[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0047] Reference below Figure 1-Figure 11 The steam cooking device 100 according to the embodiment of the present application is described. The steam cooking device 100 can steam food by using steam.

[0048] The steam cooking device 100 according to the embodiment of the present application includes: a base 1 and a pot 2 .

[0049] The cooker 2 has a cooking cavity 201, in which food can be placed, and the cooking cavity 201 can be connected to the machine base 1, and the machine base 1 is provided with a steam conveying part, through which steam can be conveyed into the cooking cavity 201 to steam the food.

[0050] Reference Fig. 9 The cooker 2 is provided with a drainage head 21, which is connected to the cooking cavity 201. The water inlet end of the drainage head 21 is connected to the cooking cavity 201. The drainage end of the drainage head 21 is provided with a liquid blocking member 22. The liquid blocking member 22 can form a seal in the drainage head 21 through condensed water, thereby preventing the steam in the cooking cavity 201 from escaping from the drainage head 21, thereby ensuring the steam content in the cooking cavity 201.

[0051] Reference Figure 3 , Figure 5 and Figure 8 The machine base 1 is provided with a steam conveying portion and a drain port 15 which are arranged opposite to the side wall of the pot 2 .

[0052] When the cooker 2 is connected to the base 1, the steam delivery part is connected to the cooking cavity 201, and steam can be delivered to the cooking cavity 201 through the steam delivery part to increase the ambient temperature in the cooking cavity 201. At the same time, the drainage head 21 is connected to the drainage port 15, and the condensed water in the cooking cavity 201 can be discharged to the side of the drainage port 15 through the drainage head 21, so as to be drained to the side direction of the cooking cavity 201.

[0053] like Figure 5 As shown, the steam cooking device 100 is further provided with a water receiving box 3, which is arranged on the base 1 and connected to the drain port 15 to connect the water receiving box 3 with the drain head 21, and collect condensed water through the water receiving box 3.

[0054] Reference Figure 5 It can be understood that the drain head 21 is arranged on the side wall of the pot 2, and the water in the cooking cavity 201 can be discharged through the drain head 21 to reduce the condensed water in the cooking cavity 201. The drain head 21 extends from the side wall of the pot 2 to the side away from the cooking cavity 201 to form a drainage channel arranged horizontally (i.e., to the side of the drain port 15). When the liquid blocking member 22 is arranged on the drain head 21, the liquid blocking member 22 can form a sealing structure in the water receiving head through condensed water. The sealing structure is formed by the cooperation of the condensed water and the liquid blocking member 22, and cannot allow steam to pass through, thereby preventing steam from escaping from the drain head 21 and ensuring the steam content in the cooking cavity 201.

[0055] It should be noted that the steam cooking device 100 generates condensed water during the process of steaming and cooking food. In the related art, a water receiving pan is provided inside the cooking device to collect the condensed water, but the water receiving pan occupies the space of the cooking cavity 201. If a waste water box connected to the cooking cavity 201 is provided outside the cooking cavity 201, there is a problem of steam escaping from the connection between the waste water box and the cooking cavity 201, which affects the cooking effect and cooking efficiency of the steam cooking device 100 on the food.

[0056] In the present application, the water receiving box 3 is arranged on the outside of the cooking cavity 201, and is an independent receiving component that does not occupy the internal space of the cooking cavity 201. A liquid blocking member 22 is provided at the drainage head 21. Through the cooperation of the liquid blocking member 22 and the condensed water, a sealing structure that allows condensed water to pass through but steam cannot pass through can be formed in the water receiving head, thereby preventing the steam in the cooking cavity 201 from escaping, ensuring the steam content in the cooking cavity 201, and improving the cooking effect of the steam cooking device 100.

[0057] like Figure 5 and Fig. 9 As shown, the drainage head 21 is arranged on the side wall of the pot 2 and is located on a side adjacent to the bottom wall, so that the condensed water can be collected through the drainage head 21 .

[0058] It is understandable that when condensed water is generated in the cooking cavity 201, under the action of gravity, the condensed water will gather at the bottom of the cooking cavity 201. By setting the drain head 21 on the side adjacent to the bottom wall of the pot 2, the condensed water in the cooking cavity 201 can be easily discharged through the drain head 21.

