Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, and more specifically, to a base assembly and a cooking equipment. Background Art

[0002] During the cooking process of cooking equipment, a large amount of high-temperature steam will be generated. Since the temperature of the kitchen cabinet is relatively low, when the high-temperature steam encounters the cabinet, condensed water will be generated on the cabinet, and users need to clean the condensed water on the cabinet, which brings inconvenience to the use of the cooking equipment by users. Summary of the Utility Model

[0003] The 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 utility model provides a base assembly for a cooking equipment. The cooking equipment has a cooking cavity, and the base assembly is used to fill steam into the cooking cavity. The base assembly includes: a base provided with an exhaust port; a water tank connected to the base, the water tank having an inner cavity, and the steam in the cooking cavity can flow back into the inner cavity; a fan connected to the base, and the fan is used to pump the steam flowing back into the inner cavity towards the exhaust port.

[0005] In the base assembly provided by the utility model, the steam generated in the water tank can be discharged into the cooking cavity, so as to heat the food materials in the cooking cavity.

[0006] As the amount of steam in the cooking cavity gradually increases, the steam in the cooking cavity can flow back into the inner cavity. Since there is water in the inner cavity, the steam flowing into the inner cavity can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The steam flows through the inner cavity and is discharged outwards through the exhaust port, that is, the steam whose temperature has been reduced through heat exchange in the inner cavity can be discharged from the cooking equipment. Since the temperature of the steam discharged from the cooking equipment is relatively low, users around the cooking equipment are not easily scalded by the steam, which is beneficial to improving the safety of users during the cooking process.

[0007] During the heat exchange process between the steam and the water in the inner cavity, the heat of the high-temperature steam will be transferred to the water, thereby realizing the recovery of the heat of the steam and avoiding waste of the heat of the steam. In addition, by heating the water with high-temperature steam, the temperature of the water can be increased, so that the water in the inner cavity can be quickly heated into steam, reducing the heating time of the steam generating component for the water, thereby reducing the energy consumption of the steam generating component and being beneficial to improving the energy utilization rate.

[0008] When the fan is operating, the fan is used to pump the steam that has flowed back into the inner cavity towards the exhaust port. Driven by the fan, the steam is discharged to the outside of the cooking device at a relatively high flow rate. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is relatively large, and the water molecules in the steam quickly mix with the air, making it difficult to form visible water droplets or condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules aggregating in a certain place, thus avoiding the formation of condensed water.

[0009] In addition, according to the base assembly in the above technical solution provided by the present invention, the following additional technical features may also be provided:

[0010] In some technical solutions, optionally, the rotational speed n of the fan satisfies n ≥ 1000 r / min.

[0011] In order to ensure that the steam discharged from the exhaust port can be quickly diffused, it is necessary to ensure that the fan has a relatively high rotational speed. In this solution, the rotational speed of the fan is limited to be greater than or equal to 1000 r / min to ensure that the steam is discharged to the outside of the cooking device at a relatively high flow rate.

[0012] In some technical solutions, optionally, the rotational speed n of the fan satisfies n ≤ 5000 r / min.

[0013] The greater the rotational speed of the fan, the better the diffusion effect of the steam. However, when the rotational speed of the fan is too high, the fan will generate relatively large noise. Therefore, in this solution, the rotational speed of the fan is limited to be less than or equal to 5000 r / min to avoid the generation of relatively large noise during the operation of the fan and reduce the noise during the operation of the cooking device.

[0014] In some technical solutions, optionally, the wind speed s at the air outlet of the fan satisfies s ≥ 1 m / s.

[0015] In order to ensure that the steam discharged from the exhaust port can be quickly diffused, it is necessary to ensure that the air outlet of the fan has a relatively high wind speed. In this solution, the wind speed s at the air outlet is limited to s ≥ 1 m / s to ensure that the steam is discharged to the outside of the cooking device at a relatively high flow rate.

