level line 126 can further prevent water from the water tank 120 from entering the vent 123.

[0094] For example, H1 is 10mm, 12mm or 15mm.

[0095] Combination Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, optionally, the water-proof rib 130 is provided with a water passage hole 131, and the evaporation chamber 124 and the recovery chamber 125 are connected through the water passage hole 131.

[0096] The steam generating assembly 140 heats the water in the evaporation chamber 124 to generate steam. During the steam generation process, the water in the evaporation chamber 124 will decrease. Since the evaporation chamber 124 and the recovery chamber 125 are connected through the water passage 131, the water in the recovery chamber 125 can be replenished into the evaporation chamber 124 to prevent the water in the recovery chamber 125 from burning dry.

[0097] When steam from the cooking chamber 200 flows back to the recovery chamber 125, it exchanges heat with the water in the recovery chamber 125, raising the water temperature. When the water from the recovery chamber 125 is replenished into the evaporation chamber 124, its temperature is not too low, allowing the steam generating assembly 140 to quickly heat the water and generate steam. Therefore, by exchanging heat between the water and steam in the recovery chamber 125, heat recovery from the steam is achieved. A portion of the steam is condensed and recovered after heat exchange with the water, while the remaining steam is discharged through the exhaust port 123. The steam generating assembly 140 can heat water to a certain temperature, allowing for faster cooking, improved degreasing rates, and reduced steam emissions. Furthermore, the rapid heating of water by the steam generating assembly 140 results in energy savings and extends the operating time of the water tank 120.

[0098] The steam in the recovery chamber 125 is not easily able to enter the evaporation chamber 124 due to the obstruction of water, which allows the water in the recovery chamber 125 to be replenished into the evaporation chamber 124. This reduces the probability of food juices and odors coming into contact with the water in the evaporation chamber 124, and reduces the probability of affecting the water quality in the evaporation chamber 124.

[0099] In this embodiment, the water passage hole 131 is located below the middle of the water-proof rib 130.

[0100] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, optionally, the water tank 120 includes: a water tank body 127 and a drip tray 128, a steam supply port 121 is provided on the drip tray 128, a recess 1271 is provided on the top edge of the water tank body 127, the drip tray 128 overlaps the top edge of the water tank body 127, and a steam recovery port 122 is formed between the drip tray 128 and the recess 1271.

[0101] The water tank body 127 is used to store water. The drip tray 128 is set on the top of the water tank body 127. The drip tray 128 seals the opening of the water tank 120. An inner cavity is formed between the drip tray 128 and the water tank body 127. When the steam generating component 140 is running, the water in the water tank 120 is heated. After steam is generated in the water tank 120, the steam is discharged into the cooking chamber 200 through the steam supply port 121 on the drip tray 128. Since the cooking chamber 200 is located above the drip tray 128, the steam discharged from the steam supply port 121 directly enters the cooking chamber 200, thereby ensuring that the high-temperature steam can quickly heat the food.

[0102] The cooking cavity 200 is located above the drip tray 128. During cooking, the drip tray 128 is used to collect and hold the juices flowing from the food, making it convenient for users to centrally process the juices and improving the ease of use of the cooking equipment. By using the drip tray 128 as the enclosure of the inner cavity, there is no need for additional components that cooperate with the water tank body 127, which simplifies the structure of the cooking equipment.

[0103] The juice receiving tray 128 overlaps the top edge of the water tank body 127, and a recess 1271 is provided on the top edge. At the position of the recess 1271, the juice receiving tray 128 does not contact the top edge of the water tank 120, thereby forming a steam recovery port 122 between the juice receiving tray 128 and the water tank body 127. Steam can flow into the recovery chamber 125 through the gap between the juice receiving tray 128 and the water tank body 127.

[0104] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the water tank 120 further includes: a first limiting rib 1291, the first limiting rib 1291 being disposed on the top of the water tank body 127, the first limiting rib 1291 being used to limit the translation of the juice receiving tray 128 relative to the water tank body 127.