[0059] like Figure 1 and Figure 3 As shown, in some embodiments of the present application, the steam cooking device 100 further includes: a steam generating device 4 and a water tank 5, wherein the steam generating device 4 is used to generate steam, and the steam generating device 4 can deliver steam to the steam delivery part, and further deliver steam to the cooking cavity 201 through the steam delivery part.

[0060] Reference Figure 1 and Figure 3 The water tank 5 is arranged on the machine base 1, and the water tank 5 is used to store the liquid medium. The water tank 5 can transport the liquid medium to the steam generating device 4, and the liquid medium can be heated by the steam generating device 4 to form high-temperature steam.

[0061] In some embodiments of the present application, the side wall of the drainage head 21 of the sub-cooker 2 extends to a side away from the cooking cavity 201 and forms a drainage channel, which is arranged in a transverse direction (eg, horizontal direction).

[0062] Reference Fig. 9 The liquid blocking member 22 includes: a first baffle 221 and a second baffle 222. When the liquid blocking member 22 is connected and matched with the drainage head 21, the first baffle 221 is arranged in the drainage channel, and the first baffle 221 extends from top to bottom, and the second baffle 222 is also arranged in the drainage channel, and the second baffle 222 is located downstream of the first baffle 221 (i.e., the side of the drainage channel away from the cooking cavity 201), and the second baffle 222 extends from bottom to top, and the upper end of the second baffle 222 is higher than the lower end of the first baffle 221.

[0063] Reference Fig. 9 The first baffle 221 and the second baffle 222 are arranged at intervals in the drainage channel, and the first baffle 221 and the second baffle 222 have a blocking effect on condensed water, so that a water accumulation section can be formed between the first baffle 221 and the second baffle 222, and when the water level of the water accumulation section reaches the upper end surface of the second baffle 222, the condensed water can pass over and be discharged from the liquid blocking member 22.

[0064] Reference Fig. 9It can be understood that when condensed water flows into the drainage channel, the second baffle 222 extending from bottom to top has a blocking effect on the condensed water, so that when the water level in the drainage channel does not reach the upper end surface of the second baffle 222, the condensed water cannot flow out over the second baffle 222. At the same time, the first baffle 221 is arranged from top to bottom, and when the water level of the condensed water in the drainage channel blocked by the second baffle 222 reaches the lower end surface of the first baffle 221, there is no gap between the condensed water and the first baffle 221, so that a water accumulation section (i.e., the above-mentioned sealing structure) is formed between the first baffle 221 and the second baffle 222, and when the water level of the water accumulation section between the first baffle 221 and the second baffle 222 reaches the height of the second baffle 222, if more condensed water flows into between the first baffle 221 and the second baffle 222, the condensed water can be discharged over the second baffle 222.

[0065] Among them, when the water level of the condensed water in the drainage channel reaches the lower end surface of the first baffle 221, the condensed water in the drainage channel is sealed with the first baffle 221, and the steam in the cooking cavity 201 cannot pass through the first baffle 221, thereby preventing the steam in the cooking cavity 201 from being discharged through the drainage channel.

[0066] At the same time, when the water level of the condensed water reaches the lower end of the first baffle 221, a seal can be formed in the drainage channel, and as the condensed water in the cooking cavity 201 increases, the water level of the water accumulation section between the first baffle 221 and the second baffle 222 will also increase accordingly, and will be discharged when the water level of the water accumulation section reaches the upper end of the second baffle 222.

[0067] It should be noted that the cooker 2 is provided with an exhaust structure (such as an exhaust hole), which can be used to connect the cooking cavity 201 with the outside world to maintain the pressure balance in the cooking cavity 201 and prevent the pressure in the cooking cavity 201 from being too high. The drainage end of the drainage head 21 is connected to the water receiving box 3, so that a communicating vessel structure can be formed in the drainage channel through the liquid blocking member 22. The water level of the condensed water on the left side of the first baffle 221 is the same as the water level of the water accumulation section between the first baffle 221 and the second baffle 222. As the amount of condensed water flowing into the drainage channel increases, the water level in the drainage channel also increases, so that the condensed water can pass over the second baffle 222 and be discharged.

