Description

TECHNICAL FIELD

[0001] The utility model relates to cooking equipment technical field, specifically, a base assembly and cooking equipment. BACKGROUND

[0002] The existing cooking utensil usually sets up a fan to blow the control panel and condenses the steam, and the two fans not only occupy space but also increase cost. UTILITY MODEL CONTENTS

[0003] The utility model aims at solving one of the technical problems existing in prior art or related art.

[0004] Therefore, in a first aspect, the utility model provides a base assembly, which is used for a cooking equipment, and the cooking equipment comprises a cooking cavity, and the base assembly comprises: a base, which is provided with a mounting seat and an air inlet channel, and the air inlet channel is in communication with the mounting seat; a steam generation assembly, at least a part of which is located in the base, and the steam generation assembly is used for providing steam into the cooking cavity; a fan, which is located in the mounting seat, and the steam in the cooking cavity is used for being discharged outward through the fan; and a controller, which is arranged in the base, and external air is sucked into the mounting seat through the air inlet channel, and at least a part of the controller is located in the air inlet channel.

[0005] When the steam generation assembly operates, the steam generation assembly heats internal water to generate steam. The steam generation assembly is provided with a steam supply port, and the steam generated by the steam generation assembly can be discharged into the cooking cavity through the steam supply port, so that the food in the cooking cavity can be heated.

[0006] With the gradual increase of the amount of steam in the cooking cavity, the steam in the cooking cavity will flow to the fan. The air inlet channel is arranged in the base, and when the fan operates, the external air can be sucked into the mounting seat through the air inlet channel. The controller generates a large amount of heat when operating, so that the controller needs to be cooled. In the present scheme, at least a part of the controller is arranged in the air inlet channel, and the airflow flowing in the air inlet channel will pass through the controller, so that the controller can be cooled and the stable operation of the controller is ensured.

[0007] In the case that the external airflow and the steam are sucked into the fan, the external airflow can cool the steam to avoid scalding the user by the steam flowing outward. The fan can also cool the controller, and one fan plays a dual role, so that an additional cooling fan does not need to be arranged for the controller, the number of fans for cooling in the base assembly is reduced, the space occupation in the base assembly is reduced, and the cost of the present scheme is lower in the equipment with the same function.

[0008] In addition, the base assembly has the following additional technical features.

[0009] In some embodiments, a portion of the external air flowing into the air inlet channel passes through the controller and then flows to the fan, and another portion of the external air flowing into the air inlet channel bypasses the controller and then flows to the fan.

[0010] When the external air flows into the air inlet channel, a portion of the air passes through the controller, thereby achieving heat dissipation of the controller, and another portion of the air bypasses the controller, that is, another portion of the air does not pass through the controller and thus does not absorb the heat of the controller. In this way, the external air drawn in by the fan has a relatively low temperature, which is conducive to improving the cooling effect of the steam.

[0011] In some embodiments, the air inlet channel comprises a first channel in which at least a portion of the controller is located, and external air flowing into the first channel passes through the controller; and a second channel which is independently arranged from the first channel, and external air flowing into the second channel bypasses the controller.

[0012] The air inlet channel comprises two relatively independent channels, namely a first channel and a second channel, at least a portion of the controller is located in the first channel, and the air flowing into the first channel can dissipate heat from the controller. The air flowing into the second channel does not pass through the controller, so the air flowing into the second channel has a relatively low temperature. The air flowing into the first channel and the air flowing into the second channel are jointly drawn into the mounting seat. Since the air flowing into the second channel has a relatively low temperature, when the steam flowing back to the water tank is drawn into the mounting seat, the high-temperature steam mixes with the air flowing into the second channel, thereby reducing the temperature of the steam and the temperature of the steam discharged outward, further ensuring the safety of the user using the cooking device.

[0013] In some embodiments, the base assembly further comprises a partition plate located in the air inlet channel, the top and bottom of the partition plate are connected to the base, and the partition plate separates the air inlet channel into the first channel and the second channel.

[0014] The partition plate separates the internal space of the air inlet channel, and the first channel is on one side of the partition plate and the second channel is on the other side of the partition plate. The partition plate divides the air flowing into the air inlet channel into two independent air flows, thereby preventing the air flowing into the second channel from being affected by the heat of the controller.

[0015] In some embodiments, the air inlet channel is located on one side of the controller, and along the width direction of the air inlet channel, the air flowing into the air inlet channel near the controller dissipates heat from the controller, and the air flowing into the air inlet channel away from the controller bypasses the controller.

[0016] The air inlet channel can be provided with a large width, for example, along the width direction of the air inlet channel, the first side of the air inlet channel is adjacent to the controller, the second side of the air inlet channel is away from the controller, the airflow inside the first side of the air inlet channel can exchange heat with the controller, the airflow inside the second side of the air inlet channel is far away from the controller and is not easily affected by the heat of the controller, so as not to exchange heat with the controller. By providing the air inlet channel with a large width, it is not necessary to provide a flow dividing component in the air inlet channel, which is beneficial to simplify the structure of the base assembly.

[0017] In some technical solutions, the airflows in the first channel and the second channel are mixed and flow into the air inlet side of the fan.

[0018] When the airflows in the first channel and the second channel flow through the air inlet side of the fan, the airflows in the first channel and the second channel are mixed, and the mixed airflows are jointly sucked by the fan. A part of the air path exchanges heat with the controller and has a higher temperature. By mixing the steam in the first channel and the second channel and then flowing into the fan, the airflow with too high a temperature is avoided from directly flowing into the fan, thereby avoiding damage to the fan and being beneficial to reduce the damage rate of the fan.