[0105] A first limiting rib 1291 is provided on the top of the water tank body 127. The first limiting rib 1291 plays a limiting role in the juice tray 128, preventing the juice tray 128 from moving around on the top of the water tank body 127 and ensuring the stability of the juice tray 128.

[0106] In some embodiments, the first limiting rib 1291 may be higher than the edge of the juice receiving tray 128, or the first limiting rib 1291 may be flush with the edge of the juice receiving tray 128.

[0107] The first limiting rib 1291 needs to have a certain height in order to effectively limit the juice receiving tray 128. In this solution, the first limiting rib 1291 is limited to be higher than the juice receiving tray 128, or the first limiting rib 1291 is flush with the juice receiving tray 128, so as to prevent the juice receiving tray 128 from tilting and moving, and further improve the placement stability of the juice receiving tray 128.

[0108] like Figure 5 As shown, in some embodiments, optionally, the water tank 120 further includes: a second limiting rib 1292, the second limiting rib 1292 being disposed on the top of the water tank body 127, the first limiting rib 1291 being located between the drip tray 128 and the second limiting rib 1292, the first limiting rib 1291 and the second limiting rib 1292 having a gap 1293, the gap 1293 being for the steamer 300 or pot lid 400 of the cooking equipment to be placed on top.

[0109] The top of the water tank body 127 is also provided with a second limiting rib 1292, which is located outside the first limiting rib 1291. The first limiting rib 1291 and the second limiting rib 1292 are spaced apart. The bottom of the steamer 300 or the pot lid 400 can extend between the first limiting rib 1291 and the second limiting rib 1292, thereby limiting the position of the steamer 300 or the pot lid 400.

[0110] In this embodiment, the first limiting rib 1291 and the second limiting rib 1292 are integrally formed on the water tank body 127.

[0111] like Figure 5 As shown, in some embodiments, optionally, the height of the second limiting rib 1292 is H2, where H2 ≥ 5 mm.

[0112] The height of the second limiting rib 1292 is not less than 5mm. Increasing the corresponding area of ​​the second limiting rib 1292 and the steamer 300 in the height direction, or increasing the corresponding area of ​​the second limiting rib 1292 and the pot lid 400 in the height direction, is beneficial to improving the limiting effect of the second limiting rib 1292 on the steamer 300 or the pot lid 400.

[0113] For example, H2 is 5mm, 6mm or 10mm.

[0114] like Figure 5 As shown, in some embodiments, optionally, the second limiting rib 1292 includes an annular limiting rib, which is distributed along the circumference of the water tank 120.

[0115] In this design, the second limiting rib 1292 is a complete annular structure. When the steamer 300 or the pot lid 400 extends between the first limiting rib 1291 and the second limiting rib 1292, the groove between the side wall of the steamer 300 or the pot lid 400 and the second limiting rib 1292 stores the water condensed by the steam, thereby forming a seal and preventing steam leakage.

[0116] In some embodiments, the water tank 120 may optionally include a water tank body 127 and a drip tray 128, the drip tray 128 being attached to the top edge of the water tank body 127, and a steam supply port 121 and a steam recovery port 122 being disposed on the drip tray 128.

[0117] The drip tray 128 is placed on the water tank body 127. Holes can be made directly on the drip tray 128 and used as steam recovery ports 122. No changes to the structure of the water tank body 127 are required, reducing the processing difficulty of the cooking equipment.

[0118] Combination Figure 3 and Figure 4 As shown, in some embodiments, the base assembly 100 may optionally include a temperature sensor 150 connected to the water tank 120, with at least a portion of the temperature sensor 150 extending into the steam recovery port 122.

[0119] A temperature sensor 150 is installed at the steam recovery port 122 to detect the steam temperature inside the cooking chamber 200. Typically, after the cooking chamber 200 is filled with steam, the steam flows to the steam recovery port 122. Therefore, placing the temperature sensor 150 at the steam recovery port 122 can accurately reflect the temperature inside the cooking chamber 200.

[0120] like Figure 1 As shown, in some embodiments, optionally, the exhaust port 123 is located on the side of the water tank 120, and the water tank 120 is provided with a connecting pipe 600, which is connected to the exhaust port 123, and a portion of the connecting pipe 600 is bent relative to another portion.

