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, a large amount of high-temperature steam will be generated by cooking equipment. When the high-temperature steam is discharged into the indoor space, users are easily scalded by the high-temperature steam, resulting in poor safety during the cooking process. 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. The base assembly includes: a base, on which an installation cavity is provided. The installation cavity has an exhaust port and a gas supplement port, and the gas supplement port is communicated with the exhaust port; a steam generating assembly, connected to the base. The steam generating assembly is provided with a steam inlet, a steam supply port and an inner cavity. A steam flow channel is arranged in the inner cavity. The steam inlet is communicated with the steam flow channel. The steam generated by the steam generating assembly is used to be discharged into the cooking cavity through the steam supply port. The steam inlet is used to supply the steam in the cooking cavity to flow back into the steam flow channel; a fan, located in the installation cavity, and the fan is used to drive the steam flowing back into the steam flow channel to be discharged from the exhaust port.

[0005] In the base assembly provided by the utility model, the steam generating assembly is arranged on the base. When the steam generating assembly operates, the steam generating assembly heats the water in the inner cavity, so that the steam generating assembly can generate steam. The steam generating assembly is provided with a steam supply port, and the steam generated by the steam generating assembly can be discharged into the cooking cavity through the steam supply port, so as to heat the food materials in the cooking cavity.

[0006] A steam flow channel is arranged in the inner cavity. The steam can heat the food materials in the cooking cavity. As the amount of steam in the cooking cavity gradually increases, the steam in the cooking cavity can flow into the steam flow channel from the steam inlet. Since there is water in the inner cavity, the steam flowing into the steam flow channel can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The exhaust port is communicated with the outside of the cooking equipment, and the steam flows through the steam flow channel and is discharged outward through the exhaust port. That is, the steam in the steam flow channel whose temperature has been reduced by heat exchange can be discharged from the cooking equipment. Since the temperature of the steam discharged from the cooking equipment is relatively low, the 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] Moreover, during the heat exchange process between the steam and the water in the inner cavity, the heat of the high-temperature steam is transferred to the water, thereby realizing the recovery of the steam heat and avoiding waste of the steam heat. 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 water by the steam generating component, thereby reducing the energy consumption of the steam generating component and being conducive to improving the energy utilization rate.

[0008] When the fan operates, the fan is used to pump the steam in the steam flow channel 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 somewhere, thus avoiding the formation of condensed water.

[0009] An installation cavity is provided on the base. The installation cavity is used to install the fan, and the installation cavity is used to connect the steam outlet and the exhaust port. By arranging the fan in the installation cavity, the air flow flowing into the installation cavity basically comes from the steam outlet, and it is not easy for the fan to pump out the air inside the base, so as to ensure that the steam in the steam flow channel is discharged at a relatively high flow rate, further avoiding the formation of condensed water in the steam discharged from the cooking device.

[0010] After the steam discharged from the steam flow channel and the external gas replenished through the air replenishing hole are mixed, the mixed gas is discharged through the steam outlet. The purpose of setting the air replenishing hole is to increase the air flow rate, reduce the temperature of the discharged steam, and at the same time, it can reduce the negative pressure at the steam outlet, avoid the steam in the steam flow channel from being discharged too fast, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0011] 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 included:

[0012] In some technical solutions, optionally, the exhaust port and the air replenishing port are provided on different walls of the base.

[0013] Both the exhaust port and the air replenishing port are provided on the base. However, the exhaust port and the air replenishing port need to be provided on different walls of the base. The exhaust port is used to discharge steam to the outside, and the air replenishing port is used to allow the external normal-temperature gas to flow into the installation cavity. By setting the exhaust port and the air replenishing port on different walls of the base, it can effectively prevent the exhaust of the exhaust port from interfering with the intake of the air replenishing port, avoid the just-discharged steam from being inhaled into the installation cavity through the air replenishing port, and ensure that the temperature of the air flow inhaled into the installation cavity through the exhaust is relatively low, thereby being conducive to cooling the discharged steam.

[0014] In some technical solutions, optionally, the exhaust port and the air supplement port are provided on adjacent wall surfaces of the base.

[0015] Setting the exhaust port and the air supplement port on different wall surfaces of the base can effectively avoid the interference between the exhaust of the exhaust port and the intake of the air supplement port. In this case, the exhaust port and the air supplement port can be provided on adjacent wall surfaces of the base. The fan usually has an axial intake and a side exhaust. When the exhaust port and the air supplement port are located on adjacent wall surfaces, the air supplement port can correspond to the intake part of the fan, and the exhaust port can correspond to the exhaust part of the fan, which is beneficial to increasing the intake air flow rate, thereby effectively reducing the temperature of the steam and avoiding scalding the user.