[0016] In some technical solutions, optionally, the inner cavity is used for storing water, and the steam flowing back into the inner cavity is used to contact and exchange heat with the water in the inner cavity.

[0017] The steam flowing back into the inner cavity can contact the water, enabling the steam to directly exchange heat with the water, which is beneficial to improving the heat exchange efficiency of the steam and ensuring that the steam discharged from the cooking device has a relatively low temperature.

[0018] In some technical solutions, optionally, the base assembly further includes: a juice receiving tray connected to the water tank. The cooking cavity is located above the juice receiving tray. The juice receiving tray is provided with a steam inlet and a steam supply port. The steam inlet is used for the steam in the cooking cavity to flow back into the inner cavity, and the steam generated by the base assembly is used to be discharged into the cooking cavity through the steam supply port.

[0019] The water tank is used for storing water. The juice receiving tray is arranged at the opening position of the water tank, and an inner cavity is formed between the juice receiving tray and the water tank. After steam is generated in the water tank, the steam is discharged into the cooking cavity through the steam supply port on the juice receiving tray. Since the cooking cavity is located above the juice receiving tray, the steam discharged from the steam supply port directly enters the cooking cavity, thereby ensuring that high-temperature steam can quickly heat the food ingredients.

[0020] The cooking cavity is located above the juice receiving tray. During the cooking process, the juice receiving tray is used to receive and collect the juice flowing from the food ingredients, facilitating the user to centrally process the juice flowing from the food ingredients, which is beneficial to improving the convenience of use of the cooking device by the user. After using the juice receiving tray as the enclosing component of the inner cavity, there is no need to additionally set components cooperating with the water tank, which is beneficial to simplifying the structure of the cooking device.

[0021] In some technical solutions, optionally, the base assembly further includes: a guiding member located in the inner cavity. The guiding member is provided with a steam flow channel, the steam flow channel is communicated with the inner cavity, and the steam inlet is communicated with the steam flow channel.

[0022] The guiding member is provided with a steam flow channel, and the guiding member is used to guide the recovered steam so that the steam can flow along the guiding member. Under the guiding action of the guiding member, the steam exchanges heat with water along a set route, and the steam after heat exchange can flow to the outside of the cooking device.

[0023] In a possible application, a part of the guiding member is immersed in water, so that the water can exchange heat with the guiding member. In the case of steam flowing in the steam, the steam can indirectly exchange heat with the water through the guiding member.

[0024] Alternatively, an opening is provided at the bottom of the guiding member, so that the steam flow channel in the guiding member is in direct contact with the water, thereby enabling the steam to directly exchange heat with the water. A part of the guiding member is immersed in water, and the water plays a blocking role on the steam, ensuring that the steam can only flow in the steam flow channel and the steam is not easy to flow out of the steam flow channel, that is, it can ensure that the steam can stably exchange heat with the water and can also ensure that the steam flow channel can stably guide the steam.

[0025] In some technical solutions, optionally, the guiding member includes a bent guiding member, and the bent guiding member is used to form at least one bent section in the extending direction of the steam flow channel.

[0026] The longer the path of the steam flowing in the steam flow channel, the longer the heat exchange time between the steam and the water. Therefore, at least one bent section is formed on the steam flow channel, that is, the steam flow channel does not extend linearly, but a bent structure is formed on the steam flow channel. Forming a bent section on the steam flow channel can extend the length of the steam flow channel, thereby increasing the flow duration of the steam in the steam flow channel, increasing the heat exchange duration between the steam and the water, effectively reducing the temperature of the steam, and ensuring that the steam discharged from the cooking device is not likely to scald the user.

[0027] In some technical solutions, optionally, the top of the deflector is connected to the top wall of the inner cavity.

[0028] The top of the deflector is connected to the bottom of the inner cavity, so that there is no gap between the top of the deflector and the top of the inner cavity, preventing the steam from passing over the deflector from the top of the deflector, ensuring that the steam can only flow in the steam flow channel, and guaranteeing the heat exchange stability between the steam and the water.