[0121] When the vent 123 is located on the side of the water tank 120, if steam is discharged directly from the vent 123, it will flow directly towards the wall, easily causing condensation to form on the wall. This design restricts the steam flow from the vent 123 to the connecting pipe 600, which has a bend in its structure, preventing the steam from flowing directly towards the wall and thus avoiding condensation formation on the wall, reducing the amount of cleaning work required by the user.

[0122] Combination Figure 1 , Figure 2 and Figure 6As shown, in some embodiments, optionally, the steam generating assembly 140 includes: a heater 141 located in the evaporation chamber 124; the heater 141 includes an inner ring 142, an outer ring 143, and a heating element 144; a first air inlet channel 1451 is provided between the inner ring 142 and the outer ring 143, and the first air inlet channel 1451 is connected to the evaporation chamber 124; a second air inlet channel 1452 is provided in the inner ring 142, and the second air inlet channel 1452 is connected to the first air inlet channel 1451; a steam supply port 121 is connected to the second air inlet channel 1452; and the heating element 144 is used to heat the inner ring 142 and the outer ring 143.

[0123] Heater 141 is disposed in evaporation chamber 124. Heater 141 is provided with a first air inlet channel 1451 and a second air inlet channel 1452. The first air inlet channel 1451 is connected to evaporation chamber 124. When heater 141 is running, heater 141 can heat evaporation chamber 124. When the water in evaporation chamber 124 is heated into steam, the steam in evaporation chamber 124 can flow into the first air inlet channel 1451. Heater 141 can also heat the first air inlet channel 1451 and the second air inlet channel 1452, so that the steam flowing into the first air inlet channel 1451 can be reheated, thereby being heated into superheated steam in the first air inlet channel 1451 and the second air inlet channel 1452.

[0124] The first air intake channel 1451 and the second air intake channel 1452 are connected, allowing steam flowing into the first air intake channel 1451 to continue flowing into the second air intake channel 1452. By providing two sets of air intake channels within the heater 141, steam can flow sequentially through the first air intake channel 1451 and the second air intake channel 1452, extending the steam's flow time within the heater 141. The longer the steam flows within the heater 141, the longer it is reheated, effectively increasing its temperature. Through this method, the steam discharged into the cooking chamber 200 can reach temperatures above 100°C, shortening the cooking time and accelerating cooking efficiency. Furthermore, shortening the cooking time also prevents the loss of nutrients.

[0125] like Figure 7 As shown, the heating element 144 includes a first heating element 1441 for heating the inner ring 142 and a second heating element 1442 for heating the outer ring 143.

[0126] In this embodiment, the inner ring 142 and the outer ring 143 are an integral structure. In other embodiments, the inner ring 142 and the outer ring 143 can be separate structures.

[0127] The drip tray 128 closes the opening of the water-insulating rib 130 of the water tank 120 and partially closes the top of the inner ring 142 and the outer ring 143 of the heater 141, so that an evaporation chamber 124 is formed between the outer ring 143 of the heater 141 and the water-insulating rib 130, and a first superheated chamber (first air inlet channel 1451) is formed between the outer ring 143 and the inner ring 142 of the heater 141.

[0128] This embodiment designs a novel cooking device, including an evaporation chamber 124, a superheating chamber (the internal cavity of the heater 141), a cooking chamber 200, and a recovery chamber 125. The evaporation chamber 124 heats water to generate steam. The steam enters the superheating chamber and is heated into superheated steam. Then, the superheated steam enters the cooking chamber 200, raising the temperature inside the cooking chamber 200 to above 110°C, which can cook food faster and improve the degreasing rate of the food. Then, the steam enters the recovery chamber 125 from the cooking chamber 200.

[0129] Combination Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, optionally, the inner ring 142 has a first connecting port 146 on its side, the outer ring 143 has a second connecting port 147 on its side, the first air intake channel 1451 and the second air intake channel 1452 are connected through the first connecting port 146, the evaporation chamber 124 and the first air intake channel 1451 are connected through the second connecting port 147, and at least a portion of the first connecting port 146 is offset from the second connecting port 147.