[0016] In some technical solutions, optionally, the exhaust port is provided on one side wall of the base, and the air supplement port is provided on the side wall and / or the bottom wall of the base.

[0017] When the exhaust port is provided on the side wall of the base, the air supplement port can also be provided on the side wall of the base, but the exhaust port and the air supplement port are provided on different side walls of the base. Or, when the exhaust port is provided on the side wall of the base, the air supplement port can be provided on the bottom wall of the base.

[0018] In some technical solutions, optionally, the base is provided with feet, and the air supplement port is higher than the bottom of the feet.

[0019] The base is provided with feet for supporting the base. The feet can raise the base, and when the feet are placed on the workbench surface, there is a space between the base and the workbench surface. When the air supplement port is provided on the bottom wall of the base, there is a gap between the air supplement port and the workbench surface, and the workbench surface does not block the air supplement port, so as to ensure that external gas can smoothly flow into the installation cavity through the air supplement port.

[0020] In some technical solutions, optionally, there is an arc transition part between the side wall and the bottom wall of the base, and the air supplement port is provided on the arc transition part.

[0021] The side wall and the bottom wall of the base are connected by an arc transition part. The arc transition part is an arc-shaped structure, so that the side wall and the bottom wall of the base are smoothly transitioned. The arc transition part bends upward compared with the bottom wall. When the air supplement port is provided on the arc transition part, at least a part of the air supplement port is higher than the bottom wall. Even if the base is closely attached to the workbench surface, the air supplement port will not be blocked by the workbench surface, so as to ensure that external gas can smoothly flow into the installation cavity through the air supplement port.

[0022] In some technical solutions, optionally, the opening area of the air supplement port is greater than or equal to the opening area of the exhaust port.

[0023] The opening area of the air inlet is equal to the opening area of the air outlet, or the opening area of the air inlet is larger than the opening area of the air outlet, so that the air inlet can supply sufficient air into the installation cavity, effectively reducing the negative pressure at the steam outlet.

[0024] In some technical solutions, optionally, the base is provided with a recess, and the air outlet is arranged on the inner wall of the recess.

[0025] A recess is formed on the base by machining, and the recess is recessed into the interior of the base. When the air outlet is arranged on the inner wall of the recess, it is not easy for users to touch the air outlet. The steam just discharged through the air outlet still has a relatively high temperature. If the user directly leans against the vicinity of the air outlet, they may be scalded by the high-temperature steam discharged from the air outlet. Therefore, when the air outlet is arranged in the recess, it is not easy for users to directly touch the air outlet, thereby reducing the risk of the user being scalded by the steam.

[0026] In some technical solutions, optionally, the wind speed s at the air outlet of the fan satisfies s ≥ 1 m / s.

[0027] The fan has an air outlet, and the airflow blown by the fan is discharged from the air outlet of the fan. When the wind speed at the air outlet is greater than or equal to 1 m / s, it is beneficial to the rapid flow and diffusion of the steam, so that it is difficult to form visible water droplets or condensed water.

[0028] In some technical solutions, optionally, the steam generating assembly includes: a water tank; a juice collecting tray connected to the water tank, with an inner cavity located between the juice collecting tray and the water tank, a cooking cavity located above the juice collecting tray, and a steam inlet and a steam supply port provided on the juice collecting tray.

[0029] The water tank is used for storing water. The juice collecting tray is arranged at the opening position of the water tank, and an inner cavity is formed between the juice collecting tray and the water tank. When the steam generating assembly operates, the water in the water tank is heated, and after steam is generated in the water tank, the steam is discharged into the cooking cavity through the steam supply port on the juice collecting tray. Since the cooking cavity is located above the juice collecting tray, the steam discharged from the steam supply port directly enters the cooking cavity, thereby ensuring that the high-temperature steam can quickly heat the food ingredients.

[0030] The cooking cavity is located above the juice collecting tray. During the cooking process, the juice collecting tray is used to receive and collect the juice flowing down from the food ingredients, facilitating the user to centrally process the juice flowing down from the food ingredients, which is beneficial to improving the convenience of use of the cooking equipment by the user. After using the juice collecting 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 equipment.

[0031] In some technical solutions, optionally, the steam generating assembly further includes: a guiding member connected to the juice collecting tray, and a steam flow channel is provided on the guiding member.

[0032] The deflector is provided with a steam flow channel. The deflector is used to direct the recovered steam so that the steam can flow along the deflector. Under the guiding action of the deflector, 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.