[0029] In some technical solutions, optionally, the steam supply port and the steam flow channel are independent of each other.

[0030] The steam in the cooking cavity can flow into the steam flow channel. When the steam supply port and the steam flow channel are set to be independent of each other, the steam flowing back into the steam flow channel is not likely to be discharged into the cooking cavity again through the steam supply port, thus preventing the steam discharged into the cooking cavity from mixing with the steam flowing back into the steam flow channel, and ensuring the independence of the steam for heating and the steam for discharging outward.

[0031] In some technical solutions, optionally, the base assembly further includes: a partition member located in the inner cavity. The partition member is used to separate the steam flow channel and the steam supply port. A steam generation cavity is provided on the partition member, and the steam supply port is communicated with the steam generation cavity. The inner cavity is communicated with the steam generation cavity.

[0032] A partition member is provided in the inner cavity. The partition member can separate the steam supply port and the steam flow channel, making it difficult for the steam flowing to the steam supply port and the steam in the steam flow channel to mix with each other. Therefore, the steam generated by the heated water is not likely to flow into the steam flow channel, and the steam flowing back into the steam flow channel is not likely to be discharged into the cooking cavity again, ensuring that the steam flowing into the cooking cavity and the steam flowing back into the steam flow channel are two parts of steam that are approximately independent of each other, thereby ensuring that the steam discharged into the cooking cavity has a relatively high temperature and guaranteeing the heating effect on the food ingredients.

[0033] A steam generation chamber is provided inside the partition member. The steam generation chamber is in communication with the steam supply port. When the water inside the steam generation chamber is heated, steam is generated. The steam inside the steam generation chamber is discharged into the cooking chamber through the steam supply port. The partition member can define a steam generation chamber with a small amount of stored water. Therefore, the small amount of water inside the steam generation chamber can be quickly heated into steam, which is beneficial to improving the steam generation speed and thus beneficial to enhancing the heating effect on the food ingredients.

[0034] An inlet hole is provided on the partition member. The inlet hole is used to communicate the steam generation chamber and the inner cavity. The water in the inner cavity can be injected into the steam generation chamber through the inlet hole. When the water in the steam generation chamber is heated into steam, the water in the inner cavity replenishes the steam generation chamber through the inlet hole to prevent the water in the steam generation chamber from being burned dry. According to the principle of communicating vessels, the liquid level height in the steam generation chamber is basically the same as that in the inner cavity, thus ensuring that there is a small amount of water in the steam generation chamber.

[0035] In some technical solutions, optionally, the water tank is provided with a gas guide hole. The steam flow channel and the exhaust port are connected through the gas guide hole; wherein, the opening area of the gas guide hole is greater than or equal to 50 mm 2 ; and / or the opening area of the exhaust port is greater than or equal to 50 mm 2 .

[0036] To ensure that the steam can be quickly discharged from the cooking device, it is necessary to ensure that the gas guide hole and the exhaust port have a large opening area. In this solution, it is defined that the opening area of the gas guide hole and / or the exhaust port is greater than or equal to 50 mm 2 , ensuring that the steam can be discharged smoothly, which is beneficial to making the steam form droplets or condensed water that are difficult to see.

[0037] In some technical solutions, optionally, the water tank includes a gas guide part. The side of the gas guide part is provided with a gas guide hole, and the gas guide part is located above the fan.

[0038] The gas guide part is used to divert the steam to the fan. The gas guide part is arranged above the fan, that is, the height of the gas guide part is relatively high, and the water in the inner cavity is not easily introduced into the gas guide part, preventing the water from contacting the fan.

[0039] In some technical solutions, optionally, the base is provided with an installation cavity, and the fan is located inside the installation cavity.