[0068] like Fig.10As shown, in some embodiments of the present application, the liquid blocking member 22 is constructed as a hollow columnar structure, and the columnar structure is plugged into the drainage channel. In the plug-in installation direction, the first baffle 221 is formed at the end of the columnar structure, the second baffle 222 is formed in the middle of the columnar structure, and the columnar structure forms a gap between the first baffle 221 and the second baffle 222. The first baffle 221 and the second baffle 222 define an opening that opens downward at the gap, and the above-mentioned water accumulation section can be formed at the opening.

[0069] Reference Fig.11 , the water outlet area formed by the columnar structure is S, in the projection of the plug-in installation direction, the area where the second baffle 222 overlaps with the water outlet is S1, and the area where the notch overlaps with the water outlet at the first baffle 221 is S2, and the relationship is satisfied: S2<S1<S. As a result, when condensed water flows into the liquid blocking member 22, it needs to turn over the second baffle 222 before it can further flow to the water receiving box 3, and a water accumulation section can be formed between the first baffle 221 and the second baffle 222, and a self-seal is formed at the water accumulation section.

[0070] It should be noted that the smaller the parameters of S1 and S2 are, the less condensed water remains in the drainage channel.

[0071] Reference Fig.10 The columnar structure in the present application is cylindrical, but the specific shape of the liquid blocking member 22 is not limited here. The shape of the liquid blocking member 22 needs to be compatible with the inner wall shape of the drainage head 21 to ensure the connection reliability between the liquid blocking member 22 and the drainage head 21.

[0072] The liquid blocking member 22 is connected to the drain head 21 by interference fit to prevent the liquid blocking member 22 from coming out of the drain head 21. Of course, the liquid blocking member 22 can also be assembled to the drain head 21 by bonding, threaded connection, ultrasonic welding, etc.

[0073] like Fig. 9 As shown, in some embodiments of the present application, the liquid blocking member 22 is plugged into and matched with the drain head 21, and a limiting flange 223 is provided at the end of the liquid blocking member 22. The limiting flange 223 and the end of the drain head 21 away from the cooking cavity 201 are abutted against each other to limit the position, so as to reduce the difficulty of assembling the liquid blocking member 22 and the drain head 21.

[0074] like Fig. 9 As shown, in some embodiments of the present application, the inner bottom surface of the cooking cavity 201 formed by the pot 2 is inclined from top to bottom toward the side of the drainage head 21, so that the condensed water in the inner bottom surface can gather toward the side of the drainage head 21, which facilitates the condensed water to flow into the drainage head 21, thereby ensuring the condensed water discharge effect of the cooking cavity 201.

[0075] Among them, the condensed water in the cooking cavity 201 will flow to the bottom of the cooking cavity 201 under the action of gravity, and because the inner bottom surface is inclined toward the side of the drainage head 21, the condensed water will gather toward the side of the drainage head 21, so that the condensed water can flow into the drainage head 21. It can be understood that a liquid blocking member 22 is provided in the drainage head 21, and a sealing structure is formed in the drainage channel through the liquid blocking member 22 to prevent steam from escaping, and the sealing structure is formed by the condensed water and the liquid blocking member 22. In other words, when the water level in the drainage channel reaches a preset condition (i.e., reaches the upper end surface of the second baffle 222), it can be discharged, and the inner bottom surface of the pot 2 is inclined, so that the condensed water can be gathered toward the side of the drainage head 21, and a small amount of condensed water can cooperate with the liquid blocking member 22 to form a sealing structure.

[0076] Reference Fig. 9 In a further embodiment of the present application, the inner bottom surface of the pot 2 is constructed as a guiding slope, and the angle between the plane where the guiding slope is located and the horizontal plane is α, and the relationship is satisfied: 3°≤α≤20°. Thus, the guiding slope has a guiding effect on the condensed water at the bottom of the cooking cavity 201.

[0077] The drain head 21 in the present application is arranged on the side wall of the pot 2, so that the condensed water can be discharged from the side, saving vertical space, and the drain head 21 is arranged close to the bottom wall. Under the action of the guiding slope, the condensed water can flow into the drain head 21, which is convenient for the condensed water to be discharged from the cooking cavity 201.

[0078] like Figure 5 As shown, in some embodiments of the present application, in the vertical direction, the water receiving box 3 is arranged lower than the cooking cavity 201, so that the water receiving box 3 can collect the condensed water. It can be understood that the condensed water in the pot 2 is discharged laterally. If the height of the water receiving box 3 is not lower than the bottom wall of the cooking cavity 201, it will increase the difficulty of discharging the condensed water in the cooking cavity 201.