[0033] A part of the deflector is immersed in water, so that the water can exchange heat with the deflector. In the case of steam flowing in the steam, the steam can indirectly exchange heat with the water through the deflector.

[0034] Alternatively, an opening is provided at the bottom of the deflector, so that the steam flow channel in the deflector is in direct contact with the water, so that the steam directly exchanges heat with the water. A part of the deflector 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 it can also ensure that the steam flow channel can stably guide the steam.

[0035] In some technical solutions, optionally, the water tank is provided with a vent hole, and the steam flow channel and the installation cavity are connected through the vent hole, and the opening area of the vent hole is less than or equal to the opening area of the exhaust port.

[0036] The opening area of the vent hole is equal to the opening area of the exhaust port, or the opening area of the vent hole is less than the opening area of the exhaust port, which can prevent the steam in the cooking cavity from being discharged outwards too quickly, and promote the full action of the steam and the fan, which is beneficial to promoting the diffusion of the steam and reducing the formation of condensed water in the air.

[0037] In some technical solutions, optionally, the opening area of the vent hole is greater than or equal to 50mm 2 ; and / or the opening area of the exhaust port is greater than or equal to 50mm 2 .

[0038] When the opening areas of the vent hole and the exhaust port meet the above ranges, it can ensure that the steam can be smoothly discharged from the steam flow channel and prevent the steam from accumulating excessively in the steam flow channel.

[0039] In some technical solutions, optionally, the vent hole is located at the top of the installation cavity.

[0040] The vent hole is arranged at the upper part of the installation cavity, so that the vent hole has a relatively high position, and the water in the steam flow channel is not easy to enter the vent hole, thus preventing the steam from carrying the water in the steam flow channel out. Moreover, the above setting method can promote the diffusion of the steam in the installation cavity, enable the steam to fully act with the fan, and promote the diffusion of the steam in the air.

[0041] In some technical solutions, optionally, the vent hole is located at the top of the fan.

[0042] The air vent is arranged above the blower, and the distance between the air vent and the blower is small, which is conducive to the blower quickly extracting the steam from the air vent.

[0043] In some technical solutions, optionally, the air vent is located outside the installation cavity.

[0044] The air vent extends out of the installation cavity. Even if a small amount of water comes into contact with the air vent, it is not easy for the small amount of water to enter the installation cavity, thus preventing the water in the steam water tank from entering the installation cavity.

[0045] In some technical solutions, optionally, the steam generating assembly further includes: a partition member located in the inner cavity. The partition member is used to separate the steam supply port and the steam flow path. A steam generating cavity is provided on the partition member, and the steam generating cavity is communicated with the inner cavity, and the steam supply port is communicated with the steam generating cavity.

[0046] A partition member is arranged in the inner cavity. The partition member can separate the steam supply port and the steam flow path, so that the steam flowing towards the steam supply port and the steam in the steam flow path are not easily mixed with each other. Therefore, the steam generated by the heated water is not easily directed to the steam flow path, and the steam flowing back into the steam flow path is not easily discharged into the cooking cavity again, ensuring that the steam flowing towards the cooking cavity and the steam flowing back into the steam flow path 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 ensuring the heating effect on the food ingredients.

[0047] A steam generating cavity is arranged in the partition member. The steam generating cavity is communicated with the steam supply port. The water in the steam generating cavity is heated to generate steam, and the steam in the steam generating cavity is discharged into the cooking cavity through the steam supply port. The partition member can define a steam generating cavity, and the amount of water stored in the steam generating cavity is small. Therefore, the small amount of water in the steam generating cavity can be quickly heated into steam, which is conducive to improving the steam generation speed and further conducive to improving the heating effect on the food ingredients.

[0048] An inlet hole is arranged on the partition member. The inlet hole is used to communicate the steam generating cavity and the inner cavity, and the water in the inner cavity can be injected into the steam generating cavity through the inlet hole. When the water in the steam generating cavity is heated into steam, the water in the inner cavity is replenished into the steam generating cavity through the inlet hole to prevent the water in the steam generating cavity from being burned dry. According to the principle of communicating vessels, the liquid level height in the steam generating cavity is basically the same as the liquid level height in the inner cavity, thereby ensuring that a small amount of water is maintained in the steam generating cavity.

[0049] In some technical solutions, optionally, the steam generating assembly further includes: a heating member connected to the base, and the heating member is disposed opposite to the steam generating cavity.