[0040] An installation cavity is provided on the base. The installation cavity is used to install the fan. The installation cavity is used to communicate the steam flow channel and the exhaust port. By arranging the fan inside the installation cavity, the air flow flowing into the installation cavity basically comes from the steam flow channel, and the fan is not easily able to extract the air inside the base, thus ensuring that the steam in the steam flow channel is discharged at a relatively high flow rate, further preventing the steam discharged from the cooking device from forming condensed water.

[0041] In some technical solutions, optionally, the exhaust port is provided on the side of the base.

[0042] The exhaust port discharges from the side of the base. When the base is placed on the workbench, it is not easy for the workbench to block the exhaust port, ensuring stable discharge of steam.

[0043] In some technical solutions, optionally, a recessed portion is provided on the base, and the exhaust port is provided on the inner wall of the recessed portion.

[0044] By arranging the exhaust port on the recessed portion, it is not easy for users to touch the exhaust port, avoiding the user accidentally touching the exhaust port and being scalded by high-temperature steam.

[0045] In a second aspect, the present utility model proposes a cooking device, including the base assembly as in the first aspect.

[0046] In some technical solutions, optionally, the cooking device further includes: a steamer assembly, and the steamer assembly has a cooking cavity.

[0047] In some technical solutions, optionally, the steamer assembly includes: a steamer, provided on the base assembly; a cover body, covering the steamer to form a closed space inside the cover body and the steamer.

[0048] The food ingredients can be placed in the steamer, and the space inside the cover body and the steamer is the cooking cavity. When the cover body covers the steamer, the inside of the cover body and the steamer is in a closed state, that is, no air holes for exhausting are provided on the cover body, so that the gas in the cooking cavity will not be discharged outward through the cover body, thereby ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged outward.

Detailed implementation manners

[0060] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0061] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0062] The following refers to Figures 1 to 7 Describe the base assembly and cooking device provided according to some embodiments of the present utility model.

[0063] In combination with Figure 2 and Figure 3As shown, in some embodiments of the present utility model, a base assembly 100 is proposed. The base assembly 100 is for a cooking device. The cooking device has a cooking cavity 210. The base assembly 100 is used to fill steam into the cooking cavity 210. The base assembly 100 includes: a base 110, a water tank 120, and a blower 130. An exhaust port 111 is provided on the base 110. The water tank 120 is connected to the base 110. The water tank 120 has an inner cavity 121. The steam in the cooking cavity 210 can flow back into the inner cavity 121. The blower 130 is connected to the base 110. The blower 130 is used to pump the steam flowing back into the inner cavity 121 towards the exhaust port 111.

[0064] In the base assembly 100 provided in this embodiment, the steam generated in the water tank 120 can be discharged into the cooking cavity 210, so as to heat the food materials in the cooking cavity 210.

[0065] As the amount of steam in the cooking cavity 210 gradually increases, the steam in the cooking cavity 210 can flow back into the inner cavity 121. Since there is water in the inner cavity 121, the steam flowing into the inner cavity 121 can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The steam flows through the inner cavity 121 and is discharged outward through the exhaust port 111. That is, the steam whose temperature has been reduced by heat exchange in the inner cavity 121 can be discharged from the cooking device. Since the temperature of the steam discharged from the cooking device is relatively low, the users around the cooking device are not easily scalded by the steam, which is beneficial to improving the safety of users during the cooking process.

[0066] Figure 2 The arrows inside the cooking device are used to indicate the steam flow direction.

[0067] During the heat exchange process between the steam and the water in the inner cavity 121, the heat of the high-temperature steam will be transferred to the water, thereby realizing the recovery of the heat of the steam and avoiding waste of the heat of the steam. Moreover, by heating the water with the high-temperature steam, the temperature of the water can be increased, so that the water in the inner cavity 121 can be quickly heated into steam, reducing the heating time of the water by the steam generating assembly, thereby reducing the energy consumption of the steam generating assembly and being beneficial to improving the energy utilization rate.