[0079] like Figure 8 As shown, in some embodiments of the present application, the base 1 includes: a first base body 11 and a second base body 12, the first base body 11 is used to place the pot 2. The second base body 12 is connected to the first base body 11 and is located on the side of the pot 2. The steam delivery part is provided on a side surface of the second base body 12 opposite to the pot 2 to deliver steam from the side of the pot 2 to the cooking cavity 201.

[0080] The upper surface of the first seat body 11 is configured as a placement area for the pot 2, which is used to place the pot 2, so as to facilitate the overall transport of the steam cooking device 100. The second seat body 12 is arranged on one side of the first seat body 11 and extends upward in the vertical direction. When the pot 2 is arranged on the first seat body 11, the second seat body 12 is arranged opposite to the side wall of the pot 2, and the steam delivery part and the drain port 15 are both arranged on the side wall of the second seat body 12 opposite to the pot 2. The pot 2 can be connected and matched with the second seat body 12 by side installation.

[0081] It can be understood that the steam delivery part and the pot 2 can be connected by plugging, and the drainage head 21 on the pot 2 can be inserted into the drain port 15 by plugging. The assembly method of the pot 2 and the machine base 1 is simple, which is convenient for users to disassemble and assemble the pot 2 and reduce the difficulty of cleaning the pot 2.

[0082] In some embodiments of the present application, there are multiple steam delivery parts, and the cooking cavity 201 is connected to at least two steam delivery parts, so that the temperature inside the cooking cavity 201 is more uniform. At the same time, taking the cooking cavity 201 being connected to two steam delivery parts as an example, when steam is delivered to the cooking cavity 201 through the two steam delivery parts, forced convection can be formed in the cooking cavity 201, thereby accelerating the heating efficiency of the food.

[0083] like Figure 2 As shown, in some embodiments of the present application, in the vertical direction, the communication position between the steam delivery part and the cooking cavity 201 is higher than the communication position between the drainage head 21 and the cooking cavity 201 to ensure the steam delivery effect.

[0084] Reference Figure 3 In the present application, steam is transported to the cooking cavity 201 through the same side wall of the second seat body 12, and the condensed water is collected. The steam transport part is arranged above the drainage head 21, which can prevent the condensed water from flowing back at the steam transport part.

[0085] like Figure 8 As shown, in some embodiments of the present application, the first seat body 11 is provided with a guide portion, which is used to guide the cooker 2 in the installation direction of the cooker 2 and the second seat body 12, thereby reducing the difficulty of assembling the cooker 2 to the base 1.

[0086] Combination Figure 3 and Figure 8 The steam spray head 131 extends in the horizontal direction, and the upper surface of the first base body 11 is horizontally arranged and used to place the pot 2. When the pot 2 needs to be connected with the steam spray head 131, the pot 2 needs to be moved in the horizontal direction to be plugged and connected with the steam spray head 131. The guide part on the first base body 11 can play a good guiding role for the pot 2 to assist the user in assembling the pot 2.

[0087] In some embodiments of the present application, the guide portion is constructed as a guide protrusion 111, which is arranged on the upper surface of the first seat body 11, and a guide groove 112 is formed at the guide protrusion 111, and the extension direction of the guide groove 112 is parallel to the installation direction of the cookware 2.

[0088] Furthermore, a guide block is provided on the bottom wall of the pot 2, the guide block protrudes downward, and the guide block can be matched with the guide groove 112. When the pot 2 is connected and matched with the second base 12, the guide block is embedded in the guide groove 112, and by pushing the pot 2 to move relative to the base 1, the pot 2 can be plugged and matched with the steam conveying part, and the drain head 21 can be plugged and matched with the drain port 15, thereby reducing the difficulty of installing the pot 2.

[0089] Reference Figure 8 The opening of the guide groove 112 away from the second seat body 12 is gradually expanded to guide the guide block at the bottom of the pot 2, so as to facilitate the alignment of the pot 2 and the second seat body 12.

[0090] Reference Figure 5 and Figure 8 In some embodiments of the present application, the second base body 12 is provided with an installation cavity 121, which is located at the bottom of the second base body 12, and the top wall of the installation cavity 121 is provided with a liquid outlet 122 which is open downward and connected to the drain port 15. The condensed water flowing into the drain port 15 through the drainage channel can flow into the liquid outlet 122 and be further discharged through the liquid outlet 122.