[0019] In some technical solutions, the base is provided with a containing portion, the steam in the cooking cavity flows to the fan through the containing portion, the steam generating assembly is located in the containing portion, and the air inlet side of the fan faces the containing portion.

[0020] The containing portion is used for containing the steam generating assembly, the containing portion has a cavity structure, and as the amount of steam in the cooking cavity increases, part of the steam flows to the containing portion and then flows to the fan through the containing portion. The air inlet side of the fan faces the containing portion, so that the air inlet side of the fan is adjacent to the containing portion, the path of the steam flowing to the air inlet side is short, the steam is prevented from contacting other components on the flow path, and the damage rate of the internal structure of the base assembly is reduced.

[0021] In some technical solutions, a first gap is arranged between the side portion of the containing portion and the mounting seat, and the airflows in the first channel and the second channel flow into the fan through the first gap.

[0022] The first channel and the second channel are both connected to the first gap, so that the airflows in the first channel and the second channel are mixed in the first gap. The first gap is connected to the inside of the mounting seat, and the airflows in the first channel and the second channel flow into the mounting seat after being mixed in the first gap.

[0023] The airflows in the first channel and the second channel are converged through the first gap, so that it is not necessary to connect the first channel and the second channel to the mounting seat respectively, thereby avoiding that the first channel and the second channel occupy too much space in the base, and the space utilization rate inside the base is improved.

[0024] In some embodiments, the base is provided with a first air hole on the outer surface thereof, and the first channel and the second channel are both in communication with the first air hole.

[0025] The first air hole is formed on the base, and external air can flow into the first channel and the second channel through the first air hole. The first channel and the second channel are both in communication with the first air hole, so that the first channel and the second channel can be close to each other, for example, the first channel and the second channel can be separated by only one separation component, and the first channel and the second channel are simple to process. Moreover, the first channel and the second channel are in communication with the first air hole at the same time, which can save the workload of opening holes at different positions of the base.

[0026] In a possible application, the first air hole is large in size, so that the end of the first channel and the end of the second channel are in communication with the first air hole at the same time.

[0027] In a possible application, the first air hole includes a plurality of sub-holes, and the plurality of sub-holes are close to each other and distributed in a part of the first channel and a part of the second channel.

[0028] In some embodiments, the distance between the first air hole and the top of the base is greater than the distance between the first air hole and the bottom of the base.

[0029] The first air hole is close to the bottom of the base, and the position of the first air hole is not easy to be seen by a user, thereby avoiding affecting the integrity of the base.

[0030] In some embodiments, the base includes a bottom wall, a side wall and a transition section, the transition section is used for connecting the bottom wall and the side wall, and the first air hole is arranged on the transition section and / or the bottom wall.

[0031] The transition section is used for connecting the side wall and the bottom wall, so that the transition section is located at a lower position in the base. The first channel and the second channel are both in communication with the first air hole, so that the first air hole has a large opening area. Arranging the first air hole on the transition section and / or the bottom wall can help a user not to notice the first air hole when using the cooking device, thereby improving the integrity of the cooking device.

[0032] The transition section is usually a slope or a curved surface. When the first air hole is arranged on the transition section, the first air hole is not easy to be blocked, thereby ensuring stable air intake of the first channel and the second channel. When the first air hole is arranged on the bottom wall, a supporting leg needs to be arranged below the base, so that the base is lifted above a workbench, thereby avoiding blocking the first air hole on the bottom wall.

[0033] In some embodiments, the accommodating portion is provided with a second air hole, the second air hole is in communication with the first gap, and the steam in the cooking cavity is sequentially sucked into the fan through the second air hole and the first gap.

[0034] The steam flowing into the accommodating portion has a high temperature. In the process of flowing to the mounting base, the steam first flows into the first gap through the second opening hole, so that the high-temperature steam is mixed with the external gas flowing into the first gap, and then the mixed gas flows into the mounting base. The temperature of the mixed gas has been reduced, and the mixed gas flowing into the mounting base will not have a too high temperature.

[0035] By connecting the accommodating portion and the first gap, the high-temperature steam is prevented from directly flowing into the mounting base, so that the damage of the high-temperature steam to the fan is avoided, and the operation stability of the fan is ensured.

[0036] In some technical solutions, optionally, a fourth air hole is arranged on the outer surface of the base, and the fan is further configured to suck the external gas through the fourth air hole. The fourth air hole is arranged at intervals with the first air hole.

[0037] The fourth opening hole is arranged on the base. When the fan is running, the external gas can be sucked into the mounting base through the fourth opening hole. No controller is arranged between the fourth opening hole and the mounting base. The temperature of the gas flowing into the mounting base through the fourth opening hole is low, so that the steam can be effectively cooled.

[0038] Since the first opening hole is close to the bottom of the base, the first opening hole may be blocked by other components placed on the workbench surface, affecting the normal air intake of the first opening hole. By arranging the fourth opening hole on the base, even if the first opening hole is blocked, the fourth opening hole can still intake air, so that the steam can be cooled.

[0039] In some technical solutions, optionally, the distance between the fourth air hole and the second air hole is less than the distance between the first air hole and the second air hole.

[0040] The distance between the fourth air hole and the second air hole is small, so that the external gas flow can be quickly mixed with the steam. The temperature of the gas flow flowing into the fourth air hole is low, so that the temperature of the steam can be quickly reduced, avoiding the steam flowing out of the accommodating portion for a long time at a high temperature, and avoiding damage to other components in the base.

[0041] In some technical solutions, optionally, the fourth air hole is higher than the first air hole.