[0068] When the blower 130 is operating, the blower 130 is used to pump the steam flowing back into the inner cavity 121 towards the exhaust port 111. Driven by the blower 130, the steam is discharged to the outside of the cooking device at a relatively high flow rate. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is relatively large. The water molecules in the steam quickly mix with the air and it is difficult to form visible water droplets or condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules aggregating at a certain place, thereby avoiding the formation of condensed water.

[0069] In some embodiments, optionally, the rotational speed n of the blower 130 satisfies n ≥ 1000 r / min.

[0070] To ensure that the steam discharged from the exhaust port 111 can diffuse quickly, it is necessary to ensure that the blower 130 has a relatively high rotational speed. In this solution, the rotational speed of the blower 130 is limited to be greater than or equal to 1000 r / min to ensure that the steam is discharged to the outside of the cooking device at a relatively high flow rate.

[0071] In some embodiments, optionally, the rotational speed n of the blower 130 satisfies n ≤ 5000 r / min.

[0072] The greater the rotational speed of the blower 130, the better the diffusion effect of the steam. However, when the rotational speed of the blower 130 is too high, the blower 130 will generate a relatively large noise. Therefore, in this solution, the rotational speed of the blower 130 is limited to be less than or equal to 5000 r / min to avoid generating a relatively large noise during the operation of the blower 130 and reduce the noise during the operation of the cooking device.

[0073] In some embodiments, optionally, the wind speed s at the air outlet of the blower 130 satisfies s ≥ 1 m / s.

[0074] To ensure that the steam discharged from the exhaust port 111 can diffuse quickly, it is necessary to ensure that the air outlet of the blower 130 has a relatively high wind speed. In this solution, the wind speed s at the air outlet is limited to s ≥ 1 m / s to ensure that the steam is discharged to the outside of the cooking device at a relatively high flow rate.

[0075] Combined with Figure 2 and Figure 3 As shown, in some embodiments, optionally, the inner cavity 121 is used for storing water, and the steam that returns to the inner cavity 121 is used for heat exchange by contacting the water in the inner cavity 121.

[0076] The steam that returns to the inner cavity 121 can contact the water, enabling the steam to directly exchange heat with the water, which is beneficial to improving the heat exchange efficiency of the steam and ensuring that the steam discharged from the cooking device has a relatively low temperature.

[0077] Combined with Figure 2 and Figure 4 As shown, in some embodiments, optionally, the base assembly 100 further includes: a juice receiving tray 140, which is provided on the water tank 120. The cooking cavity 210 is located above the juice receiving tray 140. The juice receiving tray 140 is provided with a steam inlet 141 and a steam supply port 142. The steam inlet 141 is used for the steam in the cooking cavity 210 to return to the inner cavity 121, and the steam generated by the base assembly 100 is used to be discharged into the cooking cavity 210 through the steam supply port 142.

[0078] The water tank 120 is used for storing water. The juice receiving tray 140 is arranged at the opening position of the water tank 120. An inner cavity 121 is formed between the juice receiving tray 140 and the water tank 120. After steam is generated in the water tank 120, the steam is discharged into the cooking cavity 210 through the steam supply port 142 on the juice receiving tray 140. Since the cooking cavity 210 is located above the juice receiving tray 140, the steam discharged from the steam supply port 142 directly enters the cooking cavity 210, so as to ensure that the high-temperature steam can quickly heat the food materials.

[0079] The cooking cavity 210 is located above the juice receiving tray 140. During the cooking process, the juice receiving tray 140 is used for receiving and collecting the juice flowing down from the food materials, which is convenient for the user to centrally process the juice flowing down from the food materials and is beneficial to improving the use convenience of the cooking equipment by the user. After using the juice receiving tray 140 as the enclosing component of the inner cavity 121, there is no need to additionally set components cooperating with the water tank 120, which is beneficial to simplifying the structure of the cooking equipment.

[0080] In a possible application, the juice receiving tray 140 is directly placed on the water tank 120 so as to facilitate the user to take the juice receiving tray 140 to pour out the juice.