[0091] Furthermore, the water receiving box 3 is arranged in the installation cavity 121, and the water receiving box 3 is provided with a water receiving groove with an open upper end, and the liquid outlet 122 is arranged opposite to the open end of the water receiving groove, and the condensed water at the discharge end of the liquid outlet 122 can flow into the water receiving groove and be collected by the water receiving groove. It can be understood that by forming the discharge structure of the condensed water on the second base 1, it is convenient to guide the water discharged through the drain port 15 to a position suitable for receiving the water receiving box 3. Among them, the water receiving box 3 can be installed in the installation cavity 121 in a retractable manner, so that the user can handle the condensed water in the water receiving box 3.

[0092] like Figure 6 As shown, in some embodiments of the present application, the first seat body 11 is provided with a positioning assembly 16, and the positioning assembly 16 is protruding from the first seat body 11 toward one side of the bottom wall of the cookware 2. The cookware 2 is provided with a positioning portion 24. When the pot assembly 2 is connected to the steam delivery portion, the positioning portion is positioned and matched with the positioning assembly.

[0093] The positioning portion 24 is disposed on a side surface of the cookware 2 opposite to the first base 11, that is, on the bottom wall of the cookware 2. In the present application, when the cookware includes a first cookware 231 and a second cookware 232 stacked together, the positioning portion 24 can be disposed at the bottom wall of the first cookware 231 located below and placed on the first base 11, so as to be positioned and matched with the positioning assembly 16 disposed on the first base 11.

[0094] It is understandable that the pot 2 is connected to the steam delivery part, and the specific connection method can be plug-in connection, etc. Taking the plug-in connection method as an example, when the pot 2 is connected to the steam delivery part, it is necessary to prevent the pot 2 from being separated from the steam delivery part, so the positioning component 16 and the positioning part 24 can be used to position the pot 2 and the first seat 11.

[0095] In some embodiments of the present application, the first seat body 11 is provided with a mounting groove 1631 open to one side of the cookware 2, and the positioning assembly 16 includes: a positioning member 161 and an elastic member 162, the positioning member 161 can be movably installed in the mounting groove 1631 along the vertical direction, and at least a portion of the positioning member 161 protrudes from the upper surface of the first seat body 11, the elastic member 162 is elastically supported between the positioning member 161 and the wall of the mounting groove 1631, and the elastic member 162 is suitable for storing energy when the positioning member 162 moves into the mounting groove 1631.

[0096] It is understandable that when the pot set 2 is not assembled in place, the bottom wall of the pot 2 can press against the positioning member 161 to compress the positioning member 161 into the installation groove 1631. When the pot 2 presses against the positioning member 161, the positioning member 161 can compress the elastic member 162, and the elastic member 162 stores energy. The elastic member 162 can release energy when the positioning member 161 cooperates with the positioning portion 24 to reset the positioning member 161.

[0097] Among them, the positioning portion 24 can be constructed as a positioning seat, and the positioning seat is formed with a groove structure open to one side of the first seat body 11. When the positioning piece 161 is positioned and matched with the positioning portion, the part of the positioning piece 161 protruding from the first seat body 11 can be embedded in the groove structure to position and match the cookware 2 with the first seat body 11.

[0098] In some embodiments of the present application, the positioning assembly 16 further includes a fixing member 163 , which is disposed on the first base 11 and forms the above-mentioned mounting groove 1631 to mount the positioning member 161 and the elastic member 162 on the fixing member 163 .

[0099] Reference Figure 7 The positioning member 161 can be arranged to penetrate the bottom wall of the fixing member 163 so as to guide the movement direction of the positioning member 161 through the hole structure formed on the bottom wall of the fixing member 163 .

[0100] Reference Figure 2 In some other embodiments of the present application, the second base body 12 includes a mounting plate 123 , which can be fixed to the second base body 12 by snap-fitting and is configured as a top wall of the mounting cavity 121 .

[0101] The clamping structure can be configured as a hook, a buckle, etc., which is not specifically limited here. When the mounting plate 123 is configured as the top wall of the mounting cavity 121, the liquid outlet 122 can be formed on the mounting plate 123. Further, a slide groove is formed at the bottom of the mounting plate 123, and the slide groove can cooperate with the water receiving box 3 to guide the water receiving box 3.