[0042] The height of the fourth air hole is higher than that of the first air hole. The fourth air hole is not easily blocked by other components on the workbench surface, so that the fourth air hole can stably supplement the gas into the mounting base, thereby stably cooling the steam.

[0043] In some technical solutions, optionally, the distance between the fourth air hole and the top of the base is less than the distance between the fourth air hole and the bottom of the base.

[0044] The fourth air hole is close to the top of the base due to the small spacing between the fourth air hole and the top of the base, the fourth air hole has a high height, the fourth air hole is not easy to be blocked, and external airflow can stably flow into the base.

[0045] In some embodiments, a second gap is arranged between the accommodating portion and the mounting base, the fourth air hole and the air inlet side of the fan are communicated through the second gap, and the width of the second gap is less than or equal to 1 cm.

[0046] The steam flowing into the fourth air hole flows to the air inlet side of the fan through the second gap between the accommodating portion and the mounting base, the width of the second gap is small, so that the steam can flow to the air inlet side at a high flow rate, which is beneficial to improve the air inlet efficiency and improve the cooling effect of the steam.

[0047] In some embodiments, the fourth air hole is communicated with the mounting base through the first gap.

[0048] After the external gas flows into the first gap through the fourth air hole, the external gas is mixed with the high-temperature steam in the first gap and then flows into the mounting base, so that the high-temperature steam does not directly contact the fan, thereby reducing the damage rate of the fan.

[0049] The external gas flowing into the first air hole and the fourth air hole is mixed with the steam in the first gap, and no additional channel needs to be arranged for the steam flowing into the fourth air hole, which is beneficial to improve the space utilization rate of the base assembly.

[0050] In some embodiments, the base assembly further comprises a juice receiving disc arranged on the steam generating assembly and / or the accommodating portion, a gas guiding channel is formed between the juice receiving disc and the accommodating portion, and the steam in the cooking cavity flows to the second air hole through the gas guiding channel.

[0051] The cooking cavity is located above the juice receiving disc, and the juice receiving disc is used for receiving and collecting juice flowing from the food material during cooking, so that the user can conveniently collect the juice flowing from the food material, and the use convenience of the cooking equipment is improved. When the juice receiving disc is arranged on the accommodating portion, the top of the accommodating portion is covered, and no additional component needs to be arranged to cooperate with the accommodating portion, so that the structure of the cooking equipment is simplified.

[0052] When the juice receiving disc covers the accommodating portion, a gas guiding channel is formed between the juice receiving disc and the accommodating portion, and the steam flowing back to the accommodating portion flows to the second air hole along the gas guiding channel.

[0053] The juice receiving disc is arranged on the top of the accommodating portion, so that the gas guiding channel is also located at the top of the accommodating portion, and when water is stored in the accommodating portion, the water in the accommodating portion is not easy to flow over the gas guiding channel, the gas guiding channel is only used for steam to pass through, and the water in the accommodating portion is prevented from being sucked into the mounting base.

[0054] In some embodiments, the receiving portion is provided with a bearing surface, and a portion of the juice receiving disc is supported on the bearing surface, and the second air hole is higher than the bearing surface.

[0055] In the case of installing the juice receiving disc, a portion of the juice receiving disc is supported on the bearing surface in the receiving portion, and the bearing surface supports the juice receiving disc.

[0056] During cooking, condensate water is generated on the juice receiving disc, and a portion of the condensate water drops on the bearing surface along the juice receiving disc. In this embodiment, the second air hole is raised above the bearing surface, so that the condensate water on the bearing surface is not easy to enter the second air hole, thereby avoiding the condensate water flowing into the mounting seat and damaging the fan.

[0057] In some embodiments, the base assembly further comprises a surrounding rib provided on the juice receiving disc, the bottom of the surrounding rib is higher than the bottom of the receiving portion, the surrounding rib is distributed along the circumference of the steam generating assembly, one side of the surrounding rib adjacent to the second air hole is provided with a third air hole, and the steam in the cooking cavity flows to the first gap through the third air hole.

[0058] The bottom of the juice receiving disc is provided with a surrounding rib, the surrounding rib is in a ring structure, and the surrounding rib is distributed along the circumference of the steam generating assembly. The surrounding rib extends into the receiving portion, and the surrounding rib encloses a relatively closed space in the receiving portion.

[0059] A third opening is provided on the surrounding rib, the third opening is adjacent to the air guide channel, and the steam flowing back into the receiving portion flows to the air guide channel through the third opening and then flows into the first gap. In this way, the steam flowing back into the receiving portion only flows out through the third opening, so that the steam can be discharged outward by the fan, thereby avoiding the steam flowing out from the gap between the shell of the cooking device and the receiving portion, and ensuring that the steam flowing outward is subjected to temperature reduction, thereby avoiding scalding the user.

[0060] In some embodiments, the receiving portion comprises a water tank body, the steam flowing back into the water tank body exchanges heat with the water in the water tank body, and an air guide portion is provided at the top of the water tank body, and the second air hole is provided on one side of the air guide portion adjacent to the edge of the water tank body.

[0061] The second air hole is provided on the air guide portion, and the second air hole is located on one side of the air guide portion away from the center of the water tank body, so as to prolong the path of the steam flowing to the second air hole. The longer the path of the steam flow, the lower the temperature of the steam, thereby better achieving the temperature reduction effect of the steam.

[0062] As the amount of steam in the cooking cavity gradually increases, the steam in the cooking cavity flows back into the water tank, and the steam flowing into the water tank can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The user around the cooking device is not easy to be scalded by the discharged steam, which is conducive to improving the safety of the user during cooking.