[0081] In this embodiment, the juice receiving tray 140 is used as a part of the water tank 120, and the inner cavity 121 is formed by enclosing between the water tank 120 and the juice receiving tray 140. In other embodiments, the water tank 120 can also be set to independently form the inner cavity 121.

[0082] Combined with Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown in, in some embodiments, optionally, the base assembly 100 further includes: a flow guiding member 150. The flow guiding member 150 is located in the inner cavity 121. A steam flow channel 151 is provided on the flow guiding member 150. The steam flow channel 151 is communicated with the inner cavity 121, and the steam inlet 141 is communicated with the steam flow channel 151.

[0083] Figure 6 In, the arrow direction in the steam flow channel 151 is used to represent the steam flow direction.

[0084] The steam flow channel 151 is provided on the flow guiding member 150. The flow guiding member 150 is used for guiding the recovered steam so that the steam can flow along the flow guiding member 150. Under the guiding action of the flow guiding member 150, the steam exchanges heat with water along a set route, and the heat-exchanged steam can flow to the outside of the cooking equipment.

[0085] In a possible application, a part of the flow guiding member 150 is immersed in water, so that the water can exchange heat with the flow guiding member 150. In the case of steam flowing in the steam, the steam can indirectly exchange heat with the water through the flow guiding member 150.

[0086] Alternatively, an opening is provided at the bottom of the flow guide member 150, so that the steam flow path 151 in the flow guide member 150 is in direct contact with water, thereby enabling direct heat exchange between the steam and the water. A part of the flow guide member 150 is immersed in water, and the water acts as a barrier to the steam, ensuring that the steam can only flow within the steam flow path 151 and is not likely to flow out of the steam flow path 151. That is, it can ensure stable heat exchange between the steam and the water and also ensure that the steam flow path 151 can stably guide the steam.

[0087] In a possible application, the flow guide member 150 is connected to the juice receiving tray 140.

[0088] As Figure 6 shown, in some embodiments, optionally, the flow guide member 150 includes a bent flow guide member for forming at least one bent section 152 in the extending direction of the steam flow path 151.

[0089] The longer the path of the steam flowing in the steam flow path 151, the longer the heat exchange time between the steam and the water. Therefore, at least one bent section 152 is formed on the steam flow path 151, that is, the steam flow path 151 does not extend linearly but forms a bent structure on the steam flow path 151. The formation of the bent section 152 on the steam flow path 151 can extend the length of the steam flow path 151, thereby increasing the flow duration of the steam in the steam flow path 151, increasing the heat exchange duration between the steam and the water, effectively reducing the temperature of the steam, and ensuring that the steam discharged from the cooking device is not likely to scald the user.

[0090] Combined with Figure 2 、 Figure 4 and Figure 5 shown, in some embodiments, optionally, the top of the flow guide member 150 is connected to the top wall of the inner cavity 121.

[0091] The top of the flow guide member 150 is connected to the bottom of the inner cavity 121, so that there is no gap between the top of the flow guide member 150 and the top of the inner cavity 121, preventing the steam from passing over the flow guide member 150 from the top of the flow guide member 150, ensuring that the steam can only flow within the steam flow path 151 and guaranteeing the heat exchange stability between the steam and the water.

[0092] In some embodiments, optionally, the steam supply port 142 and the steam flow path 151 are independent of each other.

[0093] The steam in the cooking cavity 210 can flow to the steam flow channel 151. When the steam supply port 142 and the steam flow channel 151 are set to be independent of each other, the steam flowing back into the steam flow channel 151 is not likely to be discharged again into the cooking cavity 210 through the steam supply port 142, thereby avoiding the mixing of the steam discharged into the cooking cavity 210 and the steam flowing back into the steam flow channel 151, and ensuring the independence of the steam for heating and the steam for discharging outward.