[0102] In some embodiments of the present application, a detection component is disposed on the first base 11 , and the detection component can be used to detect whether the pot 2 is properly installed on the base 1 , so as to improve the safety and reliability of the steam cooking device 100 .

[0103] It is understandable that if the pot 2 is not properly assembled, the steam delivered by the steam delivery unit may leak out, resulting in the inability to deliver the steam to the cooking cavity 201 or only a small amount of steam to the cooking cavity 201, affecting the cooking effect and posing a safety hazard. The steam cooking device 100 can be configured such that: when it is detected that the pot 2 is properly assembled, the steam generating device 4 does not work.

[0104] It should be noted that the detection component may be a micro switch, and the micro switch may be triggered when the cooker 2 is assembled to the first seat 11. Of course, the specific structure of the detection component is not limited thereto.

[0105] like Figure 5 As shown, in some embodiments of the present application, the liquid outlet 122 and the drain outlet 15 are connected via a drain pipe 14, and the condensed water discharged through the drain outlet 15 can flow to the liquid outlet 122 through the drain pipe 14, thereby guiding the condensed water to the liquid outlet 122, making it convenient to collect the condensed water through the water receiving box 3.

[0106] In some embodiments of the present application, a plurality of steam delivery parts are provided on the machine base 1, and the pot 2 includes: a first pot 231 and a second pot 232. The first pot 231 has a first cooking cavity 2011, and the first cooking cavity 2011 is connected to at least one steam delivery part, so that steam is delivered to the first cooking cavity 2011 through the steam delivery part; the second pot 232 is stacked on the first pot 231, and the second pot 232 has a second cooking cavity 2012, and the second cooking cavity 2012 is connected to at least one steam delivery part, so that steam is delivered to the second cooking cavity 2012 through the steam delivery part.

[0107] It is understandable that when there are multiple cookers 2, multiple relatively independent cooking cavities 201 can be formed, and each installation cavity 121 can be connected to the steam delivery part respectively, and the machine base 1 can deliver steam to the multiple cooking cavities 201 respectively through the multiple steam delivery parts.

[0108] Reference Figure 3 and Figure 8 Four steam conveying parts are provided on the machine base 1, and the four steam conveying parts are grouped in pairs and are respectively connected to an installation cavity 121, such as: the two steam conveying parts located at the top are connected to the second cooking cavity 2012, and steam can be transported to the second cooking cavity 2012 through the two upper steam conveying parts; the two steam conveying parts located at the bottom are connected to the first cooking cavity 2011, and steam can be transported to the first cooking cavity 2011 through the two lower steam conveying parts, so as to meet the cooking needs of the first pot 231 and the second pot 232 for steaming food.

[0109] The base 1 is provided with a corresponding number of drain ports 15 corresponding to the number of the pots 2. Figure 6 Two drainage ports 15 spaced apart in the vertical direction are provided on the machine base 1. The two drainage ports 15 are respectively used to communicate with the first cooking cavity 2011 and the second cooking cavity 2012 so as to collect condensed water in the first cooking cavity 2011 and the second cooking cavity 2012 at the same time through the water receiving box 3.

[0110] It should be noted that in the related art, when a plurality of independent cooking cavities 201 are formed in the steam cooking device 100, a water collecting tray needs to be provided in each cooking cavity 201 respectively so as to collect the condensed water in each cooking cavity 201 through the water collecting tray, resulting in a large number of water collecting trays in the steam cooking device 100, and after cooking, the plurality of water collecting trays need to be cleaned separately, resulting in a large amount of cleaning workload for the user.

[0111] In the present application, two relatively independent cooking chambers 201 (i.e., the first cooking chamber 2011 and the second cooking chamber 2012) are provided in the steam cooking device 100, and the ingredients can be cooked separately through the two cooking chambers 201 to prevent the ingredients from having mixed flavors. At the same time, the first cooking chamber 2011 and the second cooking chamber 2012 are respectively connected to the two drainage ports 15 of the machine base 1, and the condensed water in the first cooking chamber 2011 and the second cooking chamber 2012 can be discharged through the two drainage ports 15 respectively, and the two drainage ports 15 can be discharged to the water receiving box 3 through the drainage pipe 14, so that the condensed water in the two cooking chambers 201 can be uniformly collected through the water receiving box 3, so that the user can uniformly process the condensed water.