[0063] In the heat exchange process of steam and water in the inner cavity, the heat of high-temperature steam is transferred to the water, thereby realizing the recovery of steam heat and avoiding waste of steam heat. In addition, the water can be heated by high-temperature steam, so that the temperature of the water is increased, and the heating time of the steam generation assembly is reduced, thereby reducing the energy consumption of the steam generation assembly, and the utilization rate of energy is improved.

[0064] In a second aspect, the utility model provides a kind of cooking equipment, comprising: shell, cooking cavity is equipped in shell;As in the base component of first aspect, shell is located on base component.

[0065] In some technical solutions, optionally, steam backflow channel is equipped in shell, one end of steam backflow channel extends towards the top of shell, another end of steam backflow channel is communicated with the accommodating portion in base component, and steam in cooking cavity flows to the accommodating portion through steam backflow channel.

[0066] After steam flows into cooking cavity, steam rises in cooking cavity, and when steam flows to the top of cooking cavity, steam flows into steam backflow channel. When part of steam flows to the top of cooking cavity, steam substantially fills cooking cavity, so that the temperature of each part in cooking cavity is relatively high, ensuring uniform and hot effect of steam on food materials. Steam is condensed in the accommodating portion by backflowing through steam backflow channel, so that the opening for discharging steam does not need to be arranged on the shell, avoiding scalding users.

DETAILED DESCRIPTION

[0079] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model will be further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0080] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the protection scope of the utility model is not limited by the specific embodiments disclosed below.

[0081] The following refers to Figures 1 to 8 The base assembly and the cooking equipment provided according to some embodiments of the utility model are described.

[0082] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments of the utility model, propose a base assembly 100, base assembly 100 is used for cooking equipment. Cooking equipment includes cooking cavity 210, base assembly 100 includes: base 110, steam generation assembly 130, fan 140 and controller 150, base 110 is equipped with mounting seat 111 and air inlet channel 112, air inlet channel 112 is communicated with mounting seat 111. At least a part of steam generation assembly 130 is located in base 110, steam generation assembly 130 is used to provide steam to cooking cavity 210. Fan 140 is located in mounting seat 111, steam in cooking cavity 210 is discharged outward through fan 140, controller 150 is located in base 110, external gas is sucked by fan through air inlet channel 112, at least a part of controller 150 is located in air inlet channel 112.

[0083] Figure 2 In the figure, solid arrows are used to represent steam flow paths, and dashed arrows are used to represent cold air flow paths, Figure 3 In the figure, the arrows have the same meaning as Figure 2 In the figure, the arrows have the same meaning as

[0084] When steam generation assembly 130 is running, steam generation assembly 130 heats the water in the internal heating cavity 135 to generate steam. Steam generation assembly 130 is provided with a steam supply port 136, and the steam generated by steam generation assembly 130 can be discharged into cooking cavity 210 through steam supply port 136, so that the food in cooking cavity 210 can be heated.

[0085] As the amount of steam in cooking cavity 210 gradually increases, the steam in cooking cavity 210 will flow to fan 140. Air inlet channel 112 is provided on base 110, and when fan 140 is running, external gas can be sucked into mounting seat 111 through air inlet channel 112. Air inlet 113 is provided on mounting seat 111, and gas is sucked into mounting seat 111 through air inlet 113. Controller 150 generates a lot of heat when running, so it is necessary to dissipate heat from controller 150. In this scheme, at least a part of controller 150 is arranged in air inlet channel 112, and the airflow flowing in air inlet channel 112 will pass through controller 150, so that controller 150 can be cooled, ensuring the stable operation of controller 150.

[0086] In the case that the external airflow and the steam are both drawn in by the fan 140, the external airflow can cool the steam, so as to avoid that the steam flowing outwards burns the user. The fan 140 can also cool the controller 150, and one fan 140 plays a dual role, so that an additional cooling fan 140 does not need to be additionally arranged for the controller 150, the number of fans 140 for cooling in the base assembly 100 is reduced, the space occupation in the base assembly 100 is reduced, and the cost of the device with the same function is lower.

[0087] One fan 140 can simultaneously cool the water vapor, then rapidly disperse the steam, reduce the visibility of the steam after being discharged, and reduce the temperature of the discharged steam, so as to prevent the steam from burning people, and the fan 140 can also cool and heat the controller 150, so that the problem that two fans 140 are needed to simultaneously realize the two functions is solved.

[0088] The exhaust port 114 is arranged on the base 110, the mixed gas after the steam and the external gas supplemented by the air inlet channel 112 is discharged outwards under the action of the fan 140 through the exhaust port 114, the air inlet channel 112 is arranged, and the negative pressure of the exhaust port 114 is reduced, so as to avoid that the steam in the air inlet channel 112 is discharged too fast, and the steam can effectively heat the food in the cooking cavity 210.

[0089] In some embodiments, optionally, part of the airflow entering the air inlet channel 112 from the outside flows to the fan 140 after passing through the controller 150, and the other part of the airflow flows to the fan 140 after bypassing the controller 150.

[0090] In the case that the external gas flows into the air inlet channel 112, part of the airflow passes through the controller 150, so as to cool the controller 150, and the other part of the steam bypasses the controller 150, that is, the other part of the airflow does not pass through the controller 150, so as not to absorb the heat of the controller 150. In the above manner, the external airflow drawn in by the fan 140 has a lower temperature, which is beneficial to improve the cooling effect of the steam.