[0050] The heating member faces the steam generating cavity, so that the heating member can only heat the water in the steam generating cavity, which is conducive to improving the steam generation speed.

[0051] In some technical solutions, optionally, the top of the separator is hermetically arranged with the juice receiving tray.

[0052] The top of the separator is hermetically arranged with the juice receiving tray, so that there is no gap between the top of the separator and the juice receiving tray, preventing steam from passing over the separator at the top of the separator, thereby preventing the steam flowing back into the steam flow channel from mixing with the newly generated steam in the steam generation cavity.

[0053] In a second aspect, the present utility model proposes a cooking device, including the base assembly as in the first aspect.

[0054] In some technical solutions, optionally, the cooking device further includes: a steamer assembly, the steamer assembly having a cooking cavity, and a steam supply port and a steam inlet are both connected to the cooking cavity.

[0055] In some technical solutions, optionally, the steamer assembly includes: a steamer disposed on the base assembly; a cover covering the steamer to form a closed space inside the cover and the steamer.

[0056] Food ingredients can be placed in the steamer, and the space inside the cover and the steamer is the cooking cavity. When the cover is covered inside the steamer, the inside of the cover and the steamer is in a closed state, that is, there are no air holes for exhaust provided on the cover, so that the gas in the cooking cavity will not be discharged outward through the cover, 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

[0070] 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 can be combined with each other.

[0071] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can 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.

[0072] The following refers to Figures 1 to 9 Describe the base assembly and cooking equipment provided according to some embodiments of the present utility model.

[0073] Combined with Figure 2 , Figure 4 , Figure 5 And Figure 8As shown, in an embodiment of the present utility model, a base assembly 100 is proposed. The base assembly 100 is used for a cooking device, and the cooking device has a cooking cavity 210. The base assembly 100 includes: a base 110, a steam generating assembly 120, and a blower 140. An installation cavity 111 is provided on the base 110. The installation cavity 111 has an exhaust port 112 and a gas supply port 113, and the gas supply port 113 is in communication with the exhaust port 112. The steam generating assembly 120 is connected to the base 110. The steam generating assembly 120 is provided with a steam inlet 121, a steam supply port 122, and an inner cavity 123. A steam flow channel 131 is provided in the inner cavity 123. The steam inlet 121 is in communication with the steam flow channel 131. The steam generated by the steam generating assembly 120 is used to be discharged into the cooking cavity 210 through the steam supply port 122, and the steam inlet 121 is used to supply the steam in the cooking cavity 210 to flow back into the steam flow channel 131. The blower 140 is located in the installation cavity 111, and the blower 140 is used to drive the steam flowing back into the steam flow channel 131 to be discharged from the exhaust port 112.

[0074] For the base assembly 100 provided in this embodiment, the steam generating assembly 120 is arranged on the base 110. When the steam generating assembly 120 operates, the steam generating assembly 120 heats the water in the inner cavity 123, so that the steam generating assembly 120 can generate steam. A steam supply port 122 is provided on the steam generating assembly 120, and the steam generated by the steam generating assembly 120 can be discharged into the cooking cavity 210 through the steam supply port 122, so that the ingredients in the cooking cavity 210 can be heated.

[0075] Figure 2 and Figure 3 The arrow directions in the cooking device are used to indicate the steam flow direction. Figure 8 The arrow directions in the steam flow channel 131 are used to indicate the steam flow direction.

[0076] A steam flow channel 131 is provided in the inner cavity 123, and the steam can heat the ingredients in the cooking cavity 210. As the amount of steam in the cooking cavity 210 gradually increases, the steam in the cooking cavity 210 can flow into the steam flow channel 131 from the steam inlet 121. Since there is water in the inner cavity 123, the steam flowing into the steam flow channel 131 can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The exhaust port 112 is in communication with the outside of the cooking device, and the steam flows through the steam flow channel 131 and is discharged outward through the exhaust port 112. That is, the steam in the steam flow channel 131 that has been cooled by heat exchange 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.

[0077] Moreover, during the heat exchange process between the steam and the water in the inner cavity 123, the heat of the high-temperature steam is transferred to the water, thereby realizing the recovery of the steam heat and avoiding waste of the steam heat. 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 123 can be quickly heated into steam, reducing the heating time of the water by the steam generating assembly 120, thereby reducing the energy consumption of the steam generating assembly 120 and being beneficial to improving the energy utilization rate.

[0078] When the blower 140 operates, the blower 140 is used to pump the steam in the steam flow channel 131 towards the exhaust port 112. Driven by the blower 140, 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 are quickly mixed 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, thereby avoiding the formation of condensed water.