[0112] Reference Figure 5A plurality of liquid outlets 122 may be formed on the top wall of the mounting cavity 121 , each liquid outlet 122 corresponds to a drain port 15 , and a drain pipe 14 is provided between each group of drain ports 15 and the liquid outlet 122 , and the drain pipe 14 is used to connect the drain port 15 with the liquid outlet 122 .

[0113] In some embodiments of the present application, a first connecting seat 2311 is provided on the top surface of the first pot 231 , and a second connecting seat 2321 is provided on the bottom wall of the second pot 232 , and the first connecting seat 2311 is connected and matched with the second connecting seat 2321 .

[0114] The first connection seat 2311 and the second connection seat 2321 can be assembled to the machine base 1 together after being connected and matched, thereby reducing the difficulty of installing the first pot 231 and the second pot 232.

[0115] It is understandable that the first pot 231 and the second pot 232 are connected to the second base body 12 by plugging, and the first pot 231 and the second pot 232 are arranged in a stacked manner. If the first pot 231 and the second pot 232 are installed in the second base body 12 by horizontal plugging, the operation is difficult.

[0116] In the present application, the first pot 231 and the second pot 232 are connected by the first connection seat 2311 and the second connection seat 2321, and after the connection, the first pot 231 and the second pot 232 can be assembled to the machine base 1 together by horizontal plugging. The first pot 231 located at the bottom is provided with the above-mentioned guide block, which cooperates with the guide groove to guide the first pot 231 in the plugging direction. The first pot 231 and the second pot 232 have the same installation direction, and the first pot 231 can drive the second pot 232 to move synchronously, so that the first pot 231 and the second pot 232 can be assembled to the machine base 1 together.

[0117] In some embodiments of the present application, the first connecting seat 2311 is provided with a positioning groove open to one side of the second pot 232 , and at least a portion of the second connecting seat 2321 is embedded in the positioning groove to install the second pot 232 on the first pot 231 .

[0118] Therefore, through the cooperation of the first connecting seat 2311 and the positioning groove, the second pot 232 can be assembled to the first pot 231 by plugging from top to bottom. The assembly method is simple, and when the second connecting seat 2321 is embedded in the first connecting seat 2311, the movement of the second pot 232 relative to the first pot 231 can be restricted in the horizontal direction, so that the first pot 231 and the second pot 232 can be connected and cooperated with the second seat body 12 together.

[0119] like Figure 3As shown, in some embodiments of the present application, the side wall of the first pot 231 forms a first door body 2312, and the first door body 2312 is arranged opposite to the drain outlet 15, so that the first door body 2312 is arranged on the side of the first pot 231 away from the drain outlet 15 to prevent condensed water from being discharged through the first door body 2312 when the first door body 2312 is opened.

[0120] like Figure 3 As shown, in some embodiments of the present application, the side wall of the second pot 232 forms a second door body 2322, and the second door body 2322 is arranged opposite to the drain outlet 15, so that the second door body 2322 is arranged on the side of the first pot 231 away from the drain outlet 15 to prevent condensed water from being discharged through the second door body 2322 when the second door body 2322 is opened.

[0121] It is understandable that when the inner bottom wall of the cooker 2 is configured to direct condensed water toward the drain port 15 , arranging the door body on the side opposite to the drain port 15 can effectively prevent condensed water from flowing out of the cooking cavity 201 .

[0122] Reference Figure 1 and Figure 2 A handle is provided on the door body, and the user can open or close the door body by holding the handle. The door body (such as the first door body 2312 and the second door body 2322) is configured to be flippable from top to bottom. When the door body is flipped downward and opened, a clearance can be formed above the door body opening position, which is convenient for putting food into the cooking cavity 201 or taking food out of the cooking cavity 201.

[0123] In some embodiments of the present application, the volume of the first cooking cavity 2011 is greater than the volume of the second cooking cavity 2012, so that larger ingredients can be cooked in the first cooking cavity 2011, thereby meeting the cooking needs for larger ingredients.