[0130] Since at least a portion of the first connecting port 146 is misaligned with the second connecting port 147, some steam will not flow directly to the first connecting port 146, allowing some steam to flow circumferentially along the inner ring 142, thereby extending the steam flow time in the first air intake channel 1451 and further improving the steam heating time.

[0131] Combination Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, optionally, the first intake passage 1451 is circumferentially aligned with the inner ring 142. Figure 6 The distribution is indicated by the arrow at point D. The base assembly 100 also includes a connecting rib 148, which is located within the first air intake channel 1451 and between the first connecting port 146 and the second connecting port 147.

[0132] After steam flows into the first intake channel 1451, some steam flows clockwise relative to the inner ring 142, while other steam flows counterclockwise relative to the inner ring 142. To restrict the steam to flow in only one direction, a connecting rib 148 is provided between the first connecting port 146 and the second connecting port 147. The connecting rib 148 restricts the steam passage, allowing the steam to flow only in the direction away from the connecting rib 148. In this way, the steam flows in a predetermined direction. For example, in the predetermined direction, the path between the second connecting port 147 and the first connecting port 146 can be set to be longer, thereby increasing the steam flow time in the first intake channel 1451 and thus increasing the secondary heating time of the steam.

[0133] Combination Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, optionally, along the circumferential direction of the inner ring 142, the first connecting port 146 and the second connecting port 147 are arranged adjacent to each other, and the connecting rib 148 is spaced apart from the first connecting port 146 and the second connecting port 147.

[0134] The inner ring 142 has a first air intake channel 1451 distributed circumferentially. To prolong the heating time of steam within the first air intake channel 1451, it is necessary to increase the steam flow path within the first air intake channel 1451. The maximum flow path of steam within the first air intake channel 1451 is equal to the circumference of the first air intake channel 1451. To achieve this, the second connecting port 147 and the first connecting port 146 are arranged adjacent to each other, and a connecting rib 148 is provided between the second connecting port 147 and the first connecting port 146. Since the second connecting port 147 and the first connecting port 146 are adjacent, if no blocking component is provided between the second connecting port 147 and the first connecting port 146, the steam passing through the second connecting port 147 will flow directly to the first connecting port. To avoid this situation, a connecting rib 148 is provided between the second connecting port 147 and the first connecting port 146. The connecting rib 148 prevents the steam passing through the second connecting port 147 from flowing directly to the first connecting port 146. After the steam flows into the first intake channel 1451, the steam needs to flow in the first intake channel 1451 in a direction away from the connecting rib 148. After flowing a certain distance in the first intake channel 1451, the steam passes through the first connecting port 146 and flows into the second intake channel 1452 through the first connecting port 146.

[0135] Since the second connecting port 147 and the first connecting port 146 are arranged adjacent to each other, under the blocking effect of the connecting rib 148, the flow path of steam in the first air intake channel 1451 is basically equal to the circumference of the first air intake channel 1451, which extends the flow path of steam in the first air intake channel 1451 as much as possible, which is beneficial to improving the heating effect of steam.

[0136] In some embodiments, optionally, a first air intake channel 1451 is circumferentially distributed on the inner ring 142. After steam flows into the first air intake channel 1451, the steam flows circumferentially along the inner ring 142. The second connecting port 147 and the first connecting port 146 are distributed on opposite sides of the inner ring 142. Therefore, the flow path of steam in the first air intake channel 1451 is half the circumference of the first air intake channel 1451. With the above arrangement, the first connecting port 146 can be moved away from the second connecting port 147, extending the flow path of steam in the first air intake channel 1451 as much as possible and improving the heating effect of steam.

[0137] In one possible application, steam flows into the first intake channel 1451 through the second connection port 147. Within the first intake channel 1451, the steam splits into two streams, which flow along both sides of the inner ring 142 towards the first connection port 146, ultimately converging at the first connection port 146. The two streams can be heated simultaneously within the first intake channel 1451, which helps to increase the amount of steam heated per unit time and improves the steam heating efficiency.