[0091] As shown in FIG. 1, Figure 3 In some embodiments, optionally, the air inlet channel 112 includes a first channel 1121 and a second channel 1122, at least part of the controller 150 is located in the first channel 1121, and the external gas flowing into the first channel 1121 passes through the controller 150. The second channel 1122 is independently arranged with the first channel 1121, and the external gas flowing into the second channel 1122 bypasses the controller 150.

[0092] The air inlet channel 112 includes two relatively independent channels, namely a first channel 1121 and a second channel 1122. At least a part of the controller 150 is located in the first channel 1121. The air flowing into the first channel 1121 can dissipate heat from the controller 150. The air flowing into the second channel 1122 does not pass through the controller 150, and thus the air flowing into the second channel 1122 has a lower temperature. The air flowing into the first channel 1121 and the air flowing into the second channel 1122 are jointly drawn into the mounting seat 111. Since the air flowing into the second channel 1122 has a lower temperature, when the steam flowing back to the containing portion 120 is drawn into the mounting seat 111, the high-temperature steam mixes with the air flowing into the second channel 1122, thereby reducing the temperature of the steam and reducing the temperature of the steam discharged outward, further ensuring the safety of the user using the cooking device.

[0093] In combination Figure 2 and Figure 3 In some embodiments, the base assembly 100 optionally further includes a partition plate 190 located in the air inlet channel 112. The top and bottom of the partition plate 190 are connected to the base 110. The partition plate 190 separates the air inlet channel 112 into the first channel 1121 and the second channel 1122.

[0094] The partition plate 190 separates the internal space of the air inlet channel 112. On one side of the partition plate 190 is the first channel 1121, and on the other side of the partition plate 190 is the second channel 1122. The partition plate 190 divides the air flowing into the air inlet channel 112 into two independent air flows, preventing the air flowing into the second channel 1122 from being affected by the heat of the controller 150.

[0095] In some embodiments, the air inlet channel 112 is located on one side of the controller 150. Along the width direction of the air inlet channel 112, the air flowing into the air inlet channel 112 near the controller 150 dissipates heat from the controller 150, and the air flowing into the air inlet channel 112 away from the controller 150 bypasses the controller 150.

[0096] The air inlet channel 112 can be provided with a large width. For example, along the width direction of the air inlet channel 112, the first side of the air inlet channel 112 is adjacent to the controller 150, and the second side of the air inlet channel 112 is away from the controller 150. The air inside the first side of the air inlet channel 112 can exchange heat with the controller 150, and the air inside the second side of the air inlet channel 112 is far away from the controller 150 and is not easily affected by the heat of the controller 150, so as not to exchange heat with the controller 150. By providing the air inlet channel 112 with a large width, it is not necessary to provide a flow dividing component in the air inlet channel 112, which is conducive to simplifying the structure of the base assembly 100.

[0097] In combination Figure 2 And Figure 3 As shown in FIG. 12, in some embodiments, the air flow in the first channel 1121 and the second channel 1122 is mixed by the air inlet side of the fan 140, and the air flow passing through the fan 140 flows out from the air outlet side 142 of the fan 140.

[0098] The air flow in the first channel 1121 and the second channel 1122 is mixed when passing through the air inlet side of the fan 140, and the mixed air flow is sucked into the fan 140 together. A part of the air path exchanges heat with the controller 150 and has a higher temperature. By mixing the steam in the first channel 1121 and the second channel 1122 and then flowing into the fan 140, the air flow with too high a temperature is avoided from directly flowing into the fan 140, thereby avoiding damage to the fan 140 and facilitating reduction of the damage rate of the fan 140.

[0099] In combination Figure 2 And Figure 3 As shown in FIG. 12, in some embodiments, the base 110 is provided with a containing portion 120, the steam in the cooking cavity 210 flows to the fan 140 through the containing portion 120, the steam generating assembly 130 is located in the containing portion 120, and the air inlet side of the fan 140 faces the containing portion 120.

[0100] The containing portion 120 is used for containing the steam generating assembly 130, and the containing portion 120 is a hollow structure. As the amount of steam in the cooking cavity 210 increases, part of the steam flows to the containing portion 120 and then flows to the fan 140 through the containing portion 120. The air inlet side of the fan 140 faces the containing portion 120, so that the air inlet side of the fan 140 is adjacent to the containing portion 120, the path of the steam flowing to the air inlet side is short, the steam is prevented from contacting other components on the flow path, and the damage rate of the internal structure of the base assembly 100 is reduced.

[0101] Exemplarily, the containing portion 120 can be a water tank, the steam generating assembly 130 is in communication with the water tank, and the water in the water tank can be supplemented into the heating cavity 135 of the steam generating assembly 130.

[0102] As the amount of steam in the cooking cavity 210 gradually increases, the steam in the cooking cavity 210 flows back to the water tank. The steam flowing into the water tank can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The user around the cooking device is not easily scalded by the discharged steam, and the safety of the user in the cooking process is improved.

[0103] In the heat exchange process between the steam and the water in the water tank, the heat of the high-temperature steam is transferred to the water, thereby realizing the recovery of the steam heat and avoiding the waste of the steam heat. In addition, the water can be heated by the high-temperature steam, so that the temperature of the water can be increased, and the heating time of the water by the steam generation assembly can be reduced, thereby reducing the energy consumption of the steam generation assembly and being beneficial to improving the energy utilization rate.

[0104] In a possible application, the steam generation assembly 130 includes a focusing ring 131 and a heating piece 132. The focusing ring 131 is located in the water tank, and the heating piece 132 is installed at the bottom of the water tank and located below the focusing ring 131. The heating piece 132 can heat the water in the focusing ring 131.