[0079] An installation cavity 111 is provided on the base 110. The blower 140 is installed in the installation cavity 111, and the installation cavity 111 is used to connect the steam outlet and the exhaust port 112. By arranging the blower 140 in the installation cavity 111, the air flow flowing into the installation cavity 111 basically comes from the steam outlet, and it is not easy for the blower 140 to extract the air inside the base 110, so as to ensure that the steam in the steam flow channel 131 is discharged at a relatively high flow rate, further avoiding the formation of condensed water in the steam discharged from the cooking device.

[0080] After the steam discharged from the steam flow channel 131 is mixed with the external gas supplemented through the air supplement hole, the mixed gas is discharged through the steam outlet. The purpose of setting the air supplement hole is to increase the air flow rate, reduce the temperature of the discharged steam, and at the same time can reduce the negative pressure at the steam outlet, avoid the steam in the steam flow channel 131 from being discharged too fast, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0081] Combined Figure 4 and Figure 5 As shown, in some embodiments, optionally, the exhaust port 112 and the air supplement port 113 are arranged on different wall surfaces of the base 110.

[0082] The exhaust port 112 and the air supplement port 113 are both provided on the base 110. However, the exhaust port 112 and the air supplement port 113 need to be provided on different wall surfaces of the base 110. The exhaust port 112 is used to discharge steam outward, and the air supplement port 113 is used to allow ambient temperature gas from the outside to flow into the installation cavity 111. By providing the exhaust port 112 and the air supplement port 113 on different wall surfaces of the base 110, it is possible to effectively prevent the exhaust of the exhaust port 112 and the intake of the air supplement port 113 from interfering with each other, and prevent the just-discharged steam from being inhaled back into the installation cavity 111 through the air supplement port 113, ensuring that the temperature of the air flow inhaled into the installation cavity 111 through the exhaust is relatively low, thereby facilitating the cooling of the discharged steam.

[0083] Combined with Figure 4 and Figure 5 As shown, in some embodiments, optionally, the exhaust port 112 and the air supplement port 113 are provided on adjacent wall surfaces of the base 110.

[0084] By providing the exhaust port 112 and the air supplement port 113 on different wall surfaces of the base 110, it is possible to effectively prevent the exhaust of the exhaust port 112 and the intake of the air supplement port 113 from interfering with each other. In this case, the exhaust port 112 and the air supplement port 113 can be provided on adjacent wall surfaces of the base 110. The fan 140 typically has an axial intake and a side exhaust. When the exhaust port 112 and the air supplement port 113 are located on adjacent wall surfaces, the air supplement port 113 can correspond to the intake part of the fan 140, and the exhaust port 112 can correspond to the exhaust part of the fan 140, which is beneficial to increasing the air flow rate of the supplemented air, thereby effectively reducing the temperature of the steam and preventing scalding of the user.

[0085] Combined with Figure 4 and Figure 5 As shown, in some embodiments, optionally, the exhaust port 112 is provided on one side wall 114 of the base 110, and the air supplement port 113 is provided on the side wall 114 and / or the bottom wall 115 of the base 110.

[0086] When the exhaust port 112 is provided on the side wall 114 of the base 110, the air supplement port 113 can also be provided on the side wall 114 of the base 110, but the exhaust port 112 and the air supplement port 113 are provided on different side walls 114 of the base 110. Alternatively, when the exhaust port 112 is provided on the side wall 114 of the base 110, the air supplement port 113 can be provided on the bottom wall 115 of the base 110.

[0087] Combined with Figure 4 and Figure 5 As shown, in some embodiments, optionally, the base 110 is provided with feet 150, and the air supplement port 113 is higher than the bottom of the feet 150.

[0088] The base 110 is provided with feet 150 for supporting the base 110. The feet 150 can lift the base 110. When the feet 150 are placed on the workbench surface, there is a spaced arrangement between the base 110 and the workbench surface. When the air inlet 113 is provided on the bottom wall 115 of the base 110, there is a gap between the air inlet 113 and the workbench surface, and the workbench surface will not block the air inlet 113, so as to ensure that external gas can smoothly flow into the installation cavity 111 through the air inlet 113.

[0089] Combined Figure 4 with Figure 5 As shown, in some embodiments, optionally, an arc transition portion 116 is provided between the side wall 114 and the bottom wall 115 of the base 110, and the air inlet 113 is provided on the arc transition portion 116.