[0094] Combined with Figure 2 and Figure 7 As shown, in some embodiments, optionally, the base assembly 100 further includes: a separator 160. The separator 160 is located in the inner cavity 121. The separator 160 is used to separate the steam flow channel 151 and the steam supply port 142. A steam generation cavity 161 is provided on the separator 160. The steam supply port 142 is communicated with the steam generation cavity 161. The inner cavity 121 is communicated with the steam generation cavity 161.

[0095] A separator 160 is provided in the inner cavity 121. The separator 160 can separate the steam supply port 142 and the steam flow channel 151, so that the steam flowing to the steam supply port 142 and the steam in the steam flow channel 151 are not likely to mix with each other. Therefore, the steam generated by heating water is not likely to flow to the steam flow channel 151, and the steam flowing back into the steam flow channel 151 is not likely to be discharged into the cooking cavity 210 again, ensuring that the steam flowing to the cooking cavity 210 and the steam flowing back into the steam flow channel 151 are two parts of steam that are nearly independent of each other, thereby ensuring that the steam discharged into the cooking cavity 210 has a relatively high temperature and ensuring the heating effect on the food ingredients.

[0096] A steam generation cavity 161 is provided in the separator 160. The steam generation cavity 161 is communicated with the steam supply port 142. The water in the steam generation cavity 161 will generate steam after being heated. The steam in the steam generation cavity 161 is discharged into the cooking cavity 210 through the steam supply port 142. The separator 160 can define a steam generation cavity 161. The amount of water stored in the steam generation cavity 161 is small. Therefore, the small amount of water in the steam generation cavity 161 can be quickly heated into steam, which is beneficial to improving the steam generation speed and further beneficial to improving the heating effect on the food ingredients.

[0097] The water inlet hole 162 is provided on the partition member 160. The water inlet hole 162 is used to communicate the steam generation cavity 161 and the inner cavity 121. The water in the inner cavity 121 can be injected into the steam generation cavity 161 through the water inlet hole 162. When the water in the steam generation cavity 161 is heated into steam, the water in the inner cavity 121 is replenished into the steam generation cavity 161 through the water inlet hole 162, preventing the water in the steam generation cavity 161 from being dried up. According to the principle of communicating vessels, the liquid level height in the steam generation cavity 161 is basically the same as the liquid level height in the inner cavity 121, thus ensuring that a small amount of water is maintained in the steam generation cavity 161.

[0098] In a possible application, the partition member 160 is directly placed in the water tank 120, or the partition member 160 is connected to the water tank 120.

[0099] The base assembly 100 further includes a heater 170. The heater 170 is used to heat the water in the steam generation cavity 161 to generate steam. Alternatively, the base assembly 100 includes a steam generator that supplies steam into the steam generation cavity 161.

[0100] Combined Figure 2 and Figure 3 As shown, in some embodiments, optionally, the water tank 120 is provided with a gas guide hole 122. The steam flow channel 151 and the exhaust port 111 are connected through the gas guide hole 122; wherein, the opening area of the gas guide hole 122 is greater than or equal to 50 mm 2 ; and / or the opening area of the exhaust port 111 is greater than or equal to 50 mm 2 .

[0101] To ensure that the steam can be quickly discharged from the cooking device, it is necessary to ensure that the gas guide hole 122 and the exhaust port 111 have a large opening area. In this solution, it is defined that the opening area of the gas guide hole 122 and / or the exhaust port 111 is greater than or equal to 50 mm 2 , ensuring that the steam can be discharged smoothly, which is beneficial for the steam to form water droplets or condensed water that are difficult to see.

[0102] Combined Figure 2 and Figure 3 As shown, in some embodiments, optionally, the water tank 120 includes a gas guide portion 123. The side portion of the gas guide portion 123 is provided with a gas guide hole 122, and the gas guide portion 123 is located above the blower 130.

[0103] The gas guide portion 123 is used to guide the steam to the blower 130. The gas guide portion 123 is arranged above the blower 130, that is, the height of the gas guide portion 123 is relatively high, and the water in the inner cavity 121 is not easily introduced into the gas guide portion 123, preventing the water from contacting the blower 130.