[0105] As shown in Figure 8 In a possible application, the focusing ring 131 includes an inner cylinder 133 and an outer cylinder 134. The inner cylinder 133 and the outer cylinder 134 are connected, and the inner cylinder 133 is located inside the outer cylinder 134. The steam supply port 136 is arranged on the inner cylinder 133, and the space inside the inner cylinder 133 serves as a heating cavity 135. The inner cavity of the outer cylinder 134 is in communication with the water tank. For example, a hole can be formed in the outer cylinder 134, or a notch is arranged at the bottom of the outer cylinder 134, so that the water in the water tank can be supplemented into the outer cylinder 134. A hole is formed at the bottom of the inner cylinder 133, so that the water in the outer cylinder 134 can be supplemented into the inner cylinder 133. The space in the inner cylinder 133 is small, and a small amount of water in the inner cylinder 133 can be quickly heated into steam, thereby improving the steam generation speed.

[0106] As shown in Figure 3 In some embodiments, a first gap 160 is arranged between the side of the accommodating portion 120 and the mounting seat 111. The airflow in the first channel 1121 and the second channel 1122 flows into the fan 140 through the first gap 160.

[0107] The first channel 1121 and the second channel 1122 are both in communication with the first gap 160, so that the airflow in the first channel 1121 and the second channel 1122 is mixed in the first gap 160. The first gap 160 is in communication with the inside of the mounting seat 111, and the airflow in the first channel 1121 and the second channel 1122 flows into the mounting seat 111 after being mixed in the first gap 160.

[0108] The airflow in the first channel 1121 and the second channel 1122 is converged through the first gap 160, so that the first channel 1121 and the second channel 1122 do not need to be respectively communicated with the mounting seat 111, thereby avoiding that the first channel 1121 and the second channel 1122 occupy too much space in the base 110 and being beneficial to improving the space utilization rate of the inside of the base 110.

[0109] In combinationFigure 3 、 Figure 4 and Figure 5 As shown in FIG. 1, in some embodiments, a first air hole 115 is optionally formed on the outer surface of the base 110, and the first channel 1121 and the second channel 1122 are both in communication with the first air hole 115.

[0110] The first air hole 115 is formed on the base 110, and the external gas can flow into the first channel 1121 and the second channel 1122 through the first air hole 115. The first channel 1121 and the second channel 1122 are both in communication with the first air hole 115, so that the first channel 1121 and the second channel 1122 can be close to each other, for example, only one separation component can separate the first channel 1121 and the second channel 1122 from each other, and the first channel 1121 and the second channel 1122 are relatively simple to process. Moreover, the first channel 1121 and the second channel 1122 are in communication with the first air hole 115 at the same time, which can save the workload of opening holes at different positions of the base 110.

[0111] Figure 5 In the figure, the solid arrow represents the steam flow path, the dashed arrow represents the cold air flow path, and the curved arrow represents the cooled steam flow path.

[0112] In the embodiment, the first air hole 115 is arranged above the fan 140, and the controller 150 is arranged below the fan 140. In other embodiments, the first air hole 115 and the controller 150 can also be distributed at other positions.

[0113] In a possible application, the first air hole 115 has a large opening, so that the end of the first channel 1121 and the end of the second channel 1122 are in communication with one first opening at the same time.

[0114] In a possible application, the first air hole 115 includes a plurality of sub-openings, and the plurality of sub-openings are close to each other and distributed in part in communication with the first channel 1121 and in part in communication with the second channel 1122.

[0115] As shown in FIG. 1, in some embodiments, the distance between the first air hole 115 and the top of the base 110 is greater than the distance between the first air hole 115 and the bottom of the base 110. Figure 4 The first air hole 115 is close to the bottom of the base 110, and the position of the first air hole 115 is not easy to be seen by the user, so as to avoid affecting the integrity of the base 110.

[0116] As shown in FIG. 1, in some embodiments, the distance between the first air hole 115 and the top of the base 110 is greater than the distance between the first air hole 115 and the bottom of the base 110.

[0117] Figure 4 ​As shown, in some embodiments, the base 110 optionally comprises a bottom wall 1161, a side wall 1162, and a transition section 1163 connecting the bottom wall 1161 and the side wall 1162. The first air hole 115 is arranged on the transition section 1163 and / or the bottom wall 1161.

[0118] The transition section 1163 is used to connect the side wall 1162 and the bottom wall 1161, and thus is located at a lower position in the base 110. The first air hole 115 is in communication with the first channel 1121 and the second channel 1122, and thus has a large opening area. Arranging the first air hole 115 on the transition section 1163 and / or the bottom wall 1161 makes it less noticeable to users when using the cooking device, which is conducive to improving the integrity of the cooking device.

[0119] The transition section 1163 is generally inclined or curved. When the first air hole 115 is arranged on the transition section 1163, the first air hole 115 is less likely to be blocked, ensuring stable air intake of the first channel 1121 and the second channel 1122. When the first air hole 115 is arranged on the bottom wall 1161, a support needs to be arranged below the base 110 to raise the base 110 above the workbench, avoiding blocking of the first air hole 115 on the bottom wall 1161.

[0120] In combination with Figure 3 and Figure 6 As shown, in some embodiments, the accommodation portion 120 is provided with a second air hole 121 in communication with the first gap 160. The steam in the cooking cavity 210 is sequentially drawn into the fan 140 through the second air hole 121 and the first gap 160.