[0090] The side wall 114 and the bottom wall 115 of the base 110 are connected by the arc transition portion 116. The arc transition portion 116 is an arc-shaped structure, so that the side wall 114 and the bottom wall 115 of the base 110 are smoothly transitioned. The arc transition portion 116 bends upward compared with the bottom wall 115. When the air inlet 113 is provided on the arc transition portion 116, at least a part of the air inlet 113 is lifted higher than the bottom wall 115. Even if the base 110 is closely attached to the workbench surface, the air inlet 113 will not be blocked by the workbench surface, so as to ensure that external gas can smoothly flow into the installation cavity 111 through the air inlet 113.

[0091] In some embodiments, optionally, the opening area of the air inlet 113 is greater than or equal to the opening area of the exhaust port 112.

[0092] The opening area of the air inlet 113 is equal to the opening area of the exhaust port 112, or the opening area of the air inlet 113 is greater than the opening area of the exhaust port 112, so that the air inlet 113 can supplement sufficient air into the installation cavity 111.

[0093] Effectively reduce the negative pressure at the steam outlet.

[0094] As Figure 4 shown, in some embodiments, optionally, a recessed portion 117 is provided on the base 110, and the exhaust port 112 is provided on the inner wall of the recessed portion 117.

[0095] A recessed portion 117 is formed on the base 110, and the recessed portion 117 is recessed into the interior of the base 110. When the exhaust port 112 is provided on the inner wall of the recessed portion 117, it is not easy for the user to come into contact with the exhaust port 112. The steam just discharged through the exhaust port 112 still has a relatively high temperature. If the user directly leans against the vicinity of the exhaust port 112, they may be scalded by the high-temperature steam discharged from the exhaust port 112. Therefore, when the exhaust port 112 is provided in the recessed portion 117, it is not easy for the user to directly contact the exhaust port 112, thereby reducing the risk of the user being scalded by the steam.

[0096] In some embodiments, optionally, the wind speed s at the air outlet of the fan 140 satisfies s≥1 m / s.

[0097] The fan 140 has an air outlet, and the airflow blown by the fan 140 is discharged from the fan 140 through the air outlet. When the wind speed at the air outlet is greater than or equal to 1 m / s, it is beneficial to the rapid flow and diffusion of the steam, so that it is difficult to form visible water droplets or condensed water.

[0098] Combined Figure 2 、 Figure 4 and Figure 6 As shown in

[0099] In some embodiments, optionally, the steam generating assembly 120 includes: a water tank 124 and a juice collecting tray 125. The juice collecting tray 125 is connected to the water tank 124, and the inner cavity 123 is located between the juice collecting tray 125 and the water tank 124. The cooking cavity 210 is located above the juice collecting tray 125, and the juice collecting tray 125 is provided with a steam inlet 121 and a steam supply port 122.

[0100] The water tank 124 is used for storing water. The juice collecting tray 125 is arranged at the opening position of the water tank 124, and an inner cavity 123 is formed between the juice collecting tray 125 and the water tank 124. When the steam generating assembly 120 operates, the water in the water tank 124 is heated. After steam is generated in the water tank 124, the steam is discharged into the cooking cavity 210 through the steam supply port 122 on the juice collecting tray 125. Since the cooking cavity 210 is located above the juice collecting tray 125, the steam discharged from the steam supply port 122 directly enters the cooking cavity 210, thereby ensuring that the high-temperature steam can quickly heat the food ingredients.

[0101] In a possible application, the juice receiving tray 125 is placed on the water tank 124, allowing the user to pick up the juice receiving tray 125 to pour out the juice and facilitating the user to clean the interior of the water tank 124.

[0102] Combined with Figure 2 and Figure 7 As shown, in some embodiments, optionally, the steam generating assembly 120 further includes: a deflector 126, which is connected to the juice receiving tray 125, and a steam flow channel 131 is provided on the deflector 126.

[0103] The deflector 126 is provided with a steam flow channel 131, and the deflector 126 is used to direct the recovered steam so that the steam can flow along the deflector 126. Under the guiding action of the deflector 126, the steam exchanges heat with water along a set route, and the heat-exchanged steam can flow to the outside of the cooking device.

[0104] A part of the deflector 126 is immersed in water, so that the water can exchange heat with the deflector 126. In the case of steam flowing inside the steam, the steam can indirectly exchange heat with the water through the deflector 126.

[0105] Alternatively, an opening is provided at the bottom of the deflector 126, so that the steam flow channel 131 inside the deflector 126 is in direct contact with the water, enabling the steam to directly exchange heat with the water. A part of the deflector 126 is immersed in water, and the water acts as a barrier to the steam, ensuring that the steam can only flow inside the steam flow channel 131 and is not likely to flow out of the steam flow channel 131. That is, it can ensure that the steam can stably exchange heat with the water and can also ensure that the steam flow channel 131 can stably guide the steam.