[0138] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the steam generating assembly 140 further includes: a steam cylinder 149, which is connected to the water tank 120 and located in the second air inlet channel 1452. The steam cylinder 149 is provided with an exhaust channel 1491. The steam supply port 121 and the second air inlet channel 1452 are connected through the bottom of the exhaust channel 1491. The heating element 144 is also used to heat the steam cylinder 149.

[0139] A steam cylinder 149 is installed inside the second air intake channel 1452, and an exhaust channel 1491 is installed inside the steam cylinder 149. Since the heater 141 can also heat the steam cylinder 149, the surface temperature of the steam cylinder 149 and the temperature of the exhaust channel 1491 inside the steam cylinder 149 are both high. After steam flows into the second air intake channel 1452, the steam flows through the steam cylinder 149. Due to the high surface temperature of the steam cylinder 149, the steam cylinder 149 can continue to heat the steam. When the steam flows into the exhaust channel 1491, the exhaust channel 1491 further heats the steam.

[0140] In this design, the first connecting port 146 is higher than the bottom of the exhaust channel 1491. The steam in the first intake channel 1451 flows into the second intake channel 1452 through the first connecting port 146. Since the first connecting port 146 is higher than the bottom of the exhaust channel 1491, the steam flowing into the second intake channel 1452 diffuses from top to bottom. When the steam flows to the bottom of the steam cylinder 149, the steam can flow into the exhaust channel 1491.

[0141] When steam flows naturally, the higher-temperature steam tends to rise. This downward diffusion, which is opposite to the natural flow direction of steam, prolongs the steam's circulation time in the second intake channel 1452, increases the heat exchange of the steam, and continuously absorbs heat from the second intake channel 1452 and the surface heat of the steam cylinder 149 as the steam flows towards the exhaust channel 1491. This allows the steam to be heated into superheated steam, improving the heating efficiency of the food.

[0142] A steam cylinder 149 is provided between the drip tray 128 and the inner ring 142. A second superheated chamber (second air inlet channel 1452) is formed between the inner ring 142 and the steam cylinder 149. The inner ring 142 heats both the steam and the steam cylinder 149. The steam entering the inner ring 142 flows downward along the outer surface of the steam cylinder, then passes over the bottom of the steam cylinder 149, and flows upward along the inner surface of the steam cylinder 149 to the cooking chamber 200. During this process, the steam is reheated by the inner surface of the inner ring 142 and the surface of the steam cylinder 149.

[0143] In this embodiment, the steam cylinder 149 is connected to the bottom of the juice receiving tray 128.

[0144] 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.

[0145] like Figure 1 As shown, in some embodiments, the cooking device may optionally include a steamer 300 and a pot lid 400, with a gap 1293 between the first limiting rib 1291 and the second limiting rib 1292 in the base assembly 100, the gap 1293 being for the steamer 300 or the pot lid 400 to be placed on top of each other.

[0146] The cooking equipment also includes a steaming plate 500, which can be placed on the water tank 120 and then covered with the pot lid 400 for cooking. Alternatively, a steamer basket 300 can be placed on the water tank 120 and then covered with the pot lid 400.

[0147] The top of the water tank body 127 is provided with a first limiting rib 1291 and a second limiting rib 1292. The second limiting rib 1292 is located outside the first limiting rib 1291. The first limiting rib 1291 and the second limiting rib 1292 are spaced apart. The bottom of the steamer 300 or the pot lid 400 can extend between the first limiting rib 1291 and the second limiting rib 1292, thereby limiting the position of the steamer 300 or the pot lid 400.

[0148] In this design, the second limiting rib 1292 is a ring structure. When the steamer 300 or the pot lid 400 extends between the first limiting rib 1291 and the second limiting rib 1292, the groove between the side wall of the steamer 300 or the pot lid 400 and the second limiting rib 1292 stores the water condensed by the steam, thereby forming a seal and preventing steam leakage.

[0149] The first limiting rib 1291 can also limit the movement of the steaming plate 500.

The terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.