[0121] The steam flowing back into the accommodation portion 120 has a high temperature. During the process of flowing to the mounting seat 111, the steam first flows into the first gap 160 through the second air hole 121, so that the high-temperature steam is mixed with external air flowing into the first gap 160, and then flows into the mounting seat 111 together. The temperature of the mixed gas has been reduced, and the mixed gas flowing into the mounting seat 111 will not have excessively high temperature.

[0122] By connecting the accommodation portion 120 and the first gap 160, the high-temperature steam is prevented from directly flowing into the mounting seat 111, thereby avoiding damage to the fan 140 by the high-temperature steam and ensuring stable operation of the fan 140.

[0123] In combination with Figure 3 and Figure 4As shown, in some embodiments, optionally, a fourth vent 117 is provided on the outer surface of the base 110, and the fan 140 is also used to draw in external gas through the fourth vent 117, with the fourth vent 117 being spaced apart from the first vent 115.

[0124] A fourth vent 117 is provided on the base 110. When the fan 140 is running, external gas can be drawn into the mounting base 111 through the fourth vent 117. No controller 150 is provided between the fourth vent 117 and the mounting base 111. The temperature of the gas flowing into the mounting base 111 through the fourth vent 117 is low, which can effectively cool the steam.

[0125] Since the first vent 115 is close to the bottom of the base 110, the first vent 115 may be blocked by other components placed on the workbench, affecting the normal air intake of the first vent 115. By setting a fourth vent 117 on the base 110, even if the first vent 115 is blocked, the fourth vent 117 can still take in air, thereby ensuring that the steam can be cooled.

[0126] like Figure 4 As shown, in some embodiments, optionally, the distance between the fourth vent 117 and the second vent 121 is less than the distance between the first vent 115 and the second vent 121.

[0127] The distance between the fourth vent 117 and the second vent 121 is small, allowing the external airflow to mix quickly with the steam. Furthermore, the airflow flowing into the fourth vent 117 is at a lower temperature, which quickly reduces the temperature of the steam, preventing the steam exiting the containment 120 from remaining at a high temperature for an extended period and thus avoiding damage to other components within the base 110.

[0128] Combination Figure 3 and Figure 4 As shown, in some embodiments, optionally, the fourth pore 117 is higher than the first pore 115.

[0129] The fourth vent 117 is higher than the first vent 115, and the fourth vent 117 is not easily blocked by other parts on the workbench, ensuring that the fourth vent 117 can stably replenish gas into the mounting base 111, thereby stably cooling the steam.

[0130] In some embodiments, the distance between the fourth vent 117 and the top of the base 110 is optionally smaller than the distance between the fourth vent 117 and the bottom of the base 110.

[0131] The distance between the fourth vent 117 and the top of the base 110 is small, so the fourth vent 117 is close to the top of the base 110. The fourth vent 117 is relatively high, so it is not easily blocked, ensuring that the external airflow can flow steadily into the base 110.

[0132] As shown in Figure 3 some embodiments, optionally, a second gap 162 is provided between the accommodation portion 120 and the mounting base 111, the fourth air hole 117 and the air inlet side 141 of the fan 140 are in communication through the second gap 162, and the width W of the second gap 162 is less than or equal to 1 cm.

[0133] The airflow flowing into the fourth air hole 117 flows to the air inlet side 141 of the fan 140 through the second gap 162 between the accommodation portion 120 and the mounting base 111, and the width of the second gap 162 is small, thereby ensuring that the steam can flow to the air inlet side 141 at a high flow rate, which is conducive to improving the air inlet efficiency and improving the cooling effect of the steam.

[0134] As shown in Figure 3 some embodiments, optionally, the fourth air hole 117 is in communication with the mounting base 111 through the first gap 160.

[0135] After the external gas flows into the first gap 160 through the fourth air hole 117, the external gas mixes with the high-temperature steam in the first gap 160 and then flows into the mounting base 111, thereby avoiding direct contact between the high-temperature steam and the fan 140, and reducing the damage rate of the fan.

[0136] The external gas flowing into the first air hole 115 and the fourth air hole 117 is mixed with the steam in the first gap 160, and no additional channel needs to be provided for the airflow flowing into the fourth air hole 117, which is conducive to improving the space utilization rate in the base assembly 100.

[0137] As shown in Figure 2 and Figure 3 some embodiments, optionally, the base assembly 100 further comprises a juice receiving disc 170 provided on the steam generation assembly 130 and / or the accommodation portion 120, a gas guiding channel 171 is formed between the juice receiving disc 170 and the accommodation portion 120, and the steam in the cooking cavity 210 flows to the second air hole 121 through the gas guiding channel 171.

[0138] The cooking cavity 210 is located above the juice receiving disc 170, and the steam generation assembly 130 and / or the accommodation portion 120 supports the juice receiving disc 170. During cooking, the juice receiving disc 170 is used to receive and collect the juice flowing from the food materials, which is convenient for the user to centrally process the juice flowing from the food materials, and is conducive to improving the user's convenience in using the cooking equipment. When the juice receiving disc 170 is placed on the accommodation portion 120, the top of the accommodation portion 120 is covered, and no additional component needs to be provided to cooperate with the accommodation portion 120, which is conducive to simplifying the structure of the cooking equipment.

[0139] When the drip tray 170 is placed on the accommodating portion 120, a gas channel 171 is formed between the drip tray 170 and the accommodating portion 120, and the steam flowing back into the accommodating portion 120 flows along the gas channel 171 to the second vent 121.

[0140] The juice receiving tray 170 is located at the top of the accommodating part 120, so the air guide channel 171 is also located at the top of the accommodating part 120. Water in the accommodating part 120 does not easily pass through the air guide channel 171. The air guide channel 171 is only for steam to pass through, so as to prevent water in the accommodating part 120 from being sucked into the mounting base 111.