[0106] Combined with Figure 3 and Figure 4 As shown, in some embodiments, optionally, the water tank 124 is provided with a vent hole 132, and the steam flow channel 131 and the installation cavity 111 are connected through the vent hole 132, and the opening area of the vent hole 132 is less than or equal to the opening area of the exhaust port 112.

[0107] The opening area of the vent hole 132 is equal to the opening area of the exhaust port 112, or the opening area of the vent hole 132 is less than the opening area of the exhaust port 112, which can prevent the steam in the cooking cavity 210 from being discharged outward too quickly and promote the full interaction between the steam and the fan 140, facilitating the diffusion of the steam and reducing the formation of condensed water in the air.

[0108] In some embodiments, optionally, the opening area of the vent hole 132 is greater than or equal to 50 mm 2 ; and / or the opening area of the exhaust port 112 is greater than or equal to 50 mm 2 .

[0109] When the opening area of the air guide hole 132 and the opening area of the exhaust port 112 satisfy the above range, it can ensure that the steam can smoothly discharge from the steam flow channel 131, avoiding excessive accumulation of steam in the steam flow channel 131.

[0110] Combined Figure 2 、 Figure 3 and Figure 4 As shown in, in some embodiments, optionally, the air guide hole 132 is located at the top of the installation cavity 111.

[0111] The air guide hole 132 is arranged in the upper part of the installation cavity 111, so that the air guide hole 132 has a relatively high position, and the water in the steam flow channel 131 is not easily introduced into the air guide hole 132, thereby avoiding the steam from carrying the water in the steam flow channel 131 out. Moreover, the above setting method can promote the diffusion of steam in the installation cavity 111, enable the steam to fully act on the fan 140, and promote the diffusion of steam in the air.

[0112] Combined Figure 2 、 Figure 3 and Figure 4 As shown in, in some embodiments, optionally, the air guide hole 132 is located at the top of the fan 140.

[0113] Setting the air guide hole 132 above the fan 140 makes the distance between the air guide hole 132 and the fan 140 relatively small, which is beneficial for the fan 140 to quickly extract the steam from the air guide hole 132.

[0114] Combined Figure 2 、 Figure 3 and Figure 4 As shown in, in some embodiments, optionally, the air guide hole 132 is located outside the installation cavity 111.

[0115] The air guide hole 132 extends out of the installation cavity 111. Even if a small amount of water contacts the air guide hole 132, the small amount of water is not easily introduced into the installation cavity 111, thereby avoiding the water in the steam water tank 124 from being introduced into the installation cavity 111.

[0116] Combined Figure 2 and Figure 9 As shown in. In some embodiments, optionally, the steam generating assembly 120 further includes: a partition 129, the partition 129 is located in the inner cavity 123, the partition 129 is used to separate the steam supply port 122 and the steam flow channel 131, a steam generating cavity 127 is provided on the partition 129, the steam generating cavity 127 is communicated with the inner cavity 123, and the steam supply port 122 is communicated with the steam generating cavity 127.

[0117] A partition 129 is provided in the inner cavity 123. The partition 129 can separate the steam supply port 122 and the steam flow path 131, making it difficult for the steam flowing towards the steam supply port 122 and the steam in the steam flow path 131 to mix with each other. Therefore, the steam generated from the heated water is not likely to flow into the steam flow path 131, and the steam flowing back into the steam flow path 131 is not likely to be discharged into the cooking cavity 210 again, ensuring that the steam flowing towards the cooking cavity 210 and the steam flowing back into the steam flow path 131 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.

[0118] A steam generation cavity 127 is provided in the partition 129. The steam generation cavity 127 is communicated with the steam supply port 122. The water in the steam generation cavity 127 will generate steam after being heated, and the steam in the steam generation cavity 127 is discharged into the cooking cavity 210 through the steam supply port 122. The partition 129 can define a steam generation cavity 127, and there is less water stored in the steam generation cavity 127. Therefore, the small amount of water in the steam generation cavity 127 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.

[0119] A water inlet hole 128 is provided on the partition 129. The water inlet hole 128 is used to communicate the steam generation cavity 127 and the inner cavity 123, and the water in the inner cavity 123 can be injected into the steam generation cavity 127 through the water inlet hole 128. When the water in the steam generation cavity 127 is heated into steam, the water in the inner cavity 123 is replenished into the steam generation cavity 127 through the water inlet hole 128 to prevent the water in the steam generation cavity 127 from being dried out. According to the principle of communicating vessels, the liquid level height in the steam generation cavity 127 is basically the same as the liquid level height in the inner cavity 123, thus ensuring that a small amount of water is maintained in the steam generation cavity 127.