[0104] As Figure 2As shown, in some embodiments, optionally, an installation cavity 112 is provided on the base 110, and the fan 130 is located within the installation cavity 112.

[0105] An installation cavity 112 is provided on the base 110. The installation cavity 112 is for installing the fan 130 and is used to connect the steam flow channel 151 and the exhaust port 111. By arranging the fan 130 within the installation cavity 112, the air flow flowing into the installation cavity 112 basically comes from the steam flow channel 151, and it is not easy for the fan 130 to extract the air inside the base 110, thereby ensuring that the steam in the steam flow channel 151 is discharged at a relatively high flow rate, further avoiding the formation of condensate from the steam discharged from the cooking device.

[0106] As Figure 3 shown, in some embodiments, optionally, the exhaust port 111 is provided on the side of the base 110.

[0107] The exhaust port 111 discharges from the side of the base 110. When the base 110 is placed on the workbench surface, it is not easy for the workbench surface to block the exhaust port 111, ensuring stable steam discharge.

[0108] As Figure 3 shown, in some embodiments, optionally, a recessed portion 113 is provided on the base 110, and the exhaust port 111 is provided on the inner wall of the recessed portion 113.

[0109] By arranging the exhaust port 111 on the recessed portion 113, it is not easy for users to touch the exhaust port 111, avoiding users accidentally touching the exhaust port 111 and being scalded by high-temperature steam.

[0110] In the embodiments of the present utility model, a cooking device is proposed, which includes the base assembly 100 in any of the above embodiments and can achieve the same technical effects, and will not be elaborated here.

[0111] In some embodiments, optionally, the cooking device further includes: a steamer assembly 200, provided on the base assembly 100. The steamer assembly 200 has a cooking cavity 210, and both the steam supply port 142 and the steam inlet 141 are connected to the cooking cavity 210.

[0112] The steamer assembly 200 can be placed on the water tank 120 or on the base 110, and steam is discharged into the steamer assembly 200 through the steam supply port 142.

[0113] Combined with Figure 1 、 Figure 2 and Figure 4As shown, the steam generated by the steam generating assembly is discharged into the cooking cavity 210 through the steam supply port 142. However, the steam supply port 142 and the steam inlet 141 are both arranged on the juice receiving tray 140. In order to prevent the steam discharged from the steam supply port 142 into the cooking cavity 210 from directly flowing to the steam inlet 141, a steam return pipe 300 is installed on the steam inlet 141.

[0114] One end of the steam return pipe 300 is connected to the steam inlet 141, and the other end of the steam return pipe 300 extends to the top of the cooking cavity 210. After the steam flows into the cooking cavity 210 through the steam supply port 142, the steam rises in the cooking cavity 210. Since the height of the steam return pipe 300 is relatively high, the steam will flow into the steam return pipe 300 only when the steam flows to the top of the cooking cavity 210. Therefore, when a part of the steam flows to the top of the cooking cavity 210, the steam basically fills the cooking cavity 210, so that the temperature of each place in the cooking cavity 210 is relatively high, ensuring the uniform heating effect of the steam on the food.

[0115] By installing the steam reflux pipe 300 on the steam inlet 141, the steam is not likely to flow directly to the steam inlet 141, thereby ensuring that the steam can effectively heat the food.

[0116] In some embodiments, optionally, the steamer assembly 200 includes: a steamer 220 and a cover 230 , the steamer 220 is disposed on the base assembly 100 , and the cover 230 is covered on the steamer 220 , so that a closed space is formed in the cover 230 and the steamer 220 .

[0117] The food can be placed in the steamer 220, and the space between the cover 230 and the steamer 220 is the cooking cavity 210. When the cover 230 is covered in the steamer 220, the cover 230 and the steamer 220 are in a closed state, that is, the cover 230 is not provided with air holes for exhaust, so that the gas in the cooking cavity 210 will not be discharged to the outside through the cover 230, thereby ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged to the outside.