[0141] Combination Figure 3 and Figure 6 As shown, in some embodiments, optionally, the receiving portion 120 is provided with a bearing surface 122, a portion of the drip tray 170 abuts against the bearing surface 122, and the second air hole 121 is higher than the bearing surface 122.

[0142] When the juice tray 170 is installed, a portion of the juice tray 170 is placed against the bearing surface 122 in the receiving part 120, and the bearing surface 122 supports the juice tray 170.

[0143] During cooking, condensation will occur on the drip tray 170. Some of the condensation will drip down the drip tray 170 onto the bearing surface 122. In this design, the second vent 121 is raised above the bearing surface 122, so that the condensation on the bearing surface 122 is less likely to enter the second vent 121, thus preventing the condensation from flowing into the mounting base 111 and damaging the fan 140.

[0144] Combination Figure 3 and Figure 7 As shown, in some embodiments, optionally, the base assembly 100 further includes: a retaining rib 180, the retaining rib 180 being disposed on the drip tray 170, the bottom of the retaining rib 180 being higher than the bottom of the receiving portion 120, and the retaining rib 180 being along the circumference of the steam generating assembly 130. Figure 7 (The arrow at point C points to) the distribution, and a third vent 181 is provided on the side of the rib 180 adjacent to the second vent 121. Steam in the cooking cavity 210 flows to the first gap 160 through the third vent 181.

[0145] A ring-shaped rib 180 is provided at the bottom of the drip tray 170. The rib 180 is distributed around the circumference of the steam generating assembly 130. The rib 180 extends into the receiving part 120, and the rib 180 encloses a relatively closed space within the receiving part 120.

[0146] A third opening is provided on the rim 180, which is adjacent to the air guide passage 171. The steam flowing back into the accommodating portion 120 flows to the air guide passage 171 through the third opening, and then flows into the first gap 160. The opening on the rim 180 is in such a manner that the steam flowing back into the accommodating portion 120 only flows outwards through the third opening, so that the steam can be discharged outwards by the fan 140, avoiding the steam flowing out of the gap between the shell 200 and the accommodating portion 120, thereby ensuring that the steam flowing outwards is subjected to cooling treatment, avoiding scalding the user.

[0147] Figure 7 In some embodiments, the solid arrows are used to represent the steam flow path, the dashed arrows are used to represent the cold air flow path, and the curved arrows are used to represent the cooled steam flow path.

[0148] In some embodiments, the juice tray 170 is optionally provided with a steam return port 172. The steam in the cooking cavity 210 is sucked into the fan 140 through the steam return port 172.

[0149] The steam in the cooking cavity 210 flows back into the accommodating portion 120 through the steam return port 172.

[0150] In combination Figure 3 and Figure 6 As shown in FIG. 1, in some embodiments, the accommodating portion 120 comprises a water tank body 124 and an air guide portion 125. The steam flowing back into the water tank body 124 exchanges heat with the water in the water tank body 124. The air guide portion 125 is provided on the top of the water tank body 124, and the second air hole 121 is provided in the air guide portion 125 adjacent to one side of the edge of the water tank body 124.

[0151] The second air hole 121 is provided on the air guide portion 125, which is located on one side of the air guide portion 125 away from the center of the water tank body 124. The path of the steam flowing to the second air hole 121 can be lengthened. The longer the steam flow path, the lower the steam temperature, thereby better achieving the steam cooling effect.

[0152] In combination Figure 1 and Figure 2 As shown in FIG. 1, in some embodiments of the present application, a cooking device is provided, which comprises a shell 200 and a base assembly 100 according to any one of the above embodiments, and can achieve the technical effects of any one of the above embodiments, which will not be repeated here.

[0153] The shell 200 is provided with a cooking cavity 210, and the shell 200 is provided on the base assembly 100.

[0154] In one possible application, the cooking device can be a steamer, an electric rice cooker, a steaming oven, etc.

[0155] As Figure 2As shown, the shell 200 comprises an outer shell 230, a partition 240 and a cover 220, the outer shell 230 is placed on the juice receiving disc 170, the cover 220 is arranged on the top wall of the outer shell 230, and the partition 240 is arranged in the outer shell 230. The number of partitions 240 can be multiple, and in an example embodiment, the number of partitions 240 in the embodiment is two, one partition 240 is placed above the juice receiving disc 170, and the other partition 240 is placed on the upper half of the outer shell 230, and the partition 240 is used to support food or tableware. In other embodiments, the number of partitions 240 can be increased to increase the number of layers of space for placing food.

[0156] In combination Figure 2 And Figure 5 As shown, in some embodiments, a steam return channel 300 is optionally arranged in the shell 200, one end of the steam return channel 300 extends towards the top of the shell 200, the other end of the steam return channel 300 communicates with the accommodating portion 120, and the steam in the cooking cavity 210 flows to the accommodating portion 120 through the steam return channel 300.

[0157] After the steam flows into the cooking cavity 210, the steam rises in the cooking cavity 210, and when the steam flows to the top of the cooking cavity 210, the steam flows into the steam return channel 300. In the case that a part of the steam flows to the top of the cooking cavity 210, the steam substantially fills the cooking cavity 210, so that the temperature of each part of the cooking cavity 210 is relatively high, thereby ensuring the uniform and hot effect of the steam on the food. The steam returns to the accommodating portion 120 through the steam return channel 300 for condensation, so that there is no need to arrange an opening for discharging steam on the shell 200, thereby avoiding scalding the user.