[0120] In a possible application, the partition 129 is placed in the water tank 124, or the partition 129 is connected to the water tank 124.

[0121] As Figure 2 shown, in some embodiments, optionally, the steam generation assembly 120 further includes: a heating element 130, the heating element 130 is connected to the base 110, and the heating element 130 is disposed opposite to the steam generation cavity 127.

[0122] The heating element 130 faces the steam generation cavity 127 directly, so that the heating element 130 can only heat the water in the steam generation cavity 127, which is beneficial to improving the steam generation speed.

[0123] In some embodiments, optionally, the top of the partition 129 is hermetically sealed with the juice collector 125.

[0124] A seal is provided between the top of the separator 129 and the juice receiving tray 125, such that there is no gap between the top of the separator 129 and the juice receiving tray 125, preventing steam from passing over the separator 129 from the top thereof, thereby preventing the steam that has flowed back into the steam flow channel 131 from mixing with the newly generated steam in the steam generation chamber 127.

[0125] In a possible application, the juice receiving tray 125 overlaps the top of the separator 129 and is in contact with the separator 129, thereby forming a seal between the juice receiving tray 125 and the separator 129. Alternatively, the separator 129 and the juice receiving tray 125 are integrally provided.

[0126] Combined Figure 1 and Figure 2 As shown, in an embodiment 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, which will not be elaborated herein.

[0127] As Figure 2 shown, in some embodiments, optionally, the cooking device further includes: a steamer assembly 200. The steamer assembly 200 has a cooking chamber 210, and both the steam supply port 122 and the steam inlet 121 are in communication with the cooking chamber 210.

[0128] When the steam generation assembly 120 operates, the steam generation assembly 120 heats the water in the inner cavity 123, so that the steam generation assembly 120 can generate steam. A steam supply port 122 is provided on the steam generation assembly 120, and the steam generated by the steam generation assembly 120 can be discharged into the cooking chamber 210 through the steam supply port 122, thereby heating the food ingredients in the cooking chamber 210.

[0129] A steam flow channel 131 is provided in the inner cavity 123, and the steam can heat the food ingredients in the cooking chamber 210. As the amount of steam in the cooking chamber 210 gradually increases, the steam in the cooking chamber 210 can flow into the steam flow channel 131 through the steam inlet 121. Since there is water in the inner cavity 123, the steam flowing into the steam flow channel 131 can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The exhaust port 112 is in communication with the outside of the cooking device, and the steam flows through the steam flow channel 131 and is discharged outward through the exhaust port 112. That is, the steam in the steam flow channel 131 that has been cooled by heat exchange can be discharged from the cooking device. Since the temperature of the steam discharged from the cooking device is relatively low, 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.

[0130] As Figure 2As shown, in some embodiments, optionally, the cooking device further includes: a steam return pipe 300, a first end of the steam return pipe 300 is connected to the steam inlet 121, and a second end of the steam return pipe 300 extends towards the top of the cooking cavity 210.

[0131] One end of the steam return pipe 300 is connected to the steam inlet 121, 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 122, the steam will rise in the cooking cavity 210. Due to the relatively high height of the steam return pipe 300, only when the steam flows to the top of the cooking cavity 210 will the steam flow into the steam return pipe 300. Therefore, when a part of the steam flows to the top of the cooking cavity 210, the cooking cavity 210 is basically filled with steam, so that the temperature at each place in the cooking cavity 210 is relatively high, ensuring a uniform heating effect of the steam on the food ingredients.

[0132] By installing the steam return pipe 300 on the steam inlet 121, the steam is not likely to directly flow towards the steam inlet 121, ensuring that the steam can effectively heat the food ingredients.

[0133] 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 covers the steamer 220 to form a closed space inside the cover 230 and the steamer 220.

[0134] The food ingredients can be placed inside the steamer 220, and the space inside the cover 230 and the steamer 220 is the cooking cavity 210. When the cover 230 covers the inside of the steamer 220, the inside of the cover 230 and the steamer 220 is in a closed state, that is, no air holes for exhausting are provided on the cover 230, so that the gas inside the cooking cavity 210 will not be discharged outward 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 outward.

[0135] In the present utility model, the term "plurality" refers to two or more, unless otherwise clearly defined. Terms such as "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium.