[0124] In some embodiments of the present application, the steam generating device 4 includes a steam generator 41 and a liquid pump 42. The steam output end of the steam generator 41 is connected to the steam delivery part, the liquid inlet end of the steam generator 41 is connected to the liquid pump 42, and the liquid pump 42 is connected to the water tank 5. The liquid medium in the water tank 5 can be pumped to the steam generator 41 through the liquid pump 42. The steam generator 41 heats the liquid medium to convert the liquid medium into high-temperature steam, and further transports it to the cooking cavity 201 through the steam delivery part.

[0125] In the present application, the water tank 5 can be installed on the second base 12, and the steam generating device 4 is arranged in the cavity of the second base 12. When a plurality of pots 2 are provided in the steam cooking device 100, a plurality of steam generating devices 4 can be provided, and each steam generating device 4 can deliver steam to at least one cooking cavity 201. For example: Figure 3 When the steam cooking device 100 is provided with a first pot 231 and a second pot 232, there are two steam generating devices 4, and the two steam generating devices 4 are respectively used to deliver steam to the first cooking cavity 2011 and the second cooking cavity 2012. Thus, steam can be delivered to the two cooking cavities 201 according to cooking needs, enriching the cooking modes of the steam generating device 4.

[0126] like Figure 4 As shown, in some embodiments of the present application, the steam delivery part is configured as a steam spray head 131, which is mounted on the housing of the base 1, and one end of the steam spray head 131 is connected to the steam generating device 4, and the other end of the steam spray head 131 can be connected and matched with the pot 2 to communicate with the cooking cavity 201. When steam is delivered to the steam spray head 131, the steam spray head 131 can further radially deliver steam into the cooking cavity 201.

[0127] The steam nozzle 131 can be connected to the cooker 2 by plugging, and the connection method is simple and has high reliability.

[0128] like Figure 4 As shown, in a further embodiment of the present application, a nozzle sealing ring 132 is provided on the steam nozzle 131, and the nozzle sealing ring 132 is sleeved on the steam nozzle 131, and when the steam nozzle 131 is plugged into the pot 2, the nozzle sealing ring 132 is clamped between the socket wall of the pot 2 and the steam nozzle 131, so as to form a seal between the steam nozzle 131 and the pot 2, improve the sealing between the steam nozzle 131 and the pot 2, and prevent steam from escaping from the gap at the connection between the steam nozzle 131 and the pot 2.

[0129] Reference Figure 4 In the installation direction, the nozzle sealing ring 132 gradually expands from the side of the pot 2 to the side away from the cooking cavity 201. The gradually expanding nozzle sealing ring 132 can play a guiding role, reducing the difficulty of connecting the pot 2 and the steam nozzle 131 while further improving the sealing effect.

[0130] like Figure 4 As shown, in some embodiments of the present application, the nozzle sealing ring 132 is formed with a buffer flange 1321, and the buffer flange 1321 is suitable for protruding along the radial direction toward the side away from the steam nozzle 131, and when the pot 2 is connected to the steam nozzle 131, the buffer flange 1321 can be clamped between the pot 2 and the machine base 1 to buffer the impact force between the pot 2 and the machine base 1 during installation.

[0131] In some embodiments of the present application, the steam nozzle 131 is further provided with a positioning flange 1312 , which is embedded and matched with the nozzle sealing ring 132 to position the steam nozzle 131 and the nozzle sealing ring 132 to prevent the nozzle sealing ring 132 from falling off the steam nozzle 131 .

[0132] In some embodiments of the present application, a threaded connection section 1311 is formed on the steam nozzle 131, and the threaded connection section 1311 is passed through the outer shell of the machine base 1 and threadedly cooperates with a threaded connection member (such as a bolt 133) arranged in the machine base 1 to install the steam nozzle 131 on the machine base 1.

[0133] According to the steam cooking device 100 of the embodiment of the present application, cooking can be performed by lateral steam delivery, and steam can be delivered between multiple cooking cavities 201 respectively through multiple steam generating devices 4, so that the cooking rate of the food in each cooking cavity 201 can be controlled and adjusted.

[0134] At the same time, the condensed water in multiple cooking cavities 201 can be collected uniformly through the water collecting box 3, and a sealing structure can be formed at the drainage head 21 of the cooker 2 to effectively prevent the steam in the cooking cavity 201 from escaping from the drainage head 21, thereby ensuring the cooking effect of the cooking utensil.
